                                    ABOUT US

      We are a world  leader  in  primary  and  refuelable  Zinc-Air  fuel  cell
technology, engaging directly and through our subsidiaries in the use of battery
technology for defense and security products and other military applications and
for electric vehicles, in car armoring,  and in interactive multimedia training.
Until September 17, 2003, we were known as Electric Fuel Corporation. We operate
in three business units:

      >     we develop,  manufacture and market advanced hi-tech  multimedia and
            interactive  digital solutions for use-of-force and driving training
            of military,  law  enforcement  and security  personnel,  as well as
            offering homeland security consulting and other services;

      >     we pioneer  advancements in Zinc-Air and lithium battery  technology
            for defense and security  products and other  military  applications
            and for electric vehicles; and

      >     we  utilize   sophisticated   lightweight   materials  and  advanced
            engineering processes to armor vehicles.

SIMULATION, TRAINING AND CONSULTING

      USE-OF-FORCE TRAINING

            Through our wholly-owned  IES Interactive  Training  subsidiary,  we
provide  specialized  "use of force"  training  for  police,  homeland  security
personnel  and  the  military.   We  offer  products  and  services  that  allow
organizations  to train  their  personnel  in safe,  productive,  and  realistic
environments.  We believe that our training  systems  offer more  functionality,
greater flexibility, unprecedented realism and a wider variety of user interface
options  than  competing  products.   Our  systems  are  sold  to  corporations,
government  agencies,  military  and law  enforcement  professionals  around the
world.  The simulators are currently used by some of the worlds leading training
academies,  including (in the United States) the Secret  Service,  the Bureau of
Alcohol,  Tobacco and  Firearms,  the  Houston  Police  Department,  the Customs
Service,  the Border  Patrol,  the Bureau of Engraving and  Printing,  the Coast
Guard, the Federal Law Enforcement Training Centers,  the California  Department
of Corrections,  the Detroit Police  Department,  the Washington DC Metro Police
and international  users such as the Israeli Defense Forces, the German National
Police,  the Royal  Thailand Army,  the Hong Kong Police,  the Russian  Security
Police, and over 400 other training departments worldwide.

            Our interactive  training systems range from the powerful Range 3000
use-of-force  simulator  system  to the  multi-faceted  A2Z  Classroom  Training
system.  The Range  3000 line of  simulators  addresses  the entire use of force
training  continuum  in law  enforcement,  allowing  the trainee to use posture,
verbalization,  soft hand skills,  impact  weapons,  chemical  spray,  low-light
electronic  weapons and lethal force in a scenario based classroom  environment.
The A2Z  Classroom  Trainer  provides  the  trainer  with real  time  electronic
feedback from every student through wireless handheld  keypads.  The combination
of interactivity  and instant response assures that learning takes place in less
time with higher retention.

      VEHICLE SIMULATORS

            Through our wholly-owned  subsidiary,  FAAC Corporation,  we provide
simulators,  systems  engineering  and  software  products to the United  States
military,   government   and  private   industry.   FAAC's   fully   interactive
driver-training  systems feature  state-of-the-art  vehicle simulator technology
enabling  training in situation  awareness,  risk analysis and decision  making,
emergency  reaction  and  avoidance  procedures,   and  conscientious  equipment
operation.  FAAC has an installed base of 169 simulators that have  successfully
trained over 78,000  drivers.  FAAC's customer base includes all branches of the
Department of Defense, state and local governments, and commercial entities.

            FAAC is the premier developer of validated, high fidelity analytical
models and  simulations of tactical air and land warfare for all branches of the
Department  of  Defense  and its  related  industrial  contractors.  Simulations
developed by FAAC are found in systems ranging from  instrumented air combat and
maneuver ranges (such as Top Gun) to full task training devices such as the F-18
Weapon Tactics Trainer.

            FAAC supplies  on-board  software to support weapon launch decisions
for the F-15,  F-18,  and Joint Strike  Fighter (JSF) fighter  aircraft.  Pilots
benefit by having highly accurate  presentations of their weapon's capabilities,
including  susceptibility  to target  defensive  reactions.  FAAC  designed  and
developed an Instructor  Operator Station (IOS),  Mission Operator Station (MOS)
and real-time,  database  driven  Electronic  Combat  Environment  (ECE) for the
Special  Operational  Forces  Aircrew  Training  System  (SOF ATS).  The SOF ATS
provides a full  range of aircrew  training,  including  initial  qualification,
mission  qualification,  continuation,  and upgrade training,  as well as combat
mission rehearsal.

      SECURITY CONSULTING

            Through our wholly-owned Arcon Security Corporation  subsidiary,  we
focus on  protecting  life,  assets and  operations  with  minimum  hindrance to

security  consulting  and other  services,  has signed an agreement  with Rafael
Armament  Development  Authority Ltd.,  Israel's  leading  defense  research and
Development  Company,  to market  and  implement  certain of  Rafael's  Homeland

BATTERIES, CHARGERS AND POWER SYSTEMS

      ZINC-AIR FUEL CELLS, BATTERIES AND CHARGERS FOR THE MILITARY

            We conduct our Zinc-Air  battery  business  through our wholly-owned
subsidiary  Electric  Fuel  Battery  Corporation.  We believe  that our Zinc-Air
batteries  provides the highest energy and power density  combination  available
today in the defense market,  making them  particularly  appropriate  where long
missions are required and low weight is important.

            Our line of existing  battery  products for the military and defense
sectors  includes  Advanced  Zinc-Air  Power Packs  (AZAPPs)  utilizing our most
advanced cells (which have specific  energy of 400  watt-hours per kilogram),  a
line of super-lightweight AZAPPs that feature the same 400 Wh/kg cell technology
in smaller cells, and our new,  high-power  Zinc-Air Power Packs (ZAPPs),  which
offer extended-use portable power using our commercial Zinc-Air cell technology.
Our AZAPPs  have  received  a National  Stock  Number (a  Department  of Defense
catalog number  assigned to products  authorized for use by the U.S.  military),
making our AZAPPs available for purchase by all units of the U.S. Armed Forces.

            We are  continuing to expand the  development of other advanced uses
of our battery  technology  for  applications  that demand high energy and light
weight.  We  also  produce  water-activated  lifejacket  lights  for  commercial
aviation and marine  applications,  and will pursue  further  development of the
safety products business.

      LITHIUM BATTERIES AND CHARGING SYSTEMS FOR THE MILITARY

            Recent   developments  and  improvements  in  lithium   rechargeable
batteries  have caused the US military,  as well as armies  worldwide,  to shift
many  battery-operated   devices  to  cost-effective   rechargeable   batteries.
Non-rechargeable  batteries  continue to be the leading  source of energy in war
and  during  limited  conflicts.  For more  than  ten  years,  our  wholly-owned
subsidiary   Epsilor  Electronic   Industries,   Ltd.  has  developed  and  sold
rechargeable  and primary lithium  batteries and smart chargers to the military,
and to private industry in the Middle East, Europe and Asia.

      ELECTRIC VEHICLE

            Our  Electric  Vehicle  effort,  conducted  through  our  subsidiary
Electric  Fuel  Battery  Corporation,   continues  to  focus  on  obtaining  and
implementing  demonstration  projects in the U.S.  and  Europe,  and on building
broad industry  partnerships that can lead to eventual  commercialization of the
Zinc-Air energy system.  Our all-electric bus, powered by our Zinc-Air fuel cell
technology,  has demonstrated a world-record 127-mile range under rigorous urban
conditions,  and we have successfully  demonstrated our vehicle in "on-the-road"
programs,  most recently in public tests in Las Vegas, Nevada and in Washington,
D.C., on Capitol Hill.

                                  RISK FACTORS

  AN INVESTMENT IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD
  CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS AND OTHER INFORMATION IN THIS
   PROSPECTUS IN ADDITION TO OUR FINANCIAL STATEMENTS BEFORE INVESTING IN OUR
    COMMON STOCK. IN ADDITION TO THE FOLLOWING RISKS, THERE MAY ALSO BE RISKS
     THAT WE DO NOT YET  KNOW OF OR THAT  WE CURRENTLY  THINK ARE IMMATERIAL
      THAT MAY ALSO  IMPAIR OUR  BUSINESS OPERATIONS. THE  TRADING PRICE OF
       OUR COMMON STOCK COULD DECLINE DUE TO ANY OF THESE RISKS, AND YOU
                     MAY LOSE ALL OR PART OF YOUR INVESTMENT.

BUSINESS-RELATED RISKS

      WE HAVE HAD A HISTORY OF LOSSES AND MAY INCUR FUTURE LOSSES.

            We were  incorporated  in 1990 and began our  operations in 1991. We
have funded our operations  principally from funds raised in each of the initial
public offering of our common stock in February 1994;  through subsequent public
and  private  offerings  of our  common  stock and  equity  and debt  securities
convertible  into  shares of our common  stock;  research  contracts  and supply
contracts;  funds  received  under  research  and  development  grants  from the
Government  of  Israel;  and  sales  of  products  that we and our  subsidiaries
manufacture.  We have periodically  incurred significant  operating losses since
our  inception.  Additionally,  as of September 30, 2003, we had an  accumulated
deficit of approximately $104.4 million.  There can be no assurance that we will
ever be able to maintain  profitability  consistently  or that our business will
continue to exist.

      OUR  EXISTING  INDEBTEDNESS  MAY  ADVERSELY  AFFECT OUR  ABILITY TO OBTAIN
ADDITIONAL  FUNDS AND MAY  INCREASE  OUR  VULNERABILITY  TO ECONOMIC OR BUSINESS
DOWNTURNS.

            Our  indebtedness  aggregated   approximately  $6.9  million  as  of
September 30, 2003.  Accordingly,  we are subject to the risks  associated  with
indebtedness, including:

            o     we must  dedicate a portion of our cash flows from  operations
                  to pay debt service costs and, as a result, we have less funds
                  available  for  operations,  future  acquisitions  of consumer
                  receivable portfolios, and other purposes;

            o     it may be more  difficult and  expensive to obtain  additional
                  funds through financings, if available at all;

            o     we are more vulnerable to economic  downturns and fluctuations
                  in  interest  rates,   less  able  to  withstand   competitive
                  pressures  and less  flexible  in  reacting  to changes in our
                  industry and general economic conditions; and

            o     if we default under any of our existing debt instruments or if
                  our  creditors  demand  payment  of a  portion  or  all of our
                  indebtedness,  we may not have  sufficient  funds to make such
                  payments.

The  occurrence  of any of these events could  materially  adversely  affect our
results of  operations  and financial  condition and adversely  affect our stock
price.

            The  agreements  governing  the  terms  of  our  debentures  contain
numerous  affirmative  and negative  covenants  that limit the discretion of our
management with respect to certain  business  matters and place  restrictions on
us,  including  obligations  on our part to preserve and maintain our assets and
restrictions  on our ability to incur or guarantee  debt,  to merge with or sell
our assets to another  company,  and to make  significant  capital  expenditures
without the consent of the debenture  holders.  Our ability to comply with these
and other  provisions of such  agreements may be affected by changes in economic
or business conditions or other events beyond our control.


                                       6


      FAILURE  TO COMPLY  WITH THE  TERMS OF OUR  DEBENTURES  COULD  RESULT IN A
DEFAULT THAT COULD HAVE MATERIAL ADVERSE CONSEQUENCES FOR US.

            A failure to comply with the obligations  contained in our debenture
agreements could result in an event of default under such agreements which could
result in an acceleration  of the debentures and the  acceleration of debt under
other instruments evidencing indebtedness that may contain cross-acceleration or
cross-default  provisions.  If the  indebtedness  under the  debentures or other
indebtedness  were to be accelerated,  there can be no assurance that our assets
would be sufficient to repay in full such indebtedness.

      WE HAVE  PLEDGED  A  SUBSTANTIAL  PORTION  OF OUR  ASSETS  TO  SECURE  OUR
BORROWINGS.

            Our debentures  are secured by a substantial  portion of our assets.
If we default under the indebtedness  secured by our assets,  those assets would
be available to the secured  creditors to satisfy our obligations to the secured
creditors, which could materially adversely affect our results of operations and
financial condition and adversely affect our stock price.

      WE NEED SIGNIFICANT AMOUNTS OF CAPITAL TO OPERATE AND GROW OUR BUSINESS.

            We require  substantial  funds to conduct  the  necessary  research,
development  and  testing  of  our  products;   to  establish  commercial  scale
manufacturing  facilities;  and to market  our  products.  We  continue  to seek
additional funding, including through the issuance of equity or debt securities.
However,  there can be no  assurance  that we will  obtain  any such  additional
financing in a timely manner or on  acceptable  terms.  If additional  funds are
raised by issuing equity securities, stockholders may incur further dilution. If
additional  funding is not  secured,  we will have to modify,  reduce,  defer or
eliminate parts of our anticipated future commitments and/or programs.

      WE MAY NOT BE SUCCESSFUL IN OPERATING A NEW BUSINESS.

            Prior to the IES and MDT acquisitions,  our primary business was the
marketing  and sale of products  based on primary and  refuelable  Zinc-Air fuel
cell technology and advancements in battery  technology for defense and security
products  and  other  military  applications,  electric  vehicles  and  consumer
electronics.  As a  result  of the  IES  and  MDT  acquisitions,  a  substantial
component of our business is the  marketing and sale of hi-tech  multimedia  and
interactive  digital  solutions  for  training  military,  law  enforcement  and
security  personnel  and  sophisticated   lightweight   materials  and  advanced
engineering  processes used to armor  vehicles.  These are new businesses for us
and our  management  group  has  limited  experience  operating  these  types of
businesses.  Although we have retained the management  personnel at IES and MDT,
we cannot  assure that such  personnel  will  continue to work for us or that we
will  be  successful  in  managing  this  new  business.  If we  are  unable  to
successfully  operate these new businesses,  especially the business of IES, our
business,  financial  condition  and results of  operations  could be materially
impaired.

      WE CANNOT ASSURE YOU OF MARKET ACCEPTANCE OF OUR MILITARY ZINC-AIR BATTERY
PRODUCTS AND ELECTRIC VEHICLE TECHNOLOGY.

            Our batteries for the defense industry and a signal light powered by
water-activated batteries for use in life jackets and other rescue apparatus are
the only commercial  Zinc-Air  battery  products we currently have available for
sale.  Significant  resources will be required to develop and produce additional
consumer products  utilizing this technology on a commercial  scale.  Additional
development will be necessary in order to commercialize  our technology and each
of the components of the Electric Fuel System for electric  vehicles and defense
products.  We cannot  assure you that we will be able to  successfully  develop,
engineer or commercialize our Zinc-Air energy system, or that we will be able to
develop products for commercial sale or that, if developed, they can be produced
in commercial quantities or at acceptable costs or be successfully marketed. The
likelihood  of our  future  success  must be  considered  in light of the risks,
expenses,  difficulties and delays frequently encountered in connection with the
operation  and  development  of a  relatively  early  stage  business  and  with
development activities generally.

            We believe  that public  pressure  and  government  initiatives  are
important factors in creating an electric vehicle market.  However, there can be
no  assurance  that there will be  sufficient  public  pressure or that  further
legislation or other governmental  initiatives will be enacted,  or that current
legislation will not be repealed,  amended, or have its implementation  delayed.
In  addition,  we are subject to the risk that even if an electric  fuel vehicle
market develops,  a different form of zero emission or low emission vehicle will
dominate the market.  In addition,  we cannot assure you that other solutions to
the problem of containing  emissions created by internal combustion engines will
not be invented,  developed  and  produced.  Any other  solution  could  achieve
greater market acceptance than electric  vehicles.  The failure of a significant
market for electric  vehicles to develop would have a material adverse effect on
our  ability  to  commercialize  this  aspect  of  our  technology.  Even  if  a
significant  market for electric  vehicles  develops,  there can be no assurance
that our technology will be commercially competitive within that market.


                                       7


      OUR ACQUISITION STRATEGY INVOLVES VARIOUS RISKS.

            Part of our strategy is to grow through the acquisition of companies
that will  complement  our existing  operations or provide us with an entry into
markets  we  do  not  currently  serve.  Growth  through  acquisitions  involves
substantial  risks,  including  the risk of improper  valuation  of the acquired
business and the risk of inadequate integration.  There can be no assurance that
suitable  acquisition  candidates  will  be  available,  that we will be able to
acquire  or  manage   profitably  such  additional   companies  or  that  future
acquisitions  will  produce  returns that justify our  investments  therein.  In
addition,  we may compete  for  acquisition  and  expansion  opportunities  with
companies that have  significantly  greater  resources than we do.  Furthermore,
acquisitions  could disrupt our ongoing business,  distract the attention of our
senior  managers,  make it  difficult  to maintain  our  operational  standards,
controls and  procedures  and subject us to contingent and latent risks that are
different, in nature and magnitude, than the risks we currently face.

            We may finance  future  acquisitions  with cash from  operations  or
additional debt or equity financings.  There can be no assurance that we will be
able to generate  internal cash or obtain  financing  from  external  sources or
that,  if  available,  such  financing  will be on terms  acceptable  to us. The
issuance  of  additional  common  stock to  finance  acquisitions  may result in
substantial  dilution to our stockholders.  Any debt financing may significantly
increase  our  leverage and may involve  restrictive  covenants  which limit our
operations.

      WE MAY NOT SUCCESSFULLY INTEGRATE OUR NEW ACQUISITIONS.

            In light of our recent acquisitions of IES and MDT, our success will
depend  in part on our  ability  to  manage  the  combined  operations  of these
companies and to integrate the operations and personnel of these companies along
with  our  other  subsidiaries  and  divisions  into  a  single   organizational
structure.  There  can be no  assurance  that we  will  be  able to  effectively
integrate   the   operations   of  our   subsidiaries   and  divisions  and  our
newly-acquired businesses into a single organizational structure. Integration of
these operations could also place additional pressures on our management as well
as on our key  technical  resources.  The  failure to  successfully  manage this
integration could have an adverse material effect on us.

            If we are  successful  in acquiring  additional  businesses,  we may
experience  a period of rapid  growth  that could place  significant  additional
demands on, and require us to expand,  our management,  resources and management
information  systems.  Our failure to manage any such rapid  growth  effectively
could have a material  adverse  effect on our  financial  condition,  results of
operations and cash flows.

      IF WE ARE UNABLE TO MANAGE  OUR  GROWTH,  OUR  OPERATING  RESULTS  WILL BE
IMPAIRED.

            We are  currently  experiencing  a period of growth and  development
activity which could place a significant  strain on our personnel and resources.
Our  activity  has  resulted  in  increased  levels of  responsibility  for both
existing and new management personnel. Many of our management personnel have had
limited or no experience in managing growing companies. We have sought to manage
our  current  and  anticipated  growth  through the  recruitment  of  additional
management and technical  personnel and the  implementation  of internal systems
and controls.  However, our failure to manage growth effectively could adversely
affect our results of operations.


                                       8


      WE WILL NEED TO  DEVELOP  THE  EXPERIENCE  TO  MANUFACTURE  CERTAIN OF OUR
PRODUCTS IN COMMERCIAL QUANTITIES AND AT COMPETITIVE PRICES.

            We currently have limited  experience in manufacturing in commercial
quantities  and have,  to date,  produced  only limited  quantities  of military
batteries and components of the batteries for electric vehicles. In order for us
to be successful in the commercial  market,  these products must be manufactured
to meet high quality standards in commercial  quantities at competitive  prices.
The  development  of the necessary  manufacturing  technology and processes will
require  extensive  lead  times and the  commitment  of  significant  amounts of
financial and engineering resources, which may not be available to us. We cannot
assure you that we will successfully develop this technology or these processes.
Moreover,  we cannot assure you that we will be able to  successfully  implement
the quality control measures necessary for commercial manufacturing.

      SOME OF THE  COMPONENTS OF OUR  TECHNOLOGY AND OUR PRODUCTS POSE POTENTIAL
SAFETY RISKS WHICH COULD CREATE POTENTIAL LIABILITY EXPOSURE FOR US.

            Some of the components of our  technology  and our products  contain
elements that are known to pose potential safety risks.  Also,  because electric
vehicle  batteries  contain large amounts of electrical  energy,  they may cause
injuries if not handled  properly.  In addition to these risks,  and although we
incorporate  safety  procedures in our research,  development and  manufacturing
processes,  there can be no assurance that accidents in our facilities  will not
occur.  Any  accident,  whether  occasioned by the use of all or any part of our
products or  technology  or by our  manufacturing  operations,  could  adversely
affect  commercial  acceptance  of our products and could result in  significant
production  delays or claims for damages  resulting from injuries.  Any of these
occurrences  would  materially  adversely  affect our  operations  and financial
condition.

      WE MAY FACE PRODUCT LIABILITY CLAIMS.

            To date,  there have been no material  claims or  threatened  claims
against us by users of our products, including the products manufactured by MDT,
based on a failure of our  products to perform as  specified.  In the event that
any claims for  substantial  amounts were to be asserted  against us, they could
have a  materially  adverse  effect on our  financial  condition  and results of
operations.  We maintain general product liability insurance.  However, there is
no  assurance  that the  amount of our  insurance  will be  sufficient  to cover
potential  claims or that the present  amount of insurance  can be maintained at
the present level of cost, or at all.

      SOME OF OUR BUSINESS IS DEPENDENT ON GOVERNMENT CONTRACTS.

            Most of IES's  customers  to date have been in the public  sector of
the U.S., including the federal, state and local governments,  and in the public
sectors of a number of other countries, and most of MDT's customers have been in
the  public  sector  in  Israel,   in   particular   the  Ministry  of  Defense.
Additionally,  all of our sales to date of our battery products for the military
and  defense  sectors  have been in the public  sector in the United  States.  A
significant  decrease in the overall level or allocation of defense  spending or
law  enforcement in the U.S. or other  countries  could have a material  adverse
effect on our future  results of  operations  and financial  condition.  MDT has
already  experienced  a slowdown in orders  from the  Ministry of Defense due to
budget  constraints  and a requirement  of U.S. aid to Israel that a substantial
proportion  of such  aid be  spent in the  U.S.,  where  MDT does not yet have a
factory in operation.

         Sales to public  sector  customers  are  subject to a  multiplicity  of
detailed  regulatory  requirements  and public policies as well as to changes in
training and purchasing  priorities.  Contracts with public sector customers may
be conditioned upon the continuing  availability of public funds,  which in turn
depends upon  lengthy and complex  budgetary  procedures,  and may be subject to
certain pricing  constraints.  Moreover,  U.S. government contracts and those of
many  international  government  customers  may  generally be  terminated  for a
variety  of  factors  when it is in the best  interests  of the  government  and
contractors may be suspended or debarred for misconduct at the discretion of the
government.  There can be no assurance  that these  factors or others  unique to
government  contracts or the loss or suspension of necessary regulatory licenses
will not have a material  adverse effect on our future results of operations and
financial condition.


                                       9


      OUR FIELDS OF BUSINESS ARE HIGHLY COMPETITIVE.

            The  competition  to  develop  defense  and  security  products  and
electric vehicle battery  systems,  and to obtain funding for the development of
these products, is, and is expected to remain, intense.

            Our defense and security  products compete with other  manufacturers
of specialized  training systems,  including Firearms Training Systems,  Inc., a
producer of interactive  simulation  systems designed to provide training in the
handling and use of small and  supporting  arms.  In  addition,  we compete with
manufacturers and developers of armor for cars and vans, including O'Gara-Hess &
Eisenhardt, a division of Armor Holdings, Inc.

            Our battery technology competes with other battery technologies,  as
well as  other  Zinc-Air  technologies.  The  competition  in  this  area of our
business consists of development stage companies,  major international companies
and consortia of such companies,  including  battery  manufacturers,  automobile
manufacturers,  energy production and transportation  companies,  consumer goods
companies  and defense  contractors.  Many of our  competitors  have  financial,
technical,  marketing,  sales,  manufacturing,  distribution and other resources
significantly greater than ours.

            Various  battery  technologies  are  being  considered  for  use  in
electric  vehicles and defense and safety  products by other  manufacturers  and
developers,  including the following:  lead-acid,  nickel-cadmium,  nickel-iron,
nickel-zinc,   nickel-metal  hydride,  sodium-sulfur,   sodium-nickel  chloride,
zinc-bromine,  lithium-ion,   lithium-polymer,   lithium-iron  sulfide,  primary
lithium, rechargeable alkaline and Zinc-Air.

            If we are unable to compete  successfully  in each of our  operating
areas, especially in the defense and security products area of our business, our
business and results of operations could be materially adversely affected.

      FAILURE TO RECEIVE REQUIRED  REGULATORY  PERMITS OR TO COMPLY WITH VARIOUS
REGULATIONS TO WHICH WE ARE SUBJECT COULD ADVERSELY AFFECT OUR BUSINESS.

            Regulations in Europe, Israel, the United States and other countries
impose various controls and requirements  relating to various  components of our
business.  While we believe that our current and contemplated operations conform
to those  regulations,  we cannot  assure you that we will not be found to be in
non-compliance.  We have applied for, and received,  the necessary permits under
the  Israel  Dangerous  Substances  Law,  5753-1993,  required  for  the  use of
potassium  hydroxide  and zinc metal.  However,  there can be no assurance  that
changes in these  regulations or the adoption of new regulations will not impose
costly  compliance  requirements  on us,  subject us to future  liabilities,  or
restrict our ability to operate our business.

      OUR BUSINESS IS DEPENDENT ON PATENTS AND OTHER PROPRIETARY RIGHTS THAT MAY
BE DIFFICULT TO PROTECT AND COULD AFFECT OUR ABILITY TO COMPETE EFFECTIVELY.

            Our  ability to compete  effectively  will  depend on our ability to
maintain the proprietary  nature of our technology and  manufacturing  processes
through a  combination  of patent and trade  secret  protection,  non-disclosure
agreements and licensing arrangements.  We hold patents, provisional patents, or
patent  applications,  covering  elements of our technology in the United States
and in Europe. In addition,  we have patent  applications  pending in the United
States and in foreign countries,  including the European  Community,  Israel and
Japan.  We intend to  continue to file patent  applications  covering  important
features of our  technology.  We cannot assure you,  however,  that patents will
issue from any of these  pending  applications  or, if patents  issue,  that the
claims  allowed  will be  sufficiently  broad  to  protect  our  technology.  In
addition, we cannot assure you that any of our patents will not be challenged or
invalidated,  that any of our issued  patents will afford  protection  against a
competitor or that third parties will not make infringement claims against us.

            Litigation, or participation in administrative  proceedings,  may be
necessary to protect our  proprietary  rights.  This type of  litigation  can be
costly and time  consuming and could divert  company  resources  and  management
attention  to defend  our  rights,  and this could harm us even if we were to be
successful in the litigation.  In addition, patent applications filed in foreign
countries are subject to laws,  rules and  procedures  that differ from those of
the United  States.  Therefore,  there can be no assurance  that foreign  patent
applications  related to patents  issued in the United  States  will be granted.
Furthermore,  even if  these  patent  applications  are  granted,  some  foreign
countries provide  significantly  less patent protection than the United States.
In the  absence  of  patent  protection,  and  despite  our  reliance  upon  our
proprietary  confidential  information,  our  competitors  may  be  able  to use
innovations  similar  to those  used by us to design  and  manufacture  products
directly competitive with our products.  In addition,  no assurance can be given
that  others  will not  obtain  patents  that we will need to  license or design
around. To the extent any of our products are covered by third-party patents, we
could require a license under such patents to develop and market our patents.


                                       10


            Despite  our  efforts to  safeguard  and  maintain  our  proprietary
rights,  we may not be  successful  in doing so.  In  addition,  competition  is
intense,   and  there  can  be  no  assurance  that  our  competitors  will  not
independently  develop or patent technologies that are substantially  equivalent
or superior to our technology.  Moreover, in the event of patent litigation,  we
cannot assure you that a court would determine that we were the first creator of
inventions covered by our issued patents or pending patent  applications or that
we were the first to file patent applications for those inventions.  If existing
or future third-party  patents containing broad claims were upheld by the courts
or if we were  found to  infringe  third  party  patents,  we may not be able to
obtain the  required  licenses  from the holders of such  patents on  acceptable
terms,  if at all.  Failure to obtain these  licenses  could cause delays in the
introduction  of our products or  necessitate  costly  attempts to design around
such patents,  or could  foreclose the  development,  manufacture or sale of our
products. We could also incur substantial costs in defending ourselves in patent
infringement  suits  brought by others and in  prosecuting  patent  infringement
suits against infringers.

            We also rely on trade secrets and proprietary  know-how that we seek
to protect, in part, through non-disclosure and confidentiality  agreements with
our  customers,  employees,   consultants,   strategic  partners  and  potential
strategic  partners.  We cannot  assure  you that these  agreements  will not be
breached,  that we would have adequate remedies for any breach or that our trade
secrets  will not  otherwise  become  known  or be  independently  developed  by
competitors.

      WE ARE DEPENDENT ON KEY PERSONNEL AND OUR BUSINESS WOULD SUFFER IF WE FAIL
TO RETAIN THEM.

            We are highly  dependent on certain  members of our  management  and
engineering  staff, and the loss of the services of one or more of these persons
could  adversely  affect us. We are especially  dependent on the services of our
Chairman,  President and Chief Executive Officer, Robert S. Ehrlich. The loss of
Mr.  Ehrlich  could  have a  material  adverse  effect on us. We are party to an
employment  agreement with Mr. Ehrlich,  which  agreement  expires at the end of
2005. We do not have key-man life insurance on Mr. Ehrlich.

      THERE ARE RISKS INVOLVED WITH THE INTERNATIONAL NATURE OF OUR BUSINESS.

            A  significant  portion of our sales are made to  customers  located
outside the U.S.,  primarily in Europe and Asia. In 2000, 2001 and 2002, without
taking account of revenues derived from discontinued  operations,  45%, 49%, and
56%, respectively, of our revenues, including, in the case of 2002, the revenues
of IES and MDT, were derived from sales to customers located outside the U.S. We
expect  that  our  international  customers  will  continue  to  account  for  a
substantial  portion of our revenues in the near future.  Sales to international
customers may be subject to political and economic  risks,  including  political
instability,  currency  controls,  exchange rate  fluctuations,  foreign  taxes,
longer payment cycles and changes in import/export regulations and tariff rates.
In addition,  various forms of protectionist  trade legislation have been and in
the  future  may be  proposed  in the U.S.  and  certain  other  countries.  Any
resulting  changes in current  tariff  structures  or other  trade and  monetary
policies could adversely affect our sales to international customers.

      INVESTORS  SHOULD NOT PURCHASE OUR COMMON  STOCK WITH THE  EXPECTATION  OF
RECEIVING CASH DIVIDENDS.

            We currently intend to retain any future earnings for funding growth
and, as a result,  do not expect to pay any cash  dividends  in the  foreseeable
future.

MARKET-RELATED RISKS

      THE PRICE OF OUR COMMON STOCK IS VOLATILE.

            The market price of our common  stock has been  volatile in the past
and may change rapidly in the future. The following  factors,  among others, may
cause significant volatility in our stock price:

            o     Announcements by us, our competitors or our customers;

            o     The  introduction of new or enhanced  products and services by
                  us or our competitors;

            o     Changes  in  the  perceived   ability  to  commercialize   our
                  technology compared to that of our competitors;

            o     Rumors relating to our competitors or us;

            o     Actual or anticipated  fluctuations in our operating  results;
                  and

            o     General market or economic conditions.

      IF OUR SHARES WERE TO BE DELISTED,  OUR STOCK PRICE MIGHT DECLINE  FURTHER
AND WE MIGHT BE UNABLE TO RAISE ADDITIONAL CAPITAL.

            One of the continued  listing  standards for our stock on the Nasdaq
National  Market is the  maintenance  of a $1.00 bid price.  Our stock price has
periodically  traded below $1.00 in the recent past. If our bid price were to go
and remain below $1.00 for 30 consecutive  business days, Nasdaq could notify us
of our failure to meet the  continued  listing  standards,  after which we would
have 180 calendar  days to correct  such failure or be delisted  from the Nasdaq
National Market.

            Although  we would  have the  opportunity  to appeal  any  potential
delisting,  there  can be no  assurances  that  this  appeal  would be  resolved
favorably.  As a result,  there can be no  assurance  that our common stock will
remain  listed on the Nasdaq  National  Market.  If our common  stock were to be
delisted  from the Nasdaq  National  Market,  we might apply to be listed on the
Nasdaq  SmallCap  market;  however,  there can be no assurance  that we would be
approved  for listing on the Nasdaq  SmallCap  market,  which has the same $1.00
minimum bid and other similar  requirements as the Nasdaq National Market. If we
were to move to the Nasdaq SmallCap  market,  current Nasdaq  regulations  would
give us the  opportunity  to obtain an  additional  180-day  grace period and an
additional  90-day  grace  period  after  that if we meet  certain  net  income,
stockholders' equity or market  capitalization  criteria.  While our stock would
continue to trade on the over-the-counter bulletin board following any delisting
from the Nasdaq,  any such  delisting  of our common stock could have an adverse
effect on the market price of, and the efficiency of the trading market for, our
common stock.  Also, if in the future we were to determine  that we need to seek
additional  equity  capital,  it could have an adverse  effect on our ability to
raise capital in the public equity markets.

            In  addition,  if  we  fail  to  maintain  Nasdaq  listing  for  our
securities,  and no other exclusion from the definition of a "penny stock" under
the Exchange Act is available,  then any broker engaging in a transaction in our
securities  would be  required to provide any  customer  with a risk  disclosure
document,   disclosure  of  market  quotations,   if  any,   disclosure  of  the
compensation  of the  broker-dealer  and its  salesperson in the transaction and
monthly account  statements  showing the market values of our securities held in
the customer's account. The bid and offer quotation and compensation information
must be provided prior to effecting the transaction and must be contained on the
customer's  confirmation.  If brokers  become subject to the "penny stock" rules
when engaging in transactions in our securities,  they would become less willing
to engage in transactions, thereby making it more difficult for our stockholders
to dispose of their shares.


                                       12


      WE ARE SUBJECT TO SIGNIFICANT INFLUENCE BY SOME STOCKHOLDERS THAT MAY HAVE
THE EFFECT OF DELAYING OR PREVENTING A CHANGE IN CONTROL.

            As of January  15,  2004,  our  directors,  executive  officers  and
principal  stockholders and their affiliates (including Leon S. Gross (6.0%) and
Robert  S.  Ehrlich  (3.9%))   collectively  are  deemed   beneficially  to  own
approximately  10.7% of the  outstanding  shares of our common stock,  including
options  exercisable  within 60 days of January  15,  2004.  As a result,  these
stockholders are able to exercise  significant  influence over matters requiring
stockholder  approval,  including  the  election of  directors  and  approval of
significant  corporate  transactions.  This  concentration of ownership may also
have the effect of delaying,  preventing or  discouraging a change in control of
Arotech.

            Pursuant to a voting rights  agreement  dated September 30, 1996, as
amended,  between  Leon S.  Gross,  Robert S.  Ehrlich,  Yehuda  Harats  and us,
Lawrence M. Miller, Mr. Gross's advisor, is entitled to be nominated to serve on
our  board of  directors  so long as Mr.  Gross,  his  heirs or  assigns  retain
beneficial  ownership of at least 1,375,000 shares of common stock. In addition,
under the voting  rights  agreement,  Mr.  Gross and Messrs.  Ehrlich and Harats
agreed to vote and take all necessary action so that Messrs. Ehrlich, Harats and
Miller  shall  serve as members of the board of  directors  until the earlier of
December 28, 2004 or our fifth annual meeting of stockholders after December 28,
1999. Mr. Harats  resigned as a director in 2002;  however,  we believe that Mr.
Harats must continue to comply with the terms of this  agreement.

      A  SUBSTANTIAL  NUMBER OF OUR SHARES ARE  AVAILABLE FOR SALE IN THE PUBLIC
MARKET AND SALES OF THOSE SHARES COULD ADVERSELY AFFECT OUR STOCK PRICE.

            Sales of a  substantial  number of shares of common  stock  into the
public market,  or the perception that those sales could occur,  could adversely
affect our stock price or could impair our ability to obtain capital  through an
offering of equity securities.  As of January 15, 2004, we had 59,096,069 shares
of common  stock  issued  and  outstanding.  Of these  shares,  most are  freely
transferable  without  restriction  under  the  Securities  Act of  1933,  and a
substantial  portion of the  remaining  shares may be sold subject to the volume
restrictions,  manner-of-sale  provisions and other conditions of Rule 144 under
the Securities Act of 1933.

            In connection  with a stock purchase  agreement  dated September 30,
1996 between Leon S. Gross and us, we also  entered into a  registration  rights
agreement with Mr. Gross dated  September 30, 1996,  setting forth  registration
rights  with  respect  to the  shares of  common  stock  issued to Mr.  Gross in
connection with the offering. These rights include the right to make two demands
for the  registration  of the shares of our common stock owned by Mr. Gross.  In
addition,  Mr. Gross was granted unlimited rights to "piggyback" on registration
statements  that we file for the sale of our common stock.  Mr. Gross  presently
owns 3,488,534 shares, of which 1,538,462 have never been registered.

      EXERCISE OF OUR WARRANTS,  OPTIONS AND  CONVERTIBLE  DEBT COULD  ADVERSELY
AFFECT OUR STOCK PRICE AND WILL BE DILUTIVE.

            As of January 15, 2004, there were outstanding  warrants to purchase
a total of 18,852,157  shares of our common stock at a weighted average exercise
price of $1.87 per share, options to purchase a total of 8,860,822 shares of our
common stock at a weighted  average  exercise price of $1.48 per share, of which
6,210,217 were vested,  at a weighted average exercise price of $1.68 per share,
and outstanding  debentures  convertible into a total of 5,203,149 shares of our
common stock at a weighted average conversion price of $1.39 per share.  Holders
of our options,  warrants and convertible debt will probably exercise or convert
them only at a time  when the price of our  common  stock is higher  than  their
respective  exercise or conversion  prices.  Accordingly,  we may be required to
issue shares of our common stock at a price  substantially lower than the market
price of our stock. This could adversely affect our stock price. In addition, if
and when these  shares  are  issued,  the  percentage  of our common  stock that
existing stockholders own will be diluted.


                                       13


      OUR  CERTIFICATE  OF  INCORPORATION  AND BYLAWS AND  DELAWARE  LAW CONTAIN
PROVISIONS THAT COULD DISCOURAGE A TAKEOVER.

            Provisions of our amended and restated  certificate of incorporation
may have the effect of making it more difficult for a third party to acquire, or
of discouraging a third party from  attempting to acquire,  control of us. These
provisions could limit the price that certain  investors might be willing to pay
in the future for shares of our common stock. These provisions:

            o     divide  our board of  directors  into  three  classes  serving
                  staggered three-year terms;

            o     only permit removal of directors by stockholders  "for cause,"
                  and  require  the  affirmative  vote  of at  least  85% of the
                  outstanding common stock to so remove; and

            o     allow us to issue  preferred stock without any vote or further
                  action by the stockholders.

                  The  classification  system  of  electing  directors  and  the
removal  provision  may tend to  discourage a  third-party  from making a tender
offer or  otherwise  attempting  to obtain  control of us and may  maintain  the
incumbency  of our board of  directors,  as the  classification  of the board of
directors  increases the  difficulty  of replacing a majority of the  directors.
These provisions may have the effect of deferring  hostile  takeovers,  delaying
changes  in our  control  or  management,  or may  make  it more  difficult  for
stockholders to take certain  corporate  actions.  The amendment of any of these
provisions  would require approval by holders of at least 85% of the outstanding
common stock.

ISRAEL-RELATED RISKS

      A  SIGNIFICANT  PORTION OF OUR  OPERATIONS  TAKES PLACE IN ISRAEL,  AND WE
COULD BE ADVERSELY AFFECTED BY THE ECONOMIC,  POLITICAL AND MILITARY  CONDITIONS
IN THAT REGION.

            The offices and facilities of two of our subsidiaries,  EFL and MDT,
are located in Israel (in Beit Shemesh and Lod, respectively,  both of which are
within  Israel's  pre-1967  borders).  We conduct some research and  development
activities  through EFL, and most of our senior  management  is located at EFL's
facilities.  Although we expect that most of our sales will be made to customers
outside Israel, we are nonetheless directly affected by economic,  political and
military  conditions  in  that  country.   Accordingly,  any  major  hostilities
involving  Israel or the interruption or curtailment of trade between Israel and
its  present  trading  partners  could  have a  material  adverse  effect on our
operations.  Since the establishment of the State of Israel in 1948, a number of
armed  conflicts  have taken place between  Israel and its Arab  neighbors and a
state of  hostility,  varying in degree and  intensity,  has led to security and
economic problems for Israel.

            Historically,  Arab  states  have  boycotted  any direct  trade with
Israel and to varying  degrees have  imposed a secondary  boycott on any company
carrying on trade with or doing  business in Israel.  Although in October  1994,
the states  comprising the Gulf  Cooperation  Council (Saudi Arabia,  the United
Arab Emirates,  Kuwait,  Dubai,  Bahrain and Oman)  announced that they would no
longer adhere to the secondary  boycott against  Israel,  and Israel has entered
into  certain   agreements  with  Egypt,   Jordan,   the  Palestine   Liberation
Organization  and the  Palestinian  Authority,  Israel has not entered  into any
peace arrangement with Syria or Lebanon.  Moreover,  since September 2000, there
has  been  a  significant   deterioration  in  Israel's  relationship  with  the
Palestinian  Authority,  and a  significant  increase  in terror  and  violence.
Efforts to resolve the problem have failed to result in an  agreeable  solution.
Continued  hostilities  between  the  Palestinian  community  and Israel and any
failure  to  settle  the  conflict  may have a  material  adverse  effect on our
business and us. Moreover,  the current political and security  situation in the
region has already had an adverse effect on the economy of Israel, which in turn
may have an adverse effect on us.

            Many of our  employees  are  currently  obligated to perform  annual
reserve  duty in the Israel  Defense  Forces and are subject to being called for
active  military duty at any time. No assessment  can be made of the full impact
of  such   requirements   on  us  in  the  future,   particularly  if  emergency
circumstances occur, and no prediction can be made as to the effect on us of any
expansion of these obligations.  However,  further  deterioration of hostilities
with the  Palestinian  community  into a full-scale  conflict might require more
widespread military reserve service by some of our employees, which could have a
material adverse effect on our business.


                                       14


      SERVICE OF PROCESS  AND  ENFORCEMENT  OF CIVIL  LIABILITIES  ON US AND OUR
OFFICERS MAY BE DIFFICULT TO OBTAIN.

            We are organized under the laws of the State of Delaware and will be
subject to service of process in the United States.  However,  approximately 49%
of our assets are located  outside the United  States.  In addition,  two of our
directors  and all of our  executive  officers  are  residents  of Israel  and a
portion of the assets of such  directors  and  executive  officers  are  located
outside the United States.

            There is doubt as to the  enforceability  of civil liabilities under
the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934,
as amended,  in  original  actions  instituted  in Israel.  However,  subject to
certain time limitations and other conditions,  Israeli courts may enforce final
judgments  of United  States  courts for  liquidated  amounts in civil  matters,
including judgments based upon the civil liability  provisions of the Securities
Act and the Exchange  Act. As a result,  it may not be possible for investors to
enforce or effect service of process upon these directors and executive officers
or to judgments of U.S. courts predicated upon the civil liability provisions of
U.S.  laws  against our  assets,  as well as the assets of these  directors  and
executive officers.  In addition,  awards of punitive damages in actions brought
in the U.S. or elsewhere may be unenforceable in Israel.

      OUR GRANTS FROM THE ISRAELI GOVERNMENT IMPOSE CERTAIN RESTRICTIONS ON US.

            Between 1992 and 2001, our Israeli subsidiary, EFL, received funding
from the Office of the Chief  Scientist  of the Israel  Ministry of Industry and
Trade relating to the development of our Zinc-Air battery products,  such as our
electric vehicle and our batteries and chargers for consumer  products.  Between
1998 and 2000, we have also  received  funds from the  Israeli-U.S.  Bi-National
Industrial Research and Development (BIRD) Foundation.  Through the end of 2002,
we had received an aggregate of $9.9 million (net of royalties paid) from grants
from the Chief  Scientist and $772,000  from grants from BIRD.  The funding from
the Chief  Scientist  prohibits  the  transfer  or license of  know-how  and the
manufacture  of resulting  products  outside of Israel without the permission of
the Chief  Scientist.  Although  we believe  that the Chief  Scientist  does not
unreasonably  withhold this permission if the request is based upon commercially
justified  circumstances and any royalty  obligations to the Chief Scientist are
sufficiently  assured,  the matter is solely within the  discretion of the Chief
Scientist,  and we  cannot be sure that such  consent,  if  requested,  would be
granted upon terms  satisfactory to us or granted at all.  Without such consent,
we would be  unable to  manufacture  any  products  developed  by this  research
outside  of  Israel,  even  if it  would  be  less  expensive  for  us to do so.
Additionally,  current  regulations  require  that,  in the case of the approved
transfer of manufacturing  rights out of Israel, the maximum amount to be repaid
through  royalty  payments  would be  increased  to between 120% and 300% of the
amount  granted,  depending on the extent of the  manufacturing  to be conducted
outside  of  Israel,  and that an  increased  royalty  rate of up to 5% would be
applied.  These  restrictions  could adversely affect our potential revenues and
net income from the sale of such products.

      EXCHANGE RATE FLUCTUATIONS BETWEEN THE U.S. DOLLAR AND THE ISRAELI NIS MAY
NEGATIVELY AFFECT OUR EARNINGS.

            Although a  substantial  majority of our revenues and a  substantial
portion of our expenses are denominated in U.S. dollars,  a significant  portion
of our costs, including personnel and  facilities-related  expenses, is incurred
in New  Israeli  Shekels  (NIS).  Inflation  in Israel  will have the  effect of
increasing the dollar cost of our operations in Israel, unless it is offset on a
timely basis by a devaluation of the NIS relative to the dollar.

      SOME OF OUR AGREEMENTS ARE GOVERNED BY ISRAELI LAW.

            Israeli law governs both our  agreement  with IES and our  agreement
with MDT, as well as certain other  agreements,  such as our lease agreements on
our  subsidiaries'  premises  in Israel.  While  Israeli  law differs in certain
respects from American law, we do not believe that these differences  materially
adversely affect our rights or remedies under these agreements.

the  information in this  prospectus was accurate on the date of the front cover
of  this  prospectus  only.  Our  business,   financial  condition,  results  of
operations and prospects may have changed since that date.

                               ABOUT THE OFFERING

            We are  registering  the resale of our common  stock by the  selling
stockholders.  The selling  stockholders  and the specific number of shares that
they each may resell  through this  prospectus are listed on page 19. The shares
offered for resale by this prospectus include the following:

            >     175,000  shares of common  stock owned by Yehuda  Harats,  our
                  former CEO;

            >     4,137,932 shares of common stock that may be acquired upon the
                  conversion of currently outstanding debentures; and

            >     13,627,418  shares of common  stock that may be acquired  upon
                  the exercise of currently outstanding warrants.

                                 USE OF PROCEEDS

            All net proceeds from the sale of the shares of common stock offered
hereunder by the selling  stockholders will go to the stockholder who offers and
sells them.  We will not receive any of the proceeds from the offering of shares
of our common stock by the selling  stockholders.  Certain of the shares covered
hereby are issuable upon the exercise of warrants.  If these  warrants are fully
exercised, we will receive gross proceeds of $25,431,041. Such proceeds would be
added to working capital and used for general corporate purposes.

                                       16


      SHARES ISSUABLE IN CONNECTION WITH OUR SALE OF CONVERTIBLE DEBENTURES

            Pursuant  to the  terms of a  Securities  Purchase  Agreement  dated
September 30, 2003 (the "Purchase Agreement") by and between Arotech Corporation
and six  institutional  investors (the  "Investors"),  we issued and sold to the
Investors  (i)  an  aggregate  principal  amount  of  $5,000,000  in 8%  secured
convertible  debentures  due  September  30,  2006 (the  "Initial  Debentures"),
convertible  into shares of our common stock at a conversion  price of $1.15 per
share, and (ii) three-year  warrants to purchase up to an aggregate of 1,250,000
shares of our common  stock (the  "Initial  Warrants")  at an exercise  price of
$1.4375  per share.  The  Debentures  earn  interest  at a rate of 8% per annum,
payable in cash or stock quarterly.  We are not presently registering any shares
for use in  connection  with  interest  payments.  We  completed  the process of
registering the shares  issuable in connection  with the Initial  Debentures and
the Initial Warrants on December 5, 2003.

            The Investors also have the right,  at their option,  to purchase up
to an additional  $6,000,000 in debentures  (the  "Additional  Debentures"  and,
together with the Initial Debentures,  the "Debentures") convertible into shares
of our common  stock at a  conversion  price of $1.45 per share,  and to receive
warrants to purchase up to an aggregate of 1,500,000  shares of our common stock
(the  "Additional  Warrants")  at an exercise  price of $1.8125  per share.  The
Investors  exercised this option in December 2003,  pursuant to an Amendment and
Exercise  Agreement  dated  December 10, 2003 that also granted to the Investors
incentive  warrants to purchase up to an aggregate  of  1,038,000  shares of our
common stock (the "Incentive  Warrants" and,  together with the Initial Warrants
and the Additional  Warrants,  the "Warrants") at an exercise price of $2.20 per
share.  We are presently  registering the shares issuable in connection with the
Additional Debentures, the Additional Warrants and the Incentive Warrants.

            Under the  terms of the  Purchase  Agreement,  we have  granted  the
Investors  (i) a first  position  security  interest  in the  stock of MDT Armor
Corporation,  the assets of our IES Interactive Training,  Inc. subsidiary,  the
stock of our subsidiaries other than IES Interactive  Training,  Inc. and M.D.T.
Protective  Industries,  Ltd.,  and in any  assets  that we  acquire  in  future
Acquisitions (as defined in the Purchase Agreement),  and (ii) a second position
security  interest in the stock of our  subsidiaries  I.E.S.  Defense  Services,
Inc., IES Interactive  Training,  Inc. and M.D.T.  Protective  Industries,  Ltd.
(junior to the security interest of I.E.S.  Electronics  Industries,  Ltd.), all
pursuant to the terms of separate  security  agreements filed as exhibits to the
Form 8-K that we filed with the Securities and Exchange Commission on October 3,
2003. We also committed  ourselves to certain affirmative and negative covenants
customary in agreements of this kind.

            We entered into a  Registration  Rights  Agreement with such selling
stockholders under the Securities Purchase Agreement pursuant to which we agreed
to register our shares of common stock issuable to the debenture holders. We are
bearing the expenses of this registration.

            The terms of the debentures and the warrants whose underlying shares
of  common  stock  are  included  for  resale  under  this  prospectus  prohibit
conversion  of the  debentures  or exercise  of the  warrants to the extent that
conversion  of the  debentures  or exercise of the warrants  would result in the
holder, together with its affiliates, beneficially owning in excess of 4.999% of
our outstanding  shares of common stock,  and to the extent that exercise of the
warrants would result in the holder, together with its affiliates,  beneficially
owning in excess of 4.999%  of our  outstanding  shares of common  stock.  These
limitations  do not preclude a holder from  converting or exercising a debenture
or warrant, respectively, and selling shares underlying the debenture or warrant
in  stages  over time  where  each  stage  does not  cause  the  holder  and its
affiliates to beneficially own shares in excess of the limitation  amounts.  The
footnotes to the table describe  beneficial  ownership  adjustments  required by
these limitations, if any.

            In addition to the above  restrictions,  the outstanding  debentures
and  warrants  each contain a provision  which  precluded  us from  issuing,  in
connection with the  transactions  described  below, and at prices less than the
greater of book or market value of our common  stock,  a number of shares of our
common stock which,  in the  aggregate  for such  transactions,  would exceed in
excess of 19.99% of our common stock  outstanding  as of the date we consummated
such  transactions.  The foregoing  limitation  will cease to apply in the event
that  we  obtain,  prior  to  any  such  prohibited  issuance,  approval  of our
stockholders  under applicable  Nasdaq  Marketplace Rules to issue in connection

      SHARES ISSUABLE IN CONNECTION WITH OUTSTANDING  WARRANTS HELD BY INVESTORS
IN OUR MAY 2001 OFFERING

            We issued  warrants  to  certain  investors  in May 2001  ("May 2001
Warrants") to purchase  2,696,971 shares of our common stock at a purchase price
of $3.22 per share. In June 2003, in order to improve our cash situation and our
shareholders'  equity,  we adjusted the  purchase  price of 1,357,677 of the May
2001  Warrants to $0.82 per share in exchange  for  immediate  exercise of these
warrants,  and issued to the holders of these exercised warrants new warrants to
purchase a total of 905,052  shares of our common  stock at a purchase  price of
$1.45 per  share  (the  "June  2003  Warrants").  The June  2003  Warrants  were
originally  exercisable at any time from and after December 31, 2003 to June 30,
2008;  however,  in September 2003, the exercise period of 638,385 of these June
2003 Warrants was adjusted to make them  exercisable  at any time from and after
December 31, 2004 to June 30, 2009.

            In  addition,  with  respect  to  an  additional  387,879  May  2001
Warrants,  in December 2003 we adjusted the purchase price to $1.60 per share in
exchange for immediate exercise of these warrants,  and issued to the holders of
these  exercised  warrants new warrants to purchase a total of 193,940 shares of
our common  stock at a purchase  price of $2.25 per share  (the  "December  2003
Warrants").

            Additionally, in October 2003 we granted to three of these investors
additional  new  warrants  to  purchase a total of 150,000  shares of our common
stock at a purchase price of $1.20 per share (the "Supplementary Warrants").

            We are now registering the shares underlying all of these warrants.

            We are bearing the expenses of this registration.

            The  June  2003  Warrants,   the  December  2003  Warrants  and  the
Supplementary   Warrants  were  issued  in  reliance  upon  the  exemption  from
registration  provided by Section 4(2) of the Securities Act as  transactions by
an issuer not involving a public offering.

      SHARES ISSUABLE IN CONNECTION WITH OUTSTANDING  WARRANTS HELD BY INVESTORS
IN OUR JANUARY 2004 OFFERING

            Pursuant  to the  terms of a  Securities  Purchase  Agreement  dated
January  7,  2004 (the  "SPA")  by and  between  Arotech  Corporation  and eight
institutional  investors (the "2004 Investors"),  we issued and sold to the 2004
Investors  (i) an aggregate  of  9,840,426  shares of our common stock (off of a
shelf  registration  statement that was declared effective on December 5, 2003),
and (ii) three-year  warrants to purchase up to an aggregate of 9,840,426 shares
of our common  stock (the "2004  Warrants")  at an  exercise  price of $1.88 per
share.  A copy of the SPA was filed as an  exhibit to the Form 8-K that we filed
with the Securities and Exchange Commission on January 9, 2004.

            We also entered into a Registration  Rights  Agreement with the 2004
Investors  under the SPA  pursuant to which we agreed to register  our shares of
common stock issuable to upon exercise of the 2004 Warrants.  We are bearing the
expenses of this registration.


                                       18


            The terms of the 2004  Warrants  whose  underlying  shares of common
stock are  included for resale under this  prospectus  prohibit  exercise of the
2004 Warrants to the extent that  exercise of the 2004 Warrants  would result in
the  holder,  together  with its  affiliates,  beneficially  owning in excess of
4.999% of our  outstanding  shares of common  stock.  These  limitations  do not
preclude a holder from  exercising a warrant and selling  shares  underlying the
warrant  in stages  over time where each stage does not cause the holder and its
affiliates to beneficially own shares in excess of the limitation  amounts.  The
footnotes to the table describe  beneficial  ownership  adjustments  required by
these limitations, if any.

            The 2004  Warrants  issued  to the 2004  Investors  were  issued  in
reliance upon the exemption  from  registration  provided by Section 4(2) of the
Securities Act as transactions by an issuer not involving a public offering.

      SELLING STOCKHOLDER TABLE

            The  following  table   identifies  the  selling   stockholders  and
indicates (i) the nature of any position,  office or other material relationship
that each  selling  stockholder  has had with us during the past three years (or
any of our  predecessors  or  affiliates)  and (ii) the  number of shares of our
common stock owned by the selling stockholder prior to the offering,  the number
of shares to be offered for the selling  stockholder's account and the number of
shares  and  percentage  of  outstanding  shares  to be  owned  by  the  selling
stockholder after completion of the offering, all as of January 15, 2004.

            Beneficial  ownership is determined  in  accordance  with Rule 13d-3
promulgated by the Securities and Exchange  Commission,  and generally  includes
voting or investment  power with respect to  securities.  Except as indicated in
the  footnotes to the table,  we believe each holder  possesses  sole voting and
investment power with respect to all of the shares of common stock owned by that
holder. In computing the number of shares beneficially owned by a holder and the
percentage  ownership of that holder,  shares of common stock subject to options
or  warrants or  underlying  debentures  held by that holder that are  currently
exercisable  or convertible  or are  exercisable  or convertible  within 60 days
after the date of the table are deemed outstanding.  Those shares,  however, are
not deemed outstanding for the purpose of computing the percentage  ownership of
any other person or group.

                              PLAN OF DISTRIBUTION

            The  selling  stockholders,  which as used herein  includes  donees,
pledgees, assignees and successors-in-interest selling shares of common stock or
interests in shares of common stock received  after the date of this  prospectus
from a selling stockholder as a gift, pledge,  partnership distribution or other
transfer,  may,  from  time to time,  sell any or all of their  shares of common
stock or interests in shares of common  stock on any stock  exchange,  market or
trading  facility  on which the shares  are  traded or in private  transactions.
These sales may be at fixed or negotiated prices.  The selling  stockholders may
use any one or more of the following methods when selling shares:

            >     ordinary brokerage  transactions and transactions in which the
                  broker-dealer solicits purchasers;

            >     block trades in which the  broker-dealer  will attempt to sell
                  the shares as agent but may  position  and resell a portion of
                  the block as principal to facilitate the transaction;


                                       22


            >     purchases by a  broker-dealer  as principal  and resale by the
                  broker-dealer for its account;

            >     an exchange  distribution  in accordance with the rules of the
                  applicable exchange;

            >     privately negotiated transactions;

            >     short sales;

            >     through the writing or  settlement  of option or other hedging
                  transactions,   whether   through  an  options   exchange   or
                  otherwise;

            >     broker-dealers may agree with the selling stockholders to sell
                  a specified  number of such shares at a  stipulated  price per
                  share;

            >     a combination of any such methods of sale; and

            >     any other method permitted pursuant to applicable law.

            The selling  shareholders may enter into hedging  transactions  with
third parties,  which may in turn engage in short sales of the common stock into
which the debentures are  convertible or warrants are  exercisable in the course
of hedging the positions they assume.  The selling  shareholders  may also enter
into short positions or options or other derivative transactions relating to the
common  stock  into  which  the  debentures  are  convertible  or  warrants  are
exercisable,  or interests in the common stock, and deliver the common stock, or
interests  in the  common  stock,  to close  out  their  short,  option or other
positions  or  otherwise  settle  short  sales or  options  or other  derivative
transactions,  or loan or pledge the common stock into which the  debentures are
convertible or warrants are  exercisable,  or interests in the common stock,  to
third parties that in turn may dispose of these securities.

            The selling  stockholders  may also sell shares under Rule 144 under
the Securities Act, if available, rather than under this prospectus.

            Broker-dealers  engaged by the selling  stockholders may arrange for
other  brokers-dealers  to  participate  in sales.  Broker-dealers  may  receive
commissions or discounts from the selling stockholders (or, if any broker-dealer
acts as agent for the purchaser of shares,  from the purchaser) in amounts to be
negotiated.  These commissions and discounts may exceed what is customary in the
types of transactions involved.

            The  selling  stockholders  may from time to time  pledge or grant a
security  interest in some or all of the shares of our common  stock or warrants
owned  by  them  and,  if they  default  in the  performance  of  their  secured
obligations,  the  pledgees or secured  parties may offer and sell the shares of
common stock from time to time under this  prospectus,  or under an amendment to
this  prospectus  under Rule  424(b)(3)  or other  applicable  provision  of the
Securities Act of 1933 amending the list of selling  stockholders to include the
pledgee,  transferee  or other  successors  in interest as selling  stockholders
under this prospectus.

            The  selling  stockholders  also may  transfer  the shares of common
stock in other circumstances,  in which case the transferees,  pledgees or other
successors  in interest  will be the selling  beneficial  owners for purposes of
this prospectus.

            The selling  stockholders and any  broker-dealers or agents that are
involved  in selling  the shares may be deemed to be  "underwriters"  within the
meaning of the Securities Act in connection with such sales. In such event,  any
commissions  received  by such  broker-dealers  or agents  and any profit on the
resale  of the  shares  purchased  by  them  may be  deemed  to be  underwriting
commissions or discounts under the Securities Act. The selling stockholders have
advised us that they have acquired  their  securities in the ordinary  course of
business  and they  have not  entered  into any  agreements,  understandings  or
arrangements with any underwriters or broker-dealers regarding the sale of their
shares of common  stock,  nor is there an  underwriter  or  coordinating  broker
acting in  connection  with a  proposed  sale of  shares of common  stock by any
selling stockholder.


                                       23


            We are  required  to pay  all  fees  and  expenses  incident  to the

special  counsel to  certain  of the  selling  stockholders.  We have  agreed to
indemnify the selling stockholders against certain losses,  claims,  damages and
liabilities, including liabilities under the Securities Act.

            The selling stockholders are subject to applicable provisions of the
Exchange Act and the Commission's rules and regulations, including Regulation M,
which  provisions  may limit the timing of purchases  and sales of the shares by
the selling  stockholders.  We will make copies of this prospectus  available to
the selling stockholders and have informed them of the need to deliver copies of
this prospectus to purchasers at or prior to the time of any sale of the shares.

            In  order  to  comply  with  certain  states'  securities  laws,  if
applicable,  the selling stockholders may sell the shares in those jurisdictions
only through  registered or licensed  brokers or dealers.  In certain states the
selling  stockholders  may not sell the  shares  unless  the  shares  have  been
registered  or qualified  for sale in such state,  or unless an  exemption  from
registration or qualification is available and is obtained.

            Our common stock is currently  traded on the Nasdaq  National Market
under the symbol "ARTX."

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

            Our  authorized  capital  stock  consists of  100,000,000  shares of
common stock par value $.01 per share,  and 1,000,000 shares of preferred stock,
par value $.01 per share.  As of January 15, 2004,  59,096,069  shares of common
stock were issued and  outstanding,  555,333 shares of common stock were held as
treasury shares, and no shares of preferred stock were issued and outstanding.

            The additional shares of our authorized stock available for issuance
might be issued at times and under circumstances so as to have a dilutive effect
on earnings  per share and on the equity  ownership of the holders of our common
stock. The ability of our board of directors to issue additional shares of stock
could enhance the board's ability to negotiate on behalf of the  stockholders in
a  takeover   situation  but  could  also  be  used  by  the  board  to  make  a
change-in-control more difficult,  thereby denying stockholders the potential to
sell their shares at a premium and entrenching current management. The following
description is a summary of the material  provisions of our capital  stock.  You
should  refer to our amended  and  restated  certificate  of  incorporation,  as
amended, and bylaws for additional information.

COMMON STOCK

            The holders of common  stock are entitled to one vote for each share
held of record on all matters  submitted  to a vote of  stockholders.  Except as
required  under  Delaware law or the rules of the Nasdaq  National  Market,  the
rights  of  stockholders  may  not be  modified  otherwise  than  by a vote of a
majority or more of the shares  outstanding.  Subject to preferences that may be
applicable to any outstanding  shares of preferred  stock, the holders of common
stock are  entitled to receive  ratably any  dividends as may be declared by the
board of directors out of funds legally  available for the payment of dividends.
In the event of our  liquidation,  dissolution  or winding  up,  the  holders of
common  stock are  entitled  to share  ratably in all  assets,  subject to prior
distribution rights of the preferred stock, if any, then outstanding. Holders of
common stock have no  preemptive  rights or rights to convert their common stock
into any other  securities.  There are no redemption or sinking fund  provisions
applicable to the common stock. All outstanding shares of common stock are fully
paid and non-assessable.

PREFERRED STOCK

            Our board of directors has the authority, within the limitations and
restrictions stated in our amended and restated certificate of incorporation and
without  shareholder  approval,  to provide by  resolution  for the  issuance of
shares of preferred  stock, and to fix the rights,  preferences,  privileges and
restrictions  thereof,  including  dividend rights,  conversion  rights,  voting
rights,  terms of  redemption,  liquidation  preference and the number of shares
constituting  any series of the  designation  of such  series.  The  issuance of
preferred  stock  could have the effect of  decreasing  the market  price of the
common stock,  impeding or delaying a possible takeover and adversely  affecting
the voting and other rights of the holders of our common stock.  At present,  we
have no plans to issue preferred stock.


                                       24


STOCK OPTIONS

            As of January 15,  2004,  options to  purchase a total of  8,860,822
shares of common stock at a weighted  average  exercise price of $1.48 per share
were outstanding,  6,210,217 of which were vested and exercisable within 60 days
of the date of this  prospectus,  at a weighted  average exercise price of $1.68
per share.

WARRANTS

            As of January 15, 2004, there were outstanding  warrants to purchase
a total of  18,852,157  shares of common  stock at a weighted  average  exercise
price of $1.87 per share.

DEBENTURES

            As  of  January  15,  2004,   there  were   outstanding   debentures
convertible  into a total of  5,203,149  shares  of common  stock at a  weighted
average conversion price of $1.39 per share.

CERTAIN CHARTER PROVISIONS

            Provisions of our amended and restated  certificate of incorporation
may have the effect of making it more difficult for a third party to acquire, or
of discouraging a third party from  attempting to acquire,  control of us. These
provisions could limit the price that certain  investors might be willing to pay
in the future for shares of our common stock. These provisions:

            o     divide  our board of  directors  into  three  classes  serving
                  staggered three-year terms;

            o     only permit removal of directors by stockholders  "for cause,"
                  and  require  the  affirmative  vote  of at  least  85% of the
                  outstanding common stock to so remove; and

            o     allow us to issue  preferred stock without any vote or further
                  action by the stockholders.

            The  classification  system of  electing  directors  and the removal
provision  may tend to  discourage a  third-party  from making a tender offer or
otherwise  attempting to obtain control of us and may maintain the incumbency of
our  board  of  directors,  as the  classification  of the  board  of  directors
increases  the  difficulty  of  replacing  a majority  of the  directors.  These
provisions may have the effect of deferring hostile takeovers,  delaying changes
in our control or management,  or may make it more difficult for stockholders to
take certain corporate  actions.  The amendment of any of these provisions would
require approval by holders of at least 85% of the outstanding common stock.

                      DESCRIPTION OF COMMON STOCK WARRANTS

            Each warrant  entitles the holder to purchase,  at an exercise price
specified  in the  warrant,  one  share of our  common  stock.  The  warrant  is
exercisable  by the holder at any time and will expire on the  expiration  dates
set forth in the respective warrants and described under "Selling Stockholders,"
above.

            The warrants are generally exercisable by the holder, in whole or in
part,  by  surrender to us of the warrant,  together  with a completed  exercise
agreement,  and payment by the holder of the aggregate  exercise  price in cash,
or, in  limited  circumstances  with  respect to  certain  of the  warrants,  by
effecting a cashless exercise. Upon any exercise of the warrant, we will forward
to the holder,  as soon as  practicable,  but not exceeding  three business days
after proper exercise, a certificate representing the number of shares of common
stock purchased upon such exercise.  If less than all of the shares  represented
by the warrant are  purchased,  we will also deliver to the holder a new warrant
representing  the right to purchase the remaining  shares.  The shares of common
stock  purchased  by the holder upon  exercise of the warrant  will be deemed to
have  been  issued  as of the  close of  business  on the date  the  warrant  is
surrendered to us as described above.


                                       25


            The exercise  price  payable and number of shares  purchasable  upon
exercise of a warrant will  generally be adjusted to prevent the dilution of the
holder's beneficial interest in the common stock in the event we:

            >     declare or pay a dividend in shares of common  stock or make a
                  distribution  of  shares  of common  stock to  holders  of our
                  outstanding common stock;

            >     subdivide or combine our common stock; or

            >     issue shares of our capital stock in any  reclassification  of
                  our common stock.

            Except as described  above,  a holder of a warrant will not have any
of the rights of a holder of common  stock  before the common stock is purchased
upon  exercise of the warrant.  Therefore,  before a warrant is  exercised,  the
holder of the warrant will not be entitled to receive any  dividend  payments or
exercise any voting or other rights  associated  with the shares of common stock
which may be purchased when the warrant is exercised.

                                  LEGAL MATTERS

            Lowenstein  Sandler  PC,  Roseland,  New  Jersey  will pass upon the
validity of the shares of common stock offered by this prospectus for us.

Item 15. Indemnification of Directors and Officers

            Arotech Corporation is a Delaware corporation.  Section 102(b)(7) of
the Delaware  General  Corporation Law (the "DGCL") enables a corporation in its
original  certificate of incorporation  or an amendment  thereto to eliminate or
limit  the  personal   liability  of  a  director  to  the  corporation  or  its
stockholders  for monetary  damages for violations of the  director's  fiduciary
duty,  except  (i) for any  breach  of the  director's  duty of  loyalty  to the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which  involve  intentional  misconduct  or a knowing  violation  of law,  (iii)
pursuant to Section 174 of the DGCL  (providing  for  liability of directors for
unlawful  payment of dividends or unlawful stock  purchases or  redemptions)  or
(iv) for any  transaction  from which a director  derived an  improper  personal
benefit.  The  Company's  Amended  and  Restated  Certificate  of  Incorporation
("Certificate of Incorporation") and By-Laws contain provisions  eliminating the
liability of directors to the extent permitted by the DGCL.

            Section 145 of the DGCL provides  that a  corporation  may indemnify
any  person  who was or is a party  or is  threatened  to be made a party to any
threatened,  pending or completed  action,  suit or  proceeding,  whether civil,
criminal  or  investigative  (other  than an  action  by or in the  right of the
corporation)  by  reason  of the  fact  that he is or was a  director,  officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director,  officer,  employee or agent of another  corporation,
partnership,   joint  venture,  trust  or  other  enterprise,  against  expenses
(including  attorneys'  fees),  judgments,  fines and amounts paid in settlement
actually and reasonably  incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he  reasonably  believed to
be in or not opposed to the best interests of the corporation, and, with respect
to any criminal  action or  proceeding,  had no reasonable  cause to believe his
conduct was unlawful.  Section 145 further provides that a corporation similarly
may indemnify any such person serving in any such capacity who was or is a party
or is  threatened  to be made a party to any  threatened,  pending or  completed
action or suit by or in the right of the corporation to procure  judgment in its
favor,  against expenses actually and reasonably incurred in connection with the
defense or  settlement of such action or suit if he acted in good faith and in a
manner he reasonably  believed to be in or not opposed to the best  interests of
the corporation and except that no  indemnification  shall be made in respect of
any claim,  issue or matter as to which such person shall have been  adjudged to
be liable to the  corporation  unless and only to the extent  that the  Delaware
Court of  Chancery  or such other court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability but
in view of all  the  circumstances  of the  case,  such  person  is  fairly  and
reasonably  entitled to indemnity for such expenses  which the Court of Chancery
or such other court shall deem proper.

            Article 10 of the Company's  Certificate of  Incorporation  provides
that, to the fullest extent permitted by the DGCL, the Company's directors shall
not be liable to the Company or its  stockholders  for monetary  damages for any
breach of fiduciary duty as a director.

            Article 11 of the Company's  Certificate of  Incorporation  provides
that the  Company  shall,  to the  maximum  extent  permitted  under  the  DGCL,
indemnify  any person who was or is made a party or is  threatened  to be made a
party to any threatened, pending or completed action, suit, proceeding or claim,
whether civil, criminal,  administrative or investigative, by reason of the fact
that such  person is or was or has  agreed to be a  director  or  officer of the
Company or while a director  or officer is or was  serving at the request of the
Company as a director,  officer,  partner,  trustee,  employee,  or agent of any
corporation,  partnership,  joint venture, trust or other enterprise,  including
service with respect to employee  benefit  plans,  against  expenses  (including
attorney's  fees),  judgments,  fines,  penalties and amounts paid in settlement
incurred in connection with the investigation,  preparation to defend or defense
of such action, suit, proceeding or claim.


                                      II-1


            The Company also maintains directors' and officers' insurance.

            For the  undertaking  with respect to  indemnification,  see Item 17
herein.

Item 17. Undertakings

The undersigned Registrant hereby undertakes:

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

                  (a) To include any prospectus required by Section 10(a)(3) of
            the Securities Act of 1933,

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

                  (c) To include any material information with respect to the
            plan of distribution not previously disclosed in the Registration
            Statement or any material change to such information in the
            Registration Statement.


                                      II-2


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

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

            (4) The undersigned registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            (5) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the provisions set forth in Item 15 above, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer,
or controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.


                                      II-3


                                   SIGNATURES

            Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of New York, State of New York, on this 5th day of
February, 2004.
