Item 6.  Indemnification of Officers and Directors.

         The Company's By-laws provide that the Company shall indemnify any
person made, or threatened to be made, a party to an action or proceeding,
whether civil or criminal or investigative (a "proceeding"), including an action
by or in the right of the Company or any other corporation of any type or kind,
domestic or foreign, or any partnership, joint venture, trust, employee benefit
plan or other enterprise, which any director or officer of the Company served in
any capacity at the request of the Company, by reason of the fact that he, his
testator or interstate, was a director or officer of the Company, or served such
other corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise in any capacity, against judgment, fines, amounts paid in
settlement and reasonable expenses, including attorney's fees actually and
necessarily incurred as a result of such proceeding, or any appeal therein, if
such director or officer acted, in good faith, for a purpose which he reasonably
believed to be in, or in the case of service for any other corporation or any
partnership, joint venture, trust, employee benefit plan or other enterprise,
not opposed to, the best interests of the Company and, in criminal proceedings,
in addition, had no reasonable cause to believe that his conduct was unlawful.

         Any determination as to whether a person has met an applicable standard
of conduct shall be made in accordance with the provisions of the Business
Corporation Law of the State of New York.

         No indemnification shall be made to or on behalf of any person if a
judgment or other final adjudication adverse to such person establishes that his
acts were committed in bad faith or were the result of active and deliberate
dishonesty and were material to the cause of action so adjudicated, or that he
personally gained in fact a financial profit or other advantage to which he was
not legally entitled.






                                       4

        4.1            Consulting Agreement between CECO Environmental Corp. and

Item 9.  Undertakings.

(1)      The undersigned Registrant hereby undertakes:

             (a) To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement: To include any
material information with respect to the plan of distribution not previously
disclosed in the Registration Statement or any material change to such
information in the Registration Statement;

             (b) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof;

             (c) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

(2)          The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the Registration
Statement shall be deemed to be a new registration statement relating to the
securities offered therein and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

(2)          Insofar as indemnification for liabilities arising under the
         Securities Act of 1933 may be permitted to directors, officers and
         controlling persons of the Registrant pursuant to the foregoing
         provisions, or otherwise, the Registrant has been advised that in the 
         opinion of the Securities and Exchange Commission such indemnification
         is against public policy as expressed in the Act and is, therefore,
         unenforceable. In the event that a claim for indemnification against
         such liabilities (other than the payment by the Registrant of expenses
         incurred or paid by a director, officer or controlling person of the
         Registrant in the successful defense of any action, suit or proceeding)
         is asserted by such director, officer or controlling person in
         connection with the securities being registered, the Registrant will,
         unless in the opinion of its counsel the matter has been settled by
         controlling precedent, submit to a court of appropriate jurisdiction 
         the question whether such indemnification by it is against public 
         policy as expressed in the Act and will be governed by the final
         adjudication of such issue.

between CECO Environmental Corp., a New York corporation (the "Company"), and
IRG Investors Relations Group Ltd. (hereinafter referred to as a "Holder" or
"IRG").
                              W I T N E S S E T H :
                              - - - - - - - - - - 

         WHEREAS, IRG provides public relations services to public companies; 
and
         WHEREAS, IRG has agreed to provide public relations services to the
Company and the Company has agreed to engage IRG to provide public relations
services;

         WHEREAS, the Company desires to grant to IRG, and IRG desires to accept
from the Company, warrant certificates giving IRG the right to purchase shares
of the Company's Common Stock.

         NOW, THEREFORE, in consideration of the premises contained herein, the
payment by IRG to the Company of an aggregate of ten dollars ($10.00), the
agreements herein set forth and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

         1. Grant. IRG is granted the right to purchase, from the Company, at
any time from November 2, 1998, until 5:30 p.m., New York time, on November 2,
2000 (the "Expiration Date"), at which time the Warrants expire, up to an
aggregate of 250,000 shares (subject to adjustment as provided in Section 11
hereof) of common stock, par value $.01 per share, of the Company ("Common
Stock") at an initial exercise price (subject to adjustment as provided in
Section 11 hereof) of $2.00 per share and up to an aggregate of 250,000 shares
(subject to adjustment as provided in Section 11 hereof) of common stock, par
value $.01 per share, of the Company ("Common Stock") at an initial exercise
price (subject to adjustment as provided in Section 11 hereof) of $3.00 per
share (both the $2.00 per share exercise price and the $3.00 per share exercise
price shall be referred to herein as the "Exercise Price").










                                       14
<PAGE>


         2. Warrant Certificates. The warrant certificates (the "Warrant
Certificates") delivered and to be delivered pursuant to this Agreement shall be
in the forms set forth in Exhibits A and B, attached hereto and made a part
hereof, with such appropriate insertions, omissions, substitutions, and other
variations as required or permitted by this Agreement.

         3. Registration of Warrant. The Warrants shall be numbered and shall
be registered on the books of the Company when issued.

         4. Exercise of Warrant.

             4.1 Method of Exercise. The Warrants initially are exercisable
at the product of (i) the Exercise Price multiplied by (ii) the number of shares
of Common Stock purchased (subject to adjustment as provided in Section 11
hereof), as set forth in Section 8 hereof payable by certified or official bank
check in United States dollars. The product of the number of Warrants exercised
at any one time multiplied by the Exercise Price shall be referred to as the
"Purchase Price." Upon surrender of a Warrant Certificate with the annexed Form
of Election to Purchase duly executed, together with payment of the Purchase
Price for the shares of Common Stock purchased at the Company's principal
offices located at 505 University Avenue, Suite 1400, Toronto, Ontario, Canada,
the registered holder of a Warrant Certificate ("Holder" or "Holders") shall be
entitled to receive a certificate or certificates for the shares of Common Stock
so purchased. The purchase rights represented by each Warrant Certificate are
exercisable at the option of the Holder thereof, in whole or in part (but not as
to fractional shares of the Common Stock). In the case of the purchase of less
than all the shares of Common Stock purchasable under any Warrant Certificate,
the Company shall cancel said Warrant Certificate upon the surrender thereof and
shall execute and deliver a new Warrant Certificate of like tenor for the
balance of the shares of Common Stock purchasable thereunder.







                                       15
<PAGE>



         5. Issuance of Certificates. Upon the exercise of the Warrants, the
issuance of certificates for shares of Common Stock shall be made forthwith (and
in any event within five (5) business days thereafter) without charge to the
Holder thereof including, without limitation, any tax which may be payable in
respect of the issuance thereof, and such certificates shall (subject to the
provisions of Sections 7 and 9 hereof) be issued in the name of, or in such
names as may be directed by, the Holder thereof; provided, however, that the
Company shall not be required to pay any tax which may be payable in respect of
any transfer involved in the issuance and delivery of any such certificates in a
name other than that of the Holder and the Company shall not be required to
issue or deliver such certificates unless or until the person or persons
requesting the issuance thereof shall have paid to the Company the amount of
such tax or shall have established to the satisfaction of the Company that such
tax has been paid.

         The Warrant Certificates and the certificates representing the shares
of Common Stock, or other securities, property or rights issued upon exercise of
the Warrants shall be executed on behalf of the Company by the manual or
facsimile signature of the then present President or any Vice President of the
Company under its corporate seal reproduced thereon, attested to by the manual
or facsimile signature of the then present Secretary or any Assistant Secretary
of the Company. Warrant Certificates shall be dated the date of execution by the
Company upon initial issuance, division, exchange, substitution or transfer.

         6. Transfer of Warrant. The Warrants shall be transferable only on the
books of the Company maintained at its principal office, where its principal
office may then be located, upon delivery thereof duly endorsed by the Holder or
by its duly authorized attorney or representative accompanied by proper evidence
of succession, assignment or authority to transfer. Upon any





                                       16
<PAGE>



registration transfer, the Company shall execute and deliver new Warrants to the
person entitled thereto.

         7. Restriction On Transfer of Warrants. The Holder of a Warrant
Certificate, by its acceptance thereof, covenants and agrees that the Warrants
are being acquired as an investment and not with a view to the distribution
thereof.

         8. Exercise Price and Number of Securities. Except as otherwise
provided in Section 10 hereof, each of the Warrants are exercisable to purchase
one share of Common Stock at an initial exercise price equal to the applicable
Exercise Price. The Exercise Price and the number of shares of Common Stock for
which the Warrant may be exercised shall be the price and the number of shares
of Common Stock which shall result from time to time from any and all
adjustments in accordance with the provisions of Section 11 hereof.

         9.       Registration Rights.

                  9.1 Registration Under the Securities Act of 1933. Each
Warrant Certificate and each certificate representing the shares of Common
Stock, and any of the other securities issuable upon exercise of the Warrants
and the securities underlying the securities issuable upon exercise of the
Warrants (collectively, the "Warrant Shares") shall bear the following legend,
unless (i) such Warrants or Warrant Shares are distributed to the public or sold
for distribution to the public pursuant to this Section 9 or otherwise pursuant
to a registration statement filed under the Securities Act of 1933, as amended
(the "Act"), (ii) such Warrants or Warrant Shares are subject to a currently
effective registration statement under the Act; or (iii) the Company has
received an opinion of counsel, in form and substance reasonably satisfactory to
counsel for the Company, that such legend is unnecessary for any such
certificate:

         THE WARRANTS REPRESENTED BY THIS CERTIFICATE AND THE OTHER SECURITIES
         ISSUABLE UPON EXERCISE THEREOF MAY NOT BE OFFERED OR SOLD EXCEPT
         PURSUANT TO (i) AN EFFECTIVE REGISTRATION STATEMENT




                                       17
<PAGE>



         UNDER THE SECURITIES ACT OF 1933, (ii) TO THE EXTENT APPLICABLE, RULE
         144 UNDER SUCH ACT (OR ANY SIMILAR RULE UNDER SUCH ACT RELATING TO THE
         DISPOSITION OF SECURITIES), OR (iii) AN OPINION OF COUNSEL, IF SUCH
         OPINION SHALL BE REASONABLY SATISFACTORY TO COUNSEL FOR THE ISSUER,
         THAT AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS AVAILABLE.

         THE TRANSFER OR EXCHANGE OF THE WARRANTS OR OTHER SECURITIES
         REPRESENTED BY THE CERTIFICATE IS RESTRICTED IN ACCORDANCE WITH THE
         WARRANT AGREEMENT REFERRED TO HEREIN.


                  9.2 Piggyback Registration. If, at any time commencing
November 2, 1998, and expiring on the Expiration Date, the Company proposes to
register any of its securities, not registered on the date hereof, under the Act
(other than in connection with a merger or pursuant to Form S-4 or Form S-8,
unless Form S-8 can be used to register the Warrant Shares) it will give written
notice by registered mail, at least thirty (30) days prior to the filing of each
such registration statement, to the Holders of the Warrants and/or the Warrant
Shares of its intention to do so. If any of the Holders of the Warrants and/or
Warrant Shares notify the Company within twenty (20) days after mailing of any
such notice of its or their desire to include any such securities in such
proposed registration statement, the Company shall afford such Holders of the
Warrants and/or Warrant Shares the opportunity to have any such Warrant Shares
registered under such registration statement. In the event that the managing
underwriter, if any, for said offering advises the Company in writing that in
the underwriter's opinion the number of securities requested to be included in
such registration exceeds the number which can be sold in such offering without
causing a diminution in the offering price or otherwise adversely affecting the
offering, the Company will include in such registration (a) first, the
securities the Company proposes to sell, (b) second, the securities held by the
entities that made the demand for registration, (c) third, the Warrants and/or
Warrant Shares requested to be included in such registration which in the
opinion of such underwriter can be sold, pro rata among the Holders of Warrants
and/or Warrant Shares on the basis of the number of Warrants and/or Warrant
Shares requested to be registered by such Holders, and (d) fourth, other
securities requested to be included in such registration.

         Notwithstanding the provisions of this Section 9.2, the Company shall
have the right at any time after it shall have given written notice pursuant to
this Section 9.2 (irrespective of whether a written request for inclusion of any
such securities shall have been made) to elect not to file any such proposed
registration statement or to withdraw the same after the filing but prior to the
effective date thereof.

                  9.3      Demand Registration.

                           (a) At any time commencing November 2, 1998 and
expiring on the Expiration Date, the Holders of the Warrants and/or Warrant
Shares representing a "Majority" (as hereinafter defined) of the Warrants and/or
Warrant Shares shall have the right on two occasions (which right is in addition
to the registration rights under Section 9.2 hereof), exercisable by written 
notice to the Company, to have the Company prepare and file with the Securities
and Exchange Commission (the "Commission"), a registration statement and such 
other documents, including a prospectus, as may be necessary in the opinion of
both counsel for the Company and counsel for the Holders, in order to comply
with the provisions of the Act, so as to permit the public sale by such Holders
and any other Holders of the Warrants and/or Warrant Shares who notify the
Company within fifteen (15) days after the Company mails notice of such request
pursuant to Section 9.3(b) hereof (collectively, the "Requesting Holders") of
their respective Warrant Shares so as to allow the unrestricted sale of the
Warrant Shares to the public from time to time until the earlier of the
following: (i) the Expiration Date, (ii) the date on which all of the Warrant
Shares requested to be registered by the Requesting Holders have been sold (the
"Registration Period") or (iii) the date on which such Warrant Shares can be 
sold without registration pursuant to Rule 144 under the Act or an equivalent
exemption.

                           (b) The Company covenants and agrees to give written
notice of any registration request under this Section 9.3 by any Holder or 
Holders



                                       19
<PAGE>





representing a Majority of the Warrants and/or Warrant Shares to all 
other registered Holders of the Warrants and the Warrant Shares within ten (10)
days from the date of the receipt of any such registration request.

registration statement within ninety (90) days of receipt of any demand
therefor, and to have any registration statements declared effective at the
earliest possible time, and shall furnish each Holder desiring to sell Warrant

shall also file such applications and other documents as may be necessary to
permit the sale of the Warrant Shares to the public during the Registration
Period in those states to which the Company and the holders of the Warrants
and/or Warrant Shares shall mutually agree.

                           (b) The Company shall pay all costs (excluding fees
and expenses of Holder(s)' counsel and any underwriting
or selling commissions), fees and expenses in connection with all registration
statements filed pursuant to Sections 9.2 and 9.3(a) hereof including, without
limitation, the Company's legal and accounting fees, printing expenses, blue sky
fees and expenses. The Holder(s) will pay all costs, fees and expenses in
connection with the registration statement filed pursuant to Section 9.3(c).

                           (c) The Company will take all necessary action which
may be required in qualifying or registering the Warrant Shares included in a
registration statement for offering and sale under the securities or blue sky
laws of such states as reasonably are requested by the Holder(s), provided that
the Company shall not be obligated to execute or file any general consent to
service of process or to qualify as a foreign corporation to do business under
the laws of any such jurisdiction.

                           (d) The Company shall indemnify the Holder(s) of the
Warrant Shares to be sold pursuant to any registration statement and each
person, if any, who controls such Holder(s) within the meaning of Section 15 of
the Act or Section 20(a) of the Securities Exchange Act of 1934, as amended
("Exchange Act"), against all loss, claim, damage, expense or liability
(including all expenses reasonably incurred in investigating, preparing or
defending against any claim whatsoever) to which any of them may become subject
under the Act, the Exchange Act or otherwise, arising from such registration
statement.

                           (e) In order to provide for just and equitable
contribution under the Act in any case in which (i) any Holder of the Warrant
Shares or controlling person thereof makes a claim for indemnification but it is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that the express provisions of Section 9.4(d) hereof
provide for indemnification in such case or (ii) contribution under the Act may
be required on the part of any Holder of the Warrant Shares, or controlling
person thereof, then the Company, any such Holder of the Warrant Shares, or
controlling person thereof shall contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (which shall, for all
purposes of this Agreement, include, but not be limited to, all costs of defense
and investigation and all attorneys fees), in either such case (after
contribution from others) on the basis of relative fault as well as any other
relevant equitable considerations. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand or a Holder of
Warrant Shares, or controlling person thereof on the other and the





                                       21
<PAGE>



parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Company and such Holders of
such securities and such controlling persons agree that it would not be just and
equitable if contribution pursuant to this Section 9.4(e) were determined by pro
rata allocation or by any other method which does not take account of the
equitable considerations referred to in this Section 9.4(e). The amount paid or 
payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to above in this Section 
9.4(e) shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. No person guilty of fraudulent misrepresentation 
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                           (f) The Holder(s) of the Warrant Shares to be sold
pursuant to a registration statement, and their successors and assigns, shall
severally, and not jointly, indemnify the Company, its officers and directors
and each person, if any, who controls the Company within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act, against any loss, claim,
damage or expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which
they may become subject under the Act, the Exchange Act or otherwise, arising
from information furnished in writing, by or on behalf of such Holders, or their
successors or assigns, for specific inclusion in such registration statement.

                           (g) Nothing contained in this Agreement shall be
construed as requiring the Holder(s) to exercise their Warrants prior to the
initial filing of any registration statement or the effectiveness thereof.

                           (h) The Company shall furnish to each Holder
participating in the offering and to each underwriter, if any, a signed
counterpart, addressed to such Holder or underwriter, of (i) an opinion of
counsel to the Company, dated the effective date of such registration statement
(and, if such registration includes an underwritten public offering, an opinion
dated the date of the closing under the underwriting agreement), and (ii) a
"cold comfort" letter dated the effective date of such registration statement
(and, if such registration includes an underwritten public offering, a "cold
comfort" letter dated the date of the closing under the underwriting agreement)
signed by the independent public accountants who have issued a report on the
Company's financial statements included in such registration statement, in each
case covering substantially the same matters with respect to such registration
statement (and the prospectus included therein) and, in the case of such
accountants' letter, with respect to events subsequent to the date of such
financial statements, as are customarily covered in opinions of issuer's counsel
and in accountants' letters delivered to underwriters in underwritten public
offerings of securities.

                           (i) The Company shall as soon as practicable after
the effective date of the registration statement, and in any event within 15
months thereafter, make "generally available to its security holders" (within
the meaning of Rule 158 under the Act) an earnings statement (which need not be
audited) complying with Section 11(a) of the Act and covering a period of at
least 12 consecutive months beginning after the effective date of the
registration statement.

                           (j) The Company shall enter into an underwriting
agreement with the managing underwriters selected for such underwriting by
Holders holding a Majority of the Warrant Shares requested to be included in
such underwriting. Such agreement shall be satisfactory in form and substance to
the Company, each Holder and such managing underwriters, and shall contain such






                                       23
<PAGE>



representations, warranties and covenants by the Company and such other terms as
are customarily contained in agreements of that type used by the managing
underwriter. The Holder(s) shall be parties to any underwriting agreement
relating to an underwritten sale of their Warrant Shares and may, at their
option, require that any or all of the representations, warranties and covenants
of the Company to or for the benefit of such underwriters shall also be made to
and for the benefit of such Holder(s). Such Holder(s) shall not be required to
make any representations or warranties to or agreements with the Company or the
underwriters except as they may relate to such Holder(s) and their intended
methods of distribution.

                           (k) For purposes of this Agreement, the term
"Majority" in reference to the Warrants or Warrant Shares, shall mean in excess
of fifty percent (50%) of the then outstanding Warrants or Warrant Shares that
(i) are not held by the Company, or (ii) have not been resold to the public
pursuant to a registration statement filed with the Commission under the Act or
Rule 144 promulgated under the Act, or similar exemption.

         10. Obligations of Holders. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Section 9 hereof that
each of the selling Holders shall:

                           (a) Furnish to the Company such information regarding
themselves, the Warrant Shares held by them, the intended method of sale or
other disposition of such securities, the identity of and compensation to be
paid to any underwriters proposed to be employed in connection with such sale or
other disposition, and such other information as may reasonably be required to
effect the registration of their Warrant Shares.

                           (b) Notify the Company, at any time when a prospectus
relating to the Warrant Shares covered by a registration statement is required
to be delivered under the Act, of the happening of any event with respect to
such selling Holder as a result of which the prospectus included in such




                                       24
<PAGE>



registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances then existing.

         11. Adjustments to Exercise Price and Number of Securities. The
Exercise Price in effect at any time and the number and kind of securities
purchasable upon the exercise of the Warrants or the securities underlying the
Warrants shall be subject to adjustment from time to time upon the happening of
certain events as follows:

                  11.1 Dividend, Subdivision and Combination. In case the
Company shall (i) declare a dividend or make a distribution on its outstanding
shares of Common Stock in shares of Common Stock, (ii) subdivide or reclassify
its outstanding shares of Common Stock into a greater number of shares, or (iii)
combine or reclassify its outstanding shares of Common Stock into a smaller
number of shares, the Exercise Price in effect at the time of the record date
for such dividend or distribution or of the effective date of such subdivision,
combination or reclassification shall be adjusted so that it shall equal the
price determined by multiplying the Exercise Price by a fraction, the
denominator of which shall be the number of shares of Common Stock outstanding
after giving effect to such action, and the numerator of which shall be the
number of shares of Common Stock outstanding immediately prior to such action.
Such adjustment shall be made successively whenever any event listed above shall
occur.
                  11.2 Adjustment in Number of Securities. Upon each adjustment
of the Exercise Price pursuant to the provisions of this Section 11, the number
of Warrant Shares issuable upon the exercise at the adjusted Exercise Price of
each Warrant shall be adjusted to the nearest number of whole shares of Common
Stock determined by multiplying a number equal to the Exercise Price in effect
immediately prior to such adjustment by the number of the applicable Warrant




                                       25
<PAGE>



Shares issuable upon exercise of the Warrants immediately prior to such
adjustment and dividing the product so Obtained by the adjusted Exercise Price.

                  11.3 Definition of Common Stock. For the purpose of this
Agreement, the term "Common Stock" shall mean (i) the class of stock designated
as Common Stock in the Articles of Incorporation of the Company as of the date
hereof, or (ii) any other class of stock resulting from successive changes or
reclassifications of such Common Stock consisting solely of changes in par
value, or from par value to no par value, or from no par value to par value.

                  11.4 Merger or Consolidation. In case of any consolidation of
the Company with, or merger of the Company into, another corporation (other than
a consolidation or merger which does not result in any reclassification or
change of the outstanding Common Stock), the corporation formed by such
consolidation or merger shall execute and deliver to each Holder a supplemental
warrant agreement providing that the Holder of each Warrant then outstanding
shall have the right thereafter (until the Expiration Date) to receive, upon
exercise of such Warrant, the kind and amount of shares of stock and other
securities and property receivable upon such consolidation or merger to which
the Holder would have been entitled if the Holder had exercised such Warrant
immediately prior to such consolidation, merger, sale or transfer. Such
supplemental warrant agreement shall provide for adjustments which shall be
identical to the adjustments provided in this Section 11. The above provision of
this subsection shall similarly apply to successive consolidations or mergers.

                  11.5 No Adjustment of the Exercise Price in Certain Cases. No
adjustment of the Exercise Price shall be made:

                           (a)  Upon the issuance or sale of the Warrants or the
Warrant Shares;

                           (b) Upon the issuance or sale of Common Stock (or any
other security convertible, exercisable, or exchangeable into shares of Common
Stock)



                                       26
<PAGE>


upon the direct or indirect conversion, exercise, or exchange of any options,
rights, warrants, or other securities or indebtedness of the Company outstanding
as of the date of this Agreement or granted pursuant to any stock option plan of
the Company in existence as of the date of this Agreement, pursuant to the terms
thereof or issued pursuant to any stock purchase plan in existence as of the
date of this Agreement, pursuant to the terms thereof; or

                           (c) If the amount of said adjustment shall be less
than ten cents ($.10) per share, provided, however, that in such case any
adjustment that would otherwise be required then to be made shall be carried
forward and shall be made at the time of and together with the next subsequent
adjustment which, together with any adjustment so carried forward, shall amount
to at least ten cents ($.10) per share.

         12. Exchange and Replacement of Warrant Certificates. Each Warrant
Certificate is exchangeable, without expense, upon the surrender thereof by the
registered Holder at the principal executive office of the Company for a new
Warrant Certificate of like tenor and date representing in the aggregate the
Holder's right to purchase the same number of Warrant Shares in such
denominations as shall be designated in such Warrant Certificate at the time of
such surrender.

         Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of any Warrant Certificate, and,
in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrant
Certificate, if mutilated, the Company will make and deliver a new Warrant
Certificate of like tenor, in lieu thereof.

         13. Elimination of Fractional Interests. The Company shall not be
required to issue certificates representing fractions of shares of Common Stock
or other securities upon the exercise of the Warrants, nor shall it be required





                                       27
<PAGE>

to issue scrip or pay cash in lieu of fractional interests, it being the intent
of the parties that all fractional interests shall be eliminated by rounding any
fraction up to the nearest whole number of shares of Common Stock or other
securities, properties or rights.

         14. Reservation and Listing of Securities. The Company shall at all
times reserve and keep available out of its authorized shares of Common Stock,
solely for the purpose of issuance upon the exercise of the Warrants, such
number of shares of Common Stock or other securities, properties or rights as
shall be issuable upon the exercise thereof or the exercise or conversion of any
other exercisable or convertible securities underlying the Warrants. Every
transfer agent and warrant agent (collectively "Transfer Agent") for the Common
Stock and other securities of the Company issuable upon the exercise of the
Warrants will be irrevocably authorized and directed at all times to reserve
such number of authorized shares of Common Stock and other securities as shall
be requisite for such purpose. The Company will keep a copy of this Agreement on
file with every Transfer Agent for the Common Stock and other securities of the
Company issuable upon the exercise of the Warrants. The Company will supply
every such Transfer Agent with duly executed stock and other certificates, as
appropriate, for such purpose. The Company covenants and agrees that, upon each
exercise of the Warrants and payment of the Purchase Price, all shares of Common
Stock and other securities issuable upon such exercise shall be duly and validly
issued, fully paid, non-assessable and not subject to the preemptive rights of
any stockholder. As long as the Warrants shall be outstanding, the Company shall
use its best efforts to cause all shares of Common Stock and other securities
issuable upon the exercise of the Warrants and the securities underlying the
securities issuable upon exercise of the Warrants to be listed (subject to
official notice of issuance) on all securities exchanges or securities
associations on which the Common Stock issued to the public in connection
herewith may then be listed and/or quoted.

         15. Notices to Warrant Holders. Nothing contained in this Agreement
shall be construed as conferring upon the Holder(s) of the Warrants the right to
vote or to consent or to receive notice as a stockholder in respect of any
meetings of stockholders for the election of directors or any other matter, or
as having any rights whatsoever as a stockholder of the Company. If, however, at
any time prior to the expiration of the Warrants and their exercise, any of the
following events shall occur:

                           (a) the Company shall take a record of the holders of
its shares of Common Stock for the purpose of entitling them to receive a
dividend or distribution payable otherwise than in cash, or a cash dividend or
distribution payable otherwise than out of current or retained earnings, as
indicated by the accounting treatment of such dividend or distribution on the
books of the Company; or

                           (b) the Company shall offer to all the holders of its
Common Stock any additional shares of capital stock of the Company or securities
convertible into or exchangeable for shares of capital stock of the Company, or
any option, right or warrant to subscribe therefor; or

                           (c) a dissolution, liquidation or winding up of the
Company (other than in connection with a consolidation or merger) or a sale of
all or substantially all of its property, assets and business as an entirety
shall be proposed; then in any one or more of said events, the Company shall
give written notice to the registered holders of the Warrants of such event at
least fifteen (15) days prior to the date fixed as a record date or the date of
closing the transfer books for the determination of the stockholders entitled to
such dividend, distribution, convertible or exchangeable securities or
subscription rights, or entitled to vote on such proposed dissolution,
liquidation, winding up or sale. Such notice shall specify such record date or
the date of closing the transfer books, as the case may be. Failure to give such
notice or any defect therein shall not affect the validity of any action





                                       29
<PAGE>

taken in connection with the declaration or payment of any such dividend, or the
issuance of any convertible or exchangeable securities, or subscription rights,
options or warrants, or any proposed dissolution, liquidation, winding up or
sale.

         16. Notices. All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed to have been duly made and
sent when delivered, or mailed by registered or certified mail, return receipt
requested:

                           (a) if to the registered Holder of the Warrants, to
the address of such Holder as shown on the books of the Company; or 

                           (b) if to the Company, to the address set forth in
Section 4 hereof or to such other address as the Company may designate by notice
to the Holders.

         17. Supplements; Amendments; Entire Agreement. This Agreement contains
the entire understanding between the parties hereto with respect to the subject
matter hereof and may not be modified or amended except by a writing duly signed
by the party against whom enforcement of the modification or amendment is
sought. The Company and IRG may from time to time supplement or amend this
Agreement without the approval of any Holders of Warrant Certificates (other
than IRG) in order to cure any ambiguity, to correct or supplement any provision
contained herein which may be defective or inconsistent with any provisions
herein, or to make any other provisions in regard to matters or questions
arising hereunder which the Company and IRG may deem necessary or desirable and
which the Company and IRG deem shall not adversely affect the interests of the
Holders of Warrant Certificates.

         18. Successors. All of the covenants and provisions of this Agreement
shall be binding upon and inure to the benefit of the Company, the Holder(s) and
their respective successors and assigns hereunder.

         19. Survival of Representations and Warranties. All statements in any
schedule, exhibit or certificate or other instrument delivered by or on behalf
of the parties hereto, or in connection with the transactions contemplated by
this Agreement, shall be deemed to be representations and warranties hereunder.
Notwithstanding any investigations made by or on behalf of the parties to this
Agreement, all representations, warranties and agreements made by the parties to
this Agreement or pursuant hereto shall survive.

         20. Governing Law; Submission to Jurisdiction. This Agreement and each
Warrant Certificate issued hereunder shall be deemed to be a contract made under
the laws of the State of New York and for all purposes shall be construed in
accordance with the laws of said State without giving effect to the rules of
said State governing the conflicts of laws.

         21. Severability. If any provision of this Agreement shall be held to
be invalid or unenforceable, such invalidity or unenforceability shall not
affect any other provision of this Agreement.

         22. Captions. The caption headings of the Sections of this Agreement
are for convenience of reference only and are not intended, nor should they be
construed as, a part of this Agreement and shall be given no substantive effect.

         23. Benefits of this Agreement. Nothing in this Agreement shall be
construed to give to any person or corporation other than the Company and IRG
and any other registered Holder(s) of the Warrant Certificates or Warrant Shares
any legal or equitable right, remedy or claim under this Agreement; and this
Agreement shall be for the sole and exclusive benefit of the Company and IRG and
any other Holder(s) of the Warrant Certificates or Warrant Shares.

         24. Counterparts. This Agreement may be executed in any number of
counterparts and each of such counterparts shall for all purposes be deemed to
be an original, and such counterparts shall together constitute but one and the
same instrument.

duly executed, as of the day and year first above written.

                               WARRANT CERTIFICATE

         This Warrant Certificate certifies that ___________________________, or
registered assigns, is the registered holder of Warrants to purchase initially,
at any time from November 2, 1998 until 5:30 p.m., New York time, on November 2,
2000 ("Expiration Date"), up to _____________ shares, of fully-paid and
non-assessable common stock, $.01 par value ("Common Stock") of CECO
Environmental Corp., a New York corporation (the "Company"), at the initial
exercise price, subject to adjustment in certain events, of $2.00 per share upon
surrender of this Warrant Certificate and payment of the Exercise Price at the
principal executive office of the Company, but subject to the conditions set
forth herein. Payment of the Exercise Price shall be made by certified or
official bank check in United States dollars payable to the order of the
Company.

         No Warrant may be exercised after 5:30 p.m., New York time, on the
Expiration Date, at which time all Warrants evidenced hereby, unless exercised
prior thereto, shall thereafter expire and shall be void.

         The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants issued pursuant to the Warrant Agreement, which
Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to for a description of the rights, limitation
of rights, obligations, duties and immunities thereunder of the Company and the
holders (the words "holders" or "holder" meaning the registered holders or
registered holder) of the Warrants.
                                     
         The Warrant Agreement provides that upon the occurrence of certain
events the Exercise Price and the type and/or number of the Company's securities
issuable thereupon may, subject to certain conditions, be adjusted. In such
event, the Company will, at the request of the holder, issue a new Warrant
Certificate evidencing the adjustment in the Exercise Price and the number
and/or type of securities issuable upon the exercise of the Warrants; provided,
however, that the failure of the Company to issue such new Warrant Certificates
shall not in any way change, alter, or otherwise impair, the rights of the
holder as set forth in the Warrant Agreement.

         Upon due presentment for registration of transfer of this Warrant
Certificate at the principal executive office of the Company, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued to the transferee(s) in
exchange for this Warrant Certificate, subject to the limitations provided
herein and in the Warrant Agreement, without any charge except for any tax or
other governmental charge imposed in connection with such transfer.

         Upon the exercise of less than all of the Warrants evidenced by this
Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such numbered of unexercised Warrants.

         The Company may deem and treat the registered holder(s) hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, and of any distribution to the holder(s) hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

         All terms used in this Warrant Certificate which are defined in the
Warrant Agreement shall have the meanings assigned to them in the Warrant
Agreement.

         This Warrant Certificate does not entitle any Warrant holder to any of
the rights of a shareholder of the Company.


         IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to
be duly executed under its corporate seal.

                               WARRANT CERTIFICATE

         This Warrant Certificate certifies that ___________________________, or
registered assigns, is the registered holder of Warrants to purchase initially,
at any time from November 2, 1998 until 5:30 p.m., New York time, on November 2,
2000 ("Expiration Date"), up to ____________ shares, of fully-paid and
non-assessable common stock, $.01 par value ("Common Stock") of CECO
Environmental Corp., a New York corporation (the "Company"), at the initial
exercise price, subject to adjustment in certain events, of $3.00 per share upon
surrender of this Warrant Certificate and payment of the Exercise Price at the
principal executive office of the Company, but subject to the conditions set
forth herein. Payment of the Exercise Price shall be made by certified or
official bank check in United States dollars payable to the order of the
Company.

         No Warrant may be exercised after 5:30 p.m., New York time, on the
Expiration Date, at which time all Warrants evidenced hereby, unless exercised
prior thereto, shall thereafter expire and shall be void.

         The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants issued pursuant to the Warrant Agreement, which
Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to for a description of the rights, limitation
of rights, obligations, duties and immunities thereunder of the Company and the
holders (the words "holders" or "holder" meaning the registered holders or
registered holder) of the Warrants.

         The Warrant Agreement provides that upon the occurrence of certain
events the Exercise Price and the type and/or number of the Company's securities
issuable thereupon may, subject to certain conditions, be adjusted. In such
event, the Company will, at the request of the holder, issue a new Warrant
Certificate evidencing the adjustment in the Exercise Price and the number
and/or type of securities issuable upon the exercise of the Warrants; provided,
however, that the failure of the Company to issue such new Warrant Certificates
shall not in any way change, alter, or otherwise impair, the rights of the
holder as set forth in the Warrant Agreement.

         Upon due presentment for registration of transfer of this Warrant
Certificate at the principal executive office of the Company, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued to the transferee(s) in
exchange for this Warrant Certificate, subject to the limitations provided
herein and in the Warrant Agreement, without any charge except for any tax or
other governmental charge imposed in connection with such transfer.

         Upon the exercise of less than all of the Warrants evidenced by this
Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such numbered of unexercised Warrants.

         The Company may deem and treat the registered holder(s) hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, and of any distribution to the holder(s) hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

         All terms used in this Warrant Certificate which are defined in the
Warrant Agreement shall have the meanings assigned to them in the Warrant
Agreement.

         This Warrant Certificate does not entitle any Warrant holder to any of
the rights of a shareholder of the Company.


         IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to
be duly executed under its corporate seal.

                               Warrant No. 1RG - 2




                               WARRANT CERTIFICATE

         This Warrant Certificate certifies that IRG Investor Relations Group
Ltd., or registered assigns, is the registered holder of Warrants to purchase
initially, at any time from November 2, 1998, until 5:30 p.m., New York time, on
November 2, 2000 ("Expiration Date"), up to 500,000 shares, of fully-paid and
non-assessable common stock, $.01 par value ("Common Stock") of CECO
Environmental Corp., a New York corporation (the "Company"), at the initial
exercise price, subject to adjustment in certain events, of $3.00 per share upon
surrender of this Warrant Certificate and payment of the Exercise Price at the
principal executive office of the Company, but subject to the conditions set
forth herein. Payment of the Exercise Price shall be made by certified or
official bank check in United States dollars payable to the order of the
Company.

         No Warrant may be exercised after 5:30 p.m., New York time, on the
Expiration Date, at which time all Warrants evidenced hereby, unless exercised
prior thereto, shall thereafter expire and shall be void.

         The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants issued pursuant to the Warrant Agreement, which
Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to for a description of the rights, limitation
of rights, obligations, duties and immunities thereunder of the Company and the
holders (the words "holders" or "holder" meaning the registered holders or
registered holder) of the Warrants.

         The Warrant Agreement provides that upon the occurrence of certain
events the Exercise Price and the type and/or number of the Company's securities
issuable thereupon may, subject to certain conditions, be adjusted. In such
event, the Company will, at the request of the holder, issue a new Warrant
Certificate evidencing the adjustment in the Exercise Price and the number
and/or type of securities issuable upon the exercise of the Warrants; provided,
however, that the failure of the Company to issue such new Warrant Certificates
shall not in any way change, alter, or otherwise impair, the rights of the
holder as set forth in the Warrant Agreement.

         Upon due presentment for registration of transfer of this Warrant
Certificate at the principal executive office of the Company, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued to the transferee(s) in






                                       45

exchange for this Warrant Certificate, subject to the limitations provided
herein and in the Warrant Agreement, without any charge except for any tax or
other governmental charge imposed in connection with such transfer.

         Upon the exercise of less than all of the Warrants evidenced by this
Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such numbered of unexercised Warrants.

         The Company may deem and treat the registered holder(s) hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, and of any distribution to the holder(s) hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

         All terms used in this Warrant Certificate which are defined in the
Warrant Agreement shall have the meanings assigned to them in the Warrant
Agreement.

         This Warrant Certificate does not entitle any Warrant holder to any of
the rights of a shareholder of the Company.

         IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to
be duly executed under its corporate seal.

Dated as of November 2, 1998.

          OPINION OF COUNSEL REGARDING LEGALITY AND CONSENT OF COUNSEL

                  (LETTERHEAD OF SUGAR, FRIEDBERG & FELSENTHAL)

                                December 8, 1998

         Re:      CECO Environmental Corp. 1998 Consulting Agreement

Ladies and Gentlemen:

         We have acted as counsel to CECO Environmental Corp. (the "Company") in
connection with the registration with the Securities and Exchange Commission on
Form S-8 of shares of the Company's common stock, $0.01 par value (the
"Shares"), which will be issuable upon exercise of warrants issued under the
above-referenced Consulting Agreement (the "Plan"). In connection with that
registration, we have reviewed the proceedings of the Board of Directors of the
Company relating to the registration and proposed issuance of the common stock,
the Articles of Incorporation of the Company and all amendments thereto, the
Bylaws of the Company and all amendments thereto, and such other documents and
matters as we have deemed necessary to the rendering of the following opinion.

         Based upon that review, it is our opinion that the Shares, when issued
in conformance with the terms and conditions of the Plan, will be legally
issued, fully paid, and nonassessable.

         We do not find it necessary for the purposes of this opinion to cover,
and accordingly we express no opinion as to, the application of the securities
or blue sky laws of the various states as to the issuance and sale of the
Shares.

         We consent to the use of this opinion in the registration statement
filed with the Securities and Exchange Commission in connection with the
registration of the Shares and to the reference to our firm under the heading
"Interests of Named Experts and Counsel" in the registration statement.

                                                 Very truly yours,

                                                 SUGAR, FRIEDBERG & FELSENTHAL



                                            By   /s/ Leslie J. Weiss
