Item 1.  Business.
- ------   --------

         Overview
         --------

         ETS International, Inc. ("ETSI"), a Virginia corporation formed in
         1987, is a technology-based firm that historically has provided both
         environmental and construction products and services.  During the
         second half of fiscal 1998, ETSI made a determination to focus on
         its construction lines of business and to de-emphasize its
         environmental products and services.  Specifically, ETSI is
         directing its efforts to the development and growth of its existing
         underground infrastructure products and services related to the
         installation and rehabilitation of subsurface pipelines using
         trenchless technologies.  Trenchless technology involves the
         installation and rehabilitation of underground pipelines with
         minimal surface disruption.  Some of the methods used are pipe
         relining, manhole construction and "pipe bursting."

         As part of its refocusing effort, ETSI has, since October 1997,
         undertaken a major management reorganization, sold substantially all
         of the assets of its two environmental related subsidiaries,
         relocated its corporate headquarters to Richmond, Virginia, where
         ETSI's construction subsidiary is based, changed the names of
         certain of its subsidiaries to reflect ETSI's emphasis on
         infrastructure and, subject to shareholder approval, intends to
         change the name of ETSI to InfraCorps Inc.  ETSI also changed its
         fiscal year-end from May 31 to March 31.  See "Recent Developments"
         below.  
<PAGE>
         ETSI operates its infrastructure business through two wholly-owned
         affiliates:  InfraCorps of Virginia, Inc. (formerly ETS Water and
         Waste Management, Inc.) ("ETSW") and InfraCorps of Florida, Inc.
         (formerly ETS Liner, Inc.) ("ETSL"), a subsidiary of ETSW.  In
         connection with its restructuring, ETSI during fiscal 1998 sold
         substantially all of the assets of IC Subsidiary, Inc. (formerly
         ETS, Inc.) ("ETS") and ETS Analytical Services, Inc. ("ETSAS"), as
         described below.  As a result of these sales, neither ETS nor ETSAS,
         which are wholly-owned subsidiaries of ETSI, currently is engaged in
         active business operations. 

         InfraCorps of Virginia, Inc. (formerly ETS Water and Waste
         Management, Inc.) ("ETSW"), a Virginia corporation headquartered in
         Richmond, Virginia, is ETSI's construction subsidiary.  ETSW was
         formed as a result of ETSI's acquisition on June 1, 1994, of Stamie
         E. Lyttle Company, Inc., Lyttle Utilities, Inc. and LPS Corporation. 
         The three firms, the history of which dates back to 1947, were
         consolidated into one corporation, ETSW.  ETSW, along with its
         subsidiary, InfraCorps of Florida, Inc. (formerly ETS Liner, Inc.)
         ("ETSL"), a Virginia corporation headquartered in Orlando, Florida,
         utilizes trenchless technologies to install and rehabilitate
         subsurface pipelines.  ETSI's infrastructure customers include
         municipalities, government agencies, Fortune 500 companies and
         developers.  ETSW, through its Service Division, also designed and
         installed septic and irrigation systems and provided related repair
         and maintenance services.  As part of ETSI's effort to focus on the
         infrastructure business, ETSI, in April 1998, sold the Service
         Division of ETSW to a new corporation formed by Coleman S. Lyttle, a
         director of ETSI and President of ETSW. 

         IC Subsidiary, Inc. (formerly ETS, Inc.) ("ETS"), a Virginia
         corporation, was ETSI's environmental products and services
         subsidiary.  On March 12, 1998, ETSI completed the sale of
         substantially all of the assets of ETS to ETS Acquisition, Inc.  In
         connection with the sale, ETSI sold a portion of its assets and
         liabilities relating to the Limestone Emission Control ("LEC")
         technology, including patents and licenses, to Christel Clear
         Technologies, Inc. ("CCTI").  Both ETS Acquisition and CCTI are
         newly formed entities owned by John D. McKenna, Arthur B. Nunn, III
         and John C. Mycock, former executive officers and former directors
         of ETSI.  

         ETS Analytical Services, Inc.  ("ETSAS"), a Virginia corporation,
         operated as the environmental analytical laboratory subsidiary of
         ETSI.  In October 1997, ETSI sold substantially all of the assets of
         ETSAS to Q Enterprises, Inc., a company owned by James B. Quarles, a
         former employee and Senior Vice President of ETSI.  Mr. Quarles has
         since become President and Chief Executive Officer of ETSI and sold
         his interest in Q Enterprises, Inc. 

         ETSI's principal executive offices are located at 7400 Beaufont
         Springs Drive, Suite 415, Richmond, Virginia 23225, and its
         telephone number is (804) 272-6600.

         Recent Developments
         -------------------

         On January 20, 1998, ETSI announced a management reorganization,
         pursuant to which James B. Quarles was elected President and Chief
         Executive Officer of ETSI and was appointed to its Board of
<PAGE>
         Directors.  Navin D. Sheth, the Chief Operating Officer of ETSW, a
         wholly owned subsidiary of ETSI, was appointed Chief Financial
         Officer of ETSI.  John D. McKenna resigned as President and Chief
         Executive Officer of ETSI on that date.  Further, in connection with
         on-going negotiations to purchase substantially all the assets of
         ETSI's wholly owned environmental subsidiary, ETS, John D. McKenna,
         Arthur B. Nunn, III and John C. Mycock resigned from ETSI's Board of
         Directors effective February 2, 1998.  These resignations were not
         the result of a disagreement on any matter relating to ETSI's
         operations, policies or practices.  In light of these resignations,
         James B. Quarles was elected Chairman of the Board, in addition to
         his position as President and Chief Executive Officer. 

         The management reorganization reflects ETSI's intention to focus on
         its infrastructure lines of business and to de-emphasize its
         environmental products and services.  New management believes that
         the environmental services aspect of ETSI historically has been a
         break-even business, providing little value to shareholders, while
         attempts to commercialize the environmental technologies aspect of
         ETSI have been a drain on ETSI's limited capital resources. 
         Management believes that ETSI should focus on one line of business
         -- the installation and rehabilitation of subsurface pipelines for
         the transmission of water, waste and natural gas -- and is seeking
         to position ETSI to take advantage of perceived growth opportunities
         within that industry segment.  There can, however, be no assurance
         that the Company's refocusing efforts will be successful. 

         ETSI is seeking shareholder approval at its Annual Meeting of
         Shareholders, to be held on August 17, 1998, to formally change its
         name to InfraCorps Inc.  Pending shareholder approval of the formal
         name change, ETSI has filed a fictitious name certificate to conduct
         business in Virginia as InfraCorps Inc.  On April 9, 1998, ETSI
         relocated its headquarters to Richmond, Virginia, where its
         construction subsidiary, ETSW, is based.  Effective May 22, 1998,
         ETSI changed the names of its wholly owned subsidiaries, ETSW and
         ETS, to InfraCorps of Virginia, Inc. and IC Subsidiary, Inc.,
         respectively.  The name of ETSL was changed to InfraCorps of
         Florida, Inc. effective May 21, 1998.  

         On October 31, 1997, ETSI sold substantially all of the assets and
         certain liabilities of ETSAS to Q Enterprises, Inc., a company owned
         by James B. Quarles, a former employee and Senior Vice President of
         ETSI.  Mr. Quarles has since become President and Chief Executive
         Officer of ETSI and sold his interest in Q Enterprises, Inc.  Since
         the risks of ownership were not transferred to Q Enterprises, Inc.,
         no sale was recognized for accounting purposes.  Accordingly, the
         assets and liabilities transferred to Q Enterprises, Inc. are shown
         in the noncurrent sections of the balance sheet and are designated
         as "assets of business transferred under contractual arrangements"
         and "liabilities of business transferred under contractual
         arrangements."  ETSI received an 8.5% promissory note in the amount
         of $1,000,000 with payments amortized over 30 years with a balloon
         payment after 10 years.  As payments of principal and interest are
         received, they are being recorded as a reduction to "assets of
         business transferred under contractual arrangements" until such time
         as ETSI determines a sale can be recorded for accounting purposes. 
         At March 31, 1998, "assets of business transferred under contractual
         arrangements" of $267,666 are stated net of a valuation allowance of
         $858,000.  The conversion of these assets to cash is dependent on
         the future profitable operations of Q Enterprises, Inc.  A loss on
<PAGE>
         disposal of these discontinued environmental operations of $878,326
         was recorded.

         On March 6, 1998, ETSI Common Stock was removed from listing and
         registration on the AMEX-EMC because ETSI was unable to achieve
         compliance with the EMC continued listing guidelines.  ETSI's Common
         Stock currently is quoted on the OTC Bulletin Board under the symbol
         ETSI.

         On March 12, 1998, substantially all of the assets of ETS were sold
         to ETS Acquisition, Inc., a newly formed firm based in Roanoke,
         Virginia.  In connection with this sale, ETSI sold a portion of its
         assets and business relating to the LEC technology, including
         patents and licenses, to CCTI, a newly formed firm based in Roanoke,
         Virginia.  The total purchase price was approximately $1,896,000 for
         all of the aforementioned.  The purchase price was paid in cash,
         stock of ETSI, assumption of certain liabilities of ETS, delivery of
         a 30-day note bearing 8 1/2% interest and delivery of a 10-year note
         bearing 8 1/2% interest, and ETSI will receive 50% of all royalties
         received by CCTI in connection with the license of the LEC
         technology.  While there is no indication that the LEC will be
         resold by CCTI, the agreement further provides that ETSI will
         receive 50% of the net sales price from a resale of the LEC
         technology on or before March 12, 1999, and 25% of the net sales
         price from a resale after March 12, 1999 but on or before March 12,
         2000.  A loss on disposal of these discontinued environmental
         operations of $513,547 was recorded.

         In connection with the foregoing transaction, ETSI entered into a
         Management Agreement with Air Technologies, Inc. ("ATI"), a newly
         formed firm based in Roanoke, Virginia, to provide management
         services with respect to ETSI's contract to supply to China Steel
         Corporation sulfur dioxide removal systems utilizing the LEC
         technology (the "CSC Contract").  ETS Acquisition, Inc., CCTI and
         ATI are owned by John D. McKenna, Arthur B. Nunn, III and John C.
         Mycock, three former executive officers of ETSI and former members
         of ETSI's Board of Directors. 

         ATI and CCTI have agreed to accept responsibility for any potential
         liabilities associated with the CSC Contract and to provide their
         best efforts to have the CSC Contract assigned without recourse from
         ETSI to ATI.  However, although negotiations are underway with China
         Steel Corporation, ETSI has not yet been successful in obtaining
         assignment of the CSC Contract.  Accordingly, ETSI still has
         potential liability under the CSC Contract which could have a
         material negative impact on ETSI's business operations.  Potential
         issues have been brought to current management's attention regarding
         the budget to meet certain of the performance specifications of the
         CSC Contract and the overall viability of the LEC technology for
         wide-scale commercialization.  If the LEC technology does not meet
         contract specifications, China Steel Corporation may seek to impose
         financial penalties or attempt to recover damages or obtain other
         relief under the CSC Contract, including drawing down on the
         $600,000 performance bond posted by ETSI.   

         Business Segment Information
         ----------------------------

         During the ten-month period ended March 31, 1998 ("fiscal 1998"),
         ETSI and its wholly owned affiliates provided both environmental and
         infrastructure products and services.  Prior to fiscal 1998 year-
<PAGE>
         end, ETSI disposed of its environmental operations segments.  Moving
         forward, ETSI intends to specialize in infrastructure design,
         construction and maintenance utilizing trenchless technologies to
         install and rehabilitate subsurface pipelines.
         
         Services and Products
         ---------------------

         Trenchless technology refers to a family of methods, materials and
         equipment that can be used for installation of new or rehabilitation
         of existing underground pipelines.  These methods provide minimal
         disruption to surface traffic, business and other activities, as
         opposed to open trenching and its associated major disruptions to
         surface activities. 

         Both ETSW and ETSL utilize a so-called "fold and formed" trenchless
         technology.  Under this technology, a robotic vehicle with lights
         and a video traverses the damaged line to detect blockage, offset
         joints and other impediments.  Any remedial work is then performed
         within the existing lines, either through a point repair from the
         surface or through a remote device.  The pipe liner, which is
         constructed specifically for the job and which is folded to fit
         within the existing host pipeline, is inserted so that it extends
         through the damaged length of pipe.  The length of each pipe is at
         least the distance from manhole to manhole.  Insertion is made
         through a power wench and steel cable connected to the end of the
         pipe liner.  Through the application of steam heat and pressure, the
         pipe liner expands to fit the inside of the host pipe.  The fit is
         so tight that it leaves no annular space for unwanted water
         migration between the pipeliner and the host pipe.  The new smooth
         interior maintains peak flow and inhibits build-up of foreign
         material.  The life of the replacement liner is the same as new
         pipe.

         ETSW is a party to a contract license agreement (the "License
         Agreement") with Ultraliner, Inc. ("Ultraliner"), under which ETSW
         has the exclusive right and license to use the ULTRALINER PVC ALLOY
         (Trademark) deformed pipeline technology and process developed by
         Ultraliner for the restoration, repair and rehabilitation of water
         and sewer (sewage and storm) pipelines in the geographical area
         lying within the principal boundaries of the counties of Frederick,
         Clarke, Loudoun, Alexandria, Warren, Fauquier, Prince William, Page,
         Rappahannock, Madison, Culpeper, Stafford, King George, Orange,
         Spotsylvania, Caroline, Essex, Westmoreland, Richmond, Louisa,
         Hanover, King William, King & Queen, Fluvanna, Goochland, Henrico,
         New Kent, Cumberland, Powhatan, Amelia, Shenandoah and Chesterfield,
         Virginia, and the cities of Hopewell, Colonial Heights, Richmond and
         Winchester, Virginia (the "Territory").  Under the License
         Agreement, Ultraliner retains the right to grant exclusive licenses
         to other parties in the Territory to utilize the Ultraliner product
         and services for purposes other than the repair, rehabilitation and
         reconstruction of water or sewer pipelines.  The License Agreement
         terminates on February 1, 2001, and is renewable by ETSW for an
         additional five-year term, subject to termination in the event of
         specific defaults, including the failure of ETSW to meet certain
         minimum performance objectives.  After payment of an initial license
         fee, no further royalties are due under the License Agreement. 
         However, if ETSW seeks to utilize the Ultraliner technology outside
         of the Territory, whether or not in an area where a license for such
<PAGE>
         permitted use has been granted by Ultraliner, ETSW must make an
         immediate Cross-Over Payment of 25% of the gross product price of
         all product sold outside of the Territory.  All Cross-Over Payments
         must be paid by ETSW to Ultraliner, as agent for ETSW, which then in
         turn will promptly pay 20% of the Cross-Over Payment to the licensee
         in whose territory the installation is performed, if any.  All
         licenses governing the commercialization of the Ultraliner product
         within the United States provide for similar Cross-Over payments. 
         In fiscal 1998, ETSW comprised approximately 89.5% of ETS's
         infrastructure business.

         ETSL historically has operated under a contract license agreement to
         use the Ultraliner technology and process throughout most of the
         State of Florida, but is currently transitioning its operations to
         another "fold and formed" licensor.  In May, 1998, ETSL, which in
         fiscal 1998 accounted for approximately 10.5% of ETS's
         infrastructure business, entered into a sub-license agreement with
         Miller Pipeline Corporation ("Miller") to become an exclusive sub-
         licensee to use the "EX," "EX Method" and "EX Pipe" service marks
         and related technology and process in water, sewer and industrial
         process pipelines. ETSL's territory under the sublicense agreement
         is defined as the State of Florida, excluding the counties of
         Apalachicola River, Jackson, Calhoun, Gulf, Holmes, Washington, Bay,
         Walton, Okaloosa, Santa Rosa and Escambia (the "ETSL Territory"). 
         Under the sub-license agreement, if ETSL's capacity does not permit
         it to install or buy a minimum of 75,000 feet of the EX Method pipe
         in any twelve-month period, Miller has the right to terminate the
         exclusive nature of the sub-license agreement and to grant a
         nonexclusive sub-license to another entity in the ETSL Territory. 
         The sub-license agreement terminates on March 31, 2004, and is
         renewable for an additional five-year term, subject to termination
         in the event of specific defaults.  After payment of the initial
         license fee, ETSL must pay a royalty of 7% of the net sales price of
         the internal pipelining completed and billed using the EX Method
         technology and all directly associated work.  

         ETSL historically has not had profitable operations and is being
         closely monitored by management of ETSI.  If profitability is not
         achieved by ETSL relatively soon, it may be divested.

         Suppliers and Licenses
         ----------------------

         ETSI's materials and equipment are generally available from several
         suppliers.  However, ETSI believes that Ultraliner is presently the
         sole source of proprietary Ultraliner material and, therefore, ETSW
         is presently dependent upon Ultraliner for its supply of Ultraliner
         material.  During the last three years, ETSW has not experienced any
         difficulty in obtaining adequate supplies of Ultraliner tube
         material.  Similarly, ETSL is required to use Miller as its sole
         source of supply in the ETSL Territory in connection with its EX
         Method sub-license.  Miller may, on a quarterly basis, adjust the
         price of materials based on the manufacturers' potential variation
         of the raw pipe materials from a base cost of pound of PVC.  ETSL
         currently has no reason to believe that obtaining necessary
         materials and supplies from Miller will be a problem.  

         Because of the availability of alternate or similar trenchless
         technology process, ETSI management does not believe that the loss
         of the current licenses by ETSW or ETSL would be material to ETSI's
         business operations.  See "Competition" below.<PAGE>

         Revenue Recognition, Contract Awards and Backlog
         ------------------------------------------------

         ETSI recognizes revenues using the percentage-of-completion method. 
         The installation process generally is performed between manholes or
         similar access points within a twenty-four hour period.  A
         rehabilitated pipeline section is considered completed work and is
         generally billable to the customer.  In most cases, contracts
         consisting of individual line sections have a duration of less than
         one year.  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.  

         The backlog on infrastructure contracts for the ten-month period
         ended March 31, 1998, was approximately $5,527,124, as compared to
         $4,770,106 for the ten-month period ended March 31, 1997.  See
         "Current Projects" below.

         Customers
         ---------

         During fiscal 1998, ETSI, through ETSW and ETSL, performed
         infrastructure services under contracts with governmental
         authorities, private industries and commercial entities.  In each of
         the last three fiscal years, more than 35% of ETSI's infrastructure
         revenues came from state and local government entities -- cities,
         counties, state agencies and regional authorities.  For the ten-
         month period ended March 31, 1998, ETSI had infrastructure contract
         revenues from five customers, each of which accounted for more than
         5% of contract revenues, aggregating approximately $4,718,000 or 37%
         of contract revenues.  These customers included two municipalities
         and three commercial entities.  At March 31, 1998, four customers
         had accounts receivable balances which exceeded 5% of the trade
         accounts receivable balance.  The accounts receivable balances for
         these customers totaled $883,854. 

         Municipal Activities.  In order to bid for municipal construction
         services in Virginia, 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 government 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
<PAGE>
         invited by the municipalities themselves to bid on specific
         projects.  ETSW selects the projects that it desires to bid based on
         its 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 of 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.  ETSL engages
         in similar bidding processes with respect to municipal construction
         in the State of Florida.

         Commercial Construction.  ETSW also performs services for developers
         and corporations.  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
         environmental requirements.
         
         Competition
         -----------

         The general pipeline reconstruction, rehabilitation and repair
         business is highly competitive.  ETSI faces competition both from
         contractors employing traditional methods of pipeline replacement
         and repairs and from contractors offering alternative trenchless
         products and technologies.  

         The Ultraliner and other "fold and formed" processes compete with
         traditional methods of pipe rehabilitation, including full
         replacement, point of repair and sliplining.  ETSI believes that the
         "fold and formed" process usually offers a cost advantage over full
         replacement, as well as the practical advantage of avoiding
         excavation.  In addition, the "fold and formed" process also offers
         qualitatively better rehabilitation than traditional sliplining,
         which may significantly reduce the diameter of the pipe.  Grouting
         is also undertaken in the United States.  ETSI considers grouting a
         short-term repair technique and not a long-term pipeline
         rehabilitation solution competitive with the "fold and formed"
<PAGE>
         process.  As a practical matter, competition for ETSI typically
         begins at the point that an end-user has determined to employ
         trenchless technology over traditional rehabilitation methods
         involving substantial excavation.  

         ETSI competes with alternative trenchless technologies, such as
         cured-in-place pipeline rehabilitation.  ETSI is aware of a number
         of other trenchless technologies both under development and from
         time to time introduced into the market place with mixed results. 
         ETSI believes that it can compete successfully with these
         alternative trenchless products.

         The principal areas of competition in general pipeline
         reconstruction, rehabilitation and repair include the quality of the
         work performed, the ability to provide a long-term solution to the
         pipeline problems rather than a short-term repair, the amount of
         disruption to traffic and commercial activity and the price.  ETSI
         believes that the "fold and formed" process competes favorably in
         each of these areas with traditional replacement or repair methods. 
         In particular, the ability to install a "fold and formed" product
         with little or no excavation at prices typically at or below
         traditional open trench replacement method is a substantial
         competitive advantage.  Further, despite a small reduction in pipe
         diameter resulting from the installation of the "fold and formed"
         product against the walls of the original pipe, the smooth finished
         interior reduces friction and generally increases flow capacity.  

         ETSI believes that the trenchless pipeline reconstruction market is
         continuing to expand, with the entry of imitation and alternative
         products.  ETSI believes that its trenchless technology products and
         services are cost-competitive.  

         ETSW's competition comes from many smaller and narrowly focused
         companies in the Richmond and Northern Virginia areas. ETSW's major
         competitor in the trenchless sewer and water main rehabilitation
         business is Insituform, Inc., which is a cured-in-place technology. 
         ETSW believes that the "fold and formed" technology is superior and
         that it can underbid Insituform on projects and still provide
         adequate margins.  However, Insituform has been completing projects
         for municipalities for over a decade, and ETSW must first prove its
         proficiency in trenchless technology to municipalities through
         successful completion of small contracts before it will be chosen on
         larger programs. 

         ETSL's competitors in Florida include many small open-cut firms, as
         well as Insituform, using cured-in-place technology, and Madson-
         Barr, using "fold and formed" technology.  

         Current Projects
         ----------------

         As of June 26, 1998, ETSW had 27 major projects in progress,
         primarily for municipalities, such projects aggregating
         approximately $15 million.  Most of the projects will be completed
         on or before December 31, 1998.

<PAGE>
         As of June 26, 1998, ETSL had 17 major projects in progress,
         primarily for municipalities, such projects aggregating
         approximately $1.2 million.  Most of these projects will be
         completed on or before August 1998.  

         See "Services and Products" above.  

         Supervision and Regulation 
         --------------------------

         ETSI's infrastructure 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 Virginia Department of Health or Department of
         Public Works for sewer, septic and water systems.  Comparable state
         agencies regulate ETSL's activities in Florida.  ETSI does not
         anticipate any material impediments in the use of the "fold and
         formed" process arising from existing or future regulations or
         requirements, including those regulating discharges of materials
         into the environment. 

         Employees
         ---------

         As of March 31, 1998, ETSI, ETSW and ETSL employed 5, 130 and 14
         full-time personnel, respectively.  

Item 2.  Properties.
- ------   ----------

         During a portion of fiscal 1998, ETSI occupied approximately 45,000
         square feet of office and laboratory space in a modern commercial
         building in Roanoke, Virginia, under lease agreements with 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, former President and Chairman of the Board of
         ETSI, and Roberta Greiner, widow of Gary P. Greiner, a former
         officer and director of ETSI, are partners.  In connection with
         ETSI's sale of ETS, the ETS lease was assigned, effective February
         1, 1998, to ETS Acquisition, Inc, a Virginia corporation owned by
         John D. McKenna, Arthur B. Nunn III and John C. Mycock, former
         executive officers and directors of ETSI.  ETSI believes that the
         leases with PDJ Associates were on terms as favorable as those which
         would have been available from non-affiliated parties.  In
         connection with the sale of ETSAS described below, the ETSAS lease
         was assigned, effective October 31, 1997, to Q Enterprises, Inc., a
         Virginia corporation which was owned by James B. Quarles.  Mr.
         Quarles , who  subsequently became  President and a director of ETSI
         in January 1998,  sold his interest in Q Enterprises, Inc. on
         February 16, 1998.  Lease payments made by ETSI to PDJ Associates in
         fiscal 1998 totaled $164,000.

         Effective in 1994, ETSW entered into a lease of its premises which
         are owned by the Estate of Stamie E. Lyttle, of which Coleman S.
         Lyttle, a director of ETSI is executor,  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.  Rent expense under this
         lease was approximately $105,000 for fiscal 1998.  ETSI believes
         that the lease is on terms as favorable as those which would be
         available from non-affiliated third parties.  
<PAGE>
Item 3.  Legal Proceedings.
- ------   -----------------

         A lawsuit was served on ETSAS on or about March 18, 1998 and filed
         in the Circuit Court for Chesterfield County under the caption,
         Steven R. Pond v. ETS Analytical Services, Inc., Case No. 
         -----------------------------------------------
         041CL98000254-00 (Circuit Court for Chesterfield County).  In this
         lawsuit, Steven R. Pond ("Pond"), a former employee of ETSAS and the
         owner of premises leased to ETSAS, has asserted that ETSAS has
         breached its obligations under the lease by failing to make certain
         monthly payments, including late fees and interest, as well as by
         causing or permitting "physical damages and waste upon the
         premises."  Pond is seeking judgment against ETSAS "in the sum of
         $129,189.85 for accelerated rent, together with accrued late fees in
         the amount of $4,579.79; compensatory damages in the amount of
         $1,000.00, plus the costs of remediation and all damages, costs,
         liability or expense arising from or related to environmental
         contamination or environmental degradation of the premises;
         prejudgment interest at the rate of 1.00%; together with the costs
         of this action and award of attorney's fees and costs."  On April 8,
         1996, ETSAS filed a Special Plea, Grounds of Defense, and
         Counterclaim, in which ETSAS asserted that it is entitled to a
         set-off of any monies allegedly due and owing under the lease by
         virtue of Pond's indebtedness to ETSAS, in the amount of
         approximately $60,000, under a promissory note.  ETSAS intends to
         defend the lawsuit vigorously.  The case currently is scheduled to
         be set for trial at the Court's upcoming docket call on July 18,
         1998, at which time it is anticipated a hearing date also will be
         set for ETSAS' Special Plea.  It is not possible at this stage,
         however, to determine the outcome in the case or an estimate of the
         range of any potential loss.

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

      The purpose of this Corporation is to transact any or all lawful

           (b)   The Board of Directors of the Corporation (the "Board of
Directors") may, by amending these Articles of Incorporation (the "Articles")
by filing Articles of Amendment with the Virginia State Corporation
Commission, fix in whole or in part the preferences, limitations and rights,

of any shares of that class, or (ii) one or more series within a class,
before the issuance of any shares within that series.

           (c)   The preferred stock (including any shares of preferred
stock restored to the status of authorized but unissued preferred stock
undesignated as to series pursuant to this Article III(c)) may be divided
into one or more series and issued from time to time with such preferences,
privileges, limitations, and relative rights as shall be fixed and determined
by the Board of Directors.  Without limiting the generality of the foregoing,
the Board of Directors is expressly authorized to the fullest extent
permitted from time to time by law to fix:

                 (i)   the distinctive serial designations and the division
of shares of preferred stock into one or more series and the number of shares
of a particular series, which may be increased or decreased (but not below
the number of shares thereof then outstanding);
<PAGE>
                 (ii)  the rate or amount (or the method of determining the
rate or amount) and times at which, the form in which, and the preferences
and conditions under which, dividends shall be payable on shares of a
particular series, the status of such dividends as cumulative, partially
cumulative, or noncumulative, the date or dates from which dividends, if
cumulative, shall accumulate, and the status of such series as participating
or nonparticipating with shares of other classes or series;

                 (iii) the price or prices at which, the consideration for
which, the period or periods within which and the terms and conditions, if
any, upon which the shares of a particular series may be redeemed, in whole
or in part, at the option of the Corporation or otherwise;

                 (iv)  the amount or amounts and rights and preferences, if
any, to which the holders of shares of a particular series are entitled or
shall have upon any involuntary or voluntary liquidation, dissolution or
winding up of the Corporation;

                 (v)   the rights and preferences over or otherwise in
relation to any other class or series (including other series of preferred
stock), as to the right to receive dividends and/or the right to receive
payments out of the net assets of the Corporation upon any involuntary or
voluntary liquidation, dissolution or winding up of the Corporation;

                 (vi)  the right, if any, of the holders of a particular
series, the Corporation or another person to convert or cause conversion of
shares of such series into shares of other classes or series or into other
securities, cash, indebtedness or other property, or to exchange or cause
exchange of such shares for shares of other classes or series or other
securities, cash, indebtedness or other property, and the terms and
conditions, if any, including the price or prices or the rate or rates of
conversion and exchange, and the terms and conditions or adjustments, if any,
at which such conversion or exchange may be made or caused;

                 (vii) the obligation, if any, of the Corporation to redeem,
purchase or otherwise acquire, in whole or in part, shares of a particular
series for a sinking fund or otherwise, the terms and conditions thereof, if
any, including the price or prices and the nature of the consideration
payable for such shares so redeemed, purchased or otherwise acquired;

                 (viii) the voting rights, if any, including special,
conditional or limited voting rights, of the shares of a particular series in
addition to those required by law, including the number of votes per share
and any requirement for the approval by the holders of shares of all series
of preferred stock, or of the shares of one or more series thereof, or of
both, in an amount greater than a majority up to such amount as is in
accordance with applicable law or these Articles, as a condition to specified
corporate action or amendments to the Articles; and

                 (ix)  any other preferences, limitations and relative
rights which may be so determined by resolution or resolutions of the Board
of Directors.  Shares of preferred stock shall rank prior or superior to the
common stock in respect of the right to receive dividends and/or the right to
receive payments out of the net assets of the Corporation upon any
involuntary or voluntary liquidation, dissolution or winding up of the
Corporation.  All shares of preferred stock redeemed, purchased or otherwise
acquired by the Corporation (including shares surrendered for conversion or
exchange) shall be canceled and thereupon restored to the status of
authorized but unissued shares of preferred stock undesignated as to series.
<PAGE>
           (d)   The holders of common stock, to the exclusion of any other
class of stock of the Corporation, have sole power to vote for the election
of directors except as (i) otherwise expressly provided in the serial
designation of any series of preferred stock, (ii) otherwise expressly
provided in these Articles and (iii) otherwise expressly provided by the then
existing laws of the Commonwealth of Virginia.  The holders of common stock
will have one vote for each share of common stock held by them.

           (e)   No holder of shares of stock of any class of the
Corporation will have any preemptive or preferential right of subscription to
any shares of any class of stock of the Corporation, whether now or hereafter
authorized, or to any obligations of the Corporation convertible into stock
of the Corporation, issued or sold, nor any right of subscription to any
thereof.

          ARTICLE IV - INDEMNIFICATION OF DIRECTORS AND OFFICERS
          ------------------------------------------------------

      A.   Each Director and Officer who is or was a party to any proceeding
(including a proceeding by or in the right of the Corporation) shall be
indemnified by the Corporation against any liability imposed upon or asserted
against him (including amounts paid in settlement) arising out of conduct in
his official capacity with the Corporation or otherwise by reason of the fact
that he is or was such a Director or Officer or is or was serving at the
request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise, except there shall be no indemnification in relation to
matters as to which he shall have been finally adjudged to be liable by
reason of having been guilty of (i) willful misconduct or (ii) a knowing
violation of criminal law in the performance of his duty as such Director or
Officer.

      B.   In addition to the indemnification provided under Section A, to
the full extent permitted by the Virginia Stock Corporation Act and any other
applicable law, as they exist on the date hereof or may hereafter be amended,
the Corporation shall indemnify a Director or Officer of the Corporation who
is or was a party to any proceeding (including a proceeding by or in the
right of the Corporation) by reason of the fact that he is or was such a
Director or Officer or is or was serving at the request of the Corporation as
a director, officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise.

      C.   The Corporation is empowered to contract in advance to indemnify
any Director or Officer to the extent indemnification is granted under
Sections A and B.  The Board of Directors is also empowered to cause the
Corporation to indemnify or contract in advance to indemnify any other person
not covered by Sections A and B who was or is a party to any proceeding, by
reason of the fact that he is or was an employee or agent of the Corporation,
or is or was serving at the request of the Corporation as a director,
officer, employee or agent of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise to the same extent
as if such person were specified as one to whom indemnification is granted
under Sections A and B. 

      D.   The Corporation may advance, pay for and/or reimburse the
reasonable expenses incurred by an Officer or Director who is a party to any
proceeding in advance of the final disposition thereof if (i) the Officer or
Director furnishes the Corporation a written statement of his good faith
belief that he has met the standard of conduct described in Sections A and/or
<PAGE>
B above, (ii) the Officer or Director furnishes the corporation a written
undertaking, executed personally or on his behalf, to repay the advance if it
is ultimately determined that he did not meet the standard of conduct, and
(iii) a determination is made that the facts then known to those making the
determination would not preclude indemnification under this Article.  The
 undertaking required by clause (ii) above shall be an unlimited general
obligation of the Officer or Director but need not be secured and may be
accepted without reference to financial ability to make repayment.

      E.   All determinations as to indemnification and advances of expenses
(including contracts with respect thereto) shall be made by a majority vote
of a quorum of disinterested Directors.  In the event a quorum of
disinterested Directors cannot be obtained to make any determination as to
indemnification and advancement of expenses with respect to any claim for
indemnification made pursuant to this Article, such determinations shall be
made by special legal counsel agreed upon by the Board of Directors and the
proposed indemnitee.  If the Board of Directors and the proposed indemnitee
are unable to agree upon such special legal counsel, the Board of Directors
and the proposed indemnitee each shall select a nominee, and the nominees
shall select such special legal counsel.

      F.   The foregoing provisions are intended to provide indemnification
with respect to those monetary damages for which the Virginia Stock
Corporation Act permits the limitation or elimination of liability. In
addition, to the full extent that the Virginia Stock Corporation Act, as it
exists on the date hereof or may hereafter be amended, permits the limitation
or elimination of the liability of directors, a Director of the Corporation
shall not be liable to the Corporation or its stockholders for monetary
damages arising out of a single transaction, occurrence or course of conduct
in excess of the amount of cash consideration received by the Directors from
the Corporation for services as a Director during the twelve months
immediately preceding the act or omission for which liability was imposed.

      G.   The Corporation may purchase and maintain insurance to indemnify
it against the whole or any portion of the liability assumed by it in
accordance with this Article and may also procure insurance, in such amounts
as the Board of Directors may determine, on behalf of any person who is or
was a Director, Officer, employee or agent of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise, against any liability asserted against or
incurred by such person in any such capacity or arising from his status as
such, whether or not the Corporation would have power to indemnify him
against such liability under the provision of this Article.

      H.   The provisions of this Article shall be applicable to all
actions, claims, suits or proceedings commenced after the adoption hereof,
whether arising from any action taken or failure to act before or after such
adoption.  No amendment, modification or repeal of this Article shall
diminish the rights provided hereby or diminish the right to indemnification
with respect to any claim, issue or matter in any then pending or subsequent
proceeding that is based in any material respect on any alleged action or
failure to act prior to such amendment, modification or repeal.

      I.   Except to the extent inconsistent with this Article, terms used
herein shall have the same meanings assigned them in the Indemnification
Article of the Virginia Stock Corporation Act as now in effect or hereafter
amended.  Without limitation, it is expressly understood that reference
herein to Directors, Officers, employees or agents shall include former
Directors, Officers, employees and agents and their respective heirs,
executors and administrators.<PAGE>

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

      The principal office of the corporation shall be located in Richmond,
Virginia.  The corporation may have such other offices, either within or

shall be held in the month of July in each year at such time, day and place
as the Board of Directors may designate, for the purpose of electing
Directors and for the transaction of such other business as may come before
the meeting.  If the election of Directors shall not be held on the date
designated for any annual meeting of the shareholders, or any adjournment
thereof, the Board of Directors shall cause the election to be held at a
special meeting of the shareholders as soon thereafter as conveniently may
be.

      SECTION 2.  Special Meetings.  Special meetings of the shareholders,
                  ----------------
for any purpose or purposes, unless otherwise prescribed by statute, may be
called by the President, the Board of Directors, and by holders of not less
than twenty percent of all the outstanding shares of the corporation entitled
to vote at the meeting.

      SECTION 3.  Place of Meeting.  The Board of Directors may designate any
                  ----------------
place, either within or without the state of incorporation unless otherwise
prescribed by statute, as the place of meeting for any annual meeting or for
any special meeting called by the Board of Directors.  A waiver of notice
signed by all shareholders entitled to vote at a meeting may designate any
place, either within or without the state of incorporation, unless otherwise
prescribed by statute, as the place for the holding of such meeting.  If no
designation is made, or if a special meeting be otherwise called, the place
of meeting shall be the principal office of the corporation.

      SECTION 4.  Notice of Meeting.  Written or printed notice stating the
                  -----------------
place, day and hour of the meeting and in case of a special meeting, the
purpose or purposes for which the meeting is called, shall be delivered not
less than ten nor more than sixty days before the date of the meeting, either
personally or by mail, by or at the direction of the President, or the
<PAGE>
Secretary, or the officer or persons calling the meeting, to each shareholder
of record entitled to vote at such meeting. If mailed, such notice shall be
deemed to be delivered when deposited in the United States mail, addressed to
the shareholder at his address as it appears on the stock transfer books of
the corporation, with postage thereon prepaid.

      Notice of a shareholder's meeting to act on an amendment of the
articles of incorporation or on a reduction of stated capital or on a plan of
merger or consolidation shall be given, in the manner provided above, not
less than twenty-five nor more than sixty days before the date of the
meeting.  Any such notice shall be accompanied by a copy of the proposed
amendment or plan of reduction or merger or consolidation.

      SECTION 5.  Closing of Transfer Books or Fixing of Record Date.  For 
                  --------------------------------------------------
the purpose of determining shareholders entitled to notice of or to vote at
any meeting of shareholders or any adjournment thereof, or shareholders
entitled to receive payment of any dividend, or in order to make a
determination of shareholders for any other proper purpose, the Board of
Directors of the corporation may provide that the stock transfer books shall
be closed for a stated period but not to exceed, in any case, seventy days. 
If the stock transfer books shall be closed for the purpose of determining
shareholders entitled to notice of or to vote at a meeting of shareholders,
such books shall be closed for at least ten days immediately preceding such
meeting.  In lieu of closing the stock transfer books, the Board of Directors
may fix in advance a date as the record date for any such determination of
shareholders, such date in any case to be not more than seventy days and, in
case of a meeting of shareholders, not less than ten days prior to the date
on which the particular action, requiring such determination of shareholders,
is to be taken.  If the stock transfer books are not closed and no record
date is fixed for the determination of shareholders entitled to notice of or
to vote at a meeting of shareholders, or shareholders entitled to receive
payment of a dividend, the date on which the notice is given or the date on
which the resolution of the Board of Directors declaring such dividend is
adopted, as the case may be, shall be the record date for such determination
of shareholders.  When a determination of shareholders entitled to vote at
any meeting of shareholders has been made as provided in this section, such
determination shall apply to any adjournment thereof.

      SECTION 6.  Quorum.  A majority of the outstanding shares of the
                  ------
corporation entitled to vote, represented in person or by proxy, shall
constitute a quorum at a meeting of shareholders.  If less than a majority of
the outstanding shares are represented at a meeting, a majority of the shares
so represented may adjourn the meeting from time to time without further
notice.  At such adjourned meeting at which a quorum shall be present or
represented, any business may be transacted which might have been transacted
at the meeting as originally notified.  The shareholders present at a duly
organized meeting may continue to transact business until adjournment,
notwithstanding the withdrawal of enough shareholders to leave less than a
quorum.

      SECTION 7.  Proxies.  At all meetings of shareholders, a shareholder
                  -------
may vote by proxy executed in writing by the shareholder or by his duly
authorized attorney in fact.  Such proxy shall be filed with the secretary of
the corporation before or at the time of the meeting.
<PAGE>
      SECTION 8.  Chairman and Secretary.  The Chairman and Secretary of the
                  ----------------------

Chairman shall preside at such meetings, and the Secretary shall be
responsible for keeping minutes thereof in one or more books provided for
that purpose.

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

taken unless his or her dissent shall be entered in the minutes of the

the meeting.  Such right to dissent shall not apply to a Director who voted
in favor of such action.

meeting can hear each other, and participation by such means shall constitute
presence in person at such meeting.

                   -----------------------
at a meeting of Directors, or any action which may be taken at a meeting of

judgment the best interests of the corporation would be served thereby, but
such removal shall be without prejudice to the recovery of damages for breach

principal and interest shall be paid in full, provided, however, that Payee

principal and interest owing and demand payment in full upon sixty (60) days

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

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

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 dated March 17, 1997
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 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.
<PAGE>
           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 any Guarantor and Payee, or if there
occurs any other event of 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) 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
<PAGE>
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.

           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 right 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.
<PAGE>
           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.

           Applicable Law and Jurisdiction.  This Note shall be governed by
and interpreted according to the laws of the Commonwealth of Virginia,

      or claim in favor of any third party, and no financing statement is on
      file in any public office covering any of the Collateral, except in

      Owner, enforceable in accordance with its terms.

           (c)   All information that Owner has furnished or in the future

      including, without limitation, all financial statements and all
      information concerning the condition, quality, or value of the
      Collateral, is and will be correct and complete in all material
      respects.

           (d)   Owner is a corporation, and is organized and validly
      existing in good standing under the laws of the Commonwealth of
      Virginia; Owner has full power and authority to enter into and perform

<PAGE>
      4.   Agreements of Owner.  Owner agrees that:

           (a)   Except for the Permitted Liens and purchase money security
      interest liens, Owner shall not cause or permit any lien, security
      interest, or encumbrance to be placed on any Collateral, except in
      favor of Secured Party, and Owner shall not sell, assign, or transfer
      any Collateral or permit any Collateral to be transferred by operation
      of law, except that, as long as there shall not have occurred an event
      of default as defined in this Agreement, Owner may sell inventory in
      the ordinary course of Owner's business.  A sale in the ordinary course
      of business does not include a transfer in partial or complete
      satisfaction of a debt.

           (b)   Owner shall maintain all records concerning the Collateral
      at Owner's address appearing on the first page of this Agreement and
      will keep all tangible Collateral at the present location or locations
      of the Collateral.

           (c)   Owner shall furnish Secured Party with all information
      regarding the Collateral that Secured Party shall from time to time 
      reasonably request (including without limitation, the names and
      addresses of Owner's account debtors and the amount owed by each) and
      shall allow Secured Party at any reasonable time to inspect the
      Collateral and Owner's records regarding the Collateral.

           (d)   Owner shall sign, file, record, or obtain from third
      persons, all financing statements, subordination agreements, and other
      documents, and take all other action, that Secured Party may consider
      necessary or appropriate to perfect, to continue perfection of, or to
      maintain first priority of, Secured Party's security interest in the
      Collateral subject only to the Permitted Liens and purchase money
      security interest liens, and Owner shall place upon the Collateral
      and/or documents evidencing the Collateral any notice of Secured
      Party's security interest that Secured Party may from time to time
      require.

           (e)   Secured Party may file a photocopy of this Agreement as a
      financing statement evidencing Secured Party's security interest in the
      Collateral.

           (f)   Owner shall immediately notify Secured Party in writing of
      any change in Owner's name, identity, or corporate structure, and of
      any change in the location of Owner's place of business and of the
      location of each additional place of business established by Owner.

           (g)   Owner shall indemnify Secured Party with respect to all 
      losses, damages, liabilities, and expenses (including reasonable
      attorney fees) incurred by Secured Party by reason of any failure of
      Owner to comply with any of Owner's obligations under this Agreement or
      by reason of any warranty or representation made by Owner to Secured
      Party in this Agreement being false in any material respect.

           (h)   Secured Party may from time to time contact Owner's account
      debtors for the purpose of verifying the existence, amount, and
      collectibility of, and other information regarding, any part of the
      Collateral at any time consisting of accounts, chattel paper,
      instruments, or general intangibles.
<PAGE>
           (i)   Owner shall maintain all tangible Collateral in good
      condition and repair, ordinary wear and tear excepted, and maintain
      fire and extended coverage insurance covering all tangible Collateral
      in the amounts and against the risks that is customarily maintained by
      similar businesses.  Each insurance policy shall provide that its
      proceeds shall be payable to Secured Party to the extent of Secured
      Party's interest in the Collateral and that the policy shall not be
      canceled, and the coverage shall not be reduced, without at least 10
      days' prior written notice by the insurer to Secured Party. Owner shall
      provide Secured Party with evidence of that insurance coverage.  Owner
      agrees that Secured Party may act as agent for Owner in obtaining,
      adjusting, and settling that insurance and endorsing any draft
      evidencing proceeds of it.

           (j)   Owner shall pay, before they become delinquent, all taxes
      and assessments upon the Collateral or for its use or operation, and
      pay and perform when due all indebtedness and obligations under all
      leases, land contracts, or other agreements under which Owner has
      possession of any real property upon which any of the Collateral shall
      at any time be located and under any mortgage or mortgages at any time
      covering that real property.

      5.   Secured Party's Right to Perform.  If Owner fails to perform any
obligation of Owner under this Agreement, Secured Party may, without giving
notice to or obtaining the consent of Owner, perform that obligation on
behalf of Owner.  (This may include, for example, obtaining insurance
coverage for Collateral, paying off liens on Collateral, or cleaning up
environmental contamination of, or caused by, Collateral.) Owner will
reimburse Secured Party on demand for any expense that Secured Party incurs
in performing the obligation and will pay to Secured Party interest on each
expense, from the date the expense was incurred by Secured Party, at an
annual rate equal to twelve percent (12%) per annum.  Secured Party is not
required to perform an obligation that Owner has failed to perform.  If
Secured Party does so, that will not be a waiver of Secured Party's right to
declare the Indebtedness immediately due and payable by reason of Owner's
failure to perform.

      6.   Events of Default and Acceleration.  Any part or all of the
Indebtedness shall, at the option of Secured Party, become immediately due
and payable without notice or demand upon the occurrence of any event of
default under the Promissory Note executed by Owner and dated March 17, 1997.

      7.   Secured Party's Rights and Remedies.  Secured Party shall have
all rights and remedies of a secured party under applicable laws.  Without
limiting these rights and remedies:

           (a)   Upon the occurrence of an event of default, as defined in
      Paragraph 6 above, (i) without notice or demand to Owner, Secured Party
      shall be entitled to notify Owner's account debtors and obligors to
      make all payments directly to Secured Party, and Secured Party shall
      have the right to take all actions that Secured Party considers
      necessary or desirable to collect upon the Collateral, including,
      without limitation, prosecuting actions against, or settling or
      compromising disputes and claims with, Owner's account debtors and
      obligors, (ii) without notice or demand to Owner, Secured Party may
      receive, open, dispose of, and notify the postal authorities to change
      the address of, mail directed to Owner, and (iii) upon demand by
<PAGE>
      Secured Party, Owner shall immediately deliver to Secured Party, at the
      place that Secured Party shall designate, all proceeds of the
      Collateral and all books, records, agreements, leases, documents, and
      instruments evidencing or relating to the Collateral.

      that Secured Party shall designate, and Secured Party may dispose of
      the Collateral in any commercially reasonable manner.  Any notification

           (d)   The proceeds of any collection or disposition of Collateral
      shall be applied first to Secured Party's reasonable attorney fees and
      expenses, as provided in Paragraph 8 of this Agreement, and then to the
      Indebtedness, and Owner shall be liable for any deficiency remaining.

All rights and remedies of Secured Party shall be cumulative and may be
exercised from time to time.

      8.   Expenses.  Owner shall reimburse Secured Party on demand for all
reasonable attorney fees, legal expenses, and other expenses that Secured

person.  Secured Party may apply any proceeds of collection or disposition of
Collateral to Secured Party's reasonable attorney fees, legal expenses, and
other expenses.

      9.   Amendments and Waivers.  No provision of this Agreement may be
modified or waived except by a written agreement signed by Secured Party. 
Secured Party will continue to have all of its rights under this Agreement
even if it does not fully and promptly exercise them on all occasions.

default; extend or modify the time or manner of payment of the Indebtedness

release Collateral or other security for the Indebtedness; release any person
liable for any of the Indebtedness, including any borrower or Guarantor; or

Collateral or Owner's obligations under this Agreement.  Secured Party's
security interest in the Collateral and Owner's obligations under this
Agreement will not be released or impaired if Secured Party fails to obtain,
perfect, or secure priority of any other security for the Indebtedness that

to, Virginia law.

      12.  Binding Effect.  This Agreement shall be binding upon and inure
to the benefit of Owner and Secured Party and their respective successors,
and assigns.

      evidencing the Collateral any notice of Secured Party's security
      interest that Secured Party may from time to time require.

      Collateral.

      (f)  Owner shall immediately notify Secured Party in writing of any
      change in Owner's name, identity, or corporate structure, and of any
      change in the location of Owner's place of business and of the location
      of each additional place of business established by Owner.

      (g)  Owner shall indemnify Secured Party with respect to all losses,
      damages, liabilities, and reasonable expenses (including attorney fees)
      incurred by Secured Party by reason of any failure of Owner to comply

      instruments, or general intangibles.

      (i)  Owner shall maintain all tangible Collateral in good condition
      and repair, ordinary wear and tear excepted, and maintain fire and

      amounts and against the risks that is customarily maintained by similar
      businesses, or as Secured Party may reasonably request.  Each insurance
      policy shall provide that its proceeds shall be payable to Secured
      Party to the extent of Secured Party's interest in the Collateral and
<PAGE>
      that the policy shall not be canceled, and the coverage shall not be
      reduced, without at least 10 days' prior written notice by the insurer
      to Secured Party. Owner shall provide Secured Party with evidence of
      that insurance coverage. Owner agrees that Secured Party may act as

      (j)  Owner shall pay, before they become delinquent, all taxes and
      assessments upon the Collateral or for its use or operation, and pay
      and perform when due all indebtedness and obligations under all leases,
      land contracts, or other agreements under which Owner has possession of
      any real property upon which any of the Collateral shall at any time be
      located and under any mortgage or mortgages at any time covering that
      real property.

      5.   Secured Party's Right to Perform.  If Owner fails to perform any
obligation of Owner under this Agreement, Secured Party may, without giving
notice to or obtaining the consent of Owner, perform that obligation on
behalf of Owner. (This may include, for example, obtaining insurance coverage
for Collateral, paying off liens on Collateral, or cleaning up environmental
contamination of, or caused by, Collateral.) Owner will reimburse Secured
Party on demand for any expense that Secured Party incurs in performing the
obligation and will pay to Secured Party interest on each expense, from the
date the expense was incurred by Secured Party, at an annual rate equal to
twelve percent (12%) per annum.  Secured Party is not required to perform an
obligation that Owner has failed to perform.  If Secured Party does so, that
will not be a waiver of Secured Party's right to declare the Indebtedness
immediately due and payable by reason of Owner's failure to perform.

      6.   Events of Default and Acceleration.  Any part or all of the
Indebtedness shall, at the option of Secured Party, become immediately due

      shall be entitled to notify Owner's account debtors and obligors to
      make all payments directly to Secured Party, and Secured Party shall
      have the right to take all actions that Secured Party considers
      necessary or desirable to collect upon the Collateral, including,

      compromising disputes and claims with, Owner's account debtors and
      obligors, (ii) without notice or demand to Owner, Secured Party may
      receive, open, dispose of, and notify the postal authorities to change

      Secured Party shall have the right (but no obligation) to continue or
      complete the manufacturing, or processing of, or other operations in
      connection with, any part of the Collateral, and, for that purpose, to
      enter and remain upon or in any land or buildings that are possessed by
      Owner or that Owner has the right to possess. Owner will reimburse
      Secured Party on demand for any reasonable expense that Secured Party
      incurs in connection with those activities and will pay to Secured
      Party interest on each expense, from the date the expense was incurred
      by Secured Party, at the rate specified in Paragraph 5 of this
      Agreement.

      (d)  The proceeds of any collection or disposition of Collateral shall
      be applied first to Secured Party's reasonable attorney fees and
      expenses, as provided in Paragraph 8 of this Agreement, and then to the

modified or waived except by a written agreement signed by Secured Party.

Collateral or Owner's obligations under this Agreement.  Secured Party's
security interest in the Collateral and Owner's obligations under this
Agreement will not be released or impaired if Secured Party fails to obtain,

other security before exercising its rights under this Agreement.

           and will not violate Owner's articles of incorporation or bylaws.

           (e)   None of the Collateral is, and Owner will not permit any of
           the Collateral to be, contaminated in excess of legal levels or
           the source of unlawful contamination of any other property, by
           any substance that is now or in the future regulated by or
           subject to any past, present, or future federal, state, local, or
           foreign law, ordinance, rule, regulation, or order that regulates

           substances. Owner will store, operate and maintain the Collateral
           in compliance with all of those laws and regulations in all
           material respects.

           security interest, or encumbrance to be placed on any Collateral,
<PAGE>
           except in favor of Secured Party. Owner shall not sell, assign,
           or transfer any Collateral or permit any Collateral to be
           transferred by operation of law, except that, as long as there
           shall not have occurred an event of default as defined in this
           Agreement, Owner may sell inventory in the ordinary course of
           Owner's business. A sale in the ordinary course of business does
           not include a transfer in partial or complete satisfaction of a
           debt.

           (b)   Owner shall maintain all records concerning the Collateral
           at Owner's address appearing on the first page of this Agreement
           and will keep all tangible Collateral at the present location or
           locations of the Collateral.

           (c)   Owner shall furnish Secured Party with all information
           regarding the Collateral that Secured Party shall from time to
           time reasonably request (including without limitation, the names
           and addresses of Owner's account debtors and the amount owed by
           each) and shall allow Secured Party at any reasonable time to
           inspect the Collateral and Owner's records regarding the
           Collateral.

           (d)   Owner shall sign, file, record, or obtain from third
           persons, all financing statements, subordination agreements, and
           other documents, and take all other action, that Secured Party
           may consider necessary or appropriate to perfect, to continue
           perfection of, or to maintain first priority of, Secured Party's
           security interest in the Collateral subject to the Permitted
           Liens and purchase money security interest liens, and Owner shall
           place upon the Collateral and/or documents evidencing the
           Collateral any notice of Secured Party's security interest that
           Secured Party may from time to time require.

           (e)   Secured Party may file a photocopy of this Agreement as a
           financing statement evidencing Secured Party's security interest
           in the Collateral.

           (f)   Owner shall immediately notify Secured Party in writing of
           any change in Owner's name, identity, or corporate structure, and
           of any change in the location of Owner's place of business and of
           the location of each additional place of business established by
           Owner.

           (g)   Owner shall indemnify Secured Party with respect to all
           losses, damages, liabilities, and reasonable expenses (including
           attorney fees) incurred by Secured Party by reason of any failure
           of Owner to comply with any of Owner's obligations under this
           Agreement or by reason of any warranty or representation made by
           Owner to Secured Party in this Agreement being false in any
           material respect.

           (h)   Secured Party may from time to time contact Owner's account
           debtors for the purpose of verifying the existence, amount, and
           collectibility of, and other information regarding, any part of
           the Collateral at any time consisting of accounts, chattel paper,
           instruments, or general intangibles.

           (i)   Owner shall maintain all tangible Collateral in good
           condition repair, ordinary wear and tear excepted, and maintain
<PAGE>
           fire and extended coverage insurance covering all tangible
           Collateral in the amounts and against the risks that is
           customarily maintained by similar businesses, or as Secured Party
           may reasonably request.  Each insurance policy shall provide that
           its proceeds shall be payable to Secured Party to the extent of
           Secured Party's interest in the Collateral and that the policy
           shall not be canceled, and the coverage shall not be reduced,
           without at least 10 days' prior written notice by the insurer to
           Secured Party. Owner shall provide Secured Party with evidence of
           that insurance coverage. Owner agrees that Secured Party may act
           as agent for Owner in obtaining, adjusting, and settling that
           insurance and endorsing any draft evidencing proceeds of it.

           (j)   Owner shall pay, before they become delinquent, all taxes
           and assessments upon the Collateral or for its use or operation,
           and pay and perform when due all indebtedness and obligations
           under all leases, land contracts, or other agreements under which
           Owner has possession of any real property upon which any of the
           Collateral shall at any time be located and under any mortgage or
           mortgages at any time covering that real property.

      5.   Secured Party's Right to Perform. If Owner fails to perform any
obligation of Owner under this Agreement, Secured Party may, without giving
notice to or obtaining the consent of Owner, perform that obligation on
behalf of Owner. (This may include, for example, obtaining insurance coverage
for Collateral, paying off liens on Collateral, or cleaning up environmental
contamination of, or caused by, Collateral.) Owner will reimburse Secured
Party on demand for any expense that Secured Party incurs in performing the
obligation and will pay to Secured Party interest on each expense, from the
date the expense was incurred by Secured Party, at an annual rate equal to
twelve percent (12%) per annum. Secured Party is not required to perform an
obligation that Owner has failed to perform. If Secured Party does so, that
will not be a waiver of Secured Party's right to declare the Indebtedness
immediately due and payable by reason of Owner's failure to perform.

      6.   Events of Default and Acceleration. Any part or all of the
Indebtedness shall, at the option of Secured Party, become immediately due
and payable without notice or demand upon the occurrence of any event of
default under the Promissory Note dated March 17, 1997, made by ETS
International, Inc.

      7.   Secured Party's Rights and Remedies. Secured Party shall have all
rights and remedies of a secured party under applicable laws. Without
limiting these rights and remedies:

           (a)   Upon the occurrence of an event of default, as defined in
           Paragraph 6 above, (i) without notice or demand to Owner, Secured
           Party shall be entitled to notify Owner's account debtors and
           obligors to make all payments directly to Secured Party, and
           Secured Party shall have the right to take all actions that
           Secured Party considers necessary or desirable to collect upon
           the Collateral, including, without limitation, prosecuting
           actions against, or settling or compromising disputes and claims
           with, Owner's account debtors and obligors, (ii) without notice
           or demand to Owner, Secured Party may receive, open, dispose of,
           and notify the postal authorities to change the address of, mail
           directed to Owner, and (iii) upon demand by Secured Party, Owner
<PAGE>
           shall immediately deliver to Secured Party, at the place that
           Secured Party shall designate, all proceeds of the Collateral and
           all books, records, agreements, leases, documents, and
           instruments evidencing or relating to the Collateral.

           (b)   If all or any part of the Indebtedness is not paid at
           maturity, Owner, upon demand by Secured Party, shall deliver the
           Collateral and proceeds of Collateral to Secured Party at the
           place that Secured Party shall designate, and Secured Party may
           dispose of the Collateral in any commercially reasonable manner.
           Any notification required to be given by Secured Party to Owner
           regarding any sale or other disposition of Collateral shall be
           considered reasonable if mailed at least 10 days before the sale
           or other disposition.

           (c)   If all or any part of the Indebtedness is not paid at
           maturity, Secured Party shall have the right (but no obligation)
           to continue or complete the manufacturing, or processing of, or
           other operations in connection with, any part of the Collateral,
           and, for that purpose, to enter and remain upon or in any land or
           buildings that are possessed by Owner or that Owner has the right
           to possess. Owner will reimburse Secured Party on demand for any
           reasonable expense that Secured Party incurs in connection with
           those activities and will pay to Secured Party interest on each
           expense, from the date the expense was incurred by Secured Party,
           at the rate specified in Paragraph 5 of this Agreement.

           (d)   The proceeds of any collection or disposition of Collateral
           shall be applied first to Secured Party's reasonable attorney
           fees and expenses, as provided in Paragraph 8 of this Agreement,
           and then to the Indebtedness, and Owner shall be liable for any
           deficiency remaining.

All rights and remedies of Secured Party shall be cumulative and may be
exercised from time to time.

      8.   Expenses. Owner shall reimburse Secured Party on demand for all
reasonable attorney fees, legal expenses, and other expenses that Secured
Party incurs in protecting and enforcing its rights under this Agreement.
This includes fees and expenses incurred in trying to take possession of
Collateral from Owner, a trustee or receiver in bankruptcy or any other
person. Secured Party may apply any proceeds of collection or disposition of
Collateral to Secured Party's reasonable attorney fees, legal expenses, and
other expenses.

      9.   Amendments and Waivers. No provision of this Agreement may be
modified or waived except by a written agreement signed by Secured Party.
Secured Party will continue to have all of its rights under this Agreement
even if it does not fully and promptly exercise them on all occasions.
Secured Party may, at its option, waive any default, defer an action on any
default; extend or modify the time or manner of payment of the Indebtedness
or waive or modify any term or condition relating to the Indebtedness;
release Collateral or other security for the Indebtedness; release any person
liable for any of the Indebtedness, including any borrower or Guarantor; or
make advances or other extensions of credit secured by this Agreement; all
without giving Owner notice or obtaining Owner's consent. Any such action by
Secured Party will not release or impair its security interest in the
Collateral or Owner's obligations under this Agreement. Secured Party's
security interest in the Collateral and Owner's obligations under this
<PAGE>
Agreement will not be released or impaired if Secured Party fails to obtain,
perfect, or secure priority of any other security for the Indebtedness that
is agreed to be given, or is given, by anyone else. Secured Party is not
required to sue upon or otherwise enforce payment of the Indebtedness or any
other security before exercising its rights under this Agreement.

      10.  Notices. Any notice to Owner or to Secured Party shall be
considered to be given if and when mailed, with postage prepaid, to the
respective address of Owner or Secured Party appearing on the first page of
this Agreement, or if and when delivered personally.

      11.  Other. In this Agreement, "maturity" of any of the Indebtedness
means the time when that Indebtedness has become due and payable, for
whatever reason (including, for example, acceleration due to default or
bankruptcy). This Agreement will be governed by, and interpreted according
to, Virginia law.

      12.  Binding Effect. This Agreement shall be binding upon and inure to
the benefit of Owner and Secured Party and their respective successors, and
assigns.

           Owner and Secured Party have signed this Security Agreement as of
the date stated on the first page.

Contractor commences operations under this Agreement and shall continue in
force throughout the Term.

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

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 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.

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, tradenames, trademark,
certification mark or corporate name that includes any of the forgoing words;

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

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

ALLOY (Trademark) or ULTRALINER PVC ALLOY PIPELINER (Trademark) or ULTRALINER
PVC ALLOY PIPELINER SYSTEM (Trademark) is available for use as a service

      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.

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

other service and/or trademarks, tarde names, copyrights licenses hereunder
without the consent of the Licensor, or any other Confidential Material or

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.

      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.

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.

Agreement by the Licensor, the assignment, transfer, or conveyance shall be
completed without additional License fees or other costs being assessed to
the Contractor.

                             MESSAGE TO SHAREHOLDERS




Dear Shareholders:

         ETS International ("ETSI") had a very difficult fiscal 1998 and is
capital deficient. This was a result primarily of its investing heavily in an
attempt to commercialize the patented Limestone Emission Control ("LEC") system
on an international level and failing to raise additional funds with which to go
forward in a weak environmental marketplace. By mid-year, it was clear that the
environmental technology development strategy pursued by your Company was no
longer viable. The financial position has deteriorated to the point that ETSI
common stock was delisted from trading on the American Stock Exchange in March
1998 and the future continued operation of your Company is at risk. From a
financial perspective, fiscal year 1998, ended two months early on March 31,
produced $12,644,431 in revenues and a net loss of $4,807,351, or $0.31 per
share. The losses were attributable primarily to write-offs associated with
ETSI's environmental subsidiaries and, to a lesser extent, the impact of
weather-related delays on construction projects. The losses resulted in negative
working capital of $3,069,250, which placed your Company in default on its
borrowings. Further, it is possible that a contract to build three LEC units on
behalf of China Steel Corporation ("CSC") at its facility in Taiwan, was
under-priced and could have a very negative impact on ETSI going forward.

         I agreed to join your Company as President and Chief Executive Officer
on January 20, 1998. I subsequently became Chairman upon the resignation of John
McKenna on February 2, 1998. I accepted the challenges by way of a six-month
contract with the commitment to attempt to stabilize the financial condition of
ETSI, sell off unprofitable businesses and develop a strategy for the future,
intended to enhance shareholder value.
In that regard, the following steps have been taken:

          o         arrangements  were  successfully  made  for  your  Company's
                    common  stock to trade on the OTC  Bulletin  Board under the
                    symbol "ETSI";

          o         your  Company has adopted a newly  disciplined  and singular
                    focus on the installation and  rehabilitation  of subsurface
                    pipelines for the  transmission of water,  waste and natural
                    gas;

          o         all remaining  environmental  subsidiary  assets  (including
                    patents) and certain  liabilities  were transferred in March
                    1998 to a new  company,  formed  by John  McKenna  and other
                    former Company executives, for approximately $1,900,000 plus
                    fifty percent of any future  royalties  associated  with the
                    LEC. ETSI has as yet not been able to successfully  transfer
                    the contract  with CSC,  but entered into an agreement  with
                    another  company  formed by the former  executives to manage
                    the  CSC   Contract  and  assume   responsibility   for  any
                    liabilities associated with the CSC Contract.  Still, in the
                    event this new  company  defaults  on its  obligations,  CSC
                    could hold your Company liable.  Negotiations  are presently
                    underway  with CSC seeking  transfer of the CSC  Contract in
                    its entirety to the new  company.  There can be no assurance
                    that  these   negotiations   will  be   successful.   ETSI's
                    environmental  laboratory  subsidiary's  assets were sold in
                    October 1997 in exchange for a $1,000,000  promissory  note,
                    which is  secured  by the  buyer's  stock and the  purchased
                    equipment;

          o         in an effort to reduce future overhead  costs,  your Company
                    closed its Roanoke corporate headquarters office, terminated
                    certain corporate  executive  positions and consolidated its
                    operations in Richmond,  Virginia, where ETSI's construction
                    subsidiary is based;

          o         your   Company's   Richmond,   Virginia-based   construction
                    subsidiary sold its septic and plumbing services division in
                    April 1998 for  $700,000,  consisting  of cash, a promissory
                    note  and  the  assumption  of  certain   liabilities.   The
                    construction subsidiary has since been awarded the largest

                                        1

<PAGE>



                    contract  in its history for  approximately  $4,000,000  for
                    pipeline  work to be  performed  on  behalf  of the  City of
                    Petersburg,  Virginia.  In  addition,  Motorola  Corporation
                    awarded the  subsidiary a contract to perform  approximately
                    $1,000,000 of pipeline work, and the subsidiary's authorized
                    backlog was approximately $12,000,000 at May 31, 1998;

          o         your  Company's  debt  financing was  restructured  with its
                    primary lender with the annual  interest rate reduced to ten
                    percent,   and  attempts  to  obtain  new  debt  and  equity
                    financing  are  underway.  Management  is  negotiating  with
                    certain   promissory   note   holders  to  convert  debt  of
                    approximately  $4,000,000 to preferred stock and to obtain a
                    line of credit  from a bank.  Management's  success in these
                    regards will, to a large extent, depend upon whether ETSI is
                    able to  accomplish  the  transfer of the CSC  Contract to a
                    third party, of which there can be no assurance; and

         o        an independent Management Advisory Committee (the "MAC") was
                  created with retired Chief of Naval Operations, Admiral Elmo
                  R. Zumwalt, Jr., being the first to join and serve as its
                  Chairman. Other advisors slated to join the MAC (contingent
                  upon ETSI being re-capitalized as described above) include Mr.
                  Charles Bowsher, recently retired Controller General of the
                  United States General Accounting Office; and Mr. Charles
                  DiBona, recently retired President of the American Petroleum
                  Institute. Additional advisors will be recruited to join the
                  MAC and provide the seasoned guidance helpful in defining and
                  achieving your Company's goals.

         While there are no guarantees, management is working to stabilize and
expand ETSI's existing infrastructure-related operations in Virginia and further
expand operations to adjacent southeastern states. ETSI's small eighteen-month
old Florida subsidiary, which deploys trenchless technologies for pipeline
rehabilitation, continues to lose money and is being closely monitored. If
profitability is not achieved by the Florida subsidiary relatively soon, it may
be divested. Expansion via mergers with profitable companies performing
compatible operations throughout the United States and sharing the goal of
becoming a consolidated industry leader in the installation and rehabilitation
of subsurface pipelines for the transmission of water, waste and natural gas,
would be a natural progression for ETSI. These opportunities will be carefully
evaluated if they arise.

         I believe that a new name for your Company will better reflect its
focus on the delivery of infrastructure- related pipeline installation and
rehabilitation services and deployment of trenchless technologies. I urge you to
approve management's request to change your Company's name from ETSI to
"InfraCorps Inc."

         Management has considerable work ahead and success cannot be assured.
In the near term, we intend to focus attention on the further restructuring of
your Company's Board of Directors, attempting to strengthen the management team
with senior-level executives who possess construction industry experience, and
implementing cost reductions in ETSI's operations and corporate activities. In
addition, we will be pursuing strategic opportunities that would help stabilize
and strengthen your Company's core business as outlined in this report.

         I will keep you informed of our progress during this next fiscal year.
I am cautiously optimistic that we can secure a stable financial base for your
Company with the goals of increasing shareholder value and providing a platform
for future profitable growth. Your continued support and patience will be
greatly appreciated.

Sincerely,

                                 COMPANY PROFILE

         ETS International, Inc. ("ETSI"), a Virginia corporation formed in
1987, is a technology-based firm that historically has provided both
environmental and construction products and services. During the second half of
fiscal 1998, ETSI made a determination to focus on its construction lines of
business and to de-emphasize its environmental products and services.
Specifically, ETSI is directing its efforts to the development and growth of its
existing underground infrastructure products and services related to the
installation and rehabilitation of subsurface pipelines using trenchless
technologies. Trenchless technology involves the installation and rehabilitation
of underground pipelines with minimal surface disruption. Some of the methods
used are pipe relining, manhole construction and "pipe bursting."

         As part of its refocusing effort, ETSI undertook a major management
reorganization, sold substantially all of the assets of its two environmental
related subsidiaries, relocated its corporate headquarters to Richmond,
Virginia, where ETSI's construction subsidiary is based, changed the names of
certain of its subsidiaries to reflect ETSI's emphasis on infrastructure and,
subject to shareholder approval, intends to change the name of ETSI to
InfraCorps Inc. ETSI also changed its fiscal year-end from May 31 to March 31.

         ETSI operates its infrastructure business through two wholly-owned
affiliates: InfraCorps of Virginia, Inc. (formerly ETS Water and Waste
Management, Inc.) ("ETSW") and InfraCorps of Florida, Inc. (formerly ETS Liner,
Inc.) ("ETSL"), a subsidiary of ETSW. In connection with its restructuring, ETSI
during fiscal 1998 sold substantially all of the assets of IC Subsidiary, Inc.
(formerly ETS, Inc.) ("ETS") and ETS Analytical Services, Inc. ("ETSAS"), as
described below. As a result of these sales, neither ETS nor ETSAS, which are
wholly-owned subsidiaries of ETSI, currently is engaged in active business
operations.

         On March 6, 1998, the common stock of ETSI was delisted from the
Emerging Company Marketplace (the "EMC") of the American Stock Exchange
("AMEX"). This action became necessary because ETSI was unable to achieve
compliance with the EMC's financial guidelines for continued listing. The common
stock of ETSI presently is quoted on the OTC Bulletin Board under the symbol
ETSI.

         InfraCorps of Virginia, Inc. (formerly ETS Water and Waste Management,
Inc.) ("ETSW"), a Virginia corporation headquartered in Richmond, Virginia, is
ETSI's construction subsidiary. ETSW was formed as a result of ETSI's
acquisition on June 1, 1994, of Stamie E. Lyttle Company, Inc., Lyttle
Utilities, Inc. and LPS Corporation. The three firms, the history of which dates
back to 1947, were consolidated into one corporation, ETSW. ETSW, along with its
subsidiary, InfraCorps of Florida, Inc. (formerly ETS Liner, Inc.) ("ETSL"), a
Virginia corporation headquartered in Orlando, Florida, utilizes trenchless
technologies to install and rehabilitate subsurface pipelines. ETSI's
infrastructure customers include municipalities, government agencies, Fortune
500 companies and developers. ETSW, through its Service Division, also designed
and installed septic and irrigation systems and provided related repair and
maintenance services. As part of ETSI's effort to focus on the infrastructure
business, ETSI, in April 1998, sold the Service Division of ETSW to a new
corporation formed by Coleman S. Lyttle, a director of ETSI and President of
ETSW.

         IC Subsidiary, Inc. (formerly ETS, Inc.) ("ETS"), a Virginia
corporation, was ETSI's environmental products and services subsidiary. On March
12, 1998, ETSI completed the sale of substantially all of the assets of ETS to
ETS Acquisition, Inc. In connection with the sale, ETSI sold a portion of its
assets and liabilities relating to the Limestone Emission Control ("LEC")
technology, including patents and licenses, to Christel Clear Technologies, Inc.
("CCTI"). Both ETS Acquisition and CCTI are newly formed entities owned by John
D. McKenna, Arthur B. Nunn, III and John C. Mycock (the "Buyers"), former
executive officers and former directors of ETSI. Related to this transaction,
ETSI also entered into a management agreement with Air Technologies, Inc.
("ATI"), another newly formed entity owned by the Buyers, pursuant to which ATI
provides services with respect to ETSI's contract to supply to China Steel
Corporation sulfur dioxide removal systems utilizing the LEC technology (the
"CSC Contract"). ATI and CCTI have agreed to use their best efforts to have the
CSC Contract assigned without recourse from ETSI to ATI. Negotiations in this
regard are presently underway with China Steel

                                        3

Corporation. If these negotiations are not successful, ETSI will continue to be
subject to potential liabilities and losses in connection with the environmental
technology being developed in connection with the CSC Contract.

         ETS Analytical Services, Inc. ("ETSAS"), a Virginia corporation,
operated as the environmental analytical laboratory subsidiary of ETSI. In
October 1997, ETSI sold substantially all of the assets of ETSAS to Q
Enterprises, Inc., a company owned by James B. Quarles, a former employee and
Senior Vice President of ETSI. Mr. Quarles has since become President and Chief
Executive Officer of ETSI and sold his interest in Q Enterprises, Inc.

         ETSI's principal executive offices are located at 7400 Beaufont Springs
Drive, Suite 415, Richmond, Virginia 23225, and its telephone number is (804)
272-6600.


                               MARKET INFORMATION

         Prior to March 6, 1998, the Common Stock of ETSI was listed and
registered on the Emerging Company Marketplace ("EMC") of the American Stock

of ETSI was delisted from the AMEX-EMC because ETSI was unable to achieve
compliance with the EMC's financial guidelines for continued listing. The Common
Stock of ETSI currently trades in the over-the-counter market and is quoted

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

Overview

         On January 20, 1998, ETSI announced a management reorganization,
pursuant to which James B. Quarles was elected President and Chief Executive
Officer of ETSI and was appointed to its Board of Directors. Navin D. Sheth, the
Chief Operating Officer of ETSW, a wholly owned subsidiary of ETSI, was
appointed Chief Financial Officer of ETSI. John D. McKenna resigned as President
and Chief Executive Officer of ETSI on that date. Further, in connection with
on-going negotiations to purchase substantially all the assets of ETSI's wholly
owned environmental subsidiary, ETS, John D. McKenna, Arthur B. Nunn, III and
John C. Mycock resigned from ETSI's Board of Directors effective February 2,
1998. These resignations were not the result of a disagreement on any

                                        5

<PAGE>




matter relating to ETSI's operations, policies or practices. In light of these
resignations, James B. Quarles was elected Chairman of the Board, in addition to
his position as President and Chief Executive Officer.

         The management reorganization reflects ETSI's intention to focus on its
infrastructure lines of business and to de-emphasize its environmental products
and services. New management believes that the environmental services aspect of
ETSI historically has been a break-even business, providing little value to
shareholders, while attempts to commercialize the environmental technologies
aspect of ETSI have been a drain on ETSI's limited capital resources. Management
believes that ETSI should focus on one line of business -- the installation and
rehabilitation of subsurface pipelines for the transmission of water, waste and
natural gas -- and is seeking to position ETSI to take advantage of perceived
growth opportunities within that industry segment. There can, however, be no
assurance that the Company's refocusing efforts will be successful.

         ETSI is seeking shareholder approval at its Annual Meeting of
Shareholders, to be held on August 17, 1998, to formally change its name to
InfraCorps Inc. Pending shareholder approval of the formal name change, the
Company has filed a fictitious name certificate to conduct business in Virginia
as InfraCorps Inc. On April 9, 1998, the Company relocated its headquarters to
Richmond, Virginia, where its construction subsidiary, ETSW, is based. Effective
May 22, 1998, ETSI changed the names of its wholly owned subsidiaries, ETSW and
ETS, to InfraCorps of Virginia, Inc. and IC Subsidiary, Inc., respectively. The
name of ETSL was changed to InfraCorps of Florida, Inc. effective May 21, 1998.

         On October 31, 1997, ETSI sold substantially all of the assets and
certain liabilities of ETSAS to Q Enterprises, Inc., a company owned by James B.
Quarles, a former employee and Senior Vice President of ETSI. Mr. Quarles has
since become President and Chief Executive Officer of ETSI and sold his interest
in Q Enterprises, Inc. Since the risks of ownership were not transferred to Q
Enterprises, Inc., no sale was recognized for accounting purposes. Accordingly,
the assets and liabilities transferred to Q Enterprises, Inc. are shown in the
noncurrent sections of the balance sheet and are designated as "assets of
business transferred under contractual arrangements" and "liabilities of
business transferred under contractual arrangements." ETSI received an 8.5%
promissory note in the amount of $1,000,000 with payments amortized over 30
years with a balloon payment after 10 years. As payments of principal and
interest are received, they are being recorded as a reduction to "assets of
business transferred under contractual arrangements" until such time as ETSI
determines a sale can be recorded for accounting purposes. At March 31, 1998,
"assets of business transferred under contractual arrangements" of $267,666 are
stated net of a valuation allowance of $858,000. The conversion of these assets
to cash is dependent on the future profitable operations of Q Enterprises, Inc.
A loss on disposal of these discontinued environmental operations of $878,326
was recorded.

         On March 6, 1998, ETSI Common Stock was removed from listing and
registration on the AMEX-EMC because ETSI was unable to achieve compliance with
the EMC continued listing guidelines. ETSI's Common Stock currently is quoted on
the OTC Bulletin Board under the symbol ETSI. See "Market Information."

         On March 12, 1998, substantially all of the assets of ETS were sold to
ETS Acquisition, Inc., a newly formed firm based in Roanoke, Virginia. In
connection with this sale, ETSI sold a portion of its assets and business
relating to the LEC technology, including patents and licenses, to CCTI, a newly
formed firm based in Roanoke, Virginia. The total purchase price was
approximately $1,896,000 for all of the aforementioned. The purchase price was
paid in cash, stock of ETSI, assumption of certain liabilities of ETS, delivery
of a 30-day note bearing 8 1/2% interest and delivery of a 10-year note bearing
8 1/2% interest, and ETSI will receive 50% of all royalties received by CCTI in
connection with the license of the LEC technology. While there is no indication
that the LEC will be resold by CCTI, the agreement further provides that ETSI
will receive 50% of the net sales price from a resale of the LEC technology on
or before March 12, 1999, and 25% of the net sales price from a resale after
March 12, 1999 but on or before March 12, 2000. A loss on disposal of these
discontinued environmental operations of $513,547 was recorded.


                                        6

<PAGE>




         In connection with the foregoing transaction, ETSI entered into a
Management Agreement with ATI, a newly formed firm based in Roanoke, Virginia,
to provide management services with respect to ETSI's contract with China Steel
Corporation. ETS Acquisition, Inc., CCTI and ATI are owned by John D. McKenna,
Arthur B. Nunn, III and John C. Mycock, three former executive officers of ETSI
and former members of ETSI's Board of Directors.

         ATI and CCTI have agreed to accept responsibility for any potential
liabilities associated with the CSC Contract and to provide their best efforts
to have the CSC Contract assigned without recourse from ETSI to ATI. However,
although negotiations are underway with China Steel Corporation, ETSI has not
yet been successful in obtaining assignment of the CSC Contract. Accordingly,
ETSI still has potential liability under the CSC Contract which could have a
material negative impact on ETSI's business operations. Potential issues have
been brought to current management's attention regarding the budget to meet
certain of the performance specifications of the CSC Contract and the overall
viability of the LEC technology for wide-scale commercialization. If the LEC
technology does not meet contract specifications, China Steel Corporation may
seek to impose financial penalties or attempt to recover damages or obtain other
relief under the CSC Contract, including drawing down on the $600,000
performance bond posted by ETSI.

Result of Operations

         On April 6, 1998, the Board of Directors changed the fiscal year-end of
the Company from May 31 to March 31. Accordingly, the March 31, 1998 operating
results of ETSI are for a ten-month period; therefore the Company will compare
its results of operations for the ten-month period ended March 31, 1998 with its
results of operations for the ten-month period ended March 31, 1997. See Note 16
of Notes to Consolidated Financial Statements for unaudited results of
operations for the ten-month period ended March 31, 1997.

Ten Months Ended March 31, 1998 compared to Ten Months Ended March 31, 1997

         Revenues for the ten-month period ended March 31, 1998 were $12,644,431
from continuing infrastructure operations compared to $14,219,865 for the
ten-month period ended March 31, 1997, for a 11% decrease. This decrease mainly
was due to lower billings resulting from the unseasonably wet weather
experienced during the last four months of fiscal 1998.

         Cost of goods and services was $10,678,548 or 84.5% of total revenues
for the ten-month period ended March 31, 1998, compared to $11,834,222 or 83.2%
of the total revenues for the same period ended March 31, 1997. Gross profit for
the current ten-month period was $1,965,883 or 15.5% of total revenues compared
to $2,385,643 or 16.8% of total revenues for the ten months ended March 31,
1997. These decreases were due primarily to the unseasonably wet weather, which
increased downtime and the cost of completing projects.

         Selling, general and administrative expenses for the ten-month period
ended March 31, 1998 were $2,747,336 or 21.7% of revenues compared to $2,246,981
or 15.8% of revenues for the same period ended March 31, 1997. The increase in
selling, general and administrative expenses primarily was due to higher costs
associated with attempts to increase sales in the "pipe bursting" division and
additional costs incurred to relocate ETSL to Orlando, Florida.

         Interest income from certificates of deposits for the ten-month period
ended March 31, 1998 was $19,842 compared to $15,729 for the same period in
1997. Interest expense for the ten-month period ended March 31, 1998 was
$758,566 as compared to $166,856 for the same period last year. The increase is
due to increased loans outstanding of approximately $1.2 million and interest
costs associated with ETSI's convertible debentures. Gain (loss) on sale of
equipment was ($14,264) for the current ten-month period compared to $101,037
for the same period last year.

         Loss from continuing operations for the ten-month period ended March
31, 1998 was $1,536,104 compared to profit of $89,299 for the same period last
year. Such loss reflects lower revenues, increased selling, general and
administrative expenses and increased interest expense during fiscal 1998.

         Loss from discontinued operations was $1,879,374 for the ten-month
period ended March 31, 1998 compared to $566,793 for the same period in 1997.
These discontinued operations were the analytical laboratory and environmental
services. The environmental operations had revenues of $2,640,195 for the
ten-month period. Increased competition among analytical laboratories created
tight margins and lower revenues. As such, the analytical laboratory was unable
to show a profit. The commercialization of the LEC technology caused a drain on
the profits of the environmental services operations. As a result, ETSI
considered the environmental services operations no longer viable and disposed
of these operations. Loss on disposal of discontinued operations was $1,391,873,
with a loss of $878,326 having been incurred on the sale of the assets of ETSAS
and a loss of $513,547 having been incurred on the sale of the assets of ETS.

Fiscal Year ended May 31, 1997 Compared to Fiscal Year ended May 31, 1996

         Revenues from infrastructure services for the fiscal year ended May 31,
1997 ("fiscal 1997") were $18,518,127 compared to revenues of $14,042,804 for
the fiscal year ended May 31, 1996 ("fiscal 1996"), representing a 31.9%
increase. ETSI showed a substantial increase in revenues for fiscal 1997 as a
result of an increase in the construction division, which experienced greater
activity in the Richmond, Virginia area. The service area revenues in fiscal
1997 remained about the same, while the irrigation business was lower in fiscal
1997 due to a changed focus from residential irrigation to commercial
irrigation. The major area of improvement in fiscal 1997 was the rehabilitation
of subsurface pipelines, where the market appeared to be getting stronger.

         Cost of goods and services were $15,397,182 or 83.1% of total revenues
for fiscal 1997 compared to $13,164,032 or 93.7% of total revenues for fiscal
1996. This decrease in cost as a percentage of revenues in fiscal 1997 was the
result of increased efforts to cut costs and sell contracts that are more
profitable.

         Gross profits in fiscal 1997 were $3,120,945 or 16.9% of revenues
compared to $878,772 or 6.3% of revenues in fiscal 1996. This increase in gross
profits reflected the increase in sales and the lower cost of those sales.

         Selling, general and administrative expenses for fiscal 1997 were
$2,205,948 or 11.9% of revenues compared to $2,061,346 or 14.6% of fiscal 1996
revenues. This decrease in cost as a percentage of revenues was largely the
result of ETSI's cost control efforts.

         Interest income from savings on deposit for fiscal 1997 was $20,024
compared to $21,107 for fiscal 1996. Interest expense for fiscal 1997 was
$385,969, compared to interest expense of $213,934 for fiscal 1996. The increase
in expense in fiscal 1997 was due to higher interest costs associated with
ETSI's convertible debentures. Gain (loss) on sale of equipment was $101,037 for
fiscal 1997 compared to ($1,925) for fiscal 1996.

         Loss from discontinued operations for fiscal 1997 was $502,380 compared
to $627,947 for fiscal 1996. This decrease in fiscal 1997 was due to an effort
to control costs of the environmental operations, plus the reimbursement of
approximately $225,000 of costs expended for engineering services as a result of
audits completed by the EPA.

         Net income for fiscal 1997 was $148,435 compared to a loss of
$1,998,791 for fiscal 1996. In fiscal 1997, the construction company experienced
a substantial increase in contract revenues of $4,475,323, which resulted in
income from continuing operations of $650,815. This amount was sufficient to
offset the substantial loss of $502,380 experienced by the environmental
operations in fiscal 1997. In fiscal 1996, the construction company experienced
a net loss of $1,370,844, and the environmental operations experienced a net
loss of $627,947.

Liquidity And Capital Resources As of March 31, 1998

         ETSI is capital deficient, having invested heavily in its attempts to
commercialize the LEC system on an international level and having failed to
raise additional funds with which to go forward in a weak environmental
marketplace. ETSI experienced a substantial loss of $4,807,351 for the
ten-months ended March 31, 1998. Stockholders' deficit at March 31, 1998 was
$713,619, which represents a decrease of $3,683,142 from stockholders' equity of
$2,969,523 at May 31, 1997. ETSI's current liabilities of $7,734,434 exceeded
its current assets of $4,665,184 by $3,069,250 at March 31, 1998.

         During fiscal 1998, ETSI concluded that it was in the Company's best
interest to de-emphasize its environmental products and services and to focus on
its construction operations, particularly with respect to the installation and
rehabilitation of subsurface pipelines for the transmission of water, waste and
natural gas. Management currently is negotiating with certain note holders to
convert debt of approximately $4,000,000 to preferred stock and to obtain a line
of credit from a bank. Management's success in these regards will, to a large
extent, depend upon whether ETSI is able to accomplish the assignment without
recourse of the CSC Contract to ATI. While negotiations with China Steel
Corporation are on-going, there can be no assurance that such negotiations will
be successful or that ETSI will find sufficient sources of outside capital to
support its future operations. See Note 19 of Notes to Consolidated Financial
Statements.

         Effective May 1, 1998, ETSI restructured its credit facility with
Thomas W. Marmon, a former director and a large shareholder of ETSI. The new
note for the credit facility, which in part is a renewal of the previous note,
permits total aggregate borrowings by ETSI of up to $3.5 million. The new note
provides for monthly interest payments at a rate of 10% until the credit
facility's maturity at May 1, 1999 and 12% thereafter and is subject to call by
the holder upon sixty days written notice. At March 31, 1998, the principal
amount outstanding on the credit facility was approximately $3.1 million (which
included unpaid interest of $210,000 as part of principal). The new note is
secured by the assets of ETSI and its subsidiaries. Mr. Marmon resigned as a
director of ETSI as of April 13, 1998, in order to eliminate concerns regarding
his conflict of interest in certain circumstances. Mr. Marmon's resignation is
not the result of a disagreement with ETSI on any matter relating to ETSI's
operations, policies or practices.

         On April 28, 1998, ETSI sold the Service Division of ETSW (e.g., septic
system installation and repair, irrigation, plumbing, jacuzzi service contracts
and incidental concrete manufacturing/concrete products) to a new corporation
formed by Coleman S. Lyttle, a director of ETSI and President of ETSW, for a
total purchase price of $700,000, payable as follows: $350,000 cash at closing,
assumption of certain indebtness of ETSW and notes payable to ETSW in the
aggregate amount of $250,000.

         Net cash used in operating activities for the ten months ended March
31, 1998 consisted mainly of the net loss of $4,807,351. There was a general
decrease in assets and liabilities due to the sales of ETS and ETSAS.

         Net cash used in investing activities during the ten months ended March
31, 1998 primarily represents purchases of new "pipe bursting" equipment for
ETSI's infrastructure operation in Florida, the cost of which was offset by
proceeds received from the sale of discontinued operations during the same
period. Cash provided by financing during the ten months ended March 31, 1998
came from loans from shareholders of $1,410,000, an increase of $775,542 in
loans from affiliates, and proceeds from long-term debt of $645,036.

         New orders received for the ten-month period ended March 31, 1998
totaled $12,883,266 as compared to $14,917,207 for the same period in 1997. The
new orders for the ten-month period ended March 31, 1998 were down, reflecting
the slow period in the second quarter of fiscal 1998. Backlog at March 31, 1998
was $5,527,124, compared to $4,770,106 at March 31, 1997.

         Subsequent to the fiscal 1998 year-end, ETSW was awarded a $4,000,000
contract for pipeline work to be performed on behalf of the City of Petersburg,
Virginia. In addition, Motorola Corporation awarded ETSW a

                                        9

<PAGE>




contract to perform approximately $1,000,000 of pipeline work. ETSW's authorized
backlog was approximately $12,000,000 at May 31, 1998.

Year 2000

         ETSI has contacted its software vendors about upgrading its computer
systems and applications to be Year 2000 compliant. ETSI expects conversion and
testing to be completed during fiscal 1999. There were no expenditures during
fiscal year 1998 related to the Year 2000 upgrades and, based on estimates
provided by software vendors, the cost of making the systems and applications
Year 2000 compliant are not currently expected to be significant to the
consolidated financial statements.

Recent Accounting Developments

         Recently, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, Reporting Comprehensive Income, and
Statement of Financial Accounting Standards No. 131, Disclosures about Segments
of an Enterprise and Related Information. These statements are effective for
fiscal years beginning after December 15, 1997. The Company does not anticipate
that the adoption of these statements will have a material effect on its
financial position or results of operations.

                          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 March 31, 1998 and May 31, 1997, and
the related consolidated statements of income (loss), stockholders' equity
(deficit) and cash flows for the ten-month period ended March 31, 1998 and years
ended May 31, 1997 and 1996. 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 March 31, 1998 and May 31, 1997, and the results of
their operations and their cash flows for the ten-month period ended March 31,
1998 and years ended May 31, 1997 and 1996, in conformity with generally
accepted accounting principles.

The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern. As discussed in note 19 to
the consolidated financial statements, the Company has suffered losses from
operations and has a net capital deficiency that raise substantial doubt about
its ability to continue as a going concern. Management's plans in regard to
these matters are also described in note 19. The consolidated financial
statements do not include any adjustments that might result from the outcome of
this uncertainty.

As of March 31, 1998 and May 31, 1997 and Ten-month Period Ended March 31, 1998
and Years Ended May 31, 1997 and 1996

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


(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. During fiscal 1998,
         substantially all assets and certain liabilities of ETS, Inc. and ETS
         Analytical Services, Inc. were sold. See note 10 for additional
         information.

         Change in Fiscal Year

         On April 6, 1998, the Company's fiscal year end was changed from May 31
         to March 31. As a result, these consolidated financial statements cover
         the ten-month transition period from June 1, 1997 to March 31, 1998.
         The Company's next full year will be from April 1, 1998 to March 31,
         1999.

         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 ($471,166 in 1998 and $351,856
         in 1997) and supplies ($460,424 in 1998 and $419,932 in 1997), 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.
                                                                     (Continued)

(1)      (Continued)

         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.

         Provisions for depreciation and amortization have been calculated using
         the straight line method over the following estimated useful lives of
         the assets:

                   Furniture and fixtures             5 - 10 years
                   Laboratory equipment               5 - 10 years
                   Tools and equipment                5 - 10 years
                   Vehicles                           3 - 5 years
                   Leasehold improvements             5 - 31 years

         Property and equipment under capital leases are amortized on the
         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



                                                                     (Continued)

         flows using a discount rate reflecting the Company's average cost of
         funds. Due to impairment, $104,754 of goodwill was written off in 1998.

         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

         In February 1997, the Financial Accounting Standards Board issued
         Statement of Financial Accounting Standards No. 128, Earnings per
         Share. Statement 128 establishes new standards for computing and
         presenting earnings per share (EPS) and applies to entities with
         publicly held common stock or potential common stock. It replaces the
         presentation of primary EPS with a presentation of basic EPS. It also
         requires dual presentation of basic and diluted EPS on the face of the
         income statement for all entities with complex capital structures and
         requires a reconciliation of the numerator and denominator of the basic
         EPS computation to the numerator and denominator of the diluted EPS
         computation. Basic EPS excludes dilution and is computed by dividing
         income available to common stockholders by the weighted-average number
         of common shares outstanding for the period. Diluted EPS reflects the
         potential dilution that could occur if securities or other contracts to
         issue common stock were exercised or converted into common stock or
         resulted in the issuance of common stock that then shared in the
         earnings of the entity. Statement 128 was adopted by the Company at
         February 28, 1998. The Statement requires restatement of prior years
         EPS data previously presented. Adoption of this Statement did not have
         a material effect on current or prior years' EPS data presented.








                                                                     (Continued)

(1)      (Continued)

         Basic earnings per share have been computed on the basis of weighted
         average number of shares outstanding. Diluted earnings per share
         included 46,931 shares related to stock options and warrants for the
         year ended May 31, 1997, due to their dilutive effect. Diluted earnings
         per share did not include shares related to stock options and warrants
         for the ten-month period ended March 31, 1998 and for the year ended
         May 31, 1996 and did not include any shares related to convertible
         debentures for any of the periods as their effect was antidilutive. See
         note 11 for information relating to stock options and warrants that
         could potentially dilute basic earnings per share in the future. See
         earnings per share information included on consolidated statements of
         income (loss).

         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 periods. Actual results
         could differ from these estimates.

         Reclassifications

         Certain reclassifications have been made to the prior years'
         consolidated financial statements to conform to classifications used in
         1998.




                                                                     (Continued)

(2)      Restricted Cash

         Included in restricted cash is $600,000 relating to a performance bond
         relating to the Company's contract with China Steel Corporation (the
         "China Steel Contract"). The Board of Directors of the Company is
         continuing to review the financial and other aspects of the Limestone
         Emission Control ("LEC") technology that is being developed for the
         China Steel Contract. This review was undertaken after potential issues
         were brought to current management's attention regarding the budget to
         meet certain of the performance specifications of the China Steel
         Contract and the overall viability of the LEC technology for wide-scale
         commercialization. If the LEC technology does not meet contract
         specifications, China Steel Corporation may seek to impose financial
         penalties or attempt to recover damages or obtain other relief under
         the contract, including drawing down on the $600,000 performance bond
         posted by the Company.

(3)      Business Combinations

         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.

         The following table summarizes these acquisitions:


                                                                         1996

(6)      (Continued)

         Aggregate debt maturities for each of the next four years ending on
         March 31 is as follows: 1999, $480,543; 2000, $327,760; 2001, $302,605;
         2002, $179,840 and 2003, $97,691, respectively.

         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 using the interest method; $438,028
         in 1998 and $139,152 in 1997.

         On May 20, 1997, the Company issued 145,335 shares of common stock upon
         the conversion of $50,776 of the convertible debentures, including $776
         of accrued interest. During 1998, the Company issued 2,486,655 shares
         of common stock upon the conversion of $768,710 of the convertible
         debentures, including $68,710 of accrued interest.

         Rent expense for operating leases of approximately $1,001,000,

         March 31, 1998 and the years ended May 31, 1997 and 1996, respectively.

         On October 25, 1995, the Company entered into a sale/leaseback
         agreement which provided for the sale and leaseback of certain
         equipment. This equipment, with a net book value of $443,668, was sold
         for $1,660,900 and was leased back to the Company for a 48-month period
         at $39,015 per month. The resulting gain of $1,217,232 on the sale of
         equipment is being amortized over the life of the operating lease and
         has a remaining balance of $481,821 at March 31, 1998.

(8)      Common Stock Subject to Repurchase Agreement

         In connection with the Olympic Industries, Inc. asset acquisition (see
         note 3), 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 (269,565 shares) on the first anniversary of the acquisition and
         up to one-half of the issued shares (269,565) on the second anniversary
         of the acquisition.


                                                                     (Continued)

         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).

         In February 1997, the first anniversary of the acquisition, Olympic
         Industries, Inc. elected to have the Company repurchase one-half of the
         issued shares (269,565 shares). Accordingly, this obligation of
         $409,642 including interest of $22,142 is shown as current. The Company
         completed the repurchase in fiscal 1998.

         In August 1997, Olympic Industries, Inc. agreed to retain the remaining
         269,565 shares and this common stock subject to repurchase of $387,500
         was reclassified to stockholders' equity.

(9)      Income Taxes

         The Company is in a net operating loss position, accordingly, no income
         tax expense (benefit) has been recognized for the ten-month period
         ended March 31, 1998 and years ended May 31, 1997 and 1996.

         Income tax expense (benefit) differs from the amount computed by
         applying the statutory corporate tax rate of 34 percent to income
         (loss) including loss from discontinued operations and loss on disposal
         of discontinued operations before income taxes as follows:

         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.

         At March 31, 1998, the Company has loss carryforwards for income tax
         purposes of $5,344,137 available to offset future taxable income. If
         not utilized, these loss carryforwards will expire as follows:

         In addition, the Company has various tax credit carryforwards of
         approximately $27,000 which will expire between the years 1998 and
         2000.

(10)     Disposal of Environmental Operations Segment

         During the ten-month period ended March 31, 1998, the Company disposed
         of its environmental operations segment. In October 1997, the Company
         sold substantially all of the assets and certain liabilities of ETS
         Analytical Services, Inc. ("ETSAS"), a wholly-owned subsidiary, to Q
         Enterprises, Inc. ("Q Enterprises"), a company owned by James B.
         Quarles, a former employee and senior vice president of ETS
         International, Inc. Mr. Quarles has since become president and chief
         executive officer of the Company and sold his interest in Q
         Enterprises. Since the risks of ownership were not transferred to Q
         Enterprises, no sale was recognized for accounting purposes.
         Accordingly, the assets and liabilities transferred to Q Enterprises
         are shown in the noncurrent sections of the balance sheet and are
         designated as "assets of business transferred under contractual
         arrangements" and "liabilities of business transferred under
         contractual arrangements." The Company received an 8.5 percent
         promissory note in the amount of $1,000,000 with payments amortized
         over 30 years with a balloon payment after 10 years. As payments of
         principal and interest are received, they are being recorded as a
         reduction to "assets of business transferred under contractual
         arrangements" until such time the Company determines a sale can be
         recorded for accounting purposes. At March 31, 1998,"Assets of business
         transferred under contractual arrangements" of $267,666 are stated net
         of a valuation allowance of 858,000. The conversion of these assets to
         cash is dependent on the future profitable operations of Q Enterprises.
         A loss on disposal of these discontinued environmental operations of
         $878,326 was recorded.

         In March 1998, substantially all of the assets and certain liabilities
         of ETS, Inc. ("ETS"), a wholly owned subsidiary, were sold to ETS
         Acquisition, Inc., a newly-formed firm. In connection with this sale,
         the Company sold a portion of its assets and business relating to the
         Limestone Emission Control (LEC) technology, including patents and
         licenses, to Christel Clear Technologies, Inc. ("CCTI"), a newly formed
         firm. The total purchase price was approximately $1,896,000 for all of
         the aforementioned. The purchase price was paid in cash, stock of the
         Company, assumption of certain liabilities of ETS, and delivery of a
         $200,000 thirty-day note and a $100,000 ten-year note both bearing
         8-1/2 percent interest. Also, the Company will receive 50 percent of
         all royalties received by CCTI in connection with the license of the
         LEC technology. While there is no indication that the LEC will be
         resold by CCTI, the agreement further provides that the Company will
         receive 50 percent of the net sales price from a resale of the LEC
         technology on or before March 12, 1999, and 25 percent of the net sales
         price from a resale after March 12, 1999 but on or before March 12,
         2000. A loss on disposal of these discontinued environmental operations
         of $513,547 was recorded.




                                                                     (Continued)

         In connection with the sale discussed in the preceding paragraph, the
         Company entered into a Management Agreement with Air Technologies, Inc.
         ("ATI"), a newly-formed firm, to provide management services with
         respect to the Company's contract with China Steel Corporation (the
         "China Steel Contract"). ATI and CCTI agreed to accept responsibility
         for any potential liabilities associated with the China Steel Contract
         and to provide its best effort to have the contract transferred from
         the Company to ATI. ETS Acquisition, Inc., CCTI and ATI are owned by
         John D. McKenna, Arthur B. Nunn, III and John C. Mycock, three former
         executive officers of the Company and former members of the Company's
         Board of Directors. See note 2 for additional information.

         Also in connection with the disposal of the environmental operations,
         the Company has allocated interest costs to loss on discontinued
         operations. Interest costs allocated to discontinued operations
         includes interest on debt directly attributable to the environmental
         operations, which was assumed by the buyers, and other consolidated
         interest not directly attributable to any of the Company's other
         operations. Other consolidated interest was allocated based on the
         ratio of net assets sold to the sum of total net assets of the
         consolidated Company plus consolidated debt not directly attributed to
         other operations of the Company. Interest costs allocated to
         discontinued operations were $301,678, $186,860 and $178,197 for the
         ten-month period ended March 31, 1998 and the years ended May 31, 1997
         and 1996, respectively.

(11)     Stock Options and Warrants

         Pursuant to various stock option and stock warrant agreements, the
         Company has granted nontransferable options and warrants to acquire the
         Company's common stock to certain officers, directors, investors,
         vendors and employees of the Company and its subsidiaries. Options and
         warrants are generally granted at approximate fair market value based
         on the higher of the most recent ten-day average price of the stock or
         the last day's closing price of the stock on the date of the grant.
         Options generally become exercisable over a period not exceeding five
         years from date of grant and warrants are exercisable upon issuance.

         The aggregate amount of shares under option pursuant to these
         agreements were as follows:

         In 1998, stock options for 400,000 shares were granted to the president
         at an exercise price of $.27, which was $.11 per share below the market
         value on the date of grant. These shares have not been exercised but
         compensation expense of $44,000 was recorded which represents the
         difference between the exercise price and the market value on date of
         grant.

         In 1997, 212,000 options were granted and exercised at $.005. At the
         time the options were granted, the common stock of the Company had a
         fair value of $.63. These options were granted in exchange for
         services. The services were recorded at the difference between the
         option price and fair value of the common stock.

         The per share weighted average fair values of stock options and
         warrants granted during 1998, 1997 and 1996 were $.16, $.29 and $.18,
         respectively, on the various dates of grant using the Black-Scholes
         option pricing model with the following weighted average assumptions:
         1998 - expected dividend yield of 0 percent, risk-free interest rate
         ranging from 5.50 percent to 6.39 percent, expected volatility of 20
         percent and an expected life of 5 years; 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 1998, 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.

(12)     Related Party Transactions

         During a portion of fiscal year 1998, the Company occupied office and
         laboratory space under lease agreements with its former subsidiaries,
         ETS, Inc. and ETS Analytical Services, Inc. ("ETSAS"). These facilities
         were leased from entities whose members included former officers and
         directors of the Company. As a result of the sale of the Company's
         subsidiaries, ETS, Inc. and ETSAS, these leases were effectively
         assigned to other parties during fiscal year 1998. The Company also
         leases the premises of its subsidiary, ETS Water and Waste Management,
         from an estate in which a current director serves as executor. Rent
         expense under these operating leases approximated $258,000, $417,000
         and $405,000 for 1998, 1997 and 1996, respectively.

         Other accounts receivable consists primarily of advances to officers,
         directors and other employees. At March 31, 1998 and May 31, 1997,
         $32,918 and $91,381, respectively, were the result of these advances.

         The Company has notes receivable from officers and employees of
         $344,152 and $408,846 as of March 31, 1998 and May 31, 1997,
         respectively. The notes bear interest at six percent.

         The Company has notes payable to affiliates of $966,159 and $490,617 as
         of March 31, 1998 and May 31, 1997, respectively. These affiliates
         include certain partnerships and individuals whose members are officers
         and directors of the Company. The notes bear interest at rates between
         six and twenty percent.

         In March 1997, the Company borrowed $2,000,000 from a stockholder,
         Thomas W. Marmon. 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 at May
         31, 1997. The note bears interest at fifteen percent which is payable
         monthly.









                                                                     (Continued)

(12)     (Continued)

         The Company, in May 1998, entered into an agreement in principle to
         restructure its credit facility with Thomas W. Marmon, a former
         director and a large stockholder of the Company. The new note for the
         credit facility, which in part is a renewal of the previous note,
         permits total aggregate borrowing by the Company of up to $3,500,000.
         The new note will provide for monthly interest payments at a rate of 10
         percent until the facility's maturity at May 1, 1999 and 12 percent
         thereafter. The note is subject to call by the holder upon sixty days
         written notice. Due to this acceleration clause, the entire amount is
         shown as current at March 31, 1998. At March 31, 1998, the amount
         outstanding under the credit facility was $2,860,000, plus accrued
         interest of $210,000 which is payable on June 1, 1998. The new note is
         secured by the assets of the Company and its subsidiaries. Mr. Marmon
         resigned as a director of the Company as of April 13, 1998.

         In addition, the Company had $550,000 of notes payable to two
         stockholders at March 31, 1998 with due dates in fiscal 1999. Interest
         is payable monthly at rates ranging from 10 percent to 12 percent per
         annum.
         The notes are unsecured.

(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)     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.





                                                                     (Continued)

(15)     Contingencies

         The Company does not receive hazardous waste during the normal course
         of business. Until the Company's environmental operations were sold in
         fiscal 1998, it received environmental samples for analysis; and,
         occasionally, in the process of analysis, small quantities of hazardous
         waste were generated. Such waste was stored in designated 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 was engaged in field testing. It was
         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 litigation or environmental matters currently existing
         which would have a material impact on the financial position or results
         of operations of the Company.

         See notes 2 and 10 for contingencies related to the China Steel
         Contract.

(16)     Comparable Prior Period Income Statement Information (Unaudited)

         As described in note 1, on April 6, 1998, the Company changed its
         fiscal year from May 31 to March 31. Comparable results of operations
         for the ten-month period ended March 31, 1997 follows:

(17)     Future Accounting Considerations

         In June 1997, the Financial Accounting Standards Board (FASB) issued
         Statement of Financial Accounting Standards No. 130, Reporting
         Comprehensive Income. Statement 130 establishes standards for reporting
         and display of comprehensive income and its components (revenues,
         expenses, gains and losses) in a full set of general purpose financial
         statements. Statement 130 was issued to address concerns over the
         practice of reporting elements of comprehensive income directly in
         equity.

         This Statement requires all items that are required to be recognized
         under accounting standards as components of comprehensive income be
         reported in a financial statement that is displayed in equal prominence
         with the other financial statements. It does not require a specific
         format for that financial statement but requires that an enterprise
         display an amount representing total comprehensive income for the
         period in that financial statement. Enterprises are required to
         classify items of "other comprehensive income" by their nature in the
         financial statement and display the accumulated balance of other
         comprehensive income separately from retained earnings and additional
         paid-in capital in the equity section of a statement of financial
         position. It does not require per share amounts of comprehensive income
         to be disclosed.

         Statement 130 is effective for fiscal years beginning after December
         15, 1997. Earlier application is permitted. Comparative financial
         statements provided for earlier periods are required to be reclassified
         to reflect the provisions of this statement. Publicly traded
         enterprises that issue condensed financial statements for interim
         periods are required to report a total for comprehensive income in
         those financial statements.

         Adoption of Statement 130 on April 1, 1998 will not have any effect on
         the Company's consolidated financial position, results of operation or
         liquidity.

         In June 1997, the FASB issued Statement No. 131, Disclosures about
         Segments of an Enterprise and Related Information. Statement 131
         establishes standards for the way public business enterprises are to
         report information about operating segments in annual financial
         statements and requires those enterprises to report selected
         information about operating segments in interim financial reports
         issued to shareholders. It also establishes standards for related
         disclosures about products and services, geographic areas and major
         customers. Statement 131 is effective for financial statements for
         periods beginning after December 15, 1997. It is not anticipated that
         Statement 131 will have a material effect on current or prior period
         disclosures presented by the Company.

(18)     Sale of Service Division of ETS Water and Waste Management, Inc.
         ("ETSW")

         On April 28, 1998, the Company sold the Service Division of ETSW (e.g.,
         septic system installation and repair, irrigation, plumbing, jacuzzi
         service contracts and incidental concrete manufacturing/concrete
         products) to a new corporation formed by Coleman S. Lyttle, a director
         of the Company and President of ETSW, for a total purchase price of
         $700,000, paid as follows: $350,000 cash at closing, assumption of
         $100,000 of indebtedness of ETSW and notes payable to ETSW in the
         aggregate amount of $250,000. Mr. Lyttle will continue to serve as a
         director of the Company and as President of ETSW after the purchase.

(19)     Management's Plans

         The Company experienced a substantial loss of $4,807,351 for the
         ten-month period ended March 31, 1998. Stockholders' deficit at March
         31, 1998 was $713,619 which represents a decrease of $3,683,142 from
         stockholders' equity of $2,969,523 at May 31, 1997. The Company's
         current liabilities of $7,734,434 exceeded its current assets of
         $4,665,184 by $3,069,250 at March 31, 1998. The Company has experienced
         negative cash flows from operations the past three years. See note 2
         for restricted cash of $600,000 relating to the China Steel contract.
         Also, see note 10 for additional information relating to "assets of
         business transferred under contractual arrangements" of $267,666,
         stated net of a valuation allowance of $858,000, to Q Enterprises. The
         conversion of these assets to cash is dependent on the future
         profitable operations of Q Enterprises. Management is negotiating with
         certain note holders to convert debt to preferred stock and to obtain a
         line of credit from a bank. Management believes it can return the
         Company to profitable operations in fiscal 1999. There can be no
         assurance that management's negotiations will be successful or the
         Company will have profitable operations in fiscal 1999.
