NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.  BASIS OF PRESENTATION

     The consolidated financial statements include the accounts of the Company
and all of its wholly-owned subsidiaries. All inter-company transactions have
been eliminated. The accompanying unaudited consolidated financial statements
have been prepared in accordance with generally accepted accounting principles
for interim reporting and with the instructions to Form 10-Q and Article 10 of
Regulation S-K. Accordingly, certain information and footnote disclosures
normally included in financial statements prepared in accordance with generally
accepted accounting principles have been omitted. For further information, refer
to the consolidated financial statements and footnotes thereto included in the
Company's Annual Report on Form 10-K (the "Annual Report") for the year ended
June 30, 1999. In the opinion of management, all adjustments (consisting of
normal recurring accruals) considered necessary for a fair presentation have
been included. The accompanying financial statements reflect the statements of
operations for the three months ended September 30, 1999 and 1998, the balance
sheets at September 30, 1999 and June 30, 1999, and the consolidated statements
of cash flows for the three months ended September 30, 1999 and 1998.

     The operating results for the three months ended September 30, 1999 are not
necessarily indicative of the operating results that may be expected for the
full year ending June 30, 2000. The Company's period end is the Saturday closest
to September 30. For clarity in presentation all periods presented herein are
shown to end on the last calendar day of the month. Certain reclassifications of
amounts in the consolidated financial statements have been made to reflect
comparability.

     During the first quarter of fiscal year 1999, the Company made a change
in accounting estimate related to its warranty provision and increased its
warranty provision by $2.5 million due to activity related to new product
introductions and discontinued product lines.

2.  INVENTORIES

     Inventories consist of the following:

</TABLE>

3.  NET OTHER (INCOME)EXPENSE

     During the first quarter of fiscal year 2000, the Company had expense of
$2.1 million compared to $4.8 million of income in the first quarter of fiscal
year 1999. In the first quarter of fiscal year 2000, the Company accrued a $1.3
million loss related to the sale of the commercial air conditioning and
refrigeration operation in France in October 1999. Additionally, in conjunction
with the Company's refinancing, discussed in Note 5, the Company wrote off
certain unamortized income and debt issuance costs resulting in a charge of
$318,000 in the first quarter of fiscal year 2000. In the first quarter of
fiscal year 1999 the Company recognized $2.9 million in other income as a result
of favorable developments in the IRS audit and the tax indemnification
settlement with former shareholders of the Company. The Company also recorded a
$1.5 million gain related to the termination of a pension plan in Canada. The
remaining components of other income and expenses resulted from foreign currency
and equity affiliate transactions.

4.  PROVISION FOR INCOME TAXES

     The tax provisions for the first quarters ended September 30, 1999 and
1998 are based on the estimated effective tax rates applicable for the full
years, and after giving effect to significant unusual items related
specifically to the interim periods. The difference between the Company's
reported tax provision, for the first quarters ended September 30, 1999 and
1998, and the tax provision computed based on U.S.

                                       7
<PAGE>

statutory rates is primarily attributable to nondeductible goodwill amortization
and unbenefitted foreign losses. Additionally, the Company's effective tax rate
for the first quarter ended September 30, 1998 reflects the effect of the
indemnification settlement agreement and the IRS settlement which was recognized
as income for financial reporting purposes but is not taxable for income tax
purposes.

5.  DEBT AND FINANCIAL INSTRUMENTS

     On September 30, 1999, as further discussed in the Company's Form 10K,
the Company entered into a new bank credit agreement. As a result of the bank
credit agreement refinancing that took place, the Company wrote off certain
unamortized debt issuance costs associated with the previous credit
agreement. In addition, the balance of the unamortized income from early
termination of the swap was eliminated. These actions resulted in net charge
to other (income) expense of $318,000 for the current quarter.

     The Company secures pricing on a portion of its copper and aluminum
requirements through forward contracts executed with certain suppliers. At
September 30, 1999, contracts for 5.7 million pounds of copper at an average
price of $0.71 per pound and 1.4 million pounds of aluminum at an average price
of $0.68 per pound were in place. These contracts have various expiration dates
through June 30, 2000.

6.  RESTRUCTURING

     As described in Note 10 of the Annual Report, the Company implemented
several restructuring plans throughout fiscal year 1999 in both the Commercial
Air Conditioning and Refrigeration and Filtration Products groups. Through
September 30, 1999, the Company has spent $3.4 million of the $5.2 million
restructuring reserve recorded in fiscal year 1999 primarily for severance
arrangements. The Company continues to implement actions in accordance with the
restructuring plan.

7.  CONTINGENCIES

     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, among other things, impose potential liability on the Company for
the cost of remediation of 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 in note 14 of the Annual Report 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 upon the completion of a formal study or the
Company's commitment to a formal plan of action.

     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.

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
               AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

      NET SALES for the first quarter of fiscal year 2000 were $225.1 million.
This represents a decrease of $26.3 million, or 10.5%, from $251.4 million for
the first quarter of fiscal year 1999. The Company estimates that approximately
$17.3 million, or 65.9%, of the decrease is attributable to having one less week
of sales in the first quarter of fiscal year 2000 as compared to the first
quarter of fiscal year 1999. The first quarter of fiscal year 2000 reflects a 13
week period as compared to a 14 week period for the first quarter of fiscal year
1999.

     COMMERCIAL AIR CONDITIONING AND REFRIGERATION GROUP net sales decreased
$18.9 million, or 11.3%, to $147.9 million in the first quarter of fiscal
year 2000 as compared to the first quarter in fiscal year 1999. The Company
estimates that approximately $11.4 million, or 60.3%, of the decrease is
attributable to one less week of sales in the first quarter of fiscal 2000 as
compared to the first quarter of fiscal 1999. The remaining decrease of $7.5
million is primarily attributable to decreased sales in the chiller products
and terminal air conditioning systems business units. Chiller product net
sales decreased 16.9% in the first quarter of fiscal year 2000 compared to
the first quarter of fiscal year 1999 as a result of the restructuring of the
chiller business unit. Terminal air conditioning products net sales decreased
16.0% in the first quarter of fiscal 2000 as compared to the first quarter of
fiscal year 1999 as a result of the product rationalization in North America
and a related market reaction as a result of the changes in product
offerings. The sales decreases in the chiller products and terminal air
conditioning products business units were partially offset by increased sales
in the service and parts business units as a result of strong demand for
replacement parts, and increased sales from the operations in Italy and Dubai.

     Backlog for the Commercial Air Conditioning and Refrigeration Group was
$135.0 million at September 30, 1999 as compared to $125.5 and $133.7 million at
September 30, 1998 and June 30, 1999, respectively.

     FILTRATION PRODUCTS GROUP net sales were $77.7 million in the first
quarter of fiscal year 2000, a decrease of $10.7 million, or 12.1%, from
$88.4 million in the first quarter of fiscal year 1999. The Company estimates
that approximately $6.0 million, or 55.8%, of the decrease is attributable to
one less week of sales in the first quarter of fiscal 2000 as compared to
fiscal 1999. The remaining decrease of $4.7 million is attributable to slow
MFAS sales in the United States due to soft market conditions and a decrease
in air pollution control sales in Europe.

     GROSS PROFIT was $60.0 million or 26.6% of sales for the first quarter of
fiscal year 2000 versus $67.5 million or 26.9% of sales for the first quarter of
fiscal year 1999. In the Commercial Air Conditioning and Refrigeration Group,
gross profit as a percentage of sales was 24.5% in the first quarter of fiscal
year 2000 as compared to 25.4% of sales in the first quarter of fiscal year
1999. This decrease in gross margin resulted primarily from lower margin sales
of chiller and air handling products. The Filtration Products Group's gross
profit as a percentage of sales increased in the first quarter from 28.4% in
fiscal year 1999 to 30.5% in the first quarter of fiscal year 2000. This
increase resulted from improved manufacturing performance.

     OPERATING EXPENSES were $52.9 million or 23.5% of sales for the first
quarter of fiscal year 2000 as compared to $59.5 million or 23.7% of sales
for the first quarter of fiscal year 1999. The Company estimates that
approximately $4.1 million, or 61%, of the decrease is attributable to one
less week of operating expenses in the first quarter of fiscal 2000 as
compared to the first quarter of fiscal 1999. The remaining decrease of $2.5
million is primarily attributable to a reduction in warranty expense offset
by an increase in depreciation expense related to the new Enterprise Resource
Planning systems.

     INCOME FROM OPERATIONS for the first quarter of fiscal years 2000 and 1999
was $7.1 and $8.0 million, respectively. As a percentage of sales, income from
operations remained flat at 3.2% of sales for both of the first quarters of
fiscal years 2000 and 1999. The Commercial Air Conditioning and Refrigeration
Group had a decrease in income from operations from $3.8 million, or 2.3% of
sales, to $2.2 million, or 1.5% of sales, for the first quarter of fiscal year
2000 as compared to the first quarter of fiscal year 1999, respectively. The


                                       10
<PAGE>


Filtration Products segment had an increase in income from operations from $4.5
million, or 5.1% of sales, to $5.3 million, or 6.8% of sales, for the first
quarter of fiscal year 1999 as compared to the first quarter of fiscal year
2000.

     NET INTEREST EXPENSE was $5.9 million in the first quarter of fiscal year
2000 as compared to $6.5 million for the first quarter of fiscal year 1999. This
decrease is primarily attributable to having one less week of activity in the
first quarter of fiscal year 2000 as compared to the first quarter of fiscal
year 1999.

     NET OTHER (INCOME) EXPENSE for the first quarter of fiscal year 2000 was
expense of $2.1 million compared to income of $4.8 million in the first
quarter of fiscal year 1999. See Note 3 to the unaudited consolidated
financial statements for further discussion.

     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.
During the first quarter of fiscal year 2000, funds generated by operating
activities were $4.0 million as compared to funds used by operating activities
of $1.6 million in the prior fiscal year for the comparable period. During the
first quarter of fiscal year 2000, cash used in investing activities was $2.3
million, which represents a $2.9 million reduction from the prior year first
quarter. The reduction in capital spending stems from recent completion of the
information technology enhancement project. On September 30, 1999, the Company
refinanced its Bank Credit Agreement with a New Term Loan of $30 million and a
new Revolving Credit Facility of $90 million ("New Bank Credit Agreement"). The
New Bank Credit Agreement has a three-year term, was used to retire all
obligations under the previous Bank Agreement and is designed to provide added
flexibility and borrowing availability. The New Bank Credit Agreement also
provides favorable interest rates and other fees compared to the previous Bank
Credit Agreement. At the closing date for the New Bank Credit Agreement and at
the end of the first quarter, remaining borrowing availability under the new
Revolving Credit portion of the New Bank Credit Agreement was $32 million. Total
net payments on long term debt for the first quarter were $8.1 million which is
a result of new borrowing under the New Term Loan of $30.0 million, repayment of
the balance on the previous Bank Term Loan of $37.3 million and other long term
debt payments of $0.8 million. Cash of $10.3 million was provided by net
borrowing under short term borrowing arrangements for long term debt repayment
and working capital requirements during the period.

     A short-term credit facility provided to a subsidiary of the Company is
supported by a letter of credit from OYL which expires on September 30, 2000. In
addition, the Company has secured certain domestic letter of credit facilities
totaling $13.5 million that are supported by a letter of credit from OYL which
expires on March 21, 2000. Each of these support arrangements may be extended
for additional time periods with the consent of OYL and the banks providing the
facilities.

     On an ongoing 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 businesses or exit
low value added or non-synergistic operations. In October 1999, the Company
sold the commercial air conditioning and refrigeration operation in France
with the proceeds used to reduce debt. The Company does not believe that the
sale of the commercial air conditioning and refrigeration operation in France
will have a material effect on the Company's future financial results.

     Management believes, based upon current levels of operations and forecasted
earnings, that cash flow from operations, together with borrowings under the New
Bank Credit Agreement 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



                                       11
<PAGE>

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.

   YEAR 2000

     The Company established a formal Year 2000 program during fiscal year
ending June 30, 1998, which began with a worldwide assessment and development
of a central data base containing an inventory of the risk elements
associated with the Year 2000 issue for each of the Company's operations. The
Company also appointed an overall project coordinator and established an
executive review process. Prior to establishing a formal Year 2000 management
process, the Company had already decided to replace substantially all of its
old systems with new state-of-the-art Enterprise Resource Planning (ERP)
systems. The Company estimates expenditures for the new systems have
aggregated approximately $27.0 million through project completion at month-end
September 1999. Expenditures for additional remedial actions beyond those
required to install new systems are managed by the individual business units
and recognized in operating expenses. The Company's management believes that
modernizing its information systems is critical for the Company's stable and
efficient growth, and it is the basis of the Company's strategy for resolving
its Year 2000 issues.

     During May 1998, the Company began its review of the products it
manufactures and sells, and the Company believes that its products, including
the control systems provided by the Company, are Year 2000 compliant. The
Company has also identified third parties upon whom the Company is dependent for
products or services, and commenced actions during fiscal year ending June 30,
1998, to ensure those products and services are compliant and will not be
interrupted as a result of Year 2000.

    The scheduled Year 2000 activities and current status are summarized in the
chart below:

         * Complete indicates that the key components are complete, with minor
           follow-up tasks still in process.

     The final Year 2000 activities are currently on schedule. The Company has
successfully implemented the scheduled ERP projects and systems upgrades.

     Failure by the Company's third party suppliers and/or service providers to
produce or deliver critical components or to transport services could cause
disruption in the Company's ability to manufacture and/or deliver timely its
products to its customers, which could result in increased expenses, reduced
billings and potential litigation. The precise costs associated with such risks
are difficult to predict at this time. The Company currently is developing its
Business Continuity and Contingency Plans, for each of its businesses, in the
event that internal, external, or systemic failures occur on or about January 1,
2000.



                                       12

     The Company believes the Year 2000 activities are adequate to address the
Year 2000 risks faced by the Company; however, there can be no assurance that
the Year 2000 procedures and activities, even if completed, will be adequate to
address the Company's Year 2000 risk.

EURO CONVERSION

     Management has initiated an internal analysis of and planning for the
effect the Euro will have on the operating and financial condition of the
Company. The Euro is not expected to have a material effect on the Company's
operating results or competitive position. The Company's financial systems are
Euro compliant and opportunities will continue to be investigated for
European-wide system infrastructures.
