                                     PART I

Item 1.  Business

         CECO Environmental Corp. ("CEC" or the "Company") was incorporated in
New York State in 1966. The Company owns 6,274,498 shares of common stock CECO
Filters, Inc. ("CECO"), representing 91.36% of CECO's outstanding common stock.
The Company has no significant operations nor does it hold any significant
assets other than CECO stock. CECO was incorporated July 25, 1985, and commenced
operations in August 1985.

         For a description of CECO's business and other information regarding
CECO, see "CECO Filters, Inc." below.

Recent Developments

         In 1997 management at CECO began to concentrate on targeting industrial
markets in addition to specialty markets by focusing on adding service
components to products offered. The acquisition of the business of Busch Co.,
described below, which provides engineering services as well as products was
part of the strategy. In addition, CECO began in 1997 to focus on offering a
facilities management service. The facilities management service combines
products and management services using industry leading computer technology.
Such service is also known as Computer Aided Facilities Management ("CAMF").

         To further implement its new focus, CECO funded U.S. Facilities
Management Company, Inc. ("USFM"), a Delaware corporation and a wholly-owned
subsidiary of CECO, with approximately an additional $400,000 to test its CAMF
service in Phoenix, Arizona. As part of its strategy, CECO in early 1998,
entered into an agreement with Western VAR Alliance, which will provide certain
skills that USFM lacks. Management plans to standardize the system being used by
USFM to allow CECO to use the system in new territories. CECO is also launching
an acquisition program to gain such additional geographical territories where
such a standardized strategy may be used.

         On September 25, 1997, pursuant to an Asset Purchase Agreement, New
Busch Co., Inc., a Delaware corporation ("Busch") which is a wholly-owned
subsidiary of CECO, acquired certain assets, and all rights and interests of,
Busch Co., a Pennsylvania corporation (the "Seller") for a purchase price of
$2,100,000 plus acquisition costs. The Seller was engaged in the business of
marketing, selling, designing and assembling ventilation, environmental and
process-related products, and also provided manufacturer's representative
services to certain companies or manufacturers in support of related businesses.
Seller's revenues in 1996 were slightly greater than the Company's consolidated
revenues in 1996.

         The assets and rights Busch acquired include (i) the machinery,
fixtures, leasehold improvements, vehicles and equipment of the Seller, (ii) all
inventory of the Seller, (iii) all contractual rights of the Seller, including
rights to purchase orders, sales orders, contracts-in-process 
                                                      
                                        3

<PAGE>



and similar agreements, (iv) certain items of prepaid expenses, (v) all
rights of the Seller in its patents, trademarks, service marks and licenses,
(vi) certain real property leasehold interests, (vii) the Seller's goodwill, and
(viii) all of the Seller's rights under employment agreements. The consideration
was determined by arm's length negotiations between Busch and the Seller. The
funds required for the acquisition were obtained using a credit facility
established by CECO with CoreStates Bank, N.A. and a loan from CEC. The closing
date was September 25, 1997, but was deemed to be effective as of July 1, 1997.

         In connection with such acquisition, Busch entered into an Employment,
Non-Compete and Confidentiality Agreement with Andrew M. Halapin, the majority
stockholder and President of the Seller, pursuant to which Mr. Halapin agreed to
be Busch's President and chief operating officer for approximately three years.
Included as compensation for Mr. Halapin's services was a $500,000 signing
bonus. For a description of Busch's business and other information regarding
Busch, see "New Busch Co., Inc." below.

         In October of 1997, for ease of administration, CECO transferred the
assets of Compliance Systems International, a Delaware corporation and a
wholly-owned subsidiary of CECO, to CECO.

         On October 1, 1997, the Board of Directors of the Company adopted the
CECO Environmental Corp. 1997 Stock Option Plan (the "Plan"). The stock options
are intended to qualify as incentive stock options and may be issued to
officers, employees, directors, and consultants of the Company and its
subsidiaries. One Million, Five Hundred Thousand shares of the Company's stock
has been reserved for issuance pursuant to the Plan. As of March 18, 1998,
313,320 options under the Plan have been issued. Adoption of the Plan is subject
to the approval of the shareholders of the Company by September 30, 1998. Any
incentive stock options granted after adoption of the Plan by the Board of
Directors will be treated as nonqualified stock options if shareholder approval
is not obtained by September 30, 1998.

CECO Filters, Inc.

         CECO Filters, Inc. ("CECO"), a Delaware corporation, is located in
Conshohocken, Pennsylvania. CECO manufactures and sells industrial air filters
known as fiber bed mist eliminators. The filters are used to trap, collect and
remove solid soluble and liquid particulate matter suspended in an air or other
gas stream whether generated in a point source emission or otherwise. The
principal functions which can be performed by use of the filters are (a) the
removal of damaging mists and particles (for example, in process operations that
could cause downstream corrosion and damage to equipment), (b) the removal of
pollutants and (c) the recovery of valuable materials for reuse. The filters are
also used to collect fine insoluble particulates. CECO's filters are used by,
among others, the printing, electronics and mining industries; metal refiners;
manufacturers of various acids, vegetable and animal based cooking oils, textile
products, alkalies, chlorine, paper, computers, automobiles, asphalt,
pharmaceutical products and chromic acid; electric generating facilities
including cogeneration facilities; and end users of pollution control products
such as incinerators.

                                        4

<PAGE>




         CECO's filters are typically cylindrical in shape. The cylinder
consists of inner and outer cylindrical cages, with filter material placed in
the gap between the cages (usually two inches wide). Prior to insertion in the
filter, raw filter material is placed in cylindrical molds and heated in an
oven. Finished filter material segments are compressed in the gap between the
cages. CECO also manufactures small vessels for holding its filters.

         CECO holds a US Patent for a device with the trade names of the
N-SERT(R) and X-SERT(R) prefilter. This device is used to protect the filter's
surface from becoming coated with insoluble solids. Field performance has
demonstrated the effectiveness of this device. CECO also holds a patent for its
N-ESTED(R) multiple-bed fiberbed TWIN-PAK(R) filter, which permits an increase
in filter surface area of 60% or more, thus decreasing energy consumption and
improving collection efficiency. The device also permits the user to increase
the capacity of the emission generating source without an energy or major
modification penalty.

         The air filters typically are mounted vertically in a closed tank with
an air inlet for dirty gas and an exhaust for clean flow. The air flow is
directed in such a manner that it passes through the outside of the filter to
the inside core, or vice versa. After being captured in the filter, liquid
particulates drain from the filter and are collected for reuse or removed, as
the case may be. Solid soluble particulates can be dissolved in water or other
suitable solvents and drained from the filter. Insoluble particles can be
removed only by gentle brushing or washing.

         CECO's filters range in size from 2 to 20 feet in height and are
typically either 16 or 24 inches in diameter. The cages used in CECO's filter
assemblies may be stainless steel, carbon steel, titanium or fiberglass mesh.
The filter material used in approximately 75% of CECO's filters is fiberglass,
which may be purchased in various grades of fiber diameter and chemical
resistance depending on the specific requirements of the customer. Filter
material may also be made of polyester, polypropelene or ceramic materials.
CECO's filters are manufactured with different levels of efficiency in the
collectibility of particulates, depending on the requirements of the customer.

         Eventually, the filter material contained in CECO's filters will become
saturated with insoluble solids or corroded and require replacement. The life of
the filter material will be primarily dependent on the nature of the particles
collected and the filtration atmosphere. Filter life generally ranges from 3
months to 15 years. The filters can be returned to CECO for replacement of the
filter material, or can be replaced on-site by the customer. CECO sells
replacement filter material segments with the trade name of SITE-PAK(R) for
on-site installation by the customer and compressor kits to be used in
connection with on-site replacement.

         A significant portion of CECO's business consists of the sale of
replacement filter material segments for its filters and for filters made by
other manufacturers. The replacement process for filters made by other
manufacturers involves modification of the cages to permit the insertion of
replacement segments. Once modification of the cage and replacement of filter
material has been completed by CECO, subsequent replacement of the filter
material can be made on-site by the customer.

                                        5

         During 1997, CECO continued to implement the results of its new design
strategies by utilizing standard components customized for specific customer
needs. These unique designs are characterized by ease of use, flexibility in
application and the ability to achieve complete product recycle when the
customer's use is satisfied. This breakthrough will enable CECO to offer the
same units or applications in widely disparate industries with the possibility
to reuse the units once the original use is satisfied. It also allows CECO the
flexibility to sell or rent the systems. The rental approach allows CECO to
reuse the units after cleaning and repacking, resulting in a high return on
capital employed.

         Air Purator Corporation ("APC"), a wholly owned subsidiary of CECO, is
engaged in the manufacture of patented specialty needled fiberglass fabrics.
Some of the fabrics are coated to permit their use in certain highly corrosive
applications. The fabrics are mainly used in a particulate collection device
known as a pulse jet baghouse which is fabricated by a number of companies.
Before APC's fabric is placed into the baghouse, the fabric will generally be
sewn into a shape resembling a tube closed at one end, called a bag. The bag is
then placed in an enclosed cylindrical apparatus known as a bag holder. APC
mainly sells its fabrics to the bag fabricator. Other applications include the
recovery of valuable materials such as carbon black. There are many domestic and
foreign fabricators with which APC deals. Products are uniformly priced for all
purchasers through a published price list. APC's flagship product line is known
in the field under the Huyglas(R) trade name. Huyglas is patented and is mainly
used for high temperature (up to 550oF) service.

         During 1996, APC developed a new, felted fiberglass fabric designed to
compete with DuPont's Nomex(R). A new, felted fiberglass fabric was developed by
APC targeted to compete with DuPont Nomex(R) and other fabrics sold for dust
collection in industrial applications. This product will allow CECO to compete
for a larger share of the global market for filter fabric media and will add to
our established position with the Huyglas(R) trade name.

         APC is presently engaged in the development of additional products
based on its patented technology. One of its sales personnel is designated as a
"Product Champion" and is vigorously pursuing various applications outside of
uses traditionally associated with such fabrics. Several new products are
currently being tested, but APC is unable to predict whether these efforts will
result in the successful development of marketable products.

          In October 1997, the assets of Compliance Systems International, a
Delaware corporation ("CSI"), a wholly-owned subsidiary of CECO, were moved to
CECO. CSI was originally formed by CECO to pursue domestic and foreign
environmental service markets and the sale of certain specialty equipment. CECO
does, however, maintain use of the name CSI in its operations.

         CSI organized the Technology Council (the "Council"), a group of
independent consultants that are available to assist on CECO's behalf, CECO's
industrial and commercial clients with environmental control options including
waste minimization. Members of the

                                        6

<PAGE>



Council are consulted by CECO when a customer hires CECO to address a problem
that CECO can not resolve and which falls within such Council member's
particular expertise.

         Through CSI, CECO has exclusive rights to engineer, market and sell the
patented Catenary Grid Scrubber(R). This device is designed for use with heat
and mass transfer operations and particulate control. CECO designs complete
systems centered around these devices.

         During the fourth quarter of 1996 CECO formed USFM. USFM provides
facilities management and emission control systems, software and outsource
monitoring and/or maintenance services to help customers achieve air quality and
operational goals. In 1997, CECO funded USFM with $400,000 to test CAMF services
in Phoenix, Arizona. This is a component in CECO's new strategy to focus on
adding additional service elements to its products.

         During 1997, there were no customers which comprised more than 10% of
CECO's consolidated net sales. During 1996 and 1995, two customers each
comprised more than 10% of CECO's consolidated net sales in each year. Because
the demand for CECO's filters, replacement segments, fabric material, scrubbers
and consulting services is not constant but can fluctuate due to economic
conditions, filter life and other factors beyond CECO's control, CECO is unable
to predict the level of purchases by its largest customers, or any other
customer, in the future.

         While CECO is exploring targeting larger industrial markets, CECO is
also continuing to service specialty market areas, where it believes it has a
competitive advantage over its larger competitors who generally have much
greater resources than CECO. In the year ended December 31, 1997, CECO and its
subsidiaries continued to develop additional market areas, including storage
facility and turbine lube oil vent emission control and their related odor
control, new dry particulate emission control and combination scrubber - fiber
bed filter systems, while also implementing changes to reach larger industrial
markets. In recent years CECO added capabilities to penetrate the semiconductor
and printed circuit board markets through its filter technology and its patented
scrubbers.

         CECO has not been materially impacted by existing government
regulation, nor is CECO aware of any probable government regulation that would
materially affect its operations. CECO's costs in complying with environmental
laws has been negligible. During 1997 and 1996, CECO estimates that $91,803 and
$116,979, respectively, has been expended on research and development programs.
Such costs are generally included as factors in determining CECO's pricing
procedures.

         Suppliers

         CECO purchases all of its chemical grade fiberglass as needed from
Manville Corporation, which CECO believes is the only domestic supplier of such
fiberglass. However, there are foreign suppliers of chemical grade fiberglass,
and, based on current conditions, CECO

                                        7

<PAGE>



believes that it could obtain such material from foreign suppliers on acceptable
terms. CECO believes that there is sufficient supply of raw materials for the
other components of its filters and does not anticipate any shortages in the
near future.

         APC purchases its raw material from a variety of sources and does not
anticipate any shortages in the near future. While CECO depends upon two
suppliers for certain specialty items, including glass and chemicals, CECO
believes it has a good relationship with such suppliers and does not anticipate
any difficulty in continuing to receive such items on terms acceptable to CECO.

         Busch purchases a majority of its fans from New York Blower and a
majority of its louvers from American Warming. Busch purchases additional
materials from a variety of sources and does not anticipate any shortages in the
near future. Busch believes it has a good relationship with such suppliers and
does not anticipate any difficulty in continuing to receive such items on terms
acceptable to Busch.

         Backlog

         As of December 31, 1997, CECO's backlog of orders was approximately
$10,213,816, as compared to approximately $3,700,000 as of December 31, 1996.

         Competition and Marketing

         Monsanto Corporation is dominant in the fiber bed mist eliminator
industry. Monsanto's financial resources are far greater than CECO's, and
Monsanto can undertake much more extensive marketing and advertising programs
than CECO. Monsanto is also a competitor of Busch. Certain other competitors
also have greater financial resources than CECO.

         CECO competes by stressing its exclusive products, including
SITE-PAK(R) segments that permit on-site filter media replacement capability and
prefilters, its patented product that protects the surface of a fiber bed filter
from becoming plugged with solids, and its patented multiple-bed fiberbed
filters that dramatically increase the surface area of a filter. Also, CECO
believes that it is the only U.S. manufacturer of fiber bed mist eliminators
whose filter material can be replaced on-site by a customer. CECO believes it is
price competitive within the market for filters with similar efficiency.

         Manufacturers of electrostatic precipitators and wet scrubbers may also
be deemed to be in competition with CECO, because those devices are also
effective in removing particulates from an air or another gas stream. While such
devices may have higher operating costs than fiber bed mist eliminators,
replacement of the component parts of such devices is rare as compared to fiber
bed mist eliminators.

         CECO's subsidiaries each face substantial competition. Kirk & Blum is
dominant in the air systems design industry and competes with Busch
International, a division of Busch. Kirk

                                        8

<PAGE>



& Blum's financial resources are far greater than CECO's. APC and CSI each face
competition from other forms of environmental control and material recovery
devices including scrubbers and electrostatic precipitators and from other
filter fabric media that can also be fabricated into bags for baghouses. These
fabrics and fibers include, Teflon(R), Goretex(R), woven fiberglass (both
treated and non-treated), polyester, Ryton(R), Nomex(R) and several other
fabrics.

          CECO's marketing efforts have consisted of telemarketing and direct
solicitation of orders from existing customers. CECO is also utilizing direct
mail solicitation and selected advertising in trade journals and product guides
and trade shows. CECO also utilizes sales representatives located in the United
States, Canada and overseas and Special Sales Directors, each focused on
specific industries. Busch, in addition to using direct solicitation and some
sales representatives, also participates in industrial shows.

         Employees

         As of March 17, 1998, the Company did not have any full-time employees.
CECO and its subsidiaries had 78 full-time employees and 3 part-time employees
as of December 31, 1997. None of CECO's employees is currently unionized and
CECO considers its relationship with its employees to be satisfactory.

         Key Employee

         CECO's operations to date have been largely dependent on the efforts of
its President, Dr. Steven I. Taub. The loss to CECO of Dr. Taub would have a
material adverse effect upon the operations of CECO. CECO has obtained key man
life insurance in face amount of $5 million on the life of Dr. Taub in an effort
to reduce, to the extent possible, the immediate adverse economic impact to its
business that would occur if it were to lose the services of Dr.
Taub.

         Product Liability Insurance
 
         As of October, 1989 CECO obtained product liability insurance covering
its products. The policy excludes environmental liability.

         Patents
 
         CECO currently holds one US patent for its N-SERT(R) and X-SERT(R)
prefilters. CECO also holds a patent on its N-ESTED(R) multiple bed fiberbed
filter and an exclusive world-wide license to the patent on the Catenary Grid
Scrubber and the Narrow Gap Venturi Scrubber. APC holds two patents on the
Huyglas material. All of the prefilters, the multiple bed units and the Huyglas
material have contributed to CECO's performance during 1997. Busch holds an
exclusive license to the patent on the JET*STAR strip cooler, strip dryer, coil
cooler, and strip blow-off systems. Busch also holds an exclusive license on the
patent on the flexible nozzle material used in connection with the JET*STAR
systems and the process of using water in

                                        9

<PAGE>



addition to air used in the JET*STAR systems. There is no assurance that
measurable revenues will accrue to CECO or its subsidiaries as a result of their
patents or licenses.

         New Busch Co., Inc.

         CECO purchased the business of Busch Co. in September of 1997. Busch
Co. had been in business since August of 1947.

         Busch is engaged in the business of marketing, selling, designing and
assembling ventilation, environmental and process-related products, and
providing manufacturer's representative services to certain companies or
manufacturers in support or related businesses. Busch consists of three
divisions: Busch INTERNATIONAL, Busch MARTEC, and Busch RIG (resource
implementation group).

         Busch INTERNATIONAL, the largest division of Busch, designs and
supplies custom air systems to steel, aluminum, chemical, paper, glass, cement,
power generation, and related industries on an international level. As part of
its system designs, it supplies custom engineered precision-manufactured
products specializing in air related applications. In addition, Busch
INTERNATIONAL provides a wide range of special services, including conceptual
studies, application engineering, and system start-up. Busch employs an
engineering staff experienced in aerodynamic, mechanical, civil, and electrical
disciplines. These personnel are utilized entirely to support Busch's air
systems work. Areas of expertise include turbine inlet filtration, evaporative
cooling, gas absorption, scrubbers, acoustics, and corrosion control.

         Busch INTERNATIONAL is noted as the premier supplier of custom
engineered solutions for the control of fume and oil mist emissions from steel
and aluminum rolling mills. Busch's Fume-Shield Systems are designed and
supplied by Busch and are devised to contain, capture, convey, and clean
contaminated air. Busch International fume exhaust systems and air- curtain
hoods are designed to provide high efficiency control of oil mist and fumes.

         Busch INTERNATIONAL also designs, manufactures and supplies ventilation
and other air handling equipment for industrial use. It also provides systems
for corrosion protection, fugitive emissions control, evaporative cooling, oil
mist collection, mill building ventilation, crane cab ventilation and other air
handling applications. Some of these air handling units are the MRV-80, MRV-81,
N-DUR-AIR, RE-TREAT,(R) and PCR.

         Busch INTERNATIONAL'S Jet*Star strip cooler, strip dryer, coil cooler,
and strip blow- off systems are gaining significant market penetration for the
ability to rapidly cool metal. The rapid cooling permits higher throughput than
competitive processes. Busch is presently involved in supplying Jet*Start for
new and upgrade mill construction work.

         Busch MARTEC acts as a manufacturers' representative with manufacturers
relating to air and fluids products. Busch MARTEC does business almost
exclusively in the Pittsburgh and tri-state area. Busch MARTEC also supplies
certain products to the other Busch divisions.

                                       10

<PAGE>




         Busch RIG (resource implementation group) was started in November 1996.
It designs and manufactures custom electrical and control systems and also acts
as a manufacturers' representative of certain products, such as heat transfer
devices and related support products.

         Recent Acquisitions

         On September 25, 1997, pursuant to an Asset Purchase Agreement, New
Busch Co., Inc., a Delaware corporation ("Busch") which is a wholly-owned
subsidiary of CECO formed on June 19, 1997, acquired certain assets, and all
rights and interests of, Busch Co., a Pennsylvania corporation (the "Seller")
for a purchase price of $2,100,000 plus acquisition costs. CECO financed the
acquisition with proceeds from (i) a $1,040,576 loan from CECO's secured
line-of-credit from CoreStates Bank, N.A., with an interest rate of 1/2% over
the bank's prime lending rate, (ii) a secured term loan in the amount of
$1,000,000 from CoreStates Bank, N.A. with an interest rate of 8.75% per annum,
and (iii) a subordinated, unsecured loan from the Company in the amount of
$500,000 with an interest rate of 10% per annum. The Seller was engaged in the
business of marketing, selling, designing and assembling ventilation,
environmental and process-related products, and also provided manufacturer's
representative services to certain companies or manufacturers in support or
related businesses.

         Acquisition of Shares of CECO by the Company
 
         In June, 1997, the Company exchanged 186,000 additional shares of its
common stock for 186,000 shares of CECO's common stock with unrelated third
parties. On August 13, 1997, pursuant to an Agreement and Plan of Reorganization
among the Company, CECO and Stephen Taub, the Company exchanged 582,500 shares
of its common stock for 1,165,000 shares of CECO's common stock with Dr. Taub.
Such transaction was intended to qualify as a "B" reorganization pursuant to the
Internal Revenue Code.

         In addition, on February 18, 1998, the Company exchanged 281,768 shares
of the Company for 281,768 shares of CECO with a single off-shore investor,
which brought the Company's ownership of CECO's stock to 6,274,498 shares,
representing 91.36% of CECO's outstanding common stock.

         The Company intends to purchase additional shares of CECO common stock
if such additional shares become available at a price which the Company
considers reasonable. Such purchases, if made, would be made through private
transactions, including exchanges of the Company's common stock for CECO common
stock, or open market stock purchases of CECO common stock.

         Investment by CECO in the Company
 
         On May 26, 1993, CECO purchased 100,000 shares of newly issued Common
Stock of the Company for $2.80 per share or $280,000 in the aggregate. The
market price for the Company's Common Stock closed at $4.00 per share at that
date. The purchase price was paid

                                       11

<PAGE>



for with $160,000 in cash, with the balance due on demand, without interest. The
balance was paid in full during the first quarter of 1994. On the date of
purchase the Company owned 52.1% of CECO's common stock. As of December 31,
1997, CECO distributed 17,800 shares of such Common Stock of the Company to
certain of CECO's key employees in lieu of cash bonuses. Such CECO employees are
restricted from selling such Common Stock for one year from the date of
distribution.


Item 2.  Properties

         The Company maintains its offices in Toronto, Ontario at premises made
available to them at no charge by Phillip DeZwirek, the Chief Executive Officer,
Chief Financial Officer, Chairman of the Board of Directors and a controlling
shareholder of the Company.

         CECO owns a plant facility in Conshohocken, Pennsylvania. On February
25, 1993 CECO refinanced the property with a fourteen year commercial mortgage
from CoreStates Bank at 8% through March 1, 1998 and thereafter at 3/4% over the
Bank's prime rate.

         APC leases 11,500 square feet of space from BTR North America, Inc. for
the premises in Taunton, Massachusetts for annual rental of $54,625. This lease
expires on February 28 of each year and is renewable yearly upon mutual consent
and APC continues to lease the premises as a tenant-at-will.

         CECO leases approximately 1,418 square feet at an annual rental of
$13,201.58 in California, which space was used by CSI and is now used by CECO.

         Busch maintains its offices in Pittsburgh, Pennsylvania. The lease that
Busch was assigned in connection with the acquisition of the Busch assets, is
dated January 10, 1980 and extends through July 1999. The lease is for
approximately 12,000 square feet at an annual rental of $133,308. Andrew M.
Halapin, the former principal owner of Busch, is the beneficial owner of the
property in which Busch's offices are located. Busch also leases 1,000 square
feet of space in Etna, Pennsylvania for $315 per month. Such lease will expire
on March 31, 1999.

Item 3.  Legal Proceedings

         There are no material pending legal proceedings to which the Company or
any of its subsidiaries is a party or to which any of their property is subject.

Item 6.  Management's Discussion and Analysis or Plan of Operation.
 
Financial Condition, Liquidity and Capital Resources

The Company's consolidated cash position increased from $412,174 on December 31,
1996 to $847,827 on December 31, 1997. This net increase is attributable
principally to the increase in cash provided by operating activities of
$2,060,468 and the increase in cash provided by financing activities of
$946,937, offset by cash used in investing activities of $2,571,752. Cash
provided from operating activities includes cash received in connection with
progress billings related to engineering contracts negotiated by New Busch Co.
The Company acquired

                                       13

<PAGE>



substantially all of the assets of Busch Co. in September 1997. Busch, located
in Pittsburgh, Pennsylvania, is engaged in the business of marketing, selling,
designing and assembling ventilation, environmental and process related products
and also provides manufacturer's representative services to certain companies or
manufacturers in support or related businesses.

At December 31, 1997, the Company's consolidated working capital was $648,756
compared to $2,187,596 at December 31,1996. A principal reason for the reduction
in working capital is the result of the liability associated with the progress
billing described previously. The investments in marketable securities, which
earned interest income of $84,326 in 1997, are primarily in high yield bonds of
major U.S. corporations.

CECO's capital expenditures amounted to $210,087 and $78,720 for the years ended
December 31, 1997 and 1996, respectively. Such expenditures were primarily for
computer hardware and software upgrades, engineering and manufacturing equipment
upgrades and office renovations. CECO does not have material firm commitments
for capital expenditures. However, equipment expenditure requirements are
expected to increase as a result of CECO's anticipated growth.

CECO increased its line of credit with a commercial bank from $1,250,000 to
$1,500,000, of which none was outstanding as of December 31, 1997. However, CECO
also entered into a four- year, $1,000,000 term loan, with the same bank, the
proceeds of which were used towards the acquisition of Busch described
previously. At December 31, 1997, the principal outstanding balance on the term
loan was $937,500.

The Company and CECO entered into a five-year management and consulting
agreement, dated January 1, 1994 pursuant to which the Company provides
management and financial consulting services to CECO for a monthly fee of
$20,000 until the agreement expires in December 1998.

The Company believes its consulting agreement with CECO and interest income from
its investments in marketable securities should provide sufficient revenue to
meet its general and administrative expenses. Management believes that CECO's
expected cash flow from operations, supplemented by the available line of
credit, will be adequate to meet CECO's anticipated cash needs for working
capital, revenue growth, scheduled debt repayment and capital investment
objectives for at least the next twelve months.

Results of Operations - The Company

The Company's consolidated statement of operations for the years ended December
31, 1997 and 1996 reflect the operations of the Company consolidated with the
operations of CECO. During 1997, the Company earned consulting fees from CECO
($240,000), earned investment income from marketable securities ($84,326) and
continued to incur general and administrative expenses ($204,104). As of
December 31, 1997, the Company owned approximately 87.5% of the outstanding
Common Stock of CECO. Minority interest on the consolidated statement of
operations has been presented as a reduction in the loss for the year.

Results of Operations - The Company (continued)

The Company's consolidated net sales, comprised entirely of CECO's consolidated
net sales, were $14,530,974 for the year ended December 31, 1997 and $9,847,697
for the year ended December 31, 1996, an increase of 47.6%. This increase was
due primarily to the sales of Busch.

Selling and administrative expenses were $204,104 for the year ended December
31, 1997 and $208,018 for the year ended December 31, 1996, excluding those
expenses incurred by CECO that are reflected on the Company's consolidated
statement of operations. Those expenses included accounting and legal fees, and
fees relating to acquisition consulting and shareholder relations.

The Company received $240,000 for each of the years ended December 31, 1997 and
1996 for management and financial consulting services provided to CECO. This
amount is not reflected in the consolidated results of operations since it is
eliminated in consolidation.

Except as set forth above, the Company has no other income (loss), revenues or
expenses other than as a result of its investment in CECO and investment in
marketable securities. The Company does not engage in operations other than
through its operating subsidiary CECO. See discussion of CECO herein.

Results of Operations - CECO

1997 as Compared to 1996

Revenues for the year ended December 31, 1997 were $14,530,974, an increase of
$4,683,277 or 47.6% from $9,847,697 for the year ended December 31, 1996. This
increase was due primarily to the Busch acquisition completed in 1997.

CECO's overall cost of sales increased as a percentage of sales for the year
ended December 31, 1997 (55.8%) compared to the year ended December 31, 1996
(52.7%). This increase is attributed to the impact of the Busch acquisition;
Busch's costs as a percentage of sales amounted to 66.9% from July 1, 1997
through December 31, 1997. Without the acquisition of Busch, CECO's cost of
sales as a percentage of sales would have been 51.0%. The decrease compared to
the prior year, excluding figures from the operations of Busch, is attributed to
lower material costs, as well as lower costs incurred to service CECO's
products. CECO continues to use the latest technology available in an effort to
reduce both cost of sales, including maintaining optimal levels of inventory and
operating expenses, and ultimately increase overall company profits.

CECO's selling and administrative expenses amounted to $5,850,452 for the year
ended December 31, 1997 compared to $3,316,716 for the year ended December 31,
1996, representing an increase of $2,533,736, or 76.4%. A significant amount of
this increase is attributable to (i) selling and administrative expenses of
Busch's operations since the effective date of the Busch

                                       16

<PAGE>



acquisition, and (ii) selling and administrative expenses associated with USFM
which only recently commenced its operations. The selling and administrative
expenses of Busch include a non-recurring $500,000 charge for a sign-on bonus
(the "Sign On Bonus") paid to a former officer of the old Busch Co. in
connection with a three-year employment agreement. A substantial portion of
CECO's selling and administrative expenses are fixed in nature.

CECO entered into a management and consulting agreement with the Company in
1994, in which terms of the agreement require payment of monthly fees of $20,000
through December 1998 in exchange for management and financial consulting
services involving corporate policies; marketing; strategic and financial
planning; and mergers, acquisitions and related matters. CECO paid management
fees to the Company of $240,000 during each of the years ended December 31, 1997
and 1996.

CECO's depreciation and amortization expense decreased from $341,599 in 1996 to
$289,544 in 1997, primarily because equipment and intangible assets acquired
more than five years ago became fully amortized or depreciated during 1997.

CECO's interest expense decreased by $24,136 or 15.6% during the year ended
December 31, 1997 compared to the same period in 1996, principally due to
decreased borrowings from CECO's line of credit in 1997.

CECO incurred a pretax loss of $95,744 for the year ended December 31, 1997
compared to pretax income of $606,813 for the year ended December 31, 1996.
Pretax income for the year ended December 31, 1997, before deducting the charge
for the Sign On Bonus ("non-recurring charge"), was $404,256. The decrease from
the prior year is attributed principally to the increase in selling and
administrative expenses in relation to the Busch acquisition, expenses connected
with the start-up of USFM and expenses in relation to international sales
development.

Net income (loss) per share for 1997 and 1996 before and after non-recurring
charges were as follows:

                                           1997      1996

After non-recurring charge                 (.01)      .06

1996 as Compared to 1995

      CECO's consolidated net sales increased by $1,412,388 or 16.7% from
      $8,435,309 in 1995 compared to $9,847,697 in 1996. Net income increased in
      1996 from a loss of ($71,241) or ($0.01) per share to earnings of $401,025
      or $0.07 per share in 1996, an improvement of $472,266. This dramatic
      improvement in financial performance was attributed to:


                                       17

<PAGE>



      o  Continuation of CECO's target market strategy which allowed CECO to
         improve gross profit margins by attaining higher value for the products
         and services CECO provides.

      o  Repositioning CECO in the marketplace to enhance how CECO is viewed by
         customers, competitors, employees, and shareholders. CECO is making
         good progress in identifying market segments that fit criteria for
         delivering exceptional value to both its customers and shareholders.

      o  Redirection of CECO's design strategies to utilize standard components
         customized for specific customer needs. This specialized
         standardization approach helped shape much of CECO's new developments
         in 1996, and will become the cornerstone for improving competitiveness
         and profit margins over the next several years.

      o  A new subsidiary, USFM, was formed to implement CECO'S facilities
         management strategy. Investment in this new activity was nearly
         $200,000. The market potential of this service-oriented business could
         greatly exceed that of the existing businesses and is discussed
         subsequently.

      o  Research and development expenditures in 1996 were increased from
         $17,484 in 1995 to $116,979 in 1996 and resulted in the following
         developments:

         Two patent applications directed toward enhancing CECO's customized
         standardization (CS) strategy. These unique designs are characterized
         by ease of use, flexibility in application and the ability to achieve
         complete product recycle when the customer's use is satisfied. This
         breakthrough will enable CECO to offer the same units or applications
         in widely disparate industries with the possibility to reuse the units
         once the original use is satisfied. It also allows CECO the flexibility
         to sell or rent the systems. The rental approach allows CECO to reuse
         the units after cleaning and repacking, resulting in a high return on
         capital employed.

         A new, felted fiberglass fabric was developed by CECO's APC subsidiary,
         targeted to compete with DuPont Nomex(R) and other fabrics sold for
         dust collection in industrial applications. This product will allow
         CECO to compete for a larger share of the global market for filter
         fabric media and will add to CECO's established position with the
         Huyglas(R) trade name.

CECO's cost of sales as a percentage of sales decreased by 3.4% in 1996 from
56.1% in 1995 compared to 52.7% in 1996. The decrease was due primarily to
decreased raw material costs.

Selling and administrative expenses increased by $265,899 from $3,050,817 in
1995 to $3,316,716 in 1996. Approximately $200,000 of such increase was
attributed to CECO's investment in the facilities management strategy described
previously. CECO's

                                       18

<PAGE>



selling and administrative expenses decreased by 2.5%, as a percentage of sales,
from 36.2% in 1995 to 33.7% in 1996. A substantial portion of the selling and
administrative expenses are fixed in nature.

CECO's depreciation and amortization expense decreased slightly from $356,634 in
1995 to $341,599 in 1996 primarily due to a decrease in equipment acquisitions
in 1996.

CECO's interest expense decreased from $175,028 in 1995 to $154,837 in 1996,

                          INDEPENDENT AUDITOR'S REPORT



To the Board of Directors and Shareholders
CECO Environmental Corp. and Subsidiaries
Toronto, Ontario Canada

We have audited the accompanying consolidated balance sheet of CECO
Environmental Corp. and Subsidiaries as of December 31, 1997 and 1996, and the
related consolidated statements of operations, shareholders' equity, and cash
flows for the years then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of CECO Environmental Corp. and
Subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for the years then ended in conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996
- --------------------------------------------------------------------------------



1.      Nature of Business and Summary of Significant Accounting Policies

        Nature of business - The principal business of the Company's subsidiary
        is to provide standard and engineered systems for air quality
        improvement and to offer complete operation, maintenance and data
        processing services to industrial and commercial customers, primarily in
        the United States.

        Principles of consolidation - The consolidated financial statements
        include the accounts of CECO Environmental Corp. (the "Company"), and
        CECO Filters, Inc. ("CFI"), an 87.5% (as of December 31, 1997) owned
        subsidiary. The Company acquired its majority ownership in CFI in April
        1993 (see Note 2). All intercompany balances and transactions have been
        eliminated.

        Use of estimates - The presentation of financial statements in
        conformity with generally accepted accounting principles requires
        management to make estimates and assumptions that affect the reported
        amounts of assets and liabilities and disclosure of contingent assets
        and liabilities at the date of the financial statements and the reported
        amounts of revenues and expenses during the reporting period. Actual
        results could differ from those estimates.

        Investments in marketable securities - The Company's investments in
        marketable securities comprise corporate debt securities, all classified
        as trading securities, which are carried at their fair value based on
        the quoted market prices. Accordingly, net realized and unrealized gains
        and losses on trading securities are included in net income.
        Investment income consists principally of interest income.

        Accounts receivable - The Company considers accounts receivable to be
        fully collectible; accordingly, no allowance for doubtful accounts is
        required.

        Inventories and revenue recognition - Inventories are valued at the
        lower of cost, using the first-in, first-out (FIFO) method, or market.

        Property and equipment - Property and equipment are recorded at cost.
        Expenditures for repairs and maintenance are charged to income as
        incurred. Depreciation is computed using the straight-line method over
        the estimated useful lives of the assets.

        Intangible assets - Goodwill is being amortized on a straight-line basis
        over 40 years. The Company's policy is to continually monitor the
        recoverability of goodwill using a fair value approach. Other intangible
        assets are being amortized on a straight-line basis over their estimated
        useful lives, which range from 5 to 17 years.

        Revenue recognition - Revenue from manufactured products and products
        purchased for resale is recognized upon shipment to customers.

        Revenue from contracts for the design and manufacture of air handling
        units are recognized on the percentage of completion method, measured by
        the percentage of contract costs incurred to date to estimated total
        contract costs for each contract. This method is used because management
        considers contract costs to be the best available measure of progress on
        these contracts.

1.      Nature of Business and Summary of Significant Accounting Policies - 
        Continued

        Contracts - continued

        Contract costs include direct material, labor cost and those indirect
        costs related to contract performance, such as indirect labor, supplies,
        tools and repairs. Selling and administrative costs are charged to
        expense as incurred. Provisions for estimated losses on uncompleted
        contracts are made in the period in which such losses are determined.
        Changes in job performance, job conditions and estimated profitability
        may result in revisions to contract revenue and costs and are recognized
        in the period in which the revisions are made.

        The asset, "costs and estimated earnings in excess of billings on
        uncompleted contracts," represents revenues recognized in excess of
        amounts billed. The liability, "billings in excess of costs and
        estimated earnings on uncompleted contracts," represents billings in
        excess of revenues recognized.

        Advertising costs - Advertising costs are charged to operations in the
        year incurred and totaled $117,481 in 1997 and $130,762 in 1996.

        Research and development - Research and development costs are charged to
        expense as incurred. The amounts charged were $91,803 in 1997 and
        $116,979 in 1996.

        Per share data - The Company adopted Statement of Financial Accounting
        Standards ("SFAS") No. 128, "Earnings per Share" which establishes
        standards for computing basic and diluted earnings per share and is
        effective for periods ending after December 15, 1997. Per share data is
        computed using the weighted average number of common shares outstanding.
        The Company considers outstanding options and warrants in computing
        diluted net income (loss) per share only when they are dilutive. The
        weighted average number of common shares was 7,551,836 for 1997 and
        7,001,036 for 1996 for basic and 7,953,212 for 1997 and 7,001,036 for
        1996 diluted net income (loss) per share.

        Reclassifications - Certain reclassifications have been made to the 1995
        financial statements to conform with the 1996 presentation.

        Stock-based compensation - In October, 1996, the Financial Accounting
        Standards Board adopted Statement of Financial Accounting Standards
        ("SFAS") No. 123, "Accounting for Stock-Based Compensation. SFAS 123
        permits companies to choose between a "fair value based method of
        accounting" for employee stock options or to continue to measure
        compensation cost for employee stock compensation plans using the
        intrinsic value based method of accounting prescribed by Accounting
        Principles Board Opinion No. 25, "Accounting for Stock Issued to
        Employees" ("APB 25"). The Company has chosen to continue to use the APB
        25 method. Under such method, compensation is measured by the quoted
        market price of the stock at the measurement date less the amount, if
        any, that the employee is required to pay. The measurement date is the
        first date on which the number of shares that an individual employee is
        entitled to receive and the option or purchase price, if any, are known.
        The Company did not incur any compensation expense related to its or
        CFI's stock option plan or the Company's warrants during 1997 and 1996.

1.      Nature of Business and Summary of Significant Accounting Policies -
        Continued

        Stock-based compensation - continued

        Entities electing to remain with this method must make pro forma
        disclosures of net income (loss) and earnings (loss) per share as if the
        fair value based method of accounting defined in SFAS 123 had been
        applied to all awards granted in fiscal years beginning after December
        15, 1994. Had compensation cost for its or CFI's stock option plan and
        the warrants issued by the Company been determined based on the fair
        value at the grant dates for awards under those arrangements consistent
        with the method of SFAS 123, the Company's 1996 net income and earnings
        per share would have been reduced to $38,583 and $.01, respectively. The
        effect on net loss for 1997 for options granted under the Company's
        stock option plan would have been de minimis.

        Changes in accounting policies - In June, 1997, the FASB issued SFAS No.
        130, "Reporting Comprehensive Income," and SFAS No. 131, "Disclosures
        about Segments of an Enterprise and Related Information". In February,
        1998, the FASB also issued SFAS No. 132, "Employer's Disclosures about
        Pensions and Other Postretirement Benefits". These pronouncements are
        effective for fiscal years beginning after December 15, 1997, and thus
        do not effect any of the financial statements reported on herein, but
        will become effective in 1998. The adoption of these pronouncements will
        have no impact on the Company's consolidated results of operations,
        financial position, or cash flows, but upon adoption may require
        disclosures for prior periods to be restated.



2.      Investment in CFI/Goodwill

        Pursuant to a Stock Exchange Agreement dated May 30, 1992, between the
        Company and IntroTech Investments, Inc. ("IntroTech"), a privately-held
        Ontario corporation, the Company exchanged 1,666,666 newly issued shares
        of its common stock for 1,666,666 shares of CFI common stock owned by
        IntroTech. CFI is a publicly-held Delaware corporation. The 1,666,666
        shares of CFI common stock acquired by the Company are restricted. Those
        shares represented 24.51% of the outstanding shares of common stock of
        CFI.

        During 1993 through 1996, the Company exchanged 2,953,964 additional
        shares of its common stock for 2,953,964 shares of CFI's common stock
        with unrelated third parties. Also, during 1993, the Company acquired,
        for cash, an additional 21,100 shares of CFI's common stock from
        unrelated third parties, which were subsequently sold in September,
        1997. In June, 1997, the Company exchanged 186,000 additional shares of
        its common stock for 186,000 shares of CFI's common stock with unrelated
        third parties. On August 13, 1997, the Company exchanged 582,500 shares
        of its common stock for 1,165,000 shares of CFI's common stock with an
        officer of CFI. As of December 31, 1997, the Company owned 87.5% of
        CFI's common stock.

        The Company included CFI and its wholly-owned subsidiaries in its
        consolidated financial statements as of April 1993 when the Company's
        ownership of CFI's common stock exceeded 50%.

3.      Acquisition of Business

        On September 25, 1997, pursuant to an Asset Purchase Agreement, New
        Busch Co., Inc., a wholly-owned subsidiary of CECO Filters, Inc.,
        acquired substantially all of the assets, and the business, of Busch Co.
        ("Busch") for $2,100,000 in cash, plus acquisition costs. Busch, located
        in Pittsburgh, Pennsylvania, was engaged in the business of marketing,
        selling, designing and assembling ventilation, environmental and
        process-related products, and also provided manufacturer's
        representative services to certain companies or manufacturers in support
        or related businesses. The acquisition was accounted for as a purchase.
        The excess of the aggregate purchase price over the fair market value of
        the net assets acquired of $1,819,331, which was allocated to goodwill
        based upon preliminary estimates of fair value, is being amortized over
        40 years. The Asset Purchase Agreement provides that, notwithstanding
        the actual September 25, 1997 closing date, the closing was deemed to be
        effective as of July 1, 1997. The 1997 statement of operations,
        therefore, includes the operations of New Busch Co. since July 1, 1997.

        On a pro forma basis, unaudited results of operations for the years
        ended December 31, 1997 and 1996 would have been as follows, if the
        acquisition had been made as of January 1, 1996:

4.      Financial Instruments - Continued

        Valuations for marketable securities are determined based on quoted
        market prices and valuations for long-term debt are determined based on
        future payments discounted at current interest rates for similar
        obligations.

        Management of the Company does not expect any losses to result from its
        standby letter of credit described in Note 10 and, therefore, is of the
        opinion that the fair value of this off- balance sheet financial
        instrument is zero.

        The Company does not hold any financial instruments for trading
        purposes.



        Concentrations of credit risk:

        Financial instruments that potentially subject the Company to credit
        risk consist principally of cash and accounts receivable. The Company
        performs periodic evaluations of the financial institutions in which its
        cash is invested. The Company performs ongoing credit evaluations of its
        customers' financial condition, and generally requires no collateral
        from its customers.

        CFI's property and equipment, accounts receivable, and inventory serve
        as collateral for its bank debt. The bank debt is also subject to
        financial covenants which require CFI to maintain a minimum cash flow
        coverage, current ratio and net worth. The Company obtained a waiver
        from the bank for these covenants which is effective through December
        31, 1998.

11.     Capital Lease Obligation

        CFI acquired equipment under the provisions of a long-term lease. Future
        minimum lease payments under the capital lease are as follows:

12.     Shareholders' Equity

        Stock Option Plan

        CFI maintained a stock option plan for its employees through 1996.
        During 1997, all participants in the CFI plan were given the opportunity
        to exchange their unexercised options for the same number of options in
        a new plan established by CECO Environmental Corp. Under the former
        plan, options to purchase 500,000 shares of CFI's common stock were
        available to be granted at not less than 100% of the market price of the
        shares on the date of grant. Options were generally exercisable one year
        from the date of grant and expired between five and ten years of the
        date of grant. At December 31, 1997, there were no outstanding options
        with respect to the CFI plan. Options under the 1997 CECO Environmental
        Corp. plan have the same terms. The grant date for all of the exchanged
        options is December 15, 1997, and 1,500,000 shares of CECO Environmental
        Corp.'s common stock have been reserved for issuance under this plan.

        The status of both stock option plans is as follows:

16.     Income Taxes - Continued

        The Company has federal net operating loss carryforwards of
        approximately $125,000 which expire in 2008.

        The change in valuation allowance reflects current utilization of net
        operating loss carryforwards. A valuation allowance is provided since
        the utilization of tax benefits of net operating loss carryforwards is
        not assured.

        CECO Environmental Corp. and CFI each file separate federal income tax
        returns. In addition, the federal net operating loss carryforwards are
        not available to offset taxable income of CFI.

18.     Related Party Transactions

        Effective January 1, 1995, the Company entered into a consulting
        agreement with CFI. The terms of the agreement require monthly fees by
        CFI of $20,000 through December, 1998 in exchange for management and
        financial consulting services involving corporate policies; marketing;
        strategic and financial planning; and mergers, acquisitions and related
        matters. CFI paid the Company $240,000 during each of the years ended
        December 31, 1997 and 1996. These fees have been eliminated in
        consolidation.


19.     Consulting Agreement

        The Company entered into an eighteen-month consulting agreement with an
        unrelated third party, effective April 1, 1995, to provide financial
        consulting services to the Company which would, among other things, help
        the Company to broaden its stock market appeal. As compensation, the
        consultant received an option to purchase 1,000,000 shares of the
        Company's common stock at $2.50 per share, such option expiring April
        30, 1996. Options exercised on or prior to December 31, 1995 were
        exercisable at $2.25 per share. In addition, the Company issued 100,000
        shares of its common stock to the consultant.


        The value of the options and shares issued, as determined by an
        unrelated third party, was $150,000, such amount being deferred and
        amortized over the eighteen-month period of the consulting agreement.
        Amortization of $75,000 was recorded during 1996.

        During the year ended December 31, 1996, the consultant exercised
        options to acquire 11,000 shares of the Company's common stock.

Item 10.  Executive Compensation

          Except for the compensation described below, neither the Company nor
any of its subsidiaries paid, set aside or accrued any salary or other
remuneration or bonus, or any amount pursuant to a profit-sharing, pension,
retirement, deferred compensation or other similar plan, during its last fiscal
year, to or for any of the Company's executive officers or directors.

          The directors of the Company received no consideration for serving in
their capacity as directors of the Company during its last fiscal year. The
Company has no annuity, pension or retirement plans.

Warrants

          On January 14, 1998, in consideration for Philip DeZwirek's valuable
service to the Company as an employee, officer and director, the Company granted
Mr. DeZwirek warrants (the "Warrants") to purchase up to 250,000 shares of the
Company's common stock ("Warrant Shares"). The Warrants are exercisable at any
time between June 14, 1998 and January 14, 2008 inclusive at a price of $2.75,
the closing price of the Company's common stock on January 14, 1998. The
Warrants are transferable and grant the holders thereof "piggyback registration
rights", i.e. the right to participate in any registration of securities by the
Company other than a registration statement in connection with a merger or
pursuant to registration statements on Forms S-4 or S-8. Additionally, the
holders of a majority of the Warrant Shares and the Warrants have the right on
two occasions to have the Company prepare and file with the Securities and
Exchange Commission a registration statement and such other documents as may be
necessary for such holders to effect a public offering of Warrant Shares
previously issued or to be issued upon the effectiveness of such registration
statement. The Company is however required to pay the expenses of only one of
such registrations. The right to demand such registrations expires on January
14, 2008 or upon the happening of certain other conditions.


Compensation

          On October 1, 1997, the Board of Directors of the Company adopted the
CECO Environmental Corp. 1997 Stock Option Plan (the "Plan"). The stock options
are intended to qualify as incentive stock options and may be issued to
officers, employees, directors, and consultants of the Company and its
subsidiaries. The Plan must be administered by a committee of at least two
non-employee directors; the committee currently consists of Jason DeZwirek and
Josephine Grivas. One Million, Five Hundred Thousand shares of the Company's
stock has been reserved for issuance pursuant to the Plan. Options to purchase
stock may be granted at not less than 100% of the market price of the shares on
the date of the grant, except that if the grantee of the options owns more than
10% of the voting power of stock of the Company or any of its subsidiaries, the
option price per share may not be less than 110% of the market price on the date
of the grant. As of March 18, 1998, 313,320 options under the Plan have been
issued, none of which were issued to an officer or director of the Company.
Adoption of the Plan is

                                       42

<PAGE>



subject to the approval of the shareholders of the Company by September 30,
1998. Any incentive stock options granted after adoption of the Plan by the
Board of Directors will be treated as nonqualified stock options if shareholder
approval is not obtained by September 30, 1998.

          During 1997 CECO's stock option plan was terminated and all
participants in CECO's stock option plan exchanged their options for options
pursuant to the Plan.

          The following table summarizes the total compensation of Phillip
DeZwirek, the Chief Executive Officer of the Company, for 1997 and the two
previous years. There were no other executive officers of the Company who
received compensation in excess of $100,000 in 1997.

          (c)     Changes in Control

          The Company is not aware of any current arrangement(s) that may result
in a change in control of the Company.

Item 12.  Certain Relationships and Related Transactions

          Since January 1, 1996, the following transactions have occurred in
which persons who, at the time of such transactions, were directors, officers or
owners of more than 5% of the Company's common stock, had a direct or indirect
material interest.

          The Company and CECO have entered into a five (5) year written
management and consulting agreement pursuant to which the Company provides
management and financial consulting services to CECO. The Company advises CECO
on corporate policies, strategic and financial planning, mergers and
acquisitions, financing, long-term financial goals and growth plans and related
matters. This agreement was made as of January 1, 1994 and became effective as
of July 1, 1994. Pursuant to this agreement CECO paid the Company management and
financial consulting fees of $40,000 per month from July 1, 1994 through
December 31, 1994 ($240,000 total), and paid $20,000 per month ($240,000 total)
for the 1995, 1996 and 1997 fiscal years. The contract requires monthly fees of
$20,000 through the end of its term. The consulting agreement with CECO
terminates on December 31, 1998, and may be terminated earlier upon the
bankruptcy or liquidation of CECO or the Company, by the non-bankrupt party. The
consulting agreement may also be terminated upon the sale of substantially all
of the assets of CECO or the merger of CECO into another company, in which event
the Company is entitled to receive a severance fee of $240,000.

          On September 25, 1997, CECO borrowed $500,000 from the Company to help
fund the purchase of the assets for Busch. The loan is a subordinated, unsecured
loan. No principal may be repaid until the entire balance of a $1,000,000 loan
from CoreStates Bank, N.A. is repaid in full. The Company, however, receives
payments of interest. Interest accrues on the unpaid principal at the rate of
10% per annum.

          Andrew Halapin, President of Busch, is the beneficial owner of the
building in which Busch leases its principal office. The lease is a triple net
lease, with annual rent in the amount of $133,308.

                      AGREEMENT AND PLAN OF REORGANIZATION

         This Agreement and Plan of Reorganization (the "Agreement") is made as
of the 13th day of August, 1997 by and between CECO Environmental Corp., a New
York corporation (the "Acquiror"), CECO Filters, Inc., a Delaware corporation
("CECO"), and Steven I. Taub (the "Shareholder").

                                    RECITALS:

         A. The Shareholder is the owner of 1,165,000 shares of common stock
("CECO Shares") of CECO.

         B. Acquiror wishes to acquire and the Shareholder wishes to transfer
all of the CECO Shares in a transaction intended to qualify as a reorganization
within the meaning of Internal Revenue Code ("IRC") ss.368(a)(1)(B), as amended,
in exchange for 582,500 shares of the Acquiror's common stock (the "CEC
Shares").

         C. There is a dispute between Acquiror and the Shareholder regarding
the value of the CECO Shares. Because of said dispute, the Shareholder and the
Acquiror agree to place 100,000 of the CEC Shares (the "Escrowed Shares") into
an escrow subject to the amount by which gross revenues of CECO for the calendar
year 1998 equal or exceed target levels.

                                   AGREEMENT:

         NOW, THEREFORE, in consideration of the mutual representations,
warranties and undertakings contained herein, the parties hereto agree as
follows:

         1. Exchange of Shares. In accordance with the terms and subject to the
conditions contained herein, Acquiror hereby agrees to issue to the Shareholder
the CEC Shares in exchange for the CECO Shares.

         2. The Closing.

               2.1 Delivery by Acquiror. The Acquiror shall deliver to the
Shareholder certificates representing 482,500 of the CEC Shares (the "Delivered
Shares") issued in the name of the Shareholder and the Acquiror shall deliver
the certificates representing the Escrowed Shares issued in the name of the
Shareholder to the Acquiror or such other party as the Acquiror and Shareholder
agree upon, who shall hold such Escrowed Shares as escrowee ("Escrowee").

               2.2 Delivery by Shareholder. The Shareholder shall deliver to the
Acquiror the CECO Shares endorsed in blank or


<PAGE>

accompanied by assignments separate from certificate sufficient to transfer the
CECO Shares into the name of the Acquiror. The Shareholder shall deliver to the
Escrowee assignments separate from certificates sufficient to transfer both
fifty percent (50%) and one hundred percent (100%) of the Escrowed Shares to the
Acquiror.

               2.3 Closing Date. The closing of the transaction contemplated
hereby (the "Closing") shall occur at a time, date and place mutually agreed by
the parties hereto.

         3. Escrowed Shares.

               3.1 Release of Escrowed Shares. The Escrowed Shares and
assignments separate from certificates, shall be released to the Shareholder
and/or the Acquiror in accordance with subsections 3.1(a)-(c) below following
the receipt by the Acquiror of CECO's audited financial statements for the year
ending December 31, 1998, as prepared by CECO's regular independent accountants.

               (a) Gross Revenues Equal to or Greater Than 1997 Revenues. In the

the event that the gross revenues of CECO for the year ending December 31, 1998
are equal to or greater than ninety-five percent (95%) of the gross revenues of
CECO for the year ending December 31, 1997, but less than one hundred percent
(100%) of the gross revenues for the year ending December 31, 1997, as shown by

         The Plan shall be administered by a Committee which may be appointed by
the Board from time to time (collectively referred to as the "Administrator").
The Administrator shall have all of the powers vested in it under the provisions
of the Plan, including but not limited to exclusive authority (where applicable

to whom, and the time or times at which, options shall be granted, the number of
shares subject to each option and the option price and terms and conditions of
each option. The Administrator shall have full power and authority to administer
and interpret the Plan, to make and amend rules, regulations and guidelines for
administering the Plan, to prescribe the form and conditions of the respective
stock option agreements (which may vary from Optionee to Optionee) evidencing
each option and to make all other determinations necessary or advisable for the
administration of the Plan. The Administrator's interpretation of the Plan, and
all actions taken, and determinations made by the Administrator pursuant to the
power vested in it hereunder, shall be conclusive and binding on all parties
concerned.

         No member of the Committee shall be liable for any action taken or
determination made in good faith in connection with the administration of the

options under this Plan to some or all participants then holding options or may
grant options solely or partially to new participants. In designating
participants, the Administrator shall also determine the number of shares to be
optioned to each such participant. The Administrator may from time to time

under the Plan; provided, however, that the total number of shares of Option
Stock reserved for options under this Plan shall be subject to adjustment as
provided in Section 11 of the Plan. In the event that any outstanding option
under the Plan for any reason expires or is terminated prior to the exercise
thereof, the shares of Option Stock allocable to the unexercised portion of such
option shall continue to be reserved for options under the Plan and may be
optioned hereunder.

                                    SECTION 7

                                DURATION OF PLAN

         Incentive stock options may be granted pursuant to the Plan from time
to time during a period of ten (10) years from the effective date as defined in
Section 3. Any incentive stock option granted during such ten-year period shall
remain in full force and effect until the expiration of the option as specified
in the written stock option agreement and shall remain subject to the terms and
conditions of this Plan.

                                    SECTION 8

                                     PAYMENT

         Optionees may pay for shares upon exercise of options granted pursuant
to this Plan with cash, personal check, certified check, or such other form of
payment as may be authorized by the Administrator. The Administrator may, in its
sole discretion, limit the forms of payment available to the Optionee and may
exercise such discretion any time prior to the termination of the option granted
to the Optionee or upon any exercise of the option by the Optionee.

         With respect to payment in the form of Common Stock of the Company, the
Administrator may require advance approval or adopt such rules as it deems
necessary to assure compliance with Rule 16b-3, or any successor provision, as
then in effect, of the general rules and regulations under the Securities
Exchange Act of 1934, if applicable.

         Each incentive stock option granted pursuant to this Section 9 shall be
evidenced by a written stock option agreement (the "Option Agreement"). The
Option Agreement shall be in such form as may be approved from time to time by
the Administrator and may vary from Optionee to Optionee; provided, however,

share on the date the Administrator grants the option; provided, however, that
if an Optionee owns stock possessing more than ten percent (10%) of the total
combined voting power of all classes of stock of the Company or of its Parent or
any Subsidiary, the option price per share of an incentive stock option granted
to such Optionee shall not be less than one hundred ten percent (110%) of the
Fair Market Value of the Common Stock per share on the date of the grant of the
option. The Administrator shall have full authority and discretion in
establishing the option price and shall be fully protected in so doing.

         (b) Term and Exercisability of Incentive Stock Option. The term during
which any incentive stock option granted under the Plan may be exercised shall
be established in each case by the Administrator. To the extent required to
qualify the Option as an incentive stock option under Section 422 of the
Internal Revenue Code, or any successor provision, in no event shall any
incentive stock option be exercisable during a term of more than ten (10) years
after the date on which it is granted; provided, however, that if an Optionee
owns stock possessing more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company or of its parent or any Subsidiary,
the incentive stock option granted to such Optionee shall be exercisable during
a term of not more than five (5) years after the date on which it is granted.

         The Option Agreement shall state when the incentive stock option
becomes exercisable and shall also state the maximum term during which the
option may be exercised. In the event an incentive stock option is exercisable
immediately, the manner of exercise of the option in the event it is not
exercised in full immediately shall be specified in the Option Agreement. The
Administrator may accelerate the exercisability of any incentive stock option
granted hereunder which is not immediately exercisable as of the date of grant.

<PAGE>

         (c) Maximum Size of Incentive Stock Option As Such. To the extent that
the aggregate Fair Market Value of Common Stock for which an Incentive Stock
Option becomes exercisable by the Optionee for the first time in any calendar
year exceeds $100,000, the portion of such incentive stock option which exceeds
such $100,000 limitation shall be treated as a Non-Statutory Stock Option and
not an incentive stock option under Code Section 422. For purposes of this
Section 9, all incentive stock options granted to an Optionee by the Company, as
well as any options that may have been granted to the Optionee under any other
stock incentive plans of the Company or any Related Corporation which are
intended to comply with the provisions Code Section 422 shall be considered in
the order in which they were granted, and the Fair Market Value as of the time
they were granted.

         (d) Other Provisions. The Option Agreement authorized under this
Section 9 shall contain such other provisions as the Administrator shall deem
advisable. Any such Option Agreement shall contain such limitations and
restrictions upon the exercise of the option as shall be necessary to ensure
that such option will be considered an "incentive stock option" as defined in
Section 422 of the Internal Revenue Code or to conform to any change therein. To
the extent, if any, that the Option Agreement is classified as a formula award
plan under Rule 16b-3(c)(2)(ii) of the Securities and Exchange Act of 1933, the
formula provisions cannot be amended more often than once every six months
except to comport with changes in the Internal Revenue Code, ERISA, or the rules
thereunder.

                                   SECTION 10

                               TRANSFER OF OPTION

         No incentive stock option shall be transferable, in whole or in part,
by the Optionee other than by will or by the laws of descent and distribution
and, during the Optionee's lifetime, the option may be exercised only by the
Optionee. If the Optionee shall attempt any transfer of any incentive stock
option granted under the Plan during the Optionee's lifetime, such transfer
shall be void and the incentive stock option, to the extent not fully exercised,
shall terminate.

                                   SECTION 11

                            ANTI-DILUTION ADJUSTMENTS

         A pro rata adjustment for an increase or decrease in the number of
shares of Common Stock of the Company subject to the Plan or that may be awarded
to any individual in any year shall be made to give effect to any consolidation
of shares, the equivalent value in stock of cash dividends, stock dividends,
stock splits, stock combinations, recapitalization and other similar changes in
the capital structure of the Company. Pro rata adjustments shall be made in the
number, kind and price of shares of Common Stock of the Company covered by any
outstanding Option hereunder to give effect

<PAGE>

to any consolidation of shares, stock dividends, stock splits, stock
combinations, recapitalization and similar changes in the capital structure in
the Company, or a merger or dissolution or reorganization of the Company, after
the date the Option is granted so that the Optionee is treated in a manner
equivalent to that of holders of the underlying Common Stock.

<PAGE>

                                   SECTION 12

                            SECURITIES LAW COMPLIANCE

         No shares of Common Stock shall be issued pursuant to the Plan unless
and until there has been compliance, in the opinion of Company's counsel, with
all applicable legal requirements, including without limitation, those relating
to securities laws and stock exchange listing requirements. As a condition to
the issuance of Option Stock to Optionee, the Administrator may require Optionee
to (i) represent that the shares of Option Stock are being acquired for
investment and not resale and to make such other representations as the
Administrator shall deem necessary or appropriate to qualify the issuance of the
shares as exempt from the Securities Act of 1933 and any other applicable
securities laws, and (ii) represent that Optionee shall not dispose of the
shares of Option Stock in violation of the Securities Act of 1933 or any other
applicable securities laws.

         In the event of a transaction (as defined in Section 12 of the Plan)
which is treated as a "pooling of interests" under generally accepted accounting
principles, Optionee will comply with Rule 145 of the Securities Act of 1933 and
any other restrictions imposed under other applicable legal or accounting
principles if Optionee is an "affiliate" (as defined in such applicable legal
and accounting principles) at the time of the transaction, and Optionee will
execute any documents necessary to ensure compliance with such rules.

         The Company reserves the right to place a legend on any stock
certificate issued upon exercise of an option granted pursuant to the Plan to
assure compliance with this Section 13.

                                   SECTION 13

                             RIGHTS AS A SHAREHOLDER

         An Optionee (or the Optionee's successor or successors) shall have no
rights as a shareholder with respect to any shares covered by an option until
the date of the issuance of a stock certificate evidencing such shares. No
adjustment shall be made for dividends (ordinary or extraordinary, whether in
cash, securities or other property), distributions or other rights for which the
record date is prior to the date such stock certificate is actually issued
(except as otherwise provided in Section 12 of the Plan).

                                   SECTION 14

                              AMENDMENT OF THE PLAN

         The Board may from time to time, insofar as permitted by law, suspend
or discontinue the Plan or revise or amend it in any respect; provided, however,
that no such revision or amendment, except as is authorized in Section 12, shall
impair the terms and

<PAGE>

conditions of any option which is outstanding on the date of such revision or
amendment to the material detriment of the Optionee without the consent of the
Optionee. Notwithstanding the foregoing, no such revision or amendment shall (i)
materially increase the number of shares subject to the Plan except as provided
in Section 12 hereof, (ii) change the designation of the class of employees
eligible to receive options, (iii) decrease the price at which options may be
granted, or (iv) materially increase the benefits accruing to Optionees under
the Plan without the approval of the shareholders of the Company if such
approval is required for compliance with the requirements of any applicable law
or regulation. Furthermore, the Plan may not, without the approval of the
shareholders, be amended in any manner that will cause Incentive Stock Options
to fail to meet the requirements of Code Section 422 of the Internal Revenue
Code.

                                   SECTION 15

                        NO OBLIGATION TO EXERCISE OPTION

         The granting of an option shall impose no obligation upon the Optionee
to exercise such option. Further, the granting of an option hereunder shall not
impose upon the Company or any Subsidiary any obligation to retain the Optionee
in its employ for any period.

                                WARRANT AGREEMENT

                    ----------------------------------------







<PAGE>

         WARRANT AGREEMENT (the "Agreement") dated as of January 14, 1998
between CECO Environmental Corp., a New York corporation (the "Company"), and
Phillip DeZwirek (hereinafter referred to as a "Holder" or "DeZwirek").

                             W I T N E S S E T H :

         WHEREAS, DeZwirek is an employee, officer and director of the Company;
and

         WHEREAS, DeZwirek has, and continues to provide valuable services to
the Company;

and
         WHEREAS, the Company desires to grant to DeZwirek, and DeZwirek desires
to accept from the Company, warrant certificates giving DeZwirek the right to
purchase shares of the Company's Common Stock.
         NOW, THEREFORE, in consideration of the premises, the payment by
DeZwirek to the Company of an aggregate of ten dollars ($10.00), the agreements
herein set forth and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

         1. Grant. DeZwirek is granted the right to purchase, from the Company,
at any time from June 14, 1998 until 5:30 p.m., New York time, on January 14,
2008 (the "Expiration Date"), at which time the Warrants expire, up to an
aggregate of 250,000 shares (subject to adjustment as provided in Section 8
hereof) of common stock, par value $.01 per share, of the Company ("Common
Stock") at an initial exercise price (subject to adjustment as provided in
Section 11 hereof) of $2.75 per share (the "Exercise Price").

         2. Warrant Certificates. The warrant certificates (the "Warrant
Certificates") delivered and to be delivered pursuant to this Agreement shall be
in the form set forth in Exhibit

<PAGE>

A, attached hereto and made a part hereof, with such appropriate insertions,
omissions, substitutions, and other variations as required or permitted by this
Agreement.

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

         4. Exercise of Warrant.

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

<PAGE>

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

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

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

<PAGE>

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

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

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

         9. Registration Rights.

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

<PAGE>

         THE WARRANTS REPRESENTED BY THIS CERTIFICATE AND THE OTHER SECURITIES
         ISSUABLE UPON EXERCISE THEREOF MAY NOT BE OFFERED OR SOLD EXCEPT
         PURSUANT TO (i) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
         SECURITIES ACT OF 1933, (ii) TO THE EXTENT APPLICABLE, RULE 144 UNDER
         SUCH ACT (OR ANY SIMILAR RULE UNDER SUCH ACT RELATING TO THE
         DISPOSITION OF SECURITIES), OR (iii) AN OPINION OF COUNSEL, IF SUCH
         OPINION SHALL BE REASONABLY SATISFACTORY TO COUNSEL FOR THE ISSUER,
         THAT AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS AVAILABLE.

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


               9.2 Piggyback Registration. If, at any time commencing on the
date of this Agreement, and expiring on the Expiration Date, the Company
proposes to register any of its securities, not registered on the date hereof,
under the Act (other than in connection with a merger or pursuant to Form S-4 or
Form S-8) it will give written notice by registered mail, at least thirty (30)
days prior to the filing of each such registration statement, to the Holders of
the Warrants and/or the Warrant Shares of its intention to do so. If any of the
Holders of the Warrants and/or Warrant Shares notify the Company within twenty
(20) days after mailing of any such notice of its or their desire to include any
such securities in such proposed registration statement, the Company shall
afford such Holders of the Warrants and/or Warrant Shares the opportunity to
have any such Warrant Shares registered under such registration statement. In
the event that the managing underwriter for said offering advises the Company in
writing that in the underwriter's opinion the number of securities requested to
be included in such registration exceeds the number which can be sold in such
offering without causing a diminution

<PAGE>

in the offering price or otherwise adversely affecting the offering, the Company
will include in such registration (a) first, the securities the Company proposes
to sell, (b) second, the securities held by the entities that made the demand
for registration, (c) third, the Warrants and/or Warrant Shares requested to be
included in such registration which in the opinion of such underwriter can be
sold, pro rata among the Holders of Warrants and/or Warrant Shares on the basis
of the number of Warrants and/or Warrant Shares requested to be registered by
such Holders, and (d) fourth, other securities requested to be included in such
registration.

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

               9.3 Demand Registration.

                   (a) At any time commencing January 1, 1998 and expiring on
the Expiration Date, the Holders of the Warrants and/or Warrant Shares
representing a "Majority" (as hereinafter defined) of the Warrants and/or
Warrant Shares shall have the right on one occasion (which right is in addition
to the registration rights under Section 9.2 hereof), exercisable by written
notice to the Company, to have the Company prepare and file with the Securities
and Exchange Commission (the "Commission"), a registration statement and such
other documents, including a prospectus, as may be necessary in the opinion of
both counsel for the Company and counsel for the Holders, in order to comply
with the provisions of the Act, so as to permit a public offering and sale by
such Holders and any other Holders of the Warrants

<PAGE>

and/or Warrant Shares who notify the Company within fifteen (15) days after the
Company mails notice of such request pursuant to Section 9.3(b) hereof
(collectively, the "Requesting Holders") of their respective Warrant Shares so
as to allow the unrestricted sale of the Warrant Shares to the public from time
to time until the earlier of the following: (i) the Expiration Date, or (ii) the
date on which all of the Warrant Shares requested to be registered by the
Requesting Holders have been sold (the "Registration Period").

                   (b) The Company covenants and agrees to give written notice
of any registration request under this Section 9.3 by any Holder or Holders
representing a Majority of the Warrants and/or Warrant Shares to all other
registered Holders of the Warrants and the Warrant Shares within ten (10) days
from the date of the receipt of any such registration request.
                   
                   (c) In addition to the registration rights under Section 9.2
and subsection (a) of this Section 9.3, at any time commencing January 1, 1998
and expiring on the Expiration Date, the Holders of Warrants and/or Warrant
Shares shall have the right on one occasion, exercisable by written request to
the Company, to have the Company prepare and file with the Commission a
registration statement so as to permit a public offering and sale by such
Holders of their respective Warrant Shares from time to time until the first to
occur of the following: (i) the expiration of this Agreement, or (ii) all of the
Warrant Shares requested to be registered by such Holders have been sold;
provided, however, that the provisions of Section 9.4(b) hereof shall not apply
to any such registration request and registration and all costs incident thereto
shall be at the expense of the Holder or Holders making such request.

               9.4 Covenants of the Company With Respect to Registration. In
connection with any registration under Section 9.2 or 9.3 hereof, the Company
covenants and agrees as follows:

<PAGE>

                   (a) The Company shall use its best efforts to file a
registration statement within ninety (90) days of receipt of any demand
therefor, and to have any registration statements declared effective at the
earliest possible time, and shall furnish each Holder desiring to sell Warrant
Shares such number of prospectuses as shall reasonably be requested. The Company
shall also file such applications and other documents as may be necessary to
permit the sale of the Warrant Shares to the public during the Registration
Period in those states to which the Company and the holders of the Warrants
and/or Warrant Shares shall mutually agree.

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

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

                   (d) The Company shall indemnify the Holder(s) of the Warrant
Shares to be sold pursuant to any registration statement and each person, if
any, who controls such

<PAGE>

Holder(s) within the meaning of Section 15 of the Act or Section 20(a) of the
Securities Exchange Act of 1934, as amended ("Exchange Act"), against all loss,
claim, damage, expense or liability (including all expenses reasonably incurred
in investigating, preparing or defending against any claim whatsoever) to which
any of them may become subject under the Act, the Exchange Act or otherwise,
arising from such registration statement.

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

<PAGE>

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

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

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

<PAGE>

                   (h) The Company shall not permit the inclusion of any
securities other than the Warrant Shares to be included in any registration
statement filed pursuant to Section 9.3 hereof, or permit any other registration
statement (other than a registration statement on Form S-4 or S-8) to be or
remain effective during a one hundred and eighty (180) day period following the
effective date of a registration statement filed pursuant to Section 9.3 hereof,
without the prior written consent of the Holder(s) of the Warrants and Warrant
Shares representing a Majority of such securities or as otherwise required by
the terms of any existing registration rights granted prior to the date of this
Agreement by the Company to the holders of any of the Company's securities.

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

<PAGE>

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

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

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

<PAGE>

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

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

                   (b) Notify the Company, at any time when a prospectus
relating to the Warrant Shares covered by a registration statement is required
to be delivered under the Act, of the happening of any event with respect to
such selling Holder as a result of which the prospectus included in such
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances then existing.

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

               11.1 Dividend, Subdivision and Combination. In case the Company
shall (i) declare a dividend or make a distribution on its outstanding shares of
Common Stock in shares of Common Stock, (ii) subdivide or reclassify its
outstanding shares of Common Stock into a

<PAGE>

greater number of shares, or (iii) combine or reclassify its outstanding shares
of Common Stock into a smaller number of shares, the Exercise Price in effect at
the time of the record date for such dividend or distribution or of the
effective date of such subdivision, combination or reclassification shall be
adjusted so that it shall equal the price determined by multiplying the Exercise
Price by a fraction, the denominator of which shall be the number of shares of
Common Stock outstanding after giving effect to such action, and the numerator
of which shall be the number of shares of Common Stock outstanding immediately
prior to such action. Such adjustment shall be made successively whenever any
event listed above shall occur.

               11.2 Adjustment in Number of Securities. Upon each adjustment of
the Exercise Price pursuant to the provisions of this Section 11, the number of
Warrant Shares issuable upon the exercise at the adjusted Exercise Price of each
Warrant shall be adjusted to the nearest number of whole shares of Common Stock
determined by multiplying a number equal to the Exercise Price in effect
immediately prior to such adjustment by the number of the applicable Warrant
Shares issuable upon exercise of the Warrants immediately prior to such
adjustment and dividing the product so obtained by the adjusted Exercise Price.

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

               11.4 Merger or Consolidation. In case of any consolidation of the
Company with, or merger of the Company into, another corporation (other than a
consolidation or merger

<PAGE>

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

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

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

                   (b) Upon the issuance or sale of Common Stock (or any other
security convertible, exercisable, or exchangeable into shares of Common Stock)
upon the direct or indirect conversion, exercise, or exchange of any options,
rights, warrants, or other securities or indebtedness of the Company outstanding
as of the date of this Agreement or granted pursuant to any stock option plan of
the Company in existence as of the date of this Agreement, pursuant to the terms
thereof or issued pursuant to any stock purchase plan in existence as of the
date of this Agreement, pursuant to the terms thereof; or

                   (c) If the amount of said adjustment shall be less than ten
cents ($.10)

<PAGE>

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

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

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

         13. Elimination of Fractional Interests. The Company shall not be
required to issue certificates representing fractions of shares of Common Stock
or other securities upon the exercise of the Warrants, nor shall it be required
to issue scrip or pay cash in lieu of fractional interests, it being the intent
of the parties that all fractional interests shall be eliminated by rounding any
fraction up to the nearest whole number of shares of Common Stock or other
securities, properties or rights.

<PAGE>

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

         15. Notices to Warrant Holders. Nothing contained in this Agreement
shall be construed as conferring upon the Holder(s) of the Warrants the right to
vote or to consent or to

<PAGE>

receive notice as a stockholder in respect of any meetings of stockholders for
the election of directors or any other matter, or as having any rights
whatsoever as a stockholder of the Company. If, however, at any time prior to
the expiration of the Warrants and their exercise, any of the following events
shall occur:

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

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

               (c) a dissolution, liquidation or winding up of the Company
(other than in connection with a consolidation or merger) or a sale of all or
substantially all of its property, assets and business as an entirety shall be
proposed; then in any one or more of said events, the Company shall give written
notice to the registered holders of the Warrants of such event at least fifteen
(15) days prior to the date fixed as a record date or the date of closing the
transfer books for the determination of the stockholders entitled to such
dividend, distribution, convertible or exchangeable securities or subscription
rights, or entitled to vote on such proposed dissolution, liquidation, winding
up or sale. Such notice shall specify such record date or the date of closing
the transfer books, as the case may be. Failure to give such notice or any
defect therein shall

<PAGE>

not affect the validity of any action taken in connection with the declaration
or payment of any such dividend, or the issuance of any convertible or
exchangeable securities, or subscription rights, options or warrants, or any
proposed dissolution, liquidation, winding up or sale.

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

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

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

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

<PAGE>

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

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

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

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

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

         23. Benefits of this Agreement. Nothing in this Agreement shall be
construed to give to any person or corporation other than the Company and
DeZwirek and any other registered

<PAGE>

Holder(s) of the Warrant Certificates or Warrant Shares any legal or equitable
right, remedy or claim under this Agreement; and this Agreement shall be for the
sole and exclusive benefit of the Company and DeZwirek and any other Holder(s)
of the Warrant Certificates or Warrant Shares.

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

<PAGE>

         25. IN WITNESS WHEREOF, the parties hereto have caused this Agreement
to be duly executed, as of the day and year first above written.

THE WARRANTS REPRESENTED BY THIS CERTIFICATE AND THE OTHER SECURITIES ISSUABLE
UPON EXERCISE THEREOF MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO (i) AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, (ii) TO THE
EXTENT APPLICABLE, RULE 144 UNDER SUCH ACT (OR ANY SIMILAR RULE UNDER SUCH ACT
RELATING TO THE DISPOSITION OF SECURITIES), OR (iii) AN OPINION OF COUNSEL, IF
SUCH OPINION SHALL BE REASONABLY SATISFACTORY TO COUNSEL FOR THE ISSUER, THAT AN
EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS AVAILABLE.

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

                            EXERCISABLE ON OR BEFORE
                   5:30 P.M., NEW YORK TIME, JANUARY 14, 2008

                                   Warrant No. ____




                               WARRANT CERTIFICATE

         This Warrant Certificate certifies that ______________________, or
registered assigns, is the registered holder of Warrants to purchase initially,
at any time from June 14, 1998 until 5:30 p.m., New York time, on January 14,
2008 ("Expiration Date"), up to ____________ shares, of fully-paid and
non-assessable common stock, $.01 par value ("Common Stock") of CECO
Environmental Corp., a New York corporation (the "Company"), at the initial
exercise price, subject to adjustment in certain events, of ($2.75) per share
upon surrender of this Warrant Certificate and payment of the Exercise Price at
the principal executive office of the Company, but subject to the conditions set
forth herein. Payment of the Exercise Price shall be made by certified or
official bank check in United States dollars payable to the order of the
Company.

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

         The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants issued pursuant to the Warrant Agreement, which
Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to for a

                                     EXH A-1

<PAGE>

description of the rights, limitation of rights, obligations, duties and
immunities thereunder of the Company and the holders (the words "holders" or
"holder" meaning the registered holders or registered holder) of the Warrants.

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

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

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

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

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

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

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

("Bank"), the principal sum of One Million Dollars ($1,000,000.00), together
with interest thereon upon the following terms:

         26. Term Note. This Note is the "Term Note" as defined in that certain
Loan Agreement of even date herewith among Borrower and Bank (such Loan
Agreement, as the same may be amended, supplemented or restated from time to
time, being the "Loan Agreement") and, as such, shall be construed in accordance

<PAGE>


                                 LOAN AGREEMENT

         THIS LOAN AGREEMENT (the "Agreement") is made effective the 25th day of
September, 1997, by and between CECO FILTERS, INC. ("Borrower") and CORESTATES
BANK, N.A. ("Bank").

                                   BACKGROUND

         A. Borrower has requested that Bank extend certain credit facilities to
Borrower, which Bank is willing to do on the terms set forth herein.

         B. Capitalized terms not otherwise defined herein will have the
meanings set forth therefor in Section 12 of this Agreement.

         NOW, THEREFORE, in consideration of the terms and conditions contained
herein, and of any extensions of credit now or hereafter made to or for the
benefit of Borrower by Bank, the parties hereto, intending to be legally bound
hereby, agree as follows:

1.       THE LINE; TERM LOAN; USE OF PROCEEDS.

         1.1. Line of Credit. Bank will establish for Borrower subject to the
terms and conditions hereof, a revolving demand line of credit (the "Line")
pursuant to which Bank will from time to time make loans or other extensions of
credit to Borrower in an aggregate amount not exceeding at any time the lesser
of: (a) the sum of (i) an amount up to eighty percent (80%) of the Eligible
Receivables, plus (ii) the Permitted Out-of-Formula Advance; or (b) One Million
Five Hundred Thousand Dollars ($1,500,000.00). Within the limitations set forth
above, Borrower may borrow, repay and reborrow under the Line. The Line shall be
subject to all terms and conditions set forth in all of the Loan Documents (as
hereafter defined) which terms and conditions are incorporated herein.
Borrower's obligation to repay the loans and extensions of credit under the Line
shall be evidenced by Borrower's demand promissory note (the "Line Note") in the
face amount of One Million Five Hundred Thousand Dollars ($1,500,000.00), which
shall be in the form attached hereto as Exhibit "A", with the blanks
appropriately filled in. The Line Note shall amend and replace, but not repay or
satisfy, Borrower's obligations to Bank under a certain Master Demand Note dated
July 23, 1997.

         1.2. Term Loan. Bank will lend to Borrower and Borrower will borrow
from Bank One Million Dollars ($1,000,000.00) (the "Term Loan"). Borrower's
obligation to repay the Term Loan Shall be evidenced by Borrower's promissory
note in the original principal amount of One Million dollars ($1,000,000.00)
(the "Term Note"), substantially in the form attached hereto as Exhibit "B" with
the blanks appropriately filled in.

         1.3. Use of Proceeds. Borrower agrees to use (a) advances under the
Line for proper working capital purposes and to finance the acquisition of
certain assets of Busch Environmental Corporation; and (b) the proceeds of the
Term Loan to finance the acquisition of certain assets of Busch Environmental
Corporation.

<PAGE>

         1.4. Method of Advances. On any Business Day, Borrower may request an
advance under the Line by making such request to the bank officer designated by
Bank no later than noon Philadelphia time on the Business Day such advance is
requested to be funded, and delivery to Bank of any documentation as Bank may
from time to time require. Subject to the terms and conditions of this
Agreement, Bank may make the proceeds of an advance available to Borrower by
crediting such proceeds to Borrower's deposit account with Bank. Such request
may be by telephone, unless Bank has advised Borrower that written requests are
required. Bank may require prompt written confirmation of any telephone request
and additional back-up documentation, from time to time. Each request for an
advance under the Line shall be conclusively presumed to be made by a person
authorized by Borrower to do so.

         1.5. Letters of Credit. Bank, at its sole discretion, may issue for the
account of Borrower merchandise and standby letters of credit in form and
content satisfactory to Bank, at its sole discretion, with a term not to exceed
the earlier to occur of (a) ninety (90) days (for merchandise letters of
credit), or (b) twelve (12) months (for standby letters of credit).
Notwithstanding the foregoing, (i) at no time shall the aggregate face amount of
all outstanding letters of credit issued under the Line exceed the amount of
Five Hundred Thousand Dollars ($500,000.00); and (ii) at no time shall the
principal balance of the Line, plus the aggregate face amount of all outstanding
letters of credit issued under the Line exceed the amount of the loans and
extensions of credit then available to Borrower under the Line pursuant to
advances as described under Section 1.1.

         Borrower will execute a letter of credit application and letter of
credit agreement, and such other documents as may be required by Bank in
connection with the issuance of letters of credit hereunder. The outstanding
face amount of all letters of credit issued by Bank pursuant hereto will reduce
Borrower's ability to borrow under the Line as if such face amount were an
advance under the Line. In the event that Bank pays any sums due pursuant to
such letters of credit for any reason, such payment shall be deemed to be an
advance under the Line repayable by Borrower pursuant to the terms hereof.

         In the event that the Line is terminated for any reason or demand is
made thereunder, Borrower will deposit with Bank an amount equal to the face
amount of all letters of credit then outstanding which have been issued
hereunder, plus all fees related thereto or to accrue thereunder. Such funds
will be held by Bank as cash collateral to secure Borrower's obligations
hereunder.

         1.6. Collection of Receivables; Proceeds of Collateral.

              (a) Lockbox. Borrower and New Busch Co., Inc. will collect their
accounts receivable only in the ordinary course of business. Borrower and New
Busch Co., Inc. will notify all of their account debtors to forward all accounts
receivable collections owed to Borrower and New Busch Co., Inc. to a lockbox
maintained by Bank, and will execute such lockbox agreements as may be required
by Bank and will pay to Bank all customary fees in connection with such lockbox
arrangement. Immediately upon receipt, Borrower will forward to Bank all other
checks, drafts and other monies received by Borrower or New Busch Co., Inc.
which are proceeds of the Collateral to the lockbox maintained by Bank.

<PAGE>

              (b) Operating Account. All accounts receivable collections of
Borrower and New Busch Co., Inc. and all checks, drafts and other monies
received by Borrower and New Busch Co., Inc. which are proceeds of the
Collateral will be deposited in Borrower's and New Busch Co., Inc.'s operating
account maintained at Bank (collectively, the "Operating Account").

              (c) Collected Funds. The Operating Account will be cleared by Bank
daily on mutually agreed upon days as to collected funds, and such collected
funds will be applied to the principal balance of and accrued interest on the
Line, at the Bank's election. Upon the occurrence of an Event of Default, Bank
may apply such collected funds to the Bank Indebtedness in such order as it may
elect.

              (d) Proceeds of Collateral. Borrower and New Busch Co., Inc. agree
that all monies, checks, notes, instruments, drafts or other payments relating
to or constituting proceeds of any accounts receivable or other Collateral of
Borrower and New Busch Co., Inc. which come into the possession or under the
control of Borrower and/or New Busch Co., Inc. or any employees, agents or other
persons acting for or in concert with Borrower and/or New Busch Co., Inc., shall
be received and held in trust for Bank and such items shall be the sole and
exclusive property of Bank. Immediately upon receipt thereof, Borrower, New
Busch Co., Inc. and such other persons shall remit the same or cause the same to
be remitted, in kind, to Bank. Borrower and New Busch Co., Inc. shall deliver or
cause to be delivered to Bank, with appropriate endorsement and assignment to
Bank with full recourse to Borrower and New Busch Co., Inc., all instruments,
notes and chattel paper constituting an account receivable or proceeds thereof
or other Collateral. Bank is hereby authorized to open all mail addressed to
Borrower and New Busch Co., Inc. and endorse all checks, drafts or other items
for payment on behalf of Borrower and New Busch Co., Inc. Bank is granted a
power of attorney by Borrower and New Busch Co., Inc. with full power of
substitution to execute on behalf of Borrower and New Busch Co., Inc. and in
their names or to endorse their names on any check, draft, instrument, note or
other item of payment or to take any other action or sign any document in order
to effectuate the foregoing. Such power of attorney being coupled with an
interest is irrevocable.

2.       INTEREST RATE.

         2.1. Interest on the Line. Interest on the unpaid principal balance of
the Line will accrue from the date of advance until final payment thereof at a
per annum rate which is one-half of one percent (1/2 of 1%) in excess of the
Prime Rate in effect from time to time (such interest rate to change immediately
upon any change in the Prime Rate).

         2.2. Interest on Term Loan. Interest on the unpaid principal balance of
the Term Loan will accrue until final payment thereof at the rate per annum
which is one-half of one percent (1/2 of 1%) in excess of the Prime Rate in
effect from time to time (such interest rate to change immediately upon any
change in the Prime Rate).

         2.3. Default Interest. Interest will accrue on the principal balance of
the Line and the Term Loan after demand or the occurrence of an Event of Default
at a rate which is three percent (3%) in excess of the Prime Rate in effect from
time to time (the "Default Rate").

         2.4. Post Judgment Interest. Any judgment obtained for sums due
hereunder or

<PAGE>

under the Loan Documents will accrue interest at the applicable default rate set
forth above until paid.

         2.5. Calculation. Interest will be computed on the basis of a year of
360 days and paid for the actual number of days elapsed.

         2.6. Limitation of Interest to Maximum Lawful Rate. In no event will
the rate of interest payable hereunder exceed the maximum rate of interest
permitted to be charged by applicable law (including the choice of law rules)
and any interest paid in excess of the permitted rate will be refunded to
Borrower. Such refund will be made by application of the excessive amount of
interest paid against any sums outstanding hereunder and will be applied in such
order as Bank may determine. If the excessive amount of interest paid exceeds
the sums outstanding, the portion exceeding the sums outstanding will be
refunded in cash by Bank. Any such crediting or refunding will not cure or waive
any default by Borrower. Borrower agrees, however, that in determining whether
or not any interest payable hereunder exceeds the highest rate permitted by law,
any non-principal payment, including without limitation prepayment fees and late
charges, will be deemed to the extent permitted by law to be an expense, fee,
premium or penalty rather than interest.

3.       PAYMENTS AND FEES.

         3.1. Interest Payments on the Line. Borrower will pay interest on the
principal balance of the Line on the first day of each calendar month commencing
on the first day of the first calendar month following the date of this
Agreement.

         3.2. Principal Payments on the Line. Borrower will pay the outstanding
principal balance of the Line, together with any accrued and unpaid interest
thereon, and any other sums due pursuant to the terms hereof, ON DEMAND. If any
Out-Of-Formula Advance arises or exists under the Line (other than a Permitted
Out-of-Formula Advance) for any reason whatsoever, Borrower will repay such
Out-Of-Formula Advance immediately, without demand. THE INCLUSION OF EVENTS OF
DEFAULT AND COVENANTS IN THE LOAN DOCUMENTS SHALL NOT IN ANY WAY LIMIT THE
DEMAND NATURE OF THE LINE. BORROWER UNDERSTANDS THAT THE BANK MAY MAKE DEMAND
FOR PAYMENT AT ANY TIME FOR ANY OR NO REASON, WITHOUT REGARD TO WHETHER AN EVENT
OF DEFAULT HAS OCCURRED.

         3.3. Principal and Interest Payments on the Term Loan. Borrower will
pay the principal of the Term Loan and accrued interest thereon in forty-seven
(47) equal and consecutive monthly installments of Twenty Thousand Eight Hundred
Thirty-Three Dollars and Thirty-Three Cents ($20,833.33) each, plus interest, on
the first day of each calendar month commencing on October 1, 1997 and in one
final payment of the remaining principal balance plus all accrued and unpaid
interest thereon on September 1, 2001. Notwithstanding the foregoing payment
schedule, the proceeds of any stock or equity offering initiated by Borrower
during the term of the Term Loan shall be applied against the principal balance
of the Term Loan and any then outstanding Permitted Out-of-Formula Advances,
together with any accrued interest due thereon, in inverse order of maturity.

         3.4. Letter of Credit Fees. Borrower shall pay all fees and charges in
connection with the issuance, renewal, negotiation and cancellation of each
merchandise and standby letter of credit as may be customarily charged by Bank.
Such fees shall be computed on the basis of a year of 360 days.

<PAGE>

         3.5. Late Charge. In the event that Borrower fails to pay any
principal, interest or other fees or expenses payable hereunder for a period of
at least fifteen (15) days, in addition to paying such sums, Borrower will pay
to Bank a late charge equal to five percent (5%), of such past due payment as
compensation for the expenses incident to such past due payment.

         3.6. Prepayment of Term Loan. Borrower may prepay all or any part of
the principal balance of the Term Loan at any time, without penalty or premium.
All prepayments will be applied to the regularly scheduled payments in the
inverse order in which they are due.

         3.7. Payment Method. Borrower irrevocably authorizes Bank to debit all
payments required to be made by Borrower hereunder, under the Line and the Term
Loan, on the date due, from any deposit account maintained by Borrower with
Bank. Otherwise, Borrower will be obligated to make such payments directly to
Bank. All payments are to be made in immediately available funds. If Bank
accepts payment in any other form, such payment shall not be deemed to have been
made until the funds comprising such payment have actually been received by or
made available to Bank.

         3.8. Application of Payments. Any and all payments on account of the
Line and the Term Loan will be applied to accrued and unpaid interest,
outstanding principal and other sums due hereunder or under the Loan Documents,
in such order as Bank, in its discretion, elects. If Borrower makes a payment or
payments and such payment or payments, or any part thereof, are subsequently
invalidated, declared to be fraudulent or preferential, set aside or are
required to be repaid to a trustee, receiver, or any other person under any
bankruptcy act, state or federal law, common law or equitable cause, then to the
extent of such payment or payments, the obligations or part thereof hereunder
intended to be satisfied shall be revived and continued in full force and effect
as if said payment or payments had not been made.

         3.9. Loan Account. Bank will open and maintain on its books a loan
account (the "Loan Account") with respect to advances made, repayments,
prepayments, the computation and payment of interest and fees and the
computation and final payment of all other amounts due and sums paid to Bank
under this Agreement. Except in the case of manifest error in computation, the
Loan Account will be conclusive and binding on the Borrower as to the amount at
any time due to Bank from Borrower under this Agreement or the Notes.

4.       SECURITY.

provisional or final) at any time held and other indebtedness at any time owing

of the Bank Indebtedness, and to pay or transfer such amount or property to Bank
for application to the Bank Indebtedness.

         7.5. Delay or Omission Not Waiver. Neither the failure nor any delay on
the part of Bank to exercise any right, remedy, power or privilege under the
Loan Documents upon the occurrence of any Event of Default or otherwise shall
operate as a waiver thereof or impair any such right, remedy, power or
privilege. No waiver of any Event of Default shall affect any later Event of
Default or shall impair any rights of Bank. No single, partial or full exercise
of any rights, remedies, powers and privileges by the Bank shall preclude
further or other exercise thereof. No course of dealing between Bank and
Borrower shall operate as or be deemed to constitute a waiver of Bank's rights
under the Loan Documents or affect the duties or obligations of Borrower.

<PAGE>

         7.6. Remedies Cumulative; Consents. The rights, remedies, powers and
privileges provided for herein shall not be deemed exclusive, but shall be

review, negotiation, execution, delivery and administration of the Loan

without limitation, attorney's fees and expenses, and the cost of appraisals and
reappraisals of Collateral), and the cost of periodic lien searches and tax
clearance certificates, as Bank deems advisable;

               (b) all losses, costs and expenses in connection with the
enforcement, protection and preservation of the Bank's rights or remedies under
the Loan Documents, or any other agreement relating to any Bank Indebtedness, or
in connection with legal advice relating to the rights or responsibilities of
Bank (including without limitation court costs, attorney's fees and expenses of
accountants and appraisers); and

               (c) any and all stamp and other taxes payable or determined to be
payable in connection with the execution and delivery of the Loan Documents, and
all liabilities to which Bank may become subject as the result of delay in
paying or omission to pay such taxes.

         In the event Borrower shall fail to pay taxes, insurance, assessments,
costs or expenses which it is required to pay hereunder, or fails to keep the
Collateral free from security interests or lien (except as expressly permitted
herein), or fails to maintain or repair the Collateral as required hereby, or
otherwise breaches any obligations under the Loan Documents, Bank in its
discretion, may make expenditures for such purposes and the amount so expended
(including attorney's fees and expenses, filing fees and other charges) shall be
payable by Borrower on demand and shall constitute part of the Bank
Indebtedness.

         With respect to any amount required to be paid by Borrower under this
Section, in the event Borrower fails to pay such amount on demand, Borrower
shall also pay to Bank interest thereon at the default rate set forth for the
Line.

         Borrower agrees to indemnify and hold harmless, Bank and Bank's
officers, directors, shareholders, employees and agents, from and against any
and all claims, liabilities, losses, damages, costs and expenses (whether or not
such Person is a party to any litigation), including attorney's fees and costs
and costs of investigation, document production, attendance at depositions or
other discovery with respect to or arising out of this Agreement, the use of any
proceeds advanced hereunder, the transactions contemplated hereunder, or any
claim, demand, action or cause of action being asserted against Borrower or any
of its Affiliates.

         Borrower's obligations under this Section shall survive termination of
this Agreement and repayment of the Bank Indebtedness.

         7.8. Time is of the Essence. Time is of the essence in Borrower's
performance of its obligations under the Loan Documents.

<PAGE>

         7.9. Acknowledgment of Confession of Judgment Provisions. BORROWER
ACKNOWLEDGES AND AGREES THAT THE NOTES AND THE LOAN DOCUMENTS CONTAIN PROVISIONS
WHEREBY BANK MAY ENTER JUDGMENT BY CONFESSION AGAINST BORROWER AFTER DEMAND OR
THE OCCURRENCE OF AN EVENT OF DEFAULT, AS THE CASE MAY BE. BEING FULLY AWARE OF
ITS RIGHTS TO PRIOR NOTICE AND HEARING ON THE QUESTION OF THE VALIDITY OF ANY
CLAIMS THAT MAY BE ASSERTED AGAINST IT BY BANK UNDER THE NOTES AND LOAN
DOCUMENTS, BEFORE JUDGMENT CAN BE ENTERED, BORROWER HEREBY WAIVES THESE RIGHTS
AND AGREES AND CONSENTS TO BANK ENTERING JUDGMENT AGAINST BORROWER BY
CONFESSION. ANY PROVISION IN A CONFESSION OF JUDGMENT IN ANY OF THE LOAN
DOCUMENTS FOR AN ATTORNEY'S COLLECTION COMMISSION SHALL IN NO WAY LIMIT
BORROWER'S LIABILITY TO REIMBURSE BANK FOR ALL LEGAL FEES ACTUALLY INCURRED BY
BANK, EVEN IF SUCH FEES ARE IN EXCESS OF THE ATTORNEY'S COLLECTION COMMISSION
PROVIDED FOR IN SUCH CONFESSION OF JUDGMENT.

body hereafter constitute exercising similar functions, or that the Lessor may
deem reasonably necessary to prevent waste or deterioration on the Demised
Premises. Nothing herein shall imply any duty upon the part of the Lessor to do
any such work that under any provisions of this Lease the Lessee is required to
perform, and the performance thereof by the Lessor shall not constitute a waiver
of the Lessee's default in failing to perform the same. The Lessor may, during
the progress of any work in the Demised Premises, keep and store upon the

<PAGE>

Demised Premises, in areas mutually convenient to Lessor and Lessee, all
necessary materials, tools and equipment required for said work. Lessee shall
fully reimburse Lessor for the cost of any work performed by Lessor pursuant to
this Article 6 which amount shall be deemed to be additional rent; provided,
however, that Lessor shall be responsible for and pay the cost of any work
performed in order to fulfill Lessor's obligations under this Lease.

ARTICLE 7. INSPECTION BY PROSPECTIVE PURCHASERS AND TENANTS.
           The Lessor shall have the right, upon the giving of forty-eight (48)
hours prior notice to Lessee, to enter the Demised Premises during the Lessee's
usual business hours (a) to exhibit the same to prospective purchasers at any
time during the Lease term and (b) to exhibit the same to prospective tenants
within six (6) months prior to the Expiration Date. A representative of Lessor
shall always accompany any prospective purchaser or tenant on any of the
aforesaid inspections. Lessor shall also have the right, at any time during the
Lease term or any renewal thereof, to display the usual "For Sale" signs on the
Demised Premises and also the right, within six (6) months prior to the
Expiration Date, to display the usual "For Rent" signs; provided, however, that
any such "For Sale" or "For Rent" sign shall be displayed in such a manner so as
not to unreasonably interfere with the Lessee's business, and Lessee agrees that
Lessee shall not disturb any such signs placed upon the Demised Premises.

ARTICLE 8. SIGNS.
           Lessee shall not install, maintain or display upon

<PAGE>

the Demised Premises any exterior signs without the prior written approval of
Lessor, which approval shall not be unreasonably withheld. Lessor agrees to make
a determination of whether to grant or withhold such approval and to inform
Lessee of same in writing within thirty (30) days of any such request by Lessee.
Lessor hereby grants its approval of all signs, logos and insignia which are
shown on the Plans and Specifications.

ARTICLE 9. INDEMNIFICATION.
           During the Term of this Lease, Lessee agrees to indemnify and save
Lessor harmless against and form any and all claims by or on behalf of any
person(s), firm(s), corporation(s) or any other entity arising from anything
whatsoever done in or about the Demised Premises; and Lessee will further
indemnify and save Lessor harmless against and from any and all claims arising
from the conditions of the Demised Premises, or arising from any breach or
default on the part of the Lessee in the performance of any covenant or
agreement on the part of the Lessee to be performed pursuant to the terms and
conditions of this Lease, or arising from any willful or negligent act or
omission of the Lessee or any of its agents, servants or employees, or arising
from any accident, injury or damage whatsoever caused to any person(s), firm(s),
corporation(s) or any other entity occurring in or about the Demised Premises;
and Lessee will further indemnify and save Lessor harmless against and from all
costs, counsel fees, expenses and liabilities reasonably

<PAGE>

incurred in connection with any such claim or action or proceeding brought
thereon; and, in case any action or proceeding be brought against the Lessor by
reason of any such claim, the Lessee covenants to resist or defend such action
or proceeding by counsel, reasonably satisfactory to the Lessor; provided,
however, that Lessee's obligation to indemnify Lessor hereunder shall not extend
to any matters or occurrences (or their consequences) arising from or associated
with any negligent or willful act or omission of Lessor or his agents, servants
or employees.

ARTICLE 10. RELEASE OF LIABILITY.
           Lessee agrees to release and indemnify and hereby releases the
Lessor, and his agents, servants and employees, from all liability in connection
with any and all damage to or loss of property, or loss or interruption of
business, or costs and expenses (including, but not limited to attorneys' fees)
occurring to Lessee, its agents, servants, employees, invitees, licensees,
visitors, or any other person, firm, corporation or entity, caused by an fire,
breakage or leakage in any part or portion of the Demised Premises, or from
water, rain or snow that may leak into, issue or flow from any part of the said
Demised Premises, or from the drains, pipes or plumbing work of the same, or
from any place or quarter, unless such loss, interruption, breakage, leakage,
injury or damage be caused by or result from negligent or willful acts or
omissions of the Lessor or his agents, servants and employees.

<PAGE>

ARTICLE 11. FIRE AND OTHER CASUALTY DAMAGE.
           Lessee agrees to give prompt notice to Lessor of any damage or
destruction of and to the Demised Premises by fire or other casualty.
           In the event at least fifty percent (50%) or more of the Improvements
on the Demised Premises are damaged or destroyed by fire or other casualty, and
(ii) such damage or destruction occurs on or after the tenth (10th) anniversary
of the Occupancy Date (unless Lessee has exercised its renewal option under
Article 2 of this Lease, in which event such destruction or damage must have
occurred after the fourteenth (14th) anniversary of the Occupancy Date), Lessor
or Lessee shall have the right to cancel and terminate this Lease by giving
written notice of such election to the other party within thirty (30) days
following the date of said damage or destruction, which notice shall set forth a
date of termination not less than thirty (30) days subsequent to the date of the
notice of termination.
         In the event that this Lease is terminated as aforesaid, the rent shall
abate for the balance of the term, and Lessor shall be entitled to the insurance
proceeds for said damage or destruction and Lessee shall immediately pay to
Lessor the full amount of any policy deductible. If, however, (1) no lection to
terminate as aforesaid is made and this Lease remains in full force and effect,
or (b) the damage is of a lesser nature, Lessor shall restore the Demised
Premises with due diligence, except for delays

<PAGE>

caused by (I) Lessor's inability to obtain materials, (ii) Acts of God, as said
term is legally defined and construed, (iii) strikes, slow downs fire or
weather, (iv) act of governmental authority, or (v) any other cause beyond the
control of Lessor, to substantially the condition existing before such damage or
destruction, with Lessor reserving the right to enter upon the Demised Premises
for such purpose. In such event, the Annual Net Basic Rental shall be equitably
reduced, apportioned or suspended during the period of time required for the
repair or restoration of the Demised Premises, taking into account the
proportion and character (the Building, Improvements, Parking Area, etc.) of the
Demised Premises rendered untenantable by the damage or destruction; provided,
however, that Lessee's performance of all other covenants and agreements by the
Lessee herein to be performed shall not be affected by any such damage or
destruction to the Building on the Demised Premises. Notwithstanding anything in
this Agreement to the contrary, Lessor shall have no obligation to restore and
rebuild if: (I) the Improvements are substantially or totally damaged or
destroyed by a cause or event which is outside the scope of coverage of Lessee's
all risks insurance policy; or (ii) Mellon Bank, N.A. and/or the Allegheny
County Industrial Development Authority shall cause insurance proceeds to be
used to reduce the balance of any outstanding loans given by

<PAGE>

Mellon Bank, N.A. in connection with the Demised Premises
rather than to restore or rebuild.

           All insurance proceeds received due to the damage or destruction of
and to the Demised Premises shall be immediately deposited with the Lessor Or
Mellon Bank, N.A. "in trust" and so as not to be subject to the claims of any
creditor of Lessor. Lessor shall first use such funds for the repair and
reconstruction of the Building and any other damaged potion of the Demised
Premises to the extent required by this Article. In addition, prior to the
commencement of any restoration, rebuilding or repair work, the total estimated
cost of such work, as determined by Lessor, up to the full amount of any
insurance deductible, shall be deposited by Lessee with Lessor.

ARTICLE 12. EMINENT DOMAIN.
            If, during the term of this Lease or any renewal thereof, all or any
part of the Demised Premises shall be taken as a result of the exercise of the
power of eminent domain Lessee shall have the right to claim and prove in such
proceeding and to receive any award which may be made, if any, specifically for
damages or condemnation of the Lessee's movable trade fixtures, equipment and
relocation expenses and the Lessor shall be entitled to the balance of any award
in any such proceeding.
            If the entire Demised Premises shall be taken under such eminent
domain proceeding, this Lease and all the right, title and interest of the
Lessee hereunder shall

<PAGE>

cease and come to an end on the date when possession is taken pursuant to such
proceeding, and the Lessee's obligations to pay annual Net Basic Rental and
other amounts under this Lease shall abate as of said date.
            On a partial taking of the Demised Premises, (a) either Lessor or
Lessee shall have the option to terminate this Lease if (I) at least twenty
percent (20%) of the usable floor area of the Building or (ii) at least fifty
percent (50%) of the parking spaces on the Demised Premises shall be taken in
any such proceeding; and (b) Lessee shall have the option to terminate this
Lease without regard to the potion of the Demised Premises taken in any eminent
domain proceeding) if Lessee provides conclusive evidence that such taking of
the Demised Premises renders the balance of the Demised Premises impractical for
Lessee's business purposes. The Lessor or the Lessee may exercise the aforesaid
option or options to terminate this Lease in its entirety as aforesaid by giving
written notice to the other within sixty (60) days after the date of the vesting
of title in such proceeding, specifying a date not more than thirty (30) days
after the giving of such notice as the date for such terminations; provided,
however, if Lessor is able to provide, for the use of Lessee, its employees and
guests, equivalent parking area or areas within three hundred (300) feet of any
front, side or rear line of the Building or other Improvements, then Lessee's

<PAGE>

aforesaid right to terminate this Lease due to the taking of fifty percent (50%)
of the parking spaces shall thereby end and any notice of termination given by
Lessee to Lessor (due to the taking of said parking spaces) prior thereto shall
be void and of no further force and effect.
            In the event that this Lease is not terminated after the eminent
domain proceeding under the aforesaid provisions, (a) Lessor shall promptly
commence to repair or restore the Demised Premises to tenantable condition for
Lessee's uses and complete same with due diligence except for delays caused by
(I) Lessor's inability to obtain materials, (ii) Acts of God, as said term is
legally defined and construed, (iii) strikes, fire or weather, (iv) act of
government authority, or (v) any other cause beyond the control of Lessor, and
(b) the Annual Net Basic Rental and, correspondingly, the monthly installments
thereof, shall be equitably reduced from and after the date possession is taken
by the condemnor for the balance of the term by taking into account the
character and the amount of the taking.

ARTICLE 13. INTERRUPTION OF USE.
            Except to the extent caused by any negligent or willful act or
omission of Lessor or any employee or agent of Lessor, Lessor shall not be
liable for any damages, compensation or claims of Lessee by reason of (a)

<PAGE>

inconvenience, annoyance, loss of business or interruption in the use of said
Demised Premises to or by Lessee arising from the necessity of repairing or
restoring the Improvements on the Demised Premises at any time during the term
of this Lease or any renewal thereof, whether caused by fire or any other cause,
or (b) the termination of this Lease pursuant to any of the provisions hereof;
provided, however, that Lessor shall use its best efforts to minimize any such
inconvenience, annoyance, loss of business or interruption of use.

ARTICLE 14. REPAIRS.
            The Lessee covenants throughout the term of this Lease at the
Lessee's sole cost and expense, to take good care of the Demised Premises,
including the equipment, fixtures and machinery thereof, and to keep the same in
good order, maintenance, repair and condition; and Lessee agrees to promptly, at
Lessee's sole cost and expense, make all necessary repairs, interior and
exterior, ordinary as well as extraordinary, and foreseen as well as unforeseen,
to the Demised Premises except to the extent that any such repairs are
necessitated because of negligent or willful acts or omissions of Lessor or any
of his employees or agents; provided, however, that Lessor shall be responsible
for making any repairs to the extent that the same are necessitated because of
negligent or willful acts or omissions of Lessor or any of his employees or
agents. The term

<PAGE>

"repair(s)" shall include replacement or renewals when necessary, and all such
repairs shall be equal in quality and class to the original work. At the
termination of this Lease, Lessee shall surrender the Demised Premises in the
same condition as when received, except for reasonable use and natural wear.
            All work done in connection with any maintenance, repairs or
alterations shall be done in a good and workmanlike manner, in compliance with
the applicable building and zoning laws of Shaler Township and with all
applicable laws, statutes, ordinances, regulations, orders and requirements of
all federal, state, county, township, or other governmental authorities having
jurisdiction over the Demised Premises and the appropriate departments,
commissions, boards and officers thereof, and in compliance with the orders,
rules and regulations of the Board of Fire Underwriters or any other body
hereafter constituted exercising similar functions.
            If either party fails or neglects to proceed with due diligence to
commence and complete the repairs, renewals or replacements in accordance with
its obligations hereunder (such party being hereinafter referred to as the
"defaulting party"), the other party, upon the lapse of thirty (30) days after
the mailing of written notice to the defaulting party

<PAGE>

(except (a) where such repairs, renewals or replacements by their nature may
take a longer reasonable specific period of time as agreed to by the other party
in said written notice, and (b) in the event of an emergency, in which event no
such written notice shall be required to Lessee) , may enter upon the Demised
Premises and cause such repairs, renewals or replacements to be made and charge
the cost thereof to the defaulting party. If the Lessee shall be the defaulting
party, such cost shall be deemed to be additional rent. If the Lessor shall be
the defaulting party, Lessor shall, within ten (10) days after written demand by
Lessee , remit such cost to Lessee; in no event , however , shall Lessee have
the right to offset such cost against rent payments.

ARTICLE 15. UTILITIES.

            The Lessee agrees to pay or cause to be paid all charges for gas,
electricity, light, heat or power, water and sewer rental and charges, telephone
or other communication services, and all other utilities servicing and consumed
on the Demised Premises throughout the term of this Lease and to indemnify and
save Lessor harmless against any liability or damages on such account ( except
that Lessor shall reimburse Lessee for the cost on any utility services consumed
by Lessor or his employees and agents). The aforesaid utility services shall be
separately metered for the Demised Premises. From and after the Occupancy Date,

<PAGE>

the Lessee shall at its sole cost and expense procure any and all necessary
additional permits, licenses or other authorizations required for the lawful and
proper installation and maintenance upon the Demised Premises of wires, pipes,
conduits, tubes and other equipment and appliances for use in supplying any
services to and upon the Demised Premises which may be required subsequent to
the Occupancy Date, and Lessor shall comply with reasonable request by Lessee
for Lessor's cooperation or assistance in connection therewith.

ARTICLE 16. TAXES AND ASSESSMENTS.
            The Lessee covenants and agrees to pay, before any fine, penalty,
interest or cost may be added thereto for the nonpayment thereof, all real
estate taxes (including, for so long as the Demised Premises are owned by the
Allegheny County IDA, an amount equal to the ad valorem taxes which would be due
if the Demised Premises were not owned by the IDA), assessments with respect to
the real property comprising the Demised Premises, water and sewer rates and
charges, fire hydrant tax, street lighting tax and other governmental charges,
general and special, ordinary and extraordinary, unforeseen as well as foreseen,
of any kind and nature whatsoever, including but not limited to assessments for
public improvements or benefits which shall during

<PAGE>

the term hereby demised be laid, assessed, levied or imposed upon or become due
and payable upon the Land and the Improvements of the Demised Premises (all of
which real estate taxes, assessments with respect to the real property
comprising the Demised Premises, water and sewer rates and charges, fire hydrant
tax, street lighting tax and other governmental charges are hereinafter,
collectively, referred to as "Impositions") ; provided, however, that, if by law
any such Imposition is payable or may at the option of the taxpayer be paid in
installments (whether or not interest shall accrue on the unpaid balance of such
Imposition), Lessee may pay the same, together with any accrued interest on the
unpaid balance of such Imposition, in installments as the same respectively
become due and payable and before any fine, penalty, interest or cost may be
added thereto for the nonpayment of any such installment and interest. Both
Lessor and/or Lessee shall have the right, jointly and severally, to protest to
the appropriate governmental taxing authority involved, in the lawfully
prescribed manner, any such Imposition and any additional Imposition which may
be levied for imposed on the Demised Premises during the term of this Lease.
            Lessor hereby names, constitutes and appoints Lessee as Lessor's
attorney-in-fact to take, in the name, place and stead of Lessor, any and all
actions which Lessee may deem necessary or appropriate in order to protest any
Imposition or to secure a reduction in the amount of any

<PAGE>

Imposition (including any interest and penalties thereon) which, by the terms of
this Article 16, is payable by the Lessee; and Lessor hereby agrees, promptly
upon the request of Lessee therefor, to execute and deliver to Lessee such other
and further documents as Lessee may reasonably require in order to carry out the
purposes of this Article 16.
            An adjustment shall be made between Lessor and Lessee of all of the
said items included within the term "Impositions" as of the Occupancy Date and
as of the Expiration Date.

ARTICLE 17. INSURANCE.
            During the term of this Lease, Lessee shall obtain, maintain, any
pay the reasonable cost of securing the following insurance coverages in
connection with the Demised Premises: (a) all risks insurance (which insures at
the minimum against the risks covered by a first-class Pennsylvania fire
insurance policy with extended coverage) insuring the Building and other
Improvements on the Demised Premises and the fixtures contained therein in
amounts of not less than 80% of the cost of replacement thereof in substantially
the same condition as existed when the loss occurred, providing for a
"deductible" of not more than $1,000.00 and naming Lessee, Lessor and the
Allegheny county Industrial Development Authority ("ACIDA") as name insureds "as
their interests may appear" and with a mortgagee clause in favor of Mellon Bank,
N.A.; and (b) general public liability insurance against claims for personal
injury,

<PAGE>

death or property damage occurring upon, in or about the Demised Premises, and
such insurance shall afford protection to Lessor, Lessee and the ACIDA to the
limit of not less than $1,000,000.00 in respect to any injury or death to
persons and in respect to property damage; (c) insurance insuring Lessor for
loss of rental income from the Demised Premises during the term of this Lease
due to the occurrence of any hazard, and having a policy limit not less than one
hundred percent (100%) of the Annual Net Basic Rental and Additional Rental
amounts established in this Lease; and (d) insurance against such other risks as
Lessor and Lessee may from time to time deem necessary or advisable or as Lessee
may desire to put into effect, of a similar or dissimilar nature, as are or
shall be customarily covered with respect to buildings similar in construction,
general location, use and occupancy, including, but without limiting the
generality of the foregoing, windstorm, plate glass damage, hail, explosion,
riot and civil commotion, damage from aircraft and vehicles, damage due to
boiler failure, and smoke damage, as and when insurance against such other risks
is available.
            All policies of insurance and renewals thereof shall be subject to
the mutual approval of Lessor and Lessee and shall provide (a) that no material
change or cancellation of said policies shall be made without ten (10) days
prior written notice to Lessor, Lessee, the ACIDA and Mellon Bank, N.A., (b)
that any loss shall be payable notwithstanding any act or omission of the
Lessee, Lessor or the

<PAGE>

ACIDA (of any employee or agent of them) which might otherwise result in the
forfeiture of said insurance, and (c) that the insurance company issuing the
same shall have no right of subrogation against the Lessee, Lessor or the ACIDA.
Lessee and Lessor shall observe and comply with the requirements of all policies
of insurance in effect from time to time with respect to the Demised Premises
and the fixtures and equipment contained therein.
            Lessor and Lessee, respectively, hereby release each other from any
and all liability or responsibility to the other and to anyone claiming through
or under it or them by way of subrogation or otherwise for any loss of or damage
to any property and any injury to or death of any person, to the extent that the
same is covered by any insurance then in effect, even if such loss or damage or
injury or death shall have been caused by the fault or negligence of the other
party or anyone for whom such party may be responsible; provided, however, that
this release shall be applicable and in force and effect only with respect to
any loss or damage or injury or death occurring during such time as the policy
or policies of insurance covering the same shall contain a clause or endorsement
to the effect that this release shall not adversely affect or impair such
insurance or prejudice the right of the insured to recover thereunder.

ARTICLE 18. ASSIGNMENT AND SUBLETTING.
            Lessee shall not have the right to assign this Lease nor to sublet
all or a portion of the Demised Premises

<PAGE>

without the written consent of Lessor, which consent of Lessor will not be
unreasonably withheld. On any subletting consented to by Lessor, (a) the
sublease document must provide that the sublessee agrees to assume all terms,
conditions and obligations of Lessee under this Lease and (b) Lessee shall
remain liable under all terms and conditions of this Lease.

ARTICLE 19. DEFAULT.
            The occurrence of any of the following shall constitute an "event of
default" hereunder:
               (a) Failure of Lessee to take possession of the Demised Premises
within thirty (30) days after the Occupancy Date;
               (b) The vacation or abandonment of the Demised Premises by
Lessee; provided, however, that the cessation of regular business activities at
the Demised Premises shall not constitute an event of default so long as (I)
such cessation does not continue for more than six (6) months, (ii) during such
cessation Lessee continues to maintain the Improvements and the Land in all
respects as if the Demised Premises were being occupied and used for the
purposes contemplated by this Lease, (iii) Lessee undertakes to provide security
services to the Demised Premises (reasonably acceptable to Lessor) so as to
protect the Demised Premises from damage or destruction by vandalism or the
like, (iv) such cessation does not cause cancellation of any

<PAGE>

insurance coverages required by this Lease, and (v) Lessee continues to observe
and perform all other obligations and covenants to which it is subject under
this Lease.
               (c) A failure by lessee to pay (I) any installment of Annual Net
Basic Rental hereunder within fifteen (15) days after the date on which the same
is due, or (ii) any other sum herein required to be paid by Lessee and the same
is not paid within fifteen (15) days from the receipt of written notice that the
same is due;
               (d) A failure by Lessee to observe and perform any other
provision or covenant of this Lease to be observed or performed by Lessee where
such failure continues for thirty (30) days after written notice thereof from
Lessor to Lessee; provided, however, that, if the nature of the default is such
that the same cannot reasonably be cured within such thirty (30) day period,
Lessee shall not be deemed to be in default if Lessee shall within such period
commence such cure and thereafter diligently prosecute the same to completion;
and
               (e) The filing of a petition by or against Lessee for
adjudication as a bankrupt or insolvent or for its reorganization or for the
appointment pursuant to any local, state or federal bankruptcy or insolvency law
of a receiver or trustee of Lessee's property; or an assignment by Lessee for
the benefit of creditors; or the taking possession of the property of Lessee by
any local, state or

<PAGE>

federal governmental officer or agency or court-appointed official for the
dissolution or liquidation of Lessee or for the operating, either temporarily or
permanently, of Lessee's business, provided; however, that if any such action is
com- menced against Lessee the same shall not constitute a de- fault if the same
is dismissed or stayed within sixty (60) days after the filing of the same.

ARTICLE 20. REMEDIES
            Upon the occurrence of any such event of default set forth above in
Article 19:
               (a) Lessor may accelerate all Annual Net Basic Rental payments
due to the balance of the term of this Lease, discounting the same to the then
present value using an interest factor of seven and one-half percent (7-1/2%)
per annum, and declare the same to be immediately due and payable;
               (b) Lessor, at its option, may serve notice upon Lessee that this
Lease and the then unexpired term hereof shall cease and expire and become
absolutely void on the date specified in such notice, to be not less than five
(5) days after the date of such notice; and, thereupon and at the expiration of
the time limit specified in such notice, this Lease and the term hereof granted,
as well as the right, title and interest of the Lessee hereunder, shall wholly
cease and expire and become void in the same manner and with the same force and
effect (except as otherwise

<PAGE>

provided in the last sentence of this paragraph) as if the date fixed in such
notice were the Expiration Date. Thereupon, Lessee shall immediately quit and
surrender to Lessor the Demised Premises, and Lessor may enter into and
repossess the Demised Premises in any lawful manner by summary proceedings,
detainer, ejectment or otherwise and remove all occupants thereof and, at
Lessor's option, any property thereon. No such expiration or termination of this
Lease shall relieve Lessee of its liability and obligations under this Lease,
whether or not the Demised Premises shall be relet;
               (c) Lessor may, at any time after the occurrence of any event
of default, re-enter and repossess the Demised Premises and any part thereof and
attempt in his own name, as agent for Lessee if this Lease not be terminated, or
in its own behalf if this Lease be terminated, to relet all or any part of such
Demised Premises, in a commercially reasonable manner on arms' length basis, for
and upon such terms and to such persons, firms or corporations and for such
period or periods a Lessor, in its sold discretion, shall determine, including a
term beyond the Expiration Date; and Lessor shall not be required to accept any
tenant offered by Lessee or observe any instruction given by Lessee about such
reletting; provided, however, that Lessor shall exercise its best efforts to
mitigate damages. Subject to the foregoing, for the purpose of such reletting,
Lessor may

<PAGE>

reasonably decorate or make reasonable repairs, changes, alterations, or
additions in or to the Demised Premises to the extent reasonably deemed by
Lessor necessary or desirable; an the cost of such decoration, repairs, changes
alterations or additions hall be charged to and by payable by Lessee as
additional rent hereunder, together with any reasonable brokerage and legal fees
expended by Lessor in connection therewith; and any sums collected by Lessor
from any new tenant of the Demised Premises shall be credited
against the balance of the Annual Net Basic Rental and additional rent due
hereunder. Lessee shall pay to Lessor, monthly, on the days when the Annual net
Basic Rental would have been payable under this Lease, the amount due under this
paragraph (c) less the amount obtained by Lessor from such new tenant;
               (d) In the event of a breach or threatened breach by one party of
any of the agreements, conditions, covenants or terms hereof, the other party
shall have the right to invoke any remedy allowed by law or in equity, whether
or not other remedies, indemnity or reimbursements are herein provided. The
rights and remedies provided in this Lease are distinct, separate and cumulative
remedies; and no one of the, whether or not exercised, shall be deemed to be in
exclusion of any of the others;
               (e) In the event of any such default, Lessee hereby empowers any
prothonotary or attorney of any court of

<PAGE>

record to appear for Lessee in any and all actions which may be brought for
Annual Net Basic Rental or additional rent, or other charges or expenses agreed
to be paid by Lessee hereunder, and to sign for Lessee an agreement for entering
into any competent court an amicable action or actions for the recovery of
Annual net Basic Rental, additional rent, or other charges for expenses and, in
said suits or in said amicable action or actions, to confess judgment against
Lessee for all or any part of such Annual Net Basic Rental, additional rent,
including, at Lessor's option, the Annual Net Basic Rental for the entire
unexpired balance of the term of this Lease, computed as set forth in paragraph
(a) of this Article 20, and any other charges, payments, costs and expenses
reserved as rent or agreed to be paid by Lessee, and for interest and costs
together with an attorney's commission of five percent (5%) thereof; provided,
however, that, at least fifteen (15) days prior to the commencement of any suit
or action pursuant to this paragraph (e) of Article 20, Lessor shall give Lessee
written notice of its intention to do so. Said authority shall not be exhausted
by any one exercise thereof, but judgment may be confessed as aforesaid form
time to time and as often as any of said Annual Net Basic Rental, additional
rent or other charges reserved as rent shall fall due or be in arrears, and such
powers may be exercised as well after the expiration of the term of this Lease.
It shall not be

which occurs in the last three (3) months of a lease term or renewal term, then
this Lease shall cease and terminate from the date of such damage and Tenant
shall immediately surrender the Premises to the Landlord who may enter and
repossess the same. If by the exercise of reasonable diligence such damage can
be repaired within thirty (30) days from the date of the occurrence thereof, the
Landlord may enter and repair, and this Lease shall not be affected thereby,
except that if a substantial part of the Premises has been rendered unfit for
occupancy, a just portion of the rent, according to the extend of such damage,

does not interfere in any manner with occupancy by the Tenant of the Premises
herein demised, the rent shall not be apportioned or abated in any way. If said

taking or acquiring and the rent shall be apportioned and paid to such date. The
entire sum awarded for the Premises taken or acquired shall be paid and belong
to the Landlord and shall not be diminished by the value of the leasehold of the
Tenant or any party claiming under or through this Lease.

         Tenant may assign this Lease and/or sublet the whole or any part or
parts of its demised Premises upon receiving the written permission of the
Landlord, which consent shall not be unreasonably held, provided that Tenant

Lease. In the event any assignment of subletting results in Tenant receiving
rent or other related payments in excess of Tenant's financial obligations
hereunder, Tenant agrees to pay to Landlord monthly one-half (1/2) of the amount
by which such payments exceed its financial obligations hereunder.

         18. TRADE FIXTURES

vacates the Premises or otherwise defaults hereunder, to enter and decorate,
remodel, repair, alter or otherwise prepare the premises for re-occupancy. The
exercise of any such reserved right by the Landlord shall not be deemed an
eviction or disturbance of Tenant's use and possession of the Premises and shall
not render Landlord liable in any manner to Tenant or to any other person.

         Landlord covenants that they are seized in fee simple of the leased
Premises; that they have the full right to make this Lease, and that if and so
