DESCRIPTION OF BUSINESS

          Thermatrix Inc. is a global industrial technology company primarily
engaged in the development, manufacture and sale of industrial process equipment
for the destruction of volatile organic compounds and hazardous air pollutants
(collectively, "VOCs"). The core component of the Company's technology is its
proprietary flameless thermal oxidizer ("FTO"), which is capable of treating
virtually all VOCs while achieving destruction removal efficiency ("DRE") of
99.99% or higher with de minimis formation of hazardous by-products such as
                      -- -------
oxides of nitrogen ("NOx"), carbon monoxide ("CO") and products of incomplete
combustion ("PICs"). The Company sells its flameless thermal oxidizer as a
stand-alone unit or as an integrated system.

          The Company has initially focused on the industrial VOC market where
it believes the Company's FTO system offers the greatest economic and
environmental advantages over competing VOC treatment methods. These advantages
include: (i) low operating and maintenance costs; (ii) product safety; (iii)
broad application to a wide range of VOCs, including difficult-to-treat
chlorinated, sulfonated and fluorinated compounds; (iv) the ability to
economically treat fume streams with variable flows and concentrations; (v) high
operating reliability; (vi) high DRE; and (vii) de minimis formation of
                                                -- -------
hazardous by-products.

          The Company has achieved a number of significant milestones in
commercializing its technology, including: (i) establishing the application of
its proprietary FTO technology in the petroleum, chemical/petrochemical, pulp
and paper, medical sterilization and pharmaceutical industries with "market
leader" customers, and for soil and groundwater remediation; (ii) selling more
than 60 commercial-scale systems; (iii) establishing a global sales and
marketing organization; and (iv) the receipt of regulatory approvals by the
Company's customers for the use of the Company's systems in the United States,
Canada, England, Taiwan and France. The Company's customers include: Chevron
U.S.A. Inc., Dow Chemical Company, Chesebrough-Pond's USA Co., Monsanto Company,
FMC Corporation, Formosa Petrochemical Corporation, Mobil Chemical Company, PPG
Industries, Inc., Bayer Corporation and Zeneca, Ltd. as well as the United
States Departments of Defense and Energy (the "DOD" and the "DOE",
respectively).

          The Company's strategy in the industrial VOC market is to: (i)
increase market penetration for established applications; (ii) broaden
application of the Company's proprietary FTO technology for new industrial VOC
applications; and (iii) expand its international operations. In addition to its
core industrial VOC emissions control business, the Company has embarked on a
strategy of working with strategic partners to evaluate the feasibility of
applying the Company's FTO technology for other uses. The Company is presently
exploring the application of its FTO technology to the control of diesel
emissions, treatment of mixed radioactive wastes and destruction of chemical
weapons.

          The Company is also pursuing a strategy to selectively provide
complementary technologies in order to expand its presence in the VOC treatment
market. In April 1996, the Company acquired all rights to the PADRE VOC

                                       2

adsorption technology from Purus, Inc.  The Company sold seven PADRE systems in
1996 and plans to sell PADRE units on a stand-alone basis as well as combined
with Thermatrix systems in the future.


MARKET OVERVIEW

          VOCs are an unavoidable by-product of many manufacturing and process
industries worldwide and must be controlled due to significant health, safety
and environmental risks. The current global market for VOC control equipment
exceeds $2.0 billion and is estimated to grow at 10% per annum according to
McIlvaine & Co., a market analyst firm serving the air pollution control
industry. The primary conventional VOC treatment methods are flame-based thermal
oxidation, activated carbon adsorption and scrubbing systems, which are
installed in many industries, including petroleum, chemical/petrochemical, pulp
and paper and pharmaceutical.

          The health, safety and environmental risks presented by VOCs have led
to significant federal regulations, which are enforced by the Occupational
Safety and Health Administration ("OSHA"), the United States Environmental
Protection Agency ("EPA") and various state and local agencies. Noncompliance
with these regulations carries substantial civil and criminal penalties. The
United States Clean Air Act Amendments of 1990 (the "CAAA") significantly
expanded the scope of air pollution regulations established in the 1970s, and
required the reduction and control of a wide range of air pollutants, including
189 hazardous air pollutants ("HAPs"), most of which are VOCs. The CAAA also
addressed for the first time the reduction of NO\x\that, in combination with
VOCs, produce smog. The CAAA introduced new regulatory requirements and
timetables for the abatement of VOCs and NO\x\ for most geographic areas that
become progressively more stringent through the year 2010.

          International demand for VOC control equipment is rapidly growing.
While many European nations have comprehensive health, safety and environmental
regulations in force, certain Asian and Latin American nations have only
recently begun to recognize the need to more stringently control VOC emissions.
In addition, many multinational companies have recognized the benefits of global
health, safety and environmental standards and are collaborating in the
development of comprehensive future environmental performance standards such as
ISO 14000.


THE THERMATRIX SYSTEM

          The Thermatrix system is a unique proprietary FTO technology for the
destruction of VOCs. The Thermatrix oxidizer is a highly engineered, insulated
vessel packed with ceramic material according to the Company's proprietary
matrix configuration.

          At start-up, the FTO's ceramic matrix is preheated to between 1600 
degrees and 1800 degrees Farenheit. Once the preheating has been completed, a
VOC-laden fume stream along with supplemental air or fuel (as needed) is
introduced into the oxidizer. The fume stream first passes through a mixing
zone, which ensures complete mixing of the VOCs and air or fuel, then through
the reaction zone of pre-heated ceramic material where complete flameless
oxidation occurs in a fraction of a second. The oxidation process releases heat
that is absorbed and conserved by the ceramic matrix, which helps maintain the
temperature of the system without the need for significant supplemental fuel.
Sophisticated process controls monitor the temperature level within the oxidizer
and adjust the supplemental fuel levels in the fume stream to maintain
consistent oxidation temperatures between 1600 degrees and 1800 degrees
Farenheit. Due to its flameless design and consistent temperature profile, the
Company's FTO system achieves high destruction with very low energy usage and
with de minimis formation of NO\x\and CO.
     -- -------
          Depending upon the customer application and operating requirements,
the Company's FTO system can be designed to use natural gas or electricity to
pre-heat the system. In addition, the Company's FTO system can be configured as
a straight-through system, or in cases where the energy content of the fume
stream is low, it can be configured to include an internal heat recovery
process.  The FTO system can also be combined with a heat recovery or material
recycling system from the exhaust gases.

                                       3
<PAGE>
 
          The Thermatrix technology has the following attributes, which
individually or in combination provide direct and indirect cost advantages over
competing VOC treatment methods:

          Energy Efficiency.   The Company's FTO system is energy efficient
          -----------------
because its ceramic matrix absorbs and utilizes the exothermic energy generated
by the oxidation process enabling the system to maintain the required
temperature level for the destruction of VOCs without significant supplemental
fuel. As a result, the Company's FTO system can operate effectively on VOC fume
streams of moderate to high concentrations with less than 30% of the energy
required for many flame-based systems.  This energy efficiency is particularly
significant in geographic locations where the cost of energy is many times
higher than in the United States.

          Cost Efficiency.  The Company's FTO system can be incorporated up-
          ---------------
stream in the customer's process and can be configured, dependent upon the
customer's fume stream, for energy recovery or product recovery.  Due to the
high DRE achieved by the system there is typically no waste generated for
further treatment or disposal.  Since there are no moving parts, on-going
maintenance is minimal and because it is fully automatic there is little
requirement for operator interface.  The combination of these factors leads to a
low overall life cycle cost when compared to other technologies, as supported by
independent demonstrations conducted by the DOD and DOE.

          Safety.   The Thermatrix system is certified for use in flame proof
          ------
areas where conventional flame-based systems are prohibited. Since the Company's
system can be located at the source of VOC emissions, it eliminates the cost of
piping the emissions to remote treatment sites. Destruction at the VOC emission
source also provides a safer and healthier working environment.

          Flexibility.   The Thermatrix system can process a broad range of
          -----------
VOCs, including difficult-to-treat compounds and those with variable flows and
concentrations. This attribute is particularly desirable in industries such as
pharmaceutical manufacturing that utilize batch processing. The Company's FTO
system can typically operate effectively down to 5% of the design fume flow,
whereas flame-based systems generally do not tolerate such wide process
fluctuations and could flame out or suffer reduced destruction efficiencies
under similar conditions.

          Reliability.   The Thermatrix oxidizer is highly reliable because it
          -----------
operates within wide tolerance limits, is fully automatic, has no moving parts,
no catalysts and requires little off-line maintenance.  On-line reliability is
critical because regulatory permits generally require a production line to be
shut down if the emission control device fails.

          Scalability.   The Thermatrix technology can be applied cost-
          -----------
effectively to waste stream flows ranging from one scfm to 15,000 scfm in a
single unit. Larger flows can be treated by installing multiple units with no
loss of efficiency. This scalability allows the same technology and product
design to be standardized over a broad range of flows.

          High DRE.   The Thermatrix system consistently achieves DRE of 99.99%
          --------
or higher, which exceeds the DRE achieved by competing technologies. The high
DRE of the Thermatrix system makes it particularly useful in applications
involving the most toxic and complex VOCs.

          De minimis By-products.   The absence of a flame minimizes the
          ----------------------
formation of by-products generated by flame-based systems, including NO\x\, CO
and PICs. The Company's FTO technology typically achieves thermal NO\x\ levels
not exceeding two parts per million volume ("ppmv") with de minimis PIC and CO
                                                         -- -------
formation.  The reduced energy requirement for the FTO system also results in a
corresponding reduction in the formation of greenhouse gases.

          Regulatory Advantages.   The Company's systems surpass regulatory
          ---------------------
performance requirements because of the high DRE and the de minimis formation of
by-products. The Company's customers have received permits for use of the
Company's FTO system in more than a dozen states, including California, New
Jersey and Texas as well as in Canada, England, Taiwan and France. In addition,
current regulations allow companies to accrue and bank emission credits, which
can be used to offset future mandatory emission reductions. Since the Company's
FTO 

                                       4
<PAGE>
 
technology often exceeds regulatory requirements, its customers are able to
earn emission credits and capitalize on these regulations.


STRATEGY

          The Company seeks to expand the use and application of its proprietary
FTO technology globally and to become a leading supplier of VOC treatment
systems. The Company's strategy in the industrial VOC market is to: (i) increase
market penetration for established applications; (ii) broaden application of the
Company's technology in the industrial VOC market; and (iii) expand its
international operations. In addition, the Company seeks to establish new market
applications for its FTO technology and to selectively provide complementary
technologies in order to expand its presence in the VOC treatment market. Key
elements of the Company's strategy are as follows:

          Increase Market Penetration for Established Applications.   Since
          --------------------------------------------------------
1992, the Company has worked with "market leaders" in targeted industrial
segments to demonstrate that the Thermatrix system can effectively and
economically control VOCs in various industrial applications. Thermatrix systems
have now been successfully installed in the petroleum, chemical/petrochemical,
pharmaceutical and pulp and paper industries, and for soil and groundwater
remediation at facilities operated by customers such as Chevron U.S.A. Inc., Dow
Chemical Company, FMC Corporation and Monsanto Company, as well as facilities
operated by the DOD and DOE. Many of these customers have already purchased
multiple units. The Company is using these reference accounts to promote follow-
on sales to the same customers and to expand sales within these industries.

          Broaden Application of the Company's Technology in the Industrial VOC
          ---------------------------------------------------------------------
Market. The Company is continuing to identify new strategic customers within
- ------
industrial VOC applications not currently served by the Company, such as the
electronics and semiconductor industries.  There is an increasing demand from
customers to supply comprehensive systems that combine the Company's FTO
technology with other technologies.  These "hybrid" systems may provide for
energy recovery or product recovery as well as treatment of the customer's fume
stream.  The Company intends to continue to provide a full range of systems that
provide a fully integrated solution to meet the customer's needs.

          Expand International Operations.   The Company believes that its
          -------------------------------
installed base and proven applications provide a solid foundation for sales and
marketing in both the United States and overseas. In 1994, the Company opened an
office in the United Kingdom and in 1996 expanded its United Kingdom work force
and capabilities to include applications engineering, fabrication, assembly and
service.  The Company has established distribution relationships in Japan,
Taiwan and the People's Republic of China.  In 1997, the Company plans to add
expanded capability in Asia including project management, applications
engineering, and subcontracted vendor support.

          Establish New Market Applications.   In addition to the market for
          ----------------------------------
industrial VOC controls, the Company believes that its innovative FTO technology
may have a competitive advantage in a number of markets. The Company has
embarked upon joint development programs with leading organizations to explore
the application of the Company's FTO technology to the control of diesel engine
emissions, and treatment of radioactive mixed wastes and is seeking a strategic
partner to pursue destruction of chemical weapons.

          Selectively Provide Complementary Technologies.   Customers are
          ----------------------------------------------
increasingly requiring integrated system solutions.  To provide such solutions
the Company seeks to expand its technology portfolio through joint ventures,
selective marketing arrangements and acquisitions. In April 1996, the Company
acquired all rights from Purus, Inc. to a VOC adsorption technology known as
PADRE. The PADRE technology is a recovery technology using a regenerative
synthetic adsorption resin to capture and recover very low concentration VOCs
from low to medium flow vapor streams. In addition to stand-alone sales of PADRE
units, the Company believes the PADRE technology can be combined with the
Company's technology in an integrated system for flows with low VOC content or
where the customer requires destruction rather than recovery of the captured
VOCs.

CURRENT THERMATRIX INDUSTRIAL VOC APPLICATIONS

          The Company has identified industries which are large generators of
VOCs and where it believes its FTO technology provides significant competitive
advantages over existing treatment methods. The Company has sought acceptance of
its systems in each of its initial target markets through the utilization of
"market leader" customers. To date, the Company has sold over 60 systems across
a range of industries including petroleum, chemical/petrochemical,
pharmaceutical, pulp and paper manufacturing, medical sterilization and for soil
and groundwater remediation. The following table sets forth the Company's target
markets, representative customers and the types of VOCs treated by its systems:

</TABLE>

          Petroleum.   The petroleum industry is a large generator of VOCs.
          ---------
These VOCs are released into the environment from a multitude of sources,
including marine terminals, unit process operations and fugitive emissions from
hundreds of small sources (for example, pumps and valves). Petroleum refineries
also generate significant volumes of oily waste water across their various
processes. Recent Federal regulations regarding benzene in waste water have
resulted in mandates to achieve acceptable emission levels for control devices
used to process any vapor phase emissions from oil/water separation. These
processing units are often located in flammable areas and require all adjacent
process equipment to be certified for operation in flame proof areas.

          The primary advantages of the Company's technology as applied to the
petroleum industry includes cost effectiveness and its high DRE, which minimizes
the need for secondary hazardous waste disposal and may enable customers to
receive regulatory emission credits, and the ability to treat VOC emissions at
their source in flame proof environments.

          Chemical/Petrochemical.   The chemical/petrochemical industries are
          ----------------------
two of the largest generators of complex VOCs, including those containing
chlorinated, fluorinated and sulfonated compounds. Thousands of industrial
facilities within these industries manufacture a wide range of organic
chemicals, including plastics, paints, solvents, pesticides and fertilizers.
Most conventional VOC treatment methods have limited ability to treat these
complex organic compounds.

          The Company believes that its technology is cost effective and
particularly well-suited for the treatment of certain hydrocarbons and other
hard-to-treat VOCs given its ability to deliver high DRE with de minimis
formation of by-products such as NO\\X\\, CO and PICs. Further, the Company's
FTO systems are designed to withstand corrosive by-products, which may
contaminate catalytic destruction systems and shorten the lives of other
treatment systems.

          Pharmaceutical.   The pharmaceutical industry uses large volumes of
          --------------
chlorinated hydrocarbons in the manufacture of pharmaceuticals, including drug
intermediates, and personal care products. The industry typically utilizes batch
processes employing a broad range of compounds within the same manufacturing
facility. Due to the 

                                       6
<PAGE>
 
highly toxic properties of many of the elements used in the pharmaceutical
manufacturing process, these firms demand reliable systems with the ability to
handle a wide variety of toxic waste streams in varying flows and
concentrations.

          The primary advantages of the Company's technology as applied to the
pharmaceutical industry are its high DRE, on-line reliability and ability to
deal safely with a variety of compounds.

          Pulp and Paper.   Paper production uses the kraft process, which
          --------------
generates VOCs from the cooking liquor used to dissolve the organic binder
material in wood chips. The economics of the kraft process require recovery and
reuse of the spent cooking chemicals and recovery of the heat content of the
concentrated spent liquor. This chemical and energy recovery is typically
accomplished through combustion, which generates large volumes of flue gases
containing significant concentrations of malodorous sulfonated compounds.

          The Company has developed an application for its technology which has
been demonstrated to be more effective than conventional methods in removing
these sulfonated compounds and reducing the unpleasant odor often associated
with the kraft process.

          Medical Sterilization.   Ethylene oxide is a highly potent fumigant
          ---------------------
used by commercial sterilization facilities and hospitals to sterilize medical
devices. Since the off-gas from these sterilization facilities is extremely
toxic and flammable, it demands a treatment system with a high DRE. There are
currently over 100 such sterilization facilities across the United States that
will be required to install abatement systems within the next few years.

          The primary advantages of the Thermatrix technology as applied to the
medical sterilization industry include its flameless nature and high DRE. Sorex
Medical, a large contract sterilizer, selected the Thermatrix system because of
its inherent safety, low capital and maintenance costs, high DRE and on-line
reliability when compared with the traditional treatment methods, catalytic
oxidation and wet scrubbers.

          Soil and Groundwater Remediation.   The soil and groundwater
          --------------------------------
remediation market continues to seek proven, low cost, expedient solutions. The
Company has sold eight FTO units and six PADRE systems for soil and groundwater
remediation, including units in facilities owned by DOD, DOE, Thermo Remediation
Inc., Envirogreen Technologies, Ltd., and a unit in association with an in-situ
thermal desorption technology for a PCB contaminated site. The DOE conducted an
independent demonstration at Savannah River to compare the performance of flame-
based destruction systems, catalytic oxidizers and the Company's FTO technology.
The results of the demonstration showed that, for the fume streams demonstrated,
the life cycle cost of the Company's FTO technology was less than one-third that
of the other technologies and that the Company's system achieved significantly
higher DRE. The DOD has also conducted a similar demonstration at McClellan Air
Force Base in Sacramento, California with cost savings of almost 20% compared to
the alternate technology.


POTENTIAL APPLICATIONS UNDER DEVELOPMENT

          In addition to its core industrial VOC emissions control business, the
Company has embarked on a strategy of working with strategic partners to
evaluate the feasibility of applying the Company's FTO technology for other
uses.

          Diesel Engine Emission Control.   The fume and soot emissions from
          ------------------------------
static and mobile diesel engines create a serious environmental problem for
which there is currently no cost-effective solution. The Company is
collaborating with a leading supplier of automotive and aerospace components to
test the feasibility of the Company's FTO system to treat diesel emissions.  The
Company delivered a prototype unit in late 1996 which was fitted to a diesel
engine test bed.  Tests have been conducted with varying diesel injection
scenarios to test the ability of the system to handle a range of particulate
sizes and VOC emissions.  Initial test results received in 1997 have been
encouraging and the Company intends to conduct further development activity.

          Radioactive Mixed Wastes.   Mixed wastes are comprised of radioactive
          ------------------------
wastes and organic chemical wastes. The treatment objective is to remove and
destroy the organic materials in order to reduce the waste volume prior to

                                       7
<PAGE>
 
landfilling or encapsulation, vitrification or stabilization of the radioactive
components for final disposal or storage.  In October 1996, the Company
announced the formation of Formatrix, LLC ("Formatrix"), a joint venture with
ThermoChem, Inc., a Maryland-based leader in steam reforming systems.
Formatrix, LLC will combine, under license, the patented technologies from
Thermatrix and ThermoChem to create a treatment system for significantly
reducing the volume of the radioactive wastes prior to their encapsulation or
vitrification for long-term burial.  Formatrix, LLC will initially focus on
treating radioactive wastes from spent ion exchange resins.  A prototype
Thermatrix-ThermoChem system has been constructed under a contract with the DOE
and has successfully treated a number of non-radioactive surrogate mixed wastes.

          Chemical Demilitarization.   Chemical demilitarization refers to the
          -------------------------
safe disassembly and destruction of stockpiled chemical warfare agents.
Government programs are currently underway in both the United States and
overseas to develop techniques to safely destroy chemical warfare agents such as
mustard gas and nerve agents. The chemical makeup of many of these agents,
particularly mustard gas, is similar to compounds that the Company is currently
destroying in the commercial industrial market.  The Company is seeking a
strategic operating partner to pursue this market.

          The engineering challenges involved in treating diesel emissions,
radioactive mixed wastes and chemical warfare agents are different in a number
of respects from the conditions in which the Thermatrix system has been used in
the past, and there can be no assurance that the Thermatrix technology will
prove successful in any of these new applications.


SALES AND MARKETING

          The Company has established a network of independent commissioned
sales representatives. The Company currently has agreements with 17
representative organizations with over 50 sales agents selling the Company's FTO
system throughout the United States and Canada. The representative organization
network was established to introduce the technology by utilizing the long-
standing relationships and selling experience of the independent representatives
with the Company's target customer base.

          All independent representatives are paid solely on commission, which
is calculated on a sliding scale as a percentage of sales revenues. The
representative organization is established geographically and is managed by four
in-house Regional Sales Directors. These regional sales directors typically hold
science or engineering degrees and have an average of 14 years of industrial
selling experience. Responsibility for pricing and terms and conditions is
retained by the Company. Regional sales offices are located in: Naperville,
Illinois; Westford, Massachusetts; Houston, Texas; and Lakewood, Colorado.
Sales to government agencies are handled directly by the Company.

          In order to manage the growing global interest in the technology, the
Company established a London office in 1994, which employs six people and
handles sales and technical support directly for the European market. In 1995,
the Company entered into representative agreements with ICI Taiwan Limited and
ICI Japan Limited for sales representation in Taiwan and Japan, respectively.
In 1996, the Company expanded its coverage in Asia to include the Peoples'
Republic of China and signed a three-way agreement with ICI Japan Limited and
Toray Engineering Co. to include support for engineering, assembly, installation
and commissioning services in Japan.


RESEARCH AND DEVELOPMENT

          Fundamental research and development of the Company's FTO technology
began as part of a research program conducted by the DOE to find ways to extract
energy from oil shale. Research in the technology has been conducted by the DOE
at the Lawrence Livermore National Laboratory and subsequently by the Company
over a twelve-year period. Since 1992, the Company's research and development
has focused primarily on the development of applications for its FTO technology
as a thermal destruction process for the treatment of VOCs.  In 1996, the
Company expanded its development activities to include engineering improvements
to the existing PADRE technology and development of a hybrid system utilizing
both FTO and PADRE.

                                       8
<PAGE>
 
          The research and development group consists of three technical program
managers led by Dr. Richard J. Martin, Director of Technology and one of the key
developers of the technology. The group has two primary missions: (i) to
optimize the Company's technology for new applications in the industrial VOC
control market, and (ii) to support the technology development for new market
applications such as diesel emission control, radioactive mixed waste treatment
and chemical demilitarization. When areas of specialized expertise are required,
such as advanced metallurgy, the Company relies on consulting and collaboration
relationships with SRI International.

          The Company maintains six transportable demonstration units that are
deployed around the world to demonstrate and optimize the technology on actual
VOC fume conditions.


INTELLECTUAL PROPERTY

          As of February 28, 1997, the Company owned seven United States and
seven international patents, had received notice of allowance for three
additional United States patent applications and two additional international
patent applications, and had an additional five United States and 25
international patent applications pending relating to its thermal treatment
technology. All issued United States patents expire during the period between
July 31, 2005 and February 11, 2014. The Company has granted a license of its
patents to Formatrix, LLC, a joint venture 40% of which is owned by the Company,
for restricted use in the field of low level radioactive spent ion exchange
resins.

          The Company's ten issued and allowed United States patents include
several hundred claims of varying scope relating to many of the Company's
inventive methods and apparatuses. These patents cover fundamental aspects of
flameless thermal oxidation that are the bases of the Company's technology and
their application. Aspects of the technology, including the use and maintenance
of a "flameless reaction wave" of gases or vapors in a matrix of heat resistant
materials, are covered under a variety of claiming formats.

          In addition to patents, the Company relies on trade secrets and
proprietary know-how, which it seeks to protect, in part, through appropriate
confidentiality and proprietary information agreements. The confidentiality and
proprietary information agreements generally provide that all confidential
information developed or made known to individuals by the Company during the
course of the relationship with the Company is to be kept confidential and not
disclosed to third parties, except in specific circumstances. The agreements
also generally provide that all inventions conceived by the individual in the
course of rendering services to the Company shall be the exclusive property of
the Company.

          In addition to the foregoing patents and patent applications, the
Company has three issued United States trademarks, and has an additional two
United States and four international trademark applications pending for certain
of the Company's tradenames and other intellectual property.


ENGINEERING AND MANUFACTURING

          The Company's engineering and manufacturing operations are based in
Knoxville, Tennessee and are organized under a comprehensive project management
system, including project costing, process design and engineering, procurement,
system assembly, pre-testing, installation and commissioning.

          The Company has focused on modularizing and standardizing components
of its technology and utilizes sophisticated software to integrate these
components into comprehensive air pollution control systems. This systems
integration expertise allows the Company to provide comprehensive systems
centered around the Company's FTO technology. The engineers utilize state-of-
the-art, PC-based, computer-aided engineering and database management tools,
including three-dimensional design tools. The Company believes this approach to
automating the design process drives down costs by: (i) optimizing the
engineering work effort and allowing ready access to the growing inventory of
standardized design data; (ii) contributing significantly to accuracy,
completeness and efficiency in the manufacturing continuum (design--
procurement--fabrication--assembly);

                                       9
<PAGE>
 
(iii) shortening the Company's product delivery cycle; and (iv) facilitating the
handling of design data between the Company, its subcontractors and its clients.

          The systems are typically assembled, wired and tested prior to
delivery and installation. The Company manufactures its systems to customer
order. Component fabrication is carried out using qualified subcontractors
specializing in the manufacture of the particular component. These specialized
subcontractors adhere to and carry formal certification with national and
international codes and standards such as those of the American Society of
Mechanical Engineers (ASME). The Company's subcontractors have been selected to
allow the Company to expand its capacity to manufacture additional systems while
minimizing the Company's investment in fixed costs. The Company uses qualified
subcontractors throughout the United States and overseas and is not dependent on
any one or subset of these subcontractors.

          In the fabrication process, no one subcontractor is exposed to the
entire technology package and final assembly of the systems is completed
directly by the Company or a separate subcontractor. Throughout the delivery
cycle, the manufacturing process is managed to conform with ISO 9000.

          During the period that the technology was developed, an extensive
empirical database of performance characteristics for waste flows of different
volumes and compositions was compiled. The Company has used this database to
develop a proprietary, software-based design tool. In the design process, the
software tools analyze the characteristics of the customer's fume flow and
determine the optimal system configuration and size. Not only does this process
specify the correct system characteristics, but it automates the task of
generating budget proposals. The Company is continuing to expand this database
as new systems are installed.


COMPETITION

          The industrial VOC control equipment market is mature and highly
fragmented among a large number of competitors, none of whom have a significant
industry-wide market share. The Company currently competes primarily with
suppliers of flame-based thermal oxidation systems, carbon adsorption systems
and scrubbing systems. Within each of these categories, the technologies are
generally undifferentiated and characterized by commodity pricing.  Since many
of these technologies have been in use for over thirty years, they have certain
advantages. These technologies are familiar and predictable to companies
requiring VOC controls and to regulators, and are available from and promoted by
a large number of suppliers. Some of the Company's competitors have
substantially greater financial resources, operating experience and market
presence than the Company. There can be no assurance that the Company's existing
competitors or new market entrants will not develop new technologies or
modifications to existing technologies that are superior to or more cost-
effective than the Company's FTO technology. In addition, increased competition
could result in price reductions and reduced gross margins and could limit the
Company's market share.

          The Company believes that the major considerations in selecting
industrial VOC control systems are: safety; capital, operating and maintenance
costs; ease of permitting; process stream characteristics; unit location; and
on-line reliability. The Company believes it competes favorably with respect to
these factors.


REGULATION

          VOCs are an unavoidable by-product of many manufacturing and process
industries worldwide and must be controlled due to the significant health,
safety and environmental risks.  Many of these VOCs are flammable, explosive or
highly toxic.  To control these significant health and safety risks, regulations
have been promulgated and enforced in the United States and overseas.  These
regulatory requirements are expanding globally into developing nations.

          The United States Clean Air Act Amendments of 1990 (the "CAAA")
significantly expanded the scope of air pollution regulations established in the
1970s, and required the reduction and control of a wide range of air pollutants,
including 189 hazardous air pollutants, most of which are VOCs. The CAAA also
addressed the 

                                       10
<PAGE>
 
reduction of NO\x\ that, in combination with VOCs, produce smog. The CAAA
introduced new regulatory requirements and timetables for the abatement of VOCs
and NO\x\ for most geographic areas that become progressively more stringent
through the year 2010. Specifically, Title I and Title III of the CAAA address
emissions of VOCs. Principal provisions of these titles are discussed below.

          Title I establishes requirements for attaining and maintaining
national ambient air quality standards ("NAAQS"). Key provisions of Title I are
aimed at bringing cities and other areas which are not in attainment in line
with NAAQS in most areas by the year 2000 and all cities by 2010. In addition,
measures for all regions require the application of technological controls to
reduce emissions of ozone precursors, such as VOCs, from a broad range of
industrial activities, including consumer solvents and coatings, hazardous waste
treatment storage and disposal facilities, solid waste landfills and marine
terminal loading and unloading.

          Title III establishes a new program for the regulation of toxic air
pollutants. The combined federal and state program provided for in the
legislation creates a comprehensive and coordinated nationwide effort to deal
with these pollutants. Title III specifically lists 189 substances as hazardous
air pollutants, of which most are VOCs. Title III defines three significant
programs that will require substantial pollution control expenditures by
industry across the nation: (i)  control of routine releases of air toxins from
major industrial and commercial sources; (ii) control of air toxic releases from
area sources, primarily in urban areas; and (iii) control of accidental releases
of air toxins from industrial and commercial sources. To reduce emissions of the
189 listed toxic hazardous air pollutants, the application of the maximum
achievable control technology at major air emitting sources may be required.

          The Company works with regulatory agencies both domestically and
overseas to inform these agencies about the Company's FTO technology in order to
facilitate the permitting process for its customers. In England, Her Majesty's
Inspectorate of Pollution has issued Technical Note ITN/IPCX/02 identifying the
flameless oxidation process benefits of high destruction (greater than 99.99%)
and low formation of NO\x\ and CO. The Company's FTO system was selected for
inclusion in the Texas Natural Resource Conservation Commission list of
innovative environmental technologies. Thermatrix is currently under review for
certification by the California Environmental Protection Agency ("CalEPA") as a
flameless thermal destruction technology. The CalEPA program is closed to
incineration technologies.


EMPLOYEES

          As of February 28, 1997, the Company had 61 full-time employees, 17 of
whom hold advanced degrees. The Company believes that it has been successful in
attracting experienced and capable engineering, operations and management
personnel. None of the Company's permanent, full-time employees is covered by
collective bargaining agreements.


RISK FACTORS

          Operating Losses and Accumulated Deficit; Uncertainty of Future
          ---------------------------------------------------------------
Profitability.   The Company had a net loss of approximately $4.9 million in
- -------------
1996, and had an accumulated deficit of approximately $27.1 million at December
31, 1996. Since 1992 when the Company restructured its operations, the Company
has financed its operations primarily through private placements of equity
securities totaling approximately $20.3 million, an initial public offering of
its common stock with net proceeds totaling approximately $22.1 million, and a
credit facility with its bank of $4.0 million. The Company does not expect to be
profitable unless and until sales of its FTO systems generate sufficient
revenues to fund its operations. There can be no assurance that the Company will
achieve such revenues.

          Uncertainty of Market Acceptance.   To date, FTO systems have been
          --------------------------------
installed in a small segment of a number of industries.  There can be no
assurance that the Company's FTO technology will receive broad market acceptance
as an economically and environmentally acceptable means of destroying VOCs.
Broad market acceptance of the Company's products will depend upon the Company's
ability to persuade potential customers to 

                                       11
<PAGE>
 
adopt its FTO technology in place of certain, more established, competing
technologies, including flame-based destruction and carbon adsorption systems.
The failure of the Company to persuade a significant number of potential
customers to adopt its FTO technology would have a material adverse effect on
the growth of the Company's business, results of operations and financial
condition.

          Sensitivity to Major Projects.  In 1996, three projects accounted for
          -----------------------------
38% of the Company's revenues and in 1995, two projects accounted for 59% of the
Company's revenues. Although the Company is expanding the number of its
customers and installations, the average size and dollar volume of each
installation has been increasing. As a result, the Company's results of
operations are likely to continue to be dependent on major projects. Such a
reliance on major orders is likely to lead to fluctuations in, and to reduce the
predictability of, quarterly results. Larger projects also pose other
challenges. The sales cycle for larger projects tends to be longer than for
smaller projects, and, when orders are received, projects may be delayed by
factors outside the Company's control, including customer budget decisions,
design changes and delays in obtaining permits. Also, because the dollar volumes
are larger, the costs of providing warranty services could increase. The
Company's business, results of operations and financial condition could be
materially adversely affected if the Company were to fail to obtain major
project orders, if such orders were delayed, if installations of such systems
were delayed, or if such installations encountered operating, warranty or other
problems.

          Fluctuations in Quarterly Operating Results.   The Company's quarterly
          -------------------------------------------
revenues and operating results have varied significantly in the past and may
fluctuate significantly in the future as a result of a variety of factors, many
of which are outside the Company's control. Such factors include general
economic and industry conditions, the size and timing of individual orders, the
timing and amount of project change orders, the introduction of new products or
services by the Company or its competitors or the introduction of the Company's
products to new markets, changes in the levels of operating expenses, including
development costs, and the amount and timing of other costs relating to the
expansion of the Company's operations.

          Furthermore, the purchase of the Company's products, particularly for
major projects, may involve a significant commitment of capital, with the
attendant delays frequently associated with large capital expenditures and
authorization procedures within its customers' organization. For these and other
reasons, the sales cycle for the Company's products can be lengthy (up to two
years) and subject to a number of significant risks over which the Company has
little or no control, including customer budgetary constraints. The Company
historically has operated with little backlog because most customer orders are
placed with relatively short lead times, usually from four to twenty-four weeks.
Variations in the timing of recognition of specific revenues due to changes in
project scope and timing may adversely and disproportionately affect the
Company's operating results for a quarter because the Company establishes its
expenditure levels on the basis of expected future revenues, and a significant
portion of the Company's expenses do not vary with current revenues.

          Management of Growth.   The Company's revenues increased from $6.5
          --------------------
million in the year ended December 31, 1995 to $13.6 million in the year ended
December 31, 1996. The Company's growth has placed, and could continue to place,
a significant strain on its managerial, operational and financial resources.
Although it relies on subcontractors to fabricate subassemblies and to assemble
and install completed systems, the Company uses its own employees to design,
test and commission systems. The Company seeks to maintain engineering and
design staffing levels adequate for current and near-term demand. During periods
of rapid growth, such as that experienced by the Company during the last year,
the Company's engineering and design personnel generally operate at full
capacity. As a result, future growth, if any, is limited by the Company's
ability to recruit and train additional engineering, design and project
management personnel and by the ability and performance of the individual
employees in managing more and larger projects. Furthermore, any failure to
maintain quality or to meet customer installation schedules could damage
relationships with important customers, damage the Company's reputation
generally and result in contractual liabilities.  There can be no assurance that
the Company will be able to effectively manage an expansion of its operations or
that the Company's systems or controls will be adequate to support the Company's
operations if expansion occurs. In such event, any failure to manage growth
effectively could have a material adverse effect on the Company's business,
results of operations and financial condition.

          Risks Associated with International Operations and Sales.   The
          --------------------------------------------------------
Company plans to increase its revenues, in part, through an expansion of its
overseas operations. International sales and operations may be limited or

                                       12
<PAGE>
 
disrupted by the imposition of government controls, export license requirements,
trade restrictions, changes in tariffs, difficulties in staffing, the transport
of machinery, managing international operations and other factors.  Expansion
internationally encompasses the need to provide an infrastructure for
operations, sales and administration.  There can be no assurance that the
Company will be able to attract, hire and train personnel or develop the
infrastructure needed on a timely basis which may have an adverse impact on the
Company's business, results of operations and financial condition.  Regulatory
compliance requirements differ among foreign countries and are also different
from those established in the United States. If the Company's customers are
unable to obtain the necessary foreign regulatory approvals on a timely basis,
the Company's international sales, and thereby its business, results of
operations and financial condition, could be materially adversely affected.
Additionally, the Company's business, results of operations and financial
condition may be materially adversely affected by fluctuations in currency
exchange rates as well as increases in duty rates, difficulties in obtaining
export licenses, ability to maintain or increase prices and competition. The
Company denominates international sales in either United States dollars or local
currencies. Sales in Europe have been primarily denominated in pounds sterling.
Since some expenses in connection with international contracts are often
incurred in United States dollars, there can be a short-term exchange risk
created. If the Company has significant international sales in the future
denominated in foreign currencies, the Company may purchase hedging instruments
to mitigate the exchange risk on these contracts.

          Risks Associated with Commercialization of Technology.  As the
          -----------------------------------------------------
Company's technology has become more accepted, the Company has been selling
increasingly larger systems. Larger systems are generally distinguished by the
size and weight of the system and the characteristics of the waste stream flow.
The operating history of the larger units is shorter, and the larger systems are
generally more complex than the initial systems installed by the Company.
Consequently, there can be no assurance that the performance of the Company's
units will not deteriorate as the units age or that unanticipated problems will
not be encountered with the larger, more complex systems. Any deterioration of
the Company's units or unanticipated problems with its systems could have a
material adverse effect on the Company's business, results of operations and
financial condition.

          Proprietary Technology and Unpredictability of Patent Protection.
          ----------------------------------------------------------------
The Company relies on patents, trade secrets and proprietary know-how, which it
seeks to protect, in part, through appropriate confidentiality and proprietary
information agreements with its strategic partners, employees and consultants.
There can be no assurance that the proprietary information or confidentiality
agreements will not be breached, that the Company will have adequate remedies
for any breach, or that the Company's trade secrets and proprietary know-how
will not otherwise become known to or be independently developed by others.

          Uncertainty of Regulatory Acceptance.   The Company's customers are
          ------------------------------------
required to comply with environmental laws and regulations in the United States
and elsewhere which limit the emission of VOCs and other chemicals. Such
environmental laws and regulations also restrict the methods which companies may
use to reduce or eliminate toxic emissions and often require the permitting of
emission control equipment. The Company believes that its FTO technology does
not come under the United States Environmental Protection Agency's ("EPA")
current definitions of incineration. Classification as an incineration
technology could significantly increase the length of time and cost of the
permitting process for customers because of the requirement for a public
hearing, especially where community sentiment is opposed to incineration
technology. There can be no assurance that the EPA will not classify the
Company's FTO technology as an incineration technology in the future or that
there will not be other federal, state or foreign regulatory developments that
increase the regulatory burden on the Company's customers, including
requirements for more extensive permitting, in order to utilize the Company's
systems. A lengthier permitting process could reduce the competitive advantages
of the Company's technology and materially adversely affect the Company's
business, results of operations and financial condition. In addition, the level
of enforcement activities by environmental protection agencies and changes in
laws and regulations will also affect demand for the Company's systems. To the
extent that certain VOCs are banned or lower cost substitutes that are not
subject to regulation are developed for some or all of the VOCs currently
generated in the Company's markets, such bans or developments could materially
adversely affect the demand for the Company's systems. To the extent that the
burdens of complying with such environmental laws and regulations may be eased,
the demand for the Company's systems could be materially adversely affected. In
addition, the existence of environmental regulations and the level of
enforcement vary by country and may affect the Company's ability to sell its
systems outside the United States.

                                       13
<PAGE>
 
          Dependence on Key Personnel.   The Company's success depends to a
          ---------------------------
significant extent upon its executive officers, particularly its Chairman,
President and Chief Executive Officer, John T. Schofield, and key engineering,
sales, marketing, financial and technical personnel. Employees may voluntarily
terminate their employment with the Company at any time, and none of the
Company's employees is subject to any term employment contract with the Company.
Because the Company is still at an early stage of growth, the Company has
limited personnel resources available to address the different activities in its
business. The loss of the services of one or more of the Company's key employees
could have a material adverse effect on the Company's business, results of
operations and financial condition. The Company maintains key employee life
insurance on the life of John T. Schofield in the amount of $2,000,000. There
can be no assurance that such amount will be sufficient to compensate the
Company for the loss of the services of such individual.

          The Company also believes that its future success will depend in large
part upon its ability to attract and retain additional highly skilled personnel,
particularly design and process engineers. Because of the technical
sophistication of the Company's systems and the sophisticated engineering
software utilized by the Company, design and process engineers who join the
Company generally are required to have advanced technical knowledge and
significant training to perform efficiently and productively. The availability
of such personnel is limited, and the Company has at times experienced
difficulty in locating new employees with the requisite level of expertise and
experience. There can be no assurance that the Company will be successful in
retaining its existing key personnel or in attracting and retaining the
personnel it requires in the future

          Risks Associated With Development Programs.   In addition to its core
          ------------------------------------------
industrial VOC emissions control business, the Company has embarked on a
strategy of working with strategic partners to evaluate the feasibility of
applying the Company's FTO technology for other uses. In collaboration with
strategic partners, the Company has begun tests involving diesel emission
control, radioactive mixed waste treatment and chemical weapons destruction.
The engineering challenges involved in treating diesel emissions, radioactive
mixed wastes and chemical warfare agents are different in a number of respects
from the conditions in which the Thermatrix system has been used in the past,
and there can be no assurance that the Thermatrix technology will prove
successful in any of these new applications. Moreover, the Company's extensive
database of test results which it uses to design systems for individual
installations may not be relevant to these new applications. If early tests of
any of these new applications are positive, the Company may need to engage in
extensive and costly applications development and engineering in order to
commercialize its system for such use, and there can be no assurance as to the
success of any such effort.

          Dependence on the Reliability and Performance of Subcontractors.   The
          ---------------------------------------------------------------
Company relies on subcontractors to build system components and to assemble and
install systems. The Company's ability to deliver high quality systems on time
will depend upon the reliability and performance of its subcontractors. The
failure of a subcontractor to meet delivery schedules could cause the Company to
default on its obligations to its customers, which could materially adversely
affect the Company's reputation, business, results of operations and financial
condition. In addition, the Company's reliance on subcontractors for
manufacturing, assembly and installation places a significant part of the
Company's quality control responsibilities on these subcontractors. There can be
no assurance that the Company will be able to continue to contract for the level
of quality control required by the Company's customers. The failure to provide
such quality control could result in manufacturing and installation delays which
could have a material adverse effect on the Company's business, results of
operations and financial condition.

          Possible Product Liability.   The Company's FTO systems are designed
          --------------------------
to destroy VOCs, which are highly toxic and flammable. If the Company's systems
are improperly designed or operated outside of design parameters and operating
instructions provided by the Company, there is a risk of system failure or
release of VOCs, which could require the Company to defend itself against a
product liability or personal injury claim. Although the Company has product
liability and commercial general liability insurance in scope and amount which
it believes to be sufficient for the conduct of its business, there can be no
assurance that such insurance will cover or be adequate to cover such claims. In
addition, the Company's general liability insurance is subject to coverage
limits and excludes coverage for losses or liabilities relating to environmental
damage or pollution. Accordingly, the Company's efforts to defend itself against
such claims could have a material adverse effect on the Company's business,
results of operations and financial condition.

                                       14
<PAGE>
 
          Dependence on Customer Information.   The Company is highly dependent
          ----------------------------------
upon information provided by its customers concerning the type, volume and flow
rate of VOC emissions to be treated by the Company's systems. If the customer's
information is inaccurate, a malfunction in the Company's FTO system could
occur, resulting in damage to the customer's facilities or personal injury. In
addition, incorrect information could cause delays in the design, manufacture
and installation of the customer's system. Through no fault of its own, the
Company could then be held liable for damages resulting from such malfunction or
delay. Any of these factors could have a material adverse effect on the
Company's business, results of operations and financial condition.

          Potential Environmental Liability.    Although the Company does not
          ---------------------------------
believe that its activities would directly expose it to liabilities under local,
state or federal environmental laws and regulations, if the Company were to
improperly design, manufacture or test its systems or fail to properly train its
customer's employees in the operation of the systems, it could be exposed to
possible liability for investigation and clean-up costs under such environmental
laws. Although the Company does not currently lease its systems to customers or
operate the systems on behalf of its customers, if it were to do so in the
future, the Company could be liable under environmental laws for any releases of
hazardous substances.

          The Company generally conducts performance tests on its systems at its
customers' facilities. However, in the future the Company may perform prototype
testing in its own facilities. If such testing were to involve hazardous
substances, it could subject the Company to liability under environmental laws
and regulations.

          Under some environmental laws and various theories of tort and
contract law, it is also possible that the Company could be liable for damages
to its customers and third parties resulting from the actions of its customers
or arising from the failure or malfunction, or the design, construction or
operation of, the Company's FTO systems or products, even if the Company were
not at fault. The Company's general liability insurance is subject to coverage
limits and generally excludes coverage for losses or liabilities relating to or
arising out of environmental damage or pollution. The Company's business,
results of operations and financial condition could be materially adversely
affected by an uninsured or partially insured claim.

          Risks Associated with Fixed Price Contracts.   A majority of the
          -------------------------------------------
Company's contracts are performed using "fixed-price" rather than "cost-plus"
terms. Under fixed-price terms, the Company quotes firm prices to its customers
and bears the full risk of cost overruns caused by estimates that differ from
actual costs incurred or manufacturing delays during the course of the contract.
Some costs, including component costs, are beyond the Company's control and may
be difficult to predict. If manufacturing or installation costs for a particular
project exceed anticipated levels, gross margins would be materially adversely
affected, and the Company could experience losses. In addition, the
manufacturing process may be subject to significant change orders. However, the
cost of these change orders may not be negotiated until after the system is
installed. The failure of the Company to recover the full cost of these change
orders could materially adversely affect gross margins and also cause the
Company to experience losses.


ITEM 2.    PROPERTIES

          The Company leases approximately 5,000 square feet of office space in
San Jose, California under a three-year lease with a two-year renewal option,
which the Company uses as its research and development, bid and proposal and
corporate administrative offices. The Company has a remaining three-year lease
for approximately 15,000 square feet of office space in Knoxville, Tennessee
which it primarily uses for project engineering, project management and
accounting offices and a 12-month lease for an approximately 10,000 square foot
assembly facility.

          In addition to the two primary facilities above, the Company leases a
sales office in Houston, Texas and an office in Rockville, Maryland under month-
to-month leases.  The Company leases approximately 1,000 square feet of office
space in London, England under a five-year lease, which it uses for sales and a
5,000 square foot office in Hessle, England under a six year lease which it uses
for operations and engineering.  The Company anticipates subletting the London
office in 1997 and housing all European activities in the Hessle office space
thereafter.

ITEM 3.    LEGAL PROCEEDINGS

          The Company is involved in various routine legal proceedings incident
to the ordinary course of its business.  Management believes that the outcome of
all pending legal proceedings in the aggregate will not have a material effect
on the Company's business, financial condition or result of operations.


ITEM 4.    SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

          No matters were submitted to a vote of stockholders during the fourth
quarter of the Company's fiscal year.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

GENERAL

          Thermatrix Inc. is a global industrial technology company primarily
engaged in the development, manufacture and sale of industrial process equipment
for the destruction of volatile organic compounds and hazardous air pollutants
(collectively, "VOCs"). The core component of the Company's technology is its
proprietary flameless thermal oxidizer ("FTO").

          The Company derives its revenues primarily from contracts to develop
and manufacture FTO systems for the treatment of VOCs. In general, the Company
pursues new market applications to control industrial VOC emissions by
collaborating with a strategic customer in the particular market area. Under
these collaborative arrangements, the customer's engineers and other technical
personnel work closely with the Company to design and develop an industry- and
application-specific system. The Company prices these initial installations at
or near the Company's estimated cost.  Such applications development projects
generate little or no gross margins. This allows the Company to recover the
costs of its application development efforts while establishing the acceptance
of the Company's technology with market leader customers. The Company believes
these collaborative efforts will continue to be important to its success, and
the Company intends to continue to develop applications for its technology
utilizing these collaborative relationships in the future. Systems for
established applications are priced higher, can generally be produced at lower
cost and have higher gross margins. The Company principally uses the percentage-
of-completion method of accounting to recognize contract revenues. Losses on
contracts are charged to cost of revenues as soon as such losses become known.

          The Company's core technology has been successfully commercialized in
the industrial VOC control market for applications in the petroleum,
chemical/petrochemical, pharmaceutical, medical sterilization and pulp and paper
industries, and for soil and groundwater remediation. The Company will seek to
expand into additional segments of the industrial VOC control market. Because
the Company's technology has been commercialized, the Company does not expect
that costs associated with further research and development of its core FTO
technology for the industrial VOC control market will be material to the
Company's results of operations.

          In addition to its current market for industrial VOC emission
controls, the Company is currently working with strategic partners to evaluate
the feasibility of applying the Company's technology to other markets.  In
October 1996, the Company entered into a joint venture (Formatrix, LLC) with
ThermoChem, Inc. to explore the commercialization of a system to treat mixed
wastes.  Also, the Company is completing tests to address the feasibility of the
Company's system to treat emissions from diesel engines. The strategic partners
generally share some, but not all, of the evaluation costs. Expenses incurred by
the Company, primarily labor costs, are generally recorded as research and
development expenses. To the extent such research and development expenses are
reimbursed by the strategic partner, these amounts are reflected as a reduction
of research and development expenses. If evaluation costs are reimbursed under
the terms of a purchase contract, these amounts are reflected as cost of
revenues. In addition, the Company, in some cases, may provide an evaluation
system to the strategic partner. Such costs are capitalized and amortized over
the estimated useful life of the evaluation system. Currently, expenses incurred
by the Company for these recent development programs have not been material.
However, if the early tests in any of these new applications are positive, the
Company may need to engage in more extensive development and engineering in
order to commercialize its technology for such use. There can be no assurance as
to the outcome of such evaluation programs or, if initiated, the outcome of any
such applications development and engineering effort.

          The Company's quarterly revenues and operating results have varied
significantly in the past and may fluctuate significantly in the future as a
result of a variety of factors, many of which are outside the Company's control.
Such factors include general economic and industry conditions, the size and
timing of individual orders, the timing and amount of project change orders, the
amount of first-time engineering needed, the introduction of new products or
services by the Company or its competitors or the introduction of the Company's
products to new markets, changes in the levels of operating expenses, including
development costs, and the amount and timing of other costs relating to the
expansion of the Company's operations.

                                       18
<PAGE>
 
          Furthermore, the purchase of the Company's products, particularly for
major projects, may involve a significant commitment of capital, with the
attendant delays frequently associated with large capital expenditures and
authorization procedures within its customers' organization.  For these and
other reasons, the sales cycle for the Company's products can be lengthy (up to
two years) and subject to a number of significant risks over which the Company
has little or no control, including customer budgetary constraints.  The Company
historically has operated with little backlog because most customer orders are
placed with relatively short lead times, usually from four to twenty-four weeks.
Variations in the timing of recognition of specific revenues due to changes in
project scope and timing may adversely and disproportionately affect the
Company's operating results for a quarter because the Company establishes its
expenditure levels on the basis of expected future revenues, and a significant
portion of the Company's expenses do not vary with current revenues.

          Although the Company is expanding the number of its customers and
installations, the average size and dollar volume of each installation is
increasing.  As a result, the Company's results of operations are likely to
continue to be dependent on major projects.  Such a reliance on major orders is
likely to lead to fluctuations in, and to reduce the predictability of,
quarterly results.  Larger projects also pose other challenges.  The sales cycle
for larger projects tends to be longer than for smaller projects, and, when
orders are received, projects may be delayed by factors outside the Company's
control, including customer budget decisions, design changes and delays in
obtaining permits.  Also, because the dollar volumes are larger, the costs of
providing warranty services could increase.  The Company's business, results of
operations and financial condition could be materially adversely affected if the
Company were to fail to obtain major project orders, if such orders were
delayed, if installations of such systems were delayed, or if such installations
encountered operating, warranty or other problems.

          In April 1996, the Company acquired from Purus, Inc. its PADRE
technology, which is a process used to capture and recover very low
concentration VOCs from low to medium flow vapor streams. The PADRE technology
was acquired from Purus, Inc. as a fully developed technology and commercial
units of the PADRE system have been sold. Therefore, the Company does not expect
to incur material research and development costs in connection with the
manufacture and sale of stand-alone PADRE units. Sales of PADRE units are
subject to a 7% royalty payable to Purus, Inc.


RESULTS OF OPERATIONS

          Fiscal years Ended December 31, 1996, 1995 and 1994
          ---------------------------------------------------

          Revenues increased 110% to $13.6 million in 1996 from $6.5 million in
1995.  The increase in revenues is primarily attributable to an increased
acceptance of the Company's technology which included contracts for systems used
in chemical/petrochemical, petroleum, and pulp and paper industry applications,
orders for systems used in remediation projects, and the first unit for use in
medical sterilization.  Revenues in 1996 also reflected the Company's first
sales of PADRE units, the technology acquired from Purus, Inc. in April 1996.
Three customers accounted for 13%, 13% and 12% of revenues, respectively, as the
Company's customer base increased and the Company's dependence on specific major
customers decreased.  In 1996, sales to international customers increased to 14%
with orders in Europe and in Asia. Revenues grew 107% to $6.5 million in 1995,
from $3.1 million in 1994, with two customers accounting for 41% and 18% of
revenues. The increase in revenues from 1994 to 1995 represented follow-on sales
in the petroleum and chemical/petrochemical industries and for soil and
groundwater remediation as well as systems installed in new industrial
applications involving the treatment of sulfonated and fluorinated compounds and
PCB contaminated soil.

          Gross profit as a percentage of revenues for 1996, 1995 and 1994 was
11.8%, 6.6% and 1.1%, respectively.  The increase in gross profit is
attributable in part to an increase in follow-on sales for existing
applications, increased pricing as the Company begins to value price its systems
and, to a lesser extent, reductions in costs from repeat sales of systems for
established applications.  Gross profit margins are affected by numerous factors
including growth of the operations infrastructure, international expansion,
initial systems addressing new industries or new applications, larger, more
complex systems and the extent and timing of change orders.  The growth in the
Company's business has necessitated hiring additional design engineers,
instrumentation and control engineers and project management personnel.
Significant training and familiarization with the Company's FTO 

                                       19
<PAGE>
 
technology results in these new individuals not being fully engaged in revenue
producing activities which reduces gross profit percentages. As the Company
grows internationally, operations infrastructure needs to be added to support
the sales activities. In 1997, the Company will add an applications engineer in
Asia and will add project management support on assignment from the U.S.
operations. In Europe, the Company is recruiting project management and
engineering capabilities and has added a senior operations director. In
addition, the European operations are being supported by people on assignment
from the U.S. Engineering costs and gross margins are impacted by first-time
shipments to a foreign country as the Company must comply with the different
construction and regulatory codes of that country location. New industry and/or
fume characteristics require the Company to expend significantly greater
engineering resources in process design and system design. Also such new
applications are usually sold at lower initial gross margins as the customer and
Company make investments in the development effort. As systems get larger and
more complex with hybrid technologies and purchased components, overall gross
margin percentages are affected by the Company's ability to mark up the
purchased components in the final system. Project change orders can be nominal
or can be significant. The Company does not recognize change orders as revenue
until the change order is accepted by the customer or acceptance is probable.
Depending upon the magnitude of the change order, gross margins can also be
affected.

          Research and development expenses include applications engineering
expenses not chargeable to specific customer projects, as well as the cost of
patent activities.  Research and development expenses during 1996, 1995 and 1994
were $748,000, $1.1 million and $1.3 million, respectively.  The reduction in
research and development expenses primarily reflects the Company's success in
developing collaborative efforts with its industrial customers, thereby reducing
its own independent expenditures for applications development.

          The Company's sales cycle is affected by numerous conditions outside
of the Company's control and can extend up to two years.  The Company therefore
incurs sales and marketing costs well in advance of the receipt of orders.
Bookings of new orders are not consistent from month to month or from quarter to
quarter, which can have a material effect on the Company's quarterly revenues.
In addition, the booking of any large order in any quarter can have a material
effect on the revenue for a subsequent quarter or quarters as revenue generated
on large orders is typically recognized over six to seven months. Based on the
Company's current level of revenues these larger orders have a more significant
impact. Orders are often booked in phases and initial phases may be performed
but the subsequent phases may be delayed or canceled. These factors can lead to
unusual quarterly fluctuations in revenue, gross margins and net income.
Selling, general and administrative expenses increased to $6.2 million in 1996
as compared to $4.7 million in 1995 and $4.5 million in 1994, primarily as a
result of increased sales commissions, proposal activity, liability insurance
and other costs related to the increased level of sales. Also, the second half
of 1996 reflected the increased costs of complying with the additional reporting
requirements and other costs of a public company. The Company anticipates that
these costs will increase in 1997 as a result of being a public company for a
full year. As a percentage of revenues, selling, general and administrative
expenses decreased to 45.3% in 1996 as compared to 73.0% in 1995 and 143.6% in
1994.

          Interest income of $548,000 in 1996 primarily results from the
investment of the net proceeds from the Company's initial public offering
completed in June 1996.  Interest income of $231,000 in 1995 resulted from the
investment of the net proceeds of an equity private placement in November 1994.


LIQUIDITY AND CAPITAL RESOURCES

          In February 1996, the Company sold 284,594 shares of its Series D
Preferred Stock at $7.50 per share to existing investors for net cash of $2.1
million.  In June 1996, the Company completed its initial public offering
raising net proceeds of $22.1 million.

          During 1996, 1995 and 1994, the Company used $7.9 million, $5.5
million and $5.8 million, respectively, in operating activities and $1.2
million, $528,000 and $319,000, respectively, in investing activities primarily
for capital equipment and patent and other asset expenditures. The Company
anticipates it will continue to incur losses and will require increased levels
of working capital to finance any future growth.  Total cash and short-term
investments were $16.2 million at December 31, 1996.  The Company has a $4.0
million bank line of credit which expires February 25, 1998.  There are no
borrowings outstanding under the line of credit as of February 28, 1997.  The
Company believes that its current cash and short-term investments, together with
the availability of its line of credit, will be sufficient to finance its
working capital and other capital requirements through 1997.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To Thermatrix Inc.:

          We have audited the accompanying consolidated balance sheets of
Thermatrix Inc. (a Delaware corporation) and subsidiary as of December 31, 1996
and 1995, and the related consolidated statements of operations, stockholders'
equity (deficit) and cash flows for each of the three years in the period ended
December 31, 1996. These financial statements and the schedule referred to below
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements and schedule 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 Thermatrix Inc. and
subsidiary as of December 31, 1996 and 1995, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1996 in conformity with generally accepted accounting principles.

          Our audits were made for the purpose of forming an opinion on the
basic consolidated financial statements taken as a whole.  The schedule listed
under Item 14 is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not a required part of the basic consolidated
financial statements. This schedule has been subjected to the auditing
procedures applied in the audit of the basic consolidated financial statements
and, in our opinion, fairly states in all material respects the financial data
required to be set forth in relation to the basic consolidated financial
statements taken as a whole.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.        ORGANIZATION AND OPERATIONS OF THE COMPANY

          Thermatrix Inc. (the "Company") is a global industrial technology
company primarily engaged in the development, manufacture and sale of industrial
process equipment for the destruction of volatile organic compounds and
hazardous air pollutants (collectively, "VOCs"). The Company markets its
products to a wide variety of industries, including petroleum,
chemical/petrochemical, pharmaceutical, pulp and paper, and medical
sterilization and for soil and groundwater remediation, throughout the world.

          In June 1996, the Company completed an initial public offering of
2,000,000 shares of common stock at $12.50 per share.  Total proceeds to the
Company, net of underwriting discounts and other direct expenses, were
approximately $22.1 million.

          The Company is subject to certain risks that include, but are not
limited to, the following:  history of operating losses and uncertainty of
future profitability; sensitivity to major projects and fixed price contracts.
At December 31, 1996, the Company had an accumulated deficit of approximately
$27.1 million and expects to incur additional losses in the future. The Company
does not expect to be profitable unless and until such time as sales of
flameless thermal oxidation systems generate sufficient revenue to fund its
operations. There can be no assurance that the Company will achieve such
revenues. The Company's operating results are sensitive to major projects such
that results of operations and financial condition could be adversely affected
if the Company failed to obtain major projects, if a major project order was
delayed, if the Company was unable to complete the project within its cost
estimate or if such installations encountered operating or warranty problems.


2.        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

          Use of Estimates
          ----------------

          The preparation 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 period.
The Company prepares and evaluates ongoing cost to complete estimates in order
to monitor its project costs. These estimates form the basis for calculating
revenues and gross margins for each project under the percentage-of-completion
method of accounting. Due to uncertainties inherent in the estimation process,
estimated total costs are subject to revision on an on-going basis as additional
information becomes available. The estimates are subject to change and actual
results could be materially different from these estimates.

          Principles of Consolidation and Foreign Currency Translation
          ------------------------------------------------------------

          The consolidated financial statements include the accounts of the
Company and its wholly owned subsidiary. The functional currency of the
subsidiary is the U.S. dollar. Accordingly, all translation gains and losses
resulting from transactions denominated in currencies other than the U.S. dollar
are included in the statement of operations. To date, the translation gains and
losses have not been material. All intercompany accounts and transactions have
been eliminated.

          Joint Venture
          -------------
       
In October 1996, the Company entered into an agreement with ThermoChem, Inc. to
establish a joint venture, Formatrix, LLC, to combine, under license, the
patented technologies of the joint venture partners.  The Company owns 40% of
Formatrix, LLC and, as of December 31, 1996, the carrying amount of the
investment in

                                THERMATRIX INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)


Formatrix, LLC  was  $252,000.  Formatrix, LLC had no operations in the period
from its inception to December 31, 1996.  The Company's investment in Formatrix,
LLC is accounted for under the equity method.

          Cash and Cash Equivalents
          -------------------------

          For purposes of the statements of cash flows, the Company considers
all short-term investments purchased with a maturity of three months or less to
be cash equivalents.

Short-term Investments
- ----------------------

          Under  Statement of Financial Accounting Standards ("SFAS") No. 115,
"Accounting for Certain Investments in Debt and Equity Securities" the Company
classifies its short-term investments as "held to maturity."  Therefore all of
these investments are carried at amortized cost.  Unrealized holding gains or
losses as of December 31, 1996 were not material.  As of December 31, 1996,
short-term investments mature at various dates through December 1997.

          At December 31, 1996 the amortized cost, aggregate fair value and
gross unrealized holding gains (losses) by major security type are as follows
(in thousands):
 
                                         Amortized   Aggregate      Unrealized
                                           Cost      Fair Value   Gains (Losses)
                                         ---------   ----------   --------------
 
            Certificates of deposit        $ 2,022      $ 2,022       $  -
            Corporate debt securities        8,247        8,251          4
            Money market instruments         1,149        1,149          -
                                           -------      -------       ----
 
                                             $11,418      $11,422     $  4
                                             =======      =======     ====


As of December 31, 1994, investments, which consisted entirely of commercial
paper, were classified as "available for sale."  These investments, which
matured in September 1995, were valued at market value as of December 31, 1994.
The gross unrealized holding loss at December 31, 1994 was not material.

          Revenue Recognition
          -------------------

          The Company principally uses the percentage-of-completion method of
accounting for contract revenues. The percentage-of-completion method is based
on total costs incurred to date compared with estimated total costs upon
completion of contracts. The completed contract method of accounting is used for
certain contracts when the Company does not have sufficient historical data to
enable it to prepare dependable cost estimates. Losses on contracts are charged
to cost of revenues as soon as such losses become known. Due to uncertainties
inherent in the estimation process, estimated total costs are subject to
revision on an ongoing basis as additional information becomes available. The
Company recognizes revenue and costs attributable to priced and unpriced change
orders when it is probable that the contract price will be adjusted and the
amount of the change order can be reliably estimated. The Company warrants only
new systems manufactured by the Company for defective workmanship and/or
materials for a period of 12 months from initial operation of the system or 18
months after shipment or notification that the system is ready for shipment,
whichever occurs first. A provision for estimated warranty costs is provided for
each unit produced by the Company.

          The unbilled amounts represent revenues recognized under the
percentage-of-completion method of accounting which exceed the amounts that are
billable according to contract terms. The unbilled amounts are generally
billable as contract milestones and deliverables are accepted by the customer or
as change orders are submitted and approved. As of December 31, 1996 and 1995,
accounts receivable included approximately $793,000 and $1,129,000,
respectively, of unpriced change orders.

          As of December 31, 1996, 61% of accounts receivable was concentrated
with five customers.  As of December 31, 1995, approximately 75% of accounts
receivable was concentrated with two customers.

          Concentration of Credit Risk
          ----------------------------

          Financial instruments that potentially subject the Company to
concentrations of credit risk consist principally of short-term cash investments
and accounts receivable. The Company has cash investment policies that limit its
investments to short-term, low risk investments. With respect to accounts
receivable, the Company performs ongoing credit evaluations of its customers'
financial condition. Additionally, the Company establishes an allowance for
doubtful accounts based upon factors surrounding the credit risk of specific
customers, historical trends and other information.

          Property and Equipment
          ----------------------

          Property and equipment are stated at cost. Depreciation is provided
using the straight-line method over the estimated lives of the assets of three
to five years. Leasehold improvements are amortized over the shorter of the
related lease term or the estimated useful life of the asset. Betterments,
renewals and extraordinary repairs that extend the life of the asset are
capitalized; other repairs and maintenance are expensed.

          As required by SFAS No. 121, "Accounting for the Impairment of Long-
Lived Assets and for Long-Lived Assets to be Disposed Of," the Company regularly
evaluates the remaining life and recoverability of its equipment. The Company
adopted the provisions of this statement in 1995. The adoption did not have a
significant effect on the Company's financial position and results of
operations. Given the emerging nature of its markets, it is possible that the
Company's estimate that it will recover the net carrying value of the equipment
from future operations could change in the future.

Patent Costs
- ------------

          Direct costs incurred in connection with the filing of the Company's
patent claims are capitalized as patent costs. Such amounts are amortized over
the estimated economic useful lives of the patents (generally ten years).

            Significant Customers
            ---------------------

          Revenues from government contracts as a percentage of total revenues
was 15%, 19% and 0% for the years ended December 31, 1996, 1995 and 1994,
respectively.  The principal government agencies to which the Company sells are
the Department of Defense and the Department of Energy.  To date, the Company's
revenues have been derived predominantly from customers located in the United
States.  Revenues from international customers as a percentage of total revenues
were 14% for the year ended December 31, 1996 and less than 10% for each of the
years ended December 31, 1995 and 1994.

          Net Loss Per Share and Pro Forma Net Loss Per Share
          ---------------------------------------------------

          Net loss per share is computed using the weighted average number of
common and common equivalent shares outstanding during the period.  Common
equivalent shares have been excluded from the computation as their effect is
antidilutive.

          Pro forma net loss per share was computed using the weighted average
number of common and common equivalent shares outstanding during the period.
Common  equivalent shares consisted of redeemable convertible preferred stock
and convertible preferred stock (using the if converted method) and stock
options and warrants (using the treasury stock method).  Common equivalent
shares were excluded from the computation if their effect was antidilutive
except that pursuant to the Securities and Exchange Commission Staff Accounting
Bulletin No. 83, such computations include all common and common equivalent
shares issued within the 12 months preceding the filing date of the Company's
Registration Statement as if they were outstanding for all periods presented
(using the treasury stock method and an initial public offering price of $12.50
per share).  Redeemable convertible preferred stock and convertible preferred
stock outstanding during the period are included (using the if converted method)
in the computation as common equivalent shares even though the effect is
antidilutive. Historical earnings per share prior to 1995 have not been
presented since such amounts are not deemed meaningful due to the significant
change in the Company's capital structure resulting from its initial public
offering.

adopted new stock plans (see below); accordingly, the Company does not plan to
issue further options to purchase common stock under the Plan.

          1996 Stock Plan ("1996 Plan")
          ----------------------------

          A total of 333,334 shares of common stock has been reserved for
issuance under the 1996 Plan. The 1996 Plan provides that options and stock
purchase rights may be granted to employees and consultants to the Company.
Options granted under the 1996 Plan may be either incentive stock options or
nonstatutory stock options. The Company may also grant stock purchase rights
under the 1996 Plan. The exercise price and vesting of all grants are to be
determined by the Board of Directors or its designee. Options granted under the
1996 Plan expire 10 years from the date of grant. The 1996 Plan will terminate
in 2006.

          1996 Director Option Plan ("Directors Plan")
          -------------------------------------------

          A total of 83,334 shares of common stock has been reserved for
issuance under the Directors Plan.   The Directors Plan provides for an
automatic grant to each director of an initial option to purchase 6,667 shares
of common stock ("First Option") upon the date on which such person becomes a
non-employee director, and an additional option to purchase 1,667 shares of
common stock ("Subsequent Option") each year, if the director has served on the
Company's Board of Directors for at least six months. Options granted under the
Directors Plan expire ten years after the date of grant. Twelve and one-half
percent of the shares subject to a First Option will vest six months after its
date of grant and an additional twelve and one-half percent will vest at the end
of each six-month period thereafter. One-half of the shares subject to a
Subsequent Option will vest six months after the date of the option grant and as
to the remaining one-half, one year after the date of grant. The exercise price
per share of all options shall be equal to the fair market value of the
Company's common stock on the date of grant. The Directors Plan will terminate
in 2006.

Employee Stock Purchase Plan ("Purchase Plan")
- ---------------------------------------------

          A total of 116,667 shares of common stock are reserved for issuance
under the Purchase Plan. The Purchase Plan enables eligible employees to
purchase common stock at the lower of 85% of the fair market value of the
Company's common stock on the first or last day of each six-month offering
period. The first offering period, however, began on June 19, 1996 and will end
on the last market trading day on or before April 30, 1997. The Purchase Plan
will terminate in 2006.

          The Company applies Accounting Principles Board Opinion No. 25.
"Accounting for Stock Issued to Employees" and related interpretations in
accounting for its plans.  Accordingly, no compensation cost has been recognized
for its stock plans.  Had compensation cost for the Company's plans been
determined based on the fair value at the grant dates for awards under the plans
consistent with the method of SFAS No. 123, "Accounting for Stock-Based
Compensation", the Company's net loss and net loss per share would have been
changed to the pro forma amounts indicated below (in thousands):
 
                                                           1996        1995

                       Pro forma.......................      (0.76)      (0.91)


          For the purpose of SFAS No. 123, the fair value of each option grant
is estimated on the date of grant using the Black-Scholes multiple option-
pricing model with the following weighted-average assumptions used for grants in
1995 and 1996 respectively:  dividend yield of 0% for all grants; expected
volatility of 0 prior to initial public offering and 85 percent thereafter;
risk-free interest rates ranging from 5.20 to 6.80 percent; and expected lives
of one to two years for each grant.

8.        INCOME TAXES

          The Company has adopted a liability approach to income taxes under
which deferred income taxes are provided based upon enacted tax laws and rates
applicable to the periods in which the taxes become payable.

          The provision for income taxes differs from the statutory U.S. Federal
income tax rate due to the following:
 
                                                         FOR THE YEARS

          The provision for income taxes for the years ended December 31, 1996
and 1995 relates to state taxes against which no net operating loss can be
applied.

          The net deferred income tax asset consisted of the following (in
thousands):
 
                                                             DECEMBER 31,

          Deferred income tax assets:

               Tax credit carryforwards...............    193             83

          Net deferred income tax asset............... $   --         $   --
                                                       ======         ======

          As of December 31, 1996, the Company had net operating loss
carryforwards for Federal and state income tax purposes of approximately $25.8
million and $13.0 million, respectively. The net operating loss carryforwards
and tax credit carryforwards expire on various dates through 2011.  The Internal
Revenue Service Code contains provisions which may limit the net operating loss
and tax credit carryforwards to be used in any given year upon the occurrence of
certain events.  Certain of the Company's net operating loss and tax credit
carryforwards are limited due to an ownership change.  Cumulative temporary
differences consist of reserves and accruals currently deductible for financial
reporting purposes, but not for tax purposes. The Company believes sufficient
uncertainty exists regarding the realizability of the operating loss and credit
carryforwards and, accordingly, has continued to provide a valuation allowance
against the deferred income tax asset.

9.        LOAN AND SECURITY AGREEMENT

          In December 1995, the Company entered into a Loan and Security
Agreement ("Agreement") with a bank which provided for a $3,000,000 bridge loan,
available in two equal parts of $1,500,000, and bore interest at the bank's
prime interest rate plus 2.5%.  The Agreement was extended past its original
expiration date while new terms and conditions were negotiated.  No amounts were
outstanding under the Agreement as of December 31, 1996 and 1995.

          In consideration for the Agreement, the Company granted the bank a
warrant to purchase 28,571 shares of Series D redeemable convertible preferred
stock at $5.25 per share (as adjusted).  The fair value of the warrants at the
date of issuance was not significant and, therefore, no value was assigned to
the warrants for accounting purposes.  Subsequent to the Company's initial
public offering, these warrants were convertible into warrants to purchase
common stock.

          In February 1997, the Company entered into an Amended and Restated
Loan and Security Agreement (the "New Agreement") which provides for a
$4,000,000 committed line of credit and a $2,500,000 acquisition facility.  The
committed line will bear interest at the prime interest rate plus 0.50% and will
be subject to certain financial and nonfinancial covenants.  Any borrowings
under the acquisition facility will bear interest at the prime interest rate
plus 1.00%.  The New Agreement expires on February 25, 1998.

account of Borrower in an aggregate face amount not to exceed the lesser of the

which delivery is to be effected or settlement allowed within two business days
after the Determination Date, 100% of the gross amount of the Exchange
Contracts. In lieu of the Foreign Exchange Reserve for 100% of the gross amount

        9.      BANK'S RIGHTS AND REMEDIES
                --------------------------

                9.1     Rights and Remedies. Upon the occurrence and during the
                        -------------------
continuance of an Event of Default, Bank may, at its election, without notice of
its election and without demand, do any one or more of the following, all of
which are authorized by Borrower:

                        (a)  Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the 

                                      18
<PAGE>
 
occurrence of an Event of Default described in Section 8.5 all Obligations shall
become immediately due and payable without any action by Bank);

                        (b)  Cease advancing money or extending credit to or for
the benefit of Borrower under this Agreement or under any other agreement
between Borrower and Bank;

                        (c)  Demand that Borrower (i) deposit cash with Bank in
an amount equal to the amount of any Letters of Credit remaining undrawn, as
collateral security for the repayment of any future drawings under such Letters
of Credit, and Borrower shall forthwith deposit and pay such amounts, and (ii)
pay in advance all Letters of Credit fees scheduled to be paid or payable over
the remaining term of the Letters of Credit;

                        (d)  Settle or adjust disputes and claims directly with
account debtors for amounts, upon terms and in whatever order that Bank
reasonably considers advisable;

                        (e)  Without notice to or demand upon Borrower, make
such payments and do such acts as Bank considers necessary or reasonable to
protect its security interest in the Collateral. Borrower agrees to assemble the
Collateral if Bank so requires, and to make the Collateral available to Bank as
Bank may designate. Borrower authorizes Bank to enter the premises where the
Collateral is located, to take and maintain possession of the Collateral, or any
part of it, and to pay, purchase, contest, or compromise any encumbrance,
charge, or lien which in Bank's determination appears to be prior or superior to
its security interest and to pay all expenses incurred in connection therewith.
With respect to any of Borrower's owned premises, Borrower hereby grants Bank a
license to enter into possession of such premises and to occupy the same,
without charge, for up to one hundred twenty (120) days in order to exercise any
of Bank's rights or remedies provided herein, at law, in equity, or otherwise;

                        (f)  Without notice to Borrower set off and apply to the
Obligations any and all (i) balances and deposits of Borrower held by Bank, or
(ii) indebtedness at any time owing to or for the credit or the account of
Borrower held by Bank;

                        (g)  Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner provided
for herein) the Collateral. Bank is hereby granted a license or other right,
solely pursuant to the provisions of this Section 9.1, to use, without charge,
Borrower's labels, patents, copyrights, rights of use of any name, trade
secrets, trade names, trademarks, service marks, and advertising matter, or any
property of a similar nature, as it pertains to the Collateral, in completing
production of, advertising for sale, and selling any Collateral and, in
connection with Bank's exercise of its rights under this Section 9.1, Borrower's
rights under all licenses and all franchise agreements shall inure to Bank's
benefit;

                        (h)  Sell the Collateral at either a public or private
sale, or both, by way of one or more contracts or transactions, for cash or on
terms, in such manner and at such places (including Borrower's premises) as Bank
determines is commercially reasonable, and apply any proceeds to the Obligations
in whatever manner or order Bank deems appropriate;

                        (i)  Bank may credit bid and purchase at any public
sale; and

                        (j)  Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

                9.2     Power of Attorney. Borrower hereby irrevocably appoints
                        -----------------
Bank (and any of Bank's designated officers, or employees) as Borrower's true
and lawful attorney to: (a) send requests for verification of Accounts or notify
account debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into 

                                      19
<PAGE>
 
Bank's possession; (c) sign Borrower's name on any invoice or bill of lading
relating to any Account, drafts against account debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (d) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; and (e) settle and adjust disputes
and claims respecting the accounts directly with account debtors, for amounts
and upon terms which Bank determines to be reasonable; provided Bank may
exercise such power of attorney to sign the name of Borrower on any of the
documents described in Section 4.2 regardless of whether an Event of Default has
occurred. The appointment of Bank as Borrower's attorney in fact, and each and
every one of Bank's rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid and performed
and Bank's obligation to provide advances hereunder is terminated.

                9.3     Accounts Collection. At any time from the date of this
                        -------------------
Agreement, Bank may notify any Person owing funds to Borrower of Bank's security
interest in such funds and verify the amount of such Account. Borrower shall
collect all amounts owing to Borrower for Bank, receive in trust all payments as
Bank's trustee, and immediately deliver such payments to Bank in their original
form as received from the account debtor, with proper endorsements for deposit.

                9.4     Bank Expenses. If Borrower fails to pay any amounts or
                        -------------
furnish any required proof of payment due to third persons or entities, as
required under the terms of this Agreement, then Bank may do any or all of the
following: (a) make payment of the same or any part thereof; (b) set up such
reserves under the Revolving Facility as Bank deems necessary to protect Bank
from the exposure created by such failure; or (c) obtain and maintain insurance
policies of the type discussed in Section 6.6 of this Agreement, and take any
action with respect to such policies as Bank deems prudent. Any amounts so paid
or deposited by Bank shall constitute Bank Expenses, shall be immediately due
and payable, and shall bear interest at the then applicable rate hereinabove
provided, and shall be secured by the Collateral. Any payments made by Bank
shall not constitute an agreement by Bank to make similar payments in the future
or a waiver by Bank of any Event of Default under this Agreement.

                9.5     Bank's Liability for Collateral. Bank shall not in any
                        -------------------------------
way or manner be liable or responsible for: (a) the safekeeping of the
Collateral; (b) any loss or damage thereto occurring or arising in any manner or
fashion from any cause; (c) any diminution in the value thereof; or (d) any act
or default of any carrier, warehouseman, bailee, forwarding agency, or other
person whomsoever. All risk of loss, damage or destruction of the Collateral
shall be borne by Borrower.

                9.6     Remedies Cumulative. Bank's rights and remedies under
                        -------------------
this Agreement, the Loan Documents, and all other agreements shall be
cumulative. Bank shall have all other rights and remedies not inconsistent
herewith as provided under the Code, by law, or in equity. No exercise by Bank
of one right or remedy shall be deemed an election, and no waiver by Bank of any
Event of Default on Borrower's part shall be deemed a continuing waiver. No
delay by Bank shall constitute a waiver, election, or acquiescence by it. No
waiver by Bank shall be effective unless made in a written document signed on
behalf of Bank and then shall be effective only in the specific instance and for
the specific purpose for which it was given.

                9.7     Demand; Protest. Borrower waives demand, protest, notice
                        ---------------
of protest, notice of default or dishonor, notice of payment and nonpayment,
notice of any default, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which Borrower may in any way be liable.

        10.     NOTICES

                12.1    Successors and Assigns. This Agreement shall bind and
                        ----------------------
inure to the benefit of the respective successors and permitted assigns of each
of the parties; provided, however, that neither this Agreement nor any rights
                -----------------
hereunder may be assigned by Borrower without Bank's prior written consent,
which consent may be granted or withheld in Bank's sole discretion. Bank shall

                12.5    Amendments in Writing Integration. This Agreement amends
                        ---------------------------------
and restates the terms of a Loan and Security Agreement existing on the Closing
Date between Borrower and Bank. The security interest granted under the terms of
that agreement continues to secure the Obligations, as defined herein, and the

                        --------
made in this Agreement shall continue in full force and effect so long as any

with respect to the expenses, damages, losses, costs and liabilities described

                12.8    Confidentiality. In handling any confidential
                        ---------------
information Bank shall exercise the same degree of care that it exercises with
respect to its own proprietary information of the same types to maintain the
confidentiality of any non-public information thereby received or received
pursuant to this Agreement except that disclosure of such information may be
made (i) to the subsidiaries or affiliates of Bank in connection with their
present or prospective business relations with Borrower, (ii) to prospective
transferees or purchasers of any interest in the Loans, provided that they have
entered into a comparable confidentiality agreement in favor of Borrower and
have delivered a copy to Borrower, (iii) as required by law, regulations, rule
or order, subpoena, judicial order or similar order, (iv) as may be required in
connection with the examination, audit or similar investigation of Bank and (v)
as Bank may determine in connection with the enforcement of any remedies

ASSIGNOR'S OBLIGATIONS TO ASSIGNEE UNDER THE LOAN AGREEMENT.

        2.   Authorization and Request. Assignor authorizes and requests that
             -------------------------
the Register of Copyrights and the Commissioner of Patents and Trademarks record

        3.   Covenants and Warranties. Assignor represents, warrants, covenants
             ------------------------
and agrees as follows:

             (a)  Assignor is now the sole owner of the Collateral, except for
non-exclusive licenses granted by Assignor to its customers in the ordinary
course of business;

             (b)  Performance of this Assignment does not conflict with or
result in a breach of any agreement to which Assignor is party or by which
Assignor is bound, except to the extent that certain intellectual property
agreements prohibit the assignment of the rights thereunder to a third party
without the licensor's or other party's consent and this Assignment constitutes
an assignment;

             (c)  During the term 6f this Assignment, Assignor will not transfer
or otherwise encumber any interest in the Collateral, except for non-exclusive
licenses granted by Assignor in the ordinary course of business or as set forth
in this Assignment;

             (d)  To its knowledge, each of the Patents is valid and
enforceable, and no part of the Collateral has been judged invalid or
unenforceable, in whole or in part, and no claim has been made that any part of
the Collateral violates the rights of any third party;

             (e)  Assignor shall promptly advise Assignee of any material change
in the composition of the Collateral, including but not limited to any
subsequent ownership right of the Assignor in. or to any Trademark, Patent or
Copyright not specified in this Assignment;

             (f)  Assignor shall (i) protect, defend and maintain the validity
and enforceability of the Trademarks, Patents and Copyrights, (ii) use its best
efforts to detect infringements of the Trademarks, Patents and Copyrights and
promptly advise Assignee in writing of material infringements detected and (iii)
not allow any Trademarks, Patents or Copyrights to be abandoned, forfeited or
dedicated to the public without the written consent of Assignee, which shall not
be unreasonably withheld, unless Assignor determines that reasonable business
practices suggest that abandonment is appropriate.

             (g)  Assignor shall promptly register the most recent version of
any of Assignor's Copyrights, if not so already registered, and shall, from time
to time, execute and file such other instruments, and take such further actions
as Assignee may reasonably request from time to time to perfect or continue the
perfection of Assignee's interest in the Collateral;

                                       2
<PAGE>
 
             (h)  This Assignment creates, and in the case of after acquired
Collateral, this Assignment will create at the time Assignor first has rights in
such alter acquired Collateral, in favor of Assignee a valid and perfected first
priority security interest in the Collateral in the United States securing the
payment and performance of the obligations evidenced by the Note upon making the
filings referred to in clause (i) below;

             (i)  To its knowledge, except for, and upon, the filing with the
United States Patent and Trademark office with respect to the Patents and
Trademarks and the Register of Copyrights with respect to the Copyrights
necessary to perfect the security interests and assignment created hereunder,
and except as has been already made or obtained, no authorization, approval or
other action by, and no notice to or filing with, any US. governmental authority
or US. regulatory body is required either (i) for the grant by Assignor of the
security interest granted hereby or for the execution, delivery or performance
of this Assignment by Assignor in the US. or (ii) for the perfection in the
United States or the exercise by Assignee of its rights and remedies hereunder;

             (j)  All information heretofore, herein or hereafter supplied to
Assignee by or on behalf of Assignor with respect to the Collateral is accurate
and complete in all material respects.

             (k)  Assignor shall not enter into any agreement that would
materially impair or conflict with Assignor's obligations hereunder without
Assignee's prior written consent, which consent shall not be unreasonably
withheld. Assignor shall not permit the inclusion in any material contract to
which it becomes a party of any provisions that could or might in any way
prevent the creation of a security interest in Assignor's rights and interests
in any property included within the definition of the Collateral acquired under
such contracts, except that certain contracts may contain anti-assignment
provisions that could in effect prohibit the creation of a security interest in
such contracts.

             (1)  Upon any executive officer of Assignor obtaining actual
knowledge thereof, Assignor will promptly notify Assignee in writing of any
event that materially adversely affects the value of any Collateral, the ability
of Assignor to dispose of any Collateral or the rights and remedies of Assignee
in relation thereto, including the levy of any legal process against any of the
Collateral.

        4.   Assignee's Rights. Assignee shall have the right, but not the
             -----------------
obligation, to take, at Assignor's sole expense, any actions that Assignor is
required under this Assignment to take but which Assignor fails to take, after
fifteen (15) days' notice to Assignor. Assignor shall reimburse and indemnify
Assignee for all reasonable costs and reasonable expenses incurred in the
reasonable exercise of its rights under this section 4.

        5.   Inspection Rights. Assignor hereby grants to Assignee and its
             -----------------
employees, representatives and agents the right to visit, during reasonable
hours upon prior reasonable written notice to Assignor, any of Assignor's plants
and facilities that manufacture, install or store products (or that have done so
during the prior six-month period) that are sold utilizing any of the
Collateral, and to inspect the products and quality control records relating
thereto upon reasonable written notice to Assignor and as often as may be
reasonably requested.

action and to execute any instrument which Assignee may deem necessary or
advisable to accomplish the purposes of this Collateral Assignment, including:

                  (i)  To modify, in its sole discretion, this Collateral
Assignment without first obtaining Assignor's approval of or signature to such
modification by amending Exhibit A, Exhibit B and Exhibit C, thereof, as
appropriate, to include reference to any right, title or interest in any
Copyrights, Patents or Trademarks acquired by Assignor after the execution
hereof or to delete any reference to any right, title or interest in any
Copyrights, Patents or Trademarks in which Assignor no longer has or claims any
right, title or interest; and

                  (ii)  To file, in its sole discretion, one or more financing
or continuation statements and amendments thereto, relative to any of the
Collateral without the signature of Assignor where permitted by law.
