                 WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
            FOR THE QUARTERLY PERIOD ENDED MARCH 31, 2003 (UNAUDITED)



1.       BUSINESS

Westinghouse Air Brake Technologies Corporation (the "Company", "Wabtec") is one
of North America's largest manufacturers of value-added equipment for
locomotives, railway freight cars and passenger transit vehicles. Our major
products are intended to enhance safety, improve productivity and reduce
maintenance costs for our customers. Product offerings include brakes for
locomotives, freight cars and passenger transit vehicles, electronic controls
and monitors, heat exchangers and cooling systems, switcher and commuter
locomotives, couplers, door systems and draft gears. The Company aggressively
pursues technological advances with respect to both new product development and
product enhancements.

2.        ACCOUNTING POLICIES

BASIS OF PRESENTATION The unaudited condensed consolidated interim financial
statements have been prepared in accordance with generally accepted accounting
principles and the rules and regulations of the Securities and Exchange
Commission and include the accounts of Wabtec and its majority owned
subsidiaries. These condensed interim financial statements do not include all of
the information and footnotes required for complete financial statements. In
management's opinion, these financial statements reflect all adjustments of a
normal, recurring nature necessary for a fair presentation of the results for
the interim periods presented. Results for these interim periods are not
necessarily indicative of results to be expected for the full year.

The Company operates on a four-four-five week accounting quarter, and
accordingly, the quarters end on or about March 31, June 30, September 30 and
December 31.

The notes included herein should be read in conjunction with the audited
consolidated financial statements included in Wabtec's Annual Report on Form
10-K for the year ended December 31, 2002. The December 31, 2002 information has
been derived from the Company's December 31, 2002 Annual Report on Form 10-K.

REVENUE RECOGNITION Revenue is recognized in accordance with Staff Accounting
Bulletin (SAB) 101, "Revenue Recognition in Financial Statements." Wabtec
recognizes revenue upon the passage of title, ownership and risk of loss to the
customer.

The Company recognizes revenues on long-term contracts based on the percentage
of completion method of accounting. Contract revenues and cost estimates are
reviewed and revised quarterly, at a minimum, and adjustments are reflected in
the accounting period as known. Provisions are made for estimated losses on
uncompleted contracts as known, if necessary.

USE OF ESTIMATES The preparation of financial statements in conformity with
accounting principles generally accepted in the United States requires the
Company to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the date of the financial statements and reported
amounts of revenues and expenses during the reporting period. Actual amounts
could differ from the estimates. On an ongoing basis, management reviews its
estimates based on currently available information. Changes in facts and
circumstances may result in revised estimates.

FINANCIAL DERIVATIVES AND HEDGES ACTIVITY The Company has adopted Statement of
Financial Accounting Standards ("SFAS") No. 133, as amended by SFAS 138,
"Accounting for Derivative Instruments and Hedging Activities" effective January
1, 2001. In the application, the Company has concluded its interest rate swap
contracts qualify for "special cash flow hedge accounting" which permit
recording the fair value of the swap and corresponding adjustment to other
comprehensive income (loss) on the balance sheet.

RECENT ACCOUNTING PRONOUNCEMENTS In April 2002, SFAS No. 145, "Rescission of
FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and
Technical Corrections", was issued. The Statement updates, clarifies and
simplifies existing accounting pronouncements. While the technical corrections
to existing pronouncements are not substantive in nature, in some instances,
they may change accounting practice. The provisions of this standard related to
SFAS No. 13 are effective for transactions occurring after May 15, 2002. All
other provisions of this standard must be applied for financial statements
issued on or after May 15, 2002. The Company has not completed the process of
evaluating the impact that will result from adopting it.

In June 2002, the Financial Accounting Standards Board issued SFAS No. 146,
"Accounting for Costs Associated with Exit or Disposal Activities." SFAS No. 146
nullifies Emerging Issues Task Force Issue No. 94-3, "Liability Recognition for
Certain Employee Termination Benefits and Other Costs to Exit an Activity,"
under which a liability for an exit cost was recognized at the date of an
entity's commitment to an exit plan. SFAS No. 146 requires that a liability for
a cost associated with an exit or disposal activity be recognized at fair value
when the liability is incurred. The provisions of this statement are effective
for exit or disposal activities that are initiated after December 31, 2002. The
Company has not had nor anticipates any action that would be covered under this
statement.



                                       6


STOCK BASED COMPENSATION PLANS In December 2002, the Financial Accounting
Standards Board issued SFAS No. 148, "Accounting for Stock-Based Compensation,"
to provide alternate methods of transition to SFAS No. 123's fair value method
of accounting for stock-based compensation. While the Statement does not amend
SFAS No. 123 to require companies to account for employee stock options using
the fair value method, the disclosure provisions of the Statement are applicable
to all companies with stock-based compensation. The provisions of this standard
are effective for fiscal years ending after December 15, 2002.

The Company applies APB 25 and related interpretations in accounting for its
stock-based compensation plans. Accordingly, no compensation expense has been
recognized under these plans. Had compensation expense for these plans been
determined based on the fair value at the grant dates for awards, the Company's
net income and earnings per share would be as set forth in the following table.
For purposes of pro forma disclosures, the estimated fair value is amortized to
expense over the options' vesting period.

   Pro forma                                  0.10             (1.37)



Since compensation expense associated with option grants would be recognized
over the vesting period, the initial impact of applying SFAS No. 123 on pro
forma net income is not representative of the potential impact on pro forma net
income in future years. In each subsequent year, pro forma compensation expense
would include the effect of recognizing a portion of compensation expense from
multiple awards.

For purposes of presenting pro forma results, the fair value of each option
grant is estimated on the date of grant using the Black-Scholes option-pricing
model with the following weighted-average assumptions:

The Black-Scholes option valuation model was developed for use in estimating
fair value of traded options, which are significantly different than employee
stock options. Although this valuation model is an acceptable method for use in
presenting pro forma information, because of the differences in traded options
and employee stock options, the Black-Scholes model does not necessarily provide
a single measure of the fair value of employee stock options.

OTHER COMPREHENSIVE INCOME (LOSS) Comprehensive income (loss) is defined as net
income and all nonowner changes in shareholders' equity. The Company's
accumulated other comprehensive income (loss) consists of foreign currency
translation adjustments, unrealized gains and losses on derivatives designated
and qualified as cash flow hedges and pension related adjustments. Total
comprehensive income (loss) for the three months ended March 31 was:

3.       DISCONTINUED OPERATIONS

In the fourth quarter of 2001, the Company decided to exit some small, non-core
businesses. One of these businesses was sold in the first quarter of 2002, and
the other is still being marketed for sale. In accordance with SFAS 144, the
operating results of these businesses have been classified as discontinued
operations for all years presented and are summarized for the three months ended
March 31, as follows:

    Total inventory                    $91,752        $88,470
- ---------------------------------------------------------------


5.   INTANGIBLES

The Company has adopted SFAS No. 142, "Goodwill and Other Intangible Assets"
effective January 1, 2002. Under its provisions, all goodwill and other
intangible assets with indefinite lives are no longer amortized under a
straight-line basis over the assets estimated useful life. Instead, they are
subject to periodic assessments for impairment by applying a fair-value based
test. As a result of the adoption of SFAS 142 during 2002, the Company wrote
down the carrying value of goodwill by $90 million ($83.2 million for the
freight group and $6.8 million for the transit group), resulting in a non-cash
after-tax charge of $61.7 million. The fair value of these reporting units was
determined using a combination of discounted cash flow analysis and market
multiples based upon historical and projected financial information. Goodwill
still remaining on the balance sheet is $109.5 million.

As of March 31, 2003 and December 31, 2002, the Company's trademarks had a gross
carrying amount of $23.1 million and accumulated amortization of $3.6 million,
which are no longer amortized because the Company has decided that this
intangible has an indefinite life.

Intangible assets of the Company, other than goodwill and trademarks, consist of
the following:

   accumulated amortization of $17,007
   and $16,673                                     1,146          1,480

                 Total                           $21,119        $21,961
- ------------------------------------------------------------------------


In connection with the adoption of SFAS No. 142, the Company reassessed the
useful lives and the classification of its identifiable assets and determined
that they continue to be appropriate. The weighted average useful lives of
patents was 13 years and covenants not to compete was 5 years.

Amortization expense for intangible assets was $1 million and $1.5 million for
the three months ended March 31, 2003 and 2002, respectively. Estimated
amortization expense for the remainder of 2003 and the five succeeding years are
as follows (in thousands):

     2003 (remainder)       $3,000
     2004                    2,876
     2005                    2,318
     2006                    2,177
     2007                    1,920
     2008                    1,473

There was no change in the carrying amount of goodwill for the three months
ended March 31, 2003. Goodwill for the freight group and transit group is $92.6
million and $16.9 million, respectively.

8. COMMITMENTS AND CONTINGENCIES

Under the terms of the purchase agreement and related documents for the 1990
Acquisition, American Standard, Inc. ("ASI"), has indemnified the Company for
certain items including, among others, environmental claims. The indemnification
provisions of the agreement expired at various dates through 2000, except for
those claims which were timely asserted, which continue until resolved. If ASI
was unable to honor or meet these indemnifications, the Company would be
responsible for such items. In the opinion of management, ASI currently has the
ability to meet its indemnification obligations.

The Company's and its affiliates' operations do not use and their products do
not contain any asbestos. Asbestos actions have been filed against the Company
and certain of its affiliates. Consistent with the experience of others, the
number of claims have increased in recent years. However, it is important to
note that these asbestos claims involve products sold prior to the 1990
formation of the Company. The Company and its affiliates have not incurred any
significant costs related to these asbestos claims. The claims are covered by
insurance or are subject to indemnity from the companies who manufactured or
sold the products in question. Management believes that these claims will not be
material; accordingly, the financial statements do not reflect any costs or
reserves for such claims.

The Company is subject to a number of other commitments and contingencies as
described in its Annual Report on Form 10-K for the Year Ended December 31,
2002. During the first quarter of 2003, there were no material changes to the
information described in Note 20 therein.

Also, as described in Note 20 of the Form 10-K, the Company is subject to a RCRA
Part B Closure Permit ("the Permit") issued by the Environmental Protection
Agency (EPA) and the Idaho Department of Health and Welfare, Division of
Environmental Quality relating to the monitoring and treatment of groundwater
contamination on, and adjacent to, the MotivePower Industries (Boise, Idaho)
facility. In compliance with the Permit, the Company has completed the first
phase of an accelerated plan for the treatment of contaminated groundwater, and
continues onsite and offsite monitoring for the amount of hazardous
constituents. At March 31, 2003, the Company has accrued $702,000 representing
the estimated remaining costs for remediation. The Company was in compliance
with the Permit at March 31, 2003.

On November 3, 2000, the Company settled a suit brought against it in 1999 by
GE-Harris Railway Electronics, L.L.C. and GE-Harris Railway Electronics
Services, L.L.C. (collectively "GE-Harris"). On September 20, 2002, a motion in
that lawsuit was filed by the successor to GE Harris, GE Transportation Services
Global Signaling, L.L.C. ("GETS-GS"). The motion by GETS-GS contends that the
Company is acting beyond authority granted in the parties' November 2000
settlement and license agreement and in contempt of the consent order that
concluded the suit at that time. In support of its motion, GETS-GS points
principally to sales and offers to sell certain railway brake equipment,
including distributed power equipment, to Australian customers. GETS-GS is
seeking substantial money damages and has claimed a significant business loss.
This matter is in discovery and a hearing on GETS-GS' motion is scheduled for
May 13, 2003.

9.  SEGMENT INFORMATION

Wabtec has two reportable segments - the Freight Group and the Transit Group.
The key factors used to identify these reportable segments are the organization
and alignment of the Company's internal operations, the nature of the products
and services, and customer type. The business segments are:

FREIGHT GROUP manufactures products and provides services geared to the
production and operation of freight cars and locomotives, including braking
control equipment, engines, on-board electronic components and train coupler
equipment. Revenues are derived from OEM sales and locomotive overhauls,
aftermarket sales and freight car repairs and services.

TRANSIT GROUP consists of products for passenger transit vehicles (typically
subways, commuter rail and buses) that



                                       9


include braking, coupling, and monitoring systems, climate control and door
equipment that are engineered to meet individual customer specifications.
Revenues are derived from OEM and aftermarket sales as well as from repairs and
services.

The Company evaluates its business segments' operating results based on income
from operations. Corporate activities include general corporate expenses,
elimination of intersegment transactions, interest income and expense and other
unallocated charges. Since certain administrative and other operating expenses
and other items have not been allocated to business segments, the results in the
following tables are not necessarily a measure computed in accordance with
generally accepted accounting principles and may not be comparable to other
companies.

Segment financial information for the three months ended March 31, 2003 is as
follows:

10.  RESTRUCTURING CHARGES
In 2001, the Company completed a merger and restructuring plan with charges
totaling $71 million pre-tax, with approximately $2 million of the charge
expensed in 2001, $20 million in 2000 and $49 million in 1999. The plan involved
the elimination of duplicate facilities and excess capacity, operational
realignment and related workforce reductions, and the evaluation of certain
assets as to their perceived ongoing benefit to the Company.

As of March 31, 2003, $402,000 of the merger and restructuring charge was still
remaining as accrued on the balance sheet as part of other accrued liabilities.
The table below identifies the significant components of the charge and reflects
the accrual balance at that date.

The lease impairment charges and asset writedowns are associated with the
Company's closing of several plants, the consolidation of the corporate
headquarters, and the Company's evaluation of certain assets where projected
cash flows from such assets over their remaining lives are estimated to be less
than their carrying values.

The Company began and completed a new restructuring plan for the Transit rail
business in 2001. The restructuring plan involved operational realignment and
related workforce reductions. The charges in 2001 for the restructuring plan
move totaled $2 million pre-tax. 2002 operations still included much of the cost
of integration in normal operations.

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

The following discussion should be read in conjunction with the information in
the unaudited condensed consolidated financial statements and notes thereto
included herein and Westinghouse Air Brake Technologies Corporation's Financial
Statements and Management's Discussion and Analysis of Financial Condition and
Results of Operations included in its 2002 Annual Report on Form 10-K.


OVERVIEW

Net sales of ongoing operations decreased by 4.4% from $177.3 million in the
first quarter of 2002 to $169.5 million in the same period in 2003. The major
cause for the change was the completion of a major transit contract during 2002,
which was partially offset by increased sales of components for new freight cars
and locomotives.

Net income from continuing operations for the first three months of 2003 was
$5.6 million or $0.13 per diluted share. Net loss from continuing operations for
the first three months of 2002 was $59 million or $1.36 per diluted share The
results for the first three months of 2002 included a $61.7 million, net of tax,
write off of goodwill in accordance with SFAS No. 142. Net income from
continuing operations before cumulative effect of accounting change was $2.6
million or $0.06 per diluted share. The increase in net income was due to
improved margins, lower operating expenses and lower interest expense.

                FIRST QUARTER 2003 COMPARED TO FIRST QUARTER 2002

The following table sets forth the Company's net sales by business segment:

- --------------------------------------------------------------------


Net sales for the first quarter of 2003 decreased $7.8 million, or 4.4%, to
$169.5 million as compared to the prior year period. The increased sales in the
Freight Group were offset by lower sales in the Transit Group. The Freight
Group's increased sales reflected higher sales of components for new freight
cars and locomotives and also higher aftermarket sales. In the quarter, industry
deliveries of new freight cars increased to 6,614 units as compared to 3,855 in
the same period in 2002. The Transit Group's decreased sales were due to the
completion of a contract to supply components for New York City subway cars and
lower aftermarket sales.

Gross profit increased to $45.3 million in the first quarter of 2003 compared to
$44.8 million in the same period of 2002. Gross profit is dependent on a number
of factors including pricing, sales volume and product mix. Gross profit, as a
percentage of sales, was 26.7% compared to 25.3% in the same period of 2002.
(Gross profit was 25.9% in the fourth quarter of 2002.) The increase in gross
profit percentage is primarily due to operating efficiencies and favorable
product mix.

Operating expenses improved by $1.3 million in the first quarter of 2003 as
compared to the same period of 2002, due to a decrease in selling, general and
administrative expenses and amortization expense.

Operating income totaled $12.3 million (or 7.3% of sales) in the first quarter
of 2003 compared with $10.5 million (or 5.9% of sales) in the same period in
2002. Higher operating income resulted from increased margins and decreased
operating expenses in the first quarter of 2003. (See Note 9 - "Notes to
Condensed Consolidated Financial Statements" regarding segment-specific
information, included elsewhere in this report).

Interest expense decreased 54.8% in the first quarter of 2003 as compared to the
prior year quarter primarily due to a substantial decrease in debt and interest
rates.

The effective income tax rate was 36.5% in the first quarter of 2003 and 35% in
the first quarter of 2002. The change in the effective tax rate was due to
increased state activity, resulting in a higher effective state tax rate.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity is provided primarily by operating cash flow and borrowings under the
Company's unsecured credit facility with a consortium of commercial banks
("credit agreement"). The following is a summary of selected cash flow
information and other relevant data.

Cash used by operations other than income taxes in the first three months of
2003 was $2.2 million compared to $4.8 million of cash provided by operations in
the same period a year ago. Earnings were the main provider of cash from
operations in the first three months of 2003 and 2002. An increase in accounts
receivable was the main use of cash from operations in the first three months of
2003. Planned income tax payments of approximately $30 million due to the fourth
quarter 2001 net



                                       11


gain from the sale of certain businesses to General Electric were the primary
use of cash from operations for the first three months of 2002.

Cash used for investing activities was $2.9 million in the first three months of
2003 as compared to $2.8 million a year ago. Capital expenditures for continuing
operations were $2.8 million and $3.1 in the first three months of 2003 and
2002, respectively. The majority of capital expenditures for these periods
relates to upgrades to existing equipment and replacement of existing equipment.
In the first three months of 2002, cash received from the sale of a product line
was $1.4 million and $1.7 million was paid to acquire the minority interest of a
business that the Company did not already own.

Cash used by financing activities was $3.1 million in the first three months of
2003 versus $698,000 of cash provided by financing activities in the same period
a year ago. The Company reduced long-term debt by approximately $2.9 million in
the first three months of 2003 compared to $411,000 in the same period a year
ago.

The following table sets forth the Company's outstanding indebtedness at March

Credit Agreement

The Company's credit agreement provides a $275 million five-year revolving
credit facility expiring in November 2004 and a 364-day $95 million convertible
revolving credit facility maturing in November 2004, with an annual renewal in
November 2003. At March 31, 2003, the Company had available borrowing capacity,
net of letters of credit, of approximately $161 million, subject to certain
financial covenant restrictions.

The Company believes, based on current levels of operations and forecasted
earnings, cash flow and liquidity will be sufficient to fund its working capital
and capital equipment needs as well as meeting the debt service requirements. If
the Company's sources of funds were to fail to satisfy the Company's cash
requirements, the Company may need to refinance its existing debt or obtain
additional financing. There is no assurance that such new financing alternatives
would be available, and, in any case, such new financing, if available, would be
expected to be more costly and burdensome than the debt agreements currently in
place. The Company currently expects to refinance and replace its existing bank
facility at least twelve months prior to its November 2004 expiration.

CRITICAL ACCOUNTING POLICIES

The preparation of the financial statements in accordance with generally
accepted accounting principles requires management to make judgments, estimates
and assumptions regarding uncertainties that affect the reported amounts of
assets and liabilities, disclosure of contingent assets and liabilities and the
reported amounts of revenues and expenses. Areas of uncertainty that require
judgments, estimates and assumptions include the accounting for derivatives,
environmental matters, the testing of goodwill and other intangibles for
impairment, proceeds on assets to be sold, pensions and other postretirement
benefits, and tax matters. Management uses historical experience and all
available information to make these judgments and estimates, and actual results
will inevitably differ from those estimates and assumptions that are used to
prepare the Company's financial statements at any given time. Despite these
inherent limitations, management believes that Management's Discussion and
Analysis of Financial Condition and Results of Operations (MD&A) and the
financial statements and related footnotes provide a meaningful and fair
perspective of the Company. A discussion of the judgments and uncertainties
associated with accounting for derivatives and environmental matters can be
found in the "Notes to Consolidated Financial Statements" included elsewhere in
this report.

A summary of the Company's significant accounting policies is included in Note 2
in the "Notes to Consolidated Financial Statements" included elsewhere in this
report. Management believes that the application of these policies on a
consistent basis enables the Company to provide the users of the financial
statements with useful and reliable information about the Company's operating
results and financial condition.

In 2002, Wabtec adopted the new standard of accounting for goodwill and
intangible assets with indefinite lives. The cumulative effect adjustment
recognized on January 1, 2002, upon adoption of the new standard, was a charge
of $61.7 million (after tax). Also in 2002, amortization ceased for goodwill and
intangible assets with indefinite lives. Additionally, goodwill and
indefinite-lived intangibles are required to be tested for impairment at least
annually. The evaluation of impairment involves comparing the current fair value
of the business to the recorded value (including goodwill). The Company uses a
combination of a guideline public company market approach and a discounted cash
flow model ("DCF model") to determine the current fair value of the business. A
number of significant assumptions and estimates are involved in the application
of the DCF model to forecasted operating cash flows, including markets and
market share, sales volume and pricing, costs to produce and working capital
changes. Management considers historical experience and all available
information at the time the fair values of its business are estimated. However,
actual fair values that could be realized in an actual transaction may differ
from those used to evaluate the impairment of goodwill.

Other areas of significant judgments and estimates include the liabilities and
expenses for pensions and other postretirement benefits. These amounts are
determined using actuarial methodologies and incorporate significant
assumptions, including the rate used to discount the future estimated liability,
the long-term rate of return on plan assets and several assumptions relating to
the employee workforce (salary increases, medical costs, retirement age and
mortality). The rate used to discount future estimated liabilities is determined
considering the rates available at year-end on debt instruments that could be
used to settle the obligations of the plan. The long-term rate of return is
estimated by considering historical returns and expected returns on current and
projected asset allocations and is generally applied to a five-year average
market value of assets.

The recent declines in equity markets and interest rates have had a negative
impact on Wabtec's pension plan liability and fair value of plan assets. As a
result, the accumulated benefit obligation exceeded the fair value of plan
assets at the end of 2002, which resulted in a $7.1 million, net of tax, charge
to other comprehensive loss in the fourth quarter.

As a global company, Wabtec records an estimated liability or benefit for income
and other taxes based on what it determines will likely be paid in various tax
jurisdictions in which it operates. Management uses its best judgment in the
determination of these amounts. However, the liabilities ultimately realized and
paid are dependent on various matters including the resolution of the tax audits
in the various affected tax jurisdictions and may differ from the amounts
recorded. An adjustment to the estimated liability would be recorded through
income in the period in which it becomes probable that the amount of the actual
liability differs from the recorded amount. Management does not believe that
such a charge would be material.



RECENT ACCOUNTING PRONOUNCEMENTS

See Notes 2 and 5 of "Notes to Condensed Consolidated Financial Statements"
included elsewhere in this report.



                                       13


QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE RISK

In the ordinary course of business, Wabtec is exposed to risks that increases in
interest rates may adversely affect funding costs associated with its
variable-rate debt. After considering the effects of interest rate swaps,
further described below, the Company's variable-rate debt represents 45% of
total long-term debt at March 31, 2003. Management has entered into pay-fixed,
receive-variable interest rate swap contracts that partially mitigate the impact
of variable-rate debt interest rate increases. An instantaneous 100 basis point
increase in interest rates would reduce the Company's annual earnings by
$552,000, assuming no additional intervention strategies by management.

See Note 2 of the Company's Notes to Condensed Consolidated Financial Statements
for the Quarterly Period Ended March 31, 2003 included herein for discussion of
swap contracts. These swap contracts are not expected to have a material effect
on the Company's financial condition, results of operations or liquidity.

FOREIGN CURRENCY EXCHANGE RISK

The Company occasionally enters into several types of financial instruments for
the purpose of managing its exposure to foreign currency exchange rate
fluctuations in countries in which the Company has significant operations. As of
March 31, 2003, the Company had no such instruments outstanding.

Wabtec is also subject to certain risks associated with changes in foreign
currency exchange rates to the extent its operations are conducted in currencies
other than the U.S. dollar. For the first three months of 2003, approximately
74% of Wabtec's net sales are in the United States, 10% in Canada, 1% in Mexico,
and 15% in other international locations, primarily Europe. At March 31, 2003,
the Company does not believe changes in foreign currency exchange rates
represent a material risk to results of operations, financial position, or
liquidity.

CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Wabtec's principal executive officer and its principal financial officer, based
on an evaluation as of a date within 90 days of the filing date of this report,
have concluded that Wabtec's disclosure controls and procedures (as defined in
Exchange Act Rules 13a-14(c) and 15d-14(c)) are adequate and effective to ensure
that material information relating to the Company and its consolidated
subsidiaries would be made known to them by others within those entities.

Changes in Internal Controls

There were no significant changes in Wabtec's internal controls or in other
factors that could significantly affect these controls and procedures subsequent
to the date of the evaluation.

LEGAL PROCEEDINGS AND COMMITMENTS AND CONTINGENCIES

There have been no material changes to report regarding the Company's
commitments and contingencies as described in Note 20 of the Company's Annual
Report on Form 10-K for the Year Ended December 31, 2002.
