The Company develops and sells solutions designed to optimize the reverse link of wireless networks. Reverse link is the signal from the mobile device (e.g., mobile phone) to the base station. Its array of solutions includes its ANF product line (adaptive notch filter, “ANF”^™), the new RF² product line (reverse link radio frequency fidelity, “RF²”^™), services and other solutions, all focused on optimizing the reverse link.

The benefits of using the Company’s solutions include: allowing carriers (channels) to carry traffic in certain circumstances where they cannot do so, increased cell site capacity and utilization, easier location of new cell sites due to tolerance of interference, reduced mobile transmit power and thus improved battery life, improved voice quality and substantial reduction in dropped calls and failed attempts, culminating in more satisfied customers and increased revenues for wireless operators. These benefits have been documented in field trials and commercial deployments with wireless operators involving existing wireless systems.

In addition, the Company believes that upgrades of existing wireless networks to allow for data throughput (“2.5G” systems) and further, by the rollout of the next generation of wireless systems (“3G” or “3rd Generation”), operators will need to manage and eliminate interference more effectively in order to meet their performance objectives. The Company believes that with the increased data bit rates required of these systems and the increased usage of these systems due to the “wireless internet”, that interference levels will increase substantially while tolerance to interference will decrease substantially, thereby requiring an improved filtering system in the base station. The Company believes that its products can be an effective element of that solution.

One of the difficult tasks facing any wireless operator is the need to resolve interference that is from multiple sources, sporadic or quickly moving. Often, sources of interference prove difficult to locate due to their sporadic nature, and other times are uncontrollable (such as in the case of border sites). Regardless, in-band interference is a fast-growing problem, one that can substantially reduce the ability of the network to carry traffic.

With the acquisition of the ANF (Adaptive Notch Filter) division of Lockheed Martin Canada Corporation during 2000 and subsequent development efforts, the Company owns proprietary technologies to produce filters that monitor RF spectrum and block spontaneous interference occurring within that spectrum. This allows the Company to offer what it believes to be the only product in the world that locates and suppresses in-band interference in a CDMA carrier within 20 milliseconds.

The Company has announced the expansion of the ANF platform to support network-wide deployment in metropolitan service areas. The more flexible platform now has the capability to scan and protect any combination of CDMA carriers in either A-band or B-band cellular networks, along with a web-based network management software package to allow operators to remotely monitor and manage large numbers of sites equipped with ANF technology. This web-based reporting tool has been well-received by customers as a valuable tool for their use in managing their networks, and thus provides a strong competitive advantage to the ANF product line.

Based on customer feedback, the Company has further reinvented and refined its ANF^™ product line to include an “ANF on Wheels”. This is a rapidly deployable solution to combat immediate problems that also serves as a state-of-the-art reporting tool. Operators can utilize the reporting features of this product to gain critical information of interference events within their networks.

The Company launched its RF² product line during September 2003, and received commercial orders during the fourth quarter 2003. Designed for network-wide deployment, the RF² drastically reduces the noise figure in a base station, improving the ability of a base station to optimally process wireless signals. The impact of RF² is also felt on the handset in the form of reduced mobile transmit power and increased talk time while improving base station coverage. As a result, operators have fewer dropped calls, fewer connection failures, and most importantly, more satisfied customers. The RF² is only a fraction of the cost of higher-priced solutions, such as HTS units (High Temperature Superconductor filters), yet has been shown to deliver performance which is generally comparable with HTS.

The Company also has a number of HTS (High Temperature Superconductor filter) solutions available for the proper application, but has focused on the RF² as a value leader in the industry.

Over time, the Company has developed expertise in the area of reverse link issues, including interference mitigation. This expertise is provided to customers in the form of interference audits and analytical tools, thus allowing customers to focus their resources on running their networks instead of focusing on understanding interference problems.

The Company was founded in 1989 by ARCH Development Corporation, an affiliate of the University of Chicago, to commercialize superconductor technologies initially developed by Argonne National Laboratory. The Company was incorporated as Illinois Superconductor Corporation in Illinois on October 18, 1989 and reincorporated in Delaware on September 24, 1993. The Company shifted its focus from that of a superconductive filter provider to a customer-driven interference management Company during 2001, changing its name to ISCO International, Inc. More recently, the Company has broadened its view to the optimization of the reverse link of wireless networks (reverse link is the signal from the mobile device to the base station). The Company’s facilities and principal executive offices are located at 451 Kingston Court, Mt. Prospect, Illinois 60056 and its telephone number is (847) 391-9400. The Company maintains a website at http://www.iscointl.com. The information contained therein is not incorporated into this annual report.

The Company’s strategic goal is to become the leading supplier of reverse link optimization solutions to wireless operators. ISCO is seeking to accomplish its goal by:

The Company is focusing its continuous efforts on winning the support of the world’s leading wireless operators for its reverse-link optimization solutions. The Company believes that its ANF^™ products and RF²^™ products, as well as its professional service support and other products, make it the reverse link specialist in the market. In addition, the Company recently started providing services to operators who need expert advice on understanding and controlling interference and other aspects of their networks.

The Company believes it holds a highly comprehensive intellectual property portfolio in reverse link optimization technology (more than 100 patents issued or pending).

The Company currently outsources production for its products. Management believes that it can maintain or achieve targeted product gross margins and minimize capital needs while reducing product costs. Management believes that offering the lowest product cost will further strengthen the Company’s ability to achieve its strategic objectives.

Reverse link issues are a growing problem limiting cell site coverage, capacity and range, as well as mobile transmit power and related battery-life issues. Reverse link problems cause dropped calls, poor call quality, and other service problems that lead to subscriber dissatisfaction and turnover (churn). Interference enters a carrier’s operating frequencies from such sources as: home electronic devices such as portable phones, two-way radios used by commercial enterprises and governmental agencies, air-to-ground radio, police, fire and emergency services radio, military radio, wireless data networking systems, television and radio broadcasts, radar and other cellular networks. Interference is also created by electrical sources used to power cellular base station equipment. Interference may begin within a particular frequency or migrate from another frequency. Increased usage of co-location (multiple providers using the same towers), increased sensitivity of non-voice applications, and the continued surge in wireless traffic result in increasing the impact of Interference on wireless networks.

The Company believes the proliferation of wireless devices and high data rate services will exacerbate the amount of interference bombarding carriers’ operating frequencies. Conventional cellular base station equipment does not effectively cope with interference issues.

In the face of expanding subscriber bases, increased minutes of cell phone use, demand for high data rate services, the ease of customer churn due to number portability, restricted capital budgets and intense competition, the provisioning and optimization of wireless system infrastructure is a major challenge for operators. As a result of these industry conditions, wireless equipment manufacturers, including independent wireless technology companies and large original equipment manufacturers (OEM’s) are working intensely to develop technologies that provide operators the tools necessary to monetize the growing demand for wireless services.

Using the Company’s filtering solutions to optimize the reverse link aspect of the wireless network, including the mitigation of interference, the Company believes that operators can capture additional capacity and utilization, expand cell site range and coverage as well as reduce dropped calls to a fraction of what they were prior to the addition of the Company’s equipment and to drastically improve overall call quality. Further, the addition of data has placed a tremendous strain on wireless networks, and the Company has encountered cases where its products enabled carriers (channels) to carry traffic where they could not do so without the Company’s solutions. These issues, capacity and quality, have been presented as critical wireless operator issues in today’s environment.

The Company estimates the economic payback to operators as a result of the use of the Company’s filtering solutions should occur in less than one year, depending on cell site traffic levels and dynamics. The Company believes that the short economic payback of its equipment as opposed to other interference control solutions as well as the relatively low capital cost of the Company’s products make it’s products the best value of all alternatives to system operators.

The higher data rates of 2.5G systems (currently coming online) and 3G systems (up to 10 to 100 times faster than current 2G networks), will require much cleaner signals to support IP protocols (error rates typically 1,000 to 10,000 times better than current 2G specifications). As a result, management believes that system operators will eventually utilize its solutions in a large number of their base stations.

The Company believes demand for its products will be primarily driven by the following factors:

1. Existing 2G networks are straining under heavy traffic. According to the Cellular Telecommunications & Internet Association, minutes per user per month increased from 136 minutes in 1998 to 403 minutes in 2002. According to industry sources, the worldwide number of subscribers using mobile wireless networks is expected to increase from 308 million in 1998 to almost 1 billion in 2004, representing an annual compound growth rate of 21%. Regardless of the timing of the introduction of high data rate 2.5G and 3G systems, these trends will drive demand for infrastructure enhancements.

2. As wireless operators install their data-oriented 2.5G overlay networks on top of their existing 2G network, the Company believes data-networks will further strain system capacity resulting in the need for enhanced front-end systems to optimize the reverse link in order to achieve data and error rates specified.

3. Interference is a primary cause of poor call quality, dropped and lost calls. The Company believes that as a result of increasing use of devices such as cellular phones, wireless data networking equipment, wireless consumer appliances and radar, wireless network operators are coming to view interference management technologies as necessary to protect against their customer bases migrating to other carriers (churn), an especially sensitive topic since number portability (the ability to retain one’s phone number when changing wireless operators – historically a barrier to changing providers) went into effect.

4. The Company believes that 3G wireless networks will require smaller operating cells and more base stations than existing cellular networks in order to cover the same geographic area. This is based on the requirement for high data rate transmission capability and cleaner error code criterion for 3G networks as well as the fact that transmissions at higher frequencies utilized by 3G networks (expected to operate in the 2100 MHz range) have shorter transmission waves as compared to lower frequency transmissions. Shorter transmission waves tend to limit the distance transmissions can travel without significant degradation.

Existing wireless networks are based on technical architectures that were standardized in the late 1980s and early 1990s, and are highly optimized for voice signals. The guiding principle of 2G systems (including TDMA, GSM, CDMA) is signal compression to achieve spectrum efficiency. The basic user data-rate in these networks is typically around 10 kb/s, which is adequate for telephony voice traffic.

3G standards are being developed to meet the needs for a true wireless Internet service. (There are several competing versions of the 3G standard, including W-CDMA and cdma2000. These standards are broadly similar. They are based on wideband CDMA architecture, and will require the same general ultra-clean interference suppression solutions.) These new standards will allow for user data-rates of up to 2 MB/s — nearly two hundred times faster than previous 2G networks. Moreover, 3G networks will have to support traffic patterns characteristic of Internet connectivity (“always on” service that may generate several hours of connect time per user per day) rather than today’s short voice telephony patterns.

One system element that is especially affected by 3G performance objectives is the receiver front-end, that acquire the desired signal and block interference from other sources. Existing 1G and 2G networks are designed around the less-than-perfect performance characteristics of conventional front-end systems based. These systems allow for a great deal of interference to penetrate the desired signal. There is evidence that even in existing networks (2G CDMA) there are large losses in system capacity — more than 50% of nominal capacity lost in many cases, according to recent tests with major CDMA carriers — due solely to the imperfections in receiver front-end filtering based on conventional technology. With 3G, extensive testing by NTT DoCoMo and others indicates that conventional front-end technology may not deliver adequate performance.

The Company believes itself to be a highly effective reverse link optimizer. The Company’s goal is to position itself to lead the industry in reverse link optimization applications within wireless systems. For example, ISCO’s ANF product line is a unique technology that mitigates interference effects, including those that originate inband, one of the most dominant factors in affecting service providers network quality.

A wireless base station is divided (roughly) into two halves: the digital portion, and the so-called “front-end.”

The core expertise of ISCO is the application of technology and experience to wireless front-end systems. The components in the receiver front-end are designed to acquire the desired information-bearing signal and pass it through to the digital portion of the system, where it is processed digitally and the user information is extracted. Typically, much of the signal is lost as it passes through the front-end components. As well, undesired electromagnetic interference (inband and out of band) also leaks into the system due to imperfections in the filtering characteristics of the front-end devices.

The use of ISCO solutions for wireless front-end systems is based on creating front-end components which block or mitigate the impact of interference, optimize signal processing within the receive path while introducing very little signal loss or degradation, and help operators identify and resolve issues impacting performance.

The Company launched a new product line, not based on superconductivity, that optimizes front-end performance. ISCO has developed a cost-effective solution that greatly enhances wireless base station performance. The RF² product is a reverse link low noise front-end solution developed out of ISCO’s years of experience with radio frequency and wireless base station performance needs. The RF² product is designed and priced for network wide deployment, improving base station coverage integrity and eliminating dead zones. The impact of RF² is also felt on the handset in the form of reduced mobile transmit power and increased talk time while improving base station coverage. As a result, operators have fewer dropped calls, fewer connection failures, and most importantly, more satisfied customers.

The RF² is easy to install, maintenance-free, and a fraction the cost of HTS solutions. Additionally, it has been shown to deliver results generally comparable to HTS without a cryogenic cooler or other moving parts.

OEM competition include solution such as adding a carrier to the CDMA cell sites (to increase capacity), cell splitting, or even adding an entirely new base station so as to add capacity and coverage. After-market competition includes repeaters, tower-mounted amplifiers, and HTS receiver front ends. As with the OEM-based solutions, these products may generally improve the coverage of the network.

The Company offers adaptive notch filter products, not based on superconductivity, that continually scan a segment of RF spectrum for interference and block that interference within 20 milliseconds per carrier (channel). The blocking feature is in place as long as needed for noise suppression. These products are especially useful in dealing with sporadic in-band interference as they adapt the Company’s interference-management technology to the fluid environment. The complementary nature of these products with the Company’s RF² solutions to offer complete reverse link optimization solutions to its customers, rather than force customers to try to isolate the primary cause of their problems prior to looking for an effective solution.

ISCO’s ANF product substantially reduces or eliminates altogether the effects of such in-band interference. Each ANF unit continuously monitors up to all seven available CDMA carriers (or seven 1.25MHz channels) being utilized for service, identifying and eliminating narrow-band interferers within the channel whenever and wherever they occur. By dynamically notching out this in-band interference, the coverage integrity and supportable capacity of the cell site are maintained as designed during the network build out. As a direct consequence, the ANF product thereby recovers lost minutes of use, reduces the number of dropped calls and failed call attempts. An entire network of ANF hardware can be managed via the web-based management software that supports the hardware.

The current product is focused on CDMA networks. A product evolution path is planned to extend the range of applications to wide-band CDMA systems (W-CDMA). Other items that will be addressed during future product development include a higher level of integration and a modular design, resulting in a more compact and less expensive product with enhanced functionality, as well as configuration for an outdoor application

ISCO’s Adaptive Notch Filter (ANF) unit dynamically identifies and eliminates direct in-band interference in the reverse link of a wide-band system such as CDMA. When such interference is present without being eliminated, the reverse link of such a system will be significantly reduced, often to the point of not allowing any calls on the entire CDMA channel. The ANF unit continuously monitors the power spectral density across the CDMA carriers in use and identifies narrow-band interference in the band of interest. The severity of multiple in-band interferers is prioritized, and the ANF unit dynamically inserts a highly selective notch to eliminate up to three interferers with minimal impact on the desired broadband signal. A single ANF unit supports both the main and diversity paths of a single sector within the cell sites.

ISCO has also developed a network-wide, web-based network management tool (web monitor), allowing its customers to perform management functions for all ANF units throughout the system. This tool with a graphical user interface allows the service provider to control, configure, and monitor the ANF units remotely from the network management center. This includes:

ISCO has industry leading expertise in the design, deployment and optimization of CDMA networks. To facilitate rapid penetration of ANF, ISCO is offering professional services to the service providers engineering team to identify and quantify interference, and, its effects on network performance. ISCO has already developed the following custom software and hardware tools to perform interference analysis and interference audit. iSMART (Interference from System Metric Analysis Rules Tool): This software tool enables a service provider to identify potential ANF candidate sectors/cell sites by analyzing the system performance metrics data generated in their CDMA network. Automated Test Equipment, ANF-on-wheels and ANF Web Monitor: This software/hardware combination affords us the ability to perform interference audit at cell sites of service providers regardless of the frequency band of operation. This service helps quantify interference and identify new markets (frequency bands) with high interference.

ISCO has a proprietary technology on ANF but there are alternative solutions that can be categorized as either direct or indirect competition. Direct competition is defined as products that directly address the problem of the issue at hand, namely in-band interference. Indirect competition is categorized as other wireless communication products that do not directly solve the problem of in-band interference, but may be perceived as an alternate solution by service providers. For purposes of this document, the base-station manufacturers will be referred to as the OEMs, whereas manufacturers of auxiliary equipment to augment the base station will be referred to as After-Market Vendors.

Fixed-frequency notch filters are the main form of direct competition. However, these will only work in a static interference environment, and hence do not satisfy the need of dynamic interference detection and elimination as observed in a vast majority of in-band interference scenarios. Finally, smart antennas were also developed with the intent of in-band interference mitigation. However, the Company believes these solutions have limited applicability and effectiveness in eliminating in-band interference, particularly in a CDMA-based network, and are typically substantially more expensive (in addition to being less effective) than ISCO’s ANF solution.

Digital-signal-processing based solutions may be under development by the various OEMs. Even if the manufacturers do develop such a solution for in-band interference, the Company believes that they would have limited dynamic range and hence would only be able to mitigate low-power interference. (This has been confirmed, through discussions with a major OEM, which was interested in incorporating ISCO’s ANF product in addition to their own DSP-based solution, so that the ANF product could eliminate the effects of high-power interference.)

Indirect competition does not directly address the problem of in-band interference, but could be viewed as a method for circumventing the problem without addressing the issues at hand. Some of these are based solely on OEM-based hardware, such as adding a carrier to the CDMA cell sites (to increase capacity), cell splitting, or even adding an entirely new base station so as to add capacity and higher signal-to-noise in a particularly problematic location. However, the Company believes these solutions to be very costly, and, while providing more absolute network capacity, do not guarantee increased performance due to the limiting effects of in-band interference.

Other forms of indirect competition include repeaters, tower-mounted amplifiers, and HTS receiver front ends. As with the OEM-based solutions, the Company does not believe these to directly address the problem of in-band interference, but may generally improve the coverage of the network.

The Company’s products are designed to address the high performance RF front-end needs of domestic and international commercial wireless telecommunication systems by providing the following advantages:

Greater Network Capacity and Utilization. The Company’s solutions can increase capacity and utilization by up to 70% or more. In some cases, capacity increases because channels which were previously unusable due to interference are recovered. In other cases, system utilization increases because of lower levels of blocked or dropped calls, and increases in the ability of the system to permit weak signals to be processed with acceptable call quality. In CDMA systems, increased capacity frequently results from lowering the system’s noise floor.

Improved Base Station Range. The Company’s RF front-end systems can extend the uplink range of a wireless system by up to 30% or more. Greater range can reduce a service operator’s capital expenditure per customer in lower density areas by filling in coverage gaps in existing systems or by reducing the number of required cell sites for new system deployments.

Improved Flexibility in Locating Base Stations. The Company’s RF front-end products can allow wireless telecommunications service providers to collocate base stations near other RF transmitters. The Company’s products allow the base station radio to better tolerate RF interference while reducing out-of band signals that could interfere with other nearby wireless telecommunication operators.

Improved Call Quality – Fewer Dropped Calls and Failed Connection Attempts. The Company’s products improve call quality by reducing dropped and blocked calls. During commercial installations, the Company’s RF filter products have demonstrated drastic reduction in dropped calls, by as much as 50% or more. The Company’s products similarly reduce the number of ineffective connection attempts and dead zones within networks.

Improved Digital System Capacity. Tests conducted by wireless operators show that on a single base station test, capacity of the base station increases by as much as 30%. The Company believes that with a system wide deployment of its products, the capacity of the system may increase by more than 70%. Additionally, cases have been presented where a carrier (channel) could not carry data traffic without an ANF^™ solution.

Reduced Mobile Transmit Power. By improving the reverse link, reducing the system’s noise floor and mitigating the destructive impact of interference, the Company’s solutions greatly reduce required mobile transmit power. This improves battery life, among other benefits.

Until recently, the Company had historically focused its sales and marketing effort on U.S. wireless service providers for retrofit applications. To date, the Company has sold its products to many of the largest cellular operators in the United States as well as to numerous mid-size and smaller U.S. wireless operators.

Recently, the Company has started targeting certain international customers, marketing both its existing products and presenting the benefits of its interference-management technology in the design and early stages of new systems for 2.5G and 3G Systems.

The Company emphasizes the outsourcing of its manufacturing processes in order to provide predictable product yields and can be easily expanded to meet increased customer demand. Toward that end, the Company currently produces all of its ANF^TM products through third party manufacturer and designed its RF² product for similar production. The Company believes there are multiple sources available for manufacturing and foresees no problem in future production runs built externally.

The Company’s internal manufacturing capability can be found in Mount Prospect, IL.

The Company’s R&D efforts have been focused on developing and improving RF products for wireless telecommunications systems. As a result of such efforts, product performance has been improved, product size has been reduced, production costs have been lowered, product functionality has been increased, and product packaging has been streamlined. While the Company expects to continue to invest in R&D to further improve and adapt its products to meet and exceed market expectations, this is expected to require significantly less capital than in the past as it is now primarily a matter of improving existing products as opposed to the initial development of those products. The Company also intends to develop related products that are synergistic with its core filter offerings and which utilize the Company’s core technical competencies in the interference-management arena.

The Company’s total R&D expenses during 2001, 2002 and 2003 were approximately $7,132,000, $2,737,000, and $988,000 respectively.

The Company regards certain elements of its product design, fabrication technology and manufacturing process as proprietary and protects its rights in them through a combination of patents, trade secrets and non-disclosure agreements. The Company also has obtained exclusive and non-exclusive licenses for technology developed with or by its research partners, Argonne National Laboratory (“Argonne”) and Northwestern University, and expects to continue to obtain licenses from such research partners and others. The Company believes that its success will depend in part upon the protection of its proprietary information, its patents and licenses of key technologies from third parties, and its ability to operate without infringing on the proprietary rights of others.

There are two ways of designing an HTS component. So-called thin-film techniques use vacuum deposition processes to carefully lay down extremely thin layers of HTS material upon an appropriate substrate. The result is a wafer which can be etched to create components such as a filter, in a process similar to semi-conductor chip fabrication. The advantages of thin-film techniques are a somewhat smaller size of the filter component, and the potential for integration with other components in an Integrated Circuit or chip-type architecture.

Thick-film techniques use a series of processes more similar to the ceramic firing of a coating to create a somewhat thicker HTS layer on the substrate, and are typically employed to coat three-dimensional resonator elements and other larger structures. The manufacturing process is generally much simpler and less expensive (no clean room required as for thin-film). The advantages of thick-film HTS are much higher filter performance (i.e., better selectivity and ultimate rejection; much better intermodulation characteristics; larger numbers of poles can be employed.) as well as the ability to support high-power applications for transmit filters and other transmitter components. ISCO is the only company with intellectual property covering both technologies.

As of December 31, 2003, the Company had been issued more than 100 patents and patent applications, with no licenses of patents and patent applications held by others. The Company acquired patents, through assignment of a license from the Canadian government, in connection with the purchase of the Adaptive Notch Filtering business unit of Lockheed Martin Canada. One of the Company’s patents is jointly owned with Lucent Technologies, Inc. The Company believes that a large number of patent applications have been filed worldwide, and

many patents have been granted in the U.S. relating to HTS materials. The claims in those patents often appear to overlap and there are interference proceedings pending in the United States Patent and Trademark Office (not currently involving the Company) regarding rights to inventions claimed in some of the HTS materials patent applications. Furthermore, the Company expects to pursue foreign patent rights on certain of its inventions and technologies critical to its products.

Although the Company believes that its wireless telecommunications products themselves are not licensed or governed by approval requirements of the Federal Communications Commission (“FCC”), the operation of base stations is subject to FCC licensing and the radio equipment into which the Company’s products would be incorporated is subject to FCC approval. Base stations and the equipment marketed for use therein must meet specified technical standards. The Company’s ability to sell its RF filter products is dependent on the ability of wireless base station equipment manufacturers and of wireless base station operators to obtain and retain the necessary FCC approvals and licenses. In order to be acceptable to base station equipment manufacturers and to base station operators, the characteristics, quality, and reliability of the Company’s base station products must enable them to meet FCC technical standards.

The Company may use certain hazardous materials in its research, development and any manufacturing operations to the extent it manufactures product in the future. As a result, the Company is subject to stringent federal, state and local regulations governing the storage, use and disposal of such materials. It is possible that current or future laws and regulations could require the Company to make substantial expenditures for preventive or remedial action, reduction of chemical exposure, or waste treatment or disposal. The Company believes it is in material compliance with all environmental regulations and to date the Company has not had to incur significant expenditures for preventive or remedial action with respect to the use of hazardous materials.

As of January 15, 2004, the Company had a total of 18 employees, 4 of whom hold advanced degrees. Of the employees, 2 are engaged in manufacturing and production, 7 are engaged in research, development and engineering, and 4 are engaged in marketing and sales, and 5 are engaged in finance and administration. Additionally, a former employee now provides consulting services within the marketing function. The Company also periodically employs other consultants and independent contractors on as as-needed basis. None of the Company’s employees are covered by a collective bargaining agreement. The Company believes its relationship with its employees is good.

Because ISCO International, Inc. (“ISCO” or “ISCO International” or “Company”) wants to provide investors with more meaningful and useful information, this Annual Report on Form 10-K (“Form 10-K”) contains, and incorporates by reference, certain forward-looking statements that reflect the Company’s current expectations regarding its future results of operations, performance and achievements. The Company has tried, wherever possible, to identify these forward-looking statements by using words such as “anticipates,” “believes,” “estimates,” “expects,” “designs,” “plans,” “intends” and similar expressions. These statements reflect the Company’s current beliefs and are based on information currently available to the Company. Accordingly, these statements are subject to certain risks, uncertainties and contingencies, including the factors set forth under the caption “Risk Factors,” which could cause the Company’s actual results, performance or achievements for 2004 and beyond to differ materially from those expressed in, or implied by, any of these statements. You should not place undue reliance on any forward-looking statements. Except as otherwise required by federal securities laws, the Company undertakes no obligation to release publicly the results of any revisions to any such forward-looking statements that may be made to reflect events or circumstances after the date of this prospectus or to reflect the occurrence of unanticipated events.

The following factors, in addition to other information contained herein, should be considered carefully in evaluating the Company and its business.

History of Losses Raises Doubts About Ability to Continue as a Going Concern

The Company was founded in October 1989 and through 1996 was engaged principally in research and development, product testing, manufacturing, marketing and sales activities. It has incurred net losses since inception. As of December 31, 2003, the accumulated deficit was approximately $150.1 million. The Company has only recently begun to generate revenues from the sale of its ANF and RF² products. Accordingly, although management has announced the expectation of improvement during 2004, it is nonetheless possible that the Company may continue to experience net losses and cannot be certain if or when the Company will become profitable.

These conditions raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying consolidated financial statements have been prepared assuming the Company will continue a going concern and do not include any adjustments relating to the recoverability of reported assets or liabilities should the Company be unable to continue as a going concern.

To date, the Company has financed its operations primarily through public and private equity and debt financings, and most recently through financings with affiliates of its two largest shareholders. The Company believes that it has sufficient funds to operate its business as identified herein through 2004, provided that the Company is able to borrow the $1 million remaining under the uncommitted line of credit with affiliates of its two largest shareholders, Elliott Associates, L.P. (Manchester Securities Corporation) and Alexander Finance, L.P. This line is uncommitted, such that the additional borrowing under the facility is subject to the approval of the lenders. Without this credit line, the Company believes it has funds available into the third or fourth quarter 2004, and quite possibly longer, subject to operating results. The Company intends to look into augmenting its existing capital position by utilizing the unused portion of the credit line as identified and through other sources of capital.

The Company’s continued existence is therefore dependent upon its continued ability to raise funds through the issuance of its securities or borrowings, and its ability to acquire assets or satisfy liabilities by the issuance of stock. Management’s plans in this regard are to obtain other debt and equity financing until such time as the Company profitable operation and positive cash flow are achieved and maintained.

Although management believes, based on the fact that it has raised funds through sales of common stock and from borrowings over the past several years, that it will be able to secure suitable additional financing for the Company’s operations, there can be no guarantee that such financing will continue to be available on reasonable terms, or at all. As a result, there is no assurance that the Company will be able to continue as a going concern.

The actual amount of future funding requirements will depend on many factors, including: the amount and timing of future revenues, the level of product marketing and sales efforts to support the Company’s commercialization plans, the magnitude of research and product development programs, the ability to improve or maintain product margins, the cost of additional plant and equipment for manufacturing, if needed, and the costs involved in protecting patents or other intellectual property.

For the Company to be financially successful, it must either manufacture its products in substantial quantities, at acceptable costs and on a timely basis or enter into an outsourcing arrangement with a qualified manufacturer that will allow it the same. Currently, the Company’s manufacturing requirements are met by third party contract manufacturers. The efficient operation of the Company’s business will depend, in part, on its ability to have these and other companies manufacture its products in a timely manner, cost–effectively and in sufficient volumes while maintaining the required quality. Any manufacturing disruption could impair the Company’s ability to fulfill orders and could cause us to lose customers.

In the event that it is unable to enter into a manufacturing arrangement on acceptable terms with a qualified manufacturer, the Company would have to produce the products in commercial quantities in its own facilities.

Although to date the Company has produced limited quantities of its products for commercial installations and for use in development and customer field trial programs, production of large quantities of its products at competitive costs presents a number of technological and engineering challenges. The Company may be unable to manufacture such products in sufficient volume. The Company has limited experience in manufacturing, and substantial costs and expenses may be incurred in connection with attempts to manufacture larger quantities of the Company’s products. The Company may be unable to make the transition to large-scale commercial production successfully.

The Company’s sales and marketing experience to date is very limited. The Company may be required to further develop its marketing and sales force in order to effectively demonstrate the advantages of its products over other products. The Company also may elect to enter into arrangements with third parties regarding the commercialization and marketing of its products. If the Company enters into such agreements or relationships, it will be substantially dependent upon the efforts of others in deriving commercial benefits from its products. The Company may be unable to establish adequate sales and distribution capabilities, it may be unable to enter into marketing arrangements or relationships with third parties on financially acceptable terms, and any such third party may not be successful in marketing the Company’s products. There is no guarantee that its sales and marketing effort will be successful.

Growth may cause a significant strain on the Company’s management, operational, financial and other resources. The ability to manage growth effectively may require the Company to implement and improve its operational, financial, manufacturing and management information systems and expand, train, manage and motivate employees. These demands may require the addition of new management personnel and the development of additional expertise by management. Any increase in resources devoted to product development and marketing and sales efforts could have an adverse effect on financial performance in future fiscal quarters. If the Company were to receive substantial orders, it may have to expand current facilities, which could cause an additional strain on the Company’s management personnel and development resources. The failure of the management team to effectively manage growth could have a material adverse effect on the business, operating results and financial condition.

The market price of the Company’s common stock, like that of many other high-technology companies, has fluctuated significantly and is likely to continue to fluctuate in the future. Since January 1, 1999 and through December 31, 2003, the closing price of its common stock has ranged from a low of $0.10 per share to a high of $39.00 per share, but its common stock has not traded above $0.68 per share during 2003. Announcements by us or others regarding the receipt of customer orders, quarterly variations in operating results, acquisitions or divestitures, additional equity or debt financings, results of customer field trials, scientific discoveries, technological innovations, litigation, product developments, patent or proprietary rights, government regulation and general market conditions may have a significant impact on the market price of the common stock. In addition, fluctuations in the price of the Company’s common stock could affect the Company’s ability to maintain the listing of its common stock on the American Stock Exchange.

As of December 31, 2003, the Company had (i) outstanding warrants to purchase 10 million shares of common stock at a weighted average exercise price of $0.20 per share and (ii) outstanding options to purchase 6,659,557 shares of common stock at a weighted average exercise price of $0.55 per share (646,320 of which have not yet vested) issued to employees, directors and consultants pursuant to the 2003 Equity Incentive Plan and its predecessor 1993 Stock Option Plan as Amended, the merger agreement with Spectral Solutions, and individual agreements with management and directors. In order to attract and retain key personnel, the Company may issue additional securities, including stock options, in connection with the Company’s employee benefit plans, or may lower the price of existing stock options.

During February 2004, the warrant holders exercised all their warrants, resulting in 10 million shares of the Company’s common stock being issued. The Company received the $2 million aggregate strike price for the exercise of these warrants.

The exercise of options and warrants for common stock and the issuance of additional shares of common stock and/or rights to purchase common stock at prices below market value would be dilutive to existing stockholders and may have an adverse effect on the market value of the common stock.

At the time of this filing, officers, directors and principal stockholders (holding greater than 5% of outstanding shares) together control approximately 45% of the outstanding voting power. Consequently, these stockholders, if they act together, would be able to exert significant influence over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. In addition, this concentration of ownership may delay or prevent a change of control of the Company, even if a change may be in the best interests of the Company’s stockholders. The interests of these stockholders may not always coincide with the interests of the Company’s or the interests of other stockholders. Accordingly, these stockholders could cause the Company to enter into transactions or agreements that it would not otherwise consider.

There exist certain arrangements which may be deemed to have a potential “anti-takeover” effect in that such provisions may delay, defer or prevent a change of control of the Company. In February 1996, the Board of Directors adopted a stockholders rights plan. In addition, the Company’s Certificate of Incorporation and By-Laws provide that (i) the Board of Directors has authority to issue series of the Company’s preferred stock with such voting rights and other powers as the Board of Directors may determine; (ii) prior specified notice must be given by a stockholder making nominations to the Board of Directors or raising business matters at stockholders meetings; and (iii) the Board of Directors is divided into three classes, each serving for staggered three-year terms. The effect of the rights plan and the anti-takeover provisions in charter documents may be to deter business combination transactions not approved by the Company’s Board of Directors, including acquisitions that may offer a premium over market price to some or all stockholders.

The principal target market for the Company’s products is wireless telecommunications. The devotion of substantial resources to the wireless telecommunications market creates vulnerability to adverse changes in this market. Adverse developments in the wireless telecommunications market, which could come from a variety of sources, including future competition, new technologies or regulatory decisions, could affect the competitive position of wireless systems. Any adverse developments in the wireless telecommunications market may have a material adverse effect on the Company’s business, operating results and financial condition.

The Company is Dependent on the Enhancement of Existing 2G and 2.5G Networks and the Build-Out of 3G Networks, and the Capital Spending Patterns of Wireless Network Operators

Increased sales of products is dependent on a number of factors, one of which is the build-out of third generation, or 3G, enabled wireless communications networks as well as enhancements of existing infrastructure. Building wireless networks is capital intensive, as is the process of upgrading existing second generation, 2G, equipment. Further, the capital spending patterns of wireless network operators is beyond management’s control and depends on a variety of factors, including access to financing, the status of federal, local and foreign government regulation and deregulation, changing standards for wireless technology, the overall demand for wireless services, competitive pressures and general economic conditions. The build-out of 2.5G and 3G enabled networks may take years to complete. The magnitude and timing of capital spending by these operators for constructing, rebuilding or upgrading their systems significantly impacts the demand for the Company’s products. Any decrease or delay in capital spending patterns in the wireless communication industry, whether because of a general business slowdown or a reevaluation of the prospective demand for 2.5G and 3G services, would delay the build-out of these networks and may significantly harm business prospects.

The Company’s Success Depends on the Market’s Acceptance of its Products

The Company’s RF filter products, including its ANF and RF² products, have not been sold in very large quantities and a sufficient market may not develop for these products. Customers establish demanding specifications for performance, and although the Company believes it has met or exceeded these specifications to date, there is no guarantee that the wireless service providers will elect to use these solutions to solve their wireless network problems. Although the Company has received several orders from wireless operators for the Company’s products over the past year, there is no assurance that it will continue to receive orders from these customers.

Rapid Technological Change and Future Competitive Technologies Could Negatively Affect Operations

The field of telecommunications is characterized by rapidly advancing technology. The Company’s success will depend in large part upon its ability to keep pace with advancing its high performance RF filter technology and efficient, readily available low cost materials technologies. Rapid changes have occurred, and are likely to continue to occur, in the development of wireless telecommunications. Development efforts may be rendered obsolete by the adoption of alternative solutions to current wireless operator problems or by technological advances made by others.

Sales to three of the Company’s customers accounted for 98% and 95% of the Company’s total revenues for 2003 and 2002, respectively. In addition, a significant amount of the Company’s technical and managerial resources have been focused on working with these and a limited number of other operators and OEMs.

The Company expects that if its products achieve market acceptance, a limited number of wireless service providers and OEMs will account for a substantial portion of revenue during any period. Sales of many of the Company’s products depend in significant part upon the decision of prospective customers and current customers to adopt and expand their use of these products. Wireless service providers, wireless equipment OEMs and the Company’s other customers are significantly larger than, and are able to exert a high degree of influence over the Company. Customers’ orders are affected by a variety of factors such as new product introductions, regulatory approvals, end user demand for wireless services, customer budgeting cycles, inventory levels, customer integration requirements, competitive conditions and general economic conditions. The failure to attract new customers would have a material adverse effect on the business, operating results and financial condition.

Prior to selling products to customers, the Company may be required to undergo lengthy approval and purchase processes. Technical and business evaluation by potential customers can take up to a year or more for products based on new technologies. The length of the approval process is affected by a number of factors, including, among others, the complexity of the product involved, priorities of the customers, budgets and regulatory issues affecting customers. The Company may not obtain the necessary approvals or ensuing sales of such products may not occur. The length of customers’ approval process or delays could make the Company’s quarterly revenues and earnings inconsistent and difficult to trend.

Certain parts and components used in the Company’s RF filter products are only available from a limited number of sources. The Company’s reliance on these limited source suppliers exposes it to certain risks and uncertainties, including the possibility of a shortage or discontinuation of certain key components and reduced control over delivery schedules, manufacturing capabilities, quality and costs. Any reduced availability of such parts or components when required could materially impair the ability to manufacture and deliver products on a timely basis and result in the cancellation of orders, which could have a material adverse effect on the business, operating results and financial condition.

In addition, the purchase of certain key components involves long lead times and, in the event of unanticipated increases in demand for its products, the Company may be unable to manufacture products in quantities sufficient to meet customers’ demand in any particular period. The Company has few guaranteed supply arrangements with its limited source suppliers, does not maintain an extensive inventory of parts or components, and customarily purchases parts and components pursuant to actual or anticipated purchase orders placed from time to time in the ordinary course of business.

Related to this topic, the Company produces substantially all of its products through third-party contract manufacturers. Like raw materials, the elimination of any of these entities or delays in the fulfillment process, for whatever reason, may impact the Company’s ability to fulfill customer orders on a timely basis and may have a material adverse effect on the business, operating results, or financial condition.

To satisfy customer requirements, the Company may be required to stock certain long lead time parts and/or finished product, in anticipation of future orders or otherwise commit funds toward future purchase. The failure of such orders to materialize as forecasted could limit resources available for other important purposes or accelerate the requirement for additional funds. In addition, such excess inventory could become obsolete, which would adversely affect financial performance. Business disruption, production shortfalls or financial difficulties of a limited source supplier could materially and adversely affect the Company by increasing product costs or reducing or eliminating the availability of such parts or components. In such events, the inability to develop alternative sources of supply quickly and on a cost-effective basis could materially impair the ability to manufacture and deliver products on a timely basis and could have a material adverse effect on the business, operating results and financial condition.

The Company’s success will depend in large part upon its ability to attract and retain highly qualified management, engineering, manufacturing, marketing, sales and R&D personnel. Due to the specialized nature of the Company’s business, it may be difficult to locate and hire qualified personnel. The loss of services of one of the Company’s executive officers or other key personnel, or the failure to attract and retain other executive officers or key personnel, could have a material adverse effect on the business, operating results and financial condition.

Failure of Products to Perform Properly Might Result in Significant Warranty Expenses

In general, products carry a warranty of one or two years, limited to replacement of the product or refund of the cost of the product. In addition, the Company offers its customers extended warranties. Repeated or widespread quality problems could result in significant warranty expenses and/or the loss of customer confidence. The occurrence of such quality problems could have a material adverse effect on the business, operating results and financial condition.

Intense Competition, and Increasing Consolidation in the Company’s Industry, Could Create Stronger Competitors and Harm the Business

The wireless telecommunications equipment market is very competitive. Many of these companies have substantially greater financial resources, larger research and development staffs and greater manufacturing and marketing capabilities than the Company. Its products compete directly with products which embody existing and future competing commercial technologies. Other emerging wireless technologies, may also provide protection from RF interference and offer enhanced range to wireless communication service providers, potentially at lower prices and/or superior performance, and may therefore compete with the Company’s products. High performance RF filters may not become a preferred technology to address the needs of wireless communication service providers. Failure of its products to improve performance sufficiently, reliably, or at an acceptable price or to achieve commercial acceptance or otherwise compete with conventional and new technologies, will have a material adverse effect on the business, operating results and financial condition.

The Company’s success will depend in part on its ability to obtain patent protection for its products and processes, to preserve trade secrets and to operate without infringing upon the patent or other proprietary rights of others and without breaching or otherwise losing rights in the technology licenses upon which any of the Company’s products are based. As of December 31, 2003, the Company had been issued or was actively pursuing applications for more than 100 US and foreign patents. The Company acquired patent rights in connection with the purchase of the Adaptive Notch Filtering business unit of Lockheed Martin Canada. One of the patents is jointly owned with Lucent Technologies, Inc. The claims in those patents often appear to overlap and there have been interference proceedings pending in the United States Patent and Trademark Office (not currently involving the Company) regarding rights to inventions claimed in certain patent applications. The Company believes there are a large number of patents and patent applications covering RF filter products and other products and technologies that it is pursuing. Accordingly, the patent positions of companies using RF technologies, including the Company, are uncertain and involve complex legal and factual questions. The patent applications filed by the Company or others may not result in issued patents or the scope and breadth of any claims allowed in any patents issued to the Company or others may not exclude competitors or provide competitive advantages. In addition, patents issued to the Company, its subsidiaries or others may not be held valid if subsequently challenged or others may claim rights in the patents and other proprietary technologies owned or licensed by the Company. Others may have developed or may in the future develop similar products or technologies without violating any of the Company’s proprietary rights. Furthermore, the loss of any license to technology that the Company might acquire in the future may have a material adverse effect on the business, operating results and financial condition.

Some of the patents and patent applications owned by us are subject to non-exclusive, royalty-free licenses held by various U.S. governmental units. These licenses permit these U.S. government units to select vendors other than us to produce products for the U.S. Government, which would otherwise infringe the Company’s patent rights that are subject to the royalty-free licenses. In addition, the U.S. Government has the right to require us to grant licenses (including exclusive licenses) under such patents and patent applications or other inventions to third parties in certain instances.

Older patent applications in the U.S. are currently maintained in secrecy until patents are issued. In foreign countries and for newer U.S. patent applications, this secrecy is maintained for a period of time after filing. Accordingly, publication of discoveries in the scientific literature or of patents themselves or laying open of patent applications in foreign countries or for newer U.S. patent applications tends to lag behind actual discoveries and filing of related patent applications. Due to this factor and the large number of patents and patent applications related to RF materials and technologies, and other products and technologies that the Company is pursuing, comprehensive patent searches and analyses associated with HTS materials, RF technologies and other products and technologies that the Company is pursuing are often impractical or not cost-effective. As a result, patent and literature searches cannot fully evaluate the patentability of the claims in its patent applications or whether materials or processes used by the Company for its planned products infringe or will infringe upon existing technologies described in U.S. patents or may infringe upon claims in patent applications made available in the future. Because of the volume of patents issued and patent applications filed relating to RF technologies and other products and technologies that it is pursuing, the Company believes there is a significant risk that current and potential competitors and other third-parties have filed or will file patent applications for, or have obtained or will obtain, patents or other proprietary rights relating to materials, products or processes used or proposed to be used by the Company. In any such case, to avoid infringement, it would have to either license such technologies or design around any such patents. The Company may be unable to obtain licenses to such technologies or, if obtainable, such licenses may not be available on terms acceptable to the Company or the Company may be unable to successfully design around these third-party patents.

Participation in litigation or patent office proceedings in the U.S. or other countries, which could result in substantial cost to and diversion of effort by the Company, may be necessary to enforce patents issued or licensed to it, to defend itself against infringement claims made by others or to determine the ownership, scope or validity of the proprietary rights of the Company and others. The parties to such litigation may be larger, better capitalized than the Company and better able to support the cost of litigation. An adverse outcome in any such proceedings could subject the Company to significant liabilities to third parties, require it to seek licenses from third parties and/or require it to cease using certain technologies, any of which could have a material adverse effect on the business, operating results and financial condition.

The Company has been subject to a number of lawsuits and currently has ongoing legal proceedings involving the Company’s assertion of patent infringement litigation and related counterclaims raised by the defense. If the Company is not successful in defending itself against these counterclaims, there may be a material and adverse effect on the Company’s business, operating results and financial condition. The Company has announced the settlement of the Laves litigation as described elsewhere.

Although the Company believes that its wireless telecommunications products themselves would not be subject to licensing by, or approval requirements of, the FCC, the operation of base stations is subject to FCC licensing and the radio equipment into which the Company’s products would be incorporated is subject to FCC approval. Base stations and the equipment marketed for use therein must meet specified technical standards. The ability to sell the Company’s wireless telecommunications products is dependent on the ability of wireless base station equipment manufacturers and wireless base station operators to obtain and retain the necessary FCC approvals and licenses. In order for them to be acceptable to base station equipment manufacturers and to base station operators, the characteristics, quality and reliability of the Company’s base station products must enable them to meet FCC technical standards. The Company may be subject to similar regulations of the Canadian federal and provincial governments. Any failure to meet such standards or delays by base station equipment manufacturers and wireless base station operators in obtaining the necessary approvals or licenses could have a material adverse effect on the business, operating results and financial condition. In addition, HTS RF filters are on the U.S. Department of Commerce’s export regulation list. Therefore, exportation of such RF filters to certain countries may be restricted or subject to export licenses.

The Company is subject to governmental labor, safety and discrimination laws and regulations with substantial penalties for violations. In addition, employees and others may bring suit against it for perceived violations of such laws and regulations. Defense against such complaints could result in significant legal costs for us. Although the Company endeavors to comply with all applicable laws and regulations, it may be the subject of complaints in the future, which could have a material adverse effect on the business, operating results and financial condition.

Certain hazardous materials may be used in research, development and manufacturing operations. As a result, the Company is subject to stringent federal, state and local regulations governing the storage, use and disposal of such materials. It is possible that current or future laws and regulations could require it to make substantial expenditures for preventive or remedial action, reduction of chemical exposure, or waste treatment or disposal. The Company believes it is in material compliance with all environmental regulations and to date has not had to incur significant expenditures for preventive or remedial action with respect to the use of hazardous materials. However, its operations, business or assets could be materially and adversely affected by the interpretation and enforcement of current or future environmental laws and regulations. In addition, although the Company believes that its safety procedures for handling and disposing of such materials comply with the standards prescribed by state and federal regulations, there is the risk of accidental contamination or injury from these materials. In the event of an accident, the Company could be held liable for any damages that result. Furthermore, the use and disposal of hazardous materials involves the risk that the Company could incur substantial expenditures for such preventive or remedial actions. The liability in the event of an accident or the costs of such actions could exceed available resources or otherwise have a material adverse effect on the business, results of operations and financial condition. The Company carries property and workman’s compensation insurances in full force and effect through nationally known carriers which include pollution cleanup or removal and medical claims for industrial incidents.

In the future, the Company may pursue acquisitions to obtain products, services and technologies that it believes will complement or enhance its current product or services offerings. At present, no agreements or other arrangements exist with respect to any such acquisition. An acquisition may not produce the revenue, earnings or business synergies as anticipated and may attach significant unforeseen liabilities, and an acquired product, service or technology might not perform as expected. If an acquisition is pursued, the Company’s management could spend a significant amount of time and effort in identifying and completing the acquisition and may be distracted from the operations of the business. In addition, management would probably have to devote a significant amount of resources toward integrating the acquired business with the existing business, and that integration may not be successful.

The Company is in discussions and has agreements in place with companies in non-U.S. markets to form manufacturing, product development joint ventures and other marketing, distribution or consulting arrangements.

The Company believes that non-U.S. markets could provide a substantial source of revenue in the future. However, there are certain risks applicable to doing business in foreign markets that are not applicable to companies doing business solely in the U.S. For example, the Company may be subject to risks related to fluctuations in the exchange rate between the U.S. dollar and foreign currencies in countries in which it does business. In addition, it may be subject to the additional laws and regulations of these foreign jurisdictions, some of which might be substantially more restrictive than similar U.S. ones. Foreign jurisdictions may also provide less patent protection than is available in the U.S., and the Company may be less able to protect its intellectual property from misappropriation and infringement in these foreign markets.

The Company maintains its corporate headquarters in a 35,000 square foot building located in Mt. Prospect, Illinois under a lease which expires in October 2004. Additionally, it maintains a 6,500 square foot facility located in North York, Ontario under a sublease that expires in August 2004, which has been further broken into two segments which have subsequently been subleased to other entities. The Company also has a small office lease in Dallas, Texas (expiring February 2005). The Mount Prospect facility houses the Company’s manufacturing, research, development, engineering and marketing activities. The Company believes that this facility is adequate and suitable for its current needs and that additional space would be available on commercial terms as necessary to meet any future needs. As the Company currently outsources manufacturing for its products, it expects to move into a new facility by October 2004.

In July 2001, the Company filed suit in the United States District Court for the District of Delaware against Conductus, Inc. and Superconductor Technologies, Inc. alleging infringement of U.S. Patent No. 6,263,215, entitled “Cryoelectronically Cooled Receiver Front End for Mobile Radio Systems” (“the ‘215 patent”). This suit alleges that Conductus’ and Superconductor Technologies’ base station front-end systems containing cryogenically cooled superconducting filters infringe this patent. The Company seeks a permanent injunction enjoining Conductus and Superconductor Technologies from marketing, selling or manufacturing these products, as well as triple damages and attorneys fees. Conductus and Superconductor Technologies denied these allegations and asked the court to enter a judgment that the patent is invalid and not infringed. Conductus and Superconductor Technologies also asserted the defense of inequitable conduct and a counterclaim for a declaration that the patent is unenforceable as well as federal and state law counterclaims, including claims of unfair competition. Conductus and Superconductor Technologies sought both compensatory and punitive damages as well as attorneys fees and costs.

No. 6,205,340 B1 entitled “Cryoelectronic Receiver Front End For Mobile Radio Systems”. On April 17, 2002, the court dismissed these (the Company’s) counterclaims without prejudice to the Company’s right to assert these counterclaims in a separate action.

On February 10, 2003, the court disposed of various motions for summary judgment filed by each party. The court denied Superconductor Technologies’ motion for summary judgment of invalidity of the ‘215 patent as well as Conductus’ motion for summary judgment limiting computation of damages to a reasonable royalty for sales to Dobson Communications, Inc. On Superconductor Technologies’ motion for summary judgment of non-infringement, the court granted the motion with respect to claim 13 of the ‘215 patent and otherwise denied the motion with respect to each of the other asserted claims. With regard to Conductus’ motion for summary judgment of non-infringement, the court granted the motion with respect to claim 13 of the ‘215 patent and otherwise denied the motion with respect to each of the other asserted claims. In addition, the court denied Conductus’ motion for summary judgment of invalidity of all asserted claims for causes of action existing prior to the date of issuance of the certificate of correction and of invalidity of claim 13. The court also denied the Company’s motions for summary judgment that Superconductor Technologies’ internal projects are not prior art to the ‘215 patent and to dismiss the defendants’ counterclaims alleging unfair competition and interference with business relations.

On April 3, 2003, the jury returned with its verdict. The jury rejected the Company’s positions and determined its patent to be invalid. Additionally, the jury determined that inequitable conduct had occurred and subsequently awarded defendants $3.87 million in damages from the Company. The Company was severely disappointed by this verdict and it engaged in the post-trial motion process to overturn it. On August 21, 2003, the court issued its ruling on the post-trial motions. The court overturned the jury’s determination of unfair competition on the part of the Company and denied all requests for damages, including the $3.87 million jury award cited above. The court did not, however, overturn the jury determinations of patent invalidity and unenforceability based on inequitable conduct and denied ISCO’s motion for a new trial.

During September 2003, the Company filed an appeal of this verdict requesting the reinstatement of its patent and the rights inherent within that patent, and Superconductor Technologies, Inc. filed a cross-appeal requesting reinstatement of the jury award and attorney’s fees.

The Company intends to continue to prosecute its claims vigorously on appeal and continue to defend against defendants’ counterclaims. The Company believes the patent to be valid, the counterclaims asserted against the Company to be without merit, and that it is in the best interests of the Company and its shareholders to pursue this matter vigorously.

In November 2001, the Company filed suit against Dobson Communications, Inc. for allegedly infringing this patent. The action has been stayed, per agreement between the parties, until resolution of the matter between the Company and Conductus and Superconductor Technologies. The parties have agreed that Dobson Communications will be bound by any and all final, non-appealable determinations, holdings or findings with respect to all liability issues in the Company’s case against Conductus.

On July 17, 2000 former President and CEO Edward W. Laves filed a two-count Complaint (the “Complaint”) in the Law Division of the Circuit Court of Cook County, Illinois. Laves named as Defendants the Company and three directors and sued for breach of contract (Count I) and for violation of the Illinois Wage Payment and Collection Act (“Wage Act”) (Count II). Laves claimed the Defendants constructively terminated him and then failed to pay severance benefits under his employment agreement. On April 8, 2002, Laves was given leave to amend his Complaint and add Count III against the individual director Defendants for tortious interference with contractual obligations. According the Complaint, Laves sought damages against the company in an amount estimated to exceed $12 million, plus attorney’s fees under the Wage Act and pre-and post-judgment interest. He sought the same damages against the individual director Defendants, plus $5,000,000 for punitive damages.

During February 2004, the parties reached settlement. Laves was paid $700,000, half of which came from the Company and the remainder from the Company’s insurance carrier, and all parties agreed to terminate proceedings, with prejudice. The Company accrued for its portion as a contingent liability as of December 31, 2003.

At our annual meeting of shareholders held on December 15, 2003, the following proposals were approved by the margins indicated:

Item 5. Market for Registrant’s Common Equity and Related Stockholder Matters

The Common Stock has been quoted since June 2002 on the American Stock Exchange under the symbol “ISO.” Prior to that, and until April 1999, the stock had been quoted on the OTC Bulletin Board under the symbol “ISCO.” From 1993 until April 1999, the Common Stock was quoted on the NASDAQ National Market. The following table shows, for the periods indicated, the reported high and low sale prices for the Common Stock. Such prices reflect prices between dealers, without retail mark up, mark down, or commissions and may or may not reflect actual transactions.

On December 31, 2003, there were approximately 300 holders of record of the Common Stock. On such date the closing bid price for the Company’s common stock as reported on the American Stock Exchange was $0.55.

The Company has never paid cash dividends on the Common Stock and the Company does not expect to pay any dividends on its Common Stock in the foreseeable future.

During the three months ended December 31, 2003, we issued a total of 1,000,000 shares of our common stock that were not registered under the Securities Act of 1933, as amended (“1933 Act”) in reliance on an exemption pursuant to Section 4(2) of the 1933 Act. These shares of common stock were issued pursuant to a Settlement Agreement and Release with Morgan and Finnegan L.L.P. (“M&F”), the Company’s former patent counsel. The agreement reflected the resolution of a dispute between the Company and M&F and the shares were issued in consideration for the release of claims by M&F against the Company.

The following table presents selected consolidated financial data with respect to the Company as of and for the years ended December 31, 1999, 2000, 2001, 2002 and 2003. The selected consolidated financial data for each of the years in the five-year period ended December 31, 2003 have been derived from the audited consolidated financial statements of the Company. The information set forth below should be read in conjunction with Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Item 8. “Financial Statements and Supplementary Data.”

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The discussion below contains certain forward looking statements that reflect our current expectations regarding the Company’s future results of operations, performance and achievements. Please see the discussion of such forward looking statements under “Forward Looking Statements” in Item 1 above.

The Company has shifted from manufacturing in-house to an outsourced manufacturing model. Its products are designed for efficient production in this manner, emphasizing solid-state electronics over mechanical devices with moving parts. The decrease in

cost associated with these developments, coupled with enhanced product functionality, has allowed the Company to realize improved

margins. Extensions of developed technology, based on substantial input from customers, have allowed the Company to launch the RF² product and consider additional solutions while controlling total R&D cost. The Company has announced several recent events, both during 2003 and early 2004, such as the resolution of the Laves litigation, the resolution of a vendor dispute reserved at $2 million in exchange for 1 million shares of the Company’s common stock, the receipt of $2 million from the exercise of all outstanding warrants (which were related to the credit line), and the extension of its credit line debt maturity date from March and October 2004 to April 2005. Despite these improvements, the wireless telecommunications industry is subject to risks beyond the Company’s control that can negatively impact customer capital spending budgets (as occurred during 2003) and/or spending patterns. For this and other reasons, the Company’s financial statements have been prepared assuming the Company will continue as a going concern.

The Company’s net sales decreased $425,000, or 12%, from $3,663,000 in 2002 to $3,238,000 in 2003, as a result of a focus on more profitable business and due to an industry-wide reduction in capital expenditures during the first half of 2003. Sales of the Company’s HTS products were substantially reduced, while revenues from its ANF products increased and revenues began to be realized on its RF² products during the fourth quarter 2003, shortly after the September 2003 product launch. The Company anticipates its net sales to increase during 2004 based on existing and/or anticipated customer orders.

Cost of products sold decreased $1,925,000, or 54% from $3,565,000 in 2002 to $1,640,000 in 2003. This occurred despite only a 12% decrease in revenue, as a result of various cost control measures adopted during the preceding two years, including the continued emphasis on outsourcing manufacturing processes and the focus on profitable business, and the nature and value of products sold (i.e., the reduced sales of HTS products and increased sales of ANF and RF² products). The cost of products sold for 2003 and 2002 consisted of direct material, labor and overhead costs associated with the products that were shipped during the period, as well as other costs consisting primarily of allocated overhead costs incurred to produce units in ending finished goods inventory that exceed net realizable value. The Company expects the cost of products sold as a percentage of revenue to improve during 2004 due to anticipated revenue increases and related efficiencies, certain cost control initiatives, and primarily due to the continued emphasis on outsourcing the manufacture of its products.

The Company’s internally funded research and development expenses decreased by $1,749,000, or 64%, from $2,737,000 in 2002 to $988,000 during 2003. These reductions were primarily due to cost-cutting measures and the shift from initial development to product improvement and related product expansion as the focus of development efforts. The emphasis on new products with a greater probability of profitable near-term commercial sales also were significant in this reduction. The Company expects these expenses to remain at approximately the 2003 level.

Selling and marketing expenses decreased $1,241,000, or 56%, from $2,201,000 during 2002 to $960,000 during 2003. This decrease was due to cost reductions implemented during the past year. The Company expects these expenses during 2004 to be at or above the 2003 level.

General and administrative expenses decreased $2,709,000, or 34%, from $7,973,000 in 2002 to $5,264,000 during 2003. This decrease was due to the reduction in expenses in the patent litigation as described elsewhere in this report, which more than offset an increase in non-cash employee compensation. The Company expects general and administrative expenses to decrease further during 2004 due to reduced litigation expenses.

Interest income decreased $58,000, or 92%, from $63,000 in 2002 to $5,000 during 2003. This decrease was due to the timing of the credit line (October 2002). The Company became infused with cash during February 2002 after its Shareholder Rights Offering, increasing interest income during 2002. While operating under its uncommitted line of credit from October 2002 and beyond, the Company has not maintained, and does not expect to maintain, significant amounts of cash on which interest may be earned.

Interest and warrant expense increased $870,000, or 266%, from $327,000 in 2002 to $1,197,000 during 2003. During February 2002, shareholder notes of $9,425,000, plus accrued interest, were repaid following the Shareholder Rights Offering, both of which are described elsewhere in this document. The Company borrowed $2 million during the fourth quarter of 2002 under an uncommitted line of credit with entities affiliated with its two largest shareholders. The Company borrowed an additional $3 million under this line and a related supplement during 2003. As a result of the borrowings on this line, 10 million warrants were issued. The interest expense recorded during 2003 includes $862,000 of non-cash expense related to these warrants.

An “other expense” of $350,000 was accrued as of December 31, 2003 as a contingent liability for the Laves litigation settlement. This settlement was negotiated and entered into during February 2004.

The Company’s net sales increased $1,682,000, or 85%, from $1,981,000 in 2001 to $3,663,000 in 2002, as a result of higher unit volume of the Company’s radio frequency (“RF”) front-end products. This increase was due to stronger sales volume for its ANF^™ product.

Cost of products sold decreased $413,000, or 10% from $3,978,000 in 2001 to $3,565,000 in 2002. This occurred despite an 85% increase in revenue as a result of various cost control measures adopted during the preceding 15 months and the continued emphasis on outsourcing manufacturing processes. The cost of products sold for 2002 and 2001 consisted of direct material, labor and overhead costs associated with the products that were shipped during the period, as well as other costs consisting primarily of allocated overhead costs incurred to produce units in ending finished goods inventory that exceed net realizable value. Due to low utilization levels and excess capacity in the Company’s manufacturing facility, cost of products sold exceeded net sales for 2001 and nearly did so for 2002.

The Company’s internally funded research and development expenses decreased by $4,395,000, or 62%, from $7,132,000 in 2001 to $2,737,000 during 2002. These reductions were primarily due to cost-cutting measures, including the consolidation of the Colorado and Canadian operations into the Illinois facility. The shift from initial development to product improvement as the focus of development efforts on products with a greater probability of commercial sales also were significant in this reduction.

Selling and marketing expenses decreased $1,063,000, or 33%, from $3,264,000 during 2001 to $2,201,000 during 2002. This decrease was due to cost reductions implemented during that year.

General and administrative expenses increased $235,000, or 3%, from $7,738,000 in 2001 to $7,973,000 during 2002. This increase was due to the expenses in the patent litigation as described elsewhere in this report, which were $1.9 million higher during 2002 than they were during 2001 as the case approached the March 2003 trial date. If not for this line item, total general and administrative expenses would have decreased by $1.6 million, or 21%.

Interest income decreased $76,000, or 55%, from $139,000 in 2001 to $63,000 during 2002. This decrease was due, in part, to the timing and magnitude of funding and the vehicles employed. While operating under its uncommitted line of credit, the Company did not expect to maintain significant amounts of cash on which interest may be earned.

Interest expense increased $97,000, or 42%, from $230,000 in 2001 to $327,000 during 2002. During February 2002, shareholder notes of $9,425,000, plus accrued interest, were repaid following the Shareholder Rights Offering. The Company borrowed $2 million during the fourth quarter of 2002 under an uncommitted line of credit with entities affiliated with its two largest shareholders. As a result of the borrowings on this line, warrants were issued. The interest expense recorded during 2002 included $128,000 of non-cash expense related to these warrants.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 3 to the financial statements, the Company incurred a net loss of $7,156,000 during the year ended December 31, 2003, and, as of that date, the Company’s accumulated deficit is $150,096,000. In addition, the Company has consistently used, rather than provided, cash in its operations. These factors, among others, as discussed in Note 3 to the financial statements, raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 3. The financial statements do not include any adjustments, including any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification of liabilities that might result from the outcome of this uncertainty.

At December 31, 2003, the Company’s cash and cash equivalents, excluding restricted certificates of deposit, were $346,000, an increase of $130,000 from the December 31, 2002 balance of $216,000. Subsequent to the reporting date, the Company received $2 million from the exercise of all outstanding warrants and paid its portion of the Laves settlement ($350,000).

The continuing development of and expansion in sales of the Company’s RF product lines, as well as the continued defense of its intellectual property, may require a commitment of funds to undertake product line development and potentially the expansion of manufacturing capabilities and to market and sell its RF front-end products. The actual amount of the Company’s future funding requirements will depend on many factors, including: the amount and timing of future revenues, the level of product marketing and sales efforts to support the Company’s commercialization plans, the magnitude of its research and product development programs, the ability of the Company to improve or maintain product margins, the potential cost of additional plant and equipment for manufacturing and the costs involved in protecting the Company’s patents or other intellectual property.

As of the date of this filing, the Company believes that it has sufficient funds to operate its business as identified herein without the need for substantial future capital sources during 2004, provided that the Company is able to borrow the $1 million remaining under the uncommitted line of credit. Should this credit become unavailable, the Company believes it has sufficient funds to operate until the third or fourth quarter of 2004, and quite possibly longer, subject to operating results. The Company intends to look into augmenting its existing capital position by utilizing the credit line as identified and through other sources of capital.

During December 2003, the Company and Morgan and Finnegan L.L.P. (“M&F”) entered into a Settlement Agreement and Release. The agreement reflected the resolution of a dispute between the Company and M&F, the Company’s former patent counsel. The Company had reserved a two million dollar ($2,000,000) accrued liability related to the dispute. This accrued liability is resolved and no longer necessary due to the resolution of the dispute pursuant to which the Company has issued 1,000,000 shares of common stock to M&F. Both the expense that created the accounting reserve and the reversal of that expense upon termination of the reserve occurred during the fiscal year 2003.

As of the reporting date, the Company had drawn $5 million of debt financing under a credit line, as described below. During October 2002, the Company entered into an Uncommitted Line of Credit with its two largest shareholders, an affiliate of Elliott Associates, L.P. (Manchester Securities Corporation) and Alexander Finance, L.P. This line provided up to $4 million to the Company. This line was uncommitted, such that each new borrowing under the facility would be subject to the approval of the lenders. Borrowings on this line bore an interest rate of 9.5% and are collateralized by all the assets of the Company. Outstanding loans under this agreement would be required to be repaid on a priority basis should the Company receive new funding from other sources. Additionally, the lenders were entitled to receive warrants to the extent funds were drawn down on the line. The warrants bore a strike price of $0.20 per share of common stock and were to expire on April 15, 2004. The credit line was to mature and be due, including accrued interest thereon, on March 31, 2004. Due to an agreement between the parties that did not provide warrants with respect to the most recent $2 million in borrowings, a maximum of 10 million warrants were issued as a result of this transaction. During February 2004, the warrant holders exercised all of their warrants, contributing $2 million to the Company in exchange for 10 million shares of common stock.

According to existing accounting pronouncements and SEC guidelines, the Company has allocated the proceeds of these borrowings between their debt and equity components. As a result of these borrowings during 2002, the Company will record a non-cash charge of $1.2 million through the outstanding term of the warrants (April, 2004). $217,000 and $862,000 of that amount were recorded during the fourth quarter and full year 2003, respectively.

As announced during October 2003, the Company entered into an agreement with its lenders to supplement the credit line with an additional $2 million, $1 million of which was drawn immediately and $1 million available to be drawn upon the Company’s request and subject to the approval of the lenders. This supplemental facility bore a 14% rate of interest and was due October 31, 2004. Unlike the previous credit line, the supplemental facility did not include any stock warrants. The term of the previous credit line were not affected by this supplement, and as such the $4 million borrowed under that line, plus accrued interest, remained due March 31, 2004.

During February 2004, these credit lines were extended to a due date of April 2005, with interest after the initial periods to be charged at 14%. No warrants or other inducements were issued with respect to these extensions. Additionally, lenders exercised their 10 million warrants during February 2004, agreeing to let the Company use the funds for general purposes as opposed to repaying debt.

After the events listed above, particularly the events subsequent to the reporting date including the debt restructuring (during February 2004), the Company’s current liabilities no longer exceeded its cash and current assets.

The discussion and analysis of the Company’s financial condition and results of operations are based upon the Company’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amount of assets and liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the Company’s financial statements. Actual results may differ from these estimates under different assumptions or conditions.

Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties, and potentially result in materially different results under different assumptions and conditions. The Company believes that its critical accounting policies are limited to those described below. For a detailed discussion on the application of these and other accounting policies, see Note 2 in the notes to the consolidated financial statements.

Revenues from product sales are generally recognized at the time of shipment and are recorded net of estimated returns and allowances. Revenues from services are generally recognized upon substantial completion of the service and acceptance by customer. The Company has, under certain conditions, granted customers the right to return product during a specified period of time after shipment. In these situations, the Company establishes a liability for estimated returns and allowances at the time of shipment and makes the appropriate adjustment in revenue recognized for accounting purposes. During the current year, no revenue was recognized on products that included a right to return at some future date. The Company has established a program which, in certain situations, allows customers or prospective customers to field test the Company’s products for a specified period of time. Revenues from field test arrangements are recognized upon customer acceptance of the products. The Company warrants its products against defects in materials and workmanship typically for a 1-2 year period from the date of shipment, though these terms may be negotiated on a case by case basis. A provision for estimated future costs related to warranty expenses is recorded when revenues are recognized. At December 31, 2003 and 2002, respectively, the Company has accrued $100,000 and $63,000 for warranty costs. Returns and allowances were not significant in any period reported.

On July 20, 2001, the FASB issued Statement of Financial Accounting Standards No. 141 (“SFAS No. 141”), “Business Combinations”, and Statement of Financial Accounting Standards No. 142 (“SFAS No. 142”), “Goodwill and Other Intangible Assets.” SFAS No. 141 is effective for all business combinations completed after June 30, 2001. SFAS No. 142 is effective for fiscal years beginning after December 15, 2001; however, certain provisions of such Statement apply to goodwill and other intangible assets acquired between July 1, 2001, and the effective date of SFAS No. 142. Major provisions of these Statements and their effective dates for the Company are as follows:

1. All business combinations initiated after June 30, 2001 must use the purchase method of accounting. The pooling of interest method of accounting is prohibited except for transactions initiated before July 1, 2001.

2. Intangible assets acquired in a business combination must be recorded separately from goodwill if they arise from contractual or other legal rights or are separable from the acquired entity and can be sold, transferred, licensed, rented, or exchanged, either individually or as a part of a related contract, assets, or liability.

3. Goodwill, as well as intangible assets with indefinite lives, acquired after June 30, 2001, will not be amortized. Effective January 1, 2002, all previously recognized goodwill and intangible assets with indefinite lives will no longer be subject to amortization.

4. Effective January 1, 2002, goodwill and intangible assets with indefinite lives will be tested for impairment annually and whenever there is an impairment indicator.

5. All acquired goodwill must be assigned to reporting units for purposes of impairment testing and segment reporting.

As of the reporting date, the Company had recorded unamortized goodwill assets resulting from the acquisitions of Spectral Solutions, Inc. and the Adaptive Notch Filter (ANF) division of Lockheed Martin Canada, Inc. during 2000. Beginning January 1, 2002, goodwill is no longer to be amortized but rather to be tested for impairment on an annual basis and between annual tests whenever there is an indication of potential impairment. Impairment losses would be recognized whenever the implied fair value of goodwill is determined to be less than its carrying value. During October of 2003, the Company completed the process of evaluating goodwill for impairment under SFAS No. 142. As the fair value, using quoted market prices for the Company’s common stock, exceeded the carrying amount, the goodwill was determined to be not impaired. There were no material adjustments relating to the classification of the Company’s intangible assets as a result of adopting SFAS No. 142.

Prior to the 2002 effective date of this standard, acquired goodwill from the two acquisitions completed during 2000 had been amortized using the straight-line method over eight years. The excess of cost over net assets acquired associated with assets acquired in a purchase business combination is included in impairment evaluations when events and circumstances may indicate impairment, management evaluated the recoverability of acquired goodwill by comparing the carrying value of the asset to the associated current and projected annual sales, operating profit, undiscounted annual cash flows and market value; management also considered business prospects, market trends and other economic factors in performing this evaluation. Based on this evaluation, there was no unrecorded permanent impairment related to acquired goodwill at December 31, 2001.

An allowance for doubtful receivables is maintained for potential credit losses. Management specifically analyzes accounts receivable, on a client by client basis, when evaluating the adequacy of our allowance for doubtful receivables including customer credit worthiness and current economic trends and records any necessary bad debt expense based on the best estimate of the facts known to date. Should the facts regarding the collectability of receivables change, the resulting change in the allowance would be charged or credited to income in the period such determination is made. Such a change could materially impact our financial position and results of operations.

The Company accounts for stock-based compensation using the intrinsic value method prescribed in Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations. Compensation costs for employee stock options is measured as the excess, if any, of the quoted market price of the Company’s common stock at the date of grant over the amount an employee must pay to acquire the stock.

No such arrangements existed as of December 31, 2003, except for leases as described and the minimum lease payments as detailed in this document.

We have audited the accompanying consolidated balance sheets of ISCO International, Inc. (a Delaware corporation) and subsidiaries, as of December 31, 2003 and 2002, and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the three years ended December 31, 2003. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of ISCO International, Inc. and subsidiaries as of December 31, 2003, 2002 and 2001, and the consolidated results of their operations and their cash flows for the three years ended December 31, 2003, in conformity with accounting principles generally accepted in the United States of America.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 3, the Company incurred a net loss of $7,156,075 during the year ended December 31, 2003, and, as of that date, the Company’s accumulated deficit is $150,096,105. In addition, the Company has consistently used, rather than provided, cash in its operations. These factors, among others, as discussed in Note 3 to the financial statements, raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 3. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

See the accompanying Notes which are an integral part of the financial statements.

ISCO International and its subsidiaries, Spectral Solutions, Inc., and Illinois Superconductor Canada Corporation, (the “Company”) address reverse link optimization issues, including interference issues, within wireless communications. The Company uses unique products, including ANF (Adaptive Notch Filters), RF², and other solutions, as well as service expertise, in improving the reverse link of a wireless system (the signal from the mobile device to the base station). A subset of this function is mitigating the impact of interference on wireless communications systems. These solutions are designed to enhance the quality, capacity, coverage and flexibility of wireless telecommunications services. The Company has historically marketed its products to cellular, PCS and wireless telecommunications service providers and OEM’s located both in the United States and in international markets.

Cash and cash equivalents consist of demand deposits, time deposits, money market funds, and commercial paper which have original maturities of three months or less from the date of purchase. Management believes that the financial institutions in which it maintains such deposits are financially sound and, accordingly, minimal credit risk exists with respect to these deposits.

The majority of the Company’s accounts receivable are due from companies in the telecommunications industry. Credit is extended based on evaluation of a customers’ financial condition and, generally, collateral is not required. Accounts receivable are due within 30 days and are stated at amounts due from customers, net of an allowance for doubtful accounts. Accounts outstanding longer than the contractual payment terms are considered past due. The Company determines its allowance by considering a number of factors, including the length of time trade accounts receivable are past due, the Company’s previous loss history, the customer’s current ability to pay its obligation to the Company, and the condition of the general economy and the industry as a whole. The Company writes-off accounts receivable when they become uncollectible, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts.

The Company establishes a reserve for customer accounts receivable balances that are potentially uncollectible. The reserve could be materially different if economic conditions change or actual results deviate from historical trends.

Inventories are stated at the lower of cost (determined on a first in, first out basis) or market.

Patents and trademarks represent costs, primarily legal fees and expenses, incurred in order to prepare and file patent applications related to various aspects of the Company’s technology and to its current and proposed products. Patents and trademarks are recorded at cost and are amortized using the straight-line method over the shorter of their estimated useful lives or 17 years. The recoverability of the carrying values of patents and trademarks is evaluated on an ongoing basis. During 2003 and 2002, the Company wrote off no patent-related costs. Total capitalized patent and trademark costs are $1,096,000 and $1,057,000 at December 31, 2003 and 2002, respectively. Capitalized patent costs related to pending patents are $669,000 and $595,000 at December 31, 2003 and 2002, respectively. Patents and trademarks are net of accumulated amortization of $172,000 and $133,000 at December 31, 2003 and 2002, respectively.

Property and equipment are stated at cost, less accumulated depreciation, and are depreciated over the estimated useful lives of the assets using accelerated methods. Leasehold improvements are amortized using the straight-line method over the shorter of the useful life of the asset or the term of the lease. Amortization of leasehold improvements is included in depreciation expense. The useful lives assigned to property and equipment for the purpose of computing book depreciation are as follows:

Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

Revenues from product sales are generally recognized at the time of shipment and are recorded net of estimated returns and allowances. Revenues from services are generally recognized upon substantial completion of the service and acceptance by customer. The Company has, under certain conditions, granted customers the right to return product during a specified period of time after shipment. In these situations, the Company establishes a liability for estimated returns and allowances at the time of shipment and makes the appropriate adjustment in revenue recognized for accounting purposes. During the current year, no revenue was recognized on products that included a right to return at some future date. The Company has established a program which, in certain situations, allows customers or prospective customers to field test the Company’s products for a specified period of time. Revenues from field test arrangements are recognized upon customer acceptance of the products. The Company warrants its products against defects in materials and workmanship typically for 1-2 years from the date of shipment, though these terms can be negotiated on a case by case basis. A provision for estimated future costs related to warranty expenses is recorded when revenues are recognized. At December 31, 2003 and 2002, respectively, the Company has accrued $100,000 and $63,000 for warranty costs. Returns and allowances were not significant in any period reported.

Sales to three of the Company’s customers accounted for 98% and 95% of the Company’s total sales for 2003 and 2002, respectively.

Research and development costs related to both present and future products are charged to expense in the period incurred.

Basic and diluted net loss per common share are computed based upon the weighted average number of common shares outstanding. Approximately 16.7 million common shares issuable as of December 31, 2003 upon the exercise of options and warrants are not included in the per share calculations since the effect of their inclusion would be antidilutive.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

The Company operates in a highly competitive and rapidly changing industry. Product revenues are currently concentrated with a limited number of customers, and the supply of certain materials is concentrated among a few providers. The development and commercialization of new technologies by any competitor could adversely affect the Company’s results of operations.

As of the reporting date, the Company had recorded unamortized goodwill assets resulting from the acquisitions of Spectral Solutions, Inc. and the Adaptive Notch Filter division of Lockheed Martin Canada, Inc., both during 2000. Beginning January 1, 2002, goodwill is no longer to be amortized but rather to be tested for impairment on an annual basis and between annual tests whenever there is an indication of potential impairment. Impairment losses would be recognized whenever the implied fair value of goodwill is determined to be less than its carrying value. During 2002, the Company completed the process of evaluating goodwill for impairment under SFAS No. 142. As the fair value, using quoted market prices for the Company’s common stock, exceeded the carrying amount, the goodwill was determined to be not impaired. During October 2003, the Company performed its annual evaluation of goodwill for impairment and no impairment was determined to exist, thus no write-downs were required.

Prior to the 2002 effective date of this standard, acquired goodwill from the two acquisitions during 2000 had been amortized using the straight-line method over eight years. The excess of cost over net assets acquired associated with assets acquired in a purchase business combination was included in impairment evaluations when events and circumstances may indicate impairment, management evaluated the recoverability of acquired goodwill by comparing the carrying value of the asset to the associated current and projected annual sales, operating profit, undiscounted annual cash flows and market value; management also considered business prospects, market trends and other economic factors in performing this evaluation. Based on this evaluation, there was no unrecorded permanent impairment related to acquired goodwill at December 31, 2001.

The following presents results of operations as though SFAS No. 142 had been in effect:

The Company adopted SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” effective January 1, 2002. SFAS No. 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets. This statement supersedes SFAS No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,” and the accounting and reporting provisions of Accounting Principles Board Opinion No. 30, “Reporting the Results of Operations — Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions,” for the disposal of a segment of a business. This adoption did not have a material effect on its results of operations or financial position.

In December 2002, the FASB issued SFAS No. 148, “Accounting for Stock-Based Compensation—Transition and Disclosure—an amendment of FASB Statement No. 123. This Statement amends SFAS No. 123, “Accounting for Stock-based Compensation,” to provide alternative methods of transition for a voluntary change to the fair value method of accounting for stock-based employee compensation. In addition, this Statement amends the disclosure requirements of SFAS No. 123 to require more prominent disclosures in both the annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method on reported amounts. The amendments to SFAS 123 in paragraphs 2(a)-2(e) of this Statement are effective for financial statements for fiscal years ending after December 15, 2002. The amendment to SFAS 123 in paragraph 2(f) of this Statement and the amendment to Opinion 28 in paragraph 3 are effective for financial reports containing condensed financial statements for interim periods beginning after December 15, 2002. The Company does not expect that adoption of this Statement will have a material effect on its results of operations or financial position.

The Company has a stock-based employee compensation plan, which is more fully described in note 6. The Company applies APB Opinion 25, Accounting for Stock Issued to Employees, and related Interpretations in accounting for its plans. Stock expense for the twelve month periods of 2003 and 2002, respectively, is the result of options issued with an exercise price below the underlying stock’s market price. The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of FASB Statement 123, Accounting for Stock-Based Compensation, using the assumptions described in Note 6, to its stock-based employee plans:

In January 2003, the FASB issued Interpretation No. 46 (FIN No. 46), “Consolidation of Variable Interest Entities.” This is an interpretation of Accounting Research Bulletin No. 51, and addresses consolidation by business enterprises of variable interest entities, which have certain characteristics. FIN No. 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. It applies in the first fiscal year or interim period beginning after June 15, 2003, to variable interest entities in which an enterprise holds a variable interest that it acquired before February 1, 2003. FIN No. 46 applies to public enterprises as of the beginning of the applicable interim or annual period, and it applies to nonpublic enterprises as of the end of the applicable annual period. FIN No. 46 may be applied prospectively with a cumulative-effect adjustment as of the date on which it is first applied or by restating previously issued financial statements for one or more years with a cumulative-effect adjustment as of the beginning of the first year restated. The Company does not expect that adoption of this interpretation will have a material effect on its results of operations or financial position.

In December 2002, the FASB SFAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure — an amendment of FASB Statement No. 123. This Statement amends SFAS No. 123, “Accounting for Stock-based Compensation,” to provide alternative methods of transition for a voluntary change to the fair value method of accounting for stock-based employee compensation. In addition, this Statement amends the disclosure requirements of SFAS No. 123 to require more prominent disclosures in both the annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method on reported amounts. The amendments to SFAS 123 in paragraphs 2(a)-2(e) of this Statement are effective for financial statements for fiscal years ending after December 15, 2002. The Company does not expect that adoption of this statement will have a material effect on its results of operations or financial position.

In April 2003, the FASB issued Statement of Financial Accounting Standards (“SFAS”) No. 149, “Amendment of Statement 133 on Derivative Instruments and Hedging Activities.” SFAS No. 149 amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging activities under SFAS No. 133, “Accounting for Derivative instruments and Hedging Activities.” SFAS No. 149 is effective for contracts entered into or modified after June 30, 2003. The Company believes that the adoption of SFAS No. 149 will not have a material impact on the Company’s results of operations or financial position.

In May 2003, the FASB issued SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity.” SFAS No. 150 establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. In November 2003, the FASB issued FASB Staff Position Number 150-3, which deferred indefinitely the effective date of SFAS No. 150 as it relates to certain mandatorily redeemable non-controlling interests. SFAS No. 150 was effective at the beginning of the first interim period beginning after June 15, 2003. The Company believes that the adoption of SFAS No. 150 will not have a material impact on the Company’s results of operations or financial position.

The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which contemplate continuation of the Company as a going concern. However, the Company has sustained substantial losses from operations in recent years, and such losses have continued through the year ended December 31, 2003. In addition, the company has used, rather than provided, cash in its operations.

In view of the matters described in the preceding paragraph, recoverability of a major portion of the recorded asset amounts shown in the accompanying balance sheet is dependent upon continued operations of the Company, which in turn is dependent upon the Company’s ability to meet its financing requirements on a continuing basis, to maintain present financing, and to succeed in its future operations. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.

The Company has incurred, and continues to incur, losses from operations. For the years ended December 31, 2003, 2002, and 2001, the Company incurred net losses of $7,156,075, $13,077,832, and $28,189,603, respectively. During those years the Company implemented strategies to reduce its cash used in operating activities. The Company’s strategy included the consolidation of its manufacturing and research and development facilities and a targeted reduction of the employee workforce, increasing the efficiency of the Company’s processes, focusing development efforts on products with a greater probability of commercial sales, reducing professional fees and discretionary expenditures, and negotiating favorable payment arrangements with suppliers and service providers.

To date, the Company has financed its operations primarily through public and private equity and debt financings. Subject to the uncommitted nature of the credit line, the Company believes that it has sufficient funds to operate its business as identified herein and to meet its obligations through 2004, provided that the Company is able to borrow the $1 million remaining under the uncommitted line of credit. Should this line not be available, the Company believes it has sufficient funds to operate into the third or fourth quarter 2004, and quite possibly beyond, depending on operating results. The Company intends to look into augmenting its existing capital position by utilizing the credit line as identified and through other sources of capital.

Cost of product sales for the years ending December 31, 2003 and 2002 includes approximately $130,000 and $295,000, respectively, of costs in excess of the net realizable value of inventory.

The Company has an authorized class of undesignated preferred stock consisting of 300,000 shares. Preferred stock may be issued in series from time to time with such designations, relative rights, priorities, preferences, qualifications, limitations and restrictions thereof, to the extent that such are not fixed in the Company’s certificate of incorporation, as the Board of Directors determines.

On February 9, 1996, the Board of Directors adopted a shareholder rights plan (the “Rights Plan”). In conjunction with the adoption of the Rights Plan, the Company created one series of preferred stock, consisting of 10,000 shares of Series A Junior Participating Preferred Stock (“Series A Preferred”). Each share of Series A Preferred would entitle the holder to receive dividends equal to 1,000 times the dividends per share declared with respect to the Company’s common stock and, in the event of liquidation, such holders would receive a preference of 1,000 times the aggregate amount to be distributed per share to the holders of the Company’s common stock. Pursuant to the Rights Plan, a Series A Right is associated with, and trades with, each share of common stock outstanding. The record date for distribution of such Series A Rights was February 22, 1996, and for so long as the Series A Rights are associated with the common stock, each new share of common stock issued by the Company will include a Series A Right. Each Series A Right will entitle its holder to purchase one one-thousandth of a share

of Series A Preferred for $200, subject to adjustment as defined in the Rights Plan. The Series A Rights are not exercisable until the earlier of (i) 10 days after any person or group becomes the beneficial owner of 15% or more of the Company’s outstanding common stock, or (ii) 10 business days (unless extended by the Board of Directors) after the commencement of a tender offer or exchange offer that would result in a person or group beneficially owning 15% or more of the Company’s outstanding common stock.

If any person or group (“Acquiring Party”) acquires 15% or more of the Company’s outstanding common stock (“Shares Acquisition Date”), each holder of a Series A Right, except the Acquiring Party, has the right to receive upon exercise (i) shares of the Company’s common stock having a market value equal to two times the exercise price of the Series A Right, and (ii) one Series B Right (Series A Rights and Series B Rights are hereinafter collectively referred to as the “Rights”). The Board of Directors has the option, after the Shares Acquisition Date but before there has been a 50% acquisition of the Company, to exchange one share of common stock (or one one-thousandth of a share of preferred stock) and one Series B Right for each Series A Right (other than Series A Rights held by the Acquiring Party).

If, after the Series A Rights become exercisable, the Company is involved in a merger or other business combination, or if the Company sells or transfers more than 50% of its assets or earning power, or if an acquiring party engages in certain “self-dealing” transactions with the Company, as defined in the Rights Plan, each Right then outstanding (other than Rights held by the Acquiring Party) will be exercisable for common stock of the other party to such transaction having a market value of two times the exercise price of the Right. The Company has the right to redeem each Series A Right for $0.01 prior to the Shares Acquisition Date. The Series B Rights, once issued, are not redeemable. The Rights expire on February 9, 2006.

On February 13, 2002, the Company executed an amendment to the Rights Agreement to provide that neither Elliott Associates, L.P. and Elliott International, L.P. (collectively referred to herein as “Elliott” and with their affiliates, the “Elliott Entities”) nor Alexander Finance, LP (“Alexander”) shall be an acquiring person under the Rights Agreement (i) on account of any acquisition of additional common shares purchased directly from ISCO which has been approved in advance by its Board of Directors, or (ii) so long as the acquisition of any additional shares not purchased directly from ISCO, in the aggregate, does not exceed one (1%) percent of the total issued and outstanding ISCO common stock. Additionally, none of the Elliott Entities nor Alexander will be an acquiring person by reason of direct transfers between any of the Elliott Entities or from Alexander to any of its affiliates.

At December 31, 2003, authorized but unissued shares of common stock have been reserved for future issuance as follows:

On August 19, 1993, the Board of Directors adopted the 1993 Stock Option Plan (the “Plan”) for employees, consultants, and directors who are not also employees of the Company (outside directors). This plan reached its ten-year expiration during 2003. During the 2003 annual meeting of shareholders, the Company’s shareholders approved a new 2003 Equity Incentive Plan to take the place of the expiring 1993 plan. Unissued options from the 1993 plan were used to fund the 2003 plan. The maximum number of shares issuable under these plans was 14,011,468.

For employees and consultants, the Plan provides for granting of Incentive Stock Options (ISOs) and Nonstatutory Stock Options (NSOs). In the case of ISOs, the exercise price shall not be less than 100% (110% in certain cases) of the fair value of the Company’s common stock, as determined by the Compensation committee or full Board as appropriate (the “Committee”), on the date of grant. In the case of NSOs, the exercise price shall be determined by the Committee, on the date of grant. The term of options granted to employees and consultants will be for a period not to exceed 10 years (five years in certain cases). Options granted under the Plan default to vest over a four year period (one-fourth of options granted vest after one year from the grant date and the remaining options vest ratably each month thereafter), but the vesting period is determined by the Committee. In addition, the Committee may authorize option grants with vesting provisions that are not based solely on employees’ rendering of additional service to the Company.

For outside directors, the Plan provides that each outside director will be automatically granted NSOs on the date of their initial election to the Board of Directors. On the date of the annual meeting of the stockholders of the Company, each outside director who is elected, reelected, or continues to serve as a director, shall be granted additional NSOs, except for those outside directors who are first elected to the Board of Directors at the meeting or three months prior. The options granted vest ratably over one or two years, based on the date of grant, and expire after ten years from the grant date.

On May 10, 1999, the Board of Directors granted to each employee of the Company (other than the executive officers of the Company) (collectively, the “Non-Executive Employees”) the option to (i) reduce the exercise prices of up to a maximum of 15,000 of the unexercised stock options previously granted to such Non-Executive Employee under the Plan to $.5625 per share (the closing price of the Company’s Common Stock on May 10, 1999) and (ii) cause all of such stock options not otherwise scheduled to become fully vested on or before May 10, 2000 to become fully vested on such date. As a result thereof, an aggregate of 279,550 stock options previously granted under the Plan were amended as described in the preceding sentence. In addition, on May 10, 1999 the Board of Directors granted to the executive officers and certain Non-Executive Employees of the Company additional non-statutory stock options to purchase an aggregate of 343,575 shares of the Company’s Common Stock under the Plan. Such stock options became fully vested on the first anniversary of the date of grant, with exercise prices of $.5625 per share and expire 10 years from the date of grant.

On July 1, 2000, Financial Accounting Standards Board Interpretation No. 44, “Accounting for Certain Transactions involving Stock Compensation, an interpretation of APB Opinion No. 25” (“FIN 44”) was adopted by the Company. FIN 44 requires that stock options that have been modified to reduce the exercise price be subject to variable accounting. The Company accounts for employee stock options under APB Opinion No. 25 and non-employee stock options under Statement of Financial Accounting Standards No. 123, “Accounting for Stock Based Compensation” (“SFAS No. 123”).

On May 10, 1999, as described above, the Company re-priced certain stock options granted to employees and in accordance with US GAAP, at that time, the Company accounted for the re-priced stock options as “fixed”. As a result of adopting FIN 44, the Company is required to apply variable accounting to these options. If the market price of the Company’s common stock increases above the July 1, 2000 market price, the Company will have to recognize additional compensation expense equal to the increase in stock price multiplied by the number of re-priced options. No additional expense will be recognized if the stock does not exceed the July 1, 2000 value. However, the impact cannot be determined as it is dependent on the change in the market price of the common stock from July 1, 2000 until the stock options are exercised, forfeited, or expire unexercised. Because the stock price on December 31, 2003 was below that of July 1, 2000, no expense has been recognized during the period.

On February 5, 2001, the Company’s Board of Directors authorized the re-pricing of certain “out of the money” stock options granted to employees during the calendar year of 2000 to the closing share price on such date, or $1.9375 per share. This re-pricing causes these options to be subject to variable accounting as described in FIN 44. Because the stock price on December 31, 2003, was lower than the re-priced strike price no gain or loss was recognized during the period.

On April 1, 2002, the Company’s Board of Directors authorized the re-pricing of certain “out of the money” stock options granted to employees. A new strike price of $0.81 per share was established, provided the respective employees remain with the Company for at least six months following the re-pricing date. In addition, certain stock options granted to directors were repriced, with a new strike price of $1.00 per share. As the stock price on December 31, 2003, was lower than the re-priced strike price no gain or loss was recognized during the period.

On July 17, 2000, the Company granted an option to a non-Company advisor in connection with the establishment of a sales office in Japan to purchase 200,000 shares of common stock at $4.9375 per share, the price of the common stock on the date of the grant. According to the Black-Scholes valuation model, the value of the option was $4.53 per share. The option vested 25% immediately, with the balance vesting pro-rata over a three-year period. $906,000 of non-cash compensation expense was to be amortized during the life of the options. This arrangement was terminated during December 2001, as a result of a change in the structure of the Japanese sales office. The cumulative compensation expense charged for these services through termination was $545,000.

On February 15, 2000, the Company’s Board of Directors granted to certain executive level employees an aggregate of 440,000 deferred stock units (“DSUs”) under the Company’s 1993 Amended and Restated Stock Option Plan (the “Plan”). The DSU’s represent the right to receive an equivalent number of restricted shares of the Company’s common stock. On the date of the grant, the DSU’s were set to vest at the rate of 10% on the first anniversary of the date of the grant, with the balance vesting at a rate of 20%, 30%, and 40% at the second, third, and fourth anniversary dates, respectively. The executive level employees had the right to elect to defer receipt of the common stock subject to the DSU’s to a later date. In the third quarter of 2000, the Company began to recognize compensation expense for the DSU’s over the vesting period (4 years) based on their intrinsic value of $1,925,000, which was the number of DSU’s multiplied by the closing price of the Company’s common stock on July 18, 2000, the measurement date ($4.38 per share). As of July 3, 2003, all DSU’s granted under this plan had been either received or cancelled. As a result of these transactions, unamortized deferred charges of $308,448 were eliminated. No additional expense is expected for this purpose.

On February 15, 2002, the Company completed a Shareholder Rights Offering. Approximately $20 million was raised from existing shareholders as of the recording date in exchange for the issuance of approximately 40 million shares of the Company’s common stock. A portion of the proceeds were then used to repay in full $9.8 million of debt and related accrued interest, as well as the payment of various other accrued expenses.

On October 31, 2003, the Company’s Board of Directors authorized the re-pricing of certain “out of the money” stock options granted to directors. A new strike price of $0.24 per share was established. A non-cash charge of $144,000 was recognized during the fourth quarter of 2003 to account for the difference between the re-priced strike price and the $0.55 closing price of the Company’s common stock on December 31, 2003.

On January 2, 2003, the Company’s Board of Directors granted 2,800,000 new stock options to six of the Company’s employees, including officers. 950,000 of these options vested immediately, while the remaining 1,850,000 vest monthly in 12 installments. All of the options granted on January 2, 2003 were granted at a discount based on 25% of the average closing price of the Company’s common stock as reported on the American Stock Exchange over ten trading days and ultimately valued at a $0.22 discount to the closing price of the Company’s common stock as of the date of the grant. A charge of $91,000 and $605,000 were recognized during the fourth quarter and full year 2003, respectively, to recognize the value of the discount. Additionally, certain of these options were deemed to be properly accounted for using variable accounting. As such, a charge of $275,000 was recognized during the fourth quarter 2003 to reflect the $0.55 closing price of the Company’s common stock as of December 31, 2003.

During July 2003, the Board of Directors cancelled approximately 2.8 million outstanding options held by certain Company employees, including officers.

During 2003, in addition to the disclosure above, the Company’s Board of Directors granted 770,000 stock options to the Company’s employees and non-employee Board members. These grants were issued at the closing market price on the date of grant.

Pro forma information regarding net income and earnings per share is required under FASB 123, and has been determined as if the Company had accounted for its stock options granted subsequent to December 31, 1994 under the fair value method of that Statement. The fair value for these options was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions for the years ended December 31, 2003, 2002 and 2001: risk-free interest rate of 2.3%, 2.9%, and 4.2%, respectively; a dividend yield of 0%; volatility factor of the expected market price of the Company’s common stock of 0.10, 0.15, and 0.56, respectively; and expected life of the options of 4.0 years.

The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options.

The table below summarizes all option activity during the three year period ended December 31, 2002:

The weighted-average exercise price of options outstanding at December 31, 2003, 2002 and 2001, was $0.55, 0.96, and 1.64, respectively. The weighted-average exercise price of options granted, exercised, and forfeited during 2003 was $0.16, $0.10 and $0.85, respectively. The weighted-average fair value of options granted during 2003, 2002 and 2001 was $0.16, $0.18, and $1.52, respectively.

Following is additional information with respect to options outstanding at December 31, 2003:

The total number of unvested options outstanding at December 31, 2003 was 646,000, which will vest based on employees’ continued service to the Company.

During the fourth quarter of 2002, in accordance with the terms of the credit line provided by the Company’s two largest shareholders, 10 million warrants were issued to purchase common stock of the Company at an exercise price of $0.20 per share and an expiration date of April 15, 2004. Pursuant to an agreement between the

parties during 2003, no additional warrants were issued related to borrowings on either the $4 million credit line or $2 million supplement. During February 2004, all 10 million warrants were exercised, resulting in the Company receiving the $2 million aggregate strike price and issuing 10 million shares of common stock.

The Company has net operating loss carryforwards for tax purposes of approximately $122,197,000 at December 31, 2003. The net operating loss carryforwards expire in the following years:

Significant components of the Company’s deferred tax assets and liabilities are as follows:

The valuation allowance increased during 2003 and 2002 by $3,164,000 and $4,290,000, respectively, due primarily to the increase in the net operating loss carryforward. Based on the Internal Revenue Code and changes in the ownership of the Company, utilization of the net operating loss carryforwards will be subject to annual limitations.

The Company leases its manufacturing and office space. Under the terms of the lease in Mount Prospect, IL, which expires October 2004, the Company is responsible for all real estate taxes and operating expenses. In addition, the Company had lease commitments for its Canadian facility expiring August 2004, which was subsequently broken into two parts and successfully subleased to third parties as of March 1, 2003.

Future minimum payments under the operating leases consist of the following at December 31, 2003:

Rent expense totaled $302,000, $450,000, and $690,000, for the years ended December 31, 2003, 2002, and 2001, respectively.

The Company has a 401(k) plan covering all employees who meet prescribed service requirements. The plan provides for deferred salary contributions by the plan participants and a Company contribution. Company contributions, if any, are at the discretion of the Board of Directors and are not to exceed the amount deductible under applicable income tax laws. No Company contribution was made for the years ended December 31, 2003, 2002, and 2001.

On March 26, 2002, the Company replied to Conductus’ and Superconductor Technologies’ Second Amended Answer and Counterclaims and filed counterclaims alleging that Conductus and Superconductor Technologies also infringe U.S. Patent No. 6,104,934 entitled “Cryoelectronic Receiver Front End” and U.S. Patent No. 6,205,340 B1 entitled “Cryoelectronic Receiver Front End For Mobile Radio Systems”. On April 17, 2002, the court dismissed these (the Company’s) counterclaims without prejudice to the Company’s right to assert these counterclaims in a separate action.

During February 2004, the parties reached settlement. Laves was paid $700,000, half of which from the Company and the remainder from the Company’s insurance carrier, and all parties agreed to terminate proceedings, with prejudice.

The Company adopted SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information” SFAS No. 131 requires a business enterprise, based upon a management approach, to disclose financial and descriptive information about its operating segments. Operating segments are components of an enterprise about which separate financial information is available and regularly evaluated by the chief operating decision maker(s) of an enterprise. Under this definition, the Company operated as a single segment for all periods presented.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.

(a) An evaluation was performed under the supervision and with the participation of the Company’s management, including its Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO, of the effectiveness of the Company’s disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as of December 31, 2003. Based on that evaluation, the Company’s management, including the CEO and CFO, concluded that the Company’s disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act, is recorded, processed, summarized and reported as specified in Securities and Exchange Commission rules and forms.

(b) There were no significant changes in the Company’s internal control over financial reporting identified in connection with the evaluation of such controls that occurred during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

The Company’s Board of Directors currently consists of five directors. The board consists of three classes of directors, with each director serving a three-year term.

He joined AT&T in 1958 as a member of the technical staff of Bell Laboratories and went on to management positions in consumer products, customer switching systems engineering and network planning.

Mr. Powers is a member of both the Audit Committee and the Compensation Committee, the latter of which he serves as its Chairman.

The Audit Committee consists of three directors, Stuart Chase Van Wagenen (Chairman), James J. Fuentes and Tom L. Powers, all of whom are “independent” as defined by the rules of the Securities and Exchange Commission and American Stock Exchange. The Board of Directors has determined that Mr. Van Wagenen is an “audit committee financial expert” as defined in regulations of the Securities and Exchange Commission under the Sarbanes-Oxley Act of 2002.

The Company has a Code of Business Conduct and Ethics, which is attached as an exhibit to this annual report. The Company requires all employees, officers and directors to adhere to this Code in addressing the legal and ethical issues encountered in conducting their work. The Code of Business Conduct and Ethics requires that the Company’s employees avoid conflicts of interest, comply with all laws and other legal requirements, conduct business in an honest and ethical manner, and otherwise act with integrity and in the Company’s best interest. The Company’s Code of Business Conduct and Ethics is intended to comply with Item 406 of the SEC’s Regulation S-K and the rules of the American Stock Exchange.

The Code of Business Conduct and Ethics includes procedures for reporting violations of the Code, which are applicable to all employees. The Sarbanes-Oxley Act of 2002 requires companies to have procedures to receive, retain and treat complaints received regarding accounting, internal accounting controls or auditing matters and to allow for the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters. The Code of Business Conduct and Ethics also includes these required procedures.

During 2003, Tom L. Powers was the sole member of the Compensation Committee of the Board of Directors. Mr. Powers does not currently serve as an officer of the Company. There are no compensation committee interlocks between the Company and any other entity involving the Company’s or such entity’s executive officers or board members. Neither Mr. Van Wagenen nor Mr. Fuentes, who joined the Compensation Committee during 2004, are officers of the Company or have similar interlocks.

Set forth below is a table identifying executive officers of the Company who are not identified in the tables entitled “Directors” Biographical information for Dr. Abdelmonem is set forth above under “Directors.”

Mr. Cesario joined the Company during August 2000 as Controller and was named Acting Chief Financial Officer in April 2002 and Chief Financial Officer in December 2002. Previously, Mr. Cesario was Group Controller for copper and brass producer Outokumpu Copper, Inc. and subsidiaries, a U.S. group with approximately $500 million in annual revenue and owned by Helsinki-based Outokumpu Oyj. Mr. Cesario has an MBA (Finance) from DePaul University in Chicago, a B.S. in Accountancy from the University of Illinois, and began his career at KPMG Peat Marwick.

The Board of Directors elects officers annually and such officers, subject to the terms of certain employment agreements, serve at the discretion of the board. See “Executive Compensation”. The Company has entered into an employment agreement with Dr. Abdelmonem. There are no family relationships among any of the directors or executive officers of the Company.

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires the Company’s officers (as defined under Section 16(a) of the Securities Exchange Act), directors and persons who own greater than 10% of a registered class of the Company’s equity securities to file reports of ownership and changes in ownership with the Securities and Exchange Commission. Based solely on a review of the forms it has received and on written representations from certain reporting persons that no such forms were required for them, the Company believes that during 2003, all of the Section 16(a) filing requirements applicable to its officers, directors and 10% beneficial owners were complied with by such persons.

The following table provides information concerning the annual and long-term compensation for services in all capacities to the Company for the years ended December 31, 2003, 2002 and 2001 of (i) each person who served as the Company’s chief executive officer and (ii) the four most highly compensated executive officers whose salary and bonus for services rendered in all capacities to the Company for the fiscal year ended December 31, 2003 exceeded $100,000 (collectively, the “Named Executive Officers”).

The following table contains information concerning the grant of stock options by the Company to the Named Executive Officers during 2003. There were no stock appreciation rights granted in 2003. Information provided in this table is as of December 31, 2003.

The following table provides information concerning the Named Executive Officers’ unexercised options at December 31, 2003. None of the Named Executive Officers held or exercised any stock appreciation rights, during 2003.

The Company has an employment agreement with Amr Abdelmonem dated as of January 1, 2001 to be Chief Technology Officer of the Company. Dr. Abdelmonem subsequently became the Chief Executive Officer of the Company in June 2002. The agreement is for a term of three years, with one year renewal options. Dr. Abdelmonem is paid an annual salary of $200,000 and is paid a severance of one year’s salary if (i) the Company terminates his employment without Cause (as defined in the agreement) or (ii) Dr. Abdelmonem terminates his employment for Good Reason (as defined in the agreement), which such severance is offset by any income received by Dr. Abdelmonem during the severance period. His severance is increased to two years salary in the case of a change in control (as defined in the agreement) of the Company and a termination as described previously. Dr. Abdelmonem also receives a severance of six months salary if his employment contract expires without renewal. Dr. Abdelmonem’s agreement includes a provision for a bonus to be paid at the discretion of the Board of Directors and certain non-competition, non-solicitation, assignment of invention and confidentiality provisions.

In December 2002, the Board of Directors authorized a bonus pool of up to $300,000 in which all officers, including Dr. Abdelmonem and Mr. Cesario, shall be eligible to participate in the event that the Company achieves two consecutive quarters of positive cash flow results after taking into account the payment of such bonuses. In the event the condition is achieved, the amount Dr. Abdelmonem and Mr. Cesario may receive from such pool shall be determined in the discretion of the Board.

Each Director receives an annual retention fee of $5,000 on the first business day of each fiscal year. In addition, the Chairman of the Board and the Chairman of the audit committee each receive additional $5,000 retention fee and the Chairman of the Compensation Committee receives a $1,000 retention fee.

In addition, the Board has established a compensation policy to provide that each Non-Employee Director who is re-elected or continues to serve as a director because his or her term had not expired shall be granted an option to purchase 50,000 shares of common stock at the reported closing price of the common stock on the date of each annual meeting of the stockholders of the Company, provided that no such automatic grant shall be made to a Non-Employee Director who was first elected to the Board of Directors at the first such meeting or was first elected to the Board of Directors within three months prior to such annual meeting. Such options vest monthly over a one year period from the date of grant.

In addition, the current policy provides for the grant of Non-Qualified Stock Options (“NQSOs”) to purchase 25,000 shares of common stock to each Non-Employee Director who is appointed or continues to serve on the audit committee of the Board of Directors and the Chairman of the audit committee receives a grant of NQSOs to purchase 50,000 shares of common stock. Each Non-Employee Director who is appointed or continues to serve on the compensation committee of the Board of Directors receives a grant of NQSOs to purchase 10,000 shares of common stock and the Chairman of the compensation committee receives a grant of NQSOs to purchase 25,000 shares of common stock . The Chairman of the Board receives a grant of NQSOs to purchase 50,000 shares of common stock. These options are granted in consideration of such director’s service on a committee or as Chairman. Each of the options are granted at the reported closing price of the common stock on the date of each annual meeting of the stockholders of the Company or on the date such director joins a committee or is named

Chairman of such Committee, provided that annual grants are not made to a Non-Employee Director who was first appointed to the committee or as chairman within three months prior to such annual meeting. These stock options vest monthly over a one year period from the date of grant and expire ten years from the date of grant.

All Non-Employee Directors are reimbursed for their reasonable out-of-pocket expenses incurred in attending board and committee meetings.

The following table gives information about the Company’s common stock that may be issued upon the exercise of options, warrants and rights under the Company’s 1993 Plan and under the 2003 Equity Incentive Plan as of December 31, 2003.

(1) The 1993 Plan terminated in August 2003 and was replaced by the 2003 Equity Incentive Plan.

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

The following table sets forth information regarding the beneficial ownership of Common Sock as of March 23, 2004, except as otherwise indicated in the relevant footnote, by (1) each person or group that the Company knows beneficially owns more than 5% of Common Stock, (2) each of the Company’s directors and director nominees, (3) the Named Executive Officers, and (4) all current executive officers and directors as a group. Unless otherwise indicated, the address of each person identified below is c/o the Company at its principal executive offices.

The percentages of beneficial ownership shown below are based on 160,410,670 shares of Common Stock outstanding as of March 23, 2004, unless otherwise stated. Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission and generally includes those securities over which a person may exercise voting or investment power. In addition, shares of Common Stock which a person has the right to acquire upon the exercise of stock options and/or warrants within 60 days of the date of this table are deemed outstanding for the purpose of computing the percentage ownership of that person, but are not deemed outstanding for computing the percentage ownership of any other person. Except as indicated in the footnotes to this table or as affected by applicable community property laws, the persons named in the table have sole voting and investment power with respect to all shares of Common Stock beneficially owned.

During October 2002, the Company entered into an Uncommitted Line of Credit with its two largest shareholders, an affiliate of Elliott Associates, L.P. (Manchester Securities Corporation and Alexander Finance, L.P.). This line provided that up to $4 million may be borrowed by the Company, with $1 million borrowed during October 2002 upon completion of the transaction. $1 million was borrowed during November 2002 and a third borrowing of $1 million occurred in March 2003. This line is uncommitted, such that each new borrowing under the facility would be subject to the approval of the lenders. If approved by the lenders, the Company may borrow up to an additional $1 million.

Borrowings on this line bear an interest rate of 9.5% and are collateralized by all the assets of the Company. Outstanding loans under this agreement would be required to be repaid on a priority basis should the Company receive new funding from other sources. Additionally, the lenders are entitled to receive warrants to the extent funds are drawn down on the line. The warrants bear a strike price of $0.20 per share of common stock and expire on April 15, 2004. The credit line matures and is due, including accrued interest thereon, on March 31, 2004. Due to an agreement between the parties that did not provide warrants with respect to the most recent $2 million in borrowings, a maximum of 10 million warrants were issued as a result of this transaction.

On October 24, 2003, the Company and the lenders amended the terms of their loan agreement to reflect: (i) an increase in the aggregate commitment of the lenders to from $4,000,000 to $6,000,000; (ii) the elimination of warrant issuances from future drawdowns; (iii) interest on future loans will bear interest at the rate of 14% per annum; (iv) that future loans mature on October 31, 2004; (v) and that future loans be subject to the discretion of the Lenders. The Company borrowed $1,000,000 from the line of credit agreement upon execution of the amendment. During February 2004, these credit lines were extended to a due date of April 2005, with interest after the initial periods to be charged at 14%, and the lenders exercised warrants to purchase 10,000,000 shares of common stock. The Company received the $2,000,000 aggregate strike price for the exercise of these warrants.

Grant Thornton LLP has served as the Company’s independent certified public accountants since December 2000. Grant Thornton LLP has been selected to continue as the Company’s independent certified public accountants for the current year. A representative of that firm is expected to be present at the annual meeting, will have the opportunity to make a statement if he or she desires to do so and will be available to respond to appropriate questions.

During the fiscal years ended December 31, 2003 and 2002, fees in connection with services rendered by Grant Thornton LLP, the Company’s independent auditors, were as set forth below:

Audit fees consisted of fees for the audit of the Company’s annual financial statements and review of quarterly financial statements as well as services normally provided in connection with statutory and regulatory filings or engagements, consents and assistance with and review of the Company’s documents filed with the SEC.

Tax fees consisted primarily of fees for tax compliance, tax advice and tax planning services.

The Company made no other payments to Grant Thornton LLP during 2003 which constituted other fees.

The Audit Committee’s policy is to pre-approve all audit services and all non-audit services that the Company’s independent auditor is permitted to perform for us under applicable federal securities regulations. As permitted by the applicable regulations, the Committee’s policy utilizes a combination of specific pre-approval on a case-by-case basis of individual engagements of the independent auditor and pre-approval of certain engagements up to predetermined dollar thresholds that are reviewed annually by the Committee. Specific pre-approval is mandatory for the annual financial statement audit engagement, among others.

All engagements of the independent auditor to perform any audit services and non-audit services have been pre-approved by the Committee in accordance with the pre-approval policy. The policy has not been waived in any instance.

The Audit Committee may delegate pre-approval authority to the Chairman of the Audit Committee. The Chairman of the Audit Committee must report any decisions to the audit committee at the next scheduled meeting.
