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, 2011 and the results of operations and of cash flows for the three-month periods ended March 31, 2011 and 2010. The results of
operations for the three-month period ended March 31, 2011 are not necessarily indicative of the results to be expected for the full year. The balance sheet as of December 31, 2010 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, 2010 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, 2010 filed with the Securities and Exchange Commission.

2. New Accounting Pronouncements

Recently Issued Accounting

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 each 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 a 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 2010 annual evaluation of goodwill did not indicate an impairment of the goodwill for any of the Companys reporting units.

The fair value measurement method used in the Companys impairment analysis utilizes a number of significant unobservable inputs or Level 3 assumptions. These assumptions include, among others,
projections of our future operating results, the implied fair value of these assets using an income approach by preparing a discounted cash flow analysis and other subjective assumptions.

Amortization of finite life intangibles for the three months ended March 31, 2011 and 2010 was $126,000 and $135,000, respectively.
Over the next five years amortization expense for these finite life intangible assets will be $298,000 for the remainder of 2011, $316,000 in 2012, $130,000 in 2013, $69,000 in 2014 and $6,000 in 2015.

CECO ENVIRONMENTAL CORP.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)



For the three months ended March 31, 2011 and 2010, basic weighted average common
shares outstanding were 14,313,851 and 14,296,832, respectively, and diluted average common shares outstanding were 17,093,036 and 14,358,267, 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, 2011, there were no non-vested restricted share awards outstanding . For the three month period ended March 31, 2010, 47,308
non vested 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, 2011 and 2010, 425,000 and 1,150,000 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 after tax impact of interest related to the Investor Notes (see Note 8) unless the effect is anti-dilutive. The net after tax impact of interest related to the Note and Investor Notes for the three month periods ended
March 31, 2011 and 2010 was approximately $95,000 and $97,000, respectively. Because of a dilutive effect, net income was adjusted for this net impact for the three month period ended March 31, 2011 and 2,668,333 shares were included in
the computation of diluted weighted average common shares outstanding. Because of an anti-dilutive effect, net income was not adjusted for this impact for the three month period ended March 31, 2010 and 2,700,000 shares were excluded from the
computation of dilutive weighted average common shares outstanding for that period.

8. Debt

Our current credit facility with Fifth Third Bank (the Bank Facility), as amended, includes a revolving line of credit of up
to $20.0 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 up to $7.5 million. No amounts
were outstanding on the Bank Facility as of March 31, 2011 or December 31, 2010. Unused credit availability under our $20.0 million revolving line of credit at March 31, 2011 was $10.6 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, 2011 and March 31, 2010 was 3.0% and 3.95%, 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 August 6, 2010, the Company entered into an amended and restated credit agreement effective as of June 30, 2010, which amends
and restates in its entirety the Bank Facility and extends the termination date of the Line of Credit to April 1, 2013 and the term loan to April 1, 2014 (which was nonetheless paid off in 2010). The amendment and restatement also
increases the limit on letters of credit from $5.0 million to $10.0 million, resets the pricing grid to level one, which temporarily increased our interest rates by 0.5% until the next pricing grid determination date of December 31, 2010, at
which time the pricing level was re-determined based on the Companys trailing twelve month fixed charge ratio to be at level three, which reduced our interest rates by 0.5%. No fees were paid for this amendment.

Terms of the Bank Facility, as amended, include financial covenants that require compliance at June 30, 2010 and each quarter through
March 31, 2013. The maximum capital expenditures financial covenant is $2.5 million 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, 2011, we were 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.

Our property and equipment, accounts receivable, investments and inventory serve as
collateral for our bank debt. Our debt agreements contain customary covenants and events of default.

The bank debt at
March 31, 2011 consists of $0.1 million due on a revolving line of credit at Flextor, our Canadian subsidiary.

On
November 26, 2009, the Company issued $10.8 million principal amount unsecured convertible subordinated promissory notes to a group of investors (the Investor Notes) which includes related parties: Icarus Investment Corp.
($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. Interest paid for the three and six month periods was $162,000 and $324,000, respectively. We used the proceeds of the Investor Notes to repay all of our 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 were available to 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. The outstanding balance of the Investor Notes at March 31, 2011 and December 31, 2010 was $10.6
million and $10.8 million, respectively. In February 2011, $200,000 principal of the Investor Notes was converted to 50,000 shares of our common stock.

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 2011 totaling $58,000. We
anticipate contributing $349,000 to fund the pension plan and $21,000 for the retiree health care plan during the remainder of fiscal of 2011.

The funded status for both plans is calculated based on the projected postretirement benefit obligation.

10. Stock-Based Compensation

CECO ENVIRONMENTAL CORP.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)



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
$252,000 and $224,000 during the quarters ended March 31, 2011 and 2010, 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, 2011 and December 31, 2010, the liability for uncertain tax positions totaled approximately $86,000. The Company recognizes interest accrued related to uncertain
taxpositions 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 and postretirement liability that do not directly impact
net earnings and translation gains and losses for foreign operations. Comprehensive income of $1,432,000 included net income of $1,258,000 and a translation gain of $174,000 for the three month period ended March 31, 2011, and comprehensive
income of $204,000 for the three month period ended March 31, 2010 included net income of $97,000 and a translation gain of $107,000.

13. Product Warranties

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, 2011 and December 31, 2010, 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. Commitments and Contingencies  Legal Matters

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 (Kirk & Blum), 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 matter was submitted to
court-ordered mediation in January 2011, which was unsuccessful. It is believed that the matter will proceed to trial in the third quarter of 2011. 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. At this time, we believe that the claims are without merit and we intend to vigorously defend this suit. While there is a potential for an adverse verdict, the Company believes that
any such loss other than $25,000 would be covered by insurance. No loss is considered probable at this time.

On
January 13, 2011, the SEC initiated a non-public formal investigation relating to possible insider trading by affiliates of and/or the Company. We have been cooperating with and intend to continue to cooperate with the SEC. We have been
informed by our Chairman of the Board that he has received a subpoena in connection with such inquiry. In accordance with the terms of our bylaws and the General Corporation Law of Delaware, we are advancing expenses incurred by our Chairman in this
matter. Because the matter is ongoing, we cannot predict the outcome of this formal inquiry at this time, and, as a result, no conclusion can be reached as to what impact, if any, this inquiry may have on us or our operations.

CECO ENVIRONMENTAL CORP.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)



One of the unions, Local 24 of the Sheet Metal Workers International Association, that
represented former employees of Kirk & Blum has filed a demand to bargain under its collective bargaining agreement over the decision to close our Oakley facility and the effects of any such closing in connection with the layoffs of
approximately 40 union employees of Kirk & Blum in 2010. The union is requesting severance payments and other non-monetary items. The parties have been in negotiations and in January 2011, the grievance was heard by a panel of the National
Joint Adjustment Board for the Sheet Metal Industry, which resulted in a deadlock. The next National Adjustment Board panel hearing is expected to take place in Indianapolis, Indiana on June 21, 2011. In addition, the Sheet Metal Workers
International Association has requested information relating to the Companys facility closure decisions, the subcontracting to outside vendors of work, and related matters such as equipment transfers and union employee layoffs. If neither of
these matters is settled to the satisfaction of the parties, the unions may file charges with the National Labor Relations Board or file grievances under the applicable collective bargaining agreement. We believe this demand is without merit and
intend to vigorously defend these matters. No loss is considered probable or estimable at this time for these matters.

The
final outcome and impact of these matters, and related claims and investigations that may be brought in the future, are subject to many variables, and cannot be predicted. We establish accruals only for those matters where we determine that a loss
is probable and the amount of loss can be reasonably estimated. As a result, we have not accrued for any liability with respect to these matters. The Company expenses legal costs as they are incurred. While it is currently not possible to reasonably
estimate the aggregate amount of costs which we may incur in connection with these matters.

16. 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:

The Kirk & Blum Contracting/Services Indianapolis plant was sold in February 2011. An impairment charge of $324,000 was recorded in the fourth quarter of 2010 to reflect the loss on the pending
sale and the assets of $526,000 were classified as held for sale as of December 31, 2010.

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, 2011 and 2010 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. These products and services are marketed
under the Kirk & Blum, CECO Filters, CECOaire, Busch International, CECO Abatement Systems, kbd/Technic, K&B Duct, Effox, GMD,
Fisher Klosterman, Flextor and A.V.C. trade names. 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, steel,
ceramics, metal working, 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.

We operate in three segments: the Contracting/Services Group, which produces air pollution control and industrial ventilation
systems, the Engineered Equipment and Parts Group, which produces various types of air pollution control equipment and the Component Parts Group, which manufactures products used by us and other air pollution control companies and contractors. It is
through combining the efforts of some or all of these groups that we are able to offer complete turnkey systems to our customers and leverage the operational efficiencies between our family of companies. Due to the relative size of our Engineering
Group, our reportable segment disclosures in our financial statements include this groups results with our corporate and other disclosures.

We believe that as economic conditions continue to improve, there will be an increase in the level of pollution control capital expenditures driven by an elevated focus on environmental issues such as
global warming and energy saving alternatives as well as a U.S. Government supported effort to reduce our dependence on foreign oil through the use of bio-fuels like ethanol and electrical energy generated by our abundant domestic supply of coal. We
also feel that similar opportunities will continue to develop outside the United States.

We continue to focus on increasing revenues and
profitability. Our operating strategy has involved horizontally expanding our scope of products and services through selective acquisitions and the formation of new business units that are then vertically integrated into our growing family of
turnkey system providers. By employing this strategy, we have expanded our business and increased our revenues by adding CECO Abatement Systems, K&B Duct, CECO Filters, India, Effox, FKI, Flextor and A.V.C. At the same time, we have been able to
consolidate these new entities into our existing corporate structure without increasing costs proportionally.

Much of our business is driven
by various regulatory standards and guidelines governing air quality in and outside of factories.

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.

During 2009, the Company discontinued the operations of its subsidiary, H.M. White, Inc. We terminated our 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.

Consolidated net sales from
continuing operations for the first quarter were $36.0 million, an increase of 2.7% or $1.0 million compared to the same quarter in 2010. The increase in first quarter net sales from continuing operations was attributable to a 12.2% increase in our
Engineered Equipment and Parts Group sales and a 16.8% increase in the Component Parts Group sales offset by a 8.4% decrease in our Contracting/Services Group sales. The Engineered Equipment and Parts Group sales increased primarily due to increased
demand for our Fisher-Klosterman FCC Cyclones products and increased demand for our Effox/Flextor dampers and expansion joints. The Component Parts Group sales increase was due to continuing demand from small contractors for their products. The
Contracting/Services Group sales continue to be negatively impacted by economic conditions.

Orders booked from continuing operations in the
first quarter of 2011 were $33.3 million as compared to $27.1 million during the first quarter of 2010, an increase of $6.2 million or 23%. Bookings have primarily improved due to the recovering economy.

CECO ENVIRONMENTAL CORP.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS



First quarter 2011 gross profit from continuing operations was $8.5 million compared to gross profit
from continuing operations of $8.0 million during the same period in 2010. This $0.5 million increase in gross profit was the result of increased overall revenues. Gross profit from continuing operations, as a percentage of sales, increased to 23.6%
in the first quarter 2011 from 22.9% in the comparable prior year quarter. Engineered Equipment and Parts Group revenues before intercompany eliminations, which generate higher margins, comprised 74.8 % of our current quarterly revenues
compared to 68.5% for the same period last year. This shift in product mix is due to the greater impact of the recovering economy on the Engineered Equipment and Parts 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.

Selling and administrative expenses from
continuing operations decreased by $1.3 million to $5.9 million from $7.2 million during the first quarter of 2011 compared to the same period of 2010. Reduced wages and fringe benefits across all segments accounted for $1.2 million of this
reduction. This was primarily the result of our streamlined staffing levels.

Amortization expense, which is primarily related to acquisition
intangibles, decreased to $111,000 for the three months ended March 31, 2011 compared to $135,000 for the three months ended March 31, 2010. This decrease was due primarily to intangibles related to prior acquisitions becoming fully
amortized.

Operating income from continuing operations increased by $1.8 million to $2.4 million in the first quarter of 2011 compared to
$0.6 million during the same quarter of 2010. This increase was due to primarily to significant improvement in the operating income of our Contracting/Services Group and Component Parts Group, offset by a decrease in the operating income of our
Engineered Equipment and Parts Group. The operating income of our Engineered Equipment and Parts Group declined due primarily to one, lower margin project at our Effox/Flextor division.

Interest expense for the three months ended March 31, 2011 remained constant at $0.3 million.

Federal and state income tax expense totaled $0.8 million during the first quarter of 2011 compared to $0.1 million during the first quarter of 2010. The
estimated federal and state income tax rate in the first quarter of 2011 was 40% compared to 38% in 2010. 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, 2011 was $1.3 million compared
to net income from continuing operations of $0.2 million for the same period in 2010, and net income for the quarter ended March 31, 2011 was $1.3 million compared to net income of $0.1 million for the same period in 2010.

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, 2011, was $51.6 million compared to $54.3 million as of December 31, 2010. 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,

Financial Condition, Liquidity and Capital Resources

Our principal sources of liquidity are cash flow from operations and available borrowings under our revolving credit facility. At March 31, 2011 and December 31, 2010, cash and cash equivalents
totaled $6.7 million and $5.8 million, respectively. The current cash balance is primarily the result of net proceeds from the sale of several Contracting/ Services Group properties in the third and fourth quarters of 2010 and the first quarter of
2011. 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 at March 31, 2011 was $0.1 million and nil at December 31, 2010. The bank debt at March 31, 2011 consists of $0.1 million due on the revolving lines of credit. Our current
credit facility with Fifth Third Bank (the Bank Facility), as amended, includes a revolving line of credit of up to $20.0 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 up to $7.5 million. Unused credit availability under our $20.0 million revolving line of credit at March 31, 2011 was $10.6 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, 2011 and March 31, 2010 was 3.0% and 3.95%, 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
August 6, 2010, the Company entered into an amended and restated credit agreement effective as of June 30, 2010, which amends and restates in its entirety the Bank Facility and extends the termination date of the Line of Credit to
April 1, 2013 and the term loan to April 1, 2014 (which was nonetheless paid off in 2010). The amendment and restatement also increases the limit on letters of credit from $5.0 million to $10.0 million, resets the pricing grid to level
one, which temporarily increased our interest rates by 0.5% until the next pricing grid determination date of December 31, 2010, at which time the pricing level was re-determined based on the Companys trailing twelve month fixed charge
ratio to be at level three which reduced our interest rates by 0.5%. No fees were paid for this amendment.

Terms of the Bank Facility, as
amended, include financial covenants which require compliance at June 30, 2010 and each quarter through March 31, 2013. The maximum capital expenditures financial covenant is $2.5 million 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, 2011, we were 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.

Our property and equipment, accounts receivable, investments and inventory serve as collateral for our bank
debt. Our debt agreements contain customary covenants and events of default.

On November 26, 2009, the Company issued $10.8 million
principal amount unsecured convertible subordinated promissory notes to a group of investors (the Investor Notes) which includes related parties: Icarus Investment Corp. ($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. Interest paid for the three and six
month periods was $162,000 and $324,000, respectively. We used the proceeds of the Investor Notes to repay all of our 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 were available for use 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.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS



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. The outstanding balance of the Investor Notes at March 31, 2011 and December 31, 2010, was $10.6 million and
$10.8 million, respectively. In February 2011, $200,000 principal of the Investor Notes was converted to 50,000 shares of our common stock.

For the three months ended March 31, 2011, $0.8 million of cash was provided by continuing operating activities
compared to $2.4 million used by continuing operating activities for the same period in 2010. The $3.2 million increase in cash flows from continuing operating activities was due to an increase in net income of $1.2 million and a net $2.2 million
decrease in non-cash working capital requirements. The net decrease in working capital requirements was largely due to a $0.9 million increase in cash provided by the change in accounts receivable, primarily due to higher revenues, and an increase
in cash provided by the change in uncompleted contract balances of $0.8 million. Cash used for accounts payable decreased to $0.9 million from cash used of $2.3 million in the 2010 quarter for a net change of $1.4 million. These working capital
changes were offset by a $0.5 million use of cash in the first quarter of 2011 for a reduction in income taxes payable.

Our net investment in
working capital (excluding cash and cash equivalents, current portion of debt and working capital from discontinued operations) at March 31, 2011 was $17.0 million as compared to $16.1 million at December 31, 2010. We believe that our
working capital needs will remain constant unless we experience a significant change in sales and operating income.

For the three months
ended March 31, 2011, net cash provided by investing activities related to proceeds from the sale of our Indianapolis facility of $0.5 million offset by capital expenditures for property and equipment of $0.2 million. For the three months ended
March 31, 2010 capital expenditures for property and equipment totaled $0.2 million.

For the three months ended March 31, 2011,
financing activities included net borrowings by our Canadian subsidiary which provided cash of $0.1 million compared with cash provided of $1.9 million for borrowings from our Bank Facility during the same period of 2010. Additionally, cash of $0.4
million was used in the first quarter of 2011 to purchase the CECO shares held by a retiring executive.

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.
