                                  RISK FACTORS
 
     The following factors, as well as the information under "Risk Factors"
contained in the accompanying prospectus beginning on page 5 and the information
contained elsewhere or incorporated by reference in this prospectus supplement
or the accompanying prospectus, should be carefully considered by prospective
investors before any decision is made to invest in the notes.
 
FAILURE OR DELAY IN ACHIEVING THE EXPECTED BENEFITS OF THE KUHLMAN MERGER
 
     As described under "Recent Developments" below, we have entered into a
merger agreement to acquire Kuhlman Corporation. We believe that significant
business opportunities and cost savings are achievable as a result of the
merger. Estimates of cost savings are based upon many assumptions, including
future sales levels and other operating results, ability to eliminate excess
costs, ability to achieve cost reductions on future purchases of raw materials,
availability of funds for capital expenditures, as well as general industry and
business conditions and other matters, many of which are beyond the control of
the combined company. Estimates of potential cost savings are forward-looking
statements that are inherently uncertain. The combined company's actual cost
savings, if any, could differ from those projected and such differences could be
material. Therefore, you should not unduly rely on our estimates as predictors
of actual cost savings. Unforeseen costs and expenses or other factors (whether
arising in connection with the integration of the two companies' operations or
otherwise) may offset the estimated cost savings or other components of the
combined company's projected performance and may result in delays in the
realization of certain projected cost savings.
 
FAILURE OR DELAY IN SELLING KUHLMAN'S ELECTRICAL PRODUCTS BUSINESSES
 
     After completion of the merger, we expect to sell Kuhlman's electrical
products businesses. However, we have not yet solicited potential buyers, and
there can be no assurance that we will be able to sell the electrical products
businesses on favorable terms. If we are unable to sell the businesses on
favorable terms, our capital structure, cost of borrowing, and financial
position could be adversely affected.
 
                                  THE COMPANY
 
     We are a leading, global supplier of highly engineered systems and
components, primarily for automotive powertrain applications. Our products are
manufactured and sold worldwide, primarily to original equipment manufacturers
of passenger cars, sport utility vehicles and light trucks. We operate 35
manufacturing facilities in 12 countries serving North America, Europe and Asia,
and we are an original equipment supplier to every major original equipment
manufacturer in the world. For additional information regarding our four
operating groups, see the section called "The Company" in the accompanying
prospectus.
 
     Our executive offices are located at 200 South Michigan Avenue, Chicago,
Illinois 60604, telephone (312) 322-8500.

                              RECENT DEVELOPMENTS
 
RECENT FINANCIAL RESULTS
 
     On February 8, 1999, we reported that our fourth quarter 1998 net income
was $31.8 million, or $1.35 per share, an increase of 18% per share compared
with $27.2 million, or $1.14 per share, for the fourth quarter of 1997. Our
sales for the fourth quarter of 1998 increased to $489 million from $467 million
in the fourth quarter of 1997. We also reported that net income for the year
ended December 31, 1998 was $94.7 million, or $4.00 per share, compared with net
income of $103.2 million, or $4.31 per share, for the year ended December 31,
1997. Our sales for the year ended December 31, 1998 totaled $1.84 billion
compared with sales of $1.77 billion for the year ended December 31, 1997.
Results for 1998 were reduced by approximately $.90 per share due to economic
conditions in Asia and the General Motors strike. For the fourth quarter of
1998, we announced that Morse TEC's sales increased 19% to $100.6 million;
Powertrain Systems' sales were $139.1 million, 11% below last year's fourth
quarter results due in part to fewer transfer case shipments for Ford trucks;
Automatic Transmissions' sales increased 2% to $107.2 million, excluding sold
product lines; Air/Fluid Systems' sales increased 8% to $89.2 million; and sales
from the European turbocharger business were $53.1 million.
 
PENDING ACQUISITION OF KUHLMAN CORPORATION
 
     On December 17, 1998, we entered into a merger agreement with Kuhlman
Corporation, which provides that Kuhlman will become a wholly owned subsidiary
of Borg-Warner Automotive.
 
     The total value of consideration we will pay in the merger, based on the
number of shares of Kuhlman common stock outstanding on December 31, 1998, is
approximately $677.8 million. Approximately $527.8 million of this amount will
be in cash, with the remaining $150 million in Borg-Warner Automotive common
stock.
 
     Kuhlman is a diversified, industrial manufacturing company that currently
operates in two product segments: industrial products and electrical products.
Through its Schwitzer Group, which includes Kuhlman's industrial products
business, Kuhlman is a leading worldwide manufacturer of proprietary engine
components, including turbochargers, fans and fan drives, fuel tanks,
instrumentation, heating/ventilation/air conditioning systems, and other
products used primarily in commercial transportation products and industrial
equipment. Kuhlman's electrical products businesses include the manufacture of
transformers and other products for electrical utilities and industrial users,
as well as electrical and electronic wire and cable products for use in
consumer, commercial and industrial applications. We intend to sell the
electrical products businesses following the completion of the merger and have
retained Morgan Stanley Dean Witter to facilitate the sale. Kuhlman's products
are sold to over 5,000 domestic and international customers operating in more
than 60 countries worldwide.
 
ACQUISITION OF TURBO SYSTEMS BUSINESS OF AG KUHNLE, KOPP & KAUSCH
 
     Prior to December 10, 1998, we acquired approximately 63% of AG Kuhnle,
Kopp & Kausch, which manufactures turbochargers, compressors and turbines. On
December 10, 1998, we announced that we completed the purchase of 100% of the
turbocharger systems business of AG Kuhnle. Through this European turbocharger
business, we supply turbochargers to European diesel and spark ignition engine
manufacturers for use in passenger cars and commercial vehicles. On February 8,
1999, we reported that our sales from the European turbocharger business were
$182.9 million in 1998. We continue to own approximately 63% of AG Kuhnle, which
continues to manufacture compressors and turbines for use in the energy and
environmental support markets. Our interest in AG Kuhnle is treated as a
business held for sale.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
 
     The following unaudited pro forma consolidated financial statements consist
of an unaudited pro forma consolidated balance sheet as of September 30, 1998,
and unaudited pro forma consolidated statements of operations for the year ended
December 31, 1997 and for the nine-month periods ended September 30, 1998 and
1997. The pro forma statements combine the historical financial statements of
Borg-Warner Automotive and Kuhlman as of and for the periods indicated. The pro
forma financial statements also reflect the following:
 
     -  The merger will be accounted for as a purchase. We will fund the
       transaction by issuing approximately $150 million in Borg-Warner
       Automotive common stock and borrowing the remainder. Subject to the
       provisions of the merger agreement with Kuhlman, each outstanding share
       of Kuhlman common stock will be converted into the right to receive (1)
       $39.00 in cash, without interest, or (2) $39.00 worth of shares of
       Borg-Warner Automotive common stock.
 
     -  We will assume or refinance Kuhlman's existing indebtedness which was
       $98.4 million as of September 30, 1998 and is estimated to be between $80
       million and $90 million at the closing of the merger. In addition, we
       will incur additional indebtedness for the settlement of stock options
       and certain long-term incentive programs and severance programs, which
       are estimated to be approximately $45 million, net of tax benefits. To
       the extent that additional stock options are exercised prior to the
       completion of the merger, the number of shares of Kuhlman common stock
       outstanding will increase and the related settlement cost relating to
       stock options will decrease.
 
     -  Borg-Warner Automotive and Kuhlman will pay anticipated investment
       banking, legal, accounting and regulatory fees and costs related to the
       merger estimated to be $12 million.
 
     We have not completed the analyses necessary to determine the allocation of
purchase price based on the fair values of assets and liabilities acquired and,
therefore, the excess of purchase price over net assets acquired, except for the
amount allocated to the electrical products businesses as discussed below, is
reflected as goodwill in these pro forma financial statements.
 
     We intend to sell Kuhlman's electrical products businesses. In the pro
forma balance sheet, our net investment in the electrical products businesses is
reflected as an asset held for sale in current assets. The investment includes a
portion of the goodwill related to the merger. The amount of goodwill was
allocated based on the relative historical performance of the electrical
products businesses compared with the total Kuhlman business. We cannot be
certain, but we believe that the net investment in the electrical products
businesses is not greater than the amounts that we will receive upon sale of the
businesses. We expect to use proceeds from the sale to repay merger
indebtedness.
 
     The pro forma consolidated financial statements should be read in
conjunction with the Borg-Warner Automotive consolidated financial statements
and the notes thereto incorporated by reference in this prospectus supplement
and Kuhlman historical consolidated financial statements and notes thereto,
which are on file with the SEC. The pro forma consolidated statements are
presented for informational purposes only and do not purport to be indicative of
what the actual results would have been had the merger occurred as described
above for the periods presented. The pro forma consolidated
 
                                       S-6
<PAGE>   7
 
statements of operations should not be considered indicative of the results of
future operations of the merged companies.
 
     The pro forma consolidated balance sheet was prepared assuming the merger
occurred on September 30, 1998, and the pro forma consolidated statements of
operations were prepared assuming that the merger took place on January 1, 1998
and 1997, respectively. In addition to an accrual for merger-related costs noted
above, the pro forma consolidated statements include the following:
 
     -  the effects of amortization of the goodwill related to the merger (which
       is being amortized over a 40-year life),
 
     -  interest expense on borrowings to be incurred to finance the merger, but
       excluding the portion of the interest expense allocated to the electrical
       products businesses,
 
     -  the elimination of expenses related to Kuhlman's corporate headquarters
       which will be closed,
 
     -  exclusion of revenues, costs and expenses for the electrical products
       businesses, and
 
     -  tax effects of all the preceding adjustments.

(1) The electrical products businesses include two businesses of Kuhlman, one of
    which manufactures transformers and the other of which manufactures wire and
    cable. We plan to sell the electrical products businesses after the merger.
    The pro forma consolidated balance sheet reflects the electrical products
    businesses at net carrying value. This carrying value of $250 million
    includes $121 million of the excess purchase price of the merger. Revenues,
    costs and expenses of the electrical products businesses have been deducted
    from the pro forma Borg-Warner Automotive column of the pro forma
    consolidated financial statements. For purposes of the unaudited pro forma
    consolidated statements of operations, a portion of interest expense and
    amortization of goodwill relating to the merger has been allocated to the
    electrical products businesses, and accordingly has been deducted in
    arriving at the pro forma consolidated statement of operations data. The
    goodwill amortization was based upon the goodwill allocated to such
    businesses. Interest expense was allocated assuming the businesses were
    responsible for the interest on $250 million in acquisition indebtedness.
    The following chart shows the amounts of goodwill amortization and interest
    expense allocated to the electrical products businesses for each of the
    periods presented.

     The pro forma consolidated financial statements assume that 2,878,526
     shares of Borg-Warner Automotive common stock will be issued in the merger,
     corresponding to an average Borg-Warner Automotive common stock price of
     $52.11. The number of shares of Borg-Warner Automotive common stock
     actually issued in the merger will be based on the daily average of the
     high and low sales prices of Borg-Warner Automotive common stock price
     during the 20 consecutive trading days immediately preceding the third
     trading date prior to the closing date. The effects on earnings per share
     and number of shares to be issued in the merger if the average Borg-Warner
     Automotive stock price were to equal $40.00 per share, $50.00 per share or
     $60.00 per share are shown in the table below.

     Interest expense on acquisition borrowings has been calculated at rates in
     effect for the periods presented in the pro forma consolidated statements
     of operations. These rates were 6.8% for the year ended December 31, 1997,
     6.4% for the nine months ended September 30, 1998 and 6.8% for the nine
     months ended September 30, 1997.
 
(3) The adjustment to eliminate the Kuhlman corporate headquarters expense
     reflects the cost of operating Kuhlman's executive and administrative
     offices in Savannah, Georgia, which will be closed upon completion of the
     merger. A one-time charge to close the headquarters office is included in
     the aggregate purchase price.
 
(4) The tax effect adjustment accounts for the tax effects of the various other
     adjustments, using a domestic marginal rate, where applicable. Amortization
     of goodwill arising from the merger is not deductible for U.S. income tax
     purposes.

                                USE OF PROCEEDS
 
     We expect to use the net proceeds from the sale of the notes to supply a
portion of the funds needed to complete the Kuhlman merger. The Kuhlman merger,
including refinancing of existing indebtedness and related fees and expenses,
will require the issuance of approximately $150 million of our common stock and
the payment of approximately $650 million in cash. The portion of the cash not
supplied by the sale of the notes will be borrowed under our existing bank
credit facility, which will be amended prior to the completion of the Kuhlman
merger.
 
     Completion of the Kuhlman merger is expected to occur in early March 1999.
If, as expected, the sale of the notes is completed prior to the Kuhlman merger,
the net proceeds from the sale of the notes will be used in part to pay down
short-term indebtedness and the remainder will be invested in short-term,
investment-grade financial instruments pending their use in the merger.
 
     If for any reason the Kuhlman merger is terminated after completion of the
sale of the notes, we intend to use approximately $150 million of the net
proceeds to repay existing debt. The existing debt to be repaid was borrowed
under various agreements with floating interest rates that averaged 5.64% as of
December 31, 1998 and had maturities ranging from one day to one year. The
proceeds from this existing debt were used for general corporate purposes,
including capital expenditures and additions to working capital. The balance of
the net proceeds from the sale of the notes would be used for general corporate
purposes, including acquisitions, capital expenditures and additions to working
capital.

     In the computation of our ratio of earnings to fixed charges, earnings
consist of earnings before income taxes, fixed charges and capitalized interest
amortization expense. Fixed charges consist of interest expense excluding the
benefit of capitalized interest and including one-third of rental expense
(approximate portion representing interest).
 
     In the computation of our pro forma ratio of earnings to fixed charges,
revenues, costs and expenses of the electrical products businesses of Kuhlman
have been deducted from our financial results because we intend to sell such
businesses after the Kuhlman merger. Expenses that we deducted include a portion
of interest expense and a portion of goodwill amortization relating to the
Kuhlman merger. Interest expense was allocated assuming such businesses were
responsible for the interest on $250 million in acquisition indebtedness. The
goodwill amortization was based upon the goodwill allocated to the electrical
products businesses.

Interest will be payable semi-annually on February 15 and August 15 of each
year, beginning August 15, 1999. Interest on the notes will accrue from February
22, 1999, or from the most recent date to which interest has been paid or
provided for. Interest on the notes will be paid to holders of record on the
February 1 or August 1 immediately before the interest payment date. Interest
and principal will be payable in U.S. dollars at the Trustee's New York
corporate trust office, which is located at 14 Wall Street, 8th Floor, New York,
New York 10005. The notes due 2009 will mature on February 15, 2009, and the
notes due 2029 will mature on February 15, 2029. The notes will be issued only
in denominations of $1,000 and integral multiples of $1,000. There will be no
sinking fund payments for the notes.
 
     In the accompanying prospectus, there is a section called "Description of
Debt Securities -- Defeasance and Covenant Defeasance," which describes
provisions on the defeasance and covenant defeasance of securities issued under
the Senior Indenture. These provisions will apply to the notes.
 
RANKING
 
     The notes will be senior unsecured obligations of Borg-Warner Automotive
and will rank equally with all of our other senior unsecured indebtedness. On a
pro forma basis as of September 30, 1998, after giving effect to the Kuhlman
merger and the offering of the notes, we would have $484.5 million of other
outstanding senior indebtedness (of which $4.2 million would have been secured
indebtedness) not including the debt of our subsidiaries. Because we are a
holding company, the notes effectively will rank junior to all liabilities of
our subsidiaries. As of September 30, 1998, total liabilities (other than
intercompany liabilities) of our subsidiaries were approximately $433.8 million
and debt of our subsidiaries was approximately $70.4 million.
 
     We may, without the consent of the noteholders, issue additional notes
having the same ranking and the same interest rate, maturity and other terms as
the notes due 2009 or the notes due 2029 offered by this prospectus supplement.
Any such additional notes will be a part of the series having the same terms as
the notes.
 
OPTIONAL REDEMPTION
 
     Each of the notes due 2009 and the notes due 2029 may be redeemed in whole
at any time or in part from time to time, at our option, at a redemption price
equal to the greater of (1) 100% of the principal amount of the applicable
series of notes, and (2) the sum of the present values of the remaining
scheduled payments of principal and interest on the applicable series of notes
discounted to the date of redemption on a semi-annual basis
 
                                      S-17
<PAGE>   18
 
(assuming a 360-day year consisting of twelve 30-day months) at the applicable
Treasury Rate plus 15 basis points for the notes due 2009, or the applicable
Treasury Rate plus 25 basis points for the notes due 2029, plus, in either case,
accrued and unpaid interest on the principal amount being redeemed to the
redemption date.
 
     "Treasury Rate" means, with respect to any redemption date, (1) the yield,
under the heading which represents the average for the immediately preceding
week, appearing in the most recently published statistical release designated
"H.15(519)" or any successor publication which is published weekly by the Board
of Governors of the Federal Reserve System and which establishes yields on
actively traded United States Treasury securities adjusted to constant maturity
under the caption "Treasury Constant Maturities," for the maturity corresponding
to the Comparable Treasury Issue (if no maturity is within three months before
or after the Remaining Life, yields for the two published maturities most
closely corresponding to the Comparable Treasury Issue will be determined and
the Treasury Rate will be interpolated or extrapolated from such yields on a
straight line basis, rounding to the nearest month) or (2) if such release (or
any successor release) is not published during the week preceding the
calculation date or does not contain such yields, the rate per annum equal to
the semi-annual equivalent yield-to-maturity of the Comparable Treasury Issue,
calculated using a price for the Comparable Treasury Issue (expressed as a
percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date. The Treasury Rate will be calculated on the third Business
Day preceding the redemption date.
 
     "Business Day" means any calendar day that is not a Saturday, Sunday or
legal holiday in New York, New York and on which commercial banks are open for
business in New York, New York.
 
     "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term ("Remaining Life") of the notes to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of such notes.
 
     "Independent Investment Banker" means either Merrill Lynch, Pierce, Fenner
& Smith Incorporated or Morgan Stanley & Co. Incorporated, or, if both firms are
unwilling or unable to select the Comparable Treasury Issue, an independent
investment banking institution of national standing appointed by the Trustee
after consultation with Borg-Warner Automotive.
 
     "Comparable Treasury Price" means (1) the average of five Reference
Treasury Dealer Quotations for such redemption date, after excluding the highest
and lowest Reference Treasury Dealer Quotations, or (2) if the Independent
Investment Banker obtains fewer than five such Reference Treasury Dealer
Quotations, the average of all such quotations.
 
     "Reference Treasury Dealer" means (1) Merrill Lynch, Pierce Fenner & Smith
Incorporated and Morgan Stanley & Co. Incorporated and their respective
successors, provided, however, that if any of the foregoing shall cease to be a
primary U.S. Government securities dealer in New York City (a "Primary Treasury
Dealer"), we will substitute for such underwriter another Primary Treasury
Dealer and (2) any other Primary Treasury Dealer selected by the Independent
Investment Banker after consultation with Borg-Warner Automotive.
 
                                      S-18
<PAGE>   19
 
     "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Independent Investment Banker, of the bid and asked prices for the
Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Independent Investment Banker at 5:00
p.m., New York City time, on the third Business Day preceding such redemption
date.
 
     Holders of notes to be redeemed will receive notice thereof by first-class
mail at least 30 and not more than 60 days prior to the date fixed for
redemption. If fewer than all of the notes are to be redeemed, the Trustee will
select, not more than 60 days prior to the redemption date, the particular notes
or portions thereof for redemption from the outstanding not previously called by
such method as the Trustee deems fair and appropriate.

                 CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS
 
     For a summary of the material U.S. Federal income tax consequences of an
investment in the notes, see "Certain U.S. Federal Income Tax Consequences"
beginning on page 24 in the accompanying prospectus.
 
RECENT DEVELOPMENTS
 
     President Clinton's fiscal year 2000 budget plan contains a proposal which,
if enacted, would require U.S. Holders (as defined in the accompanying
prospectus) who use the accrual method of accounting to include market discount
in income as it accrues. The proposal would affect any debt instrument acquired
on or after the date on which the proposal is enacted.
 
     The market discount rules currently in effect are described under the
heading "U.S. Holders -- Market Discount" in the section called "Certain U.S.
Federal Income Tax Considerations" in the accompanying prospectus. Under current
rules, unless the U.S. Holder elects otherwise, any gain on the maturity or
disposition of a Market Discount Debt Security (as defined in the accompanying
prospectus) will be treated as ordinary income to the extent that it does not
exceed the amount of accrued market discount on the security. If the U.S. Holder
makes an election to take market discount into income as it accrues over the
life of the security, the election will apply to all debt instruments with
market discount that the electing U.S. Holder acquires on or after the first day
of the first taxable year for which the election is made. Thus, under current
rules, if a U.S. Holder that is an accrual method taxpayer does not elect to
include market discount in income as it accrues, such holder is not required to
do so for any Market Discount Debt Security which the holder owns.
 
     Under the budget proposal, an accrual method U.S. Holder would be required
to include market discount in income as it accrues for all Market Discount Debt
Securities which such holder acquires on or after the date of enactment.
 
     Also, under current rules, market discount generally accrues on a
straight-line basis, unless the holder makes an election to accrue market
discount on a constant-yield basis.
 
     Under the budget proposal, the holder's yield for purposes of calculating
and accruing market discount would be limited to the larger of (1) the
applicable Federal rate at the time the holder acquired the debt instrument plus
five percentage points and (2) the original yield-to-maturity of the debt
instrument plus five percentage points.
 
     THIS SUMMARY OF THE BUDGET PROPOSAL CONCERNING MARKET DISCOUNT IS FOR
GENERAL INFORMATION ONLY. YOU ARE URGED TO CONSULT YOUR PERSONAL TAX ADVISORS
CONCERNING THE STATUS OF THE PROPOSAL AND THE PARTICULAR CONSEQUENCES TO YOU IF
IT IS ENACTED.

</TABLE>
 
     The underwriters have advised us that they propose initially to offer the
notes 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 .40% and .50% of the principal amounts of the notes
due 2009 and the notes due 2029, respectively. The underwriters may allow, and
such dealers may reallow, a discount not in excess of .25% of the principal
amount of the notes to certain other dealers. After the initial public offering,
the underwriters may change the public offering price, concession and discount.
 
     The notes due 2009 and the notes due 2029 are new issues of securities, and
there is currently no established trading market for the notes. In addition, we
do not intend to apply for the notes to be listed on any securities exchange or
to arrange for the notes to be quoted on any quotation system. The underwriters
have advised us that they intend to make a market in the notes, but they are not
obligated to do so. The underwriters may discontinue any market making in the
notes at any time without notice. We can give you no assurance as to the
liquidity of, or any trading market for, the notes.
 
     In connection with this offering, the underwriters are permitted to engage
in certain transactions that stabilize the price of the notes. Such transactions
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of the notes. If the underwriters create a short position in the notes
in connection with this offering, i.e., if they sell a greater aggregate
principal amount of notes than is set forth on the cover of this prospectus
supplement, the underwriters may reduce that short position by purchasing notes
in the open market. In general, purchases of a security for the purpose of
stabilization or to reduce a short position could cause the price of the
security to be higher than it might be in the absence of such purchases.
 
     Neither we nor any underwriter makes any representation or prediction as to
the direction or magnitude of any effect that the transactions described above
may have on the price of the notes. In addition, neither we nor any underwriter
makes any representation
 
                                      S-21
<PAGE>   22
 
that the underwriters will engage in such transactions or that such
transactions, once commenced, will not be discontinued without notice.
 
     We have agreed to indemnify the underwriters against, or to contribute to
payments that the underwriters may be required to make in respect of, certain
liabilities, including liabilities under the Securities Act of 1933.
 
     In the ordinary course of their respective businesses, the underwriters or
their affiliates from time to time provide commercial and investment banking and
other financial services to Borg-Warner Automotive. The Chase Manhattan Bank, an
affiliate of Chase Securities Inc., is the administrative agent and a lender
under our credit facility and NationsBank, an affiliate of NationsBanc
Montgomery Securities LLC, and The First National Bank of Chicago, an affiliate
of First Chicago Capital Markets, are lenders under our credit facility and will
receive their proportional share of the repayment of amounts outstanding, if
any, under the credit facility if a portion of the proceeds of the offering is
used to repay indebtedness outstanding under the agreement. Because The Chase
Manhattan Bank, NationsBank and The First National Bank of Chicago may receive
more than 10% of the proceeds from the sale of the notes, not including
underwriting compensation, this offering is being conducted in compliance with
the National Association of Securities Dealers Conduct Rule 2710(c)(8). See "Use
of Proceeds." Morgan Stanley Dean Witter is acting as financial advisor to
Borg-Warner Automotive in connection with the Kuhlman merger and the proposed
sale of Kuhlman's electrical products business. Alexis P. Michas, a member of
our board of directors, is a director of an affiliate of Merrill Lynch, Pierce,
Fenner & Smith Incorporated.
 
     We estimate that the total expense of the offering, excluding underwriting
discounts and commissions, will be approximately $570,000.

                                  RISK FACTORS
 
     You should carefully consider the following factors, as well as the other
information in this prospectus and the information in the documents incorporated
by reference, before you make any decision to invest in the debt securities
described in this prospectus and the accompanying prospectus supplement.
 
HOLDING COMPANY STRUCTURE; THE DEBT SECURITIES RANK JUNIOR TO THE OBLIGATIONS OF
OUR SUBSIDIARIES
 
     We are a holding company with no material assets other than the stock of
our subsidiaries. Our subsidiaries conduct substantially all of our operations
and own substantially all of our assets. Consequently, our operating cash flow
and our ability to make principal and interest payments on our outstanding
indebtedness depends upon the cash flow of our subsidiaries and the payment of
funds by our subsidiaries to us in the form of loans, dividends or otherwise.
Our subsidiaries are not obligated to make funds available to us for payment on
the debt securities or otherwise.
 
     The debt securities effectively will rank junior to all liabilities of our
subsidiaries. In the event of a bankruptcy, liquidation or dissolution of any of
our subsidiaries, and following payment of these liabilities, our subsidiaries
may not have sufficient assets remaining to make payments to us as a shareholder
or otherwise.
 
     As of September 30, 1998, total liabilities (other than intercompany
liabilities) of our subsidiaries were approximately $433.8 million and debt of
our subsidiaries was approximately $70.4 million.
 
AUTOMOTIVE INDUSTRY CYCLICALITY
 
     Our principal operations are directly related to domestic and foreign
automotive production. Automotive production and sales are cyclical and depend
upon general economic conditions and other factors. As compared to 1997, we
believe automotive production in 1998 declined slightly in North America,
increased moderately in Europe, and declined in Asia. Any significant reduction
in automotive production would have a material adverse effect on our sales to
original equipment manufacturers and our financial position and operating
results.
 
EFFECT OF ASIAN ECONOMIC CONDITIONS
 
     During 1997, approximately 21% of our sales, including sales from
unconsolidated joint ventures, were in Asia. We continue to be adversely
affected by the weakness in Asia's economies. Sales of vehicles with our
higher-end content in automatic transmissions and four-wheel drive are
particularly susceptible to weak economic conditions. Although we believe that
our presence in Asian markets is critical to our long-term success, we cannot
assure you that economic conditions in Asia will improve in the future and that
we will not continue to be adversely affected by these economic conditions.
 
DEPENDENCE ON SPORT UTILITY AND LIGHT TRUCK MARKET SEGMENTS
 
     Some of our products are currently used exclusively in sport utility
vehicles and light trucks. Any significant reduction in production in this
market segment or loss of business in this market segment would have a material
adverse effect on our sales to original equipment manufacturers and our
financial position and operating results. For example, our 1998 first and second
quarter results were adversely affected by the loss to a competitor of
 
                                        5
<PAGE>   28
 
a four-wheel drive application for the Ford F-250 truck and the Ford F-350
truck, a 37% reduction in four-wheel drive transfer case shipments for the Ford
F-150 truck, and a decline in four-wheel drive transfer case shipments to
SsangYong in Korea, which became a unit of Daewoo Motor Company in 1998.
 
COMPETITION WITH OTHER AUTOMOTIVE COMPONENT MANUFACTURERS
 
     We compete worldwide with a number of other manufacturers and distributors
that produce and sell products similar to ours. Price, quality and technological
innovation are the primary elements of competition. Our competitors include
vertically integrated units of our major original equipment manufacturer
customers, as well as a large number of independent domestic and international
suppliers. We are not as large as a number of these companies and do not have as
many financial or other resources. Increased competition could adversely affect
our businesses.
 
INCREASE IN COMPETITION FROM INTERNATIONAL SUPPLIERS
 
     The competitive environment has changed dramatically over the past few
years as our traditional United States original equipment manufacturer
customers, faced with intense international competition, have expanded their
worldwide sourcing of components. As a result, we have experienced competition
from suppliers in other parts of the world that enjoy economic advantages such
as lower labor costs, lower health care costs, and, in some cases, export and/or
raw materials subsidies.
 
PRICING CONDITIONS
 
     There is substantial and continuing pressure on the original equipment
manufacturers to reduce costs, including costs of products we supply. Although
original equipment manufacturers have indicated that they will continue to rely
on outside suppliers, a number of our major original equipment manufacturers
customers manufacture products for their own use that directly compete with our
products. These original equipment manufacturers could elect to manufacture such
products for their own uses in place of the products we currently supply. We
believe that our ability to develop proprietary new products and to control our
costs will allow us to remain competitive. However, we cannot assure you that we
will be able to improve or maintain our gross margins on product sales to
original equipment manufacturers or that the recent trend by original equipment
manufacturers towards increased outsourcing will continue.
 
     Annual price reductions to original equipment manufacturer customers appear
to have become a permanent feature of our business environment. In 1997, we
granted $18 million worth of price reductions. To maintain our profit margins,
we seek price reductions from our suppliers, improve production processes to
increase manufacturing efficiency, update product designs to reduce costs and
develop new products whose benefits support increased pricing. Our ability to
pass through increased raw material costs to our original equipment manufacturer
customers is also limited, with cost recovery less than 100% and often on a
delayed basis. We cannot assure you that we will be able to reduce costs in an
amount equal to annual price reductions and the increase in raw material costs.
 
RELIANCE ON MAJOR CUSTOMERS
 
     Our worldwide sales in 1997 to Ford, GM and Chrysler (now a part of
DaimlerChrysler) constituted approximately 43%, 20% and 10%, respectively, of
our 1997 consolidated sales. The corresponding percentages for 1996 were 42%,
21% and 9%. No
 
                                        6
<PAGE>   29
 
other customer accounted for more than 10% of our consolidated sales in either
1997 or 1996. Our 1997 consolidated sales do not include the approximately $354
million of sales made by our unconsolidated joint ventures. If sales from
unconsolidated joint ventures were included in 1997 consolidated sales, our
worldwide sales to Toyota Motor Corporation and its affiliates would be
approximately 7% of consolidated sales.
 
     Although we have had long-standing relationships with each of Ford, GM,
Chrysler and Toyota and have sold a wide variety of products to various
divisions of each company globally, the loss of any significant portion of our
sales to any of these customers would have a material adverse effect on our
financial position and operating results.
 
DEPENDENCE OF OUR LARGE CUSTOMERS ON THE UNITED AUTOMOBILE, AEROSPACE AND
AGRICULTURAL IMPLEMENT WORKERS OF AMERICA
 
     All three of our primary North American customers, GM, Ford and Chrysler,
have major union contracts with the United Automobile, Aerospace and
Agricultural Implement Workers of America. Because of the United States original
equipment manufacturers' dependence on a single union, we are affected by labor
difficulties and work stoppages at original equipment manufacturers' facilities.
For example, we lost approximately $25 million in revenue as a result of the
1998 54-day strike by the United Automobile, Aerospace and Agricultural
Implement Workers of America at GM.
 
LABOR RELATIONS
 
     Approximately 37% of our domestic hourly employees are unionized. Our two
most significant domestic collective bargaining agreements are for our Muncie,
Indiana plant and our Ithaca, New York plant. The Muncie agreement was renewed
in March 1998 and the Ithaca agreement was renewed in October 1998. While we
believe that our relations with our employees are good, a prolonged dispute with
our employees could have a material adverse effect on our financial position or
operating results.
 
UNFUNDED PENSION OBLIGATIONS
 
     We have substantial unfunded pension obligations. On December 31, 1997, the
present values of our projected benefit obligations and accumulated benefit
obligations of underfunded plans were $234.4 million and $231.1 million,
respectively. The fair value of our pension plan assets with respect to such
plans as of December 31, 1997 was $177.5 million. The resulting unfunded portion
of $56.9 million at December 31, 1997 compared favorably with an unfunded
portion of $69.8 million at December 31, 1996 (based on our projected benefit
obligations on the respective dates). This decrease was due in part to an
increase in the value of investments related to these obligations. Of the 1997
unfunded portion, approximately $25.3 million related to the accumulated pension
obligations for our German subsidiaries, which do not require funding. Our
long-term objective is to fund our entire pension obligation with funds that are
generated from operations, but we cannot assure you that this will actually
occur.
 
COMPLIANCE WITH ENVIRONMENTAL REGULATIONS
 
     Our operations are subject to laws governing, among other things, emissions
to air, discharges to waters and the generation, handling, storage,
transportation, treatment and disposal of waste and other materials. We believe
that our business, operations and facilities have been and are being operated in
compliance in all material respects with applicable environmental and health and
safety laws. However, the operation of automotive
 
                                        7
<PAGE>   30
 
parts manufacturing plants entails risks in these areas and we cannot assure you
that we will not incur material costs or liabilities. In addition, potentially
significant expenditures could be required in order to comply with evolving
environmental and health and safety laws that may be adopted in the future.
 
     We believe that the overall impact of compliance with regulations and
legislation protecting the environment will not have a material adverse effect
on our future financial position or operating results, but we cannot assure you
that this will be the case. Capital expenditures and expenses in 1998
attributable to compliance with environmental laws were not material.
 
POTENTIAL LIABILITY UNDER ENVIRONMENTAL REGULATIONS
 
     We and certain of our current and former direct and indirect corporate
predecessors, subsidiaries and divisions have been identified by the United
States Environmental Protection Agency and certain state environmental agencies
and private parties as potentially responsible parties at 28 hazardous waste
disposal sites under the Comprehensive Environmental Response, Compensation and
Liability Act and equivalent state laws. As a result, we may be liable for the
cost of clean-up and other remedial activities at these sites.
 
     Based on information available to us which, in most cases, includes:
 
     -  an estimate of allocation of liability among potentially responsible
        parties;
 
     -  the probability that other potentially responsible parties, many of whom
        are large, solvent public companies, will fully pay the costs
        apportioned to them;
 
     -  currently available information from potentially responsible parties
        and/or federal or state environmental agencies concerning the scope of
        contamination and estimated remediation costs;
 
     -  estimated legal fees; and
 
     -  other factors,
 
we have established a reserve in our financial statements for indicated
environmental liabilities with a balance of approximately $5.9 million at
September 30, 1998. We currently expect this amount to be expended over the next
three to five years.
 
     We believe that none of these matters, individually or in the aggregate,
will have a material adverse effect on our future financial position or
operating results, either because estimates of the maximum potential liability
at a site are not large or because liability will be shared with other
potentially responsible parties. However, we cannot assure you of the ultimate
outcome.
 
YEAR 2000
 
     We are in the process of upgrading certain aspects of our operations to
ensure that business systems do not fail to function either when the Year 2000
arrives or at other date intervals. We have completed an inventory of key
systems and equipment with potential Year 2000 issues in the areas of business
operating systems, manufacturing operations, operating infrastructure, customers
and suppliers. This included an identification of mission critical systems, an
assessment of the readiness of our applications for Year 2000 and the corrective
action needed, if any.
 
                                        8
<PAGE>   31
 
     We also are participating in the process coordinated by the Automotive
Industries Action Group, a group sponsored by the major U.S. automakers. The
process consists of ongoing surveys to measure a company's state of readiness
and its progress on the assessment and remediation stages of its program. The
survey results are used to monitor progress against remediation action plans.
 
     Our program to become Year 2000 compliant is being operated on an
enterprise-wide basis. A coordinator has been assigned overall administrative
responsibility; however, each operating unit is responsible for compliance at
its location. As of the end of June 1998, inventories and assessments had been
completed at substantially all of our locations. Corrective action is underway.
We believe that the majority of items identified as non-compliant would not
significantly interfere with our operations if not updated. In addition, our
exposure to an enterprise-wide failure is less likely because of the relative
autonomy of our operating units. We are operating on a schedule to have
substantially all non-compliant items remedied by mid-1999. We are also seeking
confirmation from key suppliers and other third parties that their systems and
applications that affect us will be Year 2000 compliant by mid-1999.
 
     Concurrent with the Year 2000 effort, we are in the process of upgrading
certain of our business operating systems at a number of our units to improve
both business operations and control. We now require any system acquired to be
certified as Year 2000 compliant.
 
     We believe that we will spend approximately $11.5 million for new systems,
to upgrade systems and equipment and for other efforts to ensure compliance with
Year 2000 between 1997 and 1999. These costs will be paid for with cash from our
operations. The bulk of such spending will provide for system improvements and
enhancements including compliance with Year 2000. Through September 30, 1998, we
have spent approximately $6 million. Spending solely related to Year 2000
compliance is not expected to be material to either our financial position or
results of operations for any given year.
 
     As with any program to upgrade business systems, there are risks that
programs will not be completed on schedule and that programs will not accomplish
all that they were supposed to accomplish. The chance of this happening
throughout our company is remote. Moreover, for individual failures to upgrade
timely and effectively, the impact would most likely be a reduced level of
quality control for operations and a substantial increase in the amount of
manual intervention in areas such as material planning and inventory control,
statistical process control, and financial and operational recordkeeping.
 
     We do not have in place substantial contingency plans because we believe
that our efforts will be successful. We have, however, identified specific
procedures required to keep our operations functioning in the event of delays or
machine failures. As we mentioned above, we have identified key suppliers and
requested confirmation as to their Year 2000 compliance. We are currently in the
process of verifying supplier responses, including supplier audits and other
action as appropriate. We are also considering the availability of alternative
supply sources in the event that they are needed.
 
     We cannot assure you that the corrective actions we are implementing will
prevent dating systems problems or that the cost of doing so will not be
material. In addition, disruptions with respect to the computer systems of
vendors or customers, including both information technology and non-information
technology systems could impair our ability to obtain necessary materials or
products to sell to or serve our customers. Disruptions of our computer systems
or the computer systems of our vendors or customers, as well as the cost
 
                                        9
<PAGE>   32
 
of avoiding such disruption, could have a material adverse effect upon our
financial position or operating results.
 
EURO CONVERSION
 
     On January 1, 1999, 11 of the 15 member countries of the European Union
established fixed conversion rates between their existing currencies and the
euro. The participating countries adopted the euro as their common legal
currency on that date. We have begun consideration of the effects of the euro
conversion on our operations, but we are currently unsure of the potential
impact that the euro conversion will have on our financial position or operating
results. Because of the nature of our business and customers, the effect is not
expected to be material.
 
                                USE OF PROCEEDS
 
     Unless otherwise set forth in the applicable prospectus supplement, the net
proceeds from the sale of the debt securities will be used for general corporate
purposes, including the repayment of existing indebtedness, additions to working
capital, capital expenditures and acquisitions. Any specific allocation of the
net proceeds of an offering of debt securities to a specific purpose will be
described in the related prospectus supplement. We anticipate that we will raise
additional funds from time to time through equity or debt financings to repay
outstanding indebtedness and to finance our businesses.
 
                       RATIO OF EARNINGS TO FIXED CHARGES
 
     Our ratio of earnings to fixed charges for the periods indicated below was
as follows:

     In the computation of our ratio of earnings to fixed charges, earnings
consist of earnings before income taxes, fixed charges and capitalized interest
amortization expense. Fixed charges consist of interest expense excluding the
benefit of capitalized interest and including one-third of rental expense
(approximate portion representing interest).

                         DESCRIPTION OF DEBT SECURITIES
 
     The following descriptions of the terms of the debt securities set forth
certain general terms and provisions of the debt securities. The particular
terms of the debt securities offered by any prospectus supplement and the
extent, if any, to which such general provisions may apply to the debt
securities so offered will be described in the prospectus supplement relating to
such offered debt securities. To the extent that any prospectus supplement is
inconsistent with any provision in this summary, the information contained in
such prospectus supplement will control.
 
     The debt securities that will be our senior debt will be issued under an
Indenture (the "SENIOR DEBT INDENTURE") to be entered into between Borg-Warner
Automotive and The First National Bank of Chicago (the "SENIOR TRUSTEE"). The
debt securities that will be our subordinated debt ("SUBORDINATED DEBT
SECURITIES") will be issued under an Indenture (the "SUBORDINATED DEBT
INDENTURE" and, collectively with the Senior Debt Indenture, the "INDENTURES"),
to be entered into between Borg-Warner Automotive and a trustee to be determined
(the "SUBORDINATED TRUSTEE"). The forms of the Indentures and the debt
securities have been filed, or will be filed by amendment, as exhibits to the
registration statement and you should read them for the provisions that may be
important to you. The Indentures are subject to and governed by the Trust
Indenture Act of 1939, as amended (the "TIA"). We have summarized certain
provisions of the debt securities and the Indentures below. The summary is not
complete and is subject to, and qualified in its entirety by reference to, the
Indentures and the debt securities. Capitalized terms used in the summary have
the meanings set forth in the applicable Indenture unless otherwise defined
herein.
 
GENERAL
 
     The debt securities will be our unsecured senior or subordinated
obligations.
 
     The Indentures do not limit the amount of debt securities that we may issue
thereunder and provide that we may issue debt securities under the Indentures
from time to time in one or more series.
 
     Reference is made to the prospectus supplement for the following terms of
and information relating to the offered debt securities (to the extent such
terms are applicable to such debt securities):
 
     -  classification as senior or subordinated debt securities;
 
     -  the specific designation, aggregate principal amount, purchase price and
        denomination of the offered debt securities;
 
     -  the currency or units based on or relating to currencies in which such
        debt securities are denominated and/or in which principal (and premium,
        if any) and/or any interest will or may be payable;
 
     -  any date of maturity;
 
     -  the method by which amounts payable in respect of principal, premium (if
        any) or interest on, or upon the redemption of, such debt securities may
        be calculated, and any currencies or indices, or value, rate or price,
        relevant to such calculation;
 
     -  interest rate or rates (or the method by which such rate will be
        determined), if any;
 
                                       11
<PAGE>   34
 
     -  the date or dates on which any such interest will be payable;
 
     -  the place or places where the principal of and interest, if any, on the
        offered debt securities will be payable;
 
     -  any redemption, repayment or sinking fund provisions for the offered
        debt securities;
 
     -  whether the offered debt securities will be issuable in registered form
        or bearer form ("BEARER SECURITIES") or both and, if Bearer Securities
        are issuable, any restrictions applicable to the exchange of one form
        for another and to the offer, sale and delivery of Bearer Securities;
 
     -  any applicable United States federal income tax consequences not
        described in this prospectus, including whether and under what
        circumstances we will pay additional amounts on offered debt securities
        held by a person who is not a U.S. person (as defined in the prospectus
        supplement) in respect of any tax, assessment or governmental charge
        withheld or deducted and, if so, whether we will have the option to
        redeem such debt securities rather than pay such additional amounts;
 
     -  the anticipated market for the offered debt securities; and
 
     -  any other specific terms of the offered debt securities, including any
        additional or different events of default, remedies or covenants
        provided for with respect to such debt securities, and any terms which
        may be required by or advisable under applicable laws or regulations.
 
     Debt securities may be presented for exchange and registered debt
securities may be presented for transfer in the manner, at the places and
subject to the restrictions set forth in the debt securities and the prospectus
supplement. Such services will be provided without charge, other than any tax or
other governmental charge payable in connection therewith, but subject to the
limitations provided in the applicable Indenture. Bearer Securities and the
coupons, if any, attached to such Bearer Securities will be transferable by
delivery.
 
     Debt securities may bear interest at a fixed rate or a floating rate. Debt
securities bearing no interest or interest at a rate that at the time of
issuance is below the prevailing market rate may be sold at a discount below
their stated principal amount. Special United States federal income tax
considerations applicable to any such discounted debt securities or to certain
debt securities issued at par which are treated as having been issued at a
discount for United States federal income tax purposes will be described in the
relevant prospectus supplement to the extent not described in this prospectus.
See "Certain U.S. Federal Income Tax Considerations."
 
     We may issue debt securities from time to time with payment terms which are
calculated by reference to the value or price of one or more currencies or
indices. Holders of such debt securities may receive a payment of the principal
amount on any principal payment date, or a payment of interest on any interest
payment date, that is greater than or less than the amount of principal or
interest otherwise payable on such dates, or a redemption amount on any
redemption date that is greater than or less than the principal amount of such
debt securities, depending upon the value or price on such dates of the
applicable currency or index. Information for determining the amount of
principal, premium (if any), interest or redemption amounts payable on any date,
the currencies, commodities or indices to which the amount payable on such date
is linked and certain additional tax considerations will be set forth in the
relevant prospectus supplement.

     We are a holding company with no material assets other than the stock of
our subsidiaries. Our subsidiaries conduct substantially all of our operations
and own substantially all of our assets. Consequently, our operating cash flow
and our ability to make principal and interest payments on our outstanding
indebtedness depends upon the cash flow of our subsidiaries and the payment of
funds by our subsidiaries to us in the form of loans, dividends or otherwise.
Our subsidiaries are not obligated to make funds available to us for payment on
the debt securities or otherwise.
 
     The debt securities effectively will rank junior to all liabilities of our
subsidiaries. In the event of a bankruptcy, liquidation or dissolution of any of
our subsidiaries, and following payment of these liabilities, our subsidiaries
may not have sufficient assets remaining to make payments to us as a shareholder
or otherwise.
 
CERTAIN DEFINITIONS
 
     "ATTRIBUTABLE INDEBTEDNESS" means, with respect to any Sale/Leaseback
Transaction as of any particular time, the present value (discounted at the rate
of interest implicit in the terms of the lease) of the obligations of the lessee
under such lease for net rental payments during the remaining term of the lease
(including any period for which such lease has been extended). "NET RENTAL
PAYMENTS" under any lease for any period means the sum of the rental and other

     "CONSOLIDATED NET TANGIBLE ASSETS" means the total amount of assets (less
applicable reserves and other properly deductible items) after deducting
therefrom (1) all current liabilities (excluding any current liabilities which
are by their terms extendible or renewable at the option of the obligor thereon

being computed), (2) all goodwill, trade names, trademarks, patents, unamortized
debt discount and expense and other like intangibles and (3) appropriate
adjustments on account of minority interests of other Persons holding stock of
our Subsidiaries, all as set forth on our most recent balance sheet (but, in any
event, as of a date within 150 days of the date of determination) and computed
in accordance with generally accepted accounting principles.
 
     "CONSOLIDATED NET WORTH" means the amount of total stockholders' equity
shown in our most recent consolidated statement of financial position.

that would in accordance with generally accepted accounting principles be
classified as current liabilities.
 
     "NON-RECOURSE INDEBTEDNESS" means our indebtedness or the indebtedness of
any of our Subsidiaries in respect of which the recourse of the holder of such
indebtedness, whether direct or indirect and whether contingent or otherwise, is
effectively limited to specified assets, and with respect to which neither we
nor any of our Subsidiaries provide any credit support.
 
     "PERSON" means any individual, corporation, partnership, joint venture,
association, joint-stock company, trust, unincorporated organization or
government or any agency or political subdivision thereof.
 
                                       13
<PAGE>   36
 
     "PRINCIPAL PROPERTY" means any manufacturing plant or warehouse, together
with the land upon which it is erected and fixtures comprising a part thereof,
that we own or that is owned by one of our Subsidiaries which constitutes a 
"significant subsidiary" as defined in Rule 1-02 of Regulation S-X of the
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), and is located
in the United States, the gross book value (without deduction of any reserve for
depreciation) of which on the date as of which the determination is being made
is an amount which exceeds 1% of Consolidated Net Tangible Assets, other than
any such manufacturing plant or warehouse or any portion thereof (together with
the land upon which it is erected and fixtures comprising a part thereof) (1)
which is financed by Industrial Development Bonds or (2) which, in the opinion
of the Board of Directors, is not of material importance to our total business
conducted and the total business conducted by our Subsidiaries, taken as a
whole.
 
     "SALE/LEASEBACK TRANSACTION" means any arrangement with any Person pursuant
to which we or any of our Subsidiaries lease for a period of more than three
years, any real or personal property, which property we have or such Subsidiary
has sold or transferred or will sell or transfer to such Person in contemplation
of such leasing.
 
     "SUBSIDIARY" of a Person means (1) any corporation more than 50% of the
outstanding securities having ordinary voting power of which is owned, directly
or indirectly, by such Person or by one or more of its Subsidiaries, or by such
Person and one or more of its Subsidiaries, or (2) any partnership or similar
business organization more than 50% of the ownership interests having ordinary
voting power of which shall at the time be so owned. For the purposes of this
definition, "SECURITIES HAVING ORDINARY VOTING POWER" means securities or other
equity interests that ordinarily have voting power for the election of
directors, or persons having management power with respect to the Person,
whether at all times or only so long as no senior class of securities has such
voting power by reason of any contingency.
 
SENIOR DEBT
 
     The debt securities and coupons, if any, appertaining thereto that will
constitute part of our senior debt will be issued under the Senior Debt
Indenture and will rank pari passu with all of our other unsecured and
unsubordinated debt.
 
     Limitation on Liens
 
     The Senior Debt Indenture provides that we will not, and will not permit
any of our Subsidiaries to, issue, assume or guarantee any indebtedness for
money borrowed ("DEBT") if such Debt is secured by a mortgage, pledge, security
interest or lien (a "MORTGAGE" or "MORTGAGES") upon any of our Principal
Properties or of any of our Subsidiaries' Principal Properties or upon any
shares of stock or other stock or other equity interest or indebtedness of any
of our Subsidiaries (whether such property, shares of stock or other equity
interest or indebtedness is now owned or hereafter acquired) which owns any
Principal Property, without in any such case effectively providing that the debt
securities shall be secured equally and ratably with (or prior to) such Debt;
provided, however, that the foregoing restrictions shall not apply to:
 
     -  mortgages existing on the date the debt securities are originally issued
        or mortgages provided for under the terms of agreements existing on such
        date;
 
     -  mortgages on Current Assets securing Current Liabilities;
 
                                       14
<PAGE>   37
 
     -  mortgages on any property we or any of our Subsidiaries acquire,
        construct, alter or improve after the date of the Indenture that are
        created or assumed contemporaneously with or within one year after such
        acquisition (or, in the case of property constructed, altered or
        improved, after the completion and commencement of commercial operation
        of such property, whichever is later) to secure or provide for the
        payment of the purchase price or cost of such property, provided that in
        the case of any such construction, alteration or improvement the
        mortgages shall not apply to any property we or any of our Subsidiaries
        theretofore owned, other than (1) the property so altered or improved
        and (2) any theretofore unimproved real property on which the property
        so constructed or altered, or the improvement, is located;
 
     -  existing mortgages on property we or any of our Subsidiaries acquire
        (including mortgages on any property acquired from a Person that is
        consolidated with or merged with or into us or any of our Subsidiaries)
        or mortgages outstanding at the time any Person becomes one of our
        Subsidiaries that are not incurred in connection with such entity
        becoming one of our Subsidiaries;
 
     -  mortgages in our or any of our Subsidiaries' favor;
 
     -  mortgages on any property (1) in favor of domestic or foreign
        governmental bodies to secure partial, progress, advance or other
        payments pursuant to any contract or statute, (2) securing indebtedness
        incurred to finance all or any part of the purchase price or cost of
        constructing, installing or improving the property subject to such
        mortgages including mortgages to secure Debt of the pollution control or
        industrial revenue bond type, or (3) securing indebtedness issued or
        guaranteed by the United States, any State, any foreign country or any
        department, agency, instrumentality or political subdivision of any such
        jurisdiction; and
 
     -  any extension, renewal or replacement (or successive extensions,
        renewals or replacements), in whole or in part, of any mortgage referred
        to in the foregoing bullet points; provided, however, that the principal
        amount of Debt secured thereby shall not exceed the principal amount of
        Debt so secured at the time of such extension, renewal or replacement,
        together with the reasonable costs related to such extension, renewal or
        replacement, and that such extension, renewal or replacement shall be
        limited to all or a part of the property that secured the mortgage so
        extended, renewed or replaced (plus improvements on such property).
 
     Notwithstanding the foregoing, we and any of our Subsidiaries may, without
securing the debt securities, issue, assume or guarantee secured Debt (that
would otherwise be subject to the foregoing restrictions) in an aggregate amount
that, together with all other such secured Debt and the aggregate amount of our
and our Subsidiaries' Attributable Indebtedness deemed to be outstanding in
respect of all Sale/Leaseback Transactions entered into pursuant to the
provisions described below under "-- Limitation on Sale/ Leaseback Transactions"
(excluding any such Sale/Leaseback Transactions the proceeds of which have been
applied in accordance with clauses (2) or (3) under the "-- Limitation on
Sale/Leaseback Transactions" covenant described below), does not exceed 10% of
the Consolidated Net Worth, as shown on a consolidated balance sheet as of a
date not more than 90 days prior to the proposed transaction we prepare in
accordance with generally accepted accounting principles.
 
                                       15
<PAGE>   38
 
     Limitation on Sale/Leaseback Transactions
 
     The Senior Debt Indenture provides that we will not, and will not permit
any of our Subsidiaries to, enter into any Sale/Leaseback Transaction with any
Person (other than ourselves or one of our Subsidiaries) unless:
 
          (1) at the time of entering into such Sale/Leaseback Transaction, we
     or such Subsidiary would be entitled to incur Debt, in a principal amount
     equal to the Attributable Indebtedness with respect to such Sale/Leaseback
     Transaction, secured by a mortgage on the property subject to such
     Sale/Leaseback Transaction, pursuant to the provisions of the covenant
     described under "-- Limitation on Liens" without equally and ratably
     securing the debt securities pursuant to such provisions;
 
          (2) after the date on which debt securities are first issued, and
     within a period commencing six months prior to the consummation of such
     Sale/Leaseback Transaction and ending six months after the consummation
     thereof, we or such Subsidiary shall have expended for property used or to
     be used in our or such Subsidiary's ordinary course of business (including
     amounts expended for additions, expansions, alterations, repairs and
     improvements thereto) an amount equal to all or a portion of the net
     proceeds of such Sale/Leaseback Transaction, and we shall have elected to
     designate such amount as a credit against such Sale/Leaseback Transaction
     (with any such amount not being so designated to be applied as set forth in
     clause (3) below); or
 
          (3) during the 12-month period after the effective date of such
     Sale/Leaseback Transaction, we shall have applied to the voluntary
     defeasance or retirement of debt securities or any of our pari passu
     indebtedness an amount equal to the net proceeds of the sale or transfer of
     the property leased in such Sale/Leaseback Transaction, which amount shall
     not be less than the fair value of such property at the time of entering
     into such Sale/Leaseback Transaction (adjusted to reflect any amount we
     expended as set forth in clause (2) above), less an amount equal to the
     principal amount of such debt securities and pari passu indebtedness we
     voluntarily defeased or retired within such 12-month period and not
     designated as a credit against any other Sale/Leaseback Transaction we or
     any of our Subsidiaries entered into during such period.
 
     Unless otherwise specified in the prospectus supplement relating to a
particular series of offered debt securities, the covenants applicable to the
debt securities would not necessarily afford holders protection in the event
that we are involved in a highly leveraged or other transaction, or in the event
of a material adverse change in our financial position or results of operations.
Unless otherwise specified in the prospectus supplement relating to a particular
series of offered debt securities, the debt securities do not contain any other
provisions that are designed to afford protection in the event that we are
involved in a highly leveraged transaction.
 
SUBORDINATED DEBT
 
     The debt securities and coupons, if any, attached to such debt securities
that will constitute part of the Subordinated Debt Securities will be issued
under the Subordinated Debt Indenture and will be subordinate and junior in
right of payment, to the extent and in the manner set forth in the Subordinated
Debt Indenture, to all of our Senior Indebtedness. The Subordinated Debt
Indenture defines "SENIOR INDEBTEDNESS" as all of our indebtedness, including
indebtedness we have guaranteed or assumed, for borrowed money or evidenced by
bonds, debentures, notes, letters of credit, interest rate exchange
 
                                       16
<PAGE>   39
 
agreements, currency exchange agreements, commodity forward contracts or other
similar instruments, or indebtedness or obligations with respect to any lease of
real or personal property whether existing on the date hereof or hereinafter
incurred, and any guarantee, amendments, renewals, extensions, modifications and
refundings of any such indebtedness or obligation, provided that Senior
Indebtedness shall not include (1) obligations that, when incurred and without
respect to any election under Section 1111(b) of Title 11, United States Code,
were without recourse to the issuer, (2) our obligations to any of our
Subsidiaries, and (3) any other obligations which by the terms of the instrument
creating or evidencing the same are specifically designated as not being senior
in right of payment to the Subordinated Debt Securities.
 
     In the event (1) of any insolvency or bankruptcy proceedings, or any
receivership, liquidation or other similar proceedings including reorganization
in respect of Borg-Warner Automotive or a substantial part of our property, or
(2) that (a) a default shall have occurred with respect to the payment of
principal of (and premium, if any) or any interest on or other monetary amounts
due and payable on any Senior Indebtedness or (b) there shall have occurred an
event of default (other than a default in the payment of principal, premium, if
any, or interest, or other monetary amounts due and payable) with respect to any
Senior Indebtedness, as defined therein or in the instrument under which the
same is outstanding, permitting the holder or holders thereof to accelerate the
maturity thereof, and such default or event of default shall not have been cured
or waived or shall not have ceased to exist, unless, in the case of a default
under clause (b) above, the default with respect to the Senior Indebtedness is
cured or waived, or 180 days pass after notice of the default is given to the
holders of Senior Indebtedness (unless the maturity of such Senior Indebtedness
has been accelerated), then the holders of all Senior Indebtedness shall first
be entitled to receive payment of the full amount unpaid thereon, or provision
shall be made, in accordance with the relevant Senior Indebtedness, for such
payment in money or money's worth, before the holders of any of the Subordinated
Debt Securities or coupons are entitled to receive a payment on account of the
principal of (and premium, if any) or any interest on the indebtedness evidenced
by such Subordinated Debt Securities or of such coupons. No new period of
suspension of payments under clause (b) above may be commenced by reason of the
same event of default (or any other event of default that existed or was
continuing on the date of the commencement of such period) within twelve months
after the first such notice relating thereto. Without limitation of the
foregoing, upon any acceleration of the Subordinated Debt Securities because of
an event of default, we must promptly notify the holders of Senior Indebtedness
of such acceleration, and may not pay the Subordinated Debt Securities unless
(A) 120 days pass after such acceleration and (B) the terms of the Subordinated
Debt Indenture permit such payment at such time.
 
     By reason of such subordination, in the event of our bankruptcy, insolvency
or liquidation, our creditors who are holders of Senior Indebtedness and our
general creditors may recover more, ratably, than holders of the Subordinated
Debt Securities. Certain of our contingent obligations, including certain
guarantees, letters of credit, interest rate exchange agreements, currency
exchange agreements and commodity forward contracts, would constitute Senior
Indebtedness if we became obligated to pay such contingent obligations.
 
     We expect from time to time to incur additional indebtedness constituting
Senior Indebtedness. The Subordinated Debt Indenture does not prohibit or limit
the incurrence of additional Senior Indebtedness or any other indebtedness and
does not require us to adhere to financial covenants or similar restrictions. To
the extent we issue Subordinated
 
                                       17
<PAGE>   40
 
Debt Securities, we refer you to the applicable prospectus supplement for the
amount of Senior Indebtedness outstanding.
 
CONVERSION AND EXCHANGE
 
     The terms, if any, on which debt securities of any series will be
convertible into or exchangeable for our common stock or preferred stock,
property or cash, or a combination of any of the foregoing, will be summarized
in the prospectus supplement relating thereto. Such terms may include provisions
for conversion or exchange, either on a mandatory basis, at the option of the
holder, or at our option, in which case the number of our shares of common stock
or preferred stock to be received by the holders of the debt securities would be
calculated according to the factors and at such time as summarized in the
related prospectus supplement. The prospectus supplement will also summarize the
material federal income tax consequences applicable to such convertible or
exchangeable debt securities to the extent not set forth in this prospectus.
 
EVENTS OF DEFAULT
 
     An "Event of Default" is defined under each Indenture with respect to debt
securities of any series issued under such Indenture as being:
 
     -  default in the payment of any interest on any debt security when it
        becomes due and payable, and continuance of such default for a period of
        30 days;
 
     -  default in the payment of the principal of any debt security at its
        maturity;
 
     -  default in our performance (or our breach) of any of our covenants or
        agreements in such Indenture, continued for 90 days after we receive
        written notice;
 
     -  acceleration of, or any failure to pay at final maturity, any of our or
        our Subsidiaries' Debt (other than the debt securities or Non-Recourse
        Indebtedness) in an aggregate amount in excess of $25 million if such
        acceleration is not rescinded or annulled, or such indebtedness shall
        not have been discharged, within 15 days after we receive written notice
        thereof; and
 
     -  certain events of our or of one of our Significant Subsidiaries'
        bankruptcy, insolvency or reorganization.
 
     Each Indenture provides that if an Event of Default, other than certain
events with respect to our bankruptcy, insolvency or reorganization, shall occur
and be continuing, then the Senior Trustee or the Subordinated Trustee, as the
case may be, or the holders of not less than 25% in aggregate principal amount
of the outstanding debt securities may, by a notice in writing to us (and to the
Senior Trustee or the Subordinated Trustee, as the case may be, if given by the
holders), declare the principal of the debt securities, and all accrued and
unpaid interest thereon, to be due and payable immediately. If an Event of
Default with respect to certain events of our bankruptcy, insolvency or
reorganization shall occur and be continuing, then the principal on the debt
securities, and all accrued and unpaid interest thereon, shall be due and
payable immediately without any act on the part of the Senior Trustee or the
Subordinated Trustee, as the case may be, or any holder.
 
     The holders of not less than a majority in principal amount of the
outstanding debt securities may, on behalf of the holders of all of the debt
securities, waive any past default under the Indenture and its consequences,
except a default (1) in respect of the payment of principal of or interest on
the debt securities or (2) in respect of a covenant or provision that cannot be
modified or amended without the consent of each holder.
 
                                       18
<PAGE>   41
 
     Under each Indenture we are required to file annually with the Senior
Trustee or the Subordinated Trustee, as the case may be, an officers'
certificate as to our compliance with all conditions and covenants. Each
Indenture will provide that the Senior Trustee or the Subordinated Trustee, as
the case may be, may withhold notice to the holders of the debt securities of
any default (except payment defaults on the debt securities) if it considers it
to be in the interest of such holders to do so.
 
     Subject to the provisions of each Indenture relating to the duties of the
Senior Trustee or the Subordinated Trustee, as the case may be, each Indenture
provides that when an Event of Default occurs and is continuing, the Senior
Trustee or the Subordinated Trustee, as the case may be, will be under no
obligation to exercise any of its rights or powers under such Indenture at the
request or direction of any of the holders, unless such holders shall have
offered to the Senior Trustee or the Subordinated Trustee, as the case may be,
reasonable security or indemnity. Subject to such provisions concerning the
rights of the Senior Trustee or the Subordinated Trustee, as the case may be,
the holders of a majority in aggregate principal amount of the outstanding debt
securities will have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Senior Trustee or the
Subordinated Trustee, as the case may be, or exercising any trust or power
conferred on the Senior Trustee or the Subordinated Trustee, as the case may be,
under such Indenture.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     Each Indenture provides that we will not consolidate with or merge into any
other corporation, or convey, transfer or lease, or permit one or more of our
Significant Subsidiaries to convey, transfer or lease, all or substantially all
of our property and assets on a consolidated basis, to any Person unless (1)
either we are the continuing corporation or such corporation or Person assumes
by supplemental indenture all of our obligations under such Indenture and the
debt securities issued thereunder, (2) immediately after such transaction no
Default or Event of Default shall exist, and (3) the surviving corporation or
such Person is a corporation, partnership or trust organized and validly
existing under the laws of the United States of America, any state thereof or
the District of Columbia.
 
MODIFICATION OR WAIVER
 
     Each Indenture provides that we may modify and amend such Indenture, and
the Senior Trustee or the Subordinated Trustee, as the case may be, may modify
and amend such Indenture with the consent of the holders of not less than a
majority in principal amount of the outstanding debt securities; provided that
no such modification or amendment may, without the consent of each holder, among
other things:
 
     -  change the maturity of the principal of, or any installment of interest
        on, the debt securities;
 
     -  reduce the principal amount of, or the rate of interest on, the debt
        securities;
 
     -  change the place or currency of payment of principal of, or interest on,
        the debt securities;
 
     -  impair the right to institute suit for the enforcement of any such
        payment on or after the maturity thereof;
 
                                       19
<PAGE>   42
 
     -  reduce the percentage of holders necessary to modify or amend such
        Indenture or to consent to any waiver thereunder or reduce the
        requirements for voting or quorum described below; or
 
     -  modify the foregoing requirements or reduce the percentage of
        outstanding debt securities necessary to waive any past default.
 
     Each Indenture provides that we may modify and amend such Indenture and the
Senior Trustee or the Subordinated Trustee, as the case may be, may modify and
amend such Indenture without the consent of any holder for any of the following
purposes:
 
     -  to evidence the succession of another Person to Borg-Warner Automotive
        and the assumption by such Person of our covenants contained in such
        Indenture and the debt securities;
 
     -  to add covenants of Borg-Warner Automotive for the benefit of the
        holders or to surrender any right or power conferred upon our company;
 
     -  to add Events of Default;
 
     -  to secure the debt securities;
 
     -  to evidence and provide for the acceptance of appointment by a successor
        Senior Trustee or a successor Subordinated Trustee, as the case may be;
 
     -  to cure any ambiguity, defect or inconsistency in such Indenture;
        provided such action does not adversely affect the interests of the
        holders;
 
     -  to supplement any of the provisions of such Indenture to the extent
        necessary to permit or facilitate defeasance and discharge of the debt
        securities; provided such action shall not adversely affect the
        interests of the holders; or
 
     -  to conform with the requirements of the TIA.
 
DEFEASANCE AND COVENANT DEFEASANCE
 
     We may, at our option and at any time, terminate our obligations with
respect to the outstanding debt securities ("DEFEASANCE"). Defeasance means that
we will be deemed to have paid and discharged the entire indebtedness
represented by the outstanding debt securities, except for (1) the rights of the
holders of outstanding debt securities to receive payment in respect of the
principal of and interest on such debt securities when such payments are due,
(2) our obligations to issue temporary debt securities, register and transfer or
exchange any debt securities, replace mutilated, destroyed, lost or stolen debt
securities, maintain an office or agency for payments in respect of the debt
securities and segregate and hold money in trust, (3) the rights, powers,
trusts, duties and immunities of the Senior Trustee or the Subordinated Trustee,
as the case may be, and (4) the Defeasance provisions of the applicable
Indenture. In addition, we may, at our option and at any time, elect to
terminate our obligations with respect to the debt securities (being primarily
the restrictions described under "-- Limitation on Liens" and "-- Limitation on
Sale/Leaseback Transactions"), and any omission to comply with such obligations
will not constitute a Default or an Event of Default with respect to the debt
securities ("COVENANT DEFEASANCE").
 
     In order to exercise either Defeasance or Covenant Defeasance:
 
     -  we must irrevocably deposit with the Senior Trustee or the Subordinated
        Trustee, as the case may be, in trust, for the benefit of the holders,
        cash in United States
 
                                       20
<PAGE>   43
 
        dollars, U.S. Government Obligations, or a combination thereof, in such
        amounts as will be sufficient, in the opinion of a nationally recognized
        firm of independent public accountants, to pay the principal of and
        interest on the outstanding debt securities to maturity;
 
     -  we must deliver to the Senior Trustee or the Subordinated Trustee, as
        the case may be, an opinion of counsel to the effect that the holders of
        the outstanding debt securities will not recognize income, gain or loss
        for federal income tax purposes as a result of such Defeasance or
        Covenant Defeasance, and will be subject to federal income tax on the
        same amounts, in the same manner and at the same times as would have
        been the case if such Defeasance or Covenant Defeasance had not occurred
        (in the case of Defeasance, such opinion must refer to and be based upon
        a ruling of the Internal Revenue Service or a change in applicable
        federal income tax laws);
 
     -  no Default or Event of Default shall have occurred and be continuing on
        the date of such deposit or, insofar as the last bullet point under the
        first paragraph under "-- Events of Default" is concerned, at any time
        during the period ending the 91st day after the date of deposit (it
        being understood that this condition shall not be deemed satisfied until
        the expiration of such period);
 
     -  such Defeasance or Covenant Defeasance shall not cause the Senior
        Trustee or the Subordinated Trustee, as the case may be, to have a
        conflicting interest (as defined by the TIA) with respect to any of our
        securities;
 
     -  such Defeasance or Covenant Defeasance shall not result in a breach or
        violation of, or constitute a default under, the applicable Indenture or
        any material agreement or instrument to which we are a party or by which
        we are bound; and
 
     -  we shall have delivered to the Senior Trustee or the Subordinated
        Trustee, as the case may be, an officers' certificate and an opinion of
        counsel, each stating that all conditions precedent under the applicable
        Indenture to either Defeasance or Covenant Defeasance, as the case may
        be, have been complied with and that no violations under agreements
        governing any other outstanding Debt would result.
 
SATISFACTION AND DISCHARGE
 
     Each Indenture provides that it will be discharged and will cease to be of
further effect (except as to any surviving rights of registration of transfer or
exchange of the debt securities, as expressly provided for in such Indenture) as
to all outstanding debt securities when (1) either (a) all the debt securities
theretofore authenticated and delivered (except lost, stolen or destroyed debt
securities which have been replaced or paid and debt securities for whose
payment money or certain U.S. Government Obligations has theretofore been
deposited in trust or segregated and held in trust by us and thereafter repaid
to us or discharged from such trust) have been delivered to the Senior Trustee
or the Subordinated Trustee, as the case may be, for cancellation or (b) all
debt securities not theretofore delivered to the Senior Trustee or the
Subordinated Trustee, as the case may be, for cancellation have become due and
payable or will become due and payable at maturity within one year and we have
irrevocably deposited or caused to be deposited with the Senior Trustee or the
Subordinated Trustee, as the case may be, funds in an amount sufficient to pay
and discharge the entire indebtedness on the debt securities not theretofore
delivered to the Senior Trustee or the Subordinated Trustee, as the case may be,
for cancellation, for principal of and interest on the debt securities to the
date of
 
                                       21
<PAGE>   44
 
deposit together with irrevocable instructions from us directing the Senior
Trustee or the Subordinated Trustee, as the case may be, to apply such funds to
the payment thereof at maturity; (2) we have paid or have caused to be paid all
other sums payable under such Indenture by us; and (3) we have delivered to the
Senior Trustee or the Subordinated Trustee, as the case may be, an officers'
certificate and an opinion of counsel stating that all conditions precedent
under such Indenture relating to the satisfaction and discharge of such
Indenture have been complied with.
 
BOOK-ENTRY SYSTEM
 
     Unless otherwise specified in the applicable prospectus supplement, any
debt securities will be represented by certificate in book-entry form ("GLOBAL
DEBT SECURITIES") as set forth below.
 
     Any Global Debt Securities will be registered in the name of The Depository
Trust Company's ("DTC") nominee. Except as set forth below, a Global Debt
Security may not be transferred except as a whole by DTC to a nominee of DTC or
by a nominee of DTC to DTC or another nominee of DTC or by DTC or any such
nominee to a successor of DTC or a nominee of such successor.
 
     DTC has advised us that it is a limited-purpose trust company organized
under the laws of the State of New York, a member of the Federal Reserve System,
a "clearing corporation" within the meaning of the New York Uniform Commercial
Code and a "clearing agency" registered pursuant to the provisions of Section
17A of the Exchange Act. DTC was created to hold securities of its participants
and to facilitate the clearance and settlement of securities transactions among
its participants in such securities through electronic book-entry changes in
accounts of the participants, thereby eliminating the need for physical movement
of securities certificates. DTC's participants include securities brokers and
dealers, banks, trust companies, clearing corporations and certain other
organizations, some of whom (and/or their representatives) own DTC. Access to
DTC's book-entry system is also available to others, such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly. Persons who are
not participants may beneficially own securities held by DTC only through
participants.
 
     Upon the issuance by us of any Global Debt Securities, DTC will credit, on
its book-entry registration and transfer system, the respective principal
amounts of debt securities to the accounts of participants. The accounts to be
credited will be designated by the applicable underwriter. Ownership of
beneficial interests in a Global Debt Security will be limited to participants
or persons that may hold interests through participants. Beneficial interests in
a Global Debt Security will be shown on, and the transfer thereof will be
effected only through, records maintained by DTC (with respect to beneficial
interests of participants) or by participants or persons that may hold interests
through participants (with respect to beneficial interests of beneficial
owners). The laws of some states require that certain purchasers of securities
take physical delivery of such securities in certificated form. Such limits and
such laws may impair the ability to transfer beneficial interests in a Global
Debt Security.
 
     For a Global Debt Security, so long as DTC or its nominee is the registered
owner of such Global Debt Security, DTC or its nominee, as the case may be, will
be considered the sole owner or holder of the debt securities represented by
such Global Debt Security for all purposes under the Senior Debt Indenture.
Except as provided below, owners of beneficial interests in a Global Debt
Security will not be entitled to have debt securities

represented by such Global Debt Security registered in their names, will not
receive or be entitled to receive physical delivery of such debt securities in
certificated form and will not be considered the owners or holders thereof under
the Senior Debt Indenture or the Subordinated Debt Indenture, as the case may
be.
 
     Principal and interest payments in respect of the debt securities will be
made in immediately available funds by us to DTC or its nominee, as the case may
be, as the holder of the related Global Debt Securities. None of us, the Senior
Trustee or the Subordinated Trustee will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests in any Global Debt Securities, or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests. None of us, the Senior Trustee or the Subordinated Trustee
will have any responsibility or liability for DTC's exercise of or failure to
exercise any redemption option with respect to any debt securities on behalf of
any holder of a beneficial interest therein, other than our obligation to redeem
such debt securities if such option is properly exercised by DTC or its nominee,
as registered holder, in accordance with the procedures specified therefor. We
expect that DTC, upon receipt of any payment of principal or interest in respect
of any Global Debt Securities, will credit immediately the accounts of the
related participants with payment in amounts proportionate to their respective
beneficial interests in the principal amount of such Global Debt Securities as
shown on the records of DTC. We also expect that payments by participants to
owners of beneficial interests in any Global Debt Securities will be governed by
standing customer instructions and customary practices, as is now the case, with
securities held for the accounts of customers in bearer form or registered in
"street name," and will be the responsibility of such participants. Payments to
DTC in respect of the debt securities which are represented by any Global Debt
Securities shall be our responsibility or the responsibility of the Senior
Trustee or the Subordinated Trustee, as the case may be. Disbursement of such
payments to direct participants shall be the responsibility of DTC and
disbursement of such payments to beneficial owners shall be the responsibility
of direct and indirect participants.
 
     Conveyance of notices and other communications by DTC to direct
participants, by direct participants to indirect participants and by direct and
indirect participants to beneficial owners, and vice versa, are governed by
arrangements among them, subject to statutory or regulatory requirements as may
be in effect from time to time; and none of us, the Senior Trustee or the
Subordinated Trustee will have any responsibility or liability with respect
thereto.
 
     The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that we believe to be reliable, but we take no
responsibility for the accuracy of such information.
 
     If DTC is at any time unwilling or unable to continue as depository and we
do not appoint a successor depository within 90 days, we will issue debt
securities in certificated form in exchange for each Global Debt Security. In
addition, we may at any time determine not to have one or more series of debt
securities represented by any Global Debt Securities. In any such instance,
owners of beneficial interests in any such Global Debt Security will be entitled
to physical delivery of debt securities in certificated form equal in principal
amount to such beneficial interest and to have such debt securities registered
in their names. Debt securities so issued in certificated form will be issued in
denominations of $1,000 or any integral multiple thereof and will be issued in
registered form only, without coupons.

THE TRUSTEES
 
     The Indentures and provisions of the TIA incorporated by reference therein
contain limitations on the rights of the Senior Trustee or the Subordinated
Trustee, as the case may be thereunder, should the Senior Trustee or the
Subordinated Trustee, as the case may be, become one of our creditors, to obtain
payment of claims in certain cases. We may from time to time maintain bank
accounts and have other customary banking relationships with and obtain credit
facilities and lines of credit from the Senior Trustee or the Subordinated
Trustee, in the ordinary course of business; provided, however, that if the
Senior Trustee or the Subordinated Trustee, as the case may be, acquires any
conflicting interest (as defined in Section 310(b) of the TIA), it must
eliminate such conflict or resign.
 
     We will appoint the Senior Trustee or the Subordinated Trustee, as the case
may be, at the offices specified in the applicable Indenture as registrar,
principal paying agent and transfer agent for the debt securities. In such
capacities, the Senior Trustee or the Subordinated Trustee, as the case may be,
will be responsible for, among other things, (1) maintaining a record of the
aggregate holdings of debt securities represented by the Global Debt Security
and accepting debt securities for exchange and registration of transfer, (2)
ensuring that payments of principal of and interest on the Global Debt Security
and other debt securities received from us by the Senior Trustee or the
Subordinated Trustee, as the case may be, are duly paid to DTC or its nominee or
the holders thereof, as the case may be, and (3) transmitting to us any notices
from holders of debt securities. We will cause the transfer agent to act as a
registrar. We may vary or terminate the appointment of the transfer agent or
appoint additional or other transfer agents or approve any change in the office
through which any transfer agent acts.
 
                          CERTAIN U.S. FEDERAL INCOME
                               TAX CONSIDERATIONS
 
     The following is a summary of the material U.S. federal income tax
consequences of the acquisition, ownership and disposition by a U.S. Holder (as
defined below) or a United States Alien Holder (as defined below) of debt
securities issued in registered form. In the event that we issue debt securities
in bearer form, the applicable prospectus supplement will describe the material
federal income tax consequences thereof.
 
     The discussion does not cover all aspects of federal taxation that may be
relevant to, or the actual tax effect that any of the matters described herein
will have on, the acquisition, ownership or disposition of debt securities by
particular investors, and does not address state, local, foreign or other tax
laws. In particular, this summary addresses only investors that will hold the
debt securities as capital assets and does not discuss all of the tax
considerations that may be relevant to certain types of investors subject to
special treatment under the federal income tax laws (such as banks, insurance
companies, investors liable for the alternative minimum tax, individual
retirement accounts and other tax-deferred accounts, tax-exempt organizations,
dealers in securities or currencies, traders in securities that elect to mark to
market for U.S. federal income tax purposes, investors that will hold the debt
securities as part of straddles, hedging transactions or conversion transactions
for federal tax purposes, investors whose functional currency is not the U.S.
dollar or investors who enter into "constructive sales" of the debt securities).
Additional United States federal income tax consequences applicable to
particular debt securities may be set forth in the applicable prospectus
supplement.

     As used herein, the term "U.S. HOLDER" means a beneficial owner of debt
securities that is (1) a citizen or individual resident of the United States for
U.S. federal income tax purposes, (2) a corporation, partnership or limited
liability company created or organized under the laws of the United States, any
State thereof or the District of Columbia, (3) an estate the income of which is
subject to U.S. federal income tax on a net income basis regardless of its
source or (4) a trust if a court within the United States is able to exercise
primary supervision over the administration of the trust and one or more United
States persons has the authority to control all substantial decisions of the
trust. A "UNITED STATES ALIEN HOLDER" is any holder who or that is not a U.S.
Holder.
 
     This summary is based on the Internal Revenue Code of 1986, as amended (the
"CODE"), its legislative history, existing and proposed regulations thereunder,
published rulings and court decisions, all as currently in effect and all
subject to change at any time, perhaps with retroactive effect.
 
THIS SUMMARY IS FOR GENERAL INFORMATION ONLY. YOU ARE URGED TO CONSULT YOUR
PERSONAL TAX ADVISORS AS TO THE PARTICULAR FEDERAL, STATE, LOCAL, FOREIGN AND
OTHER TAX CONSEQUENCES TO YOU OF ACQUIRING, OWNING AND DISPOSING OF THE DEBT
SECURITIES.
 
U.S. HOLDERS
 
     Except where otherwise expressly indicated, this summary under "U.S.
Holders" deals only with initial purchasers of debt securities at the issue
price that are U.S. Holders.
 
     PAYMENTS OF INTEREST
 
     General.  Interest on a debt security, whether payable in U.S. dollars or a
currency, composite currency or basket of currencies other than U.S. dollars (a
"FOREIGN CURRENCY"), other than interest on a "Discount Debt Security" that is
not "qualified stated interest" (each as defined below under "-- Original Issue
Discount -- General"), will be taxable to a U.S. Holder as ordinary income at
the time it is received or accrued, depending on the holder's method of
accounting for tax purposes.
 
     Foreign Currency Denominated Interest.  If an interest payment is
denominated in, or determined by reference to, a foreign currency, the amount of
income recognized by a cash basis U.S. Holder will be the U.S. dollar value of
the interest payment, based on the exchange rate in effect on the date of
receipt, regardless of whether the payment is in fact converted into U.S.
dollars.
 
     An accrual basis U.S. Holder may determine the amount of income recognized
with respect to an interest payment denominated in, or determined by reference
to, a foreign currency in accordance with either of two methods. Under the first
method, the amount of income accrued will be based on the average exchange rate
in effect during the interest accrual period (or, with respect to an accrual
period that spans two taxable years of a U.S. Holder, the part of the period
within the taxable year).
 
     Under the second method, the U.S. Holder may elect to determine the amount
of income accrued on the basis of the exchange rate in effect on the last day of
the accrual period or, in the case of an accrual period that spans two taxable
years, the exchange rate in effect on the last day of the part of the period
within the taxable year. Additionally, if a payment of interest is actually
received within five business days of the last day of the accrual period or
taxable year, an electing accrual basis U.S. Holder may instead translate such
accrued interest into U.S. dollars at the exchange rate in effect on the day of
actual
 
                                       25
<PAGE>   48
 
receipt. Any such election will apply to all debt instruments held by the U.S.
Holder at the beginning of the first taxable year to which the election applies
or thereafter acquired by the U.S. Holder, and will be irrevocable without the
consent of the Internal Revenue Service (the "IRS").
 
     Upon receipt of the interest payment (including a payment attributable to
accrued but unpaid interest upon the sale or retirement of a debt security)
denominated in, or determined by reference to, a foreign currency, an accrual
basis U.S. Holder that is required to accrue interest income prior to the date
of receipt will recognize ordinary income or loss measured by the difference
between the exchange rate used to accrue interest income pursuant to one of the
two above methods and the exchange rate in effect on the date of receipt,
regardless of whether the payment is in fact converted into U.S. dollars.
 
     ORIGINAL ISSUE DISCOUNT
 
     General.  The following is a summary of the principal federal income tax
consequences of the ownership of debt securities issued at an original issue
discount. It is based in part upon the rules governing original issue discount
that are set forth in Sections 1271 through 1275 of the Code and in Treasury
regulations thereunder (the "OID REGULATIONS"). The following summary does not
discuss the federal income tax consequences of an investment in contingent
payment debt instruments. In the event we issue contingent payment debt
instruments, the applicable prospectus supplement will describe the material
federal income tax consequences thereof.
 
     A debt security, other than a debt security with a term of one year or less
(a "SHORT-TERM DEBT SECURITY"), will be treated as issued at an original issue
discount (a "DISCOUNT DEBT SECURITY") if the excess of the debt security's
"stated redemption price at maturity" over its issue price is more than a "de
minimis amount" (as defined below). Generally, the issue price of a debt
security will be the first price at which a substantial amount of debt
securities included in the issue of which the debt security is a part is sold to
persons other than bond houses, brokers, or similar persons or organizations
acting in the capacity of underwriters, placement agents, or wholesalers. The
stated redemption price at maturity of a debt security is the total of all
payments provided by the debt security that are not payments of "QUALIFIED
STATED INTEREST." A qualified stated interest payment is generally any one of a
series of stated interest payments on a debt security that are unconditionally
payable at least annually during the entire term of the debt security at a
single fixed rate (with certain exceptions for lower rates paid during some
periods) applied to the outstanding principal amount of the debt security.
Special rules for "Floating Rate Debt Securities" (as defined below under "--
Original Issue Discount -- Floating Rate Debt Securities") are described below
under "-- Original Issue Discount -- Floating Rate Debt Securities."
 
     In general, if the excess of a debt security's stated redemption price at
maturity over its issue price is less than 1/4 of 1 percent of the debt
security's stated redemption price at maturity multiplied by the number of
complete years to its maturity (the "DE MINIMIS AMOUNT"), then such excess, if
any, constitutes "DE MINIMIS ORIGINAL ISSUE DISCOUNT" and the debt security is
not a Discount Debt Security. Unless the election described below under
"Original Issue Discount -- Election to Treat All Interest as Original Issue
Discount" is made, a U.S. Holder of a debt security with de minimis original
issue discount must include such de minimis original issue discount in income as
capital gain as stated principal payments on the debt security are made. The
includible amount with
 
                                       26
<PAGE>   49
 
respect to each such payment will equal the product of the total amount of the
debt security's de minimis original issue discount and a fraction, the numerator
of which is the amount of the principal payment made and the denominator of
which is the stated principal amount of the debt security.
 
     U.S. Holders of Discount debt securities having a maturity of more than one
year from their date of issue must include original issue discount ("OID") in
income calculated on a constant-yield method before the receipt of cash
attributable to such income, and generally will have to include in income
increasingly greater amounts of OID over the life of the debt security. The
amount of OID includible in income by a U.S. Holder of a Discount Debt Security
is the sum of the daily portions of OID with respect to the Discount Debt
Security for each day during the taxable year or portion of the taxable year on
which the U.S. Holder holds such Discount Debt Security ("ACCRUED OID"). The
daily portion is determined by allocating to each day in any "accrual period" a
pro rata portion of the OID allocable to that accrual period. Accrual periods
with respect to a debt security may be of any length selected by the U.S. Holder
and may vary in length over the term of the debt security as long as (1) no
accrual period is longer than one year and (2) each scheduled payment of
interest or principal on the debt security occurs on either the final or first
day of an accrual period. The amount of OID allocable to an accrual period
equals the excess of (a) the product of the Discount debt security's adjusted
issue price at the beginning of the accrual period and such debt security's
yield to maturity (determined on the basis of compounding at the close of each
accrual period and properly adjusted for the length of the accrual period) over
(b) the sum of the payments of qualified stated interest on the debt security
allocable to the accrual period. The "ADJUSTED ISSUE PRICE" of a Discount Debt
Security at the beginning of any accrual period is the issue price of the debt
security increased by (x) the amount of accrued OID for each prior accrual
period and decreased by (y) the amount of any payments previously made on the
debt security that were not qualified stated interest payments. For purposes of
determining the amount of OID allocable to an accrual period, if an interval
between payments of qualified stated interest on the debt security contains more
than one accrual period, the amount of qualified stated interest payable at the
end of the interval (including any qualified stated interest that is payable on
the first day of the accrual period immediately following the interval) is
allocated pro rata on the basis of relative lengths to each accrual period in
the interval, and the adjusted issue price at the beginning of each accrual
period in the interval must be increased by the amount of any qualified stated
interest that has accrued prior to the first day of the accrual period but that
is not payable until the end of the interval. The amount of OID allocable to an
initial short accrual period may be computed using any reasonable method if all
other accrual periods other than a final short accrual period are of equal
length. The amount of OID allocable to the final accrual period is the
difference between (x) the amount payable at the maturity of the debt security
(other than any payment of qualified stated interest) and (y) the debt
security's adjusted issue price as of the beginning of the final accrual period.
 
     Acquisition Premium.  A U.S. Holder that purchases a Discount Debt Security
for an amount less than or equal to the sum of all amounts payable on the debt
security after the purchase date other than payments of qualified stated
interest but in excess of its adjusted issue price (any such excess being
"ACQUISITION PREMIUM") and that does not make the election described below under
"Original Issue Discount -- Election to Treat All Interest as Original Issue
Discount" is permitted to reduce the daily portions of OID by a fraction, the
numerator of which is the excess of the U.S. Holder's adjusted basis in the debt
security immediately after its purchase over the adjusted issue price of the
debt security,
 
                                       27
<PAGE>   50
 
and the denominator of which is the excess of the sum of all amounts payable on
the debt security after the purchase date, other than payments of qualified
stated interest, over the debt security's adjusted issue price.
 
     Pre-Issuance Accrued Interest.  If (1) a portion of the initial purchase
price of a debt security is attributable to pre-issuance accrued interest, (2)
the first stated interest payment on the debt security is to be made within one
year of the debt security's issue date and (3) the payment will equal or exceed
the amount of pre-issuance accrued interest, then the issue price of the debt
security may be computed by reducing the issue price (as determined under
"-- Original Issue Discount -- General") by the amount of pre-issuance accrued
interest. In that event, a portion of the first stated interest payment will be
treated as a return of the excluded pre-issuance accrued interest and not as an
amount payable on the debt security.
 
     Debt Securities Subject to Contingencies Including Optional Redemption.  In
general, if a debt security provides for an alternative payment schedule or
schedules applicable upon the occurrence of a contingency or contingencies and
the timing and amounts of the payments that comprise each payment schedule are
known as of the issue date, and if, based on all the facts and circumstances as
of the issue date, a single payment schedule is significantly more likely than
not to occur, then the yield and maturity of the debt security are computed
based on that payment schedule.
 
     Notwithstanding the general rule described in the preceding paragraph, if
we have an unconditional option or options to redeem a debt security, or the
Holder has an unconditional option or options to cause a debt security to be
repurchased, prior to the debt security's stated maturity, then (1) in the case
of our option or options, we will be deemed to exercise or not exercise an
option or combination of options in the manner that minimizes the yield on the
debt security and (2) in the case of an option or options of the Holder, the
Holder will be deemed to exercise or not exercise an option or combination of
options in the manner that maximizes the yield on the debt security. For
purposes of those calculations, the yield on the debt security is determined by
using any date on which the debt security may be redeemed or repurchased as the
maturity date and the amount payable on such date in accordance with the terms
of the debt security as the principal amount payable at maturity.
 
     If a contingency (including the exercise of an option) actually occurs or
does not occur contrary to an assumption made according to the above rules (a
"CHANGE IN CIRCUMSTANCES") then, except to the extent that a portion of the debt
security is repaid as a result of the change in circumstances and solely for
purposes of the accrual of OID, the yield and maturity of the debt security are
redetermined by treating the debt security as reissued on the date of the change
in circumstances for an amount equal to the debt security's adjusted issue price
on that date.
 
     Election to Treat All Interest as Original Issue Discount.  A U.S. Holder
may elect to include in gross income all interest that accrues on a debt
security using the constant-yield method described above under the heading
"Original Issue Discount -- General," with the modifications described below.
For purposes of this election, interest includes stated interest, OID, de
minimis original issue discount, market discount, de minimis market discount and
unstated interest, as adjusted by any amortizable bond premium (described below
under "U.S. Holders -- Debt Securities Purchased at a Premium") or acquisition
premium.
 
                                       28
<PAGE>   51
 
     In applying the constant-yield method to a debt security with respect to
which this election has been made, the issue price of the debt security will
equal the electing U.S. Holder's adjusted basis in the debt security immediately
after its acquisition, the issue date of the debt security will be the date of
its acquisition by the electing U.S. Holder, and no payments on the debt
security will be treated as payments of qualified stated interest. This election
will generally apply only to the debt security with respect to which it is made
and may not be revoked without the consent of the IRS. If this election is made
with respect to a debt security with amortizable bond premium, then the electing
U.S. Holder will be deemed to have elected to apply amortizable bond premium
against interest with respect to all debt instruments with amortizable bond
premium (other than debt instruments the interest on which is excludible from
gross income) held by the electing U.S. Holder as of the beginning of the
taxable year in which the debt security with respect to which the election is
made is acquired or thereafter acquired. The deemed election with respect to
amortizable bond premium may not be revoked without the consent of the IRS.
 
     If the election to apply the constant-yield method to all interest on a
debt security is made with respect to a Market Discount Debt Security (as
defined below under "U.S. Holders -- Market Discount"), the electing U.S. Holder
will be treated as having made the election discussed below under "-- Market
Discount" to include market discount in income currently over the life of all
debt instruments with market discount acquired by the electing U.S. Holder on or
after the first day of the first taxable year to which the election applies.
 
     Floating Rate Debt Securities.  Debt securities that bear interest at a
floating rate ("FLOATING RATE DEBT SECURITIES") generally will bear interest at
a "qualified floating rate" and thus will be treated as "variable rate debt
instruments" under the OID Regulations. A Floating Rate Debt Security will
qualify as a "variable rate debt instrument" under the OID Regulations if (a)
its issue price does not exceed the total noncontingent principal payments due
under the Floating Rate Debt Security by more than a specified de minimis amount
and (b) it does not provide for stated interest other than stated interest, paid
or compounded at least annually, at current values of (1) one or more qualified
floating rates, (2) a single fixed rate and one or more qualified floating
rates, (3) a single "objective rate," or (4) a single fixed rate and a single
objective rate that is a qualified inverse floating rate.
 
     A "QUALIFIED FLOATING RATE" is any variable rate where variations in the
value of such rate can reasonably be expected to measure contemporaneous
variations in the cost of newly borrowed funds in the currency in which the
Floating Rate Debt Security is denominated. Although a multiple of a qualified
floating rate will generally not itself constitute a qualified floating rate, a
variable rate equal to the product of a qualified floating rate and a fixed
multiple that is greater than 0.65 but not more than 1.35 will constitute a
qualified floating rate. A variable rate equal to the product of a qualified
floating rate and a fixed multiple that is greater than 0.65 but not more than
1.35, increased or decreased by a fixed rate, will also constitute a qualified
floating rate. In addition, under the OID Regulations, if a debt security
provides for two or more qualified floating rates that can reasonably be
expected to have approximately the same values throughout the term of the
Floating Rate Debt Security (e.g., two or more qualified floating rates with
values within 25 basis points of each other as determined on the Floating Rate
Debt Security's issue date), then such qualified floating rates will be treated
as a single qualified floating rate. Notwithstanding the foregoing, a variable
rate that would otherwise constitute a qualified floating rate but which is
subject to one or more restrictions, such as a maximum numerical limitation
(i.e., a cap) or a minimum
 
                                       29
<PAGE>   52
 
numerical limitation (i.e., a floor), may, under certain circumstances, fail to
be treated as a qualified floating rate under the OID Regulations unless such
cap or floor is fixed throughout the term of the debt security or is not
reasonably expected significantly to affect the yield on the debt security.
 
     An "OBJECTIVE RATE" is a rate that is not itself a qualified floating rate
but which is determined using a single fixed formula and which is based upon
objective financial or economic information (e.g., one or more qualified
floating rates or the yield of actively traded personal property) that is not
within the control of the issuer or a related party and is not unique to the
circumstances of the issuer or a related party, such as dividends, profits or
the value of the issuer's stock. The OID Regulations also provide that other
variable interest rates may be treated as objective rates if so designated by
the IRS in the future. Despite the foregoing, a variable rate of interest on a
Floating Rate Debt Security will not constitute an objective rate if it is
reasonably expected that the average value of such rate during the first half of
the Floating Rate Debt Security's term will be either significantly less than or
significantly greater than the average value of the rate during the final half
of the Floating Rate Debt Security's term. A "QUALIFIED INVERSE FLOATING RATE"
is any objective rate where such rate is equal to a fixed rate minus a qualified
floating rate, as long as variations in the rate can reasonably be expected to
reflect inversely contemporaneous variations in the qualified floating rate. The
OID Regulations also provide that if a Floating Rate Debt Security provides for
stated interest at a fixed rate for an initial period of one year or less
followed by a variable rate that is either a qualified floating rate or an
objective rate and if the variable rate on the Floating Rate Debt Security's
issue date is intended to approximate the fixed rate (e.g., the value of the
variable rate on the issue date does not differ from the value of the fixed rate
by more than 25 basis points), then the fixed rate and the variable rate
together will constitute either a single qualified floating rate or objective
rate, as the case may be.
 
     A qualified floating rate or objective rate in effect at any time during
the term of the instrument must be set at a "current value" of that rate. A
"CURRENT VALUE" of a rate is the value of the rate on any day that is no earlier
than 3 months prior to the first day on which that value is in effect and no
later than 1 year following that first day.
 
     If a Floating Rate Debt Security that provides for stated interest at
either a single qualified floating rate or a single objective rate throughout
the term thereof qualifies as a "variable rate debt instrument" under the OID
Regulations, then any stated interest on such Floating Rate Debt Security which
is unconditionally payable in cash or property (other than our debt instruments)
at least annually will constitute qualified stated interest and will be taxed
accordingly. Thus, a Floating Rate Debt Security that provides for stated
interest at either a single qualified floating rate or a single objective rate
throughout the term thereof and that qualifies as a "variable rate debt
instrument" under the OID Regulations will generally not be treated as having
been issued with OID unless the Floating Rate Debt Security is issued at a
"true" discount (i.e., at a price below the debt security's stated principal
amount) in excess of a specified de minimis amount. OID on such a Floating Rate
Debt Security arising from "true" discount is allocated to an accrual period
using the constant yield method described above by assuming that the variable
rate is a fixed rate equal to (1) in the case of a qualified floating rate or
qualified inverse floating rate, the value, as of the issue date, of the
qualified floating rate or qualified inverse floating rate, or (2) in the case
of an objective rate (other than a qualified inverse floating rate), a fixed
rate that reflects the yield that is reasonably expected for the Floating Rate
Debt Security.
 
                                       30
<PAGE>   53
 
     In general, any other Floating Rate Debt Security that qualifies as a
"variable rate debt instrument" will be converted into an "equivalent" fixed
rate debt instrument for purposes of determining the amount and accrual of OID
and qualified stated interest on the debt security. The OID Regulations
generally require that such a Floating Rate Debt Security be converted into an
"equivalent" fixed rate debt instrument by substituting any qualified floating
rate or qualified inverse floating rate provided for under the terms of the
Floating Rate Debt Security with a fixed rate equal to the value of the
qualified floating rate or qualified inverse floating rate, as the case may be,
as of the Floating Rate Debt Security's issue date. Any objective rate (other
than a qualified inverse floating rate) provided for under the terms of the
Floating Rate Debt Security is converted into a fixed rate that reflects the
yield that is reasonably expected for the Floating Rate Debt Security. In the
case of a Floating Rate Debt Security that qualifies as a "variable rate debt
instrument" and provides for stated interest at a fixed rate in addition to
either one or more qualified floating rates or a qualified inverse floating
rate, the fixed rate is initially converted into a qualified floating rate (or a
qualified inverse floating rate, if the Floating Rate Debt Security provides for
a qualified inverse floating rate). Under such circumstances, the qualified
floating rate or qualified inverse floating rate that replaces the fixed rate
must be such that the fair market value of the Floating Rate Debt Security as of
the Floating Rate Debt Security's issue date is approximately the same as the
fair market value of an otherwise identical debt instrument that provides for
either the qualified floating rate or qualified inverse floating rate rather
than the fixed rate. Subsequent to converting the fixed rate into either a
qualified floating rate or a qualified inverse floating rate, the Floating Rate
Debt Security is then converted into an "equivalent" fixed rate debt instrument
in the manner described above.
 
     Once the Floating Rate Debt Security is converted into an "equivalent"
fixed rate debt instrument pursuant to the foregoing rules, the amount of OID
and qualified stated interest, if any, are determined for the "equivalent" fixed
rate debt instrument by applying the general OID rules to the "equivalent" fixed
rate debt instrument and a U.S. Holder of the Floating Rate Debt Security will
account for such OID and qualified stated interest as if the U.S. Holder held
the "equivalent" fixed rate debt instrument. In each accrual period, appropriate
adjustments will be made to the amount of qualified stated interest or OID
assumed to have been accrued or paid with respect to the "equivalent" fixed rate
debt instrument in the event that such amounts differ from the actual amount of
interest accrued or paid on the Floating Rate Debt Security during the accrual
period.
 
     If a Floating Rate Debt Security does not qualify as a "variable rate debt
instrument" under the OID Regulations, then the Floating Rate Debt Security
would be treated as a contingent payment debt obligation. Special United States
federal income tax considerations applicable to Floating Rate Debt Securities
that are treated as contingent payment debt obligations will be more fully
described in the applicable prospectus supplement.
 
     Short-Term Debt Securities.  In general, an individual or other cash basis
U.S. Holder of a short-term debt security is not required to accrue OID (as
specially defined below for the purposes of this paragraph and the immediately
following paragraph) for United States federal income tax purposes unless it
elects to do so (but may be required to include any stated interest in income as
the interest is received). Accrual basis U.S. Holders and certain other U.S.
Holders, including banks, regulated investment companies, dealers in securities,
common trust funds, U.S. Holders who hold debt securities as part of certain
identified hedging transactions, certain pass-thru entities and cash basis U.S.
Holders who so elect, are required to accrue OID on short-term debt securities
on either a straight-line basis or under the constant-yield method (based on
daily
 
                                       31
<PAGE>   54
 
compounding), at the election of the U.S. Holder. In the case of a U.S. Holder
not required and not electing to include OID in income currently, any gain
realized on the sale, exchange or retirement of the short-term debt security
will be ordinary income to the extent of the OID accrued on a straight-line
basis (unless an election is made to accrue the OID under the constant-yield
method) through the date of sale, exchange or retirement. U.S. Holders who are
not required and do not elect to accrue OID on short-term debt securities will
be required to defer deductions for interest on borrowings incurred or continued
to purchase or carry such short-term debt securities in an amount not exceeding
the deferred interest income until the deferred interest income is realized.
 
     For purposes of determining the amount of OID subject to these rules, all
interest payments on a short-term debt security, including stated interest, are
included in the short-term debt security's stated redemption price at maturity.
 
     Foreign Currency Discount Debt Securities.  OID for any accrual period on a
Discount debt security that is denominated in, or determined by reference to, a
foreign currency will be determined in the foreign currency and then translated
into U.S. dollars in the same manner as stated interest accrued by an accrual
basis U.S. Holder, as described above under "Payments of Interest -- Foreign
Currency Denominated Interest." Upon receipt of an amount attributable to OID
(whether in connection with a payment of interest or the sale or retirement of a
debt security), a U.S. Holder may recognize ordinary income or loss.
 
     MARKET DISCOUNT
 
     A debt security, other than a short-term debt security, will be treated as
purchased at a market discount (a "MARKET DISCOUNT DEBT SECURITY") if the debt
security's stated redemption price at maturity or, in the case of a Discount
Debt Security, the debt security's "revised issue price," exceeds the amount for
which the U.S. Holder purchased the debt security by at least 1/4 of 1 percent
of such debt security's stated redemption price at maturity or revised issue
price, respectively, multiplied by the number of complete years to the debt
security's maturity. If such excess is not sufficient to cause the debt security
to be a Market Discount Debt Security, then such excess constitutes "DE MINIMIS
MARKET DISCOUNT." The Code provides that, for these purposes, the "REVISED ISSUE
PRICE" of a debt security generally equals its issue price, increased by the
amount of any OID that has accrued on the debt security.
 
     Any gain recognized on the maturity or disposition of a Market Discount
Debt Security will be treated as ordinary income to the extent that such gain
does not exceed the accrued market discount on such debt security.
Alternatively, a U.S. Holder of a Market Discount Debt Security may elect to
include market discount in income currently over the life of the debt security.
Such an election shall apply to all debt instruments with market discount
acquired by the electing U.S. Holder on or after the first day of the first
taxable year to which the election applies. This election may not be revoked
without the consent of the IRS.
 
     Market discount on a Market Discount Debt Security will accrue on a
straight-line basis unless the U.S. Holder elects to accrue such market discount
on a constant-yield method. Such an election shall apply only to the debt
security with respect to which it is made and may not be revoked without the
consent of the IRS. A U.S. Holder of a Market Discount Debt Security that does
not elect to include market discount in income currently generally will be
required to defer deductions for interest on borrowings allocable to such
 
                                       32
<PAGE>   55
 
debt security in an amount not exceeding the accrued market discount on such
debt security until the earlier of the maturity or disposition of such debt
security.
 
     DEBT SECURITIES PURCHASED AT A PREMIUM
 
     A U.S. Holder that purchases a debt security for an amount in excess of its
principal amount, or in the case of a Discount Debt Security, its stated
redemption price at maturity, may elect to treat such excess as "amortizable
bond premium," in which case the amount required to be included in the U.S.
Holder's income each year with respect to interest on the debt security will be
reduced by the amount of amortizable bond premium allocable (based on the debt
security's yield to maturity) to such year. A U.S. Holder who makes such
election must reduce such Holder's tax basis in the debt security by the amount
of amortized premium. In the case of a debt security that is denominated in, or
determined by reference to a foreign currency, bond premium will be computed in
units of foreign currency, and amortizable bond premium will reduce interest
income in units of the foreign currency. At the time amortized bond premium
offsets interest income, exchange gain or loss (taxable as ordinary income or
loss) is realized measured by the difference between exchange rates at that time
and at the time of the acquisition of the debt securities. Any election to
amortize bond premium shall apply to all bonds (other than bonds the interest on
which is excludible from gross income) held by the U.S. Holder at the beginning
of the first taxable year to which the election applies or thereafter acquired
by the U.S. Holder, and is irrevocable without the consent of the IRS. See also
"Original Issue Discount -- Election to Treat All Interest as Original Issue
Discount."
 
     PURCHASE, SALE AND RETIREMENT OF THE DEBT SECURITIES
 
     A U.S. Holder's tax basis in a debt security will generally be its U.S.
dollar cost (as defined below), increased by the amount of any OID or market
discount included in the U.S. Holder's income with respect to the debt security
and the amount, if any, of income attributable to de minimis original issue
discount and de minimis market discount included in the U.S. Holder's income
with respect to the debt security, and reduced by (1) the amount of any payments
that are not qualified stated interest payments, and (2) the amount of any
amortizable bond premium applied to reduce interest on the debt security. The
U.S. dollar cost of a debt security purchased with a foreign currency will
generally be the U.S. dollar value of the purchase price on the date of purchase
or, in the case of debt securities traded on an established securities market,
as defined in the applicable Treasury Regulations, that are purchased by a cash
basis U.S. Holder (or an accrual basis U.S. Holder that so elects), on the
settlement date for the purchase.
 
     A U.S. Holder will generally recognize gain or loss on the sale or
retirement of a debt security equal to the difference between the amount
realized on the sale or retirement and the tax basis of the debt security. The
amount realized on a sale or retirement for an amount in foreign currency will
be the U.S. dollar value of such amount on the date of sale or retirement or, in
the case of debt securities traded on an established securities market, as
defined in the applicable Treasury Regulations, sold by a cash basis U.S. Holder
(or an accrual basis U.S. Holder that so elects), on the settlement date for the
sale. Except to the extent described above under "-- Original Issue Discount --
Short-Term Debt Securities" or "-- Market Discount" or described in the next
succeeding paragraph or attributable to accrued but unpaid interest, gain or
loss recognized on the sale or retirement of a debt security will be capital
gain or loss. Gain recognized on the disposition of a capital asset held by an
individual taxpayer for more than one year is
 
                                       33
<PAGE>   56
 
generally subject to a maximum rate of tax of 20%. U.S. Holders are urged to
consult their own tax advisors with respect to recently enacted capital gains
legislation.
 
     Gain or loss recognized by a U.S. Holder on the sale or retirement of a
debt security that is attributable to changes in exchange rates will be treated
as ordinary income or loss. However, exchange gain or loss is taken into account
only to the extent of total gain or loss realized on the transaction.
 
     EXCHANGE OF AMOUNTS IN OTHER THAN U.S. DOLLARS
 
     Foreign currency received as interest on a debt security or on the sale or
retirement of a debt security will have a tax basis equal to its U.S. dollar
value at the time such interest is received or at the time of such sale or
retirement. Foreign currency that is purchased will generally have a tax basis
equal to the U.S. dollar value of the foreign currency on the date of purchase.
Any gain or loss recognized on a sale or other disposition of foreign currency
(including its use to purchase debt securities or upon exchange for U.S.
dollars) will be ordinary income or loss.
 
     AMORTIZING DEBT SECURITIES
 
     The applicable prospectus supplement will contain a discussion of special
United States federal income tax rules applicable to debt securities that
provide for partial principal payments prior to stated maturity.
 
UNITED STATES ALIEN HOLDERS
 
     An alien individual who is neither a citizen nor a lawful permanent
resident of the United States may, subject to certain exceptions, be deemed to
be a resident of the United States for U.S. federal income tax purposes by
virtue of being present in the United States on at least 31 days in the calendar
year and for an aggregate of at least 183 days during a three-calendar-year
period ending in the current calendar year (counting for such purposes all of
the days present in the current year, one-third of the days present in the
immediately preceding year and one-sixth of the days present in the second
preceding year). Resident aliens are subject to United States federal income tax
as if they were United States citizens and residents. See "U.S. Holders" above.
 
     Under present United States federal income and estate tax law and subject
to the discussion of backup withholding below:
 
          (1) payments of principal, premium (if any) and interest (including
     OID) by us or any of our paying agents to any holder of a debt security who
     or which is a United States Alien Holder will not be subject to United
     States federal withholding tax (and, except as discussed in paragraph (4)
     below, will not generally be subject to U.S. federal income tax) if, in the
     case of premium (if any), interest or OID, (a) the beneficial owner of the
     debt security does not actually or constructively own 10% or more of the
     total combined voting power of all classes of our stock entitled to vote,
     (b) the beneficial owner of the debt security is not a controlled foreign
     corporation that is related to us through stock ownership, (c) the interest
     on the debt security is not contingent interest to which Section
     871(h)(4)(A) of the Code is applicable, and (d) either (i) the beneficial
     owner of the debt security certifies to us or our agent, under penalties of
     perjury, that it is not a U.S. Holder and provides its name and address or
     (ii) a securities clearing organization, bank or other financial
     institution that holds customers' securities in the ordinary course of its
     trade or business (a "FINANCIAL INSTITUTION") and holds the debt security
     certifies to us or our agent under
 
                                       34
<PAGE>   57
 
     penalties of perjury that such statement has been received from the
     beneficial owner by it or by a financial institution acting on behalf of
     the beneficial owner and furnishes the payor with a copy thereof;
 
          (2) a United States Alien Holder of a debt security will not be
     subject to United States federal withholding tax on any gain realized on
     the sale or exchange of a debt security;
 
          (3) a debt security held by an individual who at death is not a
     citizen or resident of the United States will not be includible in the
     individual's gross estate for purposes of the United States federal estate
     tax as a result of the individual's death if the individual did not
     actually or constructively own 10% or more of the total combined voting
     power of all classes of our stock entitled to vote, the income on the debt
     security would not have been effectively connected with a United States
     trade or business of the individual at the individual's death and, in the
     case of a debt security on which all or a portion of the interest payments
     are contingent interest to which Section 871(h)(4)(A) is applicable, to the
     extent that the value of such debt security is not allocable to such
     contingent interest;
 
          (4) if premium, interest or OID on a debt security of a United States
     Alien Holder is effectively connected with the conduct of a United States
     trade or business, then such holder, with respect to such premium, interest
     or OID, (a) will be exempt from United States withholding tax (upon such
     holder's delivery of a properly completed and periodically updated IRS Form
     4224 or successor form thereto), (b) will be subject to United States
     federal income tax in the same manner and at the same rates as if such
     holder were a U.S. Holder and (c) may be subject, if the United States
     Alien Holder is a corporation, to the "branch profits tax" at a 30% rate
     (which tax is generally imposed on a foreign corporation on the actual or
     deemed repatriation from the United States of earnings and profits
     attributable to income that is effectively connected with the conduct of a
     U.S. trade or business); and
 
          (5) a United States Alien Holder of a debt security will not be
     subject to United States federal income tax on any gain realized on the
     sale or exchange of a debt security unless (a) such gain is effectively
     connected with the conduct of a United States trade or business, in which
     case such holder will be subject to United States federal income tax on
     such gain in the same manner and at the same rates as if such holder were a
     U.S. Holder and such holder may be subject to the branch profits tax
     described in clause (4)(c) above, (b) subject to certain exceptions, the
     United States Alien Holder is an individual who holds the debt security as
     a capital asset and is present in the United States for 183 days or more in
     the taxable year of the disposition, or (c) the United States Alien Holder
     is subject to tax pursuant to provisions of United States tax law
     applicable to certain United States expatriates (including certain former
     citizens or residents of the United States).
 
     The payment of premium, interest or OID that qualifies for neither the
withholding exemption set forth in paragraph (1) above nor the withholding
exemption set forth in paragraph (4) above will be subject to U.S. federal
withholding tax at the rate of 30%, unless a U.S. income tax treaty applies to
reduce or eliminate such withholding. To claim the benefit of a tax treaty, a
United States Alien Holder must deliver a properly completed and periodically
updated IRS Form 1001 or successor form.
 
     Treasury regulations that will be effective with respect to payments made
after December 31, 1999 (the "WITHHOLDING REGULATIONS"), will provide
alternative methods for
 
                                       35
<PAGE>   58
 
satisfying the certification requirements described in clause (1)(d) above. The
Withholding Regulations also will require, in the case of debt securities held
by a foreign partnership, that (x) such certification requirements be satisfied
by the partners and (y) the partnership provide certain information, including
its U.S. taxpayer identification number. A look-through rule will apply in the
case of tiered partnerships. Under the Withholding Regulations, a United States
Alien Holder who is claiming the benefits of a treaty may be required to obtain
a U.S. taxpayer identification number, which may require providing certain
documentary evidence issued by a foreign governmental authority to prove
residence in the foreign country. Certain special procedures are provided in the
Withholding Regulations for payments through qualified intermediaries.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
     U.S. HOLDERS
 
     In general, information reporting requirements will apply to payments of
principal, any premium and interest on a debt security to non-corporate U.S.
Holders, the payment of the proceeds of the sale of a debt security before
maturity within the United States to non-corporate U.S. Holders and the accrual
of OID on a Discount Debt Security with respect to non-corporate U.S. Holders,
and "backup withholding" at a rate of 31% will apply to such payments and to
payments of OID if the U.S. Holder fails to provide an accurate taxpayer
identification number or to report all interest and dividends required to be
shown on such U.S. Holder's federal income tax returns. Holders should consult
their tax advisors regarding their qualification for exemption from backup
withholding and the procedure for obtaining such an exemption if applicable. The
amount of any backup withholding from a payment to a U.S. Holder will be allowed
as a credit against such U.S. Holder's U.S. federal income tax liability and may
entitle such U.S. Holder to a refund, provided that the required information is
furnished to the IRS.
 
     UNITED STATES ALIEN HOLDERS
 
     Backup withholding will generally not apply to payments of principal,
premium (if any) and interest (including OID) made by us or a paying agent to a
United States Alien Holder on a debt security if the certification described in
clause (1)(d) under "-- United States Alien Holders" above is received, provided
that the payor does not have actual knowledge that the holder is a United States
person. We may be required to report annually to the IRS and to each United
States Alien Holder the amount of interest paid to, and the tax withheld, if
any, with respect to such Holder. These information reporting requirements apply
regardless of whether withholding is required. Copies of the information returns
reporting such withholding may also be made available to the tax authorities in
the country in which the United States Alien Holder resides under the provisions
of an applicable income tax treaty.
 
     Payments of the proceeds from the sale by a United States Alien Holder of a
debt security made to or through a foreign office of a broker will not be
subject to information reporting or backup withholding, except that if the
broker is a United States person, a controlled foreign corporation for United
States tax purposes, a foreign person 50% or more of whose gross income is
effectively connected with a United States trade or business for a specified
three-year period or, effective after December 31, 1999, in certain other cases
specified under the Withholding Regulations, information reporting may apply to
such payments. Payments of the proceeds from the sale of a debt security to or
through the United States office of a broker is subject to information reporting
and backup withholding
 
                                       36
<PAGE>   59
 
unless the holder or beneficial owner certifies as to its non-United States
status or otherwise establishes an exemption from information reporting and
backup withholding.
 
     THE SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES SET FORTH ABOVE IS FOR
GENERAL INFORMATION ONLY. YOU SHOULD CONSULT YOUR OWN PERSONAL TAX ADVISORS AS
TO THE PARTICULAR TAX CONSEQUENCES OF THE DEBT SECURITIES TO YOU, INCLUDING THE
APPLICABILITY AND EFFECT OF STATE, FEDERAL, LOCAL, FOREIGN AND OTHER TAX LAWS
AND POSSIBLE CHANGES IN TAX LAW.
 
                              PLAN OF DISTRIBUTION
 
     We may sell the debt securities in and/or outside the United States: (1)
through underwriters or dealers; (2) directly to a limited number of purchasers
or to a single purchaser; or (3) through agents. The applicable prospectus
supplement with respect to the debt securities will set forth the terms of the
offering of the debt securities, including the name or names of any underwriters
or agents, if any, the purchase price of the debt securities and the proceeds to
us from such sale. In addition, the applicable prospectus supplement will set
forth any delayed delivery arrangements, any underwriting discounts and other
items constituting underwriters' compensation, any initial public offering price
and any discounts or concessions allowed or re-allowed or paid to dealers. Any
initial public offering price and any discount or concessions allowed or
reallowed or paid to dealers may be changed from time to time.
 
     If underwriters are used in the sale, the debt 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 a fixed public
offering price or at varying prices determined at the time of sale. The debt
securities may be offered to the public either through underwriting syndicates
represented by one or more managing underwriters or directly by one or more
firms acting as underwriters. The underwriter or underwriters with respect to a
particular underwritten offering of debt securities will be named in the
prospectus supplement relating to such offering and, if an underwriting
syndicate is used, the managing underwriter or underwriters will be set forth on
the cover of such prospectus supplement. Unless otherwise set forth in the
prospectus supplement relating thereto, the obligations of the underwriters to
purchase the offered debt securities will be subject to conditions precedent and
the underwriters will be obligated to purchase all the offered debt securities
if any are purchased.
 
     If dealers are used in the sale of debt securities in respect of which this
prospectus is delivered, we will sell such debt securities to the dealers as
principals. The dealers may then resell such debt securities to the public at
varying prices to be determined by such dealers at the time of resale. The names
of the dealers and the terms of the transaction will be set forth in the
prospectus supplement relating thereto.
 
     The debt securities may be sold through agents we designate from time to
time. Any agent involved in the offer or sale of the debt securities in respect
to which this prospectus is delivered will be named, and any commissions payable
by us to such agent will be set forth, in the prospectus supplement relating
thereto. Unless otherwise indicated in the prospectus supplement, any such agent
will be acting on a best efforts basis for the period of its appointment.
 
                                       37
<PAGE>   60
 
     We may sell the debt securities directly to institutional investors or
others, who may be deemed to be underwriters within the meaning of the
Securities Act of 1933, as amended (the "SECURITIES ACT"), with respect to any
resale thereof. The terms of any such sales, including the terms of any bidding
or auction process, will be described in the prospectus supplement relating
thereto.
 
     Agents, dealers and underwriters may be entitled under agreements entered
into with us to indemnification by us against certain civil liabilities,
including liabilities under the Securities Act, or to contribution with respect
to payments which such agents, dealers or underwriters may be required to make
in respect thereof. Agents, dealers and underwriters may be our customers,
engage in transactions with us, or perform services for us in the ordinary
course of business.
 
     In connection with an offering, certain persons participating in such
offering may engage in transactions that stabilize, maintain or otherwise affect
the price of the debt securities. Specifically, such persons may overallot such
offering, creating a syndicate short position. In addition, such persons may bid
for, and purchase, the debt securities in the open market to cover syndicate
shorts or to stabilize the price of the debt securities. Finally, such persons
may reclaim selling concessions allowed for distributing the debt securities in
an offering, if such persons repurchase previously distributed debt securities
in syndicate covering transactions, in stabilization transactions or otherwise.
Any of these activities may stabilize or maintain the market price of the debt
securities above independent market levels. Such persons are not required to
engage in these activities, and may end any of these activities at any time. The
debt securities may or may not be listed on a national securities exchange. We
cannot assure you as to the future liquidity of the trading market, if any, for
any debt securities issued.
 
                                 LEGAL MATTERS
 
     Certain legal matters in connection with the debt securities offered hereby
will be passed upon for us by our counsel Wachtell, Lipton, Rosen & Katz, New
York, New York and for any underwriters or agents by Shearman & Sterling, New
York, New York.
