                 BorgWarner Inc. and Consolidated Subsidiaries'
                              Financial Statements


The financial statements of BorgWarner Inc. and Consolidated Subsidiaries
("Company") have been prepared in accordance with the instructions to Form 10-Q
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The
statements are unaudited but include all adjustments, consisting only of
recurring items, except as noted, which the Company considers necessary for a
fair presentation of the information set forth herein. The results of operations
for the three months ended March 31, 2001 are not necessarily indicative of the
results to be expected for the entire year. The following financial statements
and Management's Discussion and Analysis of Financial Condition and Results of
Operations should be read in conjunction with the Company's Annual Report on
Form 10-K for the fiscal year ended December 31, 2000.

This Form 10-Q/A has been filed for the sole purpose of correcting two
typographical errors. On page 5, in the Consolidated Statements of Cash Flows
(Unaudited), the caption "Net cash provided by operating activities" is $1.9
million. In the Form 10-Q filed on May 14, 2001, a typographical error caused
the amount to be reported as $(1.9) million. On page 11, in Note 10, the correct
date is April 2001.

(4)  The Company's provisions for income taxes for the three months ended March
     31, 2001 and 2000 are based upon estimated annual tax rates for the year
     applied to federal, state and foreign income. The effective rate differed
     from the U.S. statutory rate primarily due to a)state income taxes,
     b)foreign rates which differ from those in the U.S., c)realization of
     certain business tax credits, including foreign tax credits and research
     and development credits and d)other non-deductible expenses, such as
     goodwill.

     The Company maintains a $350 million revolving credit facility. At March
     31, 2001, $15.0 million of borrowings under the facility were outstanding
     in addition to $6.5 million of obligations under standby letters of credit.
     At December 31, 2000, the facility was unused. The facility is available
     through July, 2005.

     The credit agreement contains numerous financial and operating covenants
     including, among others, covenants requiring the Company to maintain
     certain financial ratios and restricting its ability to incur additional
     foreign indebtedness.

(6)  The Company and certain of its 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 ("PRPs") at various hazardous waste disposal sites under the
     Comprehensive



                                      -7-


   9


     Environmental Response, Compensation and Liability Act ("Superfund") and
     equivalent state laws and, as such, may presently be liable for the cost of
     clean-up and other remedial activities at 42 such sites. Responsibility for
     clean-up and other remedial activities at a Superfund site is typically
     shared among PRPs based on an allocation formula.

     Based on information available to the Company, which in most cases,
     includes: an estimate of allocation of liability among PRPs; the
     probability that other PRPs, many of whom are large, solvent public
     companies, will fully pay the cost apportioned to them; currently available
     information from PRPs and/or federal or state environmental agencies
     concerning the scope of contamination and estimated remediation costs;
     remediation alternatives; estimated legal fees; and other factors, the
     Company has established a reserve for indicated environmental liabilities
     with a balance at March 31, 2001 of approximately $21.6 million. The
     Company expects this amount to be expended over the next three to five
     years.

     BorgWarner believes that none of these matters, individually or in the
     aggregate, will have a material adverse effect on its financial condition
     or future operating results, generally either because estimates of the
     maximum potential liability at a site are not large or because liability
     will be shared with other PRPs, although no assurance can be given with
     respect to the ultimate outcome of any such matter.

     In connection with the sale of Kuhlman Electric Corporation, the Company
     agreed to indemnify the buyer and Kuhlman Electric for certain
     environmental liabilities relating to the past operations of Kuhlman
     Electric. During 2000, Kuhlman Electric notified the Company that it
     discovered potential environmental contamination at its Crystals Springs,
     Mississippi plant while undertaking an expansion of the plant.

     The Company has been working with the Mississippi Department of
     Environmental Quality ("MDEQ") and Kuhlman Electric to investigate the
     extent of the contamination. To date, the investigation has revealed the
     presence of PCBs in portions of the soil at the plant and neighboring areas
     and the Company has cleaned several neighboring properties with MDEQ
     oversight. The Company has filed a lawsuit against Kuhlman Electric seeking
     a declaration of the scope of BorgWarner's contractual indemnity. As the
     investigation is in its early stages, and the court has not yet ruled on
     the lawsuit, the Company cannot now estimate the potential liability
     associated with this matter.


(7)  Comprehensive income is a measurement of all changes in stockholders'
     equity that result from transactions and other economic events other than
     transactions with stockholders. For the Company, this includes foreign
     currency translation adjustments, changes in minimum pension liability
     adjustments and net earnings. The amounts presented as other comprehensive
     income, net of related taxes, are added to net income which results in
     comprehensive income.

     Divested operations includes: 1) the fuel systems business which was

(9)  Restructuring and other non-recurring charges totaling $62.9 million
     pre-tax were incurred in the second half of 2000 in response to
     deteriorating market conditions. The charges included the rationalization
     and integration of certain businesses and actions taken to bring costs in
     line with vehicle production slowdowns in major customer product lines.

     Of the $62.9 million in pretax charges, $47.3 million represents non-cash
     charges. Approximately $4.4 million was spent in 2000 and $8.1 million was
     spent during the three months ended March 31, 2001. The remaining $3.1
     million is expected to be spent in the remainder of 2001. We expect to fund
     the total cash outlay with cash flow from operations. The actions taken are
     expected to generate approximately $19 million in annualized savings,
     primarily from lower salaries and benefit costs and reduced depreciation
     charges, beginning in 2001. These savings are expected to be more than
     offset by the impact of lower revenue from the deterioration in the
     automotive and heavy-duty truck markets.

     Components of the restructuring and other non-recurring charges are
     detailed in the following table and discussed further below.

                                                                    Balance at

     Severance and other benefit costs relate to the reduction of approximately
     220 employees from the workforce. The reductions affect each of our
     operating segments, apart from TorqTransfer Systems, across each of our
     geographical areas, and across each major functional area, including
     production and selling and administrative positions. As of March 31, 2001,
     approximately $6.7 million had been paid for severance and other benefits
     for 103 terminated employees. The remaining reductions and cash payments
     should be complete by the end of 2001.

     Asset write-downs primarily consist of the write-off of impaired assets
     that will no longer be used in production as a result of the industry
     downturn. Such assets have been taken out of production and are being
     disposed.

     Loss on anticipated sale of business is related to the fuel systems
     business, which is currently being reported as an investment in businesses
     held for sale on the Consolidated Balance Sheet. Fuel systems produces
     metal tanks for the heavy-duty truck market in North America and does not
     fit the Company's strategic focus on powertrain technology. In April 2000,
     the Company announced its intention to sell this non-core business, which
     was acquired as part of the vehicle products business of Kuhlman
     Corporation in March 1999. With the deterioration of the North American
     heavy-duty truck market in the second half of 2000, the value of this
     business has significantly decreased, creating the $35.2 million loss. As
     discussed in Note 10, in April 2001 the Company completed its sale of the
     fuel systems business.

     Other exit costs and non-recurring charges are primarily non-employee
     related exit costs incurred to close certain non-production facilities we
     no longer need.

(10) In April 2001, the Company completed the sale of its fuel systems business
     to an investor group led by TMB Industries, a private equity group. Terms
     of the transaction do not have a significant impact on the Company's
     results of operations, financial condition or cash flows. Additionally, the
     net gain or loss on the sale is expected to be immaterial.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

INTRODUCTION

BorgWarner Inc. (the "Company") is a leading global supplier of highly
engineered systems and components for powertrain applications. Its products are
manufactured and sold worldwide, primarily to original equipment manufacturers
("OEMs") of passenger cars, sport-utility vehicles, trucks, commercial
transportation products and industrial equipment. The Company operates
manufacturing facilities serving customers in the Americas, Europe and Asia, and
is an original equipment supplier to every major OEM in the world.

RESULTS OF OPERATIONS

The Company's products fall into five reportable operating segments: Air/Fluid
Systems, Cooling Systems, Morse TEC, TorqTransfer Systems and Transmission
Systems. The following tables present net sales and earnings before interest and
taxes ("EBIT") by segment for the three months ended March 31, 2001 and 2000 in
millions of dollars.

Consolidated sales for the three months ended March 31, 2001 totaled $606.8
million, a 16.9% decline over the first quarter of 2000. For the Company's
ongoing businesses, the decline was 14.5%. This decline was in line with the
North American automotive market, which experienced production decreases of 21%.
Geographically, the sales decline was most significant in North America with
lesser amounts coming from Asia and Europe. Of the overall sales decline, $14
million was the result of weaker currencies in both Europe and Japan. The Morse
TEC and Transmission Systems groups are the most affected by European and Asian
currency fluctuations. Income declined from $41.0 million to $21.1 million, a
48.5% reduction. In addition to the falloff in volumes, there are certain fixed
costs in the statement of operations such as depreciation, amortization, and
interest that cause the percentage decrease in income to be greater than the
percentage decrease in sales. Despite the almost $20 million decline in income,
the Company was able to keep debt levels at about the same as December 31, 2000
through a combination of strong working capital management and control of
capital spending. This effort occurred across all of the Company's business
groups.

The Air/Fluid Systems business was off almost 27% compared to 2000 and EBIT
declined by $12.6 million or 80.8%. Production declines at Chrysler, a major
customer of this group, were primarily responsible for the overall sales
falloff. In addition, the group experienced an unusually high level of emission
related business in the first quarter of 2000 that was non-recurring.

The Cooling Systems business suffered from the continued decline in the
commercial vehicle arena, where volumes in North America have fallen from an
annual rate in excess of 300,000 units for heavy truck, to just above 100,000.
First quarter 2001 sales and EBIT were down 27.2% and 81.8% from first quarter
2000, respectively. The group was also negatively impacted by a model
changeover, which eliminated one application. This business is expected to be
replaced, but not until the end of 2001.

The Morse Tec group had a sales decline of 6.0%. Consistent with the Company's
other business groups, Morse TEC was affected by the downturn in North America,
especially due to the lower volumes for Chrysler and General Motors front-wheel
drive cars and for North American four-wheel drive applications. A softer
commercial market in North America, which translated into lower turbocharger
sales, also affected the group. The European portion of the business continued
to be strong, particularly turbochargers and engine timing systems. However, the
weakness in European currencies mitigated that growth. EBIT declined 16.8% due
to the previously mentioned lower volumes and a change in mix between chain
products and turbocharger products.

The TorqTransfer Systems business experienced a 14.9% sales decrease and a $6.4
million EBIT decline. Most of the sales decline related to Ford, its largest
customer. Reductions in Ford light truck and SUV volumes was exacerbated by the
careful launch of the new Ford Explorer, on which BorgWarner has substantial
content. Substantially all of the earnings decline is attributable to the volume
declines, but the group also gave customers some price reductions. This business
has a relatively high fixed cost structure, which causes larger swings in
earnings when volume changes.

Transmission Systems had a 10.0% sales decline and 18.4% decline in EBIT.
Declines in North American volumes were partially offset by sales increases in
Europe and Asia. Installation rates for automated transmissions continued to
grow in both Europe and Asia, helping to increase our volumes in those regions.
This group has the widest range of OEM customers, and the production declines in
North America were reflected in its sales performance.



                                      -13-

Because of significant cost cutting efforts undertaken in late 2000 and early
2001, the group was able to limit the decrease in EBIT to 18.4%. This group was
quick to respond to the softening North American marketplace and took costs out
of its overhead structure to be more in line with current business levels.

Divested operations included the Company's fuel systems business, which was sold
in April 2001 and its HVAC business, which was sold in December 2000. The sale
of the fuel systems business will be recorded in the second quarter of 2001. The
operating results of the fuel systems business were not material to the
Company's first quarter 2001 results. Additionally, the net gain or loss on the
sale is expected to be immaterial.

Consolidated gross margin for the first quarter of 2001, including depreciation,
was 18.0%, down 3 points from the first quarter of 2000. The gross margin
decline was the result of reduced volumes. Offsetting this is a reduction in
selling, general and administrative expenses, which are down $7.9 million. The
decline is the result of initiatives begun in late 2000 in response to the
slowdown in the North American market. The selling, general and administrative
category includes substantially all the Company's spending on research and
development. For the first quarter of 2001, R & D spending totaled $27.4
million, which is up to 4.5% of sales versus $29.7 million, or 4.1% of sales.
Spending at this level demonstrates the Company's ongoing commitment to new
product development, even in light of the industry downturn. The Company will
continue to monitor its research and development spending to balance short-term
affordability issues with the need to continually update and replenish its
product offering.

Goodwill amortization declined slightly from 2000 due to goodwill related to
divested businesses. Interest expense was down by $3.1 million as a result of
debt reductions throughout 2000 and lower interest rates. The Company is not as
sensitive to interest rate fluctuation, because 72% of its debt has fixed
interest rates. Affiliate earnings and other income rose $1.0 million,
principally due to increases at the Company's 50% owned Japanese affiliate,
NSK-Warner. BorgWarner's share of NSK-Warner's net earnings totaled $4.0 million
in the first quarter of 2001 and $3.4 million in the first quarter of 2000.
Because of the weakness of the Yen, the increase was even greater in local
currency.

The Company's income tax provision is based on estimated annual rates for the
year in the various jurisdictions in which the Company operates. The 37% tax
rate for 2001 varies from standard federal and state rates due to the
realization of certain R&D and foreign tax credits, foreign rates that differ
from U.S. rates and the effect of non-deductible items, such as goodwill. The
Company expects tax rates for 2001 to be in the 37 to 38% range, prior to any
change necessitated by the proposed new accounting standard related to business
combinations.

Net income was $21.1 million for the first quarter, or $0.80 per share, a
decline of 48.5% over the previous year quarter. Shares outstanding decreased
slightly due to share repurchases since the first quarter of 2000. Net income
was 3.5% of sales versus 5.6% last year. Had European and Asian currency
exchange rates been unchanged from last year, net income would have been $0.05
higher for the first quarter of 2001.

For the remainder of 2001, the Company remains concerned about production rates,
particularly in North America. If production stays at current levels, second and
third quarter sales and earnings will be unfavorable compared



                                      -14-


   16


with 2000. This holds true for both the light vehicle market and the heavy-duty
truck market. It would not be until the fourth quarter that market conditions
would be similar year over year. As a result, the Company is being very cautious
in its capital investment plans and is prepared to take additional operating
actions, beyond those taken in the third and fourth quarters of 2000, to keep
its operating costs in line with the level of production volumes. Despite these
issues, the Company maintains a positive long-term outlook for its business and
is committed to ongoing strategic investments in capital and new product
development to enhance its product leadership strategy.

FINANCIAL CONDITION AND LIQUIDITY

In the first quarter BorgWarner's debt was substantially unchanged from year-end
2000, increasing by only $0.3 million. The debt increase was comprised of $4.0
million for dividends offset by $2.3 million in proceeds from stock options
exercised and a $1.4 million inflow from all other activities including
operations and capital expenditures. The $1.4 million was realized despite the
$20 million decline in net earnings and was the result of controlling the
increase in working capital and exercising caution with respect to capital
spending. Working capital increased by $45.4 million, compared with $44.9
million last year. Capital spending was held to $17.2 million compared with
$28.3 million last year. The working capital increase is in part a function of
activity in the last month of the quarter, as receivable balances increase with
the increase in March business. Capital spending remains an area of focus, as
the Company intends to be very careful in making major investments too far in
advance of a recovery in its markets. The Company still expects to spend less
than $150 million on capital in 2001, but this level is subject to ongoing
review based on market conditions. Spending will be a function of the timing of
new programs for customers. The Company expects that over 70% of its capital
spending will be for new and expanded product programs, with the remainder going
to cost reduction and productivity enhancement programs and the Company's new
Powertrain Technical Center.

The net increase in debt of $0.3 million was composed of net increases in
borrowings of $7.0 million and a $6.7 million decrease in the dollar value of
foreign borrowings. Both European and Asian currencies declined versus year-end
2000, causing the dollar value of foreign denominated borrowings to decline. The
Company has a policy of borrowing in the geographies in which it operates to
match the investment in these geographies.

As of March 31,2001 and December 31,2000, the Company had sold $150 million of
receivables under a $153 million Receivables Transfer Agreement for face value
without recourse.

Other balance sheet changes of significance included fixed assets, which
declined $15.6 million and goodwill, which declined $11.7 million. The fixed
asset decline is the result of a $9.8 million excess of depreciation over
capital spending and a $5.8 million decline due to foreign currency exchange
rate changes. The goodwill decline is principally due to goodwill amortization.

The Company believes that the combination of cash from operations and credit
from existing credit facilities will be sufficient to satisfy its cash needs for
the current level of operations and planned operations for the remainder of
2001, despite the industry downturn. The Company plans to continue to manage its
operations to minimize the need for net new investments until it becomes more
evident that the Company's product markets are recovering.

OTHER MATTERS

Sale of fuel systems
In April 2001, the Company sold its fuel systems business. This business was
acquired as part of the acquisition of Kuhlman Corporation in March 1999. After
evaluating its business, metal fuel tanks and related components for the heavy-
and medium-duty truck markets, the Company determined this business to be
non-core. The proceeds will be used for general corporate purposes, including
the repayment of indebtedness. This business has been included in the divested
operations category for business segment reporting since April 2000. The net
gain or loss on the sale is expected to be immaterial.

Litigation
As discussed more fully in Note 6 to the Consolidated Financial Statements,
various claims and suits seeking money damages arising in the ordinary course of
business and involving environmental liabilities have been filed against the
Company. In each of these cases, the Company believes it has a defendable
position and has made adequate provisions to protect the Company from material
losses. The Company believes that it has established adequate provisions for
litigation liabilities in its financial statements in accordance with generally
accepted accounting principles.

In connection with the sale of Kuhlman Electric Corporation, the Company agreed
to indemnify the buyer and Kuhlman Electric for certain environmental
liabilities relating to the past operations of Kuhlman Electric. During 2000,
Kuhlman Electric notified the Company that it discovered potential environmental
contamination at its Crystal Springs, Mississippi plant while undertaking an
expansion of the plant.

The Company has been working with the Mississippi Department of Environmental
Quality ("MDEQ") and Kuhlman Electric to investigate the extent of the
contamination. To date, the investigation has revealed the presence of PCBs in
portions of the soil at the plant and neighboring areas and the Company has
cleaned several neighboring properties with MDEQ oversight. The Company has
filed a lawsuit against Kuhlman Electric seeking a declaration of the scope of
BorgWarner's contractual indemnity. As the investigation is in its early stages,
and the court has not yet ruled on the lawsuit, the Company cannot now estimate
the potential liability associated with this matter.

Dividends
On April 23, 2001, the Company declared a $0.15 per share dividend to be paid on
May 15, 2001 to shareholders of record as of May 1, 2001.

New Accounting Pronouncements
On January 1, 2001, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging
Activities," as amended. This statement standardizes the accounting for
derivative instruments by requiring that an entity recognize all derivatives as
assets or liabilities in the statement of financial position and measure them at
fair value. When certain criteria are met, it also provides for matching the
timing of gain or loss recognition on the derivative hedging instrument with the
recognition of (a) the changes in the fair value or cash flows of the hedged
asset or liability attributable to the hedged risk or (b) the earnings effect of
the hedged forecasted transaction. The company has a small number of derivative
instruments. Application of SFAS 133 is not material to results of operations,
financial condition or cash flows.

In December 1999, the Securities and Exchange Commission issued Staff



                                      -16-

Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial
Statements." This SAB provides guidance on the recognition, presentation and
disclosure of revenue in the financial statements of public companies. The
adoption of SAB No. 101 has not had a material effect on the Company's financial
position or results of operations.

In September 2000, the Financial Accounting Standards Board issued SFAS No. 140,
Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities which the Company must adopt for all applicable transactions
occurring after March 31, 2001. The Company is currently assessing the impact of
this standard on its results of operations, financial condition and cash flows.

                                     PART II





Item 1.   Legal Proceedings

          On November 20, 2000, the Company filed a patent infringement lawsuit
          against New Venture Gear, Inc. ("NVG") in U.S. District Court
          (Northern District of Illinois, Eastern Division) with regard to
          certain transfer cases manufactured by NVG. The suit requests
          unspecified monetary damages as well as a permanent injunction against
          the production of infringing transfer cases by NVG.

          In response to this lawsuit, on March 20, 2001, NVG filed a patent
          infringement lawsuit against the Company in U.S. District Court
          (Eastern District of Michigan, Southern Division) with regard to
          certain transfer cases manufactured by the Company. The suit requests
          unspecified monetary damages as well as a permanent injunction against
          the production of allegedly infringing transfer cases by the Company.
          The Company had considered the NVG patents being asserted against it
          before the filing of the suit against NVG, and again after NVG filed
          its lawsuit. The Company believes the counter-suit filed by NVG is
          without merit and intends to defend it vigorously. The Company does
          not believe that this lawsuit will have a material effect on its
          financial position, results of operations or liquidity, although no
          assurance can be given with respect to the ultimate outcome.
