Pursuant to the Agreement and Plan of Merger, dated as of April 21, 2013 (as the same may be amended, modified or supplemented from time to time, the “Merger Agreement”), by and among Met-Pro Corporation (“Met-Pro”), CECO Environmental Corp. (“CECO”), Mustang Acquisition Inc. and Mustang Acquisition II Inc., you hereby surrender to American Stock Transfer & Trust Company, LLC, as exchange agent (the “Exchange Agent”), the certificate(s) (the “Met-Pro Certificate(s)”) representing common shares, $0.10 par value per share, of Met-Pro Corporation (“Met-Pro Shares”) owned of record by you as set forth herein, and hereby make the election (the “Election”), indicated in TABLE B (Election) below, to have the Met-Pro Shares evidenced by such Met-Pro Certificate(s) converted in the First Step Merger (as defined in the Merger Agreement) into the right to receive one (and only one) of the following:

•

Cash Election — $13.75 in cash, without interest, per Met-Pro Share (the “Cash Consideration”), subject to proration, as calculated in accordance with the Merger Agreement and described in the joint proxy statement/prospectus, dated [.], 2013, filed by CECO and Met-Pro with the Securities and Exchange Commission (the “Joint Proxy Statement/Prospectus”);

•

Stock Election —shares of CECO common stock, par value $0.01 per share (“CECO Shares”), having an equivalent value based on the volume weighted average trading price of CECO Shares on the NASDAQ Global Market for the fifteen (15) consecutive trading days ending on the trading day immediately preceding the closing date of the First Step Merger, per Met-Pro Share (including cash in lieu of any fractional CECO Share, the “Stock Consideration”), subject to (a) a collar so that there will be a maximum exchange ratio of 1.3520 CECO Shares for each Met-Pro Share and a minimum of 1.0000 CECO Shares for each Met-Pro Share and (b) proration, as calculated in accordance with the Merger Agreement and described in the Joint Proxy Statement/Prospectus; or

•

Mixed Election — Cash Consideration with respect to a portion of your Met-Pro Shares evidenced by the Met-Pro Certificate(s) as designated by you below in TABLE B (Election) and Stock Consideration with respect to the balance of your Met-Pro Shares evidenced by the Met-Pro Certificate(s), subject to proration, as calculated in accordance with the Merger Agreement and described in the Joint Proxy Statement/Prospectus.

If you do not mark one of the Election boxes below in TABLE B (Election), you will be deemed to have indicated no preference as to the receipt of Cash Consideration or Stock Consideration (a “Non-Election”) and will receive consideration in the First Step Merger (the “Merger Consideration”) that may be Cash Consideration for all of your Met-Pro Shares, Stock Consideration for all of your Met-Pro Shares, or Cash Consideration for some of your Met-Pro Shares and Stock Consideration for some of your Met-Pro Shares, depending on elections that have been made by other Met-Pro shareholders and based on the results of the proration procedures set forth in the Merger Agreement and described in the Joint Proxy Statement/Prospectus.

You understand that the Election is subject to certain terms, conditions and limitations set forth in the Merger Agreement and described in the Joint Proxy Statement/Prospectus. A copy of the Merger Agreement is attached to the Joint Proxy Statement/Prospectus as Annex A. These terms, conditions and limitations include, but are not limited to, the proration process, which is designed to ensure that the aggregate amount of Cash Consideration paid by CECO for Met-Pro Shares in the First Step Merger is equal to (a) the product of (i) $7.25 multiplied by (ii) the number of fully-diluted Met-Pro Shares (calculated using the treasury share method) issued and outstanding immediately prior to the closing of the First Step Merger minus (b) the aggregate cash consideration paid by CECO to discharge Met-Pro options and restricted stock units outstanding immediately prior to the closing of the First Step Merger (as described in more detail in the Joint Proxy Statement/Prospectus). On an overall fully-diluted basis, it is currently anticipated that approximately 53% of outstanding Met-Pro Shares will be converted into the right to receive the Cash Consideration, and approximately 47% of Met-Pro Shares will be converted into the right to receive the Stock Consideration. However, the exact proportions of Cash Consideration and Stock Consideration will not be determinable, and therefore will not be fixed, until the closing date of the First Step Merger. Accordingly, you may receive a form of Merger Consideration different from what you elect. You are urged to read the Merger Agreement and the Joint Proxy Statement/Prospectus in their entirety before completing this Form of Election and Letter of Transmittal.

1.

You agree that if you do not make an Election or if you make an improper Election for any Met-Pro Shares held by you, you will be deemed to have made a Non-Election and will receive Stock Consideration, Cash Consideration or a combination of both Stock Consideration and Cash Consideration, depending on the elections of other Met-Pro shareholders.

You also acknowledge that you were advised to make your own decision as to what Election to make based upon your own review of the Joint Proxy Statement/Prospectus.

INSTRUCTIONS

The Form of Election and Letter of Transmittal is to be completed by those record holders of Met-Pro Shares desiring to make an Election and must be received by the Exchange Agent at or prior to the Election Deadline. The Election Deadline will be 5:00 p.m., Eastern time (11:59 p.m., Eastern time for telephone and internet voting), on the date that is one (1) business day immediately prior to the special meeting of the shareholders of Met-Pro Corporation or such other date as CECO Environmental Corp. and Met-Pro Corporation mutually agree. If the special meeting date is delayed to a subsequent date, the Election Deadline will be similarly delayed to a subsequent date, and the rescheduled Election Deadline will be publicly announced. Holders of Met-Pro Shares who do not properly complete and submit the Form of Election and Letter of Transmittal at or prior to the Election Deadline cannot make an Election. They will be deemed to have made a Non-Election and will receive Merger Consideration that may be Cash Consideration for all of their Met-Pro Shares, Stock Consideration for all of their Met-Pro Shares, or Cash Consideration for some of their Met-Pro Shares and Stock Consideration for some of their Met-Pro Shares, depending on elections that have been made by other Met-Pro shareholders and subject to the results of the proration procedures set forth in the Merger Agreement and described in the Joint Proxy Statement/Prospectus. Until a record holder’s Met-Pro Certificate(s) (or confirmation of a book-entry transfer of the shares into the Exchange Agent’s account at DTC) is received by the Exchange Agent at either of the addresses set forth on the front of the Form of Election and Letter of Transmittal (or, solely with respect to a Guarantee of Delivery, the facsimile number set forth in the Notice of Guaranteed Delivery), together with any other documents the Exchange Agent may require, and until the same are processed for exchange by the Exchange Agent, such holder will not receive any certificate representing the Stock Consideration and/or check representing the Cash Consideration or check representing cash in lieu of any fractional CECO Share (if any) in exchange for the holder’s Met-Pro Certificate(s) or book entry. In addition, no interest will accrue on the Cash Consideration or any cash in lieu of any fractional CECO Share, and no dividends or any other distributions that are payable to holders of CECO shares as of a record date after the effective time of the First Step Merger will be paid to Met-Pro shareholders receiving Stock Consideration until the Exchange Agent has processed the holder’s Election.

1. Time in Which to Make an Election. For an Election to be validly made with respect to Met-Pro Shares owned by a holder, the Exchange Agent must receive, at either of the addresses set forth on the front of the Form of Election and Letter of Transmittal, at or prior to the Election Deadline, a Form of Election and Letter of Transmittal, properly completed and executed, and accompanied by the Met-Pro Certificate(s) representing such Met-Pro Shares, confirmation contained in an “Agent’s Message” of a book-entry transfer of the shares into the Exchange Agent’s account at DTC, or a Guarantee of Delivery. Any shareholder whose Form of Election and Letter of Transmittal and Met-Pro Certificate(s) (or confirmation of a book-entry transfer of the shares into the Exchange Agent’s account at DTC or Guarantee of Delivery) are not so received will be deemed to have made a Non-Election. If Met-Pro Certificate(s) representing Met-Pro Shares covered by a Guarantee of Delivery are not received (or if a confirmation contained in an “Agent’s Message” of a book-entry transfer of the Met-Pro Shares into the Exchange Agent’s account at DTC is not received) within three (3) NASDAQ trading days after the Election Deadline, the holder thereof will be deemed to have made a Non-Election. As used herein, the term “Agent’s Message” means a message, transmitted by DTC and received by the Exchange Agent and forming a part of a book-entry confirmation, which states that DTC has received an express acknowledgement from the DTC participant delivering the Met-Pro Shares, that such participant has received and agreed to be bound by the Form of Election and Letter of Transmittal, and that CECO may enforce such agreement against the participant.

2. Change or Revocation of Election. An Election may be revoked with respect to all or any portion of the Met-Pro Shares covered by the Election by the holder who submitted the applicable Form of Election and Letter of Transmittal, but only in whole share amounts by written notice of revocation received by the Exchange Agent at or prior to the Election Deadline. If an Election is revoked, or the Merger Agreement is terminated, and any Met-Pro Certificates have been transmitted to the Exchange Agent, the Exchange Agent will promptly return those Met-Pro Certificates to the shareholders who submitted them (except, in the case of a revocation, to the extent (if any) a subsequent cash election and/or stock election is properly made with respect to any or all of the Met-Pro Shares represented by such Met-Pro Certificates). Met-Pro shareholders will not be entitled to revoke or change their Elections following the Election Deadline. As a result, during the interval between the Election Deadline and the effective time of the First Step Merger, Met-Pro shareholders who have properly made Elections will not be able to revoke their elections or sell the Met-Pro Shares covered by their Elections. Once an Election is properly made with respect to any Met-Pro Shares, the electing shareholder will not be able to sell or otherwise transfer such Met-Pro Shares, unless the Election is properly revoked or the Merger Agreement is terminated.

3. Nominees. Record holders of Met-Pro Shares who are nominees only may submit a separate Form of Election and Letter of Transmittal for each beneficial owner for whom the record holder is a nominee; provided, however, that at the request of CECO the record holder must certify to CECO’s satisfaction that the record holder holds those Met-Pro Shares as nominee for the beneficial owner(s) thereof. Each beneficial owner for which a Form of Election and Letter of Transmittal is submitted will be treated as a separate holder of Met-Pro Shares.

4. Guarantee of Signatures. No signature guarantee is required on a Form of Election and Letter of Transmittal if it is signed by the record holder(s) of the Met-Pro Shares tendered herewith and the certificate representing CECO Shares and/or the check, if applicable, are to be issued to that record holder(s) without any correction or change in the name of the record holder(s). IN ALL OTHER CASES, ALL SIGNATURES ON A FORM OF ELECTION AND LETTER OF TRANSMITTAL MUST BE GUARANTEED. All signatures required to be guaranteed in accordance with these instructions must be guaranteed by a bank, broker or other institution that is a member of a Medallion Signature Guaranty Program (an “Eligible Institution”). Public notaries cannot execute acceptable guarantees of signatures.

5. Signatures on Form of Election and Letter of Transmittal, Stock Powers and Endorsements.

(a) If a Form of Election and Letter of Transmittal is signed by the record holder(s) of the Met-Pro Shares without any alteration, variation, correction or change in the name of the record holder(s), the signature(s) must correspond exactly with the name(s) as written on the face of the Met-Pro Certificate(s) or on the account records if you hold your Met-Pro Shares in book-entry form without any change whatsoever. If the name of the record holder(s) needs to be corrected or has changed (by marriage or otherwise), see Instruction 6.

(b) If any Met-Pro Shares tendered by a Form of Election and Letter of Transmittal are held of record by two or more joint holders, each of the joint holders must sign the Form of Election and Letter of Transmittal.

(c) If a Form of Election and Letter of Transmittal is signed by the record holder(s) of the Met-Pro Certificate(s) listed and transmitted thereby, no endorsements of the Met-Pro Certificate(s) or separate stock powers are required.

(d) If any surrendered Met-Pro Shares are registered in different names on several Met-Pro Certificate(s) or on the account records if you hold your Met-Pro Shares in book-entry form, it will be necessary to complete, sign and submit as many separate Forms of Election and Letters of Transmittal as there are different registrations of Met-Pro Certificate(s) or accounts holding Met-Pro Shares in book entry form.

(e) If a Form of Election and Letter of Transmittal is signed by a person(s) other than the record holder(s) of the Met-Pro Certificate(s) listed, the Met-Pro Certificate(s) must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name of the record holder(s) appears on the Met-Pro Certificate(s). Signatures on the Met-Pro Certificate(s) or stock powers must be guaranteed as provided in TABLE E (Shareholder(s) Sign Here) above. See Instruction 4.

(f) If a Form of Election and Letter of Transmittal or any Met-Pro Certificate(s) or stock power(s) is signed by a person(s) other than the record holder(s) of the Met-Pro Certificate(s) listed and the signer(s) is acting in the capacity of trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or any other person(s) acting in a fiduciary or representative capacity, that person(s) must so indicate when signing and must submit proper evidence satisfactory to the Exchange Agent of authority to so act.

6. Special Issuance and Delivery Instructions. Unless instructions to the contrary are given in TABLE C (Special Issuance Instructions) or TABLE D (Special Delivery Instructions), the certificate representing CECO Shares and/or the check to be distributed in exchange for Met-Pro Shares surrendered pursuant to a Form of Election and Letter of Transmittal or for fractional shares will be issued in the name and mailed to the address of the record holder(s) set forth in TABLE A (Description of Met-Pro Shares Surrendered). If the certificate and/or check are to be issued in the name of a person(s) other than the record holder(s) or if the name of the record holder(s) needs to be corrected or changed (by marriage or otherwise), TABLE C (Special Issuance Instructions) must be completed. If the certificate and/or check are to be sent to a person(s) other than the record holder(s) or to the record holder(s) at an address other than that shown in TABLE A (Description of Met-Pro Shares Surrendered), then TABLE D (Special Delivery Instructions)

must be completed. If TABLE C (Special Issuance Instructions) is completed, the signature(s) of the person(s) signing a Form of Election and Letter of Transmittal must be guaranteed as provided in TABLE E (Shareholder(s) Sign Here). See Instruction 4.

7. Important Information Regarding Backup Withholding. Each holder of Met-Pro Shares that is a United States person is required to provide the Exchange Agent with the holder’s correct Taxpayer Identification Number (“TIN”), generally the holder’s social security or federal employer identification number, on the Substitute Form W-9 provided herewith, or, alternatively, to establish another basis for exemption from backup withholding. A Met-Pro shareholder must cross out item (2) in Part II—Certification of the Substitute Form W-9 if such shareholder is subject to backup withholding. In addition to potential penalties, failure to provide the correct information on the Substitute Form W-9 may subject the shareholder to 28% federal income tax backup withholding on any reportable payments made to such shareholder. If the shareholder has not been issued a TIN and has applied for one or intends to apply for one in the near future, such shareholder should write “Applied For” in the space provided for the TIN in Part I of the Substitute Form W-9, and sign and date both the Substitute Form W-9 and the Certificate of Awaiting Taxpayer Identification Number. If “Applied For” is written in Part I and the Exchange Agent is not provided with a TIN by the time of payment, the Exchange Agent will withhold 28% from any payments of the Merger Consideration to such shareholder. A shareholder that is not a United States person may qualify as an exempt recipient by submitting to the Exchange Agent a properly completed Form W-8BEN, Form W-8ECI or Form W-8IMY, as applicable (which the Exchange Agent will provide upon request) signed under penalty of perjury, attesting to that shareholder’s exempt status.

8. Inadequate Space. If there is inadequate space to complete any box, the information must be set forth on additional sheets substantially in the form of the corresponding portion of this Form of Election and Letter of Transmittal and attached to the Form of Election and Letter of Transmittal.

9. Indication of Met-Pro Certificate(s) Numbers and Shares. TABLE A (Description of Met-Pro Shares Surrendered) of the Form of Election and Letter of Transmittal should indicate the certificate number(s) of the Met-Pro Certificate(s) surrendered therewith and the number of shares represented by each Met-Pro Certificate.

10. Method of Delivery. The method of delivery of all documents is at the option and risk of the holder of Met-Pro Shares. If delivery is by mail, the use of registered mail, with return receipt requested, properly insured, is strongly recommended. A return envelope is enclosed. Delivery of the documents will be deemed effective, and risk of loss and title with respect thereto will pass, only when the documents are actually received by the Exchange Agent.

11. Lost Met-Pro Certificate. If any Met-Pro Certificate has been lost, stolen or destroyed, the holder should notify Met-Pro’s transfer agent, American Stock Transfer & Trust Company, LLC, by calling 877-248-6417, e-mailing info@amstock.com or by writing to American Stock Transfer & Trust Company, LLC, Attention: Lost Securities Department 6201 15^th Ave., Brooklyn, NY 11219. The shareholder should include all pertinent information, including the certificate number, account number and the name of the stock. The fee to cover replacement is 3% of the market value of the shares, plus a $25.00 administrative fee. After the transfer agent receives notification, an Affidavit of Loss and Indemnity Agreement will be sent within 24 – 48 hours, by email, fax or regular mail. The replacement fee will be listed on the cover letter of the affidavit. Holders of Met-Pro Shares must properly complete, sign and send the Form of Election and Letter of Transmittal, and (unless the shares are held in book entry form) certificate(s) representing their Met-Pro Shares, or a Guarantee of Delivery as described in Instruction 14, to the Exchange Agent. The Exchange Agent must receive these documents at or prior to the Election Deadline. Accordingly, holders of Met-Pro Shares are urged to determine promptly if they require any replacement stock certificates.

12. Non-Consummation of the First Step Merger. Consummation of the First Step Merger is subject to the required approvals of the shareholders of Met-Pro and the stockholders of CECO, to the receipt of all required regulatory approvals and to the satisfaction or waiver of certain other conditions. No payment of any Merger Consideration will be made prior to the consummation of the First Step Merger, or if the Merger Agreement is terminated. If the Merger Agreement is terminated, all Elections will automatically be void and of no effect and Met-Pro Certificate(s) submitted to the Exchange Agent will be returned as soon as practicable to the persons submitting them.

13. Voting Rights and Dividends. Holders of Met-Pro Shares will continue to have the right to vote and to receive all dividends paid, if any, on all Met-Pro Shares deposited by them with the Exchange Agent until the First Step Merger is completed.

14. Guarantee of Delivery. Holders of Met-Pro Shares whose Met-Pro Certificate(s) are not immediately available or who cannot deliver their Met-Pro Certificate(s) and all other required documents to the Exchange Agent (and/or cannot complete the procedure for delivery of Met-Pro Shares by book-entry transfer into the Exchange Agent’s account at DTC) prior to the Election Deadline may deliver their Met-Pro Shares by properly completing and duly executing a Guarantee of Delivery if (1) the Guarantee of Delivery is made by or through a member of a registered national securities exchange, a member of the National Association of Securities Dealers, Inc. or by a commercial bank or trust company in the United States; (2) prior to the Election Deadline, the Exchange Agent receives a properly completed and duly executed Guarantee of Delivery, as provided herein, together with a properly completed and duly executed Form of Election and Letter of Transmittal and any other documents required by the Form of Election and Letter of Transmittal; and (3) the Met-Pro Certificate(s) for all the Met-Pro Shares covered by the Guarantee of Delivery, in proper form for transfer (or confirmation of a book-entry transfer of such Met-Pro Shares into the Exchange Agent’s account at DTC), are received by the Exchange Agent no later than 5:00 p.m. Eastern time on the third NASDAQ trading day after the Election Deadline. If the above requirements are not satisfied in a timely manner, the holder will be deemed to have made a Non-Election. The form of Guarantee of Delivery is enclosed herewith.

15. Construction. All Elections will be considered in accordance with the terms and conditions of the Merger Agreement.

All questions with respect to the Form of Election and Letter of Transmittal (including, without limitation, questions relating to the timeliness, effectiveness or revocation of any Election) will be resolved jointly by CECO and Met-Pro in their sole discretion and such resolution will be final and binding.

The Exchange Agent may (but is not required to) waive any immaterial defects or variances in the manner in which a Form of Election and Letter of Transmittal has been completed and submitted so long as the intent of the holder of Met-Pro Shares submitting the Form of Election and Letter of Transmittal is reasonably clear. None of the Exchange Agent, CECO or Met-Pro is under any obligation to provide notification of any defects in the deposit and surrender of any Met-Pro Certificate(s) or in the completion or submission of any Form of Election and Letter of Transmittal, nor shall any of the Exchange Agent, CECO or Met-Pro be liable for any failure to give any such notification.

16. Miscellaneous. No fraction of a CECO Share will be issued upon the surrender for exchange of any Met-Pro Shares. In lieu of any such fractional share, an amount of cash determined in accordance with the Merger Agreement will be paid by check.

Completing and returning the Form of Election and Letter of Transmittal does not have the effect of casting a vote with respect to the approval of the Merger Agreement and the transactions contemplated thereby, including the First Step Merger at the special meeting of shareholders of Met-Pro. To vote, please consult the Joint Proxy Statement/Prospectus.

17. Questions and Requests for Information. Questions and requests for information or assistance relating to the Form of Election and Letter of Transmittal should be directed to Morrow & Co., LLC, Met-Pro’s Proxy Solicitor, at:

Foreign payees who are not subject to backup withholding should complete an appropriate Form W-8 and return it to the payer.

Privacy Act Notice. Section 6109 requires you to provide your correct taxpayer identification number to payers who must file information returns with the IRS to report interest, dividends, and certain other income paid to you to the IRS. The IRS uses the numbers for identification purposes and to help verify the accuracy of your return and may also provide this information to the Department of Justice for civil and criminal litigation, and to cities, states, the District of Columbia and U.S. possessions to carry out their tax laws, and may also disclose this information to other countries under a tax treaty, or to Federal and state agencies to enforce Federal nontax criminal laws and to Federal law-enforcement and intelligence agencies to combat terrorism. Payers must be given the numbers whether or not recipients are required to file tax returns. Payers must generally withhold 28% of taxable interest, dividend, and certain other payments to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.

Penalties

(1) Failure to Furnish Taxpayer Identification Number. If you fail to furnish your correct taxpayer identification number to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

(2) Civil Penalty for False Information with Respect to Withholding. If you make a false statement with no reasonable basis that results in no backup withholding, you are subject to a $500 penalty.

(3) Criminal Penalty for Falsifying Information. Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

(4) Misuse of Taxpayer Identification Number. If the requester discloses or uses a taxpayer identification number in violation of federal law, the requester may be subject to civil or criminal penalties.
