General

  ATG Inc. was incorporated in Texas in 1976 under the name Allied Nuclear,
Inc., reincorporated in California in 1980 and changed its name to "ATG Inc." in
1987.  ATG is a radioactive and hazardous waste management company that offers
comprehensive treatment solutions for low-level radioactive waste and low-level
mixed waste generated by the U.S. Department of Defense, the U.S. Department of
Energy and commercial entities such as nuclear power plants, medical facilities
and research institutions.  Our thermal treatment technologies achieve
substantial volume and mass reductions for treated waste streams while
encapsulating the non-volatile waste remains in a glass matrix or metal matrix
for final disposal.  Both of these final waste forms offer greater intrinsic
safety and environmental benefits at competitive prices than either incinerator
ash or non-thermal waste processing techniques.

  ATG operates through two primary business lines, the Fixed Facilities Group
and the Field Engineering Group. The Fixed Facilities Group operates ATG's fixed
facilities in Richland, Washington and Oak Ridge, Tennessee, which are used to
process low-level radioactive waste and low-level mixed waste.  The Fixed
Facilities Group also performs nuclear related work at its customer sites which
normally results in waste being sent to its fixed facilities for processing
prior to disposal. ATG's fixed facilities operate under radioactive material
licenses issued by the State of Washington for its Richland facilities and the
State of Tennessee for its Oak Ridge facilities.  Our radioactive materials
licenses include reciprocity provisions that allow us to treat radioactive waste
at customer sites in all fifty states.  Our licenses and permits for our
Richland, Washington facilities also include the most comprehensive mixed waste
processing permit in the United States.  Our mixed waste processing capabilities
resulted in substantial mixed waste revenue starting in 2000 which is expected
to continue in 2001 and is anticipated to help attract additional wastes to our
processing facilities for low-level radioactive waste.

  The Field Engineering Group performs a broad range of construction management
projects and hazardous waste remediation projects at customer sites.   Its
primary customer base is private industry and the Department of Defense. It
carries out both fixed price and time and materials contracts related to the
clean-up of customer sites under the U.S. Comprehensive Environmental Response,
Compensation and Liability Act of 1980, commonly referred to as CERCLA, and the
U.S. Resources Conservation and Recovery Act of 1976, commonly referred to as
RCRA, asbestos abatement projects, as well as various specialized construction
management projects, such as the construction of levies.

  In December 1998, ATG acquired assets and business lines from the former
Molten Metal Technologies, Inc. The assets acquired from Molten Metal
Technologies included substantially all of the operating assets, contracts,
licenses and permits associated with the wet waste treatment and catalytic
extraction processing for ion exchange resins used to clean various nuclear
power plant waste streams. During the quarter ended June 30, 2000, ATG announced
and completed a restructuring plan that was aimed primarily at improving cost
efficiencies and waste treatment processes. During the quarter ended December
31, 2000, ATG completed a review of the Tennessee fixed facilities
concerning the utilization of a modified Q-CEP thermal treatment system for the
processing of specialty niche waste streams. Due to the prohibitive cost and the
unknown prospect of success related to the proposed system modification, ATG
formally abandoned the Q-CEP thermal treatment system.

  We believe that we possess a number of competitive advantages which
distinguish our company from other radioactive and hazardous waste management
companies.  These include:

     .  a very comprehensive range of services;

                                       2
<PAGE>

     .  an extensive portfolio of licenses and permits that are both necessary
        to do business and that create barriers to entry for new competitors;

     .  the inherent cost-efficiency and environmental integrity of our waste
        treatment technologies; and

     .  our established positioning with commercial and government customers and
        federal, state and local regulators.

In particular, our radioactive material licenses and our mixed waste permits are
considered to be major competitive factors in our fixed facility business lines.
The very long time periods, ranging from three to five years, and extensive
public interactions required to obtain these licenses and permits constitute
extensive barriers to entry that we believe provide far greater protection
against competition than do the proprietary protections and patents associated
with the technologies that we employ.

Market Overview

  General.   The worldwide environmental services industry is diverse and
growing.  Both in the United States and abroad, this growth has been driven by
extensive legislation and governmental regulations that are aimed at protecting
the environment by requiring responsible parties to responsibly manage the
nuclear and hazardous wastes that they generate and to clean up any already
existing environmental hazards. According to the February 2000 report of the
U.S. Department of Energy entitled "Assessment of the Environmental Management
Industry", in 1998 U.S. companies generated $190 billion in environmental
industry related revenue on a worldwide basis representing approximately 2.0%
growth over 1997 revenue.

  Although much of the U.S. environmental market is mature and marked by
significant competition for environmental project work, we believe that the
specific environmental services markets that we focus on and, in particular, the
treatment and disposal of low-level radioactive waste and low-level mixed waste
as well as the decommissioning of facilities contaminated with those wastes,
face much more limited competition and thereby continue to command greater
margins than many other environmental service areas.  The following is a
description of each of the markets ATG focuses on relative to the types of waste
each market addresses.

  Treatment Market in Low-Level Radioactive Waste.   Radioactive waste is
categorized as either high-level radioactive waste or low-level radioactive
waste.  This waste is generated by government facilities and by commercial
enterprises such as nuclear power plants, medical laboratories and university
and industrial research and development facilities. High-level radioactive waste
is primarily comprised of spent nuclear fuel rods from nuclear reactors and
highly radioactive waste generated by the processing of nuclear materials for
weapons production. ATG does not handle or process high-level radioactive waste.
Low-level radioactive waste is all radioactive material other than high-level
radioactive waste.

  Low-level radioactive waste consists of relatively large amounts of common
industrial waste materials that have become contaminated during use with
generally small amounts of radioactivity.  These materials include equipment and
tools that have been used in nuclear facilities and laboratories; protective
clothing worn by radiation workers; and paper, rags, packing materials, and
miscellaneous liquids and sludges that are waste by-products from nuclear
manufacturing, power production, or medical or research applications. A special
case of low-level radioactive waste is ion exchange resins that are used to
clean various nuclear power plant process water streams. The ion exchange resins
act in a manner analogous to that of a magnet, pulling dissolved radioactive
ions out of the nuclear process water via a chemical attraction for those ions.
Through these cleaning processes, ion exchange resins tend to accumulate
significantly higher concentrations of radioactive materials than other low-
level radioactive waste which, accordingly, increases their handling and
disposal costs.

  ATG had targeted the ion exchange resin treatment market for its SAFGLAS(TM)
process in early 1998 and began offering thermal processing for resins with
relatively low contamination levels.  Our acquisition of the assets of Molten
Metal Technologies in December 1998 moved ATG into the leadership position for
ion exchange resin treatment offerings and allowed ATG to process ion exchange
resins with significantly greater levels of radioactive contamination, thereby
opening a broader spectrum of the ion exchange resin market to ATG.  ATG
currently is the only provider of the full range of services leading to the
final disposal of used ion exchange resins serving the U.S. market. These
services include dewatering the resins at customer sites or at ATG's fixed
facilities to meet disposal requirements, selling a spectrum of proprietary high
integrity containers that are required for the disposal of ion exchange resins
and other very radioactive materials, thermally processing ion exchange resins
to achieve large volume and mass reductions of 100 to 1, and providing shielded
transportation services via a large fleet of shielded casks in order to
transport the ion exchange resins in accordance with regulations of the U.S.
Department of Transportation and U.S. Nuclear Regulatory Commission, commonly
referred to as the NRC.

                                       3
<PAGE>

  ATG has been engaged in the business of handling, treating, storing, and
disposing of low-level radioactive waste since 1988.  As of December 31, 2000,
in ATG's estimation, ATG was providing at least one of its low-level radioactive
waste service lines to greater than 90% of the commercial nuclear power plants
in the United States.  ATG estimates that currently between $150 and $200
million is spent annually in the United States on the treatment of commercial
low-level radioactive waste.  We believe that the size of the commercial market
in the United States for treatment of low-level radioactive waste will continue
to increase over the next decade as the result of the expected decommissioning
of older nuclear power plants in the United States. We also believe that
significant demand exists in the United States for the volume and mass reduction
of commercially generated low-level radioactive waste, as there are at present
only two full-service disposal sites in the nation accepting this waste.
Moreover, one of those, Barnwell in South Carolina, has announced substantial
graduated cutbacks in the quantities of nuclear wastes it will accept that will
result in phasing out all wastes from outside the Atlantic Compact over the next
seven years.

  The Barnwell disposal site, which currently services the majority of
commercial low-level radioactive waste generators in the United States, has
increased its disposal fees by approximately 300% over the past five years.  The
current disposal fees at this site are approximately $4.00 to $7.00 per pound,
or $400 per cubic foot, depending upon the waste's density and activity levels.
The disposal fees charged by the disposal site in Richland, Washington, the
other fully permitted low-level radioactive waste disposal site, are
significantly lower than those charged by the Barnwell site, but this site is
only permitted to accept waste generated in the eleven Northwestern states.
There is also a disposal facility in Clive, Utah that also charges disposal fees
significantly lower than those charged by the Barnwell site, but it is currently
permitted to accept only low-level radioactive waste with lower concentrations
of radioactivity than that accepted by either Barnwell or the Richland site.

  At the present time ATG is the only company providing a full range of thermal
treatment services for low-level radioactive waste in the United States.  GTS
Duratek, Inc. provides incineration of some low-level radioactive waste but not
ion exchange resins. A new market entrant, Studvik Inc., began proving pyrolysis
services for ion exchange resins during 2000.

  The federal government, principally the Department of Energy and Department of
Defense, have generated very significant amounts of low-level radioactive wastes
that are largely stored on federal government sites.  Based on the February 1995
Department of Energy publication, "Environmental Management", ATG estimates that
the Department of Energy, which owns most of those wastes, has in excess of 53
million cubic feet of low-level radioactive waste either currently stored or
expected to be generated during the next 20 years at its facilities throughout
the United States. ATG estimates that the minimum processing value will exceed
$1.8 billion based on a processing cost of $35.00 per cubic foot.

  Treatment Market for Low-Level Mixed Waste.  Low-level mixed waste is low-
level radioactive waste co-mingled with hazardous substances regulated by RCRA
and/or toxic substances regulated by the Toxic Substances Control Act of 1976,
commonly referred to as TSCA.  Low-level mixed waste results from a variety of
activities such as the processing of nuclear materials used in nuclear weapon
production, nuclear energy research, and the generation of nuclear power.  The
clean-up of government-generated low-level mixed waste is driven by the Federal
Facilities Compliance Act of 1992 which requires that radioactivity-contaminated
federal facilities meet waste clean-up targets by specified dates.  For example,
the Department of Energy's Hanford Reservation was required to commence non-
thermal treatment of the low-level mixed waste stored there by September 30,
1999, and thermal treatment of this waste by December 31, 2000.  ATG, which the
Department of Energy contracted with to process this waste, commenced non-
thermal treatment of the waste by December 1999 and thermal treatment by
December 2000.  Although ATG's contract also required that we obtain all
licenses, permits and approvals for, and place our treatment facility for low-
level mixed waste in operation by November 10, 2000, ATG did not meet this
deadline due to the lack of completion of the demonstration testing of our
Richland facility.  The Department of Energy has been notified of the 2001
schedule for completion of demonstration testing and ATG's violation of the
November 10, 2000 deadline.  To date, the Department of Energy has not notified
ATG of any corrective actions nor has ATG obtained a waiver of this violation.

  Significant quantities of untreated low-level mixed waste have accumulated in
the United States, as approved treatment solutions applicable to a broad range
of low-level mixed waste streams have previously not been available.  The
Department of Energy estimates that there is in excess of 7.7 million cubic feet
of low-level mixed waste either currently stored or anticipated to be generated
over the next two decades throughout the United States at Department of Energy
facilities alone.  The Department of Energy also estimates that the treatment
costs for its low-level mixed waste will exceed one billion dollars through the
year 2010.  We are not aware of any reliable estimates of the existing backlog
of commercially generated low-level mixed waste awaiting treatment at
generators' sites, as there are no requirements for commercial generators to
report that information.  However, according to a national profile of
commercially generated mixed waste based on a 1998 survey sponsored by the NRC
and the U.S. Environmental Protection Agency, approximately 140,000 cubic feet
of low-level mixed waste was commercially generated in the United States in
1990.  We believe that the size of the commercial low-level mixed waste
treatment market in the

                                       4
<PAGE>

United States will increase significantly in connection with the expected
decommissioning of nuclear power plants in the United States over the next
decade.

  ATG has successfully permitted and financed, and has substantially completed
construction of, the most comprehensive commercial low-level mixed waste
treatment facility in the United States. That facility, a portion of which
commenced operations in December of 1999, will provide non-thermal treatment of
mixed wastes requiring stabilization under RCRA and will provide thermal
treatment of mixed wastes that require high temperature treatment under both
RCRA and TSCA to destroy hazardous constituents prior to disposal.  Currently,
the regulatory authorities are allowing ATG to process contracted mixed waste
streams as we prepare for demonstration testing for the thermal treatment of
mixed waste.  The regulatory agencies allow up to 720 hours, or with an
extension, up to 1440 hours, of waste stream processing prior to demonstration
testing.  After completion of these 720 hours, or 1440 hours if an extension has
been granted, ATG will no longer be able to process contracted waste streams
without successful completion of demonstration testing.  ATG is targeting three
months, or until about June 2001, to complete the initial 720 hours, and will,
if upon completion of these 720 hours it believes it could benefit from an
additional 720 hours of waste processing prior to demonstration testing, request
an extension for an additional 720 hours from the regulatory agencies.  ATG
believes an extension, which would allow it to continue thermal processing waste
while making any needed modifications prior to demonstration testing, would be
granted by the regulatory agencies.  To date, ATG has thermally processed
approximately 150 hours of contracted waste streams.  Once demonstration testing
of the Richland facility has commenced, if ATG's thermal processing systems do
not meet governmental standards, this would delay or prevent our Richland
facility from becoming operational for thermal decontamination of mixed waste,
resulting in a loss of significant revenue potential at this facility.
Demonstration testing of this facility for thermal treatment of mixed waste is
scheduled to be conducted during 2001.

  ATG has already won seven commercial and five federal contracts for the
treatment of mixed wastes and initiated the non-thermal treatment of mixed
wastes generated by the Department of Energy under one mixed waste contract in
December of 1999.  These contracts are anticipated to provide in excess of $67.6
million of revenues to ATG over the term of these contracts.  We anticipate
successful completion of demonstration testing during 2001 and anticipate that
all of our mixed waste treatment service lines will be operational in 2001.  In
the interim, we are processing thermal mixed waste streams pursuant to the 720
hour processing allowance provided by the regulatory authorities.

        Hazardous Waste Treatment Market.  Hazardous waste is waste that is
classified as hazardous under RCRA and/or toxic under TSCA.  The list of
"hazardous substances" covered by these laws is extensive and includes a large
number of chemicals, metals, pesticides, biological agents, toxic pollutants and
other substances.  ATG is not engaged in the large but highly competitive
hazardous waste treatment market other than through the environmental
restoration services provided by its Field Engineering Group.  Historically, ATG
has processed a broad range of hazardous substances at client sites during the
execution of environmental restoration projects.

   The core technology employed in the SAFGLAS(TM) and GASVIT systems is
vitrification. Vitrification technologies have been successfully used in Europe
for over thirty years, principally in the area of treatment of high-level
radioactive waste and are used by the Department of Energy currently for high-
level radioactive waste.  The EPA has identified vitrification as what it refers
to as the best demonstrated achievable technology for the treatment of high-
level radioactive waste.  We believe that vitrification will prove to be equally
effective in the treatment of waste contaminated with lower levels of
radioactivity.  In addition, the vitrification process results in significantly
less effluents than the more traditional incineration methods of waste
treatment.  Accordingly, we believe vitrification is widely perceived as an
environmentally superior waste treatment method.

  SAFGLAS(TM)-Thermal Treatment of Low-Level Radioactive Waste by Vitrification.
The SAFGLAS(TM) system treats a broad spectrum of low-level radioactive waste in
the form of dry active wastes, such as protective clothing, paper, rags,
plastics and wood, low-level activity resins, aqueous based liquids and sludges,
and oils, which eliminates the customer's need to presort wastes to fit the
specialized capabilities of a particular waste processor's technology.  The
SAFGLAS(TM) system can reduce the volume of the input waste by a factor of up to
200 to 1 and the mass of the input waste by up to 96%.  We believe that the
highly stable and leach-resistant nature of the glass produced by the
SAFGLAS(TM) process, as compared to incineration ash, will be significant for
waste generators concerned with the potential long-term liabilities associated
with the land disposal of low-level radioactive waste.

  The basic SAFGLAS(TM) system has been enhanced through the addition of a high
temperature bulk processing unit, commonly known as a BPU, that processes a wide
range of low-level radioactive waste.  Because the BPU exhausts into the second
chamber of the basic SAFGLAS(TM) unit, ATG refers to the combination of these
integrated technologies as the SAFGLAS(TM) system.  The BPU offers the advantage
of allowing each customer's waste to keep its own identity and not to be
commingled during processing.  We believe from that this will offer a
significant competitive advantage when the Barnwell site limits its acceptance
of wastes and some customers opt for having the waste processed for volume
reduction and then returned for on-site storage.

  GASVIT-Thermal Destruction of Low-Level Mixed Waste by Gasification/
Vitrification.  ATG has acquired licensing rights to use a proprietary plasma
arc technology developed by Integrated Environmental Technologies, LLC for the
treatment of low-level mixed waste.  We are integrating the plasma technology
from Integrated Environmental Technologies with our own technologies to form the
GASVIT system.  The GASVIT system will be used as the primary component in our
thermal processing facility for low-level mixed waste.  Materials are fed into a
process chamber where the organic materials are destroyed in a flameless
process.  As with the SAFGLAS(TM) system process, the end result of the GASVIT
system process is a glass material.  The GASVIT system can reduce the volume of
the input waste by a factor of up to 200 to 1, and the mass of the input waste
by a factor of up to 96%.  A 50 lbs./hr. prototype gasification/vitrification
process chamber has been in operation at IET's facilities in Richland,
Washington since June, 1997.  The GASVIT system is being licensed for a total
throughput of 12,000 pounds per day; however, the initial unit will provide only
50% of the permitted capacity.  We intend to add another unit as its capacity
needs increase.

  RESIN DECONTAMINATION-Non-thermal Washing and Separation of Ion Exchange
Resins. Ion exchange resins with significant radionuclide concentrations are
washed and separated in a licensed non-thermal mechanical process that removes
the radioactivity.  The process concentrates the radioactivity from ion exchange
resins into a small, stable, efficient and economical use of available disposal
space.

  WET WASTE SERVICES-Dewatering, packaging, and shielded transportation of Ion
Exchange Resins.  We hold patent and other rights for a variety of licensed high
integrity containers used to hold ion exchange resins during transportation and
disposal.  ATG also has the patent rights and ownership for approximately 50% of
the nation's heavily shielded casks that are used to safely transport ion
exchange resins in accordance with Department of Transportation regulations.
Additionally, ATG provides proprietary equipment and services to remove water
from ion exchange resins prior to transportation and disposal to meet Department
of Transportation and disposal site criteria, achieving in the process moisture
removal levels considerably beyond those achievable by competing technologies.

  AWPS - Advanced Treatment Through Filtration.  AWPS is used for the removal of
suspended and dissolved impurities from nuclear power reactor water streams.
ATG employs a variety of technologies for which it holds either patent or
licensing rights to treat a broad range of nuclear power plant liquid
waste/process streams.  Our proprietary processes pretreat the water in a manner
that increases the efficiency of filtration and the filter lifetimes ten-fold
greater than competing technologies.  One of our AWPS units was installed in a
commercial nuclear power plant in late 1999, one unit in 2000 and one unit is
scheduled for installation and testing at a commercial nuclear power plant in
2001.

  RVR-Radioactive Volume Reduction of Liquid Wastes and Sludges.  This patented,
moderate temperature, vacuum evaporation process provides a portable and
economic method for transforming radioactive liquids and sludges into dry
powders and, if desirable, recovering the water for reuse.  ATG employs RVR
systems at its Tennessee facilities to treat its own secondary wastes as well as
customer wastes. The RVR process has also been used for commercial nuclear
projects throughout the United States.  In addition, we also sell RVR units to
foreign power reactor operators.

  Operations and Services

  ATG provides radioactive and hazardous waste management services through its
Fixed Facilities Group and its Field Engineering Group.

  Fixed Facilities Group.  The Fixed Facilities Group operates ATG's treatment
facilities for low-level radioactive waste and low-level mixed waste in
Richland, Washington and Oak Ridge, Tennessee and also provides shielded
transportation services and on-site services at its customers' facilities. The
primary treatment facilities are located on a 45-acre parcel of land owned by
ATG in Richland, Washington which is adjacent to the Department of Energy's
Hanford Reservation. Our Richland facility is one of the largest commercial
radioactive waste treatment facilities in the United States.  This facility is
currently licensed to handle, treat and store a wide variety of low-level
radioactive waste. In addition, the facility is currently licensed to handle,
treat and store a wide variety of non-thermal low-level mixed waste and must
complete its demonstration testing to become fully operational for thermal low-
level mixed waste treatment for both commercial and government generators. ATG
also owns a 40,000 square foot licensed facility on a seven acre site in Oak
Ridge, Tennessee where it thermally processes ion exchange resins and non-
thermally processes both ion exchange resins and radioactive sludges that are
not suitable for thermal processing.  ATG also owns a third licensed site, a 16
acre facility in Columbia, South Carolina which is used to maintain and store
equipment used for wet waste field projects throughout the United States.
Finally, ATG leases a four-acre facility in Fremont, California which houses
ATG's corporate offices, as well as a storage and transfer station for low-level
radioactive waste that supports its Richland operations.  ATG utilizes a fleet
of company-owned trucks to transport waste intra-state to or from its Richland
and Fremont facilities, and utilizes third party commercial carriers to
transport waste inter-state to or from these facilities.

  Treatment Services for Low-Level Radioactive Waste.  Since 1988, ATG has
treated and recycled several million pounds of low-level radioactive waste at
its Richland facilities.  Since being placed in operation in September 1997, the
SAFGLAS(TM) system has processed in excess of 4 million pounds of low-level
radioactive waste.  In addition to the Department of Energy, Department of
Defense and other agencies of the U.S. government, customers for the company's
low-level radioactive waste treatment services include over 90% of the nation's
nuclear power plants, many major corporations, and numerous universities,
laboratories, hospitals and other research and medical institutions.

  Treatment Services for Low-Level Mixed Waste.  In early 1995, ATG began the
licensing, design and facility construction process for a mixed waste treatment
and storage facility to be sited at its Richland facilities.  That permit was
issued in July 1999 and construction of the facility commenced shortly
thereafter financed by the proceeds from the issuance of $27 million in tax-
exempt Solid Waste Revenue Bonds by the Port of Benton in Washington State.

  The construction of ATG's mixed waste facilities is being carried out in a
phased manner so that those portions of the facility that can be brought on line
more rapidly are completed and made operational first.  Accordingly, although
the overall facility will not be fully operational until sometime in 2001, we
were able to successfully receive and process non-thermal mixed wastes in late
1999 and throughout 2000.  The mixed waste processing can generally be
categorized as thermal and non-thermal consistent with requirements established
by the EPA that dictate how various types of mixed wastes must be processed
prior to disposal.

  Non-thermal mixed waste processes are generally intended to chemically
stabilize mixed waste materials and/or encapsulate the wastes in a manner that
renders them sufficiently immobile for land disposal.  Our permit provides for
four non-thermal mixed waste process lines designed to meet the EPA's RCRA mixed
waste treatment specifications.  Our mixed waste permit also provides for one
thermal process line that is designed to thermally destroy RCRA and TSCA organic
constituents in the mixed wastes that the EPA has determined require thermal
destruction prior to disposal.  We use a proprietary high temperature plasma
process to destroy RCRA and TSCA organic mixed wastes.  That process, which the
company calls "GASVIT", destroys the organic constituents in the mixed wastes in
a manner that fully meets the EPA requirements without the use of incineration.

  In November 1995, the Department of Energy awarded ATG, in a competitive
bidding process, the first privatized contract to thermally treat low-level
mixed waste generated by the Department of Energy's Hanford Reservation.  This
contract has a minimum value to ATG of $10.4 million and a maximum value to ATG
of $24 million for treating 175,000 cubic feet of waste over ten years.
Subsequently, in September 1997, the Department of Energy awarded us the first
privatized contract to non-thermally treat low-level mixed waste generated by
the Hanford Reservation.  This contract has a minimum value to ATG of $2.6
million and a maximum value to ATG of $5 million over a three-year period which
commenced in December 1999 when we began to non-thermally treat low-level mixed
waste under that contract.  More recently we have been awarded several
additional contracts to treat mixed wastes generated by several other Department
of Energy facilities across the United States, by various commercial research
and manufacturing companies, and by commercial nuclear utility companies.

  ATG commenced the non-thermal treatment portion of these contracts in December
1999.  ATG has also commenced the thermal treatment portion of these contracts
in December 2000 by the start-up treatment of contracted thermal mixed waste
streams.

  Field Engineering Group.  The principal services provided by ATG's Field
Engineering Group are the environmental restoration of sites contaminated with
hazardous wastes and  construction management contracts such as levee
construction.  Our comprehensive capabilities include site investigation,
characterization and assessment, negotiation with regulatory agencies and
procurement of required regulatory approvals, preparation of feasibility and
remedial design studies, removal and remediation actions, construction, waste
brokerage and transportation.

  Decontamination and Decommissioning Services.  Historically, providing
services for decontamination and decommissioning of facilities contaminated with
radioactivity, commonly referred to as D&D, have been ATG's core specialty area.
ATG has been involved in D&D projects for over a decade and currently is
involved in several D&D projects for the Department of Energy.  Customers for
ATG's D&D services include nuclear power plants, universities and other research
institutions that utilize radioactive isotopes in a variety of research
projects, hospitals with radiological medicine departments, companies employing
nuclear materials in manufacturing and the Department of Energy and Department
of Defense, which oversee the nation's nuclear weapon production facilities.

                                       8
<PAGE>

  We believe that there are significant near-term opportunities in domestic D&D,
particularly in the commercial D&D market, as up to ten U.S. nuclear power
plants are expected to be decommissioned over the next decade. Based on recent
studies prepared by utilities regarding the costs to decontaminate and
decommission nuclear power plants, as reported by the Nuclear Energy Institute,
a nuclear energy industry policy organization, we estimate that the average
total cost of decontaminating and decommissioning a domestic nuclear power plant
is approximately $300-$400 million.  In addition, based on a 1996 Baseline
Environmental Management Report prepared by the Department of Energy, there are
over 5,000 radioactivity-contaminated Department of Defense and Department of
Energy facilities which are scheduled to be decommissioned over the next decade.

  Environmental Restoration Services.  ATG has historically concentrated on
environmental removal and remediation actions at contaminated Department of
Defense sites.  ATG estimates that there are over 420 Department of Defense
sites contaminated with low-level radioactive waste or low-level mixed waste.
According to a February 2000 report of the Department of Energy entitled
Assessment of the Environmental Management Industry, subcontracted spending by
the Department of Energy for environmental remediation in 1998 was $1.85
billion, up 7% from 1997, and is projected to continue growing for 10 to 15
years. ATG estimates that environmental restoration spending by the Department
of Defense is approximately 50% of Department of Energy spending, or
approximately $0.94 billion, for 1998.

  Since 1989 ATG has executed more than 237 field-engineering projects relating
to the environmental restoration of sites contaminated with low-level
radioactive waste, low-level mixed waste, or hazardous waste throughout the
United States and U.S. territories.

  For its military and industrial clients, ATG executes environmental
restoration projects either on a planned or quick response basis.  In the
execution of both planned and quick response environmental restoration projects
involving both low-level radioactive waste and low-level mixed waste, ATG
believes that it is one of only six domestic companies having the in-house
capability of providing on-site full-service solutions from site investigation
through the waste treatment stage for D&D and environmental restoration projects
involving low-level radioactive waste and low-level mixed waste.

  Revenues of Fixed Facilities Group and Field Engineering Group.  Prior to
1998, ATG evaluated its operations as one business unit.  Thermal processing of
large volumes of waste began in 1998 and ATG commenced evaluating its business
as two business segments in the fourth quarter of 1998.  ATG segregates revenue
and gross profit by business segment.  Selling, general and administrative
expenses are not allocated to the business segments.

  For the year ended 1998, the Fixed Facilities Group had revenue of $18,889,000
and gross profits of $11,082,000.   For the year ended 1999, the Fixed
Facilities Group had revenue of $46,854,000 and gross profits of $22,845,000.
For the year ended 2000, the Fixed Facilities Group had revenue of $33,318,000
and gross profits of $11,735,000.

  For the year ended 1998, the  Fixed Engineering Group had revenue of
$17,011,000 and gross profits of $5,002,000.   For the year ended 1999, the
Fixed Facilities Group had revenue of $13,808,000 and gross profits of
$1,458,000.    For the year ended 2000, the  Fixed Facilities Group had revenue
of $8,354,000 and gross profits of $1,338,000.

Customers

  We provide our services to a broad range of commercial and federal, state and
local government clients in the United States.  Demand for our services and the
distribution of this demand are influenced by the level of implementation and
enforcement of existing and new environmental regulations, funding levels for
government projects and spending patterns of commercial clients.

  Primarily due to our technical expertise, extensive portfolio of environmental
licenses and permits and full-service capabilities on-site, we have successfully
bid on and executed a substantial number of waste treatment, environmental
restoration, D&D and other contracts with commercial customers, the Department
of Defense, Department of Energy and a number of other federal government
agencies, as both a prime contractor and as a subcontractor.  In general, our
business mix has recently been trending towards an increase in the percentage of
revenue attributable to commercial clients, due to the commercial business
volume handled by our fixed facilities since the commencement of SAFGLAS(TM)
operation in late 1997 and our acquisition of the assets of Molten Metal
Technologies in late 1998.  In fiscal 2000, 1999, and 1998, the percentage of
our total revenue attributable to federal government contracts was approximately
30%, 27% and 55%, respectively. While we expect our commercial revenues to
continue to grow, the fact that most of the mixed waste in the United States is
owned by the federal government is anticipated to result in significant growth
in its federal revenue as well.  One contract with the U.S. Air Force accounted
for 14% of our total revenue in the year ended December 31, 1998.

                                       9
<PAGE>

We also serve numerous commercial clients, including large industrial concerns,
nuclear power plants, hospitals, laboratories and other medical institutions,
and universities. No single commercial client accounted for 10% or more of our
revenue in fiscal years 2000, 1999 or 1998.

Sales and Marketing

  ATG relies on a direct sales and marketing staff of approximately 10
employees, its executive management team and project managers, and brokers and
other intermediaries, to market its waste treatment and field engineering
services nationwide and internationally.  Historically, we relied on discrete
waste treatment projects and limited term remediation projects that typically
involved planned clean-ups of sites that were contaminated in the normal course
of manufacturing activity or quick response clean-ups of spills.  We now target
our marketing efforts on large, multi-year private sector and government site-
specific and term contracts in the areas of treatment of low-level radioactive
waste and low-level mixed waste, environmental restoration and nuclear facility
D&D.

  We focus our marketing resources on higher margin markets where we have
technological or licensing advantages over potential competitors.  We also focus
on continually strengthening our relationships with existing and target
customers.  We believe that relationship selling is important as customers
display an increasing desire for good, reliable service.  Accordingly, we deploy
operators at customer sites and target a high frequency of quality customer
interactions by our sales force directed at better identifying and resolving its
customers' problems.

  We also intend to offer our SAFGLAS(TM) and GASVIT vitrification technologies
for on-site treatment of low-level radioactive waste and low-level mixed waste
in selected Pacific Rim markets.  We believe that the high cost of disposal of
low-level radioactive waste and low-level mixed waste disposal in a number of
Pacific Rim countries favors thermal treatment for low-level radioactive waste
and low-level mixed waste, while regulatory restrictions and other environmental
concerns may limit incineration as a treatment process.

  To further promote use of its technologies and to establish strategic
alliances designed to accelerate its penetration of selected Pacific Rim
markets, ATG has entered into exclusive technology transfer agreements covering
its technologies for Hong Kong, Taiwan, and The People's Republic of China.  ATG
currently has two technology transfer agreements.  One of these agreements,
dated September 30, 1997, is with Alliance Technology Group, Incorporated, and
the second agreement, dated June 28, 1997, is with Pacific Trading Company.
These agreements require ATG to provide assistance and know-how to its alliance
partners who, in turn, have the right to market ATG's technologies in these
territories.  ATG will share in any profits generated from those efforts and
will also receive a royalty on revenue generated by the use of its vitrification
technologies.  ATG is entitled to independently pursue opportunities or to
terminate the agreements within those territories if its alliance partners are
not actively and successfully marketing its technologies, or, if designated
levels of minimum revenues are not achieved in those territories within
specified periods.  Although we believe that these agreements and similar
agreements may become important to our business in the future, our two existing
agreements are not material to our business because there is no current activity
and no revenues are being generated under those agreements.

Competition

  In general, the radioactive and hazardous waste management industry is highly
competitive. We face varying levels of competition in our current and planned
business lines. We believe that we currently have only one principal competitor,
Duratek, for the thermal treatment of domestic low-level radioactive waste, a
handful of small to mid-size competitors in the non-thermal treatment of
domestic low-level radioactive waste, and one potential competitor for thermally
treating ion exchange resins.  We have a non-compete agreement with Duratek that
precludes Duratek from processing commercial ion exchange resins.  The term of
the non-compete with Duratek expires December 2001.  When the non-compete
agreement with Duratek expires, we believe it will have a negligible effect on
the volume of ion exchange resins processed by ATG as ATG to date has only
received modest revenues from the ion exchange resins processing market.  With
respect to the domestic treatment market for low-level mixed waste, we believe
that there are only four other companies currently commercially processing low-
level mixed waste at their own facilities, all of which are doing so under
limited licenses which restrict them from accepting a broad spectrum of low-
level mixed waste streams. We believe that our mixed waste permit and mixed
waste processing facility provide the most comprehensive commercial mixed waste
treatment capabilities in the United States.

  We also face competition from disposal facilities for low-level radioactive
waste in that the volume and mass reduction achieved by our processing must be
at a cost that provides an economic incentive to the generator relative to the
options of direct disposal at a facility, as most low-level radioactive waste
does not require treatment in order to meet the acceptance criteria of at

                                       10
<PAGE>

least one U.S. facility. For example, when the commercial disposal site for low-
level radioactive waste in Clive, Utah recently expanded its acceptance
criteria, allowing it to receive waste with radioactivity levels higher than it
was previously permitted to accept, we saw a greater level of competition for
the affected wastes, as some generators in the geographic area proximate to this
facility that previously would have had the waste treated prior to disposal have
found it economical to apt for direct disposal. While we are aware that one or
more other companies are interested in developing commercial disposal sites for
low-level radioactive waste, the likelihood of their success does not appear to
be high based upon the public sensitivity to radioactive materials in the United
States. Nonetheless, any change in the pricing of licensed commercial disposal
of low-level radioactive waste in the United States will affect the competition
we face, with increasing prices decreasing the competition and decreasing prices
increasing the competition which we face.

  The nuclear facility D&D market is highly competitive, with numerous companies
of varying size, geographical presence and capabilities participating in a
variety of niche areas.  The two predominant trends are for nuclear facility
owners to either procure the services of a large engineering construction
company to be the general manager for D&D services or for the owners to self
perform the general management function. We believe that fewer than six
companies have the capability of fulfilling the general management role for
commercial nuclear power plant D&D, and that none of those companies nor owners
also have sufficient in-house commercial waste processing capabilities to fully
address the waste management issues presented by D&D. We believe that this will
require the general managers for commercial nuclear power plant D&D activities,
whether a contractor or the owner, to procure the services of one of the two
full service nuclear waste processing companies to assist them with waste
management.  We further believe that the forward going trend will be for the
general managers to avail themselves of the services of more than one waste
processing company in order to ensure competitive pricing for D&D waste
management services.

  We believe that the principal competitive factors applicable to all areas of
our business are price, breadth of services offered, range and breadth of
environmental licenses and permits held, reputation for customer service and
dependability, technical proficiency and environmental integrity, operational
experience, quality of working relations with federal, state and local
environmental regulators and proximity to customers and licensed waste disposal
sites.  We believe that we are, and will continue to be, able to compete
favorably on the basis of these factors.  We also believe that we have several
competitive advantages, including our vitrification and ion exchange resins
technologies, the patents we hold, broad range of environmental services
offered, ability to provide in-house full-service environmental solutions at
customers' sites, the range and breadth of environmental licenses and permits
held and applied for, including, without limitations, our radioactive material
licenses and mixed waste permits, geographical positioning, and integrated
technological approach to waste treatment solutions.

  Many of our competitors have substantially greater managerial, technical and
marketing resources than we do, and there can be no assurance that one or more
of our competitors do not possess or will not develop waste treatment
technologies or field service capabilities that are superior to or more cost
effective than ours.  In some aspects of our business, substantial capital
resources are required for facilities and equipment, and many of our competitors
have substantially greater financial resources than ATG.

Intellectual Property

  We regard aspects of our waste treatment technologies and know-how as
proprietary and use a combination of trade secret and trademark laws, employee
and third party non-disclosure agreements, licenses from owners of patents and
other intellectual property rights, and other methods to protect our
technologies and know-how.  We have received a patent for the SAFGLAS(TM) system
as incorporating a multi-zone process chamber.  We hold a number of patents on
the thermal and non-thermal processes and equipment which we utilize for
processing of ion exchange resins at our Oak Ridge, Tennessee facilities and at
our customer's sites, as well as for the high integrity containers and shielded
shipping casks used for the transportation of ion exchange resins.  We also hold
the licenses and permits for our Washington and Tennessee facilities and possess
the engineering craft knowledge required to cost-effectively operate, maintain,
and enhance the permitted status of those facilities.  While our patents provide
us with technological efficiency and provide us with revenue through licenses to
other companies by means of technology transfer agreements, we believe that the
ownership of patents is not presently a significant factor in our business and
that our success does not depend on the ownership of patents.  We cannot assure
you that we will be successful in protecting the proprietary aspects of our
technology, nor that our proprietary rights will preclude competitors from
developing waste treatment technologies equivalent or superior to ours.  In
addition, effective protection for the proprietary aspects of our technologies
may be unavailable or limited in many foreign countries.  While we are not aware
that any of our waste treatment technologies infringe the rights of any third
parties, we cannot assure you third parties will not claim infringement by ATG
with respect to its existing or future waste treatment technologies.

  From time to time we license the rights to use the intellectual property of
third parties embodied in subsystems of our technologies.  In particular, we
license rights from the owner of the patented technology embodied in the basic
SAFGLAS(TM)

                                       11
<PAGE>

system melter and from Integrated Environmental Technologies in connection with
the design, construction and use of the melter incorporated into the GASVIT
system. The former license is non-exclusive and royalty-free, but requires ATG
to pay to the owner of the patent a license fee in the amount of $35,000 for
each SAFGLAS(TM) process chamber built by ATG during a five-year period. With
respect to any melter we purchase from Integrated Environmental Technologies,
other than the two units we have initially contracted to purchase, our license
with Integrated Environmental Technologies requires the payment of a royalty fee
to Integrated Environmental Technologies in the amount of 3% of the gross
revenue generated by ATG from processing radioactive waste using a treatment
system incorporating such a melter. ATG from time to time receives letters of
inquiry from the owners of patents requesting that ATG demonstrate that the
technology licensed to ATG by third parties does not infringe their patents. We
routinely refer these letters of inquiry to the licensors, who are required
pursuant to the terms of their license agreements with ATG to defend ATG against
infringement claims asserted by third parties relating to the licensed
technology and to indemnify ATG against any resulting losses. With respect to
each letter of inquiry previously received by ATG, we have been advised by the
licensor that, in the judgment of the licensor, the licensed technology as used
by ATG did not infringe the subject patents.

  We require each of our technical and engineering employees to enter into
standard agreements pursuant to which the employee agrees to keep confidential
all proprietary information of ATG and to assign to ATG all rights in any
proprietary information or technology developed by the employee during his or
her employment or made thereafter as a result of any inventions conceived or
work done during his or her employment.  Despite these precautions, it may be
possible for a third party to copy or otherwise obtain and use our technology
without authorization or to develop similar technology independently.

Environmental Laws and Regulations; Licensing Processes Applicable to Treatment
Facilities for Low-Level Radioactive Waste and Low-Level Mixed Waste

  Environmental Laws and Regulations.  Extensive and evolving environmental
protection laws and regulations have been adopted in the United States during
recent decades in response to public concern over the environment.  Our
operations and those of our customers are subject to these evolving laws and
regulations.  The requirements of these laws and regulations impose substantial
potential liabilities.  For example, a failure to comply with current or future
regulations could result in substantial fines, suspension of production,
alteration of manufacturing processes, cessation of operations, or the
expenditure of substantial clean-up costs.  The requirements also create a
demand for many of our services.

  We believe that our compliance with environmental laws and regulations will
not have a material effect on our capital expenditures, earnings or competitive
position, except with respect to capital expenditures for environmental control
facilities.  We had $6.5 million in expenditures for environmental control
facilities in 2000, primarily in connection with the construction of the
Richland mixed waste facility; however, we expect that the amount of
expenditures for environmental control facilities required to be made in 2001
and immediate subsequent years will be less than $100,000.  ATG does, however,
expect to spend approximately $2,000,000 in 2001 to conduct demonstration
testing of its Richland facility.

  Under the Atomic Energy Act of 1954, commonly referred to as the AEA, and the
Energy Reorganization Act of 1974, the NRC regulates the receipt, possession,
use and transfer of radioactive materials.  Pursuant to its authority under the
AEA, the NRC has adopted regulations that address the management and disposal of
low-level radioactive waste and that require the licensing of commercial
disposal sites for low-level radioactive waste.

  RCRA provides a comprehensive framework for regulation of the handling,
transportation, treatment, storage and disposal of hazardous waste.  Strict
standards are imposed under RCRA on hazardous waste generators and transporters,
and on operators of hazardous waste treatment, storage and disposal facilities.
The Land Disposal Restrictions developed under the Hazardous and Solid Waste
Amendments of 1984 prohibit land disposal of specified wastes unless these
wastes meet or are treated to meet best demonstrated achievable technology
treatment standards, subject to specified exemptions.  Under current
regulations, waste residues derived from listed hazardous wastes are generally
considered to be hazardous wastes subject to RCRA standards unless they are
delisted through a formal rulemaking process that may last for several years.
Liability under RCRA may be imposed for improper handling, transportation,
treatment, storage or disposal of hazardous wastes, or for failure to take
corrective action to address releases of hazardous wastes.

  CERCLA, and subsequent amendments including the Superfund Amendments and
Reauthorization Act, commonly referred to as SARA, imposes strict, joint and
several liability upon owners or operators of facilities where a release of
hazardous substances has occurred, upon parties who generated hazardous
substances that were released at these facilities and upon parties who arranged
for the transportation of hazardous substances to these facilities.  Liability
under CERCLA may be imposed on ATG if releases of hazardous substances occur at
treatment, storage, or disposal sites used by ATG.  This liability potentially

                                       12
<PAGE>

extends to off-site storage and disposal facilities used by ATG, any facilities
owned by ATG for treatment and storage of low-level mixed waste, and releases at
a customer's facility caused by ATG.  Because our customers also face the same
type of liabilities, CERCLA and SARA create incentives for our potential
customers to avoid off-site treatment and disposal of hazardous substances in
favor of on-site treatment and recycling.

  The radioactive and hazardous components of low-level mixed waste are governed
by separate sets of laws and regulations discussed above.  The radioactive
component is governed by the AEA and is regulated by the Department of Energy
for waste at Department of Energy facilities and by the Nuclear Regulatory
Commission for commercially generated waste.  The hazardous waste component is
governed by RCRA, CERCLA, and/or TSCA, and is regulated by the EPA, and by the
laws of the individual states.  ATG designs its treatment and processing systems
for low-level mixed waste and hazardous waste with the goal of minimizing the
potential for release of hazardous substances into the environment.  In
addition, we have developed plans to manage and minimize the risk of CERCLA or
RCRA liability, including the training of operators, use of operational controls
and structuring of its relationships with the entities responsible for the
handling of waste materials and by-products.

  The Clean Air Act of 1970 imposes strict requirements upon owners and
operators of facilities and equipment which emit pollutants into the
environment, including incinerators.  Although we believe that our waste
treatment systems effectively trap most particulates and generally prevent
hazardous emissions from being released into the environment, we are required to
secure additional permits from local authorities responsible for implementing
the Clean Air Act.

  TSCA provides the EPA with the authority to regulate various types of
commercially produced chemical substances.  TSCA also established a
comprehensive regulatory program for polychlorinated biphenyls, commonly
referred to as PCBs, which is analogous to the RCRA program for hazardous waste.

  Other federal, state, and local environmental, health and safety requirements
may also be applicable to our business.  For example, the federal Occupational
Safety and Health Act imposes requirements designed to protect the health and
safety of workers, and the Nuclear Regulatory Commission has set regulatory
standards for worker exposure to radioactive materials.  In addition, the
requirements of various other statutes, including the Federal Facilities
Compliance Act of 1992 and the Uranium Mill Tailings Radiation Control Act, may
create opportunities for additional use of our services.

  Licensing Processes Applicable to Treatment Facilities for Low-Level
Radioactive Waste and Low-Level Mixed Waste.  The process of applying for and
obtaining the licenses and permits necessary to operate a radioactive waste
treatment facility is lengthy and complex.  The basic requirement is to obtain a
radioactive materials license from the state in which the facility is to be
located.  The first step in this process is securing site and land use
designation approval from local authorities.  Most local authorities require a
public hearing before a land use designation approval is granted.  Due to public
concern about the safety of radioactive material handling, the initial site
approval step is often the most difficult.  Upon site approval, the applicant
must submit an application to the NRC or the state's nuclear regulatory agency
if the state has signed an agreement to implement the NRC's regulations.  This
stage of the process may take two years or longer, and in some cases, may result
in denial of a license.  If the applicant intends to use a thermal treatment
method at its site, then additional permits would be needed from the local
authorities responsible for implementing the Clean Air Act regulations.  The
process for approving a thermal treatment method will generally include public
hearings, environmental assessments and numerous interactions with regulators to
resolve licensing and permitting issues.

  The licensing requirements applicable to a mixed waste facility are even more
complex.  In addition to the steps summarized above, the applicant must submit a
RCRA Part A and Part B permit application to the appropriate agencies.  For
processing of PCBs, a TSCA permit from the EPA must also be obtained.  In
parallel with the RCRA/TSCA Part B permitting process, the applicant must submit
an application to the agencies that issue radioactive material licenses and
those that issue permits pursuant to the Clean Air Act.  Several revisions to
each document submitted may have to be made before the review process is
complete and the application is granted.  From the time the initial application
is filed, the mixed waste licensing and permitting process could take as long as
five years.

  We initiated the mixed waste licensing process for our Richland facilities in
1995 and commenced non-thermal mixed waste treatment there in the fourth quarter
of 1999.  In March of 1995, the company submitted a siting application to the
Washington State Department of Ecology.  After conducting two different public
hearings, WDOE approved our siting application in December of 1995.  Immediately
after procuring this approval, ATG submitted a RCRA Part A and Part B permit
application to WDOE for an integrated waste treatment plant utilizing
stabilization, macro-encapsulation, physical extraction and other non-thermal
treatment processes.  In 1996, the application was amended to include the
processing of mixed wastes using the GASVIT thermal treatment technology.  A
copy of the application was also submitted to the EPA for a joint EPA/WDOE
permitting process covering PCBs under TSCA regulation. Currently, the
regulatory authorities are allowing ATG to process contracted

                                       13

waste streams as we prepare for demonstration testing. We presently anticipate
completion of our thermal demonstration testing during 2001.

  We are required to obtain a radioactive waste import permit from the NRC when
we are engaged in the business of treating low-level radioactive waste and low-
level mixed waste received from foreign generators at our fixed facilities.

Employees

  At December 31, 2000, ATG employed 353 full-time employees.  To date, ATG has
been successful in attracting and retaining qualified managerial and technical
personnel, although we cannot assure you that this success will continue.

  At December 31, 2000, 132 of our employees were represented by labor unions
under collective bargaining agreements.  We cannot predict whether any of our
employees who currently are not represented by unions will elect to be so
represented in the future.  We consider our relations with our employees to be
good and have never experienced a work stoppage or strike.

Factors Affecting Future Operating Results

  ATG's business is subject to the following risks and uncertainties, in
addition to those described elsewhere.

  We are in default under one of our credit facilities; as a result, our lenders
could at any time elect to accelerate repayment of all amounts owed under the
credit facilities.  ATG is in violation of a requirement under one of its credit
facilities to make a mandatory paydown of approximately $5,750,000 by June 30,
2000, is late in paying interest amounts in the last quarter of 2000 totaling
$765,443, late in paying interest amounts in the first quarter of 2001 totaling
$715,634, late in paying fee amounts in the last quarter of 2000 totaling
$60,035, and late in paying a letter of credit fee amount in the first quarter
of 2001 totaling $218,640 due under its credit facilities, and is in violation
of financial covenants in the credit facility agreements.  ATG also was unable
to pay a $1,500,000 short-term loan from an individual lender that was
originally due on October 5, 2000 and was subsequently extended to December 15,
2000.  ATG is seeking to obtain an extension of the December 15, 2000 due date,
but to date has not obtained this extension.  ATG will not be able, without
obtaining concessions from its banks or obtaining new financing, to make the
mandatory $5,750,000 paydown, to bring its interest payments current, to comply
with current financial covenants in the credit facility agreements or to repay
its $1,500,000 loan.  At any time ATG's lenders could elect to enforce their
rights and remedies under the credit facilities agreements to accelerate
repayment of all amounts owed.   ATG does not have the funds to repay all its
loans if the lenders accelerate repayment.  See "Management's Discussion and
Analysis of Financial Condition and Results of Operations - Liquidity and
Capital Resources."

  We may not be able to continue as a going concern if our lenders elect to
accelerate the payment of indebtedness under our credit facilities.  Since we do
not currently have sufficient funds to repay all of our indebtedness under our
credit facilities, we may not be able to continue as a going concern if our
lenders elect to accelerate payment under the credit facilities.  In that case,
we would likely become insolvent and subject to voluntary or involuntary
bankruptcy proceedings, and the value of our equity securities would likely be
significantly diminished. The report of our independent auditors appearing in
this report includes a "going concern" qualification.

  If we cannot raise additional capital, we may not be able to implement and
complete testing of our Richland, Washington mixed waste facility, pay-off our
debts, meet our business expenses, or otherwise implement our business plan.  We
believe that ATG will need additional financing for working capital and capital
expenditure requirements in order to implement its long-term business plan.   If
we are not successful in raising additional working capital we may not be able
to implement and complete thermal demonstration testing of our Richland,
Washington mixed waste facility which is currently scheduled for testing in 2001
and to make mandatory paydowns and payoffs of loans currently due or which will
be due in 2001.  Our working capital deficit as of December 31, 2000 is $35.2
million, a decrease of $38.5 million from working capital of $3.3 million at
December 31, 1999.  The working capital excludes restricted cash of $16.0
million and accounts payable of $3.5 million at December 31, 1999, that are
exclusively for the construction of ATG's Richland, Washington facility.   If we
are not successful in raising additional capital, we may need to curtail or
scale back our planned operation of this facility.  See "Management's Discussion
and Analysis of Financial Condition and Results of Operations - Liquidity and
Capital Resources."

  We have experienced a downward trend in our revenue and net income for fiscal
2000.  To date, we have experienced a downward trend in revenue and net income
for fiscal 2000 compared to fiscal 1999, and those trends will continue if we
cannot generate significant additional revenues in our Oak Ridge, Tennessee and
Richland, Washington facilities.  ATG recorded revenue of $41.7 million and a
net loss of $25.5 million for the fiscal year ended December 31, 2000, compared
to revenue of $60.7 million and net income of $5.2 million for 1999.  The
decrease in revenue and net income was principally due to a major

                                       14
<PAGE>

shortfall in receipts from spent ion exchange resin at our Oak Ridge facility, a
consolidation of our operations and workforce reduction at our Oak Ridge
facility in the second quarter of fiscal 2000, the transition of our thermal
waste processing system at our Oak Ridge facility to a more cost effective non-
thermal resin decontamination process which commenced in the second quarter of
fiscal 2000, and the plant write-off and abandonment expenses at our Oak Ridge
facility in the fourth quarter of 2000. As a result of the restructuring of the
Oak Ridge facility, ATG recorded a $500,000 inventory write-down charge to cost
of revenue and a $1.9 million restructuring charge in the second quarter of
fiscal 2000. During the fourth quarter of 2000, the Company completed a review
of the Tennessee fixed facilities concerning the utilization of a modified Q-CEP
thermal treatment system for the processing of specialty niche waste streams.
Due to the prohibitive cost and the unknown prospect of success related to the
proposed system modification, the Company formally abandoned the Q-CEP thermal
treatment system during the fourth quarter of 2000 and recorded a non-cash asset
impairment charge of $14.1 million. In addition, the Company recorded non-cash
charges regarding the $1.4 million write-down of goodwill from its acquisition
of the Q-CEP assets, a $307,000 maintenance supply inventory write-down that was
charged to cost of revenue, and an $828,000 write-down of other assets.
Furthermore, a charge of $1.2 million was recorded for processing and disposal
of secondary waste associated with the shutdown of the Q-CEP facility, of which
$1.0 million remains unpaid at December 31, 2000. The Q-CEP thermal treatment
process was utilized for the treatment of ion exchange resins from nuclear power
plants. The company is continuing the pursuit of its non-thermal resin
decontamination technology for the treatment of ion exchange resins.
Additionally, ATG has completed construction and is processing low level mixed
waste steams as we prepare for demonstration testing in 2001 of our new thermal
mixed waste facility in Richland, Washington. In the absence of significant
revenue generation at these facilities, ATG will continue to experience this
downward trend in revenue and net income for the foreseeable future.

     The book value and earnings per share of our common stock may be diluted
significantly and the price of our common stock may also decline because of our
current and future obligations to issue additional shares of common stock to the
selling shareholders, holders of outstanding options and warrants, and
purchasers in future equity financings. Under agreements with the selling
shareholders, ATG is currently required to issue a total of 578,875 shares and
may be required to issue up to a maximum of 1,059,300 shares of common stock to
the selling shareholders without payment of additional consideration. ATG may
also be required to issue up to a maximum of 2,050,632 additional shares of
common stock to three of the selling shareholders pursuant to the terms of an
agreement with these three selling shareholders should the average closing price
of ATG's stock for the 30 trading days prior to November 1, 2001 be less than
$2.00 per share. The issuance of these additional shares, including the shares
that may be issued should ATG's stock fall below $2.00 for the 30 trading days
prior to November 1, 2001, will have a dilutive effect. ATG may further be
required to issue up to a total of 1,530,000 shares of common stock upon the
exercise of outstanding warrants and options, which on December 31, 2000 had a
weighted average exercise price of $4.03 per share. The dilution of net tangible
book value per share as of December 31, 2000 assuming all the outstanding
warrants and options are exercised is $0.15. The dilution of net tangible book
value per share as of December 31, 2000 assuming the issuance of the 3,109,932
maximum amount of additional shares that may be owing to all of the selling
shareholders is $0.28. Additionally, because of existing defaults on our credit
facility and the need to complete demonstration testing at a cost of
approximately $2 million, we will likely be required to raise significant
additional financing in the near future through the sale of equity securities,
which could have a further dilutive effect.

     We may not be able to comply with all of the environmental and other
regulatory requirements applicable to our business, which could prevent us from
operating our business according to our business plan.  If we fail to timely
obtain, or to comply with the conditions of applicable federal, state and local
governmental licenses, permits or approvals for our waste treatment facilities
and services, we could be prevented from operating our facilities and providing
services, resulting in a significant loss of revenue.   We are required to
complete our thermal demonstration testing to receive approval to become fully
operational at our processing facility for low-level mixed waste in Richland,
Washington.  We are scheduled to conduct demonstration testing in 2001.  The
cost to complete this testing is approximately $2 million.  ATG currently does
not have the funds to complete demonstration testing.  ATG must acquire the $2
million from additional equity or debt financing or from a government funded
research and development program at the Department of Energy.  Currently, the
regulatory authorities are allowing ATG to process contracted waste streams as
we prepare for demonstration testing.  The regulatory agencies allow up to 720
hours, or with an extension, up to 1440 hours, of waste stream processing prior
to demonstration testing.  After completion of these 720 hours, or 1440 hours if
an extension has been granted, ATG will no longer be able to process contracted
waste streams at our Richland facility without successful completion of
demonstration testing.  ATG is targeting three months or approximately until
June 2001, to complete the initial 720 hours, and may request an extension for
an additional 720 hours from the regulatory agencies.  To date, ATG has
processed approximately 310 hours of contracted waste streams.  Once thermal
demonstration testing of the Richland facility has commenced, if our thermal
processing systems do not meet governmental standards, this

                                       15
<PAGE>

would delay or prevent this facility from becoming operational for thermal
decontamination of mixed waste, resulting in a loss of significant revenue
potential at this facility. In addition, licenses, permits and approvals for our
existing, operational facilities and services are subject to revocation or
modification under a variety of circumstances. As our business expands and as we
introduce new technologies, we will be required to obtain additional operating
licenses, permits or approvals. We may also be required to obtain additional
operating licenses, permits or approvals if new environmental legislation or
regulations are enacted or existing legislation or regulations are amended,
reinterpreted or enforced differently than in the past. Any new governmental
requirements that raise compliance standards may require us to modify our waste
treatment technologies to conform to more stringent regulatory requirements. We
may not be able to continue to comply with all of the environmental and other
regulatory requirements applicable to our business.

  We may not be able to grow our business if we cannot develop commercially
viable technologies for treatment of wastes in a manner which is responsive to
our clients' requirements.  Our future growth is dependent upon our ability to
implement our technologies for the treatment of low-level radioactive waste,
low-level mixed waste and other waste, particularly our vitrification
technologies and technologies for treatment of ion exchange resin waste streams,
in a manner which makes them commercially viable and responsive to our clients'
requirements.  Our technologies for treatment of waste compete with other
technologies, as well as with more traditional treatment, storage and disposal
alternatives.  Our success depends on our ability to convince our clients that
our vitrification and related technologies are at least as cost-effective as
other waste treatment or waste disposal methods.  Furthermore, our ability to
comply with the terms of our contracts will affect whether clients will continue
to utilize our technologies.  For example, our contract for treatment of low-
level mixed waste with the Department of Energy's Hanford Reservation requires
us to obtain all of the required licenses, permits and approvals for, and to
build and place in operation, our treatment facility for low-level mixed waste
by November 10, 2000.  Before ATG can acquire all required licenses, permits and
approvals for the facility and place this facility in permanent operation, it
must complete demonstration testing of the facility.  Demonstration testing is
scheduled to be completed in 2001. The Department of Energy has been notified of
the schedule for completion of demonstration testing and ATG's violation of the
November 10, 2000 deadline.  To date, the Department of Energy has not notified
ATG of any corrective actions nor has ATG obtained a waiver of this violation.
On March 15, 2001, ATG received $1.9 million from the Department of Energy under
the Hanford contract.  Approximately 42% of the $1.9 million was for previously
processed waste and 58%, or $1.1 million, was for on-site receipt of waste for
future thermal processing.  If ATG fails to process this waste, it would be
obligated to return the $1.1 million.  Additionally, should ATG be unable to
process future waste received by the Department of Energy under the Hanford
contract, or otherwise fail to satisfy the terms of the Hanford contract, ATG
could suffer material losses.

  A substantial relaxation of the requirements of compliance with environmental
laws or a substantial reduction of enforcement activities by governmental
agencies would reduce the demand for our services.  In excess of 90% of our
revenues are generated as a result of requirements arising under federal and
state laws, regulations and programs related to protection of the environment.
If the requirements of compliance with environmental laws and regulations were
substantially relaxed in the future or were less vigorously enforced,
particularly those relating to the transportation, treatment, storage or
disposal of low-level radioactive waste, low-level mixed waste, or other wastes,
the demand for our services would decrease, and our revenues would be
significantly reduced.

  The cancellation or modification of our government contracts or a reduction in
government funding could significantly reduce our revenues.   Our government
contracts are generally subject to cancellation or modification at the sole
option of the government at any time, to annual funding limitations and public
sector budget constraints and, in many cases, to actual delivery orders being
released.  Any cancellation or modification of our federal government contracts
could result in a significant reduction in our revenues.  Efforts to reduce the
federal budget deficit and reduce government appropriations could adversely
affect the availability and timing of government funding for the cleanup of
Department of Energy, Department of Defense and other federal government sites
resulting in cancellations, modifications or reductions in the government
contracts for the restoration of clean-up sites with ATG, and a consequential
reduction in ATG's revenues.  The percentage of ATG's revenues attributable to
federal government contracts for the fiscal years ending 1998, 1999 and 2000 are
55%, 27%, and 30% respectively.


  We are subject to fines and penalties if we fail to comply with the
requirements of government contracts.  As a provider of services to federal and
other government agencies, we must comply with government contracting
requirements which are complex, highly technical and subject to varying
interpretations.  If we fail to comply with governmental contracting
requirements, the government could impose on us fines and penalties for failure
to follow procurement integrity and bidding rules and employing improper billing
practices or otherwise failing to follow prescribed cost accounting standards,
including disqualification from future government contract projects for a
significant period of time.  We have been, and expect to be in the

                                       16
<PAGE>

future, the subject of audits, and may in the future be subject to
investigations, by government agencies regarding our compliance with government
contracting requirements.


  Fluctuations in quarterly results due to seasonal factors may cause our
operating results to fail to meet analysts' and investors' expectations, which
could cause the price of our common stock to decline.  Our revenue is dependent
on our contract backlog and the timing and performance requirements of each
contract.  Our revenue is also affected by the timing of our clients' planned
remediation activities and need for waste treatment services, which generally
increase during the third and fourth quarters based largely on weather
conditions.  Due to this variation in demand and resulting fluctuation in
quarterly results, future quarterly operating results may not meet the
expectations of securities analysts and investors which could result in the
decline in the price of our stock.


  If we fail to manage our growth effectively, our financial, operational and
managerial  resources may be inadequate.  Our rapid growth has placed, and any
future growth may place, significant demands on our financial resources and to a
lesser extent, our operational and managerial resources which could impact the
timing and operation of waste treatment facilities. We have had and continue to
have substantial working capital deficits as a result of the strain on our
financial resources due to our rapid growth.  These working capital deficits may
impact the timing and our ability to successfully implement the operation of our
waste treatment facilities in Richland, Washington and Oak Ridge, Tennessee.
Our growth has increased significantly since 1994, when we experienced a
significant increase in the number and size of contracts awarded.  In December
1998, we acquired new business lines that contributed to increased growth in
1999. Also in 1999, we began construction of our new Richland, Washington
facility for processing of low-level mixed waste that is anticipated to
contribute to increased growth in 2001 and beyond.  In the second quarter of
fiscal 2000 at our Oak Ridge, Tennessee facility, we discontinued our Q-CEP
thermal process for decontaminating resin and are replacing it with a more cost
effective non-thermal resin decontamination process which has a greater long-
term commercial viability.


  Our facilities may be shut down due to equipment failure or failure to comply
with government regulations, which could significantly reduce our revenues.   If
any of our principal waste treatment systems were to be shut down for any
appreciable period of time, because of either equipment breakdown or regulatory
action in response to an alleged safety or other violation of the terms of the
licenses under which we operate, our revenues could be significantly reduced.
Not only could we lose revenues from shut downs, but we could also lose
potential revenues from future contracts if we could not bid for contracts
successfully because the waste treatment systems at our fixed facilities did not
perform consistently in conformance with safety and other requirements.  Our
fixed facilities are subject to frequent routine inspections by the regulatory
authorities issuing the licenses.  Our SAFGLAS(TM) system was shut down from
September 5 to September 28, 1999 due to an equipment failure, resulting in
business interruption losses and property damage of $2.7 million, of which to
date only $829,000 has been reimbursed by insurance.  We have experienced other
shutdowns of our facilities for short periods of time in the past.


  We face competition from companies with greater resources and potentially more
cost-effective waste treatment solutions.   Any increase in the number of
licensed commercial treatment facilities or disposal sites for low-level
radioactive waste or low-level mixed waste in the United States, or any decrease
in the treatment or disposal fees charged by the facilities or sites, could
reduce the competitive advantage of ATG's treatment technologies.  The market
for radioactive and hazardous waste management services is highly competitive
and we face competition in our current and planned business lines from both
established domestic companies and foreign companies attempting to introduce
European waste treatment technologies into the United States.


  Risks associated with foreign markets could impede our planned expansion into
the Pacific Rim.  A key component of our long-term business plan is to expand
our business into select Pacific Rim markets, which requires that we or our
strategic alliance partners be able to market our technologies or services
successfully in foreign markets.  However, our expansion into the Pacific Rim
region could be delayed or prevented by various risks which are inherent in
foreign operations, including general economic conditions in each country,
varying regulations applicable to our business, seasonal reductions in business
activities, fluctuations in foreign currencies or the U.S. dollar,
expropriation, nationalization, war, insurrection, terrorism and other political
risks, the overlap of different tax structures, risks of increases in taxes,
tariffs and other governmental fees and involuntary renegotiation of contracts
with foreign governments.

                                       17
<PAGE>

  A loss on one or more of our larger contracts could significantly reduce our
revenues.  If ATG is unable to accurately calculate or integrate the cost of
performing a large, multi-year contract in its contract bid and the costs are
understated significantly, ATG would likely incur a loss which would
significantly reduce our revenues.  ATG increasingly pursues large, governmental
and private sector, multi-year contracts as a method of achieving more
predictable revenue, more consistent utilization of equipment and personnel, and
greater leverage of sales and marketing costs.  The government contracts in
particular are usually awarded as a result of a competitive bidding process
requiring ATG to estimate and accurately predict its cost of performance. These
large contracts impose significant risks if actual costs are higher than those
estimated by ATG at the time of bid.


  If we were to lose any of three pending civil actions against us, including a
wrongful death action, we might become subject to a potentially large damage
award.  ATG is a defendant in a pending wrongful death civil action seeking
damages in excess of $8 million, including exemplary damages of $5 million, for
the death of an employee of a scrap metal dealer who died as a result of an
exploding piece of ordnance.  The action alleges that ATG's sub-contractor
supplied the ordnance to the scrap dealer.  A second lawsuit seeking damages of
$200,000 was filed by three other persons alleging physical injuries and
emotional distress caused by the accident.  A third lawsuit seeking damages of
$1,200,000 was filed by the property owner where the explosion occurred alleging
business interruption and property damage.  ATG is a named defendant in the
second and third actions as well.

  If we fail to maintain a Nasdaq listing for our common stock, it will become
more difficult for owners of our common stock to dispose of their shares.  Our
common stock is presently traded on the Nasdaq National Market.  If we fail to
maintain our listing for our common stock, and no other exclusion from the
definition of "penny stock" under the Exchange Act of 1934 is available, then
any broker engaging in a transaction in our securities would be required to
provide any customer with a risk disclosure document and the compensation of the
broker-dealer in the transaction and monthly account statements showing the
market values of ATG's securities held in the customer's accounts.  If brokers
become subject to the "penny stock" rules when engaging in transactions in our
securities, they may become less willing to engage in the offer and sale of our
securities.  This, in turn, may make it more difficult for owners of our common
stock to dispose of their shares.


Item 2. Properties

  ATG's principal properties, all of which are owned by ATG, are located in
Richland, Washington, Oak Ridge, Tennessee, Columbia, South Carolina and Aiken,
South Carolina, and occupy 45, 12, 16, and 30 acres, respectively.  The
facilities sited on the Richland property presently consist of 17 buildings,
covering an area of approximately 166,000 square feet, devoted to ATG's existing
operations for treatment of low-level radioactive waste and existing and future
operations for treatment of low-level mixed waste.  The facilities located on
the Oak Ridge property consist of a 40,000 square foot building devoted to resin
treatment operations for low-level radioactive waste, a 6,000 square foot office
building, and several modular office buildings.  The Columbia property includes
a 10,000 square foot building that is principally used for storage and
maintenance of equipment used in wet waste treatment.  Our Aiken property has
not been developed to date.

  In addition, ATG leases facilities in Fremont, California consisting of a
40,000 square foot corporate office building and a storage area for low-level
radioactive waste and two approximately 4,000 square foot project management
offices in Oak Ridge, Tennessee.  The Fremont facilities are leased on a month-
to-month basis and the Oak Ridge premises are occupied pursuant to leases which
expire in August 2000 with three one-year extensions available.

  Our Oak Ridge property is encumbered by a first mortgage securing our payment
of a $401,000 promissory note held by Suntrust Bank.  The Suntrust note provides
for an interest rate of 8.125% per annum, a maturity date of July 2006, monthly
payments of principal and interest of $4,900 and a balloon payment at maturity.
As of January 10, 2001, the principal balance secured by the mortgage on the Oak
Ridge property is approximately $367,000. There are no encumbrances on ATG's
Columbia or Aiken, South Carolina properties.

  We believe that our existing and planned facilities will support our
operations for the foreseeable future and are adequately covered by insurance.

Item 3. Legal Proceedings

  In June 1992, ATG entered into a contract with the U.S. Army under which ATG
acted as the prime contractor to "surface clear" expended ordnance from a firing
range at Fort Irwin, California.  In March 1997, a piece of ordnance exploded on
the premises of a scrap metal dealer in Fontana, California.  An employee of the
scrap dealer died in the accident.  Although the scrap dealer had purchased
expended ordnance and other military scrap metal from a number of military
facilities, including Fort Irwin, the scrap dealer indicated that the ordnance
which exploded was purchased from Fort Irwin.  The U.S. Army contended that a
subcontractor to ATG on the Fort Irwin contract had improperly certified
ordnance cleared from the Fort Irwin firing range as free of hazardous and
explosive material prior to the sale of ordnance to the scrap dealer.  As a
result, the U.S. Army terminated the Fort Irwin contract for default, and
demanded repayment from ATG of alleged reprocurement costs totaling $945,000.
ATG believes it fully complied with the terms of the Fort Irwin contract and
applicable laws and regulations and challenged the default termination in an
action against the U.S. Army filed in the Court of Federal Claims in July 1997.
In July 1998, the U.S. Army and ATG settled the matter.  The termination for
default was rescinded and ATG agreed to no longer bid on surface-clearing work
at active U.S. Army firing ranges.


  In connection with the accident, in March 1998 a wrongful death civil action
was filed in San Bernardino County Superior Court against the subcontractor, a
supervisory employee of the subcontractor, the owners of the premises occupied
by the scrap dealer, and ATG, seeking damages in excess of $8 million, including
exemplary damages of $5 million.  A second action was filed at the same time in
San Bernardino County Superior Court against the same defendants by three other
persons alleging physical injuries and emotional distress caused by the
accident.  The parties in the second action are seeking general damages subject
to proof estimated to be in the amount of $200,000.  A third action was also
filed in San Bernardino County Superior Court against the same defendants by the
property owner where the accident occurred asserting business interruption and
property damage caused by the accident in the amount of $1,200,000.  ATG has
tendered the defense of each of these actions to its insurance carrier, which is
presently handling the matters for ATG, and we intend to vigorously contest all
of the claims asserted in these actions.  We believe that we acted properly with
respect to the Fort Irwin contract, and that we should not be liable for the
injuries caused by the accident.  We also intend to seek indemnification from
the subcontractor for the full amount of any costs, damages and liabilities that
we may incur in connection with or as a result of these lawsuits.  The
subcontractor has advised ATG that the subcontractor's comprehensive general
liability insurance policy covers the claims asserted against the subcontractor,
and that the policy coverage limit is $7 million per occurrence.  Although we
believe that all of the claims asserted against ATG are without legal merit, the
outcome of these lawsuits is uncertain.  Any judgment of liability against ATG,
especially to the extent damages exceed or are not covered by insurance or are
not recoverable by ATG from the subcontractor, could have a material adverse
effect on our business, financial condition and results of operations.

  From time to time we are a party to litigation or administrative proceedings
relating to claims arising from our operations in the normal course of business.
Management, on the advice of counsel, believes that the ultimate resolution of
litigation currently pending against ATG is unlikely, either individually or in
the aggregate, to have a material adverse effect on our business, financial
condition or results of operations.


Item 4. Submission of Matters To a Vote of Security Holders

  No matters were submitted to a vote of shareholders during the fourth quarter
of ATG's 2000 fiscal year.

Item 7.   Management's Discussion and Analysis of Financial Condition and
          Results of Operations

  Overview

  ATG is a radioactive and hazardous waste management company that offers
comprehensive treatment solutions for low-level radioactive waste, low-level
mixed waste, and other waste generated by the U.S. Department of Defense, the
U.S. Department of Energy and commercial entities including, nuclear power
plants, medical facilities and research institutions.  ATG principally derives
its revenue from the waste treatment operations of its Fixed Facilities Group
and the on-site remediation services of its Field Engineering Group. ATG
currently focuses a significant portion of its business on SAFGLAS(TM)
vitrification of low-level radioactive waste and on its business interests in
Tennessee for treating ion exchange resins and on processing of low-level mixed
waste.  During the quarter ended June 30, 1999, ATG's permit application for its
low-level mixed waste processing facility in Richland, Washington was granted,
and in the quarter ended September 30, 1999, we began construction of this
processing facility.  ATG commenced non-thermal processing and thermal
processing of low-level mixed waste at this facility in late December 1999 and
late December 2000, respectively.

  During the quarter ended June 30, 2000, the Company announced and completed a
restructuring plan, which included a workforce reduction of approximately 110
employees at its Tennessee facilities.  The plan was primarily aimed at
improving cost efficiencies and waste treatment processes. The Company recorded
a $500,000 maintenance supply inventory write-down and a restructuring charge of
$1.9 million which included non cash charges of $800,000 for equipment taken out
of service and abandoned. During the fourth quarter of 2000, the Company
completed a review of the Tennessee fixed facilities concerning the utilization
of a modified Q-CEP thermal treatment system for the processing of specialty
niche waste streams. Due to the prohibitive cost and the unknown prospect of
success related to the proposed system modification, the Company formally
abandoned the Q-CEP thermal treatment system during the fourth quarter of 2000
and recorded a non cash asset impairment charge of $14.1 million. In addition,
the Company recorded non cash charges regarding the $1.4 million write-down of
goodwill from its acquisition of the Q-CEP assets, a $307,000 maintenance supply
inventory write-down that was charged to cost of revenue, and an $828,000 write-
down of other assets. Furthermore, a charge of $1.2 million was recorded for
processing and disposal of secondary waste associated with the shutdown of the
Q-CEP facility, of which $1.0 million remains unpaid at December 31, 2000. The
Q-CEP thermal treatment process was utilized for the treatment of ion exchange
resins from nuclear power plants. The Company is continuing the pursuit of its
non-thermal resin decontamination technology for the treatment of ion exchange
resins. See the section entitled "Comparison of Years Ended December 31, 2000
and 1999 -- Results of Operations -- Revenue and Net Income" for further
discussion.

  The U.S. government represented approximately 30%, 27%, and 55% of ATG's total
revenue for the years 2000, 1999, and 1998, respectively.  Revenue from
commercial entities, primarily nuclear power plants, industrial concerns and
medical and research institutions, has increased in recent years and represents
an increasing portion of ATG's business.  Revenue from waste treatment
processing is generally recognized upon the substantial completion of the waste
treatment process.  Field engineering services are provided under fixed price,
cost plus or unit price contracts.  Revenue from fixed price and cost plus
contracts is recognized utilizing the percentage of completion method of
accounting; revenue from unit price contracts is recognized as the units are
processed and completed.  Revenue also includes non-refundable fees received
under the terms of technology transfer agreements.

  Gross profit percentages reflect the mix of ATG's business, which varies from
time to time.  Gross profit margins are generally higher for processing
radioactive waste, while margins on nonradioactive waste projects generally are
lower. In 2000, we focused a significant portion of our business on SAFGLAS(TM)
vitrification of low-level radioactive waste, the construction completion of our
low-level mixed waste thermal processing facility, and on the restructuring of
our Tennessee business interests. During 2001, our focus for the low-level mixed
waste thermal processing facility has changed to ramping up production and the
completion of demonstration testing of the facility's processes. In 1999, we
focused a significant portion of our business on SAFGLAS(TM) vitrification of
low-level radioactive waste, on the newly acquired Tennessee business interests
and processing of low-level mixed waste. During 1998 we focused a significant
portion of our business on SAFGLAS(TM) vitrification of low-level radioactive
waste.

  ATG operates its fixed facilities under regulation of, and licenses and
permits issued by, various federal, state and local agencies.  We cannot assure
you as to the successful outcome of any pending licensing and permitting
efforts.  The licensing and permitting process is subject to regulatory
approval, time delays, community opposition and potentially stricter
governmental regulation.  Our inability to obtain licenses or permits on a
timely basis, delays or changes in facility construction programs or the
cancellation of pending projects could have a material adverse effect on our
financial condition and results of operations.

                                       22
<PAGE>

  ATG has historically relied upon the integration of proven technologies with
ATG's know-how and processes, and has not incurred significant levels of
research and development spending.  Most of the research and development
activities conducted to date have related to the design and construction of our
fixed operating facilities, particularly in connection with the SAFGLAS(TM)
system.  We anticipate that our research and development efforts will continue
to be moderate and that the costs associated with future research and
development will not be material to our results of operations.

  ATG increasingly pursues multi-year and longer term contracts as a method of
achieving more predictable revenue, more consistent utilization of equipment and
personnel, and greater leverage of sales and marketing costs.  ATG currently
focuses on large, multi-year site-specific and term contracts in the areas of
treatment of low-level radioactive waste and low-level mixed waste,
environmental restoration and D&D.  In recent years we have been awarded a
number of large government term contracts which, in most cases, require several
years to complete.  These government term contracts are subject to cancellation,
delay or modification at the sole option of the government at any time, to
annual funding limitations and public sector budget constraints and, in many
cases, to actual delivery orders being released.  These projects, which may
create an opportunity for ATG to realize margins higher than on other types of
contracts, also impose heightened risks of loss if, for example, actual costs
are higher than those estimated at the time of bid.  A loss on one or more of
these larger contracts could have a material adverse effect on our financial
condition and results of operations.  In addition, failure to obtain, or delay
in obtaining, targeted large, multi-year contracts could result in significantly
less revenue to ATG than anticipated.

Comparison of Years Ended December 31, 2000 and 1999

Results of Operations
---------------------

Revenue and Net Income/(loss).  For the year ended December 31, 2000 revenue was
$41.7 million, a decrease of $19.0 million, or 31%, from the $60.7 million
recorded for 1999. ATG recorded a net loss of $25.5 million, or $1.65 per share
for the fiscal year ended December 31, 2000, compared to net income of $5.2
million, or $0.35 per share fully diluted in 1999. The Fixed Facilities Group
generated waste processing revenue of $33.3 million, a decrease of $13.6,
compared to $46.9 million in 1999. The decrease in revenue is principally
attributable to a major shortfall in spent ion exchange resin receipts at our
facility in Oak Ridge, Tennessee. The facility processes spent ion exchange
resins from nuclear power plants, reducing the volume of waste going to final
disposal. The processed resin waste is disposed of at the Barnwell waste
disposal site in South Carolina. The operator of the Barnwell site offered
customers a very deep discount to dispose of the resins without volume
reduction, prior to the sale of the Barnwell operations in May 2000. The deep
discount program by the Barnwell disposal site was completed by the end of the
second quarter of 2000. The second quarter of fiscal 2000 was the final quarter
in which revenues are impacted by this deep discounted pricing due to South
Carolina legislation that removes the site operator's ability to set pricing and
places that authority with a multi-state appointed oversight board. During April
2000, we announced the consolidation of our Oak Ridge, Tennessee, operations and
a workforce reduction of 110 employees. The announced workforce reduction was
completed by the end of the second quarter of fiscal 2000. At the same time,
ATG's Q-CEP thermal process was being replaced by a more cost effective non-
thermal resin decontamination process. ATG's transition to the non-thermal resin
decontamination process continued during the third and fourth quarters of fiscal
2000 and is anticipated to be completed in the first half of fiscal 2001. As a
result of the restructuring, the Company during the second quarter of 2000
recorded a $500,000 maintenance supply inventory write-down and a restructuring
charge of $1.9 million related to the plant consolidation and workforce
reduction which included non cash

                                       23

charges of $800,000 for equipment taken out of service and abandoned. During the
fourth quarter of 2000, the Company completed a review of the Tennessee fixed
facilities concerning the utilization of a modified Q-CEP thermal treatment
system for the processing of specialty niche waste streams. Due to the
prohibitive cost and the unknown prospect of success related to the proposed
system modification, the Company formally abandoned the Q-CEP thermal treatment
system during the fourth quarter of 2000 and recorded a non cash asset
impairment charge of $14.1 million. In addition, the Company recorded non cash
charges regarding the $1.4 million write-down of goodwill from its acquisition
of the Q-CEP assets, a $307,000 maintenance supply inventory write-down that was
charged to cost of revenue, and an $828,000 write-down of other assets.
Furthermore, a charge of $1.2 million was recorded for processing and disposal
of secondary waste associated with the shutdown of the Q-CEP facility, of which
$1.0 million remains unpaid at December 31, 2000. In addition, revenue and gross
margin during the fourth quarter were negatively impacted by $2.8 million of
waste receipts received during the quarter that were not processed by the
Company's Richland, Washington processing facilities. The Richland facility
experienced production capacity constraints due to the inability of acquiring
the second batch processing unit (BPU) that was scheduled for installation
during the fourth quarter. The Company anticipates that the unit will be
installed during the second quarter of 2001. See section entitled "Gross Profit"
for further discussion.

  Field Engineering Group revenue was $8.4 million, a decrease of $5.4 million,
compared to $13.8 million during 1999. The decrease was due to a decrease in
contract awards as the Company emphasized its focus on its Fixed Facilities
Group.

Gross Profit.  Gross profit for 2000 was $13.1 million, a decrease of $11.2
million, or 46%, compared to $24.3 million in 1999. Gross profit as a percentage
of revenue decreased to 31% in 2000 compared to 40% in 1999. The gross profit
percentage may change from year to year and is related to the varying mixes of
business during these periods. Overall gross profit on waste processing services
was 35% in 2000 compared to 49% in 1999. The percentage decrease is principally
due to low-level radioactive waste thermal capacity constraints at the Richland,
Washington facilities which caused a number of waste streams to be processed
non-thermally resulting in increased waste disposal charges that unfavorably
impacted gross profit. Gross margin during the fourth quarter and year 2000 were
negatively impacted by waste receipts received during the quarter that were not
processed by the Company's Richland, Washington processing facilities. The
Richland facility experienced production capacity constraints due to the
inability of acquiring the second batch processing unit (BPU) that was scheduled
for installation during the fourth quarter. The Company anticipates that the
unit will be installed during the second quarter of 2001. The Company has
completed Phase II of an equipment upgrade at the Richland low-level radioactive
waste thermal facility that was anticipated to bring increased capacity online
at the end of the third quarter of fiscal 2000, but due to other equipment
maintenance issues, the overall increased capacity was not achieved during the
fourth quarter of 2000. The Phase II equipment upgrade is required for the
installation of the anticipated second BPU. The percentage decrease in 2000 was
further impacted by decreased utilization of the Tennessee fixed facilities as
discussed previously under the section entitled "Revenue and Net Income." The
fixed facilities operations generally have a larger percentage of fixed costs
versus variable costs that result in increases in utilization favorably
impacting gross profit while decreases in utilization unfavorably impact gross
profit. The overall cost of revenue for waste processing services for 2000 was
$21.6 million compared to $24.1 million for 1999. The decrease in costs is
primarily attributable to the Tennessee plant consolidation and workforce
reduction that resulted in a decrease in costs for labor, supplies, utilities,
maintenance, and waste disposal expenditures.

  Overall gross profit on field service projects was 16% in 2000 compared to 11%
in 1999. The principal reason for the percentage difference is the mix of
projects and stage of completion as many projects were utilizing fewer
subcontractor services in the current periods and the company's margin is
typically higher for contract services provided by the company as compared to
utilizing subcontractor services.  The overall cost of revenue for field service
projects for 2000 was $7.0 million compared to $12.3 million for 1999.   The
decrease in costs is primarily attributable to a reduction in the volume of
projects under contract that resulted in a decrease in costs for subcontracts,
labor, material, equipment rental, and waste disposal expenditures.

Sales, General and Administrative Expenses.  Sales, general and administrative
expenses for 2000 were $19.5 million, an increase of $4.9 million, or 34%,
compared to $14.6 million in 1999. Sales, general and administrative expenses
for 2000 were 47% of revenue compared to 24% in 1999. The increase in spending
from year to year is principally due to an increase in infrastructure at our
Richland facility and includes general and administrative expense increases
primarily attributable to labor, supplies, utilities, equipment rental, and
depreciation. The increased infrastructure is required for ATG to meet its
contractual obligations regarding the start-up of its mixed waste processing
operations. In addition, the increased 2000 expenses include bad debt expense of
$2.1 million compared to $1.4 million in 1999, and is primarily due to the
uncertainty of collection regarding a claim for additional services rendered.
The overall increase in sales, general and administrative expenses as a
percentage of revenue is principally due to decreased utilization of the
Tennessee fixed facilities as discussed previously under the section entitled
"Revenue and Net Income."

Restructuring Charge. During April 2000, we announced the consolidation of our
Oak Ridge, Tennessee, operations and a workforce reduction of 110 employees
along with replacing our Q-CEP thermal process with a more cost effective non-
thermal resin decontamination process. The announced workforce reduction was
completed by the end of the second quarter of fiscal 2000 resulting in the
company recording a $500,000 charge to cost of revenue for the write-down of the
maintenance supply inventory, and a $1.9 million restructuring charge in the
second quarter of fiscal 2000 that is comprised of plant consolidation costs of
$408,000, workforce reduction costs of $692,000, and non-cash charges of
$800,000 for equipment taken out of service. There was no remaining accrued
liability at December 31, 2000. Actual termination benefits paid were $676,000
and the actual number of terminated employees was 100 as of December 31, 2000.
Actual plant consolidation costs charged against the liability were $424,000 as
of December 31, 2000 and consist of firm fixed minimum pricing for electricity,
equipment rental contracts, and disposal site access fees that were not in use.
See the section entitled "Revenue and Net Income" for further discussion.

Plant Write-off and Abandonment Expenses.  During the fourth quarter of 2000,
the Company completed a review of the Tennessee fixed facilities concerning the
utilization of a modified Q-CEP thermal treatment system for the processing of
specialty niche waste streams. Due to the prohibitive cost and the unknown
prospect of success related to the proposed system modification, the Company
formally abandoned the Q-CEP thermal treatment system during the fourth quarter
of 2000 and recorded a non-cash asset impairment charge of $14.1 million. In
addition, the Company recorded non-cash charges regarding the $1.4 million
write-down of goodwill from its acquisition of the Q-CEP assets, a $307,000
maintenance supply inventory write-down that was charged to cost of revenue, and
an $828,000 write-down of other assets. Furthermore, a charge of $1.2 million
was recorded for processing and disposal of secondary waste associated with the
shutdown of the Q-CEP facility, of which $1.0 million remains unpaid at December
31, 2000. The Q-CEP thermal treatment process was utilized for the treatment of
ion exchange resins from nuclear power plants. The Company is continuing the
pursuit of its non-thermal resin decontamination technology for the treatment of
ion exchange resins. See the section entitled "Revenue and Net Income" for
further discussion.

Interest Income and Interest Expense.  Net interest expense was $2.8 million in
2000 (interest expense for 2000 was $3.1 million, net of capitalized interest),
compared to net interest expense of $996,000 in 1999 (interest expense for 1999
was $1.3 million, net of capitalized interest).  The increase in net interest
expense during 2000 is due to business activity that required debt financing to
support our working capital requirements. During 2000, ATG capitalized
approximately $3.4 million of interest on construction in progress in accordance
with generally accepted accounting principles, compared to $1.4 million in 1999.

Other Income.  During the second quarter of fiscal 2000, we completed the sale
and leaseback of our corporate offices in Fremont, California, resulting in a
pre-tax gain of $1.7 million. The gain is being recognized in equal increments
of $420,000 each over the next four quarters beginning in the second quarter of
fiscal 2000. We have recorded $1,261,000 of gain for 2000.

Provision for Income Taxes. In 2000 and 1999, ATG provided for income taxes at a
combined federal and state effective tax (benefit) rate of (6.9%) and 40%
respectively. The decrease in effective rate is due to the change in valuation
allowance and losses not benefited, and other items.

Comparison of Years Ended December 31, 1999 and 1998
----------------------------------------------------

  Revenue.  Revenue for 1999 was $60.7 million, an increase of $24.8 million, or
69.1%, compared to $35.9 million in 1998. The growth in revenue is derived from
ATG's Fixed Facilities Group and is principally attributable to new customers
and service offerings resulting from the acquisition of assets and related
businesses in Oak Ridge, Tennessee, and the increasing commercial utilization of
ATG's Richland, Washington facility. The newly acquired Tennessee operations
have been integrated with the Richland, Washington waste processing operations
to provide a broad range of customer service offerings. Customer waste is
directed to the processing location capable of providing the most efficient and
economical treatment. The Fixed Facilities Group generated waste processing
revenue of $46.9 million during 1999, an increase of $28.0 million, compared to
$18.9 million in 1998.

  Our revenue for the last two quarters of 1999 was impacted by an unscheduled
shutdown of the SAFGLAS(TM) thermal treatment system and the related bulk-
processing unit (BPU) at our facilities in Richland, Washington. Both the glass
melter and BPU units ceased operation on September 5, 1999, due to the failure
of a SAFGLAS(TM) glass drain. Both the SAFGLAS(TM) thermal treatment system and
BPU returned to operational status on September 28, 1999. The required slow
startup of the thermal treatment systems during October had a further negative
impact on revenue.

  Field Engineering Group revenue during 1999 was $13.8 million, a decrease of
$3.2 million, compared to $17.0 million in 1998. The revenue decrease was due to
a decrease in new contract awards and weather related delays.

                                       25
<PAGE>

  Gross Profit.  Gross profit for 1999 was $24.3 million, an increase of $8.2
million, or 50.9%, compared to $16.1 million for 1998.  Gross profit as a
percentage of revenue decreased to 40.1% in 1999 compared to 44.8% in 1998.
Gross profit percentages reflect the various mixes of ATG's business services
from time to time. The Fixed Facilities Group experienced a decline in gross
margin during 1999, compared to 1998, due principally to delayed customer
shipments of low-level radioactive waste, the unscheduled SAFGLAS(TM) outage in
September, competitive pricing pressures, and a delay in shipments of non-
thermal low-level mixed waste.  The Field Engineering Group also experienced a
decline in gross margin during 1999, compared to 1998, due to its 1999 project
mix being weighted towards fixed fee and fixed unit price contracts.

  Sales, General and Administrative Expenses.  Sales, general and administrative
expenses (including stock-based compensation expense) were $14.7 million for
1999, an increase of $6.7 million, or 83.8%, compared to $8.0 million in 1998.
Sales, general and administrative expenses were 24.2% of revenue in 1999,
compared to 22.2% of revenue in 1998. The increases in spending from year to
year reflect the growth in ATG's operations, addition of sales and
administrative personnel related to the acquisition of the Tennessee operations
and the increased costs of being a public company. In addition, the increased
1999 spending also includes the recording of a $1.4 million charge to bad debt
expense related primarily to slow payment of government contracts completed
prior to 1999.  ATG is maintaining its collection efforts. Sales, general and
administrative expenses include indirect engineering and operating overhead,
depreciation and amortization, and expenses to support the domestic sales and
marketing activities and the financial and administrative functions.

  Interest Income and Interest Expense.  Net interest expense was $996,000 in
1999 (interest expense for 1999 was $1.3 million, net of capitalized interest),
compared to net interest income of $188,000 in 1998 (interest expense for 1998
was $15,000, net of capitalized interest).  The increase in net interest expense
during 1999 is due to our increased business activity that required debt
financing to support our working capital requirements. Interest expense was nil
in 1998 as the result of ATG capitalizing approximately $1.0 million of interest
on construction in progress in accordance with generally accepted accounting
principles. During 1999, ATG capitalized $1.4 million of interest on
construction in progress.

  Provision for Income Taxes.  In 1999 and 1998, ATG provided for income taxes
at a combined federal and state effective tax rate of 40% and 38% respectively.
The increase in effective rate during 1999, compared to 1998, is due to the
estimated increase in state income taxes, non-deductible and other items.

Liquidity and Capital Resources
-------------------------------

  Total cash and cash equivalents were $351,000 at December 31, 2000, a decrease
of $2.4 million from December 31, 1999. The working capital deficit of the
Company was approximately $35.2 million at December 31, 2000, a decrease of
$38.5 million from working capital of $3.3 million at December 31, 1999. The
working capital calculation excludes restricted cash of $16.0 million and
accounts payable of $3.5 million at December 31, 1999, that are exclusively for
the construction of our low-level mixed waste facility. The decrease in working
capital is partially due to the reclassification of $23.75 million of long-term
debt to short-term borrowing pursuant to the lender's credit facility
forbearance and consent agreement with the Company, dated June 1, 2000, the
collection of accounts receivable that were utilized to fund operations, and the
increase in accounts payable from the completion of the low-level mixed waste
facility in Richland, Washington. See discussion of our credit facility below.

  During June 2000, we completed a $5.5 million private placement of 2.75
million shares of common stock at $2 per share. On June 30, 2000, we completed
the first tranche of the private placement by issuing 2.62 million shares of
common stock for an aggregate price of $5.24 million. On July 7, 2000, we
completed the second tranche of the private placement, issuing 130,000 shares of
common stock for an aggregate purchase price of $260,000. In connection with the
private placement, the company issued warrants to purchase a total of 192,500
shares of common stock. The warrants expire on June 30, 2005 and are exercisable
at a price of $2.75 per share, subject to adjustment for:

  .   amendments to ATG's Articles of Incorporation which change the rights,
      privileges, restrictions or conditions of ATG's common stock or effect a
      division of ATG's common stock;

  .   a division of our common stock into a greater number of shares of our
      common stock or a declaration of a dividend or the making of any other
      distribution upon the common stock payable in shares of common stock; or

  .   a capital reorganization or classification of the capital stock of ATG, or
      any consolidation or merger of ATG with another corporation or entity, or
      the sale of all or substantially all of ATG's assets to another
      corporation or entity wherein holders of ATG common stock shall be
      entitled to receive stocks, securities, other evidence of equity ownership
      or assets with respect to or in exchange for shares of ATG common stock.

                                       26
<PAGE>

ATG received a total of approximately $5.1 million in net proceeds from this
private placement.

  Significant outlays of cash have been needed to acquire property and equipment
and to secure or expand regulatory licenses, permits and approvals, primarily
for improvements to our low-level radioactive waste facility and construction of
the low-level mixed waste facility in Richland, Washington and for improvements
to and the restructuring of our fixed facilities in Oak Ridge, Tennessee.
Property and equipment acquisitions totaled $29.2 million, $28.2 million and
$5.0 million for the years ended December 31, 2000, 1999, and 1998. In addition,
we used approximately $3.0 million of cash during 1999 regarding the acquisition
of assets for the Oak Ridge facility. See Note 3 to the company's Consolidated
Financial Statements for the periods ended December 31, 2000 and 1999, entitled
"Acquisition," for further details. ATG also used approximately $3.5 million of
cash during 2000 relating to the waste acquisition accrued liability associated
with its 1999 purchase accounting for its acquisition of the assets of Molten
Metals Technology.

  In November 1999, ATG completed an agreement with a consortium of banks for a
credit facility in the amount of $45 million. The credit facility includes a
letter of credit in support of tax-exempt Solid Waste Revenue Bonds in the
aggregate face amount of $26.5 million. The bonds were issued during November
1999, and bear interest at a floating rate (5.10% at December 31, 2000), based
upon prevailing market conditions, which is redetermined every seven days. The
bonds are due October 31, 2014 and may be prepaid at any time without penalty.
The proceeds are to be applied exclusively for the construction of low-level
mixed waste facility in Richland, Washington. The credit facility also includes
a five year revolving working capital line of credit, due October 2004, in the
amount of $18 million, including a letter of credit facility of $5 million.
Borrowings, when made, bear a variable interest rate based on financial ratio
criteria. The credit facility is collateralized by accounts receivable,
inventory and equipment.

  The credit facility agreement requires ATG to comply with a number of
covenants, including capital asset acquisition limits, limits on additional
debt, minimum levels of tangible net worth, dividend payment restrictions and
maintenance of financial ratios.  At December 31, 1999, ATG was in violation of
some of these financial ratio covenants. ATG obtained a permanent waiver,
subsequent to year-end, in respect of these violations as of December 31, 1999.
In connection with the waiver, the banks agreed to revise and lower some of the
financial ratio covenants that ATG failed to meet as of December 31, 1999, and
substitute new covenants, for which ATG was in compliance for the original
violated covenants and revise and lower some of the financial covenants for each
of the quarterly periods in the year ended December 31, 2000, and increase the
borrowings available to ATG by $6 million, for a total of $24 million, through
June 30, 2000. The borrowing limit subsequent to June 30, 2000 is $18 million.
In addition, the interest rate applied to the working capital facility was
revised.

  At March 31, 2000 ATG was in violation of the revised financial ratios under
the credit facility. Pursuant to a forbearance and consent agreement dated as of
June 1, 2000, the lenders agreed to forbear in the exercise of any of their
rights or remedies with respect to March 31, 2000 covenant defaults through June
30, 2000.

  At June 30, 2000 ATG was in violation of the revised financial ratios under
the credit facility.  Furthermore, at June 30, 2000, ATG failed to make a
required payment of principal in the approximate amount of $5,750,000 as a
mandatory paydown under the revolving credit facility, so as to bring total
borrowings under that facility to the $18 million limit.  ATG currently has
borrowings of $23.75 million and is paying interest at the default rate of
12.75%.

  ATG has requested that the banks grant a forbearance in respect of the
violations described above beyond June 30, 2000.  As one of the conditions to
granting a forbearance, the banks requested that ATG deposit into a segregated
account the amount of $1,500,000 to finance the completion and demonstration
testing of the company's new low level mixed waste facility in Richland,
Washington which is currently under construction.  Consequently, on August 11,
2000, ATG obtained a short-term loan in the amount of $1,500,000 bearing a
maturity date of October 5, 2000 from an individual lender.  The loan bears
interest at a rate of 12% per annum.  ATG was unable to repay the loan on its
stated maturity date and subsequently obtained an extension until December 15,
2000.    ATG is seeking to obtain an extension to the December 15, 2000 due
date, but to date has not obtained this extension.  ATG anticipates that it will
need to obtain additional financing or obtain another extension on the due date
in order to repay the loan.

  ATG failed to make interest payments in the last quarter of 2000 of amounts
totaling $765,443 and failed to make interest payments in the first quarter of
2001 of amounts totaling $715,634. In addition, ATG failed to make fee payments
of $60,035 in the last quarter of 2000 and failed to make a letter of credit fee
payment in the first quarter of 2001 in the amount of $218,640.

                                       27
<PAGE>

  ATG will not be able, without obtaining concessions from the banks or new
financing, to make the mandatory principal paydown of approximately $5,750,000,
$765,443 interest owing for the last quarter of 2000, $715,634 interest owing
for the first quarter of 2001, $60,035 fee owing for the last quarter of 2000,
and the $218,640 letter of credit fee owing for the first quarter of 2001 under
the credit facility, or to comply with the current financial covenants set forth
in the agreements governing the credit facility.

  As of April 5, 2001, the banks have not granted a forbearance in respect of
the violations of the credit agreement beyond June 30, 2000.  The lenders could
elect at any time to enforce their rights and remedies under the credit
agreement.  The banks' remedies could include a demand for repayment of all
outstanding loans, which raises substantial doubt about the ability of the
company to continue as a going concern if it cannot obtain additional cash to
repay or restructure the debt.  ATG is continuing to negotiate with the lenders
to modify the financial covenants and the time frame for the mandatory paydown.
ATG is seeking alternative forms of financing in order to make the mandatory
paydown.  ATG is also reviewing its business plan with its financial advisors
and lenders with the objective of seeking appropriate accommodations and to
ascertain what actions can be taken to enhance liquidity and thereby generate
cash to assist in paying the company's debt service.  ATG is also evaluating
potential changes in its capital structure and additional financial resources.
If ATG is unable to service its indebtedness, we may be required to alter our
business plans, seek to restructure or refinance our indebtedness or seek
additional equity capital.

  We will not have sufficient cash generated from operations to meet our working
capital requirements for the next twelve months unless we are able to negotiate
accommodations from our lenders or refinance our indebtedness.

  The accompanying financial statements have been prepared assuming that ATG
will continue as a going concern. As discussed in Note 9 and 18 to the financial
statements, ATG is in default of certain provisions related to our credit
facility. The default allows the bank consortium to demand repayment of the
outstanding balance. ATG has incurred a substantial operating loss during 2000
and has negative working capital of $35.2 million at December 31, 2000. ATG
requires additional capital to meet its obligations and accomplish our business
plan, which raises substantial doubt about ATG's ability to continue as a going
concern. The accompanying financial statements do not include any adjustments
that might result from the outcome of this uncertainty.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

  We considered the provisions of Financial Reporting Release No. 48,
"Disclosure about Accounting Policies for Derivative Financial Instruments and
Derivative Commodity Instruments, and Disclosure of Qualitative Information
about Market Risk Inherent in Derivative Financial Instruments, Other Financial
Instruments and Derivative Commodity Instruments".  We had no derivative
financial or commodity instruments at December 31, 2000.  Our long term credit
facility provides for interest at a floating or variable rate that may fluctuate
over time based on changes, as applicable, in the prevailing market conditions
or in designated financial ratios applicable ATG pursuant to its terms. Our
short term line of credit has an interest rate based on the bank's reference
rate that may fluctuate over time based on changes in the prevailing market
conditions. We are subject to interest

                                       28

rate risk, and could be subjected to increased interest payments if market
interest rates fluctuate. An effective increase or decrease of 10% in these
interest rates would have a material adverse effect on our results of
operations.

The Board of Directors and Committees

  The directors serve until the next annual meeting of shareholders or until
successors are elected and qualified.  ATG's executive officers are appointed by
and serve at the discretion of the Board.  There are currently six members on
the Board.  One position on the Board is currently vacant, and the company is
continuing its search for an additional member.   The Board of Directors has two
committees, the Audit Committee and the Compensation Committee.

Compensation of Directors

  Each non-employee director receives a cash fee of $2,000 per Board meeting
attended (but not including conference calls) and an additional $2,000 per Board
Committee meeting attended, if the committee meeting is held on a day different
from that of a Board meeting.  Each non-employee Board member, upon appointment
or election to the Board and pursuant to the company's 1998 Non-Employee
Directors' Stock Option Plan, as described below, receives an automatic option
grant to purchase 20,000 shares of common stock at an option exercise price
equal to 100% of the market price of the common stock on the date of grant, with
each option having a maximum term of ten (10) years and becoming immediately
exercisable as to 5,000 of the option shares upon the date of grant.  The
balance of the option shares vest at 5,000 shares each on the succeeding three
anniversaries of the grant date.

Non-Employee Directors' Stock Option Plan

  In February 1998, the Board adopted the 1998 Non-Employee Directors' Stock
Option Plan to provide for the automatic grant of options to purchase shares of
Common Stock to non-employee directors of ATG. The plan is administered by the
Board. To date, 120,000 options have been granted under the plan.

  The maximum number of shares of common stock that may be issued pursuant to
options granted under the plan is 200,000. Pursuant to the terms of the plan,
each person serving as a director of ATG who is not an employee of ATG shall
automatically be granted an option to purchase 20,000 shares of common stock
upon the date the person first becomes a non-employee director, with 5,000 of
his or her shares vesting immediately and the balance vesting in three equal
installments on the three succeeding anniversaries of the grant date.

  The exercise price of the options granted under the plan must equal or exceed
the fair market value of ATG's common stock on the date of grant. No option
granted under the plan may be exercised after the expiration of ten years from
the date it was granted. Options granted under the plan are generally non-
transferable except by will or by the laws of descent and distribution.

                                       31
<PAGE>

The plan will terminate at the discretion of the Board; provided, however, that
in no event will the term of the plan extend beyond the tenth anniversary of its
adoption by the Board.

  In the event of changes of control of ATG, as defined in the plan, any
outstanding options will automatically become fully vested and will terminate if
not exercised prior to the change of control.

Audit Committee

  The Audit Committee of the Board is currently composed of Messrs. Doubleday,
Chan, Sebastian and Thomas and is chaired by Mr. Chan.  Prior to the annual
shareholders' meeting of ATG held on July 14, 2000, the Audit Committee of the
Board was composed of Messrs. Gjelde, Doubleday and Kadak and was chaired by Mr.
Gjelde.  The Audit Committee met two (2) times in fiscal year 2000. The
functions performed by the Audit Committee include making recommendations to the
Board of Directors regarding the selection of independent accountants to serve
the company for the ensuing year and reviewing with the independent accountants
and management the general scope and results of the company's annual audit, the
fees charged by the independent accountants and other matters relating to
internal control systems.  In addition, the Audit Committee is responsible for
reviewing and monitoring the performance of non-audit services by the company's
auditors and for recommending the engagement or discharge of the company's
independent accountants.

Compensation Committee

  The Compensation Committee of the Board is currently composed of Messrs.
Doubleday, Chan, Sebastian and Thomas and is chaired by Mr. Doubleday.  Prior to
the annual shareholders' meeting of the company held on July 14, 2000, the
Compensation Committee of the Board was composed of Messrs. Kadak, Doubleday and
Gjelde, and was chaired by Mr. Kadak.  All members of this Committee are non-
employee directors.  The responsibilities of the Compensation Committee include
establishing the compensation of the Chief Executive Officer, reviewing and
approving executive compensation policies and practices, reviewing salaries and
bonuses for key executive officers of the company and administering the
company's stock option plans. The Compensation Committee met two (2) times in
fiscal year 2000.

Section 16(a) Beneficial Ownership Reporting Compliance

  Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
ATG's directors and executive officers, and persons who own more than 10% of
ATG's  common stock, to file reports of ownership on Form 3 and changes in
ownership on Form 4 or 5 with the Securities and Exchange Commission and the
NASDAQ national market.   Such directors, executive officers and 10%
stockholders are also required by SEC rules to furnish ATG with copies of all
Section 16(a) forms they file.  Based solely upon its review of copies of such
forms received by it, or on written representations from certain reporting
persons that no other filings were required for such persons, ATG believes that,
during the year ended December 31, 2000, all Section 16(a) filing requirements
applicable to its directors, executive officers and 10% stockholders were
complied with except that the 20,000 options automatically granted to the
directors of ATG upon their election on July 14, 2000 at the annual
shareholders' meeting of the company, consisting of David Chan, David Sebastian
and James Thomas, were inadvertently reported on a Form 3 instead of a Form 4 or
Form 5, and no Form 4 or Form 5 has yet been filed to report those option
grants.

Item 11.  Executive Compensation

The following table discloses compensation received by ATG's Chief Executive
Officer and the four (4) remaining most highly paid executive officers who
received total compensation in excess of $100,000 for the previous years ended
December 31, 2000, 1999 and 1998.

Employment Agreements

  In October 2000, ATG entered into an Employment Agreement with Vik Mani for
Mr. Mani's employment as Chief Operating Officer to the company.  Under the
terms of this Agreement, which has a term of thirty-six (36) months, upon
execution by Mr. Mani and resignation from his prior employer, Mr. Mani received
a signing bonus of $560,000.   For the first twelve (12) months of employment,
Mr. Mani receives a base salary of $225,000 and a cash bonus of $100,000.  For
the second year of employment, Mr. Mani receives a base salary of $225,000 and a
cash bonus of $75,000.  In the second year Mr. Mani may also receive additional
amounts not to exceed $100,000 as performance bonuses if certain performance
criteria are met.  For the third year of employment, Mr. Mani receives a base
salary of $150,000 until certain performance criteria are met.  If the
performance criteria are met, Mr. Mani's salary is increased to a rate of
$240,000 annually and Mr. Mani is entitled to a cash bonus of up to $110,000.
The Employment Agreement requires Mr. Mani to pay back certain penalty amounts
should he resign prior to the expiration of the term of the Agreement.  The
penalty amounts are $162,000 for the first year, $108,000 for the second year
and $50,000 for the third year.

  The Employment Agreement provides that Mr. Mani would be granted an option to
purchase 75,000 shares of ATG's stock at the market price of the stock at the
beginning of the employment term with vesting over thirty-six months.  Mr. Mani
is entitled to options to purchase an additional 90,000 shares of stock at the
stock price as of December 31, 2001 if certain performance criteria are met,
with such options vesting over thirty-six months.  Mr. Mani will be entitled to
options to purchase an additional 100,000 shares at the stock price as of
December 31, 2001, vesting over thirty-six months, if the stock of ATG sells
publicly for $20 or more for three consecutive months.  The Agreement provides
that all stock options vest immediately in the case of Mr. Mani's death,
disability, termination by ATG, or resignation for certain reasons or a change
in control of ATG.    As of December 31, 2000, the Board of Directors had not
approved a grant of any stock options to Mr. Mani.

  The Employment Agreement provides further for Mr. Mani to be provided, at ATG
expense, ATG's corporate house in Richland, Washington for use as Mr. Mani's
residence.  The Agreement provides for the company's payment of an auto loan of
up to $30,000 for Mr. Mani.  The Agreement provides for Mr. Mani's participation
in the company's standard benefit package for insurance, 401K plan, etc.  The
Agreement also provides that if Mr. Mani resigns due to a change in control of
ATG, Mr. Mani's stock options granted prior to the date of resignation shall be
vested, and his resignation shall not cause any of the penalty amounts otherwise
due upon resignation to be payable.  The Agreement further provides, in the case
of a resignation due to change in control of ATG, that the company will pay Mr.
Mani a severance amount equal to the twelve month salary amount for the twelve
month period in which the resignation occurred and will pay Mr. Mani's remaining
auto loan balance, his cash bonus for the year in which the resignation
occurred, his relocation costs and will provide for a continuation of medical
benefits at ATG's expense for twelve months after the effective date of the
resignation.

Employee Benefit Plans

Stock Ownership Incentive Plan

  In February 1998, the Board adopted the 1998 Stock Ownership Incentive Plan.
The plan authorizes the award of stock options, shares of restricted stock and
performance units (which may be paid in cash or shares of common stock). The
plan reserves for issuance an aggregate of 1,000,000 shares of common stock, no
more than 250,000 shares of which may be issued in the form of shares of
restricted stock. The plan is intended to advance the interests of ATG by
encouraging the employees who contribute to ATG's long-term success and
development to acquire and retain an ownership interest in the company.

  The plan is administered by the Board. The Board selects employees to receive
awards under the plan and determine the terms, conditions and limitations
applicable to each award. Each award will be evidenced by a grant letter from
the Board to the recipient setting forth the terms and conditions of the award.
The plan will terminate at the discretion of the Board; provided, however, that
in no event will the term of the Incentive Plan extend beyond the tenth
anniversary of its adoption by the Board.

  Stock options granted pursuant to the plan may either be incentive stock
options ("ISOs") intended to qualify under Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"), or stock options not intended to so
qualify. Each stock option awarded under the plan must have an exercise price
equal to at least 100% of the fair market value of the common stock on the date
of grant, and ISOs granted to any employee possessing more than 10% of the
combined voting power of all classes of stock of ATG must have an exercise price
equal to at least 110% of the fair market value.  Optionees may exercise options
under the plan by paying cash, by tendering shares of common stock, by using a
cashless exercise procedure provided for in the plan, or by a combination
thereof, as permitted by the Board. Options vest in equal installments over a
five year period and, upon a change of control of ATG, as defined in the plan,
any outstanding options become fully vested and immediately exercisable.
Options granted under the plan are generally non-transferable except by will or
by the laws of descent and distribution. No option granted under the plan may be
exercised after the expiration of ten years from the date it was granted.

Employee Stock Purchase Plan

  In February 1998, the Board approved the ATG Employee Stock Purchase Plan
covering an aggregate of 200,000 shares of common stock. The plan is intended to
qualify as an employee stock purchase plan within the meaning of Section 423 of
the Code. Under the plan, the Board may authorize participation by eligible
employees of the company, including officers, in periodic offerings following
the adoption of the Purchase Plan. The offering period for any offering will be
determined by the Board, but in no event will be more than 27 months.

  Employees are eligible to participate if they are employed by ATG or an
affiliate of ATG designated by the Board. Employees who participate in an
offering may have up to 15% of their earnings (provided that this amount does
not exceed $25,000 in value per calendar year) withheld pursuant to the plan and
applied, on specified dates determined by the Board, to the purchase of shares
of common stock. The price of common stock purchased under the plan will be
equal to 85% of the lower of the fair market value of the common stock on the
commencement date of each offering period or the relevant purchase date.
Employees may end their participation in the offering at any time during the
offering period, and participation ends automatically on termination of
employment with ATG.

  In the event of changes of control of ATG, as defined in the plan, the Board
has discretion to provide that each right to purchase common stock will be
assumed or an equivalent right substituted by the successor corporation, or the
Board may shorten the offering period and provide for all sums collected by
payroll deductions to be applied to purchase stock immediately prior to the
change in control. The plan will terminate at the discretion of the Board.

401(k) Plan

  In 1995, ATG established a 401(k) tax-qualified employee savings and
retirement plan covering all of its employees. Pursuant to the 401(k) plan,
employees may elect to reduce their current compensation by up to the lower of
15% of their compensation or the annual limit prescribed by statute ($9,500 in
1997) and contribute the amount of the reduction to the 401(k) plan. The 401(k)
plan allows for matching contributions to the 401(k) Plan by ATG, which matching
and the amount of this matching to be determined at the sole discretion of the
Board.  During 2000 and 1999, ATG contributed $53,000 and $61,000 in matching
funds through the issuance of shares of its common stock to the 401(k) plan.
The trustee under the 401(k) plan, at the direction of each participant, invests
the assets of the 401(k) plan in numerous investment options.  The 401(k) plan
is intended to qualify under Section 401 of the Code so that contributions by
employees to the 401(k) plan, and income earned on plan contributions, are not
taxable until withdrawn, and so that the contributions by employees will be
deductible by ATG when made.

Item 13.  Certain Relationships and Related Transactions

  The following is a summary of significant transactions to which ATG was or is
a party and in which executive officers, directors or shareholders who own more
than 5% of the shares of ATG had or have a direct or indirect material interest.

  From 1992 to 1997, Doreen M. Chiu, ATG's Chairman of the Board and Chief
Executive Officer, extended a series of loans to ATG, each of which was
repayable in full upon demand.  The loans, which were unsecured, bore interest
at an annual rate of 10%, payable concurrently with principal.  The outstanding
principal balance of the loans, including accrued interest, at December 31, 1997
was $1,280,180.  These loans were repaid in full in May 1998.

                                       37
<PAGE>

  Doreen M. Chiu and Frank Y. Chiu, the Executive Vice-President and a director
of ATG, have each guaranteed the obligations of ATG under the following:


  .   two promissory notes issued June 1997 and May 1999 in the principal
      amounts of $2,069,604 and $1,996,075 held by Safeco Credit Company, Inc.;

  .   a commercial lease agreement between ATG and U.S. Bancorp issued June 1997
      with an aggregate rental amount of $103,341; and

  .   a note issued August 11, 2000 in the amount of $1,500,000 payable to Jack
      Chau.

  In connection with the issuance of bonds, undertakings and other instruments
of guarantee in favor of ATG, Doreen M. Chiu and Frank Y. Chiu have each
executed the following:


  .   a blanket indemnity agreement issued June 1996 in favor of ACSTAR
      Insurance Company, indemnifying ACSTAR against any losses that ACSTAR may
      incur in connection with the issuance of any of these bonds, undertakings
      or other instruments of guarantee;

  .   a blanket Continuing Agreement of Indemnity-Contractor's Form for the
      benefit of Reliance Insurance Company, United Pacific Insurance, Reliance
      National Indemnity Company and Reliance Surety Company, issued March 1998
      indemnifying these entities against any losses that these entities may
      incur in connection with the issuance of any of these bonds, undertakings
      or other instruments of guarantee.

  As of December 31, 2000, the potential aggregate liability of Mr. and Mrs.
Chiu under the blanket indemnities was approximately $35,500.

  In June 1998, ATG entered into a contract to provide engineering, remediation
and construction services to Mission Ranch Center, a California limited
partnership.  Doreen M. Chiu and Frank Y. Chiu are general partners and own a
50% partnership interest in Mission Ranch.  ATG reported revenues of $2,779,000
and costs of $2,423,000 related to services provided under this contract in
2000.  ATG reported revenues of $1,403,000 and costs of $1,354,000 related to
services provided under this contract in 1999.  ATG reported revenues of
$785,000 and costs of $432,000 related to services provided under this contract
in 1998.  The total project contract value is approximately $4,697,000 and is
expected to be completed in early 2001.

  On October 5, 2000 and October 13, 2000 Mr. and Mrs. Chiu advanced $307,500
and $252,500, respectively to ATG.  Mrs. Chui also advanced $445,000 in various
months of 2000 for expenses of ATG.

  On June 30, 2000, ATG sold a total of 2,000,000 shares of common stock for
$2.00 per share in a private placement to Special Situations Fund III, L.P.,
Special Situations Cayman Fund, L.P. and Special Situations Private Equity Fund,
L.P., each of which is a selling shareholder in this prospectus.  The stock
purchase agreements require ATG to file a registration statement with the SEC to
register the resale of the private placement shares.  If the registration
statement is not filed within 45 days and effective within 120 days, then the
stock purchase agreements require ATG to issue additional shares of common stock
to the funds in amounts calculated based on the length of the delays, but not to
exceed 36% of the number of private placement shares.  Because the registration
statement was filed after more than 45 days and was not effective within 120
days, the funds became entitled to receive additional shares of common stock as
provided in the stock purchase agreements.

     However, on December 29, 2000, ATG entered into a settlement agreement with
the funds whereby ATG and the funds settled disputes about their respective
rights and obligations under the stock purchase agreements.  The funds agreed to
waive their rights under the stock purchase agreements to receive additional
shares of common stock and other alleged rights in exchange for a one-time
right, exercisable by written notice to ATG on or before November 15, 2001, to
have the price of their private placement shares reset.  The reset right will be
based on the average closing price of ATG common stock for the 30 trading days
prior to November 1, 2001 if less than $2.00 per share, except that the price
may not be reset to a price that is lower than the average closing price of ATG
common stock for the 15 trading days prior to December 27, 2000.  Under the
settlement agreement, ATG is not required to honor any reset notice from the
funds if, within ten business days after receiving the notice, ATG repurchases
all of the funds' private placement shares for $2.00 per share.  The settlement
agreement further provides that if ATG's registration statement is not effective
by March 31, 2001, then the funds' rights to receive additional shares under the
stock purchase agreements will automatically be reinstated.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and the stockholders
of ATG Inc.:

     In our opinion, the consolidated financial statements listed in the index
appearing under Item 14(a)(1) on Page 39 present fairly, in all material
respects, the financial position of ATG Inc. and its subsidiaries at December
31, 2000 and 1999, and the results of their operations and their cash flows for
each of the three years in the period ended December 31, 2000 in conformity with
accounting principles generally accepted in the United States of America. In
addition, in our opinion, the financial statement schedule listed in the index
appearing under Item 14(a)(2) on Page 39 presents fairly, in all material
respects, the information set forth therein when read in conjunction with the
related consolidated financial statements. These financial statements and
financial statement schedule are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements and
financial statement schedule based on our audits. We conducted our audits of
these statements in accordance with auditing standards generally accepted in the
United States of America, which 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, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Notes 1 and 18 to the
financial statements, the Company has incurred operating losses, is in default
of certain provisions of the Company's credit facility, and requires additional
capital to meet its obligations and accomplish the Company's business plan,
which raises substantial doubt about its ability to continue as a going concern.
Management's plans concerning these matters are also discussed in Notes 1 and
18. The financial statements do not include any adjustments that might result
from the outcome of this uncertainty.

                                   ATC INC.
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
           (all dollar amounts in thousands unless otherwise noted,
                            except per share data)

1. Formation and Business of the Company

     ATG Inc. (the "Company" or "ATG") provides technical personnel and
specialized services and products primarily to the U.S. government and the
nuclear power industry. Services principally consist of compaction, reduction,
decontamination, vitrification and disposal of low-level nuclear waste,
dewatering and thermal treatment of ion exchange resins, decontamination,
stabilization and volume reduction of low-level mixed waste, site remediation
and construction projects.

     Hazardous waste is waste that is classified as hazardous under U.S.
governmental acts. The list of "hazardous substances" covered by these laws is
extensive and includes a large number of chemicals, metals, pesticides,
biological agents, toxic pollutants and other substances. ATG is not engaged in
the large but highly competitive hazardous waste treatment market other than
through the environmental restoration services provided by its Field Engineering
Group. Historically, ATG has processed a broad range of hazardous substances at
client sites during the execution of environmental restoration projects.

     In May 1998, the Company completed an initial public offering of 1,900,000
shares of common stock and in June 1998, sold an additional 285,000 shares of
common stock.  Total proceeds to the Company, net of underwriting discounts and
other direct expenses, were approximately $15.7 million.

     During June and July 2000, ATG completed a $5.5 million private placement
of 2.75 million shares of common stock at $2 per share. In addition, the Company
issued 192,500 warrants at an exercise price of $2.75 per share in connection
with the private placement. ATG received a total of approximately $5.1 million
in net proceeds from this private placement.

     Under agreements with the shareholders purchasing shares in June 2000, ATG
is currently required to issue a total of 578,875 shares and may be required to
issue up to a maximum of 1,059,300 shares of common stock to the selling
shareholders without payment of additional consideration. ATG may also be
required to issue up to a maximum of 2,050,632 additional shares of common stock
to three of the selling shareholders pursuant to the terms of an agreement with
these three selling shareholders should the average closing price of ATG's stock
for the 30 trading days prior to November 1, 2001 be less than $2.00 per share.
The issuance of these additional shares including the shares that may be issued
should ATG's stock fall below $2.00 for the 30 trading days prior to November 1,
2001 will have a dilutive effect. ATG may further be required to issue up to a
total of 1,530,000 shares of common stock upon the exercise of outstanding
warrants and options, which on December 31, 2000 had a weighted average exercise
price of $4.03 per share.

     Restatement of 1998 Financial Results: Subsequent to filing a registration
statement on Form S-1 with the Securities and Exchange Commission ("SEC") on
September 20, 2000 and amendments thereto, which included the audited financial
statements of ATG Inc. (the "Company") for the years ended December 31, 1999,
1998 and 1997, the Company became aware that the revision of its purchase price
in 1999 for the business acquired effective December 1, 1998 was not in
accordance with generally accepted accounting principles. Based on the
information available to the Company at the time of the purchase price
allocation, the Company misapplied the fact situation surrounding the allocation
of the purchase price to a certain acquired liability, "pre acquisition waste."
The revisions had no impact on the statement of operations reported for any
period within the three year period ended December 31, 1999. The Company will be
filing a Form 10-K/A for the year ended December 31, 1999 to reflect the
restatement.

Liquidity and Going Concern Considerations

     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 9 and 18 to the
financial statements, the Company is in default of certain provisions related to
the Company's credit facility. The default allows the bank consortium to demand
repayment of the outstanding balance. The Company has incurred a substantial
operating loss during 2000 and has negative working capital of $35,239 at
December 31, 2000. The Company requires additional capital to meet its
obligations and accomplish the Company's business plan, which raises substantial
doubt about its ability to continue as a going concern. Management's plans are
discussed in Note 18. The accompanying financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

2. Summary of Significant Accounting Policies

  Basis of Presentation

     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries, ATG Richland Corporation ("ATG Richland") and
ATG Nuclear Services LLC ("ATG Nuclear") and its subsidiary, ATG Catalytics LLC
("ATG Catalytics"). All significant intercompany balances and transactions have
been eliminated.

  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 amounts reported in the consolidated financial
statements and accompanying disclosures. These estimates include assessing the
collectibility of accounts receivable, contracts in process and the
recoverability of self-constructed assets and provisions for contingencies.
Actual results could materially differ from the Company's estimates.

  Revenue Recognition

     Revenue includes fees for waste processing services and technology license
fees. Revenue from waste processing is recognized upon the completion of the
waste treatment process. Revenue from licensing or technology transfer
agreements is recognized when received unless there are future commitments, in
which case the revenue is recognized over the term of the agreement.

     Revenue under cost plus, fixed fee and fixed unit price contracts mainly
relating to site remediation is recorded as costs are incurred or units are
completed and include estimated fees earned according to the terms of the
contracts.  Revenue from U.S. federal government contracts include estimates of
reimbursable overhead and general administrative expenses, which are subject to
final determination by the U.S. federal government upon project completion.
Change orders are modifications of an original contract that effectively change
the provisions of the contract.  They may be initiated by either the Company or
the customer. Change order work may be performed prior to approval of the change
order by the customer. Revisions in contract revenue and cost estimates are
reflected in the accounting period when known. Provision for the entire amount
of estimated losses on uncompleted contracts is made in the period such losses
are determined. Claims for additional contract revenue are recognized if it is
probable that the claim will result in additional revenue and the amount can be
reliably estimated.

     The Company's site remediation revenue for fixed price and cost plus
contracts is recognized on the percentage of completion basis. Consequently,
construction revenue and gross margin for each reporting period is determined on
a contract-by-contract basis by reference to estimates by the Company's
engineers of expected costs to be incurred to complete each project. These
estimates include provisions for known and anticipated cost overruns, if any
exist or are expected to occur. These estimates may be subject to revision in
the normal course of business.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments with original
maturities of three months or less to be cash equivalents.

  Balance Sheet Classifications

     The Company includes in current assets and liabilities amounts receivable
and payable under construction contracts, which may extend beyond one year. A
one-year time period is used as the basis for classifying all other current
assets and liabilities.

  Property and Equipment

     Property and equipment are stated at cost and are depreciated on the
straight-line basis over the estimated useful lives of the assets, which range
from three to forty years. The Company self constructs substantially all of its
waste processing facilities, and includes as captialized costs, direct materials
and labor and related overhead and cost of construction included certain
employee costs related to procurement, engineering and design, supervision,
subcontractor administration and permitting and testing. Cost includes
expenditures for major improvements and replacements and the net amount of
interest costs related to qualifying construction projects. Expenditures for
major renewals and betterments are capitalized. Expenditures for maintenance and
repair expenses are charged to expense as incurred. The Company's policy is to
regularly review the carrying amount of specialized assets and to evaluate the
remaining life and recoverability of such equipment in light of current market
conditions.

  Accounting for the Impairment of Long-lived assets

     The Company accounts for impairment of long-lived assets in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for
the Impairment of Long-Lived Assets to be Disposed of." SFAS No. 121 requires
that long-lived assets be reviewed for impairment whenever events or changes in
circumstances indicate the book value of the asset may not be recoverable. The
Company evaluates at each balance sheet date whether events and circumstances
have occurred that indicate possible impairment. In accordance with SFAS No.
121, the Company uses an estimate of the future undiscounted net cash flows of
the related asset or asset grouping over the remaining life in measuring whether
the assets are recoverable. Please see Note 3 for impairment charge discussion.

  Intangible Assets

     Intangible assets are stated at acquisition cost and are amortized on the
straight-line basis over the estimated useful lives of the assets, which range
from three to twenty-five years. Acquisition cost includes the value of patents,
licenses, non-compete covenants and goodwill.  The Company's policy is to
capitalize only such costs which are purchased.  The Company's policy is to
regularly review the carrying amount of intangible assets and to evaluate the
remaining life and recoverability of such assets in light of current market
conditions.

  Contingencies, Risks, and Uncertainties

  Environmental Permits

     The Company operates its fixed facilities under regulations of, and permits
issued by, various state and federal agencies.  The Company, typically, is in
the process of seeking new permits, renewals and/or expansion permits.  There
can be no assurance of the successful outcome of any permitting efforts.  The
permitting process is subject to regulatory approval, time delays, local
opposition and potentially stricter governmental regulation. In the event a
permit is not granted, facility construction programs could be delayed, changed,
or abandoned and could result in substantial losses which would have a material
adverse effect on the Company's consolidated financial position. The Company
reviews the status of permitting projects on a periodic basis to assess
realizability of related asset values.  As of December 31, 2000, management
believes that assets which could currently be affected by permitting efforts are
recoverable at their recorded values.

  Department of Energy -- Hanford

     In connection with the Company's contract with the Department of Energy's
Hanford Reservation (DOE Hanford), DOE Hanford by US federal law, was required
to commence non-thermal treatment of the DOE Hanford low-level mixed waste
stored in Richland, Washington by September 30, 1999, and thermal treatment of
this waste by December 31, 2000. ATG, which the Department of Energy contracted
with to process this waste, commenced non-thermal treatment of the waste by
December 1999 and thermal treatment by December 2000. Although ATG's contract
also required that ATG obtain all licenses, permits and approvals for, and place
our treatment facility for low-level mixed waste in operation by November 10,
2000, ATG did not meet this deadline due to the lack of completion of the
demonstration testing of our Richland facility. The Department of Energy has
been notified of the 2001 schedule for completion of demonstration testing and
ATG's violation of the November 10, 2000 deadline. To date, the Department of
Energy has not notified ATG of any corrective actions nor has ATG obtained a
waiver of this violation.

  Governmental Regulation

     ATG may not be able to comply with all of the environmental and other
regulatory requirements applicable to ATG's business, which could prevent ATG
from operating the business according to the business plan. If ATG fails to
timely obtain, or to comply with the conditions of applicable federal, state and
local governmental licenses, permits or approvals for the Company's waste
treatment facilities and services, ATG could be prevented from operating the
facilities and providing services, resulting in a significant loss of revenue.
ATG is required to complete thermal demonstration testing to receive approval to
become fully operational at the ATG processing facility for low-level mixed
waste in Richland, Washington. ATG is scheduled to conduct demonstration testing
in 2001. The cost to complete this testing is approximately $2 million. ATG
currently does not have the funds to complete demonstration testing. ATG must
acquire the $2 million from additional equity or debt financing or from a
government funded research and development program at the Department of Energy.
Currently, the regulatory authorities are allowing ATG to process contracted
waste streams as ATG prepares for demonstration testing. The regulatory agencies
allow up to 720 hours, or with an extension, up to 1440 hours, of waste stream
processing prior to demonstration testing. After completion of these 720 hours,
or 1440 hours if an extension has been granted, ATG will no longer be able to
process contracted waste streams at our Richland facility without successful
completion of demonstration testing. ATG is targeting three months or
approximately until June 2001, to complete the initial 720 hours, and may
request an extension for an additional 720 hours from the regulatory agencies.
To date, ATG has processed approximately 310 hours of contracted waste streams.
Once thermal demonstration testing of the Richland facility has commenced, if
the thermal processing systems do not meet governmental standards, this would
delay or prevent this facility from becoming operational for thermal
decontamination of mixed waste, resulting in a loss of significant revenue
potential at this facility.

     In addition, licenses, permits and approvals for ATG's existing operational
facilities and services are subject to revocation or modification under a
variety of circumstances. As our business expands and as ATG introduces new
technologies, ATG will be required to obtain additional operating licenses,
permits or approvals. ATG may also be required to obtain additional operating
licenses, permits or approvals if new environmental legislation or regulations
are enacted or existing legislation or regulations are amended, reinterpreted or
enforced differently than in the past. Any new governmental requirements that
raise compliance standards may require us to modify our waste treatment
technologies to conform to more stringent regulatory requirements. ATG may not
be able to continue to comply with all of the environmental and other regulatory
requirements applicable to ATG's business.

     Company facilities may be shut down due to equipment failure or failure to
comply with government regulations, which could significantly reduce our
revenues. If any of the Company's principal waste treatment systems were to be
shut down for any appreciable period of time, because of either equipment
breakdown or regulatory action in response to an alleged safety or other
violation of the terms of the licenses under which we operate, our revenues
could be significantly reduced. A shutdown of operating facilities will result
in the loss of revenues and possibly other future potential revenues from future
contracts if the Company was not able to bid for contracts successfully because
the waste treatment systems at the Company's fixed facilities did not perform
consistently in conformance with safety and other requirements. ATG's fixed
facilities are subject to frequent routine inspections by the regulatory
authorities issuing the licenses. The SAFGLAS system was shut down from
September 5 to September 28, 1999 due to an equipment failure, resulting in
business interruption losses and property damage of $2.7 million, of which to
date only $829,000 has been reimbursed by insurance. ATG has experienced other
shutdowns of our facilities for short periods of time in the past.

  Dependence on Large Customers

     A loss on one or more of the Company's larger contracts could significantly
reduce the Company's revenues. If ATG is unable to accurately calculate or
integrate the cost of performing a large, multi-year contract in its contract
bid and the costs are understated significantly, ATG would likely incur a loss
which would significantly reduce the Company's revenues. ATG increasingly
pursues large, governmental and private sector, multi-year contracts as a method
of achieving more predictable revenue, more consistent utilization of equipment
and personnel, and greater leverage of sales and marketing costs. The government
contracts in particular are usually awarded as a result of a competitive bidding
process requiring ATG to estimate and accurately predict its cost of
performance. These large contracts impose significant risks if actual costs are
higher than those estimated by ATG at the time of bid.

  Litigation

     The Company in the normal course of business has pending litigation. If the
Company were to lose any of three pending civil actions, including a wrongful
death action, the Company may be subject to a potentially large damage award.
ATG is a defendant in a pending wrongful death civil action seeking damages in
excess of $8 million, including exemplary damages of $5 million, for the death
of an employee of a scrap metal dealer who died as a result of an exploding
piece of ordnance. The action alleges that ATG's sub-contractor supplied the
ordnance to the scrap dealer. A second lawsuit seeking damages of $200 was filed
by three other persons alleging physical injuries and emotional distress caused
by the accident. A third lawsuit seeking damages of $1.2 million was filed by
the property owner where the explosion occurred alleging business interruption
and property damage. ATG is a named defendant in the second and third actions as
well.

  Income Taxes

     Deferred taxes are provided on a liability method whereby deferred tax
assets are recognized for deductible temporary differences and operating loss
carryforwards and deferred tax liabilities are recognized for taxable temporary
differences. Temporary differences are the differences between the reported
amounts of assets and liabilities and their tax bases. Deferred tax assets are
reduced by a valuation allowance when, in the opinion of management, it is more
likely than not that some portion or all of the deferred tax assets will not be
realized. Deferred tax assets and liabilities are adjusted for the effects of
changes in tax laws and rates on the date of enactment.

  Concentration of Credit Risk

     The majority of the Company's cash and cash equivalents are held with major
banks in the United States.  The Company's customers consist mainly of agencies
of the U.S. government and large U.S. companies.  The Company performs ongoing
credit evaluation of its customers' financial condition. As of December 31,
2000, agencies of the U.S.government represented 55% of accounts receivable and
30% of total revenue for the year then ended. As of December 31,1999, agencies
of the U.S. government represented 39% of accounts receivable and 27% of total
revenue for the year then ended. As of December 31, 1998, agencies of the U.S.
government represented 51% of accounts receivable and 55% of total revenue for
the year then ended. The Company generally does not require collateral.

  Computation of Net Income/(Loss) Per Share

     Basic income per share is computed by dividing net income/(loss) available
to common shareholders by the weighted average number of common shares
outstanding for the period. Diluted income per share is computed giving effect
to all dilutive potential common shares that were outstanding during the period.

  Stock Options

     The Company accounts for stock-based awards to employees in accordance with
APB No. 25 ("APB 25"), Accounting for Stock Issued to Employees, and has adopted
the disclosure-only alternative of Statement of Financial Accounting Standards
No. 123 ("SFAS 123"), Accounting for Stock Based Compensation. See Note 11,
Stock Based Compensation Plans for further details.

  Reclassifications

     Certain prior year amounts in the consolidated financial statements have
been reclassified to conform with the current year's presentation.

3. Acquisition of Business and Subsequent Abandonment of Assets

Acquisition

     Effective December 1, 1998, the Company, through its wholly-owned
subsidiary, ATG Nuclear, and through its subsidiary, ATG Catalytics, acquired
certain assets and business lines from the trustee ("Seller") for debtors of
Molten Metal Technologies, Inc. or its affiliates, under Chapter 11 of the
United States Bankruptcy Code (the "MMT Assets").

     The assets acquired by ATG Nuclear include substantially all of the assets,
contracts, licenses and permits associated with the Seller's wet waste business
based in Oak Ridge, Tennessee, and a facility in Columbia, South Carolina.  The
assets acquired by ATG Catalytics include substantially all of the assets,
contracts, licenses and permits associated with the Seller's catalytic
extraction processing business conducted substantially in Oak Ridge, Tennessee.

     These assets were acquired through a combination of cash, notes payable,
and the assumption of certain debts, including the obligation to provide for
disposal of certain legacy wastes which were in process at the date of
acquisition. The Company paid $10.5 million in cash at closing, agreed to pay
$1.0 million in cash one year from closing and agreed to make future payments of
5% of the earnings before interest, taxes, depreciation and amortization of ATG
Catalytics, but not less than $800 annually for five years (minimum of $4.0
million).

     The transaction has been accounted for as a purchase and, accordingly,
results of operations include the operations of the new businesses since the
date of acquisition. The purchase price has been allocated to the net assets
acquired and will be amortized over the lives of those assets.

Restructuring

     During the quarter ended June 30, 2000, the Company announced and completed
a restructuring plan, which included a workforce reduction of approximately 110
employees at its Tennessee facilities. The plan was primarily aimed at improving
cost efficiencies and waste treatment processes. The Company recorded a $500
maintenance supply inventory write-down and a restructuring charge of $1.9
million which included non cash charges of $800 for equipment taken out of
service and abandoned.
Asset Abandonment

     During the fourth quarter of 2000, the Company completed a review of the
Tennessee fixed facilities concerning the utilization of a modified Q-CEP
thermal treatment system for the processing of specialty niche waste streams.
Due to the prohibitive cost and the unknown prospect of success related to the
proposed system modification, the Company formally abandoned the Q-CEP thermal
treatment system during the fourth quarter of 2000 and recorded a non cash asset
impairment charge of $14.1 million. In addition, the Company recorded non cash
charges regarding the $1.4 million write-down of goodwill from its acquisition
of the Q-CEP assets, a $307 maintenance supply inventory write-down that was
charged to cost of revenue, and an $828 write-down of other assets. Furthermore,
a charge of $1.2 million was recorded for processing and disposal of secondary
waste associated with the shutdown of the Q-CEP facility, of which $1.0 million
remains accrued at December 31, 2000.

The number of claims is two as of December 31, 2000 and 1999.
These amounts have been recognized as revenue and include only direct costs
associated with the claim and do not include profit margin. The Company is in
the process of submitting contract documents related to these claims. The
customer may accept or reject the Company's claim. Should the customer reject
the claim, the Company may be required to seek alternative remedies, including
litigation.

5. Restricted Investments

     The Company has restricted cash of $149 and $16,014 as of December 31, 2000

     Property and equipment costs include capitalized labor and overhead,
including interest costs related to the construction of buildings, building
improvements and equipment. Capitalized interest costs totaled $3,406, $1,410,
and $1,027, in 2000, 1999, and 1998 respectively. Depreciation and amortization
expense on property and equipment was $2,918, $1,809, and $765 in 2000, 1999,
and 1998, respectively, and a portion is included in cost of revenue in the
amount of $385, $675, and zero, in 2000, 1999, and 1998 respectively. All
property and equipment serve as collateral to notes payable agreements to banks
and other creditors.

     Mixed Waste Facility

     During 1999, construction of the Company's new mixed waste treatment
facility in Richland, Washington began and was substantially completed during
2000 resulting in a substantial increase in property and equipment over the
prior year and a decrease in construction in progress over the prior year. The
facility began operations in nonthermal treatment lines in late 1999 and thermal
treatment lines in late 2000. The facility is financed by the issuance of $26.5
million of tax-exempt Solid Waste Revenue Bonds. See Note 9 - Borrowing
Arrangements for further details.

8. Transactions with Related Parties

     On June 30, 2000, ATG sold a total of 2,000,000 shares of common stock for
$2.00 per share in a private placement to Special Situations Fund III, L.P.,
Special Situations Cayman Fund, L.P. and Special Situations Private Equity Fund,
L.P. The stock purchase agreements require ATG to file a registration statement
with the SEC to register the resale of the private placement shares. If the
registration statement is not filed within 45 days and effective within 120
days, then the stock purchase agreements require ATG to issue additional shares
of common stock to the funds in amounts calculated based on the length of the
delays, but not to exceed 36% of the number of private placement shares. Because
the registration statement was filed after more than 45 days and was not
effective within 120 days, the funds became entitled to receive 240,000
additional shares up to a maximum of 720,000 shares of common stock as provided
in the stock purchase agreements.

     However, on December 29, 2000, ATG entered into a settlement agreement with
the funds whereby ATG and the funds settled disputes about their respective
rights and obligations under the stock purchase agreements. The funds agreed to
waive their rights under the stock purchase agreements to receive additional
shares of common stock and other alleged rights in exchange for a one-time
right, exercisable by written notice to ATG on or before November 15, 2001, to
have the price of their private placement shares reset. The reset right will be
based on the average closing price of ATG common stock for the 30 trading days
prior to November 1, 2001 if less than $2.00 per share, except that the price
may not be reset to a price that is lower than the average closing price of ATG
common stock for the 15 trading days prior to December 27, 2000. ATG may be
required to issue up to a maximum of 2,050,632 shares of common stock pursuant
to the terms of the reset right. Under the settlement agreement, ATG is not
required to honor any reset notice from the funds if, within ten business days
after receiving the notice, ATG repurchases all of the funds' private placement
shares for $2.00 per share. The settlement agreement further provides that if
ATG's registration statement is not effective by March 31, 2001, then the funds'
rights to receive additional shares under the stock purchase agreements will
automatically be reinstated.

                                       54

     The Company has a note payable to a former Director of $225 at December 31,
2000 and 1999.  The amount is due December 31, 2001. The amount is included in
short term debt at December 31, 2000.

     The President and Executive Vice-President and directors of ATG, have each
guaranteed the obligations of ATG under (i) two promissory notes in the
principal amounts of $2,069 and $1,996 held by a financial institution; (ii) a
commercial lease agreement between ATG and another financial institution with an
aggregate rental amount of $103; and a promissory note in the principal amount
of $1,500 held by an individual.

     In connection with the issuance of certain bonds, undertakings and other
instruments of guarantee in favor of ATG, the President and Executive Vice-
President have each executed (i) a blanket indemnity agreement in favor of an
insurance company, indemnifying the insurance company against any losses that
the insurance company may incur in connection with the issuance of any such
bonds, undertakings or other instruments of guarantee, and (ii) a blanket
Continuing Agreement of Indemnity - Contractor's Form for the benefit of
three other insurance companies, indemnifying such entities against any losses
that such entities may incur in connection with the issuance of any such bonds,
undertakings or other instruments of guarantee. As of December 31, 2000, the
potential aggregate liability of the President and Executive Vice-President
under the blanket indemnities was approximately $36.

     During 2000, the President and Executive Vice President advanced $1,005 to
ATG. This amount is included in the balance sheet caption "accounts payable" and
bears interest at the rate of 12%.

     In 1998, the Company entered into a demolition and construction management
project with a partnership in which the President and Executive Vice President
of the Company have a combined 50% ownership interest.  The total contract value
is approximately $4,967 of which revenues of $2,779 and $1,403 were recognized
in 2000 and 1999 respectively.  Costs of $2,423 and $1,354 in 2000 and 1999,
respectively, are associated with this project. The related accounts receivable
include $848 and $857 at December 31, 2000 and 1999, respectively.

9. Borrowing Arrangements

     In November 1999, the Company completed an agreement with a consortium of
banks (the Banks) for a credit facility in the amount of $45 million. The credit
facility includes a letter of credit in support of tax-exempt Solid Waste
Revenue Bonds (the Bonds) in the aggregate face amount of $26.5 million (the
"letter of credit"). The Bonds were issued during November 1999, and bear
interest at a floating rate (5.10% at December 31, 2000), based upon prevailing
market conditions, which is redetermined every seven days. The Bonds are due
October 31, 2014 and may be prepaid at any time without penalty. The proceeds,
including the remaining restricted cash balance of $149 and $16.0 million as of
December 31, 2000 and 1999 respectively, are to be applied exclusively for the
construction of the Company's Low Level Mixed Waste facility in Richland,
Washington. The credit facility also includes a five year revolving working
capital line of credit, due October 2004,in the amount of $18 million, including
a letter of credit facility of $5 million. Borrowings, when made, bear a
variable interest rate based on certain financial ratio criteria. The Banks
provided additional borrowings of $5.75 million in April, 2000; the additional
borrowings were due June 30, 2000. The Company currently has borrowings of
$23.75 million at the Banks' default rate of 12.75%. The credit facility is
collateralized by accounts receivable, inventory and equipment.

     The credit facility agreement requires the Company to comply with certain
covenants, including capital asset acquisition limits, limits on additional
debt, minimum levels of tangible

                                       55
<PAGE>

net worth, dividend payment restrictions and maintenance of certain financial
ratios. The Company failed to meet as of December 31, 2000, and for each of the
quarterly periods in the year ended December 31, 2000 certain financial covenant
ratios.

     As discussed in Note 18, at March 31, 2000 ATG was in violation of the
revised financial ratios under the credit facility. Pursuant to a forbearance
and consent agreement dated as of June 1, 2000, the lenders agreed to forbear in
the exercise of any of their rights or remedies with respect to March 31, 2000
covenant defaults until no later than June 30, 2000. At June 30, 2000, ATG
failed to make a required payment of principal in the approximate amount of
$5,750 as a mandatory pay-down under the revolving credit facility, so as to
bring total borrowings under that facility to the $18 million limit. The
occurrence of an event of default would permit the lenders to accelerate the
maturity of borrowings already made under the credit facility and to prohibit
ATG from making additional borrowings under the facility. To date the lenders
have allowed ATG to draw under the facility and have not notified ATG of their
intention to accelerate repayment. Management believes that ATG will not be
able, on a prospective basis, to comply with the financial covenants in the
agreements governing the credit facility without significant accommodations from
the lending syndicate.

     ATG on August 11, 2000, obtained a short-term loan in the amount of $1,500
bearing a maturity date of October 5, 2000 from an individual lender. The loan
bears interest at a rate of 12% per annum. ATG was unable to repay the loan on
its stated maturity date and subsequently obtained an extension until December
15, 2000. ATG is seeking to obtain an extension to the December 15, 2000 due
date, but to date has not obtained this extension. ATG anticipates that it will
need to obtain additional financing or obtain another extension on the due date
in order to repay the loan.

  Long Term Debt

     Long term debt consists of mortgage debt, notes payable, equipment notes
payable and obligation under the letter of credit. The mortgage debt bears
interest at the annual rate of 8.125%, matures in 2006, and is collateralized by
certain of the Company's buildings.  The notes payable bear interest at annual
rates between 8% and 10%, mature between 2001 and 2005, and are collateralized
by certain of the Company's equipment. In addition, notes payable includes the
Banks' five year long term revolving credit line that is discussed in the
previous section. Equipment notes bear interest at annual rates between 0.9% and
9.0%, mature between 2001 and 2002, and are collateralized by specific
equipment.

     Future minimum principal payments are as follows as of December 31, 2000:

10. Commitments and Contingencies

     In June 1992, ATG entered into a contract with the U.S. Army under which
ATG acted as the prime contractor to "surface clear" expended ordnance from a
firing range at Fort Irwin, California. In March 1997, a piece of ordnance
exploded on the premises of a scrap metal dealer in Fontana, California. An
employee of the scrap dealer died in the accident. Although the scrap dealer had
purchased expended ordnance and other military scrap metal from a number of
military facilities, including Fort Irwin, the scrap dealer indicated that the
ordnance which exploded was purchased from Fort Irwin. The U.S. Army contended
that a subcontractor to ATG on the Fort Irwin contract had improperly certified
ordnance cleared from the Fort Irwin firing range as free of hazardous and
explosive material prior to the sale of ordnance to the scrap dealer. As a
result, the U.S. Army terminated the Fort Irwin contract for default, and
demanded repayment from ATG of alleged reprocurement costs totaling $945,000.
ATG believes it fully complied with the terms of the Fort Irwin contract and
applicable laws and regulations and challenged the default termination in an
action against the U.S. Army filed in the Court of Federal Claims in July 1997.
In July 1998, the U.S. Army and ATG settled the matter. The termination for
default was rescinded and ATG agreed to no longer bid on surface-clearing work
at active U.S. Army firing ranges.

     In connection with the accident, in March 1998 a wrongful death civil
action was filed in San Bernardino County Superior Court against the
subcontractor, a supervisory employee of the subcontractor, the owners of the
premises occupied by the scrap dealer, and ATG, seeking damages in excess of $8
million, including exemplary damages of $5 million. A second action was filed at
the same time in San Bernardino County Superior Court against the same
defendants by three other persons alleging physical injuries and emotional
distress caused by the accident. The parties in the second action are seeking
general damages subject to proof estimated to be in the amount of $200. A third
action was also filed in San Bernardino County Superior Court against the same
defendants by the property owner where the accident occurred asserting business
interruption and property damage caused by the accident in the amount of $1,200.
ATG has tendered the defense of each of these actions to its insurance carrier,
which is presently handling the matters for ATG, and we intend to vigorously
contest all of the claims asserted in these actions. We believe that we acted
properly with respect to the Fort Irwin contract, and that we should not be
liable for the injuries caused by the accident. We also intend to seek
indemnification from the subcontractor for the full amount of any costs, damages
and liabilities which we may incur in connection with or as a result of these
lawsuits. The subcontractor has advised ATG that the subcontractor's
comprehensive general liability insurance policy covers the claims asserted
against the subcontractor, and that the policy coverage limit is $7 million per
occurrence. Although we believe that all of the claims asserted against ATG are
without legal merit, the
                                       57
<PAGE>

outcome of these lawsuits is uncertain. Any judgment of liability against ATG,
especially to the extent damages exceed or are not covered by insurance or are
not recoverable by ATG from the subcontractor, could have a material adverse
effect on our business, financial condition and results of operations.

     In addition to the contingency disclosed above, from time to time we are a
party to litigation or administrative proceedings relating to claims arising
from our operations in the normal course of business. Management, on the advice
of counsel, believes that the ultimate resolution of litigation currently
pending against ATG is remote, either individually or in the aggregate, to have
a material adverse effect on our business, financial condition or results of
operations.

11. Stock Based Compensation Plans

  1994 Stock Option Plan ("1994 Plan")

     A total of 909,878 shares of common stock have been reserved for issuance
under the 1994 Plan.  Options granted under the 1994 Plan generally expire ten
years from the date of grant. The Company does not plan to issue further options
to purchase common stock under the 1994 Plan.

  1998 Stock Ownership Incentive Plan ("Incentive Plan")

     A total of 1,000,000 shares of common stock have been reserved for issuance
under the Incentive Plan.  The Board of Directors may grant incentive stock
options or non-statutory stock options to employees at 100% of the fair market
value of the stock on the date of grant.  Vesting terms are to be determined by
the Board of Directors (typically three years) and options generally expire ten
years from the date of grant.

  1998 Non-Employee Directors' Stock Option Plan ("Directors' Plan")

     A total of 200,000 shares of common stock has been reserved for issuance
under the Directors' Plan. The Directors' Plan provides for an automatic grant
of options to purchase 20,000 shares of common stock upon the date a person
becomes a non-employee director. Twenty-five percent of the shares subject to
the option are immediately vested and twenty-five percent vest each year
thereafter. The exercise price of the options granted under the Directors' Plan
must equal or exceed the fair market value of the Common Stock on the date of
grant. All options expire ten years from the date of grant.

  1998 Consultants and Advisors Stock Option Plan ("Consultants Plan")

     A total of 200,000 shares of common stock has been reserved for issuance
under the Consultants Plan. The Consultants Plan is administered by the Board of
Directors who may grant options to purchase common stock to consultants and
advisors to the Company at prices and upon terms as determined by the Board.

     As of December 31, 2000, options to purchase 793,338 shares of Common Stock
at $0.10 to $8.62 per share were fully vested and exercisable under the Plans.

     During August 1998, the Company cancelled options granted to employees to
acquire 125,500 shares of Common Stock with prices ranging from $8.50 to $8.56
and issued new options to acquire the same number of shares at a price of $6.375
per share.

     In connection with the grant of options for the purchase of 554,000 shares
of Common Stock to employees during the period from January 1, 1997 through
December 31, 1997, the Company recorded aggregate deferred compensation expense
of approximately $389 representing the difference between the deemed fair value
of the Common Stock and the option exercise price at date of grant. Such
deferred compensation is being amortized over the vesting period relating to
these options, of which $32 and $120 have been amortized during the years ended
December 31, 2000 and 1999, respectively, and is included in the statement of
operations within the caption "Stock-based compensation expense".

  Stock Compensation

     The Company applies APB Opinion No. 25, "Accounting for Stock Issued to
Employees", and related interpretations in accounting for its stock-based
compensation.  Determination of compensation cost for stock-based compensation
based on the fair value at the grant date for awards consistent with provisions

     As of December 31, 2000, the Company had net operating loss carryforwards
available to reduce its future taxable income of approximately $12,745 and
$11,773 respectively, for federal and state income tax purposes. The federal and
state net operating losses will expire between 2005 and 2020.

                                       61
<PAGE>

     For federal and state tax purposes, the Company's net operating loss
carryforwards may be subject to certain limitations on annual utilization in the
event of changes in ownership, as defined by federal and state law.

     During 2000, the Company determined that its cumulative net operating
losses incurred exceeded the amount of tax carry back available. Additionally,
due to the uncertainty of future recoverability, the Company recorded a full
valuation allowance against its deferred tax assets. The Company will provide a
full valuation against its deferred tax assets until such time as evidence shows
it is more likely than not that the deferred tax assets are recoverable.

     Options and warrants to purchase 1,530,000 and 888,000 and 352,000 shares
of Common Stock at exercise prices in excess of the average market price of the
Company's common stock were excluded from the computation of diluted earnings
per share as their effect would be anti-dilutive for 2000, 1999, and 1998,
respectively.

     Under agreements with the selling shareholders of the Company's private
placement common stock issuance of June 2000, ATG is currently required to issue
a total of 578,875 shares at December 31, 2000, that were excluded from the
computation of diluted earnings per share as their effect would be anti-
dilutive, and may be required to issue up to a maximum of 1,059,300 shares of
common stock to the selling shareholders without payment of additional
consideration. ATG may also be required to issue up to a maximum of 2,050,632
additional shares of common stock to three of the selling shareholders pursuant
to the terms of an agreement with these three selling shareholders should the
average closing price of ATG's stock for the 30 trading days prior to November
1, 2001 be less than $2.00 per share. The issuance of these additional shares
including the shares that may be issued should ATG's stock fall below $2.00 for
the 30 trading days prior to November 1, 2001 will have a dilutive effect.

15. Employee Retirement Plan

     The Company maintains a Qualified Retirement Plan (401(k) Plan) which
covers substantially all employees. Eligible employees may contribute up to 15%
of their annual compensation, as defined, to this plan. The Company may also
make a discretionary contribution. During 2000 and 1999, the Company contributed
$53 and $61 in matching funds through the issuance of shares of its common stock
to the 401(k) Plan. The Company did not contribute to the 401(k) Plan during
1998.

16. Sale of Corporate Facilities

     The Company sold to a less than 1% shareholder of the Company, the
Company's facility, building and land, located in Fremont California. The
Company transferred title to the building to the new owner on December 10, 1999.
The terms of the sale agreement includes a
                                       62
<PAGE>

sale price of $4.5 million, a deposit payment of $810 at the time of the
agreement, assumption of the mortgage debt collateralizing the building, and
obtaining additional funding to purchase the building. The sale agreement
includes a leaseback provision for a month to month lease provision for the
Company at existing market rates and conditions, allows the Company to vacate
the building with 60 day notice subject to other provisions, and allows the
Company the first right of refusal on a third party sale by the new owner. The
sale agreement requires the Company to obtain a certificate of compliance with
respect to certain environmental issues with regards to the building prior to
vacating the premises. The Company estimates that the certificate of compliance
will require, at a cost to the Company, the incurrence of $100 to clean up the
building and the duration of the clean up of at least 6 months.

     The Company had "continuing involvement" with the building subsequent to
the sale and was the primary debtor of the debt obligation on the building as of
December 31, 1999, and in accordance with generally accepted accounting
principles, the gain on the sale of the building was deferred pending
termination of its continued involvement. The deposit payment of $810 was
included within the balance sheet caption, "accrued liabilities" as of December
31, 1999. The Company continued to depreciate the building and account for the
building asset and debt as if owned by the Company. The Company has applied the
provisions of sale and leaseback accounting to the transaction in 2000 after the
Company no longer had any "continuing involvement" with the building.

17. Business Segments

     The Company manages its operations within two business segments: waste
processing, conducted by its Fixed Facilities Group (FFG); and field services,
conducted by its Field Engineering Group (FEG).  FFG processes customer waste
utilizing the Company's thermal and non-thermal technologies.  FEG performs
remediation, construction and various engineering services for customers under
long-term contracts.

     Prior to 1998, the Company evaluated its operations as one business unit.
Thermal processing of large volumes of waste began in 1998 and the Company
commenced evaluating its business as two business segments in the fourth quarter
of the year.  The Company segregates revenue and gross profit by business
segment.  Selling, general and administrative expenses are not allocated to the
business segments.  The accounting policies of the business segments are the
same as those described in the summary of significant accounting policies.

  The Company earned $673 and $3,300 in international revenue from customers in
Asia during 2000 and 1999, respectively, all of which was performed by FFG.
Substantially all of the segment revenues in 1998 were from customers in North
America. All revenues are denominated in U.S. dollars.

18.  Liquidity and Going Concern Considerations

The Company's operating results were adversely affected in 2000 as a result of a
major shortfall in spent ion exchange processing revenue at the Company's
facility in Tennessee. In the three month period ended December 31, 2000, (Note
3) the Company abandoned and shutdown a substantial portion of the operations of
the Tennessee facility.

In addition, operating results were adversely affected by the delay in capacity
expansion at its low-level radioactive waste thermal processing facility
originally planned to be completed in the quarter ended March 31, 2000 and
rescheduled for completion in 2001 due to restrictions imposed by lenders and
operational issues, resulting in lower than projected revenue and gross margin
amounts, and the elimination of a waste processing line at its Tennessee
facility, in June 2000 resulting in a $500 inventory writedown charge and a $1.9
million restructuring charge for the three months ended June 30, 2000.

Cash flow in 2000 was negatively affected by the Company's inability to collect
field services trade accounts as projected. As a result of the aforementioned
factors, the Company is in default of certain financial ratio covenant
provisions (debt service to tangible net worth, debt service coverage ratio, and
quick ratio) and the mandatory repayment of $5.7 million at June 30, 2000
related to the Company's credit facility at December 31, 2000 and each
measurement period within the year 2000.

ATG failed to make interest payments in the last quarter of 2000 of amounts
totaling $765 and failed to make interest payments in the first quarter of 2001
of amounts totaling $716. In addition, ATG failed to make fee payments of $60 in
the last quarter of 2000 and failed to make a letter of credit fee payment in
the first quarter of 2001 in the amount of $219. ATG also was unable to pay a
$1,500 short-term loan from an individual lender dated August 11, 2000 which was
originally due on October 5, 2000 and was subsequently extended to December 15,
2000. ATG is seeking to obtain an extension of the December 15, 2000 due date,
but to date has not obtained this extension.

The occurrence of an event of default permits the lenders to accelerate the
maturity of borrowings already made under the credit facility and may prohibit
ATG from making additional borrowings under the facility. While the lenders have
allowed ATG to draw under the facility and have not notified ATG of their
intention to accelerate repayment, management believes that ATG will not be
able, on a prospective basis, to comply with the financial covenants in the
agreements governing the credit facility without significant accommodations from
the lending syndicate. The aforementioned raises substantial doubt regarding
ATG's ability to continue as a going concern. The accompanying financial
statements have been prepared assuming that the company will continue as a going
concern. The financial statements do not include any adjustments that might
result from the outcome of this uncertainty.

ATG is reviewing alternative forms of financing in order to comply with the
credit facility agreement. Management is reviewing the company's business plan
with financial advisors and lenders with the objective of seeking appropriate
accommodations and to ascertain what actions can be taken to enhance liquidity
and generate cash to assist in paying the company's debt service. The company is
also evaluating potential changes in its capital structure and additional
financial resources. In June 2000 the company raised approximately $5.1 million
in additional equity through the sale of common stock, and $1.5 million in
short-term debt during August 2000.

The company's ability to meet its obligations in the normal course of business
is dependent upon, among other items, its ability to collect trade accounts
receivable, primarily field services trade accounts receivable, competitively
price services with the market at a profit, successfully bring on line its mixed
waste processing facility, add capacity to its low-level radioactive waste
thermal processing facility, return to profitable operations, obtain additional
financing and/or restructure the current debt agreement, and obtain waivers of
debt covenant violations.
