RISK FACTORS

An investment in shares of ATG common stock involves a high degree of risk.
You should carefully consider the following factors and the other information
contained in this prospectus before deciding to invest.

WE ARE IN DEFAULT UNDER ONE OF OUR CREDIT FACILITIES; AS A RESULT, OUR
LENDERS COULD ELECT TO ACCELERATE REPAYMENT OF ALL OUTSTANDING LOANS. As
discussed in more detail under the heading "Management's Discussion and Analysis
of Financial Condition and Results of Operations - Liquidity and Capital
Resources," in November 1999, we 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 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. The
credit facility was temporarily increased to $24 million from March 27, 2000
through June 30, 2000, and reverts back to $18 million subsequent to June 30,
2000. Borrowings, when made, bear a variable interest rate based on certain
financial ratio criteria. ATG currently has borrowings of $23.75 million and
currently is paying a default rate of 12.75%. The credit facility is
collateralized by accounts receivable, inventory and equipment.

The credit facility agreement requires ATG to comply with certain covenants,
including capital asset acquisition limits, limits on additional debt, minimum
levels of tangible net worth, dividend payment restrictions and maintenance of
certain financial ratios. At December 31, 1999, ATG was in violation of certain
financial ratio covenants. ATG has obtained a 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 certain financial ratio covenants
that ATG failed to meet as of December 31, 1999, 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 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.

The company 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 the company 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, the company obtained a short-term loan in the amount of
$1,500,000 from an individual lender. The loan bears interest at a rate of 12%
per annum and is due on October 5, 2000. The company anticipates that it will
need to obtain additional financing or obtain an extension on the due date
in order to repay the loan.

3
<PAGE>

ATG will not be able, without obtaining concessions from the banks or new
financing, to make the mandatory paydown of approximately $5,750,000 required
under the credit facility, or to comply with the current financial covenants set
forth in the agreements governing the credit facility.

As of September 20, 2000, 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. The company is continuing to negotiate with the
lenders to modify the financial covenants and the time frame for the mandatory
paydown. We are seeking alternative forms of financing in order to make the
mandatory paydown. We are also reviewing the company's business plan with the
company's 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. The company is also evaluating potential changes in its capital
structure and additional financial resources. We cannot assure you that we will
be successful in any of the foregoing endeavors. If ATG is unable to service its
indebtedness, the company may be required to alter its business plans,
restructure or refinance its indebtedness or seek additional equity capital. We
cannot assure you that these objective could be accomplished on favorable terms,
if at all.

WE MAY NOT BE ABLE TO OPERATE OUR BUSINESS ACCORDING TO OUR BUSINESS PLAN IF
WE CANNOT COMPLY WITH ALL OF THE ENVIRONMENTAL AND OTHER REGULATORY REQUIREMENTS
APPLICABLE TO OUR BUSINESS. The radioactive and hazardous waste management
industry is highly regulated. We may not be able to operate our business
according to our business plan if we cannot comply with all of the environmental
and other regulatory requirements applicable to our business. We are required to
have federal, state and local governmental licenses, permits and approvals for
our waste treatment facilities and services. For example, we must 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
cannot assure you that we will be successful in obtaining this approval. In
addition, our existing licenses, permits and approvals 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
requirements which 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. Our failure to obtain
timely, or to comply with the conditions of, applicable licenses, permits or
approvals could prevent us from operating our business according to our business
plan.

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. We are in the process of developing, refining and
implementing our technologies for the treatment of low-level radioactive waste,
low-level mixed waste and other wastes. Our future growth will be dependent in
part upon the acceptance and implementation of these technologies, particularly
our recently developed vitrification technologies for the thermal treatment of
low-level radioactive waste and low-level mixed waste and our recently acquired
technologies for treatment of ion exchange resin waste streams. We cannot assure
you that we

4
<PAGE>

will be able to successfully develop these technologies in the near future. Even
if we can develop these technologies, we may not be able to develop them in a
manner which would make them commercially viable. Our technologies for treatment
of waste compete with other technologies, as well as with more traditional
treatment, storage and disposal alternatives. We cannot assure you that our
vitrification and related technologies will prove to be commercially viable or
cost-effective as compared to other waste treatment or waste disposal methods.
Even if our technologies prove to be commercially viable, we cannot assure you
that our clients will select our technologies for use in future waste treatment
projects. 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. We cannot assure you that we
will be able to comply with this deadline. 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.

CHANGES IN ENVIRONMENTAL LAWS OR ENFORCEMENT ACTIVITIES BY GOVERNMENTAL
AGENCIES MAY AFFECT THE DEMAND FOR OUR SERVICES. A substantial portion 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.
Environmental laws and regulations are, and will continue to be, a principal
factor affecting demand for our services. The level of enforcement activities by
federal, state and local environmental protection agencies and changes in
environmental laws and regulations also affect the demand for our services. If
the requirements of compliance with environmental laws and regulations were to
be modified in the future, 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, could be adversely
affected.

THE CANCELLATION OR MODIFICATION OF OUR GOVERNMENT CONTRACTS OR A REDUCTION
IN GOVERNMENT FUNDING COULD SIGNIFICANTLY REDUCE OUR REVENUES. We expect that
the percentage of ATG's revenue attributable to federal government contracts
will continue to be substantial for the foreseeable future. Our government
contracts generally are 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. We are dependent on government appropriations to fund many of our
contracts. Efforts to reduce the federal budget deficit 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. Our
revenues may be reduced significantly if the government elects to cancel or
modify our government contracts, or fails to fund future restoration of cleanup
sites.

WE ARE SUBJECT TO FINES AND PENALTIES FOR FAILURE TO COMPLY WITH THE
REQUIREMENTS OF GOVERNMENT CONTRACTS. As a provider of services to federal and
other government agencies, we face risks associated with government contracting,
which could include substantial 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. Government
contracting requirements are complex, highly technical and subject to varying
interpretations. As a result of our government contracting business, we have
been, and expect to

5
<PAGE>

be in the future, the subject of audits, and may in the future be subject to
investigations, by government agencies. If we fail to comply with governmental
contracting requirements, the government could impose on us fines and penalties,
including disqualifying us from future government contract projects for a
significant period of time. Failure to comply with the terms of one or more of
our government contracts could also result in damage to our business reputation.

IF WE CANNOT RAISE ADDITIONAL CAPITAL, WE WILL NEED TO CURTAIL OR SCALE BACK
OUR PLANNED EXPANSION. We believe that ATG will need additional financing for
working capital and capital expenditure requirements in order to implement its
long-term business plan. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations - Liquidity and Capital Resources." We
successfully obtained approximately $27 million to finance the construction of
our facility for processing of low-level mixed waste in Richland, Washington
through the issuance of tax-exempt solid waste revenue bonds. We cannot assure
you that we will successfully complete construction of the facility with the
capital financing that we have raised to date. If we need to raise additional
capital to complete the project, we cannot assure you that we will obtain
financing on terms that are advantageous to ATG. If we are not successful in
raising additional capital, we will need to curtail or scale back our planned
expansion.

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. Revenue in the first and second quarters has historically been lower
than in the third and fourth quarters, as our customers have tended to ship
waste during the months in which transportation is less likely to be adversely
affected by weather conditions. 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. Due to
this variation in demand, our quarterly results fluctuate. Therefore, it is
possible that in future quarters, our operating results will not meet the
expectations of securities analysts and investors. If our operating results do
not meet the expectations of securities analysts and investors, the price of our
common stock could decline.

IF WE FAIL TO MANAGE OUR GROWTH EFFECTIVELY, OUR OPERATIONAL, MANAGERIAL AND
FINANCIAL RESOURCES MAY BE INADEQUATE. Since 1994, we have experienced
significant growth, attributable in large part to an 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 facility for processing of low-level mixed waste that is anticipated to
contribute to increased growth in 2000 and beyond. We are currently pursuing a
business plan intended to further expand our business domestically and
internationally. Our historical growth has placed, and any future growth may
place, significant demands on our operational, managerial and financial
resources. We cannot assure you that our current management and systems will be
adequate to address any future expansion of our business.

OUR FACILITIES MAY BE SHUT DOWN DUE TO EQUIPMENT FAILURE OR FAILURE TO COMPLY
WITH GOVERNMENT REGULATIONS, WHICH COULD SIGNIFICANTLY REDUCE OUR REVENUES. Our
ability to perform

6
<PAGE>

under current waste treatment contracts and to successfully bid for future
contracts is dependent upon the consistent performance of our waste treatment
systems at our fixed facilities in conformity with safety and other requirements
of the licenses under which we operate. Our fixed facilities are subject to
frequent routine inspections by the regulatory authorities issuing such
licenses. Our SAFGLAS system was shut down from September 5 to September 28,
1999 due to an equipment failure, and we have experienced other shutdowns of our
facilities for short periods of time in the past. In the event that any of our
principal waste treatment systems were to be shut down for any appreciable
period of time, either due to equipment breakdown or as the result of 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.

WE FACE COMPETITION FROM COMPANIES WITH GREATER RESOURCES AND POTENTIALLY
MORE COST-EFFECTIVE WASTE TREATMENT SOLUTIONS. The market for radioactive and
hazardous waste management services is highly competitive. We face competition
in our principal current and planned business lines from both established
domestic companies and foreign companies attempting to introduce European waste
treatment technologies into the United States. Many of our competitors have
greater financial, managerial, technical and marketing resources. If our
competitors possess or develop superior or more cost-effective waste treatment
solutions or field service capabilities than ours, our ability to compete
effectively could be adversely affected. Any increase in the number of licensed
commercial treatment facilities or disposal sites for low-level radioactive
waste and/or low-level mixed waste in the United States, or any decrease in the
treatment or disposal fees charged by such facilities or sites, could reduce the
competitive advantage of our treatment technologies.

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. We cannot assure you that we or our
strategic alliance partners will be able to market our technologies or services
successfully in foreign markets. In addition, there are risks 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. These risks, in particular, recent economic
instability in certain Pacific Rim countries, could substantially impede our
planned expansion into that region.

IF WE LOSE THE SERVICES OF ANY OF OUR MANAGERIAL, TECHNICAL OR MARKETING
PERSONNEL, OUR ABILITY TO SERVICE THE NEEDS OF OUR CLIENTS COULD BE ADVERSELY
AFFECTED. Our future success depends on our continuing ability to attract,
retain and motivate highly qualified managerial, technical and marketing
personnel. ATG is highly dependent upon the continuing contributions of its key
managerial, technical and marketing personnel. Our employees may voluntarily
terminate their employment with ATG at any time, and competition for qualified
technical personnel, in particular, is intense. The loss of the services of any
of our managerial, technical or marketing personnel could adversely affect our
ability to service the needs of our clients.

7
<PAGE>

A LOSS ON ONE OR MORE OF OUR LARGER CONTRACTS COULD SIGNIFICANTLY REDUCE OUR
REVENUES. ATG increasingly pursues large, 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. These larger
projects impose significant risks if actual costs are higher than those
estimated at the time of bid. If we experienced a loss on one or more of our
larger contracts, or if we failed to obtain, or experience delays in obtaining,
large multi-year contracts, we could earn significantly less revenue than
anticipated.

A JUDGMENT OF LIABILITY RECOVERED AGAINST US IN A PENDING WRONGFUL DEATH
CIVIL ACTION COULD HAVE AN ADVERSE EFFECT ON OUR BUSINESS, FINANCIAL CONDITION
AND RESULTS OF OPERATIONS. 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 such 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. 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 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 an adverse effect on our business, financial condition and results of
operations.

<PAGE>

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. The bid and
offer quotations and compensation information must be provided prior to
effecting the transaction and must be contained on the customer's confirmation.
If brokers become subject to the "penny stock" rules when engaging in
transactions in our securities, they would become less willing to engage in such
transactions. This, in turn, would make it more difficult for owners of our
common stock to dispose of their shares.

CAUTION ABOUT FORWARD-LOOKING STATEMENTS

To the extent that the information presented in this prospectus, and in other
documents which are incorporated by reference in this prospectus under the
section of this prospectus entitled "Where You Can Find More Information,"
discusses financial projections, information or expectations about our business
plans, results of operations, products or markets, or otherwise makes statements
about future events, such statements are forward-looking. Such forward-looking
statements can be identified by the use of words such as "intends,"
"anticipates," "believes," "estimates," "projects," "forecasts," "expects,"
"plans," and "proposes." Although we believe that the expectations reflected in
these forward-looking statements are based on reasonable assumptions, there are
a number of risks and uncertainties that could cause actual results to differ
materially from such forward-looking statements. These include, among others,
the cautionary statements in the "Risk Factors" section of this prospectus
beginning on page 3. These cautionary statements identify important factors that
could cause actual results to differ materially from those described in the
forward-looking statements. When considering forward-looking statements in this
prospectus, you should keep in mind the cautionary statements in the "Risk

DIVIDEND POLICY

ATG currently intends to retain any future earnings for use in the operation
and growth of its business. We have never paid, and do not anticipate paying in
the foreseeable future, any cash dividends on our common stock. Any future
decision to declare or pay cash dividends on our common stock will depend upon
our results of operations, financial condition and our capital expenditure plans
at that time, as well as other factors that our board of directors, in its sole
discretion, may consider relevant. In addition, the terms of our bank borrowings
currently prohibit the payment by ATG of cash dividends on its common stock
without the lender's prior approval.

DETERMINATION OF OFFERING PRICE

The selling shareholders may, from time to time, offer their shares through
public or private transactions at prevailing market prices or privately
negotiated prices.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion contains forward-looking statements that involve
known and unknown risks and uncertainties which may cause our actual results in
future periods to differ materially from those indicated herein as a result of
certain factors, including those set forth under "Certain Business
Considerations." We undertake no obligation to publicly release updates or
revisions to these statements.

The following discussion should be read in conjunction with unaudited
condensed consolidated financial statements and the notes thereto for the six
months ended June 30, 2000 included elsewhere in this prospectus and the audited
consolidated financial statements and notes thereto for the fiscal year ended
December 31, 1999, also included elsewhere in this prospectus.

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 such as 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 newly acquired 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 of low-level mixed
waste at this facility in late December 1999.

The U.S. government represented approximately 27%, 55% and 71% of ATG's
total revenue for the years 1999, 1998 and 1997, 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 technology
transfer agreements involving up-front, non-refundable, licensing fees payable
to ATG, and due to the extensive expertise we have has developed in this area,
when we are processing radioactive waste, while margins on nonradioactive waste
projects generally are lower. In 1999, we focused a significant portion of

14
<PAGE>

our business on SAFGLAS(TM) vitrification of low-level radioactive waste, on our
newly acquired Tennessee business interests and processing of low-level mixed
waste, and we intend to continue this focus in 2000. During 1998 we focused a
significant portion of our business on SAFGLAS(TM) vitrification of low-level
radioactive waste. During 1997 we entered into two technology transfer
agreements with licensees in selected Asian territories and we intend to
continue to seek additional such licensing arrangements as appropriate
opportunities arise.

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.

ATG has historically relied upon the integration of proven technologies
with the company'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. Such 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 such 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.

During April 2000, ATG announced the consolidation of its 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, the company's Q-CEP thermal process is being replaced by
a more cost effective non-thermal resin decontamination process. See the section
entitled "Comparison of Six Months Ended June 30, 2000 and 1999 --Results of
Operations -- Revenue and Net Income" for further discussion.

COMPARISON OF SIX MONTHS ENDED JUNE 30, 2000 AND 1999

RESULTS OF OPERATIONS

Revenue and Net Income. For the six months ended June 30, 2000 revenue was $22.2
million, a decrease of 23% from the $29.0 million recorded for the same period
in 1999. The company recorded a net loss of $1.6 million, or $0.12 per share for
the six months ended June 30, 2000, compared to net income of $2.8 million, or
$0.19 per share fully diluted, for the same period in 1999. Excluding the pre-
tax $2.4 million restructuring charge related to the Tennessee plant
consolidation and workforce reduction and the $420,000 gain from the sale and
leaseback of the company's corporate offices, the company's net loss from
continuing operations would have been approximately $460,000 or $0.03 per share
for the six months ended June 30, 2000.

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. This is anticipated to be 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

16
<PAGE>

the second quarter of fiscal 2000. At the same time, our Q-CEP thermal process
is being replaced by a more cost effective non-thermal resin decontamination
process. As a result, the company has recorded a $2.4 million charge in the
second quarter of fiscal 2000 related to the plant consolidation and workforce
reduction.

Gross Profit. Gross profit for the six months ended June 30, 2000, was $8.4
million, or 38% of revenue, compared to $11.5 million, or 39% of revenue, for
the comparable period 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 approximately 42% in the six months ended June 30, 2000,
compared to 46% in the six months ended June 30, 1999. The decrease is
principally due to low-level radioactive waste thermal capacity constraints at
the Richland, Washington facilities which caused certain waste streams to be
processed non-thermally resulting in increased waste disposal charges that
unfavorably impacted gross profit. We are currently upgrading our Richland low-
level radioactive waste thermal facility and anticipate bringing increased
capacity online by the end of the third quarter of fiscal 2000. The decrease in
the six months ended June 30, 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, so
increases in utilization favorably impact gross profit while decreases in
utilization unfavorably impact gross profit.

Overall gross profit on field service projects was approximately 21% in the six
months ended June 30, 2000, compared to 15% in the six months ended June 30,
1999. The principal reason for the difference is the mix of projects and stage
of completion as many projects were utilizing less 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.

Sales, General and Administrative Expenses. Sales, general and administrative
expenses for the six months ended June 30, 2000 were $8.0 million or 36% of
revenue, compared to $6.2 million or 21% of revenue for the comparable period in
1999. The increase in spending from year to year is principally due to an
increase in infrastructure at our Richland facility. The increased
infrastructure is required for the company to meet its contractual obligations
regarding the start-up of its mixed waste processing operations. 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

17
<PAGE>

announced workforce reduction was completed by the end of the second quarter of
fiscal 2000 resulting in the company recording a $2.4 million charge in the
second quarter of fiscal 2000 related to the plant consolidation and workforce
reduction, of which an accrued liability of $698,000 remains unpaid at June 30,
2000. See the section entitled "Revenue and Net Income" for further discussion.

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.

Provision for Income Taxes. The company provides for income taxes during interim
periods at an estimated combined Federal and state annual rate to be expected
for the full year. The actual rate for 1999 was approximately 40% and the
company and is providing for income taxes at this same rate.

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 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.

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

18
<PAGE>

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.

COMPARISON OF YEARS ENDED DECEMBER 31, 1998 AND 1997

Revenue. Revenue for 1998 was $35.9 million, an increase of $16.8 million,
or 87.9%, compared to $19.1 million in 1997. The growth in revenue was
principally due to the increasing commercial utilization of our SAFGLAS(TM)
thermal treatment system. The SAFGLAS(TM) system began treating customer waste
streams in late 1997 and there was a steady increase in the volume being
processed during 1998. At the end of 1997, we had general service agreements in
place with only four nuclear power reactors, a key target customer for the
SAFGLAS(TM) technology. By the fourth quarter of 1998, customer service
agreements were in place with over 50 nuclear power reactors. With the
acquisition of new business lines in Oak Ridge, Tennessee, the number of such
reactors utilizing at least one of our technologies increased to over 90 at
December 31, 1998. In addition to the increase in waste for thermal treatment
utilizing SAFGLAS,(TM) these same customers were sending us increasing volumes
of waste to be treated through non-thermal means.

19
<PAGE>

In addition to SAFGLAS(TM) related revenue increases, ATG's revenues from
field service engineering grew by approximately 30% as a result of several large
awards from Department of Defense and Department of Energy customers. One
contract with the U.S. Air Force accounted for 14% of our total revenue in the
year ended December 31, 1998. Finally, approximately 7% of the revenue for 1998
resulted from the new business acquired for the processing of ion exchange resin
waste streams.

Gross Profit. Gross profit for 1998 was $16.1 million, an increase of $8.1
million, or 102.7%, compared to $7.9 million for 1997. Gross profit as a
percentage of revenue increased to 44.8% in 1998 compared to 41.5% in 1997.
Gross profit percentages reflect the various mixes of our business services from
time to time. Gross profit margins are generally higher, reflecting its
extensive expertise and operating efficiencies, when we are processing
radioactive waste, while margins on non-radioactive waste projects generally are
lower. The fixed facility operations, such as SAFGLAS(TM), have a larger
percentage of fixed costs versus variable costs, so increases in utilization,
such as occurred in 1998, favorably impact gross profit realized.

Sales, General and Administrative Expenses. Sales, general and
administrative expenses (including stock-based compensation expense) were $8.0
million for 1998, an increase of $0.9 million, or 13.3%, compared to $7.0
million in 1997. Sales, general and administrative expenses were 22.2% of
revenue in 1998, compared to 36.7% of revenue in 1997. The increase in spending
from year to year reflected the growth in ATG's operations, addition of sales
personnel and the increased costs of being a public company, offset by increased
absorption of indirect engineering and operating overhead. The overall decrease
as a percentage of revenue was attributable to our effort to maintain a level of
costs that does not increase at the same rate as revenue. Sales, general and
administrative expenses include indirect engineering and operating overhead,
depreciation and amortization, and expenses to support domestic sales and
marketing activities and financial and administrative functions.

Interest Income and Interest Expense. Interest income was $188,000 in 1998,
compared to $58,000 in 1997. The increase in interest income was directly
related to the investment of the proceeds from our initial public offering
completed in May 1998. Interest expense was nil in 1998 as the result of
capitalizing approximately $1.0 million of interest on construction in progress
in accordance with generally accepted accounting principles.

Provision for Income Taxes. In 1998, we provided for income taxes at a
combined federal and state effective tax rate of 38%. In prior years ATG
realized the benefit of net operating loss carry forwards. All net operating
loss carry forwards were fully recognized by the end of 1997.

LIQUIDITY AND CAPITAL RESOURCES

Total cash and cash equivalents were $4.5 million at June 30, 2000, an
increase of $1.7 million from December 31, 1999. The working capital deficit of
the company was approximately $16.2 million at June 30, 2000, a decrease of
$19.5 million from working capital of $3.3 million at December 31, 1999. The
working capital calculation excludes restricted cash of $3.6 million and
accounts payable of $1.7 million at June 30, 2000, and 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 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. See
discussion of the company's credit facility below.

20
<PAGE>

Total cash and cash equivalents were $2.8 million at December 31, 1999, a
decrease of $1.0 million from December 31, 1998. ATG's working capital was
approximately $3.3 million at December 31, 1999, an increase of $1.7 million
from December 31, 1998. The working capital calculation excludes restricted cash
of $16.0 million and accounts payable of $3.5 million that are exclusively for
the construction of our low-level mixed waste facility. The increase in working
capital is primarily due to ATG completing its new $45 million credit facility,
as described below, whereby its revolving line of credit is under a long term
agreement, net of cash used to acquire property and equipment.

During June and July 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,
the company completed the second tranche of the private placement, issuing
130,000 shares of common stock for an aggregate purchase price of $260,000. See
Part II, Item 15, entitled, "Recent Sales of Unregistered Securities." 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 $33.2 million, $5.0
million and $7.8 million for the years ended December 31, 1999, 1998 and 1997,
respectively, and totaled $14.3 million for the six months ended June 30, 2000.
In addition, we used approximately $3.0 million of cash during 1999 relating to
the purchase accounting for our acquisition of the assets of Molten Metal
Technologies. See Note 3 to the company's Consolidated Financial Statements for
the periods ended December 31, 1999 and 1998, entitled "Acquisition," for
further details. ATG also used approximately $2.7 million of cash during the six
months ended June 30, 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 (5.60% at December 31, 1999), 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 $16.0 million
as of December 31, 1999, 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

21
<PAGE>

$5 million. Borrowings, when made, bear a variable interest rate based on
certain financial ratio criteria. The credit facility is collateralized by
accounts receivable, inventory and equipment.

The credit facility agreement requires ATG to comply with certain
covenants, including capital asset acquisition limits, limits on additional
debt, minimum levels of tangible net worth, dividend payment restrictions and
maintenance of certain financial ratios. At December 31, 1999, ATG was in
violation of certain financial ratio covenants. ATG has obtained a 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 certain
financial ratio covenants that ATG failed to meet as of December 31, 1999, 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.

The company 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 the company 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, the company obtained a short-term loan in the amount of
$1,500,000 from an individual lender. The loan bears interest at a rate of 12%
per annum and is due on October 5, 2000. The company anticipates that it
will need to obtain additional financing or obtain an extension on the due
date in order to repay the loan.

As of September 20, 2000, 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. The company is continuing to negotiate with the
lenders to modify the financial covenants and the time frame for the mandatory
paydown. The company 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. The
company is also evaluating potential changes in its capital structure and
additional financial resources. We cannot assure you that we will be successful
in any of the foregoing endeavors. If ATG is unable to service its indebtedness,
the company may be required to alter its business plans, restructure or
refinance its indebtedness or seek additional equity capital. There can be no
assurance that we could accomplish these objectives on favorable terms, if at
all.

22
<PAGE>

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.

Recent Pronouncements

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 ("SFAS 133"), Accounting for Derivative
Instruments and Hedging Activities. SFAS 133 establishes accounting and
reporting standards requiring that every derivative instrument, including
certain derivative instruments embedded in other contracts, be recorded in the
balance sheet as either an asset or liability measured at its fair value. SFAS
133 requires that changes in the derivative's fair value be recognized currently
in earnings unless specific hedge accounting criteria are met. Special
accounting for qualifying hedges allows a derivative's gains and losses to
offset related results on the hedged item in the income statement, and requires
that a company must formally document, designate and assess the effectiveness of
transactions that receive hedge accounting. SFAS 133 is effective for ATG in
fiscal year 2000 and will not require retroactive restatement of prior period
financial statements. The adoption of SFAS 133 will not have a material impact
on our financial position and results of operations.

In December 1999, the Securities Exchange Commission ("SEC") issued Staff
Accounting Bulletin No. 101 ("SAB 101"), Revenue Recognition in Financial
Statements, which outlines the basic criteria that must be met to recognize
revenue and provides guidance for presentation of revenue and for disclosure
related to revenue recognition policies in financial statements filed with the
SEC. The adoption of the SAB 101 will not have a material impact on our
financial position and results of operations.

In March 2000, the FASB issued Interpretation No. 44, Accounting for
Certain Transactions Involving Stock Compensation - An Interpretation of APB 25
(the "Interpretation"). This Interpretation clarifies (a) the definition of an
employee for purposes of applying APB 25, (b) the criteria for determining
whether a stock plan qualifies as a non-compensatory plan, (c) the accounting
consequence of various modifications to the terms of a previously fixed stock
option or award, and (d) the accounting for an exchange of stock compensation
awards in a business combination. This Interpretation is effective July 1, 2000,
but certain conclusions in this Interpretation cover specific events that occur
after either December 15, 1998, or January 12, 2000. To the extent that this
Interpretation covers events occurring during the period after December 15,
1998, or January 12, 2000, but before the effective date of July 1, 2000, the
effects of applying this Interpretation are recognized on a prospective basis
from July 1, 2000. The Company does not believe the adoption of FIN 44 will have
a material impact on statement of operations.

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, 1999. 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 certain financial ratios applicable to the company 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 rate risk, and could be subjected to
increased interest payments if market interest rates fluctuate. An effective
increase or decrease of 10% in such interest rates would not have a material
adverse effect on our results of operations.

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
are presently anticipated to result in both substantial mixed waste revenue
starting in 2000 and to also 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

25
<PAGE>

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. Building upon the natural synergy between the
acquired business lines and our nuclear fixed facility business lines, in 1999
we integrated the assets acquired from Molten Metal Technologies with our
Richland, Washington waste processing operations. The integration permits
customer waste processing needs to be addressed and directed to the processing
location capable of providing the most efficient and economical treatment.

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;

. 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 industry sources, 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.

26
<PAGE>

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. Such 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. Such 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 such 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 such
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.

27
<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, 1999,
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 such 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., intends to provide
pyrolysis services for ion exchange resins but has yet to attain commercial
operating status.

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. The Department of
Energy, which owns most of those wastes, estimates that it 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. The Department of Energy also estimates that the total
treatment and disposal costs for its low-level radioactive waste will exceed one
billion dollars through the year 2010.

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

28
<PAGE>

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 is required to
commence non-thermal treatment of the low-level mixed waste stored there by
September 30, 1999, and thermal treatment of such waste by December 31, 2000.

Significant quantities of untreated low-level mixed waste have accumulated in
the United States, as approved treatment solutions applicable to a broad range
of such 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 survey study 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
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, financed, and is currently constructing 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.

ATG has already won a number of commercial and 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 such contract in December
of 1999. We anticipate that all of our mixed waste treatment service lines will
be operational during the year 2000 as the construction of our low-level mixed
waste facilities is currently proceeding on schedule.

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

30
<PAGE>

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.

CATALYTICS-Thermal Destruction of Ion Exchange Resins. Ion exchange resins
with significant radionuclide concentrations are destroyed in a patented and
licensed high temperature non-incineration process which provides high volume
and mass reductions similar to those provided by SAFGLAS(TM). The non-volatile
remains are encapsulated in a metal matrix for disposal.

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

31
<PAGE>

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. We believe the market for water treatment services
exceeds $100 million annually and that our AWPS system provides advantages that
will allow us to establish a major role in that market. One of our AWPS units
was installed in a commercial nuclear power plant in late 1999 and four pilot
units are already scheduled for installation and testing at commercial nuclear
power plants in 2000.

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

32
<PAGE>

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 such 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 complete until the early fall of
2000, we were able to successfully receive and process certain mixed wastes in
late 1999 and will continue to expand its mixed waste processing 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 will use a proprietary high temperature plasma
process to destroy RCRA and TSCA organic mixed wastes. That process, which the
company calls "GASVIT", will destroy 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 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 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

33
<PAGE>

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.

Field Engineering Group. The principal services provided by ATG's Field
Engineering Group are the environmental restoration of sites contaminated with
hazardous wastes and certain 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.

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, 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. There are over 420 Department of Defense sites contaminated with
low-level radioactive waste or low-level mixed waste. According to industry
sources, 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. 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 225 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. In addition, ATG is currently performing
under three Total Environmental Restoration Contracts with the U.S. Army Corps
of Engineers, two Pre-placed Remedial Action Contracts with the U.S. Army

34
<PAGE>

Corps of Engineers, two Remedial Action Contracts with the U.S. Navy and four
environmental restoration contracts with the Department of Energy, collectively
covering a 40 state area.

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.

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 such 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
operation in late 1997 and our acquisition of the assets of Molten Metal
Technologies in late 1998. In fiscal 1999, 1998, and 1997, the percentage of our
total revenue attributable to federal government contracts was approximately
27%, 55%, and 71%, 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. One contract
with the U.S. Army Corps of Engineers- Sacramento District accounted for 21% of
our total revenue in the year ended December 31, 1997. We also serve numerous
commercial clients, including large industrial concerns, nuclear power plants,
hospitals, laboratories and other medical institutions, and universities. A
substantial portion of our commercial work represents new contracts awarded by
existing clients. No single commercial client accounted for 10% or more of our
revenue in fiscal years 1999, 1998 or 1997.

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

35
<PAGE>

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 believe that these strategies have been validated by the
significant revenue growth we have experienced over the past three years.

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 such wastes, 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.
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 certain minimum
revenues are not achieved in those territories within specified periods.

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. 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

36
<PAGE>

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 such a facility, as most low-level radioactive
waste does not require treatment in order to meet the acceptance criteria of at
least one such 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 certain 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

37
<PAGE>

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 certain 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 such
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. 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. However, 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 certain 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) 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 such
patents. We routinely refer these letters of inquiry to such

38
<PAGE>

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 such letter of inquiry previously received by ATG,
we have been advised by the licensor that, in the judgement 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 such 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 expect that the amount of such expenditures required to be made
in 2000, particularly in connection with the construction of the mixed waste
facility to be sited at our Richland facilities, will be material.

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 certain exemptions. Under current regulations,
waste residues derived from listed hazardous wastes are generally considered to
be hazardous wastes subject to RCRA standards

39
<PAGE>

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 such facilities and upon parties who arranged
for the transportation of hazardous substances to such 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
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 certain 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

40
<PAGE>

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 such an 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. We presently anticipate to complete
our thermal demonstration testing and receive approval to become fully
operational during the fourth quarter of fiscal 2000.

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 June 30, 2000, ATG employed 350 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 June 30, 2000, 125 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.

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 Richland property is encumbered by a deed of trust securing our payment of
a $750,000 promissory note held by West One Bank. The West One note provides for
an interest rate of 8.75% during the first 42 months and an interest rate of
prime plus 2.75% (with a ceiling of 12% and a floor of 5.5%) during the final 42
months until maturity, 11.0% at June 30, 2000. The principal balance secured by
the deed of trust on the Richland property is approximately $20,000 as of
September 20, 2000.

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 September 20, 2000, the principal balance

42
<PAGE>

secured by the mortgage on the Oak Ridge property is approximately $379,000.
There are no encumbrances on ATG's Columbia or Aiken, South Carolina properties.

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

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 such 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. 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 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.

43
<PAGE>

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.

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
conducted seven (7) meetings during fiscal year 1999. All of the persons who
were directors immediately prior to the last annual shareholders' meeting held
on July 14, 2000 attended at least seventy-five percent (75%) of the aggregate
of: (i) the total number of meetings of the board of directors, and (ii) the
total number of meetings held by the committee(s) on which they served during
fiscal year 1999. 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 such 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

47
<PAGE>

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 such person first becomes a non-employee director, with 5,000 of
such 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. 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 certain 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 such change of control.

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 such 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.

52
<PAGE>

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 such 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 certain 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 such compensation or the annual limit prescribed by statute ($9,500 in
1997) and contribute the amount of such reduction to the 401(k) plan. The 401(k)
plan allows for matching contributions to the 401(k) Plan by ATG, such matching
and the amount of such matching to be determined at the sole discretion of the
Board. During 1999, ATG contributed $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.

LIMITATION ON DIRECTORS' LIABILITY

ATG's Articles of Incorporation provide that, pursuant to the California
Corporations Code, the liability of ATG's directors for monetary damages shall
be eliminated to the fullest extent permissible under California law. This is
intended to eliminate the personal liability of a director for monetary damages
in an action brought by, or in the right of, ATG for breach of a director's
duties to ATG or its shareholders. This provision in the Articles does not
eliminate the directors' fiduciary duty and does not apply to certain
liabilities:

. for acts or omissions that involve intentional misconduct or a knowing
and culpable violation of law;

. for acts or omissions that a director believes to be contrary to the best
interests of ATG or its shareholders or that involve the absence of good
faith on the part of the director;

. for any transaction from which a director derived an improper personal
benefit;

53
<PAGE>

. for acts or omissions that show a reckless disregard for the director's
duty to ATG or its shareholders in circumstances in which the director
was aware, or should have been aware, in the ordinary course of
performing a director's duties, of a risk of serious injury to ATG or its
shareholders;

. for acts or omissions that constitute an unexcused pattern of inattention
that amounts to an abdication of the director's duty to ATG or its
shareholders;

. with respect to certain transactions or the approval of transactions in
which a director has a material financial interest; and

. expressly imposed by statute for approval of certain improper
distributions to shareholders or certain loans or guarantees.

This provision also does not limit or eliminate the rights of ATG or any
shareholder to seek non-monetary relief such as an injunction or rescission in
the event of a breach of a director's duty of care.

The inclusion of the above provision in the Articles may have the effect of
reducing the likelihood of shareholder derivative suits against directors and
may discourage or deter shareholders or management from bringing a lawsuit
against directors for breach of their duty of care, even though such an action,
if successful, might otherwise have benefited ATG and its shareholders. ATG
believes that it is the position of the Securities and Exchange Commission that
insofar as the foregoing provision may be invoked to disclaim liability for
damages arising under the Securities Act if 1933, the provision is against
public policy as expressed in that act and is therefore unenforceable. ATG
believes that the foregoing provision of its Articles is necessary to attract
and retain qualified persons as directors.

COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934

Section 16(a) of the Securities Exchange Act of 1934 requires our directors
and executive officers, and persons who own more than ten percent (10%) of our
common stock, to file initial reports of ownership and reports of changes in
ownership with the Securities and Exchange Commission and the National
Association of Securities Dealers, Inc. Officers, directors and greater than
ten percent (10%) beneficial owners are required by the Securities and Exchange
Commission regulations to furnish us with copies of all Section 16(a) forms they
file. Specific due dates for these reports have been established and we are
required to disclose in this registration statement any late filings during the
most recent fiscal year. To our knowledge, based solely on its review of the
copies of such reports required to be furnished to us during the most recent
fiscal year, all of these reports were timely filed with the Securities and
Exchange Commission and the National Association of Securities Dealers, Inc.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

The following is a summary of certain transactions to which ATG was or is a
party and in which certain executive officers, directors or shareholders 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 1998.

Doreen M. Chiu and Frank Y. Chiu, the Executive Vice-President and a director
of ATG, have each guaranteed the obligations of ATG under (i) two promissory
notes in the principal amounts of $2,069,604 and $1,996,075 held by Safeco
Credit Company, Inc.; (ii) an equipment lease between ATG and Great Western
Leasing that provides for an aggregate rental amount of $32,522; and (iii) a
commercial lease agreement between ATG and U.S. Bancorp with an aggregate rental
amount of $103,341.

In connection with the issuance of certain bonds, undertakings and other
instruments of guarantee in favor of ATG, Doreen M. Chiu and Frank Y. Chiu have
each executed (i) a blanket indemnity agreement in favor of ACSTAR Insurance
Company, indemnifying ACSTAR against any losses that ACSTAR 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 Reliance Insurance Company, United Pacific
Insurance, Reliance National Indemnity Company and Reliance Surety Company,
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, 1999, the potential aggregate
liability of Mr. and Mrs. Chiu under the blanket indemnities was approximately
$35,500.

In 1998, ATG entered into a contract to provide certain 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
$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 $4,695,000 and is expected to be completed in
fiscal 2000.

PLAN OF DISTRIBUTION

The shares being offered by this prospectus will be offered and sold by the
selling shareholders named in this prospectus, by their donees or transferees,
or by their other successors in interest. ATG will not receive any of the
proceeds from the sale of the shares pursuant to this prospectus. ATG has agreed
to bear the expenses of the registration of the shares, including legal and
accounting fees, other than fees of counsel, if any, retained individually by
the selling shareholders, and any discounts or commissions payable with respect
to sales of the shares.

The selling shareholders may offer and sell the shares from time to time in
transactions in the over-the-counter market or in negotiated transactions, at
market prices prevailing at the time of sale or at negotiated prices. The
selling shareholders have advised ATG that they have not entered into any
agreements, understandings or arrangements with any underwriters or broker-
dealers regarding the sale of their shares, nor is there an underwriter or
coordinating broker acting in connection with the proposed sale of shares by the
selling shareholders. Sales may be made directly or to or through broker-
dealers who may receive compensation in the form of discounts, concessions or
commissions from the selling shareholders or the purchasers of shares for whom
such broker-dealers may act as agent or to whom they may sell as principal, or
both. Such compensation may be in excess of customary commissions.

From time to time, one or more of the selling shareholders may pledge or grant
a security interest in some or all of the shares owned by them. If the selling
shareholders default in performance of their secured obligations, the pledgees
or secured parties may offer and sell the shares from time to time by this
prospectus (except, in some cases, if the pledgees or secured parties are
broker-dealers or are affiliated with broker-dealers). The selling shareholders
also may transfer and donate shares in other circumstances. Transferees and
donees may also offer and sell the shares from time to time by this prospectus
(except, in some cases, if the transferees or donees are broker-dealers or are
affiliated with broker-dealers). The number of shares beneficially owned by
selling shareholders will decrease as and when the selling shareholders transfer
or donate their shares or default in performing obligations secured by their
shares. The plan of distribution for the shares offered and sold under this
prospectus will otherwise remain unchanged, except that the transferees, donees,
pledgees, other secured parties or other successors in interest will be selling
shareholders for purposes of this prospectus. If we are notified that a donee,
pledgee or other successor in interest of a selling shareholder intends to sell
more than 500 shares of our common stock, we will file a supplement to this
prospectus which includes all of the information required to be disclosed by
Item 507 of Regulation S-K. Further, ATG will file a post-effective amendment to
this registration statement upon any change in the plan of distribution.

The selling shareholders and any broker-dealers acting in connection with the
sale of the shares hereunder may be deemed to be "underwriters" within the
meaning of Section 2(11) of the Securities Act of 1933, and any commissions
received by them and any profit realized by them on the resale of the shares as
principals may be deemed underwriting compensation under the Securities Act of
1933.

59
<PAGE>

ATG has agreed to indemnify certain of the selling shareholders against
liabilities they may incur as a result of any untrue statement or alleged untrue
statement of any material fact in the registration statement of which this
prospectus forms a part, or any omission or alleged omission herein to state a
material fact necessary in order to make the statements herein not misleading.
Such indemnification includes liabilities that such selling shareholders may
incur under the Securities Act of 1933. ATG does not have to give such
indemnification if the untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with information
furnished in writing to ATG by the selling shareholder for use in the
registration statement.

ATG has advised the selling shareholders of (1) the requirement for delivery
of this prospectus in connection with any sale of the shares, and (2) the
relevant cooling off period specified by Regulation M and restrictions upon the
selling shareholders' bidding for or purchasing securities of ATG during the
distribution of shares.

DESCRIPTION OF SECURITIES

The following is a description of the capital stock of ATG and material
provisions of its articles of incorporation. The following is a summary and is
qualified in its entirety by the provisions of our articles of incorporation, as
amended, which have been filed as an exhibit to the registration statement of
which this prospectus is a part.

The authorized capital stock of the company currently consists of 50,000,000
shares consisting of 42,000,000 shares of common stock, no par value per share,
of which 16,867,678 shares are currently outstanding, and 8,000,000 shares of
preferred stock, of which no shares are currently outstanding. As of September
20, 2000, there were over 1800 record holders of our common stock.

Common Stock

The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the shareholders. The holders of
common stock are entitled to cumulative voting rights with respect to the
election of directors so long as at least one shareholder has given notice at
the meeting of shareholders prior to the voting of that shareholder's desire to
cumulate votes. Under cumulative voting, each shareholder may give any one
candidate whose name is placed in nomination prior to the commencement of voting
a number of votes equal to the number of directors to be elected, multiplied by
the number of votes to which the shareholder's shares are normally entitled, or
distribute such number of votes among as many candidates, in whatever
proportions, as the shareholder sees fit. The effect of cumulative voting is
that the holders of a majority of the outstanding shares of common stock may not
be able to elect all of ATG's directors. Subject to the rights of holders of any
preferred stock that may be outstanding, holders of common stock are entitled to
receive ratably such dividends as may be declared by the Board out of assets
legally available therefor at such times and in such amounts as the Board of
Directors may, from time to time, determine. See "Dividend Policy." In the event
of a liquidation, dissolution or winding up of ATG, subject to the rights of
holders of any preferred stock that may be outstanding, the holders of common
stock are entitled to share ratably in all assets of ATG remaining after payment
of liabilities and the liquidation preference of any then outstanding preferred
stock. Holders of common stock have no preemptive rights and no right to
convert their common stock into any other securities. There are no redemption or
sinking fund provisions applicable to the common stock. All outstanding shares
of common stock are fully paid and nonassessable.

Pursuant to the Common Stock Placement Agreement dated as of June 30, 2000
between ATG and the placement agent for the selling shareholders (the "Placement
Agreement"), ATG has agreed to prepare and file with the SEC, by no later than
August 21, 2000, the registration statement of which this prospectus forms a
part to register for resale the shares of common stock covered by this
prospectus (the "Registrable Securities"). ATG will use its best efforts to
have such registration statement declared effective as soon as possible after
filing, and to keep such registration statement current and effective until at
least July 7, 2003, or until such earlier date as all of the Registrable
Securities registered pursuant to this prospectus shall have been sold. If the

61
<PAGE>

registration statement of which this prospectus forms a part is not filed with
the SEC by August 21, 2000 or this registration statement shall not be declared
effective by November 4, 2000, then (i) with respect to the failure to file the
registration statement by August 21, 2000, the registered holders of such
Registrable Securities (including transferees authorized under applicable
securities laws; hereinafter, collectively the "Registered Holders") shall be
entitled at no cost to additional shares of common stock from ATG ("Additional
Shares") equal to the product of three (3%) percent of the number of Registrable
Securities owned by each such holder, and the number of thirty (30) day periods,
or any part thereof, beyond said forty-five (45) day period, until the initial
registration statement described herein covering the Registrable Securities is
filed with the SEC, and/or (ii) with respect to the registration statement not
being declared effective by November 4, 2000, the Registered Holders shall be
entitled at no cost to Additional Shares equal to the product of two (2%)
percent of the number of Registrable Securities owned by each such holder, and
the number of thirty (30) day periods, or any part thereof, beyond November 4,
2000, until the registration statement of which this prospectus forms a part
covering the Registrable Securities is declared effective. The maximum number
of Additional Shares issuable shall be thirty-six (36) percent. Holders of
common stock covered by this prospectus also have certain "piggy-back"
registration rights under the Placement Agreement.

PREFERRED STOCK

The following is a brief summary of the material rights, preferences,
privileges, restrictions and limitations of the outstanding shares of ATG's
preferred stock.

Under its Amended and Restated Articles of Incorporation, ATG is authorized to
issue 8,000,000 shares of "blank check" preferred stock. The Board of Directors
of ATG is authorized from time to time to provide by resolution for the issuance
of shares of preferred stock in one or more classes or series. The Board of
Directors of ATG is also authorized to designate, and to fix the number of
shares constituting, each such class or series; and to determine with respect to
each such class or series the voting powers, if any (which voting powers if
granted may be full or limited), designations, preferences and relative,
participating, optional or other special rights, and the qualifications,
limitations or restrictions applicable thereto, including, without limiting the
generality of the foregoing, the voting rights applicable to any class or series
(which may be any whole or fractional number of votes per share, and which may
be applicable generally or only upon stated matters, events or conditions); the
rate of dividend to which holders of preferred stock of any class or series may
be entitled (which may or may not be cumulative and/or participating); the
rights of holders of preferred stock of any class or series in the event of
liquidation, dissolution or winding up of the affairs of this corporation or
other circumstances; the rights, if any, of holders of preferred stock of any
class or series to convert or exchange such shares of preferred stock for shares
of any other class of capital stock of this corporation or any other entity or
to convert or exchange such preferred stock for any other form of property
(including in each case the determination of the price or prices or the rate or
rates applicable to such rights to convert or exchange and the adjustment
thereof, the time or times during which the right to convert or exchange shall
be applicable and the time or times during which a particular price or rate
shall be applicable); and the rights, if any, to redeem any class or series of
preferred stock (which may be mandatory at a fixed time or upon the occurrence
of a specified event, or may be optional on the part of this corporation and/or
the shareholder).

62
<PAGE>

Unless otherwise provided by law or in a resolution or resolutions
establishing a particular class or series of preferred stock, the aggregate
number of authorized shares of preferred stock may be increased by an amendment
to ATG's Amended and Restated Articles of Incorporation approved solely by the
holders of common stock and of any preferred stock which is entitled pursuant to
its voting rights designated by the Board to vote thereon, if at all, voting
together as a class.

The Board of Directors shall be entitled to increase or decrease the number of
shares previously designated by the Board to a class or series of preferred
stock without prior shareholder approval, provided that at no time shall the
Board of Directors be entitled to decrease the number of shares previously so
designated to a class or series to a number that is less than the number of
shares of such series then issued and outstanding.

Before ATG shall issue any shares of preferred stock of any class or series, a
certificate, setting forth a copy of the resolution or resolutions of the Board
of Directors, fixing the attributes of such class or series shall be filed in
the manner prescribed by the laws of the State of California.

OPTIONS AND WARRANTS

At September 20, 2000, options and warrants to purchase up to 1,686,000
shares of common stock, at a weighted average exercise price of $4.54 per share,
were outstanding, 897,000 of which were exercisable on such date.

TRANSFER AGENT AND REGISTRAR

The transfer agent and registrar for ATG's common stock is U.S. Stock Transfer
Corporation.

LEGAL MATTERS

Certain legal matters in connection with the issuance of the securities
offered hereby will be passed upon for ATG by Miller & Holguin, attorneys at
law, Los Angeles, California.

______________

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 tre atment of ion exchange resins, decontamination,
stabilization and volume reduction of low-level mixed waste, site remediation
and construction 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.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 9 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, which raises substantial doubt about its
ability to continue as a going concern if it cannot obtain additional cash to
repay the debt or restructure the debt. The financial statements do not include
any adjustments that might result from the outcome of this uncertainty.

The occurrence of an event of default permits 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 is negotiating with the lenders to modify the financial covenants and
the time frame for the mandatory paydown. In addition, ATG is reviewing
alternative forms of financing in order to meet comply with the credit facility
agreement. Management is reviewing the company's business plan with the
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.

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 generally recognized upon the substantial
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 of $1,975 was recognized pursuant to technology transfer
agreements in 1997.

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.

Disclosure of Significant Estimates - Revenue

As outlined in the Summary of Significant Accounting Policies - Revenue
Recognition, 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 an allocation for general and administrative
costs. 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.

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 twentyfive 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. As of December 31, 1999, management believes there is no impairment
with respect to these assets.

Risks and Uncertainties

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, 1999, management
believes that assets which could currently be affected by permitting efforts are
recoverable at their recorded values.

The market for the Company's services is substantially dependent on state
and federal legislation and regulations. The availability of new contracts
depends significantly on the regulatory environment. In order to build or retain
its market share the Company must continue to successfully compete for new
government and private sector contracts.

______________

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,
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. As of December 31, 1997, agencies of the U.S.
government represented 47% of accounts receivable and 71% of total revenue for
the year then ended. The Company generally does not require collateral.

Computation of Net Income Per Share

Basic income per share is computed by dividing income 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.

Recent Pronouncements

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 ("SFAS 133"), Accounting for Derivative
Instruments and Hedging Activities. SFAS 133 establishes methods of accounting
for derivative financial instruments and hedging activities related to those
instruments as well as other hedging activities, and is effective for fiscal
years beginning after June 15, 2000, as amended by SFAS No. 137.

______________

The adoption of this pronouncement will have no material impact on the Company's
financial position and results of operations.

In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101 ("SAB 101"), Revenue Recognition in Financial
Statements, which outlines the basic criteria that must be met to recognize
revenue and provides guidance for presentation of revenue and for disclosure
related to revenue recognition policies in financial statements filed with the
SEC. The adoption of SAB 101 will not have a material impact on the Company's
financial position and results of operations.

Comprehensive Income

In the first quarter of 1998 the Company adopted Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income," which
specifies the computation, presentation and disclosure requirements for
comprehensive income. There was no impact on the Company's financial position,
results of operations or cash flows as a result of adoption. Comprehensive
income and net income are the same.

3. 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 throught 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 assets
acquired and will be amortized over the lives of those assets. During 1999 the
final purchase price allocation was concluded and as result the purchase price
allocation was revised as follows:

</TABLE>

The value of property and equipment was increased by $6.8 million, not to
exceed its fair market value (FMV) appraisal of $22.2 million. The Company
recorded $1.4 million in goodwill which is the amount of increase in accrued
liabilities of $8.2 million less the increase of $6.8 million in property and
equipment value from the FMV appraisal. The accrued liabilities adjustment was
primarily due to waste processing and disposal costs associated with waste
materials on site at the time of the acquisition. As of December 31, 1999, the
Company has accrued $5.2 million for the future cost of waste processing and
disposal for waste materials on site at the time of the acquisition.

Mixed Waste Facility

During 1999, construction of the Company's new mixed waste treatment
facility in Richland, Washington was begun resulting in a significant increase
in construction in progress over the prior year. The facility began operations
in some treatment lines in late 1999. The facility is financed by the issuance
of $26.5 million of tax-exempt Solid Waste Revenue Bonds. See Note 9 - Borrowing

term debt at December 31, 1999.

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 $4,695 of which revenues of $1,403 and $785 were recognized in 1999 and 1998
respectively. Costs of $1,354 and $482 in 1999 and 1998, respectively, are
associated with this project. The related accounts receivable include $857 and
$785 at December 31, 1999 and 1998, 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 (5.60% at December 31, 1999), 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 $16.0 million as of December
31, 1999, 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 Company currently has borrowings of $17.5 million
and qualifies for the Banks' reference rate of 9.25%. 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 net worth, dividend payment restrictions and
maintenance of certain financial ratios. At December 31, 1999 the Company was
in violation of certain financial ratio covenants. The Company has obtained a
waiver, subsequent to year-end, in respect of these violations as of

F-14
<PAGE>

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

_____________

December 31, 1999. In connection with the waiver, the Banks agreed to revise and
lower certain financial ratio covenants that the Company failed to meet as of
December 31, 1999, for each of the quarterly periods in the year ended December
31, 2000, and increase the borrowings available to the Company 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 until no
later than 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 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.

Under a short term line of credit facility with a bank, the Company may
borrow up to $1.9 million. Borrowings under this credit agreement were $1.7
million at December 31, 1999, bear interest equal to the bank's reference rate
(9.25% at December 31, 1999) and are secured by the Company's Fremont, CA
building property.

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 annual rates between 8.125% and 11.0%, matures between 2001 and
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 1999
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 9.6%, mature between 1999 and 2002, and are
collateralized by specific equipment.

Future minimum principal payments are as follows as of December 31, 1999:

10. Commitments and Contingencies

In June 1992, the Company entered into a contract with the U.S. Army under
which the Company acted as the prime contractor to "surface clear" expended
ordnance from a firing range at Fort Irwin, California (the "Fort Irwin
Contract"). In March 1997, a piece of ordnance exploded on the premises of a
scrap metal dealer (the "Scrap 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 the Company on the Fort Irwin Contract (the "Subcontractor")
had improperly certified ordnance cleared from the Fort Irwin firing range as
free of hazardous and explosive material prior to the sale of such ordnance to
the Scrap Dealer. As a result, the U.S. Army terminated the Fort Irwin Contract
for default, and demanded repayment from the Company of alleged reprocurement
costs totaling $945,000. The Company 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 the Company
settled the matter. The termination for default was rescinded and the Company
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 the Company, 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 Company has tendered the defense of each of
these actions to its insurance carrier, which is presently handling the matters
for the Company, and the Company intends to vigorously contest all of the claims
asserted in these actions. The Company believes that it acted properly with
respect to the Fort Irwin Contract, and that it should not be liable for the
injuries caused by the accident. The Company also intends to seek
indemnification from the Subcontractor for the full amount of any costs, damages
and liabilities which may be incurred by the Company in connection with or as a
result of these lawsuits. The Subcontractor has advised the Company that

F-16
<PAGE>

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

_____________

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 the Company believes that all of the claims
asserted against the Company are without legal merit, the outcome of these
lawsuits is uncertain. Any judgment of liability against the Company, especially
to the extent damages exceed or are not covered by insurance or are not
recoverable by the Company from the Subcontractor, could have a material adverse
effect on the Company's business, financial condition and results of operations.

From time to time the Company is a party to litigation or administrative
proceedings relating to claims arising from its operations in the normal course
of business. Management of the Company, on the advice of counsel, believes that
the ultimate resolution of litigation currently pending against the Company is
unlikely, either individually or in the aggregate, to have a material adverse
effect on the Company's 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 500,000 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

As of December 31, 1999, options to purchase 501,120 shares of Common Stock
at $0.01 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 $120 and $120 have been amortized during the years ended
December 31, 1999 and 1998, respectively, and is included in the statement of
operations within the caption "Stock-based compensation expense".

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

Employee Stock Purchase Plan ("Purchase Plan")

A total of 200,000 shares of common stock are reserved for issuance under
the Purchase Plan. The Purchase Plan enables eligible employees to purchase
common stock at the lower of 85% of the fair market value of the Company's
common stock on the first or last day of each six-month offering period. The
total shares purchased under the plan during 1999 and 1998, were 15,000 and
4,000 respectively.

12. Common Stock Warrants

Warrants to purchase 190,000 shares of Common Stock were granted upon the

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 1999, the Company contributed $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 and 1997.

16. SALE OF CORPORATE FACILITIES

The Company has sold to a less than 1% shareholder of the Company, the
Company's facility, building and land, located in Fremont California. The
Company has transferred title to the building to the new owner on December 10,
1999. The terms of the sale agreement includes a 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
F-22

__________

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 has "continuing involvement" with the building subsequent to the
sale and remains 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 is deferred pending termination
of its continued involvement. The deposit payment of $810 has been included
within the balance sheet caption, "accrued liabilities" as of December 31, 1999.
The Company will continue to depreciate the building and account for the
building asset and debt as if owned by the Company. The Company will apply the
provisions of sale and leaseback accounting to the transaction after the Company
no longer has any "continuing involvement" with the building as defined by
generally accepted accounting principles.

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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
June 30, 2000
(Unaudited)

1. 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 throughout the United States. Services principally consist of
compaction, reduction, decontamination, vitrification and disposal of low-level
dry active nuclear, hazardous, and mixed wastes, dewatering and thermal
treatment of ion exchange resins and site remediation and construction projects.

The accompanying condensed consolidated financial statements include the
accounts of the Company and its wholly owned and majority owned subsidiaries.
The condensed consolidated financial statements included herein have been
prepared by the Company, without audit, pursuant to the rules and regulations of
the Securities and Exchange Commission. Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted
pursuant to such rules and regulations. These condensed consolidated financial
statements should be read in conjunction with the consolidated financial
statements and the notes thereto included in the Company's Annual Report on Form
10-K and Form 10-K/A for the year ended December 31, 1999 and the Audited
Consolidated Financial Statements included therein.

The unaudited condensed consolidated financial statements included herein
reflect all adjustments (which include only normal, recurring adjustments) which
are, in the opinion of management, necessary to state fairly, in all material
respects, the financial position, results of operations and cash flows for the
six months ended June 30, 2000 and 1999. The preparation of financial statements
in conformity with generally accepted accounting principles requires management
to make estimates and assumptions that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ materially from those
estimates. The results for the six months ended June 30, 2000 are not
necessarily indicative of the results for the full fiscal year.

2. NET INCOME PER SHARE

Basic net income per share is computed by dividing net income by the weighted
average number of common shares outstanding for the period. Diluted net income
per share is computed giving effect to all dilutive potential common shares that
were outstanding during the period. Dilutive potential common shares consist of
the incremental common shares issuable upon the exercise of stock options for
all periods.

A reconciliation of the numerator and denominator of basic and diluted net
income per share is provided as follows (in thousands, except per share data):

4. RECENT PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 ("SFAS 133"), Accounting for Derivative
Instruments and Hedging Activities. SFAS 133 establishes methods of accounting
for derivative financial instruments and hedging activities related to those
instruments as well as other hedging activities, and is effective for fiscal
years beginning after June 15, 2000, as amended by SFAS No. 137. The adoption of
this pronouncement will have no material impact on the Company's financial
position and results of operations.

In December 1999, the Securities and Exchange Commission ("SEC") issued Staff
Accounting Bulletin No. 101 ("SAB 101"), Revenue Recognition in Financial
Statements, which outlines the basic criteria that must be met to recognize
revenue and provides guidance for presentation of revenue and for disclosure
related to revenue recognition policies in financial statements filed with the
SEC. The adoption of SAB 101 will not have a material impact on the Company's
financial position and results of operations.

5. COMMITMENTS AND CONTINGENCIES

In June 1992, the Company entered into a contract with the U.S. Army under which
the Company acted as the prime contractor to "surface clear" expended ordnance
from a firing range at Fort Irwin, California (the "Fort Irwin Contract"). In
March 1997, a piece of ordnance exploded on the premises of a scrap metal dealer
(the "Scrap 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 the
Company on the Fort Irwin Contract (the "Subcontractor") had improperly
certified ordnance cleared from the Fort Irwin firing range as free of hazardous
and explosive material prior to the sale of such ordnance to the Scrap Dealer.
As a result, the U.S. Army terminated the Fort Irwin Contract for default, and
demanded repayment from the Company of alleged reprocurement costs totaling
$945,000. The Company 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 the Company settled the
matter. The termination for default was rescinded and the Company agreed to no
longer bid on surface- clearing work at active U.S. Army firing ranges.

F-31
<PAGE>

physical injuries and emotional distress caused by the accident. The Company has
tendered the defense of each of these actions to its insurance carrier, which is
presently handling the matters for the Company, and the Company intends to
vigorously contest all of the claims asserted in these actions. The Company
believes that it acted properly with respect to the Fort Irwin Contract, and
that it should not be liable for the injuries caused by the accident. The
Company also intends to seek indemnification from the Subcontractor for the full
amount of any costs, damages and liabilities which may be incurred by the
Company in connection with or as a result of these lawsuits. The Subcontractor
has advised the Company 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 the Company
believes that all of the claims asserted against the Company are without legal
merit, the outcome of these lawsuits is uncertain. Any judgment of liability
against the Company, especially to the extent damages exceed or are not covered
by insurance or are not recoverable by the Company from the Subcontractor, could
have a material adverse effect on the Company's business, financial condition
and results of operations.

6. SUBSEQUENT EVENTS

Restructuring Charge.

During the quarter ended June 30, 2000, the Company announced and completed a
restructuring plan, which included a workforce reduction of approximately 110
employees. The plan was primarily aimed at improving cost efficiencies and
waste processing processes. The Company recorded a total charge of $ 2.4
million which included non cash charges of $800,000 for equipment taken out of
service and $500,000 for a write-down of the maintenance supply inventory. The
restructuring charge also included charges of $692,000 for severance costs and
$408,000 for plant consolidation costs, of which $698,000 remains unpaid at June
30, 2000.

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 13. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

The following table sets forth an itemized statement of all expenses to be
incurred in connection with the issuance and distribution of the securities that
are the subject of this registration statement other than underwriting discounts
and commissions. All expenses incurred with respect to the distribution will be
paid by ATG, and such amounts, other than the Securities and Exchange Commission
registration fee, are estimates only.

Securities and Exchange Commission registration fee $ 1,844.95
Printing expenses 5,000.00
Legal fees and expenses 25,000.00
Accounting fees and expenses 10,000.00
Other expenses 0.00

Total $41,844.95

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

ATG's Articles of Incorporation provide that, pursuant to the California
Corporations Code, the liability of the directors of the company for monetary
damages shall be eliminated to the fullest extent permissible under California
law. This is intended to eliminate the personal liability of a director for
monetary damages in an action brought by, or in the right of, the company for
breach of a director's duties to the company or its shareholders. This provision
in the Articles does not eliminate the directors' fiduciary duty and does not
apply for certain liabilities: (i) for acts or omissions that involve
intentional misconduct or a knowing and culpable violation of law; (ii) for acts
or omissions that a director believes to be contrary to the best interests of
ATG or its shareholders or that involve the absence of good faith on the part of
the director; (iii) for any transaction from which a director derived an
improper personal benefit; (iv) for acts or omissions that show a reckless
disregard for the director's duty to ATG or its shareholders in circumstances in
which the director was aware, or should have been aware, in the ordinary course
of performing a director's duties, of a risk of serious injury to ATG or its
shareholders; (v) for acts or omissions that constitute an unexcused pattern of
inattention that amounts to an abdication of the director's duty to the company
or its shareholders; (vi) with respect to certain transactions or the approval
of transactions in which a director has a material financial interest; and (vii)
expressly imposed by statute for approval of certain improper distributions to
shareholders or certain loans or guarantees. This provision also does not limit
or eliminate the rights of the company or any shareholder to seek non-monetary
relief such as an injunction or rescission in the event of a breach of a
director's duty of care.

Section 317 of the California Corporations Code provides that a California
corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened,

II-1

<PAGE>

pending or completed action or proceeding, whether civil, criminal,
administrative or investigative (other than action by or in the right of the
corporation) by reason of the fact that he is or was a director, officer,
employee, or agent of the corporation or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation or
enterprise, against expenses, judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation, and, with respect
to any criminal action or proceeding, had no cause to believe his conduct was
unlawful.

Section 317 also provides that a California corporation may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses actually
and reasonably incurred by him in connection with the defense or settlement of
such action or suit if he acted under similar standards, except that no
indemnification may be made in respect to any claim, issue or matter as to which
such person shall have been adjudged to be liable to the corporation unless and
only to the extent that the court in which such action or suit was brought shall
determine that despite the adjudication of liability, such person is fairly and
reasonably entitled to be indemnified for such expenses which the court shall
deem proper.

Section 317 provides further that to the extent a director or officer of a
California corporation has been successful in the defense of any action, suit or
proceeding referred to in the previous paragraphs or in the defense of any
claim, issue or matter therein, he shall be indemnified against expenses
actually and reasonably incurred by him in connection therewith; that
indemnification authorized by Section 317 shall not be deemed exclusive of any
other rights to which the indemnified party may be entitled; and that the
corporation may purchase and maintain insurance on behalf of a director or
officer of the corporation against any liability asserted against him or
incurred by him in any such capacity or arising out of his status as such
whether or not the corporation would have the power to indemnify him against
such liabilities under Section 317.

ATG believes that it is the position of the Commission that insofar as any of
the foregoing provisions may be invoked to disclaim liability for damages
arising under the Securities Act, the provision is against public policy as
expressed in the Securities Act and is therefore unenforceable. Such limitation
of liability also does not affect the availability of equitable remedies such as
injunctive relief or rescission.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

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. On June 30, 2000, the
company 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, the company 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 to the
placement agent or its designees warrants to purchase a total of 192,500 shares
of common stock. The

II-2
<PAGE>

warrants are exercisable at a price of $2.75 per share, subject to adjustment
for certain events, and expire on June 30, 2005.

The company believes that the issuances of common stock and warrants described
above were exempt from the registration requirements of the Securities Act by
virtue of Section 4(2) thereof and Rule 506 of Regulation D thereunder, and by
virtue of Section 4(6) thereof. Private investors were contacted without any
general advertising or general solicitation. Each investor represented to the
company that it was an accredited investor and was acquiring the securities for
investment and without a view to distribution. The securities were issued
subject to legend condition. Investors were provided with disclosure about the
company and were given the opportunity to ask questions of and receive answers
from the company prior to investing.

Item 17. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the
Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most
recent post-effective amendment thereof) which, individually or
in the aggregate, represent a fundamental change in the
information set forth in the registration statement.
Notwithstanding the foregoing, any increase or decrease in
volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered)
and any deviation from the low or high end of the estimated
maximum offering range may be reflected in the form of
prospectus filed with the Commission pursuant to Rule 424(b) if,
in the aggregate, the changes in volume and price represent no
more than a 20% change in the maximum aggregate offering price
set forth in the "Calculation of Registration Fee" table in the
effective registration statement; and

(iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration
statement or any material change to such information in the
registration statement;

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

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

(h) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment
by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in

II-7

<PAGE>

the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the
securities being registered, the registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to
a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
