                 MERGER PROPOSED -- YOUR VOTE IS VERY IMPORTANT

     The Boards of Directors of MotivePower Industries, Inc. and Westinghouse
Air Brake Company have approved a merger agreement which provides for the
combination of the two companies. We believe the combined company will be able
to create greater shareholder value than could be achieved by the companies
individually.

     Our combined company would be named MotivePower Industries, Inc., with its
headquarters in the Pittsburgh, Pennsylvania area.

     If the merger is completed, holders of WABCO common stock will receive, for
each WABCO share, 1.3 shares of MotivePower common stock. MotivePower
shareholders will continue to own their existing shares after the merger.

     MotivePower will issue approximately 44 million shares of MotivePower
common stock to WABCO shareholders in the merger, based on outstanding shares on
July 19, 1999. These shares will represent approximately      % of the
outstanding MotivePower common stock after the merger. MotivePower shares held
by MotivePower shareholders before the merger will represent approximately
     % of the outstanding MotivePower shares after the merger.

     We are asking shareholders of each of MotivePower and WABCO to approve and
adopt the merger agreement and the merger. We cannot complete the merger unless
shareholders of both companies approve it.

     The dates, times and places of the meetings are:

For MOTIVEPOWER shareholders:
Monday, August 23, 1999
11:00 a.m., Eastern Time
Two Gateway Center, Lobby Conference Center
Pittsburgh, Pennsylvania

For WABCO shareholders:

Monday, August 23, 1999
10:00 a.m., Eastern Time

DESCRIBE STARTING ON PAGE I-13 OF THIS JOINT PROXY STATEMENT/ PROSPECTUS.

secretary at the address under "The Companies" on page I-2.

Q: If my shares are held in "street name" by my broker, will my broker vote my
shares for me?

A: If you do not provide your broker with instructions on how to vote your
"street name" shares, your broker will not be permitted to vote them on the
merger. You should therefore be sure to provide your broker with instructions on
how to vote your shares.

If you are a MotivePower shareholder and do not give voting instructions to your
broker, you will not be counted as voting for purposes of the merger vote unless
you appear in person at the MotivePower meeting.

If you are a WABCO shareholder and do not give voting instructions to your
broker, you will, in effect, be voting against the merger unless you appear in
person at the WABCO meeting and vote in favor of the merger.

Q: Should I send in my stock certificates now?

A: No. If the merger is completed, we will send WABCO shareholders written
instructions for exchanging their share certificates. MotivePower shareholders
will keep their existing certificates.

Q: What will WABCO common shareholders receive for their shares?

A: WABCO shareholders will receive 1.3 shares of MotivePower common stock for
each of their shares of WABCO common stock. This exchange ratio will not change
even if the market price of MotivePower or WABCO common stock increases or
decreases between now and the date the merger is completed. Accordingly, WABCO
shareholders will not be able to determine the precise value of the shares of
MotivePower common stock they would receive in the merger at the time they vote
on the merger at their meeting. MotivePower will not issue any fractional shares
in the merger. Instead, WABCO shareholders will receive cash for any fractional
shares of MotivePower common stock owed to them in an amount based on the market
value of MotivePower common stock on the date on which the merger occurs.

Q: When do you expect the merger to be completed?

A: We are working towards completing the merger as quickly as possible. We hope
to complete the merger shortly after the meetings, assuming the required
shareholder approvals are obtained at the meetings.

Q: Who do I call if I have questions about the meetings or the merger?

A: MotivePower shareholders may call investor relations at (412) 201-1101.

WABCO shareholders may call investor relations at (412) 825-1000.

THE COMPANIES

MOTIVEPOWER INDUSTRIES, INC.
Two Gateway Center
14th Floor
Pittsburgh, Pennsylvania 15222
(412) 201-1101

MotivePower is a leader in the manufacturing and distribution of products for
rail and other power-related industries, and also provides a variety of related
contract services. MotivePower provides products and services to freight and
passenger railroads, including every Class I railroad in North America,
metropolitan transit and commuter rail authorities, original equipment
manufacturers, industrial power-related markets and other customers
internationally. MotivePower has its headquarters in Pittsburgh, Pennsylvania
and approximately 3,000 employees at strategically located facilities in the
United States, Canada and Mexico.

WESTINGHOUSE AIR BRAKE COMPANY
1001 Air Brake Avenue
Wilmerding, Pennsylvania 15148
(412) 825-1000

WABCO is one of North America's largest manufacturer of value-added equipment
for locomotives, railway freight cars and passenger transit vehicles. WABCO
believes that it maintains a market share in North America in excess of 50% for
its primary braking related equipment and a significant market share in North
America for its other principal products. WABCO also sells products in Europe,
Africa, Australia, South America and Asia. WABCO's major products are intended
to enhance safety, improve productivity and reduce maintenance costs for its
customers. WABCO's major product offerings include electronic controls and
monitors, air brakes, couplers, door controls, draft gears and brake shoes.
WABCO aggressively pursues technological advances with respect to both new
product development and product enhancements.

REASONS FOR THE MERGER

We believe the merger will:

- - create a premier supplier of products and services for the railroad industry,
  with combined revenues, based on 1998 results, exceeding $1 billion;

- - create significant revenue enhancement opportunities;

- - create a company with an improved cost structure that will allow for operating
  cost savings;

- - create opportunities for significant financial cost savings;

- - enable us to provide our customers with a "one-stop shop" for a more complete
  package of locomotive and freight car components and services;

- - create a combined company with increased financial strength to invest in new
  products and technologies;

- - combine two complementary companies with leading shares of their respective
  rail market segments and minimal product overlap; and

- - improve the combined company's position to make further acquisitions.

You should note, however, that achieving these objectives is subject to the
risks described on page I-13. These risks include, among others, possible
difficulties in integrating two companies that have previously operated
independently and in achieving anticipated synergies from the merger.

To review the reasons for the merger in greater detail, see pages I-29 through
I-35.

MERGER RECOMMENDATIONS TO SHAREHOLDERS

TO MOTIVEPOWER SHAREHOLDERS:

The MotivePower Board believes that the merger is fair to you and in your best
interest and recommends that you vote FOR the approval and adoption of the
merger agreement and the merger.

                                       I-2
   9

TO WABCO SHAREHOLDERS:

The WABCO Board believes that the merger is fair to you and in your best
interest and recommends that you vote FOR the approval and adoption of the
merger agreement and the merger.

THE MERGER

The merger agreement is attached as Annex A to this joint proxy
statement/prospectus. We encourage you to read the merger agreement as it is the
legal document that governs the merger.

WHAT WABCO SHAREHOLDERS WILL RECEIVE (SEE PAGE I-64)

As a result of the merger, WABCO shareholders will receive, for each share of
WABCO common stock, 1.3 shares of MotivePower common stock.

MotivePower will not issue any fractional shares. WABCO shareholders will
receive cash for any fractional shares of MotivePower common stock owed to them
in an amount based on the market value of MotivePower common stock on the date
on which the merger occurs.

Example:

- - If you currently own 75 shares of WABCO common stock, then after the merger
  you will receive 97 shares of MotivePower common stock and a check in an
  amount equal to .5 multiplied by the closing price of the MotivePower common
  stock on the date of the merger, rounded to the nearest one cent. The value of
  the stock that you will receive will fluctuate as the price of MotivePower
  common stock changes prior to and after the merger.

On July 19, 1999 the last per share price of MotivePower common stock reported
on the New York Stock Exchange was $18.06. Applying the 1.3 exchange ratio to
the MotivePower last reported price on that date, each holder of WABCO common
stock would be entitled to receive MotivePower common stock with a market value
of approximately $23.48 for each share of WABCO common stock. However, the
market prices for WABCO and MotivePower common stock are likely to change
between now and the merger. You are urged to obtain current price quotes for
WABCO and MotivePower common stock.

COMPARATIVE PER SHARE MARKET PRICE INFORMATION
MotivePower and WABCO common stock are both listed on the New York Stock
Exchange. On June 2, 1999, the last full trading day prior to the public
announcement of the proposed merger, MotivePower closed at $16.63 and WABCO
closed at $23.31. On July 19, 1999, MotivePower closed at $18.06 and WABCO
closed at $23.13.

LISTING OF MOTIVEPOWER COMMON STOCK

The shares of MotivePower common stock will be listed on the New York Stock
Exchange under the ticker symbol "MPO".

OWNERSHIP OF MOTIVEPOWER AFTER THE MERGER

MotivePower will issue approximately 44 million shares of MotivePower common
stock to WABCO shareholders in the merger. This includes 12 million shares to
WABCO's Employee Stock Ownership Plan, which we sometimes refer to in this joint
proxy statement/prospectus as "WABCO's ESOP". The shares of MotivePower common
stock to be issued to WABCO shareholders in the merger will represent
approximately      % of the outstanding MotivePower common stock after the
merger. This information is based on the number of MotivePower and WABCO shares
outstanding on July 19, 1999 and does not take into account stock options or
other equity-based awards.

SHARE OWNERSHIP OF OFFICERS AND DIRECTORS (SEE PAGE I-23)

On the record date, directors and executive officers of MotivePower and their
affiliates owned and were entitled to vote approximately 2,511,268 shares of
MotivePower common stock, or approximately 9.28% of the shares of MotivePower
common stock outstanding on the record date.

On the record date, directors and executive officers of WABCO and their
affiliates beneficially owned and were entitled to vote           shares of
WABCO common stock, or approximately 30.21% of the shares of WABCO common stock
outstanding on the record date.

SHAREHOLDER VOTE REQUIRED TO APPROVE AND ADOPT THE MERGER AGREEMENT AND THE
MERGER

For MotivePower shareholders: Approval and adoption of the merger agreement and
the merger

                                       I-3
   10

requires a majority of the votes cast at the meeting by holders of MotivePower
common stock.

For WABCO shareholders: Approval and adoption of the merger agreement and the
merger requires a majority of the votes represented by the outstanding shares of
WABCO common stock.

APPRAISAL RIGHTS (SEE PAGE I-37)

The holders of MotivePower and WABCO common stock do not have any "dissenters'
rights" or rights to an appraisal of the value of their shares in connection
with the merger.

BOARD OF DIRECTORS OF MOTIVEPOWER AND RELATED MATTERS AFTER THE MERGER (SEE PAGE
I-64)

Following the merger, the board of directors of MotivePower will have fourteen
members, including seven directors designated by MotivePower and seven directors
designated by WABCO.

INTEREST OF OFFICERS AND DIRECTORS IN THE MERGER (SEE PAGE I-57)

MotivePower and WABCO shareholders should note that a number of directors and
executive officers and certain shareholders of MotivePower and WABCO may have
interests in the merger that are different from, or in addition to, the
interests of shareholders generally.

ACCOUNTING TREATMENT (SEE PAGE I-35)

We expect the merger to qualify as a pooling of interests, which means that we
will treat our companies as if they had always been combined for accounting and
financial reporting purposes.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER (SEE PAGE
I-35)

It is a condition of the merger that MotivePower and WABCO each receive an
opinion to the effect that the merger constitutes a reorganization within the
meaning of Section 368(a) of the Internal Revenue Code, and that, among other
things, for federal income tax purposes, no gain or loss will be recognized by
MotivePower or WABCO as a result of the merger and no gain or loss will be
recognized by the shareholders of WABCO upon the conversion of their shares of
WABCO common stock into shares of MotivePower common stock pursuant to the
merger, except with respect to cash, if any, received in lieu of fractional
shares of MotivePower common stock.

The federal income tax consequences of the merger are discussed more fully on
pages I-35 through I-36. The consequences described herein do not address tax
consequences which may vary with, or are contingent upon, individual
circumstances. In particular, the federal income tax consequences described
herein may not apply to individuals who received WABCO common stock as
compensation or to shareholders who or which for United States federal income
tax purposes are nonresident alien individuals, foreign corporations, foreign
partnerships, foreign trusts or foreign estates. Also, special rules not
discussed herein might apply to WABCO's ESOP. We strongly urge each shareholder
of WABCO to consult the shareholder's tax advisor to determine the shareholder's
particular United States federal, state, local or foreign income or other tax
consequences resulting from the merger, in light of individual circumstances.

CONDITIONS TO THE COMPLETION OF THE MERGER (SEE PAGE I-68)

The completion of the merger depends upon meeting a number of conditions,
including the following:

- - approval and adoption of the merger agreement and the merger by the
  shareholders of MotivePower and WABCO;

- - absence of legal prohibition on completion of the merger;

- - receipt of letters from the independent public accountants of MotivePower and
  WABCO to the effect that the merger will qualify for "pooling of interests"
  accounting treatment;

- - receipt of opinions of MotivePower's and WABCO's legal counsel that, for
  federal income tax purposes, the merger will qualify as a reorganization; and

- - material accuracy as of closing of the representations and warranties made by
  each party.

REGULATORY APPROVALS (SEE PAGE I-36)

The merger is subject to regulatory approval. On June 22, 1999, MotivePower and
WABCO each filed notification and report forms under the Hart-Scott-Rodino
Antitrust Improvement Act with the FTC and the Antitrust Division of the U.S.

                                       I-4
   11

Department of Justice. On July 19, 1999, MotivePower and WABCO received notice
of early termination of the waiting period under the Hart-Scott-Rodino Antitrust
Improvements.

TERMINATION OF THE MERGER AGREEMENT (SEE PAGE I-69)

The Board of Directors of both our companies can jointly agree to terminate the
merger agreement at any time without completing the merger. Either company can
terminate the merger agreement if:

- - the merger is not completed by November 30, 1999;

- - the shareholders of either company fail to adopt and approve the merger
  agreement and the merger;

- - there is a permanent legal prohibition to closing the merger;

- - the other party materially breaches any of the representations or warranties
  it made or materially fails to comply with any of its obligations under the
  merger agreement;

- - the other party's Board does not recommend or modifies its recommendation of
  its merger proposal to its shareholders in a manner materially adverse to the
  company seeking to terminate the merger agreement;

- - the other party materially and knowingly breaches the covenant restricting its
  ability to negotiate with a third party concerning an alternative transaction;
  or

- - on or prior to July 17, 1999, either company's Board shall have determined to
  recommend an acquisition proposal made by a third party and to enter into a
  written agreement concerning the takeover proposal after determining that the
  proposal is more favorable than the merger.

TERMINATION FEES (SEE PAGE I-70)

WABCO must pay MotivePower up to $2 million of its out-of-pocket fees and
expenses incurred in connection with the merger plus a termination fee of $15
million in cash if the merger agreement is terminated because (1) the WABCO

WABCO stock option agreement under which WABCO granted to MotivePower an option
to purchase approximately 19% of WABCO's outstanding common stock, at a price of
$21.6125 per share which is adjustable in specified events. The option is
exercisable under the same circumstances in which WABCO is required

                                       I-5

                HISTORICAL AND PRO FORMA SELECTED FINANCIAL DATA

HOW WE PREPARED THE FINANCIAL STATEMENTS

     We are providing the following information to aid you in your analysis of
the financial aspects of the merger. We derived this information from the
MotivePower and WABCO audited financial statements for the years ended December
31, 1994 through 1998 and the unaudited financial statements for the three
months ended March 31, 1999 and 1998. The information is only a summary and you
should read it together with our historical financial statements and related
notes contained in the annual and quarterly reports and other information that
we have filed with the SEC. See "Where You Can Find More Information" on page
III-1.

POOLING OF INTERESTS ACCOUNTING TREATMENT

     We expect that the merger will be accounted for as a "pooling of
interests." This means that, for accounting and financial reporting purposes, we
will treat our companies as if they had always been combined. For a more
detailed description of pooling of interests accounting, see "The Merger
Transaction -- Accounting Treatment" on page I-35.

     We have presented unaudited pro forma condensed combined financial
information that reflects the pooling of interests method of accounting to give
you a better picture of what our businesses might have looked like had they been
combined since the beginning of the periods presented. We prepared the unaudited
pro forma condensed combined statements of income and unaudited pro forma
condensed combined balance sheet by adding or combining the historical amounts
of each company. The accounting policies of MotivePower and WABCO are
substantially comparable. However, adjustments were made to conform the
classification of amortization expense and income taxes receivable in the
unaudited pro forma condensed combined financial statements. The WABCO and
MotivePower combined company may have performed differently had they always been
combined. The unaudited pro forma condensed combined financial information may
not be indicative of the historical results that would have been achieved had
the companies always been combined or the future results that the combined
company will experience after the merger. See "Unaudited Pro Forma Condensed
Combined Financial Statements" on page I-39.

MERGER-RELATED EXPENSES

     We estimate that merger-related fees and expenses, consisting primarily of
SEC filing fees, fees and expenses of investment bankers, attorneys and
accountants, and financial printing and other related charges, will be
approximately $20-25 million. See note 5 on page I-47.

INTEGRATION-RELATED EXPENSES

     We estimate that costs of approximately $35-40 million will be incurred for
severance and other integration-related expenses, including the elimination of
duplicate facilities and excess capacity, operational realignment and related
workforce reductions. See note 5 on page I-47.

PERIODS COVERED

     The selected unaudited pro forma condensed combined financial data combines
MotivePower's and WABCO's results for the years ended December 31, 1996 through
1998 and the three months ended March 31, 1999 and 1998, and give effect to the
merger as if it had occurred at the beginning of the periods presented. The
combined balance sheet data in the table below combines the balance sheets of
MotivePower and WABCO as of December 31, 1996 through 1998 and as of March 31,
1999 and 1998.

COMPARATIVE PER SHARE DATA

     Set forth below are the net income, cash dividends and book value per
common share data separately for MotivePower and WABCO on a historic basis, for
MotivePower on a pro forma combined basis and on a pro forma combined basis per
WABCO equivalent share for each of the years ended December 31, 1998, 1997 and
1996 and for the three months ended March 31, 1999 and 1998. The exchange ratio
for the business combination is 1.3 shares of MotivePower common stock for each
share of WABCO common stock.

     The MotivePower pro forma data was derived by combining the historic
consolidated financial information of MotivePower and WABCO using the pooling of
interests method of accounting for business combinations as described under
"Unaudited Pro Forma Condensed Combined Financial Statements" beginning on page
I-39. The MotivePower historic per share information is restated to reflect a
three-for-two common stock split in the form of a 50 percent stock dividend
effective April 2, 1999.

     The WABCO equivalent share pro forma information shows the effect of the
merger from the perspective of an owner of WABCO common stock. The information
was computed by multiplying the MotivePower pro forma information by the
exchange ratio of 1.3.

     You should read the information below together with our historical
financial statements and related notes contained in the annual and quarterly
reports and other information that we have filed with the SEC. See "Where You

                                  RISK FACTORS

     In addition to the information included or incorporated by reference in
this joint proxy statement/
prospectus, you should consider the following matters in considering whether to
vote in favor of the merger proposal.

WABCO AND MOTIVEPOWER SHAREHOLDERS WILL NOT BE ABLE TO DETERMINE THE VALUE OF
MOTIVEPOWER STOCK AT THE TIME THAT THEY VOTE ON THE MERGER.

     Each share of WABCO common stock, other than shares owned directly or
indirectly by MotivePower or WABCO, will be converted at the effective time of
the merger into 1.3 shares of MotivePower common stock. Cash will be paid in
lieu of any fractional shares of MotivePower common stock that would otherwise
be issuable. The exchange ratio is a fixed number and will not be adjusted in
the event of any increases or decreases in the price of either MotivePower
common stock or WABCO common stock. Accordingly, WABCO shareholders will not be
able to determine the value of the MotivePower common stock they would receive
in the merger at the time they vote on the merger, and MotivePower shareholders
will not be able to determine the value of the MotivePower common stock to be
issued to the WABCO shareholders. In addition, neither party will have the right
to terminate the merger agreement or elect not to consummate the merger as a
result of changes in the market prices of either company's common stock. The
prices of MotivePower common stock and WABCO common stock at the effective time
may vary from their respective prices at the date of this joint proxy
statement/prospectus and at the date of the shareholder meetings, each to be
held on August 23, 1999. These variations may be the result of:

          - changes in the business, operations or prospects of MotivePower or
            WABCO,

          - market assessments of the likelihood that the merger will be
            consummated,

          - the timing of the merger and the prospects of the merger and
            post-merger operations,

          - regulatory considerations, and

          - general market and economic conditions and other factors.

     Because the effective time of the merger may occur at a date later than the
date on which the shareholder meetings occur, the prices of MotivePower common
stock and WABCO common stock on the date of the shareholder meetings may not be
indicative of their respective prices at the effective time of the merger.
MotivePower and WABCO shareholders are urged to obtain current market quotations
for MotivePower common stock and WABCO common stock. See "The Merger
Agreement -- Merger Consideration" on page I-64.

TERMINATION FEES AND RECIPROCAL STOCK OPTION AGREEMENTS COULD DETER ALTERNATIVE
TRANSACTIONS BY MAKING THEM MORE DIFFICULT OR EXPENSIVE.

     MotivePower or WABCO must pay to the other a termination fee of $15 million
plus up to $2 million in expenses if the merger agreement terminates under
specified circumstances. MotivePower and WABCO have also entered into reciprocal
stock option agreements which provide MotivePower and WABCO the right to acquire
up to 19% of the other's outstanding common stock under specified conditions,
with the profit either party can derive from the option limited to $15 million.
The termination fees and the stock option agreements could deter either
MotivePower or WABCO from entering into an alternative transaction by making an
alternative transaction more difficult or expensive. Among other effects, the
stock option agreements could prevent an alternative business combination with
WABCO or MotivePower from being accounted for as a "pooling of interests." The
stock option agreements may therefore discourage proposals for alternative
business combinations with WABCO or MotivePower, even if a third party were
prepared to offer shareholders of WABCO or MotivePower consideration with a
higher market value than the value of the MotivePower stock to be exchanged for
WABCO stock in the merger. For a further discussion of these matters, see
"Summary -- Termination Fees" on page I-5 and "Summary -- Stock Option
Agreements" on page I-5.

THE COMBINED COMPANY MAY NOT BE ABLE TO REALIZE THE COST SAVINGS AND OTHER
SYNERGIES OF THE MERGER OR SUCCESSFULLY INTEGRATE THE OPERATIONS OF MOTIVEPOWER
AND WABCO.

     The merger involves the integration of two companies that have previously
operated independently. WABCO and MotivePower expect to realize significant cost
savings and other synergies from the merger, but the combined company may not be
able to achieve these synergies or cost savings. Further, the costs of achieving
these synergies may be significantly greater than we anticipate. MotivePower and
WABCO estimate that the direct costs of the merger will be approximately $20-25
million. These costs are not included in the unaudited pro forma condensed
combined statements of income. See note 5 on page I-47. MotivePower and WABCO
also estimate that MotivePower will incur integration-related expenses,
including severance, of approximately $35-40 million. These costs are not
included in the unaudited pro forma condensed combined statements of income. See
note 5 on page I-47. These expenses may impact the combined company going
forward. In addition, if these costs and expenses are higher than estimated, the
merger benefits may be reduced. MotivePower and WABCO will also need to
integrate numerous systems, including management information, purchasing,
accounting and finance, sales, billing and payroll, which will require
substantial attention from management. MotivePower and WABCO do not expect that
they will complete their systems integration before the end of 1999. Diversion
of management attention to and difficulties associated with integrating
MotivePower and WABCO could harm the operating results of the combined company
and impact the value of its common stock.

THE COMBINED COMPANY'S ABILITY TO EXPAND ITS INTERNATIONAL OPERATIONS MAY BE
LIMITED BY THE NEED TO OBTAIN ADDITIONAL REGULATORY APPROVALS IN FOREIGN
JURISDICTIONS AND THE NEED TO MEET LOCAL EQUIPMENT REQUIREMENTS.

     MotivePower and WABCO conduct international operations through a variety of
wholly-owned subsidiaries, majority-owned subsidiaries and equity interests
located in the United States, Canada, Mexico, Europe, Australia and Asia.
MotivePower and WABCO are also exploring the possibility of expansion into other
international markets. The combined company's ability to expand sales of its
products internationally, in particular its locomotive and freight braking
products, is limited by the necessity of obtaining regulatory approval in new
jurisdictions. For example, local regulatory approval is required in order to
market WABCO's brake shoes in India. The combined company's international growth
strategy can also be hampered by the additional expense of modifying products to
comply with local railroad equipment requirements.

THE COMBINED COMPANY'S FINANCIAL PERFORMANCE ON A U.S. DOLLAR-DENOMINATED BASIS
MAY BE SIGNIFICANTLY AFFECTED BY FLUCTUATIONS IN CURRENCY EXCHANGE RATES.

     The combined company's international operations also pose risks due to
currency exchange rates. The combined company's financial performance is
reported on a U.S. dollar-denominated basis. However, MotivePower's and WABCO's
international operations are generally conducted in the currencies of the
countries in which such operations are located. Fluctuations in currency
exchange rates can negatively impact the combined company's financial results.

FLUCTUATIONS IN CUSTOMER ORDERS IN THE RAILWAY INDUSTRY DUE TO ECONOMIC
CONDITIONS AND ALTERNATE FORMS OF TRANSPORTATION CAN REDUCE THE COMBINED
COMPANY'S REVENUES AND HARM ITS FINANCIAL RESULTS.

     The railway industry has historically been subject to significant
fluctuations due to overall economic conditions and the level of use of
alternate methods of transportation. In economic downturns, railroads may defer
some expenditures in order to conserve cash in the short term and reductions in
freight traffic may reduce demand for the combined company's products. This
could reduce the combined company's revenues without a corresponding decrease in
its fixed costs. This can negatively impact the combined company's financial
results. We cannot assure you that the economic conditions will remain favorable
or that there will not be significant fluctuations adversely affecting the
industry as a whole and, as a result, the combined company.

CYCLICALITY IN THE PASSENGER TRANSIT INDUSTRY CAN REDUCE THE COMBINED COMPANY'S
REVENUES AND HARM ITS FINANCIAL RESULTS.

     Although many industries tend to be cyclical, the passenger transit railway
industry is particularly so. New passenger transit car orders vary from year to
year and are influenced greatly by major replacement programs and by the
construction or expansion of transit systems by transit authorities. Although
the combined company's revenues may be reduced at any time due to lack of orders
from the passenger transit industry, its fixed costs which are necessary to be
prepared for busy periods may stay the same. This can negatively impact the
combined company's financial results.

BECAUSE A MATERIAL PORTION OF THE COMBINED COMPANY'S FUTURE NET SALES WILL
DERIVE FROM GOVERNMENTAL OR OTHER PUBLIC ENTITIES, AND NOT PRIVATE COMPANIES, IT
CAN BE NEGATIVELY AFFECTED BY CHANGES IN POLITICAL, ECONOMIC OR SIMILAR
CONDITIONS.

     A substantial portion of WABCO's net sales have been, and WABCO and
MotivePower expect that a substantial portion of the combined company's future
net sales may be, derived from contracts with metropolitan transit and commuter
rail authorities and Amtrak. To the extent that future funding for proposed
public projects is curtailed or withdrawn altogether as a result of changes in
political, economic, fiscal or other conditions beyond the combined company's
control, these projects may be delayed or canceled, resulting in a potential
loss of new business.

INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS MAY REQUIRE THE COMBINED COMPANY TO
USE ITS CASH TO PAY FOR LEGAL FEES AND SETTLEMENTS OR JUDGMENTS.

     The combined company may be the subject of intellectual infringement claims
by third parties. Any infringement claims, even if meritless, will be costly and
time-consuming to defend. GE Harris Railway Electronics, LLC and GE Harris
Railway Electronic Services, LLC have brought suit against WABCO for alleged
patent infringement and unfair competition related to a communications system
installed in one of WABCO's products. These GE Harris entities are seeking to
prohibit WABCO from future infringement and are seeking an unspecified amount of
money damages to recover, in part, royalties. WABCO is defending, and the
combined company will continue to defend, these claims. However, if the combined
company is not successful, it may require the combined company to use its cash
to pay for legal fees and settlements or judgments.

YEAR 2000 ISSUES MAY NEGATIVELY AFFECT THE COMBINED COMPANY'S OPERATIONS AND THE
COMBINED COMPANY'S SUPPLIERS OR CUSTOMERS IN A MANNER WHICH COULD IMPACT THE
COMBINED COMPANY'S BUSINESS.

     The Year 2000 problem is the result of computer programs using two digits
rather than four to define the applicable year. Any of MotivePower's and WABCO's
computer programs that use two digits rather than four digits to specify the
year will be unable to interpret dates beyond December 31, 1999. This problem
could result in a system failure or miscalculations causing disruptions of
operations. The three major areas that could be critically affected are
financial and information system applications, manufacturing operations and
third-party relationships with vendors and with customers. MotivePower and WABCO
have developed plans to address this exposure. MotivePower and WABCO have
assessed financial and operational systems and manufacturing equipment,
developed and continue to develop detailed plans and have commenced conversion
efforts. Each of MotivePower and WABCO believes that its present remediation and
replacement programs will adequately address the Year 2000 problems with respect
to their internal systems in all material respects. However, the combined
company may experience minor disruptions with respect to the remediation and
replacement programs that are currently operating. In addition, MotivePower's
and WABCO's vendors, suppliers and other service providers may not successfully
resolve their own Year 2000 problems in a manner which avoids significant impact
to MotivePower and WABCO. MotivePower and WABCO have received written assurances
from some of their suppliers and customers and other providers acknowledging the
Year 2000 problems and stating their present intention to be compliant.
MotivePower and WABCO have not received assurances from all of their suppliers
and other providers and one or more key suppliers and other providers could fail
to become compliant in time to avoid a disruption to the combined company's
business.
                                      I-15
   22

A Year 2000 failure of the combined company's systems, or those of key suppliers
or other providers, could cause disruptions of its business. These disruptions
could include a slowdown or shutdown of production, an inability to invoice or
collect from customers, an inability to receive critical supplies or a reduction
in customer orders. Any one or more of these could harm the combined company's
financial results.

     MotivePower's and WABCO's products are generally sold with a limited
warranty for defects. MotivePower and WABCO have reviewed their products
currently in use by their customers or being sold and do not believe that there
will be material increases in warranty or liability claims arising out of Year
2000 non-compliance. However, a material increase in such claims could require
the combined company to apply substantial amounts of money or time to correct
any defects.

FOLLOWING THE MERGER THE COMBINED COMPANY WILL HAVE SUBSTANTIAL LEVERAGE AND
SERVICING DEBT WILL REQUIRE A SUBSTANTIAL PORTION OF THE COMBINED COMPANY'S CASH
FLOWS.

     Following the merger, MotivePower's leverage will increase as a result of
the assumption of WABCO's indebtedness. On a pro forma basis, after giving
effect to the merger, total indebtedness of the combined company as of December
31, 1998 would have been $573.6 million resulting in pro forma total
capitalization of the combined company of approximately 80% debt and 20% equity,
exclusive of the effect of any prepayment premiums, costs of refinancing or
costs of the merger, compared with actual company total indebtedness of $105.8
million and total capitalization of 37% debt and 63% equity as of December 31,
1998. The additional indebtedness will require the combined company to dedicate
a substantial portion of its future cash flow to the payment of principal and
interest on this indebtedness, thereby reducing funds available for capital
expenditures and future business opportunities. The combined company may choose
to refinance a significant portion of WABCO's and MotivePower's outstanding
long-term debt. In addition, management has plans to reduce indebtedness, but we
cannot be certain that we will be successful in either refinancing or reducing
the indebtedness of the combined company. The high level of debt may

     - limit the combined company's ability to fund future working capital,
       capital expenditures, research and development costs and other general
       corporate requirements,

     - increase the combined company's vulnerability to adverse economic and
       industry conditions,

     - limit the combined company's flexibility in planning for, or reacting to,
       changes in the combined company's business and the industry,

     - place the combined company at a competitive disadvantage compared to its
       competitors that have less debt, and

     - limit the combined company's ability to borrow additional funds.

WABCO'S CURRENT CREDIT FACILITIES LIMIT ITS ABILITY TO TAKE CERTAIN ACTIONS
WHICH MAY REQUIRE ACCELERATED REPAYMENT OF INDEBTEDNESS AFTER THE MERGER AND
WILL LIMIT THE COMBINED COMPANY'S ABILITY TO ENTER INTO SOME TRANSACTIONS AND TO
INCUR ADDITIONAL INDEBTEDNESS AFTER THE MERGER.

     Indebtedness under WABCO's current credit agreement is guaranteed by all of
WABCO's domestic subsidiaries and secured by substantially all of WABCO's and
its domestic subsidiaries' assets. WABCO's current credit agreement contains
covenants that, among other things, limit the payment of dividends and the
incurrence of additional debt and restricts mergers, acquisitions and sales of
assets or sales of the stock of WABCO's subsidiaries. WABCO is also required to
maintain specified financial ratios and meet other financial tests. Although
WABCO and MotivePower believe that the combined company will be able to maintain
compliance with the financial tests contained in WABCO's current credit
agreement, there can be no assurance that it will be able to do so. The
restrictions imposed by these covenants may adversely affect the combined
company's ability to make acquisitions or take advantage of favorable business
opportunities.

     WABCO believes that the proposed merger with MotivePower will constitute an
event of default under WABCO's credit agreement but not directly under either of
its indentures. WABCO anticipates receiving a waiver or renegotiating its credit
agreement prior to the merger. However, WABCO may not receive this

                                      I-16
   23

waiver or renegotiate the credit agreement on favorable terms. If WABCO does not
receive a waiver or successfully renegotiate the credit agreement prior to the
merger, a portion of WABCO's indebtedness would be payable.

     The indentures under which WABCO's 9 3/8% Notes due 2005 were issued also
contain covenants that, among other things, limit the ability of WABCO and some
of its subsidiaries to:

     - incur indebtedness,

     - pay dividends on and redeem capital stock,

     - create restrictions on investments in unrestricted subsidiaries,

     - make distributions from some subsidiaries,

     - use proceeds from the sale of assets and subsidiary stock,

     - enter into transactions with affiliates,

     - create liens and

     - enter into sale/leaseback transactions.

WABCO's requirement to meet the foregoing covenants impacts the manner in which
it operates its business and will limit the manner in which the combined company
operates after the merger. It could limit the combined company's ability to
spend money on capital projects, research and development costs, or similar
items. It could also make the combined company unable to complete acquisitions
or to take advantage of favorable business opportunities. Further, the combined
company's failure to meet any of the foregoing covenants could trigger defaults
under the WABCO credit facilities. The documents for the WABCO credit facilities
are cross-defaulted, so that defaults in one document would trigger defaults in
others and could cause the related indebtedness to become payable.

WABCO IS CURRENTLY INVOLVED IN ASBESTOS LITIGATION WHICH COULD, UNDER CERTAIN
CIRCUMSTANCES, REQUIRE THE COMBINED COMPANY TO USE SUBSTANTIAL AMOUNTS OF CASH
FOR LEGAL FEES AND SETTLEMENTS OR JUDGMENTS.

     WABCO and Railroad Friction Products Corporation and Vapor Corporation,
each wholly-owned subsidiaries of WABCO, are defendants in asbestos bodily
injury actions pending in various state and federal jurisdictions. WABCO
believes that pursuant to the asset purchase agreement by which it acquired the
North American operations of the railway products group of American Standard,
Inc., American Standard remains liable for all asbestos claims filed against
WABCO. Although WABCO believes that American Standard is willing and able to
fulfill its indemnity obligation, there can be no assurance that American
Standard will not dispute or become unable to perform its obligations. If this
occurs, the combined company would be required to use its cash to pay for legal
fees and settlements or judgments related to the asbestos claims.

     With respect to asbestos claims against Railroad Friction Products
Corporation, WABCO believes that the American Standard asset purchase agreement
requires American Standard to indemnify WABCO and Railroad Friction Products
Corporation for 50% of any liability and defense costs Railroad Friction
Products Corporation may incur with respect to asbestos claims. The remaining
costs are covered by insurance. American Standard's indemnity obligation with
respect to Railroad Friction Products Corporation claims expires in March 2000
in connection with claims that are initiated after that date. Again, although
WABCO believes that American Standard is willing and able to fulfill its
indemnity obligation with respect to Railroad Friction Products Corporation
asbestos claims, there can be no assurance that American Standard will not
dispute or become unable to perform its obligations. In addition, claims may be
made after American Standard's indemnification obligations expire and/or the
coverage afforded by insurance may at some time in the future be exhausted or
unavailable. If this occurs, the combined company would be required to use its
cash to pay for legal fees and settlements or judgments related to the asbestos
claims.

                                      I-17
   24

     Finally, WABCO believes that Mark IV Industries, Inc., the former owner of
Vapor is obligated to indemnify WABCO and Vapor for asbestos claims against
Vapor. Although WABCO believes that Mark IV is willing and able to fulfill its
indemnity obligation with respect to Vapor asbestos claims, there can be no
assurance that Mark IV will not dispute or become unable to perform its
obligations. If this occurs, the combined company would be required to use its
cash to pay for legal fees and settlements or judgments related to the asbestos
claims.

MOTIVEPOWER'S ANTI-TAKEOVER DEFENSE PROVISIONS MAY DETER POTENTIAL ACQUIRORS AND
MAY DEPRESS ITS STOCK PRICE.

     MotivePower's articles of incorporation and bylaws contain provisions that
could have the effect of making it more difficult for a third party to acquire,
or of discouraging a third party from attempting to acquire, control of
MotivePower. These provisions allow MotivePower to issue preferred stock with
rights senior to those of its common stock and impose various procedural and
other requirements that could make it more difficult for MotivePower
shareholders to effect some corporate actions.

     In addition, under MotivePower's shareholder rights plan, holders of
MotivePower common stock are entitled to one preferred share purchase right for
each outstanding share of common stock they hold, exercisable under specified
circumstances involving a potential change of control, as discussed in
"Description of MotivePower Capital Stock -- Shareholder Rights Plan" on page
II-15. The preferred share purchase rights have the anti-takeover effect of
causing substantial dilution to a person or group that attempts to acquire
MotivePower on terms not approved by the MotivePower Board. The foregoing
provisions could reduce the premium that potential acquirors might be willing to
pay in an acquisition or that investors might be willing to pay in the future
for shares of MotivePower common stock.

* Under NYSE rules, if your broker holds your shares in its name, your broker is
  not permitted to vote your shares on the merger proposals if it does not
  receive voting instructions from you. Without your voting instructions, a
  broker non-vote will occur on the merger proposals, which will (1) have no
  effect on the vote to approve and adopt the merger agreement and the merger in
  the case of MotivePower and (2) have the effect of a vote against approval and
  adoption of the merger agreement and the merger in the case of WABCO. The
  differences in the effect of abstentions and broker "non-votes" for
  MotivePower and WABCO are due to differences in state corporate law in
  Pennsylvania, where MotivePower is incorporated, and Delaware, where WABCO is
  incorporated.

     Revoking Your Proxy. You may revoke your proxy before it is voted by:

          - submitting a new proxy with a later date,

          - notifying your company's corporate secretary in writing before the
            meeting that you have revoked your proxy, or

          - voting in person at the meeting.

     Voting in person. If you plan to attend a meeting and wish to vote in
person, we will give you a ballot at the meeting. However, if your shares are
held in the name of your broker, bank or other nominee, you must bring an
account statement or letter from the nominee indicating that you are the
beneficial owner of the shares on July 19, 1999, the record date for voting.

     Proxy solicitation. We will pay our own costs of soliciting proxies.

     In addition to this mailing, MotivePower and WABCO employees may solicit
proxies personally, electronically or by telephone.

     The extent to which these proxy soliciting efforts will be necessary
depends entirely upon how promptly proxies are submitted. You should send in
your proxy by mail without delay. We reimburse brokers and other nominees for
their expenses in sending these materials to you and getting your voting
instructions.

     Do not send in any stock certificates with your proxy cards. The exchange
agent will mail transmittal forms with instructions for the surrender of stock
certificates for WABCO common stock to former WABCO shareholders as soon as
practicable after the completion of the merger.

OTHER BUSINESS; ADJOURNMENTS

     We are not currently aware of any other business to be acted upon at either
meeting.

     Adjournments may be made for the purpose of, among other things, soliciting
additional proxies. Any adjournment may be made from time to time by approval of
the holders of shares representing a majority of the votes present in person or
by proxy at the meeting, whether or not a quorum exists, without further notice
other than by an announcement made at the meeting. Neither of us currently
intends to seek an adjournment of our meeting.

                             THE MERGER TRANSACTION

GENERAL

     MotivePower's Board is using this joint proxy statement/prospectus to
solicit proxies from the holders of MotivePower common stock for use at the
MotivePower meeting. WABCO's Board is also using this document to solicit
proxies from the holders of WABCO common stock for use at the WABCO meeting.

  MotivePower Proposal

     At the MotivePower meeting, holders of MotivePower common stock will be
asked to vote upon approval and adoption of the merger agreement and the merger.

  WABCO Proposal

     At the WABCO meeting, holders of WABCO common stock will be asked to vote
upon approval and adoption of the merger agreement and the merger.

BACKGROUND OF THE MERGER

     The management of each of MotivePower and WABCO continually review their
company's respective positions as leaders in the rail products and service
industry with the objective of determining what alternatives are available to
further enhance shareholder value in the competitive environment of the
industry. While both companies believe they have positive future prospects on a
stand-alone basis, in recent years, the managements of both MotivePower and
WABCO have had conversations with a number of other companies regarding a range
of options to improve their competitive positions, including acquisitions or
dispositions of assets, possible partnerships, alliances or other significant
transactions.

     In March 1998, WABCO and MotivePower formed a joint venture in Mexico to
build locomotive and railcar components. In September 1998, WABCO and
MotivePower expanded their joint venture to include the repair and maintenance
of some of the electronics equipment manufactured by WABCO. On October 26 and
27, 1998, John C. Pope, Chairman of the Board of MotivePower, Michael A. Wolf,
President and Chief Executive Officer of MotivePower, Joseph S. Crawford,
Executive Vice President and Chief Operating Officer of MotivePower, William E.
Kassling, Chairman and Chief Executive Officer of WABCO, and Gregory T.H.
Davies, President and Chief Operating Officer of WABCO, attended a ribbon
cutting ceremony for the Mexican joint venture. At the ribbon cutting ceremony,
the parties discussed the positive aspects of their joint venture and agreed to
explore the possibility of expanding and enhancing the joint venture product
offerings and pursuing joint opportunities.

     On March 15 and 16, 1999, Messrs. Kassling and Davies participated in tours
of MotivePower's plants in Chicago and Boise with Messrs. Pope, Wolf and
Crawford. The primary purpose of these tours was to allow Messrs. Kassling and
Davies to obtain a better understanding of MotivePower's business, including
obtaining an understanding of existing commercial arrangements with customers
and suppliers and the products and services offered by MotivePower in order to
consider the addition of new product lines to the joint venture.

     On March 19, 1999, Messrs. Pope and Kassling met to discuss the cultural
and philosophical differences and similarities of each of the companies.

     On April 8 and 9, 1999, Messrs. Pope, Wolf and Crawford participated in
tours of WABCO's plants in Spartanburg, Germantown, Hamilton and Chicago with
Messrs. Kassling and Davies. The primary purpose of these tours was to allow
Messrs. Pope, Wolf and Crawford to obtain a better understanding of WABCO's
business, including obtaining an understanding of existing commercial
arrangements with customers and suppliers and the products and services offered
by WABCO in order to consider the addition of new product lines to the joint
venture.

     At a special meeting of the MotivePower Board on April 12, 1999, Mr. Pope

further enhancing shareholder value over what could be achieved on a stand-alone
basis, as well as on the status of the discussions with WABCO. MotivePower

     At a meeting of the MotivePower special committee held on May 25, 1999,
MotivePower management and MotivePower's financial and legal advisors and its
independent accountants updated the special committee on further due diligence
performed with respect to WABCO and the status of the discussions pertaining to
the proposed merger.

     On May 26, 1999, MotivePower's financial and legal advisors had a telephone

conference the parties discussed due diligence issues and some of the open
issues in the merger agreement.

     On May 27, 1999, the MotivePower Board held a special meeting at which it
was updated on due diligence performed with respect to WABCO, the status of
discussions between MotivePower and WABCO and various financial, accounting and
legal considerations of the proposed transaction.

     On May 27, 1999, the WABCO Board held a special meeting to discuss the
status of due diligence, deal structure and the progress of the negotiations. At
this meeting, WABCO's legal counsel made a presentation about the terms and
conditions of the merger agreement and the stock option agreements.

     On the evening of May 27, Messrs. Kassling, Pope and James P. Kelley, a
director of WABCO, met and discussed some unresolved terms of the merger,
including board composition and the exchange ratio.

     On June 1, 1999, Messrs. Kassling and Pope had telephone conversations
where they discussed board representation and the composition and function of
some of the committees of the MotivePower Board. Messrs. Kassling and Pope also
discussed Mr. Pope's duties, responsibilities and powers as Chairman of
MotivePower and Mr. Kassling's future duties, responsibilities and powers as
Chief Executive Officer of MotivePower.

     On June 1, 1999, the WABCO Board held a special meeting to discuss the
status of due diligence, corporate governance issues, acceptable exchange ratios
and the proposed transaction generally.

     At a special meeting held on the morning of June 2, 1999, the MotivePower
Board was updated on due diligence performed with respect to WABCO and reviewed
with its legal and financial advisors the principal terms of the merger
agreement and stock option agreements and various financial, legal, accounting
and other issues relating to the merger. The MotivePower Board discussed
possible exchange ratios.

     At a special meeting of the WABCO Board on June 2, 1999, WABCO's legal
counsel reviewed legal matters pertaining to the proposal transaction. The WABCO
Board also discussed and identified the parameters of the exchange ratio within
which it would be prepared to authorize WABCO to enter into the merger agreement
and stock option agreements. CSFB orally delivered its fairness opinion to the
WABCO Board. After due consideration, the WABCO Board unanimously approved the
merger agreement, the stock option agreements and the related merger matters
described in this document and determined to recommend that the WABCO
shareholders adopt and approve the merger agreement and the merger, all subject
to negotiation of an exchange ratio within the parameters specified by the WABCO
Board. The WABCO Board authorized WABCO's financial advisor and some of the
members of management to negotiate an exchange ratio within the approved
parameters.

                                      I-28
   35

     Promptly after the conclusion of the special meeting of the WABCO Board,
WABCO's financial advisor telephoned MotivePower's financial advisor to further
negotiate the exchange ratio. The result of these negotiations was that WABCO's
financial advisor and Mr. Kassling advised MotivePower's financial advisors and
Mr. Pope, respectively, that WABCO would not be willing to enter into the
proposed transactions at an exchange ratio of less than 1.3, which ratio was
within the parameters approved by the WABCO Board and was consistent with CSFB's
fairness opinion.

     At a special meeting of the MotivePower Board held late in the afternoon on
June 2, 1999 to consider the merger, the MotivePower Board discussed the
exchange ratio that had been proposed by the WABCO Board. The MotivePower Board
then reviewed the terms of the proposed merger agreement and stock option
agreements. MotivePower's legal advisors reviewed various legal considerations
relating to the proposed merger. The MotivePower Board then received a financial
presentation from and the oral fairness opinion of Wasserstein Perella.
Following these presentations, and a discussion regarding the strategic benefits
of the proposed merger and of the terms and conditions of the merger agreement
and the stock option agreements, the MotivePower Board unanimously approved the
merger agreement and the stock option agreements and determined to recommend
that the MotivePower shareholders adopt and approve the merger agreement and
merger.

     Following the approval of their Boards, MotivePower and WABCO executed the
merger agreement and the stock option agreements, and issued a joint press
release promptly thereafter prior to the opening of NYSE trading.

     On July 19, 1999, MotivePower and WABCO amended the merger agreement in
certain minor respects.

FACTORS CONSIDERED BY, AND RECOMMENDATION OF, THE MOTIVEPOWER BOARD

     At a meeting of the MotivePower Board held on June 2, 1999, after due
consideration, the MotivePower Board unanimously:

          (1) determined that the merger agreement, the merger, the MotivePower
     stock option agreement, the WABCO stock option agreement and the related
     transactions are advisable, consistent with, in furtherance of and
     otherwise in the best interests of MotivePower and its shareholders,

          (2) approved the merger agreement, the merger, the stock option
     agreements and the related transactions, and

          (3) determined to recommend that the shareholders of MotivePower
     approve and adopt the merger agreement and the merger.

     Accordingly, the MotivePower Board recommends that the MotivePower
shareholders vote "FOR" the approval and adoption of the merger agreement and
the merger.

                                      I-29
   36

     In approving the transaction and making these recommendations, the
MotivePower Board consulted with MotivePower's management as well as its outside
legal counsel and financial advisor, and considered, among other things, the
following material factors:

          (1) the business, operations, financial condition, earnings and
     prospects of each of MotivePower and WABCO; in making its determination,
     the MotivePower Board took into account its familiarity with, and the
     results of MotivePower's due diligence review of, WABCO's business,
     operations, financial condition, earnings and prospects;

          (2) the scale, scope and strength of the operations of the combined
     company, which will create a premier supplier of products and services for
     the railroad industry;

          (3) the competitive advantage that the combined company could achieve
     through the combination of WABCO's technological strengths as a designer
     and producer of electronic controls, monitors and air brakes with
     MotivePower's strengths as a producer and servicer of locomotives along
     with the minimal product overlap between the two companies;

          (4) the further competitive advantage that the combined company would
     have as a result of incorporating WABCO's considerable process technology
     and know-how in production of products made by MotivePower;

          (5) the benefits that the combined company could achieve by
     cross-selling products and services to the customers of the other with
     minimal existing product overlap;

          (6) the anticipated financial impact of the proposed transaction on
     the combined company's future financial performance;

          (7) the expectation that the merger would create opportunities for
     significant operational and financial cost savings, including significant
     operating advantages relative to competitors and to MotivePower on a
     stand-alone basis;

          (8) the possibility, as alternatives to the merger, of pursuing an
     acquisition of or a business combination or joint venture with an entity
     other than WABCO and the MotivePower Board's conclusion that a transaction
     with WABCO is more feasible, and is expected to yield greater benefits,
     than the likely alternatives; the MotivePower Board reached this conclusion
     for reasons such as WABCO's interest in pursuing a transaction with
     MotivePower, and MotivePower management's assessment of the alternatives
     and the expected benefits of the merger and compatibility of the companies
     as described above;

          (9) the fact that WABCO shareholders would hold approximately 55% of
     the outstanding stock of the combined company after the merger, on a fully
     diluted basis, excluding shares held by the WABCO ESOP;

          (10) the intended accounting of the merger as a pooling of interests
     which results in combined financial statements prepared on a basis
     consistent with the underlying view that shareholder interests in the two
     companies have simply been combined, and in the preservation of the
     historical cost approach for both MotivePower and WABCO;

          (11) the ability to complete the merger as a tax-free reorganization
     for U.S. federal income tax purposes;

          (12) the terms and conditions of the merger agreement, including the
     fact that shares of MotivePower common stock are being issued in the
     merger, that, subject to specified limitations, each company may provide
     information to interested third-party bidders if its board determines in
     good faith after consultation with legal counsel that it is necessary to do
     so to avoid a breach of its fiduciary duties to the company or its
     shareholders, that although the merger agreement may be terminated after
     November 30, 1999 due to the failure of the conditions to the merger to be
     met, the merger agreement provides for its earlier termination on or prior
     to July 17, 1999 to enable either party to enter into an alternative
     transaction, and each party's agreement to pay the other a $15 million
     break-up fee and specified out-of-pocket expenses under specified
     circumstances and to enter into the stock option
                                      I-30
   37

     agreements (see "The Merger Agreement -- Conditions to the Completion of
     the Merger" on page I-68, "The Merger Agreement -- Termination of the
     Merger Agreement" on page I-69 and "The Merger Agreement -- Stock Option
     Agreements" on page I-71);

          (13) the grant to MotivePower of an option to acquire WABCO common
     stock exercisable under specified circumstances pursuant to the WABCO stock
     option agreement (see "The Merger Agreement -- Stock Option Agreements" on
     page I-71);

          (14) the grant to WABCO of an option to acquire MotivePower common
     stock exercisable under specified circumstances pursuant to the MotivePower
     stock option agreement (see "The Merger Agreement -- Stock Option
     Agreements");

          (15) that while the termination payment provisions of the merger
     agreement could have the effect of discouraging alternative proposals for a
     business combination with MotivePower and that the MotivePower stock option
     agreement could prevent an alternative business combination with
     MotivePower from being accounted for as a pooling of interests, these
     provisions would not preclude bona fide alternative proposals, and that the
     size of the termination fee was reasonable in light of the size and
     benefits of the transaction;

          (16) the role that MotivePower's current management is expected to
     have in the management of the combined company, in particular MotivePower
     management's participation in the transition and the intention of
     MotivePower and WABCO to capitalize on the best management resources of
     both companies in the combined company;

          (17) the corporate governance structure reflected in the merger
     agreement, including that immediately after the merger the MotivePower
     Board would be comprised of an equal number of directors from MotivePower
     and WABCO and that seven of the WABCO Board's members would become
     directors of MotivePower, as described under "The Merger
     Agreement -- MotivePower Board and Related Matters" on page I-64, and that
     deadlocks on the MotivePower Board would be referred to an Executive
     Committee of MotivePower, a majority of members of which would be former
     WABCO directors and the Chairman of which would initially be the former
     Chief Executive Officer of WABCO;

          (18) the interests that executive officers and directors of
     MotivePower may have with respect to the merger in addition to their
     interests as shareholders of MotivePower generally (see "Interests of
     Certain Persons in the Merger" on page I-57);

          (19) the analyses and presentations of Wasserstein Perella, and
     Wasserstein Perella's written opinion to the effect that, as of June 2,
     1999, and based upon and subject to the various considerations set forth in
     its opinion, the exchange ratio was fair from a financial point of view to
     MotivePower;

          (20) the challenges of combining the businesses and cultures of two
     corporations of this size and the attendant risk of not achieving the
     expected cost savings and revenue synergies, as discussed under "Risk
     Factors" on page I-13 and "Cautionary Statement Concerning Forward-Looking
     Statements" on page I-19, and of diverting management focus and resources
     from other strategic opportunities and operational matters for an extended
     period of time;

          (21) the amount of WABCO's outstanding indebtedness and the fact that
     the combined company would be more highly leveraged than MotivePower on a
     stand-alone basis;

          (22) the fact that the number of shares of MotivePower common stock to
     be issued to the shareholders of WABCO in the merger is a fixed number of
     shares per share of WABCO common stock that will not fluctuate due to
     changes in the share price of MotivePower;

          (23) the increased market capitalization and public stockholding that
     the combined company would have in contrast to that of either company
     individually which should provide greater liquidity to each company's
     shareholders;

          (24) the lack of availability of dissenters' rights; and

                                      I-31
   38

          (25) the likelihood of consummation of the merger.

     In view of the wide variety of factors considered in connection with its
evaluation of the merger and the complexity of these matters, the MotivePower
Board did not find it useful to and did not attempt to quantify, rank or
otherwise assign relative weights to these factors. The MotivePower Board relied
on the experience and expertise of Wasserstein Perella, its financial advisor,
for quantitative analysis of the financial terms of the merger. See "Opinions of
Financial Advisors -- Opinion of MotivePower Financial Advisor" on page I-47. In
addition, the MotivePower Board did not undertake to make any specific
determination as to whether any particular factor, or any aspect of any
particular factor, was favorable or unfavorable to the MotivePower Board's
ultimate determination, but rather the MotivePower Board conducted an overall
analysis of the factors described above, including through discussions with and
questioning of MotivePower's management and legal, financial and accounting
advisors. In considering the factors described above, individual members of the
MotivePower Board may have given different weight to different factors.

     The MotivePower Board considered all these factors as a whole, and overall
considered the factors to be favorable to and to support its determination.
However, the general view of the MotivePower Board was that items 9, 14, 17, 20,
21 and 24 above were unfavorable factors relating to the transaction, and that
the other reasons and factors described above were generally considered
favorable.

FACTORS CONSIDERED BY, AND RECOMMENDATION OF, THE WABCO BOARD

     At a meeting of the WABCO Board held on June 2, 1999, after due
consideration, the WABCO Board unanimously:

                                      I-32
   39

          (5) the benefits that the combined company could achieve by marketing
     the combined company's products and services to the customers of the other
     with minimal existing product overlap;

          (6) the anticipated financial impact of the proposed transaction on

          (11) the ability to complete the merger as a tax-free reorganization
     for U.S. federal income tax purposes;

          (12) the terms and conditions of the merger agreement, including the
     fact that MotivePower would be the surviving corporation in the merger,
     that, subject to specified limitations, each company may provide
     information to interested third-party bidders if its board determines in
     good faith after consultation with legal counsel that it is necessary to do
     so to avoid a breach of its fiduciary duties to the company or its

     I-68, "The Merger Agreement -- Termination of the Merger Agreement" on page
     I-69 and "The Merger Agreement -- Stock Option Agreements" on page I-71);

          (13) the grant to MotivePower of an option to acquire WABCO common
     stock exercisable under specified circumstances pursuant to the WABCO stock
     option agreement (see "The Merger Agreement -- Stock Option Agreements" on
     page I-71);

   40

          (16) the role that WABCO's and MotivePower's current management is
     expected to have in the management of the combined company, in particular
     WABCO management's participation in the senior management of the surviving
     corporation, the continuation of Mr. Pope as Chairman of MotivePower, and
     the intention of WABCO and MotivePower to capitalize on the best management
     resources of both companies in the combined company;

          (17) the corporate governance structure reflected in the merger
     agreement, including that immediately after the merger the MotivePower
     Board would be comprised of an equal number of directors from MotivePower
     and WABCO and that seven of the WABCO Board's members would become
     directors of MotivePower, as described under "The Merger
     Agreement -- MotivePower Board and Related Matters" on page I-64, that
     specified deadlocks on the MotivePower Board would be referred to an
     Executive Committee of MotivePower, a majority of members of which would be
     former WABCO directors and the Chairman of which would initially be Mr.
     Kassling, Chief Executive Officer of WABCO, and the other provisions of
     MotivePower's corporate governance documents that will become effective
     upon consummation of the Merger;

          (18) the interests that some executive officers and directors of WABCO
     may have with respect to the merger in addition to their interests as
     shareholders of WABCO generally (see "Interests of Certain Persons in the
     Merger" on page I-57);

          (19) the analyses and presentations of Credit Suisse First Boston, and
     Credit Suisse First Boston's written opinion to the effect that, as of June
     2, 1999, and based upon and subject to the various considerations set forth
     in its opinion, the exchange ratio was fair from a financial point of view
     to WABCO;

          (20) the challenges of combining the businesses and cultures of two
     corporations of this size and the attendant risk of not achieving the
     expected cost savings and revenue synergies, as discussed under "Risk
     Factors" on page I-13 and "Cautionary Statement Concerning Forward-Looking
     Statements" on page I-19 and of diverting management focus and resources
     from other strategic opportunities and operational matters for an extended
     period of time;

          (21) the amount of WABCO's outstanding indebtedness and the fact that
     the combined company would be less highly leveraged than WABCO on a
     stand-alone basis;

          (22) the fact that the number of shares of MotivePower common stock to
     be issued to the shareholders of WABCO in the merger is a fixed number of
     shares per share of WABCO common stock that will not fluctuate due to
     changes in the share price of MotivePower;

          (23) the increased market capitalization and public stockholding that
     the combined company would have in contrast to that of either company
     individually which should provide greater liquidity to each company's
     shareholders;

          (24) the necessity to terminate prior to the merger the existing
     voting trust arrangements and stockholders agreement among various of the
     WABCO stockholders in order to facilitate the intended accounting as a
     pooling of interests;

          (25) the lack of availability of dissenters' rights; and

          (26) the likelihood of consummation of the merger.

     In view of the wide variety of factors considered in connection with its
evaluation of the merger and the complexity of these matters, the WABCO Board
did not find it useful to and did not attempt to quantify, rank or otherwise
assign relative weights to these factors. The WABCO Board relied on the
experience and expertise of Credit Suisse First Boston, its financial advisor,
for quantitative analysis of the financial terms of the merger. See "Opinions of
Financial Advisors -- Opinion of WABCO Financial Advisor" on page I-52. In
addition, the WABCO Board did not undertake to make any specific determination
as to whether any particular factor, or any aspect of any particular factor, was
favorable or unfavorable to the WABCO Board's ultimate determination, but rather
the WABCO Board conducted an overall analysis of the factors described

                                      I-34
   41

above, including thorough discussions with and questioning of WABCO's management
and legal, financial and accounting advisors. In considering the factors
described above, individual members of the WABCO Board may have given different
weight to different factors.

     The WABCO Board considered all these factors as a whole, and overall
considered the factors to be favorable to and to support its determination.
However, the general view of the WABCO Board was that items 13, 20, 24 and 25
above were unfavorable factors relating to the transaction, and that the other
reasons and factors described above were generally considered favorable.

ACCOUNTING TREATMENT

     MotivePower and WABCO intend for the merger to be accounted for under the
"pooling of interests" method under the requirements of Opinion No. 16 (Business
Combinations) of the Accounting Principles Board of the American Institute of
Certified Public Accountants, the Financial Accounting Standards Board, and the
rules and regulations of the SEC.

     Management of MotivePower and WABCO expect that the merger will be treated
as a pooling of interests transaction for accounting purposes.

     The receipt of letters from Deloitte & Touche LLP and Arthur Andersen LLP
dated as of the closing date of the merger to the effect that the merger will
qualify for pooling of interests accounting treatment is a condition to the
closing of the merger.

     Under the pooling of interests accounting method, the reported balance
sheet amounts and results of operations of the separate companies for prior
periods will be combined, reclassified and conformed, as appropriate, to reflect
the combined financial position and results of operations for MotivePower. See
"Unaudited Pro Forma Condensed Combined Financial Statements."

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     The following discussion summarizes the material United States federal
income tax consequences of the merger. The discussion that follows is based on
and subject to the Internal Revenue Code, Treasury Regulations under the
Internal Revenue Code, existing administrative interpretations and court
decisions in effect as of the date of this proxy statement/prospectus, all of
which are subject to change, possibly with retroactive effect, and all of which
are subject to differing interpretation. The following discussion does not
address the effects of the merger under any state, local or foreign tax laws.

     The tax treatment of a WABCO shareholder may vary depending upon the
shareholder's particular situation, and certain WABCO shareholders, including
insurance companies, tax-exempt organizations, financial institutions, broker
dealers, persons who do not hold WABCO common stock as capital assets, employees
of WABCO, and individuals who hold WABCO common stock as part of a straddle or
conversion transaction, may be subject to special rules not discussed below. For
example, special rules not discussed below might apply to WABCO's ESOP. Each
WABCO shareholder is urged to consult his or her tax advisor with respect to the
specific tax consequences of the merger, including the effect of United States
federal, state and local, and foreign and other tax rules, and the effect of
possible changes in tax laws.

     It is a condition to the obligation of MotivePower to effect the merger
that MotivePower receive an opinion from its counsel, Sidley & Austin, and it is
a condition to the obligation of WABCO to effect the merger that WABCO receive
an opinion from its counsel, Kirkland & Ellis, in each case to the effect that
the merger constitutes a reorganization within the meaning of Section 368(a) of
the Internal Revenue Code for federal income tax purposes, and in each case to
the following effect:

        Tax Consequences to MotivePower and WABCO. For federal income tax
      purposes, no gain or loss will be recognized by MotivePower or WABCO as a
      result of the merger.

                                      I-35
   42

          Tax Consequences to WABCO Shareholders. For federal income tax
     purposes, (1) no gain or loss will be recognized by the shareholders of
     WABCO upon the conversion of their shares of WABCO common stock into shares
     of MotivePower common stock pursuant to the merger, except with respect to
     cash, if any, received in lieu of fractional shares of MotivePower common
     stock, (2) the aggregate tax basis of the shares of MotivePower common
     stock received in exchange for shares of WABCO common stock pursuant to the
     merger, including a fractional share of MotivePower common stock for which
     cash is paid, will be the same as the aggregate tax basis of those shares
     of WABCO common stock, (3) the holding period for shares of MotivePower
     common stock received in exchange for shares of WABCO common stock pursuant
     to the merger will include the holder's holding period for those shares of
     WABCO common stock, provided those shares of WABCO common stock were held
     as capital assets by the holder at the effective time of the merger, and
     (4) a shareholder of WABCO who receives cash in lieu of a fractional share
     of MotivePower common stock will recognize gain or loss equal to the
     difference, if any, between that shareholder's basis in the fractional
     share (determined under clause (2) above) and the amount of cash received.

     The opinions described above may not apply to individuals who received
WABCO common stock as compensation or to shareholders who or which, for United
States federal income tax purposes, are nonresident alien individuals, foreign
corporations, foreign partnerships, foreign trusts or foreign estates.

     Moreover, the opinions described above will be based on some assumptions,
and both Sidley & Austin and Kirkland & Ellis will receive and rely upon
representations, unverified by counsel, contained in certificates of
MotivePower, WABCO and possibly others. The inaccuracy of any of those
assumptions or representations might jeopardize the validity of the opinions
rendered. Those opinions will neither bind the IRS nor preclude the IRS from
adopting positions contrary to those expressed above, and no assurance can be
given that contrary positions will not be successfully asserted by the IRS or
adopted by a court if the issues are litigated. Neither MotivePower nor WABCO
intends to obtain a ruling from the IRS with respect to the tax consequences of
the merger.

     Under the merger agreement, WABCO or, after the effective time of the
merger, MotivePower, as the surviving corporation, on behalf of WABCO, will pay
or cause to be paid any real property transfer, gains or similar taxes imposed
as a result of the merger. Although the matter is not free from doubt, because
of the absence of legislative, judicial or administrative, or other authority
directly on point, in the event that the WABCO shareholders are held to be
liable for any transfer and gains taxes, payment of such taxes by WABCO or
MotivePower, as the surviving corporation, on behalf of WABCO might be
characterized as a dividend taxable to the WABCO shareholders for federal income
tax purposes.

     WE INTEND THIS DISCUSSION TO PROVIDE ONLY A SUMMARY OF THE MATERIAL FEDERAL
INCOME TAX CONSEQUENCES OF THE MERGER. WE DO NOT INTEND THAT IT BE A COMPLETE
ANALYSIS OR DESCRIPTION OF ALL POTENTIAL FEDERAL INCOME TAX CONSEQUENCES OF THE
MERGER. IN ADDITION, AS NOTED ABOVE, WE DO NOT ADDRESS TAX CONSEQUENCES WHICH
MAY VARY WITH, OR ARE CONTINGENT UPON, INDIVIDUAL CIRCUMSTANCES. WE STRONGLY
URGE YOU TO CONSULT YOUR TAX ADVISOR TO DETERMINE YOUR PARTICULAR UNITED STATES
FEDERAL, STATE, LOCAL OR FOREIGN INCOME OR OTHER TAX CONSEQUENCES RESULTING FROM
THE MERGER, IN LIGHT OF YOUR INDIVIDUAL CIRCUMSTANCES.

REGULATORY MATTERS

     U.S. Antitrust. Under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended, and the related rules, the merger may not be completed until
notifications have been given, required information has been furnished to the
FTC and specified waiting period requirements have been satisfied. On June 22,
1999 MotivePower and WABCO each filed the required notification and report forms
under the HSR Act with the FTC and the Antitrust Division of the United States
Department of Justice. On July 19, 1999, MotivePower and WABCO received notice
of early termination of the waiting period under the HSR Act. At any time before
or after the consummation of the merger, the FTC could take action under the
antitrust laws as it deems necessary or desirable in the public interest,
including seeking to enjoin the consummation of the merger or seeking
divestiture of substantial assets of MotivePower and WABCO. At any time before
or after

                                      I-36
   43

the consummation of the merger and notwithstanding that the HSR Act waiting
period has expired, any state could take action under the antitrust laws as it
deems necessary or desirable for the public interest. This action could include
seeking to enjoin the consummation of the merger or seeking divestiture of WABCO
or businesses of MotivePower or WABCO. Private parties may also seek to take
legal action under the antitrust laws under specified circumstances.

     Other Laws. MotivePower and WABCO conduct operations in a number of
jurisdictions where other regulatory filings or approvals may be required or
advisable in connection with the completion of the merger. MotivePower and WABCO
are currently in the process of reviewing whether other filings or approvals may
be required or desirable in these other jurisdictions. We recognize that some of
these filings may not be completed before the closing, and that some of these
approvals, which are not as a matter of practice required to be obtained prior
to effectiveness of a merger transaction, may not be obtained prior to the
closing.

APPRAISAL RIGHTS

     Holders of MotivePower common stock are not entitled to dissenters'
appraisal rights under Pennsylvania law in connection with the merger. Holders
of WABCO common stock are not entitled to dissenters' appraisal rights under
Delaware law in connection with the merger because the shares of MotivePower
common stock that they will be entitled to receive in the merger will be listed
on the NYSE at the closing. See " -- Comparison of Shareholder
Rights -- Appraisal Rights" on page II-8.

FEDERAL SECURITIES LAWS CONSEQUENCES; STOCK TRANSFER RESTRICTION AGREEMENTS

     This joint proxy statement/prospectus does not cover any resales of the
MotivePower common stock to be received by the shareholders of WABCO upon
completion of the merger, and no person is authorized to make any use of this
joint proxy statement/prospectus in connection with any resale.

     All shares of MotivePower common stock received by WABCO shareholders in
the merger will be freely transferable, except that shares of MotivePower common
stock received by persons who are deemed to be "affiliates" of WABCO under the
Securities Act of 1933, as amended, at the time of the WABCO meeting may be
resold by them only in transactions permitted by Rule 145 under the 1933 Act or
as otherwise permitted under the 1933 Act. Persons who may be deemed to be
affiliates of WABCO for these purposes generally include individuals or entities
that control, are controlled by or are under common control with WABCO and
include directors and executive officers of WABCO. The merger agreement requires
WABCO to use its reasonable best efforts to cause each affiliate to execute a
written agreement to the effect that they will not offer, sell or otherwise
dispose of any of the shares of MotivePower common stock issued to them in the
merger in violation of the 1933 Act or the related SEC rules.

     In addition, each of the directors and some of the executive officers of
MotivePower and WABCO have executed written agreements prohibiting them from
selling, transferring or otherwise disposing of, or acquiring or selling any
options or other securities relating to, securities of MotivePower or WABCO that
would be intended to reduce the individual's risk relative to any shares of
MotivePower common stock or WABCO common stock beneficially owned by him or her
during the period beginning 30 days prior to the closing and ending at the time
when financial results covering at least 30 days of combined operations of
MotivePower and WABCO have been publicly released by MotivePower after the
merger.

          COMPARATIVE PER SHARE MARKET PRICE AND DIVIDEND INFORMATION

     MotivePower common stock and WABCO common stock are each listed on the
NYSE. MotivePower's ticker symbol on the NYSE is "MPO" and WABCO's ticker symbol
on the NYSE is "WAB." The following table shows, for the periods indicated, the
high and low of the last reported closing prices per share of MotivePower common
stock and WABCO common stock, as reported on the Consolidated Tape, and the
dividends per share. The MotivePower information has been restated to reflect
the effects of a three-for-two common stock split in the form of a 50 percent
stock dividend effective April 2, 1999.

     On June 2, 1999, the last full trading day before the public announcement
of the proposed merger, the last reported closing price was $16.63 for
MotivePower common stock and $23.31 for WABCO common stock. On July 19, 1999,
the most recent practicable date prior to the printing of this joint proxy
statement/prospectus, the last reported closing price was $18.06 for MotivePower
common stock and $23.13 for WABCO common stock. We urge you to obtain current
market quotations prior to making any decision with respect to the merger.

     Following the merger, MotivePower common stock will be traded on the NYSE
under the ticker symbol "MPO."

     The merger agreement permits WABCO to pay, prior to the closing, regular
quarterly cash dividends to shareholders. MotivePower has not historically paid
a dividend.

     After completion of the merger, the combined company's Board will review
and vote on whether to pay a quarterly dividend on the combined company's common
stock. We advise WABCO shareholders that the Board may choose to no longer pay a
dividend on your shares.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

     The following unaudited pro forma condensed combined financial statements
combine the historical consolidated balance sheets and statements of income of
MotivePower and WABCO giving effect to the merger using the pooling of interests
method of accounting for a business combination.

     We are providing the following information to aid you in your analysis of
the financial aspects of the merger. We derived this information from the
audited consolidated financial statements of MotivePower for the years ended
December 31, 1998, 1997 and 1996 and the unaudited consolidated financial
statements for the three months ended March 31, 1999 and 1998 and from the
audited consolidated financial statements of WABCO for the years ended December
31, 1998, 1997 and 1996 and the unaudited consolidated financial statements for
the three months ended March 31, 1999 and 1998. The information is only a
summary and you should read it in conjunction with our historical financial
statements and related notes contained in the annual reports and other
information that we have filed with the SEC. See "Where You Can Find More
Information" on page III-1.

     The unaudited pro forma condensed combined statements of income for the
years ended December 31, 1998, 1997 and 1996 and for the three months ended
March 31, 1999 and 1998 assume the merger was effected on January 1, 1996. The
unaudited pro forma condensed combined balance sheet gives effect to the merger
as if it had occurred on March 31, 1999. The accounting policies of MotivePower
and WABCO are substantially comparable. However, adjustments were made to
conform the classification of amortization expense and income taxes receivable
in the unaudited pro forma condensed combined financial statements.

     The unaudited pro forma combined financial information is for illustrative
purposes only. The MotivePower and WABCO combined company may have performed
differently had they always been combined. The unaudited pro forma condensed
combined financial information may not be indicative of the historical results
that would have been achieved had the companies always been combined or the
future results that the combined company will experience after the merger.

                NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED
                              FINANCIAL STATEMENTS

Note 1.  Basis of Presentation

     The unaudited pro forma condensed combined statements of income are based
on the consolidated financial statements of MotivePower and WABCO for the years
ended December 31, 1998, 1997 and 1996 and for the three months ended March 31,
1999 and 1998. The unaudited pro forma condensed combined balance sheet is based
on the consolidated financial statements of MotivePower and WABCO at March 31,
1999.

     MotivePower and WABCO consolidated financial statements are prepared in
conformity with generally accepted accounting principles and require MotivePower
and WABCO management to make estimates that affect the reported amounts of
assets, liabilities, revenues and expenses and the disclosure of contingent
assets and liabilities. In the opinion of MotivePower and WABCO, the unaudited
pro forma condensed combined financial statements include all adjustments
necessary to present fairly the results of the periods presented. Actual results
are not expected to differ materially from these estimates.

Note 2.  Accounting Policies and Financial Statement Classifications

     The accounting policies of MotivePower and WABCO are substantially
comparable. The unaudited pro forma combined condensed statements of income
reflect reclassification adjustments to conform to the presentation of
amortization expense. The unaudited pro forma combined condensed balance sheet
reflects a reclassification adjustment to conform the presentation of income
taxes receivable and payable.

     Certain revenues, costs and other deductions in the consolidated statements
of income for MotivePower and WABCO have been reclassified to conform to the
line item presentation in the pro forma condensed combined statements of income.
Certain assets and liabilities in the consolidated balance sheets for
MotivePower and WABCO have been reclassified to conform to the line item
presentation in the pro forma condensed combined balance sheet.

Note 3.  Earnings Per Share (as reported), Pro Forma Earnings Per Share and
Dividends Per Share

     The MotivePower earnings per share (as reported) have been restated to
reflect a three-for-two common stock split in the form of a 50 percent stock
dividend effective April 2, 1999.

     The pro forma combined income before extraordinary item per common share is
based on income before extraordinary item and the weighted average number of
outstanding common shares. Income before extraordinary item per common
share - diluted includes the dilutive effect of stock options and restricted
stock awards. The pro forma combined weighted average number of outstanding
common shares has been adjusted to reflect the exchange ratio of 1.3 shares of
MotivePower common stock for each share of WABCO common stock.

     The pro forma combined dividends per share reflect the sum of the dividends
paid by MotivePower and WABCO divided by the number of shares that would have
been outstanding for the periods, after adjusting the WABCO shares for the
exchange ratio of 1.3 shares of MotivePower common stock.

Note 4.  Intercompany Transactions

     Intercompany sales and purchase transactions were not material between the
two companies and therefore are not reflected as adjustments to the unaudited
pro forma condensed combined financial statements.

                                      I-46

Note 5.  Merger-Related and Integration-Related Expenses

     Merger-related fees and expenses, consisting primarily of SEC filing fees,
fees and expenses of investment bankers, attorneys and accountants, and
financial printing and other related charges, are estimated to be approximately
$20-25 million.

     We estimate that costs of approximately $35-40 million will be incurred for
severance and other integration-related expenses, including the elimination of
duplicate facilities and excess capacity, operational realignment and related
workforce reductions. These expenditures are necessary to reduce costs and
operate efficiently. The unaudited pro forma condensed combined financial
statements do not reflect the benefits from the expected synergies.

     A one-time pooling-related charge of $41 million has been reflected in the
Unaudited Pro Forma Condensed Combined Balance Sheet as of March 31, 1999 and is
not reflected in the Unaudited Pro Forma Condensed Combined Statements of Income
due to its non-recurring nature. The $41 million charge was based on the maximum
estimate of the costs of merger-related and integration-related expenses, net of
a 37% tax effect.

Note 6.  Other Pro Forma Adjustments

     A pro forma adjustment has been made to reflect the cancellation of WABCO
common stock accounted for as treasury stock and the assumed issuance of
MotivePower common stock in exchange for all of the outstanding WABCO common
stock based on the exchange ratio of 1.3. The actual number of shares of
MotivePower common stock to be issued in connection with the merger will be
based on the number of shares of WABCO common stock issued and outstanding at
the effective time.

                         OPINIONS OF FINANCIAL ADVISORS

     We each retained our own financial advisor to assist us and our Boards in
our consideration of valuation, financial and other matters relating to the
merger. MotivePower retained Wasserstein Perella & Co., Inc. as its financial
advisor, and WABCO retained Credit Suisse First Boston Corporation as its
financial advisor.

OPINION OF MOTIVEPOWER FINANCIAL ADVISOR

     The MotivePower Board retained Wasserstein Perella to provide requested
investment banking advice and services in connection with a possible business
combination between MotivePower and WABCO, including rendering its opinion as to
the fairness, from a financial point of view, of the exchange ratio to
MotivePower. Wasserstein Perella was not requested to recommend the amount of
consideration to be paid; it was requested to evaluate, among other things, the
fairness of the exchange ratio which MotivePower and WABCO negotiated.

     On June 2, 1999, Wasserstein Perella orally delivered its opinion to the
MotivePower Board, which it later confirmed in a written opinion dated June 2,
1999, to the effect that, as of the date of the opinion and based upon specified
assumptions, the exchange ratio in the merger is fair, from a financial point of
view, to MotivePower. Wasserstein Perella also presented to the MotivePower
Board the analyses described below.

     A COPY OF WASSERSTEIN PERELLA'S OPINION IS ATTACHED AS ANNEX D TO THIS
JOINT PROXY STATEMENT/PROSPECTUS. SHAREHOLDERS ARE URGED TO READ THE WASSERSTEIN
PERELLA OPINION IN ITS ENTIRETY FOR INFORMATION WITH RESPECT TO THE PROCEDURES
FOLLOWED, ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITS OF THE REVIEW BY
WASSERSTEIN PERELLA IN RENDERING ITS OPINION. REFERENCES TO WASSERSTEIN
PERELLA'S OPINION IN THIS JOINT PROXY STATEMENT/PROSPECTUS AND THE SUMMARY OF
WASSERSTEIN PERELLA'S OPINION IN THIS SECTION OF THE JOINT PROXY
STATEMENT/PROSPECTUS ARE QUALIFIED BY REFERENCE TO THE FULL TEXT OF WASSERSTEIN
PERELLA'S OPINION. WASSERSTEIN PERELLA'S OPINION ONLY ADDRESSES THE FAIRNESS,
FROM A FINANCIAL POINT OF VIEW, OF THE EXCHANGE RATIO TO MOTIVEPOWER AND IT DOES
NOT ADDRESS ANY OTHER ASPECT OF THE MERGER. WASSERSTEIN PERELLA'S OPINION DOES
NOT CONSTITUTE A RECOMMENDATION TO SHAREHOLDERS TO VOTE IN FAVOR OF THE MERGER
AND SHAREHOLDERS SHOULD NOT RELY UPON IT AS A RECOMMENDATION.

     In arriving at its opinion, Wasserstein Perella reviewed, among other
things,

     - the merger agreement;

     - certain publicly available business and financial information relating to
       MotivePower and WABCO which Wasserstein Perella deemed to be relevant;

     - certain internal non-public financial and operating information,
       including certain budgeted cashflow information and analyses prepared by
       or on behalf of MotivePower and WABCO and provided orally or in writing
       by or on behalf of the managements of MotivePower and WABCO to
       Wasserstein Perella for purposes of its analysis;

     - certain financial and stock market data relating to MotivePower and
       WABCO, and compared this data with similar data for certain other
       companies, the securities of which are publicly traded, that Wasserstein
       Perella deemed to be relevant;

     - the financial terms of the merger, and compared these terms with the
       financial terms of certain other transactions in the rail supply and
       service industry which Wasserstein Perella deemed to be relevant to its
       inquiry; and

     - the potential pro forma impact of the merger.

     Wasserstein Perella had discussions with the managements of MotivePower and
WABCO and their representatives about the respective businesses, operations,
assets, financial condition and future prospects of MotivePower and WABCO.
Wasserstein Perella also performed such studies, analyses and investigations and
reviewed other information as it considered appropriate for purposes of arriving
at and preparing its opinion.

     In conducting its analysis and arriving at its opinion, Wasserstein Perella
assumed and relied upon the accuracy and completeness of all financial and other
information that was provided to or discussed with it or was publicly available,
and did not assume any responsibility for independently verifying this
information. Wasserstein Perella also relied upon the reasonableness and
accuracy of the financial information and analyses provided to them and assumed
that all financial information and analyses provided by MotivePower and WABCO
were prepared in good faith and on bases reflecting the best currently available
judgments and estimates of the respective managements of MotivePower and WABCO.
Wasserstein Perella did not express any opinion with respect to such financial
information and analyses or the assumptions upon which they are based. In
addition, Wasserstein Perella did not review any of the books and records of
MotivePower or WABCO, except as described above, or assume any responsibility
for conducting a physical inspection of the properties or facilities of
MotivePower or WABCO, or for making or obtaining an independent valuation or
appraisal of the assets or liabilities of MotivePower or WABCO, and Wasserstein
Perella was not provided with any such independent valuation or appraisal.
Wasserstein Perella noted that the merger is intended to qualify as a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
and Wasserstein Perella assumed that the merger will qualify as such a
reorganization. Wasserstein Perella also assumed that the transactions described
in the merger agreement would be consummated on the terms set forth in the
merger agreement, without material waiver or modification.

     Wasserstein Perella's opinion was necessarily based on economic and market
conditions and other circumstances as they existed and could be evaluated by
Wasserstein Perella on the date of its opinion. In addition, Wasserstein Perella
did not express any opinion as to the price or trading range at which the
MotivePower common stock will trade following the merger.

     Summary and Analysis of the Merger

     During a June 2, 1999 teleconference with the MotivePower Board, and
supported by materials presented to the MotivePower Board dated June 1, 1999,
Wasserstein Perella reviewed with the members of the MotivePower Board certain
financial, industry and market information with respect to MotivePower and
WABCO, and the procedures used in arriving at, and the analyses underlying,
Wasserstein Perella's opinion. The following summary is not a complete
description of Wasserstein Perella's opinion or of Wasserstein Perella's
analyses relating to its opinion. The preparation of a fairness opinion is a
complex process that is
                                      I-48
   55

not purely mathematical and is not necessarily susceptible to partial analyses
or summary description. Shareholders are encouraged to review Wasserstein
Perella's opinion in its entirety.

     Wasserstein Perella presented a summary of the material terms of the
merger, including:

     - the fact that the merger was a stock-for-stock transaction intended to be
       a tax-free exchange of common stock;

     - the exchange ratio;

     - the conversion of WABCO options into options to purchase MotivePower
       common stock;

     - the merger's effect on WABCO's ESOP;

     - the increase of the MotivePower Board from seven members to fourteen,
       with MotivePower and WABCO each designating seven members; and

     - customary conditions to closing.

     MotivePower and WABCO Historical Stock Price Ratios and Trading Analysis

     Wasserstein Perella reviewed the ratio of the closing price per share of
WABCO common stock to the closing price per share of MotivePower common stock
over the 90-day period, the 60-day period, the 30-day period and the 7-day
period before May 28, 1999, based on actual trading days. Wasserstein Perella
noted that the mean of the ratios of the closing price per share of WABCO common
stock to the closing price per share of MotivePower common stock for these
periods were 1.13x, 1.22x, 1.20x and 1.28x, respectively. Wasserstein Perella
also noted that the ratio of the closing price per share of WABCO common stock
to the closing price per share of MotivePower common stock for May 28, 1999 was
1.35x.

     Wasserstein Perella also performed an analysis of the market trading
multiples as of May 28, 1999 for MotivePower and WABCO based on (1) their
enterprise values as a multiple of 1999 estimated sales, earnings before
interest, taxes, amortization and depreciation ("EBITDA") and earnings before
interest and taxes ("EBIT") and (2) their equity values as a multiple of 1999
estimated net income and book value.

     Based on these calculations, Wasserstein Perella noted that (1) the
enterprise value market multiples for MotivePower were 1.3x for 1999 estimated
sales, 7.3x for 1999 estimated EBITDA and 9.2x for 1999 estimated EBIT; and (2)
the equity value market multiples were 12.7x for 1999 estimated net income and
2.2x for 1999 estimated book value. For WABCO, (1) the enterprise value market
multiples were 1.5x for 1999 estimated sales, 7.0x for 1999 estimated EBITDA and
8.6x for 1999 estimated EBIT; and (2) the equity value market multiples were
10.8x for 1999 estimated net income and 25.4x for 1999 estimated book value.

     Wasserstein Perella analyzed the historical daily ratios and market trading
multiples of MotivePower and WABCO as part of its analysis of the fairness of
the exchange ratio from a financial point of view to MotivePower. Wasserstein
Perella did not determine a range of implied public market equity values for
either MotivePower or WABCO based on these analyses.

     Analysis of the Exchange Ratio

     On June 2, 1999, Wasserstein Perella orally updated the materials which it
previously presented to MotivePower's Board and noted that the calculation of
the exchange ratio, based on the closing price of MotivePower common stock on
June 2, 1999, implied a consideration of $21.6125 per share of WABCO common
stock, a discount of 7.3% to the closing price of WABCO common stock on June 2,
1999, a market equity value of $557 million and an enterprise value of $1.02
billion and would result in a pro forma direct ownership of MotivePower
following the completion of the merger by the current shareholders of
MotivePower of 45.2%, excluding shares of common stock held by WABCO's ESOP, and
38.3% including shares of common stock held by WABCO's ESOP. Wasserstein Perella
reviewed the structure of the exchange ratio with the MotivePower Board.
Wasserstein Perella also noted that increases or decreases in the price of
MotivePower common stock before the completion of the merger would not affect
the pro forma percentage ownership of MotivePower after the completion of the
merger by the current shareholders of MotivePower.

     Pro Forma Transaction Analysis

     Wasserstein Perella analyzed the potential pro forma effect of the merger
on earnings per share with respect to the shareholders of MotivePower for the
fiscal years 1999 through 2001, using the MotivePower management case and the
WABCO management case, assuming qualification of the merger for pooling-of-
interests accounting treatment and the achievement of the per-year synergy
levels estimated by MotivePower and WABCO managements. This analysis suggested
that, with respect to MotivePower's shareholders, the merger would be accretive
to earnings per share in fiscal years 1999, 2000 and 2001. The actual results
that the combined company achieves may, however, vary from projected results and
these variations may be material.

     Contribution Analysis

     Wasserstein Perella compared the relative contributions of the implied
equity value of MotivePower and WABCO to the combined entity based on the last
twelve months ("LTM") and 1999 estimated net income, EBITDA and EBIT. Based on
the median LTM comparable trading multiples, financial data and the implied
equity values, MotivePower's relative contributions were 41.1%, 41.7% and 39.7%,
respectively, and based on the median 1999 estimated comparable trading
multiples, financial data and the implied equity values, MotivePower's relative
contributions were 40.3%, 43.7% and 42.1%, respectively.

     Selected Rail Supply and Services Company Trading Analysis

     To analyze the relative public market valuations of selected comparable
rail supply and services companies, Wasserstein Perella analyzed the stock price
performance and operating performance of MotivePower, WABCO, ABC-NACO Inc.,
Greenbrier Companies, Harmon Industries, Inc., L.B. Foster Co., Trinity
Industries, Inc. and Varlen Corp. Wasserstein Perella calculated market trading
multiples for each of these companies based on their (1) enterprise values as a
multiple of LTM sales, next fiscal year ("NFY") sales, LTM EBITDA, NFY EBITDA,
LTM EBIT and NFY EBIT and (2) equity values as a multiple of LTM net income, NFY
net income, LTM book value and NFY book value.

     Based on these calculations, Wasserstein Perella noted that the range of
enterprise value market multiples was 0.4x to 1.1x for LTM sales, 0.5x to 1.1x
for NFY sales, 4.4x to 10.4x for LTM EBITDA, 4.0x to 8.2x for NFY EBITDA, 5.2x
to 14.3x for LTM EBIT and 5.1x to 15.1x for NFY EBIT. The range of equity value
market multiples was 6.8x to 19.4x for LTM net income, 7.3x to 24.1x for NFY net
income, 0.7x to 2.8x for LTM book value and 1.0x to 2.6x for NFY book value.
Based on this range of enterprise value market multiples and equity value market
multiples, Wasserstein Perella noted that the exchange ratio was within or above
the foregoing valuation range and that this fact supported a determination that
the exchange ratio was fair to MotivePower.

     Review of Selected Rail Supply and Services Company Acquisitions

     Wasserstein Perella reviewed certain publicly available financial and other
information relating to the following recently announced business combinations
in the rail supply and services business: Amsted Industries/Varlen Corp.
(pending), MotivePower/Young Radiator Company, Trinity Industries, Inc./MCT
Holding, WABCO/Rockwell Collins, ABC Rail Products/NACO, Rail Acquisition
Corp./Portec Inc., Finmeccanica S.p.A./Union Switch & Signal, WABCO/Vapor Corp.,
Varlen Corp./Brenco, Trinity Industries, Inc./Transcisco Industries, Inc.,
Trinity plc/ML Douglas & Schopf Maschinenbau, ABC Rail Products Corp./ GE
Railcar Wheel & Parts Services Corp., Harmon Industries, Inc./Transportation
Division and Dimeling, Schreiber & Park/VMV Enterprise Inc. In conducting its
review of each of these transactions, Wasserstein Perella calculated the equity
purchase price transaction multiple as a multiple of LTM net income for the
calendar year in which the applicable transaction was announced, based on the
latest publicly available information as of the date of each such transaction.

     Based on these calculations, Wasserstein Perella noted that the range of
implied enterprise value market multiples was 0.5x to 1.8x of LTM sales, 4.6x to
21.0x of LTM EBITDA and 7.5x to 11.8x of LTM EBIT for the calendar year in which
the applicable transaction was announced. The range of implied equity value
                                      I-50
   57

market multiples was 9.7x to 33.1x of LTM net income for the calendar year in
which the applicable transaction was announced. Based on this range of implied
enterprise value market multiples and implied equity value market multiples,
Wasserstein Perella noted that the exchange ratio was within or above the
foregoing valuation range and that this fact supported a determination that the
exchange ratio was fair to MotivePower.

     Discounted Cash Flow Analysis

     Wasserstein Perella performed discounted cash flow analyses for MotivePower
and WABCO using financial projections for fiscal years 1999 through 2003
provided by the respective management of MotivePower and WABCO. MotivePower's
and WABCO's respective management each prepared a set of financial projections
which were based on each management's base assumptions for future performance.
Wasserstein Perella aggregated the present value of the cash flows from 1999
through 2003 with the present value of a range of terminal values. All cash
flows were discounted at rates of 10.0%, 11.0% and 12.0%. The terminal values
were computed using multiples of 6.0x. 7.0x and 8.0x for fiscal year 2003
EBITDA. Wasserstein Perella arrived at these discount rates based on its
judgment of the weighted average cost of capital of selected publicly-traded
rail supply and service companies, and arrived at these terminal values based on
its review of the trading characteristics of the common stock of selected
publicly-traded rail supply and service companies. This analysis indicated a
range of values for the MotivePower common stock of $15.09 and $21.21 per share
with a midpoint of $18.15 per share, and a range of values for WABCO common
stock of $25.68 and $39.75 per share with a midpoint of $32.72 per share. Based
on this range of implied share prices, Wasserstein Perella noted that the
exchange ratio was within or above the foregoing valuation range and that this
fact supported a determination that the exchange ratio was fair to MotivePower.

     Premiums Analysis

     Wasserstein Perella reviewed 25 announced transactions from January 22,
1996 through January 18, 1999 involving mergers of equals of publicly-held
companies where transaction values were greater than $500 million to derive a
range of premiums paid over the public trading prices one day, one week and four
weeks before the announcement of each transaction. In connection with this
analysis, Wasserstein Perella noted, among other things, that (1) the reasons
for, and circumstances surrounding, each of the transactions analyzed were
diverse, (2) the characteristics of the companies involved were not necessarily
comparable to those of MotivePower and WABCO and (3) premiums fluctuate based on
perceived growth, synergies, strategic value, the type of consideration utilized
in the transaction, information in the securities markets and other factors.

     Wasserstein Perella's premiums analyses indicated that the medians of
premiums paid in the transactions over the public per share trading prices one
day, one week and four weeks before the announcement were 6.4%, 10.7% and 13.8%,
respectively, and that the means of premiums paid in the transactions over the
public per share trading prices one day, one week and four weeks before the
announcement were 8.1%, 11.5%, and 15.2%. Based on this range of implied
premiums, Wasserstein Perella noted that the exchange ratio was within or above
the foregoing valuation range and that this fact supported a determination that
the exchange ratio was fair to MotivePower.

     Summary

     The preceding summary is not a complete description of the analyses
performed by Wasserstein Perella or its presentations to the MotivePower Board.
Wasserstein Perella believes that its analyses must be considered as a whole and
that selecting portions of its analyses and the factors considered by it,
without considering all factors and analyses, could create a misleading view of
the process underlying its analyses set forth in its opinion. In performing its
analyses, Wasserstein Perella made numerous macroeconomic, operating and
financial assumptions with respect to industry performance, general business,
regulatory and economic conditions and other matters, many of which are beyond
the control of MotivePower and WABCO. Any estimates incorporated in the analyses
performed by Wasserstein Perella are not necessarily indicative of actual past
or future results or values, which may be significantly more or less favorable
than these estimates.
                                      I-51
   58

Estimated values do not purport to be appraisals and do not necessarily reflect
the prices at which rail supply and services companies may be sold. Since these
estimates are inherently subject to uncertainty, Wasserstein Perella does not
assume any responsibility for their accuracy. No company analyzed for
comparative purposes is identical to MotivePower or WABCO. Accordingly, an
analysis of comparative companies and comparative business combinations is not
simply mathematical, but rather involves complex considerations and judgments
concerning financial and operating characteristics of the companies involved and
other factors that affect value.

     In addition to the analyses outlined above, Wasserstein Perella performed
other valuation analyses which it deemed appropriate in determining the fairness
of the exchange ratio from a financial point of view to MotivePower. Wasserstein
Perella concluded that, in its judgment, including the full range of its
analyses described above, the exchange ratio is fair, from a financial point of
view, to MotivePower.

     Wasserstein Perella is an investment banking firm engaged in, among other
things, the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for corporate and other purposes. The MotivePower Board selected
Wasserstein Perella as its financial advisor because Wasserstein Perella is an
internationally recognized investment banking firm, and members of Wasserstein
Perella have substantial experience in transactions such as the merger and in
the valuation of companies.

     MotivePower agreed to pay Wasserstein Perella (1) a monthly financial
advisory fee of $20,000 as of April 14, 1999 through the date of either the
termination or successful consummation of the merger and (2) a fee of $5.24
million contingent upon the successful consummation of the merger, against which
the monthly financial advisory fee will be credited. In addition, MotivePower
agreed to reimburse Wasserstein Perella for its reasonable out-of-pocket
expenses related to its engagement, including the reasonable fees and expenses
of counsel, whether or not the merger is consummated. MotivePower also has
agreed to indemnify Wasserstein Perella and certain related persons against
certain liabilities relating to or arising out of its engagement, including
certain liabilities under the federal securities laws. In the past, Wasserstein
Perella has provided financial advisory services to MotivePower and received
compensation for its services.

     In the ordinary course of its business, Wasserstein Perella may actively
trade the securities of MotivePower and, before completion of the merger, WABCO
for the accounts of Wasserstein Perella and for the accounts of its customers
and, accordingly, may at any time hold a long or short position in such
securities.

OPINION OF WABCO FINANCIAL ADVISOR

     CSFB has acted as financial advisor to WABCO in connection with the merger.
WABCO selected CSFB based on CSFB's experience, expertise and familiarity with
WABCO and its business. CSFB is an internationally recognized investment banking
firm and is regularly engaged in the valuation of businesses and securities in
connection with mergers and acquisitions, leveraged buyouts, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for corporate and other
purposes.

     At meetings of the WABCO Board on May 18, 1999 and June 1, 1999,
representatives of CSFB made presentations regarding the valuation analyses
performed by it in connection with the merger. On June 2, 1999, CSFB orally
delivered its opinion, subsequently delivered in writing, that, as of June 2,
1999 and based upon and subject to the matters set forth in that opinion, the
exchange ratio was fair from a financial point of view to the WABCO
shareholders. CSFB has consented to the inclusion of the CSFB opinion as Annex E
to this joint proxy statement/prospectus.

     WE HAVE ATTACHED THE FULL TEXT OF THE CSFB OPINION, WHICH SETS FORTH THE
PROCEDURES FOLLOWED, ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE
REVIEW UNDERTAKEN AS ANNEX E TO THIS JOINT PROXY STATEMENT/PROSPECTUS. THE CSFB
OPINION IS DIRECTED TO THE WABCO BOARD AND RELATES ONLY TO THE FAIRNESS FROM A
FINANCIAL POINT OF VIEW OF THE EXCHANGE RATIO TO THE WABCO SHAREHOLDERS, DOES

                                      I-52
   59

NOT ADDRESS ANY OTHER ASPECT OF THE MERGER AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY WABCO SHAREHOLDER AS TO WHETHER SUCH WABCO SHAREHOLDER
SHOULD APPROVE THE MERGER. THIS SECTION INCLUDES ONLY A SUMMARY OF THE CSFB
OPINION AND, AS A SUMMARY, IT IS NOT A SUBSTITUTE FOR THE FULL TEXT OF THE
OPINION. WE URGE THE WABCO SHAREHOLDERS TO READ THE CSFB OPINION IN ITS
ENTIRETY.

     In arriving at its opinion, CSFB reviewed certain publicly available
business and financial information relating to WABCO and MotivePower, as well as
the merger agreement. CSFB also reviewed certain other information, including
financial forecasts and estimates of the cost savings and other potential
synergies anticipated to result from the merger, provided to it by WABCO and
MotivePower, and met with the managements of WABCO and MotivePower to discuss
the business and prospects of WABCO and MotivePower. CSFB also relied upon the
views of WABCO's and MotivePower's managements concerning the business,
operational and strategic benefits and implications of the merger.

     CSFB also considered certain financial and stock market data of WABCO and
MotivePower and compared that data with similar data for other publicly held
companies in businesses similar to that of WABCO and MotivePower. CSFB also
considered the financial terms of certain other business combinations and other
transactions that have recently been effected. CSFB also considered such other
information, financial studies, analyses, and investigations and financial,
economic and market criteria as CSFB deemed relevant.

     In connection with its review, CSFB did not assume any responsibility for
independent verification of any of the foregoing information and relied on such
information being complete and accurate in all material respects. With respect
to the financial forecasts, CSFB assumed that they have been reasonably prepared
on bases reflecting the best currently available estimates and judgments of the
managements of WABCO and MotivePower as to the future financial performance of
their respective companies and as to the cost savings and other potential
synergies anticipated to result from the merger. In addition, CSFB was not
requested to make and did not make an independent evaluation or appraisal of the
assets or liabilities, contingent or otherwise, of WABCO or MotivePower, nor was
CSFB furnished with any such evaluation or appraisal. Furthermore, CSFB assumed
that the merger will qualify for pooling of interests accounting treatment and
as a reorganization within the meaning of Section 368(a) of the Internal Revenue
Code.

     CSFB was not requested to, and did not, solicit third party indications of
interest in acquiring all or any part of WABCO.

     CSFB necessarily based its opinion upon financial, economic, market and
other conditions as they existed and could be evaluated on the date of the CSFB
opinion. CSFB did not express any opinion as to what the actual value of
MotivePower common stock will be when issued to shareholders of WABCO pursuant
to the merger or the prices at which such shares of MotivePower common stock
will trade subsequent to the merger.

     In preparing the CSFB opinion, CSFB performed a variety of financial and
comparative analyses. The preparation of a fairness opinion is a complex
analytical process involving various determinations as to the most appropriate
and relevant methods of financial analyses and the application of those methods
to the particular circumstances and, therefore, such an opinion is not readily
susceptible to summary description. In arriving at its opinion, CSFB made
qualitative judgments as to the significance and relevance of each analysis and
factor considered by it. Accordingly, CSFB believes that its analyses must be
considered as a whole and that selecting portions of its analyses and factors,
without considering all analyses and factors, could create a misleading or
incomplete view of the processes underlying those analyses and the CSFB opinion.
In its analyses, CSFB made numerous assumptions with respect to WABCO,
MotivePower, industry performance, regulatory, general business, economic,
market and financial conditions and other matters, many of which are beyond the
control of WABCO and MotivePower.

     The following is a summary of the material analyses and methodologies used
by CSFB to render its fairness opinion.

                                      I-53

     Valuation Analyses Used to Derive Implied Exchange Ratios

     CSFB prepared separate valuations of WABCO and MotivePower before
considering the pro forma impact of any cost savings, operating synergies or
strategic benefits resulting from the merger. In determining valuation, CSFB
used the following methodologies: Discounted Cash Flow Analysis, Comparable
Companies Analysis, Comparable Acquisitions Analysis, Contribution Analysis and
Historical Exchange Ratio Analysis. Each of these methodologies was used to
generate an implied exchange ratio reference range. CSFB has also analyzed the
potential pro forma effect of the merger on earnings per share. These various
valuation analyses are summarized below.

     The valuation methodologies noted above and the implied exchange ratio
ranges derived therefrom are described below. In applying the various valuation
methodologies to the particular businesses, operations and prospects of WABCO
and MotivePower, and the particular circumstances of the merger, CSFB made
qualitative judgments as to the significance and relevance of each analysis.
Moreover, no company, transaction or business used in the analyses as a
comparison is identical to WABCO or MotivePower or the merger, nor is an
evaluation of the results of the analyses entirely mathematical. Rather, those
analyses involve complex considerations and judgments concerning financial and
operating characteristics and other factors that could affect the acquisition,
public trading or other values of the companies, business segments, or
transactions being analyzed. The estimates contained in those analyses and the
ranges of valuations and implied exchange ratios resulting from any particular
analysis are not necessarily indicative of actual values or predictive of future
results or values, which may be significantly more or less favorable than those
suggested by the analyses. In addition, analyses relating to the value of
businesses or securities do not purport to be appraisals or to reflect the
prices at which businesses or securities actually may be sold. Accordingly,
those analyses and estimates are inherently subject to substantial uncertainty.
CSFB's financial analyses were only one of many factors the WABCO Board
considered in its evaluation of the merger and should not be viewed as
determinative of the views of the WABCO Board or management with respect to the
exchange ratio or the merger. ACCORDINGLY, THE METHODOLOGIES AND THE IMPLIED
EXCHANGE RATIOS DERIVED THEREFROM DESCRIBED BELOW MUST BE CONSIDERED AS A WHOLE
AND IN THE CONTEXT OF THE NARRATIVE DESCRIPTION OF THE FINANCIAL ANALYSES,
INCLUDING THE ASSUMPTIONS UNDERLYING THESE ANALYSES. CONSIDERING THE IMPLIED
EXCHANGE RATIOS SET FORTH BELOW WITHOUT CONSIDERING THE FULL NARRATIVE
DESCRIPTION OF THE FINANCIAL ANALYSES, INCLUDING THE ASSUMPTIONS UNDERLYING
THESE ANALYSES, COULD CREATE A MISLEADING OR INCOMPLETE VIEW OF THE PROCESS
UNDERLYING, AND CONCLUSIONS REPRESENTED BY, CSFB'S OPINION.

     Discounted Cash Flow Analysis

     WABCO Discounted Cash Flow Analysis. CSFB performed a discounted cash flow
("DCF") analysis of WABCO by calculating the present value of the sum of a
ten-year stream of unlevered free cash flows and a 2008 terminal value. CSFB's
analysis was based on two cases of WABCO management's projections for the years
1999 through 2001, the management case and a more conservative alternative case,
and an extension of those forecasts through 2008, developed on the basis of
projected growth rates. CSFB utilized a ten year forecast to perform the DCF
analysis in order to reflect the general business cycles. For both cases, CSFB
applied multiples which were based on companies and transactions in WABCO's
industry segments of EBITDA that ranged from 6.0 to 7.0 and discount rates,
based on the weighted average cost of capital for WABCO's industry segments, of
9.0% to 9.5%. CSFB did not consider cost savings and other potential synergies
anticipated to result from the merger.

     MotivePower Discounted Cash Flow Analysis. CSFB performed a DCF analysis of
MotivePower by calculating the present value of the sum of a ten-year stream of
unlevered free cash flows and a 2008 terminal value. MotivePower's analysis was
based on two cases of MotivePower managements' projections for the years 1999
through 2001, the management case and a more conservative alternative case, and
an extension of those forecasts through 2008, developed on the basis of
projected growth rates. CSFB utilized a ten year forecast to perform the DCF
analysis in order to reflect the general business cycles. For both cases, CSFB
applied multiples which were based on companies and transactions in
MotivePower's industry segments of EBITDA that ranged from 6.0 to 7.0 and
discount rates of 9.0% to 9.5%, based on the weighted

                                      I-54
   61

average cost of capital for MotivePower's industry segments. CSFB did not
consider cost savings and other potential synergies anticipated to result from
the merger.

     Based on the foregoing, the DCF analysis for WABCO and MotivePower resulted
in an implied exchange ratio reference range of 1.09 to 1.47.

     Comparable Companies Analysis

     CSFB compared certain financial information for WABCO and MotivePower
businesses to that of selected public companies, all of which CSFB selected
because, among other reasons, each serves markets generally similar to markets
WABCO and MotivePower serve, each had a meaningful number of published earnings
estimates, and each is considered to be reasonably comparable to the respective
WABCO and MotivePower business segments. CSFB considered the companies set forth
in the table below.

                               SELECTED COMPANIES



    COMPONENTS                                                              CAR BUILDERS
                                                                         
    Westinghouse Air Brake Company                                          Greenbrier Companies
    ABC-NACO                                                                Johnstown America
    Harmon Industries                                                       Trinity Industries
    MotivePower Industries
    Varlen Corporation


     CSFB compared the enterprise values, for purposes of this analysis, the sum
of market equity value and net debt, of the selected companies as multiples of
estimated fiscal 1999 EBITDA and EBIT and market equity values as multiples of
estimated fiscal 1999 net income. CSFB based estimated financial data for the
selected companies on estimates of equity research analysts. Based on these
analyses, CSFB derived a range of enterprise values as multiples of 1999
estimated EBITDA of 5.9 to 7.7 and a range of enterprise values as multiples of
1999 estimated EBIT of 8.6 to 9.4. The range of market equity values as
multiples of 1999 estimated net income was 10.9 to 14.1. These ranges were
derived from the selected components companies, as CSFB determined that the
business characteristics of the selected car builders were less comparable to
WABCO and MotivePower.

     CSFB then applied these multiples to the 1999 management estimates for
EBITDA and EBIT for each of WABCO and MotivePower. CSFB's analysis resulted in
an implied exchange ratio reference range of 1.13 to 1.80.

     Comparable Acquisitions Analysis

     CSFB analyzed the purchase prices and implied transaction multiples paid or
proposed to be paid in selected merger and acquisition transactions in the rail,
automotive and other electronic control and instrumentation segments, all of
which CSFB considered to be reasonably comparable to the respective WABCO and
MotivePower business segments. CSFB selected the acquisition transitions, among
other reasons, because the target of each transaction served markets generally
similar to markets WABCO and MotivePower serve. CSFB considered rail, automotive
and other electronic control and instrumentation transactions, including those
transactions set forth in the table below.

     CSFB compared enterprise values for the selected acquisitions as multiples
of revenues, EBITDA and EBIT. CSFB based all multiples on historical financial
information available at the time of the announcement of the selected
acquisitions. The table below sets forth the median, mean, high and low
multiples for the selected acquisitions.

EBIT........................................................  8.1    14.9    11.3     10.9


     CSFB applied selected ranges of multiples based on these multiples to 1999
estimated revenues, EBITDA and EBIT for each of WABCO and MotivePower. CSFB's
analysis resulted in an implied exchange ratio range of 1.15 to 1.96.

     Contribution Analysis

     CSFB analyzed the relative contributions of WABCO and MotivePower to the
estimated revenues, EBITDA, EBIT and net income of the pro forma combined
company for fiscal years 1999 and 2000. This analysis indicated that based on
the WABCO management case and the MotivePower management case and without
consideration of potential synergies, WABCO's and MotivePower's contributions
would be as set forth in the following table:



                                           WABCO    MPO
                                           -----    ---
                                           
1999 estimated        Revenues              63%     37%
1999 estimated        EBITDA                65%     35%
1999 estimated        EBIT                  66%     34%
1999 estimated        Net Income            60%     40%
2000 estimated        Revenues              65%     35%
2000 estimated        EBITDA                66%     34%
2000 estimated        EBIT                  67%     33%
2000 estimated        Net Income            63%     37%


     In summary, CSFB's analysis resulted in an implied exchange ratio range of
1.30 to 1.80.

     Historical Exchange Ratio Analysis

     CSFB compared the historical stock prices of WABCO and MotivePower over
various periods and derived the implied exchange ratios from those prices. Based
on the average exchange ratios over periods ranging from 30 days to two years,
ending on May 25, 1999, the implied exchange ratio range was 1.12 to 1.37.

     Pro Forma Transaction Analysis

     CSFB analyzed the potential pro forma effect of the merger on earnings per
share with respect to the shareholders of WABCO for the fiscal years 1999
through 2001, using the WABCO management case and the MotivePower management
case, assuming qualification of the merger for pooling of interests accounting
treatment and the achievement of the per-year synergy levels estimated by WABCO
and MotivePower managements. This analysis suggested that, with respect to
WABCO's shareholders, the merger would be dilutive to earnings per share in
fiscal years 1999 and 2000 and accretive to earnings per share in fiscal year
2001. The actual results that the combined company achieves may, however, vary
from projected results and these variations may be material.

     Miscellaneous

     Pursuant to the terms of CSFB's engagement, WABCO has agreed to pay CSFB a
fee of $4,700,000, $150,000 of which was payable upon CSFB's engagement and the
remainder of which will be payable upon consummation of the merger. WABCO will
also reimburse CSFB for certain out-of-pocket expenses incurred by CSFB in
connection with its services to WABCO, including fees and expenses of legal
counsel. WABCO has agreed to indemnify CSFB, its affiliates, the respective
directors, officers, partners, agents and employees of CSFB and its affiliates,
and each person, if any, controlling CSFB or any of its affiliates, against
certain liabilities, including liabilities under the federal securities laws.

     CSFB has in the past performed certain investment banking services for
WABCO, for which CSFB has received customary fees. In the ordinary course of its
business, CSFB and its affiliates may actively trade the debt and equity
securities of WABCO and MotivePower for their own accounts and for the accounts
of customers and, accordingly, may at any time hold a long or short position in
such securities. As of June 2, 1999, CSFB owned approximately 581,300 shares of
MotivePower common stock.

                   INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendation of the WABCO Board and the MotivePower
Board with respect to the merger agreement and the merger, shareholders should
be aware that certain members of the WABCO Board and the MotivePower Board and
certain members of the management of WABCO and MotivePower have interests in the
merger that may be different from, or in addition to, the interests of the other
shareholders of WABCO and MotivePower generally.

BOARD OF DIRECTORS

     MotivePower has agreed that, as of the closing, it will cause James C.
Huntington, Jr., James V. Napier, Kim G. Davis, William E. Kassling, Gregory T.
H. Davies, Emilio A. Fernandez and James P. Kelley, to be elected to the
MotivePower Board, each of whom were directors of WABCO prior to the merger. In
addition, at the closing Michael A. Wolf, chief executive officer of
MotivePower, will resign from the MotivePower Board and Robert S. Miller will
fill the vacancy created by Mr. Wolf's resignation. See "The Merger
Agreement -- MotivePower Board and Related Matters" on page I-64.

ADVISORY AGREEMENTS

     In connection with the merger, WABCO entered into agreements with Vestar
Capital Partners and Charlesbank Capital Partners, LLC providing for the payment
by WABCO to Vestar of a fee of $1,400,000 and to Charlesbank of a fee of
$250,000 for their respective assistance in the evaluation, negotiation and
                                      I-57
   64

consummation of the merger. Both agreements were approved by a disinterested
majority of the WABCO Board. Vestar Capital Partners is affiliated with Vestar
Equity Partners, L.P. which owned 2,400,000 shares of WABCO common stock, or
7.08% of the outstanding WABCO common stock, and Vestar Capital Partners, Inc.
which owned 40,000 shares of WABCO common stock, in each case, as of March 31,
1999. Mr. James P. Kelley is affiliated with Vestar Capital Partners and Vestar
Equity Partners, L.P. and serves as a director of WABCO and will serve as a
director of MotivePower following the merger. Charlesbank Capital Partners, LLC
acts as the investment advisor to Harvard Private Capital Holdings, which owned
2,401,000 shares of WABCO common stock, or 7.08% of the outstanding WABCO common
stock, as of March 31, 1999. Mr. Kim G. Davis is a Managing Director and
Co-founder of Charlesbank and serves as a director of WABCO and will serve as a
director of MotivePower following the merger.

INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE

     MotivePower has agreed to indemnify, to the extent provided under WABCO's
charter and by-laws in effect on June 2, 1999, the individuals who on or before
the closing were officers or directors of WABCO or its subsidiaries with respect
to all acts or omissions before the closing by these individuals in these
capacities. MotivePower has also agreed to provide, for six years after the
closing, a directors' and officers' liability insurance and indemnification
policy that provides WABCO's officers and directors in office immediately prior
to the closing coverage substantially equivalent to WABCO's policy in effect on
June 2, 1999. See "The Merger Agreement -- Covenants -- Indemnification and
Insurance of WABCO Directors and Officers" on page I-68.

STOCK OPTIONS

     WABCO Stock Options. At the effective time, each outstanding option granted
by WABCO to purchase shares of WABCO common stock will be assumed by MotivePower
and will, after the effective time, constitute an option to acquire, on the same
terms and subject to the same conditions as applied to the WABCO stock option
prior to the effective time, the number, rounded down to the nearest whole
number, of shares of MotivePower common stock determined by multiplying:

     - the number of shares of WABCO common stock subject to the option
       immediately before the effective time by

     - the exchange ratio.

     The exercise price of each of these options will be a price per share of
MotivePower common stock, rounded up to the nearest cent, equal to:

     - the per share exercise price for WABCO common stock that otherwise could
       have been purchased under the WABCO stock option divided by

     - the exchange ratio.

     Except as described above with regard to the conversion of WABCO options
into options to purchase MotivePower common stock, the merger will not
materially affect options granted to WABCO employees, including WABCO executive
officers, or non-employee directors of WABCO. The WABCO 1995 Stock Incentive
Plan and the WABCO 1995 Non-Employee Directors' Fee and Stock Option Plan will
continue to govern those outstanding options. Options granted to these
individuals that are not exercisable prior to the effective time of the merger
will become exercisable at the same times, on the same terms and subject to the
same conditions as applied to the options prior to the effective time of the
merger.

     WABCO also has performance-based options outstanding to some management
employees. The performance targets are based upon fully-diluted earnings per
share of WABCO. It is our present intention to continue to measure the vesting
of these performance options by the earnings per share of the WABCO businesses
as calculated prior to the merger. These arrangements will be administered in
accordance with the past practices and interpretations of the WABCO Board and
Compensation Committee. Any question regarding the past practices and
interpretations of the WABCO Board and the WABCO Compensation

                                      I-58
   65

Committee and the application of these past practices and interpretations to the
facts and circumstances in a given case after the merger will be referred to the
Compensation Committee of the combined company for a final decision. This
decision may not be inconsistent with the intention of the merger agreement and
the merger.

     Other WABCO Stock Plans. The WABCO 1998 Employee Stock Purchase Plan was
terminated effective immediately following the purchase period under that plan
ending June 30, 1999. There will be no additional purchase periods in which
WABCO employees may participate and purchase shares of WABCO stock through the
use of payroll deductions.

     We anticipate that the WABCO 1997 Executive Retirement Plan will continue
in effect for eligible employees and shares of MotivePower common stock will be
substituted under the plan for shares of WABCO common stock at the effective
time of the merger.

     MotivePower Stock Options, Restricted Stock and Stock Appreciation
Rights. Each outstanding option granted by MotivePower to purchase shares of
MotivePower common stock will, after the effective time, continue to be an
option to purchase the same number of shares of MotivePower common stock at the
same exercise price per share.

     The merger will have no effect upon options granted to nonemployee
directors of MotivePower. Thus, options granted to these nonemployee directors
that are not exercisable prior to the effective time will become exercisable at
the same times, on the same terms and subject to the same conditions as applied
to the options prior to the effective time.

     The merger will affect the stock options, shares of restricted stock and
stock appreciation rights granted to MotivePower employees, including
MotivePower executive officers, as follows:

     - Options granted to MotivePower employees, including MotivePower executive
       officers, that are not exercisable prior to the effective time will
       become exercisable if and at the time that the MotivePower shareholders
       approve the merger agreement.

     - Restrictions on shares of restricted stock granted by MotivePower to
       Messrs. Pope and Wolf that will not have lapsed prior to the effective
       time will lapse if and at the time that the MotivePower shareholders
       approve the merger agreement. The numbers of shares of restricted stock
       held by Messrs. Pope and Wolf with respect to which restrictions will
       lapse as a result of the merger are 37,500 and 75,000 respectively.

     - Stock appreciation rights granted to Mr. Wolf that are not exercisable
       prior to the effective time will become exercisable for shares of
       MotivePower common stock immediately prior to the effective time. The
       aggregate market value of the shares of MotivePower common stock issuable
       upon the exercise of these stock appreciation rights is $303,750.

     The following table shows the options to purchase shares of MotivePower
common stock that will become exercisable as a result of the merger held by each
of the executive officers of MotivePower, assuming the merger is effective
August 31, 1999. All references in the table and elsewhere in this joint proxy
statement/prospectus to shares that may be purchased upon the exercise of
MotivePower stock options and their exercise price per share and to shares of
restricted stock and stock appreciation rights granted by

EMPLOYMENT AGREEMENTS

     John C. Pope. John C. Pope serves as Chairman of the Board of MotivePower
pursuant to the terms of an employment agreement between Mr. Pope and
MotivePower. Under the agreement, Mr. Pope is entitled to a base salary of
$350,000 per year, which may be increased from time to time and which currently
is $372,000. The agreement also provides for secretarial assistance for Mr. Pope
for a maximum of 25 hours per week, the provision of office equipment not to
exceed $10,000 and medical and dental benefits. Mr. Pope is required to devote
not more than an average of three days per week to the business and affairs of
MotivePower. The agreement further provides for the grant of 450,000 stock
appreciation rights. A maximum value was fixed for these rights at $4.60 per
right in connection with the grant to Mr. Pope of options to purchase 450,000
shares of MotivePower common stock. These rights were exercised and the
resulting amount was deferred into the MotivePower common stock account under
MotivePower's Deferred Compensation Plan. In addition, the agreement provides
for the grant of 75,000 shares of restricted stock. The restrictions on one-half
of these shares of restricted stock have lapsed and the restrictions on the
remaining shares of restricted stock will lapse pursuant to MotivePower's Stock
Incentive Plan if and at the time that the MotivePower shareholders approve the
merger agreement. If the merger agreement is not approved, these restrictions
will lapse upon the earliest of (1) January 1, 2007 so long as Mr. Pope is
employed by MotivePower on that date, (2) the occurrence of a change in control
of MotivePower, (3) Mr. Pope's

                                      I-60
   67

termination of employment due to death or disability or (4) Mr. Pope's
termination of employment by MotivePower other than for cause.

     The initial term of Mr. Pope's employment agreement was two years and is
subject to annual automatic one-year extensions, unless notice of the automatic
extension provision is terminated by MotivePower. Currently, the term of the
agreement ends on January 2, 2000. If Mr. Pope terminates his employment at any
time within a period of two years, which period was 90 days prior to an
amendment to the employment agreement dated as of May 27, 1999, following the
effective time of the merger, or if MotivePower terminates Mr. Pope's employment
following the effective time of the merger, Mr. Pope will be entitled, in lieu
of any further salary and bonus payments, to the following payments and
benefits:

     - a lump sum payment equal to two times the sum of the following amounts:
       the amount of Mr. Pope's annual base salary, at the rate in effect
       immediately preceding his termination of employment or the rate in effect
       immediately preceding the effective time of the merger, whichever is
       greater, and the amount of Mr. Pope's annual bonus received for the year
       prior to his termination of employment or the year prior to the effective
       time of the merger, or the amount of Mr. Pope's target bonus for either
       of those years, whichever is greatest;

     - for a period of two years after Mr. Pope's employment is terminated,
       health insurance substantially similar to that provided to Mr. Pope
       during his employment, secretarial assistance for a maximum of 25 hours
       per week and reimbursement for reasonable computer support, telephone,
       postage and other out-of-pocket expenses incurred by Mr. Pope in
       connection with the operation of his office;

     - the restrictions on all shares of restricted stock shall lapse and all
       stock options shall become exercisable, as described above; and

     - if any payment or benefit received or to be received by Mr. Pope in
       connection with the merger or the termination of his employment is
       subject to the excise tax imposed under Section 4999 of the Internal
       Revenue Code, MotivePower will reimburse Mr. Pope in an amount such that
       Mr. Pope receives actual payments or benefits in an amount not less than
       that which he would have received if no obligation for the excise tax, or
       any additional tax on tax reimbursements received including income tax,
       had arisen.

     Michael A. Wolf. Michael A. Wolf serves as President and Chief Executive
Officer of MotivePower pursuant to the terms of an employment agreement between
Mr. Wolf and MotivePower. Under the agreement, Mr. Wolf is entitled to a base
salary of $475,000 per year, which amount was $398,000 prior to an amendment to
the employment agreement dated May 13, 1999, and a bonus under MotivePower's
Executive Incentive Plan. The agreement also provides for participation in a
deferred compensation plan and participation in all perquisites and health and
welfare benefits consistent with MotivePower's policies for other executive
personnel. In addition, the agreement provides for a term life insurance policy
on the life of Mr. Wolf having a death benefit of up to $1,000,000.

     In addition, MotivePower granted to Mr. Wolf 150,000 shares of restricted
stock pursuant to the agreement. The restrictions on 75,000 of these shares
lapsed on June 30, 1999. The restrictions on the remaining 75,000 shares will
lapse pursuant to MotivePower's Stock Incentive Plan if and at the time that the
MotivePower shareholders approve the merger agreement. If the merger agreement
is not approved, these restrictions will lapse upon the earliest of (1) June 30,
2000 so long as Mr. Wolf is employed by MotivePower on that date, (2) the
occurrence of a change in control of MotivePower, (3) Mr. Wolf's termination of
employment due to death or disability or (4) Mr. Wolf's termination of
employment by MotivePower other than for cause. Also pursuant to the agreement,
MotivePower granted to Mr. Wolf 600,000 stock appreciation rights. A maximum
value was fixed for these rights at $1.69 per right in connection with the grant
to Mr. Wolf of options to purchase 600,000 shares of MotivePower common stock.
As of the date of this Joint Proxy Statement/Prospectus 420,000 of the rights
have been exercised and the resulting amounts were deferred into the MotivePower
common stock account under MotivePower's Deferred Compensation Plan, and 180,000
of the rights become exercisable for shares of MotivePower common stock
immediately prior to the effective time if the merger is consummated. If the
merger is not consummated,

                                      I-61
   68

these rights become exercisable for shares of MotivePower common stock on July
1, 2000, provided that Mr. Wolf has not voluntarily terminated his employment
before then, or if earlier, immediately prior to a change in control of
MotivePower, upon Mr. Wolf's termination of employment due to death or
disability or Mr. Wolf's termination of employment by MotivePower other than for
cause.

     The initial term of Mr. Wolf's employment agreement was 24 months and is
subject to monthly automatic one-month extensions through June 30, 1999, so that
there remains a 24-month term at all times through June 30, 1999. Thereafter,
the term of the agreement expires on July 1, 2001. If Mr. Wolf terminates his
employment at any time within a period of 90 days following the effective time
of the merger, or if MotivePower terminates Mr. Wolf's employment following the
effective time of the merger or in contemplation of or within 90 days prior to
the effective time of the merger, Mr. Wolf will be entitled, in lieu of any
further salary and bonus payments, to the following payments and benefits:

     - a lump sum payment equal to three times, two times prior to the amendment
       to the employment agreement dated May 13, 1999, the sum of the following
       amounts: the amount of Mr. Wolf's annual base salary, at the rate in
       effect immediately preceding his termination of employment or the rate in
       effect immediately preceding the effective time, whichever is greater,
       and the amount of Mr. Wolf's annual bonus received for the year prior to
       his termination of employment or the year prior to the effective time, or
       the amount of Mr. Wolf's maximum target bonus for either of those years,
       whichever is greatest;

     - for a period of 12 months after Mr. Wolf's employment is terminated or
       until Mr. Wolf finds new employment, whichever occurs first, perquisites,
       health and welfare benefits and life insurance similar to that provided
       to Mr. Wolf during his employment, which benefit was added by the
       amendment to the employment agreement dated May 13, 1999;

     - the restrictions on all shares of restricted stock shall lapse and all
       stock options and stock appreciation rights shall become exercisable, as
       described above; and

     - if any payment or benefit received or to be received by Mr. Wolf in
       connection with the merger or the termination of his employment is
       subject to the excise tax imposed under Section 4999 of the Internal
       Revenue Code, MotivePower will reimburse Mr. Wolf in an amount such that
       Mr. Wolf receives actual payments or benefits in an amount not less than
       that which he would have received if no obligation for the excise tax, or
       any additional tax on tax reimbursements received including income tax,
       had arisen.

     The agreement also generally restricts Mr. Wolf from competing with
MotivePower for two years following the termination of his employment.

EMPLOYMENT CONTINUITY AGREEMENTS

     MotivePower entered into Employment Continuity Agreements with 13 of its
executives and key employees, including Joseph S. Crawford, Jr., Executive Vice
President and Chief Operating Officer, William F. Fabrizio, Senior Vice
President and Chief Financial Officer, David L. Bonvenuto, Vice President,
Controller and Principal Accounting Officer, Jeannette Fisher-Garber, Vice
President, General Counsel and Secretary, Thomas P. Lyons, Vice President and
Treasurer, Jeffrey A. Plut, Vice President, Corporate Development, Scott E.
Wahlstrom, Vice President, Human Resources and Administration and Timothy R.
Wesley, Vice President, Investor and Public Relations, effective April 1, 1999.
In accordance with the intent of the MotivePower Board when adopting the
agreements, amendments to the agreements were approved by the MotivePower Board
on May 18, 1999 to confirm that the change in control covered by the agreements
included a transaction of the type contemplated by the merger. Pursuant to each
agreement, the employee agrees to continue the employee's employment by
MotivePower for the period which began on June 3, 1999 and will continue until
the effective time of the merger or until the merger is abandoned. Each
agreement provides that MotivePower will pay a retention bonus to the employee
promptly following the end of that period if the employee remains employed by
MotivePower until the end of the period or MotivePower terminates the employee's
employment before the end of the period other than for good cause, as defined in

                                      I-62
   69

the agreement. The retention bonus is in the form of a lump sum cash amount
equal to six months of the employee's monthly base salary in effect on June 3,
1999 and is in addition to all other compensation to which the employee may be
entitled.

     In addition, each agreement provides that if within 24 months after the
effective time of the merger MotivePower terminates the employee's employment
other than for good cause or the employee voluntarily terminates employment for
good reason, as defined in the agreement, the employee will be entitled to the
following payments and benefits, in addition to all other compensation to which
the employee may be entitled:

     - within 30 days following termination, a lump sum cash amount equal to 18
       months of the employee's monthly base salary in effect upon the date of
       termination in the case of William F. Fabrizio, Jeannette Fisher-Garber
       and Joseph S. Crawford, 15 months of the employee's monthly base salary
       in effect upon the date of termination in the case of seven employees,
       including Timothy R. Wesley and Scott E. Wahlstrom, and 12 months of the
       employee's monthly base salary in effect upon the date of termination in
       the case of Jeffrey A. Plut, Thomas P. Lyons and David L. Bonvenuto;

     - for the number of months following termination that is equal to the
       number of months of base salary payable to the employee, the continuation
       of the participation of the employee and the employee's dependents in
       MotivePower's health, life, disability and other employee welfare benefit
       plans, programs and arrangements or the provision of substantially
       similar benefits; and

     - if any payment or benefit received or to be received by the employee in
       connection with the merger or the termination of the employee's
       employment is subject to the excise tax imposed under Section 4999 of the
       Internal Revenue Code, MotivePower will reimburse the employee in an
       amount such that the employee receives actual payments or benefits in an
       amount not less than that which the employee would have received if no
       obligation for the excise tax, or any additional tax on tax
       reimbursements received including income tax, had arisen.

     Each agreement also generally restricts the employee from competing with
MotivePower for the number of months following the termination of the employee's
employment that is equal to the number of months of base salary payable to the
employee.

EXECUTIVE INCENTIVE PLAN

     MotivePower's Executive Incentive Plan provides annual cash awards to 45
key senior management employees, including all of the executive officers. Awards
are based on specific and measurable employee performance, as well as on the
performance and contribution to MotivePower's overall results of the business
unit, division or subsidiary of MotivePower for which the employee performs
services. Pursuant to an amendment to the plan adopted on June 2, 1999, the plan
was clarified to provide that if an employee's employment is terminated by
MotivePower without cause or by the employee for good reason following a change
in control of MotivePower during the award year of the change in control, or the
subsequent year and prior to making of awards for that award year, the employee
would be deemed to have remained employed at the time awards are made for the
award year of the change in control and be deemed to have achieved all
individual goals for that year. The amendment also added clarifying language
specifying that the award for the award year in which a change in control of
MotivePower occurs would be calculated based on the results of operations of
MotivePower's business units, divisions and subsidiaries without giving effect
to the transaction that gives rise to the change in control. In addition, the
amendment deleted language which prohibited the amendment or termination of the
plan following a change in control until the beginning of the third fiscal year
following the fiscal year of the change in control and replaced that language
with the requirement that any such amendment or termination not adversely affect
the award fund for the award year of the change in control, or the preceding
year if the awards for that year have not been paid, or any employee's rights
with respect thereto. The amendment is applicable to change in control
transactions of the type contemplated by the merger.

                              THE MERGER AGREEMENT

     The following summary of the merger agreement is qualified by reference to
the complete text of the merger agreement, which is incorporated by reference
and attached as Annex A.

STRUCTURE OF THE MERGER

     Under the merger agreement, WABCO will merge into MotivePower.

TIMING OF CLOSING

     The closing will occur no later than two business days after the day on
which the last of the conditions set forth in the merger agreement has been
satisfied or waived, unless MotivePower and WABCO agree to a different date. We
expect that, immediately upon the closing of the merger, we will file a
certificate of merger with the Secretary of State of the State of Delaware and
file articles of merger with the Department of State of the Commonwealth of
Pennsylvania, at which time the merger will be effective.

MERGER CONSIDERATION

     The merger agreement provides that each share of WABCO common stock
outstanding immediately prior to the effective time will, at the effective time,
be converted into the right to receive 1.3 shares of MotivePower common stock.
However, any shares of WABCO common stock held by WABCO as treasury stock or by
any wholly-owned subsidiary of WABCO or owned by MotivePower or any wholly-owned
subsidiary of MotivePower will be canceled without any payment for those shares.

TREATMENT OF WABCO STOCK OPTIONS

     At the effective time, each outstanding option granted by WABCO to purchase
shares of WABCO common stock will be converted into an option to acquire
MotivePower common stock having the same terms and conditions as the WABCO stock
option had before the effective time. The number of shares that the new
MotivePower option will be exercisable for and the exercise price of the new
MotivePower option will reflect the exchange ratio in the merger. See "Interests
of Certain Persons in the Merger -- Stock Options" on page I-57.

EXCHANGE OF SHARES

     We will appoint an exchange agent to handle the exchange of WABCO common
stock certificates in the merger for MotivePower common stock and the payment of
cash for fractional shares of WABCO common stock. Soon after the closing, the
exchange agent will send to each holder of WABCO stock a letter of transmittal
for use in the exchange and instructions explaining how to surrender WABCO
common stock certificates to the exchange agent. Holders of WABCO common stock
that surrender their certificates to the exchange agent, together with a
properly completed letter of transmittal, will receive the appropriate merger
consideration. Holders of unexchanged shares of WABCO common stock will not be
entitled to receive any dividends or other distributions payable by MotivePower
after the closing until their certificates are surrendered.

     MotivePower will not issue any fractional shares in the merger. Holders of
WABCO common stock will receive cash for any fractional shares of MotivePower
common stock owed to them in an amount based on the market value of MotivePower
common stock on the date on which the merger occurs.

MOTIVEPOWER BOARD AND RELATED MATTERS

     The merger agreement provides that as of the effective time:

     - The MotivePower Board size will be increased from 7 to 14.

     - Two employee directors of WABCO will become directors of MotivePower.
       They are William E. Kassling and Gregory T.H. Davies.

       MotivePower. They are Kim G. Davis, Emilio A. Fernandez, James C.
       Huntington, Jr., James V. Napier and James P. Kelley.

     - Michael A. Wolf will resign from the MotivePower Board at the closing and
       Robert S. Miller will fill the vacancy created by Mr. Wolf's resignation.
       Mr. Miller has served as a director of Waste Management Inc. since May
       1997. He served as Chairman of the Board of Waste Management from October
       1997 until May 1999. He served as Acting Chief Executive Officer from
       October 1997 until March 1998. On March 10, 1998, Mr. Miller was named
       Chief Executive Officer of Waste Management. Mr. Miller is serving as
       Vice Chairman of Morrison Knudsen Corporation, an engineering and
       construction firm. He also served as Chief Executive Officer of
       Federal-Mogul Corporation, an automotive parts manufacturing firm, from

       Corporation from April 1995 until September 1996. He was a member of the
       Board of Directors of MotivePower from April 1995 until September 1996.
       In addition, since 1993 he has served as Vice President and Treasurer of
       Moore Mill and Lumber, a privately-held forest products firm, and from
       1992 to 1993, he served as Senior Partner of James D. Wolfensohn, Inc.,
       an investment banking firm. From 1979 to 1992, Mr. Miller worked at
       Chrysler Corporation, an automobile and truck manufacturing firm, rising
       to become Vice Chairman of the Board after serving as Chrysler's Chief
       Financial Officer. Mr. Miller is a director of Federal-Mogul Corporation,

     - Mr. Pope will remain Chairman of the MotivePower Board.

     - Ernesto Fernandez-Hurtado has indicated his intention to step down as a
       director of MotivePower prior to the completion of his term. The Board of
       the combined company intends to appoint a Mexican national to fill this
       vacancy in light of the significant amount of business the combined
       company will have in Mexico.

     - The MotivePower Board will have the following Committees:

          - Executive Committee -- comprised of Messrs. Kassling (Chairman),
            Kelley and Pope.

            determinations relating to (1) compensation of the Chief Executive
            Officer or its other four highest compensated employees, to the
            extent such compensation could exceed $1,000,000, in any one year
            for any such employee and MotivePower intends the compensation to
            qualify for the performance-based exception to the limitation on
            deductibility of compensation in excess of $1,000,000 as provided in
            Section 162(m) of the Internal Revenue Code, or (2) compensation for
            persons subject to Section 16 of the Securities Exchange Act of
            1934, should such matters be presented to the Compensation
            Committee.

          - Operations Committee -- comprised of Messrs. Kassling (Chairman),
            Davies, Davis, Pope and Foster.

its Committees, in "Summary of Functions and Powers of the MotivePower and WABCO
Board Committees" on page II-11.

     No Solicitation. Each of WABCO and MotivePower has agreed that it and its
subsidiaries and their respective officers, directors, employees and advisers,
as the case may be, will not (1) solicit, initiate or knowingly encourage an
offer for an alternative acquisition transaction involving WABCO or MotivePower,
as the case may be, of a nature defined in the merger agreement, (2) enter into
any agreement with respect to any alternative transaction, or (3) participate in
any discussions or negotiations regarding, or furnish any person any information
with respect to, or take any other action to facilitate any inquiries or the
making of any proposal that constitutes, or may reasonably be expected to lead

actions are permitted in response to an unsolicited bona fide offer so long as
prior to doing so: (1) a majority of the members of the WABCO Board or
MotivePower Board, as the case may be, in good faith determines, after
consultation with outside legal counsel, that it is necessary to do so to comply

case may be, and (2) WABCO or MotivePower, as the case may be, receives an
executed confidentiality agreement from this offeror with terms no less
favorable to WABCO or MotivePower, as the case may be, than those contained in
the existing confidentiality agreement between MotivePower and WABCO.

     WABCO and MotivePower must keep the other party informed of the identity of
any potential bidder and the terms and status of any offer.

     WABCO Board's Covenant to Recommend. The WABCO Board has agreed to
recommend the approval and adoption of the merger agreement and the merger to

     Interim Operations of MotivePower and WABCO. Each of MotivePower and WABCO
has undertaken a separate covenant that places restrictions on it and its
subsidiaries until either the effective time or the merger agreement is
terminated. In general, MotivePower and its subsidiaries and WABCO and its

consistent with past practice and to use their reasonable best efforts to
preserve intact their business organizations, relationships with third parties
and to keep available the services of their present officers and employees. The

necessary or advisable under applicable laws to complete the merger and the
other transactions contemplated by the merger agreement as promptly as
practicable, (2) obtain from any governmental entity any consents, approvals or
authorizations required to be obtained or made by MotivePower and WABCO in
connection with the execution of the merger agreement and the transactions
contemplated by the merger agreement and (3) make all necessary filings and all
other submissions required under the securities laws of the United States and
any other applicable law. In connection with seeking any approval of a
governmental entity, neither MotivePower nor WABCO shall be required to commit
to any divestiture transaction, agree to sell or hold separate any of
MotivePower's or WABCO's businesses, or agree to any changes or restrictions in
the operation of those businesses, if the divestiture or these restrictions
would be reasonably expected to have a material adverse effect on MotivePower,
WABCO and their subsidiaries, taken as a whole. However, MotivePower and WABCO
have each agreed to dispose of businesses with a fair market value of no more
than $25 million or revenues for the most recently completed 12 months of no
more than $25 million in order to settle or resolve some antitrust actions.

     Employee Benefits Matters. The merger agreement provides that MotivePower
will honor all MotivePower and WABCO employee benefit plans and employment
agreements.

     The merger agreement provides that all individuals who are employees of
WABCO or any of its subsidiaries at the effective time shall be given credit for
all service with WABCO and its subsidiaries under all employee benefit plans and
arrangements currently maintained by MotivePower in which they become
participants for purposes of eligibility, vesting and certain other matters to
the same extent as if rendered to MotivePower.

     Indemnification and Insurance of WABCO Directors and Officers. MotivePower
has agreed that:

     - It will indemnify WABCO directors and officers for liabilities from their
       acts or omissions in those capacities occurring prior to closing to the
       extent provided under WABCO's charter and by-laws as in effect on June 2,
       1999.

     - For six years after closing, it will provide to WABCO's directors and
       officers liability insurance protection substantially equivalent in kind
       and scope as the coverage provided by WABCO's current officers' and
       directors' liability insurance policies, except that, subject to
       limitations, MotivePower will not be obligated to pay in any one year an
       amount in excess of 150% of the annual premium paid by WABCO for this
       insurance on June 2, 1999.

     Other Covenants. The merger agreement contains mutual covenants of the
parties, the most significant of which are:

     - that each party agrees to take all actions reasonably necessary to obtain
       a favorable determination (if required) from the SEC that the merger may
       be accounted for as a pooling of interests; and

     - that WABCO agrees to have the stockholders agreement and voting trust to
       which it is a party terminated prior to the closing.

      of accountant's letters regarding accounting treatment of the merger.

     In addition, WABCO represents and warrants to MotivePower as to certain
other matters, including the inapplicability of the Delaware anti-takeover
statute to the merger, the merger agreement and the WABCO stock option
agreement. In addition, MotivePower represents and warrants to WABCO as to some
other matters, including the inapplicability of provisions of MotivePower's
articles of incorporation and MotivePower's shareholder rights plan to the
merger, the merger agreement and the MotivePower stock option agreement. For
information about the anti-takeover statute and the rights plan, see "Legal
Information -- Comparison of Shareholder Rights -- Shareholder Rights Plan" on
page II-7.

     The representations and warranties in the merger agreement do not survive
the closing or termination of the merger agreement.

prior to the closing in any of the following ways:

     (a) The merger agreement may be terminated by mutual written consent of
MotivePower and WABCO.

     (b) The merger agreement may be terminated by either MotivePower or WABCO
if:

          (1) the merger has not been completed by November 30, 1999,

          (2) there is a permanent legal prohibition to closing the merger,

          (3) MotivePower or WABCO shareholders fail to adopt and approve the

          (4) - on or prior to July 17, 1999, the MotivePower Board has
                determined to recommend an acquisition proposal to its
                shareholders and to enter into an agreement concerning the
                acquisition proposal after determining, subject to complying
                with the merger agreement, that the acquisition proposal is more
                favorable to MotivePower shareholders than the merger, and
                MotivePower has delivered to WABCO a written notice of
                MotivePower's intent to enter into an agreement, attaching the
                most current version of the agreement to the notice,

              - five business days have elapsed following delivery to WABCO of

                intent of enabling WABCO to agree to a modification of the terms
                of the merger agreement so that the transactions contemplated by
                the merger agreement may be effected,

              - at the end of the five business day-period the MotivePower Board
                continues reasonably to believe that the acquisition proposal is
                more favorable to MotivePower shareholders than the merger, and

              - MotivePower has paid WABCO the cash termination fee described
                under "-- Termination Fees Payable by MotivePower" on page I-71,
                or

          (5) - on or prior to July 17, 1999, the WABCO Board has determined to
                recommend an acquisition proposal to its shareholders and to
                enter into an agreement concerning the acquisition proposal
                after determining, subject to complying with the merger
                agreement, that the acquisition proposal is more favorable to
                WABCO shareholders than the merger, and

                                      I-69
   76

            WABCO has delivered to MotivePower written notice of WABCO's intent
            to enter into an agreement, attaching the most current version of
            the agreement to the notice,

              - five business days have elapsed following delivery to
                MotivePower of the written notice by WABCO and during the five
                business day-period WABCO has fully cooperated with MotivePower
                with the intent of enabling MotivePower to agree to a
                modification of the terms of the merger agreement so that the
                transactions contemplated by the merger agreement may be
                effected,

              - at the end of the five business day-period the WABCO Board
                continues reasonably to believe that the acquisition proposal is
                more favorable to WABCO shareholders than the merger, and

              - WABCO has paid MotivePower the cash termination fee described
                under "-- Termination Fees Payable by WABCO" below.

     (c) The merger agreement may be terminated by WABCO if:

          (1) the MotivePower Board has not recommended or has modified in a
              manner materially adverse to WABCO its recommendation of the
              merger agreement and the merger,

          (2) MotivePower shall have materially and knowingly breached the
              covenants described under " -- Covenants -- No Solicitation" on
              page I-65 or " -- Covenants -- MotivePower Board's Covenant to
              Recommend" on page I-66, or

          (3) if a material breach of or failure to perform any representation,
              warranty or covenant on the part of MotivePower set forth in the
              merger agreement has occurred which would cause some of the
              conditions under " -- Conditions to the Completion of the Merger"
              on page I-68 not to be satisfied, and these conditions are
              incapable of being satisfied by November 30, 1999.

     (d) The merger agreement may be terminated by MotivePower if:

          (1) the WABCO Board has not recommended or has modified in a manner
              materially adverse to MotivePower its recommendation of the merger
              agreement and the merger,

          (2) WABCO has materially and knowingly breached the covenants
              described under " -- Covenants -- No Solicitation" on page I-65 or
              " -- Covenants -- WABCO Board's Covenant to Recommend" on page
              I-66, or

          (3) if a material breach of or failure to perform any representation,
              warranty or covenant on the part of WABCO set forth in the merger
              agreement has occurred which would cause some of the conditions
              under " -- Conditions to the Completion of the Merger" on page
              I-68 not to be satisfied, and these conditions are incapable of
              being satisfied by November 30, 1999.

     Neither MotivePower nor WABCO can terminate the merger agreement for the
reasons described in paragraph (b)(1) above if its failure to fulfill its
obligations under the merger agreement has resulted in the failure to complete
the merger on or before November 30, 1999.

     If the merger agreement is validly terminated, there will be no liability
or obligation on the part of MotivePower, WABCO or their respective officers,
directors, shareholders or affiliates unless this party is in willful breach
thereof. However, the provisions of the merger agreement relating to expenses
and termination fees, as well as the confidentiality agreement and the
MotivePower and WABCO stock option agreements entered into between MotivePower
and WABCO, will continue in effect notwithstanding termination of the merger
agreement.

     Termination Fees Payable by WABCO. WABCO has agreed to pay MotivePower a
cash amount equal to $15 million plus reimburse MotivePower for up to $2 million
of its out-of-pocket fees and expenses incurred

                                      I-70
   77

in connection with the merger agreement and the transactions contemplated by the
merger agreement in any of the following circumstances:

     - the merger agreement is terminated as described in paragraph (b)(5),
       (d)(1) or (d)(2) under " -- Right to Terminate" above

     - the merger agreement terminates in circumstances where the following two
       conditions are met:

          - WABCO's shareholders fail to adopt and approve the merger agreement
            and the merger at a duly held meeting, and

          - either (1) a third party has made a proposal for an alternative
            transaction after June 2, 1999 and prior to the WABCO shareholders
            meeting or (2) the WABCO Board has not recommended or has modified
            in a manner materially adverse to MotivePower its recommendation of
            the merger agreement and the merger.

     Termination Fees Payable by MotivePower. MotivePower has agreed to pay
WABCO a cash amount equal to $15 million plus reimburse WABCO for up to $2
million of its out-of-pocket fees and expenses incurred in connection with the
merger agreement and the transactions contemplated by the merger agreement in
any of the following circumstances:

     - the merger agreement is terminated as described in paragraph (b)(4),
       (c)(1) or (c)(2) under " -- Right to Terminate" on page I-69

     - the merger agreement terminates in circumstances where the following two
       conditions are met:

          - MotivePower's shareholders fail to adopt and approve the merger
            agreement and the merger at a duly held meeting, and

          - either (1) a third party has made a proposal for an alternative
            transaction after June 2, 1999 and prior to the MotivePower
            shareholders meeting or (2) the MotivePower Board has not
            recommended or has modified in a manner materially adverse to WABCO
            its recommendation of the merger agreement and the merger.

EXPENSES

     Except as described above and subject to an exception relating to the
payment of transfer taxes, all costs and expenses incurred in connection with
the merger agreement and related transactions will be paid by the party
incurring these costs or expenses. However, MotivePower and WABCO will share
equally all fees and expenses, other than attorneys' and accounting fees and
expenses, incurred in relation to the printing and filing of this joint proxy
statement/prospectus. We estimate that merger-related fees and expenses,
consisting primarily of SEC filing fees, fees and expenses of investment
bankers, attorneys and accountants, and financial printing and other related
charges, will total approximately $20-25 million assuming the merger is
completed.

AMENDMENTS

     Any provision of the merger agreement may be amended prior to closing if
the amendment is in writing and signed by WABCO and MotivePower and authorized
by our boards of directors. After the approval and adoption of the merger
agreement and the merger by the shareholders of WABCO or MotivePower, no
amendment that by law requires further approval by shareholders may be made
without the further approval of the shareholders.

STOCK OPTION AGREEMENTS

     The following summary of the WABCO stock option agreement and the
MotivePower stock option agreement is qualified by reference to the complete
text of the agreements, which are incorporated by reference and attached as
Annex B and Annex C.

                                      I-71
   78

     General. At the same time that MotivePower and WABCO entered into the
merger agreement, they also entered into the WABCO stock option agreement and
the MotivePower stock option agreement. Under the WABCO stock option agreement,
WABCO granted MotivePower an irrevocable option to purchase up to 6,453,710
shares of WABCO common stock at a price per share of $21.6125. Under the
MotivePower stock option agreement, MotivePower granted WABCO an irrevocable
option to purchase up to 5,133,655 shares of MotivePower common stock at a price
per share of $16.625. The options are exercisable in the circumstances described
below.

     Exercise of the Stock Options. MotivePower can exercise the WABCO option in
whole or in part at any time after the occurrence of any event entitling
MotivePower to receive the cash termination fee payable by WABCO pursuant to the
merger agreement (see " -- Termination of the Merger Agreement -- Termination
Fees Payable by WABCO" on page I-70) and prior to termination of the option.
WABCO can exercise the MotivePower option in whole or in part at any time after
the occurrence of any event entitling WABCO to receive the cash termination fee
payable by MotivePower pursuant to the merger agreement (see "-- Termination of
the Merger Agreement -- Termination Fees Payable by MotivePower" on page I-71)
and prior to termination of the option.

     The options terminate upon the earliest to occur of

          - the effective time of the merger,

          - subject to some limitations, 12 months after first becoming
     exercisable, or

          - 30 days after termination of the merger agreement if the option is
     not exercisable.

     The exercise price and number of option shares are also subject to the
anti-dilution and other adjustments specified in the stock option agreements.

     Any purchase of option shares is subject to specified closing conditions,
including receipt of applicable regulatory approvals.

     Cash Election. Each of the WABCO and MotivePower stock option agreements
further provides that, so long as the option is exercisable, the grantee of the
option may, instead of exercising the option, elect to require the grantor of
the option to pay to the grantee in exchange for the cancellation of the
relevant portion of the option an amount in cash equal to the "spread", as
defined below, multiplied by the number of option shares as to which this cash
election is made.

     "Spread" means the excess, if any, over the exercise price of the higher of
(1) the highest price per share of WABCO common stock or MotivePower common
stock, as the case may be, paid or proposed to be paid by any third party
pursuant to an alternative acquisition proposal and (2) the closing price of the
WABCO common stock or the MotivePower common stock, as the case may be, on the
NYSE on the last trading day immediately preceding the date on which MotivePower
or WABCO, as the case may be, notifies the other party of this cash election.

     Repurchase of Option Shares. If by the date that is the first anniversary
of the date of a termination of the merger agreement, neither the grantee of the
option nor any other person has acquired more than fifty percent of the shares
of outstanding common stock of the grantor of the option, then the grantor of
the option has the right to purchase all of the option shares acquired upon
exercise of the option at the greater of (1) the purchase price for these option
shares or (2) the average of the last sales prices for these shares on the five
trading days ending five days prior to the date the grantor gives written notice
of the exercise of this repurchase right.

     Sale of Shares. At any time prior to the first anniversary of a termination
of the merger agreement, the grantee of the option will have the right to sell
to the grantor all of the shares acquired upon exercise of the option at the
greater of (1) the purchase price for these option shares or (2) the average of
the last sales prices for these shares on the five trading days ending five days
prior to the date the grantee gives written notice of its intention to exercise
its sale right.

                                      I-72
   79

     Listing and Registration Rights. Each of WABCO and MotivePower has agreed
to list the option shares on the NYSE and to grant customary rights to require
registration by the grantor of the option shares for sale by the grantee under
the securities laws.

     Limitation on Total Profit. The stock option agreement provides that,
notwithstanding any other provision of that agreement or the merger agreement,
the total profit, as defined below, that the grantee may derive will not exceed
$30 million in the aggregate. If a grantee's total profit otherwise would exceed
this amount, the grantee shall repay the excess to the grantor in cash so that
the grantee's actually realized total profit does not exceed $30 million.

     "Total profit" as used in the stock option agreements means the sum, before
taxes, of the following: (1) (x) the amount of the termination fee under the
merger agreement received by the grantee, not including out-of-pocket expenses
that the grantor pays to the grantee, and the aggregate amount that the grantee
receives from exercising its cash election right described under " -- Cash
Election" above, less (y) any amount that the grantee repays to the grantor;
plus (2)(x) the amount that the grantee receives from exercising the put or call
right described under " -- Repurchase of Option Shares" or " -- Sale of Shares"
above, less (y) the grantee's purchase price for these shares; plus (3)(x) the
net cash amounts that the grantee receives from the sale of option shares (or of
any other securities into or for which such option shares are converted or
exchanged), less (y) the grantee's purchase price for these option shares.

     The stock option agreements also provide that the options may not be
exercised for a number of option shares that would, as of the date of exercise,
result in a notional total profit, as described below, exceeding $15 million. As
used in the stock option agreements, the "notional total profit" with respect to
the option shares for which the grantee of the option may propose to exercise
the option means the total profit determined as of the date the grantee notifies
the grantor of its intent to exercise the option and assuming that the
applicable option shares, together with all other option shares previously
acquired upon exercise of the option and held by the grantee or its affiliates
as of that date, were sold for cash at the closing market price on the preceding
trading day, less customary brokerage commissions.

     Effect of Options. The options are intended to make it more likely that the
merger will be completed on the agreed terms and to compensate WABCO or
MotivePower, as the case may be, for its efforts and costs in case the merger is
not completed under circumstances generally involving a third party proposal for
a business combination with WABCO or MotivePower. Among other effects, the
option could prevent an alternative business combination with WABCO or
MotivePower from being accounted for as a "pooling of interests." The option may
therefore discourage proposals for alternative business combinations with WABCO
or MotivePower, even if a third party were prepared to offer shareholders of
WABCO or MotivePower consideration with a higher market value than the value of
the MotivePower stock to be exchanged for WABCO stock in the merger.

                               LEGAL INFORMATION

                        COMPARISON OF SHAREHOLDER RIGHTS

     The rights of WABCO shareholders under Delaware law, the WABCO charter and
the WABCO by-laws prior to the merger are similar to the rights they will have
following the merger as MotivePower shareholders under Pennsylvania law, the
MotivePower charter and the MotivePower by-laws, with the principal exceptions
summarized in the chart below. Copies of the WABCO charter, the WABCO by-laws,
the MotivePower charter and the MotivePower by-laws are incorporated by
reference and will be sent to holders of shares of WABCO common stock upon
request. See "Where You Can Find More Information" on page III-1. The merger
agreement provides that at the effective time, the MotivePower by-laws will be
amended and restated as described in Exhibit 1.4(a) of the merger agreement. The
primary amendments made to the MotivePower by-laws relate to the establishment
of Board Committees of the MotivePower Board. The functions and powers of the
MotivePower and WABCO Board Committees are summarized in the chart below. The
summaries contained in the following charts are not intended to be complete and
are qualified by reference to Delaware law, Pennsylvania law, the WABCO charter,
the WABCO by-laws, the MotivePower charter, the MotivePower by-laws and the
shareholders' agreement and the voting trust agreement referenced herein.

  their responsibilities terminates immediately after the conclusion of the 2002
  annual meeting of shareholders. Upon the termination, the by-law provision
  relating to the establishment of the MotivePower Board Committees reverts to
  the language effective prior to the merger which provides, generally, that
  there will be an Executive and Finance Committee which will have the authority
  to exercise the powers of the Board, subject to exceptions, and any other
  committees as shall be established by the entire Board.

                    DESCRIPTION OF MOTIVEPOWER CAPITAL STOCK

     The following summary of the current terms of the capital stock of
MotivePower and the terms of the capital stock of MotivePower to be in effect
after completion of the merger is not meant to be complete and is qualified by
reference to the MotivePower charter and MotivePower by-laws. The MotivePower
charter is incorporated by reference and a copy will be sent to holders of
shares of MotivePower common stock and WABCO common stock upon request. See
"Where You Can Find More Information" on page III-1. The MotivePower by-laws are
incorporated by reference and included as an exhibit to the merger agreement
attached as Annex A.

AUTHORIZED CAPITAL STOCK

     Prior to Completion of the Merger. Under the MotivePower charter,
MotivePower's authorized capital stock consists of 55,000,000 shares of
MotivePower common stock, par value $0.01 per share, and 10,000,000 shares of
preferred stock, par value $0.01 per share.

     Following Completion of the Merger. The merger agreement provides that at
the effective time, the MotivePower charter will be amended to increase the
authorized number of shares of MotivePower common stock to 150,000,000 and the
authorized number of shares of MotivePower preferred stock to 15,000,000.

COMMON STOCK

     As of July 19, 1999, 27,019,235 MotivePower shares were issued and
outstanding, no shares were issued and held in MotivePower's treasury and
4,848,750 shares were reserved for issuance upon the exercise of stock options.
The holders of common stock are entitled to one vote per share on all matters to
be voted upon by the shareholders, and there is no cumulative voting in the
election of directors, nor are there preemptive rights upon the issuance of
additional MotivePower shares. Upon dissolution of MotivePower, which does not
include the merger, the holders of MotivePower common stock will be entitled to
a ratable portion of any assets remaining after payment of all priority claims.

PREFERRED STOCK

     MotivePower currently has 1,600,000 shares of preferred stock which have
been designated Series C Junior Participating Preferred Stock for issuance in
connection with MotivePower's shareholder rights plan. The MotivePower board of
directors is authorized to issue shares of preferred stock in classes or series
and to determine for any such class or series its voting rights, preferences,
limitations and any special rights. This action may be taken by the board at
anytime and without shareholder approval. While MotivePower has no current
understandings, plans or agreements for the issuance of preferred stock, the
shares of preferred stock may be used in connection with the raising of
additional capital, future acquisitions, and for other corporate purposes. In
addition, some or all of the preferred stock could be used in connection with
the shareholder rights plan described below.

SHAREHOLDER RIGHTS PLAN

     On January 19, 1996, the board of directors of MotivePower adopted a
shareholder rights plan, which has been subsequently amended by the board, and
declared that a dividend of one share purchase right be distributed on each
outstanding share of common stock to shareholders of record as of the close of
business on January 30, 1996. Each right entitles the registered holder to
purchase from MotivePower one one-hundredth of a share of Series C Preferred
Stock, par value $0.01 per share, or, in some circumstances, shares of common
stock, other securities, and/or cash or other property, at a purchase price of
$80 per share of Series C Preferred Stock or, when applicable, MotivePower
common stock, securities, cash, and/or other property, subject to adjustment.
The complete terms and conditions of the rights are set forth in a rights
agreement dated as of January 19, 1996, as amended, between MotivePower and
ChaseMellon Shareholder Services, L.L.C., as rights agent.

                                      II-15
   95

     All shares of MotivePower common stock currently outstanding have
associated rights and all shares of MotivePower common stock issued at the
effective time of the merger will have associated rights. Initially, the rights
attached to the outstanding shares of common stock without a separate
distribution of right certificates. The rights will detach from the outstanding
shares of common stock and separate right certificates will be issued when there
is a Distribution Date. A "Distribution Date" will occur on (1) the tenth day
following a public announcement that a person has become an Acquiring Person, or
(2) if earlier, the tenth business day, or a later date as may be determined by
the MotivePower board of directors prior to the time any person becomes an
Acquiring Person, following the commencement or announcement of a tender or
exchange offer that would result in a person or group of affiliated or
associated persons becoming the beneficial owner of 10% or more of the
outstanding shares of common stock. Subject to limitations and exceptions
specified in the rights agreement, an "Acquiring Person" is a person or group of
affiliated or associated persons that beneficially owns 10% or more of the
outstanding shares of common stock. The rights are not exercisable until the
Distribution Date and will expire at the close of business on August 22, 2007,
unless the expiration date is extended or unless the rights are earlier redeemed
or exchanged by MotivePower.

     Once a person has become an Acquiring Person, all rights that are, or,
under circumstances specified in the rights agreement, were, beneficially owned
by an Acquiring Person will be null and void. In the event that, at any time
after a person becomes an Acquiring Person, (1) MotivePower is acquired in a
merger or other business combination, or (2) 50% or more of the assets or
earning power of MotivePower and its subsidiaries (taken as a whole) is sold or
otherwise transferred, proper provision will be made so that each holder of a
right, other than a right that is or was beneficially owned by an Acquiring
Person that has become null and void pursuant to the terms of the rights
agreement, shall thereafter have the right to receive upon exercise of that
right, in lieu of shares of Series C Preferred Stock, shares of common stock of
the acquiror then having a current market value equal to two times the
then-current purchase price.

     At any time prior to the time any person becomes an Acquiring Person, the
MotivePower board of directors may redeem the rights in whole, but not in part,
at a price of $0.001 per right, subject to adjustment. The redemption of the
rights may be made effective at such time, on such basis, and with such
conditions as the MotivePower Board in its sole discretion may establish.
Immediately upon any redemption of the rights, the right to exercise the rights
will terminate and the only right of the holders of rights will be to receive
$0.001 per right. Until a right is exercised, the holder thereof, as such, will
have no rights as a shareholder of MotivePower, including, without limitation,
the right to vote or to receive dividends.

     On June 2, 1999, MotivePower amended its rights agreement to render the
rights agreement inapplicable with respect to the merger, to exclude WABCO's
ESOP from the definition of Acquiring Person and to make additional amendments
in connection with MotivePower's reincorporation from Delaware to Pennsylvania.

     The shareholder rights plan was primarily written to meet the standards
established in Delaware case law. Pennsylvania law explicitly approves such
rights plans, but specific plans will probably still be subject to evaluation on
a case-by-case basis. In that regard, differences between Delaware's and
Pennsylvania's court systems and legal precedents could potentially affect the
outcome of any legal challenge to the shareholder rights plan.

TRANSFER AGENT AND REGISTRAR

     ChaseMellon Shareholder Services, L.L.C. is the transfer agent and
registrar for the MotivePower common stock.

STOCK EXCHANGE LISTING; DELISTING AND DEREGISTRATION OF WABCO COMMON STOCK

     It is a condition to the merger that the shares of MotivePower common stock
issuable in the merger be approved for listing on the NYSE at or prior to the
closing, subject to official notice of issuance. If the merger is completed,
WABCO common stock will cease to be listed.

                                 LEGAL MATTERS

     The validity of the MotivePower common stock to be issued to WABCO
shareholders pursuant to the merger will be passed upon by Doepken Keevican &
Weiss. It is a condition to the completion of the merger that MotivePower and
WABCO receive opinions from Sidley & Austin and Kirkland & Ellis with respect to
the tax treatment of the merger. See "The Merger Agreement--Conditions to the
Completion of the Merger" and "The Merger Transaction--Material United States
Federal Income Tax Consequences of the Merger."

     MotivePower filed a registration statement on Form S-4 to register with the
SEC the MotivePower common stock to be issued to WABCO shareholders in the
merger. This joint proxy statement/prospectus is a part of that registration
statement and constitutes a prospectus of MotivePower in addition to being a
proxy statement of MotivePower and WABCO for the meetings. As allowed by SEC
rules, this joint proxy statement/prospectus does not contain all the
information you can find in the registration statement or the exhibits to the
registration statement.

     The SEC allows us to "incorporate by reference" information into this joint
proxy statement/prospectus, which means that we can disclose important
information to you by referring you to another document filed separately with
the SEC. The information incorporated by reference is deemed to be part of this
joint proxy statement/prospectus, except for any information superseded by
information in, or incorporated by reference in, this joint proxy
statement/prospectus. This joint proxy statement/prospectus incorporates by

as amended, between MotivePower Industries, Inc., a Pennsylvania corporation

                              W I T N E S S E T H:

                                   ARTICLE I

                                   THE MERGER

     SECTION 1.1. THE MERGER. Upon the terms and subject to the conditions

   107

The Merger shall become effective on the date and at the time when the last of
the following actions shall have been completed: (i) the Articles of Merger have
been duly filed with the Department of State of the Commonwealth of Pennsylvania
and (ii) the Certificate of Merger has been duly filed with the Secretary of
State of Delaware (the "Effective Time").

     SECTION 1.3. EFFECTS OF THE MERGER. The Merger shall have the effects set
forth in Section 1929 of the PBCL and Section 259 of the DGCL.

     SECTION 1.4. CHARTER AND BY-LAWS; BOARD OF DIRECTORS; MANAGEMENT
SUCCESSION. (a) At the Effective Time, the Articles of Incorporation of
MotivePower, as in effect immediately prior to the Effective Time, shall be
amended as set forth in Exhibit 1.4(a) and such Articles of Incorporation, as so
amended, shall be the Articles of Incorporation of the Surviving Corporation
until thereafter changed or amended as provided therein or by applicable law.
Immediately prior to the Effective Time, the Board of Directors of MotivePower
shall amend and restate the By-Laws of MotivePower as set forth in Exhibit
1.4(a). At the Effective Time, the By-Laws of MotivePower, as amended and
restated immediately prior to the Effective Time, shall be the By-Laws of the
Surviving Corporation until thereafter changed or amended as provided therein or
by the Articles of Incorporation.

     (b) From and after the Effective Time, until duly changed in compliance
with applicable law and the Articles of Incorporation and By-Laws of the
Surviving Corporation, the Board of Directors of the Surviving Corporation shall

who shall hold the office set forth opposite their respective name.

     SECTION 1.5. CONVERSION OF SECURITIES. As of the Effective Time, by virtue
of the Merger and without any action on the part of MotivePower, WABCO or the
holders of any securities of the Constituent Corporations:

     (a) All shares of WABCO Common Stock that are held in the treasury of WABCO
or by any wholly-owned Subsidiary of WABCO and any shares of WABCO Common Stock
owned by MotivePower or by any wholly-owned Subsidiary of MotivePower shall be
cancelled and no capital stock of MotivePower or other consideration shall be
delivered in exchange therefor.

     (b) Subject to the provisions of Sections 1.8 and 1.10 hereof, each share
of WABCO Common Stock issued and outstanding immediately prior to the Effective
Time (other than shares to be cancelled in accordance with Section 1.5(a)) shall
be converted into 1.30 (such number being the "Exchange Ratio") validly issued,
fully paid and nonassessable shares of MotivePower Common Stock. All such shares
of WABCO Common Stock, when so converted, shall no longer be outstanding and
shall automatically be cancelled and retired and each holder of a certificate
representing any such shares shall cease to have any rights with respect
thereto, except the right to receive any dividends and other distributions in
accordance with Section 1.7, certificates representing the shares of MotivePower
Common Stock into which such shares are converted and any cash, without
interest, in lieu of fractional shares to be issued or paid in consideration
therefor upon the surrender of such certificate in accordance with Section 1.6.

     (c) All WABCO Stock Options (as defined in Section 2.2(a)) outstanding at
the Effective Time shall become options to purchase MotivePower Common Stock
pursuant to Section 5.13.

     SECTION 1.6. MOTIVEPOWER TO MAKE CERTIFICATES AVAILABLE. (a) Exchange of
Certificates. MotivePower shall authorize ChaseMellon Shareholder Services,
L.L.C. (or such other person or persons as shall be reasonably acceptable to
MotivePower and WABCO) to act as Exchange Agent hereunder (the "Exchange
Agent"). As soon as practicable after the Effective Time, MotivePower shall
deposit with the Exchange Agent, in trust for the holders of shares of WABCO
Common Stock converted in the Merger,

                                       -2-
   108

certificates representing the shares of MotivePower Common Stock issuable
pursuant to Section 1.5(b) in exchange for outstanding shares of WABCO Common
Stock and cash, as required to make payments in lieu of any fractional shares
pursuant to Section 1.8 (such cash and shares of MotivePower Common Stock,
together with any dividends or distributions with respect thereto, being
hereinafter referred to as the "Exchange Fund"). The Exchange Agent shall
deliver the MotivePower Common Stock contemplated to be issued pursuant to
Section 1.5(b) out of the Exchange Fund.

     (b) Exchange Procedures. As soon as practicable after the Effective Time,
the Exchange Agent shall mail to each record holder of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding shares of WABCO Common Stock converted in the Merger (the
"Certificates") a letter of transmittal (which shall specify that delivery shall
be effected, and risk of loss and title to the Certificates shall pass, only
upon actual delivery of the Certificates to the Exchange Agent, and shall
contain instructions for use in effecting the surrender of the Certificates in
exchange for certificates representing shares of MotivePower Common Stock and
cash in lieu of fractional shares). Upon surrender for cancellation to the
Exchange Agent of all Certificates held by any record holder of a Certificate,
together with such letter of transmittal, duly executed, the holder of such
Certificate shall be entitled to receive in exchange therefor a certificate
representing that number of whole shares of MotivePower Common Stock into which
the shares represented by the surrendered Certificate shall have been converted
at the Effective Time pursuant to this Article I, cash in lieu of any fractional
share in accordance with Section 1.8 and certain dividends and other
distributions in accordance with Section 1.7, and any Certificate so surrendered
shall forthwith be cancelled.

     SECTION 1.7. DIVIDENDS; TRANSFER TAXES; WITHHOLDING. No dividends or other
distributions that are declared on or after the Effective Time on MotivePower
Common Stock, or are payable to the holders of record thereof on or after the
Effective Time, will be paid to any person entitled by reason of the Merger to
receive a certificate representing MotivePower Common Stock until such person
surrenders the related Certificate or Certificates, as provided in Section 1.6,
and no cash payment in lieu of fractional shares will be paid to any such person
pursuant to Section 1.8 until such person shall so surrender the related
Certificate or Certificates. Subject to the effect of applicable law, there
shall be paid to each record holder of a new certificate representing such
MotivePower Common Stock: (i) at the time of such surrender or as promptly as
practicable thereafter, the amount of any dividends or other distributions
theretofore paid with respect to the shares of MotivePower Common Stock
represented by such new certificate and having a record date on or after the
Effective Time and a payment date prior to such surrender; (ii) at the
appropriate payment date or as promptly as practicable thereafter, the amount of
any dividends or other distributions payable with respect to such shares of
MotivePower Common Stock and having a record date on or after the Effective Time
but prior to such surrender and a payment date on or subsequent to such
surrender; and (iii) at the time of such surrender or as promptly as practicable
thereafter, the amount of any cash payable with respect to a fractional share of
MotivePower Common Stock to which such holder is entitled pursuant to Section
1.8. In no event shall the person entitled to receive such dividends or other
distributions be entitled to receive interest on such dividends or other
distributions. If any cash or certificate representing shares of MotivePower
Common Stock is to be paid to or issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it shall be a
condition of such exchange that the Certificate so surrendered shall be properly
endorsed and otherwise in proper form for transfer and that the person
requesting such exchange shall pay to the Exchange Agent any transfer or other
taxes required by reason of the issuance of certificates for such shares of
MotivePower Common Stock in a name other than that of the registered holder of
the Certificate surrendered, or shall establish to the satisfaction of the
Exchange Agent that such tax has been paid or is not applicable. MotivePower or
the Exchange Agent shall be entitled to deduct and withhold from the
consideration otherwise payable pursuant to this Agreement such amounts as
MotivePower or the Exchange Agent is required to deduct and withhold with
respect to the making of such payment under the Code or under any provision of
state, local or foreign tax law. To the extent that amounts are so withheld by
MotivePower or the Exchange Agent and paid to the appropriate authority, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the person in respect of which such deduction and withholding was
made by MotivePower or the Exchange Agent.

                                       -3-
   109

     SECTION 1.8. NO FRACTIONAL SECURITIES. No certificates or scrip
representing fractional shares of MotivePower Common Stock shall be issued upon
the surrender for exchange of Certificates pursuant to this Article I, and no
MotivePower dividend or other distribution or stock split shall relate to any
fractional share, and no fractional share shall entitle the owner thereof to

                                   ARTICLE II

                    REPRESENTATIONS AND WARRANTIES OF WABCO

     Except as disclosed in the letter delivered to MotivePower concurrently
herewith and designated therein as the WABCO Disclosure Letter (the "WABCO
Disclosure Letter"), in each case with specific reference to the Section to
which exception is taken, WABCO hereby represents and warrants to MotivePower as
follows:

     SECTION 2.1. CORPORATE ORGANIZATION. (a) WABCO is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware. WABCO has the corporate power and authority to own or lease all of its
properties and assets and to carry on its business as it is now being conducted,
and is duly licensed or qualified to do business in each jurisdiction in which
the nature of the business conducted by it or the character or location of the
properties and assets owned or leased by it makes such licensing or
qualification necessary, except where the failure to be so licensed or qualified
would not have a Material Adverse Effect on WABCO. As used in this Agreement,
the term "Material Adverse Effect" means, with respect to MotivePower or WABCO,
as the case may be, a material adverse effect on (i) the business, operations,
results of operations or financial condition of such party and its Subsidiaries
taken as a whole or (ii) the ability of such party to consummate the
transactions contemplated hereby. As used in this Agreement, the word
"Subsidiary" means any corporation, partnership, limited liability company,
joint venture or other legal entity of which MotivePower or WABCO, as the case
may be (either alone or through or together with any other Subsidiary), (i)
owns, directly or indirectly, 50% or more of the stock or other equity interests
the holders of which are generally entitled to vote for the election of the
board of directors or other governing body of such corporation, partnership,
limited liability company, joint venture or other legal entity, (ii) is a
general partner, trustee or other entity or person performing similar functions
or (iii) has control (as defined in Rule 405 under the Securities Act of 1933,
as amended (together with the rules and regulations promulgated thereunder, the
"Securities Act")). For all purposes of this Agreement, a "wholly-owned
Subsidiary" shall be deemed to include those entities which, for regulatory or
other local law purposes, have issued nominal ownership interests to persons
other than WABCO or MotivePower or their respective Subsidiaries. True and
complete copies of the Restated Certificate of Incorporation (the "WABCO
Certificate of Incorporation") and Amended and Restated By-Laws of WABCO, as in
effect as of the date of this Agreement, have previously been made available by
WABCO to MotivePower.

     (b) Each WABCO Subsidiary (i) is duly organized and validly existing under
the laws of its jurisdiction of organization, (ii) is duly qualified to do
business and in good standing in all jurisdictions (whether federal, state,
local or foreign) where its ownership or leasing of property or the conduct of
its business requires it to be so qualified and in which the failure to be so
qualified would have a Material Adverse Effect on WABCO and (iii) has all
requisite corporate power and authority to own or lease its properties and
assets and to carry on its business as now conducted.

     (c) The minute books of WABCO accurately reflect in all material respects
all material corporate actions held or taken since January 1, 1997 of its
stockholders and Board of Directors (including committees of the Board of
Directors of WABCO).

                                       -5-
   111

     SECTION 2.2. CAPITALIZATION. (a) The authorized capital stock of WABCO
consists of (i) 100,000,000 shares of WABCO Common Stock, of which, as of May
27, 1999, 33,966,897 shares were issued and outstanding and 13,459,703 shares
were held in treasury, and (ii) 1,000,000 shares of Preferred Stock, par value
$.01 per share, of WABCO (the "WABCO Preferred Stock"), none of which, as of the
date hereof, were designated, issued and outstanding. All of the issued and
outstanding shares of WABCO Common Stock have been duly authorized and validly
issued and are fully paid, nonassessable and free of preemptive rights, with no
personal liability attaching to the ownership thereof. As of the date of this
Agreement, except pursuant to the terms of options issued pursuant to the WABCO
1995 Stock Incentive Plan, as amended (the "1995 Option Plan"), or the 1995
Non-Employee Directors' Fee and Stock Option Plan (the "1995 Director Option
Plan" and, together with the 1995 Option Plan, the "WABCO Stock Plans"), WABCO
does not have and is not bound by any outstanding subscriptions, options,
warrants, calls, commitments or agreements of any character calling for the
purchase or issuance of any shares of WABCO Common Stock or any other equity
securities of WABCO or any securities representing the right to purchase or
otherwise receive any shares of WABCO Common Stock or WABCO Preferred Stock. As
of the date of this Agreement, no shares of WABCO Common Stock or WABCO
Preferred Stock are reserved for issuance, except for 4,800,000 shares of WABCO
Common Stock reserved for issuance upon exercise of stock options granted
pursuant to the WABCO Stock Plans (the "WABCO Stock Options") and 500,000 shares
of WABCO Common Stock reserved for issuance in connection with the WABCO 1998
Employee Stock Purchase Plan (the "ESPP"). Since December 31, 1998, WABCO has
not issued any shares of its capital stock or any securities convertible into or
exercisable for any shares of its capital stock, other than pursuant to the ESPP
and the exercise of WABCO Stock Options granted prior to such date. WABCO has
previously provided MotivePower with a list of the option holders, the date of
each option to purchase WABCO Common Stock granted, the number of shares subject
to each such option, the expiration date of each such option, and the price at
which each such option may be exercised under an applicable WABCO Stock Plan. In
no event will the aggregate number of shares of WABCO Common Stock outstanding
at the Effective Time exceed the number specified in Section 2.2(a) of the WABCO
Disclosure Letter.

     (b) WABCO owns, directly or indirectly, all of the issued and outstanding
shares of capital stock or other equity ownership interests of each of the WABCO
Subsidiaries as set forth in Section 2.2(b) of the WABCO Disclosure Letter, free
and clear of any liens, pledges, charges, encumbrances and security interests
whatsoever ("Liens") other than as set forth in Section 2.2(b) of the WABCO
Disclosure Letter, and all of such shares or equity ownership interests are duly
authorized and validly issued and are fully paid, nonassessable and free of
preemptive rights, with no personal liability attaching to the ownership
thereof. No WABCO Subsidiary has or is bound by any outstanding subscriptions,
options, warrants, calls, commitments or agreements of any character calling for
the purchase or issuance of any shares of capital stock or any other equity
security of such Subsidiary or any securities representing the right to purchase
or otherwise receive any shares of capital stock or any other equity security of
such Subsidiary.

     SECTION 2.3. AUTHORITY; NO VIOLATION. (a) WABCO has full corporate power
and authority to execute and deliver this Agreement and the WABCO Option
Agreement and to consummate the transactions contemplated hereby and thereby.
The execution and delivery of this Agreement and the WABCO Option Agreement and
the consummation of the transactions contemplated hereby and thereby have been
duly and validly approved and declared advisable by the Board of Directors of
WABCO. The Board of Directors of WABCO has directed that this Agreement and the
transactions contemplated hereby be submitted to WABCO's stockholders for
adoption at the WABCO Stockholders Meeting (as defined in Section 5.3) and,
except for the adoption of this Agreement by the affirmative vote of the holders
of a majority of the outstanding shares of WABCO Common Stock, no other
corporate proceedings on the part of WABCO are necessary to approve and adopt
this Agreement and the WABCO Option Agreement and to consummate the transactions
contemplated hereby and thereby. Each of this Agreement and the WABCO Option
Agreement has been duly and validly executed and delivered by WABCO and
(assuming due authorization, execution and delivery by MotivePower of this
Agreement and the WABCO Option Agreement) constitutes a valid and binding
obligation of WABCO, enforceable against WABCO in accordance with its terms.

                                       -6-
   112

     (b) Neither the execution and delivery of this Agreement or the WABCO
Option Agreement by WABCO nor the consummation by WABCO of the transactions
contemplated hereby or thereby, nor compliance by WABCO with any of the terms or
provisions hereof or thereof, will (i) violate any provision of the WABCO
Certificate of Incorporation or the WABCO By-Laws or (ii) assuming that the
consents and approvals referred to in Section 2.4 are duly obtained, (x) violate
any statute, code, ordinance, rule, regulation, judgment, order, writ, decree or

termination or cancellation under, accelerate the performance required by, or
result in the creation of any Lien upon any of the respective properties or
assets of WABCO or any of its Subsidiaries under, any of the terms, conditions
or provisions of any note, bond, mortgage, indenture or other agreement,
instrument for borrowed money, any guarantee of any agreement or instrument for
borrowed money or any license, lease or any other agreement or instrument
("Material Agreement") to which WABCO or any of its Subsidiaries is a party, or
by which they or any of their respective properties or assets may be bound or
affected, except (in the case of clause (y) above) for such violations,
conflicts, breaches or defaults which, either individually or in the aggregate,
will not have a Material Adverse Effect on WABCO.

other governmental authority or instrumentality (each a "Governmental Entity")
or with any third party are necessary in connection with (A) the execution and
delivery by WABCO of this Agreement and the WABCO Option Agreement and (B) the
consummation by WABCO of the Merger and the other transactions contemplated by
this Agreement and the WABCO Option Agreement.

     SECTION 2.5. SEC DOCUMENTS AND OTHER REPORTS. WABCO has filed all required
documents with the SEC since January 1, 1997 (the "WABCO SEC Documents"). As of
their respective dates, the WABCO SEC Documents complied in all material
respects with the requirements of the Securities Act or the Securities Exchange
Act of 1934, as amended (together with the rules and regulations promulgated
thereunder, the "Exchange Act"), as the case may be, and, at the respective
times they were filed, none of the WABCO SEC Documents contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. The consolidated

with applicable accounting requirements and the published rules and regulations
of the SEC with respect thereto as of their respective dates of filing, were

audit adjustments and to any other adjustments described therein). Except as

Joint Proxy Statement or the Registration Statement, such event shall be so
described, and an appropriate amendment or supplement shall be promptly filed
with the SEC and, as required by law, disseminated to the stockholders of WABCO.
The Registration Statement will comply (with respect to WABCO) as to form in all
material respects with the provisions of the Securities Act, and the Joint Proxy
Statement will comply (with respect to WABCO) as to form in all material
respects with the provisions of the Exchange Act.

the WABCO SEC Documents filed prior to the date of this Agreement, since
December 31, 1998, (A) WABCO and its Subsidiaries have not incurred any material

WABCO, (B) WABCO and its Subsidiaries have not sustained any loss or

Tax Returns in prior periods, and (F) there has been no other event causing a
Material Adverse Effect on WABCO, nor any development that would, individually
or in the aggregate, have a Material Adverse Effect on WABCO. Set forth in

on Form 10-K for the year ended December 31, 1998, as filed with the SEC (other
than any changes in, or the incurrence of, indebtedness of WABCO or any of its
Subsidiaries with a principal amount not in excess of $1,000,000).

     SECTION 2.8. PERMITS AND COMPLIANCE. Each of WABCO and its Subsidiaries is
in possession of all franchises, grants, authorizations, licenses, permits,
charters, easements, variances, exceptions, consents, certificates, approvals
and orders of any Governmental Entity (collectively, "Permits") necessary for
WABCO or any of its Subsidiaries to own, lease and operate its properties or to
carry on its business as it is now being conducted (the "WABCO Permits"), except
where the failure to have any of the WABCO Permits would not, individually or in
the aggregate, have a Material Adverse Effect on WABCO, and, as of the date

                                       -8-
   114

of this Agreement, no suspension or cancellation of any of the WABCO Permits is

documents, (ii) any applicable law, ordinance, administrative or governmental
rule or regulation or (iii) any order, decree or judgment of any Governmental
Entity having jurisdiction over WABCO or any of its Subsidiaries, except, in the
case of clauses (i), (ii) and (iii), for any violations that, individually or in
the aggregate, would not have a Material Adverse Effect on WABCO. "Knowledge of
WABCO" means the actual knowledge, after reasonable investigation, of the
individuals identified in Section 2.8 of the WABCO Disclosure Letter.

all federal, and all material state, local, foreign and provincial, Tax Returns
required to have been filed or appropriate extensions therefor have been

has waived any statute of limitations in respect of its Taxes which waiver is
currently in effect; (v) any Tax Returns referred to in clause (i) relating to
federal and state income Taxes have been examined by the Internal Revenue

the date of this Agreement, there are no actions, suits or claims or legal,
administrative or arbitrative proceedings or investigations pending or, to the
Knowledge of WABCO, threatened against or involving WABCO or any of its

on the basis of any of the transactions contemplated by this Agreement. No
holder of any option to purchase shares of WABCO Common Stock, or shares of
WABCO Common Stock granted in connection with the performance of services for
WABCO or its Subsidiaries, is or will be entitled to receive cash from WABCO or
any Subsidiary in lieu of or in exchange for such option or shares as a result
of the transactions contemplated by this Agreement or the WABCO Option

description is required, (v) the most recent actuarial report or valuation
relating to a WABCO Plan subject to Title IV of the Employee Retirement Income
Security Act of 1974 and the regulations promulgated thereunder ("ERISA"), (vi)
the most recent determination letter, if any, issued by the IRS with respect to
any WABCO Plan intended to be qualified under section 401(a) of the Code, (vii)
any request for a determination currently pending before the IRS and (viii) all
correspondence with the IRS, the Department of Labor or the Pension Benefit
Guaranty Corporation relating to any outstanding controversy. Each WABCO Plan
complies with ERISA, the Code and all other applicable statutes and governmental
rules and regulations, except any failure to comply as would not have,
individually or in the aggregate, a Material Adverse Effect on WABCO. Except as
set forth in Section 2.12(a)(Y) of the WABCO Disclosure Letter, (i) no
"reportable event" (within the meaning of Section 4043 of ERISA) has occurred
within the past three years with respect to any WABCO Plan which could result in
liability to WABCO, (ii) neither WABCO nor any of its ERISA Affiliates (as
hereinafter defined) has withdrawn from any WABCO Multiemployer Plan (as
hereinafter defined) at any time or instituted, or is currently considering
taking, any action to do so, and (iii) no action has been taken, or is currently
being considered, to terminate any WABCO Plan subject to Title IV of ERISA.

     (b) There has been no failure to make any contribution or pay any amount
due to any WABCO Plan as required by Section 412 of the Code, Section 302 of
ERISA, or the terms of any such Plan, and no WABCO Plan, nor any trust created
thereunder, has incurred any "accumulated funding deficiency" (as defined in
Section 302 of ERISA), whether or not waived.

     (c) With respect to WABCO Plans, no event has occurred and, to the
Knowledge of WABCO, there exists no condition or set of circumstances in
connection with which WABCO or any of its ERISA Affiliates would be subject to
any liability under the terms of such WABCO Plans, ERISA, the Code or any other
applicable law which has had, or would have, individually or in the aggregate, a
Material Adverse Effect on WABCO. Except as listed on Section 2.12(c) of the
WABCO Disclosure Letter, all WABCO Plans that are intended to be qualified under
Section 401(a) of the Code have been determined by the IRS to be so qualified,
or a timely application for such determination is now pending or will be filed
on a timely basis and, except as listed on Section 2.12(c) of the WABCO
Disclosure Letter, to the Knowledge of WABCO there is no reason why any WABCO
Plan is not so qualified in operation. Neither WABCO nor any of its ERISA
Affiliates has been notified by any WABCO Multiemployer Plan that such WABCO
Multiemployer Plan is currently in reorganization or insolvency under and within
the meaning of Section 4241 or 4245 of ERISA or that such WABCO Multiemployer
Plan intends to terminate or has been terminated under Section
                                      -10-
   116

4041A of ERISA. To the Knowledge of WABCO, neither the termination of any WABCO
Multiemployer Plan nor the complete or partial withdrawal by WABCO or any of its
ERISA Affiliates from any WABCO Multiemployer Plan would result in any liability
of WABCO or any of its ERISA Affiliates that would have, individually or in the
aggregate, a Material Adverse Effect on WABCO. Except as set forth in Section
2.12(c) of the WABCO Disclosure Letter, neither WABCO nor any of its ERISA
Affiliates has any liability or obligation under any welfare plan to provide
life insurance or medical benefits after termination of employment to any
employee or dependent other than as required by (i) Part 6 of Title 1 of ERISA
or (ii) the laws of a jurisdiction outside the United States.

     (d) As used in this Agreement, (i) "WABCO Plan" means a "pension plan" (as
defined in Section 3(2) of ERISA (other than a WABCO Multiemployer Plan (as
hereinafter defined))), a "welfare plan" (as defined in Section 3(1) of ERISA),
or any material bonus, profit sharing, deferred compensation, incentive
compensation, stock ownership, stock purchase, stock option, phantom stock,
vacation, severance, death benefit, insurance or other plan, arrangement or
understanding, in each case established or maintained or contributed to by WABCO
or any of its ERISA Affiliates or as to which WABCO or any of its ERISA
Affiliates or otherwise may have any liability, whether or not covered by ERISA
(other than a WABCO Ex-U.S. Pension Plan (as hereinafter defined)), (ii) "WABCO
Multiemployer Plan" means a "multiemployer plan" (as defined in Section
4001(a)(3) of ERISA) to which WABCO or any of its ERISA Affiliates is or has
been obligated to contribute or otherwise may have any liability, and (iii) with
respect to any person, "ERISA Affiliate" means any corporation or trade or
business (whether or not incorporated) which is under common control, or
otherwise would be considered a single employer with such person pursuant to
Section 414(b), (c), (m) or (o) of the Code and the regulations promulgated
thereunder or pursuant to Section 4001(b) of ERISA and the regulations
promulgated thereunder.

     (e) Section 2.12(e) of the WABCO Disclosure Letter contains a list of each
WABCO Ex-U.S. Pension Plan (as hereinafter defined) and WABCO has provided to
MotivePower a copy of any written plan document. Except as would not have,
individually or in the aggregate, a Material Adverse Effect on WABCO, each such
plan has been maintained in compliance with all applicable laws, orders and
regulations, and the fair market value of the assets of each such plan which is
intended to be a funded WABCO Ex-U.S. Pension Plan or arrangement equals or
exceeds the value of the accrued benefits. As used in this Agreement, the term
"WABCO Ex-U.S. Pension Plan" shall mean any arrangement (other than a WABCO
Plan) providing retirement pension benefits that is established or maintained by
WABCO or any Subsidiary for the benefit of employees who are or were employed
outside the United States.

     (f) Section 2.12(f) of the WABCO Disclosure Letter contains a list, as of
the date of this Agreement, of all (i) severance and employment agreements with
officers of WABCO and each ERISA Affiliate, (ii) severance programs and policies
of WABCO with or relating to its employees and (iii) plans, programs, agreements
and other arrangements of WABCO with or relating to its employees which contain
change of control or similar provisions, in each case involving a severance or
employment agreement or arrangement with an individual officer or employee, only
to the extent such agreement or arrangement provides for minimum annual payments
in excess of $100,000. WABCO has provided to MotivePower a true and complete
copy of each of the foregoing.

     SECTION 2.13. LABOR MATTERS. Except as disclosed in Section 2.13 of the
WABCO Disclosure Letter, neither WABCO nor any of its Subsidiaries is party to
any collective bargaining agreement or other labor agreement with any union or
labor organization and no union or labor organization has been recognized by
WABCO or any of its Subsidiaries as an exclusive bargaining representative for
employees of WABCO or any of its Subsidiaries. Neither WABCO nor any of its
Subsidiaries is the subject of any material proceeding asserting that it or any
of its Subsidiaries has committed an unfair labor practice or is seeking to
compel it to bargain with any labor union or labor organization nor is there
pending or, to the Knowledge of WABCO, threatened, nor has there been for the
past three years, any labor strike, dispute, walkout, work stoppage, slow-down
or lockout involving it or any of its Subsidiaries, except in each case as would
not, individually or in the aggregate, have a Material Adverse Effect on WABCO.

     SECTION 2.14. INTELLECTUAL PROPERTY; YEAR 2000 COMPLIANCE. (a) WABCO and
its Subsidiaries own or have a valid, enforceable right to use free from any
encumbrances, other than those that would not have a Material Adverse Effect on
WABCO, all patents, patent rights, trademarks, trade names, service marks, trade
secrets, copyrights, inventions, know-how, processes, procedures, customer and
supplier lists, computer data, documentation and software, domain names,
applications for registration of any of the foregoing and other proprietary
intellectual property rights (collectively, "Intellectual Property Rights") as
are necessary in connection with the business of WABCO and its Subsidiaries,
taken as a whole, except where the failure to have such Intellectual Property
Rights, individually or in the aggregate, would not have a Material Adverse
Effect on WABCO. Except as set forth in Section 2.14 of the WABCO Disclosure
Letter, neither WABCO nor any of its Subsidiaries has infringed any Intellectual
Property Rights of any third party other than any infringements that,
individually or in the aggregate, would not have a Material Adverse Effect on
WABCO. Neither WABCO nor its Subsidiaries are aware of any infringement or
misappropriation by any person with respect to the Intellectual Property Rights
owned or used by WABCO or its Subsidiaries other than any such infringement or
misappropriation that would not have a Material Adverse Effect on WABCO. All
Intellectual Property Rights owned or used by WABCO or its Subsidiaries as of
the date hereof will be owned or available for use by WABCO and its Subsidiaries
on terms and conditions immediately following the Effective Date that are not
materially different from those existing prior to the Effective Date.

     (b) WABCO and each of its Subsidiaries have conducted a commercially
reasonable inventory and assessment of the hardware, software and embedded
microcontrollers in non-computer equipment (the "Computer Systems") used by
WABCO and its Subsidiaries in its business, in order to determine which parts of
the Computer System are not yet Year 2000 Compliant (as defined below) and to
estimate the cost of rendering such Computer Systems Year 2000 Compliant prior
to January 1, 2000 or such earlier date on which the Computer Systems may shut
down or produce incorrect calculations or otherwise malfunction without becoming
totally inoperable. Based on the above inventory and assessment, the estimated
cost of rendering the Computer Systems Year 2000 Compliant is $10 million, a
portion of which has already been expended and the rest of which has been
included in the current budget adopted by WABCO. For purposes of this Agreement,
"Year 2000 Compliant" means that all of the Computer Systems will correctly
recognize, manipulate and process (including calculating, comparing and
sequencing) date information relating to dates before, on or after January 1,
2000 including leap year calculations, and that the operation and functionality
of such Computer Systems will not be materially adversely affected by the advent
of the year 2000 or any manipulation of data featuring date information relating
to dates before, on or after January 1, 2000.

     SECTION 2.15. ENVIRONMENTAL AND SAFETY MATTERS. (a) Except as set forth in
Section 2.15 of the WABCO Disclosure Letter, the properties, assets and
operations of WABCO and its predecessors and Subsidiaries have complied and are
in compliance with all applicable federal, state, local, regional and foreign
laws, rules and regulations, orders, decrees, common law, judgments, permits and
licenses relating to public and worker health and safety (collectively, "Worker
Safety Laws") and relating to the protection, regulation and clean-up of the
indoor and outdoor environment and activities or conditions related thereto,
including, without limitation, those relating to the generation, handling,
disposal, transportation or release of hazardous or toxic materials, substances,
wastes, pollutants and contaminants including, without limitation, asbestos,
petroleum, radon and polychlorinated biphenyls (collectively, "Environmental
Laws"), except for any violations that, individually or in the aggregate, have
not had, and would not have, a Material Adverse Effect on WABCO. With respect to
such properties, assets and operations, including any previously owned, leased
or operated properties, assets or operations, there are no past, present or
reasonably anticipated future events, conditions, circumstances, activities,
practices, incidents, actions or plans of WABCO or any of its predecessors or
Subsidiaries that would interfere with or prevent compliance or continued
compliance with or give rise to any liabilities or investigatory, corrective or
remedial obligations under applicable Worker Safety Laws and Environmental Laws,
other than any such interference, prevention, liability or obligation that,
individually or in the aggregate, has not had, and would not have, a Material
Adverse Effect on WABCO.

     (b) WABCO and its predecessors and Subsidiaries have not caused or
permitted any property, asset, operation, including any previously owned
property, asset or operation, to use, generate, manufacture, refine, transport,
treat, store, handle, dispose, transfer or process hazardous or toxic materials,
substances, wastes,

                                      -12-
   118

pollutants or contaminants, except in material compliance with all Environmental
Laws and Worker Safety Laws, other than any such activity that, individually or
in the aggregate, has not had, and would not have, a Material Adverse Effect on
WABCO. WABCO and its Subsidiaries have not reported to any Governmental Entity,
or been notified by any Governmental Entity of the existence of, any material
violation of an Environmental Law or any release, discharge or emission of any
hazardous or toxic materials, substances, wastes, pollutants or contaminants,
other than any such violation, release, discharge or emission that, individually
or in the aggregate, has not had, and would not have, a Material Adverse Effect
on WABCO.

     (c) With respect to WABCO, neither this Agreement nor the consummation of
the transactions that are the subject of this Agreement will result in any
obligations for site investigation or cleanup, or notification to or consent of
any Governmental Entity or third party, pursuant to any of the so-called
"transaction-triggered" or "responsible property transfer" Environmental Laws,
other than any such obligations that, individually or in the aggregate, would
not have a Material Adverse Effect on WABCO.

     (d) This Section sets forth the sole representations and warranties of
WABCO with respect to environmental, health or safety matters, including without
limitation all matters arising under Environmental Laws and Worker Safety Laws.

     SECTION 2.16. INSURANCE. WABCO and its Subsidiaries have in effect
insurance coverage with reputable insurers, which in respect of amounts,
premiums, types and risks insured, constitutes reasonably adequate coverage
against all risks customarily insured against by companies of comparable size
and with similar operations.

     SECTION 2.17. PARACHUTE PAYMENTS TO DISQUALIFIED INDIVIDUALS. Except as set
forth in Section 2.17 of the WABCO Disclosure Letter, no payment or other
benefit, and no acceleration of the vesting of any options, payments or other
benefits, will, as a direct or indirect result of the transactions contemplated
by this Agreement, be (or under Section 280G of the Code and the Treasury
Regulations thereunder be presumed to be) a "parachute payment" to a
"disqualified individual" (as those terms are defined in Section 280G of the
Code and the Treasury Regulations thereunder) with respect to WABCO or any of
its Subsidiaries, without regard to whether such payment or acceleration is
reasonable compensation for personal services performed or to be performed in
the future. The approximate aggregate amount of "parachute payments" related to
the matters set forth in such Section 2.17 of the WABCO Disclosure Letter,
assuming the Closing occurs on September 1, 1999 and termination of all listed
individuals without cause on such date is set forth in such Section 2.17 of the
WABCO Disclosure Letter.

     SECTION 2.18. REQUIRED VOTE OF WABCO STOCKHOLDERS. The affirmative vote of
the holders of a majority of the outstanding shares of WABCO Common Stock is
required to adopt this Agreement. No other vote of the stockholders of WABCO is
required by law, the WABCO Certificate of Incorporation or the WABCO By-Laws or
otherwise in order for WABCO to consummate the Merger and the transactions
contemplated by this Agreement and the WABCO Stock Option Agreement.

     SECTION 2.19. STATE TAKEOVER LAWS. The Board of Directors of WABCO has, to
the extent such statute is applicable, taken all action (including appropriate
approvals of the Board of Directors of WABCO) necessary to exempt MotivePower,
its Subsidiaries and affiliates, the Merger, this Agreement, the WABCO Option
Agreement and the transactions contemplated hereby and thereby from Section 203
of the DGCL. To the Knowledge of WABCO, no other state takeover statutes are
applicable to the Merger, this Agreement, the WABCO Option Agreement or the
transactions contemplated hereby or thereby.

     SECTION 2.20. POOLING OF INTERESTS; REORGANIZATION. To the Knowledge of
WABCO, neither it nor any of its Subsidiaries has (i) taken any action or failed
to take any action which action or failure would jeopardize the treatment of the
Merger as a pooling of interests for accounting purposes or (ii) taken any
action or failed to take any action which action or failure would jeopardize the
qualification of the Merger as a reorganization within the meaning of Section
368(a) of the Code.

     SECTION 2.21. OPINION OF FINANCIAL ADVISOR. WABCO has received the written
opinion of Credit Suisse First Boston Corporation, dated the date hereof, to the
effect that, as of the date hereof, the Exchange

                                      -13-
   119

Ratio is fair to WABCO's stockholders from a financial point of view, a copy of
which opinion has been delivered to MotivePower.

     SECTION 2.22. BROKER'S FEES. Except as set forth in the engagement letter
agreement between WABCO and Credit Suisse First Boston Corporation, a true and
complete copy of which has previously been provided to MotivePower, neither
WABCO nor any WABCO Subsidiary nor any of their respective officers or directors
has employed any broker or finder or incurred any liability for any broker's
fees, commissions or finder's fees in connection with the Merger or related
transactions contemplated by this Agreement or the WABCO Option Agreement.

     SECTION 2.23. UNLAWFUL PAYMENTS AND CONTRIBUTIONS. To the Knowledge of
WABCO, neither WABCO, any Subsidiary nor any of their respective directors,
officers or any of their respective employees or agents has (i) used any WABCO
funds for any unlawful contribution, endorsement, gift, entertainment or other
unlawful expense relating to political activity; (ii) made any direct or
indirect unlawful payment to any foreign or domestic government official or
employee; (iii) violated or is in violation of any provision of the Foreign
Corrupt Practices Act of 1977, as amended; or (iv) made any bribe, rebate,
payoff, influence payment, kickback or other unlawful payment to any person.

     SECTION 2.24. REAL PROPERTY. (a) Section 2.24(a) of the WABCO Disclosure
Letter lists each material parcel of real property owned by WABCO or any of its
Subsidiaries (the "WABCO Owned Property"). WABCO or its applicable Subsidiary
has good and marketable title in and to all of the WABCO Owned Property, subject
to no Liens that would have a Material Adverse Effect on WABCO or materially
impair WABCO's rights to or ability to use any such property, except as
described on Section 2.24(a) of the WABCO Disclosure Letter.

     (b) Section 2.24(b) of the WABCO Disclosure Letter sets forth a list of all
material leases, subleases and other occupancy agreements, including all
amendments, extensions and other modifications (the "WABCO Leases") for real
property (the "WABCO Leased Property"; the WABCO Owned Property and the WABCO
Leased Property collectively the "WABCO Real Property") to which WABCO or any of
its Subsidiaries is a party. WABCO or its applicable Subsidiary has a good and
valid leasehold interest in and to all of the WABCO Leased Property, subject to
no Liens except as described in Section 2.24(b) of the WABCO Disclosure Letter.
Each WABCO Lease is in full force and effect and is enforceable in accordance
with its terms. There exists no default or condition which, with the giving of
notice, the passage of time or both, could become a default under any WABCO
Lease in any case, that would have a Material Adverse Effect on WABCO or
materially impair WABCO's rights to or ability to use any such property. WABCO
has previously delivered to MotivePower true and complete copies of all the
WABCO Leases. Except as described on Section 2.24(b) of the WABCO Disclosure
Letter, no consent, waiver, approval or authorization is required from the
landlord under any WABCO Lease as a result of the execution of this Agreement or
the consummation of the transactions contemplated hereby the failure to obtain
would have a Material Adverse Effect on WABCO or materially impair WABCO's
rights to or ability to use any such property.

     SECTION 2.25. MATERIAL CONTRACTS. There have been made available to
MotivePower, its affiliates and their representatives true and complete copies
of all of the following contracts to which WABCO or any of its Subsidiaries is a
party or by which any of them is bound (collectively, the "WABCO Material
Contracts"): (i) contracts with any current officer or director of WABCO or any
of its Subsidiaries; (ii) contracts for the sale of any of the assets of WABCO
or any of its Subsidiaries other than in the ordinary course of business or for
the grant to any person of any preferential rights to purchase any of its assets
other than inventory in the ordinary course of business; (iii) contracts
containing covenants of WABCO or any of its Subsidiaries not to compete in any
line of business or with any person in any geographical area or covenants of any
other person not to compete with WABCO or any of its Subsidiaries in any line of
business or in any geographical area; (iv) material indentures, credit
agreements, mortgages, promissory notes, and all contracts relating to the
borrowing of money; and (v) all other agreements contracts or instruments which,
in the reasonable opinion of WABCO, are material to WABCO or any of its
Subsidiaries. Except as set forth in Section 2.25 of the WABCO Disclosure Letter
or as would not have a Material Adverse Effect on WABCO, all of the WABCO
Material Contracts are in full force and effect and are the legal, valid and
binding

                                      -14-
   120

obligation of WABCO or its Subsidiaries, enforceable against them in accordance
with their respective terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium and similar laws affecting creditors' rights and
remedies generally and subject, as to enforceability, to general principles of
equity (regardless of whether enforcement is sought in a proceeding at law or in
equity). Except as set forth in Section 2.25 of the WABCO Disclosure Letter,
neither WABCO nor any Subsidiary is in default in any material respect under any
WABCO Material Contract nor, to the Knowledge of WABCO, is any other party to
any WABCO Material Contract in default thereunder in any material respect
except, in each case, for those defaults that, individually or in the aggregate,
would not have a Material Adverse Effect on WABCO.

     SECTION 2.26. WARRANTIES. To WABCO's Knowledge, the accrual for warranty
related expenses as of December 31, 1998 reported in WABCO's audited financial
statement contained in WABCO's Form 10-K for the year ended December 31, 1998,
adequately reflects an amount required for satisfaction of warranty claims due
in respect of goods sold or services provided by WABCO or any of its
Subsidiaries prior to such date. Such provision has been established in
accordance with GAAP. Neither WABCO nor its Subsidiaries have agreed to provide
any express product or service warranties other than (a) standard warranties,
the terms of which have been provided to MotivePower and identified as WABCO's
standard warranties, (b) warranties that (i) parts and components are free from
defects in workmanship or comply with standard or agreed specifications that are
extended for terms of no more than two (2) years each and that expressly provide
that cure is to be effected by repair or replacement of the defective or
noncomplying products and (ii) original equipment is free from defects in
workmanship or complies with standard or agreed specifications that are extended
for terms of no more than seven (7) years each and that expressly provide that
cure is to be effected by repair or replacement of the defective or noncomplying
products and (c) other warranties that, individually or in the aggregate, will
not, if material claims are made thereunder, have a Material Adverse Effect on
WABCO.

     SECTION 2.27. POOLING LETTER. WABCO has received a letter from Arthur
Andersen LLP dated as of June 2, 1999 and addressed to WABCO, a copy of which
has been delivered to MotivePower, in which Arthur Andersen LLP concurs with the
WABCO management's conclusions that, as of June 2, 1999, no conditions exist
related to WABCO that would preclude MotivePower from accounting for the Merger
as a pooling of interests.

                                  ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF MOTIVEPOWER

     Except as disclosed in the letter delivered to WABCO concurrently herewith
and designated therein as the MotivePower Disclosure Letter (the "MotivePower
Disclosure Letter"), in each case with specific reference to the Section to
which exception is taken, MotivePower hereby represents and warrants to WABCO as
follows:

     SECTION 3.1. CORPORATE ORGANIZATION. (a) MotivePower is a corporation duly
organized, validly existing and in good standing under the laws of the
Commonwealth of Pennsylvania. MotivePower has the corporate power and authority
to own or lease all of its properties and assets and to carry on its business as
it is now being conducted, and is duly licensed or qualified to do business in
each jurisdiction in which the nature of the business conducted by it or the
character or location of the properties and assets owned or leased by it makes
such licensing or qualification necessary, except where the failure to be so
licensed or qualified would not have a Material Adverse Effect on MotivePower.
True and complete copies of the Articles of Incorporation (the "MotivePower
Articles of Incorporation") and By-Laws of MotivePower, as in effect as of the
date of this Agreement, have previously been made available by MotivePower to
WABCO.

     (b) Each MotivePower Subsidiary (i) is duly organized and validly existing
under the laws of its jurisdiction of organization, (ii) is duly qualified to do
business and in good standing in all jurisdictions (whether federal, state,
local or foreign) where its ownership or leasing of property or the conduct of
its business requires it to be so qualified and in which the failure to be so
qualified would have a Material

                                      -15-
   121

Adverse Effect on MotivePower and (iii) has all requisite corporate power and
authority to own or lease its properties and assets and to carry on its business
as now conducted.

     (c) The minute books of MotivePower accurately reflect in all material
respects all material corporate actions held or taken since January 1, 1997 of
its shareholders and Board of Directors (including committees of the Board of
Directors of MotivePower).

     SECTION 3.2. CAPITALIZATION. (a) The authorized capital stock of
MotivePower consists of (i) 55,000,000 shares of MotivePower Common Stock, of
which, as of May 27, 1999, 27,019,235 shares were issued and outstanding and no
shares were held in treasury, and (ii) 10,000,000 shares of Preferred Stock, par
value $.01 per share, of MotivePower (the "MotivePower Preferred Stock"),
1,600,000 shares of which, as of the date hereof, have been designated Series C
Junior Participating Preferred Stock (the "MotivePower Series C Preferred
Stock") and none of which, as of the date hereof, were, issued and outstanding.
All of the issued and outstanding shares of MotivePower Common Stock have been
duly authorized and validly issued and are fully paid, nonassessable and free of
preemptive rights, with no personal liability attaching to the ownership
thereof. As of the date of this Agreement, except pursuant to (i) the terms of
options granted pursuant to MotivePower Stock Incentive Plan (the "MotivePower
Option Plan") or MotivePower Stock Option Plan for Non-Employee Directors (the
"MotivePower Director Option Plan" and, together with MotivePower Option Plan,
the "MotivePower Stock Plans"), (ii) the rights to purchase MotivePower Series C
Preferred Stock (the "MotivePower Rights"), issued pursuant to the Rights
Agreement, dated as of January 19, 1996, as amended (the "MotivePower Rights
Agreement"), between MotivePower and Chemical Mellon Shareholder Services,
L.L.C., (iii) the Stock Appreciation Right Agreement, dated as of July 1, 1996,
between MotivePower and Michael A. Wolf and (iv) this Agreement, MotivePower
does not have and is not bound by any outstanding subscriptions, options,
warrants, calls, commitments or agreements of any character calling for the
purchase or issuance of any shares of MotivePower Common Stock or any other
equity securities of MotivePower or any securities representing the right to
purchase or otherwise receive any shares of MotivePower Common Stock or
MotivePower Preferred Stock.

     As of the date of this Agreement, no shares of MotivePower Common Stock or
MotivePower Preferred Stock are reserved for issuance, except for 3,205,000
shares of MotivePower Common Stock reserved for issuance upon exercise of stock
options issued pursuant to the MotivePower Stock Plans. Since December 31, 1998,
MotivePower has not issued any shares of its capital stock or any securities
convertible into or exercisable for any shares of its capital stock, other than
pursuant to the exercise of employee stock options granted prior to such date.
MotivePower has previously provided WABCO with a list of the option holders, the
date of each option to purchase MotivePower Common Stock granted, the number of
shares subject to each such option, the expiration date of each such option, and
the price at which each such option may be exercised under an applicable
MotivePower Stock Plan. In no event will the aggregate number of shares of
MotivePower Common Stock outstanding immediately prior to the Effective Time
exceed the number specified in Section 3.2(a) of the MotivePower Disclosure
Letter.

     (b) MotivePower owns, directly or indirectly, all of the issued and
outstanding shares of capital stock or other equity ownership interests of each
of the MotivePower Subsidiaries as set forth in Section 3.2(b) of the
MotivePower Disclosure Letter, free and clear of any Liens other than as set
forth in Section 3.2(b) of the MotivePower Disclosure Letter, and all of such
shares or equity ownership interests are duly authorized and validly issued and

Benefit Guaranty Corporation relating to any outstanding controversy. Each
MotivePower Plan complies with ERISA, the Code and all other applicable statutes
and governmental rules and regulations, except any failure to comply as would
not have, individually or in the aggregate, a Material Adverse Effect on
MotivePower. Except as set forth in Section 3.12 of the MotivePower Disclosure
Letter, (i) no "reportable event" (within the meaning of Section 4043 of ERISA)
has occurred within the past three years with respect to any MotivePower Plan
which could result in liability to MotivePower, (ii) neither MotivePower nor any

defined in Section 302 of ERISA), whether or not waived.

     (c) With respect to MotivePower Plans, no event has occurred and, to the
Knowledge of MotivePower, there exists no condition or set of circumstances in

Section 3.12(c) of the MotivePower Disclosure Letter, all MotivePower Plans that

4041A of ERISA. To the Knowledge of MotivePower, neither the termination of any

     SECTION 3.24. UNLAWFUL PAYMENTS AND CONTRIBUTIONS. To the Knowledge of
MotivePower, neither MotivePower, any Subsidiary nor any of their respective
directors, officers or any of their respective employees or agents has (i) used

     SECTION 3.25. REAL PROPERTY. (a) Section 3.25(a) of the MotivePower
Disclosure Letter lists each parcel of real property owned by MotivePower or any
of its Subsidiaries (the "MotivePower Owned Property"). MotivePower or its
applicable Subsidiary has good and marketable title in and to all of the
MotivePower Owned Property, subject to no Liens that would have a Material
Adverse Effect on MotivePower or materially impair MotivePower's rights to or
ability to use any such property, except as described on Section 3.25(a) of the
MotivePower Disclosure Letter.

     (b) Section 3.25(b) of the MotivePower Disclosure Letter sets forth a list
of all material leases, subleases and other occupancy agreements, including all
amendments, extensions and other modifications (the "MotivePower Leases") for
real property (the "MotivePower Leased Property"; the MotivePower Owned Property
and the MotivePower Leased Property collectively the "MotivePower Real
Property") to which MotivePower or any of its Subsidiaries is a party.
MotivePower or its applicable Subsidiary has a good and valid leasehold interest
in and to all of the MotivePower Leased Property, subject to no Liens except as
described in Section 3.25(b) of the MotivePower Disclosure Letter. Each
MotivePower Lease is in full force and effect and is enforceable in accordance
with its terms. There exists no default or condition which, with the giving of
notice, the passage of time or both, could become a default under any
MotivePower Lease in any case, that would have a Material Adverse Effect on
MotivePower or materially impair MotivePower's rights to or ability to use any
such property. MotivePower has previously delivered to WABCO true and complete
copies of all the MotivePower Leases. Except as described on Section 3.25(b) of
the MotivePower Disclosure Letter, no consent, waiver, approval or authorization
is required from the landlord under any MotivePower Lease as a result of the
execution of this Agreement or the consummation of the transactions contemplated
hereby the failure to obtain would have a Material Adverse Effect on MotivePower
or materially impair MotivePower's rights to or ability to use any such
property.

     SECTION 3.26. MATERIAL CONTRACTS. Except as set forth in Section 3.26 of
the MotivePower Disclosure Letter, there have been made available to WABCO, its
affiliates and their representatives true and complete copies of all of the
following contracts to which MotivePower or any of its Subsidiaries is a party
or by which any of them is bound (collectively, the "MotivePower Material
Contracts"): (i) contracts with any current officer or director of MotivePower
or any of its Subsidiaries; (ii) contracts for the sale of any of the assets of
MotivePower or any of its Subsidiaries other than in the ordinary course of
business or for the grant to any person of any preferential rights to purchase
any of its assets other than inventory in the ordinary course of business; (iii)
contracts containing covenants of MotivePower or any of its Subsidiaries not to
compete in any line of business or with any person in any geographical area or
covenants of any other person not to compete with MotivePower or any of its
Subsidiaries in any line of business or in any geographical area; (iv) material
indentures, credit agreements, mortgages, promissory notes, and all contracts
relating to the borrowing of money; and (v) all other agreements contracts or
instruments which, in the reasonable opinion of MotivePower, are material to
MotivePower or any of its Subsidiaries. Except as set forth or as would not have
a Material Adverse Effect on MotivePower, all of the MotivePower Material
Contracts are in full force and effect and are the legal, valid and binding
obligation of MotivePower or its Subsidiaries, enforceable against them in
accordance with their respective terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium and similar laws affecting creditors'
rights and remedies generally and subject, as to enforceability, to general
principles of equity (regardless of whether enforcement is sought in a
proceeding at law or in equity). Except as set forth in Section 3.26 of the
MotivePower Disclosure Letter, neither MotivePower nor any Subsidiary is in
default in any material respect under any MotivePower Material Contract nor, to
the Knowledge of MotivePower, is any other party to any MotivePower Material
Contract in

                                      -24-
   130

default thereunder in any material respect except, in each case, for those
defaults that, individually or in the aggregate, would not have a Material
Adverse Effect on MotivePower.

     SECTION 3.27. WARRANTIES. To MotivePower's Knowledge, the accrual for
warranty related expenses as of December 31, 1998 reported in MotivePower's
audited financial statement contained in MotivePower's Form 10-K for the year
ended December 31, 1998, adequately reflects an amount required for satisfaction
of warranty claims due in respect of goods sold or services provided by
MotivePower or any of its Subsidiaries prior to such date. Such provision has
been established in accordance with GAAP. Except as set forth in Section 3.27 of
the MotivePower Disclosure Letter, neither MotivePower nor its Subsidiaries have
agreed to provide any express product or service warranties other than (a)
standard warranties, the terms of which have been provided to MotivePower and
identified as MotivePower's standard warranties, (b) warranties that products
are free from defects in workmanship or comply with standard or agreed
specifications that are extended for terms of no more than two (2) years each
and that expressly provide that cure is to be effected by repair or replacement
of the defective or noncomplying products and (c) other warranties that,
individually or in the aggregate, will not, if material claims are made
thereunder, have a Material Adverse Effect on MotivePower.

     SECTION 3.28. POOLING LETTER. MotivePower has received a draft of a letter
(the "Draft Letter") from Deloitte & Touche LLP and addressed to MotivePower, a
copy of which has been delivered to WABCO, in which Deloitte & Touche LLP
concurs with the MotivePower management's conclusions that no conditions exist
related to MotivePower that would preclude MotivePower from accounting for the
Merger as a pooling of interests. MotivePower has also received a letter from
Deloitte & Touche LLP dated as of June 2, 1999 and addressed to MotivePower, a
copy of which has been delivered to WABCO, whereby Deloitte & Touche LLP states,
subject to certain conditions precedent, that it expects to able to issue the
Draft Letter at the Closing.

(iii) participate in any discussions or negotiations regarding, or furnish to

required by the fiduciary obligations of the Board of Directors of WABCO or
MotivePower, as the case may be, as determined in good faith by a majority of
the members thereof (after consultation with outside legal counsel), such party
may, in response to unsolicited requests therefor, participate in discussions or

Superior Proposal. Each of WABCO and MotivePower immediately shall cease and

majority of the members of the Board of Directors of WABCO or MotivePower, as
the case may be, determines in good faith (taking into account the advice of
independent financial advisors) to be more favorable to WABCO or MotivePower, as

revised proposal made by the other party to this Agreement) and for which
financing, to the extent required, is then fully committed, and (iii) a
"Significant Subsidiary" means any Subsidiary that would constitute a
"significant subsidiary" within the meaning of Rule 1-02 of Regulation S-X of
the SEC.

or modify its approval or recommendation of this Agreement or the Merger and
(ii) nothing contained in this Agreement shall prevent the Board of Directors of
WABCO or MotivePower from complying with Rule 14d-9 and Rule 14e-2 promulgated
under the Exchange Act with regard to a Takeover Proposal.

in no event later than 24 hours) after receipt by WABCO or MotivePower (or its
advisors), respectively, of any Takeover Proposal or any request for nonpublic
information in connection with a Takeover Proposal or for access to the
properties, books or records of such party by any Person or entity that informs
such party that it is considering making, or has made, a Takeover Proposal. Such
notice to the other party shall be made orally and in writing and shall indicate
the identity of the offeror and the terms and conditions of such proposal,
inquiry or contact. Such party shall keep the other party informed, on a current
basis, of the status and details (including amendments or proposed amendments)
of any such Takeover Proposal or request and the status of any negotiations or
discussions.

     (d) During the period from the date of this Agreement through the Effective

provision of any confidentiality, standstill or similar agreement to which
WABCO, MotivePower or any of their respective Subsidiaries is a party and which
relates to any transaction that could constitute a Takeover Proposal or that has
as a counterparty any Person making a Takeover Proposal. During such period,
each of WABCO and MotivePower agrees to enforce, to the fullest extent permitted
under applicable law, the provisions of any such agreements, including using its
best efforts to obtain injunctions to prevent any threatened or actual breach of
such agreements and to enforce specifically the terms and any provision thereof

shall prepare and file with the SEC the Registration Statement (in which the
Joint Proxy Statement will be included). WABCO will be given the opportunity to
review and comment upon the Registration Statement. MotivePower and WABCO shall
use their reasonable best efforts to cause the Registration Statement to become
effective under the Securities Act as soon after such filing as practicable. The

of WABCO in favor of approval and adoption of this Agreement and the Merger,
except to the extent the Board of Directors of WABCO, in accordance with the
terms of Section 5.1(b), shall have withdrawn or modified its approval or
recommendation of this Agreement or the Merger, and the recommendation of the
Board of Directors of MotivePower in favor of approval and adoption of this
Agreement and the Merger, except to the extent the Board of Directors of

     (b) MotivePower and WABCO shall make all necessary filings with respect to
the Merger and the transactions contemplated thereby under the Securities Act
and the Exchange Act and applicable "Blue Sky" laws and the rules and
regulations thereunder. No filing of, or amendment or supplement to, the
Registration Statement or the Joint Proxy Statement will be made by MotivePower
or WABCO without providing the other party the opportunity to review and comment
thereon. MotivePower will advise WABCO, promptly after it receives notice
thereof and in any event within 24 hours thereof, of the time when the

of the MotivePower Common Stock issuable in connection with the Merger for
offering or sale in any jurisdiction, or any request by the SEC for amendment of
the Registration Statement or comments thereon and responses thereto or requests
by the SEC for additional information. If at any time prior to the Effective
Time any information relating to MotivePower or WABCO, or any of their
respective affiliates, officers or directors, should be discovered by
MotivePower or WABCO which should be set forth in an amendment or supplement to
any of the Registration Statement or the Joint Proxy Statement, so that any of
such documents would not include any misstatement of a material fact or omit to
state any material fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading, the party which
discovers such information shall promptly notify the other parties

                                      -30-
   136

hereto and an appropriate amendment or supplement describing such information
shall be promptly filed with the SEC and, to the extent required by law,
disseminated to the shareholders of MotivePower and WABCO.

     SECTION 5.3. SHAREHOLDERS MEETINGS. WABCO shall duly call, give notice of,
convene and hold a meeting of its stockholders (the "WABCO Stockholders
Meeting") for the purpose of voting on the adoption and approval of this

to the extent that the Board of Directors of WABCO shall have withdrawn or
modified its approval or recommendation of this Agreement and the Merger as
permitted by Section 5.1(b). MotivePower shall duly call, give notice of,
convene and hold a meeting of its shareholders (the "MotivePower Shareholders
Meeting" and, together with the WABCO Stockholders Meeting, the "Shareholders

Agreement and the Merger and, through its Board of Directors, will recommend to
its shareholders adoption and approval of this Agreement and the Merger, except
to the extent that the Board of Directors of MotivePower shall have withdrawn or
modified its approval or recommendation of this Agreement and the Merger as

best efforts to hold the MotivePower Shareholders Meeting and the WABCO
Stockholders Meeting on the same date and as soon as practicable after the date
hereof. Except to the extent that the Board of Directors of WABCO shall have
withdrawn or modified its approval or recommendation as aforesaid, WABCO will
use its reasonable best efforts to solicit from its stockholders proxies in
favor of adoption and approval of this Agreement and the Merger. Except to the
extent that the Board of Directors of MotivePower shall have withdrawn or
modified its approval or recommendation as aforesaid, MotivePower will use its
reasonable best efforts to solicit from its shareholders proxies in favor of
adoption and approval of this Agreement and the Merger. This Agreement shall be
submitted to WABCO's stockholders at the WABCO Stockholders Meeting whether or
not the Board of Directors of WABCO determines at any time that this Agreement
is no longer advisable and recommends that the stockholders reject it. This
Agreement shall be submitted to MotivePower's shareholders at the MotivePower
Shareholders Meeting whether or not the Board of Directors of MotivePower
determines at any time that this Agreement is no longer advisable and recommends
that shareholders reject it.

     SECTION 5.4. ACCESS TO INFORMATION. Upon reasonable notice and subject to
applicable law and other legal obligations, each of WABCO and MotivePower shall,
and shall cause each of its Subsidiaries to, afford to the officers, employees,
accountants, counsel and other representatives of the other, access, during the
period prior to the Effective Time, to all its properties, books, contracts,
commitments and records and, during such period, each of WABCO and MotivePower
shall, and shall cause each of its Subsidiaries to, furnish promptly to the
other (a) a copy of each report, schedule, registration statement and other
document filed or received by it during such period pursuant to the requirements
of federal securities laws and (b) all other information concerning its
business, properties and personnel as such other party may reasonably request.
Unless otherwise required by law, the parties will hold any such information
which is nonpublic in confidence in accordance with the Mutual Confidentiality
Agreement dated as of March 15, 1999 between MotivePower and WABCO (the

any representation or warranty contained in this Agreement or the conditions to
the obligations of the parties to consummate the Merger.

     SECTION 5.5. NOTICES OF CERTAIN EVENTS. (a) MotivePower and WABCO shall
promptly notify each other of:

          (i) any notice or other communication from any Person alleging that
     the consent of such Person is or may be required in connection with the
     transactions contemplated by this Agreement, the WABCO Option Agreement or
     the MotivePower Option Agreement; and

          (ii) any notice or other communication from any Governmental Entity in

     (b) WABCO shall promptly notify MotivePower of any actions, suits, claims,

                                      -31-
   137

would have been required to have been disclosed pursuant to Section 2.10 or
which relate to the consummation of the transactions contemplated by this
Agreement, the WABCO Option Agreement or the MotivePower Option Agreement. In
addition, WABCO shall promptly notify MotivePower of (a) (i) it becoming aware
of any fact or event which would be reasonably likely to demonstrate that any
representation or warranty of any party hereto contained in this Agreement was
or is untrue or inaccurate in any material respect as of the date of this
Agreement or (ii) the occurrence or non-occurrence of any fact or event which
would be reasonably likely to cause any material covenant, condition or
agreement of any party hereto under this Agreement not to be complied with or
satisfied in all material respects and (b) any failure of any party hereto to

would be reasonably likely to cause any material covenant, condition or
agreement of any party hereto under this Agreement not to be complied with or
satisfied in all material respects and (b) any failure of any party hereto to
comply with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it hereunder in any material respect; provided, however, that no
such notification shall affect the representations or warranties of any party or
the conditions to the obligations of any party hereunder.

     SECTION 5.6. APPROPRIATE ACTION; CONSENTS; FILINGS. (a) (i) Subject to the
terms and conditions of this Agreement and except to the extent that (x) the
Board of Directors of WABCO shall have withdrawn or modified its approval or
recommendation of this Agreement or the Merger or (y) the Board of Directors of
MotivePower shall have withdrawn or modified its approval or recommendation of
this Agreement or the Merger, in each case as permitted by Section 5.1(b),
MotivePower and WABCO shall use their reasonable best efforts to (A) take, or
cause to be taken, all actions, and do, or cause to be done, all things,
necessary, proper or advisable under applicable laws to consummate the Merger
and the other transactions contemplated by this Agreement as promptly as

permits, waivers, approvals, authorizations or orders required to be obtained or

action or proceeding by any Governmental Entity (including, without limitation,
those in connection with the HSR Act), in connection with the authorization,
execution and delivery of this Agreement and the consummation of the
transactions contemplated herein, and (C) make all necessary filings, and
thereafter make any other required submissions, with respect to this Agreement
and the Merger required under the Securities Act, the Exchange Act and any other
applicable law; provided, however, that MotivePower and WABCO shall cooperate
with each other in connection with the making of all such filings, including
providing copies of all such documents to the non-filing party and its advisors
prior to filing and, if requested, accepting all reasonable additions, deletions
or changes suggested in connection therewith. MotivePower and WABCO shall
furnish to each other all information required for any application or other
filing to be made pursuant to the rules and regulations of any applicable law in
connection with the transactions contemplated by this Agreement. Subject to the
terms and conditions of this Agreement and except to the extent that (x) the
Board of Directors of WABCO shall have withdrawn or modified its approval or
recommendation of this Agreement or the Merger or (y) the Board of Directors of
MotivePower shall have withdrawn or modified its approval or recommendation of
this Agreement or the Merger, in each case as permitted by Section 5.1(b),
MotivePower and WABCO shall not take any action, or refrain from taking any

MotivePower and WABCO to consummate the transactions contemplated by this
Agreement.

                                      -32-
   138

     (ii) Notwithstanding any other provision of this Agreement and except as
provided in Section 5.6(a)(iii), in connection with seeking any approval of a
Governmental Entity relating to this Agreement or the consummation of the
transactions contemplated hereby, without the other party's prior written
consent, neither party shall, and neither party shall be required to, commit to
any divestiture transaction, agree to sell or hold separate, before or after the
Effective Time, any of MotivePower's or WABCO's businesses, product lines,
properties or assets, or agree to any changes or restrictions in the operation
of such businesses, product lines, properties or assets, in any such case if
such divestiture or such restrictions would, individually or in the aggregate,
be reasonably expected to have a material adverse effect on the financial
condition or results of operations of MotivePower and its Subsidiaries, taken as
a whole, after giving effect to the Merger.

     (b) In furtherance and not in limitation of the foregoing, the parties
shall use reasonable best efforts to resolve such objections, if any, as may be
asserted with respect to the transactions contemplated by this Agreement under
any antitrust, competition or trade regulatory laws, rules or regulations of any
domestic or foreign government or governmental authority or any multinational
authority ("Antitrust Laws"). If any suit is instituted challenging any of the
transactions contemplated by this Agreement as violative of any Antitrust Law,
the parties shall take such action (including without limitation, agreeing to
hold separate or to divest any of the businesses, product lines or assets of
WABCO or its Subsidiaries or of MotivePower or its Subsidiaries (a "Business
Unit") (but only if the Business Units required to be held separate or divested
do not in the aggregate have a fair market value of more than $25,000,000 or
revenues for the most recently completed 12 months of more than $25,000,000) as
may be required (a) by the applicable government or governmental or
multinational authority (including, without limitation, the Antitrust Division
of the United States Department of Justice or the Federal Trade Commission) in
order to resolve such objections as such government or authority may have to
such transactions under such Antitrust Law, or (b) by any domestic or foreign
court or similar tribunal, in any suit brought by a private party or
governmental or multinational authority challenging the transactions
contemplated by this Agreement as violative of any Antitrust Law, in order to
avoid the entry of, or to effect the dissolution of, any injunction, temporary
restraining order or other order that has the effect of preventing the
consummation of any of such transactions. The entry by a court, in any suit
brought by a private party or governmental or multinational authority
challenging the transactions contemplated by this Agreement as violative of any
Antitrust Law, of an order or decree permitting the transactions contemplated by
this Agreement, but requiring that any Business Unit of WABCO or its
Subsidiaries or MotivePower or its Subsidiaries be divested or held separate
(but only if such Business Units required to be held separate or divested do not
in the aggregate have a fair market value of more than $25,000,000 or revenues
for the most recently completed 12 months of more than $25,000,000), or that
would otherwise limit the Surviving Corporation's freedom of action with respect
to, or its ability to retain, the Subsidiaries, other assets or businesses of
the Constituent Corporations, shall not be deemed a failure to satisfy the
conditions specified in Section 6.1(b) or Section 6.1(c) hereof.

     (c) (i) MotivePower and WABCO shall give, or shall cause their respective
Subsidiaries to give, any notices to third parties, and use, and cause their
respective Subsidiaries to use, their reasonable best efforts to obtain any
third party consents (A) necessary, proper or advisable in order to consummate
the transactions contemplated by this Agreement or (B) required to prevent a
Material Adverse Effect on MotivePower or a Material Adverse Effect on WABCO
from occurring prior to or after the Effective Time.

     (ii) In the event that either party shall fail to obtain any third party
consent described in Section 5.6(b)(i) above, such party shall use its
reasonable best efforts, and shall take any such actions reasonably requested by
the other party hereto, to minimize any adverse effect upon MotivePower and
WABCO, their respective Subsidiaries, and their respective businesses resulting,
or which could reasonably be expected to result after the Effective Time, from
the failure to obtain such consent.

     SECTION 5.7. PUBLIC DISCLOSURE. MotivePower and WABCO shall consult with
each other before issuing any press release or otherwise making any public
statement with respect to the Merger or this Agreement or the transactions
contemplated hereby and shall not issue any such press release or make any such
public statement prior to such consultation and the receipt of approval therefor
by the other party, which consent shall not be unreasonably withheld, except as
may be required by law, court process or by stock exchange rules.
                                      -33-
   139

     SECTION 5.8. REORGANIZATION; POOLING OF INTERESTS. MotivePower shall make
(to the extent it can truthfully do so) the representations of MotivePower
contained in a certificate of MotivePower (the "MotivePower Tax Certificate")
substantially to the effect of the MotivePower Tax Certificate contained in the
MotivePower Disclosure Letter, and WABCO shall make (to the extent it can
truthfully do so) the representations of WABCO contained in a certificate of
WABCO (the "WABCO Tax Certificate") substantially to the effect of the WABCO Tax
Certificate contained in the WABCO Disclosure Letter.

     (b) Each of WABCO and MotivePower agrees to take, together with their
respective accountants, all actions reasonably necessary in order to obtain a
favorable determination (if required) from the SEC that the Merger may be
accounted for as a pooling of interests in accordance with generally accepted
accounting principles.

     SECTION 5.9. COMFORT LETTERS. (a) WABCO shall use its reasonable best
efforts to cause to be delivered to MotivePower "comfort" letters of Arthur
Andersen LLP, WABCO's independent public accountants, dated the date on which
the Registration Statement shall become effective and as of the Effective Time,
and addressed to WABCO and MotivePower, in form and substance reasonably
satisfactory to MotivePower and reasonably customary in scope and substance for
letters delivered by independent public accountants in connection with
transactions such as those contemplated by this Agreement.

     (b) MotivePower shall use its reasonable best efforts to cause to be
delivered to WABCO "comfort" letters of Deloitte & Touche LLP, MotivePower's
independent public accountants, dated the date on which the Registration
Statement shall become effective and as of the Effective Time, and addressed to
WABCO and MotivePower, in form and substance reasonably satisfactory to WABCO
and reasonably customary in scope and substance for letters delivered by
independent public accountants in connection with transactions such as those
contemplated by this Agreement.

     SECTION 5.10. COMPLIANCE WITH THE SECURITIES ACT AND POOLING OF INTERESTS
RESTRICTIONS; REGISTRATION RIGHTS; TERMINATION OF VOTING TRUST AND STOCKHOLDERS
AGREEMENT. (a) Within 10 business days after the date hereof, WABCO shall cause
to be prepared and delivered to MotivePower a list (reasonably satisfactory to
counsel for MotivePower) identifying all persons who may be, at the time of the
WABCO Stockholders Meeting, deemed to be "affiliates" of WABCO as that term is
used in paragraphs (c) and (d) of Rule 145 under the Securities Act (the "Rule
145 Affiliates"). WABCO shall use its reasonable best efforts to cause each
person who is identified as a Rule 145 Affiliate in such list to deliver to
MotivePower within 30 days of the date hereof a written agreement in
substantially the form of Exhibit 5.10(a) hereto, executed by each of such
persons identified in the foregoing list. MotivePower shall publish, in a manner
that satisfies the "publication" requirements under applicable SEC rules or
accounting releases, financial results (including combined sales and net income)
covering at least 30 days of post-Merger operations no later than 15 days
following the first month-end that is more than 30 days after the Effective
Date.

     (b) Within 10 business days after the date hereof, MotivePower shall
deliver to WABCO a list (reasonably satisfactory to counsel for WABCO)
identifying those persons who may be, at the time of the MotivePower
Shareholders Meeting, affiliates of MotivePower under applicable SEC accounting
releases with respect to pooling of interests accounting treatment. MotivePower
shall use its reasonable best efforts to enter into a written agreement in
substantially the form of Exhibit 5.10(b) hereto within 30 days of the date
hereof with each of such persons identified in the foregoing list.

     (c) MotivePower acknowledges and agrees that the Common Stock Registration
Rights Agreement, dated as of March 5, 1997, as amended March 28, 1997 (the
"Registration Rights Agreement"), among WABCO, Harvard Private Capital Holdings,
Inc. ("Harvard"), American Industrial Partners Capital Fund II, L.P. ("AIP"),
the Voting Trust created under the Second Amended WABCO Voting Trust/Disposition
Agreement, dated as of December 13, 1995 (the "Voting Trust"), Vestar Equity
Partners, L.P. ("Vestar"), Vestar Capital Partners, Inc., Emilio A. Fernandez,
Jr. and Emilio A. Fernandez, Jr., as custodian for Eric A. Fernandez and Ofelia
B. Fernandez, upon the Effective Time, will be binding upon the Surviving
Corporation as successor to WABCO as though the Surviving Corporation was a
party thereto and the Surviving Corporation hereby agrees to perform all of the
duties and covenants of WABCO ascribed therein, subject to the terms and
                                      -34-
   140

conditions thereof. MotivePower agrees that any references to "Common Stock" in
the Registration Rights Agreement shall be references to MotivePower Common
Stock.

     (d) Prior to the Effective Time, WABCO shall cause the Voting Trust and the
Amended and Restated Stockholders Agreement, dated as of March 5, 1997, among
the Voting Trust, Vestar, Harvard, AIP and WABCO to be terminated.

     SECTION 5.11. LISTING OR QUOTATION OF STOCK. MotivePower shall use its
reasonable best efforts to cause the shares of MotivePower Common Stock to be
issued in the Merger to be approved for listing on the NYSE on or prior to the
Closing Date, subject to official notice of issuance.

     SECTION 5.12. INDEMNIFICATION OF DIRECTORS AND OFFICERS. (a) After the
Effective Time, the Surviving Corporation shall, to the same extent and on the
same terms and conditions provided for in the WABCO Certificate of Incorporation
and the WABCO By-Laws, in each case as of the date of this Agreement, to the
extent consistent with applicable law, indemnify and hold harmless, each present
and former director or officer of WABCO and each Subsidiary of WABCO
(collectively, the "Indemnified Parties") against all costs and expenses
(including reasonable attorneys' fees), judgments, fines, losses, claims,
damages, liabilities and settlement amounts paid in connection with any claim,
action, suit, proceeding or investigation (whether arising before or after the
Effective Time), whether civil, administrative or investigative, arising out of
or pertaining to any action or omission in their capacity as an officer or
director, in each case occurring before the Effective Time (including the
transactions contemplated by this Agreement).

     (b) For a period of six years from the Effective Time, the Surviving
Corporation shall provide to WABCO's current directors and officers liability
insurance protection substantially equivalent in kind and scope as that provided
by WABCO's current directors' and officers' liability insurance policies (copies
of which have been made available to MotivePower); provided, however, that in no
event shall the Surviving Corporation be required to expend in any one year an
amount in excess of 150% of the annual premiums currently paid by WABCO for such
insurance; provided, further, that if during such period the annual premiums for
such comparable insurance coverage exceed such amount, the Surviving Corporation
shall be obligated to provide a policy which, in the reasonable judgment of the
Surviving Corporation, provides the best coverage available for a cost not
exceeding such amount.

     SECTION 5.13. WABCO STOCK OPTIONS. At the Effective Time, each WABCO Stock
Option, vested or unvested, which is outstanding immediately prior to the
Effective Time pursuant to the WABCO Stock Plans in effect on the date hereof
shall become and represent an option to purchase the number of shares of
MotivePower Common Stock (a "Substitute Option") (decreased to the nearest full
share) determined by multiplying (i) the number of shares of WABCO Common Stock
subject to such WABCO Stock Option immediately prior to the Effective Time by
(ii) the Exchange Ratio, at an exercise price per share of MotivePower Common
Stock (rounded up to the nearest cent), equal to the exercise price per share of
WABCO Common Stock immediately prior to the Effective Time divided by the
Exchange Ratio. It is the intention of the parties that the above formula shall
be applied in a manner consistent with Section 424(a) of the Code. MotivePower
shall pay cash to holders of WABCO Stock Options in lieu of issuing fractional
shares of MotivePower Common Stock upon the exercise of Substitute Options for
shares of MotivePower Common Stock, unless in the judgment of MotivePower such
payment would adversely affect the ability to account for the Merger under the
pooling of interests method. After the Effective Time, except as provided above
in this Section 5.13, each Substitute Option shall be exercisable upon the same
terms and conditions as were applicable under the related WABCO Stock Option
immediately prior to the Effective Time. MotivePower shall take all corporate
action necessary to reserve for issuance a sufficient number of shares of
MotivePower Common Stock for delivery upon exercise of WABCO Stock Options.
Promptly following the Effective Time of the Merger, MotivePower shall file a
registration statement on Form S-8 or another appropriate form with respect to
the shares of MotivePower Common Stock subject to such options and shall use its
reasonable best efforts to maintain the effectiveness of such registration
statement or registration statements (and maintain the current status of the
prospectus or prospectuses contained therein) for so long as such options remain
outstanding. With respect to those individuals who subsequent to the Merger will
be subject to the reporting requirements under Section 16(a) of the Exchange
Act, where applicable,

                                      -35-
   141

MotivePower shall administer WABCO Option Plans in a manner that complies with
Rule 16b-3 promulgated under the Exchange Act to the extent WABCO Option Plans
complied with such rule prior to the Merger. WABCO and MotivePower shall take
all necessary action to implement or to provide for the implementation of the
provisions of this Section 5.13.

     SECTION 5.14. WABCO EMPLOYEE STOCK PURCHASE PLAN. WABCO agrees to take any
and all action necessary pursuant to the terms of the ESPP to terminate such
plan on June 30, 1999.

     SECTION 5.15. BENEFIT PLANS TO BE HONORED. (a) From and after the Effective
Time, MotivePower shall honor and shall cause the WABCO Subsidiaries to honor
all MotivePower Plans, all WABCO Plans and all employment agreements entered
into by MotivePower or WABCO (or their Subsidiaries) prior to the date hereof;
provided, however, that nothing in this Agreement shall be interpreted as
limiting the power of MotivePower or the WABCO Subsidiaries to amend or
terminate any WABCO Plan or any other individual employee benefit plan, program,
agreement or policy or as requiring MotivePower to offer to continue (other than
as required by its terms) any written employment contract.

     (b) All individuals who are employees of WABCO or a WABCO Subsidiary at the
Effective Time (the "Affected Employees") shall be given credit for all service
with WABCO and its Subsidiaries (or service credited by WABCO or such
Subsidiaries) under all employee benefit plans and arrangements currently
maintained by MotivePower or any of its Subsidiaries in which they become
participants for purposes of eligibility, vesting, level of participant
contribution and benefit accruals (except benefit accruals under defined benefit
pension plans) to the same extent as if rendered to MotivePower or any of its
Subsidiaries. MotivePower shall cause to be waived any pre-existing condition
limitation under its welfare plans that might otherwise apply to an Affected
Employee who may become covered by such plans. MotivePower agrees to recognize
(or cause to be recognized) the dollar amount of all expenses incurred by
Affected Employees during the calendar year in which the Effective Time occurs
for purposes of satisfying the calendar year deductions and co-payment
limitations for such year under the relevant benefit plans of MotivePower and
its Subsidiaries that may cover such employees.

     SECTION 5.16. STATE TAKEOVER LAWS. If any "fair price," "business
combination" or "control share acquisition" statute or other similar statute or
regulation shall become applicable to the transactions contemplated hereby, the
WABCO Option Agreement or the MotivePower Option Agreement, WABCO and
MotivePower and their respective Boards of Directors shall use their reasonable
best efforts to grant such approvals and take such actions as are necessary so
that the transactions contemplated hereby and thereby may be consummated as
promptly as practicable on the terms contemplated hereby and thereby and
otherwise act to minimize the effects of any such statute or regulation on the
transactions contemplated hereby and thereby.

     SECTION 5.17. TRANSFER TAXES. WABCO or, after the Effective Time, the
Surviving Corporation on behalf of WABCO, shall pay or cause to be paid any real
property transfer, gains or similar taxes imposed as a result of the Merger.

                                   ARTICLE VI

been approved and adopted by the stockholders of WABCO, and (ii) this Agreement
and the Merger shall have been approved and adopted by the shareholders of
MotivePower.

     (b) Waiting Periods; Approvals. The waiting period applicable to the
consummation of the Merger under the HSR Act shall have expired or been
terminated and any other approvals required under applicable analogous foreign

additional conditions, any of which may be waived in writing exclusively by
MotivePower:

     (a) Representations and Warranties. The representations and warranties of
WABCO set forth in this Agreement that are qualified as to materiality shall be
true and correct as of the Closing Date and the representations and warranties
that are not so qualified, taken together, shall be true and correct in all

an earlier date); and MotivePower shall have received a certificate signed on
behalf of WABCO by an executive officer of WABCO to such effect.

     (b) Performance of Obligations. WABCO shall have performed in all material

WABCO to such effect.

     (c) Tax Opinion. MotivePower shall have received an opinion of Sidley &
Austin, in form and substance reasonably satisfactory to MotivePower, dated the
Effective Time, substantially to the effect that on the basis of facts,
representations and assumptions set forth in such opinion which are consistent
with the state of facts existing as of the Effective Time, for federal income
tax purposes:

          (i) the Merger will constitute a "reorganization" within the meaning
     of Section 368(a) of the Code, and WABCO and MotivePower will each be a
     party to that reorganization within the meaning of Section 368(b) of the
     Code;

          (ii) no gain or loss will be recognized by MotivePower or WABCO as a

     Stock;

     WABCO Common Stock;

          (v) the holding period for shares of MotivePower Common Stock received
     in exchange for shares of WABCO Common Stock pursuant to the Merger will
     include the holder's holding period for such shares of WABCO Common Stock,
     provided such shares of WABCO Common Stock were held as capital assets by
     the holder at the Effective Time; and

                                      -37-
   143

          (vi) a stockholder of WABCO who receives cash in lieu of a fractional
     share of MotivePower Common Stock will recognize gain or loss equal to the
     difference, if any, between such stockholder's basis in the fractional
     share (determined under clause (iv) above) and the amount of cash received.

In rendering such opinion, Sidley & Austin may rely as to matters of fact upon
the representations contained herein and may receive and rely upon
representations from MotivePower, WABCO, and others, including representations
from MotivePower to the effect of the representations in the MotivePower Tax

behalf of MotivePower by an executive officer of MotivePower to such effect.

     (b) Performance of Obligations. MotivePower shall have performed in all
material respects each obligation and agreement and shall have complied in all
material respects with each covenant required to be performed or complied with
by it under this Agreement at or prior to the Effective Time; and WABCO shall
have received a certificate signed on behalf of MotivePower by an executive
officer of MotivePower to such effect.

     (c) Tax Opinion. WABCO shall have received an opinion of Kirkland & Ellis,
in form and substance reasonably satisfactory to WABCO, dated the Effective
Time, substantially to the effect that on the basis of facts, representations
and assumptions set forth in such opinion which are consistent with the state of
facts existing as of the Effective Time, for federal income tax purposes:

     cash is paid) will be the same as the aggregate tax basis of such shares of
     WABCO Common Stock;

          (v) the holding period for shares of MotivePower Common Stock received

     the holder at the Effective Time; and

          (vi) a stockholder of WABCO who receives cash in lieu of a fractional
     share of MotivePower Common Stock will recognize gain or loss equal to the
     difference, if any, between such stockholder's basis in the fractional
     share (determined under clause (iv) above) and the amount of cash received.

In rendering such opinion, Kirkland & Ellis may rely as to matters of fact upon

written notice by the terminating party to the other party), whether before or
after approval of the matters presented in connection with the Merger by the
shareholders of MotivePower or the stockholders of WABCO:

     (a) by mutual written consent of MotivePower and WABCO; or

     (b) by either MotivePower or WABCO, if the Merger shall not have been
consummated by November 30, 1999 (the "End Date"); provided, however, that the
right to terminate this Agreement under this Section 7.1(b) shall not be
available to any party whose failure to fulfill any obligation under this
Agreement has been the cause of or resulted in the failure of the Merger to
occur on or before the End Date; or

     (c) by either MotivePower or WABCO, if a court of competent jurisdiction or
other Governmental Entity shall have issued a final, non-appealable order,
decree or ruling, or taken any other action, having the effect of permanently
restraining, enjoining or otherwise prohibiting the Merger; or

     (d) by either MotivePower or WABCO (i) if, at the WABCO Stockholders
Meeting (including any adjournment or postponement thereof), the requisite vote
of the stockholders of WABCO in favor of adoption of this Agreement shall not
have been obtained or (ii) if, at the MotivePower Shareholders Meeting
(including any adjournment or postponement thereof), the requisite vote of the
shareholders of MotivePower in favor of adoption of this Agreement shall not
have been obtained; or

and knowingly breached the covenant contained in Section 5.1; or

     (g) by WABCO or MotivePower at any time on or prior to the 45th day after
the date hereof, if the Board of Directors of MotivePower shall have determined

written agreement concerning such Takeover Proposal after determining, pursuant
to Section 5.1, that such Takeover Proposal constitutes a Superior Proposal;
provided, however, that MotivePower may not terminate this Agreement pursuant to
this Section 7.1(g) unless (i) MotivePower has delivered to WABCO a written
notice of MotivePower's intent to enter into such an agreement to effect the
Superior Proposal, attaching the most current version of such agreement to such
notice (which version shall be updated on a current basis), (ii) five business
days have elapsed following delivery to WABCO of such written notice by
MotivePower and (iii) during such five business day-period MotivePower has fully
cooperated with WABCO, including informing WABCO (to the extent not otherwise
done so pursuant to clause (i) or Section 5.1(b)) of the terms and conditions of
the Takeover Proposal, with the intent of enabling WABCO to agree to a
modification of the terms and conditions of this Agreement so that the
transactions contemplated hereby may be effected; provided, further, that
MotivePower may not terminate this Agreement pursuant to this Section 7.1(g)
unless at the end of such five business day-period the Board of Directors of
MotivePower continues reasonably to believe that the Takeover Proposal
constitutes a Superior Proposal and prior to such termination MotivePower pays
to WABCO the amounts specified under Section 7.3(d); or

     (h) by MotivePower, if a material breach of or failure to perform any
representation, warranty, covenant or agreement on the part of WABCO set forth
in this Agreement shall have occurred which would cause the conditions set forth
in Sections 6.2(a) or 6.2(b) not to be satisfied, and such conditions are
incapable of being satisfied by the End Date; or

                                      -39-
   145

     (i) by MotivePower, if the Board of Directors of WABCO shall not have
recommended or shall have modified in a manner materially adverse to MotivePower

the date hereof, if the Board of Directors of WABCO shall have determined to
recommend a Takeover Proposal to its stockholders and to enter into a binding
written agreement concerning such Takeover Proposal after determining, pursuant
to Section 5.1, that such Takeover Proposal constitutes a Superior Proposal;
provided, however, that WABCO may not terminate this Agreement pursuant to this
Section 7.1(k) unless (i) WABCO has delivered to MotivePower a written notice of
WABCO's intent to enter into such an agreement to effect the Superior Proposal,
attaching the most current version of such agreement to such notice (which
version shall be updated on a current basis), (ii) five business days have
elapsed following delivery to MotivePower of such written notice by WABCO and
(iii) during such five business day-period WABCO has fully cooperated with
MotivePower, including informing MotivePower (to the extent not otherwise done

Takeover Proposal and the identity of the Person making the Takeover Proposal,
with the intent of enabling MotivePower to agree to a modification of the terms
and conditions of this Agreement so that the transactions contemplated hereby
may be effected; provided, further, that WABCO may not terminate this Agreement
pursuant to this Section 7.1(k) unless at the end of such five business
day-period the Board of Directors of WABCO continues reasonably to believe that
the Takeover Proposal constitutes a Superior Proposal and prior to such
termination WABCO pays to MotivePower the amounts specified under Section
7.3(b); or

     (l) by WABCO, if a material breach of or failure to perform any
representation, warranty, covenant or agreement on the part of MotivePower set

incapable of being satisfied by the End Date.

     SECTION 7.2. EFFECT OF TERMINATION. In the event of termination of this

stockholders or Affiliates, except as set forth in Section 7.3 and except to the
extent that such termination results from the willful breach by a party of any
of its representations, warranties, covenants or agreements contained in this
Agreement; provided, however, that the provisions of Sections 7.3, 8.2 and 8.7

                             STOCKHOLDERS' MEETINGS

     1. Time and Place of Meetings. All meetings of the shareholders for the
election of Directors or for any other purpose will be held at such time and
place, within or without the Commonwealth of Pennsylvania, as may be designated
by the Board or, in the absence of a designation by the Board, the Chairman, the
Chief Executive Officer, or the Secretary, and stated in the notice of meeting.
The Board may postpone and reschedule any previously scheduled annual or special
meeting of the shareholders.

     2. Annual Meeting. An annual meeting of the shareholders will be held at
such date and time as may be designated from time to time by the Board, at which
meeting the shareholders will elect by a plurality vote the Directors to succeed
those whose terms expire at such meeting and will transact such other business
as may properly be brought before the meeting in accordance with By-Law 8.

     3. Special Meetings. Special meetings of the shareholders may be called
only by (i) the Chairman or (ii) the Secretary within 10 calendar days after
receipt of the written request of a majority of the Whole Board. Any such
request by a majority of the Whole Board must be sent to the Chairman and the
Secretary and must state the purpose or purposes of the proposed meeting.
Special meetings of holders of the outstanding Preferred Stock, if any, may be
called in the manner and for the purposes provided in the applicable Preferred
Stock Designation. For purposes of these By-Laws, "Whole Board" shall mean the
total number of Directors provided for in By-Law 10(a), which number shall
include any vacancies.

     4. Notice of Meetings. Written notice of every meeting of the shareholders,
stating the place, date, and hour of the meeting and, in the case of a special
meeting, the purpose or purposes for which the meeting is called, will be given
not less than 10 nor more than 60 calendar days before the date of the meeting
to each shareholder of record entitled to vote at such meeting, except as
otherwise provided herein or by law. When a meeting is adjourned to another
place, date, or time, written notice need not be given of the adjourned meeting
if the place, date, and time thereof are announced at the meeting at which the
adjournment is taken; provided, however, that if the adjournment is for more
than 30 calendar days, or if after the adjournment a new record date is fixed
for the adjourned meeting, written notice of the place, date, and time of the
adjourned meeting must be given in conformity herewith. At any adjourned
meeting, any business may be transacted which properly could have been
transacted at the original meeting.

     5. Inspectors. The Board may appoint one or more inspectors of election to
act as judges of the voting and to determine those entitled to vote at any
meeting of the shareholders, or any adjournment thereof, in advance of such
meeting. The Board may designate one or more persons as alternate inspectors to
replace any inspector who fails to act. If no inspector or alternate is able to
act at a meeting of shareholders, the presiding officer of the meeting may
appoint one or more substitute inspectors.

     6. Quorum. Except as otherwise provided by law or in a Preferred Stock
Designation, the holders of a majority of the stock issued and outstanding and
entitled to vote thereat, present in person or represented by proxy, will
constitute a quorum at all meetings of the shareholders for the transaction of
business thereat. If, however, such quorum is not present or represented at any
meeting of the shareholders, the shareholders entitled to vote thereat, present
in person or represented by proxy, will have the power to adjourn the meeting
from time to time, without notice other than announcement at the meeting, until
a quorum is present or represented.

     7. Voting. Except as otherwise provided by law, by the Articles of
Incorporation, or in a Preferred Stock Designation, each shareholder will be
entitled at every meeting of the shareholders to one vote for each share of
stock having voting power standing in the name of such shareholder on the books
of the Company on the record date for the meeting and such votes may be cast
either in person or by written proxy. Every proxy must be duly executed and
filed with the Secretary. A shareholder may revoke any proxy that is not
irrevocable by attending the meeting and voting in person or by filing an
instrument in writing revoking the
   152

proxy or another duly executed proxy bearing a later date with the Secretary.
The vote upon any question brought before a meeting of the shareholders may be
by voice vote, unless otherwise required by the Articles of Incorporation or
these By-Laws or unless the Chairman or the holders of a majority of the
outstanding shares of all classes of stock entitled to vote thereon present in
person or by proxy at such meeting otherwise determine. Every vote taken by
written ballot will be counted by the inspectors of election. When a quorum is
present at any meeting, the affirmative vote of the holders of a majority of the
stock present in person or represented by proxy at the meeting and entitled to
vote on the subject matter and which has actually been voted will be the act of
the shareholders, except in the election of Directors or as otherwise provided
in these By-Laws, the Articles of Incorporation, a Preferred Stock Designation,
or by law.

     8. Order of Business. (a) The Chairman or such other officer of the Company
designated by a majority of the Whole Board will call meetings of the
shareholders to order and will act as presiding officer thereof. Unless
otherwise determined by the Board prior to the meeting, the presiding officer of
the meeting of the shareholders will also determine the order of business and
have the authority in his or her sole discretion to regulate the conduct of any
such meeting, including without limitation by imposing restrictions on the
persons (other than shareholders of the Company or their duly appointed proxies)
who may attend any such shareholders' meeting, by ascertaining whether any
shareholder or his proxy may be excluded from any meeting of the shareholders
based upon any determination by the presiding officer, in his or her sole
discretion, that any such person has unduly disrupted or is likely to disrupt
the proceedings thereat, and by determining the circumstances in which any
person may make a statement or ask questions at any meeting of the shareholders.

     (b) At any annual meeting of the shareholders, only such business will be

meeting (A) a description in reasonable detail of the business desired to be

made in such business. A shareholder must also comply with all applicable
requirements of the Securities Exchange Act of 1934, as amended, and the rules
and regulations thereunder with respect to the matters set forth in this By-Law
8(c). For purposes of this By-Law 8(c) and By-Law 13, "public announcement"
means disclosure in a press release reported by the Dow Jones News Service,
Associated Press, or comparable national news service or in a document publicly
filed by the Company with the Securities and Exchange Commission pursuant to
Sections 13, 14, or 15(d) of the Securities Exchange Act of 1934, as amended, or
furnished to shareholders. Nothing in this By-Law 8(c) will be deemed to affect
any rights of shareholders to request

                                       -2-
   153

inclusion of proposals in the Company's proxy statement pursuant to Rule 14a-8
under the Securities Exchange Act of 1934, as amended.

     (d) At a special meeting of shareholders, only such business may be
conducted or considered as is properly brought before the meeting. To be
properly brought before a special meeting, business must be (i) specified in the
notice of the meeting (or any supplement thereto) given by or at the direction
of the Chairman or a majority of the Whole Board in accordance with By-Law 4 or
(ii) otherwise properly brought before the meeting by the presiding officer or
by or at the direction of a majority of the Whole Board.

     (e) The determination of whether any business sought to be brought before
any annual or special meeting of the shareholders is properly brought before
such meeting in accordance with this By-Law 8 will be made by the presiding
officer of such meeting. If the presiding officer determines that any business
is not properly brought before such meeting, he or she will so declare to the
meeting and any such business will not be conducted or considered.

By-Law 10 may be amended to reduce the number of Directors, and upon a vote of
at least 66 2/3% of the Whole Board this By-Law 10 may be amended to increase
the number of Directors, in each case, within the minimum and maximum number of
Directors provided by the Articles of Incorporation. The Directors, other than
those who may be elected by the holders of any series of the Preferred Stock,
will be classified with respect to the time for which they severally hold office
in accordance with the Articles of Incorporation.

     (b) Notwithstanding anything contained in the Articles of Incorporation or
these By-Laws to the contrary, the term of any Director who is also an officer
of the Company will terminate automatically, without any further action on the
part of the Board or such Director, upon the termination for any reason of such
Director in his or her capacity as an officer of the Company; provided, however,
that nothing herein shall limit the power of the Nominating Committee to
recommend to the Board that such person serve as a Director, including the
ability to again recommend to the Board that such person fill the vacancy on the
Board resulting from such person's termination as an officer of the Company.
Notwithstanding anything contained in the Articles of Incorporation or these
By-Laws to the contrary, the affirmative vote of at least 66 2/3% of the
Directors then in office will be required to amend, repeal, or adopt any
provision inconsistent with this By-Law 10(b).

     11. Vacancies and Newly Created Directorships. Subject to the rights, if
any, of the holders of any series of Preferred Stock to elect additional
Directors under circumstances specified in a Preferred Stock Designation, newly
created directorships resulting from any increase in the number of Directors and
any vacancies on the Board resulting from death, resignation, disqualification,

effected by a resolution of a majority of the Whole Board, one or more such
vacancies or newly created directorships may be filled by the shareholders at a
meeting of the shareholders called by the Board of Directors. Any Director
elected in accordance with the preceding sentence will hold office for the
remainder of the full term of the class of Directors in which the new
directorship was created or the vacancy occurred and until such Director's
successor is elected and qualified. No decrease in the number of Directors
constituting the Board will shorten the term of an incumbent Director.

     12. Removal. Subject to the rights, if any, of the holders of any series of
Preferred Stock to elect additional Directors under circumstances specified in a
Preferred Stock Designation, any Director may be

                                       -3-

record at the time of giving of notice provided for in this By-Law 13, who is
entitled to vote for the election of Directors at such meeting, and who complies

and (D) any other person or persons (naming such person or persons) pursuant to
which the nomination or nominations are to be made by the shareholder giving the
notice; (v) such other information regarding each nominee proposed by the
shareholder giving the notice as would be required to be included in a proxy
statement filed pursuant to the proxy rules of the Securities and Exchange
Commission had the nominee been nominated, or intended to be nominated, by the
Board; and (vi) the signed consent of each nominee to serve as a Director of the
Company if so elected. At the request of the Board, any person nominated by the
Board for election as a Director must furnish to the Secretary that information
required to be set forth in a shareholder's notice of nomination which pertains
to the nominee. The presiding officer of any annual meeting will, if the facts
warrant, determine that a nomination was not made in accordance with the
procedures prescribed by this By-Law 13, and if he or she should so determine,
he or she will so declare to the meeting and the defective nomination will be
disregarded. A shareholder must also comply with all applicable requirements of
the Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder with respect to the matters set forth in this By-Law 13.

     (f) The Board shall have a Compensation Committee (the "Compensation
Committee") consisting of three members of the Board. At the Effective Time, the
members of the Compensation Committee shall be James V. Napier, Emilio A.
Fernandez and [a MotivePower Director]. These individuals shall serve as members
of the Compensation Committee so long as they remain Directors of the Company.
If there shall be any vacancy on the Compensation Committee, the remaining
members of the Compensation Committee shall select a Director to fill the
vacancy from among the other Directors of the Board. If there shall be a
Deadlock in the determination of filling the vacancy, the Chairman of the
Compensation Committee shall have the authority to resolve the Deadlock. If
there are no remaining members of the Compensation Committee, the Board, by the
affirmative vote of a majority of the Whole Board, shall select Directors to
fill the vacancies from among the Directors of the Board. If there shall be a
Deadlock of the Board in the determination of filling any vacancy, the Executive
Committee shall have the authority to resolve the Deadlock. At the Effective
Time, the Chairman of the Compensation Committee shall be James V. Napier. The
Chairman of the Compensation Committee shall have exclusive authority to
designate an alternate Chairman in the event that the Chairman cannot attend
meetings or ceases to be a member of the Compensation Committee; provided that
the Chairman of the Compensation Committee may change the alternate Chairman at
any time. If at the time the Chairman of the Compensation Committee ceases to be
Chairman and an alternate Chairman has not been designated, then the Board, by
the affirmative vote of a majority of the Whole Board, shall select from the
members of the Compensation Committee, the person to be Chairman. If there shall
be a Deadlock of the Board in the determination of Chairman, the Executive
Committee shall have the authority to resolve the Deadlock. The Compensation
Committee shall have the sole authority to establish the
                                       -7-

compensation for, and the reimbursement of the expenses of, Directors for
membership on the Board and on Committees, attendance at meetings of the Board
or Committees of the Board, and for other services by Directors to the Company,
of all officers and agents of the Company who are also Directors of the Company.
The Compensation Committee shall determine the compensation of senior management
and the personnel of the Company based upon the recommendations of the Chief
Executive Officer, and shall establish on an annual basis the compensation of
the Chairman of the Board and the Chief Executive Officer, subject in each case
to the discretion of the Board of Directors upon a vote of a majority of the
Whole Board to change or modify such actions. In addition, the Compensation
Committee shall have the authority to administer the existing options and
benefits plans of the Company. The Compensation Committee shall have the
exclusive authority to resolve any Deadlock of the Board regarding the
termination, replacement of, or any other matter regarding the Chief Executive
Officer.

     (g) The Board, by resolution passed by a majority of the Whole Board, may
designate one or more additional Committees, each such Committee to consist of
one or more Directors and each to have such lawfully delegable powers and duties
as the Board may confer.

     (h) The Executive Committee, the Nominating Committee, the Audit Committee,
the Operations Committee, the Compensation Committee and each other Committee of
the Board will serve as provided in these By-Laws or if not provided herein at
the pleasure of the Board or as may be specified in any resolution from time to
time adopted by the Board. The majority of the Committee may designate one or
more Directors as alternate members of any such Committee, who may replace any
absent or disqualified member at any meeting of such Committee. In the event of
a Deadlock of the Committee in the determination of who may replace the absent
or disqualified member at any meeting, the Chairman of the Committee shall
resolve the Deadlock.

     (i) Except as otherwise provided in these By-Laws or by law, any Committee
of the Board, to the extent provided in By-Law 19(a), (c), (d), (e), (f) or, if
applicable, in the resolution of the Board, will have and may exercise all the
powers and authority of the Board in the direction of the management of the
business and affairs of the Company. Any such Committee designated by the Board
will have such name as may be determined from time to time by resolution adopted
by the Board. Unless otherwise prescribed by the Board or these By-Laws, a
majority of the members of any Committee of the Board will constitute a quorum
for the transaction of business, and the act of a majority of the members
present at a meeting at which there is a quorum will be the act of such
Committee. In the event of a Deadlock of the Committee, the Chairman of the
Committee shall resolve the conflict. If the Chairman is not present to resolve
the conflict, no action may be taken by the Committee. To the extent not
provided in these By-Laws, each Committee of the Board may prescribe its own
rules for calling and holding meetings and its method of procedure, subject to
any rules prescribed by the Board, and will keep a written record of all actions
taken by it.

     (j) By-Law 19 shall terminate immediately after the conclusion of the
annual meeting of shareholders of the Company in the year 2002, at which time
the following By-Law 19 shall be effective:

     "19. Committees. (a) The Board, by resolution passed by a majority of the
Whole Board, will designate an executive and finance committee ("Executive and
Finance Committee") of not less than three members of the Board, one of whom
will be the Chairman. The Executive and Finance Committee will have and may
exercise the powers of the Board, except the power to amend these By-Laws or the
Articles of Incorporation (except, to the extent authorized by a resolution of
the Whole Board, to fix the designation, preferences, and other terms of any
series of Preferred Stock), adopt an agreement of merger or consolidation,
authorize the issuance of stock, declare a dividend, or recommend to the
shareholders the sale, lease, or exchange of all or substantially all of the
Company's property and assets, a dissolution of the Company, or a revocation of
a dissolution, and except an otherwise provided by law.

     (b) The Board, by resolution passed by a majority of the Whole Board, may
designate one or more additional committees, each such committee to consist of
one or more Directors and each to have such lawfully delegable powers and duties
as the Board may confer.

                                       -8-
   159

     (c) The Executive and Finance Committee and each other committee of the
Board will serve at the pleasure of the Board or as may be specified in any
resolution from time to time adopted by the Board. The Board may designate one
or more Directors as alternate members of any such committee, who may replace
any absent or disqualified member at any meeting of such committee. In lieu of
such action by the Board, in the absence or disqualification of any member of a
committee of the Board, the members thereof present at any such meeting of such
committee and not disqualified from voting, whether or not they constitute a
quorum, may unanimously appoint another member of the Board to act at the
meeting in the place of any such absent or disqualified member.

     (d) Except as otherwise provided in these By-Laws or by law, any committee
of the Board, to the extent provided in By-Law 19(a) or, if applicable, in the
resolution of the Board, will have and may exercise all the powers and authority
of the Board in the direction of the management of the business and affairs of
the Company. Any such committee designated by the Board will have such name as
may be determined from time to time by resolution adopted by the Board. Unless
otherwise prescribed by the Board, a majority of the members of any committee of
the Board will constitute a quorum for the transaction of business, and the act
of a majority of the members present at a meeting at which there is a quorum
will be the act of such committee. Each committee of the Board may prescribe its
own rules for calling and holding meetings and its method of procedure, subject
to any rules prescribed by the Board, and will keep a written record of all
actions taken by it."

     Nothing contained in this subsection shall preclude the Board or the
shareholders of the Company from amending, modifying or adopting any provision
inconsistent with the provisions of this By-Law 19(j), whether before or after
their effectiveness, in accordance with the terms of these By-Laws, the Articles
of Incorporation and applicable law.

     20. Rules. The Chairman of the Board and Chief Executive Officer shall
jointly establish, or, in the absence of the Chairman of the Board, the Chief
Executive Officer shall establish, an agenda and the order of business of each
meeting of the Board of Directors and shall conduct such meeting; provided,
however, that this shall not preclude any Director from raising any order of
business which may be appropriately raised at such meetings. The Board may adopt
rules and regulations for the conduct of meetings by a vote of the majority of
the Whole Board.

                                    NOTICES

     21. Generally. Except as otherwise provided by law, these By-Laws, or the
Articles of Incorporation, whenever by law or under the provisions of the
Articles of Incorporation or these By-Laws notice in required to be given to any
Director or shareholder, it will not be construed to require personal notice,
but such notice may be given in writing, by mail, addressed to such Director or
shareholder, at the address of such Director or shareholder as it appears on the
records of the Company, with postage thereon prepaid, and such notice will be
deemed to be given at the time when the same is deposited in the United States
mail. Notice to Directors may also be given by telephone, telegram, telex,
facsimile, or similar medium of communication or as otherwise nay be permitted
by these By-Laws.

     22. Waivers. Whenever any notice is required to be given by law or under
the provisions of the Articles of Incorporation or these By-Laws, a waiver
thereof in writing, signed by the person or persons entitled to such notice,
whether before or after the time of the event for which notice is to be given,
will be deemed equivalent to such notice. Attendance of a person at a meeting
will constitute a waiver of notice of such meeting, except when the person
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction, of any business because the meeting is not lawfully
called or convened.

                                    OFFICERS

     23. Generally. The officers of the Company will be elected by the Board and
will consist of a Chairman, a Chief Executive Officer, a President (who may also
be the Chief Operating Officer), a Chief Operating Officer, a Secretary, and a
Treasurer; provided that the Chairman shall have only those powers
                                       -9-
   160

specifically granted to him by a majority of the Whole Board, in any event no
other officer will report directly to the Chairman nor will the Chairman have
the power to appoint or remove any officer. The Chief Executive Officer will
report directly to the Board. The Board of Directors may also choose any or all
of the following: one or more Vice Chairmen (each of which shall possess all the
rights and powers designated by the Board), one or more Assistants to the
Chairman, one or more Vice Presidents (who may be given particular designations
with respect to authority, function, or seniority), and such other officers as
the Board may from time to time determine. Notwithstanding the foregoing, by
specific action the Board may authorize the Chief Executive Officer to appoint
any person to any office other than Chairman, Chief Executive Officer,
President, Secretary, or Treasurer. Any number of offices may be held by the
same person. Any of the offices may be left vacant from time to time as the
Board may determine. In the case of the absence or disability of any officer of
the Company or for any other reason deemed sufficient by a majority of the
Board, the Board, subject to the powers of the Executive Committee to resolve
any Deadlock, may delegate the absent or disabled officer's powers or duties to
any other officer or to any Director.

     24. [INTENTIONALLY OMITTED].

     25. Succession. The officers of the Company will hold office until their
successors are elected and qualified. Any officer may be removed at any time by
the affirmative vote of a majority of the Whole Board. Any vacancy occurring in
any office of the Company may be filled by the Board, subject to the powers of
the Executive Committee to resolve any Deadlock and to the powers of the
Compensation Committee to resolve Deadlock matters regarding the Chief Executive
Officer, as provided in By-Law 23.

     26. Authority and Duties. Each of the officers of the Company will have
such authority and will perform such duties as are customarily incident to their
respective offices or as may be specified from time to time by the Board.

                                     STOCK

     27. Certificates. Certificates representing shares of stock of the Company
will be in such form as is determined by the Board, subject to applicable legal
requirements. Each such certificate will be numbered and its issuance recorded
in the books of the Company, and such certificate will exhibit the holder's name
and the number of shares and will be signed by, or in the name of, the Company
by the Chairman and the Secretary or an Assistant Secretary, or the Treasurer or
an Assistant Treasurer, and will also be signed by, or bear the facsimile
signature of, a duly authorized officer or agent of any properly designated
transfer agent of the Company. Any or all of the signatures and the seal of the
Company, if any, upon such certificates may be facsimiles, engraved, or printed.
Such certificates may be issued and delivered notwithstanding that the person
whose facsimile signature appears thereon may have ceased to be such officer at
the time the certificates are issued and delivered.

     28. Classes of Stock. The designations, preferences, and relative
participating, optional, or other special rights of the various classes of stock
or series thereof, and the qualifications, limitations, or restrictions thereof,
will be set forth in full or summarized on the face or back of the certificates
which the Company issues to represent its stock or, in lieu thereof, such
certificates will set forth the office of the Company from which the holders of
certificates may obtain a copy of such information.

     29. Lost, Stolen, or Destroyed Certificates. The Secretary may direct a new
certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the Company alleged to have been lost,
stolen, or destroyed, upon the making of an affidavit of that fact, satisfactory
to the Secretary, by the person claiming the certificate of stock to be lost,
stolen, or destroyed. As a condition precedent to the issuance of a new
certificate or certificates, the Secretary may require the owners of such lost,
stolen, or destroyed certificate or certificates to give the Company a bond in
such sum and with such surety or sureties as the Secretary may direct as
indemnity against any claims that may be made against the Company with respect
to the certificate alleged to have been lost, stolen, or destroyed or the
issuance of the new certificate.

     30. Record Dates. (a) In order that the Company may determine the
shareholders entitled to notice of or to vote at any meeting of shareholders or
any adjournment thereof, the Board may fix a record date, which
                                      -10-
   161

will not be more than 60 nor less than 10 calendar days before the date of such
meeting. If no record date is fixed by the Board, the record date for
determining shareholders entitled to notice of or to vote at a meeting of
shareholders will be at the close of business on the calendar day next preceding
the day on which notice is given, or, if notice is waived, at the close of
business on the calendar day next preceding the day on which the meeting is
held. A determination of shareholders of record entitled to notice of or to vote
at a meeting of the shareholders will apply to any adjournment of the meeting;
provided, however, that the Board may fix a new record date for the adjourned
meeting.

     (b) In order that the Company may determine the shareholders entitled to
receive payment of any dividend or other distribution or allotment of any rights
or the shareholders entitled to exercise any rights in respect of any change,
conversion, or exchange of stock, or for the purpose of any other lawful action,
the Board may fix a record date, which record date will not be more than 60
calendar days prior to such action. If no record date is fixed, the record date
for determining shareholders for any such purpose will be at the close of
business on the calendar day on which the Board adopts the resolution relating
thereto.

     (c) The Company will be entitled to treat the person in whose name any
share of its stock is registered as the owner thereof for all purposes, and will
not be bound to recognize any equitable or other claim to, or interest in, such
share on the part of any other person, whether or not the Company has notice
thereof, except as expressly provided by applicable law.

                                INDEMNIFICATION

     31. Damages and Expenses. (a) Without limiting the generality or effect of
Article Ninth of the Articles of Incorporation, the Company will go the fullest
extent permitted by applicable law as then in effect indemnify any person (an
"Indemnitee") who is or was involved in any manner (including without limitation
as a party or a witness) or is threatened to be made so involved in any
threatened, pending, or completed investigation, claim, action, suit, or
proceeding, whether civil, criminal, administrative, or investigative (including
without limitation any action, suit, or proceeding by or in the right of the
Company to procure a judgment in its favor) (a "Proceeding") by reason of the
fact that such person is or was or had agreed to become a director, officer,
employee, or agent of the Company, or is or was serving at the request of the
Board or an officer of the Company as a director, officer, employee, or agent of
another corporation, partnership, joint venture, trust, or other enterprise,
whether for profit or not for profit, or anything done or not by such person in
any such capacity, against all expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred by such
person in connection with such proceeding. Such indemnification will be a
contract right and will include the right to receive payment in advance of any
expenses incurred by an Indemnitee in connection with such Proceeding upon
receipt of an undertaking by or on behalf of such person to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the Company as authorized by this By-Law 31 or otherwise.

     (b) The right of indemnification provided in this By-Law 31 will not be
exclusive of any other rights to which any person seeking indemnification may
otherwise be entitled and will be applicable to Proceedings commenced or
continuing after the adoption of this By-Law 31, whether arising from acts or
emissions occurring before or after such adoption.

     (c) The indemnification and advancement of expenses provided by, or granted
pursuant to, this By-Law 31 shall, unless otherwise provided when authorized or
ratified, continue as to a person-who has ceased to be a director, officer,
employee, or agent and shall inure to the benefit of the heirs, executors, and
administrators of such person.

     32. Insurance, Contracts, and Funding. The Company may purchase and
maintain insurance to protect itself and any Indemnitee against any expenses,
judgments, fines, and amounts paid in settlement or incurred by any Indemnitee
in connection with any Proceeding referred to in By-Law 31 or otherwise, to the
fullest extent permitted by applicable law as then in effect. The Company may
enter into contracts with any person entitled to indemnification under By-Law 31
or otherwise, and may create a trust fund, grant a security

                                      -11-
   162

interest, or use other means (including without limitation a letter of credit)
to ensure the payment of such amounts as may be necessary to effect
indemnification as provided in By-Law 31.

                                    GENERAL

     33. Fiscal Year. The fiscal year of the Company will end December 31st of
each year or such other date as may be fixed from time to time by the Board.

     34. Seal. The Board may adopt a corporate seal and use the same by causing
it or a facsimile thereof to be impressed or affixed or reproduced or otherwise.

     35. Reliance upon Books, Reports, and Records. Each Director, each member
of a Committee designated by the Board, and each officer of the Company will, in
the performance of his or her duties, be fully protected in relying in good
faith upon the records of the Company and upon such information, opinions,
reports, or statements presented to the Company by any of the Company's officers
or employees, or Committees of the Board, or by any other person or entity as to
matters the Director, Committee member, or officer believes are within such
other person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Company.

     36. Time Periods. In applying any provision of these By-Laws that requires
that an act be done or not be done a specified number of days prior to an event
or that an act be done during a period of a specified number of days prior to an
event, calendar days will be used unless otherwise specified, the day of the
doing of the act will be excluded, and the day of the event will be included.

     37. Amendments. Except as otherwise provided by law or by the Articles of
Incorporation or these By-Laws, these By-Laws or any of them may be amended in
any respect or repealed at any time, either (i) at any meeting of shareholders,
provided that any amendment or supplement proposed to be acted upon at any such
meeting has been described or referred to in the notice of such meeting, or (ii)
at any meeting of the Board by the affirmative vote of at least 66 2/3% of the
Whole Board until immediately after the conclusion of the annual meeting of
shareholders of the Company in the year 2002 and afterwards, by the majority of
the Whole Board, provided that no amendment adopted by the Board may vary or
conflict with any amendment adopted by the shareholders.

     38. Certain Defined Terms. Terms used herein with initial capital-letters
that are not otherwise defined are used herein as defined in the Articles of
Incorporation.

                FORM OF AFFILIATE LETTER FOR AFFILIATES OF WABCO

MotivePower Industries, Inc.
Two Gateway Center
14th Floor
Pittsburgh, PA 15222

Ladies and Gentlemen:

     I have been advised that as of the date of this letter I may be deemed to
be an "affiliate" of Westinghouse Air Brake Company, a Delaware corporation
("WABCO"), as the term "affiliate" is (i) defined for purposes of paragraphs (c)
and (d) of Rule 145 of the rules and regulations (the "Rules and Regulations")
of the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Act"), and/or (ii) used in and for
purposes of Accounting Series Releases 130 and 135, as amended, of the
Commission. Pursuant to the terms of the Agreement and Plan of Merger dated as
of June 2, 1999 (the "Merger Agreement") between MotivePower Industries, Inc., a
Pennsylvania corporation ("MotivePower"), and WABCO, WABCO will be merged with
and into MotivePower (the "Merger"). Capitalized terms used in this letter
without definition shall have the meanings assigned to them in the Merger
Agreement.

     As a result of the Merger, I may receive shares of Common Stock, par value
$.01 per share, of MotivePower (the "MotivePower Shares") in exchange for shares
of Common Stock, par value $.01 per share, of WABCO (the "WABCO Shares") owned
by me or purchasable upon exercise of stock options.

          1. I represent, warrant and covenant to MotivePower that in the event
     I receive any MotivePower Shares as a result of the Merger:

             A. I shall not make any sale, transfer or other disposition of the
        MotivePower Shares in violation of the Act or the Rules and Regulations.

             B. I have carefully read this letter and the Merger Agreement and
        discussed the requirements of such documents and other applicable
        limitations upon my ability to sell, transfer or otherwise dispose of
        the MotivePower Shares, to the extent I felt necessary, with my counsel
        or counsel for WABCO.

             C. I have been advised that the issuance of the MotivePower Shares
        to me pursuant to the Merger will be registered with the Commission
        under the Act on a Registration Statement on Form S-4. However, I have
        also been advised that, because at the time the Merger is submitted for
        a vote of the stockholders of WABCO, (a) I may be deemed to be an
        affiliate of WABCO and (b) the distribution by me of the MotivePower
        Shares has not been registered under the Act, I may not sell, transfer
        or otherwise dispose of the MotivePower Shares issued to me in the
        Merger unless (i) in the opinion of counsel reasonably satisfactory to
        MotivePower, such sale, transfer or other disposition is made in
        conformity with the volume and other limitations of Rule 145 promulgated
        by the Commission under the Act, (ii) such sale, transfer or other
        disposition has been registered under the Act or (iii) in the opinion of
        counsel reasonably acceptable to MotivePower, such sale, transfer or
        other disposition is otherwise exempt from registration under the Act.

             D. I understand that MotivePower is under no obligation to register
        the sale, transfer or other disposition of the MotivePower Shares by me
        or on my behalf under the Act or, except as provided in paragraph 2(A)
        below, to take any other action necessary in order to make compliance
        with an exemption from such registration available.
   166

             E. I also understand that there will be placed on the certificates
        for the MotivePower Shares issued to me, or any substitutions therefor,
        a legend stating in substance:

           "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
           TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF
           1933 APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE
           TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED
           [          ] [     ], 1999 BETWEEN THE REGISTERED HOLDER HEREOF AND
           MOTIVEPOWER INDUSTRIES, INC., A COPY OF WHICH AGREEMENT IS ON FILE AT
           THE PRINCIPAL OFFICES OF MOTIVEPOWER INDUSTRIES, INC."

             F. I also understand that unless a sale or transfer is made in
        conformity with the provisions of Rule 145, or pursuant to a
        registration statement, MotivePower reserves the right to put the
        following legend on the certificates issued to my transferee:

           "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
           UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO
           RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED
           UNDER THE SECURITIES ACT OF 1933 APPLIES. THE SHARES HAVE BEEN
           ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN
           CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE
           SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE
           TRANSFERRED EXCEPT IN ACCORDANCE WITH AN EXEMPTION FROM THE
           REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933."

             G. I further represent to, and covenant with, MotivePower that I
        will not, during the 30 days prior to the Effective Time (as defined in
        the Merger Agreement), sell, transfer or otherwise dispose of or reduce
        my risk (as contemplated by SEC Accounting Series Release No. 135) with
        respect to WABCO Shares or shares of the capital stock of MotivePower
        that I may hold and, furthermore, that I will not sell, transfer or
        otherwise dispose of or reduce my risk (as contemplated by SEC
        Accounting Series Release No. 135) with respect to the MotivePower
        Shares received by me in the Merger or any other shares of the capital
        stock of MotivePower until after such time as results covering at least
        30 days of combined operations of WABCO and MotivePower have been
        published by MotivePower, in the form of a quarterly earnings report, an
        effective registration statement filed with the Commission, a report to
        the Commission on Form 10-K, 10-Q, or 8-K, or any other public filing or
        announcement which includes the combined results of operations.

             H. Execution of this letter should not be considered an admission
        on my part that I am an "affiliate" of WABCO as described in the first
        paragraph of this letter, nor as a waiver of any rights I may have to
        object to any claim that I am such an affiliate on or after the date of
        this letter.

          2. By MotivePower's acceptance of this letter, MotivePower hereby
        agrees with me as follows:

             A. For so long as and to the extent necessary to permit me to sell
        the MotivePower Shares pursuant to Rule 145 and, to the extent
        applicable, Rule 144 under the Act, MotivePower shall use its reasonable
        best efforts to (i) file, on a timely basis, all reports and data
        required to be filed with the Commission by it pursuant to Section 13 of
        the Securities Exchange Act of 1934, as amended (the "1934 Act"), and
        (ii) furnish to me upon request a written statement as to whether
        MotivePower has complied with such reporting requirements during the 12
        months preceding any proposed sale of the MotivePower Shares by me under
        Rule 145. MotivePower has filed all reports required to be filed with
        the Commission under Section 13 of the 1934 Act during the preceding 12
        months.

             B. It is understood and agreed that the certificates with the
        legends set forth in paragraphs E and F above will be replaced with
        certificates without such legend if (i) one year shall have elapsed from
        the date the undersigned acquired the MotivePower Shares received in the
        Merger and the provisions of Rule 145(d)(2) are then available to the
        undersigned, (ii) two years shall have elapsed
                                       -2-
   167

        from the date the undersigned acquired the MotivePower Shares received
        in the Merger and the provisions of Rule 145(d)(3) are then applicable
        to the undersigned, or (iii) the MotivePower has received either an
        opinion of counsel, which opinion and counsel shall be reasonably
        satisfactory to MotivePower, or a "no action" letter obtained by the
        undersigned from the staff of the Commission, to the effect that the
        restrictions imposed by Rule 145 under the Act no longer apply to the
        undersigned.

                                          Very truly yours,

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

Ladies and Gentlemen:

     I have been advised that as of the date of this letter I may be deemed to
be an "affiliate" of MotivePower Industries, Inc., a Pennsylvania corporation
("MotivePower"), as the term "affiliate" is defined for purposes of Accounting

be merged with and into MotivePower (the "Merger").

     I represent to, and covenant with, MotivePower that I will not, during the

in the form of a quarterly earnings report, an effective registration statement
filed with the Commission, a report to the Commission on Form 10-K, 10-Q, or
8-K, or any other public filing or announcement which includes the combined
results of operations, sell, transfer or otherwise dispose of or reduce my risk
with respect to any shares of the capital stock of MotivePower ("MotivePower
Stock") or WABCO that I may hold.

     Execution of this letter should not be considered an admission on my part

this letter, nor as a waiver of any rights I may have to object to any claim
that I am such an affiliate on or after the date of this letter.

                          WABCO STOCK OPTION AGREEMENT

     STOCK OPTION AGREEMENT dated as of June 2, 1999 (the "Agreement") between
Westinghouse Air Brake Company, a Delaware corporation (the "Grantor"), and
MotivePower Industries, Inc., a Pennsylvania corporation (the "Grantee").

     WHEREAS, the Grantor and the Grantee are entering into an Agreement and
Plan of Merger dated as of the date hereof (the "Merger Agreement"), which
provides, among other things, for the merger of Grantor with and into Grantee
(the "Merger");

     WHEREAS, as a condition and inducement to Grantee's willingness to enter
into the Merger Agreement, the Grantee has requested that the Grantor grant to
the Grantee an option to purchase up to 6,453,710 shares of Common Stock, par
value $0.01 per share, of the Grantor (the "Common Stock"), upon the terms and
subject to the conditions hereof; and

     WHEREAS, in order to induce the Grantee to enter into the Merger Agreement,
the Grantor is willing to grant the Grantee the requested option.

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:

     1. The Option; Exercise; Payment of Spread. (a) Contemporaneously herewith
the Grantee and the Grantor are entering into the Merger Agreement. Subject to
the other terms and conditions set forth herein, the Grantor hereby grants to
the Grantee an irrevocable option (the "Option") to purchase up to 6,453,710
shares of Common Stock (the "Shares") at a cash purchase price equal to $21.6125
per share (the "Purchase Price"). The Option may be exercised by the Grantee, in
whole or in part, at any time, or from time to time, following (but not prior
to) the occurrence of one of the events set forth in Section 3(c) hereof, and
prior to the termination of the Option in accordance with the terms of this
Agreement.

     (b) In the event the Grantee wishes to exercise the Option, the Grantee
shall send a written notice to the Grantor (the "Stock Exercise Notice")
specifying a date (subject to the HSR Act (as defined below) and any other
applicable regulatory approvals) not later than 10 business days and not earlier
than three business days following the date such notice is given for the closing
of such purchase.

     (c) If at any time the Option is then exercisable pursuant to the terms of
Section 1(a) hereof, the Grantee may elect, in lieu of exercising the Option to
purchase Shares provided in Section 1(a) hereof, to send a written notice to the
Grantor (the "Cash Exercise Notice") specifying a date not later than 20
business days and not earlier than 10 business days following the date such
notice is given on which date the Grantor shall pay to the Grantee an amount in
cash equal to the Spread (as hereinafter defined) multiplied by all or such
portion of the Shares subject to the Option as Grantee shall specify. As used
herein, "Spread" shall mean the excess, if any, over the Purchase Price of the
higher (x) if applicable, the highest price per share of Common Stock (including
any brokerage commissions, transfer taxes and soliciting dealers' fees) paid or
proposed to be paid by any person pursuant to any Takeover Proposal (as defined
in the Merger Agreement) (the "Alternative Purchase Price") or (y) the closing
price of the shares of Common Stock on the New York Stock Exchange (the "NYSE")
Composite Tape, the American Stock Exchange (the "AMEX") or The Nasdaq National
Market (the "Nasdaq"), as the case may be, on the last trading day immediately
prior to the date of the Cash Exercise Notice (the "Closing Price"). If the
Alternative Purchase Price includes any property other than cash, the
Alternative Purchase Price shall be the sum of (i) the fixed cash amount, if
any, included in the Alternative Purchase Price plus (ii) the fair market value
of such other property. If such other property consists of securities with an
existing public trading market, the average of the closing prices (or the
average of the closing bid and asked prices if closing prices are unavailable)
for such securities in their principal public trading market on the five trading
days ending five days prior to the date of the Cash Exercise Notice shall be
deemed to equal the fair market value of such property. If such other property
consists of something other than cash or securities with an existing public
trading market and, as of the payment date for the Spread, agreement on the
value of such other property has not been reached, the Alternative Purchase
Price shall be deemed to equal the Closing Price. Upon exercise of its right to
receive cash pursuant to this Section 1(c), the obligations of the Grantor to
deliver Shares pursuant to Section 4 shall
   172

be terminated with respect to such number of Shares for which the Grantee shall
have elected to be paid the Spread.

     2. Adjustments. (a) In the event of any change in the number of issued and
outstanding shares of Common Stock by reason of any stock dividend, stock split,
split-up, recapitalization, merger or other change in the corporate or capital
structure of the Grantor, the number of Shares subject to this Option and the
purchase price per Share shall be appropriately adjusted to restore the Grantee
to its rights hereunder, including its right to purchase Shares representing 19%
of the capital stock of the Grantor entitled to vote generally for the election
of the directors of Grantor which is issued and outstanding immediately prior to
the exercise of the Option.

     (b) Without limiting the parties' relative rights and obligations under the
Merger Agreement, in the event that Grantor enters into an agreement (i) to
consolidate with or merge into any person, other than Grantee or one of its
subsidiaries, and Grantor will not be the continuing or surviving corporation in
such consolidation or merger, (ii) to permit any person, other than Grantee or
one of its subsidiaries, to merge into Grantor, and Grantor will be the
continuing or surviving corporation, but in connection with such merger, the
shares of Common Stock outstanding immediately prior to the consummation of such
merger will be changed into or exchanged for stock or other securities of
Grantor or any other person or cash or any other property, or the shares of
Common Stock outstanding immediately prior to the consummation of such merger
will, after such merger, represent less than 50% of the outstanding voting
securities of the merged company, or (iii) to sell or otherwise transfer all or
substantially all of its assets to any person, other than Grantee or one of its
subsidiaries, then, and in each such case, the agreement governing such
transaction will make proper provision so that the Option will, upon the
consummation of any such transaction and upon the terms and conditions set forth
herein, be converted into, or exchanged for, an option with identical terms
appropriately adjusted to acquire the number and class of shares or other
securities or property that Grantee would have received in respect to Common
Stock if the Option had been exercised immediately prior to such consolidation,
merger, sale, or transfer, or the record date therefor, as applicable and make
any other necessary adjustments.

     3. Conditions to Delivery of Shares. The Grantor's obligation to deliver
Shares upon exercise of the Option is subject only to the conditions that:

     (a) No preliminary or permanent injunction or other order issued by any
federal or state court of competent jurisdiction in the United States
prohibiting the delivery of the Shares shall be in effect; and

     (b) Any applicable waiting periods under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 (the "HSR Act") shall have expired or been terminated;
and

     (c) (i) the Merger Agreement is terminated pursuant to Section 7.1(d)(i)
and either (I) a Takeover Proposal with respect to Grantor shall have been made
after the date of the Merger Agreement and prior to the Grantor Stockholders
Meeting (as defined in the Merger Agreement) or (II) the Board of Directors of
Grantor shall not have recommended or shall have modified in a manner materially
adverse to Grantee its recommendation of the Merger Agreement and Merger; or
(ii) the Merger Agreement is terminated pursuant to Section 7.1(i), 7.1(j) or
7.1(k) of the Merger Agreement.

     4. The Closing. (a) Any closing hereunder shall take place on the date
specified by the Grantee in its Stock Exercise Notice or Cash Exercise Notice,
as the case may be, at 9:00 A.M., local time, at the offices of Doepken Keevican
& Weiss, 58th Floor, USX Tower, 600 Grant Street, Pittsburgh, Pennsylvania, or,
if the conditions set forth in Section 3(a), (b) or (c) have not then been
satisfied, on the second business day following the satisfaction of such
conditions, or at such other time and place as the parties hereto may agree (the
"Closing Date"). On the Closing Date, (i) in the event of a closing pursuant to
Section 1(b) hereof, the Grantor will deliver to the Grantee a certificate or
certificates representing the Shares in the denominations designated by the
Grantee in its Stock Exercise Notice and the Grantee will purchase such Shares
from the Grantor at the price per Share equal to the Purchase Price or (ii) in
the event of a closing pursuant to Section 1(c) hereof, the Grantor will deliver
to the Grantee cash in an amount determined pursuant to

                                       -2-
   173

Section 1(c) hereof. Any payment made pursuant to this Agreement shall be made
by certified or official bank check or by wire transfer of federal funds to a
bank designated by the party receiving such funds.

     (b) The certificates representing the Shares shall bear an appropriate
legend relating to the fact that such Shares have not been registered under the
Securities Act of 1933, as amended (the "Securities Act").

     5. Listing of Shares; Filings; Governmental Consents. Subject to applicable
law and the rules and regulations of the NYSE, the AMEX or the Nasdaq, as the
case may be, after the Option becomes exercisable hereunder, the Grantor will
promptly file an application to list the Shares on the NYSE or the AMEX or quote
the Shares on Nasdaq, as the case may be, and will use its reasonable best
efforts to obtain approval of such listing and to effect all necessary filings
by the Grantor under the HSR Act and the applicable laws of each state and
foreign jurisdiction; provided, however, that if the Grantor is unable to effect
such listing by the Closing Date, the Grantor will nevertheless be obligated to
deliver the Shares upon the Closing Date. Each of the parties hereto will use
its reasonable best efforts to obtain consents of all third parties and
governmental authorities, if any, necessary to the consummation of the
transactions contemplated.

     6. Repurchase of Shares. If by the date that is the first anniversary of
the date the Merger Agreement was terminated pursuant to the terms thereof (the
"Merger Termination Date"), neither the Grantee nor any other Person has
acquired more than fifty percent (excluding the Shares) of the shares of
outstanding Common Stock, then the Grantor has the right to purchase (the
"Repurchase Right") all, but not less than all, of the Shares acquired upon
exercise of this Option at the greater of (i) the Purchase Price or (ii) the
average of the last sales prices for shares of Common Stock on the five trading
days ending five days prior to the date the Grantor gives written notice of its
intention to exercise the Repurchase Right. If the Grantor does not exercise the
Repurchase Right within thirty days following the end of the one-year period
after the Merger Termination Date, the Repurchase Right lapses. In the event the
Grantor wishes to exercise the Repurchase Right, the Grantor shall send a
written notice to the Grantee specifying a date (not later than 20 business days
and not earlier than 10 business days following the date such notice is given)
for the closing of such purchase.

     7. Sale of Shares. At any time prior to the first anniversary of the Merger
Termination Date, the Grantee shall have the right to sell (the "Sale Right") to
the Grantor all, but not less than all, of the Shares acquired upon exercise of
this Option at the greater of (i) the Purchase Price or (ii) the average of the
last sales prices for shares of Common Stock on the five trading days ending
five days prior to the date the Grantee gives written notice of its intention to
exercise the Sale Right. If the Grantee does not exercise the Sale Right prior
to the first anniversary of the Merger Termination Date, the Sale Right
terminates. In the event the Grantee wishes to exercise the Sale Right, the
Grantee shall send a written notice to the Grantor specifying a date not later
than 20 business days and not earlier than 10 business days following the date
such notice is given for the closing of such sale.

     8. Registration Rights. (a) In the event that the Grantee shall desire to
sell any of the Shares within three years after the purchase of such Shares
pursuant hereto, and such sale requires, in the opinion of counsel to the
Grantee, which opinion shall be reasonably satisfactory to the Grantor and its
counsel, registration of such Shares under the Securities Act, the Grantor will
cooperate with the Grantee and any underwriters in registering such Shares for
resale, including, without limitation, promptly filing a registration statement,
including if requested by Grantee a "shelf" registration statement under Rule
145 under the Securities Act or any successor provision, which complies with the
requirements of applicable federal and state securities laws, and entering into
an underwriting agreement with such underwriters upon such terms and conditions
as are customarily contained in underwriting agreements with respect to
secondary distributions; provided, however, that the Grantor shall not be
required to have declared effective more than one registration statement
hereunder and shall be entitled to delay the filing or effectiveness of any
registration statement for up to 180 days if the offering would, in the judgment
of the Board of Directors of the Grantor, require premature disclosure of any
material corporate development or material transaction involving the Grantor or
interfere with any previously planned securities offering by the Grantor.

     (b) If the Common Stock is registered pursuant to the provisions of this
Section 8, the Grantor agrees (i) to furnish copies of the registration
statement and the prospectus relating to the Shares covered thereby in
                                       -3-
   174

such numbers as the Grantee may from time to time reasonably request and (ii) if
any event shall occur as a result of which it becomes necessary to amend or
supplement any registration statement or prospectus, to prepare and file under
the applicable securities laws such amendments and supplements as may be
necessary to keep available for at least 120 days a prospectus covering the
Common Stock meeting the requirements of such securities laws, and to furnish
the Grantee such numbers of copies of the registration statement and prospectus
as amended or supplemented as may reasonably be requested. The Grantor shall
bear the cost of the registration, including, but not limited to, all
registration and filing fees, printing expenses, and fees and disbursements of
counsel and accountants for the Grantor, except that the Grantee shall pay the
fees and disbursements of its counsel, and the underwriting fees and selling
commissions applicable to the shares of Common Stock sold by the Grantee. The
Grantor shall indemnify and hold harmless (i) Grantee, its affiliates and its
officers and directors and (ii) each underwriter and each person who controls
any underwriter within the meaning of the Securities Act or the Securities
Exchange Act of 1934, as amended (collectively, the "Underwriters") ((i) and
(ii) being referred to as "Indemnified Parties") against any losses, claims,
damages, liabilities or expenses, to which the Indemnified Parties may become
subject, insofar as such losses, claims, damages, liabilities (or actions in
respect thereof) and expenses arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained or
incorporated by reference in any registration statement filed pursuant to this
paragraph, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading; provided, however, that the Grantor will
not be liable in any such case to the extent that any such loss, liability,
claim, damage or expense arises out of or is based upon an untrue statement or
alleged untrue statement in or omission or alleged omission from any such
documents in reliance upon and in conformity with written information furnished
to Grantor by the Indemnified Parties expressly for use or incorporation by
reference therein.

     (c) The Grantee shall indemnify and hold harmless the Grantor, its
affiliates and its officers and directors against any losses, claims, damages,
liabilities or expenses to which the Grantor, its affiliates and its officers
and directors may become subject, insofar as such losses, claims, damages,
liabilities (or actions in respect thereof) and expenses arise out of or are
based upon any untrue statement of any material fact contained or incorporated
by reference in any registration statement filed pursuant to this paragraph, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in reliance upon and in conformity with written
information furnished to the Grantor by the Grantee specifically for use or
incorporation by reference therein.

     9. Expenses. Each party hereto shall pay its own expenses incurred in
connection with this Agreement, except as otherwise specifically provided
herein.

     10. Specific Performance. The Grantor acknowledges that if the Grantor
fails to perform any of its obligations under this Agreement immediate and
irreparable harm or injury would be caused to the Grantee for which money
damages would not be an adequate remedy. In such event, the Grantor agrees that
the Grantee shall have the right, in addition to any other rights it may have,
to specific performance of this Agreement. Accordingly, if the Grantee should
institute an action or proceeding seeking specific enforcement of the provisions
hereof, the Grantor hereby waives the claim or defense that the Grantee has an
adequate remedy at law and hereby agrees not to assert in any such action or
proceeding the claim or defense that such a remedy at law exists. The Grantor
further agrees to waive any requirements for the securing or posting of any bond
in connection with obtaining any such equitable relief.

     15. Severability. The invalidity or unenforceability of any provision of
this Agreement in any jurisdiction shall not affect the validity or
enforceability of any other provision of this Agreement in such jurisdiction, or
the validity or enforceability of any provision of this Agreement in any other
jurisdiction.

     16. Governing Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Pennsylvania, regardless of the laws
that might otherwise govern under the applicable principles of conflicts of laws
thereof.

     17. Counterparts. This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when two or more counterparts have been signed by each of
the parties and delivered to the other parties, it being understood that all
parties need not sign the same counterpart.

     18. Parties in Interest. This Agreement shall inure to the benefit of and
be binding upon the parties named herein and their respective successors and
assigns; provided, however, that such successor in interest or assigns shall
agree to be bound by the provisions of this Agreement. Nothing in this
Agreement, express or implied, is intended to confer upon any person other than
the Grantor or the Grantee, or their successors or assigns, any rights or
remedies under or by reason of this Agreement.

     19. Corporate Authorization. The Grantor agrees to take all necessary
corporate action to authorize and reserve the Shares issuable upon exercise of
the Option and to insure that, when issued and delivered by the Grantor upon
exercise of the Option and paid for by Grantee as contemplated hereby, the
Shares will be duly authorized, validly issued, fully paid and nonassessable and
free of preemptive rights.

     20. Assignment. No party to this Agreement may assign any of its rights or
obligations under this Agreement without the prior written consent of the other
party hereto, except that the Grantee may assign its rights and obligations
hereunder to any of its direct or indirect wholly owned subsidiaries, but no
such transfer shall relieve the Grantee of its obligations hereunder if such
transferee does not perform such obligations.

     21. Termination. The right to exercise the Option granted pursuant to this
Agreement shall terminate at the earliest of (i) the Effective Time (as defined
in the Merger Agreement), (ii) if the Option is not exercised within 12 months
days after first becoming exercisable and (iii) if not then exercisable, thirty
days after termination of the Merger Agreement in accordance with its terms (the
dates referred to in clause (ii) and (iii) being hereinafter referred to as the
"Termination Date"); provided, however, that if the Option cannot be exercised
or the Shares cannot be delivered to Grantee upon such exercise because the
conditions set forth in Section 3(a), (b) or (c) hereof have not yet been
satisfied, the Termination Date shall be extended until thirty days after such
impediment to exercise or delivery has been removed.

     22. Profit Limitation. (a) Notwithstanding any other provision of this
Agreement or the Merger Agreement, in no event shall the Grantee's Total Profit
(as hereinafter defined) exceed $30 million and, if it otherwise would exceed
such amount, the Grantee shall repay such excess amount to Grantor in cash (or
the purchase price for purposes of Section 6 or 7, as applicable, shall be
reduced) so that Grantee's Total Profit shall not exceed $30 million after
taking into account the foregoing actions.

     Notwithstanding any other provision of this Agreement, this Option may not
be exercised for a number of Shares as would, as of the date of the Stock
Exercise Notice, result in a Notional Total Profit (as defined below) of more
than $15 million and, if exercise of the Option otherwise would exceed such
amount, the Grantee, at its discretion, may increase the Purchase Price for that
number of Shares set forth in the Stock Exercise Notice so that the Notional
Total Profit shall not exceed $15 million; provided, however, that nothing in
this sentence shall restrict any exercise of the Option permitted hereby on any
subsequent date at the Purchase Price set forth in Section 1(a) hereof.

     As used herein, the term "Total Profit" shall mean the aggregate amount
(before taxes) of the following: (i)(x) the amount of cash received by Grantee
pursuant to Sections 7.3(b)(ii) and (c) (ii) of the Merger Agreement and Section
1(c) hereof, less (y) any repayment of such cash to Grantor, (ii)(x) the amount
received by Grantee pursuant to the Grantor's repurchase of Shares pursuant to
Sections 6 or 7 hereof, less

                                       -6-
   177

(y) the Grantee's purchase price for such Shares, and (iii)(x) the net cash
amounts received by Grantee pursuant to the sale of Shares (or any other
securities into or for which such Shares are converted or exchanged) to any
unaffiliated party, less (y) the Grantee's purchase price for such Shares.

     As used herein, the term "Notional Total Profit" with respect to any number
of Shares as to which Grantee may propose to exercise this Option shall be the
Total Profit determined as of the date of the Stock Exercise Notice assuming
that this Option was exercised on such date for such number of Shares and
assuming that such Shares, together with all Shares acquired upon exercise of
the Option and held by Grantee and its affiliates as of such date, were sold for
cash at the closing market price for the Common Stock as of the close of
business on the preceding trading day (less customary brokerage commissions).

     23. Public Announcement. Grantee and Grantor shall consult with each other
before issuing any press release or otherwise making any public statement with
respect to this Option and shall not issue any such press release or make any
such public statement prior to such consultation and the receipt of approval
therefor by the other party, which consent shall not be unreasonably withheld,
except as may be required by law, court process or by stock exchange rules.

     IN WITNESS WHEREOF, the Grantee and the Grantor have caused this Agreement
to be duly executed and delivered on the day and year first above written.

                       MOTIVEPOWER STOCK OPTION AGREEMENT

     STOCK OPTION AGREEMENT dated as of June 2, 1999 (the "Agreement") between
MotivePower Industries, Inc., a Pennsylvania corporation (the "Grantor") and
Westinghouse Air Brake Company, a Delaware corporation (the "Grantee").

     WHEREAS, the Grantor and the Grantee are entering into an Agreement and
Plan of Merger dated as of the date hereof (the "Merger Agreement"), which
provides, among other things, for the merger of Grantee with and into Grantor
(the "Merger");

     WHEREAS, as a condition and inducement to Grantee's willingness to enter
into the Merger Agreement, the Grantee has requested that the Grantor grant to
the Grantee an option to purchase up to 5,133,655 shares of Common Stock, par
value $0.01 per share, of the Grantor (the "Common Stock"), upon the terms and
subject to the conditions hereof; and

     WHEREAS, in order to induce the Grantee to enter into the Merger Agreement,
the Grantor is willing to grant the Grantee the requested option.

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:

     1. The Option; Exercise; Payment of Spread. (a) Contemporaneously herewith
the Grantee and the Grantor are entering into the Merger Agreement. Subject to
the other terms and conditions set forth herein, the Grantor hereby grants to
the Grantee an irrevocable option (the "Option") to purchase up to 5,133,655
shares of Common Stock (the "Shares") at a cash purchase price equal to $16.625
per share (the "Purchase Price"). The Option may be exercised by the Grantee, in
whole or in part, at any time, or from time to time, following (but not prior
to) the occurrence of one of the events set forth in Section 3(c) hereof, and
prior to the termination of the Option in accordance with the terms of this
Agreement.

     (b) In the event the Grantee wishes to exercise the Option, the Grantee
shall send a written notice to the Grantor (the "Stock Exercise Notice")
specifying a date (subject to the HSR Act (as defined below) and any other
applicable regulatory approvals) not later than 10 business days and not earlier
than three business days following the date such notice is given for the closing
of such purchase.

     (c) If at any time the Option is then exercisable pursuant to the terms of
Section 1(a) hereof, the Grantee may elect, in lieu of exercising the Option to
purchase Shares provided in Section 1(a) hereof, to send a written notice to the
Grantor (the "Cash Exercise Notice") specifying a date not later than 20
business days and not earlier than 10 business days following the date such
notice is given on which date the Grantor shall pay to the Grantee an amount in
cash equal to the Spread (as hereinafter defined) multiplied by all or such
portion of the Shares subject to the Option as Grantee shall specify. As used
herein, "Spread" shall mean the excess, if any, over the Purchase Price of the
higher (x) if applicable, the highest price per share of Common Stock (including
any brokerage commissions, transfer taxes and soliciting dealers' fees) paid or
proposed to be paid by any person pursuant to any Takeover Proposal (as defined
in the Merger Agreement) (the "Alternative Purchase Price") or (y) the closing
price of the shares of Common Stock on the New York Stock Exchange (the "NYSE")
Composite Tape, the American Stock Exchange (the "AMEX") or The Nasdaq National
Market (the "Nasdaq"), as the case may be, on the last trading day immediately
prior to the date of the Cash Exercise Notice (the "Closing Price"). If the
Alternative Purchase Price includes any property other than cash, the
Alternative Purchase Price shall be the sum of (i) the fixed cash amount, if
any, included in the Alternative Purchase Price plus (ii) the fair market value
of such other property. If such other property consists of securities with an
existing public trading market, the average of the closing prices (or the
average of the closing bid and asked prices if closing prices are unavailable)
for such securities in their principal public trading market on the five trading
days ending five days prior to the date of the Cash Exercise Notice shall be
deemed to equal the fair market value of such property. If such other property
consists of something other than cash or securities with an existing public
trading market and, as of the payment date for the Spread, agreement on the
value of such other property has not been reached, the Alternative Purchase
Price shall be deemed to equal the Closing Price. Upon exercise of its right to
receive cash pursuant to this Section 1(c), the obligations of the Grantor to
deliver Shares pursuant to Section 4 shall
   181

be terminated with respect to such number of Shares for which the Grantee shall
have elected to be paid the Spread.

     2. Adjustments. (a) In the event of any change in the number of issued and
outstanding shares of Common Stock by reason of any stock dividend, stock split,
split-up, recapitalization, merger or other change in the corporate or capital
structure of the Grantor, the number of Shares subject to this Option and the
purchase price per Share shall be appropriately adjusted to restore the Grantee
to its rights hereunder, including its right to purchase Shares representing 19%
of the capital stock of the Grantor entitled to vote generally for the election
of the directors of Grantor which is issued and outstanding immediately prior to
the exercise of the Option.

     (b) Without limiting the parties' relative rights and obligations under the
Merger Agreement, in the event that Grantor enters into an agreement (i) to
consolidate with or merge into any person, other than Grantee or one of its
subsidiaries, and Grantor will not be the continuing or surviving corporation in
such consolidation or merger, (ii) to permit any person, other than Grantee or
one of its subsidiaries, to merge into Grantor, and Grantor will be the
continuing or surviving corporation, but in connection with such merger, the
shares of Common Stock outstanding immediately prior to the consummation of such
merger will be changed into or exchanged for stock or other securities of
Grantor or any other person or cash or any other property, or the shares of
Common Stock outstanding immediately prior to the consummation of such merger
will, after such merger, represent less than 50% of the outstanding voting
securities of the merged company, or (iii) to sell or otherwise transfer all or
substantially all of its assets to any person, other than Grantee or one of its
subsidiaries, then, and in each such case, the agreement governing such
transaction will make proper provision so that the Option will, upon the
consummation of any such transaction and upon the terms and conditions set forth
herein, be converted into, or exchanged for, an option with identical terms
appropriately adjusted to acquire the number and class of shares or other
securities or property that Grantee would have received in respect to Common
Stock if the Option had been exercised immediately prior to such consolidation,
merger, sale, or transfer, or the record date therefor, as applicable and make
any other necessary adjustments.

     3. Conditions to Delivery of Shares. The Grantor's obligation to deliver
Shares upon exercise of the Option is subject only to the conditions that:

     (a) No preliminary or permanent injunction or other order issued by any
federal or state court of competent jurisdiction in the United States
prohibiting the delivery of the Shares shall be in effect; and

     (b) Any applicable waiting periods under the Hart- Scott-Rodino Antitrust
Improvements Act of 1976 (the "HSR Act") shall have expired or been terminated;
and

     (c) (i) the Merger Agreement is terminated pursuant to Section 7.1(d)(ii)
and either (I) a Takeover Proposal with respect to Grantor shall have been made
after the date of the Merger Agreement and prior to the Grantor Stockholders
Meeting (as defined in the Merger Agreement) or (II) the Board of Directors of
Grantor shall not have recommended or shall have modified in a manner materially
adverse to Grantee its recommendation of the Merger Agreement and the Merger; or
(ii) the Merger Agreement is terminated pursuant to Section 7.1(e), 7.1(f) or
7.1(g) of the Merger Agreement.

     4. The Closing. (a) Any closing hereunder shall take place on the date
specified by the Grantee in its Stock Exercise Notice or Cash Exercise Notice,
as the case may be, at 9:00 A.M., local time, at the offices of Doepken Keevican
& Weiss, 58th Floor, USX Tower, 600 Grant Street, Pittsburgh, Pennsylvania, or,
if the conditions set forth in Section 3(a), (b) or (c) have not then been
satisfied, on the second business day following the satisfaction of such
conditions, or at such other time and place as the parties hereto may agree (the
"Closing Date"). On the Closing Date, (i) in the event of a closing pursuant to
Section 1(b) hereof, the Grantor will deliver to the Grantee a certificate or
certificates representing the Shares in the denominations designated by the
Grantee in its Stock Exercise Notice and the Grantee will purchase such Shares
from the Grantor at the price per Share equal to the Purchase Price or (ii) in
the event of a closing pursuant to Section 1(c) hereof, the Grantor will deliver
to the Grantee cash in an amount determined pursuant to

                                       -2-
   182

Section 1(c) hereof. Any payment made pursuant to this Agreement shall be made
by certified or official bank check or by wire transfer of federal funds to a
bank designated by the party receiving such funds.

     (b) The certificates representing the Shares shall bear an appropriate
legend relating to the fact that such Shares have not been registered under the
Securities Act of 1933, as amended (the "Securities Act").

     5. Listing of Shares; Filings; Governmental Consents. Subject to applicable
law and the rules and regulations of the NYSE, the AMEX or the Nasdaq, as the
case may be, after the Option becomes exercisable hereunder, the Grantor will
promptly file an application to list the Shares on the NYSE or the AMEX or quote
the Shares on Nasdaq, as the case may be, and will use its reasonable best
efforts to obtain approval of such listing and to effect all necessary filings
by the Grantor under the HSR Act and the applicable laws of each state and
foreign jurisdiction; provided, however, that if the Grantor is unable to effect
such listing by the Closing Date, the Grantor will nevertheless be obligated to
deliver the Shares upon the Closing Date. Each of the parties hereto will use
its reasonable best efforts to obtain consents of all third parties and
governmental authorities, if any, necessary to the consummation of the
transactions contemplated.

     6. Repurchase of Shares. If by the date that is the first anniversary of
the date the Merger Agreement was terminated pursuant to the terms thereof (the
"Merger Termination Date"), neither the Grantee nor any other Person has
acquired more than fifty percent (excluding the Shares) of the shares of
outstanding Common Stock, then the Grantor has the right to purchase (the
"Repurchase Right") all, but not less than all, of the Shares acquired upon
exercise of this Option at the greater of (i) the Purchase Price or (ii) the
average of the last sales prices for shares of Common Stock on the five trading
days ending five days prior to the date the Grantor gives written notice of its
intention to exercise the Repurchase Right. If the Grantor does not exercise the
Repurchase Right within thirty days following the end of the one-year period
after the Merger Termination Date, the Repurchase Right lapses. In the event the
Grantor wishes to exercise the Repurchase Right, the Grantor shall send a
written notice to the Grantee specifying a date (not later than 20 business days
and not earlier than 10 business days following the date such notice is given)
for the closing of such purchase.

     7. Sale of Shares. At any time prior to the first anniversary of the Merger
Termination Date, the Grantee shall have the right to sell (the "Sale Right") to
the Grantor all, but not less than all, of the Shares acquired upon exercise of
this Option at the greater of (i) the Purchase Price or (ii) the average of the
last sales prices for shares of Common Stock on the five trading days ending
five days prior to the date the Grantee gives written notice of its intention to
exercise the Sale Right. If the Grantee does not exercise the Sale Right prior
to the first anniversary of the Merger Termination Date, the Sale Right
terminates. In the event the Grantee wishes to exercise the Sale Right, the
Grantee shall send a written notice to the Grantor specifying a date not later
than 20 business days and not earlier than 10 business days following the date
such notice is given for the closing of such sale.

     8. Registration Rights. (a) In the event that the Grantee shall desire to
sell any of the Shares within three years after the purchase of such Shares
pursuant hereto, and such sale requires, in the opinion of counsel to the
Grantee, which opinion shall be reasonably satisfactory to the Grantor and its
counsel, registration of such Shares under the Securities Act, the Grantor will
cooperate with the Grantee and any underwriters in registering such Shares for
resale, including, without limitation, promptly filing a registration statement,
including if requested by Grantee a "shelf" registration statement under Rule
145 under the Securities Act or any successor provision, which complies with the
requirements of applicable federal and state securities laws, and entering into
an underwriting agreement with such underwriters upon such terms and conditions
as are customarily contained in underwriting agreements with respect to
secondary distributions; provided, however, that the Grantor shall not be
required to have declared effective more than one registration statement
hereunder and shall be entitled to delay the filing or effectiveness of any
registration statement for up to 180 days if the offering would, in the judgment
of the Board of Directors of the Grantor, require premature disclosure of any
material corporate development or material transaction involving the Grantor or
interfere with any previously planned securities offering by the Grantor.

     (b) If the Common Stock is registered pursuant to the provisions of this
Section 8, the Grantor agrees (i) to furnish copies of the registration
statement and the prospectus relating to the Shares covered thereby in
                                       -3-
   183

such numbers as the Grantee may from time to time reasonably request and (ii) if
any event shall occur as a result of which it becomes necessary to amend or
supplement any registration statement or prospectus, to prepare and file under
the applicable securities laws such amendments and supplements as may be
necessary to keep available for at least 120 days a prospectus covering the
Common Stock meeting the requirements of such securities laws, and to furnish
the Grantee such numbers of copies of the registration statement and prospectus
as amended or supplemented as may reasonably be requested. The Grantor shall
bear the cost of the registration, including, but not limited to, all
registration and filing fees, printing expenses, and fees and disbursements of
counsel and accountants for the Grantor, except that the Grantee shall pay the
fees and disbursements of its counsel, and the underwriting fees and selling
commissions applicable to the shares of Common Stock sold by the Grantee. The
Grantor shall indemnify and hold harmless (i) Grantee, its affiliates and its
officers and directors and (ii) each underwriter and each person who controls
any underwriter within the meaning of the Securities Act or the Securities
Exchange Act of 1934, as amended (collectively, the "Underwriters") ((i) and
(ii) being referred to as "Indemnified Parties") against any losses, claims,
damages, liabilities or expenses, to which the Indemnified Parties may become
subject, insofar as such losses, claims, damages, liabilities (or actions in
respect thereof) and expenses arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained or
incorporated by reference in any registration statement filed pursuant to this
paragraph, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading; provided, however, that the Grantor will
not be liable in any such case to the extent that any such loss, liability,
claim, damage or expense arises out of or is based upon an untrue statement or
alleged untrue statement in or omission or alleged omission from any such
documents in reliance upon and in conformity with written information furnished
to Grantor by the Indemnified Parties expressly for use or incorporation by
reference therein.

     (c) The Grantee shall indemnify and hold harmless the Grantor, its
affiliates and its officers and directors against any losses, claims, damages,
liabilities or expenses to which the Grantor, its affiliates and its officers
and directors may become subject, insofar as such losses, claims, damages,
liabilities (or actions in respect thereof) and expenses arise out of or are
based upon any untrue statement of any material fact contained or incorporated
by reference in any registration statement filed pursuant to this paragraph, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in reliance upon and in conformity with written
information furnished to the Grantor by the Grantee specifically for use or
incorporation by reference therein.

     9. Expenses. Each party hereto shall pay its own expenses incurred in
connection with this Agreement, except as otherwise specifically provided
herein.

     10. Specific Performance. The Grantor acknowledges that if the Grantor
fails to perform any of its obligations under this Agreement immediate and
irreparable harm or injury would be caused to the Grantee for which money
damages would not be an adequate remedy. In such event, the Grantor agrees that
the Grantee shall have the right, in addition to any other rights it may have,
to specific performance of this Agreement. Accordingly, if the Grantee should
institute an action or proceeding seeking specific enforcement of the provisions
hereof, the Grantor hereby waives the claim or defense that the Grantee has an
adequate remedy at law and hereby agrees not to assert in any such action or
proceeding the claim or defense that such a remedy at law exists. The Grantor
further agrees to waive any requirements for the securing or posting of any bond
in connection with obtaining any such equitable relief.

     11. Notice. All notices and other communications hereunder shall be in
writing and shall be deemed given when delivered personally, one day after being
delivered to a nationally recognized overnight courier or when telecopied (with
a confirmatory copy sent by such overnight courier) to the parties at the

this Agreement they shall be deemed to be followed by the words "without

     13. Entire Agreement. This Agreement (including the documents and the
instruments referred to herein) constitutes the entire agreement and supersedes
all prior agreements and understandings, both written and oral, among the
parties with respect to the subject matter hereof.

     14. Amendment. This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto.

     15. Severability. The invalidity or unenforceability of any provision of
this Agreement in any jurisdiction shall not affect the validity or
enforceability of any other provision of this Agreement in such jurisdiction, or
the validity or enforceability of any provision of this Agreement in any other
jurisdiction.

     16. Governing Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Pennsylvania, regardless of the laws
that might otherwise govern under the applicable principles of conflicts of laws
thereof.

     17. Counterparts. This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when two or more counterparts have been signed by each of
the parties and delivered to the other parties, it being understood that all
parties need not sign the same counterpart.

     18. Parties in Interest. This Agreement shall inure to the benefit of and
be binding upon the parties named herein and their respective successors and
assigns; provided, however, that such successor in interest or assigns shall
agree to be bound by the provisions of this Agreement. Nothing in this
Agreement, express or implied, is intended to confer upon any person other than
the Grantor or the Grantee, or their successors or assigns, any rights or
remedies under or by reason of this Agreement.

     19. Corporate Authorization. The Grantor agrees to take all necessary
corporate action to authorize and reserve the Shares issuable upon exercise of
the Option and to insure that, when issued and delivered by the Grantor upon
exercise of the Option and paid for by Grantee as contemplated hereby, the
Shares will be duly authorized, validly issued, fully paid and nonassessable and
free of preemptive rights.

     20. Assignment. No party to this Agreement may assign any of its rights or
obligations under this Agreement without the prior written consent of the other
party hereto, except that the Grantee may assign its rights and obligations
hereunder to any of its direct or indirect wholly owned subsidiaries, but no
such transfer shall relieve the Grantee of its obligations hereunder if such
transferee does not perform such obligations.

     21. Termination. The right to exercise the Option granted pursuant to this
Agreement shall terminate at the earliest of (i) the Effective Time (as defined
in the Merger Agreement), (ii) if the Option is not exercised within 12 months
days after first becoming exercisable and (iii) if not then exercisable, thirty
days after termination of the Merger Agreement in accordance with its terms (the
dates referred to in clause (ii) and (iii) being hereinafter referred to as the
"Termination Date"); provided, however, that if the Option cannot be exercised
or the Shares cannot be delivered to Grantee upon such exercise because the
conditions set forth in Section 3(a), (b) or (c) hereof have not yet been
satisfied, the Termination Date shall be extended until thirty days after such
impediment to exercise or delivery has been removed.

     22. Profit Limitation. (a) Notwithstanding any other provision of this
Agreement or the Merger Agreement, in no event shall the Grantee's Total Profit
(as hereinafter defined) exceed $30 million and, if it otherwise would exceed
such amount, the Grantee shall repay such excess amount to Grantor in cash (or
the purchase price for purposes of Section 6 or 7, as applicable, shall be
reduced) so that Grantee's Total Profit shall not exceed $30 million after
taking into account the foregoing actions.

     Notwithstanding any other provision of this Agreement, this Option may not
be exercised for a number of Shares as would, as of the date of the Stock
Exercise Notice, result in a Notional Total Profit (as defined below) of more
than $15 million and, if exercise of the Option otherwise would exceed such
amount, the Grantee, at its discretion, may increase the Purchase Price for that
number of Shares set forth in the Stock Exercise Notice so that the Notional
Total Profit shall not exceed $15 million; provided, however, that nothing in
this sentence shall restrict any exercise of the Option permitted hereby on any
subsequent date at the Purchase Price set forth in Section 1(a) hereof.

     As used herein, the term "Total Profit" shall mean the aggregate amount
(before taxes) of the following: (i)(x) the amount of cash received by Grantee
pursuant to Sections 7.3(d)(ii) and (e) (ii) of the Merger Agreement and Section
1(c) hereof, less (y) any repayment of such cash to Grantor, (ii)(x) the amount
received by Grantee pursuant to the Grantor's repurchase of Shares pursuant to
Sections 6 or 7 hereof, less

                                       -6-
   186

(y) the Grantee's purchase price for such Shares, and (iii)(x) the net cash
amounts received by Grantee pursuant to the sale of Shares (or any other
securities into or for which such Shares are converted or exchanged) to any
unaffiliated party, less (y) the Grantee's purchase price for such Shares.

     As used herein, the term "Notional Total Profit" with respect to any number
of Shares as to which Grantee may propose to exercise this Option shall be the
Total Profit determined as of the date of the Stock Exercise Notice assuming
that this Option was exercised on such date for such number of Shares and
assuming that such Shares, together with all Shares acquired upon exercise of
the Option and held by Grantee and its affiliates as of such date, were sold for
cash at the closing market price for the Common Stock as of the close of
business on the preceding trading day (less customary brokerage commissions).

     23. Public Announcement. Grantor and Grantee shall consult with each other
before issuing any press release or otherwise making any public statement with
respect to this Option and shall not issue any such press release or make any
such public statement prior to such consultation and the receipt of approval
therefor by the other party, which consent shall not be unreasonably withheld,
except as may be required by law, court process or by stock exchange rules.

     IN WITNESS WHEREOF, the Grantee and the Grantor have caused this Agreement
to be duly executed and delivered on the day and year first above written.

Board of Directors
MotivePower Industries, Inc.
Two Gateway Center
Fourteenth Floor
Pittsburgh, Pennsylvania 15222

Members of the Board of Directors:

     MotivePower Industries, Inc. (the "Company") and Westinghouse Air Brake
Company ("WABCO") have entered into an Agreement and Plan of Merger, dated as of
June 2, 1999 (the "Agreement"). The Agreement provides for, among other things,
a merger of WABCO with and into the Company (the "Merger"), pursuant to which
each outstanding share of WABCO's common stock, par value $.01 per share ("WABCO
Shares"), will be converted into 1.3 shares (the "Exchange Ratio") of the common
stock, par value $.01 per share, of the Company ("Company Shares").

     You have asked us to advise you with respect to the fairness, from a
financial point of view, to the Company of the Exchange Ratio.

     In arriving at the opinion set forth below, we have, among other things:

      1. Reviewed certain publicly available business and financial information
         relating to the Company and WABCO which we deemed to be relevant;

      2. Reviewed certain internal financial information, including financial
         forecasts, relating to the business, earnings, cash flow, assets,
         liabilities and prospects of the Company and WABCO, as well as the
         amount and timing of the cost savings and related expenses and
         synergies expected to result from the Merger (the "Expected
         Synergies"), in each case prepared and furnished to us by the Company
         and WABCO;

      3. Conducted discussions with members of senior management and
         representatives of the Company and WABCO concerning the matters
         described in clauses 1 and 2 above, as well as their respective
         businesses and prospects before and after giving effect to the Merger,
         and the Expected Synergies;

      4. Reviewed the market prices and valuation multiples for Company Shares
         and WABCO Shares and compared them with those of certain
         publicly-traded companies which we deemed to be relevant;

      5. Reviewed the results of operations of the Company and WABCO and
         compared them with those of certain publicly-traded companies which we
         deemed to be relevant;

      6. Compared the proposed financial terms of the Merger with the financial
         terms of certain other transactions which we deemed to be relevant;

      7. Participated in certain discussions and negotiations among
         representatives of the Company and WABCO and their financial and legal
         advisors;

      8. Reviewed the potential pro forma impact of the Merger;

      9. Reviewed the Agreement; and

     10. Performed such other financial studies, analyses and investigations and
         reviewed such other information as we considered appropriate for
         purposes of this opinion.
   188

     In preparing our opinion, we have assumed and relied on the accuracy and
completeness of all of the financial and other information provided to or
discussed with us or publicly available, and we have not assumed any
responsibility for independently verifying any of such information. In addition,
we have not reviewed any of the books and records of the Company or WABCO, or
assumed any responsibility for conducting a physical inspection of the
properties or facilities of the Company or WABCO or for making or obtaining an
independent valuation or appraisal of any of the assets or liabilities of the
Company or WABCO, and no such independent valuation or appraisal was provided to
us. We have also assumed and relied upon the reasonableness and accuracy of the
financial forecast information and the Expected Synergies furnished to or
discussed with us by the Company and WABCO, we have assumed that they have been
reasonably prepared in good faith and on bases reflecting the best currently
available estimates and judgments of the Company's and WABCO's respective
managements as to the expected future financial performance of, and expenses and
benefits to, the Company or WABCO, as the case may be, and the Expected
Synergies, and we have assumed that such financial forecast information and
Expected Synergies will be realized in the amounts and at the times indicated
thereby. We express no opinion as to such financial forecast information and
Expected Synergies or as to the assumptions upon which they are based. You have
informed us, and we have assumed, that the Merger will be accounted for as a
pooling of interests under generally accepted accounting principles and will
qualify as a tax-free reorganization for United States Federal income tax
purposes.

     For purposes of rendering this opinion we have assumed, in all respects
material to our analysis, that the representations and warranties of each party
to the Agreement and all related documents and instruments (collectively, the
"Documents") contained therein are true and correct,that each party to the
Documents will perform all of the covenants and agreements required to be
performed by such party under such Documents and that all conditions to the
consummation of the Merger will be satisfied without waiver or modification
thereof. We have also assumed that all material governmental, regulatory or
other consents and approvals required in connection with the Merger will be
obtained, and that in the course of obtaining any necessary consents and
approvals, or any amendments, modifications or waivers to any documents to which
either the Company or WABCO is a party, no restrictions will be imposed or
amendments, modifications or waivers made that would have any material adverse
effect on the contemplated benefits of the Merger. Our opinion is necessarily
based upon market, economic and other conditions and circumstances as they exist
and can be evaluated on, and on the information made available to us as of, the
date hereof. We are not expressing any opinion herein as to the prices at or
trading ranges in which Company Shares or WABCO Shares may trade at any time.

     In connection with performing our services for the Company, we have not
been authorized by the Company or the Board of Directors to solicit, nor have we
solicited, any third-party indications of interest for the acquisition of all or
any part of the Company.

     We are acting as financial advisor to the Company in connection with the
proposed Merger and will receive a fee from the Company for our services, a
major portion of which is contingent upon the consummation of the Merger. In the
past, we have provided financial advisory services to the Company and received
compensation for such services. In addition, the Company has agreed to indemnify
us for certain liabilities arising out of our engagement. In the ordinary course
of our business, we may actively trade the Company Shares and other securities
of the Company, as well as the WABCO Shares and other securities of WABCO, for
our own account and for the accounts of customers and, accordingly, may at any
time hold a long or short position in such securities.

     Our opinion addresses only the fairness from a financial point of view to
the Company of the Exchange Ratio, and we do not express any views on any other
terms of the Merger. Specifically, our opinion does not address the Company's
underlying business decision to effect the transactions contemplated by the
Agreement.

     It is understood that this letter is for the benefit and use of the Board
of Directors of the Company in its consideration of the Merger, and except for
inclusion in its entirety in any registration statement or proxy statement
required to be circulated to shareholders of the Company relating to the Merger,
may not be disseminated, quoted, referred to or reproduced at any time or in any
manner without our prior written
   189

consent. This opinion does not constitute a recommendation to any shareholder as
to how such shareholder should vote with respect to the Merger, and should not
be relied upon by any shareholder as such.

     On the basis of and subject to the foregoing, including the various
assumptions and limitations set forth herein, we are of the opinion that, as of
the date hereof, the Exchange Ratio is fair to the Company from a financial
point of view.

                                        Very truly yours,

                                        /s/ WASSERSTEIN PERELLA & CO., INC.

Gentlemen:

You have asked us to advise you with respect to the fairness to the stockholders
of Westinghouse Air Brake Company (the "Company") from a financial point of view
of the consideration to be received by such stockholders pursuant to the terms
of the Agreement and Plan of Merger, dated as of June 2, 1999 (the "Merger
Agreement"), among the Company and MotivePower Industries, Inc. (the
"Acquiror"). The Merger Agreement provides for the merger (the "Merger") of the
Company into the Acquiror and each outstanding share of common stock, par value
$.01 per share, of the Company being converted in the Merger into 1.30 shares
(the "Exchange Ratio") of common stock, par value $.01 per share, of the
Acquiror (the "Common Stock").

In arriving at our opinion, we have reviewed certain publicly available business
and financial information relating to the Company and the Acquiror, as well as
the Merger Agreement. We have also reviewed certain other information, including
financial forecasts, provided to us by the Company and the Acquiror, and have
met with the Company's and the Acquiror's management to discuss the business and
prospects of the Company and the Acquiror. We have also relied upon the views of
the Company's and the Acquiror's management concerning the business, operational
and strategic benefits and implications of the Merger, including financial
forecasts provided to us by the Company and the Acquiror relating to the
synergistic values and operating cost savings expected to be achieved through
the combination of the operations of the Company and the Acquiror.

We have also considered certain financial and stock market data of the Company
and the Acquiror, and we have compared those data with similar data for other
publicly held companies in businesses similar to the Company and the Acquiror
and we have considered the financial terms of certain other business
combinations and other transactions which have recently been effected. We also
considered such other information, financial studies, analyses and
investigations and financial, economic and market criteria which we deemed
relevant.

In connection with our review, we have not assumed any responsibility for
independent verification of any of the foregoing information and have relied on
its being complete and accurate in all material respects. With respect to the
financial forecasts, we have assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
Company's and the Acquiror's management as to the future financial performance
of the Company and the Acquiror and as to the cost savings and other potential
synergies (including the amount, timing and achievability thereof) anticipated
to result from the Merger. You also have informed us, and we have assumed, that
the Merger will be treated as a tax-free reorganization for federal income tax
purposes and accounted for as a pooling of interests in accordance with
generally accepted accounting principles. In addition, we have not been
requested to make, and have not made, an independent evaluation or appraisal of
the assets or liabilities (contingent or otherwise) of the Company or the
Acquiror, nor have we been furnished with any such evaluations or appraisals.
Our opinion is necessarily based upon financial, economic, market and other
conditions as they exist and can be evaluated on the date hereof. We are not
expressing any opinion as to the actual value of the Common Stock when issued to
the Company's stockholders pursuant to the Merger or the prices at which such
Common Stock will trade subsequent to the Merger. We were not requested to, and
did not, solicit third party indications of interest in acquiring all or any
part of the Company.
   191

We have acted as financial advisor to the Board of Directors in connection with
the Merger and will receive a fee for our services, a significant portion of
which is contingent upon the consummation of the Merger. In the past, we have
provided financial services to the Company unrelated to the proposed Merger, for
which services we have received compensation. In the ordinary course of
business, Credit Suisse First Boston and its affiliates may actively trade the
debt and equity securities of both the Company and the Acquiror for their own
accounts and for the accounts of customers and, accordingly, may at any time
hold long or short positions in such securities. As of the date hereof, Credit
Suisse First Boston owns approximately 581,300 shares of the Acquiror.

It is understood that this letter is for the information of the Board of
Directors in connection with its consideration of the Merger and does not
constitute a recommendation to any stockholder as to how such stockholder should
vote on the proposed Merger and is not to be quoted or referred to, in whole or
in part, in any registration statement, prospectus or proxy statement, or in any
other document used in connection with the offering or sale of securities, nor
shall this letter be used for any other purposes, without our prior written
consent.

Based upon and subject to the foregoing, it is our opinion that, as of the date
hereof, the Exchange Ratio is fair to the stockholders of the Company from a
financial point of view.

                                        Very truly yours,

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     MotivePower's charter and by-laws provide for indemnification of
MotivePower's directors and officers for liabilities and expenses that they may
incur in such capacities. The MotivePower charter provides that, to the fullest
extent permitted by Pennsylvania law, no director will be personally liable to
the corporation for or with respect to any acts or omissions in the performance
of his or her duties. Pennsylvania law permits a corporation to eliminate the
personal liability of its directors for monetary damages for any action taken or
failure to take any action unless: (1) such directors have breached or failed to
perform their duties; and (2) the breach or failure to perform constitutes
self-dealing, willful misconduct or recklessness. MotivePower has adopted such a
provision in its charter. However, a Pennsylvania corporation is not empowered
to eliminate personal liability where the responsibility or liability of a
director is pursuant to any criminal statute or is for the payment of taxes
pursuant to any federal, state or local law. Reference is made to MotivePower's
charter incorporated by reference as set forth below as Exhibit 3.1 hereto, and
by-laws set forth below as Exhibit 3.2 hereto.

     MotivePower also maintains directors and officers liability insurance which
provides for coverage against loss arising from claims made against directors
and officers in their capacity as such.

     MotivePower has agreed to indemnify, to the extent provided under WABCO's
charter and by-laws in effect on June 2, 1999, the individuals who on or before
the closing were officers or directors of WABCO or its subsidiaries with respect
to all acts or omissions before the closing by these individuals in these
capacities. MotivePower has also agreed to provide, for six years after the
closing, a directors' and officers' liability insurance and indemnification
policy that provides WABCO's officers and directors in office immediately prior
to the closing coverage substantially equivalent to WABCO's policy in effect on
June 2, 1999.

ITEM 22. UNDERTAKINGS.

(a) The undersigned Registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

          (i)  To include any prospectus required by section 10(a)(3) of the
     Securities Act of 1933;

          (ii) To reflect in the prospectus any facts or events arising after
     the effective date of the Registration Statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     Registration Statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20 percent change in the maximum aggregate
     offering price set forth in the "Calculation of Registration Fee" table in
     the effective registration statement; and

          (iii) To include any material information with respect to the plan of
     distribution not previously disclosed in the Registration Statement or any
     material change to such information in the Registration Statement.

     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at the time shall be deemed to be the initial bona
fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (4) That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the Registrant's annual report pursuant to Section
13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by
reference in the Registration Statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

     (5) That prior to any public reoffering of the securities registered
hereunder through use of a prospectus which is part of this Registration
Statement, by any person or party who is deemed to be an underwriter within the
meaning of Rule 145(c), the Registrant undertakes that such reoffering
prospectus will contain the information called for by the applicable
registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other items of
the applicable form.

     (6) That every prospectus (i) that is filed pursuant to paragraph (5)
immediately preceding, or (ii) that purports to meet the requirements of Section
10(a)(3) of the Securities Act of 1933 and is used in connection with an
offering of securities subject to Rule 415, will be filed as part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     (7) To respond to requests for information that is incorporated by
reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this
form, within one business day of receipt of such request, and to send the
incorporated documents by first class mail or other equally prompt means. This
includes information contained in documents filed subsequent to the effective
date of the Registration Statement through the date of responding to the
request.

                                      II-3
   195

     (8) To supply by means of a post-effective amendment all information
concerning a transaction, and the company being acquired involved therein, that
was not the subject of and included in the Registration Statement when it became
effective.

(b) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

                                      II-4
