opportunity for a maximum additional payout of $3.75 million based upon the
future earnings performance of the Evap business. The acquisition was accounted
for as a purchase and goodwill of $3.0 million, which is being amortized over 20
years, was recorded as part of the transaction.

NOTE 6 - SUBSEQUENT EVENT

On October 22, 1999, the Company announced its intent to strategically realign
its business to significantly grow its presence in the automotive aftermarket.
The key steps in this realignment include the evaluation of strategic
alternatives with respect to the OEM Heat Transfer and Specialty Metal
Fabrication segments, the development of a 223,000 square foot manufacturing
facility for the re-manufacturing of automotive air conditioning compressors and
the completion of a new 6-millimeter condenser design to be produced on a new
manufacturing line in the Company's existing Mexico facility.

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

OPERATING RESULTS

THREE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 1998

         Total net sales for the three months ended September 30, 1999 increased
4.5% to $71.6 million compared with $68.5 million for the three months ended
September 30, 1998. Sales in the Aftermarket Heating and Cooling Systems segment
decreased by $0.5 million, or 0.9%, from the comparable 1998 period, reflecting
lower radiator core, heater and condenser sales, offset by increased complete
radiator sales and air conditioning parts sales due to the acquisitions of Evap
in August 1998 and A/C Plus in February 1999. Sales in the OEM Heat Transfer
Systems segment increased by $0.4 million, or 3.9%, compared with the comparable
1998 quarter, due to an increase in volume resulting from the strong Class 8
truck and specialty vehicle markets. Sales in the Specialty Metal Fabrication
segment increased by $3.1 million, or 30.2%, compared with the comparable 1998
quarter, due to an increase in sales of specialty fabricated enclosures to
telecommunications customers while vehicle conversion revenues were flat.

         Gross margins improved to 24.7% for the three months ended September
30, 1999 from 23.9% during the three months ended September 30, 1998. The
improvement was driven by gross margin improvements in the Aftermarket Heating
and Cooling Systems segment, reflecting the sales of higher margin air
conditioning parts by the newly acquired air conditioning parts companies as
well as lower material costs and improved manufacturing efficiencies. In the OEM
Heat Transfer Systems segment, actions the Company has taken to improve
operational efficiencies have resulted in the generation of positive gross
margins during the three months ended September 30, 1999 versus negative gross
margins in the comparable prior year period. Gross margins in the Specialty
Metal Fabrication segment improved in the third quarter of 1999 compared with
1998 primarily due to increased utilization and fixed cost coverage at the new
Plano, Texas metal fabrication facility.

         Selling, general and administrative ("SG&A") expenses increased by $0.3
million or 2.0% over the prior year three month period. SG&A expenses increased
primarily due to the inclusion of a full quarter of expenses in 1999 associated
with Evap and A/C Plus operations. SG&A expenses also increased approximately
$0.3 million due to the settlement in the 1999 third quarter of an
employment-related lawsuit, offset by a reduction in health insurance costs.
SG&A expenses declined as a percentage of sales from 19.8% to 19.4%.

         Net interest expense increased $0.2 million in the three months ended
September 30, 1999 compared with the three months ended September 30, 1998 due
to higher debt levels associated with the acquisition of Evap and A/C Plus, and
higher working capital levels related to the air conditioning parts business.

         The Company's effective tax rate of 43.3% for the three months ended
September 30, 1999, is comprised of the U.S. Federal income tax rate plus the
estimated aggregate effective rate for foreign, state and local income taxes,
and increased from the three months ended September 30, 1998 rate of 40.8% to
reflect a higher level of non-tax deductible expenses expected in 1999 and a
valuation allowance associated with a net operating loss carryforward for the
Company's Canadian vehicle conversion operation.


                                       10
<PAGE>   11
         Net income for the three months ended September 30, 1999 was $1.5
million, or $0.23 per basic common share and $0.21 per diluted common share,
compared with net income of $1.1 million, or $0.17 per basic common share and
$0.16 per diluted common share for the three months ended September 30, 1998.
Excluding the effect of costs associated with the settlement of the employment
related lawsuit, earnings for the three months ended September 30, 1999 were
$1.6 million, or $0.25 per basic common share and $0.23 per diluted common
share.

NINE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
1998

         Total net sales for the nine months ended September 30, 1999 increased
7.7% to $199.0 million compared with $184.7 million for the nine months ended
September 30, 1998. Sales in the Aftermarket Heating and Cooling Systems segment
increased by $10.0 million, or 8.2%, from the comparable 1998 period, reflecting
the sales contribution from Evap and A/C Plus and volume increases in the
complete radiator and heater product lines, partially offset by lower sales of
radiator cores and condensers. Sales in the OEM Heat Transfer Systems segment
declined by $0.5 million, or 1.7%, compared with the comparable 1998 period,
primarily as a result of higher level of sales in the first quarter of 1998
related to the catch up of overdue 1997 orders. Sales in the Specialty Metal
Fabrication segment increased by $4.8 million, or 13.9%, compared with the
comparable 1998 period, primarily due to an increase in sales of specialty
fabricated enclosures to telecommunications customers.

         Gross margins for the nine months ended September 30, 1999 were 25.4%
compared with 23.6% for the nine months ended September 30, 1998. The
improvement reflects the contribution of higher margin air conditioning parts
sales from Evap and A/C Plus, coupled with lower material costs, higher volume
in complete radiators, and improved manufacturing efficiencies in the
Aftermarket Heating and Cooling Systems segment. Gross margins in the Specialty
Metal Fabrication business declined due to lower margins from vehicle
conversions offset by better utilization of fixed costs associated with the new
Plano, Texas metal fabrication facility. Actions the Company has taken to
improve operational efficiencies in the OEM Heat Transfer Systems business
generated positive gross margins for the nine months ended September 30, 1999,
compared with negative margins in the prior year period.

         Selling, general and administrative expenses for the nine months ended
September 30, 1999, were $39.7 million compared with $37.1 million for the
comparable period in 1998, primarily as a result of the inclusion of expenses
associated with Evap and A/C Plus, but were essentially flat as a percentage of
sales. Included in SG&A expenses for the nine months ended September 30, 1999
were costs of approximately $0.3 million related to the settlement of an
employment related lawsuit, which is offset by a reduction in health insurance
costs.

         Plant closure costs of approximately $0.3 million related to the
closure of the Company's Philadelphia, Pennsylvania and Atlanta, Georgia
replacement automotive condenser manufacturing plants were recognized in the
nine months ended September 30, 1999.

         Net interest expense was $3.2 million for the nine months ended
September 30, 1999 compared with $2.5 million in the nine months ended September
30, 1998 due to higher debt levels associated with the acquisition of Evap and
A/C Plus, higher working capital levels and to support the air conditioning
parts business.


                                       11
<PAGE>   12
         During the nine months ended September 30, 1999, the Company recognized
a non-recurring, non-cash deferred tax benefit of $2.9 million related to the
change in the organizational structure of its GO/DAN Industries operation from a
partnership to a corporation. The Company's effective tax rate of 42.8% for the
nine months ended September 30, 1999, which does not include the impact of the
non-recurring, non-cash deferred tax benefit, is comprised of the U. S. Federal
income tax rate plus the estimated aggregate effective rate for foreign, state
and local income taxes and increased from 40.8% from the nine months ended
September 30, 1998 to reflect a higher level of non-tax deductible expenses
expected in 1999 and a valuation allowance associated with a net operating loss
carryforward for the Company's Canadian vehicle conversion operation.

         Net income for the nine months ended September 30, 1999 was $7.1
million, or $1.08 per basic common share and $1.00 per diluted common share,
compared with net income of $2.4 million, or $0.37 per basic common share and
$0.36 per diluted common share, in the nine months ended September 30, 1998.
Excluding the effect of plant closure costs, the lawsuit settlement costs, and
the non-recurring, non-cash deferred tax benefit, net earnings for the nine
months ended September 30, 1999 were $4.6 million, or $0.70 per basic common
share and $0.65 per diluted common share.

FINANCIAL CONDITION
LIQUIDITY AND CAPITAL RESOURCES

         In July 1998, the Company entered into a Revolving Credit Agreement
(the "Revolving Credit Agreement") with five banking institutions, which
provides for secured borrowings or the issuance of letters of credit in an
aggregate amount not to exceed $75 million. The Revolving Credit Agreement is
secured by a blanket first perfected security interest in substantially all of
the Company's assets plus a pledge of the stock of the Company's subsidiaries.
The Revolving Credit Agreement expires on July 1, 2003. The security interest in
the Company's assets and the pledge of the Company's subsidiaries' stock are
eligible for release if the Company achieves certain senior debt ratings or if
certain financial ratios are met and maintained.

         Available borrowings under the Revolving Credit Agreement are
determined by a borrowing base consisting of the Company's eligible (i) accounts
receivable, (ii) inventory and (iii) fixed assets, as adjusted by an advance
rate. The aggregate amount of borrowings under the Revolving Credit Agreement is
automatically reduced by $0.5 million at the end of each calendar quarter
through June 30, 1999; by $1.25 million at the end of each calendar quarter
through June 30, 2000, and by $1.5 million at the end of each calendar quarter
through June 30, 2003. The Revolving Credit Agreement bears interest at variable
rates based, at the Company's option, on either (a) a Eurodollar loan rate, plus
an applicable margin based upon the ratio of the Company's total funded debt to
earnings before interest, taxes, depreciation and amortization ("EBITDA"), or
(b) the higher of (i) the BankBoston, N. A. base lending rate or (ii) one-half
of one percent above the Federal Funds Effective Rate, as defined, plus an
applicable margin based upon the ratio of the Company's total funded debt to
EBITDA. A commitment fee of .25% or .375% based upon the ratio of the Company's
total funded debt to EBITDA on the average daily unused portion of the Revolving
Credit Agreement is payable quarterly, in arrears.

         The Revolving Credit Agreement contains financial covenants which,
among other things, require the maintenance of a minimum tangible net worth and
debt service coverage and a maximum level of debt to EBITDA and debt to net
worth, as well as covenants which place limits on dividend payments in excess of
$2.0 million per year and capital expenditures in excess of 140% of such year's
depreciation expense.


                                       12
<PAGE>   13
         At September 30, 1999, borrowings totaling $47.8 million were
outstanding under the Revolving Credit Agreement. The Company also has $13.0
million of borrowings under floating rate industrial revenue bonds, of which
$8.0 million matures in the year 2010 and $5.0 million matures in the year 2013.
The bonds bear interest based upon a short-term tax-exempt bond index.
Outstanding letters of credit totaled approximately $17.5 million at September
30, 1999, of which $13.0 million supported borrowings under floating rate
industrial revenue bonds.

         During the nine months ended September 30, 1999, the Company required
$8.1 million of cash to support its operations as a result of a $16.3 million
increase in inventory levels and a $10.0 million increase in accounts receivable
to support seasonal working capital requirements and its expansion in the air
conditioning parts and fabricated metal enclosures businesses. Cash was used to
reduce accounts payable and accrued expenses by $8.1 million.

         Capital spending during the nine months ended September 30, 1999
totaled $6.1 million and the acquisition of A/C Plus, including transaction
costs, required $2.4 million of cash. The Company paid three $0.05 per share
cash dividends, totaling $1.0 million in the aggregate during the nine months
ended September 30, 1999. Net borrowings under the Revolving Credit Agreement to
finance the operating and other cash requirements of the Company increased by
$18.1 million from December 31, 1998.

         Until at least the mid-second quarter of the 2000 fiscal year, the
liquidity and ordinary capital needs of the Company are expected to be met from
operations. However, the Company does not believe that its cash flow from
operations together with borrowings under its current Revolving Credit Agreement
will be adequate to meet its ordinary capital expenditures and working capital
requirements during the second and third quarters of fiscal 2000 due primarily
to the need to build inventory for its seasonal Aftermarket Heating and Cooling
Systems segment. Furthermore, the Company believes that the amount of borrowings
available under the Revolving Credit Agreement will not be sufficient to meet
the capital needs for major growth initiatives. The Company intends to explore
financing alternatives, including increasing availability under its Revolving
Credit Agreement, obtaining a new line of credit with sufficient borrowing
capacity or securing additional sources of capital. It is also possible that
additional liquidity may be obtained through the disposition of business
operations, although there can be no assurance that any such disposition would
occur on a timely basis, or at all. No assurance can be given that the Company
will be successful in increasing its availability under its Revolving Credit
Facility, obtaining a new line of credit or securing additional sources of
capital on favorable terms, or at all.

IMPACT OF THE YEAR 2000 ISSUE

         The Year 2000 issue results from computer system software using only
two digits rather than four digits to define the applicable year for a
transaction. Such software may not recognize a date identified as "00" or may
assume the year to be 1900 instead of 2000. In the worst case, this may result
in system failure or miscalculation causing disruption of operations, including
but not limited to, a temporary inability to process transactions, send
invoices, generate disbursement checks or engage in similar normal business
activities.

         The Company's Year 2000 initiative consists of: (i) performing an
inventory of all computer, facility and manufacturing equipment and external
business partners which may be Year 2000 sensitive; (ii) assessing


                                       13
<PAGE>   14
that inventory for Year 2000 compliance; (iii) developing a plan to remediate or
replace non Year 2000 compliant inventory items; and (iv) the implementation of
that plan, including remediation, replacement, testing and contingency
arrangements, as necessary.

         The Company has identified an information systems platform which is
Year 2000 compliant and to which the majority of current systems employed by the
Company have been converted. All assessment and planning tasks have been
completed. Remediation and testing of mission critical systems has also been
completed. Remaining remediation and testing tasks for non-mission critical
systems is planned for completion by the end of October 1999. Testing and
contingency planning, as necessary, will continue throughout the rest of the
year. Hardware, software and other capitalizable costs will be capitalized and
depreciated over the useful life of the systems. All other project costs will be
expensed as incurred. The total cost of the Year 2000 project is currently
estimated to be $3.2 million, which is $0.7 higher than original estimates due
to additional system conversion costs and associated labor costs identified
through the assessment process. A total of $2.2 million of the $3.2 million
estimate are for capitalizable hardware and software costs. To date, the Company
has spent approximately $2.9 million on this project, of which $2.0 million was
for capitalizable hardware and software costs.

         During 1998, the Company initiated formal communications with its
information technology hardware and software providers, its significant vendors,
service providers, lenders and large customers to determine the extent to which
it is vulnerable to the Year 2000 issue externally. The Company believes that
with the completion of its Year 2000 initiatives, as scheduled, the possibility
of significant interruptions of normal operations should be significantly
reduced. However, no assurance can be given that the systems of other companies
on which the Company relies will be Year 2000 compliant on a timely basis, that
the Year 2000 systems of other companies will be compatible with the Company's
system or that external Year 2000 issues would not have a material impact on the
Company's operations. Contingency plans are being developed as necessary, to
mitigate the impact of non-year 2000 compliant external issues which, in the
worst case, may result in source of supply issues with suppliers or the
inability of customers to order product.
