                               PROSPECTUS SUMMARY

     You should read the following summary together with the more detailed
information and our financial statements and notes appearing elsewhere in this
prospectus.

                                     LENNOX

     We are a leading global provider of climate control solutions and had 1998
net sales of $1.8 billion. We design, manufacture and market a broad range of
products for the heating, ventilation, air conditioning and refrigeration
markets, which is sometimes referred to as "HVACR." Our products are sold under
well-established brand names including "Lennox", "Armstrong Air", "Bohn",
"Larkin", "Heatcraft" and others. We have recently initiated a program to
acquire dealers in metropolitan areas in the U.S. and Canada so we can provide
heating and air conditioning products and services directly to consumers.

     Our furnaces, heat pumps, air conditioners, pre-fabricated fireplaces and
related products are available in a variety of designs, efficiency levels and
price points that provide an extensive line of comfort systems. A majority of
our sales of residential heating and air conditioning products in the U.S. and
Canada are to the repair and replacement market, which is less cyclical than the
new construction market. We also provide a range of air conditioning products
for commercial market applications such as mid-size office buildings,
restaurants, churches and schools. Our commercial refrigeration products are
used primarily in cold storage applications for food preservation in
supermarkets, convenience stores, restaurants, warehouses and distribution
centers. Our heat transfer products are used by us in our HVACR products and
sold to third parties.

     We market our products using multiple brand names and distribute our
products through multiple distribution channels to penetrate different segments
of the HVACR market. Our "Lennox" brand of residential heating and air
conditioning products is sold directly through approximately 6,000 installing
dealers -- the "one-step" distribution system -- which has created strong and
long-term relationships with our dealers in North America. Our "Armstrong Air",
"Air-Ease", "Concord" and "Magic-Pak" residential heating and air conditioning
brands are sold to regional distributors that in turn sell the products to
installing contractors -- the "two-step" distribution system typically utilized
in the heating and air conditioning industry. The acquisition of heating and air
conditioning dealers in Canada and the planned acquisition of dealers in the
U.S. allows us to participate in the retail sale and service of heating and air
conditioning products. Our hearth products, commercial air conditioning products
and refrigeration products are also sold under multiple brand names and through
a combination of wholesalers, contractors, original equipment manufacturers,
manufacturers' representatives and national accounts.

COMPETITIVE STRENGTHS

     We have a combination of strengths that position us to continue to be a
leading provider of climate control solutions, including:

     - strong brand recognition and reputation, particularly with the well
       recognized "Lennox" name;

     - one of the broadest distribution systems of any major HVACR manufacturer;

     - leading heat transfer design and manufacturing expertise;

     - commitment to product innovation and technological leadership; and

     - demonstrated manufacturing efficiency for our products.

GROWTH STRATEGY

     Our growth strategy is designed to capitalize on our competitive strengths
in order to expand our market share and profitability in the worldwide HVACR
markets. We will continue to pursue internal programs and

                                        4
<PAGE>   5

strategic acquisitions that broaden our product and service offerings, expand
our market opportunities and enhance our technological expertise. The key
elements of this strategy include:

     - expanding our market opportunities in North America through a series of
       initiatives, including the acquisition of heating and air conditioning
       dealers;

     - exploiting international opportunities through acquisitions and internal
       growth;

     - increasing our presence in the hearth products market by selling in the
       distribution channels we acquired and through our historical distribution
       channels; and

     - continuing to invest in research and new product development.
                             ---------------------

RECENT EVENTS

     On April 6, 1999, we filed a registration statement for our initial public
offering of our common stock. We plan to sell           shares of our common
stock and selling stockholders plan to sell           shares of common stock at
an estimated price range of $          to $     per share. We estimate that we
will receive net proceeds from this offering of approximately $     million, all
of which we will use to repay borrowings under our revolving credit facility and
term credit agreement.
                             ---------------------

     We are located at 2100 Lake Park Blvd., Richardson, Texas 75080 and our
telephone number is (972) 497-5000.

                                  THE OFFERING

     We may offer and issue the           shares of our common stock covered by
this prospectus from time to time in business combination transactions involving
our acquisition, directly or indirectly, of businesses or other operating
assets. We expect that we will determine the terms of these acquisitions by
direct negotiations with the owners or controlling persons of the businesses or
assets to be acquired and the shares of our common stock issued will be valued
at prices reasonably related to market prices prevailing either at the time an
acquisition agreement is executed or at or about the time of delivery of the
shares.

                        SUMMARY FINANCIAL AND OTHER DATA

     The following summary financial and other data for each of the years ended
December 31, 1996, 1997 and 1998 have been derived from our audited financial
statements included elsewhere in this prospectus. The summary financial and
other data for each of the three months ended March 31, 1998 and 1999 are
derived from our unaudited financial statements which, in our opinion, have been
prepared on the same basis as the audited financial statements and include all
adjustments, consisting of normal recurring adjustments, necessary for a fair
presentation of this information. Our fiscal quarters are each comprised of 13
weeks. For convenience, the 13-week periods ended April 4, 1998 and April 3,
1999 are referred to as the three months ended March 31, 1998 and 1999,
respectively. Effective September 30, 1997 we increased our ownership of Ets.
Brancher S.A., our European joint venture, from 50% to 70% and, accordingly,
changed our accounting method of recognizing this investment from the equity
method to the consolidation method. You should read "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and our financial
statements and notes included elsewhere in this prospectus for a further
explanation of the financial data summarized here.

(1) Represents a pre-tax charge taken in the fourth quarter of 1997 for
    estimated costs of an inspection program for our Pulse furnaces installed
    from 1982 to 1990 in the U.S. and Canada. We initiated the inspection
    program because we received anecdotal reports of accelerated corrosion of a
    component of these products under extreme operating conditions. We
    periodically review the reserve balance and at this time we believe the
    remaining reserve of $13.6 million at March 31, 1999 will be adequate to
    cover the remaining costs associated with this inspection program. This
    program ends on June 30, 1999.

                                  RISK FACTORS

     You should carefully consider the risks described below before making an
investment decision.

RISK FACTORS RELATING TO OUR BUSINESS

     Our business is subject to the following risks, which include risks
relating to the industry in which we operate.

    WE MAY INCUR MATERIAL COSTS AS A RESULT OF WARRANTY AND PRODUCT LIABILITY
    CLAIMS WHICH WOULD NEGATIVELY IMPACT OUR PROFITABILITY

     The development, manufacture, sale and use of our products involve a risk
of warranty and product liability claims. In addition, as we increase our
efforts to acquire installing heating and air conditioning dealers in the U.S.
and Canada, we incur the risk of liability claims for the installation and
service of heating and air conditioning products. We maintain product liability
insurance. Our product liability insurance policies have limits, however, that
if exceeded, may result in material costs that would have an adverse effect on
our future profitability. In addition, warranty claims are not covered by our
product liability insurance and there may be types of product liability claims
that are also not covered by our product liability insurance.

    WE MAY NOT BE ABLE TO REALIZE OUR BUSINESS STRATEGY OF SUCCESSFULLY
    COMPLETING OR OPERATING STRATEGIC ACQUISITIONS

     We intend to grow in part through the acquisition of heating and air
conditioning dealers and other complementary businesses both in the U.S. and
internationally. This strategy will involve reviewing and potentially
reorganizing the operations, corporate infrastructure and systems and financial
controls of acquired businesses. The success of our acquisition strategy may be
limited because of unforeseen expenses, difficulties, complications and delays
encountered in connection with the expansion of our operations through
acquisitions. We may not be able to acquire or manage profitably additional
businesses or to integrate successfully any acquired businesses into our
business without substantial costs, delays or other operational or financial
difficulties. In addition, we may be required to incur additional debt or issue
equity to pay for future acquisitions.

    WE ARE ENTERING NEW BUSINESSES IN WHICH WE HAVE LIMITED EXPERIENCE AND WE
    MAY NOT BE ABLE TO SUCCESSFULLY MANAGE OR OPERATE THESE NEW BUSINESSES

     With our recently initiated program of acquiring heating and air
conditioning dealers and with our recent acquisitions of hearth products
manufacturers, we have entered into new lines of business. We cannot assure you
that we will be able to successfully manage or operate these new businesses.

     THE CONSOLIDATION OF DISTRIBUTORS AND DEALERS COULD FORCE US TO LOWER OUR
     PRICES OR HURT OUR BRAND NAMES WHICH WOULD RESULT IN LOWER SALES

     There is currently an effort underway in the U.S. by several companies to
purchase independent distributors and dealers and consolidate them into large
enterprises. These large enterprises may be able to exert pressure on us or our
competitors to reduce prices. Additionally, these new enterprises tend to
emphasize their company name, rather than the brand of the manufacturer, in
their promotional activities, which could lead to dilution of the importance and
value of our brand names. Future price reductions and the brand dilution caused
by the consolidation among HVACR distributors and dealers could have an adverse
effect on our future sales and profitability.

     OUR DEALER ACQUISITION PROGRAM COULD LEAD TO LOSS OF SALES FROM INDEPENDENT
     DEALERS AND DEALERS OWNED BY CONSOLIDATORS

     With our recently initiated program of acquiring heating and air
conditioning dealers in the U.S. and Canada, we face the risk that dealers owned
by consolidators and independent dealers may discontinue using

                                        7
<PAGE>   8

our heating and air conditioning products because we are and increasingly will
be in competition with them. We sold approximately $50 million of heating and
air conditioning products to consolidators in 1998, representing 2.7% of our net
sales.

     COOLER THAN NORMAL SUMMERS AND WARMER THAN NORMAL WINTERS MAY DEPRESS OUR
     SALES

     Demand for our products and for our services is strongly affected by the
weather. Hotter than normal summers generate strong demand for our replacement
air conditioning and refrigeration products and colder than normal winters have
the same effect on our heating products. Conversely, cooler than normal summers
and warmer than normal winters depress our sales. Because a high percentage of
our overhead and operating expenses are relatively fixed throughout the year,
operating earnings and net earnings tend to be lower in quarters with lower
sales.

     WE MAY NOT BE ABLE TO COMPETE FAVORABLY IN THE HIGHLY COMPETITIVE HVACR
     BUSINESS

     Competition in our various markets could cause us to reduce our prices or
lose market share, or could negatively affect our cash flow, which could have an
adverse effect on our future financial results. Substantially all of the markets
in which we participate are highly competitive. The most significant competitive
factors we face are product reliability, product performance, service and price,
with the relative importance of these factors varying among our product lines.
In addition, in our new distribution channel in which we will sell our products
directly to consumers, we face competition from independent dealers and dealers
owned by consolidators and utility companies, some of whom may be able to
provide their products or services at lower prices than we can.

    WE MAY BE ADVERSELY AFFECTED BY PROBLEMS IN THE AVAILABILITY OF OR INCREASES
    IN THE PRICES OF COMPONENTS AND RAW MATERIALS

     Increases in the prices of raw materials or components or problems in their
availability could depress our sales or increase the costs of our products. We
are dependent upon components purchased from third parties as well as raw
materials such as copper, aluminum and steel. We enter into contracts each year
for the supply of key components at fixed prices. However, if a key supplier is
unable or unwilling to meet our supply requirements, we could experience supply
interruptions or cost increases, either of which could have an adverse effect on
our gross profit. In addition, we regularly pre-purchase a portion of our raw
materials at a fixed price each year to hedge against price fluctuations, but a
large increase in raw materials prices could significantly increase the cost of
our products.

    THE PROFITABILITY OF OUR INTERNATIONAL OPERATIONS COULD BE ADVERSELY
    AFFECTED BY ECONOMIC TURMOIL, WAR OR CIVIL UNREST

     Our international operations are subject to various economic, political and
other risks that are generally not present in our North American operations.
International risks include:

     - instability of foreign economies and governments;

     - price and currency exchange controls;

     - unfavorable changes in monetary and tax policies and other regulatory
       changes;

     - fluctuations in the relative value of currencies;

     - expropriation and nationalization of our foreign assets; and

     - war and civil unrest.

     We sell products in over 70 countries and have business units located in
Europe, Asia Pacific, Latin America and Mexico. Sales of our products outside of
the U.S. represented approximately 19.2% of our 1998 net sales. We anticipate
that, over time, international sales will continue to grow as a percentage of
our total sales.

                                        8
<PAGE>   9

    OUR OPERATIONS ARE SUBJECT TO INHERENT RISKS THAT COULD RESULT IN LOSS OF
    LIFE OR SEVERE DAMAGE TO OUR PROPERTIES AND THE SUSPENSION OF OPERATIONS

     Our operations are subject to hazards and risks inherent in operating large
manufacturing facilities, including fires, natural disasters and explosions, all
of which can result in loss of life or severe damage to our properties and the
suspension of operations. We maintain business interruption and other types of
property insurance as protection against operating hazards. The occurrence of a
significant event not fully covered by insurance could have an adverse effect on
our profitability.

     SINCE A SIGNIFICANT PERCENTAGE OF OUR WORKFORCE IS UNIONIZED, WE FACE RISKS
     OF WORK STOPPAGES AND OTHER LABOR RELATIONS PROBLEMS

     We are subject to a risk of work stoppage and other labor relations matters
because a significant percentage of our workforce is unionized. As of December
31, 1998, approximately 30% of our workforce was unionized. Within the U.S., we
currently have eight manufacturing facilities and five distribution centers,
along with our North American Parts Center in Des Moines, Iowa, with collective
bargaining agreements ranging from three to eight years in length. Of our
significant manufacturing facilities, the contract at our Lynwood, California
facility expires in December 1999. Following the expiration of the collective
bargaining agreement in April 1999, we experienced a work stoppage at our
Bellevue, Ohio factory for three weeks in May 1999. This facility has a new
collective bargaining agreement that expires April 2002. Outside of the U.S., we
have 12 significant facilities that are represented by unions. The agreement for
our manufacturing facility in Toronto, Ontario expired in April 1999 and the
agreement for our facility in Laval, Quebec expires in December 1999. As has
been the case in the past, the employees at our Toronto facility are continuing
to work under the expired contract pending negotiation of a new agreement. As we
expand our operations, we are subject to increased unionization of our
workforce. The results of future negotiations with these unions, including the
effects of any production interruptions or labor stoppages, could have an
adverse effect on our future financial results. You should read
"Business -- Employees" for a more complete discussion of our collective
bargaining agreements.

    EXPOSURE TO ENVIRONMENTAL LIABILITIES COULD ADVERSELY AFFECT OUR RESULTS OF
    OPERATIONS

     Our future profitability could be adversely affected by current or future
environmental laws. We are subject to extensive and changing federal, state and
local laws and regulations designed to protect the environment in the U.S. and
in other parts of the world. These laws and regulations could impose liability
for remediation costs or result in civil or criminal penalties in cases of
non-compliance. Compliance with environmental laws increases our costs of doing
business. Because these laws are subject to frequent change, we are unable to
predict the future costs resulting from environmental compliance.

     The U.S. and other countries have established programs for limiting the
production, importation and use of certain ozone depleting chemicals, including
refrigerants used by us in most of our air conditioning and refrigeration
products. Some categories of these refrigerants have been banned completely and
others are currently scheduled to be phased out in the U.S. by the year 2030.
The U.S. is under pressure from the international environmental community to
accelerate the current 2030 deadline. In Europe, this phaseout may occur even
sooner. The industry's failure to find suitable replacement refrigerants for
substances that have been or will be banned or the acceleration of any phase out
schedules for these substances by governments could have an adverse effect on
our future financial results. You should read "Business -- Regulation" for a
more complete discussion of environmental regulations which affect our business.

     WE MAY BE ADVERSELY IMPACTED BY THE YEAR 2000 AND THE CONVERSION OF OUR
     MANAGEMENT INFORMATION SYSTEMS TO DISTRIBUTED PROCESSING SYSTEMS

     Year 2000 problems might require us to incur unanticipated expenses or
experience interruptions of operations that could have an adverse effect on our
future sales and profitability. In 1996, we began converting all of our major
domestic management information systems from mainframe systems to distributed
processing systems. In order to avoid disruption to our operations, we have
conducted the conversion on a phased basis.

                                        9
<PAGE>   10

We anticipate that our major domestic operations will be supported by
distributed processing by the end of 1999. In addition, we have and will
continue to make investments in our computer systems and applications in an
effort to ensure that they are Year 2000 compliant. However, we may experience
interruptions of operations because of problems in implementing distributed
processing or because of Year 2000 problems within our company. Our suppliers or
customers might experience Year 2000 problems. You should read "Management's
Discussion and Analysis of Financial Condition and Results of Operations -- Year
2000 Compliance" and "Business -- Information Systems" for a more complete
discussion of our systems upgrade and Year 2000 compliance initiative.

     THE NORRIS FAMILY WILL BE ABLE TO EXERCISE SIGNIFICANT CONTROL OVER OUR
     COMPANY

     The ability of the Norris family to exercise significant control over
Lennox may discourage, delay or prevent a takeover attempt that a stockholder
might consider in his or her best interest and that might result in a
stockholder receiving a premium for his or her common stock. Following the
closing of the offering, approximately 110 descendants of or persons otherwise
related to D.W. Norris, one of our original owners, will be able to collectively
control      % of the outstanding shares of our common stock. Accordingly, if
the Norris family were to act together, it would have the ability to:

     - control the vote of most matters submitted to our stockholders, including
       any merger, consolidation or sale of all or substantially all of our
       assets;

     - elect all of the members of our board of directors;

     - prevent or cause a change in control of our company; and

     - decide whether to issue additional common stock or other securities or
       declare dividends.

RISK FACTORS RELATING TO SECURITIES MARKETS

     There are risks relating to the securities markets that you should consider
in connection with your investment in and ownership of our stock.

     ANTI-TAKEOVER PROVISIONS IN OUR GOVERNING DOCUMENTS AND DELAWARE LAW COULD
     PREVENT OR DELAY A CHANGE IN CONTROL OF OUR COMPANY

     Our governing documents contain provisions that make it more difficult to
implement corporate actions that may have the effect of delaying, deterring or
preventing a change in control. A stockholder might consider a change in control
in his or her best interest because he or she might receive a premium for his or
her common stock. Examples of these provisions include:

     - a vote of more than 80% of the outstanding voting stock is required for
       stockholders to amend specified provisions of the governing documents;

     - our board of directors is divided into three classes, each serving
       three-year terms;

     - members of our board of directors may be removed only for cause and only
       upon the affirmative vote of at least 80% of the outstanding voting
       stock; and

     - a vote of more than 80% of the outstanding voting stock is required to
       approve specified transactions between us and any person or group that
       owns at least 10% of our voting stock.

     Our board of directors has the ability, without stockholder action, to
issue shares of preferred stock that could, depending on their terms, delay,
discourage or prevent a change in control of Lennox. In addition, the Delaware
General Corporation Law, under which we are incorporated, contains provisions
that impose restrictions on business combinations such as mergers between us and
a holder of 15% or more of our voting stock. You should read the "Description of
Capital Stock" section for a more complete description of these provisions.

                                       10
<PAGE>   11

     A SUBSTANTIAL NUMBER OF OUR SHARES WILL BE AVAILABLE FOR SALE IN THE PUBLIC
     MARKET AFTER THE OFFERING AND SALES OF THOSE SHARES COULD ADVERSELY AFFECT
     OUR STOCK PRICE

     Sales of a substantial number of shares of our common stock into the public
market or the perception that these sales could occur, could adversely affect
our stock price or could impair our ability to obtain capital through an
offering of equity securities. After our initial public offering, we will have
outstanding           shares of common stock. Of these shares, the        shares
sold in our initial public offering will be freely tradeable without restriction
or further registration under the Securities Act of 1933, except for any shares
purchased by our "affiliates" as that term is defined by Rule 144. The remaining
          shares of common stock outstanding, which will represent   % of the
total outstanding shares of common stock, will be "restricted" as that term is
defined by Rule 144. You should read the "Shares Eligible For Future Sale"
section for a more complete discussion of these matters.

    THE PRICE OF OUR COMMON STOCK MAY FLUCTUATE SIGNIFICANTLY AND YOU COULD LOSE
    ALL OR PART OF YOUR INVESTMENT AS A RESULT

     The price of our common stock may be affected by a number of factors,
including:

     - actual or anticipated fluctuations in our operating results;

     - changes in expectations as to our future financial performance or changes
       in financial estimates of securities analysts;

     - announcements of new products or technological innovations; and

     - the operating and stock price performance of other comparable companies.

     In addition, the stock market in general has experienced extreme volatility
that often has been unrelated to the operating performance of particular
companies. These broad market and industry fluctuations may adversely affect the
trading price of our common stock, regardless of our actual operating
performance.

                          PRICE RANGE OF COMMON STOCK

     Upon consummation of our initial public offering, our common stock will be
traded on the New York Stock Exchange under the trading symbol "LII." As of
            , 1999,           shares of our common stock were outstanding and
held by approximately           stockholders of record. The number of record
holders does not bear any relationship to the number of beneficial owners of
common stock.

                                DIVIDEND POLICY

     We paid cash dividends of $     , $     and $     per share on our common
stock during 1996, 1997 and 1998, respectively. We anticipate that we will
continue to pay cash dividends on our common stock, but any future determination
as to the payment or amount of dividends will depend upon our future results of
operations, capital requirements, financial condition and other factors as our
board of directors may consider. In addition, our revolving credit facility,
term credit agreement and our other debt instruments prohibit the payment of
dividends unless we can incur $1.00 of additional indebtedness according to the
terms of these instruments. For more information about our debt instruments, see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

                       SELECTED FINANCIAL AND OTHER DATA

     The following selected financial and other data for each of the years in
the five-year period ended December 31, 1998 have been derived from our
financial statements which have been audited by Arthur Andersen LLP. The summary
financial and other data for each of the three months ended March 31, 1998 and
1999 are derived from our unaudited financial statements which, in our opinion,
have been prepared on the same basis as the audited financial statements and
include all adjustments, consisting of normal recurring adjustments, necessary
for a fair presentation of such information. Our fiscal quarters are each
comprised of 13 weeks. For convenience, the 13-week periods ended April 4, 1998
and April 3, 1999 are referred to as the three months ended March 31, 1998 and
1999, respectively. Effective September 30, 1997 we increased our ownership of
Ets. Brancher, our European joint venture, from 50% to 70% and, accordingly,
changed our accounting method of recognizing this investment from the equity
method to the consolidation method. You should read "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and our financial
statements and notes included elsewhere in this prospectus for a further
explanation of the financial data summarized here.

    estimated costs of an inspection program for our Pulse furnaces installed
    from 1982 to 1990 in the U.S. and Canada. We initiated the inspection
    program because we received anecdotal reports of accelerated corrosion of a
    component of these products under extreme operating conditions. We
    periodically review the reserve balance and at this time we believe the
    remaining reserve of $13.6 million at March 31, 1999 will be adequate to
    cover the remaining costs associated with this inspection program. This
    program ends on June 30, 1999.

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

OVERVIEW

     We participate in four reportable business segments of the HVACR industry.
The first segment is the North American residential market in which we
manufacture and market a full line of heating, air conditioning and hearth
products for the residential replacement and new construction markets in the
U.S. 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 we
manufacture and sell 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
we design, manufacture and sell evaporator and condenser coils, copper tubing
and related manufacturing equipment to original equipment manufacturers and
other specialty purchasers on a global basis.

     We sell our products to numerous types of customers, including
distributors, installing dealers, homeowners, national accounts and original
equipment manufacturers. The demand for our products is cyclical and 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 our 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 our manufacturing processes are copper, aluminum
and steel. In instances where we are unable to pass on to our customers
increases in the costs of copper and aluminum, we enter into forward contracts
for the purchase of such materials. We have forward commitments for the
substantial majority of our internal needs of aluminum through December 1999 and
copper through December 2000. We attempt 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 our needs
throughout the year. These hedging strategies enable us to establish product
prices for the entire model year while minimizing the impact of price increases
of components and raw materials on our margins. Warranty expense is estimated
based on historical trends and other factors.

     Following the expiration of the collective bargaining agreement in April
1999, we experienced a work stoppage at our Bellevue, Ohio factory for three
weeks in May 1999. This factory manufactures our "Armstrong Air" brand of
residential heating and air conditioning products for the North American market.
We had accumulated additional inventory levels in anticipation of a possible
work stoppage. Through the use of management personnel we continued limited
production from this factory during this period. As a result, we were generally
able to meet the majority of our customer orders. We do not believe that we
suffered any damage to our relationships with our customers. We do not expect
that this work stoppage will have a material adverse effect on our results of
operations for the second quarter of 1999. On May 20, 1999, the union at the
Bellevue, Ohio factory ratified a new collective bargaining agreement that
expires April 2002 and this factory resumed full production within two business
days.

     In September 1997, we increased our ownership in Ets. Brancher from 50% to
70%. As a result, we assumed control of the venture and began consolidating the
financial position and operating results of the venture in the fourth quarter of
1997. Previously, we used the equity method of accounting for our investment in
this entity. In the fourth quarter of 1998, we restructured our ownership of our
various European entities to allow for more efficient transfer of funds and to
provide for tax optimization. Although our European operations contributed to
revenue, they had an operating loss in 1997, 1998 and the first quarter of 1999,

                                       15
<PAGE>   16

primarily due to the performance of the commercial air conditioning business. In
the second half of 1998, we commenced and substantially completed the
installation of a new management team for our European operations. We are in the
process of bringing our manufacturing and operating expertise to the European
businesses.

     We 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 us one of the broadest
lines of hearth products in the industry. These businesses had aggregate
revenues of approximately $150 million in 1998, $68.6 million of which was
reflected in our 1998 net sales.

     We 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 $67 million in cash, common stock and
seller financing. In addition, we assumed approximately $28 million of Kirby's
debt. Kirby had revenues of approximately $71 million and $89 million for the
twelve months ended June 30, 1998 and the nine months ended March 31, 1999,
respectively.

     We recently initiated a program to acquire high quality heating and air
conditioning dealers in metropolitan areas in the U.S. and Canada to market
"Lennox" and other brands of heating and air conditioning products. This
strategy will enable us to extend our distribution directly to the consumer and
permit us to participate in the revenues and margins available at the retail
level while strengthening and protecting our brand equity. We believe 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 U.S. is comprised of over 30,000 dealers. In addition, we believe
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 May 31, 1999, we had acquired 43 dealers in Canada for an
aggregate purchase price of approximately $62 million and had signed letters of
intent to acquire 14 additional Canadian dealers and eight U.S. dealers for an
aggregate purchase price of approximately $47 million. As we acquire more
heating and air conditioning dealers, we expect that we will incur additional
costs to expand our infrastructure to effectively manage these businesses.

     We have assigned a 40-year life to the goodwill acquired in the
acquisitions of the hearth products companies and the dealers acquired to date.
These companies and dealers are all profitable and all have been in business for
extended periods of time. They all operate in established industries where the
basic product technology has changed very little over time. In addition, all of
these companies and dealers have strong brand names and market share in their
respective industries or markets. Based upon these factors, we concluded that
the anticipated future cash flows associated with the goodwill recognized in the
acquisitions will continue for at least 40 years.

     Our fiscal year ends on December 31 of each year, and our 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.

     Net sales. Net sales increased $109.4 million, or 28.8%, to $489.0 million
for the three months ended March 31, 1999 from $379.6 million for the three
months ended March 31, 1998.

     Net sales related to the North American residential segment were $284.9
million during the three months ended March 31, 1999, an increase of $81.3
million, or 39.9%, from $203.6 million for the corresponding three months in
1998. Of the $81.3 million increase, $35.9 million was due to sales from the
hearth products acquisitions which occurred in the third quarter of 1998 and the
first quarter of 1999, $16.7 million was due to sales from our Canadian dealers
and $5.5 million was due to sales from acquired heating and air conditioning
distributors. The remaining $23.2 million increase in North American residential
net sales was primarily due to an 11.4% increase in sales of our existing
businesses, almost all of which resulted from increased sales volumes,
principally caused by three factors. First, the hot summer in 1998 depleted the
inventory levels at our distributors and they increased their purchases in the
first quarter of 1999 to refill their inventories. Second, we offered our
Armstrong distributors preferential credit terms to encourage them to accumulate
inventory in

                                       17
<PAGE>   18

anticipation of a possible work stoppage at our Bellevue, Ohio factory. Third,
our volume increased as a result of sales to new dealers, which were added as a
result of programs to expand our dealer base.

     Commercial air conditioning net sales increased $10.7 million, or 13.1%, to
$92.5 million for the three months ended March 31, 1999 compared to the
corresponding three months in 1998. Of this increase, $8.5 million was due to
increased sales volumes in North America primarily due to the effectiveness of
recently established commercial sales districts. Net sales related to the
commercial refrigeration segment were $61.6 million during the three months
ended March 31, 1999, an increase of $13.7 million, or 28.6%, from $47.9 million
for the corresponding three months in 1998. McQuay do Brasil, which we acquired
in September 1998, contributed $3.3 million to commercial refrigeration revenues
in the first quarter of 1999 and Lovelock Luke Pty. Limited, which we acquired
in December 1998, contributed $10.5 million. North American commercial
refrigeration sales increased $3.3 million primarily due to strong sales volumes
to our supermarket customers and increased activity with our large distributors,
while sales in Europe decreased $3.4 million as compared to the prior period
principally due to reduced sales in Russia and Eastern Europe. Heat transfer
revenues increased $3.7 million, or 8.0%, to $50.0 million for the three months
ended March 31, 1999 compared to the corresponding three months in 1998. This
increase was primarily due to increased sales volumes to original equipment
manufacturers in North America.

     Domestic sales increased $78.3 million, or 25.7%, to $383.1 million for the
first quarter of 1999 from $304.8 million for the first quarter of 1998.
International sales increased $31.1 million, or 41.6%, to $105.9 million for the
first quarter of 1999 from $74.8 million for the first quarter of 1998. Sales in
Brazil for the first quarter of 1999 were $3.3 million but would have been
approximately $6.5 million if devaluation of the Brazilian currency had not
occurred in this quarter. As a result of the devaluation, we had to reduce the
carrying value of our Brazilian investment by $5.9 million, thereby causing a
reduction in our investments in joint ventures on our balance sheet.

     Gross profit. Gross profit was $151.6 million for the three months ended
March 31, 1999 as compared to $117.8 million for the three months ended March
31, 1998, an increase of $33.8 million. Gross profit margin was 31.0% for both
the three months ended March 31, 1999 and 1998. The increase of $33.8 million in
gross profit was primarily attributable to increased sales in the 1999 period as
compared to 1998. Gross profit margin remained unchanged for the 1999 period
because there were no substantive price increases for our products for the 1999
period, and improvements due to lower raw material costs, improved manufacturing
processes and increased overhead absorption associated with higher volumes of
sales were offset by increases in labor and overhead costs.

     Selling, general and administrative expenses. Selling, general and
administrative expenses were $129.3 million for the three months ended March 31,
1999, an increase of $32.0 million, or 32.9%, from $97.3 million for the three
months ended March 31, 1998. Selling, general and administrative expenses
represented 26.5% and 25.6% of total net revenues for the first three months of
1999 and 1998, respectively. Of the $32.0 million increase, $18.5 million, or
57.8%, was related to increased infrastructure associated with acquisitions. Of
the remaining $13.5 million increase, $9.5 million 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. The remaining $4.0 million increase in selling, general and
administrative expenses for the 1999 period related primarily to infrastructure
investments in Europe and Asia and normal inflationary adjustments.

     Other operating expense, net. Other operating expense, net totaled $2.5
million for the three months ended March 31, 1999, a decrease of $0.1 million
from $2.6 million for the corresponding three months in 1998. Other operating
expense, net is comprised of (income) loss from joint ventures, amortization of
goodwill, and other intangibles and miscellaneous items. Increases in goodwill
amortization were generally offset by decreases in miscellaneous expenses and a
slight reduction in losses from joint ventures.

     Income from operations. Income from operations was $19.8 million for the
three months ended March 31, 1999 compared to $18.0 million for the three months
ended March 31, 1998. Income from

                                       18
<PAGE>   19

operations represented 4.0% and 4.7% of net sales for the three months ended
March 31, 1999 and 1998, respectively.

     Domestic income from operations was $21.8 million during the three months
ended March 31, 1999, an increase of 16.0% from $18.8 million during the
corresponding period in 1998. International income (loss) from operations was
$(2.0) million during the 1999 period and $(0.8) million during the 1998 period.

     Interest expense, net. Interest expense, net for the three months ended
March 31, 1999 increased to $6.6 million from $2.6 million for the same period
in 1998. Of the $4.0 million increase in interest expense, $1.7 million was due
to the incurrence of $75 million in additional long-term borrowings in April
1998 and $2.3 million was due to increased usage of our credit lines. Short-term
borrowing increased in the first quarter of 1999 as a result of acquisitions,
payments related to the Pulse inspection program and increased working capital
for seasonal needs.

     Other. Other expense (income) was $(0.2) million for the three months ended
March 31, 1999 and $0.2 million for the three months ended March 31, 1998. Other
expense is primarily comprised of currency exchange gains or losses. The
majority of the improvement in other expense (income) was due to the
strengthening of the Canadian dollar.

     Minority interest. Minority interest in subsidiaries' net losses of $(0.5)
million for both the three months ended March 31, 1999 and 1998 represents the
minority interest in Ets. Brancher and, for 1999, McQuay do Brasil.

     Provision for income taxes. The provision for income taxes was $7.3 million
for both the three months ended March 31, 1999 and 1998. The effective tax rate
of 52.5% and 46.9% for the three months ended March 31, 1999 and 1998,
respectively, differs from the statutory federal rate of 35.0% principally due
to state and local taxes and valuation reserves provided for foreign operating
losses. No tax benefits are being recognized for our tax loss carryforwards in
Europe, which will not be used until our operations in Europe are profitable.

     Net income. Net income was $6.6 million and $8.3 million for the three
months ended March 31, 1999 and 1998, respectively. Net income represented 1.4%
and 2.2% of net sales for the three months ended March 31, 1999 and 1998,
respectively.

     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.

     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 of $68.6
million of sales beginning in the third quarter of 1998 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 U.S. 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 McQuay 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
                                       19
<PAGE>   20

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 McQuay do Brasil and Lovelock Luke.

     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 $461.1 million for 1998, an increase of $134.8
million, or 41.3%, from $326.3 million for 1997. Selling, general and
administrative expenses represented 25.3% and 22.6% 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 $413.9
million for 1998, an increase of $99.8 million, or 31.8%, from $314.1 million
for 1997, representing 25.4% and 22.4% 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 $397.2 million for 1998, an increase of
$83.1 million, or 26.5%, from $314.1 million for 1997, representing 24.4% and
22.4% 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 our global operation.

     Other operating expense, net. Other operating expense, net totaled $8.5
million for 1998, an increase of $1.1 million from $7.4 million for 1997. Other
operating expense, net is comprised of (income) loss from joint ventures,
amortization of goodwill and other intangibles and miscellaneous items. The $1.1
million increase is due to increases in amortization of goodwill of $1.7 million
and losses from joint ventures of $1.3 million, partially offset by a decrease
in other intangible and miscellaneous expense of $2.0 million.

     Product inspection charge. In the fourth quarter of 1997, we 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
our Pulse furnace. As part of our normal warranty process, we continuously
monitor the replacement rate for, among other components, heat exchangers in our
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, we publicly announced the Pulse inspection program in
1997. Under the program, we have offered the owners of all Pulse furnaces
installed between 1982 and 1990 a subsidized inspection and a free carbon
monoxide detector. The inspection includes a severe pressure test to determine
the serviceability of the

                                       20
<PAGE>   21

heat exchanger. If the heat exchanger does not pass the test, we will either
replace the heat exchanger or offer a new furnace and subsidize the labor costs
for installation. The cost required for the program depends on the number of
units we find, the number of units that fail the pressure test, whether
consumers select to replace the heat exchanger or receive a new furnace and the
cost of the replacement products. Based on the results of our historical
experience, input from our dealers and consultation with the Consumer Products
Safety Commission, we estimated we could ultimately locate approximately 67% of
the Pulse furnaces that were manufactured between 1982 and 1988. In terms of
estimated failure rates, we utilized the data gathered from "field experience"
tests, which indicated a failure rate of approximately 30%. In terms of consumer
selection, we estimated that half would elect the new heat exchanger and half
would elect the new furnace. Finally, we utilized our 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. We
believe we had adequate information to develop reasonable assumptions in
estimating the cost of the Pulse inspection program.

     We periodically review the reserve balance and at this time believe the
remaining reserve of $13.6 million at March 31, 1999 will be adequate to cover
the remaining costs associated with this inspection program. This program ends
on June 30, 1999.

     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.

     Domestic income from operations was $108.7 million during 1998 as compared
to a loss of $(38.8) million during 1997. International income (loss) from
operations was $(2.1) million during 1998 and $3.6 million for 1997.

     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, $1.3 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, McQuay 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.

     YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

     Net sales. Net sales increased $79.9 million, or 5.9%, to $1,444.4 million
for the year ended December 31, 1997 from $1,364.5 million for the year ended
December 31, 1996. If the effect of the consolidation of Ets. Brancher is
excluded, net sales would have increased by $39.7 million, or 2.9%, to $1,404.2
million for 1997 compared to 1996.

     Net sales related to the North American residential segment were $865.1
million during 1997, an increase of 0.9% from $857.1 million for 1996. This
increase was principally due to increases in the number of heating and air
conditioning units sold by us, despite the fact that industry shipments were
generally down 5%
                                       21
<PAGE>   22

for 1997. The weather in 1997 was mild with a cool spring and modest winter over
most of the U.S., and inventory levels for both dealers and distributors were
higher than normal at the end of 1996. Commercial air conditioning revenues
increased $49.9 million, or 21.8%, to $278.8 million for 1997 compared to 1996.
Of the $49.9 million increase, 61.5% was due to increased volumes of rooftop air
conditioner sales in North America and the balance was due to the consolidation
of Ets. Brancher in the fourth quarter of 1997. Rooftop air conditioner business
increased in 1997 principally due to focused sales efforts through commercial
districts that we established early in 1997 as well as the continued roll out of
the L Series rooftop product line. Net sales related to the commercial
refrigeration segment were $154.3 million during 1997, an increase of 13.8% from
$135.6 million for 1996. This increase was primarily due to the consolidation of
Ets. Brancher in the fourth quarter of 1997. Heat transfer revenues increased
$3.3 million, or 2.3%, to $146.2 million for 1997 compared to 1996. Ets.
Brancher contributed $3.3 million to heat transfer product sales in 1997.

     Domestic sales increased $22.4 million, or 1.8%, to $1,274.9 million for
1997 from $1,252.5 million for 1996 primarily due to the factors discussed
above. International sales increased $57.5 million, or 51.3%, to $169.5 million
for 1997 from $112.0 million for 1996. This increase is primarily due to the
consolidation of Ets. Brancher in the last quarter of 1997.

     Gross profit. Gross profit was $438.5 million for the year ended December
31, 1997 as compared to $402.9 million for the year ended December 31, 1996, an
increase of $35.6 million. Gross profit margins were 30.4% and 29.5% for 1997
and 1996, respectively. The increase of $35.6 million in gross profit was
primarily attributable to increased sales in 1997 and the effect of the
consolidation of Ets. Brancher. Ets. Brancher contributed $11.2 million to gross
profit in 1997, and its gross profit margin was 27.9%. If the effect of the
consolidation of Ets. Brancher is excluded, gross profit margin would have
remained the same for 1997.

     Selling, general and administrative expenses. Selling, general and
administrative expenses were $326.3 million for 1997, an increase of $28.3
million, or 9.5%, from $298.0 million for 1996. Selling, general and
administrative expenses represented 22.6% and 21.8% of net sales for 1997 and
1996, respectively. Of the $28.3 million increase, $12.2 million was related to
the consolidation of Ets. Brancher. Excluding the effect of the consolidation of
Ets. Brancher, selling, general and administrative expenses would have
represented 22.4% of net sales in 1997. The remaining $16.1 million increase in
selling, general and administrative expenses related to expenses in establishing
specialized commercial sales districts in North America, increased expenses
related to a profit sharing plan and other variable cost increases associated
with increased sales.

     Other operating expense, net. Other operating expense, net totaled $7.4
million for 1997, an increase of $3.2 million from $4.2 million for 1996. In
1996, we recognized a non-recurring $4.6 million gain on the sale of a portion
of our interest in Alliance Compressors, a joint venture to manufacture
compressors. After the sale, we owned a 24.5% interest in Alliance Compressors.

     Income (loss) from operations. Income (loss) from operations was $(35.2)
million in 1997, a decrease of $135.8 million from $100.6 million in 1996. The
$135.8 million decrease was primarily due to the $140.0 million non-recurring
pre-tax charge relating to the Pulse inspection program. Excluding the special
charge for the Pulse inspection program and the consolidation of Ets. Brancher,
income from operations would have been $106.1 million in 1997, representing 7.6%
of net sales, the same percent as in 1996.

     Domestic income (loss) from operations was $(38.8) million during 1997 as
compared to $98.0 million during 1996. International income from operations was
$3.6 million during 1997 and $2.6 million for 1996.

     Interest expense, net. Interest expense, net for 1997 decreased to $8.5
million from $13.4 million for 1996. The decrease of $4.9 million in interest
expense was primarily due to higher average cash balances resulting from
improved working capital management. We did not have any short-term borrowings
in 1996 or 1997 and long-term debt remained fairly consistent each year.

     Other. Other expense was $2.0 million for 1997 and $(0.9) million for 1996.
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 represents the minority interest in Ets. Brancher.

                                       22
<PAGE>   23

     Provision (benefit) for income taxes. The effective tax rates for the 1997
benefit and the 1996 provision were 25.5% and 37.9%, 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). There was a net loss of $(33.6) million for the year
ended December 31, 1997 compared to net income of $54.7 million for the year
ended December 31, 1996. If the non-recurring charge relating to the Pulse
inspection program and the consolidation of Ets. Brancher are excluded, net
income would have been $55.2 million for 1997, representing 3.9% of net sales,
compared to 4.0% of net sales for 1996.

LIQUIDITY AND CAPITAL RESOURCES

     We have historically financed our operations and capital requirements from
internally generated funds and, to a lesser extent, borrowings from external
sources. Our capital requirements have related principally to acquisitions, the
expansion of our production capacity and increased working capital needs that
have accompanied sales growth.

     Net cash provided by operating activities totaled $158.8 million, $58.5
million and $5.0 million for 1996, 1997 and 1998, respectively. The reduction in
cash provided by operating activities is primarily due to the Pulse inspection
program as we spent $26.6 million and $86.1 million on this program in 1997 and
1998, respectively. In addition, we had unusually strong sales of our "Lennox"
brand of North American air conditioning products late in 1997 and accordingly
accounts receivable in December 1997 were higher than normal. Net cash provided
by (used in) operating activities was $(57.2) million for the three months ended
March 31, 1999 compared to $(31.7) million for the three months ended March 31,
1998. The increase in cash used in operating activities is primarily due to
increases in accounts and notes receivable resulting from higher first quarter
1999 sales. Net cash used in investing activities totaled $37.1 million, $44.6
million, $212.4 million, $13.7 million and $71.2 million for 1996, 1997 and 1998
and the three months ended March 31, 1998 and 1999, respectively. The greater
use of cash for investing relates primarily to increased acquisition activity as
we spent $14.3 million, $160.5 million, $1.4 million and $51.1 million for
acquisitions in 1997 and 1998 and the three months ended March 31, 1998 and
1999, respectively. Net cash provided by (used in) financing activities was
($44.0) million, ($17.3) million, $89.5 million, $69.2 million and $130.9
million for 1996, 1997 and 1998 and the three months ended March 31, 1998 and
1999, respectively. In 1998, we issued $75.0 million principal amount of notes
and increased short term borrowings by $36.7 million. In the first quarter of
1999, we increased short-term borrowings by $134.5 million primarily to fund
acquisitions. Due to the seasonality of the air conditioning and refrigeration
businesses, we typically use cash in the first six months and generate cash
during the latter half of the year. Accordingly, we do not believe it is
appropriate to compare interim periods to the full fiscal year. Our internally
generated cash flow, along with borrowings under our revolving credit facility,
have been sufficient to cover our working capital, capital expenditure and debt
service requirements over the last three years.

     In the past, we have used a combination of internally generated funds,
external borrowings and our stock to make acquisitions. We intend to acquire
additional heating and air conditioning dealers in the U.S. and Canada. We plan
to finance these acquisitions with a combination of cash, including a portion of
the net proceeds of this offering, stock and debt. As of May 31, 1999, we had
acquired 43 dealers in Canada for an aggregate purchase price of approximately
$62 million and had signed letters of intent to acquire 14 additional Canadian
dealers and eight U.S. dealers for an aggregate purchase price of approximately
$47 million.

     We have agreed to purchase on March 31, 2000 the remaining 30% interest in
Ets. Brancher not owned by us for approximately $17 million. In June 1999, we
acquired James N. Kirby Pty. Ltd. for approximately $67 million. In addition, we
assumed approximately $28 million of Kirby's debt. The purchase price consisted
of approximately $17 million in cash, $36 million in deferred payments and
          shares of common stock. The $36 million in deferred payments will be
made in installments of approximately $12 million per year over the next three
years. If our common stock does not trade at a price greater than $     per
share for five consecutive days from the period from June 1999 to June 2000,
then we are obligated to pay the former owners of Kirby the difference between
the trading price for the last five days of this period and $          for
          of the shares of common stock.

                                       23

     Our capital expenditures were $31.9 million, $34.6 million, $52.4 million
and $20.0 million for 1996, 1997 and 1998 and the three months ended March 31,
1999, respectively. We have budgeted $80 million for capital expenditures for
1999. These expenditures primarily relate to production equipment (including
tooling), training facilities, leasehold improvements and information systems.
The majority of these planned capital expenditures are discretionary. We plan to
finance these capital expenditures using cash flow from operations and available
borrowings under our revolving credit facility.

     At March 31, 1999, we had long-term debt obligations outstanding of $260.2
million. The total long-term debt consists primarily of six issues of notes with
an aggregate principal amount of $240.6 million, interest rates ranging from
6.56% to 9.69% and maturities ranging from 2001 to 2008. The notes contain
restrictive covenants, including covenants that place limitations on our ability
to incur additional indebtedness, encumber our assets, sell our assets or pay
dividends. Our ability to incur debt is limited to 60.0% of our consolidated
capitalization. As of March 31, 1999, our consolidated indebtedness as a percent
of consolidated capitalization was 51.8%. Generally, the aggregate sale of
assets outside the ordinary course of business cannot exceed 15% of our
consolidated assets during any fiscal year and all transfers after January 1,
1998 cannot exceed 30% of our consolidated assets. In addition, in order to pay
dividends or make a sale of assets outside the ordinary course of business, we
must be able to incur $1.00 of additional indebtedness. In addition, we are
required to maintain a consolidated net worth equal to $261.0 million plus 15%
of our consolidated quarterly net income beginning April 1, 1998. At March 31,
1999, the required consolidated net worth was $270.2 million and we had a
consolidated net worth of $374.3 million. Upon a change of control, we 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. Our debt service
requirements (including principal and interest payments) for long-term debt are
$38.1 million for 1999. As of December 31, 1998, we had approximate minimum
commitments on all non-cancelable operating leases of $22 million and $19
million in 1999 and 2000, respectively.

     We have $135 million of borrowings available under our revolving credit
facility. Our revolving credit facility provides for both "standby loans" and
"offered rate loans." Standby loans are made ratably by all lenders under the
revolving credit facility, while offered rate loans are, subject to the terms
and conditions of the credit facility, separately negotiated between us and one
or more members of the lending syndicate. Standby loans bear interest, at our
option, at a rate equal to either (a) the London Interbank Offered Rate plus a
margin equal to 0.150% to 0.405% depending on the ratio of our debt to total
capitalization, or (b) the greater of (1) the Federal Funds Effective Rate plus
0.5%, and (2) the Prime Rate. Offered rate loans bear interest at a fixed rate
agreed to by us and the lender or lenders making such loans. Under the revolving
credit facility, we are obligated to pay fees, including (a) a quarterly
facility fee to each lender under the credit facility equal to a percentage,
varying from 0.100% to 0.220% (depending on the ratio of our debt to total
capitalization) of each lender's total commitment, whether used or unused, under
the revolving credit facility and (b) administrative fees to the administrative
agent and documentation agent under the revolving credit facility. The revolving
credit facility contains the same restrictive covenants and maintenance tests as
the notes. The revolving credit facility will expire on July 13, 2001, unless
earlier terminated according to its terms and conditions.

     In March 1999, we entered into a term credit agreement which provides for
borrowings of up to $115 million. Repayments of borrowings result in a permanent
reduction of the commitment. Loans bear interest, at our option, at a rate equal
to (a) the rate offered by the administrative agent in its London offices plus
1.00% to 1.75%, depending upon the period, or (b) the greater of (1) the Federal
Funds Effective Rate plus 0.5% or (2) the Prime Rate, in each case plus 0% to
0.75%, depending upon the period. Under the term credit agreement, we are
obligated to pay fees, including (a) a quarterly commitment fee equal to 0.15%
of the unused portion of the commitment and (b) administrative fees to the
administrative agent. We are required to use the net proceeds from any issuance
of our securities, including the net proceeds from our initial public offering,
to repay any amounts outstanding under the term credit agreement. The term
credit agreement expires upon completion of this offering. The term credit
agreement otherwise expires on December 31, 1999.

     We believe that cash flow from operations, as well as the net proceeds from
our initial public offering and available borrowings under our revolving credit
facility, will be sufficient to fund our operations for the foreseeable future.
We may pursue additional debt or equity financing in connection with
acquisitions.

QUARTERLY RESULTS OF OPERATIONS

     The following table presents certain of our quarterly information for the
years ended December 31, 1997 and 1998 and the three months ended March 31,
1999. Such information is derived from our unaudited financial statements and,
in the opinion of our management, includes all adjustments, consisting of only
normal recurring adjustments, necessary for a fair presentation of such
information. Operating results for any given quarter are not necessarily
indicative of results for any future period and should not be relied upon as an
indicator of future performance. Beginning with the fourth quarter of 1997, our
results of operations reflect the consolidation of Ets. Brancher.

</TABLE>

     Our quarterly operating results have varied significantly and are likely to
vary significantly in the future. Demand for our products is seasonal and
dependent on the weather. In addition, a majority of our revenue is derived from
products whose sales peak in the summer months. Consequently, we often
experience lower sales levels in the first and fourth quarters of each year.
Because a high percentage of our overhead and operating expenses are relatively
fixed throughout the year, operating earnings and net earnings tend to be lower
in quarters with lower sales.

MARKET RISK

     The estimated fair values of our financial instruments approximate their
respective carrying amounts at March 31, 1999, except as follows (in thousands):

     The fair values presented above are based on the amount of future cash
flows associated with each instrument, discounted using our current borrowing
rate for similar debt instruments of comparable maturity.

The fair values are estimates as of March 31, 1999, and are not necessarily
indicative of amounts for which we could settle currently or indicative of the
intent or ability of us to dispose of or liquidate such instruments.

     Our results of operations can be affected by changes in exchange rates. Net
sales and expenses in currencies other than the U.S. dollar are translated into
U.S. dollars for financial reporting purposes based on the average exchange rate
for the period. During 1996, 1997 and 1998, net sales from outside the U.S. and
Canada represented 8.2%, 11.7% and 19.2%, respectively, of total net sales.
Historically, foreign currency transaction gains (losses) have not had a
material effect on our operations.

     We have entered into foreign currency exchange contracts to hedge our
investment in Ets. Brancher. We do not engage in currency speculation. These
contracts do not subject us 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 Ets. Brancher. As of March 31, 1999, we had
entered into foreign currency exchange contracts with a nominal value of 165.5
million French francs (approximately $27.0 million). These contracts require us
to exchange French francs for U.S. 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, we could be at risk for any currency related fluctuations.

     From time to time we enter into foreign currency exchange contracts to
hedge receivables from our foreign subsidiaries. These contracts do not subject
us to risk from exchange rate movements because the gains or losses on the
contracts offset losses or gains, respectively, on the receivables being hedged.
As of March 31, 1999, we had obligations to deliver the equivalent of $61.7
million of various foreign currencies by June 30, 1999, for which the
counterparties to the contracts will pay fixed contract amounts.

     We have contracts with various suppliers to purchase copper and aluminum
for use in our manufacturing processes. As of March 31, 1999, we had contracts
to purchase 17.1 million pounds of copper over the next 24 months at fixed
prices that average $0.75 per pound ($12.8 million) and contracts to purchase
six million pounds of copper at a variable price equal to the COMEX copper price
(0.63 per pound at March 31, 1999) over the next 12 months. We also had
contracts to purchase 19.3 million pounds of aluminum at $0.61 per pound ($11.8
million) over the next 12 months. The fair value of the copper and aluminum
purchase commitments was a liability of $2.6 million at March 31, 1999.

INFLATION

     Historically, inflation has not had a material effect on our 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.
We have a variety of computer software program applications, computer hardware
equipment and other equipment with embedded electronic circuits, including
applications used in our financial business systems, manufacturing processes and
administrative functions, which are collectively referred to as the "systems".
We expect that our systems will be ready for the Year 2000 transition.

     In order to identify and resolve Year 2000 issues affecting us, we
established a Year 2000 compliance program. The Year 2000 compliance program is
administered by a task force, consisting of members of senior management as well
as personnel from our accounting, internal audit and legal departments, which
has oversight of the information systems managers and other administrative
personnel charged with implementing our Year 2000 compliance program. The task
force has established a specific compliance team for Lennox Corporate and for
each of our operating locations.

     In 1994 we began the replacement of all core business systems for our
domestic subsidiaries. The purpose of this replacement was to upgrade systems
architecture and functionality, improve business integration and implement
process improvements. SAP was selected as the enterprise resource for planning
("ERP") system to replace mission critical software and hardware for Lennox
Industries, Heatcraft's Heat Transfer and Refrigeration Products Divisions and
the Lennox Corporate operations. Fourth Shift was selected as the ERP
                                       26
<PAGE>   27

system for the Electrical Products Division of Heatcraft and is also being
implemented for various subsidiaries of Lennox Global. A new version of ROI
Manage 2000 was implemented for Armstrong. As of December 31, 1998, all
replacements were complete except for the Heat Transfer Division of Heatcraft,
which is scheduled to be complete by September 30, 1999, and upgrades for some
subsidiaries of Lennox Global.

     SAP, Fourth Shift and ROI Manage 2000 have certified that these systems are
Year 2000 compliant. Hardware, operating systems and databases installed to
support these systems are either compliant or have Year 2000 vendor supplied
updates to be applied in 1999. Other smaller applications integrated with SAP
have been replaced or upgraded with Year 2000 compliant software.

     The implementations of SAP, Fourth Shift and ROI Manage 2000 and the
related hardware, operating systems and databases comprise the systems that are
most critical to our operations, which are referred to as "critical systems,"
and address the areas of our business which would have otherwise been
significantly affected by the Year 2000. As of April 30, 1999, we were
approximately 85% complete with the implementation of the Year 2000 compliance
program for all critical systems, and we expect to be 100% complete by September
30, 1999.

     Our Year 2000 Program also addresses compliance in areas in addition to
critical systems, including: voice and data networks, desktop computers,
peripherals, EDI, contracted or purchased departmental software, computer
controlled production equipment, test stations, building security, transport and
heating and air conditioning systems, service providers, key customers and
suppliers and Lennox manufactured and purchased products. As of April 30, 1999,
we were more than 60% complete with the implementation of the Year 2000
compliance program for all such areas, and we expect to be 100% complete by
September 30, 1999.

     We have initiated communications with significant suppliers, customers and
other third parties to identify and assess Year 2000 risks and by September 1999
expect to have developed solutions that will minimize the impact on us. Lennox
Industries distributed surveys to approximately 200 of its major suppliers in
January 1999 and over half of these suppliers have responded. All of these
respondents stated that they are either compliant or are planning to be
compliant. In April 1999, a follow-up survey was sent to the suppliers who had
not yet responded. We expect to resolve any identified problems with critical or
non-responding suppliers or to develop contingency plans where needed. We depend
on third-party trucking companies to deliver finished products from our
factories to our customers. None of Lennox Industries' trucking contractors is
individually critical to our business. About 125 different trucking companies
handle 95% of Lennox Industries' distribution. We have communicated with
approximately 50 of the largest trucking contractors and received assurances
that they will not have service disruptions due to the Year 2000. Our
manufacturing facilities are highly dependent on public utilities, especially
electrical power, natural gas, water and communications companies. If third
party providers, due to the Year 2000 issue, fail to provide us with components
or materials which are necessary to manufacture our products, with sufficient
electrical power and other utilities to sustain our manufacturing process, or
with adequate and reliable means of transporting our products to our customers,
and we have not developed adequate contingency plans, then there could be an
adverse effect on our results of operations at any facility affected by these
problems. Currently, we are not aware of any of our significant third party
providers or customers that are not or will not be Year 2000 compliant.

     We believe that our most reasonably likely worst case scenario is some
short-term, localized disruptions of systems, transportation or suppliers that
will affect an individual business operation, rather than broad-based and
long-term problems that affect operating segments or our operations as a whole.
For the most part, our manufacturing processes are not affected by Year 2000
issues. The most significant uncertainties relate to critical suppliers,
particularly electrical power, water, natural gas and communications companies,
and suppliers of parts that are vital to the continuity of our operations. Where
possible, contingency plans are being formulated and put into place for all
critical suppliers. These plans include developing the necessary safety stock
levels for single source items. These contingency plans should be completed by
October 1999.

     Our estimated cost to become Year 2000 compliant is approximately $7.5
million, of which we have already spent approximately $3.4 million. All of these
expenses will reduce our net income. Of the $7.5 million in total costs,
approximately $5.1 million relates to application software, including consulting
and training relating to the software, of which approximately $2.8 million has
been spent to date. The remaining
                                       27
<PAGE>   28

$2.3 million in total estimated costs relates to infrastructure and hardware, of
which approximately $0.7 million has been spent and the remaining $1.6 million
is expected to be expensed over a three-year period. The costs of application
and infrastructure changes made for reasons other than the Year 2000 and which
were not accelerated are not included in these estimates. We have not deferred
any significant information technology projects because of our response to Year
2000 issues. All Year 2000 costs are being funded from our operating cash flows.
These costs are generally not incremental to existing information technology
budgets.

     The total costs, anticipated impact and the expected dates to complete the
various phases of the project are based on our best estimates using assumptions
about future events. However, no assurance can be given that actual results will
be consistent with such estimates and, therefore, actual costs, completion dates
and impact may differ materially from the plans. See "Special Note Regarding
Forward-Looking Statements."

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 is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. We do not believe that the adoption of this
pronouncement will have a significant impact on our financial statements.

                                    BUSINESS

     We are a leading global provider of climate control solutions. We design,
manufacture and market a broad range of products for the HVACR markets. Our
products are sold under well-established brand names including "Lennox",
"Armstrong Air", "Bohn", "Larkin", "Heatcraft" and others. We are also one of
the largest manufacturers in North America of heat transfer products, such as
evaporator coils and condenser coils. We have leveraged our 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 our product innovation
and the quality and reliability of our products. As a result of recent
acquisitions, we have also become a leader in the growing market for hearth
products, which includes pre-fabricated fireplaces and related products.
Historically, we have sold our "Lennox" brand of residential heating and air
conditioning products directly to a network of installing dealers, which
currently numbers approximately 6,000, making us the largest wholesale
distributor of these products in North America. We have recently initiated a
program to acquire dealers in metropolitan areas in the U.S. and Canada so that
we can provide heating and air conditioning products and services directly to
consumers.

     Our furnaces, heat pumps, air conditioners, pre-fabricated fireplaces and
related products are available in a variety of designs, efficiency levels and
price points that provide an extensive line of comfort systems. A majority of
our sales of residential heating and air conditioning products in the U.S. and
Canada are to the repair and replacement market, which is less cyclical than the
new construction market. We also provide a range of air conditioning products
for commercial market applications such as mid-size office buildings,
restaurants, churches and schools. Our commercial refrigeration products are
used primarily in cold storage applications for food preservation in
supermarkets, convenience stores, restaurants, warehouses and distribution
centers. Our heat transfer products are used by us in our HVACR products and
sold to third parties.

     Shown below are our four business segments, the key products and brand
names within each segment and 1998 net sales by segment. The North American
residential segment also includes installation, maintenance and repair services
performed by Lennox-owned dealers. See our audited financial statements included
elsewhere in this prospectus for more information on our segments.

</TABLE>

     We market and distribute our products using multiple brand names through
multiple distribution channels to penetrate different segments of the HVACR
market. Our "Lennox" brand of residential heating and air conditioning products
is sold directly through installing dealers -- the "one-step" distribution
system -- which has created strong and long-term relationships with dealers in
North America. Our "Armstrong Air," "Air-Ease," "Concord" and "Magic-Pak"
residential heating and air conditioning brands are sold to regional
distributors that in turn sell the products to installing contractors -- the
"two-step" distribution system typically utilized in the heating and air
conditioning industry. The acquisition of heating

                                       29
<PAGE>   30

and air conditioning dealers in Canada and the planned acquisition of dealers in
the U.S. allows us to participate in the retail sale and service of heating and
air conditioning products. Our hearth products, commercial air conditioning
products and refrigeration products are also sold under multiple brand names and
through a combination of wholesalers, contractors, original equipment
manufacturers, manufacturers' representatives and national accounts.

     From our beginning in 1895 until the mid-1980's, we focused primarily on
the North American residential heating and air conditioning market. In the
1980's, we expanded our product offerings by acquiring several heat transfer and
commercial refrigeration businesses. In the mid-1990's, we increased our
international presence, product offerings and brand portfolio through
acquisitions in Europe, Latin America and the Asia Pacific region. The most
significant international acquisition was the purchase in 1996 of a 50% interest
in two operating subsidiaries of Ets. Brancher for approximately $22.0 million,
which significantly expanded our geographic presence and provided us with an
entry into the commercial air conditioning and refrigeration markets in Europe.
In 1997, we increased our ownership interest in Ets. Brancher to 70% for an
additional $18.4 million. In September 1998, we acquired a majority interest in
McQuay do Brasil S.A., a Brazilian company which participates in the commercial
refrigeration and heat transfer markets in Brazil and surrounding countries, for
$20.5 million. We recently expanded our product offerings to include hearth
products through the acquisitions of 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. As a result of these acquisitions,
we are one of the largest manufacturers of hearth products in the U.S. and
Canada, offering a broad line of products through a variety of distribution
channels. In the fourth quarter of 1998, we acquired the assets of Lovelock Luke
Pty. Limited, a distributor of refrigeration and related equipment in Australia
and New Zealand, for approximately $7 million. In May 1999, we acquired
Livernois Engineering Holding Company and related patents for approximately $21
million. Livernois produces heat transfer manufacturing equipment for the HVACR
and automotive industries. We 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 $67 million.

     We were 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 Lennox was distributed to
all generations of his family. Today, Lennox's ownership is broadly distributed
among approximately 110 descendants of or persons otherwise related to D.W.
Norris.

INDUSTRY OVERVIEW

     NORTH AMERICAN RESIDENTIAL

     Residential Heating and Air Conditioning. The residential market in the
U.S. and Canada is divided into two basic categories: furnaces and air
conditioning systems. Air conditioning is further divided into two basic
categories: residential split systems and heat pumps and window and room air
conditioners. We do not participate in the window and room air conditioner
category. Split system air conditioners are comprised of a condensing unit,
normally located outside of the household, and an evaporator unit, which is
typically positioned indoors to use the blower mechanism of a furnace or fan
coil unit in the case of a heat pump.

     In recent decades the functions performed by the products of this market
have become increasingly important to modern life. The advent of modern, high
efficiency air conditioning was one of the significant factors contributing to
the growth of large metropolitan areas in parts of the southern U.S. According
to a report published by the U.S. Department of Housing and Urban Development
for 1995, 98% of all new houses constructed in the southern region of the U.S.
and 80% of all new houses in the U.S. included central air conditioning.
According to the U.S. Census Bureau, manufacturers' sales for all residential
air conditioners and warm air furnaces produced in 1997 for the U.S. market were
approximately $5.5 billion, reflecting a

                                       30
<PAGE>   31

compound annual growth rate of approximately 7.2% from 1993 to 1997. We estimate
that manufacturers' sales in Canada were approximately $200 million in 1997.

     Services in the residential market in North America consist of the
installation, replacement, maintenance and repair of heating and air
conditioning systems at existing residences and the installation of heating and
air conditioning systems at newly constructed homes. This market is served by
small, owner-operated businesses operating in a single geographic area and
dealers owned by consolidators, utility companies and others, some of whom may
operate under a uniform trade name and in multiple geographic locations. The
retail sales and service market in the U.S. is comprised of over 30,000 dealers.

     The principal factors affecting market growth in the North American
residential market are new home construction, the weather and economic
conditions, especially consumer confidence. Residential heating and air
conditioning products are sold for both the replacement and new construction
markets. The residential new construction market has historically been a more
price sensitive market because many homebuilders focus on initial price rather
than operating efficiency or ongoing service costs.

     Hearth Products. The main components of the hearth products market are
pre-fabricated gas fireplaces and inserts, pre-fabricated wood burning
fireplaces and inserts, pellet stoves, gas logs, and accessories and
miscellaneous items. We participate in all major aspects of the hearth products
market. According to the Hearth Products Association, an industry trade group,
there were 2.3 million unit sales in 1998, including all gas and wood burning
appliances, and this market is expected to grow at 7.5% per year through 2000.
The addition of a fireplace is considered one of the best return on investment
decisions that a homeowner can make. Hearth products are distributed and sold
through many channels, ranging from contractors to specialty retailers.

     COMMERCIAL AIR CONDITIONING

     The global commercial air conditioning market is divided into two basic
categories: unitary air conditioners and applied systems. We primarily
participate in the unitary air conditioning market in North America and in both
the unitary and applied systems markets in Europe. Unitary products consist of
modular split systems and packaged products with up to 30 tons of cooling
capacity. One ton of cooling capacity is equivalent to 12,000 BTUs and is
generally adequate to air condition approximately 500 square feet of space.
Packaged units are self-contained heating and cooling or cooling only units that
typically fit on top of a low rise commercial building such as a shopping center
or a restaurant. Applied systems are typically larger engineered systems, which
are designed to operate in multi-story buildings and include air cooled and
water cooled chillers, air handling units and equipment to monitor and control
the entire system.

     According to the Air-Conditioning & Refrigeration Institute, an industry
trade group, global manufacturers' sales for all commercial air conditioning
systems produced in 1994 (the latest available data) were approximately $14
billion. The principal factors affecting growth in this market are new
construction, economic conditions and environmental regulation of refrigerants.
Unlike residential heating and air conditioning systems, some commercial air
conditioning systems use refrigerants that have been banned or that are
currently being phased out, especially in Europe. We expect that such regulation
will lead to increased growth in this market.

     COMMERCIAL REFRIGERATION

     The global refrigeration market is a highly diversified market, including
everything from household refrigerators and walk-in coolers to large, ammonia
based flash freezing plants and process cooling equipment. We define our served
market as the design and manufacture of equipment used in cold storage,
primarily for the preservation of perishable goods. Our served market includes
condensing units, unit coolers, air cooled condensers, non-supermarket racks and
packaged systems. According to the U.S. Census Bureau, our served market in the
U.S. accounted for approximately $510.9 million in revenues in 1997, reflecting
a compound annual growth rate of approximately 5.3% from 1993 to 1997.

                                       31
<PAGE>   32

     The principal factors affecting growth in the commercial refrigeration
market are:

     - new commercial construction activity, including construction of
       supermarkets, restaurants, convenience stores and distribution centers;

     - replacement and retrofit activity in commercial buildings such as
       efficiency improvements and store design changes; and

     - emergency replacement activity such as replacement of weather related
       product/component breakdowns and product maintenance.

     HEAT TRANSFER

     The heat transfer surface or coil is a fundamental technology employed in
the heating and cooling cycles for HVACR products. The global heat transfer
surface market is comprised not only of the traditional HVACR applications such
as furnaces, air conditioners and unit coolers, but also numerous other
applications such as ice machines, refrigerated trucks, farm equipment and
off-road vehicles, recreational vehicles, computer room air conditioners and
process cooling equipment used with sophisticated laser cutting machines. We
produce heat transfer surfaces not only for traditional HVACR applications, but
also for many of these other applications. Many HVACR manufacturers produce
standard coils for their own use and generally do not sell coils to third
parties. Coils are also designed and produced by independent coil manufacturers
and sold to original equipment manufacturers for use in their products. Coils
are typically designed, developed and sold by engineers who work with customers
to produce a coil that will meet the customer's precise specifications. Factors
affecting a coil purchaser's decision are quality, delivery time, engineering
and design capability, and price.

     Since heat transfer products are a fundamental part of HVACR products, the
heat transfer market is driven by the same economic factors that affect the
HVACR markets generally. Because of the fragmented nature of this market and the
fact that coils are often produced internally by HVACR manufacturers, it is
difficult to gauge the size of the worldwide served heat transfer market.
According to the U.S. Census Bureau, the served market in the U.S. (i.e., third
party sales) accounted for approximately $528.1 million in revenues in 1997,
reflecting a compound annual growth rate of approximately 6.2% from 1993 to
1997.

COMPETITIVE STRENGTHS

     We have a combination of strengths that position us to continue to be a
leading provider of climate control solutions including:

     STRONG BRAND RECOGNITION AND REPUTATION

     We believe that our well known brand names and reputation for quality
products and services position us to compete successfully in our existing
markets and to continue to expand internationally. Our studies indicate that our
"Lennox" brand is the most widely recognized brand name in the North American
residential heating and air conditioning markets. Furthermore, in a recent
survey of home builders, the "Lennox" brand received the highest overall rating
in terms of product quality for furnaces and unitary air conditioners. We market
our other HVACR and hearth products under the well known brand names of
"Armstrong Air", "Bohn", "Larkin" and "Superior", among others.

     BREADTH OF DISTRIBUTION

     We market and distribute our products using multiple brand names through
multiple distribution channels to penetrate different segments of the HVACR
market. We sell our heating and air conditioning products through independent
and Lennox-owned installing dealers, as well as through regional distributors.
Our hearth products, commercial air conditioning and refrigeration products are
also sold under multiple brand names and through a combination of wholesalers,
installing contractors, manufacturers' representatives, original equipment
manufacturers, national accounts and specialty retailers. We believe that sales
growth is

                                       32
<PAGE>   33

driven, in part, by the level of exposure to our customers and our distribution
strategy is designed to maximize this exposure.

     PROVEN HEAT TRANSFER EXPERTISE

     Heat transfer surfaces, which include evaporator and condenser coils, are
critical to the operation of most HVACR products. For a given application, a
variety of factors must be evaluated, such as the size of the HVACR unit and
desired energy efficiency, while considering such additional elements as
manufacturing ease. Since our acquisition of the Heatcraft business in 1986, we
have devoted significant resources to the development of heat transfer surfaces.
We use computer-aided design and other advanced software to improve the
efficiency of designs and simulate and evaluate the movement of refrigerants
even before a prototype is built. Since we also produce coils for sale to third
parties, we are able to spread our research and development costs over third
party purchases of heat transfer products as well as sales of our own HVACR
products. We acquired Livernois Engineering Holding Company and related patents
in May 1999 which provides us with access to additional heat transfer
technology. Livernois produces heat transfer manufacturing equipment for the
HVACR and automotive industries.

     COMMITMENT TO PRODUCT INNOVATION AND TECHNOLOGICAL LEADERSHIP

     Throughout our history, we have dedicated substantial resources to research
and development and product innovation. We pioneered the introduction of the
forced air furnace in 1935, which resulted in new approaches to home design for
more efficient heating. Other examples of our product innovation include:

     - the multi-zone rooftop air conditioner in 1965;

     - the two-speed condensing unit for more efficient air conditioning in
       1973;

     - the high efficiency gas furnace in 1982;

     - the first commercially available high efficiency combination hot water
       heater and furnace in 1994; and

     - "Floating Tube" and "Thermoflex" technologies, which significantly reduce
       leaks in air cooled condensers and unit coolers, in 1995.

     We have invested approximately $125 million over the last five years on
research and development activities, and we intend to continue to invest in
these activities to create innovative and technologically superior products.

     DEMONSTRATED MANUFACTURING EFFICIENCY

     Over the last several years, we have implemented advanced manufacturing
techniques and created programs to incentivize our employees to reduce
production cycle lead times to a week in many of our manufacturing facilities,
compared to lead times of 90 days or more before the introduction of such
concepts. These programs have not only led to improvements in inventory
turnover, but also reductions in controllable working capital, which we define
as inventories plus trade accounts receivables less accounts payable. From
January 1996 to December 1998, controllable working capital as a percent of
sales has declined from 36.1% to 26.7%, a reduction of 9.4%. If controllable
working capital management had not improved, we estimate that our investment in
working capital would have been approximately $170 million higher at December
31, 1998, which is based on the 9.4% improvement multiplied by 1998 net sales.

GROWTH STRATEGY

     Our growth strategy is designed to capitalize on our competitive strengths
in order to expand our market share and profitability in the worldwide HVACR
markets. We will continue to pursue internal programs and strategic acquisitions
that broaden our product and service offerings, expand our market opportunities
and enhance our technological expertise. We continually review acquisition
candidates but do not have any agreements or commitments with respect to any
significant acquisitions except for the acquisition of North American heating
and air conditioning dealers described below. The key elements of this strategy
include:

     EXPAND MARKET IN NORTH AMERICA

     Our program to acquire heating and air conditioning dealers in the U.S. and
Canada represents a new direction for the heating and air conditioning industry
because, to our knowledge, no other major manufacturer has made a significant
investment in retail distribution. This strategy will enable us to extend our
distribution directly to the consumer, thereby permitting us to participate in
the revenues and margins available at the retail level while strengthening and
protecting our brand equity. We believe 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 U.S. is comprised
of over 30,000 dealers. We started this program in September 1998, and as of May
31, 1999 we had acquired 43 dealers in Canada for an aggregate purchase price of
approximately $62 million and had signed letters of intent to acquire 14
additional Canadian and eight U.S. dealers for an aggregate purchase price of
approximately $47 million. We intend to start acquiring dealers in the U.S. by
initially focusing on our existing "Lennox" dealers and will try to achieve a
balance between residential new construction, residential replacement and light
commercial activities. We believe our long history of direct relationships with
our dealers through the one-step distribution system and the resulting knowledge
of local markets will give us advantages in identifying and acquiring suitable
candidates. We have assembled an experienced management team to administer the
dealer operations, and we have developed a portfolio of training programs,
management procedures and goods and services that we believe will enhance the
quality, effectiveness and profitability of dealer operations.

     In addition to our acquisition program, we have initiated a program to
strengthen our independent dealer network by providing all dealers with a broad
array of services and support. Participants in a newly-created associate dealer
program will receive retirement and other benefits in exchange for agreeing that
at least 75% of their residential heating and air conditioning purchases will be
of our products and for granting us a right of first refusal to acquire their
businesses. As of May 31, 1999, 570 dealers in the U.S. and Canada were
participating in our associate dealer program. All independent dealers,
including participants in the associate dealer program, will be provided with
access to Lennox-sponsored volume purchasing programs with third parties for
goods and services used in their businesses.

     We also intend to increase our market share in North America by:

     - selectively expanding our "Lennox" independent dealer network;

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

     - promoting the cross-selling of our hearth products to our "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 U.S. to the southern and western
       portions of the U.S.;

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

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

     EXPLOIT INTERNATIONAL OPPORTUNITIES

     Worldwide demand for residential and commercial heating, air conditioning,
refrigeration and heat transfer products is increasing. We believe 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, we have
made substantial investments in manufacturing facilities in Europe, Latin
America and Asia Pacific through acquisitions, including a 70% interest in Ets.
Brancher. Our international sales have grown from $112.0 million in 1996 to
$349.5 million in 1998. We will continue to focus on expanding our international
operations through acquisitions and internal growth to take advantage of
international growth opportunities. We are also investing additional resources
in our international operations with the goal of achieving manufacturing and
distribution efficiencies comparable to that of our North American operations.

     INCREASE PRESENCE IN HEARTH PRODUCTS MARKET

     With our recent acquisitions of hearth products companies, we now
manufacture and sell one of the broadest lines of hearth products in North
America. We offer multiple brands of hearth products at a range of price points.
We believe that this broad product line will allow us to compete successfully in
the hearth products market since many distributors prefer to concentrate their
product purchases with a limited number of suppliers. We believe that we can
increase our penetration of this market by selling in the distribution channels
we acquired and through our historical distribution channels. Many of our
heating and air conditioning dealers have begun to expand their product
offerings to include hearth products.

     CONTINUE PRODUCT INNOVATION

     An important part of our growth strategy is to continue to invest in
research and new product development. We have designated a number of our
facilities as "centers for excellence" that are responsible for the research and
development of core competencies vital to our 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 our operating divisions. Historically, our commitment to research and
development has resulted in product innovations such as the first high
efficiency gas furnace. More recently, we were the first to manufacture and
market a complete combination high efficiency water heater and furnace, the
CompleteHeat, and also developed an integrated electronic refrigeration control
system, the Beacon control system.

PRODUCTS

     NORTH AMERICAN RESIDENTIAL PRODUCTS AND SERVICES

     Heating and Air Conditioning Products. We manufacture and market 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. We market these products through
multiple brand names. In addition, we manufacture zoning controls, thermostats
and a complete line of replacement parts. We believe that by maintaining a broad
product line with multiple brand names, we can address different market segments
and penetrate multiple distribution channels.

     Our 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 us with components for our
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. We started this business
in 1993 and have been able to achieve an approximate 20% share of this market
for evaporator coils through the application of our technological and
manufacturing skills.

                                       35
<PAGE>   36

     Hearth Products. We believe we are the only North American HVACR
manufacturer that also designs, manufactures and markets residential hearth
products. Our 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. Prior to
the hearth products acquisitions, we offered a limited selection of hearth
products in Canada and, to a lesser extent, in the U.S. We substantially
expanded our offering of hearth products and distribution outlets with these
acquisitions. We currently market our hearth products under the "Lennox",
"Superior", "Marco", "Whitfield", and "Security Chimneys" brand names. We
believe that our strong relationship with our dealers and our brand names will
assist in selling into this market.

     Retail Service. With our recently initiated program of acquiring dealers in
the U.S. and Canada, we have begun to provide installation, maintenance, repair
and replacement services for heating and air conditioning systems 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. We also sell a wide range of mechanical
and electrical equipment, parts and supplies in connection with these services.

     COMMERCIAL AIR CONDITIONING

     We manufacture and sell commercial air conditioning equipment in North
America, Europe, Asia Pacific and South America.

     North America. In the North American commercial markets, our air
conditioning equipment is used in applications such as low rise office
buildings, restaurants, retail and supermarket centers, churches and schools.
Our 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, we sell unitary
equipment as opposed to larger applied systems. Our newest rooftop unit, the 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. We believe that this product's success is attributable to its
efficiency, design flexibility, low life cycle cost, ease of service and
advanced control technology.

     International. We compete in the commercial air conditioning market in
Europe through our ownership of 70% of Ets. Brancher and Ets. Brancher's
operating subsidiaries, HCF S.A. and Friga-Bohn S.A. We have agreed to buy the
remaining 30% interest in Ets. Brancher on March 31, 2000 for 102.5 million
French francs, or approximately $17 million. HCF manufactures and sells unitary
products which range from two to 30 tons and applied systems which range up to
500 tons. HCF's products consist of chillers, air handlers, fan coils and large
rooftop units and serve medium high-rise buildings, institutional applications
and other field engineered applications. HCF 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 and the
Czech Republic.

     We have been active in Australia for several years, primarily in the
distribution of our residential and light commercial heating and air
conditioning products manufactured in North America. In 1997, we acquired the
assets of Alcair Industries, an Australian manufacturer of commercial heating
and air conditioning products (packaged and split systems) ranging in size from
two to 60 tons. This acquisition provided us with a manufacturing presence,
doubled our revenues in Australia and added marketing, distribution and
management strength to our operations in Australia.

     Through our 50% owned Fairco joint venture in Argentina, we manufacture
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. We are one of the leading manufacturers of commercial
refrigeration products in North America. Our refrigeration products include
chillers, condensing units, unit coolers, fluid coolers, air cooled condensers
and air handlers. Our 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 our sale of commercial refrigeration products, we routinely
provide application engineering for consulting engineers, contractors and
others. Some of our larger commercial refrigeration projects have included the
sale of custom designed systems for the Georgia Dome, Camden Yards, Ohio
University, the Boston Museum of Fine Arts and Ericsson Stadium.

     International. Friga-Bohn manufactures and markets refrigeration products
through manufacturing facilities and joint ventures located in France, Italy and
Spain. Friga-Bohn'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.

     We also own 50% of a joint venture in Mexico that produces unit coolers and
condensing units of the same design and quality as those manufactured by us in
the U.S. Since this venture produces a smaller range of products, the product
line is complemented with imports from the U.S. 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.

     In the third quarter of 1998, we acquired a 79% interest in McQuay do
Brasil S.A., a Brazilian company that manufactures condensing units and unit
coolers. We believe this acquisition gives us the leading market share for
commercial refrigeration products in Brazil.

     In the fourth quarter of 1998, we acquired the assets of Lovelock Luke Pty.
Limited, a distributor of refrigeration and related equipment in Australia and
New Zealand. This acquisition gives us an established commercial refrigeration
business in Australia and New Zealand.

     In June 1999, we acquired James N. Kirby Pty. Ltd. for approximately $67
million. Kirby is an Australian company that manufactures commercial
refrigeration and heat transfer products in Australia and distributes commercial
refrigeration equipment through its and Lovelock Luke'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 our commercial refrigeration and heat
transfer business in the Asia Pacific region.

     HEAT TRANSFER

     We are one of the largest manufacturers of heat transfer coils in the U.S.,
Europe, 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 our original equipment manufacturer coils
are produced for use in our residential and commercial HVACR products. We also
produce private label replacement coils for use in other manufacturers' HVACR
equipment. We believe that the engineering expertise of our sales force provides
us with an advantage in designing and applying these products for our customers.
Advanced computer software enables us 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, we
also produce 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. We are the industry leader in this market and have designed our
manufacturing processes and systems in North America so that we can deliver
custom coils within 48 hours of receipt of an order. This premium service
enables us to receive superior prices and generate attractive margins.

                                       37
<PAGE>   38

     We also design and manufacture the equipment and tooling necessary to
produce coils. We use such equipment and tooling in our manufacturing facilities
and sell 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 we have the ability to quickly produce the equipment and tooling
necessary to manufacture heat transfer products and systems, we can accelerate
the international growth of our heat transfer products segment. For example, we
were able to design, manufacture and deliver the equipment necessary to produce
evaporator and condenser coils for our joint venture in Mexico in what we
estimate was half the time than would otherwise have been required to obtain the
equipment from third parties. Upon completion of our acquisition of Livernois,
we will also supply heat transfer manufacturing equipment to the automotive
industry.

     In addition to manufacturing heat transfer products in the North American
market, we produce coils for the European market through a joint venture in the
Czech Republic. Our joint venture in Mexico produces evaporator and condenser
coils for use in that country and for export to the Caribbean and the U.S. Our
Brazilian joint venture manufactures heat transfer coils that are sold to both
HVACR manufacturers and automotive original equipment manufacturers in Brazil.

MARKETING AND DISTRIBUTION

     We manage numerous distribution channels for our products in order to
better penetrate the HVACR market. Generally, our products are sold through a
combination of distributors, independent and company-owned dealers, wholesalers,
manufacturers' representatives, original equipment manufacturers and national
accounts. We have also established separate distribution networks in each
country in which we conduct operations. We deploy dedicated sales forces across
all our 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, we have 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. We have approximately 1,600 persons employed
in sales and marketing positions and spent $50.2 million on advertising,
promotions and related marketing activities in 1998.

     One example of the competitive strength of our marketing and distribution
strategy is in the North American residential heating and air conditioning
market, in which we use three distinctly different distribution
approaches -- the one-step distribution system, the two-step distribution system
and sales made directly to consumers through Lennox-owned dealers. We market and
distribute our "Lennox" brand of heating and air conditioning products directly
to approximately 6,000 dealers that install these products.

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

     We have initiated a program to acquire high quality dealers in metropolitan
areas in the U.S. and Canada so we can provide heating and air conditioning
products and services directly to consumers. We intend to start acquiring
dealers in the U.S. by initially focusing on our existing "Lennox" dealers who
are part of our one-step distribution system.

     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. We spent an aggregate of $40.1 million in advertising,
promotions and related marketing activities in 1998 on the "Lennox" brand alone.

                                       38
<PAGE>   39

MANUFACTURING

     We operate 15 manufacturing facilities in the U.S. and Canada and 19
outside the U.S. and Canada. These plants range from small manufacturing
facilities to large 1,000,000 square foot facilities in Grenada, Mississippi and
Marshalltown, Iowa. In our facilities most impacted by seasonal demand, we
manufacture both heating and air conditioning products to smooth seasonal
production demands and maintain a relatively stable labor force. We are
generally able to hire temporary employees to meet changes in demand.

     Some of the recently acquired manufacturing facilities have not yet reached
the levels of efficiency that have been achieved at our plants which we have
owned for a longer time. However, we intend to bring our manufacturing and
operating expertise to these plants.

PURCHASING

     We rely on various suppliers to furnish the raw materials and components
used in the manufacture of our products. To maximize our buying power in the
marketplace, we utilize a "purchasing council" that consolidates purchases of
our 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 we believe that
there are alternative suppliers for all of our key raw material and component
needs. Compressors, motors and controls constitute our most significant
component purchases, while steel, copper and aluminum account for the bulk of
our raw material purchases. Although most of the compressors used by us are
purchased directly from major compressor manufacturers, we own a 24.5% interest
in a joint venture to manufacture compressors in the one and one-half to seven
horsepower range. We expect that this joint venture, which began limited
production in April 1998, will be capable of providing us with a substantial
portion of our compressor requirements in the residential air conditioning
market after achieving full production levels, which is expected in 2001.

     We attempt 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 our needs throughout the year. In instances where
we are unable to pass on to our customers increases in the costs of copper and
aluminum, we enter into forward contracts for the purchase of such materials. We
have forward commitments for the substantial majority of our internal needs of
aluminum through December 1999 and copper through December 2000.

INFORMATION SYSTEMS

     Our 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. Our largest operating
divisions began installing the SAP enterprise business software system in 1996.
We have substantially completed the implementation of SAP software and full
implementation by all divisions converting to SAP is expected to be completed by
the end of 1999. The SAP software system is designed to facilitate the flow of
information and business processes across all business functions such as sales,
manufacturing, distribution and financial accounting.

TECHNOLOGY AND RESEARCH AND DEVELOPMENT

     We support an extensive research and development program focusing on the
development of new products and improvements to our existing product lines. We
spent an aggregate of $23.2 million, $25.4 million and $31.8 million on research
and development during 1996, 1997 and 1998, respectively. As of December 31,
1998, we employed approximately 480 persons dedicated to research and
development activities. We have 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 our business, such as combustion technology, vapor
compression, heat transfer and low temperature refrigeration.

                                       39
<PAGE>   40

     We use 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 us the ability to run complex computer simulations
on a product design before a working prototype is created. We operate a full
line of metalworking equipment and advanced laboratories certified by applicable
industry associations.

PATENTS AND PROPRIETARY RIGHTS

     We hold numerous patents that relate to the design and use of our products.
We consider these patents important, but no single patent is material to the
overall conduct of our business. Our policy is to obtain and protect patents
whenever such action would be beneficial to us. No patent which we consider
material will expire in the next five years. We own several trademarks that we
consider important in the marketing of our 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), Air-Ease(R), Concord(R), Magic-Pak(R),
Superior(TM), Marco(R), Whitfield(R), Security Chimneys(R), Janka(TM),
Alcair(TM) and Friga-Bohn(TM). These trademarks have no fixed expiration dates
and we believe our rights in these trademarks are adequately protected.

COMPETITION

     Substantially all of the markets in which we participate are highly
competitive. The most significant competitive factors facing us are product
reliability, product performance, service and price, with the relative
importance of these factors varying among our product lines. In addition, as we
acquire more heating and air conditioning dealers, we will face increasing
competition from independent dealers and dealers owned by consolidators and
utility companies. Our competitors may have greater financial and marketing
resources than we have. Listed below are some of the companies that we view as
our main manufacturing competitors in each segment we serve, with relevant brand
names, when different than the company name, shown in parentheses.

     - North American residential -- United Technologies Corporation (Carrier);
       Goodman Manufacturing Company (Janitrol, Amana); American Standard
       Companies Inc. (Trane); York International Corporation; Hearth
       Technologies Inc. (Heatilator); and CFM Majestic, Inc. (Majestic).

     - Commercial air conditioning -- United Technologies Corporation (Carrier);
       American Standard Companies Inc. (Trane); York International Corporation;
       Daikin Industries, Ltd.; and McQuay International.

     - Commercial refrigeration -- United Technologies Corporation (Ardco
       Group); Tecumseh Products Co.; Copeland Corporation; and Hussmann
       International Inc. (Krack).

     - Heat transfer -- Modine Manufacturing Company and Super Radiator Coils.

EMPLOYEES

     As of December 31, 1998, we employed approximately 11,700 employees,
approximately 3,400 of which were represented by unions. The number of hourly
workers we employ during the course of the year may vary in order to match our
labor needs during periods of fluctuating demand. We believe that our
relationships with our employees are generally good.

     Within the U.S., we have eight manufacturing facilities and five
distribution centers, along with our 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. At our significant manufacturing facilities, one collective
bargaining agreement expires in December 1999 -- Lynwood, California. Three
collective bargaining agreements expire in 2000 -- Marshalltown, Iowa,
Burlington, Washington and Atlanta, Georgia -- and three expire in
2002 -- Bellevue, Ohio, Danville, Illinois and Union City, Tennessee. Following
the expiration of the collective bargaining agreement in April 1999, we
experienced a work stoppage at our Bellevue, Ohio factory for three weeks in May
1999. This facility has a new collective bargaining agreement that expires April
2002. Outside of the U.S., we have 12 significant
                                       40
<PAGE>   41

facilities that are represented by unions. The four agreements for HCF in France
have no fixed expiration date. The agreement at our facility in Laval, Quebec
expires in December 1999 and the agreement at our facility in Burgos, Spain
expires in 2000. The agreement at our facility in Toronto, Ontario expired in
April 1999 and, as has been the case in the past, the employees at this facility
are continuing to work under the expired contract pending negotiation of a new
agreement. We believe that our relationships with the unions representing our
employees are generally good, and do not anticipate any material adverse
consequences resulting from negotiations to renew these agreements.

 * Facilities owned or leased by a joint venture in which we have an interest.

     In addition to the properties described above and excluding dealer
facilities, we lease over 55 facilities in the U.S. for use as sales offices and
district warehouses and a limited number of additional facilities worldwide for
use as sales and service offices and regional warehouses. We believe that our
properties are in good condition and adequate for our requirements. We also
believe that our principal plants are generally adequate to meet our production
needs.

REGULATION

     Our 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 our 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. We believe we
are in substantial compliance with such existing environmental laws and
regulations. Our non-U.S. 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 U.S. We
believe we are in substantial compliance with applicable non-U.S. 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 us and our competitors because
of the common usage of HCFCs as refrigerants for air conditioning and
refrigeration equipment. As discussed below, we do not believe that
implementation of the phase out schedule for HCFCs contained in the current
regulations will have a material adverse effect on our financial position or
results of operations. We do believe, however, that there will likely be
continued pressure by the international environmental community for the U.S. and
other countries to accelerate the phase out schedule. We have been an active
participant in the ongoing international dialogue on these issues and believe
that we are well positioned to react to any changes in the regulatory landscape.

                                       42
<PAGE>   43

     In September 1987, the U.S. 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 us
and our competitors. Under the Act and implementing regulations, all HCFCs must
be phased out between 2010 and 2030. We believe that these regulations as
currently in effect will not have a material adverse effect on our operations.
It is not expected that the planned phase out of HCFCs will have a significant
impact on the sales of products utilizing these refrigerants prior to the end of
the decade. 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 U.S. 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 our future financial
results and the industry generally.

     We, together with major chemical manufacturers, are continually in the
process of reviewing and addressing the potential impact of refrigerant
regulations on our products. We believe 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, we do not foresee any material adverse impact on our
business or competitive position as a result of the Montreal Protocol, the 1990
Clean Air Act amendments or their implementing regulations. However, we believe
that the implementation of severe restrictions on the production, importation or
use of refrigerants we employ in larger quantities or acceleration of the
current phase out schedule could have such an impact on us and our competitors.

     We are 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 our products. We have
developed and are developing products which comply with National Appliance
Energy Conservation Act regulations, and do not believe that such regulations
will have a material adverse effect on our business. The U.S. 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. We believe we are well positioned to comply with any new
standards that may be promulgated by the Department of Energy and do not foresee
any adverse material impact from a National Appliance Energy Conservation Act
standard change.

     Remediation Activity. In addition to affecting our ongoing operations,
applicable environmental laws can impose obligations to remediate hazardous
substances at our properties, at properties formerly owned or operated by us and
at facilities to which we sent or send waste for treatment or disposal. We are
currently involved in remediation activities at our facility in Grenada,
Mississippi and at a formerly owned site in Ft. Worth, Texas. In addition,
former hazardous waste management units at two of our facilities, Danville,
Illinois and Wilmington, North Carolina, are currently in the process of being
closed under the Resource Conservation and Recovery Act.

     The Resource Conservation and Recovery Act closure process can result in
the need to conduct soil and/or groundwater remediation to address any on-site
releases. The Grenada facility is subject to an administrative order issued by
the Mississippi Department of Environmental Quality under which we will conduct
groundwater remediation. We have established a $1.8 million reserve to cover
costs of remediation at the Grenada facility and possible costs associated with
the Resource Conservation and Recovery Act closure at the Danville facility. We
also have installed and are operating a groundwater treatment system at our
previously owned facility in Ft. Worth, Texas. We have established a reserve
having a balance of approximately $200,000 to cover the projected $50,000 annual
operating costs for ongoing treatment at the Ft. Worth site. Resource
Conservation and Recovery Act closure activities at the Wilmington facility
include an ongoing groundwater remediation project. This project is being
conducted and funded by a prior owner of

                                       43
<PAGE>   44

the facility, under an indemnification obligation under the contract pursuant to
which we acquired the facility. We have no reason to believe that the prior
owner will not continue to conduct and pay for the required remediation at the
Wilmington facility. However, if the prior owner refused to meet its contractual
obligations, we could be required to complete the remediation.

     From time to time we have received notices that we are 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. At present, our
only active Superfund involvements are at the Granville Solvents Superfund Site
located in Ohio, the Envirochem Third Site in Illinois and the Operating
Industries site in California. Since 1994, we have spent an average of $49,000
per year for costs related to the Granville Solvents site and expect to incur
similar costs at the site over the next few years. Total estimated exposure
costs at the Envirochem Third Site are approximately $30,000. Marco Mfg., an
indirect subsidiary of Lennox, is one of more than 4,000 companies identified as
potentially responsible parties for the Operating Industries site. In June 1998,
Marco Mfg. received a settlement offer from the Operating Industries steering
committee to settle its liability as a de minimis party for approximately
$60,000. Marco rejected the settlement offer and has no reason to believe that
its ultimate liability will exceed the proposed settlement amount. Based on the
facts presently known, we do not believe that environmental cleanup costs
associated with these Superfund sites will have a material adverse effect on our
financial position or results of operations.

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

     - 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
our service technicians who work in the geographic area covered by the permit or
license.

LEGAL PROCEEDINGS

     We are involved in various claims and lawsuits incidental to our business.
In the opinion of our management, these claims and suits in the aggregate will
not have a material adverse effect on our business, financial condition or
results of operations.

by our Chief Executive Officer and our four other most highly compensated
executive officers, such individuals sometimes being referred to as the "named
executive officers". In the third quarter of 1998, we terminated the Lennox
International Inc. performance share plan in connection with the adoption of the
1998 incentive plan. We terminated the performance share plan to reduce
potential earnings volatility associated with the application of variable price
accounting rules to the provisions of the plan. The amounts in the LTIP Payouts
column in the Summary Compensation Table below consists of the value of common
stock issued to the named executive officers in connection with the termination
of the performance share plan and in full settlement of our obligations under
that plan. Performance awards are now granted under our 1998 incentive plan.

     We maintain a pay-for-performance compensation philosophy to pay
market-competitive base salaries, while also delivering variable pay which is
directly linked to the achievement of performance measurements and to the
performance and contribution of the individual.

     Executive compensation is composed of three primary components: base
salary, variable pay and benefits and perquisites. In order to evaluate the
competitiveness of our total compensation programs, we have periodically engaged
Hewitt Associates LLC, a human resources consulting firm, to conduct market
analyses of the compensation programs for executive level jobs within our
organization. In doing so, we emphasize delivering competitive total
compensation opportunities, while maintaining the flexibility to design
individual compensation components to support critical business objectives.

1998 INCENTIVE PLAN

     GENERAL

     Our board of directors has adopted, and our stockholders have approved, the
1998 incentive plan. The 1998 incentive plan amends and restates the 1994 stock
option and restricted stock plan. Any outstanding awards under the 1994 stock
option and restricted stock plan will remain outstanding. The objectives of the
1998 incentive plan are to attract and retain employees, to attract and retain
qualified directors and to stimulate the active interest of such persons in our
development and financial success. Awards provide participants with a
proprietary interest in our growth and performance. The description below
represents a summary of the principal terms and conditions of the 1998 incentive
plan.

     Awards to our employees or independent contractors under the 1998 incentive
plan may be made in the form of grants of stock options, stock appreciation
rights, restricted or non-restricted stock or units denominated in stock, cash
awards or performance awards or any combination of these awards. Awards to
non-employee directors under the 1998 incentive plan will be in the form of
grants of stock options.

                                       51
<PAGE>   52

     The 1998 incentive plan provides for awards to be made in respect of a
maximum of      shares of our common stock, of which      shares will be
available for awards to our employees and independent contractors and the
remainder of which will be available for awards to non-employee directors. No
participant under the 1998 incentive plan may be granted in any 12-month period
awards consisting of stock options or stock appreciation rights for more than
     shares of common stock, stock awards for more than           shares of
common stock or cash awards in excess of $       . Shares of common stock which
are the subject of awards that are forfeited or terminated or expire unexercised
will again immediately become available for awards under the 1998 incentive
plan.

     Our compensation committee will have the exclusive authority to administer
the 1998 incentive plan as it relates to employee awards and to take all actions
which are specifically contemplated by the plan or are necessary or appropriate
in connection with the administration thereof. The compensation committee may,
in its discretion:

     - provide for the extension of the exercisability of an award;

     - accelerate the vesting or exercisability of an award to our employees;

     - eliminate or make less restrictive any restrictions contained in an award
       to our employees;

     - waive any restriction or other provision of the 1998 incentive plan or in
       any award to our employees; or

     - otherwise amend or modify an award to our employees in any manner that is
       either not adverse to the employee holding the award or consented to by
       such employee.

     EMPLOYEE AWARDS

     The compensation committee will determine the type or types of awards made
under the 1998 incentive plan and will designate the employees who are to be
recipients of such awards. Each award may be embodied in an agreement, which
will contain such terms, conditions and limitations as are determined by the
compensation committee. Awards to our employees may be granted singly, in
combination or in tandem. Awards to our employees may also be made in
combination or in tandem with, in replacement of, or as alternatives to, grants
or rights under the 1998 incentive plan or any other employee plan or program of
Lennox, including any acquired entity. All or part of an award to our employees
may be subject to conditions established by the compensation committee, which
may include continuous service with Lennox, achievement of specific business
objectives, increases in specified indices, attainment of specified growth rates
and other comparable measurements of performance.

     The types of awards to our employees that may be made under the 1998
incentive plan are as follows:

     Options: Options are rights to purchase a specified number of shares of
common stock at a specified price. An option granted under the 1998 incentive
plan may consist of either an incentive stock option that complies with the
requirements of Section 422 of the Internal Revenue Code of 1986, or a
non-qualified stock option that does not comply with such requirements.
Incentive stock options must have an exercise price per share that is not less
than the fair market value of the common stock on the date of grant. To the
extent that the aggregate fair market value, measured at the time of grant, of
common stock subject to incentive stock options that first become exercisable by
an employee in any one calendar year exceeds $100,000, such options shall be
treated as non-qualified stock options and not as incentive stock options.
Non-qualified stock options must have an exercise price per share that is not
less than, but may exceed, the fair market value of the common stock on the date
of grant. In either case, the exercise price must be paid in full at the time an
option is exercised in cash or, if the employee so elects, by means of tendering
common stock or surrendering another award.

     Stock Appreciation Rights: Stock appreciation rights are rights to receive
a payment, in cash or common stock, equal to the excess of the fair market value
or other specified valuation of a specified number of shares of common stock on
the date the rights are exercised over a specified strike price. A stock
appreciation right may be granted in tandem under the 1998 incentive plan to the
holder of an option with respect to all or a portion of the shares of common
stock subject to such option or may be granted separately. The terms,
                                       52
<PAGE>   53

conditions and limitations applicable to any stock appreciation rights,
including the term of any stock appreciation rights and the date or dates upon
which they become exercisable, will be determined by our compensation committee.

     Stock Awards: Stock awards consist of grants of restricted common stock or
non-restricted common stock or units denominated in common stock. The terms,
conditions and limitations applicable to any stock awards will be determined by
our compensation committee. The compensation committee may remove any
restrictions on stock awards, at its discretion. Rights to dividends or dividend
equivalents may be extended to and made part of any stock award in the
discretion of the compensation committee.

     Cash Awards: Cash awards consist of grants denominated in cash. The terms,
conditions and limitations applicable to any cash awards will be determined by
our compensation committee.

     Performance Awards: Performance awards consist of grants made to an
employee subject to the attainment of one or more performance goals. A
performance award will be paid, vested or otherwise deliverable solely upon the
attainment of one or more pre-established, objective performance goals
established by our compensation committee prior to the earlier of (a) 90 days
after the commencement of the period of service to which the performance goals
relate and (b) the elapse of 25% of the period of service, and in any event
while the outcome is substantially uncertain. A performance goal may be based
upon one or more business criteria that apply to the employee, one or more
business units of Lennox or Lennox as a whole. The terms, conditions and
limitations applicable to any performance awards will be determined by our
compensation committee.

     DIRECTOR AWARDS

     Our board of directors will administer the 1998 incentive plan as it
relates to awards to non-employee directors. The board will have the right to
determine on an annual basis, or at any other time in its sole discretion, to
award options which are non-qualified stock options to non-employee directors.
No such options awarded in any year shall provide for the purchase of more than
     shares of common stock. All options awarded to directors shall have a term
of 10 years and shall vest and become exercisable in increments of one-third on
each of the three succeeding anniversaries after the date of grant. Unvested
options awarded to directors shall be forfeited if a director resigns without
the consent of the majority of our board of directors.

     OTHER PROVISIONS

     Our board of directors may amend, modify, suspend or terminate the 1998
incentive plan for the purpose of addressing any changes in legal requirements
or for any other purpose permitted by law, except that:

     - no amendment that would impair the rights of any employee or non-employee
       director to any award may be made without the consent of such employee or
       non-employee director; and

     - no amendment requiring stockholder approval under any applicable legal
       requirements will be effective until such approval has been obtained.

     In the event of any subdivision or consolidation of outstanding shares of
our common stock, declaration of a stock dividend payable in shares of our
common stock or other stock split, the 1998 incentive plan provides for our
board of directors to make appropriate adjustments to:

     - the number of shares of common stock reserved under the 1998 incentive
       plan;

     - the number of shares of common stock covered by outstanding awards in the
       form of common stock or units denominated in common stock;

     - the exercise or other price in respect of such awards;

     - the appropriate fair market value and other price determinations for
       awards in order to reflect such transactions; and

                                       53
<PAGE>   54

     - the limitations in the 1998 incentive plan regarding the number of awards
       which may be made to any employee in a given year.

     Furthermore, in the event of any other recapitalization or capital
reorganization of Lennox, any consolidation or merger of Lennox with another
corporation or entity, the adoption by Lennox of any plan of exchange affecting
the common stock or any distribution to holders of common stock or securities or
property, other than normal cash dividends or stock dividends, our board of
directors will make appropriate adjustments to the amounts or other items
referred to above to give effect to such transactions, but only to the extent
necessary to maintain the proportionate interest of the holders of the awards
and to preserve, without exceeding, the value of the awards.

RETIREMENT PLANS

     The named executive officers participate in four Lennox-sponsored
retirement plans. The plans are as follows: the pension plan for salaried
employees, the profit sharing retirement plan, the supplemental retirement plan,
and the profit sharing restoration plan. The supplemental retirement plan and
the profit sharing restoration plan are non-qualified plans. We pay the full
cost of all these plans.

     The pension plan for salaried employees is a floor offset plan. A target
benefit is calculated using credited service and final average pay during the
five highest consecutive years. The benefit is currently based on 1.00% of final
average pay, plus .60% of final average pay above Social Security covered
compensation, times the number of years of credited service, not to exceed 30
years. Employees vest after five years of service and may commence unreduced
benefits at age 65. If specified age and service requirements are met, benefits
may commence earlier on an actuarially reduced basis. At time of retirement, a
participant may choose one of five optional forms of payment. The supplemental
retirement plan permits income above Internal Revenue Service limitations to be
considered in determining final average pay, doubles the rate of benefit
accrual, limits credited service to 15 years and permits early retirement on
somewhat more favorable terms than the pension plan.

     The profit sharing retirement plan is a defined contribution plan. Profit
sharing contributions, as determined by our board of directors, are credited
annually to participants' accounts based on pay. Participants are fully vested
after 6 years. The assets of the plan are employer directed. Distributions may
occur at separation of employment and can be paid directly to the participant.
The restoration plan permits accruals that otherwise could not occur because of
Internal Revenue Service limitations on compensation.

     The estimates of annual retirement benefits shown in the following table
are the targets established by the supplemental retirement plan.

(1) Final Average Earnings are the average of the five highest consecutive years
    of includible earnings. Compensation for these purposes includes salary and
    bonuses, and excludes extraordinary compensation such as benefits from the
    1998 incentive plan or its predecessor plans. Bonus numbers used in these
    calculations, as per plan requirements, are the bonuses actually paid in
    those years. In the Summary Compensation Table, the 1998 bonus reported is
    the bonus earned in 1998, but not paid until 1999.

     As of December 31, 1998, the final average pay and the eligible years of
credited service for each of the named executive officers was as follows: Mr.
Norris, $855,001 -- 38.25 years; Mr. Jenkins, $483,948 --

                                       54

14.00 years; Mr. Wyant, $402,391 -- 8.30 years; Mr. Schjerven, $411,416 -- 12.80
years; Mr. French, $340,666 -- 9.80 years.

EMPLOYMENT AGREEMENTS

     We have entered into an employment agreement with each of the named
executive officers who are currently employees of Lennox. Each of the employment
agreements is identical except for the name of the named executive officer who
is a party to the agreement and the date of the agreement. These employment
agreements establish the basis of compensation and assignments; and
post-employment covenants covering confidential information, the diverting of
employees, vendors and contractors and the solicitation of customers. These
agreements also establish binding arbitration as the mechanism for resolving
disputes and provide benefits and income in the event employment terminates
under specified circumstances.

     The agreements commence on the date they are signed by both parties and
remain in effect until December 31 of that year and afterwards for a series of
one-year terms. On January 1 of each year after the end of the first term and
for each year afterwards, the agreements automatically renew for an additional
year, unless either party notifies the other, in writing, at least 30 days prior
to such date, of a decision not to renew the agreement.

     If we terminate the employee prior to the expiration of the term of the
agreement or if we do not renew the agreement for any reason other than for
cause, the employee will be entitled to receive monthly payments of the greater
of the employee's base salary for the remainder of the agreement's term or three
months of the employee's base salary in addition to any other compensation or
benefits applicable to an employee at the employee's level.

     If we terminate the employee other than for cause, including our
non-renewal of the agreement, and the employee agrees to execute a written
general release of any and all possible claims against us existing at the time
of termination, we will provide the employee with an enhanced severance package.
That package includes payment of the employee's base monthly salary for a period
of twenty-four months following the date of termination, a lump sum payment of
$12,000 in lieu of perquisites lost, and forgiveness of COBRA premiums due for
group health insurance coverage for up to eighteen months while the employee
remains unemployed. If the employee remains unemployed at the end of eighteen
months, the equivalent of the COBRA premium will be paid to the employee on a
month to month basis for up to six additional months while the employee remains
unemployed. Outplacement services are provided or, at the employee's election, a
lump-sum payment of 10% of the employee's annual base salary will be made to the
employee in lieu of those services. Additionally, the employee's beneficiary
will receive a lump-sum death benefit equivalent to six months of the employee's
base salary should the employee die while entitled to enhanced severance
payments.

CHANGE OF CONTROL EMPLOYMENT AGREEMENTS

     We have entered into a change of control employment agreement with each of
the named executive officers who are currently employees of Lennox. Each of the
change of control agreements is identical except for the name of the named
executive officer who is a party to the agreement and the date of the agreement.
The change of control agreements provide for certain benefits under specified
circumstances if the officer's employment is terminated following a change of
control transaction involving Lennox. The change of control agreements are
intended to provide protections to the officers that are not afforded by their
existing employment agreements, but not to duplicate benefits provided by the
existing employment agreements. The term of the change of control agreements is
generally two years from the date of a potential change of control, as discussed
below, or a change of control. If the officer remains employed at the conclusion
of such term, the officer's existing employment agreement will continue to
apply. The employment rights of the named executive officers under the change of
control agreements would be triggered by either a change of control or a
potential change of control. Following a potential change of control, the term
of the change of control agreement may terminate but the change of control
agreement will remain in force and a new term of the agreement will apply to any
future change of control or potential change of control, if either (a) our board
of directors determines that a change of control is not likely or (b) the named
executive officer, upon proper

                                       55
<PAGE>   56

notice to us, elects to terminate his term of the change of control agreement as
of any anniversary of the potential change of control.

     A "change of control" generally includes the occurrence on or after the
date of the offering of any of the following:

          (a) any person, other than specified exempt persons, including Lennox
     and its subsidiaries and employee benefit plans, becoming a beneficial
     owner of 35% or more of the shares of common stock or voting stock of
     Lennox then outstanding, including as a result of the offering;

          (b) a change in the identity of a majority of the persons serving as
     members of our board of directors, unless such change was approved by a
     majority of the incumbent members of our board of directors;

          (c) the approval by the stockholders of a reorganization, merger or
     consolidation in which:

             (1) existing stockholders would not own more than 65% of the common
        stock and voting stock of the resulting company;

             (2) a person, other than specified exempt persons, would own 35% or
        more of the common stock or voting stock of the resulting company; or

             (3) less than a majority of the board of the resulting company
        would consist of the then incumbent members of our board of directors;
        or

          (d) the approval by the stockholders of a liquidation or dissolution
     of Lennox, unless such liquidation or dissolution is part of a plan of
     liquidation or dissolution involving a sale to a company of which following
     such transaction:

             (1) more than 65% of the common stock and voting stock would be
        owned by existing stockholders;

             (2) no person, other than specified exempt persons, would own 35%
        or more of the common stock or voting stock of such company; and

             (3) at least a majority of the board of directors of such company
        would consist of the then incumbent members of our board of directors.

     A "potential change in control" generally includes any of the following:

     - the commencement of a tender or exchange offer for voting stock that, if
       consummated, would result in a change of control;

     - Lennox entering into an agreement which, if consummated, would constitute
       a change of control;

     - the commencement of a contested election contest subject to proxy rules;
       or

     - the occurrence of any other event that our board of directors determines
       could result in a change of control.

     During the term of the change of control agreement, an officer's position,
authority, duties and responsibilities may not be diminished, and all forms of
compensation, including salary, bonus, regular salaried employee plan benefits,
stock options, restricted stock and other awards, must continue on a basis no
less favorable than at the beginning of the term of the change of control
agreement and, in the case of specified benefits, must continue on a basis no
less favorable in the aggregate than the most favorable application of such
benefits to any of our employees.

                                       56
<PAGE>   57

     If an officer terminates employment during the term of the change of
control agreement for good reason and we fail to honor the terms of the change
of control agreement, we will pay the officer:

     - his then unpaid current salary and a pro rata portion of the highest
       bonus earned during the three preceding years, as well as previously
       deferred compensation and accrued vacation time;

     - a lump-sum benefit equal to the sum of three times the officer's annual
       base salary and three times the annual bonus he would have earned in the
       year of termination;

     - for purposes of our supplemental retirement plan and our profit sharing
       restoration plan, three additional years added to both his service and
       age criteria; and

     - continued coverage under our employee welfare benefits plans for up to
       four and one-half years.

In addition, all options, restricted stock and other compensatory awards held by
the officer will immediately vest and become exercisable, and the term of these
awards will be extended for up to one year following termination of employment.
The officer may also elect to cash out equity-based compensatory awards at the
highest price per share paid by specified persons during the term of the change
of control agreement or the six-month period prior to the beginning of the term
of the change of control agreement.

     In the event of any contest concerning a change of control agreement in
which the officer is successful, in whole or in part, on the merits:

     - we have no right of offset;

     - the officer is not required to mitigate damages; and

     - we agree to pay any legal fees incurred by the officer in connection with
       such contest.

     We also agree to pay all amounts owing to the officer during any period of
dispute, subject only to the officer's agreement to repay any amounts to which
he is determined not to be entitled. The change of control agreements provide
for a tax gross-up in the event that specified excise taxes are applicable to
payments made by us under a change of control agreement or otherwise. The change
of control agreements require the officer to maintain the confidentiality of our
information, and, for a period of 24 months following his termination of
employment, to avoid any attempts to induce our employees to terminate their
employment with us.

INDEMNIFICATION AGREEMENTS

     We have entered into indemnification agreements with our directors and a
number of our executive officers. Each of the indemnification agreements is
identical except for the name of the director or executive officer who is a
party to the agreement and the date of the agreement. Under the terms of the
indemnification agreements, we have generally agreed to indemnify, and advance
expenses to, each indemnitee to the fullest extent permitted by applicable law
on the date of the agreements and to such greater extent as applicable law may
at a future time permit. In addition, the indemnification agreements contain
specific provisions pursuant to which we have agreed to indemnify each
indemnitee:

     - if such person is, by reason of his or her status as a director, nominee
       for director, officer, agent or fiduciary of ours or of any other
       corporation, partnership, joint venture, trust, employee benefit plan or
       other enterprise with which such person was serving at our request, any
       such status being referred to as a "corporate status," made or threatened
       to be made a party to any threatened, pending or completed action, suit,
       arbitration, alternative dispute resolution mechanism, investigation or
       other proceeding, other than a proceeding by or in the right of Lennox;

     - if such person is, by reason of his or her corporate status, made or
       threatened to be made a party to any proceeding brought by or in the
       right of Lennox to procure a judgment in its favor, except that no
       indemnification shall be made in respect of any claim, issue or matter in
       such proceeding as to which such indemnitee shall have been adjudged to
       be liable to Lennox if applicable law prohibits such indemnification,
       unless and only to the extent that a court shall otherwise determine;

                                       57
<PAGE>   58

     - against expenses actually and reasonably incurred by such person or on
       his or her behalf in connection with any proceeding to which such
       indemnitee was or is a party by reason of his or her corporate status and
       in which such indemnitee is successful, on the merits or otherwise;

     - against expenses actually and reasonably incurred by such person or on
       his or her behalf in connection with a proceeding to the extent that such
       indemnitee is, by reason of his or her corporate status, a witness or
       otherwise participates in any proceeding at a time when such person is
       not a party in the proceeding; and

     - against expenses actually and reasonably incurred by such person in
       certain judicial adjudications of or awards in arbitration to enforce his
       or her rights under the indemnification agreements.

     In addition, under the terms of the indemnification agreements, we have
agreed to pay all reasonable expenses incurred by or on behalf of an indemnitee
in connection with any proceeding, whether brought by or in the right of Lennox
or otherwise, in advance of any determination with respect to entitlement to
indemnification and within 15 days after the receipt by us of a written request
from such indemnitee for such payment. In the indemnification agreements, each
indemnitee has agreed that he or she will reimburse and repay us for any
expenses so advanced to the extent that it shall ultimately be determined that
he or she is not entitled to be indemnified by us against such expenses.

     The indemnification agreements also include provisions that specify the
procedures and presumptions which are to be employed to determine whether an
indemnitee is entitled to indemnification. In some cases, the nature of the
procedures specified in the indemnification agreements varies depending on
whether we have undergone a change in control.

                             PRINCIPAL STOCKHOLDERS

     The following table contains information regarding the beneficial ownership
of our common stock as of May 31, 1999 by the following individuals:

     - each person known by us to own more than 5% of the outstanding shares of
       common stock;

     - each of our directors;

     - each named executive officer; and

     - all executive officers and directors as a group.

All persons listed have an address in care of our principal executive offices
and have sole voting and investment power of their shares unless otherwise
indicated.

     The information contained in this table reflects "beneficial ownership" as
defined in Rule 13d-3 of the Securities Exchange Act of 1934. In computing the
number of shares beneficially owned by a person and the percentage ownership of
that person, shares of common stock subject to options held by that person that
were exercisable on May 31, 1999 or became exercisable within 60 days following
May 31, 1999 are considered outstanding. However, such shares are not considered
outstanding for the purpose of computing the percentage ownership of any other
person. To our knowledge and unless otherwise indicated, each stockholder has
sole voting and investment power over the shares listed as beneficially owned by
such stockholder, subject to community property laws where applicable.
Percentage of ownership is based on      shares of common stock outstanding as
of May 31, 1999 and      shares of common stock outstanding after the completion
of the offering assuming no exercise of the underwriters' over-allotment option.
As of May 31, 1999, we had approximately           holders of our common stock.

              CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

     John W. Norris, Jr., our Chairman and Chief Executive Officer, and David H.
Anderson, Richard W. Booth and David V. Brown, each one of our directors, as
well as some of our stockholders, are members of AOC Land Investment, LLC. AOC
Land Investment, LLC owns 70% of AOC Development II, LLC. AOC Development II,
LLC is building a new office building and we have agreed to lease part of it for
use as our corporate headquarters. The lease will have a term of 25 years and
the annual lease payments are expected to be approximately $2.1 million per year
for the first five years. We believe that the terms of our lease with AOC
Development II, LLC are at least as favorable as could be obtained from
unaffiliated third parties.

     From time to time we have entered into stock disposition agreements which
allowed our executives, directors and stockholders to borrow money and use our
capital stock held by them as collateral. The stock disposition agreements
provided that in the event of a default on the underlying loan, we would do one
of several things, including registering the capital stock under the Securities
Act of 1933 finding a buyer to purchase the stock or purchasing the stock
ourself. There were never any defaults under these agreements. Currently, there
are stock disposition agreements in existence covering      shares of common
stock. We will not enter into these type of agreements in the future.

     These transactions were not the result of arms-length negotiations.
Accordingly certain of the terms of these transactions may be more or less
favorable to us than might have been obtained from unaffiliated third parties.
We do not intend to enter into any future transactions in which our directors,
executive officers or principal stockholders and their affiliates have a
material interest unless such transactions are approved by a majority of the
disinterested members of our board of directors and are on terms that are no
less favorable to us than those that we could obtain from unaffiliated third
parties.

                          DESCRIPTION OF CAPITAL STOCK

     Our authorized capital stock consists of 200,000,000 shares of common stock
and 25,000,000 shares of preferred stock, par value $.01 per share. At
            , 1999,           shares of common stock were outstanding. None of
the preferred stock is outstanding.

COMMON STOCK

     The holders of common stock are entitled to one vote per share on all
matters to be voted on by stockholders. Generally, all matters to be voted on by
stockholders must be approved by a majority (or, in the case of election of
directors, by a plurality) of the votes entitled to be cast by all shares of
common stock present in person or represented by proxy, voting together as a
single class, except as may be required by law and subject to any voting rights
granted to holders of any preferred stock. However, the removal of a director
from office, the approval and authorization of specified business combinations
and amendments to specified provisions of our certificate of incorporation each
require the approval of not less than 80% of the combined voting power of our
outstanding shares of stock entitled to vote generally in the election of
directors, voting together as a single class. See "-- Certificate of
Incorporation and Bylaw Provisions". The common stock does not have cumulative
voting rights.

     Subject to the prior rights of the holders of any shares of our preferred
stock, the holders of common stock shall be entitled to receive, to the extent
permitted by law, such dividends as may be declared from time to time by our
board of directors. On our liquidation, dissolution or winding up, after payment
in full of the amounts required to be paid to holders of preferred stock, if
any, all holders of common stock are entitled to share ratably in any assets
available for distribution to holders of shares of common stock.

     The outstanding shares of common stock are legally issued, fully paid and
nonassessable. The common stock does not have any preemptive, subscription or
conversion rights. Additional shares of authorized common stock may be issued,
as authorized by our board of directors from time to time, without stockholder
approval, except as may be required by applicable stock exchange requirements.

                                       61
<PAGE>   62

PREFERRED STOCK

     As of the date of this prospectus, no shares of preferred stock are
outstanding. Our board of directors may authorize the issuance of preferred
stock in one or more series and may determine, for the series, the designations,
powers, preferences and rights of such series, and the qualifications,
limitations and restrictions of the series, including:

     - the designation of the series;

     - the consideration for which the shares of any such series are to be
       issued;

     - the rate or amount per annum, if any, at which holders of the shares of
       such series shall be entitled to receive dividends, the dates on which
       such dividends shall be payable, whether the dividends shall be
       cumulative or noncumulative, and if cumulative, the date or dates from
       which such dividends shall be cumulative;

     - the redemption rights and price or prices, if any, for shares of the
       series;

     - the amounts payable on and the preferences, if any, of shares of the
       series in the event of dissolution or upon distribution of our assets;

     - whether the shares of the series will be convertible into or exchangeable
       for other of our securities, and the price or prices or rate or rates at
       which conversion or exchange shall be exercised;

     - the terms and amounts of any sinking fund provided for the purchase or
       redemption of shares of the series;

     - the voting rights, if any, of the holders of shares of the series; and

     - such other preferences and rights, privileges and restrictions applicable
       to any such series as may be permitted by law.

     We believe that the ability of our board of directors to issue one or more
series of preferred stock will provide us with flexibility in structuring
possible future financings and acquisitions and in meeting other corporate needs
that might arise. The authorized shares of preferred stock will be available for
issuance without further action by our stockholders, unless such action is
required by applicable law or the rules of any stock exchange on which our
securities may be listed or traded.

     Although our board of directors has no intention at the present time of
doing so, it could issue a series of preferred stock that could, depending on
the terms of such series, impede the completion of a merger, tender offer or
other takeover attempt. Our board of directors will make any determination to
issue such shares based on its judgment as to our best interests and the best
interests of our stockholders. Our board of directors, in so acting, could issue
preferred stock having terms that could discourage a potential acquiror from
making, without first negotiating with our board of directors, an acquisition
attempt through which such acquiror may be able to change the composition of our
board of directors, including a tender offer or other transaction that some, or
a majority, of our stockholders might believe to be in their best interests or
in which stockholders might receive a premium for their stock over the then
current market price of such stock.

BUSINESS COMBINATION STATUTE

     As a corporation organized under the laws of the State of Delaware, we will
be subject to Section 203 of the Delaware General Corporation Law, which
restricts specified business combinations between us and an "interested
stockholder" or its affiliates or associates for a period of three years
following the time that the stockholder becomes an "interested stockholder." In
general, an "interested stockholder" is defined as a stockholder owning 15% or
more of our outstanding voting stock. The restrictions do not apply if:

     - prior to an interested stockholder becoming such, our board of directors
       approved either the business combination or the transaction which
       resulted in the stockholder becoming an interested stockholder;

                                       62
<PAGE>   63

     - upon completion of the transaction which resulted in any person becoming
       an interested stockholder, such interested stockholder owns at least 85%
       of our voting stock outstanding at the time the transaction commenced,
       excluding shares owned by employee stock ownership plans and persons who
       are both directors and officers of Lennox; or

     - at or subsequent to the time an interested stockholder becomes such, the
       business combination is both approved by our board of directors and
       authorized at an annual or special meeting of our stockholders, not by
       written consent, by the affirmative vote of at least 66 2/3% of the
       outstanding voting stock not owned by the interested stockholder.

     Under some circumstances, Section 203 makes it more difficult for a person
who would be an "interested stockholder" to effect various business combinations
with a corporation for a three-year period, although the stockholders may elect
to exclude a corporation from the restrictions imposed under Section 203. Our
certificate of incorporation does not exclude us from the restrictions imposed
under Section 203. It is anticipated that the provisions of Section 203 may
encourage companies interested in acquiring us to negotiate in advance with our
board of directors since the stockholder approval requirement would be avoided
if a majority of the directors then in office approves, prior to the date on
which a stockholder becomes an interested stockholder, either the business
combination or the transaction which results in the stockholder becoming an
interested stockholder.

CERTIFICATE OF INCORPORATION AND BYLAW PROVISIONS

     The summary below describes provisions of our certificate of incorporation
and bylaws. The provisions of our certificate of incorporation and bylaws
discussed below may have the effect, either alone or in combination with the
provisions of Section 203 discussed above, of making more difficult or
discouraging a tender offer, proxy contest or other takeover attempt that is
opposed by our board of directors but that a stockholder might consider to be in
such stockholder's best interest. Those provisions include:

     - restrictions on the rights of stockholders to remove directors;

     - prohibitions against stockholders calling a special meeting of
       stockholders or acting by unanimous written consent in lieu of a meeting;

     - requirements for advance notice of actions proposed by stockholders for
       consideration at meetings of the stockholders; and

     - restrictions on business combination transactions with "related persons."

     CLASSIFIED BOARD OF DIRECTORS; REMOVAL; NUMBER OF DIRECTORS; FILLING
VACANCIES

     Our certificate of incorporation and bylaws provide that the board of
directors shall be divided into three classes, designated Class I, Class II and
Class III, with the classes to be as nearly equal in number as possible. The
term of office of each class shall expire at the third annual meeting of
stockholders for the election of directors following the election of such class.
See "Management -- Information Regarding the Board of Directors and Committees"
for a discussion of the directors in each class. Each director is to hold office
until his or her successor is duly elected and qualified, or until his or her
earlier resignation or removal.

     Our bylaws provide that the number of directors will be fixed from time to
time by to a resolution adopted by the board of directors; provided that the
number so fixed shall not be more than 15 nor less than three directors. Our
bylaws also provide that any vacancies will be filled only by the affirmative
vote of a majority of the remaining directors, even if less than a quorum.
Accordingly, absent an amendment to the bylaws, our board of directors could
prevent any stockholder from enlarging the board of directors and filling the
new directorships with such stockholder's own nominees. Moreover, our
certificate of incorporation and bylaws provide that directors may be removed
only for cause and only upon the affirmative vote of holders of at least 80% of
our voting stock at a special meeting of stockholders called expressly for that
purpose.

     The classification of directors could have the effect of making it more
difficult for stockholders to change the composition of the board of directors.
At least two annual meetings of stockholders, instead of one, are
                                       63
<PAGE>   64

generally required to effect a change in a majority of the board of directors.
Such a delay may help ensure that our directors, if confronted by a holder
attempting to force a proxy contest, a tender or exchange offer, or an
extraordinary corporate transaction, would have sufficient time to review the
proposal as well as any available alternatives to the proposal and to act in
what they believe to be the best interest of the stockholders. The
classification provisions will apply to every election of directors, however,
regardless of whether a change in the composition of the board of directors
would be beneficial to us and our stockholders and whether or not a majority of
our stockholders believe that such a change would be desirable.

     The classification provisions could also have the effect of discouraging a
third party from initiating a proxy contest, making a tender offer or otherwise
attempting to obtain control of us, even though such an attempt might be
beneficial to us and our stockholders. The classification of the board of
directors could thus increase the likelihood that incumbent directors will
retain their positions. In addition, because the classification provisions may
discourage accumulations of large blocks of our stock by purchasers whose
objective is to take control of us and remove a majority of the board of
directors, the classification of the board of directors could tend to reduce the
likelihood of fluctuations in the market price of the common stock that might
result from accumulations of large blocks. Accordingly, stockholders could be
deprived of opportunities to sell their shares of common stock at a higher
market price than might otherwise be the case.

     NO STOCKHOLDER ACTION BY WRITTEN CONSENT; SPECIAL MEETINGS

     Our certificate of incorporation and bylaws provide that stockholder action
can be taken only at an annual or special meeting of stockholders and
stockholder action may not be taken by written consent in lieu of a meeting.
Special meetings of stockholders can be called only by our board of directors by
a resolution adopted by a majority of the board of directors, or by the chairman
of the board, vice chairman or the president. Moreover, the business permitted
to be conducted at any special meeting of stockholders is limited to the
business brought before the meeting under the notice of meeting given by us.

     The provisions of our certificate of incorporation and bylaws prohibiting
stockholder action by written consent and permitting special meetings to be
called only by the chairman, vice chairman or president, or at the request of a
majority of the board or directors, may have the effect of delaying
consideration of a stockholder proposal until the next annual meeting. The
provisions would also prevent the holders of a majority of our voting stock from
unilaterally using the written consent procedure to take stockholder action.
Moreover, a stockholder could not force stockholder consideration of a proposal
over the opposition of the chairman, vice chairman or president, or a majority
of the board of directors, by calling a special meeting of stockholders prior to
the time such parties believe such consideration to be appropriate.

     ADVANCE NOTICE PROVISIONS FOR STOCKHOLDER NOMINATIONS AND STOCKHOLDER
PROPOSALS

     Our bylaws establish an advance notice procedure for stockholders to make
nominations of candidates for election as directors or bring other business
before an annual meeting of stockholders.

     The stockholder notice procedure provides that only persons who are
nominated by, or at the direction of, the board of directors, or by a
stockholder who has given timely written notice containing specified information
to our secretary prior to the meeting at which directors are to be elected, will
be eligible for election as our directors. The stockholder notice procedure also
provides that at an annual meeting only such business may be conducted as has
been brought before the meeting by, or at the direction of, the chairman of the
board of directors, or in the absence of the chairman of the board, the
president, or by a stockholder who has given timely written notice containing
specified information to our secretary of such stockholder's intention to bring
such business before such meeting. Under the stockholder notice procedure, for
notice of stockholder nominations or proposals to be made at an annual meeting
to be timely, such notice must be received by us not less than 60 days nor more
than 90 days in advance of such meeting. For notice of stockholder nominations
or proposals to be made at a special meeting of stockholders to be timely, such
notice must be received by us not later than the close of business on the tenth
day following the date on which notice of such meeting is first given to
stockholders. However, in the event that less than 70 days notice or prior
public disclosure of the date of the meeting of stockholders is given or made to
the stockholders, to be timely, notice of a nomination or

                                       64
<PAGE>   65

proposal delivered by the stockholder must be received by our secretary not
later than the close of business on the tenth day following the day on which
notice of the date of the meeting of stockholders was mailed or such public
disclosure was made to the stockholders. If the board of directors or,
alternatively, the presiding officer at a meeting, in the case of a stockholder
proposal, or the chairman of the meeting, in the case of a stockholder
nomination to the board of directors, determines at or prior to the meeting that
business was not brought before the meeting or a person was not nominated in
accordance with the stockholder notice procedure, such business will not be
conducted at such meeting, or such person will not be eligible for election as a
director, as the case may be.

     By requiring advance notice of nominations by stockholders, the stockholder
notice procedure will afford our board of directors an opportunity to consider
the qualifications of the proposed nominees and, to the extent considered
necessary or desirable by the board of directors, to inform stockholders about
such qualifications. By requiring advance notice of other proposed business, the
stockholder notice procedure will also provide a more orderly procedure for
conducting annual meetings of stockholders and, to the extent considered
necessary or desirable by the board of directors, will provide the board of
directors with an opportunity to inform stockholders, prior to such meetings, of
any business proposed to be conducted at such meetings, together with any
recommendations as to the board of directors' position regarding action to be
taken regarding such business, so that stockholders can better decide whether to
attend such a meeting or to grant a proxy regarding the disposition of any such
business.

     Although our bylaws do not give the board of directors any power to approve
or disapprove stockholder nominations for the election of directors or proposals
for action, they may have the effect of precluding a contest for the election of
directors or the consideration of stockholder proposals if the proper procedures
are not followed, and of discouraging or deterring a third party from conducting
a solicitation of proxies to elect its own slate of directors or to approve its
own proposal, without regard to whether consideration of such nominees or
proposals might be harmful or beneficial to us and our stockholders.

     FAIR PRICE PROVISION

     Our certificate of incorporation contains a "fair price" provision that
applies to specified business combination transactions involving any person,
entity or group that beneficially owns at least 10% of our aggregate voting
stock -- such person, entity or group is sometimes referred to as a "related
person". This provision requires the affirmative vote of the holders of not less
than 80% of our voting stock to approve specified transactions between a related
person and us or our subsidiaries, including:

     - any merger, consolidation or share exchange;

     - any sale, lease, exchange, mortgage, pledge, transfer or other
       disposition of our assets, or the assets of any of our subsidiaries
       having a fair market value of more than 10% of our total consolidated
       assets, or assets representing more than 10% of our earning power and our
       subsidiaries taken as a whole, which is referred to as a "substantial
       part";

     - any sale, lease, exchange, mortgage, pledge, transfer or other
       disposition to or with us or any of our subsidiaries of all or a
       substantial part of the assets of a related person;

     - the issuance or transfer of any of our securities or any of our
       subsidiaries by us or any of our subsidiaries to a related person;

     - any reclassification of securities, recapitalization, or any other
       transaction involving us or any of our subsidiaries that would have the
       effect of increasing the voting power of a related person;

     - the adoption of a plan or proposal for our liquidation or dissolution
       proposed by or on behalf of a related person;

     - the acquisition by or on behalf of a related person of shares
       constituting a majority of our voting power; and

                                       65
<PAGE>   66

     - the entering into of any agreement, contract or other arrangement
       providing for any of the transactions described above.

     This voting requirement will not apply to certain transactions, including:

          (a) any transaction approved by a two-thirds vote of the continuing
     directors; or

          (b) any transaction in which:

             (1) the consideration to be received by the holders of common
        stock, other than the related person involved in the business
        combination, is not less in amount than the highest per share price paid
        by the related person in acquiring any of its holdings of common stock;
        and

             (2) if necessary, a proxy statement complying with the requirements
        of the Securities Exchange Act of 1934 shall have been mailed at least
        30 days prior to any vote on such business combination to all of our
        stockholders for the purpose of soliciting stockholder approval of such
        business combination.

     This provision could have the effect of delaying or preventing a change in
control of us in a transaction or series of transactions that did not satisfy
the "fair price" criteria.

     LIABILITY OF DIRECTORS; INDEMNIFICATION

     Our certificate of incorporation provides that a director will not be
personally liable for monetary damages to us or our stockholders for breach of
fiduciary duty as a director, except for liability:

     - for any breach of the director's duty of loyalty to us or our
       stockholders;

     - for acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;

     - for paying a dividend or approving a stock repurchase in violation of
       Section 174 of the Delaware General Corporation Law; or

     - for any transaction from which the director derived an improper personal
       benefit.

     Any amendment or repeal of such provision shall not adversely affect any
right or protection of a director existing under such provision for any act or
omission occurring prior to such amendment or repeal.

     Our bylaws provide that each person who at any time serves or served as one
of our directors or officers, or any person who, while one of our directors or
officers, is or was serving at our request as a director or officer of another
corporation, partnership, joint venture, trust or other enterprise, shall be
entitled to indemnification and the advancement of expenses from us, and to the
fullest extent, permitted by Section 145 of the Delaware General Corporation Law
or any successor statutory provision. We will indemnify any person who was or is
a party to any threatened, pending or completed action, suit or proceeding
because he or she is or was one of our directors or officers, or is or was
serving at our request as a director or officer of another corporation,
partnership or other enterprise. However, as provided in Section 145, this
indemnification will only be provided if the indemnitee acted in good faith and
in a manner he or she reasonably believed to be in, or not opposed to, our best
interests.

     AMENDMENTS

     Our certificate of incorporation provides that we reserve the right to
amend, alter, change, or repeal any provision contained in our certificate of
incorporation, and all rights conferred to stockholders are granted subject to
such reservation. The affirmative vote of holders of not less than 80% of our
voting stock, voting together as a single class, shall be required to alter,
amend, adopt any provision inconsistent with or repeal specified provisions of

                        SHARES ELIGIBLE FOR FUTURE SALE

     Future sales of substantial amounts of common stock in the public market
could adversely affect prevailing market prices.

     At        , 1999,        shares of common stock were outstanding. Of these
shares, the        shares of common stock sold in our initial public offering
are freely tradable without restrictions or further registration under the
Securities Act of 1933, except that shares purchased by an "affiliate" of ours,
as that term is defined in Rule 144 under the Securities Act of 1933, are
subject to the resale limitations of Rule 144. The remaining        shares of
common stock outstanding are "restricted securities" as that term is defined by
Rule 144.

     In general, under Rule 144 as currently in effect, if a period of at least
one year has elapsed after the later of the date on which "restricted" shares
were acquired from us or the date on which they were acquired from an
"affiliate," then the holder of these shares, including an affiliate, is
entitled to sell a number of shares within any three-month period that does not
exceed the greater of:

     - one percent of the then outstanding shares of the common stock; or

     - the average weekly reported volume of trading of the common stock during
       the four calendar weeks preceding such sale.

     Sales under Rule 144 are also subject to requirements pertaining to the
manner of such sales, notices of such sales and the availability of current
public information concerning Lennox. Affiliates may sell shares not
constituting "restricted" shares in accordance with the above volume limitations
and other requirements but without regard to the one-year period. Under Rule
144(k), if a period of at least two years has elapsed between the later of the
date on which "restricted" shares were acquired from us and the date on which
they were acquired from an affiliate, a holder of such shares who is not an
affiliate at the time of the sale and has not been an affiliate for at least
three months prior to the sale would be entitled to sell the shares immediately
without regard to the volume limitations and other conditions described above.
This description of Rule 144 is not intended to be a complete description
thereof.

     Sales of significant amounts of the common stock, or the perception that
such sales could occur, could have an adverse impact on the market price of the
common stock.

     In connection with our initial public offering, each of Lennox and its
directors, executive officers, the selling stockholders and certain other
stockholders of Lennox agreed that, without the prior written consent of Morgan
Stanley & Co. Incorporated on behalf of the underwriters, it will not, during
the period ending      , 1999:

     - offer, pledge, sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant to purchase or otherwise transfer or dispose of,
       directly or indirectly, any shares of common stock or any securities
       convertible into or exercisable or exchangeable for common stock; or

     - enter into any swap or other arrangement that transfers to another, in
       whole or in part, any of the economic consequences of ownership of the
       common stock;

whether any transaction described above is to be settled by delivery of common
stock or such other securities, in cash or otherwise. However, any such person
or entity may make a bona fide gift of shares during the restricted period if
the person or entity delivers to Morgan Stanley & Co. Incorporated an agreement
substantially similar to the above executed by the donee.

     The restrictions described in the previous paragraph do not apply to:

     - transactions by any person other than Lennox relating to shares of common
       stock or other securities acquired in open market transactions after the
       completion of our initial public offering of the shares;

     - the issuance or sale of shares of common stock pursuant to Lennox stock
       option plans existing on the date of completion of our initial public
       offering;

                                       68
<PAGE>   69

     - the granting by Lennox of stock options and/or performance share awards
       pursuant to Lennox's employee benefit plans; or

     - the issuance of up to           shares of common stock in connection with
       acquisitions.

In the event that consent to a waiver of these restrictions is requested by
Lennox or any such person, Morgan Stanley & Co. Incorporated will consider the
specific facts and circumstances of the request in deciding whether to grant its
consent.

     Pursuant to Rule 145 under the Securities Act of 1933, the volume
limitations and some other requirements of Rule 144 will apply to resales of the
shares of common stock covered by this prospectus by affiliates of the
businesses we acquire for a period of one year from the date of their
acquisition or such shorter period as the Securities and Exchange Commission may
prescribe. Otherwise, these securities will be freely tradeable after their
issuance by persons not affiliated with us unless we contractually restrict
their sale.

                              PLAN OF DISTRIBUTION

     This prospectus covers the offer and sale of up to           shares of our
common stock which we may offer from time to time in connection with future
direct and indirect acquisitions of other businesses, properties or securities
in business combination transactions. In addition to the shares of common stock
offered by this prospectus, we may offer other consideration, including stock
options, cash, notes or other evidences of debt, assumption of liabilities
and/or a combination of these types of consideration. In addition, we may lease
property from, and enter into management agreements and consulting and
noncompetition agreements with, the former owners and key executive personnel of
the businesses to be acquired.

     We expect that we will determine the terms on which we may issue the shares
of common stock covered by this prospectus by direct negotiations with the
owners or controlling persons of the business or assets to be acquired and that
the shares of common stock issued will be valued at prices reasonably related to
market prices prevailing either at the time an acquisition agreement is executed
or at or about the time of delivery of those shares.

     In an effort to maintain an orderly market in the common stock or for other
reasons, we may negotiate agreements with persons receiving common stock covered
by this prospectus that will limit the number of shares that such persons may
sell for specified periods. These agreements may be more restrictive than
restrictions on sales made pursuant to the exemption from registration
requirements of the Securities Act of 1933, including the requirements under
Rule 144 or Rule 145, and the persons party to these agreements may not
otherwise be subject to the Securities Act requirements.

                                 LEGAL MATTERS

     The validity of the issuance of the shares of common stock offered by this
prospectus will be passed upon for us by Baker & Botts, L.L.P., Dallas, Texas.

                                    EXPERTS

     Our financial statements and schedule as of December 31, 1997 and 1998 and

this prospectus and elsewhere in the registration statement have been audited by
Arthur Andersen LLP, independent public accountants, as indicated in their
report which is included in this prospectus, and are included in this prospectus

                                  (UNAUDITED)

1. BASIS OF PRESENTATION AND OTHER ACCOUNTING INFORMATION

     The accompanying unaudited consolidated balance sheet as of March 31, 1999,
and the consolidated statements of income and cash flows for the three months
ended March 31, 1998 and 1999 should be read in conjunction with Lennox
International Inc.'s (the "Company") consolidated financial statements and
accompanying footnotes as of December 31, 1997 and 1998 and for each of the
three years in the period ended December 31, 1998 included elsewhere herein. In
the opinion of management, the accompanying consolidated financial statements
contain all material adjustments, consisting principally of normal recurring
adjustments, necessary for a fair presentation of the Company's financial
position, results of operations, and cash flows. Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to applicable rules and regulations, although the Company
believes that the disclosures herein are adequate to make the information
presented not misleading. The operating results for the interim periods are not
necessarily indicative of the results to be expected for a full year.

     The Company's fiscal year ends on December 31 of each year, and the
Company's fiscal quarters are each comprised of 13 weeks. For convenience,
throughout these financial statements, the 13 weeks comprising each three month
period are denoted by the last day of the respective calendar quarter.

2. 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 has offered the owners of all Pulse furnaces
installed between 1982 and 1990 a subsidized inspection and a free carbon
monoxide detector. The inspection includes a severe pressure test to determine
the serviceability of the heat exchanger. If the heat exchanger does not pass
the test, the Company will either replace the heat exchanger or offer a new
furnace and subsidize the labor costs for installation. The cost required for
the program depends on the number of furnaces located, the percentage of those
located that do not pass the pressure test, and the replacement option chosen by
the homeowner.

     As of March 31, 1999, the Company had incurred approximately $126.4 million
in costs related to the product inspection program. Consequently, there is a
current liability of $13.6 million recorded on the accompanying consolidated
balance sheet as of March 31, 1999 to accrue for the estimated remaining costs
of the program. The product inspection program ends in June 1999 and the Company
believes its current liability of $13.6 million is adequate to cover the
remaining costs of the program.

3. REPORTABLE BUSINESS SEGMENTS

     As of December 31, 1998, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 131, which requires disclosure of business
segment data in accordance with the "management approach." The management
approach is based on the way segments are organized within the Company for

                   LENNOX INTERNATIONAL INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              FOR THE YEARS ENDED DECEMBER 31, 1996, 1997 AND 1998

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 these 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 $4.8 million, $6.4 million and
$4.5 million for the years ended December 31, 1996, 1997 and 1998, 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 $16.9 million and $18.5 million as of December 31, 1997 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 $125.5 million and $169.6 million in 1997 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 on the first-in,
first-out (FIFO) basis.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment is stated at cost. 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
</TABLE>

     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, 1997 and 1998, accumulated amortization was $26.5 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 1996, 1997 and 1998.

     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 $14.6 million, $17.7 million and $15.6 million for
the years ended December 31, 1996, 1997, and 1998, 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 $155.7 million and
$83.2 million as of December 31, 1997 and 1998, respectively, and are included
in the following captions on the accompanying consolidated balance sheets (in
thousands):

     Liabilities for estimated warranty expense as of December 31, 1997 and
1998, include approximately $113.4 million and $27.3 million, respectively, in
remaining estimated liabilities associated with a product inspection program
initiated in 1997 (see Note 3).

     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 $23.2 million, $25.4 million, and $33.3 million for the
years ended December 31, 1996, 1997, and 1998, 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 $36.4 million, $37.9 million, and $50.2 million for the years ended
December 31, 1996, 1997, and 1998, 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 $943,000,
$(1,955,000), and $(1,602,000) for the years ended December 31, 1996, 1997, and
1998, 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 $4.1
million and $2.1 million as of December 31, 1997 and 1998, respectively.

     These contracts require the Company to exchange French francs for U.S.
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 currency translation
adjustments on the accompanying 1996, 1997 and 1998 consolidated statements of
stockholders' equity.

     The Company from time to time enters into foreign currency exchange
contracts to hedge receivables from its foreign subsidiaries, 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 receivables being hedged. As of December
31, 1998, the Company had obligations to deliver $33.2 million of various
foreign currencies within the next three months, for which the counterparties to
the contracts will pay fixed contract amounts. The fair values of such contracts
were insignificant as of 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, 1998, the
Company had contracts to purchase 19.8 million pounds of copper over the next 24
months at fixed prices that average $0.76 per pound ($15.1 million) and
contracts to purchase 6 million pounds of copper at a variable price equal to
the COMEX copper price ($0.72 per pound at December 31, 1998) over the next 12
months. The Company also had contracts to purchase 23.4 million pounds of
aluminum at $0.68 per pound ($15.9 million) over the next 12 months. The fair
value of the copper and aluminum purchase commitments was insignificant as of
December 31, 1997 and was a liability of $2.6 million at December 31, 1998.

     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.

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 has offered the owners of Pulse furnaces installed
between 1982 and 1990 a subsidized inspection and a free carbon monoxide
detector. The inspection includes a severe pressure test to determine the
serviceability of the heat exchanger. If the heat exchanger does not pass the
test, the Company will either replace the heat exchanger or offer a new furnace
and subsidize the labor costs for installation. The cost required for the
program depends on the number of furnaces located, the percentage of those
located that do 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 ends in June 1999
and the Company believes its current liability of $27.3 million is adequate to
cover the remaining costs of the program.

4. REPORTABLE BUSINESS SEGMENTS:

     As of December 31, 1998, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 131, which requires disclosure of business
segment data in accordance with 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 (in thousands):

(1) The Heat transfer segment had intersegment sales of $34,911, $23,571, and
    $32,307 in 1996, 1997, and 1998, respectively.

(2) Includes a $140.0 million charge in 1997 related to a product inspection
    program (see Note 3).

(3) The increase in corporate and other from 1997 to 1998 is primarily due to
    $7.1 million of expense for the settlement of a lawsuit in 1998 and $4.6
    million associated with increased expenses of the Company's Performance
    Plan.

(4) The decrease in corporate and other is primarily due to a reduction in cash
    and cash equivalents of approximately $120 million.

7. INVESTMENTS IN JOINT VENTURES AND SUBSIDIARIES:

     ALLIANCE

     In 1994, the Company acquired a 50% interest in a joint venture, Alliance
Compressors, with American Standard Inc.'s Trane subsidiary ("Trane") to
develop, manufacture, and market both reciprocating and scroll compressor
products.

     In December 1996, Alliance Compressors was restructured to admit a new
partner, Copeland Corporation, and to focus solely on the development,
manufacturing, and marketing of scroll compressors. In connection with the
restructuring, the net assets associated with the reciprocating compressor
business were distributed equally to the Company and Trane. The Company
subsequently sold its share of the reciprocating compressor net assets to Trane.
In addition, the Company and Trane sold portions of their interests in Alliance
Compressors to Copeland Corporation. As a result, Alliance Compressors is now
owned 51% by Copeland Corporation, 24.5% by the Company, and 24.5% by Trane.
During 1996, the Company recognized a pretax gain of $4.6 million as a result of
the restructuring, which is included in other operating expense, net on the
accompanying 1996 consolidated statement of income. The Company's investment in
Alliance Compressors at December 31, 1998, is $6.1 million and is being
accounted for using the equity method of accounting.

     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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

50%. The aggregate purchase price for these acquisitions was approximately $22
million in cash. The aggregate purchase price exceeded the Company's interests
in the underlying equity in the ventures at the date of acquisition. As a
result, the Company recorded goodwill of approximately $2.9 million, which is
being amortized on a straight-line basis over a 30-year period.

     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,
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 this acquisition was $18.4
million, of which $10 million was in cash and $8.4 million was in Company stock
(19,133 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. on March 31, 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 pro forma results as if the Company's 70%
interest in Ets. Brancher had been consolidated beginning January 1, 1996 (in
thousands, except per share data).

     CANADIAN DEALERS

     In the fourth quarter of 1998, the Company's Lennox Industries (Canada)
Ltd. subsidiary, which is included in the North American residential segment,
purchased for cash fourteen dealers (the "Dealers") in Canada that had been
independent retail outlets of the Company's products. The aggregate purchase
price of the Dealers was $22.9 million in cash. These acquisitions were
accounted for in accordance with the purchase method of accounting. The purchase
price of each Dealer has been allocated to the assets and liabilities of the
Dealers, and the excess of $19.0 million has been allocated to goodwill, which
is being amortized on a straight-line basis over 40 years. The results of
operations of the Dealers, including sales of $8.2 million and net income of
$139,000, have been 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

accordance with the purchase method of 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, including sales of $68.6 million and net income of $1.9
million, have been fully consolidated with those of the Company since the dates
of acquisition.

     MCQUAY DO BRASIL

     During August 1998, the Company's Lennox Global Ltd. subsidiary purchased
84% of the outstanding stock of McQuay 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

     The Company has bank lines of credit aggregating $164 million, of which $56
million was outstanding at December 31, 1998. Included in the bank lines is a
$135 million revolving credit facility. The revolving credit facility provides
for both "standby loans" and "offered rate loans." Standby loans are made
ratably by all lenders under the revolving credit facility, while offered rate
loans are, subject to the terms and conditions of the credit facility,
separately negotiated between the Company and one or more members of the lending
syndicate. Standby loans bear interest at a rate equal to either (a) the London
Interbank Offered Rate plus a margin equal to 0.150% to 0.405% depending on the
ratio of debt to total capitalization, or (b) the greater of (1) the Federal
Funds Effective Rate plus 0.5%, and (2) the Prime Rate. Offered rate loans bear
interest at a fixed rate negotiated with the lender or lenders making such
loans. Under the revolving credit facility, the Company is obligated to pay
certain fees, including (a) a quarterly facility fee to each lender under the
credit facility equal to a percentage, varying from 0.100% to 0.220% (depending
on the ratio of debt to total capitalization), of each lender's total
commitment, whether used or unused, under the revolving credit facility

and (b) certain administrative fees to the administrative agent and
documentation agent under the revolving credit facility. The revolving credit
facility will expire on July 13, 2001, unless earlier terminated pursuant to its

credit provide for restrictions with respect to additional borrowings,
maintenance of minimum working capital and payment of dividends.

     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, 1998, was a decrease of $1,891. The
decrease is a result of operating loss carryforwards which have expired.

     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,
1998, the unrecorded deferred tax liability related to the undistributed
earnings of the Company's foreign subsidiaries was insignificant.

12. EMPLOYEE BENEFIT PLANS:

     PROFIT SHARING PLANS

     The Company maintains noncontributory profit sharing plans for its 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 $12.0 million, $11.5 million, and $13.6 million in 1996,
1997, and 1998, respectively.

     401(K) PLAN

     The Company provides a 401(k) plan to substantially all eligible hourly and
salary employees of the Company, as defined. Participants may contribute up to
12% of their compensation to a 401(k) plan under Internal Revenue Code Section
401(k).

     LONG-TERM INCENTIVE PLAN

     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 2,009
shares, 7,243 shares, and 5,293 shares earned in fiscal 1995, 1996, and 1997,
respectively, were issued in 1996, 1997, and 1998, respectively. During 1998,
10,878 shares were earned and issued in the same year. Compensation expense
recognized under the Performance Plan was $1,900,000, $2,259,616, and $6,876,335
for the years ended December 31, 1996, 1997, and 1998, respectively, based on
the fair value of the shares earned.

     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.

     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
                                      F-27

     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. STOCK-BASED COMPENSATION 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):

                                                                 YEARS ENDED DECEMBER 31,

</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 248,987 shares of common stock. As of December 31, 1998, options for 165,529
shares of common stock have been granted and options for 24,892 shares have been
cancelled or repurchased. Consequently, as of December 31, 1998, there are
options for 108,350 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 1998 vest over three years. All 1998
Incentive Plan options expire after ten years.

     The Plan's status is as follows:

</TABLE>

     As of December 31, 1998, options to purchase 40,534 shares of common stock
with exercise prices ranging from $240.28 to $248.38 and options to purchase
42,409 shares of common stock with exercise prices ranging from $436.01 to
$458.82 were exercisable. The fair value of each option 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% in 1996, 1997 and 1998.

15. 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
weighted average number of shares and the number of equivalent shares assumed
outstanding, if dilutive, under the Company's stock-based compensation plans.
Diluted earnings per share are computed as follows (in thousands, except per
share data):

outstanding for the years ended December 31, 1996, 1997, and 1998, respectively,
but were not included in the diluted earnings per share calculation because the
assumed exercise of such options would have been antidilutive.

16. 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 is effective for all fiscal quarters of
fiscal years beginning after June 15, 1999. The Company does not believe that
the adoption of this pronouncement will have a significant impact on the
Company's financial statements.

the Company, as well as certain stockholders, are members of AOC Land
Investment, LLC. AOC Land Investment, LLC owns 70% of AOC Development II, LLC.
AOC Development II, LLC is building a new office building and the Company has
agreed to lease part of it for use in conjunction with the Company's corporate
headquarters. The lease will have a term of 25 years and the annual lease
payments are expected to be approximately $2.1 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.

18. SUBSEQUENT EVENTS (UNAUDITED):

     The Company is filing a registration statement for an initial public

corporate purposes, including regularly scheduled debt payments and for any
possible future acquisitions.

ITEM 20. INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     DELAWARE GENERAL CORPORATION LAW

     Section 145(a) of the Delaware General Corporation Law (the "DGCL")
provides that a corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that the person is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding if the person
acted in good faith and in a manner the person reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe the person's
conduct was unlawful.

     Section 145(b) of the DGCL provides that a corporation may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that the
person is or was a director, officer, employee or agent of the corporation, or
is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against expenses (including attorneys' fees) actually and
reasonably incurred by the person in connection with the defense or settlement
of such action or suit if the person acted in good faith and in a manner the
person reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Delaware Court
of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Delaware Court of Chancery or
such other court shall deem proper.

     Section 145(c) of the DGCL provides that to the extent that a present or
former director or officer of a corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in Section
145(a) and (b), or in defense of any claim, issue or matter therein, such person
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection therewith.

     Section 145(d) of the DGCL provides that any indemnification under Section
145(a) and (b) (unless ordered by a court) shall be made by the corporation only
as authorized in the specific case upon a determination that indemnification of
the present or former director, officer, employee or agent is proper in the
circumstances because he has met the applicable standard of conduct set forth in
Section 145(a) and (b). Such determination shall be made, with respect to a
person who is a director or officer at the time of such determination, (1) by a
majority vote of the directors who were not parties to such action, suit or
proceeding, even though less than a quorum, or (2) by a committee of such
directors designated by majority vote of such directors, even though less than a
quorum, or (3) if there are no such directors, or if such directors so direct,
by independent legal counsel in a written opinion, or (4) by the stockholders.

     Section 145(e) of the DGCL provides that expenses (including attorneys'
fees) incurred by an officer or director in defending any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an

                                      II-1
<PAGE>   105

undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that such person is not entitled to be
indemnified by the corporation as authorized in Section 145. Such expenses
(including attorneys' fees) incurred by former directors and officers or other
employees and agents may be so paid upon such terms and conditions, if any, as
the corporation deems appropriate.

     Section 145(f) of the DGCL provides that the indemnification and
advancement of expenses provided by, or granted pursuant to, Section 145 shall
not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any bylaw,
agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in such person's official capacity and as to action in another
capacity while holding such office.

     Section 145(g) of the DGCL provides that a corporation shall have the power
to purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against any liability asserted against such person and incurred by such person
in any such capacity, or arising out of such person's status as such, whether or
not the corporation would have the power to indemnify such person against such
liability under Section 145.

     Section 102(b)(7) of the DGCL provides that the liability of a director may
not be limited or eliminated for the breach of such director's duty of loyalty
to the corporation or its stockholders, for such director's intentional acts or
omissions not in good faith, for such director's concurrence in or vote for an
unlawful payment of a dividend or unlawful stock purchase or redemption or for
any improper personal benefit derived by the director from any transaction.

     RESTATED CERTIFICATE OF INCORPORATION

     Article Eighth of Lennox's restated certificate of incorporation provides
that a director of Lennox shall not be liable to Lennox or its stockholders for
monetary damages for breach of fiduciary duty as a director, except to the
extent such exemption from liability or limitation thereof is not permitted
under the DGCL as the same exists or may hereafter be amended. Any repeal or
modification of Article Eighth shall not adversely affect any right or
protection of a director of Lennox existing thereunder with respect to any act
or omission occurring prior to such repeal or modification.

     BYLAWS

     Article VI of Lennox's bylaws provides that each person who at any time
shall serve or shall have served as a director or officer of Lennox, or any
person who, while a director or officer of Lennox, is or was serving at the
request of Lennox as a director or officer of another corporation, partnership,
joint venture, trust or other enterprise, shall be entitled to (a)
indemnification and (b) the advancement of expenses incurred by such person from
Lennox as, and to the fullest extent, permitted by Section 145 of the DGCL or
any successor statutory provision, as from time to time amended. Lennox may
indemnify any other person, to the same extent and subject to the same
limitations specified in the immediately preceding sentence, by reason of the
fact that such other person is or was an employee or agent of Lennox or another
corporation, partnership, joint venture, trust or other enterprise.

     The indemnification and advancement of expenses provided by, or granted
pursuant to, Article VI shall not be deemed exclusive of any other rights to
which any person seeking indemnification or advancement of expenses may be
entitled under any bylaw of Lennox, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in such person's
official capacity and as to action in another capacity while holding such
office. All rights to indemnification under Article VI shall be deemed to be
provided by a contract between Lennox and the director, officer, employee or
agent who served in such capacity at any time while the bylaws of Lennox and
other relevant provisions of the DGCL and other applicable law, if any, are in
effect. Any repeal or modification thereof shall not affect any rights or
obligations then existing. Without limiting the provisions of Article VI, Lennox

ITEM 22. UNDERTAKINGS.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Securities Act") may be permitted to directors,
officers and controlling persons of the registrant pursuant to

                                      II-5
<PAGE>   109

the foregoing provisions, or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

     The undersigned registrant also undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

          (i) To include any prospectus required by section 10(a)(3) of the
     Securities Act;

          (ii) To reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) under the Securities Act if, in the aggregate, the
     changes in volume and price represent no more than a 20% change in the
     maximum aggregate offering price set forth in the "Calculation of
     Registration Fee" table in the effective registration statement;

          (iii) To include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

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 registration statement on Form S-1 and have issued
our report thereon dated February 18, 1999. 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 financial statements taken as a whole.
