ITEM 5.  OTHER EVENTS.

         On December 31, 2001, CECO Environmental Corp. (the "Company")
completed the sale of 706,668 shares of its common stock, at a price of $3.00
per share, and the issuance of warrants ("Warrants") to purchase 353,334 shares
of its common stock, at an initial exercise price of $3.60 per share, to a group
of accredited investors, led by a Chicago-based private investment fund. The
gross proceeds to the Company from the equity investment was $2,120,000. CECO
paid the proceeds to its lenders to reduce outstanding indebtedness.

         There are certain provisions in the Subscription Agreement that
provides that if the Company's EBITDA for its 2002 fiscal year is less than
$7,800,000 (as determined in accordance with GAAP), then the Company will issue
a number of shares of Common Stock to each purchaser equal to 1.5% of the
initial number of shares of common stock issued to such purchaser for every
$100,000 under $7,800,000 that the Company's EBITDA is, which could result in an
additional issuance of 826,801 shares of common stock. However, the Company will
not issue in excess of 1,772,576 shares of its common stock to the purchasers in
this transaction unless shareholder approval for issuance in excess of 1,772,576
shares is obtained.

         The Company has agreed to prepare and file a proxy statement to obtain
such shareholder approval. Each of Phillip DeZwirek (a director and the CEO and
Chairman of the Company), IntroTech Investments, Inc. (an affiliate of Mr. Jason
DeZwirek, a director and the Secretary of the Company), Can-Med Technology, Inc.
d/b/a Green Diamond Oil Corp. (an affiliate of Mr. Phillip DeZwirek and Mr.
Jason DeZwirek), and Icarus Investment Corp. (an affiliate of Mr. Jason DeZwirek
and Mr. Phillip DeZwirek) and the purchasers of the shares has agreed to vote
their shares in favor of issuing in excess of the 1,772,576 shares in accordance
with the terms of the Subscription Agreement and Warrants.

                             SUBSCRIPTION AGREEMENT


                                December 31, 2001

Ceco Environmental Corp.
505 University Avenue
Suite 1400
Toronto, Ontario Canada
MSG 1X3

Gentlemen:

                                  SUBSCRIPTION

     The undersigned Purchasers (collectively, the "Purchasers") hereby offer
and agree to purchase the units (the "Units") comprised of shares of common
stock (the "Shares") and warrants to purchase Shares (the "Warrants") to be
issued by Ceco Environmental Corp., a New York corporation (the "Company") (the
"Offering"). The Purchasers shall submit their checks payable to "Ceco
Environmental Corp." for the Units subscribed for in accordance with Schedule A.

                           OFFERING AND SALE OF UNITS

     The purchase price of the Units offered by the Company has been determined
unilaterally by the Company and is not the result of arm's-length negotiations.
The Offering is being made for $2,000,000 to $3,000,000 of Units, at the
election of the Purchasers. The Company shall issue Warrants initially
exercisable for 1/2 Share for each Share issued at the time of the initial
issuance of Shares. All subscription amounts will be available immediately to
the Company.

     The Company shall have no obligation to issue in excess of 1,772,576 Shares
(such number being 19.9% of the outstanding shares of the Company prior to the
issuance of the Shares) to the Purchasers in the aggregate until shareholder
approval for the issuance of the Shares and the Shares issuable on exercise of
the Warrants ("Warrant Shares") in excess of 1,772,576 Shares is received in
accordance with NASD rules and regulations. If, prior to the filing of the
Schedule 14A described below, Introtech Investments, Inc. ("Introtech"), Can-Med
Technology, Inc. (d/b/a Green Diamond Oil Corp.) ("Green Diamond"), Icarus
Investment Corp. ("Icarus"), Phillip DeZwirek, Crestview Capital Fund, L.P.
("Crestview") and any five of the Purchasers who are purchasing Units in the
aggregate own stock entitling them to cast a majority of the votes necessary to
approve any shareholder actions, then the Company will: (a) promptly (but not
later than 45 days) following the notification of the ownership by such persons
of such Shares, prepare in proper form and file with the SEC an information
statement on Schedule 14C ("Information Statement") and circulate such statement
to the Company's shareholders. If the above referenced 10 shareholders of the
Company do not own more than 50% of the stock of the Company, then the Company
will no later than November 1, 2002, prepare in proper form and file with the
SEC a proxy statement on Schedule 14A (a "Proxy Statement") for use in
soliciting proxies for the approval by the shareholders of the Company, (b) duly
call, give notice of and convene a meeting of its shareholders, as soon as
practicable, but not later than 20 days after the Proxy Statement is cleared by
the SEC, for purposes of obtaining shareholder approval of such Shareholder
Proposal, and (c) have the Proxy Statement cleared by the SEC and obtain such
shareholder approval. The term "Shareholder Proposal" shall mean the proposal to
approve the issuance of Shares and Warrant Shares in excess of 1,772,576 shares
in the aggregate. The Company agrees that it shall recommend that the Company's
shareholders vote in favor of the Shareholder Proposal. Each of Phillip
DeZwirek, Green Diamond, Introtech, Icarus, and each of the Purchasers agrees to
vote in favor of such proposal at the shareholder meeting, or prior to the
circulation of the Information Statement, in a Written Consent executed by such
persons approving the Shareholder Proposal. Company agrees that it will not
issue any shares prior to the time that shareholder approval of the Shareholder
Proposal is obtained unless such purchasing shareholder agrees to vote in favor
of the Shareholder Proposal; provided, however, that this limitation shall not
apply to shares issued upon exercise of outstanding options or warrants or any
shares to be issued or on exercise of options issued under the Company's 1997
Stock Option Plan or 1999 Employee Stock Purchase Plan or up to an additional
250,000 shares regardless of to whom issued.

                                       1
<PAGE>

     If Company circulates an Information Statement as described above, then
Crestview shall be obligated to reimburse Company for one-half of the actual,
documented, out of pocket costs of preparing, filing and circulating the
Information Statement (including but not limited to SEC filing fees and
reasonable legal fees).

     This issuance of Units shall close as soon as possible (the "Closing
Date"), but not later than December 31, 2001.

     In the event that there is a limit on the number of Shares that may be
issued under Article IV or on exercise of a Warrant due to the fact that the
Company's shareholders have not yet approved the Shareholder Proposal, such
limit shall be applied to each Purchaser on a pro rata basis based on the number
of Units purchased by such Purchaser. Company shall issue any of such Shares as
soon as practicable following the approval of the Shareholder Proposal.

                                 PURCHASE PRICE

     The per Unit purchase price will be $3.00.

     The exercise price for each warrant issued hereunder shall be $3.60 per
Warrant Share. The exercise price shall be subject to adjustment as specified in
the Warrants.

                            ADDITIONAL SHARE ISSUANCE

     If the Company's EBITDA for its 2002 fiscal year is less than $7,800,000
(as determined in accordance with GAAP (except that adjustments to earnings
attributable to the issuance of the Warrants or any options/warrants issued to
The Shemano Group shall not be taken into account), without any "pro forma
adjustments" and as indicated on the Company's Form 10-K, including any
amendment thereto), then the Company shall issue a number of Shares to each
Purchaser equal to 1.5% of the initial number of Shares issued to such Purchaser
for every $100,000 under $7,800,000 that the Company's EBITDA is. For instance,
if the Company's EBITDA is $7,550,000 for fiscal 2002 and a Purchaser initially
received 100,000 Shares, then the Company would be required to issue an
additional 3750 Shares to such Purchaser at no additional cost to such
Purchaser.

                                       2
<PAGE>

     With respect to each Purchaser, if and whenever on or after the date of
this Agreement until the earlier to occur of: a) the date 2 years after the Form
S-1 described in Schedule B is determined effective by the SEC and b) the date
90% of the Shares received by any Purchaser on the Closing Date are no longer
held by such Purchaser, the Company issues, sells or grants shares of Common
Stock, or is deemed to have issued, sold or granted shares of Common Stock for
consideration per share less than the Purchase Price (the "Dilutive Price") in
effect immediately prior to the time of such issuance or sale (a "Dilutive
Event"), then forthwith upon the occurrence of any such Dilutive Event the
Purchase Price shall be reduced so that the Purchase Price in effect immediately
following the Dilutive Event will equal the Dilutive Price and: (a) the Company
shall within five (5) business days issue additional Shares to such Purchaser so
that such Purchaser will hold the same number of Shares it would have been
issued, solely with respect to Shares held on the date of the Dilutive Event,
had the Purchase Price in Article II equalled the Dilutive Price; provided,
however, that shares of Common Stock issued for consideration per share less
than the Conversion Price in connection with the following shall not be deemed a
Dilutive Event and will not trigger an adjustment to the Conversion Price as
provided in Article IV hereof: (i) the exercise of warrants and options
outstanding on the date of this Agreement, (ii) the issuance of options or
warrants or the receipt of Shares on exercise of such options or warrants with
respect to employees and officers of the Company or its subsidiaries pursuant to
the Company's 1997 Stock Option Plan or the 1999 Employee Stock Purchase Plan
(other than shares to be issued to Affiliates of the Company), (iii) the
issuance of warrants or options and the receipt of Stock on exercise of such
warrants or options with respect to directors of the Company and up to 250,000
options to be issued to consultants of the Company, (iv) reincorporation of the
Company in Delaware, (v) Warrants issued in connection with this Agreement; or
(vi) any acquisition, merger, bank financing or lending transaction approved by
the Company's Board of Directors provided that no party to such transaction is
an Affiliate of the Company. For purposes of this Agreement and the Warrants to
be issued hereunder, an "Affiliate" of the Company shall be a person who
controls, is controlled by or under common control with the Company.

     Issuance and Sale of Shares of Common Stock. For purposes of determining
the adjusted Purchase Price pursuant to Section IV(2) above, the following
events shall be deemed to be an issuance and sale of shares of Common Stock by
the Company:

          (a) Issuance of Rights or Options. If (i) the Company, in any manner,
     hereafter grants any rights or options to subscribe for, or to purchase,
     shares of Common Stock, or any securities convertible into or exchangeable
     for any shares of Common Stock (such rights or options referred to herein
     as "Options" and such convertible or exchangeable securities referred to
     herein as "Convertible Securities") and (ii) the price per share of Common
     Stock issuable upon the exercise of such Options or upon conversion or
     exchange of such Convertible Securities is less than the Purchase Price in
     effect immediately prior to the time of the granting of such Options, then
     the shares of Common Stock issuable upon the exercise of such Options or
     upon conversion or exchange of such Convertible Securities will be deemed
     to have been issued and sold by the Company for such lesser price per
     share. For the purposes of this Section IV(3)(a), the "price per share" is
     determined by dividing (i) the total amount, if any, received by the
     Company as consideration for the granting of such Options, plus the minimum
     aggregate amount of additional consideration payable to the Company upon
     exercise of all such Options, plus in the case of such Options which relate
     to Convertible Securities, the minimum aggregate amount of additional
     consideration, if any, payable to the Company upon the issuance or sale of
     such Convertible Securities and the conversion or exchange thereof by (ii)
     the total maximum number of shares of Common Stock issuable upon the
     exercise of such Options or upon the conversion or exchange of all such
     Convertible Securities issuable upon the exercise of such Options (without
     taking into account potential anti-dilution language in the terms of such).
     No further adjustment of the Conversion Price will be made when Convertible
     Securities are actually issued upon the exercise of such Options or when
     shares of Common Stock are actually issued upon the exercise of such
     Options or the conversion or exchange of such Convertible Securities.

                                       3
<PAGE>

          (b) Calculation of Consideration Received. If any shares of Common
     Stock, Options or Convertible Securities are issued or sold or deemed to
     have been issued or sold for cash, the consideration received therefor or
     the Price Per Share, as the case may be, will be deemed to be the net
     amount received or to be received, respectively, by the Company therefor.
     In case any Shares, Options or Convertible Securities are issued or sold
     for a consideration other than cash, the amount of the consideration other
     than cash received by the Company or the non-cash portion of the Price Per
     Share, as the case may be, will be the fair market value of such
     consideration received or to be received, respectively, by the Company. If
     any Shares, Options or Convertible Securities are issued in connection with
     any merger in which the Company is the surviving Company, the amount of
     consideration therefor will be deemed to be the fair value of such portion
     of the net assets and business of the non-surviving Company as is
     attributable to such Shares, Options or Convertible Securities, as the case
     may be. The fair value of any consideration other than cash and marketable
     securities will be determined by the Company.

          (c) Integrated Transactions. In case any Option is issued in
     connection with the issuance or sale of other securities of the Company,
     together comprising one integrated transaction in which no specific
     consideration is allocated to such Option by the parties thereto, the
     Option will be deemed to have been issued for a consideration of $.01.

     Additional Shares. Shares issuable under Section IV(1) or IV(2) are
referred to as "Additional Shares".

                                       4

           REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE PURCHASERS

     Each of the undersigned Purchasers, separately and not jointly, makes the
following additional agreements, representations, declarations, acknowledgments
and warranties with the intent that the same may be relied upon in determining
its suitability as a purchaser of Units:

     Such Purchaser agrees that; in the event his principal residence or its
principal place of business changes, he or it will promptly notify the Company.

     Such Purchaser is an "accredited investor" as defined in Regulation D.

     Such Purchaser has received, read, understands and is familiar with this
Subscription Agreement.

     The Units subscribed for herein by such Purchaser will be acquired solely
by and for the account of such Purchaser, for investment, and are not being
purchased for subdivision, fractionalization, resale or distribution, such
Purchaser has no contract, undertaking, agreement or arrangement with any person
to sell, transfer or pledge all or any part of the Units for which such
Purchaser hereby subscribes, and such Purchaser has no present plans or
intentions to enter into any such contract undertaking or arrangement. In order
to induce the Company to issue and sell the Units subscribed for hereby to such
Purchaser, the undersigned agrees that the Company will have no obligation to
recognize the ownership, beneficial or otherwise, of such Units by anyone but
such Purchaser.

     The undersigned acknowledges that he generally must hold the Units (and any
common stock issued on conversion of the Warrants) for a minimum period of one
year and may not sell, transfer, pledge or otherwise dispose of the Units
without registration under the Securities Act or the Laws unless an exemption
from registration is available. Further, such Purchaser shall provide, if the
Company so requires, an opinion of counsel, that the intended disposition will
not violate the Securities Act or the Laws or the rules and regulations of the
Securities and Exchange Commission or of any state securities commission
promulgated under such statutes.

     None of the Units, Shares nor Warrants have been registered under the
Securities Act and cannot be sold or transferred without compliance with the
registration provisions of said Securities Act or compliance with exemptions, if
any, available thereunder.

     Such Purchaser expressly represents that: (a) he has such knowledge and
experience in financial and business matters in general, and in investments in
shares of common stock and warrants, in particular, and that he is capable of
evaluating the merits, risks and other facets of the subject investment (b) his
financial condition is such that he has no need for liquidity with respect to
his investment in the Units to satisfy any existing or contemplated undertaking
or indebtedness; (c) he is able to bear the economic risk of his investment in
the Units for an indefinite period of time, including the risk of losing all of
his investment; (d) he has either secured independent tax advice with respect to
his investment in the Units, upon which he is relying, or he is sufficiently
familiar with the income taxation of corporations that he deemed such
independent advice to be unnecessary; (e) he has participated in other privately
placed investments and/or he has such knowledge and experience in business and
financial matters, has the capacity to protect his own interest in investments
like the subject investment, and is capable of evaluating the risks, merits and
other facets of the subject investment.

                                       5
<PAGE>

     Such Purchaser was not induced to invest by any form of general
solicitation or general advertising including, but not limited to, the
following: (i) any advertisement, article, notice or other communication
published in any newspaper, magazine or similar media or broadcast over the
television or radio; and (ii) any seminar or meeting whose attendees had been
invited by any general solicitation or general advertising.

     Purchaser has received and reviewed the Company's 2000 Form 10-KSB, the
latest proxy statement filed by the Company on Schedule 14A and the latest
quarterly report of the Company on Form 10-QSB (the "Offering Documents") and
the "Risk Factors" attached hereto. Such Purchaser expressly acknowledges that:
(a) the Units are a speculative investment that involve a high degree of risk of
loss of the entire investment of the undersigned in the Company; (b) no federal
or state agency has reviewed or passed upon the adequacy or accuracy of the
information set forth in the Offering Documents, or made any finding or
determination as to the fairness for investment, or any recommendation or
endorsement of the Units as an investment; (c) there will be no public market
for the Units and, accordingly, it may not be possible for the undersigned to
liquidate his investment in the Units; (d) the Units shall bear a legend
describing the restrictions on transfer; and (e) any anticipated federal and/or
state income tax benefits applicable to the Units may be lost through changes
in, or adverse interpretations of, existing laws and regulations. Such Purchaser
has relied only on such information contained in the Offering Documents and no
other information in determining whether to subscribe for Units.

     All information that such Purchaser has provided concerning himself and his
financial condition is correct and complete as of the date set forth on the
subscription page hereof, and if there should be any material change in such
information prior to the acceptance of his subscription for the Units that he is
purchasing, he will immediately provide such information to the Company.

     Such Purchaser acknowledges that an investment in the Company is risky and
that the undersigned has reviewed all of the risk factors set forth in the
Appendix hereto.

     If the Purchaser is an entity, the Purchaser is duly organized, validly
existing and in good standing under the laws of its state of organization. The
Purchaser has all necessary power and authority to own its properties and to
consummate the transactions contemplated by this Agreement; this Agreement has
been duly authorized, executed and delivered on behalf of the Purchaser, and is
the valid and binding obligation of the Purchaser, enforceable in accordance
with its terms, except (i) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting
enforcement of creditors' rights generally and (ii) as limited by laws relating
to the availability of specific performance, injunctive relief or other
equitable remedies; and the execution and performance of this Agreement by the

     Each Purchaser grants to Crestview an irrevocable power of attorney to make
such changes, as Crestview determines in its sole discretion, as are necessary

investigation made by or on behalf of such party on or prior to the Closing
Date.

     Indemnity. (a) The Company hereby agrees to indemnify and hold harmless the
Purchasers, their respective Affiliates and their respective officers,
directors, partners and members (collectively, the "Purchaser Indemnitees"),
from and against any and all Damages, and agrees to reimburse the Purchaser
Indemnitees for all reasonable out-of-pocket expenses (including the reasonable
fees and expenses of legal counsel), in each case promptly as incurred by the
Purchaser Indemnitees and to the extent arising out of or in connection with:

any misrepresentation, omission of fact or breach of any of the representations
or warranties contained in this Agreement or the annexes or by the Company,

                                       13
<PAGE>

     (b) Each Purchaser, severally and not jointly, hereby agrees to indemnify
and hold harmless the Company, its Affiliates and their respective officers,
directors, partners and members (collectively, the "Company Indemnitees"), from
and against any and all Damages, and agrees to reimburse the Company Indemnitees
for reasonable all out-of-pocket expenses (including the reasonable fees and
expenses of legal counsel), in each case promptly as incurred by the Company
Indemnitees and to the extent arising out of or in connection with any
misrepresentation, omission of fact, or breach of any of the Investor's

certificate entered into or delivered by the Investor pursuant to this
Agreement. Notwithstanding anything to the contrary herein, each Purchaser shall
be liable under this Section IX(2) for only that amount as does not exceed the
net proceeds to such Purchaser as a result of the sale of Shares.

     Notice. Promptly after receipt by either party hereto seeking
indemnification pursuant to Section IX(2) (an "Indemnified Party") of written
notice of any investigation, claim, proceeding or other action in respect of
notice of any investigation, claim, proceeding or other action in respect of
which indemnification is being sought (each, a "Claim"), the Indemnified Party
promptly shall notify the party from whom indemnification pursuant to Section
IX(2) is being sought (the "Indemnifying Party") of the commencement thereof;
but the omission so to notify the Indemnifying Party shall not relieve it from
any liability that it otherwise may have to the Indemnified Party, except to the
extent that the Indemnifying Party is actually prejudiced by such omission or
delay. In connection with any Claim as to which both the Indemnifying Party and
the Indemnified Party are parties, the Indemnifying Party shall be entitled to
assume the defense thereof. Notwithstanding the assumption of the defense of any
Claim by the Indemnifying Party, the Indemnified Party shall have the right to
employ separate legal counsel and to participate in the defense of such Claim,
and the Indemnifying Party shall bear the reasonable fees, out-of-pocket costs
and expenses of such separate legal counsel to the Indemnified Party if (and
only if): (x) the Indemnifying Party shall have agreed to pay such fees,
out-of-pocket costs and expenses, (y) the Indemnified Party reasonably shall
have concluded that representation of the Indemnified Party and the Indemnifying
Party by the same legal counsel would not be appropriate due to actual or, as
reasonably determined by legal counsel to the Indemnified Party, potentially
differing interests between such parties in the conduct of the defense of such
Claim, or if there may be legal defenses available to the Indemnified Party that
are in addition to or disparate from those available to the Indemnifying Party,
or (z) the Indemnifying Party shall have failed to employ legal counsel
reasonably satisfactory to the Indemnified Party within a reasonable period of
time after notice of the commencement of such Claim. If the Indemnified Party
employs separate legal counsel in circumstances other than as described in
clauses (x), (y) or (z) above, the fees, costs and expenses of such legal
counsel shall be borne exclusively by the Indemnified Party. Except as provided
above, the Indemnifying Party shall not, in connection with any Claim in the
same jurisdiction, be liable for the fees and expenses of more than one firm of
legal counsel for the Indemnified Party (together with appropriate local
counsel). The Indemnifying Party shall not, without the prior written consent of
the Indemnified Party (which consent shall not unreasonably be withheld), settle
or compromise any Claim or consent to the entry of any judgment that does not
include an unconditional release of the Indemnified Party from all liabilities
with respect to such Claim or judgment.

                                       14
<PAGE>

     All fees and expenses of the Indemnified Party (including reasonable costs
of defense and investigation in a manner not inconsistent with this section and,
except as otherwise provided above, all reasonable attorneys' fees and expenses)
shall be paid to the Indemnified Party, as incurred, within ten (10) trading
days of written notice thereof to the Indemnifying Party (regardless of whether
it is ultimately determined that an Indemnified Party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
such Indemnified Party to undertake to reimburse all such fees and expenses,
with interest at market rates, to the extent it is finally judicially determined
that such Indemnified Party is not entitled to indemnification hereunder).

     Direct Claims. In the event one party hereunder should have a claim for
indemnification that does not involve a claim or demand being asserted by a
third party, the Indemnified Party promptly shall deliver notice of such claim
to the Indemnifying Party. If the Indemnifying Party disputes the claim, such
dispute shall be resolved by mutual agreement of the Indemnified Party and the
Indemnifying Party or by binding arbitration conducted in accordance with the
procedures and rules of the American Arbitration Association. Judgment upon any
award rendered by any arbitrators may be entered in any court having competent
jurisdiction thereof.

                                  GOVERNING LAW

     This Agreement shall be governed by and construed and enforced in
accordance with the internal laws of the State of Illinois without regard to the
principles of conflicts of law thereof. Each party hereto hereby irrevocably
submits to the exclusive jurisdiction of the courts of the State of Illinois,
and of the United States of America sitting in the City of Chicago for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, that
the venue thereof may not be appropriate, that such suit, action or proceeding
is improper or that this Agreement or any of the documents referred to in this
Agreement may not be enforced in or by said courts, and each party hereto
irrevocably agrees that all claims with respect to such suit, action or
proceeding may be heard and determined in such an Illinois state or federal
court. Each party hereby irrevocably waives personal service of process and
consents to process being served in any such suit, action or proceeding by
mailing a copy thereof to such party and agrees that such service shall
constitute good and sufficient service of process and notice thereof. Nothing
contained herein shall be deemed to limit in any way right to serve process in
any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT
MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY
DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT OR
ANY TRANSACTION CONTEMPLATED HEREBY.

                                   Schedule B

         Registration of the Shares; Compliance with the Securities Act


     Registration Procedures and Expenses. The Company shall:


              (a) prepare and file with the SEC no later than 90 days after the
date first written above, a registration statement (a "Registration Statement")
on Form S-1 (or any successor form) to enable the resale of the Shares or
Warrant Shares by each Purchaser from time to time through public markets or in
privately-negotiated transactions;

              (b) use its best efforts, subject to receipt of necessary
information from the Purchaser, to cause the Registration Statement to become
effective within 150 days after the date hereof;

              (c) prepare and file with the SEC such amendments and supplements
to each Registration Statement and the Prospectus used in connection therewith
as may be necessary to keep such Registration Statement current and effective
for a period not exceeding the earlier of (i) the date on which each Purchaser
may sell all Shares then held by such Purchaser without restriction by the
volume limitations of Rule 144(k) of the Securities Act, (ii) 18 months after
the date such Registration Statement is declared effective by the SEC, or (iii)
such time as all Shares held by Purchasers have been sold pursuant to a
registration statement.

              (d) furnish to each Purchaser with respect to the Shares
registered under the Registration Statement such number of copies of the
Registration Statement, Prospectuses and Preliminary Prospectuses in conformity
with the requirements of the Securities Act and such other documents as each
Purchaser may reasonably request, in order to facilitate the public sale or
other disposition of all or any of the Shares by each Purchaser, provided,
however, that the obligation of the Company to deliver copies of Prospectuses or
Preliminary Prospectuses to each Purchaser shall be subject to the receipt by
the Company of reasonable assurances from the Purchaser that the Purchaser will
comply with the applicable provisions of the Securities Act and of such other
securities or blue sky laws as may be applicable in connection with any use of
such Prospectuses or Preliminary Prospectuses;

              (e) file documents required of the Company for normal blue sky
clearance in states specified in writing by the Purchasers;

              (f) bear all Company expenses in connection with the procedures in
paragraph (a) through (e) of this Section 1 and all of Purchasers' reasonable
legal fees (up to $25,000 for all Purchasers in the aggregate under this
Agreement and each of the Warrants) and the registration of the Shares pursuant
to the Registration Statement; and

              (g) advise each Purchaser, promptly after it shall receive notice
or obtain knowledge of the issuance of any stop order by the SEC delaying or
suspending the effectiveness of the Registration Statement or of the initiation
or threat of any proceeding for that purpose; and it will promptly use its
reasonable efforts to prevent the issuance of any stop order or to obtain its
withdrawal at the earliest possible moment if such stop order should be issued.

                                       24
<PAGE>

     The Company understands that each Purchaser disclaims being an underwriter,
but any Purchaser being deemed an underwriter by the SEC shall not relieve the
Company of any obligations it has hereunder.

     Transfer of Shares After Registration; Suspension.

              (a) Each Purchaser agrees that it will, except as contemplated in
the Registration Statement referred to in Section 1, promptly notify the Company
of any changes in the information set forth in the Registration Statement
regarding the Purchaser or its plan of distribution.

              (b) Except in the event that paragraph (c) below applies, the
Company shall (i) if deemed necessary by the Company, prepare and file from time
to time with the SEC a post-effective amendment to each Registration Statement
or a supplement to the related Prospectus or a supplement or amendment to any
document incorporated therein by reference or file any other required document
so that such Registration Statement will not contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, and so that, as
thereafter delivered to purchasers of the Shares being sold thereunder, such
Prospectus will not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading; (ii) provide the Purchaser copies of any documents filed
pursuant to Section 2(b)(i); and (iii) inform each Purchaser that the Company
has complied with its obligations in Section 2(b)(i) (or that, if the Company
has filed a post-effective amendment to the Registration Statement which has not
yet been declared effective, the Company will notify the Purchaser to that
effect, will use its reasonable efforts to secure the effectiveness of such
post-effective amendment as promptly as possible and will promptly notify the
Purchaser pursuant to Section 2(b)(i) hereof when the amendment has become
effective).

              (c) Subject to paragraph (d) below, in the event (i) of any
request by the SEC or any other federal or state governmental authority during
the period of effectiveness of each Registration Statement for amendments or
supplements to a Registration Statement or related Prospectus or for additional
information; (ii) of the issuance by the SEC or any other federal or state
governmental authority of any stop order suspending the effectiveness of a
Registration Statement or the initiation of any proceedings for that purpose;
(iii) of the receipt by the Company of any notification with respect to the
suspension of the qualification or exemption from qualification of any of the
Shares for sale in any jurisdiction or the initiation or threatening of any
proceeding for such purpose; or (iv) of any event or circumstance which, upon
the advice of its counsel, necessitates the making of any changes in such
Registration Statement or Prospectus, or any document incorporated or deemed to
be incorporated therein by reference, so that, in the case of the Registration
Statement, it will not contain any untrue statement of a material fact or any
omission to state a material fact required to be stated therein or necessary to
make the statements therein not misleading, and that in the case of the
Prospectus, it will not contain any untrue statement of a material fact or any
omission to state a material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; then the Company shall deliver a certificate in
writing to the Purchasers (the "Suspension Notice") to the effect of the
foregoing and, upon receipt of such Suspension Notice, the Purchasers will
refrain from selling any Shares pursuant to such Registration Statement (a
"Suspension") until the Purchaser's receipt of copies of a supplemented or
amended Prospectus prepared and filed by the Company, or until it is advised in
writing by the Company that the current Prospectus may be used, and has received
copies of any additional or supplemental filings that are incorporated or deemed
incorporated by reference in any such Prospectus. In the event of any
Suspension, the Company will use its best efforts to cause the use of the
Prospectus so suspended to be resumed as soon as reasonably practicable within
20 days after the delivery of a Suspension Notice to the Purchaser. In addition
to and without limiting any other remedies (including, without limitation, at
law or at equity) available to the Purchaser, the Purchaser shall be entitled to
specific performance in the event that the Company fails to comply with the
provisions of this Section 2(c).

                                       25
<PAGE>

              (d) Provided that a Suspension is not then in effect the Purchaser
may sell Shares under the Registration Statement, provided that it arranges for
delivery of a current Prospectus to the transferee of such Shares. Upon receipt
of a request therefor, the Company has agreed to provide an adequate number of
current Prospectuses to the Purchaser and to supply copies to any other parties
requiring such Prospectuses.

     Indemnification.  For the purpose of this Section 3:

         (i)   the term "Selling Stockholder" shall include each Purchaser and
any affiliate of such Purchaser;

         (ii)  the term "Registration Statement" shall include any final
Prospectus, exhibit, supplement or amendment included in or relating to the
Registration Statement referred to in Section 1; and

         (iii) the term "untrue statement" shall include any untrue statement or
alleged untrue statement, or any omission or alleged omission to state in the
Registration Statement a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

              (a) The Company agrees to indemnify and hold harmless each Selling
Stockholder from and against any losses, claims, damages or liabilities to which
such Selling Stockholder may become subject (under the Securities Act or
otherwise) insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon (i) any untrue
statement of a material fact contained in each Registration Statement, or (ii)
any failure by the Company to fulfill any undertaking included in each
Registration Statement, and the Company will reimburse such Selling Stockholder
for any reasonable legal or other expenses reasonably incurred in investigating,
defending or preparing to defend any such action, proceeding or claim, or
preparing to defend any such action, proceeding or claim, provided, however,
that the Company shall not be liable in any such case to the extent that such
loss, claim, damage or liability arises out of, or is based upon, an untrue
statement made in such Registration Statement in reliance upon and in conformity
with written information furnished to the Company by or on behalf of such
Selling Stockholder specifically for use in preparation of the Registration
Statement or the failure of such Selling Stockholder to comply with its
covenants and agreements contained in Section 2 hereof respecting sale of the
Shares or any statement or omission in any Prospectus that is corrected in any
subsequent Prospectus that was delivered to the Purchaser prior to the pertinent
sale or sales by the Purchaser.

                                       26
<PAGE>

              (b) Each Purchaser, separately and not jointly, agrees to
indemnify and hold harmless the Company (and each person, if any, who controls
the Company within the meaning of Section 15 of the Securities Act, each officer
of the Company who signs each Registration Statement and each director of the
Company) from and against any losses, claims, damages or liabilities to which
the Company (or any such officer, director or controlling person) may become
subject (under the Securities Act or otherwise), insofar as such losses, claims,
damages or liabilities (or actions or proceedings in respect thereof) arise out
of, or are based upon, (i) any failure to comply with the covenants and
agreements contained in Section 2 hereof respecting sale of the Shares, or (ii)
any untrue statement of a material fact contained in such Registration Statement
if such untrue statement was made in reliance upon and in conformity with
written information furnished by or on behalf of the Purchaser specifically for
use in preparation of such Registration Statement, and the Purchaser will
reimburse the Company (or such officer, director or controlling person), as the
case may be, for any legal or other expenses reasonably incurred in
investigating, defending or preparing to defend any such action, proceeding or
claim; provided that the Purchaser's obligation to indemnify the Company shall
be limited to the net amount received by the Purchaser from the sale of the
Shares.

              (c) Promptly after receipt by any indemnified person of a notice
of a claim or the beginning of any action in respect of which indemnity is to be
sought against an indemnifying person pursuant to this Section 3, such
indemnified person shall notify the indemnifying person in writing of such claim
or of the commencement of such action, but the omission to so notify the
indemnifying party will not relieve it from any liability which it may have to
any indemnified party under this Section 3 (except to the extent that such
omission materially and adversely affects the indemnifying party's ability to
defend such action) or from any liability otherwise than under this Section 3.
Subject to the provisions hereinafter stated, in case any such action shall be
brought against an indemnified person, the indemnifying person shall be entitled
to participate therein, and, to the extent that it shall elect by written notice
delivered to the indemnified party promptly after receiving the aforesaid notice
from such indemnified party, shall be entitled to assume the defense thereof,
with counsel reasonably satisfactory to such indemnified person. After notice
from the indemnifying person to such indemnified person of its election to
assume the defense thereof, such indemnifying person shall not be liable to such
indemnified person for any legal expenses subsequently incurred by such
indemnified person in connection with the defense thereof, provided, however,
that if there exists or shall exist a conflict of interest that would make it
inappropriate, in the opinion of counsel to the indemnified person, for the same
counsel to represent both the indemnified person and such indemnifying person or
any affiliate or associate thereof, the indemnified person shall be entitled to
retain its own counsel at the expense of such indemnifying person; provided,
however, that no indemnifying person shall be responsible for the fees and
expenses of more than one separate counsel (together with appropriate local
counsel) for all indemnified parties. In no event shall any indemnifying person
be liable in respect of any amounts paid in settlement of any action unless the
indemnifying person shall have approved the terms of such settlement; provided
that such consent shall not be unreasonably withheld. No indemnifying person
shall, without the prior written consent of the indemnified person, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified person is or could have been a party and indemnification could have
been sought hereunder by such indemnified person, unless such settlement
includes an unconditional release of such indemnified person from all liability
on claims that are the subject matter of such proceeding.

                                       27
<PAGE>

              (d) If the indemnification provided for in this Section 3 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to therein,
then each indemnifying party shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative fault of the Company on the one hand and the Purchaser
on the other in connection with the statements or omissions or other matters
which resulted in such losses, claims, damages or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations. The
relative fault shall be determined by reference to, among other things, in the
case of an untrue statement, whether the untrue statement relates to information
supplied by the Company on the one hand or a Purchaser on the other and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement. The Company and the Purchaser agree
that it would not be just and equitable if contribution pursuant to this
subsection (d) were determined by pro rata allocation or by any other method of
allocation which does not take into account the equitable considerations
referred to above in this subsection (d). 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 subsection (d) 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. Notwithstanding the provisions of this subsection (d) Purchaser shall
not be required to contribute any amount in excess of the amount by which the
net amount received by Purchaser from the sale of the Shares to which such loss
relates exceeds the amount of any damages which such Purchaser has otherwise
been required to pay by reason of such untrue statement. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

              (e) The parties to this Agreement hereby acknowledge that they are
sophisticated business persons who were represented by counsel during the
negotiations regarding the provisions hereof including, without limitation, the
provisions of this Section 3, and are fully informed regarding said provisions.
They further acknowledge that the provisions of this Section 3 fairly allocate
the risks in light of the ability of the parties to investigate the Company and
its business in order to assure that adequate disclosure is made in the
Registration Statement as required by the Act and the Exchange Act. The parties
are advised that federal or state public policy as interpreted by the courts in
certain jurisdictions may be contrary to certain of the provisions of this
Section 3, and the parties hereto hereby expressly waive and relinquish any
right or ability to assert such public policy as a defense to a claim under this
Section 3 and further agree not to attempt to assert any such defense.

                                       28
<PAGE>

     Termination of Conditions and Obligations. The conditions precedent imposed
by this Schedule B upon the transferability of the Shares shall cease and
terminate as to any particular number of the Shares when such Shares shall have
been effectively registered under the Securities Act and sold or otherwise
disposed of in accordance with the intended method of disposition set forth in
the Registration Statement covering such Shares or Warrant Shares or at such
time as an opinion of counsel satisfactory to the Company shall have been
rendered to the effect that such conditions are not necessary in order to comply
with the Securities Act.

     Information Available. So long as the Registration Statement is effective
covering the resale of Shares owned by the Purchaser, the Company will furnish
to the Purchaser:

              (a) as soon as practicable after it is available, one copy of (i)
its Annual Report to Stockholders (which Annual Report shall contain financial
statements audited in accordance with generally accepted accounting principles
by a national firm of certified public accountants), (ii) its Annual Report on
Form 10-K and (iii) its Quarterly Reports on Form 10-Q (the foregoing, in each
case, excluding exhibits);

              (b) upon the request of the Purchaser, all exhibits excluded by
the parenthetical to subparagraph (a) of this Section 22.5 as filed with the SEC
and all other information that is made available to shareholders; and

              (c) upon the reasonable request of the Purchaser, an adequate
number of copies of the Prospectuses to supply to any other party requiring such
Prospectuses; and the Company, upon the reasonable request of the Purchaser,
will meet with the Purchaser or a representative thereof at the Company's
headquarters to discuss all information relevant for disclosure in the
Registration Statement covering the Shares and will otherwise cooperate with any
Purchaser conducting an investigation for the purpose of reducing or eliminating
such Purchaser's exposure to liability under the Securities Act, including the
reasonable production of information at the Company's headquarters; provided,
that the Company shall not be required to disclose any confidential information
to or meet at its headquarters with any Purchaser until and unless the Purchaser
shall have entered into a confidentiality agreement in form and substance
reasonably satisfactory to the Company with the Company with respect thereto.

     Failure to Timely Register Shares. If the Company fails to comply with
Section 1(a) of this Schedule A, then Company shall pay each Purchaser an amount
equal to 2% of Purchaser's investment in the Company for each full or partial
month that Company has not fulfilled its obligation and if the Company fails to
comply with Section 1(b) of this Schedule A, then Company shall pay each
Purchaser an amount equal to .066667% of Purchaser's investment for each day
that Company has not fulfilled its obligation, provided that the default amount
shall not be paid more than once with respect to any particular day (i.e., in
the event that Company defaults under both Sections 1(a) and 1(b)).

of the Offering Materials, respectively. The Company undertakes no obligation to
publicly revise these forward-looking statements, to reflect events or
circumstances that may arise after the date hereof.

COMPETITION. The industries in which the Company competes through its
subsidiaries are all highly competitive. The Company competes against a number
of local, regional and national manufacturers in each of its business segments,
many of which have been in existence longer than the Company and some of which
have substantially greater financial resources than the Company. The Company
believes that any competition from new entrants that are large corporations may
be able to compete with the Company on the basis of price and as a result may
have a material adverse affect on the results of operations of the Company. In
addition, there can be no assurance that other companies will not develop new or
enhanced products that are either more effective than the Company's or would
render the Company's products non-competitive or obsolete.

DEPENDENCE ON KEY PERSONNEL. The Company is highly dependent on the experience
of its management in the continuing development of its operations. The loss of
the services of certain of these individuals, particularly Richard J. Blum,
President of the Company, would have a material adverse effect on the Company's
business. The Company's future success will depend in part on its ability to
attract and retain qualified personnel to manage the development and future
growth of the Company. There can be no assurance that it will be successful in
attracting and retaining such personnel. The failure to recruit additional key
personnel could have a material adverse effect on the Company's business,
financial condition and results of operations.

CONTINUED CONTROL BY MANAGEMENT. Assuming the sale of $2,500,000 of Units at
$3.00 a Unit, management of the Company will beneficially own approximately 68%
of the Company's outstanding Common Stock following the sale of the Units
(assuming the exercise of warrants and options held by management that are
exercisable as of the date hereof). The Company's stockholders do not have the
right to cumulative voting in the election of directors. Accordingly, present
stockholders will be in a position to exert control over the business and
operations of the Company, including the election of directors of the Company.

DEPENDENCE UPON THIRD-PARTY SUPPLIERS. Although the Company is not dependent on
any one supplier, the Company is dependent on the ability of its third-party
suppliers to supply the Company's raw materials, as well as certain specific
component parts. Ceco Filters, Inc. ("Filters"), in particular, purchases all of
its chemical grade fiberglass from one supplier, which Filters believes is the
only domestic supplier of such fiberglass, and certain specialty items from only
two suppliers. Failure by the Company's third-party suppliers to meet the
Company's requirements could have a material adverse effect on the Company.
There can be no assurance that the Company's third-party suppliers will dedicate
sufficient resources to meet the Company's scheduled delivery requirements or
that the Company's suppliers will have sufficient resources to satisfy the
Company's requirements during any period of sustained demand. Failure of
manufacturers or suppliers to supply, or delays in supplying, the Company with
raw materials or certain components, or allocations in the supply of certain
high demand raw components could materially adversely affect the Company's
operations and ability to meet its own delivery schedules on a timely and
competitive basis.

PATENTS. The Company's subsidiaries hold various patents and licenses relating
to certain of its products. There can be no assurance as to the breadth or
degree of protection that existing or future patents, if any, may afford the
Company, that the Company's patents will be upheld, if challenged, or that
competitors will not develop similar or superior methods or products outside the
protection of any patent issued to the Company or its subsidiaries. Although the
Company believes that its subsidiaries' patents and the Company's subsidiaries'
products do not and will not infringe patents or violate the proprietary rights
of others, it is possible that the Company's existing patent rights may not be
valid or that infringement of existing or future patents or proprietary rights
may occur. In the event the Company's products infringe patents or proprietary
rights of others, the Company may be required to modify the design of its
products or obtain a license for certain technology. There can be no assurance
that the Company will be able to do so in a timely manner, upon acceptable terms
and conditions, or at all. Failure to do any of the foregoing could have a
material adverse effect upon the Company. In addition, there can be no assurance
that the Company will have the financial or other resources necessary to enforce
or defend a patent infringement or proprietary rights violation action which may
be brought against it. Moreover, if the Company's products infringe patents or
proprietary rights of others, the Company could, under certain circumstances,
become liable for damages, which also could have a material adverse effect on
the Company.

NEW PRODUCT DEVELOPMENT AND ACQUISITIONS The air pollution control and
filtration industry is characterized by ongoing technological developments and
changing customer requirements. As a result, the Company's success and continued
growth depend, in part, on its ability in a timely manner to develop or acquire
rights to, and successfully introduce into the marketplace, enhancements of
existing products or new products that incorporate technological advances, meet
customer requirements and respond to products developed by the Company's
competition. There can be no assurance that the Company will be successful in
developing or acquiring such rights to products on a timely basis or that such
products will adequately address the changing needs of the marketplace.

                                       31
<PAGE>

TECHNOLOGICAL AND REGULATORY CHANGE The air pollutions control and filtration
industry is characterized by changing technology, competitively imposed process
standards and regulatory requirements, each of which influences the demand for
the Company's products and services. Changes in legislative, regulatory or
industrial requirements may render certain of the Company's filtration products
and processes obsolete. Acceptance of new products may also be affected by the
adoption of new government regulations requiring stricter standards. The
Company's ability to anticipate changes in technology and regulatory standards
and to develop and introduce new and enhanced products successfully on a timely
basis will be a significant factor in the Company's ability to grow and to
remain competitive. There can be no assurance that the Company will be able to
achieve the technological advances that may be necessary for it to remain
competitive or that certain of its products will not become obsolete.

LEVERAGE. The Company is highly leveraged. It currently has loan facilities with
PNC Bank, National Association, Bank One, N.A. and Fifth Third Bank. The terms
of such loan facilities have been revised through four separate amendments in
order to alter some of the financial covenants made by the Company to prevent
the Company from being in default of such covenants.

WE MAY NEED TO OBTAIN ADDITIONAL FINANCING. The Company believes that with cash
on hand and proceeds from expected sales that it has sufficient proceeds to meet
cash requirements for the next twelve months.

However, the Company may need to raise additional funds to:

     -   Finance unanticipated working capital requirements;

     -   Pay for increased operating expenses or shortfalls in anticipated
         revenues;

     -   Fund increases in research and related expenditures;

     -   Develop new technology, products or services;

     -   Respond to competitive pressures; and

     -   Support strategic and industry relationships.

     There is no assurance that additional financing will be available on
terms favorable to the Company, or at all. If adequate funds are not available
to the Company then it may not be able to continue operations or take advantage
of opportunities.

THE UNITS, SHARES, AND WARRANTS HEREBY SUBSCRIBED FOR WILL BE UNREGISTERED,
RESTRICTED SECURITIES THAT WILL NOT BE FREELY TRADABLE All of the Units, Shares
and Warrants will be restricted securities under the Securities Act and
applicable state securities laws. These Units, Shares and Warrants cannot be
transferred without registration under the Securities Act and any applicable
state securities laws unless an exemption is available and an opinion of
counsel, if requested by the Company, to that effect is obtained. Currently,
there is no public market for the Units or Warrants and the Company has no plans
to ever effect a registered public offering of the Units or Warrants. The
transferability of Shares will be substantially restricted under federal and
state securities laws. For these and other reasons, there may be no trading in
the Shares and Warrants. While the Company anticipates filing a Form S-1 to
allow the public trading of the Shares, there is no guarantee that the Company
will be successful.

         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. THEY HAVE BEEN ACQUIRED
         SOLELY FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH,
         THE SALE OR DISTRIBUTION THEREOF. THEY MAY NOT BE SOLD, OFFERED FOR
         SALE, PLEDGED, HYPOTHECATED OR OTHERWISE DISTRIBUTED IN THE ABSENCE OF
         AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF
         COUNSEL, SATISFACTORY IN FORM AND SUBSTANCE TO THE COMPANY THAT SUCH
         REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933, AS
         AMENDED AND ANY APPLICABLE STATE SECURITIES LAWS.


                                     WARRANT

No.                                                         December 31, 2001


                  To Purchase _______ Shares of Common Stock of
        Ceco Environmental Corp., a New York corporation (the "Company")

     Number of Shares; Exercise Price; Term. This certifies that for good and
valuable consideration, receipt and sufficiency of which are hereby acknowledged
__________________ ("Holder") is entitled, upon the terms and subject to the
conditions hereinafter set forth, at any time after the date hereof and at or
prior to 11:59 p.m. Central Time, on December 31, 2006 (the "Expiration Time"),
but not thereafter, to acquire from the Company, in whole or in part, from time
to time, up to ________________________ (____________) fully paid and
nonassessable shares (the "Shares") of common stock, $____ par value, of the
Company ("Common Stock"), at a purchase price of $3.60 per share (the "Exercise
Price"). The right to purchase all of the Shares under the Warrant shall vest
immediately upon issuance of this Warrant. The number of Shares, type of
security and Exercise Price are subject to adjustment as provided herein, and
all references to "Common Stock" and "Exercise Price" herein shall be deemed to
include any such adjustment or series of adjustments.

     Exercise of Warrant. The purchase rights represented by this Warrant are
exercisable by the Holder, in whole or in part, at any time, or from time to
time, prior to the Expiration Time and after the time a registration statement
registering the shares of Common Stock issuable upon exercise of this Warrant
has been declared effective by the Securities and Exchange Commission, by the
surrender of this Warrant and the Notice of Exercise annexed hereto, all duly
completed and executed on behalf of the Holder, at the office of the Company in
Toronto, Ontario, Canada (or such other office or agency of the Company as it
may designate by notice in writing to the Holder at the address of the Holder
appearing on the books of the Company) and upon payment of the Exercise Price
for the Shares thereby purchased (by cash, certified or cashier's check, or wire
transfer payable to the Company). Thereupon, the Holder as the holder of this
Warrant, shall be entitled to receive from the Company a stock certificate in
proper form representing the number of Shares so purchased, and a new Warrant in
substantially identical form and dated as of such exercise for the purchase of
that number of Shares equal to the difference, if any, between the number of
Shares subject hereto and the number of Shares as to which this Warrant is so
exercised.

                                       1
<PAGE>

     Issuance of Shares. Certificates for Shares purchased hereunder shall be
delivered to the Holder within a reasonable time after the date on which this
Warrant shall have been exercised in accordance with the terms hereof. All
Shares that may be issued upon the exercise of this Warrant shall, upon such
exercise, be duly and validly authorized and issued, fully paid and
nonassessable and free from all taxes, liens and charges in respect of the
issuance thereof (other than liens or charges created by or imposed upon the
Holder as the holder of the Warrant or taxes in respect of any transfer
occurring contemporaneously or otherwise specified herein). The Company agrees
that the Shares so issued shall be and shall for all purposes be deemed to have
been issued to the Holder as the record owner of such Shares as of the close of
business on the date on which this Warrant shall have been exercised or
converted in accordance with the terms hereof. The Company will at all times
reserve and keep available, solely for issuance, sale and delivery upon the
exercise of this Warrant, such number of Shares, equal to the number of such
Shares purchasable upon the exercise of this Warrant.

     No Fractional Shares or Scrip. No fractional Shares or scrip representing
fractional Shares shall be issued upon the exercise of this Warrant. In lieu of
any fractional Warrant Share to which the Holder as the holder would otherwise
be entitled, the Holder shall be entitled, at its option, to receive either (i)
a cash payment equal to the excess of fair market value for such fractional
Warrant Share above the Exercise Price for such fractional share (as determined
in good faith by the Company) or (ii) a whole Warrant Share if the Holder
tenders the Exercise Price for one whole share.

     No Rights as Shareholders. This Warrant does not entitle the Holder as a
holder hereof to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof.

     Exchange and Registry of Warrant. This Warrant is exchangeable, upon the
surrender hereof by Holder as the registered holder at the above-mentioned
office or agency of the Company, for a new Warrant of substantially identical
form and dated as of such exchange. The Company shall maintain at the
above-mentioned office or agency a registry showing the name and address of
Holder as the registered Holder of this Warrant. This Warrant may be surrendered
for exchange or exercise, in accordance with its terms, at the office of the
Company, and the Company shall be entitled to rely in all respects, prior to
written notice to the contrary, upon such registry.

     Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant, and in the case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it, and upon
reimbursement to the Company of all reasonable expenses incidental thereto, and
upon surrender and cancellation of this Warrant, if mutilated, the Company will
make and deliver a new Warrant of like tenor and dated as of such cancellation
and reissuance, in lieu of this Warrant.

                                       2
<PAGE>

     Saturdays, Sundays, Holidays, etc. If the last or appointed day for the
taking of any action or the expiration of any right required or granted herein
shall be a Saturday or a Sunday or shall be a legal holiday, then such action
may be taken or such right may be exercised on the next succeeding day not a
Saturday or a Sunday or a legal holiday.

     Adjustments of Rights. The purchase price per Share and/or the number of
Shares purchasable hereunder are subject to adjustment from time to time as
follows:

          Merger or Consolidation. If at any time there shall be a merger or a
     consolidation of the Company with or into another corporation when the
     Company is not the surviving corporation, then, as part of such merger or
     consolidation, lawful provision shall be made so that the Holder as the
     holder of this Warrant shall thereafter be entitled to receive upon
     exercise of this Warrant, during the period specified herein and upon
     payment of the aggregate Exercise Price then in effect, the number of
     shares of stock or other securities or property (including cash) of the
     successor corporation resulting from such merger or consolidation, to which
     the Holder as the holder of the stock deliverable upon exercise of this
     Warrant would have been entitled in such merger or consolidation if this
     Warrant had been exercised immediately before such merger or consolidation.
     In any such case, appropriate adjustment shall be made in the application
     of the provisions of this Warrant with respect to the rights and interests
     of the Holder as the holder of this Warrant after the merger or
     consolidation. This provision shall apply to successive mergers or
     consolidations.

          Reclassification, Recapitalization, etc. If the Company at any time
     shall, by subdivision, combination or reclassification of securities,
     recapitalization, automatic conversion, or other similar event affecting
     the number or character of outstanding shares of Common Stock, or
     otherwise, change any of the securities as to which purchase rights under
     this Warrant exist into the same or a different number of securities of any
     other class or classes, this Warrant shall thereafter represent the right
     to acquire such number and kind of securities as would have been issuable
     as the result of such change with respect to the securities that were
     subject to the purchase rights under this Warrant immediately prior to such
     subdivision, combination, reclassification or other change.

          Split, Subdivision or Combination of Shares. If the Company at any
     time while this Warrant remains outstanding and unexpired shall split,
     subdivide or combine the securities as to which purchase rights under this
     Warrant exist, the Exercise Price shall be proportionately decreased in the
     case of a split or subdivision or proportionately increased in the case of
     a combination.

          Common Stock Dividends. If the Company at any time while this Warrant
     is outstanding and unexpired shall pay a dividend with respect to Common
     Stock payable in shares of Common Stock, or make any other distribution
     with respect to Common Stock payable in shares of Common Stock, then the
     Exercise Price shall be adjusted, from and after the date of determination
     of the shareholders entitled to receive such dividend or distribution, to
     that price determined by multiplying the Exercise Price in effect
     immediately prior to such date of determination by a fraction (i) the
     numerator of which shall be the total number of shares of Common Stock
     outstanding immediately prior to such dividend or distribution, and (ii)
     the denominator of which shall be the total number of shares of Common
     Stock outstanding immediately after such dividend or distribution.

                                       3

     Adjustment of Exercise Price for Dilutive Events. If and whenever on or
after the date of this Warrant but on or prior to the date two years after the
Form S-1 described in Section 17 is declared effective by the SEC, the Company
issues, sells or grants shares of Common Stock, or in accordance with Section 11
below is deemed to have issued, sold or granted shares of Common Stock for
consideration per share less than the Exercise Price (the "Dilutive Price") in
effect immediately prior to the time of such issuance or sale (a "Dilutive
Event"), then forthwith upon the occurrence of any such Dilutive Event the
Exercise Price shall be reduced so that the Exercise Price in effect immediately
following the Dilutive Event will equal the Dilutive Price; provided, however,
that shares of Common Stock issued for consideration per share less than the
Exercise Price shall not be taken into account under this Section 10 if such
shares are issued in connection with: (i) the exercise of warrants and options
outstanding as of the date of this Warrant, (ii) the issuance of options or
warrants or the receipt of shares or exercise of such options or warrants with
respect to employees and officers of the Company or its subsidiaries pursuant to
the Company's 1997 Stock Option Plan (other than to Affiliates of the Company)
or the 1999 Employee Stock Purchase Plan; (iii) the issuance of warrants or
options and the receipt of stock on exercise of such options or warrants with
respect to directors of the Company and up to 250,000 options or warrants to be
issued to Consultants of the Company, (iv) reincorporation of the Company in
Delaware, or (v) any merger, acquisition, bank financing or lending transaction
approved by the Company's Board of Directors provided that no Affiliate of the
Company is a party to such transactions.

     Issuance and Sale of Shares of Common Stock. For purposes of determining
the adjusted Exercise Price pursuant to Section 10 above, the following events
shall be deemed to be an issuance and sale of shares of Common Stock by the
Company:

          Issuance of Rights or Options. If (i) the Company, in any manner,
     hereafter grants any rights or options to subscribe for, or to purchase,
     shares of Common Stock, or any securities convertible into or exchangeable
     for any shares of Common Stock (such rights or options referred to herein
     as "Options" and such convertible or exchangeable securities referred to
     herein as "Convertible Securities") and (ii) the price per share of Common
     Stock issuable upon the exercise of such Options or upon conversion or
     exchange of such Convertible Securities is less than the Exercise Price in
     effect immediately prior to the time of the granting of such Options, then
     the shares of Common Stock issuable upon the exercise of such Options or
     upon conversion or exchange of such Convertible Securities will be deemed
     to have been issued and sold by the Company for such lesser price per
     share. For the purposes of this Section 11 the "Price Per Share" is
     determined by dividing (i) the total amount, if any, received by the
     Company as consideration for the granting of such Options, plus the minimum
     aggregate amount of additional consideration payable to the Company upon
     exercise of all such Options, plus in the case of such Options which relate
     to Convertible Securities, the minimum aggregate amount of additional
     consideration, if any, payable to the Company upon the issuance or sale of
     such Convertible Securities and the conversion or exchange thereof, by (ii)
     the total maximum number of shares of Common Stock issuable upon the
     exercise of such Options or upon the conversion or exchange of all such
     Convertible Securities issuable upon the exercise of such Options (without
     taking into account potential anti-dilution adjustments or the terms of
     such investments). No further adjustment of the Exercise Price will be made
     when Convertible Securities are actually issued upon the exercise of such
     Options or when shares of Common Stock are actually issued upon the
     exercise of such Options or the conversion or exchange of such Convertible
     Securities.

                                       4
<PAGE>

          Calculation of Consideration Received. If any Shares, Options or
     Convertible Securities are issued or sold or deemed to have been issued or
     sold for cash, the consideration received therefor or the Price Per Unit,
     as the case may be, will be deemed to be the net amount received or to be
     received, respectively, by the Company therefor. In case any Shares,
     Options or Convertible Securities are issued or sold for a consideration
     other than cash, the amount of the consideration other than cash received
     by the Company or the non-cash portion of the Price Per Share, as the case
     may be, will be the fair market value of such consideration received or to
     be received, respectively, by the Company. If any Shares, Options or
     Convertible Securities are issued in connection with any merger in which
     the Company is the surviving Company, the amount of consideration therefor
     will be deemed to be the fair value of such portion of the net assets and
     business of the non-surviving Company as is attributable to such Shares,
     Options or Convertible Securities, as the case may be. The fair value of
     any consideration other than cash and marketable securities will be
     determined by the Company.

          Integrated Transactions. In case any Option is issued in connection
     with the issuance or sale of other securities of the Company, together
     comprising one integrated transaction in which no specific consideration is
     allocated to such Option by the parties thereto, the Option will be deemed
     to have been issued for a consideration of $.01.

          Upon the expiration or termination of any such Option or Convertible
     Security which has not been exercised in whole or in part, the Exercise
     Price shall be recomputed as if the Dilutive Event giving rise to such
     adjustment in the Exercise Price had never occurred and the Warrant Price
     and the number of Shares for which the Warrant is exercisable shall be
     recomputed to the extent that Holder has not exercised the Warrant
     (determined as if the unexercised part of the Warrant were the only portion
     of the Warrant issued to the Holder on the date hereof).

     Adjustment of Number of Shares. Upon each adjustment in the Exercise Price
pursuant to Sections 9 or 10 hereof, the number of Shares purchasable hereunder
shall be adjusted, to the nearest whole Share, to the product obtained by
multiplying the number of Shares purchasable immediately prior to such
adjustment by a fraction (i) the numerator of which shall be the Exercise Price
immediately prior to such adjustment, and (ii) the denominator of which shall be
the Exercise Price immediately after such adjustment.

     Notice of Adjustments; Notices. Whenever the Exercise Price or number or
type of securities issuable hereunder shall be adjusted pursuant to Sections 9,
10 or 12 hereof, the Company shall issue and provide to the Holder as the holder
of this Warrant, within ten (10) days after the event requiring the adjustment,
a certificate signed by an officer of the Company setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated and the Exercise Price and number
of Shares purchasable hereunder after giving effect to such adjustment.

                    Holders of Warrants issued on the date hereof in the
                    aggregate) and the registration of the Shares pursuant to
                    the Registration Statement and the Purchasers shall pay any
                    commissions, mark-ups, or similar selling expenses; and

               advise the Holder, promptly after it shall receive notice or
                    obtain knowledge of the issuance of any stop order by the
                    SEC delaying or suspending the effectiveness of the
                    Registration Statement or of the initiation or threat of any
                    proceeding for that purpose; and it will promptly use its
                    reasonable efforts to prevent the issuance of any stop order

                    if such stop order should be issued.

the Holder being deemed an underwriter by the SEC shall not relieve the Company
of any obligations it has hereunder.

                    forth in the Registration Statement regarding the Holder or
                    its plan of distribution.

               Except in the event that paragraph (c) below applies, the Company
                    shall (i) if deemed necessary by the Company, prepare and
                    file from time to time with the SEC a post-effective
                    amendment to each Registration Statement or a supplement to
                    the related Prospectus or a supplement or amendment to any
                    document incorporated therein by reference or file any other
                    required document so that such Registration Statement will
                    not contain an untrue statement of a material fact or omit
                    to state a material fact required to be stated therein or
                    necessary to make the statements therein not misleading, and
                    so that, as thereafter delivered to purchasers of the Shares
                    being sold thereunder, such Prospectus will not contain an
                    untrue statement of a material fact or omit to state a
                    material fact required to be stated therein or necessary to
                    make the statements therein, in light of the circumstances
                    under which they were made, not misleading; (ii) provide the
                    Holder copies of any documents filed pursuant to Section
                    17.2(b)(i); and (iii) inform each Holder that the Company
                    has complied with its obligations in Section 17.2(b)(i) (or
                    that, if the Company has filed a post-effective amendment to
                    the Registration Statement which has not yet been declared
                    effective, the Company will notify the Holder to that
                    effect, will use its reasonable efforts to secure the
                    effectiveness of such post-effective amendment as promptly
                    as possible and will promptly notify the Holder pursuant to
                    Section 17.2(b)(i) hereof when the amendment has become
                    effective).

               Subject to paragraph (d) below, in the event (i) of any request
                    by the SEC or any other federal or state governmental
                    authority during the period of effectiveness of each
                    Registration Statement for amendments or supplements to a
                    Registration Statement or related Prospectus or for
                    additional information; (ii) of the issuance by the SEC or
                    any other federal or state governmental authority of any
                    stop order suspending the effectiveness of a Registration
                    Statement or the initiation of any proceedings for that
                    purpose; (iii) of the receipt by the Company of any
                    notification with respect to the suspension of the
                    qualification or exemption from qualification of any of the
                    Shares for sale in any jurisdiction or the initiation or
                    threatening of any proceeding for such purpose; or (iv) of
                    any event or circumstance which, upon the advice of its
                    counsel, necessitates the making of any changes in such
                    Registration Statement or Prospectus, or any document
                    incorporated or deemed to be incorporated therein by
                    reference, so that, in the case of the Registration
                    Statement, it will not contain any untrue statement of a
                    material fact or any omission to state a material fact
                    required to be stated therein or necessary to make the
                    statements therein not misleading, and that in the case of
                    the Prospectus, it will not contain any untrue statement of
                    a material fact or any omission to state a material fact
                    required to be stated therein or necessary to make the
                    statements therein, in the light of the circumstances under
                    which they were made, not misleading; then the Company shall
                    deliver a certificate in writing to the Holder (the
                    "Suspension Notice") to the effect of the foregoing and,
                    upon receipt of such Suspension Notice, the Holder will
                    refrain from selling any Shares pursuant to such
                    Registration Statement (a "Suspension") until the Holder's
                    receipt of copies of a supplemented or amended Prospectus
                    prepared and filed by the Company, or until it is advised in
                    writing by the Company that the current Prospectus may be
                    used, and has received copies of any additional or
                    supplemental filings that are incorporated or deemed
                    incorporated by reference in any such Prospectus. In the
                    event of any Suspension, the Company will use its best
                    efforts to cause the use of the Prospectus so suspended to
                    be resumed as soon as reasonably practicable within 20 days
                    after the delivery of a Suspension Notice to the Holder. In
                    addition to and without limiting any other remedies
                    (including, without limitation, at law or at equity)
                    available to the Holder, the Holder shall be entitled to
                    specific performance in the event that the Company fails to
                    comply with the provisions of this Section 17.2(c).

               Provided that a Suspension is not then in effect the Holder may
                    sell Shares under the Registration Statement, provided that
                    it arranges for delivery of a current Prospectus to the
                    transferee of such Shares. Upon receipt of a request
                    therefor, the Company has agreed to provide an adequate
                    number of current Prospectuses to the Holder and to supply
                    copies to any other parties requiring such Prospectuses.

     Indemnification. For the purpose of this Section 17.3:

               the  term "Selling Stockholder" shall include the Holder and any
                    affiliate of such Holder;

               the  term "Registration Statement" shall include any final
                    Prospectus, exhibit, supplement or amendment included in or
                    relating to the Registration Statement referred to in
                    Section 17.1; and

               the  term "untrue statement" shall include any untrue statement
                    or alleged untrue statement, or any omission or alleged
                    omission to state in the Registration Statement a material
                    fact required to be stated therein or necessary to make the
                    statements therein, in the light of the circumstances under
                    which they were made, not misleading.

               The  Company agrees to indemnify and hold harmless each Selling
                    Stockholder from and against any losses, claims, damages or
                    liabilities to which such Selling Stockholder may become
                    subject (under the Securities Act or otherwise) insofar as
                    such losses, claims, damages or liabilities (or actions or
                    proceedings in respect thereof) arise out of, or are based
                    upon (i) any untrue statement of a material fact contained
                    in each Registration Statement, or (ii) any failure by the
                    Company to fulfill any undertaking included in each
                    Registration Statement, and the Company will reimburse such
                    Selling Stockholder for any reasonable legal or other
                    expenses reasonably incurred in investigating, defending or
                    preparing to defend any such action, proceeding or claim, or
                    preparing to defend any such action, proceeding or claim,
                    provided, however, that the Company shall not be liable in
                    any such case to the extent that such loss, claim, damage or
                    liability arises out of, or is based upon, an untrue
                    statement made in such Registration Statement in reliance
                    upon and in conformity with written information furnished to
                    the Company by or on behalf of such Selling Stockholder
                    specifically for use in preparation of the Registration
                    Statement or the failure of such Selling Stockholder to
                    comply with its covenants and agreements contained in
                    Section 17.2 hereof respecting sale of the Shares or any
                    statement or omission in any Prospectus that is corrected in
                    any subsequent Prospectus that was delivered to the Holder
                    prior to the pertinent sale or sales by the Holder.

               The  Holder agrees to indemnify and hold harmless the Company
                    (and each person, if any, who controls the Company within
                    the meaning of Section 15 of the Securities Act, each
                    officer of the Company who signs each Registration Statement
                    and each director of the Company) from and against any
                    losses, claims, damages or liabilities to which the Company
                    (or any such officer, director or controlling person) may
                    become subject (under the Securities Act or otherwise),
                    insofar as such losses, claims, damages or liabilities (or
                    actions or proceedings in respect thereof) arise out of, or
                    are based upon, (i) any failure to comply with the covenants
                    and agreements contained in Section 17.2 hereof respecting
                    sale of the Shares, or (ii) any untrue statement of a
                    material fact contained in such Registration Statement if
                    such untrue statement was made in reliance upon and in
                    conformity with written information furnished by or on
                    behalf of the Holder specifically for use in preparation of
                    such Registration Statement, and the Holder will reimburse
                    the Company (or such officer, director or controlling
                    person), as the case may be, for any legal or other expenses
                    reasonably incurred in investigating, defending or preparing
                    to defend any such action, proceeding or claim; provided
                    that the Holder's obligation to indemnify the Company shall
                    be limited to the net amount received by the Holder from the
                    sale of the Shares.

               Promptly after receipt by any indemnified person of a notice of a
                    claim or the beginning of any action in respect of which
                    indemnity is to be sought against an indemnifying person
                    pursuant to this Section 17.3, such indemnified person shall
                    notify the indemnifying person in writing of such claim or
                    of the commencement of such action, but the omission to so
                    notify the indemnifying party will not relieve it from any
                    liability which it may have to any indemnified party under
                    this Section 17.3 (except to the extent that such omission
                    materially and adversely affects the indemnifying party's
                    ability to defend such action) or from any liability
                    otherwise than under this Section 17.3. Subject to the
                    provisions hereinafter stated, in case any such action shall
                    be brought against an indemnified person, the indemnifying
                    person shall be entitled to participate therein, and, to the
                    extent that it shall elect by written notice delivered to
                    the indemnified party promptly after receiving the aforesaid
                    notice from such indemnified party, shall be entitled to
                    assume the defense thereof, with counsel reasonably
                    satisfactory to such indemnified person. After notice from
                    the indemnifying person to such indemnified person of its
                    election to assume the defense thereof, such indemnifying
                    person shall not be liable to such indemnified person for
                    any legal expenses subsequently incurred by such indemnified
                    person in connection with the defense thereof, provided,
                    however, that if there exists or shall exist a conflict of
                    interest that would make it inappropriate, in the opinion of
                    counsel to the indemnified person, for the same counsel to
                    represent both the indemnified person and such indemnifying
                    person or any affiliate or associate thereof, the
                    indemnified person shall be entitled to retain its own
                    counsel at the expense of such indemnifying person;
                    provided, however, that no indemnifying person shall be
                    responsible for the fees and expenses of more than one
                    separate counsel (together with appropriate local counsel)
                    for all indemnified parties. In no event shall any
                    indemnifying person be liable in respect of any amounts paid
                    in settlement of any action unless the indemnifying person
                    shall have approved the terms of such settlement; provided
                    that such consent shall not be unreasonably withheld. No
                    indemnifying person shall, without the prior written consent
                    of the indemnified person, effect any settlement of any
                    pending or threatened proceeding in respect of which any
                    indemnified person is or could have been a party and
                    indemnification could have been sought hereunder by such
                    indemnified person, unless such settlement includes an
                    unconditional release of such indemnified person from all
                    liability on claims that are the subject matter of such
                    proceeding.

               If   the indemnification provided for in this Section 17.3 is
                    unavailable to or insufficient to hold harmless an
                    indemnified party under subsection (a) or (b) above in
                    respect of any losses, claims, damages or liabilities (or
                    actions or proceedings in respect thereof) referred to
                    therein, then each indemnifying party shall contribute to
                    the amount paid or payable by such indemnified party as a
                    result of such losses, claims, damages or liabilities (or
                    actions in respect thereof) in such proportion as is
                    appropriate to reflect the relative fault of the Company on
                    the one hand and the Holder on the other in connection with
                    the statements or omissions or other matters which resulted
                    in such losses, claims, damages or liabilities (or actions
                    in respect thereof), as well as any other relevant equitable
                    considerations. The relative fault shall be determined by
                    reference to, among other things, in the case of an untrue
                    statement, whether the untrue statement relates to
                    information supplied by the Company on the one hand or a
                    Holder on the other and the parties' relative intent,
                    knowledge, access to information and opportunity to correct
                    or prevent such untrue statement. The Company and the Holder
                    agree that it would not be just and equitable if
                    contribution pursuant to this subsection (d) were determined
                    by pro rata allocation or by any other method of allocation
                    which does not take into account the equitable
                    considerations referred to above in this subsection (d). 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 subsection (d)
                    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.
                    Notwithstanding the provisions of this subsection (d) Holder
                    shall not be required to contribute any amount in excess of
                    the amount by which the net amount received by Holder from
                    the sale of the Shares to which such loss relates exceeds
                    the amount of any damages which such Holder has otherwise
                    been required to pay by reason of such untrue statement. No
                    person guilty of fraudulent misrepresentation (within the
                    meaning of Section 11(f) of the Securities Act) shall be
                    entitled to contribution from any person who was not guilty
                    of such fraudulent misrepresentation.

               The  parties to this Agreement hereby acknowledge that they are
                    sophisticated business persons who were represented by
                    counsel during the negotiations regarding the provisions
                    hereof including, without limitation, the provisions of this
                    Section 17.3, and are fully informed regarding said
                    provisions. They further acknowledge that the provisions of
                    this Section 17.3 fairly allocate the risks in light of the
                    ability of the parties to investigate the Company and its
                    business in order to assure that adequate disclosure is made
                    in the Registration Statement as required by the Act and the
                    Exchange Act. The parties are advised that federal or state
                    public policy as interpreted by the courts in certain
                    jurisdictions may be contrary to certain of the provisions
                    of this Section 17.3, and the parties hereto hereby
                    expressly waive and relinquish any right or ability to
                    assert such public policy as a defense to a claim under this
                    Section 17.3 and further agree not to attempt to assert any
                    such defense.

     Termination of Conditions and Obligations. The conditions precedent imposed
by this Section 17 upon the transferability of the Shares shall cease and
terminate as to any particular number of the Shares when such Shares shall have
been effectively registered under the Securities Act and sold or otherwise
disposed of in accordance with the intended method of disposition set forth in
the Registration Statement covering such Shares or Warrant Shares or at such
time as an opinion of counsel satisfactory to the Company shall have been
rendered to the effect that such conditions are not necessary in order to comply
with the Securities Act.

     Information Available. So long as the Registration Statement is effective
covering the resale of Shares owned by the Holder, the Company will furnish to
the Holder:

               as   soon as practicable after it is available, one copy of (i)
                    its Annual Report to Stockholders (which Annual Report shall
                    contain financial statements audited in accordance with
                    generally accepted accounting principles by a national firm
                    of certified public accountants), (ii) its Annual Report on
                    Form 10-K and (iii) its Quarterly Reports on Form 10-Q (the
                    foregoing, in each case, excluding exhibits);

               upon the request of the Holder, all exhibits excluded by the
                    parenthetical to subparagraph (a) of this Section 17.5 as
                    filed with the SEC and all other information that is made
                    available to shareholders; and

               upon the reasonable request of the Holder, an adequate number of
                    copies of the Prospectuses to supply to any other party
                    requiring such Prospectuses; and the Company, upon the
                    reasonable request of the Holder, will meet with the Holder
                    or a representative thereof at the Company's headquarters to
                    discuss all information relevant for disclosure in the
                    Registration Statement covering the Shares and will
                    otherwise cooperate with any Holder conducting an
                    investigation for the purpose of reducing or eliminating
                    such Holder's exposure to liability under the Securities
                    Act, including the reasonable production of information at
                    the Company's headquarters; provided, that the Company shall
                    not be required to disclose any confidential information to
                    or meet at its headquarters with any Holder until and unless
                    the Holder shall have entered into a confidentiality
                    agreement in form and substance reasonably satisfactory to
                    the Company with the Company with respect thereto.

                                       13

the transferee is an "accredited investor" and that the transfer of the Warrant
to such transferee, the issuance of the Warrant Shares to the transferee and the

Securities Act of 1933 or the registration requirements of any state securities
laws.

entire agreement between the parties with respect to the subject matter hereof
and supersede all prior and contemporaneous arrangements or undertakings with
