                               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 the U.S. and Canada 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 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 OPERATING RESULTS

     For the three months ended June 30, 1999, we expect that net sales will be
approximately $591.9 million, an increase of 29.8% from $456.0 million for the
three months ended June 30, 1998. Income from operations is expected to increase
by $12.9 million, or 37.9%, to approximately $46.9 million for the three months
ended June 30, 1999, as compared to $34.0 million for the corresponding period
in 1998. We expect that net income will be approximately $23.6 million for the
three months ended June 30, 1999, an increase of 37.2% from $17.2 million for
the three months ended June 30, 1998.

     For the six months ended June 30, 1999, we expect that net sales will be
approximately $1,080.9 million, an increase of 29.4% from $835.6 million for the
six months ended June 30, 1998. Income from operations is expected to increase
by $14.8 million, or 28.5%, to approximately $66.7 million for the first six
months of this year, as compared to $51.9 million for the corresponding period
in 1998. We expect that net income will be approximately $30.2 million for the
six months ended June 30, 1999, an increase of 18.4% from $25.5 million for the
six months ended June 30, 1998.

                             The net proceeds will be used to repay a portion of
                             the amounts borrowed under our revolving credit
                             facility and term credit agreement. We will not
                             receive any proceeds from the sale of the shares of
                             common stock offered by the selling stockholders.

Proposed NYSE symbol.......  LII

     All information in this prospectus relating to the number of shares of our
common stock or options has been adjusted to reflect a 33-for-one stock split of
our common stock which occurred on July 6, 1999.

     Unless we specifically state otherwise, the information in this prospectus
does not take into account the issuance of up to 1,275,000 shares of common
stock which the underwriters have the option to purchase solely to cover
over-allotments. If the underwriters exercise their over-allotment option in
full, 45,935,740 shares of common stock will be outstanding after the offering.

     The number of shares of our common stock to be outstanding immediately
after the offering does not take into account 3,868,458 shares of our common
stock that will be issuable upon the exercise of stock options, substantially
all of which were awarded under our stock option plans. Stock options for
2,838,858 shares of common stock are currently exercisable. For more information
on our stock option plans, see "Management -- 1998 Incentive Plan."

                        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. The as adjusted amounts give
effect to this offering and the use of the net proceeds as described under "Use
of Proceeds."

(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

                                        8
<PAGE>   11

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 is 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.

                                        9
<PAGE>   12

    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.

                                       10
<PAGE>   13

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 over 70% 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.

                                       11
<PAGE>   14

     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 after the offering, 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 the offering, we will have
outstanding 44,660,740 shares of common stock. Of these shares, the shares sold
in this 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
36,160,740 shares of common stock outstanding, which will represent
approximately 81% 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.

    BECAUSE THERE HAS BEEN NO PRIOR PUBLIC MARKET FOR OUR COMMON STOCK, OUR
    STOCK PRICE MAY FLUCTUATE SIGNIFICANTLY AFTER THE OFFERING AND YOU COULD
    LOSE ALL OR PART OF YOUR INVESTMENT AS A RESULT

     Prior to the offering, there has been no public market for our common
stock. We do not know how our common stock will trade in the future. The initial
public offering price will be determined through negotiations between the
underwriters and us. You may not be able to resell your shares at or above the
initial public offering price as 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.

     You should read the "Underwriters" section for a more complete discussion
of the factors considered in determining the initial public offering price.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     Some of the statements under "Prospectus Summary," "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business," and elsewhere in this prospectus constitute
forward-looking statements. These statements relate to future events or our
future financial performance. In come cases, you can identify forward-looking
statements by terminology such as "may," "will," "should," "expects," "plans,"
"anticipates," "believes," "estimates," "predicts," "potential" or "continue" or
the negative of such terms or other comparable terminology. These statements are
only predictions. Actual events or results may differ materially. In evaluating
these statements, you should specifically consider various factors, including
the risks outlined under "Risk Factors." These factors may cause our actual
results to differ materially from any forward-looking statement.

     Although we believe that the expectations reflected in the forward-looking

                                USE OF PROCEEDS

     We estimate that our net proceeds from the sale of our common stock in the
offering, after deducting estimated expenses of $1.1 million and underwriting
discounts and commissions, will be approximately $138.4 million, or
approximately $160.4 million if the underwriters exercise their over-allotment
option in full, at an assumed initial public offering price of $18.50 per share.
We will use all of the proceeds from the offering to repay a portion of the
borrowings under our revolving credit facility and term credit agreement.
Borrowing availability under our revolving credit facility will be used:

     - to fund some of the cash portion of the purchase of additional dealers
       and for other acquisitions;

     - to provide working capital for our expanded operations;

     - to fund capital expenditures; and

     - for other general corporate purposes.

     As of July 1, 1999 approximately $120 million was outstanding under our
revolving credit facility at an average interest rate of 5.2% and approximately
$90 million was outstanding under our term credit agreement at an interest rate
of 6.0%. Borrowings under our revolving credit facility and term credit
agreement, along with cash flow from operations, were used for:

     - seasonal working capital needs;

     - the acquisitions of the hearth products companies;

     - the acquisitions of heating and air conditioning dealers in Canada;

     - certain international acquisitions, including McQuay do Brasil S.A.;

     - the acquisition of Livernois Engineering Holding Company and its licensed
       patents; and

     - expenses incurred in our Pulse inspection program.

     For more information about our revolving credit facility and term credit
agreement, see "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."

     We will not receive any proceeds from the sale of common stock offered by
the selling stockholders.

                                DIVIDEND POLICY

     We paid cash dividends of $0.26, $0.28 and $0.32 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."

                                    DILUTION

     Our net tangible book value as of March 31, 1999 was approximately $164.5
million or $4.63 per share of common stock. Net tangible book value per share
represents the amount of our total tangible assets less total liabilities,
divided by the number of shares of common stock issued and outstanding. After
giving effect to the sale of the 8,088,490 shares of common stock offered by us
at an assumed initial public offering price of $18.50 per share and the use of
the net proceeds as described under "Use of Proceeds", our pro forma net
tangible book value as of March 31, 1999 would have been $302.9 million, or
$6.94 per share. This represents an immediate increase in net tangible book
value of $2.31 per share to existing stockholders and an immediate dilution of
$11.56 per share to new investors.

     The following table illustrates this per share dilution:

                       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.

(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.

                      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,
primarily due to the performance of the commercial air conditioning business. In
the second half of 1998, we

                                       18
<PAGE>   21

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 $68 million and $86 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 July 2, 1999, we had acquired 50 dealers in Canada and two in
the U.S. for an aggregate purchase price of approximately $74 million and had
signed letters of intent to acquire nine additional Canadian dealers and 11 U.S.
dealers for an aggregate purchase price of approximately $79 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.

     THREE MONTHS ENDED MARCH 31, 1999 COMPARED TO THREE MONTHS ENDED MARCH 31,
     1998

     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 $5.0 million was due to sales from acquired heating and air conditioning
distributors. The remaining $23.7 million increase in North American residential
net sales was primarily due to an 11.6% 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

                                       20
<PAGE>   23

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 $11.4 million. North American commercial
refrigeration sales increased $2.4 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 $4.9 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

                                       21
<PAGE>   24

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, $1.3 million was due
to the incurrence of $75 million in additional long-term borrowings in April
1998 and $2.7 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

                                       22
<PAGE>   25

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

                                       23
<PAGE>   26

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 $(17.8) million during 1997. International income (loss) from
operations was $(2.1) million during 1998 and $(17.4) 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, $1.6 million was due to the consolidation of
Ets. Brancher for the full year and the remainder was due to less interest
income in 1998.

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

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

                                       24
<PAGE>   27


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, 49.3% 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 $(17.8) million during 1997 as
compared to $98.0 million during 1996. International income from operations was
$(17.4) 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.

                                       25
<PAGE>   28

     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, stock and debt. As of
July 2, 1999, we had acquired 50 dealers in Canada and two in the U.S. for an
aggregate purchase price of approximately $74 million and had signed letters of
intent to acquire nine additional Canadian dealers and 11 U.S. dealers for an
aggregate purchase price of approximately $79 million. On June 25, 1999, we
filed a shelf registration statement for $100 million of our common stock to use
in connection with acquisitions.

     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
650,430 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 $29.09 per
share for five consecutive days from the period from June 1999 to June 2000,
then we are obligated to pay the former

                                       26
<PAGE>   29

owners of Kirby the difference between the trading price for the last five days
of this period and $29.09 for 577,500 of the shares of common stock.

     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 a portion
of the net proceeds from this offering.

     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 this 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 have entered into a new $300 million revolving credit facility with a
syndicate of banks led by Chase Bank of Texas, National Association, as
administrative agent, Wachovia Bank, N.A., as syndication agent, and The Bank of
Nova Scotia, as documentation agent, to take effect upon completion of this
offering. It is a requirement that we receive not less than $140 million in net
proceeds from this offering before the new revolving credit facility will go
into effect and we can make borrowings under this facility. This new facility is
designed to replace our existing revolving credit facility and term credit
agreement. However, in the event that we do not receive at least $140 million in
net proceeds from this offering, we will maintain our existing credit facility.
The new credit facility has restrictive covenants and maintenance tests
identical to those in our existing revolving credit facility and notes, plus two
additional financial covenants. First, the ratio of total funded debt to
earnings before interest, taxes, depreciation and amortization, hereinafter
referred to as "EBITDA," cannot exceed 3.0 based upon a rolling four quarter
basis. Second, the ratio of EBITDA less capital expenditures to interest expense
should be greater than 3.0 based on a rolling four quarter basis. Pursuant to
the terms of the notes, we will be required to add these additional financial
covenants to the notes. Borrowings under this new credit facility will bear
interest, at our option, at a rate equal to either (a) the greater of the
administrative agent's prime rate or the federal funds rate plus 0.5% or (b) the
London Interbank Offered Rate plus a margin equal to 0.5% to 1.125%, depending
upon our ratio of total funded debt to EBITDA. We will pay a commitment fee
equal to 0.15% to 0.30% of the unused commitment, depending upon the ratio of
total funded debt to EBITDA. This new credit facility will have a term of five
years.



     We are currently negotiating an agreement with The Prudential Insurance
Company of America or its affiliates which, if entered into, will allow us to
borrow up to $100 million in the form of senior notes from time to time within
the first three years of the agreement. We expect that the minimum amount of
notes that we could draw at any one time would be $10 million and that the
maturity and interest rate would be selected from alternatives provided by
Prudential at the time the notes are issued, up to a maximum maturity of 15
years. We expect that the master shelf agreement will have customary covenants
and that they will be substantially similar to those contained in our
outstanding series of notes.


     We believe that cash flow from operations, as well as the net proceeds from
the 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):

11.10% promissory notes.................................    7,135       7,300      9.00
</TABLE>

     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

                                       29
<PAGE>   32

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 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.
                                       30
<PAGE>   33

     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 $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 and air conditioning dealers
in the U.S. and Canada allows us to participate in the retail sale and service
of
                                       32
<PAGE>   35

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. In May 1999, we entered into a letter of intent to
acquire essentially all of the assets of the air conditioning and heating
division of The Ducane Company, based in South Carolina, for approximately $45
million. This acquisition, if completed, will give us additional capacity to
manufacture heating and air conditioning products. 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

                                       33
<PAGE>   36

and warm air furnaces produced in 1997 for the U.S. market were approximately
$5.5 billion, reflecting a 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.

                                       34
<PAGE>   37

     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

                                       35
<PAGE>   38

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 $127 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.

                                       36

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
July 2, 1999 we had acquired 50 dealers in Canada and two in the U.S. for an
aggregate purchase price of approximately $74 million and had signed letters of
intent to acquire nine additional Canadian and 11 U.S. dealers for an aggregate
purchase price of approximately $79 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 July 2, 1999, over 1,200 dealers in the U.S. and Canada had
joined 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.

                                       37
<PAGE>   40

     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.

     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 an 84% 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.

                                       40
<PAGE>   43

     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.

                                       41

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 $33.3 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.

                                       42
<PAGE>   45

     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
                                       43
<PAGE>   46

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.

                                       45
<PAGE>   48

     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

                                       46
<PAGE>   49

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 would be required to complete the remediation. Through soil and
groundwater sampling, usually obtained during site acquisition due diligence, we
are aware of contamination at some of our other facilities. Based on the levels
of the contaminants detected, however, we do not believe we are required to
remediate the contamination at these facilities under existing environmental
laws. Nonetheless, it is possible that we may be required to conduct remediation
at these facilities in the future. Also, it is possible that third parties may
file property damage or personal injury claims against us related to this
contamination, particularly if the contamination on our property has migrated
offsite.


     During environmental due diligence for a plant we acquired in 1998 in
Czechoslovakia, we learned of soil and groundwater contamination at the site.
The source of the contamination is not known and it is not known at this time
whether the applicable governmental authority will require us to remediate the
contamination. If remediation is required, a preliminary estimate of remediation
costs prepared in 1995 is $114,000. Additional evaluation would need to be
performed to refine this estimate and it is possible that the actual cost to
remediate the plant would significantly exceed this preliminary estimate.


     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. In May 1999,
we received a settlement offer from the Gurley-Related Sites Group, a group of
potentially responsible parties for two related Superfund sites in
Arkansas -- the South 8th Street Landfill and the Gurley Pit Sites -- to settle
our potential liability at those sites for $10,500. Although we accepted the
settlement offer and paid the settlement amount, under the terms of the
settlement agreement, there is the possibility for additional liability in the
event the Gurley-Related Sites Group is not successful in its effort to finalize
its settlement in principle with the EPA and the Arkansas Department of
Pollution Control and Technology. In the event additional liability should
arise, however, we do not expect it to be material. 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.

EXECUTIVE COMPENSATION

     The following table sets forth information on compensation earned in 1998
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.

to the named executive officers in 1998.

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.

                                       55
<PAGE>   58

     The 1998 incentive plan provides for awards to be made in respect of a
maximum of 4,603,500 shares of our common stock, of which 3,943,500 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
165,000 shares of common stock, stock awards for more than 165,000 shares of
common stock or cash awards in excess of $5,000,000. 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,

                                       56
<PAGE>   59

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
16,500 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

                                       57
<PAGE>   60

     - 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 --

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

                                       59
<PAGE>   62

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.

                                       60
<PAGE>   63

     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;

                                       61
<PAGE>   64

     - 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 AND SELLING STOCKHOLDERS

     The following table contains information regarding the beneficial ownership
of our common stock as of May 31, 1999 and as adjusted to reflect the offering
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;

     - all executive officers and directors as a group; and

     - each selling stockholder.

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 35,920,104 shares of common stock
outstanding as of May 31, 1999 and 44,008,594 shares of common stock outstanding
after the completion of the offering. As of May 31, 1999, we had approximately
265 record 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 1,814,439 shares of
common stock. We will not enter into these type of agreements following
completion of the offering.

     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. Of the
200,000,000 shares of common stock authorized, 8,500,000 are being offered in
the offering, or 9,775,000 shares if the underwriters' over-allotment option is
exercised in full, and 4,603,500 shares have been reserved for issuance under
our 1998 incentive plan. See "Management -- 1998 Incentive Plan" for a
description of the 1998 incentive plan. 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

                                       65
<PAGE>   68

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.

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

                                       66
<PAGE>   69

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;

     - 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

                                       67
<PAGE>   70

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 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

                                       68
<PAGE>   71

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 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;

                                       69
<PAGE>   72

     - 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

     - 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

                                       70
<PAGE>   73

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 our certificate of incorporation, including those provisions
discussed in this section. In addition, the 80% vote described in the prior
sentence shall not be required for any alteration, amendment, adoption of
inconsistent provision or repeal of the "fair price" provision discussed under
"-- Fair Price Provision" above which is recommended to the stockholders by
two-thirds of the continuing directors of Lennox and such alteration, amendment,
adoption of inconsistent provision or repeal shall require the vote, if any,
required under the applicable provisions of the Delaware General Corporation Law
and our certificate of incorporation. In addition, our certificate of
incorporation provides that stockholders may only adopt, amend or repeal our
bylaws by the affirmative vote of holders of not less than 80% of our voting
stock, voting together as a single class. Our bylaws may be amended by our board
of directors.

RIGHTS TO PURCHASE SECURITIES AND OTHER PROPERTY

     Our certificate of incorporation authorizes the board of directors to
create and issue rights, warrants and options entitling the holders of them to
purchase from us shares of any class or classes of our capital stock or other
securities or property upon such terms and conditions as the board of directors
may deem advisable.

LISTING

     Our common stock has been approved for listing on the New York Stock
Exchange under the trading symbol "LII," subject to official notice of issuance.

TRANSFER AGENT AND REGISTRAR

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

                                       71
<PAGE>   74

                        SHARES ELIGIBLE FOR FUTURE SALE

     Prior to the offering, there has been no public market for our common
stock. Future sales of substantial amounts of common stock in the public market
could adversely affect prevailing market prices.

     Upon completion of the offering, we will have 44,660,740 shares of common
stock issued and outstanding, or 45,935,740 shares if the underwriters'
over-allotment option is exercised in full. Of these shares, the 8,500,000
shares of common stock to be sold in the offering will be 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, will be subject to the resale
limitations of Rule 144. The remaining 36,160,740 shares of common stock
outstanding will be "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. We, our directors and executive officers, the selling stockholders
and a number of other stockholders have agreed, subject to certain exceptions,
not to sell any common stock for a period of 180 days from the date of this
prospectus without the prior written consent of Morgan Stanley & Co.
Incorporated. See "Underwriters" for a discussion of these prohibitions.

         MATERIAL FEDERAL INCOME TAX CONSEQUENCES FOR NON-U.S. HOLDERS

     The following is a summary of the material U.S. federal income and estate
tax consequences expected to result under current law from the purchase,
ownership and taxable disposition of common stock by a Non-U.S. Holder. For this
purpose, a "Non-U.S. Holder" is defined as a person or entity other than:

          (a) a citizen or resident of the U.S.;

          (b) a corporation, partnership or other entity created or organized in
     or under the laws of the U.S. or of any state thereof;

          (c) an estate, the income of which is subject to U.S. federal income
     taxation regardless of its source; or

          (d) a trust whose administration is subject to the primary supervision
     of a U.S. court and which has one or more U.S. persons who have the
     authority to control all substantial decisions of the trust.

     This summary deals only with purchasers of common stock who hold common
stock as capital assets and does not address all of the U.S. federal income and
estate tax considerations that may be relevant to a Non-U.S. Holder in light of
its particular circumstances or to Non-U.S. Holders that may be subject to
special treatment under U.S. federal income tax laws, such as insurance
companies, tax-exempt organizations, financial institutions, brokers, dealers in
securities, regulated investment companies, common trust funds, or persons that
hold common stock as part of a hedge, conversion or constructive sale
transaction, straddle or other risk reduction transaction. Furthermore, this
summary does not discuss any aspects of state, local or foreign taxation. This
summary is based on current provisions of the Internal Revenue Code of 1986,
Treasury regulations, judicial opinions, published positions of the U.S.
Internal Revenue Service and other applicable authorities, all of which are
subject to change, possibly with retroactive effect. Each prospective purchaser
of common stock is advised to consult its tax advisor with respect to the tax
consequences of acquiring, holding and disposing of common stock.

     DIVIDENDS

     Dividends paid to a Non-U.S. Holder of common stock generally will be
subject to withholding of U.S. federal income tax at a 30 percent rate or a
lower rate that is specified by an applicable income tax treaty. However, if
dividends are effectively connected with the conduct of a trade or business by
the Non-U.S. Holder in the U.S. they may be taxed at ordinary U.S. federal
income tax rates and will not be subject to the withholding tax described above.
In order for this treatment to apply, the Non-U.S. Holder must provide the
dividend payor with proper documentation, consisting generally of I.R.S. Form
4224 and, if an income tax treaty is applicable, must maintain a U.S. permanent
establishment to which the dividends are attributable. If the Non-U.S. Holder is
a corporation, such effectively connected income may also be subject to an
additional "branch profits tax" which is imposed, under certain circumstances,
at a rate of 30% or a lower rate that is specified by an applicable treaty of
the Non-U.S. corporation's "effectively connected earnings and profits," subject
to certain adjustments.

     SALE OR DISPOSITION OF COMMON STOCK

     A Non-U.S. Holder generally will not be subject to U.S. federal income tax
in respect of any gain recognized on the sale or other taxable disposition of
common stock unless:

     - the gain is effectively connected with a trade or business of the
       Non-U.S. Holder in the U.S.;

     - in the case of a Non-U.S. Holder who is an individual and holds the
       common stock as a capital asset, the holder is present in the U.S. for
       183 or more days in the taxable year of the disposition and either (a)
       the individual has a "tax home" for U.S. federal income tax purposes in
       the U.S. or (b) the gain is attributable to an office or other fixed
       place of business maintained by the individual in the U.S.;

     - the Non-U.S. Holder is subject to tax pursuant to the provisions of U.S.
       federal income tax law applicable to certain U.S. expatriates; or

                                       73
<PAGE>   76

     - Lennox is or has been during certain periods preceding the disposition a
       U.S. real property holding corporation and either (a) the common stock
       ceases to be "regularly traded on an established securities market" for
       U.S. federal income tax purposes or (b) the Non-U.S. Holder has held,
       directly or indirectly, at any time during the five-year period ending on
       the date of disposition, more than 5 percent of all of Lennox's
       outstanding common stock. Lennox is not, and does not anticipate
       becoming, a U.S. real property holding corporation.

     BACKUP WITHHOLDING AND INFORMATION REPORTING

     Lennox must report annually to the IRS and to each Non-U.S. Holder the
amount of dividends paid to such holder and the amount, if any, of tax withheld
with respect to such dividends. This information may also be made available to
the tax authorities in the Non-U.S. Holder's country of residence.

     U.S. backup withholding is a withholding tax imposed at the rate of 31% on
certain payments to persons that fail to furnish certain information under the
U.S. information reporting requirements. Generally it will not apply to
dividends paid to Non-U.S. Holders if such dividends are subject to the 30% or
lower treaty rate withholding discussed above. In the case of dividends which
are not described in the preceding sentence, backup withholding would still not
apply (a) under current law, if such dividends are paid before January 1, 2001
to a Non-U.S. Holder at an address outside the U.S. or (b) under recently
promulgated final U.S. Treasury regulations which are to become effective as of
January 1, 2001, if certain certification procedures or documentation
requirements are satisfied.

     Upon the sale or other taxable disposition of common stock by a Non-U.S.
Holder to or through a U.S. office of a broker, the broker must backup withhold
at a rate of 31 percent and report the sale to the IRS, unless the holder
certifies its non-U.S. status under penalties of perjury or otherwise
establishes an exemption. Upon the sale or other taxable disposition of common
stock by a Non-U.S. Holder to or through the foreign office of a U.S. broker, or
a foreign broker with certain types of relationships to the U.S., the broker
must report the sale to the IRS unless the broker has documentary evidence in
its files that the seller is a Non-U.S. Holder and certain other conditions are
met, or the holder otherwise establishes an exemption, but, prior to January 1,
2001, the broker need not withhold. A sale or other taxable disposition of
common stock by a Non-U.S. Holder to or through the foreign office of a foreign
broker that does not have certain types of relationships to the U.S. is
generally not subject to either information reporting or backup withholding.

     Backup withholding is not an additional U.S. federal income tax. Amounts
withheld under the backup withholding rules are generally allowable as a refund
or credit against such Non-U.S. Holder's U.S. federal income tax liability, if
any, provided that the required information is furnished to the IRS.

     FEDERAL ESTATE TAXES

     Common stock owned or treated as owned by an individual who is not a
citizen or resident for U.S. federal estate tax purposes of the U.S. at the time
of death will be included in such individual's gross estate for U.S. federal
estate tax purposes, unless an applicable estate tax treaty provides otherwise.

</TABLE>

     The U.S. underwriters and the international underwriters, and the U.S.
representatives and the international representatives, are collectively referred
to as the "underwriters" and the "representatives", respectively. The
underwriters are offering the shares of common stock subject to their acceptance
of the shares from us and the selling stockholders and subject to prior sale.
The underwriting agreement provides that the obligations of the several
underwriters to pay for and accept delivery of the shares of common stock
offered

                                       75
<PAGE>   78

by this prospectus are subject to the approval of certain legal matters by their
counsel and to certain other conditions. The underwriters are obligated to take
and pay for all of the shares of common stock offered by this prospectus, other
than those covered by the U.S. underwriters' over-allotment option described
below, if any such shares are taken.

     In the agreement between U.S. and international underwriters, each U.S.
underwriter has represented and agreed that:

     - it is not purchasing any shares for the account of anyone other than a
       U.S. or Canadian person; and

     - it has not offered or sold, and will not offer or sell, directly or
       indirectly, any shares or distribute any prospectus relating to the
       shares outside the U.S. or Canada or to anyone other than a U.S. or
       Canadian person.

     In the agreement between U.S. and international underwriters, each
international underwriter has represented and agreed that:

     - it is not purchasing any shares for the account of any U.S. or Canadian
       person; and

     - it has not offered or sold, and will not offer or sell, any shares or
       distribute any prospectus relating to the shares in the U.S. or Canada or
       to any U.S. or Canadian person.

     For any underwriter that is both a U.S. underwriter and an international
underwriter, the representations and agreements made by it in its capacity as a
U.S. underwriter apply only to it in its capacity as a U.S. underwriter and made
by it in its capacity as an international underwriter apply only to it in its
capacity as an international underwriter. The limitations described above do not
apply to stabilization transactions or to certain other transactions specified
in the agreement between U.S. and international underwriters. As used in this
section, "U.S. or Canadian person" means any national or resident of the U.S. or
Canada, or any corporation, pension, profit-sharing or other trust or other
entity organized under the laws of the U.S. or Canada, or of any political
subdivision of the U.S. or Canada (other than a branch located outside the U.S.
and Canada of any U.S. or Canadian person). U.S. or Canadian person includes any
U.S. or Canadian branch of a person who is otherwise not a U.S. or Canadian
person.

     In the agreement between U.S. and international underwriters, sales may be
made between U.S. underwriters and international underwriters of any number of
shares as may be mutually agreed. The per share price of any shares sold by the
underwriters shall be the public offering price listed on the cover page of this
prospectus, in U.S. dollars, less an amount not greater than the per share
amount of the concession to dealers described below.

     In the agreement between U.S. and international underwriters, each U.S.
underwriter has represented that it has not offered or sold, and has agreed not
to offer or sell, any shares, directly or indirectly, in any province or
territory of Canada or to, or for the benefit of, any resident of any province
or territory of Canada in contravention of the securities laws of Canada. Each
U.S. underwriter has represented that any offer or sale of shares in Canada will
be made only pursuant to an exemption from the requirement to file a prospectus
in the province or territory of Canada in which the offer or sale is made. Each
U.S. underwriter has further agreed to send to any dealer who purchases from it
any of the shares a notice stating that, by purchasing such shares, the dealer
represents and agrees that it has not offered or sold, and will not offer or
sell, directly or indirectly, any shares in any province or territory of Canada
or to, or for the benefit of, any resident of any province or territory of
Canada in contravention of the securities laws thereof and that any offer or
sale of shares in Canada will be made only pursuant to an exemption from the
requirement to file a prospectus in the province or territory of Canada in which
the offer or sale is made. Each dealer will deliver to any other dealer to whom
it sells any of the shares a notice containing substantially the same Canadian
restrictions.

     In the agreement between U.S. and international underwriters, each
international underwriter has represented and agreed that:

     - it has not offered or sold and, prior to the date six months after the
       closing date for the sale of the shares to the international
       underwriters, will not offer or sell, any shares to persons in the United

                                       76
<PAGE>   79

       Kingdom except to persons whose ordinary activities involve them in
       acquiring, holding, managing or disposing of investments, as principal or
       agent, for the purposes of their businesses or otherwise in circumstances
       which have not resulted and will not result in an offer to the public in
       the United Kingdom within the meaning of the Public Offers of Securities
       Regulations 1995;

     - it has complied and will comply with all applicable provisions of the
       Financial Services Act 1986 with respect to anything done by it in
       relation to the shares in, from or otherwise involving the United
       Kingdom; and

     - it has and will distribute any document relating to the shares in the
       United Kingdom only to a person who is of a kind described in Article
       11(3) of the Financial Services Act 1986 (Investment Advertisements)
       (Exemptions) Order 1996 (as amended) or is a person to whom such document
       may otherwise lawfully be issued or passed on.

     In the agreement between U.S. and international underwriters, each
international underwriter has further represented that it has not offered or
sold, and has agreed not to offer or sell in Japan or to or for the account of
any resident of Japan, any of the shares. This limitation does not apply to
offers or sales to Japanese international underwriters or dealers and to offers
and sales pursuant to any exemption from the registration requirements of the
Securities and Exchange Law and otherwise in compliance with applicable
provisions of Japanese law. Each international underwriter has further agreed to
send to any dealer who purchases from it any of the shares a notice stating in
substance that, by purchasing the shares, the dealer agrees that any offer or
sales of shares in Japan will be made only to Japanese international
underwriters or dealers or under an exemption from the registration requirements
of the Securities and Exchange Law and otherwise in compliance with applicable
provisions of Japanese law. Each dealer will send to any other dealer to whom it
sells any shares a notice containing substantially the same Japanese selling
restrictions.

     The underwriters initially propose to offer part of the shares of common
stock directly to the public at the public offering price listed on the cover
page of this prospectus and part to certain dealers at a price that represents a
concession not in excess of $     a share under the public offering price. Any
underwriter may allow, and such dealers may reallow, a concession not in excess
of $     a share to other underwriters or to certain dealers. After the initial
offering of the shares of common stock, the offering price and other selling
terms may from time to time be varied by the representatives.

     Lennox has granted to the U.S. underwriters an option, exercisable for 30
days from the date of this prospectus, to purchase up to an aggregate of
1,275,000 additional shares of common stock at the public offering price listed
on the cover page of this prospectus, less underwriting discounts and
commissions. The U.S. underwriters may exercise this option solely for the
purpose of covering over-allotments, if any, made in connection with the
offering of the shares of common stock offered by this prospectus. To the extent
the option is exercised, each U.S. underwriter will become obligated, subject to
certain conditions, to purchase about the same percentage of the additional
shares of common stock as the number listed next to such U.S. underwriter's name
in the preceding table bears to the total number of shares of common stock
listed next to the names of all U.S. underwriters in the preceding table. If the
U.S. underwriters' option is exercised in full, the total price to the public
would be $     , the total underwriters' discounts and commissions would be
$     and total proceeds to Lennox would be $     .

     At the request of Lennox, the underwriters have reserved for sale, at the
initial public offering price, up to 425,000 shares for directors, officers,
employees, business associates and related persons of Lennox. The number of
shares of common stock available for sale to the general public will be reduced
to the extent these persons purchase reserved shares. Any reserved shares which
are not so purchased will be offered by the underwriters to the general public
on the same basis as the other shares offered under this prospectus.

     The underwriters have informed Lennox that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
common stock offered by them.

     Our common stock has been approved for listing on the New York Stock
Exchange under the trading symbol "LII," subject to official notice of issuance.

     Each of Lennox and the directors, executive officers, the selling
stockholders and certain other stockholders of Lennox has agreed that, without
the prior written consent of Morgan Stanley & Co. Incorporated on behalf of the
underwriters, it will not, during the period ending 180 days after the date of
this prospectus:

     - 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:

     - the sale of shares to the underwriters;

     - 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 the 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 the offering;

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

     - the issuance of up to 5.4 million 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.

     In order to facilitate the offering of the common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common stock. Specifically, the underwriters may over-allot in
connection with the offering, creating a short position in the common stock for
their own account. In addition, to cover over-allotments or to stabilize the
price of the common stock, the underwriters may bid for, and purchase, shares of
common stock in the open market. Finally, the underwriting syndicate may reclaim
selling concessions allowed to an underwriter or a dealer for distributing the
common stock in the offering, if the syndicate repurchases previously
distributed common stock in transactions to cover syndicate short positions, in
stabilization transactions or otherwise. The underwriters have reserved the
right to reclaim selling concessions in order to encourage underwriters and
dealers to distribute the common stock for investment, rather than for
short-term profit taking. Increasing the proportion of the offering held for
investment may reduce the supply of common stock available for short-term
trading. Any of these activities may stabilize or maintain the market price of
the common stock above independent market levels. The underwriters are not
required to engage in these activities, and may end any of these activities at
any time.

     Lennox, the selling stockholders and the underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act of 1933.

     An affiliate of Credit Suisse First Boston Corporation was a participant
bank in Lennox's revolving credit facility which expired in June 1998. Such
affiliate currently has issued approximately $20 million in letters of credit on
behalf of Lennox, all but $1 million of which expired in December 1998. Such
affiliate has received customary banking fees for such services. In addition,
Warburg Dillon Read LLC has provided certain

                                       78

investment banking services and has acted as placement agent for Lennox's
private placements of debt securities in 1993 and 1998, for which services they
received customary fees in connection therewith.

     PRICING OF THE OFFERING

     Prior to this offering, there has been no public market for the common
stock. The initial public offering price will be determined by negotiations
between Lennox and the U.S. representatives. Among the factors to be considered
in determining the initial public offering price will be the future prospects of
Lennox and its industry in general, sales, earnings and certain other financial
operating information of Lennox in recent periods, and the price-earnings
ratios, price-sales ratios, market prices of securities and certain financial
and operating information of companies engaged in activities similar to those of
Lennox. The estimated initial public offering price range set forth on the cover
page of this prospectus is subject to change as a result of market conditions
and other factors.


     Pursuant to the repayment of our revolving credit facility and term credit
agreement,        will receive an amount greater than 10% of the net proceeds of
the sale of our common stock.        is an affiliate of        , which is a
member of the National Association of Securities Dealers. Accordingly, the
underwriting arrangements related to our sale of common stock must comply with
Rule 2710(c)(8) and Rule 2720(c)(3) of the Conduct Rules of the National
Association of Securities Dealers. The rules provide that when a National
Association of Securities Dealer member is to receive an amount greater than 10%
of the net proceeds of an offering, the initial public offering price can be no
higher than that recommended by a "qualified independent underwriter" that meets
the standards outlined in the rule. To comply with this requirement, Morgan
Stanley & Co. Incorporated will serve as a qualified independent underwriter and
will recommend a price in compliance with the requirements of Rule 2720. In
connection with our offering of common stock, Morgan Stanley & Co. Incorporated,
in its role as qualified independent underwriter, has performed due diligence
and investigations and reviewed and participated in the preparation of this
prospectus and the registration statement.

                                  (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

8. SUBSEQUENT EVENTS

     The Company experienced a work stoppage at the Bellevue, Ohio factory for
three weeks in May 1999. This factory manufactures the Company's "Armstrong Air"
brand of residential heating and air conditioning products for the North
American market. 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.

     Subsequent to March 31, 1999, the Company acquired Livernois Engineering
Holding Company and its licensed patents for approximately $21 million.
Livernois produces heat transfer manufacturing equipment for the HVACR and
automotive industries.

     Between April 1, 1999, and July 2, 1999, the Company had acquired 14
dealers in Canada and two dealers in the U.S. for an aggregate purchase price of
approximately $17 million in cash. The Company also signed letters of intent to
acquire nine additional Canadian dealers and 11 U.S. dealers for an aggregate
purchase price of approximately $79 million.

     The Company has entered into an agreement to buy the remaining 30% interest
in Ets. Brancher for 102.5 million French francs (approximately $17 million) on
March 31, 2000.

     In June 1999, the Company acquired James N. Kirby Pty. Ltd., an Australian
company that participates in the commercial refrigeration and heat transfer
markets in Australia, for approximately $67 million.

     In July 1999, the Company declared a 33-for-one common stock split.
Accordingly, all information related to the number of shares of the Company's
common stock and options has been adjusted to reflect the stock split.


     In July 1999, the Company entered into a new $300 million revolving credit
facility with a syndicate of banks. It is a requirement that the Company receive
not less than $140 million in net proceeds from an initial public offering of
common stock before the new revolving credit facility will go into effect.
Borrowings under this new credit facility will bear interest, at the Company's
option, at a rate equal to either (a) the greater of the administrative agent's
prime rate or the federal funds rate plus 0.5% or (b) the London Interbank
Offered Rate plus a margin equal to 0.5% to 1.125%. Additionally, the Company is
obligated to pay a commitment fee equal to 0.15% to 0.30% of the unused
commitment. The new credit facility will have a term of 5 years.

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

     We have audited the accompanying consolidated balance sheets of Lennox

1997 and 1998, and the related consolidated statements of income, stockholders'
equity, and cash flows for each of the three years in the period ended December
31, 1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Lennox International Inc.
and Subsidiaries as of December 31, 1997 and 1998, and the results of their
operations and their cash flows for each of the three years in the period ended

                   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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     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

(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
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
(631,389 shares). The acquisition was accounted for in accordance with the
purchase method of accounting. Accordingly, the purchase price has been
allocated to the assets and liabilities based upon their estimated fair values
at the date of acquisition. As

a result, the Company recorded additional goodwill of approximately $6.4
million, which is being amortized on a straight-line basis over a 30-year
period.

     The Company has entered into an agreement to acquire the remaining 30%
interest in Ets. Brancher S.A. 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
Co. and all of the outstanding stock of Marco Mfg. Inc. and Pyro Industries Inc.
The aggregate purchase price for these acquisitions was $102.9 million, of which
$99.1 million was in cash and $3.8 million was in the form of a note payable.
These acquisitions were accounted for in 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,

     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 terms and
conditions. The unsecured promissory note agreements and lines of 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.

     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):

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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

     Under the 1998 Incentive Plan, the Company is authorized to issue options
for 8,216,571 shares of common stock. As of December 31, 1998, options for
5,462,457 shares of common stock have been granted and options for 821,436
shares have been cancelled or repurchased. Consequently, as of December 31,
1998, there are options for 3,575,550 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 (in thousands, except per share data):

stock with exercise prices ranging from $7.28 to $7.53 and options to purchase
1,399,497 shares of common stock with exercise prices ranging from $13.21 to

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 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.

17. RELATED PARTY TRANSACTIONS

     John W. Norris, Jr., the Company's Chairman and Chief Executive Officer,
and David H. Anderson, Richard W. Booth, David V. Brown, Loraine B. Millman,
Robert W. Norris and Lynn B. Storey, directors of 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
offering of its common stock, the proceeds of which will be used to repay a
portion of the borrowings under the Company's revolving credit facility and term
credit agreement.

ITEM 14. 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.

                                      II-1
<PAGE>   119

     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 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

                                      II-2
<PAGE>   120

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
is authorized from time to time, without further action by the stockholders of
Lennox, to enter into agreements with any director or officer of Lennox
providing such rights of indemnification as Lennox may deem appropriate, up to
the maximum extent permitted by law. Any agreement entered into by Lennox with a
director may be authorized by the other directors, and such authorization shall
not be invalid on the basis that similar agreements may have been or may
thereafter be entered into with other directors.

     Lennox may purchase and maintain insurance on behalf of any person who is
or was a director, officer, employee or agent of Lennox, or is or was serving at
the request of Lennox 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 Lennox
would have the power to indemnify such person against such liability under the
applicable provisions of Article VI or the DGCL.

     UNDERWRITING AGREEMENT

     The Underwriting Agreement, the form of which is filed as Exhibit 1.1 to
this Registration Statement, provides for the indemnification of the directors
and officers of Lennox against certain liabilities, including liabilities
arising under the Securities Act of 1933, as amended (the "Securities Act").

     The above discussion of the restated certificate, bylaws and Underwriting
Agreement, and Section 145 of the DGCL is not intended to be exhaustive and is
respectively qualified in its entirety by the restated certificate, bylaws,
Underwriting Agreement and such statute.

ITEM 17. UNDERTAKINGS.

     The undersigned Registrant hereby undertakes to provide to the underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
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 that:

          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this registration statement in reliance upon Rule 430A and contained in the
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of the
     registration statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and this offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

                    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.

Dear Ladies and Gentlemen:

         Lennox International Inc., a Delaware corporation (the "COMPANY"),
proposes to issue and sell to the several Underwriters (as defined below)
hereto, and certain stockholders of the Company (the "SELLING STOCKHOLDERS")
named in Schedule I hereto severally propose to sell to the several
Underwriters, an aggregate of 8,500,000 shares of the Common Stock, par value
$.01 per share, of the Company (the "FIRM SHARES"), of which 8,088,490 shares
are to be issued and sold by the Company and 411,510 shares are to be sold by
the Selling Stockholders, each Selling Stockholder selling the amount set forth
opposite such Selling Stockholder's name in Schedule I hereto.

         It is understood that, subject to the conditions hereinafter stated,
6,800,000 Firm Shares (the "U.S. FIRM SHARES") will be sold to the several U.S.
Underwriters named in Schedule II hereto (the "U.S. UNDERWRITERS") in connection
with the offering and sale of such U.S. Firm Shares in the United States (as
defined below) and Canada to United States or Canadian Persons (as defined
below), and 1,700,000 Firm Shares (the "INTERNATIONAL SHARES") will be sold to
the several International Underwriters named in Schedule III hereto (the
"INTERNATIONAL UNDERWRITERS") in connection with the offering and sale of such

United States and Canada to persons other than United States or Canadian
Persons. Morgan Stanley & Co. Incorporated, Credit Suisse First Boston
Corporation and Warburg Dillon Read LLC, a subsidiary of UBS AG, shall act as
representatives (the "U.S. REPRESENTATIVES") of the several U.S. Underwriters,
and Morgan Stanley & Co. International Limited, Credit Suisse First Boston
(Europe) Limited and UBS AG, acting through its division Warburg Dillon Read,
shall act as representatives (the "INTERNATIONAL REPRESENTATIVES") of the
several International Underwriters. The U.S. Underwriters and the International
Underwriters are hereinafter collectively referred to as the "UNDERWRITERS".

         "UNITED STATES OR CANADIAN PERSON" shall mean any national or resident
of the United States or Canada, or any corporation, pension, profit-sharing or
other trust or other entity organized under the laws of the United States or
Canada or of any political subdivision thereof (other than a branch located
outside the United States and Canada of any United States or Canadian Person),
and shall include any United States or Canadian branch of a person who is
otherwise not a United States or Canadian Person. "UNITED STATES" shall mean the
United States of America, its territories, its possessions and all areas subject
to its jurisdiction.

         The Company also proposes to issue and sell to the several U.S.
Underwriters not more than an additional 1,275,000 shares of its Common Stock,
par value $.01 per share (the "ADDITIONAL SHARES") if and to the extent that the
U.S. Representatives shall have determined to exercise, on behalf of the U.S.
Underwriters, the right to purchase such shares of common stock granted to the
U.S. Underwriters in Section 3 hereof. The Firm Shares and the Additional Shares
are hereinafter collectively referred to as the "SHARES". The shares of Common
Stock, par value $.01 per share, of the Company to be outstanding after giving
effect to the sales contemplated hereby are hereinafter referred to as the
"COMMON STOCK". The Company and the Selling Stockholders are hereinafter
sometimes collectively referred to as the "SELLERS".

         The Company has filed with the Securities and Exchange Commission (the
"COMMISSION") a registration statement relating to the Shares. The registration
statement contains two prospectuses to be used in connection with the offering
and sale of the Shares: the U.S. prospectus, to be used in connection with the
offering and sale of Shares in the United States and Canada to United States or
Canadian Persons, and the international prospectus, to be used in connection
with the offering and sale of Shares outside the United States and Canada to
persons other than United States or Canadian Persons. The international
prospectus is identical to the U.S. prospectus except for the outside front
cover page. The registration statement as amended at the time it becomes
effective, including the information (if any) deemed to be part of the
registration statement at the time of effectiveness pursuant to Rule 430A under
the Securities Act of 1933, as amended (the "SECURITIES ACT"), is hereinafter
referred to as the "REGISTRATION STATEMENT"; the U.S. prospectus and the
international prospectus in the respective forms first used to confirm sales of
Shares are hereinafter referred to as the "PROSPECTUS". If the Company has filed
an abbreviated registration statement to register additional shares of Common
Stock pursuant to Rule 462(b) under the Securities Act (the "RULE 462
REGISTRATION STATEMENT"), then


                                       -2-

any reference herein to the term "REGISTRATION STATEMENT" shall be deemed to
include such Rule 462 Registration Statement.

         As part of the offering contemplated by this Agreement, Morgan Stanley
& Co. Incorporated ("MORGAN STANLEY") and certain other Underwriters have agreed
to reserve out of the Shares set forth opposite their names on Schedule II to
this Agreement up to 425,000 shares for sale to the Company's employees,
officers and directors and other parties associated with the Company
(collectively, "PARTICIPANTS"), as set forth in the Prospectus under the heading
"Underwriting" (the "DIRECTED SHARE PROGRAM"). The Shares to be sold by such
Underwriters pursuant to the Directed Share Program (the "DIRECTED SHARES") will
be sold by such Underwriters pursuant to this Agreement at the public offering
price. Any Directed Shares not orally confirmed for purchase by any Participants
by the end of the first business day after the date on which this Agreement is
executed will be offered to the public by such Underwriters as set forth in the
Prospectus.

         1. Representations and Warranties of the Company. The Company
represents and warrants to and agrees with each of the Underwriters that:

                  (a) Subsequent to the respective dates as of which information
         is given in the Registration Statement and the Prospectus, (1) the
         Company and its subsidiaries have not incurred any material liability
         or obligation, direct or contingent, nor entered into any material
         transaction not in the ordinary course of business; (2) the Company has
         not purchased any of its outstanding capital stock in any material
         amount nor declared, paid or otherwise made any dividend or
         distribution of any kind on its capital stock other than ordinary and
         customary dividends; and (3) there has not been any material change in
         the capital stock, short-term debt or long-term debt of the Company and
         its subsidiaries, except in each case as described in the Registration
         Statement or the Prospectus.

                  (b) The Company and its subsidiaries have good and valid title
         in fee simple to all real property and good and valid title to all
         personal property owned by them which is material to the business of
         the Company and its subsidiaries, in each case free and clear of all
         liens, encumbrances and defects except such as are described in the
         Prospectus or such as do not materially affect the value of such
         property and do not interfere with the use made and proposed to be made
         of such property by the Company and its subsidiaries; and any real
         property and buildings held under lease by the Company and its
         subsidiaries are held by them under valid, subsisting and enforceable
         leases with such exceptions as are not material and do not interfere
         with the use made and proposed to be made of such property and
         buildings by the Company and its subsidiaries, in each case except as
         described in the Prospectus.

                  (c) The Company and its subsidiaries own or possess adequate
         rights in, or can acquire adequate rights in, on reasonable terms, all
         material patents, patent rights, licenses, inventions, copyrights,
         know-how (including trade secrets and other unpatented


                                       -3-

         or unpatentable proprietary or confidential information, systems or
         procedures), trademarks, service marks and trade names currently
         employed by them in connection with the business now operated by them,
         and neither the Company nor any of its subsidiaries has received any
         notice of infringement of or conflict with asserted rights of others
         with respect to any of the foregoing which, singly or in the aggregate,
         if the subject of an unfavorable decision, ruling or finding, would
         have a material adverse affect on the Company and its subsidiaries,
         taken as a whole.

                  (d) Except as described in the Prospectus, no material labor
         dispute with the employees of the Company or any of its subsidiaries
         exists, or, to the knowledge of the Company, is imminent;

                  (e) The Company and its subsidiaries are insured by the
         insurers of recognized financial responsibility against such losses and
         risks and in such amounts as are prudent and customary in the
         businesses in which they are engaged; neither the Company nor any of
         its subsidiaries (while a subsidiary of the Company) has been refused
         any insurance coverage sought or applied for; and neither the Company
         nor any of its subsidiaries has any reason to believe that it will not
         be able to renew its existing insurance coverage as and when such
         coverage expires or to obtain similar coverage from similar insurers as
         may be necessary to continue its business at a cost that would not have
         a material adverse effect on the Company and its subsidiaries, taken as
         a whole, except as described in the Prospectus.

                  (f) The Company and its subsidiaries possess all certificates,
         authorizations and permits issued by the appropriate federal, state or
         foreign regulatory authorities necessary to conduct their respective
         business except where the failure to possess such certificates,
         authorizations and permits would not have a material adverse effect on
         the Company and its subsidiaries taken as a whole, and neither the
         Company nor any of its subsidiaries has received any notice of
         proceedings relating to the revocation or modification of any such
         certificate, authorization or permit which, singly or in the aggregate,
         if the subject of an unfavorable decision, ruling or finding, would
         have a material adverse effect on the Company and its subsidiaries,
         taken as a whole, except as described the Prospectus.

                  (g) The Company and each of its subsidiaries maintain a system
         of internal accounting controls sufficient to provide reasonable
         assurance that (1) transactions are executed in accordance with
         management's general or specific authorizations; (2) transactions are
         recorded as necessary to permit preparation of financial statements in
         conformity with generally accepted accounting principles and to
         maintain asset accountability; (3) access to assets is permitted only
         in accordance with management's general or specific authorization; and
         (4) the recorded accountability for assets is compared with the
         existing assets at reasonable intervals and appropriate action is taken
         with respect to any differences.

         complied when so filed in all material respects with the Securities Act
         and the applicable rules and regulations of the Commission thereunder.

                  (t) The Company is not and, after giving effect to the
         offering and sale of the Shares and the application of the proceeds
         thereof as described in the Prospectus, will not be an "investment
         company" as such term is defined in the Investment Company Act of 1940,
         as amended.

                  (u) The Company and its subsidiaries (i) are in compliance
         with any and all applicable foreign, federal, state and local laws and

         in compliance with all terms and conditions of any such permit, license
         or approval, except as described in the Prospectus or where such
         noncompliance with Environmental Laws, failure to receive required
         permits, licenses or other approvals or failure to comply with the
         terms and conditions of such permits, licenses or approvals would not,

         Company and its subsidiaries, taken as a whole.

                  (v) There are no costs or liabilities associated with
         Environmental Laws (including, without limitation, any capital or
         operating expenditures required for clean-up, closure of properties or
         compliance with Environmental Laws or any permit, license or approval,
         any related constraints on operating activities and any potential
         liabilities to third parties) which would, singly or in the aggregate,
         have a material adverse effect on the Company and its subsidiaries,
         taken as a whole.

                  (w) There are no contracts, agreements or understandings
         between the Company and any person granting such person the right to
         require the Company to file a registration statement under the
         Securities Act with respect to any securities of the Company or to
         require the Company to include such securities with the Shares
         registered pursuant to the Registration Statement which has not been
         waived.

                  (x) The Company has reviewed its operations and that of its
         subsidiaries to evaluate the extent to which the business or operations
         of the Company or any of its subsidiaries will be affected by the Year
         2000 problem (that is, any significant risk that computer hardware or
         software applications used by the Company and its subsidiaries will
         not, in the case of dates or time periods occurring after December 31,
         1999, function at least as effectively as in the case of dates or time
         periods occurring prior to January 1, 2000) (the "YEAR 2000 PROBLEM");
         and as a result of such review, (i) the Company has no reason to
         believe, and does not believe, that (A) there are any issues related to
         the

         Company's preparedness to address the Year 2000 Problem that are of a
         character required to be described or referred to in the Registration
         Statement or Prospectus which have not been accurately described in the
         Registration Statement or Prospectus and (B) the Year 2000 Problem will
         have a material adverse effect on the condition, financial or
         otherwise, or on the earnings, business or operations of the Company
         and its subsidiaries, taken as a whole, or result in any material loss
         or interference with the business or operations of the Company and its
         subsidiaries, taken as a whole; and (ii) the Company reasonably
         believes, after due inquiry, that the suppliers, vendors, customers or
         other material third parties used or served by the Company and such
         subsidiaries are addressing or will address the Year 2000 Problem in a
         timely manner, except to the extent that a failure to address the Year
         2000 Problem by any supplier, vendor, customer or material third party
         would not have a material adverse effect on the condition, financial or
         otherwise, or on the earnings, business or operations of the Company
         and its subsidiaries, taken as a whole.

                  (y) Furthermore, the Company represents and warrants to Morgan
         Stanley and the Underwriters that are selling Shares pursuant to the
         Directed Share Program that (i) the Registration Statement, the
         Prospectus and any preliminary prospectus comply, and any further
         amendments or supplements thereto will comply, with any applicable laws
         or regulations of foreign jurisdictions in which the Prospectus or any
         preliminary prospectus, as amended or supplemented, if applicable, are
         distributed at the request of the Company in connection with the
         Directed Share Program, and (ii) no authorization, approval, consent,
         license, order, registration or qualification of or with any
         government, governmental instrumentality or court, other than such as
         have been obtained, is necessary under the securities laws and
         regulations of foreign jurisdictions in which the Directed Shares are
         offered outside the United States at the request of the Company.

                  (z) The Company has not offered, or caused the Underwriters to
         offer, Shares to any person pursuant to the Directed Share Program with
         the specific intent to unlawfully influence (i) a customer or supplier
         of the Company to alter the customer's or supplier's level or type of
         business with the Company, or (ii) a trade journalist or publication to
         write or publish favorable information about the Company or its
         products.

         2. Representations and Warranties of the Selling Stockholders. Each of

         performance of the Selling Stockholder of its obligations hereunder.

                  (c) Such Selling Stockholder has, and on the Closing Date will
         have, valid title to the Shares to be sold by such Selling Stockholder

                  "nationally recognized statistical rating organization," as
                  such term is defined for purposes of Rule 436(g)(2) under the
                  Securities Act; and

                           (ii) there shall not have occurred any change, or any
                  development involving a prospective change, in the condition,
                  financial or otherwise, or in the earnings, business or
                  operations of the Company and its subsidiaries, taken as a
                  whole, from that set forth in the Prospectus (exclusive of any
                  amendments or supplements thereto subsequent to the date of
                  this Agreement) that, in your judgment, is material and
                  adverse and that makes it, in your judgment, impracticable to

                  in the Prospectus.

                  the offering and sale of the Shares and the application of the

                  an "investment company" as such term is defined in the
                  Investment Company Act of 1940, as amended; and

                  and auditors' report thereon) and schedules and other
                  financial and statistical data included therein as to which
                  such counsel need not express any opinion) appear on their
                  face to comply as to form in all material respects with the
                  Securities Act and the applicable rules and regulations of the
                  Commission thereunder.

                  Such counsel shall also include statements to the following
         effect: Such counsel has participated in conferences with officers and
         other representatives of the Company, representatives of the
         independent public accountants and your representatives at which the
         contents of the Registration Statement and Prospectus and related
         matters were discussed. Although such counsel did not independently
         verify such information and is not passing on, and does not assume any
         responsibility for, the accuracy, completeness or fairness of the
         statements contained in the Registration Statement and the Prospectus
         (except to the extent stated in subparagraphs (iii) and (ix) of this
         paragraph (c)), such counsel advises you that, on the basis of the
         foregoing (relying as to materiality as to matters of fact in part upon
         officers and other representatives of the Company), no facts have come
         to the attention of such counsel which lead such counsel to believe
         that the Registration Statement (except for (A) the financial
         statements (including the notes thereto and the auditors' reports
         thereon) and schedules included therein, (B) the other financial and
         statistical information included therein and (C) the exhibits thereto,
         as to which such counsel has not been asked to comment), as of the time
         it became effective, contained any untrue statement of a material fact
         or omitted to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading or that the
         Prospectus (except for (x) the financial statements (including the
         notes thereto


                                      -15-

         and the auditors' reports thereon) included therein and (y) the other
         financial and statistical information included therein, as to which
         such counsel has not been asked to comment), as of the issue date
         thereof or as of the Closing Date, contained or contains any untrue
         statement of a material fact or omitted or omits to state a material
         fact necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading.

                  "Applicable Laws" means the General Corporation Law of the
         State of Delaware, the laws of the State of Texas and the laws of the
         United States of America that, in the experience of such counsel, are
         normally applicable to transactions of the type contemplated by this
         Agreement. "Applicable Governmental Authority" means any governmental
         body, agency or court of the United States of America or the State of
         Texas or (solely with respect to the General Corporation Law of the
         State of Delaware) the State of Delaware.

         an opinion of Carl E. Edwards, general counsel to the Company, dated

         7. Covenants of the Company. In further consideration of the agreements
of the Underwriters herein contained, the Company covenants with each

                  (a) To furnish to you, without charge, such number of signed
         copies of the Registration Statement (including exhibits thereto) as

         as many copies of the Prospectus and any supplements and amendments
         thereto or to the Registration Statement as you may reasonably request.

                  (b) Before amending or supplementing the Registration
         Statement or the Prospectus, to furnish to you a copy of each such
         proposed amendment or supplement and not to file any such proposed

                                      -21-

<PAGE>   23



                  (c) If, during such period after the first date of the public
         offering of the Shares as in the opinion of counsel for the
         Underwriters the Prospectus is required by law to be delivered in
         connection with sales by an Underwriter or dealer, any event shall
         occur or condition exist as a result of which it is necessary to amend
         or supplement the Prospectus in order to make the statements therein,
         in the light of the circumstances when the Prospectus

         is delivered to a purchaser, not misleading, or if, in the opinion of
         counsel for the Underwriters, it is necessary to amend or supplement
         the Prospectus to comply with applicable law, forthwith to prepare,
         file with the Commission and furnish, at its own expense, to the
         Underwriters and to the dealers (whose names and addresses you will
         furnish to the Company) to which Shares may have been sold by you on
         behalf of the Underwriters and to any other dealers upon request,
         either amendments or supplements to the Prospectus so that the
         statements in the Prospectus as so amended or supplemented will not, in
         the light of the circumstances when the Prospectus is delivered to a
         purchaser, be misleading or so that the Prospectus, as amended or
         supplemented, will comply with law.

                  (d) To endeavor to qualify the Shares for offer and sale under
         the securities or blue sky laws of such jurisdictions as you shall
         reasonably request; provided, however, that the Company shall not be
         obligated (i) to qualify as a foreign corporation in any jurisdiction
         in which it is not so qualified, (ii) to take any action that would
         subject it to taxation in any jurisdiction or (iii) to execute a
         consent to service of process under the laws of any jurisdiction
         (except service of process with respect to the offering and sale of
         Shares).

                  (e) To make generally available to the Company's security
         holders and to you as soon as practicable an earning statement covering
         the twelve-month period ending [SEPTEMBER 30,] 2000 that satisfies the
         provisions of Section 11(a) of the Securities Act and the rules and
         regulations of the Commission thereunder.

                  (f) That in connection with the Directed Share Program, the
         Company will ensure that the Directed Shares will be restricted to the
         extent required by the National Association of Securities Dealers, Inc.
         (the "NASD") or the NASD rules from sale, transfer, assignment, pledge
         or hypothecation for a period of three months following the date of the
         effectiveness of the Registration Statement. Morgan Stanley will notify
         the Company as to which Participants will need to be so restricted. The
         Company will direct the transfer agent of the Common Stock to place
         stop transfer restrictions upon such securities for such period of
         time.

                  (g) To pay all fees and disbursements of Belgian, Canadian and
         Australian counsel incurred by the Underwriters in connection with the
         Directed Share Program and stamp duties, similar taxes or duties or
         other taxes, if any, incurred by the Underwriters in connection with

                  (h) Furthermore, the Company covenants with Morgan Stanley
         that the Company will comply with all applicable securities and other
         applicable laws, rules and regulations in each foreign jurisdiction in
         which the Directed Shares are offered in connection with the Directed
         Share Program.

<PAGE>   25



provided in this Section, Section 9, and the last paragraph of Section 11 below,

         9.       Indemnity and Contribution.

                  (a) The Company agrees to indemnify and hold harmless each
         Underwriter and each person, if any, who controls any Underwriter
         within the meaning of either Section 15 of the Securities Act or
         Section 20 of the Securities Exchange Act of 1934, as amended (the
         "EXCHANGE ACT"), from and against any and all losses, claims, damages
         and liabilities (including, without limitation, any legal or other
         expenses reasonably incurred in connection with defending or
         investigating any such action or claim) caused by any untrue statement
         or alleged untrue statement of a material fact contained in the
         Registration Statement or any amendment thereof, any preliminary
         prospectus or the Prospectus (as amended or supplemented if the Company
         shall have furnished any amendments or supplements thereto), or caused
         by any omission or alleged omission to state therein a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, except insofar as such losses, claims, damages
         or liabilities are caused by any such untrue statement or omission or
         alleged untrue statement or omission based upon information relating to
         any Underwriter furnished to the Company in writing by such Underwriter
         through you expressly for use therein; provided, however, that the
         foregoing indemnity agreement with respect to any preliminary
         prospectus shall not inure to the benefit of any Underwriter from whom
         the person asserting any such losses, claims, damages or liabilities
         purchased Shares, or any person controlling such Underwriter, if a copy
         of the Prospectus (as then amended or supplemented if the Company shall
         have furnished any amendments or supplements thereto) was not sent or
         given by or on behalf of such Underwriter to such person, if required
         by law so to have been delivered, at or prior to the written
         confirmation of the sale of the Shares to such person, and if the
         Prospectus (as so amended or supplemented) would have cured the defect
         giving rise to such losses, claims, damages or liabilities, unless such
         failure is the result of noncompliance by the Company with Section 7(a)
         hereof.

                  The Company also agrees to indemnify and hold harmless Morgan
         Stanley & Co. Incorporated ("MORGAN STANLEY") and each person, if any,
         who controls Morgan Stanley within the meaning of either Section 15 of
         the Act or Section 20 of the Exchange Act from and against any and all
         losses, claims, damages, liabilities and judgments incurred as a result
         of Morgan Stanley's participation as a "qualified independent
         underwriter" within the meaning of Rule 2720 of the National
         Association of Securities Dealers'


                                      -24-

         Conduct Rules in connection with the offering of the Shares, except
         for any losses, claims, damages, liabilities and judgments resulting
         from Morgan Stanley's, or such controlling person's, willful
         misconduct.

                  (b) The Company agrees to indemnify and hold harmless Morgan
         Stanley, each other Underwriter that sells Shares pursuant to the
         Directed Share Program and each of their affiliates (including each
         person, if any, that controls Morgan Stanley or such Underwriter within
         the meaning of either Section 15 of the Securities Act or Section 20 of
         the Exchange Act) (collectively, the "DIRECTED SHARE UNDERWRITERS")
         from and against any and all losses, claims, damages and liabilities
         (including, without limitation, any legal or other expenses reasonably
         incurred in connection with defending or investigating any such action
         or claim) (i) caused by any untrue statement or alleged untrue
         statement of a material fact contained in the prospectus wrapper
         material prepared by or with the consent of the Company for
         distribution in foreign jurisdictions in connection with the Directed
         Share Program attached to the Prospectus or any preliminary prospectus,
         or caused by any omission or alleged omission to state therein a
         material fact required to be stated therein or necessary to make the
         statement therein, when considered in conjunction with the Prospectus
         or any applicable preliminary prospectus, not misleading; (ii) caused
         by the failure of any Participant to pay for and accept delivery of the
         shares which, immediately following the effectiveness of the
         Registration Statement, were subject to a properly confirmed agreement
         to purchase; or (iii) related to, arising out of, or in connection with
         the Directed Share Program, provided that the Company shall not be
         responsible under this subparagraph (iii) for any losses, claims,
         damages or liabilities (or expenses relating thereto) that are finally
         judicially determined to have resulted from the bad faith or gross
         negligence of Directed Share Underwriters; provided, however, that the
         foregoing indemnity agreement with respect to any preliminary
         prospectus shall not inure to the benefit of any Directed Share
         Underwriter from whom the person asserting any such losses, claims,
         damages or liabilities purchased Shares, or any affiliate of such
         Directed Share Underwriter, if a copy of the Prospectus (as then
         amended or supplemented if the Company shall have furnished any
         amendments or supplements thereto) was not sent or given by or on
         behalf of such Directed Share Underwriter to such person, if required
         by law so to have been delivered, at or prior to the written
         confirmation of the sale of the Shares to such person, and if the
         Prospectus (as so amended or supplemented) would have cured the defect
         giving rise to such losses, claims, damages or liabilities, unless such
         failure is the result of noncompliance by the Company with Section 7(a)
         hereof.

                  (c) Each Selling Stockholder agrees, severally and not
         jointly, to indemnify and hold harmless each Underwriter and each
         person, if any, who controls any Underwriter within the meaning of
         either Section 15 of the Securities Act or Section 20 of the Exchange
         Act, from and against any and all losses, claims, damages and
         liabilities (including, without limitation, any legal or other expenses
         reasonably incurred in connection with defending or investigating any
         such action or claim) caused by any



                                      -25-

<PAGE>   27




         untrue statement or alleged untrue statement of a material fact
         contained in the Registration Statement or any amendment thereof, any
         preliminary prospectus or the Prospectus (as amended or supplemented if
         the Company shall have furnished any amendments or supplements
         thereto), or caused by any omission or alleged omission to state
         therein a material fact required to be stated therein or necessary to
         make the statements therein not misleading, but only with reference to
         information relating to such Selling Stockholder furnished to the
         Company in writing by or on behalf of such Selling Stockholder
         expressly for use in the Registration Statement, any preliminary
         prospectus, the Prospectus or any amendments or supplements thereto;
         provided, however, that the foregoing indemnity agreement with respect
         to any preliminary prospectus shall not inure to the benefit of any
         Underwriter from whom the person asserting any such losses, claims,
         damages or liabilities purchased Shares, or any person controlling such
         Underwriter, if a copy of the Prospectus (as then amended or
         supplemented if the Company shall have furnished any amendments or
         supplements thereto) was not sent or given by or on behalf of such
         Underwriter to such person, if required by law so to have been
         delivered, at or prior to the written confirmation of the sale of the
         Shares to such person, and if the Prospectus (as so amended or
         supplemented) would have cured the defect giving rise to such losses,
         claims, damages or liabilities, unless such failure is the result of
         noncompliance by the Company with Section 7(a) hereof; provided,
         further, however, that with respect to any amount due an indemnified
         person under this paragraph (c), each Selling Stockholder shall be
         liable only to the extent of the net proceeds received by such Selling
         Stockholder from such Selling Stockholder's Shares.

                  (d) Each Underwriter agrees, severally and not jointly, to
         indemnify and hold harmless the Company, the Selling Stockholders, the
         directors of the Company, the officers of the Company who sign the
         Registration Statement and each person, if any, who controls the
         Company or any Selling Stockholder within the meaning of either Section
         15 of the Securities Act or Section 20 of the Exchange Act from and
         against any and all losses, claims, damages and liabilities (including,
         without limitation, any legal or other expenses reasonably incurred in
         connection with defending or investigating any such action or claim)
         caused by any untrue statement or alleged untrue statement of a
         material fact contained in the Registration Statement or any amendment
         thereof, any preliminary prospectus or the Prospectus (as amended or
         supplemented if the Company shall have furnished any amendments or
         supplements thereto), or caused by any omission or alleged omission to
         state therein a material fact required to be stated therein or
         necessary to make the statements therein not misleading, but only with
         reference to information relating to such Underwriter furnished to the
         Company in writing by or on behalf of such Underwriter through you
         expressly for use in the Registration Statement, any preliminary
         prospectus, the Prospectus or any amendments or supplements thereto.

                  (e) In case any proceeding (including any governmental
         investigation) shall be instituted involving any person in respect of
         which indemnity may be sought pursuant to Section 9(a), 9(b), 9(c) or
         9(d), such person (the "INDEMNIFIED PARTY") shall promptly


                                      -26-

<PAGE>   28




         notify the person against whom such indemnity may be sought (the
         "INDEMNIFYING PARTY") in writing and the indemnifying party, upon
         request of the indemnified party, shall retain counsel reasonably
         satisfactory to the indemnified party to represent the indemnified
         party and any others the indemnifying party may designate in such
         proceeding and shall pay the fees and disbursements of such counsel
         related to such proceeding. In any such proceeding, any indemnified
         party shall have the right to retain its own counsel, but the fees and
         expenses of such counsel shall be at the expense of such indemnified
         party unless (i) the indemnifying party and the indemnified party shall
         have mutually agreed to the retention of such counsel or (ii) the named
         parties to any such proceeding (including any impleaded parties)
         include both the indemnifying party and the indemnified party and
         representation of both parties by the same counsel would be
         inappropriate due to actual or potential differing interests between
         them. It is understood that the indemnifying party shall not, in
         respect of the legal expenses of any indemnified party in connection
         with any proceeding or related proceedings in the same jurisdiction, be
         liable for (x) the fees and expenses of more than one separate firm (in
         addition to any local counsel) for all Underwriters and all persons, if
         any, who control any Underwriter within the meaning of either Section
         15 of the Securities Act or Section 20 of the Exchange Act, (y) the
         fees and expenses of more than one separate firm (in addition to any
         local counsel) for the Company, its directors, its officers who sign
         the Registration Statement and each person, if any, who controls the
         Company within the meaning of either such Section and (z) the fees and
         expenses of more than one separate firm (in addition to any local
         counsel) for all Selling Stockholders and all persons, if any, who
         control any Selling Stockholder within the meaning of either such
         Section, and that all such fees and expenses shall be reimbursed as
         they are incurred. Notwithstanding anything contained herein to the
         contrary, if indemnity may be sought pursuant to the second paragraph
         of Section 9(a) hereof in respect of such action or proceeding, then in
         addition to such separate firm for the indemnified parties, the
         indemnifying party shall be liable for the reasonable fees and expenses
         of not more than one separate firm (in addition to any local counsel)
         for Morgan Stanley in its capacity as a "qualified independent
         underwriter" and all persons, if any, who control Morgan Stanley within
         the meaning of either Section 15 of the Act or Section 20 of the
         Exchange Act. In the case of any such separate firm for the
         Underwriters and such control persons of any Underwriters, such firm
         shall be designated in writing by Morgan Stanley. In the case of any
         such separate firm for the Company, and such directors, officers and
         control persons of the Company, such firm shall be designated in
         writing by the Company. In the case of any such separate firm for the
         Selling Stockholders and such control persons of any Selling
         Stockholders, such firm shall be designated in writing by the persons
         named as attorneys-in-fact for the Selling Stockholders under the
         Powers of Attorney. The indemnifying party shall not be liable for any
         settlement of any proceeding effected without its written consent, but
         if settled with such consent or if there be a final judgment for the
         plaintiff, the indemnifying party agrees to indemnify the indemnified
         party from and against any loss or liability by reason of such
         settlement or judgment. No indemnifying party shall, without the prior
         written consent of the indemnified party, effect any settlement of any
         pending or


                                      -27-

<PAGE>   29




         threatened proceeding in respect of which any indemnified party is or
         could have been a party and indemnity could have been sought hereunder
         by such indemnified party, unless such settlement includes an
         unconditional release of such indemnified party from all liability on
         claims that are the subject matter of such proceeding.

                  (f) To the extent the indemnification provided for in Section
         9(a), 9(b), 9(c) or 9(d) is unavailable to an indemnified party or
         insufficient in respect of any losses, claims, damages or liabilities
         referred to therein, then each indemnifying party under such paragraph,
         in lieu of indemnifying such indemnified party thereunder, shall
         contribute to the amount paid or payable by such indemnified party as a
         result of such losses, claims, damages or liabilities (i) in such
         proportion as is appropriate to reflect the relative benefits received
         by the indemnifying party or parties on the one hand and the
         indemnified party or parties on the other hand from the offering of the
         Shares or (ii) if the allocation provided by clause 9(f)(i) above is
         not permitted by applicable law, in such proportion as is appropriate
         to reflect not only the relative benefits referred to in clause 9(f)(i)
         above but also the relative fault of the indemnifying party or parties
         on the one hand and of the indemnified party or parties on the other
         hand in connection with the statements or omissions that resulted in
         such losses, claims, damages or liabilities, as well as any other
         relevant equitable considerations. The relative benefits received by
         the Sellers on the one hand and the Underwriters on the other hand in
         connection with the offering of the Shares shall be deemed to be in the
         same respective proportions as the net proceeds from the offering of
         the Shares (before deducting expenses) received by each Seller and the
         total underwriting discounts and commissions received by the
         Underwriters, in each case as set forth in the table on the cover of
         the Prospectus, bear to the aggregate Public Offering Price of the
         Shares. The relative fault of the Sellers on the one hand and the
         Underwriters on the other hand shall be determined by reference to,
         among other things, whether the untrue or alleged untrue statement of a
         material fact or the omission or alleged omission to state a material
         fact relates to information supplied by the Sellers or by the
         Underwriters and the parties' relative intent, knowledge, access to
         information and opportunity to correct or prevent such statement or
         omission. The Underwriters' respective obligations to contribute
         pursuant to this Section 9 are several in proportion to the respective
         number of Shares they have purchased hereunder, and not joint.

                  (g) The Sellers and the Underwriters agree that it would not
         be just or equitable if contribution pursuant to this Section 9 were
         determined by pro rata allocation (even if the Underwriters were
         treated as one entity for such purpose) or by any other method of
         allocation that does not take account of the equitable considerations
         referred to in Section 9(f). The amount paid or payable by an
         indemnified party as a result of the losses, claims, damages and
         liabilities referred to in the immediately preceding paragraph shall be
         deemed to include, subject to the limitations set forth above, any
         legal or other expenses reasonably incurred by such indemnified party
         in connection with investigating or defending any such action or claim.
         Notwithstanding the provisions of this Section 9,


                                      -28-

<PAGE>   30




         (i) no Underwriter shall be required to contribute any amount in excess
         of the amount by which the total price at which the Shares underwritten
         by it and distributed to the public were offered to the public exceeds
         the amount of any damages that such Underwriter has otherwise been
         required to pay by reason of such untrue or alleged untrue statement or
         omission or alleged omission and (ii) no Selling Stockholder shall be
         required to contribute any amount in excess of the amount by which the
         proceeds received by such Selling Stockholder in connection herewith
         exceed the aggregate amount such Selling Stockholder has otherwise been
         requested to pay pursuant hereto. No person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the
         Securities Act) shall be entitled to contribution from any person who
         was not guilty of such fraudulent misrepresentation. The remedies
         provided for in this Section 9 are not exclusive and shall not limit
         any rights or remedies which may otherwise be available to any
         indemnified party at law or in equity.

                  (h) The indemnity and contribution provisions contained in
         this Section 9 and the representations, warranties and other statements
         of the Company and the Selling Stockholders contained in this Agreement
         shall remain operative and in full force and effect regardless of (i)
         any termination of this Agreement, (ii) any investigation made by or on
         behalf of any Underwriter, any person controlling any Underwriter, any
         affiliate of any Underwriter that is selling Shares pursuant to the
         Directed Share Program, any Selling Stockholder or any person
         controlling any Selling Stockholder, or the Company, its officers or
         directors or any person controlling the Company and (iii) acceptance of
         and payment for any of the Shares.

         10. Termination. This Agreement shall be subject to termination by
notice given by you to the Company, if (a) after the execution and delivery of
this Agreement and prior to the Closing Date (i) trading generally shall have
been suspended or materially limited on or by, as the case may be, any of the
New York Stock Exchange, the American Stock Exchange, the National Association
of Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago
Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any
securities of the Company shall have been suspended on any exchange or in any
over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York shall have been declared by either Federal or New York
State authorities or (iv) there shall have occurred any outbreak or escalation
of hostilities or any change in financial markets or any calamity or crisis
that, in your judgment, is material and adverse and (b) in the case of any of
the events specified in clauses 10(a)(i) through 10(a)(iv), such event, singly
or together with any other such event, makes it, in your judgment, impracticable
to market the Shares on the terms and in the manner contemplated in the
Prospectus.

         11. Effectiveness; Defaulting Underwriters. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.

         If, on the Closing Date or the Option Closing Date, as the case may be,
any one or more


                                      -29-

<PAGE>   31



of the Underwriters shall fail or refuse to purchase Shares that it has or they
have agreed to purchase hereunder on such date, and the aggregate number of
Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase is not more than one-tenth of the aggregate number of the
Shares to be purchased on such date, the other Underwriters shall be obligated
severally in the proportions that the number of Firm Shares set forth opposite
their respective names in Schedule II and Schedule III bears to the aggregate
number of Firm Shares set forth opposite the names of all such non-defaulting
Underwriters, or in such other proportions as you may specify, to purchase the
Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase on such date; provided that in no event shall the number of
Shares that any Underwriter has agreed to purchase pursuant to this Agreement be
increased pursuant to this Section 11 by an amount in excess of one-ninth of
such number of Shares without the written consent of such Underwriter. If, on
the Closing Date, any Underwriter or Underwriters shall fail or refuse to
purchase Firm Shares and the aggregate number of Firm Shares with respect to
which such default occurs is more than one-tenth of the aggregate number of Firm
Shares to be purchased, and arrangements satisfactory to you, the Company and
the Selling Stockholders for the purchase of such Firm Shares are not made
within 36 hours after such default, this Agreement shall terminate without
liability on the part of any non-defaulting Underwriter, the Company or the
Selling Stockholders. In any such case either you or the relevant Sellers shall
have the right to postpone the Closing Date, but in no event for longer than
seven days, in order that the required changes, if any, in the Registration
Statement and in the Prospectus or in any other documents or arrangements may be
effected. If, on the Option Closing Date, any Underwriter or Underwriters shall
fail or refuse to purchase Additional Shares and the aggregate number of
Additional Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Additional Shares to be purchased, the
non-defaulting Underwriters shall have the option to (i) terminate their
obligation hereunder to purchase Additional Shares or (ii) purchase not less
than the number of Additional Shares that such non-defaulting Underwriters would
have been obligated to purchase in the absence of such default. Any action taken
under this paragraph shall not relieve any defaulting Underwriter from liability
in respect of any default of such Underwriter under this Agreement.

         If this Agreement shall be terminated by the Underwriters, or any of
them, because of any failure or refusal on the part of any Seller to comply with
the terms or to fulfill any of the conditions of this Agreement, or if for any
reason any Seller shall be unable to perform its obligations under this
Agreement, the Sellers will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

         12. Counterparts. This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         13. Applicable Law. This Agreement shall be governed by and construed
in accordance with the internal laws of the State of New York.

Ladies and Gentlemen:

         The undersigned understands that Morgan Stanley & Co. Incorporated and
Morgan Stanley & Co. International Limited (collectively "MORGAN STANLEY")
propose to enter into an Underwriting Agreement (the "UNDERWRITING AGREEMENT")
with Lennox International Inc., a Delaware corporation (the "COMPANY"),
providing for the public offering (the "PUBLIC OFFERING") by the several
Underwriters, including Morgan Stanley (the "UNDERWRITERS"), of ______________
shares (the "SHARES") of the common stock, par value $.01 per share, of the
Company (the "COMMON STOCK").

         To induce the Underwriters that may participate in the Public Offering
to continue their efforts in connection with the Public Offering, the
undersigned hereby agrees that, without the prior written consent of Morgan
Stanley on behalf of the Underwriters, it will not, during the period commencing
on the date hereof and ending 180 days after the date of the final prospectus
relating to the Public Offering (the "PROSPECTUS"), (1) 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, lend 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 (2) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of
Common Stock, whether any such transaction described in clause (1) or (2) above
is to be settled by delivery of Common Stock or such other securities, in cash
or otherwise; PROVIDED, HOWEVER, that the undersigned shall be permitted to make
a bona fide gift of shares of Common Stock during such period if the undersigned
delivers to Morgan Stanley a letter substantially similar to this letter
executed by the donee. The foregoing sentence shall not apply to (a) the sale of
any Shares to the Underwriters pursuant to the Underwriting Agreement or (b)
transactions relating to shares of Common Stock or other securities acquired in
open market transactions after the completion of the Public Offering. In
addition, the undersigned agrees that, without the prior written consent of
Morgan Stanley on behalf of the Underwriters, it will not, during the period
commencing on the date

hereof and ending 180 days after the date of the Prospectus, make any demand for
or exercise any right with respect to, the registration of any shares of Common
Stock or any security convertible into or exercisable or exchangeable for Common
Stock.

         Whether or not the Public Offering actually occurs depends on a number
of factors, including market conditions. Any Public Offering will only be made
pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the Underwriters.

                                            Very truly yours,

Ladies and Gentlemen:

                  As set forth in the Registration Statement on Form S-1
(Registration No. 333-75725), as amended (the "Registration Statement"), filed
by Lennox International Inc., a Delaware corporation (the "Company"), with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended (the "Act"), relating to the issuance and sale of up to an
aggregate of 9,775,000 shares (the "Shares") of its Common Stock, par value
$0.01 per share, the validity of the Shares is being passed upon for you by us.
The Shares include (i) 8,088,490 Shares being issued and sold by the Company,
(ii) 411,510 Shares being sold by the selling stockholders identified in the
Registration Statement (the "Selling Stockholders") and (iii) 1,275,000 Shares
that may be issued and sold by the Company pursuant to an over-allotment option
(the "Over-Allotment Option") granted to the Underwriters named in the

hereinafter referred to as the "Company Shares" and the Shares identified in
clause (ii) above are hereinafter referred to as the "Selling Stockholder
Shares." At your request, this opinion is being furnished to you for filing as
Exhibit 5.1 to the Registration Statement.

                  In our capacity as counsel to the Company in connection with
the registration and proposed issuance and sale of the Shares, we have
familiarized ourselves with (i) the Company's Restated Certificate of
Incorporation (the "Restated Certificate of Incorporation"), as filed as an
exhibit to the Registration Statement and (ii) the Company's Amended and
Restated Bylaws, as filed as an exhibit to the Registration Statement, and have
examined the originals, or copies certified or otherwise identified, of
corporate records of the Company, including minutes of the Company, certificates
of public officials and of representatives of the Company, statutes and other
instruments and documents as a basis for the opinions hereinafter expressed. In
giving such opinions, we have relied upon certificates of public officials and
representatives of the Company with respect to the accuracy of the material
factual matters contained in such certificates.

                  Based on our examination as aforesaid, and subject to the
assumptions, limitations and qualifications hereinafter set forth, we are of the
opinion that:

         existing in good standing under the laws of the State of Delaware.

                  2. When the Board of Directors of the Company or the duly
         authorized Pricing Committee of the Board of Directors of the Company
         shall have fixed the price at which the Shares are to be sold all
         requisite corporate action on the part of the Company with respect to
         the authorization of the Company Shares will have been taken. Upon the
         occurrence of the event specified in the immediately preceding sentence
         and upon the sale of the Company Shares for the price approved by the
         Board of Directors of the Company or the duly authorized Pricing
         Committee of the Board of Directors of the Company, the Company Shares
         will be validly issued, fully paid and nonassessable.

                  3. The Selling Stockholder Shares have been duly authorized
         and validly issued and are fully paid and nonassessable.

                  The opinions set forth above are limited to matters governed
by the General Corporation Law of the State of Delaware as in effect on the date
hereof.

                  We hereby consent to the filing of this opinion with the
Securities and Exchange Commission as an exhibit to the Registration Statement
and to the reference to us under the caption "Legal Matters" in the Prospectus
forming a part of the Registration Statement. In giving such consent, we do not
thereby admit that we are within the category of persons whose consent is
required under Section 7 of the Act or the Rules and Regulations of the
Commission thereunder.

syndication agent (in such capacity, the "Syndication Agent") and THE BANK OF

credit on the terms and subject to the conditions herein set forth.

shall, upon request, provide to the Borrower a certificate setting forth in
reasonable detail the basis for such determination) that it is unable to

of the first sentence of this definition until the circumstances giving rise to
such inability no longer exist. Any change in the Alternate Base Rate due to a
change in the Prime Rate or the Federal Funds Effective Rate shall be effective
on the effective date of such change in the Prime Rate or the Federal Funds
Effective Rate, respectively.

         "Applicable Governmental Authority" means, a United States Governmental
Authority or the government of any jurisdiction in which the Borrower or any
Subsidiary conducts all or any part of its business, or which asserts

All references herein to Articles, Sections, Exhibits and Schedules shall be

expressly provided herein, all terms of an accounting or financial nature shall
be construed in accordance with GAAP, as in effect from time to time.

ARTICLE 2.        THE CREDITS

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

SECTION 2.02.     Loans.

         (a) Each Loan shall be made as part of a Borrowing consisting of Loans
made by the Lenders ratably in accordance with the percentage of their
respective Commitments to the Total


REVOLVING CREDIT FACILITY AGREEMENT -- Page 14
<PAGE>   19

Commitment; provided, however, that the failure of any Lender to make any Loan
shall not in itself relieve any other Lender of its obligation to lend hereunder
(it being understood, however, that no Lender shall be responsible for the
failure of any other Lender to make any Loan required to be made by such other
Lender). The Loans comprising any Borrowing shall be in an aggregate principal
amount which is an integral multiple of $1,000,000 and not less than $5,000,000
(or an aggregate principal amount equal to the remaining balance of the
Commitments).


         (b) Each Borrowing shall be comprised entirely of Eurodollar Loans or
ABR Loans, as the Borrower may request pursuant to Section 2.03. Each Lender may
at its option make any Eurodollar Loan by causing any domestic or foreign branch
or Affiliate of such Lender to make such Loan; provided that any exercise of
such option shall not affect the obligation of the Borrower to repay such Loan
in accordance with the terms of this Agreement. Borrowings of more than one Type
may be outstanding at the same time.


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

         (d) Borrower may Convert all or any part of any Borrowing to a
Borrowing of a different Type and Borrower may Continue all or any part of any
Eurodollar Borrowing as a Borrowing of the same Type, by giving the
Administrative Agent written notice on the Business Day of the Conversion into
an ABR Borrowing and on the Business Day at least three Business Days before


REVOLVING CREDIT FACILITY AGREEMENT -- Page 15
<PAGE>   20

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


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


         SECTION 2.04. Fees.

         (a) The Borrower agrees to pay to each Lender, through the
Administrative Agent, on each March 31, June 30, September 30 and December 31
(with the first payment being due on September 30, 1999) and on each date on
which the Commitment of such Lender shall be terminated as provided herein, a
commitment fee (a "Commitment Fee"), at a rate per annum equal to the Commitment
Fee Percentage from time to time in effect on the amount of the daily


REVOLVING CREDIT FACILITY AGREEMENT -- Page 16
<PAGE>   21

average of the unused Commitment of such Lender, during the preceding quarter
(or other period commencing on the Effective Date or ending with the Maturity
Date or any date on which the Commitment of such Lender shall be terminated).
All Commitment Fees shall be computed on the basis of the actual number of days
elapsed in a year of 365 or 366 days, as the case may be. The Commitment Fee due
to each Lender shall commence to accrue on the Effective Date, and shall cease
to accrue on the earlier of the Maturity Date or the termination of the
Commitment of such Lender as provided herein.

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

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


SECTION 2.05. Repayment of
Loans; Evidence of Indebtedness.

         (a) The outstanding principal balance of each Loan shall be due and
payable on the Maturity Date.

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

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

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


REVOLVING CREDIT FACILITY AGREEMENT -- Page 17
<PAGE>   22

         SECTION 2.06. Interest on Loans; Margin and Fees.

         (a) Subject to the provisions of Section 2.07, the Loans comprising
each Eurodollar Borrowing shall bear interest (computed on the basis of the
actual number of days elapsed over a year of 360 days) at a rate per annum equal
to the LIBO Rate for the Interest Period in effect for such Borrowing plus the
Applicable Margin from time to time in effect.

         (b) Subject to the provisions of Section 2.07, the Loans comprising
each ABR Borrowing shall bear interest (computed on the basis of the actual
number of days elapsed over a year of 365 or 366 days, as the case may be, for
periods during which the Alternate Base Rate is determined by reference to the
Prime Rate and 360 days for other periods and including for all calculations the
first day of any period but excluding the last) at a rate per annum equal to the
Alternate Base Rate.

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

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

                  "Applicable Margin" shall mean (i) during the period
         commencing on the Effective Date and ending on but not including the
         first Adjustment Date (as defined below), 0.75% per annum and (ii)
         during each period from and including one Adjustment Date to but
         excluding the next Adjustment Date (herein a "Calculation Period"), the
         percent per annum set forth in the table below under the heading
         "Margin" opposite the Debt to Adjusted EBITDA Ratio which corresponds

                  "Commitment Fee Percentage" shall mean (1) during the period
         commencing on the Effective Date and ending on but not including the

         Upon delivery of the Compliance Certificate pursuant to Section 5.20(g)
in connection with the financial statements of the Borrower and its Subsidiaries
required to be delivered pursuant to Sections 5.20(a) and (b), commencing with
such Compliance Certificate delivered with respect to the fiscal quarter ending
on June 30, 1999, the Applicable Margin (for Interest Periods commencing after
the applicable Adjustment Date) and the Commitment Fee Percentage shall
automatically be adjusted in accordance with the Debt to Adjusted EBITDA Ratio
set forth therein and the table set forth above, such automatic adjustment to
take effect as of the first Business Day after the receipt by the Agent of the
related Compliance Certificate pursuant to Section 5.20(g) (each such Business
Day when such margin or fees change pursuant to this sentence or the next
following sentence, herein an "Adjustment Date"). If the Borrower fails to
deliver such Compliance Certificate which so sets forth the Debt to Adjusted
EBITDA Ratio within the period of time required by Section 5.20(g): (i) the
Applicable Margin (for Interest Periods commencing after the applicable
Adjustment Date) shall automatically be adjusted to 1.125.% per annum; and (ii)
the Commitment Fee Percentage shall automatically be adjusted to 0.300% per
annum, such automatic adjustments to take effect as of the first Business Day
after the last day on which the Borrower was required to deliver the applicable
Compliance Certificate in accordance with Section 5.20(g) and to remain in
effect until subsequently adjusted in accordance herewith upon the delivery of a
Compliance Certificate.

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

         SECTION 2.08. Alternate Rate of Interest. In the event, and on each
occasion, that prior to the commencement of any Interest Period for a Eurodollar
Borrowing the Administrative Agent shall have determined (i) that dollar
deposits in the principal amounts of the Eurodollar Loans comprising such
Borrowing are not generally available in the London interbank market or (ii)
that reasonable means do not exist for ascertaining the LIBO Rate, the
Administrative Agent shall, as soon as practicable thereafter, give telecopy
notice of such determination to the Borrower and the Lenders. In the event of
any such determination under clauses (i) or (ii) above, until the Administrative
Agent shall have advised the Borrower and the Lenders that the circumstances
giving rise to such notice no longer exist, any request by the Borrower for a
Eurodollar Borrowing pursuant to Section 2.03 shall be deemed to be a request
for an ABR Borrowing. In the event the


REVOLVING CREDIT FACILITY AGREEMENT -- Page 19
<PAGE>   24

Required Lenders notify the Administrative Agent that the rates at which dollar
deposits are being offered will not adequately and fairly reflect the cost to
such Lenders of making or maintaining Eurodollar Loans during such Interest
Period, the Administrative Agent shall notify the Borrower of such notice and
until the Required Lenders shall have advised the Administrative Agent that the
circumstances giving rise to such notice no longer exist, any request by the
Borrower for a Eurodollar Borrowing shall be deemed a request for an ABR
Borrowing. Each determination by the Administrative Agent hereunder shall be
made in good faith and shall be conclusive absent manifest error; provided that
the Administrative Agent, shall, upon request, provide to the Borrower a
certificate setting forth in reasonable detail the basis for such determination.

         SECTION 2.09. Termination and Reduction of Commitments.

         (a) The Commitments shall be automatically terminated on the Maturity
Date. A Commitment of a Lender may also terminate as provided in Section
2.10(c).

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

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

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

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


REVOLVING CREDIT FACILITY AGREEMENT -- Page 20
<PAGE>   25
         (b) On the date of any termination or reduction of the Total Commitment
pursuant to Section 2.09, the Borrower shall pay or prepay so much of the
Borrowings as shall be necessary in order that the aggregate principal amount of
the Loans outstanding will not exceed the Total Commitment, after giving effect
to such termination or reduction.

         (c) At least 15 Business Days (or, in the case of any transaction
permitted by Section 5.10 resulting in a Change of Control, at least 45 days)
and not more than 90 days prior to the occurrence of any Change of Control, the
Borrower will give written notice thereof to each Lender. Such notice shall
contain (i) an offer by the Borrower to prepay, on the date of such Change of
Control or, if such notice shall be delivered less than 35 days prior to the
date of such Change of Control, on the date 35 days after the date of such
notice (the "Prepayment Date"), all Loans made by each Lender, together with
interest accrued thereon to the Prepayment Date and all other obligations owed
to such Lender under the terms hereof, (ii) the estimated amount of accrued
interest, showing in reasonable detail the calculation thereof and (iii) the
Borrower's estimate of the date on which such Change of Control shall occur.
Said offer shall be deemed to lapse as to any such Lender which has not replied
affirmatively thereto in writing within 35 days of the giving of such notice. As
soon as practicable (and in any event at least 24 hours) prior to such Change of
Control, the Borrower shall give written confirmation of the date thereof to
each such Lender that has affirmatively replied to the notice given pursuant to
the first sentence of this Section 2.10(c). Borrower shall, on the Prepayment
Date, prepay to each Lender that has affirmatively replied to the notice given
pursuant to the first sentence of this Section 2.10(c) all Loans then held by
such Lender together with accrued interest thereon and all other obligations
owed to such Lender under the terms hereof. Upon such payment, the Commitment of
each Lender that shall have received such prepayment shall terminate and the
Total Commitment shall be reduced accordingly.

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

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

                  (ii) "Norris Family" means all persons who are lineal
         descendants of D.W. Norris (by birth or adoption), all spouses of such
         descendants, all estates of such descendants or spouses which are in
         the course of administration, all trusts for the benefit of such
         descendants or spouses, and all corporations or other entities in
         which, directly or indirectly, such descendants or spouses (either
         alone or in conjunction with other such descendants or spouses) have
         the right, whether by ownership of stock or other equity interests or
         otherwise, to direct the management and policies of such corporations
         or other


REVOLVING CREDIT FACILITY AGREEMENT -- Page 21
<PAGE>   26

         entities (each such person, spouse, estate, trust, corporation or
         entity being referred to herein as a "member" of the Norris Family). In
         addition, so long as any employee stock ownership plan exercises its
         Voting Rights in the same manner as members of the Norris Family
         (exclusive of employee stock ownership plans) who have a majority of
         the Voting Rights exercised by all such members of the Norris Family,
         such employee stock ownership plan shall be deemed a member of the
         Norris Family.

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

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

         SECTION 2.11. Reserve Requirements; Change in Circumstances.

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

         (b) If any Lender shall have determined that the adoption of any law,
rule, regulation or guideline arising out of the July 1988 report of the Basle
Committee on Banking Regulations and Supervisory Practices entitled
"International Convergence of Capital Measurement and Capital Standards," or the
adoption after the date hereof of any other law, rule, regulation or guideline


REVOLVING CREDIT FACILITY AGREEMENT -- Page 22
<PAGE>   27

regarding capital adequacy, or any change in any of the foregoing or in the
interpretation or administration of any of the foregoing by any Governmental
Authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or any lending office of
such Lender) or any Lender's holding company with any request or directive
regarding capital adequacy (whether or not having the force of law) of any such
authority, central bank or comparable agency, has or would have the effect of
reducing the rate of return on such Lender's capital or on the capital of such
Lender's holding company, if any, as a consequence of this Agreement, such
Lender's Commitment or the Loans made by such Lender pursuant hereto to a level
below that which such Lender or such Lender's holding company could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's policies and the policies of such Lender's holding company with
respect to capital adequacy) by an amount deemed by such Lender to be material,
then from time to time such additional amount or amounts as will compensate such
Lender for any such reduction suffered will be paid by the Borrower to such
Lender.

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

         (d) Failure on the part of any Lender to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
return on capital of the type described in paragraph (a) or (b) of this Section
2.11 with respect to any period shall not constitute a waiver of such Lender's
right to demand compensation with respect to such period or any other period;
provided, however, that no Lender shall be entitled to compensation under this
Section 2.11 for any costs incurred or reductions suffered with respect to any
date unless it shall have notified the Borrower that it will demand compensation
for such costs or reductions under paragraph (c) above not more than 90 days
after the later of (i) such date and (ii) the date on which it shall have become
aware of such costs or reductions. The protection of this Section shall be
available to each Lender regardless of any possible contention of the invalidity
or inapplicability of the law, rule, regulation, guideline or other change or
condition which shall have occurred or been imposed.

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



REVOLVING CREDIT FACILITY AGREEMENT -- Page 23
<PAGE>   28

         SECTION 2.12. Change in Legality.

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

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

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

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

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

         SECTION 2.13. Pro Rata Treatment. Except as required under Sections
2.12 and 2.17, each Borrowing, each payment or prepayment of principal of any
Borrowing, each payment of interest on the Loans, each payment of the Commitment
Fees, each Conversion or Continuation of any Loans, and each reduction of the
Total Commitment, shall be allocated pro rata among the Lenders in accordance
with their respective Commitments (or, if such Commitments shall have expired or
been terminated, in accordance with the respective principal amounts of their
outstanding Loans).

         SECTION 2.14. Sharing of Setoffs. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim, or
pursuant to a secured claim under Section 506 of Title 11 of the United States
Code or other security or interest arising from, or in lieu of, such secured
claim, received by such Lender under any applicable bankruptcy, insolvency or
other similar law or otherwise, or by any other means, obtain payment (voluntary
or involuntary) in respect of any Loan or Loans as a result of which the unpaid
principal portion of its Loans shall be proportionately less than the unpaid
principal portion of the Loans of any other



REVOLVING CREDIT FACILITY AGREEMENT -- Page 24
<PAGE>   29

Lender, it shall be deemed simultaneously to have purchased from such other
Lender at face value, and shall promptly pay to such other Lender the purchase
price for, a participation in the Loans of such other Lender, so that the
aggregate unpaid principal amount of the Loans and participations in the Loans
held by each Lender shall be in the same proportion to the aggregate unpaid
principal amount of all Loans then outstanding as the principal amount of its
Loans prior to such exercise of banker's lien, setoff or counterclaim or other
event was to the principal amount of all Loans outstanding prior to such
exercise of banker's lien, setoff or counterclaim or other event; provided,
however, that, if any such purchase or purchases or adjustments shall be made
pursuant to this Section 2.14 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustment restored without interest. The Borrower expressly consents to the
foregoing arrangements and agrees that any Lender holding a participation in a
Loan deemed to have been so purchased may exercise any and all rights of
banker's lien, setoff or counterclaim with respect to any and all moneys owing
by the Borrower to such Lender by reason thereof as fully as if such Lender had
made a Loan in the amount of such participation.

         SECTION 2.15. Payments.

         (a) The Borrower shall make each payment (including principal of or
interest on any Borrowing or any Fees or other amounts, hereunder from an
account in the United States not later than 12:00 noon, New York, New York time,
on the date when due in dollars to the Administrative Agent at its offices at 1
Chase Manhattan Plaza, 8th Floor, New York, New York 10081, in immediately
available funds.

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

         SECTION 2.16. Taxes.

         (a) Any and all payments of principal and interest on any Borrowings,
or of any Fees or indemnity or expense reimbursements by the Borrower hereunder
("Borrower Payments") shall be made, in accordance with Section 2.15, free and
clear of and without deduction for any and all current or future federal, state,
local and other governmental taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect to the Borrower Payments, but
only to the extent reasonably attributable to the Borrower Payments, excluding
(i) income taxes imposed on the net income of either Agent or any Lender (or any
transferee or assignee thereof, including a participation holder (any such
entity a "Transferee")) and (ii) franchise taxes imposed on the net income of
either Agent or any Lender (or Transferee), in each case by the jurisdiction
under the laws of which such Agent or such Lender (or Transferee) is organized
or doing business through offices or branches located therein, or any political
subdivision thereof (all such nonexcluded


REVOLVING CREDIT FACILITY AGREEMENT -- Page 25
<PAGE>   30

taxes, levies, imposts, deductions, charges, withholdings and liabilities,
collectively or individually, "Taxes"). If the Borrower shall be required to
deduct any Taxes from or in respect of any sum payable hereunder to any Lender
(or any Transferee) or the respective Agent, (i) the sum payable shall be
increased by the amount (an "additional amount") necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 2.16) such Lender (or Transferee) or Agent (as the
case may be) shall receive an amount equal to the sum it would have received had
no such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

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

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

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


REVOLVING CREDIT FACILITY AGREEMENT -- Page 26
<PAGE>   31

Transferee) or such Agent, agrees to repay the amount paid over to the Borrower
(plus penalties, interest or other charges) to such Lender (or Transferee) or
such Agent in the event such Lender (or Transferee) or such Agent is required to
repay such refund to such Governmental Authority.

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

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

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

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


REVOLVING CREDIT FACILITY AGREEMENT -- Page 27
<PAGE>   32

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

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

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

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

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

ARTICLE 3. REPRESENTATIONS AND WARRANTIES

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

         SECTION 3.01. Organization; Powers. Borrower (a) is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization, (b) has all requisite power and authority to
own its property and assets and to carry on its business as now conducted and as
proposed to be conducted, (c) is qualified to do business in every jurisdiction
where such qualification is required, except where the failure so to qualify
would not result in a Material Adverse Effect, and (d) has the corporate power
and authority to execute, deliver and perform its obligations under this
Agreement and to borrow hereunder.

         SECTION 3.02. Authorization. The execution, delivery and performance by
the Borrower of this Agreement and the Borrowings hereunder (collectively, the
"Transactions") (a) have been duly authorized by all requisite corporate action
and (b) will not (i) violate (A) any provision of any law, statute, rule or
regulation to which the Borrower is subject or of the certificate of
incorporation or other constituent documents or by-laws of the Borrower or any
of its Subsidiaries, (B) any order of any Applicable Governmental Authority or
(C), after giving effect to the consents required by Section 4.02 (g), any
provision of any Material indenture, agreement or other instrument to which the
Borrower or any of its Subsidiaries is a party or by which it or any of its
property is or may be bound (including the Senior Note Purchase Agreements and
the Indebtedness limitations set forth in Sections 10.4 and 10.9 thereof), (ii)
be in conflict with, result in a breach of or constitute (alone or with notice
or lapse of time or both) a default under any such indenture, agreement or other
instrument or (iii) result in the creation or imposition of any Lien upon any
property or assets of the Borrower.

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

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

         SECTION 3.05. Organization and Ownership of Shares of Subsidiaries.

         (a) Schedule 3.05 is (except as noted therein) a complete and correct
list of the Borrower's Subsidiaries as of June 30, 1999, showing, as to each
Subsidiary, the correct name thereof, the jurisdiction of its organization, the
percentage of shares of each class of its capital stock or similar equity
interests outstanding owned by the Borrower and each other Subsidiary, and
specifying whether such Subsidiary is designated a Restricted Subsidiary.


REVOLVING CREDIT FACILITY AGREEMENT -- Page 29
<PAGE>   34

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

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

         SECTION 3.06. Financial Statements. The Borrower has delivered to some
or all of the Lenders copies of the financial statements of the Borrower and its
Subsidiaries listed on Schedule 3.06. All of the financial statements listed on
Schedule 3.06 (including in each case the related schedules and notes) fairly
present in all material respects the consolidated financial position of the
Borrower and its Subsidiaries, and of the Borrower and its Restricted
Subsidiaries, as of the respective dates specified in such Schedule and the
consolidated results of their operations and cash flows for the respective
periods so specified and have been prepared in accordance with GAAP consistently
applied throughout the periods involved except as set forth in the notes thereto
(subject, in the case of any interim financial statements, to normal year-end
adjustments). Except as disclosed in the financial statements listed in Schedule
3.06 or the most recently delivered financial statements delivered in accordance
with Section 5.20, since March 31, 1999, there has been no change in the
financial condition, operations, business, properties or prospects of the
Borrower or any of its Subsidiaries except changes that individually or in the
aggregate would not reasonably be expected to have a Material Adverse Effect.
There is no fact known to the Borrower that could reasonably be expected to have
a Material Adverse Effect that has not been set forth herein or in the financial
statements listed in Schedule 3.06.

         SECTION 3.07. Litigation; Observance of Statutes and Orders.

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

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


REVOLVING CREDIT FACILITY AGREEMENT -- Page 30
<PAGE>   35

Applicable Governmental Authority, which default or violation, individually or
in the aggregate, would reasonably be expected to have a Material Adverse
Effect.

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

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

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

         SECTION 3.11. Compliance with ERISA.

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


REVOLVING CREDIT FACILITY AGREEMENT -- Page 31
<PAGE>   36

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

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

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

         SECTION 3.12. Use of Proceeds; Termination of Existing Credit
Agreements; Margin Regulation. The Borrower will apply the proceeds of the Loans
to refinance existing indebtedness, make acquisitions, for capital expenditures
and for working capital and other general corporate purposes. Without limiting
the generality of the forgoing, the Borrower agrees to use the proceeds of the
first Loans made hereunder and the net proceeds of its initial public offering
consummated in 1999 to repay in full all obligations outstanding in connection
with the following agreements (the "Existing Credit Agreements"):

                  (i) The Advance Term Credit Agreement dated March 16, 1999
         among Borrower, Chase Bank of Texas, National Association, as
         administrative agent, and Wachovia Bank, N. A., as documentation agent;
         and

                  (ii) The Revolving Credit Facility Agreement dated July 13,
         1998 among Borrower, Chase Bank of Texas, National Association, as
         administrative agent, Wachovia Bank, N. A., as documentation agent and
         the lenders named therein.

The Borrower agrees that on the date that the first Loans are made hereunder all
the commitments of the lenders under the Existing Credit Agreements are
terminated and of no further force or effect. No part of the proceeds from the
Loans will be used, directly or indirectly, for the purpose of buying or
carrying any margin stock within the meaning of Regulation U of the Board (12
CFR 221), or for the purpose of buying or carrying or trading in any securities
under such circumstances as to involve the Borrower in a violation of Regulation
X of the Board (12 CFR 224) or to involve any broker or dealer in a violation of
Regulation T of the Board (12 CFR 220). Margin stock does not constitute more
than 5% of the value of the consolidated assets of the


REVOLVING CREDIT FACILITY AGREEMENT -- Page 32
<PAGE>   37

Borrower and its Restricted Subsidiaries and the Borrower does not have any
present intention that margin stock will constitute more than 5% of the value of
such assets. As used in this Section, the terms "margin stock" and "purpose of
buying or carrying" shall have the meanings assigned to them in said Regulation
U.

         SECTION 3.13. Existing Indebtedness. Except as described therein,
Schedule 3.13 sets forth a complete and correct list of all outstanding
Indebtedness of the Borrower and its Restricted Subsidiaries (other than
Indebtedness of Restricted Subsidiaries to the Borrower or to Wholly-Owned
Restricted Subsidiaries) as of June 30, 1999, since which date there has been no
Material change in the amounts, interest rates, sinking funds, installment
payments or maturities of the Indebtedness of the Borrower or its Restricted
Subsidiaries. Neither the Borrower nor any Restricted Subsidiary is in default,
and no waiver of default is currently in effect, in the payment of any principal
or interest on any Indebtedness of the Borrower or such Restricted Subsidiary,
and no event or condition exists with respect to any Indebtedness of the
Borrower or any Restricted Subsidiary the outstanding principal amount of which
exceeds $3,000,000 in the aggregate that would permit (or that with notice or
the lapse of time, or both, would permit) one or more Persons to cause such
Indebtedness to become due and payable before its stated maturity or before its
regularly scheduled dates of payment. To the knowledge of the Responsible
Officers of the Borrower, no event or condition exists with respect to any
Indebtedness of the Borrower or any Restricted Subsidiary that would permit (or
that with notice or the lapse of time, or both, would permit) one or more
Persons to cause such Indebtedness to become due and payable before its stated
maturity or before its regularly scheduled dates of payment.

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

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

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

         SECTION 3.17. Year 2000 Matters. Any programming required to permit the
proper functioning, in and following the year 2000, of the Borrower's and its
Subsidiaries' Material (i) computer systems and (ii) equipment containing
imbedded microchips (including systems and equipment supplied by others or with
which the Borrower's or its Subsidiaries' systems interface)


REVOLVING CREDIT FACILITY AGREEMENT -- Page 33
<PAGE>   38

and the testing of all such systems and equipment, as so reprogrammed, is
expected to be completed by October 31, 1999. The cost to the Borrower and its
Subsidiaries of such reprogramming and testing and of the reasonably foreseeable
consequences of year 2000 to the Borrower and its Subsidiaries (including,
without limitation, reprogramming errors and the failure of others' systems or
equipment) will not result in a Default or a Material Adverse Effect. Except for
such of the reprogramming referred to in the preceding sentence as may be
necessary, the computer and management information systems of the Borrower and
its Subsidiaries are, and with ordinary course upgrading and maintenance, will
continue for the term of this Agreement to be, sufficient to permit the Borrower
and its Subsidiaries to conduct its business without Material Adverse Effect.

ARTICLE 4. CONDITIONS OF LENDING

ARTICLE 5. AFFIRMATIVE AND NEGATIVE COVENANTS

         The Borrower agrees that, so long as any Lender has any Commitment
hereunder or any amount payable hereunder remains unpaid:


REVOLVING CREDIT FACILITY AGREEMENT -- Page 35
<PAGE>   40

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

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

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

         SECTION 5.04. Payment of Taxes. The Borrower will and will cause each
of its Subsidiaries to file all income tax or similar tax returns required to be
filed in any jurisdiction and to pay and discharge all taxes shown to be due and
payable on such returns and all other taxes, assessments, governmental charges,
or levies payable by any of them, to the extent such taxes and assessments have
become due and payable and before they have become delinquent, provided that
neither the Borrower nor any Subsidiary need pay any such tax or assessment if
(i) the amount, applicability or validity thereof is contested by the Borrower
or such Subsidiary on a timely basis in good faith and in appropriate
proceedings, and the Borrower or a Subsidiary has established adequate reserves
therefor in accordance with GAAP on the books of the Borrower or such Subsidiary
or (ii) the nonpayment of all such taxes and assessments in the aggregate would
not reasonably be expected to have a materially adverse effect on the business,
operations, affairs,


REVOLVING CREDIT FACILITY AGREEMENT -- Page 36
<PAGE>   41
financial condition, properties or assets of the Borrower and its Restricted
Subsidiaries taken as a whole.

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

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

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


REVOLVING CREDIT FACILITY AGREEMENT -- Page 37
<PAGE>   42
Article 6 of this Agreement, but contains one or more percentages, amounts or
formulas that is more restrictive or has a shorter grace period than those set
forth herein or is more beneficial to the holder or holders of such other
Indebtedness (and such provision shall be deemed an "Additional Default" only to
the extent that it is more restrictive, has a shorter grace period or is more
beneficial) or (B) is different from the subject matter of the Defaults and
Events of Default contained in Article 6 of this Agreement.

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

         SECTION 5.08. Environmental Matters.

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

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

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


REVOLVING CREDIT FACILITY AGREEMENT -- Page 38
<PAGE>   43

favorable to the Borrower or such Restricted Subsidiary than would be obtainable
in a comparable arm's-length transaction with a Person not an Affiliate.

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

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

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

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

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

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

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

         (b) such Transfer is from


REVOLVING CREDIT FACILITY AGREEMENT -- Page 39
<PAGE>   44

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

                  (ii) the Borrower to a Restricted Subsidiary, or

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

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

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

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

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

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

         SECTION 5.12. Incurrence of Indebtedness. The Borrower will not, and
will not permit any Restricted Subsidiary to, directly or indirectly, create,
incur, assume, guarantee, or otherwise become directly or indirectly liable with
respect to any Indebtedness, unless on the date the Borrower or such Restricted
Subsidiary becomes liable with respect to any such Indebtedness and

immediately after giving effect thereto and to the substantially concurrent
retirement of any other Indebtedness,

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

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

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

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

hereafter acquired, or any income or profits therefrom, or assign or otherwise
convey any right to receive income or profits, except:

obligation it secures (i) shall not, within ninety (90) days after the entry
thereof, have been discharged or execution thereof stayed pending appeal, or
shall not have been discharged within ninety (90) days after the expiration of
any such stay or (ii) exceeds, together with the amounts of all other
obligations secured by attachment or judgment Liens at the time existing in
respect of property of the Borrower and its Restricted Subsidiaries, $5,000,000;

         (e) leases or subleases granted to others, easements, rights-of-way,
restrictions and other similar charges or encumbrances, in each case incidental

Borrower or any of its Restricted Subsidiaries, provided that such Liens do not,
in the aggregate, materially detract from the value of such property;

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

secured by such Lien immediately prior to such extension, renewal or refunding
is not increased or the maturity thereof reduced, (ii) such Lien is not extended
to any other property, and (iii) immediately after such extension, renewal or
refunding no Default or Event of Default would exist and the Borrower would be

respectively; and

         (i) other Liens not otherwise permitted by Subsections (a) through (h)

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

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

         SECTION 5.14. Restricted Payments. The Borrower will not, and will not
permit any of its Restricted Subsidiaries to, declare or make, or incur any

         expenses (including the interest portion of Capital Leases) for the
         Borrower and the Restricted Subsidiaries calculated on a consolidated

Indebtedness outstanding as of such day to the Adjusted EBITDA for the four (4)
fiscal quarters then ended to exceed 3.00 to 1.00.

         (c) Consolidated Net Worth. The Borrower will not permit Consolidated

         respects, the financial position of the companies being reported upon
         and their results of operations and cash flows and have been prepared
         in conformity with GAAP, and that the examination of such accountants
         in connection with such financial statements has been made in
         accordance with generally accepted auditing standards, and that such

believed by it in good faith to be genuine and correct and to have been signed
or sent by the proper Person or Persons. Neither the Administrative Agent nor
any of its directors, officers, employees or agents shall have any
responsibility to the Borrower on account of the failure of or delay in
performance or breach by any Lender of any of its obligations hereunder or any

Agent as provided below, the Administrative Agent may resign at any time by
notifying the Lenders and the Borrower. Upon any such resignation, the Required

no Lender agrees to accept such appointment. If no successor shall have been so
appointed by the Required Lenders, no approval of the Borrower obtained and such

demand, in the amount of its pro rata share (based on its Commitment hereunder
or, if the Total Commitment shall have been terminated, the amount of its
outstanding Loans) of any expenses incurred for the benefit of the Lenders in
its role as Administrative Agent, including reasonable counsel fees and
compensation of agents and employees paid for services rendered on behalf of the
Lenders, which shall not have been reimbursed by the Borrower AND (II) TO
INDEMNIFY AND HOLD HARMLESS THE ADMINISTRATIVE AGENT AND ANY OF ITS DIRECTORS,
OFFICERS, EMPLOYEES OR AGENTS, ON DEMAND, IN THE AMOUNT OF SUCH PRO RATA SHARE,

ANY OF ITS DIRECTORS, OFFICERS, EMPLOYEES OR AGENTS.

         Each Lender acknowledges that it has, independently and without
reliance upon the Administrative Agent or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement

its rights under this Agreement to a Federal Reserve Bank; provided that no such

BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF (I) THE CONSUMMATION OF THE

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

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

         SECTION 8.08. Waivers; Amendment.

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

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan, or waive or excuse any such payment or any part
thereof, or decrease the rate of interest on any Loan, without the prior written
consent of each Lender affected thereby, (ii) increase any Commitment or
decrease the Commitment Fee Percentage or change the date on which the
Commitment Fees are due and payable, or (iii) amend or modify the provisions of
Section 2.13, Section 4.02(e) or Section 8.04(h), the provisions of this Section
or the definition of the "Required Lenders", without the prior written consent
of each Lender; provided further, however, that no such agreement shall amend,
modify or otherwise affect the rights or duties of the Administrative Agent
hereunder without the prior written consent of the Administrative Agent. Each
Lender shall be bound by any waiver, amendment or modification authorized by
this Section and any consent by any Lender pursuant to this Section shall bind
any assignee of its rights and interests hereunder.

         SECTION 8.09. Entire Agreement. THIS AGREEMENT (INCLUDING THE SCHEDULES
AND EXHIBITS HERETO) AND THE FEE LETTERS CONSTITUTE A "LOAN


REVOLVING CREDIT FACILITY AGREEMENT -- Page 59
<PAGE>   64
AGREEMENT" AS DEFINED IN SECTION 26.03(A) OF THE TEXAS BUSINESS AND COMMERCE
CODE, AND REPRESENT THE ENTIRE CONTRACT AMONG THE PARTIES RELATIVE TO THE
SUBJECT MATTER HEREOF AND THEREOF. ANY PREVIOUS AGREEMENT AMONG THE PARTIES WITH
RESPECT TO THE SUBJECT MATTER HEREOF IS SUPERSEDED BY THIS AGREEMENT AND THE FEE
LETTERS. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. NOTHING IN
THIS AGREEMENT, EXPRESSED OR IMPLIED, IS INTENDED TO CONFER UPON ANY PARTY OTHER
THAN THE PARTIES HERETO ANY RIGHTS, REMEDIES, OBLIGATIONS OR LIABILITIES UNDER
OR BY REASON OF THIS AGREEMENT.

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

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

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

         SECTION 8.13. Interest Rate Limitation.

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

         (b) If the amount of interest, together with all Charges, payable for
the account of any Lender in respect of any interest computation period is
reduced pursuant to paragraph (a) of this Section and the amount of interest,
together with all Charges, payable for such Lender's account in respect of any
subsequent interest computation period, computed pursuant to Section 2.06, would
be less than the Maximum Rate, then the amount of interest, together with all
Charges, payable for such Lender's account in respect of such subsequent
interest computation period shall, to the extent permitted by applicable law, be
automatically increased to such Maximum Rate;


REVOLVING CREDIT FACILITY AGREEMENT -- Page 60
<PAGE>   65

provided that at no time shall the aggregate amount by which interest paid for
the account of any Lender has been increased pursuant to this paragraph (b)
exceed the aggregate amount by which interest, together with all Charges, paid
for its account has theretofore been reduced pursuant to paragraph (a) of this
Section.

         (c) No provision of this Agreement shall require the payment or the
collection of interest in excess of the maximum amount permitted by applicable
law. If any excess of interest in such respect is hereby provided for, or shall
be adjudicated to be so provided, in this Agreement or otherwise in connection
with this loan transaction, the provisions of this Section shall govern and
prevail and neither the Borrower nor the sureties, guarantors, successors, or
assigns of the Borrower shall be obligated to pay the excess amount of such
interest or any other excess sum paid for the use, forbearance, or detention of
sums loaned pursuant hereto. In the event any Lender ever receives, collects, or
applies as interest any such sum, such amount which would be in excess of the
maximum amount permitted by applicable law shall be applied as a payment and
reduction of the principal of the Loans; and, if the principal of the Loans has
been paid in full, any remaining excess shall forthwith be paid to the Borrower.
In determining whether or not the interest paid or payable exceeds the Maximum
Rate, the Borrower and each Lender shall, to the extent permitted by applicable
law, (a) characterize any non-principal payment as an expense, fee, or premium
rather than as interest, (b) exclude voluntary prepayments and the effects
thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal
parts the total amount of interest throughout the entire contemplated term of
the Loans so that interest for the entire term does not exceed the Maximum Rate.

         SECTION 8.14. Confidentiality. For the purposes of this Section 8.14,
"Confidential Information" means information delivered to an Agent or a Lender
by or on behalf of the Borrower or any Subsidiary in connection with the
transactions contemplated by or otherwise pursuant to this Agreement that is
proprietary in nature and that was clearly marked or labeled or otherwise
adequately identified when received by an Agent or a Lender as being
confidential information of the Borrower or such Subsidiary, provided that such
term does not include information that (a) was publicly known or otherwise known
to an Agent or a Lender prior to the time of such disclosure, (b) subsequently
becomes publicly known through no act or omission by an Agent or a Lender or any
Person acting on their behalf, (c) otherwise becomes known to an Agent or a
Lender other than through disclosure by the Borrower or any Subsidiary or (d)
constitutes financial statements delivered to you under Section 5.20 that are
otherwise publicly available. Each Agent and each Lender agree that they will
maintain the confidentiality of such Confidential Information in accordance with
procedures adopted by them in good faith to protect confidential information of
third parties delivered to them, provided that an Agent or a Lender may deliver
or disclose Confidential Information to (i) its directors, officers, employees,
agents, attorneys and affiliates (to the extent such disclosure reasonably
relates to the administration of this Agreement), (ii) its financial advisors
and other professional advisors who agree to hold confidential the Confidential
Information substantially in accordance with the terms of this Section 8.14,
(iii) any other Agent or Lender, (iv) any Transferee (if such Person has agreed
in writing prior to its receipt of such Confidential Information to be bound by
the provisions of this Section


REVOLVING CREDIT FACILITY AGREEMENT -- Page 61
<PAGE>   66

8.14), (v) any Person from which it offers to purchase any Security of the
Borrower or a Subsidiary (if such Person has agreed in writing prior to its
receipt of such Confidential Information to be bound by the provisions of this
Section 8.14), (vi) any federal or state regulatory authority having
jurisdiction over it, (vii) any nationally recognized rating agency that
requires access to information about its investment portfolio, or (viii) any
other Person to which such delivery or disclosure may be necessary or
appropriate (w) to effect compliance with any law, rule, regulation or order
applicable to it, (x) in response to any subpoena or other legal process, (y) in
connection with any litigation to which it is a party or (z) if an Event of
Default has occurred and is continuing, to the extent an Agent or a Lender may
reasonably determine such delivery and disclosure to be necessary or appropriate
in the enforcement or for the protection of the rights and remedies under this
Agreement.

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

         SECTION 8.16. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.
