ITEM 1. BUSINESS

THE COMPANY

     Lennox International Inc. (including its subsidiaries, "Lennox" or the
"Company") is a leading global provider of climate control solutions. The
Company designs, manufactures and markets a broad range of products for the
heating, ventilation, air conditioning and refrigeration ("HVACR") markets. The
Company's products are sold under well-established brand names including
"Lennox", "Armstrong Air", "Ducane", "Bohn", "Larkin", "Heatcraft", "Advanced
Distributor Products" and others. The Company is also one of the largest
manufacturers in North America of heat transfer products, such as evaporator
coils and condenser coils. The Company has leveraged its expertise in heat
transfer technology, which is critical to the efficient operation of any heating
or cooling system, to become an industry leader known for its product innovation
and the quality and reliability of its products. The Company is also a leader in
the growing market for hearth products, which includes pre-fabricated fireplaces
and related products. Historically, the Company has sold its "Lennox" brand of
residential heating and air conditioning products directly to a network of
installing dealers, which currently numbers approximately 6,500, making it the
largest wholesale distributor of these products in North America. In September
1998, the Company initiated a program to acquire dealers in metropolitan areas
in the United States and Canada so that it can provide heating and air
conditioning products and services directly to consumers. The Company greatly
expanded this program with the acquisition of Service Experts, Inc. in January
2000, bringing the total of Company-owned dealerships to approximately 220.

     Shown below are the Company's four business segments, the key products and
brand names within each segment and 1999 net sales by segment. The North
American residential segment also includes installation, maintenance and repair
services performed by Company-owned dealers. Segment financial data for the
years 1997 through 1999, including financial information about foreign and
domestic operations, is included in Note 4 of the Notes to Consolidated
Financial Statements on pages 39 through 40 of the Company's 1999 Annual Report
to Stockholders.

</TABLE>

     The Company was founded in 1895 in Marshalltown, Iowa when Dave Lennox, who
owned a machine repair business for the railroads, successfully developed and
patented a riveted steel coal-fired furnace which was substantially more durable
than the cast iron furnaces used at the time. By 1904, the manufacture of these
furnaces had grown into a significant business and was diverting the Lennox
Machine Shop from its core business. As a result, in 1904, a group of investors
headed by D.W. Norris bought the furnace business and named it the Lennox
Furnace Company. Over the years, D.W. Norris ensured that ownership of the
Company

                                        1
<PAGE>   4

was distributed to all generations of his family, and currently approximately
sixty percent of the Company's ownership is broadly distributed among
approximately 110 descendants of or persons otherwise related to D.W. Norris. In
1991, the Company reincorporated as a Delaware corporation. On August 3, 1999,
the Company completed the initial public offering of its common stock.

     In 1999, the Company expanded its hearth products line through the
acquisition of Security Chimneys International, Ltd. In May 1999, the Company
acquired Livernois Engineering Holding Company and related patents. Livernois
produces heat transfer manufacturing equipment for the HVACR and automotive
industries. The Company acquired James N. Kirby Pty. Ltd., an Australian company
that participates in the commercial refrigeration and heat transfer markets in
Australia, in June 1999. In October 1999, the Company acquired substantially all
of the assets of the air conditioning and heating division of The Ducane
Company, Inc. based in South Carolina. This acquisition gives the Company
additional capacity to manufacture heating and air conditioning products. In
January 2000, the Company completed the acquisition of Service Experts, Inc. in
exchange for approximately 12.2 million shares of Lennox common stock and the
assumption of $160 million of debt. Service Experts provides residential
heating, ventilation and air conditioning ("HVAC") services and replacement
equipment through approximately 120 dealers in approximately 36 states. The
success of the Service Experts acquisition, along with the Company's other
acquisitions, will depend upon the Company's ability to integrate these
businesses into its business without substantial costs, delays or other
operational or financial difficulties. In addition, the operation of HVAC
dealers is a new line of business for the Company for which it has limited
experience.

  Forward Looking Statements

     This Annual Report on Form 10-K ("Form 10-K") contains forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended,
that are based upon management's beliefs, as well as assumptions made by and
information currently available to management. All statements other than
statements of historical fact included in this Form 10-K constitute
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995, including but not limited to statements
identified by the words "may," "will," "should," "plan," "predict,"
"anticipate," "believe," "intend," "estimate" and "expect" and similar
expressions. Such statements reflect the current views of Lennox with respect to
future events, based on what it believes are reasonable assumptions; however,
such statements are subject to certain risks, uncertainties and assumptions.
These include, but are not limited to, warranty and product liability claims;
the Company's ability to successfully complete and integrate acquisitions; the
Company's ability to manage new lines of business; the consolidation trend in
the HVACR industry; adverse reaction from the Company's customers from its
acquisitions or other activities; the impact of the weather on the Company's
business; competition in the HVACR business; increases in the prices of
components and raw materials; general economic conditions in the U.S. and
abroad; labor relations problems; operating risks; and environmental risks.
Should one or more of these risks or uncertainties materialize, or should
underlying assumptions prove incorrect, actual results may differ materially
from those in the forward-looking statements. The Company disclaims any
intention or obligation to update or review any forward-looking statements or
information, whether as a result of new information, future events or otherwise.

GROWTH STRATEGY

     The Company's growth strategy is designed to capitalize on its competitive
strengths in order to expand its market share and profitability in the worldwide
HVACR markets. The key elements of this strategy include:

  Expand Market in North America

     The Company's program to acquire heating and air conditioning dealers in
the United States and Canada represents a new direction for the heating and air
conditioning industry because, to its knowledge, no other major manufacturer has
made a significant investment in retail distribution. This strategy will enable
the Company to extend its distribution directly to the consumer, thereby
permitting it to participate in the
                                        2
<PAGE>   5

revenues and margins available at the retail level while strengthening and
protecting its brand equity. The Company believes that the retail sales and
service market represents a significant growth opportunity because this market
is large and highly fragmented. The retail sales and service market in the
United States is comprised of over 30,000 dealers. The Company started this
program in September 1998, and as of December 31, 1999, it had acquired 60
dealers in Canada and 33 in the United States for an aggregate purchase price of
approximately $241 million and had signed letters of intent to acquire 5
additional Canadian and 18 United States dealers for an aggregate purchase price
of approximately $59 million. The acquisition of Service Experts in January 2000
greatly accelerated this program by adding approximately 120 dealers in
approximately 36 states. The Company believes its long history of direct
relationships with its dealers through the one-step distribution system and the
resulting knowledge of local markets will give it advantages in identifying and
acquiring suitable candidates. The Company has assembled an experienced
management team to administer the dealer operations, and the Company has
developed a portfolio of training programs, management procedures and goods and
services that it believes will enhance the quality, effectiveness and
profitability of dealer operations.

     In addition to its acquisition program, the Company has initiated a program
to strengthen its independent dealer network by providing all dealers with a
broad array of services and support. Participants in the Company's associate
dealer program receive retirement and other benefits in exchange for agreeing
that at least 75% of their residential heating and air conditioning purchases
will be of the Company's products and for granting the Company a right of first
refusal to acquire their businesses. As of December 31, 1999, over 1,500 dealers
in the United States and Canada had joined the Company's associate dealer
program. All independent dealers, including participants in the associate dealer
program, are provided with access to the Company-sponsored volume purchasing
programs with third parties for goods and services used in their businesses.
Additionally, Contractors Success Group, a wholly owned subsidiary acquired in
January 2000 as part of the Service Experts acquisition, offers proprietary
products and marketing, management, educational and advisory services to dealers
(including Lennox-owned dealers) which are members of Contractors Success Group
in exchange for specified fees.

     The Company also intends to increase its market share in North America by:

     - selectively expanding its "Lennox" independent dealer network;

     - promoting the cross-selling of its "Armstrong Air," "Aire-Flo" and other
       residential heating and air conditioning brands to its existing network
       of "Lennox" dealers as a second line;

     - promoting the cross-selling of its hearth products to its "Lennox" dealer
       base;

     - expanding the geographic market for the "Armstrong Air" brand of
       residential heating and air conditioning products from its traditional
       presence in the Northeast and Central United States to the southern and
       western portions of the United States;

     - exploiting the fragmented third-party evaporator coil market; and

     - pursuing complementary acquisitions that expand its product offerings or
       geographic presence.

  Increase Presence in Hearth Products Market

     The Company manufactures and sells one of the broadest lines of hearth
products in North America, offering multiple brands of hearth products at a
range of price points. The Company believes that this broad product line will
allow it to compete successfully in the hearth products market since many
distributors prefer to concentrate their product purchases with a limited number
of suppliers. The Company believes that it can increase its penetration of this
market by selling in the traditional hearth products distribution channels and
through its historical HVAC distribution channels. Many of Lennox's heating and
air conditioning dealers have begun to expand their product offerings to include
hearth products.

                                        3
<PAGE>   6

  Exploit International Opportunities

     Worldwide demand for residential and commercial heating, air conditioning,
refrigeration and heat transfer products is increasing. The Company believes
that the increasing international demand for these products presents substantial
opportunities, especially in emerging markets and particularly for heat transfer
and refrigeration products. An example is the increasing use of refrigeration
products to preserve perishables including food products in underdeveloped
countries. Refrigeration products generally have the same design and
applications globally. To take advantage of international opportunities, the
Company has made substantial investments in manufacturing facilities in Europe,
Latin America and Asia Pacific through acquisitions, including James N. Kirby
Pty. Ltd. and a 70% interest in Ets. Brancher. The Company's international sales
have grown from $112.0 million in 1996 to $631.3 million in 1999. The Company
intends to continue to focus on expanding its international operations through
acquisitions and internal growth to take advantage of international growth
opportunities. The Company is also investing additional resources in its
international operations with the goal of achieving manufacturing and
distribution efficiencies comparable to that of its North American operations.

  Technology and Product Innovation

     An important part of Lennox's growth strategy is to continue to invest in
research and new product development. The Company has designated a number of its
facilities as "centers for excellence" that are responsible for the research and
development of core competencies vital to its success, such as combustion
technology, vapor compression, heat transfer and low temperature refrigeration.
Technological advances are disseminated from these "centers for excellence" to
all of Lennox's operating divisions.

PRODUCTS

  North American Residential Products and Services

     Heating and Air Conditioning Products. The Company manufactures and markets
a broad range of furnaces, heat pumps, air conditioners, packaged heating and
cooling systems and related products. These products are available in a variety
of product designs and efficiency levels at a range of price points intended to
provide a complete line of home comfort systems for both the residential
replacement and new construction markets. The Company markets these products
through multiple brand names. In addition, Lennox manufactures zoning controls,
thermostats and a complete line of replacement parts. The Company believes that
by maintaining a broad product line with multiple brand names, it can address
different market segments and penetrate multiple distribution channels.

     The Company's Advanced Distributor Products division builds evaporator
coils, unit heaters and air handlers under the "ADP" brand as well as the
"Lennox" and "Armstrong Air" brands. This division supplies the Company with
components for its heating and air conditioning products and produces evaporator
coils to be used in connection with competitors' heating and air conditioning
products and as an alternative to such competitors' brand name components. The
Company started this business in 1993 and has been able to achieve an
approximate 20% share of this market for evaporator coils through the
application of its technological and manufacturing skills.

     Hearth Products. The Company believes that it is the only North American
HVACR manufacturer that also designs, manufactures and markets residential
hearth products. The Company's hearth products include prefabricated gas and
wood burning fireplaces, free standing pellet and gas stoves, fireplace inserts,
gas logs and accessories. Many of the fireplaces are built with a blower or fan
option and are efficient heat sources as well as attractive amenities to the
home. The Company currently markets its hearth products under the "Lennox",
"Superior", "Marco", "Whitfield", "Earth Stove", and "Security Chimneys" brand
names. The Company believes that its strong relationship with its dealers and
its brand names will assist in selling into this market.

     Retail Service. Through Company-owned dealers in the United States and
Canada, the Company provides installation, maintenance, repair and replacement
services for heating and air conditioning systems

                                        4
<PAGE>   7

directly to both residential and light commercial customers. Installation
services include the installation of heating and air conditioning systems in new
construction and the replacement of existing systems. Other services include
preventative maintenance, emergency repairs and the replacement of parts
associated with heating and air conditioning systems. The Company also sells a
wide range of mechanical and electrical equipment, parts and supplies in
connection with these services.

  Commercial Air Conditioning

     The Company manufactures and sells commercial air conditioning equipment in
North America, Europe, Asia Pacific and South America.

     North America. In the North American commercial markets, the Company's air
conditioning equipment is used in applications such as low rise office
buildings, restaurants, retail and supermarket centers, churches and schools.
The Company's product offerings for these applications include rooftop units
which range from two to 30 tons of cooling capacity and split system/air handler
combinations which range from two to 20 tons. In North America, the Company
sells unitary equipment as opposed to larger applied systems. The Company's L
Series was introduced in 1995 and has been well received by the national
accounts market where it is sold to restaurants, mass merchandisers and other
retail outlets. The Company believes that this product's success is attributable
to its efficiency, design flexibility, low life cycle cost, ease of service and
advanced control technology.

     International. The Company competes in the commercial air conditioning
market in Europe through its ownership of 70% of Ets. Brancher and its operating
subsidiaries. The Company has agreed to buy the remaining 30% interest in Ets.
Brancher during the first half of 2000 for 102.5 million French francs, or
approximately $17 million. Lennox France manufactures and sells unitary products
which range from two to 30 tons and applied systems which range up to 500 tons.
Lennox's European products consist of chillers, air handlers, fan coils and
large rooftop units and serve medium rise buildings, shopping malls, other
retail and entertainment buildings, institutional applications and other field
engineered applications. Lennox manufactures its air conditioning products in
several locations throughout Europe, including sites in the United Kingdom,
France, Holland and Spain, and markets such products through various
distribution channels in these countries and in Italy, Germany, Belgium, the
Czech Republic, Eastern Europe and the Middle East.

     In Australia the Company distributes its residential and light commercial
heating and air conditioning products manufactured in North America and also
manufactures commercial heating and air conditioning products (packaged and
split systems) ranging in size from two to 60 tons.

     Through its 50% owned Fairco joint venture in Argentina, the Company
manufactures split system heating and air conditioning products and a limited
range of L Series commercial air conditioning products for sale in Argentina,
Chile and the surrounding Mercosur trading zone, which includes Brazil,
Argentina, Bolivia, Paraguay and Uruguay.

  Commercial Refrigeration

     North America. The Company is one of the leading manufacturers of
commercial refrigeration products in North America. The Company's refrigeration
products include chillers, condensing units, unit coolers, fluid coolers, air
cooled condensers and air handlers. The Company's refrigeration products are
sold for cold storage applications to preserve food and other perishables. These
products are used by supermarkets, convenience stores, restaurants, warehouses
and distribution centers. As part of its sale of commercial refrigeration
products, the Company routinely provides application engineering for consulting
engineers, contractors and others.

     International. Lennox manufactures and markets refrigeration products
through manufacturing facilities and joint ventures located in France, Italy and
Spain. The Company's refrigeration products include small chillers, unit
coolers, air cooled condensers, fluid coolers and refrigeration racks. These
products are sold to distributors, installing contractors and original equipment
manufacturers.

                                        5

     The Company also owns 50% of a joint venture in Mexico that produces unit
coolers and condensing units of the same design and quality as those
manufactured by the Company in the United States. Since this venture produces a
smaller range of products, the product line is complemented with imports from
the United States which are sold through the joint venture's distribution
network. Sales are made in Mexico to wholesalers, installing contractors and
original equipment manufacturers. As production volumes increase, there exists
the potential to export some of the high labor content products from the joint
venture into North America and Latin America.

     The Company owns an 84% interest in Heatcraft do Brasil S.A., a Brazilian
company that manufactures condensing units and unit coolers. The Company
believes this joint venture gives it the leading market share for commercial
refrigeration products in its served markets in Brazil.

     The Company acquired the assets of Lovelock Luke Pty. Limited, a
distributor of refrigeration and related equipment in Australia. This
acquisition gives the Company an established commercial refrigeration business
in Australia.

     In June 1999, the Company acquired James N. Kirby Pty. Ltd. for
approximately $65 million. Kirby is an Australian company that manufactures
commercial refrigeration and heat transfer products in Australia and distributes
commercial refrigeration equipment through its own and Lovelock's distribution
network. Kirby also designs and manufactures precision machining stations
primarily for the automobile industry. The Kirby acquisition provides a
technological and manufacturing base for the growth of the Company's commercial
refrigeration and heat transfer business in the Asia Pacific region.

  Heat Transfer

     The Company is one of the largest manufacturers of heat transfer
components, including coils, in the United States, Europe, Australia, Mexico and
Brazil. These products are used primarily by original equipment manufacturers of
residential and commercial air conditioning products, transportation air
conditioning and refrigeration systems, and commercial refrigeration products. A
portion of the Company's original equipment manufacturer coils are produced for
use in its residential and commercial HVACR products. The Company also produces
private label replacement coils for use in other manufacturers' HVACR equipment.
The Company believes that the engineering expertise of its sales force, combined
with its flexible manufacturing processes and systems, provide it with an
advantage in the application engineering, designing and manufacturing of these
products for its customers. Advanced computer software enables the Company to
predict with a high degree of accuracy the performance of complete air
conditioning and refrigeration systems.

     In addition to supplying the original equipment manufacturer market, the
Company also produces replacement coils for large commercial air conditioning,
heating and industrial processing systems. Many of these coils are specially
designed for particular systems and in the event of a failure may need to be
replaced quickly. The Company is the industry leader in this market and has
designed its manufacturing processes and systems in North America so that it can
deliver custom coils within 48 hours of receipt of an order. This premium
service enables the Company to receive superior prices and generate attractive
margins.

     The Company also designs and manufactures the equipment and tooling
necessary to produce coils. The Company uses such equipment and tooling in its
manufacturing facilities and sells it to third parties. Typically, there is a
long lead time between the initial order and receipt for this type of equipment
and tooling from third parties. Since the Company has the ability to quickly
produce the equipment and tooling necessary to manufacture heat transfer
products and systems, it can accelerate the international growth of its heat
transfer products segment. The Company also supplies heat transfer manufacturing
equipment to the automotive industry through Livernois.

     In addition to manufacturing heat transfer products in the North American
market, the Company produces coils in the Czech Republic for the European
market. The Company's joint venture in Mexico produces evaporator and condenser
coils for use in that country and for export to the Caribbean and the United
States. The Company's Brazilian joint venture manufactures heat transfer coils
that are sold to both HVACR manufacturers and automotive original equipment
manufacturers in Brazil.

MARKETING AND DISTRIBUTION

     The Company manages numerous distribution channels for its products in
order to better penetrate the HVACR market. Generally, the Company's products
are sold through a combination of distributors, independent and company-owned
dealers, wholesalers, manufacturers' representatives, original equipment
manufacturers and national accounts. The Company has also established separate
distribution networks in each country in which it conducts operations. The
Company deploys dedicated sales forces across all its business segments and
brands in a manner designed to maximize the ability of each sales force to
service its particular distribution channel. To maximize enterprise-wide
effectiveness, the Company has active cross-functional and cross-organizational
teams working on issues such as pricing and coordinated approaches to product
design and national account customers with interests cutting across business
segments.

     A principal example of the competitive strength of the Company's marketing
and distribution strategy is in the North American residential heating and air
conditioning market, in which it uses three distinctly different distribution
approaches -- the one-step distribution system, the two-step distribution system
and sales made directly to consumers through Company-owned dealers. The Company
markets and distributes its "Lennox" and "Aire-Flo" brands of heating and air
conditioning products directly to approximately 6,500 independent dealers that
install these products.

     The Company distributes its "Armstrong Air", "Air-Ease", "Concord,"
"Ducane" and "Magic-Pak" brands of residential heating and air conditioning
products through the traditional two-step distribution process whereby it sells
its products to distributors who, in turn, sell the products to a local
installing dealer. Accordingly, by using multiple brands and distribution
channels, the Company is able to better penetrate the North American residential
heating and air conditioning market. In addition, the Company has begun to
acquire or establish distributors in key strategic areas when a satisfactory
relationship with an independent distributor is not available.

     In addition, the Company provides heating and air conditioning products and
services directly to consumers through Company-owned dealers.

     Through the years, the "Lennox" brand has become synonymous with the "Dave
Lennox" image, which is utilized in national television and print advertising as
well as in numerous locally produced dealer ads, open houses and trade events,
and is easily the best recognized advertising icon in the heating and air
conditioning industry.

MANUFACTURING

     The Company operates 18 manufacturing facilities in the United States and
Canada and 21 outside the United States and Canada. These plants range from
small manufacturing facilities to large 1,000,000 square foot facilities in
Grenada, Mississippi and Marshalltown, Iowa. In its facilities most impacted by
seasonal demand, the Company manufactures both heating and air conditioning
products to smooth seasonal production demands and maintain a relatively stable
labor force. The Company is generally able to hire temporary employees to meet
changes in demand.

PURCHASING

     The Company relies on various suppliers to furnish the raw materials and
components used in the manufacture of its products. To maximize its buying power
in the marketplace, the Company utilizes a "purchasing council" that
consolidates purchases of its entire domestic requirements of particular items
across all business segments. The purchasing council generally concentrates its
purchases for a given material or component with one or two suppliers, although
the Company believes that there are alternative suppliers for all of its key raw
material and component needs. Compressors, motors and controls constitute the
Company's most significant component purchases, while steel, copper and aluminum
account for the bulk of the Company's raw material purchases. Although most of
the compressors used by the Company are purchased directly from major compressor
manufacturers, the Company owns a 24.5% interest in a joint venture to
manufacture compressors in the one and one-half to seven horsepower range. The
Company expects that this

                                        7
<PAGE>   10

joint venture, which began limited production in April 1998, will be capable of
providing the Company with a substantial portion of its compressor requirements
in the residential air conditioning market after achieving full production
levels, which is expected in 2001.

     The Company attempts to minimize the risk of price fluctuations in key
components by entering into contracts, typically at the beginning of the year,
which generally provide for fixed prices for its needs throughout the year. In
instances where the Company is unable to pass on to its customers increases in
the costs of copper and aluminum, the Company enters into forward contracts for
the purchase of such materials. Increases in the prices of raw materials or
components or problems in their availability could depress the Company's sales
or increase the costs of the Company's products.

INFORMATION SYSTEMS

     The Company's North American operations are supported by enterprise
business systems which support all core business processes. Enterprise business
systems are designed to enhance the continuity of operations, ensure appropriate
controls, and support timely and efficient decision making. The Company's two
largest operating divisions, Lennox Industries and Heatcraft, have installed the
SAP enterprise business software system. A version of ROI Manage 2000 was
implemented for Armstrong.

TECHNOLOGY AND RESEARCH AND DEVELOPMENT

     The Company supports an extensive research and development program focusing
on the development of new products and improvements to its existing product
lines. The Company spent an aggregate of $39.1 million, $33.3 million and $25.4
million on research and development during 1999, 1998 and 1997, respectively. As
of December 31, 1999, the Company employed approximately 440 persons dedicated
to research and development activities. The Company has a number of research and
development facilities located around the world, including a limited number of
"centers for excellence" that are responsible for the research and development
of particular core competencies vital to its business, such as combustion
technology, vapor compression, heat transfer and low temperature refrigeration.

     The Company uses advanced, commercially available computer-aided design,
computer-aided manufacturing, computational fluid dynamics and other
sophisticated software not only to streamline the design and manufacturing
processes, but also to give it the ability to run complex computer simulations
on a product design before a working prototype is created. The Company operates
a full line of metalworking equipment and advanced laboratories certified by
applicable industry associations.

PATENTS AND TRADEMARKS

     The Company holds numerous patents that relate to the design and use of its
products. The Company considers these patents important, but no single patent is
material to the overall conduct of its business. The Company's policy is to
obtain and protect patents whenever such action would be beneficial to it. No
patent which the Company considers material will expire in the next five years.
The Company owns several trademarks that it considers important in the marketing
of its products, including Lennox(R), Heatcraft(R), CompleteHeat(R), Raised
Lance(TM), Larkin(TM), Climate Control(TM), Chandler Refrigeration(R), Bohn(R),
Advanced Distributor Products(R), Armstrong Air(TM), Aire-Flo(TM), Air-Ease(R),
Concord(R), Magic-Pak(R), Superior(TM), Marco(R), Whitfield(R), Security
Chimneys(R), Janka(TM), Alcair(TM), Ducane(TM) and Friga-Bohn(TM). These
trademarks have no fixed expiration dates and the Company believes its rights in
these trademarks are adequately protected.

COMPETITION

     Substantially all of the markets in which the Company participates are
highly competitive. The most significant competitive factors facing the Company
are product reliability, product performance, service and price, with the
relative importance of these factors varying among its product lines. In
addition, the Company faces competition from independent dealers and dealers
owned by consolidators and utility companies. The Company's competitors may have
greater financial and marketing resources than it has. Listed below are some

                                        8

EMPLOYEES

     As of March 1, 2000, the Company employed approximately 22,650 employees,
approximately 3,950 of which were represented by unions. The number of hourly
workers the Company employs during the course of the year may vary in order to
match its labor needs during periods of fluctuating demand. The Company believes
that its relationships with its employees are generally good.

     Within the United States, the Company has eight manufacturing facilities
and five distribution centers, along with its North American Parts Center in Des
Moines, Iowa, with collective bargaining agreements ranging from three to eight
years in length. The five distribution centers are covered by a single contract
that expires in 2001. Two collective bargaining agreements expire in
2000 -- Burlington, Washington and Atlanta, Georgia -- and three expire in
2002 -- Bellevue, Ohio, Danville, Illinois and Union City, Tennessee. Outside of
the United States, the Company has 13 significant facilities that are
represented by unions. The four agreements for Lennox France have no fixed
expiration date. The agreement at the Company's facility in Burgos, Spain
expires in 2000, the agreement at its facility in Toronto, Ontario expires in
2001, and the agreement at its facility in Laval, Quebec expires in 2002. The
Company believes that its relationships with the unions representing its
employees are generally good, and does not anticipate any material adverse
consequences resulting from negotiations to renew these agreements.

REGULATION

     The Company's operations are subject to evolving and often increasingly
stringent federal, state, local and international laws and regulations
concerning the environment. Environmental laws that affect or could affect the
Company's domestic operations include, among others, the Clean Air Act, the
Clean Water Act, the Resource Conservation and Recovery Act, the Comprehensive
Environmental Response, Compensation, and Liability Act, the Occupational Safety
and Health Act, the National Environmental Policy Act, the Toxic Substances
Control Act, any regulations promulgated under these acts and various other
Federal, state and local laws and regulations governing environmental matters.
The Company believes it is in substantial compliance with such existing
environmental laws and regulations. The Company's non-United States operations
are also subject to various environmental statutes and regulations. Generally,
these statutes and regulations impose operational requirements that are similar
to those imposed in the United States. The Company believes it is in substantial
compliance with applicable non-United States environmental statutes and
regulations.

     Refrigerants. In the past decade, there has been increasing regulatory and
political pressure to phase out the use of certain ozone depleting substances,
including hydrochlorofluorocarbons, which are sometimes referred to as "HCFCs".
This development is of particular importance to the Company and its competitors
because of the common usage of HCFCs as refrigerants for air conditioning and
refrigeration equipment. As discussed below, the Company does not believe that
implementation of the phase out schedule for HCFCs contained in the current
regulations will have a material adverse effect on its financial position or
results of operations. The Company does believe, however, that there will likely
be continued pressure by the
                                        9
<PAGE>   12

international environmental community for the United States and other countries
to accelerate the phase out schedule. The Company has been an active participant
in the ongoing international dialogue on these issues and believes that it is
well positioned to react to any changes in the regulatory landscape.

     In September 1987, the United States became a signatory to an international
agreement titled the Montreal Protocol on Substances that Deplete the Ozone
Layer. The Montreal Protocol requires its signatories to phase out HCFCs on an
orderly basis. All countries in the developed world have become signatories to
the Montreal Protocol. The manner in which these countries implement the
Montreal Protocol and regulate HCFCs differs widely.

     The 1990 U.S. Clean Air Act amendments implement the Montreal Protocol by
establishing a program to limit the production, importation and use of specified
ozone depleting substances, including HCFCs currently used as refrigerants by
the Company and its competitors. Under the Clean Air Act and implementing
regulations, all HCFCs must be phased out between 2010 and 2030. The Company
believes that these regulations as currently in effect will not have a material
adverse effect on its operations. Nonetheless, as the supply of virgin and
recycled HCFCs falls, it will be necessary to address the need to substitute
permitted substances for HCFCs. Further, the United States is under pressure
from the international environmental community to accelerate the current 2030
deadline for phase out of HCFCs. An accelerated phase out schedule could
adversely affect the Company's future financial results and the industry
generally.

     The Company, together with major chemical manufacturers, are continually in
the process of reviewing and addressing the potential impact of refrigerant
regulations on its products. The Company believes that the combination of
products that presently utilize HCFCs, and products in the field which can be
retrofitted to alternate refrigerants, provide a complete line of commercial and
industrial products. Therefore, the Company does not foresee any material
adverse impact on its business or competitive position as a result of the
Montreal Protocol, the 1990 Clean Air Act amendments or their implementing
regulations. However, the Company believes that the implementation of severe
restrictions on the production, importation or use of refrigerants the Company
employs in larger quantities or acceleration of the current phase out schedule
could have such an impact on the Company and its competitors.

     The Company is subject to appliance efficiency regulations promulgated
under the National Appliance Energy Conservation Act of 1987, as amended, and
various state regulations concerning the energy efficiency of its products. The
Company has developed and is developing products which comply with National
Appliance Energy Conservation Act regulations, and does not believe that such
regulations will have a material adverse effect on its business. The United
States Department of Energy began in 1998 its review of national standards for
comfort products covered under National Appliance Energy Conservation Act. It is
anticipated that the National Appliance Energy Conservation Act regulations
requiring manufacturers to phase in new higher efficiency products will not take
effect prior to 2006. The Company believes it is well positioned to comply with
any new standards that may be promulgated by the Department of Energy and does
not foresee any adverse material impact from a National Appliance Energy
Conservation Act standard change.

     Remediation Activity. In addition to affecting the Company's ongoing
operations, applicable environmental laws can impose obligations to remediate
hazardous substances at its properties, at properties formerly owned or operated
by the Company and at facilities to which it sent or sends waste for treatment
or disposal.

     The Company's Grenada facility is subject to an administrative order issued
by the Mississippi Department of Environmental Quality under which the Company
will conduct groundwater remediation. The Company has established a $1.7 million
reserve to cover costs of remediation at the Grenada facility and possible costs
associated with remediation activities at the Company's Danville facility. The
Company is aware of contamination at some of its other facilities, however, the
Company does not believe that future remediation costs, if any, at such
facilities will be material.

     During environmental due diligence for a plant the Company acquired in 1999
in Blackville, South Carolina, the Company learned of soil and groundwater
contamination at the site which requires further assessment and possible
remediation. These projects are being conducted and funded by the prior owner of
the

                                       10
<PAGE>   13

facility, under contractual obligations pursuant to which the Company acquired
the facility. The Company has no reason to believe that the prior owner will not
continue to conduct and pay for the required assessments and remediation.
However, if the prior owner refuses to meet its contractual obligations, the
Company would be required to complete the remediation. The prior owner of the
Blackville site has provided a letter of credit in the amount of $700,000 to
secure its obligations for assessment and remediation.

     From time to time the Company has received notices that it is a potentially
responsible party along with other potentially responsible parties in Superfund
proceedings for cleanup of hazardous substances at certain sites to which the
potentially responsible parties are alleged to have sent waste. Based on the
facts presently known, the Company does not believe that environmental cleanup
costs associated with any Superfund sites where the Company has received notice
that it is a potentially responsible party will have a material adverse effect
on its financial position or results of operations.

     Dealer operations. The heating and air conditioning dealers acquired in the
United States and Canada will be subject to various federal, state and local
laws and regulations, including:

     - permitting and licensing requirements applicable to service technicians
       in their respective trades;

     - building, heating, ventilation, air conditioning, plumbing and electrical
       codes and zoning ordinances;

     - laws and regulations relating to consumer protection, including laws and
       regulations governing service contracts for residential services; and

     - laws and regulations relating to worker safety and protection of the
       environment.

     A large number of state and local regulations governing the residential and
commercial maintenance services trades require various permits and licenses to
be held by individuals. In some cases, a required permit or license held by a
single individual may be sufficient to authorize specified activities for all of
the Company's service technicians who work in the geographic area covered by the
permit or license.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
                        ON FINANCIAL STATEMENT SCHEDULE

To: The Stockholders and Board of Directors of Lennox International Inc.

     We have audited in accordance with generally accepted auditing standards
the consolidated financial statements of Lennox International Inc. and
subsidiaries included in this Annual Report on Form 10-K and have issued our
report thereon dated February 18, 2000. Our audits were made for the purpose of
forming an opinion on the basic consolidated financial statements taken as a
whole. Schedule II, Valuation and Qualifying Accounts and Reserves, 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 consolidated financial statements. This schedule has been subjected to
the auditing procedures applied in the audits of the basic consolidated
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
consolidated statements taken as a whole.

                                   THE CREDITS

         SECTION 2.01. Commitments. Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Lender
agrees, severally and not jointly, to make advances (each such advance a "Loan")
to the Borrower, at any time and from time to time on and after the date hereof
and until the earlier of the Maturity Date or the termination of the Commitment
of such Lender, in an aggregate principal amount at any time outstanding not to
exceed such Lender's Commitment, subject, however, to the condition that the
Revolving Exposure of a Lender shall not exceed such Lender's Commitment and the
total Revolving Exposures of all Lenders shall not exceed the Total Commitment.
Within the foregoing limits, the Borrower may borrow, pay or prepay and reborrow
Loans hereunder, on and after the Effective Date and prior to the Maturity Date,
subject to the terms, conditions and limitations set forth herein.

         SECTION 2.02. Loans.

         (a) Each Loan shall be made as part of a Borrowing consisting of Loans
made by the Lenders ratably in accordance with their Applicable Percentages;
provided, however, that the failure of any Lender to make any Loan shall not in
itself relieve any other Lender of its obligation to lend hereunder (it being
understood, however, that no Lender shall be responsible for the failure of any
other Lender to make any Loan required to be made by such other Lender). The
Loans comprising any Borrowing shall be in an aggregate principal amount which
is an integral multiple of $1,000,000 and not less than $5,000,000 (or an
aggregate principal amount equal to the remaining balance of the Total
Commitment less the total Revolving Exposures of all Lenders).

         (b) Each Borrowing (including any Borrowing of a Swingline Loan) shall
be comprised entirely of Eurodollar Loans or ABR Loans or, with respect to
Swingline Loans only, Swingline Loans accruing interest at the Negotiated Rate,
as the Borrower may request pursuant to Section 2.03 or, with respect to
Swingline Loans, Section 2.19(a). Each Lender may at its option make any
Eurodollar Loan by causing any


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 13


<PAGE>   18
domestic or foreign branch or Affiliate of such Lender to make such Eurodollar
Loan; provided that any exercise of such option shall not affect the obligation
of the Borrower to repay such Eurodollar Loan in accordance with the terms of
this Agreement. Borrowings of more than one Type may be outstanding at the same
time.

         (c) Subject to paragraph (d) below, each Lender shall make each Loan to
be made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds to the Administrative Agent in New York, New York,
not later than 11:00 a.m., New York, New York time, and the Administrative Agent
shall by 2:00 p.m., New York, New York time, credit the amounts so received to
the account or accounts specified from time to time in one or more notices
delivered by the Borrower to the Administrative Agent or, if a Borrowing shall
not occur on such date because any condition precedent herein specified shall
not have been met, return the amounts so received to the respective Lenders or,
if such Borrowing is to finance the reimbursement of an LC Disbursement, such
amounts shall be distributed to the Issuing Bank. Loans shall be made by the
Lenders pro rata in accordance with Section 2.13. Unless the Administrative
Agent shall have received notice from a Lender prior to the date of any
Borrowing that such Lender will not make available to the Administrative Agent
such Lender's portion of such Borrowing, the Administrative Agent may assume
that such Lender has made such portion available to the Administrative Agent on
the date of such Borrowing in accordance with this paragraph (c) and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower on such date a corresponding amount. If and to the extent that such
Lender shall not have made such portion available to the Administrative Agent,
such Lender and the Borrower (without waiving any claim against such Lender for
such Lender's failure to make such portion available) severally agree to repay
to the Administrative Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the
Administrative Agent at (i) in the case of the Borrower, the interest rate
applicable at the time to the Loans comprising such Borrowing and (ii) in the
case of such Lender, the Federal Funds Effective Rate. If such Lender shall
repay to the Administrative Agent such corresponding amount, such amount shall
constitute such Lender's Loan as part of such Borrowing for purposes of this
Agreement.

         (d) Borrower may Convert all or any part of any Borrowing (excluding a
Borrowing comprised of a Swingline Loan) to a Borrowing of a different Type and
Borrower may Continue all or any part of any Eurodollar Borrowing (excluding a
Borrowing comprised of a Swingline Loan) as a Borrowing of the same Type, by
giving the Administrative Agent written notice on the Business Day of the
Conversion into an ABR Borrowing and on the Business Day at least three Business
Days before Conversion into or Continuation of a Eurodollar Borrowing
specifying: (i) the Conversion or Continuation date, (ii) the amount of the
Borrowing to be Converted or Continued, (iii) in the case of Conversions, the
Type of Borrowing to be Converted into, and (iv) in the case of a Continuation
of or Conversion into a Eurodollar Borrowing, the duration of the Interest
Period applicable thereto; provided that (a) Eurodollar Borrowings may only be
Converted on the last day of the Interest Period; (b) except for Conversions to
ABR Borrowings, no Conversions shall be made while an Event of Default has
occurred and is continuing; (c) only ten (10) Eurodollar Borrowings (including
Eurodollar Borrowings of Swingline Loans) may be in existence at any one time;
and (d) no Interest Period may end after the Maturity Date. All notices given
under this Section shall be irrevocable and shall be given not later than 11:00
a.m. New York, New York time on the Business Day which is not less than the
number of Business Days specified above for such notice. If the Borrower shall
fail to give the Agent the notice as specified above for Continuation or
Conversion of a Eurodollar Borrowing (excluding a Borrowing of a Swingline Loan)
prior to the end of the Interest Period with respect thereto, such Eurodollar
Borrowing shall automatically be continued as a Eurodollar Borrowing with an
Interest Period of one month's duration unless any Event of Default exists in
which case such Eurodollar Borrowing shall be automatically converted to an ABR
Borrowing. The Agent shall promptly advise the Lenders of any notice given
pursuant to this Section 2.02.


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 14


<PAGE>   19
         SECTION 2.03. Borrowing Procedure. In order to request a Borrowing
(other than a Swingline Loan), the Borrower shall hand deliver or telecopy to
the Administrative Agent a duly completed Borrowing Request (a) in the case of a
Eurodollar Borrowing, not later than 11:00 a.m., New York, New York time, three
Business Days before such Borrowing and (b) in the case of an ABR Borrowing, not
later than 11:00 a.m., New York, New York time, on the day of such Borrowing.
Such notice shall be irrevocable and shall in each case specify: (i) whether the
Borrowing then being requested is to be a Eurodollar Borrowing or an ABR
Borrowing; (ii) the date of such Borrowing (which shall be a Business Day) and
the amount thereof; and (iii) if such Borrowing is to be a Eurodollar Borrowing,
the Interest Period with respect thereto, which shall not end after the Maturity
Date. If no election as to the Type of Borrowing is specified in any such
notice, then the requested Borrowing shall be an ABR Borrowing. If no Interest
Period with respect to any Eurodollar Borrowing is specified in any such notice,
then the Borrower shall be deemed to have selected an Interest Period of one
month's duration. Notwithstanding any other provision of this Agreement to the
contrary, no Borrowing shall be requested if the Interest Period with respect
thereto would end after the Maturity Date. The Administrative Agent shall
promptly advise the Lenders of any notice given pursuant to this Section 2.03
and of each Lender's portion of the requested Borrowing.

         SECTION 2.04. Fees.

         (a) The Borrower agrees to pay to each Lender, through the
Administrative Agent, on each March 31, June 30, September 30 and December 31
(with the first payment being due on March 31, 2000) and on each date on which
the Commitment of such Lender shall be terminated as provided herein, a
commitment fee (a "Commitment Fee"), at a rate per annum equal to the Commitment
Fee Percentage from time to time in effect on the amount of the daily average of
the unused Commitment of such Lender, during the preceding quarter (or other
period commencing on the Effective Date or ending with the Maturity Date or any
date on which the Commitment of such Lender shall be terminated). All Commitment
Fees shall be computed on the basis of the actual number of days elapsed in a
year of 365 or 366 days, as the case may be. The Commitment Fee due to each
Lender shall commence to accrue on the Effective Date, and shall cease to accrue
on the earlier of the Maturity Date or the termination of the Commitment of such
Lender as provided herein. A Lender's Commitment (other than the Swingline
Lender) shall be deemed used by the aggregate amount of all Loans made by the
Lender and such Lender's Applicable Percentage of the Letter of Credit
Liabilities. Swingline Loans are not a use for purposes of calculating the
Commitment Fee for any Lender other than the Swingline Lender. The Swingline
Lender's Commitment shall be deemed used by the aggregate amount of all Loans
and Swingline Loans made by the Swingline Lender and the Swingline Lender's
Applicable Percentage of the Letter of Credit Liabilities.

         (b) The Borrower agrees to pay the Administrative Agent the fees
provided for in the Fee Letter on the dates required thereby (the
"Administrative Fees").

         (c) The Borrower agrees to pay (i) to the Administrative Agent for the
account of each Lender a participation fee with respect to its participations in
Letters of Credit, which shall accrue at the rate equal to the Applicable Margin
on the average daily amount of such Lender's Applicable Percentage of the Letter
of Credit Liabilities (excluding any portion thereof attributable to
unreimbursed LC Disbursements) during the period from and including the
Effective Date to but excluding the later of the date on which such Lender's
Commitment terminates and the date on which such Lender ceases to have any
Letter of Credit Liabilities, and (ii) to the Issuing Bank a fronting fee, which
shall accrue at the rate of 0.125% per annum on the average daily amount of the
Letter of Credit Liabilities (excluding any portion thereof attributable to
unreimbursed LC Disbursements) during the period from and including the
Effective Date to but excluding the later of the date of termination of the
Commitments and the date on which there ceases to be any Letter of Credit
Liabilities, as well as the Issuing Bank's standard fees with respect to the
issuance, amendment, renewal


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 15


<PAGE>   20

or extension of any Letter of Credit or processing of drawings thereunder.
Participation fees and fronting fees accrued through and including each Interest
Payment Date shall be payable on the third Business Day following such Interest
Payment Date, commencing on the first such date to occur after the Effective
Date; provided that all such fees shall be payable on the date on which the
Commitments terminate and any such fees accruing after the date on which the
Commitments terminate shall be payable on demand. Any other fees payable to the
Issuing Bank pursuant to this paragraph shall be payable within 10 days after
demand. All participation fees and fronting fee shall be computed on the basis
of a year of 360 days and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day).

         (d) The Fees shall be paid on the dates due, in immediately available
funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees
payable to it) for distribution, if and as appropriate, among the Lenders. Once
paid, none of such Fees shall be refundable under any circumstances.

         SECTION 2.05. Repayment of Borrowings; Evidence of Indebtedness.

         (a) The Borrower hereby unconditionally promises to pay (i) the then
unpaid principal amount of each Loan on the Maturity Date and (ii) the then
unpaid principal amount of each Swingline Loan on the earlier of (A) the
Maturity Date or (B) the later of the first date after such Swingline Loan is
made that is the 15th or last day of a calendar month and is at least two
Business Days after such Swingline Loan is made or, in the case of each
Swingline Loan which is a Eurodollar Borrowing or a Negotiated Rate Borrowing,
the last day of the Interest Period with respect thereto; provided that on each
date that a Loan is made, the Borrower shall repay all Swingline Loans then
outstanding which are ABR Loans. Payments under this Section 2.05 shall be made
to the Administrative Agent for the account of the Lenders except payments made
in respect of Swingline Loans in which no participations have been purchased
shall be made to the Swingline Lender. Following receipt by the Administrative
Agent of any payment from the Borrower pursuant to this paragraph, the
Administrative Agent shall distribute such payment to the Lenders as their
interests may appear in accordance with Section 2.18.

         (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness to such Lender resulting from
each Loan or Swingline Loan made by such Lender from time to time, including the
amounts of principal and interest payable and paid to such Lender from time to
time under this Agreement.

         (c) The Administrative Agent shall maintain accounts in which it will
record (i) the amount of each Borrowing hereunder, the Type of each Borrowing
made and the Interest Period applicable thereto, if any, (ii) the amount of any
principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder in respect of Borrowings and (iii) the amount
of any sum received by the Administrative Agent hereunder from the Borrower and
each Lender's share thereof.

         (d) The entries made in the accounts maintained pursuant to paragraphs
(b) and (c) of this Section 2.05 shall, to the extent permitted by applicable
law, be prima facie evidence of the existence and amounts of the obligations
therein recorded; provided, however, that the failure of any Lender or the
Administrative Agent to maintain such accounts or any error therein or an
inconsistency between such accounts of a Lender and the accounts of the
Administrative Agent shall not in any manner affect the obligations of the
Borrower to repay the Borrowings in accordance with their terms.

Borrowing plus the Applicable Margin from time to time in effect. Subject to the
provisions of Section 2.07, the Swingline Loans comprising each Negotiated Rate
Borrowing shall bear interest (computed on the basis of the actual number of

may be, for periods during which the Alternate Base Rate is determined by
reference to the Prime Rate and 360 days for other periods and including for all
calculations the first day of any period but excluding the last) at a rate per
annum equal to the Alternate Base Rate.

         (c) Interest on each Loan and Swingline Loan shall be payable on each
Interest Payment Date applicable to such Loan or Swingline Loan except as
otherwise provided in this Agreement. The applicable LIBO Rate or Alternate Base
Rate shall be determined by the Administrative Agent, and such determination
shall be conclusive absent manifest error; provided that the Administrative
Agent shall, upon request, provide to the Borrower a certificate setting forth
in reasonable detail the basis for such determination.

         (d) The Applicable Margin identified in this Section 2.06 and the
Commitment Fee Percentage identified in Section 2.04 shall be defined and
determined as follows:

                           "Applicable Margin" shall mean (i) during the period
                  commencing on the Effective Date and ending on but not
                  including the first Adjustment Date (as defined below), 1.125%
                  per annum and (ii) during each period from and including one

         Upon delivery of the Compliance Certificate pursuant to Section 5.20(g)
in connection with the financial statements of the Borrower and its Subsidiaries
required to be delivered pursuant to Sections 5.20(a) and (b), commencing with
such Compliance Certificate delivered with respect to the fiscal quarter ending
on March 31, 2000, the Applicable Margin (for Interest Periods commencing after
the applicable Adjustment Date) and the Commitment Fee Percentage shall
automatically be adjusted in accordance with the Debt to Adjusted EBITDA Ratio
set forth therein and the table set forth above, such automatic adjustment to
take effect as of the first Business Day after the receipt by the Agent of the
related Compliance Certificate pursuant to Section 5.20(g) (each such Business
Day when such margin or fees change pursuant to this sentence or the next
following sentence, herein an "Adjustment Date"). If the Borrower fails to
deliver such Compliance Certificate which so sets forth the Debt to Adjusted
EBITDA Ratio within the period of time required by Section 5.20(g): (i) the
Applicable Margin (for Interest Periods commencing after the applicable
Adjustment Date) shall automatically be adjusted to 1.25% per annum; and (ii)
the Commitment Fee Percentage shall automatically be adjusted to 0.300% per
annum, such automatic adjustments to take effect as of the first Business Day
after the last day on which the Borrower was required to deliver the applicable
Compliance Certificate in accordance with Section 5.20(g) and to remain in
effect until subsequently adjusted in accordance herewith upon the delivery of a
Compliance Certificate.

         SECTION 2.07. Default Interest. If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder, whether by scheduled maturity, notice of prepayment, acceleration
or otherwise, the Borrower shall on demand from time to time from the
Administrative Agent pay interest, to the extent permitted by law, on such
defaulted amount up to (but not including) the date of actual payment (after as
well as before judgment) at a rate per annum (computed as provided in Section
2.06(b)) equal to the Alternate Base Rate plus 2%.

         SECTION 2.08. Alternate Rate of Interest. In the event, and on each
occasion, that prior to the commencement of any Interest Period for a Eurodollar
Borrowing the Administrative Agent shall have determined (i) that dollar
deposits in the principal amounts of the Eurodollar Loans comprising such
Borrowing are not generally available in the London interbank market or (ii)
that reasonable means do not exist for ascertaining the LIBO Rate, the
Administrative Agent shall, as soon as practicable thereafter, give telecopy
notice of such determination to the Borrower and the Lenders. In the event of
any such determination under clauses (i) or (ii) above, until the Administrative
Agent shall have advised the Borrower and the Lenders that the circumstances
giving rise to such notice no longer exist, any request by the Borrower for a
Eurodollar Borrowing pursuant to Section 2.03 shall be deemed to be a request
for an ABR Borrowing. In the event the Required Lenders notify the
Administrative Agent that the rates at which dollar deposits are being offered
will not adequately and fairly reflect the cost to such Lenders of making or
maintaining Eurodollar Loans during such Interest Period, the Administrative
Agent shall notify the Borrower of such notice and until the Required Lenders
shall have advised the Administrative Agent that the circumstances giving rise
to such notice no longer exist, any request by the Borrower for a Eurodollar
Borrowing shall be deemed a request for an ABR Borrowing. Each determination by
the Administrative Agent hereunder shall be made in good faith and shall be
conclusive absent manifest error; provided that the Administrative Agent, shall,
upon request, provide to the Borrower a certificate setting forth in reasonable
detail the basis for such determination.

         SECTION 2.09. Termination and Reduction of Commitments.

         (a) The commitment of the Swingline Lender under Section 2.19 to make
Swingline Loans, the commitment of the Issuing Bank to issue Letters of Credit
under Section 2.20 and the Commitments of the


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 18


<PAGE>   23
Lenders shall automatically be terminated on the Maturity Date. Such commitments
may also terminate as provided in Section 2.10(c) and Article 6.

         (b) Upon at least three Business Days' prior irrevocable written notice
to the Administrative Agent, the Borrower may, at any time, in whole permanently
terminate, or, from time to time, in part permanently reduce, the Total
Commitment; provided, however, that (i) each partial reduction of the Total
Commitment shall be in an integral multiple of $5,000,000 and in a minimum
principal amount of $5,000,000 and (ii) no such termination or reduction shall
be made which would reduce the Total Commitment to an amount less than
$50,000,000, unless the result of such termination or reduction is to reduce the
Total Commitment to $0. The Administrative Agent shall advise the Lenders of any
notice given pursuant to this Section 2.09(b) and of each Lender's portion of
any such termination or reduction of the Total Commitment. Upon termination of
the Total Commitment, the commitment of the Swingline Lender under Section 2.19
to make Swingline Loans and the commitment of the Issuing Bank to issue Letters
of Credit under Section 2.20 shall also terminate.

         (c) Each reduction in the Total Commitment hereunder shall be made
ratably among the Lenders in accordance with their respective Commitments. The
Borrower shall pay to the Administrative Agent for the account of the Lenders,
on the date of each termination or reduction of the Total Commitment, the
Commitment Fees on the amount of the Commitments so terminated or reduced
accrued through the date of such termination or reduction.

         SECTION 2.10. Prepayment Including Prepayment as a Result of a Change
of Control.

         (a) The Borrower shall have the right at any time and from time to time
to prepay any Borrowing, in whole or in part, upon giving telecopy notice (or
telephone notice promptly confirmed by telecopy) to the Administrative Agent:
(i) before 11:00 a.m., New York, New York time, three Business Days prior to
prepayment, in the case of Eurodollar Loans and Negotiated Rate Borrowings which
prepayment shall be accompanied by any amount owed under Section 8.05(b), and
(ii) before 11:00 a.m., New York, New York time, one Business Day prior to
prepayment, in the case of ABR Loans; provided, however, that each partial
prepayment shall be in an amount which is an integral multiple of $1,000,000 and
not less than $3,000,000 or the total amount of the outstanding Borrowing.

         (b) On the date of any termination or reduction of the Total Commitment
pursuant to Section 2.09, the Borrower shall pay or prepay so much of the
Borrowings as shall be necessary in order that the aggregate outstanding
principal amount of the Loans and Swingline Loans will not exceed the sum of the
Total Commitment minus all Letter of Credit Liabilities, after giving effect to
such termination or reduction.

         (c) At least 15 Business Days (or, in the case of any transaction
permitted by Section 5.10 resulting in a Change of Control, at least 45 days)
and not more than 90 days prior to the occurrence of any Change of Control, the
Borrower will give written notice thereof to each Lender. Such notice shall
contain (i) an offer by the Borrower to prepay, on the date of such Change of
Control or, if such notice shall be delivered less than 35 days prior to the
date of such Change of Control, on the date 35 days after the date of such
notice (the "Prepayment Date"), all Loans and Swingline Loans made by each
Lender, together with interest accrued thereon to the Prepayment Date and all
other liquidated obligations owed to such Lender under the terms hereof, (ii)
the estimated amount of accrued interest, showing in reasonable detail the
calculation thereof and (iii) the Borrower's estimate of the date on which such
Change of Control shall occur. Said offer shall be deemed to lapse as to any
such Lender which has not replied affirmatively thereto in writing within 35
days of the giving of such notice. As soon as practicable (and in any event at
least 24


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 19


<PAGE>   24
hours) prior to such Change of Control, the Borrower shall give written
confirmation of the date thereof to each such Lender that has affirmatively
replied to the notice given pursuant to the first sentence of this Section
2.10(c). Borrower shall, on the Prepayment Date, prepay to each Lender that has
affirmatively replied to the notice given pursuant to the first sentence of this
Section 2.10(c) all Loans and funded participation interests in Swingline Loans
then held by such Lender together with accrued interest thereon and all other
liquidated obligations owed to such Lender under the terms hereof. Thereupon,
each Lender that shall have received such prepayment shall have no further
obligation to make Loans or participate in Swingline Loans or Letters of Credit
made or issued after the Prepayment Date and the Total Commitment shall be
reduced by the amount of each such Lender's Commitment; provided that each
Lender that shall have received such prepayment shall continue to have a
participation interest in any Letter of Credit issued prior to the Prepayment
Date or any Swingline Loan outstanding immediately after the Prepayment Date and
shall be entitled to the continued payment of the Fees paid in respect thereof.
The participation interests described in the foregoing sentence shall be
calculated based on the Applicable Percentages determined immediately prior to
the Prepayment Date and each such Lender shall continue to be obligated to fund
its participation interest therein as herein specified as if no prepayment had
occurred. Any Loan made after the Prepayment Date shall be made by the remaining
Lenders and such Lenders shall have participation interests in any Swingline
Loan made after the Prepayment Date and any Letter of Credit issued after the
Prepayment Date based on their Applicable Percentages (calculated without
including the Commitments of the Lenders that shall have received the prepayment
under this Section 2.10 (c)). If requested by the Agent or the Lenders who are
to receive prepayment under this Section 2.10 (c), the Borrower shall use its
commercially reasonable efforts to cause all Letters of Credit that are to be
outstanding as of the Prepayment Date to be terminated as of the Prepayment Date
or as soon thereafter as is possible.

         For the purposes of this Section 2.10(c), a "Change of Control" shall
be deemed to occur if any New Owner shall acquire beneficial ownership of shares
in the Borrower having Voting Rights pertaining thereto which would allow such
New Owner to elect more members of the Board of Directors than could be elected
by the exercise of all Voting Rights pertaining to shares in the Borrower then
owned beneficially by the Norris Family. As used in this Section 2.10(c):

                            (i) "Voting Rights" pertaining to shares of a
                  corporation means the rights to cast votes for the election of
                  directors of such corporation in ordinary circumstances
                  (without consideration of voting rights which exist only in
                  the event of contingencies).

                           (ii) "Norris Family" means all persons who are lineal
                  descendants of D. W. Norris (by birth or adoption), all
                  spouses of such descendants, all estates of such descendants
                  or spouses which are in the course of administration, all
                  trusts for the benefit of such descendants or spouses, and all
                  corporations or other entities in which, directly or
                  indirectly, such descendants or spouses (either alone or in
                  conjunction with other such descendants or spouses) have the
                  right, whether by ownership of stock or other equity interests
                  or otherwise, to direct the management and policies of such
                  corporations or other entities (each such person, spouse,
                  estate, trust, corporation or entity being referred to herein
                  as a "member" of the Norris Family). In addition, so long as
                  any employee stock ownership plan exercises its Voting Rights
                  in the same manner as members of the Norris Family (exclusive
                  of employee stock ownership plans) who have a majority of the
                  Voting Rights exercised by all such members of the Norris
                  Family, such employee stock ownership plan shall be deemed a
                  member of the Norris Family.


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 20


<PAGE>   25
                           (iii) "New Owner" means any Person (other than a
                  member of the Norris Family), or any syndicate or group of
                  Persons (exclusive of all members of the Norris Family) which
                  would be deemed a "person" for the purposes of Section 13(d)
                  of the Exchange Act, who directly or indirectly acquires
                  shares in the Borrower.

         (d) Each notice of prepayment shall specify the prepayment date and the
principal amount of each Borrowing (or portion thereof) to be prepaid, shall be
irrevocable and shall commit the Borrower to prepay such Borrowing (or portion
thereof) by the amount stated therein on the date stated therein. All
prepayments under this Section 2.10 shall be subject to Section 8.05 but
otherwise without premium or penalty. All prepayments under this Section 2.10
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment.

         SECTION 2.11. Reserve Requirements; Change in Circumstances.

         (a) Notwithstanding any other provision herein, if after the date of
this Agreement any change in applicable law or regulation or in the
interpretation or administration thereof by any Governmental Authority charged
with the interpretation or administration thereof (whether or not having the
force of law) shall change the basis of taxation of payments to the Issuing Bank
or any Lender hereunder (except for changes in respect of taxes on the overall
net income of the Issuing Bank or such Lender or its lending office imposed by
the jurisdiction in which its principal executive office or lending office is
located), or shall result in the imposition, modification or applicability of
any reserve, special deposit or similar requirement against assets of, deposits
with or for the account of or credit extended by any Lender or the Issuing Bank,
or shall result in the imposition on any Lender, the Issuing Bank or the London
interbank market of any other condition affecting this Agreement, such Lender's
Commitment, any Eurodollar Loan made by such Lender or any Letter of Credit or
participation interest therein, and the result of any of the foregoing shall be
to increase the cost to such Lender or the Issuing Bank of making or maintaining
any Eurodollar Loan or issuing, maintaining or participating in any Letter of
Credit or to reduce the amount of any sum received or receivable by such Lender
or Issuing Bank hereunder (whether of principal, interest or otherwise) by an
amount deemed by such Lender or the Issuing Bank to be material, then the
Borrower shall, upon receipt of the notice and certificate provided for in
Section 2.11(c), promptly pay to such Lender or the Issuing Bank, as applicable,
such additional amount or amounts as will compensate such Lender or the Issuing
Bank for such additional costs incurred or reduction suffered.

         (b) If any Lender or the Issuing Bank shall have determined that the
adoption of any law, rule, regulation or guideline arising out of the July 1988
report of the Basle Committee on Banking Regulations and Supervisory Practices
entitled "International Convergence of Capital Measurement and Capital
Standards," or the adoption after the date hereof of any other law, rule,
regulation or guideline regarding capital adequacy, or any change in any of the
foregoing or in the interpretation or administration of any of the foregoing by
any Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or the Issuing Bank or any Lender's or the
Issuing Bank's holding company with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on such Lender's or the Issuing Bank's capital or on the capital of such
Lender's or the Issuing Bank's holding company, if any, as a consequence of this
Agreement, such Lender's Commitment, the Loans or Swingline Loans made by such
Lender pursuant hereto, or any Letter of Credit or participation interest
therein to a level below that which such Lender or the Issuing Bank or such
Lender's or the Issuing Bank's holding company could have achieved but for such
adoption, change or compliance (taking into consideration such Lender's or the
Issuing


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 21


<PAGE>   26
Bank's policies and the policies of such Lender's or the Issuing Bank's holding
company with respect to capital adequacy) by an amount deemed by such Lender or
the Issuing Bank to be material, then from time to time such additional amount
or amounts as will compensate such Lender or the Issuing Bank for any such
reduction suffered will be paid by the Borrower to such Lender or the Issuing
Bank, as applicable.

         (c) A certificate of each affected party setting forth such amount or
amounts as shall be necessary to compensate such party or its holding company as
specified in paragraph (a) or (b) above, as the case may be, and containing an
explanation in reasonable detail of the manner in which such amount or amounts
shall have been determined, shall be delivered to the Borrower, and shall be
conclusive absent manifest error. The Borrower shall pay each Lender or the
Issuing Bank, as applicable, the amount shown as due on any such certificate
delivered by it within 10 days after its receipt of the same. Each Lender or the
Issuing Bank shall give prompt notice to the Borrower of any event of which it
has knowledge, occurring after the date hereof, that it has determined will
require compensation by the Borrower pursuant to this Section; provided,
however, that failure by such Lender or the Issuing Bank to give such notice
shall not constitute a waiver of such party's right to demand compensation
hereunder.

         (d) Failure on the part of any party to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
return on capital of the type described in paragraph (a) or (b) of this Section
2.11 with respect to any period shall not constitute a waiver of such party's
right to demand compensation with respect to such period or any other period;
provided, however, that neither any Lender nor the Issuing Bank shall be
entitled to compensation under this Section 2.11 for any costs incurred or
reductions suffered with respect to any date unless it shall have notified the
Borrower that it will demand compensation for such costs or reductions under
paragraph (c) above not more than 90 days after the later of (i) such date and
(ii) the date on which it shall have become aware of such costs or reductions.
The protection of this Section shall be available to each Lender and the Issuing
Bank regardless of any possible contention of the invalidity or inapplicability
of the law, rule, regulation, guideline or other change or condition which shall
have occurred or been imposed.

         (e) Each Lender and the Issuing Bank agrees that it will designate a
different lending or issuing office, as applicable, if such designation will
avoid the need for, or reduce the amount of, such compensation and will not, in
its reasonable judgment, be disadvantageous to its interests.

         SECTION 2.12. Change in Legality.

         (a) Notwithstanding any other provision herein, if any change in any
law or regulation or in the interpretation thereof by any Governmental Authority
charged with the administration or interpretation thereof shall make it unlawful
for any Lender to make or maintain any Eurodollar Loan or to give effect to its
obligations as contemplated hereby with respect to any Eurodollar Loan, then, by
written notice to the Borrower and to the Administrative Agent, such Lender may:

                           (i) declare that Eurodollar Loans will not thereafter
                  be made by such Lender hereunder, whereupon any request for a
                  Eurodollar Borrowing shall, as to such Lender only, be deemed
                  a request for an ABR Loan unless such declaration shall be
                  subsequently withdrawn (any Lender delivering such a
                  declaration hereby agreeing to withdraw such declaration
                  promptly upon determining that such event of illegality no
                  longer exists); and


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 22


<PAGE>   27
                           (ii) require that all outstanding Eurodollar Loans
                  made by it be converted to ABR Loans, in which event all such
                  Eurodollar Loans shall be automatically converted to ABR Loans
                  as of the effective date of such notice as provided in
                  paragraph (b) below.

         In the event any Lender shall exercise its rights under (i) or (ii)
above, all payments and prepayments of principal which would otherwise have been
applied to repay the Eurodollar Loans that would have been made by such Lender
or the Converted Eurodollar Loans of such Lender shall instead be applied to
repay the ABR Loans made by such Lender in lieu of, or resulting from the
Conversion of, such Eurodollar Loans.

         (b) For purposes of this Section 2.12, a notice by any Lender shall be
effective as to each Eurodollar Loan, if lawful, on the last day of the Interest
Period currently applicable to such Eurodollar Loan; in all other cases such
notice shall be effective on the date of receipt.

         SECTION 2.13. Pro Rata Treatment. Except as required under Sections
2.12 and 2.17, each Borrowing (other than a Borrowing comprised of a Swingline
Loan), each payment or prepayment of principal of any Borrowing (other than a
Borrowing comprised of a Swingline Loan), each payment of interest on the Loans,
each payment of the Commitment Fees, each Conversion or Continuation of any
Loans, and each reduction of the Total Commitment, shall be allocated pro rata
among the Lenders in accordance with their Applicable Percentage.

         SECTION 2.14. Sharing of Setoffs. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim, or
pursuant to a secured claim under Section 506 of Title 11 of the United States
Code or other security or interest arising from, or in lieu of, such secured
claim, received by such Lender under any applicable bankruptcy, insolvency or
other similar law or otherwise, or by any other means, obtain payment (voluntary
or involuntary) in respect of any Loan or Loans as a result of which the unpaid
principal portion of its Loans shall be proportionately less than the unpaid
principal portion of the Loans of any other Lender, it shall be deemed
simultaneously to have purchased from such other Lender at face value, and shall
promptly pay to such other Lender the purchase price for, a participation in the
Loans of such other Lender, so that the aggregate unpaid principal amount of the
Loans and participations in the Loans held by each Lender shall be in the same
proportion to the aggregate unpaid principal amount of all Loans then
outstanding as the principal amount of its Loans prior to such exercise of
banker's lien, setoff or counterclaim or other event was to the principal amount
of all Loans outstanding prior to such exercise of banker's lien, setoff or
counterclaim or other event; provided, however, that, if any such purchase or
purchases or adjustments shall be made pursuant to this Section 2.14 and the
payment giving rise thereto shall thereafter be recovered, such purchase or
purchases or adjustments shall be rescinded to the extent of such recovery and
the purchase price or prices or adjustment restored without interest. The
Borrower expressly consents to the foregoing arrangements and agrees that any
Lender holding a participation in a Loan deemed to have been so purchased may
exercise any and all rights of banker's lien, setoff or counterclaim with
respect to any and all moneys owing by the Borrower to such Lender by reason
thereof as fully as if such Lender had made a Loan in the amount of such
participation.

         SECTION 2.15. Payments.

         (a) The Borrower shall make each payment (including principal of or
interest on any Borrowing or any Fees or other amounts hereunder) from an
account in the United States not later than 12:00 noon, New York, New York time,
on the date when due in dollars to the Administrative Agent at its offices at 1
Chase Manhattan Plaza, 8th Floor, New York, New York 10081 or, in the case of
payments to be made directly to another party hereto in accordance with the
terms hereof, to such party as such party shall direct, in each


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 23


<PAGE>   28
case, in immediately available funds. All payments made by the Borrower shall be
made without condition or deduction for any counterclaim, defense, recoupment or
setoff.

         (b) Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder shall become due, or otherwise
would occur, on a day that is not a Business Day, such payment may be made on
the next succeeding Business Day, and such extension of time shall in such case
be included in the computation of interest or Fees, if applicable.

         SECTION 2.16. Taxes.

         (a) Any and all payments of principal and interest on any Borrowings,
or of any Fees or indemnity or expense reimbursements by the Borrower hereunder
("Borrower Payments") shall be made, in accordance with Section 2.15, free and
clear of and without deduction for any and all current or future federal, state,
local and other governmental taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect to the Borrower Payments, but
only to the extent reasonably attributable to the Borrower Payments, excluding
(i) income taxes imposed on the net income of the Administrative Agent, the
Issuing Bank or any Lender (or any transferee or assignee thereof, including a
participation holder (any such entity a "Transferee")) and (ii) franchise taxes
imposed on the net income of the Administrative Agent, the Issuing Bank or any
Lender (or Transferee), in each case by the jurisdiction under the laws of which
such party (or Transferee) is organized or doing business through offices or
branches located therein, or any political subdivision thereof (all such
nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities, collectively or individually, "Taxes"). If the Borrower shall be
required to deduct any Taxes from or in respect of any sum payable hereunder to
the Administrative Agent, the Issuing Bank or any Lender (or any Transferee),
(i) the sum payable shall be increased by the amount (an "additional amount")
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.16) such party (or
Transferee) (as the case may be) shall receive an amount equal to the sum it
would have received had no such deductions been made, (ii) the Borrower shall
make such deductions and (iii) the Borrower shall pay the full amount deducted
to the relevant Governmental Authority in accordance with applicable law.

         (b) In addition, the Borrower shall pay to the relevant Governmental
Authority in accordance with applicable law any current or future stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement or the
Fee Letter ("Other Taxes").

         (c) The Borrower shall indemnify the Administrative Agent, the Issuing
Bank and each Lender (or Transferee thereof) for the full amount of Taxes and
Other Taxes with respect to Borrower Payments paid by such party (or
Transferee), as the case may be, and any liability (including penalties,
interest and expenses (including reasonable attorney's fees and expenses))
arising therefrom or with respect thereto, whether or not such Taxes or Other
Taxes were correctly or legally asserted by the relevant Governmental Authority.
A certificate setting forth and containing an explanation in reasonable detail
of the manner in which such amount shall have been determined and the amount of
such payment or liability prepared by the Administrative Agent, the Issuing Bank
or a Lender, absent manifest error, shall be final, conclusive and binding for
all purposes. Such indemnification shall be made within 30 days after the date
the applicable party makes written demand therefor.

         (d) If the Administrative Agent, the Issuing Bank or a Lender (or
Transferee) shall become aware that it is entitled to claim a refund from a
Governmental Authority in respect of Taxes or Other Taxes as to which it has
been indemnified by the Borrower, or with respect to which the Borrower has paid


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 24


<PAGE>   29
additional amounts, pursuant to this Section 2.16, it shall promptly notify the
Borrower of the availability of such refund claim and shall, within 30 days
after receipt of a request by the Borrower, make a claim to such Governmental
Authority for such refund at the Borrower's expense. If such party receives a
refund (including pursuant to a claim for refund made pursuant to the preceding
sentence) in respect of any Taxes or Other Taxes as to which it has been
indemnified by the Borrower or with respect to which the Borrower had paid
additional amounts pursuant to this Section 2.16, it shall within 30 days from
the date of such receipt pay over such refund to the Borrower (but only to the
extent of indemnity payments made, or additional amounts paid, by the Borrower
under this Section 2.16 with respect to the Taxes or Other Taxes giving rise to
such refund), net of all of its out-of-pocket expenses and without interest
(other than interest paid by the relevant Governmental Authority with respect to
such refund); provided, however, that the Borrower, upon the request of such
party, agrees to repay the amount paid over to the Borrower (plus penalties,
interest or other charges) under this Section 2.16(d) in the event the party is
required to repay such refund to such Governmental Authority.

         (e) As soon as practicable, but in any event within 30 days, after the
date of any payment of Taxes or Other Taxes by the Borrower to the relevant
Governmental Authority, the Borrower will deliver to the Administrative Agent,
at its address referred to in Section 8.01, the original or a certified copy of
a receipt issued by such Governmental Authority evidencing payment thereof.

         (f) Without prejudice to the survival of any other agreement contained
herein, the agreements and obligations contained in this Section 2.16 shall
survive the payment in full of the principal of and interest on all Borrowings
made hereunder.

         (g) Each Lender (or Transferee) that is organized under the laws of a
jurisdiction other than the United States, any State thereof or the District of
Columbia (a "Non-U.S. Lender") shall deliver to the Borrower and the
Administrative Agent two copies of either United States Internal Revenue Service
Form 1001 or Form 4224 (or other applicable form), properly completed and duly
executed by such Non-U.S. Lender claiming complete exemption from, or reduced
rate of, United States Federal withholding tax on payments by the Borrower under
this Agreement. Such forms shall be delivered by each Non-U.S. Lender on or
before the date it becomes a party to this Agreement (or, in the case of a
Transferee that is a participation holder, on or before the date such
participation holder becomes a Transferee hereunder) and on or before the date,
if any, such Non-U.S. Lender changes its applicable lending office by
designating a different lending office (a "New Lending Office"). In addition,
each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Non-U.S. Lender.
Notwithstanding any other provision of this Section 2.16(g), a Non-U.S. Lender
shall not be required to deliver any form pursuant to this Section 2.16(g) that
such Non-U.S. Lender is not legally able to deliver.

         (h) The Borrower shall not be required to indemnify any Non-U.S. Lender
(including any Transferee), or to pay any additional amounts to any Non-U.S.
Lender (including any Transferee), in respect of federal, state, local or other
governmental withholding tax pursuant to paragraph (a) or (c) above to the
extent that: (i) the obligation to withhold amounts with respect to federal,
state, local or other governmental withholding tax existed on the date such
Non-U.S. Lender became a party to this Agreement (or, in the case of a
Transferee that is a participation holder, on the date such participation holder
became a Transferee hereunder) or, with respect to payments to a New Lending
Office, the date such Non-U.S. Lender designated such New Lending Office with
respect to a Loan; provided, however, that this clause (i) shall not apply to
any Transferee or New Lending Office that becomes a Transferee or New Lending
Office as a result of an assignment, participation, transfer or designation made
at the request of the Borrower; and provided further, however, that this clause
(i) shall not apply to the extent the indemnity payment or additional amounts
any


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 25


<PAGE>   30
Transferee, or Lender (or Transferee) through a New Lending Office, would be
entitled to receive (without regard to this clause (h)) do not exceed the
indemnity payment or additional amounts that the Person making the assignment,
participation or transfer to such Transferee, or Lender (or Transferee) making
the designation of such New Lending Office, would have been entitled to receive
in the absence of such assignment, participation, transfer or designation or
(ii) the obligation to pay such additional amounts or such indemnity payments
would not have arisen but for a failure by such Non-U.S. Lender (including any
Transferee) to comply with the provisions of paragraph (g) above and (i) below.

         (i) The Administrative Agent, the Issuing Bank or any Lender (or
Transferee) claiming any indemnity payment or additional amounts payable
pursuant to this Section 2.16 shall use reasonable efforts (consistent with
legal and regulatory restrictions) to file any certificate or document
reasonably requested in writing by the Borrower or to change the jurisdiction of
its applicable lending office if the making of such a filing or change would
avoid the need for or reduce the amount of any such indemnity payment or
additional amounts that may thereafter accrue and would not, in the good faith
determination of the Administrative Agent, the Issuing Bank or such Lender (or
Transferee), be otherwise disadvantageous to its interests.

         (j) Nothing contained in this Section 2.16 shall require the
Administrative Agent, the Issuing Bank or a Lender (or Transferee) to make
available to the Borrower any of its tax returns (or any other information) that
it deems to be confidential or proprietary.

         SECTION 2.17. Assignment of Commitments Under Certain Circumstances. In
the event that any Lender shall have delivered a notice or certificate pursuant
to Section 2.11 or 2.12, or the Borrower shall be required to make additional
payments to any Lender under Section 2.16 or the Borrower is entitled to
exercise its right to require assignment under Section 2.21 hereof, the Borrower
shall have the right, at its own expense, upon notice to such Lender and the
Administrative Agent, to require such Lender to transfer and assign without
recourse (in accordance with and subject to the restrictions contained in
Section 8.04) all such Lender's interests, rights and obligations contained
hereunder to another financial institution approved by the Administrative Agent
and the Borrower (which approval shall not be unreasonably withheld) which shall
assume such obligations; provided that (i) no such assignment shall conflict
with any law, rule or regulation or order of any Governmental Authority and (ii)
the assignee or the Borrower, as the case may be, shall pay to the affected
Lender in immediately available funds on the date of such assignment the
principal of and interest and Fees accrued to the date of payment on the Loans
and Swingline Loans made by it hereunder and all other amounts accrued for its
account or owed to it hereunder.

         SECTION 2.18. Payments by Administrative Agent to the Lenders. Any
payment received by the Administrative Agent hereunder for the account of a
Lender shall be paid to such Lender by 4:00 p.m. New York, New York time on (a)
the Business Day the payment is received in immediately available funds, if such
payment is received by 11:00 a.m. New York, New York time and (b) if such
payment is received after 11:00 a.m. New York, New York time, on the next
Business Day.

         SECTION 2.19. Swingline Loans. Subject to the terms and conditions set
forth herein, the Swingline Lender agrees to make advances (each such advance a
"Swingline Loan") to the Borrower from time to time on and after the date
hereof, until the earlier of the Maturity Date or the termination of the
Commitments hereunder in an aggregate principal amount at any time outstanding
that will not result in (i) the aggregate principal amount of outstanding
Swingline Loans exceeding $20,000,000 and (ii) the total Revolving Exposures
exceeding the Total Commitment. The Swingline Loans comprising any Borrowing
shall be in an amount which is an integral multiple of $500,000 and not less
than $1,000,000 (or an aggregate principal amount equal to the sum of
$20,000,000 minus all the Swingline Loans then outstanding). Within


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 26


<PAGE>   31
the foregoing limits and subject to the terms and conditions set forth herein,
the Borrower may borrow, prepay and reborrow Swingline Loans.

         (a) Swingline Request Procedure. To request a Swingline Loan, the
Borrower shall notify the Administrative Agent of such request by telephone
(confirmed by telecopy), not later than 11:00 a.m., New York, New York time, on
the day of a proposed Swingline Loan by use of a duly completed Borrowing
Request. Each such notice shall be irrevocable and shall specify: (i) the
requested date of such Borrowing (which shall be a Business Day), (ii) the
amount of the requested Swingline Loan, (iii) whether the Swingline Loan is to
be a Eurodollar Borrowing, an ABR Borrowing or a Negotiated Rate Borrowing, and
(iv) in the event of a Negotiated Rate Borrowing is selected, the requested
duration of the Interest Period therefor and the requested interest rate to be
applicable thereto. If no election as to the type of Borrowing is specified in
any notice, then the requested Borrowing shall be an ABR Borrowing. Each
Interest Period with respect to a Eurodollar Borrowing that is a Swingline Loan
shall be one month's duration. The Administrative Agent will promptly advise the
Swingline Lender of any such notice received from the Borrower. The Swingline
Lender shall make each Swingline Loan available to the Borrower by means of a
credit to the account or accounts specified from time to time in one or more
notices delivered by the Borrower to the Swingline Lender (or, in the case of a
Swingline Loan made to finance the reimbursement of an LC Disbursement as
provided in Section 2.20(d), by remittance to the Issuing Bank) by 3:00 p.m.,
New York, New York time, on the requested date of such Swingline Loan. The
Swingline Lender shall notify the Borrower on the date the Borrower requests a
Negotiated Rate Borrowing if the Swingline Lender will not agree to the rate
requested in such notice to apply to such Borrowing or the duration of the
related Interest Period. If the Borrower and the Swingline Lender can not agree
on the Negotiated Rate for a Negotiated Rate Borrowing, the Negotiated Rate
Borrowing shall not be available hereunder. The determination by the Swingline
Lender of the Negotiated Rate applicable to a Negotiated Rate Borrowing shall be
conclusive absent manifest error.

         (b) Lender Participation. The Swingline Lender may by written notice
given to the Administrative Agent not later than 11:00 a.m., New York, New York
time, on any Business Day require the Lenders to acquire participations on such
Business Day in all or a portion of the Swingline Loans outstanding. Such notice
shall specify the aggregate amount of Swingline Loans in which the Lenders will
participate. Promptly upon receipt of such notice, the Administrative Agent will
give notice thereof to each Lender, specifying in such notice such Lender's
Applicable Percentage of such Swingline Loans. Each Lender hereby absolutely and
unconditionally agrees, upon receipt of notice as provided above, to pay to the
Administrative Agent, for the account of the Swingline Lender, such Lender's
Applicable Percentage of such Swingline Loans. Each Lender acknowledges and
agrees that its obligation to acquire participations in Swingline Loans pursuant
to this paragraph is absolute and unconditional and shall not be affected by any
circumstance whatsoever, including the occurrence and continuance of a Default
or Event of Default or reduction or termination of the Commitments, and that
each such payment shall be made without any offset, abatement, withholding or
reduction whatsoever; provided that (i) the obligations of a Lender to fund its
participation in a Swingline Loan may be subject to avoidance by a Lender if
such Lender proves that the Swingline Lender knew (or with the exercise of care
should have known) that the conditions to the making of the Swingline Loan were
not satisfied and (ii) a Lender shall not have an obligation to acquire or fund
a participation in Swingline Loans if that obligation of the Lender has been
terminated or assigned to another Person in accordance with Section 2.10(c),
Section 2.21 or Section 8.04. The parties hereto expressly agree that, in the
absence of gross negligence or willful misconduct on the part of the Swingline
Lender (as finally determined by a court of competent jurisdiction), the
Swingline Lender shall be deemed to have exercised care. Each Lender shall
comply with its obligation under this paragraph by wire transfer of immediately
available funds, and the Administrative Agent shall promptly pay to the
Swingline Lender the amounts so received by it from the Lenders. The
Administrative Agent shall notify the Borrower of any participations in any
Swingline Loan acquired pursuant to this paragraph, and thereafter payments in
respect of such Swingline Loan shall be made to the Administrative Agent and not
to the Swingline Lender. Any amounts


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 27


<PAGE>   32
received by the Swingline Lender from the Borrower (or other party on behalf of
the Borrower) in respect of a Swingline Loan after receipt by the Swingline
Lender of the proceeds of a sale of participations therein shall be promptly
remitted to the Administrative Agent; any such amounts received by the
Administrative Agent shall be promptly remitted by the Administrative Agent to
the Lenders that shall have made their payments pursuant to this paragraph and
to the Swingline Lender, as their interests may appear. The purchase of
participations in a Swingline Loan pursuant to this paragraph shall not relieve
the Borrower of its obligation for the payment thereof in full, notwithstanding
any Default or Event of Default which may exist.

         (c) Repayment. Swingline Loans shall be repaid by the Borrower in
accordance with Section 2.05.

         SECTION 2.20. Letters of Credit. Subject to the terms and conditions
set forth herein, the Borrower may request the issuance of letters of credit
(each a "Letter of Credit") for its own account or for its or a Subsidiary's
benefit, in a form reasonably acceptable to the Administrative Agent and the
Issuing Bank, at any time and from time to time on and after the date hereof
until the earlier of five Business Days prior to the Maturity Date or the
termination of the Commitments hereunder. In the event of any inconsistency
between the terms and conditions of this Agreement and the terms and conditions
of any form of letter of credit application or other agreement submitted by the
Borrower to, or entered into by the Borrower with, the Issuing Bank relating to
any Letter of Credit, the terms and conditions of this Agreement shall control.

         (a) Notice of Issuance, Amendment, Renewal, Extension; Certain
Conditions. To request the issuance of a Letter of Credit (or the amendment,
renewal or extension of an outstanding Letter of Credit), the Borrower shall
hand deliver or telecopy (or transmit by electronic communication, if
arrangements for doing so have been approved by the Issuing Bank) to the Issuing
Bank and the Administrative Agent (reasonably in advance of the requested date
of issuance, amendment, renewal or extension) a notice requesting the issuance
of a Letter of Credit, or identifying the Letter of Credit to be amended,
renewed or extended, and specifying the date of issuance, amendment, renewal or
extension (which shall be a Business Day), the date on which such Letter of
Credit is to expire (which shall comply with paragraph (b) of this Section), the
amount of such Letter of Credit, the name and address of the beneficiary thereof
and such other information as shall be necessary to prepare, amend, renew or
extend such Letter of Credit. If requested by the Issuing Bank, the Borrower
also shall submit a letter of credit application on the Issuing Bank's standard
form (or in such other form as may be mutually agreed between the Borrower and
the Issuing Bank) in connection with any request for a Letter of Credit. A
Letter of Credit shall be issued, amended, renewed or extended only if (and upon
issuance, amendment, renewal or extension of each Letter of Credit the Borrower
shall be deemed to represent and warrant that), after giving effect to such
issuance, amendment, renewal or extension (i) the Letter of Credit Liabilities
shall not exceed $25,000,000 and (ii) the total Revolving Exposures of all
Lenders shall not exceed the Total Commitment.

         (b) Expiration Date. Each Letter of Credit shall expire at or prior to
the close of business on the date that is five Business Days prior to the
Maturity Date.

         (c) Participations. By the issuance of a Letter of Credit (or an
amendment to a Letter of Credit increasing the amount thereof) and without any
further action on the part of the Issuing Bank or the Lenders, the Issuing Bank
hereby grants to each Lender, and each Lender hereby acquires from the Issuing
Bank, a participation in such Letter of Credit equal to such Lender's Applicable
Percentage of the aggregate amount available to be drawn under such Letter of
Credit. In consideration and in furtherance of the foregoing, each Lender hereby
absolutely and unconditionally agrees to pay to the Administrative Agent, for
the account of


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 28


<PAGE>   33
the Issuing Bank, such Lender's Applicable Percentage of each LC Disbursement
made by the Issuing Bank and not reimbursed by the Borrower on the date due as
provided in paragraph (d) of this Section, or of any reimbursement payment
required to be refunded to the Borrower for any reason. Each Lender acknowledges
and agrees that its obligation to acquire participations pursuant to this
paragraph in respect of Letters of Credit is absolute and unconditional and
shall not be affected by any circumstance whatsoever, including any amendment,
renewal or extension of any Letter of Credit or the occurrence and continuance
of a Default or Event of Default or reduction or termination of the Commitments,
and that each such payment shall be made without any offset, abatement,
withholding or reduction whatsoever; provided that (i) the obligations of a
Lender to fund its participation in a Letter of Credit may be subject to
avoidance by that Lender if (A) the Issuing Bank knew (or with the exercise of
care should have known) that the conditions to the issuance of the Letter of
Credit were not satisfied or (B) the Issuing Bank failed to exercise care when
determining whether drafts and other documents presented under the Letter of
Credit complied with the terms thereof and (ii) a Lender shall not have an
obligation to acquire or fund a participation in a Letter of Credit if that
obligation of the Lender has been terminated or assigned to another Person in
accordance with Section 2.10(c), Section 2.21 or Section 8.04. The parties
hereto expressly agree that, in the absence of gross negligence or willful
misconduct on the part of the Issuing Bank (as finally determined by a court of
competent jurisdiction), the Issuing Bank shall be deemed to have exercised
care.

         (d) Reimbursement. If the Issuing Bank shall make any LC Disbursement
in respect of a Letter of Credit, the Borrower shall reimburse such LC
Disbursement by paying to the Administrative Agent an amount equal to such LC
Disbursement not later than 12:00 noon, New York, New York time, on the date
that such LC Disbursement is made, if the Borrower shall have received notice of
such LC Disbursement prior to 10:00 a.m., New York, New York time, on such date,
or, if such notice has not been received by the Borrower prior to such time on
such date, then not later than 12:00 noon, New York, New York time, on (i) the
Business Day that the Borrower receives such notice, if such notice is received
prior to 10:00 a.m., New York, New York time, on the day of receipt, or (ii) the
Business Day immediately following the day that the Borrower receives such
notice, if such notice is not received prior to such time on the day of receipt;
provided that the Borrower may, subject to the conditions to borrowing set forth
herein, request that such payment be financed with a Loan or Swingline Loan in
an equivalent amount and, to the extent so financed, the Borrower's obligation
to make such payment shall be discharged and replaced by the resulting Loan or
Swingline Loan. If the Borrower fails to make such reimbursement payment when
due, the Administrative Agent shall notify each Lender of the applicable LC
Disbursement, the payment then due from the Borrower in respect thereof and such
Lender's Applicable Percentage thereof. Promptly following receipt of such
notice, each Lender shall pay to the Administrative Agent its Applicable
Percentage of the reimbursement payment then due from the Borrower, and the
Administrative Agent shall promptly pay to the Issuing Bank the amounts so
received by it from the Lenders. Promptly following receipt by the
Administrative Agent of any payment from the Borrower pursuant to this
paragraph, the Administrative Agent shall distribute such payment to the Issuing
Bank or, to the extent that Lenders have made payments pursuant to this
paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing
Bank as their interests may appear. Any payment made by a Lender pursuant to
this paragraph to reimburse the Issuing Bank for any LC Disbursement (other than
the funding of a Loan as contemplated above) shall not constitute a Loan and
shall not relieve the Borrower of its obligation to reimburse such LC
Disbursement.

         (e) Obligations Absolute. The Borrower's obligations to reimburse LC
Disbursements as provided in paragraph (d) of this Section shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement under any and all circumstances whatsoever and
irrespective of (i) any lack of validity or enforceability of any Letter of
Credit or this Agreement, or any term or provision therein, (ii) any draft or
other document presented under a Letter of Credit proving to be forged,
fraudulent or invalid in any respect or any statement therein being untrue or
inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of
Credit against presentation of


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 29


<PAGE>   34
a draft or other document that does not comply with the terms of such Letter of
Credit, or (iv) any other event or circumstance whatsoever, whether or not
similar to any of the foregoing, that might, but for the provisions of this
Section, constitute a legal or equitable discharge of, or provide a right of
setoff against, the Borrower's obligations hereunder. Neither the Administrative
Agent, the Lenders nor the Issuing Bank, nor any of their agents, officers or
employees, shall have any liability or responsibility by reason of or in
connection with the issuance or transfer of any Letter of Credit or any payment
or failure to make any payment thereunder (irrespective of any of the
circumstances referred to in the preceding sentence), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the
Issuing Bank; provided that the foregoing shall not be construed to excuse the
Issuing Bank from liability to the Borrower to the extent of any direct damages
(as opposed to consequential damages, claims in respect of which are hereby
waived by the Borrower to the extent permitted by applicable law) suffered by
the Borrower that are caused by the Issuing Bank's failure to exercise care when
determining whether drafts and other documents presented under a Letter of
Credit comply with the terms thereof. The parties hereto expressly agree that,
in the absence of gross negligence or willful misconduct on the part of the
Issuing Bank (as finally determined by a court of competent jurisdiction), the
Issuing Bank shall be deemed to have exercised care in each such determination.
In furtherance of the foregoing and without limiting the generality thereof, the
parties agree that, with respect to documents presented which appear on their
face to be in substantial compliance with the terms of a Letter of Credit, the
Issuing Bank may, in its sole discretion, either accept and make payment upon
such documents without responsibility for further investigation, regardless of
any notice or information to the contrary, or refuse to accept and make payment
upon such documents if such documents are not in strict compliance with the
terms of such Letter of Credit.

         (f) Disbursement Procedures. The Issuing Bank shall, promptly following
its receipt thereof, examine all documents purporting to represent a demand for
payment under a Letter of Credit. The Issuing Bank shall promptly notify the
Administrative Agent and the Borrower by telephone (confirmed by telecopy) of
such demand for payment and whether the Issuing Bank has made or will make an LC
Disbursement thereunder; provided that any failure to give or delay in giving
such notice shall not relieve the Borrower of its obligation to reimburse the
Issuing Bank and the Lenders with respect to any such LC Disbursement.

         (g) Interim Interest. If the Issuing Bank shall make any LC
Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in
full on the date such LC Disbursement is made in accordance with paragraph (d)
of this Section, the unpaid amount thereof shall bear interest, for each day
from and including the date such LC Disbursement is made to but excluding the
date that the Borrower reimburses such LC Disbursement, at the rate per annum
then applicable to ABR Loans; provided that, if the Borrower fails to reimburse
such LC Disbursement when due pursuant to paragraph (d) of this Section, then
Section 2.07 shall apply. Interest accrued pursuant to this paragraph shall be
for the account of the Issuing Bank, except that interest accrued on and after
the date of payment by any Lender pursuant to paragraph (c) of this Section to
reimburse the Issuing Bank shall be for the account of such Lender to the extent
of such payment.

(h) Replacement of the Issuing Bank. The Issuing Bank may be replaced
at any time by written agreement among the Borrower, the Administrative Agent,
the replaced Issuing Bank and the successor Issuing Bank. The Administrative
Agent shall notify the Lenders of any such replacement of the Issuing Bank. At
the time any such replacement shall become effective, the Borrower shall pay all
unpaid fees accrued for the account of the replaced Issuing Bank pursuant to
this Agreement. From and after the effective date of any such replacement, (i)
the successor Issuing Bank shall have all the rights and obligations of the
Issuing Bank under this Agreement with respect to Letters of Credit to be issued
thereafter and


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 30


<PAGE>   35
(ii) references herein to the term "Issuing Bank" shall be deemed to refer to
such successor or to any previous Issuing Bank, or to such successor and all
previous Issuing Banks, as the context shall require. After the replacement of
an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto
and shall continue to have all the rights and obligations of an Issuing Bank
under this Agreement with respect to Letters of Credit issued by it prior to
such replacement, but shall not be required to issue additional Letters of
Credit.

         SECTION 2.21. Extension of Maturity Date. Subject to the following
provisions, the initial Maturity Date set forth herein and any Maturity Date
hereafter established in accordance with this Section 2.21 may be changed to a
date not to exceed, in each case, the date 363 days after the effective date of
the change. By written notice to Administrative Agent delivered on or before
November 15 of each year, Borrower may request a change to the then effective
Maturity Date. Immediately upon receipt of such notice, the Administrative Agent
shall deliver a copy to each Lender. After receipt of such notice and prior to
the December 15 of such year, each Lender shall provide the Administrative Agent
and the Borrower with a written consent or rejection of the Borrower's request.
The decision whether to accept or reject the Borrower's request shall be made by
each Lender in its sole discretion based on such information as it may deem
necessary, and no Lender shall have any obligation to agree to any change in the
Maturity Date. The failure of a Lender to respond to any such request shall be
deemed a rejection of such request effective as of the applicable December 15.
If with respect to a request of the Borrower under this Section 2.21, Lenders
holding at least 50% of the Revolving Exposures and unused Commitments have
agreed to the requested change to the Maturity Date and at least one or more of
the Lenders is not willing to agree to a change in the Maturity Date, then on or
before the then current Maturity Date, by notice to the Administrative Agent and
the Lenders, the Borrower may take either one or a combination of the following
actions: (i) terminate the Commitment of each Lender that did not agree to the
change in the Maturity Date (and the Total Commitment shall thereafter be
reduced accordingly) or (ii) require each such Lender to transfer and assign all
its right, title, interest and obligations hereunder in accordance with Section
2.17 to one or more financial institutions, each as approved by the Borrower and
the Administrative Agent. If a Lender's Commitment is terminated in accordance
with this Section 2.21, (i) the Borrower shall on the effective date of the
termination, prepay to such Lender all Loans and funded participation interests
in Swingline Loans then held by such Lender together with accrued interest and
Fees thereon and all other liquidated obligations owed to such Lender under the
terms hereof (and thereupon, such Lender shall have no further obligation to
make Loans or participate or fund participations in Swingline Loans or Letters
of Credit) and (ii) after giving effect to the termination of the Commitments
that are being terminated in accordance with this Section 2.21, the Lenders who
have agreed to extend the Maturity Date will make appropriate assignments among
themselves of the Loans outstanding hereunder in amounts sufficient so that
after giving effect thereto, the Loans shall be held by the remaining Lenders
pro rata according to their respective Applicable Percentages.

                                   ARTICLE 3.

                         REPRESENTATIONS AND WARRANTIES

         Borrower represents and warrants to each of the Lenders and the Issuing
Bank as follows:

         SECTION 3.01. Organization; Powers. Borrower (a) is a corporation duly

(A) any provision of any law, statute, rule or regulation to which the Borrower

Applicable Governmental Authority or (C) any provision of any Material
indenture, agreement or other instrument to which the Borrower or any of its
Subsidiaries is a party or by which it or any of its property is or may be bound
(including the Revolving Credit Facility Agreement dated as of July 29, 1999
among Borrower, Chase Bank of Texas, National Association, as administrative
agent and the other parties named therein and the Senior Note Purchase
Agreements and the Indebtedness limitations set forth in Sections 10.4 and 10.9
of the Senior Note Purchase Agreements), (ii) be in conflict with, result in a
breach of or constitute (alone or with notice or lapse of time or both) a
default under any such indenture, agreement or other instrument or (iii) result
in the creation or imposition of any Lien upon any property or assets of the
Borrower.

         SECTION 3.03. Enforceability. This Agreement constitutes a legal, valid
and binding obligation of the Borrower enforceable in accordance with its terms,
as such enforceability may be limited by (i) applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of
creditors' rights generally and (ii) general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

         SECTION 3.04. Governmental Approvals. No action, consent or approval
of, registration or filing with or other action by any Applicable Governmental
Authority is or will be required in connection with the Transactions, to the
extent they relate to the Borrower.

Subsidiary, the correct name thereof, the jurisdiction of its organization, the
percentage of shares of each class of its capital stock or similar equity
interests outstanding owned by the Borrower and each other Subsidiary, and
specifying whether such Subsidiary is designated a Restricted Subsidiary.

         (b) All of the outstanding shares of capital stock or similar equity
interests of each Subsidiary shown in Schedule 3.05 as being owned by the
Borrower and its Subsidiaries have been validly issued, are fully paid and
nonassessable and are owned by the Borrower or another Subsidiary free and clear
of any Lien (except as otherwise disclosed in Schedule 3.05).

         (c) Each Subsidiary identified in Schedule 3.05 is a corporation or
other legal entity duly organized, validly existing and in good standing under
the laws of its jurisdiction of organization, and is duly qualified as a foreign
corporation or other legal entity and is in good standing in each jurisdiction
in which such qualification is required by law, other than those jurisdictions
as to which the failure to be so qualified or in good standing would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. Each such Subsidiary has the corporate or other power and
authority to own or hold under lease the properties it purports to own or hold
under lease and to transact the business it transacts and proposes to transact.


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 32


<PAGE>   37
         SECTION 3.06. Financial Statements. The Borrower has delivered to some
or all of the Lenders copies of the financial statements of the Borrower and its
Subsidiaries listed on Schedule 3.06. All of the financial statements listed on
Schedule 3.06 (including in each case the related schedules and notes) fairly
present in all material respects the consolidated financial position of the
Borrower and its Subsidiaries, and of the Borrower and its Restricted
Subsidiaries, as of the respective dates specified in such Schedule and the
consolidated results of their operations and cash flows for the respective
periods so specified and have been prepared in accordance with GAAP consistently
applied throughout the periods involved except as set forth in the notes thereto
(subject, in the case of any interim financial statements, to normal year-end
adjustments). Except as disclosed in the financial statements listed in Schedule
3.06 or the most recently delivered financial statements delivered in accordance
with Section 5.20, since September 30, 1999, there has been no change in the
financial condition, operations, business, properties or prospects of the
Borrower or any of its Subsidiaries except changes that individually or in the
aggregate would not reasonably be expected to have a Material Adverse Effect.
There is no fact known to the Borrower that could reasonably be expected to have
a Material Adverse Effect that has not been set forth herein or in the financial
statements listed in Schedule 3.06.

         SECTION 3.07. Litigation; Observance of Statutes and Orders.

         (a) There are no actions, suits or proceedings pending or, to the
knowledge of the Borrower, threatened against or affecting the Borrower or any
Subsidiary or any property of the Borrower or any Subsidiary in any court or
before any arbitrator of any kind or before or by any Applicable Governmental
Authority that, individually or in the aggregate, would reasonably be expected
to have a Material Adverse Effect.

         (b) Neither the Borrower nor any Subsidiary is in default under any
agreement or instrument to which it is a party or by which it is bound, or any
order, judgment, decree or ruling of any court, arbitrator or Applicable
Governmental Authority or is in violation of any applicable law, ordinance, rule
or regulation (including without limitation Environmental Laws) of any
Applicable Governmental Authority, which default or violation, individually or
in the aggregate, would reasonably be expected to have a Material Adverse
Effect.

         SECTION 3.08. Taxes. The Borrower and its Subsidiaries have filed all
income tax returns that are required to have been filed in any jurisdiction, and
have paid all taxes shown to be due and payable on such returns and all other
taxes and assessments payable by them, to the extent such taxes and assessments
have become due and payable and before they have become delinquent, except for
any taxes and assessments (i) the amount of which is not individually or in the
aggregate Material or (ii) the amount, applicability or validity of which is
currently being contested in good faith by appropriate proceedings and with
respect to which the Borrower or a Subsidiary, as the case may be, has
established adequate reserves in accordance with GAAP. The Federal income tax
liabilities of the Borrower and its Subsidiaries have been determined by the
Internal Revenue Service and paid for all fiscal years up to and including the
fiscal year ended December 31, 1995.

         SECTION 3.09. Title to Property; Leases. The Borrower and its
Subsidiaries have good and sufficient title to their respective Material
properties, including all such properties reflected in the most recent audited
balance sheet referred to in Section 3.06 or purported to have been acquired by
the Borrower or any Subsidiary after said date (except as sold or otherwise
disposed of in the ordinary course of business), in each case free and clear of
Liens prohibited by this Agreement, except for those defects in title and Liens
that, individually or in the aggregate, would not have a Material Adverse
Effect. All Material leases are valid and subsisting and are in full force and
effect in all material respects.


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 33


<PAGE>   38
         SECTION 3.10. Licenses, Permits, etc. The Borrower and its Subsidiaries
own or possess all licenses, permits, franchises, authorizations, patents,
copyrights, service marks, trademarks and trade names, or rights thereto, that
are Material, without known conflict with the rights of others, except for those
conflicts that, individually or in the aggregate, would not have a Material
Adverse Effect.

         SECTION 3.11. Compliance with ERISA.

         (a) The Borrower and each ERISA Affiliate have operated and
administered each Plan in compliance with all applicable laws except for such
instances of noncompliance as have not resulted in and could not reasonably be
expected to result in a Material Adverse Effect. Neither the Borrower nor any
ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or
the penalty or excise tax provisions of the Code relating to employee benefit
plans (as defined in Section 3 of ERISA), and no event, transaction or condition
has occurred or exists that would reasonably be expected to result in the
incurrence of any such liability by the Borrower or any ERISA Affiliate, or in
the imposition of any Lien on any of the rights, properties or assets of the
Borrower or any ERISA Affiliate, in either case pursuant to Title I or IV of
ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or
412 of the Code, other than such liabilities or Liens as would not be
individually or in the aggregate Material.

         (b) The present value of the aggregate accrued plan benefit liabilities
under each of the Plans that are subject to Title IV of ERISA (other than
Multiemployer Plans), determined in accordance with Financial Accounting
Standards Board Statement No. 87 as of the end of such Plan's most recently
ended plan year on the basis of the actuarial assumptions specified for funding
purposes in such Plan's most recent actuarial valuation report, did not exceed
the aggregate current value of the assets of such Plan allocable to such benefit
liabilities by more than $3,000,000 in the case of any single Plan and by more
than $3,000,000 in the aggregate for all Plans.

         (c) The Borrower and its ERISA Affiliates have not incurred withdrawal
liabilities (and are not subject to contingent withdrawal liabilities) under
section 4201 or 4204 of ERISA in respect of Multiemployer Plans that
individually or in the aggregate are Material.

         (d) The expected post-retirement benefit obligation (determined as of
the last day of the Borrower's most recently ended fiscal year in accordance
with Financial Accounting Standards Board Statement No. 106, without regard to
liabilities attributable to continuation coverage mandated by section 4980B of
the Code) of the Borrower and its Subsidiaries was approximately $17,955,591 as
of December 31, 1998.

         SECTION 3.12. Use of Proceeds; Margin Regulation. The Borrower will
apply the proceeds of the Borrowings to make acquisitions, for capital
expenditures, for working capital and for other general corporate purposes. The
Letters of Credit shall be issued to support transactions of the Borrower and
the Subsidiaries entered into in the ordinary course of business. No part of the
proceeds from the Borrowings will be used, directly or indirectly, for the
purpose of buying or carrying any margin stock within the meaning of Regulation
U of the Board (12 CFR 221), or for the purpose of buying or carrying or trading
in any securities under such circumstances as to involve the Borrower in a
violation of Regulation X of the Board (12 CFR 224) or to involve any broker or
dealer in a violation of Regulation T of the Board (12 CFR 220). Margin stock
does not constitute more than 5% of the value of the consolidated assets of the
Borrower and its Restricted Subsidiaries and the Borrower does not have any
present intention that margin stock will constitute more than 5% of the value of
such assets. As used in this Section, the terms "margin stock" and "purpose of
buying or carrying" shall have the meanings assigned to them in said Regulation
U.


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 34


<PAGE>   39
         SECTION 3.13. Existing Indebtedness. Except as described therein,
Schedule 3.13 sets forth a complete and correct list of all outstanding
Indebtedness of the Borrower and its Restricted Subsidiaries (other than
Indebtedness of Restricted Subsidiaries to the Borrower or to Wholly-Owned
Restricted Subsidiaries) as of December 31, 1999, since which date there has
been no Material change in the amounts, interest rates, sinking funds,
installment payments or maturities of the Indebtedness of the Borrower or its
Restricted Subsidiaries. Neither the Borrower nor any Restricted Subsidiary is
in default, and no waiver of default is currently in effect, in the payment of
any principal or interest on any Indebtedness of the Borrower or such Restricted
Subsidiary, and no event or condition exists with respect to any Indebtedness of
the Borrower or any Restricted Subsidiary the outstanding principal amount of
which exceeds $3,000,000 in the aggregate that would permit (or that with notice
or the lapse of time, or both, would permit) one or more Persons to cause such
Indebtedness to become due and payable before its stated maturity or before its
regularly scheduled dates of payment. To the knowledge of the Responsible
Officers of the Borrower, no event or condition exists with respect to any
Indebtedness of the Borrower or any Restricted Subsidiary that would permit (or
that with notice or the lapse of time, or both, would permit) one or more
Persons to cause such Indebtedness to become due and payable before its stated
maturity or before its regularly scheduled dates of payment.

         SECTION 3.14. Foreign Assets Control Regulations, etc. The use of the
proceeds of the Borrowings will not violate the Trading with the Enemy Act, as
amended, or any of the foreign assets control regulations of the United States
Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling
legislation or executive order relating thereto.

         SECTION 3.15. Status under Certain Statutes. Neither the Borrower nor
any Subsidiary is subject to regulation under the Investment Company Act of
1940, as amended, the Public Utility Holding Company Act of 1935, as amended,
the Interstate Commerce Act, as amended, or the Federal Power Act, as amended.

         SECTION 3.16. No Material Misstatements. No report, financial statement
or other information furnished by or on behalf of the Borrower to the
Administrative Agent or any Lender pursuant to or in connection with this
Agreement contains or will contain any material misstatement of fact or omits or
will omit to state any material fact necessary to make the statements therein,
in the light of the circumstances under which they were or will be made, not
misleading.

         SECTION 3.17. Year 2000 Matters. Any programming required to permit the
proper functioning, in and following the year 2000, of the Borrower's and its
Subsidiaries' Material (i) computer systems and (ii) equipment containing
imbedded microchips (including systems and equipment supplied by others or with
which the Borrower's or its Subsidiaries' systems interface) and the testing of
all such systems and equipment, as so reprogrammed has been completed. The cost
to the Borrower and its Subsidiaries of such reprogramming and testing and of
the reasonably foreseeable consequences of year 2000 to the Borrower and its
Subsidiaries (including, without limitation, reprogramming errors and the
failure of others' systems or equipment) has not resulted in a Default or a
Material Adverse Effect. The computer and management information systems of the
Borrower and its Subsidiaries are, and with ordinary course upgrading and
maintenance, will continue for the term of this Agreement to be, sufficient to
permit the Borrower and its Subsidiaries to conduct its business without
Material Adverse Effect.

                                   ARTICLE 5.

                       AFFIRMATIVE AND NEGATIVE COVENANTS

         The Borrower agrees that, so long as any Lender has any Commitment
hereunder or any obligation to acquire or fund any participation in any
Swingline Loan or Letter of Credit or the Swingline Lender is obligated to make
Swingline Loans or the Issuing Bank is obligated to issue any Letter of Credit,
or any amount payable hereunder remains unpaid:

         SECTION 5.01. Compliance with Laws. The Borrower will and will cause
each of its Subsidiaries to comply with all laws, ordinances or governmental
rules or regulations to which each of them is subject, including, without
limitation, Environmental Laws, and will obtain and maintain in effect all
licenses, certificates, permits, franchises and other governmental
authorizations necessary to the ownership of their respective properties or to
the conduct of their respective businesses, in each case to the extent necessary
to ensure that non-compliance with such laws, ordinances or governmental rules
or regulations or failures to obtain or maintain in effect such licenses,
certificates, permits, franchises and other governmental authorizations would
not reasonably be expected, individually or in the aggregate, to have a material
adverse effect on the business, operations, affairs, financial condition,
properties or assets of the Borrower and its Restricted Subsidiaries taken as a
whole.

         SECTION 5.02. Insurance. The Borrower will and will cause each of its
Subsidiaries to maintain, with financially sound and reputable insurers,
insurance with respect to their respective properties and businesses against
such casualties and contingencies, of such types, on such terms and in such
amounts (including deductibles, co-insurance and self-insurance, if adequate
reserves are maintained with respect thereto) as is customary in the case of
entities of established reputations engaged in the same or a similar business
and similarly situated.

         SECTION 5.03. Maintenance of Properties and Lines of Business. The
Borrower will and will cause each of its Subsidiaries to maintain and keep, or
cause to be maintained and kept, their respective properties in good repair,
working order and condition (other than ordinary wear and tear), so that the
business carried on in connection therewith may be properly conducted at all
times, provided that this Section shall not prevent the Borrower or any
Subsidiary from discontinuing the operation and the maintenance of any of its
properties if such discontinuance is desirable in the conduct of its business
and the Borrower has concluded that such discontinuance would not, individually
or in the aggregate, have a materially adverse effect on the business,
operations, affairs, financial condition, properties or assets of the Borrower
and its Restricted Subsidiaries taken as a whole. The Borrower will not and will
not permit any of its Restricted Subsidiaries to engage in any line of business
other than such lines of business in which it is presently engaged and those
businesses reasonably related thereto.

         SECTION 5.04. Payment of Taxes. The Borrower will and will cause each
of its Subsidiaries to file all income tax or similar tax returns required to be
filed in any jurisdiction and to pay and discharge all taxes shown to be due and
payable on such returns and all other taxes, assessments, governmental charges,


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 37


<PAGE>   42
or levies payable by any of them, to the extent such taxes and assessments have
become due and payable and before they have become delinquent, provided that
neither the Borrower nor any Subsidiary need pay any such tax or assessment if
(i) the amount, applicability or validity thereof is contested by the Borrower
or such Subsidiary on a timely basis in good faith and in appropriate
proceedings, and the Borrower or a Subsidiary has established adequate reserves
therefor in accordance with GAAP on the books of the Borrower or such Subsidiary
or (ii) the nonpayment of all such taxes and assessments in the aggregate would
not reasonably be expected to have a materially adverse effect on the business,
operations, affairs, financial condition, properties or assets of the Borrower
and its Restricted Subsidiaries taken as a whole.

         SECTION 5.05. Corporate Existence, etc. The Borrower will at all times
preserve and keep in full force and effect its corporate existence. Subject to
Sections 5.10 and 5.11, the Borrower will at all times preserve and keep in full
force and effect the corporate existence of each of its Restricted Subsidiaries
(unless merged into the Borrower or a Restricted Subsidiary) and all rights and
franchises of the Borrower and its Restricted Subsidiaries unless, in the good
faith judgment of the Borrower, the termination of or failure to preserve and
keep in full force and effect such corporate existence, right or franchise would
not, individually or in the aggregate, have a Material Adverse Effect on the
business, operations, affairs, financial condition, properties or assets of the
Borrower and its Restricted Subsidiaries taken as a whole.

         SECTION 5.06. Most Favored Lender Status. The Borrower will not and
will not permit any Restricted Subsidiary to enter into, assume or otherwise be
bound or obligated under any agreement creating or evidencing Indebtedness or
any agreement executed and delivered in connection with any Indebtedness
containing one or more Additional Covenants or Additional Defaults (as defined
below), unless prior written consent to such agreement shall have been obtained
from the Required Lenders; provided, however, in the event the Borrower or any
Restricted Subsidiary shall enter into, assume or otherwise become bound by or
obligated under any such agreement without the prior written consent of the
Required Lenders, the terms of this Agreement shall, without any further action
on the part of the Borrower or any of the Lenders, be deemed to be amended
automatically to include each Additional Covenant and each Additional Default
contained in such agreement. The Borrower further covenants to promptly execute
and deliver at its expense an amendment to this Agreement in form and substance
satisfactory to the Required Lenders evidencing the amendment of this Agreement
to include such Additional Covenants and Additional Defaults, provided that the
execution and delivery of such amendment shall not be a precondition to the
effectiveness of such amendment as provided for in this Section 5.06, but shall
merely be for the convenience of the parties hereto.

         For purposes of this Agreement, (i) the term "Additional Covenant"
shall mean any affirmative or negative covenant or similar restriction
applicable to the Borrower or any Restricted Subsidiary (regardless of whether
such provision is labeled or otherwise characterized as a covenant) the subject
matter of which either (A) is similar to that of the covenants in Article 5 of
this Agreement, but contains one or more percentages, amounts or formulas that
is more restrictive than those set forth herein or more beneficial to the holder
or holders of such other Indebtedness (and such covenant or similar restriction
shall be deemed an "Additional Covenant" only to the extent that it is more
restrictive or more beneficial) or (B) is different from the subject matter of
the covenants in Article 5 of this Agreement; and (ii) the term "Additional
Default" shall mean any provision which permits the holder of such Indebtedness
to accelerate (with the passage of time or giving of notice or both) the
maturity thereof or otherwise require the Borrower or any Restricted Subsidiary
to purchase such Indebtedness prior to the stated maturity of such Indebtedness
and which either (A) is similar to the Defaults and Events of Default contained
in Article 6 of this Agreement, but contains one or more percentages, amounts or
formulas that is more restrictive or has a shorter grace period than those set
forth herein or is more beneficial to the holder or holders of such other
Indebtedness (and such provision shall be deemed an "Additional Default" only to
the extent that it is more restrictive, has


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 38


<PAGE>   43
a shorter grace period or is more beneficial) or (B) is different from the
subject matter of the Defaults and Events of Default contained in Article 6 of
this Agreement.

         SECTION 5.07. Covenant to Secure Loans Equally. If the Borrower shall
create, assume or permit to exist any Lien upon any of its property or assets,
or permit any Restricted Subsidiary to create, assume or permit to exist any
Lien upon any of its property or assets, whether now owned or hereafter
acquired, other than those Liens permitted by the provisions of Section 5.13,
the Borrower shall make or cause to be made effective provision whereby the
Borrowings will be secured equally and ratably with any and all other
obligations thereby secured, with the documentation for such security to be
reasonably satisfactory to the Required Lenders and, in any such case, the
Borrowings shall have the benefit, to the fullest extent that, and with such
priority as, the holders thereof may be entitled under applicable law, of an
equitable Lien on such property. Any violation of Section 5.13 will constitute
an Event of Default, whether or not provision is made for an equal and ratable
Lien pursuant to this Section 5.07.

         SECTION 5.08. Environmental Matters.

         (a) The Borrower will and will cause each of its Subsidiaries to comply
in all material respects with all applicable Environmental Laws if, individually
or in the aggregate, failure to comply therewith could reasonably be expected to
have a material adverse effect on the financial condition or results of
operations of the Borrower or the Borrower and its Subsidiaries, taken as a
whole.

         (b) The Borrower will not and will not permit any of its Subsidiaries
to cause or allow any Hazardous Substance to be present at any time on, in,
under or above any real property or any part thereof in which the Borrower or
any Subsidiary has a direct interest (including without limitation ownership
thereof or any arrangement for the lease, rental or other use thereof, or the
retention of any mortgage or security interest therein or thereon), except in a
manner and to an extent that is in compliance in all material respects with all
applicable Environmental Laws or that will not have a material adverse effect on
the financial condition or results of operations of the Borrower or the Borrower
and its Subsidiaries, taken as a whole.

         SECTION 5.09. Transactions with Affiliates. The Borrower will not
permit any Restricted Subsidiary to enter into directly or indirectly any
Material transaction or Material group of related transactions (including
without limitation the purchase, lease, sale or exchange of properties of any
kind or the rendering of any service) with any Affiliate (other than the
Borrower or another Restricted Subsidiary), except pursuant to the reasonable
requirements of the Borrower's or such Restricted Subsidiary's business and upon
fair and reasonable terms no less favorable to the Borrower or such Restricted
Subsidiary than would be obtainable in a comparable arm's-length transaction
with a Person not an Affiliate.

         SECTION 5.10. Merger, Consolidation, etc. The Borrower will not
consolidate with or merge with any other corporation or convey, transfer or
lease substantially all of its assets in a single transaction or series of
transactions to any Person unless:

         (a) the successor formed by such consolidation or the survivor of such
merger or the Person that acquires by conveyance, transfer or lease
substantially all of the assets of the Borrower as an entirety, as the case may
be, shall be a solvent corporation organized and existing under the laws of the
United States or any State thereof (including the District of Columbia), and, if
the Borrower is not such corporation, such corporation shall have executed and
delivered to each Lender its assumption of the due and punctual performance and
observance of each covenant and condition of this Agreement, together with a
favorable opinion of counsel satisfactory to each such Lender covering such
matters relating to such corporation and such assumption as such Lender may
reasonably request; and

         (b) immediately after giving effect to such transaction, no Default or
Event of Default would exist; and

         (c) immediately prior to and after giving effect to such transaction,
the Borrower or such successor, as the case may be, would be permitted by the
provisions of Sections 5.12 and 5.17 to incur at least $1.00 of additional
Indebtedness and $1.00 of additional Restricted Indebtedness, respectively.

         No such conveyance, transfer or lease of substantially all of the
assets of the Borrower shall have the effect of releasing the Borrower or any
successor corporation that shall theretofore have become such in the manner
prescribed in this Section 5.10 from its liability under this Agreement.

         SECTION 5.11. Sale of Assets, etc. The Borrower will not, and will not
permit any of its Restricted Subsidiaries to, make any Transfer, provided that
the foregoing restriction does not apply to a Transfer if:

         (a) the property that is the subject of such Transfer constitutes
either (i) inventory held for sale, or (ii) equipment, fixtures, supplies or
materials no longer required in the operation of the business of the Borrower or
such Restricted Subsidiary or that is obsolete, and, in the case of any Transfer
described in clause (i) or (ii), such Transfer is in the ordinary course of
business (each such Transfer, an "Ordinary Course Transfer"); or

         (b) such Transfer is from

                           (i) a Restricted Subsidiary to the Borrower or
                  another Restricted Subsidiary, or

                           (ii) the Borrower to a Restricted Subsidiary, or

                           (iii) the Borrower to a Subsidiary (other than a
                  Restricted Subsidiary) or from a Restricted Subsidiary to
                  another Subsidiary (other than a Restricted Subsidiary) and in
                  either case is for Fair Market Value, so long as immediately
                  before and immediately after the consummation of such
                  transaction, and after giving effect thereto, no Default or
                  Event of Default exists or would exist (each such Transfer, an
                  "Intergroup Transfer"); or

         (c) such Transfer is not an Ordinary Course Transfer or an Intergroup
Transfer (such Transfers which are not Ordinary Course Transfers or Intergroup
Transfers collectively referred to as "Excluded Transfers"), and all of the
following conditions shall have been satisfied with respect thereto (the date of
the consummation of such Transfer being referred to herein as the "Property
Disposition Date"):

                           (i) the book value of the assets included in such
                  Transfer, together with the book value of the assets included
                  in all other Transfers (other than Excluded Transfers) during
                  the fiscal year which includes the Property Disposition Date,
                  shall not exceed fifteen percent (15%) of Consolidated Assets
                  as of the end of the most recent fiscal year;


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 40


<PAGE>   45
                           (ii) the book value of the assets included in such
                  Transfer, together with the book value of the assets included
                  in all other Transfers (other than Excluded Transfers) from
                  the Effective Date through the Property Disposition Date,
                  shall not exceed thirty percent (30%) of Consolidated Assets
                  as of the end of the most recent fiscal year; and

                           (iii) immediately after giving effect to such
                  Transfer, no Default or Event of Default would exist and the
                  Borrower would be permitted by the provisions of Sections 5.12
                  and 5.17 to incur at least $1.00 of additional Indebtedness
                  and $1.00 of additional Restricted Indebtedness, respectively.

         If, within twelve (12) months after the Property Disposition Date, the
Borrower or a Restricted Subsidiary acquires assets similar to the assets
included in the Transfer, then, only for the purpose of determining compliance
with Sections 5.11(c)(i) and (ii), the lesser of the book value of the assets
acquired or the book value of the assets included in the Transfer shall not be
taken into account.

         SECTION 5.12. Incurrence of Indebtedness. The Borrower will not, and
will not permit any Restricted Subsidiary to, directly or indirectly, create,
incur, assume, guarantee, or otherwise become directly or indirectly liable with
respect to any Indebtedness, unless on the date the Borrower or such Restricted
Subsidiary becomes liable with respect to any such Indebtedness and immediately
after giving effect thereto and to the substantially concurrent retirement of
any other Indebtedness,

         (a) no Default or Event of Default would exist, and

         (b) Consolidated Indebtedness would not exceed sixty percent (60%) of
Consolidated Capitalization.

         For purposes of this Section 5.12 any Person becoming a Restricted
Subsidiary after the date of this Agreement shall be deemed to have incurred all
of its then outstanding Indebtedness at the time it becomes a Restricted
Subsidiary.

         SECTION 5.13. Liens. The Borrower will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly create, incur, assume or
permit to exist (upon the happening of a contingency or otherwise) any Lien on
or with respect to any property or asset (including, without limitation, any

similar obligations, in each case not incurred or made in connection with the
borrowing of money, the obtaining of advances or credit or the payment of the
deferred purchase price of property;

         (d) any attachment or judgment Lien, unless the judgment or other
obligation it secures (i) shall not, within ninety (90) days after the entry
thereof, have been discharged or execution thereof stayed pending appeal, or
shall not have been discharged within ninety (90) days after the expiration of
any such stay or (ii) exceeds, together with the amounts of all other

         (e) leases or subleases granted to others, easements, rights-of-way,
restrictions and other similar charges or encumbrances, in each case incidental
to, and not interfering with, the ordinary conduct of the business of the
Borrower or any of its Restricted Subsidiaries, provided that such Liens do not,
in the aggregate, materially detract from the value of such property;

         (f) Liens on property or assets of the Borrower or any of its
Restricted Subsidiaries securing Indebtedness or other obligations owing to the
Borrower or to a Wholly Owned Restricted Subsidiary; and

above, provided that (i) the fair market value of the assets subject to such
other Liens shall not exceed 15% of Consolidated Net Worth and (ii) immediately
after giving effect to the creation thereof, the Borrower would be permitted by
the provisions of Sections 5.12 and 5.17 to incur at least $1.00 of additional
Indebtedness and $1.00 of additional Restricted Indebtedness, respectively.

         For purposes of this Section 5.13, any Person becoming a Restricted
Subsidiary after the date of this Agreement shall be deemed to have incurred all
of its then outstanding Liens at the time it becomes a Restricted Subsidiary,
and any Person extending, renewing or refunding any Indebtedness secured by any
Lien shall be deemed to have incurred such Lien at the time of such extension,
renewal or refunding.

         SECTION 5.14. Restricted Payments. The Borrower will not, and will not
permit any of its Restricted Subsidiaries to, declare or make, or incur any
liability to declare or make, any Restricted Payment, unless immediately after
giving effect to such action:

         (a) no Default or Event of Default would exist; and

                  interest expenses (including the interest portion of Capital
                  Leases) for the Borrower and the Restricted Subsidiaries
                  calculated on a consolidated basis without duplication in
                  accordance with GAAP.

         (b) Consolidated Indebtedness to Adjusted EBITDA. As of the last day of
each fiscal quarter during the periods described below, the Borrower shall not
permit the ratio of Consolidated Indebtedness outstanding as of such day to the
Adjusted EBITDA for the four (4) fiscal quarters then ended to exceed: (i) 3.00
to 1.00 at all times other than as described in the following clause (ii); or
(ii) 3.25 to 1.00 for all fiscal quarters ending prior to March 31, 2001 if, and
only if prior to any such fiscal quarter end Borrower shall have delivered to
the Administrative Agent evidence satisfactory to it that the holders of the
Indebtedness outstanding under the Senior Note Purchase Agreements and the
holders of any other Indebtedness that have the benefit of a Consolidated
Indebtedness to Adjusted EBITDA ratio the same or similar to this Section
5.15(b), shall have agreed to a maximum ratio not to exceed 3.25 to 1.00 for all
fiscal quarters prior to March 31, 2001.

Net Worth as at the last day of any fiscal quarter of the Borrower to be less
than the sum of (a) $261,000,000, plus (b) 15% of its aggregate Consolidated Net

Distributions in respect of the capital stock of such Restricted Subsidiary to
the Borrower or another Restricted Subsidiary.

         SECTION 5.17. Limitation on Restricted Indebtedness. The Borrower will
not at any time permit the aggregate amount of Restricted Indebtedness to exceed
15% of Consolidated Net Worth.

         SECTION 5.18. Preferred Stock of Restricted Subsidiaries. The Borrower
will not permit any Restricted Subsidiary to issue or permit to remain
outstanding any Preferred Stock unless such Preferred Stock is issued to and at
all times owned and held by the Borrower or a Wholly-Owned Restricted
Subsidiary.

         SECTION 5.19. No Redesignation of Restricted Subsidiaries. The Borrower
will not designate any Restricted Subsidiary as, or take or permit to be taken
any action that would cause any Restricted Subsidiary to become, an Unrestricted
Subsidiary.

other instruments or agreements; provided that the foregoing exclusion shall not
have the effect of releasing the Administrative Agent from its stated

in connection herewith. The Administrative Agent may execute any and all duties
hereunder by or through agents or employees and shall be entitled to rely upon
the advice of legal counsel selected by it with respect to all matters arising
hereunder and shall not be liable for any action taken or suffered in good faith
by it in accordance with the advice of such counsel.

         The Lenders and the Issuing Bank hereby acknowledge that the
Administrative Agent shall be under no duty to take any discretionary action
permitted to be taken by it pursuant to the provisions of this Agreement unless

Administrative Agent, in its individual capacity as a Lender and the Swingline
Lender and not as Administrative Agent shall have the same rights and powers as
any other Lender and may exercise the same as though it were not the
Administrative Agent, and the Administrative Agent and its Affiliates may accept
deposits from, lend money to and generally engage in any kind of business with
the Borrower or any Subsidiary or other Affiliate thereof as if it were not the
Administrative Agent.

         Each Lender agrees (i) to reimburse the Administrative Agent, on
demand, in the amount of its Applicable Percentage of any expenses incurred for

NEGLIGENCE OF THE ADMINISTRATIVE AGENT); PROVIDED THAT NO LENDER SHALL BE LIABLE
TO THE ADMINISTRATIVE AGENT FOR ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS,
LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR
DISBURSEMENTS RESULTING FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE

or document furnished pursuant hereto or the financial condition of the Borrower
or the performance or observance by the Borrower of any obligations under this
Agreement or any other instrument or document furnished pursuant hereto; (iii)
such assignee represents and warrants that it is legally authorized to enter
into such Assignment and Acceptance; (iv) such assignee confirms that it has
received a copy of this Agreement, together with copies of the most recent
financial statements delivered pursuant to Section 5.20 and such other documents
and information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (v) such assignee will
independently and without reliance upon the Administrative Agent, such assigning
Lender or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement; (vi) such assignee appoints
and authorizes the Administrative Agent to take such action as agent on its
behalf and to exercise such powers under this Agreement as are delegated to the
Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto; and (vii) such assignee agrees that it will
perform in accordance with their terms all the obligations which by the terms of
this Agreement are required to be performed by it as a Lender.

         (d) The Administrative Agent shall maintain at one of its offices in
New York, New York a copy of each Assignment and Acceptance delivered to it and
a register for the recordation of the names and addresses of the Lenders, and
the Commitment of, the principal amount of the Loans and Swingline Loans owing
to and the participations interest in Letters of Credit held by, each Lender
pursuant to the terms hereof from time to time (the "Register"). The entries in
the Register shall be conclusive in the absence of manifest error and the
Borrower, the Administrative Agent and the Lenders may treat each Person whose
name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement. The Register shall be available
for inspection by each party hereto, at any reasonable time and from time to
time upon reasonable prior notice.

         (e) Upon its receipt of a duly completed Assignment and Acceptance

Administrative Agent sell participations to one or more banks or other entities
in all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans owing to it);
provided, however, that (i) such Lender's obligations under this Agreement shall
remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) each participating
bank or other entity shall be entitled to the benefit of the cost protection
provisions contained in Sections 2.11, 2.16 and 8.05 to the same extent as if it
were the selling Lender (and limited to the amount that could have been claimed
by the selling Lender had it continued to hold the interest of such
participating bank or other entity), except that all claims made pursuant to
such Sections shall be made through such selling Lender, and (iv) the Borrower,
the Administrative Agent, and the other Lenders shall continue to deal solely
and directly with such selling Lender in connection with such Lender's rights
and obligations under this Agreement. Any agreement or instrument pursuant to
which a Lender sells such a participation shall provide that such Lender shall
retain the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the
consent of the participant, agree to any amendment, modification or waiver
described in clauses (i) through (iii) of Section 8.08(b) that affects such
participant.

<PAGE>   59
         (g) Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section,
disclose to the assignee or participant or proposed assignee or participant any
information relating to the Borrower furnished to such Lender by or on behalf of
the Borrower; provided that, prior to any such disclosure, each such assignee or
participant or proposed assignee or participant shall execute an agreement
whereby such assignee or participant shall agree (subject to customary
exceptions) to preserve the confidentiality of any such information which
constitutes Confidential Information in accordance with Section 8.14.

         (h) The Borrower shall not assign or delegate any rights and duties
hereunder without the prior written consent of all Lenders, and any attempted
assignment or delegation (except as a consequence of a transaction expressly
permitted under Section 5.10) by the Borrower without such consent shall be
void.

         (i) Any Lender may at any time assign or pledge all or any portion of
its rights under this Agreement to a Federal Reserve Bank; provided that no such
assignment or pledge shall release any Lender from its obligations hereunder or
substitute any such Federal Reserve Bank for such Lender as a party hereto. In
order to facilitate such an assignment to a Federal Reserve Bank, the Borrower
shall, at the request of the assigning Lender, duly execute and deliver to the
assigning Lender a promissory note or notes evidencing the Loans and Swingline
Loans made to the Borrower by the assigning Lender hereunder.

         SECTION 8.05. Expenses; Indemnity.

         (a) The Borrower agrees to pay all reasonable out-of-pocket expenses
incurred by Administrative Agent or Chase Securities Inc. or the Issuing Bank in
connection with entering into this Agreement or in connection with any
amendments, modifications or waivers of the provisions hereof (but only if such
amendments, modifications or waivers are requested by the Borrower) (whether or
not the transactions hereby contemplated are consummated) or in connection with
the issuance, modification, extension or renewal of any Letter of Credit, or
incurred by the Administrative Agent, the Issuing Bank, or any Lender in
connection with the enforcement of their rights in connection with this
Agreement or in connection with the Loans and Swingline Loans made and Letters
of Credit issued hereunder, including the reasonable fees and disbursements of
counsel for the Administrative Agent and the Issuing Bank or, in the case of
enforcement following an Event of Default, the Lenders.

         (b) THE BORROWER AGREES TO INDEMNIFY EACH LENDER AND ISSUING BANK
AGAINST ANY LOSS, CALCULATED IN ACCORDANCE WITH THE NEXT SENTENCE, OR REASONABLE
EXPENSE WHICH SUCH LENDER OR ISSUING BANK MAY SUSTAIN OR INCUR AS A CONSEQUENCE
OF (A) ANY FAILURE BY THE BORROWER TO BORROW OR TO CONVERT OR CONTINUE ANY LOAN
OR SWINGLINE LOAN HEREUNDER (INCLUDING AS A RESULT OF THE BORROWER'S FAILURE TO
FULFILL ANY OF THE APPLICABLE CONDITIONS SET FORTH IN ARTICLE 4) AFTER
IRREVOCABLE NOTICE OF SUCH BORROWING, CONVERSION OR CONTINUATION HAS BEEN GIVEN
PURSUANT HERETO, (B) ANY PAYMENT, PREPAYMENT OR CONVERSION, ASSIGNMENT OR
FUNDING OF A EURODOLLAR LOAN OR NEGOTIATED RATE BORROWING REQUIRED BY ANY
PROVISION OF THIS AGREEMENT OR OTHERWISE MADE OR DEEMED MADE ON A DATE OTHER
THAN THE LAST DAY OF THE INTEREST PERIOD, IF ANY, APPLICABLE THERETO, (INCLUDING
ANY FUNDING OF A EURODOLLAR LOAN OR NEGOTIATED RATE BORROWING AS A RESULT OF THE
OPERATION OF SECTION 2.19(b)) (C) ANY DEFAULT IN PAYMENT OR PREPAYMENT OF THE
PRINCIPAL AMOUNT OF ANY LOAN OR SWINGLINE LOAN OR ANY REIMBURSEMENT OBLIGATION
IN RESPECT OF ANY LC DISBURSEMENT OR ANY PART THEREOF OR INTEREST ACCRUED
THEREON, AS AND WHEN DUE AND PAYABLE (AT THE DUE DATE THEREOF, WHETHER BY
SCHEDULED MATURITY,


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 55


<PAGE>   60
ACCELERATION, IRREVOCABLE NOTICE OF PREPAYMENT OR OTHERWISE) OR (D) THE
OCCURRENCE OF ANY EVENT OF DEFAULT, INCLUDING, IN EACH SUCH CASE, ANY LOSS OR
REASONABLE EXPENSE SUSTAINED OR INCURRED OR TO BE SUSTAINED OR INCURRED BY SUCH
LENDER IN LIQUIDATING OR EMPLOYING DEPOSITS FROM THIRD PARTIES, OR WITH RESPECT
TO COMMITMENTS MADE OR OBLIGATIONS UNDERTAKEN WITH THIRD PARTIES, TO EFFECT OR
MAINTAIN ANY LOAN OR SWINGLINE LOAN HEREUNDER OR ANY PART THEREOF AS A
EURODOLLAR LOAN OR NEGOTIATED RATE BORROWING. SUCH LOSS SHALL INCLUDE AN AMOUNT
EQUAL TO THE EXCESS, IF ANY, AS REASONABLY DETERMINED BY SUCH LENDER, OF (I) ITS
COST OF OBTAINING THE FUNDS FOR THE LOAN OR SWINGLINE LOAN BEING PAID, PREPAID,
CONVERTED OR NOT BORROWED (ASSUMED TO BE THE LIBO RATE OR WITH RESPECT TO THE
NEGOTIATED RATE BORROWINGS, THE APPLICABLE NEGOTIATED RATE) FOR THE PERIOD FROM
THE DATE OF SUCH PAYMENT, PREPAYMENT OR FAILURE TO BORROW TO THE LAST DAY OF THE
INTEREST PERIOD FOR SUCH LOAN OR SWINGLINE LOAN (OR, IN THE CASE OF A FAILURE TO
BORROW THE INTEREST PERIOD FOR SUCH LOAN OR SWINGLINE LOAN WHICH WOULD HAVE
COMMENCED ON THE DATE OF SUCH FAILURE) OVER (II) THE AMOUNT OF INTEREST (AS
REASONABLY DETERMINED BY SUCH LENDER) THAT WOULD BE REALIZED BY SUCH LENDER IN
REEMPLOYING THE FUNDS SO PAID, PREPAID OR NOT BORROWED FOR SUCH PERIOD OR
INTEREST PERIOD, AS THE CASE MAY BE.

         (c) THE BORROWER AGREES TO INDEMNIFY THE ADMINISTRATIVE AGENT, THE
ISSUING BANK, EACH LENDER, EACH OF THEIR AFFILIATES AND THE DIRECTORS, OFFICERS,
EMPLOYEES AND AGENTS OF THE FOREGOING (EACH SUCH PERSON BEING CALLED AN
"INDEMNITEE") AGAINST, AND TO HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL
LOSSES, CLAIMS, DAMAGES, LIABILITIES AND RELATED EXPENSES, INCLUDING REASONABLE
COUNSEL FEES AND EXPENSES, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE
ARISING OUT OF (I) THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED BY THIS
AGREEMENT, (II) THE USE OF THE PROCEEDS OF THE BORROWINGS OR THE USE OF ANY
LETTER OF CREDIT OR (III) ANY CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING
RELATING TO ANY OF THE FOREGOING, WHETHER OR NOT ANY INDEMNITEE IS A PARTY
THERETO (INCLUDING, WITHOUT LIMITATION, ANY LOSSES, CLAIMS, DAMAGES, LIABILITIES
AND RELATED EXPENSES ARISING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF THE
INDEMNITEE); PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE
AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR
RELATED EXPENSES (I) ARE DETERMINED TO HAVE RESULTED FROM THE GROSS NEGLIGENCE
OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE OR (II) RESULT FROM ANY LITIGATION
BROUGHT BY SUCH INDEMNITEE AGAINST THE BORROWER OR BY THE BORROWER AGAINST SUCH
INDEMNITEE, IN WHICH THE BORROWER IS THE PREVAILING PARTY.

         (d) The provisions of this Section shall remain operative and in full
force and effect regardless of the expiration of the term of this Agreement, the
termination or satisfaction of all Letter of Credit Liabilities, the
consummation of the transactions contemplated hereby, the repayment of any of
the Borrowings, the invalidity or unenforceability of any term or provision of
this Agreement or any investigation made by or on behalf of any Agent or any
Lender. All amounts due under this Section shall be payable on written demand
therefor.

         SECTION 8.06. Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law,


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 56


<PAGE>   61
to set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by such Lender to or for the credit or the account of the Borrower against any
of and all the obligations of the Borrower now or hereafter existing under this
Agreement held by such Lender, irrespective of whether or not such Lender shall
have made any demand under this Agreement and although such obligations may be
unmatured. The rights of each Lender under this Section are in addition to other
rights and remedies (including other rights of setoff) which such Lender may
have.

         SECTION 8.07. Applicable Law. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS.

         SECTION 8.08. Waivers; Amendment.

         (a) No failure or delay of Borrower, the Administrative Agent, the
Issuing Bank or any Lender in exercising any power or right hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such right or power, or any abandonment or discontinuance of steps to enforce
such a right or power, preclude any other or further exercise thereof or the
exercise of any other right or power. The rights and remedies of the
Administrative Agent, the Issuing Bank and the Lenders hereunder are cumulative
and are not exclusive of any rights or remedies which they would otherwise have.
No waiver of any provision of this Agreement or consent to any departure
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) below, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given. No notice or demand
on the Borrower or any Subsidiary in any case shall entitle such party to any
other or further notice or demand in similar or other circumstances.

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan, or waive or excuse any such payment or any part
thereof, or decrease the rate of interest on any Loan, without the prior written
consent of each Lender directly affected thereby, or (ii) increase a Lender's
Commitment without the consent of such Lender, or (iii) decrease the Commitment
Fee Percentage or change the date on which the Commitment Fees are due and
payable without the prior written consent of each Lender directly affected
thereby, or (iv) amend or modify the provisions of Section 2.13 or Section
8.04(h), the provisions of this Section or the definition of the "Required
Lenders", without the prior written consent of each Lender; provided further,
however, that no such agreement shall amend, modify or otherwise affect the
rights or duties of (a) the Administrative Agent hereunder without the prior
written consent of the Administrative Agent, (b) the Issuing Bank hereunder
without the prior written consent of the Issuing Bank or (c) the Swingline
Lender hereunder without the prior written consent of the Swingline Lender.
Notwithstanding the foregoing, the Issuing Bank may be replaced in accordance
with Section 2.20(h) without the consent of the Required Lenders. Each Lender
shall be bound by any waiver, amendment or modification authorized by this
Section and any consent by any Lender pursuant to this Section shall bind any
assignee of its rights and interests hereunder.

         SECTION 8.09. Entire Agreement. THIS AGREEMENT (INCLUDING THE SCHEDULES
AND EXHIBITS HERETO), THE FEE LETTER AND THE OTHER DOCUMENTATION EXECUTED
PURSUANT HERETO (INCLUDING, BUT NOT LIMITED TO ANY LETTER OF CREDIT ISSUED
HEREUNDER) CONSTITUTE A "LOAN AGREEMENT" AS DEFINED IN SECTION 26.03(A) OF THE
TEXAS BUSINESS AND COMMERCE CODE, AND REPRESENT THE ENTIRE CONTRACT AMONG


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 57


<PAGE>   62
THE PARTIES RELATIVE TO THE SUBJECT MATTER HEREOF AND THEREOF. ANY PREVIOUS
AGREEMENT AMONG THE PARTIES WITH RESPECT TO THE SUBJECT MATTER HEREOF IS
SUPERSEDED BY THIS AGREEMENT, THE FEE LETTER AND THE OTHER DOCUMENTATION
EXECUTED PURSUANT HERETO (INCLUDING, BUT NOT LIMITED TO ANY LETTER OF CREDIT
ISSUED HEREUNDER). THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
NOTHING IN THIS AGREEMENT, EXPRESSED OR IMPLIED, IS INTENDED TO CONFER UPON ANY
PARTY OTHER THAN THE PARTIES HERETO ANY RIGHTS, REMEDIES, OBLIGATIONS OR
LIABILITIES UNDER OR BY REASON OF THIS AGREEMENT.

         SECTION 8.10. Severability. In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby. The parties shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

         SECTION 8.11. Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall constitute an original but all of which
when taken together shall constitute but one contract, and shall become
effective as provided in Section 8.03.

         SECTION 8.12. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

         SECTION 8.13. Interest Rate Limitation.

         (a) Notwithstanding anything herein to the contrary, if at any time the
applicable interest rate, together with all fees and charges which are treated
as interest under applicable law (collectively the "Charges"), as provided for
herein or in any other document executed in connection herewith, or otherwise
contracted for, charged, received, taken or reserved by any Lender, shall exceed
the maximum lawful rate (the "Maximum Rate") which may be contracted for,
charged, taken, received or reserved by such Lender in accordance with
applicable law, the rate of interest payable on the Loans or Swingline Loans of
such Lender, together with all Charges payable to such Lender, shall be limited
to the Maximum Rate.

         (b) If the amount of interest, together with all Charges, payable for
the account of any Lender in respect of any interest computation period is
reduced pursuant to paragraph (a) of this Section and the amount of interest,
together with all Charges, payable for such Lender's account in respect of any
subsequent interest computation period, computed pursuant to Section 2.06, would
be less than the Maximum Rate, then the amount of interest, together with all
Charges, payable for such Lender's account in respect of such subsequent
interest computation period shall, to the extent permitted by applicable law, be
automatically increased to such Maximum Rate; provided that at no time shall the
aggregate amount by which interest paid for the account of any Lender has been
increased pursuant to this paragraph (b) exceed the aggregate amount by which
interest, together with all Charges, paid for its account has theretofore been
reduced pursuant to paragraph (a) of this Section.

         (c) No provision of this Agreement shall require the payment or the
collection of interest in excess of the maximum amount permitted by applicable
law. If any excess of interest in such respect is hereby provided for, or shall
be adjudicated to be so provided, in this Agreement or otherwise in connection
with this loan transaction, the provisions of this Section shall govern and
prevail and neither the Borrower


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 58


<PAGE>   63
nor the sureties, guarantors, successors, or assigns of the Borrower shall be
obligated to pay the excess amount of such interest or any other excess sum paid
for the use, forbearance, or detention of sums loaned pursuant hereto. In the
event any Lender ever receives, collects, or applies as interest any such sum,
such amount which would be in excess of the maximum amount permitted by
applicable law shall be applied as a payment and reduction of the principal of
the Borrowings; and, if the principal of the Borrowings has been paid in full,
any remaining excess shall forthwith be paid to the Borrower. In determining
whether or not the interest paid or payable exceeds the Maximum Rate, the
Borrower and each Lender shall, to the extent permitted by applicable law, (a)
characterize any non-principal payment as an expense, fee, or premium rather
than as interest, (b) exclude voluntary prepayments and the effects thereof, and
(c) amortize, prorate, allocate, and spread in equal or unequal parts the total
amount of interest throughout the entire contemplated term of the Borrowings so
that interest for the entire term does not exceed the Maximum Rate.

         SECTION 8.14. Confidentiality. For the purposes of this Section 8.14,
"Confidential Information" means information delivered to the Administrative
Agent, the Issuing Bank or a Lender by or on behalf of the Borrower or any
Subsidiary in connection with the transactions contemplated by or otherwise
pursuant to this Agreement that is proprietary in nature and that was clearly
marked or labeled or otherwise adequately identified when received by the
Administrative Agent, the Issuing Bank or a Lender as being confidential
information of the Borrower or such Subsidiary, provided that such term does not
include information that (a) was publicly known or otherwise known to the
Administrative Agent, the Issuing Bank or a Lender prior to the time of such
disclosure, (b) subsequently becomes publicly known through no act or omission
by the Administrative Agent, the Issuing Bank or a Lender or any Person acting
on their behalf, (c) otherwise becomes known to the Administrative Agent, the
Issuing Bank or a Lender other than through disclosure by the Borrower or any
Subsidiary or (d) constitutes financial statements delivered to you under
Section 5.20 that are otherwise publicly available. The Administrative Agent,
the Issuing Bank and each Lender agree that they will maintain the
confidentiality of such Confidential Information in accordance with procedures
adopted by them in good faith to protect confidential information of third
parties delivered to them, provided that Administrative Agent, the Issuing Bank
or a Lender may deliver or disclose Confidential Information to (i) its
directors, officers, employees, agents, attorneys and affiliates (to the extent
such disclosure reasonably relates to the administration of this Agreement),
(ii) its financial advisors and other professional advisors who agree to hold
confidential the Confidential Information substantially in accordance with the
terms of this Section 8.14, (iii) any other Lender, (iv) any Transferee (if such
Person has agreed in writing prior to its receipt of such Confidential
Information to be bound by the provisions of this Section 8.14), (v) any Person
from which it offers to purchase any Security of the Borrower or a Subsidiary
(if such Person has agreed in writing prior to its receipt of such Confidential
Information to be bound by the provisions of this Section 8.14), (vi) any
federal or state regulatory authority having jurisdiction over it, (vii) any
nationally recognized rating agency that requires access to information about
its investment portfolio, or (viii) any other Person to which such delivery or
disclosure may be necessary or appropriate (w) to effect compliance with any
law, rule, regulation or order applicable to it, (x) in response to any subpoena
or other legal process, (y) in connection with any litigation to which it is a
party or (z) if an Event of Default has occurred and is continuing, to the
extent the Administrative Agent, the Issuing Bank or a Lender may reasonably
determine such delivery and disclosure to be necessary or appropriate in the
enforcement or for the protection of the rights and remedies under this
Agreement.

         SECTION 8.15. Non-Application of Chapter 346 of the Texas Finance Code.
The provisions of Chapter 346 of the Texas Finance Code are specifically
declared by the parties hereto not to be applicable to this Agreement or to the
transactions contemplated hereby.

         SECTION 8.16. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A


364 DAY REVOLVING CREDIT FACILITY AGREEMENT-Page 59


<PAGE>   64
TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.

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

OVERVIEW

Lennox participates in four reportable business segments of the heating,
ventilation, air conditioning, and refrigeration ("HVACR") industry. The first
segment is the North American residential market, in which Lennox manufactures
and markets a full line of heating, air conditioning and hearth products for the
residential replacement and new construction markets in the United States and
Canada. The North American residential segment also includes installation,
maintenance and repair services performed by Lennox-owned dealers. The second
segment is the global commercial air conditioning market, in which Lennox
manufactures and sells rooftop products and applied systems for commercial
applications. The third segment is the global commercial refrigeration market,
which consists of unit coolers, condensing units and other commercial
refrigeration products. The fourth segment is the heat transfer market, in which
Lennox designs, manufactures and sells evaporator and condenser coils, copper
tubing and related manufacturing equipment to original equipment manufacturers
and other specialty purchasers on a global basis.

         Lennox sells its products to numerous types of customers, including
distributors, installing dealers, homeowners, national accounts and original
equipment manufacturers. The demand for Lennox's products is influenced by
national and regional economic and demographic factors, such as interest rates,
the availability of financing, regional population and employment trends and
general economic conditions, especially consumer confidence. In addition to
economic cycles, demand for Lennox's products is seasonal and dependent on the
weather. Hotter than normal summers generate strong demand for replacement air
conditioning and refrigeration products and colder than normal winters have the
same effect on heating products. Conversely, cooler than normal summers and
warmer than normal winters depress sales of HVACR products.

         The principal components of cost of goods sold are labor, raw
materials, component costs, factory overhead and estimated costs of warranty
expense. The principal raw materials used in Lennox's manufacturing processes
are copper, aluminum and steel. In instances where Lennox is unable to pass on
to its customers increases in the costs of copper and aluminum, Lennox enters
into forward contracts for the purchase of those materials. Lennox attempts to
minimize the risk of price fluctuations in key components by entering into
contracts, typically at the beginning of the year, which generally provide for
fixed prices for its needs throughout the year. These hedging strategies enable
Lennox to establish product prices for the entire model year while minimizing
the impact of price increases of components and raw materials on its margins.
Warranty expense is estimated based on historical trends and other factors.

         In September 1997, Lennox increased its ownership in Ets. Brancher from
50% to 70%. As a result, Lennox assumed control of the venture and began
including the financial position and operating results of the venture in its
consolidated financial statements for the fourth quarter of 1997. Previously,
Lennox used the equity method of accounting for its investment in this entity.
In the fourth quarter of 1998, Lennox restructured its ownership of its various
European entities to allow for more efficient transfer of funds and to provide
for tax optimization.

         Lennox acquired Superior Fireplace Company, Marco Mfg., Inc. and Pyro
Industries, Inc. in the third quarter of 1998, and Security Chimneys
International, Ltd. in the first quarter of 1999 for an aggregate purchase price
of approximately $120 million. These acquisitions give Lennox one of the
broadest lines of hearth products in the industry.

                                                       LENNOX INTERNATIONAL INC.


         Lennox acquired James N. Kirby Pty. Ltd., an Australian company that
participates in the commercial refrigeration and heat transfer markets in
Australia, in June 1999 for approximately $65 million in cash, common stock and
seller financing. In addition, Lennox assumed approximately $20.5 million of
Kirby's debt.

         Lennox, through its Excel Comfort Systems subsidiary, purchased the
HVAC related assets of The Ducane Company, Inc. in October 1999 for
approximately $53 million in cash. This purchase will add to the brands offered
in the North American Residential segment.

         In September 1998, Lennox initiated a program to acquire high quality
heating and air conditioning dealers in metropolitan areas in the United States
and Canada to market "Lennox" and other brands of heating and air conditioning
products. This strategy will enable Lennox to extend its distribution directly
to the consumer and permit it to participate in the revenues and margins
available at the retail level while strengthening and protecting its brand
equity. Lennox believes that the retail sales and service market represents a
significant growth opportunity because this market is large and highly
fragmented. The retail sales and service market in the United States is
comprised of over 30,000 dealers. In addition, Lennox believes that the heating
and air conditioning service business is somewhat less seasonal than the
business of manufacturing and selling heating and air conditioning products. As
of December 31, 1999, Lennox had acquired 60 dealers in Canada and 33 dealers in
the United States for an aggregate purchase price of approximately $241 million
and had signed letters of intent to acquire 5 additional Canadian dealers and 18
United States dealers for an aggregate purchase price of approximately $59
million. As Lennox acquires more heating and air conditioning dealers, Lennox
expects that it will incur additional costs to expand its infrastructure to
effectively manage these businesses.

         On January 21, 2000, Lennox completed the acquisition of Service
Experts, Inc., an HVAC company comprised of HVAC retail businesses across the
United States, for approximately 12.2 million shares of Lennox common stock and
the assumption of $160 million of debt. The success of the Service Experts
acquisition, along with Lennox's other acquisitions, will depend on Lennox's
ability to integrate these businesses into its business without substantial
costs, delays or other operational or financial difficulties. The acquisition
added an additional 120 dealers to the U.S. retail network.

         Lennox's fiscal year ends on December 31 of each year, and its fiscal
quarters are each comprised of 13 weeks. For convenience, throughout this
Management's Discussion and Analysis of Financial Condition and Results of
Operations, the 13 week periods comprising each fiscal quarter are denoted by
the last day of the calendar quarter.

RESULTS OF OPERATIONS

The following table sets forth, as a percentage of net sales, Lennox's statement

YEAR ENDED DECEMBER 31, 1999
COMPARED TO YEAR ENDED DECEMBER 31, 1998

NET SALES. Net sales increased $539.9 million, or 29.6%, to $2,361.7 million for
the year ended December 31, 1999 from $1,821.8 million for the year ended
December 31, 1998.

         Net sales related to the North American residential segment were
$1,361.6 million for the year ended December 31, 1999, an increase of $347.9
million, or 34.3%, from $1,013.7 million for the year ended December 31, 1998.
Of the $347.9 million increase, $319.0 million was due to sales from the hearth
products acquisitions, acquired dealers, acquired heating and air conditioning
distributors, and the acquisition of Ducane's HVAC product lines. Sales to
dealers in the United States and Canada that Lennox has acquired are no longer
reflected as sales in Lennox's existing business and are instead reflected as
sales due to acquisitions. If sales to these acquired dealers were included in
sales of Lennox's existing business, sales of Lennox's existing business would
have increased by 5.9%. Excluding the sales to acquired dealers, there was an
increase of $28.9 million in North American residential net sales, primarily due
to a 2.9% increase in sales of Lennox's existing business, almost all of which
resulted from increased sales volumes, principally caused by two factors. First,
the hot summer in 1998 depleted the inventory levels at Lennox's customers and
they increased their purchases in the first quarter of 1999 to refill their
inventories. Second, Lennox's volume increased as a result of sales to new
dealers, which were added as a result of programs to expand Lennox's dealer
base.

         Commercial air conditioning net sales increased $60.7 million, or
15.5%, to $452.8 million for the year ended December 31, 1999 compared to the
year ended December 31, 1998. Of this increase, $29.8 million was due to
increased sales volumes in North America primarily due to the effectiveness of
commercial sales districts, and $30.9 million was due to increased international
sales, $6.5 million of which was due to acquisitions. Net sales related to the
commercial refrigeration segment were $327.3 million for the year ended December
31, 1999, an increase of $90.0 million or 37.9%, from $237.3 million for the
year ended December 31, 1998. Of this increase, $86.8 million was due to the
international acquisitions of Heatcraft do Brasil, the Lovelock Luke Pty.
Limited business and James N. Kirby Pty. Ltd. North American commercial
refrigeration sales increased $8.0 million primarily due to strong sales to
Lennox's supermarket customers and increased activity with Lennox's large
distributors. Heat transfer revenues increased $41.3 million, or 23.1%, to
$220.0 million for the year ended December 31, 1999 compared to the year ended
December 31, 1998. Of this increase, $7.3 million was due to increased sales
volumes in Lennox's existing North

American business and $37.7 million was due to the acquisitions of James N.
Kirby Pty. Ltd. and Livernois Engineering Holding Company.

GROSS PROFIT. Gross profit was $744.3 million for the year ended December 31,
1999 compared to $576.2 million for the year ended December 31, 1998, an
increase of $168.1 million. Gross profit margin was 31.5% for the year ended
December 31, 1999 and 31.6% for the year ended December 31, 1998. The increase
of $168.1 million in gross profit was primarily attributable to increased sales
in 1999 as compared to 1998. The gross profit margins of Lennox's traditional
businesses increased 0.7% for the twelve months of 1999 compared to the twelve
months of 1998.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses were $588.4 million for the year ended December 31,
1999, an increase of $118.8 million, or 25.3%, from $469.6 million for the year
ended December 31, 1998. Selling, general and administrative expenses
represented 24.9% and 25.7% of total revenues for the twelve months of 1999 and
1998, respectively. Of the $118.8 million increase, $99.5 million, or 83.8%, was
related to increased infrastructure associated with acquisitions. The majority
of the remaining $19.3 million increase was due to increases in selling, general
and administrative expenses for the North American residential segment which was
primarily comprised of increases in costs due to additions of personnel,
increased information technology costs and increased sales and marketing
expenses.

INTEREST EXPENSE, NET. Interest expense, net for the year ended December 31,
1999 increased to $33.1 million from $16.2 million for the year ended December
31, 1998. The increase in interest expense is attributable to the increased use
of credit lines and short-term borrowings to fund acquisitions, to make payments
related to the Pulse inspection program and for increased working capital
relating to increased sales.

OTHER. Other expense (income) was $(0.3) million for the year ended December 31,
1999 and $1.6 million for the year ended December 31, 1998. Other expense
(income) is primarily comprised of currency exchange gains or losses. The
majority of the reduction in other expense was due to the strengthening of the
Canadian dollar.

MINORITY INTEREST. Minority interest in subsidiaries' net losses of $(0.1)
million for the year ended December 31, 1999 and $(0.9) million for the year
ended December 31, 1998 represents the minority interest in Ets. Brancher,
Heatcraft do Brasil, and Kirby joint ventures.

PROVISION FOR INCOME TAXES. The provision for income taxes was $50.1 million for
the year ended December 31, 1999 and $37.2 million for the year ended December
31, 1998. The effective tax rate of 40.6% and 41.4% for the years ended December
31, 1999 and 1998, respectively, differs from the statutory federal rate of
35.0% principally due to state and local taxes, non-deductible goodwill
expenses, and foreign operating losses for which no tax benefits have been
recognized.

YEAR ENDED DECEMBER 31, 1998
COMPARED TO YEAR ENDED DECEMBER 31, 1997

NET SALES. Net sales increased $377.4 million, or 26.1%, to $1,821.8 million for
the year ended December 31, 1998 from $1,444.4 million for the year ended
December 31, 1997. If the effect of the consolidation of Ets. Brancher is
excluded, net sales would have increased by $226.7 million, or 16.1%, to
$1,630.9 million for 1998 as compared to 1997.




                                                                              23

         Net sales related to the North American residential segment were
$1,013.7 million during 1998, an increase of 17.2% from $865.1 million for 1997.
This increase was primarily due to increased unit sales of "Lennox" and
"Armstrong Air" brands of heating and air conditioning equipment and the
inclusion beginning in the third quarter of 1998 of $68.6 million of sales of
the hearth products companies. Hot weather in the spring of 1998 and an expanded
dealer and distributor base led to greater sales of the "Lennox" and "Armstrong
Air" brands. Commercial air conditioning revenues increased $113.3 million, or
40.6%, to $392.1 million for 1998 compared to 1997. If the effect of the
consolidation of Ets. Brancher is excluded, commercial air conditioning revenues
would have increased $46.5 million, or 17.9%, to $306.1 million for 1998 as
compared to 1997. This increase was primarily due to increased volumes of
rooftop air conditioner sales in the United States and Canada. Net sales related
to the commercial refrigeration segment were $237.3 million during 1998, an
increase of 53.8% from $154.3 million for 1997. If the effect of the
consolidation of Ets. Brancher is excluded, net sales related to the commercial
refrigeration products segment would have increased $20.2 million, or 14.8%, to
$156.8 million for 1998 as compared to 1997. This increase is primarily caused
by sales volume increases due to hot weather in North America in 1998 and the
acquisition of Heatcraft do Brasil in September 1998. Heat transfer revenues
increased $32.5 million, or 22.3%, to $178.7 million for 1998 compared to 1997.
If the effect of the consolidation of Ets. Brancher is excluded, heat transfer
revenues would have increased $11.4 million, or 8.0%, to $154.3 million for 1998
as compared to 1997. This increase is primarily caused by sales volume increases
due to hot weather in North America in 1998.

         Domestic sales increased $197.4 million, or 15.5%, to $1,472.3 million
for 1998 from $1,274.9 million for 1997. Of this increase, $68.6 million is due
to the inclusion of the hearth products companies and the balance was caused
primarily by increased unit sales of "Lennox" and "Armstrong Air" brands due to
the hot weather in 1998 and an expanded dealer and distributor base for these
brands. International sales increased $180.0 million, or 106.2%, to $349.5
million for 1998 from $169.5 million for 1997. Of this increase, $150.7 million
is due to the consolidation of Ets. Brancher and the remainder is primarily due
to the acquisition of Heatcraft do Brasil and the Lovelock Luke business.

GROSS PROFIT. Gross profit was $576.2 million for the year ended December 31,
1998 as compared to $438.5 million for the year ended December 31, 1997, an
increase of $137.7 million. Gross profit margin increased to 31.6% in 1998 from
30.4% for 1997. The increase of $137.7 million in gross profit was primarily
attributable to increased sales in 1998 as compared to 1997 and the effect of
the consolidation of Ets. Brancher for the full year. Ets. Brancher contributed
$47.7 million and $11.2 million to gross profit in 1998 and 1997, respectively,
and its gross profit margin was 25.0% and 27.9% in 1998 and 1997, respectively.
If the effect of the consolidation of Ets. Brancher is excluded, gross profit
margin would have been 32.4% and 30.4% for 1998 and 1997, respectively. The
improved gross profit margin for 1998 is due to lower material costs, improved
manufacturing processes and increased overhead absorption associated with the
higher volume of sales in North America.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses were $469.6 million for 1998, an increase of $135.8
million, or 40.7%, from $333.8 million for 1997. Selling, general and
administrative

expenses represented 25.7% and 23.1% of total net revenues for 1998 and 1997,
respectively. If the effect of the consolidation of Ets. Brancher is excluded,
selling, general and administrative expenses would have been $422.4 million for
1998, an increase of $100.9 million, or 31.4%, from $321.5 million for 1997,
representing 25.9% and 22.9% of total net sales for 1998 and 1997, respectively.
Approximately $16.7 million of the increase in selling, general and
administrative expenses is composed of three non-recurring items: $7.1 million
associated with the settlement of a lawsuit; approximately $5.0 million of
incremental expense associated with the implementation of the SAP enterprise
business software system; and $4.6 million associated with increased expenses of
a terminated performance share plan. If the effect of these non-recurring items
and the consolidation of Ets. Brancher is excluded, selling, general and
administrative expenses would have been $405.7 million for 1998, an increase of
$84.2 million, or 26.2%, from $321.5 million for 1997, representing 24.9% and
22.9% of total net sales for 1998 and 1997, respectively. The remaining increase
in selling, general and administrative expenses is primarily due to increased
variable costs associated with sales growth in North America and costs
associated with creating infrastructure to manage international businesses, such
as the establishment of a sales office in Singapore and the business development
functions for Lennox's global operation.

PRODUCT INSPECTION CHARGE. In the fourth quarter of 1997, Lennox recorded a
non-recurring pre-tax charge of $140.0 million to provide for management's best
estimate of the projected expenses of the product inspection program related to
its Pulse furnace. As part of Lennox's normal warranty process, Lennox
continuously monitors the replacement rate for, among other components, heat
exchangers in its products. During 1997, it was determined that, under certain
circumstances, certain joint connections on Pulse furnace heat exchangers
manufactured between 1982 and 1988 could fail and potentially create a safety
hazard in the home. Once this was determined, Lennox publicly announced the
Pulse inspection program in 1997. Under the program, Lennox offered the owners
of all Pulse furnaces installed between 1982 and 1990 a subsidized inspection
and a free carbon monoxide detector. The inspection included a severe pressure
test to determine the serviceability of the heat exchanger. If the heat
exchanger did not pass the test, Lennox either replaced the heat exchanger or
offered a new furnace and subsidized the labor costs for installation. The cost
required for the program depended on the number of units Lennox found, the
number of units that failed the pressure test, whether consumers selected to
replace the heat exchanger or receive a new furnace and the cost of the
replacement products. Based on the results of Lennox's historical experience,
input from Lennox's dealers and consultation with the Consumer Products Safety
Commission, Lennox estimated that it could ultimately locate approximately 67%
of the Pulse furnaces that were manufactured between 1982 and 1988. In terms of
estimated failure rates, Lennox utilized the data gathered from "field
experience" tests, which indicated a failure rate of approximately 30%. In terms
of consumer selection, Lennox estimated that half would elect the new heat
exchanger and half would elect the new furnace. Finally, Lennox utilized its
standard costs of heat exchangers and new furnaces, the cost of the dealer
inspection allowance and the cost of the dealer replacement allowance in
calculating the liability. Lennox believes that it had adequate information to
develop reasonable assumptions in estimating the cost of the Pulse inspection
program. The program ended on June 30, 1999 and future expenses associated with
the program are not expected to be significant.




                                                                              25

INCOME (LOSS) FROM OPERATIONS. Income (loss) from operations was $106.6 million
for 1998 compared to $(35.2) million for 1997. Excluding the Ets. Brancher
consolidation, the special charge for the Pulse inspection program and the three
non-recurring selling, general and administrative expense items mentioned above,
income from operations would have been $122.6 million for 1998, or 7.5% of net
sales, as compared to $106.1 million for 1997, or 7.6% of net sales.

INTEREST EXPENSE, NET. Interest expense, net for 1998 increased to $16.2 million
from $8.5 million for 1997. Of the $7.7 million increase in interest expense,
$3.6 million was due to the incurrence of $75 million in additional long-term
borrowings in April 1998, $1.6 million was due to the consolidation of Ets.
Brancher for the full year and the remainder was due to less interest income in
1998.

OTHER. Other expense was $1.6 million for 1998 and $2.0 million for 1997. Other
expense is primarily comprised of currency exchange gains or losses.

MINORITY INTEREST. Minority interest in subsidiaries' net loss of $(0.7) million
in 1997 and $(0.9) million in 1998 represents the minority interest in Ets.
Brancher and, for 1998, Heatcraft do Brasil.

PROVISION (BENEFIT) FOR INCOME TAXES. The effective tax rates for the 1998
provision and the 1997 benefit were 41.4% and 25.5%, respectively. The effective
tax rates differ from the federal statutory rate of 35% primarily due to state
income taxes and valuation reserves provided for foreign operating losses.

NET INCOME (LOSS). Net income (loss) was $52.5 million and $(33.6) million for
the year ended December 31, 1998 and 1997, respectively. If the effects of the
consolidation of Ets. Brancher and the non-recurring charge relating to the
Pulse inspection program are excluded, net income would have been $52.9 million
and $55.2 million for 1998 and 1997, representing 3.2% and 3.9% of net sales for
1998 and 1997, respectively.

LIQUIDITY AND CAPITAL RESOURCES

As a result of Lennox's domestic and international growth in 1999, capital
requirements have related principally to acquisitions, the expansion of its
production capacity and increased working capital needs that have accompanied
sales growth.

         Net cash provided by operating activities totaled $70.6 million, $5.0
million and $58.5 million for 1999, 1998 and 1997, respectively. The increase in
cash from operating activities in 1999 is primarily due to increased cash
income, reduced inventory levels and lower income tax payments as the cash
payouts of the Pulse inspection program reduced taxes then currently payable.
The reduction in cash from operating activities from 1997 to 1998 is primarily
due to the Pulse inspection program on which Lennox spent $86.1 million in 1998.
Net cash used in investing activities totaled $407.4 million, $212.4 million and
$44.6 million for 1999, 1998 and 1997, respectively. Spending for capital
improvements increased $24.3 million in 1999 over 1998, and $17.8 million in
1998 over 1997. Investments in acquired businesses accounted for an increase in
investment spending of $173.7 million in 1999 over 1998 and $149.5 million in
1998 over 1997. Net cash provided by (used in) financing activities was $338.7
million, $89.5 million and

($17.3) million for 1999, 1998 and 1997, respectively. Cash for financing
activities was provided by increasing debt $223.5 million in 1999 and $99.2
million in 1998. The public offering of stock, along with the exercise of stock
options, generated $141.9 million of cash in 1999.

         Lennox's capital expenditures were $76.7 million, $52.4 million, and
$34.6 million for 1999, 1998 and 1997, respectively. Capital expenditures in
1999 related to production equipment (including tooling), training facilities,
leasehold improvements and information systems. These capital expenditures were
financed using cash flow from operations and available borrowings under Lennox's
revolving credit facility.

         Lennox will continue to acquire additional heating and air conditioning
dealers in the United States and Canada. Lennox plans to finance these
acquisitions with a combination of cash, stock and debt. As of December 31,
1999, Lennox had acquired 60 dealers in Canada and 33 in the United States for
an aggregate purchase price of approximately $241 million and had signed letters
of intent to acquire five additional Canadian dealers and 18 United States
dealers for an aggregate purchase price of approximately $59 million.

         On August 3, 1999, Lennox completed the initial public offering of its
common stock. Lennox sold 8,088,490 shares of its common stock, and certain
selling stockholders sold 411,510 shares, at an initial price to the public of
$18.75 per share. Net proceeds from the offering were $139.4 million, after
deducting estimated expenses and underwriting discounts and commissions.
Proceeds from the offering were used to repay a portion of the borrowings under
Lennox's former revolving credit facility and a term credit facility which
terminated upon completion of the offering.

         Lennox will purchase the remaining 30% interest in Ets. Brancher for
approximately $17 million in the first half of 2000. In June 1999, Lennox
acquired James N. Kirby Pty. Ltd. for approximately $65 million. In addition,
approximately $20.5 million of Kirby's debt was assumed. The purchase price
consisted of approximately $16 million in cash, $33 million in deferred payments
and 650,430 shares of Lennox common stock. The $33 million in deferred payments
will be made in installments of approximately $11 million per year over the next
three years. If Lennox common stock does not trade at a price greater than
$29.09 per share for five consecutive days from the period from June 2000 to
June 2001, then Lennox is obligated to pay the former owners of Kirby the
difference between the trading price for the last five days of this period and
$29.09 for 577,500 of the shares of Lennox common stock.

         At December 31, 1999, Lennox had long-term debt obligations outstanding
of $554.8 million. The majority of the long-term debt consists of five issues of
notes with an aggregate principal amount of $206.0 million, interest rates
ranging from 6.56% to 9.53% and maturities ranging from 2001 to 2008, and
amounts aggregating $258.0 million borrowed under a $300.0 million revolving
credit agreement. The notes and revolving credit agreement contain restrictive
covenants, including financial maintenance covenants and covenants that place
limitations on Lennox's ability to incur additional indebtedness, encumber its
assets, sell its assets or pay dividends. The ratio of total funded debt to
earnings before interest, taxes, depreciation and amortization ("EBITDA") cannot
exceed 3.0 based upon a rolling four quarter basis. The ratio of EBITDA less
capital expenditures to interest expense should be greater than 3.0 based on a
rolling four quarter basis. Lennox's ability to incur debt is limited to 60.0%
of its consolidated capitalization. As of December 31, 1999, Lennox's
consolidated indebtedness as a percent of consolidated capitalization was 43.7%
as defined in the note



                                                                              27

agreements. Generally, the aggregate sale of assets outside the ordinary course
of business cannot exceed 15% of Lennox's consolidated assets during any fiscal
year and all transfers after January 1, 1998 cannot exceed 30% of Lennox's
consolidated assets. In addition, in order to pay dividends or make a sale of
assets outside the ordinary course of business, Lennox must be able to incur
$1.00 of additional indebtedness. In addition, Lennox is required to maintain a
consolidated net worth equal to $261.0 million plus 15% of Lennox's consolidated
quarterly net income beginning April 1, 1998. At December 31, 1999, the required
consolidated net worth was $279.4 million and Lennox had a consolidated net
worth of $613.5 million as defined in the agreement. Upon a change of control,
Lennox must make an offer to repurchase the notes at a price equal to 100% of
the principal amount of the notes, plus accrued and unpaid interest. Lennox's
debt service requirement (including principal and interest payments) for its
currently outstanding long-term debt is $54 million for 2000. As of December 31,
1999, Lennox had approximate minimum commitments on all non-cancelable operating
leases of $30.2 million and $24.4 million in 2000 and 2001, respectively.

         Lennox has a multi-year $300 million revolving credit facility with a
syndicate of banks led by Chase Bank of Texas, National Association, as
administrative agent, Wachovia Bank, N.A., as syndication agent, and The Bank of
Nova Scotia, as documentation agent. The credit facility has restrictive
covenants and maintenance tests identical to those in the notes. Borrowings
under this credit facility bear interest, at Lennox's option, at a rate equal to
either (a) the greater of the administrative agent's prime rate or the federal
funds rate plus 0.5% or (b) the London Interbank Offered Rate plus a margin
equal to 0.5% to 1.125%, depending upon Lennox's ratio of total funded debt to
EBITDA. Lennox pays a commitment fee equal to 0.15% to 0.30% of the unused
commitment, depending upon the ratio of total funded debt to EBITDA. This credit
facility has a term of five years. Additionally, Lennox entered into a $300
million, 364 day, revolving credit facility in January 2000. This facility
contains similar terms and covenants as the multi-year revolving credit
facility.

         Lennox signed an agreement in October 1999 with The Prudential
Insurance Company of America which will allow it to borrow up to $100 million in
the form of senior notes from time to time within the first three years of the
agreement. The minimum amount of notes that can be drawn at any one time will be
$10 million and the maturity and interest rate will be selected from
alternatives provided by Prudential at the time the notes are issued, up to a
maximum maturity of 15 years. The agreement has customary covenants that are
substantially similar to those contained in Lennox's other outstanding series of
notes.

         Lennox announced a two-phase stock buy-back plan to repurchase,
depending on market conditions and other factors, up to 5 million shares of
Lennox common stock. A total of 1,172,200 shares had been purchased at an
average cost of $10.566 in the fourth quarter of 1999. Purchases under the share
repurchase program will be made on an open-market basis at prevailing market
prices in accordance with the applicable rules and regulations governing such
purchases. The timing of any repurchases will depend on market conditions, the
market price of Lennox common stock, and management's assessment of Lennox's
liquidity and cash flow needs. Lennox has also entered into a series of forward
purchase contracts, which it may use in connection with the stock repurchase
program. The terms of these contracts permit settlement on a net share basis and
provide that the stock repurchased will remain issued and outstanding until the
forward purchase contracts are settled. Lennox expects the settlement of any of
such contracts to begin in the third quarter of 2000.

         Lennox believes that cash flow from operations, as well as available
credit facilities, will be sufficient to fund its operations and the ongoing
business enterprise endeavors for the foreseeable future. Lennox may pursue
additional debt or equity financing in connection with acquisitions.

MARKET RISK

Lennox's results of operations can be affected by changes in exchange rates. Net
sales and expenses in currencies other than the United States dollar are
translated into United States dollars for financial reporting purposes based on
the average exchange rate for the period. During 1999, 1998 and 1997, net sales
from outside the United States represented 26.7%, 19.2%, and 11.7%,
respectively, of total net sales. Historically, foreign currency transaction
gains (losses) have not had a material effect on Lennox's operations.

         Lennox has entered into foreign currency exchange contracts to hedge
its investment in Europe. Lennox does not engage in currency speculation. These
contracts do not subject Lennox to risk from exchange rate movements because the
gains or losses on the contracts offset the losses or gains, respectively, on
the assets and liabilities of its European companies. As of December 31, 1999,
Lennox had entered into foreign currency exchange contracts with a nominal value
of 165.5 million French francs (approximately $25.4 million). These contracts
require Lennox to exchange Euros for United States dollars at maturity, which is
in May 2003, at rates agreed to at inception of the contracts. If the
counterparties to the exchange contracts do not fulfill their obligations to
deliver the contracted currencies, Lennox could be at risk for any currency
related fluctuations.

         From time to time Lennox enters into foreign currency exchange
contracts to hedge receivables and payables denominated in foreign currencies.
These contracts do not subject Lennox to risk from exchange rate movements
because the gains or losses on the contracts offset losses or gains,
respectively, on the receivables or payables being hedged. As of December 31,
1999, Lennox had obligations to deliver the equivalent of $26.3 million of
various foreign currencies at various dates over the next nine months, for which
the counterparties to the contracts will pay fixed contract amounts, and
obligations to take the equivalent of $2.2 million of various currencies at
various dates over the next two months.

         Lennox has contracts with various suppliers to purchase copper and
aluminum for use in its manufacturing processes. As of December 31, 1999, Lennox
had contracts to purchase 21.2 million pounds of copper over the next 12 months
at fixed prices that average $0.73 per pound ($15.5 million) and contracts to
purchase 6 million pounds of copper at a variable price equal to the COMEX
copper price ($0.85 per pound at December 31, 1999) over the next 12 months.
Lennox also had contracts to purchase 3.7 million pounds of aluminum at $0.69
per pound ($2.6 million) over the next 12 months. Additionally, Lennox had
contracts to purchase 9.3 million pounds of aluminum fin stock over the next 12
months at a fixed price of $1.04 per pound ($9.8 million). The fair value of the
copper and aluminum purchase commitments was an asset at December 31, 1999 of
$3.0 million and a liability of $2.6 million at December 31, 1998.

INFLATION

Historically, inflation has not had a material effect on Lennox's results of
operations.

YEAR 2000 COMPLIANCE

The Year 2000 issue concerns the ability of information technology and
non-information technology systems and processes to properly recognize and
process date-sensitive information before, during and after December 31, 1999.
Lennox has a variety of computer software program


                                                                              29

applications, computer hardware equipment and other equipment with embedded
electronic circuits, including applications used in its financial business
systems, manufacturing processes and administrative functions, which are
collectively referred to as the "systems." As of December 31, 1999, Lennox was
100% complete with the implementation of the Year 2000 compliance program for
all of its systems.

         Lennox's cost to become Year 2000 compliant was approximately $6.4
million, all of which was recorded as a reduction of net income. Such costs do
not include the costs of application and infrastructure changes that were made
for reasons other than the Year 2000 and that were not accelerated because of
the Year 2000. All Year 2000 costs were funded from operating cash flows and
were not incremental to existing information technology budgets. The Company
does not anticipate incurring any additional costs as a result of the Year 2000
issue.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." This statement establishes accounting and reporting
standards for derivative instruments, including certain derivatives embedded in
other contracts (collectively referred to as derivatives) and for hedging
activities. This statement, for Lennox, is effective with the first quarter of
2001. Lennox does not believe that the adoption of this pronouncement will have
a significant impact on its financial statements.

REPORT OF MANAGEMENT



The Company's management is responsible for the preparation and accuracy of the
financial statements. Management believes that the financial statements for the
three years ended December 31, 1999, have been prepared in conformity with
generally accepted accounting principles and set forth a fair presentation of
the financial condition and results of operations.

         In meeting its responsibility for the reliability of the financial
statements, management relies on a system of internal accounting controls.
Management believes that the accounting systems and related controls that it
maintains are sufficient to provide reasonable assurance that financial records
are reliable for preparing financial statements and maintaining accountability
for assets. These systems and controls are tested and evaluated regularly by the
Company's internal auditors.

         The Audit Committee of the Board of Directors, which is composed solely
of Directors who are independent of the Company, is responsible for monitoring
the Company's accounting and reporting practices. The Audit Committee meets
periodically with the Company's management, the internal auditors and the
independent public accountants and monitors the accounting affairs of the
Company. The independent accountants have free access to the Audit Committee and
the Board of Directors to discuss internal accounting control, auditing and
financial reporting matters.

         The independent public accountants are engaged to express an opinion on
the Company's consolidated financial statements. They have developed an overall
understanding of our accounting and financial controls and have conducted other
tests as they consider necessary to support their opinion on the financial
statements. The opinion of the independent public accountants is based on
procedures which they believe to be sufficient to provide reasonable assurance
that the financial statements contain no material errors.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders and Board of Directors of
Lennox International Inc.:

We have audited the accompanying consolidated balance sheets of Lennox
International Inc. (a Delaware corporation) and Subsidiaries as of December 31,
1999 and 1998, and the related consolidated statements of income, stockholders'
equity, and cash flows 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.

         We conducted our audits in accordance with generally accepted auditing
standards. 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 provide a reasonable basis for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Lennox International
Inc. 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 generally accepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



For the Years Ended December 31, 1999, 1998 and 1997

1. NATURE OF OPERATIONS:

Lennox International Inc. and subsidiaries (the "Company"), a Delaware
corporation, is a global designer, manufacturer, and marketer of a broad range
of products for the heating, ventilation, air conditioning, and refrigeration
("HVACR") markets. The Company participates in four reportable business segments
of the HVACR industry. The first is North American residential heating, air
conditioning and hearth products, in which the Company manufactures and markets
a full line of products for the residential replacement and new construction
markets in North America. The second reportable segment is the global commercial
air conditioning market, in which the Company manufactures and sells rooftop
products and applied systems for commercial applications. The third is the
global commercial refrigeration market, which consists of unit coolers,
condensing units and other commercial refrigeration products. The fourth
reportable segment is heat transfer products, in which the Company designs,
manufactures and sells evaporator and condenser coils, copper tubing, and
related equipment to original equipment manufacturers ("OEMs") and other
specialty purchasers on a global basis. See Note 4 for financial information
regarding the Company's reportable segments.

         The Company sells its products to numerous types of customers,
including distributors, installing dealers, national accounts and OEMs.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

PRINCIPLES OF CONSOLIDATION   The consolidated financial statements include the
accounts of Lennox International Inc. and its subsidiaries. All intercompany
transactions and balances have been eliminated. Investments in joint ventures
where the Company has a 50% or less ownership interest are being accounted for
using the equity method of accounting.

         As discussed in Note 7, the Company increased its ownership in Ets.
Brancher from 50% to 70% in September 1997. As a result, the Company assumed
control of the venture and began consolidating the financial position and
results of operations in the fourth quarter of 1997. Previously, the Company
used the equity method of accounting for its investment in this entity.

CASH EQUIVALENTS   The Company considers all highly liquid temporary investments
with original maturity dates of three months or less to be cash equivalents.
Cash equivalents consist of investment grade securities and are stated at cost
which approximates fair value. The Company earned interest income of $2.6
million, $4.5 million and $6.4 million for the years ended December 31, 1999,
1998 and 1997, respectively, which is included in interest expense, net on the
accompanying consolidated statements of income.

ACCOUNTS AND NOTES RECEIVABLE   Accounts and notes receivable have been shown
net of an allowance for doubtful accounts of $21.2 million and $18.5 million as
of December 31, 1999 and 1998, respectively. The Company has no significant
credit risk concentration among its diversified customer base.

INVENTORIES   Inventory costs include applicable material, labor, depreciation,
and plant overhead. Inventories of $183.7 million and $169.6 million in 1999 and
1998, respectively, are valued at the lower of cost or market using the last-in,
first-out (LIFO) cost method. The remaining portion of the inventory is valued
at the lower of cost or market with cost being determined either on the
first-in, first-out (FIFO) basis or average cost.

                                                       LENNOX INTERNATIONAL INC.


PROPERTY, PLANT AND EQUIPMENT   Property, plant and equipment is stated at
cost, net of accumulated depreciation. Expenditures for renewals and betterments
are capitalized, and expenditures for maintenance and repairs are charged to
expense as incurred. Gains and losses resulting from the dispositions of
property, plant and equipment are included in other operating expense.
Depreciation is computed using the straight-line method over the following
estimated useful lives:

- -------------------------------------------------
Buildings and improvements         10 to 39 years

Machinery and equipment             3 to 10 years
- -------------------------------------------------


GOODWILL AND OTHER INTANGIBLE ASSETS   Goodwill and other intangible assets have
been recorded based on their fair value at the date of acquisition and are being
amortized on a straight-line basis over periods generally ranging from thirty to
forty years. As of December 31, 1999 and 1998, accumulated amortization was
$41.5 million and $34.4 million, respectively.

         The Company periodically reviews long-lived assets and identifiable
intangibles for impairment as events or changes in circumstances indicate that
the carrying amount of such assets may not be recoverable. In order to assess
recoverability, the Company compares the estimated expected future cash flows
(undiscounted and without interest charges) identified with each long-lived
asset or related asset grouping to the carrying amount of such assets. For
purposes of such comparisons, portions of goodwill are attributed to related
long-lived assets and identifiable intangible assets based upon relative fair
values of such assets at acquisition. If the expected future cash flows do not
exceed the carrying value of the asset or assets being reviewed, an impairment
loss is recognized based on the excess of the carrying amount of the impaired
assets over their fair value. As a result of these periodic reviews, there have
been no adjustments to the carrying value of long-lived assets, identifiable
intangibles, or goodwill in 1999, 1998 and 1997.

PRODUCT WARRANTIES   A liability for estimated warranty expense is established
by a charge against operations at the time products are sold. The subsequent
costs incurred for warranty claims serve to reduce the product warranty
liability. The Company recorded warranty expense of $21.5 million, $15.6 million
and $17.7 million for the years ended December 31, 1999, 1998, and 1997,
respectively.

         The Company's estimate of future warranty costs is determined for each
product line. The number of units that are expected to be repaired or replaced
is determined by applying the estimated failure rate, which is generally based
on historical experience, to the number of units that have been sold and are
still under warranty. The estimated units to be repaired under warranty are
multiplied by the average cost (undiscounted) to repair or replace such products
to determine the Company's estimated future warranty cost. The Company's
estimated future warranty cost is subject to adjustment from time to time
depending on actual experience.

         Total liabilities for estimated warranty expense are $55.7 million and
$83.2 million as of December 31, 1999 and 1998, respectively, and are included
in the following captions on the accompanying consolidated balance sheets (in
thousands):

         The liability for estimated warranty expense as of December 31, 1998,
included $27.3 million in remaining estimated liabilities associated with a
product inspection program initiated in 1997 (see Note 3).


                                                                              37

INCOME TAXES   Income taxes are accounted for under the asset and liability
method. Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

REVENUE RECOGNITION   Sales are recorded when products are shipped or when
services are rendered.

RESEARCH AND DEVELOPMENT EXPENSES   Research and development costs are expensed
as incurred. The Company expended approximately $39.1 million, $33.3 million,
and $25.4 million for the years ended December 31, 1999, 1998, and 1997,
respectively, for research and product development activities. Research and
development costs are included in selling, general and administrative expense on
the accompanying consolidated statements of income.

ADVERTISING   Production costs of commercials and programming are charged to
operations in the period first aired. The costs of other advertising, promotion
and marketing programs are charged to operations in the period incurred.
Advertising expense was $62.3 million, $50.2 million, and $37.9 million for the
years ended December 31, 1999, 1998, and 1997, respectively.

TRANSLATION OF FOREIGN CURRENCIES   All assets and liabilities of foreign
subsidiaries and joint ventures are translated into United States dollars using
rates of exchange in effect at the balance sheet date. Revenues and expenses are
translated at average exchange rates during the respective years. The unrealized
translation gains and losses are accumulated in a separate component of
stockholders' equity. Transaction gains (losses) included in the accompanying
statements of income were $287,000, $(1,602,000) and $(1,955,000) for the years
ended December 31, 1999, 1998, and 1997, respectively.

FOREIGN CURRENCY CONTRACTS   The Company has entered into foreign currency
exchange contracts to hedge its investment in Ets. Brancher S.A. (see Note 7)
and not to engage in currency speculation. These contracts do not subject the
Company to risk from exchange rate movements because the gains or losses on the
contracts offset the losses or gains, respectively, on the assets and
liabilities of the subsidiary. The Company has entered into contracts to sell
165.5 million French francs on May 7, 2003 for $31.7 million. The fair value of
these contracts was approximately $6.3 million and $2.1 million as of December
31, 1999 and 1998, respectively.

         These contracts require the Company to exchange Euros for United States
dollars at maturity (May 2003), at rates agreed to at inception of the
contracts. If the counterparty to the exchange contracts does not fulfill their
obligations to deliver the contracted currencies, the Company could be at risk
for any currency-related fluctuations. The gains and losses associated with
these contracts, net of tax, are recorded as a component of accumulated other
comprehensive loss on the accompanying 1999, 1998 and 1997 consolidated
statements of stockholders' equity.

         The Company from time to time enters into foreign exchange contracts to
hedge receivables or payables denominated in foreign currencies, and not to
engage in currency speculation. These contracts do not subject the Company to
risk from exchange rate movements because the gains or losses on the contracts
offset losses or gains,

respectively, on the items being hedged. As of December 31, 1999, the Company
had obligations to deliver $26.3 million of various currencies over the next
nine months, and to take possession of $2.2 million of various currencies over
the next two months. The fair value of the various contracts represented a net
asset of $1.3 million as of December 31, 1999 and was insignificant at December
31, 1998.

PURCHASE COMMITMENTS   The Company has contracts with various suppliers to
purchase copper and aluminum for use in its manufacturing processes. As of
December 31, 1999, the Company had contracts to purchase 21.2 million pounds of
copper over the next 12 months at fixed prices that average $0.73 per pound
($15.5 million) and contracts to purchase 6 million pounds of copper at a
variable price equal to the COMEX copper price ($0.85 per pound at December 31,
1999) over the next 12 months. The Company also had contracts to purchase 3.7
million pounds of aluminum at $0.69 per pound ($2.6 million) over the next 12
months. Additionally, the Company had contracts to purchase 9.3 million pounds
of aluminum fin stock over the next 12 months at a fixed price of $1.04 per
pound ($9.8 million). The fair value of the copper and aluminum purchase
commitments was an asset of $3.0 million at December 31, 1999, and was a
liability at December 31, 1998 of $2.6 million.

USE OF ESTIMATES   The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

RECLASSIFICATIONS   Certain amounts have been reclassified from the prior year
presentation to conform to the current year presentation.

3. PRODUCT INSPECTION CHARGE:

During 1997, the Company recorded a pre-tax charge of $140.0 million to provide
for projected expenses of the product inspection program related to its Pulse
furnace. The Company offered the owners of Pulse furnaces installed between 1982
and 1990 a subsidized inspection and a free carbon monoxide detector. The
inspection included a severe pressure test to determine the serviceability of
the heat exchanger. If the heat exchanger did not pass the test, the Company
offered to either replace the heat exchanger or supply a new furnace and
subsidize the labor costs for installation. The cost required for the program
depended on the number of furnaces located, the percentage of those located that
did not pass the pressure test, and the replacement option chosen by the
homeowner.

         As of December 31, 1998, the Company had incurred approximately $112.7
million in costs related to the product inspection program. Consequently, there
is a current liability of $27.3 million recorded on the accompanying
consolidated balance sheet as of December 31, 1998, to accrue for the estimated
remaining costs of the program. The product inspection program ended in June
1999.

4. REPORTABLE BUSINESS SEGMENTS:

In accordance with Statement of Financial Accounting Standards ("SFAS") No. 131,
the Company discloses business segment data for its reportable business
segments, which have been determined using the "management approach." The
management approach is based on the way segments are organized within the
Company for making operating decisions and assessing performance. The Company's
business operations are organized within the following four reportable business
segments as follows


                                                                              39

7. INVESTMENTS IN JOINT VENTURES AND SUBSIDIARIES:

ETS. BRANCHER   In May 1996, the Company's subsidiary, Lennox Global Ltd.,
acquired a 50% interest in HCF-Lennox, a manufacturer of air conditioning and
refrigeration equipment. In addition to acquiring an interest in HCF-Lennox, the
Company increased its ownership of an existing joint venture, Friga-Bohn, from
20% to 50%. Effective September 30, 1997, Lennox Global Ltd. acquired an
additional 20% interest in HCF-Lennox and Friga-Bohn. In conjunction with the
purchase, the stock of HCF-Lennox and Friga-Bohn was combined into an existing
holding company, Ets. Brancher S.A. Ets. Brancher also owns certain land and
buildings that were leased to HCF-Lennox and Friga-Bohn. As a result of the
acquisition (the "1997 Ets. Brancher Acquisition"), Lennox Global Ltd. owns 70%
of HCF-Lennox and Friga-Bohn as well as a 70% interest in the land and buildings
through its ownership of 70% of the stock of Ets. Brancher S.A. The aggregate
purchase price for the 1997 Ets. Brancher Acquisition was $18.4 million, of
which $10 million was in cash and $8.4 million was in Company stock (631,389
shares). The acquisition was accounted for in accordance with the purchase
method of accounting. Accordingly, the purchase price has been allocated to the
assets and liabilities based upon their estimated fair values at the date of
acquisition. As a result, the Company recorded additional goodwill of
approximately $6.4 million, which is being amortized on a straight-line basis
over a 30-year period.

         The Company has entered into an agreement to acquire the remaining 30%
interest in Ets. Brancher S.A. in the first half of 2000 for 102.5 million
French francs, or approximately $17 million.

         The Company obtained control of Ets. Brancher S.A. on September 30,
1997, and, accordingly, began consolidating the financial position and operating
results of the subsidiary. The 30% interest in Ets. Brancher S.A. not owned by
the Company is reflected as minority interest on the accompanying consolidated
balance sheets and statements of income.

         The following table presents the unaudited pro forma results as if the
Company's 70% interest in Ets. Brancher had been consolidated beginning January
1, 1997 (in thousands, except per share data).

1998 DEALERS   In September 1998, the Company's Lennox Industries Inc.
subsidiary undertook a program of acquiring businesses ("the Dealers") that had
been retail outlets for the Company's and other manufacturers' products. In
1998, fourteen of these businesses (the "1998 Dealers") in Canada were purchased
for $22.9 million in cash. These acquisitions were accounted for in accordance
with the purchase method of accounting, and accordingly the purchase price was
allocated to the fair values of the assets acquired and liabilities assumed,
with the excess of $19.0 million being allocated to goodwill. The results of the
operations of the 1998 Dealers were fully consolidated with those of the Company
since the dates of acquisition.

HEARTH COMPANIES   During June and July 1998, the Company's Hearth Products Inc.
subsidiary, which is included in the North American residential segment,
purchased substantially all of the assets and certain liabilities of Superior
Fireplace Co. and all of the outstanding stock of Marco Mfg. Inc. and Pyro
Industries Inc. The aggregate purchase price for these acquisitions was $102.9
million, of which $99.1 million was in cash and $3.8 million was in the form of
a note payable in 1999. These acquisitions were accounted for in accordance with
the purchase method of


                                                                              41

accounting. Accordingly, the aggregate purchase price has been allocated to
assets totaling $131.5 million and to liabilities totaling $28.6 million of the
acquired companies based upon the fair value of those assets and liabilities. As
a result, the Company recorded goodwill of approximately $73.8 million which is
being amortized on a straight-line basis over 40 years. The results of
operations of the acquired Hearth companies have been fully consolidated with
those of the Company since the dates of acquisition.

HEATCRAFT DO BRASIL   During August 1998, the Company's Lennox Global Ltd.
subsidiary purchased 84% of the outstanding stock of Heatcraft do Brasil, a
Brazilian company engaged in the manufacture and sale of refrigeration,
automotive air conditioning equipment, and heat transfer products. The purchase
price of $20.5 million in cash has been allocated to the acquired assets and
liabilities based upon the fair value of those assets and liabilities and the
excess of $11.3 million has been allocated to goodwill, which is being amortized
on a straight-line basis over 40 years. The results of operations of Heatcraft
do Brasil have been consolidated with those of the Company since the date of
acquisition.

         The following table presents the unaudited pro forma results as if the
1998 Dealers, the Hearth companies, and Heatcraft do Brasil had been acquired on
January 1, 1997 (in thousands except per share data).

1999 DEALERS   In 1999, the Company acquired 46 additional Dealers in Canada
and 33 in the United States (the "1999 Dealers"), bringing the total number
acquired to 93. The cost to acquire the 1999 Dealers was $218.0 million, $209.1
million of which was paid in cash and $8.9 million of which was paid in shares
of the Company's stock (802,723 shares).

         Under the purchase method of accounting, $58.1 million was allocated to
the fair values of the assets and liabilities acquired and the excess of $159.9
million was allocated to goodwill, which is being amortized on a straight-line
basis over 40 years. The results of operations of the 1999 Dealers acquired have
been fully consolidated with the results of the Company since the various dates
of acquisition.

KIRBY   In June 1999, the Company acquired the outstanding stock of James N.
Kirby Pty. Ltd., an Australian manufacturer and distributor of refrigeration and
heat transfer products. The purchase price of $65.5 million was paid in cash and
in shares of the Company's common stock (650,430 shares) in the amounts of $49.4
million and $16.1 million, respectively. If Lennox common stock does not trade
at a price greater than $29.09 per share for five consecutive days from the
period from June 2000 to June 2001, then Lennox is obligated to pay the former
owners of Kirby the difference between the trading price for the last five days
of this period and $29.09 for 577,500 of the shares of Lennox common stock. The
acquisition was accounted for in accordance with the purchase method of
accounting, and accordingly, the purchase price was allocated, based on fair
value, to identifiable assets totaling $83.2 million and to liabilities totaling
$56.7 million with $39.0 million being allocated to goodwill. In order to
finance the cash portion of the purchase price, the Company borrowed
approximately $48.3 million in the form of three promissory notes. The first
promissory note of $16.1 million bore interest at 5.68% and was paid in December
1999 as part of a permanent financing arrangement. The second promissory note of
$11.4 million, which bore no interest, was paid in December 1999. The third
promissory note of $20.8 million is payable $11.0 million in 2001 and $9.8
million in 2002. The stated interest rate on the third promissory note escalates
from no interest in year one to 4% in year three. Accordingly, the Company
recorded a discount on the third promissory note of $2.3 million, which is being
amortized over three years, to record the promissory note at fair value. The
goodwill is being amortized on a straight-line basis over 40 years. In
conjunction with the acquisition, the Company assumed a $20.5 million promissory
note bearing interest at 5.5% which was paid upon the arranging of permanent
financing. The results of the operations of this acquired company have been
fully consolidated with those of the Company since the date of acquisition.

EXCEL COMFORT SYSTEMS   In October 1999 the Company, through its Excel Comfort
Systems subsidiary, purchased certain heating and air conditioning manufacturing
related assets from The Ducane Company, Inc. and a related company. Certain
related liabilities were also assumed. The cash purchase price of $52.8 million
was allocated, in accordance with the purchase method of accounting, to the fair
values of the assets ($40.9 million) and the liabilities ($8.2 million) with
$20.1 million being allocated to goodwill. This goodwill is being amortized on a
straight-line basis over 40 years. The results of operations of the Company
include, on a fully consolidated basis, the results of Excel Comfort Systems
since the assets were acquired.

         The Company has bank lines of credit aggregating $423 million, of which
$280 million was outstanding at December 31, 1999 and the remaining $143 million
was available for future borrowings. As of December 31, 1999, $258 million of
the amount outstanding has been classified as long-term debt in the accompanying
Consolidated Balance Sheets as the facility expires in July 2004. Included in
the lines is a $300 million domestic facility governed by the Revolving Credit
Facility Agreement. This agreement is between the Company and a syndicate of
banks providing the $300 million line. The facility contains certain financial
covenants and bears interest, at the Company's option, at a rate equal to either
(a) the greater of the bank's prime rate or the federal fund's rate plus 0.5% or
(b) the London Interbank Offered Rate plus a margin equal to 0.5% to 1.125%,
depending upon the ratio of total funded debt to EBITDA. The Company pays a
commitment fee equal to 0.15% to 0.30% of the unused commitment, depending upon
the ratio of total funded debt to EBITDA. The agreement provides restrictions on
the Company's ability to incur additional indebtedness, encumber its assets,
sell its assets, or pay dividends. (See Subsequent Events for information on
additional credit facilities).

         Deferred income taxes reflect the tax consequences on future years of
temporary differences between the tax basis of assets and liabilities and their
financial reporting basis and are reflected as current or noncurrent depending
on the timing of the expected realization. The deferred tax provision (benefit)
for the periods shown represents the effect of changes in the amounts of
temporary differences during those periods.

         The Company has net foreign operating loss carryforwards, mainly in
Europe, which expire at various dates in the future. All such loss carryforwards
have a full valuation allowance. The net change in the deferred tax asset
valuation reserve for the year ended December 31, 1999 was an increase of
$5,115. The increase is a result of increased foreign losses.

         No provision has been made for income taxes which may become payable
upon distribution of the foreign subsidiaries' earnings since management
considers substantially all of these earnings permanently invested. As of
December 31, 1999, the unrecorded deferred tax liability related to the
undistributed earnings of the Company's foreign subsidiaries was insignificant.

11. EMPLOYEE BENEFIT PLANS:

PROFIT SHARING PLANS   The Company maintains noncontributory profit sharing
plans for its eligible domestic salaried employees. These plans are
discretionary as the Company's contributions are determined annually by the
Board of Directors. Provisions for contributions to the plans amounted to $15.0
million, $13.6 million, and $11.5 million in 1999, 1998, and 1997, respectively.

EMPLOYEE BENEFITS TRUST   The Company also has an Employee Benefits Trust (the
"Trust") to provide eligible employees of the Company, as defined, with certain
medical benefits. Trust contributions are made by the Company as defined by the
Trust agreement.

EMPLOYEE STOCK PURCHASE PLAN   The Company has an employee stock purchase plan
under which 825,000 shares of common stock were reserved at December 31, 1999.
The shares are offered for sale to employees only, through payroll deductions,
at prices equal to 85% of the lesser of the fair market value of the Company's
common stock on the first day of the offering period or the last day of the
exercise period. For the twelve months ended December 31, 1999, participating
employees purchased 155,667 shares under the plan.

PENSION AND POSTRETIREMENT BENEFIT PLANS   The Company has domestic and foreign
pension plans covering substantially all employees. The Company makes annual
contributions to the plans equal to or greater than the statutory required
minimum. The Company also maintains an unfunded postretirement benefit plan
which provides certain medical and life insurance benefits to eligible
employees. The pension plans are accounted for under provisions of SFAS No. 87,
"Employers' Accounting for Pensions." The postretirement benefit plan is
accounted for under the provisions of SFAS No. 106, "Employers' Accounting for
Postretirement Benefits Other than Pensions."

         For measurement purposes, a 7.8% annual rate of increase in the per
capita cost of covered health care benefits was assumed for 1999. The rate was
assumed to decrease gradually to 5.0% by 2003 and remain at that level
thereafter.

         The benefit obligation and fair value of plan assets for the pension
plans with benefit obligations in excess of plan assets were approximately
$22,835,000 and $8,332,000, respectively, as of December 31, 1999, and
$12,478,000 and $3,607,000, respectively, as of December 31, 1998.

         Assumed health care cost trend rates have a significant effect on the

12. STOCK-BASED COMPENSATION PLANS:

STOCK OPTION AND RESTRICTED STOCK PLAN   The Company has a Stock Option and
Restricted Stock Plan, which was amended in September 1998 (the "1998 Incentive
Plan"). The 1998 Incentive Plan is accounted for under APB Opinion No. 25, under
which no compensation cost has been recognized. If the 1998 Incentive Plan had
been accounted for under the provisions of SFAS No. 123, "Accounting for
Stock-Based Compensation," the Company's net income (loss) would have been
adjusted to the following pro forma amounts (in thousands, except per share
data):

<TABLE>

                                            Years Ended December 31,

Basic earnings (loss) per share:
  As reported                        $     1.85   $     1.50   $    (0.99)
  Pro forma                                1.81         1.50        (1.05)
Diluted earnings (loss) per share:
  As reported                        $     1.81   $     1.47   $    (0.99)
  Pro forma                                1.77         1.47        (1.05)
                                     ----------   ----------   ----------
</TABLE>

         Because the method of accounting under SFAS No. 123 has not been
applied to options granted prior to January 1, 1995, the resulting pro forma
compensation cost may not be representative of that to be expected in future
years.

         Under the 1998 Incentive Plan, the Company is authorized to issue
options for 8,216,571 shares of common stock. As of December 31, 1999, options
for 7,377,146 shares of common stock have been granted and options for 831,336
shares have been cancelled or repurchased. Consequently, as of December 31,
1999, there are options for 1,670,761 shares available for grant. Under the 1998
Incentive Plan, the option exercise price equals the stock's fair value on the
date of grant. 1998 Incentive Plan options granted prior to 1998 vest on the
date of grant. 1998 Incentive Plan options granted in 1999 and 1998 vest over
three years. All 1998 Incentive Plan options expire after ten years.

         As of December 31, 1999, options to purchase 1,205,556 shares of common
stock with exercise prices ranging from $7.28 to $7.53, options to purchase
1,374,747 shares of common stock with exercise prices ranging from $13.21 to
$13.90 and options to purchase 371,250 shares of common stock with an exercise
price of $19.03 were exercisable. The fair value of each option granted in 1999
is estimated on the date of grant based on a risk-free interest rate of 6.5%,
volatility of 19%, expected life of ten years and an expected dividend yield of
4%. The fair value of each option granted in 1998 and 1997 is estimated on the
date of grant based on a risk-free interest rate of 6%, expected life of ten
years, and an expected dividend yield of 2%.

LONG-TERM INCENTIVE PLAN   Prior to 1999 the Company provided a long-term
incentive plan, the Lennox International Inc. Performance Share Plan (the
"Performance Plan") to certain employees. During 1998, the Company terminated
the Performance Plan. Under the Performance Plan, participants earned shares of
the Company's common stock in accordance with a discretionary formula
established by the Board of Directors based on the Company's performance over a
three-year period. The value of the shares earned was determined using an
independent appraisal. Under the Performance Plan 174,669 shares and 239,019
shares earned in fiscal 1997 and 1996, respectively, were issued in 1998 and
1997, respectively. During 1998, 358,974 shares were earned and issued in the
same year. Compensation expense recognized under the Performance Plan was
$6,876,335 and $2,259,616 for the years ended December 31, 1998 and 1997,
respectively, based on the fair value of the shares earned.

         During 1999, the Company established a new performance share plan (the
"New Performance Share Plan"). Under the New Performance Share Plan, performance
shares are awarded (the "Fixed Performance Awards") to certain employees at the
discretion of the board of directors as of the beginning of each fiscal year.
After ten


                                                                              49

<PAGE>   32

years of employment (the "Vesting Period"), the Fixed Performance Awards are
converted to an equal number of shares of the Company's common stock. If certain
pre-defined performance measures are met by the Company over a three-year
period, the Vesting Period is accelerated from ten years to three years for 25%
to 100% of the Fixed Performance Awards granted, depending on the Company's
performance. Compensation expense is measured based on the market price of the
stock at date of grant and is recognized on a straight-line basis over the
performance period. The weighted-average grant-date fair value for Fixed
Performance Awards granted in 1999 was $18.75 per share. The 46,161,607 shares
of common stock issued as of December 31, 1999, include 407,715 shares which
represent Fixed Performance Awards that have not yet vested and 52,899 shares
which represent Fixed Performance Awards which have vested but have not been
converted to shares of the Company's common stock.

         Under the New Performance Share Plan, plan participants may also earn
additional shares of the Company's common stock (the "Variable Performance
Awards"). The number of additional shares can range from 0% to 100% of the Fixed
Performance Awards granted, depending on the Company's performance over a
three-year period. There are no additional vesting requirements once the
Variable Performance Awards have been earned. Compensation expense is measured
by applying the market price of the Company's stock at the end of the period to
the number of Variable Performance Awards that are expected to be earned. Such
expense is recognized over the performance period. As of December 31, 1999,
81,952 Variable Performance Awards were expected to be earned in future periods
and related compensation expense of approximately $270,000 was recorded during
1999.

13. COMMITMENTS AND CONTINGENCIES:

OPERATING LEASES   The Company has various leases relating principally to the
use of operating facilities. Rent expense for 1999, 1998 and 1997 was
approximately $38.4 million, $28.2 million and $23.2 million, respectively.

         The approximate minimum commitments under all noncancelable leases at
December 31, 1999, are as follows (in thousands):

LITIGATION   The Company is involved in various claims and lawsuits incidental
to its business. In the opinion of management, these claims and suits in the
aggregate will not have a material adverse effect on the Company's business,
financial condition or results of operations.

14. EARNINGS PER SHARE:

Basic earnings per share are computed by dividing net income by the weighted
average number of common shares outstanding during the period. Diluted earnings
per share are computed by dividing net income by the sum of the

16. TREASURY STOCK:

On November 1, 1999, the Company's Board of Directors authorized the purchase of
up to 5,000,000 shares of the issued and outstanding common stock. As of
December 31, 1999 the Company had purchased 1,172,200 of such shares at a total
cost of $12.4 million.

17. RECENT ACCOUNTING PRONOUNCEMENTS:

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards for derivative instruments, including certain derivatives
embedded in other contracts (collectively referred to as derivatives) and for
hedging activities. This statement, for the Company, is effective with the first
quarter of 2001. The Company does not believe that the adoption of this
pronouncement will have a significant impact on the Company's financial
statements.

Investment, LLC owns 70% of AOC Development II, LLC. AOC Development II, LLC has
constructed a new office building and the Company is leasing part of it for use
in conjunction with the Company's corporate headquarters. The lease has a term
of 25 years and the annual lease payments are approximately $2.6 million per
year for the first five years. The Company believes that the terms of the lease
with AOC Development II, LLC are at least as favorable as could be obtained from
unaffiliated third parties.

19. SUBSEQUENT EVENTS (UNAUDITED):

On January 25, 2000, the Company entered into an agreement with a syndicate of
banks which added a $300 million revolving credit facility, bringing the
domestic short-term credit facilities to a total of $600 million. Terms and
conditions under this agreement are substantially identical to those of the $300
million agreement discussed in Note 8 - Long-Term Debt and Lines of Credit,
except that the new $300 million agreement expires on January 18, 2001.

         On January 21, 2000 the Company completed its acquisition of Service
Experts, Inc., a holding company owning Dealers of the type previously purchased
by the Company. The acquisition took place in the form of a merger whereby .67
shares of Lennox International Inc. common stock were exchanged for each
outstanding share of Service Experts, Inc. The shares so exchanged were valued
at approximately $140.0 million. In addition, the Company assumed approximately
