Item 1.     Business

Introduction

ETS International, Inc. ("ETSI"), a Virginia corporation, is a technology
based firm which provides environmental and infrastructure products and
services.  ETSI specializes in toxic emission measurement and control, as
well as infrastructure design, construction and maintenance.  ETSI operates
through four wholly-owned affiliates:  ETS, Inc., ETS Analytical Services,
Inc., ETS Water and Waste Management, Inc. and ETS Liner, Inc., a subsidiary
of ETS Water and Waste Management, Inc.

ETS, Inc. ("ETS"), a Virginia corporation, owns the proprietary rights to a
number of patented inventions.  Resources have been allocated for the
commercialization of two of these inventions.  The first of these proprietary
systems, the Limestone Emission Control System is designed to address the
acid rain problem by eliminating greater than 90 percent sulfur oxide
emissions from electric power plants and industry.  The first commercial
system is operating in Taiwan.  The second invention, the Baghouse
Performance Monitor ("BPM"), is a patented instrument which serves as an
early warning system of industrial dust collector malfunctions.  A number of
Baghouse Performance Monitor systems are operating in the United States.

The services offered by ETS generally include:  training, contract research
and development, engineering, consulting, regulatory assistance and field
testing.  These services and related unique capabilities have been the
springboard from which ETS has developed its patented air pollution control
products and systems.  

ETS Analytical Services, Inc. ("ETSAS"), a Virginia corporation, is an
environmentally oriented analytical laboratory serving both government and
industry.  ETSAS has executed numerous United States Environmental Protection
Agency ("USEPA") contracts and has been a contract authorized Superfund
laboratory participating in the USEPA's Contract Laboratory Program.  ETSAS
currently is executing a multi-year contract for the USEPA's Office of Water. 
In addition to a number of industrial clients, ETSAS is known for its work
with electric utilities.  The lab specializes in the areas of trace
environmental analysis, methods development and research and development.  In
addition, ETSAS provides comprehensive field and laboratory services relating
to wastewater/treatability, water/drinking water, OSHA compliance and toxic
substances.  

ETS Water and Waste Management, Inc. ("ETSW"), organized under Virginia law
and headquartered in Richmond, Virginia, is a construction and maintenance
service firm whose history dates back to 1947.  ETSW provides storm and sewer
line, water system and gas line construction with a special focus, through
its subsidiary, ETS Liner, Inc. ("ETSL"), which is headquartered in Orlando,
Florida, on trenchless rehabilitation, i.e., the repair of sewer and water
lines by relining these lines without digging up and replacing them.  ETSW
also designs and installs septic systems and irrigation systems. 
Additionally, related repair and maintenance services are provided.  Among
its customers are municipalities, government agencies, Fortune 500 companies
and developers.  ETSW has completed major infrastructure projects in eastern
Virginia and the greater Washington, D.C. area.  
<PAGE>

ETSI divides its revenues into four categories:  (a) services - encompassing
field and analytical testing, regulatory assistance and monitoring;
(b) consulting/engineering - encompassing consulting and engineering services
and educational areas; (c) products; and (d) construction.  In fiscal 1997,
77% of ETSI's total revenues came from the construction operations of ETSW,
20% came from the testing service operations of ETS and ETSAS and 3% came
from the consulting/engineering and products operations of ETS.  In fiscal
1996 and 1995, the following percentages of ETSI's total revenues were
derived from its affiliates' products and services:  Fiscal 1996:  69% from
construction, 29% from testing service and 2% from consulting/engineering and
products.  Fiscal 1995:  67% from construction, 31% from testing service and
2% from consulting/engineering and products.  See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

History

ETSI, a Virginia corporation, was incorporated on February 25, 1987.  On
January 28, 1988, it acquired all of the issued and outstanding common stock
of ETS from John D. McKenna and John C. Mycock (officers and directors of
ETSI) and two others, and the next day completed a public offering pursuant
to the rules of the Vancouver Stock Exchange ("VSE").  On October 29, 1989,
certain sophisticated analytical laboratory equipment of Centec Analytical
Services, Inc. ("Centec"), an analytical laboratory, were purchased by ETSI
and, in 1990, placed in ETSAS.  In 1992, the common stock of ETSI commenced
trading on the Emerging Company Marketplace of the American Stock Exchange;
and ETSI voluntarily delisted its securities from the VSE.

In June, 1994, ETSI exchanged 2,730,000 of its shares of common stock
("Shares of Common Stock") for all the outstanding common stock of Stamie E.
Lyttle Co., Inc., Lyttle Utilities, Inc. and LPS Corp., all of which were
merged into ETSW.  In January, 1995, Environmental Laboratories Incorporated,
an environmental laboratory located in Richmond, Virginia, was merged into
ETSAS, the Company's analytical laboratory subsidiary, in exchange for
183,600 Shares of Common Stock issued to its stockholders; and, in April,
1995, the assets of Air Compliance, Inc. were acquired by ETS, Inc., the
Company's air quality subsidiary, for 113,000 Shares of Common Stock issued
to Air Compliance, Inc.

In February, 1996, ETSI acquired certain assets of Olympic Industries, Inc.,
Pompano Beach, Florida, for 539,130 Shares of Common Stock.  The assets were
placed in a newly-formed corporation, ETSL, which is a wholly-owned
subsidiary of ETSW, and the business just moved to Orlando, Florida.  The
focus of ETSL's business is trenchless rehabilitation of aging sewer lines.  

In April, 1996, ETSI acquired the assets of an environmental laboratory in
Fairfax, Virginia, from Dewberry & Davis in exchange for 65,617 Shares of
Common Stock.  The assets were placed in ETSAS and continue to be operated at
the same location.

The Subsidiaries

ETS, Inc.

History and Overview

ETS, formed in 1973, has been engaged in designing, manufacturing and
supplying air pollution control systems, with particular emphasis on fabric
filter particulate collectors, providing software and testing services to
industry and utilities and conducting industrial and government contract
research and development.  It also has developed three products designed for
use in the air pollution control industry - the Limestone Emission Control
System, the Baghouse Performance Monitor and the Dry Reactor.  It has
suspended the development of one product, the Reduced Entrainment
Precipitator, until suitable funding can be obtained, of which there is no
guarantee.  In fiscal 1997, ETS's service business generated almost all of
its operating revenues.  Since its acquisition by ETSI in 1988, ETS has
expanded the services it offers, particularly in the fields of air pollution
control, consulting, regulatory assistance, toxic emission testing, asbestos
surveys and fabric filter testing and has developed and sold related systems
and products.  It intends to continue to develop, market and license
proprietary products for the air pollution control industry.  In April, 1995,
ETS expanded its service area to Pennsylvania and New Jersey through the
acquisition of the assets of Air Compliance, Inc., an air pollution control
and toxic emission testing company, located in Feasterville, Pennsylvania. 

Products

The Limestone Emission Control System (the "LEC")

The LEC is an air pollution control system which controls acid gas and
particulate emissions from utility and industrial boilers.  Development of
the LEC began in 1982 and was successfully completed in 1993.  In December
1994, a commercial unit was constructed and is currently in operation.  Since
the close of fiscal 1997, ETS has entered a letter of intent with a Taiwan
firm, contingent upon successful negotiations and posting a performance bond,
to supply three of the Company's Limestone Emission Control Systems, which
will take two years to install and start-up.

In the LEC, hot sulfur dioxide ("SO2") laden flue gas passes through the
cross section of a vertical moving bed of standard quarry limestone ("CaCO3")
gravity fed from a hopper and covered by a thin film of water.  The rate of
flow of the limestone can be adjusted by varying the speed of a screw
conveyor into which the limestone falls.  Sulfur dioxide is absorbed from the
flue gas into the water and subsequently reacts with the limestone to form a
surface layer principally of calcium sulfate ("CaSO2") and calcium sulfite
("CaSO3").  The limestone granules are then reactivated by mild abrasion to
remove the calcium sulfite and calcium sulfate layers.  The particles of
calcium sulfate and calcium sulfite fall through a fine screen, thereby
exposing the active limestone for further reaction.  Gypsum, the waste
product, is the main content of wallboard.

Management believes that the gypsum produced by the LEC will be readily
marketable by utilities or other users as it conforms to commercial
standards.  The recycled limestone, supplemented by a new supply, is then fed
back into the hopper for continued reaction with flue gas.
<PAGE>
Title IV of the Clean Air Act Amendments of 1990 ("CAAA") deals with the
prevention of smokestack pollution causing "acid rain."  It finds that acidic
compounds and their precursors in the atmosphere threaten natural resources,
ecosystems, materials, visibility and public health and that the principal
sources of acid rain are sulfur dioxide and nitrous oxides.  It regulates the
emissions of those substances from fossil fuel fired combustion devices, in
part by permitting companies with low emissions to trade pollution credits
with companies with higher levels.  As a consequence, the LEC, with its
ability to remove 99% sulfur dioxide may be considered attractive in meeting
the SO2 Allowance Program and the ability of companies to trade pollution
credits.

On June 23, 1992, ETS entered into a license agreement with Procedair
Industries, Montreal, Canada, a subsidiary of Stein Heurtey, an industrial
furnace manufacturer and a sister company of Procedair, S.A., a French air
pollution control firm, and EGCI, S.A., a French engineering firm
specializing in combustion, to license the LEC.  The license was extended on
July 1, 1995 for a period of twelve months.  Presently, this agreement has
been extended orally on an "at will" basis.  The license is exclusive in
North America and non-exclusive outside North America.  ETS will receive
royalties at the rate of 8% of sales until a sales level of $8,333,333 is
reached.  Thereafter, until the expiration of the agreement, ETS will receive
royalties of 5% of sales.  ETS is obligated to maintain patents, provide and
make available know-how, provide sufficient information to enable the
licensee to design applications for the system, to make available fully
qualified and competent employees and make available technical information
and sales support at specified levels.  No sales have resulted from this
agreement to date and there is no assurance that any royalties will be
generated.

In February, 1993, ETS entered into a license agreement with U-Tah Industrial
Company, Ltd. ("U-Tah") located in Taipei, Taiwan to market the LEC within
Taiwan, R.O.C.  The five year contract calls for U-Tah to provide ETS an
up-front license fee, followed by 5% royalties on LEC system sales.  In 1993,
ETS opened an office in Taipei, to provide technical support to its
licensees.  In March, 1994, the first commercial sale of the LEC system was
made through U-Tah to Shing Ming Metal Industrial Company, a plant near
Taipei.  The plant is modest in size, but represents, to ETS, an opportunity
to prove the technology on a commercial basis.  The LEC system was made
operational in December, 1994 and has performed pursuant to its
specifications to date.  Management believes that this installation
represents a breakthrough for future sales as it proves the LEC technology in
ability to remove SO2 from smokestack emissions on a commercially viable
basis as well as its reliability and its cost effectiveness.  No sales have
resulted from this agreement to date, and there is no assurance that any
royalties will be generated.  In November 1996, ETS granted a license to E &
C Engineering Corporation for the exclusive right to sell the LEC throughout
Taiwan, R.O.C.  Since the close of fiscal 1997, ETS received a Letter of
Intent from China Steel Corporation, in Taiwan, to supply three LEC systems,
contingent upon successful negotiations and posting a performance bond. 

The Baghouse Performance Monitor (the "BPM") and the Baghouse Performance
Monitor Expert System 

A baghouse, also referred to as a "fabric filter," is essentially a
collection of numerous fabric bags.  Baghouses are the leading method of
collecting particulates from industrial and commercial smokestacks.  Of the
250,000 baghouses presently operating in the United States, ETSI has targeted
the 2,500 largest as its present market.  Each bag works in a fashion similar
<PAGE>
to a vacuum cleaner to trap dust and particulate matter from a gas stream. 
However, as particulates collect on the fabric of each bag, they form a dust
cake which develops increasing resistance to the flow of gas.  Thus, the dust
cake must be periodically removed to maintain system flow stability.  

The BPM, and its associated expert system software (both devices referred to
as the "BPM," unless otherwise noted), collects, organizes, displays and
assists the analysis of all the important parameters of a baghouse emission
control system.  Its primary purpose is to monitor current status and
stability, warn operators of any system instability or developing problems
and prepare an easy to access and use database of operational history for any
necessary troubleshooting.  A BPM can directly monitor the flow and pressure
drop characteristics of many individual bags within an operating baghouse,
thus providing the capability of simultaneous side-by-side evaluations of
alternative fabrics, designs, or operational methods.  To date, the BPM has
been utilized extensively for this purpose in all types of baghouses.

The BPM is manufactured to order from standard components, such as printed
circuit boards and fabricated metal parts which are readily available from
multiple sources.  After purchase, materials and components are inventoried
and some subassemblies are completed in-house.  Upon receipt of an order,
ETSI technicians assemble, calibrate and test the devices prior to shipment
and installation.  ETS's present manufacturing facilities are considered
adequate.

ETS's marketing strategy for the BPM has been to concentrate on the utility
and large industrial baghouse markets which include utilities, industrial
boilers, chemical plants, forest products plants, steel mills, cement plants
and nonferrous mining and smelting operations.  ETS believes that potential
customers in these markets may require a monitoring system.  Bag replacement
costs are relatively high and a small percentage of savings justifies the
purchase of this relatively inexpensive monitor.  In addition, reduced
baghouse capacity may reduce performance of a given customer's production
rates and may result in emissions of unacceptable levels of pollutants and
the closure of the process and/or imposition of monetary penalties.

The first commercial BPM installation was completed in 1983.  Customers have
included chemical plants, steel mills, glass manufacturers, foundries,
industrial coal-fired boilers and utilities.  The BPM has been described in
literature published by the Electric Power Research Institute, Inc. ("EPRI"),
which is distributed to all electric utilities.  The EPRI refers all
inquiries to ETS.  To implement its marketing strategy, ETS has initiated a
direct mail advertising campaign and employs in-house sales personnel.  In
addition, ETS conducts technical seminars and has entered into agreements
with firms in both Mexico and Taiwan for the sale and servicing of the BPM.

ETS believes that strict enforcement of Title IV of the CAAA dealing with
permitting would have a positive impact on sales of the BPM.  At present,
enforcement is lax and sales of the BPM have been sporadic.  Title IV
requires that after the effective date of any permit program relating to
major sources of pollution, it would be unlawful to violate the conditions of
such a permit.  States are required, within three years, to submit a
conforming permit program.  Major sources are those which emit, per year, ten
tons of any hazardous air pollutant or a combination of 25 tons of hazardous
air pollutants.  Title III of the CAAA relating to Air Toxics establishes a
list of 189 substances and compounds which must be considered hazardous air
pollutants and a procedure for review of that list.  Title VII of the CAAA
expands and defines the authority of the individual states to include
enhanced monitoring and requires major source owners to demonstrate
compliance at regular intervals using approved continuous monitoring
technology which the BPM can provide.<PAGE>

The Dry Reactor

The "Dry Reactor" is an air pollution control system designed to control
emission of acid gases, such as hydrochloric acid, sulfur oxides and nitrous
oxides and particulates.  Hot flue gases pass through the Dry Reactor, and
the acid gases and particles are substantially removed before the flue gases
enter the atmosphere.  The Dry Reactor has applications for emission control
in hospital and hazardous waste incinerators and small municipal solid waste
facilities.  Both the LEC and the Dry Reactor use a dry scrubber system to
control acid gas pollutants.  However, the Dry Reactor is a smaller, modular
unit, designed for use in smaller installations, whereas the LEC is targeted
at larger utility and industrial boilers.

The Dry Reactor uses a process called a "dry" scrubber, in contrast to
competing "wet" and "semidry" (sometimes referred to as "half-dry" or
"spraydrying") systems.  In wet and semidry systems, when noxious gases are
brought into contact with alkaline materials, these systems produce liquid
wastes which must be handled with pumping and plumbing systems.  Such waste
often is corrosive, causing scaling, flaking and clogging of the handling
systems and requiring further treatment.  In the Dry Reactor, flue gas is
directed into a chamber where it is mixed with a dry reagent (lime) by the
mechanical action of a rotating plate, known as a "slinger."  The slinger
delivers the lime perpendicularly to the flue gas allowing intimate contact
of the dry reagent and any pollutants in the flue gas.  This contact causes a
reaction which forms a non-acidic compound and removes as much as 90% of
unwanted acid gases.  An internal recirculator, located above the slinger,
increases the contact time, thus enhancing the removal of pollutants.

ETS's only commercially sold Dry Reactor was installed at the Fairfax
Hospital, Fairfax, Virginia in 1987 and was successfully operated until
recently when they discontinued the use of their incinerator.  It has removed
greater than 98% of unwanted acid gases since installation without
degradation or greater than normal maintenance.  In management's opinion,
future sales, if any, of the Dry Reactor will be generated through increasing
enforcement and the imposition of tougher standards of clean air legislation
and regulations.  Specifically, the CAAA institutes a program under which all
subject air pollution sources must obtain an operating permit.  The USEPA is
responsible for issuing regulations and monitoring compliance.  The various
states must develop and implement the programs.  If a state fails to develop
or implement such a permitting program, the USEPA must develop and implement
a federal permit program for that state.  However, until enforcement is
strengthened, ETS does not contemplate substantial sales, if any, of the Dry
Reactor.

In 1992, Gibbson Engineering Company Ltd. ("Gibbson"), located in Taipei,
Taiwan, was granted the exclusive right to market the Dry Reactor throughout
Taiwan, R.O.C.  The agreement provides that Gibbson pay ETS an up-front
license fee followed by a 7% royalty fee on all system components.  No sales
have resulted from the agreement, and there is no assurance that any
royalties will be generated.

The Reduced Entrainment Precipitator (the "REP")

An electronic precipitator gives dust particles an electric charge which
attracts them out of a gas stream onto the sidewalls of the collector for
subsequent collection and disposal.  However, in standard designs, not all
the dust particles remain captured on the side walls and some become
dislodged by the gas motion and are "re-entrained" in the gas flow.  The REP
prevents reentrainment of dust particles.  The REP uses a conventional
electrostatic precipitator to attract dust particles to a porous fabric
collecting surface.  Since the collection surface is porous, a small portion
of the gas stream containing the dust flows through the pores which ensures
that the dust layers remain attached to the collection surface.  Specified
applications for REP include control of fine particulate emissions from
coal-fired utility boilers and, possibly, fine particulate control in
so-called "clean rooms" in which complex electronic and computer circuits are
produced.

On the basis of the pilot plant test conducted in 1990, management concluded
that the test identified additional design parameters which, if adopted,
would improve performance and that the REP concept can be utilized, when
properly developed, to enhance the collection of fine particulates at lower
cost than existing methods.  ETS has not pursued further testing, does not
intend to fund future development and will require future Government or
private funding to continue development.  As the Company's more mature
technologies, such as the BPM and LEC, neared commercial development, the
Company determined that its financial commitment to products should be
concentrated on commercializing and marketing the BPM and LEC.  Although it
continues to seek outside funding sources, ETS has no current proposals
outstanding for further funding.  In the event the question of commercial
viability is successfully resolved, of which there is no guarantee, ETS
intends to secure a licensee to market the REP of which there is no
guarantee.  Even if commercial viability is established to ETS's
satisfaction, it is unlikely that development will be completed and delivery
of orders will commence in the foreseeable future.

Services

Contract Research and Development.  ETS has performed specific research and
development projects for both government and private industry.  These
projects primarily involve the advancement of air pollution control
technology and have included the design and fabrication of pilot plants to
demonstrate certain air pollution control hardware, operation of equipment
within the pilot plants and long-term testing and monitoring of systems.  ETS
has designed, built, operated and tested pilot plants for coal-fired
industrial boiler systems, refuse-fired boilers, cement kilns and glass
furnaces.  These pilot plants have examined, among other things, control of
fly ash, sulfur dioxide and toxic emissions.

For clients such as Dupont, Celanese, Phillips Fibers, Baltimore Gas &
Electric, Serrine, ARCO and General Electric, ETS has performed studies of
alternative filtration.  Studies have ranged from bench top swatch test
programs to pilot plant evaluations, to full scale tests within operating
baghouses utilizing the BPM analysis tools.  Some programs were designed to
evaluate the usability of new fabric offerings in specific applications,
others to provide evaluation of new fabrics as a viable general fabric filter
candidate and others to select the optimum candidate from a group of possible
fabric alternatives in a specific baghouse.  Except for U.S. Government
sponsored research and development, all research and development contracts
have been performed on behalf of customers.
<PAGE>

Fabric Testing Services.  The fabrics used in baghouses to collect dust must
meet certain requirements as to strength, permeability, pressure resistance,
air flow characteristics and chemical content.  ETS offers quality control
and other fabric testing services to the fabric filtration industry to
determine whether baghouse fabrics meet these standards.

Stack Testing and Other Field Services.  ETS offers analyses of particulate
and gaseous emissions for evaluating the performance of pollution control
devices and statutory compliance.  Customers include both government and
private industry.  Testing has been undertaken at steel plants, cement
factories, quarries, foundries, incinerators, chemical plants and utilities. 
To assist in supplying these services, ETS has five mobile field testing
laboratories for on-site testing and analysis.

Other field services include continuous emission monitor certification,
asbestos surveys, environmental audits, analysis and evaluation of on-line
systems, filter bag analysis of operating systems through on-site and
laboratory examinations, evaluation of bags for use in particulate filtration
systems, new filter media inspection and testing, compliance with emissions
standards, on-site and laboratory particle size analysis and OSHA in-plant
air quality testing.  This service is appropriate for compliance with Title
III of the CAAA involving Air Toxics because compliance requires
sophisticated field and laboratory capability.  Title IV of the 1990 CAAA
requires the annual testing of 2,000 utility continuous emissions systems.
ETS has become a major vendor for this service.

Major clients, on a continuing basis, for ETS's field service activities
include Westinghouse, Philip Morris, DuPont, Air and Water Technologies,
Allied Chemical, Duke Power, Sun Oil Company, Tennessee Valley Authority and
Baltimore Gas & Electric.

Regulatory Assistance.  ETS offers its industrial clients which operate
facilities subject to state and federal environmental regulations
professional assistance in understanding relevant environmental regulations. 
Many environmental regulations are complicated, apply only to certain types
of operations and not to others and change in their scope and content from
time to time.  They are written by technical personnel employed by the
regulatory agencies in order to fulfill legal requirements of the relevant
laws and statutes promulgated thereunder.  ETS staff consists of technically
trained people who maintain a current knowledge of these environmental
regulations and are also familiar with clients' plant operations.  Thus, ETS
can provide clients specific interpretations of regulations and assist in
establishing the most effective route to demonstrate or achieve compliance
with specific requirements.  The CAAA, particularly Title V regulating
permitting, has had a positive effect on demand for ETS's regulatory
assistance services.  ETS does not employ an attorney on a regular basis in
rendering its regulatory assistance services; but has available specialized
counsel on an as-needed basis.  ETS recommends that its clients seek
independent legal counsel to address legal issues, including but not limited
to past noncompliance with environmental regulations.  In addition, ETS often
works with the clients' legal counsel in resolving issues of noncompliance
with federal and state environmental regulations.
<PAGE>
Monitoring.  Federal and state environmental protection agencies are
increasingly requiring self-monitoring by industry. Monitoring activities
involve either direct measurement of pollutants emitted in the stack gases or
measurement of pollutant concentrations in ambient air at or beyond the
plant's fence line.  Both measurements involve the collection of large
quantities of data using sensitive continuous monitoring systems.  ETS
assists in designing, calibrating and auditing the monitoring systems and in
preparing periodic reports and summaries of the data obtained. 

Consulting.  The consulting aspect of ETS's business is diverse.  Included
are expert testimony, pollution control equipment operational problem
solving, review of plant specifications, market analysis recommendations,
license evaluation and acquisition analysis.

Technical Services.  ETS has performed technical and economical evaluations
of existing and proposed air pollution control systems.  It provides air
pollution control system design and on-site services during system erection
and start up.  ETS also provides advice on emission control system design,
specifications, bid evaluation, and air pollution control systems trouble
shooting and maintenance as well as operator training.

Training and Education.  ETS regularly offers several in-depth seminars in
the fields of air pollution control design and regulatory assistance,
incinerator emissions control, fabric filtration and electrostatic
precipitation.  It also has produced a cassette tape seminar.  Although
training and education constitute only a minor portion of ETS's business,
ETSI believes that its involvement in this area allows industry participants
to become familiar with its products and services.  In total, in excess of
1,000 industry representatives have attended ETS seminars since their
inception.  The seminars resulted in numerous clients for other services
offered by ETSI.  ETS has a continuous and comprehensive seminar program
servicing industry and government.  Recent seminars have been conducted in
Canada, Brazil, Egypt, India and Turkey in addition to those held in the
United States.  

Technical Writing.  ETS's technical writing staff is experienced in all areas
of air and water pollution control and is proficient at the art of relating
technical data in a readily understandable manner.  Other capabilities
include research, graphics layout and design and proofreading.  

Literature Searches.  Under contract with both government and industry, ETS
has successfully conducted extensive literature searches in the area of
particulate and sulfur dioxide control.  ETS maintains an extensive and
well-cataloged in-house library and, when required, employs outside library
services.  

It is anticipated that the service business will continue with additional
expansion of revenues from areas such as engineering, field testing and
regulatory assistance.  ETSI intends to continue to explore foreign market
opportunities for ETS's products, particularly in Taiwan, Canada, Brazil,
Korea, Egypt, India and China to focus on marketing the BPM system and more
actively to pursue licensing of the Dry Reactor and Limestone Emission
Control System.  In addition, the stricter enforcement of the CAAA, if it is
implemented, would result in increased activities in both laboratory
analysis, field testing, baghouse monitoring and other aspects of ETS and
ETSAS' business.  There can be no assurance of stricter enforcement of the
CAAA.

Patents, Licenses And Trademarks

ETS currently holds various U. S. patents and licenses covering certain
aspects of its proprietary products that it considers material to present
sales and further development and marketing of such products.

Features of the Dry Reactor involve a process subject to U. S. Patent No.
4,273,750, expiring in 1998, the rights to which were acquired by ETS in
1982.

ETS is the assignee of U.S. Patent No. 4,663,136, issued to Dale A. Furlong
on May 5, 1987, for an invention which is the process basis of the LEC.  ETS
was also assigned another patent on another apparatus utilized in the sulfur
dioxide and particulate removal process (U.S. Patent No. 4,764,348) which was
issued to Dale A. Furlong on August 10, 1988.  That patent is the basis of
European patents issued to ETS.

ETS owns two additional patents relating to the LEC. Aspects of the LEC are
also covered by U.S. Patent 4,663,136 and European patents based on it.
Management of ETS believes that the patents relating to the LEC will protect
it from infringing use.  On April 29, 1997, ETS was granted U.S. Patent No.
5,624,644 covering the equipment design aspect of the LEC.

ETS holds U.S. Patent No. 4,481,017, issued to Dale A. Furlong and assigned
upon issuance to ETS, covering the combination of the electrostatic
precipitator and fabric filtration technologies used in the REP.  This patent
was issued on November 6, 1984.

ETS holds U.S. Patent No. 4,719,791, which relates to the BPM system and
claims protection for several unique aspects of the system.  This patent was
issued on January 17, 1988 and assigned to ETS. 

ETS has acquired the non-exclusive license to utilize U. S. Patent No.
4,297,113, which provides a method for eliminating the effect of bag failure
on baghouse operations.  ETSI has no specific plans for the use of such
patent.  The license is nonassignable and will lapse upon termination of John
D. McKenna's employment with ETSI.

ETS Analytical Services, Inc.

ETSAS maintains extensive laboratory facilities and modern mostly automated
and computerized equipment to detect other types of environmental
contamination.  It has established a stringent Quality Assurance/Quality
Control ("QA/QC") Program to insure data reliability.  Although at the end of
the 1995 fiscal year, ETSW was a Superfund Contract Laboratory, its status as
a Superfund Laboratory had not been renewed due to lack of funding for the
program.  It continues, however, to receive contracts from the United States
Environmental Protection Agency ("USEPA") and other governmental agencies. 
ETSAS is also a certified laboratory in the states of Virginia and in North
Carolina for water, waste water, soil and hazardous waste analysis.  In
addition to its laboratory operations, ETSAS offers a wide range of field
services, including sampling of water and soil, infield testing and on-site
monitoring, environmental assessment and monitoring programs.  ETSAS owns a
mobile laboratory which provides on-site analysis for trace organic
compounds.  In January, 1995, Environmental Laboratories, Inc., a Richmond
Virginia - based company, founded in 1980, engaged in water, wastewater, soil
and materials analysis, was merged into ETSAS.  This additional operation is
located in the same city as ETSW.  The merger expands the geographic range of
<PAGE>

ETSAS, enables the Richmond operation to bid on larger and more complex
contracts than it could support prior to the merger and facilitates a closer
working relationship with ETSW.  The acquisition of environmental laboratory
assets located in Fairfax, Virginia enhances the ability of ETSAS to bid on
projects in Northern Virginia.  ETSAS has opened a satellite lab in
Chesapeake, Virginia in order to better serve its clients in the Chesapeake-
Norfolk area.

ETSAS's analytical services include obtaining and isolating samples of
industrial and other waste materials including potentially hazardous wastes,
analyzing samples by identifying and quantifying their toxic components,
electronically archiving data and the delivery of analytical data in a
legally defensible manner.  ETSAS's analyses are used by regulatory
authorities, such as the USEPA and the City of Roanoke, Virginia, and site
owners, such as Exxon, Union Carbide and Columbia Gas Transmission, to report
the risks posed by the potential or actual presence or release of hazardous
substances.

ETSAS performs analyses of waste materials to determine the chemical
compounds present, organizes the data obtained and presents a comprehensive
report of this data.  There may be myriad potentially harmful chemical
compounds present in wastes and multiple tests may be required to determine
the levels of contaminants at even a single site.  Results obtained indicate
only the amount of contaminant at the time of the test.  To assess the
probability of future hazards or the degree of correction of the pollutants
also requires several tests at relatively constant intervals.  There is also
the possibility that the hazardous waste may have migrated from its initial
site.  Additional analysis and remedial action away from the original test
site may be required where the migration of hazardous waste is a possibility.

Samples of the material to be tested are taken by either ETSAS's clients or
its own personnel and forwarded to the laboratory for analysis.  ETSAS is
required to establish the authenticity of the test samples and therefore each
container supplied by clients is accompanied by its chain of custody form.  
ETSAS's technical staff utilizes mobile sampling equipment for the sampling
and testing of hazardous waste sites, monitoring wells or industrial
discharges.

Sample Management.  All incoming samples, whether they are shipped via
courier service or dropped off by local customers, are received by this
section and logged into the ETSAS Laboratory Information Management System
("LIMS") which tracks analyses and reports laboratory data.  The ETSAS LIMS
is an internally developed software system that has received wide recognition
from industry and government.  The Sample Custodian is responsible for all
receiving, storaging, and tracking functions.  All samples must be signed out
by laboratory analysts for processing, thus maintaining a complete chain of
custody within ETSAS.

Atomic Spectroscopy ("AS").  The Atomic Spectroscopy section analyzes all
samples requiring elemental analysis by atomic spectroscopy.  Among the
techniques the AS section employs are the following:

Graphite Furnace AAS determines low levels of toxic elements such as arsenic,
selenium, and thallium.  It can detect and quantify levels less than 1 part
per billion.

Cold Vapor Mercury AAS tests for low level mercury analysis (0.2 parts per
billion in water) in a variety of sample types.
<PAGE>
Air Analysis of multi-metal air trains by Microwave Digestion and AAS
techniques.  Analysis of metals and elements by Inductively Coupled Plasma
Emission ("ICP").

Organics. The Organics section provides laboratory services relating to the
detection and measurement of various organic substances in a variety of
sample types, such as groundwater, RCRA sludges, tissue, oils/waste oils, and
others.  Examples of these include pesticide, herbicide, and fungicide
residues such as chlordane, endrin, toxaphene, silvex, and Ethylene Dibromide
("EDB").  ETSI can detect PCBs (polychlorinated biphenyls) in dielectric
fluids, oils, waste oils, wastewater, and soils, performs high pressure
liquid chromatography for the analysis of explosives and other high molecular
compounds, detects total organic halide ("TOX") and purgable organic halide
("POX") in groundwater and other liquid media; total organic carbon ("TOC")
and purgable organic carbon ("POC") in aqueous samples.  It "fingerprints" by
gas chromatography to identify unknowns and finds benzene, toluene,
ethylbenzene, xylenes ("BTEX") in groundwater by gas chromatography and
photoionization detector ("PID").  Finally it performs analyses of trace
organics by gas chromatography and mass spectrometer ("GC/MS") for volatile
organic compounds ("VOA" or "VOC") and semi-volatile organic compounds in
accounts with certain ETA methods.

Inductively Coupled Plasma Laboratory.  ICP laboratory is used for rapid
analysis of metals/elements.  The ICP laboratory is fully automated and
computerized and is capable of analyzing up to 69 elements per sample in
approximately 5 minutes.  Much of the analysis on the USEPA Superfund and
Office of Water contracts is performed on this instrument.  Raw data is
transferred into the ETSAS LIMS for processing and reporting.  The ICP
laboratory uses "SuperScan," a low cost qualitative scan developed by ETSI
for 69 elements per sample.

Gas Chromatograph/Mass Spectrometry ("GC/MS") involves a three-step process. 
First, a test sample is introduced into the gas chromatograph portion of the
system which separates the individual chemical compounds.  The separated
compound then elutes into the mass spectrometer are often subject to multiple
regulatory requirements.

Quality Assurance/Quality Control.  ETSAS maintains an ongoing QA/QC Program
that is designed to give data of the highest documented quality.  The QA/QC
Program is a continuing system of internal and external checks of data
validity.  The entire program is contained in a 150 page manual which is
available to clients upon request.

ETSAS maintains strict quality control in all facets of testing and analysis
to insure accuracy of results.  Internal quality assurance procedures,
formulated within USEPA guidelines, govern how samples and controls are
handled and are monitored daily.  Standards are used to calibrate the
equipment on a daily basis.  Samples are periodically issued by both the
quality control manager and various federal, state and local certifying
licensing agencies, to determine whether test results from samples furnished
by the agencies fall within acceptable limits.

ETS and ETSAS maintain a network of more than 30 computers for sample log-in,
sample tracking, data handling, data reporting and accounting activities. 
The computers are linked together through a Novell Netware System, and many
of the analytical instruments are on-line to this system which allows for
computerized raw data transfer.  Data reporting can therefore be customized
to a clients individual needs, including the reporting of quality assurance. 
The total hard disk data storage capacity of the Novell system exceeds one
gigabyte.

See discussion under "Completion of Contracts by Subsidiaries of ETSI" below.

Sales And Marketing

ETS and ETSAS presently market their services through their sales personnel,
and utilize direct mail, trade exhibitions and promotional literature. 
75-90% of their revenues are realized from commercial clients and 10-25% from
the USEPA and other government agencies.  However, this ratio is anticipated
to change as a result of the receipt by ETS and ETSAS of awards of U.S.
Government contracts under the CAAA.  ETS's extensive sponsorship of seminars
and training programs has resulted in recognition and has secured clients. 
ETS is negotiating with major industry partners for the development,
licensing and sale of its products.  ETS has entered into license agreements
for several of its products.  ETS has begun receiving license fees, but there
is no assurance that substantial license fees will be received in the future.

Representative Clients

Clients of ETS and ETSAS represent the following industries: power generation
(utilities), petrochemical, chemical, tobacco, iron and steel, non-ferrous
metals, gas utilities, heavy manufacturing, engineering, government agent
contractors, municipalities and regional and federal government agencies. 
Representative clients are those in the industrial segments to which ETS and
ETSAS supplies services.  Such clients of ETS and ETSAS include: Kentucky
Power Company and Pennsylvania Power & Light (power generation), EXXON
(petrochemical), Dupont and National Paint and Coating (chemical), Philip
Morris (tobacco), Inland Steel (iron and steel), Reynolds Metals (non-ferrous
metals), Columbia Gas (gas utilities), Westinghouse (heavy manufacturing),
Dames & Moore (engineering), Draper Aden (environmental engineering
consulting); Smith Environmental (environmental engineering); Phillips
Environmental (environmental engineering); Ironton Iron (iron foundry); KVB
(government agency contractors), County of Roanoke, City of Richmond
(municipalities) and USEPA (regional and federal government agencies).

Competition

Although the pollution control industry in general is growing rapidly,
competition is intense.  Marketing resources and expertise are increasingly
important to success.  In addition, the pollution control markets are subject
to rapid change.  Unforeseen technological, legislative and business
developments relating to pollution control outside the scope of ETS and
ETSAS' business may have significant adverse effects upon ETS and ETSAS'
business.  Many of ETS and ETSAS' competitors have substantially greater
resources than ETSI, and the size and reputation of many of these companies
may give them a competitive advantage over ETSI.  However, ETSI has
successfully competed for USEPA contracts against large firms such as General
Electric Company and Bechtel Power Corporation.  Likewise, ETSI has won
utility contracts in competition with firms as Research Cottrell, Inc. and
Gilbert Commonwealth Engineering.
<PAGE>
Major competition for the LEC and Dry Reactor markets come from the U.S.,
Japan and Europe.  In the U.S., primary competitors include Babcock and
Wilcox, General Electric Environmental Service and Research Cottrell. 
Foreign competitors include Chiyoda, Hatachi-Zosen, Mitsui and Fuyikasui
Engineering Co. from Japan and Lurgi, Flakt/ABB, Steinmuller, FLS Miljo,
Snamproqette and Tampella from Europe.  Most of these companies offer both
semi-dry and wet systems.  However, it is management's opinion that the LEC
is the lowest cost, most efficient acid gas removal system.

ETSI is aware of at least two companies that are developing smokestack
chemical removal products which reduce nitrous, as well as sulfur, oxides
which are removed by ETS's LEC process.  In management's opinion, the ETSI's
LEC device is smaller, less complex, simpler to operate and easier to
retrofit than one of the competing products and has a lower waste disposal
cost and its waste is nonhazardous compared to the second competing process. 

In the event the REP technology is developed so that a commercial product
results, the REP's competition is expected to come from the major suppliers
of precipitators and baghouses.  The REP, as proposed, has no present direct
competition as no other firm presently offers a combination of electrostatic
and filtration technologies.  However, it may be possible for competitors to
develop technologies to achieve the same end.  

ETS is presently not aware of any competitors offering products directly
competitive with the BPM.

ETS also has competition in every area of its service market.  The stack
testing service market is sensitive to location.  Over one hundred companies
offer such services in the United States.  The top four companies are
believed to be Entropy (North Carolina), Clean Air Engineering (Chicago,
Pittsburgh, St. Louis), Mullins (Texas) and Engineering Science (North
Carolina).  

Fabric testing presents a smaller market, in which location is less
important.  ETS has a well - equipped independent testing laboratory.  The
majority of customers of the fabric testing market is shared by fewer than
six firms, including Filter Lab Services, Environmental Consulting Company
and Grubb Filtration.

Competition for analytical laboratory services comes from local concerns for
regional business.   National and government services require more
sophisticated analytical techniques for which many laboratories lack
equipment and personnel.  The USEPA has indicated that it will institute a
national certification program.  If and when it does, management believes
that many competing firms may leave this aspect of the business.

ETS competes with universities, equipment manufacturers and other consultants
in the area of contract research and development.  ETSI believes that the key
criteria considered by potential purchasers of its services and products are
service and product quality, the quality of support, the consistency of
marketing and promotion programs, the financial stability of ETSI and
pricing. 
<PAGE>

Government Regulation

The USEPA is the principal federal agency responsible for environmental
matters, including the disposal and discharge of hazardous substances.  State
and local governments are involved in implementing environmental programs on
a state and local level.  USEPA, state and local policies can adversely
affect the demand for ETS and ETSAS' services by relaxing regulations
requiring tests, by delaying the effective date of regulations which require
tests and by relaxing its enforcement efforts.  Furthermore, to the extent
that the budgets of administrating agencies are reduced, or funds are not
made available to them, the demand for ETS and ETSAS' services can also be
adversely affected.  Applicable federal legislation includes the Resource
Conservation Recovery Act ("RCRA"), the Clean Water Act, the Safe Drinking
Water Act, the Clean Air Act and amendments, the Toxic Substances Control
Act, the Comprehensive Environmental Response Compensation and Liability Act
("CERCLA"), and the Superfund Amendments and Reauthorization Act of 1986
("SARA"), which authorized the appropriation of $8.5 billion for Superfund
for the five-year period beginning October 17, 1986 and was refunded in 1990
for an additional five years for $5.1 billion.  Funding for SARA was not
renewed at the termination of the extension of the act.  ETSAS suffered some
loss of revenue as a result.  However, the laboratory has diversified into
serving industrial and commercial clients and receives Federal contracts
which were not funded through SARA.

ETSAS generates small quantities of hazardous waste in processing, certain
samples.  Such hazardous waste is segregated in special containers and
disposed of by licensed waste transporters.  ETSAS reserves the right to
return the unused portions of samples received.  ETSAS is also licensed with
the USEPA and the State of Virginia to generate and properly store small
quantities of hazardous waste.  Such waste may not be stored longer than six
months and must be disposed of through a licensed hazardous waste transporter
to an approved treatment/disposal site.  ETSI believes that its operations
have at all times been in compliance with all federal, state and local
environmental laws and regulations.  ETSW, in its remediation projects, often
removes hazardous waste.

ETS and ETSAS' activities and its facilities are subject to regulation under
federal, state and local laws, ordinances and rules and regulations relating
to the environment, environmental quality and occupational health and safety
including RCRA, the federal Occupational Safety and Health Act ("OSHA") and
similar state laws and regulations promulgated thereunder.  In connection
with ETSAS's business of waste analysis and management, ETSAS believes it is
acting in compliance with applicable environmental laws.

ETSI has obtained certifications from all jurisdictions in which it does
business as required to conduct its laboratory testing.  ETSAS is required to
pass proficiency tests and evaluations which are given on a periodic basis to
retain its certification and to participate in contracts under the Superfund
Program.  ETSAS has never failed a proficiency test and believes, but there
can be no assurances, that it will be able to obtain the required
certifications and approvals in all jurisdictions where it plans to do
business in the future.  The inability of ETSI to retain present, or obtain
new, certifications or approvals where required, would adversely affect its
business.
<PAGE>
Markets

ETSI has targeted utilities, industrial boilers and incinerators as the most
likely users of its air pollution control equipment.  Customers for air
pollution control services and equipment include any organizations which
operate a process that emits pollutants.  Examples of potential customers
include industries that utilize burning processes such as coal-fired utility
and industrial boilers, incinerators for hazardous and municipal wastes,
chemical processes such as printing, paint manufacturing, petrochemical
refining and production, pulp and paper making and dust creating processes
such as cement manufacture, mining and grain handling.  In addition,
governmental agencies are purchasers of the products and services of ETSI. 
The utility industry and users of municipal and hazardous waste incinerators
and resource recovery facilities comprise ETS's principal potential
customers.

Customers for analytical laboratory services include local concerns,
government agencies, resource recovery facilities and national companies. 
ETSAS contacts potential clients through advertising, direct mail and
telephone and competitive bid. 

Employees

ETS and ETSAS have a total of approximately 17 management and supervisory, 55
field and technical and 17 administrative employees.  Employees are not
represented by labor unions and relations are considered good.

Insurance

ETSI, for itself and its subsidiaries, ETS and ETSAS, currently carries
general liability insurance with an aggregate limit of $1,000,000, and
automobile liability insurance with $1,000,000 for each occurrence and 
professional liability insurance of $1,000,000.  It also carries excess 
liability insurance of $1,000,000, as well as workers' compensation and 
liability insurance in statutory amounts.  

ETS Water & Waste Management, Inc.

History and Overview

Stamie E. Lyttle Co., Inc. was established by Stamie Lyttle in 1947 as a
partnership originally known as Lyttle & Barnes.  With two employees, it
installed septic systems for new homes.  In succeeding years, it expanded
into other related environmental and construction areas.  Lyttle Utilities,
Inc. was formed in 1982.  Lyttle Utilities, Inc. contracted water and sewer
installations for municipalities, while Stamie E. Lyttle Co., Inc.
concentrated on residential construction.  In 1985, LPS Corp. was formed as a
leasing company for the affiliated companies.  Stamie E. Lyttle Co. Inc.,
Lyttle Utilities, Inc. and LPS Corp. were merged in June, 1994 into ETSW, a
subsidiary of ETSI.  Business previously conducted individually by the three
companies is now conducted by ETSW under the trade name "Stamie E. Lyttle
Company."  ETSW provides infrastructure services to municipalities throughout
the Commonwealth of Virginia, including the state government, encompassing
installation of water, sewer and storm sewer mains, installation of gas lines
and environmental clean-up.  For the private sector, ETSW provides services
to industrial, commercial and residential developers.  Industrial and
commercial services include installation of and disposal of nonhazardous
waste.  Residential services include hookup of development projects to
<PAGE>
municipal water and waste disposal systems. ETSW also operates ETSL under 
the trade name "Pipe-Liner Installers." Pipe-Liner Installers is primarily
involved in the trenchless rehabilitation of sewer and water lines under 
a license from Ultraliner, Inc. ("Ultraliner") covering most of the State 
of Florida.  ETSW also has a license from Ultraliner covering Northern 
Virginia.  ETSW also has agreed to be a licensee with TRS, Limited, Canada, 
for pipe bursting technology for Virginia, Maryland and Florida.

Municipal Activities

Municipalities, particularly in the area surrounding Richmond, Virginia
traditionally serviced by ETSW, have been growing at an annualized rate of
approximately 5%.  This growth has strained the ability of towns and counties
to deliver water to its industrial and residential base and to handle waste. 
In addition, these same municipalities have had to upgrade their decaying and
inefficient water and waste handling systems though construction, remediation
and clean-up.  The process of installing and upgrading water and waste
disposal facilities is continuous because of on-going population and
industrial growth, aging infrastructure and compliance with federal and state
environmental regulations.

In order to bid for municipal water, sewer and storm sewer main contracts,
ETSW must "prequalify" for each job (as in the City of Richmond) or annually
prequalify for each community which it serves.  Prequalification requirements
include a proven track record of successfully completing similar projects,
necessary manpower and equipment to commence and complete the project and
bonding capacity to support the technical and manpower needs.  The bond
required is a "performance and payment bond" issued by a surety company based
on contractor competence and financial backing.  ETSW has successfully
prequalified for every job for which it has bid and is prequalified by all
the municipalities in which it works.

Municipalities and the state governments must, by law, advertise in local
newspapers and public bulletin boards and through the Dodge Report.  The
Dodge Report is distributed weekly to subscribers and contains all material
information on municipal construction projects, including description, scope
of work, requirements for the contractor, estimated amount of bid and
availability of plans and specifications, thus enabling contractors to decide
which projects to pursue and to formulate bids.  ETSW not only bids on the
basis of the specifications contained in the Dodge Report, but is also often
invited by the municipalities themselves to bid on specific projects.  ETSW
selects the projects that it desires to bid based on its computer analyses of
present and future work requirements and its anticipation of profitability of
the project based on the cost of past similar projects.  It then prepares and
submits bids on appropriate projects.  Bidding is generally closed.  Bids are
opened in a public place and the low qualified bidder is awarded the
contract.  In some instances, specifically projects for the City of Richmond,
Virginia and the Commonwealth of Virginia, minority participation is required
to complete the project and is set forth in the requirements and in the bid. 
Because of its size and experience, ETSW has developed an excellent
relationship with qualified minority contractors who ably perform their tasks
as part of the contracting team.  

The municipality notifies the low bidder contract awards in writing, stating
the time frame in which the project must be completed.  If ETSW is the low
bidder, ETSW must submit a profile called the "Critical Path Method" or "CPM"
setting forth the time frame in which it intends to complete the project so
that the designated representative of the municipality can follow the project
as outlined in the CPM.  Projects generally run in phases with progress
billing on a monthly basis until completion.

City of Richmond, awarded September, 1995, estimated completion in October,
1997 represents construction of a concrete drainage channel and the
reconstruction of a storm drain system and related work.  Total award is
approximately $1,900,000.

York County, awarded June, 1995, involved installation of 16" water;
completed in February, 1996.  Total award was $625,000.

County of Henrico, awarded in August, 1996 is a contract valued at $268,696
to furnish two water lines.  Completion is expected in October, 1996

VDOT, awarded July, 1997, is a contract valued at $1,168,492 for the
installation of water and gas main lines.  Completion is expected by June 30,
1998.  

Commercial Construction

ETSW performs services for developers, corporations and homeowners.  For
residential and commercial developers, ETSW provides the interface between
the developer and the local zoning authorities for site development plan,
sewer and water main hookup and soil conditions.  For commercial and
industrial customers, ETSW provides the technical expertise required to
maintain the plant conditions in an environmentally safe fashion.  For
example, a factory or office building owner often will establish its own
sewer system but will later discover that the installation does not meet the
needs for adequate holding tank capacity.  ETSW, in such a situation, will
design and modify the equipment to meet legal and environment requirements. 
It also maintains such equipment.   

Thus, it can uniquely provide reliable and timely service without the
problems of job overload which afflict smaller competitive firms.  ETSW was
often the original installer of the equipment for the developer and maintains
records of each facility indefinitely and thus knows which equipment was
installed and when so that it can often assess problems before arrival of its
employees on site.

Typical ETSW Commercial Projects

The following is representative of commercial projects undertaken by ETSW:

Stonehouse, Inc., a wholly-owned subsidiary of Chesapeake Corporation,
involved the installation of 36" water line; this contract was the first
phase of a 20-year development project.  The first phase was successfully
completed in March, 1996.  Total contract amount was $770,000.

In December, 1996, ETSW was awarded a major contract with DPR Construction
Corporation for construction of water and sanitary server lines at The White
Oak Semiconductor facility in Henrico County, Virginia for $1,800,000, which
was subsequently increased to $3,600,000 with an expected completion date of
October 1997.

Ultraliner

In February, 1996, ETSI acquired certain assets of Olympic Industries, Inc.,
Pompano Beach, Florida, for 539,130 Shares of Common Stock.  The assets were
placed in a newly-formed corporation, ETSL, a Virginia corporation, and a
wholly-owned subsidiary of ETSW. 
<PAGE>
Through the purchase of these assets, ETSW entered the trenchless
rehabilitation business throughout Florida (except the "Panhandle" area) and
in Northern Virginia.  ETSW believes that the trenchless rehabilitation
market will be a major growth area as the sewer and water lines in most urban
areas throughout the world are wearing out.  Over time, pipes get old and
brittle causing breaks which lead inevitably to water leaks and the seepage
of ground water into the pipes.  In many cases, roots grow into pipes and
entire sections of pipe are frequently missing.  

The traditional method of repairing such pipe is by digging a trench above
the pipe, removing the old pipe and replacing it with new pipe.  The cost and
time spent in avoiding environmental damage is great; and the disruption
caused by digging up the old damaged lines and replacing them can be major. 
Since most older pipe is found in downtown areas, the adverse effects on
traffic, air quality and the creation of ear splitting noise from jack
hammers and earth moving equipment are exacerbated by the surrounding foot
and vehicular traffic.

The "Ultraliner" technology used by ETSW and ETSL is expected to permit
rehabilitation of such lines on a faster, cheaper and cleaner basis without
the necessity of digging trenches.  First, a robotic vehicle with lights and
video cameras traverses the damaged lines to detect blockage, offset joints
or other impediments.  Then, any remedial work is performed within the
existing lines either through a point repair from the surface or through a
remote device.  Installation of Ultraliner requires only one insertion point. 
At the job site, liner which is constructed specifically for the job and
which is folded to fit within the existing sewer or water line is inserted so
that it extends through the damaged length.  The length of each pipe is at
least the distance from manhole to manhole.  Insertion is made with a power
winch and steel cable connected to the end of the liner.  Then, through
application of heat and pressure, the liner expands to fit within the
existing line.  The fit is so tight that it leaves no annular space for
unwanted water migration between the Ultraliner and the old pipe.  The new
smooth interior maintains peak flow and inhibits buildup of foreign material. 
The life of the replacement liner is the same as new pipe.   

ETSL has been awarded a contract with an estimated value of $650,000 by the
City of Fort Lauderdale to install 8" Ultraliner for rehabilitation of old
sewer lines.  Installation under the contract commenced in March, 1996;
estimated completion in September, 1996.  The City of Orlando has awarded ETS
Liner, Inc. a one-year maintenance contract with a value up to $500,000.

In October, 1996, ETSW received over $2.3 millon in new contracts, on which
work commenced in the second quarter of fiscal year 1997.  These contracts
include:  two Ultraliner projects with the County of Henrico which are valued
at a combined total of $455,255 for the installation of 5315 linear feet of
8" Ultraliner PVC alloy TM pipeliner and related repairs and new line work;
additional Ultraliner work totaling $215,000, including a City of Richmond
Demonstration Project; the Little Tomahawk Creek Project awarded by the
County of Chesterfield, Virginia for $989,412 to furnish and install
approximately 15,113 Linear Feet of 24, 21, 18, 16, 15 and 10 inch sanitary
sewer; and orders for installation of new water, sewer and irrigation
projects with a combined value of $715,884.

In July, 1997, ETSL received five contracts totaling close to $1,000,000, of
four of which contracts required the Ultraliner to be used for storm lines
and sanitary sewer repairs in the cities of Ft. Lauderdale, Hollywood and
Orlando, Florida and the Hurlhurt Air Force Base in Cocoa, Florida.  ETSL's
slipliner will be implemented for use in the replacement of sewer lines in
Melbourne, Florida.  
<PAGE>
ETSW has successfully completed two demonstration projects in Virginia.  The
first one was in Fairfax County, Virginia, in November, 1995 of lining 1,438
linear feet of existing eight inch concrete sewer pipe, including
reinstatement of 22 sewer services for existing homes, which was witnessed by
personnel from the engineering community and municipalities from the Richmond
and Northern Virginia areas.  The other project is located in Stafford
County, Virginia involving the lining of 390 linear feet of eight inch sewer
pipe and the reinstatement of five sewer laterals which was completed in
June, 1996.  Although both of these projects were small, they demonstrated
both the effectiveness of the Ultraliner technology and the ability of ETSW
to implement the technology.  During the first part of fiscal 1997, ETSL
encountered some minor technical problems associated with new materials from
the manufacturer, which materials were experimental.  However, with
improvement of the product, ETSL currently believes that the technical
problems have been resolved.  

ETSW Future Plans

ETSW began in the Spring of 1995 and continued in fiscal 1997 to expand the
services it offers into Northern and Western Virginia in the areas of
plumbing, sprinkler irrigation and fencing.  ETSW also has begun to bid for
projects through Virginia and into Maryland and New Jersey.  It plans to
increase its geographical reach through steady and organized growth. 

ETSW has begun to tap the growth of Northern Virginia by providing similar
municipal services there as it does in the Richmond area.  In April, 1994, it
opened an office in Fairfax, Virginia, from which it is bidding on municipal
construction projects.  It was awarded a major contract with the Fairfax
County Water Authority as a subcontractor to Branch Highways which is
presently under construction.  It desires to acquire companies in similar
businesses, although no such acquisition candidates have been located and
there is no assurance that any will be found.  ETSW intends to focus on
commercial construction projects and on projects involving the Ultraliner
technology or other technology-based construction techniques.

ETSW is working with ETS and ETSAS to provide turnkey construction projects
utilizing its construction expertise and ETS's LEC and Dry Reactor
technologies and ETSAS's chemical and water analyses of pollutants.  The
advantage of proposed joint ventures with the other ETSI subsidiaries is that
previously ETS could only offer its technologies on a royalty only basis,
whereas with ETSW it can now offer both the technology and the construction
of devices employing a given technology or clean up of environmental
problems.  Thus, ETS need not market its technologies through contractors,
but directly to end-users, specifically, hospitals for Dry Reactor and
utilities and manufacturing companies for the LEC system.

ETSW Personnel

In fiscal 1997, ETSW had approximately 160 employees, 30 in residential
service, 100 in construction and 30 in supervisory and administration
service.  ETSW employees are not represented by any union.  Management
considers its relationship with its employees to be good.  Some of its
personnel are third generation employees. 

ETSW Insurance

ETSW carries $2,000,000 of general liability, $1,000,000 of product
liability, $1,000,000 per occurrence of bodily injury and automobile and a
$5,000,000 umbrella insurance policy.  ETSW also is covered by a surety bond.
<PAGE>
ETSW Government Regulation

ETSW's activities are regulated by Federal and state statutes.  In general,
Federal statutes are enforced on the state level by the Virginia Department
of Labor and Safety for OSHA safety standards and by the Department of Health
or Department of Public Works for sewer, septic and water systems.  ETSW has
never been cited for a safety violation.

ETSW Competition

ETSW's competition comes from many smaller and narrowly focused companies in
its geographical region.  ETSW's market share of each of its business
activities exceeds 50% in the Richmond, Virginia area.  In the trenchless
sewer and water main rehabilitation business, its major competitor is
Insituform, Inc.  ETSW believes that its technology is superior and that it
can underbid Instituform on projects and still provide adequate margins. 
However, Insituform has been completing projects for municipalities for over
a decade and Ultraliner must first prove itself to municipalities through
successful completion of small contracts before it could be chosen on larger
programs.  Progress in these areas has been achieved in fiscal 1997.

Completion of Contracts by Subsidiaries of ETSI

Most of ETSI's subsidiaries' contracts are of a short-term duration and are
completed within a few months of the order or award.  Certain contracts, such
as those from utilities, are annual and are completed in stages against task
orders.  Government agencies often issue open orders for which task orders
are issued.  There are no conditions precedent to the issuance of task
orders, and they are issued pursuant to the specific orders of the client for
the services.  The Company's backlog consists of contracts and task orders,
already given but not yet completed and does not include open orders which
may or may not result in task orders.  In general, it has been ETSI's
experience over the past three fiscal years that substantially all open
orders ultimately result in task orders.  Task orders have, from time to
time, exceeded the amount of open orders due to needs of the client which
developed subsequent to the contract date.  However, the dates when open
orders result in task orders, subject to the length of the contract and the
possibility that certain open orders will not result in task orders, depends
on both the needs of the client throughout the contract period and, in the
case of federal agencies, the availability of funding.  There can be no
assurance that existing contracts or future contracts containing open orders
will result in task orders covering the entire contractual amounts.  In
addition, ETSI is not aware of any significant unrecognized cost to complete
any open contract. 

Unfavorable weather conditions can cause postponement and delays in executing
contracts, which may adversely affect the profitability of such contracts. 
ETSI's construction activities, in particular, are materially affected by
adverse weather conditions.  

Item 2.     Properties

ETSI occupies approximately 45,000 square feet of office and laboratory space
in a modern commercial building in Roanoke, Virginia, under lease agreements
of its subsidiaries, ETS and ETSAS, effective as of February 1, 1991, which
expire on December 31, 2000, from PDJ Associates, a partnership in which John
D. McKenna, President of ETSI and Roberta Greiner, widow of Gary P. Greiner,
formerly an officer and director of ETSI, are partners.  ETSI believes that
the leases with PDJ Associates are on terms as favorable as those which would
have been available from a non-affiliated third party.
<PAGE>

The analytical capabilities of ETS and ETSAS consist of three entities: a) a
fixed-location state of the art automated and computerized comprehensive
analytical laboratory for the analysis of contaminated air, water and solid
waste samples; b) mobile laboratories which provide the capability for field
analysis of toxic air emissions; and c) a fixed location fabric testing
laboratory which provides specialized filter bag (fabric) testing and
evaluations.  Management believes that the laboratory and office premises are
adequate for ETS and ETSAS' present and anticipated needs.

On June 1, 1994, ETSW entered into a lease of its premises which are owned by
the estate of Stamie E. Lyttle at $10,500 per month for two years.  On June
1, 1997, the lease was renewed for a one-year term with three one-year
renewal options.  11,500 square feet is allocated for office space; 20,000
square feet for warehouse and 10,000 for service and maintenance.  Outside
storage exists for materials storage and for parking of vehicles.  The
premises are located on 13 acres on the south side of Richmond, two miles
from Interstate 95.  ETSW maintains its own fleet of vehicles and equipment. 
The premises and equipment are considered adequate for the needs of ETSW.  In
addition, subsidiaries of ETSI lease regional office and/or laboratory space
in Orlando, Florida, Fairfax, Richmond, Norfolk and Chesapeake, Virginia and
Huntington Valley, Pennsylvania.

Item 3.     Legal Proceedings.

No material legal proceedings are pending to which the Company or any of its
property is subject, nor to the knowledge of the Company are any such legal
proceedings threatened.

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

None.

Result of Operations

Introduction

      A few relatively large contracts in any one business segment in any
fiscal year can make any  segment generate relatively large revenues in that
year.  Because disproportionate generation of income has occurred
periodically throughout the existence of ETSI, the Company's strategy has
been to offer a variety of services and maintain a flexible staff capable of
executing different tasks. Services are tied to different markets, such as
new pollution control equipment expenditures by industry, government funding
or legislative enforcement.  In addition, ETSI continually markets its
services through brochures, seminars and attendance to trade shows and
conferences and by telemarketing.  ETSI attempts to increase its business in
the aggregate.  As the United States experiences economic and legislative
cycles, the demand for each of the Company's services fluctuates accordingly. 
Likewise economic cycles in countries such as Taiwan and South Korea can
influence the foreign demand for ETSI's products and services.

      On June 1, 1994, ETSI merged with three related Richmond, Virginia
firms, Stamie E. Lyttle Company, Inc., Lyttle Utilities, Inc. And LPS
corporation, and consolidated them into ETSW, a wholly owned subsidiary of
ETSI.  The combination was effected through the issuance of 2,730,000 shares
of ETSI common stock and has been accounted for as a pooling of interest.  On
January 19, 1995, ETSI merged a Richmond, Virginia firm, Environmental
Laboratories, Inc., with its subsidiary, ETSAS, which increased ETSAS size by
about 50% and makes ETSAS the largest environmental contract laboratory in
the state of Virginia.  This combination was effected through the issuance of
183,600 shares of ETSI common stock and has also been accounted for as a
pooling of interests.  On April 3, 1995, ETSI purchased, through the issuance
of 113,000 shares of ETSI common stock, the assets of Air Compliance, Inc., a
Pennsylvania Corporation, and incorporated these assets into the business of
ETS.  On February 5, 1996, ETSI acquired certain assets of Olympic
Industries, Inc. in exchange for 539,130 shares of ETSI's common stock and
incorporated these assets into a new wholly owned subsidiary of ETSW, ETS
Liner, Inc.  On April 18, 1996, ETSI acquired certain laboratory assets of
Dewberry and Davis, Inc. in exchange of 65,617 shares of ETSI's common stock
and incorporated these assets into ETSAS.  These transactions are discussed
further in Note 2 to the audited consolidated financial statements for the
year ended May 31, 1997 (fiscal 1997").  The transactions are anticipated to
broaden the revenues and asset base of ETSI in coming years. The results of
operations for the fiscal years presented include the pooling of interests
transactions as if they had been consummated at the beginning of the earliest
period presented while purchase transactions are reflected since the date of
acquisition.

      ETSI has divided its revenues into four meaningful categories; (a)
services - encompassing field and analytical testing, regulatory assistance
and monitoring; (b) consulting /engineering - encompassing consulting and
engineering services and educational areas; (c) products; and
(d) construction. 
<PAGE>
                 Fiscal Year 1997 Compared to Fiscal Year 1996

      Revenues for fiscal year 1997 were $24,125,260 compared to $20,539,261
for the year ended May 31, 1996 ("fiscal 1996") for a 17% increase.

      Total testing service revenues were $4,733,727 compared to $5,957,008
for fiscal 1996 for a 20% decrease.  Decreases  were experienced in the stack
field testing, regulatory assistance, monitoring, and the laboratory market
areas during fiscal 1997 mainly due to market dynamics.  Intense competition
and reduce pricing played a role in the reduced revenues, however the primary
factor has been the reduction in the quantity of services contracted out by
industrial clients.  This is largely related to significantly relaxed
environmental enforcement in the geographic area serviced by ETS.  Although
revenues during fiscal 1997 were down from fiscal 1996, income was
significantly increased because of cost reductions that were put into place
at the end of fiscal 1996 and increased margins generated from engineering
services. With the expansion of the engineering service, ETS has several long
term projects that will carry throughout all or most of fiscal year 1998
which includes the proposed China Steel LEC design and installation project,
as well as an air pollution control system upgrade design and an installation
program for a medical waste incineration facility.

      Field testing service revenues for fiscal 1997 were $1,905,206 compared
to $2,356,553 for the prior year for a 19% decrease. Competitive pricing
pressures resulted in reduced stack testing whereas the overall customer base
was broad and consisted primarily of private industries. Major customers
included three municipal waste incinerator plants, a petroleum refinery, an
electric utility power plant and the Department of Defense Government Agency. 
Efforts are underway to increase the business base for stack testing services
to compensate the loss of revenue related to the withdrawal of services from
a fortune 500 company from the municipal waste-to-energy business. 

      Regulatory assistance revenues for fiscal 1997 were $175,688 compared
to $534,889 for fiscal 1996.  Due to an overall weakness in the market and a
significant reduction in enforcement of environmental regulations, regulatory
assistance revenues continued to be very soft as was expected.  The market is
extremely flat, with very little opportunity for new work.  Major customers
for fiscal 1997 included a waste-to-energy facility, an electronic testing
equipment manufacturer, a limestone manufacturer, a railroad company and a
paper manufacturer for 56% of the regulatory assistance revenues.

      Revenues for monitoring services were $91,018 compared to $160,914 for
the prior year for a decrease in revenues of 43% which was mainly due to
decrease in services for a printing company.  The single largest customer
included a chemical plant for ongoing services, accounting for 87% of the
monitoring revenues.

      Revenues for analytical laboratory services were $2,561,815 compared to
$2,904,652 for fiscal 1996 for a 12% decrease. The environmental laboratory
market continued to decline during fiscal 1997 and prices continued to fall. 
The winter season decline in remediation activities was extremely severe and
this, coupled with the general market decline, resulted in a reduction in
revenues from the prior year sales. The major source of revenues for fiscal
1997 continue to be sample analysis of contaminated soils and waters at
remediation sites.  No single area of service significantly changed in terms
of relative proportion, and overall revenues were down in comparison to the
prior fiscal year. The major customers continued to be the USEPA Office of
Water, and several well established remediation and environmental  companies.

      Consulting/engineering revenues, which included the sale of books and
training seminars, for the current year were $665,915 compared to $354,484
for the prior year for a 88% increase.  The consulting portion of these
foregoing revenues were $242,454 compared to $112,033 for fiscal 1996 for an
increase of 116%.  A significant portion of this revenue was derived from
reimbursement of cost expended on contracts with the U.S. Environmental
Protection Agency as a result of the completion of an audit performed on
these contracts.  Revenues for engineering services portion for fiscal 1997
were $353,748 compared to $116,278 for fiscal 1996 for an increase of 204%. 
An increase in sales effort has been placed in the engineering area because
it is believed to be the single most attractive option for increasing sales
to offset the reduction in regulatory assistance and stack testing.  The
single largest customer for engineering services was an iron foundry which
made up 62% of the total engineering revenues.

      In-house projects revenues for fiscal 1997 which consist of sales of
books were $21,219 compared to $38,213 for fiscal 1996.  Seminar revenues
were $48,494 for the current year compared to $87,960 for the prior year. 
The current year seminars included a contract for the development and
performance of an air pollution control technology training  program  in
Brazil  and a stack testing training program for attendees from Singapore.
These seminars represented 70% of the seminar revenues.

      Revenues for products for fiscal 1997 were $64,782 compared to $8,430
for fiscal 1996 for an increase of 668%. This increase include BPM equipment
sold to a bag house supplier for 26% of the total products and a licensing
fee paid by E & C Engineering for licensing agreement associated with the
Limestone Emission Control (LEC) equipment in the amount of $40,000.

      Revenues for construction services for the current year were
$18,660,836 compared to fiscal 1996 revenues of $14,219,339 for a 31%
increase.  The Company showed a substantial increase in revenues and an
increase in income for the current year as a result of an increase in the
construction division with a greater activity in the Richmond, Virginia area
compared to the previous year.  The major customer was DPR Construction,
Inc., the general contractor for the White Oak Semiconductor project.  The
Company expects to replace this work for fiscal 1998 with similar projects. 
The service area revenues remain the same as fiscal 1996 while the irrigation
business was lower than the previous year due to a changed focus from
residential irrigation to commercial irrigation.  The major area of
improvement was the rehabilitation work where the market is getting stronger
and the Company sees the opportunity to increase the overall profit margin.   

      Cost of goods and services were $19,605,497 or 81% of total revenues
for the current year compared to $18,555,761 or 90% of total revenues for the
prior year.  This decrease in cost as a percentage of revenues were due to
1) an effort of cutting cost, 2) an effort to sell contracts that are more
profitable and 3) the reimbursements of approximately $225,000 of cost
expended for engineering service as a result of completion of an audit by EPA
on completed contracts.

      Gross profits for the year were $4,519,763 or 19% of revenues compared
to $1,983,500 or 10% of revenues.  This increase in gross profits reflects
the increase in sales and the lower cost of those sales plus the additional
revenues from the EPA.
<PAGE>
      Selling, general and administrative expenses for fiscal 1997 were
$3,962,353 or 16% of the revenues compared to $3,622,064 or 18% of the fiscal
1996 revenues. This decrease in cost as a percentage of revenues was the
result of controlling cost.

      Interest income from savings on deposit for fiscal 1997 was $20,024
compared to $21,107 for fiscal 1996.  Interest expense for the current year
of $572,829 compared to $392,131 for fiscal 1996.  The increase is due to
interest costs associated with the convertible debentures.  Other income was
$143,830 for fiscal 1997 compared to $10,797 for fiscal 1996 and consisted of
gain on the sale of equipment and scrap. 

      Net income for the current year was $148,435 compared to a loss of
$1,998,791 for fiscal 1996.  In 1997, the construction company experienced a
substantial increase in revenues of $4,441,497 which resulted in net income
of $760,666 which was enough to overcome the substantial loss of $612,231
created by the environmental operations.  In 1996, the construction company
experienced a net loss of $1,370,844 and the environmental operations
experienced a net loss of $627,947.

                 Fiscal Year 1996 Compared To Fiscal Year 1995

      Revenues for fiscal 1996 were $20,539,261 compared to $19,911,906 for
the year ended May 31, 1995 ("fiscal 1995") for a 3% increase.

      Total testing service revenues were $5,957,008 for the current year
compared to 6,122,207 for fiscal 1995 for a 3% decrease.  This decrease was
due to several factors.  The unfavorable weather conditions caused
postponements and delays in executing contracts.  There was also a decline in
bidding opportunities for the testing service area as a number of customers
had budget constraints and the state and federal government still at odds in
the pollution control area led to the delay of awarding and state-up of
government contracts for the analytical laboratory.

      Field testing service revenues were $2,356,553 compared to $2,778,032
for fiscal 1995 for a 15% decrease.  This decrease was due in part to the
decrease in services for a pollution control monitoring system supplier for
stack testing particularly related to continuous emission monitors for
electric utilities which was a major part of the fiscal 1995 field testing
services.  Although the number of contracts serviced in fiscal 1996 were
about the same as the previous year, the dollar amounts of the contracts were
somewhat lower.  Major customers for fiscal 1996 included two electric power
utility plants, an air pollution control product manufacturer and two
municipal waste incinerator plants representing 31% of field testing
services.

      Revenues for analytical laboratory services were $2,904,652 for the
year compared to $2,769,169 for fiscal 1995 for an increase of 5%. 
Commercial revenues were up 10% and included increases in groundwater
monitoring and CERCLA soil remedition activities.  Government revenues were
down 56% for the current year due to the U.S. congressional budget impasse.
This not only caused delays in the incremental funding of existing contracts
but produced delays in awarding several new contracts for which the
laboratory had negotiated a best and final status.  Because of the severe
winter weather the commercial and government projects scheduled during the
third quarter were delayed and re-scheduled up to three months later.
<PAGE>

      Regulatory assistance revenues were $534,889 compared to $490,531 for
an increase of 9% over the fiscal 1995 revenues.  Major customers comprising
59% of the total included a paper manufacturer, a chemical manufacturer, an
iron foundry and a railroad company.  Revenues for monitoring services were
$160,914 for fiscal 1996 compared to $84,475 for fiscal 1995 for an increase
of 91%.  Two customers, a printing company and a chemical plant, accounted
for 93% of the total monitoring service revenues.

      Revenues for consulting/engineering services for fiscal 1996 were
$354,484 compared to $492,490 for fiscal 1995 for a 28% decrease.  Consulting
services revenues were $112,033 which was an increase of 58% over the prior
years' revenues of $70,761 with major customers being a government contractor
consultant and research firm for 54% and an electric utility plant for 27% of 
the total consulting revenues.  The increase was due largely to the increased
services for the same government contractor over fiscal 1995.  Revenues for
engineering were $116,278 for fiscal 1996 compared to $349,395 for fiscal
1995 for a 67% decrease.  Major customers for the current year consisted of
two steel manufacturers for 89% of the total engineering.  The decrease in
revenues was due to a decrease in services from fiscal 1995 for one of these
steel manufacturers.

      Revenues for in-house projects which consist of sale of books were
$38,213 compared to $17,916 for fiscal 1995 for an increase of 113%. 
Additional tutorials have been added to the line of books.  To educate the
public on the availability of our books, promotional material is being
included with the seminar materials and some promotional mailings are been
made. Seminar revenues were $87,960 compared to $54,418 a year ago for a 62%
increase.  The current year included revenues from a seminar sponsored by the
United States Agency for International Development (USAID) for an Air
Pollution Control Technologies course which commenced in the third quarter
and provided 76% of fiscal 1996 seminar revenues and the increase for the
year.

      Product revenues were $8,430 for fiscal 1996 compared to $17,737 for a
decrease of 52% and included both the Baghouse Performance Monitoring (BPM)
hardware and software products.  Anew clear air regulation includes a section
that will require baghouse operators to provide more exact monitoring with a
record of the problems and the corrective actions taken.  ETS has proposed to
the Environmental Protection Agency (EPA) that the BPM be considered as an
acceptable protocol for logging and monitoring this information.

      Construction revenues for fiscal 1996 were $14,219,339 compared to
$13,279,472 for fiscal 1995 for a 7% increase.  The current year experienced
growth in some areas of business while some areas showed a decline in the
sales.  Construction activities in general were slow due to higher interest
rate and a severe winter.  Irrigation showed a significant growth and this
growth pattern is expected to continue in fiscal 1997.  However, the utility
and septic construction experienced a decline in overall activities in terms
of sales and bidding.  Fortunately, toward the end of year, both of these
areas showed improvements in bidding inquiries which will result in sales
growth for the future. Even with the increase in sales for fiscal 1996, the
construction business had a large loss for the year. The nature and cost of
projects during the fiscal 1996 were heavily weighted toward materials rather
than labor and equipment components.  The local area economy was slow and
market competitive pressures kept prices of projects at lower levels thereby
further reducing gross profit margins.  Adverse weather conditions brought
construction to a standstill during the third quarter and the first part of
fourth quarter, thereby delaying work until late fourth quarter of fiscal
1996.
<PAGE>
      Cost of goods and services for fiscal 1996 were $18,555,761 or 90% of
revenues compared to $16,376,725 or 82% of revenues during fiscal 1995.  This
increase was attributed to price erosions due to competitive pricing
resulting in higher cost in executing the work, the delays experienced with
the unfavorable weather conditions and the nature and cost of projects
heavily weighted toward materials rather than labor and equipment.

      With a 3% increase in revenues and an increase of 13% in the cost of
goods and services, the gross profit for the year ended at $1,983,500 or 10%
of revenues for the current year compared to a gross profit of $3,535,181 or
18% of revenues for fiscal 1995.

      Selling, general and administrative expenses for the current year were
$3,622,064 or 18% of revenues compared to $3,038,565 or 15% of revenues for
fiscal 1995. The increase is the result of additional legal expense and added
facilities relating to acquisitions and an overall general increase in office
operations.

      Interest income from savings on deposit for fiscal 1996 was $21,107
compared to $26,610 for fiscal 1995.  Interest expense representing the
interest for utilization of the credit line and interest paid in financing of
capital equipment was $392,131 for the current year compared to $348,870 for
fiscal 1995.  Other income representing the sale of miscellaneous scrap
materials was $10,797 compared to $22,266 for fiscal 1995.

      Net loss for fiscal 1996 was $1,998,791 compared to net income of
$502,666 for fiscal 1995.  The current year loss was a result of several
factors.  All the subsidiaries were affected by the unfavorable weather
conditions causing delay, a decline in bidding opportunities due to budget
constraints of customers, competition pressure keeping margins low, and the
state and federal government still at odds delaying awarding of contracts.

      Liquidity And Capital Resources As Of The end of Fiscal Year 1997 

      During fiscal 1997, the Company issued $160,881 of common stock and
options for services ($131,440 in prepaid expenses at May 31, 1997).  As of
May 31, 1997, there were 3,382,900 stock options outstanding to employees,
directors and consultants with expiration dates of November 4, 1997 through
February 4, 2002 and 1,545,875 outstanding warrants to various persons with
expiration dates of December 28, 1999 through February 27, 2002.

      In the second quarter of fiscal 1997, the Company sold shares of its
common stock, no par value, to Thomas W. Marmon, a member of the Company's
Board of Directors, in connection with the conversion by Mr. Marmon of
$500,000 of ETS debt securities.  The sale was made pursuant to a private
placement under Section 4(2) of the Securities Act of 1933, and the shares
acquired are deemed "restricted securities" subject to the holding period and
other requirements of Rule 144 under the Securities Act.
 
      In the third quarter, the Company's bank line of credit was replaced
with a secured note of up to $2,500,000.  The initial advance under the note
was $2,000,000.  The note which establishes the facility calls for a fixed
monthly interest of $25,000 over a two year term, subject to call by the
holder upon 60 days notice and is secured by the assets of the Company and it
subsidiaries.  The $2,000,000 was used to payoff the bank credit line, a note
with a bank and a note due Mr. Thomas W. Marmon, a member of the Company's
Board of Directors.  The $25,000 fixed interest is equivalent to a 15% annual
interest rate.  The Company may repay the note at any time without penalty
<PAGE>
upon 60 days notice and the lender may call the note at any time upon 60 days
notice.  The Company may borrow an additional $500,000 at the lender's
discretion upon review of the Company's financial condition and the value of
the collateral.  The credit facility is provided by a trust for the benefit
of an ETSI investor and director, Thomas W. Marmon. 

      Pursuant to a Regulation S Convertible Debentures Purchase Agreement
dated as of February 28, 1997, and a Regulation S Warrants Purchase Agreement
dated as of February 28, 1997, the Company placed $750,000 of its 7%
Convertible Debentures due February 27, 2002 and issued warrants to purchase
1,000,000 shares of the Company's common stock, no par value.  The debentures
are convertible into the Company's common stock at the lower of $.76 or 65
percent of the average closing bid price of the common stock for the five
trading days immediately preceding the conversion date. The offering was made
under the Securities registration set forth in Regulation S under the 1933
Act to a foreign institutional investor and/or agents associated with the
transaction.  The holder of the Debentures is entitled to convert the
Debentures initially issued to such holder beginning forty-five days after
the closing date into that number of fully paid and nonassessable shares of
the Company's common stock.

      Major components of cash flow used in operating activities included an
increase in accounts receivable of $1,235,534, an increase in costs and
estimated earnings in excess of billings on uncompleted contracts of $447,606
and an increase in amortization of deferred gain on sale/leaseback of
$304,308 which was offset by depreciation and amortization and increase in
accounts payable resulting in  net cash used in operating activities of
$1,064,865. Net cash used in investing activities of $995,928 included
purchases of property, plant and equipment of $820,374. Net cash provided by
financing activities included the following major components:  notes payable
to stockholder of $1,900,000, proceeds from convertible debentures of
$750,000,  proceeds from long-term debt of $507,382 and proceeds from
issuance of common stock of $304,993 which was  offset by decrease in notes
payable to banks and payments on long-term debt resulting in net cash
provided of $2,033,814.  Net cash and cash equivalents at May 31, 1997 was
$94,734 compared to $121,713 at May 31, 1996.

      The Company had net income of $148,435 from operations in 1997, a
substantial improvement from a loss of $1,998,791 in 1996.  The Company
currently anticipates continued profitable operations in 1998.  At May 31,
1997, the Company had current assets of $7,814,274 and current liabilities of
$6,955,871.  Subsequent to May 31, 1997, the Company obtained $500,000 of
loans with a one-year maturity for working capital purposes and a commitment
for financing with a one-year maturity for $426,250.  The Company has
earmarked these funds to pay off the debt of $426,250 to repurchase 269,565
shares of common stock under a repurchase agreement.  The Company has
received a proposal from an asset based lender outlining parameters for
proposed financing of up to $5,000,000 to enable the Company to pay off
certain existing debt and to provide future working capital.  The proposal is
not a commitment to fund and any funding is subject to final negotiations,
execution and delivery of legal documentation in form and substance
satisfactory to the lender and its legal counsel, completion of the lender's
due diligence, meeting required terms outlined in the proposal, and
documentation including provisions customary to asset based lending.  The
Company has a letter of understanding based upon the Company's receipt of a
future contract that $600,000 of funds will be provided through an offering
of Regulation S 7% preferred stock and the Company will grant warrants to
<PAGE>
purchase 750,000 shares of its common stock, no par value, for $.80 per share
for a period of three years.  In addition, as part of the letter of
understanding the 1,000,000 of warrants for common stock issued with the 7%
convertible debentures will have a strike price of $.50.  As stated above the
proposal for additional debt financing of up to $5,000,000 is subject to a
number of future conditions the Company will need to comply with to
successfully complete the financing.  The letter of understanding relating to
the $600,000 of equity financing is subject to the Company receiving the
China Steel LEC contract.  There can be no assurance that such conditions
will be satisfied or that such financing will be obtained.  

      Stockholders' equity has increased to $3,162,635 in 1997 from
$1,488,306 in 1996.  This increase has resulted from net income of $148,435,
proceeds from sale of stock of $304,989, issuance of common stock for
services of $160,881, conversion of debt to stock of $550,776, issuance of
warrants of $173,334 and discount on issuance of convertible debentures of
$410,914.  Repurchase of common stock amounted to $75,000.

      Backlog at May 31, 1997 was $7,983,921 compared to $6,844,851 at May
31, 1996. ETS  and ETSAS held open orders from various clients, including
commercial clients as well as federal and state government agencies. If all
the work under these open orders is authorized, the Company estimates that
its backlog would increase by $662,966 to a total of $8,646,887 compared to
open orders at May 31, 1996 of $1,181,866 to a total backlog of $8,026,717. 
This increase in total backlog reflects increase in the construction and
rehabilitation areas of the construction company.    

      Most of ETSI's contracts are of short-term duration and are completed
within a few months of the order or award.  Certain contracts such as those
from utilities  are annual and are completed in stages against task orders. 
Government agencies often issue open orders for which subsequent task orders
are issued.  There are no conditions precedent to the issuance of task orders
and they are issued pursuant to the specific orders of the client for the
services.  Experience shows that substantially all open orders ultimately
result in task orders and at times have exceeded the amount of the open
order.  There can be no assurance that existing contracts or future contracts
containing open orders will result in task orders covering the entire
contractual amounts.  ETSI is not aware of any significant unrecognized cost
to complete any open contract.

      New orders received for fiscal 1997 amount to $24,919,489.  Since the
close of the fiscal year, ETS was selected by China Steel in Taiwan to supply
three of the Company's LEC systems for a value of approximately $7,000,000. 
In fiscal 1997, ETSI consummated a license agreement with E & C Engineering,
a subsidiary of one of Taiwan's largest and most prominent engineering firms. 
They provide full range engineering and construction services to utility and
industrial power users throughout Asia. This agreement enables E & C to
exclusively market and supply the LEC to those end-users in Taiwan.  ETSW,
since the close of the fiscal year, received two major contracts for
installing water mains.  One from the Virginia Department of Transportation
totaling $1,168,492 and one from the City of Petersburg in the amount of
$635,000.   

      Preliminary proposals for the LEC have also been submitted in Poland,
Czech Republic and India.  LEC licensing activities continue in Korea and
separate confidentiality agreements have been signed with Jindo and Hyundai
Heavy Industries.  A letter of intent from Hyundai is expected in September,
1997 and a memorandum of understanding with Jindo for ETSI air pollution
<PAGE>
control services is anticipated during fiscal 1998.  Marketing efforts for
ETSI air pollution control products and services continue in the Pacific Rim,
Asia, Eastern Europe and Mexico.  Similar activities are scheduled for Brazil
and other select South American countries in fiscal 1998.

Independent Auditors' Report 



The Board of Directors and Stockholders
ETS International, Inc. and subsidiaries:


We have audited the accompanying consolidated balance sheets of ETS
International, Inc. and subsidiaries as of May 31, 1997 and 1996, and the
related consolidated statements of income (loss), stockholders' equity and
cash flows for each of the years in the three-year period ended May 31, 1997. 
These consolidated financial statements are the responsibility of the
Company's management.  Our responsibility is to express an opinion on these
consolidated 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of ETS
International, Inc. and subsidiaries as of May 31, 1997 and 1996, and the
results of their operations and their cash flows for each of the years in the
three-year period ended May 31, 1997, in conformity with generally accepted
accounting principles.

Notes to Consolidated Financial Statements

May 31, 1997, 1996 and 1995

=============================================================================

(1)   Significant Accounting Policies

      Currency

      All references to dollars ($) are United States dollars unless
      otherwise denoted as Canadian (CDN).

      Principles of Consolidation

      The consolidated financial statements include the accounts of ETS
      International, Inc. and its wholly-owned subsidiaries, ETS, Inc., ETS
      Analytical Services, Inc. and ETS Water and Waste Management, Inc.
      ("the Company").  Significant intercompany accounts and transactions
      have been eliminated in consolidation.

      Cash Equivalents

      The Company considers all highly liquid investments with a maturity of
      three months or less when purchased to be cash equivalents.

      Inventories

      Inventories, consisting of raw materials ($351,856 in 1997 and $330,754
      in 1996) and supplies ($419,932 in 1997 and $219,975 in 1996), are
      stated at the lower of cost (first-in, first-out method) or market.

      Long-term Contracts

      Revenues on uncompleted long-term contracts are recorded using the
      percentage-of-completion method.  Provisions are made for estimated
      losses at the time the losses are determinable.  Revenues related to
      certain government contracts are subject to adjustments upon audit of
      costs by the government, with any such adjustments reflected in the
      accounting period in which determined.  For the year ended May 31,
      1997, the Company recognized approximately $225,000 in income from
      adjustments to prior year contracts.  Billings are prepared according
      to specific terms of individual contracts.  Contracts will generally
      provide for periodic payments as work is completed with final amounts
      due upon completion and acceptance of the project by the customer.

      Property, Plant and Equipment

      Property, plant and equipment are stated on the basis of cost. 
      Property and equipment under capital leases are stated at the present
      value of minimum lease payments at the inception of the lease.


                                                                (Continued)

      straight-line basis over the shorter of the lease term or the estimated
      useful life of the asset.  Leasehold improvements are amortized on the
      straight-line basis over the shorter of the lease term or the estimated
      useful life of the improvement.

      Patents

      The Company has incurred costs related to patent applications which
      have been or will be made.  Costs related to patents granted are being
      amortized over a period of 17 years using the straight-line method. 
      Costs relating to patents pending are deferred until the patent is
      granted.

      Prepublication Costs

      Prepublication costs related to the Company's production of textbooks
      and other training materials are stated at the lower of cost or market. 
      These deferred costs are amortized over a period of 5 years from
      publication date using the straight-line method.

      Goodwill

      Goodwill, which represents the excess of purchase price over fair value
      of net assets acquired, is amortized on a straight-line basis over
      periods not exceeding 15 years.  The Company assesses the
      recoverability of this intangible asset by determining whether the
      amortization of the goodwill balance over its remaining life can be
      recovered through undiscounted future operating cash flows of the
      acquired operations.  The amount of goodwill impairment, if any, is
      measured based on projected discounted future operating cash flows
      using a discount rate reflecting the Company's average cost of funds.

      Research and Development

      Research and development costs are charged to operations as incurred.

      Income Taxes

      Income taxes are accounted for under the asset and liability method. 
      Deferred tax assets and liabilities are recognized for the future tax
      consequences attributable to differences between the financial
      statement carrying amounts of existing assets and liabilities and their
      respective tax bases.  Deferred tax assets and liabilities are measured
      using enacted tax rates expected to apply to taxable income in the
      years in which those temporary differences are expected to be

      recovered or settled.  The effect on deferred tax assets and
      liabilities of a change in tax rates is recognized in income in the
      period that includes the enactment date.

      Earnings Per Share

      Earnings per share have been computed on the basis of weighted average
      number of shares outstanding.  Stock options and warrants have been
      excluded for the years ended May 31, 1997, 1996 and 1995, due to their
      antidilutive effect on earnings per share.

      Licensing Agreements

      The Company has licensing agreements with certain customers to sell
      proprietary products developed by the Company, including the Limestone
      Emission Control (LEC) System and the Dry Reactor.  The Company is to
      receive amounts ranging from five percent to eight percent of gross
      sales as royalties for the sale of these proprietary products.  Minimum
      royalty fees are recognized when due from the licensee based on product
      sales, training completion and terms of the license agreements.  These
      agreements contain certain restrictive clauses requiring the licensees
      to meet minimum sales targets or the license agreement may be revoked
      at the Company's option.  The LEC system incorporates some claims of a
      patent issued to the U.S. Department of Energy (DOE).  Under terms of
      an agreement with the DOE, the Company is required to pay the DOE a
      royalty fee of one percent.  No royalty fees or expenses were
      recognized by the Company for the years ended May 31, 1997, 1996 and
      1995.

      Stock Options and Warrants

      Prior to June 1, 1996, the Company accounted for its stock options and
      warrants in accordance with the provisions of Accounting Principles
      Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees,
      and related interpretations.  As such, compensation expense was
      recorded on the date of grant only if the current market price of the
      underlying stock exceeded the exercise price.  On June 1, 1996, the
      Company adopted Statement of Financial Accounting Standards No. 123,
      Accounting for Stock-Based Compensation (Statement 123), which permits
      entities to recognize as expense over the vesting period the fair value
      of all stock-based awards on the date of grant.  Alternatively,
      Statement 123 also allows entities to continue to apply the provisions
      of APB Opinion No. 25 and provide pro forma net income or loss and pro
      forma net income or loss per common share disclosures for stock option
      and warrant grants made in 1996 and future years as if the
      fair-value-based method defined in Statement 123 had been applied.  The
      Company has elected to continue to apply the provisions of APB Opinion
      No. 25 and provide the pro forma disclosure provisions of Statement
      123.

      Use of Estimates

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

      Reclassifications
 
      Certain reclassifications have been made to the 1996 financial
      statements to conform to classifications used in 1997.

(2)   Business Combinations

      On June 1, 1994, ETS International, Inc. acquired the common stock of
      Stamie E. Lyttle, Inc., Lyttle Utilities, Inc. and LPS, Inc. (the
      "Lyttle Companies") in exchange for 2,730,000 shares of ETS
      International, Inc.'s common stock.  On January 19, 1995, ETS
      International, Inc. acquired the common stock of Environmental
      Laboratories Incorporated (ELI) in exchange for 183,600 shares of ETS
      International, Inc.'s common stock.  These acquisitions were accounted
      for by the pooling-of-interests method and, accordingly, the
      consolidated financial statements include the operations of the Lyttle
      Companies and ELI for all periods presented.  There were no material
      adjustments of the net assets of the Lyttle Companies or ELI as a
      result of adopting the same accounting practices as ETS International,
      Inc. and its subsidiaries.

      On April 3, 1995, ETS International, Inc. acquired the net assets of
      Air Compliance, Inc. in exchange for 113,000 shares of ETS
      International, Inc.'s common stock.  On February 5, 1996, ETS
      International, Inc. acquired certain assets of Olympic Industries, Inc.
      in exchange for 539,130 shares of ETS International, Inc.'s common
      stock (see note 8).  On April 18, 1996, ETS International, Inc.
      acquired certain laboratory assets of Dewberry and Davis, Inc. in
      exchange for 65,617 shares of ETS International, Inc. common stock. 
      These acquisitions were accounted for as purchases; accordingly, the
      results of operations of the acquired entities are included in the
      consolidated financial statements only from the date of acquisition. 
      Proforma results of operations are not presented because the effect is
      not material to the consolidated financial statements.  The goodwill
      arising as a result of the excess of the purchase price over the fair
      value of net assets acquired is being amortized on a straight-line
      basis over periods not exceeding 15 years.

      On February 28, 1997, the Company issued $750,000 of 7 percent
      convertible debentures due February 27, 2002.  The holder of the
      debentures is entitled to convert them into common stock at his option. 
      The Company may at its option force conversion after one year from
      February 28, 1997.  The Company is not required to pay cash to retire
      the debentures and the accrued interest.  The debentures are
      convertible into the Company's common stock at the lower of $.76 or 65
      percent of the average closing bid price of the common stock for the
      five trading days immediately preceding the conversion date.  Since the
      conversion rate was lower than the market price of the common stock on
      the date of issuance, a discount of $403,846 was recognized on the
      debentures.  In addition, 1,000,000 warrants for common stock were
      issued with the convertible debentures.  The fair value of these
      warrants, $173,334, was recorded as part of the discount.  The total
      discount of $577,180 is being amortized as interest expense over a year
      using the interest rate method.

      On May 20, 1997, the Company issued 145,335 shares of common stock upon
      the conversion of $50,776 of the convertible debentures, which includes
      $776 of accrued interest.

      In assessing the realizability of deferred tax assets, management
      considers whether it is more likely than not that some portion or all
      of the deferred tax assets will not be realized.  The ultimate
      realization of deferred tax assets is dependent upon the generation of
      future taxable income during the periods in which those temporary
      differences become deductible.  Management considers the scheduled
      reversal of deferred tax liabilities, projected future taxable income
      and tax planning strategies in making this assessment.  Based upon the
      level of historical taxable losses and projections for future taxable
      income over the periods which the deferred tax assets are deductible,
      management believes it is more likely than not the Company will not
      realize the benefits of these deductible differences and loss
      carryforwards in excess of the amount which can be offset by the
      reversal of future taxable items.

(8)   Common Stock Subject to Repurchase Agreement

      In connection with the Olympic Industries, Inc. asset acquisition (see
      note 2), the Company entered into a common stock repurchase agreement
      (the "repurchase agreement").  Under the repurchase agreement, the
      Company is obligated to repurchase at the stock price set forth in the
      Asset Purchase Agreement ($1.43 per share) up to one-half of the issued
      shares on the first anniversary of the acquisition and up to one-half
      of the issued shares on the second anniversary of the acquisition. 
      Accordingly, the 539,130 shares issued in connection with the asset
      acquisition have been classified as common stock subject to repurchase
      at their aggregate repurchase price of $775,000.  As security for the
      Company's obligation to repurchase the shares, the Company granted the
      seller a security interest in the assets purchased.  The Company may
      satisfy its obligation related to the shares (269,565 shares) subject
      to repurchase on the second anniversary in February 1998 upon the
      successful registration of the issued shares with the Securities and
      Exchange Commission (SEC).  It is the Company's intention to complete
      this registration; however, upon completion, it will be subject to
      final SEC approval.  If the stock is not registered and the Company is
      requested to repurchase the stock on the second anniversary, the
      Company can pay a fee of $38,750 and extend the repurchase date until
      September 1998. 

      In February 1997, Olympic Industries, Inc. elected to have the Company
      repurchase one-half of the issued shares (269,565 shares) at the first
      anniversary of the acquisition.  Accordingly, this obligation of
      $409,642 including interest of $22,142 is shown as current.  The
      Company elected to defer the repurchase until September 1997.

      The per share weighted-average fair values of stock options and
      warrants granted during 1997 and 1996 were $.29 and $.18 on the various
      dates of grant using the Black-Scholes option-pricing model with the
      following weighted-average assumptions:  1997 - expected dividend yield
      of 0 percent, risk-free interest rate of 6.29 percent, expected
      volatility of 20 percent and an expected life of 2 to 4 years; 1996 -
      expected dividend yield of 0 percent, risk-free interest rate of 6.36
      percent, expected volatility of 20 percent and an expected life of 4
      years.

      The Company uses the intrinsic value method of APB Opinion No. 25 for
      recognizing stock-based compensation in the financial statements.  Had
      the Company determined compensation cost based on the fair value at the
      grant date for its stock options and warrants under the provisions of
      Statement 123, the Company's net income (loss) and net income (loss)

      Pro forma net income (loss) reflects only options granted in 1997 and
      1996.  Therefore, the full impact of calculating compensation cost for
      stock options under Statement 123 is not reflected in the pro forma net
      income (loss) amounts presented above because compensation cost is
      reflected over the options' vesting periods and compensation cost for
      options granted prior to June 1, 1995 is not considered.


(10)  Related Party Transactions

      The Company and its subsidiaries lease various office space and
      laboratories from entities whose members include certain officers and
      directors of the Company.  Rent expense under these operating leases
      approximated $417,000, $405,000 and $399,000 for 1997, 1996 and 1995,
      respectively.

      Other accounts receivable consists primarily of advances to officers,
      directors and other employees.  At May 31, 1997 and 1996, $91,381 and
      $76,265, respectively, were the result of these advances.

      The Company has notes receivable from officers of $408,846 and $391,799
      as of May 31, 1997 and 1996, respectively.  The notes bear interest at
      six percent.  As of May 31, 1997, $64,694 is due on demand and $344,152
      is due in July 1998.

      The Company has notes payable to affiliates of $490,617 and $348,625 as
      of May 31, 1997 and 1996, respectively.  These affiliates include
      certain partnerships and individuals whose members are officers and
      directors of the Company.  The balance at May 31, 1997 includes
      $289,159 classified as current.  The remaining balance of $201,458 is
      due in fiscal 1999.  The notes bear interest at rates between six and
      twenty percent.

      In March 1997, the Company borrowed $2,000,000 from a stockholder.  The
      note is due March 17, 1999, however, the stockholder has the option to
      accelerate the entire principal and interest owed and demand payment in
      full upon sixty days notice.  Due to this acceleration clause, the
      entire amount is shown as current.  The note bears interest at fifteen
      percent which is payable monthly.  The Company may borrow an additional
      $500,000 from the stockholder at his discretion upon review of the
      Company's financial condition and the value of the collateral.  The
      note is collateralized by accounts receivable, inventories and property
      and equipment.  At May 31, 1996, the Company had a note payable to
      stockholder of $600,000, which was paid in full during 1997.

      During 1995, the Company received $304,044 of life insurance proceeds
      as a result of the death of one of its officers.  Subsequent to the
      officer's death, the Company repurchased 216,809 shares from the estate
      of the officer.  The shares repurchased included 100,000 shares
      exercisable under available options.  The shares were repurchased at
      their approximate fair market value at the date of the officer's death.

(11)  Other Matters

      The Company does not receive hazardous waste during the normal course
      of business.  The Company does receive environmental samples for
      analysis; and, occasionally, in the process of analysis, small
      quantities of hazardous waste are generated.  Such waste is stored in

      areas, lab packed for disposal, picked up by licensed hazardous waste
      contractors and transported to licensed disposal facilities.  In
      addition to its laboratory activities, the Company is engaged in field
      testing.  It is the Company's intention to conduct its operations in an
      effective, safe and prudent manner, and to ensure against potential
      risks.  The Company carries workers' compensation insurance for its
      employees and insurance for any personal liability and injury which
      could occur to nonemployees and/or the property of others.

      The Company is involved from time to time in litigation and
      environmental matters; however, it is the opinion of management that
      there are no matters currently existing which would have a material
      impact on the financial position or results of operations of the
      Company.


(12)  Fair Value of Financial Instruments

      Statement of Financial Accounting Standards No. 107, Disclosures about
      Fair Value of Financial Instruments (SFAS 107), requires the Company to
      disclose estimated fair values of its financial instruments.  SFAS 107
      defines the fair value of a financial instrument as the amount at which
      the instrument could be exchanged in a current transaction between
      willing parties.

      The following methods and assumptions were used to estimate the fair
      value of each class of financial instruments:  The carrying amounts
      reported in the consolidated balance sheets for cash and cash
      equivalents, notes receivable, notes payable and long-term debt
      approximate fair value.  The fair value of notes receivable is
      estimated by discounting the future cash flows at rates the Company
      would currently receive for similar notes receivable.  The fair values
      of notes payable and long-term debt is estimated by discounting the
      future cash flows of each instrument at rates currently offered to the
      Company for similar debt instruments of comparable maturities by the
      Company's bank.


(13)  Fourth Quarter Adjustments

      Significant adjustments to the fourth quarter for the year ended May
      31, 1997 included a charge of approximately $75,000 as a provision for
      bad debts based on specific reviews of customer accounts and a $95,000
      charge to correctly state costs and earnings in excess of billings.

(14)  New Accounting Standard

      In February 1997, the Financial Accounting Standards Board issued
      Statement of Financial Accounting Standards No. 128, Earnings per Share
      (SFAS 128).  SFAS 128 establishes standards for computing and
      presenting earnings per share.  The Company is required to adopt this
      statement in fiscal 1998.  The adoption of this statement by the
      Company is not anticipated to have a material effect on earnings per
      share presented in the current or prior years.

reasonable in relation to the general executive, managerial and professional

other prospective future employers of the Executive, and (ii) the scope of
the noncompetition provisions hereunder is reasonable, legitimate and fair to
the Executive.  Accordingly, Executive agrees that during his employment with

behalf of any other person or entity) any business relationship similar to

                   --------

of any such event, and after receiving written notice from the Contractor
thereof, Licensor shall, for as long as such event shall continue to prevent
such achievement, reduce any Performance Objective so affected by a
proportion that reasonably accounts for such event.  The Contractor shall
promptly deliver written notice to the Licensor that such event shall have

any such inspections in its practices of the methods of the Subject Matter
made by the Licensor.  At all times the Contractor shall exert diligent

                  (vi)   fails to submit and deliver to the Licensor any
written report required under paragraph (a) of Section 3.05 hereof when due
and such failure shall continue for a period of 30 days after written notice
from the Licensor to the Contractor.
            (b)   In the event the Contractor fails to pay the License Fee or
any Cross-Over Payment in accordance with Article III hereof, or fails to
provide any written report required under paragraph (b) of Section 3.05
hereof in accordance with such provision and, in the case of the first such
breach in any calendar year, such failure shall continue for a period of 30
days after written notice from the Licensor to the Contractor, then in any
such event, this Agreement shall automatically terminate.
            (c)   No termination under this Section 6.02 shall limit or
affect any other right or remedy of the Licensor, including the right to
damages resulting from the Contractor's breach.
      6.03  Consequences of Expiration or Termination.
            (a)   Upon expiration or termination of this Agreement, the
Contractor shall promptly pay the Licensor all amounts then due under this
Agreement, terminate all use by it of any service mark, tradename, trademark
certification mark or corporate name that includes any of the foregoing
words: avoid all subsequent use of all service marks, tradenames, trademarks,
certification marks or corporate names likely to be confused with ULTRALINER
as well as all stationery, invoices, signs or other visual devices displaying
or otherwise associated with ULTRALINER; terminate all use of the Subject
Matter and the Licensor's Confidential Material, as well as the use and sale
of any products under any Patent Rights or Copyrights or the Know-how; and
assign to the Licensor free of charge, any and all rights and claims to any
and all rights arising from the use of ULTRALINER, or any combination
involving ULTRALINER, the above mentioned Corporate rights in the Territory;
and return to the Licensor all Confidential Material in its possession, and
any copies which it has made of the same.  Following termination, the
Contractor shall continue to be obligated to provide all after sales services
for which it has theretofore contracted, including the honoring of all
contract warranties.  Should the Contractor fail to fulfill such obligations,
and should the Licensor, in its reasonable discretion after notice to the
Contractor, whether for reason of preserving product goodwill or otherwise,
choose to perform any such obligations (this paragraph in no way to be
construed as an assumption by the Licensor of any obligations for which it is
not specifically contractually responsible), then the Contractor shall
promptly reimburse the Licensor the reasonable charges issued by the Licensor
to the Contractor of performing such obligations of the Contractor.  If the
Contractor is a corporation having the word ULTRALINER as a part of its
corporate name, the Contractor shall, within 60 days of termination, amend
its corporate name to remove the word ULTRALINER therefrom.
            (b)   Each party hereto shall promptly pay to the other party all
damages, costs and expenses, including reasonable attorney's fees, incurred
by such other party by reason of default on the part of such party hereto,
whether or not such default occurred prior to or subsequent to the
termination or expiration of this Agreement, and said sum shall include all
<PAGE>
costs and expenses, including reasonable attorney's fees, incurred by such
other non-defaulting party in obtaining injunctive or other relief to enforce
the provisions of this Agreement.  Notwithstanding the foregoing, in any
dispute under this agreement, the ultimate prevailing party shall be entitled
to recover from the other party its reasonable attorney's fees.  No right or
remedy herein conferred upon or reserved to either party is exclusive of any
other right or remedy herein or by law or equity provided or permitted; but
each shall be cumulative of every right or remedy given hereunder.  In
addition to whatever remedy or remedies a party may have by way of damages
for violation of the provisions of this Agreement and/or expiration or
termination of the same, such party shall also have the right to injunctive
relief to enforce the provisions of this Agreement.
            (c)   In the event of the termination of this Agreement by the
Licensor or Contractor as a consequence of any event described under sub-
paragraphs (i), (iii), or (vi) of Paragraph (a) of Section 6.02 or 6.01
hereof, the Licensor shall thereafter assist the Contractor in disposing of
any Materials or Apparatus then in the possession of the Contractor,
including but not limited to the sale of excess inventory to other qualified
Licensees, subject in such case to the constraints of the Licensor's business
and its other obligations.  
            (d)   Licensor shall supply to the Contractor, at the current
rates and prices, any and all materials or apparatus Contractor may need to
complete any outstanding projects or projects that may have been bid prior to
the termination, but not awarded, and a bid bond was provided by the
Contractor, provided the Contractor is not in default of any provision of
Section 6.02.

ARTICLE VII - WARRANTIES; INDEMNIFICATION

      7.01  Limited Subject Matter Warranty.
            (a)   The Licensor represents and warrants that the Product can
successfully rehabilitate many types of sewer (sewerage and storm) and water
pipelines within the Permitted Uses when installation is properly performed. 
Every reasonable precaution will be taken by the Licensor in compiling all
data, and offering instructions in the methods of use of the Product
purchased from the Licensor for operation hereunder, to assure compliance
with the Licensor's exacting standards and that the use of the Subject Matter
for the Permitted Uses in accordance with the terms and conditions of this
Agreement maintains a high standard of quality.  To the best of the
Licensor's knowledge, all information given will be correct in all material
respects.  However, it is impossible to anticipate every possible variation
in the manner of use or the conditions under which the Contractor will apply
the Product and Licensor makes no warranty or representation of results which
the Contractor will attain, and, except as stated above, shall under no
circumstances be held responsible for any such results that occur as a
consequence of a departure from the instructions provided by the Licensor or
from negligence or malfeasance on the part of the Contractor.
            (b)   Licensor does warrant that the Product will comply with
Licensor's standard specifications and will perform in the Permitted Uses as
described herein and for a period of one year, or as may be required by
customers for a particular project, from the date of sale will not fail in
the performance in such uses on account of manufacturing defects.  In the
event of any such failure, the liability of the Licensor shall be limited to
the replacement of the product that has failed.
      THE FOREGOING WARRANTY IS IN LIEU OF AND EXCLUDES ALL OTHER WARRANTIES
NOT EXPRESSLY SET FORTH HEREIN, WHETHER EXPRESSED OR IMPLIED BY OPERATION OF
LAW OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY OF
FITNESS FOR ANY PURPOSE OTHER THAN AS IS CONTEMPLATED BY THIS AGREEMENT.  
<PAGE>
      LICENSOR SHALL NOT BE LIABLE FOR EXEMPLARY, PUNITIVE, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF
PROFITS OR REVENUES, LOSS OF USE OF GOODS OR EQUIPMENT, DAMAGE TO PROPERTY,
COST OF CAPITAL, COST OF SUBSTITUTION OF GOODS OR COVER, LIQUIDATED DAMAGES,
CLAIMS BY PURCHASERS FROM CONTRACTOR  LICENSOR'S LIABILITY TO CONTRACTOR IS
LIMITED TO REPLACEMENT OF GOODS NOT COMPLYING WITH THE AGREEMENT, OR, AT
LICENSOR'S ELECTION, TO THE REFUNDING OR CREDITING OF THE PRICE PAID FOR THE
GOODS, WHETHER THE CLAIM ASSERTED IS IN CONTRACT OR TORT.
      The Licensor makes no representation nor warranty that ULTRALINER PVC
ALLOY (Trade Mark) or ULTRALINER PVC ALLOY PIPELINER (Trade Mark) or
ULTRALINER PVC ALLOY PIPELINER SYSTEM (Trade Mark) is available for use as a
service mark, tradename, trademark, and/or certificate mark in the United
States.
      Further, except as expressly set forth in this Article VII, the
Licensor shall not be held responsible for use by the Contractor of any
Product, Materials, Apparatus, Know-how, Patents Rights or Confidential
Material in such manner as to infringe any patent, trademark or copyright
owned by another.  The Licensor warrants that it has rights to the patents
pertaining to the Materials subject to no lien, encumbrance or charge
whatsoever.
      7.02  Forbearance by Contractor.
      The Contractor expressly covenants that during the Term and after the
expiration or termination thereof, the Contractor shall not, directly or in-
directly, contest or aid in contesting the validity, or the ownership or
licensing by the Licensor, of the Subject Matter, the Know-how, any Patent
Rights and any Copyrights, as well as any trademarks, service marks, trade
names, and copyrights described under Section 2.02, or the limitation of the
Contractor's right with respect to the Subject Matter by the terms and
provisions of this Agreement.  The Contractor agrees promptly to notify the
Licensor of any claim, demand, suit or litigation based upon or arising from,
or of any attempt by any other person, firm or corporation, to use the
Subject Matter, the Know-how, the Patent Rights, any Copyrights or any such
other service and/or trademarks, trade names, copyrights licenses hereunder
without the consent of the Licensor, or any other Confidential Material or
trademark, servicemark, symbol, trade name, copyright or variation thereof,
in which the Licensor has a proprietary interest.  The Contractor agrees also
promptly to notify the Licensor of any material litigation instituted by the
Contractor, or by any person, firm, corporation or governmental agency
against the Contractor.  In the event the Licensor, pursuant to the terms of
this Agreement hereinafter set forth, undertakes the defense or prosecution
of any litigation except in the case of the Contractor, the Contractor agrees
to execute any and all documents and do such acts and things which may, in
the opinion of counsel for the Licensor, be necessary or of assistance to
carry out such defense or prosecution, either in the name of the Licensor or
in the name of the Contractor, as the Licensor shall elect and to cooperate
with the Licensor in its efforts to protect the Copyrights, as well as any
trademarks, service marks, trade names, and copyrights described under
Section 2.02.
      7.03  Defense of Patent Rights and Trademarks.
      Notwithstanding any other provision herein, the Licensor does hereby
agree, at its expense, to defend Patent Rights, if any, and the servicemarks
and trademarks herein described by such means as it in its sole discretion
may determine appropriate, including but not limited to, patent or trademark
infringement suits, as the case may be.
      The Licensor reserves, however, the exclusive right to determine
whether a patent arrangement has occurred, and whether a trademark
infringement has occurred, and whether litigation or other action is
appropriate or feasible.  Subject to approval by the Licensor and control by
the Licensor of any and all proceedings initiated as a result thereof, the
Contractor, with its own counsel reasonably acceptable to the Licensor, may,
<PAGE>
at its option and expense, take steps to defend the Patent Rights, any
service mark or trademark and the Contractor's rights thereunder.
      7.04  Indemnification by Contractor
      The Contractor agrees to indemnify, defend and hold the Licensor
harmless from any and all claims, including, without limitation, for bodily
injury (including death), personal injury and damage to property of the
Contractor, the Licensor and/or others, which arise from the alleged
negligence or malfeasance of the Contractor or from the existence or use of
Materials and/or Apparatus acquired from sources other than the Licensor or
which are produced by the Contractor.

ARTICLE VIII - LIMITED ARBITRATION PROCEDURES

      8.00  Limited Arbitration Procedures
      Any controversy or claim arising out of or relating to the subject
matter of this contract, or the breach thereof, shall be submitted to
arbitration in accordance with the rules of the American Arbitration
Association, and the results thereof shall be binding on the parties.

ARTICLE IX - INDEPENDENT CONTRACTORS

      9.00  Independent Contractors.
      This Agreement does not constitute either party as an agent, legal
representative, joint venturer, partner, employee, or servant of the other
party for any purpose whatsoever; and it is understood between the parties
hereto that each party is an independent contractor and is in no way
authorized to make any contract, agreement, warranty or representation on
behalf of the other party, or to create any obligation, express or implied,
on behalf of the other party.  The Contractor shall prominently  display in
its place of business a certificate from the Licensor stating that said
business is operated by the Contractor as a licensee of the Licensor, and not
as an agent thereof.

ARTICLE X - TRANSFER OR ASSIGNMENT OF LICENSE.

      10.00  Transfer or Assignment of License
      Subject to the requirements of the immediately succeeding sentence, the
Contractor, if not in default under this Agreement, shall have the right to
sell and assign its rights hereunder.
      This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns, with the specific
understanding and requirement that the Contractor, without the Licensor's
prior written consent, which consent shall not unreasonably be withheld,
shall not, by operation of law or otherwise, sell, assign, transfer, convey,
subcontract, give away, or encumber to any person, firm or corporation, its
interest in this Agreement, or its interest in the license granted hereby,
nor offer, permit, or suffer the same.  Any such assignment permitted by the
Licensor to any Affiliate of the Contractor shall be made on the express
condition that the assignor guarantees the performance of its assignee
strictly in accordance with the terms and provisions hereof.  In the event
that the Contractor is a corporation or partnership, should beneficial
ownership of an amount of the outstanding capital stock or other interest, as
the case may be, or other indicia of ownership in the Contractor be conveyed
so as to effect a Change in Control of the Contractor, whether by sale,
conveyance, operation of law or otherwise, without having first obtained the
written consent of the Licensor to transfer the license, which consent shall
not unreasonably be withheld, the Licensor shall at its option have the right
to immediately terminate this Agreement or enter into a new Agreement with
the Change in Control.  Any purported assignment, transfer, conveyance or
<PAGE>
subcontract of this Agreement not having the aforesaid consent shall be null
and void and shall constitute a material default hereunder.  If any event has
occurred or fact or circumstances exists which, but for the giving of notice
passage of time or otherwise, would constitute a default hereunder, the
Contractor shall so advise any proposed transferee hereunder.
      Upon approval of any assignment, transfer, or conveyance of the
Agreement by the Licensor, the assignment, transfer, or conveyance shall be
completed without additional License fees or other costs being assessed to
the Contractor.

terms set out in Article X.
      11.03  Exclusivity of License.
      If, despite the Licensor's efforts to maintain the exclusivity of the

reason whatsoever, and the Agreement is continued, but amended, the
Contractor is nevertheless obligated to comply in full with each and every
term and condition of this Agreement, including, but not limited to, the
maintenance of high standards of quality and service.
      11.04  Exclusions.
      It is the intention of the Licensor and the Contractor that the
provisions of this Agreement shall be enforced to the fullest extent
permissible under the laws and public policies of each jurisdiction in which
enforcement is sought, but that the unenforceability of any provisions of
this Agreement shall not render unenforceable, or impair, the remainder of
this Agreement.  In the event that any one or more of the provisions of this
Agreement is, or are, held to be invalid, it is agreed between the parties
that, if legally practical said provision or provisions shall be considered
never to have been contained herein and this Agreement shall otherwise
continue in force and effect.  To the extent that the provisions of this
Agreement provide for periods of notice less than those required by
applicable law, or provide for termination, cancellation, non-renewal or the
like other than in accordance with applicable law, such provisions shall, to
the extent such are not in accordance with applicable law, not be effective,
and the Licensor shall comply with applicable law in connection with each of
these matters.  References in this Agreement to the materiality of any terms
hereof are not intended to be exhaustive of all such material terms, and
shall not preclude any other provision from construction as or constituting a
material provision hereof.
      11.05  Entire Agreement.
      This Agreement constitutes the entire agreement between the parties
hereto with respect to the Subject Matter hereof and supersedes all prior
oral and written understandings and agreements between the parties hereto
concerning the Subject Matter.  The article headings of this Agreement are
for convenience only and have no other significance.  The Provisions of this
Agreement shall not be waived, modified or amended, except by a subsequent
writing signed by both parties.

      11.06  Gender
      Words of the neuter gender utilized in this Agreement shall be deemed
to be of the masculine or feminine gender where the context requires.  Words
of the singular number utilized in this Agreement shall be deemed to be

      11.07  Applicable Law.
      This Agreement shall be governed by and construed in accordance with
the laws of the State of Alabama.
      11.08  Counterparts.
      This Agreement may be executed in counterparts, each of which shall be
deemed an original and both of which or a photocopy thereof shall constitute
one and the same agreement.
      11.09  Standard of Dealing.
      The parties shall perform such further acts and deeds as shall be
necessary to effectuate the purposes of this Agreement and shall, in their
respective performance hereunder, at all times deal in the utmost good faith
with each other.
      11.10  Most Favored Licensee.
      In the event the Licensor subsequently enters into any license
agreement for the Subject Matter in the Permitted Uses within the United
States or its territories, and such license contains terms materially more
favorable to the licensee thereunder than are contained herein with respect
to the Contractor, then at the option of the Contractor, this agreement shall
be amended to incorporate such more favorable terms.
      IN WITNESS HEREOF, THE PARTIES HERETO HAVE CAUSED THIS CONTRACTOR
LICENSE AGREEMENT TO BE SIGNED AND DELIVERED BY THEIR AUTHORIZED

     4.05 Insurance.  The Contractor agrees to procure at its expense, a
policy or policies of insurance from an insurance company or companies
reasonably satisfactory to the Licensor and Contractor's customers, providing
coverage for the operations of the Contractor, including product and
completed operations, with amounts not less than $1,000,000 single limit
liability for injury to persons and damage to property.  The Contractor also
agrees to have the Licensor named as an additional named insured under the
above described policy or policies and to cause the Licensor to be furnished
with a Certificate of Insurance which shall contain a requirement that the
Licensor be notified 30 days prior to any cancellation or any reduction in
coverage or limits.  The insurance requirements above shall commence prior to
the time the Contractor commences operations under this Agreement and shall
continue in force throughout the Term.
     4.06 Taxes; Compliance with Laws.  The Contractor shall promptly pay
when due all taxes and assessments against the premises or the equipment used
in connection with the Contractor's business, and all liens or encumbrances
of every kind or character created or placed upon or against any of said
property, and all accounts and other indebtedness of every kind incurred by
the Contractor in the conduct of said business, the failure to pay which
would have a materially adverse effect on the ability of the Contractor to
perform its obligations hereunder.  The Contractor shall have the right to
contest the validity or amount of any assessment, tax, lien or encumbrance,
provided that the Contractor shall: (1) give the Licensor notice of its
intention to contest; (2) diligently prosecute such contest; and (3) at all
times effectively stay or prevent any official or judicial sale of such
property or any thereof by reason of the non-payment of any lien,
encumbrance, tax, or assessment.  The Contractor shall comply with all
applicable federal, state, county and municipal laws and regulations, now in
effect or hereinafter enacted, including, without limitation, all
environmental laws and all occupational safety and health laws, the failure
to comply with which would have a materially adverse effect on the ability of
the Contractor to perform its obligations hereunder, and shall timely obtain
any and all permits, certificates, or licenses necessary for the full and
proper conduct of its business.
     4.07 Standards and Inspection.  The Contractor shall maintain a high
standard of quality in all installations made and in all other activities
under the Service Mark or Trademark.  To ensure the maintenance of such
standards, the Licensor may periodically inspect the Contractor's practice of
the methods of the Subject Matter at the Licensor's own expense and without
unreasonable inconvenience to the Contractor.  The Contractor shall cooperate
fully with the Licensor in any such inspections in its practices of the
methods of the Subject Matter made by the Licensor.  At all times the
Contractor shall exert diligent effort to practice the methods and techniques
<PAGE>
included in the Subject Matter in accordance with the best available
technical information and advice received from the Licensor.  The Contractor
hereby agrees that failure by the Licensor to exercise any right of
inspection or any other right under this Section 4.08 shall not operate
subsequently to preclude exercise by the Licensor of this right, and that
failure of the Contractor to permit such inspections or to maintain such
standards shall constitute a material breach of this Agreement and shall form
the basis of termination hereof, but solely in accordance with the notice and
cure provisions of Article VI hereof.


ARTICLE V - IMPROVEMENTS; SECRECY

     5.01 Commercialization of Improvements.  The Contractor recognizes and
agrees that from time to time hereafter the Licensor may, in its discretion,

thereto, and that the Contractor, at the election of the Licensor, will
accept, use and display for the purpose of this Agreement any such changes

hereof.  The Contractor shall furnish such cooperation as such changes or
modifications may reasonably require, and do so within a reasonable time.
     5.02 Title to Improvements.
          (a)  The Contractor hereby assigns, and shall cause its
officers, directors, agents, employees and representatives to assign, to the
Licensor the entire right, title and interest in and to any and all
inventions, trade secrets, improvements, plans and specifications (i) which
the Contractor, or its officers, directors, agents, employees or
representatives, alone or in conjunction with others, may make, conceive or
develop during the Term; and (ii) which constitute or derive from the Subject
Matter.  The Contractor further agrees that it will promptly disclose, and
cause its officers, directors, agents employees and representatives promptly

or specification, including, but not limited to, the execution of any and all
applications for copyrights or patents, assignments of copyrights or patents
and other instruments in writing which the Licensor, its officers or
attorneys may deem necessary or desirable, and the aforesaid obligation shall
be binding on the assigns, executors, administrators and other legal
representatives of the Contractor.
          (b)  Without prejudice to any right or remedy available to the
Contractor against third parties, which shall be exercised in consultation
with and subject to the Licensor's approval, which approval shall not
unreasonably be withheld, the Contractor hereby constitutes and appoints the
Licensor the attorney for the Contractor, with full power of substitution,
for it and in its name and stead or otherwise, but at the sole expense and on
behalf of and for the benefit of the Licensor, to institute and prosecute
from time to time, any proceedings at law, in equity or otherwise, that the
Licensor may deem proper in order to assert or enforce any claim, right or
title of any kind in and to the inventions, trade secrets and improvements
described under paragraph (a) immediately preceding, to defend and compromise
any and all actions, suits or proceedings in respect of any said inventions,
trade secrets and improvements, and, generally to do any and all such acts
<PAGE>
and things in relation thereto as the Licensor shall deem advisable,
including, but not limited to, the execution of any and all applications,
assignments and instruments contemplated under such paragraph.  The
Contractor declares that the appointment hereby made and the powers hereby
granted are coupled with an interest and shall be irrevocable by the
undersigned.
          (c)  The Licensor hereby agrees that, during the Term, it shall
be obliged to disseminate at no charge to all of its licensees, for their
mutual benefit to be used subject to the terms of their respective license
agreements, such of its inventions, trade secrets, plans, specifications,
improvements or modifications which are necessary to utilize the System.
     5.03 Secrecy.  Each Receiving Party shall, and shall instruct all of
its officers, directors, employees, agents or representatives to, hold in
absolute secrecy and treat confidentially all Confidential Material of a
Disclosing Party, and not disclose, reproduce, publish, distribute or by any
other means disseminate, in whole or in part, any such Confidential Material,
except as shall be specifically necessary for the Receiving Party to disclose
such Confidential Material to its employees in order to exercise its rights
under this Agreement.  Neither the Receiving Party nor any of its employees,
agents or representatives may in any manner use for its benefit or for the
benefit of others any such Confidential Material except as shall be
specifically necessary for the Receiving Party to exercise its rights
authorized under this Agreement.
     5.04 Remedies.
          (a)  Without in any manner limiting the obligation of either
party to cause its officers, directors, agents, employees and representatives
to comply with the provisions of Section 5.02 and 5.03 hereof, as applicable,
each party shall cause each of its officers, directors and key employees to
execute an agreement in a form prescribed by Licensor and, except as set
forth in the next succeeding sentence, all other employees which have access
to Confidential Material or information constituting or derived from the
Subject Matter to execute an agreement in any form prescribed by Licensor.
          (b)  In view of the irreparable harm and damage which would be
incurred by a party in the event of any violation by the other party or any
of its officers, directors, employees, agents or representatives of any of
the provisions of Sections 5.02 or 5.03 hereof, as applicable, each party
hereby consents and agrees that, if it or any of its officers, directors,
employees, agents or representatives violate any such provision, the other
party shall be entitled to an injunction or similar equitable relief to be
issued by any court of competent jurisdiction restraining the said party and
its employees, agents and representatives from committing or continuing any
such violation.
          (c)  The provisions of Sections 5.02 and 5.03 and 5.04 shall, in
accordance with their respective terms, survive the Term and this Agreement,
notwithstanding any termination or expiration thereof.  Without limiting the
generality of any other provision hereof, each party shall enforce the
provisions of such sections insofar as they relate to its employees, agents
and representatives; provided, however, that neither party shall be liable
for the acts of its employees, agents and representatives which are not
within the scope of their employment.


ARTICLE VI - TERMINATION

     6.01 Termination by Contractor.  The Contractor may terminate this
Agreement at any time by service of written notice to such effect on the
Licensor 30 days in advance of the effective date thereof and by complying
with the applicable terms and conditions of this Article VI.  During such
period after notice but prior to actual termination, the Contractor shall not
<PAGE>
bid or accept any additional jobs (except those outstanding bids with bid
bonds that have not been awarded) which will require the utilization of the
Subject Matter from the Licensor under the Patent Rights or the Know-How
without the written consent of the Licensor, which consent shall not
unreasonably be withheld.
     6.02 Termination by Licensor.
          (a)  This Agreement and the rights of the Contractor hereunder
may be terminated by the Licensor in the event the Contractor:
               (i)   becomes insolvent or a petition in bankruptcy is
filed by or against the Contractor and not removed within 20 days thereafter,
or a receiver is appointed for the Contractor; or
               (ii)  utilizes the Subject Matter in any application
outside of the Permitted Uses; or
               (iii) fails to achieve the Performance Objectives
described in Section 4.03 hereof in a particular Contract Year, without an
excuse provided by this agreement.
               (iv)  fails to pay when validly due any sum owed to
Licensor or any of its Affiliates arising from or in connection with this
Agreement and such failure shall continue for a period of 30 days after
written notice from the Licensor to the Contractor; or
               (v)   fails to perform any other material term or
condition of this Agreement and fails to correct the same within 30 days
after written notice from the Licensor to the Contractor, or if not
reasonably capable of correction within such period, fails to commence such
correction within such period and thereafter fails to diligently proceed to
make such correction; or
               (vi)  fails to submit and deliver to the Licensor any
written report required under paragraph (a) of Section 3.05 hereof when due
and such failure shall continue for a period of 30 days after written notice
from the Licensor to the Contractor.
          (b)  In the event the Contractor fails to pay the License Fee or
any Cross-Over Payment in accordance with Article III hereof, or fails to
provide any written report required under paragraph (b) of Section 3.05
hereof in accordance with such provision and, in the case of the first such
breach in any calendar year, such failure shall continue for a period of 30
days after written notice from the Licensor to the Contractor, then in any
such event, this Agreement shall automatically terminate.
          (c)  No termination under this Section 6.02 shall limit or
affect any other right or remedy of the Licensor, including the right to
damages resulting from the Contractor's breach.
     6.03 Consequences of Expiration or Termination.
          (a)  Upon expiration or termination of this Agreement, the
Contractor shall promptly pay the Licensor all amounts then due under this
Agreement, terminate all use by it of any service mark, tradename, trademark,
certification mark or corporate name that includes any of the foregoing
words; avoid all subsequent use of all service marks, tradenames, trademarks,
certification marks or corporate names likely to be confused with ULTRALINER
as well as all stationery, invoices, signs or other visual devices displaying
or otherwise associated with ULTRALINER; terminate all use of the Subject
Matter and the Licensor's Confidential Material, as well as the use and sale
of any products under any Patent Rights or Copyrights or the Know-how; and
assign to the Licensor free of charge, any and all rights and claims to any
and all rights arising from the use of ULTRALINER, or any combination
involving ULTRALINER, the above mentioned Corporate rights in the Territory;
and return to the Licensor all Confidential Material in its possession, and
any copies which it has made of the same.  Following termination, the
Contractor shall continue to be obligated to provide all after sales services
for which it has theretofore contracted, including the honoring of all
<PAGE>
contract warranties.  Should the Contractor fail to fulfill such obligations,
and should the Licensor, in its reasonable discretion after notice to the
Contractor, whether for reason of preserving product goodwill or otherwise,
choose to perform any such obligations (this paragraph in no way to be
construed as an assumption by the Licensor of any obligations for which it is
not specifically contractually responsible), then the Contractor shall
promptly reimburse the Licensor the reasonable charges issued by the Licensor
to the Contractor of performing such obligations of the Contractor.  If the
Contractor is a corporation having the word ULTRALINER as a part of its
corporate name, the Contractor shall, within 60 days of termination, amend
its corporate name to remove the word ULTRALINER therefrom.
          (b)  Each party hereto shall promptly pay to the other party all
damages, costs and expenses, including reasonable attorney's fees, incurred
by such other party by reason of default on the part of such party hereto,
whether or not such default occurred prior to or subsequent to the
termination or expiration of this Agreement, and said sum shall include all
costs and expenses, including reasonable attorney's fees, incurred by such
other non-defaulting party in obtaining injunctive or other relief to enforce
the provisions of this Agreement.  Notwithstanding the foregoing, in any
dispute under this agreement, the ultimate prevailing party shall be entitled
to recover from the other party its reasonable attorney's fees.  No right or
remedy herein conferred upon or reserved to either party is exclusive of any
other right or remedy herein or by law or equity provided or permitted; but
each shall be cumulative of every right or remedy given hereunder.  In
addition to whatever remedy or remedies a party may have by way of damages
for violation of the provisions of this Agreement and/or expiration or
termination of the same, such party shall also have the right to injunctive
relief to enforce the provisions of this Agreement.
          (c)  In the event of the termination of this Agreement by the
Licensor or Contractor as a consequence of any event described under sub-
paragraphs (i), (iii), or (vi) of Paragraph (a) of Section 6.02 or 6.01
hereof, the Licensor shall thereafter assist the Contractor in disposing of
any Materials or Apparatus then in the possession of the Contractor,
including but not limited to the sale of excess inventory to other qualified
Licensees, subject in such case to the constraints of the Licensor's business
and its other obligations.
          (d)  Licensor shall supply to the Contractor, at the current
rates and prices, any and all materials or apparatus Contractor may need to
complete any outstanding projects or projects that may have been bid prior to
the termination, but not awarded, and a bid bond was provided by the
Contractor, provided the Contractor is not in default of any provision of
Section 6.02.

ARTICLE VII - WARRANTIES; INDEMNIFICATION

     7.01 Limited Subject Matter Warranty.
          (a)  The Licensor represents and warrants that the Product can
successfully rehabilitate many types of sewer (sewerage and storm) and water
pipelines within the Permitted Uses when installation is properly performed. 
Every reasonable precaution will be taken by the Licensor in compiling all
data, and offering instructions in the methods of use of the Product
purchased from the Licensor for operation hereunder, to assure compliance
with the Licensor's exacting standards and that the use of the Subject Matter
for the Permitted Uses in accordance with the terms and conditions of this
Agreement maintains a high standard of quality.  To the best of the
Licensor's knowledge, all information given will be correct in all material
respects.  However, it is impossible to anticipate every possible variation
in the manner of use or the conditions under which the Contractor will apply
the Product and Licensor makes no warranty or representation of results which
<PAGE>
the Contractor will attain, and, except as stated above, shall under no
circumstances be held responsible for any such results that occur as a
consequence of a departure from the instructions provided by the Licensor or
from negligence or malfeasance on the part of the Contractor.
          (b)  Licensor does warrant that the Product will comply with
Licensor's standard specifications and will perform in the Permitted Uses as
described herein and for a period of one year, or as may be required by
customers for a particular project, from the date of sale will not fail in
the performance in such uses on account of manufacturing defects.  In the
event of any such failure, the liability of the Licensor shall be limited to
the replacement of the product that has failed.

THE FOREGOING WARRANTY IS IN LIEU OF AND EXCLUDES ALL OTHER WARRANTIES NOT
EXPRESSLY SET FORTH HEREIN, WHETHER EXPRESSED OR IMPLIED BY OPERATION OF LAW
OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY OF FITNESS
FOR ANY PURPOSE OTHER THAN AS IS CONTEMPLATED BY THIS AGREEMENT.
          LICENSOR SHALL NOT BE LIABLE FOR EXEMPLARY, PUNITIVE, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF
PROFITS OR REVENUES, LOSS OF USE OF GOODS OR EQUIPMENT, DAMAGE TO PROPERTY,
COST OF CAPITAL, COST OF SUBSTITUTION OF GOODS OR COVER, LIQUIDATED DAMAGES,
CLAIMS BY PURCHASERS FROM CONTRACTOR.  LICENSOR'S LIABILITY TO CONTRACTOR IS
LIMITED TO REPLACEMENT OF GOODS NOT COMPLYING WITH THE AGREEMENT, OR, AT
LICENSOR'S ELECTION, TO THE REFUNDING OR CREDITING OF THE PRICE PAID FOR THE
GOODS, WHETHER THE CLAIM ASSERTED IS IN CONTRACT OR TORT.
          (c)  The Licensor makes no representation nor warranty that
ULTRALINER PVC ALLOY (Trade Mark) or ULTRALINER PVC ALLOY PIPELINER (Trade
Mark) or ULTRALINER PVC ALLOY PIPELINER SYSTEM (Trade Mark) is available for
use as a service mark, tradename, trademark, and/or certificate mark in the
United States.
     Further, except as expressly set forth in this Article VII, the
Licensor shall not be held responsible for use by the Contractor of any
Product, Materials, Apparatus, Know-how, Patents Rights or Confidential
Material in such manner as to infringe any patent, trademark or copyright
owned by another.  The Licensor warrants that it has rights to the patents
pertaining to the Materials subject to no lien, encumbrance or charge
whatsoever.
     7.02 Forbearance by Contractor. The Contractor expressly covenants
that during the Term and after the expiration or termination thereof, the
Contractor shall not, directly or indirectly, contest or aid in contesting
the validity, or the ownership or licensing by the Licensor, of the Subject
Matter, the Know-how, any Patent Rights and any Copyrights, as well as any
trademarks, service marks, trade names, and copyrights described under
Section 2.02, or the limitation of the Contractor's right with respect to the
Subject Matter by the terms and provisions of this Agreement.  The Contractor
agrees promptly to notify the Licensor of any claim, demand, suit or
litigation based upon or arising from, or of any attempt by any other person,
firm or corporation, to use the Subject Matter, the Know-how, the Patent
Rights, any Copyrights or any such other service and/or trademarks, trade
names, copyrights licenses hereunder without the consent of the Licensor, or
any other Confidential Material or trademark, servicemark, symbol, trade
name, copyright or variation thereof, in which the Licensor has a proprietary
interest.  The Contractor agrees also promptly to notify the Licensor of any
material litigation instituted by the Contractor, or by any person, firm,
corporation or governmental agency against the Contractor.  In the event the
Licensor, pursuant to the terms of this Agreement hereinafter set forth,
undertakes the defense or prosecution of any litigation except in the case of
the Contractor, the Contractor agrees to execute any and all documents and do
such acts and things which may, in the opinion of counsel for the Licensor,
<PAGE>
be necessary or of assistance to carry out such defense or prosecution,
either in the name of the Licensor or in the name of the Contractor, as the
Licensor shall elect and to cooperate with the Licensor in its efforts to
protect the Copyrights, as well as any trademarks, service marks, trade
names, and copyrights described under Section 2.02.
     7.03 Defense of Patent Rights and Trademarks.  Notwithstanding any
other provision herein, the Licensor does hereby agree, at its expense, to
defend Patent Rights, if any, and the servicemarks and trademarks herein
described by such means as it in its sole discretion may determine
appropriate, including but not limited to, patent or trademark infringement
suits, as the case may be.
     The Licensor reserves, however, the exclusive right to determine
whether a patent infringement has occurred, and whether a trademark
infringement has occurred, and whether litigation or other action is
appropriate or feasible.  Subject to approval by the Licensor and control by
the Licensor of any and all proceedings initiated as a result thereof, the
Contractor, with its own counsel reasonably acceptable to the Licensor, may,
at its option and expense, take steps to defend the Patent Rights, any
service mark or trademark and the Contractor's rights thereunder.
     7.04 Indemnification by Contractor.  The Contractor agrees to
indemnify, defend and hold the Licensor harmless from any and all claims,
including, without limitation, for bodily injury (including death), personal
injury and damage to property of the Contractor, the Licensor and/or others,
which arise from the alleged negligence or malfeasance of the Contractor or
from the existence or use of Materials and/or Apparatus acquired from sources
other than the Licensor or which are produced by the Contractor


ARTICLE VIII - LIMITED ARBITRATION PROCEDURES

     8.00 Any controversy or claim arising out of or relating to the
subject matter of this contract, or the breach thereof; shall be submitted to
arbitration in accordance with the rules of the American Arbitration
Association, and the results thereof shall be binding on the parties.


ARTICLE IX - INDEPENDENT CONTRACTORS

     9.00 Independent Contractors.  This Agreement does not constitute
either party as an agent, legal representative, joint venturer, partner,
employee, or servant of the other party for any purpose whatsoever; and it is
understood between the parties hereto that each party is an independent
contractor and is in no way authorized to make any contract, agreement,
warranty or representation on behalf of the other party, or to create any
obligation, express or implied, on behalf of the other party.  The Contractor
shall prominently display in its place of business a certificate from the
Licensor stating that said business is operated by the Contractor as a
licensee of the Licensor, and not as an agent thereof.


ARTICLE X - TRANSFER OR ASSIGNMENT OR LICENSE.

     10.00 Subject to the requirements of the immediately succeeding
sentence, the Contractor, if not in default under this Agreement, shall have
the right to sell and assign its rights hereunder.
<PAGE>
This Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and assigns, with the specific
understanding and requirement that the Contractor, without the Licensor's
prior written consent, which consent shall not unreasonably be withheld,
shall not, by operation of law or otherwise, sell, assign, transfer, conveys
subcontract, give away, or encumber to any person, firm or corporation, its
interest in this Agreement, or its interest in the license granted hereby,
nor offer, permit, or suffer the same.  Any such assignment permitted by the
Licensor to any Affiliate of the Contractor shall be made on the express
condition that the assignor guarantees the performance of its assignee
strictly in accordance with the terms and provisions hereof.  In the event
that the Contractor is a corporation or partnership, should beneficial
ownership of an amount of the outstanding capital stock or other interest, as
the case may be, or other indicia of ownership in the Contractor be conveyed
so as to effect a Change in Control of the Contractor, whether by sale,
conveyance, operation of law or otherwise, without having first obtained the
written consent of the Licensor to transfer the license, which consent shall
not unreasonably be withheld, the Licensor shall at its option have the right
to immediately terminate this Agreement or enter into a new Agreement with
the Change in Control.  Any purported assignment, transfer, conveyance or
subcontract of this Agreement not having the aforesaid consent shall be null
and void and shall constitute a material default hereunder.  If any event has
occurred or fact or circumstance exists which, but for the giving of notice
passage of time or otherwise, would constitute a default hereunder, the
Contractor shall so advise any proposed transferee hereunder.  Upon approval
of any assignment, transfer, or conveyance of the Agreement by the Licensor,
the assignment, transfer, or conveyance shall be completed without additional
License fees or other costs being assessed to the Contractor.


ARTICLE XI - MISCELLANEOUS

     11.1 Notices.  Any notice required or permitted to be given or served
upon either party hereto pursuant to this Agreement shall be sufficiently

inure to the benefit of the parties hereto and their respective successors
and assigns, subject to the term set out in Article X.
     11.03 Exclusivity of License.  If, despite the Licensor's efforts to
maintain the exclusivity of the license granted hereunder, such exclusivity
should be terminated for any reason whatsoever, and the Agreement is
continued, but amended, the Contractor is nevertheless obligated to comply in
full with each and every term and condition of this Agreement, including, but
not limited to, the maintenance of high standards of quality and service.
     11.04 Exclusions.  It is the intention of the Licensor and the
Contractor that the provisions of this Agreement shall be enforced to the
fullest extent permissible under the laws and public policies of each
jurisdiction in which enforcement is sought, but that the unenforceability of
any provisions of this Agreement shall not render unenforceable, or impair,
the remainder of this Agreement.  In the event that any one or more of the
provisions of this Agreement is, or are, held to be invalid, it is agreed
between the parties that, if legally practical said provision or provisions
shall be considered never to have been contained herein and this Agreement
shall otherwise continue in force and effect.  To the extent that the
provisions of this Agreement provide for periods of notice less than those
required by applicable law, or provide for termination, cancellation, non-
<PAGE>
renewal or the like other than in accordance with applicable law, such
provisions shall, to the extent such are not in accordance with applicable
law, not be effective, and the Licensor shall comply with applicable law in
connection with each of these matters.  References in this Agreement to the
materiality of any terms hereof are not intended to be exhaustive of all such
material terms, and shall not preclude any other provision from construction
as or constituting a material provision hereof.
     11.05 Entire Agreement.  This Agreement constitutes the entire
agreement between the parties hereto with respect to the Subject Matter
hereof and supersedes all prior oral and written understandings and
agreements between the parties hereto concerning the Subject Matter.  The
article headings of this Agreement are for convenience only and have no other
significance.  The Provisions of this Agreement shall not be waived, modified
or amended, except by a subsequent writing signed by both parties.

shall be deemed to be of the masculine or feminine gender where the context
requires.  Words of the singular number utilized in this Agreement shall be
deemed to be plural where the context requires and vice versa.
     11.07 Applicable Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of Alabama.
     11.08 Counterparts.  This Agreement may be executed in counterparts,
each of which shall be deemed an original and both of which or a photocopy
thereof shall constitute one and the same agreement.
     11.09 Standard of Dealing.  The parties shall perform such further acts
and deeds as shall be necessary to effectuate the purposes of this Agreement
and shall, in their respective performance hereunder, at all times deal in
the utmost good faith with each other.
     11.10 Most Favored Licensee.  In the event the Licensor subsequently
enters into any license agreement for the Subject Matter in the Permitted
Uses within the United States or its territories, and such license contains
terms materially more favorable to the licensee thereunder than are contained
herein with respect to the Contractor, the, at the option of the Contractor,
this agreement shall be amended to incorporate such more favorable terms.


     IN WITNESS HEREOF, THE PARTIES HERETO HAVE CAUSED THIS CONTRACTOR

      See SECTION 26 for continuation of PAYMENT SCHEDULE.

SECTION 5.  TIME
            ----

      work in a prompt and diligent manner in accordance with Contractor's
      progress schedule, without delaying or hindering Contractor's work or
      the work of other contractors or subcontractors.  Subcontractor shall
      coordinate the work covered by this Agreement with that of all other
      contractors, subcontractors, and of the Contractor, in a manner that

                                                     DPR Job No.: 09-9600140
                                           Subcontract No. 09-96001-00-048-S
                                                   Cost Code: See Section 26

      will facilitate the efficient completion of the entire work.  In the
      event Subcontractor fails to maintain its part of the Contractor's
      schedule, it shall, without additional compensation, accelerate the
      work as Contractor may direct until Subcontractor's work is in
      accordance with such schedule.  Contractor shall have complete control
      of the premises on which the work is to be performed and shall have the
      right to decide the time and order in which various portions of the
      work shall be installed and the relative priority of the work of 
      Subcontractor and other subcontractors, and, in general, all other
      matters pertaining to the timely and orderly conduct of the work of
      Subcontractor on the premises.  Should Subcontractor be delayed in the
      prosecution or completion of the work by the act, neglect or default of
      Owner, Architect or Contractor; or should Subcontractor be delayed
      waiting for materials, if required by this Contract to be furnished by
      Owner or Contractor; or by damage caused by fire or other casualty for
      which Subcontractor is not responsible; or by the combined action of
      the workmen, in no way caused by or resulting from fault or collusion
      on the part of Subcontractor; or in the event of a lock-out by
      Contractor; then the time herein fixed for the completion of the work
      shall be extended by the number of days that Subcontractor has thus
      been delayed.  But no allowance or extension shall be made unless a
      claim therefor is presented in writing to Contractor within 48 hours of
      the commencement of such delay, and under no circumstances shall the
      time of completion be extended to a date which will prevent Contractor
      from completing the entire project within the time allowed Contractor
      by Owner for such completion.

      No claims for additional compensation or damages for delays, whether
      caused in whole or in part by any conduct on the part of Contractor,
      including, but not limited to, conduct amounting to a breach of this
      Agreement, or delays by other subcontractors or Owner shall be
      recoverable from Contractor, and the above-mentioned extension of time
      for completion shall be the sole remedy of Subcontractor; provided,
      however that in the event Contractor obtains additional compensation
      from Owner on account of such delays, and in the event Subcontractor
      shall have satisfied all subcontract and contract requirements with
      respect to timely notification and assertion of claims and with respect
      to cooperation with Contractor in the prosecution therewith,
      Subcontractor shall be entitled to such portion of the additional
      compensation so received by Contractor from Owner as is deemed by the
      Contractor to be equitable under all of the existing and applicable
      circumstances.  In no event shall compensation to Subcontractor for
      delay damages exceed that which Contractor receives from Owner on
      Subcontractor's behalf.  In the event that Contractor prosecutes a
      claim against Owner for additional compensation for any delay,
      Subcontractor shall cooperate fully with Contractor in the prosecution
      thereof and shall pay costs and expenses incurred in connection
      therewith, including actual attorneys' fees, to the extent that said
      claim is made by Contractor at the request of Subcontractor.

      Subcontractor shall prepare and obtain approval as required by the
      Contract Documents for all shop drawings details, samples, and do all
      other things necessary and incidental to the prosecution of its work in
      conformance with Contractor's progress schedule.

      See SECTION 26 for additional TIME provisions.<PAGE>

SECTION 6.  CHANGES IN THE WORK
            -------------------

      Subcontractor shall make any and all changes in the work described in
      the Contract Documents and this Agreement as directed by Contractor in
      writing.  Such change or written direction shall not invalidate this
      Agreement.

      If necessary, the contract price stated in Section 3 and the time for
      Subcontractor's performance shall be adjusted by appropriate additions
      or deductions mutually agreed upon before Subcontractor performs the
      changed work.  Subcontractor shall supply Contractor with all
      documentation necessary to substantiate the amount of the addition to
      or deduction from the price or time.  If Contractor and Subcontractor
      cannot agree on the amount of the addition or deletion.  Subcontractor
      shall nonetheless timely perform the work as changed by Contractor's
      written direction.  Once Subcontractor receives Contractor's written
      direction, Subcontractor is solely responsible for timely performance
      of the work as changed by the written direction.  In any event,
      Subcontractor's compensation for changes in the work shall be limited
      to that which Contractor receives from Owner on Subcontractor's behalf.

      Payment for changed work shall be made in accordance with Section 4.

      Subcontractor shall not make any changes in the work described in
      Section 2 or in any way cause or allow that work to deviate from the
      Contract Documents without written direction from Contractor.  If
      Subcontractor makes any changes in the work described in Section 2
      without written direction from Contractor, such change constitutes an
      agreement by Subcontractor that it will not be paid for that changed
      work, even if it received verbal direction from Contractor or any form
      of direction, written or otherwise, from Owner or any other person or
      entity.  In addition, Subcontractor shall be liable for any and all
      losses, costs, expenses, damages, and liability of any nature
      whatsoever associated with or in any way arising out of any such change
      it makes without written direction from Contractor.

      If a dispute arises between Contractor and Subcontractor about whether
      particular work is a change in the work described in Section 2,
      Subcontractor shall timely perform the disputed work and may give
      written notice of a claim for additional compensation for that work. 
      Such written notice of claim must be given within ten (10) days after
      such work is performed.  Subcontractor's failure to give written notice
      within the ten (10) days constitutes an agreement by it that it will
      not be paid for the disputed work.

      No change, alteration, or modification to or deviation from this
      Agreement, the Contract Documents, prime contract, plans, or
      specifications, whether made in the manner provided in this provision
      or not, shall release or exonerate, in whole or in part, any bond or
      any surety on any bond given in connection with this Agreement, and no
      notice is required to be given to such surety of any such change,
      alteration, modification, or deviation.

SECTION 7.  DAMAGES CAUSED BY DELAYS OF SUBCONTRACTOR
            -----------------------------------------

      If Subcontractor should default in performance of the work described in
      Section 2 or should otherwise commit any act which causes delay to the
      prime contract work, Subcontractor shall be liable for all losses,
      costs, expenses, liabilities and damages, including consequential
      damages and liquidated damages, sustained by Contractor, or for which
      Contractor may be liable to Owner or any other party because of
      Subcontractor's default.

SECTION 8.  BONDING OF SUBCONTRACTOR
            ------------------------

      performance bond, in an amount equal to one hundred percent (100%) of
      the Contract Price.  Said bonds shall be executed by a corporate surety
      acceptable to Contractor and shall be in a form satisfactory to
      Contractor.  Contractor shall pay the premium on said bonds unless
      otherwise provided herein or in the Contract Documents.

      decision of the court in said suit Subcontractor agrees within ten (10)
      days after written demand to cause the effect of any such suit or lien
      to be removed from the premises, and in the event Subcontractor shall
      fail so to do.  Contractor is authorized to use whatever means in its
      discretion it may deem appropriate to cause said lien or suit to be
      removed or dismissed and the cost thereof, together with actual
      attorneys' fees, shall be immediately due and payable to Contractor by
      Subcontractor. Subcontractor may litigate any such lien or suit
      provided it causes the effect thereof to be removed, promptly in
      advance, from the premises, and shall further do such things as may be
      necessary to cause Owner not to withhold any monies due to Contractor
      from Owner by reason of such liens or suits.

      It is understood and agreed that the full and faithful performance of
      this Agreement on the part of Subcontractor including the payment of
      any obligations due from Subcontractor to Contractor, and any amounts
      due to labor or materialmen finishing labor or material for said work)
      is a condition precedent to Subcontractor's right to receive payment
      for the work performed, and any monies paid by Contractor to
      Subcontractor under the terms of this Agreement shall be impressed with
      a trust in favor of labor and materialmen furnishing labor and material
      to Subcontractor on the work herein subcontracted.

       satisfactorily continue correction of a default within forty-eight

       Attachment 4, Subcontractor Billing Package, attached hereto is made a
       part of this Subcontract.  Additionally, DPR's billing procedures are
       amended as follows: DPR Construction, Inc.'s standard Billing
       Procedures will be used by Subcontractors for all payment
       applications.  ADDITIONALLY, the Subcontractor is notified that all
       Payment Applications submitted must be accompanied by the
       Subcontractor's Certified Payroll and a schedule of values for the pay
       period covered by the payment application.  The Certified Payroll must
       be attested to by a principal of the firm, the Subcontractor's
       accountant or other authorized representative.  The Subcontractor is
       made aware that all certified payrolls are subject to audit at such
       frequency as may be determined by DPR.  Further, the Subcontractor
       will be required to configure and code all schedules of values,
       payment requests and invoices as may be directed by DPR prior to their
       submittal for payment.  Payment for all materials stored offsite is
       solely at the discretion of DPR and, if allowed, requires the
       execution by the Subcontractor of DPR's "Agreement for the Payment of
       Stored Materials/Bill of Sale & Agreement to Protect", without
       exception.

                         PROMISSORY NOTE
                                                  March 17, 1997
$2,500,000 Maximum                                Roanoke, Virginia


     FOR VALUE RECEIVED, the undersigned, ETS INTERNATIONAL, INC., a
Virginia corporation ("Maker"), promises to pay to the order of THOMAS W.
MARMON, as Trustee of the THOMAS W. MARMON TRUST ("Payee"), the principal
amount equal to the aggregate amount of advances made by Payee to Maker
hereunder, which advances shall not exceed Two Million Five Hundred Thousand
Dollars ($2,500,000), together with interest at the rate of Twenty-Five
Thousand Dollars ($25,000) per month, regardless of the principal balance
from time to time outstanding.

     Maker shall make monthly interest payments to Payee of $25,000 in
installments commencing April 17, 1997, and on the 17th day of each month
thereafter until March 17, 1999, at which time the remaining balance of
principal and interest shall be paid in full; provided, however, that Payee
shall have the option to call this Note in full at any time upon sixty (60)
days written notice (i.e., Payee has the option to accelerate the entire
principal and interest owing and demand payment in full upon sixty (60) days
written notice).  The Maker reserves the right to pre-pay this Note at any
time upon sixty (60) days written notice to Payee.

     Late Charge.  If any installment of principal or interest is not paid
within ten (10) days of its due date, Maker will forthwith pay to the holder
of this Note a late charge in an amount equal to five percent (5%) of the
past due payment.  This is in addition to the holder's other rights and
remedies for default in payment of an installment of interest when due. 
Maker will pay this late charge promptly, but only once on each late payment.

     Security.  This Note and all obligations of Maker hereunder are secured
by certain security agreements and a guaranty of even date herewith, and any
and all security agreements, guaranties, mortgages, pledge agreements,
assignments, and all other agreements and instruments heretofore or hereafter
given by Maker or any third party to Payee ("Security Documents"), including,
but not limited to, Security Documents given in connection with or referred
to in any prior promissory notes given to Payee by any Maker and Security
Documents that secure any present or future guaranty of all or part of the
indebtedness evidenced by this Note.  Payee shall have all of the rights and
powers set forth in the Security Documents and in any other written
agreements heretofore or hereafter given to Payee by Maker, as though they
were fully set forth herein.  As additional security for the payment of
Maker's obligations under this Note, Maker grants to Payee a security
interest in all tangible and intangible property of Maker now or hereafter in
the possession of Payee.

     Default and Acceleration.  Each of the following shall be an event of
default under this Note: (a) if default occurs in the payment of any
installment of principal or interest hereunder or of any late charge or out-
of-pocket expense at any time owing to Payee under this Note or in the
payment of any other indebtedness or obligation now or hereafter owing by
Maker to Payee, as and when the same shall be or become due and payable and
such failure shall continue unremedied for a period of ten (10) days; (b) if
default occurs in the performance of any other obligation to Payee under this
Note or any Security Document or any other agreement heretofore or hereafter
entered into between Maker and Payee or if there occurs any other event of
<PAGE>
default under any Security Document or any such other agreement, and any such
default shall continue unremedied for a period of ten (10) days after the
sending of written notice of such default to Maker; (c) if any warranty or
representation heretofore or hereafter made to Payee by Maker or any
guarantor of all or part of the Indebtedness evidenced by this Note
("Guarantor"), in any Security Document or in any financial statement or
other document given to Payee in connection with this Note, shall have been
false in any material respect; (d) if Maker or any Guarantor, shall dissolve,
become insolvent, or make an assignment for the benefit of creditors; (e) if
any guaranty that now or hereafter secures payment of all or any part of the
indebtedness evidenced by this Note shall be terminated or limited for any
reason without the written consent or agreement of the holder of this Note;
(f) if any part of the principal or interest of, or any other payment of
money due under, any indebtedness for borrowed money of the Maker, including
without limitation any indebtedness to banks or other financial institutions,
is not paid when due or within any grace period; (g) if any indebtedness of
Maker (including without limitation any indebtedness to banks or other
financial institutions) becomes or is declared to be due and payable prior to
the stated maturity thereof as a result of any default or event of default
occurring with respect thereto; or (h) if at any time the holder of this Note
for any reason shall in good faith believe that the prospect of payment or
performance of this Note or any other indebtedness or obligation of Maker to
the holder is impaired.  Upon the occurrence of any event of default, all or
any part of the indebtedness evidenced hereby and all or any part of all
other indebtedness and obligations then owing by Maker to the holder shall,
at the option of the holder, become immediately due and payable without
notice or demand.  If a voluntary or involuntary case in bankruptcy,
receivership, or insolvency shall at any time be instituted by or against
Maker or any Guarantor and, in the case of an involuntary action, such action
is not discharged within thirty (30) days thereafter, or if any levy, writ of
attachment, garnishment, execution, or similar process shall be issued
against or placed upon any property of Maker or Guarantor, then all such
indebtedness shall automatically become immediately due and payable.  All or
any part of the indebtedness' evidenced hereby also may become, or may be
declared to be, immediately due and payable under the terms and conditions
contained in any Security Document.

     Place and Application of Payments.  Each payment upon this Note shall
be made to Payee at the following address: Thomas W. Marmon as Trustee of the
Thomas W. Marmon Trust, c/o Ceres Corporation, 4390 Airwest Drive SE, Grand
Rapids, Michigan 49512 or at such other place as the holder hereof may direct
in writing.  Any payment upon this Note shall be applied first to any
expenses (including expenses of collection) then due and payable to Payee
hereunder, then to any unpaid late charges, then to any accrued and unpaid
interest hereunder, and then to the unpaid principal balance.  If Maker at
any time owes the holder of this Note any indebtedness or obligation in
addition to the indebtedness evidenced by this Note, and if any indebtedness
owed by Maker to the holder is then in default, Maker shall have no right to
direct or designate the particular indebtedness or obligation upon which any
payment made by, or collected from, Maker or from any Guarantor or other
security shall be applied.  Maker hereby waives any such right and agrees
that the manner of application of any such payment, as between or among such
indebtedness and obligations, shall be determined solely by the holder.

     Setoff.  The holder of this Note shall have the right at any time to
set off any indebtedness that the holder then owes to Maker against any
indebtedness evidenced by this Note that is then due and payable.
<PAGE>
     Remedies.  The holder of this Note shall have all rights and remedies
provided by law and by agreement of Maker.  Any requirement of reasonable
notice with respect to any sale or other disposition of collateral shall be
met if the holder sends the notice at least 5 days prior to the date of sale
or other disposition.  Maker agrees to pay any and all expenses, including
reasonable attorney fees and legal expenses, paid or incurred by the holder
in protecting and enforcing the rights of and obligations to the holder under
any provision of this Note or any Security Document.

     Environmental Compliance.  Maker represents and warrants to, and agrees
with, Payee that: (a) none of Maker's real or personal property is, and Maker
will not permit it to become, unlawfully contaminated by any substance that
is now or hereafter regulated by or subject to any present or future law or
regulation that establishes liability for the removal or clean-up of, or
damage caused by, any environmental contamination; (b) Maker's operations,
activities, and real and personal properties are, and Maker shall cause them
to continue to be, in compliance with each such law and regulation in all
material respects; (c) if the indebtedness evidenced by this Note is not paid
at maturity, then at any time thereafter the holder of this Note may, but
shall not be obligated to, conduct or obtain an environmental investigation
or audit of any or all of Maker's properties, and Maker shall reimburse the
holder for all costs and expenses incurred by the holder in connection with
the investigation or audit, and (d) Maker shall indemnify and hold harmless
the holder with respect to all claims, damages, losses, liabilities, and
expenses (including reasonable attorney fees) asserted against or incurred by
the holder by reason of any failure to comply with, or any inaccuracy in, any
of the agreements, representations, and warranties contained in this
paragraph.

     Waivers.  No delay by the holder of this Note in the exercise of any
right or remedy shall operate as a waiver thereof.  No single or partial
exercise by the holder of any right or remedy shall preclude any other or
future exercise thereof or the exercise of any other fight or remedy.  No
waiver by the holder of any default or of any provision hereof shall be
effective unless in writing and signed by the holder.  No waiver of any right
or remedy on one occasion shall be a waiver of that right or remedy on any
future occasion.

     Maker waives demand for payment, presentment, notice of dishonor, and
protest of this Note and consents to any extension or postponement of time of
its payment, to any substitution, exchange, or release of all or any part of
any security given to secure this Note, to the addition of any party hereto,
and to the release, discharge, waiver, modification, or suspension of any
rights and remedies against any person who may be liable for the indebtedness
evidenced by this Note.

     Maker agrees that the interest rate on this Note is not usurious, and
Maker waives any defense or cause of action related to usury.

     Advances.  Payee will advance $2,000,000 to Maker upon execution of
this Note.  Maker from time to time may request additional advances (up to
$2,500,000 outstanding at anytime).  Any such additional advances shall be
made by Payee in his sole and unlimited discretion upon review of Maker's
financial condition and the value of collateral securing this Note.

     General.  In this Note, "maturity" means such time as the entire
remaining unpaid principal balance shall be or shall become due and payable
for any reason, including acceleration as provided above.
<PAGE>
     Applicable Law and Jurisdiction.  This Note shall be governed by and
interpreted according to the laws of the Commonwealth of Virginia, without
giving effect to principles of conflict of laws.  Maker irrevocably agrees
and consents that any action against Maker for collection or enforcement of
this Note may be brought in any state or federal court that has subject
matter jurisdiction and is located in, or whose district includes, Kent
County, Michigan, and that any such court shall have personal jurisdiction
over Maker for purposes of such action.

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

                              Address:  1401 Municipal Road, N.W.
                                        Roanoke, Virginia 24012
<PAGE>

                                  GUARANTY

      THIS GUARANTY is given as of the 17th day of March, 1997, by
GUARANTORS, as hereafter defined, in favor of THOMAS W. MARMON, as Trustee of
the THOMAS W. MARMON TRUST, with a mailing address of Thomas W. Marmon,
Trustee of the Thomas W. Marmon Trust, c/o Ceres Corporation, 4390 Airwest
Drive SE, Grand Rapids, Michigan 49512 ("Marmon"), pursuant to a loan made by
Marmon to ETS INTERNATIONAL, INC., a Virginia corporation ("Borrower"). 
Guarantors are wholly-owned direct or indirect a subsidiaries of Borrower.

      1.    Guarantors.  As used in this Guaranty, "Guarantors" means,
collectively, the undersigned corporations, and every reference to
"Guarantors" in this Guaranty shall mean each such corporation individually. 
Each of the undersigned corporations is jointly and severally liable for the
payment of the Indebtedness (as defined below) under this Guaranty.

      2.    Guaranty.  In consideration of any credit heretofore or hereafter
extended by Marmon to Borrower, Guarantors hereby absolutely,
unconditionally, and irrevocably guarantee prompt payment when due, and at
all times thereafter, of (i) any and all existing and future indebtedness,
obligations, and liabilities of Borrower to Marmon under a certain note of
even date herewith executed by Borrower in favor of Marmon, and (ii) any and
all renewals, extensions, replacements and modifications of that note and all
interest, late charges and reasonable expenses accrued thereon (collectively
the "Indebtedness").  The Indebtedness also includes any and all indebtedness
and obligations now or hereafter owing to Marmon by Borrower, regardless of
whether any such indebtedness or obligation is (i) not presently intended or
contemplated by Borrower, Marmon or Guarantors; (ii) indirect, contingent or
secondary; or (iii) unrelated to, or of a different kind of class from, any
indebtedness or obligations of Borrower to Marmon that are now owing or are
committed or contemplated.

      3.    Unlimited Liability.  Except as provided by Paragraph 12, each
Guarantor's liability for the payment of the Indebtedness under this Guaranty
is unlimited.

      4.    Expenses.  Guarantors shall reimburse Marmon for all costs,
reasonable attorney fees, and other expenses at any time expended or incurred
by Marmon in the collection or attempted collection of the Indebtedness or in
the enforcement of this Guaranty or the realization upon any security now or
hereafter granted for this Guaranty.

      5.    Unconditional.  The effectiveness of this Guaranty is not subject
to the satisfaction of any conditions, including, without limitation, the
signing of this or another guaranty, or the granting of any other security,
by any person, firm or corporation.  Marmon may grant or continue credit from
time to time to Borrower without notice to or authorization from Guarantors,
regardless of Borrower's financial or other condition at the time of any such
grant or continuation.  Marmon shall have no obligation to disclose or
discuss with Guarantors his assessment of Borrower's financial condition. 
The execution of this Guaranty by Guarantors, however, shall create no
obligation or duty of Marmon to grant or continue credit to Borrower.
<PAGE>
      6.    Application of Payments.  Marmon in its sole discretion may,
without affecting, impairing, or reducing Guarantors' obligations under this
Guaranty, (i) apply payments or collections received from any source to the
payment of indebtedness other than the Indebtedness, even though Marmon could
have applied those payments to the Indebtedness; and (ii) apply payments or
collections received from Guarantors or from any present or future security
for this Guaranty to any liability of Guarantors under this Guaranty or to
any liability of Guarantors for payment to Marmon of any other indebtedness. 
Any payments or collections that Marmon applies to the liability of
Guarantors under this Guaranty shall be applied to costs or expenses
described in Paragraph 4 above and to the components of the Indebtedness, all
in such manner as Marmon in its sole discretion shall determine.

      7.    Rights Against Debtor.  Guarantors will not exercise or enforce,
and hereby waive, any right of contribution, reimbursement, recourse, or
subrogation available to Guarantors against Borrower or any other person
liable for payment of all or part of the Indebtedness, or as to any security
therefor, unless and until all of the Indebtedness is paid in full and
discharged.

      8.    Warranties and Representations.  Each Guarantor warrants and
represents to Marmon that (i) all financial statements and other information
concerning such Guarantor furnished to Marmon are true and correct in all
material respects; (ii) the execution, delivery, and performance of this
Guaranty by such Guarantor has been validly authorized by all necessary
corporate action of its board of directors and/or shareholders and will not
violate its articles of incorporation or bylaws or any law, rule, judgment,
order, agreement, or instrument binding it, nor require the approval of any
public authority or other third party; and (iii) this Guaranty constitutes
the valid and binding obligation of such Guarantor and is enforceable in
accordance with its terms.

      9.    Waivers.  Guarantors waive (i) notice of the acceptance of this
Guaranty and of the extension or continuation of all or any part of the
Indebtedness; (ii) presentment, protest, notice, demand, or action with
respect to any default in payment of all or any part of the Indebtedness and
with respect to any default by any Guarantor in its obligations under this
Guaranty; and (iii) any right to require Marmon to sue Borrower, any other
Guarantor or any other person obligated with respect to all or any part of
the Indebtedness or to foreclose or realize upon any security for all or any
part of the Indebtedness.  Guarantors waive any and all defenses, claims, and
discharges of Borrower or any other obligor with respect to the Indebtedness,
except the defense of discharge by payment.  Without limiting the generality
of the foregoing, Guarantors will not assert, plead, or enforce against
Marmon any defense of waiver, release, discharge in bankruptcy, statute of
limitations, res judicata, statute of frauds, anti-deficiency statute, fraud, 
incapacity minority, usury, ultra vires, lack of authorization, illegality,
or unenforceability that may be available to Borrower or any other person
liable in respect of any Indebtedness or any setoff available against Marmon
to Borrower or any such other person, whether or not on account of a related
transaction.  Guarantors shall be liable for any deficiency remaining after
foreclosure of or realization upon any security for all or part of the
Indebtedness, whether or not the liability of Borrower or any other obligor
for the deficiency is discharged pursuant to statute or judicial decision.
<PAGE>
      10.   Termination or Revocation.  This Guaranty shall continue in
effect until receipt by Marmon of written notice of its termination or
revocation and, notwithstanding that receipt, thereafter as to Indebtedness
incurred, arising, or committed for prior to receipt by Marmon of notice of
termination or revocation.  A notice of revocation or termination must be in
writing, shall not be effective until received by Marmon and shall be
effective only as to the Guarantor giving the notice, and this Guaranty shall
remain in effect as to the other Guarantors not giving the notice.

      11.   No Impairment of Guaranty.  The validity and enforceability of
this Guaranty shall not be impaired or affected by any of the following
(whether occurring before or after receipt by Marmon of notice of termination
of this Guaranty) with respect to all or part of the Indebtedness or any
agreement relating thereto or with respect to any present or future guaranty
or other security for all or part of the Indebtedness: (i) any extension,
modification, renewal, indulgence or substitution; (ii) any failure or
omission to enforce any right, power, or remedy; (iii) any waiver of any
right, power, or remedy or of any default; (iv) any release, surrender,
compromise, settlement, subordination, or modification, with or without
consideration; (v) the unenforceability or invalidity of the Indebtedness or
of any present or future guaranty for all or part of the Indebtedness; (vi)
any failure by Marmon to perfect or secure any priority of its rights with
respect to any security; or (vii) any consent by Marmon to any sale or
transfer of any security; all whether or not the undersigned shall have had
notice or knowledge of any act, omission, or circumstance referred to in this
Paragraph.

      12.   Enforceability.  If any one or more provisions of this Guaranty
should be invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions contained herein
shall not in any way be affected, impaired, prejudiced or disturbed thereby. 
If at any time any portion of the obligations of any Guarantor under this
Guaranty shall be determined by a court of competent jurisdiction to be
invalid, unenforceable or avoidable, the remaining portion of the obligations
of that Guarantor under this Guaranty shall not in any way be affected,
impaired, prejudiced or disturbed thereby and shall remain valid and
enforceable to the fullest extent permitted by applicable law.  If at any
time all or any portion of the obligations of any Guarantor under this
Guaranty would otherwise be determined by a court of competent jurisdiction
to be invalid, unenforceable or avoidable under Section 548 of the U.S.
Bankruptcy Code or under a similar applicable law of any jurisdiction
(including without limitation laws relating to fraudulent conveyances or
fraudulent transfers), then notwithstanding any other provisions of this
Guaranty to the contrary that obligation or portion thereof of that Guarantor
under this Guaranty shall not exceed (a) the maximum amount which could be
incurred hereunder by that Guarantor without rendering this Guaranty void or
unenforceable under applicable law relating to fraudulent conveyance,
fraudulent transfer or the like after taking into account the probability of
that Guarantor making any payment pursuant to this Guaranty, the amount of
such probable payment, and all consideration and value directly or indirectly
received by that Guarantor from Marmon or the Borrower as a result of Marmon
making loans and other financial accommodations to the Borrower now or
hereafter, less (b) one dollar.  If any Guarantor claims that its liability
hereunder is subject to the foregoing limitation, then that Guarantor agrees
that it has the burden of proof as to all matters pertaining to that
limitation in light of the fact that it has possession of all the financial
information needed to determine the amount of such limitation.
<PAGE>
      13.   Independence of Obligations.  The liability of Guarantors
hereunder is independent of any other guaranties or obligations at any time
in effect with respect to all or any part of the Indebtedness and may be
enforced regardless of the existence, validity, enforcement, or
nonenforcement of any such other guaranties or other obligations.  Marmon is
authorized to release or modify the obligations of or surrender any security
given by or waive any rights against Borrower or any Guarantor, without in
any manner affecting or impairing the liability of the other Guarantors.

      14.   Return of Payments.  If any payment applied by Marmon to the
Indebtedness is set aside, recovered, rescinded, or required to be returned
for any reason (including, without limitation, the bankruptcy, insolvency, or
reorganization of Borrower, any Guarantor, or any other person liable in
respect of any Indebtedness), the Indebtedness to which the payment was
applied shall for the purposes of this Guaranty be deemed to have continued
in existence, notwithstanding the application, and this Guaranty shall be
enforceable as to such Indebtedness as fully as if Marmon had not made the
application.

      15.   Applicable Law, Venue, Jurisdiction.  This Guaranty and the
rights and obligations of the parties shall be governed by and interpreted in
accordance with the laws of the Commonwealth of Virginia, without giving
effect to principles of conflicts of laws.  Guarantors irrevocably agree and
consent that any action against Guarantors for collection or enforcement of
this Guaranty may be brought in any state or federal court that is located in
or whose jurisdiction includes Kent County, Michigan, and that any such court
shall have jurisdiction over Guarantors for that action.

      16.   Complete Agreement.  This Guaranty contains the entire agreement
between Guarantors and Marmon with respect to the subject matter hereof. 
There are no promises, terms, conditions, or obligations other than those
contained herein.  This Guaranty may not be modified except by writing signed
by the party to be charged. 

       17.  Notices.  Any notices or communications required or permitted
under this Guaranty shall be in writing and shall be deemed given when served
either personally or by certified United States mail (postage prepaid), or by
overnight express courier, addressed to Guarantors at their respective
addresses set forth below, and to Marmon at its address set forth on the
first page of this Guaranty, or to such other place as a party shall
designate by notice served upon the other parties in accordance with this
Paragraph.

      18.   Binding Effect.  This Guaranty shall be binding upon and shall
inure to the benefit of Marmon and Guarantors and their respective successors
and assigns.  Marmon may assign this Guaranty in connection with an
assignment of all or any portion of the Indebtedness.

      19.   Security.  Guarantors acknowledge that their obligations under
this Guaranty are secured by those security agreements of even date herewith
between each Guarantor and Marmon.

      20.   Corporate Benefit.  Each Guarantor is a wholly-owned direct or
indirect subsidiary of Borrower and will therefore derive substantial direct
and indirect benefits from the extensions of credit by Marmon to Borrower. 
Accordingly, this Guaranty is necessary and convenient to the conduct,
promotion and attainment of the business of Borrower and is in furtherance of
the corporate purposes of each Guarantor.

      IN WITNESS WHEREOF, Guarantors have executed and delivered this
Guaranty as of the date first above written.

13.2  Demonstration Unit and Special right of Termination

      a.    Licensor and Licensee agrees to equally contribute resource and
            equally assume the potential risks and profits to build the first
            commercialized demo unit.

      b.    In order to quickly complete the first commercialized demo unit,
            the demo unit might have to be built first and collect money
            after the system is accepted by the potential client.

      c.    The size of the first demo unit should be close to 10 MW scale
            and the budget of the total cost should be under US$400,000. 
            Licensor and Licensee shall work out details on how to build the
            first demo unit and set all the terms and conditions in another
            separate agreement.

      f.    In case the demo system fails and the money cannot be collected,
            Licensor and Licensee shall assume their own loss&

      g.    If the plan of building first demo unit cannot be executed
            because of Licensor's withdraw, Licensee has the right to
            terminate the License agreement and Licensor shall return the
            total up-front payment paid by Licensee to Licensor within 30
            days after receiving Licensee's terminating notice if Licensee
            chooses to terminate the agreement.
<PAGE>

      h.    If the plan of building first demo unit cannot be executed not
            because of Licensor's faults, Licensee cannot ask Licensor to
            return any up-front payment paid by Licensee to Licensor
            regardless whether Licensee chooses to continue or terminate the
            agreement.

      i.    Either ETS or E&C has the right to ask the opposite side for
            reconsidering whether the proceeding of the Demo-unit project is
            necessary or not if an LEC system (8MW or larger) is sold and
            proved effective operation in Taiwan before the demonstration
            project is initiated.

      j.    If until the end of the third year after this agreement is
            signed, the Demo unit project still cannot be executed because of
            faults of neither the Licensor nor the Licensee, then both sides
            have the right to ask the opposite side for terminating this
            agreement three months before this agreement expired, and the
            Licensee cannot ask the Licensor for returning the up-front
            payment of this agreement.

      k.    The sales guarantee includes all the sales conducted by Licensee
            regardless the sales destination.

      l.    The agreement is a five year base, and will be evaluated by both
            parties each year from the end of the third year after the
            agreement signed.

      rights in law and equity of either party hereto.

            equally assume the potential risks and profits to build the first
            commercialized demo unit.

      b.    In order to quickly complete the first commercialized demo unit,
            the demo unit might have to be built first and collect money

            separate agreement.

      d.    Selling price and terms of the first demo unit will be determined
            according to the negotiation with the potential clients.

      e.    Once the demo unit is accepted by the client and money is
            collected, the profits will be shared equally by licensor and
            licensee.

      f.    In case the demo system fails and the money cannot be collected,

            total up-front payment paid by Licensee to Licensor within 30
            days after receiving Licensee's terminating notice if Licensee
            chooses to terminate the agreement.

<PAGE>
      h.    If the plan of building first demo unit cannot be executed not
            because of Licensor's faults, Licensee cannot ask Licensor to
            return any up-front payment paid by Licensee to Licensor
            regardless whether Licensee chooses to continue or terminate the
            agreement.

      i.    Either ETS or E&C has the right to ask the opposite side for
            reconsidering whether the proceeding of the Demo-unit project is
            necessary or not if an LEC system (8MW or larger) is sold and
            proved effective operation in Taiwan before the demonstration
            project is initiated.

      j.    If until the third year after this agreement is signed, the Demo
            unit project still cannot be executed because of faults of
            neither the Licensor nor the Licensee, then both sides have the
            right to ask the opposite side for terminating this agreement
            three months before this agreement expired, and the Licensee
            cannot ask the Licensor for returning the up-front payment of
            this agreement.

      k.    The sales guarantee includes all the sales conducted by Licensee
            regardless the sales destination.

      l.    The agreement is a five year base, and will be evaluated by both
