ABOUT US We are a defense and security products and services company, engaged in three business areas: interactive simulation for military, law enforcement and commercial markets; batteries and charging systems for the military; and high-level armoring for military, paramilitary and commercial vehicles. Until September 17, 2003, we were known as Electric Fuel Corporation. We operate primarily as a holding company, through our various subsidiaries, which are organized into three divisions. Our divisions and subsidiaries are as follows: o 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 security consulting and other services (our SIMULATION, TRAINING AND CONSULTING DIVISION), consisting of: o IES Interactive Training, Inc., located in Littleton, Colorado, which provides specialized "use of force" training for police, security personnel and the military ("IES"); o FAAC Incorporated, located in Ann Arbor, Michigan, which provides simulators, systems engineering and software products to the United States military, government and private industry ("FAAC"); and o Arocon Security Corporation, located in New York, New York, which provides security consulting and other services, focusing on protecting life, assets and operations with minimum hindrance to personal freedom and daily activities ("Arocon"). o We manufacture and sell Zinc-Air and lithium batteries for defense and security products and other military applications and we pioneer advancements in Zinc-Air technology for electric vehicles (our BATTERY AND POWER SYSTEMS DIVISION), consisting of: o Electric Fuel Battery Corporation, located in Auburn, Alabama, which manufactures and sells Zinc-Air fuel cells, batteries and chargers for the military, focusing on applications that demand high energy and light weight ("EFB"); o Epsilor Electronic Industries, Ltd., located in Dimona, Israel (in Israel's Negev desert area), which develops and sells rechargeable and primary lithium batteries and smart chargers to the military and to private industry in the Middle East, Europe and Asia ("Epsilor"); and o Electric Fuel (E.F.L.) Ltd., located in Beit Shemesh, Israel, which produces water-activated lifejacket lights for commercial aviation and marine applica- 3 tions, and which conducts our Electric Vehicle effort, focusing 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 our Zinc-Air energy system for electric vehicles ("EFL"). o We utilize sophisticated lightweight materials and advanced engineering processes to armor vehicles (our ARMORED VEHICLE DIVISION), consisting of: o MDT Protective Industries, Ltd., located in Lod, Israel, which specialize in using state-of-the-art lightweight ceramic materials, special ballistic glass and advanced engineering processes to fully armor vans and cars, and is a leading supplier to the Israeli military, Israeli special forces and special services ("MDT"), of which we own 75.5%; and o MDT Armor Corporation, located in Auburn, Alabama, which conducts MDT's United States activities ("MDT Armor"), of which we own 88%. We acquired FAAC and Epsilor in early 2004. Prior to the acquisition of FAAC and Epsilor, we were organized into two divisions: Defense and Security Products (consisting of IES, MDT, MDT Armor and Arocon), and Electric Fuel Batteries (consisting of EFL and EFB). We have reported our results of operations for 2003 and 2002 in accordance with these earlier divisions, and our financial results for 2003 and 2002 do not include the activities of FAAC or Epsilor. SIMULATION, TRAINING AND CONSULTING DIVISION USE-OF-FORCE TRAINING Through our wholly-owned subsidiary, IES Interactive Training, Inc., we provide specialized "use of force" training for police, 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 and law enforcement agencies, including (in the United States) the FBI, the Secret Service, the Bureau of Alcohol, Tobacco and Firearms, the Customs Service, the Federal Protective Service, the Border Patrol, the Bureau of Engraving and Printing, the Coast Guard, the Federal Law Enforcement Training Centers, the Department of Health and Human Services, the California Department of Corrections, NASA, police departments in Texas (Houston), Michigan (Detroit), D.C., California (Fresno and the California Highway Patrol), Massachusetts (Brookline), Virginia (Newport News and the State Police Academy), Arizona (Maricopa County), universities and nuclear power plants, as well as 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 500 other training departments worldwide. Our interactive training systems vary 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. 4 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 179 simulators that have successfully trained over 80,000 drivers. FAAC's customer base includes all branches of the Department of Defense, state and local governments, and commercial entities. We believe that 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 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, mission operator station and real-time, database driven electronic combat environment for the special operational forces aircrew training system. The special operational forces aircrew training system provides a full range of aircrew training, including initial qualification, mission qualification, continuation, and upgrade training, as well as combat mission rehearsal. SECURITY CONSULTING Arocon Security Corporation focuses on protecting life, assets and operations with minimum hindrance to personal freedom and daily activities. Arocon Security, which provides 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 security products and technology in the United States. BATTERY AND POWER SYSTEMS DIVISION ZINC-AIR FUEL CELLS, BATTERIES AND CHARGERS FOR THE MILITARY We have been engaged in research and development in the field of Zinc-Air electrochemistry and battery design for over ten years, as a result of which we have developed our current Zinc-Air technology and its applications. We have successfully applied our technology to our high-energy battery packs for military and security applications. We have also applied our technology to the development of a refuelable Zinc-Air fuel cell for powering zero-emission electric vehicles. Through these efforts, we have sought to position ourselves as a world leader in the application of Zinc-Air technology to innovative primary and refuelable power sources. Our primary existing battery product for the military and defense sectors is 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, which offer extended-use portable power using our commercial Zinc-Air cell technology. Our BA-8180/U battery has received a National Stock Number (a Department of Defense catalog number assigned to products authorized for use by the U.S. military), making our batteries available for purchase by all units of the U.S. Armed Forces. 5 We believe that our Zinc-Air batteries provide 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. 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 finding a strategic partner that can lead the way 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. LIFEJACKET LIGHTS We produce water-activated lifejacket lights for commercial aviation and marine applications based on our patented water-activated magnesium-cuprous chloride battery technology. We intend to continue to work with original equipment manufacturers (OEMs), distributors and end-user companies to expand our market share in the aviation and marine segments. We presently sell five products in the safety products group, three for use with marine life jackets and two for use with aviation life vests. All five products are certified under applicable international marine and aviation safety regulations. ARMORED VEHICLE DIVISION Through our majority-owned MDT Protective Industries Ltd. and MDT Armor Corporation subsidiaries, we specialize in using state-of-the-art lightweight 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.

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 incurred significant operating losses since our inception. Additionally, as of December 31, 2003, we had an accumulated deficit of approximately $110.0 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 $8.7 million as of December 31, 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. 7 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 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 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 acquisitions of IES and MDT in 2002 and the acquisitions of FAAC and Epsilor early in 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 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 this new business. If we are unable to successfully operate these new businesses, our business, financial condition and results of operations could be materially impaired. 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 8 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, MDT, FAAC and Epsilor, 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. A SIGNIFICANT PORTION OF OUR BUSINESS IS DEPENDENT ON GOVERNMENT CONTRACTS. Many of the customers of IES and FAAC 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 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 has only recently opened 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. 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 9 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. 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. In 2003, approximately 36% of our revenues were derived from fixed-price contracts for both defense and non-defense related government contracts. 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. 10 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. WE CANNOT ASSURE YOU OF MARKET ACCEPTANCE OF OUR 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 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. We cannot assure you that we will be able to successfully develop, engineer or commercialize our Zinc-Air energy system. 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. SOME OF THE COMPONENTS OF OUR ELECTRIC VEHICLE TECHNOLOGY AND OUR PRODUCTS POSE POTENTIAL SAFETY RISKS WHICH COULD CREATE POTENTIAL LIABILITY EXPOSURE FOR US. Some of the components of our electric vehicle 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 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. In the event that our products, including the products manufactured by MDT, 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. 11 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. 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 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. 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, 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. 12 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 and FAAC 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 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 2003, 2002 and 2001, without taking account of revenues derived from discontinued operations, 42%, 56% and 49%, 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: 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 13 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. 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 April 16, 2004, we had 63,656,843 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, providing 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 3,482,534 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 April 16, 2004, there were outstanding warrants to purchase a total of 18,720,040 shares of our common stock at a weighted average exercise price of $1.84 per share, options to purchase a total of 7,576,041 shares of our common stock at a weighted average exercise price of $1.52 per share, of which 5,733,441 were vested, at a weighted average exercise price of $1.72 per share, and outstanding debentures convertible into a total of 4,898,801 shares of our common stock at a weighted average conversion price of $1.40 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. 14 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 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. Some 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 15 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. 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 35% 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. 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, 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 2003, 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.

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 include the following: o 508,286 shares of common stock outstanding, of which 175,000 shares are owned by Yehuda Harats, our former CEO, and 333,286 are owned by Capital Ventures International; o 4,137,932 shares of common stock that may be acquired upon the conversion of currently outstanding debentures; and o 14,849,468 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 $27,997,346. Such proceeds would be added to working capital and used for general corporate purposes. SELLING STOCKHOLDERS SHARES OWNED BY OUR FORMER CEO Pursuant to the terms of a registration rights agreement with Yehuda Harats, our former CEO, we are registering a total of 175,000 shares owned by him. 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. 17 Under the terms of the Purchase Agreement, we have granted the Investors 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, and in any stock that we acquire in future Acquisitions (as defined in the Purchase Agreement), 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 with these transactions an aggregate number of shares equal to or in excess of 20% or outstanding shares of common stock. Pursuant to our obligations under the Purchase Agreement, we will solicit the approval of our shareholders regarding the issuance of the Debentures and the Warrants, as may be required under Nasdaq Marketplace Rules, at our next annual meeting of stockholders (the "Meeting"), to be called and held no later than June 19, 2004. In this connection, and as required under the terms of the Purchase Agreement, certain of our shareholders have agreed to vote their shares in favor of the approval of the transactions contemplated by the Purchase Agreement at the Meeting, pursuant to separate voting agreements. The debentures and warrants issued to the 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. SHARES ISSUED AND 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. 18 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"). In connection with the May 2001 offering, we granted warrants to purchase 250,000 shares of our common stock at a purchase price of $3.08 per share, subject to anti-dilution adjustment, to one of the selling stockholders, as partial consideration for its consent to, and waiver of certain provisions contained in a securities purchase agreement dated as of November 17, 2000 by and between us and the selling stockholder, related to our sale of certain of our securities in May 2001. In April 2004, as part of a negotiation on the number of shares such selling stockholder was entitled to pursuant to anti-dilution provisions contained in the warrants held by them and in exchange for immediate exercise of the 333,286 warrants (after operation of the antidilution provision), we issued a new warrant to such selling stockholder to purchase a total of 1,222,050 shares of our common stock at a purchase price of $2.10 per share. These warrants are exercisable at any time until the 180th day after the date of this prospectus. We are now registering the shares underlying all of these warrants and the 333,286 shares of common stock previously issued upon exercise of 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. 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. 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. 19 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 April 16, 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.

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 20 Nasdaq Marketplace Rules to issue in connection with these transactions an aggregate number of shares equal to or in excess of 20% or outstanding shares of common stock. (4) Includes (i) 1,448,276 shares of common stock issuable at a conversion price of $1.45 per share upon conversion of 8% secured convertible debentures ("Additional Debentures") that were issued in connection with an Amendment and Exercise Agreement dated December 10, 2003 (the "SPA Amendment") amending a securities purchase agreement dated September 30, 2003 (the "SPA"), (ii) 525,000 shares of common stock issuable at an exercise price of $1.8125 per share upon exercise of warrants that were issued in December 2003 in connection with the SPA Amendment ("Additional Warrants"), (iii) 363,300 shares of common stock issuable at an exercise price of $2.20 per share upon exercise of incentive warrants that were issued in December 2003 in connection with the SPA Amendment ("Incentive Warrants"), and (iv) 3,989,367 shares of common stock issuable at an exercise price of $1.88 per share upon exercise of a 2004 Warrant.

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: o ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; o 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; o purchases by a broker-dealer as principal and resale by the broker-dealer for its account; o an exchange distribution in accordance with the rules of the applicable exchange; o privately negotiated transactions; o short sales; o through the writing or settlement of option or other hedging transactions, whether through an options exchange or otherwise; o broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share; o a combination of any such methods of sale; and o any other method permitted pursuant to applicable law. 23 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. 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. 24 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 $0.01 per share, and 1,000,000 shares of preferred stock, par value $0.01 per share. As of April 16, 2004, 63,656,843 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. STOCK OPTIONS As of April 16, 2004, options to purchase a total of 7,576,041 shares of common stock at a weighted average exercise price of $1.52 per share were outstanding, 5,733,441 of which were vested and exercisable within 60 days of the date of this prospectus, at a weighted average exercise price of $1.72 per share. WARRANTS As of April 16, 2004, there were outstanding warrants to purchase a total of 18,720,040 shares of common stock at a weighted average exercise price of $1.84 per share. 25 DEBENTURES As of April 16, 2004, there were outstanding debentures convertible into a total of 4,898,801 shares of common stock at a weighted average conversion price of $1.40 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. 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: o 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; o subdivide or combine our common stock; or o issue shares of our capital stock in any reclassification of our common stock. 26 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.
