      Armor Division

      We manufacture aviation and other armor and we armor vehicles through our
Armor Division. During 2004, 2003 and 2002 revenues from our Armor Division were
approximately $18.0 million, $3.4 million and $2.7 million, respectively (on a

since January 1, 2002, revenues in 2004, 2003 and 2002 would have been
approximately $29.2 million, $10.9 million and $13.3 million, respectively).

      AIRCRAFT ARMORING

      We are an innovative manufacturer of lightweight personal, vehicle,
aviation, architectural and marine ballistic armoring. Our Armor Division has
years of battlefield and commercial protection experience and has provided life
saving protection under the most extreme conditions. Through our subsidiary
Armour of America, located in Los Angeles, California, we manufacturer ballistic
and fragmentation armor kits for rotary and fixed wing aircraft, marine armor,
personnel armor, military vehicles, architectural applications, including both
the LEGUARD Tactical Leg Armor and the Armourfloat Ballistic Floatation Device,
which is a unique armored floatation vest that is certified by the U.S. Coast
Guard.

      We produce two kinds of armor, soft armor and hard armor, to support
customer armor requirements. Soft armor, which is capable of protecting against
all handguns and 9mm sub guns, is used in our ballistic and fragmentation vest,
military vehicle, marine, architectural and special application armor lines.
Hard armor, which is capable of protecting against rifle fire up to 50cal/12.7mm
API, is used in our ballistic chest plate, aircraft, military vehicle, marine
and architectural armor lines. Within these two basic kinds of armor, we offer
the product lines listed below.

      Fixed and Rotary Wing Aircraft Armor Systems

      We design and manufacture ballistic armor systems for a wide variety of
fixed and rotary wing aircraft. These systems are in the form of kits, with


                                       5


individual contoured panels which cover the entire aircraft's floor, walls,
seats, bulkheads, walls, oxygen containers, avionics and doors. All of our
ballistic armor kits include a complete installation hardware kit containing all
items required for installation. The supplied hardware is designed for each
individual application in accordance with the installation hardware
certification, which has been provided by Lockheed-Martin. Additionally, the
fixed and rotary wing aircraft kits have been certified, by an independent test
facility that is approved by the FAA, to meet flammability requirements of
FAA/FAR 25.853, 12 Second Vertical Test and MIL-STD-810 Environmental Testing.

      Military Vehicles Armor Kits

      For the military vehicle market, we provide ballistic armor kits to
protect against fragmentation and rifle fire, up to 50cal API for Humvees, 2
1/2- and 5-ton trucks, HEMTT wreckers and various construction vehicles. These
kits offer varying levels of protection for doors, floors, fuel tanks, air
bottles, cargo beds, troop seat backs, critical components and glass. To date,
we have protected vehicles deployed in Iraq, Afghanistan, and Kuwait. All of the
provided kits are designed for easy field level installation and include
required hardware and instructions.

      Marine Armor Kits

      For the marine market, we manufacture armor kits for the gun mounts on
naval ships and riverine patrol boats. During Operation Desert Storm, we
designed and manufactured .50 cal AP ballistic panels and deck mount brackets
for the U.S. Navy. Since then, we have designed and manufactured armor to fit
both the .50 cal and 25mm gun mounts on frigates, destroyers, cruisers and
aircraft carriers. The result of this effort is that we have delivered armor
systems to individual ships in the class and currently are pursuing armoring
additional classes of ships throughout the Navy Command.

      Ballistic Vests and Plates and Body Armor

      We manufacture a complete line of personal body armor, including
concealable, external and special application armor. The concealable armor vest
offers complete front, side and back protection using soft, lightweight, high
strength proprietary woven ballistic fabrics.

      Our external vest line includes assault, tactical, riot, stab and T-panel
designs. Each of these designs can be modified to meet the individual wearer of
customer's requirements. Special application vests include the Armourfloat,
which to our knowledge is currently the only ballistic/floatation vest approved
by the U.S. Coast Guard; the Zip Out armor jacket, which offers covert
protection in both a lightweight jacket or vest design; and our helicopter vest,
which incorporates a unique protection/comfort design.

      We offer a complete line of personal body armor including concealable
ballistic vests, military vests and external tactical vests as well as a line of
products specially designed for U.S. Navy Seal Teams and various law enforcement
agencies in the United States and overseas. Our hard ballistic armor, designed
to stop military rifle fire up to and including .50 caliber and European 12.7 mm
Armor Piercing Incendiary (API) rounds, is used primarily on fixed and rotary
wing aircraft, military ships and military vehicles, as well as in architectural
applications.

      We have designed and manufactured special operations personal armor
including ballistic hand held shields and the LEGUARD(R) Tactical Leg Armor,
which offers complete front protection for the lower thigh, knee, shin and
instep. 

      Other Armor for Specialty Applications

      In addition to aircraft, marine, vehicle and vest armor, we also
manufacture ballistic and fragmentation blankets and curtains for numerous
specialty applications. These applications include operator protection around
test equipment; rupture protection of pressure vessels, mechanical failure of
production machinery and high pressure piping. Additionally, we have supplied
armor for office use in protection of occupants from blast and glass fragments
of windows and isolation of security rooms from surrounding environments.

      VEHICLE ARMORING

      Through our majority-owned MDT Protective Industries Ltd. and MDT Armor
Corporation subsidiaries, we specialize in using state-of-the-art lightweight


                                       6


ceramic materials, special ballistic glass and advanced engineering processes to
fully armor vans and cars. MDT is a leading supplier to the Israeli military,
Israeli special forces and special services. MDT's products are proven in
intensive battlefield situations and under actual terrorist attack conditions,
and are designed to meet the demanding requirements of governmental and private
sector customers worldwide.

      Battery and Power Systems Division

      We manufacture and sell lithium and Zinc-Air batteries for defense and
security products and other military applications and we pioneer advancements in
Zinc-Air technology for electric vehicles through our Battery and Power Systems
Division. During 2004, 2003 and 2002 revenues from our Battery and Power Systems
Division were approximately $10.5 million, $5.9 million and $1.7 million,
respectively (on a pro forma basis, assuming we had owned all components of our
Battery and Power Systems Division since January 1, 2002, revenues in 2004, 2003
and 2002 would have been approximately $10.5 million, $10.8 million and $6.5
million, respectively).

      LITHIUM BATTERIES AND CHARGING SYSTEMS FOR THE MILITARY

      We sell lithium batteries and charging systems to the military through our
subsidiary Epsilor Electronic Industries, Ltd., an Israeli corporation
established in 1985 that we purchased early in 2004.

      We specialize in the design and manufacture of primary and rechargeable
batteries, related electronic circuits and associated chargers for military
applications. We have experience in working with government agencies, the
military and large corporations. Our technical team has significant expertise in
the fields of electrochemistry, electronics, software and battery design,
production, packaging and testing.

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

      We base our strategy in the field of Zinc-Air military batteries on the
development and commercialization of our Zinc-Air fuel cell technology, as
applied in the batteries we produce for the U.S. Army's Communications and
Electronics Command (CECOM) through our subsidiary Electric Fuel Battery
Corporation. We will continue to seek new applications for our technology in
defense projects, wherever synergistic technology and business benefits may
exist. We intend to continue to develop our battery products for defense
agencies, and plan to sell our products either directly to such agencies or
through prime contractors. We will also look to extend our reach to military
markets outside the United States.

      Since 1998 we have received and performed a series of contracts from CECOM
to develop and evaluate advanced primary Zinc-Air fuel cell packs. Pursuant to
these contracts, we developed and began selling in 2002 a 12/24 volt, 800
watt-hour battery pack for battlefield power, which is based on our Zinc-Air
fuel cell technology, weighs only six pounds and has approximately twice the
energy capacity per pound of the U.S. Army's standard lithium-sulfur dioxide
battery packs - the BA-8180/U battery.

      In the second half of 2002, our five-year program with CECOM to develop a
Zinc-Air battery for battlefield power culminated in the assignment of a
National Stock Number and a $2.5 million delivery order for the newly designated
BA-8180/U battery. Subsequent to this initial $2.5 million delivery order, we
received additional follow-on orders from the Army.

      Our batteries have been used in both Afghanistan (Operation Enduring
Freedom) and in Iraq (Operation Iraqi Freedom). In June of 2004, our BA-8180
Zinc-Air battery was recognized by the U.S Army Research, Development and
Engineering Command as one of the top ten inventions of 2003.

      Our Zinc-Air fuel cells, batteries and chargers for the military are
manufactured through our Electric Fuel Battery Corporation subsidiary. In 2003,
our EFB facilities were granted ISO 9001 "Top Quality Standard" certification.

      ELECTRIC VEHICLE

      We believe that electric buses represent a particularly important market
for electric vehicles in the United States. An all-electric, full-size bus


                                       7


powered by the Electric Fuel system can provide to transit authorities a full
day's operating range for both heavy duty city and suburban routes in all
weather conditions. We conduct our electric vehicle activities through our
subsidiary Electric Fuel Ltd.

      LIFEJACKET LIGHTS

      In 1996, we began to produce and market lifejacket lights built with our
patented magnesium-cuprous chloride batteries, which are activated by immersion
in water (water-activated batteries), for the aviation and marine safety and
emergency markets. Additionally, in 2004 we added two new models to our line of
lifejacket light, based on lithium batteries. At present we have a product line
consisting of seven lifejacket light models, five for use with marine life
jackets and two for use with aviation life vests, all of which work in both
freshwater and seawater. Each of our lifejacket lights is certified for use by
relevant governmental agencies under various U.S. and international regulations.
We manufacture, assemble and package all our lifejacket lights through EFL in
our factory in Beit Shemesh, Israel.

      Facilities

      Our principal executive offices have recently been re-located to EFB's
premises at 354 Industry Drive, Auburn, Alabama 36830, and our telephone number

                                  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 or exercisable 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 incurred significant net losses since our inception.
Additionally, as of March 31, 2005, we had an accumulated deficit of
approximately $121.4 million. There can be no assurance that we will ever be
able to achieve or 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 bank and certificated indebtedness (short and long term) aggregated
approximately $19.1 million as of March 31, 2005 (not including trade payables,
other account payables and accrued severance pay). 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.


                                       9


      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 future
cash flows or assets would be sufficient to repay in full such indebtedness.

      Failure to comply with the earnout provisions of our acquisition
agreements could have material adverse consequences for us.

      A failure to comply with the obligations contained in our acquisition
agreements to make the earnout payments required under such agreements could
result in actions for damages, a possible right of rescission on the part of the
sellers, and the acceleration of debt under instruments evidencing indebtedness
that may contain cross-acceleration or cross-default provisions. If we are
unable to raise capital in order to pay the earnout provisions of our
acquisition agreements, there can be no assurance that our future cash flows or
assets would be sufficient to pay such obligations.

      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 market our products and develop and market
new products. To the extent that we are unable to fully fund our operations
through profitable sales of our products and services, we may 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, on acceptable terms, or at all. 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.

      Any inability to continue to make use from time to time of our
subsidiaries' current working capital lines of credit could have an adverse
effect on our ability to do business.

      From time to time our working capital needs are partially dependent on our
subsidiaries' lines of credit. In the event that we are unable to continue to
make use of our subsidiaries' lines of credit for working capital on
economically feasible terms, our business, operating results and financial
condition could be adversely affected.

      We may not be successful in operating new businesses.

      Prior to the acquisitions of IES and MDT in 2002 and the acquisitions of
FAAC and Epsilor in January 2004 and AoA in August 2004, 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 our acquisitions, a substantial component
of our business is the marketing and sale of hi-tech multimedia and interactive
training solutions and sophisticated lightweight materials and advanced
engineering processes used to armor vehicles. These are relatively new
businesses for us and our management group has limited experience operating
these types of businesses. Although we have retained our acquired companies'
management personnel, we cannot assure that such personnel will continue to work
for us or that we will be successful in managing these new businesses. If we are
unable to successfully operate these new businesses, our business, financial
condition and results of operations could be materially impaired.


                                       10


      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 officers,
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 acquisitions.

      In light of our acquisitions of IES, MDT, FAAC, Epsilor and AoA, 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 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.

      As a result of our acquisitions, we are currently experiencing a period of
significant 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.

      A significant portion of our business is dependent on government contracts
and reduction or reallocation of defense or law enforcement spending could
reduce our revenues.

      Many of the customers of IES, FAAC and AoA 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 EFB's sales to date of 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 or law
enforcement spending in the U.S. or other countries could reduce our revenues
and have a material adverse effect on our future results of operations and
financial condition. MDT has already experienced a slowdown in orders from the


                                       11


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
has only recently opened a factory.

      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 reduce our revenues and have a material adverse effect on our future
results of operations and financial condition.

      Our U.S. government contracts may be terminated at any time and may
contain other unfavorable provisions.

      The U.S. government typically can terminate or modify any of its contracts
with us either for its convenience or if we default by failing to perform under
the terms of the applicable contract. A termination arising out of our default
could expose us to liability and have a material adverse effect on our ability
to re-compete for future contracts and orders. Our U.S. government contracts
contain provisions that allow the U.S. government to unilaterally suspend us
from receiving new contracts pending resolution of alleged violations of
procurement laws or regulations, reduce the value of existing contracts, issue
modifications to a contract and control and potentially prohibit the export of
our products, services and associated materials.

      A negative audit by the U.S. government could adversely affect our
business, and we might not be reimbursed by the government for costs that we
have expended on our contracts.

      Government agencies routinely audit government contracts. These agencies
review a contractor's performance on its contract, pricing practices, cost
structure and compliance with applicable laws, regulations and standards. If we
are audited, we will not be reimbursed for any costs found to be improperly
allocated to a specific contract, while we would be required to refund any
improper costs for which we had already been reimbursed. Therefore, an audit
could result in a substantial adjustment to our revenues. If a government audit
uncovers improper or illegal activities, we may be subject to civil and criminal
penalties and administrative sanctions, including termination of contracts,
forfeitures of profits, suspension of payments, fines and suspension or
debarment from doing business with United States government agencies. We could
suffer serious reputational harm if allegations of impropriety were made against
us. A governmental determination of impropriety or illegality, or an allegation
of impropriety, could have a material adverse effect on our business, financial
condition or results of operations.

      We may be liable for penalties under a variety of procurement rules and
regulations, and changes in government regulations could adversely impact our
revenues, operating expenses and profitability.

      Our defense and commercial businesses must comply with and are affected by
various government regulations that impact our operating costs, profit margins
and our internal organization and operation of our businesses. Among the most
significant regulations are the following:

      o     the U.S. Federal Acquisition Regulations, which regulate the
            formation, administration and performance of government contracts;

      o     the U.S. Truth in Negotiations Act, which requires certification and
            disclosure of all cost and pricing data in connection with contract
            negotiations; and

      o     the U.S. Cost Accounting Standards, which impose accounting
            requirements that govern our right to reimbursement under certain
            cost-based government contracts.


                                       12


      These regulations affect how we and our customers do business and, in some
instances, impose added costs on our businesses. Any changes in applicable laws
could adversely affect the financial performance of the business affected by the
changed regulations. With respect to U.S. government contracts, any failure to
comply with applicable laws could result in contract termination, price or fee
reductions or suspension or debarment from contracting with the U.S. government.

      Our operating margins may decline under our fixed-price contracts if we
fail to estimate accurately the time and resources necessary to satisfy our
obligations.

      Some of our contracts are fixed-price contracts under which we bear the
risk of any cost overruns. Our profits are adversely affected if our costs under
these contracts exceed the assumptions that we used in bidding for the contract.
Often, we are required to fix the price for a contract before we finalize the
project specifications, which increases the risk that we will mis-price these
contracts. The complexity of many of our engagements makes accurately estimating
our time and resources more difficult.

      If we are unable to retain our contracts with the U.S. government and
subcontracts under U.S. government prime contracts in the competitive rebidding
process, our revenues may suffer.

      Upon expiration of a U.S. government contract or subcontract under a U.S.
government prime contract, if the government customer requires further services
of the type provided in the contract, there is frequently a competitive
rebidding process. We cannot guarantee that we, or if we are a subcontractor
that the prime contractor, will win any particular bid, or that we will be able
to replace business lost upon expiration or completion of a contract. Further,
all U.S. government contracts are subject to protest by competitors. The
termination of several of our significant contracts or nonrenewal of several of
our significant contracts, could result in significant revenue shortfalls.

      The loss of, or a significant reduction in, U.S. military business would
have a material adverse effect on us.

      U.S. military contracts account for a significant portion of our business.
The U.S. military funds these contracts in annual increments. These contracts
require subsequent authorization and appropriation that may not occur or that
may be greater than or less than the total amount of the contract. Changes in
the U.S. military's budget, spending allocations and the timing of such spending
could adversely affect our ability to receive future contracts. None of our
contracts with the U.S. military has a minimum purchase commitment, and the U.S.
military generally has the right to cancel its contracts unilaterally without
prior notice. We manufacture for the U.S. aircraft and land vehicle armor
systems, protective equipment for military personnel and other technologies used
to protect soldiers in a variety of life-threatening or catastrophic situations,
and batteries for communications devices. The loss of, or a significant
reduction in, U.S. military business for our aircraft and land vehicle armor
systems, other protective equipment, or batteries could have a material adverse
effect on our business, financial condition, results of operations and
liquidity.

      A reduction of U.S. force levels in Iraq may affect our results of
operations.

      Since the invasion of Iraq by the U.S. and other forces in March 2003, we
have received steadily increasing orders from the U.S. military for armoring of
vehicles and military batteries. These orders are the result, in substantial
part, from the particular combat situations encountered by the U.S. military in
Iraq. We cannot be certain, therefore, to what degree the U.S. military would
continue placing orders for our products if the U.S. military were to reduce its
force levels or withdraw completely from Iraq. A significant reduction in orders
from the U.S. military could have a material adverse effect on our business,
financial condition, results of operations and liquidity.

      There are limited sources for some of our raw materials, which may
significantly curtail our manufacturing operations.

      The raw materials that we use in manufacturing our armor products include
Kevlar(R), a patented product of E.I. du Pont de Nemours Co., Inc. We purchase
Kevlar in the form of woven cloth from various independent weaving companies. In
the event Du Pont and/or these independent weaving companies were to cease, for
any reason, to produce or sell Kevlar to us, we might be unable to replace it
with a material of like weight and strength, or at all. Thus, if our supply of


                                       13


Kevlar were materially reduced or cut off or if there were a material increase
in the price of Kevlar, our manufacturing operations could be adversely affected
and our costs increased, and our business, financial condition and results of
operations could be materially adversely affected.

      Some of the components of our products pose potential safety risks which
could create potential liability exposure for us.

      Some of the components of our products contain elements that are known to
pose potential safety risks. In addition to these risks, 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. In the event that our products,
including the products manufactured by MDT and AoA, fail to perform as
specified, users of these products may assert claims for substantial amounts.
These claims could have a materially adverse effect on our financial condition
and results of operations. There is no assurance that the amount of the general
product liability insurance that we maintain 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.

      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.

      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.

      Many of our competitors have financial, technical, marketing, sales,
manufacturing, distribution and other resources significantly greater than ours.
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.

      Our business is dependent on 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.

      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


                                       14


successful in the litigation. 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 need to acquire a license under such patents to develop and
market our products.

      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. 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, and entities with which we maintain strategic
relationships. 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 the presidents of our IES, FAAC and AoA
subsidiaries and the general managers of our MDT and Epsilor subsidiaries, 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 2007. 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 2004, 2003 and 2002, without taking
account of revenues derived from discontinued operations, 19%, 42% and 56%,
respectively, of our revenues, 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:


                                       15


      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;

      o     The issuance of our securities, including warrants, in connection
            with financings and acquisitions; 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
traded below $1.00 in the 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 Securities
Exchange Act of 1934, as amended, 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.

      Our management has determined that we have material weaknesses in our
internal controls. If we fail to achieve and maintain effective internal
controls in accordance with Section 404 of the Sarbanes-Oxley Act, we may not be
able to accurately report our financial results.

      We have, with our auditors' concurrence, identified significant
deficiencies that constitute material weaknesses under standards established by
the Public Company Accounting Oversight Board (PCAOB). A material weakness is a
condition in which the design or operation of one or more of the internal


                                       16


control components does not reduce to a relatively low level the risk that
misstatements caused by error or fraud in amounts that would be material in
relation to the financial statements being audited may occur and not be detected
within a timely period by employees in the normal course of performing their
assigned functions. Our auditors have reported to us that at December 31, 2004,
we had material weaknesses for inadequate controls related to the financial
statement close process, convertible debentures and share capital processes as
it applies to non-routine and highly complex financial transactions. The
material weaknesses arise from insufficient staff with technical accounting
expertise to independently apply our accounting policies, as they relate to
non-routine and highly complex transactions, in accordance with U.S. generally
accepted accounting principles.

      As a public company, we will have significant requirements for enhanced
financial reporting and internal controls. The process of designing and
implementing effective internal controls is a continuous effort that requires us
to anticipate and react to changes in our business and the economic and
regulatory environments and to expend significant resources to maintain a system
of internal controls that is adequate to satisfy our reporting obligations as a
public company. We cannot assure you that the measures we have taken or will
take to remediate any material weaknesses or that we will implement and maintain
adequate controls over our financial processes and reporting in the future as we
continue our rapid growth. If we are unable to establish appropriate internal
financial reporting controls and procedures, it could cause us to fail to meet
our reporting obligations, result in material misstatements in our financial
statements, harm our operating results, cause investors to lose confidence in
our reported financial information and have a negative effect on the market
price for shares of our common stock.

      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 March 31, 2005, we had 80,103,668 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.

      Exercise of our warrants, options and convertible debt could adversely
affect our stock price and will be dilutive.

      As of March 31, 2005, there were outstanding warrants to purchase a total
of 16,961,463 shares of our common stock at a weighted average exercise price of
$1.55 per share, options to purchase a total of 9,284,047 shares of our common
stock at a weighted average exercise price of $1.33 per share, of which
7,168,676 were vested, at a weighted average exercise price of $1.34 per share,
and outstanding debentures convertible into a total of 3,156,298 shares of our
common stock at a weighted average conversion price of $1.44 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.

      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


                                       17


      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 three of our subsidiaries, EFL, MDT and
Epsilor, are located in Israel (in Beit Shemesh, Lod and Dimona, respectively,
all of which are within Israel's pre-1967 borders). 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.

      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 22%
of our assets are located outside the United States. In addition, two of our
directors and most 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. 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.

      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 portion of our costs,


                                       18


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. In 2004, the inflation adjusted
NIS appreciated against the dollar, which raised the dollar cost of our Israeli
operations.

      Some of our agreements are governed by Israeli law.

      Israeli law governs some of our agreements, such as our lease agreements
on our subsidiaries' premises in Israel, and the agreements pursuant to which we
purchased IES, MDT and Epsilor. 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.

                INFORMATION REGARDING FORWARD-LOOKING STATEMENTS

      When used in this prospectus, the words "expects," "anticipates,"
"estimates" and similar expressions identify forward-looking statements. These
statements are "forward-looking" statements within the meaning of Section 27A of
the Securities Act and Section 21E of the Exchange Act. These statements, which
include statements under the caption "Risk Factors" and elsewhere in this
prospectus, refer to the stage of development of our products, the uncertainty
of the market for disposable cell phone batteries, significant future capital
requirements and our plans to implement our growth strategy, continue our
research and development, expand our manufacturing capacity, develop strategic
relationships for marketing and other purposes and carefully manage our growth.
The forward-looking statements also include our expectations concerning factors
affecting the markets for our products.

      These forward-looking statements are subject to risks and uncertainties
that could cause actual results to differ materially from the results that we
anticipate. These risks and uncertainties include, but are not limited to, those
risks discussed in this prospectus and in the documents incorporated by
reference in this prospectus.

      All such forward-looking statements are current only as of the date on
which such statements were made. We assume no obligation to update these
forward-looking statements or to update the reasons actual results could differ
materially from the results anticipated in the forward-looking statements.

      You should rely only on the information in this prospectus and the
additional information described under the heading "Where You Can Find
Additional Information." We have not authorized any other person to provide you
with different information. If anyone provides you with different or
inconsistent information, you should not rely upon it. You should assume that
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 20. The shares
offered for resale by this prospectus consist of 8,717,265 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. The shares covered hereby are
issuable upon the exercise of warrants. If these warrants are fully exercised
for cash, we will receive gross proceeds of $12,029,825. Such proceeds would be
added to working capital and used for general corporate purposes.


                                       19


                              SELLING STOCKHOLDERS

      Shares Issuable in Connection with Outstanding Warrants Held by Investors

      We issued warrants to certain investors in July 2004 ("Warrants") to
purchase 8,717,265 shares of our common stock at a purchase price of $1.38 per
share. The Warrants are exercisable at any time until July 14, 2009.

      The terms of the Warrants whose underlying shares of common stock are
included for resale under this prospectus prohibit exercise of the Warrants 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
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.

      We are now registering the shares underlying all the Warrants. We are
bearing the expenses of this registration.

      The above 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.

      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 December 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.

    outstanding convertible securities. Highbridge Capital Management, LLC
    ("Highbridge") is the trading manager of Smithfield Fiduciary LLC
    ("Smithfield") and consequently has voting control and investment discretion
    over the securities held by Smithfield. Messrs. Glenn Dubin and Henry Swieca
    control Highbridge. Each of Highbridge and Messrs. Dubin and Swieca
    disclaims beneficial ownership of the securities held by Smithfield.
(5) Includes 392,593 previously-registered shares issuable upon exercise of
    outstanding convertible securities. Omicron Capital, L.P., a Delaware
    limited partnership ("Omicron Capital"), serves as investment manager to
    Omicron Master Trust, a trust formed under the laws of Bermuda ("Omicron"),
    Omicron Capital, Inc., a Delaware corporation ("OCI"), serves as general
    partner of Omicron Capital, and Winchester Global Trust Company Limited
    ("Winchester") serves as the trustee of Omicron. By reason of such
    relationships, Omicron Capital and OCI may be deemed to share dispositive
    power over the securities owned by Omicron, and Winchester may be deemed to
    share voting and dispositive power over the securities owned by Omicron.
    Omicron Capital, OCI and Winchester disclaim beneficial ownership of such
    securities. Omicron Capital has delegated authority from the board of
    directors of Winchester regarding the portfolio management decisions with
    respect to the securities owned by Omicron and, as of April 21, 2003, Mr.
    Olivier H. Morali and Mr. Bruce T. Bernstein, officers of OCI, have
    delegated authority from the board of directors of OCI regarding the
    portfolio management decisions of Omicron Capital with respect to the
    securities owned by Omicron. By reason of such delegated authority, Messrs.
    Morali and Bernstein may be deemed to share dispositive power over the
    securities owned by Omicron. Messrs. Morali and Bernstein disclaim
    beneficial ownership of such securities and neither of such persons has any
    legal right to maintain such delegated authority. No other person has sole
    or shared voting or dispositive power with respect to the securities being
    offered by Omicron, as those terms are used for purposes under Regulation
    13D-G of the Securities Exchange Act of 1934, as amended. Omicron and
    Winchester are not "affiliates" of one another, as that term is used for
    purposes of the Securities Exchange Act of 1934, as amended, or of any other
    person named in this prospectus as a selling stockholder. No person or
    "group" (as that term is used in Section 13(d) of the Securities Exchange
    Act of 1934, as amended, or the SEC's Regulation 13D-G) controls Omicron and
    Winchester.
(6) Includes 776,390 previously-registered shares issuable upon exercise of
    outstanding convertible securities. Ramius Capital Group, LLC is the
    investment adviser of Portside Growth and Opportunity Fund and consequently
    has voting control and investment discretion over securities held by
    Portside. Ramius Capital disclaims beneficial ownership of the securities
    held by Portside. Peter A. Cohen, Morgan B. Stark, Thomas W. Strauss and
    Jeffrey M. Solomon are the sole managing members of C4S & Co., LLC, the sole

                              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:


                                       21


      >>    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;

      >>    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


                                       22


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.

      We are required to pay all fees and expenses incident to the registration
of the shares and up to $10,000 of the fees and disbursements of 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 250,000,000 shares of common
stock par value $0.01 per share, and 1,000,000 shares of preferred stock, par
value $0.01 per share. As of March 31, 2005, 80,103,668 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.


                                       23


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.

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.

      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:


                                       24


      >>    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


                                      II-1


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.

      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,


                                      II-2


            (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.

      (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.
