CECO ENVIRONMENTAL CORP.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)



|1. | Basis of reporting for consolidated financial statements
|-- | --------------------------------------------------------

The accompanying unaudited condensed consolidated financial statements of CECO Environmental Corp. and subsidiaries (the
Company, we, us, or our) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual
financial statements have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, the accompanying unaudited, condensed consolidated financial statements of the Company contain all adjustments (consisting
only of normal recurring adjustments) necessary to present fairly the financial position as of March 31, 2010 and the results of operations and of cash flows for the three-month periods ended March 31, 2010 and 2009. The results of
operations for the three-month period ended March 31, 2010 are not necessarily indicative of the results to be expected for the full year. The balance sheet as of December 31, 2009 has been derived from the audited consolidated financial
statements included in the Companys annual report on Form 10-K for the year ended December 31, 2009 filed with the Securities and Exchange Commission.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America,
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those estimates.

During 2009, the Company discontinued
the operations of its subsidiary, H.M. White, Inc. (H.M. White). In accordance with the provisions of FASB ASC Subtopic 205-20, the results of H.M. White are presented as discontinued operations for all periods in the consolidated
financial statements. See footnote 15 for additional details.

These financial statements and accompanying notes should be read
in conjunction with the audited financial statements and the notes thereto included in the Companys Annual Report on Form 10-K for the fiscal year ended December 31, 2009 filed with the Securities and Exchange Commission.



|2. | New Accounting Pronouncements
|-- | -----------------------------

Recently Issued Accounting Pronouncements

Accounting Standards Codification (ASC) 605-25In October 2009, the Financial Accounting Standards Board
(FASB) issued Accounting Standards Update (ASU) No. 2009-13 for updated revenue recognition guidance under the provisions of ASC 605-25, Multiple-Element Arrangements. The previous guidance has been retained
for criteria to determine when delivered items in a multiple-deliverable arrangements should be considered separate units of accounting, however the updated guidance removes the previous separation criterion that objective and reliable evidence of
fair value of any undelivered items must exist for the delivered items to be considered a separate unit or separate units of accounting. This guidance is effective for fiscal years beginning on or after June 15, 2010. The Company does not
expect that the adoption of this guidance will have a material effect on the Companys consolidated results of operations, financial position or cash flows.

ASC 820In January 2010, the FASB issued ASU No. 2010-06, Fair Value Measurements and Disclosures (Topic 820):
Improving Disclosures About Fair Value Measurements. This guidance amends Subtopic 820-10 to require new disclosures and clarify existing disclosures. This guidance requires new disclosures of amounts and reasons for significant transfers
between Level 1 and Level 2 fair value measurements. Additionally, in the reconciliation for fair value measurements using significant unobservable inputs (Level 3), separate presentation of information about purchases, sales, issuances and
settlements is required. The guidance clarifies that fair value measurement disclosures for each class of assets and liabilities may constitute a subset of assets and liabilities within a line item on a reporting entitys balance sheet. The
guidance also clarifies disclosure requirements about inputs and valuation techniques for both recurring and nonrecurring fair value measurements (Level 2 or Level 3). The ASU also amends guidance on employers disclosures about postretirement
benefit plan assets under ASC 715 to require that disclosures be provided by classes of assets instead of by major categories of assets. The new disclosures and clarifications of existing disclosures are effective for interim and annual reporting
periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances and settlements in the roll forward of activity for Level 3 fair value measurements. Those disclosures are effective for fiscal years
beginning after December 15, 2010, including interim periods within those fiscal years. The Company has not had and does not expect that the adoption of this remaining guidance will have a material effect on the Companys consolidated
results of operations, financial position or cash flows.

(unaudited)

ASC 815In March 2010, the FASB issued ASU 2010-11, Scope Exception Related to Embedded Credit Derivatives to
address questions that have been raised in practice about the intended breadth of the embedded credit derivative scope exception in paragraphs 815-15-15-8 through 815-15-15-9 of ASC 815, Derivatives and Hedging. The amended guidance
clarifies that the scope exception applies to contracts that contain an embedded credit derivative that is only in the form of subordination of one financial instrument to another. This guidance is effective on July 1, 2010 for the Company. The
adoption of this guidance is not expected to have a material impact on the Companys consolidated financial position, results of operations or cash flows.

Revenues from contracts, representing the majority of our revenues, are recognized on the percentage of
completion method, measured by the percentage of contract costs incurred to date compared to estimated total contract costs for each contract. This method is used because management considers contract costs to be the best available measure of
progress on these contracts.

Our remaining revenues are recognized when risk and title passes to the customer, which is
generally upon shipment of product. Our contracts have various lengths to completion ranging from a few days to several months. We anticipate that a majority of our current contracts will be completed by year end.

We complete an annual (or more often if circumstances
require) impairment test for our indefinite life intangible assets. In performing these assessments, the carrying value of the asset is considered impaired if the fair value is less than the carrying value of the asset. If this occurs, an impairment
charge is recorded for the amount by which the carrying value of the asset exceeds its fair value.

Also as required by current
accounting rules, we complete an annual (or more often if circumstances require) impairment test for our goodwill. In performing these assessments, the carrying value of the reporting unit is compared to its estimated fair value, as calculated by
the discounted present value of cash flow method. If the estimated fair value of the reporting unit is less than its carrying value, an impairment charge is recorded for the amount by which the carrying value of the goodwill exceeds its calculated
implied fair value. The Companys fourth quarter 2009 annual evaluation for goodwill impairment indicated an impairment of the goodwill for four of the Companys reporting units. As a result, the Company estimated the implied fair value of
the goodwill of these reporting units compared to carrying amounts and recorded total impairment charges of $17.1 million at December 31, 2009 to impair a portion of the goodwill recorded on these reporting units. The decrease in the fair value
of the reporting units was due to deteriorating market conditions resulting from the global economic downturn. No impairment of goodwill was identified related to the Companys other reporting units. No additional impairment was recorded in the
first quarter of 2010.

Major factors that influence our cash flow analyses are our estimates for future revenue and expenses
associated with the reporting units. This is the most sensitive of our estimates related to our fair value calculations. Other factors considered in our fair value calculations include assumptions as to the business climate, industry and economic
conditions. These assumptions are subjective and different estimates could have a significant impact on the results of our analyses.

Finite life intangible assets are comprised of patents, backlog, customer lists and employment contracts. For all amortizable intangible
assets, if any events or changes in circumstances occur that indicate possible impairment, our impairment review is based on an undiscounted cash flow analysis. Impairment occurs when the carrying value of the assets exceeds the future undiscounted
cash flows. When impairment is indicated, the estimated future cash flows are then discounted to determine the estimated fair value of the asset and an impairment charge is recorded for the difference between the carrying value and the net present
value of estimated future cash flows. The Company also evaluates the remaining useful life each reporting period to determine whether events and circumstances warrant a revision to the remaining period of amortization. If the estimate of an
intangible assets remaining useful life is changed, the remaining carrying amount of the intangible asset is amortized prospectively over that revised remaining useful life.

Amortization of finite life intangibles is on a straight line basis and amortization
expense for the three months ended March 31, 2010 and 2009 was $135,000 and $313,000, respectively. Over the next five years amortization expense is $494,000 for all of 2010, $424,000 in 2011, $316,000 in 2012, $130,000 in 2013 and $69,000 in
2014.



|6. | Business Segment Information
|-- | ----------------------------

Our structure and operational integration results in one reportable segment that focuses on engineering, designing, building and
installing systems that remove airborne contaminants from industrial facilities, as well as equipment that controls emissions from such facilities. Accordingly, the consolidated financial statements herein reflect the operating results of the
reportable segment.



|7. | Earnings Per Share
|-- | ------------------

For
the three months ended March 31, 2010 and 2009, basic weighted average common shares outstanding were 14,296,832 and 14,322,777, respectively, and diluted average common shares outstanding were 14,358,267 and 15,189,775, respectively.

Effective January 1, 2009, the Company adopted ASC 260-10-65-2, Determining Whether Instruments Granted in
Share-Based Payment Transactions are Participating Securities. Non-vested shares with non-forfeitable dividend rights are considered participating securities and, thus, subject to the two-class method pursuant to ASC Topic 260, Earnings
per Share, when computing basic and diluted EPS. Losses are only allocable to participating securities if the holder has a contractual obligation to share in the losses of the Company.

Holders of our restricted stock awards participate in nonforfeitable dividend rights on a one-for-one basis with holders of common stock.
Holders of these awards are not obligated to share in losses of the Company. Therefore, these share awards are included in the computation of basic earnings (loss) per share during periods of net income using the two-class method, but are excluded
from such computation in periods of net loss. Should the Company declare a dividend on its common stock, the related dividend on shares of unvested restricted stock that are not expected to vest would be recorded as additional compensation expense
and therefore excluded from the two-class method computations; however, no such dividends have been declared to date. Undistributed earnings included in the two-class method computations are allocated equally to each share of common stock
outstanding, including all shares of unvested restricted common shares. For the three month period ended March 31, 2010, the weighted average number of non-vested restricted share awards which were included in the basic weighted average common
shares outstanding totaled 47,308. For the three month period ended March 31, 2009, 127,128 restricted share awards were included in the computation of basic weighted average common shares outstanding.

We consider outstanding options and warrants in computing diluted net income per share only when they are dilutive. For the three month
periods ended March 31, 2010 and 2009, 1,150,000 and 1,098,000 outstanding options and warrants were excluded from the computation of diluted weighted average common shares outstanding as their effect would have been anti-dilutive.
Additionally, pursuant to the if-converted method, net income used for purposes of computing diluted earnings per share is adjusted for the net impact of interest and other items related to the Convertible Subdebt Note and Investor Notes (see Note
8) unless the effect is anti-dilutive. The net impact of interest and other items related to the Convertible Subdebt Note and Investor Notes for the three month periods ended March 31, 2010 and 2009 was approximately $97,000 and $27,000,
respectively. Because of an anti-dilutive effect, net income was not adjusted for this net impact for the three month period ended March 31, 2010 and 2,700,000 shares were excluded from the computation of diluted weighted average common shares
outstanding.



|8. | Debt
|-- | ----

Total bank debt at
March 31, 2010 was $4.4 million and $2.7 million at December 31, 2009. The bank debt at March 31, 2010 consists of $2.3 million due on the revolving lines of credit and a term note totaling $2.1 million. `Our current credit facility
with Fifth Third Bank (the Bank Facility), as amended, includes a revolving line of credit of up to $20 million, including letters of credit, limited to a borrowing base amount computed as 70% of eligible accounts receivable, 50% of
unbilled revenues up to $1.0 million, plus 50% of eligible inventories. Unused credit availability under our $20.0 million revolving line of credit at March 31, 2010 was $7.1 million. Interest on the outstanding borrowings is charged at the
daily LIBOR rate plus 3.5% or the tranche LIBOR rate plus 3.0% for the revolver and the daily LIBOR rate plus 3.75% or the tranche LIBOR rate plus 3.25% for the term note. The weighted average interest rate under the Bank Facility as of
March 31, 2010 and March 31, 2009 was 3.95% and 2.74%, respectively.

We entered into our current Bank Facility on
December 29, 2005 with Fifth Third Bank. The Bank Facility was amended on various dates and fees paid for these amendments were deferred and are being amortized over the remaining term of the Bank Facility.

On May 1, 2009, the Company entered into a Sixth Amendment to the Bank Facility effective as of March 31, 2009. The Sixth
Amendment amends the Bank Facility to extend the termination date of the line of credit from January 31, 2010 to April 1, 2011, make certain changes to the interest rates applicable to the obligations under the Bank Facility, including the
implementation of a daily reset, one-month LIBOR-based rate and the unavailability of a prime-based rate except in certain circumstances, which results in an increase of the borrowing rates by one percent, consent to a one-time payment of principal
on the Subordinated Convertible Promissory Note of Icarus Investment Corp. (Icarus) in an amount not to exceed $3.0 million, and consent to an extension fee of CAD $38,000 payable to Icarus.

On August 17, 2009, the Company entered into a Seventh Amendment to Credit
Agreement to the Bank Facility, effective as of May 15, 2009. The Seventh Amendment incorporates the Note (as described below) as permitted subordinated debt, and permits prepayments under the Note so long as the Company is not in default under
the Bank Facility.

On November 26, 2009, the Company entered into an Eighth Amendment to Credit Agreement to the Bank
Facility effective as of November 26, 2009. The Eighth Amendment permitted the Company to issue subordinated loans, in an aggregate amount not to exceed $11.4 million, to subordinated creditors and permitted the payment in full by the Company
of the subordinated debt of Icarus outstanding on the effective date, in an aggregate amount equal to $4.5 million.

On
February 12, 2010, the Company entered into a Ninth Amendment to Credit Agreement to the Bank Facility effective as of December 31, 2009. The Ninth Amendment decreased the maximum loan commitment from $30.0 million to $20.0 million,
decreased the monthly required term loan payment from $83,333 to $26,886, increased the minimum fixed charge coverage ratio financial covenant from 1.25 : 1.0 to 2.5 : 1.0, and permitted the addition of $6.3 million of net funding received from the
private placement of subordinated debt to the adjusted EBITDA calculation used in the financial covenants.

Terms of the Bank
Facility, as amended, include financial covenants which require compliance at December 31, 2009 and each quarter through March 31, 2011. The maximum capital expenditures financial covenant is $2,500,000 per year. The minimum Fixed Charge
Coverage Ratio is 2.5 : 1.0 for each quarter through the quarter ended June 30, 2010 and 1.25 : 1.0 thereafter. The maximum funded debt to EBITDA covenant is 3.0 to 1. Our Bank Facility also contains cross-default provisions with respect to our
subordinated debt. Also, if we fail to pay (after grace periods) any other debt or lease that, individually or in the aggregate involves indebtedness in excess of $100,000, and such default gives any creditor or lessor the right to accelerate the
maturity of any such indebtedness or lease payments, then absent a waiver from the lender, it would result in a default under our Bank

Facility and the acceleration of the maturity of outstanding debt under our Bank Facility. As of March 31, 2010, we were well in
compliance with all related financial and other restrictive covenants, and expect continued compliance.

On August 14,
2008, the Company issued a Subordinated Convertible Promissory Note (the Convertible Subdebt Note) in the amount of Canadian $5.0 million to Icarus, which is controlled by Phillip DeZwirek, our Chairman and former CEO, and Jason
DeZwirek, our Secretary and one of our Directors. The Convertible Subdebt Note provided for interest to accrue at the rate of 10% per annum in 2008, 11% per annum in 2009, and 12% per annum commencing January 1, 2010 until paid.
The outstanding principal and accrued interest under The Convertible Subdebt Note was convertible at any time into common stock of the Company at a per share price of $4.75 which was the closing price immediately preceding the issuance of the
Subdebt. The Convertible Subdebt Note was amended in February 2009 to provide for interest payments to be payable monthly, instead of semi-annually, subject to the Subordination Agreement between Fifth Third Bank and Icarus. The Convertible Subdebt
Note was further amended on May 1, 2009 to extend its maturity date to October 1, 2011 from July 31, 2010. Fees of Canadian $38,000 were paid for this amendment and were being deferred and amortized over the remaining term of the
Convertible Subdebt Note. We repaid Canadian $3.7 million under the Convertible Subdebt Note on March 31, 2009 and fully repaid the outstanding balance of $1.2 million on November 26, 2009.

On May 15, 2009, the Company issued a Promissory Note (Note) to Icarus in the amount of $3.0 million. The Note, which was
subordinated to the Companys Bank Facility, bore interest at 12% per annum with interest payable monthly. The maturity date of the note was the earlier of May 15, 2012 or six months after repayment of the Bank Facility. At the option
of Icarus, the note was repayable in Canadian funds with a stated conversion rate of 1.1789, or CAD $3.5 million, representing the conversion rate at the issuance date of the Note. In accordance with ASC 815 Derivatives and Hedging, this
option was been bifurcated and recorded at fair value. Gains and losses resulting from the revaluation of this liability were included in other income (expense) in the consolidated statements of operations. The Note and accrued interest was fully
repaid on November 26, 2009 in the amount of $3.3 million.

On November 26, 2009, the Company issued $10.8 million
principal amount subordinated convertible promissory notes to a group of investors (the Investor Notes) which includes related parties: Icarus ($2,200,000), Jason DeZwirek ($800,000), and Harvey Sandler Revocable Trust ($800,000), which
trust owns over 10% of our outstanding common stock.

Interest accrues under the Investor Notes at the annual rate of 6% and is
payable as of the end of each calendar quarter. The Company used the proceeds of the Investor Notes to repay all of its previously existing subordinated debt in the amount of approximately $4.5 million, which debt was accruing interest at rates
between 11-12%. The balance of the proceeds will be used for general working capital. Fees of $320,000 were paid for the issuance of this debt and are being amortized over the term of the Investor Notes.

The Investor Notes are due on November 26, 2014 and are not repayable prior to
maturity except upon a change of control, or upon the consent of the holder. The outstanding principal amount of the Investor Notes or any portion thereof, but not the interest, is convertible at the holders option, at any time after the
issuance of the Investor Notes at a conversion price of $4.00 per share, such price being greater than the Companys share price at the date of issuance of the Investor Notes. Following three years from the date of the Investor Notes, if the
closing price of the common stock of the Company is greater than $8.00 for five consecutive days, the Company can cause conversion of the Investor Notes.



|9. | Pension and Employee Benefit Plans
|-- | ----------------------------------

We sponsor a non-contributory defined benefit pension plan for certain union employees. The plan is funded in accordance with the funding
requirements of the Employee Retirement Income Security Act of 1974.

We also sponsor a postretirement health care plan for
office employees retiring before January 1, 1990. The plan allows retirees who have attained the age of 65 to elect the type of coverage desired.

Retirement and health care plan expense is based on valuations performed by plan actuaries as of the beginning of each fiscal year. The
components of the expense consisted of the following:

We made contributions to our defined benefit plans in the first quarter of 2010 totaling $53,000. We
anticipate contributing $214,000 to fund the pension plan and $39,000 for the retiree health care plan during the remainder of fiscal of 2010.

The funded status for our postretirement health care plan is calculated based on the projected postretirement benefit obligation.



|10. | Stock-Based Compensation
|--- | ------------------------

The Company accounts for stock-based compensation in accordance with ASC Topic 718, Compensation  Stock Compensation
which requires the Company to recognize compensation expense for stock-based awards, measured at the fair value of the awards at the grant date. The Company recognized expense of approximately $224,000 and $234,000 during the quarters ended
March 31, 2010 and 2009, respectively.



|11. | Income Taxes
|--- | ------------

The Company
files income tax returns in various federal, state and local jurisdictions. The Company is no longer subject to federal, state and local income tax examinations by tax authorities for years before 2006.

The Company accounts for uncertain tax positions pursuant to ASC Topic 740, Income Taxes.. As of March 31, 2010 and
December 31, 2009, the liability for unrecognized tax expense totaled approximately $387,000. Included in this balance is a $148,000 tax position for which the ultimate outcome is highly certain. The Company recognizes interest accrued related
to unrecognized tax expenses in interest expense and penalties in income tax expense.



|12. | Comprehensive Income (Loss)
|--- | ---------------------------

Comprehensive income (loss) consists of net income (loss), changes in the pension liability that do not directly impact net earnings and
translation gains and losses for foreign operations. Comprehensive income of $204,000 included net income of $97,000 and a translation gain of $107,000 for the three month period ended March 31, 2010, and comprehensive income of $222,000 for
the three month period ended March 31, 2009 included net income of $369,000 and a translation loss of $(147,000).

The
Companys warranty reserve is to cover the products sold and is principally at our Effox subsidiary. The warranty accrual is based on historical claims information. The warranty reserve is reviewed and adjusted as necessary on a quarterly
basis. Warranty accrual is not significant at the Companys other operations due to the nature of the work which includes installation and testing. The change in accrued warranty expense is summarized in the following table:

|14. | Financial Instruments
|--- | ---------------------

Our financial instruments consist primarily of investments in cash and cash equivalents, receivables and certain other assets and accounts
payable. The carrying values of these financial instruments approximate fair value at March 31, 2010 and December 31, 2009, due to their short-term nature.

Most of the debt obligations approximate their reported carrying amounts based on future payments discounted at current interest rates for
similar obligations or interest rates which fluctuate with the market.



|15. | Discontinued Operations
|--- | -----------------------

During 2009, the Company discontinued the operations of H.M. White. The Company terminated its facility lease in Detroit, Michigan and all
property and equipment held by H.M. White was sold at net book value to its former owner. Accordingly, there was no gain or loss associated with the sale of H.M. Whites assets.

The results of H.M. White are presented as discontinued operations for all periods in the consolidated financial statements. The Company
did not allocate general corporate interest expense to H.M. White.

Operating results of discontinued operations are as
follows:

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)



|16. | Legal proceedings
|--- | -----------------

A
lawsuit was filed on September 10, 2009 in Marion County Superior Court, State of Indiana. A wrongful death claim has been made by the estate of Terry David Walk for an accident that occurred in March 2008 at the worksite of a customer of
the Company relating to a baghouse system. The defendants include CECO and its subsidiaries, The Kirk & Blum Manufacturing Company, kbd/Technic, Inc., and CECO Abatement Systems, Inc. The complaint contains causes of action for
negligence and a cause of action for breach of implied warranties, and the complainant is asking for unspecified compensatory damages and costs. The Companys insurance carriers have agreed to defend the claims, pursuant to
reservation of rights letters, and have retained counsel to defend the Company. We record provisions in the consolidated financial statements for pending litigation when we determine that an unfavorable outcome is probable and the amount of the loss
can be reasonably estimated. However, at this time the Company cannot estimate any potential final range of loss resulting from this litigation as it is still in discovery and accordingly, we have not provided any amounts in the consolidated
financial statements for unfavorable outcomes, if any. At this time, we believe that the claims are without merit and we intend to vigorously defend this suit.

There are no other material pending legal proceedings to which the Company or any of our subsidiaries is a party or to which any of our
properties is subject.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

ITEM 2. Managements Discussion and Analysis of Financial Condition and Results of Operations

The Companys
consolidated statements of operations for the three-month periods ended March 31, 2010 and 2009 reflect the operations of the Company consolidated with the operations of its subsidiaries.

We are one of the leading providers of air-pollution control products and services. Our revenues are generated by our services of engineering and
designing as well as building equipment, and installing systems that capture, clean and destroy airborne contaminants from industrial facilities and equipment that controls emissions from such facilities. We have a diversified base of more than
3,000 active customers among a myriad of industries including aerospace, brick, cement, ceramics, metalworking, ethanol, printing, paper, food, foundry, power, refining, mining, metal plating, woodworking, chemicals, tobacco, glass, automotive, and
pharmaceuticals. Therefore, our business is not concentrated in a single industry or customer.

On February 15, 2010, we appointed
Jeffrey Lang as our new Chief Executive Officer. Mr. Lang has more than thirty years of executive operating management experience including Executive Vice President, Chief Operating Officer at McJunkin Red Man Corp. and twenty five years at
Ingersol Rand including leading their Industrial Air Solutions sales, service and operations for North America.

Management has been closely
monitoring the current economic conditions especially as some of our customers have announced that they are facing financial distress which may adversely affect our revenues and accounts receivable. In a weak economy customers tend to lengthen the
time between inquiry and order or may defer purchasing our products and services until the economy recovers.

In light of this
reduction in demand and the new management expertise of Jeff Lang, we have focused on reducing costs throughout the company, including plant rationalizations and reductions in overhead and general and administrative expenses.

Operations Overview

Our contracts are
obtained either through competitive bidding or as a result of negotiations with our customers. Contract terms offered by us are generally dependent on the complexity and risk of the project as well as the resources that will be required to complete
the project. For example, a contract that can be performed primarily by subcontractors and that does not require us to use our fabrication and assembly facilities can be quoted at a lower gross margin than a more typical contract that will require
additional factory overhead and administrative expenses. Our focus is on increasing our operating margins as well as our gross margin percentage which translates into higher net income.

How We Manage our Business

We operate
under a hub and spoke business model in which executive management, finance, administrative and marketing staff serves as the hub while the sales channels serve as spokes. We use this model throughout our operations. This has provided us
with certain efficiencies over a more decentralized model.

Although we discuss four principal product lines, our operating units function as
internal customers and suppliers of each others products and services and as such, products and services are intermingled in one major project. As a result, it is not reasonably possible to segregate revenues to external customers, operating
profits or identifiable assets by product line.

During 2009, the Company discontinued the operations of its subsidiary, H.M. White, Inc. The
Company terminated its facility lease in Detroit, Michigan and all property and equipment held by H.M. White was sold at net book value to its former owner.

The results of H.M. White are presented as discontinued operations for the periods presented.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS



Consolidated net sales from continuing operations for the first quarter were $35.0 million, a decrease
of 8.1% or $3.1 million compared to the same quarter in 2009. The decline in first quarter net sales from continuing operations was attributable to a 40% decline in our contracting group sales offset by a 24% increase in our parts group sales and a
modest increase in equipment group sales. Parts group sales increased due to smaller contractors cutting back on shop expenses and outsourcing the component parts and ducting products that they previously made in-house. Contracting group sales
continue to be negatively impacted by the slow economy.

Orders booked from continuing operations in the first quarter of 2010 were $27.1
million as compared to $35.0 million during the first quarter of 2009, a decrease of $7.9 million or 22.6%. Bookings have also been impacted by the slowing economy.

First quarter 2010 gross profit from continuing operations was $8.0 million compared to gross profit from continuing operations of $8.7 million during
the same period in 2009. This $0.7 million decrease in gross profit was the result of lower overall revenues. Gross profit from continuing operations, as a percentage of sales, increased to 22.9% in the first quarter 2010 from 22.8% in the
comparable prior year quarter. Equipment group revenues before intercompany eliminations, which generate higher margins, comprised 64% of our current quarterly revenues compared to 55% for the same period last year. This shift in product mix is due
to the greater impact of the weak economy on the contracting/services group. Additionally, the first quarter of 2010 was negatively affected by lower margins in our contracting group due to the impact of significant costs incurred on a large project
which may continue in subsequent quarters.

Selling and administrative expenses from continuing operations remained constant at $7.2 million
during the first quarter of 2010 compared to the same period of 2009. Selling and administrative expenses in 2010 included expense items of accrued severance pay of $127,000, executive recruiting fees of $150,000 and $100,000 for bad debt expense.
These expenses were primarily offset by reductions in wages and fringes from continuing operations of $119,000 from recent staff reductions and reduced travel expenses of $64,000. We continue to streamline staffing levels and various selling and
administrative costs throughout the Company in response to the slow economy and will continue to monitor these costs as we move forward.

Amortization expense, which is primarily related to acquisition intangibles, decreased to $135,000 for the three months ended March 31, 2010
compared to $313,000 for the three months ended March 31, 2009. This decrease was due primarily to intangibles related to 2007 and 2008 acquisitions becoming fully amortized.

Operating income from continuing operations decreased by $0.6 million to $0.6 million in the first quarter of 2010 compared to $1.2 million during the
same quarter of 2009. This decrease was due to the factors previously mentioned.

Interest expense for the three months ended March 31,
2010 decreased by $69,000 to $293,000 from $362,000 during the first quarter of 2009. This decrease was due to lower rates on convertible debt and lower outstanding balances on our credit line.

Federal and state income tax expense totaled $103,000 during the first quarter of 2010 compared to $317,000 during the first quarter of 2009. The
estimated federal and state income tax rate in the first quarter of 2010 was 38% compared to 35% in 2009. Our effective income tax rate is affected by certain permanent differences including foreign income, expenses for stock based compensation and
domestic manufacturing deductions.

Net income from continuing operations for the quarter ended March 31, 2010 was $167,000 compared to a
net income from continuing operations of $587,000 for the same period in 2009 and net income for the quarter ended March 31, 2010 was $97,000 compared to net income of $369,000 for the same period in 2009.

Backlog

Our backlog consists of the
amount of revenue we expect from complete performance of uncompleted, signed, firm fixed price contracts that have not been completed for products and services we expect to substantially deliver within the next 12 months. Our backlog from continuing
operations, as of March 31, 2010, was $58.6 million compared to $66.5 million as of December 31, 2009. There can be no assurances that backlog will be replicated, increased or translated into higher revenues in the future. The success of
our business depends on a multitude of factors related to our backlog and the orders secured during the subsequent period(s). Certain contracts are highly dependent on the work of contractors and other subcontractors participating in a project, over
which we have no or limited control, and their performance on such project could have an adverse effect on the profitability of our contracts. Delays resulting from these contractors and subcontractors, changes in the scope of the project, weather,

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS



Financial Condition, Liquidity and Capital Resources

Our principal sources of liquidity are cash flow from operations, available borrowings under our revolving credit facility and convertible subordinated
debt. At March 31, 2010 and December 31, 2009, cash and cash equivalents totaled $0.9 million and $1.4 million, respectively. Generally, we do not carry significant cash and cash equivalent balances because excess amounts are used to pay
down our revolving line of credit or other indebtedness.

Total bank debt was $4.4 million at March 31, 2010 and $2.7 million at
December 31, 2009. The bank debt at March 31, 2010 consists of $2.3 million due on the revolving lines of credit and a term note totaling $2.1 million. Availability is limited as determined by a borrowing base formula contained in the
credit agreement. The Bank Facility, as amended, includes a revolving line of credit of up to $20 million, including letters of credit, limited to a borrowing base amount computed as 70% of eligible accounts receivable, 50% of unbilled revenues up
to $1.0 million plus 50% of eligible inventories. Unused credit availability under our $20.0 million revolving line of credit at March 31, 2010 was $7.1 million. Interest on the outstanding borrowings is charged at the daily LIBOR rate plus
3.5% or the tranche LIBOR rate plus 3.0% for the revolver and the daily LIBOR rate plus 3.75% or the tranche LIBOR rate plus 3.25% for the term note. The weighted average interest rate under the Bank Facility as of March 31, 2010 and
March 31, 2009 was 3.95% and 2.74%, respectively.

We entered into our Bank Facility on December 29, 2005 with Fifth Third Bank. The Bank Facility was amended on various
dates and fees paid for these amendments were deferred and are being amortized over the remaining term of the Bank Facility.

On May 1,
2009, the Company entered into a Sixth Amendment to the Bank Facility effective as of March 31, 2009. The Sixth Amendment amends the Bank Facility to extend the termination date of the line of credit from January 31, 2010 to April 1,
2011, make certain changes to the interest rates applicable to the obligations under the Bank Facility, including the implementation of a daily reset, one-month LIBOR-based rate and the unavailability of a prime-based rate except in certain
circumstances, which results in an increase of the borrowing rates by one percent, consent to a one-time payment of principal on the Subordinated Convertible Promissory Note of Icarus in an amount not to exceed $3.0 million, and consent to an
extension fee of CAD $38,000 payable to Icarus.

On August 17, 2009, the Company entered into a Seventh Amendment to Credit Agreement to
the Bank Facility, effective as of May 15, 2009. The Seventh Amendment incorporates the Note (as described below) as permitted subordinated debt, and permits prepayments under the Note so long as the Company is not in default under the Bank
Facility.

On November 26, 2009, the Company entered into an Eighth Amendment to Credit Agreement to the Bank Facility effective as of
November 26, 2009. The Eighth Amendment permitted the Company to issue subordinated loans, in an aggregate amount not to exceed $11.4 million, to subordinated creditors and permitted the payment in full by the Company of the subordinated debt
outstanding on the effective date to Icarus, in an aggregate amount equal to $4.5 million.

On February 12, 2010, the Company entered
into a Ninth Amendment to Credit Agreement to the Bank Facility effective as of December 31, 2009. The Ninth Amendment decreased the maximum loan commitment from $30.0 million to $20.0 million, decreased the monthly required term loan payment
from $83,333 to $26,886 increased the minimum fixed charge coverage ratio financial covenant from 1.25 : 1.0 to 2.5 : 1.0, and permitted the addition of $6.3 million of net funding received from the private placement of subordinated debt to the
adjusted EBITDA calculation used in the financial covenants.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS



Terms of the Bank Facility, as amended, include financial covenants which require compliance at
December 31, 2009 and each quarter through March 31, 2011. The maximum capital expenditures financial covenant is $2,500,000 per year. The minimum Fixed Charge Coverage Ratio is 2.5 : 1.0 for each quarter through the quarter ended
June 30, 2010 and 1.25 : 1.0 thereafter. The maximum funded debt to EBITDA covenant is 3.0 to 1. Our Bank Facility also contains cross-default provisions with respect to our subordinated debt. Also, if we fail to pay (after grace periods) any
other debt or lease that, individually or in the aggregate involves indebtedness in excess of $100,000, and such default gives any creditor or lessor the right to accelerate the maturity of any such indebtedness or lease payments, then absent a
waiver from the lender, it would result in a default under our Bank Facility and the acceleration of the maturity of outstanding debt under our Bank Facility. As of March 31, 2010, we were well in compliance with all related financial and other
restrictive covenants, and expect continued compliance. In the future, if we cannot comply with the terms of the Bank Facility covenants it will be necessary for us to obtain a waiver or renegotiate our loan covenants, and there can be no assurance
that such negotiations would be successful. In the event that we are not successful in obtaining a waiver or an amendment, we would be declared in default, which could cause all amounts owed to be immediately due and payable.

On August 14, 2008, the Company issued a Subordinated Convertible Promissory Note (the Convertible Subdebt Note) in the amount of
Canadian $5.0 million to Icarus, which is controlled by Phillip DeZwirek, our Chairman and former CEO, and Jason DeZwirek, our Secretary and one of our Directors. The Convertible Subdebt Note provided for interest to accrue at the rate of
10% per annum in 2008, 11% per annum in 2009, and 12% per annum commencing January 1, 2010 until paid. The outstanding principal and accrued interest under The Convertible Subdebt Note was convertible at any time into common
stock of the Company at a per share price of $4.75, which was the closing price immediately preceding the issuance of the Subdebt. The Convertible Subdebt Note was amended in February 2009 to provide for interest payments to be payable monthly,
instead of semi-annually, subject to the Subordination Agreement between Fifth Third Bank and Icarus. The Convertible Subdebt Note was further amended on May 1, 2009 to extend its maturity date to October 1, 2011 from July 31, 2010.
Fees of Canadian $38,000 were paid for this amendment and were being deferred and amortized over the remaining term of the Convertible Subdebt Note. We repaid Canadian $3.7 million under the Convertible Subdebt Note on March 31, 2009 and fully
repaid the outstanding balance of $1.2 million on November 26, 2009.

On May 15, 2009, the Company issued a Promissory Note
(Note) to Icarus in the amount of $3.0 million. The Note, which was subordinated to the Companys Bank Facility, bore interest at 12% per annum with interest payable monthly. The maturity date of the note was the earlier of
May 15, 2012 or six months after repayment of the Bank Facility. At the option of Icarus, the note was repayable in Canadian funds with a stated conversion rate of 1.1789, or CAD $3.5 million, representing the conversion rate at the issuance
date of the Note. In accordance with ASC 815 Derivatives and Hedging, this option has been bifurcated and recorded at fair value. Gains and losses resulting from the revaluation of this liability were included in other income (expense)
in the consolidated statements of operations. The Note and accrued interest was fully repaid on November 26, 2009 in the amount of $3.3 million.

On November 26, 2009, the Company issued $10.8 million principal amount subordinated convertible promissory notes to a group of investors (the
Investor Notes) which includes related parties: Icarus ($2,200,000), Jason DeZwirek ($800,000), and Harvey Sandler Revocable Trust ($800,000), which trust owns over 10% of our outstanding common stock.

Interest accrues under the Investor Notes at the annual rate of 6% and is payable as of the end of each calendar quarter. The Company used the proceeds
of the Investor Notes to repay all of its previously existing subordinated debt in the amount of approximately $4.5 million, which debt was accruing interest at rates between 11-12%. The balance of the proceeds will be used for general working
capital. Fees of $320,000 were paid for this private placement and are being amortized over the remaining term of the Investor Notes.

The
Investor Notes are due on November 26, 2014 and are not repayable prior to maturity except upon a change of control, or upon the consent of the holder. The outstanding principal amount of the Investor Notes or any portion thereof, but not the
interest, is convertible at the holders option, at any time after the issuance of the Investor Notes at a conversion price of $4.00 per share, such price being greater than the Companys share price at the date of the Investor Note
agreement. Following three years from the date of the notes, if the closing price of the common stock of the Company is greater than $8.00 for five consecutive days, the Company can cause conversion of the Investor Notes.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS



For the three months ended March 31, 2010, $2.4 million of cash was used by continuing operating
activities compared to $6.8 million provided by continuing operating activities for the same period in 2009. The $9.2 million change in cash flows from operating activities was primarily due to a net $8.6 million increase in non-cash working capital
requirements. That net increase was largely due to a $10.2 million decrease in cash provided by the change in accounts receivable in the 2010 quarter as compared to the 2009 quarter, primarily due to lower revenues. Additionally, the 2010 first
quarter change in uncompleted contract balances reflects a use of $2.2 million of cash while the 2009 first quarter change reflects a provision of $2.1 million of cash primarily due to lower advance billings to customers. These working capital
changes were offset by a $1.8 million use of cash in the first quarter of 2009 to pay income taxes that was not repeated in the first quarter of 2010. The changes in working capital elements were mainly the result of the continuing slow economic
activity.

Depreciation and amortization amounted to $0.4 million in for the three months ended March 31, 2010 compared to $0.7 million
for depreciation and amortization in the same period in 2009. This decrease in depreciation and amortization was due primarily to decreased amortization of definite life intangibles from recent acquisitions which are now fully amortized. 2010. Our
net investment in working capital (excluding cash and cash equivalents, current portion of debt and working capital from discontinued operations) at March 31, 2010 was $17.2 million as compared to $14.5 million at December 31, 2009. We
believe that our working capital needs will remain constant unless we experience a significant increase or decrease in sales and operating income.

For the three months ended March 31, 2010, net cash used in investing activities related to capital expenditures for property and equipment were
$0.2 million compared with $0.5 million for the same period in 2009. We are managing our capital expenditures in light of the current level of sales.

For the three months ended March 31, 2010, financing activities, which simply consisted of net borrowings from our bank, provided cash of $1.4
million, compared with cash used of $8.1 million during the same period of 2009 primarily related to net payment of debt.

When we undertake
large jobs, our working capital objective is to make these projects self-funding. We try to achieve this by obtaining initial down payments, progress billing contracts, when possible, utilizing extended payment terms from material suppliers, and
paying sub-contractors after payment from our customers, which is an industry practice. Our investment in net working capital is funded by cash flow from operations and by our revolving line of credit. Inventory remains relatively constant from
quarter to quarter. Accordingly, changes in inventory do not constitute a significant part of our investment in working capital.

Based on our
historical results, managements experience, our current business strategy and current cash flows, we believe that our existing cash resources will be sufficient to meet our anticipated working capital and capital expenditure requirements for
at least the next 12 months. Nevertheless, if we generate insufficient cash flows from operations or are unable to draw the amounts needed from our Bank Facility to meet our short-term liquidity needs, we may borrow additional funds. Although
management believes that we will be able to fund our operations from current resources, there is no guarantee that we will be able to do so, however, alternative sources of funding are potentially available in the form of additional term debt to be
provided by our lender, which may be collateralized by our real estate and equipment, as well as subordinated debt to be provided by a related party. However, we cannot provide any assurances that such financing will be available to us on favorable
terms or at all.

We caution investors that other factors might, in the future, prove to be important in affecting our
results of operations. New factors emerge from time to time and it is not possible for management to predict all such factors, nor can it assess the impact of each such factor on the business or the extent to which any factor, or a combination of
