ITEM 1. BUSINESS

GENERAL

On November 19, 1999 Westinghouse Air Brake Company (WABCO) completed its merger
with MotivePower Industries, Inc. WABCO was one of North America's largest
manufacturers of value-added equipment for locomotives, railway freight cars and
passenger transit vehicles. MotivePower Industries (MotivePower) was a leader in
the manufacturing and distribution of products for rail and other power related
industries, also providing a variety of related contract services.

We believe the merger resulted in North America's largest providers of
value-added, technology-based products and services for the rail industry. The
combined company, Westinghouse Air Brake Technologies Corporation, does business
as Wabtec Corporation. All references to "we", "our", "us", the "Company" and
"Wabtec" refer to Westinghouse Air Brake Technologies Corporation, a Delaware
corporation, and its subsidiaries. The merger was accounted for as a
"pooling-of-interests." Accordingly, the consolidated financial statements have
been restated giving effect to this transaction as if it had occurred as of the
beginning of the earliest period presented. The discussions that follow are
based on the combined companies for each year.

We believe that we maintain a market share in North America in excess of 50% for
our primary braking-related equipment and a significant market share in North
America for our other principal products. We also sell our products in Europe,
Africa, Australia, South America and Asia. Our major products are intended to
enhance safety, improve productivity and reduce maintenance costs for our
customers. Our major product offerings include electronic controls and monitors,
air brakes, traction motors, cooling equipment, turbochargers, low-horsepower
locomotives, couplers, door controls, draft gears and brake shoes. We
aggressively pursue technological advances with respect to both new product
development and product enhancements. The Company has its headquarters in
Wilmerding, Pennsylvania and has approximately 6,500 employees at facilities
throughout the world.

INDUSTRY OVERVIEW

The Company's operating results are strongly influenced by general economic
conditions, and the financial conditions and level of activity of the global
railroad industry. In 1999, favorable conditions generally prevailed in the
North American economy. As a result, U.S. railroads carried a record 1.4
trillion revenue ton-miles (defined as weight times distance traveled by Class I
railroads), the main indicator of activity in the industry, up 1.8 % from the
prior year. There can be no assurance that these favorable conditions will
continue. Rail traffic, in terms of both freight and passengers, is a key factor
underlying the demand for the Company's products. Government investment in
public rail transportation also plays a significant role. Additionally,
railroads continuously seek to increase the efficiency and productivity of their
rail operations in order to improve profitability. We design an array of
products to meet this goal and believe that through our products and service
offerings, we are well positioned to contribute to and benefit from the railroad
industry's drive to improve efficiency and productivity.

Demand for locomotive and freight car products was strong in 1999 due to
continued growth in revenue ton-miles, continued strong delivery of new
locomotives and freight cars, and the age of the industry's fleet of rolling
stock.

Currently, the active locomotive fleet in the North American market numbers
about 33,000 units, which include heavy-haul freight locomotives, commuter
locomotives and lower-horsepower, short-haul and terminal locomotives.
Deliveries of new, heavy-haul locomotives reached about 1,400 in 1999 as
railroads invested in modernizing a portion of their fleets. In 2000, the
Company expects the industry to deliver approximately 1,100 new locomotives.
Historically, the components, parts and maintenance, and overhaul segments of
the railroad industry, while still subject to the impact of rail traffic
fluctuations and capital investment cycles, have been more stable and less
cyclical than the new locomotive segment.

There are approximately 6,000 low-horsepower locomotives operating in
switcher/short-haul service in the U.S. and Canada, with an average age of 30
years. Demand for new state-of-the-art, low-horsepower locomotives has been
minimal since the early 1980s because the railroads have focused instead on
modernizing, rationalizing and downsizing their higher-horsepower freight
locomotive fleets. The Company believes that railroads may now begin to invest
in

                                        2
<PAGE>   4

lower-horsepower locomotives with advanced technology that can achieve higher
levels of productivity and efficiency. The Company has formed a strategic
alliance with an original equipment manufacturer (OEM) locomotive supplier to
market these locomotives, and it is currently building 50 of these units for a
specific customer.

Currently, the active freight car fleet in North America numbers about 1.3
million units. Deliveries of new freight cars reached a 20-year high of 75,685
units in 1998 and remained strong in 1999 with 74,223 as railroads and shippers
invested in modernizing their fleets. In 2000, the Company expects the industry
to deliver approximately 50,000 new freight cars, which would be approximately
the average delivery rate of the past 10 years.

Demand for fleet maintenance services is driven by the railroads' focus on cost
reduction and productivity improvements as the industry has consolidated over
recent decades, and as railroads consider outsourcing non-transportation
functions. When possible, the Company supplies its own component parts for use
in overhaul and maintenance under these contracts. In this manner, the
locomotive fleet maintenance contracts provide additional opportunities for
sales of component parts.

Demand for passenger transit original equipment manufacturer (OEM) and
aftermarket (i.e. replacement parts) products is driven by the replacement,
building and/or expansion programs of transit authorities. These programs are
funded in part by federal and state government programs, such as TEA-21
(Intermodal Surface Transportation and Efficiency Act), which is expected to
provide up to $42 billion nationally, subject to appropriations for
transit-related infrastructure through 2003.

Since the deregulation of the U.S. railroad industry in 1980, freight railroads
have reduced their equipment base, consolidated operations, and reduced
suppliers to reduce operating costs and improve their competitive position
compared to trucking companies, which compete with the railroad industry. In
addition, they have been consolidating and merging, hoping to achieve additional
operating and financial efficiencies that will allow them to compete more
effectively. The Company believes these consolidations offer opportunities to
increase business with the surviving railroads as these railroads seek operating
efficiencies through such means as outsourcing locomotive fleet maintenance and
components repair. In addition, the supplier base has been consolidating, and
the Company is a primary consolidator. The Company operates in a highly
competitive environment, and there can be no assurance that increased rail
traffic, higher fleet utilization, or other economically favorable industry
conditions will benefit the Company.

BUSINESS SEGMENTS AND PRODUCTS

Approximately 60% of our net sales in 1999 were derived from the sale of
aftermarket replacement parts, repair services and overhaul work purchased by
operators of rail vehicles such as railroads, transit authorities, utilities and
leasing companies (collectively, "end users" or the "aftermarket"). The balance
of our sales was directly to North American OEMs of locomotives, railway freight
cars and passenger transit vehicles. We believe that our substantial installed
base of OEM products is a significant competitive advantage for providing
products and services to the aftermarket because end-users often look to
purchase replacement parts from the OEM when they are safety and performance
related products. We believe that we are less adversely affected than our
competitors by fluctuations in domestic demand for new railroad vehicles because
of our substantial aftermarket and international sales.

Our products and services are delivered through two principal business segments,
the Freight Group and Transit Group. Financial information for these segments
has been restated in conjunction with the operational realignment of our
organization pursuant to the merger of WABCO and MotivePower. Within each group,
our new product development programs provide us with an array of product
upgrades that strengthen our OEM and aftermarket sales. Our products and
services, by business segment, include:

FREIGHT GROUP -- Includes products geared to the production of freight cars and
locomotives, including braking control and train coupler equipment. Revenues are
derived principally from OEM and aftermarket sales and to a lesser extent,
repairs and services. Revenues from these products, as a percentage of total net
sales, was 79%, 80% and 78% in 1999, 1998 and 1997, respectively.

Specific product lines within the Freight Group are:

 --  FREIGHT CAR -- We manufacture, sell and service air brake equipment, draft
     gears, hand brakes and slack adjusters for the OEM freight car market and
     to the aftermarket in the form of component parts and repair services. Net
     sales per typical freight car can vary considerably based upon the type and
                                        3
<PAGE>   5

     purpose of the freight platform, with articulated or intermodal cars
     generally having the highest Wabtec product content. The Company's
     traditional freight products include the ABDX Freight Brake Valve, the Mark
     Series draft gears, hand brakes and slack adjusters, and SAC-1(TM)
     Articulated Coupler.

 --  LOCOMOTIVE -- We manufacture, sell and service air brake equipment,
     traction motors, generators, alternators, turbochargers, cooling equipment,
     gearing, diesel engines, compressors, air dryers, slack adjusters, brake
     cylinders, and monitoring and control equipment for the locomotive OEM and
     aftermarket.

We also provide fleet maintenance, overhauling and remanufacturing of
locomotives and diesel engines, and manufacturing of environmentally friendly
switcher, commuter and mid-range, DC and AC traction, diesel-electric and
liquefied natural gas locomotives up to 4,000 horsepower. The Locomotive product
line also includes manufacturing and distribution of replacement, new and
remanufactured components and parts for freight and passenger railroads,
including every Class I railroad in North America, metropolitan transit and
commuter rail authorities, industrial power-related markets and, to a lesser
extent, OEMs. Wabtec provides aftermarket components for locomotives
manufactured by the Electro-Motive Division of General Motors Corporation
("EMD"), certain components for locomotives made by the GE Transportation
Systems unit of General Electric Company ("GE") and certain components for Alco
locomotives.

Wabtec believes it is the leading independent supplier in North America of many
aftermarket locomotive components.

Demand for components is influenced by rail traffic activity. As traffic
increases, the railroads seek to maximize locomotive availability and capacity,
which can increase the frequency of necessary repairs and maintenance. This
business is highly competitive, as the Company faces competition from EMD, GE
and numerous smaller, independent manufacturers and distributors. EMD and GE
accounted for virtually 100% of the new high-horsepower locomotives delivered in
the United States in the past five years and, as OEMs, are the principal
suppliers of original parts for their locomotives.

 --  ELECTRONICS -- We manufacture, sell and service high-quality electronics
     for the railroads in the form of on-board systems and braking for
     locomotives and freight cars. We are an industry leader in insulating or
     "hardening" electronic components to protect them from severe conditions,
     including extreme temperatures and high/shock vibration environments. Our
     new product development effort has focused on electronic technology for
     brakes and controls, and over the past several years, we introduced a
     number of significant new products including the EPIC(R)Electronic Brake,
     PowerLink(TM), compressor aftercoolers, Train Trax(TM), Trainlink(TM),
     Train Sentry III(R), Fuellink(TM) and Armadillo(TM).

TRANSIT GROUP -- Includes products for passenger transit vehicles (typically
subways and buses). Revenues are derived primarily from OEM and aftermarket
component part(s) sales. Revenues from these products, as a percentage of total
net sales, were 21%, 20% and 22% in 1999, 1998 and 1997, respectively.

We manufacture, sell and service electronic brake equipment, pneumatic control
equipment, air compressors, tread brakes and disc brakes, couplers, collection
equipment, overhead electrification, monitoring systems, wheels, climate control
and door equipment and other components for passenger transit vehicles. With the
1996 acquisition of Vapor, Inc., this group is a large supplier of door control
equipment for mass transit vehicles. In 1997, we received contracts valued at
$150 million to provide equipment for 1,080 passenger transit cars for the
Metropolitan Transportation Authority/New York City Transit (the "MTA").
Deliveries of equipment have begun and are expected to continue in 2000.

Substantially all of our principal passenger transit products are engineered to
customer specifications. Consequently, there is less standardization among these
products than with the Freight Group products. Because the market for OEM orders
has been at a cyclical low during the past several years, we believe the OEM
market presents an opportunity for improved growth during the next several
years.

For additional information on our business segments, see Note 16 to "Notes to
Consolidated Financial Statements" included in Part II, Item 8 of this report.

STRATEGY

We are committed to building shareholder value by capitalizing on the synergies
of our merger with MotivePower Industries and by enhancing our position as a
producer of value-added equipment for the

                                        4
<PAGE>   6

rail industry. Building on our leading market shares, strong aftermarket
presence and technological leadership, we are pursuing a strategy with five key
elements:

Expand Technology-Driven New Product Development and Product Lines

We plan to continue to emphasize research and development to create new and
improved products to increase our market share and profitability. We are
focusing on technological advances, especially in the areas of electronics,
braking products and other on-board systems, as a means of new product growth.
The Company believes that this strategy has been successfully executed by the
former Westinghouse Air Brake Company operations, and that it can improve the
ability of the former MotivePower Industries operations to be successful as
well.

Increase Repair and Upgrade Services

By continuing to leverage our broad product offering and our large installed
product base, we intend to expand our presence in the repair and upgrade
services market. We believe our services are more cost-effective than, and offer
product upgrades not available in, most independent repair shops. To capitalize
on the growing aftermarket and the railroads' desire to outsource
non-transportation functions, we are developing and marketing retrofit and
upgrade products that serve as a platform for offering additional installation,
replacement parts and repair services to customers.

Grow International Presence

We believe that international sales represent a significant opportunity for
further growth. Our net sales outside of the United States comprised
approximately 26%, 27% and 24% in 1999, 1998 and 1997, respectively (see Note 16
to "Notes to Consolidated Financial Statements" included in Part II, Item 8 of
this report). We intend to increase our existing international sales by
acquisitions, direct sales of products through our subsidiaries and licensees,
and joint ventures with railway suppliers having a strong presence in their
local markets.

Pursue Strategic Acquisitions and Alliances

We intend to pursue strategic acquisitions and alliances that expand our product
lines, increase our aftermarket business, increase international sales and
increase our technical capabilities. An integral component of our acquisition
strategy is to realize revenue growth and cost savings through the integration
of the acquired business.

Further Improve Manufacturing Efficiency and Quality

We intend to build on what we consider to be a leading position as a low-cost
producer in the industry while maintaining world-class product quality,
technology and customer responsiveness. Through the Wabtec Quality and
Performance System, we are dedicated to "lean manufacturing" principles and
continuous improvement across all phases of our business. Our QPS includes
employee-directed initiatives through Kaizen, a Japanese-developed team concept
used to continuously improve quality, lead time and productivity, and to reduce
costs. Our QPS tools also include Statistical Engineering and Value Stream
Analysis. These efforts enable us to streamline processes, improve product
quality and customer satisfaction, reduce product cycle times and respond more
rapidly to market developments. We believe our management and employees are
appropriately incentivized to carry out our strategy. Management and insiders
own approximately 25% of our Common Stock, and our employees own Common Stock
through an Employee Stock Ownership Plan ("ESOP") and other plans.

BACKLOG

The backlog as of December 31, 1999, and December 31, 1998, and the expected
year of recognition is as follows:

The Company's contracts are subject to standard industry cancellation
provisions, including cancellations on short notice or upon completion of
designated stages, including, without limitation, contracts

                                        5

relating to the MTA. Substantial scope-of-work adjustments are common. For these
and other reasons, work in the Company's backlog may be delayed or cancelled and
backlog should not be relied upon as an indicator of the Company's future
performance. The railroad industry, in general, has historically been subject to
fluctuations due to overall economic conditions and the level of use of
alternate modes of transportation. The Freight Group has significant multiple
year locomotive overhaul and fleet contracts that may provide some level of
assurance that additional component parts sales in support of overhauling
services will occur in the future.

With respect to OEM passenger transit products, there is a longer lead-time for
car deliveries and, accordingly, the Company carries a large backlog of orders.

Based upon widely available industry data concerning freight and locomotive OEM
backlog and projected 2000 deliveries (that indicate a decline from 1999
deliveries), the Company believes demand for its products will remain reasonably
strong for the foreseeable future.

ENGINEERING AND DEVELOPMENT

Consistent with its strategy of using technology to develop new products, the
Company is actively engaged in a variety of engineering and development
activities. For the fiscal years ended December 31, 1999, 1998 and 1997, the
Company incurred costs of approximately $34.5 million, $30.4 million, and $24.4
million, respectively, on product development and improvement activities
(exclusive of manufacturing support). Such expenditures represented
approximately 3.1%, 2.9%, and 2.8% of net sales for the same periods,
respectively. From time to time, the Company conducts specific research projects
in conjunction with universities, customers and other railroad product
suppliers.

The Company's engineering and development program is largely focused upon new
braking technologies, with an emphasis on the application of electronics to
traditional pneumatic equipment. Electronic actuation of braking has long been a
part of the Company's transit product line but interchangeability, connectivity
and durability have presented problems to the industry in establishing
electronics in freight railway applications. Efforts are under way to develop
the major components of both hard-wired and radio-activated braking equipment.

INTELLECTUAL PROPERTY

The Company has numerous U.S. patents, patent applications pending and
trademarks as well as foreign patents and trademarks throughout the world. The
Company also relies on a combination of trade secrets and other intellectual
property laws, nondisclosure agreements and other protective measures to
establish and protect its proprietary rights in its intellectual property.

Certain trademarks, among them the name WABCO(R), were acquired or licensed by
the Company from American Standard Inc. in 1990 at the time of the Company's
acquisition of the North American operations of the Railway Products Group of
American Standard (the "1990 Acquisition").

The Company is a party, as licensor and licensee, to a variety of license
agreements. The Company does not believe that any single license agreement,
other than the SAB License discussed in the following paragraph, is of material
importance to its business as a whole.

The Company and SAB WABCO Holdings B.V. ("SAB WABCO") entered into a license
agreement (the "SAB License") on December 31, 1993, pursuant to which SAB WABCO
granted the Company a license to the intellectual property and know-how related
to the manufacturing and marketing of certain disc brakes, tread brakes and low
noise and resilient wheel products. SAB WABCO is a Swedish corporation that was
a former affiliate of the Company, both having been owned by the same parent in
the early 1990's.

The Company is authorized to manufacture and sell the licensed products in North
America (including to OEM manufacturers located outside North America if such
licensed products are incorporated into a final product to be sold in North
America). SAB WABCO has a right of first refusal to supply the Company with
bought-in components of the licensed products on commercially competitive terms.
To the extent SAB WABCO files additional patent or trademark applications, or
develops additional know-how in connection with the licensed products, such
additional intellectual property and know-how are also subject to the SAB
License. The Company may, at its expense, request the service of SAB WABCO in
manufacturing, installing, testing and maintaining the licensed products and
providing customer support. SAB WABCO is entitled to a free, nonexclusive
license of the use of any improvements to the licensed products developed by the
Company. If any such improve-

                                        6

ments are patented by the Company, SAB WABCO has the right to request the
transfer of such patents upon payment of reasonable compensation therefor; in
such cases, the Company is entitled to a free, nonexclusive license to use the
patented product. Under the SAB license, the Company is required to pay a lump
sum fee for certain licensed products as well as royalties based on specified
percentages of sales. The SAB license expires December 31, 2003, but may be
renewed for additional one-year terms.

CUSTOMERS

A few customers within each business segment represent a significant portion of
the Company's net sales; however, no one customer represented more than 10% of
the Company's net sales in 1999. One customer represented 12% of Transit Group
sales. Nevertheless, the loss of a few key customers within the Company's
Freight and Transit Groups could have an adverse effect on the Company's
financial condition, results of operations and liquidity.

COMPETITION

The Company operates in a competitive marketplace. Price competition is strong
and the existence of cost-conscious purchasers of a limited number has
historically limited Wabtec's ability to increase prices. In addition to price,
competition is based on product performance and technological leadership,
quality, reliability of delivery and customer service and support. The Company's
principal competitors vary to some extent across its principal product lines.
However, within North America, New York Air Brake Company, a subsidiary of the
German air brake producer Knorr-Bremse AG (collectively, "NYAB/ Knorr"), is the
Company's principal overall OEM competitor along with the OEM's themselves. The
Company's competition for locomotive, freight and passenger transit service and
repair business is primarily from the railroads' and passenger transit
authorities' in-house operations, the in-house operations of EMD and GE, and
NYAB/Knorr.

EMPLOYEES

We employ approximately 6,500 employees, approximately 36% of whom were
unionized. Almost all of the employees subject to collective bargaining
agreements are within North America and these agreements are generally effective
through 2001 and 2002.

The Company considers its relations with its employees and union representation
to be good, but cannot assure that future contract negotiations will be
favorable to the Company.

REGULATION

In the course of its operations, the Company is subject to various regulations,
agencies and entities. In the United States, these include principally the
Federal Railroad Administration ("FRA") and the Association of American
Railroads ("AAR").

The FRA administers and enforces federal laws and regulations relating to
railroad safety. These regulations govern equipment and safety standards for
freight cars and other rail equipment used in interstate commerce.

The AAR promulgates a wide variety of rules and regulations governing safety and
design of equipment, relationships among railroads with respect to railcars in
interchange and other matters. The AAR also certifies railcar builders and
component manufacturers that provide equipment for use on railroads in the
United States. New products generally must undergo AAR testing and approval
processes.

As a result of these regulations and regulations in other countries in which the
Company derives its revenues, we must maintain certain certifications as a
component manufacturer and for products we sell.

consolidated financial statements included in Part II, Item 8 of this report.

(1) In 1995, the Company had Unusual Items totaling $40.8 million related to
    exiting the high-horsepower locomotive business, the impairment of the
    Mountaintop facility and the locomotive lease fleet, the disposition of one
    of the Company's Australian operations and other charges. The effect on
    diluted earnings per share was a charge of $0.58. Without the effect of this
    charge, 1995 earnings would have been $0.43 per diluted share.

(2) In 1999, the Company recorded $50.1 million, of which $43.6 million is the
    operating expense component and $5.2 million, the charge to gross profit;
    for a merger and restructuring charge pursuant to a plan that involves the
    elimination of duplicate facilities and excess capacity, operational
    realignment and related workforce reductions, and the evaluation of certain
    assets as to their perceived ongoing benefit to the Company. The effect on
    diluted earnings per share was a charge of $0.91. Without the effect of this
    charge, 1999 earnings would have been $1.74 per diluted share.

(3) In 1998, the Company sold its Argentine investment in Trenes de Buenos Aires
    S.A. and recognized an investment gain of $8.4 million. The effect on
    diluted earnings per share was a gain of $0.12. Without the effect of this
    gain, 1998 earnings would have been $1.55 per diluted share.

ITEM 7. MANAGEMENT'S DISCUSSION AND
        ANALYSIS OF FINANCIAL
        CONDITION AND RESULTS OF
        OPERATIONS

OVERVIEW

Net income in 1999 was $36.6 million, or $0.83 per diluted share, as compared to
$73.9 million or $1.67 per diluted share, in 1998. Excluding the merger and
restructuring charge discussed below, Wabtec set financial records in 1999 with
net income of $77 million, earnings per diluted share of $1.74 and net sales of
$1.1 billion. Net sales increased 8.2% in 1999 including the sales from
companies acquired in late 1998 and 1999.

Gross margin in 1999 was 29.6% compared to 29% in 1998. After excluding the cost
of sales component of the merger and restructuring charge, gross margins would
have increased to 30.1%.

Operating margins in 1999 decreased to 10.3% as compared to 14% in 1998. After
excluding the merger and restructuring charges that effect operating income,
operating margins increased to 14.7% compared to that of the prior year.

MERGER AND RESTRUCTURING PLAN

The Company announced a merger and restructuring plan that is anticipated to
yield synergies of $15 million pre-tax in 2000 and produce an ongoing annualized
benefit of $25 million, pre-tax, by year-end 2000. The Company expects the
benefits to be realized through reduced cost of sales and reduced selling,
general and administrative expenses. The merger and restructuring plan involves
the elimination of duplicate facilities and excess capacity, operational
realignment and related workforce reductions, and the evaluation of certain
assets as to their perceived ongoing benefit to the Company. The Company
estimates the charges to complete the merger and restructuring plan will total
$70 million pre-tax with approximately $50 million of the charge being expensed
in the fourth quarter of 1999. The $50 million charge was recorded as follows:
$5.2 million in cost of sales; $43.6 million as a separate line item in
operating expenses and $1.3 million ($850,000 net of tax) as an extraordinary
item. The cash and non-cash portion of the $50 million charge are estimated to
be $38 million ($29 million has been spent through the end of 1999) and $12
million, respectively. Of the $20 million charge left to be incurred, the
Company expects the majority of this charge to occur in the second and third
quarter of 2000 with the cash portion being approximately $12 million to $13
million of the charge.

The $50 million charge included the following announced actions:

 --  Costs associated with the transaction for items such as investment bankers,
     legal fees, accountant fees, SEC fees, etc.

 --  Consolidation of the corporate headquarters to Wilmerding, PA and the
     elimination of duplicate corporate functions.

 --  Closing and moving of Young Radiators' Centerville, IA plant and
     consolidating the Young administrative offices into the Company's Jackson,
     TN facility.

 --  Closing of G&G Locotronic's plant in Itasca, IL and moving its production
     into the nearby Elk Grove Village, IL facility and to San Luis Potosi,
     Mexico.

 --  Implementing a national sales force and eliminating duplicate sales
     functions.

As of December 31, 1999, $8.7 million of the $50 million merger and
restructuring-related charge was still remaining as accrued on the balance
sheet. The accrual on the balance sheet is discussed in greater detail in Note
19 to "Notes to Consolidated Financial Statements" included in Part II, Item 8
of this report.

</TABLE>

                             1999 COMPARED TO 1998

Net sales increased 8.2% to $1.1 billion in 1999 from $1 billion in 1998. The
increase was driven by acquisitions, primarily within the Freight Group, which
contributed $113 million of sales in 1999. Incremental revenue from the
acquisitions, along with an increase in Transit Group sales, were partially
offset by a slowdown in the locomotive overhaul market and in U.S. freight car
deliveries which decreased slightly in 1999 to 74,223 from 75,685 in 1998. In
2000, the Company expects the OEM freight car and locomotive industries to
deliver approximately 50,000 and 1,100 new freight cars and locomotives,
respectively.

Cost of sales increased 7.3% to $789.1 million in 1999 from $735.6 million in
1998. Gross margin increased to 29.6% as compared to 29% in 1998. After
excluding the cost of sales component of the merger and restructuring charge,
gross margin would have increased to 30.1%. The increase is attributed to volume
and a favorable product mix in the Freight Group component companies, and from
the increased volume of the Transit Group.

Selling, general and administrative expenses increased 7.4% to $122 million from
$113.6 million in 1998. Cost reductions and lower incentive-related expenses
were offset by the operating expenses of acquired companies ($18 million).

Engineering expenses increased 13.4% to $34.5 million from $30.4 million
primarily as a result of the Rockwell acquisition in October 1998 and new
product development efforts.

Amortization expense increased 38% to $15.8 million in 1999 from $11.5 million
in 1998. The increase is primarily attributable to the acquisitions made late in
1998 (Rockwell Railroad Electronics division (Rockwell), October 1998 and Young
Radiator (Young), November 1998) and the acquisitions made early in 1999 (G&G
Locotronics and Q-Tron in January 1999 and AGC Technologies in February 1999).

Income from operations totaled $116 million in 1999 compared with $145 million
in 1998 with operating margins of 10.3% and 14%, respectively. After excluding
the operating expense component of the merger and restructuring charge,
operating income would have been $164.9 million and operating mar-

                                       14
<PAGE>   16

gins as a percentage of sales for 1999 increased to 14.7%, slightly higher than
14% in the prior year. Higher adjusted operating income resulted from higher
sales volume and related gross profit. Favorable aftermarket sales volume at
relatively strong operating margins in the Transit Group and the component
companies in the Freight Group were the primary reasons for the increase in
operating income (see Note 16 to "Notes to Consolidated Financial Statements"
included in Part II, Item 8 of this report).

Interest expense increased 19.7% to $44.4 million in 1999 from $37.1 million in
1998. Debt, net of cash and equivalents, was $562 million as of December 31,
1999 versus $565 million as of December 31, 1998. The increase in interest
expense, even though the net debt balance decreased, is due to Wabtec carrying a
higher average debt balance in 1999 as a result of the late 1998 acquisitions
(Rockwell -- $80 million and Young -- $68 million) and the 1999 acquisitions of
G&G Locotronics, Q-Tron and AGC Technologies ($32 million). Wabtec also funded
cash transaction costs associated with the merger, which totaled about $29
million.

Investment income -- Argentina represents income recognized related to an
investment in Argentina which was sold in 1998 for cash and a secured note
receivable.

Other expense of $90,000 was recorded in 1999 versus other income of $3 million
in 1998. The fluctuation is due to foreign exchange gains/losses as a foreign
exchange loss virtually offsetting in 1999 compared to a foreign exchange gain
of $2 million in 1998.

The Company recorded income tax expense of $33.6 million as compared to $42.1
million in 1998. The effective tax rate for 1999 was 46.9% as compared to 34.7%
in 1998. After excluding the assumed tax benefit component of the merger and
restructuring charge, Wabtec incurred income tax expense of $43 million in 1999,
or an effective tax rate of 35.6%, as compared to 34.7% in 1998. The 1998 rate
was lower due to a non-recurring deferred tax liability reversal. Wabtec expects
the ongoing rate to be approximately 36%. The Company has consolidated Mexican
and United States federal net operating loss carryforwards of $5 million and $19
million expiring at various times through year 2005 and 2010, respectively.

In 1999, a $469,000 extraordinary loss, net of tax, was incurred on the
extinguishment of certain term debt as well as an $850,000 extraordinary loss,
net of tax, for the write-off of deferred financing fees on the refinancing of
the Company's principal credit facility in November 1999 in connection with the
merger. In 1998, Wabtec incurred a $5.3 million extraordinary loss, net of tax,
related to amending certain credit facilities.

                             1998 COMPARED TO 1997

Net sales increased 19% to $1 billion in 1998 from $870 million in 1997.
Incremental revenues from acquisitions contributed $85 million of the increase.
Increased sales in the Freight Group were also positively impacted by OEM
freight car deliveries increasing to 75,685 deliveries in 1998 from 50,396
deliveries in 1997, and an increase in locomotive overhauls and freight car work
in the United States and Mexico in 1998.

Cost of sales increased 20.3% to $735.6 million in 1998 from $611.9 million in
1997. Gross margin decreased to 29% in 1998 from 29.7% in 1997. The primary
reason for the decrease was because the incremental gross margin from the 1998
acquisitions was at a lower margin than the other subsidiaries.

Selling, general and administrative expenses increased 16% to $113.6 million in
1998 from $97.9 million in 1997. Operating expenses of acquisitions accounted
for $14 million of the increase while costs associated with preparing for year
2000 compliance were about $3 million.

Engineering expenses increased 24.8% to $30.4 million in 1998 from $24.4 million
in 1997. The increase was attributed to new product development in 1998.

Income from operations totaled $145 million in 1998 compared with $124.6 million
in 1997. Higher operating income resulted from higher sales volume and related
higher gross profit. As a percentage of sales, 1998 operating income was 14% and
is slightly lower than 14.3% in the prior year. Favorable OEM sales volume at
generally weaker operating margins in both the Freight and Transit Groups was
the primary reason (see Note 16 to "Notes to Consolidated Financial Statements"
included in Part II, Item 8 of this report).

Interest expense increased 6.4% to $37.1 million in 1998 from $34.9 million in
1997. Debt, net of cash and equivalents was $565 million as of December 31, 1998
versus $398 million as of December 31, 1997. The increase is attributed to the
late 1998 acquisitions of Rockwell and Young.

Investment income--Argentina represents income recognized related to an
investment in Argentina and was $10 million in 1998 versus $2 million in 1997.
The increase is due to Wabtec selling its investment in Argentina for cash and a
secured note receivable during 1998.

Other income of $3 million was recorded in 1998 compared to other income of
$875,000 in 1997. The fluctuation is primarily due to a foreign exchange gain of
$2 million being recorded in 1998.

The Company recorded income tax expense of $42.1 million in 1998 versus $35
million in 1997. The effective income tax rate was 34.7% in 1998 compared to
37.8% in 1997. The decrease in the effective tax rate was primarily the result
of the utilization of a Foreign Sales Corporation and a non-recurring reversal
of a deferred tax liability in 1998.

In 1998, Wabtec incurred a $5.3 million extraordinary loss, net of tax, related
to the amending of certain credit facilities in the first and second quarter of
1998, and the repayment of our higher-rate Mexican facility in the fourth
quarter of 1998.

LIQUIDITY AND CAPITAL RESOURCES

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

</TABLE>

Operating cash flow in 1999 was $77.4 million as compared to $73.4 million in
the same period a year ago. During 1999, cash outlays for merger and
restructuring activities were approximately $29 million and are reported as a
reduction to cash provided by operating activities. Excluding these cash
outlays, cash provided by operating activities would have been approximately
$106.7 million, compared to $73.4 million in 1998. This increase was primarily
the result of improved working capital management. However, within the Freight
Group, inventory levels increased due to strategic purchases of locomotive and
parts cores used in exchange and overhaul programs and additionally within the
Transit Group, production continues for anticipated future product deliveries
related to the Metropolitan Transit Authority/New York City Transit project.
Adjusted EBITDA, excluding the merger and restructuring charge, would have been
$207 million in 1999 as compared to $182 million in 1998.

Cash used for investing activities declined in 1999 to $66.4 million from $243.8
million a year ago. In 1999, 1998 and 1997, the Company used $32.2 million,
$180.2 million and $24.8 million, respectively, for certain business
acquisitions. Capital expenditures were $30.8 million, $57.8 million and $44.2
million in 1999, 1998 and 1997, respectively. The majority of capital
expenditures for these periods relates to upgrades to existing equipment,
replacement of existing equipment and purchases of new equipment due to
expansion of Wabtec's operations, where the Company believes overall cost
savings can be achieved through increasing efficiencies. The Company expects
2000 capital expenditures for equipment purchased for similar purposes to
approximate $40-$45 million.

Cash used for financing activities was $11.7 million in 1999 versus cash
provided by financing activities of $161.9 million in 1998. As described below,
the Company refinanced the pre-existing credit facilities of WABCO and
MotivePower immediately following the merger in November 1999. Additionally, the
Company issued $75 million of senior notes in the first quarter of 1999 and used
the proceeds to repay amounts outstanding on certain unsecured bank term debt
and repaid a portion of the Company's previous revolving credit facility.
Historically, the Company has financed the purchase of significant businesses
utilizing the amounts available under its credit facilities.

The Company estimates the charges to complete the merger and restructuring plan
will total $70 million pre-tax with approximately $50 million of the charge
being expensed in the fourth quarter of 1999. The cash and non-cash portion of
the 1999 $50 million charge were $38 million and $12 million, respectively. Of
the $20 million charge yet to be incurred, the Company expects the majority of
this charge to occur in the second and third quarter of 2000 with the

                                       16
<PAGE>   18

cash portion being approximately $12-$13 million of the charge.

Based on anticipated cash flow provided by operations, forecasted results and
credit available under the credit agreement, the Company believes it will be
able to make planned capital expenditures and required debt payments over the
next twelve months.

The following table sets forth the Company's outstanding indebtedness and
average interest rates at December 31, 1999. The revolving credit note and other
term loan interest rates are variable and dependent on market conditions.
Interest on the Pulse note can vary with prime.

</TABLE>

Credit Agreement

In November 1999, in connection with the merger, WABCO terminated its then
existing credit agreement and refinanced the then existing MotivePower credit
agreement with a consortium of commercial banks. The credit agreement provides
for a $275 million five-year revolving credit facility and a 364-day $275
million convertible revolving credit facility. At December 31, 1999, the Company
had available borrowing capacity, net of letters of credit, of approximately
$158 million.

Under the credit agreement, the Company may elect a base rate, an interest rate
based on the London Interbank Offered Rates of Interest ("LIBOR"), a cost of
funds rate and a bid rate. The base rate is the greater of ABN AMRO Bank N.V.'s
prime rate or the federal funds effective rate plus 0.5% per annum. The LIBOR
rate is based on LIBOR plus a margin that ranges from 62.5 to 175 basis points
depending on the Company's consolidated total indebtedness to cash flow ratios.
The cost of funds rate is a fluctuating interest rate based on ABN AMRO Bank
N.V.'s then cost of funds. Under the bid rate option, any participating bank may
propose the interest rate at which it will lend funds, which rate may either be
a fixed rate or a floating rate based on LIBOR.

The credit agreement limits the Company's ability to declare or pay cash
dividends and prohibits the Company from declaring or making other
distributions, subject to certain exceptions, whether in cash, property,
securities or a combination thereof. One exception to this restriction is that
the Company may make repurchases and redemptions, and pay dividends (net of
dividends on unallocated shares of Common Stock of the Company that are returned
to the Company) in an aggregate amount not to exceed 50% of the Company's
accumulated consolidated net income for that fiscal year. The credit agreement
contains various other covenants and restrictions including, without limitation,
the following: a limitation on the incurrence of additional indebtedness; a
limitation on mergers, consolidations and sales of assets and acquisitions; a
limitation on liens; a limitation on sale and leasebacks; a limitation on
investments, loans and advances; a limitation on certain debt payments; a
limitation on capital expenditures; a minimum interest expense coverage ratio;
and a maximum debt to cash flow ratio.

The credit agreement contains customary events of default, including payment
defaults, failure of representations or warranties to be true in any material
respect, covenant defaults, defaults with respect to other indebtedness of the
Company, bankruptcy, certain judgments against the Company, ERISA defaults and
"change of control" of the Company.

Credit agreement borrowings bear variable interest rates indexed to common
indexes such as LIBOR. The weighted-average contractual interest rate on credit
agreement borrowings was 7.36% at December 31, 1999. To reduce the impact of
interest rate changes on a portion of this variable-rate debt, the Company
entered into interest rate swaps which effectively convert a portion of the debt
from variable to fixed-rate borrowings during the term of the swap contracts. On
December 31, 1999, the notional value of interest rate swaps outstanding totaled
$50 million and effectively changed the Company's interest rate from a variable
rate to a fixed rate of 7.33%. The interest rate swap agreements mature in 2000
and

                                       17
<PAGE>   19

2001. The Company is exposed to credit risk in the event of nonperformance by
the counterparties. However, since only the cash interest payments are
exchanged, exposure is significantly less than the notional amount. The
counterparties are large financial institutions and the Company does not
anticipate nonperformance.

9 3/8% Senior Notes Due June 2005

In June 1995, the Company issued $100 million of 9 3/8% Senior Notes due in 2005
(the "1995 Notes"). In January 1999, the Company issued an additional $75
million of 9 3/8% Senior Notes which are due in 2005 (the "1999 Notes"; the 1995
Notes and the 1999 Notes are collectively, the "Notes"). The 1999 Notes were
issued at a premium resulting in an effective rate of 8.5%. The terms of the
1995 Notes and the 1999 Notes are substantially the same, and the 1995 Notes and
the 1999 Notes were issued pursuant to indentures that are substantially the
same. The issuance of the 1999 Notes improved the Company's financial liquidity
by i) using a portion of the proceeds to repay $30 million of debt associated
with the Rockwell acquisition that bore interest at 9.56%; ii) using a portion
of the proceeds to repay variable-rate revolving credit borrowings thereby
increasing amounts available under the revolving credit facility; and iii)
repaying the remaining unpaid principal of $10.2 million from the Comet
acquisition.

The Notes are senior unsecured obligations of the Company and rank pari passu in
right of payment with all existing and future indebtedness under (i) capitalized
lease obligations, (ii) the Credit Agreement, (iii) indebtedness of the Company
for money borrowed and (iv) indebtedness evidenced by notes, debentures, bonds
or other similar instruments for the payment of which the Company is responsible
or liable unless, in the case of clause (iii) or (iv), in the instrument
creating or evidencing the same or pursuant to which the same is outstanding, it
is provided that such obligations are subordinate in right of payment to the
Notes.

Unsecured Credit Facility

In October 1998, the Company obtained a $30 million unsecured credit facility
from a group of commercial banks for the purpose of financing the Rockwell
acquisition. In January 1999, this facility was repaid with proceeds of the 1999
Notes offering.

Pulse Note

As partial payment for the Pulse acquisition, the Company issued a $17 million
note due January 31, 2004, with interest at 9.5%. In January 2000, this note was
repaid with our revolving credit facility.

Comet Notes

In connection with the Comet acquisition, the Company issued notes totaling
$12.2 million, of which unsecured notes totaling $6.2 million were delivered by
the Company and a note in the amount of $6 million was delivered by a subsidiary
of the Company and secured by the acquired assets. These notes were repaid in
January 1999 with proceeds of the 1999 Notes offering.

Industrial Revenue Bond

In July 1998, a subsidiary of the Company entered into a 10-year $7.5 million
debt obligation that bears an interest rate of 5.5% to provide financing for the
purchase of a building used in the Company's operations.

Principal repayments of outstanding loan balances are due at various intervals
until maturity. See Note 6 to "Notes to Consolidated Financial Statements"
included in Part II, Item 8 of this report.

ESOP

In connection with the establishment of the ESOP in January 1995, the Company
made a $140 million loan to the ESOP (the "ESOP Loan"), which was used to
purchase 9,336,000 shares of the Company's outstanding common stock. The ESOP
Loan had an original term of 50 years, with annual payments of principal and
interest of approximately $12 million. The ESOP Loan bears interest at 8.5% per
annum. The ESOP will repay the ESOP Loan using contributions from the Company.
The Company is obligated to contribute amounts sufficient to repay the ESOP
Loan. The net effect of the ESOP is that the Company's Common Stock is allocated
to employees in lieu of a retirement plan that was previously a cash-based
defined benefit plan and, accordingly, results in reduced annual cash outlays by
an estimated $3 million to $4 million.

Management believes, based upon current levels of operations and forecasted
earnings, that cash flow from operations, together with borrowings under the
credit agreement, will be adequate to make payments of principal and interest on
debt, including the Notes,

                                       18
<PAGE>   20

to make required contributions to the ESOP, to permit anticipated capital
expenditures, and to fund working capital requirements and other cash needs for
the foreseeable future, including 2001. Overall, increases in financial
liquidity was primarily the result of changing the base available for borrowing
under the November 1999 refinanced Credit Agreement. The issuance of 1999 Notes
also increased the Company's liquidity by reducing its outstanding revolving
credit borrowings and thereby increasing its available borrowing capacity.

Nevertheless, the Company will remain leveraged to a significant extent and its
debt service obligations will continue to be substantial. The debt of the
Company requires the dedication of a substantial portion of future cash flows to
the payment of principal and interest on indebtedness, thereby reducing funds
available for capital expenditures and future business opportunities that the
Company believes are available. Cash flow and liquidity will be sufficient to
meet its debt service requirements. If the Company's sources of funds were to
fail to satisfy the Company's cash requirements, the Company may need to
refinance its existing debt or obtain additional financing. There is no
assurance that such new financing alternatives would be available, and, in any
case, such new financing, if available, would be expected to be more costly and
burdensome than the debt agreements currently in place.

EFFECTS OF YEAR 2000

The Company has information system improvement initiatives in process that
include both new computer hardware and software applications. The new system is
substantially operational and is Year 2000 compliant. The cost of the project
will be approximately $17 million with the majority of costs previously
incurred.

Based on information available to date, Wabtec has not experienced any
significant events attributable to Year 2000 issues. The Company will continue
to monitor for potential issues at Wabtec, its customers and suppliers, in order
to permit a rapid response should any issues arise. The impact of Year 2000
issues will continue to depend on the way the issues have been addressed by
third parties that provide products and services to us. The Company believes
that if any Year 2000 issues were to arise, they would not have a significant
impact on its operations.

Wabtec does not expect to incur significant direct costs related to the Year
2000 issue during the current year.

EFFECTS OF INFLATION; SEASONALITY

General price inflation has not had a material impact on the Company's results
of operations. Some of the Company's labor contracts contain negotiated salary
and benefit increases and others contain cost of living adjustment clauses,
which would cause the Company's cost automatically to increase if inflation were
to become significant. The Company's business is not seasonal, although the
third quarter results may be impacted by vacation and plant shut-downs at
several of its major customers during this period.

CONVERSION TO THE EURO CURRENCY

On January 1, 1999, certain members of the European Union established fixed
conversion rates between their existing currencies and the European Union's
common currency (the "Euro"). The Company conducts business in member countries.
The transition period for the introduction of the Euro is from January 1, 1999
through June 30, 2002. The Company is assessing the issues involved with the
introduction of the Euro; however, it does not expect conversion to the Euro to
have a material impact on its operations or financial results.

RECENT ACCOUNTING PRONOUNCEMENTS

Derivative Instruments and Hedging Activities In June 1998, Statement of
Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activity", was issued. SFAS No. 133, as amended by SFAS
No. 137, "Accounting for Derivative Instruments and Hedging Activities -
Deferral of Effective Date of FASB Statement No. 133 - an amendment of FASB
Statement No. 133" is effective for financial statements for fiscal quarters of
fiscal years beginning after June 15, 2000. The Company has not yet determined
the effect of this standard on its financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE RISK

In the ordinary course of business, Wabtec is exposed to risks that increases in
interest rates may adversely affect funding costs associated with $320 million
of variable-rate debt (including the effects of interest rate swaps), which
represents 56% of total long-term debt at December 31, 1999. Management has
entered into pay-fixed, receive-variable interest rate swap contracts that
partially mitigate the impact of variable-rate debt interest rate increases (see
Note 6 to "Notes to Consolidated Financial Statements" included in Part II, Item
8 of this report). At December 31, 1999, an instantaneous 100 basis point
increase in interest rates would reduce the Company's annual earnings by $2.1
million, assuming no additional intervention strategies by management.

FOREIGN CURRENCY EXCHANGE RISK

The Company routinely enters into several types of financial instruments for the
purpose of managing its exposure to foreign currency exchange rate fluctuations
in countries in which the Company has significant operations. As of December 31,
1999, the Company had no such instruments outstanding.

                                       20
<PAGE>   22

Wabtec is also subject to certain risks associated with changes in foreign
currency exchange rates to the extent its operations are conducted in currencies
other than the U.S. dollar. At December 31, 1999, approximately 74% of Wabtec's
net sales are in the United States, 9% in Canada, 7% in Mexico, and 10% in other
international locations, primarily Europe. (See Note 16 to "Notes to
Consolidated Financial Statements" included in Part II, Item 8 of this report).
At December 31, 1999, the Company does not believe changes in foreign currency
exchange rates represent a material risk to results of operations, financial
position, or liquidity.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORPORATION:

We have audited the accompanying consolidated balance sheets of Westinghouse Air
Brake Technologies Corporation (a Delaware corporation) and subsidiaries as of
December 31, 1999 and 1998, and the related consolidated statements of
operations, shareholders' equity and cashflows for each of the three years in
the period ended December 31, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits. For the years ended
December 31, 1998 and 1997, we did not audit the consolidated financial
statements of MotivePower Industries, Inc., a company acquired during 1999 in a
transaction accounted for as a pooling-of-interests, as discussed in Note 4.
Such statements are included in the consolidated financial statements of
Westinghouse Air Brake Technologies Corporation and reflect total assets and
total revenues of 38 percent and 35 percent in 1998, and 41 percent and 35
percent in 1997, respectively, of the related consolidated totals. Those
statements were audited by other auditors whose report has been furnished to us
and our opinion, insofar as it relates to amounts included for MotivePower
Industries, Inc, is based solely upon the report of the other auditors.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits and the report of other auditors
provide a reasonable basis for our opinion.

In our opinion, based on our audits and the report of the other auditors, the
financial statements referred to above present fairly, in all material respects,
the financial position of Westinghouse Air Brake Technologies Corporation and
subsidiaries as of December 31, 1999 and 1998, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1999 in conformity with accounting principles generally accepted in
the United States.

responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing

material respects, the financial position of MotivePower Industries, Inc. and

                WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS

Westinghouse Air Brake Technologies Corporation (the "Company") is one of North
America's largest manufacturers of value-added equipment for locomotives,
railway freight cars and passenger transit vehicles. The Company was formed in
November 1999 from the merger of Westinghouse Air Brake Company and MotivePower
Industries, Inc. Our major products are intended to enhance safety, improve
productivity and reduce maintenance costs for our customers. Our major product
offerings include electronic controls and monitors, air brakes, traction motors,
cooling equipment, turbochargers, low-horsepower locomotives, couplers, door
controls, draft gears and brake shoes. We aggressively pursue technological
advances with respect to both new product development and product enhancements.
The Company has its headquarters in Wilmerding, Pennsylvania and has
approximately 6,500 employees at facilities throughout the world.

A portion of the Company's Freight Group's operations and revenue base is
generally dependent on the capital replacement cycles for locomotives and
freight cars of the large North American-based railroad companies. The Company's
Passenger Transit Group's operations are dependent on the budgeting and
expenditure appropriation process of federal, state and local governmental units
for mass transit needs established by public policy.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the
accounts of the Company and its majority owned subsidiaries. Such statements
have been prepared in accordance with generally accepted accounting principles.
Sales between the subsidiaries are billed at prices consistent with sales to
third parties and are eliminated in consolidation. All prior period financial
statements and footnote disclosures have been restated in accordance with
Accounting Principles Board Number 16 "Business Combinations" related to the
merger between WABCO and MotivePower accounted for as a pooling-of-interests
(See Note 4).

Certain prior year amounts have been reclassified, where necessary, to conform
to the current year presentation

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

INVENTORIES Inventories are stated at the lower of cost or market. Cost is
determined under the first-in, first-out (FIFO) method. Inventory costs include
material, labor and overhead. Cores inventory is defined as inventory units
designated for unit exchange programs. The components of inventory, net of
reserves, were:

     Total inventory      $211,396   $196,553

</TABLE>

In conjunction with the merger between WABCO and MotivePower, companies that
previously utilized the last-in first-out method in determining inventory cost
adopted the FIFO method. The effect on the current year consolidated financial
statements was not significant to the consolidated financial statements taken as
a whole.

PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment additions are stated
at cost. Expenditures for renewals and betterments are capitalized. Expenditures
for ordinary maintenance and repairs are expensed as incurred. The Company
provides for book depreciation principally on the straight-line method over the
following estimated useful lives of plant, property and equipment.

</TABLE>

INTANGIBLE ASSETS Goodwill is amortized on a straight-line basis over 40 years.
Other intangibles are amortized on a straight-line basis over their estimated
economic lives. Goodwill and other intangible assets, including patents and
tradenames, are periodically reviewed for impairment based on an assessment of
future operations (see Note 5).

REVENUE RECOGNITION Revenue is recognized when products have been shipped to the
respective customers and the price for the product has been determined.

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

Costs and estimated earnings in excess of billings ("underbillings") and
billings in excess of costs and estimated earnings ("overbillings") on the
contract in progress are recorded on the balance sheet and are classified as
non-current (see Note 20).

STOCK-BASED COMPENSATION The Company accounts for stock-based compensation,
including stock options and employee stock purchases, under APB Opinion No. 25,
"Accounting for Stock Issued to Employees" (see Note 11 for related pro forma
disclosures).

RESEARCH AND DEVELOPMENT Research and development costs are charged to expense
as incurred. For the years ended December 31, 1999, 1998 and 1997, the Company
incurred costs of approximately $34.5 million, $30.4 million, and $24.4 million,
respectively.

WARRANTY COSTS Warranty costs are accrued based on management's estimates of
repair or upgrade costs per unit and historical experience. In recent years, the
Company has introduced several new products. The Company does not have the same
level of historical warranty experience for these new products as it does for
its continuing products. Therefore, warranty reserves have been established for
these new products based upon management's estimates. Actual future results may
vary from such estimates. Warranty expense was $10.8 million, $14 million and
$14.1 million for 1999, 1998 and 1997, respectively. Warranty reserves were
$26.8 million and $23 million at December 31, 1999 and 1998, respectively.

FINANCIAL DERIVATIVES The Company periodically enters into interest rate swap
agreements to reduce the impact of interest rate changes on its variable rate
borrowings. Interest rate swaps are agreements with a counterparty to exchange
periodic interest payments (such as pay fixed, receive variable) calculated on a
notional principal amount. The interest rate differential to be paid or received
is accrued to interest expense (see Notes 6 and 17).

In addition, the Company periodically enters into foreign exchange forward
contracts. These contracts are legal agreements between two parties to purchase
and sell a foreign currency for a specified price at the contract date, with
delivery and settlement in the future. The Company uses such contracts to hedge
the risk of foreign currency exchange rates associated with certain assets and
obligations. Changes in the market value of the forward contracts are recognized
in income when the related changes in the price of the hedged item are
recognized.

INCOME TAXES Income taxes are accounted for under the liability method. Deferred
tax assets and liabilities are determined based on differences between financial
reporting and tax bases of assets and liabilities and are measured using the
enacted tax rates and laws that will be in effect when the differences are
expected to reverse. The provision for income taxes includes federal, state and
foreign income taxes (see Note 9).

FOREIGN CURRENCY TRANSLATION Assets and liabilities of foreign subsidiaries,
except for the Company's Mexican operations whose functional currency is the
U.S. Dollar, are translated at the rate of exchange in effect on the balance
sheet date while income and

                                       33
<PAGE>   35

expenses are translated at the average rates of exchange prevailing during the
year. Foreign currency gains and losses resulting from transactions, and the
translation of financial statements are recorded in the Company's consolidated
financial statements based upon the provisions of Statement of Financial
Accounting Standards ("SFAS") No. 52, "Foreign Currency Translation." The
effects of currency exchange rate changes on intercompany transactions of a
long-term investment nature are accumulated and carried as a component of
shareholders' equity. The effects of currency exchange rate changes on
intercompany transactions that are non U.S. dollar amounts are charged or
credited to earnings.

EARNINGS PER SHARE Basic earnings per common share are computed by dividing net
income applicable to common shareholders by the weighted-average number of
shares of common stock outstanding during the year. Diluted earnings per common
share are computed by dividing net income applicable to common shareholders by
the weighted average number of shares of common stock outstanding adjusted for
the assumed conversion of all dilutive securities (such as employee stock
options). See Note 10.

OTHER COMPREHENSIVE INCOME In 1998, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive Income" which
established standards for reporting and displaying comprehensive income and its
components in financial statements. Comprehensive income is defined as net
income and all other nonowner changes in shareholders' equity. The Company's
accumulated other comprehensive income (loss) consists entirely of foreign
currency translation adjustments.

SIGNIFICANT CUSTOMERS AND CONCENTRATIONS OF CREDIT RISK The Company's trade
receivables are primarily from rail and transit industry original equipment
manufacturers, Class I railroads, and railroad carriers and commercial companies
that utilize rail cars in their operations, such as utility and chemical
companies. No one customer accounted for more than 10% of the Company's
consolidated net sales in 1999, 1998 or 1997. The allowance for doubtful
accounts was $4 million and $3.5 million as of December 31, 1999 and 1998,
respectively.

EMPLOYEES As of December 31, 1999, approximately 36% of the Company's workforce
was covered by collective bargaining agreements. These agreements are generally
effective through 2001 and 2002.

DEFERRED COMPENSATION AGREEMENTS In May 1998, a consensus on Emerging Issues
Task Force Issue No. 97-14, "Accounting for Deferred Compensation Arrangements
Where Amounts Earned Are Held in a Rabbi Trust and Invested" ("EITF 97-14"), was
issued. The adoption of EITF 97-14 required the Company to record as treasury
stock the historical value of the Company's stock maintained in its deferred
compensation plans.

RECENT ACCOUNTING PRONOUNCEMENTS In June 1998, Statement of Financial Accounting
Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging
Activity", was issued. SFAS No. 133, as amended by SFAS No. 137, "Accounting for
Derivative Instruments and Hedging Activities -- Deferral of Effective Date of
FASB Statement No. 133 -- an amendment of FASB Statement No. 133" is effective
for financial statements for fiscal quarters of fiscal years beginning after
June 15, 2000. The Company has not yet determined the effect of this standard on
its financial statements.

4. MERGERS AND ACQUISITIONS

On November 19, 1999, WABCO completed its merger with MotivePower Industries,
Inc. a leading manufacturer and supplier of locomotive components, fleet
overhauls and related services. The Company issued approximately 18 million
shares of the Company's Common Stock to former MotivePower shareholders and
reserved for the contingent exercise of stock options approximately 2 million
shares, valued at approximately $354 million in a transaction that was accounted
for by the pooling-of-interests accounting method. Accordingly, the consolidated
financial statements have been restated giving effect to this transaction as if
it had occurred as of the beginning of the earliest period presented.

The combined results of the Company and separate results of WABCO and
MotivePower for the periods preceding the merger are as follows:

During 1999, the Company completed the following acquisitions:

 i) In January 1999, the Company acquired certain assets of G&G Locotronics, a
    privately held designer of high voltage electrical cabinets and control
    stands for locomotives, for total consideration of $17.8 million. In 1998,
    G&G Locotronics had sales of approximately $22 million.

 ii) In January 1999, the Company acquired 100% of the Common Stock of Q-Tron,
     Ltd., a privately held designer and manufacturer of locomotive electronics
     equipment, for total consideration of $14.9 million. In 1998, Q-Tron had
     sales of $10 million.

iii) In February 1999, the Company acquired the mass transit electrical inverter
     and converter product line of AGC System & Technologies, Inc. of Canada for
     approximately $960,000.

The 1999 acquisitions were accounted for under the purchase method. Accordingly,
the results of operations of the applicable acquisition are included in the
Company's financial statements prospectively from the acquisition date. The
excess of the purchase price over the fair value of identifiable net assets of
$25 million was allocated to goodwill and is being amortized on a straight-line
basis over 40 years.

On October 5, 1998, the Company purchased the railway electronics business,
Rockwell Railroad Electronics, (Rockwell) of Rockwell Collins, Inc., a wholly
owned subsidiary of Rockwell International Corporation, for $80 million in cash.
Rockwell was a manufacturer and supplier of mobile electronics (display and
positioning equipment), data communications, and electronic braking equipment
for the railroad industry. The acquisition has been accounted for by the
purchase method of accounting, and accordingly, the results of operations of
Rockwell have been included in the Company's consolidated financial statements
from the date of acquisition. The $70 million excess of the purchase price over
the fair value of the net identifiable assets acquired has been recorded as
goodwill and is being amortized on a straight-line basis over 40 years.

On November 18, 1998, the Company acquired 100% of the common stock of Young
Radiator Company, a manufacturer of radiators, air coolers and heat exchange
equipment for rail and industrial power-related markets, for $67.7 million, net
of cash and marketable securities acquired. The acquisition has been accounted
for by the purchase method of accounting, and accordingly, the results of
operations of Young have been included in the Company's consolidated financial
statements from the date of acquisition. The $43 million excess of the purchase
price over the fair value of the net identifiable assets acquired has been
recorded as goodwill and is being amortized on a straight-line basis over 40
years.

The following unaudited pro forma results of operations, including the effects
of pro forma adjustments related to the acquisition of Rockwell and Young have
been prepared as if these transactions occurred at the beginning of 1997:

operations for any future period, and does not reflect anticipated cost savings
through the combination of these operations.

Credit Agreement

In November 1999, in connection with the merger, WABCO terminated its then
existing credit agreement and refinanced the then existing MotivePower credit
agreement with a consortium of commercial banks. The credit agreement provides
for a $275 million five-year revolving loan and a 364-day $275 million
convertible revolving credit facility. In connection with the establishment of
the two new revolving facilities, the Company wrote off previously deferred
financing costs of approximately $850,000, net of tax ($.02 per diluted share),
which has been reported as an extraordinary item in the accompanying financial
statements. At December 31, 1999, the Company had available borrowing capacity,
net of letters of credit, of approximately $158 million.

Under the credit agreement, the Company may elect a base rate, an interest rate
based on the London Interbank Offered Rates of Interest ("LIBOR"), a cost of
funds rate and a bid rate. The base rate is the greater of ABN AMRO Bank N.V.'s
prime rate or the federal funds effective rate plus 0.5% per annum. The LIBOR
rate is based on LIBOR plus a margin that ranges from 62.5 to 175 basis points
depending on the Company's consolidated total indebtedness to cash flow ratios.
The cost of funds rate is a fluctuating interest rate based on ABN AMRO Bank
N.V.'s then cost of funds. Under the bid rate option, any participating bank may
propose the interest rate at which it will lend funds, which rate may either be
a fixed rate or a floating rate based on LIBOR.

The credit agreement limits the Company's ability to declare or pay cash
dividends and prohibits the Company from declaring or making other
distributions, subject to certain exceptions, whether in cash, property,
securities or a combination thereof. One exception to this restriction is that
the Company may make repurchases and redemptions and pay dividends (net of
dividends on unallocated shares of Common Stock of the Company that are returned
to the Company) in aggregate amount not to exceed 50% of the Company's
accumulated consolidated net income for that fiscal year. The credit agreement
contains various other covenants and restrictions including, without limitation,
the following: a limitation on the incurrence of additional indebtedness; a
limitation on mergers, consolidations and sales of assets and acquisitions; a
limitation on liens; a limitation on sale and leasebacks; a limitation on
investments, loans and advances; a limitation on certain debt payments; a
limitation on capital expenditures; a minimum interest expense coverage ratio;
and a maximum debt to cash flow ratio.

The credit agreement contains customary events of default, including payment
defaults, failure of representations or warranties to be true in any material
respect, covenant defaults, defaults with respect to other indebtedness of the
Company, bankruptcy, certain judgments against the Company, ERISA defaults and
"change of control" of the Company.

Credit agreement borrowings bear variable interest rates indexed to common
indexes such as LIBOR. The weighted-average contractual interest rate on

                                       37
<PAGE>   39

credit agreement borrowings was 7.36% at December 31, 1999. To reduce the impact
of interest rate changes on a portion of this variable-rate debt, the Company
has entered into interest rate swaps which effectively convert a portion of the
debt from variable to fixed-rate borrowings during the term of the swap
contracts. On December 31, 1999, the notional value of interest rate swaps
outstanding totaled $50 million and effectively changed the Company's interest
rate from a variable rate to a fixed rate of 7.33%. The interest rate swap
agreements mature in 2000 and 2001. The Company is exposed to credit risk in the
event of nonperformance by the counterparties. However, since only the cash
interest payments are exchanged, exposure is significantly less than the
notional amount. The counterparties are large financial institutions and the
Company does not anticipate nonperformance.

9 3/8% Senior Notes Due June 2005

In June 1995, the Company issued $100 million of 9 3/8% Senior Notes due in 2005
(the "1995 Notes"). In January 1999, the Company issued an additional $75
million of 9 3/8% Senior Notes which are due in 2005 (the "1999 Notes"; the 1995
Notes and the 1999 Notes are collectively, the "Notes"). The 1999 Notes were
issued at a premium resulting in an effective rate of 8.5%. The terms of the
1995 Notes and the 1999 Notes are substantially the same, and the 1995 Notes and
the 1999 Notes were issued pursuant to indentures that are substantially the
same. The issuance of the 1999 Notes improved the Company's financial liquidity
by i) using a portion of the proceeds to repay $30 million of debt associated
with the Rockwell acquisition that bore interest at 9.56%; ii) using a portion
of the proceeds to repay variable-rate revolving credit borrowings thereby
increasing amounts available under the revolving credit facility; and iii)
repaying the remaining unpaid principal of $10.2 million from the Comet
acquisition. As result of this issuance, the Company wrote off previously
capitalized debt issuance costs of $469,000, net of tax, or approximately $.01
per diluted share, in the first quarter of 1999.

The Notes are senior unsecured obligations of the Company and rank pari passu in
right of payment with all existing and future indebtedness under (i) capitalized
lease obligations, (ii) the Credit Agreement, (iii) indebtedness of the Company
for money borrowed and (iv) indebtedness evidenced by notes, debentures, bonds
or other similar instruments for the payment of which the Company is responsible
or liable unless, in the case of clause (iii) or (iv), in the instrument
creating or evidencing the same or pursuant to which the same is outstanding, it
is provided that such obligations are subordinate in right of payment to the
Notes.

Unsecured Credit Facility

In October 1998, the Company obtained a $30 million unsecured credit facility
from a group of commercial banks for the purpose of financing the Rockwell
acquisition. In January 1999, this facility was repaid with proceeds of the 1999
Notes offering.

Pulse Note

As partial payment for the Pulse acquisition, the Company issued a $17 million
note due January 31, 2004, with interest at 9.5%. In January 2000, this note was
repaid with our revolving credit facility.

Comet Notes

In connection with the Comet acquisition, the Company issued notes totaling
$12.2 million, of which unsecured notes totaling $6.2 million were delivered by
the Company and a note in the amount of $6 million was delivered by a subsidiary
of the Company and secured by the acquired assets. These notes were repaid in
January 1999 with proceeds of the 1999 Notes offering.

Industrial Revenue Bond

In July 1998, a subsidiary of the Company entered into a 10 year $7.5 million
debt obligation that bears an interest rate of 5.5% to provide financing for the
purchase of a building used in the Company's operations.

Scheduled principal repayments of outstanding loan balances required as of
December 31, 1999 are as follows:

</TABLE>

The Company sponsors defined benefit pension plans that cover certain U.S. and
Canadian employees and provide benefits of stated amounts for each year of
service of the employee. In connection with the establishment of the ESOP (see
Note 8) in January 1995, the pension plan for U.S. salaried employees was
modified to eliminate any credit (or accrual) for current service costs for any
future periods, effective March 31, 1995.

In connection with the acquisition of Young Radiator Company in November 1998,
the Company assumed liability for Young's defined benefit pension plan (the
"Young Plan"), covering substantially all of the employees of Young. The
benefits under the Young Plan are based on years of service. The Company
suspended future benefits accruing under this plan as of April 1, 1999, and is
proceeding with merging the Young Plan into an existing Company defined benefit
plan.

The Company's funding methods, which are primarily based on the ERISA
requirements, differ from those used to recognize pension expense, which is
primarily based on the projected unit credit method applied in the accompanying
financial statements.

In addition to providing pension benefits, the Company has provided certain
unfunded postretirement health care and life insurance benefits for
substantially all U.S. employees. In conjunction with the establishment of the
ESOP in January 1995 (see Note 8), the postretirement health care and life
insurance benefits for salaried employees were modified to discontinue benefits
for employees who had not attained the age of 50 by March 31, 1995. The Company
is not obligated to pay health care and life insurance benefits to individuals
who had retired prior to 1990.

The Company also participates in a variety of defined contribution 401(k), ESOP
and multiemployer pension, health and welfare plans. With regard to the 401(k)
savings and the ESOP, during 1999 the Company match was substantially in the
form of Wabtec Common Stock and cash. Additionally, the Company has stock option
based and other plans further described in Note 11.

8. EMPLOYEE STOCK OWNERSHIP PLAN AND TRUST (ESOP)

Effective January 31, 1995, the Company established the ESOP to enable
participating employees to obtain ownership interests in the Company. Employees
eligible to participate in the ESOP primarily include the salaried U.S.
employees and, as described in Note 7, the ESOP contributions are intended to
supplement or replace other salaried employee benefit plans.

In connection with the establishment of the ESOP, the Company made a $140
million loan to the ESOP, which was used to purchase 9,336,000 shares of the
Company's outstanding common stock. The ESOP loan initially had a term of 50
years with interest at 8.5% and was collateralized by the shares purchased by
the ESOP. Company contributions to the ESOP will be used to repay the ESOP
loan's annual debt service requirements of approximately $12 million. The
Company is obligated to contribute amounts sufficient to repay the ESOP loan.
The ESOP uses such Company contributions to repay the ESOP loan. Approximately
187,000 shares were to be allocated annually to participants over a 50-year
period. These transactions occur simultaneously and, for accounting purposes,
offset each other. Unearned ESOP shares of $125.5 million at December 31, 1999,
is reflected as a reduction in shareholders' equity in the accompanying
financial statements and will be amortized to compensation expense coterminous
with the ESOP loan. Allocated ESOP shares at December 31, 1999 and 1998 were
approximately 970,000 and 771,000 shares, respectively.

The 1999 and 1998 provision excludes $0.8 and $2.0 million income tax effect on
the extraordinary loss (See Note 6).

The components of income before taxes for U.S. and foreign operations were $38.7
million and $32.8 million, respectively, for 1999, $81.2 million and $40.1
million, respectively, for 1998, and $69.0 million and $23.6 million,
respectively, for 1997.

A valuation allowance is provided when it is more likely than not that some
portion or all of the deferred tax assets will not be realized. The Company has
established a valuation allowance for certain net operating loss carryforwards
and for losses anticipated to produce no tax benefit. Although realization of
the net deferred tax asset is not assured, management believes that it is more
likely than not that the net deferred tax asset will be realized.

The Company's net operating loss carryforward for the year ended December 31,
1999 is $24 million. The net operating losses expire in various amounts, as
follows:

</TABLE>

Options to purchase approximately 700,000, 200,000 and 500,000 shares of Common
Stock were outstanding in 1999, 1998, and 1997, respectively, but were not
included in the computation of diluted earnings per share because the options'
exercise price exceeded the average market price of the common shares.

11. STOCK-BASED COMPENSATION PLANS

STOCK OPTIONS Under the 1995 Stock Incentive Plan, as amended in 1998, the
Company may grant options to employees of the former Westinghouse Air Brake
Company and MotivePower Industries, Inc. and Subsidiaries for up to 6.5 million
shares of Common Stock. Options to purchase approximately 5.8 million shares of
Common Stock under the plans have been granted to employees at, or in excess of,
fair market value at the date of grant. Generally, the options become
exercisable over three and five-year vesting periods and expire ten years from
the date of grant.

As part of a long-term incentive program, in 1998 and 1996 the Company granted
options to purchase up to 500,020 and 684,206 shares, respectively, to certain
executives under the 1995 Stock Incentive Plan. The option price per share is
the greater of the market value of the stock on the date of grant or $20 and
$14, respectively. The options vest 100% after eight years and are subject to
accelerated vesting after three years if the Company achieves certain earnings
targets as established by the compensation committee of the board of directors.

The Company also has a non-employee directors stock option plan under which
100,000 shares of common stock are reserved for issuance. Through year-end 1999,
the Company granted nonstatutory stock options to non-employee directors to
purchase a total of 40,000 shares.

EMPLOYEE STOCK PURCHASE PLAN In 1998, the Company adopted an employee stock
purchase plan (ESPP). The ESPP had 500,000 shares available for issuance.
Participants purchased the Company's Common Stock at 85% of the lesser of fair
market value on the first or last day of each offering period. This plan was
suspended during 1999 and will be reinstated starting April 2000.

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

</TABLE>

Since compensation expense associated with option grants would be recognized
over the vesting period, the initial impact of applying SFAS No. 123 on pro
forma net income is not representative of the potential impact on pro forma net
income in future years.
                                       42
<PAGE>   44

In each subsequent year, pro forma compensation expense would include the effect
of recognizing a portion of compensation expense from multiple awards.

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

</TABLE>

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

RESTRICTED STOCK AWARD In 1998, the Company granted 15,000 shares of restricted
Common Stock to an officer. The shares vest according to a vesting schedule over
a three-year period. The grant date market value totaled $372,000 and is being
amortized to expense over the vesting period. Unamortized compensation is
recorded as a component of shareholders' equity.

EXECUTIVE RETIREMENT PLAN Under the 1997 Executive Retirement Plan, the Company
may award its

                                       43
<PAGE>   45

Common Stock to certain employees including certain executives who do not
participate in the ESOP. Through December 31, 1999, 35,556 shares have been
awarded with a fair market value of approximately $704,000.

With respect to the Restricted Stock Award and the Executive Retirement Plan,
compensation expense is recognized in the consolidated statement of operations.

12. OPERATING LEASES

The Company leases office and manufacturing facilities under operating leases
with terms ranging from one to fifteen years, excluding renewal options.

The Company has sold remanufactured locomotives to various financial
institutions and leased them back under operating leases with terms from five to
20 years.

Total net rental expense charged to operations in 1999, 1998 and 1997 was $8.6
million, $6.2 million and $6.1 million, respectively. Certain of the Company's
equipment rental obligations under operating leases pertain to locomotives,
which are subleased to customers under both short-term and long-term agreements.
The amounts above are shown net of sublease rentals of $5.7 million, $7.6
million and $7.2 million for the years 1999, 1998 and 1997, respectively.

Future minimum rental payments under operating leases with remaining
noncancelable terms in excess of one year are as follows:

13. STOCKHOLDERS' AND VOTING TRUST
    AGREEMENTS

As of December 31, 1999, the approximate ownership interests in the Company's
Common Stock are held by management (14%), the ESOP (22%), the investors
consisting of Vestar Equity Partners, L.P., Harvard Private Capital Holdings,
Inc., American Industrial Partners Capital Fund II, L.P. (13%), and all others
including public shareholders (51%).

A Stockholders Agreement exists between management and the investors referred to
above that provides for, among other things, the composition of the Board of
Directors as long as certain minimum stock ownership percentages are maintained,
restrictions on the disposition of shares and rights to request the registration
of the shares.

The active original management owners have entered into an Amended Voting
Trust/Disposition Agreement effective December 13, 1995, as amended. The
agreement provided for, among other matters, the stock to be voted as one block
and restrictions on the sale or transfer of such stock. The agreement expired on
January 1, 2000. Individual stockholders now vote their own shares.

The shares held by the ESOP (established January 31, 1995) are subject to the
terms of the related ESOP Loan Agreement, Employee Stock Ownership Trust
Agreement, Employee Stock Ownership Plan and the Pledge Agreement. The ESOP is
further described in Note 8.

14. PREFERRED STOCK

The Company's authorized capital stock includes 1,000,000 shares of preferred
stock. The Board of Directors has the authority to issue the preferred stock and
to fix the designations, powers, preferences and rights of the shares of each
such class or series, including dividend rates, conversion rights, voting
rights, terms of redemption and liquidation preferences, without any further
vote or action by the Company's shareholders. The rights and preferences of the
preferred stock would be superior to those of the common stock. At December 31,
1999 and 1998 there was no preferred stock issued or outstanding.

15. COMMITMENTS AND CONTINGENCIES

The Company is subject to a variety of environmental laws and regulations
governing discharges to air and water, the handling, storage and disposal of
hazardous or solid waste materials and the remediation of contamination
associated with releases of hazardous substances. The Company believes its
operations currently comply in all material respects with all of the various
environmental laws and regulations applicable to our business; however, there
can be no assurance that environmental requirements will not change

                                       44
<PAGE>   46

in the future or that we will not incur significant costs to comply with such
requirements.

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

The Company, through one of its operating subsidiaries, has been named, along
with other parties, as a Potentially Responsible Party (PRP) under the North
Carolina Inactive Sites Response Act because of an alleged release or threat of
release of hazardous substances at the "Old James Landfill" site in North
Carolina. The Company believes that any costs associated with the cleanup
activities at this site which it may be held responsible for, if any, are
covered by (a) the ASI indemnification referred to above, as ASI previously
owned 50% of the subsidiary and (b) a related insurance policy which expires
January 2002 for environmental claims provided by the other former 50% owner of
the involved operating subsidiary. Active claims for conditions existing prior
to July 1992 will continue to be covered beyond such date. The Company has
submitted a claim and has received recoveries under the policy for any costs of
clean up imposed on or incurred by the Company in connection with the "Old James
Landfill" and Rocky Mountain International Insurance, Ltd. has acknowledged
coverage and has made payments under the policy, subject to the stated policy
exclusions. Claims made before the expiration date of the policy will continue
to be covered beyond the policy expiration date. In addition, management
believes that such costs, if any, attributable to the Company will not be
material and, therefore, has not established a reserve for such costs.

The Company's operations do not use and its products do not contain any
asbestos. Asbestos actions have been filed against the Company, RFPC and Vapor
Corporation. These cases involve products manufactured prior to the time the
Company acquired the RFPC stocks and Vapor assets and while the Company was
under prior ownership. With respect to the actions filed against the Company,
ASI is responsible for administering, defending and paying any liability
associated with the claims. With respect to the actions filed against RFPC, the
claims are covered by insurance. With respect to the actions filed against Vapor
Corporation, the Company seeks indemnity for liability and defense costs from
the prior owner of the Vapor assets. The Company is not involved with, nor has
it incurred any costs related to, these asbestos claims, other than minimal
processing costs. Management believes that these claims are not related to the
Company and will not be material; the financial statements accordingly do not
reflect any costs or reserves for such claims.

BOISE, IDAHO

The Company is subject to a RCRA Part B Closure Permit ("the Permit") issued by
the Environmental Protection Agency (EPA) and the Idaho Department of Health and
Welfare, Division of Environmental Quality relating to the monitoring and
treatment of groundwater contamination on, and adjacent to, the Boise Locomotive
Company facility. In compliance with the Permit, the Company has drilled wells
onsite to retrieve and treat contaminated groundwater, and onsite and offsite to
monitor the amount of hazardous constituents. The Company has estimated the
expected aggregate discounted liability at December 31, 1999, using a discount
rate of 6%, to be approximately $4 million, which has been accrued. The Company
was in compliance with the Permit at December 31, 1999.

MOUNTAINTOP, PENNSYLVANIA

Foster Wheeler Energy Corporation ("FWEC") is named as a potentially responsible
party with respect to the Company's Mountaintop, Pennsylvania plant, which has
been listed by the EPA in its database of potential hazardous substances. FWEC,
the seller of the Mountaintop property to the Company's predecessor in 1989,
agreed to indemnify the Company's predecessor against certain identified
liabilities for which FWEC executed a Consent Order Agreement with the
Pennsylvania Department of Environmental Protection (PADEP) and EPA. Management
believes that this indemnification arrangement is enforceable for the benefit of
the Company and that FWEC has the financial resources to honor its obligations
under this indemnification arrangement.

                                       45
<PAGE>   47

MATTOON, ILLINOIS

Prior to the acquisition of Young Radiator, Young agreed to clean up alleged
contamination on a prior production site in Mattoon, IL. The Company has accrued
$1 million for this matter as management's best estimate of the restoration
costs.

RACINE, WISCONSIN

Young ceased manufacturing operations at its Racine facility in the early
1990's. Investigations prior to the acquisition of Young revealed some levels of
contamination on the Racine property. The Company is in the process of
determining the extent of contamination.

GE HARRIS

On February 12, 1999, GE Harris Railway Electronics, LLC and GE Harris Railway
Electronic Services, LLC (collectively, "GE Harris") brought suit against the
Company for alleged patent infringement and unfair competition related to a
communications system installed in one of the Company's products. GE Harris is
seeking to prohibit the Company from future infringement and is seeking an
unspecified amount of money damages to recover, in part, royalties. As this
lawsuit is in the early stages, the Company is unable to estimate the cost, if
any, of resolving litigation and thus, no costs have been provided for this
matter.

From time to time the Company is involved in litigation relating to claims
arising out of its operations in the ordinary course of business. As of the date
hereof, the Company is involved in no litigation that the Company believes will
have a material adverse effect on its financial condition, results of operations
or liquidity.

16. SEGMENT INFORMATION

Wabtec has two reportable segments -- the Freight Group and the Transit Group.
The key factors used to identify these reportable segments are the organization
and alignment of the Company's internal operations, the nature of the products
and services and customer type. Financial information for these segments has
been restated in conjunction with the operational realignment of our
organization pursuant to the merger of WABCO and MotivePower. The business
segments are:

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

TRANSIT GROUP consists of products for passenger transit vehicles (typically
subways, rail and busses) that include braking and monitoring systems, climate
control and door equipment that are engineered to meet individual customer
specifications. Revenues are derived from OEM and aftermarket sales as well as
from repairs and services.

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

</TABLE>

The amounts in the table above differ from those previously reported on Form
10-Q due to the merger of Westinghouse Air Brake Company and MotivePower
Industries, Inc. and the application of the pooling-of-interests accounting and
reporting method.

In the fourth quarter of 1999, the Company recorded merger and restructuring
costs of approximately $50 million or $0.92, net of tax, per diluted share.
Without the effect of this charge, the fourth quarter 1999 would have been $0.39
per diluted share. In the fourth quarter of 1998, the Company sold its entire
Argentine investment in Trenes de Buenos Aires S.A. and recognized a
non-recurring investment gain of $8.4 million or $0.12 net of tax, per diluted
share. Without the effect of this gain, the fourth quarter 1998 would have been
$0.35 per diluted share.

19. MERGER AND RESTRUCTURING
    CHARGES

The Company incurred merger and restructuring-related charges of approximately
$50 million in the fourth quarter of 1999 and expects to incur an additional $20
million of merger and restructuring-related expenses in 2000. The $50.1 million
charge is included in the income statement under the following items: $43.6
million of the charge is included as a separate line item on the income
statement as an operating expense; $5.2 million is included as a component of
cost of sales; and $1.3 million ($850,000, net of tax) is shown as an
extraordinary item.

The $50 million charge included the following announced actions:

 --  Costs associated with the transaction for items such as investment bankers,
     legal fees, accountant fees, SEC fees, etc.

 --  Consolidation of the corporate headquarters to Wilmerding, PA and the
     elimination of duplicate corporate functions.

 --  Closing and moving of Young Radiators' Centerville, IA plant and downsizing
     the Young administrative offices into the Company's Jackson, TN facility.

 --  Closing of G&G Locotronic's plant in Itasca, IL and moving its production
     into the nearby Elk Grove, IL facility and to San Luis Potosi, Mexico.

 --  Implementing a national sales force and eliminating duplicate sales
     functions.

183 employees, comprising both salaried and hourly personnel, at the various
locations noted above. The accrual represents the calculation of the severance
package based on the employee's salary and tenure with the Company. The lease
impairment charges and asset write downs are associated with the Company's
closing of the plants noted, the relocation of the corporate headquarters, and
the Company's evaluation of certain assets. The other category represents other
related costs that have been incurred and not yet paid as of December 31, 1999.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORPORATION:

We have audited, in accordance with auditing standards generally accepted in the
United States, the consolidated financial statements of Westinghouse Air Brake
Technologies Corporation included in this Form 10-K, and have issued our report
thereon dated February 15, 2000. Our audit was made for the purpose of forming
an opinion on the basic financial statements taken as a whole. The schedule
listed in the index in Item 14(a)2 of this Form 10-K is the responsibility of
the Company's management and is presented for purposes of complying with the
Securities and Exchange Commission's rules and is not part of the basic
financial statements. This schedule has been subjected to the auditing
procedures applied in the audit of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data required to
be set forth therein in relation to the basic financial statements taken as a
whole.

Agreement): (a) references to the plural include the singular, the plural, the
part and the whole; unless the context clearly indicates otherwise "or" has the
inclusive meaning represented by the phrase "and/or," and "including" has the
meaning represented by the phrase "including without limitation"; (b) references
to "determination" of or by the Agent or the Banks shall be deemed to include
good-faith estimates by the Agent or the Banks (in the case of quantitative
determinations) and good-faith beliefs by the Agent or the Banks (in the case of
qualitative determinations) and such determination shall be conclusive absent
manifest error; (c) whenever the Agent or the Banks are granted the right herein
to act in its or their sole discretion or to grant or withhold consent such
right shall be exercised in good faith; (d) the words "hereof," "herein,"
"hereunder," "hereto," and similar terms in this Agreement or any other Loan
Document refer to this Agreement or such other Loan Document as a whole and not
to any particular provision of this Agreement or such other Loan Document; (e)
the section and other headings contained in this Agreement or such other Loan
Document and the Table of Contents (if any) preceding this Agreement or such
other Loan Document are for reference purposes only and shall not control or
affect the construction of this Agreement or such other Loan Document or the
interpretation thereof in any respect; (f) article, section, subsection, clause,
schedule, and exhibit references are to this Agreement or other Loan Document,
as the case may be, unless otherwise specified; (g) reference to any Person
includes such Person's successors and assigns but, if applicable, only if such
successors and assigns are permitted by this Agreement or such other Loan
Document, as the case may be, and reference to a Person in a particular capacity
excludes such Person in any other capacity; (h) reference to any agreement
(including this Agreement and any other Loan Document together with the
schedules and exhibits hereto or thereto), document, or instrument means such
agreement, document or instrument as amended, modified, replaced, substituted
for, superseded, or restated; (i) relative to the determination of any period of
time, "from" means "from and including," "to" means "to but excluding," and
"through" means "through and including"; and; references to "shall" and "will"
are intended to have the same meaning.

Accounting Principles.

         Except as otherwise provided in this Agreement, all computations and
determinations as to accounting or financial matters and all financial
statements to be delivered pursuant to this Agreement shall be made and prepared
in accordance with GAAP (including principles of consolidation where
appropriate), and all accounting or financial terms shall have the meanings
ascribed to such terms by GAAP; provided, however, that all accounting terms
used in Section 8.2 [Negative Covenants] and all defined terms used in the
definition of any accounting term used in Section 8.2 shall have the meaning
given to such terms (and defined terms) under GAAP as in effect on the date
hereof, applied on a basis consistent with those used in preparing the Annual
Statements referred to in Section 6.1.8(i). In the event of any change after the
date hereof in GAAP or in the fiscal year of Borrower or any Subsidiary thereof,
and if such change would result in the inability to determine compliance with
the financial covenants set forth in Section 8.2 based upon the Borrower's
regularly prepared financial statements by reason of the preceding sentence,
then the parties hereto agree to endeavor, in good faith, to agree upon an
amendment to this Agreement that would adjust such financial covenants in a
manner that would not affect the substance thereof, but would allow compliance
therewith to be determined in accordance with the Borrower's financial
statements at that time.

REVOLVING CREDIT FACILITY

Revolving Credit Commitments.

         Subject to the terms and conditions hereof and relying upon the
representations and warranties herein set forth, each Bank severally agrees to
make Revolving Credit Loans to the Borrower at any time or from time to time on
or after the date hereof to the Revolving Credit Expiration Date, provided that
after giving effect to each such Loan the aggregate amount of Revolving Credit
Loans from such Bank shall not exceed such Bank's Revolving Credit Commitment
minus such Bank's Ratable Share of the Letters of Credit Outstanding and Ratable
Share of Swingline Loans. Within such limits of time and amount and subject to
the other provisions of this Agreement, the Borrower may borrow, repay, and
reborrow pursuant to this Section 2.1. All outstanding Revolving Credit Loans
shall be due and payable on the Revolving Credit Expiration Date.

Nature of Banks' Obligations With Respect to Revolving Credit Loans.

         Each Bank shall be obligated to participate in each request for
Revolving Credit Loans pursuant to Section 2.5 in accordance with its Ratable
Share. The aggregate of each Bank's Revolving Credit Loans outstanding hereunder
to the Borrower at any time shall never exceed its Revolving Credit Commitment
minus its Ratable Share of the Letters of Credit Outstanding and Ratable Share
of Swingline Loans. The obligations of each Bank hereunder are several and not
joint. The failure of any Bank to perform its obligations hereunder shall not
affect the Obligations of the Borrower to any other party nor shall any other
party be liable for the failure of such Bank to perform its obligations
hereunder. The Banks shall have no obligation to make Revolving Credit Loans
hereunder on or after the Revolving Credit Expiration Date.

Commitment Fees.

         The Borrower agrees to pay to the Agent for the account of each Bank,
as consideration for such Bank's Revolving Credit Commitment and Convertible
Revolving Credit Commitment hereunder, a nonrefundable commitment fee (the
"Commitment Fee") accruing from the date hereof until the Revolving Credit
Expiration Date and equal to the Applicable Revolving Credit Commitment Fee Rate
and the Applicable Convertible Revolving Credit Commitment Fee Rate (computed on
the basis of a year of 360 days for the actual number of days elapsed) on the
respective average daily unused amount of (i) such Bank's Revolving Credit
Commitment, and (ii) such Bank's Convertible Revolving Credit Commitment. All
Commitment Fees shall be payable quarterly in arrears on the first Business Day
of each January, April, July, and October after the date hereof and on, as
applicable, (A) the Revolving Credit Expiration Date, and (B) the Convertible
Revolving Credit Expiration Date, or in any event upon acceleration of the
Loans. For purposes of calculating Commitment Fees only, no portion of the
Revolving Credit Commitments shall be deemed utilized under Section 5.2 as a
result of outstanding Bid Loans or Swingline Loans. For the purpose of
calculating Commitment Fees in respect of Revolving Credit Commitments, any
portion of the Revolving Credit Commitments unavailable due to outstanding
Letters of Credit shall be deemed to be used amounts.

Additional Fees.

         The Borrower agrees to pay to the Agent for its own account the fees
and costs set forth in the Agent's Letter. All fees payable hereunder shall be
nonrefundable and deemed earned in full when due.

Base Rate Option for any such Loan, a duly completed Committed Loan Request
therefor substantially in the form of Exhibit 2.5 or a Committed Loan Request by
telephone immediately confirmed in writing by letter, facsimile, or telex in the

necessity of receipt of such written confirmation. Each Loan Request shall be
irrevocable and shall specify (i) the proposed Borrowing Date; (ii) the
aggregate amount of the proposed Revolving Credit Loans comprising each
Borrowing Tranche, which shall be in integral multiples of $1,000,000 and not
less than $2,500,000 for each Borrowing Tranche to which the Euro-Rate Option
applies and in integral multiples of $500,000 and not less than the lesser of
$1,000,000 or the maximum amount available for Borrowing Tranches to which the
Base Rate Option applies; (iii) whether Committed Loan Euro-Rate Option or Base

and type of each such Revolving Credit Loan and the applicable Interest Period
(if any); and (iii) the apportionment among the Banks of such Revolving Credit
Loans as determined by the Agent in accordance with Section 2.2. Each Bank shall
remit the principal amount of each Revolving Credit Loan to the Agent such that
the Agent is able to, and the Agent shall, to the extent the Banks have made
funds available to it for such purpose and subject to Section 7.2, fund such
Revolving Credit Loans to the Borrower in U.S. Dollars and in immediately
available funds at the Principal Office in New York City prior to 2:00 p.m., New
York time, on the applicable Borrowing Date, provided that if any Bank fails to
remit such funds to the Agent in a timely manner, the Agent may elect in its
sole discretion to fund with its own funds the Revolving Credit Loans of such
Bank on such Borrowing Date, and such Bank shall be subject to the repayment
obligation in Section 10.16.

Use of Proceeds.

         The proceeds of the Revolving Credit Loans, Convertible Revolving
Credit Loans, Swingline Loans, and Bid Loans and the Letters of Credit shall be

Bid Loan Requests.

                  Except as otherwise provided herein, the Borrower may from
time to time prior to the Revolving Credit Expiration Date request that the
Banks make Bid Loans by delivery to the Agent at its Principal Office in New
York not later than 12:00 noon, New York time, of a duly completed request
therefor substantially in the form of Exhibit 2.8.1 hereto or a request by
telephone immediately confirmed in writing by letter, facsimile, or telex (each,
a "Bid Loan Request") at least two (2) Business Days prior to the proposed Bid
Loan Borrowing Date if Borrower is requesting Fixed Rate Bid Loans and four (4)
Business Days prior to the proposed Bid Loan Borrowing Date if Borrower is
requesting Euro-Rate Bid Loans. The Agent may rely on the authority of any
individual making a telephonic request referred to in the preceding sentence
without the necessity of receipt of written confirmation. Each Bid Loan Request
shall be irrevocable and shall specify (i) the proposed Bid Loan Borrowing Date,
(ii) whether Borrower is electing the Bid Loan Fixed Rate Option or the Bid Loan
Euro-Rate Option, (iii) the term of the proposed Bid Loan (the "Bid Loan
Interest Period") which may be no less than thirty (30) days and no longer than
one hundred eighty (180) days, if Borrower is requesting a Fixed Rate Bid Loan,
or one, two, three, or six Months, if Borrower is requesting a Euro-Rate Bid
Loan, and (iv) the maximum principal amount (the "Requested Amount") of such Bid
Loan, which shall be not less than $5,000,000 and shall be an integral multiple
of $1,000,000. After giving effect to such Bid Loan and any other Loan made on
or before the Bid Loan Borrowing Date, (i) the aggregate amount of the Bid Loans
of all Banks outstanding shall not exceed $100,000,000 (the "Bid Loan Aggregate
Sublimit"), (ii) the aggregate amount of all Revolving Credit Loans, Swingline
Loans, and Bid Loans outstanding plus the Letters of Credit Outstanding shall
not exceed the aggregate amount of the Revolving Credit Commitments then
existing of the Banks, and (iii) the aggregate amount of all Revolving Credit
Loans, Convertible Revolving Credit Loans, Swingline Loans and Bid Loans
outstanding plus the Letters of Credit Outstanding shall not exceed the
aggregate amount of the Revolving Credit Commitments and Convertible Revolving

(15) Business Days between each Bid Loan Borrowing Date.

Bidding.

                  The Agent shall promptly after receipt by it of a Bid Loan
Request pursuant to Section 2.8.1 notify the Banks of its receipt of such Bid
Loan Request specifying (i) the proposed Bid Loan Borrowing Date, (ii) whether
the proposed Bid Loan shall be a Fixed Rate Bid Loan or a Euro-Rate Bid Loan,
(iii) the Bid Loan Interest Period, and (iv) the principal amount of the
proposed Bid Loan. Each Bank may in its sole discretion submit a bid (a "Bid")
to the Agent at its Principal Office in New York not later than 10:00 a.m., New
York time, one (1) Business Day before the proposed Bid Loan Borrowing Date if
Borrower is requesting a Fixed Rate Bid Loan, or three (3) Business Days before
the proposed Bid Loan Borrowing Date if Borrower is requesting a Euro-Rate Bid
Loan by telephone (immediately confirmed in writing by letter, facsimile or
telex). Each Bid shall specify: (A) the principal amount of proposed Bid Loans
offered by such Bank (the "Offered Amount") which (i) may be less than, but
shall not exceed, the Requested Amount, (ii) shall be at least $1,000,000 and
shall be an integral multiple of $1,000,000 and (iii) may exceed such Bank's
Revolving Credit Commitment, and (B) the Fixed Rate which shall apply to such
proposed Bid Loan, if Borrower has requested a Fixed Rate Bid Loan, or the
Euro-Rate Bid Loan Spread which shall apply to such proposed Bid Loan if
Borrower has requested a Euro-Rate Bid Loan. If any Bid omits information
required hereunder, the Agent may in its sole discretion attempt to notify the
Bank submitting such Bid. If the Agent so notifies a Bank, such Bank may
resubmit its Bid, provided that it does so prior to the time set forth in this
Section 2.8.2 above by which such Bank is required to submit its Bid to the
Agent. The Agent shall promptly notify the Borrower of the Bids which it
received from the Banks on a timely basis. If the Agent in its capacity as a


                                      -24-
<PAGE>   37


Bank shall, in its sole discretion, make a Bid, it shall notify the Borrower of
such Bid before 9:00 a.m., New York time, one (1) Business Day before the
proposed Bid Loan Borrowing Date, if Borrower is requesting a Fixed Rate Bid
Loan, or three (3) Business Days before the proposed Borrowing Date if Borrower
is requesting a Euro-Rate Bid Loan.

Accepting Bids.

                  The Borrower shall irrevocably accept or reject Bids by
notifying the Agent at its Principal Office in New York of such acceptance or
rejection by telephone (immediately confirmed in writing by letter, facsimile,
or telex) not later than 11:00 a.m., New York time, one (1) Business Day before
the proposed Bid Loan Borrowing Date, if Borrower is requesting a Fixed Rate Bid
Loan, or three (3) Business Days before the proposed Borrowing Date if Borrower
is requesting a Euro-Rate Bid Loan. If the Borrower elects to accept any Bids,
its acceptance must meet the following conditions: (1) it shall be irrevocable
and the total amount which Borrower accepts from all Banks must not be less than
$5,000,000 and be in integral multiples of $1,000,000 and may not exceed the
Requested Amount; (2) the Borrower must accept Bids based solely on the amount
of the Fixed Rates or Euro-Rate Bid Loan Spreads, as the case may be, which each
of the Banks quoted in their Bids in ascending order of the amount of Fixed
Rates or Euro-Rate Bid Loan Spreads; (3) the Borrower may not borrow Bid Loans
from any Bank on the Bid Loan Borrowing Date in an amount exceeding such Bank's
Offered Amount; (4) if two or more Banks make Bids at the same Fixed Rate (if
Borrower Requested a Fixed Rate Bid Loan) or Euro-Rate Bid Loan Spread (if
Borrower Requested a Euro-Rate Bid Loan) and the Borrower desires to accept a
portion but not all of the Bids at such Fixed Rate or Euro-Rate Bid Loan Spread,
as the case may be, the Borrower shall accept a portion of each Bid equal to the
product of the Offered Amount of such Bid times the fraction obtained by
dividing the total amount of Bids which Borrower is accepting at such Fixed Rate
or Euro-Rate Bid Loan Spread, as the case may be, by the sum of the Offered
Amounts of the Bids at such Fixed Rate or Euro-Rate Bid Loan Spread, provided
that the Borrower shall round the Bid Loans allocated to each such Bank upward
or downward as the Borrower may select to integral multiples of $1,000,000. The
Agent shall (i) promptly notify a Bank that has made a Bid of the amount of its
Bid that was accepted or rejected by the Borrower and (ii) as promptly as
practical notify all of the Banks of all Bids submitted and those which have
been accepted.

Funding Bid Loans.

                  Each Bank whose Bid or portion thereof is accepted shall remit
the principal amount of its Bid Loan to the Agent at its Principal Office in New
York by 12:00 noon on the Borrowing Date. The Agent shall make such funds
available to the Borrower on or before 1:00 p.m. on the Borrowing Date, provided
that the conditions precedent to the making of such Bid Loan set forth in
Section 7.2 have been satisfied not later than 10:00 a.m., New York time, on the
proposed Borrowing Date. If such conditions precedent have not been satisfied
prior to such time, then (i) the Agent shall not make such funds available to
the Borrower, (ii) the Bid Loan Request shall be deemed to be revoked by
Borrower, and (iii) the Agent shall return the amount previously funded to the
Agent by each applicable Bank no later than the directly following Business Day.
The Borrower shall immediately notify the Agent of any failure to satisfy the
conditions precedent to the making of Bid Loans under Section 7.2. The Agent may
assume that Borrower has satisfied such conditions precedent if the Borrower (i)
has delivered to the Agent at its Principal Office in New York the documents
required to be delivered under Section 7.2, (ii) the Borrower has not notified
the Agent at its Principal Office in New York that the Loan Parties have not
satisfied any other conditions precedent, and (iii) the Agent has no actual
notice of such a failure.

Several Obligations.

                  The obligations of the Banks to make Bid Loans after their
Bids have been accepted are several and not joint. No Bank shall be responsible
for the failure of any other Bank to make any Bid Loan which another Bank has
agreed to make.

Bid Notes.

                  The obligation of the Borrower to repay the aggregate unpaid
principal amount of the Bid Loans made to it by each Bank, together with
interest thereon, shall be evidenced by a Bid Note dated as of the date hereof
payable to the order of such Bank in a face amount equal to the aggregate
Revolving Credit Commitments of all of the Banks. Each Bid Loan shall be due and
payable on the last day of its respective Bid Loan Interest Period.

Letter of Credit Subfacility.

Issuance of Letters of Credit.

                  Subject to the terms and conditions and relying on the
representations and warranties herein set forth, Chase Manhattan Bank Delaware
agrees to continue outstanding until expiration each of the Letters of Credit
issued by it and listed on Schedule 2.9.1(A) and to be an Issuing Bank solely
with respect to such Letters of Credit. Subject to the terms and conditions and
relying on the representations and warranties herein set forth, ABN AMRO Bank
N.V. agrees to continue outstanding until expiration each of the Letters of
Credit issued by it and listed on Schedule 2.9.1(B).

                  Borrower may request the issuance of a letter of credit (each
a "Letter of Credit") on behalf of itself or on behalf of any other Loan Party
(provided that Borrower is the account party thereon) by delivering to the Agent
at its Principal Office in New York and to the Issuing Bank a completed
application and agreement for letters of credit in such form as the Issuing Bank
may specify from time to time by no later than 10:00 a.m., New York time, at
least three (3) Business Days, or such shorter period as may be agreed to by the
Issuing Bank, in advance of the proposed date of issuance. Each Letter of Credit
shall be either a Standby Letter of Credit or a Commercial Letter of Credit and
shall be denominated in Dollars or if a different currency is requested by the
Borrower, a currency satisfactory to the Issuing Bank. Subject to the terms and
conditions hereof and in reliance on the agreements of the other Banks set forth
in this Section 2.9, the Issuing Bank will issue a Letter of Credit provided
that each Letter of Credit shall expire no later than twenty (20) Business Days
prior to the Revolving Credit Expiration Date and provided that in no event
shall (i) the Letters of Credit Outstanding exceed, at any one time, $85,000,000
or (ii) the Revolving Facility Usage exceed, at any one time, the Revolving
Credit Commitments

                  If on any date the aggregate Letter of Credit Outstandings, in
the equivalent amount of US Dollars at exchange rates then prevailing and
available to the Agent, exceed $85,000,000 (such excess amount, calculated at
any time and from time to time, being referred to herein as the "Exchange Rate
L/C Excess Amount"), the Borrower shall thereupon deposit in a interest-bearing
account with the Agent (the "L/C Cash Collateral Account"), as cash collateral
for its Letter of Credit Obligations under the Loan Documents, an amount equal
to the Exchange Rate L/C Excess Amount, and the Borrower hereby pledges to the
Agent for the benefit



                                      -26-
<PAGE>   39


of each Issuing Bank, and grants to the Agent for the benefit of each Issuing
Bank a security interest in, all such cash, deposit, and account, and the
proceeds thereof, as security for such Letter of Credit Obligations.

Letter of Credit Fees.

                  The Borrower shall pay (i) to the Agent at its Principal
Office in New York for the ratable account of the Banks (a) with respect to
Commercial Letters of Credit, a nonrefundable fee (the "Commercial Letter of
Credit Fee") equal to the basis points per annum at the indicated level of the
ratio of Consolidated Total Indebtedness to Cash Flow in the Revolving Credit
Pricing Grid on Schedule 1.1(A) below the heading "Commercial Letter of Credit
Fee" which Commercial Letter of Credit Fee shall be computed in accordance with
the parameters set forth on Schedule 1.1(A), and (b) with respect to Standby
Letters of Credit, a nonrefundable fee (the "Standby Letter of Credit Fee")
equal to the basis points per annum at the indicated level of the ratio of
Consolidated Total Indebtedness to Cash Flow in the Revolving Credit Pricing
Grid on Schedule 1.1(A) below the heading "Standby Letter of Credit Fee," which
Standby Letter of Credit Fee shall be computed in accordance with the parameters
set forth on Schedule 1.1(A), and (ii) with respect to all Letters of Credit, to
the Agent for its own account and to Chase Manhattan Bank Delaware a fronting
fee as described in their respective fee letters, all of which fees shall be
computed on the average daily Letters of Credit Outstanding (as Commercial
Letters of Credit, Standby Letters of Credit, or both, as the case may be, and
in each case computed on the basis of a year of 360 days for the actual number
of days elapsed), and shall be payable quarterly in arrears commencing with the
first Business Day of each January, April, July and October following issuance
of each Letter of Credit and on the Revolving Credit Expiration Date. The
Borrower shall also pay to each Issuing Bank for such Issuing Bank's sole
account such Issuing Bank's then in effect customary fees and administrative
expenses payable with respect to the Letters of Credit as such Issuing Bank may
generally charge or incur from time to time in connection with the issuance,
maintenance, modification (if any), assignment or transfer (if any),
negotiation, and administration of letters of credit.

Disbursements, Reimbursement.

Immediately upon the issuance of each Letter of Credit and immediately upon
         execution of this Agreement with respect to the Letters of Credit
         listed on Schedules 2.9.1(A) and 2.9.1(B), each Revolving Credit Bank
         shall be deemed to, and hereby irrevocably and unconditionally agrees
         to, purchase from the Issuing Bank a participation in such Letter of
         Credit and each drawing thereunder in an amount equal to such Bank's
         Ratable Share of the maximum amount available to be drawn under such
         Letter of Credit and the amount of such drawing, respectively.

In the event of any request for a drawing under a Letter of Credit by the
         beneficiary or transferee thereof, the Issuing Bank will promptly
         notify the Borrower and the Agent. Provided that it shall have received
         such notice, the Borrower shall reimburse the Issuing Bank (such
         obligation to reimburse the Issuing Bank shall sometimes be referred to
         as a "Reimbursement Obligation") prior to 12:00 noon, New York time, on
         each date that an amount is paid by the Issuing Bank under any Letter
         of Credit (each such date, a "Drawing Date") in an amount equal to the
         Dollar Equivalent of the amount so paid by the Issuing Bank. In the
         event the Borrower fails to reimburse the Issuing Bank for the full
         amount of any drawing under any Letter of Credit by 12:00 noon, New
         York time, on the Drawing Date, the Agent will promptly notify each
         Revolving Credit Bank thereof, and the Borrower shall be deemed to have
         requested that Revolving Credit Loans in the Dollar Equivalent of the
         amount paid by the Issuing Bank under the Letter of Credit be made by
         the Revolving Credit Banks under the Base Rate Option to be disbursed
         on the Drawing Date under such Letter of Credit, subject to the amount
         of the



                                      -27-
<PAGE>   40


         unutilized portion of the Revolving Credit Commitment and subject to
         the conditions set forth in Section 7.2 other than any notice
         requirements. Any notice given by the Issuing Bank pursuant to this
         Section 2.9.3.2 may be oral if immediately confirmed in writing,
         provided that the lack of such an immediate confirmation shall not
         affect the conclusiveness or binding effect of such notice.

In consideration of its participation in each Letter of Credit, as set forth at
         Section 2.9.3.1, each Revolving Credit Bank shall upon any notice
         pursuant to Section 2.9.3.2 make available to the Issuing Bank an
         amount in immediately available funds equal to its Ratable Share of the
         Dollar Equivalent of the amount paid by the Issuing Bank under the
         Letter of Credit, whereupon the participating Banks shall (subject to
         Section 2.9.3.4) each be deemed to have made a Revolving Credit Loan
         under the Base Rate Option to the Borrower in that amount, if such Loan
         may be made, or each of the participating Banks shall be deemed to have
         funded its participation as provided below at Section 2.9.3.4. If any
         Bank so notified fails to make available to the Issuing Bank for the
         account of the Issuing Bank the amount of such Bank's Ratable Share of
         such amount by no later than 2:00 p.m., New York time, on the Drawing
         Date, then interest shall accrue on such Bank's obligation to make such
         payment, from the Drawing Date to the date on which such Bank makes
         such payment (i) at a rate per annum equal to the Federal Funds
         Effective Rate during the first three days following the Drawing Date
         and (ii) at a rate per annum equal to the rate applicable to Loans
         under the Revolving Credit Base Rate Option on and after the fourth day
         following the Drawing Date. The Issuing Bank will promptly give notice
         to the Agent of the occurrence of the Drawing Date and the Agent shall
         notify the Banks, but failure of the Issuing Bank or the Agent to give
         any such notice on the Drawing Date or in sufficient time to enable any
         Bank to effect such payment on such date shall not relieve such Bank
         from its obligation under this Section 2.9.3.3.

With respect to any unreimbursed drawing that is not converted into Revolving
         Credit Loans under the Base Rate Option to the Borrower in whole or in
         part as contemplated by Section 2.9.3.2, because of the Borrower's
         failure to satisfy the conditions set forth in Section 7.2 other than
         any notice requirements or for any other reason, the Borrower shall be
         deemed to have incurred from the Issuing Bank a Letter of Credit
         Borrowing in the Dollar Equivalent of the amount of such drawing. Such
         Letter of Credit Borrowing shall be due and payable on demand (together
         with interest) and shall bear interest at the rate per annum applicable
         to the Revolving Credit Loans under the Base Rate Option; for purposes
         of determining the available Revolving Credit Commitments of the Banks
         at any time, each outstanding Letter of Credit Borrowing shall be
         deemed to have utilized the Revolving Credit Commitments of the Banks
         pro rata in accordance with such respective Revolving Credit
         Commitments. Each Bank's payment to the Issuing Bank pursuant to
         Section 2.9.3.3 shall be deemed to be a payment in respect of its
         participation in such Letter of Credit Borrowing and shall constitute a
         Participation Advance from such Bank in satisfaction of its
         participation obligation under this Section 2.9.3.

Repayment of Participation Advances.

Upon (and only upon) receipt by the Issuing Bank for its account of immediately
         available funds from the Borrower (i) in reimbursement of any payment
         made by the Issuing Bank under the Letter of Credit with respect to
         which any Bank has made a Participation Advance to the Issuing Bank, or
         (ii) in payment of interest on such a payment made by the Issuing Bank
         under such a Letter of Credit, the Issuing Bank will pay to each
         Revolving Credit Bank, in the same funds as those received by the
         Issuing Bank, the amount of such Bank's Ratable Share of such funds,
         except the Issuing Bank shall retain the amount of the Ratable Share of
         such funds of any Bank that did not make a Participation Advance in
         respect of such payment by the Issuing Bank.



                                      -28-
<PAGE>   41


If the Issuing Bank is required at any time to return to any Loan Party, or to
         a trustee, receiver, liquidator, custodian, or any official in any
         Insolvency Proceeding, any portion of the payments made by any Loan
         Party to the Issuing Bank pursuant to Section 2.9.4.1 in reimbursement
         of a payment made under the Letter of Credit or interest or fee
         thereon, each Revolving Credit Bank shall, on demand of the Issuing
         Bank, forthwith return to the Issuing Bank the amount of its Ratable
         Share of any amounts so returned by the Issuing Bank plus interest
         thereon from the date such demand is made to the date such amounts are
         returned by such Bank to the Issuing Bank, at a rate per annum equal to
         the Federal Funds Effective Rate in effect from time to time.

Documentation.

                  Each Loan Party agrees to be bound by the terms of the Issuing
Bank's application and agreement for letters of credit and the Issuing Bank's
written regulations and customary practices relating to letters of credit,
though the Issuing Bank's interpretation may be different from such Loan Party's
own interpretation. In the event of a conflict between such application or
agreement and this Agreement, this Agreement shall govern. It is understood and
agreed that, except in the case of gross negligence or willful misconduct, the
Issuing Bank shall not be liable for any error, negligence, or mistakes, whether
of omission or commission, in following any Loan Party's instructions or those
contained in the Letters of Credit or any modifications, amendments, or
supplements thereto.

Intentionally Omitted.

Nature of Participation and Reimbursement Obligations.

                  Each Revolving Credit Bank's obligation in accordance with
this Agreement to make the Revolving Credit Loans or Participation Advances, as
contemplated by Section 2.9.3, as a result of a drawing under a Letter of
Credit, and the Obligations of the Borrower to reimburse the Issuing Bank upon a
draw under a Letter of Credit, shall be absolute, unconditional, and
irrevocable, and shall be performed strictly in accordance with the terms of
this Section 2.9 under all circumstances, including the following circumstances:

                           (i) any set-off, counterclaim, recoupment, defense,
or other right which such Bank may have against the Issuing Bank, the Borrower,
or any other Person for any reason whatsoever;

                           (ii) the failure of any Loan Party or any other
Person to comply, in connection with a Letter of Credit Borrowing, with the
conditions set forth in Sections 2.1, 2.5, 2.6, or 7.2 or as otherwise set forth
in this Agreement for the making of a Revolving Credit Loan, it being
acknowledged that such conditions are not required for the making of a Letter of
Credit Borrowing and the obligation of the Banks to make Participation Advances
under Section 2.9.3;

                           (iii) any lack of validity or enforceability of any
Letter of Credit;

                           (iv) the existence of any claim, set-off, defense, or
other right which any Loan Party or any Bank may have at any time against a
beneficiary or any transferee of any Letter of Credit (or any Persons for whom
any such transferee may be acting), the Issuing Bank or any Bank or any other
Person or, whether in connection with this Agreement, the transactions
contemplated herein, or any unrelated transaction (including any underlying
transaction between any Loan Party or Subsidiaries of a Loan Party and the
beneficiary for which any Letter of Credit was procured);



                                      -29-
<PAGE>   42


                           (v) any draft, demand, certificate, or other document
presented under any Letter of Credit proving to be forged, fraudulent, invalid,
or insufficient in any respect or any statement therein being untrue or
inaccurate in any respect even if the Issuing Bank has been notified thereof;

                           (vi) payment by the Issuing Bank under any Letter of
Credit against presentation of a demand, draft, or certificate or other document
which does not comply with the terms of such Letter of Credit;

                           (vii) any adverse change in the business, operations,
properties, assets, condition (financial or otherwise), or prospects of any Loan
Party or Subsidiaries of a Loan Party;

                           (viii) any breach of this Agreement or any other Loan
Document by any party thereto;

                           (ix) the occurrence or continuance of an Insolvency
Proceeding with respect to Borrower or any Subsidiary of Borrower;

                           (x) the fact that an Event of Default or a Potential
Default shall have occurred and be continuing;

                           (xi) the fact that the Revolving Credit Expiration
Date shall have passed or this Agreement or the Commitments hereunder shall have
been terminated; and

                           (xii) any other circumstance or happening whatsoever,
whether or not similar to any of the foregoing.

Indemnity.

                  In addition to amounts payable as provided in Section 10.5,
the Borrower hereby agrees to protect, indemnify, pay, and save harmless the
Issuing Bank from and against any and all claims, demands, liabilities, damages,
losses, costs, charges, and expenses (including reasonable fees, expenses, and
disbursements of counsel and allocated costs of internal counsel) which the
Issuing Bank may incur or be subject to as a consequence, direct or indirect, of
(i) the issuance of any Letter of Credit, other than as a result of (A) the
gross negligence or willful misconduct of the Issuing Bank as determined by a
final judgment of a court of competent jurisdiction or (B) subject to the
following clause (ii), the wrongful dishonor by the Issuing Bank of a proper
demand for payment made under any Letter of Credit, or (ii) the failure of the
Issuing Bank to honor a drawing under any such Letter of Credit as a result of
any act or omission, whether rightful or wrongful, of any present or future de
jure or de facto government or governmental authority (all such acts or
omissions herein called "Governmental Acts").

Liability for Acts and Omissions.

                  As between any Loan Party and the Issuing Bank, such Loan
Party assumes all risks of the acts and omissions of, or misuse of the Letters
of Credit by, the respective beneficiaries of such Letters of Credit. In
furtherance and not in limitation of the foregoing, the Issuing Bank shall not
be responsible for: (i) the form, validity, sufficiency, accuracy, genuineness,
or legal effect of any document submitted by any party in connection with the
application for an issuance of or any documents presented under any such Letter
of Credit, even if it should in fact prove to be in any or all respects invalid,



                                      -30-
<PAGE>   43


insufficient, inaccurate, fraudulent, or forged (even if the Issuing Bank shall
have been notified thereof); (ii) the validity or sufficiency of any instrument
transferring or assigning or purporting to transfer or assign any such Letter of
Credit or the rights or benefits thereunder or proceeds thereof, in whole or in
part, which may prove to be invalid or ineffective for any reason; (iii) the
failure of the beneficiary of any such Letter of Credit, or any other party to
which such Letter of Credit may be transferred, to comply fully with any
conditions required in order to draw upon such Letter of Credit or any other
claim of any Loan Party against any beneficiary of such Letter of Credit, or any
such transferee, or any dispute between or among any Loan Party and any
beneficiary of any Letter of Credit or any such transferee; (iv) errors,
omissions, interruptions, or delays in transmission or delivery of any messages,
by mail, cable, telegraph, telex, or otherwise, whether or not they be in
cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay
in the transmission or otherwise of any document required in order to make a
drawing under any such Letter of Credit or of the proceeds thereof; (vii) the
misapplication by the beneficiary of any such Letter of Credit of the proceeds
of any drawing under such Letter of Credit; or (viii) any consequences arising
from causes beyond the control of the Issuing Bank, including any Governmental
Acts, and none of the above shall affect or impair, or prevent the vesting of,
any of the Issuing Bank's rights or powers hereunder. Nothing in the preceding
sentence shall relieve the Issuing Bank from liability for the Issuing Bank's
gross negligence or willful misconduct in connection with actions or omissions
described in such clauses (i) through (viii) of such sentence.

                  In furtherance and extension and not in limitation of the
specific provisions set forth above, any action taken or omitted by the Issuing
Bank under or in connection with the Letters of Credit issued by it or any
documents and certificates delivered thereunder, if taken or omitted in good
faith (as such term is applicable to Letters of Credit pursuant to the
applicable Uniform Commercial Code), shall not put the Issuing Bank under any
resulting liability to the Borrower or any Bank.

                  In the event that the jurisdiction referred to in Section 11.8
adopts revisions to Article 5 of its Uniform Commercial Code which are
inconsistent with the provisions of this Section 2.9, the Loan Parties shall
upon the request of Agent agree to a modification of the provisions of this
Section 2.9 that is consistent with the intent hereof and permissible under such
Article 5 as revised.

Extension by Banks of the Expiration Date.

Requests; Approval by All Banks.

                  Upon or promptly after delivery by the Borrower of the annual
financial statements to be provided under Section 8.3.2 for the fiscal year
ending December 31, 1999, or any subsequent fiscal year, the Borrower may
request a one (1) year extension of the Revolving Credit Expiration Date by
written notice to the Banks, and the Banks agree to respond to the Borrower's
request for an extension within ninety (90) days following receipt of the
request; provided, however, that the failure of any Bank to respond within such
time period shall not in any manner constitute an agreement by such Bank to
extend the Revolving Credit Expiration Date. If all Banks elect to extend, the
Revolving Credit Expiration Date shall be extended for a period of one (1) year,
subject to the execution of reasonable and appropriate documentation thereof. If
one or more Banks decline to extend or do not respond to Borrower's request, the
provisions of Section 2.10.2 shall apply. Borrower may request successive
extensions by providing the extension request along with the audited financial
statement for the prior year in the manner set forth immediately above in this
Section 2.10.1 each respective year.



                                      -31-
<PAGE>   44


Approval by Required Banks.

                  In the event that one or more Banks do not agree to extend the
Revolving Credit Expiration Date or do not respond to Borrower's request for an
extension within the time required under Section 2.10.1 (each a "Bank to be
Terminated"), but the Required Banks agree to such extension within such time
then, the Banks which have agreed to such extension within the time required
under Section 2.10.1 (each an "Extending Bank") may, with the prior written
approval of the Borrower and the Agent, arrange to have one or more other banks
(each an "Assignee Bank") purchase all of the outstanding Loans, if any, of the
Bank to be Terminated and succeed to and assume the Commitments and all other
rights, interests, and obligations of the Bank to be Terminated under this
Agreement and the other Loan Documents (other than a Hedge Agreement). Any such
purchase and assumption shall be (1) pursuant to an Assignment and Assumption
Agreement, (2) subject to and in accordance with Section 11.11, and (3) if any
Committed Loans are outstanding under the Committed Loan Euro-Rate Option or if
any Bid Loans are outstanding to such Bank to be Terminated, scheduled to take
effect (to the extent of the Extending Banks' best efforts) on the last day of
the Interest Period with respect to the majority of such Loans. The Borrower
shall pay all amounts due and payable to the Bank to be Terminated on the
effective date of such Assignment and Assumption Agreement, including principal,
interest, fees, costs, and amounts, if any, owing under Section 5.6. In the
event that the Agent shall become a Bank to be Terminated, the provisions of
this Section 2.10 shall be subject to Section 10.14. In the event that the Loans
and Commitments of a Bank to be Terminated are not fully assigned and assumed
pursuant to this Section 2.10.2 on or before December 1 of such year, then the
Revolving Credit Expiration Date shall not be extended for any Bank.

Swingline Loans.

Swingline Commitment.

                  On the terms and subject to the conditions and relying upon
the representations and warranties herein set forth, the Swingline Bank agrees
to make loans (as described in this Section 2.11.1, "Swingline Loans") to the
Borrower at any time and from time to time on and after the date hereof to the
earlier of the Revolving Credit Expiration Date or the termination of the
Revolving Credit Commitments in accordance with the terms hereof, in an
aggregate principal amount at any time outstanding, after giving effect to any
Swingline Loan requested by Borrower, that will not result in (i) the aggregate
amount of all Swingline Loans outstanding exceeding $10,000,000, (ii) the
aggregate amount of all Revolving Credit Loans, Swingline Loans, and Bid Loans
outstanding plus the Letters of Credit Outstanding exceeding the aggregate
amount of the Revolving Credit Commitments then existing of the Banks, or (iii)
the aggregate outstanding amount of all Revolving Credit Loans, Convertible
Revolving Credit Loans, Swingline Loans, and Bid Loans plus the Letters of
Credit Outstanding exceeding the aggregate amount of the Revolving Credit
Commitments and Convertible Revolving Credit Commitments then existing of the
Banks. Each Swingline Loan shall be in a principal amount that is an integral
multiple of $100,000. The Swingline Commitment may be terminated or reduced from
time to time as provided herein. Within the foregoing limits and subject to the
terms, conditions and limitations set forth herein, the Borrower may borrow, pay
or repay and reborrow Swingline Loans hereunder. The Swingline Loans shall be
evidenced by a promissory note of Borrower in favor of the Swingline Bank
substantially in the form of Exhibit 1.1(S).

Swingline Loans.

                  The Borrower shall notify the Agent by telephone (promptly
confirmed in writing), not later than 12:00 (noon), New York City time, on the
date of a proposed Swingline Loan. Such notice



                                      -32-
<PAGE>   45


shall be delivered on a Business Day, shall be irrevocable and shall refer to
this Agreement and shall specify the requested date (which shall be a Business
Day), amount of such Swingline Loan, and whether such Swingline Loan shall be
subject to the Base Rate or the Cost of Funds Rate. The Agent will promptly
advise the Swingline Bank of any notice received from the Borrower pursuant to
this SubSection 2.11.2. The Swingline Bank will make each Swingline Loan
available to the Borrower by means of a credit to a general deposit account or
as otherwise designated by the Borrower by telephone (promptly confirmed in
writing) by 3:00 p.m. on the date such Swingline Loan is so requested. The Agent
and Swingline Bank may rely on the authority of any individual making such a
telephonic request or giving such telephonic direction without the necessity of
receipt of written confirmation.

Prepayment.

                  The Borrower shall have the right at any time and from time to
time to prepay any Swingline Loan, in whole or in part, upon giving telephonic
notice (promptly confirmed in writing) to the Swingline Bank and to the Agent
before 2:00 p.m., New York City time on the date of prepayment at the Swingline
Bank's address for notices specified on Schedule 1.1(B). Any prepayment in part
of a Swingline Loan shall be in an amount that is an integral multiple of
$100,000. All principal payments of Swingline Loans shall be accompanied by
accrued interest on the principal amount being repaid to but excluding the date
of payment. All outstanding Swingline Loans shall be due and payable on the
Revolving Credit Expiration Date.

Interest.

                  Each Swingline Loan shall be subject to, at the option of
Borrower, either the Cost of Funds Rate or the Base Rate Option, and the
provisions of Section 4.3, and shall bear interest at a rate per annum equal to
the Base Rate or Cost of Funds Rate plus the Applicable Margin, in effect from
time to time.

Participations.

                  The Swingline Bank may by written notice given to the Agent
not later than 12:00 (noon), New York City time, on any Business Day require the
Revolving Credit Banks to acquire participations in all or a portion of the
Swingline Loans outstanding. Such notice shall specify the aggregate amount of
Swingline Loans in which Revolving Credit Banks shall participate. The Agent
will, promptly upon receipt of such notice, give notice to each Revolving Credit
Bank, specifying in such notice such Bank's Ratable Share of such Swingline Loan
or Loans. In consideration and in furtherance of the foregoing, each Revolving
Credit Bank hereby absolutely and unconditionally agrees, upon receipt of notice
as provided above, to pay to the Agent, for the account of the Swingline Bank,
such Revolving Credit Bank's Ratable Share of such Swingline Loan or Loans. Each
Bank acknowledges and agrees that its obligation to acquire participations in
Swingline Loans pursuant to this Section 2.11.5 is absolute and unconditional
and shall not be affected by any circumstance whatsoever, including the
occurrence and continuance of a Potential Default or an Event of Default, and
that each such payment shall be made without any offset, abatement, withholding
or reduction whatsoever. Each Revolving Credit Bank shall comply with its
obligation under this Section by wire transfer to Agent of immediately available
funds not later than 2:00 p.m. New York City time, and the Agent shall promptly
credit the amounts so received to the account of the Swingline Bank. The Agent
shall notify the Borrower of any participations in any Swingline Loan acquired
pursuant to this Section and thereafter payments in respect of such Swingline
Loan shall be made to the Agent and not to the Swingline Bank. Any amounts
received by the Swingline



                                      -33-
<PAGE>   46


Bank from the Borrower (or other party on behalf of the Borrower) in respect of
a Swingline Loan after receipt by the Swingline Bank of the proceeds of a sale
of participations therein shall be promptly remitted to the Agent; any such
amounts received by the Agent shall be promptly remitted by the Agent to the
Banks that shall have made their payments pursuant to this Section and to the
Swingline Bank, as their interests may appear. The purchase of participations in
a Swingline Loan pursuant to this Section 2.11.5 shall not relieve the Borrower
(or other party liable for obligations of the Borrower) of its default in
respect of the payment thereof.

CONVERTIBLE REVOLVING CREDIT FACILITY

Convertible Revolving Credit Commitments.

         (a) Subject to the terms and conditions hereof and relying upon the
representations and warranties herein set forth, each Bank severally agrees to
make Convertible Revolving Credit Loans to the Borrower at any time or from time
to time on or after the date hereof to the Convertible Revolving Credit
Expiration Date, provided that no Convertible Revolving Credit Loan shall be
made unless the aggregate amount of all Revolving Credit Loans outstanding
equals at least $190,000,000, and further provided that after giving effect to
each such Loan the aggregate amount of Convertible Revolving Credit Loans from
such Bank shall not exceed such Bank's Convertible Revolving Credit Commitment,
and provided further that in no event shall the Convertible Revolving Credit
Expiration Date occur later than the Revolving Credit Expiration Date. Within
such limits of time and amount and subject to the other provisions of this
Agreement, the Borrower may borrow, repay and reborrow pursuant to this Section
3.1. All outstanding Convertible Revolving Credit Loans shall be due and payable
on the Convertible Revolving Credit Expiration Date.

         (b) Each Bank shall be obligated to participate in each request for
Convertible Revolving Credit Loans pursuant to Section 3.2 in accordance with
its Ratable Share. The aggregate of each Bank's Convertible Revolving Credit
Loans outstanding hereunder to the Borrower at any time shall never exceed its
Convertible Revolving Credit Commitment. The obligations of each Bank hereunder
are several and not joint. The failure of any Bank to perform its obligations
hereunder shall not affect the Obligations of the Borrower to any other party
nor shall any other party be liable for the failure of such Bank to perform its
obligations hereunder. The Banks shall have no obligation to make Convertible
Revolving Credit Loans hereunder on or after the Convertible Revolving Credit
Expiration Date.

Convertible Revolving Credit Loan Requests.

         Except as otherwise provided herein, the Borrower may from time to time
prior to the Convertible Revolving Credit Expiration Date request the Banks to
make Convertible Revolving Credit Loans, or renew or convert the Interest Rate
Option applicable to existing Convertible Revolving Credit Loans pursuant to
Section 4.2, by delivering to the Agent at its Principal Office in New York, (i)
not later than 12:00 noon, New York time, three (3) Business Days prior to the
proposed Borrowing Date with respect to the making of Convertible Revolving
Credit Loans to which the Euro-Rate Option applies or prior to the conversion to

than 12:00 (noon), New York time, on the Business Day of either the proposed
Borrowing Date with respect to the making of a Convertible Revolving Credit Loan
to which the Base Rate Option applies or the last day of the preceding Committed
Loan Interest Period with respect to the conversion of an Interest Rate Option
to the Base Rate Option for any such Loan, a duly completed Committed Loan
Request therefor substantially in the form of Exhibit 2.5 or a Committed Loan
Request by telephone immediately



                                      -34-
<PAGE>   47


confirmed in writing by letter, facsimile, or telex in the form of such Exhibit,
it being understood that the Agent may rely on the authority of any individual
making such a telephonic request without the necessity of receipt of such
written confirmation. Each Loan Request shall be irrevocable and shall specify
(i) the proposed Borrowing Date; (ii) the aggregate amount of the proposed
Convertible Revolving Credit Loans comprising each Borrowing Tranche, which
shall be in integral multiples of $1,000,000 and not less than $2,500,000 for
each Borrowing Tranche to which the Euro-Rate Option applies and in integral
multiples of $500,000 and not less than the lesser of $1,000,000 or the maximum
amount available for Borrowing Tranches to which the Base Rate Option applies;
(iii) whether Committed Loan Euro-Rate Option or Base Rate Option shall apply to
the proposed Convertible Revolving Credit Loans comprising the applicable
Borrowing Tranche; and (iv) in the case of a Borrowing Tranche to which the
Committed Loan Euro-Rate Option applies, an appropriate Committed Loan Interest
Period for the Convertible Revolving Credit Loans comprising such Borrowing
Tranche.

Making Convertible Revolving Credit Loans.

         The Agent shall, promptly after receipt by it of a Loan Request
pursuant to Section 3.2, notify the Banks of its receipt of such Loan Request
specifying: (i) the proposed Borrowing Date and the time and method of
disbursement of the Convertible Revolving Credit Loans requested thereby; (ii)
the amount and type of each such Convertible Revolving Credit Loan and the
applicable Interest Period (if any); and (iii) the apportionment among the Banks
of such Convertible Revolving Credit Loans as determined by the Agent in
accordance with Section 3.1(b). Each Bank shall remit the principal amount of
each Convertible Revolving Credit Loan to the Agent at its Principal Office in
New York such that the Agent is able to, and the Agent shall, to the extent the
Banks have made funds available to it for such purpose and subject to Section
7.2, fund such Convertible Revolving Credit Loans to the Borrower in U.S.
Dollars and immediately available funds at the Principal Office in New York City
prior to 2:00 p.m., New York time, on the applicable Borrowing Date, provided
that if any Bank fails to remit such funds to the Agent in a timely manner, the
Agent may elect in its sole discretion to fund with its own funds the
Convertible Revolving Credit Loans of such Bank on such Borrowing Date, and such
Bank shall be subject to the repayment obligation in Section 10.16.

Extension by Banks of the Convertible Revolving Credit Expiration Date.

Requests; Approval by All Banks or Required Banks; Optional Conversion to
     Term Loans for Non-Agreeing Banks.

                  (a) No earlier than sixty (60) days and no later than thirty
(30) days prior to the then applicable Convertible Revolving Credit Expiration
Date, the Borrower may request a 364-day extension of the Convertible Revolving
Credit Expiration Date by written notice to the Agent. Agent shall promptly
notify the Banks of such request. No later than fifteen (15) days prior to the
then applicable Convertible Revolving Credit Expiration Date, each Bank shall
respond to the Agent in writing as to whether or not it agrees to the Borrower's
request for such extension; provided, however, that the failure of any Bank to
respond within such time period shall not in any manner constitute an agreement
by such Bank to extend the Convertible Revolving Credit Expiration Date.

                  (b) If all Banks elect to extend the then applicable
Convertible Revolving Credit Expiration Date, the Agent shall so notify the
Banks promptly and shall so notify the Borrower promptly, but in no event
earlier than thirty (30) days prior to the then applicable Convertible Revolving
Credit Expiration Date, that such Convertible Revolving Credit Expiration Date
shall be extended for an



                                      -35-
<PAGE>   48


additional period of 364 days. Borrower hereby agrees to execute such amendments
and modifications to the Loan Documents, prior to the extension of the
Convertible Revolving Credit Expiration Date, as Agent shall reasonably request
to evidence and govern the extension of such date.

                  (c) In the event that the Required Banks, but less than all of
the Banks, shall agree to an extension of the Convertible Revolving Credit
Expiration Date in accordance with this Section 3.4.1 (and in addition to the
provisions of Section 5.4.2), the Agent shall so notify the Banks promptly and
shall so notify the Borrower promptly, but in no event earlier than thirty (30)
days prior to the then applicable Convertible Revolving Credit Expiration Date,
and: (i) the Convertible Revolving Credit Commitments of those Banks not
agreeing to an extension of the Convertible Revolving Credit Expiration Date
(the "Non-Agreeing Banks") shall be terminated on the Convertible Revolving
Credit Expiration Date (without giving effect to the extension thereof) and all
Convertible Revolving Credit Loans owing to the Non-Agreeing Banks together with
all interest thereon and costs and expenses related thereto shall be due and
payable on such Convertible Revolving Credit Expiration Date except to the
extent that Borrower has elected, by written notice received by the Agent no
later than five (5) days prior to the Convertible Revolving Credit Expiration
Date, to convert all or any portion of the Convertible Revolving Credit Loans of
the Non-Agreeing Banks to a term loan of one year's duration from the date of
the Convertible Revolving Credit Expiration Date with interest payable thereon
and rights of prepayment permitted with respect thereto in the manner
established hereby for Convertible Revolving Credit Loans and with principal
amounts thereunder amortizing, if at all, during such one (1) year term as
Borrower shall elect in such notice of conversion; provided that the Convertible
Revolving Credit Loans of the Non-Agreeing Banks which are converted to term
loans shall be amortized in the same manner, and, to the extent that less than
the full aggregate amount of Convertible Revolving Credit Loans of the Banks are
to be so converted then Borrower shall convert each and every Non-Agreeing
Bank's Convertible Revolving Credit Loans on a pro rata basis (ii) the
Convertible Revolving Credit Commitments of the Banks agreeing to an extension
of the Convertible Revolving Credit Expiration Date (the "Agreeing Banks") shall
be extended for an additional period of 364 days, and (iii) none of the Agreeing
Banks shall be required to increase its Convertible Revolving Credit Commitment.
Borrower hereby agrees to execute such amendments and modifications to the Loan
Documents, prior to any extension of the Convertible Revolving Credit Expiration
Date, as Agent shall reasonably request to evidence and govern the extension of
such date and the term loans, if any, arising under this Section 3.4.1.

Failure of Required Banks to Extend; Optional Conversion to Term Loan.

                  In the event that less than the Required Banks shall agree to
an extension of the Convertible Revolving Credit Expiration Date in accordance
with Section 3.4.1 (subject, however, to Section 5.4.2), the Agent shall
promptly so notify the Borrower and the Banks and the Convertible Revolving
Credit Commitments shall be terminated on the Convertible Revolving Credit
Expiration Date and all Convertible Revolving Credit Loans, together with all
interest thereon and costs and expenses related thereto, shall be due and
payable on the Convertible Revolving Credit Expiration Date, unless Borrower has
elected, by written notice received by the Agent no later than five (5) days
prior to the Convertible Revolving Credit Expiration Date (which notice Agent
shall promptly forward to the Banks), to convert all Convertible Revolving
Credit Loans outstanding on the Convertible Revolving Credit Expiration Date to
a term loan of one year's duration from the date of the Convertible Revolving
Credit Expiration Date with interest payable thereon and rights of prepayment
permitted with respect thereto in the manner established hereby for Convertible
Revolving Credit Loans and with principal amounts thereunder amortizing, if at
all, during such one (1) year term as Borrower shall elect in such notice of


                                      -36-
<PAGE>   49


conversion (the "Term Loan"). Any failure of the Agent or any Bank to notify any
party hereto under any of this Section 3.4 or otherwise that the Convertible
Revolving Credit Expiration Date will not be extended shall not constitute a
commitment or agreement of any nature to extend such date. Borrower hereby
agrees to execute such amendments and modifications to the Loan Documents, prior
to the Convertible Revolving Credit Expiration Date, as Agent shall reasonably
request to evidence and govern the Term Loan.

INTEREST RATES

Interest Rate Options.

         The Borrower shall pay interest in respect of the outstanding unpaid
principal amount of the Committed Loans (other than with respect to the
Swingline Loans which are addressed in Section 2.11.4) as selected by it from
the Base Rate Option or Revolving Credit Euro-Rate Option or Convertible
Revolving Credit Euro-Rate Option set forth below applicable to the type of
Committed Loans, it being understood that, subject to the provisions of this
Agreement, the Borrower may select different Interest Rate Options and different
Interest Periods to apply simultaneously to various of the Committed Loans
comprising different Borrowing Tranches and may convert to or renew one or more
Interest Rate Options with respect to all or any portion of the Committed Loans
comprising any Borrowing Tranche, provided that there shall not be at any one
time outstanding more than twelve (12) Borrowing Tranches in the aggregate among
all of the Committed Loans. If at any time the designated rate applicable to any
portion of a Committed Loan made by any Bank exceeds such Bank's highest lawful
rate, the rate of interest on such Bank's Committed Loan shall be limited to
such Bank's highest lawful rate.

Revolving Credit Interest Rate Options.

The Borrower shall have the right to select from the following Interest Rate
         Options applicable to the Revolving Credit Loans:

                           (i) Revolving Credit Base Rate Option: A fluctuating
rate per annum (computed on the basis of a year of 360 days for the actual
number of days elapsed) equal to the Base Rate, such interest rate to change
automatically from time to time effective as of the effective date of each
change in the Base Rate; or

                           (ii) Revolving Credit Euro-Rate Option: A rate per
annum (computed on the basis of a year of 360 days for the actual number of days
elapsed) equal to the Euro-Rate plus the Applicable Margin.

Convertible Revolving Credit Interest Rate Options.

                  The Borrower shall have the right to select from the following
Interest Rate Options applicable to the Convertible Revolving Credit Loans:

                  (i) Convertible Revolving Credit Base Rate Option: A
fluctuating rate per annum (computed on the basis of a year of 360 days for the
actual number of days elapsed) equal to the Base Rate, such interest rate to
change automatically from time to time effective as of the effective date of
each change in the Base Rate; or



                                      -37-
<PAGE>   50


                  (ii) Convertible Revolving Credit Euro-Rate Option: A rate per
annum (computed on the basis of a year of 360 days for the actual number of days
elapsed) equal to the Euro-Rate plus the Applicable Margin.

Rate Quotations.

                  The Borrower may call the Agent at the Principal Office of the
Agent in New York on or before the date on which a Committed Loan Request is to
be delivered to receive an indication of the rates then in effect, but it is
acknowledged that such projection shall not be binding on the Agent or the Banks
nor affect the rate of interest which thereafter is actually in effect when the
election is made.

Level of Fees and Interest Rates as of Closing; Change in Fees or Interest
     Rates.

                  Notwithstanding any other provision hereof, for the purpose
solely of determining the Applicable Margin, Applicable Revolving Credit
Commitment Fee, Applicable Convertible Revolving Credit Commitment Fee, Standby
Letter of Credit Fee, and Commercial Letter of Credit Fee, the ratio of
Consolidated Total Indebtedness to Cash Flow, calculated in accordance with the
terms of Section 8.2.15, shall be deemed to be 2.78 to 1.0 as of that Adjustment
Date which is applicable during the period commencing on the date hereof until
the next Adjustment Date.

                  The Applicable Margin, Applicable Revolving Credit Commitment
Fee, Applicable Convertible Revolving Credit Commitment Fee, Standby Letter of
Credit Fee, and Commercial Letter of Credit Fee shall be determined on the basis
of the ratio of Consolidated Total Indebtedness to Cash Flow, calculated in
accordance with the terms of Section 8.2.15, as of each Adjustment Date,
commencing with the Adjustment Date applicable as of the date hereof, and shall
remain in effect until the next Adjustment Date thereafter whereupon the
Applicable Margin, Applicable Revolving Credit Commitment Fee, Applicable
Convertible Revolving Credit Commitment Fee, Standby Letter of Credit Fee, and
Commercial Letter of Credit Fee shall be changed as necessary to reflect the
then existing ratio of Consolidated Total Indebtedness to Cash Flow, calculated
in accordance with the terms of Section 8.2.15, notwithstanding that such change
occurs during an Interest Period.

                  In the event the financial statements of the Borrower are not
delivered by the due date required by Section 8.3.1 or 8.3.2, the Applicable
Margin, Applicable Revolving Credit Commitment Fee, Applicable Convertible
Revolving Credit Commitment Fee, Standby Letter of Credit Fee, and Commercial
Letter of Credit Fee then in effect shall continue (subject to Section 4.3 as it
may apply as a result of any Event of Default from such failure to deliver
financial statements) until receipt by Agent of financial statements reflecting
that a different margin or fee is applicable as a result of a change in the
ratio of Consolidated Total Indebtedness to Cash Flow, provided, that if the
Applicable Margin, Applicable Revolving Credit Commitment Fee, Applicable
Convertible Revolving Credit Commitment Fee, Standby Letter of Credit Fee, or
Commercial Letter of Credit Fee is increased with respect to any period for
which the Borrower has already paid interest or fees, the Agent shall
recalculate the additional interest or fees due from the Borrower and shall,
within fifteen (15) Business Days after the receipt of such financial
statements, give the Borrower and the Banks notice of such recalculation
whereupon such additional interest and fees shall be due and payable by Borrower
to Agent for the benefit of the Banks in accordance with Section 4.1.4.1.

Any additional interest or fee due from the Borrower shall be paid to the Agent
         for the account of the Banks on the next date on which an interest or
         fee payment is due; provided, however, that if



                                      -38-
<PAGE>   51


         there are no Loans or Letters of Credit outstanding or if the Loans are
         due and payable or the Letters of Credit are to expire or be drawn upon
         within twenty (20) days, such additional interest or fee shall be paid
         promptly after receipt of written request for payment from the Agent.

Committed Loans Interest Periods.

         At any time when the Borrower shall select, convert to or renew a
Committed Loan Euro-Rate Option, the Borrower shall notify the Agent thereof at
its Principal Office in New York at least three (3) Business Days prior to the
effective date of such Euro-Rate Option by delivering a Loan Request. The notice
shall specify an interest period (the "Committed Loan Interest Period") during
which such Interest Rate Option shall apply, such Committed Loan Interest Period
to be one, two, three, or six Months (and nine or twelve Months if available to
all Banks at substantially the same cost to each). Notwithstanding the preceding
sentence, the following provisions shall apply to any selection of, renewal of,
or conversion to a Committed Loan Euro-Rate Option:

Ending Date and Business Day.

                  Any Committed Loan Interest Period which would otherwise end
on a date which is not a Business Day shall be extended to the next succeeding
Business Day unless such Business Day falls in the next calendar month, in which
case such Committed Loan Interest Period shall end on the directly preceding
Business Day;

Termination Before Expiration Date.

                  The Borrower shall not select, convert to or renew an Interest
Period, respectively, for any portion of the Revolving Credit Loans or
Convertible Revolving Credit Loans that would end after the Revolving Credit
Expiration Date or Convertible Revolving Credit Expiration Date; and

Renewals.

                  In the case of the renewal of a Committed Loan Euro-Rate
Option at the end of an Interest Period, the first day of the new Interest
Period shall be the last day of the preceding Interest Period, without
duplication in payment of interest for such day.

Interest After Default.

                  To the extent permitted by Law, upon the occurrence of an
Event of Default and until such time as such Event of Default shall have been
cured or waived:

Letter of Credit Fees, Interest Rate.

                  The Standby Letter of Credit Fees and the Commercial Letter of
Credit Fees and the rate of interest for each Loan otherwise applicable pursuant
to the provisions hereof shall be increased by 2.0% per annum; and

Other Obligations.

                  Each other Obligation (other than under a Hedge Agreement)
hereunder if not paid when due shall bear interest at a rate per annum equal to
the sum of the rate of interest applicable under the



                                      -39-
<PAGE>   52


Revolving Credit Base Rate Option plus an additional 2.0% per annum from the
time such Obligation becomes due and payable and until it is paid in full.

Acknowledgment.

                  The Borrower acknowledges that the increase in rates referred
to in this Section 4.3 reflects, among other things, that such Loans or other
amounts have become a substantially greater risk given their default status and
that the Banks are entitled to additional compensation for such risk; and all
such interest shall be payable by Borrower upon demand by Agent.

Euro-Rate Unascertainable; Illegality; Increased Costs; Deposits Not Available.

Unascertainable.

                  If, on any date on which a Euro-Rate would otherwise be
determined with respect to Committed Loans or Bid Loans, the Agent shall have
determined that:

                  (i)  adequate and reasonable means do not exist for
                       ascertaining such Euro-Rate, or

                  (ii) a contingency has occurred which materially and adversely
                       affects the London interbank eurodollar market relating
                       to the Euro-Rate,

then the Agent and the Banks shall have the rights specified in Section 4.4.3.

Illegality; Increased Costs; Deposits Not Available.

                  If at any time any Bank shall have determined that:

                  (i) the making, maintenance or funding of any Loan to which a
Euro-Rate Option applies has been made impracticable or unlawful by compliance
by such Bank in good faith with any Law or any interpretation or application
thereof by any Official Body or with any request or directive of any such
Official Body (whether or not having the force of Law), or

                  (ii) such Euro-Rate Option will not adequately and fairly
reflect the cost to such Bank of the establishment or maintenance of any such
Loan, or

                  (iii) after making all reasonable efforts, deposits of the
relevant amount in Dollars for the relevant Interest Period for a Loan to which
a Euro-Rate Option applies, respectively, are not available to such Bank with
respect to such Loan, in the London interbank market,

then the Agent and the Banks shall have the rights specified in Section 4.4.3.

Agent's and Bank's Rights.

                  In the case of any event specified in Section 4.4.1 above, the
Agent shall promptly so notify the Banks and the Borrower thereof, and in the
case of an event specified in Section 4.4.2 above, such Bank shall promptly so
notify the Agent at its Principal Office in New York and endorse a certificate
to such notice as to the specific circumstances of such notice, and the Agent
shall promptly send copies of such notice and certificate to the other Banks and
the Borrower. Upon such date as shall



                                      -40-
<PAGE>   53


be specified in such notice (which shall not be earlier than the date such
notice is given), the obligation of (A) the Banks, in the case of such notice
given by the Agent, or (B) such Bank, in the case of such notice given by such
Bank, to allow the Borrower to select, convert to, or renew a Euro-Rate Option
shall be suspended until the Agent shall have later notified the Borrower, or
such Bank shall have later notified the Agent, of the Agent's or such Bank's, as
the case may be, determination that the circumstances giving rise to such
previous determination no longer exist. If at any time the Agent makes a
determination under Section 4.4.1 and the Borrower has previously notified the
Agent of its selection of, conversion to, or renewal of a Euro-Rate Option and
such Interest Rate Option has not yet gone into effect, such notification shall
be deemed to provide for the termination of Borrower's Bid Loan request (without
penalty) for such Loans if the Borrower has requested Bid Loans under the Bid
Loan Euro-Rate Option and for the selection of, conversion to, or renewal of the
Base Rate Option otherwise available with respect to such Loans if the Borrower
has requested the Committed Loan Euro-Rate Option. If any Bank notifies the
Agent of a determination under Section 4.4.2, the Borrower shall, subject to the
Borrower's indemnification Obligations under Section 5.6.2 [Indemnity], as to
any Loan of the Bank to which a Euro-Rate Option applies, on the date specified
in such notice either convert such Loan to the Base Rate Option otherwise
available with respect to such Loan or prepay such Loan in accordance with
Section 5.4 [Voluntary Prepayments]. Absent due notice from the Borrower of
conversion or prepayment, such Loan shall automatically be converted to the Base
Rate Option otherwise available with respect to such Loan upon such specified
date.

Selection of Interest Rate Options.

                  If the Borrower fails to select a new Interest Period to apply
to any Borrowing Tranche of Committed Loans subject to the Committed Loan
Euro-Rate Option at the expiration of the existing Interest Period applicable to
such Borrowing Tranche in accordance with the provisions of Section 4.2, the
Borrower shall be deemed to have converted such Borrowing Tranche to the
Revolving Credit Base Rate Option or Convertible Revolving Credit Base Rate
Option, as applicable, commencing upon the last day of the existing Interest
Period.

PAYMENTS

Payments.

         All payments and prepayments to be made in respect of principal,
interest, fees, or other amounts due from the Borrower hereunder or in
connection herewith shall be payable prior to 2:00 p.m., New York time, on the
date when due without presentment, demand, protest, or notice of any kind, all
of which are hereby expressly waived by the Borrower, and without set-off,
counterclaim, or other deduction of any nature, and an action therefor shall
immediately accrue. Such payments shall be made to the Agent at its Principal
Office in New York, or at such location as Agent shall otherwise direct, for the
ratable accounts of the Banks with respect to the Loans (other than with respect
to Swingline Loans which, to the extent not participated to the Banks shall be
for the account of the Swingline Bank) and for the account of the lending Bank
with respect to the Bid Loans, in U.S. Dollars and in immediately available
funds, and the Agent shall promptly distribute such amounts to the Banks in
immediately available funds, provided that in the event payments are received by
2:00 p.m., New York time, by the Agent with respect to the Loans and such
payments are not distributed to the Banks on the same day received by the Agent,
the Agent shall pay the Banks the Federal Funds Effective Rate with respect to
the amount of such payments for each day held by the Agent and not distributed
to the Banks. The Agent's statement of account, ledger, or other relevant record
shall, in the absence of manifest error, be



                                      -41-
<PAGE>   54


conclusive as the statement of the amount of principal of and interest on the
Loans and other amounts owing under this Agreement.

Pro Rata Treatment of Banks.

         Each borrowing of Revolving Credit Loans or Convertible Revolving
Credit Loans shall be allocated to each Bank according to its Ratable Share
respectively of the Revolving Credit Commitments and the Convertible Revolving
Credit Commitments (irrespective of the amount of Bid Loans or Swingline Loans
outstanding), and each selection of, conversion to, or renewal of any Interest
Rate Option applicable to Revolving Credit Loans or Convertible Revolving Credit
Loans and each payment or prepayment by the Borrower with respect to principal
or interest on the Revolving Credit Loans or Convertible Revolving Credit Loans
or fees (except for the Agent's Fee, and the Bid Loan Processing Fee) or other
amounts due from the Borrower hereunder to the Banks with respect to the
Revolving Credit Loans or Convertible Revolving Credit Loans, shall (except as
provided in Section 4.4.3 in the case of an event specified in Section 4.4,
5.4.2 or 5.6) be made in proportion to the applicable Revolving Credit Loans or
Convertible Revolving Credit Loans outstanding from each Bank and, if no such
Loans are then outstanding from any Bank, in proportion to the Ratable Share of
each Bank. Each borrowing of a Bid Loan shall be made according to the
provisions in Section 2.8 hereof and each payment or prepayment by the Borrower
of principal, interest, fees, or other amounts with respect to Bid Loans shall
be made to the Banks in proportion to the amounts of such items due to such
Banks; borrowings of and payments on Swingline Loans shall be governed, inter
alia, by the terms of Section 2.11. Subject to Section 2.3, for purposes of
determining the available Revolving Credit Commitments of the Banks at any time,
each outstanding Bid Loan and each outstanding Swingline Loan shall be deemed to
have utilized the Revolving Credit Commitments of the Banks pro rata in
accordance with such respective Revolving Credit Commitments.

Interest Payment Dates.

         Interest on Committed Loans to which the Base Rate Option or Cost of
Funds Rate applies shall be due and payable in arrears on the first Business Day
of each January, April, July, and October, after the date hereof and on the
Revolving Credit Expiration Date or the Convertible Revolving Credit Expiration
Date with respect to Revolving Credit Loans or Convertible Revolving Credit
Loans, respectively, or upon acceleration of any Loan. Interest on Committed
Loans and Bid Loans to which the Euro-Rate Option applies and Bid Loans to which
the Bid Loan Fixed Rate Option applies shall be due and payable on the last day
of each Interest Period for those Loans and, if such Interest Period is longer
than three (3) Months, also at the end of each three (3) Month period within
such Interest Period, calculated from the commencement thereof. Interest on the
principal amount of each Loan or other monetary Obligation shall be due and
payable on demand after such principal amount or other monetary Obligation
becomes due and payable (whether on the stated maturity date, upon acceleration,
or otherwise).

Voluntary Prepayments; Reduction of Commitment.

Right to Prepay.

                  The Borrower shall have the right at its option from time to
time to prepay the Committed Loans and Bid Loans in whole or part without
premium or penalty (except as provided in Section 5.4.2 below or in Section
5.6):



                                      -42-
<PAGE>   55


                  (i) at any time with respect to any Committed Loan to which
the Base Rate Option or Cost of Funds Rate applies,

                  (ii) on the last day of the applicable Interest Period with
respect to Committed Loans to which a Euro-Rate Option applies, and

                  (iii) on the date specified in a notice by any Bank pursuant
to Section 4.4 with respect to any Committed Loan or Bid Loan to which a
Euro-Rate Option applies.

                  Whenever the Borrower desires to prepay any part of the
Committed Loans or Bid Loans, it shall provide a prepayment notice to the Agent
at its Principal Office in New York by 1:00 p.m. at least three (3) Business
Days prior to the date of prepayment with respect to Loans to which the
Euro-Rate Option applies and by 12:00 (noon) on the Business Day of prepayment
with respect to Loans to which the Base Rate Option or Cost of Funds Rate
applies setting forth the following information:

                           (x) the date, which shall be a Business Day, on which
                  the proposed prepayment is to be made;

                           (y) a statement indicating the application of the
                  prepayment between the Revolving Credit Loans and Convertible
                  Revolving Credit Loans and Swingline Loans and Bid Loans; and

                           (z) the total principal amount of such prepayment,
                  which shall not be less than $1,000,000 and in integral
                  multiples of $500,000 for Loans to which the Base Rate Option
                  applies (other than with respect to the minimum amount of
                  Swingline Loan prepayments which are addressed at Section
                  2.11.3) and which shall not be less than $2,500,000 and in
                  integral multiples of $1,000,000 for Loans to which the
                  Euro-Rate Option applies.

                  All prepayment notices shall be irrevocable. The principal
amount of the Committed Loans for which a prepayment notice is given, together
with interest on such principal amount, shall be due and payable on the date
specified in such prepayment notice as the date on which the proposed prepayment
is to be made. Except as provided in Section 4.4.3, if the Borrower prepays a
Committed Loan but fails to specify the applicable Borrowing Tranche which the
Borrower is prepaying, the prepayment shall be applied first to Committed Loans
to which the Base Rate Option applies, then to Loans to which the Committed Loan
Euro-Rate Option applies. Any prepayment hereunder shall be subject to the
Borrower's Obligation to indemnify the Banks under Section 5.6.2.

                  Borrower's rights and obligations with respect to prepayments
of the Term Loan shall be the same as set forth herein for Convertible Revolving
Credit Loans (except to the extent necessary to account for structural
differences between the nature of Committed Loans and the Term Loan).

Replacement of a Bank.

                  In the event any Bank (i) gives notice under Section 4.4 or
Section 5.6.1, (ii) does not fund Revolving Credit Loans, Convertible Revolving
Credit Loans or Bid Loans because the making of such Loans would contravene any
Law applicable to such Bank, (iii) does not approve any action as to which
consent of the Required Banks is requested by the Borrower and obtained
hereunder, (iv) does not



                                      -43-
<PAGE>   56


agree to an extension of the Convertible Revolving Credit Expiration Date in
accordance with Section 3.4.1 and, however, the Required Banks do so agree, or
(v) becomes subject to the control of an Official Body (other than normal and
customary supervision),

then the Borrower shall have the right at its option, with the consent of the
Agent, which shall not be unreasonably withheld, to prepay the Loans of such
Bank in whole, together with all interest accrued thereon, and terminate such
Bank's Commitment within thirty (30) days after an event described in Clause
(iv) directly above, or within ninety (90) days after (w) receipt of such Bank's
notice under Section 4.4 or 5.6.1, (x) the date such Bank has failed to fund
Revolving Credit Loans, Convertible Revolving Credit Loans or Bid Loans because
the making of such Loans would contravene Law applicable to such Bank, (y) the
date of obtaining the consent which such Bank has not approved, or (z) the date
such Bank became subject to the control of an Official Body, as applicable;
provided that the Borrower shall also pay to such Bank at the time of such
prepayment any amounts required under Section 5.6 and any accrued interest due
on such amount and any other fees and costs payable hereunder; provided,
however, that the Revolving Credit Loans, Convertible Revolving Credit Loans,
any other Commitments, and any Bid Loans of such Bank shall be provided by one
or more of the remaining Banks or a replacement bank acceptable to the Agent or,
upon payment of every such Loan and all related interest, fees, costs, and
expenses (including those payable under Section 5.6), the Commitments of such
Bank are permanently terminated; provided, further, the remaining Banks shall
have no obligation hereunder to increase their Commitments or provide any Bid
Loan of such Bank. Notwithstanding the foregoing, the Agent may only be replaced
subject to the requirements of Section 10.14 and provided that all Letters of
Credit shall have expired or been terminated or replaced.

Change of Lending Office.

                  Each Bank agrees that, upon the occurrence of any event giving
rise to increased costs or other special payments under Section 4.4.2 or 5.6.1
with respect to such Bank, it will, if requested by the Borrower, use reasonable
efforts (subject to overall policy considerations of such Bank) to designate
another lending office for any Loans or Letters of Credit affected by such
event, provided that such designation is made on such terms that such Bank and
its lending office suffer no economic, legal, or regulatory disadvantage, with
the objective of avoiding the consequence of the event giving rise to the
operation of such Sections. Nothing in this Section 5.4.3 shall affect or
postpone any of the Obligations of the Borrower or any other Loan Party or the
rights of the Agent or any Bank provided in this Agreement.

Reduction of Commitment.

                  The Borrower shall have the right at any time and from time to
time upon five (5) Business Days' prior written notice to Agent to permanently
and ratably reduce, in whole multiples of $2,500,000 of principal, or terminate
the Commitments without penalty or premium, except as hereinafter set forth,
provided that the Revolving Credit Commitments and the Convertible Revolving
Credit Commitments shall be reduced by equal amounts and any such reduction or
termination shall be accompanied by (a) the payment in full of any Commitment
Fee and other fees then accrued on the amount of such reduction or termination
(b) prepayment of the Revolving Credit Notes and the Convertible Revolving
Credit Notes (and, if necessary, of the Swingline Note and any Bid Note(s),
together with cash collateralization, if necessary, of the Letters of Credit),
together with the full amount of interest accrued on the principal sum to be
prepaid (and all amounts referred to in Section 5.6 hereof),



                                      -44-
<PAGE>   57


to the extent that the aggregate amount thereof then outstanding exceeds the
Commitments as so reduced or terminated. From the effective date of any such
reduction or termination, the obligations of Borrower to pay the Commitment Fee
shall correspondingly be reduced or cease, as the case may be.

(Reserved).

Additional Compensation in Certain Circumstances.

Increased Costs or Reduced Return Resulting From Taxes, Reserves, Capital
     Adequacy Requirements, Expenses, Etc.

                  If, after the Closing Date, any Law, guideline, or
interpretation or any change in any Law, guideline, or interpretation or
application thereof by any Official Body charged with the interpretation or
administration thereof or compliance with any request or directive (whether or
not having the force of Law) of any central bank or other Official Body:

                  (i) subjects any Bank to any tax or changes the basis of
taxation with respect to this Agreement, the Committed Loans or the Bid Loans or
payments by the Borrower of principal, interest, fees, or other amounts due from
the Borrower hereunder (except for taxes on the overall net income of such
Bank),

                  (ii) imposes, modifies, or deems applicable any reserve,
special deposit, or similar requirement against credits or commitments to extend
credit extended by, or assets (funded or contingent) of, deposits with or for
the account of, or other acquisitions of funds by, any Bank, or

                  (iii) imposes, modifies, or deems applicable any capital
adequacy or similar requirement (A) against assets (funded or contingent) of, or
letters of credit, other credits, or commitments to extend credit extended by,
any Bank, or (B) otherwise applicable to the obligations of any Bank under this
Agreement,

                  (iv) and the result of any of the foregoing is to increase the
cost to, reduce the income receivable by, or impose any expense (including loss
of margin) upon any Bank with respect to this Agreement, or the making,
maintenance, or funding of any part of the Committed Loans or the Bid Loans (or,
in the case of any capital adequacy or similar requirement, to have the effect
of reducing the rate of return on any Bank's or its holding company's capital,
taking into consideration such Bank's or holding company's customary policies
with respect to capital adequacy) by an amount which such Bank in its sole
discretion deems to be material, such Bank shall from time to time notify the
Borrower and the Agent of the amount determined in good faith (using any
averaging and attribution methods employed in good faith) by such Bank to be
necessary to compensate such Bank for such increase in cost, reduction of
income, additional expense, or reduced rate of return. Such notice shall set
forth in reasonable detail the calculation determining the basis for such
determination. Such amount shall be due and payable by the Borrower to such Bank
twenty (20) Business Days after such notice is given.

Indemnity.

                  In addition to the compensation required by Section 5.6.1
[Increased Costs, Etc.], the Borrower shall indemnify each Bank against all
liabilities, losses, or expenses (including loss of margin, any loss or expense
incurred in liquidating or employing deposits from third parties, and any loss
or



                                      -45-
<PAGE>   58


expense incurred in connection with funds acquired by a Bank to fund or maintain
Loans subject to a Euro-Rate Option or the Bid Loan Fixed Rate Option) which
such Bank sustains or incurs as a consequence of any:

                  (i) payment, prepayment, conversion, or renewal of any Loan to
which a Euro-Rate Option or the Bid Loan Fixed Rate Option applies on a day
other than the last day of the corresponding Interest Period (whether or not
such payment or prepayment is mandatory, voluntary, or automatic and whether or
not such payment or prepayment is then due), or

                  (ii) attempt by the Borrower to revoke (expressly, by later
inconsistent notices, or otherwise) in whole or part any Loan Requests or notice
relating to prepayments, or

                  (iii) default by the Borrower in the performance or observance
of any covenant or condition contained in this Agreement or any other Loan
Document, including any failure of the Borrower to pay when due (by acceleration
or otherwise) any principal of or interest on the Committed Loans or the Bid
Loans, any fee, or any other amount due hereunder, or

                  (iv) payment or prepayment of any Bid Loan on a day other than
the maturity date thereof (whether or not such payment or prepayment is
mandatory or voluntary).

                  (v) If any Bank sustains or incurs any such loss or expense,
it shall from time to time notify the Borrower of the amount determined in good
faith by such Bank (which determination may include such assumptions,
allocations of costs and expenses, and averaging or attribution methods as such
Bank shall deem reasonable) to be necessary to indemnify such Bank for such loss
or expense. Such notice shall set forth in reasonable detail the calculation
determining the basis for such determination. Such amount shall be due and
payable by the Borrower to such Bank twenty (20) Business Days after such notice
is given.

                  For all purposes of this Agreement, each Bank's and Agent's
determination of amounts payable under, and actions required or authorized by,
Section 4.4 or Section 5.6 shall be calculated, at each Bank's and Agent's
option, as though each Bank and Agent funded its Loans under the Euro-Rate
Option through the purchase of deposits of the types and maturities
corresponding to the deposits used as a reference in determining the Euro-Rate
applicable to such Loans, whether in fact that is or is not the case.

                  Borrower and the other Loan Parties acknowledge and agree that
payment of any indemnity under this Section 5.6 does not excuse any Obligation
arising under any related or unrelated Hedge Agreement.

Taxes.

No Deductions.

                  All payments made by Borrower hereunder and under each Note
shall be made free and clear of and without deduction for any present or future
taxes, levies, imposts, deductions, charges, or withholdings, and all
liabilities with respect thereto, excluding taxes imposed on the net income of
any Bank and all income and franchise taxes applicable to any Bank of the United
States (all such nonexcluded taxes, levies, imposts, deductions, charges,
withholdings, and liabilities being hereinafter



                                      -46-
<PAGE>   59


referred to as "Taxes"). If Borrower shall be required by Law to deduct any
Taxes from or in respect of any sum payable hereunder or under any Note, (i) the
sum payable shall be increased as may be necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 5.7.1) each Bank receives an amount equal to the sum it would
have received had no such deductions been made, (ii) Borrower shall make such
deductions and (iii) Borrower shall timely pay the full amount deducted to the
relevant tax authority or other authority in accordance with applicable Law.

Stamp Taxes.

                  In addition, Borrower agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges, or
similar levies which arise from any payment made hereunder or from the
execution, delivery, or registration of, or otherwise with respect to, this
Agreement or any Note (hereinafter referred to as "Other Taxes").

Indemnification for Taxes Paid by a Bank.

                  Borrower shall indemnify each Bank for the full amount of
Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes
imposed by any jurisdiction on amounts payable under this Section 5.7.3) paid by
any Bank and any liability (including penalties, interest, and expenses) arising
therefrom or with respect thereto, whether or not such Taxes or Other Taxes were
correctly or legally asserted. The Agent shall use its best efforts, but shall
not be penalized for failure, to alert Borrower to the assertion of any such
claim for taxes. This indemnification shall be made within 30 days from the date
a Bank makes written demand therefor.

Certificate.

                  Within 30 days after the date of any payment of any Taxes by
Borrower, Borrower shall furnish to each Bank, at its address referred to
herein, the original or a certified copy of a receipt evidencing payment
thereof. If no Taxes are payable in respect of any payment by Borrower, such
Borrower shall, if so requested by a Bank, provide a certificate of an officer
of Borrower to that effect.

Survival.

                  Without prejudice to the survival of any other agreement of
Borrower hereunder, the agreements and obligations of Borrower contained in
Sections 5.7.1 through 5.7.5 shall survive the payment in full of principal and
interest hereunder and under any instrument delivered hereunder.

Judgment Currency.

Currency Conversion Procedures for Judgments.

                  If for the purposes of obtaining judgment in any court it is
necessary to convert a sum due hereunder or under a Note in any currency (the
"Original Currency") into another currency (the "Other Currency"), the parties
hereby agree, to the fullest extent permitted by Law, that the rate of exchange
used shall be that at which in accordance with normal banking procedures each
Bank could purchase the Original Currency with the Other Currency after any
premium and costs of exchange on the Business Day preceding that on which final
judgment is given.



                                      -47-
<PAGE>   60


Indemnity in Certain Events.

                  The obligation of Borrower in respect of any sum due from
Borrower to any Bank hereunder shall, notwithstanding any judgment in an Other
Currency, whether pursuant to a judgment or otherwise, be discharged only to the
extent that, on the Business Day following receipt by any Bank of any sum
adjudged to be so due in such Other Currency, such Bank may in accordance with
normal banking procedures purchase the Original Currency with such Other
Currency. If the amount of the Original Currency so purchased is less than the
sum originally due to such Bank in the Original Currency, Borrower agrees, as a
separate obligation and notwithstanding any such judgment or payment, to
indemnify such Bank against such loss.

Notes.

                  Upon the request of any Bank, the Revolving Credit Loans or
Convertible Revolving Credit Loans made by such Bank may be evidenced
respectively by a Revolving Credit Note or Convertible Revolving Credit Note, as
the case may be, in the form of Exhibit 1.1(R) or Exhibit 1.1(C).

REPRESENTATIONS AND WARRANTIES

Representations and Warranties.

                  The Loan Parties, jointly and severally, represent and warrant
to the Agent and each of the Banks as follows:

Organization and Qualification; Merger.

                  Each of Borrower and its Subsidiaries is a corporation,
partnership, limited liability company, or other entity duly organized, validly
existing, and in good standing under the laws of its jurisdiction of
organization. Each of Borrower and its Subsidiaries has the lawful power to own
or lease its properties and to engage in the business it presently conducts or
proposes to conduct, except where the failure to have such power would not, in
the aggregate, result in a Material Adverse Change. Each of Borrower and its
Subsidiaries is duly licensed or qualified and in good standing in each
jurisdiction where the property owned or leased by it or the nature of the
business transacted by it or both makes such licensing or qualification
necessary, except where the failure to be so licensed or qualified or in good
standing would not, in the aggregate, result in a Material Adverse Change. The
Merger has been consummated in accordance with the terms of the Merger Agreement
and applicable Law and Borrower is the resulting corporation from the merger of
WABCO and MotivePower pursuant to the Merger Agreement.

Subsidiaries.

                  (a) Schedule 6.1.2 states the name of each of the Borrower's
Subsidiaries, its jurisdictions of incorporation (or organization) and
qualification, its authorized capital stock or other ownership interests, the
issued and outstanding shares or similar interests (referred to herein as the
"Subsidiary Shares"), and the owners thereof. The Borrower has good and
marketable title to all of the Subsidiary Shares it purports to own, free and
clear in each case of any Lien, except for Permitted Liens. All Subsidiary
Shares have been validly issued, and all Subsidiary Shares are fully paid and




                                      -48-
<PAGE>   61


nonassessable. There are no options, warrants, or other rights outstanding to
purchase any such Subsidiary Shares, except as indicated on Schedule 6.1.2.

                  (b) There is no direct or indirect Subsidiary of Borrower
which is not a Loan Party hereunder, other than direct or indirect Subsidiaries
of the Loan Parties that are organized under the Laws of a country, or a
political subdivision of such country, other than the United States; and, each
such Subsidiary is in compliance with Section 8.2.10.

Power and Authority.

                  Each Loan Party has full power to enter into, execute,
deliver, and carry out this Agreement and the other Loan Documents to which it
is a party, to incur the Indebtedness contemplated by the Loan Documents and to
perform its Obligations under the Loan Documents to which it is a party, and all
such actions have been duly authorized by all necessary proceedings on its part.

Validity and Binding Effect.

                  This Agreement has been duly and validly executed and
delivered by each Loan Party, and each other Loan Document which any Loan Party
is required to execute and deliver on or after the date hereof will have been
duly executed and delivered by such Loan Party on the required date of delivery
of such Loan Document. This Agreement and each other Loan Document constitutes,
or will constitute, legal, valid, and binding obligations of each Loan Party
which is or will be a party thereto on and after its date of delivery thereof,
enforceable against such Loan Party in accordance with its terms, except to the
extent that enforceability of any of such Loan Document may be limited by
bankruptcy, insolvency, reorganization, moratorium, or other similar laws
affecting the enforceability of creditors' rights generally or limiting the
right of specific performance.

No Conflict.

                  Neither the execution and delivery of this Agreement or the
other Loan Documents by any Loan Party nor the consummation of the transactions
herein or therein contemplated or compliance with the terms and provisions
hereof or thereof by any of them, nor the applicability of this Agreement or any
other Loan Document to any non-domestic Subsidiary of Borrower, will conflict
with, constitute a default under, or result in any breach of (i) the terms and
conditions of the certificate of incorporation, bylaws, certificate of limited
partnership, partnership agreement, certificate of formation, limited liability
company agreement, or other organizational documents of Borrower or any
Subsidiary of Borrower or (ii) any Law or any material agreement, indenture, or
instrument or order, writ, judgment, injunction, or decree to which Borrower or
any Subsidiary of Borrower is a party or by which it is bound or to which it is
subject, or result in the creation or enforcement of any Lien, charge, or
encumbrance whatsoever upon any material property (now or hereafter acquired) of
Borrower or any Subsidiary of Borrower (other than Liens granted under the Loan
Documents).

Litigation.

                  Except as set forth on Schedule 6.1.6, there are no actions,
suits, proceedings, or investigations pending or, to the knowledge of any Loan
Party, threatened against Borrower or any Subsidiary of Borrower at law or
equity before any Official Body which individually or in the aggregate would be
reasonably likely to result in any Material Adverse Change. None of the Borrower
or any of its



                                      -49-
<PAGE>   62


Subsidiaries is in violation of any order, writ, injunction, or any decree of
any Official Body which would be reasonably likely to result in any Material
Adverse Change.

Title to Properties.

                  Each of Borrower and each of its Subsidiaries has good and
marketable title to or a valid leasehold interest in all material properties,
assets, and other rights which it purports to own or lease or which are
reflected as owned or leased on its books and records, free and clear of all
Liens and encumbrances except Permitted Liens, and subject to the terms and
conditions of the applicable leases. All leases of property are in full force
and effect without the necessity for any consent which has not previously been
obtained upon consummation of the transactions contemplated hereby, except where
the failure to obtain any such consent, individually or in the aggregate, would
not result in a Material Adverse Change.

Financial Statements.

                           (i) Historical Statements. MotivePower has delivered
to the Agent copies of its audited consolidated year-end financial statements
for and as of the end of the four (4) fiscal years ended December 31, 1995,
December 31, 1996, December 31, 1997, and December 31, 1998 and WABCO has
delivered to the Agent copies of its audited consolidated year-end financial
statements for and as of the end of the fiscal year ended December 31, 1998
(collectively, the "Annual Statements"). In addition, MotivePower and WABCO have
each delivered to the Agent copies of their respective unaudited consolidated
interim financial statements for the first three (3) fiscal quarters of fiscal
year 1999 through September 30, 1999 (the "Interim Statements") (the Annual and
Interim Statements being collectively referred to as the "Historical
Statements"). The Historical Statements were compiled from the books and records
maintained respectively by MotivePower's and WABCO's managements, and Borrower
represents and warrants that the Historical Statements are correct and complete
and, when combined, fairly represent the consolidated financial condition of the
Borrower and its Subsidiaries, subject to adjustment for costs of the Merger. In
addition, each of MotivePower and WABCO have delivered to the Agent financial
statements showing their consolidated and consolidating financial condition and
that of the other Loan Parties, as of the dates of the Historical Statements and
the results of operations for the fiscal periods then ended, and all of the
Historical Statements have been prepared in accordance with GAAP consistently
applied, subject (in the case of the Interim Statements) to normal year-end
audit adjustments.

                           (ii) Financial Projections. The Borrower has
delivered to the Agent two sets of financial projections of the Borrower and its
Subsidiaries taken as a whole for the period January 1, 1999, through December
31, 2004, derived from various assumptions of the Borrower's management,
including one set of projections based upon no acquisitions and another set
based upon the occurrence of acquisitions (the "Financial Projections"). On and
as of the Closing Date, the Financial Projections represent a reasonable range
of possible results in light of the history of the business, present and
foreseeable conditions, and the intentions of the Borrower's management, all
based upon the best information available to management on such date. On and as
of the Closing Date, the Financial Projections accurately reflect the
liabilities of the Borrower and its Subsidiaries upon consummation of the
transactions contemplated by Borrower as of the Closing Date.

                           (iii) Accuracy of Financial Statements. Neither the
Borrower nor any of its Subsidiaries has any material liabilities, contingent or
otherwise, or forward or long-term commitments



                                      -50-
<PAGE>   63


that are not disclosed in the Historical Statements or in the notes thereto, and
except as disclosed therein there are no unrealized or anticipated losses from
any commitments of the Borrower or any other Loan Party which may cause a
Material Adverse Change. Since December 31, 1998, no Material Adverse Change has
occurred with respect to MotivePower or WABCO.

Use of Proceeds; Margin Stock.

General. The Loan Parties intend to use the proceeds of the Loans in accordance
         with Sections 2.7 and 8.1.10.

Margin Stock. None of the Loan Parties or any Subsidiaries of any Loan Party
         engages or intends to engage principally, or as one of its important
         activities, in the business of extending credit for the purpose,
         immediately, incidentally, or ultimately, of purchasing or carrying
         margin stock (within the meaning of Regulation U). No part of the
         proceeds of any Loan has been or will be used, immediately,
         incidentally, or ultimately, to purchase or carry any margin stock or
         to extend credit to others for the purpose of purchasing or carrying
         any margin stock or to refund Indebtedness originally incurred for such
         purpose, or for any purpose which entails a violation of or which is
         inconsistent with the provisions of the regulations of the Board of
         Governors of the Federal Reserve System. None of the Borrower or any of
         its Subsidiaries holds or intends to hold margin stock in such amounts
         that more than 25% of the reasonable value of the assets of Borrower or
         any Subsidiary of Borrower are or will be represented by margin stock.

Full Disclosure.

                  Neither this Agreement nor any other Loan Document, nor any
certificate, statement, agreement, or other documents furnished to the Agent or
any Bank in connection herewith or therewith, contains any untrue or incomplete
statement of a material fact or omits to state a material fact necessary in
order to make the statements contained herein and therein, in light of the
circumstances under which they were made, not misleading; provided, however,
that to the extent any such information constitutes or incorporates a forecast
or projection, which shall remain subject however to Section 6.1.8(ii), the
Borrower represents that it acted in good faith and utilized assumptions
believed by it to be reasonable. There is no fact known to any Loan Party which
materially adversely affects the business, property, assets, financial
condition, results of operations, or prospects of Borrower or any Subsidiary of
Borrower which has not been set forth in this Agreement or in the certificates,
statements, agreements or other documents furnished in writing to the Agent and
the Banks prior to or at the date hereof in connection with the transactions
contemplated hereby.

Taxes.

                  Except as set forth on Schedule 6.1.11, all tax returns
required to have been filed with any Official Body with respect to each of
MotivePower and its Subsidiaries, WABCO and its Subsidiaries, and Borrower and
each of its Subsidiaries have been filed. Payment or adequate provision has been
made by Borrower for the payment of all taxes, fees, assessments, and other
governmental charges which have or may become due pursuant to said returns or to
assessments received, except to the extent that such taxes, fees, assessments,
and other charges are being contested in good faith by appropriate proceedings
diligently conducted and for which such reserves or other appropriate
provisions, if any, as shall be required by GAAP shall have been made. Except as
set forth on Schedule 6.1.11, there are no agreements or waivers extending the
statutory period of limitations applicable to any income tax return of Borrower
or any of its Subsidiaries for any period.



                                      -51-
<PAGE>   64


Consents and Approvals.

                  No consent, approval, exemption, order, or authorization of,
or a registration or filing with, any Official Body or any other Person is
required by any Law or any agreement in connection with the Merger or the
execution, delivery, and carrying out of this Agreement and the other Loan
Documents by any Loan Party, except as have been obtained or made on or prior to
the Closing Date, except as otherwise indicated on Schedule 6.1.12 or where the
failure to have been obtained on the Closing Date would not cause a Material
Adverse Change.

No Event of Default; Compliance With Instruments.

                  No event has occurred and is continuing and no condition
exists or will exist after giving effect to the borrowings or other extensions
of credit to be made on the Closing Date under or pursuant to the Loan Documents
which constitutes an Event of Default or Potential Default. None of the Borrower
or any of its Subsidiaries is in violation of (i) any term of its certificate of
incorporation, bylaws, certificate of limited partnership, partnership
agreement, certificate of formation, limited liability company agreement, or
other organizational documents or (ii) any material agreement, indenture, or
instrument to which it is a party or by which it or any of its properties may be
subject or bound where such violation would constitute a Material Adverse
Change.

Patents, Trademarks, Copyrights, Licenses, Etc.

                  Borrower and each of its Subsidiaries owns or possesses all
the material patents, trademarks, service marks, trade names, copyrights,
licenses, registrations, franchises, permits, and rights necessary to own and
operate its properties and to carry on its business as presently conducted and
planned to be conducted by Borrower or any such Subsidiary, without known,
possible, alleged, or actual conflict with the rights of others except where
such known, possible, alleged or actual conflicts would not, individually or in
the aggregate, result in a Material Adverse Change.

Insurance.

                  No notice has been given or claim made and no grounds exist to
cancel or avoid any Loan Party's insurance policies or surety or similar bonds
(or those of any predecessor of any Loan Party) or to reduce the coverage
provided thereby. Such policies and bonds provide adequate coverage from
insurers believed by the Borrower to be reputable and financially sound and such
policies and bonds are in amounts sufficient to insure the assets and risks of
each of Borrower and each of its Subsidiaries in accordance with prudent
business practice in its respective industry. Descriptions of insurance coverage
pertaining to Borrower and its Subsidiaries and their property is set forth on
Schedule 6.1.15.

Compliance With Laws.

                  Borrower and its Subsidiaries are in compliance in all
material respects with all applicable Laws (other than Environmental Laws which
are specifically addressed in Section 6.1.21) in all jurisdictions in which any
of them is presently or will be doing business except where the failure to do so
would not constitute a Material Adverse Change.



                                      -52-
<PAGE>   65


Material Contracts; Burdensome Restrictions.

                  All material contracts relating to the business operations of
Borrower or any of its Subsidiaries, including all employee benefit plans and
Labor Contracts, are described on Schedule 6.1.17 and are valid, binding, and
enforceable upon such Person and each of the other parties thereto in accordance
with their respective terms, and there is no default thereunder, to any Loan
Party's knowledge, with respect to parties other than such Loan Party. None of
the Borrower or any of its Subsidiaries is bound by any contractual obligation
or subject to any restriction in any organization document or any requirement of
Law, which would be reasonably likely to result in a Material Adverse Change.

Investment Companies; Regulated Entities.

                  None of the Borrower or any of its Subsidiaries is an
"investment company" registered or required to be registered under the
Investment Company Act of 1940 or under the "control" of an "investment company"
as such terms are defined in the Investment Company Act of 1940 and shall not
become such an "investment company" or under such "control." None of the
Borrower or any of its Subsidiaries is subject to any other Law limiting its
ability to incur Indebtedness for borrowed money.

Plans and Benefit Arrangements.

Group are in compliance in all material respects with any applicable provisions
of ERISA with respect to all Benefit Arrangements, Plans, and Multiemployer
Plans. There has been no Prohibited Transaction with respect to any Benefit
Arrangement or any Plan or, to the best knowledge of the Borrower, with respect
to any Multiemployer Plan or Multiple Employer Plan, which could result in any
material liability of the Borrower or any other member of the ERISA Group. The
Borrower, MotivePower, WABCO, and all other members of the ERISA Group have made
when due any and all payments required to be made under any agreement relating
to a Multiemployer Plan or a Multiple Employer Plan or any Law pertaining
thereto. With respect to each Plan and Multiemployer Plan, the Borrower,
MotivePower, WABCO, and each other member of the ERISA Group (i) have fulfilled
in all material respects their obligations under the minimum funding standards
of ERISA, (ii) have not incurred any liability to the PBGC, and (iii) have not
had asserted against them any penalty for failure to fulfill the minimum funding
requirements of ERISA. All Plans, Benefit Arrangements, and Multiemployer Plans
have been administered in accordance with their terms and applicable Law.

                           (ii) No event requiring notice to the PBGC under
Section 302(f)(4)(A) of ERISA has occurred or is reasonably expected to occur
with respect to any Plan, and no amendment with respect to which security is
required under Section 307 of ERISA has been made or is reasonably expected to
be made to any Plan.

                           (iii) Neither the Borrower, MotivePower, WABCO, nor
any other member of the ERISA Group has incurred and the Borrower reasonably
expects not to incur any material withdrawal liability under ERISA to any
Multiemployer Plan or Multiple Employer Plan. Neither the Borrower, MotivePower,
WABCO, nor any other member of the ERISA Group has been notified by any
Multiemployer Plan or Multiple Employer Plan that such Multiemployer Plan or
Multiple Employer Plan has been terminated within the meaning of Title IV of
ERISA and, to the best knowledge of the Borrower, no Multiemployer Plan or
Multiple Employer Plan is reasonably expected to be reorganized or terminated,
within the meaning of Title IV of ERISA.

Employment Matters.

                  Each of the Borrower and its Subsidiaries is (and each of
MotivePower and WABCO were) in compliance with the Labor Contracts and all
applicable federal, state, and local labor and employment Laws including those
related to equal employment opportunity and affirmative action, labor relations,
minimum wage, overtime, child labor, medical insurance continuation, worker
adjustment and relocation notices, immigration controls, and worker and
unemployment compensation, except in all cases where the failure to comply would
not constitute a Material Adverse Change. There are no outstanding grievances,
arbitration awards, or appeals therefrom arising out of the Labor Contracts or
current or threatened strikes, picketing, handbilling, or other work stoppages
or slowdowns at facilities of Borrower or any of its Subsidiaries which in any
case would constitute a Material Adverse Change.

Environmental Matters.

                  Except as set forth in Schedule 6.1.21, none of the Borrower
or any of its Subsidiaries (or MotivePower or WABCO) has received any
Environmental Complaint from any Official Body or private Person alleging that
Borrower or any such Subsidiary (or MotivePower or WABCO) or any prior or
subsequent owner of any of the Property is a potentially responsible party under
the Comprehensive Environmental Response, Cleanup and Liability Act, 42 U.S.C.
section 9601, et seq., or any other Law and none of Borrower or any of its
Subsidiaries has any reason to believe that such an Environmental Complaint is
reasonably likely to be received. There are no pending or, to any Loan Party's
knowledge, threatened Environmental Complaints relating to Borrower or any of
its Subsidiaries or, to any Loan Party's knowledge, any prior or subsequent
owner of any of the Property pertaining to, or arising out of, any Environmental
Conditions.

Senior Debt Status.

                  The Obligations of each Loan Party under this Agreement, the
Guaranty Agreement, and each of the other Loan Documents to which it is a party
do rank and will continue to rank senior to or at least pari passu in priority
of payment with all other Indebtedness of such Loan Party except Indebtedness of
such Loan Party to the extent secured by Permitted Liens. There is no Lien upon

existence as a corporation, limited partnership, limited liability company, or

                                      -57-
<PAGE>   70


Payment of Liabilities, Including Taxes, Etc.

                  Each of Borrower and its Subsidiaries shall duly pay and
discharge all liabilities to which it is subject or which are asserted against
it, promptly as and when the same shall become due and payable, including all
taxes, assessments, and governmental charges upon it or any of its properties,
assets, income, or profits, prior to the date on which penalties attach thereto,
except to the extent that such liabilities, including taxes, assessments, or
charges are being contested in good faith and by appropriate and lawful
proceedings diligently conducted and for which such reserve or other appropriate
provisions, if any, as shall be required by GAAP shall have been made, but only
to the extent that failure to discharge any such liabilities would result in a
Material Adverse Change, provided that the Borrower and each of its Subsidiaries
will pay all such liabilities forthwith upon the commencement of proceedings to
foreclose any Lien which may have attached as security therefor.

Maintenance of Insurance.

                  Each of Borrower and its Subsidiaries shall insure its
properties and assets against loss or damage by fire and such other insurable
hazards as such assets are commonly insured (including fire, extended coverage,
property damage, workers' compensation, public liability, and business
interruption insurance) and against other risks (including errors and omissions)
in such amounts as similar properties and assets are insured by prudent
companies in similar circumstances carrying on similar businesses, and with
insurers believed by the Borrower to be reputable and financially sound,
including self-insurance to the extent customary, all as reasonably determined
by the Agent. Borrower shall provide to the Agent and each of the Banks, no
later than the date on which annual financial statements are to be provided to
the Agent and the Banks pursuant to Section 8.3.2, evidence (in such form as is
satisfactory to the Agent) of compliance with the terms of this Section.

Maintenance of Properties and Leases.

                  Each of Borrower and its Subsidiaries shall maintain in good
repair, working order, and condition (ordinary wear and tear excepted) in
accordance with the general practice of other businesses of similar character
and size, all of those properties useful or necessary to its business, and from
time to time each of Borrower and its Subsidiaries will make or cause to be made
all appropriate repairs, renewals, or replacements thereof.

Maintenance of Patents, Trademarks, Etc.

                  Each of Borrower and its Subsidiaries shall maintain in full
force and effect all patents, trademarks, service marks, trade names,
copyrights, licenses, franchises, permits, and other authorizations necessary
for the ownership and operation of its properties and business if the failure so
to maintain the same would constitute a Material Adverse Change.

Visitation Rights.

                  Each of Borrower and its Subsidiaries shall permit any of the
officers or authorized employees or representatives of the Agent or any of the
Banks to visit and inspect any of its properties and to examine and make
excerpts from its books and records and discuss its business affairs, finances,
and accounts with its officers, all in such detail and at such times and as
often as any of the Banks or Agent may reasonably request, provided that each
Bank shall provide the Borrower and the Agent with reasonable notice prior to
any visit or inspection. In the event any Bank desires to conduct an audit of


                                      -58-
<PAGE>   71


Borrower or any of its Subsidiaries, such Bank shall make a reasonable effort to
conduct such audit contemporaneously with any audit to be performed by the
Agent.

Keeping of Records and Books of Account.

                  Each Loan Party shall, and shall cause each Subsidiary of any
Loan Party to, maintain and keep proper books of record and account which enable
the Borrower and its Subsidiaries to issue financial statements in accordance
with GAAP and as otherwise required by applicable Laws of any Official Body
having jurisdiction over the Borrower, and in which full, true, and correct
entries shall be made in all material respects of all its dealings and business
and financial affairs.

Plans and Benefit Arrangements.

                  The Borrower shall, and shall cause each other member of the
ERISA Group to, comply with ERISA, the Internal Revenue Code and other
applicable Laws applicable to Plans and Benefit Arrangements except where such
failure, alone or in conjunction with any other failure, would not result in a
Material Adverse Change. Without limiting the generality of the foregoing, the
Borrower shall cause all of its Plans and all Plans maintained by any member of
the ERISA Group to be funded in accordance with the minimum funding requirements
of ERISA and shall make, and cause each member of the ERISA Group to make, in a
timely manner, all contributions due to Plans, Benefit Arrangements, and
Multiemployer Plans.

Compliance With Laws.

                  Each of Borrower and its Subsidiaries shall comply with all
applicable Laws, including all Environmental Laws and all Laws regarding labor
and employment, health, safety and employment benefits, in all respects,
provided that it shall not be deemed to be a violation of this Section 8.1.9 if
any failure to comply with any Law would not result in fines, penalties,
remediation costs, other similar liabilities, or injunctive relief which in the
aggregate would constitute a Material Adverse Change.

Use of Proceeds.

                  The Letters of Credit and the proceeds of the Loans may be
used by Borrower only to refinance the amounts outstanding under the Pulse Note,
the MotivePower Credit Agreement and the WABCO Credit Agreement and for general
corporate purposes, Permitted Acquisitions and working capital needs of the
Borrower and its Subsidiaries to the extent not in violation hereof. The Letters
of Credit and the proceeds of the Loans may not be used for any purpose which
contravenes any applicable Law or any provision hereof.

Year 2000.

                  The Borrower and its Subsidiaries have reviewed areas within
their business and operations which could be materially adversely affected by,
and have developed or are developing a program to address on a timely basis, the
risk that material computer applications used by the Borrower or its
Subsidiaries (or any of their respective material suppliers, customers or
vendors) may be unable to recognize and perform properly date-sensitive
functions involving dates prior to and after December 31, 1999 ( the "Year 2000
Problem"). To the best of Borrower's knowledge, the Year 2000 Problem will not
result in any Material Adverse Change.

benefit of the Banks a Lien of equal priority covering the same Property as is

Subsidiaries arising from industrial development bond or similar financing,

to whom any Obligation is owed by any Loan Party hereunder or under any other
Loan Document or any participant of such Bank which has agreed in writing to be
bound by the provisions of Section 10.13 and any branch, Subsidiary, or
Affiliate of such Bank or participant anywhere in the world shall have the
right, in addition to all other rights and remedies available to it, without
notice to such Loan Party, to set-off against and apply to the then unpaid
balance of all the Loans and all other Obligations of the Borrower and the other

general or special, provisionally credited or finally credited, or otherwise)
now or hereafter maintained by the Borrower or such other Loan Party for its own
account (but not including funds held in custodian or trust accounts) with such
Bank or participant or such branch, Subsidiary, or Affiliate. Such right shall
exist whether or not any Bank or the Agent shall have made any demand under this
Agreement or any other Loan Document, whether or not such debt owing to or funds
held for the account of the Borrower or such other Loan Party is or are matured
or unmatured and regardless of the existence or adequacy of any Guaranty or any
other security, right or remedy available to any Bank or the Agent; and

Suits, Actions, Proceedings.

                  If an Event of Default shall occur and be continuing, and
whether or not the Agent shall have accelerated the maturity of Committed Loans
pursuant to any of the foregoing provisions of this Section 9.2, the Agent or
any Bank, if owed any amount with respect to the Loans, may proceed to protect
and enforce its rights by suit in equity, action at law and/or other appropriate
proceeding, whether for the specific performance of any covenant or agreement
contained in this Agreement or the other Loan Documents (other than a Hedge
Agreement), including as permitted by applicable Law the obtaining of the ex
parte appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, proceed to enforce the payment thereof or any other
legal or equitable right of the Agent or such Bank; and

Application of Proceeds.

                  From and after the date on which the Agent has taken any
action pursuant to this Section 9.2 and until all Obligations of the Loan
Parties have been paid in full, any and all proceeds received by the Agent from
the exercise of any remedy by the Agent, shall be applied as follows:

                           (i) first, to reimburse the Agent and the Banks for

attorneys' and paralegals' fees and legal expenses, incurred by the Agent or the
Banks in connection with collection of any Obligations of any of the Loan
Parties under any of the Loan Documents;

                           (ii) second, to the repayment of all Indebtedness
then due and unpaid of the Loan Parties to the Banks incurred under this
Agreement or any of the other Loan Documents, whether of principal, interest,
fees, expenses, or otherwise, in such manner as the Agent may determine in its
discretion;

                           (iii) third, to fund any cash collateral account with
respect to Letters of Credit as provided for herein; and

                           (iv) the balance, if any, as required by Law.

Other Rights and Remedies.

                  In addition to all of the rights and remedies contained in
this Agreement or in any of the other Loan Documents, the Agent shall have all
of the rights and remedies under applicable Law, all of which rights and
remedies shall be cumulative and nonexclusive, to the extent permitted by Law.
The Agent may, and upon the request of the Required Banks shall, exercise all
post-default rights granted to the Agent and the Banks under the Loan Documents
(other than a Hedge Agreement) or applicable law.

Right of Competitive Bid Loan Banks.

         If any Event of Default shall occur and be continuing, the Banks which
have any Bid Loans then outstanding to the Borrower (the "Bid Loan Banks") shall
not be entitled to accelerate payment of the Bid Loans or to exercise any right
or remedy related to the collection of the Bid Loans until the Commitments shall
be terminated hereunder pursuant to Section 9.2. Upon such a termination of the
Commitments: (i) references to Revolving Credit Loans in Section 9.2 shall be
deemed to apply also to the Bid Loans and the Bid Loan Banks shall be entitled
to all enforcement rights given to a holder of a Revolving Credit Loan in
Section 9.2, and (ii) the definition of Required Banks shall be changed as
provided in Section 1.1



                                      -76-

so that each Bank shall have voting rights hereunder in proportion to its share
of the total Loans outstanding.

THE AGENT

Appointment.

         Each Bank hereby irrevocably designates, appoints, and authorizes ABN
AMRO to act as Agent for such Bank under this Agreement and to execute and
deliver or accept on behalf of each of the Banks the other Loan Documents (other
than any Hedge Agreement). Each Bank hereby irrevocably authorizes the Agent to
take such action on its behalf under the provisions of this Agreement and the
other Loan Documents (other than any Hedge Agreement) and any other instruments
and agreements referred to herein, and to exercise such powers and to perform
such duties hereunder as are specifically delegated to or required of the Agent
by the terms hereof, together with such powers as are reasonably incidental
thereto. ABN AMRO Bank N.V. agrees to act as the Agent on behalf of the Banks to
the extent provided in this Agreement.

Delegation of Duties.

         The Agent may perform any of its duties hereunder by or through agents
or employees (provided such delegation does not constitute a relinquishment of
its duties as Agent) and, subject to Sections 10.5 and 10.6, shall be entitled
to engage and pay for the advice or services of any attorneys, accountants, or
other experts concerning all matters pertaining to its duties hereunder and to
rely upon any advice so obtained.

Nature of Duties; Independent Credit Investigation.
- --------------------------------------------------

         The Agent shall have no duties or responsibilities except those
expressly set forth in this Agreement and no implied covenants, functions,
responsibilities, duties, obligations, or liabilities shall be read into this
Agreement or otherwise exist. The duties of the Agent shall be mechanical and
administrative in nature; the Agent shall not have by reason of this Agreement a
fiduciary or trust relationship in respect of any Bank; and nothing in this
Agreement, express or implied, is intended to or shall be so construed as to
impose upon the Agent any obligations in respect of this Agreement except as
expressly set forth herein. Without limiting the generality of the foregoing,
the use of the term "agent" in this Agreement with reference to the Agent is not
intended to connote any fiduciary or other implied (or express) obligations
arising under agency doctrine of any applicable Law. Instead, such term is used
merely as a matter of market custom, and is intended to create or reflect only
an administrative relationship between independent contracting parties. Each
Bank expressly acknowledges (i) that the Agent has not made any representations
or warranties to it and that no act by the Agent hereafter taken, including any
review of the affairs of any of the Loan Parties, shall be deemed to constitute
any representation or warranty by the Agent to any Bank; (ii) that it has made
and will continue to make, without reliance upon the Agent, its own independent
investigation of the financial condition and affairs and its own appraisal of
the creditworthiness of each of the Loan Parties in connection with this
Agreement and the making and continuance of the Loans hereunder; and (iii)
except as expressly provided herein, that the Agent shall have no duty or
responsibility, either initially or on a continuing basis, to provide any Bank
with any credit or other information with respect thereto, whether coming into
its possession before the making of any Loan or at any time or times thereafter.

         The Agent agrees, upon the written request of the Required Banks, to
take or refrain from taking any action of the type specified as being within the
Agent's rights, powers, or discretion herein, provided that the Agent shall not
be required to take any action which exposes the Agent to personal liability or
which is contrary to this Agreement or any other Loan Document or applicable
Law. In the absence of a request by the Required Banks, the Agent shall have
authority, in its sole discretion, to take or not to take any such action,
unless this Agreement specifically requires the consent of the Required Banks or
all of the Banks. Any action taken or failure to act pursuant to such
instructions or discretion shall be binding on the Banks, subject to Section
10.6. Subject to the provisions of Section 10.6, no Bank shall have any right of
action whatsoever against the Agent as a result of the Agent acting or
refraining from acting hereunder in accordance with the instructions of the
Required Banks, or in the absence of such instructions, in the absolute
discretion of the Agent.

Reimbursement and Indemnification of Agent by the Borrower.

         The Borrower unconditionally agrees to pay or reimburse the Agent and
hold the Agent harmless against (a) liability for the payment of all reasonable
out-of-pocket costs, expenses, and disbursements, including fees and expenses of
counsel (including the allocated costs of staff counsel), appraisers, and
environmental consultants, incurred by the Agent (i) in connection with the
development, negotiation, preparation, printing, execution, administration,
syndication, interpretation, and performance of this Agreement and the other
Loan Documents, (ii) relating to any requested amendments, waivers, or consents
pursuant to the provisions hereof, (iii) in connection with the enforcement of
this Agreement or any other Loan Document or collection of amounts due hereunder
or thereunder or the proof and allowability of any claim arising under this
Agreement or any other Loan Document, whether in bankruptcy or receivership
proceedings or otherwise, and (iv) in any workout or restructuring or in
connection with the protection, preservation, exercise, or enforcement of any of
the terms hereof or of any rights hereunder or under any other Loan Document or
in connection with any foreclosure, collection, or bankruptcy proceedings, and
(b) all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses, or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by, or asserted against the Agent,
in its capacity as such, in any way relating to or arising out of this Agreement
or any other Loan Documents or any action taken or omitted by the Agent
hereunder or thereunder, provided that the Borrower shall not be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses, or disbursements if the same results from the
Agent's gross negligence or willful misconduct, or if the Borrower was not given
notice of the subject claim and the opportunity to participate in the defense
thereof, at its expense (except that the Borrower shall remain liable to the
extent such failure to give notice does not result in a loss to the Borrower),
or if the same results from a compromise or settlement agreement entered into
without the consent of the Borrower, which shall not be unreasonably withheld.

Exculpatory Provisions; Limitation of Liability.

         Neither the Agent nor any of its directors, officers, employees,
agents, attorneys, or Affiliates shall (a) be liable to any Bank for any action
taken or omitted to be taken by it or them hereunder, or in connection herewith
including pursuant to any Loan Document, unless caused by its or their own gross
negligence or willful misconduct, (b) be responsible in any manner to any of the
Banks for the effectiveness, enforceability, genuineness, validity, or the due
execution of this Agreement or any other Loan Documents or for any recital,
representation, warranty, document, certificate, report, or statement



                                      -78-

herein or made or furnished under or in connection with this Agreement or any
other Loan Documents, or (c) be under any obligation to any of the Banks to
ascertain or to inquire as to the performance or observance of any of the terms,
covenants, or conditions hereof or thereof on the part of the Loan Parties, or
the financial condition of the Loan Parties, or the existence or possible
existence of any Event of Default or Potential Default. No claim may be made by
any of the Loan Parties, any Bank, the Agent, or any of their respective
Subsidiaries against the Agent, any Bank, or any of their respective directors,
officers, employees, agents, attorneys, or Affiliates, or any of them, for any
special, indirect, or consequential damages or, to the fullest extent permitted
by Law, for any punitive damages in respect of any claim or cause of action
(whether based on contract, tort, statutory liability, or any other ground)
based on, arising out of, or related to any Loan Document or the transactions
contemplated hereby or any act, omission, or event occurring in connection
therewith, including the negotiation, documentation, administration, or
collection of the Loans, and each of the Loan Parties (for itself and on behalf
of each of its Subsidiaries), the Agent and each Bank hereby waive, release and
agree never to sue upon any claim for any such damages, whether such claim now
exists or hereafter arises and whether or not it is now known or suspected to
exist in its favor. Each Bank agrees that, except for notices, reports, and
other documents expressly required to be furnished to the Banks by the Agent
hereunder or given to the Agent for the account of or with copies for the Banks,
the Agent and each of its directors, officers, employees, agents, attorneys or
Affiliates shall not have any duty or responsibility to provide any Bank with
any credit or other information concerning the business, operations, property,
condition (financial or otherwise), prospects, or creditworthiness of the Loan
Parties which may come into the possession of the Agent or any of its directors,
officers, employees, agents, attorneys, or Affiliates.

Reimbursement and Indemnification of Agent by Banks.

         Each Bank agrees to reimburse and indemnify the Agent (to the extent
not reimbursed by the Borrower and without limiting the Obligation of the
Borrower to do so) in proportion to its Ratable Share from and against all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses, or disbursements, including attorneys' fees and disbursements
(including the allocated costs of staff counsel), and costs of appraisers and
environmental consultants, of any kind or nature whatsoever which may be imposed
on, incurred by, or asserted against the Agent, in its capacity as such, in any
way relating to or arising out of this Agreement or any other Loan Documents or
any action taken or omitted by the Agent hereunder or thereunder, provided that
no Bank shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses, or
disbursements (a) if the same results from the Agent's gross negligence or
willful misconduct, or (b) if such Bank was not given notice of the subject
claim and the opportunity to participate in the defense thereof, at its expense
(except that such Bank shall remain liable to the extent such failure to give
notice does not result in a loss to the Bank), or (c) if the same results from a
compromise and settlement agreement entered into without the consent of such
Bank, which shall not be unreasonably withheld. In addition, each Bank agrees
promptly upon demand to reimburse the Agent (to the extent not reimbursed by the
Borrower and without limiting the Obligation of the Borrower to do so) in
proportion to its Ratable Share for all amounts due and payable by the Borrower
to the Agent in connection with the Agent's periodic audit of the Loan Parties'
books, records, and business properties.

Reliance by Agent.

         The Agent shall be entitled to rely upon any writing, telegram, telex,
or teletype message, resolution, notice, consent, certificate, letter,
cablegram, statement, order, or other document or



                                      -79-
<PAGE>   92


conversation by telephone or otherwise believed by it to be genuine and correct
and to have been signed, sent, or made by the proper Person or Persons, and upon
the advice and opinions of counsel and other professional advisers selected by
the Agent. The Agent shall be fully justified in failing or refusing to take any
action hereunder unless it shall first be indemnified to its satisfaction by the
Banks against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action.

Notice of Default.

         The Agent shall not be deemed to have knowledge or notice of the
occurrence of any Potential Default or Event of Default unless the Agent has
received written notice from a Bank or the Borrower referring to this Agreement,
describing such Potential Default or Event of Default and stating that such
notice is a "notice of default."

Notices.

         The Agent shall promptly send to each Bank a copy of all notices
received from the Borrower pursuant to the provisions of this Agreement or the
other Loan Documents (other than a Hedge Agreement) promptly upon receipt
thereof. The Agent shall promptly notify the Borrower and the other Banks of
each change in the Base Rate and the effective date thereof.

Banks in Their Individual Capacities.

         With respect to its Revolving Credit Commitment, the Revolving Credit
Loans, the Convertible Revolving Credit Loan Commitment, and the Convertible
Revolving Credit Loan and any Bid Loans made by it and any other rights and
powers given to it as a Bank hereunder or under any of the other Loan Documents,
the Agent shall have the same rights and powers hereunder as any other Bank and
may exercise the same as though it were not the Agent, and the term "Banks"
shall, unless the context otherwise indicates, include the Agent in its
individual capacity. ABN AMRO Bank and its Affiliates and each of the Banks and
their respective Affiliates may, without liability to account, except as
prohibited herein, make loans to, accept deposits from, discount drafts for, act
as trustee under indentures of, and generally engage in any kind of banking or
trust business with, the Loan Parties and their Affiliates, in the case of the
Agent, as though it were not acting as Agent hereunder and in the case of each
Bank, as though such Bank were not a Bank hereunder. The Banks acknowledge that,
pursuant to such activities, the Agent or its Affiliates may (i) receive
information regarding the Loan Parties (including information that may be
subject to confidentiality obligations in favor of the Loan Parties) and
acknowledge that the Agent shall be under no obligation to provide such
information to them, and (ii) accept fees and other consideration from the Loan
Parties for services in connection with this Agreement and otherwise without
having to account for the same to the Banks.

Holders of Notes.

         The Agent may deem and treat any payee of any Note as the owner thereof
for all purposes hereof unless and until written notice of the assignment or
transfer thereof shall have been filed with the Agent. Any request, authority,
or consent of any Person who at the time of making such request or giving such
authority or consent is the holder of any Note shall be conclusive and binding
on any subsequent holder, transferee, or assignee of such Note or of any Note or
Notes issued in exchange therefor.



                                      -80-
<PAGE>   93


Equalization of Banks.

         The Banks and the holders of any participations in any Commitments or
Loans or other rights or obligations of a Bank hereunder agree among themselves
that, with respect to all amounts received by any Bank or any such holder for
application on any Obligation hereunder or under any such participation, whether
received by voluntary payment, by realization upon security, by the exercise of
the right of set-off or banker's lien, by counterclaim, or by any other non-pro
rata source, equitable adjustment will be made in the manner stated in the
following sentence so that, in effect, all such excess amounts will be shared
ratably among the Banks and such holders in proportion to their interests in
payments on the Loans, except as otherwise provided in Section 4.4.3, 5.4.2 or
5.6 or 5.7. The Banks or any such holder receiving any such amount shall
purchase for cash from each of the other Banks an interest in such Bank's Loans
in such amount as shall result in a ratable participation by the Banks and each
such holder in the aggregate unpaid amount of the Loans, provided that if all or
any portion of such excess amount is thereafter recovered from the Bank or the
holder making such purchase, such purchase shall be rescinded and the purchase
price restored to the extent of such recovery, together with interest or other
amounts, if any, required by law (including court order) to be paid by the Bank
or the holder making such purchase.

Successor Agent.

         The Agent (i) may resign as Agent or (ii) shall resign if such
resignation is requested by the Required Banks (if the Agent is a Bank, the
Agent's Loans and its Commitment shall be considered in determining whether the
Required Banks have requested such resignation) or required by Section 5.4.2, in
either case of (i) or (ii) by giving not less than thirty (30) days' prior
written notice to the Borrower. If the Agent shall resign under this Agreement,
then either (a) the Required Banks shall appoint from among the Banks a
successor agent for the Banks, subject to the consent of the Borrower, such
consent not to be unreasonably withheld, or (b) if a successor agent shall not
be so appointed and approved within the thirty (30) day period following the
Agent's notice to the Banks of its resignation, then the Agent shall appoint,
with the consent of the Borrower, such consent not to be unreasonably withheld,
a successor agent who shall serve as Agent until such time as the Required Banks
appoint and the Borrower consents to the appointment of a successor agent. Upon
its appointment pursuant to either clause (a) or (b) above, such successor agent
shall succeed to the rights, powers, and duties of the Agent, and the term
"Agent" shall mean such successor agent, effective upon its appointment, and the
former Agent's rights, powers, and duties as Agent shall be terminated without
any other or further act or deed on the part of such former Agent or any of the
parties to this Agreement. After the resignation of any Agent hereunder, the
provisions of this Section 10 shall inure to the benefit of such former Agent
and such former Agent shall not by reason of such resignation be deemed to be
released from liability for any actions taken or not taken by it while it was an
Agent under this Agreement.

Agent's Fee.

         The Borrower shall pay to the Agent a nonrefundable fee (the "Bid Loan
Processing Fee") in connection with processing Bid Loans, a nonrefundable fee
(the "Agent's Fee") for Agent's services hereunder, and such other fees and
expenses, pursuant to the terms of correspondence, dated as of November 9, 1999
(the "Agent's Letter"), between the Borrower and Agent, as amended from time to
time.

<PAGE>   94


Availability of Funds.

         The Agent may assume that each Bank has made or will make the proceeds
of a Loan available to the Agent unless the Agent shall have been notified by
such Bank on or before the later of (i) the close of Business on the Business
Day preceding the Borrowing Date with respect to such Loan, or (ii) two (2)
hours before the time on which the Agent actually funds the proceeds of such
Loan to the Borrower (whether using its own funds pursuant to this Section 10.16
or using proceeds deposited with the Agent by the Banks and whether such funding
occurs before or after the time on which Banks are required to deposit the
proceeds of such Loan with the Agent). The Agent may, in reliance upon such
assumption (but shall not be required to), make available to the Borrower a
corresponding amount. If such corresponding amount is not in fact made available
to the Agent by such Bank, the Agent shall be entitled to recover such amount on
demand from such Bank (or, if such Bank fails to pay such amount forthwith upon
such demand from the Borrower) together with interest thereon, in respect of
each day during the period commencing on the date such amount was made available
to the Borrower and ending on the date the Agent recovers such amount, at a rate
per annum equal to (i) the Federal Funds Effective Rate during the first three
(3) days after such interest shall begin to accrue and (ii) the applicable
interest rate in respect of such Loan after the end of such three-day period.

Calculations.

         In the absence of gross negligence or willful misconduct, the Agent
shall not be liable for any error in computing the amount payable to any Bank
whether in respect of the Loans, fees, or any other amounts due to the Banks
under this Agreement. In the event an error in computing any amount payable to
any Bank is made, the Agent, the Borrower and each affected Bank shall,
forthwith upon discovery of such error, make such adjustments as shall be
required to correct such error, and any compensation therefor will be calculated
at the Federal Funds Effective Rate.

Beneficiaries.

         Except as expressly provided herein, the provisions of this Section 10
are solely for the benefit of the Agent and the Banks, and the Loan Parties
shall not have any rights to rely on or enforce any of the provisions hereof. In
performing its functions and duties under this Agreement, the Agent shall act
solely as agent of the Banks and does not assume and shall not be deemed to have
assumed any obligation toward or relationship of agency or trust with or for any
of the Loan Parties.

MISCELLANEOUS

Modifications, Amendments, or Waivers.

         With the written consent of the Required Banks, the Agent, acting on
behalf of all the Banks, and the Borrower, on behalf of the Loan Parties, may
from time to time enter into written agreements amending or changing any
provision of this Agreement or any other Loan Document (other than a Hedge
Agreement) or the rights of the Banks or the Loan Parties hereunder or
thereunder, or may grant written waivers or consents to a departure from the due
performance of the Obligations (other than with respect to Obligations arising
out of a Hedge Agreement) of the Loan Parties hereunder or thereunder. Any such
agreement, waiver, or consent made with such written consent shall be effective
to bind all the Banks and the Loan Parties; provided, that, without the written
consent of all the Banks, no such agreement, waiver, or consent may be made
which will:



                                      -82-
<PAGE>   95


Increase of Commitment; Extension of Expiration Date.

                  Increase the amount of the Revolving Credit Commitment or
Convertible Revolving Credit Commitment, or Swingline Commitment of any Bank
hereunder or extend the Revolving Credit Expiration Date except pursuant to the
terms of Section 2.10.2 or the Convertible Revolving Credit Expiration Date,
except pursuant to the terms of Section 3.4 hereof;

Extension of Payment; Reduction of Principal, Interest or Fees; Modification of
     Terms of Payment.

                  Whether or not any Loans are outstanding, extend the time for
payment of principal or interest of any Loan, Reimbursement Obligation, Letter
of Credit Borrowings, any fee payable to any Bank, or reduce the principal
amount of or the rate of interest borne by any Loan or reduce the Commitment Fee
or any other fee payable to any Bank, or otherwise affect in a manner adverse to
any Bank, the terms of payment of the principal of or interest of any Loan, the
Commitment Fee or any other fee payable to any Bank;

Release of Guarantor or Security.

                  Release any Guarantor from its Obligations under the Guaranty
Agreement or any other material security for any of the Loan Parties'
Obligations; or

Miscellaneous.

                  Amend Section 5.2, 10.6 or 10.13 or this Section 11.1, alter
any provision regarding the pro rata treatment of the Banks, change the
definition of Required Banks, or change any requirement providing for the Banks
or the Required Banks to authorize the taking of any action hereunder;

provided, further, that no agreement, waiver or consent which would modify the
interests, rights or obligations of the Agent in its capacity as Agent or as the
issuer of Letters of Credit shall be effective without the written consent of
the Agent.

No Implied Waivers; Cumulative Remedies; Writing Required.

                  No course of dealing and no delay or failure of the Agent or
any Bank in exercising any right, power, remedy, or privilege under this
Agreement or any other Loan Document shall affect any other or future exercise
thereof or operate as a waiver thereof, nor shall any single or partial exercise
thereof or any abandonment or discontinuance of steps to enforce such a right,
power, remedy, or privilege preclude any further exercise thereof or of any
other right, power, remedy, or privilege. The rights and remedies of the Agent
and the Banks under this Agreement and any other Loan Documents are cumulative
and not exclusive of any rights or remedies which they would otherwise have. Any
waiver, permit, consent, or approval of any kind or character on the part of any
Bank of any breach or default under this Agreement or any such waiver of any
provision or condition of this Agreement must be in writing and shall be
effective only to the extent specifically set forth in such writing.

Reimbursement and Indemnification of Banks by the Borrower; Taxes.

                  The Borrower agrees unconditionally upon demand to pay or
reimburse to each Bank (other than the Agent, as to which the Borrower's
Obligations are set forth in Section 10.5) and to save such Bank harmless
against (i) liability for the payment of all reasonable out-of-pocket costs,
expenses, and disbursements (including fees and expenses of counsel (including
allocated costs of staff counsel) for



                                      -83-
<PAGE>   96


each Bank except with respect to (a) and (b) below), incurred by such Bank (a)
in connection with the administration and interpretation of this Agreement, and
other instruments and documents to be delivered hereunder, (b) relating to any
amendments, waivers, or consents pursuant to the provisions hereof, (c) in
connection with the enforcement of this Agreement or any other Loan Document, or
collection of amounts due hereunder or thereunder or the proof and allowability
of any claim arising under this Agreement or any other Loan Document, whether in
bankruptcy or receivership proceedings or otherwise, and (d) in any workout or
restructuring or in connection with the protection, preservation, exercise, or
enforcement of any of the terms hereof or of any rights hereunder or under any
other Loan Document or in connection with any foreclosure, collection, or
bankruptcy proceedings, or (ii) all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses, or disbursements of any
kind or nature whatsoever which may be imposed on, incurred by, or asserted
against such Bank, in its capacity as such, in any way relating to or arising
out of this Agreement or any other Loan Documents or any action taken or omitted
by such Bank hereunder or thereunder, provided that the Borrower shall not be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses, or disbursements (A) if
the same results from such Bank's gross negligence or willful misconduct, or (B)
if the Borrower was not given notice of the subject claim and the opportunity to
participate in the defense thereof, at its expense (except that the Borrower
shall remain liable to the extent such failure to give notice does not result in
a loss to the Borrower), or (C) if the same results from a compromise or
settlement agreement entered into without the consent of the Borrower, which
shall not be unreasonably withheld. The Banks will attempt to minimize the fees
and expenses of legal counsel for the Banks which are subject to reimbursement
by the Borrower hereunder by considering the usage of one law firm to represent
the Banks and the Agent if appropriate under the circumstances. The Borrower
agrees unconditionally to pay all stamp, document, transfer, recording or filing
taxes or fees and similar impositions now or hereafter determined by the Agent
or any Bank to be payable in connection with this Agreement or any other Loan
Document, and the Borrower agrees unconditionally to save the Agent and the
Banks harmless from and against any and all present or future claims,
liabilities, or losses with respect to or resulting from any omission to pay or
delay in paying any such taxes, fees, or impositions.

Holidays.

                  Whenever payment of a Loan to be made or taken hereunder shall
be due on a day which is not a Business Day such payment shall be due on the
next Business Day and such extension of time shall be included in computing
interest and fees, except that the Loans shall be due on the Business Day
preceding the Convertible Revolving Credit Expiration Date or the Revolving
Credit Expiration Date, as applicable, if the relevant expiration date is not a
Business Day. Whenever any payment or action to be made or taken hereunder
(other than payment of the Loans) shall be stated to be due on a day which is
not a Business Day, such payment or action shall be made or taken on the next
following Business Day (except as provided in Section 4.2 with respect to
Interest Periods under the Euro-Rate Option), and such extension of time shall
not be included in computing interest or fees, if any, in connection with such
payment or action.

Funding by Branch, Subsidiary, or Affiliate.

Notional Funding.

                  Each Bank shall have the right from time to time, without
notice to the Borrower, to deem any branch, Subsidiary, or Affiliate (which for
the purposes of this Section 11.5 shall mean any



                                      -84-
<PAGE>   97


corporation or association which is directly or indirectly controlled by or is
under direct or indirect common control with any corporation or association
which directly or indirectly controls such Bank) of such Bank to have made,
maintained, or funded any Loan to which the Euro-Rate Option applies at any
time, provided that immediately following (on the assumption that a payment were
then due from the Borrower to such other office), and as a result of such
change, the Borrower would not be under any greater financial obligation
pursuant to Section 5.6 than it would have been in the absence of such change.
Notional funding offices may be selected by each Bank without regard to such
Bank's actual methods of making, maintaining, or funding the Loans or any
sources of funding actually used by or available to such Bank.

                  Notwithstanding anything to the contrary contained herein, any
Bank (a "Granting Lender") may grant to a special purpose funding vehicle (an
"SPC"), identified as such in writing from time to time by the Granting Lender
to the Agent and the Borrower, the option to provide to the Borrower all or any
part of any Loan that such Granting Lender would otherwise be obligated to make
to the Borrower pursuant to the terms hereof, provided that (i) nothing herein
shall constitute a commitment to make any Loan by any SPC and (ii) if an SPC
elects not to exercise such option or otherwise fails to provide all or any part
of such Loan, the Granting Lender shall be obligated to make such Loan pursuant
to the terms hereof. The making of any Loan by an SPC hereunder shall utilize
the Commitment of the Granting Lender to the same extent, and as if, such Loan
were made by the Granting Lender. Each party hereto hereby agrees that no SPC
shall be liable for any payment under this Agreement for which its respective
Granting Lender would otherwise be liable, for so long as, and to the extent,
the related Granting Lender makes such payment. In furtherance of the foregoing,
each party hereto hereby agrees that, prior to the date that is one year and one
day after the later of (i) the payment in full of all outstanding senior
indebtedness of the relevant SPC, (ii) the payment in full of all Loans,
Reimbursement Obligations, and Letter of Credit Borrowings, and (iii) the
termination of all Commitments and the expiration or termination of all Letters
of Credit, it will not institute against, or join any other person in
instituting against, such SPC any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings or similar proceedings under the laws of
the United States or any state thereof. In addition, notwithstanding anything to
the contrary contained in this Section 11.5.1 (other than the proviso set forth
directly below in this Section 11.5.1), any SPC may (i) with notice to, but
without the prior written consent of, the Borrower or Agent and without paying
any processing fee therefor, assign all or a portion of its interests in any
Loans to its Granting Lender or to any financial institutions providing
liquidity or credit facilities to or for the account of such SPC to fund the
Loans made by such SPC or to support the securities (if any) issued by such SPC
to fund such Loans and (ii) disclose on a confidential basis any non-public
information relating to its Loans to any rating agency, commercial paper dealer
or provider of a surety, guarantee or credit or liquidity enhancement to such
SPC; provided, however, that in no event may any financial information provided
by Borrower or any other Loan Party under Section 8.3 be provided by any SPC to
any other Person. In no event shall the Borrower be obligated to pay to an SPC
that has made a Loan any greater amount than the Borrower would have been
obligated to pay under this Agreement if the Granting Lender had made such Loan.
Notwithstanding any term or condition hereof, no SPC, unless it shall have
become a Bank hereunder in accordance with the terms of Section 11.11, shall be
a party hereto or have any right to vote or give or withhold its consent under
this Agreement.

Actual Funding.

                  Each Bank shall have the right from time to time to make or
maintain any Loan by arranging for a branch, Subsidiary, or Affiliate of such
Bank to make or maintain such Loan subject to the last sentence of this Section
11.5.2. If any Bank causes a branch, Subsidiary, or Affiliate to make or
maintain any part of the Loans hereunder, all terms and conditions of this
Agreement shall, except where the context clearly requires otherwise, be
applicable to such part of the Loans to the same extent as if such Loans were
made or maintained by such Bank, but in no event shall any Bank's use of such a
branch, Subsidiary, or Affiliate to make or maintain any part of the Loans
hereunder cause such Bank or such branch, Subsidiary, or Affiliate to incur any
cost or expenses payable by the Borrower hereunder or require the Borrower to
pay any other compensation to any Bank (including any expenses incurred or
payable pursuant to Section 5.6) which would otherwise not be incurred.

Notices.

         All notices, requests, demands, directions, and other communications
(as used in this Section 11.6, collectively referred to as "notices") given to
or made upon any party hereto under the provisions of this Agreement shall be by
telephone or in writing (including telex or facsimile communication) unless
otherwise expressly permitted hereunder and shall be delivered or sent by telex
or facsimile to the respective parties at the addresses and numbers set forth
under their respective names on Schedule 1.1(B) hereof or in accordance with any
subsequent unrevoked written direction from any party to the others. All notices
shall, except as otherwise expressly herein provided, be effective (a) in the
case of telex or facsimile, when received, (b) in the case of hand-delivered
notice, when hand-delivered, (c) in the case of telephone, when telephoned,
provided, however, that in order to be effective, telephonic notices must be

Prior Understanding.

         This Agreement and the other Loan Documents (other than a Hedge
Agreement) supersede all prior understandings and agreements, whether written or
oral, between the parties hereto and thereto relating to the transactions
provided for herein and therein, including any prior confidentiality agreements
and commitments.

Duration; Survival.

         All representations and warranties of the Loan Parties contained herein
or made in connection herewith shall survive the making of Loans and issuance of
Letters of Credit and shall not be waived by the execution and delivery of this
Agreement, any investigation by the Agent or the Banks, the making of Loans,
issuance of Letters of Credit, or payment in full of the Loans. All covenants
and agreements of the Loan Parties contained in Sections 8.1, 8.2, and 8.3
herein shall continue in full force and effect from and after the date hereof so
long as the Borrower may borrow or request Letters of Credit hereunder and until
termination of the Commitments and payment in full of the Loans and expiration
or termination of all Letters of Credit. All covenants and agreements of the
Borrower contained herein relating to the payment of principal, interest,
premiums, additional compensation or expenses, and indemnification, including
those set forth in Section 5 and Sections 10.5, 10.7, and 11.3, shall survive
payment in full of the Loans, expiration or termination of the Letters of Credit
and termination of the Commitments.

Successors and Assigns.

                  (i) This Agreement shall be binding upon and shall inure to
the benefit of the Banks, the Agent, the Loan Parties, and their respective
successors and assigns, except that none of the Loan Parties may assign or
transfer any of its rights and Obligations hereunder or any interest herein.
Each Bank may, at its own cost, make assignments of or sell participations in
all or any part of its Revolving Credit Commitments and Convertible Revolving
Credit Commitments and the Loans made by it to one or more banks or other
entities, subject to the consent of the Borrower and the Agent with respect to
any assignee or participant, such consent not to be unreasonably withheld
provided that (1) no consent of the Borrower shall be required (A) if an Event
of Default exists and is continuing, or (B) in the case of an assignment by a
Bank to an Affiliate of such Bank or to another Bank, (2) any assignment by a
Bank to a Person other than an Affiliate of such Bank may not be made in amounts
less than the lesser of $5,000,000 or the amount of the assigning Bank's
Commitment, (3) a Bank may assign an interest or sell a participation in less
than 100% of its Commitments, Committed Loans, or Bid Loans, provided that
except as set forth in Section 3.4, such Bank sells an equal percentage interest
or participation in each of its Revolving Credit Commitment, Convertible
Revolving Credit Commitment, Revolving Credit Loans, and Convertible Revolving
Credit Loans, (4) a Bank may assign a Bid Loan to another Person only if it is
simultaneously assigning all or a portion of its Commitment to such Person or
such Person is already a Bank hereunder, (5) a failure of Borrower to provide
any such consent on the basis of a reasonably perceived threat to its trade
secrets or of a conflict of interest of a potential assignee shall be deemed to
be reasonable, and (6) notwithstanding any term or condition hereof, no Person
which has received a participation in any Loan or Commitment hereunder, unless
it shall have become a Bank hereunder in accordance with the terms of this
Section 11.11, shall be a party hereto or have any right to vote (except as
provided in the last sentence of this Section 11.11(i)) or give or withhold its
consent under this Agreement. In the case of an assignment, upon receipt by the
Agent of the Assignment and Assumption Agreement, the assignee shall have, to
the extent of such assignment (unless otherwise provided therein), the same
rights, benefits, and obligations as it would have if it had been a signatory
Bank hereunder, the Commitments shall be adjusted accordingly, and upon
surrender of any Revolving Credit Note or



                                      -87-
<PAGE>   100


Convertible Revolving Credit Note subject to such assignment, the Borrower shall
execute and deliver a new Revolving Credit Note or Convertible Revolving Credit
Note to the assignee, if such assignee requests such a Note in an amount equal
to the amount of the Revolving Credit Commitment or Convertible Revolving Credit
Commitment assumed by it and a new Revolving Credit Note or Convertible
Revolving Credit Note to the assigning Bank, if the assigning Bank requests such
a Note, in an amount equal to the Revolving Credit Commitment or Convertible
Revolving Credit Commitment retained by it hereunder. The assigning Bank shall
surrender its Bid Note and the Borrower shall execute and deliver to the
assignee (and to the assignor if the assignor is assigning less than all of its
Revolving Credit Commitments and Bid Loans) a new Bid Note in the form of
Exhibit 1.1(B) as appropriate. Any Bank which assigns any or all of its
Commitment or Loans to a Person other than an Affiliate of such Bank shall pay
to the Agent a service fee in the amount of $3,500 for each assignment. In the
case of a participation, no Bank shall sell any participation herein without the
consent of the Agent and the Borrower, such consent not to be unreasonably
withheld and not to be required in the instances stated above in clause (1), the
participant shall only have the rights specified in Section 9.2.3 (the
participant's rights against such Bank in respect of such participation to be
those set forth in the agreement executed by such Bank in favor of the
participant relating thereto and not to include any voting rights except with
respect to changes of the type referenced in Sections 11.1.1, 11.1.2, or
11.1.3), all of such Bank's obligations under this Agreement or any other Loan
Document shall remain unchanged, and all amounts payable by any Loan Party
hereunder or thereunder shall be determined as if such Bank had not sold such
participation.

                  (ii) Any assignee or participant which is not incorporated
under the Laws of the United States of America or a state thereof shall deliver
to the Borrower and the Agent the form of certificate described in Section 11.17
relating to federal income tax withholding. Each Bank may furnish any publicly
available information concerning any Loan Party or its Subsidiaries and any
other information concerning any Loan Party or its Subsidiaries in the
possession of such Bank from time to time to assignees and participants
(including prospective assignees or participants), provided that such assignees
and participants agree to be bound by the provisions of Section 11.12.

                  (iii) Notwithstanding any other provision in this Agreement,
any Bank may without the consent of any party hereto (a) at any time pledge or
grant a security interest in all or any portion of its rights under this
Agreement, its Note (if any) and the other Loan Documents to any Federal Reserve
Bank in accordance with Regulation A of the FRB or U.S. Treasury Regulation 31
CFR Section 203.14 (b) and assign or convey its rights under this Agreement and
the other Loan Documents in connection with the securitization of all or any
part of its assets; provided, however, that no such pledge or grant of a
security interest and no such assignment or conveyance shall release the
assignor or transferor Bank of its obligations hereunder or under any other Loan
Document and, provided further, that in no event may any financial information
provided by Borrower or any other Loan Party under Section 8.3 be provided by
any such assignee or transferee to any other Person.

Confidentiality.

General.

                  The Agent and the Banks each agree to keep confidential all
information obtained from any Loan Party or its Subsidiaries which is nonpublic
and confidential or proprietary in nature (including any information the
Borrower specifically designates as confidential), except as provided below, and
to



                                      -88-
<PAGE>   101


use such information only in connection with their respective capacities under
this Agreement and for the purposes contemplated hereby. The Agent and the Banks
shall be permitted to disclose such information (i) to outside legal counsel,
accountants and other professional advisors who need to know such information in
connection with the administration and enforcement of this Agreement, subject to
agreement of such Persons to maintain the confidentiality, (ii) to assignees and
participants as contemplated by Section 11.11, (iii) to the extent requested by
any bank regulatory authority or, with notice to the Borrower, as otherwise
required by applicable Law or by any subpoena or similar legal process, or in
connection with any investigation or proceeding arising out of the transactions
contemplated by this Agreement, (iv) if it becomes publicly available other than
as a result of a breach of this Agreement or becomes available from a source not
known to be subject to confidentiality restrictions, or (v) if the Borrower
shall have consented to such disclosure.

Sharing Information With Affiliates of the Banks.

                  Each Loan Party acknowledges that from time to time financial
advisory, investment banking, and other services may be offered or provided to
the Borrower or one or more of its Affiliates (in connection with this Agreement
or otherwise) by any Bank or by one or more Subsidiaries or Affiliates of such
Bank and each of the Loan Parties hereby authorizes each Bank to share any
information delivered to such Bank by such Loan Party and its Subsidiaries
pursuant to this Agreement, or in connection with the decision of such Bank to
enter into this Agreement, to any such Subsidiary or Affiliate of such Bank, it
being understood that any such Subsidiary or Affiliate of any Bank receiving
such information shall be bound by the provisions of Section 11.12.1 as if it
were a Bank hereunder. Such authorization shall survive the repayment of the
Loans and other Obligations and the termination of the Commitments.

Counterparts.

         This Agreement may be executed by different parties hereto on any
number of separate counterparts, each of which, when so executed and delivered,
shall be an original, and all such counterparts shall together constitute one
and the same instrument.

Agent's or Bank's Consent.

         Whenever the Agent's or any Bank's consent is required to be obtained
under this Agreement or any of the other Loan Documents as a condition to any
action, inaction, condition, or event, the Agent and each Bank shall be
authorized to give or withhold such consent in its sole and absolute discretion
and to condition its consent upon the giving of additional collateral, the
payment of money, or any other matter.

Exceptions.

         The representations, warranties, and covenants contained herein shall
be independent of each other, and no exception to any representation, warranty,
or covenant shall be deemed to be an exception to any other representation,
warranty, or covenant contained herein unless expressly provided, nor shall any
such exceptions be deemed to permit any action or omission that would be in
contravention of applicable Law.

         EACH LOAN PARTY HEREBY IRREVOCABLY CONSENTS TO THE NONEXCLUSIVE
JURISDICTION OF THE COURT OF COMMON PLEAS OF ALLEGHENY COUNTY AND THE UNITED
STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF PENNSYLVANIA, AND WAIVES
PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND CONSENTS THAT ALL SUCH
SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED MAIL DIRECTED TO SUCH LOAN

Tax Withholding Clause.

         Each Bank or assignee or participant of a Bank that is not incorporated
under the Laws of the United States of America or a state thereof agrees that it
will deliver to each of the Borrower and the Agent two (2) duly completed copies
of the following: (i) Internal Revenue Service Form W-9, 4224, or 1001, or other
applicable form prescribed by the Internal Revenue Service, certifying that such
Bank, assignee, or participant is entitled to receive payments under this
Agreement and the other Loan Documents without deduction or withholding of any
United States federal income taxes, or is subject to such tax at a reduced rate
under an applicable tax treaty, or (ii) Internal Revenue Service Form W-8 or
other applicable form or a certificate of such Bank, assignee, or participant
indicating that no such exemption or reduced rate is allowable with respect to
such payments. Each Bank, assignee, or participant required to deliver to the
Borrower and the Agent a form or certificate pursuant to the preceding sentence
shall deliver such form or certificate as follows: (A) each Bank which is a
party hereto on the Closing Date shall deliver such form or certificate at least
five (5) Business Days prior to the first date on which any interest or fees are
payable by the Borrower hereunder for the account of such Bank; (B) each
assignee or participant shall deliver such form or certificate at least five (5)
Business Days before the effective date of such assignment or participation
(unless the Agent in its sole discretion shall permit such assignee or
participant to deliver such form or certificate less than five (5) Business Days
before such date in which case it shall be due on the date specified by the
Agent). Each Bank, assignee, or participant which so delivers a Form W-8, W-9,
4224, or 1001 further undertakes to deliver to each of the Borrower and the
Agent two (2) additional copies of such form (or a successor form) on or before
the date that such form expires or becomes obsolete or after the occurrence of
any event requiring a change in the most recent form so delivered by it, and
such amendments thereto or extensions or renewals thereof as may be reasonably
requested by the Borrower or the Agent, either certifying that such Bank,
assignee or participant is entitled to receive payments under this Agreement and
the other Loan Documents without deduction or withholding of any United States
federal income taxes or is subject to such tax at a reduced rate under an
applicable tax treaty or stating that no such exemption or reduced rate is
allowable. The Agent shall be entitled to withhold United States federal income
taxes at the full withholding rate unless the Bank, assignee, or participant
establishes an exemption or that it is subject to a reduced rate as established
pursuant to the above provisions.

Joinder of Guarantors.

                 WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORPORATION

                            2000 STOCK INCENTIVE PLAN
                       (AS AMENDED THROUGH MARCH 22, 2000)

                  The purposes of the 2000 Stock Incentive Plan as amended (the
"Plan"), are to encourage eligible employees of Westinghouse Air Brake
Technologies Corporation (the "Corporation") and its Subsidiaries to increase
their efforts to make the Corporation and each Subsidiary more successful, to
provide an additional inducement for such employees to remain with the
Corporation or a Subsidiary, to reward such employees by providing an
opportunity to acquire shares of the Common Stock, par value $0.01 per share, of
the Corporation (the "Common Stock") on favorable terms and to provide a means
through which the Corporation may attract able persons to enter the employ of
the Corporation or one of its Subsidiaries. For the purposes of the Plan, the
term "Subsidiary" means any corporation in an unbroken chain of corporations
beginning with the Corporation, if each of the corporations other than the last
corporation in the unbroken chain owns stock possessing at least fifty percent
(50%) or more of the total combined voting power of all classes of stock in one
of the other corporations in the chain.


                                    SECTION 1
                                 ADMINISTRATION

                  The Plan shall be administered by a Committee (the
"Committee") appointed by the Board of Directors of the Corporation (the
"Board") and consisting of not less than two members of the Board, each of whom
at the time of appointment to the Committee and at all times during service as a
member of the Committee shall be (i) "Non-Employee Directors" as then defined
under Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the
"1934 Act"), or any successor Rule and (ii) if so determined by the Board, an
"outside director" under Section 162(m)(4)(C) of the Internal Revenue Code of
1986 (the "Code"), or any successor provision.

                  The Committee shall interpret the Plan and prescribe such
rules, regulations and procedures in connection with the operation of the Plan
as it shall deem to be necessary and advisable for the administration of the
Plan consistent with the purposes of the Plan. All questions of interpretation
and application of the Plan, or as to grants or awards under the Plan, shall be
subject to the determination of the Committee which shall be final and binding.

                  The Committee shall keep records of action taken. A majority
of the Committee shall constitute a quorum at any meeting, and the acts of a
majority of the members present at any meeting at which a quorum is present, or
acts approved in writing by all the members of the Committee, shall be the acts
of the Committee.


                                    SECTION 2
                                   ELIGIBILITY

                  Those key employees of the Corporation or any Subsidiary
(including, but not limited to, covered employees as defined in Section
162(m)(3) of the Code, or any successor provision) who share responsibility for
the management, growth or protection of the business of the Corporation or any
Subsidiary shall be eligible to be granted stock options (with or without cash
payment rights) and to receive awards of restricted shares and performance units
as described herein.

                  Subject to the provisions of the Plan, the Committee shall
have full and final authority, in its discretion, to grant stock options (with
or without cash payment rights) and to award restricted shares and performance
units as described herein and to determine the employees to whom any such grant
or award shall be made and the number of shares to be covered thereby. In
determining the eligibility of any employee, as well


<PAGE>   2


as in determining the number of shares or units covered by each grant or award
and whether cash payment rights shall be granted in conjunction with a stock
option, the Committee shall consider the position and the responsibilities of
the employee being considered, the nature and value to the Corporation or a
Subsidiary of his or her services, his or her present and/or potential
contribution to the success of the Corporation or a Subsidiary and such other
factors as the Committee may deem relevant.



                                    SECTION 3
                         SHARES AVAILABLE UNDER THE PLAN

                  The aggregate number of shares of the Common Stock that may be
issued or delivered and as to which grants or awards may be made under the Plan
is 3,600,000 shares, subject to adjustment and substitution as set forth in
Section 7. If any stock option granted under the Plan is canceled by mutual
consent or terminates or expires for any reason without having been exercised in
full, the number of shares subject thereto shall again be available for purposes
of the Plan. If shares of Common Stock are forfeited to the Corporation pursuant
to the restrictions applicable to restricted shares awarded under the Plan, the
shares so forfeited shall again be available for purposes of the Plan. To the
extent any award of performance units is not earned or is paid in cash rather
than shares, the number of shares covered thereby shall again be available for
purposes of the Plan.

                  The shares which may be issued or delivered under the Plan may
be either authorized but unissued shares or treasury shares or partly each, as
shall be determined from time to time by the Board.


                                    SECTION 4
                             GRANT OF STOCK OPTIONS
                      AND CASH PAYMENT RIGHTS AND AWARD OF
                     RESTRICTED SHARES AND PERFORMANCE UNITS

                  The Committee shall have authority, in its discretion, (i) to
grant "incentive stock options" pursuant to Section 422 of the Code, to grant
"nonstatutory stock options" (i.e., stock options which do not qualify under
Sections 422 or 423 of the Code) or to grant both types of stock options (but
not in tandem), (ii) to award restricted shares and (iii) to award performance
units, all as provided herein. The Committee also shall have the authority, in
its discretion, to grant cash payment rights in conjunction with nonstatutory
stock options with the effect provided in Section 5(D). Cash payment rights may
not be granted in conjunction with incentive stock options. Cash payment rights
granted in conjunction with a nonstatutory stock option may be granted either at
the time the stock option is granted or at any time thereafter during the term
of the stock option.

                  During the duration of the Plan, the maximum number of shares
as to which stock options may be granted and as to which shares may be awarded
under the Plan to any one employee is 800,000 shares, subject to adjustment and
substitution as set forth in Section 7. For the purposes of this limitation, any
adjustment or substitution made pursuant to Section 7 with respect to the
maximum number of shares set forth in the preceding sentence shall also be made
with respect to any shares subject to stock options or share awards previously
granted under the Plan to such employee.

                  Notwithstanding any other provision contained in the Plan or
in any agreement referred to in Section 5(H), but subject to the possible
exercise of the Committee's discretion contemplated in the last sentence of this
paragraph, the aggregate fair market value, determined as provided in Section
5(I) on the date of grant, of the shares with respect to which incentive stock
options are exercisable for the first time by an employee during any calendar
year under all plans of the corporation employing such employee, any parent or
subsidiary corporation of such corporation and any predecessor corporation of
any such corporation shall not exceed $100,000. If the date on which one or more
of such incentive stock options could first be exercised would be accelerated
pursuant to any provision of the Plan or any stock option agreement, and the
acceleration of such exercise date would result in a violation of the limitation
set forth in the preceding sentence, then, notwithstanding any such provision,
but subject to the provisions of the next succeeding sentence, the exercise
dates of such incentive stock options shall be accelerated only to the date or
dates, if any, that do not result in a violation of such limitation and, in such
event, the exercise dates of the incentive stock options with the lowest



                                       2
<PAGE>   3


option prices shall be accelerated to the earliest such dates. The Committee
may, in its discretion, authorize the acceleration of the exercise date of one
or more incentive stock options even if such acceleration would violate the
$100,000 limitation set forth in the first sentence of this paragraph and even
if such incentive stock options are thereby converted in whole or in part to
nonstatutory stock options.


                                    SECTION 5
                             TERMS AND CONDITIONS OF
                      STOCK OPTIONS AND CASH PAYMENT RIGHTS

                  Stock options and cash payment rights granted under the Plan
shall be subject to the following terms and conditions:

                  (A) The purchase price at which each stock option may be
exercised (the "option price") shall be such price as the Committee, in its
discretion, shall determine, but shall not be less than one hundred percent
(100%) of the fair market value per share of the Common Stock covered by the
stock option on the date of grant, except that in the case of an incentive stock
option granted to an employee who, immediately prior to such grant, owns stock
possessing more than (10%) of the total combined voting power of all classes of
stock of the Corporation or any Subsidiary (a "Ten Percent Employee"), the
option price shall be one hundred ten percent (110%) of such fair market value
on the date of grant; provided, however, that with respect to employees who
become employees of the Corporation or any Subsidiary as a result of the
acquisition by the Corporation or any Subsidiary of the stock or assets of
another entity or business (an "Acquisition"), and who are not deemed to be
reporting persons of the Corporation or any Subsidiary for purposes of Section
16(b) of the 1934 Act, the option price with respect to nonstatutory stock
options granted to such persons within 12 months of such Acquisition shall be
such price as the Committee, in its discretion, shall determine, which may be
less than the fair market value per share of the Common Stock on the date of
grant. For purposes of this Section 5(A), the fair market value of the Common
Stock shall be determined as provided in Section 5(I). For purposes of this
Section 5(A), an individual (i) shall be considered as owning not only shares of
stock owned individually but also all shares of stock that are at the time
owned, directly or indirectly, by or for the spouse, ancestors, lineal
descendants and brothers and sisters (whether by the whole or half blood) of
such individual and (ii) shall be considered as owning proportionately any
shares owned, directly or indirectly, by or for any corporation, partnership,
estate or trust in which such individual is a stockholder, partner or
beneficiary.

                  (B) The option price for each stock option shall be payable in
cash in United States dollars (including check, bank draft or money order);
provided, however, that in lieu of cash the person exercising the stock option
may (if authorized by the Committee at the time of grant in the case of an
incentive stock option, or at any time in the case of a nonstatutory stock
option) pay the option price in whole or in part by delivering to the
Corporation shares of the Common Stock having a fair market value on the date of
exercise of the stock option, determined as provided in Section 5(I), equal to
the option price for the shares being purchased, except that (i) any portion of
the option price representing a fraction of a share shall in any event be paid
in cash and (ii) no shares of the Common Stock which have been held for less
than six months may be delivered in payment of the option price of a stock
option. Delivery of shares, if authorized, may also be accomplished through the
effective transfer to the Corporation of shares held by a broker or other agent.
The Corporation will also cooperate with any person exercising a stock option
who participates in a cashless exercise program of a broker or other agent under
which all or part of the shares received upon exercise of the stock option are
sold through the broker or other agent or under which the broker or other agent
makes a loan to such person. Notwithstanding the foregoing, unless the
Committee, in its discretion, shall otherwise determine at the time of grant in
the case of an incentive stock option, or at any time in the case of a
nonstatutory stock option, the exercise of the stock option shall not be deemed
to occur and no shares of Common Stock will be issued or delivered by the
Corporation upon exercise of the stock option until the Corporation has received
payment of the option price in full. The date of exercise of a stock option
shall be determined under procedures established by the Committee, and as of the
date of exercise the person exercising the stock option shall be considered for
all purposes to be the owner of the shares with respect to which the stock
option has been exercised. Payment of the option price with shares shall not
increase the number of shares of the Common Stock which may be issued or
delivered under the Plan as provided in Section 3.

<PAGE>   4


                  (C) Unless the Committee, in its discretion, shall otherwise
determine, stock options shall be exercisable by a grantee during employment
commencing on the date of grant. No stock option shall be exercisable after the
expiration of ten years (five years in the case of an incentive stock option
granted to a Ten Percent Employee) from the date of grant. Unless the Committee,
in its discretion, shall otherwise determine, a stock option to the extent
exercisable at any time may be exercised in whole or in part.

                  (D) Cash payment rights granted in conjunction with a
nonstatutory stock option shall entitle the person who is entitled to exercise
the stock option, upon exercise of the stock option or any portion thereof, to
receive cash from the Corporation (in addition to the shares to be received upon
exercise of the stock option) equal to such percentage as the Committee, in its
discretion, shall determine not greater than one hundred percent (100%) of the
excess of the fair market value of a share of the Common Stock on the date of
exercise of the stock option over the option price per share of the stock option
times the number of shares covered by the stock option, or portion thereof,
which is exercised. Payment of the cash provided for in this Section 5(D) shall
be made by the Corporation as soon as practicable after the time the amount
payable is determined. For purposes of this Section 5(D), the fair market value
of the Common Stock shall be determined as provided in Section 5(I).

                  (E) (i) No stock option shall be transferable by the grantee
otherwise than by Will, or if the grantee dies intestate, by the laws of descent
and distribution of the state of domicile of the grantee at the time of death
and (ii) all stock options shall be exercisable during the lifetime of the
grantee only by the grantee.

                  (F) Subject to the provisions of Section 4 in the case of
incentive stock options, unless the Committee, in its discretion, shall
otherwise determine:

                           (i) If the employment of a grantee who is not
                  disabled within the meaning of Section 422(c)(6) of the Code
                  (a "Disabled Grantee") is voluntarily terminated with the
                  consent of the Corporation or a Subsidiary or a grantee
                  retires under any retirement plan of the Corporation or a
                  Subsidiary, any then outstanding incentive stock option held
                  by such grantee shall be exercisable by the grantee (but only
                  to the extent exercisable by the grantee immediately prior to
                  the termination of employment) at any time prior to the
                  expiration date of such incentive stock option or within three
                  months after the date of termination of employment, whichever
                  is the shorter period;

                           (ii) If the employment of a grantee who is not a
                  Disabled Grantee is voluntarily terminated with the consent of
                  the Corporation or a Subsidiary or a grantee retires under any
                  retirement plan of the Corporation or a Subsidiary any then
                  outstanding nonstatutory stock option held by such grantee
                  shall be exercisable by the grantee (but only to the extent
                  exercisable by the grantee immediately prior to termination of
                  employment) at any time prior to the expiration date of such
                  nonstatutory stock option or within one year after the date of
                  termination of employment, whichever is the shorter period;

                           (iii) If the employment of a grantee who is a
                  Disabled Grantee is voluntarily terminated with the consent of
                  the Corporation or a Subsidiary, any then outstanding stock
                  option held by such grantee shall be exercisable by the
                  grantee in full (whether or not so exercisable by the grantee
                  immediately prior to the termination of employment) by the
                  grantee at any time prior to the expiration date of such stock
                  option or within one year after the date of termination of
                  employment, whichever is the shorter period;

                           (iv) Following the death of a grantee during
                  employment, any outstanding stock option held by the grantee
                  at the time of death shall be exercisable in full (whether or
                  not so exercisable by the grantee immediately prior to the
                  death of the grantee) by the person entitled to do so under
                  the Will of the grantee, or, if the grantee shall fail to make
                  testamentary disposition of the stock option or shall die
                  intestate, by the legal representative of the grantee at any
                  time prior to the expiration date of such stock option or
                  within one year after the date of death of the grantee,
                  whichever is the shorter period;



                                       4
<PAGE>   5


                           (v) Following the death of a grantee after
                  termination of employment during a period when a stock option
                  is exercisable, the stock option shall be exercisable by such
                  person entitled to do so under the Will of the grantee or by
                  such legal representative (but only to the extent the stock
                  option was exercisable by the grantee immediately prior to the
                  death of the grantee) at any time prior to the expiration date
                  of such stock option or within one year after the date of
                  death, whichever is the shorter period;

                           (vi) Unless the exercise period of a stock option
                  following termination of employment has been extended as
                  provided in Section 8(C), if the employment of a grantee
                  terminates for any reason other than voluntary termination
                  with the consent of the Corporation or a Subsidiary,
                  retirement under any retirement plan of the Corporation or a
                  Subsidiary or death, all outstanding stock options held by the
                  grantee at the time of such termination of employment shall
                  automatically terminate.

Whether termination of employment is a voluntary termination with the consent of
the Corporation or a Subsidiary shall be determined, in its discretion, by the
Committee and any such determination by the Committee shall be final and
binding.

                  (G) If a grantee of a stock option (i) engages in the
operation or management of a business (whether as owner, partner, officer,
director, employee or otherwise and whether during or after termination of
employment) which is in competition with the Corporation or any of its
Subsidiaries (provided, however, that this clause shall not apply if Section
8(C) applies following termination of employment), (ii) induces or attempts to
induce any customer, supplier, licensee or other individual, corporation or
other business organization having a business relationship with the Corporation
or any of its Subsidiaries to cease doing business with the Corporation or any
of its Subsidiaries or in any way interferes with the relationship between any
such customer, supplier, licensee or other person and the Corporation or any of
its Subsidiaries or (iii) solicits any employee of the Corporation or any of its
Subsidiaries to leave the employment thereof or in any way interferes with the
relationship of such employee with the Corporation or any of its Subsidiaries,
the Committee, in its discretion, may immediately terminate all outstanding
stock options held by the grantee. Whether a grantee has engaged in any of the
activities referred to in the preceding sentence which would cause the
outstanding stock options to be terminated shall be determined, in its
discretion, by the Committee, and any such determination by the Committee shall
be final and binding.

                  (H) All stock options and cash payment rights shall be
confirmed by an agreement which shall be executed on behalf of the Corporation
by the Chief Executive Officer (if other than the President), the President or
any Vice President and by the grantee. The agreement confirming a stock option
shall specify whether the stock option is an incentive stock option or a
nonstatutory stock option. The provisions of such agreements need not be
identical.

                  (I) Fair market value of the Common Stock shall be the mean
between the following prices, as applicable, for the date as of which fair
market value is to be determined as quoted in The Wall Street Journal (or in
such other reliable publication as the Committee, in its discretion, may
determine to rely upon): (i) if the Common Stock is listed on the New York Stock
Exchange, the highest and lowest sales prices per share of the Common Stock as
quoted in the NYSE-Composite Transactions listing for such date, (ii) if the
Common Stock is not listed on such exchange the highest and lowest sales prices
per share of Common Stock for such date on (or on any composite index including)
the principal United States securities exchange registered under the 1934 Act on
which the Common Stock is listed or (iii) if the Common Stock is not listed on
any such exchange, the highest and lowest sales prices per share of the Common
Stock for such date on the National Association of Securities Dealers Automated
Quotations System or any successor system then in use ("NASDAQ"). If there are
no such sale price quotations for the date as of which fair market value is to
be determined but there are such sale price quotations within a reasonable
period both before and after such date, then fair market value shall be
determined by taking a weighted average of the means between the highest and
lowest sales prices per share of the Common Stock as so quoted on the nearest
date before and the nearest date after the date as of which fair market value is
to be determined. The average should be weighted inversely by the respective
numbers of trading days between the selling dates and the date as of which fair
market value is to be determined. If there are no such sale price quotations on
or within a reasonable period both before and after the date as of which fair
market value is to be determined, then fair market value of the Common Stock
shall be the mean between the



                                       5
<PAGE>   6


bona fide bid and asked prices per share of Common Stock as so quoted for such
date on NASDAQ, or if none, the weighted average of the means between such bona
fide bid and asked prices on the nearest trading date before and the nearest
trading date after the date as of which fair market value is to be determined,
if both such dates are within a reasonable period. The average is to be
determined in the manner described above in this Section 5(I). If the fair
market value of the Common Stock cannot be determined on any basis previously
set forth in this Section 5(I) for the date as of which fair market value is to
be determined, the Committee shall in good faith determine the fair market value
of the Common Stock on such date. Fair market value shall be determined without
regard to any restriction other than a restriction which, by its terms, will
never lapse.

                  (J) The obligation of the Corporation to issue or deliver
shares of the Common Stock under the Plan shall be subject to (i) the
effectiveness of a registration statement under the Securities Act of 1933, as
amended, with respect to such shares, if deemed necessary or appropriate by
counsel for the Corporation, (ii) the condition that the shares shall have been
listed (or authorized for listing upon official notice of issuance) upon each
stock exchange, if any, on which the Common Stock may then be listed and (iii)
all other applicable laws, regulations, rules and orders which may then be in
effect.

                  Subject to the foregoing provisions of this Section 5 and the
other provisions of the Plan, stock options and cash payment rights granted
under the Plan shall be subject to such restrictions and other terms and
conditions, if any, as shall be determined, in its discretion, by the Committee
and set forth in the agreement referred to in Section 5(H), or an amendment
thereto.


                                    SECTION 6
                     RESTRICTED SHARES AND PERFORMANCE UNITS

(A) RESTRICTED SHARES

                  Awards of restricted shares shall be confirmed by a written
agreement in the form prescribed by the Committee in its discretion, which shall
set forth the number of shares of the Common Stock awarded, restrictions imposed
thereon (including, without limitation, restrictions on the right of the grantee
to sell, assign, transfer or encumber such shares (except as provided below)
while such shares are subject to other restrictions imposed under this Section
6(A)), the duration of such restrictions, events (which may, in the discretion
of the Committee, include termination of employment and/or performance-based
events) the occurrence of which would cause a forfeiture of the restricted
shares and such other terms and conditions as shall be determined, in its
discretion, by the Committee. The agreement shall be executed on behalf of the
Corporation by the Chief Executive Officer (if other than the President), the
President or any Vice President and by the grantee. The provisions of such
agreements need not be identical. Awards of restricted shares shall be effective
on the date determined, in its discretion, by the Committee.

                  Following the award of restricted shares and prior to the
lapse or termination of the applicable restrictions, share certificates for the
restricted shares shall be issued or delivered in the name of the grantee and
deposited with the Corporation in escrow together with related stock powers
signed by the grantee. Except as provided in Section 7, the Committee, in its
discretion, may determine that dividends and other distributions on the shares
held in escrow shall not be paid to the grantee until the lapse or termination
of the applicable restrictions. Unless otherwise provided, in its discretion, by
the Committee, any such dividends or other distributions shall not bear
interest. Upon the lapse or termination of the applicable restrictions (and not
before such time), the grantee shall receive the share certificates for the
restricted shares (subject to the provisions of Section 10) and unpaid
dividends, if any. From the date the award of restricted shares is effective,
the grantee shall be a stockholder with respect to all the shares represented by
the share certificates and shall have all the rights of a stockholder with
respect to all the restricted shares, including the right to vote such shares
and to receive all dividends and other distributions paid with respect to such
shares, subject only to the preceding provisions of this paragraph and the other
restrictions imposed by the Committee. If a grantee of restricted shares (i)
engages in the operation or management of a business (whether as owner, partner,
officer, director, employee or otherwise and whether during or after termination
of employment) which is in competition with the Corporation or any of its
Subsidiaries (provided, however, that this clause shall not apply if Section
8(D) applies), (ii) induces or attempts to induce any customer, supplier,
licensee or other individual, corporation or



                                       6
<PAGE>   7


other business organization having a business relationship with the Corporation
or any of its Subsidiaries to cease doing business with the Corporation or any
of its Subsidiaries or in any way interferes with the relationship between any
such customer, supplier, licensee or other person and the Corporation or any of
its Subsidiaries or (iii) solicits any employee of the Corporation or any of its
Subsidiaries to leave the employment thereof or in any way interferes with the
relationship of such employee with the Corporation or any of its Subsidiaries,
the Committee may immediately declare forfeited all restricted shares held by
the grantee as to which the restrictions have not yet lapsed. Whether a grantee
has engaged in any of the activities referred to in the preceding sentence which
would cause the restricted shares to be forfeited shall be determined, in its
discretion, by the Committee, and any such determination by the Committee shall
be final and binding.

                  Neither this Section 6(A) nor any other provision of the Plan
shall preclude a grantee from transferring or assigning restricted shares to (i)
the trustee of a trust that is revocable by such grantee alone, both at the time
of the transfer or assignment and at all times thereafter prior to such
grantee's death or (ii) the trustee of any other trust to the extent approved in
advance by the Committee in writing. A transfer or assignment of restricted
shares from such trustee to any person other than such grantee shall be
permitted only to the extent approved in advance by the Committee in writing,
and restricted shares held by such trustee shall be subject to all of the
conditions and restrictions set forth in the Plan and in the applicable
agreement as if such trustee were a party to such agreement.

(B) PERFORMANCE UNITS

                  The Committee may award performance units which shall be
earned by an awardee based on the level of performance over a specified period
of time by the Corporation, a Subsidiary or Subsidiaries, any branch, department
or other portion thereof or the awardee individually, as determined by the
Committee. For the purposes of the grant of performance units, the following
definitions shall apply:

                  (i) "Performance unit" shall mean an award, expressed in
         dollars or shares of Common Stock, granted to an awardee with respect
         to a Performance Period. Awards expressed in dollars may be established
         as fixed dollar amounts, as a percentage of salary, as a percentage of
         a pool based on earnings of the Corporation, a Subsidiary or
         Subsidiaries or any branch, department or other portion thereof or in
         any other manner determined by the Committee in its discretion,
         provided that the amount thereof shall be capable of being determined
         as a fixed dollar amount as of the close of the Performance Period.

                  (ii) "Performance Period" shall mean an accounting period of
         the Corporation or a Subsidiary of not less than one year, as
         determined by the Committee in its discretion.

                  (iii) "Performance Target" shall mean that level of
         performance established by the Committee which must be met in order for
         the performance unit to be fully earned. The Performance Target may be
         expressed in terms of earnings per share, return on assets, asset
         growth, ratio of capital to assets or such other level or levels of
         accomplishment by the Corporation, a Subsidiary or Subsidiaries, any
         division, branch, department or other portion thereof or the awardee
         individually as may be established or revised from time to time by the
         Committee.

                  (iv) "Minimum Target" shall mean a minimal level of
         performance established by the Committee which must be met before any
         part of the performance unit is earned. The Minimum Target may be the
         same as or less than the Performance Target in the discretion of the
         Committee.

                  (v) "Performance shares" shall mean shares of Common Stock
         issued or delivered in payment of earned performance units.

                  An awardee shall earn the performance unit in full by meeting
the Performance Target for the Performance Period. If the Minimum Target has not
been attained at the end of the Performance Period, no part of the performance
unit shall have been earned by the awardee. If the Minimum Target is attained
but the Performance Target is not attained, the portion of the performance unit
earned by the awardee shall be determined on the basis of a formula established
by the Committee.



                                       7
<PAGE>   8


                  At any time prior to the end of a Performance Period, the
Committee may adjust downward (but not upward) the Performance Target and/or
Minimum Target as a result of major events unforeseen at the time of the award,
such as changes in the economy, in the industry or laws affecting the operations
of the Corporation or a Subsidiary, or any division, branch, department or other
portion thereof, or any other event the Committee determines would have a
significant impact upon the probability of attaining the previously established
Performance Target.

                  Payment of earned performance units shall be made to awardees
following the close of the Performance Period as soon as practicable after the
time the amount payable is determined by the Committee. Payment in respect of
earned performance units, whether expressed in dollars or shares, may be made in
cash, in shares of Common Stock, or partly in cash and partly in shares of
Common Stock, as determined by the Committee at the time of payment. For this
purpose, performance units expressed in dollars shall be converted to shares,
and performance units expressed in shares shall be converted to dollars, based
on the fair market value of the Common Stock, determined as provided in Section
5(I), as of the date the amount payable is determined by the Committee. The
Committee, in its discretion, may determine that awardees shall also be entitled
to any dividends or other distributions that would have been paid on earned
performance shares had the shares been outstanding during the period from the
award to the payment of the performance shares. Unless otherwise provided, in
its discretion, by the Committee, any such dividends or other distributions
shall not bear interest.

                  Unless otherwise provided in the agreement confirming the
award of the performance units, if prior to the close of a Performance Period,
the employment of an awardee of performance units is voluntarily terminated with
the consent of the Corporation or a Subsidiary, the grantee retires under any
retirement plan of the Corporation or a Subsidiary or the grantee dies during
employment, the Committee in its discretion may determine to pay to the grantee
all or part of the performance unit based upon the extent to which the Committee
determines the Performance Target or Minimum Target has been achieved as of the
date of termination of employment, retirement or death, the period of time
remaining until the end of the Performance Period and/or such other factors as
the Committee may deem relevant. If the Committee, in its discretion, determines
that all or any part of the performance unit shall be paid, payment shall be
made to the awardee or the estate of the awardee as promptly as practicable
following such determination and may be made in cash, in shares of Common Stock,
or partly in cash and partly in shares of Common Stock, as determined by the
Committee at the time of payment. For this purpose, performance units expressed
in dollars shall be converted to shares, and performance units expressed in
shares shall be converted to dollars, based on the fair market value of the
Common Stock, determined as provided in Section 5(I), as of the date the amount
payable is determined by the Committee.

                  Except as otherwise provided in Section 8(E), if the
employment of a grantee of an award of performance units terminates prior to the
close of the Performance Period for any reason other than voluntary termination
with the consent of the Corporation or a Subsidiary, retirement under any
retirement plan of the Corporation or a Subsidiary or death, the unearned
performance units shall be deemed not to have been earned and such unearned
units shall not be paid.

                  Whether termination of employment is a voluntary termination
with the consent of the Corporation or a Subsidiary shall be determined, in its
discretion, by the Committee and any such determination by the Committee shall
be final and binding.

                  If an awardee of performance units (i) engages in the
operation or management of a business (whether as owner, partner, officer,
director, employee or otherwise and whether during or after termination of
employment) which is in competition with the Corporation or any of its
Subsidiaries (provided, however, that this clause shall not apply if Section
8(E) applies), (ii) induces or attempts to induce any customer, supplier,
licensee or other individual, corporation or other business organization having
a business relationship with the Corporation or any of its Subsidiaries to cease
doing business with the Corporation or any of its Subsidiaries or in any way
interferes with the relationship between any such customer, supplier, licensee
or other person and the Corporation or any of its Subsidiaries or (iii) solicits
any employee of the Corporation or any of its Subsidiaries to leave the
employment thereof or in any way interferes with the relationship of such
employee with the Corporation or any of its Subsidiaries, the Committee may
immediately cancel the award. Whether an awardee has engaged in any of the
activities referred to the preceding sentence which would cause the award of


                                       8
<PAGE>   9


performance units to be canceled shall be determined, in its discretion, by the
Committee, and any such determination by the Committee shall be final and
binding.

                  Performance unit awards shall be evidenced by a written
agreement in the form prescribed by the Committee which shall set forth the
amount or manner of determining the amount of the performance unit, the
Performance Period, the Performance Target and any Minimum Target and such other
terms and conditions as the Committee in its discretion deems appropriate.
Performance unit awards shall be effective only upon execution of the applicable
performance unit agreement on behalf of the Corporation by the Chief Executive
Officer (if other than the President), the President or any Vice President, and
by the awardee.


                                    SECTION 7
                      ADJUSTMENT AND SUBSTITUTION OF SHARES

                  If a dividend or other distribution shall be declared upon the
Common Stock payable in shares of the Common Stock, (i) the number of shares of
the Common Stock subject to any outstanding stock options or performance unit
awards, (ii) the number of shares of the Common Stock which may be issued or
delivered under the Plan but are not subject to outstanding stock options or
performance unit awards and (iii) the maximum number of shares as to which stock
options may be granted and as to which shares may be awarded under the Plan to
any employee under Section 4 on the date fixed for determining the stockholders
entitled to receive such stock dividend or distribution shall be adjusted by
adding thereto the number of shares of the Common Stock which would have been
distributable thereon if such shares had been outstanding on such date. Shares
of Common Stock so distributed with respect to any restricted shares held in
escrow shall also be held by the Corporation in escrow and shall be subject to
the same restrictions as are applicable to the restricted shares on which they
were distributed.

                  If the outstanding shares of Common Stock shall be changed
into or exchangeable for a different number or kind of shares of stock or other
securities of the Corporation or another corporation, whether through
reorganization, reclassification, recapitalization, stock split-up, combination
of shares, merger or consolidation, then there shall be substituted for each
share of the Common Stock subject to any then outstanding stock option or
performance unit award, for each share of the Common Stock which may be issued
or delivered under the Plan but which is not then subject to any outstanding
stock option or performance unit award and for the maximum number of shares as
to which stock options may be granted and as to which shares may be awarded
under the Plan to any employee under Section 4, the number and kind of shares of
stock or other securities into which each outstanding share of the Common Stock
shall be so changed or for which each such share shall be exchangeable. Unless
otherwise determined by the Committee, in its discretion, any such stock or
securities, as well as any cash or other property, into or for which any
restricted shares held in escrow shall be changed or exchangeable in any such
transaction shall also be held by the Corporation in escrow and shall be subject
to the same restrictions as are applicable to the restricted shares in respect
of which such stock, securities, cash or other property was issued or
distributed.

                  In case of any adjustment or substitution as provided for in
the first two paragraphs of this Section 7, the aggregate option price for all
shares subject to each then outstanding stock option prior to such adjustment or
substitution shall be the aggregate option price for all shares of stock or
other securities (including any fraction) to which such shares shall have been
adjusted or which shall have been substituted for such shares.

                  Any new option price per share shall be carried to at least
three decimal places with the last decimal place rounded upwards to the nearest
whole number.

                  If the outstanding shares of the Common Stock shall be changed
in value by reason of any spin-off, split-off or split-up, or dividend in
partial liquidation, dividend in property other than cash or extraordinary
distribution to holders of the Common Stock, (i) the Committee shall make any
adjustments to any then outstanding stock option which it determines are
equitably required to prevent dilution or enlargement of the rights of grantees
which would otherwise result from any such transaction, and (ii) unless
otherwise determined by the Committee, in its discretion, any stock, securities,
cash or other property distributed with respect to any restricted shares held in
escrow or for which any restricted shares held in escrow shall be exchanged in
any such transaction shall also be held by the Corporation in escrow and shall
be subject to the same restrictions as are



                                       9
<PAGE>   10


applicable to the restricted shares in respect of which such stock, securities,
cash or other property was distributed or exchanged.

                  No adjustment or substitution provided for in this Section 7
shall require the Corporation to issue or sell a fraction of a share or other
security. Accordingly, all fractional shares or other securities which result
from any such adjustment or substitution shall be eliminated and not carried
forward to any subsequent adjustment or substitution. Owners of restricted
shares held in escrow shall be treated in the same manner as owners of Common
Stock not held in escrow with respect to fractional shares created by an
adjustment or substitution of shares, except that, unless otherwise determined
by the Committee, in its discretion, any cash or other property paid in lieu of
a fractional share shall be subject to restrictions similar to those applicable
to the restricted shares exchanged therefor.

                  If any adjustment or substitution provided for in this Section
7 requires the approval of stockholders in order to enable the Corporation to
grant incentive stock options or to comply with Section 162(m) of the Code, then
no such adjustment or substitution shall be made without the required
stockholder approval. Notwithstanding the foregoing, in the case of incentive
stock options, if the effect of any such adjustment or substitution would be to
cause the stock option to fail to continue to qualify as an incentive stock
option or to cause a modification, extension or renewal of such stock option
within the meaning of Section 424 of the Code, the Committee may elect that such
adjustment or substitution not be made but rather shall use reasonable efforts
to effect such other adjustment of each then outstanding stock option as the
Committee, in its discretion, shall deem equitable and which will not result in
any disqualification, modification, extension or renewal (within the meaning of
Section 424 of the Code) of the incentive stock option.

                  Except as provided in this Section 7, a grantee shall have no
rights by reason of any issue or delivery by the Corporation of stock of any
class or securities convertible into stock of any class, any subdivision or
consolidation of shares of stock of any class, the payment of any stock dividend
or any other increase or decrease in the number of shares of stock of any class.


                                    SECTION 8

provided, however, that (i) if securities beneficially owned by a grantee are
included in determining the Beneficial Ownership of a Person referred to in
paragraph 7(a) above, (ii) a grantee is required to be named pursuant to Item 2

above, then no Section 8 Event with respect to such grantee shall be deemed to
have occurred by reason of such event.

(B) ACCELERATION OF THE EXERCISE DATE OF STOCK OPTIONS

                  Subject to the provisions of Section 4 in the case of
incentive stock options, unless the agreement referred to in Section 5(H), or an
amendment thereto, shall otherwise provide, notwithstanding any other provision
contained in the Plan, in case any "Section 8 Event" occurs all outstanding
stock options (other than those held by a person referred to in the proviso to
Section 8(A)(7)) shall become immediately and fully exercisable whether or not
otherwise exercisable by their terms.


(C) EXTENSION OF THE EXPIRATION DATE OF STOCK OPTIONS

                  Subject to the provisions of Section 4 in the case of

amendment thereto, shall otherwise provide, notwithstanding any other provision
contained in the Plan, all outstanding stock options held by a grantee (other
than a grantee referred to in the proviso to Section 8(A)(7)) whose employment
with the Corporation or a Subsidiary terminates within



                                       11
<PAGE>   12


one year of any Section 8 Event for any reason other than voluntary termination
with the consent of the Corporation or a Subsidiary, retirement under any
retirement plan of the Corporation or a Subsidiary or death which are
exercisable shall continue to be exercisable for a period of three years from
the date of such termination of employment, but in no event after the expiration
date of the stock option.


(D) LAPSE OF RESTRICTIONS ON RESTRICTED SHARE AWARDS

                  Unless the agreement referred to in Section 6(A), or an
amendment thereto, shall otherwise provide, notwithstanding any other provision
contained in the Plan, if any "Section 8 Event" occurs prior to the scheduled
lapse of all restrictions applicable to restricted share awards under the Plan
(other than those held by a person referred to in the proviso to Section
8(A)(7)), all such restrictions shall lapse upon the occurrence of any such
"Section 8 Event" regardless of the scheduled lapse of such restrictions.


(E) PAYMENT OF PERFORMANCE UNITS

                  Unless the agreement referred to in Section 6(B), or an
amendment thereto, shall otherwise provide, notwithstanding any other provision
contained in the Plan, if any "Section 8 Event" occurs prior to the end of any
Performance Period, all performance units (unless the awardee is a person
referred to in the proviso to Section 8(A)(7)) shall be deemed to have been
fully earned as of the date of the Section 8 Event, regardless of the attainment
or nonattainment of any Performance Target or any Minimum Target and shall be
paid to the awardee thereof as promptly as practicable after the Section 8
Event. If the performance unit is not expressed as a fixed amount in dollars or
shares, the Committee may provide in the performance unit agreement for the
amount to be paid in the case of Section 8 Event.


(F) TAX-RELATED CASH PAYMENTS

                  Unless the agreements referred to in Sections 5(H), 6(A) or
6(B), or an amendment thereto, shall otherwise provide, if the independent
auditors most recently selected by the Board determine that (i) any grant,
payment or transfer to or for the benefit of a grantee or awardee under the Plan
(whether granted, paid or payable or transferred or transferable pursuant to the
Plan or otherwise) (a "Payment") would be deemed to be an "excess parachute
payment" for Federal income tax purposes because of Section 280G of the Code, or
any successor provision ("Section 280G"), and (ii) any grant, payment or
transfer under the Plan to or for the benefit of a grantee or awardee within one
year of or following the occurrence of a Section 8 Event constitutes in whole or
in part a "parachute payment" under Section 280G (without regard to Section
280G(b)(4)) used in calculating such "excess parachute payment," the Payment
will be grossed up through the payment by the Corporation to the grantee or
awardee in cash of the amount of any excise tax under Section 4999 of the Code,
or any successor provision ("Section 4999"), on the "excess parachute payment"
and the amount of any excise tax under Section 4999 and applicable income tax on
the total amount of such gross up payment, so that the grantee or awardee will
receive the full amount of the Payment after the grantee or awardee has paid any
excise tax under Section 4999 of the Code on the "excess parachute payment" and
any excise tax under Section 4999 and applicable income tax on the amount of
such gross up payment. On the later of the date an "excess parachute payment" is
paid to or for the benefit of the grantee or awardee or the date on which it can
be first determined that a Payment would be deemed to be an "excess parachute
payment," the Corporation shall pay or distribute to or for the benefit of the
grantee or awardee the gross up payment due to the grantee or awardee under this
Section 8(F).


                                    SECTION 9
           EFFECT OF THE PLAN ON THE RIGHTS OF EMPLOYEES AND EMPLOYER

                  Neither the adoption of the Plan nor any action of the Board
or the Committee pursuant to the Plan shall be deemed to give any employee any
right to be granted a stock option (with or without cash payment rights) or to
be awarded restricted shares or performance units under the Plan. Nothing in the
Plan, in any stock option or cash payment rights granted under the Plan or in
any award of restricted shares or performance units under the Plan or in any
agreement providing for any of the foregoing shall confer any right on any
employee to



                                       12
<PAGE>   13


continue in the employ of the Corporation or any Subsidiary or interfere in any
way with the rights of the Corporation or any Subsidiary to terminate the
employment of any employee at any time.


                                   SECTION 10
                                  WITHHOLDING

                  Income, excise or employment taxes may be required to be
withheld by the Corporation or a Subsidiary in connection with the grant or
exercise of a stock option, upon a "disqualifying disposition" of the shares
acquired upon exercise of an incentive stock option, at the time restricted
shares are granted or vest or performance units are earned or upon the receipt
by the grantee of cash in payment of cash payment rights or dividends on
restricted stock which has not vested. Any taxes required to be withheld by the
Corporation or any of its Subsidiaries upon the receipt by the grantee of cash
in payment of cash payment rights or dividends will be satisfied by the
Corporation by withholding the taxes required to be withheld from the cash the
grantee would otherwise receive. The Corporation will request that the grantee
pay any additional amount required to be withheld directly to the Corporation in
cash. If a grantee does not pay any taxes required to be withheld by the
Corporation or any of its Subsidiaries within ten days after a request for the
payment of such taxes, the Corporation or such Subsidiary may withhold such
taxes from any compensation to which the grantee is entitled.


                                   SECTION 11
                                   AMENDMENT

                  The right to alter and amend the Plan at any time to time and
the right to revoke or terminate the Plan are hereby specifically reserved to
the Board; provided that no such alteration or amendment of the Plan shall,
without stockholder approval, (i) increase the number of shares which may be
issued or delivered under the Plan as set forth in Section 3, (ii) increase the
maximum number of shares as to which stock options may be granted and as to
which shares may be awarded under the Plan to any one employee as set forth in
Section 4, (iii) make any changes in the class of employees eligible to receive
options or awards under the Plan or (iv) be made if stockholder approval of the
amendment is at the time required for grants or awards under the Plan to qualify
for the exemption from Section 16(b) of the 1934 Act provided by Rule 16b-3 or
by the rules of the New York Stock Exchange or any other stock exchange on which
the Common Stock may then be listed. No alteration, amendment, revocation or
termination of the Plan shall, without the written consent of the holder of an
outstanding grant or award under the Plan, adversely affect the rights of such
holder with respect to such outstanding grant or award.


                                   SECTION 12
                                  INTEGRATION

                  The Plan and any written agreements executed by employees and
the Corporation contain all of the understandings and representations between
the parties and supersede any prior understandings and agreements entered into
between them regarding the subject matter within. There are no representations,
agreements, arrangements or understandings, oral or written, between the parties
relating to the subject matter within which are not fully expressed in the Plan
and the agreements.


                                   SECTION 13
                      EFFECTIVE DATE AND DURATION OF PLAN

                  The effective date and date of adoption of the Plan shall be
January 24, 2000, the date of adoption of the Plan by the Board, and the
effective date of the amendments to the Plan adopted by the Board on March 22,
2000 shall be March 22, 2000, provided that such amendments are approved by
stockholders at a



                                       13

meeting duly called, convened and held on or prior to March 21, 2001, at which a
quorum representing a majority of the outstanding voting stock of the
Corporation is, either in person or by proxy, present and voting on the Plan. No
stock option or cash payment rights may be granted and no restricted shares or
performance units payable in performance shares may be awarded under the Plan
subsequent to January 23, 2010.

                 WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORPORATION

             1995 NON-EMPLOYEE DIRECTORS' FEE AND STOCK OPTION PLAN
                      (AS AMENDED THROUGH JANUARY 24, 2000)




                  The purposes of the 1995 Non-Employee Directors' Fee and Stock
Option Plan (as amended, the "Plan") are to provide for each director of
Westinghouse Air Brake Technologies Corporation (the "Company") who is not also
an employee of the Company or any of its subsidiaries (a "non-employee
Director") the payment of all or a portion of the retainer fees for future
services to be performed by such non-employee Director ("Director Fees") as a
member of the Board of Directors of the Company (the "Board") in shares of
Common Stock of the Company. The purposes of the Plan are further to promote the
long-term success of the Company by creating a long-term mutuality of interests
between the non-employee Directors and stockholders of the Company, to provide
an additional inducement for such non-employee Directors to remain with the
Company and to provide a means through which the Company may attract able
persons to serve as Directors of the Company.



                                    SECTION 1

                                 ADMINISTRATION



                  The Plan shall be administered by a Committee (the
"Committee") appointed by the Board of Directors of the Company (the "Board")
and consisting of not less than two members of the Board, each of whom at the
time of appointment to the Committee and at all times during service as a member
of the Committee shall be "Non-Employee Directors" as then defined under Rule
16b-3 under the Securities Exchange Act of 1934, as amended (the "1934 Act"), or
any successor Rule. The Committee shall keep records of action taken at its
meetings. A majority of the Committee shall constitute a quorum at any meeting,
and the acts of a majority of the members present at any meeting at which a
quorum is present, or acts approved in writing by all the members of the
Committee, shall be the acts of the Committee.



                  The Committee shall interpret the Plan and prescribe such
rules, regulations and procedures in connection with the operations of the Plan
as it shall deem to be necessary and advisable for the administration of the
Plan consistent with the purposes of the Plan. All questions of interpretation
and application of the Plan, or as to stock issued or delivered or stock options
granted under the Plan, shall be subject to the determination of the Committee,
which shall be final and binding.



                  Notwithstanding the above, the selection of the Directors to
whom stock may be issued or delivered for Director Fees or to whom stock options
are to be granted, the timing of such issuance or delivery or grants, the number
of shares subject to any issuance or delivery or stock option, the exercise
price of any stock option, the vesting or forfeiture of any stock option, the
periods during which any stock option may be



<PAGE>   2


exercised and the term of any stock option shall be as hereinafter provided, and
the Committee shall have no discretion as to such matters.



                                    SECTION 2

                         SHARES AVAILABLE UNDER THE PLAN



                  The aggregate number of shares which may be issued or
delivered and as to which grants of stock options may be made under the Plan is
500,000 shares of the Common Stock, par value $.01 per share, of the Company
(the "Common Stock"), subject to adjustment and substitution as set forth in
Section 6. If any stock option granted under the Plan is canceled by mutual
consent, is forfeited or terminates or expires for any reason without having
been exercised in full, the number of shares subject thereto shall again be
available for purposes of the Plan. The shares which may be issued or delivered
under the Plan may be either authorized but unissued shares or reacquired shares
or partly each, as shall be determined from time to time by the Board. If the
number of shares then remaining available, either for the payment of Directors
Fees through the use of shares as described in Section 3 below or for the grant
of stock options as described in Section 4 below, is not sufficient for each
non-employee Director entitled to receive the same to be issued or delivered the
number of shares or to be granted an option for the number of shares, as the
case may be, to which such non-employee Director is entitled (or the number of
adjusted or substituted shares pursuant to Section 6), then each non-employee
Director shall be issued or delivered a number of whole shares or granted an
option for a number of whole shares, as the case may be, equal to the number of
shares then remaining times a percentage obtained by dividing the number of
shares or option shares to which such non-employee Director is entitled by the
total number of shares or option shares to be granted to all non-employee
Directors at such time, disregarding any fractions of a share.

                            PAYMENT OF DIRECTOR FEES



                  Each non-employee Director shall automatically and without
further action by the Board or the Committee receive payment of Director Fees by
the issuance or delivery to the non-employee Director of 1,000 shares of Common
Stock, payable (i) on the first business day following the initial election of
such non-employee Director to the Board after the date of adoption of this Plan
by the Board, unless such first election occurs at an annual meeting of the
Company or within three months prior to the anniversary date of the prior year's
annual meeting, in which case payment of such Director Fees shall only occur
under subsection (ii) as hereinafter set forth and (iii) on the first business
day following the annual meeting of the stockholders of the Company to the
non-employee Directors as of that date.

                             GRANT OF STOCK OPTIONS



                  (a) On January 24, 2000, the date of the amendment to and
restatement of this Plan by the Board, each non-employee Director as of that
date shall automatically and without further action by the Board or the
Committee be granted (subject to the vesting provisions set forth in the next
succeeding sentence) a "nonstatutory stock option" (i.e., a stock option which
does not qualify under Sections 422 or 423 of the Internal Revenue Code of 1986
(the "Code")) to purchase 5,000 shares of Common Stock, subject to adjustment
and substitution as set forth in Section 6. Except as otherwise set forth in
section 5(E), the stock options granted under this Section 4(a) shall vest and
become exercisable as follows:

                  (i)      options with respect to 1,666 shares shall vest on
                           the first anniversary of the date of grant;



                  (ii)     options with respect to 1,667 shares shall vest on
                           the second anniversary of the date of grant; and



                  (iii)    options with respect to the final 1,667 shares shall
                           vest on the third anniversary of the date of grant.



                  (b) On the date of his or her first election to the Board
after January 24, 2000, each non-employee director shall automatically and
without further action by the Board or the Committee be granted a nonstatutory
stock option to purchase 5,000 shares of Common Stock, subject to adjustment and
substitution as set forth in Section 6. Except as otherwise set forth in section
5(E), the stock options granted under this Section 4(b) shall vest and become
exercisable as follows:

                  (i)      options with respect to 1,666 shares shall vest on
                           the first anniversary of the date of grant;



                  (ii)     options with respect to 1,667 shares shall vest on
                           the second anniversary of the date of grant; and



                  (iii)    options with respect to the final 1,667 shares shall
                           vest on the third anniversary of the date of grant.



                  (c) On the first business day of each calendar year each
non-employee Director as of that date shall automatically and without further
action by the Board or the Committee be granted a nonstatutory stock option to
purchase 2,000 shares of Common Stock, subject to adjustment and substitution as
set forth in Section 6. This new Section 4(c) shall replace in its entirety the
previous right of Directors to receive option grants to purchase 5,000 shares
every three years.

                                    SECTION 5

                      TERMS AND CONDITIONS OF STOCK OPTIONS



                  Stock options granted under the Plan shall be subject to the
following terms and conditions:



                  (A) The purchase price at which each stock option may be
         exercised (the "option price") shall be one hundred percent (100%) of
         the fair market value per share of the Common Stock on the date of the
         grant of such stock option pursuant to the Plan, determined as provided
         in Section 5(G); provided, however, that for any stock option granted
         under the Plan on or prior to October 31, 1998, the option price shall
         be the greater of the aforesaid amount or $14.00 per share.



                  (B) The option price for each stock option shall be paid in
         full upon exercise and shall be payable in cash in United States
         dollars (including check, bank draft or money order), which may include
         cash forwarded through a broker or other agent-sponsored exercise or
         financing program; provided, however, that in lieu of such cash the
         person exercising the stock option may pay the option price in whole or
         in part by delivering to the Company shares of the Common Stock having
         a fair market value on the date of exercise of the stock option,
         determined as provided in Section 5(G), equal to the option price for
         the shares being purchased; except that (i) any portion of the option
         price representing a fraction of a share shall in any event be paid in
         cash and (ii) no shares of the Common Stock which have been held for
         less than six months may be delivered in payment of the option price of
         a stock option. If the person exercising a stock option participates in
         a broker or other agent-sponsored exercise or financing program, the
         Company will cooperate with all reasonable procedures of the broker or
         other agent to permit participation by the person exercising the stock
         option in the exercise or financing program. Notwithstanding any
         procedure of the broker or other agent-sponsored exercise or financing
         program, if the option price is paid in cash, the exercise of the stock
         option shall not be deemed to occur and no shares of the Common Stock
         will be issued or delivered until the Company has received full payment
         in cash (including check, bank draft or money order) for the option
         price from the broker or other agent. The date of exercise of a stock
         option shall be determined under procedures established by the
         Committee, and as of the date of exercise the person exercising the
         stock option shall be considered for all purposes to be the owner of
         the shares with respect to which the stock option has been exercised.
         Payment of the option price with shares shall not increase the number
         of shares of the Common Stock which may be issued or delivered under
         the Plan as provided in Section 2.



                  (C) Subject to the terms of Section 5(E) providing for earlier
         or later termination of a stock option, no stock option shall be
         exercisable after the expiration of ten years from the date of grant. A
         stock option to the extent exercisable at any time may be exercised in
         whole or in part.



                  (D) No stock option shall be transferable by the grantee
         otherwise than by Will or, if the grantee dies intestate, by the laws
         of descent and distribution of the state of domicile of the grantee at
         the time of death. All stock options shall be exercisable during the
         lifetime of the grantee only by the grantee or the grantee's guardian
         or legal representative.



                  (E) If a grantee ceases to be a Director of the Company, any
         outstanding stock options held by the grantee shall vest and be
         exercisable and shall terminate, according to the following provisions:



                           (i) If a grantee ceases to be a non-employee Director
                  of the Company because he is removed without cause or because
                  his term lapses and he is not re-nominated for a new term, any
                  then outstanding stock option held by such grantee shall vest
                  and become exercisable in



                                       4
<PAGE>   5


                  accordance with the normal vesting schedule (including vesting
                  upon grant of an option) applicable to such option and shall
                  remain exercisable until the expiration date of such stock
                  option;



                           (ii) If during his term of office as a non-employee
                  Director a grantee is removed from office for cause, any then
                  outstanding stock option held by such grantee shall be
                  exercisable by the grantee (but only to the extent that such
                  stock option is vested and exercisable by the grantee
                  immediately prior to ceasing to be a non-employee Director) at
                  any time prior to the expiration date of such stock option or
                  within 90 days after the date of removal, whichever is the
                  shorter period;



                           (iii) Following the death of a grantee whether during
                  service as a non-employee Director of the Company or
                  thereafter, any outstanding stock option held by the grantee
                  at the time of death (whether or not vested and exercisable by
                  the grantee immediately prior to death) shall vest and be
                  exercisable by the person entitled to do so under the Will of
                  the grantee, or, if the grantee shall fail to make
                  testamentary disposition of the stock option or shall die
                  intestate, by the legal representative of the grantee at any
                  time prior to the expiration date of such stock option or
                  within one year after the date of death, whichever is the
                  longer period; and



                           (iv) If during his or her term of office as a
                  non-employee Director a grantee resigns from the Board during
                  his or her term or is nominated for re-election to the Board
                  but fails to win such re-election, any then outstanding stock
                  option held by such grantee shall be exercisable by the
                  grantee (but only to the extent that such stock option is
                  vested and exercisable by the grantee immediately prior to
                  ceasing to be a non-employee Director) at any time prior to
                  the expiration date of such stock option.



                  (F) All stock options shall be confirmed by an agreement, or
         an amendment thereto, which shall be executed on behalf of the Company
         by the Chief Executive Officer (if other than the President), the
         President or any Vice President and by the grantee.



                  (G) Fair market value of the Common Stock shall be the mean
         between the following prices, as applicable, for the date as of which
         fair market value is to be determined as quoted in The Wall Street
         Journal (or in such other reliable publication as the Committee, in its
         discretion, may determine to rely upon): (a) if the Common Stock is
         listed on the New York Stock Exchange, the highest and lowest sales
         prices per share of the Common Stock as quoted in the NYSE-Composite
         Transactions listing for such date, (b) if the Common Stock is not
         listed on such exchange, the highest and lowest sales prices per share
         of Common Stock for such date on (or on any composite index including)
         the principal United States securities exchange registered under the
         Securities Exchange Act of 1934 (the "1934 Act") on which the Common
         Stock is listed, or (c) if the Common Stock is not listed on any such
         exchange, the highest and lowest sales prices per share of the Common
         Stock for such date on the National Association of Securities Dealers
         Automated Quotations System or any successor system then in use
         ("NASDAQ"). If there are no such sale price quotations for the date as
         of which fair market value is to be determined but there are such sale
         price quotations within a reasonable period both before and after such
         date, then fair market value shall be determined by taking a weighted
         average of the means between the highest and lowest sales prices per
         share of the Common Stock as so quoted on the nearest date before and
         the nearest date after the date as of which fair market value is to be
         determined. The average should be weighted inversely by the respective
         numbers of trading days between the selling dates and the date as of


                                       5
<PAGE>   6


         which fair market value is to be determined. If there are no such sale
         price quotations on or within a reasonable period both before and after
         the date as of which fair market value is to be determined, then fair
         market value of the Common Stock shall be the mean between the bona
         fide bid and asked prices per share of Common Stock as so quoted for
         such date on NASDAQ, or if none, the weighted average of the means
         between such bona fide bid and asked prices on the nearest trading date
         before and the nearest trading date after the date as of which fair
         market value is to be determined, if both such dates are within a
         reasonable period. The average is to be determined in the manner
         described above in this Section 5(G). If the fair market value of the
         Common Stock cannot be determined on the basis previously set forth in
         this Section 5(G) for the date as of which fair market value is to be
         determined, the Committee shall in good faith determine the fair market
         value of the Common Stock on such date. Fair market value shall be
         determined without regard to any restriction other than a restriction
         which, by its terms, will never lapse.



                  (H) The obligation of the Company to issue or deliver shares
         of the Common Stock under the Plan shall be subject to (i) the
         effectiveness of a registration statement under the Securities Act of
         1933, as amended, with respect to such shares, if deemed necessary or
         appropriate by counsel for the Company, (ii) the condition that the
         shares shall have been listed (or authorized for listing upon official
         notice of issuance) upon each stock exchange, if any, on which the
         Common Stock shares may then be listed and (iii) all other applicable
         laws, regulations, rules and orders which may then be in effect.



                  Subject to the foregoing provisions of this Section 5 and the
other provisions of the Plan, any stock option granted under the Plan may be
subject to such restrictions and other terms and conditions, if any, as shall be
determined, in its discretion, by the Committee and set forth in the agreement
referred to in Section 5(F), or an amendment thereto.



                                    SECTION 6

                      ADJUSTMENT AND SUBSTITUTION OF SHARES



                  If a dividend or other distribution payable in shares of the
Common Stock shall be declared upon the Common Stock, each number of shares of
the Common Stock set forth in Sections 3 and 4, the number of shares of the
Common Stock then subject to any outstanding stock options and the number of
shares of the Common Stock which may be issued or delivered under the Plan but
are not then subject to outstanding stock options shall be adjusted by adding
thereto the number of shares of the Common Stock which would have been
distributable thereon if such shares had been outstanding on the date fixed for
determining the stockholders entitled to receive such stock dividend or
distribution.



                  If the outstanding shares of the Common Stock shall be changed
into or exchangeable for a different number or kind of shares of stock or other
securities of the Company or another corporation, whether through
reorganization, reclassification, recapitalization, stock split-up, combination
of shares, merger or consolidation, then there shall be substituted for each
share of the Common Stock set forth in Sections 3 and 4, for each share of the
Common Stock subject to any then outstanding stock option, and for each share of
the Common Stock which may be issued or delivered under the Plan but which is
not then subject to any outstanding stock option, the number and kind of shares
of stock or other securities into which each outstanding share of the Common
Stock shall be so changed or for which each such share shall be exchangeable.


                                       6
<PAGE>   7


                  In case of any adjustment or substitution as provided for in
this Section 6, the aggregate option price for all shares subject to each then
outstanding stock option prior to such adjustment or substitution shall be the
aggregate option price for all shares of stock or other securities (including
any fraction) to which such shares shall have been adjusted or which shall have
been substituted for such shares. Any new option price per share shall be
carried to at least three decimal places with the last decimal place rounded
upwards to the nearest whole number.



                  If the outstanding shares of Common Stock shall be changed in
value by reason of spin-off, split-off, or dividend in partial liquidation,
dividend in property other than cash or extraordinary distribution to holders of
the Common Stock, the Committee shall make any adjustments to any then
outstanding stock option which it determines are equitably required to prevent
dilution or enlargement of the rights of grantees which would otherwise result
from any such transaction.



                  No adjustment or substitution provided for in this Section 6
shall require the Company to issue or deliver or sell a fraction of a share or
other security. Accordingly, all fractional shares or other securities which
result from any such adjustment or substitution shall be eliminated and not
carried forward to any subsequent adjustment or substitution.



                  Except as provided in this Section 6, a grantee shall have no
rights by reason of any issue or delivery by the Company of stock of any class
or securities convertible into stock of any class, any subdivision or
consolidation of shares of stock of any class, the payment of any stock
dividends or any other increase or decrease in the number of shares of stock of
any class.



                                   SECTION 7

          EFFECT OF THE PLAN ON THE RIGHTS OF COMPANY AND STOCKHOLDERS



                  Nothing in the Plan, in any Director Fees paid or stock option
granted under the Plan, or in any stock option agreement shall confer any right
to any person to continue as a Director of the Company or interfere in any way
with the rights of the stockholders of the Company or the Board of Directors to
elect and remove Directors.

                                    SECTION 8

                            AMENDMENT AND TERMINATION



                  The right to amend the Plan at any time and from time to time
and the right to terminate the Plan at any time are hereby specifically reserved
to the Board; provided always that no such termination shall terminate any
outstanding stock options granted under the Plan; and provided further that no
amendment of the Plan shall (a) be made without stockholder approval if
stockholder approval of the amendment is at the time required for stock issued
or delivered for Director Fees or stock options under the Plan to qualify for
the exemption from Section 16(b) of the 1934 Act provided by Rule 16b-3 or by
the rules of the New York Stock Exchange or any other stock exchange on which
the Common Stock may then be listed, (b) amend more than once every six months
the provisions of the Plan relating to the selection of the Directors to whom
stock may be issued or delivered for Directors Fees or to whom stock options are
to be granted, the timing of such issuance or delivery or grants, the number of
shares subject to any issuance or delivery or stock option, the exercise price
of any stock option, the periods during which any stock option may be exercised
and the term of any stock option other than to comport with changes in the Code
or the rules and regulations thereunder or (c) otherwise amend the Plan in any
manner that would cause stock issued or delivered for Director Fees or stock
options under the Plan not to qualify for the exemption provided by Rule 16b-3.
No amendment or termination of the Plan shall, without the written consent of
the holder of a stock option theretofore awarded under the Plan, adversely
affect the rights of such holder with respect thereto.



                  Notwithstanding anything contained in the preceding paragraph
or any other provision of the Plan or any stock option agreement, the Board
shall have the power to amend the Plan in any manner deemed necessary or
advisable for stock issued or delivered for Director Fees or stock options
granted under the Plan to qualify for the exemption provided by Rule 16b-3 (or
any successor rule relating to exemption from Section 16(b) of the 1934 Act),
and any such amendment shall, to the extent deemed necessary or advisable by the
Board, be applicable to any outstanding stock options theretofore granted under
the Plan notwithstanding any contrary provisions contained in any stock option
agreement. In the event of any such amendment to the Plan, the holder of any
stock option outstanding under the Plan shall, upon request of the Committee and
as a condition to the exercisability of such option, execute a conforming
amendment in the form prescribed by the Committee to the stock option agreement
referred to in Section 5(F) within such reasonable time as the Committee shall
specify in such request.

                                  INTEGRATION



                  The Plan and any written agreements executed by the
non-employee Directors and the Company contain all of the understandings and
representations between the parties and supersede any prior understandings and
agreements entered into between them regarding the subject matter within. There
are no representations, agreements, arrangements or understandings, oral or
written, between the parties relating to the subject matter within which are not
fully expressed in the Plan and the agreements.



                                   SECTION 10

                  The effective date and date of adoption of the Plan shall be

of the Plan by the Board having been approved by the majority of the votes cast
at a meeting of the holders of voting stock of the Company) and the effective

shall be January 24, 2000. No stock may be issued or delivered for Director Fees
and no stock option may be granted under the Plan subsequent to October 31,

Re: Form 10-K Report for the year ended December 31, 1999.

Gentlemen:

This letter is written to meet the requirements of Regulation S-K calling
for a letter from a registrant's independent accountants whenever there has
been a change in accounting principle or practice.

As of January 1, 1999, certain of the Company's subsidiaries changed from
the LIFO method of accounting for inventory to the FIFO method. According
to the management of the Company, this change was made to better match
revenue and expense and to present inventory balances that more closely
reflect their current costs.

A complete coordinated set of financial and reporting standards for
determining the preferability of accounting principles among acceptable
alternative principles has not been established by the accounting
profession. Thus, we cannot make an objective determination of whether the
change in accounting described in the preceding paragraph is to a
preferable method. However, we have reviewed the pertinent factors,
including those related to financial reporting, in this particular case on
a subjective basis, and our opinion stated below is based on our
determination made in this manner.

We are of the opinion that the Company's change in method of accounting is
to an acceptable alternative method of accounting, which, based upon the
reasons stated for the change and our discussions with you, is also
preferable under the circumstances in this particular case. In arriving at
this opinion, we have relied on the business judgment and business planning
of your management.

Very truly yours,


/s/ Arthur Andersen LLP
