                            CECO ENVIRONMENTAL CORP.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (unaudited)
- --------------------------------------------------------------------------------

1.  The accompanying unaudited consolidated financial statements of CECO
    Environmental Corp. (the "Company") and subsidiaries have been prepared in
    accordance with accounting principles generally accepted in the United
    States of America. In the opinion of management, the accompanying unaudited
    condensed consolidated financial statements of the Company contain all
    adjustments (consisting only of normal recurring accruals) necessary to
    present fairly the financial position as of March 31, 2001 and the results
    of operations and cash flows for the three-month periods ended March 31,
    2001 and 2000. The results of operations for the three-month period ended
    March 31, 2001 are not necessarily indicative of the results to be expected
    for the full year.

    These financial statements should be read in conjunction with the audited
    financial statements and notes thereto in the Company's Annual Report on
    Form 10-KSB filed with the Securities and Exchange Commission.

    Recent accounting pronouncements - On January 1, 2001, the Company adopted
    Statement of Financial Accounting Standard ("SFAS") No. 133, "Accounting for
    Derivative Instruments and Hedging Activities," as amended by SFAS No. 138,
    "Accounting for Certain Derivative Instruments and Certain Hedging
    Activities". SFAS No. 133 establishes accounting and reporting standards for
    derivative instruments and for hedging activities. It requires that all
    derivative instruments, including those embedded in other contracts, be
    recognized as either assets or liabilities and that those financial
    instruments be measured at fair value. The accounting for changes in the
    fair value of derivatives depends on their intended use and designation.

    The Company has an interest rate swap agreement to manage its exposure to
    interest rate fluctuations. The estimated fair value of this agreement at
    March 31, 2001 was a net payable of $350,000 and is included in other
    non-current liabilities on the accompanying balance sheet. The interest rate
    swap agreement meets the criteria for hedge accounting under SFAS No. 133
    and accordingly, the cumulative after-tax fair value of the interest rate
    hedges is included in other comprehensive loss in the first quarter of 2001.
    Other comprehensive loss for the quarter ended March 31, 2001 was $550,000,
    which included the SFAS No. 133 transition obligation required during the
    first quarter of 2001.


2.  Inventories consisted of the following:

Revenues

Consolidated total revenue for the first three months ended March 31, 2001, was
$19.8 million versus comparable 2000 total revenues of $23.6 million. As a
result of the strong level of orders booked in the first quarter of 2001 and
backlog entering the year, revenue is likely to increase in the upcoming quarter
compared with the first quarter of 2001. The Company booked orders totaling
$28.6 million in the first quarter of 2001 compared with $25.3 million in the
same period of 2000.

Systems segment revenue was $18.8 million in the first quarter of 2001 compared
to $22.4 million during the same period in 2000. Kirk & Blum's decrease is
partially attributable to a decline in sales to the automotive industry among
other factors. Busch booked a significant order in excess of $1 million in the
first quarter of 2001 for a fume exhaust system at a substantial aluminum
rolling mill. A significant portion of the revenue from this order is expected
to be recognized during the year. Demand for the Busch unit's proprietary
JET*STAR(TM) cooling technology continued to be soft into the first quarter of
2001, and the unit continues to see decreases in demand at steel rolling mills
for fume exhaust systems.

Media segment revenue was $1.1 million for the first quarter of 2001 compared to
$1.2 million during the same period in 2000. Filters saw an increase in revenues
for the first quarter of 2001 of $0.2 million while the Company's high
performance filter media unit, Air Purator Corporation revenue declined by $0.3
million. A new marketing initiative for this segment, focusing on nurturing
relationships and increasing repeat orders from existing customers, was rolled
out in the first quarter of 2001. The Company believes that an increase in
revenue from this initiative may be realized later in the year.

Gross Profit

Gross profit was $3.6 million during the first quarter of 2001 compared with
$4.8 million in the same period in 2000. Gross profit as a percentage of
revenues was 18.0% in the first quarter of 2001 compared with 20.3% in the same
period in 2000. The decline is attributable to decreased sales by the higher
margin Media segment as well as from the lower margin Systems segment.

Expenses

Selling and administrative expenses decreased for the first quarter of 2001 by
$0.8 million to $2.6 million. Selling and administrative expenses as a
percentage of revenues for the first quarter of 2001 were 13.8%. The majority of
the decrease for the first quarter of 2001 related to cost saving initiatives
put into place in 2000, and a reversal of a contingency reserve held in
connection with a customer bankruptcy.

Depreciation and amortization increased $0.1 million to $0.6 million in the
first quarter of 2001 primarily due to the larger base of depreciable assets.

- --------------------------------------------------------------------------------


Investment Income

Investment income decreased by $0.4 million during the first quarter of 2001.
The decrease in investment income was primarily due to a decrease in unrealized
appreciation in marketable securities.

Interest Expense

Interest expense increased by $0.1 million for the first quarter of 2001
compared with the same period of 2000, principally due to higher borrowing
levels and increased rates under the bank credit facilities.

Income Taxes

Federal and state income tax benefits were $0.4 million in the first quarter of
2001. The effective income tax rate was 53% during the first quarter of 2001.
The Company's effective tax rate during 2001 is affected by non-deductible
goodwill amortization and interest expense.

Net Income

Net loss for the three months ended March 31, 2001 was $0.3 million compared
with net income of $0.1 million in the same period in 2000.

Backlog

The Company's backlog consists of purchase orders it has received from products
and services it expects to deliver within the next 12 months. The Company's
backlog, as of March 31, 2001, was approximately $21 million, an increase of $8
million over December 31, 2000. The Systems segment generated in excess of 90%
of the backlog. There can be no assurance that backlog will be replicated,
increased or translated into higher revenues in the future. The success of the
Company's business depends on a multitude of factors that are out of the
Company's control.

Financial Condition, Liquidity and Capital Resources

At March 31, 2001, the Company had total cash and cash equivalents and
marketable securities of $1.3 million compared to $1.7 million at December 31,
2000. Cash used in operating activities for the three months ended March 31,
2001 was $0.4 million compared with cash provided by operations of $0.8 million
for the same period in 2000

Bank and related debt as of March 31, 2001 was $26.5 million, an increase of
$0.1 million, primarily due to net borrowings under bank credit facilities
offset by payments made with respect to other notes payable. The bank credit
facility was amended in March 2001, as discussed in the Company's Form 10-KSB
for the year ended December 31, 2000. Unused credit availability at March 31,
2001, was $3.5 million under the Company's bank line of credit. Management and
the holders executed an amendment to the subordinated note agreements to include
a conversion feature that is exercisable by the Company.

Investing activities used cash of $0.1 million during the first three months of
2001 related to capital expenditures for property and equipment and intangibles.
Capital expenditures for property and equipment are anticipated to be in the
range of $0.7 million to $0.9 million for fiscal year 2001.

Financing activities provided $0.1 million during the first three months of 2001
compared with cash used in financing activities of $1.0 million during the same
period of 2000. Current year financing activities included net borrowings under
bank credit facilities and proceeds from common stock issued under the Company's
Employee Stock Purchase Plan.

The Company believes that its cash and cash equivalents and marketable
securities, its cash flows from operating activities, and its existing credit
facilities are adequate to meet the Company's cash requirements over the next
twelve months.
