ITEM 1. BUSINESS
 
GENERAL
 
    In 1994, O.Y.L. Industries Berhad ("OYL"), a member of the Hong Leong Group
Malaysia ("Hong Leong"), one of Malaysia's leading manufacturers and exporters
of commercial and industrial air conditioners, refrigerators, freezers and
electrical components, purchased all the outstanding stock of the Company (then
named SnyderGeneral Corporation) for approximately $420 million, including the
assumption of debt (the "OYL Acquisition"). As part of the funding, OYL made a
cash investment of $170 million, applied both to purchase the prior owner's
interest and to restructure the Company's debt. The Company was then renamed
AAF-McQuay Inc. OYL is a subsidiary of Hume Industries Malaysia Berhad ("Hume").
Hume, like OYL, is a publicly traded Malaysian company controlled by Hong Leong.
Mr. Quek Leng Chan is Hong Leong's controlling shareholder.
 
    The Company is a leading worldwide manufacturer and marketer of commercial
air conditioning and air filtration products and systems primarily for
commercial, institutional and industrial customers. The Company believes that it
is the leading global manufacturer of air filtration products for nonvehicular
applications and is a major participant in the global commercial HVAC market. In
addition, in December 1995, the Company entered the industrial refrigeration
business through the acquisition of J&E Hall, the United Kingdom's leading
integrated provider of industrial refrigeration and freezing equipment. The
Company maintains production facilities in nine countries and its products are
sold in over 80 countries. The Company believes that its geographic and product
diversification makes it less susceptible to an economic downturn in any
particular market or region.
 
    The Company believes its affiliation with Hong Leong, which has a
significant Asian presence, substantially improves the Company's financial and
operating flexibility and access to Asian markets. The Company has also expanded
into other new markets outside Asia, such as Latin America, where demand has
increased and the markets remain fragmented. In addition, the Company seeks to
expand its product lines through research and development and seeks to pursue
strategic technology joint ventures and acquisitions. Consistent with this
strategy, the Company acquired the industrial refrigeration business of J&E
Hall. The acquisition of J&E Hall expanded the Company's product offerings and
also accelerated its development of the single screw compressors that both the
Company and J&E Hall had been developing for several years. The Company believes
that single screw chillers, rather than twin screw chillers produced by a number
of its competitors in the commercial HVAC and industrial refrigeration markets,
provide certain competitive advantages, including improvements in efficiency and
cost, lower service requirements and noise reduction.
 
    The Company's Commercial Air Conditioning and Refrigeration Group engages in
the manufacture, sale, service and distribution of HVAC equipment, industrial
refrigeration and freezing products and systems. Products include chillers,
applied air handling systems, terminal air conditioning systems, fans,
industrial refrigerators and freezers, service and parts. The Company's
commercial air conditioning equipment is sold primarily under the McQuay
- -Registered Trademark- and BarryBlower -Registered Trademark- brand names and
has been installed in many prominent facilities around the world, including the
Queen Elizabeth II, the Chrysler Technical Center in Detroit, the Jakarta Stock
Exchange in Indonesia, the Nestle^ Headquarters in Switzerland and the Georgia
Dome in Atlanta. The Company's Commercial Air Conditioning and Refrigeration
Group is also the leading integrated supplier of industrial refrigeration and
freezing products and systems in the United Kingdom and is among the three
largest suppliers of industrial contact plate ("fast") freezers in the world.
Industrial refrigeration products and systems are sold under the "J&E Hall"
brand name and freezers are sold under the "Jackstone" brand name. In connection
with its refrigeration business, the Commercial Air Conditioning and
Refrigeration Group also manufactures a line of single screw compressors which
are sold under the "HallScrew" brand name. In addition to establishing an
important presence in the global industrial refrigeration industry, the
acquisition of J&E Hall provided the Company with access to J&E Hall's single
screw compressor technology which has expanded the single screw chiller product
line.
 
    The Company's Filtration Products Group engages in the manufacture, sale and
distribution of air filtration products and systems, including air filtration
equipment, air pollution control products and systems, machinery filtration and
acoustic systems and replacement filters. The Company's products,
 
                                       3
<PAGE>
including replacement filters, are sold globally under the AmericanAirFilter TM
and AAF -Registered Trademark- brand names and under private label. The
Company's filtration products are sold worldwide to commercial, institutional
and industrial customers as well as to retailers for residential use. The
Filtration Products Group's largest customers include Shinwa Corporation,
Wal-Mart Stores, Inc., Ace Hardware Corp., Asea Brown Boveri ("ABB"), European
Gas Turbines, Westinghouse Electric Corp. and Solar Gas Turbines.
 
COMMERCIAL AIR CONDITIONING AND REFRIGERATION GROUP
 
    The Company, through the Commercial Air Conditioning and Refrigeration
Group, is a worldwide leader in the design, manufacture, sale and service of
HVAC equipment principally for the commercial, industrial and institutional
markets. In the United States, the Company believes that its share of the
commercial air conditioning market which it serves is approximately 10%. The
Company's products are sold primarily under the widely recognized McQuay
- -Registered Trademark- and BarryBlower -Registered Trademark-brand names and
services are marketed under the McQuayService TM name. The Company's broad range
of standard and custom products and services fulfill the HVAC requirements of
most building types and sizes and offer multiple solutions to a variety of HVAC
needs. The Company markets its commercial HVAC equipment principally to building
contractors, architects, consulting engineers, building developers and building
owners. In addition, the Company manufactures, sells and services industrial
refrigeration and freezing equipment under the J&E Hall brand names including
J&E Hall, Thermotank, and Jackstone. Principle customers are in the food and
beverage, chemical and naval and maritime industries.
 
    The Company's Commercial Air Conditioning and Refrigeration products are
divided among the following business units: (i) chiller products, (ii) applied
air handling systems, (iii) terminal air conditioning systems, (iv) fans and (v)
industrial refrigeration.
 
    CHILLER PRODUCTS.  The Company's chiller products include centrifugal,
screw, absorption and reciprocating chillers, condensing units and air cooled
condensers, all of which frequently contain sophisticated control systems. These
products are normally engineered and assembled to meet specific design criteria
for a wide range of commercial, institutional and industrial applications.
Typical applications are large square footage buildings which require integrated
HVAC systems ranging in capacity from 10 to over 2,300 tons (the cooling
capacity of air conditioning units is measured in tons; one ton being equivalent
to 12,000 BTUs and generally adequate to air condition approximately 500 square
feet of space). The Company is also the only HVAC manufacturer to offer a broad
line of dual compressor centrifugal chillers which offer improved energy
efficiency because of their unique part-load capability. The dual compressor
centrifugal chiller provides the Company with additional competitive advantages
by virtue of its small footprint, built-in redundancy, and its utilization of
HFC-134a (non CFC) refrigerant. In 1995, the Company began manufacturing gas
absorption chillers which offer an alternative to building owners faced with CFC
phaseout since these chillers operate with water vapor as the refrigerant.
 
    Under the trade name McQuayServiceTM, the Company services both its own and
its competitors' products and systems and provides start-up assistance, warranty
support, full aftermarket service, replacement parts and chiller retrofit
services. The Company's service operations are conducted primarily in North
America through 20 field offices and employ approximately 310 personnel. In
addition to providing a non-cyclical source of revenues, the Company's service
and parts business provides access to the growing replacement and retrofit
markets.
 
    APPLIED AIR HANDLING SYSTEMS.  Applied air handling systems include indoor
and roof mounted air handling units, packaged rooftop systems, self-contained
systems and coils with capacities up to 135 tons that are generally mounted on
the roof of a building, in ceilings and/or duct work, or installed on each floor
of a multi-story building. These units generally combine heating and cooling
capabilities in a single or self-contained configuration. The Company has
recently developed a new line of advanced technology air handlers which combine
European and North American designs to meet the market's growing demand for
quiet, reliable, high quality air handlers in response to demand for improved
indoor air quality.
 
    TERMINAL AIR CONDITIONING SYSTEMS.  Terminal air conditioning systems
consist of HVAC units that provide heating and cooling for a defined space on a
"localized" basis. They include fan-coil units, water source heat pumps,
packaged terminal air conditioners and heat pumps, unit ventilators and
mini-split systems. Capacities of individual units are less than 20 tons and
typically include electronic controls. Typical applications include facilities
where air conditioning is required on a "room-by-room" basis such as hotels/
 
                                       4
<PAGE>
motels, condominiums, schools and office buildings. Within the United States,
the Company believes that it is a leading manufacturer of water source heat
pumps and unit ventilators. The large installed base is expected to provide
significant replacement and service opportunities. The Company recently
introduced a new line of console water source heat pumps which are more
efficient and feature sophisticated electronic controls.
 
    FANS.  The Company manufactures and sells a wide range of commercial and
industrial fans which are used in HVAC and industrial applications. The fans are
sold under the BarryBlower-Registered Trademark- brand name.
 
    INDUSTRIAL REFRIGERATION.  The Company manufactures, sells and services
industrial refrigeration and freezing equipment under several well known J&E
Hall brand names, including J&E Hall, Thermotank, and Jackstone. The principal
customers for industrial refrigeration products are concentrated in the food and
meat processing, dairy, brewing and beverage (soft and alcoholic), chemical,
petrochemical, pharmaceutical, naval and merchant marine industries. The
principal customers for industrial freezers are in the food industry generally
and particularly the seafood industry. The Company manufactures industrial
refrigeration and freezer products through J&E Hall's U.K. production
facilities. In fiscal year 1997, the Company acquired Coulstock & Place
Engineering Co. Ltd., a motor rewind specialist providing support for the
Compressor business.

COMPETITION
 
    GENERAL.  The commercial HVAC and refrigeration and air filtration business
segments are highly competitive. In the commercial HVAC industry, the principal
methods of competition are lead time, product performance, feature availability,
energy efficiency, price and service. In the refrigeration industry, competitive
factors include price, quality and a vertically integrated approach of supplying
products. In the air filtration business, participants generally compete on the
basis of service, price, quality, reliability, efficiency, conditions of sale
and range of product offering. Certain portions of these markets are also very
fragmented, both geographically and by product line. The Company believes its
competitive position is strengthened in those international markets in which it
has both a manufacturing and a marketing presence and that it has a competitive
advantage through its affiliation with Hong Leong and OYL in gaining access to
certain markets where barriers exist for non-local companies.
 
    COMMERCIAL AIR CONDITIONING AND REFRIGERATION GROUP.  International markets
for commercial HVAC products are competitive and fragmented along geographic and
product lines. On a global basis, the Company's primary competitors across the
full range of its HVAC product offerings are Carrier Corporation (a subsidiary
of United Technologies Corporation), The Trane Company (a division of American
Standard, Inc.) and York International Corporation. Outside North America, the
Company also competes with numerous European and Japanese companies. Competition
in the global industrial refrigeration and freezer business is fragmented,
consisting of a limited number of large companies and a significant number of
local companies. The Company believes that price and quality in addition to a
vertically integrated approach to supplying products and systems are significant
competitive factors in selling industrial refrigeration and freezer products.
 
    FILTRATION PRODUCTS GROUP.  Competition in the air filtration products and
systems, air pollution control equipment and systems and MFAS businesses is very
fragmented. Globally, the Company competes with many companies along each

    The Company's research and development programs are involved in creating new
products, enhancing and redesigning existing equipment and systems to reduce
manufacturing costs and increasing product efficiency. The Company spent
approximately $10.6 million, $8.2 million, and $4.3 million during the 12 months
ended June 30, 1997, June 30, 1996 and the six months ended July 1, 1995,
respectively, for research and development.
 
    A significant focus of the Company's research and development efforts since
1988 has been to develop and extend its range of water-cooled and air-cooled
water chillers using advanced single screw compressor technology. The Company
introduced its first single screw air conditioning product in 1994 and has
continued to expand its offerings during 1997. It expects further screw air
conditioning product introductions during fiscal year 1998. Single screw
compressor technology will continue to be important elements of research and
development programs in the Commercial Air Conditioning and Refrigeration Group.
J&E Hall has been marketing industrial refrigeration product using single screw
compressor technology since 1978.
 
    The Company has developed and is now producing the next generation of air
handlers which is highly energy and sound efficient. The product is available in
a variety of configurations and material options. The Company expects this
family of product to meet the growing market for quiet, high quality air
handlers.
 
    Additionally, the Company has introduced a new range of air cleaners; a new
extended surface pleated filter that exceeds the standards proposed in ASHRAE
62-1989R; a variety of replacement filters treated with antimicrobial agents
that inhibit the growth of various microbial contaminants on the filter media;
and a range of self cleaning filters for gas turbines.
 
PATENTS AND TRADEMARKS
 
    The Company holds numerous patents related to the design and use of its
equipment and systems that are considered important to the overall conduct of
its business. The Company's policy is to maintain patent protection for as many
of its new products as possible. The Company believes that certain of its
patents are
 
                                       8
<PAGE>
important to distinguish the Company's equipment and systems from those of its
competitors; however, the Company does not consider any particular patent, or
any groups of related patents, essential to its operations. The Company believes
that its rights in its patents are adequately protected.
 
    The Company owns several registered trademarks and operates under certain
trade names that are important in the marketing of its products, including
AmericanAirFilter TM, AAF-Registered Trademark-, McQuay-Registered Trademark-,
BarryBlower-Registered Trademark-, HermanNelson-Registered Trademark-,
Thermotank, Jackstone and Beth. The Company believes that its rights to use
tradenames and trademarks are adequately protected.
 
EMPLOYEES
 
    As of June 30, 1997 the Company employed approximately 7,000 employees
worldwide, with approximately 4,400 persons employed in the United States and
2,600 employed in non U.S. locations. The Company has a total of 19 labor union
bargaining agreements, covering approximately 2,300 employees in the United
States and Canada, of which 4 agreements, covering 1,100 employees, will expire
in fiscal year 1998. The Company currently believes that it will be able to
obtain new labor agreements without interruption of work when these agreements
expire. The Company considers its relations with its employees to be good.
 
ENVIRONMENTAL REGULATIONS
 
    Environmental laws that affect or could affect the Company's domestic
operations include, among others, the Clean Air Act, the Clean Water Act, the
Resource Conservation and Recovery Act, the Occupational Safety and Health Act,
the National Environmental Policy Act, the Toxic Substances Control Act, any
regulations promulgated under these acts and various other federal, state and
local laws and regulations governing environmental matters. The Company's
foreign operations are also subject to various environmental statutes and
regulations.
 
    Some of the refrigerants used in HVAC equipment manufactured by the Company
are regulated under international agreements and domestic and foreign laws and
regulations governing stratospheric ozone depleting chemicals.
 
    In 1987, the United States became a signatory to the Montreal Protocol. The
Montreal Protocol has been amended several times since 1987, including in 1990
(the "London Amendments"), in 1992 (the "Copenhagen Amendments"), and in 1995.
Over 100 countries are signatories to the Montreal Protocol and the London
Amendments. More than 40 countries (including the United States) have also
agreed to abide by the Montreal Protocol as amended by the Copenhagen
Amendments.
 
    Under the Montreal Protocol, as amended, consumption (defined as production
plus imports minus exports) of CFCs by participating industrialized companies is
banned, with limited exceptions, as of January 1, 1996. Additionally, the
Montreal Protocol places a cap on the consumption of HCFCs beginning on January
1, 1996 and mandates a gradual phaseout culminating in 2020, for participating
industrialized countries, with a ten-year service tail exemption allowing
industrialized countries to supply old equipment with HCFCs during this period.
In addition, certain countries, not including the United States, declared during
December 1995 that they would take all appropriate measures to limit the use of
HCFCs as soon as possible.
 
    The federal Clean Air Act Amendments of 1990 establish minimum statutory
timetables for the phaseout of consumption of ozone-depleting chemicals in the
United States, and authorize the EPA to establish regulatory timetables which
meet and exceed those set forth in the Montreal Protocol, as amended. Pursuant
to that authority, the EPA has adopted regulations mandating, among other things
and with limited exceptions, (a) a total ban on the consumption of CFCs by
January 1, 1996 (b) a prohibition on the consumption of HCFC-142b and HCFC-22 (a
refrigerant used in some equipment manufactured by the Company) for new
equipment beginning on January 1, 2010, (c) a ban on consumption of HCFC-142b
and HCFC-22 for use in old equipment beginning on January 1, 2020, and (d) a
phaseout of other HCFCs commencing in 2015.
 
    The manner in which the other signatories to the Montreal Protocol implement
its requirements and regulate ozone-depleting refrigerants could differ from the
approach and timetables adopted in the United States.
 
                                       9
<PAGE>
    With respect to the ban on consumption of CFCs (which began January 1,
1996), the Company has redesigned its large cooling capacity central station
system HVAC equipment to utilize hydrofluorocarbon-134a ("HFC-134a"), a
non-chlorinated refrigerant that is believed to be harmless to the ozone layer
and is not scheduled for elimination pursuant to the Montreal Protocol.
 
    Substantially all major manufacturers of HVAC products, including the
Company, produce HVAC equipment for smaller cooling capacity applications that
utilize HCFC-22. The Company (and its competitors) must develop substitute
refrigerants for use in HVAC products that currently use HCFC-22 prior to the
phaseout of HCFC-22. Presently, the EPA has identified several refrigerants that
it considers acceptable HCFC-22 substitutes for certain uses applicable to some
of the Company's products. The Company is utilizing one such substitute in some
of its equipment sold in Europe and is evaluating redesigned equipment capable
of utilizing other acceptable substitutes.

ITEM 3. LEGAL PROCEEDINGS
 
    ENVIRONMENTAL PROCEEDINGS.
 
    CERCLA and other federal, state, local and foreign acts may subject the
Company to liability for the release of pollutants into the environment. CERCLA
imposes liability for the cleanup of releases of hazardous substances from a
facility on four classes of persons: the current owner and operator of the
facility, the owner and operator at the time the hazardous substances were
disposed of at the facility, waste generators that sent their wastes to the
facility, and transporters of waste who selected the facility as a disposal
site. Liability under various environmental statutes, including CERCLA, may be
imposed jointly and severally and regardless of fault.
 
    CERCLA imposes potential liability on the Company for remediating
contamination arising from the Company's past and present operations and from
former operations by other entities at sites later acquired
 
                                       12
<PAGE>
and now owned by the Company. Many of the Company's facilities have operated for
many years, and substances which are or might be considered hazardous were
generated, used, and disposed of at some locations, which will require
remediation. The Company has been, and in the future could be, held responsible
for environmental liabilities resulting from former operations of other entities
at facilities now owned by the Company. In addition, the Company has agreed to
indemnify parties to whom it has sold facilities for certain environmental
liabilities arising from acts occurring before the dates those facilities were
transferred.
 
    It is possible that environmental liabilities in addition to those described
below may arise in the future. The precise costs associated with such
liabilities are difficult to predict at this time.
 
    In 1988, the California Department of Health Services issued a Remedial
Action Order naming the Company and others as respondents in connection with
soil and groundwater contamination in the vicinity of a manufacturing facility
located in Visalia, California that had been owned and operated by the Company's
predecessor, McQuay, Inc., from 1961 to 1973. The Company entered into a
settlement agreement with the other respondents under which the Company, among
other things, agreed to be solely responsible for the remaining cleanup of the
site. As of June 30, 1997 the Company had incurred over $10.5 million in
expenses including cleanup costs and attorney's fees. The Company currently
estimates cleanup costs through fiscal year 2007 to be approximately $6.8
million, of which $1.2 million is expected to be incurred in fiscal year 1998
and $700,000 is expected to be incurred in fiscal year 1999. In addition, the
Company settled a suit brought by the State of California seeking to recover the
state's existing and future oversight costs for the cleanup at the Visalia site.
The Company agreed to pay approximately $375,000 of the state's existing
oversight costs and to pay future oversight costs estimated by the state to
total $286,334 through 2005. The Company also has litigation pending against
several of its insurers seeking coverage under various insurance policies with
respect to the Visalia site. The Company has recovered approximately $11 million
from a number of these insurance carriers. See Note 12 to the Consolidated
Financial Statements.
 
    On April 20, 1989, the Company and the North Carolina Department of
Environment, Health and Natural Resources ("DEHNR") entered into an
Administrative Order of Consent (the "Order"), which related to the Company's
former facility located in Wilmington, North Carolina. The Order was concerned
with the remediation of two separate accidental spills of 1, 1, 1
trichloroethane which occurred at this facility on November 18, 1983, and on
July 24, 1987. The Order provided that the area of residual contamination at the
site is a hazardous waste management unit subject to closure requirements under
the Resource Conservation & Recovery Act. This Order has been vacated and the
Company is trying to negotiate a new agreement for cleanup with DEHNR. Pursuant
to the terms of the sales agreement between the Company and the current owner of
the site, the Company is obligated to undertake remediation of the site at its
sole expense. The Company currently estimates that there will be additional
costs of $5.3 million through fiscal year 2007, of which $1.2 million is
expected to be incurred in fiscal year 1998 and $1.3 million is expected to be
incurred in fiscal year 1999. The primary insurance carrier has paid the limits
of its policy ($200,000). The Company is now in litigation with its excess
insurer. The Court granted the carrier summary judgment on the issue of
coverage, the Company appealed and the appeals court reversed the lower court's
ruling. The case is set for trial in November 1997. The insurer recently filed
another summary judgment motion. See Note 12 to the Consolidated Financial
Statements.
 
    In March 1994, contamination was found in wetlands, soil and groundwater at
the Company's Scottsboro, Alabama manufacturing facility. The Company purchased
the facility from Halstead Industries in 1984. The Alabama Department of
Environmental Management has required investigation and cleanup. The Company
made a claim for indemnification from Halstead Industries, which denied
responsibility. The Company has filed suit against Halstead Industries and is
pursuing recoveries through the legal system. The Company currently estimates
that there will be additional costs of $5.0 million through 2007, of which $2.4
million is expected to be incurred in fiscal year 1998 and $0.3 million is
expected to be incurred in fiscal year 1999.
 
    The Company has discovered contaminants in the soil and/or groundwater at
certain of its other manufacturing facilities. Based upon preliminary estimates
prepared by the Company's environmental consultants, the Company currently
estimates that there will be additional costs at these sites of $5.4 million
through 2007.
 
                                       13
<PAGE>
    Based on preliminary estimates prepared by the Company's environmental
consultants, the Company currently estimates that expenditures for remediation
of all sites described above will be in the aggregate approximately $7.4
million, $2.9 million and $2.4 million in fiscal years 1998, 1999 and 2000,
respectively.
 
    Along with multiple other parties, the Company has been identified as a
potentially responsible party under CERCLA and analogous state laws at numerous
other sites, usually as a generator of wastes which were disposed of at the
site. While CERCLA imposes joint and several liability on responsible parties,
liability at each site is likely to be apportioned among such parties. However,
the Company does not believe that its potential liability at these sites will
have a material adverse effect on the Company's financial condition or results
of operations.
 
    IRS AUDIT.
 
    The Internal Revenue Service (the "IRS") is currently conducting an
examination of the Company's Federal income tax returns for its fiscal years
ended 1987, 1988, 1989, and 1990 and has raised various issues with respect to
certain positions taken by the Company on those returns. The IRS has issued a
revenue agent's report asserting a proposed tax deficiency and the amount of the
proposed deficiency may exceed the amount the Company provided for the
resolution of the tax examination in its financial statements. However, the
Company intends to contest vigorously any proposed deficiency. Moreover, the
Company believes, after having discussed with its tax counsel and advisors the
issues raised by the IRS, that the Company has made adequate provision in
respect of any additional tax liability that the Company may ultimately incur.
See Note 12 to Consolidated Financial Statements.
 
    In March 1995, the Internal Revenue Service opened an examination of the
Predecessor Company's tax returns for the years ending in 1991, 1992, 1993 and
1994. Other than issues originating in earlier years which would also affect
these years, there have been no material adjustments proposed during this
examination
 
    INDEMNIFICATION.
 
    Under the terms of the stock purchase agreement with OYL, prior owners of
the Company provided certain indemnifications to the Company, including an
indemnification for certain tax and environmental matters. The indemnification
is available for aggregate claims (net of recoveries) over $5.8 million and
subject to a ceiling of $18.0 million over the initial $5.8 million deductible.
Claims for indemnified losses can be made for up to five years after the
acquisition date of May 2, 1994.
 
    MISCELLANEOUS.
 
    The Company is involved in various other lawsuits arising out of the conduct
of its business. The Company believes that the outcome of any such pending
claims or proceedings will not have a material adverse effect upon its business
or financial condition. The Company maintains various insurance policies
regarding many of such matters, including general liability and property damage
insurance, as well as product liability, workers' compensation and other
policies, which it believes provide adequate coverage for its operations.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
    On April 28, 1997, the sole shareholder elected the following persons as
members of the Board of Directors of the Company to serve until the next annual
meeting of the stockholder: Quek Leng Chan, Joseph B. Hunter, Gerald L. Boehrs,
Roger Tan Kim Hock, Ho Nyuk Choy, Lin Wan Min and Michael J. Christopher.

ITEM 6. SELECTED FINANCIAL DATA
 
    The following table sets forth selected consolidated historical financial
data of the Company (i) prior to the OYL Acquisition (the "Predecessor
Company"), for the fiscal years ended December 31, 1992 and 1993 and for the
period from January 2 to May 1, 1994 and (ii) after the OYL Acquisition (the
"Successor Company") for the period from May 2 to December 31, 1994, the six
months ended July 1, 1995, and the fiscal years ended June 30, 1996 and June 30,
1997. In 1995 the Company changed its fiscal year end from the Saturday closest
to December 31 to the Saturday closest to June 30 to coincide with OYL's fiscal
year. For clarity of presentation in the consolidated financial statements, all
full fiscal years are shown to begin on January 1 and end on December 31, or to
begin on July 1 and end on June 30. For the periods presented on a basis other
than a full fiscal year, actual period end dates are used.
 
    The table should be read in conjunction with "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the Consolidated
Financial Statements and the related Notes included herein.

                 FOOTNOTES TO TABLE OF SELECTED FINANCIAL DATA
 
(a) The Predecessor Company was taxed as an "S" corporation under the Internal
    Revenue Code. Thus the Predecessor Company's income (loss) was included in
    the taxable income (loss) reported by its stockholders and the Company
    incurred no U.S. Federal income tax expense (benefit) and did not recognize
    certain state income tax expense (benefit). The Predecessor Company's
    subsidiaries (with the exception of AAF-McQuay Holdings, Inc.) were not "S"
    corporations and thus incurred income tax expense (benefit) with respect to
    their taxable income (loss). The Predecessor Company historically paid
    dividends or otherwise distributed amounts to its stockholders to pay taxes
    owed as a result of the Predecessor Company's "S" corporation status.
    Substantially all of the cash dividends were for the payment of such taxes.
    Effective with the OYL Acquisition, the Company terminated its "S"
    corporation status and thereafter computed its income tax expense (benefit)
    with respect to the Company's consolidated income (loss).
 
(b) Other income for the year ended December 31, 1992 primarily reflects the
    receipt of a cash settlement, net of directly related legal expenses,
    resulting from an agreement settling a lawsuit.
 
(c) In December 1990, the FASB issued SFAS No. 106, "Employers' Accounting for
    Postretirement Benefits Other Than Pensions." This statement requires
    postretirement benefits other than pensions, principally health care
    benefits, to be recognized ratably over employee service periods. The
    Predecessor Company's practice was to recognize postretirement benefits
    other than pensions on a cash basis. Effective at the beginning of the
    fiscal year ended December 31, 1992 the Predecessor Company adopted this new
    accounting standard for both domestic and foreign plans and recognized the
    transitional obligation of approximately $4.9 million (net of tax benefits
    of $340,000). Postretirement benefit costs were not restated for prior
    periods.
 
(d) In February 1992, the FASB issued SFAS No. 109, "Accounting for Income
    Taxes." This statement was adopted by the Predecessor Company for the year
    ended December 31, 1993 thereby changing its method of accounting for income
    taxes from the deferred method to the liability method, which resulted in a
    cumulative effect charge of $1.0 million primarily related to deferred taxes
    in foreign countries.
 
(e) The Predecessor Company recorded compensation charges in the period ending
    May 1, 1994 totaling $8.8 million ($2.2 million for employment agreements,
    $.7 million for stock options and $5.9 million for warrants). These charges
    were triggered based upon a change in control or sale of the Predecessor
    Company; and therefore , are directly attributable to the OYL Acquisition.
    The related agreements terminated with the OYL Acquisition.
 
(f) During 1995, the Company changed the reporting of its fiscal year end from
    the Saturday closest to December 31 to the Saturday closest to June 30.
    Through December 31, 1994 certain foreign subsidiaries reported on fiscal
    periods which ended one month prior to the Company's or Predecessor
    Company's period-end. During the six month period ended July 1, 1995, the
    closing date for the foreign subsidiaries was changed to reflect the
    Company's current closing period. As a result, the July 1, 1995 financial
    statements include the financial results of these foreign subsidiaries from
    December 1, 1994 through July 1, 1995. The estimated impact on sales and
    operating income for the six month period ended July 1, 1995, was an
    increase in sales and operating income of $19.1 million and $0.7 million,
    respectively.
 
(g) During the year ended June 30, 1996 the Company completed a refinancing of
    its debt. As part of this refinancing the Company used some of the proceeds
    from the offering to repay long-term debt. As a result, the Company recorded
    an extraordinary item of $1.6 million ($2.7 million net of $1.1 million tax
    benefit) relating to unamortized debt issuance cost.
 
(h) EBITDA represents income (loss) before extraordinary item, cumulative effect
    of accounting change, interest expense, income tax expense, and depreciation
    and amortization. Adjusted EBITDA excludes $35.2 million related to
    potential environmental liabilities for the period ended December 31, 1993.
    The Company has included information concerning EBITDA and Adjusted EBITDA
    as it is relevant for debt covenant analysis and because it is used by
    certain investors as a measure of the Company's ability to service its debt.
    Neither EBITDA nor Adjusted EBITDA should be used as an alternative to, or
    be construed as more meaningful than, operating income or cash flow from
    operations as an

    the OYL acquisition as if it had occured on January 1, 1994) results for the
    six months ended June 30, 1994 are: net sales of $343,850, cost of sales of
    $247,572, operating income of $2,688, interest expense of $16,736, other
    expense of $905, an income tax benefit of $1,954 and a pro forma net loss of

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
    In 1995, the Company changed its fiscal year end from the Saturday closest
to December 31 to the Saturday closest to June 30 to coincide with OYL's fiscal
year. The results of operations have been combined for the unaudited six months
ended December 31, 1994 with the six months ended July 1, 1995 ("Comparable
Period ended July 1, 1995") to allow for the discussion and analysis of
comparable periods. The Company has not provided a discussion of its transition
period (January 1, 1995 to July 1, 1995) as compared to the comparable period in
the prior year. The Company believes that discussion of this period is not
material since the six month period is included in what the Company believes is
a more meaningful discussion comparing the operating results of the 12 month
period ended July 1, 1995. The Company believes that the discussion and the
analysis of the trends for the 12 month period comparison would not be
substantially different than a separate discussion of the six month periods and
there were no significant events that have occurred during the 12 month period
that would have significantly affected the results of either of the six month
periods versus the corresponding 12 month period. The following should be read
in conjunction with the "Selected Financial Data" and the Consolidated Financial
Statements and the Notes thereto. For clarity of presentation, all full fiscal
years are shown to begin on July 1 and end on June 30.
 
    The following table sets forth the major components of the consolidated
results of operations of the Company for the three years ended June 30, 1997
(dollars in thousands):

1997 COMPARED TO 1996
 
CONSOLIDATED
 
    Consolidated net sales were $947.9 million for the fiscal year ended June
30, 1997. This represents an increase in net sales of $46.5 million, or 5.2%,
from $901.4 million for the fiscal year ended June 30, 1996. Income from
operations was $40.6 million or 4.3% of net sales versus $56.7 million or 6.3%
of net sales for fiscal years 1997 and 1996, respectively. The Company's ongoing
implementation of certain cost improvement and strategic initiatives, in both
the Commercial Air Conditioning and Refrigeration Group and Filtration Products
Group, has unfavorably impacted operating income during the year ended June 30,
1997. The implementation of these initiatives has resulted in extended delivery
times for some products and higher than anticipated manufacturing costs and
operating expenses. These strategic initiatives involve the integration and
relocation of certain product manufacturing lines, opening operations in Asia,
start up of new products, implementation of new software systems and the
consolidation of certain field sales'
 
                                       19

offices. In spite of the higher than anticipated transition costs, the Company
remains committed to these strategic initiatives in order to realize the
expected benefits.

COMMERCIAL AIR CONDITIONING AND REFRIGERATION GROUP
 
    NET SALES.  Group net sales were $597.2 million in fiscal year 1997, an
increase of $30.4 million, or 5.4%, from $566.8 million in fiscal year 1996.
 
    North American sales increased 3.5% compared to the prior year. The sales
increase was primarily the result of certain chiller, rooftop and terminal
product sales increases. Air and water cooled chiller product sales increased
7.6% resulting from continued acceptance of products utilizing the single screw
technology and export sales increases, largely to Asia. Rooftop product sales
volume increased 9.2% attributable to strong market demand and gains in market
share. Terminal Products market share also grew yielding sales increases of
19.2% over the previous year. These North American sales increases were
substantially offset by the fiscal year 1997 decrease in absorption chiller
sales versus prior year sales. Absorption chiller sales declined over 60%
primarily related to the reduction in the number of natural gas rebate and
incentive programs offered by utility companies.
 
    Fiscal year 1997 European subsidiary sales increased 10.3%. Refrigeration
sales increased approximately $30 million which is principally the result of
inclusion of only a partial year of sales in fiscal year 1996 due to the mid
year acquisition of J&E Hall. European commercial air conditioning sales
decreased 14.3% in fiscal year 1997 as compared to 1996 due to soft market
demand for chiller and air handling products in addition to several large jobs
in the prior year that were not repeated. Also, the strengthening U.S. dollar
unfavorably impacted sales by approximately $4 million in fiscal year 1997 due
to currency translation.
 
    OPERATING INCOME EXCLUDING AMORTIZATION.  Operating income excluding
amortization was $23.3 million in fiscal year 1997, a decrease of $13.9 million,
or 37.3%, from $37.2 million in fiscal year 1996. Operating income excluding
amortization as a percent of sales decreased from 6.6% to 3.9%. The gross margin
rate decreased 1.1 percentage points from the prior year rate due primarily to
lower terminal product prices, the inclusion of several large high margin jobs
in the prior year which were not repeated and substantially increased air
handling product manufacturing costs due to new product start-up efforts.
Selling, General & Administrative expense ("SG&A") as a percentage of sales
increased 1.6 percentage points in fiscal year 1997 compared to fiscal year
1996. SG&A increases relate to volume increases, higher warranty costs, an
overall increased cost base due to the strengthening of the management
organization and increases in research and development expenses primarily in
single screw compressor technology.
 
    The contribution to operating income from sales volume increases was offset
by several significant operating conditions during fiscal year 1997.
 
    - NEW PRODUCT INTRODUCTION In fiscal year 1997, air handling operating
      income decreased $6.7 million compared to the prior year. The introduction
      of a new air handling product resulted in substantial manufacturing start
      up costs and other expenses. However, market acceptance of this product
      has been excellent with a backlog of several million dollars at the end of
      fiscal year 1997. The
 
                                       20
<PAGE>
      improvement actions implemented by the Company in fiscal year 1997 are not
      anticipated to yield full benefits immediately. While many of the
      inefficiencies resulting from startup issues within this product line have
      been resolved, management believes certain of these start up
      inefficiencies will continue into fiscal year 1998.
 
    - EUROPE Year over year operating income in European operations decreased
      $5.3 million. This decrease is a combination of soft market conditions
      plus the inclusion of several high margin jobs in the previous year
      results.
 
    - ABSORPTION CHILLER MARKET The cessation of natural gas rebates and
      incentive programs by utilities unfavorably impacted the absorption
      chiller market in fiscal year 1997. In addition to volume shrinkage during
      fiscal year 1997, the Company encountered certain warranty problems on
      absorption chiller units. As a result of the significant market downsize,
      the Company recognized a charge for obsolete and excess inventory.
      Absorption chiller sales decreased more than 60% during fiscal year 1997
      as compared to 1996. These absorption chiller conditions reduced fiscal
      year 1997 operating income by $3.5 million from the previous year.
 
FILTRATION PRODUCTS GROUP
 
    NET SALES.  Net sales were $352.8 million in fiscal 1997, an increase of
$11.1 million, or 3.3%, from $341.7 million for the fiscal year ended June 30,
1996. Environmental products sales increased 15.4% due to volume increases in
Europe, Asia and Latin America plus the acquisition of a German engineering
company. These increases were partially offset by decreased replacement air
filter sales in 1997 as compared to 1996.
 
    International sales for fiscal year 1997 increased 10.6% from fiscal year
1996 resulting from continued growth in emerging markets in Asia and Latin
America plus an 11% increase in European environmental products sales in fiscal
year 1997. These sales increases were diluted by the impact of unfavorable
currency translation of approximately $7 million along with a decline in
European replacement air filter product sales due to soft market conditions.
 
    Sales from U.S. operations for the fiscal year ended June 30, 1997 decreased
5.0% from fiscal year 1996. The decrease in domestic sales was primarily
attributable to complexities and difficulties in execution of new initiatives
such as the implementation of new software systems, field sales office
consolidation and establishment of a centralized call center and manufacturing
integration; all of which affected product delivery schedules. Management
believes difficulties in executing these initiatives have been largely contained
or overcome.
 
    OPERATING INCOME EXCLUDING AMORTIZATION.  Operating income excluding
amortization was $28.9 million in fiscal year 1997, a decrease of $6.0 million,
or 17.2%, from $34.9 million for the fiscal year 1996. Operating income
excluding amortization as a percent of sales decreased from 10.2% to 8.2%. Gross
margins decreased to 31.0% from 33.3% as a percentage of sales for the fiscal
years ended June 30, 1997 and June 30, 1996, respectively. Fiscal year 1997
gross margin rates declined due primarily to high manufacturing cost variances
resulting from difficulties in the execution of certain strategic initiatives.
Additionally, certain product lines experienced margin rate deterioration due to
competitive pricing pressures and initiation of certain pricing strategies aimed
at increasing market share, principally in Europe. SG&A excluding amortization
as a percentage of fiscal year 1997 sales remained constant at the prior year
level. Expense reductions gained from cost containment measures and decreased
field sales expenses resulting from the field sales office consolidation were
more than offset by volume related expense increases plus incurrence of
strategic expenses such as staffing and developing an Asian office, software
systems consulting and increased expenditures in research and development
engineering to help meet the growing demand for new products.
 
NON-OPERATING EXPENSES
 
    Interest expense was $26.0 million for the fiscal year ended June 30, 1997
versus $25.0 million for the fiscal year ended June 30, 1996. The interest
expense increase was primarily attributable a higher effective borrowing rate
and increased borrowings as a result of the J&E Hall Acquisition in mid year
fiscal year 1996. Amortization expense was $11.6 million for the fiscal year
ended June 30, 1997 versus $13.5 million for the fiscal year ended June 30, 1996
due to the Company changing its estimated useful life of goodwill
 
                                       21
<PAGE>
from 25 to 40 years effective April 1, 1996. Other expense of $.6 million for
the year ended June 30, 1997 and other income of $3.2 million for the year ended
June 30, 1996 consists primarily of foreign currency transaction losses and
gains and income from equity affiliates. The change year over year is primarily
due to currency gains not repeated and reduced income from equity affiliates
during the current year.
 
    Income tax expense was $6.9 million and the effective tax rate was 49.3% for
the fiscal year ended June 30, 1997 compared to income tax expense of $18.4
million and an effective tax rate of 52.7% for the fiscal year ended June 30,
1996. The effective income tax rate was substantially higher than the U.S.
federal statutory rate primarily due to nondeductible goodwill amortization and
foreign losses not benefited. The reduction in the effective rate was partially
attributable to the implementation of a foreign sales corporation, more
efficient utilization of foreign tax credits and the mix in earnings.
 
1996 COMPARED TO COMPARABLE PERIOD 1995
 
CONSOLIDATED
 
    NET SALES.  Consolidated net sales, including the acquisition of J&E Hall,
were $901.4 million for the fiscal year ended June 30, 1996 an increase of $99.6
million, or 12.4%, from $801.8 million in the Comparable Period ended July 1,
1995. International sales increased $57.6 million and domestic sales increased
by $42.0 million.
 
    OPERATING INCOME.  Consolidated operating income was $56.7 million or 6.3%
of net sales for the fiscal year ended June 30, 1996 an increase of $14.8
million from $41.9 million or 5.2% of net sales for the Comparable Period ended
July 1, 1995.
 
    During the Comparable Period ended July 1, 1995, the closing date for
certain foreign subsidiaries was changed to reflect the Company's current
period. Prior to this, certain foreign subsidiaries reported on fiscal periods
which ended one month prior (the "Lag Month" ) to the Company's period end. As a
result, the financial statements, for the Comparable Period ended July 1, 1995,
include the Lag Month, or a 13th month, of these foreign subsidiaries.
Management will discuss the financial results excluding the Lag Month in order
to improve comparability. The following table summarizes the Company's net
sales, and operating income, excluding amortization, adjusted for the Lag Month,
by business segment.

COMMERCIAL AIR CONDITIONING AND REFRIGERATION GROUP
 
    NET SALES.  Net sales, including seven months of J&E Hall sales, were $566.8
million in fiscal year 1996, an increase of $108.8 million, or 23.8%, from
$458.0 million for the Comparable Period ended July 1, 1995. North American
sales, for the 1996 fiscal year, increased 9.6% over Comparable Period ended
July 1, 1995. This increase was primarily the result of increased Chiller
Product sales due to the acceptance of new products utilizing the single screw
technology plus increased exports to Asia and Latin America. The growth in
exports is the result of strategic alliances and marketing strategies aimed at
gaining market share in these areas. International sales, for the fiscal year
ended June 30, 1996 increased 68.3% over the
 
                                       22
<PAGE>
Comparable Period ended July 1, 1995; substantially due to the acquisition of
J&E Hall which provided additional sales of $40.8 million and sales increases in
Italy, the United Kingdom, and France. These increases were the result of
several factors including the completion of a large one-time contract in the
United Kingdom, the introduction of a new product in Italy and an increase in
export sales from operations in France.
 
    OPERATING INCOME EXCLUDING AMORTIZATION.  Operating income excluding
amortization was $37.2 million in fiscal year 1996, an increase of $14.7 million
from $22.5 million for the Comparable Period ended July 1, 1995. Operating
income excluding amortization as a percent of sales increased from 4.9% to 6.6%.
Gross margins decreased to 25.2% from 26.2% as a percentage of sales for the
fiscal year and Comparable Period ended June 30, 1996 and July 1, 1995,
respectively. The decline in margin is primarily due to U.S. operations which
declined as a result of competitive price pressures and production start-up cost
for a new product. The decline in domestic gross margin was slightly offset by
increased margin rates for international operations. Selling, General &
Administrative expense ("SG&A") excluding amortization as a percentage of sales
decreased 2.8 percentage points in fiscal year 1996 from the Comparable Period
ended July 1, 1995. This decrease was due to cost containment actions, the
realization of cost saving strategies implemented by the Company during the
prior year and increased volume levels.
 
FILTRATION PRODUCTS GROUP
 
    NET SALES.  Net sales were $341.7 million in fiscal 1996, an increase of
$15.3 million, or 4.7%, from $326.4 million for the Comparable Period ended July
1, 1995. Sales from U.S. operations, for the fiscal year ended June 30, 1996
increased 7.0% over the Comparable Period ended July 1, 1995. This increase was
primarily the result of increased market share for Machinery Filtration &
Acoustic Systems ("MFAS") and overall market growth in Air Filtration Product
markets for commercial and retail use. International sales, for the 1996 fiscal
year, increased 2.1% from the 1995 Comparable Period. International sales gains
from market share increases for MFAS were partially offset by declines in Air
Filtration and Environmental products sales in Europe and Mexico. The effect of
foreign currency exchange rates, deteriorated net sales by approximately $1.2
million, almost exclusively from the devaluation of the Mexican Peso.
 
    OPERATING INCOME EXCLUDING AMORTIZATION.  Operating income excluding
amortization was $34.9 million in fiscal year 1996, an increase of $2.3 million
from $32.6 million for the Comparable Period ended July 1, 1995. Operating
income excluding amortization as a percent of sales increased from 10.0% to
10.2%. Gross margins increased to 33.3% from 33.1% as a percentage of sales for
the fiscal year and Comparable Period ended June 30, 1996 and July 1, 1995,
respectively. Margin rates for domestic operations decreased 1.0 percentage
point due to increased competition across most product lines which was partially
offset by production efficiencies. International margin rates increased
approximately 1.5 percentage point primarily the result of increased MFAS sales
across Europe. SG&A excluding amortization remained relatively flat as a
percentage of sales for the fiscal year 1996 as compared to the Comparable
Period ended July 1, 1995.
 
NON-OPERATING EXPENSES
 
    Interest expense was $25.0 million for the fiscal year ended June 30, 1996
versus $22.8 million for the Comparable Period ended July 1, 1995. The increase
was primarily attributable to an increase in borrowing to fund the acquisition
of J&E Hall. Amortization expense was $13.5 million for the fiscal year ended
June 30,1996 versus $13.8 million for the Comparable Period ended July 1, 1995.
Effective April 1, 1996 the Company changed its estimated useful life of
goodwill from 25 to 40 years. The effect of this change in estimate on
amortization expense recognized for the 1996 fiscal year was a decrease of
approximately $.8 million. Other income of $3.2 million for the year ended June
30, 1996 and $1.2 million for the Comparable Period ended July 1, 1995 consists
primarily of foreign currency transaction gains, gains from an insurance
settlement and sale of a product line, and income from equity affiliates.
 
    Income tax expense was $18.4 million and the effective tax rate was 52.7%
for the fiscal year ended June 30, 1996 compared to income tax expense of $12.9
million and an effective tax rate of 63.5% for the Comparable Period ended July
1, 1995. The effective income tax rate was substantially higher than the U.S.
federal statutory rate primarily due to nondeductible goodwill amortization and
foreign tax credits not utilized. The reduction in the effective rate was
primarily attributable to diminished impact of nondeductible goodwill
amortization.
 
                                       23
<PAGE>
    LIQUIDITY AND CAPITAL RESOURCES
 
    The Company's liquidity needs are provided by cash generated from operating
activities and supplemented when necessary by short-term credit facilities. For
the year ended June 30, 1997, net cash provided by operating activities was
$26.2 million as compared to a generation of $28.0 million for the year ended
June 30, 1996. This decrease is due to lower earnings, offset slightly by less
cash used in operating assets and liabilities. For the fiscal year ended June
30, 1997 net cash used by investing activities of $21.3 million consisted of
capital expenditures of $15.9 million and acquisition of businesses of $5.3
million while net cash used in financing activities was $15.1 million, comprised
of $10.3 million in scheduled payments on long-term debt, $2.0 million in term
debt borrowing and $6.8 million in net repayments under short-term borrowing
arrangements. During the year ended June 30, 1997, the Company reduced its cash
balances, primarily held at foreign subsidiaries, from $20.8 million to $10.8
million and applied such cash against its short-term borrowings.
 
    The Company has secured certain letter of credit facilities totaling $25
million that are supported by letters of credit from OYL, the Company's parent,
which were fully utilized at June 30, 1997 and June 30, 1996. The commitments
made under these facilities expire in March 1998, but may be extended annually
for successive one year periods with the consent of OYL and the banks providing
the facilities.
 
    J&E Hall Limited, a wholly-owned, U.K. based subsidiary of the Company, has
a short-term credit facility supported by a letter of credit from OYL.
Borrowings under this facility totaled $15.6 million at June 30, 1997 and $23.1
million at June 30, 1996. In addition, the Company's wholly-owned subsidiary in
Canada has a short-term credit facility supported by a letter of credit from
OYL. Borrowings under this facility were $5.8 million at June 30, 1997. Each of
these arrangements expire in September 1998, but may be extended annually for
successive one year periods with the consent of OYL and the banks providing the
facilities.
 
    During fiscal year 1997, the Company has entered into an agreement to sell
the net assets of the industrial fan business. The sale transaction is expected
to close by no later than October 31, 1997 with expected gross sales proceeds of
approximately $18.0 million which will be used to reduce debt. The sale of the
fan business will not have a material effect on the Company's future financial
results. On an on-going basis the Company strives to evaluate its various
businesses and product lines with the objective to enhance shareholder value.
Consistent with this strategy the Company intends to pursue global business
opportunities that are synergistic with the Company's core business or exit low
value added or non-synergistic operations.
 
    Planned capital expenditures are approximately $25 million for the year
ending June 30, 1998 and approximately $19 million for the year ending June 30,
1999.
 
    The Company is in the process of replacing many of its legacy systems and
upgrading its systems to improve overall business performance and to accommodate
business for the year 2000. However, given the inherent risks for a project of
this magnitude and the resources required, actual results could differ
materially from those anticipated by the Company. The estimated total cost of
the project is approximately $16 million. The Company expects its year 2000 date
conversion project to be completed on a timely basis. However, there can be no
assurance that the systems of other companies on which the Company may rely also
will be timely converted or that such failure to convert by another company
would not have an adverse effect on the Company's systems. To date, the Company
has spent $1.9 million on the year 2000 project.
 
    The ongoing costs of compliance with existing environmental laws and
regulations and the estimated costs to clean up and monitor existing
contaminated sites is not expected to have a material adverse effect on the
Company's capital expenditures or financial position. See "Legal Proceedings"
and Note 12 to the Consolidated Financial Statements.
 
    The Predecessor Company's U.S. federal income tax returns for the taxable
years ending in 1987, 1988, 1989 and 1990 have been examined by the Internal
Revenue Service. Adjustments to the taxable income for each of these years have
been proposed. Portions of the resulting tax liabilities would be imposed
directly on the Company or its subsidiaries, and the Company is obligated under
the stock purchase agreement between OYL and the former owners of the
Predecessor Company to make payments to the former owners of the Predecessor
Company to compensate them for the remainder of the tax liabilities which would
be imposed on them under Subchapter S of the Internal Revenue Code. That
agreement also entitles the Company to payments from the former shareholders of
the Predecessor
 
                                       24
<PAGE>
Company of certain tax refunds or benefits which the former owners may realize.
The Internal Revenue Service has also opened an examination of the Predecessor
Company's tax returns for the years ending in 1991, 1992, 1993 and 1994. Other
than issues originating in earlier years which would also affect these years,
there have been no issues raised in this examination.
 
    As more fully described in the Notes to the Consolidated Financial
Statements, the stock purchase agreement between OYL and the former owners of
the Predecessor Company contains certain indemnifications related to specified
contingencies related to environmental, income tax and litigation matters,
including those described above. See "Certain Relationships and Related
Transactions." Indemnified losses (net of recoveries) exceeding $5.8 million up
to a maximum of $18.0 million are the obligation of the former owners. Amounts
expended in excess of $5.8 will first offset the $11.5 million promissory note
owed to the former owners while additional amounts expended will be reimbursed
by the former owners up to $6.5 million.
 
    The Company has manufacturing facilities and sells products in various
countries around the world. As a result, the Company is exposed to movements in
exchange rates of various currencies against the U.S. dollar. Management's
response to currency movements vary (e.g. changes in pricing actions, changes in
cost structures and changes in hedging strategy). Currently, the Company enters
into short-term forward exchange contracts to hedge its exposure to currency
fluctuations affecting certain foreign currency denominated trade payables and
certain intercompany debt of its foreign subsidiaries. The Company will continue
to report, from time to time, fluctuations in both earnings and equity due to
foreign exchange movements since it is not cost-effective to establish a hedging
strategy that eliminates all risks.
 
    In August 1996, the Company canceled the Securitization Program (see note 7)
and increased the Revolving Credit portion of the Bank Agreement from $35
million to $100 million. (the "August 1996 Amendment") Trade accounts receivable
previously encumbered under the Securitization Program were consequently
re-pledged under the Bank Agreement via the August 1996 Amendment. The overall
net impact on the Company's average interest rate did not change significantly.
As of June 30, 1997, remaining borrowing availability under the $100 million
Revolving Credit portion of the Bank Agreement was $63.4 million. In August of
1997, the Company amended its Bank Agreement and reduced the Revolver commitment
portion from $100 million to $80 million.
 
    Management believes, based upon current levels of operations and forecasted
earnings, that cash flow from operations, together with borrowings under the
Amended Credit Facility (as amended in August 1997) and other short-term credit
facilities, will be adequate to make payments of principal and interest on debt,
to permit anticipated capital expenditures and to fund working capital
requirements and other cash needs. Nevertheless, the Company will remain
leveraged to a significant extent and its debt service obligations will continue
to be substantial. If the Company's sources of funds were to fail to satisfy the
Company's requirements, the Company may need to refinance its existing debt or
obtain additional financing. There is no assurance that any such new financing
alternatives would be available, and, in any case, such new financing (if
available) would be expected to be more costly and burdensome than the debt
agreements currently in place.
 
    SEASONALITY
 
    The demand for certain replacement filter products, particularly residential
filters, is seasonal in nature. Normally, sales of residential filters are
relatively low in the winter and early spring with an increase in sales during
the late spring, summer and fall months. Replacement air filter sales in the
commercial and industrial markets are also higher during the spring and summer
months, although these sales are driven primarily by maintenance cycles. Sales
of some air filtration equipment are seasonal to the extent that construction
activity increases during the warmer months.
 
    Sales of commercial air conditioning equipment are generally not seasonal.
However, the Company's air conditioning service business is seasonal in nature
due to off-season maintenance cycles and service needs during the summer months.
Demand for unitary air conditioning equipment in the small unit commercial new
construction markets varies according to the season, with increased demand
generally from March to October. Demand in the small unit commercial replacement
markets is impacted by seasonal temperature fluctuations. Sales of unit
ventilators for educational facilities tend to increase in the second and third
calendar quarters of any given year in part due to the start of a new school
year as well as the availability of bond or other funds budgeted for capital
expenditures.

    We have audited the accompanying consolidated balance sheets of AAF-McQuay
Inc. and subsidiaries as of June 30, 1997 and June 30, 1996 and the related
consolidated statements of operations, cash flows and stockholder's equity for
the years ended June 30, 1997 and June 30, 1996, the period from January 1, 1995
to July 1, 1995 and the period from May 2, 1994 to December 31, 1994. 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 consolidated financial position of AAF-McQuay Inc.
and subsidiaries at June 30, 1997 and June 30, 1996 and the consolidated results
of their operations and their cash flows for the years ended June 30, 1997 and
June 30, 1996, the period from January 1, 1995 to July 1, 1995 and the period
from May 2, 1994 to December 31, 1994 in conformity with generally accepted

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION
 
    The accompanying financial statements include the accounts of AAF-McQuay
Inc. (the Company), a wholly-owned subsidiary of AAF-McQuay Group, Inc., and its
subsidiaries. AAF-McQuay Group, Inc. is a wholly-owned subsidiary of O.Y.L.
Industries Berhad ("OYL"). In December 1995, AAF-McQuay Group, Inc. contributed
all of its ownership interest in AAF-McQuay Holdings, Inc. to the Company. AAF-
McQuay Holdings, Inc. holds minority investments in certain companies. Since
this transaction represents a combination of entities under common control, it
has been treated in a manner similar to a pooling of interests. Accordingly, the
accompanying financial statements reflect the consolidated financial results of
these entities from the beginning of the periods presented.
 
    On May 2, 1994 OYL and affiliates purchased all of the outstanding stock of
SnyderGeneral Corporation and SnyderGeneral Holding Company, collectively the
"Predecessor Company". Subsequent to this acquisition, the names of these
entities were changed to AAF-McQuay Inc. and AAF-McQuay Holdings, Inc.,
respectively. The aggregate purchase price was approximately $108 million and
consisted of $88.5 million in cash to the former owners of the Predecessor
Company, payment of seller transaction costs of $5 million, other related
transaction costs of approximately $3.0 million, and an $11.5 million promissory
note (see Note 7) issued to the former owners of the Predecessor Company.
 
    The acquisition by OYL was accounted for under the purchase method of
accounting and the accompanying financial statements reflect OYL's cost basis in
the Predecessor Company. Under this method, OYL's purchase price was allocated
to assets acquired and liabilities assumed based on their fair value at the date
of acquisition. A summary of the fair value of assets acquired and liabilities
assumed as of May 2, 1994 are as follows (dollars in thousands).

</TABLE>
 
    The Predecessor Company had operated with four business groups with several
functions administered on a centralized basis. In order to more clearly focus on
the need to increase the Company's global presence and to leverage the extensive
U.S. manufacturing and technology base, and in conjunction with the acquisition,
new management of the Company took actions to reorganize the Company to a global
product segment format. Further, to elevate accountability within the operating
business segments, administrative functions formerly centralized were
restructured and relocated to certain division locations. Also steps were taken
by new management of the Company to reduce excess capacity that existed at the
acquisition date. As a result of these restructuring actions, the Company
recognized an $17.2 million liability at the acquisition date consisting
primarily of employee termination costs of $12.8 million and employee relocation
costs of $2.7 million. As of June 30, 1996 all amounts had been paid and charged
against the related liability.
 
    The Company is a worldwide manufacturer and marketer of commercial air
conditioning and refrigeration and air filtration products and systems primarily
for commercial, institutional and industrial

customers. In December 1995, the Company entered the industrial refrigeration
business through the acquisition of J&E Hall, a United Kingdom's integrated
provider of industrial refrigeration and freezing equipment. The Company
maintains production facilities in nine countries and its products are sold in
over 80 countries.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    BASIS OF PRESENTATION
 
    The consolidated financial statements include the accounts of the Company
and all of its subsidiaries. All intercompany transactions and balances have
been eliminated. The accompanying financial statements reflect the financial
results of the Company for the fiscal years ended June 30, 1997 and June 30,
1996 and the periods from January 1, 1995 to July 1, 1995 and from May 2, 1994
to December 31, 1994. In 1995, the Company changed its fiscal year end from the
Saturday closest to December 31 to the Saturday closest to June 30 to coincide
with OYL's fiscal year. For clarity of presentation in the consolidated
financial statements, all full fiscal years are shown to begin on January 1 and
end on December 31, or to begin on July 1 and end on June 30. For the periods
presented on a basis other than a full fiscal year, actual period end dates are
used.
 
    Through December 31, 1994 certain foreign subsidiaries reported on fiscal
periods which ended one month prior to the Company's or Predecessor Company's
period-end. During the six month period ending July 1, 1995 the closing date for
the foreign subsidiaries was changed to reflect the Company's current closing
period. As a result, the July 1, 1995 financial statements include the financial
results of these foreign subsidiaries from December 1, 1994 through July 1,
1995. The impact on sales and income from operations for the period ended July
1, 1995 was increases in sales and income from operations of approximately $19.1
million and $0.7 million, respectively.
 
    The preparation of financial statements in accordance with Generally
Accepted Accounting Principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
    CASH AND CASH EQUIVALENTS
 
    The Company invests cash in excess of operating requirements in short-term
time deposits, money market instruments, or commercial paper. These investments
have original maturities of less than three months and are considered cash
equivalents for financial reporting purposes.
 
    INVENTORIES
 
    Inventories are valued at the lower of cost or market at June 30, 1997 and
June 30, 1996. Cost is determined by the last-in, first-out (LIFO) method for
U.S. inventories, (62% and 63%, respectively), and the first-in, first-out
(FIFO) method for the Company's foreign subsidiaries (38% and 37%,
respectively).
 
    PROPERTY, PLANT AND EQUIPMENT
 
    Property, plant and equipment are depreciated using the straight-line method
over their estimated useful lives as follows:
 
<TABLE>
<S>                                                            <C>

Buildings....................................................          years
Machinery and Equipment......................................  3 to 12 years
</TABLE>
 
    Maintenance and repairs are charged to operations when incurred, while
expenditures which have the effect of extending the useful life of an asset are
capitalized.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    INTANGIBLE ASSETS
 
    The excess of cost over fair values of net assets acquired are being
amortized on a straight-line basis over forty years. Other identifiable
intangibles acquired include trademarks and tradenames; technical drawings and
technology; and assembled work force, which are being amortized on a
straight-line basis over forty, fifteen and ten years, respectively. Effective
April 1, 1996 the Company changed its estimate for the useful life of goodwill,
tradenames and trademarks, relating to the OYL Acquisition, from 25 to 40 years
to better reflect the estimated periods over which economic benefits will be
realized.
 
    On a periodic basis, the Company evaluates the carrying value of its
intangible assets to determine if the facts and circumstances suggest that
intangible assets may be impaired. If this review indicates that intangible
assets may not be recoverable, as determined based on the undiscounted cash flow
of the entity acquired over the remaining amortization period, the Company's
carrying value of intangible assets is reduced by the estimated shortfall of
cash flows.
 
    DERIVATIVE FINANCIAL INSTRUMENTS
 
    Derivative financial instruments are used by the Company principally in the
management of its interest rate and foreign currency exposures. The Company does
not enter into speculative derivative transactions.
 
    The differential between interest rate cap premiums due and amounts
receivable under interest rate cap agreements are recognized as yield
adjustments to interest expense over the term of the related debt.
 
    Gains and losses on foreign exchange forward contracts are recognized in
income and offset the foreign exchange gains and losses on the underlying
foreign currency transactions.
 
    FOREIGN CURRENCIES
 
    Assets and liabilities of the Company's subsidiaries outside the U.S. are
translated into U.S. dollars at the exchange rates in effect at the end of the
period. Revenue and expense accounts are translated at a weighted average of
exchange rates in effect during the period. Translation adjustments that arise
from translating a foreign subsidiary's financial statements from local currency
(the functional currency) to U.S. dollars are reflected as a separate component
of stockholder's equity.
 
    Transaction gains and losses that arise from exchange rate changes on
transactions denominated in a currency other than the local currency are
included currently in the results of operations. The Company recognized net
foreign currency transaction (gains) losses of $425,000, ($1,444,000),
($948,000), and $617,000 for the fiscal years and periods ended June 30, 1997,
June 30, 1996, July 1, 1995, and December 31, 1994, respectively.
 
    REVENUE RECOGNITION
 
    Revenues and costs are generally recognized as products are shipped or
services are rendered. Revenues and costs associated with long-term contracts
are recognized on the percentage-of-completion method. Provisions are recorded
for losses on contracts whenever it is estimated that costs will exceed contract
value. Unbilled revenue recognized on long-term contracts is included in
accounts receivable in the accompanying Consolidated Balance Sheets.
 
    PRODUCT WARRANTIES
 
    Product warranties are provided as charges to current expense for estimated
normal warranty costs and, if applicable, for specific performance issues known
to exist on products sold. The expenses estimated to be incurred are provided at
the time of sale, based primarily upon estimates derived from experience.
Warranty costs on some purchased parts and components are partially reimbursed
to the Company by

supplying vendors. Estimated obligations beyond one year are classified as other
long-term liabilities. Revenue from the sale of extended warranty and related
service contracts is deferred and amortized over the respective contract life on
a straight-line basis.
 
    RESEARCH AND DEVELOPMENT COSTS
 
    Research and development costs were approximately $10.6 million, $8.2
million, $4.3 million, and $5.5 million for the fiscal years and periods ended
June 30, 1997, June 30, 1996, July 1, 1995, and December 31, 1994, respectively,
and are included in selling, general and administrative expenses in the
accompanying Consolidated Statements of Operations.
 
    INCOME TAXES
 
    The Company uses the liability method for financial accounting and reporting
of income taxes. Under the liability method, deferred tax assets and liabilities
are determined based on the difference between financial statement carrying
amounts and the tax bases of assets and liabilities. These differences are
measured at the enacted tax rates that will be in effect when these differences
reverse.

</TABLE>
 
    The Company manufactures and sells heating, ventilating, air conditioning,
refrigeration and air filtration products to companies in various industries
with the most significant sales concentration being in the construction
industry. The Company performs periodic evaluations of its customers' financial
condition and generally does not require collateral. For domestic equipment
sales, it is the Company's practice to attach liens in the event of non-payment,
when such recourse is available. Trade receivables generally are due within
30-90 days.

7. DEBT
 
    In July 1994, the Company entered into a Revolving Credit, Letter of Credit,
and Term Loan Agreement (Bank Agreement). In February 1996, an amendment to the
Bank Agreement was executed in which the lenders consented to the issuance of
the $125 million Senior Unsecured Notes and an $80 million Receivables
Securitization Program. The February 1996 amendment significantly restated Bank
Agreement commitment amounts, repayment terms, interest rates, and security
provisions. In August 1996, the Company terminated the Receivables
Securitization program and increased the Revolver commitment portion of the Bank
Agreement from $35 million to $100 million. In August of 1997, the Company
amended its Bank Agreement and reduced the Revolver commitment portion from $100
million to $80 million. The Revolving Credit portion of the Bank Agreement
("Revolver"), as amended in August 1997, expires in February, 2001 and provides
for maximum aggregate short-term borrowings of $80 million and up to $75 million
for letters of credit. However, the combined amount of short-term borrowings
plus letters of credit cannot exceed $80 million. Use of the Revolver is subject
to the Company's availability (as defined in the Bank Agreement) and is based on
the Company's level of domestic receivables and inventories. At June 30, 1997,
under the August 1996 amendment, borrowings of $33.0 million were outstanding
under this facility, $1.7 million in letters of credit were issued and
outstanding and the Company had approximately $63.4 million in additional
borrowing availability. The Company is required to pay a commitment fee of 3/8%
on the unused portion of the Revolver.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
7. DEBT (CONTINUED)
    Interest on Revolver advances is generally payable quarterly based, at the
Company's option, on (1) the higher of the bank prime rate or a rate based upon
the Federal Funds Rate plus a specified premium, or (2) the average rate at
which Eurodollar deposits are offered to prime banks in the London interbank
market (LIBOR) plus a specified premium. The interest rate premiums are
determined by an interest rate matrix which is based on certain quarterly
financial ratios as described in the Bank Agreement. As of June 30, 1997 the
Company's interest rate premiums were LIBOR + 1.50% or prime + 0.50% based on
the applicable financial ratios. The interest rate premiums are subject to a
0.375% increase or may decrease by as much as 0.50%, depending on the applicable
quarterly financial ratios. At June 30, 1997 the Company's borrowing rate under
the Bank Agreement, was approximately 7.20%. The average effective interest rate
under the Bank Agreement for the fiscal year ended June 30, 1997 was
approximately 7.18%.
 
    In February 1996, the Company entered into a five-year agreement to sell, on
a revolving basis, an undivided percentage ownership interest in a designated
pool of trade accounts receivable ("Securitization Program"). The Securitization
Program provided for up to $80 million in short term borrowings. Availability
was based on the amount of U.S. dollar trade receivables determined to be
eligible for the program. At June 30, 1996 the Company had $36.0 million of
outstanding borrowings under the Securitization Program arrangement and
approximately $20 million in additional borrowing availability. Both the
accounts receivable and related short term debt were included in the Company's
June 30, 1996 consolidated balance sheet. Related financing costs have been
included in interest expense. The Securitization program was terminated in
August 1996 when the Company increased its Revolving Credit Commitment portion
of its Bank Agreement.
 
    At June 30, 1997 certain of the Company's foreign subsidiaries had available
lines of credit with foreign banks of approximately $50 million which may be
drawn as needed at an average interest rate of approximately 7%. Outstanding
borrowings against international lines of credit amounted to approximately $25.2
million and $29.5 million at June 30, 1997 and June 30, 1996, respectively. In
addition, certain of the Company's foreign subsidiaries have non-borrowing bank
facilities (letters of credit, guarantees, performance bonds, etc.) totaling
$25.0 million as of June 30, 1997 and June 30, 1996 of which approximately $19.2
million was used at June 30, 1997 and $18.0 million was used at June 30, 1996.
 
    The Company's foreign subsidiaries have agreements in place whereby they can
sell trade receivables on a revolving basis, with limited recourse. The
subsidiaries pay fees equal to approximately an annual interest rate of 9% on
such receivables outstanding. The fees are included in interest expense.
Provisions for losses on receivables sold which become uncollectible are
included in the Company's allowance for doubtful receivables. Receivables sold
which remained uncollected were $0.7 million and $0.1 million at June 30, 1997
and June 30, 1996, respectively.
 
    The Company also has available letter of credit facilities totaling $25
million which are supported by a letter of credit from OYL and were fully
utilized at June 30, 1997 and June 30, 1996. The commitments made under these
facilities expire in March of 1998, but may be extended annually for successive
one year periods with the consent of OYL and the banks providing the facilities.
 
    The weighted average effective interest rate on short-term borrowings was
7.1% at June 30, 1997 and 6.1% at June 30, 1996.

</TABLE>
 
    The term loan portion of the Bank Agreement consists of Senior Term Loans
that are a direct obligation of the Company. These term loans are secured by
substantially all the domestic assets of the Company and its domestic
subsidiaries and a portion of the capital stock of certain foreign subsidiaries.
The Senior Term Loans are payable in quarterly installments of varying amounts
through March 2001. Interest is generally payable quarterly based on the same
interest rate structure as the Revolver.
 
    The Bank Agreement contains covenants that, among other things, impose
limitations on incurrence of indebtedness, capital expenditures, transactions
with affiliates, mergers and the disposition of assets, investments by the
Company, and transactions involving the capital of the Company, including
payment of any dividends. In addition, the Bank Agreement contains financial
covenants (as amended in August of 1997 retroactive to June 30, 1997) relating
to net worth, leverage ratio, interest coverage, and fixed charge coverage. At
June 30, 1997 and June 30, 1996 the Company was in compliance with the amended
financial covenants.
 
    The Bank Agreement also contains provisions requiring accelerated payments.
The generation of cash resulting from, among other things, the sale of any
material asset, collection of any special receipt (as defined) or any excess
cash flow (as defined) require certain accelerated payments. No accelerated
payments were required during the fiscal year and period ended June 30, 1997 or
June 30, 1996.
 
    The $11.5 million, 6% Promissory Note was issued in connection with the May
2, 1994 acquisition and is payable to a bank, as paying agent for the benefit of
certain former stockholders of the Predecessor Company. The Promissory Note is
subject to offsets and increases (but not in excess of the original current
amount) associated with indemnifications and any proceeds of recovery (as
defined).
 
    In February 1996, the Company issued the 8.875% Senior Unsecured Notes
("Senior Notes") with the proceeds being used to reduce indebtedness under the
Bank Agreement. The Senior Notes were issued under an indenture agreement which,
among other things, contains restrictive covenants relating to dividend
distributions, additional debt, sale of assets, transactions with affiliates,
guarantees and investments by the Company and its subsidiaries. The Senior Notes
are not redeemable prior to maturity (February 15, 2003) and are not subject to
any sinking fund requirement.
 
    Included in other issues of long term debt are various term loans incurred
by certain foreign subsidiaries, as well as obligations under Industrial Revenue
Bonds and mortgage notes. The foreign term loans are secured by certain assets
of the issuing foreign subsidiary and contain various repayment terms ranging
from 5 to 15 years. The outstanding balance of these foreign term loans was
$11.5 million and $13.3 million at June 30, 1997 and June 30, 1996,
respectively.
 
    The Company paid cash interest of $24.8 million, $21.7 million $10.9
million, and $29.4 million for the fiscal years and periods ended June 30, 1997,
June 30, 1996, July 1, 1995, and December 31, 1994, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
7. DEBT (CONTINUED)
    Maturities of long-term debt during each of the next five fiscal years
subsequent to June 30, 1997 are as follows (dollars in millions): 1998, $12.1;
1999, $31.5; 2000, $24.8; 2001, $23.5; 2002, $1.0.
 
8. FINANCIAL INSTRUMENTS
 
    The Company operates internationally and borrows at floating interest rates,
giving rise to exposure to market risks from changes in foreign exchange rates
and interest rates. The Company utilizes derivatives to reduce those risks. The
notional amounts of derivatives noted below do not represent amounts exchanged
by the parties and, thus, are not a measure of the exposure of the Company
through its use of derivatives. The Company does not hold or issue derivative
financial instruments for trading purposes.
 
    INTEREST RATE RISK MANAGEMENT:  The Company may, at times, seek to limit the
impacts of rising interest rates on its variable rate debt through the use of
interest rate derivative instruments. The Company entered into a series of
three-year, interest rate cap agreements ("Caps") in 1994 to hedge 100% of its
variable interest rate Senior Term Loans against floating interest rates. The
notional amount ($174.6 million at July 1, 1995) of the Caps was scheduled to
reduce at the same rate and time as quarterly amortization payments are made on
the Senior Term Loans. Under the terms of the Caps, the Company received a cash
payment if the 90-day LIBOR interest rate was above a certain stated cap level
at various quarterly measurement dates. For the periods ended July 1, 1995 and
December 31, 1994 the Company recorded a net benefit of $1.2 million and
$121,000, respectively, under the Caps as a reduction to interest expense. In
December 1995, the interest rate cap agreements were terminated. The deferred
loss on the early termination of these agreements was not material. The Company
entered into a new amortizing interest rate swap agreement with an initial
notional amount of $100 million. Under this agreement the Company pays an
interest rate equal to LIBOR when LIBOR is greater than 4.75% or less than 6.6%;
otherwise, the Company pays an interest rate of 6.6%. This swap agreement was
terminated in June 1996. The gain on early termination of the swap agreement was
not material. There were no interest rate derivative transactions completed
during the fiscal year ended June 30, 1997.
 
    FOREIGN CURRENCY MANAGEMENT:  The Company enters into short-term foreign
exchange contracts to hedge its exposure to currency fluctuations affecting
certain foreign currency denominated trade payables and certain intercompany
debt of its foreign subsidiaries. The notional amount of foreign exchange
forward contracts outstanding at June 30, 1997 and June 30, 1996 was
approximately $32.2 million and $34.7 million, respectively. The U.S. dollar
equivalent notional amount of these foreign exchange forward contracts by
applicable foreign currency at June 30, 1997 and June 30, 1996 was as follows:
Canadian dollars, $4.2 million and $10.7 million; Singapore dollars $3.1 million
and $5.9 million; German marks $3.1 million and $0.0 million; Italian lira $4.3
million and $2.6 million; French francs $13.4 million and $15.2 million; and
various other currencies $4.1 million and $0.3 million.
 
    The Company is exposed to credit-related losses in the event of
non-performance by counterparties to derivative financial instruments. The
Company monitors the credit worthiness of the counterparties and presently does
not anticipate nonperformance by the counterparties. The credit exposure of
derivative financial instruments is represented by the fair value of contracts
with a positive fair value.
 
    FASB Statement No. 107, DISCLOSURES ABOUT FAIR VALUES OF FINANCIAL
INSTRUMENTS, defines the fair value of a financial instrument as the amount at
which the instrument could be exchanged in a current transaction between willing
parties. The carrying values reported in the balance sheets for cash and cash
equivalents, accounts receivable and short-term borrowings approximate their
respective values. The fair value of the Company's Senior Unsecured Notes is
estimated using a quoted market price. The carrying amount of all other
long-term debt approximates fair value. The carrying amount of the Company's
long-term debt at June 30, 1997 of $229.1 million approximates fair value. The
aggregate fair value of the Company's long-term debt at June 30, 1996 was $233.6
million compared to the carrying value of $237.4 million. The fair values of the
Company's foreign exchange forward contracts are based on current settlement
values and fees currently charged to enter into similar agreements, taking into
account the

remaining terms of the agreements and the counterparties' credit standing. At

9. INCOME TAXES
 
    Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets and liabilities at June 30, 1997 and June 30,
1996 are as follows (dollars in thousands):

10. EMPLOYEE BENEFIT PLANS
 
    The Company has defined benefit pension plans in effect for substantially
all of its domestic hourly employees and certain of its foreign employees.
Benefits are computed using formulas which are generally based on age and years
of service. Plan assets consist primarily of common stock, insurance contracts
and government obligations. The Company's method of funding pension costs is to
contribute amounts to the plans sufficient to meet minimum funding requirements,
plus such amounts as the Company may determine to be appropriate from time to
time.

    The weighted average discount rate used to measure the projected obligation
for the domestic plans was 8.00% and 7.75% as of June 30, 1997 and June 30,
1996, respectively. The computations above for domestic plans assumes an
expected long-term rate of return on assets of 9% for each period presented.
 
    The foreign plans included in the preceding tables used weighted average
discount rates ranging from 6.0% to 8.5% at June 30, 1997 and June 30, 1996. The
assumed rate of increase in future compensation levels ranged from 4.0% to 5.0%
at June 30, 1997 and June 30, 1996. The expected long-term rate of return on
assets was 7.0% to 9.0% for the fiscal year and period ended June 30, 1997, June
30, 1996, July 1, 1995, and December 31, 1994.

$1,071,000, $1,411,000, $646,000, and $1,190,000 under this plan during the
fiscal years and periods ended June 30, 1997, June 30, 1996, July 1, 1995, and
December 31, 1994, respectively.
 
    The Company also sponsors a 401(k) defined contribution plan that primarily
covers domestic salaried employees. Participants may contribute a percentage of
their compensation to the plan. Contributions are matched by the Company with
certain limitations. During the fiscal years and periods ended June 30, 1997,
June 30, 1996, July 1, 1995 and December 31, 1994 the Company expensed
$1,111,000, $1,094,000, $616,000, and $988,000, respectively, related to this
plan.
 
    The Company sponsors domestic defined benefit health care plans for certain
salaried and nonsalaried employees whereby certain health care and life
insurance benefits are provided on retirement. The benefits are provided only
for a frozen group of active employees and retirees. For these plans, medical
trend rates assume escalation of 9.5 percent decreasing gradually for four years
to the ultimate medical trend rate of 5.5 percent. The aggregate increase in the
accumulated postretirement benefit obligation and the service cost plus interest
for the domestic plan as of and for the fiscal year ended June 30, 1997 assuming
a one percentage point increase in the medical trend rate in each year is
$406,000 and $62,000, respectively. The weighted average discount rate used in
determining the June 30, 1997 and June 30, 1996 accumulated postretirement
benefit obligation was 7.75%. The domestic plans are unfunded.
 
    The Company also sponsors a foreign defined benefit health care plan for
certain salaried and nonsalaried employees whereby certain health care and life
insurance benefits are provided on retirement. For this plan, medical trend
rates assume escalation of 7 percent decreasing ratably to the ultimate medical
trend rate of 4.5 percent in the year 2010. The accumulated postretirement
benefit obligation and service cost plus interest would not increase
significantly assuming a one percent increase in the medical trend rate as of
and for the fiscal year ended June 30, 1997. The weighted average discount rate
used in determining the accumulated postretirement benefit obligation was 7.5%
at June 30, 1997 and June 30, 1996. The foreign plan is also unfunded.

    The Company has an employment agreement with an executive officer which
provides the executive the option to purchase a specified percentage of the
Company's common stock. Exercise of this option was contingent upon certain
performance measures being achieved and other conditions specified in the
agreement. The option provision of this contract has been superceded by the
adoption of a Company Stock Option Plan.
 
    In 1997, the Company adopted a Stock Option Plan which provides for the
grant of non-qualified stock options to certain members of management and key
employees to purchase the common stock of the Company's parent AAF-McQuay Group
Inc. The Company anticipates the granting of options under the stock option plan
during fiscal year 1998. The related impact to the Statement of Operations will
be based on an independent valuation of the Company at or near the grant date.

    Rental expense associated with third party operating leases was
approximately $11.4 million, $11.6 million, $5.6 million, and $7.8 million for
the fiscal years and periods ended June 30, 1997, June 30, 1996, July 1, 1995,
and December 31, 1994, respectively. It is expected that, in the normal course
of business, leases that expire will be renewed or replaced by leases on other
property and equipment.
 
    The Company has a contract whereby certain of its data processing operations
are managed by a third party. Monthly charges during the fiscal years and
periods ended June 30, 1997, June 30, 1996, July 1, 1995, and December 31, 1994
averaged approximately $945,800, $832,000, $684,000, and $758,000, respectively
under this contract. This contract extends through December 31, 2000 but
includes certain early termination options.

    INDEMNIFICATION AGREEMENT
 
    The purchase agreement between OYL and the former owners of the Predecessor
Company contains certain indemnifications relating to specified contingencies
that existed as of the acquisition date. Specifically, the former owners of the
Predecessor Company have an indemnification obligation for losses relating to
certain environmental, tax, and litigation matters.
 
    Under terms of the purchase agreement, the Company is responsible for the
first $5.8 million of indemnified losses. Indemnified losses (net of recoveries)
exceeding $5.8 million must be indemnified by the former owners of the
Predecessor Company up to a maximum of $18 million. If the ultimate amount
expended by the Company for contingencies subject to indemnification exceeds
$23.8 million, the excess will be borne by the Company. If the aggregate amount
expended is less than $23.8 million, the Company will first offset amounts
exceeding $5.8 million against the $11.5 million promissory note discussed in
Note 7. Indemnified losses in excess of $17.3 million would then be indemnified
by the former owners of the Predecessor Company up to $6.5 million. Claims for
indemnified losses can be made for up to five years after the acquisition date
of May 2, 1994. The Company believes that the ultimate liability for indemnified
losses will exceed $23.8 million and has recognized this noncurrent liability in
the accompanying Consolidated Balance Sheets. On January 29, 1997, the Company
instituted an action before the American Arbitration Association in Dallas,
Texas, to enforce the Company's rights to indemnification of all its claimed
losses; the arbitration is in the discovery and scheduling stages.
 
    ENVIRONMENTAL MATTERS
 
    The Company is subject to potential liability under the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980, as amended
(CERCLA), and other federal, state and local statutes and regulations governing
the discharge of pollutants into the environment and the handling and disposal
of hazardous substances and waste. These statutes and regulations, amongst other
things, impose potential liability on the Company for remediating contamination
arising from the Company's past and present operations and from former
operations of other entities at sites later acquired and now owned by the
Company. Many of the Company's facilities have operated for many years, and
substances which are or might be considered hazardous were generated, used, and
disposed of at some locations, both on and off-site. Therefore, it is possible
that environmental liabilities in addition to those described below may arise in
the future. The Company records liabilities if, in management's judgment,
environmental assessments or remedial efforts are probable and the costs can be
reasonably estimated. These accrued liabilities are not discounted. Such
estimates are adjusted if necessary based on the completion of a formal study or
the Company's commitment to a formal plan of action. The Company believes that
all environmental liabilities discussed below are subject to the indemnification
agreement with the former owners of the Predecessor Company described above.
 
    In 1988, a lawsuit was filed in federal court against the Predecessor
Company concerning the alleged release of trichloroethylene at a former Visalia,
California manufacturing facility (Visalia). In November 1990, the Predecessor
Company entered into a settlement agreement with all known potentially
responsible parties at Visalia whereby the Predecessor Company agreed to be
solely responsible for the costs of the remaining cleanup. As of June 30, 1997
the Company and Predecessor Company had incurred over $10.5 million for cleanup
costs and legal fees related to the Visalia site, and, although the exact amount
of the costs of this remediation is not ascertainable, the Company estimates
future probable costs to be approximately $6.8 million on a nondiscounted basis
through the year 2007 based upon cost projections provided by the Company's
environmental consultants.
 
    The Company had filed suit against several insurers seeking coverage with
respect to the Visalia site. The Company and Predecessor Company have already
settled with other insurers from which $11 million

has been recovered. No amounts have been recorded in the accompanying
Consolidated Balance Sheet relating to these potential recoveries.
 
    The Predecessor Company was named as a potentially responsible party arising
from accidental trichloroethane spills at a facility in Wilmington, North
Carolina. The Company estimates the probable expenses for future cleanup to be
approximately $5.3 million on a nondiscounted basis through the year 2007 based
upon cost projections provided by the Company's environmental consultants. The
Predecessor Company has already recovered from its primary insurance carrier the
limit of its policy related to this matter. The Company's excess insurance
carrier failed to respond to the Company's claim for coverage. As a result, the
Company filed suit against this carrier for recovery of the cleanup and
remediation costs at the Wilmington site. In November 1995, the Court granted
the carrier's Motion for Summary Judgment as to liability but denied the Motion
concerning the Company's bad faith and insurance code claims. The Company
appealed the order and the Appeals Court reversed the lower Court ruling. The
case has been set for trial in November 1997. The insurance carrier has filed a
new motion for Summary Judgment. No amounts have been recorded in the
accompanying Consolidated Balance Sheets relating to these potential recoveries.
 
    The Predecessor Company discovered contaminants in the soil and/or
groundwater at its manufacturing facilities in Faribault, Minnesota, Scottsboro,
Alabama, Staunton, Virginia and certain other manufacturing sites. The level of
contamination exceeds mandated levels and will require remediation. Based upon
estimates prepared by environmental consultants, at June 30, 1997 the Company
estimates that related probable remediation costs will be approximately $10.4
million. The Company is currently assessing its insurance coverage and potential
recovery of such costs from third parties. No amounts have been recorded in the
accompanying Consolidated Balance Sheets relating to these potential recoveries.
 
    INCOME TAX
 
    The Predecessor Company's U.S. federal income tax returns for the taxable
years ending in 1987, 1988, 1989 and 1990 have been examined by the Internal
Revenue Service. Adjustments to the taxable income for each of these years have
been proposed. Portions of the resulting tax liabilities would be imposed
directly on the Company or its subsidiaries, and the Company is obligated under
the purchase agreement to make payments to the former owners of the Predecessor
Company to compensate for the remainder of the tax liabilities which would be
imposed on them under Subchapter S of the Internal Revenue Code. That agreement
also entitles the Company to payments from the former shareholders of certain
tax refunds or benefits which the former owners may realize. Payments by the
Company under this agreement are indemnified losses under the purchase agreement
(as discussed above), and receipts by the Company from the former owners, as
well as certain other future tax benefits which the Company may realize on its
own tax returns must be subtracted from losses which are subject to
indemnification.
 
    In March 1995, the Internal Revenue Service opened an examination of the
Predecessor Company's tax returns for the years ending in 1991, 1992, 1993 and
1994. Other than issues originating in earlier years which would also affect
these years, there have been no material adjustments proposed during this
examination.
 
    LITIGATION
 
    The Company is involved in various lawsuits in the ordinary course of
business. These lawsuits primarily involve claims for damages arising out of the
use of the Company's products. The Company is also involved in litigation and
administrative proceedings involving employment matters and commercial disputes.
Some of these lawsuits include claims for punitive as well as compensatory
damages. The Company is insured for product liability claims for amounts in
excess of established deductibles and accrues for the estimated liability on a
case-by-case basis up to the limits of the deductibles. All other claims and
lawsuits are also handled on a case-by-case basis.

12. CONTINGENCIES (CONTINUED)
    The Company does not believe that the potential liability from the ultimate
outcome of environmental, income tax and litigation matters will have a material
adverse effect on it.
 
13. EXTRAORDINARY ITEM
 
    During fiscal year June 30, 1996 the Company completed the Refinancing. See
Note 7. As part of the Refinancing the Company used some of the proceeds from
the offering to repay long-term debt. As a result, the Company recorded an
extraordinary item of $1.6 million ($2.7 million net of $1.1 million tax
benefit) relating to an accelerated charge-off of unamortized debt issuance
cost.

course of business. Additionally during fiscal year 1997, the Company purchased
approximately $3.3 million of product from OYL and its subsidiary companies in
the ordinary course of business. The Company does not expect a change in this
policy and plans to continue to buy from and sell to OYL and Hong Leong related
entities in the future.
 
    The Company has entered into trademark license and royalty agreements with
O.Y.L. Manufacturing Company SDN BHD ("OMC") (the "OMC Agreement"), Shenzhen
O.Y.L. Electrical Co. Ltd. ("Shenzhen") (the "Shenzhen Agreement") and P.T.
O.Y.L. Sentra Manufacturing ("PT OYL"). Pursuant to such Agreements, the Company
has granted OMC, Shenzhen and PT OYL, respectively, nonexclusive,
nontransferable rights and licenses to use the trademark "McQuay" in connection
with the sale and marketing of certain products exclusively through Shenzhen's,
OMC's and PT OYL's respective international distribution networks. In exchange
for such grants, OMC, Shenzhen and PT OYL have each agreed to pay the Company
earned royalty payments ranging from 2% to 5% of the accumulated net sales of
such products. The Company has been paid or was owed $207,000 and $228,000
pursuant to the OMC Agreement, $81,000 and $39,000 pursuant to the Shenzhen
Agreement, and $27,000 and $3,000 pursuant to the PT OYL agreement for the years
ended June 30, 1997 and June 30, 1996, respectively. Each of OMC, Shenzhen, and
PT OYL are subsidiaries of OYL.
 
    In August 1995, the Company entered into an agreement with McQuay-Wuhan Air
Conditioning & Refrigeration Company Ltd. ("McQuay-Wuhan"), a joint venture of
Wuhan-New World Refrigeration Industrial Company Limited and McQuay Asia (Hong
Kong) Ltd., an OYL subsidiary, to license certain technology and trademarks for
use in the Peoples Republic of China in exchange for a royalty of 2%-3% of net
sales. Pursuant to such agreement, royalties from the first two years of the
contract will be accumulated and paid after the third year of the contract. Such
accumulated royalty payments will be made quarterly and the amount of such
payments will be dependent upon McQuay-Wuhan's financial condition.
 
    In January 1995, OYL loaned $10 million to the Company in exchange for which
the Company issued a promissory note in the principal amount of $10 million in
favor of OYL. In March 1995, the promissory note was transferred to the Company
as an additional capital contribution.
 
    In connection with the acquisition of J&E Hall, which is now a wholly-owned
subsidiary of the Company, OYL issued a standby letter of credit in the amount
of L17.0 million which supports the J&E Hall L17.0 million revolving credit
facility. OYL has also issued a $6.0 million letter of credit which supports a
revolving line of credit facility for the Company's subsidiary in Canada. No
fees were paid to OYL in connection with either letter of credit.
 
    The Company also has available letter of credit facilities totaling $25
million that are supported by letters of credit from OYL which were fully
utilized at June 30, 1997 and June 30, 1996. The commitments made under these
new facilities expire in March 1998, but may be extended annually for successive
one year periods with the consent of OYL and the banks providing the facilities.
No fees were paid to OYL in connection with the letter of credit facilities.
 
    In March 1995, the Company transferred its Singapore HVAC business to McQuay
Air Conditioning (Singapore) Pte. Ltd., a subsidiary of OYL. Assets including
motor vehicles, office equipment, furniture and fixtures, inventory, deposits
and prepayments were transferred with the business. The business was transferred
for a consideration of approximately $323,000 which was equal to its net book
value.

    EMPLOYEE BENEFIT PLANS
 
    EQUITY PARTICIPATION PLAN.  Effective January 1, 1991 the Company
established an Executive Employment and Compensation Plan (the "Equity
Participation Plan") and entered into Executive Employment and Compensation
Agreements with certain executive officers of the Company including Messrs.
Boehrs and Bailey (each of such executive officers is referred to herein as a
"NEPI Holder"). Under the Equity Participation Plan the Company agreed to
provide each such officer a contingent net equity participation interest (a
"NEPI Interest") in the Company under certain circumstances as follows: Mr.
Boehrs--0.4% and Mr. Bailey--0.5%.
 
    Pursuant to the Equity Participation Plan, as modified effective May 2, 1994
and in connection with the OYL Acquisition, 10% of each NEPI Holder's NEPI
Interest is designated a Reserve Amount and 90% of each NEPI Holder's NEPI
Interest has been paid or is payable by the Company to the NEPI Holder pursuant
to the following formula: one-third on May 2, 1994; one-third on May 2, 1995;
and one-third on May 2, 1996. On April 29, 1994 the Company established and
funded an irrevocable trust for the purpose of making such NEPI Interest
payments to NEPI Holders in due course. On May 2, 1996 the final distributions
were made from the trust.
 
    Under the terms of the Equity Participation Plan, as modified, each NEPI
Holder's Reserve Amount is subject, pro rata and severally not jointly, to
claims for certain indemnifications in connection with the OYL Acquisition. See
"Certain Transactions".
 
    RETIREMENT PLAN.  Effective April 3, 1982, the Company adopted the
Predecessor Company Retirement Plan (the "Retirement Plan"), which was amended
as of January 1, 1991 and further amended as of May 1, 1991 and December 31,
1991. The Retirement Plan has been maintained for the benefit of certain
salaried and hourly employees of the Company. Effective January 1, 1989,
benefits for most salaried participants in the Retirement Plan were frozen as of
December 31, 1988.
 
    Normal retirement age under the Retirement Plan is age 65. A participant's
annual rate of pension commencing after retirement is determined based on a
number of factors, including that participant's earnings, years of service and
contributions.
 
    The annual benefit amount, commencing at normal retirement age and payable
as a single life annuity, under the Retirement Plan for Messrs. Boehrs and
Bailey is approximately $1,777, and $2,514, respectively.
 
    SENIOR EXECUTIVE SEVERANCE PLAN.  Effective April 26, 1994 the Company
established a Senior Executive Severance Plan (the "Severance Plan") and,
pursuant thereto, entered into senior executive severance agreements with
certain executive officers of the Company including Messrs. Boehrs and Bailey.
Pursuant to the Severance Plan and the applicable agreements, upon involuntary
termination without good cause of such executive officer, the executive officer
will be entitled to receive his base salary as then in effect for a maximum
period of 12 months and cash in respect of certain retirement benefits. Pursuant
to such agreements, involuntary termination "without good cause" is defined to
include (i) any termination that does not result from material dishonesty,
significant fraud, willful negligence or gross and material malfeasance
detrimental to the Company or (ii) any requirement that the executive be based
or perform services at a new location, a material change in the position,
duties, authority or responsibilities of the executive or any decrease in the
executive's compensation.
 
    SEVERANCE AGREEMENT.  Effective July 31, 1997, the Company entered into a
Separation of Employment Agreement, General Release and Consulting Agreement
with Barton L. Bailey, the former Vice President of Human Resources of the
Company. Pursuant to the Severance Agreement, the Company is obligated to (i)
pay Mr. Bailey $169,110 as severance pay, in 12 monthly installments and
maintain certain
 
                                       56
<PAGE>
of his employee benefits until July 31, 1998, (ii) provide Mr. Bailey
outplacement services for three months, (iii) compensate Mr. Bailey for the cost
of real estate commissions on the sale of his principle residence, and (iv)
provide Mr. Bailey all benefits due him under the terms of the Executive Salary
Continuation Agreement which are fully vested and nonforfeitable. Further, Mr.
Bailey and the Company have entered into a consulting arrangement pursuant to
which Mr. Bailey has agreed to perform 40 hours per week of consulting services
for the Company until August 31, 1997 for which the Company will pay Mr. Bailey
$4,000 for the period plus $100 per hour for each hour Mr. Bailey works in
excess of 40 hours per week. Consulting requirements subsequent to August 31,
1998 will be mutually agreed upon at a rate of $100 per hour.
 
    SALARY CONTINUATION PLAN.  Effective January 1, 1990, the Company
established an Executive Salary Continuation Plan (the "Salary Continuation
Plan") for certain executive officers and key employees of the Company which
provides for compensation in the event of retirement or death.
 
    In the event a participant retires after he attains the age of 65 the
Company is required to pay to the participant a specified amount ($50,000 per
year in the case of each of Messrs. Boehrs and Bailey) until the earlier of (i)
the date of death of the participant or (ii) the first day of the month
following the ninth anniversary of the date of retirement of the participant.
The Salary Continuation Plan further provides for adjustments in the event of
early retirement. In the event the participant becomes totally disabled or is
terminated involuntarily without good cause, the participant will remain
eligible for the benefits. In the event of the death of a participant while
actively employed by the Company, the Company will make such payments to the
designated beneficiary of the participant.
 
    STOCK OPTION PLAN
 
    In 1997, the Company adopted a Stock Option Plan which provides for the
grant of non-qualified stock options to certain members of management and key
employees to purchase the common stock of the Company's parent AAF-McQuay Group
Inc. The Company anticipates the granting of options under the stock option plan
during fiscal year 1998. The related impact to the Statement of Operations will
be based on an independent valuation of the Company at or near the grant date.
 
    COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    Mr. Hunter is the only officer or employee of the Company who participated
in deliberations of the Company's Board of Directors concerning executive
officer compensation during the last fiscal year.

ITEM 13. CERTAIN RELATIONSHIP AND RELATED TRANSACTIONS
 
    In January 1995, OYL loaned $10 million to the Company in exchange for which
the Company issued a promissory note in the principal amount of $10 million in
favor of OYL. In March 1995, the promissory note was transferred to the Company
as an additional capital contribution.
 
    In connection with the acquisition of J&E Hall, which is now a wholly-owned
subsidiary of the Company, OYL issued a standby letter of credit in the amount
of L17.0 million which supports the J&E Hall L17.0 million revolving credit
facility. OYL has also issued a $6.0 million letter of credit which supports a
revolving line of credit facility for Company subsidiaries in Canada. No fees
were paid to OYL in connection with either letter of credit.
 
    The Company also has available letter of credit facilities totaling $25
million that are supported by letters of credit from OYL which were fully
utilized at June 30, 1997 and June 30, 1996. The commitments made under these
new facilities expire in March 1998, but may be extended annually for successive
one year periods with the consent of OYL and the banks providing the facilities.
No fees were paid to OYL in connection with the letter of credit facilities.
 
    In March 1995, the Company transferred its Singapore HVAC business to McQuay
Air Conditioning (Singapore) Pte. Ltd., a subsidiary of OYL. Assets including
motor vehicles, office equipment, furniture and fixtures, inventory, deposits
and prepayments were transferred with the business. The business was transferred
for a consideration of approximately $323,000 which was equal to its net book
value.
 
    In connection with the OYL Acquisition, the Company issued an $11.5 million
promissory note to Mr. Snyder, Mr. Caolo and the following holders of contingent
net equity participation interests in the Company: Mr. Bailey, Mr. Boehrs, James
F. Brum, Dick W. Driggs, Norbert O. Grohmann, Bruce E. Hebert and Mr. Tambornino
(each a "NEPI Holder") all of whom were officers of the Company prior to the OYL
Acquisition. Payment of the promissory note is secured by an $11.5 million
irrevocable standby letter of credit. The promissory note bears interest
semi-annually at a rate of up to six percent and matures on May 2, 1999. The
principal amount of the promissory note is subject to offset for claims for
indemnification on certain matters. Any such offset would be allocated 88.6% to
Mr. Snyder, 7.6% to Mr. Caolo and the balance among the NEPI Holders. The
principal amount of the promissory note becomes subject to offset claims only to
the extent that indemnification claims, less recoveries from third parties ("Net
Indemnification Claims"), exceed $5.8 million (the "Deductible Amount") in the
aggregate. To the extent that Net Indemnification Claims exceed the Deductible
Amount and the principal amount of the promissory note, such claims are required
to be paid by Mr. Snyder up to an additional $6.5 million in the aggregate.
 
    The Company has entered into trademark license and royalty agreements with
O.Y.L. Manufacturing Company SDN BHD ("OMC") (the "OMC Agreement"), Shenzhen
O.Y.L. Electrical Co. Ltd. ("Shenzhen") (the "Shenzhen Agreement") and P.T.
O.Y.L. Sentra Manufacturing ("PT OYL"). Pursuant to such Agreements, the Company
has granted OMC, Shenzhen and PT OYL, respectively, nonexclusive,
nontransferable rights and licenses to use the trademark "McQuay" in connection
with the sale and marketing of certain products exclusively through Shenzhen's,
OMC's and PT OYL's respective international distribution networks. In exchange
for such grants, OMC, Shenzhen and PT OYL have each agreed to pay the Company
earned royalty payments ranging from 2% to 5% of the accumulated net sales of
such products. The Company has been paid or was owed $207,000 and $228,000
pursuant to the OMC Agreement, $81,000 and $39,000 pursuant to the Shenzhen
Agreement, and $27,000 and $3,000 pursuant to the PT OYL agreement for the years
ended June 30, 1997 and June 30, 1996, respectively. Each of OMC, Shenzhen, and
PT OYL are subsidiaries of OYL.
 
    In August 1995, the Company entered into an agreement with McQuay-Wuhan Air
Conditioning & Refrigeration Company Ltd. ("McQuay-Wuhan"), a joint venture of
Wuhan-New World Refrigeration Industrial Company Limited and McQuay Asia (Hong
Kong) Ltd., an OYL subsidiary, to license certain technology and trademarks for
use in the Peoples Republic of China in exchange for a royalty of 2%-3% of net
sales. Pursuant to such agreement, royalties from the first two years of the
contract will be accumulated and paid after the third year of the contract. Such
accumulated royalty payments will be made quarterly and the amount of such
payments will be dependent upon McQuay-Wuhan's financial condition.
 
    Hong Leong and its subsidiary companies, including OYL and the Company, have
a policy of buying from related companies whenever feasible. During fiscal years
ended June 30, 1997 and June 30, 1996
 
                                       59
<PAGE>
pursuant to this policy, the Company and various of its subsidiaries sold an
aggregate of approximately $16.3 and $14.4 million, respectively of the
Company's products to various OYL entities in the ordinary course of business.
Additionally during fiscal year 1997, the Company purchased approximately $3.3
million of product from OYL and its subsidiary companies in the ordinary course
of business. The Company does not expect a change in this policy and plans to
continue to buy from and sell to OYL and Hong Leong related entities in the
future.

    and

         (b)  this Amendment, each other Loan Document, the Credit Agreement
    as amended hereby and, upon the occurrence of the Fourth Amendment
    Effective Date, the Amended Credit Agreement are the legal, valid and
    binding obligations of the U.S. Borrower, each of its Subsidiaries

otherwise relating to any such accounts, contracts, contract rights, chattel
paper, documents, instruments, and general intangibles.

Mr. Barton L. Bailey

Dear Bart,

CONSULTING RELATIONSHIP

Following your separation from the Company, AAF-McQuay Inc. may be able to 
utilize your services in the role of a specialized consultant.

On the basis that a minimum base requirement will be for 40 hours of service 
during the month of August 1997, payment for that period will be $4,000.   
Any additional requirements during August 1997, above the 40 hours, will be 
compensated for at the rate of $100 per hour.

Requirements beyond the month of August 1997 will be identified, mutually 
agreed in writing and compensated for at a rate of $100 per hour.

We trust that you will find the above proposal satisfactory and look forward 
to a new relationship on the proposed terms.

Sincerely,




Joseph B. Hunter

                   SEPARATION OF EMPLOYMENT AGREEMENT,
                 GENERAL RELEASE AND CONSULTING AGREEMENT


This Separation of Employment Agreement, General Release and Consulting 
Agreement (herein "Agreement") is hereby entered into as of this 17th day of 
July 1997 between AAF-McQuay Inc., its parents, subsidiaries, affiliates, 
divisions, predecessors, purchasers, assigns, representatives and successors 
(hereinafter collectively referred to as "the Company") and Barton L. Bailey 
(hereinafter "Mr. Bailey"), who are collectively referred herein as the 
"Parties."

WHEREAS, the Parties now desire and agree to forever sever their employment 
relationship and to fully and finally resolve any and all existing or 
potential issues, claims, causes of action, grievances and disputes that do, 
or could relate thereto or arise out of that relationship or severance 
thereof, without any admission of liability or finding or admission that any 
of Mr. Bailey's rights, under any statute, claim or otherwise, were in any 
way violated.   In consideration of the mutual promises contained herein, and 
other good and valuable consideration as hereinafter recited, the receipt and 
adequacy of which is hereby acknowledged, the Parties, intending to be 
legally bound, agree as follows:

Separation and Severance

    a.   The Company and Mr. Bailey agree that Mr. Bailey's employment with 
         the Company will terminate effective July 31, 1997.   The Company
         agrees that it will pay Mr. Bailey $169,110 as severance pay, in
         twelve monthly payments of $14,092.50, less all lawful deductions for
         FICA, Medicare, and Federal State and local taxes, the adequacy of
         which is hereby acknowledged, commencing on September 1, 1997 and on
         the 1st day of each consecutive month thereafter until August 1, 1998.
         This Agreement terminates and supersedes the terms of the "Senior
         Executive Severance Agreement" executed by Mr. Bailey and the Company
         on April 26, 1994 including, but not limited to, the provision in
         Paragraph 1(a)(i) of that Agreement requiring Mr. Bailey to seek
         comparable employment opportunities over the twelve month period after
         his termination of employment from the Company.   The Company agrees
         that in the even of the death of Mr. Bailey all remaining payments
         under this paragraph will be paid to his beneficiaries.  The Company's
         obligation to pay these amounts is absolute and unconditional and shall
         not be affected by any circumstances, including, without limitation,
         any set-off, counterclaim, recoupment, defense or other right that the
         Company may have against him or anyone else.

    b.   The Company agrees to provide Mr. Bailey his current level of health 
         care benefits, group life insurance and long term disability until
         July 31, 1998 under the terms and conditions that applied to Mr. Bailey
         
<PAGE>

         immediately prior to his separation of employment from the Company.
         Mr. Bailey recognizes and agrees that for the purposes of the
         continuation coverage requirements of group health plans under the
         Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA"), as
         amended, and the group health provisions of any state law, a
         "qualifying event" and "applicable change in status" occurs on July 31,
         1998.   The Company further agrees to provide Mr. Bailey with
         continuation coverage under its group health plan at Mr. Bailey's
         expense until February 1, 1999, at which time he will commence
         participation in the Company's Retiree Medical Group Benefits Plan.
         The benefits under the Company's Retiree Medical Group Benefits Plan
         will be offered to Mr. Bailey on the same basis as is offered to other
         retirees.

    c.   The Company will provide an outplacement service for a three month 
         period and will compensate Mr. Bailey for the cost of real estate
         commissions on the sale of his principal residence.

    d.   The Company further agrees to retain Mr. Bailey as a consultant for
         specific projects as may be identified from time to time and as
         mutually agreed upon.

    e.   It is expressly understood that all benefits due Mr. Bailey under the
         terms of the Executive Salary Continuation Agreement are fully vested
         and nonforfeitable; that for the purposes of that Agreement, he will
         be treated as though he had been "terminated, involuntarily without
         good cause" and had remained in the employ of the Company through an
         Early Retirement date of February 1, 2003.

    f.   Mr. Bailey agrees that portions of the above-described consideration
         and payments from the Company are over and above that to which he is
         otherwise entitled and constitutes good and valid consideration.
