                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information, including "Risk Factors" and the Company's Consolidated Financial
Statements and the Notes thereto, appearing elsewhere in this Prospectus.
                                   
                                THE COMPANY     
 
  The Company, founded in 1976, is a radioactive and hazardous waste management
company that offers comprehensive treatment solutions for low-level radioactive
waste ("LLRW") and low-level mixed waste ("LLMW") generated by the U.S.
Department of Defense ("DOD") and U.S. Department of Energy ("DOE"), as well as
commercial entities, such as nuclear power plants, medical facilities and
research institutions. The Company's thermal treatment technologies vitrify
waste into leach-resistant glass for long-term storage or disposal. Compared
with the more traditional incineration methods, the Company's vitrification
process results in significantly less effluents, provides a more stable end
product and achieves comparable volume and mass reduction at similar total
treatment and disposal costs.
 
  The Company's growth strategy is to: (i) increase its share of the domestic
commercial LLRW treatment market; (ii) establish a significant position in the
emerging domestic LLMW treatment market; (iii) increase its participation in
large-scale domestic and international waste clean-up projects; (iv) expand
into selected Pacific Rim markets; and (v) enhance its on-site waste treatment
capabilities.
   
  The Company operates one of only two commercial facilities in the United
States licensed to thermally treat a broad spectrum of LLRW, and is the only
company in the United States licensed to vitrify both commercial and
government-generated LLRW. Since 1988, the Company has treated several million
pounds of LLRW, over 150,000 pounds of which have been treated since September
1997 using the Company's SAFGLAS vitrification system. In the first quarter of
1998, the Company entered into service agreements with an additional seven
nuclear utilities, covering an additional fifteen nuclear power plants, to
accept and treat LLRW generated by such utilities.     
   
  In 1994, the Company commenced the licensing process for its Richland,
Washington facilities to treat LLMW, which is LLRW mixed with hazardous
constituents. The Company believes it will receive final approval in 1998 for
full-scale thermal and non-thermal LLMW processing, which is anticipated to
begin in 1999. The Company believes that its mixed waste treatment facility
will be the first privately owned facility in the United States licensed to
thermally and non-thermally treat a broad spectrum of commercial and
government-generated LLMW.     
 
  The Company operates through its Fixed Facilities Group, which manages its
waste treatment operations, and its Field Engineering Group, which addresses
on-site decontamination and decommissioning of radioactive facilities ("D&D")
and environmental restoration of sites contaminated with radioactive and
hazardous waste. Historically, a majority of the Company's revenue has been
derived from on-site services. The Company has completed over 150 environmental
restoration projects since 1989 and provided D&D services for over a decade.
The synergies between the on-site remediation services of its Field Engineering
Group and the waste treatment operations of its Fixed Facilities Group enhance
the Company's ability to compete for commercial and government LLRW and LLMW
treatment contracts.
 
  In the last three years, the Company has formed teaming relationships with,
among others, Lockheed Martin Corporation ("Lockheed Martin"), Morrison Knudsen
Corporation ("Morrison Knudsen") and Jacobs Engineering Group Inc. ("Jacobs
Engineering") to pursue large contract awards requiring diverse waste
management and treatment expertise. The Company intends to continue to enter
into such relationships and is currently in the early stage of pursuing similar
strategic alliances with foreign entities in selected Pacific Rim markets with
established LLRW or LLMW clean-up initiatives or where scarcity of land and
high disposal costs create an opportunity for vitrification treatment
technologies.
 
  The Company 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. Its principal executive offices are located at 47375 Fremont
Boulevard, Fremont, California 94538, and its telephone number is: (510) 490-
3008.

                                 RISK FACTORS
 
  In addition to the other information set forth in this Prospectus, investors
should carefully consider the following risk factors when evaluating the
Company and its business before purchasing shares of the Common Stock offered
hereby.
 
DEPENDENCE ON GOVERNMENT LICENSES, PERMITS AND APPROVALS
 
  The radioactive and hazardous waste management industry is highly regulated.
The Company is required to have federal, state and local governmental
licenses, permits and approvals for its waste treatment facilities and
services. Such licenses, permits or approvals are subject to denial,
revocation or modification under a variety of circumstances. Failure to
obtain, or to comply with the conditions of, applicable licenses, permits or
approvals could adversely affect the Company's business, financial condition
and results of operations. As its business expands and as it introduces new
technologies, the Company will be required to obtain additional operating
licenses, permits or approvals. It may be required to obtain additional
operating licenses, permits or approvals if new environmental legislation or
regulations are enacted or promulgated or existing legislation or regulations
are amended, re-interpreted or enforced differently than in the past. Any new
requirements which raise compliance standards may require the Company to
modify its waste treatment technologies to conform to more stringent
regulatory requirements. There can be no assurance that the Company will be
able to continue to comply with all of the environmental and other regulatory
requirements applicable to its business. See "Business--Environmental Laws and
Regulations; Licensing Processes Applicable to LLRW and LLMW Treatment
Facilities."
 
NO ASSURANCE OF SUCCESSFUL DEVELOPMENT, COMMERCIALIZATION OR ACCEPTANCE OF
TECHNOLOGIES
   
  The Company is in the process of developing, refining and implementing its
technologies for the treatment of LLRW, LLMW and other wastes. The Company's
future growth will be dependent in part upon the acceptance and implementation
of these technologies, particularly its recently developed vitrification
technologies for the treatment of LLRW and LLMW. There can be no assurance
that successful development of all these technologies will occur in the near
future, or even if successfully developed, that the Company will be able to
successfully commercialize such technologies. The successful commercialization
of the Company's vitrification technologies may depend in part on ongoing
comparisons with other competing technologies and more traditional treatment,
storage and disposal alternatives, as well as the continuing high cost and
limited availability of commercial disposal options. There can be no assurance
that the Company's vitrification and related technologies will prove to be
commercially viable or cost-effective, or if commercially viable and cost-
effective, that the Company will be successful in timely securing the
requisite regulatory licenses, permits and approvals for such technologies or
that such technologies will be selected for use in future waste treatment
projects. The Company's LLMW thermal treatment contract with the DOE's-Hanford
Reservation requires the Company to obtain all of the required licenses,
permits and approvals for, and to build and place in operation, its LLMW
treatment facility by December 31, 1999. The Company's inability to develop,
commercialize or secure the requisite licenses, permits and approvals for its
waste treatment technologies on a timely basis could have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Business--Waste Treatment Technologies."     
 
DEPENDENCE ON ENVIRONMENTAL LAWS AND REGULATIONS
 
  A substantial portion of the Company's revenue is 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 the
services offered by the Company. The level of enforcement activities by
federal, state and local environmental protection agencies and changes in such
laws and regulations also affect the demand for such 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 LLRW, LLMW or other wastes, the demand for
the Company's services, and its business, financial condition and results of
operations, could be materially adversely affected.
 
                                       6
<PAGE>
 
See "Business--Environmental Laws and Regulations; Licensing Processes
Applicable to LLRW and LLMW Treatment Facilities."
 
DEPENDENCE ON FEDERAL GOVERNMENT; LIMITS ON GOVERNMENT SPENDING; GOVERNMENT
CONTRACTING
 
  For the fiscal years ended December 31, 1995, 1996 and 1997, approximately
86.3%, 76.8% and 71.3%, respectively, of the Company's total revenue was
derived from federal government contracts. The Company expects that the
percentage of its revenue attributable to such contracts will continue to be
substantial for the foreseeable future. The Company's government contracts
generally are subject to cancellation, delay or modification at the sole
option of the government. See "Management's Discussion and Analysis of
Financial Conditions and Results of Operations" and "Business--Customers."
 
  The Company is dependent on government appropriations to fund many of its
contracts. Efforts to reduce the federal budget deficit could adversely affect
the availability and timing of government funding for the clean-up of DOE, DOD
and other federal government sites. The failure by the government to fund
future restoration of such sites could have an adverse effect on the Company's
business, financial condition and results of operations. In addition, the
taxing authority of the Comprehensive Environmental Response, Compensation and
Liability Act of 1980 ("CERCLA" or "Superfund") has expired. Although bills to
reauthorize Superfund were introduced in Congress in late calendar 1997 and
action is anticipated in 1998, the potential for further delay could adversely
affect the environmental remediation industry. See "Business--Environmental
Laws and Regulations; Licensing Processes Applicable to LLRW and LLMW
Treatment Facilities."
 
  As a provider of services to federal and other government agencies, the
Company also faces risks associated with government contracting, which include
substantial fines and penalties for, among other matters, 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 its government contracting
business, the Company has been, and expects to be in the future, the subject
of audits, and may in the future be subject to investigations, by government
agencies. Failure to comply with the terms of one or more of its government
contracts could result in damage to the Company's business reputation and the
Company's suspension or disqualification from future government contract
projects for a significant period of time. The fines and penalties which could
result from noncompliance with applicable standards and regulations, or the
Company's suspension or disqualification, could have a material adverse effect
on the Company's business, financial condition and results of operations. See
"Business--Environmental Contractor Risks."
   
NEED FOR ADDITIONAL CAPITAL     
   
  In addition to the proceeds from the Offering, the Company believes that it
will need additional capital in order to implement its long-term growth
strategy. There can be no assurance that the Company will be successful in
raising the requisite amount of capital when needed, or, that if successful,
the terms of the financing will be favorable to the Company. In the event that
such financing is effected through the sale of shares of the Common Stock, or
securities convertible into such shares, the percentage ownership of the
Company's then shareholders will be diluted proportionately. If the Company is
not successful in raising such additional capital, it will need to curtail or
scale back its planned expansion, which could adversely affect the Company's
business, financial condition and results of operations. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources" and "Business--Growth Strategy."     
 
SEASONALITY AND FLUCTUATION IN QUARTERLY RESULTS
   
  The Company's revenue is dependent on its 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
the Company's customers have tended to ship waste during the months in which
transportation is less likely to be adversely affected by weather conditions.
The Company's revenue is also affected by the timing     
 
                                       7
<PAGE>
 
   
of its 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, the Company's quarterly results fluctuate.
Accordingly, specific quarterly or interim results should not be considered
indicative of results to be expected for any future quarter or for the full
year. Due to the foregoing factors, it is possible that in future quarters the
Company's operating results will not meet the expectations of securities
analysts and investors. In such event, the price of the Common Stock could be
materially adversely affected. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Quarterly Operating Results."
    
MANAGEMENT OF GROWTH
 
  Since 1994, the Company has experienced significant growth, attributable in
large part to an increase in the number and size of contracts awarded. The
Company is currently pursuing a growth strategy intended to expand its business
domestically and internationally. The Company's historical growth has placed,
and any future growth may place, significant demands on its operational,
managerial and financial resources. There can be no assurance that the
Company's current management and systems will be adequate to address any future
expansion of the Company's business. In such event, any inability to manage the
Company's growth effectively could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
EQUIPMENT PERFORMANCE; SAFETY AND LICENSE VIOLATIONS
 
  The Company's ability to perform under current waste treatment contracts and
to successfully bid for future contracts is dependent upon the consistent
performance of its waste treatment systems at its fixed facilities in
conformity with safety and other requirements of the licenses under which the
Company operates. The Company's fixed facilities are subject to frequent
routine inspections by the regulatory authorities issuing such licenses. In the
event that any of the Company's 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 the Company operates, the
Company's business, financial condition and results of operations could be
materially adversely affected. See "Business--Waste Treatment Technologies" and
"--Operations and Services."
 
ENVIRONMENTAL CONTRACTOR AND REGULATORY MATTERS
 
  The rapidly developing and changing regulatory framework governing the
Company's business creates significant risks, including potential liabilities
from violations of environmental statutes and regulations and liabilities to
customers and third parties for damages arising from services performed. The
Company's failure to comply with such statutes and regulations, or with the
terms and conditions of licenses and permits it holds under these and other
statutes and regulations, may result in the imposition of substantial fines and
penalties and could adversely affect the Company's ability to carry on its
business as presently constituted. In performing services, the Company could
potentially be liable for claims brought by its customers for breach of
contract, personal injury, property damage, and negligence, including claims
for lack of timely performance or for failure to deliver the service promised
(including improper or negligent performance or design, failure to meet
specifications, and breaches of express or implied warranties). The damages
available to a customer, should it prevail in its claims, are potentially large
and could include consequential damages. The Company's potential liability is
amplified by the increasing tendency to attempt to shift various liabilities
arising out of remediation of environmental contamination to contractors
through contractual indemnities, such as provisions seeking to require the
contractor to assume liabilities for damage or injury to third parties and
property and for environmental fines and penalties. Radioactive and hazardous
waste management contractors also potentially face liabilities to third parties
from various claims, including claims for property damage, personal injury or
wrongful death stemming from a release of radioactive or hazardous substances,
improper handling of explosives and other hazardous materials, or otherwise. In
addition, increasing numbers of claimants assert that companies performing
radioactive and hazardous waste management services should be adjudged strictly
liable (i.e., liable for damages even though their services were performed
using reasonable care), on the grounds that such services involved "abnormally
dangerous activities." The Company has adopted a range of risk management
programs designed to reduce these
 
                                       8
<PAGE>
 
   
risks and potential liabilities, including policies to seek contractual
indemnities, other contract administration procedures, and employee health,
safety, training and environmental monitoring programs; however, there can be
no assurance that such programs will protect the Company from such risks and
liabilities. See "Business--Environmental Contractor Risks," "--Operations and
Services" and "--Risk Management and Insurance."     
 
COMPETITION
 
  In general, the market for radioactive and hazardous waste management
services is highly competitive. The Company faces competition in its 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 the Company's competitors have
greater financial, managerial, technical and marketing resources than the
Company. To the extent that competitors possess or develop superior or more
cost-effective waste treatment solutions or field service capabilities, or
otherwise possess or acquire competitive advantages compared to the Company,
the Company's ability to compete effectively could be materially adversely
affected. Any increase in the number of licensed commercial LLRW treatment
facilities or disposal sites in the United States or any decrease in the
treatment or disposal fees charged by such facilities or sites could increase
the competition faced by the Company or reduce the competitive advantage of
certain of the Company's treatment technologies. See "Business--Market
Overview" and "--Competition."
 
INTERNATIONAL EXPANSION
   
  A key component of the Company's long-term growth strategy is to expand its
business into selected Pacific Rim markets. There can be no assurance that the
Company or its strategic alliance partners will be able to market its
technologies or services successfully in foreign markets. In addition, there
are certain risks inherent in foreign operations, including general economic
conditions in each country, varying regulations applicable to the Company's
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. In
particular, recent economic instability in certain Pacific Rim countries could
substantially impede the Company's targeted expansion into that region. In
such event, the Company's business, financial condition and results of
operations could be materially adversely affected. There can be no assurance
that laws or administrative practices relating to taxation, foreign exchange
or other matters of foreign countries within which the Company operates or
will operate will not change. Any such change could have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Business--Growth Strategy."     
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company's future success depends on its continuing ability to attract,
retain and motivate highly qualified managerial, technical and marketing
personnel. The Company is highly dependent upon the continuing contributions
of its key managerial, technical and marketing personnel. The Company's
employees may voluntarily terminate their employment with the Company at any
time, and competition for qualified technical personnel, in particular, is
intense. The loss of the services of any of the Company's managerial,
technical or marketing personnel could materially adversely affect the
Company's business, financial condition and results of operations. The Company
maintains a $1.5 million key man life insurance policy on the life of each of
Doreen M. Chiu and Frank Y. Chiu. There can be no assurance that such amount
will be sufficient to compensate the Company for the loss of the services of
these individuals. See "Business--Employees" and "Management."
 
FOCUS ON LARGER PROJECTS
 
  The Company 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
 
                                       9
<PAGE>
 
bid. A loss on one or more of such larger contracts could have a material
adverse effect on the business, financial condition and results of operations
of the Company. In addition, failure to obtain, or delay in obtaining,
targeted large, multi-year contracts could result in significantly less
revenue to the Company than anticipated. See "Business--Customers," "--Sales
and Marketing" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Overview."
 
POTENTIAL ENVIRONMENTAL LIABILITY AND INSURANCE
 
  Since the Company routinely works with radioactive and hazardous materials,
the Company may be subject to liability claims by employees, customers and
third parties. There can be no assurance that the Company's existing liability
insurance is adequate to cover claims asserted against the Company, that all
claims asserted against the Company will be covered by insurance or that the
Company will be able to maintain such insurance in the future. An uninsured
claim, if successful and of sufficient magnitude, could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business--Risk Management and Insurance."
 
DEPENDENCE ON AND LIMITED PROTECTION OF TECHNOLOGY AND INTELLECTUAL PROPERTY;
POTENTIAL LITIGATION
 
  The Company's ability to compete effectively is dependent upon its
vitrification and other waste treatment technologies. The Company principally
relies upon 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 establish and protect
the proprietary aspects of its waste treatment technologies. In addition, the
Company has filed one patent application currently pending in the U.S. Patent
and Trademark Office. There can be no assurance that the patent will issue,
and there can be no assurance regarding the scope, validity or value of any
patents or other methods of intellectual property rights protection relied
upon by the Company. Further, there can be no assurance that the steps taken
to protect proprietary technologies by the Company and the owners of any
licensed patents and other intellectual property rights will be adequate to
prevent the use of these technologies by third parties. There can be no
assurance that others will not develop proprietary technologies and processes
which are the same as or superior to those of the Company. In the event that
the Company pursues overseas projects, there can be no assurance that steps
taken by the Company and the owners of any licensed patents and other
intellectual property rights to protect their proprietary technologies will be
adequate under the laws of certain foreign countries. The loss of patent or
other forms of intellectual property rights protection on the Company's
technology or the circumvention of such protection by competitors could have a
material adverse effect on the Company's ability to compete successfully with
its waste treatment technologies. See "Business--Intellectual Property."
 
  Many technology fields are characterized by the existence of a large number
of patents and frequent litigation regarding possible infringement. Although
the Company does not believe that any of its technologies infringes the patent
rights of third parties, there can be no assurance that infringement claims
will not be asserted against the Company in the future or that any such claims
will not require the Company to enter into royalty or other settlement
arrangements or result in costly litigation.
       
ABSENCE OF PRIOR PUBLIC MARKET AND POSSIBLE VOLATILITY OF STOCK PRICE;
DILUTION
 
  Prior to the Offering there has been no public market for the Common Stock.
Although the Company has applied to have the Common Stock included on the
Nasdaq National Market, there can be no assurance that an active trading
market for the Common Stock will develop or be sustained after the Offering.
The initial public offering price will be determined through negotiations
between the Company and the Representative, and may not be indicative of the
market price at which the Common Stock will trade after the Offering. (See
"Underwriting" for a discussion of the factors to be considered in determining
the initial public offering price.) Additionally, the market price of the
Common Stock may be subject to significant fluctuations in response to
variations in actual and anticipated quarterly operating results and other
factors, including announcements of new
 
                                      10
<PAGE>
 
contracts or technical innovations by the Company or its competitors, changes
in government regulations relating to the environment, the volume of market
transactions in the Common Stock and general market conditions.
   
  Purchasers of the Common Stock offered hereby will incur immediate and
substantial dilution in the net tangible book value of their shares. See
"Dilution." To the extent that the Representative's Warrants, any of the
outstanding options to purchase an aggregate of 1,000,000 shares of Common
Stock or any options granted in the future under the Company's 1998 Stock
Ownership Incentive Plan or 1998 Non-Employee Directors' Stock Option Plan are
exercised, the percentage ownership of the Company's shareholders will be
diluted proportionately. See "Underwriting," "Description of Capital Stock--
Options," "Management--Employee Benefit Plans--Stock Ownership Incentive Plan"
and "--Board of Directors--Non-Employee Directors' Stock Option Plan."     
 
SHARES ELIGIBLE FOR FUTURE SALE
   
  Future sales of substantial amounts of Common Stock in the public market
could have an adverse effect on the market price of the Common Stock. Upon
completion of the Offering, the Company will have outstanding approximately
13,215,896 shares of Common Stock (13,470,896 shares, if the Underwriters'
over-allotment option is exercised in full), of which 1,700,000 shares offered
hereby (1,955,000 shares if the Underwriters' over-allotment option is
exercised in full) will be freely tradeable without restriction or further
registration under the Securities Act to the extent they are not held by
"affiliates" of the Company, as that term is defined in Rule 144 ("Rule 144")
promulgated under the Securities Act of 1933, as amended (the "Securities
Act"). The remaining 11,515,896 shares of Common Stock outstanding upon
completion of the Offering will be "restricted securities" as that term is
defined in Rule 144. The Company's officers, directors and certain
shareholders have executed lock-up agreements generally providing that they
will not sell or otherwise dispose of Common Stock for a period of 180 days
after the date of this Prospectus without the prior written consent of Van
Kasper & Company (and in certain cases that they will only sell subject to
certain conditions on sale for an additional 180 days thereafter). Taking into
account the existence of such lock-up agreements and assuming the shareholders
are not released from these agreements, all 11,515,896 shares constituting
restricted securities will become eligible for sale under Rule 144 180 days
after the date of this Prospectus, with 8,248,201 of such shares being subject
to certain conditions on sale for an additional 180 days thereafter, of which
2,520,926 shares will be held by affiliates. Shares eligible to be sold by
affiliates are generally subject to volume limitations under Rule 144. The
existence of a large number of shares eligible for future sale could have an
adverse effect on the Company's ability to raise additional equity capital or
on the price at which such equity capital could be raised. See "Shares
Eligible for Future Sale."     
 
ABSENCE OF DIVIDENDS
 
  The Company has never declared or paid any dividends on the Common Stock.
The Company currently anticipates that it will retain all future earnings for
use in the operation and growth of its business and does not anticipate paying
any cash dividends in the foreseeable future. In addition, the terms of the
Company's outstanding bank borrowings currently prohibit the payment by the
Company of dividends without the lender's prior approval. See "Dividend
Policy."
 
 
                                      11
<PAGE>
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby, at an assumed initial public offering price of $9.00 per share
(the midpoint of the price range set forth on the outside front cover page of
this Prospectus), and after deducting estimated offering expenses and
underwriting discounts, are estimated to be approximately $13,229,000
($15,329,000 if the Underwriters' over-allotment option is exercised in full).
   
  The Company intends to use the net proceeds from the Offering approximately
as follows: (i) $4.0 million for capital equipment at its Richland, Washington
facilities; (ii) $4.0 million to repay all amounts of principal and interest
outstanding under its bank line of credit facility, which expires in June 1998
and bears interest at a rate per annum of prime plus 0.5%; and (iii) the
balance for working capital and general corporate purposes, which may include
the construction of additional fixed waste treatment facilities and possible
acquisitions or joint ventures in connection with the expansion of its
existing business lines. The Company is not currently a party to any
commitments or agreements relating to, and is not currently involved in any
negotiations with respect to, any such acquisitions or joint ventures.     
   
  The Company expects that the net proceeds of the Offering, together with
anticipated cash flow from operations and available borrowings under the
Company's credit facility, will satisfy its capital requirements for the next
12 months. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources." Pending
application of the net proceeds of the Offering to the uses described above,
the Company intends to invest the proceeds in short-term investment grade,
interest-bearing securities.     
 
                                DIVIDEND POLICY
 
  The Company currently intends to retain any future earnings for use in the
operation and growth of its business. The Company does not anticipate paying
any cash dividends on the Common Stock in the foreseeable future. Any future
decision to declare or pay cash dividends on the Common Stock will depend upon
the results of operations, financial condition and capital expenditure plans
of the Company at that time, as well as other factors that the Company's Board
of Directors (the "Board"), in its sole discretion, may consider relevant. In
addition, the terms of the Company's bank borrowings currently prohibit the
payment by the Company of cash dividends on the Common Stock without the
lender's prior approval.

                                   DILUTION
 
  As of December 31, 1997, the pro forma net tangible book value per share of
the Common Stock was $1.67. Pro forma net tangible book value per share of
Common Stock is equal to the total tangible assets of the Company less total
liabilities, divided by the number of shares of Common Stock deemed to be
outstanding. After giving effect to the issuance of shares in the Offering at
an assumed initial public offering price of $9.00 per share, and after
deducting estimated offering expenses and underwriting discounts, the adjusted
pro forma net tangible book value per share of Common Stock as of December 31,
1997 would have been $2.46. This represents an immediate dilution of $6.54 per
share to new investors purchasing Common Stock in the Offering. The following
table illustrates this per share dilution.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion and analysis should be read in conjunction with the
Company's Consolidated Financial Statements and the Notes thereto and the
other financial information included elsewhere in this Prospectus. Except for
the historical information contained herein, the discussions in this
Prospectus contain forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially from those
discussed herein. Factors that could cause or contribute to such differences
include, but are not limited to, those discussed below and in the section
entitled "Risk Factors" as well as those discussed elsewhere in this
Prospectus.
 
OVERVIEW
 
  The Company is a radioactive and hazardous waste management company that
offers comprehensive treatment solutions for LLRW, LLMW and other waste
generated by the DOD, DOE and commercial entities such as nuclear power
plants, medical facilities and research institutions. Founded in 1976 to
provide technical consulting and support services to participants in the
nuclear power industry, the Company expanded into D&D services in 1980 when it
received its first multi-year contract for a DOE facility. Following an
employee leveraged buy-out in 1984, new management commenced the
diversification of the Company's business into waste processing and treatment.
The Company 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.
 
  The U.S. government represented 86.3%, 76.8% and 71.3% of the Company's
total annual revenue for the years 1995, 1996 and 1997, respectively. Revenue
from commercial entities, primarily nuclear power plants, industrial concerns
and medical and research institutions, has increased in recent years and is
expected to represent an increasing portion of the Company's business. Revenue
from waste treatment processing is recognized as waste is processed. 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 the Company's business, which
varies from time to time. Gross profit margins are generally higher for
technology transfer agreements involving up-front, non-refundable, exclusive
licensing fees payable to the Company, and, due to the extensive expertise the
Company has developed in this area, when the Company is processing radioactive
waste, while margins on nonradioactive waste projects generally are lower. The
Company intends to focus a significant portion of its business on SAFGLAS
vitrification of LLRW in 1998 and on LLMW processing in 1999.
 
  The Company operates its fixed facilities under regulation of, and licenses
and permits issued by, various federal, state and local agencies. There is no
assurance 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. The Company's 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 the
Company's financial position and results of operations.
 
  The Company 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 its fixed operating facilities, particularly in connection
with the SAFGLAS system. The Company anticipates that its research and
development efforts will continue to be moderate and that the costs associated
with future research and development will not be material to the Company's
results of operations.
 
  The Company 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
 
                                      16
<PAGE>
 
marketing costs. The Company currently focuses on large, multi-year site-
specific and term contracts in the areas of LLRW and LLMW treatment,
environmental restoration and D&D, and has in recent years 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 the Company 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 the Company's 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 the Company than
anticipated.

4.8%, compared to $18.2 million in 1996. The growth in revenue resulted from a
change in mix of the business services and the receipt of fees for technology
transfer agreements. Revenue from waste treatment services was $9.6 million in
1997 compared to $8.9 million in 1996. Revenue from field engineering services
was $9.5 million in 1997 compared to $9.3 million in 1996. During 1997 the
Company entered into two technology transfer agreements (with total 1997
revenue of approximately $2.0 million derived from up-front, non-refundable,
exclusive licensing fees) that provided for the transfer of rights to the
processes and technology of the Company on an exclusive basis in selected
Asian territories. Revenue from various agencies of the U.S. government
accounted for 71.3% and 76.8% of total revenue in 1997 and 1996, respectively.
One contract with an agency of the U.S. government accounted for approximately
21.0% of the Company's total revenue for 1997. Two contracts with agencies of
the U.S. government accounted for 12.5% and 12.0%, respectively, of the
Company's total revenue for 1996.     
 
  Gross Profit. Gross profit for 1997 was $7.9 million, an increase of $0.7
million, or 10.9%, compared to $7.2 million for 1996. Gross profit as a
percentage of revenue increased to 41.5% in 1997 compared to 39.2% in 1996.
Gross profit percentages reflect the various mixes of the Company's business
services from time to time. Gross profit in 1997 includes the effect of the
technology transfer licensing fee revenue. Gross profit margins are generally
higher for technology transfer agreements and, due to the extensive expertise
the Company has developed in this area, when the Company is processing
radioactive waste, while margins on nonradioactive waste projects generally
are lower. Although the gross profit margins increased from 1997 to 1996,
there can be no assurance that similar margins will be attained in future
periods. Any shift in the mix of business in future periods to lower margin
projects could adversely affect the Company's results of operations.

  Sales, General and Administrative Expenses. Sales, general and
administrative expenses (including stock-based compensation expense) were $7.0
million for 1997, an increase of $0.3 million, or 5.5%, compared to $6.7
million in 1996. Sales, general and administrative expenses were 36.7% of
revenue in 1997 compared to 36.5% of revenue in 1996. 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 of the
Company. The overall increase as a percentage of revenue is attributable to
the Company's hiring in 1997 of senior management personnel to support the
Company's future growth.     
 
  Interest Income and Interest Expense. Interest income was $58,000 in 1997
compared to $142,000 in 1996. The decrease in interest income is attributable
to a lower overall average of cash available for investment in 1997. In 1996
the Company sold $5.9 million of preferred stock and invested the net proceeds
in interest bearing accounts until they were needed for capital expenditures
and working capital. In 1997 the Company sold $1.7 million in additional
preferred stock. Interest expense was nil in 1997 as the result of the Company
capitalizing $891,000 of interest on construction in progress in accordance
with generally accepted accounting principles. (See Note 5 of Notes to
Consolidated Financial Statements.) Interest expense in 1996 was $129,000,
which was net of $446,000 of interest capitalized on construction in progress.
 
 COMPARISON OF YEARS ENDED DECEMBER 31, 1996 AND 1995
 
  Revenue. Revenue for 1996 was $18.2 million, an increase of $2.1 million, or
13.5%, compared to $16.1 million for 1995. The growth in revenue resulted from
increases in the size and number of both field engineering and waste treatment
projects, and an increase in the number of new customers. Revenue from waste
treatment services was $8.9 million in 1996 compared to $8.0 million in 1995.
Revenue from field engineering services was $9.3 million in 1996 compared to
$8.1 million in 1995. Revenue from various agencies of the U.S. government
accounted for 76.8% and 86.3% of total revenue in 1996 and 1995, respectively.
One contract with an agency of the U.S. government accounted for 12.5% and
21.9% of the Company's total revenue in 1996 and 1995, respectively. A
contract with one other agency of the U.S. government accounted for 12.0% of
the Company's total revenue for 1996.
 
  Gross Profit. Gross profit for 1996 was $7.2 million, an increase of $0.8
million, or 11.6%, compared to $6.4 million in 1995. Gross profit as a
percentage of revenue remained relatively constant at 39.2% in 1996 compared
to 39.9% in 1995. Gross profit percentages reflect the various mixes of the
Company's business services from time to time. The decrease in the gross
profit percentage from 1995 to 1996 reflects this change in mix.
 
  Sales, General and Administrative Expenses. Sales, general and
administrative expenses (including stock-based compensation expense) were $6.7
million for 1996, an increase of $0.5 million, or 7.3%, compared to $6.2
million for 1995. Sales, general and administrative expenses were 36.5% of
revenue in 1996 compared to 38.6% of revenue in 1995. The overall decrease as
a percentage of revenue is attributable to the Company's effort to maintain a
level of costs that does not increase at the same rate as revenue.
 
  Interest Income and Interest Expense. Interest income was $142,000 in 1996
compared to $185,000 in 1995. The decrease in interest income is attributable
to a lower overall average of cash available for investment in 1996 than in
1995 due to the timing of sales of preferred stock and the use of the cash for
capital expenditures and working capital. Interest expense for 1996 was
$129,000 compared to $326,000 for 1995. The higher interest expense in 1995
resulted from an increase in working capital borrowing to finance the increase
in accounts receivable in 1995 over 1994. Accounts receivable increased from
approximately $3.9 million at fiscal year-end 1994 to $7.4 million at fiscal
year-end 1995. Additionally, in 1995 and 1996 the Company capitalized a
portion of its interest expense in accordance with generally accepted
accounting principles. The interest expense capitalized was directly
attributable to construction in progress on the SAFGLAS system.

  Revenue and Gross Profit. In the fourth quarter of 1997, the Company
performed a contract for which a significant change order was pending as of
December 31, 1997. As a consequence, the Company did not recognize revenue from
the change order or record any gross profit with respect to the contract in the
fourth quarter of 1997, and will recognize such revenue when and to the extent
acceptance by the customer of the change order is deemed probable.     
   
  The Company's revenue is dependent on the amount of its contract backlog, the
timing and performance requirements of each contract and, in the case of
government contracts, annual budget limitations and public sector budget
constraints. Revenue in the first and second quarters has historically been
lower than in the third and fourth quarters, as the Company's customers have
tended to ship waste during the months in which transportation is less likely
to be adversely affected by weather conditions. The Company's revenue is also
affected by the timing of its clients' planned remediation activities and need
for waste treatment services, which generally increase during the third and
fourth quarters. The Company's gross profit margins are affected by numerous
factors, including the revenue factors referred to above, growth in the
Company's operations infrastructure, international expansion and the extent and
timing of change orders, which factors can vary significantly from quarter to
quarter. Due to these factors, the Company's quarterly results fluctuate.
Accordingly, specific quarterly or interim results should not be considered
indicative of results to be expected for any future quarter or for the full
year. See "Risk Factors--Seasonality and Fluctuation in Quarterly Results."
    
LIQUIDITY AND CAPITAL RESOURCES
 
  Prior to 1994, the Company financed its operations, acquired equipment and
met its working capital requirements through sales of common stock, borrowings
under its revolving line of credit and long-term loans and capital leases
secured by property and equipment. In 1994 the Company sold 900,000 shares of
Preferred Stock at $5.00 per share. The proceeds from this financing were used
to acquire property and equipment in the amount of $3.2 million, and the
balance for working capital needs.
 
  In 1995 the Company's subsidiary, ATG Richland, sold 860,000 shares of its
Series A Redeemable Non-Voting Preferred Stock at $5.00 per share and in 1996
sold 990,355 shares of its Series B Redeemable Non-Voting Preferred Stock at
$6.00 per share. Of the $10.2 million raised in these two financings, $7.3
million was used to acquire property and equipment, and $2.9 million for
working capital. In 1997 ATG Richland sold an
 
                                       19
<PAGE>
 
additional 278,936 shares of its Series B Redeemable Non-Voting Preferred
Stock at $6.00 per share. The $1.7 million raised in this transaction was
primarily used to fund the installation and start-up of the SAFGLAS system at
the Company's Richland facilities.
 
  During 1995 the Company used cash of $3.4 million in its operating
activities. Operating cash used in 1995 resulted primarily from an increase in
accounts receivable related to significant growth in sales. In 1996, cash of
$2.9 million was generated from operations, primarily from increased
profitability and reduction in accounts receivable as well as other working
capital changes. In 1997, cash of $1.0 million was generated from operations,
primarily from increased profitability.
   
  Significant outlays of cash have been needed to acquire property and
equipment, primarily for the Company's Richland facilities. Property and
equipment acquisitions totaled $2.7 million, $4.6 million and $7.8 million in
1995, 1996 and 1997, respectively. The Company anticipates that continued
expansion of its Richland LLRW treatment facilities will cost approximately
$4.0 million, which the Company plans to finance from the proceeds of the
Offering. The Company currently expects to spend in 1999 in excess of
$10 million for the construction of the mixed waste treatment facility to be
sited at its Richland facilities.     
   
  The working capital of the Company was approximately $1.7 million at
December 31, 1997. The Company's principal sources of liquidity at December
31, 1997 consisted of $2.6 million of cash and cash equivalents. It is
anticipated that bank borrowings will be repaid from the proceeds of the
Offering.     
   
  Under the terms of a revolving credit facility with a bank, the Company may
borrow up to the lesser of 90% of eligible accounts receivable or $5.0
million. Borrowings under this credit facility were $4.0 million at December
31, 1997, bear interest at an annual rate of prime plus 0.50% (9.0% at
December 31, 1997) and are collateralized by accounts receivable, property and
equipment and the personal guarantee of the Company's principal shareholder.
The credit agreement requires the Company to comply with certain covenants,
including covenants relating to quick ratio, capital expenditure limits,
limits on additional indebtedness, debt service coverage, minimum levels of
tangible net worth and dividend payment restrictions. At December 31, 1997 and
at various dates throughout the year, the Company was in violation of the
quick ratio, capital expenditure and additional indebtedness covenants. The
Company has obtained waivers in respect of each of these violations as of
December 31, 1997.     
 
  The Company believes that the net proceeds from the Offering, together with
the availability of its line of credit and cash generated from operations,
will be sufficient to meet the Company's capital requirements for the next 12
months. Depending on its rate of growth and profitability, the Company may
require additional equity or debt financing to meet its future working capital
or capital expenditure needs. There can be no assurance that such additional
financing will be available or, if available, that such financing can be
obtained on terms satisfactory to the Company.
 
ACCOUNTING PRONOUNCEMENTS
 
  In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income." SFAS No. 130 establishes standards for
reporting and displaying comprehensive income and its components in the
consolidated financial statements. It does not, however, require a specific
format for the statement, but requires the Company to display an amount
representing total comprehensive income for the period in that financial
statement. SFAS No. 130 is effective for the Company's 1998 fiscal year.
 
YEAR 2000 MODIFICATIONS
 
  The Company is not highly dependent on internal computer systems, and does
not, as a general matter, interact electronically with its customers or
suppliers. The Company is currently reviewing its computer systems in order to
evaluate what, if any, corrections or modifications may be necessary for the
year 2000.

GENERAL
 
  The Company, founded in 1976, is a radioactive and hazardous waste
management company that offers comprehensive treatment solutions for LLRW and
LLMW generated by the DOD, the DOE and commercial entities such as nuclear
power plants, medical facilities and research institutions. The Company's
thermal treatment technologies vitrify waste into leach-resistant glass for
long-term storage or disposal. Compared with the more traditional incineration
methods, the Company's vitrification process results in significantly less
effluents, provides a more stable end product and achieves comparable volume
and mass reduction at similar total treatment and disposal costs.
 
  The Company operates through its Fixed Facilities Group, which manages its
waste treatment operations, and its Field Engineering Group, which addresses
D&D of radioactive facilities and environmental restoration of sites
contaminated with radioactive and hazardous waste. The synergies between the
on-site remediation services of its Field Engineering Group and the waste
treatment operations of its Fixed Facilities Group enhance the Company's
ability to compete for commercial and government LLRW and LLMW treatment
contracts. The Company directs waste removed from the field to its fixed
facilities for treatment when more cost-effective for the customer. In
addition, the Company's radioactive material license issued by the State of
Washington with respect to its Richland facilities includes reciprocity
provisions that the Company believes allow it to thermally and non-thermally
treat radioactive waste at customer sites in all fifty states.
 
  The Company believes that it possesses a number of competitive advantages
which distinguish it from other radioactive and hazardous waste management
companies, including the broad and comprehensive spectrum of the services it
offers, the extensive portfolio of licenses and permits it holds or is in the
process of obtaining, the cost-efficiency and environmental integrity of its
waste treatment technologies, and its established positioning with both
commercial and government customers, as well as with U.S. federal, state and
local environmental regulators.
 
MARKET OVERVIEW
   
  General. The worldwide environmental services industry is diverse and
growing. This growth has been driven by extensive legislation and governmental
regulation aimed at protecting the environment and requiring responsible
parties to clean up existing environmental hazards. According to industry
sources, the overall market for environmental services, including solid waste
management and water treatment services, is approximately $190 billion a year
in the United States and $25 billion a year in Asia (excluding Japan), and is
projected to grow at an annual rate of 4%, in the U.S. and 17% in Asia
(excluding Japan) through the year 2001. Although the ultimate impact of the
recent economic instability in certain Pacific Rim countries on the local
economies cannot yet be determined, the underlying structural problems, if not
ameliorated in the near term, could lead to a significant reduction in the
projected demand for environmental services in that region.     
 
  The Company believes that the specific environmental services markets within
which it competes have evolved so that actual remediation and site clean-up,
including the treatment and disposal of LLRW, LLMW and hazardous waste, will
command a growing portion of environmental resources worldwide. The following
is a description of each of these types of waste and a summary of the
potential market for the services offered by the Company.
 
  LLRW Treatment Market. 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. LLRW is all radioactive material other than high-level
radioactive waste ("HLW"). HLW 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. Most LLRW consists of
relatively large amounts of
 
                                      21
<PAGE>
 
waste materials contaminated with small amounts of radioactivity, such as
contaminated equipment, protective clothing, paper, rags, packing material,
liquids and sludge. The Company has been engaged in the business of handling,
treating, storing and disposing of LLRW since 1988.
 
  The Company estimates that currently more than $150 million is spent
annually in the United States on the treatment of commercial LLRW. The Company
believes that the size of the commercial LLRW treatment market in the United
States will increase significantly as the result of the LLRW required to be
treated in connection with the expected decommissioning of up to ten nuclear
power plants in the United States over the next decade. Significant demand
exists in the United States for the volume and mass reduction of commercially
generated LLRW, as there are at present only two full-service disposal sites
in the nation accepting such waste. These sites, which are located in
Barnwell, South Carolina and Richland, Washington, base the disposal fees
charged to customers on the volume and mass of the waste to be disposed. The
Barnwell disposal site, which currently services the majority of commercial
LLRW 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 $400 per cubic foot, and from $4.00 to $7.00 per pound,
depending upon the waste's density and activity levels. The disposal fees
charged by the Richland site are significantly lower, but this site is only
permitted to accept waste generated in 11 states. In addition, there is 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 LLRW with only small concentrations of radioactivity. See "--
Competition." There are at present only two companies licensed to offer volume
and mass reduction by thermal treatment of a broad spectrum of commercial LLRW
in the United States: the Company, through its SAFGLAS vitrification
technology, and GTS Duratek, Inc. ("Duratek"), through its incineration
treatment processes.
   
  Significant amounts of LLRW are also generated by and stored on federal
government sites, principally the former nuclear weapon production facilities
administered by the DOE. The DOE estimates that there is in excess of 53
million cubic feet of LLRW either currently stored or expected to be generated
during the next 20 years at DOE facilities throughout the United States alone.
Of this estimated total, the DOE's Hanford and Savannah River Reservations
account for approximately 6% and 34%, respectively. The DOE also estimates
that the total treatment costs for the LLRW at these two sites alone will
exceed $850 million through the year 2010.     
 
  LLMW Treatment Market. Low-level mixed waste is low-level radioactive waste
co-mingled with hazardous substances regulated by the Resource Conservation
and Recovery Act of 1976 ("RCRA") and/or toxic substances regulated by the
Toxic Substances Control Act of 1976 ("TSCA"). LLMW results from a variety of
activities, including the processing of nuclear materials used in nuclear
weapon production, nuclear energy research and the generation of nuclear
energy. The clean-up of government-generated LLMW is driven by the Federal
Facilities Compliance Act of 1992 (the "FFCA"), which requires that
radioactivity-contaminated federal facilities meet waste clean-up targets by
specified dates. For example, DOE-Hanford is required to commence non-thermal
treatment of the LLMW stored there by September 30, 1999, and thermal
treatment of such waste by December 31, 2000.
 
  Significant quantities of untreated LLMW 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 DOE estimates that there
is in excess of 7.7 million cubic feet of LLMW either currently stored or
anticipated to be generated over the next two decades throughout the United
States at DOE facilities alone, with approximately 16% and 9% of this
estimated total allocated to the DOE's Hanford and Savannah River
Reservations, respectively. The DOE also estimates that the treatment cost for
the LLMW at these sites alone will exceed $580 million through the year 2010.
The Company is not aware of any reliable estimates of the existing backlog of
commercially generated LLMW awaiting treatment at generators' sites. However,
according to a survey study sponsored by the Nuclear Regulatory Commission
("NRC") and the Environmental Protection Agency ("EPA"), approximately 140,000
cubic feet of LLMW was commercially generated in the United States in 1990.
The Company believes that the size of the commercial LLMW treatment market in
the United States will increase significantly as the result of the LLMW
required to be treated in connection with the expected decommissioning of up
to ten nuclear power plants in the United States over the next decade.
 
                                      22
<PAGE>
 
  The Company believes that its mixed waste treatment facility will, upon
completion of its pending permitting process, be the first privately owned
facility in the United States licensed to thermally and non-thermally treat a
broad spectrum of commercial and government-generated LLMW.
 
  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. The Company to date has not attempted to penetrate the
large and highly competitive hazardous waste treatment market, except as a
component of the environmental restoration and D&D services provided by its
Field Engineering Group. Historically, the Company has processed a broad range
of hazardous substances at client sites in the execution of environmental
restoration and D&D projects.
 
GROWTH STRATEGY
 
  To expand its business, the Company plans to (i) establish significant
positions in certain emerging or underserved, higher-margin segments within
the markets for treatment of LLRW, LLMW, hazardous and other waste, (ii)
increase its participation on teams bidding for and executing large-scale,
multi-year D&D and environmental restoration contracts, and (iii) enhance its
ability to provide on-site full-service solutions for D&D and environmental
restoration projects. The Company's growth strategy is focused on achieving
the following five objectives:
     
    Increase Market Share in Domestic Commercial LLRW Treatment Market. The
  Company intends to increase its share of the domestic commercial LLRW
  treatment market by marketing its SAFGLAS vitrification system as a
  competitive alternative to incineration, the only other thermal treatment
  method widely available in the United States for commercial LLRW. As
  disposal costs have increased significantly in recent years, the volume and
  mass reduction achievable by thermal treatment has become a critical factor
  in selecting a waste treatment solution for many commercial LLRW
  generators. With the commencement of the commercial operation of its
  SAFGLAS system in the third quarter of 1997, the Company now offers a non-
  incineration thermal process that results in total treatment and disposal
  costs for the customer comparable to those achieved by incineration.
  Additionally, the end-stage glass product resulting from this process is
  more suitable for long-term storage and disposal than incineration fly ash.
  The Company believes that any competitor attempting to build and operate a
  commercial LLRW thermal treatment facility in the United States would
  require several years to secure the requisite regulatory approvals. As of
  December 31, 1997, the Company was a party to service agreements with three
  nuclear utilities, covering four nuclear power plants, to accept and treat
  LLRW generated by such utilities. In the first quarter of 1998, the Company
  entered into such service agreements with an additional seven nuclear
  utilities, covering an additional fifteen nuclear power plants.     
 
    Establish Significant Position in Domestic LLMW Treatment Market. The
  Company intends to establish a significant position in the United States
  market for treatment of LLMW. The market for domestic LLMW treatment is in
  an early stage because approved technologies capable of treating a broad
  spectrum of low-level mixed waste streams previously have not been
  available. The Company has developed its GASVIT vitrification system for
  LLMW treatment and anticipates completing the pending licensing process for
  both thermal and non-thermal LLMW treatment methods at its Richland
  facilities in the fourth quarter of 1998. Thereafter, the Company expects
  to take approximately six and 12 months, respectively, to place its non-
  thermal and thermal treatment processes in operation. As a consequence, the
  Company believes it is positioned to be the first company to own and
  operate a private facility in the United States capable of thermally and
  non-thermally treating a broad spectrum of low-level mixed waste streams
  produced by commercial and government waste generators. The Company
  believes that any competitor attempting to build and operate a commercial
  LLMW thermal treatment facility in the United States would require a
  significant start-up period in which to develop and commercialize its
  technology and secure the requisite regulatory approvals. Consequently, the
  Company may have several years in which to establish its position in this
  market before experiencing significant competition.

    Enhance its Ability to Compete for Large Project Contract Awards. The
  Company intends to increase its participation on project teams led by large
  firms when such relationships are a practical requirement to compete
  successfully for large project contract awards. Increasingly, large-scale,
  multi-year D&D and environmental restoration contracts, whether to be
  performed domestically or overseas, require a team of companies with
  complementary expertise and skills within the industry, usually led by a
  large, multinational engineering or construction company. The Company
  believes that its expertise in niche areas within the radioactive and
  hazardous waste management industry makes it an attractive candidate for
  inclusion in teams competing for such contracts. In the last three years,
  the Company has been a member of teams executing DOE and DOD projects led
  by, among others, Lockheed Martin, Morrison Knudsen and Jacobs Engineering.
 
    Expand into Pacific Rim Markets. The Company intends to offer its SAFGLAS
  and GASVIT vitrification technologies for local treatment of LLRW and LLMW
  in selected Pacific Rim markets. The high cost of LLRW and LLMW disposal
  costs 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. The Company also believes
  there is a significant market for vitrification in the treatment and
  recycling of fly ash resulting from incineration of municipal waste in
  certain Pacific Rim markets where scarce land resources make landfill
  disposal of the ash uneconomical. Vitrification of fly ash through the
  Company's GASVIT system will allow the ash to be recycled for use as
  construction material and for other reuse purposes. To further promote use
  of its technologies and to establish strategic alliance relationships
  designed to accelerate penetration of these markets, the Company has
  entered into exclusive technology transfer agreements covering its
  technologies for Hong Kong, Taiwan and The People's Republic of China.
 
    Enhance On-Site Full-Service Treatment Capabilities. In order to enhance
  its ability to provide in-house a full range of D&D and environmental
  restoration services, including the application of vitrification treatment
  technology on-site, the Company is in the process of developing smaller-
  scale, transportable field applications of its GASVIT technology. The
  Company believes there is a significant trend in favor of D&D and
  environmental restoration contractors able to provide in-house a full range
  of such services on-site, including site assessment, feasibility study
  preparation, remediation design, remediation and removal actions, and
  thermal and non-thermal waste treatment. The Company believes that the
  development of smaller-scale, transportable GASVIT units will further
  distinguish it from most other radioactive and hazardous waste management
  companies.
 
WASTE TREATMENT TECHNOLOGIES
 
  A summary description of the Company's principal waste treatment
technologies for LLRW and LLMW is provided in the following table:

</TABLE>
 
 
  The core technology employed in the SAFGLAS and GASVIT systems is
vitrification. Although not widely utilized in this country to date,
vitrification technologies have been successfully used in Europe for over
thirty
 
                                      24
<PAGE>
 
years, principally in the area of HLW treatment. The EPA has identified
vitrification as the Best Demonstrated Achievable Technology (BDAT) for the
treatment of HLW, and the Company believes 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, the Company believes vitrification is widely perceived
as an environmentally superior waste treatment method. There can be no
assurance that the steps taken to protect the Company's technologies will be
adequate to prevent the use of such technologies by third parties. See "Risk
Factors--Dependence on and Limited Protection of Technology and Intellectual
Property; Potential Litigation."
       
  SAFGLAS--Thermal Treatment of LLRW by Vitrification. The SAFGLAS system
treats a broad spectrum of LLRW in the form of dry active wastes (protective
clothing, paper, rags, plastics, wood), low activity resins, aqueous based
liquids and sludges, and oils, which eliminates the customer's need to pre-
sort wastes to fit the specialized capabilities of a particular waste
processor's technology. The primary unit is a Joule-heated glass melter with a
multi-zone process chamber based on a technology that has been successfully
used for over 15 years in research on hazardous waste treatment. LLRW is fed
into a closed pool of molten glass at temperatures in excess of
2000(degrees)F. Most of the organic constituents are destroyed and the
radioactive solids are captured within the glass, which is periodically
drained into drums for disposal. The Company adapted the basic process to the
treatment of LLRW, including devising the systems for feed preparation, waste
feeding, and effluent treatment and monitoring. The SAFGLAS 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%. The Company believes that the highly
stable and leach-resistant nature of the glass produced by the SAFGLAS
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 LLRW.
   
  The basic SAFGLAS system is currently being enhanced through the addition of
a high temperature drum oven that will process biological LLRW as well as
materials with a high water content, and a small (100 lbs./hr.) version of the
Company's GASVIT system that will process wastes that either require small
batch processing or have very corrosive effluent gas that requires "scrubbing"
to remove corrosive constituents. Both the drum oven and the small GASVIT unit
exhaust into the second chamber of the basic SAFGLAS unit. The Company
therefore refers to the combination of these integrated technologies as the
SAFGLAS system, which is expected to be fully operational in the second
quarter of 1998. The combination of these processes is permitted to treat
approximately 12,000 pounds per day at full capacity. The basic SAFGLAS unit
has a permitted capacity of approximately 5,000-6,000 pounds per day,
depending on the type of feedstock. The Company's license allows it to operate
the SAFGLAS system 24 hours a day.     
       
  GASVIT--Thermal Destruction of LLMW by Gasification/Vitrification. The
Company has acquired licensing rights to use a proprietary plasma arc
technology developed by Integrated Environmental Technologies, LLC ("IET"),
for the treatment of LLMW. The IET plasma arc technology is being integrated
with the Company's technologies to form the GASVIT system. The GASVIT system
will be used as part of the SAFGLAS system for processing LLRW and will also
be used as the primary component in the Company's LLMW thermal processing
facility. Materials are fed into a process chamber where a combination of a
carbon induced plasma and joule heating at temperatures in excess of
2200(degrees)F transforms complex organic materials into a "syngas," which is
a mixture of hydrogen and carbon monoxide. The syngas can be either used as
fuel or destroyed in a subsequent flameless oxidation process. As with the
SAFGLAS system process, the end result of the GASVIT system process is a
glass-like 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. IET's process chamber is based on several
prototype units constructed and tested for the DOE, including a 100 lbs./hr.
process chamber which has been tested at the DOE's Hanford Reservation since
1996. 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. The Company intends to add another unit as its capacity
needs increase.
 
                                      25
<PAGE>
 
  PLASTIMELT--Non-Thermal Encapsulation of LLMW. The Company has developed the
PLASTIMELT process for the encapsulation of LLMW in a plastic matrix when the
volume or mass reduction achievable by thermal treatment methods is
uneconomical or impractical. In this process, molten plastic is extruded into
or around the LLMW to create a waste form that meets applicable requirements
for land disposal. The Company has integrated this technology with its
supercompaction processes in a system which achieves a volume reduction factor
of greater than 9 to 1.
 
OPERATIONS AND SERVICES
 
  The Company provides radioactive and hazardous waste management services
through two operating units, the Fixed Facilities Group and the Field
Engineering Group.
   
  FIXED FACILITIES GROUP. The core of the Company's fixed facilities
operations, situated on a 45-acre site in Richland, Washington adjacent to the
DOE's Hanford Reservation, is one of the largest commercial radioactive waste
treatment and storage centers in the United States. This facility is currently
licensed to handle, treat and store a wide variety of LLRW and the Company is
in the process of securing the licenses, permits and approvals required in
order for this facility to thermally and non-thermally treat a broad spectrum
of low-level mixed waste streams produced by both commercial and government
generators. The Company also owns a four acre facility in Fremont, California
which houses the Company's corporate offices, as well as an LLRW storage and
transfer station that supports its Richland operations. The Company utilizes a
fleet of Company-owned trucks to transport waste intra-state to or from its
Richland and Fremont facilities, and utilizes third party commercial carriers
to transport waste inter-state to or from these facilities.     
   
  In 1997, the Company purchased 30 acres of undeveloped industrial land in
Aiken, South Carolina, located adjacent to the DOE's Savannah River
Reservation. The Company is currently considering construction of a fixed
facility principally devoted to LLRW treatment on this site. If constructed,
this facility will provide the Company with two LLRW processing sites, each
situated adjacent to one of the two full-service commercial LLRW disposal
sites currently open in the United States.     
   
  LLRW Treatment Services. Since 1988, the Company has treated and recycled
several million pounds of LLRW at its Richland facilities. Since being placed
in operation in September 1997, the SAFGLAS system has processed in excess of
150,000 pounds of LLRW. In addition to the DOE, DOD and other agencies of the
U.S. government, customers for the Company's LLRW treatment services include
over 20% of the nation's nuclear power plants, many major corporations, and
numerous universities, laboratories, hospitals and other research and medical
institutions. In 1995, the DOE awarded the Company, in a competitive bidding
process, a fixed unit price contract to process LLRW generated by the Hanford
Reservation. The maximum value of the contract to the Company is $17 million
over five years.     
 
  LLMW Treatment Services. In December 1994, the Company began the licensing,
design and facility construction process for a mixed waste treatment and
storage facility to be sited at its Richland facilities. The Company intends
to use the mixed waste facility to treat LLMW, initially from the Hanford
Reservation, and subsequently from other DOE and other U.S. government and
commercial generators of LLMW. The Company intends to thermally treat LLMW by
means of its GASVIT system; when it is uneconomical or impractical to treat
LLMW by a thermal method, the Company intends to employ a number of
stabilization and encapsulation processes, including the Company's PLASTIMELT
process.
 
  In November 1995, the DOE awarded the Company, in a competitive bidding
process, the first privatized contract to thermally treat LLMW generated by
the Hanford Reservation. This contract has a maximum value to the Company of
$24 million for treating 175,000 cubic feet of waste over ten years. The
Company has until the year 1999 to permit and construct an LLMW treatment
facility and to commence LLMW treatment. In addition, the DOE awarded the
Company in September 1997, in a competitive bidding process, the first
privatized contract to non-thermally treat LLMW generated by the Hanford
Reservation. This contract has a maximum value to the Company of $5 million
over a three year period commencing when the Company begins LLMW treatment
thereunder.
 
                                      26
<PAGE>
 
       
  FIELD ENGINEERING GROUP. The principal services provided by the Company's
Field Engineering Group are (i) D&D of nuclear power plants and other
facilities contaminated with LLRW, LLMW and hazardous waste, and (ii)
environmental restoration of sites contaminated with LLRW, LLMW and hazardous
waste. The Company's 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, waste brokerage and
transportation, waste treatment using the Company's technologies on-site or at
the Company's fixed facilities, and storage of waste at the Company's fixed
facilities.
 
  Decontamination and Decommissioning Services. Historically, D&D services
have been the Company's core specialty area. The Company has been involved in
D&D projects for over a decade and currently is involved in several D&D
projects for the DOE. Customers for the Company'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 DOE and DOD, which oversee the nation's nuclear weapon
production facilities.
   
  The Company believes 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 of the cost to decontaminate and
decommission nuclear power plants, as reported by the Nuclear Energy
Institute, a nuclear energy industry policy organization, the Company
estimates 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 DOD and DOE facilities which
are scheduled to be decommissioned over the next decade.     
 
  Environmental Restoration Services. The Company has historically
concentrated on environmental removal and remediation actions at contaminated
DOD sites. There are over 420 DOD sites contaminated with LLRW or LLMW.
According to the Defense Environmental Restoration Program Annual Report to
Congress for Fiscal Year 1996, allocations for funding environmental
restoration work on DOD sites are projected to be $2 billion a year through
the year 2000.
 
  Since 1989 the Company has executed more than 150 field engineering projects
relating to the environmental restoration of sites contaminated with LLRW,
LLMW, or hazardous waste throughout the United States and U.S. territories. In
addition, the Company is currently performing under three Total Environmental
Restoration Contracts (TERCs) with the U.S. Army Corps of Engineers, two Pre-
placed Remedial Action Contracts (PRACs) with the U.S. Army Corps of
Engineers, two Remedial Action Contracts (RACs) with the U.S. Navy and four
environmental restoration contracts with the DOE, collectively covering a 40
state area.
 
  For its military and industrial clients, the Company 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 LLRW and LLMW, the Company 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 LLRW
and LLMW. The Company believes that the reciprocity provisions of its
radioactive material license issued by the State of Washington with respect to
the Company's Richland facilities allow the Company to thermally and non-
thermally treat radioactive waste at customer sites in all fifty states.
 
BACKLOG
 
  The Company's backlog consists of confirmed purchase order contracts that
have been received and which are scheduled for completion within 12 months. A
large percentage of these contracts are with agencies and facilities within
the U.S. government, principally the DOD and DOE, and many have been awarded
under indefinite delivery or quantity terms. These 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 to
 
                                      27
<PAGE>
 
   
actual delivery orders being released. Accordingly, the Company's backlog as
of a particular date may not be indicative of sales for any period and the
Company therefore believes that backlog is not a reliable indicator of future
revenue. The Company's backlog for contracts planned to be completed in fiscal
1998 that are not subject to indefinite delivery or quantity terms is
approximately $16 million. See "Risk Factors--Dependence on Federal
Government; Limits on Government Spending; Government Contracting" and "--
Seasonality and Fluctuation in Quarterly Results."     
 
CUSTOMERS
 
  The Company's services are provided to a broad range of federal, state and
local government and commercial clients in the United States. Demand for the
Company's services and the distribution of such demand are heavily 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 its technical expertise, extensive portfolio of
environmental licenses and permits and full-service capabilities on-site, the
Company has successfully bid on and executed a substantial number of waste
treatment, environmental restoration, D&D and other contracts with the DOD,
DOE and a number of other federal government agencies, as both a prime
contractor and as a subcontractor. In fiscal 1995, 1996 and 1997, the
percentage of the Company's total revenue attributable to such contracts was
86.3%, 76.8% and 71.3%, respectively. One contract with the U.S. Army Corps of
Engineers-Sacramento District accounted for 21.0% of the Company's total
revenue in the year ended December 31, 1997. One contract with the U.S. Army--
Fort Irwin accounted for 21.9% and 12.5% of the Company's total revenue in the
years ended December 31, 1995 and 1996, respectively. A contract with the U.S.
Army--Presidio accounted for 12.0% of the Company's total revenue in the year
ended December 31, 1996. The Company also serves numerous commercial clients,
including large industrial concerns, nuclear power plants, hospitals,
laboratories and other medical institutions, and universities. A substantial
portion of the Company's commercial work represents new contracts awarded by
existing clients. No single commercial client accounted for 10% or more of the
Company's revenue in fiscal years 1995, 1996 or 1997. See "Risk Factors--
Dependence on Federal Government; Limits on Government Spending; Government
Contracting."
 
SALES AND MARKETING
 
  The Company relies on a direct sales and marketing staff of six 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, the Company relied on discrete
waste treatment projects and limited term remediation projects that typically
involved planned clean-ups of sites that were contaminated in the normal
course of manufacturing activity or quick response clean-ups of spills. The
Company now targets its marketing efforts on large, multi-year private sector
and government site-specific and term contracts in the areas of LLRW and LLMW
treatment, environmental restoration and D&D.
 
  The Company's key marketing strategy in the waste treatment area is to focus
its resources on emerging or underserved markets in which it has technological
or licensing advantages over existing and potential competitors. The Company
intends to further develop its network of strong client relationships with the
DOD, the DOE, other federal government agencies, leading domestic and foreign
industrial concerns and its other most significant clients, and with major
national and multinational engineering, construction and architectural
engineering firms and other of its co-participants in teams executing large,
multi-year environmental restoration and D&D projects. The Company believes
that these strategies have been validated by the significant number of
additional contracts awarded to it by existing customers for which it
previously provided significant services, and the number of teams on which it
has participated in recent years in the execution of large, multi-year
environmental restoration and D&D projects. See "Risk Factors--Focus on Larger
Projects."
 
  To further promote use of its technologies and to establish strategic
alliances designed to accelerate its penetration of selected Pacific Rim
markets, the Company has entered into exclusive technology transfer
 
                                      28
<PAGE>
 
agreements covering its technologies for Hong Kong, Taiwan, and The People's
Republic of China. These agreements require the Company to provide assistance
and know-how to its alliance partners, which have the right to exclusively
market the Company's technologies in these territories. The Company will share
in any profits generated from these efforts and is also entitled to a royalty
on revenue generated by the use of its vitrification technologies in these
territories. The Company is entitled to independently pursue opportunities
within these territories if its alliance partners decline to do so, and, if
certain minimum revenue is not achieved in these territories within an agreed
upon period, the Company may terminate the agreements.
 
COMPETITION
 
  In general, the radioactive and hazardous waste management industry is
highly competitive. The Company faces varying levels of competition in its
principal current and planned business lines. The Company believes that it
currently has only one principal competitor, Duratek, for the thermal
treatment of domestic LLRW, and a handful of small to mid-size competitors in
the non-thermal treatment of domestic LLRW. With respect to the domestic LLMW
treatment market, the Company believes that there are only four other
companies currently processing LLMW 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. Upon completion of the pending
licensing process for its mixed waste treatment facility, the Company believes
that it will operate the first private facility in the nation licensed to
thermally and non-thermally treat a broad spectrum of low-level mixed waste
streams produced by both commercial and government generators.
 
  The Company is aware that the commercial LLRW disposal site in Clive, Utah
is seeking to expand its acceptance criteria so that it can receive waste with
radioactivity levels higher than it is currently permitted to accept, and that
one or more additional domestic commercial LLRW disposal sites have commenced
the licensing process. Any increase in the number of licensed commercial LLRW
disposal sites in the United States or any decrease in the disposal fees for
LLRW charged by such sites could increase the competition faced by the Company
or reduce the competitive advantage of certain of the Company's treatment
technologies.
 
  The market for D&D and environmental restoration services is highly
competitive, with numerous companies of varying size, geographical presence
and capabilities participating. The Company believes that fewer than six of
these companies have 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 LLRW and LLMW.
 
  The Company believes that the principal competitive factors applicable to
all areas of its 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. The Company believes that it is, and will continue to be, able
to compete favorably on the basis of these factors. The Company also believes
that it has several competitive advantages, including its vitrification
technologies, 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,
geographical positioning, and integrated technological approach to waste
treatment solutions. Many of the Company's competitors have substantially
greater managerial, technical and marketing resources than the Company, and
there can be no assurance that one or more of the Company's competitors do not
possess or will not develop waste treatment technologies or field service
capabilities that are superior to or more cost effective than those of the
Company. In certain aspects of the Company's business, substantial capital
resources are required for facilities and equipment, and many of the Company's
competitors have substantially greater financial resources than the Company.
See "Risk Factors--Competition."
 
ENVIRONMENTAL CONTRACTOR RISKS
 
  Although the Company believes that it generally benefits from increased
environmental regulations affecting business, and from enforcement of those
regulations, increased regulation and enforcement also create significant
 
                                      29
<PAGE>
 
risks for the Company. The assessment, remediation, analysis, handling,
treatment and management of radioactive or hazardous substances necessarily
involve significant risks, including the risk of potentially large liabilities
arising from violations of environmental laws and regulations and of
liabilities to customers and third parties for damages arising from performing
services, either of which could have a material adverse effect on the
Company's business, financial condition and results of operations. In
addition, the Company, as a provider of services to federal and other
government agencies, is also subject to the specific risks associated with
government contracting.
   
  In May 1997, the U.S. Army terminated for default its contract with the
Company under which the Company acted as a prime contractor to "surface clear"
ordnance from a U.S. Army firing range at Fort Irwin, California. This
contract was otherwise scheduled to expire in June 1997. The termination
related to services provided by a Company subcontractor, and was based on the
U.S. Army's contention that scrap ordnance had been improperly certified by
the subcontractor as free of hazardous and explosive material. Subsequently,
the U.S. Army also demanded repayment from the Company of alleged
reprocurement costs totaling $945,000. The Company believes that it fully
complied with the terms of the contract and applicable laws and regulations,
and has challenged the default termination in the Court of Federal Claims.
Additionally, the Company believes it has no obligation to make repayments to
the U.S. Army because the costs sought are not proper reprocurement costs. The
Company has tendered the Army's claim to its insurance carrier and believes
that all costs and liability (if any) associated with the claim will be
covered by the Company's comprehensive general liability policy. The matter is
presently being handled on behalf of the Company by its insurer. See "Risk
Factors--Environmental Contractor and Regulatory Matters" and "--Dependence on
Federal Government; Limits on Government Spending; Government Contracting."
    
RISK MANAGEMENT AND INSURANCE
 
  The Company has adopted a range of risk management programs designed to
reduce potential liabilities, including policies to seek indemnity in its
contracts, other contract administration procedures, and employee health,
safety, training, and environmental monitoring programs. In addition, as a
result of the substantial number of government contracts it has been awarded
over the past several years, the Company has implemented a government
contracts compliance program. Although the Company believes its risk
management programs are appropriate, the Company cannot assure their adequacy
and their failure to adequately protect the Company could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
  The Company carries nuclear liability, comprehensive general liability,
comprehensive property damage, workers' compensation and other insurance
coverage that management considers adequate for the protection of the
Company's assets and operations. However, there can be no assurance that the
coverage limits of such policies will be adequate or that insurance will
continue to be available to the Company on commercially reasonable terms in
the future. A successful claim against the Company in excess of its insurance
coverage, or outside the scope of such coverage, could have a material adverse
effect on the Company's business, financial condition and results of
operations. Claims against the Company, regardless of their merit or outcome,
and whether or not insured, may also have an adverse effect on the Company's
reputation, which could have a material adverse effect on the Company's
business, financial condition and results of operations. See "Risk Factors--
Potential Environmental Liability and Insurance."
 
INTELLECTUAL PROPERTY
 
  The Company regards aspects of its waste treatment technologies and know-how
as proprietary and relies primarily on 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. The Company presently has a
patent application pending for the SAFGLAS system as incorporating a multi-
zone process chamber; however, there can be no assurance that such application
will be granted. The Company believes that the ownership of patents is not
presently a significant factor in its
 
                                      30
<PAGE>
 
business and that its success does not depend on the ownership of patents.
However, there can be no assurance that the Company will be successful in
protecting the proprietary aspects of its technology, nor that its proprietary
rights will preclude competitors from developing waste treatment technologies
equivalent or superior to that of the Company. In addition, effective
protection for the proprietary aspects of the Company's technologies may be
unavailable or limited in certain foreign countries. While the Company is not
aware that any of its waste treatment technologies infringe the rights of any
third parties, there can be no assurance that third parties will not claim
infringement by the Company with respect to its existing or future waste
treatment technologies. See "Risk Factors--Dependence on and Limited
Protection of Technology and Intellectual Property; Potential Litigation."
   
  The Company from time to time licenses the rights to use the intellectual
property of third parties embodied in certain subsystems of the Company's
technologies. In particular, the Company licenses certain such rights from the
owner of the patented technology embodied in the basic SAFGLAS system melter
and from IET 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 the Company to pay to the owner of the patent a
license fee in the amount of $35,000 for each SAFGLAS process chamber built by
the Company during a five-year period. With respect to any melter purchased by
the Company from IET, other than the two units it has initially contracted to
purchase, the Company's license with IET requires the payment of a royalty fee
to IET in the amount of 3% of the gross revenue generated by the Company from
processing radioactive waste using a treatment system incorporating such a
melter. The Company from time to time receives letters of inquiry from the
owners of patents requesting that the Company demonstrate that the technology
licensed to the Company by third parties does not infringe such patents. The
Company routinely refers these letters of inquiry to such licensors, who are
required pursuant to the terms of their license agreements with the Company to
defend the Company against infringement claims asserted by third parties
relating to the licensed technology and to indemnify the Company against any
resulting losses. With respect to each such letter of inquiry previously
received by the Company, the Company has been advised by the licensor that, in
the judgement of the licensor, the licensed technology as used by the Company
did not infringe the subject patents.     
       
  The Company requires each of its technical and engineering employees to
enter into standard agreements pursuant to which the employee agrees to keep
confidential all proprietary information of the Company and to assign to the
Company 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 the Company's technology without authorization or to develop similar
technology independently.
 
ENVIRONMENTAL LAWS AND REGULATIONS; LICENSING PROCESSES APPLICABLE TO LLRW AND
LLMW TREATMENT FACILITIES
 
  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. The
operations of the Company and of the Company's 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 the services offered by the Company.
   
  The Company believes that its compliance with environmental laws and
regulations will not have a material effect on its capital expenditures,
earnings or competitive position, except with respect to capital expenditures
for environmental control facilities. While it does not anticipate that the
amount of such expenditures will be material in 1998, the Company expects that
the amount of such expenditures required to be made in 1999, particularly in
connection with the construction of the mixed waste facility to be sited at
the Company's Richland facilities, will be material.     
 
                                      31

  Under the Atomic Energy Act of 1954 (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
LLRW and that require the licensing of commercial LLRW disposal sites.
 
  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 (BDAT) 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 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 ("SARA"), imposes strict, joint and several liability upon
(among other parties) 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 the Company if releases of hazardous substances
occur at treatment, storage, or disposal sites used by the Company. This
liability potentially extends to off-site storage and disposal facilities used
by the Company, any LLMW treatment and storage facilities owned by the
Company, and releases at a customer's facility caused by the Company. Because
customers of the Company also face the same type of liabilities, CERCLA and
SARA create incentives for potential customers of the Company to avoid off-
site treatment and disposal of hazardous substances in favor of on-site
treatment and recycling.
 
  The Emergency Planning Community Right-to-Know Act, which is part of SARA,
requires full disclosure of certain environmental releases to the public and
contributes to public awareness and activism regarding corporate environmental
management issues. To the extent a generator's waste can be reported as being
recycled, public pressure can be eliminated or significantly reduced and the
generator's image enhanced.
 
  The radioactive and hazardous components of LLMW are governed by separate
sets of laws and regulations discussed above. The radioactive component is
governed by the AEA and is regulated by the DOE for waste at DOE facilities
and by the NRC 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. The Company designs its LLMW and hazardous
waste treatment and processing systems with the goal of minimizing the
potential for release of hazardous substances into the environment. In
addition, the Company has 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.
 
  In transporting radioactive materials, the Company is subject to the
requirements developed by the U.S. Department of Transportation under the
Hazardous Materials Transportation Act, as amended by the Hazardous Materials
Transportation Uniform Safety Act. Shippers and carriers of radioactive
materials must comply with both the general requirements for hazardous
materials transportation and with specific requirements for the transportation
of radioactive materials.
 
  The Clean Air Act of 1970, as amended (the "Clean Air Act"), imposes strict
requirements upon owners and operators of facilities and equipment which emit
pollutants into the environment, including incinerators. Although the Company
believes that its waste treatment systems effectively trap particulates and
prevent hazardous emissions from being released into the environment, the
Clean Air Act may require additional controls.
 
                                      32
<PAGE>
 
  The Clean Water Act of 1972 (the "Clean Water Act") establishes standards,
permits and procedures for controlling the discharge of pollutants from
industrial and municipal wastewater sources. The Company believes that its
waste treatment technologies generally will not be subject to the water
pollution control requirements of the Clean Water Act because they are
designed to have no residual wastewater discharge.
 
  TSCA provides the EPA with the authority to regulate certain commercially
produced chemical substances. TSCA also established a comprehensive regulatory
program for polychlorinated biphenyls ("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 the Company's business. For example,
the federal Occupational Safety and Health Act imposes requirements designed
to protect the health and safety of workers, and the NRC has set regulatory
standards for worker exposure to radioactive materials. In addition, the
requirements of various other statutes, including the FFCA and the Uranium
Mill Tailings Radiation Control Act, may create opportunities for additional
use of the Company's services.
 
  Licensing Processes Applicable to LLRW and LLMW Treatment Facilities. 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 material 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.
 
  The Company initiated the mixed waste licensing process for its Richland
facilities in 1995 and expects to be able to commence non-thermal mixed waste
treatment there in the second quarter of 1999. In March of 1995, the Company
submitted a siting application to the Washington State Department of Ecology
("WDOE"). After conducting two different public hearings, WDOE approved the
Company's siting application in December of 1995. Immediately after procuring
this approval, the Company 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. The Company is at
present involved in negotiations with the agencies to resolve their comments
thereon. The next step in the permitting process is the development of the
permit language by the agencies and the holding of public hearings to solicit
public comments, as required by RCRA and TSCA regulations. The Company
presently
 
                                      33
<PAGE>
 
anticipates receiving final approval from WDOE and the EPA of its applications
relating to non-thermal and thermal treatment prior to the end of the fourth
quarter of fiscal 1998.
 
  In the event that the Company were to engage in the business of treating
LLRW and LLMW received from foreign generators at its fixed facilities, it
would be required to obtain a radioactive waste import permit from the NRC.
 
  The Company's fixed facilities may have to obtain permits under the Clean
Water Act, the Clean Air Act, RCRA and state equivalents. The requirement to
obtain such permits depends upon a facility's location and the expected
emissions from the facility. Additional state and local licenses or approvals
may also be required.
 
EMPLOYEES
 
  At December 31, 1997, the Company employed 168 full-time employees. To date,
the Company has been successful in attracting and retaining qualified
managerial and technical personnel, although there can be no assurance that
this success will continue. See "Risk Factors--Dependence on Key Personnel."
 
  At December 31, 1997, 34 of the Company's employees were represented by
labor unions under collective bargaining agreements. The Company cannot
predict whether any of its employees who currently are not represented by
unions will elect to be so represented in the future. The Company considers
its relations with its employees to be good and has never experienced a work
stoppage or strike.
 
PROPERTIES AND FACILITIES
   
  The Company's principal properties, all of which are owned by the Company,
are located in Richland, Wash., Fremont, Calif. and Aiken, S.C., and occupy
45, four and 30 acres, respectively. The facilities sited on the Richland
property presently consist of 13 buildings, covering an area of approximately
100,000 square feet, devoted to the Company's existing LLRW and future LLMW
treatment operations. The Company presently plans to construct two additional
buildings on this site of approximately 14,000 square feet in aggregate. The
facilities sited on the Fremont property include a 10,000 square foot
corporate office building, as well as an LLRW storage area. The Company's
Aiken property has not been developed to date.     
 
  In addition, the Company leases an approximately 1,200 square foot project
management office in Honolulu, Hawaii, and an approximately 2,500 square foot
project management office in Oak Ridge, Tennessee (approximately one mile from
the DOE's Oak Ridge Reservation). The Honolulu lease expires in June 2000,
while the Oak Ridge lease is month-to-month.
 
  The Company's Fremont property is encumbered by a deed of trust (the "First
Deed of Trust") securing the performance of the Company under a $1.5 million
Promissory Note held by Midland Loan Services. The First Deed of Trust
provides for an interest rate of 9.5% per annum, a maturity date of December
2001, monthly payments of principal and interest of $13,736 and a balloon
payment at maturity. At December 31, 1997, the principal amount secured by the
First Deed of Trust was $1,456,586.
 
  The Company's Fremont property is also encumbered by a second deed of trust
(the "Second Deed of Trust") securing the performance of the Company under a
$400,000 Term Loan Agreement with Sanwa Bank California. The Term Loan
Agreement provides for a variable annual interest rate of prime plus 1.75%, a
maturity date of September 30, 2002, and monthly payments of principal and
interest of $6,667. At December 31, 1997, the principal amount secured by the
Second Deed of Trust was $379,999.
 
  The Company's Richland property is encumbered by a deed of trust (the
"Richland Deed of Trust") securing the payment by the Company of a $750,000
Promissory Note held by West One Bank (the "West One
 
                                      34
<PAGE>
 
Note"). 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. At
December 31, 1997, the principal balance secured by the Richland Deed of Trust
was $342,589. There are no encumbrances on the Company's Aiken, South Carolina
property.
 
  The Company believes that its existing and planned facilities will support
its operations for the foreseeable future and are adequately covered by
insurance.

BOARD OF DIRECTORS
   
  There are currently three members of the Board, with the number of directors
increasing to seven upon the consummation of the Offering. The directors serve
until the next annual meeting of shareholders or until successors are elected
and qualified. The Company's executive officers are appointed by and serve at
the discretion of the Board.     
 
  The Board has established an Audit Committee and a Compensation Committee.
The functions of the Audit Committee include recommending to the Board the
selection and retention of independent auditors, reviewing the scope of the
annual audit and the progress and results of the auditors' work, and reviewing
the Company's financial statements and internal accounting and auditing
procedures. The functions of the Compensation Committee include establishing
the compensation of the Chief Executive Officer, reviewing and approving
executive compensation policies and practices, reviewing salaries and bonuses
for certain executive officers, and considering such other matters as the
Board may, from time to time, delegate to the Compensation Committee.
 
  Each non-employee director will receive a cash fee of $2,000 per Board
meeting attended 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. The directors are reimbursed for expenses incurred in connection with
the performance of their services as directors.
 
Non-Employee Directors' Stock Option Plan
 
  In February 1998, the Board adopted the Company's 1998 Non-Employee
Directors' Stock Option Plan (the "Directors' Plan") to provide for the
automatic grant of options to purchase shares of Common Stock to non-employee
directors of the Company. The Directors' Plan is administered by the Board. To
date, no options have been granted under the Directors' Plan.
 
  The maximum number of shares of Common Stock that may be issued pursuant to
options granted under the Directors' Plan is 200,000. Pursuant to the terms of
the Directors' Plan, each person serving as a director of the Company who is
not an employee of the Company (a "Non-Employee Director") shall automatically
be granted an option to purchase 20,000 shares of Common Stock upon the later
of the date such person first becomes a Non-Employee Director or the date of
the effectiveness of the initial public offering of the Common Stock, 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 Directors' Plan must
equal or exceed the fair market value of the Common Stock on the date of
grant. No option granted under the Directors' Plan may be exercised after the
expiration of ten years from the date it was granted. Options granted under
the Directors' Plan are generally non-transferable except by will or by the
laws of descent and distribution. The Directors' Plan will terminate at the
discretion of the Board; provided, however, that in no event will the term of
the Directors' Plan extend beyond the tenth anniversary of its adoption by the
Board.
 
  In the event of certain changes of control of the Company (as defined in the
Directors' Plan), any outstanding options will automatically become fully
vested and will terminate if not exercised prior to such change of control.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION IN COMPENSATION
DECISIONS
 
  During its fiscal year ended December 31, 1997, the Company had no
compensation committee or other committee of the Board performing similar
functions, and all decisions concerning compensation of executive officers
were made by the Chairman of the Board. On January 14, 1998, the Board created
a Compensation Committee consisting of Doreen M. Chiu, Frank Y. Chiu and
Edward L. Vinecour. No interlocking relationship exists between any member of
the Company's Compensation Committee and any member of any other company's
board of directors or compensation committee. See "Management--Executive
Officers and Directors."

Executive Officer and the three other most highly compensated executive
officers of the Company whose total salary and bonus during such year exceeded

(1) Mr. Hewitt joined the Company in April 1997 at an initial annual base
    salary of $150,000. The amount of salary reflected in the table is the
    prorated amount paid to him in 1997.
 
  Steven J. Guerrettaz was appointed to the position of Chief Financial
Officer of the Company in December 1997, with an initial annual base salary of
$150,000. Options to purchase an aggregate of 60,000 shares of Common Stock,
at an exercise price of $5.00 per share, have been granted to Mr. Guerrettaz.
The options vest in four equal installments during the period beginning on
June 30, 1998 and ending on December 31, 2000, with accelerated vesting as to
options covering 10,000 shares upon an initial public offering of the Common
Stock and as to options covering 20,000 shares upon the Company's obtaining
specified financing for its LLMW treatment facility.
 
  Each of the Named Executive Officers receives perquisites and other personal
benefits from the Company, the aggregate amount of which during fiscal 1997
did not exceed the lesser of $50,000 or 10% of the annual base salary reported
for such Named Executive Officer. The Named Executive Officers did not receive
any additional compensation in fiscal 1997. To date, the Company has not made
any awards under its 1998 Stock Ownership Incentive Plan to any of the Named
Executive Officers or any other person. None of the Named Executive Officers
is a party to an employment agreement with the Company.

EMPLOYEE BENEFIT PLANS
 
 Stock Ownership Incentive Plan
 
  In February 1998, the Board adopted the Company's 1998 Stock Ownership
Incentive Plan (the "Incentive Plan"). The Incentive 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 Incentive Plan reserves for
issuance an aggregate of 500,000 shares of Common Stock, no more than 250,000
shares of which may be issued in the form of shares of restricted stock. The
Incentive Plan is intended to advance the interests of the Company by
encouraging the Company's employees who contribute to the Company's long-term
success and development to acquire and retain an ownership interest in the
Company. To date, no awards have been made under the Incentive Plan.
 
  The Incentive Plan will be administered by the Board. The Board will select
employees to receive awards under the Incentive 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 Incentive 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 Incentive 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 Incentive 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 the Company
must have an exercise price equal to at least 110% of such fair market value.
Optionees may exercise options under the Incentive Plan by paying cash, by
tendering shares of Common Stock, by using a cashless exercise procedure
provided for in the Incentive 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 the Company (as defined in the Incentive Plan),
any outstanding options become fully vested and immediately exercisable.
Options granted under the Incentive Plan are generally non-transferable except
by will or by the laws of descent and distribution. No option granted under
the Incentive 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 Company's Employee Stock Purchase
Plan (the "Purchase Plan") covering an aggregate of 200,000 shares of Common
Stock. The Purchase Plan is intended to qualify as an employee stock purchase
plan within the meaning of Section 423 of the Code. Under the Purchase Plan,
the Board may authorize participation by eligible employees of the Company,
including officers, in periodic offerings following the adoption of the
Purchase Plan. The offering period for any offering will be determined by the
Board, but in no event will be more than 27 months.
 
  Employees are eligible to participate if they are employed by the Company or
an affiliate of the Company 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
Purchase 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 Purchase 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 the Company.
 
  In the event of certain changes of control of the Company (as defined in the
Purchase 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
 
                                      41
<PAGE>
 
collected by payroll deductions to be applied to purchase stock immediately
prior to the change in control. The Purchase Plan will terminate at the
discretion of the Board.
 
 401(k) Plan
 
  In 1995, the Company established a tax-qualified employee savings and
retirement plan (the "401(k) 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 the Company, such matching and the amount of such matching to be
determined at the sole discretion of the Board. To date, no such matching
contributions have been made with respect 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 the Company when made.
 
LIMITATION ON DIRECTORS' LIABILITY
 
  The Company's Articles of Incorporation (the "Articles") 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 to 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 the Company 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 the Company 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 the Company 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.
 
  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 benefitted the Company and its
shareholders. The Company believes that it is the position of the Securities
and Exchange Commission (the "Commission") that insofar as the foregoing
provision 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. The Company believes that the
foregoing provision of its Articles is necessary to attract and retain
qualified persons as directors.

                             CERTAIN TRANSACTIONS
 
  The following is a summary of certain transactions to which the Company was
or is a party and in which certain executive officers, directors or
shareholders of the Company had or have a direct or indirect material
interest.
 
  From 1992 to 1997, Doreen M. Chiu, the Company's Chairman of the Board and
Chief Executive Officer, extended a series of loans to the Company, each of
which is repayable in full upon demand (collectively, the "Loan"). The Loan,
which is unsecured, bears interest at an annual rate of 10%, payable
concurrently with principal. The outstanding principal balance of the Loan,
including accrued interest, at December 31, 1997 was $1,280,180.
   
  Doreen M. Chiu and Frank Y. Chiu, the Executive Vice-President and a
director of the Company, have each guaranteed the obligations of the Company
under (i) a credit facility between the Company and Sanwa Bank California, up
to a maximum principal liability amount of $8,000,000; (ii) a Promissory Note
in the principal amount of $3,000,500 held by Safeco Credit Company, Inc.;
(iii) a Term Loan Agreement in the principal amount of $400,000 held by Sanwa
Bank California; (iv) an Equipment Lease between the Company and Great Western
Leasing that provides for an aggregate rental amount of $215,673; (v) an
Equipment Lease between the Company and The CIT Group/Equipment Financing,
Inc. that provides for an aggregate rental amount of $174,640; and (vi) a
Commercial Lease Agreement between the Company and California Thrift and Loan
with an aggregate rental amount of $125,767.     
   
  In connection with the sale by the Company of shares of Preferred Stock,
Doreen M. Chiu and Frank Y. Chiu entered into a Co-Sale and Put Option
Agreement with the Company and each purchaser of such shares (the "Co-Sale
Agreement"), pursuant to which Mr. and Mrs. Chiu are obligated to purchase
shares of the Preferred Stock from the holders in the event that the Company
fails to redeem such shares in accordance with the Company's Restated Articles
of Incorporation or in the event of a sale of Common Stock by Mr. and Mrs.
Chiu in contravention of the rights to participate pro rata in any such sale
conferred on such holders by the terms of the Co-Sale Agreement. The
obligations of Mr. and Mrs. Chiu to purchase shares of Preferred Stock under
the Co-Sale Agreement are secured by a security interest in certain of their
personal assets.     
 
  In connection with the repurchase by the Company of all of the shares of
Common Stock owned by him, Edward L. Vinecour, a director of the Company, in
1992 entered with the Company into (i) a Consultant Agreement, pursuant to
which, in consideration of certain future consulting services to be rendered
by Mr. Vinecour to the Company, the Company agreed to pay him consulting fees
in a monthly amount of $5,000 for a period of 10 years commencing in August of
1992 and assumed the payment obligations under a mortgage loan with a then
remaining principal balance of $146,351, requiring monthly mortgage payments
of $1,816 over a period of 15 years, and (ii) a Non-Competition Agreement,
pursuant to which, in consideration of Mr. Vinecour's agreement not to compete
with the business of the Company, the Company agreed to pay him the sum of
$290,000 in installments. Of the original sum of $290,000 due to Mr. Vinecour
under the Non-Competition Agreement, $65,000 has been paid by the Company as
of December 31, 1997, with Mr. Vinecour agreeing to extend payment of the
entire balance until the year 2000.
   
  In connection with the issuance of certain bonds, undertakings and other
instruments of guarantee in favor of the Company, Doreen M. Chiu and Frank Y.
Chiu have each executed (i) a blanket Indemnity Agreement in favor of ACTSTAR
Insurance Company ("ACTSTAR"), indemnifying ACTSTAR against any losses that
ACTSTAR 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 Company, 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,
1997, the potential aggregate liability of Mr. and Mrs. Chiu under these
blanket indemnities was approximately $7 million.     
 
  The Company believes that each of the foregoing transactions was on terms at
least as favorable to the Company as those that could have been obtained from
nonaffiliated third parties. The Company currently intends that any future
transactions with affiliates of the Company will be on terms at least as
favorable to the Company as those that can be obtained from nonaffiliated
third parties.

                         DESCRIPTION OF CAPITAL STOCK
   
  The following description of the capital stock of the Company and material
provisions of the Articles is a summary and is qualified in its entirety by
the provisions of the Articles, which have been filed as an exhibit to the
Company's Registration Statement of which this Prospectus is a part.     
 
  The authorized capital stock of the Company currently consists of 20,000,000
shares of Common Stock, no par value per share ("Common Stock"), of which
7,532,301 shares are currently outstanding, and 1,000,000 shares of Preferred
Stock, of which 900,000 shares are currently outstanding. As of December 31,
1997, there were 66 record holders of the 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 the Company's
directors. Subject to preferences that may be applicable to any shares of
preferred stock issued in the future, holders of Common Stock are entitled to
receive ratably such dividends as may be declared by the Board out of funds
legally available therefor. See "Dividend Policy." In the event of a
liquidation, dissolution or winding up of the Company, holders of the Common
Stock are entitled to share ratably with the holders of any then outstanding
preferred stock in all assets 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, and all shares of Common Stock to be outstanding upon completion of
the Offering will be, fully paid and nonassessable.     
 
PREFERRED STOCK
   
  The following is a brief summary of the material rights, preferences,
privileges, restrictions and limitations of the outstanding shares of
Preferred Stock.     
 
  Dividends. Any dividends declared by the Board are to be distributed pari
passu among all holders of Preferred Stock and all holders of Common Stock in
proportion to the number of shares of Common Stock which would be held by each
such holder if all shares of Preferred Stock were converted into Common Stock
at the then effective Conversion Price (as defined below).
 
  Liquidation Preference; Right of First Offer. In the event of a liquidation,
dissolution or winding up of the Company, the holders of Preferred Stock are
entitled to a cash payment equal to the Liquidation Value (as defined below)
of each share held, before any distribution of the Company's assets to holders
of the Common Stock. The "Liquidation Value" per share means an amount equal
to (i) $5.00 plus (ii) a premium equal to an annual rate of ten percent (10%)
of such amount compounded annually from the date the share was issued (the
"Issue Date"), plus (iii) all declared but unpaid dividends thereon. Each
holder of Preferred Stock has certain rights of first offer to subscribe for
new issuances of securities by the Company (not including securities offered
to the public pursuant to a registration statement filed under the Securities
Act).
 
  Voluntary Conversion. Each share of Preferred Stock is, at the option of the
holder, convertible into such number of shares as results from dividing $5.00
by the Conversion Price then in effect. The initial Conversion Price is $5.00,
subject to adjustments for subsequent dilutive issuances of securities by the
Company. In addition, the Conversion Price is specifically adjusted upon the
closing of an underwritten public offering of the Common Stock after July 1,
1996 to the lower of (i) the then current Conversion Price and (ii) the price
determined by multiplying the price to the public in such underwriting by .25.
The Conversion Price is currently $5.00.
 
                                      45
<PAGE>
 
  Automatic Conversion. Immediately prior to the closing of a firm commitment,
underwritten public offering of the Common Stock having an aggregate price to
the public of not less than $12 million and closing on or prior to June 30,
1998, each share of Preferred Stock is automatically converted into 1 2/3
shares of Common Stock. Each such share is also automatically converted into
shares of Common Stock at the then effective Conversion Price at the election
of the holders of a majority of the outstanding shares of Preferred Stock.
 
  Redemption. Commencing on or about the third anniversary of the Issue Date,
each holder of Preferred Stock will have the right to demand that the Company
redeem all or any part of the shares of Preferred Stock held by him at a
redemption price per share consisting of a base redemption price of $6.67,
plus any declared but unpaid dividends thereon.
 
  Voting Rights. Except as otherwise required by law and as to certain matters
set forth in the Articles as requiring the prior affirmative vote or written
consent of the holders of not less than a majority of the outstanding shares
of Preferred Stock, the Preferred Stock is non-voting. The matters set forth
in the Articles include (i) the payment by the Company of cash dividends, (ii)
the redemption or repurchase by the Company of any of the Common Stock (other
than from employees, officers, directors and consultants of the Company upon
the termination of their relationship with the Company), (iii) the sale of all
or substantially all of the assets of the Company or the consummation by the
Company of any transaction or series of transactions resulting in a change of
control of the Company, and (iv) the Company's incurrence of any indebtedness
or grant of any security interest in any of the Company's assets, other than
in connection with equipment leases entered into in the ordinary course of
business, a revolving credit line from a commercial bank that does not exceed
80% of eligible accounts receivable or the refinancing of existing mortgages.
 
  Registration Rights. Pursuant to the terms of a Shareholder Rights Agreement
between the Company and each purchaser of Preferred Stock, if the Company
determines to register any of its securities (other than a registration
relating solely to employee benefit plans or a transaction covered by Rule 145
promulgated under the Securities Act), then the holders of Preferred Stock
have piggyback registration rights to cause the Company to include the shares
of Common Stock issued upon conversion of the Preferred Stock (the
"Registrable Shares") to be included in the related registration statement (a
"Piggyback Registration"). The Company may, however, reduce on a pro rata
basis, to the extent so advised by the underwriters of the offering, the
amount of Registrable Shares to be included in any such registration.
Additionally, the holders of an aggregate of at least 300,000 Registrable
Shares (as adjusted for stock splits or reverse stock splits), or a lesser
number, if the offering thereof results in aggregate proceeds (net of selling
expenses) exceeding $15 million, have a demand right on two separate occasions
to cause the Company to register such Registrable Shares, and each holder of
Registrable Shares has the additional right on an unlimited number of
occasions, subject to certain timing limitations, to cause the Company to
register his Registrable Shares on Form S-3 under the Securities Act, if the
aggregate price to the public of the shares offered thereby exceeds $1.5
million (each, a "Demand Registration"). The Company is obligated to pay all
registration expenses (other than underwriting discounts and commissions and
subject to certain limitations) incurred by virtue of including shares of
Common Stock subject to such registration rights in either a Demand
Registration or Piggyback Registration.
 
OTHER CONVERSION RIGHTS
 
  Immediately prior to the closing of a firm commitment, underwritten public
offering of the Common Stock having an aggregate price to the public of not
less than $12 million and closing on or prior to June 30, 1998, each
outstanding share of the Series A and Series B Redeemable Non-Voting Preferred
Stock issued by ATG Richland is automatically converted into Common Stock at a
stated conversion ratio of one share of Series A Redeemable Non-Voting
Preferred Stock into 1.4119814 shares of Common Stock and one share of Series
B Redeemable Non-Voting Preferred Stock into 1 share of Common Stock. As of
December 31, 1997, 860,000 shares of Series A Redeemable Non-Voting Preferred
Stock and 1,269,291 shares of Series B Redeemable Non-Voting Preferred Stock
were outstanding.
 
 
                                      46
<PAGE>
 
OTHER REGISTRATION RIGHTS
 
  As parties to certain portions of the Shareholder Rights Agreement between
the Company and each purchaser of Preferred Stock, certain holders of Common
Stock have acquired piggyback registration rights, with respect to all shares
of Common Stock owned by them, identical to those held by the purchasers of
Preferred Stock with respect to the Registrable Shares owned by them. Certain
other holders of Common Stock who are not parties to certain portions of the
Shareholder Rights Agreement have piggyback registration rights, with respect
to all shares of Common Stock owned by them, similar to the piggyback
registration rights held by the purchasers of the Preferred Stock.
 
OPTIONS
 
  At December 31, 1997, options to purchase up to 1,000,000 shares of Common
Stock, at a weighted average exercise price of $2.09, were outstanding,
298,927 of which were exercisable on such date.
 
OVER-ALLOTMENT OPTION AND REPRESENTATIVE'S WARRANTS
 
  The Company has granted the Underwriters an over-allotment option, pursuant
to which the Underwriters have the right, exercisable during the 45-day period
after the date of this Prospectus, to purchase up to 255,000 additional shares
of Common Stock from the Company at the same price per share as the Company
will receive for the 1,700,000 shares that the Underwriters have agreed to
purchase in the Offering. In addition, the Company has agreed to issue to Van
Kasper & Company, as the Representative, for nominal consideration, the
Representative's Warrants, pursuant to which the Representative will have the
right, exercisable for a period of four years beginning one year from the date
of this Prospectus, to purchase up to 170,000 shares of Common Stock at an
exercise price per share equal to 120% of the initial public offering price of
the Offering. See "Underwriting."
 
TRANSFER AGENT AND REGISTRAR
   
  The transfer agent and registrar for the Common Stock is U.S. Stock Transfer
Corporation.

<PAGE>
 
                        SHARES ELIGIBLE FOR FUTURE SALE
   
  Upon completion of the Offering, the Company will have 13,215,896 shares of
Common Stock outstanding (assuming no exercise of outstanding stock options
after December 31, 1997). Of these shares, the 1,700,000 shares sold in the
Offering will be freely tradeable without restriction or registration under
the Securities Act unless they are held by "affiliates" of the Company, as
that term is defined in Rule 144. The remaining 11,515,896 shares will be
"restricted securities" as defined in Rule 144 ("Restricted Shares"). Of such
Restricted Shares, 9,590,841 shares may not be sold without the consent of Van
Kasper & Company for 180 days after the date of this Prospectus, and 8,248,201
of such shares are subject to certain conditions on sale for an additional 180
days. As a result of the lock-up agreements and the provisions of Rule 144(k)
and Rule 144 generally, all currently outstanding shares will be available for
sale in the public market 180 days after the date of this Prospectus, subject
to the provisions of Rule 144 and, as to 8,248,201 of such shares, certain
conditions on sale for an additional 180 days. See "Underwriting."     
 
  In general, under Rule 144 as currently in effect, any person (or persons
whose shares are aggregated) who has beneficially owned Restricted Shares for
at least one year is entitled to sell, within any three-month period, a number
of such shares that does not exceed the greater of (i) 1.0% of the then
outstanding shares of the Common Stock (approximately 132,159 shares
immediately after the Offering) and (ii) the average weekly trading volume
during the four calendar weeks preceding such sale. Sales under Rule 144 are
also currently subject to certain requirements as to the manner of sale,
notice and availability of current public information about the Company. Rule
144 also provides that affiliates who own securities that are not Restricted
Shares must nonetheless comply with the same restrictions applicable
thereunder to Restricted Shares, as if such securities were Restricted Shares,
with the exception of the one-year holding period requirement. A person who
has not been an affiliate of the Company at any time within three months prior
to the sale and has beneficially owned the Restricted Shares for at least two
years is entitled to sell such shares under Rule 144(k) without regard to the
volume limitations or any of the other requirements described above.
 
  An employee, officer or director of or consultant to the Company who
purchased or was awarded shares or options to purchase shares pursuant to a
written compensatory plan or contract is entitled to rely on the resale
provisions of Rule 701 promulgated under the Securities Act, which permits
affiliates and non-affiliates to sell their Rule 701 shares without having to
comply with Rule 144's holding period restrictions, in each case commencing 90
days after the date of this Prospectus. In addition, non-affiliates may sell
Rule 701 shares without complying with the public information, volume and
notice provisions of Rule 144.
 
  The Company intends to file with the Commission registration statements on
Form S-8 under the Securities Act to register the shares of Common Stock
reserved for issuance under the Incentive Plan, the Directors' Plan and the
Purchase Plan, thus permitting the resale of shares issued under such plans by
non-affiliates in the public market without restriction under the Securities
Act. Such registration statements will be filed at management's discretion
following the closing of the Offering and will be automatically effective upon
filing.
 
  Prior to the Offering, there has been no public market for the Common Stock,
and any sale of substantial amounts of Common Stock in the open market may
adversely affect the market price of Common Stock offered hereby.

  The shares of Common Stock are being offered by the Underwriters named
herein, subject to their right to reject any order in whole or in part, and to
certain other conditions. The Underwriters are committed to purchase all of
the above shares of Common Stock if any are purchased.
 
  The Representative has advised the Company that the Underwriters propose to
offer the shares of Common Stock at the offering price set forth on the
outside front cover page of this Prospectus: (i) to the public; and (ii) to
certain dealers at that price less a concession of not more than $0.   per
share, of which a discount of $0.   may be reallowed to other dealers. After
the consummation of the Offering, the public offering price, concession and
reallowance to dealers may be changed by the Representative as a result of
market conditions and other factors. No such change shall affect the amount of
proceeds to be received by the Company as set forth on the outside front cover
page of this Prospectus.
 
  The Company has granted the Underwriters the over-allotment option, pursuant
to which the Underwriters have the right, exercisable during the 45-day period
after the date of this Prospectus, to purchase up to 255,000 additional shares
of Common Stock from the Company at the initial offering price, less
underwriting discounts. The Underwriters may exercise such option only to
cover over-allotments made in connection with the sale of Common Stock offered
hereby. To the extent that the Underwriters exercise such option, each of the
Underwriters will have a firm commitment to purchase approximately the same
percentage of the additional Common Stock that the number of shares of Common
Stock to be purchased by the Underwriter set forth in the above table bears to
the total number of shares of Common Stock listed in such table.
   
  Upon completion of the Offering, the Company has agreed to sell to the
Representative, for nominal consideration, the Representative's Warrants,
pursuant to which the Representative will have the right to purchase up to
170,000 shares of Common Stock at an exercise price per share equal to 120% of
the initial public offering price. The Representative's Warrants are
exercisable for a period of four years beginning one year from the date of
this Prospectus. The Representative's Warrants will be restricted from
transfer for a period of one year from the date of this Prospectus, except for
transfers to officers or partners of the Representative and members of the
selling group. The Representative's Warrants will contain provisions providing
for adjustment of exercise price and number and type of securities issuable
upon exercise should one or more of certain specified events occur, including
the Company's declaration of a stock dividend, a split or reverse split of the
Common Stock, reclassification of the Common Stock, the Company's distribution
of property to all holders of the Common Stock and the issuance to all such
holders of rights or warrants to purchase Common Stock at an exercise price
less than the then current market value. In addition, the Company has granted
certain rights to the holders of the Representative's Warrants to register the
Representative's Warrants and the Common Stock underlying the Representative's
Warrants under the Securities Act.     
 
  The Company has agreed to pay the Representative a non-accountable expense
allowance equal to 1.5% of the total proceeds of the Offering (including with
respect to shares of Common Stock underlying the over-
 
                                      49
<PAGE>
 
allotment option, if and to the extent it is exercised) for expenses in
connection with the Offering, payable at the close of the Offering.
 
  The Underwriting Agreement contains covenants of indemnity among the
Underwriters and the Company against certain civil liabilities, including
liabilities under the Securities Act.
   
  The Company's officers and directors and certain beneficial owners of the
Common Stock have agreed not to, directly or indirectly, offer to sell,
contract to sell, sell or otherwise dispose of any shares of Common Stock or
any securities convertible into or exchangeable for shares of Common Stock or
any rights to purchase or acquire Common Stock for the 180-day period
commencing with the date of this Prospectus (the "lock-up period") without the
prior written consent of Van Kasper & Company, and, in certain cases, that
they will only sell subject to certain conditions on sale for an additional
period of 180 days thereafter. All 9,590,841 shares of Common Stock subject to
the lock-up agreements will become eligible for immediate public sale
following expiration of the lock-up period, subject to the provisions of the
Securities Act, the rules promulgated thereunder, including Rule 144, and, as
to 8,248,201 of such shares, certain conditions on sale for an additional
period of 180 days. Van Kasper & Company may, in its sole discretion, and at
any time without notice, release all or a portion of the securities subject to
the lock-up agreements. In addition, the Company has agreed that until the
expiration of the lock-up period, the Company will not, without the prior
written consent of Van Kasper & Company, offer, sell, contract to sell or
otherwise dispose of any shares of Common Stock, any options or warrants to
purchase Common Stock or any securities convertible into or exchangeable for
shares of Common Stock, except for sales of shares of Common Stock in the
Offering, the issuance of shares of Common Stock upon the exercise of
outstanding options, warrants and rights or pursuant to the conversion of all
of the outstanding shares of the Preferred Stock and of ATG Richland's Series
A and Series B Redeemable Non-Voting Preferred Stock into an aggregate of
3,983,595 shares of Common Stock, and the grant of options to purchase or the
issuance of shares of Common Stock under the Incentive Plan, the Directors'
Plan or the Purchase Plan.     
 
  The Representative has advised the Company that, pursuant to Regulation M
promulgated under the Securities Exchange Act of 1934, as amended, certain
persons participating in the Offering may engage in transactions, including
stabilizing bids, syndicate covering transactions or the imposition of penalty
bids, which may have the effect of stabilizing or maintaining the market price
of the Common Stock at a level above that which might otherwise prevail in the
open market. A "stabilizing bid" is a bid for or the purchase of the Common
Stock on behalf of the Underwriters for the purpose of pegging, fixing or
maintaining the price of the Common Stock. A "syndicate covering transaction"
is the bid for or the purchase of the Common Stock on behalf of the
Underwriters to reduce a short position created in connection with the
Offering. The Underwriters may also cover all or a portion of such short
position by exercising the over-allotment option. A "penalty bid" is an
arrangement permitting the Representative to reclaim the selling concession
otherwise accruing to an Underwriter or syndicate member in connection with
the Offering if the Common Stock originally sold by such Underwriter or
syndicate member is purchased by the Representative in a syndicate covering
transaction and has therefore not been effectively placed by such Underwriter
or syndicate member. The Representative has advised the Company that such
transactions may be effected on the Nasdaq National Market or otherwise and,
if commenced, may be discontinued at any time.
 
  The Representative has advised the Company that the Underwriters do not
intend to confirm sales to any accounts over which they exercise discretionary
authority.
 
  Prior to the Offering, there has been no public market for the Company's
securities. The initial public offering price of the Common Stock was
determined by negotiations between the Company and the Representative. Among
the factors considered in such negotiations were prevailing market conditions,
the results of operations of the Company in recent periods, market valuations
of publicly traded companies that the Company and the Representative believe
to be comparable to the Company, estimates of the business potential of the
Company, the present state of the Company's development, the current state of
the Company's industry and the economy as a whole, and other factors deemed
relevant by the Company and the Representative.

                                    EXPERTS
 
  The Consolidated Financial Statements of the Company as of December 31, 1996
and 1997, and for each of the three years in the period ended December 31,
1997, included in this Prospectus, have been included herein in reliance on

accountants from SC&S to Coopers & Lybrand L.L.P. was effective for fiscal
1995, was unanimously approved by the Board and was not due to any
disagreements between the Company and SC&S on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedures.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders
ATG Inc. and Subsidiary:
 
  We have audited the accompanying consolidated balance sheets of ATG Inc. and
its subsidiary as of December 31, 1996 and 1997, and the related consolidated
statements of operations, shareholders' equity and cash flows for each of the
three years in the period ended December 31, 1997. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of ATG Inc. and
its subsidiary as of December 31, 1996 and 1997 and the consolidated results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1997, in conformity with generally accepted
accounting principles.

To the Board of Directors and Shareholders of ATG Inc. and Subsidiary:
 
  The consolidated financial statements and notes thereto included herein have
been adjusted to give effect to the proposed conversion of the ATG Inc. Series
A Preferred Stock, ATG Richland Series A Preferred Stock and ATG Richland
Series B Preferred Stock into 3,983,595 shares of common stock of ATG Inc.,
which is more fully described in Note 16 to the financial statements. The
above report is in the form that will be signed by Coopers & Lybrand L.L.P.
upon obtaining the approval of the preferred shareholders for the revised
conversion ratios, assuming that from January 31, 1998 to the effective date
of such conversion, no other events shall have occurred that would affect the
accompanying consolidated financial statements or notes thereto.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
           (all dollar amounts in thousands, except per share data)
                                   --------
 
1. FORMATION AND BUSINESS OF THE COMPANY:
 
  The accompanying consolidated financial statements of ATG Inc. (the
"Company" or "ATG") include the accounts of its wholly-owned subsidiary, ATG
Richland Corporation ("ATG Richland"). The Company 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 and other hazardous
waste, site remediation and fluorescent lamp recycling.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Basis of Presentation
 
  The consolidated financial statements include the accounts of ATG and its
wholly-owned subsidiary. 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 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 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 includes estimated fees earned according to the terms of the
contracts. Revenue from U.S. government contracts includes estimates of
reimbursable overhead and general and administrative expenses, which are
subject to final determination by the U.S. federal government upon project
completion. Revisions to costs and income resulting from contract settlements,
which are due to differences between actual and budgeted performance, are
recognized in the period in which the revisions are determined. Revenue from
waste processing is generally recognized upon the completion of the waste
treatment process. Revenue relating to contract change orders is not
recognized until acceptance of the change orders is probable. Revenue from
licensing or technology transfer agreements is recognized when received unless
there are future commitments, in which case the revenues are recognized over
the term of the agreement. Revenues of $1,975 were recognized pursuant to
technology transfer agreements in 1997. Losses on contracts are charged to
cost of revenue as soon as such losses become known.     
 
 Cash and Cash Equivalents
 
  The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.
 
 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 fifteen years. Cost includes expenditures for major

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
           (all dollar amounts in thousands, except per share data)
                                   --------
improvements and replacements and the net amount of interest costs related to
qualifying construction projects. Expenditures for major renewals and
betterments are capitalized and 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.
 
 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
is no assurance of the outcome of any permitting efforts. The permitting
process is subject to regulatory approval, time delays, local opposition and
potentially stricter governmental regulation. Substantial losses which would
have a material adverse effect on the Company's consolidated financial
position, could be incurred by the Company in the event a permit is not
granted, if facility construction programs are delayed or changed, or if
projects are otherwise abandoned. The Company reviews the status of permitting
projects on a periodic basis to assess realizability of related asset values.
As of December 31, 1997, 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 largely on governmental authorities. 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
 
  The Company accounts for income taxes under the liability method, whereby
deferred tax assets and liabilities are determined based on the difference
between the financial statement and tax bases of assets and liabilities using
enacted tax rates in effect for the year in which the differences are expected
to affect taxable income. Valuation allowances are established when necessary
to reduce deferred tax assets to the amounts expected to be realized.
 
 Concentration of Credit Risk
 
  The majority of the Company's cash, cash equivalents and short-term
investments are held with major banks in the United States. The Company's
customers mainly consist 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, 1997, agencies of the U.S. government
represented 46.6% of accounts receivable and 71.3% of total revenue for the
year then ended. As of December 31, 1996, agencies of the U.S. government
represented 70.0% of accounts receivable and 76.8% of total revenue for the
year then ended. As of December 31, 1995, agencies of the U.S. government
represented 84.0% of accounts receivable and 86.3% of total revenue for the
year then ended. The Company generally does not require collateral.
 
 Computation of Pro Forma Net Income Per Share
 
  The Company has adopted the provisions of Statement of Financial Accounting
Standards No. 128, Earnings Per Share ("SFAS 128"), effective December 31,
1997. SFAS 128 requires the presentation of basic and diluted earnings 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. Dilutive
potential common shares consist of the incremental common shares issuable upon
the conversion of convertible preferred stock (using the "if converted"
method) and exercise of stock options for all periods. Pro forma basic net
income per share and pro forma diluted net income per share are computed using
the weighted average number of shares of Common Stock outstanding and the
incremental inclusion of 3,983,595 shares of common stock issuable upon the
conversion of preferred stock.
 
 Unaudited Pro Forma Consolidated Balance Sheet
 
  Upon closing of the Company's proposed initial public offering, all
outstanding shares of mandatorily redeemable preferred stock will be converted
into 3,983,595 shares of common stock. (See Note 16.) The unaudited pro forma
consolidated balance sheet as of December 31, 1997, reflects this conversion.
Accretion of $3,958 has been reclassified from pro forma mandatorily
redeemable preferred stock to pro forma accumulated deficit.
 
 Recent Accounting Pronouncements
 
  In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130, "Reporting Comprehensive Income." SFAS No. 130 establishes standards
for the reporting and display of comprehensive income and its components in a
full set of general purpose financial statements. Comprehensive income is
defined as the change in equity of a business enterprise during a period,
resulting from transactions and other events and circumstances from nonowner
sources. The Company is reviewing the impact of adopting SFAS No. 130, which
is effective for the Company in 1998.
 
  In June, 1997, the FASB issued SFAS No. 131, "Disclosure about Segments of
an Enterprise and Related Information." SFAS No. 131 requires publicly-held
companies to report financial and other information about key revenue-
producing segments of the entity for which such information is available and
is utilized by the chief operating decision maker. Specific information to be
reported for individual segments includes profit or loss, certain revenue and
expense items and total assets. A reconciliation of segment financial
information to amounts reported in the financial statements would be provided.
SFAS No. 131 is effective for the Company in 1998. The Company currently
evaluates its operations as one segment.

  Recoverable costs and accrued profit on progress completed but not billed on
U.S. government contracts is based on estimates of reimbursable overhead and
general and administrative expenses calculated in accordance with
contractually determined methods of calculation. These amounts are subject to
final determination by the U.S. federal government after the contracts have
been completed. As such, the actual recoverable amounts on these contracts may
differ from these estimates. The U.S. federal government has reviewed and
approved reimbursable expenses for contracts in progress through 1995.

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

  The Company retained the services of a former shareholder, who is also a
current director, as a technical consultant, for the ten year period beginning

  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.

  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 will be amortized over the vesting period relating
to these options, of which $117 has been amortized during the year ended
December 31, 1997, and is included in the statement of operations within the
caption "Stock-based compensation expense".
 
 Stock Compensation
 
  Effective January 1, 1996 the Company has adopted the disclosure-only
provision of Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation" (SFAS No. 123). The Company, however, applies
APB Opinion No. 25, "Accounting for Stock Issued to Employees" and related
interpretations in accounting for its stock-based compensation. Determination
of compensation cost for stock-based compensation based on the fair value of
the grant date for awards consistent with provisions of SFAS No. 123 would not
result in a significant difference from the reported net income for the
periods presented.

  The fair value of each option grant for the Plan is estimated on the date of
the grant using the Black-Scholes option-pricing model with weighted average
risk free interest rates of 6.47% and 6.16% in 1996 and 1997, respectively,
and an expected life of 5 years, no dividends and 0% volatility in all
periods.

 Restricted Stock
 
  During 1992, 1993 and 1994, the Company agreed to issue at no cost a total
of 1,013,475 common shares to its majority shareholder and president. The
agreement required that the shareholder/president remain employed by the
Company through December 31, 1996. Deferred compensation expense represents
the difference between the issue price of the restricted stock and the deemed
fair value of the shares for financial statement purposes. Deferred
compensation was amortized over the employment period during which the shares
were restricted. Compensation expense of $169 was recognized in both 1995 and
1996.
 
12. MANDATORILY REDEEMABLE PREFERRED STOCK:
 
  ATG issued 900,000 shares of Series A Preferred Stock in 1994 at $5.00 per
share. ATG Richland issued 860,000 shares of Series A Preferred Stock in 1995
at $5.00 per share and 990,355 and 278,936 shares of Series B Preferred Stock
in 1996 and 1997, respectively, at $6.00 per share, under the following terms
and conditions:
   
  Upon the written request of the holders of the Preferred Stock, but not
before the fifth anniversary of the issue date (third anniversary in the case
of the ATG Richland Series B Preferred Stock), the issuing corporation is
required to redeem the Preferred Stock held by holders thereof requesting such
redemption. The redemption price is $6.67 for ATG Series A Preferred Stock and
ATG Richland Series A Preferred Stock and $8.00 for ATG Richland Series B
Preferred Stock. The dividends accrete based on the effective interest method.
    
  In the event of liquidation, dissolution or winding up of the issuing
corporation, the holders of Preferred Stock are entitled to a distribution in
preference to holders of Common Stock of the issuing corporation, equivalent
to the issue price plus a premium equal to 10% interest from the date of the
issue. If funds are insufficient for full payment of these amounts, the entire
assets and funds of the issuing corporation legally available are distributed
ratably among the holders of Preferred Stock. Certain property and equipment
has been provided as collateral for the Company's Series A Preferred Stock
issued in 1994.
 
  Any dividends declared by the issuing corporation are to be distributed pari
passu among all holders of its Preferred Stock and all holders of its Common
Stock in proportion to the number of shares of Common Stock which would be
held by each such holder if all classes of Preferred Stock were converted into
Common Stock at the then effective conversion price.

  Except as otherwise required by law and as to certain matters set forth in
the issuing corporation's articles of incorporation as requiring the prior
affirmative vote or written consent of the holders of not less than a majority
of the outstanding shares of Preferred Stock, the Preferred Stock is non-
voting.
 
  The shares of each series of Preferred Stock are automatically converted
under defined circumstances into shares of the Company's Common Stock at
specified conversion ratios upon the occurrence of an initial public offering
of such Common Stock.

a discretionary contribution. To date the Company has not made contributions
to the 401(k) Plan.

16. SUBSEQUENT EVENTS:
 
  In February 1998, the Company's Board of Directors ("the Board") authorized
the filing of a registration statement with the Securities and Exchange
Commission for the Company's initial public offering (the "Offering") of its
common stock. The Company and preferred shareholders agreed that all
outstanding shares of ATG Series A Preferred Stock and ATG Richland Series A
and Series B Preferred Stock automatically convert into 3,983,595 shares of
common stock of the Company upon completion of the Offering, assuming the
Offering gross proceeds are not less than $12,000 and the Offering is
completed on or prior to June 30, 1998. Such conversion is reflected in the
unaudited pro forma shareholders equity at December 31, 1997 in the
accompanying consolidated balance sheet. The underwriters of the public
Offering have been granted warrants, exercisable for a period of four years
beginning one year from the Offering date, to purchase up to 170,000 shares of
common stock at an exercise price per share equal to 120% of the initial
offering price to the public.
 
  In February 1998, the Board approved the Company's Employee Stock Purchase
Plan ("the Purchase Plan") covering an aggregate of 200,000 shares of common
stock. The Purchase Plan is intended to qualify as an employee stock purchase
plan within the meaning of Section 423 of the Internal Revenue Code of 1986.
Under the Purchase Plan, the Board may authorize participation by eligible
employees of the Company, including officers, in periodic offerings following
the adoption of the Purchase Plan.
 
  In February 1998, the Board adopted the Company's 1998 Stock Ownership
Incentive Plan (the "Incentive Plan"). The Incentive 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 Incentive Plan reserves for
issuance an aggregate of 500,000 shares of Common Stock, no more than 250,000
shares of which may be issued in the form of shares of restricted stock. The
Incentive Plan is intended to advance the interests of the Company by
encouraging the Company's employees who contribute to the Company's long-term
success and development to acquire and retain an ownership interest in the
Company. To date, no awards have been made under the Incentive Plan.
 
  Stock options granted pursuant to the Incentive Plan may either be incentive
stock options ("ISOs") intended to qualify under Section 422 of the Internal
Revenue Code of 1986, as amended, or stock options not intended to so qualify.
 
  In February 1998, the Board adopted the Company's 1998 Non-Employee
Directors' Stock Option Plan (the "Directors' Plan") to provide for the
automatic grant of options to purchase shares of Common Stock to non-employee
directors of the Company. The Directors' Plan is administered by the Board. To
date, no options have been granted under the Directors' Plan.
 
  The maximum number of shares of Common Stock that may be issued pursuant to
options granted under the Directors' Plan is 200,000. Pursuant to the terms of
the Directors' Plan, each person serving as a director of the Company who is
not an employee of the Company (a "Non-Employee Director") shall automatically
be granted an option to purchase 20,000 shares of Common Stock upon the later
of the date such person first becomes a Non-Employee Director or the date of
the effectiveness of the initial public offering of the Common Stock, 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.
   
  In February 1998, the revolving credit facility described in Note 7 was
amended such that the Company may borrow up to the lesser of 90% of eligible
accounts receivable or $5,000. Certain of the covenants described in Note 7
were also amended.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The Company's Articles of Incorporation ("Articles") 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 the Company 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 the Company 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 the Company 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 ("Section 317") 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 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.
 
                                     II-1
<PAGE>
 
  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.
 
  The Underwriting Agreement to be filed as Exhibit 1.1 to this Registration
Statement provides for indemnification by the Underwriters of the Company and
its officers and directors for certain liabilities arising under the
Securities Act or otherwise.
 
  The Company 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
 
  Except as set forth in this item, no securities of the Registrant have been
sold by the Registrant since January 1, 1994 without registration under the
Securities Act.
 
  In February 1994, the Company sold 900,000 shares of its Series A Preferred
Stock for an aggregate purchase price of $4,500,000 to a number of Taiwanese
investors and Taiwanese expatriates in the United States. The Company employed
the services of a private placement agent to whom it paid a placement fee of
5% in connection with this transaction.
 
  In March 1995, the Company's subsidiary, ATG Richland Corporation ("ATG
Richland"), sold 860,000 shares of its Series A Redeemable Non-Voting
Preferred Stock for an aggregate purchase price of $4,300,000 to a number of
Taiwanese investors and Taiwanese expatriates in the United States. The
Company employed the services of a private placement agent to whom it paid a
placement fee of 5% in connection with this transaction.
 
  In June 1996, ATG Richland sold 990,355 shares of its Series B Redeemable
Non-Voting Preferred Stock for an aggregate purchase price of $5,942,130 to a
number of Taiwanese investors and Taiwanese expatriates in the United States.

Non-Voting Preferred Stock for an aggregate purchase price of $1,673,616 to a

  The Company believes that the issuances of preferred stock described above
were exempt from the registration requirements of the Securities Act, by
virtue of Section 4(2) thereof and/or Regulation S promulgated under the
Securities Act ("Regulation S"). The Company believes that the issuances of
options described above were exempt from the registration requirements of the
Securities Act by virtue of Section 4(2) thereof or because the issuances of
such options did not involve the "sale," as such term is defined in Section
2(3) of the Securities Act, of a security.
   
  In March 1998, the Company sought and received shareholder approval to amend
its Articles of Incorporation and those of ATG Richland to modify the terms of
the conversion rights attached to the Preferred Stock authorized to be issued
by each such entity. The Company did not pay or give, directly or indirectly,
any commission or other remuneration in connection with seeking such approval.
The Company believes that any offer and sale of Common Stock deemed to occur
in connection with the modification of such rights was exempt from the
registration requirements of the Securities Act by virtue of Section 3(a)(9)
thereof and/or Regulation S.

ITEM 17. UNDERTAKINGS
 
  (a) The undersigned Registrant hereby undertakes to provide to the
Underwriters at the closing specified in the Underwriting Agreement
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.
 
  (b) Insofar as indemnification for liabilities arising under the Securities
Act 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
Securities 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 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 of
whether such indemnification by it is against public policy as expressed in
the Securities Act and will be governed by the final adjudication of such
issue.
 
  (c) The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  Rule 497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus 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.

                           CERTIFICATE OF AMENDMENT OF
                            ARTICLES OF INCORPORATION
                                       OF
                                    ATG INC.,
                            a California Corporation



     Doreen M. Chiu and Frank Y. Chiu certify that:


         1. They are the duly elected President and Secretary, respectively, of
ATG Inc., a California corporation (the "Corporation").

         2. The second paragraph of Section (b)(3)(a) of Article III of the
Amended and Restated Articles of Incorporation of the Corporation (the
"Articles") is amended to read as follows, in its entirety:

         "Subject to the following sentence, each share of Series A Preferred
         Stock shall be automatically converted into shares of Common Stock at
         the then effective Conversion Price (i) upon the effectiveness of a
         firm commitment underwritten public offering pursuant to an effective
         registration statement under the Securities Act of 1933, as amended,
         covering the offer and sale of Common Stock for the account of the
         Corporation to the public at a price per share of at least $10.00 (as
         adjusted for stock splits, reverse stock splits and the like effected
         after the date on which the first share of Series A Preferred Stock is
         issued (the "Original Issue Date")) and an aggregate offering price to
         the public of not less than $15,000,000 or (ii) at the election of the
         holders of a majority of the outstanding shares of Series A Preferred
         Stock. Notwithstanding the preceding sentence, upon the effectiveness
         of a firm commitment underwritten public offering covering the offer
         and sale of Common Stock for the account of the Corporation having an
         aggregate offering price to the public of not less than $12 million and
         closing on or prior to June 30, 1998, each share of Series A Preferred
         Stock shall be automatically converted into 1-2/3 shares of Common
         Stock. In the event of the occurrence of a public offering upon the
         terms and conditions set forth in either of the two preceding
         sentences, the person(s) entitled to receive the Common Stock issuable
         upon such conversion of Series A Preferred
<PAGE>
 
         Stock shall not be deemed to have converted such Series A Preferred
         Stock until immediately prior to the closing of such public offering."

         3. The foregoing amendment of the Articles has been duly approved by
the Board of Directors of the Corporation pursuant to Section 902 of the
California Corporations Code (the "Corporations Code").

         4. The foregoing amendment of the Articles has been duly approved by
the required vote of the shareholders of the Corporation pursuant to Sections
902 and 903 of the Corporations Code. The Corporation has two classes of shares,
Common Stock and Series A Preferred Stock (the "Preferred Stock"). Prior to the
approval of the foregoing amendment, the number of issued and outstanding shares
of Common Stock and Preferred Stock entitled to vote with respect to the
foregoing amendment were 7,532,301 and 900,000, respectively. The number of
shares of Common Stock voting in favor of the amendment exceeded the vote
required in that the affirmative vote of a majority of the outstanding shares of
Common Stock was required for approval of the amendment and the amendment was
approved by the affirmative vote of 90% of the outstanding shares of Common
Stock. The number of shares of Preferred Stock voting in favor of the amendment
exceeded the vote required in that the affirmative vote of a majority of the
outstanding shares of Preferred Stock was required for approval of the amendment
and the amendment was approved by the affirmative vote of 90% of the outstanding
shares of Preferred Stock.

April 1, 1998



ATG Inc.
47375 Fremont Boulevard
Fremont, California 94538

Ladies and Gentlemen:

We have acted as counsel for ATG Inc., a California corporation (the "Company"),
in connection with the preparation and filing of a registration statement on
Form S-1 (the "Registration Statement") with the Securities and Exchange
Commission (the "Commission") relating to the public offering by the Company of
1,700,000 shares of its Common Stock, no par value per share, plus an additional
255,000 shares of such Common Stock to cover over-allotments, if any
(collectively, the "Shares").

In connection with the opinions expressed herein, we have examined the following
documents: (i) the Registration Statement (including exhibits thereto); (ii) the
Articles of Incorporation of the Company, as amended; (iii) the Bylaws of the
Company, as amended; (iv) the minute books of the Company; (v) the form of
Underwriting Agreement (the "Underwriting Agreement") to be executed and
delivered by the Company and Van Kasper & Company (the "Underwriter"); (vi) the
form of Common Stock certificate of the Company; and (vii) such other documents
as we have deemed necessary or appropriate.

In our examinations, we have assumed the genuineness of all signatures, the
legal capacity of all natural persons, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified, photostatic or facsimile copies and the
authenticity of the originals of such documents.  For purposes of rendering the
opinion expressed herein, we have further expressly assumed that the
Registration Statement, as amended by Amendment No. 1 thereto filed with the
Commission on April 1, 1998, will be identical to the Registration Statement in
the form that is declared
<PAGE>
ATG Inc.

Page 2

 
effective by the Commission, and that the Underwriting Agreement as executed and
delivered by the Company and the Underwriter will be substantially the same as
the form of Underwriting Agreement attached as Exhibit 1.1 to the Registration
Statement, as amended by Amendment No. 1 thereto.

Based upon our examination of the foregoing documents, and expressly subject to
the assumptions set forth above, it is our opinion that, when issued and paid
for upon the effectiveness of the Registration Statement and in accordance with
the terms of the Underwriting Agreement and the final Prospectus contained in
the Registration Statement, the Shares will be validly issued, fully paid and
non-assessable.

We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to Graham & James LLP under the caption "Legal
Matters" in the Prospectus contained within the Registration Statement.

Very truly yours,



GRAHAM & JAMES LLP

1.0    GENERAL

1.1    Waste Management Federal Services of Hanford, Inc. (WMH) is the Waste
Management Projects subcontractor at the Department of Energy Richland
Operations Office (DOE-RL), Hanford Site, located in Richland, Washington. The
Hanford Site is managed by the Project Hanford Management Contractor (PHMC),
Fluor Daniel Hanford Inc. (FDH), which is directly contracted by DOE-RL. WMH is
acting on behalf of FDH as the Buyer for this procurement activity.

1.2    Prior to September 1991, the Hanford Site was tasked with a mission for
the production of special nuclear materials to support the Department of Defense
(DOD) weapons programs. Since that date, the Hanford Site has been tasked with a
mission to cleanup the Site. The new mission reinforces waste management
activities at the Hanford Site, and focuses on resolving legacy waste issues.
Waste management initiatives include, but are not limited to; waste
characterization, segregation, storage, processing, treatment, minimization and
permanent disposal.

1.3    A segment of the waste management task is to provide the means to safely,
effectively, expeditiously and economically treat for disposal, legacy mixed
waste (MW) currently being managed at the Hanford Site. MW results from the
combination of dangerous waste as designated by the Washington Administrative
Code, Dangerous Waste Regulations (WAC 173-303) with radioactive materials as
defined by the Atomic Energy Act (AEA, 1954). MW has been generated by Hanford
Site facilities and some approved Offsite facilities since 1987, and additional
MW is forecasted to be generated throughout Hanford's cleanup mission life-
cycle. Subject waste resides in Resource Conservation and Recovery Act (RCRA)
compliant storage at the Central Waste Complex (CWC) located in the 200 West
Area of the Hanford Site.

2.0    OBJECTIVES

2.1    The primary objective of this work activity is to acquire a commercial
treatment services vendor (referred to as the Contractor here forth) to perform
treatment on a specific volume of MW with similar treatment requirements (i.e.,
regulative and technology), thus rendering the waste acceptable for land
disposal at the Hanford Site. In all circumstances, the Contractor's waste
treatment capability(ies) shall be sufficiently robust to appropriately treat
the waste specified in Section 3.0.

                                                               SOW, PAGE 2 OF 12

3.0 WASTE SPECIFICATION

3.1    The waste to be treated under this SOW is designated as Contact Handled -
Low Level Mixed Waste (CH-LLMW) as determined by the Hanford Site Solid Waste
Acceptance Criteria (HSSWAC) (WHC, 1994). Approximately 125m/3/ of waste
constitutes the waste treatment lot (see Appendix-A for waste package listing).
The minimum contracted waste volume for treatment will be for 100m/3/ of drummed
and boxed waste.

3.2    The waste treatment lot contains greater waste volume than that specified
as the contracted volume. Upon mutual agreement between the Buyer and
Contractor, waste packages from the treatment lot will be selected for actual
treatment. Waste that has similar physical, chemical and radiological
characteristics to the waste specified in the waste treatment lot may be
substituted. This allows the Buyer and the Contractor some flexibility in what
waste will actually be treated, and it allows for waste substitution in the case
non-acceptable waste is encountered at the treatment facility.

3.3    To minimize impacts to the Buyers Onsite interfaces; (shipping/receiving
facilities, waste acceptance personnel.. etc.) and budget distributions; the
Contractor shall receive waste, ship treated waste, and invoice on a regular
basis to the greatest extent possible. The Buyer and Contractor shall mutually
agree on the shipping/receiving intervals and volume associated with each
shipment. In the case a mutual agreement cannot be obtained for Sections 3.2 and
3.3, the Buyer ultimately reserves the right to select the waste to be treated
and the shipping/receiving schedule.

3.4    The treatment Base Contract will be for a duration of two (2) years plus
one (1) additional year at the option of the Buyer. The Buyer requires that the
treatment Contractor complete waste treatment and ship all treated waste back to
the Buyer by the end of the specified contracting periods.

3.5    For this Contract, waste volumes to be treated will be based on the
internal volumes of the primary waste containers at the time waste
responsibility is transferred to the treatment Contractor. Volumes will be
specified on the applicable shipping papers.  Overpack containers used solely to
meet shipping requirements are not considered to be the primary container. See
the following examples for typical container waste volumes (not all inclusive):

            55-GAL DRUM:.............0.208 CUBIC METERS 
            85-GAL DRUM:.............0.322 CUBIC METERS 
            4'x4'x8' METAL BOX:......3.40  CUBIC METERS  
            B-25 BOX:................2.55  CUBIC METERS   

3.6    The Buyer will review and verify the characterization of each waste
package prior to releasing the waste to the Contractor. Waste characterization
needed to meet Department of Transportation (DOT), RCRA, and/or Washington State
Hazardous Waste Management Act (HWMA) regulations (as applicable) for waste
shipment will be performed by the Buyer.

                                                      P.O. MGK-SBB-A26602 ITEM-1
                                                               SOW, PAGE 3 OF 12

Any additional waste characterization to satisfy the Contractor's waste
acceptance criteria which are above and beyond DOT, RCRA, and/or HWMA
regulations for shipment, shall be the responsibility of the Contractor. The
waste's general physical, chemical and radiological characteristics are denoted
below.

   3.6.1  Waste is packaged per the HSSWAC. Packages are mostly 208-liter (55-
   gal) drums, some 322-liter (85-gal) drums, and various sized boxes up to
   1.83m(h) x 1.83m(w) x 3.05m(1) (6ft x 6ft x 10ft). Some of the waste will be
   overpacked due to primary waste container integrity issues or DOT regulation
   issues.

   3.6.2  The waste's physical characteristics are generally comprised of
   inorganic particulates, soils, sludges, and/or non-bulk liquids. The majority
   of the waste packages contain some debris type items (i.e., paper, plastic,
   metal.. etc.); however, all packages will contain greater than 50 volume
   percent non-debris material based on visual and/or real-time radiography
   inspection.

   3.6.3  The hazardous constituents in the waste are regulated by the HWMA
   (Chapter 70.105 Revised Code of Washington [RCW]), RCRA (42 USC 6901 et seq.)
   and the HWMA and RCRA implementing regulations contained in WAC (Chapter 
   173-303, Dangerous Waste Regulations) and Title 40 Code of Federal
   Regulations (CFR) respectively.

      3.6.3.1  The waste has been determined to either require stabilization
      treatment by means of a specified Technology-Based Standard, or
      stabilization is the Best Demonstrated Available Technology (BDAT)
      treatment for the waste. Other treatment technologies could be utilized
      provided the treatment is acceptable/approved by WDOE and/or EPA Region 10
      regulators. The Contractor may choose to treat the debris and non-debris
      components together or separately. If the Contractor chooses to treat them
      separately, then the Contractor assumes the added responsibility of
      meeting applicable treatment requirements specified in 40CFR268.45
      (treatment performance standards).

      3.6.3.2  The waste may contain any of numerous different waste
      constituents: characteristic waste constituents (D00l through D0ll),
      listed waste constituents (F001 through F005, "P"s and "U"s), and
      Washington State dangerous waste constituents (WT0l/2, WP01/2, WSC2, and
      W00l). See Appendix-A for container specific waste constituents.

      3.6.3.3  For waste that is designated with EPA hazardous waste numbers
      that require the identification of underlying hazardous constituents
      (UHC), the Buyer will specify the UHCs that are reasonably expected to be
      in the waste. Identification of the UHCs will be on the LDR treatment
      notification to be sent to the treatment Contractor at the time of waste
      shipment.

                                                      P.O. MGK-SBB-A26602 ITEM-1
                                                               SOW, PAGE 4 OF 12


   3.6.4  The radioactive constituents in the waste are governed by the AEA.
   Some or all of the radiological constituents tabulated in the HSSWAC (Table
   3-1) can be expected in the waste, including alpha emitting radionuclides.

      3.6.4.1  The activity concentration in individual waste packages will not
      exceed Category 3 or Class C limits as defined in the HSSWAC (WHC 1994).

      3.6.4.2  Transuranic radionuclides in the waste matrix will not exceed 100
      nCi/g (i.e., no "TRU" waste in the scope of this SOW) as defined in the
      HSSWAC (WHC 1994).

      3.6.4.3  All waste packages to be treated under the terms of this SOW will
      be Contact Handled (CH), meaning the dose rate on the container's outer
      surface will not exceed 200 mrem/hr. Waste packages will not be shielded
      to reduce the outer surface does rate; however, it is anticipated that
      some of the actual waste may exceed 200 mrem/hr limit after removing it
      from the packages. The Contractor shall have the provisions to handle
      waste that exceeds 200 mrem/hr. If waste in a container is suspected of
      exceeding 200 mrem/hr, the Buyer will flag the container (denote on
      traveler papers and container package) and notify the Contractor prior to
      the waste being signed over to the Contractor for treatment.

      container acceptance...etc.

      4.1.6.2  Treated waste from the Contractor shall be returned to the Buyer
      meeting the storage and disposal requirements of the Hanford Site. This
      acceptance is administered in the HSSWAC. Since the treated waste may
      reside in storage on the Hanford Site until the disposal site begins
      operation, the Contractor will be required to meet both the storage and
      disposal criteria. The only exception to this requirement is for waste
      that after treatment results in non-RCRA or Washington State regulated
      waste (i.e., treated characteristic only waste that can be disposed of

      in Hanford's low-level burial grounds); for this case, the waste can be
      packaged meeting the disposal requirements only. Treated waste packages
      shall be of size, shape and weight that can be readily/safely lifted and
      moved by means of conventional forklift type vehicles. The maximum package
      should not exceed 5ft x 5ft x 9ft in size and 16,000 pounds in weight. The
      Contractor can utilize other treated waste packages not meeting the above
      criteria if the Contractor provides the means to deliver and place the
      packages in the Buyer's disposal/storage unit.

      4.1.6.3  The Contractor shall have a documented methodology for meeting
      the applicable treatment requirements specified in this SOW. Included in
      with this methodology is acknowledgement from the WDOE and/or the EPA
      Region 10 that the Contractor's treatment approach meets the intended
      treatment and performance objectives. A Waste Certification Summary (WCS)
      shall be used to convey this treatment methodology (ref: HSSWAC, Section
      2.1.2). The WCS shall be submitted to the Buyer at least 60 days prior to
      treatment commencement.

      4.1.6.4  The Contractor shall notify the Buyer immediately if upon receipt
      inspection the Contractor discovers any significant discrepancies between
      quantity or type of dangerous waste designated on the manifest or shipping
      papers and the quantity or type of dangerous waste the Contractor actually
      receives. The Contractor and Buyer must attempt to reconcile the
      discrepancy within ten (10) calendar days after receiving the waste. If
      the discrepancy cannot be resolved within this period, the Contractor
      shall return the waste without delay back to the Hanford Site (the
      Contractor will be reimbursed actual transportation costs for the returned
      noncompliant waste.).

      4.1.6.5  Once the Contractor accepts the waste for treatment, the
      Contractor shall provide a final treated waste meeting the requirements of
      this SOW. Treated waste that analysis indicates do not conform with the
      requirements of this SOW will be controlled, documented, evaluated for the
      proper corrective action, and treated to conform at no additional cost to
      the Buyer.

   4.1.7  Laboratory Analysis

      4.1.7.1  The treated waste shall be characterized with sufficient accuracy
      to permit proper handling, storage, and disposal at the Buyer's site. This
      characterization shall ensure that, upon generation of the treated waste,
      the actual physical and chemical characteristics and major radionuclide
      content are recorded and known during all stages of the waste management
      process.

      4.1.7.2  The Contractor shall establish a "chain of custody" procedure for
      laboratory analysis samples in accordance with SW 846 methods. Sample
      analysis reports shall be clearly traceable back to specific waste
      shipments and manifests. Reports documenting laboratory analyses must be
      signed and certified by an authorized representative of the Contractor.
      All laboratory analysis work must be performed in compliance with 40 CFR
      260-271. 40 CFR 260-271 requires, in

Hanford Site is managed by the Project Hanford Management Contractor (PHMC),
Fluor Daniel Hanford Inc. (FDH), which is directly contracted by DOE-RL. WMH is
acting on behalf of FDH as the Buyer for this procurement activity.

1.2  Prior to September 1991, the Hanford Site was tasked with a mission for the
production of special nuclear materials to support the Department of Defense
(DOD) weapons programs. Since that date, the Hanford Site has been tasked with a
mission to cleanup the Site. The new mission reinforces waste management
activities at the Hanford Site, and focuses on resolving legacy waste issues.
Waste management initiatives include, but are not limited to; waste
characterization, segregation, storage, processing, treatment, minimization and
permanent disposal.

1.3  A segment of the waste management task is to provide the means to safely,
effectively, expeditiously and economically treat for disposal, legacy mixed
waste (MW) currently being managed at the Hanford Site. MW results from the
combination of dangerous waste as designated by the Washington Administrative
Code, Dangerous Waste Regulations (WAC 173-303) with radioactive materials as
defined by the Atomic Energy Act (AEA, 1954). MW has been generated by Hanford
Site facilities and some approved Offsite facilities since 1987, and additional
MW is forecasted to be generated throughout Hanford's cleanup mission life-
cycle. Subject waste resides in Resource Conservation and Recovery Act (RCRA)
compliant storage at the Central Waste Complex (CWC) located in the 200 West
Area of the Hanford Site.

2.0  OBJECTIVES

2.1  The primary objective of this work activity is to acquire a commercial
treatment services vendor (referred to as the Contractor here forth) to perform
treatment on a specific volume of MW with similar treatment requirements (i.e.,
regulative and technology), thus rendering

the waste acceptable for land disposal at the Hanford Site. In all
circumstances, the Contractor's waste treatment capability(ies) shall be
sufficiently robust to appropriately treat the waste specified in Section 3.0.

3.0  WASTE SPECIFICATION

3.1  The waste to be treated under this SOW is designated as Contact Handled -
Low Level Mixed Waste (CH-LLMW) as determined by the Hanford Site Solid Waste
Acceptance Criteria (HSSWAC) (WHC, 1994). Approximately, 2,300m/3/ of waste
constitutes the waste treatment lot. The waste treatment lot is divided into two
sub-lots; debris waste contained in drums (Appendix-A, approximately 500m/3/),
and debris waste contained in boxes (Appendix-B, approximately 1,800m/3/). The
Buyer has selected to awarded both sub-lots together.

3.2  The FY1999 Base Contract will be for a period of one (1) year with the
waste volumes to be treated as specified in Table-1. The Buyer may authorize
additional waste to be treated during FY2000 and FY2001 utilizing Contract
extension options. Contract extension options will be for a period of one (1)
year and will be for treatment of up to the maximum waste volumes specified in
Table-1. The Buyer requires that the treatment Contractor(s) be ready to accept
and treat waste by January 1, 1999; and all treated waste shall be shipped back
to the Buyer by September 30 of the specific contracting period. By mutual
agreement between the Buyer and the Contractor(s), treatment may begin earlier
then specified for the Base period or any option period.

3.3  The waste sub-lots contain greater waste volume than that specified as the
minimum contracted volumes. Upon mutual agreement between the Buyer and
Contractor(s), waste packages from the sub-lots will be selected for actual
treatment. Waste that has similar physical, chemical and radiological
characteristics to the waste specified in the sub-lots may be substituted. This
allows the Buyer and the Contractor(s) some flexibility in what waste will
actually be treated, and it allows for waste substitution in the case non-
acceptable waste is encountered at the treatment facility.

3.4  To minimize impacts to the Buyer's Onsite interfaces (shipping/receiving
facilities, waste acceptance personnel... etc.) and budget distributions; the
Contractor(s) shall receive waste, ship treated waste, and invoice on a regular
basis to the greatest extent possible. The Buyer and Contractor(s) shall
mutually agree on the shipping/receiving intervals and volume associated with
each shipment. In the case a mutual agreement cannot be obtained for Sections
3.3 and 3.4, the Buyer ultimately reserves the right to select the waste to be
treated and the shipping/receiving schedule.

3.5  For this Contract, waste volumes to be treated will be based on the
internal volumes of the primary waste containers at the time waste
responsibility is transferred to the treatment

Contractor. Volumes will be specified on the applicable shipping papers.
Overpack containers used solely to meet shipping requirements are not considered
to be the primary container. See the following examples for typical container
waste volumes (not all inclusive):

     55-GAL DRUM:.............   0.208 CUBIC METERS
     85-GAL DRUM:.............   0.322 CUBIC METERS
     4'x 4'x 8' METAL BOX:....   3.40  CUBIC METERS
     B-25 BOX:................   2.55  CUBIC METERS 

3.6  The Buyer will review and verify the characterization of each waste
package prior to releasing the waste to the Contractor. Waste characterization
needed to meet Department of Transportation (DOT), RCRA, and/or Washington State
Hazardous Waste Management Act (HWMA) regulations (as applicable) for waste
shipment will be performed by the Buyer. Any additional waste characterization
to satisfy the Contractor's waste acceptance criteria which are above and beyond
DOT, RCRA, and/or HWMA regulations for shipment, shall be the responsibility of
the Contractor. The waste's general physical, chemical and radiological
characteristics are denoted below.

   3.6.1  Waste is packaged per the HSSWAC. Drummed waste packages are mostly
   208-liter (55-gal) with some 322-liter (85-gal) packages. Boxes range up to
   1.83m(h) x 1.83m(w) x 3.05m(1) (6ft x 6ft x 10ft). Some of the waste will be
   overpacked due to primary waste container integrity issues or DOT regulation
   issues.

   3.6.2  The waste's physical characteristics are generally comprised of
   organic, inorganic and/or metallic debris type material meeting RCRA's debris
   definition depicted in 40 CFR268.2(g). Some of the waste packages contain
   some non-debris material (i.e., soil, particulate, sludge..etc.); however,
   all packages will contain greater than 50 volume percent debris material
   based on visual and/or real-time radiography inspection.

   3.6.3  The hazardous constituents in the waste are regulated by HWMA (Chapter
   70.105 Revised Code of Washington [RCW]), RCRA (42 USC 6901 et seq.) and the
   HWMA and RCRA implementing regulations contained in WAC (Chapter 173-303,
   Dangerous Waste Regulations) and Title 40 Code of Federal Regulations (CFR)
   respectively.

      3.6.3.1  The waste is most amenable to the alternative treatment standards
      for hazardous debris as specified in 40 CFR268.45; however, other
      applicable treatment standards specified in 40 CFR268.40 can be utilized.
      The Contractor may choose to treat the debris and non-debris components
      together or separately. If the Contractor chooses to treat them
      separately, then the Contractor assumes the added responsibility of
      meeting applicable treatment requirements specified in 40CFR268.40 (UHCs,
      sampling & analysis...etc.). The Buyer will not be providing waste
      characterization information for UHCs, the Contractor would need to assume
      all UHCs would apply.

                                                      P.O. MGK-SBB-A26602 ITEM-2
                                                               SOW, PAGE 5 OF 13

      3.6.3.2  The waste will contain many different waste constituents:
      characteristic waste constituents, listed waste constituents and
      Washington State dangerous waste constituents. See Appendix-A and B for
      container specific waste constituents.

      3.6.3.3  A significant percentage of the debris waste under this contract
      contains "organic/carbonaceous waste" as defined in WAC 173-303-140(3)(c).
      WMH is pursuing an exemption from the associated State-only
      organic/carbonaceous LDR (ref: WAC 173-303-140(4)(d)). WMH assumes that
      they will obtain subject exemption prior to treatment commencement, thus
      the treatment Contractor does not need to treat for this LDR.

   3.6.4  The radioactive constituents in the waste are governed by the AEA.
   Some or all of the radiological constituents tabulated in the HSSWAC (Table
   3-1) can be expected in the waste, including alpha emitting radionuclides.

      3.6.4.1  The activity concentration in individual waste packages will not
      exceed Category 3 or Class C limits as defined in the HSSWAC (WHC 1994).

      3.6.4.2  Transuranic radionuclides in the waste matrix will not exceed 100
      nCi/g (i.e., no "TRU" waste in the scope of this SOW) as defined in the
      HSSWAC (WHC 1994).

      3.6.4.3  All waste packages to be treated under the terms of this SOW will
      be Contact Handled (CH), meaning the dose rate on the container's outer
      surface will not exceed 200 mrem/hr. Waste packages will not be shielded
      to reduce the outer surface does rate; however, it is anticipated that
      some of the actual waste may exceed 200 mrem/hr limit after removing it
      from the packages. The Contractor shall have the provisions to handle
      waste that exceeds 200 mrem/hr. If waste in a container is suspected of
      exceeding 200 mrem/hr, the Buyer will flag the container (denote on
      traveler papers and container package) and notify the Contractor prior to
      the waste being signed over to the Contractor for treatment.

   a copy of all permits and licenses at least 60 days prior to commencing the
   first shipment of waste.

   4.1.3  TREATMENT TECHNOLOGY:

      4.1.3.1  The Contractor shall utilize treatment technologies meeting Best
      Demonstrated Available Technology (BDAT) applicable to RCRA Land Disposal
      Restrictions (LDR), WAC Dangerous Waste Regulations and the HSSWAC. The
      Buyer believes the most relevant BDAT treatment technology for treating
      subject waste is the immobilization technologies specified in 40
      CFR268.45. Other treatment technologies can be utilized provided such
      technologies satisfy treatment requirements set-forth in this SOW, and the
      technology is accepted by the Washington Department of Ecology (WDOE)
      and/or EPA Region 10 for disposing of at the Hanford Site.

      4.1.3.2   Waste treatment techniques such as sorting, shredding, cutting,
      and compaction shall be implemented as necessary to meet treatment
      requirements as stated in this SOW. No pre-treatment activities will be
      performed by the Buyer.

      4.1.3.3  The Contractor shall provide process flow diagrams and describe
      unit operations for each treatment unit employed to treat the waste
      described in Section 3.0.

   4.1.4  Waste Transportation:

      4.1.4.1  The Contractor shall provide and be responsible for all waste
      transportation from Hanford's waste shipping facilities to the
      Contractor's treatment unit, and returning treated waste back to the
      appropriate Hanford TSD facility.

      4.1.4.2  Transportation shall be in full compliance with DOT regulations
      in 49 CFR 171-180; Nuclear Regulatory Commission (NRC) regulations in 10
      CFR 71, and other applicable federal, state and local laws and
      regulations.

      4.1.4.3  The Buyer will manifest each waste shipment to the Contractor's
      treatment facility, and the Contractor shall manifest (as applicable) all
      treated waste shipments to the Buyer.

      4.1.4.4  Waste shipment responsibilities:

          (a)  On waste shipments originating from the Buyer's facilities, the
          Buyer is responsible for loading the Contractor's transportation
          vehicles. This includes providing the necessary loading equipment and
          personnel. The Contractor will be responsible for securing the load,
          adhering to all applicable requirements,
<PAGE>
 
                                                      P.O. MGK-SBB-A26602 ITEM-2
                                                               SOW, PAGE 7 OF 13

          and transporting the waste to their treatment facilities. Prior to
          leaving the Buyer's loading facilities; the Buyer's Transportation and
          Packaging Department will inspect the Contractor's loaded
          transportation vehicle to verify compliance with all applicable
          requirements, and radiation monitoring will be performed by the Buyer
          before vehicle release.

          (b) On shipments originating from the Contractor's facilities, the
          Contractor is responsible for loading their transportation vehicles.
          This includes providing the necessary loading equipment and personnel.
          The Contractor will be responsible for securing the load, adhering to
          all applicable transportation requirements, performing radiation
          monitoring, and transporting the treated waste to the Hanford Site.
          The Contractor's transportation vehicles shall be available for
          inspection by the Buyer's Transportation and Packaging Department to
          verify compliance with all applicable requirements prior to entering
          the Hanford Site. Inspections can take place at either the Buyer's
          inspection facility located in Richland, WA; or at the Contractor's
          loading facilities. The actual inspection location shall be defined in
          the Contractor's Transportation Plan. Radiation monitoring will be
          performed on the Contractor's vehicles by the Buyer at his discretion
          during the above noted inspection. The Buyer requires a minimum 24-
          hour notice to schedule Transportation and Packaging personnel to
          inspect the Contractor's vehicles.

      4.1.4.5  Hanford's TSD facilities are operated primarily on dayshift
      (7:30am - 4:00pm) during weekdays (M-F). The Contractor may make
      arrangements with the Buyer to pick-up or drop-off waste shipments at
      other times provided the Contractor provides a minimum 48-hour notice to
      the Buyer.

   4.1.5  Radionuclide Inventory:

      4.1.5.1  The Contractor shall maintain the integrity of the Hanford Site's
      radionuclide inventory during all phases of waste shipment, storage,
      treatment, analysis, and treated waste return. At a minimum, the
      Contractor shall segregate subject waste from other clients waste,
      decontaminate treatment equipment prior to and after treating subject
      waste, and return or incorporation all secondary waste (including system
      HEPA filters) generated from the treatment of subject waste.

      4.1.5.2  Since the waste inventory contains radioactive elements including
      transuranic constituents, if treatment could result in a concentration of
      radioactive elements, the Contractor shall administratively control the
      waste feed so that no TRU Greater Than Category 3, or Greater Than Class
                         --
      C waste (as defined in the HSSWAC) is generated.

                                                               SOW, PAGE 8 OF 13

   4.1.6  Waste Acceptance Criteria:

      4.1.6.1  The Contractor shall have a waste acceptance criteria established
      to cover all the waste specified in Section 3.0. The waste acceptance
      criteria shall address all pertinent waste attributes including:
      radioisotope quantities/concentrations, criticality safety limits,
      external radiation and heat generation, restrictions on types of waste,
      container acceptance etc.

      4.1.6.2  Treated waste from the Contractor shall be returned to the Buyer
      meeting the storage and disposal requirements of the Hanford Site. This
                  --------------------
      acceptance is administered in the HSSWAC. Since the treated waste may
      reside in storage on the Hanford Site until the disposal site begins
      operation, the Contractor will be required to meet both the storage and
      disposal criteria. The only exception to this requirement is for waste
      that after treatment results in non-RCRA or Washington State regulated
      waste (i.e., treated characteristic only waste that can be disposed of in
      Hanford's low-level burial grounds); for this case, the waste can be
      packaged meeting the disposal requirements only. Treated waste packages
      shall be of size, shape and weight that can be readily/safely lifted and
      moved by means of conventional forklift type vehicles. The maximum package
      should not exceed 5ft x 5ft x 9ft in size and 16,000 pounds in weight. The
      Contractor can utilize other treated waste packages not meeting the above
      criteria if the Contractor provides the means to deliver and place the
      packages in the Buyer's disposal/storage unit.

      4.1.6.3  The Contractor shall notify the Buyer immediately if upon receipt
      inspection the Contractor discovers any significant discrepancies between
      quantity or type of dangerous waste designated on the manifest or shipping
      papers and the quantity or type of dangerous waste the Contractor actually
      receives. The Contractor and Buyer must attempt to reconcile the
      discrepancy within ten (10) calendar days after receiving the waste. If
      the discrepancy cannot be resolved within this period, the Contractor
      shall return the waste without delay back to the Hanford Site (the
      Contractor will be reimbursed actual transportation costs for the returned
      noncompliant waste.).

      4.1.6.4  Once the Contractor accepts the waste for treatment, the
      Contractor shall provide a final treated waste meeting the requirements of
      this SOW. Treated waste that does not conform with the requirements of
      this SOW will be controlled, documented, evaluated for the proper
      corrective action, and treated to conform at no additional cost to the
      Buyer.

    4.1.7  Treated Waste Requirements

      4.1.7.1  The treated waste shall be characterized with sufficient accuracy
      to permit proper handling, storage, and disposal at the Buyer's site. This
      characterization shall ensure that, upon generation of the treated waste,
      the actual physical and chemical characteristics and major radionuclide
      content are recorded and known during all stages of the waste management
      process.

                                                               SOW, PAGE 9 of 13

      4.1.7.2  The Contractor shall have a documented methodology for meeting
      the applicable treatment requirements specified in this SOW. Included in
      with this methodology is acknowledgement from the WDOE and/or the EPA
      Region 10 that the Contractor's treatment approach meets the intended
      treatment and performance objectives. A Waste Certification Summary (WCS)
      shall be used to convey this treatment methodology (ref: HSSWAC, Section
      2.1.2). The WCS shall be submitted to the Buyer at least 60 days prior to
      treatment commencement.

      4.1.7.3  If sampling is utilized for verifying the treated waste form
      (i.e., 40 CFR268.40 treatment in lieu of 40 CFR268.45), the Contractor
      shall specify the sampling methodology and frequency utilized in
      certifying the waste meets disposal criteria. The sampling criteria shall
      be based on statistical analysis techniques and confidence levels
      documented in the Contractor's Waste Analysis Plan (WAP). At a minimum,
      the Contractor shall plan on sampling 10 percent of the outgoing treated
      waste packages.

      4.1.7.4  As applicable, the Contractor shall establish a "chain of
      custody" procedure for laboratory analysis samples in accordance with SW
      846 methods. Sample analysis reports shall be clearly traceable back to
      specific waste shipments and manifests. Reports documenting laboratory
      analyses must be signed and certified by an authorized representative of
      the Contractor. All laboratory analysis work must be performed in
      compliance with 40 CFR 260-271. 40 CFR 260-271 requires, in some cases,
      compliance with test methods defined in EPA SW 846, Test Methods for the
                                                          --------------------
      Evaluation of Solid Waste, Physical/Chemical Methods, most recent edition,
      ----------------------------------------------------
      (SW 846). The Contractor shall conduct laboratory analysis on the treated
      waste sufficient to certify the treated waste meets WDOE, federal
      regulations, and the HSSWAC requirements. The laboratory(ies) utilized for
      treated waste testing shall be approved by the Buyer prior to initiating
      waste treatment.

      4.1.7.5  The Contractor shall provide additional samples (i.e., split
      samples) of the treated waste to the Buyer, on a per-request basis, to
      verify that the treated waste meets the requirements of this SOW. The
      Buyer reserves the right to be present during all sampling and analysis
      activities.

      4.1.7.6  The Contractor's subcontracted laboratories performing analysis
      on the Buyer's waste shall return excess waste sample material and/or
      sample residues back to the Contractor. The Contractor in turn shall treat
      the excess sample material and/or sample residues in accordance with the
      requirements of this SOW, and return treated material to the Buyer.

   4.1.8  Safety

      4.1.8.1  The Contractor shall have developed, implemented, and maintained
      a written Health and Safety Program which complies with 29 CFR Part

          (2)  Weight of the waste (total of waste and any solidification or
               absorbent media);
          (3)  Volume of the waste (total of waste and any solidification or
               absorbent media);
          (4)  Other data necessary to demonstrate compliance with waste
               acceptance criteria;
          (5)  Major radionuclides and their concentrations;
          (6)  Packaging date, package weight, and external volume;
          (7)  All analytical and test data needed to verify treated waste
               performance for certification and disposal.

      (b) Waste manifest records shall be maintained by the Contractor for waste
      received by the Contractor, and the Contractor shall manifest the treated
      waste back to the Buyer. The manifest shall contain data necessary to
      document the proper classification, and verify proper treatment, storage,
      and disposal of the waste. Waste manifests shall be kept as permanent
      records by the Contractor.

      (c) The Contractor shall maintain the following records related to proper
      plant and equipment operation:

          (1)  All process data needed to verify equipment operation within
               specific parameters during production in order to certify that
               the treated waste (entire container contents) meets established
               acceptance/performance criteria;
          (2)  Process analytical and test data to verify that the entire
               container contents meet established waste acceptance criteria;
          (3)  Data pertinent to tracking container contents entering the
               treatment facility to the exiting treated waste containers for
               waste category verification purposes as required by regulations.

               NOTE:  The concentration of a radionuclide may be determined by
               direct methods or by indirect methods such as use of scaling
               factors which relate the inferred concentration of one
               radionuclide to another that is measured, or radionuclide
               material accountability, if there is reasonable assurance that
               the indirect methods can be correlated with actual measurements.

   4.1.11  Documentation

      4.1.11.1  Final Treated Waste Certification: Each batch or lot of treated
      waste shall be certified by the Contractor for meeting the requirements
      set-forth in this SOW. A treated waste certification portfolio shall be

      the control, evaluation, and corrective action for treated waste that is
      found to not meet the requirements of this SOW after initial treatment. A
      non-conformance report is required to be generated by the Contractor
      within fifteen (15) working days for each container, lot or batch that is
      determined to not comply with those requirements. Methods to disposition
      the non-conforming material and prevention of repeated incidents of non-
      conformance will be detailed, in this report. A copy of the non-
      conformance reports, and the results of the follow-up actions, will be
      transmitted to the Buyer within five (5) working days of the completion of
      the report. Concurrence with non-conforming material disposition by the
      Buyer is required prior to shipment of the treated waste to the Buyer.

                    or not there has been an extraordinary nuclear occurrence
                    will be made in accordance with the procedures in 10 Code of
                    Federal Regulation (CFR) 123 part 840.

               F.   For the purposes of that determination, "Offsite" as that
                    term is used in 10 CFR 123 part 840 means away from "the
                    contract location" which phrase means any DOE facility,
                    installation, or site at which contractual activity under
                    this contract is being carried on, and any subcontractor-
                    owned or controlled facility, installation, or site at which
                    the subcontractor is engaged in the performance of
                    contractual activity under this contract.

     3.   The waivers set forth above:

          A.   Shall be effective regardless of whether such issue or defense
               may otherwise be deemed jurisdictional or relating to an element
               in the cause of action;

          B.   Shall be judicially enforceable in accordance with its terms by
               the claimant against the person indemnified;

          C.   Shall not preclude a defense based upon a failure to take
               reasonable steps to mitigate damages;

          D.   Shall not apply to injury or damage to a claimant or to a
               claimant's property which is intentionally sustained by the
               claimant or which results from a nuclear incident intentionally
               and wrongfully caused by the claimant;

          E.   Shall not apply to injury to a claimant who is employed at the
               site of and in connection with the activity where the
               extraordinary nuclear occurrence takes place, if benefits
               therefor are either payable or required to be provided under any
               workmen's compensation or occupational disease law;

          D.   Shall not apply to any claim resulting from a nuclear incident
               occurring outside the United States;

               forth in this clause and in insurance policies, contracts, or
               other proof of financial protection; and

          F.   Shall not apply to, or prejudice the prosection or defense of,
               any claim or portion of claim which is not within the protection
               afforded under (1) the limit of liability provisions under
               subsection 170E. Of the Act, and (2) the
<PAGE>
 
                                                                               9

               terms of this agreement and the terms of insurance policies,

     F.   Notification and Litigation of Claims.

          The subcontractor shall give immediate written notice to WHC and the
          DOE contracting officer of any known action or claim filed or made
          against the subcontractor or other person indemnified for public
          liability as defined in paragraph D.2. Except as otherwise directed by

          indemnified in any action brought upon any claim that the DOE may be
          required to indemnify hereunder; take charge of such action, and
          settle or defend any such action. If the settlement or defense of any
          such action or claim is undertaken by DOE, the subcontractor or other
          person indemnified shall furnish all reasonable assistance in
          effecting a settlement or asserting a defense.

     G.   Continuity of U.S. Department of Energy Obligations.

          The obligations of the DOE under this clause shall not be affected by
          any failure on the part of the subcontractor to fulfill its obligation
          under this contract and shall be unaffected by the death, disability,
          or termination of existence of the subcontractor, or by the
          completion, termination, or expiration of this contract.

     H.   Effect of Other Clauses.

          The provisions of this clause shall not be limited in any way by, and
          shall be interpreted without reference to, any other clause of the
          contract, including the clause entitled Contract Disputes, provided,
          however, that this clause shall be subject to the clauses entitled
          Covenant Against Contingent Fees, Officials not to Benefit, and
          Examination of Records by the Comptroller General, and any provisions
          that are later added to this contract as required by applicable
          Federal law, including statutes, executive orders, and regulations, to
          be included in nuclear hazards indemnity agreements.

     I.   Civil Penalties.

          The subcontractor and its subcontractors and suppliers who are
          indemnified under the provisions of this clause are subject to civil
          penalties, pursuant to 234A of the Act, for violations of applicable
          DOE Nuclear-Safety related rules, regulations, or orders.
<PAGE>
 
                                                                              10

     J.   Criminal Penalties.

          Any individual director, officer, or employee of the subcontractor or
          of its subcontractors and suppliers who are indemnified under the
          provisions of this clause are subject to criminal penalties, pursuant
          to 223(C) of the Act, for knowing and willful violation of the Atomic
          Energy Act of 1954, as amended, and applicable DOE nuclear safety-
          related rules, regulations or, orders which violation results in, or,
          if undetected, would have resulted in a Nuclear Incident.

     K.   Inclusion in Subcontracts.

          The subcontractor shall insert this clause in any subcontract which
          may involve the risk of public liability, as that term is defined in
          the Act and further described in paragraph D.2 above. However, this
          clause shall not be included in subcontracts in which the
          subcontractor is subject to Nuclear Regulatory Commission (NRC)
          financial protection requirements under section 170B. of The Act or
          NRC agreements of indemnification under section 170C. or K. of the Act
          for the activities under the subcontract.

     L.   Indemnification of Westinghouse Hanford Company

          To the extent permitted by law, the subcontractor assumes full
          responsibility and shall indemnify, save harmless, and defend WHC; its
          principal subcontractors, ICF Kaiser Hanford Company and Boeing
          Computer Services Richland, Inc.; Their agents; officers; employees;
          and directors from any civil or criminal liability under sections 234A
          or 223(C) of the Act or the implementing regulations at 10 CFR 223
          820, et seq., arising out of the activities of the subcontractor, its
          lower-tier subcontractors, suppliers, agents, employees, officers, or
          directors. The subcontractor's obligation to indemnify and hold
          harmless shall expressly include attorneys fees and other reasonable
          costs of defending any action or proceeding instituted under sections
          234A or 223(C) of the Act or the implementing regulations at 10 CFR
          123 820, et seq.

          A copy of the implementing regulations at 10 CFR 123 820, et seq.,
          Will be made available to the subcontractor upon request.

LIMITATIONS OF FUNDS (H29X)

1.   Although the parties hereto have negotiated the ceiling price of
     $15,985,915 for this Purchase Order (hereafter referred to as the Order),
     not including the five annual option periods, they understand that
     sufficient funds for the full scope of work are not yet available and that
     presently there is obligated only the sum of $1,015,207, which equates to
     the maximum termination cost for Year 1 per the Termination Liability
     Schedule (Attachment 5) based on a 5 year permitting/licensing project
     duration. It is anticipated that from time to time additional funds will be
     obligated to this order by Westinghouse Hanford Company (WHC).

2.   Seller agrees to perform, or have performed, work up to the point at which,
     in the event of termination of this Order pursuant to the clause entitled
     "Termination", the total amount payable by WHC, including amounts payable
     with respect to subcontracts and settlement costs, and pursuant to
     paragraph 5 hereof, (hereafter called the "Termination Amount", would in
     the exercise of reasonable judgment by the Seller approximate the total
     amount then obligated to the Order. WHC shall not be obligated in any event
     to pay or reimburse the Seller in excess of the amount then currently
     obligated to the Order notwithstanding any other provision of this Order.

3.   It is contemplated that funds presently obligated to this Order will cover
     the work to be performed during the first year following award.  In the
     event Seller considers the funds obligated Seller to be inadequate to cover
     the work to be performed until such time, or an agreed date in substitution
     thereof, the Seller shall notify WHC in writing when within
<PAGE>
 
                                                                              12

     the next thirty (30) days, the work will reach a point at which the
     termination amount approximates 85 percent of the total amount then
     obligated to the Order. The notice shall state the estimated date when such
     termination amount will be reached and the estimated amount of additional
     funds required to continue performance to the above or an agreed
     substituted date. If after such notification, additional funds are not
     obligated by such date or by an agreed date in substitution thereof, WHC
     shall upon Seller's written request, terminate this Order on such date or
     the date set forth in the request, whichever is later, pursuant to the
     provisions of the "Termination" clause of this Order.

4.   When additional funds are obligated from time to time for continued
     performance of the work under this Order, the parties shall agree on the
     applicable period of Order performance which shall be covered by such
     funds. The provisions of paragraphs 2 and 3 above shall apply to such
     additional obligated funds and substituted date and the Order amended
     accordingly.

5.   If the Seller incurs additional cost, or is delayed in the performance of
     the work under this Order, solely by reason of the failure of WHC to
     obligate additional funds in amounts sufficient for the timely performance
     of this Order, and if additional funds are obligated, an equitable
     adjustment shall be made in the price or prices, (including appropriate
     target, billing, and ceiling prices where applicable), of said item or in
     the time of delivery, or both.

6.   WHC may at any time prior to termination, obligate additional funds for
     this Order.

7.   Modification of this Order under the "Changes" article shall not constitute
     a change in the amount obligated under this clause.

8.   Nothing in this clause shall affect the right of WHC to terminate this
     Order pursuant to the termination provisions of the Order.

<PAGE>
 
                                                                              14

Environment, Safety and Health (Government Owned or Leased)

     (a)  It is understood that it is the goal of both the Contractor and DOE to
          conduct a responsible and comprehensive program to assure that the
          Hanford Site is an environmentally acceptable installation and 
<PAGE>
 
                                                                              15

          is operated in a safe and healthy manner. It is DOE policy to use its
          best efforts to provide the funds or other resources necessary to
          achieve this purpose and to continue cooperating, along with the
          Contractor, with Federal and State agencies having interest in
          environmental matters to accomplish this purpose, and to maintain good
          relations with such agencies.

     (b)  Performance of work under this contract shall be conducted in a manner
          that is protective of the environment and the health and safety of
          employees and the public. The Contractor shall comply with all
          applicable environmental, safety, and health requirements (including
          applicable permitting and reporting requirements) including federal,
          state, and local laws and regulations and DOE requirements.

          (1)  The Contracting Officer shall notify the Contractor, in writing,
               of any noncompliance with applicable requirements. After receipt
               of such notice, the Contractor shall immediately take corrective
               action, consistent with the clause of this contract entitled
               "Work Control System/Technical Direction" and availability of
               funds. In the event that the Contractor fails to take corrective
               action, the Contracting Officer may for cause, without prejudice
               to any other legal or contractual rights of DOE, issue an order
               stopping all or any part of the work; thereafter, a start order
               for resumption of the work may be issued at the discretion of the
               Contracting Officer. The Contractor shall not be entitled to an
               extension of time or additional fee or damages by reason of, or
               in connection with, any work stoppage that was appropriately
               ordered in accordance with this clause.

          (2)  If at any time during performance of the contract work, the
               Contractor's act or failure to act causes substantial harm or an
               imminent danger to the health or safety of individuals or the
               environment, the Contracting Officer may, without prejudice to
               any other legal or contractual rights of DOE, issue an order
               stopping all or any part of the work; thereafter, a start order
               for resumption of the work may be issued at the discretion of the
               Contracting Officer.  The Contractor shall not be entitled to an
               extension of time or additional fee or damages by reason of, or
               in connection with, any work stoppage that was appropriately
               ordered in accordance with this clause.

     (c)  The Contractor shall submit, within 30 days after the date of award of
          this contract modification, an environmental, safety, and health
          program management and implementation plan to the Contracting Officer
          for review and approval.  The plan shall describe the management
          systems to be employed to ensure that environmental, safety and health
          requirements are appropriately considered in all phases of contract
          activities.  The plan shall also include provisions for an internal
          environmental, safety and health 
<PAGE>
 
                                                                              16

          performance evaluation and corrective action system to provide
          management with a continuing assessment of the adequacy and
          implementation of the environmental, safety and health programs and
          assurance that deficiencies are corrected. The results of such
          evaluations shall be made available to DOE.

     (d)  The Contractor shall include in all of its subcontracts, involving
          performance of work at the site, the provisions requiring
          subcontractors to comply with the Contractor's environmental, safety
          and health requirements.  However, such provisions in the subcontracts
          shall not relieve the Contractor of its obligations to assure
          compliance with the provisions of this clause for all aspects of the

1.0  INTRODUCTION
     ------------

Westinghouse Hanford Company is authorized on behalf of the U.S. Department of
Energy, Richland Operations Office (RL) to provide waste management services for
the Hanford Site.

Low-Level Mixed Waste (LLMW) that is thermally treatable is generated by Hanford
Site waste generating facilities and other facilities that ship waste to the
Hanford Site. This procurement is seeking an organization(s) (referred to as
"the Seller" in this document) to transport and thermally treat Hanford Site
LLMW.


2.0  SERVICES - GENERAL
     ------------------

Seller shall provide a service for the thermal treatment of LLMW and return the
ash/residue accompanied by the results of laboratory analysis. The Seller shall
provide the transportation for the waste to and from the Hanford Site. The
thermal treatment service shall be in accordance with all applicable local,
state, and federal laws and regulations, and Hanford Site requirements as stated
in this Statement of Work (SOW).


3.0  WASTE
     -----

The waste is classified by Hanford Site Solid Waste Acceptance Criteria (HSSWAC)
(WHC 1993) as LLMW and is containerized in drums and boxes and may require size
reduction prior to thermal treatment. Size reduction would be performed by the
Seller, if required.

The waste to be treated contains less than 100 nCi/gm of transuranic (TRU)
radioactive elements. Container surface radiation dose rate is less than 100
mrem/hr. Detailed information describing the existing subject waste inventory is
provided in the document titled: Characterization of Waste LLMW Inventory. This
information is derived from process knowledge or analysis of the waste.
Documents describing regulatory requirements are given in the reference list.

*    includes current inventory

Hanford site waste generators are required to characterize radioactive mixed
waste (RMW) for storage in the Central Waste Complex. The Buyer shall review
this characterization of each container prior to shipment of waste to sellers
facility. Any additional characterization required to meet Department of
Transportation, Resource Conservation and Recovery Act (RCRA), Toxic Substances
Control Act (TSCA), and Washington State Hazardous Waste Management Act (WSHWMA)
regulations for shipment will be performed by Westinghouse Hanford Company.

It is possible that some waste may require additional characterization before it
can be accepted or treated by the Seller. Any additional characterization of the
waste to satisfy waste acceptance criteria which are above and beyond DOT, RCRA,
TSCA and WSHWMA regulations for shipment, shall be performed by the Seller.

4.0  TREATMENT
     ---------

The radioactive constituents in the waste are regulated by those portions of DOE
Order 5820.2A, Radioactive Waste Management, (DOE 1988) that pertain to the
management of low-level waste and include the requirements in Attachment

A. The radioactive constituents in the waste are also regulated by the Hanford
Site-specific performance assessment criteria discussed in Section 5.0 of this
SOW. The hazardous components in the waste are regulated by the Washington State
Hazardous Waste Management Act (WSHWNA) (Chapter 70.105 Revised Code of
Washington [RCW]), Resource Conservation and Recovery Act (RCRA) (42 USC 6901 et
seq.) and the Toxic Substances Control Act (TSCA) (15 U.S.C. 2601 et seq.) and
the WSHWMA, RCRA and TSCA implementing regulations contained in Chapter 173-303
Washington Administrative Code (WAC) Dangerous Waste Regulations and Title 40
Code of Federal Regulations (CFR) respectively.

                                       2
<PAGE>
 
The treatment criteria specified in WAC 173-303-140 "Land Disposal
Restrictions", Title 40 CFR Part 268, "Land Disposal Restrictions" and Title 40
CFR, Part 761.70, "Incineration of PCBs and PCB Items" must be achieved.

The Seller will be required to maintain the integrity of the radionuclide
inventory during all phases waste shipment, waste treatment, and ash return.
This may require that the Seller treat the waste in dedicated campaigns. The
laboratory analyses required on the waste and the ash/residue shall provide
evidence that the integrity of the radionuclide inventory has been maintained.
The Buyer may inspect at any time any portion of the Seller's and the Seller's
subcontractor's facilities which may come in contact with the waste to be
treated.

The Seller shall be responsible for all permits and licenses for the
transportation and waste treatment of this waste. The Buyer will be provided, a
copy of all permits and licenses sixty (60) days prior to commencing the first
shipment of waste.

5.0  ASH/RESIDUE AND WASTE CONTAINERS
     --------------------------------

The treatment process shall generate a stabilized, solid ash/residue final waste
form. All ash/residue resulting from thermal treatment of the waste shall be
packaged and returned to the Hanford Site for disposal in accordance with HSSWAC
(WHC 1993) and Department of Transportation Regulations (49 CFR 171-179). Unless
prohibited by the characteristics of the ash/residue, fifty-five (55) gallon
drums will be used to return the ash/residue. The HSSWAC (WHC. 1993) contains
information on transportation and container requirements as well as the Hanford
Site process for accepting waste for disposal.

The waste inventory contains radioactive elements including transuranic
constituents. The concentration effect associated with volume reduction by
thermal treatment can increase the concentration of radioactive constituents in
the final waste form. The Offeror shall administratively control the waste feed
so that no TRU waste (as defined by the HSSWAC (WHC 1993)) and no Greater Than
Class C waste (in accordance with 10 CFR 61.55) is generated.

The Seller shall certify that the treated ash/residue, waste container, surface
contamination, and surface dose rates satisfy all applicable requirements for
disposal at the Buyer's LLMW disposal facility. For applicable waste codes, the
Seller shall certify treatment to Land Disposal Restriction standards.
Applicable requirements include the following: the land disposal restriction
standards as specified in Chapter 40, Code of Federal Regulations, Part 268;
Chapter 40 CFR 264 and 265, Subpart "N" "Landfills"; Washington State
Administrative Code (WAC) "Dangerous Waste Regulations" (WAC 173-303); and the
HSSWAC (WHC 1993).

In addition to the requirements specified in the above regulations, the returned
ash/residue must meet the following Hanford Site-specific performance assessment
criteria:

                                       3
<PAGE>
 
1.   The ash/residue final waste form shall be a stabilized solid, or the
     treatment process shall produce a stabilized, solid waste form such as a
     glass or a slag. The stabilized, solid waste form shall exhibit a
     compressive strength greater than 50 psi.

2.   The stabilized, solid waste form shall be packaged in containers having
     a void volume percentage of less than 10 percent.

3.   If the ash/residue contains any of the five radionuclides, Tc99, Se79,
     I129, C14, or uranium and has a total activity concentration for these
     radionuclides greater than or equal to 0.0001 Ci/m/3/ and less than or
     equal to 0.001 Ci/m3/3/ the stabilized waste form shall exhibit a diffusion
     coefficient less than or equal to 10-10 cm/2//sec (Leachability Index
     greater than or equal to 10.0) when subjected to leach testing in
     accordance with American Nuclear Society Procedure 16.1 (ANSI 1986).

4.   If the ash/residue contains any of the five radionuclides, Tc/99/, Se/79/,
     I/129/, C/14/, or uranium and has a total activity concentration for these
     radionuclides greater than or equal to 0.0001 Ci/m/3/ and less than or
     equal to 0.001 Ci/m/33/ the stabilized waste form shall exhibit a diffusion
     coefficient less than or equal to 10/-12/ cm/2//sec (Leachability Index
     greater than or equal to 12.0) when subjected to leach testing in
     accordance with American Nuclear Society Procedure 16.1 (ANSI 1986).

5.   If the ash/residue contains uranium in activity concentrations greater than
     0.01 Ci/m/3/ the ash/residue must be encapsulated in a Portland cement-
     based grout matrix. Any treatment process that produces a glass or a slag
     final waste form will require administrative controls of the feed
     composition on an individual container basis to avoid this requirement.
     Analysis of the waste inventory suggests that only a few containers will
     require such administrative controls.


Seller shall provide analytical characterization data on the ash/residue
sufficient to meet the requirements of all state and federal regulations, the
HSSWAC (WHC 1993), and the above Hanford Site-specific performance assessment
criteria. Each ash/residue container shall be assigned a Hanford Site-specific
package identification number (PIN). This PIN shall be referenced on all data,
documentation, and correspondence relating to the waste container. The container
itself shall be physically identified with that number in accordance with the
specifications described in the HSSWAC (WHC 1993).

6.0  LABORATORY ANALYSIS AND QUALITY ASSURANCE
     -----------------------------------------

All records associated with the Buyer's wastes (including but not limited to
Seller's sample analysis results) shall be maintained by the Seller using a

                         MANAGEMENT OF LOW-LEVEL WASTE

WASTE CHARACTERIZATION.

(1)  Low-level waste shall be characterized with sufficient accuracy to permit
     proper segregation, treatment storage, and disposal. This characterization
     shall ensure that, upon generation and after processing, the actual
     physical and chemical characteristics and major radionuclide content are
     recorded and known during all stages of the waste management process.

(2)  Waste characterization data shall be recorded on a waste manifest and shall
     include:


          (a)  The physical and chemical characteristics of the waste.


          (b)  Volume of the waste (total of waste and any solidification
               or absorbent media).
          
          (c)  Weight of the waste (total of waste and any solidification
               or absorbent media).
          
          
          (d)  Major radionuclides and their concentrations.
          
          (e)  Packaging date, package weight, and external volume.

(3)  The concentration of a radionuclide may be determined by direct methods or
     by indirect methods such as use of scaling factors which relate the
     inferred concentration of one radionuclide to another that is measured, or
     radionuclide material accountability, if there is reasonable assurance that
     the indirect methods can be correlated with actual measurements.

WASTE ACCEPTANCE CRITERIA.

(1)  Waste acceptance criteria shall be established for each waste treatment,
     storage, and disposal facility, and submitted.

(2)  The waste acceptance criteria for treatment, storage, or disposal
     facilities shall address the following issues:


          (a)  Allowable quantities/concentrations of specific
               radioisotopes to be handled, processed, stored or disposed
               of;
          
          (b)  Criticality safety requirements (waste forms and
               geometries);

                                      10
<PAGE>
 
          (c)  Restrictions regarding low-level waste classified for
                security reasons;
          
          (d)  External radiation and internal heat generation;
          
          (e)  Restrictions on the generation of harmful gases, vapors, or
                liquids in waste;
          
          (f)  Chemical and structural stability of waste packages,
                radiation effects, microbial activity, chemical reactions, and
                moisture;

          (g)  Restrictions for chelating and complexing agents having the
                potential for mobilizing radionuclides; and

          (h)  Quantity of free liquids.

WASTE TREATMENT.

(1)  Waste shall be treated by appropriate methods so that the disposal site can
     meet performance objectives.

(2)  Waste treatment techniques such as incineration, shredding, and compaction
     to reduce volume and provide more stable waste forms shall be implemented
     as necessary to meet performance requirements. Use of waste treatment
     techniques to increase the life of the disposal facility and improve long-
     term facility performance, by improved site stability and reduction of
     infiltrating water, is required to the extent it is cost effective.

(3)  The development of large scale waste treatment facilities shall be
     supported by the appropriate National Environmental Policy Act.

(4)  Operation of waste treatment facilities shall be supported by adequate
     documentation including the following:

     stored, and shipped at the facilities under its cognizance. The data
     maintained shall include all data necessary to show that the waste was
     properly classified, treated, stored, and shipped. The data maintained in
     the system shall be based on the data recorded on waste manifests.

(2)  Waste Manifest. Records shall be kept and accompany each waste package from
     generator through final disposal. The manifest shall contain data necessary
     to document the proper classification, and assist in determining proper
     treatment, storage, and disposal of the waste. Waste manifests will be kept
     as permanent records. At a minimum, the following data will be included:

          (a)  Waste physical and chemical characteristics,

          (b)  Quantity of each major radionuclide present;

                                                           Revision 2 (10/20/95)

                          MEMORANDUM OF UNDERSTANDING
               Low Level Mixed Waste Thermal Treatment Services
                       WHC Purchase Order MW6-SBV-357079

This Memorandum of Understanding provides clarification to key points that are
crucial to the order. This document does not replace the Statement of Work.

1.   ATG will treat all waste categories for which thermal treatment and/or
     gasification/immobilization is specified as applicable treatment.

2.   ATG proposes to vitrify all wastes except some of the secondary waste from
     the air pollution control system and waste that can be classified as
     debris.

3.   ATG agrees to meet the void space requirement in the SOW and the Hanford
     Site Solid Waste Acceptance Criteria.

4.   ATG shall provide analytical capabilities (Hazardous and Radiological) to
     adequately verify all incoming waste streams, monitor in process, and
     characterize product waste streams that meet all regulatory and WHC
     requirements referenced in the SOW.

5.   ATG's sampling and analysis plan will be provided to WHC when ATG's RCRA
     Permit is submitted to the State of Washington for approval.

6.   The ATG onsite laboratory must be State of Washington accredited to satisfy
     Hanford testing requirements.

7.   In the event that the sampling frequency proposed by ATG is deemed
     insufficient during the permitting process by a state or federal agency of
     jurisdiction, the increased costs due to increased sampling frequency shall
     be the sole responsibility of ATG.

8.   With respect to ATG's response to WHC question 7 dated June 6, 1995, WHC
     and ATG have discussed and agree to be bound by SOW section 3.0. The mixed
     waste containers were characterized to standards in effect at the time of
     storage. Additional characterization prior to waste shipment will be
     performed by WHC only for the purpose of establishing treatability
     certification requirements and to meet DOT shipping container requirements.
     Upon receipt of the waste from WHC, for its own purposes, or at the request
     of regulators, ATG may be required to perform additional waste
     characterization. ATG acknowledges that if additional characterization is
     required prior to treatment, such effort and cost shall be the
     responsibility of ATG.

9.   ATG shall anticipate a very broad mix of organic compounds and
     radionuclides when preparing permit applications. ATG shall anticipate
     having to treat TCSA regulated PCB waste and most RCRA listed and
     characteristic wastes, with the exception of those having technology 

                                       1
<PAGE>
 
     based standards other than incineration. WHC will provide updated lists of
     inventoried materials as they are approved for public release.

10.  ATG has been provided WHC-SD-W242-002 and WHC-SD-W242-003 for future
     reference.  ATG has been provided the current Hanford Site Solid Waste
     Acceptance Criteria.

     As more current data becomes available on waste related to this contract,
     that data will be provided to ATG in electronic format to assist with their
     design and permitting tasks.

11.  ATG shall accept containers having any or all dimensions up to and
     including 8' by 8' by 11'.  Waste item size acceptance criteria is limited
     to what will fit into the containers.

12.  Containers may contain non-metal objects such as concrete and brick larger
     than 1 foot by 1 foot by 1 foot.

13.  Waste that is to be treated will have been accepted by the Hanford Site
     Central Waste Complex, the waste acceptance criteria for which are
     identified in WHC-EP-0063-4.  ATG shall be required to treat all such waste
     unless specifically excluded by mutual agreement with WHC.

14.  ATG shall conduct additional waste-specific testing as may be required for
     the PEAT process.

15.  ATG will be required to be certified as a waste generator by WHC Solid
     Waste Disposal Division.

16.  Shredding and compaction of HEPA filters is not acceptable to WHC if the
     filters are mixed waste.

17.  The minimum estimated quantity is one hundred and twenty (120) cubic meters
     of waste per year over the first five (5) year period of processing.

18.  Maximum Start Date for waste processing is five years from the date of
     award.  The waste processing's period of performance will entail a five (5)
     year baseline period plus five (5) one year options.

19.  Contract Type:  Indefinite Quantity/Fixed Unit Rate

20.  The first one hundred and twenty (120) cubic meters of waste processed each
     year during the first five years of processing will be paid for at the 1 to
     600 cubic meter unit prices. Quantities in excess of 120 cubic meters per
     year during the first five years of processing will be paid for at the 601
     to 3,585 cubic meter unit prices. Payment will be made after waste has been
     processed compliant with the terms of the purchase order.

21.  The loading and unloading of ATG's waste transport vehicles will be
     completed by WHC at Hanford only.

                                       2
<PAGE>
 
22.  WHC will provide containers which meet all Department of Transportation
     regulations for any waste manifested at the Buyer's facility.

23.  WHC will characterize the waste as needed to meet DOT and EPA requirements
     as the shipper.  Additional characterization needed to treat the waste is
     the responsibility of ATG.

24.  The waste will be staged at central location(s) at the Buyer's facility.

25.  Laboratory Analysis:  satisfying the requirements of all environmental
     regulations for treatment of the waste and providing a product which is
     ready for disposal is ATG's responsibility.  If the sample analyses
     completed in support of ATG's process are not compliant with regulatory
     requirements, it is ATG's responsibility to implement the appropriate
     corrective action.  There will be no post award price adjustment for
     compliance with regulatory requirements unless ATG can cite specific
     regulatory changes and substantiate the basis for the associated cost
     impact.

26.  The mix (contents) of projected waste to be processed as listed on the
     "Characterization of Waste - LLMW Inventory Sheets" which were previously
     provided under separate cover, shall be the basis for determining the types
     of waste to be processed under any resultant order.

     The containers listed in Table 1 are excluded from the inventory of
     existing waste because they are considered to be beyond the regulatory
     scope of the statement of work due to the presence of asbestos or due to
     high concentrations of mercury waste.

     The "Solid Waste Information and Tracking System" data for containers
     222S92-000293 and 222S-92-000166 are attached. The information on
     222S-92-000293 includes a correction in Pu-238 weight. Review of both of
     these containers reveals that neither meets the definition of transuranic
     (TRU) waste and bath are classified as low level mixed waste. Section 3 of
     the Statement of Work defines the waste to be treated. Only waste specified
     there will be made available for treatment.

     Some TSCA materials of greater than 5000 ppm PCB are included with this
     order and shall be treated by the Seller. Waste containing asbestos will
     not be included with this order and those listed on the inventory sheets
     previously provided are removed.

27.  The completion of NEPA, permitting, and licensing requirements is the
     responsibility of the Seller. The proposed pricing and estimated start date
     for waste processing shall assume the appropriate length of time to
     accommodate the environmental regulations and laws (e.g., Environmental
     Assessment with a Finding of No Significant Impact) commensurate with the
     proposed technology.

26.  The proposed pricing by ATG shall accommodate all provisions of the Service
     Contract Act.

29.  No Recycle or Reuse considerations (credit) is included in ATG's pricing.
     Recycle or Reuse has not been authorized at this time by the Department of
     Energy.

30.  The average density of the waste to be processed may be assumed to be the
     same as the waste listed on the "Characterization of Waste - LLMW Inventory
     Sheets" that ware previously provided. Should the average density of waste
     treated be different than the average density of the waste identified on
     the inventory sheets, ATG may request an equitable adjustment that is
     substantiated by valid and factual supporting documentation. WHC reserves
     the right to seek consideration if the average density of the waste allows
     a ATG to realize efficiencies not considered in the unit pricing during the
     baseline and option year(s) processing. 

31.  Waste Selection:  It is recognized that ATG must be able to provide the
     proper waste feed mixture in order to efficiently operate a thermal
     treatment facility.  To accommodate this requirement, WHC will provide a
     list of containers available for treatment by ATG.  From that list, ATG
     shall select which containers will be placed on each shipment.  The list
     will be updated as new containers are made available for shipment by WHC.

     ATG is responsible for treatment of all waste identified on the inventory
     lists.  Toward the end of the order, ideal waste mixture for optimum
     facility operation may not be available and ATG shall still be responsible
     for processing all waste provided by WHC.

                                       4

32.  Transportation (Shipment Size): It is recognized that ATG must be able to
     estimate shipment size in order to provide an accurate proposal. ATG shall
     assume all shipments of waste will contain the quantity and mix of
     containers of waste selected by ATG (number and size). Restated: all
     shipments will be of the size desired by ATG based upon the inventory
     availability.

     Hanford Site rules do not preclude loading two layers of containers on a
     truck within the limits specified by the Department of Transportation and
     Nuclear Regulatory Commission for the type of waste to be treated. The
     Hanford Site will load vehicles as directed by ATG.  The vehicle axle
     weight limits will not be exceeded and ATG will provide all necessary
     materials to secure the containers.

33.  Ash/Residue as described in the Statement of Work refers to all products of
     thermal treatment including glass or slag.  The Hanford Site Specific
     Performance Requirements specified in the Statement of Work,. Section 5.0,
     Leach Testing Requirements references the American Nuclear Society
     Procedure 16.1.  The standard 90 day test shall be used to meet this
     requirement.

34.  Generation of TRU and GTCC ash/residue:  The waste inventory contains
     radioactive elements, including transuranic constituents.  The
     concentration effect associated with volume reduction by thermal treatment
     can increase the concentration of radioactive constituents in the final
     waste form.  ATG shall administratively control the waste feed so that no
     TRU waste (as defined by the HSSWAC (WHC 1993) and no greater than Class C
     waste (in accordance with 10 CFR 61.55) is generated.

35.  ATG agrees to purchase and ready a Graphite Furnace Atomic Absorption
     Spectrometer in addition to the analytical equipment previously identified
     by ATG to be utilized in performing this work.

36.  WHC may not have funding to pay for processing earlier than 5 years
     following award.  Processing before 5 years following award will require
     written authorization from WHC.

Note:  The 600 cubic meters pricing represents 120 cubic meters per year for the
first five years of processing. To the extent that it is practical, the annual
allocation shall be 78 cubic meters of non-alpha waste and 42 cubic meters of
alpha waste, which is the same waste type ratio as the 600 cubic meter

                 SPECIAL CLAUSES FOR 8(A) TRIPARTITE CONTRACTS
                                        
Section 8(a) Award
Reference FAR 52.219-17

                         SECTION 8(a) AWARD (FEB 1990)

(a)  By execution of a contract, the Small Business Administration (SBA) agrees
     to the following:

     (1)  To furnish the supplies or services set forth in the contract
          according to the specifications and the terms and conditions by
          subcontracting with the Offeror who has been determined an eligible
          concern pursuant to the provisions of Section 8(a) of the Small
          Business Act, as amended (15 USC 637[a]).

     (2)  Except for novation agreements and advance payments, delegates to the
          U.S. Dept. of Energy, Richland, WA the responsibility for
          administering the contract with complete authority to take any action
          on behalf of the Government under the terms and conditions of the
          contract; provided, however, that the contracting agency shall give
          advance notice to the SBA before it issues a final notice terminating
          the right of the subcontractor to proceed with further performance,
          either in whole or in part, under the contract.

     (3)  That payments to be made under the contract will be made directly to
          the subcontractor by the contracting activity.

     (4)  To notify the U.S. Dept. of Energy, Richland, WA Contracting Officer
          immediately upon notification by the subcontractor that the owner or
          owners upon whom 8(a) eligibility was based plan to relinquish
          ownership or control of the concern.

(b)  The offeror/subcontractor agrees and acknowledges that it will, for and on
     behalf of the SBA, fulfill and perform all of the requirements of the
     contract.

                           CONTRACT SPECIFIC CLAUSES
                                        
Since FAR 52.219-17 omits two important clauses that would be contained in 
52.219-12 if there were a separate subcontract, SBA requests that the following
clauses be included in the contract as Contract Specific Clauses:

A.   "That Allied Technology Group, Inc. will not subcontract the performance of
     any of the requirements of the subcontract to any lower tier subcontractor
     without the prior written approval of the SBA and the Designated
     Contracting Officer of the U.S. Dept. of Energy, Richland, WA."

B.   "That Allied Technology Group, Inc., awarded a subcontract hereunder,
     shall have the right of appeal from decisions of the Contracting Officer
     cognizable under the "Disputes" clause of said contract."

     "A copy of the acceptance document and a copy of the final payment document
     will be provided to SBA."

                           VOLUME REDUCTION SERVICES
                                        

Introduction
- ------------

The U. S. Department of Energy, Richland Operations Office (RL) (hereafter
referred to as the Government in this document) is seeking the services of a
vendor to volume reduce low level waste and transport it for disposal at the
Hanford Site. Normal operations, as well as site cleanup activities at Hanford
and other Government sites, result in the generation of large volumes of low-
level radioactive waste. The Government is responsible for characterizing,
managing, and disposing of all low-level waste generated at the facility. Most
of the low level waste is currently being disposed of in shallow land burial
trenches. In this regard, the Government has a two-fold objective: to improve
the efficiency of low level waste disposal, and to preserve the valuable land
resource by employing techniques to reduce the volume of the low-level waste
before it is placed in the disposal trench.

The Government is seeking the services of vendors (hereafter referred to as the
"Contractor" in this document) with the capability to receive low-level
radioactive waste, significantly reduce the volume of the low level waste by
sorting and compacting the waste, and transport it for disposal at the Hanford
low level waste facilities.

Low level waste streams whose reduction can be enhanced using technologies not
available on the Hanford Site shall be considered for this contract; upon
development and initiation of any future reduction capabilities at Hanford, low
level waste streams which can utilize those capabilities shall be processed at
Hanford.

As appropriate, the Contractor will supply procedures, requirements, containers,
transportation, and volume reduction processing for low-level waste. After
reducing the low level waste volume, the Contractor will transport the low level
waste to Hanford. The Contractor will be required to certify:


     .    the amount of volume reduction achieved,

     .    that all low level waste received from the Government has been
          returned, and

                                                               SECTION C

     .    that the returned low level waste meets the Hanford Waste Acceptance
          Criteria for disposal.

The Contractor has the option to subcontract work which can not be performed at
Contractor's facility to other vendors. The Contractor's subcontractors (if any)
must be accomplished in accordance with Section H, H-3, FAR 52. 219-14
                                                        --------------
LIMITATION ON SUBCONTRACTING (JAN 1991) and authorized by the Contracting
- ---------------------------------------
Officer. The Government will ship only to the Contractor's one designated
receiving facility, unless, the Contractor can not accept the low level waste at
his designated facility due to a regulatory restriction.


Regulations and Requirements
- ----------------------------

Regulations and requirements applicable to low level waste packaging,
transportation, and disposal at the Hanford Reservation are included in this
document. The Contractor/s is responsible to know of the regulations and
requirements applicable to these same elements at its own facility.


Description of the Low Level Waste Materials
- --------------------------------------------

The low level wastes to be processed are dry materials, contaminated by
radioactive isotopes in concentrations less than or equal to those specified for
Category 1 waste in the Hanford Site Solid Waste Acceptance Criteria (WHC-EP-
0063, latest revision). The low level waste consists of paper, plastic, wood,
metal, glass, and general debris (such as concrete and steel) from the
decontamination and decommissioning of existing nuclear facilities.

The Government anticipates approximately 36,000 cubic feet (288,00 lbs. ) of low
level waste will require volume reduction processing for fiscal year 1995.  In
accordance with Hanford requirements, the Government must describe the isotopes
present in the low level waste and certify that they do not exceed the Hanford
Site Solid Waste Acceptance Criteria prior to shipping low level wastes from the
place where they are generated.  Low-level radioactive waste is generated
throughout the Hanford Reservation.


Services
- --------

The volume reduction services provided by the Contractor will include at least
the following:

     1.   Pick-up of low level waste materials at the generator's normal 
          load-out locations.

     (a)  The Contracting Officer may, at any time, by written order to the
          Contractor, require the Contractor to stop all, or any part, of the
          work called for by this contract for a period of 90 days after the
          order is delivered to the Contractor, and for any further period to
          which the parties may agree. The order shall be specifically
          identified as a stop-work order issued under this clause. Upon receipt
          of the order, the Contractor shall immediately comply with its terms
          and take all reasonable steps to minimize the incurrence of costs
          allocable to the work covered by the order during the period of work
          stoppage. Within a period of 90 days after a stop-work order is
          delivered to the Contractor, or within any extension of that periods

               Termination clause of this contract.

     (b)  If a stop-work order issued under this clause is canceled or the
          period of the order or any extension thereof expires, the Contractor
          shall resume work. The Contracting Officer shall make an equitable
          adjustment in the delivery schedule, the estimated cost, the fee, or a
          combination thereof, and in any other terms of the contract that may
          be affected, and the contract shall be modified, in writing,
          accordingly, if -

          (1)  The stop-work order results in an increase in the time required
               for, or in the Contractor's cost properly allocable to, the
               performance of any part of this contract; and

          (2)  The Contractor asserts its right to the adjustment within 30 days
               after the end of the period of work stoppage; provided, that, if
               the Contracting Officer decides the facts justify the action, the
               Contracting Officer may receive and act upon a proposal submitted
               at any time before final payment under this contract.

     (c)  If a stop-work order is not canceled and the work covered by the order
          is terminated for the convenience of the Government, the Contracting
          Officer shall allow reasonable costs resulting from the stop-work
          order in arriving at the termination settlement.

     (D)  If a stop-work order is not canceled and the work covered by the order
          is terminated for default, the Contracting Officer shall allow, by
          equitable adjustment or otherwise, reasonable costs resulting from the
          stop-work order.

     MONITOR (TM)
     ------------

     (a)  Performance of the work under this contract shall be subject to the
          technical direction of the "Contracting Officer's Representative (COR)
          and/or "Technical Monitor (TM)" who will be designated in writing by
          the Contracting Officer. The Contracting Officer may from time to time
          designate others, in writing, to be the COR and/or TM by letter
          without formal contract modification. The term "technical direction"
          is defined to include, without limitation:

          (1)  Directions to the Contractor which redirect the contract effort,
               shift work emphasis between work areas or tasks, require pursuit
               of certain lines of inquiry, fill in details or otherwise serve
               to accomplish the contractual "Statement of Work."

          (2)  Provision of written information to the Contractor which assists 
               in the interpretation of portions of the work description.

          (3)  Review and, where required by the contract, approval of reports
               and information to be delivered by the Contractor to the
               Government under this contract.
     
          (4)  Performance of other duties in connection with technical
               administration of the contract and monitoring of the Contractor's
               performance, as specifically designated by the Contracting
               Officer in writing.

     (b)  Technical direction must be within the scope of work stated in this
          contract. The COR nor TM has the authority to, and may not, issue any
          technical direction which:

          (1)  Constitutes an assignment of additional work outside the 
               Statement of Work.

          (2)  Constitutes a change, as defined in the Contract Clause entitled 
               "Changes - Cost-Reimbursement - Alternate 1."

          (3)  In any manner causes an increase or decrease in the final price
               or the time required for contract performance.

          (4)  Changes any of the express terms, conditions, or specifications
               of this contract.

          (5)  Interferes with the Contractor's right to perform under the terms
               and conditions of this contract.

     (c)  All technical directions shall be issued in writing by the COR or TM.

     (d)  The Contractor shall proceed promptly in accordance with technical
          directions duly issued by the COR or TM in the manner prescribed and
          within his authority under the provisions of this Subsection.

          If, in the opinion of the Contractor, any instruction or direction by
          the COR or TM is within one of the categories defined in paragraphs b.
          1 through 5 above, the Contractor shall not proceed but shall notify
          the Contracting Officer immediately and confirm such notification in
          writing within five (5) working days after receipt of any such
          instruction or direction and shall request the Contracting Officer to
          modify the contract accordingly. Upon receiving such notification from
          the Contractor, the Contracting Officer shall:

          (1)  Advise the Contractor in writing within thirty (30) days after
               receipt of the Contractor's letter that the direction is
               technical direction as defined above and does not constitute a
               change under the "Changes - Cost-Reimbursement - Alternate 1"
               clause of this contract; or

          (2)  Inform the Contractor in writing within thirty (30) days after
               receipt of the Contractor's letter not to perform the direction
               and to cancel the direction; or

          (3)  Advise the Contractor within a reasonable time that the
               Government will issue a written change order/modification.

     (e)  The Contractor shall comply with the Contracting Officer's decision,
          but may pursue its remedies under the contract clause entitled
          "Disputes-Alternate I."  If the Contractor follows an instruction or
          direction which he believes is within one of the categories in b.1
          through 5 above, without following the procedure described in (d)
          above, the Contractor does so at his own risk.

     ------------------------------------------------------------------------
     CONSULTANTS. (NOV 1991)
     -----------------------

(a)  Definitions.

     (1)  Marketing consultant means any independent contractor who furnishes
          advice, information, direction, or assistance to an offeror or any
          other contractor in support of the preparation or submission of an
          offer for a government contract by that offeror.  An independent
          Contractor is not a marketing consultant when rendering--

          (i)    Services excluded in FAR 37.204;

          (ii)    Routine engineering and technical services (such as
                  installation, operation, or maintenance of systems, equipment,

          (iii)   Routine legal, actuarial, auditing, and accounting services;
                  or

          (iv)    Training services.

     (2)  Organizational conflict of interest means that because of other
          activities or relationships with other persons, a person is unable or
          potentially unable to render impartial assistance or advice to the
          Government, or the person's objectivity in performing the contract
          work is or might be otherwise impaired, or a person has an unfair
          competitive advantage.

(b)  An individual or firm that employs, retains, or engages contractually one
     or more marketing consultants in connection with a contract, shall submit
     to the contracting officer, with respect to each marketing consultant, the
     certificates described below, if the individual or firm is notified that it
     is the apparent successful offeror.

                                                             DE-ACO6-95RL13129
                                                             SECTION I

(c)  The certificate must contain the following:

     (1)  The name of the agency and the number of the solicitation in question.

     (2)  The name, address, telephone number, and federal taxpayer
          identification number of the marketing consultant.

     (3)  The name, address, and telephone number of a responsible officer or
          employee of the marketing consultant who has personal knowledge of the
          marketing consultants involvement in the contract.

     (4)  A description of the nature of the services rendered by or to be
          rendered by the marketing consultant.

     (5)  The name, address, and telephone number of the client or clients, and
          the name of a responsible officer or employee of the marketing
          consultant who is knowledgeable about the services provided to such
          client(s), and a description of the nature of the services rendered to
          such client(s), if, based on information provided to the Contractor by
          the marketing consultant, any marketing consultant is rendering or, in
          the 12* months preceding the date of the certificate, has rendered
          services respecting the same subject matter of the instant
          solicitation, or directly relating to such subject matter, to the
          Government or any other client (including any foreign government or
          person).

     (6)  A statement that the person who signs the certificate for the prime
          Contractor has informed the marketing consultant of the existence of
          Subpart 9.5 and Office of Federal Procurement Policy Letter 89-1.

     (7)  The signature, name, title, employer's name, address, and telephone
          number of the persons who signed the certificates for both the
          apparent successful offeror and the marketing consultant.

(d)  In addition, the apparent successful offeror shall forward to the
     Contracting Officer a certificate signed by the marketing consultant that
     the marketing consultant has been told of the existence of Subpart 9.5 and
     Office of Federal Procurement Policy Letter 89-1, and the marketing
     consultant has made inquiry, and to the best of the consultant's knowledge
     and belief, the consultant has provided no unfair competitive advantage to
     the prime Contractor with respect to the services rendered or to be
     rendered in connection with the solicitation,

                                                             SECTION I

     or that any unfair competitive advantage that, to the best of the
     consultant's knowledge and belief, does or may exist, has been disclosed to
     the offeror.

(e)  Failure of the offeror to provide the required certifications may result in
     the offeror being determined ineligible for award. Misrepresentation of any
     fact may result in the assessment of penalties associated with false
     certifications or such other provisions provided for by law or regulation.

       Intellectual Property under such bid. Such right to use ATG Intellectual
       Property shall be solely for the particular bid in which ATG declines to
       participate. If a joint bid is issued to a customer and the customer
       chooses not to accept either IET's or ATG's portion of the bid, either
       IET or ATG, which ever party is accepted, can proceed independent of the
       customer rejected party so long as the rejected party's technology is not
       used in a re-issued bid.

       This section 2.6 shall survive termination of the Agreement under section
       7.1 for the term described herein.

     accepted ("Acceptance") and ATG shall be subject to all of the continuing
     payment obligations in Article 3 hereof Formal rejection must be in writing
     and may only be based on Failure of the System to be in material conformity
     with the Final Design ("Formal Rejection"). Prior to a Formal rejection,
     ATG must notify IET in writing of the specific nature of the claimed
     failure or failures of the System to materially conform to the Final
     Design. IET shall have a period of forty-five (45) days to remediate or
     agree with ATG to a schedule for remediation or achieving conformity, which
     agreement will not be unreasonably withheld by ATG. If after twenty (20)
     days of recertification of the System by IET, ATG shall not have issued a
     Formal Rejection, the System shall be deemed Accepted. If the System is
     Formally Rejected, ATG shall cause the System to be delivered to IET at its
     premises and ATG shall have no further rights with respect to the System
     except for its Intellectual Property rights set out in Article 2 hereof.

                         SPECIAL CONTRACT REQUIREMENTS

H.1  52.000-4501  MOBILIZATION AND OTHER CONTINGENCY PLANNING (CIL 83-6)

                     a.  The attention of the contractor is invited to the
                  clause in the general contract clauses entitled "CHANGES".
                  This clause permits the Contracting Officer to make changes
                  within the general scope of the contract to include the
                  definition of services, and place and time of performance.

                     b.  Among the circumstances in which the provisions of this
                  clause may be invoked is a general or limited mobilization of
                  reserve forces or an emergency which impacts upon contract
                  performance.  In the event of either eventuality, the
                  contractor will be expected to promptly take whatever measures
                  are needed to meet any new demands placed upon it.  Such
                  demands may well require increases in contractor furnished
                  property, as well as extended work hours and expansion of the
                  contract workforce.

                     c.  To ensure that Government operations which depend upon
                  the services provided hereunder can proceed with no or only
                  minimal disruption, the contractor shall during the life of
                  this contract anticipate the possibility of a mobilization or
                  similar emergency and the steps it will need to take to
                  rapidly expand its contract capabilities to meet the exigency.

H.2  52.000-4503  TRAFFIC REGULATIONS

                    ALL Contractor employees performing services under this

                    (SEP 1990)
 
                      (a) The Government, at its election, may reduce the price
                    of a fixed-price type contract or contract modification and
                    the total cost and fee under a cost-type contract or
                    contract modification by the amount of profit or fee
                    determined as set forth in paragraph (b) of this Clause if
                    the head of the contracting activity or his or her designee
                    determines that there was a violation of subsection 27(a) of
                    the Office of Federal Procurement Policy Act, as amended (41
                    U.S.C. 423), as implemented in the FAR. In the case of a
                    contract modification, the fee subject to reduction is the
                    fee specified in the particular contract modification at the
                    time of

                                      I-6

                  execution, except as provided in subparagraph (b)(5) of this
                  clause.

                    (b)  The price or fee reduction referred to in paragraph (a)
                  of this Clause shall be--

                    (1)  For cost-plus-fixed-fee contracts, the amount of the
                  fee specified in the contract at the time of award;

                    (2)  For cost-plus-incentive-fee contracts, the target fee
                  specified in the contract at the time of award,
                  notwithstanding any minimum fee or "fee floor" specified in
                  the contract;

                    (3)  For cost-plus-award-fee contracts--

                    (i)  The base fee established in the contract at the time of
                  contract award;

                    (ii) If no base fee is specified in the contract, 30 percent
                  of the amount of each award fee otherwise payable to the
                  Contractor for each award fee evaluation period or at each
                  award fee determination point.

                    (4)  For fixed-price-incentive contracts, the Government 
                  may--

                    (f) Reduce the contract target price and contract target
                  profit both by an amount equal to the initial target profit
                  specified in the contract at the time of contract award; or

                    (ii) If an immediate adjustment to the contract target price
                  and contract target profit would have a significant adverse
                  impact on the incentive price revision relationship under the
                  contract, or adversely affect the contract financing
                  provisions, the Contracting Officer may defer such adjustment
                  until establishment of the total final price of the contract.
                  The total final price established in accordance with the
                  incentive price revision provisions of the contract shall be
                  reduced by an amount equal to the initial target profit
                  specified in the contract at the time of contract award and
                  such reduced price shall be the total final contract price.

                    (5)  For firm-fixed-price contracts or contract
                  modifications, by 10 percent of the initial contract price; 10
                  percent of the contract modification price; or a profit amount
                  determined by the Contracting Officer from records or
                  documents in existence prior to the date of the contract award
                  or modification.

                    (c)  The Government may, at its election, reduce a prime
                  Contractor's price or fee in accordance with the procedures of
                  paragraph (b) of this clause for violations of the Act by its
                  subcontractors by an amount not to exceed the amount of profit
                  or fee reflected in the subcontract at the time the
                  subcontract was first definitively priced.

                    (d)  In addition to the remedies in paragraphs (a) and (c)
                  of this clause, the Government may terminate this contract or
                  modification for default. The rights and remedies of the
                  Government specified herein are not exclusive, and are in
                  addition to any other rights and remedies provided by law or
                  under this contract.

                                (End of clause)

                  CONTRACTOR DEBARRED, SUSPENDED, OR PROPOSED FOR DEBARMENT
                  (MAY 1989)

                    (a) The Government suspends or debars Contractors to protect
                  the Government's interest.  Contractors shall not enter into
                  any subcontract equal to or in excess of $25,000 with a
                  Contractor that has been debarred, suspended, or proposed for
                  debarment unless there is a compelling reason to do so.  If a
                  Contractor intends to subcontract with a party that is
                  debarred, suspended, or proposed for debarment (see FAR 9.404
                  for information on the List of Parties Excluded from
                  Procurement Programs), a corporate officer or designee of the
                  Contractor shall notify the Contracting Officer, in writing,
                  before entering into such subcontract. The notice must include
                  the following:

                    (1) The name of the subcontractor;

                    (2) The Contractor's knowledge of the reasons for the
                  subcontractor being on the List of Parties Excluded from
                  Procurement Programs;

                    (3) The compelling reason(s) for doing business with the
                  subcontractor notwithstanding its inclusion on the List of
                  Parties Excluded from Procurement Programs; and

                    (4) The systems and procedures the Contractor has
                  established to ensure that it is fully protecting the
                  Government's interests when dealing with such subcontractor in
                  view of the specific basis for the party's debarment,
                  suspension, or proposed debarment.

                    (b) The Contractor's compliance with the requirements of
                  52.209-6 will be reviewed during Contractor Purchasing System
                  Reviews (see FAR Subpart 44.3).

                  UNDER THE INTERMEDIATE-RANGE NUCLEAR FORCES (INF) TREATY (JAN
                  1990)

                    (a) The Contractor shall not deny consideration for a
                  subcontract award under this contract to a potential
                  subcontractor subject to on-site inspection under the INF
                  Treaty solely or in part because of the actual or potential
                  presence of Soviet inspectors at the subcontractor's facility
                  unless the decision is approved by the Contracting Officer.

                    (b) The Contractor shall incorporate this clause, with
                  appropriate changes to identify properly the contracting
                  parties, including this paragraph (b), in all solicitations
                  and contracts in excess of the dollar

I.67  52.212-0013 STOP-WORK ORDER  (AUG 1989)

                    (a) The Contracting Officer may, at any time, by written
                  order to the Contractor, require the Contractor to stop all,
                  or any part, of the work called for by this contract for a
                  period of 90 days after the order is delivered to the
                  Contractor, and for any further period to which the parties
                  may agree. The order shall be specifically identified as a
                  stop-work order issued under this clause. Upon receipt of the
                  order, the Contractor shall immediately comply with its terms
                  and take all reasonable steps to minimize the incurrence of
                  costs allocable to the work covered by the order during the
                  period of work stoppage. Within a period of 90 days after a
                  stop-work is delivered to the Contractor, or within any
                  extension of that period to which the parties shall have
                  agreed, the Contracting Officer shall either--

                    (1) Cancel the stop-work order; or

                    (2) Terminate the work covered by the order as provided in
                  the Default, or the Termination for Convenience of the
                  Government, clause of this contract.

                    (b) If a stop-work order issued under this clause is
                  canceled or the period of the order or any extension thereof
                  expires, the Contractor shall resume work.  The Contracting
                  Officer shall make an equitable adjustment in the delivery
                  schedule or contract price, or both, and the contract shall be
                  modified, in writing, accordingly, if--

                    (l) The stop-work order results in an increase in the time
                  required for, or in the Contractor's cost properly allocable
                  to, the performance of any part of this contract; and

                    (2) The Contractor asserts its right to the adjustment
                  within 30 days after the end of the period of work stoppage;
                  provided, that, if the Contracting Officer decides the facts
                  justify the action, the Contracting Officer may receive and
                  act upon the claim submitted at any time before final payment
                  under this contract.

                    (c) If a stop-work order is not canceled and the work
                  covered by the order is terminated for the convenience of the
                  Government, the Contracting Officer shall allow reasonable
                  costs resulting from the stop-work order in arriving at the
                  termination settlement.

                    (d) If a stop-work order is not canceled and the work
                  covered by the order is terminated for default, the
                  Contracting Officer shall allow, by the equitable adjustment
                  or otherwise, reasonable costs resulting from the stop-work
                  order.

                                (End of clause)

I.68  52.215-7000 AGGREGATE PRICING ADJUSTMENT  (APR 1985)

                    In determining whether a pricing adjustment is expected to
                  exceed $100,000, the term "pricing adjustment" shall mean "the
                  aggregate increases and/or decreases in cost plus applicable
                  profits."

                                (End of clause)

                    (a) Any supplies and services to be furnished under this
                  contract shall be ordered by issuance of delivery orders by
                  the individuals or activities designated in the Schedule. Such
                  orders may be issued from 1 July 1991 through 30 June 1992.

                    (b) All delivery orders are subject to the terms and
                  conditions of this contract.  In the event of conflict between
                  a delivery order and this contract, the contract shall
                  control.

                    (c) If mailed, a delivery order is considered "issued" when
                  the Government deposits the order in the mail.  Orders may be
                  issued orally or by written telecommunications only if
                  authorized in the Schedule.

I.70  52.216-0019 DELIVERY-ORDER LIMITATIONS  (APR 1984)


                   (a) Minimum order.  When the Government requires supplies or
                  services covered by this contract in an amount of less than 1
                  KM2, the Government is not obligated to purchase, nor is the
                  Contractor obligated to furnish, those supplies or services
                  under the contract.

                   (b) Maximum order.  The Contractor is not obligated to honor-

                   (1) Any order for a single item in excess of 450 KM2;

                   (2) Any order for a combination of items in excess of 450
                  KM2; or

                   (3) A series of orders from the same ordering office within
                  30 days that together call for quantities exceeding the
                  limitation in subparagraph (1) or (2) above.

                   (c) If this is a requirements contract (i.e., includes the
                  Requirements clause at subsection 52.216-21 of the Federal
                  Acquisition Regulation (FAR)), the Government is not required
                  to order a part of any one requirement from the Contractor if
                  that requirement exceeds the maximum-order limitations in
                  paragraph (b) above.

                   (d) Notwithstanding paragraphs (b) and (c) above, the
                  Contractor shall honor any order exceeding the maximum order
                  limitations in paragraph (b), unless that order (or orders) is
                  returned to the ordering office within 10 days after issuance,
                  with written notice stating the Contractor's intent not to
                  ship the item (or items) called for and the reasons.  Upon
                  receiving this notice, the Government may acquire the supplies
                  or services from another source.

I.71  52.216-0021 REQUIREMENTS  (APR 1984)



                    (a) This is a requirements contract for the supplies or
                  services specified, and effective for the period stated, in
                  the Schedule.  The quantities of supplies or services
                  specified in the Schedule are estimates only and are not
                  purchased by this contract.  Except as this contract may
                  otherwise provide, if the Government's requirements do not
                  result in orders in the quantities described as "estimated" or
                  "maximum" in the Schedule, that fact shall not constitute the
                  basis for an equitable price adjustment.

                    (b) Delivery or performance shall be made only as authorized
                  by orders issued in accordance with the Ordering clause.
                  Subject to any limitations in the delivery-Order Limitations
                  clause or elsewhere in this contract, the Contractor shall
                  furnish to the Government all supplies or services specified
                  in the schedule and called for by orders issued in accordance
                  with the Ordering clause. The Government may issue orders
                  requiring delivery to multiple destinations or performance at
                  multiple locations.

                    (c) Except as this contract otherwise provides, the
                  Government shall order from the Contractor all the supplies or
                  services specified in the schedule that are required to be
                  purchased by the Government activity or activities specified
                  in the schedule.

                    (d) The Government is not required to purchase from the
                  Contractor requirements in excess of any limit on total orders
                  under this contract.

                    (e) If the Government urgently requires delivery of any
                  quantity of an item before the earliest date that delivery may
                  be specified under this contract, and if the Contractor will
                  not accept an order providing for the accelerated delivery,
                  the Government may acquire the urgently required goods or
                  services from another source.

                    (f) Any order issued during the effective period of this
                  contract and not completed within that period shall be
                  completed by the Contractor within the time specified in the
                  order.  The contract shall govern the Contractor's and
                  Government's rights and obligations with respect to that order
                  to the same extent as if the order were completed during the
                  contract's effective period; provided, that the Contractor
                  shall not be required to make any deliveries under this
                  contract after 30 June 1992.

I.72  52.217-0005 EVALUATION OF OPTIONS  (JUL 1990)


                    Except when it is determined in accordance with FAR
                  17.206(b) not to be in the Government's best interests, the
                  Government will evaluate  offers for award purposes by adding
                  the total price for all options to the total price for the
                  basic requirement.  Evaluation of options will not obligate
                  the Government to exercise the option(s).

                              (End of provision)


I.73  52.217-0009 OPTION TO EXTEND THE TERM OF THE CONTRACT  (MAR 1989)

                    (a) The Government may extend the term of this contract by
                  written notice to the Contractor within one (1) year;
                  provided, that the Government shall give the Contractor a
                  preliminary written notice of its intent to extend at least 60
                  days before the contract expires.  The preliminary notice does
                  not commit the Government to an extension.

                    (b) If the Government exercises this option, the extended
                  contract shall be considered to include this option provision.

                    (c) The total duration of this contract, including the
                  exercise of any options under this clause, shall not exceed
                  five (5) years.

                  50 percent of the cost of manufacturing the supplies, not
                  including the cost of materials.

                    (c) General construction.  The concern will perform at least
                  15 percent of the cost of the contract, not including the cost
                  of materials, with its own employees.

                    (d) Construction by special trade contractors.  The concern

I.76  52.220-0001 PREFERENCE FOR LABOR SURPLUS AREA CONCERNS  (APR 1984)

                    (a) This acquisition is not a set-aside for labor surplus
                  area (LSA) concerns.  However, the offeror's status as such a
                  concern may affect (1) entitlement to award in case of tie
                  offers, or (2) offer evaluation in accordance with the Buy
                  American Act clause of this solicitation.  In order to
                  determine whether the offeror is entitled to a preference
                  under (1) or (2) above, the offeror must identify, below, the
                  LSA in which the costs to be incurred on account of
                  manufacturing or production (by the offeror or the first-tier
                  subcontractors) amount to more than 50% of the contract price.

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

                    (b) Failure to identify the locations as specified above
                  will preclude consideration of the offeror as an LSA concern.
                  If the offeror is awarded a contract as an LSA concern and
                  would not have otherwise qualified for award, the offeror
                  shall perform the contract or cause the contract to be
                  performed in accordance with the obligations of an LSA
                  concern.

I.78  52.222-0043  FAIR LABOR STANDARDS ACT AND SERVICE CONTRACT ACT--PRICE
                   ADJUSTMENT (MULTIPLE YEAR AND OPTION CONTRACTS)  (MAY 1989)

                    (a) This clause applies to both contracts subject to area
                  prevailing wage determinations and contracts subject to
                  collective bargaining agreements.

                    (b) The Contractor warrants that the prices in this contract
                  do not include any allowance for any contingency to cover
                  increased costs for which adjustment is provided under this
                  clause.

                    (c) The wage determination, issued under the Service
                  Contract Act of 1965, as amended, (41 U.S.C. 351, et seq.), by
                  the Administrator, Wage and Hour Division, Employment
                  Standards Administration, U.S. Department of Labor, current on
                  the anniversary date of a multiple year contract or the
                  beginning of each renewal option period, shall apply to this
                  contract. If no such determination has been made applicable to
                  this contract, then the Federal minimum wage as established by
                  section 6(a)(1) of the Fair Labor Standards Act of 1938, as
                  amended, (29 U.S.C. 206) current on the anniversary date of a
                  multiple year contract or the beginning of each renewal option
                  period, shall apply to this contract.

                    (d) The contract price or contract unit price labor rates
                  will be adjusted to reflect the Contractor's actual increase
                  or decrease in applicable wages and fringe benefits to the
                  extent that the increase is made to comply with or the
                  decrease is voluntarily made by the Contractor as a result of:

                    (1) The Department of Labor wage determination applicable on
                  the anniversary date of the multiple year contract, or at the
                  beginning of the 

                                     I-14
<PAGE>
 
                  renewal option period. For example, the prior year wage
                  determination required a minimum wage rate of $4.00 per hour.
                  The Contractor chose to pay $4.10. The new wage determination
                  increases the minimum rate to $4.50 per hour. Even if the
                  Contractor voluntarily increases the rate to $4.75 per hour,
                  the allowable price adjustment is $.40 per hour;

                    (2) An increased or decreased wage determination otherwise
                  applied to the contract by operation of law; or

                    (3) An amendment to the Fair Labor Standards Act of 1938
                  that is enacted after award of this contract, affects the
                  minimum wage, and becomes applicable to this contract under
                  law.

                    (e) Any adjustment will be limited to increases or decreases
                  in wages and fringe benefits as described in paragraph (c) of
                  this clause, and the accompanying increases or decreases in
                  social security and unemployment taxes and worker's
                  compensation insurance, but shall not otherwise include any
                  amount for general and administrative costs, overhead, or
                  profit.

                    (f) The Contractor shall notify the Contracting Officer of
                  any increase claimed under this clause within 30 days after
                  receiving a new wage determination unless this notification
                  period is extended in writing by the Contracting Officer.  The
                  Contractor shall promptly notify the Contracting Officer of
                  any decrease under this clause, but nothing in the clause
                  shall preclude the Government from asserting a claim within
                  the period permitted by law.  The notice shall contain a
                  statement of the amount claimed and any relevant supporting
                  data, including payroll records, that the Contracting Officer
                  may reasonably require.  Upon agreement of the parties, the
                  contract price or contract unit price labor rates shall be
                  modified in writing.  The Contractor shall continue
                  performance pending agreement on or determination of any such
                  adjustment and its effective date.

                    (g) The Contracting Officer or an authorized representative
                  shall have access to and the right to examine any directly
                  pertinent books, documents, papers and records of the
                  Contractor until the expiration of 3 years after final payment
                  under the contract.

                  environments and procedures which will safeguard the public
                  and Government personnel, property, materials, supplies, and
                  equipment exposed to contractor operations and activities;
                  avoid interruptions of Government operations and delays in
                  project completion dates; and control costs in the performance
                  of the contract.

                    (b) For these purposes, on contracts for construction or
                  dismantling, demolition, or removal of improvements, the
                  Contractor shall--

                    (l) Provide appropriate safety barricades; sign, and signal
                  lights;

                    (2) Comply with the standards issued by the Secretary of
                  Labor at 29 CFR

                                     I-15
<PAGE>
 
                  Part 1926 and 29 CFR Part 1910;

                    (3) Ensure that may additional measures the Contracting
                  Officer determines to be reasonably necessary for the purposes
                  are taken.

                  demolition or removal of improvements with any Department of
                  Defense agency or component, the Contractor shall comply with
                  all pertinent provisions of the latest version of U.S. Army
                  Corps of Engineers Safety and Health Requirements Manual, EM
                  385-1-1, in effect on the date of the solicitation.

                    (d) Whenever the Contracting Officer becomes aware of any
                  noncompliance with these requirements or any condition which
                  poses a serious or imminent danger to the health or safety of
                  the public or Government personnel, the Contracting Officer
                  shall notify the Contractor orally, with written confirmation,
                  and request immediate initiation of corrective action.  This
                  notice, when delivered to the Contractor or the Contractor's
                  representative at the work site, shall be deemed sufficient
                  notice of the noncompliance and that corrective action is
                  required.  After receiving the notice, the Contractor shall
                  immediately take corrective action.  If the Contractor fails
                  or refuses to take corrective action promptly, the Contracting
                  Officer may issue an order stopping all or part of the work
                  until satisfactory corrective action has been taken.  The
                  Contractor shall not be entitled to equitable adjustment of
                  the contract price or extension of the performance schedule on
                  any stop work order issued under this clause.

                    (e) The Contractor shall insert this clause, including this
                  paragraph (e), with appropriate changes in the designation of
                  the parties, in subcontracts.

                  services, or owned by the armed services, at the time of
                  transportation by sea.  It includes (but is not Limited to)

                  U.S.-flag vessels are not available for timely shipment; (2)
                  the freight charges are excessive or unreasonable; or (3)
                  freight charges are higher than charges to private persons for

                  below, authorization to ship in foreign-flag vessels or

                  because of matters concerning freight charges or matters
                  concerning vessel availability must be submitted in writing by
                  or through the Prime Contractor to the Contracting Officer at
                  least forty-five (45) days prior to the sailing date for the
                  shipper to meet its delivery schedules. Requests submitted
                  after such date(s) will be processed as expeditiously as
                  possible, but the failure of the appropriate official to grant
                  approvals to meet the shipper's sailing date will not of
                  itself constitute a compensable delay under this or any other
                  clause of this contract.  The request shall contain at a
                  minimum:

                    (1) Type, weight, and cube of cargo.

                  including points of contact with at Least two (2) U.S. -flag
                  carriers contacted by name and telephone number. Copies of
                  telephone notes, telegraphic and facsimile messages or
                  letters will be sufficient for this purpose.

                    (e)  The Contractor shall, within thirty (30) days after
                  each shipment covered by this clause, provide the Contracting

5.  Receipt of Property "In-Place".  Occasionally, a particular piece of excess
    -----------------------------
property would require an extraordinary conveyance to transport it to the
nearest disposal turn-in point.  Other excess property may be extremely
dangerous to transport to a turn-in point.  Sometimes, no disposal turn-in point
may have the storage capacity or regulation-conforming facilities to store
certain property. Still other property to be disposed of may be installed and
would require dismantling prior to shipment to a turn-in point.  In these and
other unusual situations. DPDO Barstow may elect to receive such property "in-
place". This means a DPDO receiving person will visit the property's location,
inspect the property, verify the turn-in documentation. and sign for
accountability of the property "in-place". while DPDO Barstow takes
accountability for the property, the responsibility for the safekeeping care,
and frequently the issue or release of property remains with the activity
turning-in the property. All requests for DPDO Barstow to receive property in-
place should be directed to the Chief, DPDO Barstow, AUTOVON 282-6568.

6.  Scheduling Turn-ins.  The receiving personnel cited in paragraph 4 above
    -------------------
should be contacted prior to shipping any property to a disposal turn-in point.
The number of pallets, truckloads, etc, and the types of property to be turned-
in should be made known to the receiving coordinator.  A delivery date will then
be scheduled.  By scheduling turn-ins, generating activities are assured of
receiving prompt disposal service.  Scheduled deliveries are given first
receipt-processing priority. Unscheduled deliveries will be Off-loaded and
receipt-

                                  Page 2 of 13                      ATTACHMENT B
<PAGE>
 
processed as scheduled workload permits. DPDO Barstow is not authorized overtime
for the purpose of receiving property. Therefore, generating activities are
encouraged to schedule their arrival at a turn-in point early enough in the day
so all property is off-loaded prior to the end of receiving hours.

7.  Unacceptable Property.  The DPDO has responsibility for disposing of all
    ---------------------

<PAGE>
 
10.  DPDO Acceptance of Accountability.  The DPDO becomes accountable for
     ---------------------------------     
property when an authorized DPDO employee signs and dates Block 8 of the DD Form
1348.1. Block 8 is not signed until a DPDO receiver has verified the property's
identity, determined its condition, and made a count of the property delivered.
The DPDO will not receipt for TIDs where the property's identity is
questionable. If the MILSTRIP condition code appears to be incorrect, the
receiver will challenge its validity by contacting the generating activity.
Quantity discrepancies will be annotated on the DD Form 1348-1 by the DPDO
receiver. The DPDO is accountable for only that quantity actually received.

11.  TID Distribution.  A minimum of four legible copies of the DD Form 1348-1
     ----------------
must accompany a turn-in.  Three copies are kept for internal DPDO processing. A
fourth copy is returned to the generating activity after the receipt has been
posted to the DPDO property accounting system.  This fourth copy, which has been
signed and dated in Block 8, is the official receipt document.

12.  Batch Lotting.  Batch lotting is the physical grouping of individual line
     -------------
items of low dollar value property and the subsequent accounting for the group
(batch lot) as a single line item of excess personal property.  The objective of
batch lotting is to reduce the cost, physical handling, and administrative time
required to process low dollar value items through the disposal process.  If
your activity turns in a large percentage of low dollar value items, it may be
cost beneficial to turn in low dollar value property by batch lot.  Paragraph
E2, Chapter IV, reference la explains batch lotting options open to generating
activities.

13.  Property Requiring Special Processing.  Reference is made to Chapter VI,
     -------------------------------------
reference 1a.  Some property, because of its peculiar nature, its potential
influence on public health, safety, or security, or its potential influence on
private industry, must be disposed of in other than a normal fashion.
Accordingly, some turn-ins may require additional documentation, special
handling, packaging, and/or storage facilities.  This category of property will
be identified on the DD Form 1348-1 by an entry in Block D (e.g., compressed gas
cylinders; lost, abandoned, or unclaimed privately owned personal property;
shelf-life property; used oil).  The most common DPDO Barstow turn-ins
requiring, special handling or additional documentation are discussed below:

      a.  Acutely Hazardous Material.  Those substances appearing in Enclosure 1
          --------------------------
Identified substances were categorized as being acutely hazardous in Part
261.33. 40 Code of Federal Regulations (CFR), Resource Conservation Recovery Act
(RCRA).  DPDO Barstow does not have the regulation-conforming storage facilities
to physically accept acutely hazardous material.  If you need to dispose of such
material, call the Chief, DPDO Barstow on AUTOVON 282-6568.

      b.  Batteries.  Special handling or reporting requirements exist for four
          ---------
types of batteries normally turned in:

          (1)  Secondary storage (lead acid).  The most prevalent example of a
               ----------------------------
               secondary storage battery is a vehicle battery. These batteries
               use sulfuric acid as an electrolyte. Sulfuric acid is an acutely
               hazardous material. Accordingly, all the electrolyte must be
<PAGE>
 
               drained from batteries prior to turn-in to the DPDO. These
               batteries trust be stacked sideways or upside-down on pallets.
               This prevents rainwater from accumulating in batteries. It is
               suggested that for safety and ease of handling that all batteries
               be banded to the pallet. The drained electrolyte must be
               containerized and treated as an acutely hazardous material.

          (2)  Nickel Cadmium (NI-CAD).  Since most NI-CAD batteries can be
               -----------------------
               rebuilt into serviceable batteries, they are ultimately offered
               for sale as usable items, To assure item identity of NI-CADs,
               they must be turned in as an item. Turn-in by NSN is preferred.
               If the NSN is unknown, they are to be turned in by LSN with the
               manufacturer, type or part number printed on the DD Form 1348-I.

          (3)  Silver Cell.  Like NI-CADs, silver cell batteries can be rebuilt
               -----------
               into serviceable batteries. Therefore, they must be turned in as
               an item in the same manner as NI-CADS. Silver cell batteries
               which cannot be rebuilt remain valuable for their silver content.
               Accordingly, they must be treated as precious metals-bearing
               items.

          (4)  Thermal.  DPDOs can not accept thermal batteries.  Any thermal
               -------
               batteries you wish to dispose of must be reported to your
               military service's item manager.

     c.   Compressed Gas Cylinders.  Compressed gas cylinders are to be turned-
          ------------------------
in in accordance with MC010330.28/NAVSUPINST 4440.1288/AFR 67-12/AR700.68.
DPDOs can not assume physical custody of cylinders containing incendiary,
poisonous, or irritant properties.  Cylinder valves must be in a closed position
and be protected (have a valve cover). Commercially owned cylinders cannot be
accepted by the DPDO. They are to be returned to the company identified on the
cylinder or processed as Lost, Abandoned, or Unclaimed Privately-Owned Personal
Property. The only compressed gas cylinders the DPDO is authorized to accept are
those with no identification markings or those identified as government-owned.
Government-owned cylinders are identified by the following serial number
prefixes stamped on the cylinder or embossed on the neckring: AF, DA, USA, USN,
N, US, US GOVT, WD, US PROPERTY, the name of a DoD or other Government agency,
or a military (MILSPEC)/ federal (FEDSPEC) specification number.

     d.   Demilitarized Items. Munitions List Items that have been demilitarized
          -------------------
prior to turn-in must have the following signed certification on the DD Form
1348-1: "I certify that the items listed hereon were demilitarized in accordance
with Item (cite appropriate item #), Appendix 4, DoD 4160.21-M-1." Normally,
only those items assigned DEMIL code G or N should be demilitarized prior to
turn-in.

     e.   Extended Ordnance.  All expended ordnance materials such as shell
          -----------------
casings, rocket launching tubes, and dummy (inert loaded) ammunition projectiles
and warheads must be certified inert by qualified EOD personnel prior to turn-
in.  All expended ordnance not certified inert will be rejected for turn-in.
     ----------------------------------------------------------------------
Signed inert certification must be on the DD Form 1348-1 as follows:  "I certify
that the items listed hereon have been inspected by me and, to the best of my
knowledge and belief, contain no items of a dangerous or hazardous nature."

                                 Page 7 of 13                       ATTACHMENT B
<PAGE>
 
     f.   Empty Containers.  A container is considered empty if no more than one
          ----------------
(1) inch of residue remains on the bottom. The stock number placed on the DD
Form 1348-1 must apply to the container itself; not the container's previous
contents. No 55 gallon drums will be accepted unless they are sealed with bungs.

          (1)  If a container held a non-hazardous material, "NON-HZ" must be
               entered in Block C of the DD Form 1348-1.

          (2)  If a container held a hazardous material and has not been triple-
               rinsed with an appropriate solvent. "HM" must be entered in Block
               C. In addition, the following must be entered in Blocks W and X
               of the DD Form 1348-1:

               (a)  "EMPTY CONTAINER"

               (b)  Everyday, common description of the container; e.g., 55-
                    gallon drum, quart can, etc.

               (c)  Stock number and generic (not brand name) name of the
                    previously held hazardous material; e.g., ethyl alcohol,
                    paint, gasoline, oil, etc.

          (3)  If a container held an acutely hazardous material (see Enclosure
                                      -----------------
               1) that has not been triple rinsed with the appropriate solvent,
               it is considered a Hazardous Waste (HW). DPDO Barstow does not
               have the regulation-conforming storage facilities to physically
               accept HW. If you have HW empty containers to dispose of call the
               Chief, DPDO Barstow on AUTOVON 282-6568.

          (4)  If a container held a hazardous material or an acutely hazardous
               material and has been triple-rinsed with an appropriate solvent,
                            ----------------------
               it is considered non-hazardous. For triple-rinsed containers, the
               words "NON-HZ/TRIPLE RINSE" must be entered in Block C, DD Form
               1348-1.

     g.   Hazardous Material (HM).  Material that exhibits any one of the
          -----------------------
following four characteristics is defined as hazardous: 1) ignitable, 2)
corrosive, 3)reactive, or 4) toxic.  When an item or scrap exhibits one or more
of these characteristics, it must be treated as a "hazardous material" (HM).
All HM must be in containers that are non-leaking and safe to handle.  Each
container must be labeled to indicate the container's contents.  The code "HM"
must be entered in Block C of the DD Form 1348-1. Any HM that is not 1) properly
packaged or containerized, 2) labeled, and 3) adequately identified on the DD
Form 1348-1 will not be accepted for turn-in until all three requirements are
met.

     h.   Hazardous Waste (HW).  Except for the list of "Pre-Determined
          --------------------
Hazardous Wastes" appearing at Enclosure 4, all material exhibiting one or more
of the four hazardous characteristics of ignitably, corrosiveness, reactivity,
or toxicity is considered as hazardous material (HM) at the time of turn-in for
disposal.  If DPDO cannot redistribute HM to another government agency or sell
it, the HM is then declared a hazardous waste (HW).  Used HM stands a good
chance of being declared a HW.  Therefore, the following additional
documentation should appear on the
<PAGE>
 
DD Form 1348-1 for used HM.  Enclosure 5 is a sample TID for the turn-in of used
HM.

          (1)  Block A must contain the turn-in activity's Environmental
               Protection Agency's (EPA) identification number. This number may
               be obtained from your base environmental office. The telephone
               number of the office responsible for the turn-in must also be
               listed.

          (2)  Block B must contain the disposal activity's EPA identification
               number and telephone number. The following numbers apply:

               (a)  Nebo (DPDO Barstow): EPA #CA8170024261. Telephone 282-6564.

               (b)  Yermo (DPDO Barstow): EPA #CA8170090023. Telephone 282-7312.

numbers in Blocks A and B and the following additional entries:

          (5)  Block C.  Enter "HW".

          (6)  Block D.  Enter EPA Hazardous Waste Number.

When HW is transported over public highways to your servicing disposal activity,
the following additional entries on the DD Form 1348-1 are required and must be
accompanied by a properly filled out State of California Hazardous Waste
Manifest. See Enclosure 6 for manifest instructions.

          (7)  Block U.  Enter six character (2 alpha, 4 numeric) identification
number as shown in 49 CFR, Part 172.

          (8)  Blocks AA and BB. Enter EPA licensed transporter's name and his
               EPA identification number.

          (9)  Block CC. Have transporter sign and date upon his receipt of the

<PAGE>
 
     i.   Lost, Abandoned, or Unclaimed Privately-Owned Personal Property.
          ---------------------------------------------------------------
Paragraph 856, reference Ia should be read prior to initiating any action to
dispose of lost, abandoned or unclaimed privately-owned personal property
(LAPP).  The DPDO can not accept LAPP unless the DD Form 1348-1 is accompanied
by one of two supporting documents:

          (1)  A notarized release document in the format of Enclosure 7 signed
               by the owner of LAPP, or
                                     -- 

          (2)  A Board of Officers Findings. These findings must include a
               written, dated, itemized inventory list which includes the fair
               market value of each item and the name of the owner, if known. If
               assistance is required to determine the fair market value, call
               the DPDO Sales Preparation Branch, AUTOVON 282-6561.

          (3)  When a vehicle is to be disposed of, a statement that indicates
               there is no lien against the vehicle or a release statement from
               the lienholder must accompany the Owner's Release Document or the
               Board of Officers Findings.

     j.   Nonappropriated Fund (NAF) Property.  The DD Form 1348-1 for NAF
          -----------------------------------
property must contain a certification that the property was procured with
nonappropriated funds. The applicable funds account number must also be placed
on the TID. The certification and fund citation should be entered in Blocks BB-
EE. "NAF" should be entered in Block Y. The unit price entered on the TID must
be the same as that recorded in the financial/accounting records of the fund
account.

     k.   Precious Metals and Precious Metals-Bearing Items.
          -------------------------------------------------

          (1)  Quantities of fine precious metals and silver recovered from hypo
               solution may be reported directly to the Precious Metals Recovery
               Facility-Earle, Naval Ammunition Depot Earle, Bldg. C-38, Colts
               Neck, NJ 07722, AUTOVON.449-1289. Fine precious metals and
               recovered silver may also be turned in directly to a DPDO site.
               The turn-in documentation requirements are the same as for scrap
               material. Weights entered on the DD Form 1348-1 should be
               carefully measured using the appropriate measure of weight
               (grains, grams, or troy ounces). Fine precious metals/recovered
               silver will be weighed in immediately upon receipt, in the
               presence of your truck driver, by the DPDO's Precious Metals
               Monitor or by the 0S8 Chief. Any discrepancies between the
               received weight and the weight entered by the generating activity
               on the TID is the responsibility of the generating activity. DPDO
               Barstow will not initiate Reports of Discrepancies (ROD) for
               erroneous weights originally entered on the TID by the generating
               activity. However, such weight discrepancies may be reported to
               the appropriate military investigative service (CID, OSI, NIS)
               for their action.

          (2)  Many items, particularly electronic components, contain much
               economically recoverable precious metals. The words "PRECIOUS
               METALS" should be entered in Block D if precious metals content
               is known or even suspected. Often, these precious metals are not
<PAGE>
 
               externally visible. It is requested that users of an item
               containing concealed precious metals write any available
               information about the presence, type, and location of the
               precious metals on the DD Form 1348-1.

          (3)  Any questions regarding the general precious metals recovery
               program may be directed to Sally Wigmore, Southern California-
               Nevada Precious Metals Area Representative (PMAR), at DPDO San
               Diego, Bldg. 193, P. 0. Box 337, Imperial Beach, CA 92032. If
               your activity needs a silver recovery unit placed in a
               dispensary, dental clinic, photo lab, print plant, micro film and

     1.   Scrap.  Scrap is defined as having no value except for its basic
          -----
material content.

          (1)  Scrap and "salvage" are not the same thing. Salvage has some
               value other than its basic material content. While salvage is no
               longer fit for its originally intended use, other uses may be
               made of the salvage. A stripped vehicle is a good example of
               salvage. While the stripped vehicle cannot be used as originally
               intended, it has salvage value as a target for artillery or
               bombing missions. Therefore, salvage must be turned in as usable
               property; i.e., by stock number, unit of issue, quantity, etc.
               Salvage should be supply condition (MILSTRIP) coded "H".

          (2)  Any material identified by a stock number must be turned in as
               usable property regardless of the material's condition. If the
               material has no value except for its basic material content, the
               DPDO will downgrade it to scrap. The generating activity will
               receive credit for a usable property turn-in.

          (3)  Since the value of scrap is its basic material content, it is
               essential that the integrity of this basic content be maintained.
               The Government receives sales proceeds in direct proportion to
               the extent a scrap accumulation is one type of material. This
               means commingling of different basic material contents is to be
               avoided. The way to avoid commingling of scrap is to segregate
               scrap as it is generated. In a production shop, scrap can easily
               be segregated as it is generated by placing a container for each
               type of scrap near the scrap generating operation. Segregation of
               scrap as it is produced is further discussed in Chapter IV,
               reference 1c.

          (4)  Paragraph E3a, reference la states, "Initial segregation of scrap
               is the responsibility of the generating unit to the maximum
               extent feasible." DPDO Barstow strongly supports this DoD policy.
               DPDO personnel are available to assist you in achieving
               segregation at the source. If assistance is needed in determining
               the degree of

                                 Page 11 of 13                     ATTACHMENT B
<PAGE>
 
               segregation required, in obtaining containers for segregated
               scrap collection, or optimal container placement, call the
               scrapyard foreman or OSB Chief servicing your installation.
               Issuance of a base order pertaining to the segregated collection
               of scrap as it is generated is a strong step towards implementing
               the DoD policy of segregation at the source.

          (5)  At a minimum, all metal scrap must be segregated into at least
               four categories:

               a.   Light ferrous (less than 1" thick, such as sheet metal,
                    steel strapping, and steel cans),

               b.   Heavy ferrous (more than 1" thick, such as I-beams, engine
                    blocks, rails),

               c.   Nonferrous (aluminum, brass, copper),

               d.   Expended ordnance (shell casings, rocket tubes, dummy
                    projectiles).

               Within the nonferrous category, further segregation into the
               basic material contents should be made. Expended ordnance scrap
                                                       -----------------------
               will not be accepted unless it has been certified inert, in
               -----------------------------------------------------------
               writing, by qualified EOD personnel. Turn-ins not segregated to
               -----------------------------------  
               the minimum standards specified above will be rejected.

     m.   Transformers, Capacitors, and Transformer/Capacitor Fluids. Many
          ----------------------------------------------------------
transformers and capacitors use the chemical Polychlorinated Biphenyls (PCB) as
a cooling agent. PCB is suspected of causing cancer. In the state of California,
any material with a PCB concentration of seven parts per million (ppm) or
greater is considered "PCB material." The DPDO and OSBs do not have the
conforming storage required for PCB material storage. Accordingly, the DPDO/OSB
will not accept physical custody for any PCB material (PCB concentration greater
or equal to 7 ppm). DPDO Barstow will accept accountability of PCB material
received in-place (off DPDO site) provided a laboratory analysis showing an
item's PCB concentration in ppm is attached to the DD Form 1348-1. No DPDO
accountability will be accepted unless the ppm is known, in addition,
accountability will not be accepted if PCB material is not properly packaged or
labeled (including a PCB Warning label). Material with a PCB concentration of
less than 7 ppm is considered non-PCB material and will be physically accepted
by the DPDO/OSB provided a laboratory analysis showing less than 7 ppm is
attached to the DD Form 1348-1. Non-PCB material must be properly packaged and
labeled for DPDO acceptance. PCB ppm should be entered in Block D.

     n.   Small Arms. All DoD small arms are registered by serial number in the
          ----------
DoD Small Arms Serialization Program. Each military service and DLA maintains a
Small Arms Registry. No small arms turn-ins/shipments are to be made without the
prior knowledge of the appropriate small arms registry. Chapter III, reference
lb devotes itself to DoD policy on the disposal of small arms. Currently, there
is a DoD moratorium on the disposal of small arms. The DPDO OSB cannot accept
                                                   --------------------------
any small arms, no matter what the generating activity's circumstances are. No

exceptions will be granted. Questions concerning this DoD moratorium may be

     o.   Typewriters. The following information is to be entered on the DD Form
          -----------
1348-1 when typewriters are turned in:  make, model, type, (standard, silent,
noiseless, portable, manual, or electric), carriage width, typeface, and serial
number. Typewriter turn-ins that do not have the information listed above on the
TID will be refused. Paragraph B101, Chapter VI, reference 1a applies.

     p.   Used Oil. Used oil is differentiated from "waste oil" in that used oil
          --------
has reuse or sales value. Used oil becomes waste oil when it has no reuse or
sales value. Used oil turn-ins must be documented as an used hazardous material
(HM). See paragraph 13h above and Enclosure 8 for a sample DD form 1348-1.

          (1)  Used oil is disposed of in-place. It may be disposed of on a
               continual or on a one-time basis, depending on how it is
               generated. If used oil is generated fairly regularly in salable
               quantities, a term contract may be arranged to have the
               contractor pick up whenever the oil custodian notifies the
               contractor to do so. Under this arrangement, the custodian must
               measure or weigh out the oil delivered, fill out delivery
               documents, and forward the delivery documents to DPDO Barstow.

          (2)  Pursuant to the DoD Oil Recycling and Reuse Program (see
               paragraph B70.1, Chapter VI, reference 1a), net proceeds from the
               sale of used oil will be deposited to the account specified by
               the turning-in activity on the TID. No proceeds will be
                                                   -------------------
               distributed to the turning-activity unless the fund account is
               -------------------------------------------------------------- 
               cited on the DD Form 1348-1. Enter the account number in Blocks
               ---------------------------
               BB-EE.

          (3)  The State of California considers used oils generated by
               government agencies as hazardous waste (HW). In order to comply
               with the State's ruling, all used oil removed from your base must
               be manifested as a HW. The sales contractor removing your used
               oil must present a properly filled out State of California
               Hazardous Waste Manifest. The person(s) you have designated to
               fill out delivery documents must sign this manifest as the TSDF
               (transfer/storage/disposal facility), using your base's EPA
               identification number. Enclosure 6 is the State of California's
               instructions on the use of the Hazardous Waste Manifest.

     q.   Vehicles. The following information must be attached to the DD Form
          --------
1348-1 when vehicles having commercial application in Federal Supply Group (FSG)
23, 24, 38, and 39 are turned in. If the following information is not provided,
the turn-in will be refused. Paragraph 1022, Chapter VI, reference 1a applies.

          (1)  List and value of any major components that are missing (or have
               been reclaimed) such as engine, transmission, differential,
               wheels, axles, or doors, which would impair the utility of the
               vehicle, regardless of the other repairs that are necessary.

          (2)  One-time cost of repairs (parts and labor).

          (3)  The vehicle maintenance record.

                                  ATG INC.
                     1998 STOCK OWNERSHIP INCENTIVE PLAN



ARTICLE 1.  PURPOSE

         The purpose of this 1998 Stock Ownership Incentive Plan ("Plan") is to
advance the interests of ATG Inc., a California corporation ("Company"), and its
subsidiaries by encouraging employees who will largely be responsible for the
long-term success and development of the Company to acquire and retain an
ownership interest in the Company. The Plan is also intended to provide
flexibility to the Company in attracting and retaining such employees and
stimulating their efforts on behalf of the Company.

ARTICLE 2.  DEFINITIONS AND CONSTRUCTION

         2.1 Definitions. As used in the Plan, terms defined parenthetically
immediately after their use or otherwise herein shall have the respective
meanings provided by such definitions, and the terms set forth below shall have
the following meanings (in either case, such terms shall apply equally to both
the singular and plural forms of the terms defined):

                  2.1.1 "Award" shall mean, individually or collectively, a
grant under the Plan of Options, Restricted Stock or Performance Units.

                  2.1.2 "Board" shall mean the Board of Directors of the
Company.

                  2.1.3 "Cause" shall mean, unless otherwise defined in an
agreement evidencing an Award, a felony conviction of a Participant or the
failure of a Participant to contest prosecution for a felony, or a
Participant's willful misconduct or dishonesty, or the Participant's gross
insubordination or willful neglect of duty, any of which is determined by the
Board to be directly and materially harmful to the business or reputation of
the Company or its Subsidiaries.

                  2.1.4 A "Change in Control" shall mean any of the following
events:
                          (a) An acquisition (other than directly from the
Company) of any voting securities of the Company ("Voting Securities") by any
Person immediately after which such Person has Beneficial Ownership (within
the meaning of 

                                      -1-
<PAGE>
 
Rule 13d-3 promulgated under the Exchange Act) of 30% or more of the combined
voting power of the Company's then outstanding Voting Securities; provided,
however, that in determining whether a Change in Control has occurred, Voting
Securities which are acquired in a Non-Control Acquisition (as hereinafter
defined) shall not constitute an acquisition which would cause a Change in
Control. A Non-Control Acquisition shall mean acquisition by (i) the Company
or any Subsidiary, (ii) an employee benefit plan (or a trust forming a part
thereof) maintained by the Company or any Subsidiary or (iii) any Person in
connection with a Non-Control Transaction (as hereinafter defined).

                          (b) The individuals who, as of the Effective Date
(as hereinafter defined), are members of tho Board ("Incumbent Board") cease
for any reason to constitute at least a majority of the Board; provided,
however, that if the election, or nomination for election by the Company's
shareholders, of any new director was approved by a vote of at least a
majority of the Incumbent Board, such new director shall, for purposes of the
Plan, be considered as a member of the Incumbent Board; provided, further,
however, that no individual shall be considered a member of the Incumbent
Board if such individual initially assumed office as a result of either an
actual or threatened election contest (as described in Rule 14a-11 promulgated
under the Exchange Act) or other actual or threatened solicitation of proxies
or consents by or on behalf of a Person other than the Board ("Proxy Contest")
including by reason of any agreement intended to avoid or settle any such
election contest or Proxy Contest; or

                           (c)  Approval by shareholders of the Company of:

                                (i)  A merger, consolidation or reorganization
involving the Company, unless such is a Non-Control Transaction. For purposes of
the Plan, the term "Non-Control Transaction" shall mean a merger, consolidation
or reorganization of the Company in which:

                                     (A) the shareholders of the Company
immediately before such merger, consolidation or reorganization, own, directly
or indirectly immediately following such merger, consolidation or
reorganization, at least a majority of the combined voting power of the
outstanding voting securities of the corporation resulting from such merger,
consolidation or reorganization ("Surviving Corporation") in substantially the
same respective proportions as their ownership of the Voting Securities
immediately before such merger, consolidation or reorganization;

                                      -2-
<PAGE>
 
                                      (B) the individuals who were members of
the Board immediately prior to the execution of the agreement providing for
such merger, consolidation or reorganization constitute at least a majority of
the members of the board of directors of the Surviving Corporation; and

                                      (C) no Person (other than the Company,
any Subsidiary of the Company, any employee benefit plan (or a trust forming a
part thereof) maintained by the Company, the Surviving Corporation or any
Subsidiary of the Company, or any Person who, immediately prior to such
merger, consolidation or reorganization had Beneficial Ownership (within the
meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of
the then outstanding Voting Securities) has Beneficial Ownership of 20% or
more of the combined voting power of the Surviving Corporation's then
outstanding voting securities;

                                (ii) A complete liquidation or dissolution of
the Company; or

                                (iii) An agreement for the sale or other
disposition of all or substantially all of the assets of the Company to any
Person (other than a transfer to a Subsidiary).

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur
solely because any Person ("Subject Person") acquired Beneficial Ownership of
more than the permitted amount of the outstanding Voting Securities as a result
of the acquisition of Voting Securities by the Company which, by reducing the
number of Voting Securities outstanding, increases the proportional number of
shares Beneficially Owned by the Subject Person; provided, however, that if a
Change in Control would occur (but for the operation of this sentence) as a
result of the acquisition of Voting Securities by the Company, and after such
share acquisition by the Company the Subject Person becomes the Beneficial Owner
of any additional Voting Securities which increases the percentage of the then
outstanding Voting Securities Beneficially Owned by the Subject Person, then a
Change in Control shall be deemed to occur.

                  2.1.5 "Code" shall mean the Internal Revenue Code of 1986, as
amended from time to time, or any successor thereto.

                  2.1.6 "Disability" shall mean the total disability as
determined by the Board in accordance with standards and procedures similar to
those under the Company's long-term disability plan, or, if none, a physical or
mental infirmity which the Board determines impairs the Participant's ability to
perform substantially his or her duties for the Company and its Subsidiaries
for a period of 180 consecutive days.

                  2.1.9 "Fair Market Value" of the Shares shall mean, as of any
applicable date, the closing sale price of the Shares on the NASDAQ National
Market or any national or regional stock exchange on which the Shares are
traded, or if no such reported sale of the Shares shall have occurred on such
date, on the next preceding date on which there was such a reported sale. If
there shall be any material alteration in the present system of reporting sale
prices of the Shares, or if the Shares are not included in the NASDAQ National
Market or listed on a national or regional stock exchange, the Fair Market Value
of the Shares as of a particular date shall be determined by such method as
shall be determined by the Board.

                  2.1.10 "ISOs" shall have the meaning given such term in
Section 6.1.

any restrictions on or conditions to the Award, which need not be identical;

                  3.2.4 cancel or modify, with the consent of the Participant,
outstanding Awards and to grant new Awards in substitution therefor;

                  3.2.5 accelerate the exercisability of any Award, for any
reason;

                  3.2.6 construe and interpret the Plan and any agreement or
instrument entered into under the Plan;

                  3.2.7 establish, amend and rescind rules and regulations for
the Plan's administration; and

                  3.2.8 amend the terms and conditions of any outstanding Award
to the extent such terms and conditions are within the discretion of the Board
as provided in the Plan.

                                      -6-

The Board shall make all determinations which may be necessary or advisable for
the administration of the Plan. To the extent permitted by law and Rule 16b-3
promulgated under the Exchange Act, the Board may delegate its authority
hereunder.

                  3.2.9 Decisions Binding. All determinations and decisions made
by the Board pursuant to the provisions of the Plan, and all related orders or
resolutions of the Board, shall be final, conclusive and binding for all
purposes upon all persons, including the Company, its shareholders, Employees,
Participants and their estates and beneficiaries.

         3.3 Section 16 Compliance; Bifurcation of Plan. It is the intention of
the Company that the Plan and the administration of the Plan comply in all
respects with Section 16(b) of the Exchange Act and the rules and regulations
promulgated thereunder, if such rules and regulations are applicable to the
Company. If any Plan provision, or any aspect of the administration of the Plan,
is found not to be in compliance with Section 16(b) of the Exchange Act, the
provision or administration shall be deemed null and void, and in all events the
Plan shall be construed in favor of its meeting the requirements of Rule 16b-3
promulgated under the Exchange Act. Notwithstanding anything in the Plan to the
contrary, the Board, in its discretion, may bifurcate the Plan so as to
restrict, limit or condition the use of any provision of the Plan to
Participants who are subject to Section 16 of the Exchange Act without so
restricting, limiting or conditioning the Plan with respect to other
Participants. Directors and officers who fall within the definition of "officer"
under Rule 16a-1(f) promulgated under the Exchange Act shall deliver to the
Corporate Secretary of the Company an executed notice of his/her intention to
sell Shares acquired directly or indirectly hereunder. Such notice, in which
there shall be specified the number of Shares which are to be sold and the date
such Shares were acquired, shall be provided at least one full business day in
advance of the proposed date of sale.

ARTICLE 4.        SHARES AVAILABLE UNDER THE PLAN

         4.1 Number of Shares. Subject to adjustment as provided in Section 4.3,
the maximum number of Shares reserved for issuance under this Plan shall be Five
Hundred Thousand (500,000). Any Shares issued under the Plan may consist, in
whole or in part, of authorized and unissued Shares or treasury Shares. If and
to the extent an Award shall expire or terminate for any reason without having
been exercised in full (including a cancellation and re-grant of an Option), or
shall be forfeited, without, in either case, the Participant having realized
any of the economic benefits of a shareholder (such as the receipt of
dividends or other distributions paid on Shares of Restricted Stock), the
Shares (including Restricted Stock) associated with such Awards shall again
become available for Award under the Plan.

                                      -7-
<PAGE>
 
         4.2 Shares of Restricted Stock Available Under the Plan. Subject to
adjustment as provided in Section 4.3, the number of Shares which may be the
subject of Awards granted in the form of Restricted Stock is limited to a
maximum of Two Hundred Fifty Thousand (250,000) Shares.

         4.3 Adjustments in Authorized Shares and Outstanding Awards. In the
event of a merger, reorganization, consolidation, recapitalization,
reclassification, split-up, spin-off, stock dividend, stock split, reverse stock
split, cash dividend, property dividend, share repurchase, share combination,
share exchange, or other fundamental change in the corporate structure of the
Company affecting the Shares, the Board may substitute or adjust the total
number and class of Shares or other stock or securities which may be issued
under the Plan, and the number, class and/or price of Shares subject to
outstanding Awards, as it determines to be appropriate and equitable to prevent
dilution or enlargement of the rights of Participants and to preserve, without
increasing, the value of any outstanding Awards; and further provided, that the
number of Shares subject to any Award shall always be a whole number. In the
case of ISOs, such adjustments shall be made in such a manner so as not to
constitute a "modification" within the meaning of section 424(h)(3) of the Code
and only to the extent otherwise permitted by sections 422 and 424 of the Code.

ARTICLE 5.   ELIGIBILITY AND PARTICIPATION

         All Employees of the Company and its Subsidiaries are eligible to
receive Awards under the Plan. In selecting Employees to receive Awards under
the Plan, as well as in determining the number of Shares subject to, and the
other terms and conditions applicable to, each Award, the Board shall take into
consideration such factors as it deems relevant in promoting the purposes of the
Plan, including the duties of the Employees, their present and potential
contribution to the success of the Company and their anticipated number of years
of active service remaining with the Company or a Subsidiary.

ARTICLE 6.   STOCK OPTIONS

         6.1 Grant of Options. Subject to the terms and provisions of the Plan,
the Board may grant Options to Participants at any time and from time to time,
in the form of options which are intended to qualify as incentive stock options
within the meaning of section 422 of the Code ("ISOs"), Options which are not
intended to so qualify ("NQSOs"), or a combination thereof.

         6.2 Option Agreement. Each Option shall be evidenced by an Option
Agreement that shall specify the Option Exercise Price, the duration of the
Option, the 

                                      -8-
<PAGE>
 
number of Shares to which the Option relates and such other provisions as the
Board may determine which are required by the Plan. The Option Agreement shall
also specify whether the Option is intended to be an ISO or a NQSO and shall
include such provisions applicable to the particular type of Option granted.

         6.3 Duration of Options. Each Option shall expire at such time as is
determined by the Board at the time of grant ("Expiration Date"); provided,
however, that no Option shall be exercised later than the tenth anniversary of
its grant (fifth anniversary, in the case of an ISO granted to a Ten Percent
Shareholder).

         6.4 Exercise of Options. Options shall be exercisable at such times and
be subject to such restrictions and conditions as the Board shall approve at the
time of grant, which need not be the same for each grant or for each
Participant. Options shall be exercised by delivery to the Company of a written
notice of exercise, setting forth the number of Shares with respect to which the
Option is to be exercised and accompanied by full payment of the Option Exercise
Price and all applicable withholding taxes.

         6.5 Payment of Option Exercise Price. The Option Exercise Price for
Shares as to which an Option is exercised shall be paid to the Company in full
at the time of exercise either (a) in cash in the form of currency or other cash
equivalent acceptable to the Company, (b) by rendering Shares having a Fair
Market Value at the time of exercise equal to the Option Exercise Price, (c) any
other reasonable consideration that the Board may deem appropriate or (d) by a
combination of the forms of consideration described in (a), (b) and (c) of this
Section 6.5. The Board may permit the cashless exercise of Options, subject to
applicable securities law restrictions and the requirements of Regulation T
promulgated by the Federal Reserve Board, or by any other means which the Board
determines to be consistent with the Plan's purpose and applicable law; except
that in the case of any Participant subject to Section 16(b) of the Exchange Act
such cashless exercise of his or her Option may not occur within six months of
the date of grant of such Option, to the extent such exercise during such
six-month period would not be exempted from Section 16(b) of the Exchange Act by
virtue of Rule 16b-3 promulgated thereunder.

         6.6 Vesting Upon Change in Control. Upon a Change in Control, any then
outstanding Options held by Participants shall become fully vested and
immediately exercisable.

         6.7 Termination of Employment. If the employment of a Participant is
terminated for Cause, all then outstanding Options of such Participant, whether
or not exercisable, shall terminate immediately. If the employment of a
Participant is terminated for any reason other than for Cause, death, Disability
or Retirement, to the 

                                      -9-
<PAGE>
 
extent then outstanding Options of such Participant are exercisable, such
Options may be exercised by such Participant or such Participant's personal
representative at any time prior to the Expiration Date of the Options or
within 60 days after the date of such termination of employment, whichever is
earlier. In the event of the Retirement of a Participant, to the extent then
outstanding Options of such Participant are exercisable, such Options may be
exercised by the Participant (a) in the case of NQSOs, within two years after
the date of Retirement and (b) in the case of ISOs, within 90 days after
Retirement; provided, however, that no such Options may be exercised on a date
subsequent to their Expiration Date. In the event of the death or Disability
of a Participant while employed by the Company or a Subsidiary, all then
outstanding Options of such Participant shall become fully vested and
immediately exercisable, and may be exercised at any time (x) in the case of
NQSOs, within two years after the date of death or determination of Disability
and (y) in the case of ISOs, within one year after the date of death or
determination of Disability; provided, however that no such Options may be
exercised on a date subsequent to their Expiration Date. In the event of the
death of a Participant, the Option may be exercised by the person or persons
to whom rights pass by will or by the laws of descent and distribution, or if
appropriate, the legal representative of the deceased Participant's estate. In
the event of the Disability of a Participant, the Option may be exercised by
the Participant, or if such Participant is incapable of exercising the Option,
by such Participant's legal representative.

ARTICLE 7.   RESTRICTED STOCK

         7.1 Grant of Restricted Stock. Subject to the terms and provisions of
the Plan, the Board may grant shares of Restricted Stock to Participants at any
time and from time to time and upon such terms and conditions as it may
determine. The purchase price per share, if any, of Restricted Stock granted
shall be determined by the Board, but shall not be less than the par value per
Share.

         7.2 Restricted Stock Agreement. Each Restricted Stock grant shall be
evidenced by a Restricted Stock Agreement which shall specify the Restriction
Period, the number of shares of Restricted Stock granted and such other
provisions as the Board may determine and which are required by the Plan.

         7.3 Non-Transferability of Restricted Stock. Except as provided in
this Article 7, shares of Restricted Stock may not be sold, transferred,
pledged, assigned or otherwise alienated or hypothecated until the end of the
applicable Restriction Period as specified in the Restricted Stock Agreement,
or upon earlier satisfaction of any other conditions determined at the time of
grant specified in the Restricted Stock Agreement.

                                      -10-
<PAGE>
 
         7.4 Other Restrictions. The Committee may impose such other
restrictions on any shares of Restricted Stock as it may deem advisable,
including, without limitation, restrictions based upon the achievement of
Performance Goals, years of service and/or restrictions under applicable Federal
or state securities laws. The Committee may provide that any share of Restricted
Stock shall be held (together with a stock power executed in blank by the
Participant) in custody by the Company until any or all restrictions thereon
shall have lapsed.

         7.5 Forfeiture. The Committee shall determine and set forth in a
Participant's Restricted Stock Agreement such events upon which a Participant's
shares of Restricted Stock shall be forfeitable, which may include, without
limitation, the termination of a Participant's employment during the Restriction
Period or the nonachievement of Performance Goals. Any such forfeited shares of
Restricted Stock shall be immediately returned to the Company by the
Participant, and the Participant shall only receive the amount, if any, paid by
the Participant for such Restricted Stock.

         7.6 Certificate Legend. In addition to any legends placed on
certificates pursuant to Section 7.4, each certificate representing shares of
Restricted Stock shall bear the following legend:

                  "The sale or other transfer of the shares represented by this
                  Certificate, whether voluntary, involuntary or by operation of
                  law, is subject to certain restrictions on transfer as set
                  forth in the ATG Inc. 1998 Stock Ownership Incentive Plan, and
                  in the related Restricted Stock Agreement. A copy of the Plan
                  and such Restricted Stock Agreement may be obtained from the
                  Secretary of ATG Inc."

         7.7 Lapse of Restrictions Generally. Except as otherwise provided in
this Article 7, shares of Restricted Stock shall become freely transferable by
the Participant and no longer subject to forfeiture after the last day of the
Restriction Period, provided however, that if the restriction relates to the
achievement of a Performance Goal, the Restriction Period shall not end until
the Board has certified in writing that the Performance Goal has been meet. Once
the shares of Restricted Stock are released from their restrictions, the
Participant shall be entitled to have the legend required by Section 7.6 removed
from the Participant's share certificate, which certificate shall thereafter
represent freely transferable and nonforfeitable Shares free from any and all
restrictions under the Plan.

         7.8 Lapse of Restrictions Upon Change in Control. Upon a Change in
Control, any restrictions and other Plan conditions pertaining to then
outstanding shares of Restricted Stock held by Participants, including, but not
limited to, vesting 

                                      -11-
<PAGE>
 
requirements, shall lapse and such Shares shall thereafter be immediately
transferable and nonforfeitable.

         7.9 Voting Rights: Dividends and Other Distributions. During the
Restriction Period, Participants holding shares of Restricted Stock may exercise
full voting rights, and shall, unless the Board exercises its discretion as
provided in Section 7.10, be entitled to receive all dividends and other
distributions paid with respect to such Restricted Stock. If any dividends or
distributions are paid in Shares, the Shares shall be subject to the same
restrictions as the shares of Restricted Stock with respect to which they were
paid.

         7.10 Treatment of Dividends. At the time shares of Restricted Stock are
granted to a Participant, the Board may, in its discretion, determine that the
payment of dividends, or a specified portion thereof, declared or paid on such
shares shall be deferred until the lapse of the restrictions applicable to such
shares, in which event such deferred dividends shall be held by the Company for
the account of the Participant. In the event of such deferral, there may be
credited at the end of each year (or portion thereof) interest on the amount of
the account during the year at a rate per annum as the Board, in its discretion,
may determine. Deferred dividends, together with interest accrued thereon, if
any, shall be (a) paid to the Participant upon the lapse of restrictions on the
shares of Restricted Stock as to which the dividends related or (ii) forfeited
to the Company upon the forfeiture of such shares by the Participant.

         7.11 Termination of Employment. If the employment of a Participant is
terminated for any reason other than death or Disability prior to the expiration
of the Restriction Period applicable to any shares of Restricted Stock then held
by the Participant, such shares shall thereupon be forfeited immediately by the
Participant and returned to the Company, and the Participant shall only receive
the amount, if any, paid by the Participant for such Restricted Stock. If the
employment of a Participant is terminated as a result of death or Disability
prior to the expiration of the Restriction Period applicable to any shares of
Restricted Stock then held by the Participant, any restrictions and other
conditions pertaining to such shares then held by the Participant, including,
but not limited to, vesting requirements, shall immediately lapse and such
Shares shall thereafter be immediately transferable and nonforfeitable.
Notwithstanding anything in the Plan to the contrary, except in the case of
Restricted Stock for which a Performance Goal must be achieved, the Board may
determine, in its sole discretion, in the case of any termination of a
Participant's employment other than for Cause, that the restrictions on some or
all of the shares of Restricted Stock awarded to a Participant shall
immediately lapse and such Shares shall thereafter be immediately transferable
and nonforfeitable.

ARTICLE 8.        PERFORMANCE UNITS

         8.1 Grant of Performance Units. The Board may, from time to time and
upon such terms and conditions as it may determine, grant Performance Units
which will become payable to a Participant upon certification in writing by the
Board that the Performance Goals related thereto have been achieved.

         8.2 Performance Unit Agreement. Each Performance Unit grant shall be
evidenced by a Performance Unit Agreement that shall specify the Performance
Goals, the Performance Period and the number of Performance Units to which it
pertains.

         8.3 Performance Period. The period of performance ("Performance
Period") with respect to each Performance Unit shall be such period of time,
which shall not be less than one year, nor more than five years, as determined
by the Board, for the measurement of the extent to which Performance Goals are
attained.

         8.4 Performance Goals. The goals ("Performance Goals") that are to be
achieved with respect to each Performance Unit, or Restricted Stock subject to a
requirement that Performance Goals be achieved, shall be those objectives
established by the Board as it deems appropriate, and which may be expressed in
terms of, by way of illustration and not limitation, (a) earnings per Share, (b)
Share price, (c) pre-tax profit, (d) net earnings, (e) return on equity or
assets, (f) revenues or (g) any combination of the foregoing Performance Goals,
in respect of the performance of the Company and its Subsidiaries (which may be
on a consolidated basis), a Subsidiary, a division or other operating unit of
the Company. Performance goals may be absolute or relative and may be expressed
in terms of a progression within a specified range. The Performance Goals with
respect to a Performance Period shall be established by the Board in order to
comply with Rule 16b-3 under the Exchange Act and section 162(m) of the Code, as
applicable.

         8.5 Termination of Employment. If the employment of a Participant shall
terminate prior to the expiration of the Performance Period for any reason other
than for death, Disability or Retirement, the Performance Units then held by the
Participant shall immediately terminate. In the case of termination of
employment by reason of death, Disability or Retirement of a Participant prior
to the expiration of the Performance Period, any then outstanding Performance
Units of such Participant shall be payable in an amount equal to the maximum
amount payable under the Performance Unit multiplied by a percentage equal to
the percentage that would have been earned under the terms of the Performance
Unit Agreement assuming that the rate at which the Performance Goals have been
achieved as of the date of such termination of employment would have continued
until the end of the Performance Period; provided,

                                      -13-
<PAGE>
 
however, that if no maximum amount payable is specified in the Performance
Unit Agreement, the amount payable shall be such amount as the Board shall
determine is reasonable.

         8.6 Payment Upon Change in Control. Upon a Change in Control, any then
outstanding Performance Units shall become fully vested and immediately payable
in an amount which is equal to the greater of (a) the maximum amount payable
under the Performance Unit multiplied by a percentage equal to the percentage
that would have been earned under the terms of the Performance Unit Agreement
assuming that the rate at which the Performance Goals have been achieved as of
the date of such Change in Control would have continued until the end of the
Performance Period or (b) the maximum amount payable under the Performance Unit
multiplied by the percentage of the Performance Period completed by the
Participant at the time of the Change in Control; provided, however, that if no
maximum amount payable is specified in the Performance Unit Agreement, the
amount payable shall be such amount as the Board shall determine is reasonable.

         8.7 Time and Manner of Payment of Performance Units. Subject to such
terms and conditions as the Board may impose, and unless otherwise provided in
the Performance Unit Agreement, Performance Units shall be payable within 90
days following the end of the Performance Period during which the Participant
attained at least the minimum acceptable level of achievement under the
Performance Goals, or 90 days following a Change in Control, as applicable. The
Board, in its discretion, may determine at the time of payment required in
connection with a Performance Unit whether such payment shall be made (a) solely
in cash, (b) solely in Shares (valued at the Fair Market Value of the Shares on
the date of payment) or (c) a combination of cash and Shares; provided, however,
that if a Performance Unit becomes payable upon a Change in Control, the
Performance Unit shall be paid solely in cash.

         8.8 Designation of Beneficiary. Each Participant may, from time to
time, name any beneficiary or beneficiaries (who may be named contingently or
successively) to whom the right to receive payments under a Performance Unit is
to be paid in case of the Participant's death before receiving any or all such
payments. Each such designation shall revoke all prior designations by the
Participant, shall be in a form prescribed by the Company and shall be effective
only when filed by the Participant in writing with the Board or its designee
during the Participant's lifetime. In the absence of any such designation,
benefits remaining unpaid at the Participant's death shall be paid to the
Participant's estate.

ARTICLE 9.        AMENDMENT, MODIFICATION AND TERMINATION

                                      -14-
<PAGE>
 
         9.1 Termination Date. The Plan shall terminate on the earliest to occur
of (a) the tenth anniversary of the adoption of the Plan by the Board, (b) the
date when all Shares available under the Plan shall have been acquired pursuant
to the exercise of Awards and the payment of all benefits in connection with
Performance Unit Award has been made or (c) such other date as the Board may
determine in accordance with Section 9.2.

         9.2 Amendment, Modification and Termination. The Board may, at any
time, amend, modify or terminate the Plan. Without the approval of the
shareholders of the Company (as may be required by section 162(m) of the Code,
Section 16 of the Exchange Act and the rules promulgated thereunder, any
national securities exchange or national market system on which the Shares are
then listed, included or reported or a regulatory body having jurisdiction with
respect hereto), however, no such amendment, modification or termination may:

                  9.2.1 materially increase the benefits accruing to
Participants under the Plan;

                  9.2.2 increase the total amount of Shares which may be issued

                  9.2.3 materially modify the class of Employees eligible to
participate in the Plan;

                  9.2.4    extend the term of the Plan; or

                  9.2.5 otherwise modify or add a material term of the Plan (as
determined under section 162(m) of the Code and Proposed Treasury Regulation
section 1.162-27).

         9.3 Awards Previously Granted. No amendment, modification or
termination of the Plan shall in any manner adversely affect any outstanding
Award without the written consent of the Participant holding such Award.

ARTICLE 10.       NON -TRANSFERABILITY

         A Participant's rights under the Plan may not be assigned, pledged or
otherwise transferred other than by will or the laws of descent and
distribution, except that upon a Participant's death, the Participant's rights
to payment pursuant to a Performance Unit may be transferred to a beneficiary
designated in accordance with the provisions of Section 8.8; provided,
however, that in the case of NQSOs, the Participant may, subject 

                                      -15-
<PAGE>
 
to any restriction under Section 16(b) of the Exchange Act, if applicable,
transfer the Options to the Participant's spouse, lineal descendants, trusts
for their benefit or a charitable remainder trust of which the Participant or
such family members referred to above are a beneficiary or beneficiaries.

ARTICLE 11.       NO GRANTING OF EMPLOYMENT RIGHTS

         Neither the Plan, nor any action taken under the Plan, shall be
construed as giving any Employee the right to become a Participant, nor shall an
Award under the Plan be construed as giving a Participant any right with respect
to continuance of employment by the Company or any of its Subsidiaries. The
Company expressly reserves the right to terminate, whether by dismissal,
discharge or otherwise, a Participant's employment at any time, with or without
Cause, except as may otherwise be provided by any written agreement between the
Company and the Participant.

ARTICLE 12.       WITHHOLDING

         12.1 Tax Withholding. A Participant shall remit to the Company an
amount sufficient to satisfy Federal, state and local taxes (including the
Participant's FICA and Medicare obligation) required by law to be then withheld
by the Company with respect to any grant, exercise or payment made under or as a
result of the Plan.

         12.2 Share Withholding. If the Company has a withholding obligation
upon the issuance of Shares under the Plan, a Participant may, subject to the
discretion of the Board, elect to satisfy the withholding requirement, in whole
or in part, by having the Company withhold Shares having a Fair Market Value on
the date the withholding tax is to be determined equal to the amount required to
be withheld under applicable law.

ARTICLE 13.       INDEMNIFICATION

         Except in relation to matters as to which the Board member was grossly
negligent or engaged in willful misconduct, no member of the Board shall be
personally liable for any action, determination or interpretation taken or made
with respect to the Plan, and all members of the Board shall, to the extent
permitted by law, be fully indemnified and protected by the Company with respect
to any such action, determination or interpretation.

ARTICLE 14.       SUCCESSORS

         All obligations of the Company with respect to Awards granted under the
Plan shall be binding on any successor to the Company, whether the existence of
such successor is a result of a direct or indirect purchase, merger,
consolidation or otherwise, of all or substantially all of the business and/or
assets of the Company.

ARTICLE 15.       GOVERNING LAW

         To the extent not preempted by Federal law, the Plan and all agreements
under the Plan, shall be governed by, and construed in accordance with, the laws
of the State of California without regard to its conflict of laws principles.

purchase stock of the Company.

         (b) The word "Affiliate" as used in the Plan means any parent
corporation or subsidiary corporation, as those terms are defined in Sections
424(e) and (f), respectively, of the Internal Revenue Code of 1986, as amended
(the "Code").

         (c) The Company, by means of the Plan, seeks to retain the services of
existing employees, to secure and retain the services of new employees, and to
provide incentives for such persons to exert maximum efforts for the success of
the Company and its designated Affiliates.

         (d) The Company intends that the rights to purchase stock of the
Company granted under the Plan be considered options issued under an "employee
stock purchase plan" as that term is defined in Section 423(b) of the Code.

2.       ADMINISTRATION.

         (a) The Plan shall be administered by the Board of Directors (the
"Board") of the Company unless and until the Board delegates administration to a
Committee, as provided in subparagraph 2(c). Whether or not the Board has
delegated administration, the Board shall have the final power to determine all
questions of policy and expediency that may arise in the administration of the
Plan.

         (b) The Board shall have the power, subject to, and within the
limitations of, the express provisions of the Plan:

                  (i) To determine when and how rights to purchase stock of the
Company shall be granted and the provisions of each offering of such rights
(which need not be identical).

                                      -1-
<PAGE>
 
                  (ii) To designate from time to time which Affiliates of the
Company shall be eligible to participate in the Plan.

                  (iii) To construe and interpret the Plan and rights granted
under it, and to establish, amend and revoke rules and regulations for its
administration. The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan, in a manner and to the extent it
shall deem necessary or expedient to make the Plan fully effective.

                  (iv) To amend the Plan as provided in paragraph 13.

                  (v) Generally, to exercise such powers and to perform such
acts as the Board deems necessary or expedient to promote the best interests of
the Company and its Affiliates and to carry out the intent that the Plan be
treated as an "employee stock purchase plan" within the meaning of Section 423
of the Code.

         (c) The Board may delegate administration of the Plan to a committee
comprised of two or more non-employee directors (the "Committee"), which may be
constituted in accordance with the applicable requirements of Rule 16b-3 under
the Securities Exchange Act of 1934 (the "Exchange Act" and "Rule 16b-3"). If
administration is delegated to a Committee, the Committee shall have, in
connection with the administration of the Plan, the powers theretofore possessed
by the Board, subject, however, to such resolutions, not inconsistent with the
provisions of the Plan, as may be adopted from time to time by the Board. The
Board may abolish the Committee at any time and revest in the Board the
administration of the Plan.

3.       SHARES SUBJECT TO THE PLAN.

         (a) Subject to the provisions of paragraph 12 relating to adjustments
upon changes in stock, the stock that may be sold pursuant to rights granted
under the Plan shall not exceed in the aggregate Two Hundred Thousand (200,000)
shares of the Company's common stock (the "Common Stock"). If any right granted
under the Plan shall for any reason terminate without having been exercised, the
Common Stock not purchased under such right shall again become available for the
Plan.

         (b) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.

4.       GRANT OF RIGHTS; OFFERING.

         The Board or the Committee may from time to time grant or provide for
the grant of rights to purchase Common Stock of the Company under the Plan to
eligible employees 

                                      -2-
<PAGE>
 
(an "Offering") on a date or dates (the "Offering Date(s)") selected by the
Board or the Committee. Each Offering shall be in such form and shall contain
such terms and conditions as the Board or the Committee shall deem
appropriate, which shall comply with the requirements of Section 423(b)(5) of
the Code that all employees granted rights to purchase stock under the Plan
shall have the same rights and privileges. The terms and conditions of an
Offering shall be incorporated by reference into the Plan and treated as part
of the Plan. The provisions of separate Offerings need not be identical, but
each Offering shall include (through incorporation of the provisions of this
Plan by reference in the document comprising the Offering or otherwise) the
period during which the Offering shall be effective, which period shall not
exceed twenty-seven (27) months beginning with the Offering Date, and the
substance of the provisions contained in paragraphs 5 through 8, inclusive.

5.       ELIGIBILITY.

         (a) Rights may be granted only to employees of the Company or, as the
Board or the Committee may designate as provided in subparagraph 2(b), to
employees of any Affiliate of the Company. Except as provided in subparagraph
5(b), an employee of the Company or any such Affiliate shall not be eligible to
be granted rights under the Plan, unless, on the applicable Offering Date, such
employee has been in the employ of the Company or any such Affiliate for such
continuous period preceding such grant as the Board or the Committee may
require, but in no event shall the required period of continuous employment be
equal to or greater than two (2) years. In addition, unless otherwise determined
by the Board or the Committee and set forth in the terms of the applicable
Offering, no employee of the Company or any such Affiliate shall be eligible to
be granted rights under the Plan, unless, on the applicable Offering Date, such
employee's customary employment with the Company or such Affiliate is for at
least twenty (20) hours per week and at least five (5) months per calendar year.

         (b) The Board or the Committee may provide that each person who, during
the course of an Offering, first becomes an eligible employee of the Company or
designated Affiliate of the Company will, on a date or dates specified during
the Offering which coincides with the day on which such person becomes an
eligible employee or occurs thereafter, receive a right under that Offering,
which right shall thereafter be deemed to be a part of that Offering. Such right
shall have the same characteristics as any rights originally granted under that
Offering, as described herein, except that:

                  (i) the date on which such right is granted shall be the
"Offering Date" of such right for all purposes, including determination of the
exercise price of such right;

                  (ii) the period of the Offering with respect to such right
shall begin on its Offering Date and end coincident with the end of such
Offering; and

                                      -3-
<PAGE>
 
                  (iii) the Board or the Committee may provide that if such
person first becomes an eligible employee within a specified period of time
before the end of the Offering, he or she will not receive any right under that
Offering.

         (c) No employee shall be eligible for the grant of any rights under the
Plan if. immediately after any such rights are granted, such employee owns stock
possessing five percent (5%) or more of the total combined voting power or value
of all classes of stock of the Company or of any Affiliate. For purposes of this
subparagraph 5(c), the rules of Section 424(d) of the Code shall apply in
determining the stock ownership of any employee, and stock which such employee
may purchase under all outstanding rights and options shall be treated as stock
owned by such employee.

         (d) An eligible employee may be granted rights under the Plan only if
such rights, together with any other rights granted under "employee stock
purchase plans" of the Company and any Affiliates, as specified by Section
423(b)(8) of the Code, do not permit such employee's rights to purchase stock of
the Company or any Affiliate to accrue at a rate which exceeds Twenty-Five
Thousand Dollars ($25,000) of fair market value of such stock (determined at the
time such rights are granted) for each calendar year in which such rights are
outstanding at any time.

         (e) Officers of the Company and any designated Affiliate shall be
eligible to participate in Offerings under the Plan, provided, however, that the
Board may provide in an Offering that certain employees who are highly
compensated employees within the meaning of Section 423(b)(4)(D) of the Code
shall not be eligible to participate.

6.       RIGHTS; PURCHASE PRICE.

         (a) On each Offering Date, each eligible employee, pursuant to an
Offering made under the Plan, shall be granted the right to purchase up to the
number of shares of Common Stock of the Company purchasable with a percentage,
to be designated by the Board or the Committee and not exceeding fifteen percent
(15%), of such employee's "earnings" (as defined by the Board or the Committee
in each Offering) during the period which begins on the Offering Date (or such
later date as the Board or the Committee determines for a particular Offering)
and ends on the date stated in the Offering, which date shall be no later than
the end of the Offering. The Board or the Committee shall establish one or more
dates during an Offering (the "Purchase Date(s)") on which rights granted under
the Plan shall be exercised and purchases of Common Stock carried out in
accordance with such Offering.

         (b) In connection with each Offering made under the Plan, the Board or
the Committee may specify a maximum number of shares that may be purchased by
any employee as well as a maximum aggregate number of shares that may be
purchased by all 

                                      -4-
<PAGE>
 
eligible employees pursuant to such Offering. In addition, in connection with
each Offering that contains more than one Purchase Date, the Board or the
Committee may specify a maximum aggregate number of shares which may be
purchased by all eligible employees on any given Purchase Date under the
Offering. If the aggregate purchase of shares upon exercise of rights granted
under the Offering would exceed any such maximum aggregate number, the Board
or the Committee shall make a pro rata allocation of the shares available in
as nearly a uniform manner as shall be practicable and as it shall deem to be
equitable.

         (c) The purchase price of stock acquired pursuant to rights granted
under the Plan shall be equal to the lesser of:

                  (i) an amount equal to eighty-five percent (85%) of the fair
market value of the stock on the Offering Date; or

                  (ii) an amount equal to eighty-five percent (85%) of the fair
market value of the stock on the Purchase Date.

7.       PARTICIPATION; WITHDRAWAL; TERMINATION.

         (a) An eligible employee may become a participant in the Plan pursuant
to an Offering by delivering a participation agreement to the Company within the
time specified in the Offering, in such form as the Company provides. Each such
agreement shall authorize payroll deductions of up to the maximum percentage
specified by the Board or the Committee of such employee's "earnings" during the
Offering (as defined by the Board or Committee in each Offering). The payroll
deductions made for each participant shall be credited to an account for such
participant under the Plan and shall be deposited with the general funds of the
Company. A participant may reduce (including to zero) or increase the amount of
such payroll deductions, and an eligible employee may begin such payroll
deductions after the beginning of any Offering only as provided for in the
Offering. A participant may make additional payments into his or her account
only if specifically provided for in the Offering and only if the participant
has not had the maximum amount withheld during the Offering.

         (b) At any time during an Offering, a participant may terminate his or
her payroll deductions under the Plan and withdraw from the Offering by
delivering to the Company a notice of withdrawal in such form as the Company
provides. Such withdrawal may be elected at any time prior to the end of the
Offering except as provided by the Board or the Committee in the Offering.
Upon such withdrawal from the Offering by a participant, the Company shall
distribute to such participant all of his or her accumulated payroll
deductions (reduced to the extent, if any, such deductions have been used to
acquire stock for the participant) under the Offering, without interest, and
such participant's withdrawal of such participant's interest in that Offering
will have no effect upon such participant's

                                      -5-
<PAGE>
 
eligibility to participate in any other Offerings under the Plan but such
participant will be required to deliver a new participation agreement in order
to participate in subsequent Offerings under the Plan.

         (c) Rights granted pursuant to any Offering under the Plan shall
terminate immediately upon cessation of any participating employee's employment
with the Company and any designated Affiliate, for any reason, and the Company
shall distribute to such terminated employee all of his or her accumulated
payroll deductions (reduced to the extent, if any, such deductions have been
used to acquire stock for the terminated employee) under the Offering, without
interest.

         (d) Rights granted under the Plan shall not be transferable by a
participant otherwise than by will or the laws of descent and distribution, or
by a beneficiary designation as provided in paragraph 14 and, otherwise during
his or her lifetime, shall be exercisable only by the person to whom such rights
are granted.

8.       EXERCISE.

         (a) On each Purchase Date specified therefor in the relevant Offering,
each participant's accumulated payroll deductions and other additional payments
specifically provided for in the Offering (without any increase for interest)
will be applied to the purchase of whole shares of stock of the Company, up to
the maximum number of shares permitted pursuant to the terms of the Plan and the
applicable Offering, at the purchase price provided for in paragraph 6(c). No
fractional shares shall be issued upon the exercise of rights granted under the
Plan. The amount, if any, of accumulated payroll deductions remaining in each
participant's account after the purchase of shares which is less than the amount
required to purchase whole share of stock on the final Purchase Date of an
Offering shall be distributed in full to the participant after such Purchase
Date, without interest.

         (b) No rights granted under the Plan may be exercised to any extent
unless the shares to be issued upon such exercise under the Plan (including, to
the extent required by applicable law, rights granted thereunder) are covered by
an effective registration statement pursuant to the Securities Act of 1933, as
amended (the "Securities Act"), and the Plan is in material compliance with all
applicable state, foreign and other securities and other laws applicable to the
Plan. If on a Purchase Date in any Offering hereunder the shares to be issued
are not so registered or the Plan is not in such compliance, no rights granted
under the Plan or any Offering shall be exercised on such Purchase Date, and the
Purchase Date shall be delayed until the Plan is subject to such an effective
registration statement and such compliance, except that the Purchase Date
shall not be delayed more than twelve (12) months and the Purchase Date shall
in no event be more than twenty-seven (27) months from the applicable Offering
Date. If on the Purchase Date of any Offering hereunder, as delayed to the
maximum extent permissible, the Plan is not registered and in such

                                      -6-
<PAGE>
 
compliance, no rights granted under the Plan or any Offering shall be
exercised and all payroll deductions accumulated during the Offering (reduced
to the extent, if any, such deductions have been used to acquire stock) shall
be distributed to the participants, without interest.

         (c) Directors and officers who fall within the definition of "officer"
under Rule 16a-1(f) promulgated under the Exchange Act shall deliver to the
Corporate Secretary of the Company an executed notice of his/her intention to
sell shares acquired upon exercise of rights granted hereunder. Such notice, in
which there is specified the number of shares which are to be sold and the date
such shares were acquired, shall be provided at least one full business day in
advance of the proposed date of sale.

9.       COVENANTS OF THE COMPANY.

         (a) During the term of the rights granted under the Plan, the Company
shall keep available at all times the number of shares of stock required to
satisfy such rights.

         (b) The Company shall seek to obtain from each federal, state, foreign
or other regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to issue and sell shares of stock upon exercise of
the rights granted under the Plan. If, after reasonable efforts, the Company is
unable to obtain from any such regulatory commission or agency the authority
which counsel for the Company deems necessary for the lawful issuance and sale
of stock under the Plan, the Company shall be relieved from any liability for
failure to issue and sell stock upon exercise of such rights unless and until
such authority is obtained.

10.      USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of stock pursuant to rights granted under the
Plan shall constitute general funds of the Company.

11.      RIGHTS  AS A STOCKHOLDER.

         A participant shall not be deemed to be the holder of, or to have any
of the rights of, a holder with respect to, any shares subject to rights granted
under the Plan unless and until the participant's shareholdings acquired upon
exercise of rights under the Plan are recorded in the books of the Company.

12.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (a) If any change is made in the stock subject to the Plan or any
rights granted under the Plan (through merger, consolidation, reorganization,
recapitalization, 

                                      -7-
<PAGE>
 
reincorporation, stock dividend, dividend in property other than cash, stock
split, liquidation dividend, combination of shares, exchange of shares, change
in corporate structure or other fundamental corporate transaction not
involving the receipt of consideration by the Company), the Plan and
outstanding rights will be appropriately adjusted as to the class(es) and
maximum number of shares subject to the Plan and the class(es) and number of
shares, and price per share of stock, subject to outstanding rights. Such
adjustments shall be made by the Board or the Committee, the determination of
which shall be final, binding and conclusive for all purposes.

         (b) In the event of: (1) a dissolution or liquidation of the Company;
(2) a merger or consolidation in which the Company is not the surviving
corporation; (3) a reverse merger in which the Company is the surviving
corporation but the shares of the Company's Common Stock outstanding immediately
preceding the merger are converted by virtue of the merger into other property,
whether in the form of securities, cash or otherwise; or (4) the acquisition by
any person, entity or group within the meaning of Section 13(d) or 14(d) of the
Exchange Act or any comparable successor provisions (excluding any employee
benefit plan, or related trust, sponsored or maintained by the Company or any
Affiliate of the Company) of the beneficial ownership (within the meaning of
Rule 13d-3 promulgated under the Exchange Act, or comparable successor rule) of
securities of the Company representing at least fifty percent (50%) of the
combined voting power entitled to vote in the election of directors, then, as
determined by the Board in its sole discretion (i) any surviving or acquiring
corporation may assume outstanding rights or substitute similar rights for those
under the Plan, (ii) such rights may continue in full force and effect, or (iii)
participants' accumulated payroll deductions may be used to purchase Common
Stock immediately prior to the transaction described above and the participants'
rights under the ongoing Offering terminated.

13.      AMENDMENT OF THE PLAN.

         (a) The Board at any time, and from time to time, may amend the Plan.
However, except as provided in paragraph 12 relating to adjustments upon changes
in stock, no amendment shall be effective unless approved by the shareholders of
the Company within twelve (12) months before or after the adoption of the
amendment by the Board, where the amendment will:

                  (i) Increase the number of shares reserved for rights under
the Plan;

                  (ii) Modify the provisions as to eligibility for participation
in the Plan (to the extent such modification requires shareholder approval in
order for the Plan to obtain employee stock purchase plan treatment under
Section 423 of the Code or to comply with the requirements of Rule 16b-3); or

                                      -8-
<PAGE>
 
                  (iii) Modify the Plan in any other way if such modification
requires shareholder approval in order for the Plan to obtain employee stock
purchase plan treatment under Section 423 of the Code or to comply with the
requirements of Rule 16b-3 or Section 162(m) of the Code.

It is expressly contemplated that the Board shall take all action it deems
necessary or advisable to provide eligible employees with the maximum benefits
provided or to be provided under the provisions of the Code and the regulations
promulgated thereunder relating to employee stock purchase plans and/or to bring
the Plan and/or rights granted under it into compliance therewith.

         (b) Rights and obligations under any rights granted before amendment of
the Plan shall not be impaired by any amendment of the Plan, except with the
consent of the person to whom such rights were granted, or except as necessary
to comply with any laws or governmental regulations, or except as necessary to
ensure that the Plan and/or rights granted under the Plan comply with the
requirement of Section 423 of the Code.

14.      DESIGNATION OF BENEFICIARY.

         (a) A participant may file with the Company's secretary a written
designation of a beneficiary who is to receive any shares and cash, if any, from
the participant's account under the Plan in the event of such participant's
death during, or subsequent to the end of, an Offering but prior to delivery to
the participant of such shares and cash.

         (b) Such designation of beneficiary may be changed by the participant
at any time by written notice filed with the Company's secretary. In the event
of the death of a participant and in the absence of a beneficiary validly
designated under the Plan who is living at the time of such participant's death,
the Company shall deliver such shares and/or cash to the executor or
administrator of the estate of the participant, or if no such executor or
administrator has been appointed (to the knowledge of the Company), the Company,
in its sole discretion, may deliver such shares and/or cash to the spouse or to
any one or more dependents or relatives of the participant, or if no spouse,
dependent or relative is known to the Company, then to such other person as the
Company may designate.

15.      TERMINATION OR SUSPENSION OF THE PLAN.

in effect shall not be impaired by suspension or termination of the Plan, except
as expressly provided 

                                      -9-

in the Plan or with the consent of the person to whom such rights were

regulation, or except as necessary to ensure that the Plan and/or rights
granted under the Plan comply with the requirements of Section 423 of the
Code.

16.      EFFECTIVE DATE OF PLAN.

be prior to the Effective Date.

                              STOCK OPTION PLAN



ARTICLE 1.  PURPOSE

         The purpose of this 1998 Non-Employee Directors Stock Option Plan is to
promote the interests of ATG Inc., its subsidiaries and shareholders, by having
non-employee directors of the Company acquire a proprietary interest in the
Company. Such investments should increase the personal interest and the special
effort of such persons in providing for the continued success and progress of
the business of the Company and should enhance the Company's efforts to attract
and retain competent non-employee directors.

ARTICLE 2.  DEFINITIONS AND CONSTRUCTION

         1 Definitions. As used in the Plan, terms defined parenthetically
immediately after their use or otherwise herein shall have the respective
meanings provided by such definitions, and the terms set forth below shall have
the following meanings (in either case, such terms shall apply equally to both
the singular and plural forms of the terms defined):

           (a) "Board" shall mean the Board of Directors of the Company.

           (b) "Cause" shall mean, unless otherwise defined in an Option
Agreement, a felony conviction of a Non-Employee Director or the failure of a
Non-Employee Director to contest prosecution for a felony, or a Non-Employee
Director's willful misconduct, gross negligence or dishonesty or the
Non-Employee Director's breach of his or her fiduciary duty to the Company or
its shareholders, any of which is determined by the Board to be directly and
materially harmful to the business or reputation of the Company or its
Subsidiaries.

           (c) "Change in Control" shall mean any of the following
events:

                (1)     An acquisition (other than directly from the Company)
of any voting securities of the Company ("Voting Securities") by any Person
immediately after which such Person has Beneficial Ownership (within the meaning
of Rule 13d-3 promulgated under the Exchange Act) of 30% or more of the combined
voting power of the Company's then outstanding Voting Securities; provided,
however, that in 

                                       1
<PAGE>
 
determining whether a Change in Control has occurred, Voting Securities which
are acquired in a Non-Control Acquisition (as hereinafter defined) shall not
constitute an acquisition which would cause a Change in Control. A Non-Control
Acquisition shall mean an acquisition by (i) the Company or any Subsidiary,
(ii) an employee benefit plan (or a trust forming a part thereof) maintained
by the Company or any Subsidiary or (iii) any Person in connection with a Non-
Control Transaction (as hereinafter defined);

                (2)     The individuals who, as of the Effective Date, are
members of the Board ("Incumbent Board") cease for any reason to constitute at
least a majority of the Board; provided, however, that if the election, or
nomination for election by the Company's shareholders, of any new director was
approved by a vote of at least a majority of the Incumbent Board, such new
director shall, for purposes of the Plan, be considered as a member of the
Incumbent Board; provided, further, however, that no individual shall be
considered a member of the Incumbent Board if such individual initially assumed
office as a result of either an actual or threatened election contest (as
described in Rule 14a-11 promulgated under the Exchange Act) or other actual or
threatened solicitation of proxies or consents by or on behalf of a Person other
than the Board ("Proxy Contest") including by reason of any agreement intended
to avoid or settle any such election contest or Proxy Contest; or

                (3)     Approval by shareholders of the Company of:

                        (A)      A merger, consolidation or reorganization
involving the Company, unless such is a Non-Control Transaction. For purposes of
the Plan, the term "Non-Control Transaction" shall mean a merger, consolidation
or reorganization of the Company in which:

                                  (i)  the shareholders of the Company
immediately before such merger, consolidation or reorganization, own, directly
or indirectly immediately following such merger, consolidation or

Board immediately prior to the execution of the agreement providing for such

lifetime only by the Optionee; provided, however, that the Optionee may
transfer the Options to the Optionee's spouse, lineal descendants, trusts for

such times and places as it determines and may meet through telephone conference
call. A majority of its members shall constitute a quorum, and the decision of
the majority of those present at any meeting at which a quorum is present shall
constitute the decision of the Board. Any decision reduced to writing and signed
by a majority of the members of the Board shall be fully effective as if it had

and selections made by the Board pursuant to the provisions of the Plan shall be
final. To the extent required by law and Rule 16b-3 promulgated under the

administration shall be deemed null and void, and in all events the Plan shall
be construed in favor of its meeting the requirements of Rule 16b-3 promulgated
under the Exchange Act. Each Optionee shall deliver to the Corporate Secretary
of the Company an executed notice of his/her intention to sell Shares acquired

that the Company merges or consolidates with another corporation, or all or
substantially all of the Company's capital stock or assets are acquired by
another corporation, and the surviving or acquiring corporation issues shares of
its stock to the Company's shareholders in connection with the merger,
consolidation or acquisition, the surviving or acquiring corporation shall adopt
the Plan and upon the exercise of an Option, the Optionee shall, at no
additional cost (other the Option Price), be entitled to receive, in lieu of the
number of Shares with respect to which such Option is then exercisable, the
number and class of stock or other securities to which the Optionee would have
been entitled pursuant to the terms of the merger, consolidation or acquisition
if immediately prior thereto the Optionee had been the holder of record of a
number of Shares equal to the number of Shares as to which the Option shall then
be exercisable.

                             REMEDIES ON DEFAULT

Upon the occurrence of any Event of Default, the Bank may, at its sole and
absolute election, without demand and only upon such notice as may be required
by law:

11.1 Acceleration: Declare any or all of the Borrower's indebtedness Owing to
the Bank, whether under this Agreement or any other document, instrument or
agreement, immediately due and payable, whether or not otherwise due and
payable.

11.2 Letter of Credit Collateralization: Require Borrower to deposit with Bank
an amount equal to the then existing Letter of Credit Obligations.

11.3 Cease Extending Credit: Cease issuing Letter of Credit or otherwise
extending credit to or for the account of the Borrower under this Agreement or
under any other agreement now existing or hereafter entered into between the
Borrower and the Bank.

11.4 Termination: Terminate this Agreement as to any future obligation of the
Bank without affecting the Borrower's obligations to the Bank or the Bank's
rights and remedies under this Agreement or under any other document,
instrument or agreement.

11.5 Protection of Security Interest: Make such payments and do such acts as the
Bank, in its sole judgment, considers necessary and reasonable to protect its
security interest or lien in the Collateral. The Borrower hereby irrevocably
authorizes the Bank to pay, purchase, contest or compromise any encumbrance,
lien or claim which the Bank, in its sole judgment, deems to be prior or
superior to its security interest. Further, the Borrower hereby agrees to pay to
the Bank, upon demand therefor, all expenses and expenditures (including
attorneys' fees) incurred in connection with the foregoing.

11.6 Foreclosure: Enforce any security interest or lien given or provided for
under this Agreement or under any security agreement, mortgage, deed of trust or
other document, in such manner and such order, as to all or any part of the
properties subject to such security interest or lien, as the Bank, in its sole
judgment, deems to be necessary or appropriate and the Borrower hereby waives
any and all rights, obligations or defenses now or hereafter established by law
relating to the foregoing. In the enforcement of its security interest or lien,
the Bank is authorized to enter upon the premises where any Collateral is
located and take possession of the Collateral or any part thereof, together with
the Borrower's records pertaining thereto, or the Bank may require the Borrower
to assemble the Collateral and records pertaining thereto and make such
Collateral and records available to the Bank (including a copy of the Borrower's
customer lists) at a place designated by the Bank. The Bank may sell the
Collateral or any portions thereof, together with all additions, accessions and
accessories thereto, giving only such notices and following only such procedures
as are required by law, at either a public or private sale, or both, with or
without having the Collateral present at the time of the sale, which sale shall
be on such terms and conditions and conducted in such manner as the Bank
determines in its sole judgment to be commercially reasonable. Any deficiency
which exists after the disposition or liquidation of the Collateral shall be a
continuing liability of the Borrower to the Bank and shall be immediately paid
by the Borrower to the Bank.

11.7 Non-Exclusivity of Remedies: Exercise one or more of the Bank's rights set
forth herein or seek such other rights or pursue such other remedies as may be
provided by law, in equity or in any other agreement now existing or hereafter
entered into between the Borrower and the Bank, or otherwise.

11.8 Application of Proceeds: All amounts received by the Bank as proceeds from
the disposition or liquidation of the Collateral shall be applied to the
Borrower's indebtedness to the Bank as follows: first, to the costs and
expenses of collection, enforcement, protection and preservation of the Bank's
lien in the Collateral,

                                       11
<PAGE>
 
including court costs and reasonable attorneys' fees, whether or not suit is
commenced by the Bank; next, to those costs and expenses incurred by the Bank
in protecting, preserving, enforcing, collecting, liquidating, selling or
disposing of the Collateral; next, to the payment of accrued and unpaid
interest on all of the Obligations; next, to the payment of the outstanding
principal balance of the Obligations; and last, to the payment of any other
indebtedness owed by the Borrower to the Bank. Any excess Collateral or excess
proceeds existing after the disposition or liquidation of the Collateral and
after the expiration of all outstanding Letters of Credit will be returned or
paid by the Bank to the Borrower.

                                 SECTION 12
                                MISCELLANEOUS

12.1 Amounts Payable on Demand: If the Borrower shall fall to pay on demand any
amount so payable under this Agreement (including but not limited to interest),
the Bank may, at its option and without any obligation to do so and without
waiving any default occasioned by the Borrower having so failed to pay such
amount, create an Advance under the Line of Credit in an amount equal to the
amount so payable, which Advance shall thereafter bear interest as provided
under the Line of Credit.

12.2 Reliance: Each warranty, representation, covenant, obligation and agreement
contained in this Agreement shall be conclusively presumed to have been relied
upon by the Bank regardless of any investigation made or information possessed
by the Bank and shall be cumulative and in addition to any other warranties,
representations, covenants and agreements which the Borrower now or hereafter
shall give, or cause to be given, to the Bank.

12.3 Attorneys' Fees: In the event of any dispute or legal action in relation to
this Agreement or any document, instrument or agreement executed with respect
to, evidencing or securing the Obligations, Borrower, in the case of a dispute,
or the prevailing party, in the case of a legal action, shall, in addition to
all other sums to which it may be entitled, be entitled to reasonable attorneys'
fees.

12.4 Notices: All notices, payments, requests, information and demands which
either party hereto may desire, or may be required to give or make to the other
party hereto, shall be given or made to such party by hand delivery or through

                    [LETTERHEAD OF SANWA BANK APPEARS HERE]


                             CONTINUING GUARANTY


For value received and in consideration of the extension of credit by SANWA BANK
CALIFORNIA (the "Bank") to ATG INC. (the "Debtor") or the benefits to the
undersigned (the "Guarantor"), guaranties and promises to pay to the Bank any
and all Indebtedness (as defined below) and agrees as follows:

1. Indebtedness. The term "Indebtedness" is used herein in its most
comprehensive sense and includes any and all advances, debts, obligations,
guaranties and liabilities of the Debtor heretofore, now, or hereafter made,
incurred or created, whether voluntary or involuntary and however arising,
whether direct or acquired by the Bank by assignment or succession, whether due
or not due, absolute or contingent, liquidated or unliquidated, determined or
undetermined, and whether the Debtor may be liable individually or jointly with
others, or whether recovery upon any Indebtedness may be or hereafter becomes
barred by any statute of limitations or whether any Indebtedness may be or
hereafter becomes otherwise unenforceable.

2. Guaranty. The Guarantor unconditionally agrees to pay to the Bank or its
order, on demand, an amount equal to the amount of the Indebtedness or otherwise
perform any obligation of the Debtor undertaken pursuant to any Indebtedness. In
addition to any maximum principal liability hereunder, the Guarantor agrees to
(i) bear the expenses enumerated hereunder in the paragraph herein entitled
"Attorneys' Fees" and (ii) pay interest on the Indebtedness at the rate(s)
applicable thereto. Notwithstanding the foregoing, the Bank may allow the
Indebtedness to exceed the Guarantor's liability hereunder. Any payment by the
Guarantor shall not reduce the maximum principal obligation of the Guarantor
hereunder unless written notice to that effect is actually received by the Bank
at or prior to the time of such payment. Any payment by the Debtor or any other
person shall not reduce the Guarantor's maximum principal liability hereunder.

3. Right to Amend or Modify Indebtedness. The Guarantor authorizes the Bank, at
its sole discretion, with or without notice and without affecting the
Guarantor's liability hereunder, from time to time to: (i) change the time or
manner of payment, or any Indebtedness by renewal, extension, modification,
acceleration or otherwise; (ii) alter or change any provision of any
Indebtedness including, but not limited to, the rate of interest thereon, and
any document, instrument or agreement (other than this Guaranty), evidencing,
guaranteeing, securing or related to any Indebtedness; (iii) release, discharge,
exonerate, substitute or add one or more parties liable on any Indebtedness or
one or more endorsers, cosigners or guarantors for any Indebtedness; (iv) obtain
collateral for the payment of any Indebtedness or any guaranty thereof; (v)
release existing or after-acquired collateral on such terms as the Bank, in its
sole discretion, shall determine; (vi) apply any sums received from the Debtor,
any endorser, cosigner, other guarantor or other person liable on any
Indebtedness or from the sale or collection of collateral or its proceeds to
any indebtedness whatsoever owed or to be owed to the Bank by the Debtor in
any order or amount and regardless of whether or not such indebtedness is
guaranteed hereby, is secured by collateral or its due and payable; and (vii)
apply to any Indebtedness, in any order or amount, regardless of whether such
Indebtedness is secured by collateral or is due and payable, any sums received
from the Guarantor or from the sale of collateral in which the Guarantor has
granted the Bank a security interest.

4. Waivers. The Guarantor hereby unconditionally and irrevocably acknowledges
and agrees to the matters set froth below:

         A. Deficiency. In the event that any Indebtedness is now or hereafter
         secured by a deed of trust, the Guarantor waives any defense and all
         rights and benefits of those laws purporting to state that no
         deficiency judgment may be recovered on certain real property purchase
         money obligations (as presently contained in Section 580b of the
         California Code of Civil Procedure and as it may be amended or
         superseded in the future) and those laws purporting to state that no
         deficiency judgment may be received after a trustee's sale under a deed
         of trust (as presently contained in Section 580d of the California Code
         of Civil Procedure and as it may be amended or superseded in the
         future). THE GUARANTOR ACKNOWLEDGES THAT A FORECLOSURE BY A TRUSTEE'S
         SALE UNDER A DEED OF TRUST MAY RESULT IN THE DESTRUCTION OF THE
         GUARANTOR'S SUBROGATION RIGHTS THAT MAY OTHERWISE EXIST AND THAT A
         DESTRUCTION OF THOSE RIGHTS MAY CREATE A DEFENSE TO A DEFICIENCY
         JUDGMENT. THE GUARANTOR HEREBY SPECIFICALLY WAIVES ANY SUCH DEFENSE.

         B. Election of Remedies. The Guarantor waives any defense based upon
         the Guarantor's loss of a right against the Debtor arising from the
         Bank's election of a remedy on any Indebtedness under bankruptcy or
         other debtor relief laws or under any other laws, including, but not
         limited to, those purporting to reduce the Bank's right against the
         Guarantor in proportion to the principal obligation of any Indebtedness
         (as presently continued in Section 2809 of the California Civil Code
         and as it may be amended or superseded in the future).

         C. Statute of Limitations. The Guarantor waives the benefit of the
         statute of limitations affecting the Guarantor's liability hereunder
         or the enforcement hereof.

         D. Action Against the Debtor and Collateral (and Other Remedies). The
         Guarantor waives all right to require the Bank to: (i) proceed against
         the Debtor, any endorser, cosigner, other guarantor or other person
         liable on any Indebtedness; (ii) join the Debtor or any endorser,
         cosigner, other guarantor or other person liable on any Indebtedness in
         any action or actions that may be brought and prosecuted by the Bank
         solely and separately against the Guarantor on any Indebtedness; (iii)
         proceed against any item or items of collateral securing any
         Indebtedness or any guaranty thereof; or (iv) pursue or refrain from
         pursuing any other remedy whatsoever in the Bank's power.

         E. Debtor's Defense. The Guarantor waives any defense arising by reason
         of any disability or other defense of the Debtor, the Debtor's
         successor or any endorser, cosigner, other guarantor or other person
         liable on any Indebtedness. Until all Indebtedness has been paid in
         full, even though it may be in excess of the liability incurred hereby,
         the Guarantor shall not have any right of subrogation and the Guarantor
         waives any benefit of and right to participate in any collateral now or
         hereafter held by the Bank. The Guarantor waives all presentments,
         demands for performance, notices of nonperformance, protests, notices
         of protest, notices of dishonor, notices of sale of any collateral
         securing any Indebtedness or any guaranty thereof, and notice of the
         existence, creation or incurring of new or additional Indebtedness.

         F. Debtor's Financial Condition. The Guarantor hereby recognizes,
         acknowledges and agrees that advances may be made in the future from
         time to time with respect to any Indebtedness without authorization
         from or notice to the Guarantor even though the financial condition of
         the Debtor, any endorser, cosigner, other guarantor or other person
         liable on any Indebtedness may have deteriorated since the date of this
         Guaranty. The Guarantor waives all right to require the Bank to
         disclose any information with respect to: (i) any Indebtedness now
         existing or hereafter incurred; (ii) the present or future financial
         condition, credit or character of the Debtor, any endorser, cosigner,
         other guarantor or other person liable on any Indebtedness; (iii) any
         present or future 

                                      (1)
<PAGE>
 
         collateral securing any Indebtedness or any guaranty thereof; or (iv)
         any present or future action or inaction on the part of the Bank, the
         Debtor or any endorser, cosigner, other guarantor or other person
         liable on any Indebtedness. The Guarantor hereby assumes the
         responsibility for being informed of the financial condition, credit
         and character of the Debtor and of all circumstances bearing upon the
         risk of non-payment of any Indebtedness which diligent inquiry would
         reveal.

5. Right of Set-off; Grant of Security Interest. In addition to all liens upon
and rights of set-off against any monies, securities or other property of the
Guarantor given to the Bank by law, the Bank shall have a security interest in
and a right to set off against all monies, securities and other property of
the Guarantor now or hereafter in the possession of or on deposit with the
Bank, the Bank's agents or any one or more of them, whether held in general or
special account or deposit or for safekeeping or otherwise; and each such
security interest and right to set-off may be exercised without demand upon or
notice to the Guarantor. No action or inaction by the Bank with respect to any
security interest or right of set-off shall be deemed a waiver thereof and
every right of set-off and security interest shall continue in full force and
effect until specifically released by the Bank in writing. The security
interest created hereby shall secure all of the Guarantor's obligations under
this Guaranty.

6. Right of Foreclosure. The Bank may foreclose, either by judicial foreclosure
or by exercise of power of sale, any deed of trust securing any Indebtedness
even though such foreclosure may destroy or diminish the Guarantor's rights
against the Debtor. The Guarantor shall be liable to the Bank for any part of
any Indebtedness remaining unpaid after any such foreclosure whether or not such
foreclosure was for fair market value.

7. Subordination. Any indebtedness of the Debtor or any endorser, cosigner,
other guarantor or other person liable on any Indebtedness now or hereafter owed
to the Guarantor is hereby subordinated to the Indebtedness. Such indebtedness
owed to the Guarantor shall, if the Bank so requests, be collected, enforced and
received by the Guarantor as trustee for the Bank and be paid over to the Bank
on account of the Indebtedness but without reducing or affecting in any manner
the liability of the Guarantor set forth herein. Should the Guarantor fail to
collect the proceeds of any such indebtedness owed to it and pay the proceeds to
the Bank, the Bank, as the Guarantor's attorney-in-fact, may do such acts and
sign such documents in the Guarantor's name as the Bank considers necessary to
effect such collection.

8. Invalid, Fraudulent or Preferential Payments. The Guarantor agrees that, to
the extent the Debtor or any endorser, cosigner, other guarantor or other person
liable on any Indebtedness makes a payment or payments to, or is credited for
any payment or payments made for or on behalf of the Debtor to the Bank, which
payment or payments, or any part thereof, is subsequently invalidated,
determined to be fraudulent or preferential, set aside or required to be repaid
to any trustee, receiver, assignee or any other party whether under any
bankruptcy, state or federal law or under any common law or equitable cause or
otherwise, then, to the extent thereof, the obligation or part thereof intended
to be satisfied thereby shall be revived, reinstated and continued in full force
and effect as if such payment or payments had not originally been made or
credited.

9. Joint and Several Obligations; Independent Obligations. If more than one
Guarantor signs this Guaranty, the obligations hereunder are joint and several.
The Guarantor's obligations hereunder are independent of the obligations of the
Debtor or any endorser, cosigner, other guarantor or other person liable on any
Indebtedness and a separate action or actions may be brought and prosecuted
against the Guarantor on any Indebtedness.

10. Financial Information. The Guarantor hereby agrees to deliver or cause to be
delivered to the Bank:

         A. Other Information. (i) Financial Statements. Not later than April
         1st of each year, a copy of the personal financial statement of the

         federal income tax returns filed for each year.

11. Acknowledgment of Receipt. Receipt of a true copy of this Guaranty is hereby
acknowledged by the Guarantor. The Guarantor understands and agrees that this
Guaranty shall not constitute a commitment of any nature whatsoever by the Bank
to renew or hereafter extend credit to the Debtor. The Guarantor agrees that
this Guaranty shall be effective with or without notice from the Bank of the
Bank's acceptance hereof.

12. Continuing Guaranty. This Guaranty is a continuing guaranty. Revocation
shall be effective only upon written notice personally received by an officer of
the Bank at the originating office indicated below or actually received at the
originating office by United States mail postage prepaid. Notice shall be
effective at any office of the Bank should the originating office no longer be
in existence. Revocation shall be effective at the close of the Bank's business
day when such notice is actually received. Any revocation shall be effective
only as to the revoking party and shall not affect that party's obligation with
respect to any Indebtedness existing before such revocation is effective.

13. Non-Reliance. In executing this Guaranty, the undersigned is not relying,
and has not relied, upon any statement or representation made by the Bank, or
any employee, agent or representative of the Bank, with respect to the status,
financial condition or other matters related to the Debtor or the relationship
between the Debtor and the Bank.

14. Multiple Guaranties. If the Guarantor has executed or does execute more than
one guaranty of any indebtedness of the Debtor to the Bank, the limits of
liability thereunder and hereunder shall be cumulative.

15. Severability. Should any one or more provisions of this Guaranty be
determined to be illegal or unenforceable, all other provisions shall remain
effective.

16. Corporate or Partnership Authority. If the Debtor is a corporation or
partnership, the Bank need not inquire into the power of the Debtor or the
authority of its officers, directors, partners or agents acting or purporting to
act in its behalf and any credit granted in reliance upon the purported exercise
of such power or authority is guaranteed hereunder.

17. Separate Property. Any married person who signs this Guaranty expressly
agrees that recourse may be had against such person's separate property for all
obligations hereunder.

18. Assignment. The Bank may, with or without notice, assign this Guaranty in
whole or in part. This Guaranty shall inure to the benefit of the Bank, its
successors and assigns, and shall bind the Guarantor and the Guarantor's heirs,
executors, administrators, successors and assigns.

19. Waiver of Jury. The Guarantor and the Bank hereby expressly and voluntarily
waive any and all rights, whether arising under the California constitution, any
rules of the California Code of Civil Procedure, common law or otherwise, to
demand a trial by jury in any action, matter, claim, or cause of action
whatsoever arising out of or in any way related to this Guaranty or any other
agreement, document or transaction contemplated hereby.

20.      Dispute Resolution.

         A. Disputes. It is understood and agreed that, upon the request of any
         party to this Guaranty, any dispute, claim or controversy of any kind,
         whether in contract or in tort, statutory or common law, legal or
         equitable, now existing or hereinafter arising between the parties in
         any way arising out of, pertaining to or in connection with : (i) this
         Guaranty, or any related agreements, documents or instruments, (ii) all
         past and present loans, credits, accounts, deposit accounts (whether
         demand deposits or time deposits), safe deposit boxes, safekeeping
         agreements, guarantees, letters of credit, goods or services, or other
         transactions, contracts or agreements of any kind, (iii) any incidents,
         omissions, acts, practices, or occurrences causing injury to any party
         whereby another party or its agents, employees or representatives may
         be liable, in whole or in part, or (iv) any aspect of the past or
         present relationships of the parties, shall be resolved through a
         two-step dispute resolution process administered by the Judicial
         Arbitration & Medication Services, Inc. ("JAMS") as follows:

                                      (2)
<PAGE>
 
         B. Step I - Mediation. At the request of any party to the dispute,
         claim or controversy, the matter shall be referred to the nearest
         office of JAMS for mediation, which is an information, non-binding
         conference or conferences between the parties in which a referred judge
         or justice from the JAMS panel will seek to guide the parties to a
         resolution of the case.

         C. Step II - Arbitration (Contracts Not Secured By Real Property).
         Should any dispute, claim or controversy remain unresolved at the
         conclusion of the Step I Mediation Phase, then (subject to the
         restriction at the end of this subparagraph) all such remaining matters
         shall be resolved by final and binding arbitration before a different
         judicial panelist, unless the parties shall agree to have the mediator
         panelist act as arbitrator. The hearing shall be conducted at a
         location determined by the arbitration in Los Angeles, California (or
         such other city as may be agreed upon by the parties) and shall be
         administered by and in accordance with the then existing Rules of
         Practice and Procedure of JAMS and judgment upon any award rendered by
         the arbitrator may be entered by any State or Federal Court having
         jurisdiction thereof. The arbitrator shall determine which is the
         prevailing party and shall include in the award that party's reasonable
         attorneys' fees and costs. This subparagraph shall apply only if, at
         the time of the submission of the matter to JAMS, the dispute or issues
         involved do not arise out of any transaction which is secured by real
         property collateral or, if so secured, all parties consent to such
         submission.

         As soon as practicable after selection of the arbitrator, the
         arbitrator, or the arbitrator's designated representative, shall
         determine a reasonable estimate of anticipated fees and costs of the
         arbitrator, and render a statement to each party setting forth that
         party's pro-rata share of said fees and costs. Thereafter, each party
         shall, within 10 days of receipt of said statement, deposit said sum
         with the arbitrator. Failure of any party to make such a deposit shall
         result in a forfeiture by the non-deposing party of the right to
         prosecute or defend the claim which is the subject of the arbitration,
         but shall not otherwise serve to abate, stay or suspend the arbitration
         proceedings.

         D. Step II - Trial By Court Reference (Contracts Secured By Real
         Property). If the dispute, claim or controversy is not one required or
         agreed to be submitted to arbitration, as provided in the above
         subparagraph, and has not been resolved by Step I mediation, then any
         remaining dispute, claim or controversy shall be submitted for
         determination by a trial on Order of Reference conducted by a retired
         judge or justice from the panel of JAMS appointed pursuant to the
         provisions of Section 638(l) of the California Code of Civil Procedure,
         or any amendment, addition or successor section thereto, to hear the
         case and report a statement of decision thereon. The parties intend
         this general reference agreement to be specifically enforceable in
         accordance with said section. If the parties are unable to agree upon
         a member of the JAMS panel to act as referee, then one shall be
         appointed by the Presiding Judge of the county wherein the hearing is
         to be held. The parties shall pay in advance, to the referee, the
         estimated reasonable fees and costs of the reference, as may be
         specified in advance by the referee. The parties shall initially
         share equally, by paying their proportionate amount of the estimated
         fees and costs of the reference. Failure of any party to make such a
         fee deposit shall result in a forfeiture by the non-depositing party
         of the right to prosecute or defend any cause of action which is the
         subject of the reference, but shall not otherwise serve to abate,
         stay or suspend the reference proceeding.

         E. Provisional Remedies, Self Help and Foreclosure. No provision of, or
         the exercise of any rights under any portion of this Dispute Resolution
         provision, shall limit the right of any party to exercise self help
         remedies such as set off, foreclosure against any real or personal
         property collateral, or the obtaining of provisional or ancillary
         remedies, such as injunctive relief or the appointment of a receiver,
         from any court having jurisdiction before, during or after the pendency
         of any arbitration. At the Bank's option, foreclosure under a deed of
         trust or mortgage may be accomplished either by exercise of power of
         sale under the deed of trust or mortgage, or by judicial foreclosure.
         The institution and maintenance of an action for provisional remedies,
         pursuit of provisional or ancillary remedies or exercise of self help
         remedies shall not constitute a waiver of the right of any party to
         submit the controversy or claim to arbitration.

21. Attorneys' Fees. Whether or not any suit, action, arbitration or other
dispute resolution proceeding is instituted, the Guarantor agrees to pay
reasonable attorneys' fees and all other costs and expenses which may be
incurred in the collection of any indebtedness, in the protection or
preservation of, or realization on, any collateral securing any Indebtedness and
in the enforcement by the Bank of this Guaranty.

22. Governing Law. This Guaranty shall be governed by and construed according to
the laws of the State of California and the Guarantor hereby submits to the
jurisdiction of the courts of the State of California.

23. Entire Agreement. This Guaranty and all documents, instruments and
agreements mentioned herein constitute the entire and complete understanding of
the parties with respect to the transactions contemplated hereunder. All
previous conversations, memoranda and writings between the parties pertaining to
the transactions contemplated hereunder not incorporated or referenced in this
Guaranty or in such documents, instruments and agreements are superseded hereby.

24. Headings. The headings used herein are solely for the purpose of
identification and have no legal significance.

25. Address of the Bank. The Bank's originating office under this Guaranty is:
Oakland Main Office, 2127 Broadway, Oakland, CA 94612.

26. Maximum Principal Liability. THE MAXIMUM PRINCIPAL LIABILITY UNDER THIS
GUARANTY IS the amount of $8,000,000.00, plus interest at the rate(s) applicable
to any Indebtedness as set forth in the paragraph herein entitled "Guaranty" and
the expenses estimated in the paragraph herein entitled "Attorneys' Fees".

This Guaranty is made as of March 6, 1998, which shall be the date of this
Guaranty.

Executed by the undersigned Guarantor as of the date set forth above.

                                                                 EXHIBIT 10.34

                             CONTINUING GUARANTY


For value received and in consideration of the extension of credit by SANWA BANK
CALIFORNIA (the "Bank") to ATG INC. (the "Debtor") or the benefits to the
undersigned (the "Guarantor"), guaranties and promises to pay to the Bank any
and all Indebtedness (as defined below) and agrees as follows:

1. Indebtedness. The term "Indebtedness" is used herein in its most
comprehensive sense and includes any and all advances, debts, obligations,
guaranties and liabilities of the Debtor heretofore, now, or hereafter made,
incurred or created, whether voluntary or involuntary and however arising,
whether direct or acquired by the Bank by assignment or succession, whether due
or not due, absolute or contingent, liquidated or unliquidated, determined or
undetermined, and whether the Debtor may be liable individually or jointly with
others, or whether recovery upon any Indebtedness may be or hereafter becomes
barred by any statute of limitations or whether any Indebtedness may be or
hereafter becomes otherwise unenforceable.

2. Guaranty. The Guarantor unconditionally agrees to pay to the Bank or its
order, on demand, an amount equal to the amount of the Indebtedness or otherwise
perform any obligation of the Debtor undertaken pursuant to any Indebtedness. In
addition to any maximum principal liability hereunder, the Guarantor agrees to
(i) bear the expenses enumerated hereunder in the paragraph herein entitled
"Attorneys' Fees" and (ii) pay interest on the Indebtedness at the rate(s)
applicable thereto. Notwithstanding the foregoing, the Bank may allow the
Indebtedness to exceed the Guarantor's liability hereunder. Any payment by the
Guarantor shall not reduce the maximum principal obligation of the Guarantor
hereunder unless written notice to that effect is actually received by the Bank
at or prior to the time of such payment. Any payment by the Debtor or any other
person shall not reduce the Guarantor's maximum principal liability hereunder.

3. Right to Amend or Modify Indebtedness. The Guarantor authorizes the Bank, at
its sole discretion, with or without notice and without affecting the
Guarantor's liability hereunder, from time to time to: (i) change the time or
manner of payment, or any Indebtedness by renewal, extension, modification,
acceleration or otherwise; (ii) alter or change any provision of any
Indebtedness including, but not limited to, the rate of interest thereon, and
any document, instrument or agreement (other than this Guaranty), evidencing,
guaranteeing, securing or related to any Indebtedness; (iii) release, discharge,
exonerate, substitute or add one or more parties liable on any Indebtedness or
one or more endorsers, cosigners or guarantors for any Indebtedness; (iv) obtain
collateral for the payment of any Indebtedness or any guaranty thereof; (v)
release existing or after-acquired collateral on such terms as the Bank, in its
sole discretion, shall determine; (vi) apply any sums received from the Debtor,
any endorser, cosigner, other guarantor or other person liable on any
Indebtedness or from the sale or collection of collateral or its proceeds to
any indebtedness whatsoever owed or to be owed to the Bank by the Debtor in
any order or amount and regardless of whether or not such indebtedness is
guaranteed hereby, is secured by collateral or is due and payable; and (vii)
apply to any Indebtedness, in any order or amount, regardless of whether such
Indebtedness is secured by collateral or is due and payable, any sums received
from the Guarantor or from the sale of collateral in which the Guarantor has
granted the Bank a security interest.

4. Waivers. The Guarantor hereby unconditionally and irrevocably acknowledges
and agrees to the matters set forth below:

         A. Deficiency. In the event that any Indebtedness is now or hereafter
         secured by a deed of trust, the Guarantor waives any defense and all
         rights and benefits of those laws purporting to state that no
         deficiency judgment may be recovered on certain real property purchase
         money obligations (as presently contained in Section 580b of the
         California Code of Civil Procedure and as it may be amended or
         superseded in the future) and those laws purporting to state that no
         deficiency judgment may be recovered after a trustee's sale under a
         deed of trust (as presently contained in Section 580d of the
         California Code of Civil Procedure and as it may be amended or
         superseded in the future). THE GUARANTOR ACKNOWLEDGES THAT A
         FORECLOSURE BY A TRUSTEE'S SALE UNDER A DEED OF TRUST MAY RESULT IN
         THE DESTRUCTION OF THE GUARANTOR'S SUBROGATION RIGHTS THAT MAY
         OTHERWISE EXIST AND THAT A DESTRUCTION OF THOSE RIGHTS MAY CREATE A
         DEFENSE TO A DEFICIENCY JUDGMENT. THE GUARANTOR HEREBY SPECIFICALLY
         WAIVES ANY SUCH DEFENSE.

         B. Election of Remedies. The Guarantor waives any defense based upon
         the Guarantor's loss of a right against the Debtor arising from the
         Bank's election of a remedy on any Indebtedness under bankruptcy or
         other debtor relief laws or under any other laws, including, but not
         limited to, those purporting to reduce the Bank's right against the
         Guarantor in proportion to the principal obligation of any Indebtedness
         (as presently continued in Section 2809 of the California Civil Code
         and as it may be amended or superseded in the future).

         Without limiting the generality of the foregoing, the Guarantor
         waives all rights and defenses arising out of an election of remedies
         by the Bank, even though that election of remedies, such as a
         nonjudicial foreclosure with respect to security for a guaranteed
         obligation has destroyed the Guarantor's rights of subrogation and
         reimbursement against the Debtor by operation of Section 580d of the
         California Code of Civil Procedure or otherwise .

         C. Statute of Limitations. The Guarantor waives the benefit of the
         statute of limitations affecting the Guarantor's liability hereunder
         or the enforcement hereof.

         D. Action Against the Debtor and Collateral (and Other Remedies). The
         Guarantor waives all right to require the Bank to: (i) proceed against
         the Debtor, any endorser, cosigner, other guarantor or other person
         liable on any Indebtedness; (ii) join the Debtor or any endorser,
         cosigner, other guarantor or other person liable on any Indebtedness in
         any action or actions that may be brought and prosecuted by the Bank
         solely and separately against the Guarantor on any Indebtedness; (iii)
         proceed against any item or items of collateral securing any
         Indebtedness or any guaranty thereof; or (iv) pursue or refrain from
         pursuing any other remedy whatsoever in the Bank's power.

         E. Debtor's Defense. The Guarantor waives any defense arising by reason
         of any disability or other defense of the Debtor, the Debtor's
         successor or any endorser, cosigner, other guarantor or other person
         liable on any Indebtedness. Until all Indebtedness has been paid in
         full, even though it may be in excess of the liability incurred hereby,
         the Guarantor shall not have any right of subrogation and the Guarantor
         waives any benefit of and right to participate in any collateral now or
         hereafter held by the Bank. The Guarantor waives all presentments,
         demands for performance, notices of nonperformance, protests, notices
         of protest, notices of dishonor, notices of sale of any collateral
         securing any Indebtedness or any guaranty thereof, and notice of the
         existence, creation or incurring of new or additional Indebtedness.

         F. Debtor's Financial Condition. The Guarantor hereby recognizes,
         acknowledges and agrees that advances may be made in the future from
         time to time with respect to any Indebtedness without authorization
         from or notice to the Guarantor even though the financial condition of
         the Debtor, any endorser, cosigner, other guarantor or other person
         liable on any Indebtedness may have deteriorated since the date of this
         Guaranty. The Guarantor waives all right to require the Bank to
         disclose any information with respect to: (i) any Indebtedness now
         existing or hereafter incurred; (ii) the present or future financial
         condition, credit or character of the Debtor, any endorser, cosigner,
         other guarantor or other person liable on any Indebtedness; (iii) any
         present or future 

                                      (1)
<PAGE>
 
         collateral securing any Indebtedness or any guaranty thereof; or (iv)
         any present or future action or inaction on the part of the Bank, the
         Debtor or any endorser, cosigner, other guarantor or other person
         liable on any Indebtedness. The Guarantor hereby assumes the
         responsibility for being informed of the financial condition, credit
         and character of the Debtor and of all circumstances bearing upon the
         risk of non-payment of any Indebtedness which diligent inquiry would
         reveal.

5. Right of Set-off; Grant of Security Interest. In addition to all liens upon
and rights of set-off against any monies, securities or other property of the
Guarantor given to the Bank by law, the Bank shall have a security interest in
and a right to set off against all monies, securities and other property of
the Guarantor now or hereafter in the possession of or on deposit with the
Bank, the Bank's agents or any one or more of them, whether held in general or
special account or deposit or for safekeeping or otherwise; and each such
security interest and right of set-off may be exercised without demand upon or
notice to the Guarantor. No action or inaction by the Bank with respect to any
security interest or right of set-off shall be deemed a waiver thereof and
every right of set-off and security interest shall continue in full force and
effect until specifically released by the Bank in writing. The security
interest created hereby shall secure all of the Guarantor's obligations under
this Guaranty.

6. Right of Foreclosure. The Bank may foreclose, either by judicial foreclosure
or by exercise of power of sale, any deed of trust securing any Indebtedness
even though such foreclosure may destroy or diminish the Guarantor's rights
against the Debtor. The Guarantor shall be liable to the Bank for any part of
any Indebtedness remaining unpaid after any such foreclosure whether or not such
foreclosure was for fair market value.

7. Subordination. Any indebtedness of the Debtor or any endorser, cosigner,
other guarantor or other person liable on any Indebtedness now or hereafter owed
to the Guarantor is hereby subordinated to the Indebtedness. Such indebtedness
owed to the Guarantor shall, if the Bank so requests, be collected, enforced and
received by the Guarantor as trustee for the Bank and be paid over to the Bank
on account of the Indebtedness but without reducing or affecting in any manner
the liability of the Guarantor set forth herein. Should the Guarantor fail to
collect the proceeds of any such indebtedness owed to it and pay the proceeds to
the Bank, the Bank, as the Guarantor's attorney-in-fact, may do such acts and
sign such documents in the Guarantor's name as the Bank considers necessary to
effect such collection.

8. Invalid, Fraudulent or Preferential Payments. The Guarantor agrees that, to
the extent the Debtor or any endorser, cosigner, other guarantor or other person
liable on any Indebtedness makes a payment or payments to, or is credited for
any payment or payments made for or on behalf of the Debtor to the Bank, which
payment or payments, or any part thereof, is subsequently invalidated,
determined to be fraudulent or preferential, set aside or required to be repaid
to any trustee, receiver, assignee or any other party whether under any
bankruptcy, state or federal law or under any common law or equitable cause or
otherwise, then, to the extent thereof, the obligation or part thereof intended
to be satisfied thereby shall revived, reinstated and continued in full force
and effect as if such payment or payments had not originally been made or
credited.

9. Joint and Several Obligations; Independent Obligations. If more than one
Guarantor signs this Guaranty, the obligations hereunder are joint and several.
The Guarantor's obligations hereunder are independent of the obligations of the
Debtor or any endorser, cosigner, other guarantor or other person liable on any
Indebtedness and a separate action or actions may be brought and prosecuted
against the Guarantor on any Indebtedness.

10. Financial Information. The Guarantor hereby agrees to deliver or cause to be
delivered to the Bank:

         A. Other Information. (i) Financial Statements. Not later than April
         1st of each year, a copy of the personal financial statement of the
         Guarantor for such year; and (ii) Tax Returns. Within 10 days of filing
         but not later than October 31st of each year, a copy of the Guarantor's
         federal income tax returns filed for each year.

11. Acknowledgment of Receipt. Receipt of a true copy of this Guaranty is hereby
acknowledged by the Guarantor. The Guarantor understands and agrees that this
Guaranty shall not constitute a commitment of any nature whatsoever by the Bank
to renew or hereafter extend credit to the Debtor. The Guarantor agrees that
this Guaranty shall be effective with or without notice from the Bank of the
Bank's acceptance hereof.

12. Continuing Guaranty. This Guaranty is a continuing guaranty. Revocation
shall be effective only upon written notice personally received by an officer 
of
the Bank at the originating office indicated below or actually received at the
originating office by United States mail postage prepaid. Notice shall be
effective at any office of the Bank should the originating office no longer be
in existence. Revocation shall be effective at the close of the Bank's business
day when such notice is actually received. Any revocation shall be effective
only as to the revoking party and shall not affect that party's obligation with
respect to any Indebtedness existing before such revocation is effective.

13. Non-Reliance. In executing this Guaranty, the undersigned is not relying,
and has not relied, upon any statement or representation made by the Bank, or
any employee, agent or representative of the Bank, with respect to the status,
financial condition or other matters related to the Debtor or the relationship
between the Debtor and the Bank.

14. Multiple Guaranties. If the Guarantor has executed or does execute more than
one guaranty of any indebtedness of the Debtor to the Bank, the limits of
liability thereunder and hereunder shall be cumulative.

15. Severability. Should any one or more provisions of this Guaranty be
determined to be illegal or unenforceable, all other provisions shall remain
effective.

16. Corporate or Partnership Authority. If the Debtor is a corporation or
partnership, the Bank need not inquire into the power of the Debtor or the
authority of its officers, directors, partners or agents acting or purporting to
act in its behalf and any credit granted in reliance upon the purported exercise
of such power or authority is guaranteed hereunder.

17. Separate Property. Any married person who signs this Guaranty expressly
agrees that recourse may be had against such person's separate property for all
obligations hereunder.

18. Assignment. The Bank may, with or without notice, assign this Guaranty in
whole or in part. This Guaranty shall inure to the benefit of the Bank, its
successors and assigns, and shall bind the Guarantor and the Guarantor's heirs,
executors, administrators, successors and assigns.

19. Waiver of Jury. The Guarantor and the Bank hereby expressly and voluntarily
waive any and all rights, whether arising under the California constitution, any
rules of the California Code of Civil Procedure, common law or otherwise, to
demand a trial by jury in any action, matter, claim, or cause of action
whatsoever arising out of or in any way related to this Guaranty or any other
agreement, document or transaction contemplated hereby.

20.      Dispute Resolution.

         A. Disputes. It is understood and agreed that, upon the request of any
         party to this Guaranty, any dispute, claim or controversy of any kind,
         whether in contract or in tort, statutory or common law, legal or
         equitable, now existing or hereinafter arising between the parties in
         any way arising out of, pertaining to or in connection with : (i) this
         Guaranty, or any related agreements, documents or instruments, (ii) all
         past and present loans, credits, accounts, deposit accounts (whether
         demand deposits or time deposits), safe deposit boxes, safekeeping
         agreements, guarantees, letters of credit, goods or services, or other
         transactions, contracts or agreements of any kind, (iii) any incidents,
         omissions, acts, practices, or occurrences causing injury to any party
         whereby another party or its agents, employees or representatives may
         be liable, in whole or in part, or (iv) any aspect of the past or
         present relationships of the parties, shall be resolved through a
         two-step dispute resolution process administered by the Judicial
         Arbitration & Mediation Services, Inc. ("JAMS") as follows:

                                      (2)
<PAGE>
 
         B. Step I - Mediation. At the request of any party to the dispute,
         claim or controversy, the matter shall be referred to the nearest
         office of JAMS for mediation, which is an informal, non-binding
         conference or conferences between the parties in which a retired judge
         or justice from the JAMS panel will seek to guide the parties to a
         resolution of the case.

         C. Step II - Arbitration (Contracts Not Secured By Real Property).
         Should any dispute, claim or controversy remain unresolved at the
         conclusion of the Step I Mediation Phase, then (subject to the
         restriction at the end of this subparagraph) all such remaining matters
         shall be resolved by final and binding arbitor before a different
         judicial panelist, unless the parties shall agree to have the mediator
         panelist act as arbitrator. The hearing shall be conducted at a
         location determined by the arbitor in Los Angeles, California (or
         such other city as may be agreed upon by the parties) and shall be
         administered by and in accordance with the then existing Rules of
         Practice and Procedure of JAMS and judgment upon any award rendered by
         the arbitrator may be entered by any State or Federal Court having
         jurisdiction thereof. The arbitrator shall determine which is the
         prevailing party and shall include in the award that party's reasonable
         attorneys' fees and costs. This subparagraph shall apply only if, at
         the time of the submission of the matter to JAMS, the dispute or issues
         involved do not arise out of any transaction which is secured by real
         property collateral or, if so secured, all parties consent to such
         submission.

         As soon as practicable after selection of the arbitrator, the
         arbitrator, or the arbitrator's designated representative, shall
         determine a reasonable estimate of anticipated fees and costs of the
         arbitrator, and render a statement to each party setting forth that
         party's pro-rata share of said fees and costs. Thereafter, each party
         shall, within 10 days of receipt of said statement, deposit said sum
         with the arbitrator. Failure of any party to make such a deposit shall
         result in a forfeiture by the non-deposing party of the right to
         prosecute or defend the claim which is the subject of the arbitration,
         but shall not otherwise serve to abate, stay or suspend the arbitration
         proceedings.

         D. Step II - Trial By Court Reference (Contracts Secured By Real
         Property). If the dispute, claim or controversy is not one required or
         agreed to be submitted to arbitration, as provided in the above
         subparagraph, and has not been resolved by Step I mediation, then any
         remaining dispute, claim or controversy shall be submitted for
         determination by a trial on Order of Reference conducted by a retired
         judge or justice from the panel of JAMS appointed pursuant to the
         provisions of Section 638(l) of the California Code of Civil Procedure,
         or any amendment, addition or successor section thereto, to hear the
         case and report a statement of decision thereon. The parties intend
         this general reference agreement to be specifically enforceable in
         accordance with said section. If the parties are unable to agree upon
         a member of the JAMS panel to act as referee, then one shall be
         appointed by the Presiding Judge of the county wherein the hearing is
         to be held. The parties shall pay in advance, to the referee, the
         estimated reasonable fees and costs of the reference, as may be
         specified in advance by the referee. The parties shall initially
         share equally, by paying their proportionate amount of the estimated
         fees and costs of the reference. Failure of any party to make such a
         fee deposit shall result in a forfeiture by the non-depositing party
         of the right to prosecute or defend any cause of action which is the
         subject of the reference, but shall not otherwise serve to abate,
         stay or suspend the reference proceeding.

         E. Provisional Remedies, Self Help and Foreclosure. No provision of, or
         the exercise of any rights under any portion of this Dispute Resolution
         provision, shall limit the right of any party to exercise self help
         remedies such as set off, foreclosure against any real or personal
         property collateral, or the obtaining of provisional or ancillary
         remedies, such as injunctive relief or the appointment of a receiver,
         from any court having jurisdiction before, during or after the pendency
         of any arbitration. At the Bank's option, foreclosure under a deed of
         trust or mortgage may be accomplished either by exercise of power of
         sale under the deed of trust or mortgage, or by judicial foreclosure.
         The institution and maintenance of an action for provisional remedies,
         pursuit of provisional or ancillary remedies or exercise of self help
         remedies shall not constitute a waiver of the right of any party to
         submit the controversy or claim to arbitration.

21. Attorneys' Fees. Whether or not any suit, action, arbitration or other
dispute resolution proceeding is instituted, the Guarantor agrees to pay
reasonable attorneys' fees and all other costs and expenses which may be
incurred in the collection of any indebtedness, in the protection or
preservation of, or realization on, any collateral securing any Indebtedness and
in the enforcement by the Bank of this Guaranty.

22. Governing Law. This Guaranty shall be governed by and construed according to

                             INDEMNITY AGREEMENT

This Agreement is made and entered into by the undersigned Indemnitor
(Indemnitors) in favor of ACSTAR Insurance Company, 233 Main Street, New
Britain, CT 06050-2350 (Surety) for the purpose of inducing Surety to furnish
Bonds.

WHEREAS, in the transaction of business, certain bonds, undertakings and other
writings obligatory in the nature of a bond may have heretofore been, and may
hereafter be, required by, for, or on behalf of the Indemnitors or any one or
more of the Indemnitors, in whose bonds and undertakings the Indemnitors do
hereby affirm to have a substantial material and beneficial interest, and as a
condition precedent to the execution of any and all such bonds, the Surety
requires execution of this Indemnity Agreement.

WHEREAS, the Indemnitors have or may have a substantial, material and beneficial
interest in the obtaining of said bonds on behalf of various related companies,
it is agreed that this Agreement shall apply to any bonds executed on behalf of
any subsidiary, affiliated partnership, joint venture or corporation of the
Indemnitors, now existing or hereafter formed or acquired, and whether partially
or wholly owned or controlled, as fully as if the names and signatures of such
subsidiary or affiliates appeared herein as Indemnitors.

NOW, THEREFORE, in consideration of the foregoing premises, and of the execution
or continuance of such bonds and undertakings, and for other good and valuable
considerations the Indemnitors do, for themselves, their heirs, executors,
administrators and assigns jointly and severally agree with the Surety as
follows:

(1)      The Indemnitors will pay, when due, all premiums for each of such bonds
         in accordance with the Surety's rates in effect on the date each of
         such bonds become effective, as long as liability thereunder shall
         continue, and until the Surety is furnished with evidence satisfactory
         to the Surety of its discharge or release from the bonds or of all
         liability by reason thereof.

(2)      The Indemnitors will (a) perform all the conditions of each said bond
         or obligation, and any and all alterations, modifications, renewals,
         continuations, and extensions thereof, and (b) indemnify and save the
         Surety harmless from and against any and all liability, loss, costs,
         damages, fees of attorneys and other expenses which the Surety may
         sustain or incur by reason or in consequence of the execution of such
         bond or bonds and any renewal, continuation or successor thereof,
         including but not limited to (i) sums paid or liabilities incurred in
         settlement of, and expenses paid or incurred in connection with
         claims, suits or judgments under such bonds, or (ii) expenses paid or
         incurred (A) in enforcing the terms hereof, (B) in procuring or
         attempting to procure release from liability, or (C) in recovering or
         attempting to recover losses or expenses paid or incurred as
         aforesaid. In the event of payments by the Surety, the Indemnitors
         agree to accept the voucher of the Surety or other evidence of such
         payments as prima facie evidence of the propriety thereof, and of the
         Indemnitor's liability therefor to the Surety.

(3)      If the Surety shall set up a reserve to cover any claim, liability,
         suit or judgment under any such bond, the Indemnitors will, immediately
         upon demand, deposit with the Surety a sum of money equal to such
         reserve and any increase thereof as collateral security on such bond or
         bonds. Such sum and any other money or property which shall have
         been, or shall hereafter be, pledged as collateral security on any
         such bond or bonds shall, unless otherwise agreed in writing by the
         Surety, be available, in the discretion of the Surety, as collateral
         security on all bonds coming within the scope of this instrument or
         for any other indebtedness of the Indemnitors to the Surety.

(4)      The Surety, in its sole discretion, is authorized but not required,
         a)to consent to any change in the contract or the contract documents
         including the plans and specifications, b) to make or guarantee
         advances or loans for the purposes of executing the contract without
         any obligation to see to the application thereof, it being understood
         that the amount of all such advances or loans shall be conclusively
         presumed to be a loss hereunder for which the Indemnitors are liable,
         and c) in the event of any breach, delay or default asserted by the
         obligee in any said bonds, or in the performance of the contract, or a
         breach of this Agreement or of any bond or bonds connected therewith,
         or the failure to diligently prosecute the work under any contract, or
         a breach of this Agreement or of any bond or bonds connected therewith,
         or the failure to diligently prosecute the work under any contract,
         or to pay for labor and materials used the prosecution of the
         contract or in the event work has ceased or been suspended on any
         contract or contracts covered by any said bonds, to take possession
         of the work under the contract, at the expense of the Indemnitors to
         complete the contract or cause the same to be completed or to consent
         to the completion thereof, and to take any other action, which the
         Surety may deem appropriate. The Indemnitors hereby release and
         discharge the Surety from any and all liability for all its actions
         and omissions.

(5)      The Indemnitors hereby transfer, assign, pledge and convey to the
         Surety a security interest in 1) all equipment, tools, and material in
         which the Indemnitor have any interest, whether on site or elsewhere or
         on order, 2) all sums due or to become due to Indemnitors or any of
         them in connection with any contract, and 3) all subcontracts let by
         Indemnitors in connection with any contract. The security interests
         granted herein are effective in the case of each contract as of the
         date of the contract. Indemnitors hereby agree to execute any form of
         financing statement or other agreement or writing which Surety, in its
         sole discretion, deems necessary or advisable to perfect the security
         interests granted herein, and further authorize Surety at its
         discretion and at any time to file or serve this instrument, or a
         true copy hereof, or any other instrument executed pursuant hereto as
         a financing statement or other notice under the Uniform Commercial
         Code or any similar law, and Indemnitors authorize Surety to complete
         this instrument in any manner required for such use, and to prepare
         an attached schedule describing items of security covered hereunder.
         The Indemnitors hereby appoint Surety as Attorney-In-Fact for each of
         them to endorse and to deposit or negotiate checks, drafts and all
         similar instruments payable to Indemnitors, with the right, but not 
         the obligation to exercise all of the rights of the Indemnitors
         assigned, transferred and set over to the Surety in this Agreement
         and in the name of the Indemnitors to make, execute and deliver any
         and all additional assignments, documents as deemed necessary and
         proper by the Surety to give full force and effect to this paragraph
         (5). The Indemnitors agree that all equipment, tools, and material
         and all subcontracts are dedicated to the performance of the contract
         to which they pertain and that such equipment, tools and material and
         subcontracts shall be subject to a trust in favor of the contract
         owner and Surety and that they be used to that end.

(6)      The Surety shall have the exclusive right to determine for itself and
         the Indemnitors whether any claim or suit brought against the Surety or
         the principal upon any such bond shall be settled or defended and the
         Surety's decision shall be final and binding upon the Indemnitors.
<PAGE>
 
(7)      If any of the bonds are executed in connection with a contract which by
         its terms or by law prohibits the assignment of the contract price or
         any part thereof, Indemnitors covenant and agree that all payments due
         or received for or on account of said contract shall be held in trust
         for Surety for the payment of obligations incurred in the performance
         of the contract and for labor, materials, and services furnished in the
         prosecution of the work provided in such contract or any authorized
         extension or modification thereof, and, further, it is expressly
         understood that all monies due and to become due under any contact or
         contracts covered by the bonds shall be held in trust, whether such
         monies are in the possession of the Indemnitors or otherwise, for the
         benefit of and for payment of all such obligations in connection with
         any such contract or contracts for which the Surety would be liable
         under any of said bonds.

(8)      The Surety may, without incurring any liability, decline to execute any
         bond and if the Surety executed a bid or proposal bond it shall have
         the right to decline to execute any and all of the bonds that may be
         required in connection with any award that may be made under the
         proposal for which the bid or proposal bond is given and such
         declination shall not diminish or alter the liability of the
         Indemnitors that may arise by reason of having executed the bid or
         proposal bond.

(9)      The Indemnitors hereby waive notice of the execution of any such bonds
         or of any act, fact or information coming to the knowledge or notice of
         the Surety concerning or affecting its right or liabilities under any
         such bonds or rights or liabilities of the Indemnitors hereunder,
         notice of all such being hereby expressly waived.

(10)     If the Surety shall procure any other company or companies to execute
         or join with it in executing, or to reinsure any such bond or bonds,
         this instrument shall inure to the benefit of such other company or
         companies, its or their successors and assigns, so as to give to it
         or them a direct right of action against the Indemnitors to enforce
         this instrument and, in the event, the work "Surety", wherever used
         herein, shall be deemed to include such company or companies, as
         their respective interest may appear.

(11)     The Indemnitors hereby waive all rights to claim any of their property,
         including their respective homesteads, as exempt from levy, execution,
         sale or other legal process under the laws of any state.

(12)     In the event any claim or demand is made by the Surety against
         Indemnitors, or any one or more of them, by reason of the execution of
         a bond or bonds, the Surety is hereby expressly authorized to settle
         with any one or more of the Indemnitors individually, and with
         reference to the others, and such settlement or composition shall not
         affect the liability of any of the others, and the Indemnitors hereby
         expressly waive the right to be discharged and released by reason of
         the release of any one or more of the Indemnitors and hereby consent
         to any settlement or compromise that may hereafter be made. Separate
         suits may be brought hereunder as causes of action accrue and the
         bringing of suit or the recovery of judgment upon any cause of action
         shall not or bar the bringing of other suits upon other causes of
         action whether therefore of thereafter arising.

(13)     In the event any Indemnitor fails to execute this Agreement or in the
         event the execution hereof by any Indemnitor be defective or invalid
         for any reason, such failure, defect, or invalidity shall not in any
         manner affect the validity of this Agreement or the liability of any
         other Indemnitor executing the same, but each and every party so
         executing shall be and remain fully bound and liable.

(14)     This Agreement may be terminated by any Indemnitor upon twenty days
         written notice received by the Surety but any such notice of
         termination shall not operate to modify, bar or discharge the 
         Indemnitors as to the bonds that may have been theretofore executed.

(15)     This Agreement may not be changed or modified orally. No change or
         modification shall be effective unless make by written endorsement
         executed by the Surety and the Indemnitors to form a part hereof.

(16)     The Indemnitors agree to notify the Surety immediately upon their
         receiving any notice or knowledge that their liability insurance has
         been or will be cancelled or non-renewed, or that such coverage is or
         will be reduced.

         and all said Bonds is terminated, the Surety shall have the right to
         reasonable access to the books, records and accounts of the Indemnitor
         and Indemnitors, and any bank depository, materialman, supply house, or
         other person, firm or corporation when requested by the Surety is

         of such contracts and payments or accounts.

         singular or plural, are to be construed as referring to each of the
         undersigned Indemnitors, individually and collectively, though the

required from time to time to give certain bonds, undertakings, or instruments
of guarantee (all of which will hereinafter be included within the term "Bond"

contained. Payment of amounts due Surety hereunder together with legal
interest shall be payable upon demand.

indebtedness or liability of the Undersigned to the Surety, whether heretofore
or hereafter incurred, the following:

         (a) All right title and interest of the Undersigned in and to all
         machinery, equipment plant tools and materials which are, on the date

         thereto;

         (c) All rights, actions, causes of action, claims and demands
         whatsoever which the Undersigned or any of them may have or acquire in
         any subcontract in connection with said contract and against any
         subcontractor or any person, firm or corporation furnishing or agreeing
         to furnish or supply labor, materials, supplies, machinery, tools or
         other equipment in connection with or on account of said contract and

         proceeds thereof that at the time of abandonment, forfeiture or breach
         of said contract or such Bond or Bonds or of the terms of this
         Agreement or at the time of any advance, payment or guaranty by the
         Surety for the purpose of avoiding such abandonment, forfeiture or
         breach, may be due or may thereafter become due under said contract to
         or on behalf of the Undersigned, together with any and all sums due or
         which may thereafter become due under or on all other contracts, bonded
         or unbonded, in which any or all of the Undersigned have an
         interest.

FIFTH: Each of the Undersigned does hereby irrevocably nominate and appoint any
officer of the Surety the true and lawful attorney-in-fact of the Undersigned,
with full right and authority, in the event the Contractor fails or is unable to
complete the work called for by the contract guaranteed by any Bond or in the
event of the breach of any provision of this Agreement to execute on behalf of,
and sign the names of each of the Undersigned to, any voucher, release,
satisfaction, check, bill of sale of all or any property by this Agreement
assigned to the Surety or any other paper or contract necessary or desired to
carry into effect the purposes of this Agreement; with full right and authority
also, in such event, to dispose of the performance of said contract by
subletting the same in the name of the Contractor or otherwise; and each of the
Undersigned does hereby ratify and confirm all that such attorney-in-fact or the
Surety may lawfully do in the premises and further authorizes and empowers the
Surety and such attorney-in-fact and each of them to enter upon and take
possession of the tools, plant equipment, materials and subcontracts and all
other collateral security mentioned In this Agreement and enforce, use, employ
and dispose
<PAGE>
 
thereof for the purposes set forth in this Agreement. Each of the Undersigned
specifically agrees to protect, indemnity and hold harmless the Surety and such
attorney-in-fact against any and all claims, damages, costs and expenses that
may in any way arise or grow out of the exercise of the assignments contained in
this Agreement and the powers herein granted, specifically waiving any claim
which any Undersigned has or might hereafter have against the Surety or such
attorney-in-fact on account of anything done in enforcing the terms of this
agreement, assignments and power-of-attorney.

SIXTH: That the entire contract price of any contract referred to in a Bond or
Bonds, whether in the possession of the Undersigned or another, shall be and
hereby is impressed with a trust in favor of Surety for the payment of
obligations incurred for labor, materials and services in the performance of the
contract work for which Surety would be liable under such Bond or Bonds and for
the purpose of satisfying the conditions of the Bond executed in connection with
the contract.

SEVENTH: That if Surety shall be required or shall deem it necessary to set up a
reserve in any amount to cover any claim, demand, liability, expense, suit,
order, judgment or adjudication under or on any Bond or Bonds or for any other
reason whatsoever, to immediately upon demand deposit with Surety an amount of
money sufficient to cover such reserve and any increase thereof, such funds to
be held by Surety as collateral, in addition to the indemnity afforded by this
instrument, with the right to use such funds or any part thereof, at any time,
in payment or compromise of any liability, claims, demands, judgment, damages,
fees and disbursements or other expenses; and the Undersigned, in the event of
their failure to comply with such demand, hereby authorize and empower any
attorney or any court of record of the United States or any of its territories
or possessions, to appear for them or any of them in any suit by Surety and to
confess judgment against them or any of them for any sum or sums of money up
to the amount of any or all Bond or Bonds, with costs, interest and reasonable
attorneys' fees; such judgment, however, to be satisfied upon the payment of
any and all such sums as may be found due by the Undersigned to Surety under
the terms of this Agreement. Demand shall be sufficient if sent by registered
or certified mail to the Undersigned at the address or addresses given herein
or last known to Surety, whether or not actually received. The authority to
confess judgment as set forth herein shall not be exhausted by any one
exercise thereof, but may be exercised from time to time and more than one
time until all liability of the Undersigned to Surety shall have been paid in
full.

EIGHTH: All collateral security held by or assigned to the Surety may be used by
the Surety at anytime in payment of any claim, loss or expense which the
Undersigned have agreed to pay hereby, whether or not such claim, loss or
expense arises out of or in connection with such Bond or contract under which
such collateral is held. The Surety may sell or realize upon any or all such
collateral security, at public or private sale, with or without notice to the
Undersigned or any of them, and with the right to be purchaser itself at any
such public sale, and shall be accountable to the Undersigned only for such
surplus or remainder of such collateral security or the proceeds thereof as may
be in the Surety's possession after it has been fully indemnified as in this
Agreement provided. The Surety shall not be liable for decrease in value or loss
or destruction of or damage to such security, however caused.

NINTH: The Surety shall have the right at its option and in its sole
discretion:

         (a) To deem this Agreement breached should the Contractor become
         involved in any agreement or proceeding of liquidation, receivership,
         or bankruptcy, voluntarily or involuntarily, or should the Contractor
         if an individual die, be convicted of a felony, become a fugitive from
         justice, or for any reason disappears and cannot immediately be found
         by the Surety by use of usual methods.

         (b) To take possession of the work under any contract and at the
         expense of the Undersigned to complete or to contract for the
         completion of the same, or to consent to the reletting of the
         completion thereof by the obligee in said contract Bond or Bonds, or to
         take such other steps as in the discretion of the Surety may be
         advisable or necessary to obtain its release or to secure itself from
         loss thereunder.

         (c) To adjust settle or compromise any claim, demand, suit or judgment
         upon said Bond or Bonds, or any of them.

         (d) To increase or decrease the penalty or penalties of any such Bond
         or Bonds, to change the obligee or obligees therein, to execute any
         continuations, enlargements, modifications and renewals thereof or
         substitute therefore with the same or different conditions,
         provisions and obligees, and with the same or larger or smaller
         penalties, it being agreed that this instrument shall apply to and
         cover such new or changed bonds or renewals even though the consent
         of the Surety may or does substantially increase the liability of the
         Contractor and the Undersigned and to take such steps as it may deem
         necessary or proper to obtain release from liability under any such
         Bond or Bonds.

All damage, loss or expense of any nature which the Surety may incur under
Section Ninth shall be borne by the Undersigned.

TENTH: The Surety shall have the exclusive right for itself and for the
Undersigned to decide and determine whether any claim, demand, suit or judgment
upon said Bond or Bonds shall, on the basis of liability, expediency or
otherwise, be paid, settled, defended or appealed, and its determination shall
be final, conclusive and binding upon the Undersigned; and any loss, costs,
charges, expense or liability thereby sustained or incurred, as well as any and
all disbursements on account of costs, expenses and attorneys' fees, deemed
necessary or advisable by the Surety, shall be borne and paid immediately by the
Undersigned, together with legal interest In the event of any payment settlement
compromise or investigation, an itemized statement of the payment loss, costs,
damages, expenses or attorneys' fees, sworn to by any officer of the Surety or
the voucher or vouchers or other evidence of such payment settlement or
compromise, shall be prima facie evidence of the fact and extent of the
liability of the Undersigned to the Surety in any claim or suit hereunder and in
any and all matters arising between the Undersigned and the Surety.

ELEVENTH: The Surety is further authorized and empowered to advance money or to
guarantee loans to the Contractor which the Surety may see fit to advance to
said Contractor for the purpose of any contract referred to in or guaranteed by
said Bond or Bonds; and all money so loaned or advanced and all costs,
attorneys' fees and expenses incurred by the Surety in relation thereto, unless
repaid with legal interest when due, shall be conclusively presumed to be a loss
by the Surety for which each and all of the Undersigned shall be responsible,
notwithstanding said money or any part thereof so loaned or advanced to the
Contractor for the purpose of any such contract should not be so used by the
Contractor. The Undersigned hereby waive all notice of such advance or loan, or
of any default or any other act or acts giving rise to any claim under any said
Bond or Bonds, and waive notice of any and all liability of the Surety under any
said Bond or Bonds or any and all liability on the part of the Undersigned to
the effect and end that each of the Undersigned shall be and continue liable to
the Surety hereunder notwithstanding any notice of any kind to which the
Undersigned might have been or be entitled and notwithstanding any defenses
which the Undersigned might have been or be entitled to make.

TWELFTH:  No assent, assignment, change in time or manner of payment or other
change or extension in the terms of any Bond or of any contract referred to in
such Bond or in the general conditions, plans or specifications incorporated in
such contract granted or authorized by the Surety or the refusal to so grant or
authorize, shall release, discharge or in any manner whatsoever affect the
obligations assumed by the Undersigned in executing this Continuing Agreement of
Indemnity. This Agreement shall apply to any and all renewal, continuation or
substitution bonds executed by the Surety, The Surety shall not be required to
notify or obtain the approval or consent of the Undersigned prior to granting,
authorizing or executing any assent, assignment, change or extension. The Surety
shall have the absolute right to cancel any bond in accordance with any
cancellation provision contained therein and the Surety is hereby released from
any liability for expenses, costs, or damage alleged to be sustained by the
Undersigned by reason of such cancellation.

THIRTEENTH: Until the Surety shall have been furnished with competent legal
evidence of its discharge without loss from any and all Bonds, the Surety shall
have the right at all times to free access to the books, records and accounts of
each of the Undersigned for the purpose of examining the same. Each of the
Undersigned hereby authorizes and requests any and all depositories in which
funds of any of the Undersigned may be deposited to furnish to the Surety the
amount of such deposits as of any date requested and any person, firm or
corporation doing business with the Undersigned is hereby authorized to furnish
any information requested by the Surety concerning any transaction. The Surety
may furnish copies of any and all statements, agreements and financial
statements and any information which it now has or may hereafter obtain
concerning each of the Undersigned, to other persons or companies for the
purpose of procuring co-suretyship or reinsurance or of advising interested
persons or companies.

FOURTEENTH: Each of the Undersigned does hereby waive all right to claim any
property, including homestead as exempt from levy, execution, sale or other
legal process under the law of any state, province or other government as
against the rights of the Surety to proceed against the same for indemnity
hereunder.

FIFTEENTH: The Surety shall have every right and remedy which a personal surety
without compensation would have, including the right to secure its discharge
from the suretyship and nothing herein contained shall be considered or
construed to waive, abridge or diminish any right or remedy which the Surety
might have if this instrument were not executed. The Undersigned will, on
request of the Surety procure the discharge of the Surety from any Bonds, and
all liability by reason thereof. Separate suits may be brought hereunder as
causes of action may accrue, and the pendency or termination of any such suit
shall not bar any subsequent action. The Surety shall be notified immediately by
the Undersigned of any claim or action which may result in a claim against the
Surety, such notice to be given by registered mail to the Surety at its Home
Office. In the event of legal proceedings against the Surety, upon or on account
of any said Bond or Bonds, the Surety may apply for a court order making
any or all of the Undersigned parties defendants, and each Undersigned hereby
consents to the granting of such application and agrees to become such a party
defendant and to allow judgment in the event of judgment against the Surety,
to be rendered also against such Undersigned in like amount and in favor of
the Surety, if the Surety so desires.
<PAGE>
 
SIXTEENTH: The Surety reserves the right to decline to execute any such Bond;
and if it shall execute any proposal Bond, and if the Contractor is awarded the
contract, the Contractor shall not be obligated to obtain any Bond or Bonds
required by the contract from the Surety nor shall the Surety be obligated to
execute such Bond or Bonds.

SEVENTEENTH: This Agreement shall, in all its terms and agreements, be for the
benefit of and protect any person or company joining with the Surety in
executing said Bond or Bonds, or any of them, or executing at the request of the
surety said Bond or Bonds, or any of them as well as any company or companies
assuming co-suretyship or reinsurance thereon.

EIGHTEENTH: The Undersigned warrant that each of them is specifically and
beneficially interested in the obtaining of each Bond. Failure to execute, or
defective execution, by any party, shall not affect the validity of this
obligation as to any other party executing the same and each such other party
shall remain fully bound and liable hereunder. Invalidity of any portion or
provision of this Agreement by reason of the laws of any state or for any other
reason shall not render the other provisions or portions hereof invalid.
Execution of any application for any Bond by the Contractor, or of any other
indemnity agreement by any Undersigned for the Contractor shall in no way
abrogate, waive or diminish any rights of Surety under this Agreement. The
Undersigned acknowledge that the execution of this Agreement and the undertaking
of indemnity was not made in reliance upon any representation concerning the
financial responsibility of any Undersigned, or concerning the competence of the
Contractor to perform.

NINETEENTH: Each of the Undersigned expressly recognizes and covenants that this
Agreement is a continuing obligation applying to and indemnifying the Surety and
that the rights of Indemnification of each Surety signatory to this Agreement
shall be individual and not joint with those of the other signatory Sureties as
to any and all Bonds (whether or not covered by any application signed by
Contractor--such application to be considered between the parties hereto as
merely supplemental to this Continuing Agreement of Indemnity) heretofore or
hereafter executed by Surety on behalf of Contractor (whether contracting alone
or as a Co-venture) until this Agreement shall be canceled in the manner
hereinafter provided. Any of the Undersigned may notify the Surety(ies) at its
Head Office, of such Undersigned's withdrawal from this Agreement; such notice
shall be sent by certified or registered mail and shall state when, not less
than thirty days after receipt of such notice by the Surety, such withdrawal
shall be effective. Such Undersigned will not be liable under this Agreement
as to any Bonds executed by the Surety after the effective date of such
notice; provided, that as to any and all such Bonds executed or authorized by
the Surety prior to effective date of such notice and as to any and all
renewals, continuations and extensions thereof or substitutions therefore
(and, if a proposal or Bid Bond has been executed or authorized prior to such
effective date, as to any contract Bond executed pursuant thereto) regardless
of when the same are executed, such Undersigned shall be and remain fully
liable hereunder, as if said notice had not been served. Such withdrawal by
any Undersigned shall in no way affect the obligation of any other Undersigned
who has given no such notice of termination.

TWENTIETH: That this Agreement or a carbon, photographic, xerographic or other
reproduction or copy of this Agreement shall constitute a Security Agreement to
Surety and also a Financing Statement both in accordance with the provisions of
the Uniform Commercial Code of every jurisdiction wherein such Code is in 
effect, but that the filing or recording of this Agreement shall be solely at
the option of Surety and that the failure to do so shall not release or impair
any of the obligations of the Undersigned under this Agreement or otherwise
arising, nor shall such failure be in any manner in derogation of the rights of
Surety under this Agreement or otherwise.

        brought to the charging subsystem and dumped in airlock hopper and
        pushed/fed into the process chamber at a controlled rate. Feedstock
        loses its compaction while being gasified, and falls on the molten
        glass. The char on top of molten glass reacts with oxygen to form
        offgas. Inorganic/mineral residues remain on top and melt and sink into
        molten glass.

        The process chamber is initially heated with propane/air until the glass
        is hot enough to carry current, at which time a Joule heating subsystem
        takes over. The process chamber is constructed of special refractory
        bricks enclosed in a steel box. The chamber consists of a gasification
        hearth and a polishing hearth. In oxidation mode, oxygen or air is used
        for reaction with the feed material. In reduction mode oxygen mixed with
        steam may be used for reaction.

        Organic material reacts with oxygen in the gasification hearth and
        inorganic/minerals melt and sink into the molten glass. Some ash and
        fine particles become airborne with offgas leaving the gasification
        hearth but will settle and fall into molten glass in the polishing
        section.

        During normal operation, molten glass is tapped periodically through a
        side discharge valve and poured into a drum. During maintenance, the
        glass is drained out of the chamber by a set of drain valves located in
        the bottom of the chamber. Next the glass is poured into a water bath to
        make pebbles. When maintenance is complete, these pebbles are fed back
        into the process chamber and are reused.

        The process chamber is followed by an air pollution control subsystem
        which is not included in this agreement. Air pollution control subsystem
        will consist of a rapid quencher, baghouse filter, scrubber, draft fan,
        HEPA/charcoal filters and exhaust fans. Scrubber is an optional item and
        may be excluded form the process since processing of waste that produces
        a significant amount of acid gas is not anticipated.

        2.  SYSTEM FUNCTION

        The primary function of the system is to significantly reduce the volume
        of the feedstock. The secondary function of the system is to make a
        solid product that is satisfactorily non-leachable.

        3.  FEEDSTOCK DESCRIPTION

        Feedstock to the system is a highly heterogeneous low-level, radioactive
        waste and may include individually or a mixture of organic and inorganic
        material such as process sludges, powders, bulk plastics, wood,
        clothing, mineral material, soil, absorbent material, rubber, wipers,
        gloves, coveralls and the like. Metals will be removed from the
        feedstock as much as possible, but small metal pieces such as pins,
        clips, nails, buttons will be included in the feedstock. Metal buildup
        in the melter will effect the service life of the melter.
