Prospectus Summary

This summary highlights information contained in other parts of this prospectus. Because it is a summary, it does not contain all of the information that you should consider before investing in the ordinary shares. You should read the entire prospectus carefully. The terms "we," "us" and "Tower" mean Tower Semiconductor Ltd. and its consolidated subsidiary. Unless otherwise stated, all information contained in this prospectus assumes no exercise of the over-allotment option granted to the underwriters.

   

Tower Semiconductor

We are a pure-play independent wafer foundry dedicated to the manufacture of integrated circuits, or ICs, using complementary metal oxide semiconductor, or CMOS, process technology. ICs manufactured by us are incorporated into a wide range of products in diverse markets, including consumer electronics, personal computer and office equipment, communications, automotive, professional photography and medical device products. Pure-play foundries do not offer any products of their own, but focus on producing ICs based on the design specifications of their customers.

We manufacture ICs with geometries ranging from 1.0 to 0.35 microns at our 150-mm fabrication facility, or Fab 1, and 0.18 microns at our recently constructed 200-mm fabrication facility, or Fab 2. We plan to initiate volume production in geometries of 0.13 microns at Fab 2 during 2005. At Fab 1, we have expanded capacity to approximately 16,000 wafer starts per month. We began volume production at Fab 2 during the third quarter of 2003. The production capacity at the end of December 2003 was 8,500 wafer starts per month, and we currently expect to have production capacity ranging between 13,000 and 15,000 wafer starts per month by the end of 2004. We expect the production ramp to be completed by the end of 2006, at which time Fab 2 is expected to have the capacity to produce 33,000 wafer starts per month. While we expect to continue to operate Fab 1, we expect Fab 2 to form the core of our future business.

With increased demand for new semiconductor applications, particularly in the consumer sector, the semiconductor industry is now recovering from its worst downturn in history. According to the Worldwide Semiconductor Trade Statistic Organization, worldwide sales of semiconductors increased 6.8% to $15.4 billion in October 2003, up from $14.4 billion in September 2003, representing the eighth consecutive monthly increase. The consumer sector, which currently represents 17% of semiconductor demand, is expanding worldwide with new applications and multi-functional devices, including those that incorporate technologies in which we specialize: CMOS image sensors, embedded flash and mixed-signal ICs.

Market Opportunity

We believe that the key factors that drive growth in our business include:

the increasing demand for complex ICs, which creates an expanding market for outsourced manufacturing;
the growing popularity of applications and products that use technologies in which we focus on, including CMOS image sensors, embedded flash and mixed-signal ICs;
the incentive of SanDisk, Alliance Semiconductor, Macronix and QuickLogic (which we refer to as our "wafer partners") to utilize their right to purchase up to approximately 50% of the capacity of our Fab 2 facility;
the limited number of independent foundries due to the prohibitively high cost of building new fabrication facilities, or fabs, which requires high capacity utilization to ensure that fixed costs are absorbed; and
the current, eight-consecutive-month upswing in semiconductor demand, which we believe, based on market data information made publicly available by leading Asian foundries, will result in a capacity shortage at these foundries and create an opportunity for us to obtain new customers. Two leading Taiwanese foundries, which according to IC Insights account for over 70% of worldwide sales of ICs, recently reported that they both expect to achieve overall utilization rates exceeding 90% in the fourth quarter of 2003.

With Fab 2 having commenced commercial production in the third quarter of 2003, we believe that we are particularly well positioned to benefit from the expected upswing in the

5




semiconductor market and corresponding capacity shortage in leading Asian foundries, as we are one of a few semiconductor manufacturers that increased its investments in new capacity during the recent industry downturn.

Target Markets

We focus on the emerging opportunities surrounding CMOS image sensors, embedded flash and mixed-signal ICs where we believe we have strong expertise and proven experience. In addition to the high margins that these products generate, we are focusing on these markets because of their large size and high growth rates. According to In-Stat/MDR, a market research firm, the CMOS image sensor market is expected to grow from $184 million in 2002 to $547 million in 2007, representing a five-year compound annual growth rate of 24%. Semico Research, a market research firm, forecasts that embedded flash in microcontrollers will grow from $4.0 billion in 2002 to $17.0 billion in 2007, representing a five-year compound annual growth rate of 34%. According to Dataquest, a market research firm, the worldwide general-purpose analog and mixed-signal IC market was $9.3 billion in 2002 and is projected to grow to $17.6 billion in 2007, representing a five-year compound annual growth rate of 14%. With our advanced manufacturing technologies and service capabilities, we have established a strong position in these markets with customers which are industry leaders, including Kodak, Motorola, National Semiconductor, SanDisk and Zoran.

Strategy

The key elements of our strategy include:

Establishing Leading Market Share for Specialized, High Growth Applications. These applications include CMOS image sensors for products such as digital still cameras and camera-equipped cell phones; embedded flash in microcontrollers; and mixed-signal ICs in cell phones, PDAs and DSL modems.
Pursuing a Partnership Business Model.    We believe that the use of our customers as an equity financing source, such as in the case of our wafer partners, will strengthen our long-term relationships with these customers, as our growth objectives are closely aligned. In connection with their investment in us, we granted our existing wafer partners a right to purchase up to approximately 50% of the capacity of our Fab 2 facility, and we believe that their ownership interest provides them added incentive to utilize this capacity.
Maintaining Our Commitment to Customer Service.    We place significant emphasis on providing world-class customer service, as well as engineering support and execution of complex process and product transfers, while maintaining reduced cycle times and higher product yields. We believe that our customer service has helped us differentiate ourselves from our larger competitors, as demonstrated by Motorola naming us "Foundry of the Year" in 1999 and awarding us "Gold Supplier" status in 2000, 2001 and 2002.
Expanding Our Technological Expertise through Licensing and Joint Development Efforts with Leading Technology Companies. In addition to our independent research and development resources, we have expanded our core strengths in CMOS image sensors, embedded flash and mixed-signal technologies by combining our proprietary technologies with leading technology companies, such as Matsushita, Motorola and Toshiba.
Enhancing Our Global Sales and Marketing Efforts.    We have recently significantly increased our global sales and marketing efforts in order to establish worldwide coverage to support the ramp-up of our Fab 2 0.18-micron process technology service offering.
Maximizing Our Capacity Utilization.    We seek to maximize capacity utilization by attracting new customers and rapidly transitioning our capabilities to high-margin advanced technologies.
Becoming a Preferred Second-Source Foundry Service Provider.    As foundry utilization rates peak and available capacity decreases, we aim to attract new customers as part of their risk diversification strategy by becoming their preferred alternative or second-source provider of foundry services.

Recent Development

On December 30, 2003, we signed a memorandum of understanding with Siliconix incorporated, an 80.4% owned subsidiary of Vishay Intertechnology, Inc., for a long-term manufacturing and supply arrangement between the parties. Pursuant to the terms of the memorandum of understanding, Siliconix will place with us orders valued at approximately $200 million for the purchase of semiconductor wafers to be manufactured in our Fab 1 over a seven to ten year period, of which approximately $53 million is guaranteed and will be delivered over the three year period starting at the first anniversary of the definitive agreement. Siliconix will advance to us $20 million to be used for the purchase of additional equipment required to satisfy Siliconix's orders, which will be credited towards the purchase price of the wafers. The transaction is subject to the approval of both companies' boards of directors, our lending banks and the Israeli Investment Center and to the negotiation of definitive documentation. A definitive agreement is expected to be signed during the first quarter of 2004.

Risk Factors

You should carefully consider the following factors, together with all of the other information in this prospectus before deciding to invest in the shares.

    

Risks Affecting Our Business

If we do not complete the equipment installation, technology transfer and ramp-up of production in Fab 2, our business will be materially adversely affected.

We have completed the construction of Fab 2 but not the acquisition, installation and equipping necessary for production at our planned full capacity of 33,000 200-mm wafer starts per month, which we expect to reach by the end of 2006. We will also need to transfer 0.13 micron technology from Motorola to Fab 2 and develop new process technologies for Fab 2 in order to suit our customers' needs. The ramp-up of Fab 2 is a substantial and complex project. We are experiencing difficulties customary for projects of this type in the installation, functionality and operation of the Fab 2 equipment during its early manufacturing period. Failures or delays in obtaining and installing the necessary equipment, technology and other resources may delay the completion of the ramp-up of Fab 2 and add to its cost, which would have a material adverse effect on our business and results of operations.

If we do not have sufficient funds to complete the Fab 2 project, our business will be materially adversely affected.

We estimate that, after giving effect to this offering, we will need approximately an additional $270 million to finance the total cost of Fab 2 until we reach full capacity (including cash flow from operations and assuming net proceeds from this offering of $87.4 million). Additionally, the actual cost of Fab 2 may exceed our estimates. If we cannot successfully raise sufficient funding to complete the ramp-up to 33,000 wafer starts per month, we will be required to scale back our equipment purchases and capacity forecasts, and, as a result, we will not fully utilize the substantial investment made in constructing Fab 2, which will adversely affect our financial results.

The cyclical nature of the semiconductor industry and the resulting periodic overcapacity have adversely affected our business in the past, resulting in a history of losses; downward price pressure may seriously harm our business.

The semiconductor industry has historically been highly cyclical. Historically, companies in the semiconductor industry have expanded aggressively during periods of increased demand. This expansion has frequently resulted in overcapacity and excess inventories, leading to rapid erosion of average sale prices. We expect this pattern to repeat itself in the future. Our operating results for 1996 through 1999 were harmed by a downturn in the semiconductor market that resulted in reduced orders, underutilization of our facility and severe price erosion. Although utilization and average sale prices improved during 2000, demand slowed in the overall semiconductor market and in many of our end product markets beginning in the fourth quarter of 2000. This slowing in demand deepened in 2001 and continued in 2002. While sales increased in each of the first three quarters of 2002, and have continued to improve through the first half of 2003, we experienced a decrease in the sales of Fab 1 in the third quarter of 2003. Although the semiconductor industry appears to be recovering, we cannot be assured that this overall recovery will continue or that we will benefit from it through an increase in demand for our products, resulting in an improvement in our financial results.

We have a recent history of operating losses and expect to operate at a loss through the foreseeable future. Our facilities must operate at high utilization rate for us to be profitable.

We operated at a loss for the last five years and expect to operate at a loss for the foreseeable future. Fab 1 operated significantly below capacity from 1996 through 2003. Because fixed costs represent a substantial portion of the operating costs of semiconductor manufacturing operations, we must operate our facilities at a high utilization rate. We are currently operating Fab 1 at a capacity utilization of approximately 50%. During the third quarter of 2003, we completed the construction of Fab 2, the qualification of process technologies and the start

10




of ramp-up of production. These technologies and other Fab 2 assets have started to incur significant operating expenses as well as depreciation and amortization expenses.

We may not be able to capitalize on an increase in demand for foundry services.

We are ramping-up Fab 2 based on our expectations of customer demand. In order for demand for our wafer fabrication services to increase, the markets for the end products using these services must develop and expand. For example, the success of our imaging process technologies will depend, in part, on the growth of markets for digital photography and video. Because our services may be used in many new applications, it is difficult to forecast demand. If demand is lower than expected, we may have excess capacity, which may adversely affect our financial results. If demand is higher than expected, we may be unable to fill all of the orders we receive, which may result in the loss of customers.

If we do not meet conditions to receive the Israeli government grants and tax benefits approved for Fab 2, we may be required to seek alternative financing sources.

In connection with Fab 2, we received approval for grants and tax benefits from the Investment Center of the government of Israel under its Approved Enterprise Program. Under the terms of the approval, we are eligible to receive grants of 20% of up to $1.25 billion invested in Fab 2 plant and equipment, or an aggregate of up to $250 million. As of December 29, 2003, we have received approximately $118 million in grants from the Investment Center. The Investment Center requires that we complete our Fab 2 investments and achieve full production capacity of 33,000 wafer starts per month by the end of 2005, and Israeli law limits the ability of the Investment Center to extend this time limitation, unless an exempting amendment to this law is adopted by the Israeli parliament. We have notified the Investment Center of our revised investment schedule and lower than initially projected expectations for Fab 2 sales; this information is currently being evaluated by the Investment Center. While the Investment Center has continued to fund the grant to us under our Approved Enterprise Program, we cannot assure you that it will continue to do so if it does not accept our revised investment schedule. In addition, even if the Investment Center accepts our revised schedule, any failure by us to meet the conditions of our grant may result in the cancellation of all or a portion of our grants and tax benefits and in the Investment Center requiring us to repay all or a portion of previous grants, which total $118 million as of December 29, 2003. If this were to happen, we would be required to seek alternative financing sources to complete the ramp-up of Fab 2, which may have an adverse effect on our operations.

If we do not attract additional customers, our business will be adversely affected.

For the first nine months of 2003, approximately 64% of our business was generated by four customers, National Semiconductor (26%), Motorola, (15%), FillFactory (12%) and SanDisk (11%). We expect to continue to receive a significant portion of our revenue from a limited number of customers, with SanDisk, our largest Fab 2 customer, accounting for a significant portion of the revenues we expect to generate from Fab 2 in 2004. In the third quarter of 2003, SanDisk was instrumental in ramping up our business and accounted for approximately 80% of our Fab 2 revenues. While we currently expect that SanDisk will continue to be a significant customer of Fab 2, the percentage of Fab 2 revenues represented by sales to SanDisk is expected to decrease as additional customers commence or increase their purchase orders following the qualification of their products in Fab 2. Loss or cancellation of business from, or decreases in, the sales volume or sales prices to these customers including SanDisk could seriously harm our financial results and business. Since the sales cycle for our services typically exceeds one year, if our customers order significantly fewer wafers than forecasted, we will have excess capacity that we may not be able to sell in a short period of time, resulting in lower utilization of our facilities. We may have to reduce prices in order to try to sell the excess capacity. In addition to the revenue loss that could result from unused capacity or lower sales prices, we might have difficulty adjusting our costs to reflect the lower revenues, which could harm our financial results.

11




If we do not receive orders from our wafer partners and technology providers we may have excess capacity.

We have entered into wafer partner agreements and agreements with technology providers under which we have committed a portion of our Fab 2 capacity for future orders from these parties. During the ramp-up of Fab 2, our capacity commitments are limited to approximately 50% of our Fab 2 capacity. These parties are generally not obligated to utilize or pay for all or any portion of their allocated capacity, and generally must confirm their orders to us only three months in advance. If these parties do not place orders with us, we may have unutilized capacity, which we may be unable to fill and could harm our financial results. In addition, in connection with their investments in the Fab 2 project, our wafer partners have been issued credits which may be used to reduce the cash amounts to be paid by them when paying for wafers manufactured in Fab 2. Our major wafer partners have recently agreed to defer the use of their credits until 2007.

If we do not maintain and develop our technology processes and services, we will lose customers and may not be able to attract new ones.

The semiconductor market is characterized by rapid change, including the following:

rapid technological developments;
evolving industry standards;
changes in customer requirements;
frequent new product introductions and enhancements; and
short product life cycles with declining prices as products mature.

In order to maintain our current customer base and attract new customers, we must continue to advance our manufacturing process technologies. We are developing and introducing to production specialized process technologies. We have also licensed 0.18-micron technology from Toshiba and have begun the transfer of 0.13-micron technology from Motorola. We are also working on other independent and joint development projects of technologies for Fab 2. Our ability to achieve and maintain profitable operations depends on the successful development and introduction to production of these processes.

If we do not compete effectively, we will lose business to our competitors.

The semiconductor foundry industry is highly competitive. We compete with approximately 10 independent dedicated foundries, all of which are located in Asia-Pacific, including new foundries based in Taiwan, China, Korea and Malaysia, and with over 20 integrated semiconductor and end-product manufacturers that allocate a portion of their manufacturing capacity to foundry operations. The foundries with which we compete benefit from their close proximity to other companies involved in the design and manufacture of ICs. Many of our competitors have one or more of the following competitive advantages over us:

greater manufacturing capacity;
multiple and more advanced manufacturing facilities;
more advanced technological capabilities;
a more diverse and established customer base;
greater financial, marketing, distribution and other resources; and/or
a better cost structure.

If we do not compete effectively, our results of operations will be materially affected.

We have a large amount of debt, which could have significant negative consequences.

As of December 29, 2003, we had $441 million of bank debt. Our current and future indebtedness could have significant negative consequences, including:

requiring the dedication of a substantial portion of our expected cash flow from operations to service our indebtedness;
increasing our vulnerability to general adverse economic and industry conditions;
limiting our ability to obtain additional financing;
limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we compete;

12




placing us at competitive disadvantage to less leveraged competitors and competitors that have better access to capital resources; and
affecting our abilities to make interest payments on our indebtedness.

If we fail to satisfy the covenants set forth in our amended credit facility, our banks will be able to call our loans.

Our credit facility requires that we maintain certain financial, capital raising and production milestone covenants. In the past, we failed to meet certain of the requirements of the credit facility. We cannot assure you that we will be successful in satisfying these covenants in the future. Any failure by us to observe covenants or satisfy conditions under the credit facility, some of which are not in our control, may result in the banks accelerating our obligations, which would obligate us to immediately repay all loans made by the banks plus penalties, and the banks would be entitled to exercise the remedies available to them under the credit facility, including enforcement of their lien against all our assets. This would have a material adverse effect on our company.

Israeli banking laws may impose restrictions on the total debt that we may borrow from our banks.

Pursuant to a recent amendment to a directive published by the Israel Supervisor of Banks, which becomes effective on March 31, 2004, we may be deemed part of a group of borrowers comprised of the Ofer Brothers Group, The Israel Corporation, and other companies which are also included in such group of borrowers pursuant to the directive, including companies under the control or deemed control of these entities. The directive provides that an entity will be subject to limitations on the amount of bank financing available to it if such entity is included within a group of borrowers, to which the amount of debt financing that has been extended from such bank amounts to 30% of such bank's capital, or is a member of one of the bank's six largest borrowers or groups of borrowers to which, collectively, the amount of debt financing that has been extended from a bank amounts to 150% of such bank's capital (gradually reduced to 135% between April 2005 and June 2006). Should our banks exceed these limitations, they may limit our ability to draw on our remaining Fab 2 bank facility ($69 million) and may require us to return some or all of our outstanding borrowings (which were $441 million as of December 29, 2003), each of which may have a material adverse effect on our business, financial condition and results of operations. The directive provides that a bank may request that the Israel Supervisor of Banks exempt certain entities from the scope of the definition of a group of borrowers. Since we do not know whether the directive will impact us, we do not currently intend to request that our banks seek an exemption on our behalf from the Israel Supervisor of Banks. Should we decide to make such a request of our banks, there can be no assurance that our banks would agree to request an exemption from the Israel Supervisor of Banks on our behalf or that the Israel Supervisor of Banks would grant an exemption, if requested.

If we experience difficulty in achieving acceptable device yields, product performance and delivery times as a result of manufacturing problems, our business will be adversely affected.

The process technology for the manufacture of semiconductor wafers is highly complex, requires advanced and costly equipment and is constantly being modified in an effort to improve device yields, product performance and delivery times. Microscopic impurities such as dust and other contaminants, difficulties in the production process, defects in the key materials and tools used to manufacture a wafer and other factors can cause wafers to be rejected or individual semiconductors on specific wafers to be non-functional. We have from time to time experienced production difficulties that have caused delivery delays or returns and lower than expected device yields. We may also experience difficulty achieving acceptable device yields, product performance and product delivery times in the future as a result of manufacturing problems. Any of these problems could seriously harm our financial results and business.

If our new chief executive officer is unable to fully transition into his new position, our operations will be adversely affected.

Our former co-chief executive officers left us in June 2003, after ten years of service. Our new chief executive officer took office in July 2003. If our new chief executive officer is unable to fully

13




transition into his new position, our operations will be adversely affected.

If we are unable to purchase equipment and raw materials, we will not be able to manufacture our products in a timely fashion, which may result in a loss of existing and potential new customers.

To complete the ramp-up of our Fab 2 facility and to maintain the quality of production in our facilities, we must procure new equipment. In periods of high market demand, the lead times from order to delivery of manufacturing equipment could be as long as 12 to 18 months. In addition, our manufacturing processes use many raw materials, including silicon wafers, chemicals, gases and various metals. Manufacturing equipment and raw materials generally are available from several suppliers. In many instances, however, we purchase equipment and raw materials from a single source. Although supplies for manufacturing equipment and raw materials are adequate, shortages could occur due to an interruption of supply or increased industry demand. Any such shortages could result in production delays that could have a material adverse effect on our business and financial condition.

We must continue to reduce our exposure to currency exchange and interest rate fluctuations, or our cost of operations will increase.

Almost all of our cash generated from operations and from our financing and investing activities is denominated in dollars and New Israeli Shekels, or NIS. Our expenses and costs are denominated in NIS, dollars, Japanese Yen and Euros. We are, therefore, exposed to the risk of currency exchange rate fluctuations.

Our borrowings, including the loans contemplated under our Fab 2 credit facility, provide for interest based on a floating LIBOR rate, and we are therefore subject to exposure to interest rate fluctuations. Furthermore, if our banks incur increased costs in financing our Fab 2 credit facility due to changes in law or the unavailability of foreign currency, our banks may exercise their right to increase the interest rate on our Fab 2 credit facility as provided for in the credit facility, as they did pursuant to its recent amendment.

We regularly engage in various hedging strategies to reduce our exposure to some, but not all, of these risks and intend to continue to do so in the future. However, despite any such hedging activity, we are likely to remain exposed to interest rate and exchange rate fluctuations, which may increase the cost of our activities and, following the ramp-up of Fab 2, will increase our financing expenses.

We depend on intellectual property rights of third parties and failure to maintain or acquire licenses could harm our business.

We depend on third party intellectual property in order for us to provide foundry and design services to our clients. We believe that we are in compliance with the licensing agreements with the owners of these rights and that the licensing agreements adequately protect our rights. If problems or delays arise with respect to the timely development, quality and provision of such intellectual property to us, our customers' design and production could be delayed, resulting in underutilization of our capacity. Failure to maintain or acquire licenses could harm our business. In addition, license fees and royalties payable under these agreements may impact our margins and operating results.

Failure to comply with the intellectual property rights of third parties or defend our intellectual property rights could harm our business.

Our ability to compete successfully depends on our ability to operate without infringing on the proprietary rights of others and defend our intellectual property rights. Because of the complexity of the technologies used and the multitude of patents, copyrights and other overlapping intellectual property rights, it is often difficult for semiconductor companies to determine infringement. Therefore, the semiconductor industry is characterized by frequent litigation regarding patent, trade secret and other intellectual property rights. There are no lawsuits currently pending against us regarding the infringement of patents or intellectual property rights of others. However, we have been a party to such claims in the past and because of the nature of the industry, we may continue to receive such claims in the future. We and some of our customers have recently received a notice from a technology company claiming that we and our customers are infringing its patent rights. This notice was followed by an offer to license the technology

14




company's patents for an immaterial one-time license payment, and we entered into a license agreement with this company. All other prior claims against us have been resolved through license agreements, the terms of which have not had a material effect on our business. One of these agreements expires at the end of 2005, and we may be unable to extend or renew it on similar terms. In the event any third party were to assert infringement claims against us or our customers, we may have to consider alternatives including, but not limited to:

•  negotiating cross-license agreements;
•  seeking to acquire licenses to the allegedly infringed patents, which may not be available on commercially reasonable terms, if at all;
•  discontinuing using certain process technologies, architectures, or designs, which could cause us to stop manufacturing certain ICs if we were unable to design around the allegedly infringed patents;
•  fighting the matter in court and paying substantial monetary damages in the event we were to lose; or
•  seeking to develop non-infringing technologies, which may not be feasible.

Any one or several of these developments could place substantial financial and administrative burdens on us and hinder our business. Litigation, which could result in substantial costs to us and diversion of our resources, may also be necessary to enforce our patents or other intellectual property rights or to defend us or our customers against claimed infringement of the rights of others. If we fail to obtain certain licenses and if litigation relating to alleged patent infringement or other intellectual property matters occurs, it could prevent us from manufacturing particular products or applying particular technologies, which could reduce our opportunities to generate revenues.

As of December 29, 2003, we held 48 patents worldwide. We intend to continue to file patent applications when appropriate to protect our proprietary technologies. The process of seeking patent protection may take a long time and be expensive. We cannot assure you that patents will be issued from pending or future applications or that, if patents are issued, they will not be challenged, invalidated or circumvented or that the rights granted under the patents will provide us with meaningful protection or any commercial advantage. In addition, we cannot assure you that other countries in which we market our services will protect our intellectual property rights to the same extent as the United States. Further, we cannot assure you that we will at all times enforce our patents or other intellectual property rights or that the rights granted under our patents will provide us with a commercial advantage, which could reduce our opportunities to generate revenues.

We could be seriously harmed by failure to comply with environmental regulations.

Our business is subject to a variety of laws and governmental regulations in Israel relating to the use, discharge and disposal of toxic or otherwise hazardous materials used in our production processes. We are currently operating under a conditional permit from the Israeli Ministry of Environmental Affairs concerning the concentration of fluoride in our wastewater. We believe that we are currently in compliance with the terms of our permit, with one exception: we are monitoring the levels of fluoride in accordance with an oral understanding with the Israeli Ministry of Environmental Affairs, which is less frequent than required by the written terms of our permit. If we do not comply with our permit's conditions or with our other understandings with the Ministry, we may be required to allocate financial resources for the implementation of an infrastructure solution in order to be in compliance with all the conditions. We estimate that such an infrastructure solution would be immaterial. While we believe that we currently comply in all other material respects with applicable environmental laws and regulations, if we fail to use, discharge or dispose of hazardous materials appropriately, or if applicable environmental laws or regulations change in the future, we could be subject to substantial liability or could be required to suspend or adversely modify our manufacturing operations.

We may be subject to the risk of loss due to fire because the materials we use in our manufacturing processes are highly flammable.

We use highly flammable materials such as silane and hydrogen in our manufacturing processes

15




and may therefore be subject to the risk of loss arising from fires. The risk of fire associated with these materials cannot be completely eliminated. We maintain insurance policies to reduce losses caused by fire, including business interruption insurance. If any of our fabs were to be damaged or cease operations as a result of a fire, it would reduce manufacturing capacity and reduce revenues.

Possible product returns could harm our business.

Products manufactured by us are subject to return for specified periods if they are defective or otherwise fail to meet customers' specifications. Although we establish what we believe to be reasonable reserves against possible product returns based on our past experience, product returns in excess of such reserves may have an adverse effect on our business and financial condition.

We may be required to repay grants to the Israel Investment Center that we received in connection with Fab 1.

We received grants and tax benefits for Fab 1 under the government of Israel Approved Enterprise program. As of December 31, 2001, we completed our investments under our Fab 1 program and are no longer entitled to any further investment grants for future capital investments in Fab 1. We have agreed that if we do not achieve Fab 1 revenues of $90 million for 2003 and $100 million for 2004 and maintain at Fab 1 at least 600 employees for 2003 and 625 employees for 2004, subject to prevailing market conditions, we will, if demanded by the Investment Center, be required to repay the Investment Center up to approximately $2.5 million. Based on our expected level of Fab 1 revenues and employees for the fourth quarter of 2003, we may be required to repay the Investment Center up to approximately $2.5 million.

We are subject to risks related to our international operations.

In 2003 and 2002, we made substantial sales to customers located in Asia-Pacific and in Europe. Because of our international operations, we are vulnerable to the following risks:

•  we price our products primarily in U.S. Dollars. If the Euro, Yen and other currencies weaken relative to the U.S. Dollar, our products may be relatively more expensive in these regions, which could result in a decrease in our sales;
•  the need to comply with foreign government regulation;
•  general geopolitical risks such as political and economic instability, potential hostilities and changes in diplomatic and trade relationships;
•  natural disasters affecting the countries in which we conduct our business, such as the earthquakes experienced in China, Japan and Taiwan;
•  reduced sales to our customers or interruption in our manufacturing processes in the Pacific Rim that may arise from regional issues in Asia;
•  imposition of regulatory requirements, tariffs, import and export restrictions and other barriers and restrictions;
•  adverse tax rules and regulations;
•  weak protection of our intellectual property rights; and
•  delays in product shipments due to local customs restrictions.

Risks Related to this Offering and our Ordinary Shares

Our stock price may decline after the offering and may be volatile in the future.

The public offering price in this offering will be determined through negotiations between the underwriters and us and may not be indicative of our future market prices. As a result, you may not be able to resell any shares you buy from us at or above the public offering price due to a number of factors, including:

actual or anticipated fluctuations in our operating results;
changes in expectations as to our future financial performance or changes in financial estimates by securities analysts;
developments or disputes concerning patents or proprietary rights;

16




events or announcements relating to our collaborative relationship with others;
investors' perceptions;
volatility in the securities markets;
general conditions in the economy or other external factors;
technological innovations by our competitors; and
the operating and stock price performance of other comparable companies.

In addition, the stock market in general has experienced extreme volatility that often has been unrelated to the operating performance of particular companies. These broad market and industry fluctuations may adversely affect the trading price of our ordinary shares, regardless of our actual operating performance. In particular, the stock prices for many companies in the semiconductor industry have experienced wide fluctuations, which have often been unrelated to the operating performance of such companies. Such fluctuations may adversely affect the market price of our ordinary shares.

Issuance of additional shares pursuant to Fab 2 financing arrangements will dilute the interest of our shareholders; we have also issued warrants to our banks and to one of our shareholders and options to our employees that are exercisable into our ordinary shares below our current market price.

In connection with the Fab 2 project, we have issued to date 39,402,337 ordinary shares to our wafer and equity partners and other shareholders. Upon completion of this offering, we will issue additional shares in connection with the $16.4 million second installment of the fifth and final Fab 2 milestone payments by our wafer and equity partners received in December 2003, based on the price per share in this offering (see "Certain Transactions — Amendment to Fifth Milestone Payment Schedule" for a discussion of the approximate aggregate number of ordinary shares to be issued to our Fab 2 investors with respect to the second installment payment at the offering price to the public in this offering). In January 2001, we issued warrants to our banks exercisable into 400,000 ordinary shares with an exercise price of $6.20. In December 2003, we issued to our banks and to one of our shareholders warrants exercisable into 896,596 and 58,906 ordinary shares, respectively, with an exercise price of $6.17. Up to approximately 8.6 million additional ordinary shares may be issued upon the conversion of our outstanding convertible debentures and upon exercise of warrants held by some of our shareholders, our debentureholders and our Fab 2 contractor.

In addition, we have issued to our employees options to purchase up to 6.8 million shares, of which 3.7 million shares have an exercise price below $7.00. We have also entered into a number of agreements which may result in our issuing large numbers of shares, particularly if we complete the transactions contemplated by these agreements at a time when our share price is low. For example, we have agreed that our wafer partners may elect to convert, on a quarterly basis through 2006, wafer credits we have issued them which may be used to reduce the cash payments to be paid by them when paying for wafers manufactured in Fab 2 into our ordinary shares, based on the average trading price of our ordinary shares during the 15 consecutive trading days preceding the relevant quarter. If our major wafer partners purchase an amount of wafers which would otherwise result in their using the full amount of credits available to them and they elect to convert all of these credits into ordinary shares, we will issue them an aggregate of 8.3 million shares, assuming the average trading price of our ordinary shares during the 15 consecutive trading days preceding the last relevant quarter is $5.00; if the average trading price of our ordinary shares is $10.00, we will issue an aggregate of 4.2 million shares. Issuances of these shares will have a substantial dilutive effect on our shareholders.

Market sales of large amounts of our shares eligible for future sale may lower the price of our ordinary shares.

Of our 51,696,097 outstanding ordinary shares as of December 29, 2003, 11,895,032 are freely tradable and held by non-affiliates, and an additional 1,073,905 shares held by non-affiliates are eligible for sale pursuant to Rule 144 under the Securities Act of 1933, subject to the time, volume and manner of sale limitations of Rule 144. Of these shares, 476,213 and 597,692 shares will be freely tradable under Rule 144(k) by April 2004 and October 2004, respectively. An additional 80,456 and 67,046 shares held by non-affiliates will be eligible for sale under Rule 144(k) by May 2004 and by December 2004, respectively.

In addition, certain of our affiliates (ICTech, SanDisk, Alliance Semiconductor, and Macronix) hold 38,579,658 of our shares, of which 4,086,037

17




are freely tradable and 26,380,558 are currently eligible for sale subject to the time, volume and manner of sale limitations of Rule 144. An additional 4,425,076, 838,082 and 2,849,905 shares held by these affiliates will be eligible for sale under Rule 144 by May 2004, August 2004 and December 2004, respectively, subject to the share transfer restrictions set forth in the shareholders agreement to which they are a party and which remain in effect through January 2008. ICTech and our large wafer partners, as well as our directors and officers, have agreed under written "lock-up" agreements that, for a period of 180 days from the date of this prospectus, they will not sell their shares. Shares purchased by OTPP in 2002 are registered pursuant to an effective shelf registration statement. The sales of large amounts of our ordinary shares (or the potential for those sales even if they do not actually occur) may depress the market price of our ordinary shares. This could also impair our ability to raise capital through the sale of our equity securities.

Our principal shareholders own a controlling interest in us and will be able to exercise it in ways which may be adverse to your interests.

Our wafer partners and ICTech own approximately 75% of our outstanding shares. Under our articles of association, two shareholders holding together 33% of our outstanding shares constitute a quorum for conducting a shareholders meeting. Our wafer partners and ICTech could constitute a quorum for purposes of conducting a shareholders meeting. While we have always solicited proxies from our shareholders prior to our shareholders meetings, we would have a sufficient quorum with two large shareholders even if none of our other shareholders were to participate in our shareholder meetings. If only two large shareholders were to participate in one of our shareholder meetings, these shareholders would determine the outcome of our shareholder meetings without the benefit of the participation of our other shareholders. In addition, even if our other shareholders were to participate in our shareholders meeting in person or by proxy, our wafer partners and The Israel Corporation effectively control our company and may exercise this control in a manner adverse to the interests of our other shareholders.

Risks Related to Our Operations in Israel

Instability in Israel may harm our business.

All of our manufacturing facilities and our corporate and primary sales offices are located in Israel. Accordingly, political, economic and military conditions in Israel may directly affect our business.

Since the establishment of the State of Israel in 1948, a number of armed conflicts have taken place between Israel and its Arab neighbors, as well as incidents of civil unrest. In addition, Israel and companies doing business with Israel have, in the past, been the subject of an economic boycott. Although Israel has entered into various agreements with Egypt, Jordan and the Palestinian Authority, there has been an increase in unrest and terrorist activity, which began in September 2000 and which has continued with varying levels of severity into 2003. Parties with whom we do business have sometimes declined to travel to Israel during periods of heightened unrest or tension, forcing us to make alternative arrangements where necessary. In addition, the political and security situation in Israel may result in parties with whom we have agreements claiming that they are not obligated to perform their commitments under those agreements pursuant to force majeure provisions. We do not believe that the political and security situation has had any material impact on our business to date; however, we can give no assurance that security and political conditions will have no such effect in the future. Any hostilities involving Israel or the interruption or curtailment of trade between Israel and its present trading partners could adversely affect our operations and could make it more difficult for us to raise capital. Furthermore, our manufacturing facilities are located exclusively in Israel, which is currently experiencing civil unrest, terrorist activity and military action. Since we do not have a detailed disaster recovery plan that would allow us to quickly resume manufacturing, we could experience serious disruption of our manufacturing if acts associated with this conflict result in any serious damage to our manufacturing facilities. In addition, our business interruption insurance may not adequately compensate us for losses that may occur, and any losses or damages incurred by us could have a material adverse effect on our business.

Our operations may be negatively affected by the obligations of our personnel to perform military service.

In the event of severe unrest or other conflict, individuals could be required to serve in the military for extended periods of time. In response to the increase in terrorist activity and the renewed Palestinian uprising, there has been

18




a significant call up of military reservists, and it is possible that there will be additional call-ups in the future. Most male Israeli citizens, including our employees, are subject to compulsory military service through middle age. Our operations could be disrupted by the absence for a significant period of time of one or more of our key employees or a significant number of our other employees due to military service. Such disruption could harm our operations.

Our operations may be affected by negative economic conditions in Israel.

Israel has been going in recent years through a period of recession in economic activity, resulting in low growth rates and growing unemployment. Our operations could be adversely affected if the economic conditions in Israel continue to deteriorate. In addition, due to significant economic measures proposed by the Israeli Government, there have been several general strikes and work stoppages in 2003, affecting all banks, airports and ports. These strikes have had an adverse effect on the Israeli economy and on business, including our ability to deliver products to our customers or to receive raw materials from our suppliers in a timely manner. Following the passing by the Israeli Parliament of laws to implement the economic measures, the Israeli trade unions have threatened further strikes or work-stoppages, and these may have a material adverse effect on the Israeli economy and us.

If we do not receive a final business license, we may be required to cease our operations.

The construction of our Fab 2 facility has required us to renew our business license, and we are currently operating under a temporary business license, which will expire at the end of May 2004. We are currently in the process of implementing the conditions for the receipt of a final business license. In the event that we do not receive a final business license, we may be required to pay penalties and if we cannot implement the conditions for the receipt of a final business license, we may be required to modify or cease our operations.

If the exemption allowing us to operate our manufacturing facilities seven days a week is not renewed, our business will be adversely affected.

We operate our manufacturing facilities seven days a week pursuant to an exemption from the law that requires businesses in Israel to be closed from sundown on Friday through sundown on Saturday. This exemption, which has been renewed several times in the past, expires on December 31, 2004. In addition, a significant increase in the number of employees permitted to work under this exemption will be needed as we ramp-up production at Fab 2. We expect the exemption to be renewed, but if the exemption is not renewed and we are forced to close the facility for this period each week, our financial results and business will be harmed.

If we are considered to be a passive foreign investment company, either presently or in the future, U.S. Holders will be subject to adverse U.S. tax consequences.

We will be a passive foreign investment company, or PFIC, if 75% or more of our gross income in a taxable year, including our pro rata share of the gross income of any company, U.S. or foreign, in which we are considered to own, directly or indirectly, 25% or more of the shares by value, is passive income. Alternatively, we will be considered to be a PFIC if at least 50% of our assets in a taxable year, averaged over the year and ordinarily determined based on fair market value and including our pro rata share of the assets of any company in which we are considered to own, directly or indirectly, 25% or more of the shares by value, are held for the production of, or produce, passive income. If we were to be a PFIC, and a U.S. Holder does not make an election to treat us as a "qualified electing fund," or QEF, or a "mark to market" election, "excess distributions" to a U.S. Holder, and any gain recognized by a U.S. Holder on a disposition or our ordinary shares, would be taxed in an unfavorable way. Among other consequences, our dividends would be taxed at the regular rates applicable to ordinary income, rather than the 15% maximum rate applicable to certain dividends received by an individual from a qualified foreign corporation. While we do not believe that we currently are a PFIC, we have not obtained an opinion of counsel confirming this conclusion because it is unclear how the relevant statutory provisions would apply in our circumstances. However, our belief that we are not a PFIC is supported by a private letter ruling issued by the IRS to a company whose circumstances are substantially the same as ours, although such private letter ruling would not be binding on the IRS in determining our status. In addition, the tests for determining PFIC status are applied annually and it is difficult to make accurate predictions of future income and assets, which are relevant to the determination of PFIC status. Accordingly, no assurance can be given that we are not a PFIC or that we will not become a PFIC in the future. If we determine that we have become a PFIC, we will then notify

19




our U.S. Holders and provide them with the information necessary to comply with the QEF rules. If the IRS determines that we are a PFIC for a year with respect to which we have determined that we were not a PFIC, however, it might be too late for a U.S. Holder to make a timely QEF election, unless the U.S. Holder qualifies under the applicable Treasury regulations to make a retroactive (late) election. U.S. Holders who hold ordinary shares during a period when we are a PFIC will be subject to the foregoing rules, even if we cease to be a PFIC, subject to exceptions for U.S. Holders who made a timely QEF or mark-to-market election.

It may be difficult to enforce a U.S. judgment against us, our officers and directors and some of the experts named in this prospectus or to assert U.S. securities law claims in Israel.

We are incorporated in Israel. Most of our executive officers and directors and our Israeli accountants and attorneys are nonresidents of the United States, and a substantial portion of our assets and the assets of these persons are located outside the United States. Therefore, it may be difficult to enforce a judgment obtained in the United States, against us or any of these persons, in U.S. or Israeli courts based on the civil liability provisions of the U.S. Federal securities laws. Additionally, it may be difficult for you to enforce civil liabilities under U.S. Federal Securities laws in original actions instituted in Israel.

Forward-Looking Statements

The statements incorporated by reference or contained in this prospectus discuss our future expectations, contain projections of our results of operations or financial condition and include other forward-looking information within the meaning of Section 27A of the Securities Act of 1933, as amended. Our actual results may differ materially from those expressed in forward-looking statements made or incorporated by reference in this prospectus. Forward-looking statements that express our beliefs, plans, objectives, assumptions or future events or performance may involve estimates, assumptions, risks and uncertainties. Therefore, our actual results and performance may differ materially from those expressed in the forward-looking statements. Forward-looking statements often, although not always, include words or phrases such as the following: "will likely result," "are expected to," "will continue," "is anticipated," "estimate," "intends," "plans," "projection" and "outlook."

You should not unduly rely on forward-looking statements contained or incorporated by reference in this prospectus. Various factors discussed in this prospectus, including, but not limited to, all the risks discussed in "Risk Factors" may cause actual results or outcomes to differ materially from those expressed in forward-looking statements. You should read and interpret any forward-looking statements together with these documents.

Any forward-looking statement speaks only as of the date on which that statement is made. We will not update any forward-looking statement to reflect events or circumstances that occur after the date on which such statement is made.

Use of Proceeds

We estimate that the net proceeds from the sale of the ordinary shares we are offering will be approximately $87.4 million. If the underwriters fully exercise the over-allotment option, the net proceeds of the shares we sell will be $100.6 million. "Net proceeds" is what we expect to receive after paying the underwriting discount and other expenses of the offering. For purposes of estimating net proceeds, we are assuming that the public offering price will be $7.75 per share.

The net proceeds will be used towards the further ramp-up and deployment of Fab 2 and for marketing expenses for the sale of our products and services as well as for general corporate purposes, including working capital.

Dividend Policy

Since 1998, we have not declared or paid cash dividends on any of our shares, and we do not anticipate paying dividends on our ordinary shares in the foreseeable future. The credit facility that we entered into with our banks prohibits the payment of dividends prior to January 1, 2008, and before any such distribution, we must have placed on deposit with our banks an amount equal to the debt service for the quarter in which the distribution is to be made and charged such deposit in favor of our banks, and we must have complied with certain financial ratios. In addition, we may only declare and pay a dividend provided that:

the dividend is only paid from excess cash flow from Fab 2;
there is no event of default outstanding under the credit facility; and
an event of default could not reasonably exist after such distribution.

The Israel Companies Law also restricts our ability to declare dividends. We can only distribute dividends from profits (as defined in the law), provided that there is no reasonable suspicion that the dividend distribution will prevent us from meeting our existing and future expected obligations as they come due.

Management's Discussion and Analysis of
Financial Condition and Results of Operations

The information contained in this section should be read in conjunction with our consolidated financial statements and related notes and the information contained elsewhere in this prospectus. Our financial statements have been prepared in accordance with generally accepted accounting principles ("GAAP") in Israel. Material differences between Israel GAAP and US GAAP as they relate to our financial statements are described in Note 20 to our consolidated audited annual financial statements and in Note 5 to our unaudited consolidated financial statements contained elsewhere in this prospectus.

Overview

We are a pure-play independent wafer foundry dedicated to the manufacture of semiconductors. Pure-play foundries do not offer any products of their own, but focus on producing ICs based on the design specifications of their customers. We manufacture semiconductors using advanced production processes for our customers primarily based on third party designs and our own proprietary designs. We currently manufacture integrated circuits, or ICs, with geometries ranging from 1.0 to 0.18 microns and plan to initiate volume production in geometries of 0.13 microns during 2005.

Our primary source of revenue is from the fabrication of ICs using CMOS process technology. We are currently focused on the emerging opportunities involving CMOS image sensors, embedded flash and mixed-signal technologies. ICs manufactured by us are incorporated into a wide range of products in diverse markets, including consumer electronics, personal computer and office equipment, communications, automotive, professional photography and medical device products.

The primary customers for our products are fabless IC companies and integrated device manufacturers, or IDMs. Most of our product sales are made pursuant to long-term contracts with our customers, under which we have agreed to reserve manufacturing capacity at our production facilities. Our sales cycle is generally 18-24 months for new customers and can be as short as 9-12 months for existing customers. The typical stages in the sales process, from initial contact until production, are: technical evaluation; photomask design specification; silicon prototyping; assembly and testing; validation and qualification; and production.

During the nine months ended September 30, 2003, National Semiconductor, Motorola, FillFactory and SanDisk contributed 26%, 15%, 12% and 11% of our revenues, respectively. In 2002, National Semiconductor, Matsushita and Motorola contributed 31%, 16% and 13% of our revenues, respectively. In 2001, National Semiconductor and Motorola contributed 30% and 17% of our revenues, respectively. In 2004, we expect that SanDisk, our largest Fab 2 customer, will account for a significant portion of our Fab 2 revenues. In the third quarter of 2003, SanDisk was instrumental in ramping up our business and accounted for approximately 80% of our Fab 2 revenues. While we currently expect that SanDisk will continue to be a significant customer of Fab 2, the percentage of Fab 2 revenues represented by sales to SanDisk is expected to decrease as additional customers commence or increase their purchase orders following the qualification of their products in Fab 2. As foundry utilization rates peak with the industry recovery, we expect to attract additional customers as available capacity decreases worldwide, including at leading Asian foundries.

In addition to further developing our customer base, we have also made a concentrated effort to expand the geographical diversity of our sales. The percentage of our sales from customers located outside the United States was 10%, 31%, 38% and 28% in the years ended December 31, 2000, 2001 and 2002 and the nine months ended September 30, 2003, respectively. As we have successfully expanded our customer base with customers located in Asia-Pacific and in Europe, we believe that a substantial portion of our sales will continue to come from customers located outside the United States.

Our Company was founded in 1993, when we acquired National Semiconductor's 150-mm wafer fabrication facility, or Fab 1, and commenced operations as an independent foundry with a production

26




capacity of approximately 5,000 wafer starts per month. Since then, we have significantly modernized our facilities and equipment, which has improved our process geometries from 1.0 microns to 0.35 microns and enhanced our process technologies to include CMOS image sensors, embedded flash and mixed-signal technologies. We have also expanded our capacity through increased production in Fab 1 to approximately 16,000 wafer starts per month to meet additional customer demand. Fab 1 has been cash flow positive for the past six quarters.

We recently completed the construction of the building and infrastructure and commenced the initial ramp-up of a second manufacturing facility, or Fab 2. Fab 2 is designed to operate in geometries of 0.18 microns and below, using advanced materials and advanced CMOS technology licensed from Motorola and Toshiba, as well as other technologies that we might acquire or develop independently. We began volume production at Fab 2 during the third quarter of 2003. Production capacity as of the end of December 2003 was 8,500 wafer starts per month, and we currently expect to have production capacity ranging between 13,000 and 15,000 wafer starts per month by the end of 2004. When the production ramp is completed, Fab 2 is expected to have the capacity to produce 33,000 200-mm wafer starts per month. While we expect to continue to operate Fab 1, we expect Fab 2 to form the core of our future business.

Critical Accounting Policies

Non-Capitalizable Costs.    In accordance with generally accepted accounting principles, we capitalized through the third quarter of 2003 most of our costs relating to the establishment of Fab 2, primarily for property and equipment and other assets. Following commencement of operations of Fab 2 in the third quarter of 2003, most of the direct costs related to the construction and equipping of Fab 2 and to the transfer of the Fab 2 technologies that were capitalizable until Fab 2 came into production, are no longer capitalizable. Capitalizable Fab 2 costs were only incremental direct costs that related to the establishment and equipping of Fab 2 and to the integration and transfer of technology to be implemented in Fab 2.

Direct internal costs consisted primarily of payroll-related costs, and allocated payroll costs, on the basis of management's estimates and assumptions and methodologies, including timesheet inputs. Most of the capitalized payroll-related costs consisted of wages to employees dedicated solely to the establishment of Fab 2. In addition, other direct related expenses such as import costs, transportation, installation and consulting fees were also capitalized. Under different assumptions relating to these costs and their being attributable to the Fab 2 project, the classification of these costs may be different, which may significantly affect our financial position and results of operations. The effect, if any, under Israel GAAP and US GAAP would be similar.

Revenue Recognition.    In accordance with generally accepted accounting principles, our revenues are recognized upon shipment or as services are rendered when title has been transferred, collectibility is reasonably assured and acceptance criteria are satisfied, based on tests performed prior to customer on-site testing. Prior to commencement of production by us, we and our customers test and pre-approve the prototype, on the basis of which specifications and features the ordered products will be produced. Electronic, functional and quality tests are performed on the products prior to shipment and customer on-site testing. Such testing reliably demonstrates that the products meet all of the specified criteria prior to formal customer acceptance and that product performance upon customer on-site testing can reasonably be expected to conform to the specified acceptance provisions. Our revenue recognition policy is significant because our revenues are a key component of our results of operations. We follow very specific and detailed guidelines in measuring revenue; however an accrual for estimated returns, which is computed primarily on the basis of historical experience, is recorded. Changes in assumptions for determining the accrual for returns may affect mainly the timing of our revenue recognition and cause our operating results to vary from quarter to quarter. Accordingly, our financial position and results of operations may be affected. That effect, if any, under Israel GAAP and US GAAP would be similar.

27




Depreciation and Amortization of Fab 2 Assets.    During the third quarter of 2003, we commenced depreciating the Fab 2 property and equipment and amortizing the 0.18-micron technology, based on the straight-line method. Currently, we estimate that the expected economic life of the Fab 2 assets will be as follows: (i) prepaid perpetual land lease and buildings – 14 to 25 years; (ii) machinery and equipment – 5 years; and (iii) the 0.18-micron technology – 4 years, while amortization will phase in commencing on the dates on which each of the Fab 2 manufacturing lines is ready for use. We expect that the depreciation and amortization expenses relating to Fab 2 facilities will be in 2004 approximately $30 million per quarter due to the Fab 2 ramp-up. Changes in our estimates regarding the expected economic life of Fab 2 assets, or a change in the dates on which each of the Fab 2 manufacturing lines is ready for use, might significantly affect our depreciation and amortization expenses. That effect, if any, under Israel GAAP and US GAAP would be similar.

Impairment of Assets.    In January 2003, the Israeli Accounting Standards Board issued Standard No. 15, "Impairment of Assets," which is effective for financial statements for reporting periods commencing January 1, 2003 or thereafter. This standard addresses the accounting treatment and presentation of impairment of assets, and establishes procedures to be implemented in order to ensure that assets are not presented in amounts exceeding their recoverable value. Though according to US GAAP, e.g. FASB 144 and FASB 142, recoverability tests are performed based on undiscounted expected cash flows, Standard No. 15 indicates that an asset's recoverable value is the higher of the asset's net selling price and the asset's value in use, the latter being equal to the asset's discounted expected cash flows. While the adoption of the provisions of Standard No. 15 as of September 30, 2003, had no effect on our financial position and results of operations as of such date, the use of different assumptions with respect to the expected cash flows from our assets and other economic variables, primarily the discount rate, may lead to different conclusions regarding the recoverability of our assets' carrying values and to the potential need to record an impairment loss for our long-lived assets.

Recent Accounting Pronouncements under US GAAP as They Apply to Us

Rescission and Amendments of Certain SFASs.    In April 2002, the Financial Accounting Standard Board, or FASB, issued Statement of Financial Accounting Standards No. 145 "Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13 and Technical Corrections" ("SFAS 145"). SFAS 145 rescinds, amends and clarifies certain previous standards related primarily to debt extinguishments and leases. SFAS 145 eliminates the requirement that gains and losses from the extinguishments of debt be aggregated and classified as an extraordinary item. The rescission of SFAS No. 4 is effective for fiscal years beginning after May 15, 2002. The remainder of SFAS 145 is generally effective for transactions occurring after May 15, 2002. Adoption of SFAS 145 did not have and is not expected to have any material impact on our financial position and results of operations.

Accounting for Costs Associated with Exit or Disposal Activities.    In July 2002, the FASB issued Statement of Financial Accounting Standards No. 146, "Accounting for Costs Associated with Exit or Disposal Activities" ("SFAS 146"). SFAS 146 supersedes EITF No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)." SFAS 146 requires companies to recognize costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to an exit or disposal plan, as required by EITF 94-3. SFAS 146 is effective for exit or disposal activities that are initiated after December 31, 2002, with early application encouraged. Adoption of SFAS 146 did not have any impact on our financial position and results of operations.

Accounting for Stock-Based Compensation — Transition and Disclosure — an Amendment of FASB Statement No. 123.    In December 2002, the FASB issued Statement of Financial Accounting Standards Board No. 148, "Accounting for Stock-Based Compensation — Transition and Disclosure — an amendment of FASB Statement No. 123" ("SFAS 148"). SFAS 148 amends SFAS No. 123 to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS 148 amends the disclosure requirements of SFAS 123 to require prominent disclosures in both annual and interim

28




financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. We have followed the prescribed format and have provided the additional disclosures required by SFAS 148 in the financial statements contained elsewhere in this prospectus for the periods presented and have provided the disclosures in our quarterly reports containing condensed financial statements for interim periods commencing the quarter ended March 31, 2003.

Amendment of SFAS 133.    In May 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133 on Derivative Instruments and Hedging Activities." SFAS No. 149 amends and clarifies accounting for derivative instruments including certain derivative instruments embedded in other contracts and hedging activities under SFAS No. 133. It is effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003. The adoption of this standard had no impact on our financial position or results of operations.

Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity.    In May 2003, the FASB issued SFAS No. 150, "Accounting For Certain Financial Instruments with Characteristics of Both Liabilities and Equity" which establishes standards for how an issuer of financial instruments classifies and measures certain financial instruments with characteristics of both liabilities and equity. SFAS 150 requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in some circumstances) if, at inception, the monetary value of the obligation is based solely or predominantly on a fixed monetary amount known at inception, variations in something other than the fair value of the issuer's equity shares or variations inversely related to changes in the fair value of the issuer's equity shares. This statement is effective in connection with our activities for financial instruments entered into at the beginning of the third quarter of 2003. The adoption of SFAS 150 had no impact on our financial position and results of operations.

FIN 45.    In November 2002, the FASB issued FASB Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others" ("FIN 45"). This interpretation requires elaborating on the disclosures that must be made by a guarantor in its interim and annual financial statements about its obligations under certain guarantees that it has issued. It also clarifies that a guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. The disclosure requirements of FIN 45 are effective for financial statements issued after December 15, 2002 and its recognition requirements are applicable for guarantees issued or modified after December 31, 2002. The adoption of FIN 45 had no impact on our financial position and results of operations.

FIN 46.    In January, 2003, the FASB issued FASB Interpretation No. 46, "Consolidation of Variable Interest Entities" ("FIN 46"). This Interpretation of Accounting Research Bulletin No. 51, "Consolidated Financial Statements,"addresses consolidation by enterprises of variable interest entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional support from other parties. FIN 46 applies immediately to variable interest entities created after January 31, 2003, and to variable interest entities in which an enterprise obtains an interest after that date. With respect to variable interest entities, if any, in which we hold a variable interest acquired before February 1, 2003, the guidance in FIN 46 is in effect for our financial statements beginning July 1, 2003. The adoption of FIN 46 had no impact on our financial position and results of operations.

Recent Accounting Pronouncements under Israel GAAP as They Apply to Us

Impairment of Assets According to Standard No. 15 of the Israeli Accounting Standards Board.    In January 2003, the Israeli Accounting Standards Board issued Standard No. 15, "Impairment of Assets". This standard is the initial formal accounting pronouncement in Israel addressing the accounting treatment and presentation of impairment of assets, which establishes procedures to be implemented in order to ensure that assets are not presented in amounts exceeding their recoverable

29




value. An asset's recoverable value is the higher of the asset's net selling price and the asset's value in use, the latter being equal to the asset's discounted expected cash flows. Prior to issuing Standard No. 15, we tested the recoverability of our assets based on undiscounted expected cash flows, a method that under Standard No. 15 will no longer be acceptable. Initial application of this standard will generally be on a prospective basis. Standard No. 15 is effective for financial statements for reporting periods commencing January 1, 2003 or thereafter, with early application encouraged. The adoption of the provisions of Standard No. 15 as of December 31, 2002 and September 30, 2003, would not have a material effect on our financial position and results of operations as of such dates.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the interim financial statements and the related notes thereto.

Results of Operations

Nine Months Ended September 30, 2003 Compared To Nine Months Ended September 30, 2002

Sales.    Sales in the nine months ended September 30, 2003 increased by 14.7% to $41.5 million from $36.2 million in the comparable 2002 period. This increase was attributable to higher wafer shipments in Fab 1, which resulted in increased Fab 1 sales of $3.9 million, and a $1.4 million increase in Fab 2 revenues from the sales of Fab 2 wafer products, in comparison to $4 million in the comparable period attributable to revenues in Fab 2 associated with our joint development agreement with Matsushita for the development of 0.18-micron embedded microFLASH technology.

Cost of Sales.    Cost of sales in the nine months ended September 30, 2003 was $75.8 million, compared with $50.0 million in the comparable 2002 period. This increase is due mainly to the commencement of Fab 2 operations during 2003, which resulted in higher depreciation and amortization expenses of $17.5 million related to Fab 2, as well as expensing costs amounting to $7.6 million, which were capitalized prior to the commencement of Fab 2 operations.

Gross Loss.    Gross loss in the nine months ended September 30, 2003 was $34.3 million compared to a gross loss of $13.7 million in the comparable 2002 period. The increase in gross loss is primarily attributable to the high level of expenses related to Fab 2 of $38.0 million (mainly due to depreciation and amortization costs of $17.7 million and payroll costs of $8.7 million) in relation to low levels of Fab 2 sales amounting to $5.5 million during this period.

Research and Development.    Research and development expenses in the nine months ended September 30, 2003 increased to $12.6 million from $10.2 million in the comparable 2002 period. The increase was due to increased research and development activities related to the technologies we licensed from Motorola and Toshiba for Fab 2. Research and development expenses are reflected net of participation grants received from the Israeli government ($0.7 million and $0.9 million, respectively).

Marketing, General and Administration.    Marketing, general and administrative expenses in the nine months ended September 30, 2003 increased to $17.1 million from $11.8 million in the comparable 2002 period, primarily due to the expansion of our worldwide marketing and sales efforts in connection with the commencement of production in Fab 2 amounting to $3.9 million.

Operating Loss.    Operating loss in the nine months ended September 30, 2003 was $63.9 million, compared to $35.7 million in the comparable 2002 period, reflecting the increased gross loss of $20.5 million, increased research and development expenses of $2.4 million and increased marketing and sales expenses of $5.3 million incurred in connection with the commencement of production in Fab 2.

Financing Expenses, Net.    Financing expenses in the nine months ended September 30, 2003 were $4.3 million compared to financing expenses of $2.1 million in the comparable 2002 period. This increase is due to the expensing of interest costs on loans and convertible debentures totaling $4.1 million that were capitalized prior to the commencement of operations of Fab 2 in the third quarter of 2003 and offset by exchange rate differences of $1.9 million. Financing expenses, net, in the nine

30




months ended September 30, 2003 exclude interest costs of $9.1 million in connection with the establishment of Fab 2 that were capitalized to property and equipment, compared to $7.4 million in the comparable 2002 period.

Loss.    Our loss in the nine-month period ended September 30, 2003 was $68.3 million, compared to $37.8 million in the comparable 2002 period. This increase is primarily attributable to the increased operating loss of $28.2 million and increased financing expenses, net of $2.2 million.

Year Ended December 31, 2002 Compared To Year Ended December 31, 2001

Sales. Sales in 2002 decreased by 1.1% to $51.8 million from $52.4 million in 2001. This decrease is attributable to 10% lower wafer shipments in Fab 1 as well as a reduction of 9% in the average price per wafer in Fab 1 as a result of weakening demand in the semiconductor industry that was offset by $8 million in revenue associated with our joint development agreement with Matsushita for the development of 0.18-micron embedded micro-FLASH technology in Fab 2.

Cost of Sales.    Cost of sales in 2002 was $67.0 million, compared with $76.7 million in 2001. A decrease of $21.5 million in the cost of sales of Fab 1 was attributable to cost saving initiatives that were implemented in Fab 1, offset by fixed manufacturing costs and increased uncapitalized expenses of $11.8 million related to the establishment of Fab 2.

Gross Loss.    Gross loss in 2002 was $15.2 million compared with a gross loss of $24.4 million in 2001. Our gross loss in 2002 was lower than our gross loss in 2001 due to reduced gross loss in Fab 1 of $12.9 million resulting from reduced sales and cost savings activities offset by our increased gross loss in Fab 2 of $3.8 million, which resulted from $10.0 million in increased uncapitalized expenses related to the establishment of Fab 2 offset by $6.2 million in gross profits from the joint development agreement with Matsushita.

Research and Development.    Research and development expenses in 2002 increased to $17.0 million from $9.6 million in 2001. The increase was due to increased research and development activities for technologies to be implemented in Fab 2. Research and development expenses are reflected net of participation grants received from the Israeli government ($1.2 million and $1.4 million, respectively).

Marketing, General and Administration.    Marketing, general and administrative expenses in 2002 increased to $17.1 million from $14.5 million in 2001 due to higher deployment for Fab 2 activities of $2.5 million and higher marketing efforts among new and potential Fab 2 customers during 2002 amounting to $2.7 million offset by $2.6 million decreased sales, general and administration expenses related to Fab 1.

Operating Loss.    Operating loss in 2002 was $49.3 million, compared to $48.4 million in 2001. The increase was due to $7.5 million in higher research and development expenses in connection with Fab 2, as well as $2.6 million in higher marketing expenses, offset by $9.1 million in lower gross loss.

Financing Income (Expenses), Net.    Financing expenses in 2002 were $2.1 million compared with $1.5 million financing income in 2001. The majority of our financing costs in 2002 and 2001, amounting to $11.0 million and $2.3 million, respectively, were not included in our results of operations since they were capitalized to Fab 2 assets during the establishment of Fab 2. The capitalized financing expenses were primarily comprised of bank loans interest, amounting to $10.6 million and $1.5 million, respectively, as well as expenses in 2002 related to convertible debentures, amounting to $ 1.2 million. In 2001, non-capitalized financial expenses were offset by financial income, primarily attributable to bank interest on proceeds from our Fab 2 investors, resulting in net financial income, while in 2002, financial expenses exceeded financial income due to the decrease in cash and cash equivalents.

Other Income, Net.    Other income, net, in 2002 was $0.045 million, compared to other income, net, of $8.4 million in 2001, due to the sale of our shareholding in Virage Logic in 2001 for a capital gain of $9.5 million, offset by a $1.1 million write off of our investment in Azalea Microelectronics in 2001.

Taxes on Income.    Due to our recent history of operating losses, in 2002 and 2001 we established valuation allowances against all deferred tax assets, except with respect to existing deferred tax liabilities; therefore, we recognized no income tax benefit attributable to our net operating loss.

31




Loss.    Our loss in 2002 was $51.4 million compared to a loss of $38.5 million in 2001. The increased loss was primarily attributable to the increase in our Fab 2 operating loss of $19.4 million, comprised of increased non-capitalized expenses, research, development and marketing expenses, and offset by the $9.5 million capital gain generated from the sale of our holdings in Virage Logic.

Year Ended December 31, 2001 Compared To Year Ended December 31, 2000

Sales.    Sales in 2001 decreased by 50% to $52.4 million from $104.8 million in 2000. The decrease in 2001 is primarily attributable to 52.8% lower wafer shipments in Fab 1, compared to 2000, as a result of weakening demand in the semiconductor industry.

Cost of Sales.    Cost of sales in 2001 was $76.7 million, compared with $88.8 million in 2000. The decrease in 2001 was primarily attributable to the lower utilization of Fab 1. Although our sales reduced by 50%, we were only able to reduce our cost of sales in Fab 1 by 17.7% due to our high level of fixed manufacturing costs mainly related to depreciation and amortization and payroll expenses and due to our Fab 2 non-capitalized expenses amounting to $3.8 million.

Gross Profit (Loss).    Gross loss in 2001 was $24.4 million, compared with a gross profit of $16.0 million in 2000. This gross loss in 2001 is primarily attributable to our reduced sales by $52.4 million partially offset by $12.1 million in reduced cost of sales.

Research and Development.    Research and development expenses in 2001 were $9.6 million, compared with $9.0 million in 2000. The slight increase in research and development in 2001 was due to our high level of research activity in connection with new technologies to be implemented in Fab 2. Research and development expenses are reflected net of participation grants received from the Israeli government ($1.4 million and $1.3 million, respectively).

Marketing, General and Administration.    Marketing, general and administrative expenses in 2001 increased to $14.5 million, compared to $11.4 million in 2000. The increase in 2001 was primarily attributable to an increase of $1.5 million in recruitment and training expenses, in addition to an increase of $1.8 million in Fab 2 marketing efforts.

Financing Income, Net.    Financing income, net, in 2001 was $1.5 million compared with $1.4 million in 2000. The slight increase in our financing income was due to interest income on proceeds received from our Fab 2 investors offset by higher levels of interest expenses on our increased Fab 1 credit facility. In 2001, $2.3 million of financing expenses, net, were capitalized to Fab 2 assets, comprised mainly of $1.5 million in interest expenses on bank loans, while no such expenses were incurred in 2000.

Operating Loss.    Operating loss in 2001 increased to $48.4 million from $4.4 million in 2000. The increased operating loss in 2001 was primarily attributable to increased gross losses in Fab 1 amounting to $36.7 million and Fab 2 non-capitalized expenses amounting to $14.4 million.

Other Income (Expense), Net.    Other income, net, in 2001 was $8.4 million compared to other expense of $0.5 million in 2000 due to the sale of our holdings in Virage Logic generating a capital gain of $9.5 million, offset by a $1.1 million write-off of our investment in Azalea Microelectronics.

Income Taxes (Benefit).    Due to our recent history of operating losses, in 2001 and 2000 we established valuation allowances against all deferred tax assets, except with respect to deferred tax liabilities; therefore, we recognized no income tax benefit attributable to the net operating loss. In 2000, we entered into a final settlement agreement with the Israeli tax authorities for the years 1993-1998, pursuant to which we incurred an expense of $0.5 million.

Loss.    The loss in 2001 was $38.5 million, compared to a loss of $4.0 million in 2000. The loss in 2001 was primarily attributable to an increased operating loss of $44.0 million, offset by the $9.5 million capital gain generated from the sale of our holdings in Virage Logic.

Liquidity and Capital Resources

At September 30, 2003, we had an aggregate of $8.4 million in cash, cash equivalents, and short-term interest-bearing deposits, of which $1.7 million was contractually restricted for Fab 2 use only. This

32




compares to $69.7 million in cash, cash equivalents, and short-term and interest-bearing deposits, of which $51.3 million was contractually restricted for Fab 2 use only, as of December 31, 2002.

During the nine months ended September 30, 2003, we generated cash from the following sources: $94.0 million from bank loans, net of $3 million in repayments; $15.8 million net proceeds from our issuance of ordinary shares; and $27.8 million from Investment Center grants. During the nine months ended September 30, 2003, we invested $161.5 million in construction, equipment and other assets of Fab 2, primarily in connection with our purchase and transfer of technology from Motorola and Toshiba and construction and equipping of Fab 2. Fab 2 operating expenses are expected to result in negative cash flow from operating activities through the end of 2003.

As of September 30, 2003, we had $10.0 million of loans under our Fab 1 facility, which will be repaid and terminated in December 2003.

We recently completed the construction of the building and infrastructure and commenced the initial ramp-up of Fab 2, our new advanced wafer facility adjacent to Fab 1 in Migdal Haemek, Israel and have begun wafer production for our customers in Fab 2 during the third quarter of 2003. Production capacity at the end of December 2003 was 8,500 wafer starts per month. We currently expect to have production capacity ranging between 13,000 and 15,000 wafer starts per month by the end of 2004. When the ramp-up is completed, Fab 2 is expected to have the capacity of 33,000 200-mm wafer starts per month. We expect to complete our ramp-up of Fab 2 by December 2006. We expect the total cost of the construction, equipping of the Fab 2 facility and ramp-up of production will be approximately $1.5 billion. As of December 29, 2003, we received a total of $941 million for the Fab 2 project. The remainder of the Fab 2 project can be funded by additional grants available from the Investment Center, debt financing made available from our banks, sales of our securities, proceeds from the sale of securities we own in certain companies, including Saifun Semiconductors, wafer prepayments from our customers, payments we receive from Matsushita and cash flow from operations.

We expect to have adequate liquidity for our Fab 2 activities in 2004. In 2004, we expect to make capital investments of approximately $160 million in Fab 2 and to have negative cash flow from Fab 2 operations of approximately $40 million. We expect to fund our Fab 2 activities during 2004 from the following sources: (1) additional loans under the Fab 2 credit facility, $69 million; (2) Investment Center grants, approximately $30 million; and (3) sales of our securities, including the proceeds of this offering.

The following chart illustrates the various financial sources available to us to fund the construction and ramp-up to completion of Fab 2, the amounts received to date and the amounts expected or required to be received from various sources:

Credit facility   431     69 (2)(4)    500  
Other financing sources   86     152 (3)(4)    238  
(1) Under the requirements of Israeli Law, we are required to complete our approved investment program for Fab 2 by the end of 2005 (see "— Investment Center Grants"). Failure to meet this requirement may result in the cancellation of all or a portion of our grants. See "Risk Factors — If we do not meet conditions to receive the Israeli government grants and tax benefits approved for Fab 2, we may be required to seek alternative financing sources."
(2) Our banks' obligation to fund the loans is subject to the satisfaction of minimum production capacity milestones, the required maintenance of financial ratios and to additional conditions and covenants (see "Material Agreements — Credit Facility" for a discussion of the amendment to the credit facility with our banks).
(3) Under the amendment to our Fab 2 credit facility, we are required to raise additional financing from specified sources by various prescribed dates and to raise an aggregate amount of $152.0 million by no later than the end of 2005 (see "Material Agreements — Credit Facility"). The proceeds of this offering will be applied toward our compliance with this

33




contractual obligation. If we raise $87.4 million in this offering, the remaining additional financing that we will be required to raise under our credit facility will decrease from $152 million to $64.6 million. We expect to raise this additional funding through: (i) equity investments, including the sale of convertible securities; (ii) proceeds from the sale of securities we own in certain companies, including Saifun Semiconductors Ltd.; (iii) wafer prepayments from customers and (iv) a portion of payments we receive from Matsushita.
(4) We have agreed with our banks and TIC to complete a rights offering on pre-determined terms if we do not complete a required fundraising. This arrangement may result in an increase of our credit facility by up to $43 million.
(5) We will be required to make capital investments and implement and acquire advanced technologies of an aggregate of approximately $1.5 billion in order to ramp-up Fab 2 to 33,000 wafer starts per month. All of our capital investments in 2004 will be made in Fab 2. In addition to the amounts listed in footnote 5 above, we will require additional cash to complete the full ramp-up of Fab 2; we expect to fund these cash needs through cash generated from operations.

We cannot assure you that we will be able to obtain funds from these sources as expected, due to existing or potential defaults under our Fab 2 agreements, poor conditions in capital markets, failure to benefit from a recovery in the semiconductor market, failure to achieve milestones and other factors, which may affect our ability to raise funds. If we do not satisfy our need for funds for Fab 2 or if the timing of the receipt of financing lags behind the timing of expenses, we may from time to time experience lack of liquidity for our activities.

(1) Short-term debt and other current liabilities include our trade accounts payable for equipment and services that have already been supplied.
(2) Long-term debt includes principal and interest payments in accordance with the terms of the credit facility amended in November 2003, as well as the impact of our hedging transactions.
(3) Total amounts include expected principal and interest payments for the presented periods.
(4) These amounts primarily consist of ordered equipment that has not yet been received. In addition to these agreements, we have committed approximately $4.5 million in standby letters of credit and guarantees to secure our Fab 2 construction and equipment obligations.

The above table does not include other categories of obligations or commitments, such as royalty agreements and short-term service agreements for Fab 2. We are unable to reasonably estimate the total amounts to be paid under the terms of these agreements, as the royalties and required services are a function of future sales revenues and the volume of business in Fab 2. We are not a party to any material off-balance sheet arrangements.

Investment Center Grants.    In December 2000, the Israeli government's Investment Center approved an investment program in connection with Fab 2. The approval certificate provides for government grants at a rate of 20% of qualified investments up to $1.25 billion, up to $250 million, subject to customary conditions and other conditions, including a requirement that approximately $400 million of our Fab 2 funding consist of paid-in-capital and that $550 million of our Fab 2 funding will be

34




obtained by way of a credit facility from commercial banks, which was subsequently reduced to $500 million. We have registered a lien on our assets for the benefit of the Investment Center which ranks subordinate to our banks. The approval certificate also provides for a tax holiday on all taxable income related to Fab 2 for the first two years of undistributed profitable operations. As of December 29, 2003, we had received approximately $118 million in grants from the Investment Center, and raised $302.1 million as paid in capital towards the $400 million. As long as we comply with the terms of our grants, we are not required to make royalty payments or other payments under the terms of our Investment Center grants.

Consistent with the requirements of Israeli law, our investment grant requires that we complete our investment program within five years, meaning by no later than the end of 2005. We do not expect to complete our Fab 2 investments and achieve full production capacity of 33,000 wafer starts per month by the end of 2005. Israeli law limits the ability of the investment center to extend the five-year investment limitation, unless an exempting amendment to this law is adopted by the Israeli parliament. We have notified the Investment Center of our revised investment schedule, and it is currently being evaluated by the investment center. We have also informed the investment center of our reduced rate of annual investments and our lower than projected expectations for Fab 2 sales.

Securities Issuances.    Since the beginning of the Fab 2 project, we have completed a series of capital raising transactions. In January 2002, we completed a sale of units in Israel, each composed of convertible unsecured subordinated debentures and options, resulting in net proceeds of approximately $21.5 million. Each debenture is NIS 1 in principal amount, and is adjusted to reflect increases in the Israeli Consumer Price Index and bears interest at a rate of 4.7% per annum, payable yearly commencing January 20, 2003. Principal is payable in four installments beginning in January of 2006 through 2009. Prior to December 31, 2008, the debentures are convertible into ordinary shares at a conversion rate of one ordinary share per NIS 41 principal amount of debentures linked to the Israel Consumer Price Index. As of September 30, 2003, NIS 113,475,535 (or $25.6 million) in convertible debentures, net and 2,211,596 Options (Series 1) were outstanding. In September 2002, we distributed to our shareholders and certain of our employees rights to purchase ordinary shares and warrants to purchase our ordinary shares. The rights offering resulted in net proceeds of approximately $19.7 million. See "Material Agreements — Fab 2 Securities Issuances."

Trend Information

The semiconductor industry has historically been highly cyclical on a seasonal and on a long-term basis. On a long-term basis, the market has fluctuated, cycling through periods of weak demand, production overcapacity, excess inventory and lower sales prices and periods of strong demand, full capacity utilization, product shortages and higher sales prices. Although there can be no assurance that this trend will continue, the semiconductor industry now appears to be in the midst of a cyclical upswing. According to Worldwide Semiconductor Trade Statistic Organization, worldwide sales of semiconductors increased 6.8% to $15.4 billion in October 2003, up from $14.4 billion in September 2003, which represented the eighth consecutive monthly increase. As a result of this recent growth in semiconductor demand, we believe, based on market data information made publicly available by leading Asian foundries, that these foundries are experiencing tight capacity due to rising orders. According to Dataquest, U.S.-based IDMs have increased orders from major foundries for leading edge process technology and to avoid investing in more advanced fabs. Two leading Taiwanese foundries recently reported that they expect to achieve overall utilization rates exceeding 90% in the fourth quarter of 2003. While we experienced a decrease in the revenues of Fab 1 which utilizes older technologies during the third quarter of 2003, we believe that our more advanced Fab 2 is well positioned to benefit from this trend, especially considering that we are one of a few semiconductor manufacturing companies that increased its investments in new capacity during the worst downturn in the history of the semiconductor industry.

There is a trend within the semiconductor industry toward ever-smaller features. State-of-the-art fabs are currently using process geometries of 0.18 microns and below. As demand for smaller geometries

35




increases, there is downward pressure on the pricing of larger geometry products and increasing underutilization of fabs that are limited to manufacturing larger geometry products, which results in less profitability for manufacturers of larger geometry products. Fab 1 is limited to geometries of 0.35 microns and above and Fab 2 currently operates at process geometries of 0.18 microns and produces 200-mm wafers. In order for an independent wafer foundry to successfully compete, it must decrease the process geometries with which it manufactures wafers every 18 to 24 months, and it must purchase or develop suitable technology, which typically costs between $30 million and $50 million per generation. A new generation of process technology will also require the purchase of manufacturing equipment, which currently costs approximately $20 million to provide capacity to produce 1,000 wafer starts per month. In order for us to successfully compete over the long term, we must be capable of manufacturing wafers with increasingly smaller geometries. We have already begun the transfer to us of 0.13 micron process technology which we licensed from Motorola, and our Fab 2 business plan contemplates the purchase of manufacturing equipment necessary to manufacture wafers with a process geometry of 0.13 microns. We plan to initiate volume production in geometries of 0.13 microns at Fab 2 during 2005.

Quantitative and Qualitative Disclosures about Market Risk

Market risk is the risk of loss related to changes in market prices, including interest rates and foreign exchange rates, of financial instruments that may adversely impact our consolidated financial position, results of operations or cash flows.

Our primary market risk exposures relate to interest rate movements on borrowings and fluctuations of the exchange rate of the US dollar, which is the primary currency in which we conduct our operations, against the NIS, the Japanese Yen and the Euro. To manage those risks and mitigate our exposure to them, we from time to time use financial instruments, primarily collar agreements with a knock-out feature, cylinder options (call & put) and forward transactions.

All financial instruments are managed and controlled under a program of risk management in accordance with established policies. These policies are reviewed and approved by our board of directors. Our treasury operations are subject to an internal audit on a regular basis. We do not hold derivative financial instruments for speculative purposes, and we do not issue any derivative financial instruments for trading or speculative purposes.

Risk of Interest Rate Fluctuation

We have market risk exposure to changes in interest rates on our long-term debt obligations with floating interest rates. We primarily enter into debt obligations to support capital expenditures and needs. From time to time, we enter into interest rate collar agreements to modify our exposure to interest rate movements. These agreements limit our exposure to the risk of fluctuating interest rates by allowing us to convert a portion of the interest on our borrowings from a variable rate to a limited variable rate. We entered into interest rate collar agreements that expire in 2007 in the amount of $212 million, of which $172 million is effective as of September 30, 2003. With respect to $172 million of the Fab 2 credit facility debt, under the terms of these collar agreements, if the LIBOR is below the floor rate of 4.28%, we will pay total interest at the fixed rate of 5.83%; if the LIBOR is between 4.28% and 5.56%, we will pay interest at the actual LIBOR plus 1.55%; if the LIBOR is between 5.56% and 7.50%, we will pay total interest at a fixed rate of 7.11%; and if the LIBOR is higher than 7.50%, we will pay the actual LIBOR rate plus 1.55%. At September 30, 2003, the LIBOR rate was 1.19%. Accordingly, as of September 30, 2003, the interest rate on the $172 million of long-term loans covered by the collar agreements was 5.83%, and the interest rate on the $179 million of long-term loans not subject to the collar agreements was 2.74%. These collar agreements resulted in a loss of $4.0 million in the nine months ended September 30, 2003, of which $2.5 million was capitalized to property and equipment. The fair value of the interest rate collar, as of September 30, 2003, was a $12.2 million loss. Assuming a 10% upward shift in the LIBOR rate at September 30, 2003, (from 1.19% to 1.30%), the effective fair value of the $179 million debt that is not hedged by the collar

36




agreements, and as to which we are exposed to the risk of interest rate fluctuation, would have increased by $0.8 million. The $172 million debt hedged by the collar agreements would not have changed assuming such interest rate increases.

As of the date of this prospectus, our facility agreement with our banks was amended as described in "Material Agreements — Credit Facility." This analysis does not reflect the amended terms.

Under the terms of the $40 million collar agreements to be effective as of July 2004 and the credit facility, if the LIBOR is below 2.8%, we will pay total interest at the fixed rate of 4.35%; if the LIBOR is between 2.8% and 5.5%, we will pay interest at the LIBOR plus 1.55%; if the LIBOR is between 5.5% and 7.50%, we will pay total interest at a fixed rate of 7.05%; and if the LIBOR is higher than 7.50%, we will pay the LIBOR rate plus 1.55%.

Our cash equivalents and short-term interest-bearing deposits are exposed to market risk due to fluctuation in interest rates, which may affect our interest income and the fair market value of our investments. We manage this exposure by performing ongoing evaluations of our investments in those deposits. Due to the short maturities of our investments, the carrying value approximates the fair value.

Foreign Exchange Risk

Our main foreign currency exposures give rise to market risk associated with exchange rate movements of the US dollar, our functional and reporting currency, against the Japanese Yen, the Euro and the NIS. To protect against reductions in value and against the volatility of future cash flows caused by changes in foreign exchange rates, we utilize forward transactions and currency cylinder options to minimize part of the impact of foreign currency fluctuations on our financial position and results of operations. Most of those agreements are designated to eliminate exposure changes in the Japanese Yen and the Euro vis-à-vis the US dollar. A cylinder option is a combination of a purchased call option and a written put option. The combination of these options limit our exposure to changes in the exchange rate of the US dollar against foreign currencies by placing a maximum and minimum effective exchange rate, and accordingly, the dollar amount to be paid for equipment purchases. The forward transactions limit our foreign exchange risk exposure by placing a predetermined effective exchange rate. During the nine months ended September 30, 2003, we had options in an aggregate amount of $45 million, which resulted in this period in a $ 2.3 million gain (mostly capitalized to property and equipment). As of September 30, 2003, we had no open transactions.

We are exposed to the risk of fluctuation in the NIS/dollar exchange rate with respect to our convertible debentures and the exercise price of our Options (Series 1), which are both denominated in NIS linked to the Consumer Price Index in Israel, or CPI. As of September 30, 2003, the outstanding principal amount of the convertible debentures was NIS 116.6 million (equivalent to $26.3 million), and the exercise price of the Options (Series 1) was NIS 41.1 (equivalent to $9.30). The dollar amount of our finance costs (interest and currency adjustments) related to the convertible debentures will be increased if the rate of inflation in Israel is not offset (or is offset on a lagging basis) by the devaluation of the NIS in relation to the dollar. In addition, the dollar amount of any repayment on account of the principal of the convertible debentures will be increased as well. On the other hand, if the devaluation of the NIS against the dollar is greater than the rate of inflation in Israel, the dollar amounts we shall raise on the date of exercising our Options (Series 1) will be decreased. From the date of the issuance of the convertible debentures and Options (Series 1) in January 2002 until September 2003, the CPI increased by 5.4% while the US dollar/NIS exchange rate decreased by 3.1%.

Approximately half of the convertible debentures amount is covered by a deposit denominated in NIS and linked to the CPI. Therefore, we are exposed to the risk of fluctuations in the NIS/dollar exchange rate only for the remaining balance of the convertible debentures.

37




The convertible debentures bear annual interest at a fixed rate of 4.7%. The debentures are payable in four annual installments commencing January 2006. Therefore, we are not subject to exposure to interest rate fluctuations with respect to the debentures.

We enter, from time to time, into foreign exchange agreements to hedge exposure relating to Value Added Tax, grants receivables and payroll expenses denominated in NIS. The effect of these agreements during the nine months ended September 30, 2003 was immaterial. As of September 30, 2003, we had no open transactions.

We are exposed to currency risk in the event of default by the other parties of the exchange transaction. The likelihood of such default is remote, as the other parties are widely recognized and reputable Israeli banks.

Impact of Inflation

We believe that the rate of inflation in Israel has had a minor effect on our business to date. However, our dollar costs in Israel will increase if inflation in Israel exceeds the devaluation of the NIS against the dollar or if the timing of such devaluation lags behind inflation in Israel.

Business

Company Overview

We are a pure-play independent wafer foundry dedicated to the manufacture of semiconductors. Pure-play foundries do not offer any products of their own, but focus on producing ICs based on the design specifications of their customers. We manufacture semiconductors using advanced production processes for our customers primarily based on third party designs and our own proprietary designs. We currently manufacture integrated circuits, or ICs, with geometries ranging from 1.0 to 0.18 microns and plan to initiate volume production in geometries of 0.13 microns during 2005. ICs manufactured by us are incorporated into a wide range of products in diverse markets, including consumer electronics, personal computer and office equipment, communications, automotive, professional photography and medical device products.

We are focused on establishing leading market share in high-growth specialized markets by providing our customers with high-value wafer foundry services. Our historical focus has been standard digital complementary metal oxide semiconductor, or CMOS, process technology, which is the most widely used method of producing ICs. We currently are focused on the emerging opportunities surrounding CMOS image sensors, embedded flash and mixed-signal technologies. Through our expertise and experience gained over a decade of operations, we differentiate ourselves in these areas by creating a high level of value for our clients through innovative technological processes, competitive manufacturing indices, such as cycle times and yields, and dedicated customer service.

Our Company was founded in 1993, when we acquired National Semiconductor's 150-mm wafer fabrication facility, or Fab 1, and commenced operations as an independent foundry with a production capacity of approximately 5,000 wafer starts per month. Since then, we have significantly modernized our facilities and equipment, which has improved our process geometries from 1.0 microns to 0.35 microns and enhanced our process technologies to include CMOS image sensors, embedded flash and mixed-signal technologies. We have also expanded our capacity through increased production in Fab 1 to approximately 16,000 wafer starts per month to meet additional customer demand. Fab 1 has been cash flow positive for the past six quarters.

We have recently completed the construction of the building and infrastructure and commenced the initial ramp-up of a second manufacturing facility, or Fab 2. Fab 2 is designed to operate in geometries of 0.18 microns and below, using advanced materials and advanced CMOS technology licensed from Motorola and Toshiba and other technologies that we might acquire or develop independently. Production capacity at the end of December 2003 was 8,500 wafer starts per month. We currently expect to have production capacity ranging between 13,000 and 15,000 wafer starts per month by the end of 2004. When the production ramp-up is completed, Fab 2 is expected to have a capacity of 33,000 200-mm wafer starts per month. While we expect to continue to operate Fab 1, we anticipate Fab 2 to be the core of our future business.

Industry Overview

Semiconductor devices are responsible for the rapid growth of the electronics industry over the past fifty years. They are critical components in a variety of applications, from computers, consumer electronics and communications, to industrial, military, medical and automotive. The semiconductor industry is characterized by rapid changes in technology, frequently resulting in the obsolescence of recently introduced products. As performance has increased and size and cost have decreased, the use of semiconductors and the number of their applications have grown significantly.

Historically, the semiconductor industry was composed primarily of companies that designed and manufactured ICs in their own fabrication facilities. These companies, such as Intel and IBM, are known as integrated device manufacturers, or IDMs. In the mid-1980s, fabless IC companies, which focused on IC design and used external manufacturing capacity, began to emerge. Fabless companies initially outsourced production to IDMs, which filled this need through their excess capacity. As the

39




semiconductor industry continued to grow, increasing competition forced fabless companies and IDMs to seek reliable and dedicated sources of IC manufacturing services. This need has been met by the development of independent companies, known as foundries, that focus primarily on providing IC manufacturing services to semiconductor suppliers. Foundry services are now used by nearly every major semiconductor company in the world, including IDMs as part of a dual-source, risk-diversification strategy.

Semiconductor suppliers face increasing demands for new products that provide higher performance, greater functionality and smaller form factors at lower prices, which require increasingly complex ICs. To compete successfully, semiconductor suppliers must also minimize the time it takes to bring a product to market. As a result, fabless companies and IDMs are focusing more on their core competencies — design and intellectual property — and outsourcing manufacturing to foundries. In addition to the increased complexity of designs, there has also been a dramatic increase in the number of applications for semiconductors, driving significant growth in the semiconductor market.

With increased demand for these new applications, particularly in the consumer sector, the semiconductor industry is now recovering from its worst downturn in history. According to the Worldwide Semiconductor Trade Statistic Organization, worldwide sales of semiconductors increased 6.8% to $15.4 billion in October 2003, up from $14.4 billion in September 2003, which represented the eighth consecutive monthly increase. IC Insights, a market research firm, projects that the worldwide semiconductor market will grow from approximately $141 billion in 2002 to approximately $225 billion in 2007, representing a five-year compound annual growth rate of 10%.

As a result of this recent growth in semiconductor demand, two leading Taiwanese foundries, which according to IC Insights account for over 70% of worldwide sales of ICs, have reported that they are experiencing tight capacity due to rising orders. These Taiwanese foundries have also reported that U.S.-based IDMs have increased their orders because their own capacities could not handle emergent orders from clients. According to IC Insights, these foundries recently reported that they both expect to achieve overall utilization rates exceeding 90% in the fourth quarter of 2003. With Fab 2 beginning commercial production in the third quarter of 2003, we believe that, like these foundries, we are well-positioned to benefit from this trend especially considering that we are one of a few semiconductor manufacturing companies that increased its investments in new capacity during the worst downturn in the history of the semiconductor industry.

The consumer sector, which currently represents 17% of semiconductor demand, is expanding worldwide with new applications and multi-functional devices, including those that incorporate CMOS image sensors, embedded flash and mixed-signal ICs. Increasingly, emerging applications, such as camera-equipped cell phones, digital still cameras and flat panel displays, are enabled by ICs manufactured using advanced process technologies.

As the semiconductor industry continues its expansion, the cost of building new fabrication facilities, or fabs, is becoming increasingly prohibitive for all but a very few companies. For example, the total cost of our Fab 2 is currently expected to be approximately $1.5 billion. We believe that new 300-mm wafer fabs cost approximately twice that amount. For companies to justify the enormous investment in a new fab, a high level of capacity utilization is essential to ensure that fixed costs are fully absorbed. Because independent foundries serve a large customer base they are generally well-positioned to enjoy higher utilization rates than IDMs.

The enormous costs associated with modern fabs, combined with the increasing demand for complex ICs, has created an expanding market for outsourced manufacturing offered by foundries. Foundries can cost-effectively supply the technologies involved in manufacturing advanced ICs to even the smallest fabless companies by creating economies of scale through pooling the demand of numerous customers. In addition, customers whose IC designs require process technologies other than standard digital CMOS have created a market for independent foundries that focus on providing specialized process technologies, such as CMOS image sensors, embedded flash and mixed-signal technologies. Foundries also offer competitive customer service through design, testing, and information services, often at a level previously found only at an IDM's internal facilities.

40




These trends have led to the rapid growth in demand in recent years for advanced semiconductor manufacturing services provided by independent foundries. According to IC Insights, the worldwide pure-play foundry market, which excludes IDMs, was $8.6 billion in 2002 and is projected to grow to $23.6 billion in 2007, representing a five-year compound annual growth rate of 24% — more than double the expected growth rate of the overall semiconductor market for the same period.

The Tower Focus

We provide wafer fabrication services and technologies to fabless IC companies and IDMs and enable smooth integration of the semiconductor design and manufacturing processes. By doing so, we enable our customers to bring high-performance, highly integrated ICs to market rapidly and cost effectively. We believe that our technological strengths and emphasis on customer service have allowed us to develop strong positions in large, high-growth specialized markets for CMOS image sensors, embedded flash memory and mixed signal ICs. We serve as a sole source or alternative provider of foundry services.

We believe that we are a trusted, customer-oriented service provider that has built a solid reputation in the foundry industry over the last ten years. We have built strong relationships with customers, who continue to use our services, even as their demands evolve to smaller form factors and new applications. Our consistent focus on providing high-quality, value added services, including engineering and design support, has allowed us to attract customers for both our Fab 1 and Fab 2 facilities who seek to work with a proven provider of foundry services. As a result, we have a high customer retention rate, which is illustrated by our long-standing relationships with leading semiconductor suppliers such as Motorola and National Semiconductor.

Strong relationships in the industry have been an important facet of our success and will continue to be important in the future. In order to enhance these relationships, we have created relationships with partners that have made significant investments in Fab 2 to enhance mutual growth plans. These investments were made during the recent industry downturn, when most foundries were reducing capital expenditures. As a result, we believe that we are well-positioned to attract new customers and increase utilization rates as the industry recovers. In addition, our wafer partners were issued wafer credits as part of their investment in Fab 2, which provides them an incentive to outsource manufacturing of their ICs to us (see "Certain Transactions — Wafer Partner Agreements"). We plan to use Fab 2 as a source for volume production of next generation geometries. This plant allows us to meet the evolving needs of our current customers and provide the potential for significant new relationships as semiconductor suppliers seek to meet their outsourcing needs.

We serve as a sole-source provider for most of our CMOS image sensor and embedded flash customers and also serve as an alternative, second-source provider of other foundry services. Foundry diversification is an increasingly important factor among semiconductor companies, which benefits us due to our unique location. Semiconductor companies have sought to hedge their manufacturing risk by securing production relationships with companies in different parts of the world. Our unique location in Israel, with its close proximity to Europe and its strong semiconductor R&D resources, evident through the presence of multinational corporations, such as Broadcom, Intel, Marvell, Motorola, National Semiconductor, SanDisk, Texas Instruments, and Zoran and numerous fabless IC companies, strengthens our competitive position as a second-source provider of foundry services. In addition, as foundry utilization rates peak, we expect to attract additional customers with our standard 0.18-micron process technology and future 0.13-micron process technology.

Our Target Markets

We derived approximately 60% of our revenues for the nine-month period ended September 30, 2003 from our target specialized markets: CMOS image sensors, embedded flash and mixed-signal ICs. We are focusing on these markets because they provide a relatively high gross margin and have high growth characteristics. In addition, we are highly experienced in these markets, being an early entrant and having developed unique proprietary technologies, primarily through licensing and joint development efforts with our customers and other technology companies.

CMOS Image Sensors

CMOS image sensors are ICs used to capture an image in a wide variety of consumer, commercial and industrial mass market applications, including camera-equipped cell phones, digital still and video cameras, security and surveillance cameras and video game consoles. We are currently actively involved in this mass market as well as the high-end sensor and applications specific markets, which includes applications such as studio quality megapixel digital cameras, ingestible capsule cameras for medical imaging and rearview mirrors that automatically dim to eliminate glare. While CMOS image sensors for advanced optical applications are an emerging technology, we believe that they are gradually becoming the preferred technology to traditional charge coupled devices, or CCDs. CCDs have historically provided superior image quality; however, advances in semiconductor manufacturing processes and design techniques have led to significant improvements in CMOS image sensor performance and image quality. These advances have resulted in smaller size circuits and better current control, making it possible to design CMOS image sensors that provide high image quality at a significantly lower cost.

As early as 1997, we recognized the market potential of using CMOS process technology for a digital camera-on-a-chip, which would integrate a CMOS image sensor, filters and digital circuitry. In entering the CMOS image sensor foundry business, we utilized research and development work that had been ongoing since 1993. Our services include a broad range of turnkey solutions and services, including sensor design services, optical characterization of a CMOS process, innovative stitching manufacturing technique and optical testing and packaging. CMOS image sensors manufactured by us deliver outstanding image quality for a broad spectrum of digital imaging applications. Currently, we are one of few foundries that manufacture CMOS image sensors and, as such, believe that we have developed leading market position.

According to In-Stat/MDR, a market research firm, the CMOS image sensor market is expected to grow from $184 million in 2002 to $547 million in 2007, representing a five-year compound annual growth rate of 24%. In-Stat/MDR also forecasts that CMOS image sensors will grow from approximately 30 million units in 2002 to 221 million units in 2007, representing a five-year compound annual growth rate of 49%. Two of the markets expected to provide much of the growth for CMOS image sensors are camera-equipped cell phones and digital still cameras.

Embedded Flash

Flash memory is a constantly powered nonvolatile memory that can be erased and reprogrammed in units of memory called blocks. The IC of flash memory is organized so that a section of memory cells may be erased in a single action (or "flash"). Applications for flash memory products range from most types of portable electronic equipment devices to high volume mass storage of data. Flash is particularly suitable for applications such as handheld devices, combining the need for portability, high density, ruggedness and lower power requirements. Flash memory products are also well-suited for audio products such as digital answering machines and MP3 players, as well as other applications including networking devices, digital cameras, personal computer motherboards and portable memory devices.

Embedded flash is the combination of flash memory with other components, such as other memory, logic and analog, on a single IC to provide speed, functionality and form factor advantages and reduce system cost. Embedded flash memory products are used in communications, consumer, industrial, military and automotive applications. End products include networks, base stations, servers, microcontrollers, toys, set-top boxes, DVD players, cell phones and smart cards.

In 1997 we entered into a strategic investment and technology agreement with Saifun, pursuant to which we currently own approximately a 10% equity stake in Saifun. Together we brought to market a new non-volatile memory technology, NROM™. NROM technology enables the implementation of ultra high-density flash arrays using 0.5-micron CMOS process, and is particularly suitable for

42




embedding flash arrays with standard CMOS logic, as well as for commodity memories. We have continued to strengthen our specialized technology service offering and leadership position in the embedded flash market, most recently by partnering with Matsushita for joint development of 0.18-micron embedded microFLASH technology. Our microFLASH technology, based on Saifun's patented NROM technology, provides greater memory cell density than other currently available flash architectures for given design rule generation, permitting an approximately four-fold reduction in the size of the memory cell for stand-alone memories and embedded applications in a given geometry.

IC Insights forecasts an increase in the worldwide flash memory market from $7.8 billion in 2002 to $20.0 billion by 2007, representing a five-year compound annual growth rate of 21%. According to Semico Research, a market research firm, embedded flash in microcontrollers is expected to grow from $4.0 billion in 2002 to $17.0 billion in 2007, representing a five-year compounded annual growth rate of 34%.

Mixed Signal

Mixed-signal ICs are an essential part of any electronic system that interacts with the real world. Analog ICs monitor and manipulate real world signals such as sound, light, pressure, motion, temperature and electrical current and are used in a wide variety of electronic products such as PCs, cell phones, DVD players, automotive electronics and medical imaging equipment. Digital ICs perform arithmetic functions on data represented by a series of ones and zeroes, provide critical processing power and have enabled many of the computing and communication advances of recent years. Mixed-signal ICs combine analog and digital semiconductor functionality on a single IC to enable digital systems to interface with the real world. As these digital systems proliferate, there is a growing need for analog functionality to enable them to interface with the real world.

We focus on providing high-quality mixed-signal capabilities, as this technology is a cornerstone to both CMOS image sensor and embedded flash applications. Our expertise in mixed signal has been further enhanced through several strategic initiatives. In 1998, Motorola transferred its 0.6- and 0.8-micron analog and mixed-signal processes to our Fab 1 facility. Additionally, in 2002 we signed an agreement with Interuniversity MicroElectronics Center, or IMEC, for the technology transfer and licensing of analog modules and applicable technologies for our Fab 2. In May 2003, we licensed a wide array of intellectual property from Chipidea, whereby Chipidea will port its IP to our Fab 2. Our customers can now use Chipidea's extensive IP portfolio with our advanced technology for a state-of-the-art solution that meets their analog and mixed-signal design needs. The solutions available under our license agreements with IMEC and Chipidea are available to us from additional technology suppliers; we therefore may choose to renew our present licenses or to obtain additional technology licenses in the future.

According to Dataquest, a market research firm, the worldwide general-purpose analog and mixed-signal IC market was $9.3 billion in 2002 and is projected to grow to $17.6 billion in 2007, representing a five-year compound annual growth rate of 14%.

Our Strategy

We focus on establishing leading market position in specialized markets by providing our customers with high-value wafer foundry services. We believe that our success and profitability depend on the success of our customers. Therefore, to maintain and enhance our position as a specialized technology market leader, we pursue a business strategy with a focus on a partnership business model, designed to accommodate our customers' business objectives and needs and to promote their interests as our partners. The key elements of our strategy are:

Establishing Leading Market Share for Specialized, High Growth Applications.    We focus on the emerging opportunities surrounding CMOS image sensors, embedded flash and mixed-signal ICs. In addition to their high gross margins, we are focusing on these markets because of their large size and

43




high growth characteristics. With our advanced manufacturing technologies and service capabilities, we have established a strong position in these markets with industry leaders, including Kodak, Matsushita, Motorola, National Semiconductor, SanDisk and Zoran.

Pursuing a Partnership Business Model.    We believe that the use of our customers as an equity financing source, such as in the case of Alliance Semiconductor, Macronix, SanDisk and QuickLogic (to which we refer as our "wafer partners"), will strengthen our long-term relationships with these parties, as our growth objectives are closely aligned. We granted our existing wafer partners a right to purchase up to approximately 50% of the capacity of our Fab 2 facility, and we believe that their ownership interest in us provides them added incentive to utilize this capacity.

Maintaining Our Commitment to Customer Service.    We place significant emphasis on providing world-class customer service, research and development, as well as engineering support and execution of complex process and product transfers, while maintaining reduced cycle times and higher product yields. We believe that our customer service has helped us differentiate ourselves from our larger competitors, as demonstrated by Motorola naming us "Foundry of the Year" in 1999 and awarding us "Gold Supplier" status in 2000, 2001 and 2002. As a result, we have a high customer retention rate, which is illustrated by our long-standing relationships with leading semiconductor suppliers such as Fairchild Semiconductor, Motorola and National Semiconductor. We also serve as the sole-source provider for certain customers' products, such as QuickLogic, which we believe rely on us for the manufacture of all of their ICs due to our commitment to develop technologies specific to their needs.

Expanding Our Technological Expertise through Licensing and Joint Development Efforts with Leading Technology Companies.    In addition to our independent research and development resources, we seek to partner with technology companies to expand our core strengths in CMOS image sensors, embedded flash and mixed-signal technologies by combining our proprietary technology with that of leading technology companies. In the past, this arrangement has been highly successful. Our high-quality CMOS image sensor technology was used to optimize Kodak's complex image-sensor design for volume production, and this project has, in turn, enhanced our CMOS image sensor technology. A significant number of our embedded flash solutions, which offer significant form factor and cost advantages relative to the competition, were developed through our relationships with Matsushita and Saifun. In addition, our mixed-signal offering for 0.18-micron CMOS processes has been improved through the use of proprietary technology from Toshiba, and our analog capabilities have been improved through a technology transfer and licensing arrangement with IMEC. These relationships have been an important part of creating a competitive advantage in these applications, and we are continuing to pursue similar relationships in the future. For example, to enhance our capabilities at Fab 2, we entered into technology transfer agreements with Motorola and Toshiba that will enable us to provide advanced 0.18- and 0.13-micron CMOS technologies. These relationships also allow us to minimize R&D expenses for developing new technologies.

Enhancing Our Global Sales and Marketing Efforts.    We focus our sales and marketing efforts on technology and service driven leading customers, with sophisticated products in industries with high gross margins and growth potential. Over the past year, we have significantly increased our global sales and marketing efforts in order to establish worldwide coverage to support the ramp-up of our Fab 2 facility. As part of this effort, we have sales personnel located in the United States, Israel and Japan, as well as a worldwide network of independent sales representatives. We believe that this presence will allow us to address significant market opportunities worldwide.

Maximizing Capacity Utilization.     We seek to maximize capacity utilization by attracting new customers and rapidly expanding our capabilities for high-margin advanced technologies through the construction of Fab 2. Over the course of our history, our business model has involved targeting capacity growth in standard digital CMOS technology and then migrating that capacity to specialized, high-end technologies. Fab 1 provides a steady source of funds, as it generates cash at even modest production levels. In order to optimize production levels of Fab 1, we seek to operate the facility at close to maximum capacity with the most advanced technologies it can produce. Fab 2 is the core

44




focus of our future efforts, and we are ramping up production in the facility to meet customer demand. Fab 2 seeks to maximize returns by addressing the market for more advanced geometries, which have relatively higher gross margins. In order to consistently meet this demand, we have plans for both capacity expansion at the current 0.18-micron geometry and volume production at 0.13-micron geometry by 2005.

Becoming a Preferred Second-Source Foundry Service Provider.    We serve as a sole-source provider for many of our customers for certain of their products and devices, and we also offer our services as an alternative or second-source provider of foundry services. Foundry diversification is an increasingly important factor among semiconductor companies, including both IDMs and fabless IC companies. In previous industry cycles when semiconductor demand was high, there was a shortage of IC manufacturing capacity. Because the semiconductor industry is now recovering from its worst downturn in history, we aim to take advantage of an expected capacity shortage during this upswing by becoming a preferred second-source provider of IC manufacturing services. In particular, as foundry utilization rates peak and available capacity decreases at leading Asian foundries, we expect to attract new customers with our standard 0.18-micron process technology and future 0.13-micron process technology.

Customers, Marketing and Sales

Our marketing and sales strategy seeks to aggressively expand our global customer base to take advantage of the current upswing in the semiconductor industry. To achieve this objective, we match our standard digital CMOS technology to the industry benchmark and differentiate ourselves based on customer service, design support and expertise in specialized technologies, such as CMOS image sensors, embedded flash and mixed signal. We have marketing and sales personnel in the United States, Japan and Israel. The group in Israel is responsible for covering Israel, Europe and Taiwan. Our marketing and sales staff is supported by independent sales representatives, located throughout the world, who have been selected based on their understanding of the semiconductor marketplace.

Our sales cycle is generally 18-24 months for new customers and can be as short as 9-12 months for existing customers. The typical stages in the sales process from initial contact until production are:

technical evaluation;
product design to our specifications including integration of third party intellectual property;
photomask design specification;
silicon prototyping;
assembly and test;
validation and qualification; and
production.

The primary customers of our foundry services are fabless semiconductor companies and IDMs. A significant portion of our product sales are made pursuant to long-term contracts with our customers, under which we have agreed to reserve manufacturing capacity at our production facilities for such customers. When we commenced business in March 1993, our only customer was National Semiconductor. Since then, we have succeeded in adding a significant number of new customers, including many industry leaders and a number of Taiwanese companies who preferred our solution to that offered locally. During the nine months ended September 30, 2003, our primary customers were:

45





Alliance Semiconductor Macronix QuickLogic
Comtech AHA Micron SanDisk
Cypress Semiconductor Motorola STMicroelectronics
FillFactory National Semiconductor Xemics
Kodak ON Semiconductor  
     

During the nine months ended September 30, 2003, National Semiconductor, Motorola, FillFactory and SanDisk contributed 26%, 15%, 12% and 11% of our revenues, respectively. In 2002, National Semiconductor, Matsushita and Motorola contributed 31%, 16% and 13% of our revenues, respectively. In 2001, National Semiconductor and Motorola contributed 30% and 17% of our revenues, respectively. In 2004, we expect that SanDisk, our number one customer in Fab 2, will account for a significant portion of our Fab 2 revenues. In the third quarter of 2003, SanDisk was instrumental in ramping up our business and accounted for approximately 80% of our Fab 2 revenues. While we currently expect that SanDisk will continue to be a significant customer of Fab 2, the percentage of Fab 2 revenues represented by sales to SanDisk is expected to decrease as additional customers commence or increase their purchase orders following the qualification of their products in Fab 2. As foundry utilization rates peak with the industry recovery, we expect to attract additional customers as available capacity decreases at leading Asian foundries.

In addition to further developing our customer base, we have also made a concentrated effort to expand the geographical diversity of our sales. The percentage of our sales from customers located outside the United States was 10%, 31%, 38% and 28% in the years ended December 31, 2000, 2001 and 2002 and the nine months ended September 30, 2003, respectively. As we have successfully expanded our customer base with customers located in Asia-Pacific and in Europe, we believe that a substantial portion of our sales will continue to come from customers located outside the United States. We experienced a significant increase in our Asia-Pacific sales in 2002 due to payments made to us by Matsushita in connection with our technology agreement with them. The following table sets forth the geographical distribution, by percentage, of our net sales for the periods indicated:


  Nine Months Ended
September 30, 2003
Year Ended December 31,

Israel   1     2     3      
Total   100   100   100   100

We currently allocate a portion of our wafer manufacturing capacity in Fab 2 to certain customers under several types of agreements. We are also obligated to make capacity available to customers under certain other agreements (See "Certain Transactions — Wafer Partner Agreements"). Some of our primary customers are also our shareholders.

Competition

The global semiconductor foundry industry is highly competitive. We compete with approximately 10 independent dedicated foundries, including Taiwan Semiconductor Manufacturing Corporation, United Microelectronics and Chartered Semiconductor Manufacturing; emerging and existing Chinese, Korean, Malaysian and Taiwanese foundries, including Semiconductor Manufacturing International Corp., DongBu, Anam, Hynix, Powerchip Semiconductor and Silterra; other specialized foundries, such as AMI Semiconductor, Jazz Semiconductor and X-Fab; and over 20 IDMs and end-product manufacturers that produce ICs for their own use and/or allocate a portion of their

46




manufacturing capacity to foundry operations. The foundries with which we compete are located in Asia Pacific and benefit from their close proximity to other companies involved in the design and manufacture of ICs.

We believe that the principal elements of competition in the wafer foundry market are:

technical competence;
production quality;
time-to-market;
device and end-product price;
available capacity;
device yields;
design and customer support services;
access to intellectual property; and
research and development capabilities.

Many of our competitors have greater manufacturing capacity, multiple manufacturing facilities, more advanced technological capabilities, a more diverse and established customer base, greater financial, marketing, distribution and other resources and a better cost structure than ours.

We seek to compete primarily on the basis of technology, production quality, device yields and service. We believe we have a differentiated service offering in specialized markets, which enables us to effectively compete with larger IC manufacturers.

Wafer Fabrication Services

Wafer fabrication is an intricate process that consists of constructing layers of conducting and insulating materials on raw wafers in intricate patterns that give the IC its function. IC manufacturing requires hundreds of interrelated steps performed on different types of equipment, and each step must be completed with extreme accuracy for finished ICs to work properly. The process can be summarized as follows:

Circuit Design.    IC production begins when a fabless IC company or IDM designs the layout of a device's components and designates the interconnections between each component. The result is a pattern of components and connections that defines the function of the IC. In highly complex circuits, there may be more than 35 layers of electronic patterns. After the IC design is complete, we provide these companies with IC manufacturing services.

Mask Making.    The design for each layer of a semiconductor wafer is imprinted on a photographic negative, called a reticle or mask. The mask is the blueprint for each specific layer of the semiconductor wafer.

IC Manufacturing.    Transistors and other circuit elements comprising an IC are formed by repeating a series of processes in which a photosensitive material is deposited on the wafer and exposed to light through a mask. Advanced IC manufacturing processes consist of hundreds of steps, including photolithography, oxidation, etching and stripping of different layers and materials, ion implantation, deposition of thin film layers, chemical mechanical polishing and thermal processing. The final step in the IC manufacturing process is wafer probe, which involves visually and electronically inspecting each individual IC in order to identify those that are operable for assembly.

Assembly and Test.    After IC manufacture, the wafers are transferred to assembly and test facilities. In the assembly process, each wafer is cut into dies, or individual semiconductors, and tested. Defective dies are discarded, while good dies are packaged and assembled. Assembly protects the IC,

47




facilitates its integration into electronic systems and enables the dissipation of heat. Following assembly, the functionality, voltage, current and timing of each IC is tested. After testing, the completed IC is shipped to the IC supplier or directly to its final destination.

Manufacturing Processes

We manufacture ICs on silicon wafers, generally using the customer's proprietary circuit designs. In some cases we use third-party designs or our own proprietary product design. The end product of our manufacturing process is a silicon wafer containing multiple identical ICs. In most cases, our customer assumes responsibility for dicing and assembly. Although we are an independent foundry specializing in wafer fabrication, we offer our customers the option to purchase from us finished semiconductor products that have been assembled and tested. In these cases, we take responsibility for the production and delivery of finished IC products to our customer on a turnkey basis and subcontract some or all of the dicing, assembly and testing functions to third parties. We also maintain limited assembly capabilities for manufacturing prototype units to facilitate customer evaluation and thereby accelerate new product introduction.

We manufacture ICs using CMOS process technology. CMOS is currently the dominant semiconductor manufacturing process because it requires lower power than other technologies and allows dense placement of components onto a single IC. The low power consumption and high-density characteristics of the CMOS process allow the continued development of high performance ICs that are smaller and faster. We believe that our specialized process technology distinguishes our IC manufacturing services and attracts many industry-leading customers. The specific process technologies that we focus on include:

CMOS Image Sensors.    Our advanced CMOS image sensor process is intended to meet the established growing demand for optical sensors used in consumer, industrial, medical and automotive applications. Our dedicated manufacturing and testing processes assure consistently high electro-optical performance of the integrated sensor through wafer-level characterization. Our CMOS image sensor process has demonstrated superior optical characteristics, excellent spectral response and high resolution and sensitivity. The ultra-low dark current, high efficiency and accurate spectral response to our photodiode enable faithful color reproduction and acute detail definition.

In addition, our innovative "stitching" technology enables semiconductor exposure tools to manufacture single ultra high-resolution CMOS image sensors containing millions of pixels at sizes far larger than their existing field. Our 0.5-and 0.35-micron CMOS image sensor processes permit the customer to create high-quality solutions and integrate a product's CMOS analog and logic circuitry together with the sensor pixel array all on one chip, thereby facilitating miniaturization, reducing power consumption and increasing performance. We are currently developing a 0.18-micron CMOS image sensor process to address the rapidly growing market for camera-embedded cell phones and low end digital cameras.

Embedded Flash.    Our microFLASH technology, based on Saifun's patented NROM technology, provides greater memory cell density than other currently available flash architectures for given design rule generation, permitting an approximately four-fold reduction in the size of the memory cell for stand-alone memories and embedded applications in a given geometry. The relative simplicity of our microFLASH manufacturing process enables the technology to offer cost advantages over competing flash technologies for high density memories. Using our 0.5-micron technology, we have introduced the first of our microFLASH processes into production with the manufacture of a 2 megabit stand-alone memory device and embedded multi-time programming modules, with a limited number of rewrite cycles.

Mixed Signal.    We have developed the Tower Mixed-Signal Design Kit, which contains a comprehensive characterization of a wide range of analog devices, providing our customers with the ability to design mixed-signal ICs for their specific needs. In addition, we developed certain mixed-signal features for use with our 0.18-micron process and are working to develop more features.

Manufacturing Facilities

Fab 1

We acquired our Fab 1 facility from National Semiconductor in March 1993 when National Semiconductor, which had operated the facility since 1986, sold the facility as part of a worldwide restructuring of its manufacturing operations. We occupy the facility pursuant to a long-term lease from the Israel Lands Authority that expires in 2032.

Due to the sensitivity and complexity of the semiconductor manufacturing process, a semiconductor manufacturing facility requires a special "clean room" in which most of the manufacturing functions are performed. Our Fab 1 facility includes an approximately 51,900 square foot clean room.

Since we commenced manufacturing at Fab 1, we have increased our manufacturing capacity from 5,000 wafer starts per month, using 1.25-micron and 1.0-micron processes, to approximately 16,000 wafer starts per month based on our current product mix, which is primarily concentrated on our 0.35-micron, 0.5-micron and other specialized processes. However, our exact capacity is variable and depends on the combination of the processes being used and may be significantly lower at certain times as a result of certain of our combinations. In general, our ability to increase our manufacturing capacity has been achieved through the addition of equipment, improvement in equipment utilization, the reconfiguration and expansion of the existing clean room area and the construction of an additional clean room area within the building shell of Fab 1. Approximately 60% of our Fab 1 facility is capable of 0.5-micron and below process technology.

Fab 2

In January 2001, we commenced construction of Fab 2, our new advanced wafer fab adjacent to Fab 1 in Migdal Haemek. Fab 2 offers IC manufacturing services utilizing advanced materials and a 0.18-micron process technology we licensed from Toshiba. We have also licensed 0.13-micron process technology from Motorola, which we are developing and expect to offer in the future. The overall clean room area in Fab 2 is approximately 100,000 square feet. We began volume production at Fab 2 during the third quarter of 2003. Production capacity at the end of December 2003 was 8,500 wafer starts per month, and we currently expect to have production capacity ranging between 13,000 and 15,000 wafer starts per month by the end of 2004. We expect the production ramp to be completed by the end of 2006, at which time Fab 2 is expected to have the capacity to produce 33,000 wafer starts per month. We currently expect that the total cost of the construction, equipping of the facility and ramp-up of the manufacturing line will be approximately $1.5 billion, of which approximately $824 million has been expended through September 30, 2003. The land on which Fab 2 is located is subject to a long-term lease from the Israel Lands Authority that expires in 2049.

Since 2000, we have invested significantly in the purchase of fixed assets, primarily in connection with the construction of Fab 2, technology advancement and capacity expansion. For the nine-month period ended September 30, 2003, capital expenditures for the purchase of plant and equipment were approximately $135 million before related Investment Center grants of $24 million. Capital expenditures in fiscal 2002, 2001 and 2000 were approximately $209 million, $336 million and $64 million, before related Investment Center grants of $37 million, $67 million and $21 million, respectively.

Procurement and Sourcing

Our manufacturing processes use many raw materials, including silicon wafers, chemicals, gases and various metals. These raw materials generally are available from several suppliers. In many instances, we purchase raw materials from a single source. In connection with our technology advancement plans, including our Fab 2 business plan, we expect to continue to make purchases of semiconductor manufacturing equipment.

Research and Development

Our future success, depends to a large degree, on our ability to continue to successfully develop and introduce to production, advanced process technologies that meet our customers' needs. Our process development strategy relies on process technologies that we primarily license from third parties (See "— Material Licensing Arrangements"); develop at our customers' request or in cooperation with our customers; and internally develop utilizing intellectual property licensed from third parties.

The completion of the construction of Fab 2 and qualification of advanced CMOS process technologies in geometries of 0.18 microns have enabled us to focus on development of process technologies in the specialized CMOS image sensor, embedded flash and mixed-signal markets. Our technology alliances with leading semiconductor suppliers contribute to our development of new process technologies in Fab 2. For example, our joint development alliance with Matsushita in May 2002 has accelerated the development of our 0.18-micron microFLASH technology, which is expected to begin prototyping in the middle of 2004 and be offered in Fab 2 in 2005. In addition, our technology transfer and licensing agreement entered into in January 2002 with IMEC enables us to offer certain advanced analog and mixed-signal technologies for use in Fab 2 in geometries of 0.18 microns for the manufacture of components used in products such as cell phones.

From time to time, at a customer's request, we develop a specialty process module, which we use for such customer on an exclusive basis, and, if permitted under our agreements with our customers, we then add it to our process offering. In 2001 and 2002, in cooperation with a customer, and using its know-how and IP, we developed an enhanced 0.35-micron CMOS image sensor process to be used exclusively for this customer. Production ramp on this process is currently expected to start by the end of 2003.

Our research and development activities have related primarily to our process development efforts and have been sponsored and funded by us with some participation by the Israeli Office of the Chief Scientist, or OCS. Accordingly, we are subject to restrictions set forth in Israeli law which limit the ability of a company to manufacture products, or to transfer technologies outside of Israel, if such products or technologies were developed with OCS funding. Research and development expenses for the years ended December 31, 2000, 2001, 2002 and the nine months ended September 30, 2003 were $9.0 million, $9.6 million, $17.0 million and $12.6 million, net of government participation of $0.9 million, $1.3 million, $1.4 million and $0.9 million, respectively. In addition, we have paid a total of $37.0 million to Toshiba and Motorola in connection with the transfer of process technologies for use in Fab 2.

As of September 30, 2003, we employed 160 professionals in our research and development department, 27 of whom have PhDs. In addition to our research and development department, located at our facilities in Migdal Haemek, we maintain a design center in Netanya, Israel.

Intellectual Property and Licensing Agreements

Our success depends in part on our ability to obtain patents, licenses and other intellectual property rights covering our production processes. To that end, we have acquired certain patents and patent licenses and intend to continue to seek patents on our production processes. As of December 29, 2003, we held 48 patents.

We have also entered into various patent licenses and cross-licenses with other technology companies including Toshiba, Motorola, Synopsys, Artisan Components, ARM, Ceva, IMEC, Cadence Design Systems, Chipidea Microelectronics, Matsushita and Virage Logic. We may choose to renew our present licenses or to obtain additional technology licenses in the future. There can be no assurance that any such licenses could be obtained on commercially reasonable terms. In addition, we cannot assure you that other countries in which we market our services will protect our intellectual property rights to the same extent as the United States or Israel.

We constantly seek to strengthen our technological expertise through relationships with technology companies and silicon suppliers. We seek to expand our core strengths in CMOS image sensors,

50




embedded flash and mixed-signal technologies by combining our proprietary technology with those of other technology companies. A main component of our process development strategy is to acquire licenses to standard CMOS technologies and cell libraries from leading designers, such as Motorola and Toshiba, and further develop specialized process through our internal design teams. The licensing of these technologies has enormously reduced our internal development costs.

CMOS Process Technology Platform

We have licensed an array of process technologies through the following arrangements:

Toshiba.    In April 2000, we entered into a technology transfer agreement with Toshiba, pursuant to which Toshiba has and will transfer to us certain advanced CMOS technologies for use in Fab 2. In exchange for certain license and technology transfer fees and royalties, Toshiba has and will provide us with recipes, know-how and patent licenses and has trained a group of our engineers and managers. Subject to prior termination for cause by Toshiba, our licenses under the agreement with Toshiba are perpetual. Based on Toshiba's 0.18-micron CMOS process technology, we have internally developed an enhanced industry compatible version of the process technology.
Motorola.    In September 2002, we entered into a technology transfer and development agreement with Motorola, pursuant to which Motorola has and will transfer to us its 0.13-micron HiPerMOS7 CMOS process technology for Fab 2 as well as co-develop with us an industry-standard compatible version of the process technology. Subject to prior termination for cause by Motorola, our licenses under the technology transfer agreement with Motorola are perpetual.

Foundation IP (Libraries)

To better serve our customers design needs in advanced CMOS processes, we have entered into a series of agreements with leading providers of physical design libraries. These libraries are basic design building blocks, such as standard cells, interface input-output (I/O) cells and software compilers for the generation of on-chip embedded memories arrays. To achieve optimal performance, these libraries must be customized to work with our manufacturing process and are used in virtually every digital chip design of our customers.

Synopsys.    In June 2001, we entered into an agreement with Synopsys (formerly, Avant!) under which Synopsys has developed libraries for our 0.18-micron process technology. The Synopsys libraries are available to our customers free of charge, and multiple customers use them in producing their ICs at Tower.
Artisan Components.    In June 2002, we entered into a master services and license agreement with Artisan Components. Under this agreement, Artisan Components has developed a suite of library products for our 0.18-micron process technology. Artisan Components is licensing its libraries to our customers free of charge and multiple customers are using the Artisan Components libraries in their chip design for manufacturing at Tower.

Embedded Processors

To give our customers a low-risk, low-cost, fast time-to-market solution for their system-on-chip, or SoC, designs, we offer them process-optimized silicon-proven embedded processors from world leaders in embedded processors.

ARM.    In November 2002, we joined ARM's Foundry License Program. Through the ARM Program, our customers have gained access to two of ARM's most widely used 32-bit embedded microprocessor cores, or elements, which have been optimized and tested to work on our 0.18-micron manufacturing process. As ARM cores are the most widely used embedded microprocessors today, our agreement with ARM provides our customers a low-risk, low-cost solution for designing and manufacturing advanced ARM-based SoCs at Tower.

51




Ceva.    In December 2001, we signed an agreement with Ceva for the customization of their Teak and XperTeak DSP-core for Tower's 0.18-micron manufacturing process. Under this agreement, Ceva has developed DSP macrocells, which are available for the use of our customers' SoCs from Ceva.

Mixed-signal Technologies

To address a variety of applications for mixed-signal ICs, such as use in cell phones, we have developed strong mixed-signal process capabilities as well as proven mixed-signal IP components.

IMEC.    In January 2002, we entered into a technology transfer and licensing agreement with IMEC pursuant to which we acquired certain advanced analog and mixed-signal process technologies to complement our CMOS process technology capabilities in the 0.18-micron geometry. Pursuant to this agreement, we received a non-exclusive, non-transferable license to manufacture or have manufactured integrated circuits utilizing the technology licensed by IMEC. The mixed-signal offering developed pursuant to this agreement is available to our customers.
Cadence Design Systems.    In order to help our customers meet time-to-market constraints, we are providing them with a seamless transition from design to silicon using Cadence Design Systems Process Design Kit, or PDK. Under our agreement with Cadence Design Systems signed in 2001, Cadence Design Systems has developed a mixed-signal PDK for the use of our mixed-signal customers. PDK is a process specific analog-mixed signal library designed to work with the Cadence Design Systems custom IC tools and can be used to create analog mixed-signal ICs.

Embedded Non-Volatile Memories

To enhance our strength in embedded non-volatile memories in the 0.18-micron process node, we are collaborating with leaders in embedded non-volatile memory technologies to address the market needs in both the high-end and the low-end of the spectrum.

Chipidea Microelectronics.    In January 2003, we entered into a non-exclusive, perpetual, royalty-free license and design agreement with Chipidea Microelectronics, a Portuguese corporation that designs and sells various types of analog and mixed-signal semiconductor intellectual property cores or elements.
Matsushita.    In June 2002, we entered into an agreement with our development partner, Matsushita, for the joint development of 0.18-micron embedded microFLASH technology.
Virage Logic.    In March 2002, we entered into a development agreement with Virage Logic, a company specializing in embedded memory technology. Under this agreement, Virage Logic has successfully developed a suite of SRAM and ROM memory compilers for our 0.18-micron process technology, which are available for licensing by our customers. Presently, multiple customers' products that use Virage Logic's memory products are in production at Fab 2.

Our ability to compete also depends on our ability to operate without infringing the proprietary rights of others. The semiconductor industry is characterized by frequent litigation regarding patent, trade secret and other intellectual property rights. There are no lawsuits currently pending against us regarding the infringement of patents or intellectual property rights of others. However, we have been a party to such claims in the past and because of the nature of the industry, we may continue to receive such communications in the future. We have recently received a notice from a technology company claiming that we and our customers are infringing its patent rights. This notice was followed by an offer to license the technology company's patents for an immaterial one-time license payment, and we have currently concluded a license agreement with this technology company. All other prior claims against us have been resolved through license agreements, the terms of which have not had a material effect on our business. One of these agreements expires at the end of 2005, and we may be unable to extend or renew it on similar terms. In the event any third party were to assert infringement claims against us or our customers, we may have to consider alternatives including, but not limited to:

52




negotiating cross-license agreements;
seeking to acquire licenses to the allegedly infringed patents, which may not be available on commercially reasonable terms, if at all;
discontinuing using certain process technologies, architectures, or designs, which could cause us to stop manufacturing certain semiconductors if we were unable to design around the allegedly infringed patents;
fighting the matter in court and paying substantial monetary damages in the event we were to lose; or
seeking to develop non-infringing technologies, which may not be feasible.

In the event that any third party causes us or any of our customers to discontinue using certain process technologies, we believe that such an outcome would not have a long-term material and adverse effect, as we could design around such technologies.

Environmental Matters

Our operations are subject to a variety of laws and governmental regulations in Israel relating to the use, discharge and disposal of toxic or otherwise hazardous materials used in our production processes. Failure to comply with these laws and regulations could subject us to material costs and liabilities, including costs to clean up contamination caused by our operations.

We are currently operating under a conditional permit from the Israeli Ministry of Environmental Affairs concerning the concentration of fluoride in our wastewater. We believe that we are currently in compliance with the terms of our permit with one exception: we are monitoring the levels of fluoride in accordance with an oral understanding with the Israeli Ministry of Environmental Affairs concerning how often we monitor the levels of fluoride, resulting in our monitoring the levels of fluoride less frequently than required by the written terms of our permit. There have been instances in the past where we were not in compliance with these restrictions, and, despite our best efforts, there may be future instances of non-compliance. We are also in discussions with the Israeli Ministry of Environmental Affairs regarding the possibility of easing of conditions set forth in our permit. If we cannot maintain our compliance with the conditions set forth in our permit or in our other understandings with the Ministry, we may be required to allocate financial resources for the installation of a waste treatment system in order to be in compliance with all the conditions. We estimate that such a waste treatment system would cost approximately $100,000. We believe that we are currently in compliance in all other material respects with applicable environmental laws and regulations.

Employees

(*) Following the commencement of operations of Fab 2 during the third quarter of 2003, most of the employees that prior to that date were classified under Fab 2 construction and technology transfer activities are classified under manufacturing operations activities.

53




We also use temporary employees as necessary. As of September 30, 2003, we had approximately 100 temporary employees.

Except for an arrangement regarding pension contributions, we have no collective bargaining agreements with any of our employees. However, by administrative order, certain provisions of the collective bargaining agreements between the Histadrut (General Federation of Labor in Israel) and the Coordination Bureau of Economic Organizations, relating primarily to the length of the work day, minimum wages, pension contributions, insurance for work-related accidents, procedures for dismissing employees, determination of severance pay and other conditions of employment, are applicable to our employees. In accordance with these provisions, the salaries of our employees are partially indexed to the Consumer Price Index in Israel, depending on the rate of increase of the Consumer Price Index.

We generally provide our employees with benefits and working conditions beyond the minimum requirements. We consider our relationship with our employees to be good, and we have never experienced a labor dispute, strike or work stoppage.

Legal Proceedings

In July 2003, we and several of our directors and shareholders were named as defendants in a securities class action complaint filed in the United States District Court for the Southern District of New York. The plaintiffs have asserted claims arising under the Securities Exchange Act of 1934, alleging misstatements and omissions made by the defendants in materials sent to our shareholders with respect to the approval of an amendment to the investment agreements with our Fab 2 investors. The plaintiffs seek damages in unspecified amounts, which could be substantial, and unspecified rescissory relief. We believe the complaint is without merit and intend to defend ourselves vigorously. Any liability we incur in connection with this complaint could materially harm our business and financial position and, even if we defend ourselves successfully, there is a risk that management distraction in dealing with this complaint could harm our results.

From time to time we are a party to various litigation matters incidental to the conduct of our business. There is no pending or threatened legal proceeding to which we are a party, that, in the opinion of management, is likely to have a material adverse effect on our future financial results or financial condition.

Share Option Plans

General.    We currently maintain 15 share option plans. As of September 30, 2003, there were 6,777,520 options outstanding to acquire our ordinary shares pursuant to our share option plans at a weighted average exercise price of $7.90, exercisable at various dates through September 2013. Options to be granted by us to our directors and employees will only be made pursuant to the 2001 Non-Employee Director Share Option Plan, the 2003/1 Employee Share Option Plan, the 2004 Employee Share Option Plan and the 2005 Employee Share Option Plan.

The purpose of the option plans is to afford an incentive to our officers, directors and employees or of our subsidiary, to acquire a proprietary interest in us, to continue as officers, directors, employees, to increase their efforts on behalf of us and to promote the success of our business.

Administration of Our Share Option Plans.    Our option plans are administered by the Board of Directors. Under the option plans, options to purchase our ordinary shares may be granted to our officers, directors, employees or consultants or our subsidiaries. Under the share option plans, the exercise price of options shall be determined by our Board of Directors, and generally ranges between 85% of market price and market price. The vesting schedule of the options is also determined by the Board of Directors but generally the options vest over a four-year period. Each option granted under the option plans is exercisable until 10 years from the date of the grant of the option plan.

2001 Non-Employee Director Share Option Plan

During 2001, the Audit Committee, Board of Directors and shareholders approved a share option plan pursuant to which our Board members will be granted options to purchase up to 400,000 ordinary shares. As of September 30, 2003, 280,000 options to purchase ordinary shares, of which 240,000 options were exercisable at an exercise price of $8.88 per share, and 40,000 options were exercisable at an exercise price of $6.08 per share, were outstanding under the plan. These options vest over a four-year period, according to various vesting schedules and are generally not exercisable following the fifth anniversary of their vesting date.

2003/1 Employee Share Option Plan

In 2003, we adopted the 2003/1 share option plan and reserved 1,737,420 ordinary shares for issuance to employees (excluding the options issued to our Chairman and Chief Executive Officer under this plan). As of September 30, 2003, options to purchase 1,608,850 ordinary shares were outstanding under the 2003/1 Share Option Plan. This plan also provides for the granting of incentive stock options to those employees qualifying under Section 422 of the Income Tax Code. Options under this share option plan vest in four yearly tranches, instead of three tranches over a period of four years, as in our prior option plans. The exercise prices of the options will generally be the closing sales price of our ordinary shares as reported by Nasdaq. The exercise prices of options granted under the 2003/1 share option plan range from $4.42 to $5.00.

2004 and 2005 Employee Share Option Plans

In December 2003, our shareholders approved three new option plans that will reserve 3.6% of the Company's outstanding share capital, as of November 1 of the year prior to the fiscal year covered by these option plans. The terms of these plans will be materially similar to the terms of the 2003/1 employee share option.

Board Practices

Our Articles of Association provide that the Board of Directors shall consist of at least five and no more than 11 members. All directors hold office until their successors are elected at the next annual general meeting of shareholders. Pursuant to a shareholders agreement described in "Certain Transactions," Israel Corp., SanDisk, Alliance Semiconductor and Macronix have agreed to vote all their respective shares for nominees designated by each shareholder and for the election of a nominee of Israel Corp. as Chairman of the Board. Our officers are appointed by the Board of Directors and (subject, in certain cases, to employment agreement provisions that require 270 days notice of termination) continue to serve at the discretion of the Board of Directors.

Our Articles of Association provide that any director may, by written notice to us, appoint another person to serve as an alternate director, and may cancel such appointment. Any person who is not already a director may act as an alternate, and the same person may not act as the alternate for more than one director at a time. The term of appointment of an alternate director may be for one meeting of the Board of Directors or for a specified period or until notice is given of the cancellation of the appointment.

None of the members of the Board is entitled to receive any severance or similar benefits upon termination of his service with the Board of Directors, other than Mr. Vernia, who is entitled to severance as an employee under Israeli law.

Pursuant to Israeli law, we are required to appoint two independent directors. These directors must be unaffiliated with us and our principals. Any committee of the Board of Directors which is authorized to exercise any function of the board must include at least one independent director.

Independent directors are to be elected by a majority vote at a shareholders' meeting, provided that such majority includes at least one-third of the shares held by non-controlling shareholders voted at the meeting or the total number of shares held by non-controlling shareholders voted against the election of the director does not exceed one percent of the aggregate voting rights in the company.

The initial term of an independent director is three years and may be extended for an additional three years. Independent directors may be removed only by the same percentage of shareholders as is required for their election, or by a court, and then only if the independent directors cease to meet the statutory qualifications for their appointment or if they violate their duty of loyalty to the company.

An independent director is entitled to compensation, as provided in regulations adopted under the new Companies Law, and is otherwise prohibited from receiving any other compensation, directly or indirectly, in connection with service provided as an independent director.

The Companies Law requires public companies to appoint an audit committee. The responsibilities of the audit committee include identifying irregularities in the management of the company's business

59




and approving related party transactions as required by law. An audit committee must consist of at least three directors, including the independent directors of the company. The chairman of the board of directors, any director employed by or otherwise providing services to the company, and a controlling shareholder or any relative of a controlling shareholder, may not be a member of the audit committee.

Under the Companies Law, the board of directors must appoint an internal auditor, who is recommended by the audit committee. The role of the internal auditor is to examine, among other matters, whether the company's actions comply with the law and orderly business procedure. Under the new Companies Law, the internal auditor may be an employee of the company but not an office holder, or an affiliate, or a relative of an office holder or affiliate, and he may not be the company's independent accountant or its representative.

Ms. Simon, who currently serves as an independent director, was appointed under a predecessor law to a fixed five-year term, which expires in September 2004. Mr. Rohrer, who currently serves as an independent director, was appointed under the current Companies Law, with an initial three-year term expiring in April 2005. Both Ms. Simon and Mr. Rohrer serve on our Audit Committee, and Ms. Simon is deemed to be a financial expert as required under the Sarbanes-Oxley Act.

Mr. Ofer, Dr. Harari and Ms. Simon serve on the Stock Option and Compensation Committee. The committee meets at least once a year. The primary function of our Stock Option and Compensation Committee is to approve our employee compensation policy and determine remuneration and other terms of employment for our officers and senior employee. In setting our remuneration policy, the committee considers a number of factors including:

the overall employment market environment;
the basic salaries and benefits available to comparable officers at comparable companies;
the need to attract and retain officers of an appropriate caliber;
the need to ensure such executives' commitment to the continued success of our company by means of incentive schemes;
the performance of the employee; and
financial and operating results of our company.

Share Transfer Restrictions.    Pursuant to a shareholders agreement dated January 18, 2001, as amended, by and among, ICTech, SanDisk, Alliance Semiconductor and Macronix, each of the parties to this shareholders agreement has agreed to restrictions through January 29, 2006 on the transfer of all of our ordinary shares held by them in connection with their investments in Fab 2, subject to the right to sell up to 30% of the number of our ordinary shares held by each respective party beginning on January 29, 2004 through January 29, 2006, during this two-year period. These restrictions are thereafter gradually lifted through January 29, 2008.

Our Fab 2 credit facility also limits the number of ordinary shares which SanDisk, Alliance, Macronix and ICTech may sell while loans under our credit facility are outstanding. The following events are each considered to be a change of our ownership (as such term is defined in the credit facility), any of which would constitute an event of default under the facility agreement:

With respect to ICTech:

From the closing of the amendment on December 16, 2003 through January 29, 2006, ICTech does not hold at least the higher of (i) eight million of our ordinary shares or (ii) 16.5% of our issued share capital less two million ordinary shares;
From the three-year period beginning January 29, 2006 to January 30, 2009, ICTech may gradually sell between 25% to 100% of the shares held by it at the closing of the amendment on December 16, 2003 less the amount of shares it was entitled to sell through January 29, 2006.

With respect to the wafer partners:

At any time during the period between January 30, 2006, and at least 12 months from January 29, 2006, the aggregate shareholdings of SanDisk, Alliance Semiconductor and Macronix is reduced in excess of 40% of the amount of such aggregate shareholdings on January 29, 2006 (in the event certain conditions are met greater reductions in shareholdings are permitted) less the sale of 30% of the number of the ordinary shares held by them on January 29, 2004.

As of December 16, 2003, there were a total of 34 holders of record of our ordinary shares, of which 24 were registered with addresses in the United States. Such United States holders were, as of such date, the holders of record of approximately 34.49% of the outstanding ordinary shares.

62




Certain Transactions

It is our policy to enter into transactions with related parties on terms that, on the whole, are no less favorable than those that would be available from unaffiliated parties. Based on our experience in the areas in which we operate and the terms of our transactions with unaffiliated third parties, we believe that all of the transactions described below met our policy standards at the time they occurred.

Wafer Partner Agreements.    During 2000, we entered into a series of agreements with four wafer partners: SanDisk, Alliance Semiconductor, Macronix and QuickLogic. The wafer partners agreed to invest $250 million in us; SanDisk, Alliance Semiconductor and Macronix each committed to invest $75 million, and QuickLogic committed to invest $25 million in exchange for our ordinary shares and credits towards the purchase of wafers from Fab 2 under the terms set forth in the agreements. We also agreed to reserve approximately 50% of our Fab 2 capacity for our wafer partners for a 10-year period, including during the ramp-up of Fab 2. In addition, these agreements generally provide for a five percent discount on wafer purchases made by the wafer partners of up to 80% of the Fab 2 wafer fabrication capacity committed to the wafer partners, subject to minimum holdings of our ordinary shares.

In April 2002, our shareholders approved amendments to our agreements with our wafer partners and financial investors relating to their third and fourth milestone payments, and in May 2003, our shareholders approved an amendment to our agreements with our wafer partners relating to their fifth milestone payments, which was approved by our shareholders in December 2003 (see — "Amendment to Fifth Milestone Payment Schedule").

To date, we have received an aggregate of $246.8 million from our wafer partners.

Investment by Israel Corporation Technologies (ICTech) Ltd. and other Financial Investors.    In December 2000, Israel Corporation Technologies (ICTech) Ltd., our current principal shareholder and one of Israel's major holding companies, agreed to invest $50.0 million contemporaneous with the investments by the wafer partners. To date, we have received an aggregate of $47.1 million from ICTech, which has been applied to the purchase of 6,330,621 of our ordinary shares and $2.9 million on account of a future issuance of shares in accordance with the amendment to the fifth milestone described below.

In February 2001, the Challenge Fund-Etgar II agreed to invest $5.0 million in our company on substantially the same terms as ICTech. To date, we have received an aggregate of $4.7 million from Challenge, which has been applied to the purchase of 628,261 of our ordinary shares and $0.3 million on account of a future issuance of shares in accordance with the amendment to the fifth milestone described below.

Investment by Ontario Teachers' Pension Plan Board.    In July 2002, Ontario Teachers' Pension Plan Board (OTPP), agreed to purchase from us for $15.0 million, 3,000,000 ordinary shares and 1,350,000 warrants with an exercise price of $7.50, exercisable for four years from the date of issuance. The investment of OTPP was conditioned upon our raising at least an additional $15.0 million by October 31, 2002, which we satisfied through our sale of ordinary shares and warrants pursuant to a distribution of rights to our shareholders and certain employee option holders in September 2002. Pursuant to the share purchase agreement with OTPP, we filed in September 2003 a registration statement with the SEC to register the resale of the shares and warrants issued to OTPP, which was declared effective on September 30, 2003.

Amendment to Fifth Milestone Payment Schedule.    In February 2003, we reached an agreement with our Fab 2 investors to advance the fifth and final Fab 2 milestone payment in two installments. A portion of the first installment amounting to $15.9 million was invested by the Fab 2 investors in May 2003, and they were issued ordinary shares at a purchase price of $2.983 per share.

SanDisk, Alliance Semiconductor, Macronix, ICTech and Challenge invested their remaining $25.1 million due in connection with the fifth milestone payment in December 2003. These parties were issued ordinary shares with respect to the remainder of the first installment ($8.7 million) at the

63




purchase price per share agreed to in the first quarter of 2003 ($2.983 per share) and, with respect to the second installment ($16.4 million), will be issued ordinary shares at the offering price to the public in this offering. In addition, they undertook to perform all actions necessary to bring about the rights offering and/or the rescue offer, which may be initiated by our banks (see "Material Agreements — Credit Facility").

The following chart indicates the approximate aggregate number of ordinary shares to be issued to our Fab 2 investors with respect to the second installment based on offering prices ranging from $5.00 to $10.00:


Offering Price Aggregate Number of
Shares to be Issued
  (in millions)
$  5.00   3.3  
    6.00   2.7  
    7.75   2.1  
    9.00   1.8  
  10.00   1.6  

Wafer Credits.    In connection with their investments in our Fab 2 project, we issued to our major wafer partners non-transferable credits which may be used to reduce the cash amounts to be paid by them when paying for wafers manufactured in Fab 2. These credits could generally be used at a rate of 7.5% for purchases made through June 2005 and 15% for purchases made thereafter. Our major wafer partners have recently agreed that they will not utilize any of their credits, which amount to $41.7 million as of December 29, 2003, for purchase orders of our wafer products from November 11, 2003 until December 31, 2006. From January 1, 2004 to December 31, 2006, each wafer partner is entitled, every quarter, to convert into our ordinary shares those wafer credits that could have been utilized by such wafer partner against the actual payment of wafers manufactured at Fab 2 during such quarter; otherwise, these credits will bear interest payable every quarter at three-month LIBOR plus 2.5% through December 31, 2007. On December 31, 2007, the remaining wafer credits that could have been utilized during this period and that were not converted into shares will be paid to all of the wafer partners who are parties to this amendment. Should the wafer partners elect to convert their wafer credits into our ordinary shares, they will be issued ordinary shares at the average trading price of our ordinary shares during the 15 consecutive trading days preceding the last day of the relevant quarter. For example, if our major wafer partners purchase an amount of wafers which would otherwise result in their using the full amount of credits available to them and they elect to convert all of these credits into ordinary shares, we will issue them an aggregate of 8.3 million shares, assuming the average trading price of our ordinary shares during the 15 consecutive trading days preceding the last relevant quarter is $5.00; if the average trading price of our ordinary shares is $10.00, we will issue an aggregate of 4.2 million shares. We have also agreed to allow our wafer partners to convert, during January 2006, their remaining wafer credits issued in connection with their fourth milestone payment up to an aggregate of $13.2 million, which they may have as of December 31, 2005, into our ordinary shares, at the average trading price of our ordinary shares during the 15 consecutive trading days preceding December 31, 2005. If the wafer partners exercise this right and are issued more than 5%, in the aggregate, of our shares on January 31, 2006, we have agreed to offer all of our other shareholders rights to purchase our shares at the same price per share.

Our ordinary shares to be issued with respect to the fifth milestone payment will be subject to (i) the restrictions on transfer applicable to the investors' other holdings of our ordinary shares in connection with their committed investments, and (ii) registration rights. The transfer restrictions applicable to each of the investors' holdings in our ordinary shares in connection with its committed investments shall be extended by two years to January 2006 with respect to ordinary shares that represent 70% of its holdings in our ordinary shares in connection with (a) its committed investments which are held in January 2004, (b) our September 2002 rights offering, and (c) ordinary shares issued upon the conversion of its wafer credits as described above.

Expense Reimbursement Agreement with Israel Corp.    In March 2002, we entered into an agreement with Israel Corp., the parent company of Israel Corporation Technologies (ICTech), pursuant to which, Mr. Ehud Hillman, a director of our company, provides management services in consideration of an annual fee of $240,000. The term of this agreement is for one year, with automatic renewal for successive one-year periods thereafter, unless prior terminated by one of the parties. Our Audit Committee, Board of Directors and shareholders approved this agreement.

Grant of Options to Ehud Hillman.    In November 2000 and September 2001, we granted to Mr. Hillman, options to purchase up to 50,000 and 21,500 ordinary shares, respectively, at an exercise price of $20.00 and $10.75 per share, respectively, which have all vested. All options granted will remain exercisable for a period of three years from the date of vesting.

Grant of Options to Chairman and Chief Executive Officer.    In May 2003, our shareholders approved the grant of options to Mr. Carmel Vernia, the Chairman of our Board of Directors and Chief Executive Officer to purchase up to 1,043,000 ordinary shares of the Company at an exercise price of $2.983. The options vest over five years, with 417,200 options (40%) vesting on May 31, 2005 and an additional 208,600 options (20%) vesting on May 31st of each of 2006, 2007 and 2008. The vesting of the options is subject to Mr. Vernia's serving as the Chairman of our Board of Directors, Chief Executive Officer or President on the relevant vesting date. Other than as set forth below, the options will be exercisable for a period of 5 years from the date on which the options vest.

Grant of Options to Directors.    During 2001, the Audit Committee, Board of Directors and shareholders approved a stock option plan pursuant to which our Board members will be granted options to purchase up to 400,000 ordinary shares. As of September 30, 2003, 280,000 options to purchase ordinary shares, of which 240,000 options were exercisable at an exercise price of $8.88 per share, and 40,000 options were exercisable at an exercise price of $6.08 per share, were outstanding under the plan. These options vest over a four-year period, according to various vesting schedules and are generally not exercisable following the fifth anniversary of their vesting date.

Indemnification Agreements with Directors.    In December 2001, we entered into indemnification agreements with the members of our Board of Directors, pursuant to which, subject to the limitations set forth in the Israel Companies Law and our Articles of Association, they will be exempt from liability for breaches of the duty of care owed by them to the Company or indemnified for certain costs, expenses and liabilities with respect to events specified in the exemption and indemnification agreements. Such indemnification will be limited to up to 25% of the then current fully paid-in-equity of the Company (in addition to any amounts paid under insurance), with respect to specified events, in each case of indemnification (including all matters connected therewith). The agreements were approved by our shareholders at the general meeting of the shareholders in November 2001 after approval of our Audit Committee and our Board of Directors. In May 2003, our shareholders approved the execution of an exemption and indemnification agreement with Mr. Vernia, under the same terms as the above agreements.

Description of Capital Stock

Our authorized share capital consists of 150,000,000 ordinary shares, par value NIS 1.00 per share. Under our articles of association, the ordinary shares do not have preemptive rights, however, we have granted preemptive rights to a number of our Fab 2 investors which have been waived in connection with this offering. We may from time to time, by approval of a majority of our shareholders, increase our authorized share capital. All ordinary shares are registered shares, rather than bearer shares.

The ownership or voting of our ordinary shares by non-residents of Israel is not restricted in any way by our memorandum of association or articles of association. The State of Israel does not restrict in any way the ownership or voting of ordinary shares by non-residents of Israel, except with respect to subjects of countries that are in a state of war with Israel. Our ordinary shares do not have cumulative voting rights for the election of directors. The affirmative vote of the shareholders present in person or by proxy that represent more than 50% of the voting power present in person or by proxy have the power to elect all nominees up for election to our board of directors.

In the event of our liquidation, after satisfaction of liabilities to creditors, our assets will be distributed to the holders of our ordinary shares in proportion to the nominal value of their respective holdings. This liquidation right may be affected by the grant of a preferential dividend or distribution right to the holder of a class of shares with preferential rights that may be authorized in the future. Dividends may be paid only out of profits, as defined in the Companies Law. Our Board of Directors is authorized to declare dividends, although our bank covenants currently in effect prohibit the payment of dividends on our ordinary shares, unless such payments are approved by the banks.

Holders of ordinary shares have one vote for each ordinary share held on all matters submitted to a vote of shareholders. Subject to the provisions set forth in Section 46B of the Securities Law, these voting rights may be affected by the grant of any special voting rights to the holders of a class of shares with preferential rights that may be authorized in the future. Our major shareholders do not have different voting rights from each other or other shareholders.

Resolutions of shareholders (e.g. resolutions amending our articles of association, electing or removing directors, appointing auditors, authorizing changes in capitalization or the rights attached to our shares or approving a wind-up or merger) require the affirmative vote (at a meeting convened upon advance notice of twenty one days) of shareholders present in person or by proxy and holding shares conferring, in the aggregate, at least a majority of the votes actually cast on such resolutions.

The quorum required for a meeting of shareholders is at least two shareholders present, in person or by proxy, within half an hour of the time fixed for the meeting's commencement that together hold shares conferring in the aggregate more than 33% of the total voting power of our shares. A meeting adjourned for lack of a quorum is adjourned to the same day in the following week at the same time and place. At the reconvened meeting, in the event a quorum is not present within half an hour of the time fixed for the meetings commencement, the persons present shall constitute a quorum.

Our registration number at the Israeli registrar of companies is 52-004199-7. The objective stated in our articles of association is to engage in any lawful activity.

Modification or abrogation of the rights of any existing class of shares requires either the written consent of all of the holders of the issued shares of such class or the adoption of a resolution by an ordinary majority of a general meeting of holders of such class. The quorum required for a class meeting is at least two shareholders present, in person or by proxy, within half an hour of the time fixed for the meetings commencement that together hold shares conferring in the aggregate at least 33% of the total voting power of the issued shares of such class. If no quorum is present, the meeting shall be adjourned to another time and at the adjourned meeting a quorum shall be constituted in the presence of any number of participants, regardless of the number of shares held by them.

As of December 29, 2003, 51,696,097 of our ordinary shares were outstanding. The above number of outstanding ordinary shares does not include 1,300,000 treasury shares held by us in an account with Bear Stearns & Co.

The transfer agent and registrar for our ordinary shares is American Stock Transfer & Trust Company, 59 Maiden Lane, New York, New York 10007.

Taxation and Government Programs

The following is a summary of the material current tax structure applicable to companies in Israel, with special reference to its effect on us. The following also contains a discussion of the material Israeli and United States tax consequences to persons purchasing our ordinary shares offered by this prospectus and of Israeli government programs benefiting us. To the extent that the discussion is based on new tax legislation that has not been subject to judicial or administrative interpretation, we cannot assure you that the tax authorities will accept the views expressed in the discussion in question. The discussion is not intended, and should not be taken, as legal or professional tax advice and is not exhaustive of all possible tax considerations.

WE RECOMMEND THAT IN ADDITION TO REVIEWING THE DISCUSSION BELOW, PROSPECTIVE PURCHASERS OF OUR ORDINARY SHARES CONSULT THEIR OWN TAX ADVISORS CONCERNING THE UNITED STATES, ISRAELI OR OTHER TAX CONSEQUENCES TO THEM, BASED UPON THEIR PARTICULAR CIRCUMSTANCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF ORDINARY SHARES, INCLUDING, IN PARTICULAR, THE EFFECT OF ANY FOREIGN, STATE OR LOCAL TAXES.

General Corporate Tax Structure

In general, Israeli companies are currently subject to Company Tax at the rate of 36% of taxable income. However, the effective tax rate payable by a company, which derives income from an Approved Enterprise (as further discussed below), may be considerably lower.

Law for the Encouragement of Capital Investments, 1959

Our facilities, including Fab 2, have been granted "Approved Enterprise" status under the Law for the Encouragement of Capital Investments, 1959, as amended (the "Investment Law"). The Investment Law provides that a capital investment in eligible facilities may, upon application to the Israel Investment Center, be designated as an Approved Enterprise. Each certificate of approval for an Approved Enterprise relates to a specific investment program delineated both by its financial scope, including its capital sources and its physical characteristics, e.g., the equipment to be purchased and utilized pursuant to the program. The tax benefits derived from any such certificate of approval relate only to taxable income attributable to the specific Approved Enterprise.

Taxable income of a company derived from an Approved Enterprise is subject to Company Tax at the rate of 25% (rather than 36% as stated above) for the "Benefit Period": a period of seven years commencing with the year in which the Approved Enterprise first generated taxable income (limited to twelve years from commencement of production or fourteen years from the date of approval, whichever is earlier) and, under certain circumstances (as further detailed below and applicable to us), extending to a maximum of ten years from the commencement year. Notwithstanding the foregoing, taxable income of a company located in certain geographic locations in Israel, derived from an Approved Enterprise approved after January 1, 1997, which is the case with respect to Fab 2, which is not distributed to its shareholders, is tax exempt for the first two years of the Benefit Period and is taxed at a rate of 25% for the remainder of the Benefit Period. In the event that a company is operating under more than one approval or that only part of its capital investments are approved (a "Mixed Enterprise"), its effective Company Tax rate is the result of a weighted combination of the various applicable rates.

A company, which qualifies as a "Foreign Investors' Company," is entitled to further reductions in the tax rate normally applicable to Approved Enterprises. Such benefits will be granted only to enterprises seeking approval not later than December 31, 2002. Subject to certain conditions, a "Foreign Investors' Company" is a company which has more than 25% of its combined shareholders' investment in share capital (in terms of rights to profits, voting and the appointment of directors) and in long term shareholders' loans made by persons who are not residents of Israel. The percentage owned by nonresidents of Israel for any tax year will be determined by the lowest percentage of any

of the above rights held by nonresidents during that year. Such a company will pay Company Tax at reduced rates for an extended ten-year (rather than the otherwise applicable seven-year) period and is exempt from any other tax on the undistributed income from its Approved Enterprise.
