ITEM 1.  BUSINESS
 
OVERVIEW
 
    GTS Duratek provides waste  treatment solutions for radioactive,  hazardous,
mixed  and other wastes. The  Company's strategy is (i)  to provide the low cost
solution to process contaminated waste streams, (ii) to combine its  proprietary
technologies  and  technical  support  services  to  provide  full-service waste
treatment, and  (iii) to  team,  where appropriate,  with other  companies  with
complementary  expertise to advance GTS Duratek's treatment solutions within its
target markets  and  into  new markets.  The  Company's  vitrification,  thermal
desorption  and  ion exchange  technologies convert  waste  to stable  forms for
storage or disposal while  achieving significant volume reduction.  Accordingly,
the  Company believes  its customers  benefit from  significant cost  savings as
compared to other  commercially-available alternatives. To  implement its  waste
treatment  technologies  and  provide related  technical  support  services, the
Company has a staff of  highly skilled personnel with significant  environmental
services experience.
 
    The  Company's waste  treatment technologies  include vitrification, thermal
desorption and ion exchange and can be used independently or in tandem to  solve
the  waste  disposal  or  storage  problems  of  its  customers.  The  Company's
vitrification   technology   converts    waste   to   environmentally    stable,
leach-resistant  glass through a patented  high-temperature melter system, known
as a DuraMelter-TM-. The  thermal desorption and  ion exchange technologies  are
used by the Company to treat petrochemical and liquid radioactive waste streams,
respectively, and can be used to separate the waste streams into components that
can  either be safely stored, recycled or used as additives in the vitrification
of other waste streams. The Company's  ability to integrate its waste  treatment
technologies   enables  it  to  handle  a   diversity  of  waste  streams  in  a
cost-effective manner.
 
    The Company has over 450 engineers, consultants and technicians who  support
and  complement its waste treatment and stabilization services and also provides
highly specialized technical support services  for the Company's customers.  The
technical  support  services  provide a  consistent  source of  revenue  and the
complementary expertise  for  the Company  to  expand and  diversify  its  waste
treatment  technologies.  The services  provided  by the  Company  include staff
augmentation and  outage support,  principally to  assist nuclear  power  plants
during  regular maintenance shutdowns, environmental and computer consulting and
environmental safety training.  Having these technical  resources available  has
enabled the Company to move its technologies from bench-scale laboratory testing
to field operations and commercial application more rapidly and to handle larger
scope waste cleanup projects.
 
    The  Company  has  developed  the  following  important  joint  venture  and
collaborative arrangements  in order  to advance  the commercialization  of  its
waste treatment technologies and increase the number of markets that it serves:
 
    - THE  VITREOUS STATE  LABORATORY OF THE  CATHOLIC UNIVERSITY  OF AMERICA IN
      WASHINGTON, D.C.  ("VSL"). The  Company has  an established  research  and
      development relationship with the VSL, one of the leading research centers
      in the world for glass technology, including vitrification of waste.
 
    - CHEM-NUCLEAR  SYSTEMS,  INC.  ("Chem-Nuclear").  In  September  1994,  the
      Company established a joint venture with Chem-Nuclear, a subsidiary of WMX
      Technologies, Inc.,  to  jointly  pursue the  treatment  and  disposal  of
      commercial  low-level radioactive waste generated by nuclear power plants,
      hospitals, research  laboratories  and industrial  facilities.  The  joint
      venture   combines  the   Company's  DOE   vitrification  experience  with
      Chem-Nuclear's 22  years  of  experience in  providing  radioactive  waste
      services.
 
    - BNFL,  INC. ("BNFL").  In November  1995, the  Company formed  a strategic
      alliance with BNFL to jointly pursue up to five major DOE waste  treatment
      projects. BNFL is the U.S. subsidiary of British Nuclear Fuels plc, one of
      the largest processors of radioactive waste in the world.
 
                                       1
<PAGE>
    - THE  CARLYLE GROUP  ("Carlyle"). In  January 1995,  Carlyle, a Washington,
      D.C.-based private merchant  bank, made  a significant  investment in  the
      Company.  Carlyle provided the  Company with strong  financial support and
      experience with companies that contract with the federal government.
 
The Company seeks to utilize the complementary technical expertise or commercial
experience of the other parties  in these collaborative arrangements and,  where
possible,  to  develop  additional  collaborative  arrangements,  to  pursue its
primary markets and expand into new markets.
 
PROPRIETARY WASTE TREATMENT TECHNOLOGIES
 
    The Company has developed several waste treatment technologies for use on  a
variety  of radioactive, hazardous, mixed and other waste streams. The Company's
existing waste treatment technologies include vitrification, thermal  desorption
and  ion exchange and can be used independently  or in tandem to solve the waste
disposal or storage problems of its customers. The following is a brief  summary
of the Company's waste treatment technologies.
 
  VITRIFICATION
 
    GTS  Duratek's  vitrification  technology  involves  combining  radioactive,
hazardous, mixed  and  other  waste  with  glass-forming  additives  in  a  high
temperature  melter,  known as  a DuraMelter-TM-,  that reaches  temperatures of
1150 DEG.C to 1450 DEG.C (or 2100 DEG.F to 2640 DEG.F). The high temperatures of
the DuraMelter-TM- cause the  waste and any additives,  to form a molten  liquid
that  becomes  solid  glass  as  it  cools.  As  the  molten  liquid  cools, the
radioactive or  hazardous  atoms  become  chemically  bonded  in  the  molecular
structure  of the  glass for  long-term storage  or disposal,  thereby virtually
eliminating contamination of  the environment.  For certain  waste streams,  the
Company's vitrification technology can achieve volume reductions of up to 97%.
 
    The  DuraMelter-TM- is a proprietary melter system within a refractory-lined
cavity incorporating submerged electrodes which heat up the materials within the
cavity. Contaminated waste materials are deposited onto a melt surface in either
a liquid (slurry) or a solid  form. Glass forming additives are also  introduced
into  the  system  and  the  amount of  such  additives  is  dependent  upon the
characteristics of the  waste stream.  As the electrodes  in the  DuraMelter-TM-
raise  the temperature above  600 DEG.C, the waste  and additive mixture becomes
electrically conductive. Resistance  to the passage  of electricity through  the
mixture causes further heating and maintains the waste and additive mixture in a
molten  state. This process  is known as "joule  heating" and typically requires
temperatures of about  1150 DEG.C. Within  the DuraMelter-TM-, water  evaporates
and  organic substances  are oxidized forming  simple gases  which are channeled
into the  patented  off-gas  treatment  system.  The  inorganic  radioactive  or
hazardous  substances in the waste are  dissolved into the molten glass mixture.
The molten glass  exits through a  side opening  near the floor  of the  melting
cavity  and, depending upon  the characteristics of the  waste stream, is either
discharged in bulk  or directed  into the  proprietary GTS  Duratek gem  machine
where  it  forms into  beads,  1 to  2  centimeters in  diameter,  for long-term
storage. As  the beads  of molten  mixture cool,  the inorganic  radioactive  or
hazardous  substances become  chemically bonded  or "locked"  into the molecular
structure of the glass.
 
    DuraMelters-TM- range in size from small bench-scale units used for  testing
and  characterization of waste streams to  commercial sized melters designed for
large waste treatment and remediation projects. Currently, the Company's largest
commercial operating DuraMelters-TM- can process  up to approximately 400  cubic
feet  of  waste  per day.  The  design  of the  DuraMelter-TM-  can  be modified
depending upon  the characteristics  of the  waste stream  to be  processed.  To
process  waste streams that have  a higher content of  soil or sand, the Company
has  designed  a  DuraMelter-TM-  with  higher  temperature  capability  (up  to
1450  DEG.C or 2640 DEG.F). To process waste streams that include a high content
of corrosive  elements such  as  sulfates, phosphates,  lead and  nitrates,  the
Company  has designed a  DuraMelter-TM- with multiple  waste chambers to protect
the electrodes from the corrosiveness of the waste stream.

<PAGE>
  THERMAL DESORPTION TECHNOLOGY
 
    The Company's thermal desorption technology separates hazardous wastes  into
more  stable waste components that can either be safely stored, recycled or used
as additives in the processing of other  waste streams. The overall result is  a
reduction  in  the costs  of  treating and  disposing  of such  wastes.  In this
process, hydrocarbon sludges and  cakes are placed in  a thermal desorber  which
utilizes  temperatures in excess  of 635 DEG.C  (or 1175 DEG.F)  to separate the
waste into four components. The  components include solids which meet  universal
treatment  standards  land  disposal restrictions,  water  amenable  to low-cost
conventional waste  water treatment  or  deep well  disposal, reusable  oil  and
noncondensable gases. The Company's thermal desorption technology will initially
be  used at its DuraTherm facility in San Leon, Texas for the processing of high
solid content  petroleum refinery  and petrochemical  manufacturing wastes.  The
high  temperature  thermal  desorption  process is  protected  by  three patents
exclusively licensed by  the Company.  See "Business  -- Status  of Current  and
Potential Waste Treatment Projects -- DuraTherm Facility in San Leon, Texas."
 
  ION EXCHANGE
 
    The  Company  manufactures  and  supplies  highly  specialized  waste  water
purification   systems   and   patented    ion   exchange   media,   known    as
DURASIL-Registered   Trademark-,  for  commercial   nuclear  power  plants,  DOE
facilities and industrial clients.  DURASIL-Registered Trademark- is  formulated
to  separate specific  contaminants from  liquid waste  streams thereby allowing
radioactive and hazardous ions to be removed and separated into their respective
species.  Since  radioactive  and  hazardous  materials  are  regulated  by  two
different  government  agencies, this  ability to  separate mixed  waste greatly
simplifies  its  disposal.  DURASIL-Registered  Trademark-  also  has   physical
characteristics  that  enable  it  to  endure  extreme  waste  water  processing
conditions. It  is mechanically  stable  and nonflammable,  does not  shrink  or
swell,  is virtually immune to  radiation damage and has no  effect on the pH of
the waste stream. The Company has developed different
DURASIL-Registered   Trademark-   ion   exchange   media   depending   on    the
characteristics   of  the  liquid  waste  stream.  To  complement  its  line  of
DURASIL-Registered Trademark- ion exchange media, the Company also developed the
DURA C-TM-  line  of  activated  carbons  which  are  high  capacity,  specialty
filtration media designed for treatment of water containing mixed waste.
 
    The  Company  utilizes  its  proprietary  ion  exchange  technology  and its
abilities in designing and implementing  waste water treatment systems to  solve
the  liquid waste treatment and  disposal problems of its  customers. At the DOE
site in Fernald, Ohio, the Company studied liquid samples from waste streams and
conducted bench-scale evaluations of its DURASIL-Registered Trademark- and other
nonproprietary ion exchange  media in conjunction  with various other  treatment
methods.  After successful  completion of  the first  phase of  the project, the
Company was  awarded the  second phase  in which  it designed,  constructed  and
operated  a  demonstration unit  on site  at Fernald.  In addition,  the Company
designed, constructed  and operated  a waste  water treatment  system for  mixed
waste  for Martin Marrieta  Energy Systems, Inc.  at its Oak  Ridge Facility and
designed and  built three  waste  water cleanup  systems  for the  Taiwan  Power
Company's  Kuosheng  Nuclear  Power Plant.  In  February 1995,  the  Company was
awarded an $800,000 subcontract by WSRC to provide ion exchange water  treatment
services at the DOE's Savannah River site.
 
STATUS OF CURRENT AND POTENTIAL WASTE TREATMENT PROJECTS
 
    The Company has completed, is currently involved in or is bidding on several
vitrification  projects for the DOE through  subcontracts with DOE site managers
and  in   the  application   of  its   waste  treatment   technologies  to   the
commercially-generated  low-level radioactive waste and hazardous waste markets.
The following is a summary of the status of several of the Company's major waste
treatment projects.
 
  SAVANNAH RIVER M-AREA PROJECT
 
    The DOE's Savannah River site  near Aiken, South Carolina has  approximately
18.7  million cubic feet  in total currently stored  inventory and twenty years'
projected volume of low-level radioactive
 
                                       3
<PAGE>
and mixed wastes. This represents about 31% of all of such wastes throughout the
DOE weapons facilities. The Savannah River site is the largest single repository
of low-level radioactive and mixed wastes among all DOE sites.
 
    In November  1993,  the  Company  was awarded  a  subcontract  by  the  site
management  and operations  contractor, WSRC,  to vitrify  90,000 cubic  feet of
low-level mixed waste sludge stored in  the M-Area tanks at Savannah River.  GTS
Duratek's  subcontract represents only 0.5% of the total mixed waste inventoried
at Savannah  River.  The Company's  obligations  under this  subcontract  entail
vitrifying  the waste and performing ancillary  services related to the handling
of the waste,  including removal  of the  radioactive sludges  from the  storage
tanks,  cleanup and  decontamination of the  storage tanks and  placement of the
containers of the glass waste in a secure storage area. The project is  expected
to take approximately three years to complete.
 
    Construction  of the melter began in July  1995 and was completed on January
10, 1996. The Company designed and constructed the DuraMelter-TM- and will serve
as the operator. WSRC began an operational readiness assessment of the  facility
in  January  1996  which  will  allow the  Company  to  begin  operation  of the
DuraMelter-TM- upon completion of a short testing period using  non-radioactive,
simulated   waste   material.   The  M-Area   contract   represents   the  first
"privatization" type contract entered into by  the DOE for waste cleanup at  its
facilities.  Pursuant to  this contract,  the Company  will own  and operate the
DuraMelter-TM- under its subcontract  with WSRC. The  Company believes that  the
DOE  will enter  into more of  these privatization  arrangements with commercial
vendors and that the Company's contract  at Savannah River has been  extensively
used as a model for contemplated future privatized DOE waste cleanup projects.
 
  FERNALD MAWS PROJECT
 
    The  Company's first  vitrification project,  which began  in 1991,  was the
Minimum Additive  Waste  Stabilization ("MAWS")  project  at the  DOE's  Fernald
Environmental  Management Project near Cincinnati, Ohio under a subcontract with
Argonne  National  Laboratories.  The   MAWS  project  involved  the   Company's
demonstration of minimum additive waste vitrification, or blending waste streams
of  varying chemical and physical characteristics in a melter and exploiting the
natural glass-forming properties of each  component waste. The Company  believes
that the application of the MAWS concept to future waste treatment projects will
result in much lower operating costs and achieve significant volume reduction by
producing glass that is almost entirely composed of waste materials. GTS Duratek
designed,  constructed and  operated a DuraMelter-TM-  vitrification facility at
Fernald and  began processing  simulated  wastes in  September 1993  and  actual
Fernald mixed radioactive wastes in July 1994 in accordance with its subcontract
with Argonne National Laboratories. Through the MAWS project, the Company became
the  first in the country to process mixed waste at a DOE facility. Through MAWS
and an additional  related project,  the Company gained  extensive knowledge  of
waste  streams at the  DOE's facilities, which the  Company believes provides it
with a competitive advantage in procuring future subcontracts for DOE projects.
 
  FERNALD K-65 PROJECT
 
    In September 1994,  FERMCO awarded  the Company  a subcontract  to design  a
DuraMelter-TM- to vitrify the sludge in the K-65 silos at Fernald. The sludge in
the  K-65 silos contains substantial amounts of radon, lead, nickel, phosphates,
nitrates and sulfates.
 
    The initial K-65 subcontract called for the Company to provide a pilot-scale
melter and associated gem machine capable of processing up to three tons per day
of the K-65 silo waste. With GTS Duratek's assistance, FERMCO began assembly  of
the DuraMelter-TM- at Fernald in July 1995 and completed construction at the end
of  1995.  The Company  is advising  FERMCO during  construction tests  and will
provide consulting  support for  the startup  of the  melter. FERMCO,  the  site
environmental  restoration  management  contractor,  will  own  and  operate the
DuraMelter-TM-. Although the Company has substantially completed its obligations
under the initial subcontract for the pilot-scale melter, the unit will  process
only  a small fraction of  the radioactive waste contained  in the K-65 silos at
 
                                       4
<PAGE>
Fernald. FERMCO recently awarded  the Company a new  subcontract to develop  the
process  chemistry  for the  operation  of a  pilot-scale  vitrification system.
FERMCO plans  to  build  a vitrification  system  five  times the  size  of  the
pilot-scale  vitrification  system for  the cleanup  of the  K-65 waste  and has
issued an  expression  of interest  to  identify companies,  like  GTS  Duratek,
capable of designing and constructing such a vitrification system.
 
  HANFORD TANK WASTE REMEDIATION SYSTEM PROJECT
 
    The Hanford, Washington site is the single largest DOE facility and contains
the largest amount of high-level radioactive waste in the United States. Hanford
contains  approximately 61 million  gallons of high-level  radioactive waste and
spent nuclear fuel which is contained in 177 underground storage tanks. The  DOE
has  recently released a request  for proposals ("RFP") for  the cleanup of this
waste. According  to estimates  prepared  by the  DOE,  the cleanup  project  at
Hanford  could  take  at least  20  years and  cost  over $40  billion.  Under a
tri-party agreement among the DOE, the  EPA and the Washington State  Department
of Ecology, vitrification has been selected as the preferred method to stabilize
the contaminated wastes at Hanford.
 
    The  final RFP for Phase I of the project was released in February 1996 with
the DOE expected to award contracts for Phase I around August 1996. According to
the RFP, the first part of Phase  I involves a 16 month developmental period  to
establish  technical and operational elements  of the privatized facilities. The
second part of Phase I involves parallel vitrification test demonstrations  that
will  treat about 6% to 13% of the Hanford  tank waste by the year 2004. The RFP
indicates that the DOE will select at least two contractor teams to perform  the
Phase  I  vitrification  tests. Each  team  will be  responsible  for vitrifying
between one  and  two  million  gallons  of the  Hanford  waste  with  one  team
vitrifying  both high-level and low-level radioactive  wastes and the other team
storing high-level  radioactive  wastes  and  vitrifying  low-level  radioactive
wastes.  The Phase I portion of the project will conclude with a decontamination
and decommissioning of  the cleaned  tanks, followed  by RCRA  closure and  site
decontamination, all of which is expected to last an additional two years. Phase
II of the cleanup of the Hanford tank waste is not expected to start until 2004.
The  Company has  agreed to  jointly pursue the  Hanford project  with BNFL. See
"Joint Venture and Collaborative Arrangements -- BNFL."
 
  IDAHO ADVANCED MIXED WASTE TREATMENT PROJECT
 
    The Company and BNFL  have also recently agreed  to exclusively team on  the
DOE's  advanced mixed  waste treatment  project in  Idaho. The  DOE has recently
issued an RFP for  this project and  is expected to  award contracts by  October
1996.  The DOE is required, under an agreement with the State of Idaho, to begin
processing the mixed waste on  site by 2003 and to  have the waste removed  from
the  State of  Idaho by no  later than 2018.  There is an  estimated 2.3 million
cubic feet  of  inventoried and  non-inventoried  waste and  an  additional  1.4
million  cubic feet of contaminated soil that may require processing. This waste
is currently being stored in drums and crates in buildings and in earthen berms.
See "Joint Venture and Collaborative Arrangements -- BNFL."
 
  DURACHEM FACILITY IN BARNWELL, SOUTH CAROLINA
 
    As part  of  the  DuraChem  joint  venture,  the  Company  and  Chem-Nuclear
constructed   a  vitrification  facility  at  Chem-Nuclear's  radioactive  waste
processing center at Barnwell, South Carolina. During 1995, the Company designed
and constructed a new DuraMelter-TM- at the facility and will be responsible for
the vitrification operations.  The facility  was granted  its initial  operating
permit  in  November  1995. Chem-Nuclear  manages  the overall  facility  and is
responsible  for  procuring  all  required  operating  permits,  obtaining   the
low-level  radioactive waste from  its customers, transporting  the waste to the
facility and  removing  the  waste  for  ultimate  disposal  once  it  has  been
vitrified.  Through the DuraChem joint venture, GTS Duratek has become the first
company in  the  United  States  to  convert  commercially  generated  low-level
radioactive waste to glass. See "Joint Venture and Collaborative Arrangements --
DuraChem."
 
    DuraChem's  Barnwell facility  will process contaminated  filtration and ion
exchange resins from nuclear power plants and contaminated wastes from hospitals
and laboratories. In initial test runs on
 
                                       5
<PAGE>
contaminated nuclear power plant resins, the DuraMelter-TM- achieved significant
waste volume reductions  of up to  97%. On  other types of  wastes, the  Company
believes that it will be able to achieve volume reductions of 93% or better. The
DuraChem  facility is located adjacent to the  Barnwell landfill, one of the few
facilities in  the  United  States permitted  to  accept  commercially-generated
low-level  radioactive waste. Over  the last 15 years,  no new radioactive waste
storage sites have  been built  or licensed in  the United  States. The  Company
believes  that DuraChem's location  is advantageous because  of its proximity to
the nation's primary facility for handling low-level radioactive waste.
 
  DURATHERM FACILITY IN SAN LEON, TEXAS
 
    The Company acquired an 80% interest  in BEGCI, since renamed DuraTherm,  on
November  30,  1995.  DuraTherm  is  a  RCRA  Part  B-permitted  hazardous waste
recycling center  located in  San  Leon, Texas  which  uses a  patented  thermal
desorption  technology to treat and  produce recyclable materials from hazardous
oil refinery  and petrochemical  plant sludges.  The Company  purchased the  80%
interest  for one dollar from  a subsidiary of Bird  Corporation and agreed with
the remaining stockholders to invest up to $5.1 million for capital improvements
and working capital for the facility. The 20% minority interest is owned by  the
operators  of  the  DuraTherm  facility,  each  of  which  has  entered  into an
employment agreement providing for incentive  compensation tied directly to  the
financial  performance of  the facility.  Operations at  the facility  have been
suspended until completion of the  capital improvements. The Company expects  to
complete the capital improvements and resume operations in the second quarter of
1996.
 
    DuraTherm  has a patented  thermal desorption process  that removes volatile
gases and recovers oil from contaminated sludges generated by oil refineries and
processing operations. The oil recovered can be recycled. The thermal desorption
process is effective on sludges  with a Btu content  of between 2,000 and  5,000
per  ton. Most  incinerators and  cement kilns,  alternative processing methods,
typically cannot  cost-effectively handle  sludges with  Btu levels  within  the
effective  range  for the  thermal  desorption process.  The  DuraTherm facility
provides the Company a permitted site to demonstrate and use other  technologies
including vitrification and ion exchange.
 
JOINT VENTURE AND COLLABORATIVE ARRANGEMENTS
 
    In  order  to commercialize  its vitrification  technology more  rapidly and
cost-effectively, the Company has developed several important joint venture  and
collaborative  arrangements.  The following  is a  summary  of certain  of these
relationships.
 
  VSL
 
    The Company has established a research and development relationship with the
VSL of The  Catholic University in  Washington, D.C. pursuant  to which the  VSL
provides ongoing research and development capabilities and technical services in
support   of  the  Company's  waste  cleanup  projects.  In  this  complementary
relationship, the  VSL  provides  the  necessary  technology  and  research  and
development  support  while the  Company advances  the technology  to commercial
application.
 
    The VSL, a research facility with a  staff of 90 researchers, is one of  the
leading   research  centers  in  the   world  for  glass  technology,  including
vitrification.  The  laboratories   at  the   VSL  are   equipped  with   highly
sophisticated  analytical  tools  which  enable  the  researchers  to  perform a
comprehensive array of analyses. The VSL's research and development capabilities
include waste characterization, testing  of radioactive waste-loaded glasses  to
evaluate  glass durability,  processability and  leachability, glass dissolution
computer modeling,  batch  melting and  the  study  of ion  exchange  media  for
removing specific contaminants from liquid waste streams. Various DuraMelter-TM-
models have been designed and constructed at the VSL for use by the staff of the
VSL  in its  research and  analytical work. In  addition, the  facility is fully
licensed for radioactive  and hazardous materials  research. The VSL  is led  by
Pedro B. Macedo, Ph.D. and Theodore A. Litovitz, Ph.D. who are the inventors and
owners  of the technology  licensed exclusively to the  Company for ion exchange
and the vitrification  of radioactive,  hazardous, mixed and  other wastes.  See
"Business -- Patents and Other Intellectual Property Rights."
 
                                       6
<PAGE>
    In  addition to being  the source of the  vitrification technologies used by
the Company, the VSL provides ongoing services to the Company in support of  its
waste  treatment projects. The  VSL conducts expert  waste composition and glass
treatability studies before  any project  is commenced, assists  in the  initial
test  melt phase of each  project and works with  the Company's engineers in the
design  adaptation  of   the  DuraMelter-TM-   technology  to   fit  the   waste
characteristics  of  each new  cleanup project.  In  addition, the  VSL conducts
ongoing research and development into improvements on the existing vitrification
technologies and into entirely new  vitrification techniques, serving in  effect
as the research and development arm of the Company. The primary advantage to the
Company   from  its  relationship  with  the   VSL  is  the  access  to  leading
vitrification technologies and ongoing vitrification research without having  to
incur the ongoing overhead and administrative expenses if such capabilities were
in house.
 
    In  return,  the  Company  provides  ongoing  project  funding  for research
conducted at the VSL on behalf of the Company. During 1994 and 1995, the Company
paid $1.9  million  and  $789,000, respectively,  in  research  and  development
funding  to  the VSL.  For Company  waste  cleanup projects  in which  the VSL's
technical services are utilized by  the Company, the Company  pays the VSL on  a
time  and expense basis and includes the estimated cost for such services in its
formal bid proposal.  The VSL  is a not-for-profit  institution so  it does  not
include extra fees or percentage profits in its cost estimates.
 
  BNFL
 
    On  November 7, 1995, the Company and BNFL entered into a strategic alliance
agreement. BNFL is the  U.S. subsidiary of British  Nuclear Fuels plc, a  United
Kingdom-based   company  with  annual  revenues   of  approximately  $2  billion
worldwide. British  Nuclear  Fuels plc  is  one  of the  largest  processors  of
radioactive  waste in the world and is  one of only two companies worldwide with
commercial experience  in  processing  and  stabilizing  high-level  radioactive
wastes.  The strategic  alliance with BNFL  enhances the  Company's prospects of
obtaining major DOE waste treatment projects such as Hanford and Idaho and opens
opportunities for  international expansion.  BNFL has  been active  in the  U.S.
radioactive  waste market for the past five years, including being selected as a
member of the team to  manage the DOE's nuclear  waste facility in Rocky  Flats,
Colorado.
 
    Under  the terms of the strategic alliance, the Company and BNFL have agreed
to jointly pursue up to five major DOE waste treatment projects, with the  first
project  being the separation and  vitrification of high-level radioactive waste
at the DOE's Hanford, Washington facility.  The terms of the strategic  alliance
provide  that BNFL pays to the  Company a fee of $1.0  million each time the two
companies agree  to  exclusively pursue  a  waste treatment  project.  Upon  the
execution  of the  strategic alliance agreement,  the Company  received the $1.0
million fee for  its agreement to  pursue the Hanford  project exclusively  with
BNFL.  See "Business -- Status of Current and Potential Waste Treatment Projects
- -- Hanford Tank Waste Remediation System Project," and "-- Idaho Advanced  Mixed
Waste Treatment Project."
 
    As  part  of the  strategic  alliance, BNFL  invested  $10.0 million  in the
Company in the form of a  convertible debenture. The debenture accrues  non-cash
interest  during the first  five years at the  one-year London Interbank Offered
Rate (LIBOR) and is convertible at the  option of BNFL into 1,381,575 shares  of
the Common Stock prior to November 7, 2000. If the debenture is not converted or
extended, the Company must repay principal and interest in installments over the
five  year period beginning on November 8, 2000. BNFL also agreed to provide the
Company with research and development funding of at least $500,000 per year over
the next five years. The two parties will mutually agree on how the research and
development funding will be spent, but the Company will retain the rights to the
vitrification processes that it develops  through this funding. The Company  has
agreed  as part  of the strategic  alliance to sublicense  its radioactive waste
vitrification technologies to BNFL for use only in the United Kingdom.
 
  DURACHEM
 
    In September 1994, the Company formed  a joint venture with Chem-Nuclear  to
design,  construct and  operate vitrification  facilities to  process commercial
radioactive waste for disposal, including low-
 
                                       7
<PAGE>
level  radioactive  wastes  from  nuclear  power  plants,  hospitals,   research
laboratories  and  industrial  facilities.  The  joint  venture  entity,  called
DuraChem, is 55% owned by Chem-Nuclear and 45% by the Company. The joint venture
represents the combination of the Company's proprietary vitrification technology
and Chem-Nuclear's  22  years  of  experience  in  providing  radioactive  waste
handling and processing services. DuraChem will first pursue the disposal market
for  ion exchange resins which are generated  by nuclear power plants. The first
vitrification facility of this joint venture is located at Chem-Nuclear's  waste
processing  center  at  Barnwell,  South Carolina.  The  need  for  the services
provided by  DuraChem  was  created  by the  closure  of  nationally  accessible
low-level  radioactive waste disposal  sites and the delay  by state compacts in
opening new  regional  sites.  The  scarcity of  disposal  capacity  has  forced
commercial  generators of  low-level radioactive waste  to store  their waste at
their facilities until  regional sites are  opened. See "Business  -- Status  of
Current and Potential Waste Treatment Projects -- DuraChem Facility in Barnwell,
South Carolina."
 
  VITRITEK
 
    Through  a joint venture with  Vitritek Holdings Company, L.L.C., ("Vitritek
Holdings") a privately-held entity, the  Company has extended its  vitrification
technology to non-radioactive wastes. The joint venture entity, called Vitritek,
is  50% owned by each  of the Company and  Vitritek Holdings. The joint venture,
formed in December 1993, represents the consolidation of co-licensing rights  to
non-radioactive  vitrification technologies  previously acquired  by the Company
and Vitritek Holdings.  Under the terms  of the joint  venture arrangement,  all
funding requirements and all profits are shared equally.
 
    In  November 1994, Vitritek,  along with the  VSL, completed a demonstration
project for the White House in Washington, D.C. converting approximately one ton
of asbestos-laden construction  debris from the  White House renovation  project
into  recyclable  glass.  Vitritek was  awarded  its  first, and  only  to date,
commercial subcontract  in  September 1994  by  WSRC to  conduct  a  comparative
vitrification study on asbestos materials at the Savannah River site in order to
determine  which of two melting technologies is better suited for converting the
Savannah River asbestos to glass. In  the study, the Company conducted  parallel
tests  using joule-heated  and plasma-arc furnaces  to vitrify about  25 tons of
asbestos-laden waste material.
 
TECHNICAL SUPPORT SERVICES
 
    The Company has  over 450  engineers, consultants and  technicians, some  of
whom  are full-time  employees and the  balance of whom  are contract employees.
These employees support  and complement the  Company's waste treatment  services
and also provide highly specialized technical support services for the Company's
customers.  This  business  provides  a consistent  source  of  revenue  and the
necessary complementary expertise for  the Company to  expand and diversify  its
waste  treatment  technologies  business  in the  future.  The  primary services
provided  by  the  Company  include  staff  augmentation  and  outage   support,
principally to assist nuclear power plants during regular maintenance shutdowns,
environmental  and computer  consulting, and environmental  safety training. The
Company provides these technical services either  as a prime contractor or as  a
subcontractor  to a  diverse group  of government  agencies, electric utilities,
industrial facilities and  commercial businesses including  the DOE, Duke  Power
Company, New York Power Authority, UNISYS Corporation and WSRC.
 
  STAFF AUGMENTATION AND OUTAGE SUPPORT SERVICES
 
    The  Company  provides  trained  personnel to  assist  nuclear  power plants
undergoing   periodic   refueling,   maintenance   outages,   construction    or
decommissioning.  There are  119 nuclear  power generating  units in  the United
States, of which 108 are operational. To control costs, utilities maintain their
permanent staffs at  the level  needed for steady-state  power operations.  They
supplement  their full-time staffs during refueling and maintenance outages with
skilled contract personnel. Every 12 to 24 months, nuclear power plants are shut
down for scheduled maintenance that typically takes 30 to 90 days. This shutdown
and maintenance operation costs the nuclear power facility on average $1 million
for every day it  is closed. Accordingly, there  is a strong economic  incentive
for  the nuclear power facilities to  hire trained and experienced personnel for
these maintenance operations in order
 
                                       8
<PAGE>
to complete the servicing as quickly and efficiently as possible. The  Company's
trained  technicians and personnel are  experienced in outage support procedures
and are effective at helping to minimize the cost of the power facilities'  down
time.
 
    The  offering  of services  for operating  nuclear  power plants  provides a
considerable market for the  Company, despite the fact  that no new plants  have
been  ordered in over  10 years. The  demand for the  Company's services results
from the  extensive  overhaul required  to  extend  the life  of  aging  plants,
replacement of major components of existing plants, startup of plants recovering
from  long-term shutdown,  modifications to  the plants  resulting from changing
legislation and the decommissioning of plants that have reached the end of their
useful lives.
 
    The Company's largest customer for staff augmentation services is Duke Power
Company, which accounted for approximately  23% of the Company's total  revenues
in  1994 and 1995. Duke  Power currently has seven  nuclear power units at three
sites. Under a  series of  contracts between the  Company and  Duke Power  which
expire between 1997 and 1998, the Company provides a group of technicians to the
Duke  Power system  year-round and provides  additional personnel  to Duke Power
during planned maintenance outages. Other  nuclear power utilities to which  the
Company provides augmentation and outage support services include New York Power
Authority, Tennessee Valley Authority, PECO Energy, Vermont Yankee Power Company
and Southern Nuclear Operating Company.
 
  ENVIRONMENTAL AND COMPUTER CONSULTING SERVICES
 
    The  Company provides extensive environmental consulting services to clients
in  the   areas   of  environmental   remediation,   facility   decommissioning,
Occupational  Safety and  Health Act  ("OSHA") and  EPA compliance  audits, site
characterization, licensing and permitting and air quality and emission studies.
The Company either supplies professionals and technical personnel to  supplement
client  staffs or assumes responsibility for entire projects. Included among the
Company's available  personnel for  such environmental  consulting projects  are
chemical,  civil  and  environmental  engineers,  certified  health  physicists,
chemists,  toxicologists,  safety  and  health  experts,  regulatory  compliance
specialists,  remediation experts,  radiological control  technicians, hazardous
material technicians,  decontamination  experts  and others.  The  Company  also
supplies  professionals and technical specialists in a wide range of scientific,
engineering, data processing and  communications disciplines. These  individuals
perform  computer consulting  services such as  program assessment/ development,
computer  software  development,   quality  assurance  audits,   non-destructive
examination  and computer training for a broad base of clients. In January 1996,
GTS  Duratek  acquired  Analytical   Resources,  Inc.,  a  small   environmental
consulting  firm that  has been  involved in  many DOE  consulting projects. The
Company's management believes  that this acquisition  adds senior  environmental
management and consulting resources to the Company.
 
  ENVIRONMENTAL SAFETY TRAINING
 
    The  Company  provides  radiation protection  and  hazardous  waste training
services nationwide. During  1995, the Company's  training specialists  prepared
candidates,  consisting  of health  physics  technicians and  professionals from
nuclear power plants, universities and laboratories nationwide, for the National
Registry of  Radiation Protection  Technologists and  American Board  of  Health
Physics  certification  examinations.  The  Company's  training  programs enable
customers to  realize  cost  savings through  increased  worker  competence  and
productivity,  enhanced workplace safety and improved compliance with regulatory
requirements.
 
CUSTOMERS
 
    The Company  derives  revenues  related  to  its  proprietary  vitrification
technologies   principally  through  subcontracts  with  a  combination  of  DOE
contractors and subcontractors including WSRC and FERMCO. Revenues derived  from
DOE-related  subcontracts  represented 22.7%  and 35.0%  of the  Company's total
revenues during  1994 and  1995, respectively.  The Company  provides  technical
support  services to a diverse group  of government agencies, including the DOE,
the  DOD,  the  EPA  and  state  environmental  protection  agencies,   electric
utilities, including Duke Power Company, New York
 
                                       9
<PAGE>
Power  Authority,  Tennessee  Valley  Authority,  Vermont  Yankee  Nuclear Power
Corporation, PECO Energy and Southern Nuclear Operating Company, and  industrial
facilities  and  commercial businesses,  including UNISYS  Corporation. Revenues
from Duke Power, WSRC and FERMCO  accounted for approximately, 22.6%, 17.4%  and
16.1%,  respectively,  of  the  Company's revenues  for  1995.  The  Company has
multiple contracts  with Duke  Power  which expire  between  1997 and  1998  and
pursuant to which it provides technical support services and personnel.
 
SALES AND MARKETING STRATEGY
 
    The  Company's operations to date have  provided it with extensive knowledge
of DOE and  other waste stream  composition and the  factors that influence  the
remediation  of those waste streams. The Company's internal sales force uses and
will continue to use that knowledge  and operating experience to strengthen  the
Company's  competitive position  when pursuing  DOE and  other waste remediation
projects. In addition, through its collaborative arrangements, the Company  will
seek  to  utilize  complementary technical  expertise,  marketing  resources and
commercial experience of the other parties to develop additional business in its
primary markets,  expand its  capabilities in  handling a  greater diversity  of
waste streams and replicate its operating model to pursue international markets.
The Company pursues markets where it can be the most cost-effective processor of
the  waste due to its technologies, geographical  proximity to a waste stream or
government regulation.
 
    In its  technical  support  services  business, GTS  Duratek  will  seek  to
strengthen  its relationships  with its  large utility  customers, such  as Duke
Power Company, Tennessee  Valley Authority,  PECO Energy  Services and  Southern
Nuclear  Operating Company, which are  significant contributors to the Company's
total revenues.  For its  consulting and  staff business,  the Company  is  also
pursuing  arrangements in  which single-nuclear-unit  utilities can  form users'
alliances  with  the  Company  as  the  sole  staff  support  contractor.  These
arrangements    would    emulate   the    Company's   contracts    with   large,
multiple-nuclear-plant utilities.  The Company  is also  pursuing  opportunities
with  utilities that are downsizing and outsourcing  service work as well as DOE
sites that  are  privatizing  departments  such  as  training  and  radiological
controls. To enhance the overall profitability of the technical support services
business,  the Company is  focusing on increasing  market share in environmental
and computer consulting, radiation instrument services and environmental  safety
training,  all of  which generate  relatively higher  profit margins  than staff
augmentation and outage support.
 
ENVIRONMENTAL MATTERS
 
 ENVIRONMENTAL LAWS AND REGULATIONS CREATING A DEMAND FOR THE COMPANY'S WASTE
 TREATMENT TECHNOLOGIES
 
    Various environmental protection laws have  been enacted and amended  during
recent  decades  in  response  to  public  concern  over  the  environment.  The
operations of the Company's customers are subject to these evolving laws and the
implementing regulations. The  Company believes that  the obligations to  comply
with  the requirements of  the following laws  contribute to the  demand for its
services:
 
    The AEA and the Energy Reorganization Act of 1974 (the "ERA") authorize  the
NRC  to  regulate  the  receipt, possession,  use  and  transfer  of radioactive
materials,  including  "source  material,"   "special  nuclear  material,"   and
"byproduct  material."  Pursuant to  its authority  under the  AEA, the  NRC has
adopted regulations  that  address  the management  and  disposal  of  low-level
radioactive  waste  and  that  require  the  licensing  of  commercial low-level
radioactive waste disposal sites.
 
    The storage and  disposal of  high-level nuclear  waste are  subject to  the
requirements  of the Nuclear Waste  Policy Act, as amended  by the Nuclear Waste
Policy Act  Amendments.  These  statutes regulate  the  disposal  of  high-level
nuclear  waste  by establishing  procedures  and schedules  for  siting geologic
repositories for  such  waste.  The  statutes  also  direct  EPA  to  promulgate
environmental  standards  for  the  disposal of  high-level  nuclear  waste, and
require the  NRC  to  promulgate  standards  covering  the  licensing  of  waste
repositories.  The  NRC  has issued  regulations  that address  the  storage and
disposal of high-level nuclear waste.
 
                                       10
<PAGE>
    The Uranium Mill Tailings Radiation  Control Act ("UMTRCA") and the  Uranium
Mill  Tailings Remedial  Action Amendments  Act are  intended to  protect public
health and  the environment  from hazards  associated with  uranium ore  milling
wastes at active and inactive uranium mills. UMTRCA designates specific inactive
mill  sites  for  remedial action,  and  gives  the DOE  the  responsibility for
carrying out remedial actions at these sites.
 
    The locations  for future  low-level radioactive  waste disposal  facilities
also  may be  affected by  the Low-Level  Radioactive Waste  Policy Act  of 1980
("LLRWPA") and the  Low-Level Radioactive Waste  Policy Amendments Act  ("LLRWPA
Amendments"). The LLRWPA addresses the siting of new low-level radioactive waste
disposal facilities and establishes that each state is responsible for providing
disposal  capacity  for most  low-level  commercial radioactive  waste generated
within its borders. The statute also  encourages groups of states to enter  into
compacts  providing for the  development and operation  of low-level radioactive
waste disposal facilities. Incentives for the formation of interstate  compacts,
and  the deadlines and procedures which states must meet in designating disposal
facilities were modified by the LLRWPA  Amendments. At the present time, no  new
radioactive  waste disposal  facilities have been  opened by  state compacts and
none are expected to open in the near future.
 
    RCRA  provides  a  comprehensive  framework   for  the  regulation  of   the
generation,  transportation, treatment, storage and disposal of hazardous waste.
The intent  of RCRA  is  to control  hazardous wastes  from  the time  they  are
generated  until  they  are  properly recycled  or  treated  and  disposed. RCRA
prohibits improper  hazardous  waste disposal  and  imposes criminal  and  civil
liability  for  failure  to comply  with  its requirements.  RCRA  requires that
hazardous waste  generators,  transporters  and  operators  of  hazardous  waste
treatment,  storage  and  disposal  facilities  meet  strict  standards  set  by
government agencies. In certain circumstances,  RCRA also requires operators  of
treatment,  storage  and  disposal facilities  to  obtain and  comply  with RCRA
permits. The Land Disposal Restrictions developed under the Hazardous and  Solid
Waste Amendments of 1984 prohibit land disposal of specified wastes unless these
wastes  meet  or  are treated  to  meet Best  Demonstrated  Available Technology
("BDAT") treatment standards, unless certain exemptions apply.
 
    TSCA provides EPA with  the authority to  regulate over 60,000  commercially
produced   chemical   substances.   EPA   may   impose   requirements  involving
manufacturing, record  keeping, reporting,  importing and  exporting. TSCA  also
established  a comprehensive regulatory  program for PCBs  which is analogous to
the RCRA program for hazardous waste.
 
    The Clean  Water  Act  establishes standards,  permits  and  procedures  for
controlling the discharge of pollutants from industrial and municipal wastewater
sources.
 
    The  Clean Air Act of  1970, as amended (the  "Clean Air Act"), empowers the
EPA to  establish  and enforce  ambient  air  quality standards  and  limits  of
emissions of pollutants from facilities. This has resulted in tight control over
emissions from technologies like incineration.
 
    The  Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended ("CERCLA" or "Superfund"), and subsequent amendments under  the
Superfund   Amendments  and  Reauthorization   Act  ("SARA")  impose  continuing
liability upon generators of hazardous substances (among other parties) and such
potential liability may significantly  affect a generator's  decision on how  to
dispose  of the wastes. The Community  Right-to-Know mandate established by SARA
requires full  disclosure  of  all  environmental releases  to  the  public  and
contributes  to public awareness and  activism regarding corporate environmental
management issues. To the  extent a generator's waste  can be reported as  being
recycled,   potential  liability  and  public  pressure  can  be  eliminated  or
significantly reduced.
 
    CERCLA and SARA, as  implemented by the  National Contingency Plan,  provide
for  the investigation and remediation of sites containing hazardous substances.
The  Superfund  program's  regulations  require  that  any  remediation  of  the
hazardous  substances meet applicable and relevant and/or appropriate regulatory
requirements. Superfund's  remedy selection  process includes  a preference  for

innovative  technology. Superfund also establishes  strict liability for parties
who generated  or transported  hazardous substances  or owned  and operated  the
sites containing them. This may create a strong incentive to avoid on-site waste
treatment  in favor of utilizing technologies like the Company's waste treatment
technologies, which can, in certain instances, effectively recycle wastes.
 
    The Pollution Prevention Act of  1990 establishes pollution prevention as  a
national  objective, naming it a primary  goal wherever feasible. The Act states
that if  pollution cannot  be  prevented, materials  should  be recycled  in  an
environmentally safe manner.
 
    Under  the mandate of the Federal  Facility Compliance Act ("FFCA"), the DOE
is currently  engaged in  a program  to treat  and dispose  of the  mixed  waste
currently  stored at its facilities. The FFCA required DOE to develop and comply
with treatment and  disposal plans for  each of its  facilities and charges  DOE
with  developing treatment and disposal capacity  for these wastes where it does
not currently exist. The plans must also  address the need to treat and  dispose
of mixed wastes generated from the remediation of contaminated DOE sites.
 
 ENVIRONMENTAL LAWS AND REGULATIONS AFFECTING THE USE OF THE COMPANY'S WASTE
 TREATMENT TECHNOLOGIES
 
    Pursuant to the mandate of the AEA and the ERA, NRC regulations and guidance
address  the classification and  management of low-level  radioactive waste. The
NRC regulations also govern the technical, monitoring and safety-related aspects
of developing  and operating  low-level radioactive  waste disposal  facilities.
Pursuant  to its authority under the AEA, the NRC also has established licensing
requirements and operating procedures for such facilities. The NRC  requirements
address  siting criteria, site stability,  the development and implementation of
institutional  controls   for   the   facility   (e.g.,   access   restrictions,
environmental monitoring and site maintenance), facility operation, closure, and
site stabilization.
 
    Under  RCRA, wastes are classified as  hazardous either by specific listings
or  because  they  display  certain  hazardous  characteristics.  Under  current
regulations,  waste residues derived from  listed hazardous wastes are generally
considered to be  hazardous wastes  unless they  are delisted  through a  formal
rulemaking process that may last a few months to several years. For this reason,
waste  residue that is generated by the treatment of listed hazardous wastes but
which has  no  beneficial  use,  including  waste  treated  with  the  Company's
vitrification  technologies, may be considered  a hazardous waste without regard
to the fact that  this waste residue may  be environmentally benign.  Subsequent
management  of  such waste  residue would  be subject  to full  RCRA regulation,
including the prohibition against land disposal without treatment in  compliance
with  BDAT. The RCRA regulation classifying  such waste residue as hazardous has
been overturned  by the  District of  Columbia Court  of Appeals,  but has  been
temporarily  reinstated until  the EPA  develops a  revised regulatory approach.
Under EPA's proposed  Hazardous Waste Identification  Rule, listed wastes  would
leave  the hazardous waste regulatory system if they met specified concentration
limits for  hazardous constituents.  The Company's  ownership and  operation  of
vitrification  facilities also  exposes the  Company to  potential liability for
cleanup of releases of hazardous wastes under RCRA.
 
    If the Company  engages in  the transportation of  radioactive materials  it
will  be subject to  the requirements of  the Hazardous Materials Transportation
Act, as amended by  the Hazardous Materials  Transportation Uniform Safety  Act.
Pursuant  to  these statutes,  the  United States  Department  of Transportation
regulates the  transportation  of  hazardous  materials,  including  radioactive
materials,  in  commerce. Shippers  and carriers  of radioactive  materials must
comply with both the general requirements for hazardous materials transportation
and with specific requirements for the transportation of radioactive  materials.
If  the Company engages in the storage  and disposal of high-level nuclear waste
it may be subject  to the Nuclear  Waste Policy Act, as  amended by the  Nuclear
Waste Policy Act Amendments.
 
    CERCLA  effectively imposes strict, joint  and several liability upon owners
or operators of facilities where a release of hazardous substances has occurred,
upon parties  who generated  hazardous  substances that  were released  at  such
facilities    and   upon   parties   who   arranged   for   the   transportation
 
                                       12
<PAGE>
of  hazardous  substances  to  such  facilities.  The  Company's  ownership  and
operation  of vitrification facilities  on-site expose the  Company to potential
liability under CERCLA for releases of hazardous substances into the environment
at those  sites. In  the  event that  off-site  storage or  disposal  facilities
utilized  by  the  Company for  final  disposition  of the  glass  and resulting
residues from the Company's vitrification process are targeted for investigation
and cleanup under CERCLA,  the Company could incur  liability as a generator  of
such  materials or  by virtue  of having  arranged for  their transportation and
disposal. The Company designs its DuraMelters-TM- to minimize the potential  for
release  of hazardous substances into the  environment. In addition, the Company
has developed plans to manage and minimize the risk of CERCLA or RCRA liability,
including the training of operators, use of operational controls and structuring
of its relationships  with the entities  responsible for the  handling of  waste
materials and by-products.
 
    The  Clean Air Act imposes strict  requirements upon owners and operators of
facilities which discharge pollutants into the environment. Although the Company
believes  that  its  proprietary  off-gas  treatment  system  effectively  traps
particulates  and  prevents hazardous  emissions  from being  released  into the
environment, which releases would violate the  Clean Air Act, the Clean Air  Act
may  require a permit prior  to the construction and  operation of the Company's
facilities and may require additional controls.
 
    The Clean  Water  Act  establishes standards,  permits  and  procedures  for
controlling the discharge of pollutants from industrial and municipal wastewater
sources. The Company believes that DuraMelters-TM- generally will not be subject
to  the  water pollution  control requirements  of the  Clean Water  Act because
DuraMelters-TM- are designed to have no residual wastewater discharge.  However,
the   Clean  Water  Act's  standards  permits  and  procedures  are  potentially
applicable to wastewater treatment  systems designed by  the Company, using  its
ion exchange technology.
 
    OSHA  provides for the establishment of standards governing workplace safety
and health  requirements,  including  setting permissible  exposure  levels  for
hazardous  chemicals  which  may be  present  in  mixed wastes.  The  Company is
required to follow OSHA standards, including the preparation of material  safety
data  sheets, hazardous response training and process safety management. The NRC
has set regulatory standards for exposure to radioactive materials.
 
    To the extent that the Company is  engaged in the processing or disposal  of
mixed  waste,  the radioactive  components are  subject  to the  NRC regulations
promulgated under  the AEA,  while the  hazardous components  of the  waste  are
regulated by the EPA under RCRA.
 
    Company  facilities  may  have  to  obtain  permits  under  state  laws that
correspond to the Clean Water Act and the Clean Air Act. The necessity to obtain
such permits depends  upon the  facility's location and  the expected  emissions
from the facility. Additional state licenses or approvals may also be required.
 
    Operators  of hazardous waste treatment, storage and disposal facilities are
required to obtain RCRA Part-B permits from the EPA or from states authorized to
implement the  RCRA program.  Obtaining such  permits is  a lengthy  and  costly
process that requires regulatory inspection and approval of, among other things,
the   facility  design,  equipment  and   operating  plans  and  procedures.  In
addition, applicants for  a RCRA  permit for  a treatment,  storage or  disposal
facility  must submit detailed  information regarding all  past waste management
practices at that facility  and may be required  to undertake corrective  action
for  past contamination  of the  site. The  Company's DuraTherm  facility in San
Leon, Texas  is a  RCRA Part-B  permitted facility.  The Company  has  developed
procedures  to ensure  compliance with RCRA  permit provisions  at the DuraTherm
facility, including  procedures for  ensuring appropriate  waste acceptance  and
scheduling, waste tracking, manifesting and reporting, and employee training.
 
COMPETITION
 
    The  market for the Company's  waste treatment technologies is characterized
as the treatment and stabilization of certain radioactive, hazardous, mixed  and
other wastes. The Company is aware of
 
                                       13
<PAGE>
some  competition from several large companies and numerous small companies. Any
of such companies may possess or  develop technologies superior to those of  the
Company.  While the Company is aware  of competition from companies with similar
waste treatment technologies, the primary competition comes from companies which
provide waste treatment and disposal  services. The predominant waste  treatment
and   disposal  methods   include  landfilling,   deep-well  injection,  on-site
containment and incineration or other thermal treatment methods. Competition  is
based   primarily  on  cost,  regulatory   and  permit  restrictions,  technical
performance, dependability  and environmental  integrity. The  Company  believes
that  it will be  able to compete favorably  on the basis  of these factors. The
Company also  believes  that it  has  several competitive  advantages  over  its
competitors  including  its proprietary  vitrification  technologies, integrated
approach to waste treatment, demonstrated commercial success of its technologies
and strategic alliances.  Many of the  Company's competitors have  substantially
greater  financial and technical resources than the  Company and there can be no
assurance that one or more of the  Company's competitors do not possess or  will
not  develop  waste treatment  technologies that  are superior  to those  of the
Company.
 
    In its  technical support  services, the  Company's competitors  range  from
major  national and  regional environmental  service and  consulting firms which
have large environmental remediation  staffs to small local  firms. Many of  the
major  national  and regional  environmental service  and consulting  firms have
greater financial,  management and  marketing resources  than the  Company.  The
availability  of skilled  technical personnel,  quality of  performance, safety,
diversity of services and price are the key competitive factors.
 
RESEARCH AND DEVELOPMENT ACTIVITIES
 
    The Company's research and development activities are conducted primarily by
the VSL for  the enhancement  of the  Company's existing  vitrification and  ion
exchange  technologies or  the introduction  of new  vitrification technologies.
During 1995, 1994 and 1993,  research and development activities were  conducted
at  the VSL  under contracts totaling  $789,000, $1.9 million  and $1.3 million,
respectively. The Company did not incur any additional research and  development
costs  during  those  years. In  connection  with various  Company  contracts or
subcontracts, the VSL  conducts research and  development under fixed-price  and
cost-plus-fixed fee contracts. Under these contracts, the research is supervised
by Drs. Macedo and Litovitz and all inventions and discoveries are owned by them
and  licensed to the Company under  the exclusive license agreement. The Company
expects to spend a significant portion  of the research and development  funding
provided  by BNFL with the VSL. See "Business -- Joint Venture and Collaborative
Arrangements -- VSL" and "-- BNFL."
 
PATENTS AND OTHER INTELLECTUAL PROPERTY RIGHTS
 
    The Company  licenses all  of  the patent  and other  intellectual  property
rights  to its proprietary vitrification  and other waste treatment technologies
from the inventors of such technologies. Drs. Macedo and Litovitz, the inventors
of the  Company's  vitrification  and ion  exchange  technologies,  license  the
patents  and proprietary  rights to  such technologies  to the  Company under an
exclusive license agreement. Under this  agreement, which was renewed in  August
1992,  Drs. Macedo and  Litovitz collectively receive  annual royalties equal to
the greater of (i) $100,000 or (ii) 1%  to 3% of net revenues, depending on  the
level  of net revenues, which are generated  by the Company from the application
of the licensed  technology to encapsulate  liquids and solids  in porous  glass
matrices,  remove radioactive and hazardous materials from liquids and stabilize
low-level radioactive or mixed waste. During the three years ended December  31,
1995,  the Company  paid Drs.  Macedo and  Litovitz the  $100,000 minimum annual
royalty each year. The exclusive license agreement with Drs. Macedo and Litovitz
expires upon the expiration of the last patent covered by the license  agreement
which  is currently  in the  year 2012. Drs.  Macedo and  Litovitz also received
options to purchase 250,000 shares of the Common Stock at the time the exclusive
license  was  renewed.   The  exclusive  license   agreement,  which   currently
encompasses  22 patents  and one patent  application, also  includes any process
patents or technology rights related to the licensed field which is subsequently
developed by the VSL or Drs. Macedo and Litovitz.
 
                                       14
<PAGE>
    Drs. Macedo  and Litovitz  own all  of the  vitrification and  ion  exchange
patents  relating to the research and development  work conducted by them at the
VSL. The  Catholic  University  of  America has  agreed  that  all  patents  and
technologies  developed at the VSL belong to Drs. Macedo and Litovitz and not to
the University.  In  turn, Drs.  Macedo  and Litovitz  exclusively  license  the
vitrification technology rights and process patents developed by them at the VSL
to the Company.
 
    The  rights to the proprietary vitrification technology for the treatment of
non-radioactive hazardous  wastes  and the  treatment  of radioactive  waste  in
Germany  are held by  Vitritek and are  licensed to Vitritek  by Drs. Macedo and
Litovitz. Under the  terms of  this license agreement,  the Company's  allocable
share of revenues from the joint venture are included within the royalty payment
obligations under the Company's exclusive license agreement with Drs. Macedo and
Litovitz for the vitrification of radioactive and mixed wastes.
 
    The  Company also licenses  the rights to  the thermal desorption technology
used in the processing of petrochemical waste by DuraTherm from the inventor  of
such  technology. The Company  and DuraTherm are  co-licensees under the license
agreement and  are  collectively  obligated  to  pay  to  the  inventor  of  the
technology an annual royalty payment equal to the greater of (i) $50,000 or (ii)
1.0%  of the net revenues generated from the operation of the desorber equipment
(excluding net  revenues  generated from  equipment  acquired in  the  DuraTherm
acquisition)  incorporating the  technology and  5.0% of  the sales  of any such
equipment. Once certain aggregate royalty  obligations have been satisfied,  the
royalty  payment structure will be modified. The license agreement grants to the
Company  and  DuraTherm  the  exclusive  rights  to  such  technology  and   any
subsequently  developed related  technology and  provides that  any subsequently
developed unrelated  technology  which  results from  research  and  development
funded  or  sponsored by  the Company  or  DuraTherm shall  be assigned  to such
entities. The  license  agreement currently  covers  three patents  relating  to
thermal desorption, one pending patent and a European patent application.
 
    DuraTherm recently received an attorneys' letter on behalf of a company that
owns  certain thermal  desorption patent  rights. The  letter offers  to license
these  rights  to  DuraTherm.  These  attorneys  have  brought  several   patent
infringement  cases relating to these patents which are currently pending before
federal courts or have  been settled upon the  execution of license  agreements.
Although the letter does not assert patent infringement claims, no assurance can
be  given that such claims will not be asserted in the future. Management of the
Company and special patent counsel for the Company have reviewed the matter  and
have  determined that most  of the patents  cited in the  letter relate to waste
streams containing contaminants  that DuraTherm  does not process  or intend  to
process  and  that no  infringement of  these patent  claims exists.  Two patent
claims cited  in the  letter  are so  broad as  to  cover many  waste  treatment
processes.  With respect to these patent claims, GTS Duratek has been advised by
its special patent counsel that it is doubtful whether the scope of these patent
claims can be expanded to cover DuraTherm's process in view, among other things,
of a  significant body  of prior  art. Accordingly,  management of  the  Company
believes that the ultimate outcome of this matter is unlikely to have a material
adverse effect on DuraTherm or on the Company taken as a whole.
 
    The Company requires each of its employees to enter into standard agreements
pursuant  to  which the  employee agrees  to  keep confidential  all proprietary
information of  the Company  and to  assign to  the Company  all rights  in  any
proprietary  information or technology  developed by the  employee during his or
her employment or  made thereafter as  a result of  any inventions conceived  or
work  done during such employment. Despite these precautions, it may be possible
for a third party to copy or  otherwise obtain and use the Company's  technology
without  authorization  or  to  develop  similar  technology  independently.  In
addition, effective patent  and trade  secret protection may  be unavailable  or
limited in certain foreign countries.

EMPLOYEES
 
    As of December 31, 1995, the  Company employed 512 employees, including  403
field-assigned employees performing services for clients, 68 full-time technical
personnel  and 41 in finance and administration. The Company contracts with most
of the field-assigned personnel on an as-needed basis and such personnel are not
full-time employees of  the Company.  Due to  the seasonality  of the  technical
support services business of the Company, the number of field-assigned employees
generally  increases to approximately 500 during  the fall peak outage season at
the nation's nuclear power plants. To  date, the Company has been successful  in
attracting and retaining qualified technical personnel, although there can be no
assurance  that this success will continue.  None of the Company's employees are
subject to a collective bargaining agreement. The Company has never  experienced
a work stoppage and believes that its relations with its employees are good.
 
ITEM 2.  PROPERTIES
 
    The  Company  leases approximately  14,200 square  feet  of office  space in
Columbia, Maryland which  it uses  as its administration  and general  corporate
offices.  The initial lease term  expired in 1995 but  has been extended through
November 1996. The  Company also leases  2,400 square feet  of space in  Laurel,
Maryland, which the Company uses as a warehouse for
DURASIL-Registered  Trademark-  ion exchange  media  and related  equipment, and
4,800 square  feet  in  Pittsburgh,  Pennsylvania  which  houses  the  Company's
instrument repair and rental facility.
 
    The   Company's  80%-owned  subsidiary,  DuraTherm,  owns  a  RCRA-permitted
hazardous waste recycling center located in San Leon, Texas that was  previously
operated by BEGCI. The facility is located on 14.5 acres of land and consists of
a  recycling center on 8.5 acres and  4,500 square feet of office and laboratory
space. The facility and the land are owned by DuraTherm.
 
ITEM 3.  LEGAL PROCEEDINGS
 
    From time to  time the Company  is a party  to litigation or  administrative
proceedings  relating to claims arising from its operations in the normal course
of business. Management of the Company, on the advice of counsel, believes  that
the  ultimate resolution of litigation currently  pending against the Company is
unlikely, either individually or  in the aggregate, to  have a material  adverse
effect on the Company's results of operations or financial condition.

    As  of February  22, 1996, there  were 678  holders of record  of the Common
Stock and the Company estimates  that there were approximately 1,700  beneficial
holders.
 
    The  Company has never declared or paid  a cash dividend on its Common Stock
and is currently prohibited  from paying dividends under  its revolving line  of
credit  with its  principal lender.  The Company  will pay  dividends on  the 8%
Cumulative Convertible Redeemable  Preferred Stock  (the "Convertible  Preferred
Stock")  out of funds legally available therefor in accordance with the terms of
the Convertible Preferred Stock which require the payment of quarterly dividends
of $320,000 or $2.00 per share. The Company may not pay dividends on any of  the
Common Stock unless the Company has paid all accumulated dividends on all of the
outstanding shares of Convertible Preferred Stock. To date, the Company has paid
all  dividends on  all of  the outstanding  shares of  the Convertible Preferred
Stock. Except with respect to the dividends on the Convertible Preferred  Stock,
the  Company currently intends to retain  earnings primarily for working capital
and  development  of  waste  treatment  technologies  and  therefore  does   not
anticipate   paying  any   cash  dividends   in  the   foreseeable  future.  See

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
OVERVIEW
 
    GTS  Duratek has historically derived substantially all of its revenues from
technical  support  services   to  government   agencies,  electric   utilities,
industrial  facilities and commercial businesses. Technical support services are
generally provided pursuant to multi-year time-and-materials contracts. Revenues
are recognized  as costs  are  incurred according  to predetermined  rates.  The
contract  costs primarily include direct labor, materials and the indirect costs
related to contract performance.
 
    Historically, the  Company's waste  treatment revenues  have been  generated
from projects in which the Company acts as a subcontractor for the United States
Department  of Energy  ("DOE") pursuant  to fixed-price  and cost-plus-fixed-fee
contracts. The Company began to offer vitrification services for wastes from the
DOE's Fernald Environmental Management Project in 1991 and began to operate  its
first  field-based DuraMelter-TM- at  Fernald in 1993.  Substantially all of the
Company's waste treatment revenues  during 1993 and 1994  were derived from  the
Fernald  project  and during  1995 were  derived from  the DOE's  Savannah River
M-Area  project.   Revenues  from   these  projects   are  recognized   on   the
percentage-of-completion  method  as  costs  are  incurred  as  measured  by the
cost-to-cost method.
 
    The Company  to date  has generated  minimal revenues  from waste  treatment
projects  for commercial customers.  Revenues from the  operations of commercial
waste treatment  facilities  will  be  recognized as  waste  is  processed.  The
Company's  current commercial  waste treatment  projects are  the DuraChem joint
venture ("DuraChem") with Chem-Nuclear, Inc. and DuraTherm, Inc.  ("DuraTherm"),
which  owns the San Leon, Texas thermal desorption facility. Income or loss from
the Company's 45%  share in  DuraChem will  be recorded  by the  Company on  the
equity  method. DuraTherm is  expected to commence  commercial operations in the
second quarter  of  1996. The  Company  consolidates the  results  of  DuraTherm
adjusting for the 20% minority interest in consolidation.
 
    In  November 1995, the  Company formed a strategic  alliance with BNFL, Inc.
("BNFL") to jointly pursue up to  five major DOE waste treatment projects.  BNFL
is  the  U.S.  subsidiary of  British  Nuclear  Fuels plc,  one  of  the largest
processors of  radioactive waste  in the  world. Pursuant  to the  terms of  the
strategic  alliance, the  Company will receive  a $1.0 million  teaming fee each
time that  BNFL and  the  Company agree  to jointly  pursue  a major  DOE  waste
treatment  project.  The  Company reached  agreements  to pursue  the  first two
projects in November 1995 and February  1996 and recognized as revenue the  $1.0
million  fees  in the  fourth quarter  of 1995  and the  first quarter  of 1996,
respectively. The Company  is unable  to predict  the timing  of recognition  of
future  teaming fees, if  any. In addition,  BNFL will provide  the Company with
research and development funding of $500,000 annually for five years, which will
be used to offset certain of the Company's research and development expenses.
 
    The timing of new waste treatment projects, including those pursued  jointly
with  BNFL, the duration of these projects, and the form in which these projects
are owned and operated will affect period-to-period comparisons of the Company's
operating results.
 
RESULTS OF OPERATIONS
 
  YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
    Revenues increased by $4.4 million or  12.4%, from $36.0 million in 1994  to
$40.4  million in 1995. The increase was  primarily the result of an increase in
revenues from waste  treatment projects,  which were  $6.7 million  in 1994  and
$11.1  million in 1995. The most significant  of the waste treatment projects is
the Savannah  River M-Area  project with  Westinghouse Savannah  River  Company.
Under  this three-year,  $14.1 million contract,  the Company  has constructed a
vitrification facility at the Savannah River  site in South Carolina to  convert
approximately  90,000 cubic feet  of mixed waste to  stable glass. Revenues from
this contract  were $2.3  million in  1994 and  $6.1 million  in 1995.  Revenues
 
                                       20
<PAGE>
in  1995 also include a $1.0 million  teaming fee received from BNFL in exchange
for the  Company's  agreement to  exclusively  team with  BNFL  on a  DOE  waste
treatment  project  in  Hanford,  Washington.  Revenues  from  technical support
services were $29.3 million in 1994 and $29.3 million in 1995.
 
    Gross profit increased by $1.1 million  or 15.3%, from $7.1 million in  1994
to  $8.2 million  in 1995. The  teaming fee from  BNFL represented approximately
$1.0 million  of  the  increase.  As a  percentage  of  revenues,  gross  profit
increased  from  19.8%  in 1994  to  20.3%  in 1995.  Gross  profits  from waste
treatment projects  were lower  in 1995  as compared  to 1994  principally as  a
result  of project mix and modifications to  the estimated costs to complete the
Savannah River M-Area project. The estimated cost to complete the Savannah River
M-Area project was increased  due to the Company's  decision to make  additional
investments  in the  on-site facility to  better position the  Company to handle
additional waste  streams at  that site.  Gross profits  from technical  support
services were $4.0 million in 1994 and $4.1 million in 1995.
 
    Selling,  general and administrative  expenses declined by  $50,000 or 0.8%,
from  1994  to  1995.  As  a  percentage  of  revenues,  selling,  general   and
administrative  expenses  declined from  16.5%  in 1994  to  14.5% in  1995. The
decline was  principally  the result  of  higher utilization  of  the  Company's
engineering  staff on  waste treatment projects  and joint ventures,  as well as
increased revenues without a corresponding increase in administrative overhead.
 
    In 1994, the Company  had net interest expense  of $595,000 compared to  net
interest  income of $57,000 in  1995. In January 1995,  the Company issued $16.0
million of convertible preferred stock, the net proceeds of which were  utilized
to  repay outstanding short-term  borrowings with the  balance being invested in
short-term investment grade securities.
 
    Income tax  expense  was $12,000  in  1994  compared to  $101,000  in  1995.
Utilization  of net operating loss carryforwards in 1994 and 1995 resulted in no
federal income taxes other than alternative minimum tax. The 1994 and 1995 state
income tax  amounts  relate to  income  taxes payable  to  states which  do  not
recognize  net operating loss  carryforwards. At December  31, 1995, the Company
has a net  operating loss carryforward  of approximately $2.2  million of  which
approximately  $1.1  million  resulted from  the  exercise by  employees  of the
Company of non-qualified stock options in 1995. Accordingly, utilization of this
$1.1 million of the net operating loss  carryforward will result in a credit  to
capital in excess of par.
 
    The  Company's  proportionate  share in  the  loss  of its  50%  owned joint
venture, Vitritek Environmental, Inc.  ("Vitritek"), increased from $321,000  in
1994  to  $824,000 in  1995.  Vitritek's 1995  loss  was the  result  of limited
business activity, as well as a $1.2 million write-off of Vitritek's  intangible
assets  related to asbestos vitrification technology rights. In 1995, management
of Vitritek  concluded that  the  market for  asbestos vitrification  would  not
develop  quickly  enough to  generate the  cash flows  necessary to  recover the
intangible assets acquired by Vitritek in 1993.
 
    Net income increased by $1.2 million or approximately 465% from $257,000  in
1994  to $1.5 million in  1995. The increase resulted  from higher revenues from
waste treatment projects, the receipt of  the BNFL $1.0 million teaming fee  and
lower interest expense offset by the higher loss resulting from the write-off of
intangible assets realized from the Vitritek joint venture.
 
  YEAR ENDED DECEMBER 31, 1993 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
    Revenues  increased by $2.5 million  or 7.4%, from $33.5  million in 1993 to
$36.0 million  in  1994.  The  increase  was  primarily  a  result  of  revenues
recognized on the Company's waste treatment projects, which were $3.7 million in
1993  and $6.7 million  in 1994, particularly the  Savannah River M-Area project
which commenced in 1994. Revenues from technical support services declined  from
$29.8 million in 1993 to $29.3 million in 1994.
 
    Gross  profit increased by $2.2 million or  45.2%, from $4.9 million in 1993
to $7.1 million  in 1994. As  a percentage of  revenues, gross profit  increased
from 14.6% in 1993 to 19.8% in 1994. The increase
 
                                       21
<PAGE>
primarily resulted from gross profits achieved on waste treatment projects which
generally  have a  higher gross profit  margin than  technical support services.
Gross profits from technical support services were $3.7 million in 1993 and $4.0
million in 1994.
 
    Selling, general and administrative expenses increased by $188,000 or  3.3%,
from  $5.7 million in 1993 to $5.9 million in 1994. As a percentage of revenues,
selling, general  and administrative  expenses declined  from 17.1%  in 1993  to
16.5%  in 1994. This decline was principally the result of higher utilization of
the Company's engineering staff on waste treatment projects and joint ventures.
 
    Net interest expense increased  from $372,000 in 1993  to $595,000 in  1994.
The  $223,000 increase was primarily the  result of higher short-term borrowings
on the Company's line of credit and higher interest rates.
 
    Income tax expense was $73,000 in 1993 compared to $12,000 in 1994. The 1993
and 1994 income tax amounts relate to state income taxes payable.
 
    The Company's 50% owned joint  venture, Vitritek, began operations in  1994.
The  Company's  proportionate  share  in  the  loss  of  Vitritek  was $321,000.
Vitritek's 1994 loss was  the result of the  entity's startup costs and  limited
business activity.
 
    In  1993, the Company had a net loss  of $1.3 million compared to net income
of $257,000 in 1994. The improvement in earnings resulted primarily from  higher
revenues from waste treatment projects.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    During  1995, the  Company completed  two significant  capital transactions,
which provided net proceeds of approximately $24.5 million. In January 1995, the
Company issued  to  investment  partnerships sponsored  and  controlled  by  the
Carlyle  Group for  $16.0 million,  160,000 shares  of 8%  convertible preferred
stock and an option to purchase an additional 1,250,000 shares of the  Company's
common  stock,  at any  time  prior to  January 24,  1999  for $3.75  per share.
Proceeds to  the Company,  net  of offering  expenses,  were $14.7  million.  In
November 1995, the Company issued to BNFL a $10.0 million convertible debenture,
which accrues interest at the one-year London Interbank Offered Rate (LIBOR) for
a  period of five years, for $9.8 million,  net of debt issue cost. In addition,
the Company  generated $2.0  million  upon the  exercise  of stock  options  and
warrants  held by employees and others. The Company used certain of the proceeds
from these transactions to retire short-term borrowings of $7.6 million with the
balance being used for working capital needs and to further the Company's  waste
treatment  technologies  through  acquisitions,  joint  ventures  and  strategic
alliances.
 
    During 1995, the  Company invested approximately  $4.5 million in  property,
plant  and  equipment,  the  DuraChem  joint  venture  and  an  acquisition. The
investments in property, plant and equipment and DuraChem related principally to
the construction of  DuraMelters-TM- and related  components. In November  1995,
the Company acquired 80% of the outstanding capital stock of DuraTherm, formerly
Bird  Environmental  Gulf Coast,  Inc.,  a company  which  operates a  RCRA Part
B-permitted waste  facility using  thermal desorption  technology in  San  Leon,
Texas.  The  Company purchased  its  interest in  DuraTherm  for one  dollar and
incurred approximately $260,000  of transaction  costs. In  connection with  the
acquisition,  the Company agreed to  invest up to $5.1  million in DuraTherm (of
which up to $2.7 million is for  capital improvements and up to $2.4 million  is
for  working capital) in exchange for  preferred stock of DuraTherm. The Company
presently expects  to invest  in  the aggregate  approximately $6.4  million  in
property,  plant and equipment, DuraTherm and  the DuraChem joint venture during
1996.
 
    During  1995,  the  Company  used  $847,000  of  cash  flows  for  operating
activities.  Cash  flows from  operations were  primarily  impacted by  the $4.0
million increase  in accounts  receivable and  costs and  estimated earnings  in
excess  of billings on  uncompleted contracts. Of the  $17.0 million in accounts
 
                                       22
<PAGE>
receivable and costs and estimated earnings in excess of billings on uncompleted
contracts at December 31, 1995, $10.5 million relates to contracts with two  DOE
contractors  which  are expected  to be  collected  in 1996.  The Company  has a
backlog of orders of approximately $48.0 million at December 31, 1995, of  which
approximately $23.0 million is expected to be completed in 1996.
 
    The  Company has a revolving line of  credit agreement with a bank providing
for borrowings  up to  $7.0  million based  upon  eligible amounts  of  accounts
receivable,  as  defined  in  the agreement.  Borrowings  outstanding  under the
agreement are due on demand and bear interest at the bank's prime interest  rate
plus  1% (9.25% as of March 14, 1996).  At December 31, 1995, no borrowings were
outstanding and the Company had available borrowings of $5.9 million.
 
    The Company believes cash flows from operations, cash resources available at
December 31, 1995 and, if necessary, borrowings available under the bank line of
credit will be  sufficient to  fund currently planned  capital improvements  and
meet its operating needs, including the quarterly preferred dividend requirement
of $320,000, for at least the next twelve months.
 
SEASONALITY
 
    Seasonality   generally  does  not  affect  the  Company's  waste  treatment
technology operations;  however,  it  does  have  an  effect  on  the  Company's
technical  support services business.  A large component  of the Company's staff
augmentation business  is devoted  to nuclear  power plant  outage support.  The
seasonal  nature of this work  is caused by utilities'  desire to schedule their
nuclear unit refueling and maintenance outages during spring and fall when,  due
to  moderate  temperatures, electrical  load demand  is  lowest. In  addition, a
significant portion  of the  Company's  computer and  communications  consulting
services  client base  is in  the federal,  state and  local government sectors.
Funding appropriations for many of these clients' projects are coordinated  with
the  government's  fiscal  years  which  causes  some  seasonal  impact  on this
business. In contrast to  the outage support business,  demand for computer  and
communications consulting services typically peaks in winter and summer months.
 
ACCOUNTING MATTERS
 
    The  Company  will  adopt  the  provisions  of  the  Statement  of Financial
Accounting  Standards  (SFAS)  No.  121,  "Accounting  for  the  Impairment   of
Long-Lived  Assets and Long-Lived  Assets to be  Disposed Of" and  SFAS No. 123,
"Accounting for Stock-Based Compensation" in 1996.  Adoption of SFAS No. 121  is
not  expected to have a  material impact on the  Company's financial position or
results of  operations for  1996.  Beginning in  1996,  the Company  expects  to
present  information required by SFAS No. 123 with respect to stock compensation
on a pro forma basis and will continue to measure stock compensation based  upon
the guidance provided in Accounting Principles Board Opinion No. 25.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
GTS Duratek, Inc.:
 
    We have audited the accompanying consolidated balance sheets of GTS Duratek,
Inc.  and  subsidiaries  as of  December  31,  1994 and  1995,  and  the related
consolidated statements of operations, stockholders'  equity and cash flows  for
each  of  the years  in the  three-year  period ended  December 31,  1995. 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 have 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 GTS Duratek,
Inc.  and subsidiaries as of December 31, 1994 and 1995 and the results of their
operations and their cash flows for each  of the years in the three-year  period
ended  December  31,  1995,  in conformity  with  generally  accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1994 AND 1995
 
1.  DESCRIPTION OF BUSINESS
    GTS  Duratek, Inc.  (the "Company")  provides waste  treatment solutions for
radioactive, hazardous,  mixed and  other  wastes. The  Company's  vitrificaton,
thermal  desorption and ion exchange technologies  convert waste to stable forms
for storage  or  disposal  while  achieving  significant  volume  reduction.  To
implement its waste treatment technologies and provide related technical support
services,  the Company has a staff  of highly skilled personnel with significant
environmental services experience. The services provided by the Company  include
staff  augmentation  and outage  support,  principally to  assist  nuclear power
plants  during  regular  maintenance   shutdowns,  environmental  and   computer
consulting and environmental safety training.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES
 
  PRINCIPLES OF CONSOLIDATION
 
    The  consolidated financial statements  include the accounts  of the Company
and its subsidiaries, all of which  are wholly-owned except for DuraTherm,  Inc.
which  is 80% owned. All significant intercompany balances and transactions have
been eliminated in consolidation. Investments in subsidiaries and joint ventures
in which the Company does not  have control or majority ownership are  accounted
for under the equity method.
 
  CASH AND CASH EQUIVALENTS
 
    For  purposes  of  the consolidated  statement  of cash  flows,  the Company
considers all highly liquid investments with initial maturities, at the date  of
purchase,  of three months or  less to be cash  equivalents. Cash equivalents at
December 31, 1995 were $11,121,008.
 
  INVENTORIES
 
    Inventories are valued at the lower of cost or market, principally using the
first in, first out (FIFO) method of costing.
 
  PROPERTY, PLANT, AND EQUIPMENT
 
    Property, plant and equipment are carried at cost. Replacements, maintenance
and repairs  which  do not  extend  the lives  of  the assets  are  expensed  as
incurred.  The  Company  provides  for  depreciation  of  property,  plant,  and
equipment when  such assets  become operational,  primarily on  a  straight-line
basis  over  useful lives  of  three to  ten  years. Leasehold  improvements are
amortized over the shorter of the asset life or the term of the lease.
 
  INTANGIBLES
 
    Intangible assets  consist  principally  of amounts  assigned  to  covenants
not-to-compete  and costs incurred to obtain  and maintain patents. Covenant and
patent amounts are being amortized  over ten and seventeen years,  respectively,
on  a straight-line basis. The Company assesses the recoverability of intangible
assets by determining whether  the amortization over the  remaining life of  the
asset  can be  recovered through undiscounted  future cash flows.  The amount of
impairment, if any,  is measured  based on projected  discounted operating  cash
flows.
 
  DEFERRED CHARGES
 
    Deferred  charges consist principally of costs related to the maintenance of
the  Company's   temporary   personnel   work   force   data   base,   including
certifications,  security  clearances and  related  information. Such  costs are
amortized over the term of the expected benefit which is generally two years.
 
  REVENUE RECOGNITION
 
    The Company generates substantially all of its revenue under fixed-price and
time-and-materials contracts.  Revenue  from  contracts  is  recognized  on  the
percentage-of-completion method as costs are

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES (CONTINUED)
incurred  and includes estimated fees at  predetermined rates as measured by the
cost-to-cost method. Contract costs include all direct labor, material costs and
the indirect costs related to contract performance. Differences between recorded
costs, estimated earnings  and final billings  are recognized in  the period  in
which  they  become  determinable. Costs  and  estimated earnings  in  excess of
billings on uncompleted contracts are recorded as assets. Billings in excess  of
costs   and  estimated  earnings  on   uncompleted  contracts  are  recorded  as
liabilities. Retainages,  amounts  subject  to future  negotiation  and  amounts
related to claims are not material.
 
    In  addition,  the Company  generates revenue  from  product sales  which is
recognized upon product shipment.
 
  INCOME TAXES
 
    Deferred tax assets and liabilities are recognized for the estimated  future
tax  consequences of temporary  differences between the  financial reporting and
tax bases of assets and  liabilities based on enacted  tax rates in effect  when
such  amounts are  expected to be  realized based on  consideration of available
evidence, including tax planning  strategies and other  factors. The effects  of
changes  in  tax  laws or  rates  on  deferred tax  assets  and  liabilities are
recognized in the period that includes the enactment date.
 
  FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The estimated  fair  value  of  financial  instruments,  including  accounts
receivable, accounts payable and long-term debt, approximate carrying value.
 
  USE OF ESTIMATES
 
    Management  of the  Company has made  a number of  estimates and assumptions
relating to  the  reporting  of  assets and  liabilities  and  their  respective
disclosures  to prepare  these consolidated  financial statements  in conformity
with generally  accepted  accounting  principles. Actual  results  could  differ
significantly from those estimates.
 
  NET INCOME (LOSS) PER SHARE
 
    The  net income  (loss) per share  for 1993,  1994 and 1995  was computed by
dividing the  net  income  (loss) attributable  to  common  stockholders,  which
reflects the preferred stock dividend requirement and accretion, by the weighted
average   number  of  shares  of  common  stock  outstanding  and  common  stock
equivalents to the extent  they result in additional  dilution. The Company  has
issued options and warrants which exceed 20% of the common stock outstanding and
accordingly,  the Company  determines the dilutive  effect of  such common stock
equivalents using  the  modified treasury  stock  method. For  the  years  ended
December 31, 1993, 1994 and 1995, the common stock equivalents were deemed to be
anti-dilutive  and, accordingly, are not included in the weighted average number
of shares used in determining net income (loss) per share.
 
  RECLASSIFICATIONS
 
    Certain amounts for 1993 and 1994  have been reclassified to conform to  the
presentation for 1995.
 
3.  INVENTORIES
    Inventories at December 31 consist of the following:

5.  JOINT VENTURES AND OTHER AGREEMENTS
    In  order  to commercialize  its vitrification  technology more  rapidly and
cost-effectively, the  Company has  developed several  joint venture  and  other
arrangements. The following is a summary of those relationships:
 
  BNFL, INC.
 
    On  November  7, 1995,  the Company  and  BNFL, Inc.  (BNFL) entered  into a
strategic alliance agreement.  BNFL is  the U.S. subsidiary  of British  Nuclear
Fuels plc, a United Kingdom-based company experienced in processing and treating
high  level radioactive  waste. Under the  terms of the  strategic alliance, the
Company and BNFL have agreed  to jointly pursue up  to five major United  States
Department  of Energy (DOE) waste treatment projects. The terms of the strategic
alliance provide that BNFL pay the Company a teaming fee of $1 million each time
the two  companies  agree  to  exclusively pursue  together  a  waste  treatment
project.  Upon the  execution of the  strategic alliance  agreement, the Company
received and recognized as revenue a $1 million fee for its agreement to  pursue
a project exclusively with BNFL at the DOE's Hanford, Washington facility.
 
    As  part of the strategic alliance, BNFL invested $10 million in the Company
in the form of a convertible debenture  (see note 10) and agreed to provide  the
Company with research and development funding of at least $500,000 per year over
the next five years.
 
  VITRITEK ENVIRONMENTAL, INC.
 
    Through  a  joint venture  with Vitritek  Holdings Company  L.L.C. (Vitritek
Holdings), a privately-held entity, the  Company has extended its  vitrification
technology  to non-radioactive hazardous waste. The joint venture entity, called
Vitritek Environmental, Inc. ("Vitritek"), is 50%  owned by each of the  Company
and  Vitritek Holdings. The  joint venture, formed  in December 1993, represents
the  consolidation  of  co-licensing  rights  to  non-radioactive  vitrification
technologies previously acquired by the Company and Vitritek Holdings. Under the
terms of the joint venture arrangement, all funding requirements and all profits
are shared equally.
 
    The  Company's investment in, and advances to, Vitritek at December 31, 1994
and 1995 were $1,837,323 and $1,121,027, respectively. As of December 31,  1995,
Vitritek  had  assets of  $2,697,136  and liabilities  of  $3,500,000 (including
$1,750,000 due to the Company). For the years ended December 31, 1994 and  1995,
Vitritek had net sales of $105,173 and $678,989, respectively, and net losses of
$891,152 and $1,997,655, respectively. For the years ended December 31, 1994 and
1995, the Company recognized its proportionate share of loss in the consolidated
statement of operations after intercompany eliminations.
 
  DURACHEM, INC.
 
    In   September   1994,   the   Company   and   Chem-Nuclear   Systems,  Inc.
(Chem-Nuclear), a subsidiary of WMX  Technologies, Inc., formed a joint  venture
to design, build and operate vitrification facilities

5.  JOINT VENTURES AND OTHER AGREEMENTS (CONTINUED)
to  process  commercial  radioactive  waste  for  disposal,  including low-level
radioactive wastes from nuclear  power plants, hospitals, research  laboratories
and   industrial  facilities.  The  Company  will  contribute  45%  of  facility
construction costs and share proportionately in the venture's profits or losses.
The new  venture  is  operating,  as  a  limited  partnership,  under  the  name
"DuraChem."  The Company's investment in, and  advances to, DuraChem at December
31,  1994  and  1995  of  $580,448  and  $2,938,051,  respectively,  related  to
construction of a facility in Barnwell, South Carolina.
 
6.  ACQUISITION OF DURATHERM, INC.
    In  November 1995, the Company acquired 80% of the outstanding capital stock
of  Bird  Environmental   Gulf  Coast,   Inc.,  since   named  DuraTherm,   Inc.
("DuraTherm"),  from  Bird  Environmental  Technologies,  Inc.,  a  wholly-owned
subsidiary  of  Bird   Corporation  ("Bird")   for  one   dollar  and   incurred
approximately  $260,000  of transaction  costs.  DuraTherm owns  and  operates a
hazardous waste facility using thermal desorption technology in San Leon, Texas.
In connection with the acquisition, Bird contributed approximately $1.3  million
of  cash to DuraTherm  immediately prior to the  acquisition to fund DuraTherm's
working capital deficit.
 
    The remaining 20% of the outstanding capital stock of the Company is held by
certain individuals (the "Minority  Shareholders") who developed the  technology
and  have  operated and  will  continue to  operate  the facility.  The Minority
Shareholders have  entered into  employment agreements  providing for  incentive
compensation  tied directly  to the financial  performance of  the facility. The
Company has  entered into  a stockholders'  agreement pursuant  to which,  among
other  terms and conditions, the Company has agreed to invest up to $5.1 million
(of which up to $2.7 million is for capital improvements and up to $2.4  million
is  for  working  capital)  in  DuraTherm in  exchange  for  preferred  stock of
DuraTherm. The Company provided approximately $645,000 of the capital needed  by
DuraTherm  during the fourth quarter of 1995 and will make the balance available
during the first quarter of 1996. The Company expects the plant to reopen during
the second quarter of 1996. As part of the purchase transaction the Company also
acquired, through a licensing arrangement,  the exclusive rights to the  thermal
desorption technology used by the facility.
 
    The Minority Shareholders have the right to "put" their stock to the Company
at  fair market value beginning in December  1999 or earlier upon the occurrence
of certain events. The Company has the right to "call" the stock of the Minority
Shareholders at fair market value beginning in December 2001 or earlier upon the
occurrence of certain events.
 
    The acquisition of DuraTherm was accounted for using the purchase method  of
accounting.  The  estimated  fair  value of  the  net  tangible  assets acquired
exceeded the purchase price at November 29, 1995. Accordingly, the net  purchase
price in excess of the net carrying value of DuraTherm of approximately $238,000
was  allocated  to property,  plant and  equipment.  The Company  determined the
amount of the  minority interest of  the subsidiary  based upon 20%  of the  net
assets of DuraTherm at the date of acquisition.
 
    Pro  forma results of operations of the Company for the years ended December
31, 1994 and 1995, assuming the acquisition of DuraTherm had occurred on January
1, 1994, are as follows:

operation  of the  Company with  DuraTherm under  management and  control of the
Company's personnel.
 
7.  SHORT-TERM BORROWINGS
    The Company has a revolving line  of credit agreement with a bank  providing
for  borrowings  of up  to $7,000,000  based upon  eligible amounts  of accounts
receivable, as  defined  in  the agreement.  Borrowings  outstanding  under  the
agreement  are due on demand and bear interest at the bank's prime interest rate
plus 1% (9.5% at  December 31, 1995). Borrowings  outstanding under the line  of
credit are secured by the Company's accounts receivable, inventory and property,
plant  and equipment. The line of credit  agreement requires the Company to meet
certain financial  covenants  and restricts  the  payment of  dividends  on  the
Company's  common  stock.  At December  31,  1994, the  Company  had outstanding
borrowings of $7,630,512 under the agreement.  At December 31, 1995, no  amounts
were  outstanding and  approximately $5.9  million of  borrowings were available
under the line of credit agreement.

9.  LONG-TERM DEBT
    Long-term  debt  consists  of  notes payable  to  a  bank  requiring monthly
payments of principal plus interest at the bank's prime rate plus 1 1/4%  (9.75%
at  December 31, 1995). The notes payable  are secured by the Company's accounts
receivable, inventory and property, plant and equipment. The notes payable  have
aggregate annual maturities of $470,709 in 1996 and $36,000 in 1997.
 
10. CONVERTIBLE DEBENTURE
    In  November 1995, in connection with the formation of a strategic alliance,
the Company  received proceeds  of  $9,830,280, net  of  debt issue  costs  from
issuance  of a $10 million convertible  debenture to BNFL. The debenture accrues
interest during the first  five years at the  one-year London Interbank  Offered
Rate  (LIBOR).  The  debenture and  the  accrued interest  are  convertible into
1,381,575 shares of the  Company's common stock on  or before November 7,  2000.
The  debenture is to  be repaid in  annual installments over  a five-year period
commencing on  November 8,  2000.  The conversion  and  repayment dates  can  be
extended under certain circumstances. At December 31, 1995, the balance due BNFL
of $10,086,931 included accrued interest of $86,931.
 
    The  estimated fair value of the  convertible debenture at December 31, 1995
was approximately $14 million.
 
11. 8% CUMULATIVE CONVERTIBLE REDEEMABLE PREFERRED STOCK
    In January 1995, the  Company issued for $16  million, 160,000 shares of  8%
Cumulative Convertible Redeemable Preferred Stock, par value $.01 per share (the
"Convertible  Preferred Stock") and an option (the "Carlyle Option") to purchase
up   to    an    additional   1.25    million    shares   of    the    Company's

common  stock, at  any time  prior to January  24, 1999  for $3.75  per share to
investment  partnerships  sponsored   and  controlled  by   The  Carlyle   Group
("Carlyle").  The Convertible Preferred Stock  is initially convertible into the
Company's common  stock at  a  conversion price  of $3  per  share and,  if  not
previously  converted,  the  Company  is  required  to  redeem  the  outstanding
Convertible Preferred Stock on January 24, 2002 for $100 per share plus  accrued
and  unpaid dividends. The Company is required to pay quarterly dividends on the
Convertible Preferred Stock of $320,000.
 
    The proceeds, net of offering expenses  of $1,309,974, from the issuance  of
the  Convertible Preferred  Stock and Carlyle  Option were  $14,690,026 of which
$14,410,026 was allocated to  the Convertible Preferred  Stock and $280,000  was
allocated  to the fair value  of the Carlyle Option.  The difference between the
carrying value of the  Convertible Preferred Stock and  the redemption value  is
being accreted through charges to stockholders' equity over a six-year period to
January 24, 2002.
 
    The  estimated fair value of the Convertible Preferred Stock at December 31,
1995 was approximately $53 million.
 
12. STOCK OPTION PLANS AND WARRANTS
    The Company  has  a  non-qualified  Stock Option  Plan  (the  "Plan")  which
authorizes  a committee of the  Board of Directors to  grant options to purchase
shares of the Company's common stock to directors, officers and employees of the
Company. The exercise price of such options may not be less than 85% of the fair
market value of the common  stock on the date of  grant and the exercise  period
may  not be more than ten years after such date. Changes in options and warrants
outstanding, options and warrants exercisable  and shares reserved for  issuance
are as follows:

    In assessing the realizability of deferred tax assets, management considered
whether it was more likely than not that some portion or all of the deferred tax
assets  will be realized. The ultimate realization of the deferred tax assets is
dependent upon the generation of future  taxable income during periods in  which
temporary differences become deductible. Management considered income taxes paid
during  the previous three  years and projected future  taxable income in making
this  assessment.  Based  upon  the  level  of  historical  taxable  income  and
projections  for future taxable  income over the periods  in which the temporary
differences are deductible, management has established a valuation allowance  at
December 31, 1995 of $800,000.
 
    At  December 31, 1995,  the Company has net  operating loss carryforwards of
approximately $2.2 million which are available to offset future taxable earnings
of the Company through 2008. Approximately $1.1 million of the $2.2 million  net
operating  loss  carryfoward  is available  as  the  result of  the  exercise of
non-qualified stock options  by employees  of the Company.  Income tax  benefits
resulting from utilization of this portion of the net operating loss will result
in a credit to capital in excess of par.

13. INCOME TAXES (CONTINUED)
Utilization of approximately $1.6 million of the $2.2 million net operating loss
carryforward  is subject  to a  separate return  limitation, whereby  it is only
available to offset earnings from one of the Company's subsidiaries.
 
14. PROFIT SHARING PLAN
    The Company maintains a  Profit Investment Plan  (the "Plan") for  employees
who  have  completed one  year of  service  with the  Company. The  Plan permits
pre-tax contributions to the Plan by participants pursuant to Section 401(k)  of
the Internal Revenue Code of 1% to 14% of base compensation. The Company matches
25%  of the participants' eligible contributions based on a formula set forth in
the Plan and may make additional matching contributions. Employer  contributions
vest  at a rate of 20% per year of service. The Company's matching contributions
were $73,000, $74,000 and $162,000 for  the years ended December 31, 1993,  1994
and 1995, respectively.
 
15. BUSINESS AND CREDIT CONCENTRATIONS
    The  Company's  revenues are  derived primarily  from utilities  and through
subcontracts from  a  combination  of DOE  contractors  and  subcontractors.  At
December  31, 1995, approximately 87% of  the Company's accounts receivable were
due from these entities. Accounts receivable and costs and estimated earnings in
excess of  billings on  uncompleted contracts  relating to  DOE contractors  and
subcontractors  amounted to $2,226,023  and $2,857,336 at  December 31, 1994 and
$5,115,785 and  $7,591,628 at  December  31, 1995,  respectively. In  1993,  two
customers  comprised 20% and 15% of the  Company's annual revenues. In 1994, one
customer comprised  23%  of  the  Company's  annual  revenues.  In  1995,  three
customers  comprised  23%,  17%  and  16%  of  the  Company's  annual  revenues,
respectively. Revenues from DOE contracts and subcontracts were 13%, 23% and 35%
of annual  revenues  for the  years  ended December  31,  1993, 1994  and  1995,
respectively.
 
    The  Company  estimates  an allowance  for  doubtful accounts  based  on the
creditworthiness of  its  customers, as  well  as general  economic  conditions.
Consequently,  an adverse  change in  those factors  could affect  the Company's
estimate of its bad debts.
 
16. COMMITMENTS AND CONTINGENCIES
 
  ROYALTY AGREEMENTS
 
    The Company  has entered  into  an exclusive  licensing agreement  with  the
owners  of  the  vitrification technology,  pursuant  to which  the  owners have
granted to the  Company the exclusive  license and rights  to all  vitrification
technology  and  process patents  which  they developed.  The  exclusive license
agreement expires 17 years after the  last licensed patent is granted, which  at
this  time will  be in  2012. The  agreement provides  for a  guaranteed minimum
royalty of $100,000 per year throughout  the term of the agreement. Pursuant  to
the  agreement, royalty  expense was  limited to $100,000  in each  of the years
ended December  31, 1993,  1994 and  1995.  Beginning in  1996, the  Company  is
obligated to make payments of 1% to 3% of net sales values, as defined. Assuming
the  Company achieves a net sales value in  1996 equal to that achieved in 1995,
royalty expense will be approximately $260,000.
 
    The Company also licenses  the rights to  the thermal desorption  technology

  CLOSURE BOND
 
    Under  the State of Texas Civil Statue,  the Company is required to fund, in
the form of  a closure  bond, approximately  $1,936,000 over  a ten-year  period
which  will  be available  to cover  closure expenses  of the  DuraTherm thermal
desorption facility in  San Leon, Texas,  when and if  required. The funding  is
maintained in an interest bearing trust account and as of December 31, 1995, the
trust  balance  was approximately  $525,000. Such  amount  is included  as other
assets in the Company's consolidated balance sheet.
 
  LEGAL PROCEEDINGS
 
    The Company is involved in various  claims and legal actions arising in  the
ordinary  course  of  business.  In  the  opinion  of  management,  the ultimate
disposition of these  matters will  not have a  material adverse  effect on  the
Company's consolidated financial position or results of operations.
 
17. SUPPLEMENTAL CASH FLOW INFORMATION
    In  1993, the Company acquired certain rights to medical and hazardous waste
technologies from an unrelated third party  for a warrant valued at $500,000  to
purchase 500,000 shares of the Company's common stock through September 30, 1997
at $4.00 per share.

INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Vitritek Environmental, Inc.:
 
We have audited the accompanying balance sheets of Vitritek Environmental,  Inc.
as  of December  31, 1994  and 1995  and the  related statements  of operations,
stockholders' equity and cash  flows for the years  then ended. These  financial
statements   are   the   responsibility  of   the   Company's   management.  Our
responsibility is to express an opinion  on these financial statements based  on
our audits.
 
We   conducted  our  audits  in  accordance  with  generally  accepted  auditing
standards. Those standards require that we plan and perform the audit to  obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In  our opinion, the  financial statements referred to  above present fairly, in
all material respects, the financial position of Vitritek Environmental, Inc. as
of December 31, 1994 and 1995 and the results of their operations and their cash
flows for the years then ended in conformity with generally accepted  accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1994 AND 1995
 
(1) ORGANIZATION, DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
    Vitritek  Environmental, Inc. (the "Company") is  a corporate  joint venture
formed on December  28, 1993 to  market and commercialize  technologies for  the
vitrification of non-radioactive asbestos, medical and hazardous waste.
 
    The  Company is 50% owned by Vitritek Holdings Company, L.L.C. (VHC) and 50%
owned by GTS  Duratek, Inc. (GTS).  On the date  of formation, the  stockholders
contributed  in exchange for 500,000 shares  each of the Company's Common Stock,
medical and  hazardous waste  technology which  they had  jointly acquired  from
Environmental Corporation of America for $1 million in October 1993.
 
    In  addition, the parties jointly contributed  $2.5 million of equipment and
asbestos vitrification technology in exchange for notes payable of $1,750,000 to
VHC and $750,000 to GTS. The stockholders of VHC had developed the technology in
a predecessor  entity  which was  merged  into  the Company.  GTS  acquired  its
interest  in  the equipment  and  technology at  the  date of  formation through
issuing shares of its common stock valued at $750,000 to the stockholders of the
predecessor entity.
 
    In connection with the joint venture agreement, GTS agreed to fund the first
$1 million of operating costs  through issuance of notes  on the same terms  and
conditions  as the VHC note  payable. As of December 31,  1995 and 1994, GTS had
funded $1,000,000 and $887,432 of its obligation, respectively.
 
    During 1995, the  stockholders agreed to  contribute an additional  $150,000
each  to the Company. At December 31,  1995, $65,306 of the capital contribution
had been received. In the event  that the Company requires additional funds  the
stockholders have the ability and intent to support the Company through 1996.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  MACHINERY AND EQUIPMENT
 
    Machinery  and  equipment  are carried  at  cost. The  Company  provides for
depreciation when such assets become operational on a straight-line basis over a
ten-year estimated useful life. Replacements,  maintenance and repairs which  do
not extend the lives of the assets are expensed as incurred.
 
  INTANGIBLES
 
    Intangible  assets  consist  principally of  amounts  assigned  to asbestos,
medical and hazardous waste technology rights. These amounts are being amortized
over 20 years, on a straight-line basis. The Company assesses the recoverability
of intangible assets by determining whether the amortization over the  remaining
life  of the assets can be recovered through undiscounted future cash flows. The
amount of  impairment,  if  any,  is  measured  based  on  projected  discounted
operating cash flows.
 
  REVENUE RECOGNITION
 
    The  Company generates  substantially all  of its  revenue under fixed-price
contracts. Revenue from contracts is recognized on the  percentage-of-completion
method  as costs are incurred and includes estimated fees at predetermined rates
as measured by the cost-to-cost basis. Contract costs include all direct  labor,
material   costs  and  the  indirect  costs  related  to  contract  performance.
Differences between recorded  costs, estimated earnings  and final billings  are
recognized  in the period in which they become determinable. Costs and estimated
earnings in excess of billings on uncompleted contracts are recorded as  assets.
Billings  in excess of costs and estimated earnings on uncompleted contracts are
recorded as liabilities. Retainages, amounts  subject to future negotiation  and
amounts related to claims are not material.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
  INCOME TAXES
 
    Deferred  tax assets and liabilities are recognized for the estimated future
tax consequences of  temporary differences between  the financial reporting  and
tax  bases of assets and  liabilities based on enacted  tax rates in effect when
such amounts are expected to be realized or settled. Recognition of deferred tax
assets is limited to amounts expected  to be realized based on consideration  of
available  evidence, including  tax planning  strategies and  other factors. The
effects of changes in tax laws or  rates on deferred tax assets and  liabilities
are recognized in the period that includes the enactment date.
 
  FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The  estimated fair value  of financial instruments,  consisting of accounts
receivable and due to GTS Duratek, Inc. approximate carrying value.
 
  USE OF ESTIMATES
 
    Management of the  Company has made  a number of  estimates and  assumptions
relating  to  the  reporting  of assets  and  liabilities  and  their respective
disclosures to prepare these financial  statements in conformity with  generally
accepted  accounting principles. Actual results  could differ significantly from
those estimates.
 
(3) NOTES PAYABLE
    The Company has notes payable  of $1,750,000 due to each  of VHC and GTS  at
December  31, 1995.  The notes  bears interest  at prime  rate plus  1% (9.5% at
December 31,  1995)  and are  due  on December  22,  2003. Interest  is  payable
semi-annually on June 30 and December 31, of each year.
 
    Accrued  interest on notes payable to VHC  and GTS through December 31, 1994
and 1995  of  $248,037  and $350,000  was  forgiven  by the  parties  through  a
contribution to capital, respectively.
 
(4) WRITE-OFF OF INTANGIBLE ASSET
    During  1995,  management  of the  Company  determined that  the  market for
asbestos waste virtification  was not  developing as  expected, not  due to  the
viability  of the technology but  rather as a result  of the economic factors in
the marketplace.  Currently, traditional  asbestos  waste disposal  methods  are
significantly less expensive than vitrification. When the technology rights were
acquired  in 1993,  the Company had  several promising  opportunities which have
never came to fruition.
 
    While the  Company  will  continue to  monitor  the  asbestos  vitrification
market,  management  presently believes  it is  unlikely  that the  Company will
generate any cash flows from these activities in the near term and  accordingly,
has  written-off the carrying value of  the technology right related to asbestos
vitrification of $1,211,607 in  the statement of operations  for the year  ended
December 31, 1995.
 
(5) INCOME TAXES
    At  December 31, 1995, the Company has  a net operating loss carryforward of
approximately $650,000 which is available  to offset future taxable earnings  of
the  Company through 2009. Deferred tax assets at December 31, 1995 and 1994 are
offset by a valuation allowance.
 
(6) BUSINESS AND CREDIT CONCENTRATIONS
    The Company's revenues from  1995 are derived  primarily from two  customers
and at December 31, 1995, all of the Company's accounts receivable were due from
these entities.

(7) COMMITMENTS AND CONTINGENCIES
    The Company has licensed from two scientists, who are currently stockholders
of  VHC,  certain  proprietary  technology  relating  to  asbestos,  medical and
hazardous waste  vitrification.  The agreement,  as  amended October  15,  1993,
expires  17  years  after  the  effective date  of  the  agreement  or  upon the
expiration of  the  last  expiring  patent, whichever  shall  occur  later.  The
agreement  stipulates  the Company  make  royalty payments  attributable  to the
licensed technology. The  Company made  three quarterly payments  of $50,000  in
1994 and four quarterly payments of $20,000 in 1995.
