CERTAIN TRANSACTIONS Since January 1, 1999, the following transactions have occurred in which persons who, at the time of such transactions, were directors, officers or owners of more than 5% of CECO's common stock, had a direct or indirect material interest. Steven Taub's employment with Filters was terminated as of June 30, 2000 pursuant to a Separation Agreement and General Release (the "Agreement"). CECO, pursuant to the Agreement, purchased on July 5, 2000, all of Mr. Taub's stock of CECO, aggregating 441,297 shares for $2.125 per share and 124,703 shares of Hilary Taub's, Mr. Taub's former wife, stock of CECO, aggregating 124,703 shares for $2.125 per share.

Andrew Halapin, former President of Busch, is the beneficial owner of the building in which Busch leases its principal office. The lease is a triple net lease, with annual rent in the amount of $85,694. CECO purchased shares of Peerless stock in 1999. Part of the funds used to purchase such stock were borrowed from Can-Med. Can-Med is owned 50.1% by Icarus, which is owned 50% by Phillip DeZwirek (the Chairman of the Board of Directors and Chief Executive Officer of CECO) and 50% by Jason DeZwirek (a director and the Secretary of CECO).

Can-Med provided $4,000,000 of the subordinated debt. The promissory notes which were issued to evidence the subordinated debt provide that they accrue interest at the rate of 12% per annum, payable semi-annually, subject to the subordination agreement with the banks providing the Bank Facility. In consideration for the subordinated lenders making CECO the subordinated loans, CECO issued to the subordinated lenders warrants to purchase up to 1,000,000 shares of CECO's common stock for $2.25 per share, the closing price of CECO's common stock on the day that the subordinated lenders entered into an agreement with CECO to provide the subordinated loans. Can-Med was issued 800,000 of such warrants. The warrants are exercisable from June 6, 2000 until December 7, 2009. The subordinated lenders, including Can-Med, were granted certain registration rights with respect to their warrants and shares of common stock of CECO into which the warrants are convertible. 7

The following table summarizes the total compensation of the former Chief Executive Officer of CECO Filters, Inc. for 2000 and the two previous years. Summary Compensation Table For Filters: Annual Compensation Name/Principal Position Year Salary All Other Compensation ----------------------- ---- ------ ---------------------- Steven I. Taub, Ph.D./ 2000 $123,318(1) $83,928(2) President and 1999 $247,603 $5,000 Chief Executive 1998 $240,740 $4,750 Officer - ------ (1) $112,500 is allocated to base salary and the remainder to an IRA contribution, automobile allowance and insurance premiums, all of which items Dr. Taub pays for directly. (2) Represents $2,524 of a matching contribution by Filters to Filters' 401(k) Plan on behalf of Dr. Taub and $81,404 in severance pay. Steven Taub's employment with Filters was terminated as of June 30, 2000 pursuant to a Separation Agreement and General Release (the "Agreement"). Under the terms of the Agreement Mr. Taub agrees that for a period commencing on June 30, 2000 and continuing until October 28, 2001, Mr. Taub will not, within the continental United States, directly or indirectly engage in certain competitive businesses. If Mr. Taub is presented with or finds an opportunity for CECO or its affiliates at any time within one year from October 28,2000, Mr. Taub must first present such opportunity to CECO. In addition, all options to purchase stock of CECO held by Mr. Taub were terminated as of June 30, 2000. CECO, pursuant to the Agreement, purchased on July 5, 2000, all of Mr. Taub's stock of CECO, aggregating 441,297 shares for $2.125 per share and 124,703 shares of Hilary Taub's, Mr. Taub's former wife, stock of CECO, aggregating 124,703 shares for $2.125 per share. In addition, through October 28, 2000, Mr. Taub was paid $678.37 per day from Filters. Filters also agreed to pay all of Mr. Taub's major medical insurance costs through October 28, 2000. PROPOSAL II REINCORPORATING IN DELAWARE On September 5, 2001 the Board of Directors adopted a plan, subject to approval by the stockholders, to reincorporate CECO under the laws of the State of Delaware. CECO was incorporated under the laws of New York in 1966, but the Board believes Delaware corporate law will better serve the stockholders' interests and provide CECO with advantages not available under New York corporate law. Therefore, CECO will ask stockholders at the Annual Meeting to approve the form of the Certificate of Merger which appears as an Exhibit A at the end of this Proxy Statement. Such transaction is commonly called a "reincorporation." CECO will continue to be called CECO Environmental, Inc. after the reincorporation. To explain the proposal, however, this Proxy Statement will call CECO that exists today as a New York corporation either "CECO" or "CECO-New York" and for convenience "CECO-Delaware" refers to the new Delaware corporation that will be organized. If the holders of at least two-thirds of all outstanding shares of the Common Stock approve the Merger Agreement, CECO-New York will be merged into CECO-Delaware. The effective date will be when the necessary 11

documents have been filed in both New York and Delaware. CECO-Delaware will be the surviving corporation, and the charter and by-laws of the new corporation will be substantially the same as those of CECO-New York today. Reasons for the Change For many years, Delaware has encouraged incorporation in that state by adopting modern, comprehensive and flexible corporate laws, and it periodically updates and revises them to meet changing business needs. The Delaware General Corporation Law is considered a sophisticated statute, highly conducive to business. That is why many corporations choose Delaware initially as their place of incorporation, and why many others have reincorporated in Delaware by means of transactions like the one now proposed. Because of Delaware's policy of encouraging incorporation and its preeminence as the most popular state of incorporation for major corporations, the courts of Delaware have developed considerable expertise in dealing with corporate issues. As a result, Delaware's case law interpreting its corporate laws is more developed than that of any other state. This gives Delaware corporate law an extra measure of predictability that is useful and often critical in our precedent-based judicial system. For the board and the management of a Delaware corporation, these features of Delaware law allow greater certainty in managing the corporation. The state's court system also provides for relatively prompt resolution of most corporate disputes. For example, Delaware has a specialized Court of Chancery that hears cases involving corporate law. The Court of Chancery has no jurisdiction over most other kinds of cases, and therefore its dockets are not as backlogged as many other states. In addition, the Supreme Court of Delaware hears and decides important corporate appeals rapidly. The Board of Directors of CECO considered the predictability and flexibility of Delaware law and the efficiency of its judicial process when it recommended the present proposal. The Board also recognized the possibility that choosing to be governed by the corporate law of Delaware, as so many other corporations have done, may further enhance the reputation of CECO. Continuity of Business and other Factors CECO has carried on its business under the "CECO Environmental" trademark continuously since 1992. The merger into CECO-Delaware will not break this continuity. CECO-Delaware will have its principal corporate offices in Toronto at CECO-New York's current address, and will appoint a registered agent to represent it in Delaware. Reincorporation in Delaware will not change the business plan, management, assets, liabilities, net worth, capitalization or employee benefit plans of CECO. Furthermore, each incentive stock option that would be, or later become, exercisable for shares of CECO's Common Stock will automatically be, or later become, exercisable for the same number of shares of the common stock of CECO-Delaware on the same terms and conditions. Authorized shares of Capital Stock After the reincorporation, the authorized capital stock of CECO-Delaware will consist of 100,000,000 shares of common stock, par value $0.01 per share, and 10,000 shares of preferred stock, par value $0.01 per share. These figures are the same as those currently authorized for CECO-New York. CECO-Delaware will not issue any common stock or preferred stock in connection with the reincorporation, other than the shares which the old shares will convert into. The Board of Directors of CECO-Delaware will have authority to issue preferred stock in series, just as the Board of CECO-New York may do today. The Board will determine voting powers, designations, preferences, and relative rights, qualifications, limitations and restrictions on any preferred stock it may issue. 12

Conversion of Shares As soon as the reincorporation becomes effective, CECO-Delaware will issue a press release announcing that the transaction has occurred. At the same time, the holders of the old shares of CECO-New York will become holders of the new shares of CECO-Delaware. Shares of CECO-New York will automatically convert into shares of CECO-Delaware on these terms: o The conversion will be on a one-for-one basis. o Each share of the old Common Stock of CECO-New York which is outstanding at the effective date will become one share of the new common stock, par value $0.01 per share, of CECO-Delaware. THIS MEANS THAT, BEGINNING ON THE EFFECTIVE DATE, EACH CECO-NEW YORK STOCK CERTIFICATE WHICH WAS OUTSTANDING JUST BEFORE THE REINCORPORATION WILL AUTOMATICALLY REPRESENT THE SAME NUMBER OF CECO-DELAWARE SHARES. THEREFORE, STOCKHOLDERS OF CECO-NEW YORK NEED NOT EXCHANGE THEIR STOCK CERTIFICATES FOR NEW CECO-DELAWARE STOCK CERTIFICATES. LIKEWISE, STOCKHOLDERS SHOULD NOT DESTROY THEIR OLD CERTIFICATES AND SHOULD NOT SEND THEIR OLD CERTIFICATES TO CECO, EITHER BEFORE OR AFTER THE EFFECTIVE DATE OF REINCORPORATION, EXCEPT AS MAY BE APPROPRIATE UPON A REVERSE STOCK SPLIT AS DISCUSSED BELOW. Trading of the Stock After reincorporation, those who were formerly stockholders of CECO-New York may continue to make sales or transfers using their CECO-New York stock certificates. CECO-Delaware will issue new certificates representing shares of CECO-Delaware common stock for transfers occurring after the effective date. On request, CECO-Delaware will issue new certificates to anyone who holds CECO-New York stock certificates. Any request for new certificates will be subject to normal requirements including proper endorsement, signature guarantee, if required, and payment of applicable taxes. Stockholders whose shares of CECO-New York were freely tradable before the reincorporation will own shares of CECO-Delaware which are freely tradable after reincorporation. Similarly, any stockholder holding securities with transfer restrictions before reincorporation will hold shares of CECO-Delaware which have the same transfer restrictions after reincorporation. For purposes of computing the holding period under Rule 144 of the Securities Act of 1933, as amended, those who hold CECO-Delaware stock certificates will be deemed to have acquired their shares on the date they originally acquired their shares in CECO-New York. After the reincorporation, CECO-Delaware will continue to be a publicly held company. CECO-Delaware intends to list its common stock on Nasdaq. It will also file with the Securities and Exchange Commission and provide to its stockholders the same types of information that CECO-New York has previously filed and provided. Vote Required for Approval Approval of the form of the Merger Agreement and reincorporation in Delaware will require the affirmative vote of the holders of two-thirds of the outstanding Common Stock. As of the record date for the Annual Meeting, the current Directors and Officers of CECO control the right to vote 3,118,832 13

shares, representing 39.5% of the outstanding Common Stock, and have advised CECO that their present intent is to vote in favor of the proposal to reincorporate in Delaware. Certain Federal Income Tax Consequences The following is a brief summary of the principal federal income tax consequences of reincorporation under current law to holders of CECO's Common Stock. This summary is for general information only. It does not address potential legislative changes that may affect these consequences, and it does not address any state, local or foreign tax consequences of reincorporation. CECO has not obtained, and does not intend to obtain, a ruling from the Internal Revenue Service to the effect that the reincorporation is nontaxable. Neither CECO nor its stockholders will recognize any gain or loss by reason of the reincorporation. The tax basis of CECO-Delaware common stock received by a stockholder of CECO-New York through the reincorporation will be the same as the tax basis of CECO-New York Common Stock prior to reincorporation. A stockholder of CECO-New York who holds the stock as a capital asset should include the period he or she has held the Common Stock in determining the holding period for his or her CECO-Delaware stock. STOCKHOLDERS SHOULD CONSULT THEIR PERSONAL TAX ADVISORS TO DISCUSS THEIR OWN TAX SITUATIONS AND ANY POTENTIAL CHANGES IN FEDERAL, STATE AND LOCAL LAWS AND OTHER APPLICABLE TAX MATTERS RELATING TO REINCORPORATION. Comparison of the New York and Delaware Corporate Laws After reincorporation, the stockholders will become stockholders of CECO-Delaware. There are, of course, differences between the New York and Delaware corporate laws which may affect stockholders. A summary of the principal differences between the two bodies of law appears at pages__ through __ of this Proxy Statement. The comparison is not a substitute for direct reference to the actual laws or for professional interpretation of them. Abandonment If the Board of Directors decides not to proceed with the reincorporation at any time before the reincorporation becomes effective, the Board will have the right to abandon the Merger Agreement and take no further action towards reincorporating CECO in Delaware. THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" APPROVAL OF THE PLAN TO REINCORPORATE CECO IN DELAWARE. PROPOSAL III REVERSE STOCK SPLIT AND INCREASE OF AUTHORIZED SHARES The Board unanimously has approved, and recommends to the holders of the Common Stock that they approve (i) a one-for-three reverse stock split of CECO's Common Stock, par value $0.01 per share, whereby each outstanding share of Common Stock will be reclassified into one-third of a new share of Common Stock (the "Reverse Stock Split") and (ii) an increase in the number of authorized shares of Common Stock from 33,333,333.33 to 50,000,000 immediately following the Reverse Stock Split (the "Stock Increase"). If approved by the 14

stockholders, the Reverse Stock Split and Stock Increase may be effected, as described below. The Reverse Stock Split will occur after the reincorporation of CECO to Delaware and the Stock Increase will occur immediately after the Reverse Stock Split. The intent of the Reverse Stock Split is to reduce the number of shares of Common Stock outstanding and to increase the marketability and liquidity of the Common Stock. If the Reverse Stock Split is approved by the holders of the Common Stock at the Annual Meeting, the Reverse Stock Split will be effected unless there is a subsequent determination by the Board that the Reverse Stock Split is not in the best interests of CECO and its stockholders. Although the Board believes as of the date of this Proxy Statement that the Reverse Stock Split and Stock Increase is advisable, the Reverse Stock Split and the Stock Increase may be abandoned by the Board at any time before, during or after the Annual Meeting and prior to filing the proposed amendment to the Certificate of Incorporation, as set forth in Exhibit B to this Proxy Statement. The Stock Increase will not occur unless the Reverse Stock Split is effected. The discussion of the Reverse Stock Split and the Stock Increase set forth below is qualified in its entirety by reference to Exhibits B and C, which are incorporated herein by reference. Purposes of the Reverse Stock Split The principal purpose of the Reverse Stock Split is to reduce the number of shares of Common Stock outstanding. The Board believes that the total number of shares currently outstanding is disproportionately large relative to CECO's present market capitalization. The purpose of the Stock Increase is to give CECO flexibility in the future to issue additional shares. The Board of Directors believes that a decrease in the number of authorized shares of Common Stock, without any material alteration of the proportionate economic interest in CECO held by individual stockholders, may increase the trading price of the outstanding shares to a price more appropriate for a Nasdaq listed security, although no assurance can be given that the market price of the Common Stock will rise in proportion to the reduction in the number of outstanding shares resulting from the Reverse Stock Split. Additionally, the Board of Directors believes that the current per share price of the Common Stock may limit the effective marketability of the Common Stock because of the reluctance of many brokerage firms and investors to recommend lower priced stocks to their clients or to hold them in their own portfolios. Certain policies and practices of the securities industry may tend to discourage individual brokers within those firms from dealing in lower-priced stocks. Some of those policies and practices involve time-consuming procedures that make the handling of lower-priced stocks economically unattractive. The brokerage commission on a sale of lower-priced stock may also represent a higher percentage of the sale price than the brokerage commission on a higher-priced issue. Any reduction in brokerage commissions resulting from the Reverse Stock Split may be offset, however, in whole or in part, by increased brokerage commissions required to be paid by stockholders selling "odd lots" created by the Reverse Stock Split. The current price per share price of the Common Stock may also limit potential financial institutions from lending funds to or otherwise investing in CECO. The Board of Directors believes that the higher share price that may result from the Reverse Stock Split will help generate interest in the Company among investors, thereby facilitating future financings. The Board believes that the decrease in the number of shares of Common Stock outstanding as a consequence of the proposed Reverse Stock Split and the resulting anticipated increased price level may encourage greater interest in the Common Stock by the financial community and possibly promote greater 15

liquidity for the holders of the Common Stock. It also is expected to increase the CECO's attractiveness to investors in connection with an attempt made by CECO to raise capital. It is possible, however, that liquidity could be affected adversely by the reduced number of shares outstanding after the reverse Stock Split. Although any increase in the market price of the Common Stock resulting from the Reverse Stock Split may be proportionately less than the decrease in the number of shares outstanding, the proposed Reverse Stock Split could result in a market price for the shares that would be high enough to overcome the reluctance, policies and practices of financial institutions and investors and to diminish the adverse impact of correspondingly high trading commissions on the market for the shares. There can also be no assurances, however, that the foregoing effects will occur or that the market price of the Common Stock immediately after the implementation of the proposed Reverse Stock Split will be maintained for any period of time, or that such market price will approximate three times the market price before the proposed Reverse Stock Split. Effect Of The Reverse Stock Split If the Reverse Stock Split is approved by the holders of Common Stock at the Annual Meeting, and unless there is a subsequent determination by the Board of Directors that the Reverse Stock Split is not in the best interests of CECO and its stockholders, an amendment to Article IV of the Certificate of Incorporation, in the form set forth in Exhibit B hereto, would be filed with the Secretary of State of the State of Delaware on any date (the "Reverse Stock Split Date") selected by the Board on or prior to CECO's next annual meeting of stockholders, however, such date would occur after the reincorporation of CECO to Delaware. The Reverse Stock Split would become effective as of 5:00 p.m. on the date of such filing. Without any further action on the part of CECO or the holders of the Common Stock, the shares of Common Stock held by stockholders of record as of the Reverse Stock Split would be converted at 5:00 p.m. on the Reverse Stock Split Date into the right to receive an amount of whole shares of new Common Stock equal to the number of their shares divided by five. The number of authorized shares of Common Stock would be reduced from 100,000,000 to 33,333,333.33; however, another amendment to Article IV of the Certificate of Incorporation, in the form set forth in Exhibit C hereto, will provide that the number of authorized shares of Common Stock following the Reverse Stock Split will be raised to 50,000.000. No fractional shares would be issued, and no such fractional share interest would entitle the holder thereof to vote or to any rights of a stockholder of CECO. In lieu of any such fractional shares, fractional shares shall be rounded up. Approval of the Reverse Stock Split would not affect any continuing stockholder's percentage ownership interest in CECO or proportional voting power, except for minor differences resulting from the rounding up of fractional shares. The shares of Common Stock which would be issued upon approval of the Reverse Stock Split would be fully paid and nonassessable. The voting rights and other privileges of the continuing holders of Common Stock would not be affected substantially by adoption of the Reverse Stock Split or subsequent implementation thereof. The par value of the Common Stock would remain at $0.01 per share following the Reverse Stock Split, and the number of shares of Common Stock outstanding would be reduced. As a consequence, the aggregate par value of the outstanding Common Stock would be reduced, while the aggregate capital in excess of par value attributable to the outstanding Common Stock for statutory and accounting purposes would be correspondingly increased. Under Delaware law, the Board would have the authority, subject to 16

certain limitations, to transfer some or all of such capital in excess of par value from capital to surplus, which could be distributed to stockholders as dividends or used by CECO to repurchase outstanding stock. CECO has no plans to reduce capital at this time. The Common Stock is listed for trading on Nasdaq-scm. The number of holders of the Common Stock on the Record Date was approximately 1850. CECO does not currently anticipate that the Reverse Stock Split would result in a material reduction in the number of holders. As of September 1, 2001, the number of issued and outstanding shares of Common Stock was 7,898,403 and 763,920 outstanding shares were held by CECO as treasury shares. As a result of the Reverse Stock Split and immediately following the Reverse Stock Split, the aggregate number of shares of Common Stock that would be issued and outstanding would be 2,632,801, of which 254,640 shares would be held as treasury shares and 48,420,319 shares would be authorized and unissued. Dissenting stockholders have no appraisal rights under Delaware law or under CECO's Certificate of Incorporation or By-laws in connection with the Reverse Stock Split. Pursuant to the terms of the Plan, the total number of shares reserved for grants and all options granted under the Plan would be reduced proportionately. All options granted under the Plan also would be reduced proportionately. The cash consideration payable per share upon exercise of the options pursuant to these plans would be increased proportionately. Similarly, the total number of shares issuable upon exercise of the outstanding warrants would be decreased proportionately and the cash consideration payable per share upon exercise of such warrants would increase proportionately. Pursuant to the terms of the Stock Plan, all stock granted under the Stock Plan also would be reduced proportionately. The following table illustrates the principal effects of the proposed Reverse Stock Split, as September 1, 2001: Number of Shares of Common Stock: Prior to Reverse Stock Split: After Reverse Stock Split: - --------------------------------- ----------------------------- -------------------------- Authorized............................................... 100,000,000 50,000,000(1) Outstanding.............................................. 8,662,323 2,887,441 Issued and Outstanding................................... 7,898,403 2,632,801 Reserved for issuance upon exercise of options granted under the Plan........................... 130,000 43,333 Reserved for issuance upon exercise of outstanding warrants..................................... 4,250,000 1,416,667 Reserved for issuance in connection with future grants under the Plan............................. 1,370,000 456,667 Reserved for issuance in connection with stock purchases under the Stock Plan..................... 961,068 320,356 Available for future issuance by action of the Board (after giving effect to the reservations above).......... 84,626,609 44,875,536 - ------ (1) The number of shares of authorized Common Stock after the Reverse Stock Split reflects an increase of authorized shares from 33,333,333.33 to 50,000,000 in accordance with the amendment to the Certificate of Incorporation set forth in Exhibit C. 17

Exchange Of Stock Certificates If the Reverse Stock Split is consummated, as soon as practicable after the Reverse Stock Split Date, CECO will send a letter of transmittal to each stockholder of record on the Reverse Stock Split Date for use in transmitting certificates representing shares of Common Stock ("Old Certificates") to CECO's exchange agent, American Stock Transfer and Trust Company (the "Exchange Agent"). The letter of transmittal will contain instructions for the surrender of Old Certificates to the Exchange Agent in exchange for certificates representing the appropriate number of whole shares of new Common Stock. No new certificates will be issued to a stockholder until such stockholder has surrendered all Old Certificates together with a properly completed and executed letter of transmittal to the Exchange Agent. Upon proper completion and execution of the letter of transmittal and return thereof to the Exchange Agent, together with all Old Certificates, stockholders will receive a new certificate or certificates representing the number of whole shares of new Common Stock into which their shares of Common Stock represented by the Old Certificates have been converted as a result of the Reverse Stock Split. Until surrendered, outstanding Old Certificates held by stockholders will be deemed for all purposes to represent the number of whole shares of Common Stock to which such stockholders are entitled as a result of the Reverse Stock Split. Stockholders should not send their Old Certificates to the Exchange Agent until they have received the letter of transmittal. Shares not presented for surrender as soon as practicable after the letter of transmittal is sent shall be exchanged at the first time they are presented for transfer. No service charges will be payable by holders of shares of Common Stock in connection with the exchange of certificates, all expenses of which will be borne by CECO. Federal Income Tax Consequences The following is a summary of the material anticipated Federal income tax consequences of the Reverse Stock Split to stockholders of CECO. This summary is based on the Federal income tax laws now in effect and as currently interpreted. It does not take into account possible changes in such laws or interpretations, including amendments to applicable statutes, regulations and proposed regulations or changes in judicial or administrative rulings, some of which may have retroactive effect. This summary is provided for general information only and does not purport to address all aspects of the possible Federal income tax consequences of the Reverse Stock Split and is not intended as tax advice to any person. In particular, and without limiting the foregoing, this summary does not consider the Federal income tax consequences to stockholders of CECO in light of their individual investment circumstances or to holders subject to special treatment under the Federal income tax laws (for example, life insurance companies, regulated investment companies and foreign taxpayers). The summary does not discuss any consequence of the Reverse Stock Split under any state, local or foreign tax laws. No ruling from the Internal Revenue Service or opinion of counsel will be obtained regarding the Federal income tax consequences to the stockholders of CECO as a result of the Reverse Stock Split. ACCORDINGLY, EACH STOCKHOLDER IS ENCOURAGED TO CONSULT HIS OR HER TAX ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES OF THE PROPOSED REVERSE STOCK SPLIT TO SUCH STOCKHOLDER, INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS. CECO believes that the Reverse Stock Split would be a tax-free recapitalization to CECO and its stockholders. If the Reverse Stock Split qualifies as a recapitalization described in Section 36(a)(1)(E) of the Internal Revenue Code of 1986, as amended (the "Code"), (i) no gain or loss will be recognized by holders of Common Stock who exchange their Common Stock for new Common Stock, (ii) the tax basis of the new Common Stock received by holders of 18

Common Stock will be the same as the tax basis of the Common Stock exchange therefor, less the tax basis allocated to fractional share interests and (iii) the holding period of the new Common Stock in the hands of holders of new Common Stock will including the holding period of their Common Stock exchanged therefor, provided that such Common Stock was held as a capital asset immediately prior to the exchange. Vote Required For Approval The approval of the Reverse Stock Split and increase in authorized shares of Common Stock requires the affirmative vote of a majority of the outstanding shares of Common Stock. THE BOARD RECOMMENDS THAT YOU VOTE "FOR" THE PROPOSED REVERSE STOCK SPLIT AND INCREASE IN AUTHORIZED SHARES OF COMMON STOCK. PROPOSAL IV APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS Subject to ratification by the stockholders at the Annual Meeting, the Board of Directors has appointed Deloitte & Touche LLP ("Deloitte") to serve as the independent public accountants of CECO for its fiscal year ending December 31, 2001. Deloitte was engaged to act as CECO's public accountants on September 28, 2000. Accordingly, the engagement of Margolis & Company P.C. ("Margolis") was discontinued effective September 28, 2000. Margolis served as the independent public accountants of CECO since 1993. Notwithstanding the appointment, the Board of Directors, in its discretion, may direct appointment of new independent auditors at any time during the year, if the Board of Directors believes that such a change would be in the best interests of CECO and its stockholders. Neither representatives of Deloitte nor Margolis are expected to be present at the Annual Meeting. If the appointment of Deloitte is not ratified by the stockholders, the Board of Directors will appoint other independent public accountants. The reports of Margolis on CECO's consolidated financial statements for fiscal year ended December 31, 1999 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. In connection with the audits of CECO's consolidated financial statements for each of the two fiscal years ended December 31, 1998 and December 31, 1999 and the subsequent interim period prior to June 30, 2000, there were no disagreements between CECO and Margolis on any matters of accounting principles or practices, financial statement disclosure, or audit scope and procedures which, if not resolved to the satisfaction of Margolis, would have caused Margolis to make reference to the matter in their reports. CECO did not consult with Deloitte during the last two fiscal years in the period ended December 31, 1999 or the subsequent interim period prior to June 30, 2000 on either the application of accounting principles or type of opinion Deloitte might issue on CECO's financial statements. CECO reported the change in principal accountants on a Current Report on Form 8-K filed September 29, 2000. CECO provided Margolis with a copy of the disclosures it made in the Current Report on Form 8-K prior to the filing of the report with the Securities and Exchange Commission. Margolis has furnished CECO a copy of a letter addressed to the Securities and Exchange Commission stating that Margolis agrees with the statements made by CECO in this Proxy Statement. The affirmative vote of a majority of the votes cast on this proposal at the Annual Meeting with a quorum present is required to approve this proposal. 19

Audit Fees Margolis billed CECO $20,598 for the professional services rendered for the revision of its opinion included in the audit of CECO's annual financial statements for fiscal year 2000 and for reviews of the financial statements included in CECO's Quarterly Reports on Form 10QSB filed for the first two quarters of 2000. Deloitte billed CECO $127,687 for the professional services rendered for the audit of CECO's annual financial statements for fiscal year 2000 and the reviews of the financial statements included in CECO's Quarterly Reports on Form 10QSB filed for the third quarter of 2000. Financial Information Systems Design and Implementation Fees Neither Margolis nor Deloitte rendered professional services for the design and implementation of financial information systems to CECO during fiscal year 2000. All Other Fees Deloitte billed CECO $46,920 for all professional services rendered during fiscal year 2000 other than audits, reviews and financial information systems design and implementation. The Audit Committee has considered whether the provision of services by Deloitte other than the audit of the financial statements of CECO for the fiscal year 2000 and the review of the financial statements for the third quarter of the fiscal year 2000 is compatible with maintaining Deloitte's independence. THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS INDEPENDENT PUBLIC ACCOUNTANTS OF CECO FOR FISCAL YEAR 2001. ADDITIONAL INFORMATION Comparison Of New York And Delaware Corporate Laws If Proposal "II" is approved by the holders of at least two-thirds of CECO's outstanding Common Stock, and if CECO reincorporates in Delaware as outlined in this Proxy Statement, then the Stockholders of CECO ("CECO-New York," that is) will become stockholders of the new Delaware corporation, "CECO-Delaware." There are differences between the Business Corporation Law of New York ("BCL") and the General Corporation Law of Delaware ("DGCL") which will affect the rights of Stockholders in certain respects. Some of these differences define the particular provisions a corporation may choose to put into its certificate of incorporation, commonly called the "charter," and other differences may not affect CECO. The following summary is not a substitute for direct reference to the statutes themselves or for professional interpretation of them. Amendment of Charter Both the BCL and the DGCL allow a board of directors to recommend a charter amendment for approval by stockholders, and a majority of the shares entitled to vote at a stockholders' meeting are normally enough to approve that amendment. Both laws require that a majority of the holders of any particular 20

class of stock must approve the amendment if it would have an adverse effect on the holders of that class. In addition, both laws allow a corporation to require a vote larger than a majority on special types of issues. Amendment of By-laws The by-laws of CECO-New York provide, as permitted by the BCL, that the Board of Directors may amend, adopt or repeal CECO's by-laws. Under the DGCL, however, the board may amend, adopt or repeal by-laws only if permitted by the charter. The charter of CECO-Delaware will specifically permit amendment of the by-laws by the board. Additionally, both the BCL and the DGCL allow stockholders to further amend or repeal by-laws adopted or amended by the board. Special Meetings of Stockholders Under both the BCL and the DGCL, the board of directors or anyone authorized in the charter or by-laws may call a special meeting of stockholders. Currently the by-laws of CECO-New York allow the Board, the Chief Executive Officer or the President to call a special meeting, and the provision in the by-laws of CECO-Delaware will be comparable. Corporate Action Without Stockholders' Meeting The BCL and DGCL differ about whether corporate action can be taken by written consent and without a stockholders' meeting. Under the BCL, the holders of at least the minimum number of votes required to authorize such an action may take the action if the corporation's charter allows this, but otherwise the consent must be unanimous. The DGCL, on the other hand, lets stockholders take action by the written consent of at least the minimum number of votes required to act at a stockholders' meeting, unless the charter forbids it. Inspection of Stockholders List The BCL limits the right of a stockholder to inspect the list of record stockholders depending on the number of shares held and the length of ownership. But under the DGCL, any stockholder may inspect the stockholders' list for any purpose reasonably related to the person's interest as a stockholder. In addition, for at least ten days prior to each stockholders' meeting, a Delaware corporation must make available for examination a list of stockholders entitled to vote at the meeting. Vote Required for Certain Transactions Until February 1998, the BCL required the holders of two-thirds of the outstanding stock of a New York corporation to approve certain mergers, consolidations or sales of all or substantially all the corporation's assets that may occur outside the ordinary course of business. Since February 1998, however, a New York corporation may provide in its charter that the holders of a majority of the outstanding stock may approve such transactions, although CECO has not adopted such a charter provision. Under the DGCL, on the other hand, holders of a majority of the outstanding stock entitled to vote on such transactions have the power to approve a merger, consolidation or sale of all or substantially all the assets without a special provision in the charter, unless the charter provides otherwise. Furthermore, in the case of a merger under the DGCL, stockholders of the surviving corporation do not have to approve the merger at all, unless the charter provides otherwise, if these three conditions are met: o No amendment of the surviving corporation's charter is made by the merger agreement; and 21

o Each share of the surviving corporation's stock outstanding or in the treasury immediately prior to the effective date of the merger is to be an identical outstanding or treasury share of the surviving corporation after the effective date; and o The merger results in no more than a 20% increase in its outstanding common stock. Special vote requirements may apply to certain business combinations with interested stockholders. See the discussion of these below under the heading "Business Combinations with Interested Stockholders." Classification of Directors Both laws permit "classified" boards of directors, which means the directors have staggered terms that do not all expire at once. The BCL permits as many as four classes, the DGCL only three. CECO now has one class of directors, and CECO-Delaware will also have one. In order to give stockholders of CECO-Delaware the same protections as those currently available in CECO-New York, the charter of the Delaware corporation will state that any change in the classification of the board will require a two-thirds vote of the stockholders. This may help to prevent unwarranted removal of directors, as discussed below under the heading "Removal of Directors." Removal of Directors Under the BCL, directors may be removed by the stockholders for cause, or by either the stockholders or the directors if the charter so provides. CECO's present charter does provide that directors may be removed either by stockholders or by the Board, as long as there is cause. After the reincorporation, directors under the DGCL would generally be subject to removal with or without cause by a majority of the stockholders, unless the charter provides otherwise, but in a Delaware corporation with a classified board, directors can be removed only for cause. Therefore, the charter of CECO-Delaware will be written so as to give the same protections as those currently provided in the charter of CECO-New York, and any attempt to remove directors will require cause and a two-thirds vote of the stockholders. Limitation of Directors' Liability Both states permit the limitation of a director's personal liability while acting in his or her official capacity. Under the BCL, a director is not liable to the corporation or to its stockholders for monetary damages if the director has acted in good faith and with the same degree of care that an ordinarily prudent person would exercise in similar circumstances. The DGCL, on the other hand, requires a charter provision in order to limit a director's liability for breach of his or her fiduciary duty to the corporation. CECO's current charter limits monetary liability to the fullest extent permitted by the BCL, and the charter of CECO-Delaware will likewise limit such liability to the fullest extent permitted by the DGCL. But in some cases directors may be liable despite these limitations. Under the BCL, for example, a director is not immune from liability if he or she violates applicable statutes which expressly make directors liable. The DGCL forbids any limitation of liability if the director breached his or her duty of loyalty to the corporation or its stockholders, or if he or she failed to act in good faith, received an improper personal benefit from the corporation, or authorized a dividend or stock repurchase that was forbidden by the DGCL. 22

Indemnification of Directors and Officers; and Insurance With some variations, both the BCL and the DGCL allow a corporation to "indemnify," that is, to make whole, any person who is or was a director, officer, employee or agent of the corporation if that person is held liable for something he or she did or failed to do in an official capacity. Besides covering court judgments, out-of-court settlements, fines and penalties, both laws also allow the corporation to advance certain reasonable expenses the person will incur or to reimburse the person's expenses after he or she incurs them, even if liability is not actually proven. The right to indemnification under both laws does not normally exclude other rights of recovery the indemnified person may have. Additionally, each of the two laws permits a corporation to purchase insurance for its directors, officers, employees and agents against some or all of the costs of such indemnification or against liabilities arising from actions and omissions of the insured person, even though the corporation may not have power to indemnify the person against such liabilities. The BCL, however, restricts the kinds of claims that may be made under insurance purchased by the corporation against these liabilities. For example, there would be no insurance coverage if the person to be indemnified was guilty of deliberate dishonesty and that dishonesty was material to the event that produced the claim, or if the person gained some financial profit or other advantage that he or she was not entitled to. The by-laws of CECO-New York currently indemnify to the fullest extent permitted by the BCL, and the by-laws of CECO-Delaware will indemnify as fully as the DGCL allows. However, neither the BCL nor the DGCL permit indemnification of a director, officer, employee or agent if a court finds the person liable to the corporation itself, unless the court determines otherwise. Furthermore, if the corporation sues the person because of some act or omission, the corporation does not need to indemnify the person unless a court determines the person was not liable. Furthermore, the DGCL generally requires that the person to be indemnified must have acted in good faith and in a manner he or she reasonably believed was consistent with the best interests of the corporation. If Proposal "II" is approved by CECO's Stockholders, the DGCL indemnification provisions will not apply to acts and omissions that occurred before the effective date of the reincorporation. The BCL will govern these. Loans and Guarantees of Obligations for Directors Under the BCL, the holders of a majority of the shares entitled to vote, excluding any shares of the director who is the proposed borrower, are required to approve any loans to, or guarantees of obligations of, a director. Under the DGCL, a board of directors may authorize loans or guarantees of indebtedness to employees, officers and directors. Issuance of Rights and Options to Directors, Officers and Employees Under the BCL, the issuance of any stock rights or stock options, as well as plans to issue rights or options, to directors, officers or employees must be approved by a majority of votes cast at a stockholders' meeting. The DGCL does not require stockholder approval of such transactions. However, the rules of the Nasdaq-scm, where CECO's stock is listed and where the stock of CECO-Delaware will be listed, require stockholder approval of option plans in certain circumstances. 23

Consideration for Shares Under the BCL, obligations for future services or payments are not considered payment or partial payment for shares of a corporation. Stock certificates cannot be issued until full payment has been made, except for shares purchased under a stock option plan permitting installment payments. Under the DGCL, however, a corporation can receive cash, services, personal or real property, leases of real property or any combination of these as payment in full or in part for the shares. A purchaser of shares under the DGCL may pay an amount equal to or greater than the par value of such shares if the corporation receives a binding obligation of the purchaser to pay the balance of the purchase price. Dividends, and Redemption of Stock Subject to its charter provisions, a corporation may generally pay dividends, redeem shares of its stock or make other distributions to stockholders if the corporation is solvent and would not become insolvent because of the dividend, redemption or distribution. The assets applied to such a distribution may not be greater than the corporation's "surplus." The BCL defines surplus as the excess of net assets over stated capital, and lets the board adjust stated capital. The DGCL, on the other hand, defines surplus as the excess of net assets over capital, and lets the board adjust capital. If there is no surplus, the DGCL allows the corporation to apply net profits from the current or preceding fiscal year, or both, unless the corporation's net assets are less than the capital represented by issued and outstanding stock which has a preference on any distribution of assets. Regarding redemptions, both the BCL and the DGCL permit them only when the corporation has outstanding shares of at least one class of voting stock which is not subject to the redemption. Appraisal Rights Generally, "appraisal rights" entitle dissenting stockholders to receive the fair value of their shares in the merger or consolidation of a corporation or in the sale of all or substantially all its assets. The BCL also extends appraisal rights to an exchange of a corporation's shares. Appraisal rights under the BCL allow any stockholder of a New York corporation, with various exceptions, to receive fair value for his or her shares in such transactions. However, the BCL provides that dissenting stockholders have no appraisal rights if they are a stockholder of the parent corporation in a merger between a parent and subsidiary or when a subsidiary corporation or the corporation owning at least 90% of the outstanding shares of each class of the subsidiary is a foreign corporation. Further, dissenting stockholders do not have appraisal rights if they are stockholders of a surviving corporation in a merger, unless the merger changes the rights of the shares held by such stockholder. Finally, dissenting stockholders do not have appraisal rights if their shares are listed on a national securities exchange or designated as a national market system security. Appraisal rights are generally available under BCL to a stockholder who does not assent to any plan of merger or consolidation to which the corporation is a party, except in the circumstances noted above, or to the sale, lease, exchange or other disposition of all or substantially all of the assets of a corporation requiring stockholder approval or to a share exchange in which the corporation is participating as a subject corporation. Further, appraisal rights are available to any shareholder of a subsidiary corporation in a merger of a parent and subsidiary or in s ahres exchange, who files a written notice of an election to dissent. Also, appraisal rights are available to stockholders who are not allowed to vote on a merger or consolidation and whose shares will be cancelled or exchanged for cash or something else of value other than shares of the surviving corporation or another corporation. When appraisal rights are available, the stockholder may have to request the appraisal and follow other required procedures. 24

Similarly, under the DGCL, appraisal rights are not available to a stockholder if the corporation's shares are listed on a national securities exchange or designated as a national market system security on an interdealer quotation system, or held by more than 2,000 stockholders of record, or if the corporation will be the surviving corporation in a merger which does not require the approval of the surviving corporation's stockholders. A dissenting stockholder in a merger or consolidation has appraisal rights under the DGCL if the transaction requires him or her to exchange shares for anything of value other than one or more of the following: o Shares of stock of the surviving corporation or of a new corporation which results from the merger or consolidation. o Shares of another corporation which will be listed on a national securities exchange or held by more than 2,000 stockholders of record after the merger or consolidation occurs. o Cash instead of fractional shares of the surviving corporation or another corporation. Business Combinations with Interested Stockholders Provisions in both laws may help to prevent or delay changes of corporate control. In particular, both the BCL and the DGCL restrict or prohibit an interested stockholder from entering into certain types of business combinations unless the board of directors approves the transaction in advance. Under the BCL, an interested stockholder is generally prohibited from entering into certain types of business combinations with a New York corporation for a period of five years after becoming an interested stockholder, unless the board of directors approved either the business combination or the acquisition of stock by the interested stockholder before the interested stockholder acquired his or her shares. An "interested stockholder" under the BCL is generally a beneficial owner of at least 20% of the corporation's outstanding voting stock. "Business combinations" under the BCL include mergers and consolidations between corporations or with an interested stockholder; sales, leases, mortgages or other dispositions to an interested stockholder of assets with an aggregate market value which either (1) equals 10% or more of the corporation's consolidated assets or outstanding stock, or (2) represents 10% or more of the consolidated earning power or net income of the corporation; issues and transfers of stock with an aggregate market value of at least 5% in relation to the outstanding stock of the corporation; liquidation or dissolution of the corporation proposed by or in connection with an interested stockholder; reclassification or recapitalization of stock that would increase the proportionate stock ownership of an interested stockholder; and the receipt by an interested stockholder of benefit from loans, guarantees, pledges or other financial assistance or tax benefits provided by the corporation. After the five-year period referred to in the BCL, the law allows such business combinations if either the board of directors or a majority of the outstanding voting stock not owned by the interested stockholder have approved the business combination or the purchase of stock by the interested stockholder before the interested stockholder acquired his or her shares. Business combinations are also permitted when certain statutory "fair price" requirements are met. One section of the DGCL, Section 203, generally prohibits an interested stockholder from entering into certain types of business combinations with a Delaware corporation for three years after becoming an interested stockholder. An "interested stockholder" under the DGCL is any person other than the corporation and its majority-owned subsidiaries who owns at least 15% of the outstanding voting stock, or who owned at least 15% within the preceding three 25

years, and this definition includes affiliates of the corporation. Briefly described, the prohibited combinations include: o Mergers or consolidations. o Sales, leases, exchanges or other dispositions of 10% or more of (1) the aggregate market value of all assets of the corporation or (2) the aggregate market value of all the outstanding stock of the corporation. o Issuances or transfers by the corporation of its stock that would increase the proportionate share of stock owned by the interested stockholder. o Receipt by the interested stockholder of the benefit of loans, advances, guarantees, pledges or other financial benefits provided by the corporation. o Any other transaction, with certain exceptions, that increases the proportionate share of the stock owned by the interested stockholder. A Delaware corporation may choose not to have Section 203 of the DGCL apply. CECO has chosen, however, to accept the protections of Section 203, and therefore the charter of CECO-Delaware will not waive those protections. Nevertheless, Section 203 will not apply in the following cases: o If, before the stockholder became an interested stockholder, the board of directors approved the business combination or the transaction that resulted in the stockholder becoming an interested stockholder. o If, after the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, subject to technical calculation rules. o If, on or after the time the interested stockholder became an interested stockholder, the board of directors approved the business combination, and at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder also ratified the business combination at a stockholders' meeting. OTHER MATTERS As of the date of this Proxy Statement, the Board of Directors knows of no matters which will be presented for consideration at the Annual Meeting other than the proposals set forth in this Proxy Statement. If any other matters properly come before the Annual Meeting, it is intended that the persons named in the proxy will vote the shares they represent as the Board of Directors may recommend. A copy of CECO's Annual Report on Form 10-KSB for the fiscal year ended December 31, 2000, as filed with the Securities and Exchange Commission, without exhibits, will be sent to any stockholder without charge upon written request addressed to CECO Environmental Corp., to the attention of the Secretary, 505 University Avenue, Toronto, Ontario, CANADA M5G 1X3. 26
