BUSINESS General InterDigital Communications Corporation (collectively with its subsidiaries referred to as InterDigital, the Company, we, us and our) specializes in the design and development of technology content and system solutions for advanced digital wireless communications applications. Over the course of our nearly thirty-year history, we have amassed a substantial and significant library of know-how and patents related to digital wireless technology. We market our technologies and solutions capabilities primarily to telecommunications equipment producers and related suppliers for embedding into products targeted for the following applications: - Mobile phones - Personal digital assistants - Mobile computing devices - Base stations and other infrastructure equipment - Other terminal-end wireless devices. In addition, we license our Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA) patents and technology to third parties. We are continuing to broaden and deepen our extensive body of technical know-how and broad patent portfolio related to wireless technologies. The Company is a public corporation, incorporated in Pennsylvania in 1972. Our corporate and administrative offices are located in King of Prussia, Pennsylvania. Our development teams are located in Melville, New York and King of Prussia, Pennsylvania. Wireless Telecommunications Industry Overview The wireless telecommunications industry is undergoing rapid growth worldwide. At the same time, new technologies and products are being developed to substantially enhance the capabilities and performance of wireless services available to consumers. The combination of rapid growth in the sales of wireless devices and accelerating technological change sets the stage for a revolution in wireless services that should fuel growth in the industry for many years. The wireless market is in the early stage of a shift from voice-oriented wireless products (primarily handsets which provide basic voice service on the move) to data-oriented devices which provide voice as well as high speed data to support advanced services including imaging and wireless Internet access. Consumers are likely to gain access to these services through a broad range of mobile terminal-end products, including handsets, personal digital assistants, and laptop or notebook computers, among other products. Demand for new wireless technology, which should enable the mobile devices to deliver advanced services, is likely to grow with the market for mobile products and services. Industry Growth Projections The evolving market for advanced wireless products and services is generally referred to as the third generation (3G) market. First generation wireless services were introduced in the 1980s, utilizing analog technology. Second generation (2G) services were introduced in the 1990s, taking advantage of new digital technology which greatly increased the capacity and flexibility of wireless networks. The first and second generations of wireless services delivered voice service with little or no ability to transmit data. The third generation of products will be designed to add data communications capability and, when broadly deployed, should enable global roaming for wireless users. 2 The market's 3G emergence is expected to be evolutionary rather than revolutionary. Wireless service providers are likely to install network infrastructure gradually over a period of years. Industry analysts expect the first 3G products and services to be introduced in Japan in 2001, with service in other parts of Asia, Europe and North America following throughout this decade. As the market expands, it is likely to spark a dynamic product development environment, with traditional wireless equipment producers and new market entrants bringing a wide range of terminal-end mobile devices to consumers. The great majority of those products are expected to utilize advanced air interface technology to deliver a combination of voice and high data-rate services. At the end of 1999, almost 500 million wireless subscribers utilized the current wireless products and services around the world. Market analysts expect that number to double over the next three years and grow to well over 1 billion subscribers by 2005. On an annual basis, industry analysts project that handset sales are expected to grow from more than 200 million in 1999 to nearly 600 million in 2003. Market penetration for wireless products should grow as well during the next several years. The highest penetration of wireless users today is in the Scandinavian countries and Hong Kong, where between 60 and 70 percent of the population owns and uses a mobile phone. In most developed nations, wireless penetration totals at least 20 percent of the population. In the United States, it reached approximately 25 percent at the end of 1999. Penetration is much lower in developing countries. Most industry observers forecast substantial growth in wireless's penetration of the population in both the developed and developing countries throughout this decade. Even with the growth in penetration for wireless devices worldwide, wireless telecommunications at the end of 1999 accounted for only about 3 percent of total telecommunication minutes of use. By 2003, analysts forecast that wireless minutes of use, as a percentage of total telecommunications, will grow to just under 12 percent. Industry observers expect that the use of advanced wireless technology in mobile computing products will grow rapidly during this period as well. Analysts forecast that, through 2003, unit shipments of notebook computers, ultra- portables, and palm-sized computers will grow by almost 22 percent per year worldwide. Experts predict that high-data rate wireless technology will be embedded in these products over the next several years, providing an additional market for advanced wireless technology. Taken together, these forecasts portray a market that should undergo significant growth over the next five years and which should have substantial room for additional growth thereafter. The Technology Landscape Two principal digital wireless technologies are in use today to enable wireless applications: TDMA and CDMA. Standards employing these technologies have been adopted around the world. The Global System for Mobile Communications (GSM) and IS 54/136, which utilize TDMA technology, serve the large majority of wireless subscribers worldwide. GSM is the far more dominant technology, being widely deployed in Europe, Asia, Africa, the Middle East and other regions (including the United States) . IS 54/136 has been deployed in North America, and Central and South America. IS-95, which employs narrowband CDMA technology, was commercialized in the 1990s and serves a smaller percentage of users today, primarily in the United States, Korea and several other countries. We have been developing TDMA and CDMA technologies for many years for fixed and mobile applications. With regard to TDMA, we were a leader in establishing IS-54 as a wireless standard in the United States in the 1980s and have established a substantial portfolio of patented TDMA inventions. Our core TDMA inventions include (among others): 3 - The fundamental architecture of commercial Time Division/Frequency Division Multiple Access (TD/FDMA) systems. - Methods of synchronizing the operation of TD/FDMA systems. - A unique approach of managing system capacity and maintaining agility through the reassignment of online subscriber units to different time slots and/or frequencies in response to system conditions. - The design of a multi-component base station where the intelligence is distributed allowing for more robust performance. - Initializing procedures that enable roaming. A number of our core TDMA inventions are central to 2G wireless systems in use today, being used in a broad range of wireless networks and terminal-end mobile devices produced by other companies worldwide. TDMA technology that we developed was also utilized as the air interface solution for the wireless local loop (WLL) products we developed and produced during the past 15 years. On the CDMA front, we acquired in 1992 a technology development company that had been involved in fundamental research in CDMA technology, with an emphasis on wideband or broadband application, since the mid- 1980s. We expanded that development program, anticipating the demand for wide bandwidth technology that would enable high data-rate wireless services. As part of that development work, we designed and produced a state-of-the-art system-on-a-chip Application Specific Integrated Circuit (ASIC) which contained our proprietary Broadband Code Division Multiple Access(TM) (B-CDMA(TM)) technology which was initially deployed in WLL products. Many of the essential elements of the B-CDMA solution are applicable to advanced high data rate products that are being developed for the 3G market. As with our TDMA inventions, we have patented our CDMA inventions and today hold a significant portfolio of patents for CDMA technology worldwide. Our key CDMA inventions include (among others): - The use of a common pilot channel to synchronize subchannels in a multiple access environment. - Various techniques for bandwidth allocation, including multi-channel and multi-code mechanisms. - Highly efficient schemes for controlling the transmission power output of terminal and base station devices vital in a CDMA system. - Communication system overlay techniques, which allow new wireless systems to be deployed with existing wireless technologies without frequency reallocation. - Joint detection and interference cancellation for reducing multiple access interference in a physical receiver. - Enhancements to soft handover techniques between designated cells. - Various subchannel access and coding techniques. We believe that certain of our inventions are essential to the implementation of the 2G IS-95 systems (See "- Business Activities. Patent and Technology Licensing".) Also, in 1999, a study group of the International Telecommunications Union (ITU), an agency for the United Nations responsible for establishing telecommunications standards, approved a new standard for 3G wireless networks designed to enable global roaming for mobile users and compatibility with the dominant existing wireless standards. The IMT-2000 standard, also referred to as the 3G wireless standard, defines five sets of alternative specifications for the digital mobile radios which can be selected or aggregated by equipment manufacturers to produce standards-compliant third generation wireless products for their customers. The five specifications under the standard include three forms of CDMA technology: TDD and FDD - forms of wideband CDMA, and FDD Multi-carrier CDMA (referred to as cdma-2000). The standard also includes two forms of TDMA technology: Digital Enhanced Cordless Telephone (DECT), and UWC-136, an evolved form of the U.S. TIA/EIA-136 digital cellular standard. Products built to one or more of these specifications are being designed to 4 deliver a varying range of high bandwidth wireless services, including high speed Internet access, multimedia communications, video conferencing, and other forms of data transmission. We made numerous contributions to the 3G standards bodies as the standard was being formulated and expect to continue to do so as the standard is refined. Many of our contributions are included as part of the standard adopted by the ITU study group. We believe that our patent portfolio is applicable to all of the air interface protocols described in the standard, and we have indicated to the standard setting bodies that we hold patents and patent applications that are either essential or commercially important for 3G products built to present standards specifications. Our current technology development programs are focused on creating solutions (including ASICs) for the wideband CDMA protocols of the 3G standard. We have focused on this market segment, in part, based on industry analysts' expectations that wideband CDMA technology (as opposed to the other 3G protocols) will serve the largest number of wireless subscribers as the 3G market grows. For many GSM service providers, wideband CDMA is likely to be the preferred 3G air interface protocol because its adoption offers them the least expensive and fastest route to 3G services. Given the dominant global market position today of the GSM service providers, analysts expect that they will maintain a dominant market position in the next generation market. Technology providers serving this market could benefit from a leading market position for wideband CDMA. We believe that our heritage of know-how and patented wireless inventions based upon both TDMA and CDMA air interface protocols presents us with attractive opportunities to provide technology in the 3G market. Strategy Our strategic objective is to create long-term growth as one of the leading developers of advanced air interface and full system-on-a-chip technology for the wireless communications industry. To achieve this objective, we are actively participating in worldwide 3G markets, with the following focus: - - Emphasizing Core Technology Development and System Design Capability. We possess longstanding core competencies in digital air interface design and the development of full system solutions for wireless products. By building on these strengths, we can give our customers the full advantage of the depth of our engineering know-how and long heritage of wireless inventions that enhance the effectiveness of end products. - - Building a Base of Strategic Relationships. To secure our position in the 3G market and define our growth opportunities, we intend to establish a network of customer/partner relationships to complement our strengths and enhance our ability to create value in a broader market. We seek partners that bring complementary technologies, production capability and market access. A key ingredient in the strategic plan is to work in partnership with a semiconductor producer to bring a number of standards-compliant 3G ASICs to market. - - Leveraging Technology and Intellectual Property Rights into 3G Standards and Products. We have been a leader in developing and promoting key industry standards starting with 2G in the 1980s as well as the recently proposed 3G standard. We believe this strategy enables us to promote the adoption of our technology into new standards-based products, providing our customers time to market and other advantages. - - Licensing Intellectual Property Worldwide. Our substantial portfolio of patented TDMA and CDMA inventions is a unique asset. Access to these inventions, and the technological know-how they represent, through licensing agreements has proven valuable to producers of wireless devices who provide advanced services around the world. By continuing to build our licensing program, we believe that we can capture substantial value in the future. - - Providing Specialized Engineering Services. We intend to selectively enter into agreements to develop technology for leading companies and offer integration technology and implementation assistance. Our goals 5 are to stay in close touch with market demands, take advantage of technology re-use opportunities, build our base of core technology and add to our portfolio of patented inventions. Business Activities Core Technology and Product Development Through 1999, the Company was engaged in the development, marketing, sales and servicing of WLL equipment utilizing our technology. We redirected our business plan in 1999. Driven by the emergence of the 3G market, intensified product and price competition in the WLL market, and a significant decline in demand worldwide for WLL systems, we sought to enter into arrangements with key equipment providers involving 3G technology and products. The proposed 3G technologies incorporated wideband CDMA protocols as well as other CDMA and TDMA technologies. A significant part of our business activity involves the development of core technology building blocks for the two aspects of the wideband CDMA protocol: Time Division Duplex (TDD) and Frequency Division Duplex (FDD) technologies. Executing on our business plan, we entered into a strategic engineering relationship with Nokia in 1999 involving the development of high data-rate 3G technology. In 1999, we also initiated a self-funded research and development effort to develop building blocks for other components of the wideband CDMA protocols included in the 3G Standard. The TDD format operates by using a single frequency band to transmit signals alternately in the forward and reverse direction. In the TDD scheme, the relative capacity of the forward and reverse links can be altered in favor of one direction (usually the forward). This is accomplished by giving a greater time allocation to forward transmission intervals than reverse by allocating more time slots. This asymmetry is useful for communication processes characterized by unbalanced information flow. One important example of this technique is Internet access in which users typically enter short messages and receive large information payloads. Importantly, due to the fact that only one carrier is used, frequency re-use is enhanced and planning is simplified. FDD supports two-way radio communication using paired radio frequencies. In the FDD format, one frequency supports transmission from a base station to a mobile terminal (the forward link) while the other frequency supports transmission in the reverse direction. Because of the paired frequencies, simultaneous communication in both directions is possible. This technique is ideal for high volume mobile voice traffic and is the traditional cellular and PCS radio spectrum allocation format. It is designed to be extremely flexible, providing high-quality voice transmission, along with high speed wireless Internet access and multimedia imaging. Based on these core technology building blocks, we intend to develop 3G products for sale to telecommunications equipment manufacturers. Those products could include ASICs, software and combined RF/Baseband boards, among others. Our business plan is to develop such products either alone or through partnering relationships with appropriate companies. We expect to also seek to license the technology to third parties on a royalty-bearing basis. (See "- Patent and Technology Licensing".) We are currently targeting a TDD ASIC, as well as dual and tri-mode ASICs incorporating TDD functionality. The initial ASICs would be targeted for mobile handsets; however, we may also extend our TDD ASIC offering to the infrastructure market segment. We are also currently developing our next generation FDD system-on-a-chip. Our engineering team is developing the technology for a system-on-a-chip solution, including the complex software and specifications for the manufacture of ASICs which can be embedded into a range of wireless products. The initial target product for the FDD 6 ASIC will be mobile handsets. The FDD development effort was initiated in 1999 following the completion of our second generation FDD system-on-a-chip (which we called our B-CDMA ASIC), developed in conjunction with Texas Instruments, Inc. The B-CDMA ASIC was designed for fixed wireless access products but employs FDD, TDD and wideband-CDMA technology components. The B-CDMA ASIC has been fabricated and successfully tested. This experience provides us with an important first step toward developing a commercial FDD system-on-a-chip solution since the B-CDMA ASIC already contains a significant percentage of the technology building blocks that will be used to design our new FDD ASIC. In the first half of 1999, we made a major shift in our business strategy by dedicating our resources into the emerging 3G market. As part of that undertaking, we decided to discontinue the further development and manufacture of WLL products. The decision to move away from the manufacture of WLL products was also driven by intensified product and price competition and a shift in world markets away from WLL systems, among other things. Since that time, we have been winding down all remaining commercial aspects of that business. InterDigital recorded expenses of $20.5 million, $17.2 million, and $24.2 million during 1999, 1998 and 1997, respectively, related to all of its research and of development efforts for TDMA, B-CDMA and 3G based product and technology development. Revenues recognized in 1999, 1998 and 1997 associated with development efforts were $13.9 million, $8.0 million and $4.4 million, respectively. At December 31, 1999, InterDigital's backlog of orders for UltraPhone(R) telephone equipment and services was approximately $5.1 million. All of this backlog is expected to be shipped in 2000. Backlog as of December 31, 1998 was approximately $1.0 million. The following table sets forth, for the periods indicated, the revenues from each revenue category as a percentage of total revenues and gross margins from product sales: 1999 1998 1997 ---- ---- ---- Revenues: Product Revenues 6.4% 6.8% 88.0% Licensing and Strategic Partner 93.6 93.2 12.0 ----- ----- ----- Total Revenues 100.0% 100.0% 100.0% ===== ===== ===== Revenues by customer geography are as follows (in thousands): Year Ended December 31, 1999 1998 1997 ---- ---- ---- U.S. $ 1,660 $ 1,873 $ 2,853 Non-U.S. 69,007 97,348 $46,983 ------- ------- ------- $70,667 $99,221 $49,836 ======= ======= ======= In 1999, 60% of InterDigital's revenue was from our customer in Finland. An additional 26% of revenue was from Japan. In 1998, more than 84% of total revenue was derived from our customers in Japan. In 1997, 66% of revenues were from Indonesia. Additionally, 6% of revenues were from our Philippine customer and another 6% of 1997 revenues were derived from our strategic partner in Korea. 7 Strategic Engineering Services. Based on the core competencies of our engineering team resulting from research and development work in TDMA and wideband CDMA technical areas dating back to the 1980s, we believe that we are positioned to deliver valuable engineering services to companies seeking to develop 3G compliant technologies and product embodiments. We anticipate that our engineering services could take on a number of forms. Because the 3G market is in its early stage, we believe that we can help companies develop core technology for their 3G products. In the first of such arrangements, we entered into a strategic technology development agreement in February 1999 with Nokia covering the development of new technology for 3G wireless communications products designed for high data rate applications, such as Internet access. The agreement provides that we are to deliver technology building blocks for Nokia to use in 3G wireless products. It also provides that Nokia will fund the project, maintain an active role in the development plan and, when the development is complete, be able to use the technology in 3G products. We will own the developed technology and will have the ability to license the technology to other companies, as well as design, manufacture, sell and use products and components that utilize the resulting technology. Nokia has the right to terminate the agreement both for convenience (with certain financial ramifications) and for cause. We anticipate offering a second form of strategic engineering services in which we would assist equipment suppliers in developing specific products based on our existing TDD or FDD technology. As part of this service, we would build upon the existing core technology and provide our customers with technology integration and applications engineering for their 3G products. We may also develop reference designs which the customer could use to customize their product. We anticipate that while such services may be attractive to a wide number of companies, our target market for such services will typically be the second and third tier producers. The competitive landscape in this market is changing. Traditionally, most telecommunications companies develop product and application designs in-house. While in-house engineering and development staffs, particularly at well-resourced companies, represent a competitive threat to our strategic engineering services market strategy, the shortage of qualified engineers, the need for background technology, and the fast pace of market development, has created an opportunity for companies like InterDigital that can provide ready access to both engineering talent and relevant know-how. Other companies are competing in this space, seeking to provide comparable engineering services. While these companies may have qualified engineers and relevant know-how, we believe we have a competitive advantage over such companies because of our deep history in TDMA and CDMA technologies (which form the foundation of 3G technologies), and our system and semiconductor design experience. Nonetheless, we cannot predict what level of market share, if any, that we will capture of the strategic engineering services market. Patent and Technology Licensing Since our inception, we have employed an aggressive program of acquiring and protecting of intellectual property. Our wholly-owned subsidiary, InterDigital Technology Corporation (ITC), currently holds approximately 137 United States patents and approximately 345 foreign patents relating specifically to digital wireless radiotelephony technology (TDMA and/or CDMA) which expire at various times beginning in 2004 and ending in 2015. ITC also has approximately 25 other patents, both in the United States and in non-U.S. countries. ITC has also filed approximately 76 United States and approximately 213 foreign patent applications relating primarily and variously to the CDMA and TDMA technologies. During 1999, ITC received 37 new patents, 22 in the United States (the majority of which were for CDMA inventions) and applied for more than 50 new patents worldwide. ITC's patents have effective terms of up to 20 years from the date of their first filing. In 1992, we undertook a comprehensive patent licensing program, the ultimate objective of which is the realization of licensing revenues from third party use of inventions underlying ITC's patent portfolio. ITC believes that, in many instances, licenses for certain of its patents are required in order for third parties to manufacture and sell digital cellular products in compliance with TDMA-based standards currently in use worldwide. Those standards 8 include, but are not limited to the, U.S Digital Cellular (IS-54/136) the Global System for Mobile Communication, the Pan- Asian Digital Cellular Standard, Digital Enhanced Cordless Telephone and Personal Handyphone System. Currently, numerous manufacturers supply digital cellular equipment conforming to such standards. ITC offers non-exclusive, royalty bearing patent licenses to telecommunications manufacturers that manufacture, use or sell, or intend to manufacture, use or sell, equipment that utilizes our extensive portfolio of intellectual property. At December 31, 1999, ITC had granted 21 non-exclusive, non-transferable, perpetual, worldwide, royalty-bearing licenses to use certain TDMA patents. We also anticipate that we will be able to generate significant revenue from the licensing of patents for 3G applications. Based on the standards as adopted, we believe that we have a number of patents that are essential to the implementation of all of the technology modes incorporated in the existing 3G standards. We also expect that many of our patents or to be issued patents will be commercially important in the actual product implementation. We have recently initiated active discussions on a worldwide basis regarding the licensing of our CDMA patents. Our current license agreements with Nokia, Siemens and Qualcomm do include rights under certain of our patents to manufacture and sell products compliant with 3G standards, with some limitations. The Nokia Agreement is paid-up, generally, through the period during which Nokia and InterDigital are engaged in the 3G development project. (See "- Strategic Engineering Services"). After such period, a structure is provided for determining future royalty payments. All of our current essential patents for 3G standards are included under the Nokia Agreement. The Siemens and Qualcomm agreements are fully paid-up with regard to the rights granted, which includes certain rights as to 3G products. The Siemens agreement does not include any rights under patents issuing from patent applications filed after December 15, 1999. The Qualcomm license agreement excludes, among other things, any rights under our patents as regards TDMA standards, any rights under our patent applications filed after March 7, 1995, as well as patents relating to cellular overlay and interference cancellation. Based on these limitations, neither the Siemens nor the Qualcomm agreement provides rights under all the ITC patents which we believed to be essential to 3G, or all of the inventions which we believe will be essential and which are contained in pending patent applications. The Qualcomm license agreement grants Qualcomm the paid-up right to grant sublicenses under certain of our patents to Qualcomm's customers. In high technology fields characterized by rapid change and engineering distinctions, the validity and value of patents are often subject to complex legal and factual challenges and other uncertainties. Accordingly, ITC's patent claims are subject to uncertainties which are typical of patent enforcement generally. If any third party successfully asserts that certain of our patent claims are not valid or do not cover their products, or if the 3G standards were to change in a material manner, or if products are implemented in a way such that patents that we believe to be commercially important are not infringed, InterDigital's licensing potential and revenues could be adversely affected. The cost of enforcing and protecting the patent portfolio can be significant. In that regard, we are currently in litigation with Ericsson, Inc., which is seeking the court's declaration that Ericsson's products do not infringe ITC's United States TDMA patents, that certain of ITC's United States TDMA patents are invalid and that certain of ITC's United States TDMA patents are unenforceable. Ericsson has also asserted claims of tortious interference with contractual and business relations, defamation and commercial disparagement, violation of ss. 43(A) of the Lanham Act, breach of contract directly or as a third-party beneficiary, and fraud and negligent misrepresentation for which Ericsson seeks an unspecified amount of actual damages, costs and attorneys' fees. We are vigorously contesting each of Ericsson's allegations. In addition, ITC has counterclaimed against Ericsson alleging that Ericsson is willfully infringing certain United States TDMA patents owned by ITC. ITC seeks a permanent injunction against Ericsson's infringement of these patents, and an unspecified amount of actual and exemplary damages, costs and attorneys' fees. (See Item 3. "Legal Proceedings. Ericsson".) In addition to patent licensing, we have also been actively engaged since 1994 in the licensing of know-how both to companies with whom we have had strategic relationships (including alliance partners) and to other companies. Our initial technology transfer program involved our proprietary B-CDMA technology, a wideband CDMA technology 9 initially adapted for WLL applications but with mobile capability. In 1994, we entered into technology licensing arrangement with Siemens AG under which Siemens was provided access and use, on a royalty-bearing basis, to our developed and to-be-developed B-CDMA technology. In January 1996, we added Samsung as a licensee both to our B-CDMA technology and our UltraPhone product know-how. Alcatel Espana signed a license with us in 1998 for B-CDMA technology. In 1999, both Siemens and Alcatel made corporate decisions not to invest further in the development of proprietary B- CDMA technology for fixed wireless applications and to focus their energies on the 3G market. In 1999, we signed a technology transfer and licensing agreement with Nokia for TDD technology. (See "- Business Activities. Strategic Engineering Services.") Since 1992, we have generated approximately $282 million in patent royalty and technology licensing revenue.

We have participated actively in the 3G standards development process, contributing a significant number of proposed concepts and methodologies to the standards bodies in Europe and the United States. A number of our contributions have been adopted and are now part of the standard which will be implemented worldwide. Mr. Brian Kiernan, one of our Senior Vice Presidents, is the Chair of a task force under the Institute of Electrical and Electronic Engineers that develops standards for wireless access systems. In addition, we are members of various standards bodies including the ITU, 3G Partnership Project (3GPP), Telecommunications Industries Association (TIA), Electronics Industries Association (EIA), European Telecommunications Standards Institute (ETSI), American National Standards Institute (ANSI), and Association of Radio Industries and Businesses (ARIB). Employees; Research & Development Resources and Expenses As of March 1, 2000, InterDigital had approximately 191 full-time employees. In addition, we use the services of consultants and part-time employees. None of InterDigital's employees are represented by a collective bargaining unit. A breakdown of InterDigital's full-time employees by functional area is as follows: NUMBER OF FUNCTIONAL AREA EMPLOYEES --------------- --------- Sales and Marketing 5 Customer Support 10 Manufacturing 10 Research and Development 126 Patent Licensing 11 Corporate and Administration 29 --- Total 191 === As of March 1, 2000, InterDigital employed approximately 126 people whose primary responsibilities are 3G technology development, and additionally utilizes the efforts of outside engineering resources as well as engineering contributions from Nokia. Further development of InterDigital's technologies is expected to require additional technical and administrative support, as well as additional marketing resources and higher levels of sustained efforts for the next several years. We have undertaken an aggressive effort to increase and retain our engineering resources. The recruitment of personnel with technical expertise in wireless communications technology development is highly selective and competitive. In addition to recruiting high quality engineers, we intend to attempt to satisfy our increasing need for engineering resources through, among other things, consulting services and further strategic relationships.

Prior to joining InterDigital, from 1987 to 1996, Mr. Merritt held a variety of positions in the Legal Department for Long Island Lighting Company, a New York electric and gas utility company, the last of which was Assistant General Counsel responsible for all company litigation and corporate matters. Mr. Merritt was also General Counsel to that company's power plant operation subsidiary, Dynamic Energy Services Corporation, since 1995. Charles "Rip" Tilden was named Executive Vice President-Communications, Investor Relations and Strategic Planning of InterDigital in March 1998. Prior to that, he held the positions of Senior Vice President from May 1997 and Vice President from November 1996 until May 1997. Before joining InterDigital, Mr. Tilden served as Vice President, Corporate Affairs at Alco Standard Corporation in Wayne, PA, an office products and paper distribution company, since December 1994. Before moving to Alco Standard, Mr. Tilden was Vice President, Communications for GenCorp in Akron, OH, an aerospace defense, automotive and polymer products company from 1988 to 1994. InterDigital's Executive Officers are elected to the offices set forth above to hold office until their successors are duly elected and have qualified. All of such persons are parties to agreements which provide severance pay benefits, among other things, in certain events of terminations of employment. These agreements generally provide for the payment of severance up to a maximum of one year's salary and up to a maximum of one year's continuation of medical and dental benefits. In addition, in the event of a termination or resignation within one year following a change of control, which is defined as the acquisition, including by merger or consolidations, or by the issuance by InterDigital of its securities, by one or more persons in one transaction or a series of related transactions, of more than fifty percent (50%) of the voting power represented by the outstanding stock of InterDigital, the executive would generally receive two years of salary and the immediate vesting of all restricted stock and stock options. 12 Risk Factors Item 1, "Business" and Item 7, "Management's Discussion and Analysis" contained within this Annual Report on Form 10-K contain forward-looking statements reflecting, among other things, (i) our strategic objectives; (ii) analysts', industry observers' and experts' beliefs and forecasts as to the market for wireless products and services, 3G market growth, and the timing of market development; and (iii) our current beliefs and expectations as to 3G product and technological capability, the successful development and the applications for our technology and potential products, 3G markets, demand for 3G products, timing of 3G market development, applicability of standards, preferences of service providers, our ability to enter into new business relationships, enter into new licenses, bring 3G products to market, and deliver engineering services, our ability to derive revenues from our patents, our competition and competitive advantages, and the effectiveness of our Year 2000 compliance. Words such as "should", "likely to", "expect", "forecast", "believe", "strategy", "intend", "plan", "targeting", "anticipate", "project", and "may seek", variations of such words, and words with similar meaning or connotations are intended to identify such forward-looking statements. Such statements are subject to risks and uncertainties. We caution readers that important factors in some cases have affected and, in the future, could materially affect actual results and cause actual results to differ materially from the results expressed in any such forward looking statement. You should not place undue reliance on these forward-looking statements, which apply on or as of the date of this report. Certain of these risks and uncertainties are described in greater detail below. It should be noted that risks described as affecting one forward looking statement may affect other forward looking statements. In addition, other factors may exist that are not detailed below or that are not fully known to us at this time. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise. Our Strategy Is Forward-Looking in Nature Our strategy is forward-looking in nature and, as such, is inherently subject to risks and uncertainties. Many factors, including the other Risk Factors detailed below, could affect our potential revenues and profitability and our ability to achieve our objective to become a premier provider of innovative technology for advanced wireless communications products. For example, our plans to place our strategic emphasis on 3G technology and products, to devote substantial resources to the development of TDD and FDD technology, to market our FDD and TDD components (including system-on-a-chip), our capabilities and technology content, and generate sufficient revenues from associated engineering services could be affected by shifts in our strategy, the ability to generate sufficient revenues to support our development activities (which could itself be affected by numerous factors including, without limitation, the ability to secure new and enforce existing license agreements and the ability to enter into new strategic relationships), unanticipated development costs, difficulties or delays in engineering projects, failure to successfully enter into additional strategic relationships, our ability to successfully and timely complete engineering projects, our ability and the ability of our partners to successfully market and sell 3G products, our ability to hire or retain adequate personnel, Nokia's exercise of its rights to terminate the development project for convenience, and the failure of the 3G market to materialize in the manner or time frame anticipated. Analyst and Market Predictions are Forward-Looking in Nature Our market predictions, as well as, analyst, industry observer and expert predictions described in "-Wireless Telecommunications Industry Overview" above, are forward looking in nature and, as such, are inherently subject to risks and uncertainties. Many factors could affect these predictions including, but not limited to, the validity of their and our assumptions, economic conditions, customer buying patterns, timeliness of equipment development, pricing of 3G products, continued growth in telecommunications services that would be delivered on 3G devices, and availability of capital for infrastructure improvements. Also, the 3G market may not develop at the rate or the pace that we or they predict. 13 Our Future Operating Results are Uncertain and Likely to Fluctuate Although we have experienced an increase in both revenues and profitability over the last two years, we have experienced and may continue to experience quarterly variability in operating results. It is particularly difficult to predict the timing or amount of our strategic partner or license revenues because (i) we may not be able to enter into additional strategic partnerships or license agreements, either at all or on acceptable terms; (ii) the negotiating cycles for partnership and licensing agreements are lengthy and variable, typically ranging between 6 months and 2 years prior to signing; (iii) the markets for our technologies are subject to rapid technological changes; (iv) our markets are subject to increased competition from other products and technologies and announcements of new products and technologies by our competitors; (v) we may experience delays or difficulties in our technology development efforts; and (vi) the strength of our patent portfolio could be weakened through patents being declared invalid, design-arounds, changes to the standards, and adverse court decisions; and (vii) we may be unable to adequately protect our proprietary rights. Nevertheless, we base our decisions regarding our operating expenses on a combination of current cash balances and anticipated revenue trends. Because the base level of many of our expenses are relatively fixed, a delay in recognizing revenue from a limited number of licenses transactions could cause our operating results to vary significantly from quarter to quarter and could result in operating losses. To the extent these expenses are not followed by increased revenues, our operating results will suffer. In addition, increased expenses which could result from factors such as increased hiring and retention costs or actions designed to keep pace with technology and product market targets could adversely impact near-term profitability targets. We Rely Heavily on our Relationships with Third Parties We rely heavily on our relationship with Nokia as part of our 3G strategy. Our development agreement with Nokia is terminable. In the event Nokia were to terminate our development agreement, we may, depending upon the circumstances, be compelled to terminate the development project. Following any such termination, our position as a 3G technology developer could be weakened which, in turn, could adversely affect our ability to enter into new relationships for technology development. The successful achievement of our objectives is also partially dependent on our ability to enter into new strategic partnerships, including a relationship with a semi-conductor manufacturer. Our failure to enter into such additional relationships, either on acceptable terms or at all, could impair our ability to introduce our technology and resulting products. In addition, delays in entering into such relationships could cause us to miss critical market windows. (See "-Our Markets are Subject to Rapid Technological Change".) This, in turn, may adversely affect our future revenue streams. Further, our royalty revenue depends in part on the performance of our licensees to sell products. Their ability to deliver such products is outside of our control. We Have Substantial Global Competition Competition in the wireless telecommunications industry is intense. We cannot assure you that we will be able to successfully compete, or that our competitors will not develop new technologies and products that are more commercially effective than our own. We face competition from companies providing services comparable to ours. We also face competition from the in-house development teams at telecommunication equipment suppliers. Many of our competitors are substantially larger than we are, and have financial, technical, marketing, sales, and distribution resources greater than ours. In addition, our customers may face competition from other telecommunication equipment providers. It is also possible that new competitors may enter the market. Further, our ability to derive revenues from the licensing of technology will depend in part on the successful and timely development of our technologies and in part on our ability to gain additional customers. Our competitive position can be compromised by the introduction of superior technology or our delay in (or a competitor's more timely introduction of) relevant technology. (See "- Our Markets are Subject to Rapid Technological Change".) In order to generate revenues and profits from sales of ASIC products, we must continue to make substantial investments and technological innovations, which are subject to a number of risks and uncertainties. Other digital wireless 14 technologies, particularly cdma2000 and enhanced data rates for global evolution (EDGE), are expected to be competitive with our own form of wideband CDMA and we cannot assure you that our technology will be selected by wireless service providers for their networks. (See "- We Need to Effect Further Technology & Product Development".) In addition, our semiconductor partner must be able to provide competitively priced products, and possess adequate manufacturing and distribution networks. We Need to Effect Further Technology & Product Development We may experience technical, financial or other difficulties or delays related to the further development of our technology. Delays can be costly, and there can be no assurance that our development effort will ultimately be successful. Further, if such engineering efforts are not successful or delays are serious, our existing and potential strategic relationships could suffer or these strategic partners could be hampered in their marketing efforts of products containing our technologies. This means that we could experience reduced royalty revenues or lower royalty revenues on such organizations' products containing our technology, or that we could miss a critical market window. (See "- Our Markets are Subject to Rapid Technological Change".) Further, if we do not meet the material obligations under our contracts with our partners, the partner could terminate the relationship and/or hold us liable for breach. (See "-We Rely Heavily on our Relationships with Third Parties".) Moreover, our technologies are in the development stage, and have not been fully tested in commercial use. It is possible that they may not perform as expected. Our Markets are Subject to Rapid Technological Change The entire communications market in which we compete is characterized by rapid technological change, frequent product introductions and evolving domestic and international industry standards. Existing technology and products become obsolete and unmarketable when products using new technologies are introduced and new industry standards emerge. As a result, marketability and the potential life cycles of the products and technologies that we are developing can not be assured and are difficult to estimate. In addition, new industry standards, falling prices or technology changes may render the products and/or technologies obsolete or non-competitive. To be successful, we must continue to develop new products and technologies that successfully respond to such changes. We may not be able to form strategic relationships, either at all or on acceptable terms, to enable us to develop such new products and technologies. (See "-We Rely Heavily on our Relationships with Third Parties".) Even if we do, we may not be able to introduce such products or technologies successfully in a timely manner. Missing a critical market window could reduce or eliminate our ability to capitalize on the technology and products as to which the window applies. These efforts will require continued significant investment in research and development. We cannot be sure that we will have sufficient resources to make such investments, that we will be able to make the technological advances necessary to achieve these goals, or that the costs of the acquired efforts will be acceptable. (See "-We Need to Effect Further Technology & Product Development".) Our business, financial condition and operating results could be materially adversely affected if we are unable to respond to the need for technological change or if these products or technologies do not achieve market acceptance when released. (See "-Our Future Operating Results are Uncertain and Likely to Fluctuate".) The Applicability of Our Patents to Industry Standards is Subject to Change The ITU has developed a standard for 3G products known as IMT-2000. A number of our contributions have been adopted and are now part of the standard. However, we expect that the standard will be refined as equipment designs for 3G systems are finalized. Material changes to the 3G standard could adversely affect the applicability of our patents to the standard. If the wireless industry adopts 3G standards which are incompatible with our technology or determines not to rely on our intellectual property, this could have a material adverse effect on our business, results of operations, liquidity and financial position. 15 In addition, we believe that, in many instances, licenses for certain of ITC's TDMA patents are required in order for third parties to manufacture and sell digital cellular products in compliance with the IS-54-B/IS-136 Standard, the Global System for Mobile Communication, the Pan Asian Digital Cellular Standard, Digital Enhanced Cordless Telephone and Personal Handyphone System. While we intend to vigorously enforce and protect our intellectual property position against any infringement, we cannot assure you that the validity of our relevant patents will be maintained, or that any of our patents will be determined to be applicable to any standard. Such a finding would impair our licensing opportunities as to those patents, which would, in turn, adversely affect our receipt of future revenues. (See "-We Rely on and May Be Unable to Adequately Protect Our Proprietary Rights".) We Rely On and May Be Unable to Adequately Protect Our Intellectual Property Rights Our business opportunities substantially depend upon the development of know-how and patent inventions. To protect these rights, we rely primarily on a combination of patent laws, confidentiality agreements with employees and third parties, and protective contractual provisions. Despite our efforts to protect our proprietary rights, unauthorized parties may copy aspects of our technology and information that we regard as proprietary. Other parties may breach confidentiality agreements and other protective contracts into which we have entered. We may not have adequate remedies in the event of such breach. Further, we cannot assure you that the pending patent applications will be granted, or that our existing or new patents will provide adequate protection or coverage. (See "-The Applicability of Our Patents to Industry Standards is Subject to Change".) In addition, the cost of defending our intellectual property has been and may continue to be significant. Moreover, third parties could circumvent ITC's patents through design changes. Any of these events could adversely affect our prospects for realizing future income. (See "-We Could Experience Unfavorable Results in Patent Litigation" below and "-Our Operating Results are Uncertain and Likely to Fluctuate" above.) From time to time, certain companies may also assert that their patent, copyright and other intellectual property rights are also important to the industry or to us. In that regard, from time to time third parties provide us with copies of their patents relating to digital wireless technologies and offer licenses to such technologies. We in turn evaluate such patents and the advisability of obtaining such licenses. If any of our products were found to infringe on protected technology, we could be required to redesign such products, license such technology, and/or pay damages to the infringed party. If we are unable to license protected technology used in our products and/or if we cannot economically redesign such products, we could be prohibited from marketing such products. We Could Experience Unfavorable Results in Patent Litigation Together with ITC, we are currently in litigation with Ericsson over certain of ITC's patents. During the course of such litigation (or in a future yet unidentified and unfiled litigation), certain of ITC's key patents could be declared invalid or not infringed. This could adversely affect our competitive position and our ability to enter into additional licensing agreements and to realize licensing revenues from current licensees. (See, Item 3. "Legal Proceedings".) Our License Agreements Contain Provisions which Could Impair Our Ability to Realize Licensing Revenues Certain of our licenses contain "most favored nations" and other provisions, applied on a going forward basis only, which could, in certain events, cause the licensee's obligation to pay royalties to us to be terminated or suspended for an indefinite period, with or without the accrual of the royalty obligation. In addition, certain of our licensees had, in the past, stated, among other things, that the outcome of a prior litigation over ITC's patents materially impacted the royalties due under their license agreements. While we believe that these positions have been meritless, similar positions could be asserted in the event that a licensee's obligation to pay royalties to us in the future is either terminated or indefinitely suspended or in the event that ITC's patents are held invalid or unenforceable or this position could be found to have merit. Such positions 16 taken could interfere with ITC's ability to secure new licenses or to generate recurring licensing revenue under the existing agreements. In addition, ITC may have to incur expenses and suffer further delays to mediate, arbitrate and/or litigate such assertions, with no assurance of ultimate success. ITC's licensing opportunities are also affected by the increasing concentration of the wireless industry, particularly as to infrastructure, which results in a substantial portion of the licensing opportunities being concentrated in a small number of non-licensed manufacturers, many of whom are generally opposing the validity of ITC's patents in multiple forums. We Depend on Sufficient Engineering Resources Competition for qualified and talented individuals with engineering experience in emerging technologies, like wideband CDMA, is intense. Further, none of the persons that we currently employ are parties to agreements that require them to provide services to us for a minimum period of time. Our success and ability to enter into additional strategic or other relationships may depend on our ability to attract and retain a significant number of talented and qualified technical personnel; and there can be no assurance that we will be able to do so. The failure to attract and retain highly qualified personnel could interfere with our ability to undertake additional technology and product development efforts as well as our ability to meet our strategic objectives. Year 2000 Problems May Cause Engineering Difficulties or Delays Although we have passed the January 1, 2000 and February 29, 2000 critical dates for experiencing Year 2000 related failures without significant problems and we are not aware of any impending failures, it is possible that the full impact of the date changes has not been fully recognized. For example, it is possible that Year 2000 related issues may arise in the future, either because they have not yet become apparent to us or because future date changes trigger failures. In addition, we could still be negatively affected if third parties upon whom we rely are adversely affected by the Year 2000 or similar issues. We Face Risks From Our International Operations We conduct business in foreign jurisdictions and with foreign organizations. In doing so, we are subject to the effects of government regulations, tariffs and other applicable trade barriers, currency control regulations, political instability, potentially adverse tax consequences, inability to enforce contractual commitments abroad, and general delays in remittance and difficulties of collecting foreign payments, among other things. We Face Risks From Economic Conditions We and our customers face risks from economic conditions generally which affect, among other things, the ability and willingness of companies to invest in technological and product development, our need for working capital, and our revenue recognition. 17 Item 2. PROPERTIES InterDigital owns one facility, subject to a mortgage, with an aggregate of approximately 50,000 square feet of office, development, warehousing and assembly facilities in King of Prussia, Pennsylvania. In December 1996, InterDigital entered into a five-year lease for approximately 67,000 square feet of office and development facilities in Melville, New York. These facilities are the locations for our wideband CDMA development activities. Item 3. LEGAL PROCEEDINGS Ericsson In September 1993, ITC filed a patent infringement action against Ericsson GE Mobile Communications, Inc. ("Ericsson GE"), its Swedish parent, Telefonaktieboleget LM Ericsson ("LM Ericsson") and Ericsson Radio Systems, Inc. ("Ericsson Radio"), in the United States District Court for the Eastern District of Virginia (the "Ericsson action") which was subsequently transferred to the United States District Court for the Northern District of Texas. The Ericsson action seeks a jury's determination that in making, selling, or using, and/or in participating in the making, selling or using of digital wireless telephone systems and/or related mobile stations, Ericsson has infringed, contributed to the infringement of and/or induced the infringement of eight patents from ITC's patent portfolio. The Ericsson action also seeks an injunction against Ericsson from infringement and seeks unspecified damages based upon the Court's determination of what constitutes a reasonable royalty for infringement, royalties, costs and attorneys' fees. Ericsson GE filed an answer to the Virginia action in which it denied the allegations of the complaint and asserted a Counterclaim seeking a Declaratory Judgement that the asserted patents are either invalid or not infringed. On the same day that ITC filed the Ericsson action in Virginia, two of the Ericsson Defendants, Ericsson Radio and Ericsson GE, filed a lawsuit against InterDigital and ITC in the United States District Court for the Northern District of Texas (the "Texas action"). The Texas action, which involves the same patents that are the subject of the Ericsson action, seeks the court's declaration that Ericsson's products do not infringe ITC's patents, that ITC's patents, are invalid and that ITC's patents are unenforceable. The Texas action also seeks judgment against InterDigital and ITC for tortious interference with contractual and business relations, defamation and commercial disparagement, Lanham Act violations. The Ericsson action and the Texas action have been consolidated. ITC agreed to the dismissal without prejudice of LM Ericsson. In December 1997, Ericsson Inc., the successor to Ericsson GE and Ericsson Radio, filed an action against ITC in the United States District Court for the northern District of Texas (the "1997 Texas action") seeking the court's declaration that Ericsson Inc.'s products do not infringe two patents issued to InterDigital earlier in 1997 as continuations of certain patents at issue in the Texas action. Later that month, Ericsson Inc. filed an amended Complaint seeking to include these two new patents in the Texas action in an effort to consolidate the two cases. In January 1998, both Ericsson Inc. and InterDigital and ITC filed motions requesting that Ericsson Inc.'s amended Complaint be allowed and that the 1997 Texas action be dismissed, to which the Court agreed. In 1998, Ericsson Inc. filed a Motion for Partial Summary Judgment, which was denied by the Court in early 1999. Also in 1998, the United States District Court for the Northern District of Texas granted InterDigital's Motion to amend its Counterclaim by adding four additional patents. During the third quarter of 1999, Ericsson Inc. filed for leave to file an additional Amended Complaint to add causes of action for breach of contract and fraud and negligent misrepresentation. The Court granted Ericsson's request. Fact discovery has been substantially concluded. The "Markman" hearing is scheduled to take place in April, 2000, where a Special Master will make recommendations to the Court as to the meaning of certain terms contained in the patents. InterDigital and ITC intend to vigorously defend the Texas action. However, if any of ITC's patents are held invalid, ITC's licensing opportunities and collection of royalty revenues could be materially and adversely affected. 18 Product-Based Suit On October 27, 1999, Cavalier Technologies and Consultants Ltd. ("Cavalier") filed suit against us in the United States District Court of the Eastern District of Pennsylvania for breach of contract to team to supply and for breach of contract to supply UltraPhone systems in Kenya and for fraudulent representations as to our future plans for the UltraPhone business. Concurrently with the filing of its Complaint, Cavalier filed a request for a Temporary Restraining Order and a Motion for a Preliminary Injunction to prevent us from shipping any of our remaining inventory of UltraPhone equipment to other customers. The Court denied the TRO application, and scheduled a preliminary injunction hearing. In December, 1999, the Court issued a bench ruling denying Cavalier's motion for a preliminary injunction on the grounds that Cavalier had failed to demonstrate irreparable harm. Cavalier continues to seek damages and injunctive relief. We anticipate that the trial will be set for later in 2000. We have asserted a damages counterclaim for past due balances. Other ITC has filed patent applications in numerous foreign countries. ITC is and expects from time to time to be subject to challenges with respect to its patents and patent applications in foreign countries. ITC intends to vigorously defend its patents. However, if any of ITC's patents or applications are revoked, ITC's patent licensing opportunities in the relevant foreign countries, and possibly in other countries, could be materially and adversely affected. In addition to litigation associated with patent enforcement and licensing activities and the litigation described above, InterDigital is a party to certain other legal actions arising in the ordinary course of its business. Based upon information presently available to InterDigital, InterDigital believes that the ultimate outcome of these other actions will not materially affect InterDigital. Item 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS None. 19 PART II Item 5. MARKET FOR COMPANY'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS The following table sets forth the range of the high and low sales prices of InterDigital's Common Stock as reported by the American Stock Exchange. High Low ---- --- 1999 First Quarter 6 15/16 4 1/8 Second Quarter 5 3/4 4 1/16 Third Quarter 6 3/4 4 1/4 Fourth Quarter 82 5 5/16 High Low ---- --- 1998 First Quater 6 3/16 2 9/16 Second Quarter 7 7/16 5 3/16 Third Quarter 5 7/8 2 11/16 Fourth Quarter 6 7/8 3 As of March 24, 2000, there were approximately 1,860 holders of record of our Common Stock. We have not paid cash dividends on our Common Stock since inception. It is anticipated that, in the foreseeable future, no cash dividends will be paid on our Common Stock and any cash otherwise available for such dividends will be reinvested in our business. The payment of cash dividends will depend on our earnings, the prior dividend requirements on our remaining series of Preferred Stock and other Preferred Stock which may be issued in the future, our capital requirements and other factors considered relevant by our Board of Directors. Changes in Capitalization In March 2000, we amended our Shareholder Rights Plan, originally adopted in December 1996, in a number of respects. Under the Plan, a distribution of one right for each outstanding common share of the Company has been made. Each right entitles the shareholder, subject to the terms of the Plan, to purchase one one-thousandth of a share of Series B Junior Participating Preferred Stock at a purchase price of $250 per share unit, subject to adjustment. Initially, the rights attach to certificates representing shares of outstanding common stock, and no separate rights certificates are distributed. The rights will only separate from the common stock after the "Distribution Date", which will occur upon (i) the earlier of (A) ten business days following the earliest of the date of a public announcement, the date the Company first learns of such acquisition, or, in certain limited circumstances, the date of such acquisition, that a person or group of affiliated or associated persons (other than the Company, any of its subsidiaries or any of their employee benefit plans) (such person or group being defined as an "Acquiring Person") has acquired, obtained the right to acquire or otherwise obtained beneficial ownership (in limited circumstances, beneficial ownership can be deemed if such person or group possesses voting power over shares arising from a proxy, even if revocable, given in response to a proxy or consent solicited by or on behalf of such person or group and in furtherance of such person's or group's publicly announced intention to acquire control over the Company or 20 over all or substantially all of the assets or stock of the Company) of 10% or more of the then outstanding shares of Company Common Stock; (B) ten business days following the commencement of a tender offer or exchange offer that would result in a person or group beneficially owning 10% or more of the then outstanding shares of Company Common Stock; and (C) ten business days after a non-exempt person or group publicly announces an intent to acquire control over the Company and proposes in a proxy or consent solicitation to elect such a number of directors which, if elected, would represent a majority of the directors when compared with the Independent Directors continuing to serve on the Board of Company, or (ii) such later date as may be determined by action of a majority of the Independent Directors of the Board prior to the occurrence of any event specified in (i) above. The determination of beneficial ownership generally excludes options to purchase shares and shares acquired from the Company pursuant to stock-based plans for employees and directors. In general, in the event that the Company is acquired in a merger or other business combination interaction, each holder of a right will have the right to receive, upon exercise, units of Preferred Stock (or, in certain circumstances, Company Common Stock, cash, property, or other securities of Company) having a current market value equal to two times the exercise price of the Right. The full text of the March 2000 amendments is set forth as Amendment No. 3 to the Shareholder Rights Plan, which is attached as Exhibit 4.4 hereto.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW The following discussion should be read in conjunction with the Selected Consolidated Financial Data, and the Consolidated Financial Statements and notes thereto, contained elsewhere in this document. We commenced operations in 1972. Since that time, we have been primarily engaged in research and development activities related to wireless digital communications technology, principally TDMA and CDMA technologies. We have established a substantial and significant library of patents and technology know-how related to such technologies. Through 1999, we were also engaged in the development, marketing, sales and servicing of WLL equipment utilizing our technology. We developed, marketed and sold a TDMA-based WLL system trademarked the "UltraPhone(R)" system. We also developed a CDMA-based WLL system, trademarked the "Truelink(TM)" system, which utilized wideband CDMA technology. As part of our WLL development and marketing efforts, we entered into strategic alliance agreements with Siemens AG (in 1994), Samsung Electronics Co., Ltd. (in 1996), and Alcatel Espana (in 1998) involving the Company's proprietary B-CDMA WLL technology. In the first half of 1999, we made a major shift in our business strategy by dedicating our resources into the emerging 3G market. As part of that undertaking, we decided to discontinue the further development and manufacture of WLL products. The decision to move away from the manufacture of WLL products was further driven by intensified product and price competition in the WLL market, and a significant decline in demand worldwide for WLL systems. As part of our shift, we sought to enter into arrangements with key equipment providers involving 3G technology and products. The proposed 3G technologies incorporate wideband CDMA protocols as well as other CDMA and TDMA technologies. Industry analysts project that the first 3G products and services will be introduced in Japan in 2001, with services being offered in other parts of Asia, Europe and North America throughout this decade. The study group for International Telecommunications Union formally adopted the 3G standards in 1999, solidifying wideband CDMA as one of the fundamental technologies for 3G. Executing on our business plan, we entered into a strategic engineering relationship with Nokia in 1999 involving the development of high data-rate technology. As part of the Nokia agreement, we will retain ownership rights over the technology we develop for Nokia. Also, included in the agreement were certain TDMA and CDMA licenses which are paid up generally through the project period. The agreement also provides a structure for determining patent royalty payments thereafter. In 1999, we also initiated a self-funded research and development effort to develop building blocks for FDD technology, another component of the wideband CDMA protocols included in the 3G Standard. The FDD program builds off of our extensive B-CDMA development efforts. We plan to market system-on-a-chip ASICs and components related to our FDD and TDD technology to equipment producers worldwide. We also plan to generate revenues from the licensing of the TDD and FDD technologies and patents to third parties, as well as providing specialized engineering services to equipment producers centered around these technologies. Our ability to derive future revenues will be affected by other factors detailed elsewhere in this Annual Report. (See "Item 1. Business. Risk Factors" below.) As a result of the decline in the rural fixed and wireless access market and the anticipated emergence of 3G standards in 1999, we ceased further development and sales activities with regard to WLL equipment. In 1999, Siemens withdrew from our B-CDMA development project. In April 1999, Alcatel informed us that it was also withdrawing from our B-CDMA development project, on the same basis. As a result of Alcatel's and Siemens' decisions as well as our own assessment of the WLL market, we decided to reduce our resource commitment to B-CDMA development. In 1999, we also decided to discontinue the manufacture of the UltraPhone system. We sustained significant losses over the life of the UltraPhone Product line due to our inability to achieve sufficient sales volumes and the need to continue 23 to consistently upgrade and re-engineer the product, at significant expense. We expect final shipments will be completed by June 2000 at which point we expect to exit the business. Going forward over the course of the next few years, we expect the variability in our revenues and, consequently, our cash flow to continue due to the timing and amount of sales by our TDMA and CDMA licensees. We expect to continue to experience considerable fluctuations in quarterly and annual operating results in the future due to variations in the amount and timing of recognition of TDMA and CDMA license, royalty and development fees. (See Item 1. "Business. Risk Factors".) FINANCIAL POSITION, LIQUIDITY AND CAPITAL REQUIREMENTS We generated positive cash flows from operating activities of $24.2 million in 1999 compared to $30.1 million in 1998. The decrease principally resulted from lower net income levels attained in 1999. Net cash flows used in investing activities increased to $35.5 million in 1999 from $27.5 million in 1998. This increase was due mainly to a higher level of additional investment of funds in short-term, highly liquid securities ($36.3 million in 1999 versus $24.2 million in 1998) offset in part by a 1999 reduction in long-term deposits. In addition, investments in property and equipment and patents were $2.9 million in 1999 as compared to $3.6 million in 1998. During 1999, net cash provided by financing activities was $6.1 million as compared to $0.4 million used in 1998. The increase in 1999 primarily resulted from net proceeds of $12.4 million related to option and warrant exercises and our employee stock purchase plan. This was partially offset by the use of $5.4 million to repurchase approximately 1.0 million common shares under a share repurchase program. As of December 31, 1999, we had $83.1 million of cash, cash equivalents and short-term investments, compared to $52.3 million as of December 31, 1998. Our working capital increased by $40.7 million to $95.5 million at December 31, 1999 from $54.8 million at December 31, 1998 mainly as a result of the receipt of cash from licensing agreements as well as reductions in deferred revenues and current payables. We are capable of supporting our operating requirements during 2000 through internally generated funds. Should the need arise to fund new development activities, contingency resolution, external growth activities or other matters, we may seek financing through bank facilities or the sale of debt or equity securities. We believe that our investment in inventories at December 31, 1999 is realizable based on expected selling prices and order volumes. Property and equipment are currently being utilized in our on-going business activities, and we believe that no additional write-downs are required at this time due to lack of use or technological obsolescence. With respect to other assets, we believe that the value of our patents is at least equal to the value included in the December 31, 1999 balance sheet. RESULTS OF OPERATIONS 1999 Compared With 1998 Revenues Revenues in 1999 totaled $70.7 million, compared to $99.2 million in 1998. The decrease relates to a lower amount of licensing revenue. In 1999, InterDigital recognized $42.8 million in new licenses, $14.0 million in engineering services for strategic partners, $9.5 million from recurring royalties and $4.4 million in product revenues. In 1998, new licensee revenue was $83.5 million, strategic partner revenue was $8.0 million, recurring royalties were approximately $1 million and product revenues were $6.8 million. 24 Cost of Product Cost of product revenues decreased 67% to $5.9 million from $17.6 million in 1998. The decrease reflects decreased product sales as well as the impact of a write-down of inventory of $7.9 million in 1998. We experienced negative gross margins in both years as there were insufficient product sales to absorb manufacturing overhead. Other Operating Expenses Other operating expenses include sales and marketing expenses, general and administrative expenses, patents administration, and development expenses. Sales and marketing expenses decreased 6% to $3.6 million during 1999 as compared to $3.9 million in 1998. The decrease is primarily due to decreased sales commissions and decreased marketing activity for the UltraPhone product. General and administrative expenses for 1999 increased 43% to $7.8 million from $5.4 million in 1998 due in part to staffing level changes and higher compensation costs associated with restricted stock grants. Patents administration and licensing costs decreased 52% to $5.3 million as compared to $11.1 million in 1998. We incurred less costs such as commissions and other expenses related to our activities supporting our licensing program, and recovered certain expenses related to an ongoing patent litigation with Ericsson. In February of 2000, InterDigital and its insurers defined the method, timing and limitations of reimbursement for covered litigation expenses. Development costs increased 19% to $20.5 million from $17.2 million in 1998. This increase reflects the ramp up of development costs associated with launching the 3G projects. Repositioning In the second quarter of 1999, we recorded a pre-tax repositioning charge of $1.2 million in connection with a change in our strategy from sales and development of wireless local loop products to technology development for advanced wireless applications. This action was taken after assessing our long term business prospects associated with continued investment in the development of wireless local loop systems. The repositioning charge included costs associated with workforce reductions (approximately 27 employees) and asset impairment charges related to wireless local loop development equipment. The components of the repositioning charge included severance and other benefit costs of $0.4 million, all of which were paid in 1999, and asset impairment charges of $0.8 million for fixed assets associated with wireless local loop activities. Management's efforts with respect to this plan are substantially complete. Other Income and Expense Interest Income for 1999 was $3.9 million as compared to $2.6 million in 1998 as a result of higher average invested cash in 1999 as compared to 1998. Interest expense was $0.3 million in 1999 compared to $0.4 million in 1998 due to lower overall debt in 1999 as compared to 1998. 1998 Compared With 1997 Revenues. Revenues in 1998 increased 99% to $99.2 million from $49.8 million in 1997 due to the significant increase in licensing and strategic partner revenue. In 1998, licensing and strategic partner revenue included $83.5 million from new and existing license agreements, approximately $1 million in recurring royalties, $4.6 million from Alcatel, and $3.4 million from Samsung. In 1997, licensing and strategic partner revenue included $1.6 million in recurring royalties, the final $1.6 million of strategic partner revenue from Siemens, and $2.8 million from Samsung. 25 Cost of Product Cost of product decreased in 1998 to $17.6 million from $41.9 million in 1997. The decrease is directly related to the decrease in product sales. In 1998, there were insufficient product sales to absorb manufacturing overhead and increases in inventory reserves resulting in a negative gross margin of 160.4% as compared to a positive gross margin of 4.4% in 1997. In 1998, InterDigital recorded charges totaling $7.9 million to reduce the carrying value of its inventory of UltraPhone components to its net realizable value due to excess inventories resulting from the cancellation of the Myanmar contract. Other Operating Expenses Other operating expenses include sales and marketing expenses, general and administrative expenses, patents administration, and development expenses. Sales and marketing expenses decreased 47% to $3.9 million during 1998 as compared to $7.3 million in 1997. The decrease was primarily due to decreased sales commissions and decreased marketing activity for the UltraPhone product. General and administrative expenses for 1998 decreased 24% to $5.4 million in 1998 from $7.2 million in 1997. The decrease was due to cost management and a reduction in workforce in early 1998. Patents administration and licensing costs increased 118% to $11.1 million from $5.1 million in 1997. The increase was primarily due to increased activities related to the generation of licensing revenue and the protection and enforcement of InterDigital's patent portfolio. Development costs decreased 29% to $17.2 million in 1998 from $24.2 million in 1997. The decrease was primarily due to reduced development of InterDigital's UltraPhone system and to the timing of certain B-CDMA related development expenses. Other Income and Expense. Interest income for 1998 increased 24% to $2.5 million from $2.1 million in 1997 due to higher average invested cash balances during 1998. Interest expense of $.4 million was approximately the same in 1998 and 1997. Year 2000 During 1999, we implemented a Year 2000 compliance program, consisting of auditing assessing, remediating, testing, and contingency planning, to ensure that our IT and non-IT systems, as well as the systems of third parties, would function properly when the calendar changed from December 31, 1999 to January 1, 2000. The program covered both systems operated by us as well as systems operated by third parties that we considered to be material to our operations. In total, we have spent approximately $0.3 million in external costs on this program, primarily to upgrade non-compliant hardware and software and the cost of our consultant. We do not expect to incur any significant additional costs related to Year 2000 compliance. We did not experience any significant malfunctions or errors in our operating or business systems when the date changed from 1999 to 2000. Based on operations since January 1, 2000, we do not expect any significant impact to our ongoing business as a result of the "Year 2000 Issue." We are not currently aware of any significant Year 2000 or similar problems that have arisen for third parties upon which we rely. (See Item 1. Business. Risk Factors. Year 2000 Problems May Cause Engineering Difficulties or Delays.") 26 Item 8.

BACKGROUND: InterDigital Communications Corporation (collectively with its subsidiaries referred to as InterDigital, the Company, we, us and our) develops and markets advanced digital wireless communications applications. In conjunction with our technology development, we have developed an extensive body of technical know-how and a broad patent portfolio which we license worldwide and related product embodiments. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Principles of Consolidation The consolidated financial statements include the accounts of InterDigital and its subsidiaries. All significant inter-company accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with generally accepted principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of 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. Cash, Cash Equivalents and Short-Term Investments InterDigital considers all highly liquid investments purchased with remaining maturities of three months or less to be cash equivalents. Investments are held at amortized cost which approximates market value. At December 31, 1999, all of InterDigital's short-term investments were classified as available for sale pursuant to Statement of Financial Accounting Standards ("SFAS") No. 115. "Accounting for Certain Investments in Debt and Equity Securities". At December 31, 1999 and 1998, there were no significant unrealized holding gains or losses. Cash and cash equivalents consist of the following (in thousands): December 31, -------------------- 1999 1998 ---- ---- Money market funds and demand accounts $14,350 $ 3,160 Repurchase agreements 242 516 Commercial paper - 16,383 ------- ------- $14,592 $20,059 ======= ======= 34 The repurchase agreements are fully collateralized by United States Government securities and are stated at cost which approximates fair market value. Short-term investments available for sale as of December 31, 1999 consisted of $35.6 million in government- issued discount notes and $33.0 million in corporate debt securities. Short-term investments available for sale as of December 31, 1998 consisted of $18.2 million in government-issued discount notes and $14.0 million in corporate debt securities. Inventories Inventories are stated at the lower of cost or market, with cost determined on a first-in-first-out basis and market based on net realizable value. Property and Equipment Property and equipment are stated at cost. Depreciation and amortization of property, plant and equipment are provided using the straight-line method. The estimated useful lives for computer equipment, machinery and equipment, and furniture and fixtures are generally three to five years. Leasehold improvements are being amortized over their lease term, generally five to ten years. The buildings are being depreciated over twenty-five years. Depreciation expense was $3.2 million, $3.5 million and $3.2 million in 1999, 1998 and 1997, respectively. Patents The costs to obtain certain patents for InterDigital's TDMA and CDMA technologies have been capitalized and are being amortized on a straight-line basis over 10 years. Amortization expense was $1.5 million, $1.1 million and $1.4 million in 1999, 1998 and 1997, respectively. Development All development expenditures are charged to expense in the period incurred. Revenue Recognition Patent licensing revenues included in licensing and strategic partner revenues, consist primarily of up-front royalty payments and one-time, non-refundable fees which are recognized at the time of the applicable agreement since we have no remaining obligations and do not have any continuing involvement with the licensee. Strategic partner revenues included in licensing and strategic partner revenues are generated by patent, technology and know- how licensing and development agreements. Due to the combined nature of some agreements, revenue may be recognized over the performance period. Royalty revenue is recorded as earned in accordance with the specific terms of each license agreement when reasonable estimates of such amounts can be made. Product revenues are recognized upon shipment of systems. Installation, training and other services are recognized upon completion of services. Concentration of Credit Risk Financial instruments which potentially subject us to concentration of credit risk consist primarily of cash equivalents, short-term investments, and accounts receivable. We place our cash equivalents and short-term investments only in highly rated financial instruments and in United States Government obligations. Our accounts receivable are derived principally from patent license agreements, engineering services and product sales, which provide for deferred and/or installment payments. 35 Impairment of Long-Lived Assets Pursuant to SFAS No. 121. "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of", InterDigital is required to evaluate long-lived assets and certain intangible assets for impairment when factors indicate that the carrying amount of an asset may not be recoverable. When factors indicate that such assets should be evaluated for possible impairment, we review the realizability of our long-lived assets by analyzing the projected undiscounted cash flows in measuring whether the asset is recoverable. In 1999, an $0.8 million charge was taken as a part of a repositioning program. (See Note 3.) No such adjustments were recorded in 1998 or 1997. Net Income (Loss) Per Common Share InterDigital follows SFAS No. 128. "Earnings per Share". The following tables reconcile the numerator and denominator of the basic and diluted net income (loss) per share computation (in thousands, except for per share data): Year Ended December 31, ------------------------------------------------------------------------------------ 1999 1998 ----------------------------------------- --------------------------------------- Income Shares Per-Share Income Per-Share (Numerator) (Denominator) Amount (Numerator) (Denominator) Amount ----------- ------------- ------ ----------- ------------- ------ Income (Loss) per Share-Basic: Income (loss) available to common shareholders $ 26,451 48,357 $ 0.55 $36,713 43,380 $ 0.76 Dilutive effect of options and warrants -- 2,138 $(0.03) -- 391 (0.01) Income (Loss) per Share-Diluted: Income (loss) available to common stockholders + dilutive effects of options and warrants $ 26,451 50,495 $ 0.52 $36,713 48,771 $ 0.75 1997 ----------------------------------------- Income Shares Per-Share (Numerator) (Denominator) Amount ----------- ------------- ------ Income (Loss) per Share-Basic: Income (loss) available to common shareholders $(34,523) 48,166 $(0.72) Dilutive effect of options and warrants -- -- -- Income (Loss) per Share-Diluted: Income (loss) available to common stockholders + dilutive effects of options and warrants $(34,523) 48,166 $(0.72) Options and warrants outstanding during the years ended December 31, 1999 and 1998 to purchase approximately 1.6 and 7.4 million shares of common stock, respectively, were not included in the computation of diluted EPS because the exercise prices of the options were greater than the weighted average market prices of the common stock during the period and, therefore, the effect would be anti-dilutive. All options and warrants 36 outstanding for the year ended December 31, 1997 were excluded from the computation of diluted earnings per share as a result of the net loss for the period. Reclassification Certain prior period amounts have been reclassified to conform to the 1999 presentation. New Accounting Pronouncements In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial Statements." SAB No. 101 expresses the views of the Securities and Exchange Commission in applying generally accepted accounting principles to certain transactions, including licensing agreements. We are in the process of analyzing the impact of SAB No. 101 on our consolidated financial statements. SAB No. 101 will not have any impact on our liquidity or cash flows from operations. 3. REPOSITIONING: In the second quarter of 1999, we recorded a pre-tax repositioning charge of $1.2 million in connection with a change in our strategy from sales and development of wireless local loop products to technology development for advanced wireless applications. This action was taken after assessing our long term business prospects associated with continued investment in the development of wireless local loop systems. The repositioning charge included costs associated with workforce reductions (approximately 27 employees) and asset impairment charges related to wireless local loop development equipment. The components of the repositioning charge included severance and other benefit costs of $0.4 million, all of which were paid in 1999, and asset impairment charges of $0.8 million for fixed assets associated with wireless local loop activities. Management's efforts with respect to this plan are substantially complete. 4. STRATEGIC PARTNER AGREEMENTS: In February 1999, we entered into a long-term cooperation agreement with Nokia for development of new technology for third generation (3G) wireless telecommunications products. As part of the agreement, we will retain ownership rights over the technologies we develop for 3G. Also included in the agreement were certain paid-up TDMA and CDMA licenses, which generally extend through the project period. We recognized revenues of $42.6 million from Nokia in 1999 related to this agreement. These revenues consisted of an initial licensing fee of $31.5 million, development services revenue of $10.8 million, and $0.3 million of recurring royalties. Prior to our 1999 strategic shift to focus on technology development for the 3G market, our development group was focused primarily on technology development of full systems to address needs in the fixed wireless local loop market. As part of that effort, we entered into a series of agreements with Samsung, Siemens and Alcatel to develop B-CDMA technology and products that embodied that technology. These three companies and InterDigital comprised the B-CDMA Alliance. In early 1999, after reassessing the market potential of the residential wireless local loop market, Siemens announced its withdrawal from the B-CDMA Alliance. In April of 1999, Alcatel also withdrew from the B-CDMA 37 Alliance. Minimal activity took place with respect to the Samsung B-CDMA relationship during most of 1999. InterDigital recognized revenue associated with these agreements of $3.1 million, $8.0 million and $4.4 million in 1999, 1998 and 1997, respectively. Of the totals, InterDigital recognized revenues of $3.0 million, $3.4 million, and $2.8 million in 1999, 1998, and 1997 respectively from Samsung, $1.6 million in 1997 from the Siemens and $.1 million in 1999 and $4.6 million in 1998 from Alcatel. 5. MAJOR CUSTOMERS AND GEOGRAPHIC DATA: Revenues by customer geography are as follows (in thousands): Year Ended December 31, ------------------------------------------ 1999 1998 1997 ---- ---- ---- U.S. $ 1,660 $ 1,873 $ 2,853 Non-U.S. 69,007 97,348 46,983 ------- ------- ------- $70,667 $99,221 $49,836 ======= ======= ======= In 1999, 60% of InterDigital's revenue was from our customer in Finland. An additional 26% of revenue was from Japan. In 1998, more than 84% of total revenue was derived from our customers in Japan. In 1997, 66% of revenues were from Indonesia. Additionally, 6% of revenues were from our Philippine customer and another 6% of 1997 revenues were derived from our strategic partner in Korea. Licensing and Strategic Partner Revenue In 1999, ITC entered into 4 new TDMA license agreements with Robert Bosch GMBH, Japan Radio Company, ltd., Shintom Company, LTD. and Iwatsu America, Inc., and granted a combined TDMA and CDMA license to Nokia. In prior years, ITC had granted non-exclusive, non-transferrable, perpetual, worldwide, royalty-bearing licenses to use certain TDMA patents (and in certain instances, technology) to 13additional corporations. Additionally, in prior years, ITC had granted non-exclusive, non-transferrable, perpetual, worldwide, royalty-bearing licenses to use certain CDMA patents (and in certain instances, technology) to Alcatel, Qualcomm and Advanced Digital Technologies and to use TDMA and CDMA patents (and in certain instances technology) to Siemens, Samsung and AT&T. Many of these licenses contain "most favored licensee" provisions, applied on a going forward basis only, and provisions which could, in certain events, cause the licensee's obligation to pay royalties to InterDigital to be suspended for an indefinite period, with or without the accrual of the royalty obligation. Initial revenues from new TDMA licensees in 1999 totaled $42.8 million. 1999 revenues from strategic partners totaled $14.0 million, of which $10.8 was derived from development work for Nokia. In 1999, InterDigital recognized $9.4 million in recurring royalty revenue from its TDMA licenses. During 1998, InterDigital entered into four new TDMA licensing agreements and revised agreements with two existing licensees. These licensing transactions resulted in $83.5 million of revenue in 1998. Additionally, recurring royalty fees of $1.0 million were recognized in 1998. Also in 1998, InterDigital recognized $4.6 million and $3.4 million in revenue related to the Alcatel and Samsung agreements, respectively. In 1997, InterDigital recognized $2.8 million in licensing and strategic partner revenue from Samsung, $1.6 million from Siemens and $1.6 million of recurring royalty revenue from one licensee. 38 6.

Capitalized lease obligations are payable in monthly installments at an average rate of 11.2%, through 2001. The net book value of equipment under capitalized lease obligations is $1.7 million. Maturities of principal of the long-term debt obligations as of December 31, 1999 are as follows (in thousands): 2000 $ 446 2001 326 2002 146 2003 148 Thereafter 1,939 ------ $3,005 ====== 9. COMMITMENTS AND CONTINGENCIES: Leases InterDigital has entered into various operating lease agreements. Total rent expense was $1.4 million in 1999 and 1998 and $1.3 million for 1997, primarily for office, assembly and warehouse space. In 1999, two building leases expired and were not renewed as those facilities had not been currently occupied. Minimum future rental payments for operating leases as of December 31, 1999 are as follows (in thousands): 2000 $1,314 2001 1,349 2002 232 ------ $2,895 ====== 40 Employment Agreements InterDigital has entered into agreements with certain officers that provide for the payment of severance pay benefits, among other things, in certain events of termination of employment. These agreements generally provide for the payment of severance up to a maximum of one year's salary (approximately $1.9 million at December 31, 1999) and up to a maximum of one year's continuation of medical and dental benefits. In these agreements, in the event of a termination or resignation within one year following a change of control, which is defined as the acquisition, including by merger or consolidation, or by the issuance by InterDigital of its securities, by one or more persons in one transaction or a series of related transactions, of more than fifty percent (50%) of the voting power represented by the outstanding stock of InterDigital, the employee would receive generally two years of salary (approximately $3.7 million at December 31, 1999) and the immediate vesting of all stock options. 10. LITIGATION: In September 1993, ITC filed a patent infringement action against Ericsson GE Mobile Communications, Inc. ("Ericsson GE"), its Swedish parent, Telefonaktieboleget LM Ericsson ("LM Ericsson") and Ericsson Radio Systems, Inc. ("Ericsson Radio"), in the United States District Court for the Eastern District of Virginia (Civil Action No. 93-1158-A (E.D.Va.)) (the "Ericsson action") which was subsequently transferred to the United States District Court for the Northern District of Texas. The Ericsson action seeks a jury's determination that in making, selling, or using, and/or in participating in the making, selling or using of digital wireless telephone systems and/or related mobile stations, Ericsson has infringed, contributed to the infringement of and/or induced the infringement of eight patents from ITC's patent portfolio. The Ericsson action also seeks an injunction against Ericsson from infringement and seeks unspecified damages based upon the court's determination of what constitutes a reasonable royalty for infringement, royalties, costs and attorneys' fees. Ericsson GE filed an answer to the Virginia action in which it denied the allegations of the complaint and asserted a Counterclaim seeking a Declaratory Judgment that the asserted patents are either invalid or not infringed. On the same day that ITC filed the Ericsson action in Virginia, two of the Ericsson Defendants, Ericsson Radio and Ericsson GE, filed a lawsuit against InterDigital and ITC in the United States District Court for the Northern District of Texas (the "Texas action"). The Texas action, which involves the same patents that are the subject of the Ericsson action, seeks the court's declaration that Ericsson's products do not infringe ITC's patents, that ITC's patents are invalid and that ITC's patents are unenforceable. The Texas action also seeks judgment against InterDigital and ITC for tortious interference with contractual and business relations, defamation and commercial disparagement, and Lanham Act violation. The Ericsson action and the Texas action have been consolidated. ITC agreed to the dismissal without prejudice of LM Ericsson. In December 1997, Ericsson Inc., the successor to Ericsson GE and Ericsson Radio, filed an action against ITC in the United States District Court for the Northern District of Texas (the "1997 Texas action") seeking the court's declaration that Ericsson Inc.'s products do not infringe two patents issued to InterDigital earlier in 1997 as continuations of certain patents at issue in the Texas action. Later that month, Ericsson Inc. filed an amended Complaint seeking to include these two new patents in the Texas action in an effort to consolidate the two cases. In January 1998, both Ericsson Inc. and InterDigital and ITC filed motions requesting that Ericsson Inc's amended Complaint be allowed and that the 1997 Texas action be dismissed, to which the Court agreed. In 1998, Ericsson Inc. filed a Motion for Partial Summary Judgement, which was denied by the Court in early 1999. Also during 1998, the United States District Court for the Northern District of Texas granted InterDigital's Motion to amend its Counterclaim by adding four additional patents. During the third quarter of 1999, Ericsson Inc. filed for leave to file an additional Amended Complaint to add causes of action for breach of contract and fraud and negligent misrepresentation. The Court granted Ericsson's request. Fact discovery has been substantially concluded. The "Markman" hearing is scheduled to take place in April, 2000 where a Special Master will make recommendations 41 to the court as to the meaning of certain terms contained in the patents. InterDigital records expenses for fees related to litigation as they are incurred. Such fees are included as patents administration and licensing expense. During the year ended December 31, 1999, the Company recovered certain expenses related to this litigation from its insurance carrier. Such recoveries are included as a reduction to patents administration and licensing expense when they are submitted to the insurance company. In February 2000, the Company and its insurers defined the method, timing and limitations of reimbursements for covered litigation expenses. Also, on October 27, 1999, Cavalier Technologies and Consultants Ltd. ("Cavalier") filed suit against us in the United States District Court of the Eastern District of Pennsylvania for breach of contract to team to supply and breach of contract to supply UltraPhone systems in Kenya and for fraudulent representations as to our future plans for the UltraPhone business. Concurrently with the filing of its Complaint, Cavalier filed a request for a Temporary Restraining Order and a Motion for a Preliminary Injunction to prevent us from shipping any of our remaining inventory of UltraPhone equipment to other customers. The Court denied the TRO application, and scheduled a preliminary injunction hearing. In December, 1999, the Court issued a bench ruling denying Cavalier's motion for a preliminary injunction on the grounds that Cavalier had failed to demonstrate irreparable harm. Cavalier continues to seek damages and injunctive relief. We have asserted a damages counterclaim for past due balances. 11. PREFERRED STOCK: The holders of the $2.50 Convertible Preferred Stock are entitled to receive, when and as declared by our Board of Directors, cumulative annual dividends of $2.50 per share payable in cash or Common Stock (as defined) at the Company's election (subject to a cash election right of the holder), if legally available. Such dividends are payable semiannually on June 1 and December 1. In the event we fail to pay two consecutive semiannual dividends within the required time period, certain penalties may be imposed. The $2.50 Convertible Preferred Stock is convertible into Common Stock at any time prior to redemption at a conversion price of $12 per share (subject to the adjustment under certain conditions). In 1999, 1998 and 1997, InterDigital declared and paid dividends on the $2.50 Convertible Stock of $255,000, $255,000 and $256,000, respectively. These dividends, were paid with cash of $168,000, $202,000 and $162,000, and 17,530, 8,860 and 19,281 shares of Common Stock, respectively. Upon any liquidations, dissolution or winding up of InterDigital, the holders of the $2.50 Convertible Preferred Stock will be entitled to receive, from InterDigital's assets available for distribution to shareholders, $25 per share plus all dividends accrued, before any distribution is made to the Common shareholders, after such payments, the holders of the $2.50 Convertible Preferred Stock would not be entitled to any other payments. The redemption price for each share of $2.50 Convertible Preferred Stock is $25 per share. The holders of the $2.50 Convertible Preferred Stock do not have any voting rights except on those amendments to be Articles of Incorporation which would adversely affect their rights, create any class or series of stock ranking senior to or on a parity with the $2.50 Preferred Stock, as to either dividend or liquidation rights, or increase the authorized number of shares of any senior stock. In addition, if two or more consecutive semiannual dividends on the $2.50 Preferred are not paid by InterDigital, the holders of the Preferred, separately voting as a class, will be entitled to elect one additional director of InterDigital. 42 12. COMMON STOCK COMPENSATION PLANS AND WARRANTS Stock Compensation Plans InterDigital has stock-based compensation plans under which, depending on the plan, directors, employees, consultants and advisors can receive stock options, stock appreciation rights, restricted stock awards and other stock unit awards. Common Stock Option Plans InterDigital has granted options under two incentive stock option plans, four non-qualified stock option plans and one plan which provides for grants of both incentive and non-qualified stock options to non-employee directors, officers and employees of InterDigital and certain others, depending on the plan. One incentive stock option plan, three non-qualified stock option plans and the plan that allows for both incentive and non-qualified stock options are authorized to grant options for up to 600,000, 2,035,600, 1,500,000, 2,000,000 and 4,000,000 shares, respectively of InterDigital's Common Stock. No further grants are allowed under the remaining stock option plans. The Board of Directors or a Committee of the Board determines the number of options to be granted. The option prices are determined based on market prices in accordance with the terms of the plans. Under the terms of the incentive stock option plan, the option price cannot be less than 100% of fair market value of the Common Stock at the date of grant and incentive stock options granted become exercisable at 20% per year beginning one year after date of grant and generally remain exercisable for 10 years. Under the non-qualified option plans, options are generally exercisable for a period of 10 years from the date of grant and may vest on the grant date, another specified date or over a period of time. All options granted under the plan which provides for both incentive and non-qualified stock options to non-employee directors and grants awarded to inventors most commonly vest in six bi-annual installments. All incentive options granted under such plan have exercise prices of not less than 100% of the fair market value of the Common Stock on the grant date in accordance with Internal Revenue Code requirements. SFAS No. 123 Disclosure InterDigital has adopted the disclosure-only provisions of Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" (SFAS No. 123). Accordingly, no compensation cost has been recognized in the Statements of Operations for InterDigital's stock option plans. Had compensation cost been calculated based on the fair value at the grant due for awards in 1999, 1998 and 1997 consistent with the provision of SFAS No. 123, InterDigital's net income (loss) and net income (loss) per share would have been changed to the following pro forma amounts: 1999 1998 1997 ---- ---- ---- Net income (loss) applicable to Common Shareholders - as reported $26,451 $36,713 $(34,523) Net income (loss) applicable to Common Shareholders - pro forma $23,540 $32,837 $(37,894) Net income (loss) per share - as reported - basic $ 0.55 $ 0.76 $ (0.72) Net income (loss) per share - as reported - diluted $ 0.52 $ 0.75 $ (0.72) Net income (loss) per share - pro forma - basic $ 0.49 $ 0.68 $ (0.79) Net income (loss) per share - pro forma - diluted $ 0.47 $ 0.67 $ (0.79) The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions used for grants in 1999, 1998 and 1997; no dividend yield; expected volatility of 125% for 1999, 83% for 1998, 70% for 1997, risk-free interest rates of approximately 5.66%, 5.27% and 6.24% for 1999, 1998 and 1997, respectively, and an expected option life of 4.40 years for 1999, 3.05 43 years for 1998 and 3.72 years for 1997. The weighted average fair value at the date of grant for options granted during 1999, 1998 and 1997 is estimated as $6.61, $3.05 and $2.89 per share, respectively. The following table summarizes information regarding the stock options outstanding at December 31, 1999 (in thousands, except per share amounts): Information with respect to stock options under the above plans is summarized as follows (in thousands, except per share amounts): Weighted Available Outstanding Options Average for ------------------------ Exercise Grant Number Price Range Price ----- ------ ----------- ----- BALANCE AT DECEMBER 31, 1996 5,604 4,389 $.01-$14.875 $7.14 Granted (2,539) 2,539 $4.375-$5.688 $5.45 Canceled 879 (879) $5.250-$14.500 $9.15 Exercised - (3) $0.600-$5.625 $4.79 BALANCE AT DECEMBER 31, 1997 3,944 $.01-$11.625 $6.14 Granted (608) 608 $3.250-$5.6875 $5.04 Canceled 715 (715) $5.375-$10.750 $3.13 Exercised - (153) $0.600-$5.625 $3.13 BALANCE AT DECEMBER 31, 1998 4,051 5,786 $.01-$11.625 $6.05 Granted (689) 689 $4.3750-$11.0 $7.49 Canceled 397 (397) $5.25-$10.5 $7.50 Exercised - (1,660) $0.1-$11.625 $5.77 ----- BALANCE AT DECEMBER 31, 1999 3,759 4,418 $.01-$11.625 $6.26 Common Stock Warrants As of December 31, 1999, we had various warrants outstanding to purchase 3.0 million shares of Common Stock at exercise prices ranging from $2.50 to $10.00 per share, with a weighted average exercise price of $5.37 per share. As of December 31, 1999, all of these warrants were currently exercisable. These warrants expire in various years through 2006. The exercise price and number of shares of Common Stock to be obtained upon exercise of certain of these warrants are subject to adjustment under certain conditions. Restricted Stock In 1999, we adopted the 1999 Restricted Stock Plan, under which we can issue up to 1,500,000 shares of restricted common stock and restricted stock units to directors, employees, consultants and advisors. As of December 31, 1999, we had 322,000 shares of restricted Common Stock issued and outstanding. The restrictions lapse over periods ranging from 1.5 to 5.5 years from the date of the grant. We recorded unearned compensation of $1.9 million for the value of the restricted stock, which is being amortized over the respective vesting periods. We also accrued a $1.3 million liability in 1999 for the pro-rata share of the estimated liability associated with certain tax reimbursement features of this Plan. We are in the process of replacing the tax reimbursement features related to certain of the grants with restricted stock unit grants. 13. SHAREHOLDER RIGHTS PLAN In December 1996, InterDigital's Board of Directors declared a distribution under its Shareholder Rights Plan of one right for each outstanding common share of InterDigital to shareholders of record as the close of business on January 3, 1997. In addition, any new common shares issued after January 4, 1997 will receive one right for each common share. The Plan was amended in a number of respects in March 2000. As amended, each right entitles shareholders to buy one one-thousandth of a share of Series B Junior Participating Preferred Stock at a purchase price of $250 per share, subject to adjustment. Ordinarily, the rights will not be exercisable until 10 days after a non-exempt person or group owns or acquires more than 10% of InterDigital's outstanding Common Stock or a non-exempt person or group begins an offer for 10% or more of InterDigital's outstanding Common Stock or after a non-exempt person or group publicly announces an intent to acquire control over InterDigital and proposes in a proxy or consent solicitation to elect such a number of directors which, if elected, would represent a majority of the directors when compared with the Independent Directors continuing to serve on the Board. In general, in the event that InterDigital is acquired in a merger or other business combination interaction, each holder of a right will have the right to receive, upon exercise, Units of Preferred Stock (or, in certain circumstances, Company Common Stock, cash, property, or other securities of InterDigital) having a current market value equal to two times the exercise price of the Right. 14. INCOME TAXES: The 1999 income tax provision includes a federal alternative minimum tax provision of $0.6 million and a foreign withholding tax provision of $2.6 million. The 1998 income tax provisions includes a federal alternative minimum tax provision of $0.9 million, a foreign withholding tax provision of $8.3 million. The 1997 income tax provision includes a current state tax provision of $34,000. At December 31, 1999, InterDigital had net operating loss carryforwards of approximately $95.6 million. Since realization of the tax benefits associated with these carryforwards is not assured, a valuation allowance of 100% of the potential tax benefit is recorded as of December 31, 1999. 44 The net operating loss carryforwards are scheduled to expire as follows: 2002 $ 6.8 million 2003 18.2 million 2004 20.0 million 2005 11.9 million thereafter 38.7 million ------------- $95.6 million ============= Pursuant to the Tax Reform Act of 1986, annual use of InterDigital's net operating loss and credit carryforwards may be limited if a cumulative change in ownership of more than 50% occurs within a three-year period. The annual limitation is generally equal to the product of (x) the aggregate fair market value of InterDigital's stock immediately before the ownership change times (y) the "long-term tax exempt rate" (within the meaning of Section 382(f) of the Code) in effect at that time. InterDigital believes that no ownership change for purposes of Section 382 occurred up to and including December 31, 1999. InterDigital's calculations reflect the adoption of new Treasury Regulations which became effective on November 4, 1992 and which have beneficial effects regarding the treatment of options and other aspects of the ownership change calculation. 45 Item 7A.
