General The Company develops, markets, distributes and supports a diversified mix of products and services for the telecommunications industry. Over the past 12 years, the Company has developed expertise in real-time wireless call processing and has created technologically advanced solutions for this industry, focusing primarily in the area of wireless communications fraud management. The Company's Blackbird Platform Products are sold in this arena. During 1999 and 2000, the Company implemented a short and long-range strategic plan to diversify its product mix, both within and outside of the telecommunications industry. This diversification strategy is at the foundation of the Company's growth plan for the future. In the fourth quarter of 1999, as part of its diversification strategy, the Company launched Isis Tele-Communications, Inc. ("Isis"), a majority-owned subsidiary, which designs, markets, and distributes both regionally and nationally branded prepaid long-distance phone cards. Also in the fourth quarter of 1999, the Company made a strategic investment in KSI, Inc. ("KSI"), a provider of development-stage wireless geo-location technology. The Company made further investments in KSI during 2000. KSI was acquired by TruePosition, Inc. ("TruePosition") in August 2000; as a result, the Company's investment in KSI became and remains one in TruePosition. This technology is expected to provide a platform for hosting a variety of location-sensitive consumer applications for the wireless communications market. The Company expects to leverage its entrance into the geo-location marketplace by developing, marketing, distributing, and supporting a suite of commercial geo-location applications as this technology evolves and is commercially deployed by wireless carriers. In late 2000 the Company created a division called Neumobility'TM' to develop and market its range of geo-location wireless software applications. Presently, the Company's major customers are wireless telephone carriers for its Blackbird Platform Products. These carriers operate in a dynamic, rapidly changing environment and are subject to intense competition, cost sensitivity and other market forces. Customers for the Company's Isis phone card segment are primarily distributors, retailers and convenience stores, which also operate in highly competitive marketplaces. These and other related factors have influence on the Company's direction for the future. The Company believes that these factors will provide opportunities for new products and services in a wide variety of markets. 3

Products The Blackbird Platform Products The Company's Blackbird'r' Platform product line includes a suite of radio frequency ("RF") based platform solutions focusing on wireless fraud prevention. Presently, it involves various forms of "pre-call" verification to ensure that the use of an analog wireless telephone is legitimate before the device is allowed to connect to a carrier's analog wireless communications network. In this area, the Company is a leading provider of RF-based solutions for the prevention of "cloning fraud." This term is used to describe the illegal activity of using a scanning device to steal the electronic serial number and mobile identification number of a legitimate wireless telephone while in use, then reprogramming the stolen numbers into other phones. These reprogrammed phones, or "clone phones," are then used to make illegal calls on a wireless communications network, without payment for the wireless services rendered. The Company's suite of RF-based platform solutions include the Blackbird'r' Platform, PreTect'TM' cloning-fraud prevention application, No Clone Zone'sm' roaming-fraud prevention service, and related application products and services (collectively, the "Blackbird Platform Products"). The Company's Blackbird Platform Products are currently deployed in approximately 1,600 cell sites in most major metropolitan areas throughout the United States. The Company's customers have reported up to a 98% reduction in cloning fraud activity in areas served by the Blackbird Platform Products since its initial installation, and continue to rely on its cloning prevention capabilities for their existing analog wireless communications networks. The Blackbird Platform. The Blackbird Platform provides real-time collection, distribution, storage and reporting of pre-call data retrieved from an analog wireless communications network. It is designed to deliver centralized control and efficiencies of operation based on industry standards, open systems and real-time distributed messaging. The Blackbird Platform Products incorporate software and hardware designs that use the UNIX operating system with TCP/IP message transport networking, supporting both client-server and peer-to-peer communication architectures. This operating system environment is widely used and accepted in the telecommunications industry. The PreTect Application. The PreTect application employs patented RF "fingerprinting" technology to proactively prevent cloning fraud in real-time. It accomplishes this by building RF fingerprints of legitimate subscribers' wireless phones using the pre-call data collected by the Blackbird Platform. An RF fingerprint is the wireless phone's unique electromagnetic signal waveform characteristics contained in each phone, with no two RF fingerprints being exactly the same. The PreTect application compares RF fingerprints of incoming call requests to its database of RF fingerprints for validated legitimate subscriber phones and also examines usage characteristics to assist in verifying authenticity. It then directs automatic call "tear-down" or interdiction of a fraudulent call before connection is completed. The PreTect application provides proactive pre-call fraud prevention rather than post-call fraud detection. The No Clone Zone Service. The Company has developed a roaming-fraud prevention service, known as the No Clone Zone service, which provides seamless, RF-based roaming fraud prevention. The No Clone Zone service proactively and transparently prevents roaming cloning fraud in markets that utilize the Blackbird Platform and PreTect fraud prevention application. The service leverages the underlying power of existing Blackbird Platform deployments, and the Blackbird Platform's real-time distributed messaging system, to quickly and seamlessly link participating carrier systems nationwide, into a private, high-speed cloning fraud prevention network. Blackbird Platform Monitoring Option. The Company has developed system-monitoring technology for the Blackbird Platform Products that provides real-time capabilities for monitoring overall system health of any network-based distributed applications. The Company's Blackbird Platform Monitoring product provides sophisticated real-time alarming of system performance exceptions that can be directed to a centralized call center. The product is designed to support industry standards with the flexibility of open architecture and platform portability. Additionally, the Company provides a Blackbird Platform Monitoring service, available to all Blackbird Platform customers, which is hosted from the Company's Seattle headquarters call center. This provides 4

a flexible alternative for customers who have limited expertise to perform this critical component of fraud system management to keep the Blackbird Platform Products at optimal performance 24 hours per day, 7 days per week. Blackbird Backup & Restore Option. The Company has developed the Blackbird Backup & Restore product that optimizes and validates the storage of critical data in the event of system failure so complete reconstruction can be performed easily. This product provides a completely automated operation with customizable scheduling flexibility, requiring no manual intervention by customer personnel. Blackbird Platform Professional Services. The Company provides system performance analysis, system project planning, configuration, implementation and other professional services in connection with its Blackbird Platform Products. Customers are charged hourly rates for such services or may contract with the Company for fixed fees. Prepaid Wireline Long-Distance Phone Cards To stimulate revenue growth for the Company, and in alignment with its product diversification strategy, the Company expanded into the prepaid long-distance service arena in the fourth quarter of 1999. Prepaid long-distance service represents one of the fastest growing sectors of the telecommunications industry, with growth in this market accelerating as a result of the Telecommunications Act of 1996. According to the International Telecard Association, prepaid long-distance calling card revenues in the United States have grown from an estimated $12.0 million in 1992 to an estimated $2.1 billion in 1997, and they are projected to be at least $4.0 billion in 2001. Growth in this market is has been driven by a large population of consumers such as first generation immigrants, students, temporary residents, and lower-income individuals, who in many instances do not have local phone service due to credit or identification problems. The Company expects that growth in this market will both continue in these customer groups and expand to other customer groups as prepaid phone cards become more widely adopted. Through its majority-owned subsidiary, Isis, the Company markets and distributes branded prepaid long-distance phone cards in denominations generally ranging from $5 to $20 per card. Isis specializes in targeted marketing programs with aggressive domestic and international long-distance rates. Isis distributes cards through regional and national multi-level distribution channels, using direct sales, third-party distributors, and telemarketing. End users of these cards can use them by dialing the local or toll-free access number identified on the card, keying in a personal identification number (a "PIN") that is assigned to the card, and then dialing the telephone number that the end user seeks to reach. The third-party long-distance service provider then completes the call, debits the balance on the card following the call, and provides customer assistance as necessary. The Company anticipates that its ability to provide aggressive per-minute rates, broad multi-level distribution coverage, and quality customer service will be the key ingredients for continued revenue growth and expansion of this product line. Isis has offices in Los Angeles, Boston, and Chicago. TruePosition Investment and Neumobility Products The Federal Communications Commission ("FCC") has required all wireless carriers to deploy wireless geo-location technology by October 2001 to provide comparable 911 services to wireless telecommunications subscribers. Wireless geo-location technology provides and identifies the specific geographic location (in latitude and longitude measurements) of a wireless telephone, and can eventually be applied to other wireless communications devices. Industry analysts have estimated the market for commercial geo-location applications to be well over $8.0 billion. During the fourth quarter of 1999, and as part of the Company's long-term diversification strategy, the Company made a strategic investment in KSI, Inc. ("KSI"), a provider of development-stage wireless geo-location technology. In August 2000, TruePosition, Inc., a subsidiary of Liberty Media Corporation, acquired KSI. The Company's total investment in TruePosition, Inc. common stock at December 31, 2000 was $1,758,000. 5

In late 1999 the Company began development of a location-based wireless software product platform and mobile commerce applications. The Company expects to leverage its entrance into the geo-location marketplace by developing, marketing, distributing, and supporting a suite of commercial geo-location applications as the technology evolves and is deployed by all wireless carriers to comply with the FCC's requirements. In January 2001 the Company formed a division called Neumobility'TM' for this product line. The Neumobility family of products includes a scalable platform and an application suite providing location-based information utilizing both network and satellite positioning technologies. The platform is called NeuTrac'TM', and is a system utilizing positioning data to create, maintain and deliver relevant content and services in a location-based format. The NeuTrac platform is configurable and creates a combination of subscription-based, pay-per-use and free value-added services. The application suite will include: NeuCommerce'TM', which allows for personalized, permission-based one-to-one marketing; NeuMerchant'TM', which allows for the tracking of merchant offers and creates metrics to analyze the impact of marketing efforts; NeuMap'TM', which creates directions based upon positioning data; NeuList'TM', which adds a location-sensitive component to wireless e-mail functions; and NeuJournal'TM', a journaling feature which allows for the documentation of location and content. The Company anticipates completing the initial product suite in 2001. The Telecommunications Industry The Telecommunications Act of 1996 was implemented to stimulate competition in all arenas of the telecommunications industry. The results have provided consumers with a broader spectrum of cost-effective service choices for their telecommunication needs. Correspondingly, the wireless industry has seen a dramatic expansion. The Cellular Telecommunications Industry Association has estimated that the number of wireless telephone subscribers in the United States increased from approximately 340,000 subscribers in 1985 to approximately 75 million subscribers in 1999. Industry analysts believe that the number of wireless telephone subscribers may grow to in excess of 120 million in the United States by the end of 2001. International market analysts have forecast that total worldwide wireless telephone service revenue will grow to $360 billion by the end of 2002. Key Issues Resulting from Increased Competition in the Telecommunications Industry Lower price per minute has driven minutes of usage up. The increased presence of multiple telecommunications carriers in any given market has spawned a number of new single-rate pricing plans, effectively driving the price per minute of wireless telephone usage substantially lower. As a result, wireless telephone carriers must supplement revenues by implementing new subscriber service offerings to not only grow, but also preserve their existing subscriber base. New add-on consumer services (such as text messaging, stock quote delivery and transportation alerts) are expected to continue to drive the minutes of use up, which should position the wireless communication device as the only communication device an individual will need to own, covering both communication and personal information management needs of the future. Nearly one-third of all new subscribers leave each year. Customer "churn," which is when a subscriber switches from one wireless carrier to another in a short amount of time, has become a significant problem facing the wireless telephone carriers today. Churn not only results is a loss of subscriber revenue, but also makes it difficult for carriers to recover the significant costs associated with acquiring new subscribers. Presently, churn is running in the range of 25% - 35% per year for most carriers, according to industry sources. This level is expected to remain high as competition to attract new subscribers continues. Aggressive rate plans and bundled service packages, including free roaming and free or low-cost long-distance rates have served to differentiate one wireless carrier from another. However, the Company believes that the availability of consumer applications and services by carriers that integrate personalized information, the internet, and email messaging may prove to be the most effective tool for managing subscriber churn. Prepaid market has expanded to capture new consumers. Prepaid service represents one of the fastest growing sectors of the telecommunications industry and is providing a new point of differentiation in local markets as 6

telecommunication carriers expand their service offerings. Once driven primarily by a large population of first generation immigrants, students and lower-income individuals, a variety of prepaid services is rapidly expanding toward the mainstream in the United States. This expansion is primarily due to the widespread availability of competitive long-distance rates, the convenience of a set-limit debit card for long-distance calling, and an easy solution for travel and emergency situations. Competition has raised consumer expectations on service offerings. The intense competition in the telecommunications market is placing new pressures on wireless telephone carriers to differentiate their service offerings. As the wireless communications device becomes capable of receiving a wider variety of communications, i.e., voice messaging, paging, or emails, the Company believes that wireless subscribers will require and expect a robust suite of consumer services that not only replicate what landline service providers offer (such as emergency 911 assistance), but also provide new ways to access personalized information through their wireless phone. Examples include roadside assistance, asset tracking, personalized information or "concierge" service ("E411") and traffic advisories, and others. The Company believes the results of competition in the telecommunications market, including lower price per minute, higher minutes of usage, and demand for new sources of carrier revenue, will continue to provide diversified market opportunities for the Company's existing products and services, as well as new offerings in the future. The Company's Strategy The Company believes the key issues affecting the telecommunications industry described above support and validate the Company's strategic direction toward diversification. 1. Diversify the Company's product mix within the growing telecommunications market. The Company believes that the present dynamics of the telecommunications industry will result in a proliferation of new service applications focused on mobile information management. These services may include such things, for example, as prepaid calling services, location-sensitive advertising, stock quote notification and weather advisories. The Company believes that many of the new applications will be enhanced by the addition of geo-location technology. As the Company further expands on its diversification plan, it believes it will be well positioned for offering a variety of new consumer-convenience products and services. The Company expects that these target offerings may help the carriers reduce churn and increase revenues, while enhancing the Company's market position beyond its current products and services, enlarging its customer base across multiple sectors, and providing for both near-term and long-term revenue growth. 2. Leverage existing intellectual property in new ways. The Company believes it can leverage its core expertise and patented technology in the real-time information management area to develop new products and services. The Company has developed unique expertise in the area of distributed real-time computing over high-speed, interlinked networks on a nationwide scale. This capability allows the Company to acquire data and perform information processing in a highly distributed environment, such as encountered in wireless infrastructures. The Company believes this expertise will be particularly useful in the development of new commercial geo-location applications. The Company has also developed the ability to combine streams of telephone billing information, such as toll charges, discounts, promotions and surcharges to mimic a carrier's billing system on a real-time basis. This happens within minutes after the end of the call, rather than in the typical batch process for monthly customer billing cycles. The Company's focus on diversification supports the continued use of its intellectual property, providing cost-savings and accelerating product development efforts for new telecommunications products and services. 7

3. Deliver exceptional customer service. The Company believes the ability to provide knowledgeable, high quality customer service is a critical success factor for servicing the needs of wireless telephone carriers as they implement new commercial applications. The Company currently provides real-time system monitoring 24 hours per day, 7 days per week for its Blackbird Platform Products through its call center located at the Seattle headquarters. Additionally, the Company provides regional technical support personnel in major markets for on-site maintenance service of its systems, ensuring optimal uptime performance. The Seattle call center employs sophisticated commercial call tracking and system alarming software, integrated with the Company's own proprietary Blackbird technology, and is staffed with technicians who are required to meet continuous training objectives. Through its knowledge of unique customer technical requirements, the Company believes it can expand these same technical support service offerings to support other new commercial applications it develops for the telecommunications marketplace, as well as products and services offered in new markets. Product Development For the years ended December 31, 2000, 1999 and 1998, the Company incurred gross research and development expenditures of $1.5 million, $1.6 million and $5.1 million, respectively. The 1998 period included $0.6 million of capitalized software development costs. The Company ceased capitalization of software development costs during 1998. The Company's current research and development efforts are focused on enhancing and improving existing products and services, and developing new products and services, including new software applications and technology interfaces. These enhancements and/or new products and services may, when and if developed, enable the Company to expand on its existing products and services to provide a broad variety of functions not presently offered. Costs included in the Company's gross research and development expenditures include costs for research, design, development, tests, and preparation of training and user documentation. The Company anticipates that it will continue to commit significant resources to product development in the future to address market opportunities for new and enhanced products and services. See also "Business Risks -- Dependence on New Product Development and Product Enhancements" below. Sales, Marketing and Distribution The Company primarily markets Blackbird Platform Products directly to wireless telephone carriers operating analog networks in the most heavily populated United States markets. The Company sells and licenses Blackbird Platform Products pursuant to agreements that typically provide for hardware purchases, software licenses, customer support and the provision of related services. The Company designs and markets its own prepaid phone cards and also resells prepaid phone cards produced by others. The Company markets prepaid phone card products primarily through regional and national multi-level distribution channels, using direct sales, third-party distributors, and telemarketing. These marketing efforts are pursuant to distribution agreements and other forms of sales and marketing arrangements. The Company also participates at targeted trade shows, conferences and industry events to augment its marketing efforts. The Company further consults with its current and prospective customers to gather product feedback to assist the Company in determining product direction. Achieving greater market acceptance and penetration of the Company's products and services will require, in addition to enhancing and improving its products and services, increased marketing efforts and the expenditure of funds to increase customer awareness of the Company and to inform potential customers of the benefits of the Company's products and service offerings. See also "Business Risks -- Fluctuations in Quarterly Performance," "Business Risks -- "Need for Additional Financing" and "Business Risks - Dependence on Distributors" below. Revenues from Blackbird Platform Products represented 31% of the Company's total revenue in 2000, and 96% of the Company's total revenues in 1999 and 1998. The Company anticipates that revenues from Blackbird Platform 8

Products will continue to represent a meaningful portion of the Company's total revenue in 2001, but that the Company's dependence on Blackbird Platform Products will decrease during 2001 as revenues from its prepaid phone card products continue to represent a larger portion of total revenue. See also "Business Risks -- Dependence on Limited Product Base; Uncertainty of Widespread Market Demand" below. Customer Support and Services The Company provides hardware maintenance, software maintenance, software subscription services (for software upgrades and new releases), the No Clone Zone service and Blackbird Platform Monitoring service to its customers of Blackbird Platform Products. Customer service personnel diagnose and resolve problems, dispatch third-party vendors, provide provisioning and integration services, forward enhancement requests to the Company's product management staff, and coordinate with customers with respect to software upgrades and new releases. From its centralized call center in Seattle, Washington, the Company monitors and maintains a national high-speed network for optimizing uptime and connectivity to the local area networks of its customers. The Company also provides on-site maintenance services for selected customers. Software troubleshooting, maintenance and upgrades are performed either through the Company's private data network or through modem over a standard telephone line. An on-line customer management system tracks problems and resolutions. Customer service is available 24 hours per day, seven days per week. Engineering research and development personnel assist in software support activities to the extent required. Major Customers The customers of the Company's Blackbird Platform Products are wireless telephone carriers. The Company has agreements with Verizon Wireless, Ameritech Mobile Communications, Inc. ("Ameritech") and SNET Mobility ("SNET") to deploy and support Blackbird Platform Products. As a result, the Blackbird Platform Products are currently operational in many of the largest markets throughout the United States, including New York, Boston, Hartford/New Haven, Philadelphia, Baltimore, Washington D.C., Chicago, Detroit, Milwaukee, St. Louis, Atlanta, Los Angeles, San Francisco, San Diego and Sacramento. Revenues from the Company's agreements with Verizon accounted for 24% of the Company's total revenues in 2000. See "Business Risks -- Limited Customer Base; Reliance on Significant Customers" below. Competition The market for the Company's products and services is highly competitive and subject to rapid technological change, regulatory developments and emerging industry standards. The Company believes that the principal competitive factors in the markets in which the Company competes include factors such as product effectiveness, quality and ease of use, technical support, customer service, price, the availability of real-time information and the financial stability of the vendor. A number of companies currently offer one or more products or services similar to the products and services offered by the Company. In addition, many carriers and vendors of telecommunications products are or may be capable of developing and offering products and services that are competitive with the Company's current or future offerings. Trends in the telecommunications industry, including greater consolidation and technological developments that make it easier or more cost-effective for carriers to develop or provide certain services themselves, could affect demand for any new products or services offered by the Company, and could make it more difficult for the Company to offer cost-effective alternatives to a carrier's own in-house capabilities. The Company is aware of various competitors which currently or are expected to compete directly with the Company's Blackbird Platform Products in the cloning fraud prevention arena. One competitor, Lightbridge Inc., competes directly with the Company's RF-based cloning fraud prevention products and services. The Company also competes with a number of alternative technologies in this arena, including roamer verification reinstatement systems, profiler systems, personal identification numbers and A-Key authentication systems. Companies marketing such technologies include, among others, Nortel Networks, TSI Telecommunications Services, Inc., Lightbridge, Inc., and Systems/Link Corporation. The A-Key authentication technology is provided by telephone 9

switch and wireless handset manufacturers (e.g., Lucent Technologies, Inc., Ericsson Radio Systems AB, Motorola, Inc., Nokia and Nortel Networks). An additional competitive factor in the cloning fraud prevention arena includes the compatibility with cloning fraud prevention products used by the carrier in other geographic markets and by the carrier's roaming partners. The Company believes that carriers purchasing RF fingerprinting fraud prevention products tend to purchase these products from the same vendor that supplies these products to their roaming partners. Thus, the Company believes it will be more difficult to market its Blackbird Platform Products to a carrier if the carrier's roaming partners are using RF fingerprinting fraud prevention products supplied by a competitor. The Company believes that A-Key authentication, in particular, poses significant future competition for the Blackbird Platform Products in the cloning fraud prevention arena. A-Key authentication is a form of cryptographic authentication that uses a complex algorithm derived from a mathematical cryptographic process containing a secret key (or number) shared only by the phone and the carrier's network. A-Key authentication is expected to be the form of cryptographic authentication most widely adopted by wireless telephone carriers in the United States. Today, almost all new digital and analog phones for the U.S. market are being manufactured with A-Key authentication capability. A-Key authentication is now in extensive use by wireless telephone carriers operating digital networks and, to a lesser extent, is now in use by certain wireless telephone carriers operating analog networks. However, the Company believes that the use of A-Key authentication is currently limited in analog networks due to the large number of existing analog phones that were not manufactured with A-Key authentication capability. The Company also is aware of many competitors which currently or are expected to compete directly with the Company's prepaid phone card products. In part, these competitors include both the long-distance telecommunications service providers as well as their service resellers, including service providers and resellers for whom the Company resells prepaid long-distance telephone services through its prepaid phone card products. Many of these competitors, including AT&T Corp., MCI WORLDCOM, Inc. and Sprint Corporation, are substantially larger and have longer operating histories, greater name recognition, larger customer bases, and substantially greater financial, marketing, technical and other resources than the Company. Additional competitive factors in the prepaid phone card arena include factors such as efficiency and depth of distribution channels, marketing capabilities and name recognition. The location-based services and mobile commerce market is in its early stages. The Company believes that there will be several categories of competitors for its products and services. These include both network-based and GPS-based geo-location position determination equipment providers, wireless switch providers, wireless carriers and applications software providers. These companies include: TruePosition, Inc., the Grayson Wireless division of Allen Telecom, Inc., Cell-Loc, Inc., Cambridge Positioning Systems, SCC, SiRF Technology, Inc., SignalSoft Corp., the XYPoint division of TeleCommunication Systems, Inc., the SnapTrack, Inc. division of Qualcomm, Inc., Alcatel, Ericsson, Nortel, Motorola Inc., Verizon Wireless, Cingular Wireless, Sprint, AT&T Wireless, Voicestream Wireless, Airbiquity, Inc., and others. Many of these competitors are substantially larger and have longer operating histories, greater name recognition, larger customer bases, and substantially greater financial, marketing, technical and other resources than the Company. See generally "Business Risks -- Competition" below for a more detailed description of the risks and uncertainties associated with competition involving the Company and its current and future products and services. Manufacturing and Third-Party Vendors The Company has been and will continue to be dependent on third-party vendors for the computer equipment, electronic components, manufacturing services, maintenance services and software that are incorporated in its products. While these are generally available from multiple sources, the Company currently obtains or licenses certain equipment, electronic components, manufacturing services, maintenance services and software from a limited number of suppliers. The Company's current software products are specifically designed to adhere to the 10

UNIX operating system standard that can operate on standard computer equipment sold by numerous manufacturers and vendors. The Company currently purchases hardware and maintenance services directly or indirectly from Hewlett-Packard Company, its primary system hardware supplier. The Company also maintains relationships with other hardware vendors. The Company currently purchases hardware components from its vendors at discounts from list prices. These hardware components then become a cost component as the Company's systems are generally priced as bundled turnkey products (system, components, installation and training). The Company also currently maintains various software license arrangements with several suppliers. All of these licenses allow the Company's customers to use the software in perpetuity, with the result that the loss of a particular source would not affect any product already in use. The Company manufactures, as necessary, its proprietary Blackbird Cell Site System hardware that operates in connection with the hardware components described above. While certain parts and components of this system are industry standard and generally available from many suppliers, the Company designs and contracts manufacturing for certain proprietary printed circuit boards and other subassemblies. These standard components and custom manufactured subassemblies are then integrated and tested by the Company for delivery to the Company's customers. See also "Business Risks -- Risk of Hardware Manufacturing Activities" below. In connection with its prepaid phone card products, the Company has been and will continue to be dependent on third-party long-distance telephone service providers and their resellers for a package of accurate, reliable and competitively-priced telecommunications services, access numbers, PIN codes and, in some cases, prepaid phone cards produced by third parties. While these components are generally available from multiple sources, the Company currently acquires them from a relatively limited number of suppliers. See also "Business Risks -- Dependence on Third-Party Vendors" below. Proprietary Rights The Company's success will depend, in part, on its ability to protect its technology, processes, trade secrets and other proprietary rights from unauthorized disclosure and use and to operate without infringing the proprietary rights of third parties. The Company's strategy is to protect its technology and other proprietary rights through patents, copyrights, trademarks, nondisclosure agreements, license agreements and other forms of protection. The Company has been active in pursuing patent protection for technology and processes involving its products that it believes to be proprietary and to provide a potential competitive advantage for the Company. To date, the Company owns 14 issued United States patents relating to its products. In addition, the Company has also licensed patents from third parties in an effort to maintain flexibility in the development and use of its technology, including exclusive and non-exclusive rights to use patents in connection with the Blackbird Platform Products. The Company also attempts to protect its proprietary rights through the use of nondisclosure agreements with its employees and consultants, and license agreements with customers, which contain restrictions on disclosure, use and transfer of proprietary information. The Company further employs various physical security measures to protect its software source codes, technology and other proprietary rights. See also "Business Risks -- Uncertainty Regarding Proprietary Rights" below. Employees As of February 28, 2001, the Company had 47 employees. None of the Company's employees are covered by a collective bargaining agreement. The Company believes that its relations with its employees are good. See also "Business Risks- Dependence on Personnel" below. Business Risks The Company operates in a dynamic and rapidly changing business environment that involves substantial risk and uncertainty. The following discussion addresses some of the risks and uncertainties that could cause, or contribute to causing, actual results to differ materially from those expressed or implied in this report or any other disclosures 11

or statements, oral or written, made by or on behalf of the Company. Readers should pay particular attention to the descriptions of risks and uncertainties described below and in other sections of this report and the Company's other filings with the Securities and Exchange Commission. Dependence on Limited Product Base; Uncertainty of Widespread Market Demand. The Company's revenues and profits have been and can be expected to continue to be derived from a limited number of products and services. See "Business -- Major Customers" above. In part, the Company's future operating results will depend on the continued demand for Blackbird Platform Products. Currently, a majority of the carriers in the largest markets in the United States are using cloning fraud prevention products. The Company believes that the demand for cloning fraud prevention products in the United States will continue to decline in the future. If not offset by other sales opportunities, this trend would have a material adverse effect on the Company's revenue. The Company anticipates that its prepaid phone card products will account for a growing percentage of the Company's revenue in 2001. As a result, the Company's future operating results will depend on the demand for and market acceptance of prepaid phone card products. The market adoption and profitability of the Company's prepaid phone card products will need to increase in order to achieve the Company's income targets for that product line. Although the Company believes that its product and services present the basis for growth for the Company's business, there can be no assurance that its products and services will achieve widespread market penetration or that the Company will derive significant revenues or profits from the sale of such products and services. Dependence on Analog Networks; Industry and Technological Change. The Company's future success will depend on the continued and expanded use of its existing products and services, its ability to develop new products and services to meet the needs of the Company's target industries, and its ability to adapt existing products and services to keep pace with changes in the Company's target industries. Presently, the Company's Blackbird Platform Products are used exclusively in analog networks, although the Company believes that certain of the technology from its Blackbird Platform Products may be adaptable for use in digital networks in the future. The Company believes that a majority of wireless telephone subscribers in the United States use analog networks today, but that the industry is undertaking a shift to digital networks due to certain advantages of digital technology, including expanded capacity, greater privacy and enhanced security. In addition, alternative cloning fraud prevention products are available in both digital and analog networks, such as A-Key authentication. See "Business -- Competition" above. The Company expects that A-Key authentication will be widely deployed in digital networks over time. Accordingly, the Company does not believe that wireless telephone carriers will purchase RF fingerprinting fraud prevention solutions, such as the Blackbird Platform Products, for their digital networks unless and until the encryption technology that forms the basis for A-Key authentication is compromised. The shift from analog networks to digital networks, the expanded use of alternative cloning fraud prevention technologies such as A-Key authentication, and other technological developments in the wireless communications industry, could each reduce or eliminate demand for the Company's Blackbird Platform Products. There can be no assurance that the Company will be successful in modifying or developing its existing or future products in a timely manner, or at all, to respond to changing market, customer or technological requirements. If the Company is unable, due to resource, technological or other constraints, to adequately anticipate or respond to changing market, customer or technological requirements, the Company's business, financial condition and results of operations will be materially adversely affected. Further, there can be no assurance that products or services developed by others will not render the Company's products and services non-competitive or obsolete. Dependence on New Product Development and Product Enhancements. The Company's future success will depend, in part, on its ability to timely develop, introduce and gain acceptance of new products and services and enhancements to existing products and services to meet the needs of the Company's target industries. The Company is continually seeking to enhance its existing products and to develop new products. However, the Company remains subject to all of the risks inherent in product development, including unanticipated technical or other development problems that could result in material delays in product introduction and acceptance or significantly increased costs. There can be no assurance that the Company will be able to successfully enhance existing products or develop new products, or to timely introduce and gain acceptance of such enhancements and new products in the marketplace. 12

Ability to Manage Changing Business Conditions. The Company's future operating results will depend, among other things, on its ability to manage changing business conditions. If the Company's management is unable to do so effectively, its business, financial condition and results of operations could be materially adversely affected. The Company's ability to manage changing business conditions depends, in part, on its ability to attract, train and retain a sufficient number of qualified personnel to meet the ongoing needs of the Company. During 1998 and 1999, the Company implemented a restructuring plan that included, among other initiatives, reducing its workforce by approximately 80% from December 1997 staffing levels. Failure to properly manage the effects of such activity may limit the Company's ability to attract, train and retain qualified personnel and may increase the Company's recruiting and training costs. If the Company is unable to recruit and retain a sufficient number of qualified personnel, it could be forced to limit its growth or possibly curtail its operations. There can be no assurance that the Company will be successful in attracting, training and retaining the required number of qualified personnel to support the Company's business in the future. Failure to manage the Company's operations with the reduced staffing levels discussed above may further strain the Company's management, financial and other resources, and could have a material adverse effect on the Company's business, financial condition and results of operations. Limited Customer Base; Reliance on Significant Customers. The Company's potential customer base is relatively limited due to the significant concentration of ownership and/or operational control of telecommunication markets. Currently, the Company markets its Blackbird Platform Products only to wireless communications carriers that operate analog networks. Historically, a significant portion of the Company's revenues in any given period has been attributable to a relatively small number of customers. This trend is likely to continue for the foreseeable future. Sales to customers aggregating 10% or more, either individually or combined as affiliates due to common ownership, were concentrated as follows: one customer whose purchases represented 24% of consolidated 2000 sales, four customers whose purchases represented 46%, 21%, 14% and 12% of consolidated 1999 sales and three customers whose purchases represented 41%, 20% and 19% of 1998 sales. The aggregate sales to these customers represented 24% and 93% of the Company's consolidated phone card, systems and service revenues in 2000 and 1999, respectively, and 80% of the Company's total systems and service revenues in 1998. There can be no assurance that such customers will continue to maintain business relationships with the Company. Accordingly, the loss of one or more major customers could have a material adverse effect on the Company's business, financial condition and results of operations. Competition. The market for the Company's products and services is highly competitive and subject to rapid technological change, regulatory developments and emerging industry standards. A number of companies currently offer one or more products or services similar to the products and services offered by the Company. In addition, many carriers and vendors of telecommunications products are or may be capable of developing and offering products and services that are competitive with the Company's current products and services or any new products or services that the Company may offer in the future. See "Business -- Competition" above. The Company believes that, among other competing technologies, A-Key authentication poses significant future competition for the Blackbird Platform Products in the cloning fraud prevention arena. See "Business -- Competition" above. The Company believes the demand for its Blackbird Platform Products would be materially adversely affected if wireless communications carriers implement A-Key authentication applicable to analog phones as their sole or major cloning fraud prevention solution in major markets, if wireless communications carriers adopt a uniform digital standard that reduces the need for digital phones to operate in analog mode while roaming, or if analog phone manufacturers change product designs and/or manufacturing standards in such a way as to impact the performance of the Blackbird Platform Products. See also "Business Risks -- Dependence on Analog Networks; Industry and Technological Changes" above. The Company also is aware of many competitors which currently or are expected to compete directly with the Company's prepaid phone card products. The market for prepaid phone cards in the United States is increasingly competitive. In part, the Company competes with the long-distance telecommunications service providers as well as their service resellers, including service providers and resellers for whom the Company resells prepaid long-distance telephone services through its prepaid phone card products. Many of these competitors, including AT&T Corp., 13

MCI WORLDCOM, Inc., and Sprint Corporation, are substantially larger and have longer operating histories, greater name recognition, larger customer bases, and substantially greater financial, marketing, technical and other resources than the Company. In addition, trends in the telecommunications industry, including greater consolidation and technological or other developments that make it simpler or more cost-effective for telecommunications carriers to provide certain services themselves, could affect demand for the Company's products and services and could make it more difficult for the Company to offer a cost-effective alternative to a carrier's own capabilities. Current and potential competitors have established or may in the future establish collaborative relationships among themselves or with third parties, including third parties with whom the Company has a relationship, to increase the visibility and utility of their products and services. Accordingly, it is possible that new competitors or alliances may emerge and rapidly acquire significant market share. In addition, the Company anticipates continued growth in the telecommunications industry and, consequently, the entrance of new competitors in the future. An increase in competition could result in price reductions and loss of market share and could have a material adverse effect on the Company's business, financial condition and results of operations. To remain competitive, the Company will need to continue to invest in engineering, research and development, sales and marketing, customer service, manufacturing activities and administrative systems. There can be no assurance that the Company will have sufficient resources to make such investments or that the Company will be able to make the technological advances necessary to remain competitive. Many of the Company's current and potential competitors have significantly greater financial, marketing, technical and other competitive resources, as well as greater name recognition, than the Company. As a result, the Company's competitors may be able to adapt more quickly to new or emerging technologies and changes in customer requirements or may be able to devote greater resources to the promotion and sale of their products and services. There can be no assurance that the Company will be able to compete successfully with its existing competitors or with new competitors. Uncertainty Regarding Proprietary Rights. The Company's success will depend in part on its ability to protect its technology, processes, trade secrets and other proprietary rights from unauthorized disclosure and use and to operate without infringing the proprietary rights of third parties. The Company's strategy is to protect its technology and other proprietary rights through patents, copyrights, trademarks, nondisclosure agreements, license agreements and other forms of protection. See "Business -- Proprietary Rights" above. Patents issued and patent applications filed relating to products used in the Company's target industries are numerous, and the patent positions of companies in these industries, including the Company, are generally uncertain and involve complex legal and factual issues. Accordingly, there can be no assurance that any pending or future patent application of the Company or its licensors will result in issuance of a patent or that, when a patent does issue, that the scope of protection of the patent will be sufficiently broad to protect the Company's technology or provide a competitive advantage for the Company. There can be no assurance that any issued patent will not be challenged, invalidated or circumvented. Litigation or regulatory proceedings, which could result in substantial cost and uncertainty to the Company, may be necessary to enforce patent or other proprietary rights of the Company or to determine the scope and validity of a third-party's proprietary rights. There can be no assurance that the Company will succeed or will have the resources necessary to succeed in any such litigation or regulatory proceedings. Although the Company believes that its technology has been independently developed and that its products do not infringe patents known to be valid or violate other proprietary rights of third parties, it is possible that such infringement of existing or future patents or violation of proprietary rights may occur. There can be no assurance that the Company is aware of all third-party proprietary rights that may materially affect the Company's ability to make, use or sell its current or future products and services. United States patent applications, for example, are confidential while pending at the United States Patent and Trademark Office, and the laws of many foreign countries do not protect proprietary rights to the same extent as the laws of the United States. There can be no assurance that third parties will not assert infringement claims with respect to the Company's current or future 14

products or services, or that any such claims will not result in litigation or regulatory proceedings or require the Company to modify its products or enter into licensing arrangements, regardless of the merits of such claims. See "Business Risks -- Risk of Litigation" below. No assurance can be given that the Company will have the resources necessary to successfully defend against any such infringement claims or that any necessary licenses can be obtained in a timely manner, upon commercially reasonable terms, or at all. Parties making such infringement claims may be able to obtain injunctive or other equitable relief that could effectively limit or prohibit the Company's ability to make, use or sell its current or future products or services. The Company's failure to successfully defend against any such claims or obtain any such license could result in substantial cost and uncertainty to the Company and have a material adverse effect on the Company's business, financial condition or results of operations. The Company employs various physical security measures to protect its software source codes, technology and other proprietary rights. However, such measures may not afford complete protection and there can be no assurance that others will not independently develop similar source codes, technology or other proprietary rights or obtain access to the Company's software codes, technology, or other proprietary rights. In addition, although the Company has and expects to continue to have internal nondisclosure agreements with its employees and consultants and strategic partners, and license agreements with customers, which contain restrictions on disclosure, use and transfer of proprietary information, there can be no assurance that such arrangements will adequately protect the Company's proprietary rights or that the Company's proprietary rights will not become known to third parties in such a manner that the Company has no practical recourse. The Company's failure to successfully defend against any such claims or obtain any such license could result in substantial cost and uncertainty to the Company and have a material adverse effect on the Company's business, financial condition or results of operations. Risk of Litigation. From time to time, the Company may be a party to legal proceedings, which may or may not be in the ordinary course of business and which may have a material adverse effect on the Company's business, financial condition or results of operations. No such proceedings are currently pending. Need for Additional Financing. The Company's needs for additional financing will depend upon a number of factors, including, but not limited to, the commercial success of the Company's existing products and services, the timing and success of new products and services (if any), the progress of the Company's research and development efforts, the Company's results of operations, the status of competitive products and services, and the timing and success of potential strategic alliances or acquisitions of businesses, technologies or assets. In addition, the Company historically has experienced uneven cash flow and operating results, and, during two of the past four years, significant operating losses. The Company believes the combination of existing cash reserves and projected cash flow from operations will provide sufficient cash to fund its operations for at least the next 12 to 18 months. However, if the Company is unable to maintain profitability or achieves sales growth requiring working capital beyond current amounts, the Company may be required to seek additional financing sooner than currently anticipated or may be required to curtail some of its activities. There can be no assurance that additional financing will be available on acceptable terms, or at all. The Company's failure to obtain such additional financing, if needed, could have a material adverse effect on the Company's business, financial condition and results of operations. Fluctuations in Quarterly Performance. The Company has experienced fluctuations in its quarterly operating results and anticipates that such fluctuations may continue and/or intensify. The Company's quarterly operating results may vary significantly depending on a number of factors, such as : dependence on analog cellular networks for certain products and services; vulnerability to rapid industry change and technological obsolescence; changes in regulations affecting the wireless industry; limited customer base and reliance on a relatively small number of customers and customer contracts; dependence on a limited number of existing products and services; uncertainty of continued demand for and market penetration of its existing products and services under existing and future contracts; long sales cycles; uncertainty in its ability to timely develop, introduce and gain acceptance of new products and services; uncertainty of the demand for and market penetration of new products and services; the possible impact of competitive products and pricing; the risk that its current and future products may contain errors 15

or be affected by technical problems that would be difficult and costly to detect and correct; manufacturing difficulties, including reliance on a limited number of outside vendors for key components and processes; potential difficulties in managing changing business conditions; dependence on key personnel; the availability of financing; changes in the Company's operating expenses; uneven revenue streams; the timing of payments by customers; the Company's revenue recognition practices and policies; and general economic conditions. There can be no assurance that the Company's results of operations will not vary significantly among quarterly periods or that in future quarterly periods the Company's results of operations will not be below prior results or the expectations of public market analysts and investors. Volatility of Stock Price. The market for the Company's common stock is highly volatile. The trading price of the Company's common stock has been and could continue to be subject to wide fluctuations in response to quarterly variations in operating and financial results, announcements of technological innovations or new products by the Company or its competitors, changes in prices of the Company's or its competitors' products and services, changes in the Company's revenue and revenue growth rates, changes in the Company's stock market listing status, as well as other events or factors. See "Business Risks -- Fluctuations in Quarterly Performance" above. Statements or changes in opinions, ratings, or earnings estimates made by brokerage firms or industry analysts relating to the markets in which the Company competes have resulted, and could in the future result, in an adverse effect on the market price of the Company's common stock. In addition, the stock market has from time to time experienced extreme price and volume fluctuations which have particularly affected the market price for the securities of many high technology companies and which often have been unrelated to the operating performance of these companies. These broad market fluctuations may adversely affect the market price of the Company's common stock. History of Net Losses; Accumulated Deficit. As of December 31, 2000, the Company had an accumulated deficit of $21.7 million, the majority of which has accumulated during the three years ended December 31, 1998. See Part II, Item 7, entitled "Management's Discussion and Analysis of Financial Condition and Results of Operations" below for a more detailed description of the Company's accumulated deficit and history of net losses. There can be no assurance that the Company's operations will be profitable on a quarterly or annual basis in the future or that existing revenue and earnings levels can be enhanced or sustained. Past and existing revenue levels should not be considered indicative of future operating results. Operating results for future periods are subject to numerous risks and uncertainties, including those specified elsewhere in this report. If the Company is not successful in addressing such risks and uncertainties, the Company's business, financial condition and results of operations will be materially adversely affected. Dependence on Personnel. The Company's future success depends in large part on its ability to continue to attract, motivate and retain highly qualified personnel, particularly the members of its senior management and certain other employees who may be difficult to replace. Competition for such personnel is intense and there can be no assurance that the Company will be successful in attracting, motivating and retaining key personnel. The Company also believes stock options are a critical component for motivating and retaining its key personnel. The decline in the Company's stock price during the past three years has made stock options previously granted with higher exercise prices less valuable to the Company's current employees and has consequently made it more difficult for the Company to retain its key personnel. The inability to hire and retain qualified personnel or the loss of the services of key personnel could have a material adverse effect upon the Company's business, financial condition and results of operations. The Company does not maintain any key-man life insurance policies on any of its employees. Adequate Staffing Levels and Management of Growth. The Company's accounting and financial requirements have become more complex with the addition of its ISIS business and this trend is expected to continue as its Neumobility products reach the marketplace. The Company's failure to adequately recruit, hire, train and retain sufficient qualified staff to enable proper financial and accounting control of the Company's growth could have a material adverse effect on the Company's business, financial condition and results of operations. Risk of Hardware Manufacturing Activities. For the most part, the Company's engineering resources historically 16

have been devoted to software design and development. As a result, only a limited number of such resources were initially used in the design and prototype production of the Company's proprietary hardware. The Company continues to utilize third-party vendors for hardware design, engineering, manufacturing and integration of certain proprietary printed circuit boards, radio equipment and other subassemblies that are components of the Company's Blackbird Platform Products. The Company will continue to depend on third-party vendors for manufacturing activities with respect to the design and engineering of hardware, and its future success will depend on maintaining relationships with such third-party vendors, improving its inventory control systems, maintaining effective quality control and procuring sufficient quantities of component parts. Failure to achieve any of these factors could have a material adverse effect on the Company's business, financial condition and results of operations. Dependence on Third-Party Vendors. The Company has been and will continue to be dependent on third-party vendors for a variety of components incorporated in its products and services, including such items as quality long-distance service and related telecommunications services, competitive end-user rates and wholesale discounts, accurate and reliable access numbers and PIN codes, prepaid phone cards, computer equipment, network services, component parts, manufacturing services, maintenance services, systems integration and certain software. While available from multiple sources, some of these items are obtained from a single supplier or a limited number of sources. Although the Company believes that there are currently available substitute sources for all of these items, the Company could be required to redesign or modify affected products to accommodate for substitutions. The Company's reliance on third-party suppliers generally, and a sole or a limited number of sources in particular, involves several risks, including financial condition of the suppliers and a potential inability to obtain an adequate supply of required components and reduced control over quality, pricing and timing of delivery of components. There can be no assurance that the Company will be able to procure necessary components on a satisfactory and timely basis. Any failure or delay in obtaining necessary components or, if necessary, establishing alternative procurement arrangements, could cause delays in product commercialization and could require product redesign or modification. There can be no assurance that the Company could complete any necessary modifications in a timely manner or that modified or redesigned products would maintain current functionality or performance features or could be successfully commercialized. Any inability or delay in establishing necessary procurement arrangements or successfully modifying products could have a material adverse effect on the Company's business, financial condition and results of operations. Dependence on Distributors. The Company's Blackbird Platform Products are currently marketed primarily through the Company's direct sales efforts. However, its prepaid phone card products are currently marketed through multiple distribution channels. The Company believes that its dependence on distributors and these other sales and marketing relationships will increase in the future, both with respect to its prepaid phone card products and any new products and services that the Company may offer in the future. There can be no assurance that any existing or future distributors or other sales and marketing partners will not become competitors of the Company with respect to its prepaid phone card products or any new products and services, either by developing their own competitive products and services or by distributing the competitive offerings of others. Any failure by the Company's existing and future distributors or other sales and marketing partners to generate significant revenues could have a material adverse effect on the Company's business, financial condition and results of operations. Risk of Product Defects. It is common for hardware and software as complex and sophisticated as that incorporated in the Company's products and services to experience errors or "bugs" both during development and subsequent to commercial deployment. In particular, the Company has encountered certain software and hardware errors in its Blackbird Platform Products and to date corrected the majority, but not all, of such errors identified to date. There can be no assurance that any errors in the Company's existing or future products will be identified, and if identified, corrected. Any such errors could delay additional installations of products and require modifications in products that have already been installed. Remedying such errors has been and may continue to be costly and time consuming. Delays in remedying any such errors could materially adversely affect the Company's competitive position with respect to existing or new products offered by its competitors. Once the Company's products are installed, they are subject to compliance with certain contractual requirements, which may include acceptance testing to ensure that they are properly installed and performing in accordance with contractual specifications. 17

While the Company has achieved acceptance of a substantial number of products shipped to date, there can be no assurance that current or future installations of the Company's products will satisfy all contractual requirements. In addition, product warranties are generally included as part of the Company's contractual obligations. To the extent that available support or maintenance fees from its products are not adequate to cover the costs of making any necessary modifications or meeting the Company's warranty obligations, the Company could be required to make significant additional expenditures, which could have a material adverse effect on the Company. Risk of System Failure. The Company operates and maintains internal computers and telecommunication equipment for, among other things, monitoring and supporting its products and services and operating its No Clone Zone roaming fraud prevention service. The Company's operations are dependent upon its ability to maintain such equipment and systems in effective working order and to protect them against damage from fire, natural disaster, power loss, communications failure, unauthorized entry or other events. Although the Company provides back up for substantially all of its systems, these measures do not eliminate the risk to the Company's operations from a system failure. In addition to its own systems, the Company relies on certain equipment, systems and services from third parties that are also subject to risks, including risks of system failure. There can be no assurance that the Company's property and business interruption insurance will be adequate to compensate the Company for any losses that may occur in the event of a system failure. Any damage, failure or delay that causes interruptions in the Company's operations could have a material adverse effect on the Company's business, financial condition and results of operations. International Operations. To the extent that the Company pursues potential sales opportunities for its products and services in international markets, the Company is and will remain subject to all the risks inherent in international sales activities, such as lengthy sales cycles, high costs of sales, changes in export, import, tariff and other trade regulations, currency exchange rates, foreign tax laws and other legal, economic and political conditions. There can be no assurance that the occurrence of any of the foregoing will not have a material adverse effect on the Company's business, financial condition and results of operations. Further, the laws of certain foreign countries do not protect the Company's intellectual property to the same extent as the laws of the United States. See "Business Risks -- Uncertainty Regarding Proprietary Rights." In certain international markets, the Company will need to modify its products or develop new or additional products to adapt to the different wireless technologies or network standards utilized by the carriers in such markets. There can be no assurance that the Company's marketing efforts and technological enhancements will result in successful commercialization or market acceptance or penetration in such international markets. If the Company is unable to adequately anticipate and respond to marketing or technological requirements in the international marketplace, the Company's business, financial condition and results of operations could be materially adversely affected. Government Regulation and Legal Uncertainties. While, for the most part, the Company's operations are not directly regulated, certain of the Company's existing and potential customers, vendors and strategic alliance partners are subject to a variety of United States and foreign governmental laws, regulations and other requirements. The terms of any existing laws, regulations or other requirements, or any changes thereto, may inhibit the growth of the telecommunications industry, limit the number of potential customers for the Company's products and services and/or impede the Company's ability to offer competitive services to the telecommunications market or otherwise have a material adverse effect on the Company's business, financial condition and results of operations. Recently enacted federal legislation deregulating the telecommunications industry has caused and is expected to continue causing changes in the industry, including entrance of new competitors or industry consolidation, which could in turn subject the Company to increased pricing pressures, decrease the demand for the Company's products and services, increase the Company's cost of doing business or otherwise have a material adverse effect on the Company's business, financial condition and results of operations. Item 2. Properties The Company leases approximately 10,000 square feet of general office space in Seattle, Washington for its corporate offices under a three-year non-cancelable operating lease that expires in September 2003. The lease 18

contains renewal options and provides for the pass-through to the Company of increases in operating and other costs. The Company also has a lease for approximately 4,000 square feet of space in Seattle, Washington, for assembly, testing and general warehouse purposes expiring in December 2001, subject to certain early termination provisions. Additionally, the Company currently has four lease arrangements in connection with its prepaid phone card operations, which include a 15-month sublease for approximately 1,200 square feet of general office space in Lyndhurst, New Jersey expiring May 2001, a 16 month lease for approximately 1,200 square feet of general office space in Stoneham, Massachusetts expiring June 2001, a three-year lease for approximately 1,100 square feet of general office space in Hinsdale, Illinois expiring July 2003 and a three-year lease for approximately 1,700 square feet of general office space in Los Angeles, California expiring March 2003. Item 3. Legal Proceedings In January 2001 the Company filed an arbitration claim against CMT Partners, a Delaware general partnership d/b/a AT&T Wireless Services for breach of contract and recovery of approximately $900,000 of damages, plus attorneys' fees and costs. The arbitration is scheduled to be completed during the second quarter of 2001. The Company believes it has a strong position in this matter, however, the outcome of such arbitration cannot be predicted. From time to time, the Company may be a party to legal proceedings, which may or may not be in the ordinary course of business and which may have a material adverse effect on the Company's business, financial condition or results of operations. No such proceedings are currently pending. Item 4. Submission of Matters to a Vote of Security Holders There were no matters submitted to a vote of security holders of the Company, through solicitation of proxies or otherwise, during the fourth quarter of the fiscal year covered by this Annual Report. 19

PART II Item 5. Market for Registrant's Common Equity and Related Stockholder Matters The following table sets forth, for each quarter during fiscal 1998 and 1999 and for the period from January 1, 2000 through March 12, 2000, the reported high and low sales prices of the Company's Common Stock on The Nasdaq Stock Market (National Market System) (Symbol: "CTSC"). Prices and the number of shares of the Company's common stock described in this Item 5 have been adjusted to give effect to the one-for-ten stock combination (reverse stock split) described in this report, which was consummated as of January 5, 1999. Sales Price ----------- High Low ---- --- 1999 ---- First Quarter 4.38 1.88 Second Quarter 12.00 1.69 Third Quarter 6.25 3.25 Fourth Quarter 13.50 3.19 2000 ---- First Quarter 18.56 7.56 Second Quarter 16.38 6.75 Third Quarter 11.38 7.06 Fourth Quarter 8.50 2.22 2001 ---- First Quarter through March 12, 2001 7.00 2.59 As of March 12, 2001, the number of holders of record of the Company's Common Stock was 202, and the number of beneficial shareholders was estimated to be in excess of 4,700.

Overview The Company develops, markets, distributes and supports a diversified mix of products and services for the telecommunications industry. Over the past 12 years, the Company has developed expertise in real-time wireless call processing and has created technologically advanced solutions for this industry, focusing primarily in the area of wireless communications fraud management. During 1999 and 2000, the Company implemented a short and long-range strategic plan to diversify its product mix, both within and outside of the telecommunications industry. This diversification strategy is at the foundation of the Company's growth plan for the future. Products The Blackbird Platform Products The Company's Blackbird'r' Platform product line includes a suite of radio frequency ("RF") based platform solutions focusing on wireless fraud prevention. Presently, it involves various forms of "pre-call" verification to ensure that the use of an analog wireless telephone is legitimate before the device is allowed to connect to a carrier's analog wireless communications network. In this area, the Company is a leading provider of RF-based solutions for the prevention of "cloning fraud." This term is used to describe the illegal activity of using a scanning device to steal the electronic serial number and mobile identification number of a legitimate wireless telephone while in use, then reprogramming the stolen numbers into other phones. These reprogrammed phones, or "clone phones," are then used to make illegal calls on a wireless communications network, without payment for the wireless services rendered. The Company's suite of RF-based platform solutions include the Blackbird'r' Platform, PreTect'TM' cloning-fraud prevention application, No Clone Zone'sm' roaming-fraud prevention service, and related application products and services (collectively, the "Blackbird Platform Products"). The Company's Blackbird Platform Products are currently deployed in approximately 1,600 cell sites in most major metropolitan areas throughout the United States. The Company's customers have reported up to a 98% reduction in cloning fraud activity in areas served by the Blackbird Platform Products since its initial installation, and continue to rely on its cloning prevention capabilities for their existing analog wireless communications networks. 22

Prepaid Wireline Long-Distance Phone Cards To stimulate revenue growth for the Company, and in alignment with its product diversification strategy, the Company expanded into the prepaid long-distance service arena in the fourth quarter of 1999. Through its new majority-owned subsidiary, Isis Tele-Communications, Inc., the Company markets and distributes branded prepaid long-distance phone cards in denominations generally ranging from $5 to $20 per card. Isis specializes in targeted marketing programs and features local and toll-free access numbers and aggressive domestic and international long-distance rates. Isis distributes cards through regional and national multi-level distribution channels, using direct sales, third party distributors and telemarketing. The Company anticipates that its ability to provide aggressive per-minute rates, broad multi-level distribution coverage, and quality customer service will provide the key ingredients to fueling revenue growth and future product expansion of this product line for the Company. Isis has sales offices in Los Angeles, Boston and Chicago. Geo-Location Wireless Applications Investment and Product Development The Federal Communications Commission ("FCC") has required all wireless carriers to deploy wireless geo-location technology by October 2001 to provide comparable 911 services to wireless telecommunications subscribers. Wireless geo-location technology provides and identifies the specific geographic location (in latitude and longitude measurements) of a wireless telephone, and can eventually be applied to other wireless communications devices. Industry analysts have estimated the market for commercial geo-location applications to be well over $8.0 billion. During the fourth quarter of 1999, and as part of the Company's long-term diversification strategy, the Company made a strategic investment in KSI, Inc. ("KSI"), a provider of development-stage wireless geo-location technology. In August 2000, TruePosition, Inc., a subsidiary of Liberty Media Corporation, acquired KSI. The Company's total investment in TruePosition, Inc. common at December 31, 2000 was $1,758,000. In late 1999 the Company began development of a location-based wireless software product platform and mobile commerce applications. The Company expects to leverage its entrance into the geo-location marketplace by developing, marketing, distributing, and supporting a suite of commercial geo-location applications as the technology evolves and is deployed by all wireless carriers to comply with the FCC's requirements. In January 2001 the Company formed a division called Neumobility'TM' for this product line. The Neumobility family of products includes a scalable platform and an application suite providing location-based information utilizing both network and satellite positioning technologies. The platform is called NeuTrac'TM', and is a system utilizing positioning data to create, maintain and deliver relevant content and services in a location-based format. The NeuTrac platform is configurable and creates a combination of subscription-based, pay-per-use and free value-added services. The application suite will include: NeuCommerce'TM', which allows for personalized, permission-based one-to-one marketing; NeuMerchant'TM', which allows for the tracking of merchant offers and creates metrics to analyze the impact of marketing efforts; NeuMap'TM', which creates directions based upon positioning data; NeuList'TM', which adds a location-sensitive component to wireless e-mail functions; and NeuJournal'TM', a journaling feature which allows for the documentation of location and content. The Company anticipates completing the initial product suite in 2001. Revenue and Expense Revenue During 2000, the Company generated revenue through three sources: (i) Isis pre-paid phonecard product sales, (ii) Blackbird systems revenue, and (iii) Blackbird service revenue. Prepaid phone-card revenue is comprised of wholesale and retail sales of prepaid local, long-distance and wireless products. The revenue is recognized at shipment of product, net of reserves for estimated returns. The Company maintains an allowance for sales returns for prepaid phone cards based on estimated returns in accordance with 23

SFAS 48. Estimated returns, along with their costs, have been reflected as a reduction in sales and cost of goods sold, respectively, and reflected as a reduction in accounts receivable and an increase in inventory, respectively. Systems revenue is generated from licensing and sales of the Company's proprietary software and hardware products, the sale of third-party products sold in connection with the Company's proprietary products and, to a lesser extent, fees earned in connection with the installation and deployment of these products. Revenue is recognized when all of the following conditions are met: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred, including satisfaction of all contractual obligations, and other elements that are essential to the functionality of the delivered products have been satisfied; (iii) the amount is fixed or determinable; and (iv) collectability is probable. Revenue is deferred if the above conditions are not met, based on vendor specific objective evidence ("VSOE") of the fair value for all elements of the arrangement. VSOE is typically based on the price charged when an element is sold separately, or, in the case of an element not yet sold separately, the price established by authorized management, if it is probable that the price, once established, will not change before market introduction. Elements included in multiple element arrangements could consist of software products, upgrades, enhancements, customer support services, or consulting services. Service revenue is derived primarily from hardware and software maintenance programs, No Clone Zone roaming fraud prevention service, Blackbird Platform Monitoring service and related professional services provided in support of the Company's currently deployed product base. Service revenue is recognized ratably over the period that the service is provided. Hardware and software maintenance generally begins after system acceptance. Prepaid or allocated maintenance and services are recorded as deferred revenue. Revenue recognition for the Company's systems varies by customer and by product. Every element of a contract must be identified and valued based upon VSOE, regardless of any stated price in the contract. Revenue from any undelivered elements of a contract is deferred. However, any undelivered element essential to the functionality of the delivered product will cause a 100% deferral of the sale. Amounts billed and received on sales contracts before products are delivered or before revenue is recognized or recognizable are recorded as customer deposits or deferred revenue. Costs and Expenses Costs of phone cards, systems and services are primarily comprised of the costs of: (i) prepaid phone card costs; (ii) equipment, including both proprietary and third-party hardware and, to a lesser extent, manufacturing overhead and related expenses; (iii) amortization of capitalized software development costs; (iv) systems integration and installation; (v) royalty fees related to the licensing of intellectual property rights from others; (vi) customer support; and (vii) activities associated with the evaluation, repair and testing of parts returned from the field in connection with the Company's ongoing hardware maintenance service activities. Research and development expenditures include the costs for research, design, development, testing, preparation of training and user documentation and fixing and refining features for the software and hardware components included in the Company's current and future products and services. The Company expects that its costs and expenses in these and other areas will continue to be incurred in the future, due to the ongoing need to: (i) make investments in research and development to enhance existing products and services and to develop new products and services to address emerging market opportunities, such as those in the geo-location and prepaid phone card markets; (ii) enhance its sales and marketing activities; (iii) enhance hardware 24

maintenance processes; (iv) enhance its customer support capabilities; and (v) enhance its general and administrative activities. Year ended December 31, 2000 compared to year ended December 31, 1999 Overview Total revenues increased 154% to $26.0 million in 2000 from $10.2 million in 1999, and the Company generated net income of $2.6 million, or $1.12 per basic share in 2000, compared to $2.6 million, or $1.14 per basic share in 1999. The Company recognized an alternative minimum tax expense of $58,000 in 2000 compared to $31,000 in 1999. As described below, the increased overall revenue was due to an increase in revenue from the Company's new ISIS Tele-Communications, Inc. subsidiary from prepaid long distance phone products, offset by a 22% decrease in combined sales and service revenue from the Company's Blackbird Platform Products. The Company attributes the lower revenue from its Blackbird Platform Products to: (i) a reduction in domestic market opportunities for the Company's cloning fraud prevention technology due to the effectiveness of this and other authentication-based products in combating cloning fraud; (ii) lower market penetration than originally planned of Company's cloning fraud prevention technology; and (iii) the lack of significant additional new sales of the Company's cloning fraud prevention technology in 2000. Revenue Phonecard revenue totaled $18.0 million in 2000. Revenue was $19,000 from sales of prepaid phone cards in 1999. Blackbird systems and service revenue decreased 22% to $7.9 million in 2000 from $10.2 million in 1999 due to the factors discussed above. Cost of Phonecards, Systems and Services Costs of phonecards, systems and services increased to $20.5 million in 2000 from $3.7 million in 1999. As a percent of total revenue, the costs were 79% and 37% for the 2000 and 1999 periods, respectively. The increase in the amounts and percentages of costs for 2000 relative to 1999 is primarily due to the prepaid phone card business being a larger percentage of the Company's overall business with lower gross margins compared to the Company's other products. Included in costs of goods sold for the Company's Isis subsidiary were write-offs related to bankruptcies of three of its suppliers during 2000 totaling approximately $1.3 million. Partially offsetting these increases in costs were decreases in amortization of capitalized software development costs and expense reductions relating to reduced headcount and consolidation of warehousing facilities. Operating Expenses Sales and marketing expenses increased to $1.4 million in 2000 from $0.7 million in 1999. As a percent of total revenue, the costs were 5% and 7% for the 2000 and 1999 periods, respectively. The increase in sales and marketing expenses is attributable to costs incurred in selling and marketing prepaid phone cards in 2000 offset by a decrease in sales and marketing expenses for the Blackbird Platform products. General and administrative expenses remained comparable at $2.1 million in 2000 and 1999. Research and development costs decreased to $1.5 million in 2000 from $1.6 million in 1999. The decrease in expenditures in 2000 was attributable to reduced staffing levels and related expenditures from the prior year period, partially offset by increased spending on product enhancements and new product research in the geo-location application technology area. Other Income, net 25

Other income was $1.7 million in 2000, compared to $0.3 million in 1999. The 2000 period included a net legal settlement of $1.5 million received by the Company and the 1999 period included a net state sales tax refund of $0.5 million. Interest Income, net Interest income increased to $0.4 million in 2000 from $0.3 million in 1999, resulting from higher average cash balances on hand and higher average interest rates earned on invested cash in 2000 compared to 1999. Year ended December 31, 1999 compared to year ended December 31, 1998 Overview Total revenues decreased 14% to $10.2 million in 1999 from $12.0 million in 1998 and the Company generated net income of $2.6 million, or $1.14 per basic share in 1999 compared to a net loss of $10.9 million, or $4.76 per basic share in 1998. The Company recognized an alternative minimum tax expense of $31,000 during the 1999 period. While the Company enjoyed increased service revenue, as described below, the Company attributes the total lower revenue to: (i) a reduction in domestic market opportunities for the Company's cloning fraud prevention technology due to the effectiveness of this and other authentication-based products in combating cloning fraud; (ii) lower market penetration than originally planned of Company's cloning fraud prevention technology; and (iii) the lack of significant additional new sales of the Company's cloning fraud prevention technology in 1999. The improved net income performance is attributable to: (i) cost reductions that included, among other initiatives, streamlining the Company's operations, reducing its workforce and consolidating its facilities; (ii) increased service revenue originating from an increased installed base of systems; (iii) reduced non-cash charges related to inventory reserves, software amortization and fixed asset write-offs; and (iv) increased interest income due to higher average cash balances on hand during 1999. Revenue Service revenue increased 14% to $8.6 million in 1999 from $7.5 million in 1998. Approximately 96% and 92%, respectively, of the 1999 and 1998 total service revenue was derived from Blackbird Platform Products. The increase in service revenue is largely attributable to a larger installed base of Blackbird Platform Products in 1999 as compared to 1998 and additional recurring services performed in 1999 as compared to 1998. Service revenues from Hotwatch Platform Products, which were phased out of commercial use in 1999, were not material in the 1999 period. Systems revenue decreased 63% to $1.6 million in 1999 from $4.4 million in 1998 due to the factors discussed above. Cost of Systems and Services Costs of systems and services, which primarily relate to the Company's Blackbird Platform Products, decreased 74% to $3.7 million in 1999 from $14.4 million in 1998. Costs of systems and services, as a percent of total revenue, were 37% and 120% for the 1999 and 1998 periods, respectively. The decrease in amounts and percentages for 1999 relative to 1998 reflects: (i) the full-year impact of cost reductions implemented in 1998; (ii) reduced inventory reserve additions and capitalized software amortization; (iii) increased service revenue in 1999, resulting from an increased leveraging of the Company's fixed customer support operating expenses; and (iv) lower costs associated with the decrease in systems revenue in 1999 as discussed above. 26

Operating Expenses Sales and marketing expenses decreased 20% to $0.7 million in 1999 from $0.9 million in 1998. The decrease in sales and marketing expense is attributable primarily to the full-year impact of reductions in average staffing levels and related expenses resulting from the cost reductions implemented in 1998. General and administrative expenses decreased 19% to $2.1 million in 1999 from $2.6 million in 1998 and primarily reflect the full-year impact of a reduction in staffing levels and related expenses implemented in 1998. Research and development costs decreased 65% to $1.6 million in 1999 from $4.5 million in 1998. The decrease in expenditures in 1999 was primarily attributable to the full-year impact of reduced staffing levels implemented in 1998, partially offset by spending on product enhancements and new product research. Other Income, net Other income was $0.3 million in 1999 compared to a net expense of $0.5 million in 1998. A net state sales tax refund of $0.5 million was received in the 1999 period. Net losses on dispositions of fixed assets were $0.2 million in 1999 and $0.5 million in 1998. Interest Income, net Interest income increased to $0.3 million in 1999 from $0.1 million in 1998, resulting from higher average cash balances, interest income earned on customer accounts and interest earned on a state sales tax refund received in the 1999 period. Liquidity and Capital Resources The Company's capital requirements have historically consisted primarily of funding hardware and software research and development, property and equipment requirements, working capital and the Company's operating expenses. The Company has funded these requirements in recent years from operating profits and through issuance of common stock (including proceeds from the exercise of warrants and options). On December 31, 2000, the Company's cash balance was $4.5 million as compared to $4.8 million on December 31, 1999. The Company's working capital increased to $5.4 million at December 31, 2000 from $3.6 million at December 31, 1999. Excluding deferred revenue, working capital decreased to $5.8 million at December 31, 2000 from $6.7 million at December 31, 1999. Cash Provided by Operating Activities Cash provided by operating activities amounted to $1.0 million in 2000, compared to $4.2 million in 1999, and cash used in operating activities of $1.4 million in 1998. The major factor contributing to the Company's cash flow from operating activities in the 2000 period was the $2.6 million net income. The reduction from 1999 to 2000 primarily reflects the reduced level of deferred revenue at December 31, 2000. Cash Used in Investing Activities Cash used in investing activities totaled $1.3, $1.0 and $0.5 million in 2000, 1999 and 1998, respectively. In 2000 the Company invested $758,000 in common stock of KSI, Inc. The 2000 amount also included $0.7 million in equipment and leasehold improvement capital expenditures. In 1999 the Company invested $1.0 million in a convertible note receivable due from KSI, Inc., a provider of development-stage wireless geo-location technology. The note receivable and common stock were converted into common stock of TruePosition, Inc. during 2000. At December 31, 2000, the Company had no significant commitments for capital expenditures. Cash Provided By Financing Activities 27

Cash provided by financing activities resulting from the exercise of stock options totaling $43,000, $2,000 and $0 during 2000, 1999 and 1998, respectively. Operating Trends The Company earned $2.6 million for the year ended December 31, 2000, compared to $2.6 million for the year ended December 31, 1999 and an operating loss of $10.9 for the year ended December 31, 1998. As of December 31, 2000, the Company had an accumulated deficit of $21.7 million, which primarily accumulated during the three years ended December 31, 1998. During 1996 and 1997, the Company deployed its initial cloning fraud prevention Blackbird Platform Products and incurred substantial operating expenses during such deployment. During 1998, in response to unfavorable operating results, the Company implemented a restructuring plan that included, among other initiatives, streamlining the Company's operations to better balance expenses and revenues, and directing additional development efforts and resources towards new products to generate new sources of revenue. Through the end of 2000 the results of the Company's restructuring plan showed significant improvement in profitability and cash flow. There can be no assurance, however, that the Company's operations will be profitable on a quarterly or annual basis in the future or that existing revenue levels can be enhanced or sustained. Past and existing revenue levels should not be considered indicative of future operating results. While the Company believes that its current cash reserves and projected cash flow from operations provide sufficient cash to fund its operations for at least the next twelve to eighteen months, unanticipated changes in customer needs and/or other external factors may require additional financing and/or further expense reductions.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS The Board of Directors and Stockholders Cellular Technical Services Company, Inc. We have audited the accompanying consolidated balance sheets of Cellular Technical Services Company, Inc. as of December 31, 2000 and 1999, and the related consolidated statements of operations, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2000. Our audits also included the consolidated financial statement schedule listed in the Index at Item 14(a). These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Cellular Technical Services Company, Inc. at December 31, 2000 and 1999, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2000, in conformity with auditing standards generally accepted in the United States.

CELLULAR TECHNICAL SERVICES COMPANY, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NOTE A - NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES: Nature of Operations and Organization Cellular Technical Services Company, Inc. ("CTS") is primarily engaged in the design, development, marketing, installation and support of integrated information processing and information management systems for the domestic wireless communications industry, and through CTS' majority-owned subsidiary, Isis Tele-Communications, Inc. ("Isis"),in the domestic wireline phone card industry primarily as a distributor and a reseller. Isis commenced operations in December 1999. CTS acquired all of the outstanding shares of Communications Information Services, Inc. ("CISI") in August 2000. CISI had no revenue or expenses during 2000. Unless the context otherwise requires, all references to the "Company" herein include Cellular Technical Services Company, Inc. and any entity over which it has or shares operational control. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries. All inter-company accounts and transactions have been eliminated in consolidation. Estimates and Assumptions The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. Fair Values of Financial Instruments At December 31, 2000, the Company has the following financial instruments: cash and cash equivalents, accounts receivable, long-term stock investment, accounts payable and accrued liabilities. The carrying value of cash and cash equivalents, accounts receivable, stock investment, accounts payable and accrued liabilities approximates their fair value based on the liquidity of these financial instruments or based on their short-term nature. Diversification of Credit Risk The Company is subject to concentrations of credit risk primarily from cash investments and accounts receivable. Credit risk from cash investments is managed by diversification of cash investments among institutions and by the purchase of investment-grade commercial paper securities. The estimated fair values of the securities approximate cost. Credit risk associated with trade receivables is subject to ongoing credit evaluations. The Company does not typically require collateral for receivables. Reserves for potential losses, if any, are maintained where appropriate. 38

Inventories As of December 31, 2000 the Company determined that the remaining balance of telecommunications equipment of approximately $175,000 will be utilized only as repair parts in conjunction with its maintenance agreements servicing its installed customer base and will not be available for sale. The balance in inventory at December 31, 2000 was transferred to prepaid expenses and is being amortized over the expected remaining maintenance contract lives of 12 months. Phone card inventories are stated at the lower of cost or market value, with cost determined on a first-in, first-out basis. The Company monitors inventory for obsolescence and considers factors such as turnover, technical obsolescence and pricing. Reserves for slow-moving and obsolete inventory are maintained where appropriate. Property and Equipment Property and equipment, including leasehold improvements, are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization commences at the time assets are placed into service and is computed using the straight-line method over the shorter of estimated useful lives of the assets of two to five years or terms of the associated leases. The Company capitalizes expenditures that significantly increase the life of the related assets, while maintenance and repairs are charged to operations. Gain or loss is reflected in results of operations upon the retirement or sale of assets. Software Development Costs Software development costs consist primarily of internally developed software. Capitalization of software development costs begins upon the establishment of technological feasibility and ceases when products are completed. Amortization begins when products are available for general release. Amortization of capitalized software development costs is the greater of the amount computed using the ratio that current gross revenues for a product bear to the total of current and anticipated future gross revenues for that product, or the straight-line method over the remaining estimated economic life of the product, generally twenty-four months. At December 31, 2000, the Company's capitalized software costs were fully amortized. Long-Lived Assets Long-lived and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Impairment is measured by comparing the carrying value of the long-lived assets to the estimated future cash flows expected to result from use of the assets and their ultimate disposition. In circumstances where impairment is determined to exist, the Company will write down the asset to its fair value based on the present value of estimated expected future cash flows. Revenue Recognition The Company generates revenues through three sources: (1) prepaid phone card sales, (2) systems revenues, consisting primarily of bundled hardware and software products, and (3) services revenues, consisting primarily of hardware and software maintenance and related support services. Phone card revenues are recognized upon shipment, net of estimated returns. Costs of goods sold for phone cards include related shipping and handling costs. Systems revenues are recognized when all of the following conditions are met: (i) Persuasive evidence of an arrangement exists. (ii) Delivery has occurred. Delivery also includes satisfaction of contract criteria and that there are no additional undelivered elements essential to the functionality of the delivered products. Revenues are 39

deferred for undelivered non-essential elements based on vendor specific objective evidence ("VSOE") of the fair value for all elements of the arrangement. (iii) The amount is fixed and determinable. (iv) Collectability is probable. VSOE is typically based on the price charged when an element is sold separately, or, in the case of an element not yet sold separately, the price established by authorized management, if it is probable that the price, once established, will not change before market introduction. Elements included in multiple element arrangements could consist of software products, upgrades, enhancements, customer support services, or consulting services. Service revenues are recognized ratably over the period that maintenance coverage is provided. Prepaid or allocated maintenance and services are recorded as deferred revenues. Segment Reporting The Company's operations consist of two segments, integrated information processing and information management systems for the wireless communications industry, and phone-card distribution. Income Taxes The Company follows the deferred method of accounting for income taxes whereby deferred tax assets and liabilities are determined based on differences between financial reporting basis and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. The Company provides a valuation allowance for deferred tax assets that cannot be currently recognized due to the cumulative losses incurred by the Company. Net Earnings or Loss Per Share Basic earnings or loss per share is computed by dividing net earnings or loss by the weighted average number of common shares outstanding for the period. Diluted earnings or loss per share reflects the potential dilution of securities by including other common stock equivalents (i.e. stock options) in the weighted average number of common shares outstanding for a period, if dilutive. Other Comprehensive Income The Company has no items of comprehensive income or loss. Stock-Based Compensation The Company evaluates stock-based compensation in accordance with SFAS No. 123, "Accounting for Stock-Based Compensation" ("Statement 123"). As provided for by Statement 123, the Company has chosen to measure stock-based compensation cost under the intrinsic-value method prescribed under Accounting Principles Board Opinion No. 25 and has adopted only the disclosure provisions of Statement 123. As the Company issues options with exercise prices equal to market value on the date of grant, compensation expense is not recognized. Recent Accounting Pronouncements During June 1999, the FASB issued SFAS No. 137, Accounting for Derivative Instruments and Hedging Activities-Deferral of the Effective Date of SFAS 133. SFAS 137 defers the effective date of SFAS 133 to fiscal 2001. During June 2000, the FASB issued SFAS 138, Accounting for Certain Derivative Instruments and Certain Hedging Activities, which amends certain provisions of SFAS 133. The Company will adopt SFAS 138 40

concurrently with SFAS 133 on January 1, 2001. SFAS 133 establishes accounting and reporting standards that require every derivative instrument be in the balance sheet as either an asset or liability measured at its fair value. SFAS 133 also requires that changes in the fair value be recognized in earnings unless specific hedge accounting criteria are met. Because the Company has never used nor currently intends to use derivatives, management does not anticipate the adoption of this new standard will have a significant effect on the Company's financial position, results of operations or liquidity. In December 1999, the SEC issued Staff Accounting Bulletin Number 101 ("SAB 101"), Revenue Recognition in Financial Statements. SAB 101 provides guidance related to revenue recognition based on interpretations and practices recommended by the SEC. SAB 101 was effective for the year ended December 31, 2000, and required companies to report any changes in revenue recognition as a cumulative change in accounting principle. The adoption of SAB 101 did not have a significant impact on the Company's financial position, results of operations or liquidity. Risks and Uncertainties Management of the Company believes that the risks and uncertainties discussed below, whether viewed individually or combined, will not result in a significant unfavorable impact to the Company. However, there can be no assurance that any unfavorable outcome of the risks and uncertainties discussed below will not have a material adverse effect on the Company's financial position, results of operations or liquidity. Limited customer base; Reliance on significant customers: The Company's potential customer base is relatively limited due to the significant concentration of ownership and/or operational control of wireless communication markets. The nature of the Company's business is such that a single customer and its affiliates will account for more than 10% of the Company's phone card, product and service revenues during a given fiscal year. Sales to customers aggregating 10% or more, either individually or combined as affiliates due to common ownership, were concentrated as follows: one customer whose purchases represented 24% of consolidated 2000 sales, four customers whose purchases represented 46%, 21%, 14% and 12% of consolidated 1999 sales, and three customers whose purchases represented 41%, 20% and 19% of 1998 sales. The aggregate sales to these customers represented 24% and 93% of the Company's consolidated phone card, systems and service revenues in 2000 and 1999, respectively, and 80% of the Company's total systems and service revenues in 1998. There can be no assurances that such customers will continue to maintain business relationships with the Company. Accordingly, the loss of one or more major customers could have a material adverse effect on the Company. Limited vendor base; Reliance on small number of vendors: The Company purchases its phone cards from a limited number of long distance providers and is reliant on these providers to provide service for its customers. Three of its vendors filed for bankruptcy protection during 2000. Management has continually upgraded the quality of its phone card vendors, however, there can be no assurance that all of the vendors will continue to provide the level of service the Company requires. Liquidity; Possible need for financing: Going forward into 2001, the Company has continued to reduce its fixed operating costs. The Company has contracts for its recurring Blackbird service revenue extending through 2001. Management believes that under its current business plans, its current cash balances and cash flows expected to be generated from operations are sufficient to fund its operations and capital requirements through the next twelve to eighteen months. However, the Company's inability to successfully generate sufficient cash flow from operations would have a material adverse impact on the Company's financial position, liquidity or results of operations and may require the Company to reduce its expenditures further or curtail certain operations to enable it to continue its operations for that period. Legal proceedings: From time to time, the Company could be subject to involvement with legal actions and claims which arise in the ordinary course of business which management believes will be resolved without a material adverse effect on the Company's business, financial condition or results of operations. 41

Reclassifications Certain reclassifications have been made to the prior year financial statements to conform to the current period's presentation. NOTE B - INVENTORIES: Inventory reflects phonecards sold through the Company's phonecard business. Prior to December 31, 2000 the inventory included parts used in the systems and service business. At December 31, 2000, the net remaining systems and service parts inventory of $175,000 has been reclassified to other current assets, as it is no longer held for resale. The value of the items is being amortized over the shorter of the estimated remaining service lives of the parts or the underlying maintenance contract terms. Included in phone card inventory at December 31, 2000 is $87,000 related to 2000 sales that have been accounted for on consignment basis and $259,000 related to sales returns reserves. Inventory consists of the following (in 000's): December 31, ------------------------------ 2000 1999 -------------- -------------- Inventory, primarily service parts $ -- $ 1,589 Phonecards 1,123 -- Less reserves (27) (997) -------------- -------------- $ 1,096 $ 592 ============== ============== NOTE C - PROPERTY AND EQUIPMENT: Property and equipment consist of the following (in 000's): December 31, ------------------------------- 2000 1999 -------------- -------------- Computer equipment and software $ 3,339 $ 3,518 Furniture, fixtures and office equipment 466 588 Leasehold improvements 248 181 -------------- -------------- 4,053 4,287 Less accumulated depreciation and amortization (3,090) (3,413) -------------- -------------- $ 963 $ 874 ============== ============== NOTE D -LONG TERM INVESTMENT: In November 1999, the Company invested in a one-year, $1.0 million 10% convertible note of KSI, Inc. ("KSI"). The Company also received warrants to purchase KSI common stock in connection with this investment. All of the outstanding stock of KSI, Inc. was acquired by TruePosition, Inc., (a subsidiary of Liberty Media Corporation) in August 2000. Prior to the acquisition, the convertible note was exchanged for KSI common stock. The Company exercised warrants and purchased additional KSI common stock in 2000 aggregating a total of $758,000. The KSI common stock was exchanged for TruePosition, Inc. common stock on the date of the acquisition. 42

NOTE E - COMMITMENTS AND CONTINGENCIES: Leases: The Company leases office space under non-cancelable operating leases with expiration dates in ranging from 2001 to 2003. The Company also leases equipment and telecommunication lines and services under non-cancelable operating leases expiring through 2001. In addition, the Company leases office space, equipment and telecommunication lines and services under various rental agreements with initial terms ranging from one to twelve months. Amounts charged to operations under all lease and rental agreements totaled $0.4 million, $0.7 million and $0.9 million in 2000, 1999 and 1998, respectively. Future minimum annual lease payments at December 31, 2000, under those agreements with initial terms greater than one year are as follows (in 000's): 2001 $ 0.3 2002 0.3 2003 0.2 -------------------- $ 0.8 ==================== Employment Agreements: At December 31, 2000, the Company has one employment agreement with an employee of its Isis Tele-Communications, Inc. subsidiary that expires August 15, 2002. The agreement, which was a part of the acquisition of New England Telecom, Inc., provides for annual salary of $90,000 and contingent payouts of 50% of net profits of the former business, as defined in the agreement, with a maximum contingent total payout of $1.5 million. A total of $104,000 was accrued in contingent payouts during 2000. This amount has been capitalized as goodwill and will be amortized over four years. ISIS Management Equity Agreement: The Company incorporated its ISIS Tele-Communications, Inc. subsidiary in November 1999. In January 2000 three founder-employees of ISIS entered into a Management Equity Agreement with ISIS. This agreement provided that the founder-employees would purchase a total of 20% of the outstanding stock of ISIS, subject to restrictions as defined in the agreement. One-half of the initial shares were restricted and due to vest upon ISIS meeting certain defined financial objectives in either 2000 or 2001. At December 31, 2000 the objectives had not been met and vesting did not occur. The agreement also provided for stock appreciation rights (SARs) that allow for an additional 10% of ISIS' stock to be granted to the founder-employees based upon ISIS meeting financial objectives as defined in the agreement in either 2000 or 2001, and also allows for a cash payout option. At December 31, 2000, the SAR objectives had not been met and no accrual or expense had been recorded. NOTE F - EMPLOYEE RETIREMENT SAVINGS PLAN: The Company has adopted an Employee Retirement Savings Plan covering substantially all employees who have been employed for at least one month and meet certain age and eligibility requirements. Each eligible employee may contribute up to 15% of his or her compensation per year, subject to a maximum limit imposed by federal tax law, into various funds. Under current plan provisions, matching contributions are made by the Company equaling two-thirds of the employee's contribution, subject to a maximum of 6% of compensation contribution by the employee. Company contributions charged to costs and expenses totaled $0, $63,000 and $133,000 during 2000, 1999 and 1998, respectively. 43

NOTE G - OTHER INCOME: During 2000 the Company received a $1.5 million settlement, net of legal fees, as a result of litigation involving a supplier of its Isis Tele-Communications, Inc. subsidiary. NOTE H - INCOME TAXES: At December 31, 2000, the Company had available for federal income tax purposes net operating loss carryforwards of approximately $48.8 million and research and development tax credits of approximately $1.2 million that begin to expire in 2007. The federal income tax net operating loss carryforwards exceed the retained deficit, primarily due to the differences between financial reporting and tax treatment of certain amounts on exercise of stock options. A portion of the net operating loss carryforward (approximately $28 million) is attributed to the stock option deduction, the tax effect of which will be credited to additional paid-in capital when realized. Certain net operating loss carryforwards of the Company are subject to limitations imposed by Section 382 of the Internal Revenue Code because there was an ownership change of greater than 50% in the Company during 1991. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company's deferred tax liabilities and assets are as follows (in 000's): December 31, ----------------------------------------------- 2000 1999 1998 ------------ ------------- ------------- Deferred tax assets: Net operating loss carryforwards $ 16,584 $ 17,068 $ 17,688 Research and development credits 1,223 1,207 1,158 AMT credits 65 27 -- Reserves and allowances on financial statements in excess of tax returns 98 1,113 977 Depreciation on tax returns lower than financial statements 43 22 0 Capitalized software development costs 81 28 0 ------------ ------------- ------------- Total deferred tax assets 18,094 19,465 19,823 Deferred tax liabilities: Depreciation on tax returns lower than financial statements -- -- 90 Capitalized software development costs -- -- 125 ------------ ------------- ------------- Total deferred tax liabilities -- -- 215 ------------ ------------- ------------- Net deferred tax assets 18,094 19,465 19,608 Valuation allowance (18,094) (19,465) (19,608) ============ ============= ============= Net $ -- $ -- $ -- ============ ============= ============= The Company was placed in an Alternative Minimum Tax (AMT) position for 2000 and 1999. This has created an AMT credit of approximately $65,000 to be utilized in future tax periods against any regular federal tax liability. The Company has provided a valuation allowance of 100% of the net deferred income tax asset related to the operating loss carryforward and temporary differences. The net changes in the valuation allowance for deferred tax assets were approximately ($1.3) million, ($0.1) million and $4.0 million and were primarily attributable to the net income in 2000 and 1999 and the net operating losses incurred by the Company during 1998, respectively. 44

The reconciliation of income tax computed at the U.S. federal statutory tax rate to income tax expense is as follows (in 000's): Year Ended December 31, ----------------------------------- 2000 1999 1998 -------- -------- ---------- Income tax provision (benefit) at statutory rate of 34% $ 874 $ 894 $(3,692) Utilization of net operating loss carryforwards (874) (894) 0 (Income) losses producing no current tax benefit 0 0 3,692 Alternative minimum tax provision 38 31 0 -------- -------- ---------- Provision for income taxes, current $ 38 $ 31 $ 0 ======== ======== ========== NOTE I - STOCKHOLDERS' EQUITY: Stock Options Pursuant to the Company's 1991 Qualified Stock Option and 1991 Non-Qualified Stock Option Plans, as amended, the Company was authorized to grant options to: (i) purchase up to 280,000 shares of Common Stock to its officers and key employees, at a price not less than the fair market value per share of Common Stock on the date of grant; and (ii) purchase up to 120,000 shares of Common Stock to its directors, officers, key employees and others who rendered services to the Company at such price as fixed by the Compensation and Stock Option Committee, respectively. Options granted under both the 1991 Qualified Plan and 1991 Non-Qualified Plan generally vest to the respective option holders at the rate of 20% per year commencing on the first anniversary date of the grant. No new grants may be made under the 1991 Plans. The Company's 1993 Non-Employee Director Stock Option Plan allows the Company to grant options to purchase up to 70,000 shares of Common Stock. Each non-employee director is to be granted options to purchase: (i) 2,000 shares of Common Stock upon initial appointment as a director of the Company; and (ii) an additional 1,200 shares, in recurring annual increments, at a price equal to the fair market value per share of Common Stock on the date of grant. Options under the Non-Employee Director Plan vest to the respective option holder after one year and have a term of ten years. The Company's 1996 Stock Option Plan authorizes the grant of both incentive ("ISO") and non-qualified stock options up to a maximum of 335,000 shares of the Company's Common Stock to employees (including officers and directors who are employees) of and consultants to the Company. The exercise price, term and vesting provision of each option grant is fixed by the Compensation and Stock Option Committee with the provision that the exercise price of an ISO may not be less than the fair market value of the Company's Common Stock on the date of grant, and the term of an ISO may not exceed ten years. The Company has chosen to measure stock-based compensation cost under the intrinsic-value method of Accounting Principles Board Opinion No. 25 (APB 25) and related interpretations. Under APB 25, if the exercise price of the Company's employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized. Pro forma information regarding net income (loss) and earnings (loss) per share is required by Statement 123 and has been determined as if the Company had accounted for its employee stock options under the fair value method of that Statement. In that regard, the fair value for options granted during 2000, 1999 and 1999 was estimated at the date of grant using a Black-Scholes option-pricing model with the following weighted-average assumptions for 2000, 1999 and 1998: 45

NOTE K- ACQUISITION OF NEW ENGLAND TELECOM, INC. On August 10, 2000, the Company announced the acquisition of substantially all of the assets of New England Telecom, Inc. ("NET") through Isis Tele-Communications, Inc. ("Isis") the Company's majority-owned subsidiary. The agreement included the purchase of approximately $135,000 in inventory of prepaid phone cards, an employment agreement with the principal NET shareholder and a two-year earn-out period. The earn-out is calculated on a quarterly basis whereby the former shareholder can earn up to 50% of net profits of the former business, as defined in the agreement, with a maximum contingent total payout of $1.5 million. The transaction is being accounted for using the purchase method of accounting, and, accordingly, the results of NET's operations 47

have been included in the Company's consolidated financial statements from the date of acquisition. The cash purchase price represented the value of the inventory assets purchased. Any future purchase price payments made contingent upon net profit during the earn-out period, as defined in the agreement, will be capitalized as goodwill and amortized over four years. The former shareholder through December 31, 2000 earned a total of $104,000 of the $1.5 million maximum amount. Should Isis terminate the employee without cause, as defined in the agreement, or should ISIS cease to sell pre-paid phonecards prior to the end of the two-year earn-out period, ISIS will be liable for any unpaid contingent compensation up to a total of $1.5 million. The agreement also provides for 20,000 stock options of its ISIS subsidiary to be granted to the employee over a three-year period, as defined in the agreement. At December 31, 2000, there were 1,620,000 shares of ISIS common stock outstanding, and 200,000 shares authorized for issuance in its stock option plan. There were no liabilities assumed in the transaction. If the Company's results had been combined with the results of NET, revenue and net income would have been as follows: In 000's Year ended December 31, 1999 Revenue Net Income - ---------------------------- ------- ---------- CTS, as previously reported $10,241 $ 2,599 NET, unaudited 18,329 19 ------- ------- Pro-Forma Combined $28,570 $ 2,618 Earnings per pro-forma share: Basic $ 1.15 Diluted $ 1.14 Year ended December 31, 2000 CTS, as reported $25,973 $ 2,552 NET, unaudited 12,176 364 ------- ------- Pro-Forma Combined $38,149 $ 2,916 Earnings per pro-forma share: Basic $ 1.28 Diluted $ 1.25 NOTE L - SETTLEMENT OF LITIGATION AND ACQUISITION OF COMMUNICATIONS INFORMATION SERVICES, INC. On July 28, 2000, the Company announced the settlement of a patent infringement lawsuit originally brought in 1998 by Communications Information Services, Inc. ("CISI") against the Company and AirTouch Communications, Inc. ("AirTouch"). The settlement, in which no liability or fault was admitted by the Company or AirTouch, provided for the Company's acquisition of all of the capital stock of CISI, including certain patent license rights for a one-time cash payment of $500,000. There were no other assets or liabilities of CISI. The transaction was accounted for using the purchase method. The accounting for the purchase was finalized during the fourth quarter of 2000 with the payment of $500,000 being offset against a previously established accrual for the use of the technology. No pro-forma information is presented for 1999 or 2000, as CISI had no sales or net income during those periods. NOTE M- SEGMENT INFORMATION The Company has two reportable business segments the year ended December 31, 2000 which offer distinctive products and services marketed through different channels: (i) the Company's Blackbird'r' Platform product line, which includes the Blackbird'r' Platform, PreTect'TM' cloning-fraud prevention application, No Clone Zone'sm' roaming-fraud prevention service, and related application products and services; and (ii) the Company's prepaid long-distance phone card business, which is conducted through its majority-owned subsidiary, Isis Tele- 48

Communications, Inc. Management evaluates segment performance based upon segment profit or loss before income taxes. The difference in the pretax segment income of $2,610,000 and net income of $2,552,000 for the year ended December 31, 2000 is attributable to income tax expense of $58,000. There were no inter-company sales of products between the segments. The Company's phone card business segment was not in operation in 1998, and had sales of $19,000 in 1999.

WITNESSETH: Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord the premises described in paragraph 1(b) below for the term and subject to the terms, covenants, agreements and conditions hereinafter set forth, to each and all of which Landlord and Tenant hereby mutually agree. 1. Definitions. Unless the context otherwise specifies or requires, the following terms shall have the meanings herein specified: (a) The term "Building" shall mean the parcel of real property described on Exhibit A attached hereto, situated in the location and commonly know by the name specified in the Basic Lease Information, which name Landlord may change at any time, and all other improvements on or appurtenances to such parcel. (b) The term "premises" or "premises" shall mean that portion of a floor of the Building outlined in red on the diagrams attached hereto as Exhibit B. The premises contain the net rentable area specified in the Basic Lease Information. 2. Additional Rental for Operating Expenses. This is a "triple-net" lease. In addition to the Basic Rental provided in the Basic Lease Information above and Section 5 below, Tenant agrees to pay Landlord "Additional Rental" for Operating Expenses during each Lease Year based upon Tenant's percentage share of the total dollar amount of Operating Expenses incurred by Landlord in each Lease Year related to the Premises and the Building. Tenant's percentage share of such Operating Expenses shall be the ratio that the floor area of the Premises (10,471 net rentable square feet) bears to the total rentable square footage of the Building (115,069 net rentable square feet) (9.10%). The Operating Expenses are currently applied as listed on Exhibit E. The percentage share of Operating Expenses shall be adjusted when the final rentable square footage of the Premises and the Building is determined, and Landlord shall deliver written notice to Tenant a statement upon commencement of the Lease Term confirming such amounts if different than those stated herein. Landlord reserves the right to modify and adjust Tenant's percentage share of the Building and/or the Premises in the event the Premises or the Building shall be changed in size or remeasured which results in a change of 1% or greater of that stated herein. Such written notice shall be delivered to Tenant on or before January 15th of the ensuing calendar year. Such modification or adjustment shall apply beginning as of January 15th of the ensuing calendar year and shall not be applied retroactively. The term "Operating Expenses" means all costs of ownership, management, operation, and maintenance of the Building, including, without limitation, the following: wages and salaries of employees; janitorial, cleaning, landscaping, irrigation, storm water, guard and other services; gas, electricity, water, sewer, waste disposal, and other utilities; heating, ventilation and air-conditioning; window-washing; materials and supplies; painting, repairs, and other maintenance; parking lot resurfacing and restriping; maintenance, repair, replacement, service of equipment and service agreements of any kind, elevator equipment, and other equipment; reserves for any common area improvements; costs of independent contractors; management fees; insurance of any kind; Condominium and/or Building association fees, taxes, assessments and other governmental and utility charges of any kind; the cost of any repair, renovation, alteration, and improvement required to be made by Landlord under any governmental law, rule or regulation; and any other expense or charge which in accordance with generally accepted accounting and management principles which are consistently applied would be considered a cost of ownership, management, operation, and maintenance of the Building. Restrictions to Operating Expenses are as follows: Wages and salaries of employees are limited to a level at or below the property manager; Gas, electricity, water, sewer, and other utilities should be limited to those supplied to common areas only (and not other tenants which may be billed separately); Management fees should be limited to a maximum of 5%; and the costs of repairs, renovations, alteration and improvements "required to be made by Landlord under any governmental law" are limited to laws enacted after the date of this Lease. Subject to the arbitration procedure for disputes set forth in subparagraph 41, the determination of Operating Expenses and their allocation to all the tenants of the Building shall be made by Landlord in its sole and absolute discretion. Notwithstanding other statements contained herein to the contrary, Tenant is responsible for the entire cost of maintenance, repairs, replacements of HVAC systems, alarm systems and other electrical items related to its Premises, provided that such cost items are not prorated to other tenants of the Building. Payment of these direct cost items shall be made by Tenant immediately as such cost items are incurred. Landlord warrants that the HVAC system, fire alarm system and other electrical items related to the Premises are in proper working order at the commencement of this Lease. Prior to commencement of each Lease Year, or as soon thereafter as practicable, Landlord shall give Tenant notice of its estimate of amounts payable under this section for the ensuing Lease Year. On the first day of each month during the ensuing Lease Year, Tenant shall pay to Landlord 1/12th of such 4

estimated amounts, provided, that if such notice is not given prior to the commencement of such ensuing Lease Year, Tenant shall continue to pay on the basis of the prior Lease Year's estimate until the month after such notice is given. If at any time or times it appears to Landlord that the amounts payable under this section for the current Lease Year will vary from its estimate, Landlord may, by notice to Tenant, revise its estimate for such Lease Year, and subsequent payments by Tenant for such Lease Year shall be based upon such revised estimate. Within ninety (90) days after the close of each Lease Year or as soon after such 90-day period as practicable, Landlord shall deliver to Tenant a statement of amounts payable under this section for such Lease Year and such statement shall be final and binding upon Landlord and Tenant. If such statement shows an amount owing by Tenant that is less than the estimated payments for such Lease Year previously made by Tenant, it shall be accompanied by a refund of the excess. If such statement shows an amount owing by Tenant that is more than the estimated payments for such Lease Year previously made by Tenant, Tenant shall pay the deficiency to Landlord within thirty (30) days after delivery of the statement. Tenant shall be entitled at its expense to review at Landlord's offices the records on which the statement of amounts payable is based. In determining the amount of Operating Expenses, for the purpose of this Section 6: (a) if less than one hundred percent (100%) of the Building shall have been occupied by tenants and fully used by them at any time, Operating Expenses shall be increased to an amount equal to the like operating expenses which would normally be expected to be incurred had such occupancy been ninety-five percent (95%) and had such full utilization by tenants been made during the entire period; and (b) if the Landlord is not furnishing any particular work or service (the cost of which if performed by the Landlord would constitute an Operating Expense) to a tenant who has undertaken to perform such work or service in lieu of the performance thereof by the Landlord, Operating Expenses shall be deemed for the purposes of this Section 2 to be increased by an amount equal to the additional Operating Expense which would reasonably have been incurred during such period by the Landlord if it had at its own expense furnished such work or service to such tenant. Tenant shall pay as rent monthly, in addition to the Basic Rental and Additional Rental during the term of this Lease such "Special Building Operating Expenses" as are required and incurred as a result of Tenant's occupancy and use of the Premises, or any part thereof, and which are in addition to normal business office expenses, which Special Building Operating Expenses shall include but not be limited to unusual utility costs; unusual heat, air conditioning or water requirements; increase in insurance premiums attributable to the Tenant's business and/or use or occupancy of the Premises; and the like. "Lease Year" shall mean calendar year. If this Lease commences or terminates on a day other than the first or last day of a calendar year, the amount of additional rental payable by Tenant applicable to the Lease Year in which such commencement or termination occurs shall be prorated on the basis of a 365-day year. 3. Premises. (a) Tenant hereby acknowledges that, except as set forth herein, the premises shall be delivered in an "as is" condition and that Landlord, except as may be expressly agreed by Landlord in writing as specified herein and in Exhibit D attached hereto, has no obligation to alter, repair, renovate, or render fit for Tenant's occupancy, any part of the premises. Landlord reserves to itself the use of the roof, exterior walls and the area above and beneath the premises, together with the right to install, maintain, use, repair and replace plumbing, telephone facilities, equipment, machinery, connections, pipes, ducts, conduits, and wires leading through the premises and serving other parts of the Building in a manner and in locations which will not unreasonably interfere with Tenant's use. (b) In the event Landlord determines to permit early occupancy of the premises and, therefore, informs Tenant in writing that the premises are ready for occupancy prior to the date set forth in the Basic Lease Information for the commencement of the term of the Lease, Tenant shall have the right to take early occupancy of the premises on such date as Landlord and Tenant shall agree, and notwithstanding the provisions of paragraph 4 below, the term of the Lease shall commence upon such occupancy. (c) The occupancy by Tenant of the premises shall constitute an acknowledgment by Tenant that the premises are then in good, sanitary and tenantable condition and repair. Notwithstanding the foregoing, Landlord represents and warrants, to the best of its knowledge without inquiry, to Tenant that, as of the Commencement Date, the Premises, including any improvements made by Landlord, shall be incompliance with all laws and regulations, and built in a good and workmanlike manner with good materials and the equipment and Building services serving the Premises shall be in good working order. 4. Term. The initial term of this Lease shall commence and, unless renewed or sooner terminated in accordance with this Lease, shall end on the date respectively specified in the Basic Lease Information. If Landlord for any reason cannot deliver possession of the premises to Tenant, in condition reasonably 5

satisfactory to Tenant and in accordance with the space plan attached hereto as Exhibit B, by the date specified for term commencement, this Lease shall not be void or voidable in that event, provided that the delay is not occasioned by the act or omission of Tenant, rental shall be waived for the period between the commencement of such term and the date when possession is delivered substantially complete. Provided, however, if Landlord has not delivered the premises to Tenant substantially completed within sixty (60) days of the Term Commencement, then Tenant shall have the right to terminate this Lease upon written notice to Landlord, without liability to either party, so long as such failure is not due to a delay caused by the act of omission of Tenant. 5. Rent. Tenant shall pay to Landlord as rental for the use and occupancy of the premises, at the times and in the manner hereinafter provided, the following sums of money: (a) Tenant shall pay to Landlord basic rent in the amount specified in the Basic Lease Information per year, payable in equal monthly installments in advance on the commencement of the term hereof and on or before the first day of each and every successive calendar month during the term hereof. If the term commences on other than the first day of a calendar month, the first payment of rent shall be appropriately prorated on the basis of a 30-day month. (b) Tenant shall pay, as additional rent, all sums of money required to be paid to Landlord as stated above and all other sums of money or charges required to be paid by Tenant hereunder in addition to basic rent, whether or not the same are designated "additional rent". If such amounts or charges are not paid at the time provided in this Lease, they shall nevertheless be collectible as additional rent with the next installment of minimum rental thereafter falling due, but nothing herein contained shall be deemed to suspend or delay the payment of any amount of money or charge at the time the same becomes due and payable hereunder, or limit any other remedy of Landlord. All amounts of money payable by Tenant to Landlord under this Lease, if not paid when due, shall bear interest from the due date until paid at the rate of the greater of 15% per annum or the prime rate publicly announced by the Bank of America at (Seattle Washington office) or its successor or its equivalent size competitor in the Seattle market place should Bank of America cease to exist, but not to exceed the maximum rate of interest permitted by law ("Default Interest"). All payments due from Tenant to Landlord hereunder shall be made to Landlord without deduction or offset in lawful money of the United States of America at Landlord's address for notices hereunder, or to such other person at such other place as Landlord may from time to time designate in writing to Tenant. (c) Tenant hereby acknowledges that late payment by Tenant to Landlord of rent and other sums due hereunder after the expiration of any applicable grace period will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult to ascertain. Such costs include, but are not limited to, processing and accounting charges, and late charges which may be imposed on Landlord by the terms of any mortgage or trust deed covering the premises. Accordingly, if any installment of rent or any other sums due from Tenant shall not be received by Landlord within 10 days after the due date, Tenant shall pay to Landlord a late charge equal to 6% of such overdue amount. The parties hereby agree that such late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant. Acceptance of such late charge by Landlord shall in no event constitute a waiver of Tenant's default as provided above, or prevent Landlord from exercising any of the other rights and remedies available to Landlord hereunder or at law. 6. Taxes and Assessments. In addition to the monthly rental and other charges to be paid by Tenant hereunder, Tenant shall reimburse Landlord upon demand for any and all taxes, assessments, condominium and/or Building associations fees, levies, fees, charges and impositions whatsoever levied or imposed or assessed by any authority having the direct or indirect power to tax, including, without limitation, any city, county, state or federal government or any improvement or other assessment district, whether or not consented to or joined in by Landlord, payable by Landlord (other than income taxes, measured by the net income of Landlord from all sources), whether or not now customary or within the contemplation of the parties hereto on the date of this Lease: (a) upon, measured by or reasonably attributable to the cost or value of Tenant's equipment, furniture, fixtures and other personal property located in the premises or by the cost or value of any leasehold improvements made in or to the premises by or for Tenant, other then building standard tenant improvements made by Landlord, regardless of whether title to such improvements shall be in Tenant or Landlord; (b) upon or measured by the rental payable hereunder, including without limitation any gross income tax or excise tax levied by any city, county, state, federal or other governmental body with respect to the receipt of such rental; (c) upon or with respect to the possession, leasing, operation, management, maintenance, improvement, alteration, repair, use or occupancy by Tenant of the premises or any portion thereof; (d) upon this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the premises. In the event that it shall not be lawful for Tenant so to reimburse Landlord, the monthly rental payable to Landlord under this Lease shall be revised to net Landlord the same net rental after such imposition as would have been payable to Landlord prior to such imposition. 6

7. Operation Expenses-Utilities and Other Services by Landlord. Landlord agrees that there will bea available at the Premises the following utilities and services: Electricity ( a minimum power available to the Premises of 200 amps/220-240 and 110-120 volts for the duration of the Lease), hot and cold water suitable for drinking, restroom and office janitorial/cleaning service, , gas, and the other utilities and services described in the definition of Operating Expenses described in this Lease. All such utilities and services shall be paid for by Tenant as Additional Rental for Operating Expenses pursuant to Section 2. Landlord does not warrant the adequacy of such utilities for Tenant's needs or that any of the foregoing utilities and services will be free from interruption due to causes outside of the reasonable control of Landlord. Interruption of utilities or services shall not be deemed an eviction or excuse performance of any of Tenant's obligations under this Lease or render Landlord liable for damages (except if due to causes within the reasonable control of Landlord). If separate metering is necessary due to Tenant's excessive use thereof, Tenant shall be charged the installation cost of such meters. Other than the utilities and services required to be provided by Landlord in this Lease, Tenant shall, at Tenant's expense, provide all other utilities and other services to the Premises required by Tenant, and shall pay for the same when due. Tenant has had the opportunity to have an electrician determine that there is adequate power to the building for Tenant's use in the Premises. 8. Maintenance by Landlord. Landlord shall maintain in good condition (normal wear and tear excepted) the structural and exterior components of the Building. Landlord, with cost shared on a pro rata basis to all tenants of the Building, shall repair and replace, when necessary, light fixtures (including replacement of light bulbs and fluorescent tubes) and shall maintain in good condition and repair the underground plumbing and the electrical system in the Building. However, Landlord shall not be obligated to repair or replace any fixtures or equipment installed by Tenant and Landlord shall not be obligated to make any repair or replacement occasioned by any act or omission of Tenant, its employees, agents, invitees, or licensees. Landlord is responsible for all repairs, cleaning and maintenance to electrical, lighting, lightbulbs, and plumbing from the inside of exterior wall, or middle of the demising wall, as the case may be, to the opposite inside of the exterior wall, or middle of the demising wall of the Premises. Tenant is responsible to pay for any and all such cost on a pro-rata basis as defined in section 2. Tenant's installed personal equipment is not considered part of the real property to the extent it is attached to the Premises as long as Tenant removes such personal property prior to the expiration of this Lease and repairs the Premises to a similar condition which the Premises were in prior to any such equipment being attached thereto. 9. Alterations, Repairs, and Maintenance by Tenant. Tenant shall make no changes, improvements, or alterations to the Premises without the prior consent of Landlord. Except as stipulated in Section 14 below, all such changes, improvements, and alterations and repairs, if any, made by Tenant shall remain on the Premises and shall become the property of Landlord upon the expiration or sooner termination of this Lease. Tenant shall keep the Premises in a neat, clean, and sanitary condition, and shall keep the Premises and all items therein installed by Tenant in good condition, except only for reasonable wear and tear. Tenant may install operating equipment of legal intent within the Premises such as additional electrical service, plumbing fixtures, roof vents, gas lines, telephones and computer network cabling as are customary to its business and in compliance with all City of Seattle codes, ordinances and zoning. 10. Estimated Payments. Unless otherwise expressly designated herein, all monetary amounts payable to Landlord pursuant to this Lease shall be payable as follows:(a) During December of each Lease Year or as soon thereafter as practicable, Landlord shall give Tenant notice of its estimate of amounts payable hereunder for the ensuing Lease Year. On or before the first day of each month during the ensuing Lease Year, Tenant shall pay to Landlord 1/12 of such estimated amounts, provided that if such notice is not given in December Tenant shall continue to pay on the basis of the prior year's estimate until the month after such notice is given. If, at any time or times, it appears to Landlord that the amounts payable for the current Lease Year will vary from its estimate by more than 5%, Landlord shall, by notice to Tenant, revise its estimate for such year, in which case subsequent payments by Tenant for such year shall be based upon such revised estimate. (b) Within 90 day after the close of each Lease Year or as soon after such 90-day period as practicable, Landlord shall deliver to Tenant a statement of amounts payable for such Lease Year. If on the basis of such statement Tenant owes an amount that is less than the estimated payments for such Lease Year previously made by Tenant and Tenant is not in default hereunder, Tenant shall receive a credit in the amount if such excess against the installments due under Section 2 hereof prorated over the balance of the remaining calendar year. If on the basis of such statement Tenant owes an amount that is 7

more than the estimated payments for such Lease Year previously made by Tenant, Tenant shall pay the deficiency to Landlord within 30 days after delivery of the statement. (c) If this Lease shall terminate on other than the last day of a calendar year, the adjustment in rent applicable to the Lease Year in which such termination shall occur shall be prorated on the basis which the number of days from the commencement of such Lease Year to and including such expiration date bears to 365. If the adjustment in rent is not determined until after the termination of this Lease, any excess amounts due Tenant or deficiency amounts due Landlord shall be paid in cash within 30 days after delivery of the statement setting forth such adjustment determination. (d) Notwithstanding the foregoing, if, at any time, Landlord incurs for any item actual costs or expenses which are reimbursable in whole or in part by Tenant pursuant to this Lease and such costs or expenses are in excess of the estimated amount budgeted for such item and otherwise payable by Tenant, then, upon written demand from Landlord accompanied by a statement of such costs of expenses, Tenant shall immediately pay to Landlord the full amount of any excess reimbursable costs or expenses within 30 days of being billed. 11. Common Areas. (a) The use and occupation by Tenant of the Premises shall include a right to the use in common with others entitled thereto of the common areas and other facilities as may be designated from time to time by Landlord, subject, however, to the terms and conditions of this Lease. All common areas and facilities not within the Premises, which Tenant may be permitted to use and occupy pursuant to this paragraph, are to be used and occupied under a revocable license. If the measure of such areas is diminished by Landlord, Landlord shall not be subject to any liability nor shall Tenant be entitled to any compensation or diminution or abatement of rent, nor shall such diminution of such areas be deemed constructive or actual eviction. (b) Landlord shall at all times during the term of this Lease have the following rights with respect to the common area and other facilities: (1) Landlord shall have the right from time to time to alter and modify the common areas and other facilities as it deems desirable in its sole discretion; (2) Landlord may discontinue the existence of the common area subject to the requirements of laws and ordinances applicable thereto; (3) Landlord may uniformly promulgate and enforce such rules and regulations relating to the use of the common areas and other facilities as Landlord deems necessary or desirable. Landlord shall exercise the foregoing rights in such a manner as to minimize the interference with Tenant's beneficial enjoyment of the premises. (c) Notwithstanding anything to the contrary, during the term of this Lease, Landlord shall at all times operate and maintain the restrooms adjacent to the Premises (as depicted in the attached Exhibit B) and Tenant shall have continuous right of access and use of such restrooms. Landlord represents, warrants and covenants that such restrooms, including any improvements made by Landlord, shall be in compliance with all laws and regulations, and built in a good and workmanlike manner with good materials, and the equipment and Landlord services serving such restrooms shall be in good working order. 12. Use. (a) The premises shall be used solely for general office purposes and no other, except services that are permitted under codes for the City of Seattle. Tenant shall not use or permit the premises to be used for any other purpose without Landlord's prior written consent. Landlord and Tenant hereby further acknowledge that the identity of Tenant, the specific character of Tenant's business and anticipated use of the premises and the relationship between such use and other uses within the Building has been a material consideration to Landlord's entry into this Lease. Any material change in the character if Tenant's business or its financial condition or use shall constitute a default under this Lease. (b) Tenant shall not do or permit to be done in, on or about he premises, nor bring or keep or permit to be brought or kept therein, anything which is prohibited by or will in any way conflict with any law, statute, ordinance or governmental rule or regulation now in force or which may hereafter be enacted or promulgated, or which is prohibited by the standard form of fire insurance policy or will in any way increase the existing rate of or affect any fire or other insurance upon the Building, or cause a cancellation of any insurance policy covering the Building or any part thereof of any of its contents. Tenant shall not do or permit anything to be done in or about the premises which will in any way obstruct or interfere with the rights of other tenants of the Building, or injure or annoy them, or use or allow the premises to be used for any improper, immoral, unlawful or objectionable purpose. Nor shall Tenant cause, maintain or permit any nuisance in, or about the premises or commit or suffer to be committed any waste in or upon the premises. 8

c) Except for normal office and janitorial supplies in customary quantities, Tenant shall not cause or permit any Hazardous Material to be brought upon, kept or used in or about the premises or the Building. If Tenant breaches the obligations stated in the preceding sentence, or if the presence of Hazardous Material on the premises or the Building caused or permitted by Tenant results in contamination of the premises or the Building the Tenant shall indemnify, defend and hold Landlord harmless for, from and against any and all claims, judgments, damages, penalties, fines, costs, liabilities or losses (including, without limitation, diminution in value of the Building, damages for the loss or restriction on use of rentable or usable space or of any amenity of the Building, damages arising from any adverse impact on marketing of space in the Building, and sums paid in settlement of claims, reasonable attorneys' fees, consultant fees and expert fees) which arise during or after the Lease Term as a result of such contamination. This indemnification of Landlord by Tenant includes, without limitation, costs incurred in connection with any investigation of site conditions or any cleanup, remedial, removal or restoration work required by any federal, state or local governmental agency or political subdivision because of hazardous Material present in or about any part of the Building, including, without limitation, the soil or ground water under the Building. As use herein, the term "Hazardous Material" means any hazardous or toxic substance, material or waste which is or becomes regulated by any federal, state or other local governmental authority, including, without limitation, any material or substance which is designated as a "hazardous substance" pursuant to Section 311 of the Federal Water Pollution Control Act (33 U.S.C. '1317), defined as a "hazardous waste@ pursuant to Section 1004 of the Federal Resource Conservation and Recovery Act, (42 U.S.C. 6901 et seq.), or defined as a "hazardous substance" pursuant to Section 101 of the Comprehensive Environmental Response, Compensation and Liability Act (42 U.S.C. ' 9601 et seq.). 13. Liens. Tenant shall keep the premises and the Building free from any liens arising out of any work performed, materials furnished or obligations incurred by Tenant. In the event that Tenant shall not, within 10 days following the imposition of any such lien, cause the same to be released of record, Landlord shall have, in addition to all other remedies provided herein and by law, the right but not the obligation to cause the same to be released by such means as it shall deem proper, including payment of the claim giving rise to such lien. All sums paid by Landlord for such purpose, and all expenses incurred by it in connection therewith including, without limitation, any attorneys fees, court costs, and expenses of litigation, together with Default interest thereon, shall be payable to Landlord by Tenant on demand. Nothing in this Lease shall be construed in any way as constituting the consent or request of the Landlord, expressed or imposed, by inference or otherwise, to any contractor, subcontractor, laborer, or materialmen, for the performance of any labor, or the furnishing of any materials for any specific improvement, alteration and repair of or to the premises or as giving Tenant the right, power or authority, to contract for or permit the rendering of any service or the furnishing of any material that would give rise to the filing of any mechanic's liens against the Premises. Landlord shall have the right to post and keep posted on the premises any notices, that may be provided by law or which Landlord may deem to be proper for the protection of Landlord, the Premises and the Building from such liens, and Tenant shall give Landlord at least 5 days' prior notice of the date of commencement of any construction on the Premises in order to permit the posting of such notices. 14. Damage and Destruction. (a) If the premises or the portion of the Building necessary for Tenant's occupancy should be damaged or destroyed during the term hereof by any casualty insurable under standard fire and extended coverage insurance policies, Landlord shall (except as hereafter provided) repair or rebuild the premises to substantially the condition in which the premises were immediately prior to such destruction. (b) Landlord's obligation under this paragraph shall in no event exceed the lesser of (1) with respect to the premises, the scope of building standard improvements installed by Landlord in the original construction of the premises, or (2) the extent of proceeds received by Landlord or any insurance policy maintained by Landlord pursuant to paragraph 17(a) below, unless Landlord nevertheless elects to repair or rebuild the premises. (c) The minimum rent shall be abated proportionately during any period in which, by reason of any damage or destruction not occasioned by the negligence or willful misconduct of Tenant or Tenant's employees or invitees, there is a substantial interference with the operation of the business of Tenant. Such abatement shall be proportional to the measure of business in the Premises which Tenant may be required to discontinue. The abatement shall continue for the period commencing with such destruction or damage and ending with the completion by the Landlord of such work, repair or reconstruction as Landlord is obligated to do. (d) Notwithstanding the foregoing, if the premises, or the portion of the Building necessary for Tenant's occupancy should be damaged or destroyed (1) to the extent of 10% or more of the then replacement value of either, (2) in the last year of the term hereof, (3) by a cause or casualty other than those covered by fire and extended coverage insurance, or (4) to the extent that it would take, in Landlord's opinion, in excess of 180 days to complete the requisite repairs, then Landlord or Tenant may either terminate this Lease or elect to repair or restore said damage or destruction, in which event 9

Landlord shall repair or rebuild the same as provided in subparagraph (a) above. If such damage or destruction occurs and this Lease is not so terminated by Landlord, this Lease shall remain in full force and effect. The parties hereby waive the provisions of any law that would dictate automatic termination or grant either party an option to terminate in the event of damage or destruction. Landlord's election to terminate Landlord's obligation under this paragraph shall be exercised by written notice to Tenant given within 60 days following the damage or destruction. Such notice shall set forth the effective date of the termination of this Lease. (e) Upon the completion of any such work of repair or restoration by Landlord, Tenant shall forthwith repair and restore all other parts of the premises including without limitation, non-building standard leasehold improvements and all trade fixtures, equipment, furnishings, signs and other improvements originally installed by Tenant, subject to the requirements of subparagraph 12(a) above. 15. Indemnification. Except to the extent caused by the negligence or willful misconduct of Landlord or Landlord's agents, employees or invitees, Landlord shall not be liable to Tenant and Tenant hereby waives all claims against Landlord for any injury to or death of any person of damage to or destruction of property in or about the premises or the Building by or from any cause whatsoever, including, without limitation, acts of other tenants or other third parties, gas, fire, oil, electricity or leakage of any character from the roof, walls, basement or other portion of the premises or the Building. Except to the extent caused by the negligence or willful misconduct of Landlord or Landlord's agents, employees or invitees, Tenant shall hold Landlord and any ground Landlord harmless for, from and against and defend Landlord against any and all claims, liability, damage or loss, and for, from and against all costs and expenses, including reasonable attorneys' fees, arising out of any injury to or death of any person or damage to or destruction of any property, from any cause whatsoever (except any cause resulting solely from the negligence or willful act of Landlord, its authorized agents or employees) to the extent: (i) occurring in or about the Premises , or (ii) occurring on or about any portion of the common areas or elsewhere in or about the Building, but only to the extent that such injury or damage shall be caused in whole or in part by the act, neglect, default or omission of any duty by Tenant, its agents, employees or invitees or otherwise by any conduct or transactions of any of said persons in or about or concerning the premises, including any failure of Tenant to observe or perform any of its obligations hereunder. The provisions of this paragraph 15 shall survive the termination of this Lease with respect to any damage, injury or death occurring prior to such termination for a maximum of one year. 16. Insurance. (a) Tenant shall procure and maintain in full force and effect during the entire term hereof, at its own expense and in companies acceptable to Landlord, the following policy or policies of insurance. (1) Comprehensive liability insurance, including property damage, insuring Landlord and the Building, as Landlord may designate, hereinafter called additional designated insured from and against all claims, demands, actions or liability for injury to or death of any persons, and for damage to property arising from or related to the use of occupancy of the premises or the operation of Tenant's business. No deductible shall be carried under this coverage without the prior written consent of Landlord. Such policy shall contain but not be limited to, coverage for premises and operations, products and completed operations, blanket contractual, personal injury, operations, ownership, maintenance and use of owned, non-owned, or hired automobiles, bodily injury and property damage. The policy shall have limits in amounts not less than $1,000,000 per person and per occurrence, with an aggregate limit of $2,000,000. This insurance shall carry a contractual coverage endorsement specifically insuring the performance by Tenant of its indemnity agreement contained in paragraph 15 above. If in the opinion of Landlord's insurance advisor, acting reasonably based on a substantial increase in recovered liability claims, the aforesaid amounts of coverage are no longer adequate, then such coverage shall be proportionately increased. (2) Worker's Compensation Insurance and Employer's Liability Insurance with a limit of no less than that amount required by law, provided that Employer's Liability Insurance shall have a minimum coverage of $1,000,000 per person and per occurrence. (3) Fire insurance with standard extended coverage of all risk endorsement, including, without limitation, vandalism and malicious mischief, to extent of 90% of the replacement value of all furnishings, trade fixtures, leasehold improvements, equipment, merchandise and other personal property and leasehold improvements from time to time situated in, on or upon the premises. As long as this Lease is in effect, the proceeds from any such insurance shall be held in trust to be used only for the repair or replacement of the improvements, fixtures and other property so insured. (b) Landlord may elect to procure and maintain liability insurance and insurance covering fire and such other risks of direct indirect loss or damage as it reasonably deems appropriate, including extended and broad form coverage risks, mudslide, land subsidence, volcanic eruption, flood and earthquake, on leasehold as improvements in the Building. Tenant shall reimburse Landlord for the costs of all such insurance as part of Operating Expenses reimbursable pursuant to paragraph 2. Any insurance coverage herein provided shall be for the benefit of Landlord, Tenant and any additional designated insured, as their 10

interests may appear, Tenant shall not adjust losses or execute proofs of loss under such policies without Landlord's prior written approval. (c) Should this Lease be canceled pursuant to the provisions of paragraph 14 above by reason of damage or destruction and Tenant is thus relieved of its obligation to restore or rebuild the improvements on the premises, any insurance proceeds for damage to the premises, including all fixtures and leasehold except Tenant's furnishings, equipment and trade fixtures, improvements thereon, shall belong to Landlord, free and clear of any claims by Tenant. (d) All policies of insurance described in this paragraph 16 of which Tenant is to procure and maintain, shall be issued by good, responsible companies, reasonably acceptable to Landlord and qualified to do business in the state in which the Building is situated. Executed copies of such policies of insurance or, at Landlord's election, certificates thereof, shall be delivered to Landlord and any additional designated insureds within 10 days after delivery of possession of the premises to Tenant and thereafter within 30 days prior to the termination or expiration of the term of each existing policy. All public liability and property damage policies shall contain the following provisions: (1) Landlord, and any additional designated insureds although named as insured, shall nevertheless be entitled to recovery under said policies for any loss occasioned to them, their servants, agents and employees by reason of the negligence of Tenant, its officers, agents or employees; (2) the company writing such policy shall agree to give Landlord and any additional designated insured not less than 30 days notice in writing prior to any cancellation, reduction or modification of such insurance; and (3) at the election of Landlord's mortgagee, the proceeds of any insurance shall be paid to a trustee or depository designated by Landlord's mortgagee. All public liability, property damage and other casualty policies shall be written as primary policies, not entitled to contribution from, nor contributing with, any coverage which Landlord may carry. Tenant hereby acknowledges that the late delivery by Tenant to Landlord of the insurance certificates or policies referred to above will cause Landlord to incur costs not contemplated by this lease, the exact amount of which will be extremely difficult to ascertain. Such costs include, but are not limited to, processing and accounting charges and penalties which may be imposed on Landlord by the terms of any mortgage or trust deed covering the premises. Accordingly, if any insurance certificate or policy required to be delivered by Tenant above shall not be received by Landlord at the time prescribed above, Tenant shall pay to Landlord a charge in the sum of $300. The parties hereby agree that such charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late delivery by Tenant, and acceptance of such charge by Landlord shall in no event constitute a waiver of Tenant's default with respect to such late delivery, nor prevent Landlord from exercising any of the other rights and remedies available to Landlord hereunder or at law. (e) Notwithstanding anything to the contrary contained within this paragraph, Tenant's obligations to carry the insurance provided for herein may be brought within the coverage of the so-called blanket policy or policies of insurance carried and maintained by Tenant; provided, however, that (1) Landlord and such other persons shall be named as additional insureds thereunder as their interests may appear; (2) the coverage afforded to Landlord and such other persons will not be reduced of diminished by reason of the use of such blanket policy of insurance; and (3) all other requirements set forth herein are otherwise satisfied. (f) If Tenant should fail either to acquire the insurance required pursuant to this paragraph 16 and to pay the premiums therefor or to deliver required certificates or policies, Landlord may in addition to any other rights and remedies available to Landlord, acquire such insurance and pay the requisite premiums therefor, which premiums shall be payable by Tenant to Landlord immediately upon demand. (g) Landlord and Tenant hereby waive any rights each may have against the other for loss or damage to its property or property in which it may have an interest where such loss is caused by a peril of the type generally covered by fire insurance with extended coverage or arising from any cause which the claiming party was obligated to insure against under this Lease, and each party on behalf of its insurer waives any right of subrogation that the insurer might otherwise have against the other party. The parties agree to cause their respective insurance companies insuring the premises or insuring their property on or in the premises to execute a waiver of any such rights of subrogation. 17. Condemnation. (a) The term "total taking" means the taking of the fee title or Landlord's master leasehold estate to so much of the premises or a portion of the Building necessary for Tenant's occupancy by right of eminent domain or other authority of law, or a voluntary transfer under the threat of the exercise thereof, that the premises are not suitable for Tenant's intended use. The term "partial taking" means the taking of only a portion of the premises or the Building which does not constitute a total taking as above defined. (b) If during the term hereof there shall be a total taking then this Lease, and the leasehold estate of Tenant in and to the premises, shall cease and terminate as of the date possession is taken. As used in this paragraph, the phrase date possession is taken means the date of taking actual physical possession thereof by the condemning authority or such earlier date as the condemning authority gives notice that it shall be deemed to have taken possession. (c) If during the term hereof there shall be a partial taking of the premises, this Lease shall terminate as to the portion of the premises taken on the date on which actual possession of the portion of the 11

premises is taken pursuant to the eminant domain proceedings and this Lease shall continue in full force and effect as the remainder of the premises. The minimum rent payable by Tenant for the balance of the term shall be abated in the ratio that the net rentable area of the premises taken bears to the net rentable area of the premises immediately prior to such taking, and Landlord shall make all necessary repairs or alterations to make the remaining premises a complete architectural unit, suitable for Tenant's permitted use hereunder. (d) All compensation and damages awarded for the taking of the premises, any portion thereof, or the whole or any portion of the common area or Building shall, except as otherwise herein provided, belong to and be the sole property of Landlord, and Tenant shall not have any claim or be entitled to any award for diminution in value of its rights hereunder or for the value of any unexpired term of this Lease; provided, however, that Tenant shall be entitled to make its own claim for, and receive separate award that may be made for Tenant's loss of business or for the taking of or injury to Tenant's improvements, or on account of any cost or loss Tenant may sustain the removal of Tenant's trade fixtures, equipment, and furnishings, or as a result of any alterations, modifications or repairs which may be reasonably required by Tenant in order to place the remaining portion of the premises, and for Tenant's moving relocation expenses not so condemned in a suitable condition for the continuance of Tenant's occupancy. The Tenant's award pursuant to this subparagraph shall not reduce Landlord's award. (e) If this Lease is terminated pursuant to the provisions of this paragraph 17, then all rentals and other charges payable by Tenant to Landlord hereunder shall be paid up to the date upon which possession shall be taken by the condemning agency and any rentals and other charges paid in advance and allocable to the period after the date possession is taken, and the parties shall thereupon be released from all further liability hereunder. 18. Compliance With Legal Requirements. Tenant shall at its sole cost and expense promptly comply with all laws, statutes, ordinances and governmental rules, regulations or requirements now in force or which may hereafter be in force, with the requirements of any board of fire underwriters or other similar body now or hereafter constituted, with any direction or occupancy certificate issued pursuant to any law by any public officer or officers, as well as the provisions of all recorded documents affecting the premises, as they relate to or affect the condition, use or occupancy of the premises, excluding requirements of structural changes not related to or affected by improvements made by or for Tenant or Tenant's use of the premises. 19. Assignment and Subletting. To the extent tenant occupies the majority of the space within the Premises and is not in default under the Lease, Tenant shall be permitted to sublease a minority of the space within the Premises to subagents and /or clients, without Landlord's prior consent. However, all such permitted sublessees shall abide by and comply with the terms and conditions of this lease. (a) Except for the aforementioned permitted subletting, Tenant shall not transfer, assign, sublet, enter into license or concession agreements, or hypothecate this Lease or the Tenant's interest in and to the premises without first procuring the written consent of Landlord, which consent shall not unreasonably be withheld, conditioned or delayed. Any such attempted transfer, assignment, subletting license or concession agreement or hypothecation without Landlord's consent shall be void and shall, at the option of Landlord, terminate this Lease. This Lease shall not, nor shall any interest herein, be assignable as to the interest of Tenant by operation of law without the consent of Landlord. Tenant agrees to reimburse Landlord for Landlords reasonable attorneys' fees incurred in conjunction with the processing and documentation of any such requested transfer, assignment, subletting, licensing or concession agreement, or hypothecation of this Lease or Tenant's interest in and to the premises. As it pertains to this Lease, any overage or other compensation above the base rental established herein paid to Tenant in any sublease or assignment shall belong in its entirety to Landlord. (b) Before entering into any assignment of this Lease or into a sublease of all or part of the Premises (other than a sublease permitted under this Lease without Landlord's prior consent), Tenant shall give written notice to Landlord identifying the intended assignee or subtenant by name and address and specifying the terms of the intended assignment or sublease. For a period of thirty (30) days after such notice is given, Landlord shall have the right by written notice to Tenant to (i) in the case of a proposed sublease, either (A) sublet from tenant any portion of the premises proposed to be sublet for the term for which such portion is proposed to be sublet but at the same rent as Tenant is required by pay to Landlord under this Lease for the same space, computed on a pro rata square footage basis, or (B) if the proposed subletting is for substantially the remaining period of the term of this Lease, terminate this Lease or terminate this Lease as is pertains to the portion of the premises so proposed by Tenant to be sublet, or (ii) in the case of a proposed assignment, terminate this Lease. If Landlord so terminates this Lease, such termination shall be as of the date specified in Landlord's notice. If Landlord so terminates this Lease, Landlord may, if it elects, enter into a new lease covering the premises or a portion thereof with the intended assignee or subtenant on such terms as Landlord and such person may agree, or enter into a new lease covering the premises or a portion thereof with any other person; in such event, Tenant shall not be entitled to any portion of the profit, if any, which Landlord may realize on account of such termination and reletting. Landlord's exercise of its aforesaid option shall not be construed to impose any 12

liability upon Landlord with respect to any real estate brokerage commission(s) or any other costs or expenses incurred by Tenant in connection with its proposed subletting or assignment. (c) If Tenant complies with the provisions of this section and Landlord does not exercise an option provided to Landlord under (b) above, Landlord's consent to a proposed assignment or sublet shall not be unreasonably withheld, conditioned or delayed. Without limiting the other instances in which it may be reasonable for Landlord to withhold its consent to an assignment or subletting, Landlord and Tenant acknowledge that is shall be reasonable for Landlord to withhold its consent in any of the following instances: (1) the proposed assignee or sublessee is a governmental agency; (2) in Landlord's reasonable judgment, the use of the premises by the proposed assignee or sublessee would entail any alterations which would lessen the value of the leasehold improvements in the premises, or would require material increased services by Landlord; (3) in Landlord's reasonable judgment, the financial worth of the proposed assignee or sublessee does not meet the credit standards applied by Landlord for other tenants under leases with comparable terms; (4) in Landlord's reasonable judgment, the character, reputation or business of tenant is inconsistent with the desired tenant-mix or the quality of other tenancies in the Building; (5) Landlord has received from any prior lessor to the proposed assignee or subtenant a negative report concerning such prior lessor's experience with the proposed assignee or subtenant; (6) Landlord has experienced previous defaults by or is in litigation with the proposed assignee or subtenant; (7) (i) the proposed assignee's or subtenant's anticipated use of the premises involves the generation, storage, use, treatment or disposal of Hazardous Material; (ii) the proposed assignee or subtenant has been required by any prior landlord, lender or governmental authority to take remedial action in connection with Hazardous Material contaminating a property if the contamination resulted from such assignee's or subtenant's actions or use of the property in question; or (iii) the proposed assignee or subtenant is subject to an enforcement order issued by any governmental authority in connection with the use, disposal or storage of a Hazardous Material; (8) the use of the premises by the proposed assignee or subtenant will violate any applicable law, ordinance or regulation; (9) the proposed assignment or sublease will create a vacancy elsewhere in the Building; (10) the proposed assignee or subtenant, or any person that, directly or indirectly, controls, is controlled by, or is under common control with the proposed assignee or subtenant, is then an occupant of the Building; (11) the proposed assignee or subtenant is a person with whom Landlord is negotiating to lease space in the Building; (12) the proposed assignment or sublease fails to include all of the terms and provisions required to be included therein pursuant to this paragraph; (13) Tenant is in default of any obligation of Tenant under this Lease, or Tenant has defaulted under this Lease on three (3) or more occasions during the twelve (12) months preceding the date that Tenant shall request consent; or (14) in the case of a subletting of less that the entire premises, if the subletting would result in the division of the premises into more than two subparcels or would require access to be provided through space leased or held for lease to another tenant or improvements to be made outside of the premises. (d) in the case of an assignment, 100% of any sums or other economic consideration received by Tenant as a result of such assignment shall be paid to Landlord after first deducting the unamortized cost of leasehold improvements paid by Tenant, and the cost of any real estate commissions incurred in connection with such assignment. In the case of a subletting, 100% of any sum or economic consideration received by Tenant as a result of such subletting shall be paid to Landlord after first deducting (1) the rental due hereunder, prorated to reflect only rental allocable to the sublet portion of the premises, and (2) the cost of any real estate commissions incurred in connection with such subletting, amortized over the term of the sublease. Upon Landlord's request, Tenant shall assign to Landlord all amounts to be paid to Tenant by any such subtenant or assignee and shall direct such subtenant or assignee to pay the same directly to Landlord. (e) Notwithstanding the provisions of subparagraphs (a) and (b) above, Tenant may assign this Lease or sublet the premises or any portion thereof, without Landlord's consent, to any corporation which controls, is controlled by or is under common control with Tenant or to any corporation resulting from the merger or consolidation with Tenant so long as there is no change in control of Tenant, provided that said assignee assumes, in full, the obligations of Tenant under this Lease. (f) Regardless of Landlord's consent, no subletting, assignment, hypothecation, license or concession shall release Tenant of Tenant's obligation or alter the primary liability of Tenant to pay the rental and to perform all other obligations to be performed by Tenant hereunder. The acceptance of rental by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision hereof. Consent to one assignment, subletting, hypothecation, license or concession agreement shall not be deemed consent to any subsequent assignment, subletting, hypothecation, license or concession agreement. In 13

the event of default by any assignee of Tenant or any successor of Tenant in the performance of any of the terms hereof, Landlord may proceed directly against Tenant without he necessity of exhausting remedies against such assignee or successor. Landlord may consent to subsequent assignments or modifications to this Lease, with assignees of Tenant without notifying Tenant or any successor of Tenant, and without obtaining its or their consent thereto and such action shall not relieve Tenant of liability under this Lease. (g) Each transfer, assignment, subletting, license, concession agreement and hypothecation to which there has been consent or which has been permitted pursuant to subparagraph (e) above, shall be by an instrument in form satisfactory to Landlord and shall be executed by the transferor, assignor, sublessor, licenser, concessionaire, hypothecator or mortgagor and the transferee, assignee, sublessee, licensee, concessionaire or mortgagee in each instance, as the case may be; and each transferee, assignee or sublessee shall agree in writing for the benefit of Landlord to assume, to be bound by, and to perform the terms, covenants and conditions of this Lease to be done, kept and performed by Tenant. One executed copy of such instrument shall be delivered to Landlord. No sublessee other than Landlord shall have the right further to sublet. (h) In the event Tenant shall assign or sublet the premises or request Landlord's consent to a proposed assignment, subletting, or other act, then Tenant shall pay (i) to Landlord and administrative fee in the sum of $300 and (ii) Landlord's reasonable attorneys' fees incurred in connection therewith. (i) For the purpose of this Lease, a transfer of more than (i) 50% of the partnership interest in Tenant if Tenant is a partnership, or (ii) 50% of the outstanding voting stock if Tenant is a corporation, shall constitute an assignment of this Lease. Notwithstanding anything to the contrary in the Lease, the terms of this Section 19 (i) shall not apply to Tenant if Tenant is a publicly traded company. Further, an initial public trading of Tenant's stock shall not constitute an assignment or transfer for purposes of this Section 19 (i). 20. Rules and Regulations. Tenant shall faithfully observe and comply with the rules and regulations attached to this Lease as Exhibit C and, after notice thereof, all reasonable modifications thereof and additions thereto from time to time promulgated in writing by Landlord. Landlord shall not be responsible to Tenant for the nonperformance by any other tenant or occupant of the Building of any of such rules and regulations. 21. Landlord's Access. Landlord may enter the premises at reasonable hours with reasonable advance notice to (1) inspect he same; (2) exhibit the same to prospective purchasers, mortgagees or tenants; (3) determine whether Tenant is complying with all its obligations hereunder; (4) supply any service to be provided by Landlord to Tenant hereunder; (5) post notices of non-responsibility; (6) post "to Lease" signs of reasonable size upon the premises during the last 90 day of the term hereof; and (7) make repairs required of Landlord under the terms hereof or repairs to any adjoining space or utility services or make repairs, alterations or additions to the premises or any other portion of the Building, provided, however, that all such work shall be done as promptly as reasonably possible and so as to cause as little interference to Tenant as reasonably possible and that any repairs, alterations, or additions to the premises shall, when completed, not materially and adversely affect Tenant's use of the premises. Landlord shall at all times have and retain a key with which to unlock all of the doors in, on or about the premises (excluding Tenant's vaults, safes and similar areas designated in writing by Tenant in advance) and Landlord shall have the right to use any and all means which Landlord may deem proper to open such doors in an emergency in order to obtain entry to the premises. Any entry to the premises obtained by Landlord by any of such means shall not under any circumstances be construed or deemed to be a forcible or unlawful entry into or a detainer of the premises or an eviction, actual or constructive, of Tenant from the premises, or any portion thereof. 22. Default. If: (1) Tenant shall fail to pay any rent or other sum payable hereunder for a period of 10 days after written notice from Landlord and the same is due; (2) Tenant shall fail to observe, keep or perform any of the other terms, covenants, agreements or conditions contained herein or in the rules and regulations to be observed or performed by Tenant and such default continues for a period of 30 days after notice by Landlord or beyond the time reasonably necessary for cure if such default is of a nature to require in excess of 30 days to remedy; (3) Tenant shall become bankrupt or insolvent, or make an assignment for the benefit of creditors, or take or have taken against Tenant any proceedings of any kind under any provision of the Federal Bankruptcy Act or under any other insolvency, bankruptcy or reorganization act or, in the event any such proceedings are involuntary, such involuntary proceedings are not dismissed within 60 days thereafter; (4) a receiver is appointed for a substantial part of the assets of Tenant; (5) Tenant shall vacate or abandon the premises; or (6) this Lease or any interest of Tenant hereunder shall be levied upon by any attachment or execution, then any such event shall constitute an event of default by Tenant. Upon the occurrence of any event of default by Tenant hereunder, Landlord may, at its option and without any further notice or demand, in addition to any other rights and remedies given hereunder or by law, do any of the following: 14

(a) Landlord shall have the right, so long as such default continues, to give notice of termination to Tenant. On the date specified in such notice (which shall not be less than 3 days after the giving of such notice) this Lease shall terminate. (b) In the event of any such termination of this Lease, Landlord may then or at any time thereafter, re-enter the premises and remove therefrom all persons and property and again repossess and enjoy the premises, without prejudice to any other remedies that Landlord may have by reason of Tenant's default or of such termination. c) The amount of damages which Landlord may recover in event of such termination shall include, without limitation, (1) the amount at the time of award of (A) unpaid rental earned and other sums owed by Tenant to Landlord hereunder, as of the time of termination, together with interest thereon as provided on this Lease, (B) the amount by which the unpaid rent which would have been earned during the period from termination until the award exceeds the amount of such rental loss that Tenant proves could be reasonably avoided and (C) the amount by which the unpaid rent for the balance of the term after the time of the award exceeds the amount of such rental loss that Tenant proves could be reasonably avoided (computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award pus one percent), (2) all legal expenses and other related costs incurred by Landlord following Tenant's default including reasonable attorneys' fees incurred in collecting any amount owed hereunder, (3) all costs incurred by Landlord in restoring the premises to good order and condition, or in remodeling, renovating or otherwise preparing the premises for reletting, and (4) all costs (including without limitation any brokerage commissions) incurred by Landlord in reletting the premises. For the purpose of determining the unpaid rent in the event of a termination of this Lease, the monthly rent reserved in this Lease shall be deemed to be the sum of (1) the minimum rent and (2) the Operating Expense charge and any other amounts last payable by Tenant pursuant to paragraphs 5, 6, 7, 10, 13, and 16 above. (d) Following the termination of this Lease or Tenant's right of possession hereunder (or upon Tenant's failure to remove its personal property from the premises after the expiration of the term of the Lease), Landlord may remove its personal property from the premises after the expiration of the term of such property in a public or private warehouse or elsewhere at the sole cost and expense of Tenant; such Wharehouser shall have all rights and remedies provided by law against Tenant as the owner of such property. In addition, in the event that Tenant shall not immediately pay the cost of storage of such property after the same has been stored for a period of 30 days or more, Landlord may sell any or all thereof at a public or private sale in such manner and at such times and places as Landlord in its sole discretion may deem proper, without notice to or demand upon Tenant. Tenant waives all claims for damages that may be caused by Landlord's removing or storing or selling the property as herein provided, and Tenants shall indemnify and hold Landlord free and harmless for, from and against any and all losses, costs and damages, including without limitation all costs of court and attorneys' fees of Landlord occasioned thereby. (e) Landlord shall have the right to cause a receiver to be appointed in any action against Tenant to take possession of the premises and to collect the rents or profits derived therefrom. The appointment of such receiver shall not constitute an election on the part of Landlord to terminate this Lease unless notice of such intention is given to Tenant. (f) Even though Tenant has breached this Lease and/or abandoned the premises, this Lease shall continue in effect for so long as Landlord does not terminate this Lease, and Landlord may enforce all its rights and remedies under this Lease, including the right to recover the rental in periodic actions as it becomes due under this Lease. In such event, Landlord may re-enter the premises and remove all persons and property if the premises have not been vacated, using any available summary proceedings, without such re-entry or removal being deemed a termination or acceptance of surrender of this Lease. Landlord may then elect to relet the premises for the account of Tenant for a period which may extend beyond the term hereof, and upon such other terms as Landlord may reasonably deem appropriate. Tenant shall reimburse Landlord upon demand for all costs incurred by Landlord in connection with such reletting, including, without limitation, necessary restoration, renovation, or improvement costs, reasonable attorneys' fees and brokerage commissions. The proceeds of such reletting shall be applied first to any sums then due and payable Landlord from Tenant, including the reimbursement described above. In balance, if any, shall be applied to the payment of future rent as it becomes due hereunder. 23. Landlord's Right to Cure Default. All covenants and agreements to be performed by Tenant under any of the terms of this Lease shall be at its sole cost and expense and without any abatement of rent. If Tenant shall fail to pay any sum of money, other than rent, required to be paid by it hereunder or shall fail to perform any other act on its part to be performed hereunder and such failure shall have become an event of default under paragraph 22 above, Landlord may, but shall not be obligated to do so, and without waiving or releasing Tenant from any obligations of Tenant, make any such payment or perform any such other act on Tenant's part to be made or performed as in this Lease provided. All sums so paid by Landlord and all necessary incidental costs shall be deemed additional rent hereunder and shall be payable 15

to Landlord on demand together with Default Interest from the date of expenditure by Landlord until repaid. 24. Attorneys' Fees. If as a result of any breach or default in the performance of any of the provisions of this Lease or in order to enforce its rights hereunder, Landlord uses the services of an attorney in a nonjudicial action, at trial, or upon an appeal, to secure compliance with such provisions or recover damages therefor, to exercise such rights, or to terminate this Lease or evict Tenant, Tenant shall reimburse Landlord upon demand for any and all reasonable attorneys' fees and expenses so incurred by Landlord if Landlord prevails. If tenant shall be the prevailing party in any legal action brought by Landlord against Tenant, Tenant shall be entitled to recover for the fees of its attorneys in such an amount as the court may adjudge reasonable. Tenant, to the extent permitted by law, does hereby waive any further right to attorneys' fees provided by applicable state or federal law. 25. Subordination. a) This Lease shall be subject and subordinated at all times to all ground or underlying leases which may hereafter be executed affecting the Building, and the lien of all mortgages and deeds of trust in any amount or amounts whatsoever now or hereafter placed on or against the Building or on or against Landlord's interest or estate therein or on or against all such ground or underlying leases, all without the necessity of having further instruments executed on the part of Tenant to effectuate such subordination. Notwithstanding the foregoing (1) in the event of termination for any reason whatsoever of any ground or underlying lease hereafter executed, this Lease shall not be barred, terminated, cut off or foreclosed nor shall the rights and possession of Tenant hereunder be disturbed if Tenant shall not then be in default in the payment of rental or other sums or be otherwise in default under the terms of this Lease, and Tenant shall attorn to the Landlord of any such ground or underlying Lease, or, if requested, enter into a new lease for the balance of the original or extended term hereof then remaining upon the same terms and provisions as are in this Lease contained; (2) in the event of a foreclosure of any such mortgage or deed of trust hereafter executed or of any other action or proceeding for the enforcement thereof, or of any sale thereunder, this Lease will not be barred, terminated, cut off or foreclosed nor will the rights and possession of Tenant thereunder be disturbed if Tenant shall not then be in default in the payment of rental or other sums or be otherwise in default under the terms of this Lease, and Tenant shall attorn to the purchaser at such foreclosure, sale or other action or proceeding; and (3) Tenant agrees to execute and deliver upon demand such further reasonable instruments, as determined by Landlord and/or lender, evidencing such subordination of this Lease, ground or underlying leases, and to the lien of any such mortgages or deed of trust as may reasonably be required by Landlord. Tenant's covenant to subordinate this Lease to ground or underlying leases, and mortgages or deeds of trust hereafter executed is conditioned upon each such senior instrument containing the commitments specified in the preceding clauses (1) and (2); and (4) Tenant further waives the provisions of any statute of rule of law, now or hereafter in effect, which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect the Lease and the obligations of Tenant hereunder in the event of such foreclosure or sale. (b) Tenant shall mail by certified or registered post, return receipt requested, or personally deliver to any Landlord under a ground lease or mortgage lender a duplicate copy of any and all notices in writing which Tenant may from time to time give to or serve upon Landlord pursuant of the provisions of this Lease, and such copy shall be mailed or delivered at, or as near as possible to, the same time such notices are given or served by Tenant. No notice by Tenant to Landlord hereunder shall be deemed to have been given unless and until a copy thereof shall have been so mailed or delivered to any ground lease landlord or mortgage lender. Upon the execution of any ground lease or mortgage, Tenant shall be informed in writing of the vesting of the interest evidenced by the ground lease or mortgage. (c) Should any event of default by Landlord under this Lease occur, any ground lease landlord or mortgage lender shall have 30 days after receipt of written notice from Tenant setting forth the nature of such event of default within which to remedy the default; provided that in the case of a default which cannot with due diligence be cured within such 30-day period, the ground lease landlord or mortgage lender shall have the additional time reasonably necessary to accomplish the cure, provided that (i) it has commenced the curing within such 30 days and (ii) thereafter diligently prosecutes the cure to completion. If the default is such that the possession of the premises may be reasonably necessary to remedy the default, any ground lease landlord or mortgage lender shall have a reasonable additional time after the expiration of such 30-day period within which to remedy such default, provided that (i) it shall have fully cured any default in the payment of any monetary obligations of Landlord under this Lease within 30 day period and shall continue to pay currently such monetary obligations as and when the same are due and (ii) it shall have acquired Landlord's estate or commenced foreclosure or other appropriate proceedings within such period, or prior thereto, and is diligently prosecuting any such proceedings. 26. No Merger. The voluntary or other surrender of this Lease by Tenant, or a mutual cancellation thereof, shall not work a merger, and shall, at the option of Landlord, terminate all or any existing 16

subleases or subtenancies, or may, at the option of Landlord, operate as a assignment to it of any or all such subleases or subtenancies. 27. Sale by Landlord. In the event the original Landlord hereunder, or any successor owner of the Building, shall sell or convey the Building, all liabilities and obligations on the part of the original Landlord, or such successor owner, under this Lease accruing thereafter shall terminate, and thereupon all such liabilities and obligations shall be binding upon the new owner. Tenant agrees to attorn to such new owner. 28. Estoppel Certificate. At any time from time to time, but on not less than 10 days prior notice by Landlord, Tenant will execute, acknowledge and deliver to Landlord, promptly upon request, a certificate certifying (a) that this Lease is unmodified and in full force and effect (or, if there have been modifications, that his Lease is in full force and effect, as modified, and stating the date and nature of each such modification), (b) the date, if any, to which rental and other sums payable hereunder have been paid, (c) that no notice has been received by tenant of any default which has not been cured, except as to defaults specified in said certificate, and (d) such other matters as may be reasonably requested by Landlord and/or lender. Tenant agrees it shall execute an estoppel certificate which is consistent with the terms and conditions of the lease and which does not modify or lessen Tenant's position in the lease. Tenant hereby appoints Landlord as Tenant's attorney-in-fact to execute, acknowledge and deliver such certificate if Tenant shall fail to do so within the above-prescribed time period. Any such certificate may be relied upon by any prospective purchaser, mortgagee of beneficiary under any deed or trust of the Building. 29. Holdover Tenancy. If, without objection by Landlord, Tenant holds possession of the premises after expiration of the term of this Lease, Tenant shall become a Tenant from month to month upon all of the terms specified in thi s Lease as applicable immediately prior to expiration of such term, except that minimum rent will be 150% of that applicable immediately prior to expiration of such term. Each party shall give the other notice of its intention to terminate such tenancy at least one month prior to the date of such termination. 30. Building Security. (a) Landlord shall have the right, but not the obligation, from time to time to adopt such policies, procedures and programs as it shall deem necessary or appropriate for the security of the Building, and Tenant shall cooperate with Landlord in the enforcement of the policies, procedures and programs adopted by Landlord. (b) Without limiting the generality of subparagraph (a) above, Landlord reserves the right to exclude from the Building between the hours of 6 p.m. and 7 a.m. and at all hours on Saturdays, Sundays and holidays all persons who do not present a valid pass to the Building. If Landlord does elect to adopt such pass system, Landlord shall furnish passes to persons for whom Tenant requests the same in writing, and Tenant shall be responsible for all person for whom it request passes and shall be liable to Landlord for all acts of such persons. Landlord shall in no case be liable for damages for any error with regard to the admission to or exclusion form the Building of any person. In case of invasion, mob, riot, public demonstration or other circumstances rendering such action advisable in Landlord's opinion, Landlord reserves the right to prevent access to the Building during the continuance of the same by such action as Landlord may deem appropriate, including closing doors. (c) In the event of any picketing, public demonstration or other threat to the security of the Building that is directly attributable to Tenant, Tenant shall reimburse Landlord for any costs incurred by Landlord in connection with such picketing, demonstration or other threat in order to protect the security of the Building. 31. Parking. (a) Any parking areas appurtenant or within the Building, or designated portions thereof, shall be available for the use of Tenants of the Building, and, to the extent designated by Landlord, the employees, agents, customers and invitees of said tenants, subject to the rules, regulations, charges, and rates as set forth by the Landlord from time to time (see attached); provided, however, that Landlord may restrict to certain portions of the parking areas, parking for Tenant or other tenants of the Building and their employees and agents, and may designate other areas to be used only by customers and invitees of Tenants of the Building. Notwithstanding anything herein contained, Landlord reserves the right from time to time to make reasonable changes in, additions to, and deletions from parking areas as now or hereafter constituted. (b) Landlord, or its agents, shall have the right to cause to be removed any cars, trucks, trailers or other motorized or nonmotorized vehicles of tenants, its employees, agents, guests or invitees that are parked in violation hereof or in violation of regulations of the Building, without liability of any kind to Landlord, its agents or employees, and Tenant agrees to hold Landlord harmless from and defend it 17

against any and all claims, losses, or damages and demands asserted or arising in respect to or in connection with the removal of any such vehicles as aforesaid. Tenant shall from time to time upon request of Landlord supply Landlord with a list of license plate numbers of all vehicles owned by its employees and agents who are to have parking privileges hereunder. Landlord may, as a part of the regulations promulgated by it for the use of the parking areas, require that Tenant cause any identification sticker issued by Landlord to be affixed to the bumpers or other designated location on all vehicles of Tenant and its employees and agents who are authorized to park in the parking areas. 32. Security Deposit. If any security deposit has been made herewith, which sum is specified in the Basic Lease Information (the "Deposit"),Tenant and Landlord shall treat such sum as a security deposit and not a last month's rent. The Deposit shall be held in a co-mingled account by Landlord, as security for the faithful performance by Tenant of all of the provisions of the Lease to be performed or observed by Tenant. If Tenant fails to pay rent or other charges due hereunder, or otherwise defaults with respect to any provision of this Lease, Landlord may use, apply or retain all or any portion of the Deposit for the payment of any rent or other charge in default or for reason of Tenant's default, or compensate Landlord for any loss or damage which Landlord may suffer thereby. If Landlord so uses or applies all or any portion of the Deposit, Tenant shall within ten (10) days after demand therefore deposit cash with Landlord in an amount sufficient to restore the Deposit to the full amount thereof and Tenant's failure to do so shall be a material breach of this Lease. Landlord shall not be required to keep the Deposit separate from its general accounts. If Tenant performs all of Tenant's obligations hereunder, the Deposit, or so much thereof as has not theretofore been applied by Landlord, shall be returned, without payment of interest or other increment for its use, to Tenant (or, at Landlord's option, to the last assignee, if any, of Tenant's interest hereunder) at the expiration of the Term hereof, and after Tenant has vacated the Premises. No trust relationship is created herein between Landlord and Tenant with respect to the Deposit. 33. No Partnership. It is expressly understood that Landlord does not, in any way or for any purpose, become a partner of Tenant in the conduct of its business, or otherwise, or joint venture or a member of a joint enterprise with Tenant. 34. Recording. Tenant shall not record this Lease without the prior written consent of Landlord. 35. Modification and Financing Conditions. Landlord may have obtained financing and may seek to obtain further financing for the Building, portions thereof, and the operation thereof, secured by mortgages or deeds of trust encumbering the Building. Landlord may also elect to enter into a ground lease of the Building. If any mortgage lender should require, as a condition to such financing, or pursuant to rights of approval set forth in the mortgage or deed of trust encumbering the Building, or if any ground lease should require, as a condition to such ground lease or pursuant to rights of approval set forth therein, any modification of the terms or conditions of this Lease, Tenant agrees to execute such modification or amendment, provided that, such modification or amendment (a) shall not increase the rental or Tenant's share of any costs in addition to minimum rent or increase any other Tenant obligation or reduce any right under the terms hereof which are not provided for hereunder, (b) shall not materially interfere with Tenant's use or occupancy, and (c) if requested by a mortgage lender with a lien on the Building or a ground lessee pursuant to a ground lease effective as of the date hereof, shall have been requested prior to 30 days after the date hereof. If Tenant should refuse to execute any modifications so required within 10 days after receipt of same, Landlord shall have the right by notice to Tenant to cancel this Lease, and upon such cancellation Landlord shall refund any unearned rental or security deposit, and neither party shall have any liability thereafter accruing under this Lease, except as provided in paragraph 15 above. 36. Waiver.

If any such IP Claim involves other vendors of Verizon Wireless, CTS shall cooperate as reasonably necessary to effectively defend Verizon Wireless. Verizon Wireless shall, at CTS's expense, reasonably cooperate with CTS in the defense of Verizon Wireless. The omission of Verizon Wireless to provide notice to CTS of any such action shall not relieve CTS from any liability in respect of such action which it may have to Verizon Wireless on account of the indemnity agreement contained in this Section 1.13, except to the extent CTS may have been prejudiced by the failure to give notice. 1.13.3 If the use, manufacture, sale, or importation in the United States of any Product or Service furnished hereunder becomes subject to an IP Claim, CTS shall, at Verizon Wireless' option and at no expense to Verizon Wireless, (i) by license or other release from claim of infringement obtain for Verizon Wireless and Verizon Wireless' customers the right to make, use, sell and/or import into the United States the Product or Service, as appropriate; or (ii) substitute an equivalent non-infringing Product or Service reasonably acceptable to Verizon Wireless, which meets the specifications for the Product or Service, and extend this indemnity thereto; or (iii) modify such Product or Service to make it non-infringing but continue to meet the specifications therefore, and extend this indemnity thereto; or (iv) accept the return of the Product or Service and reimburse Verizon Wireless the purchase price therefore, less a reasonable charge for reasonable wear and tear, and release Verizon Wireless from all future payments under this Agreement. 1.14 PLANT RULES AND SECURITY REQUIREMENTS. 17 Verizon Wireless/CTS Agreement CONFIDENTIAL

CTS warrants that any service outage of the CTS Network will not exceed twenty-four (24) hours in duration for so long as Verizon Wireless has a Connected System, provided that CTS shall have no liability under this section to the extent that the service outage or any delay in CTS meeting its obligations under this section is due, in whole or part, to any cause beyond CTS's reasonable control or any cause that is not attributable to the CTS Network. If CTS breaches the foregoing warranty, then, as Verizon Wireless' exclusive remedy for such breach, CTS shall provide Verizon Wireless with a credit equal to $450.00 per 24-hour period for each additional 24-hour period that the service outage continues after the initial 24 hours of the service outage. b. Intellectual Property Rights. CTS hereby warrants to Verizon Wireless that, subject to the provisions of Section 4.1 below, each Licensed Program (not including any Third-Party Software), if used by Verizon Wireless in accordance with the terms of this Agreement, is free of any valid claim by a Third Party that such Licensed Program (not including any Third-Party Software) infringes an existing United States Intellectual Property Right of such Third Party.

For each System, CTS hereby warrants to Verizon Wireless that the Licensed Programs (not including any Third-Party Software), when used in conjunction with the Hardware necessary for operation of such System and with Verizon Wireless' cellular network operating in a normal manner, and when all relevant Infrastructure and Environmental Requirements are satisfied, will materially perform in accordance with their Specifications for so long as the Support Services Agreement is in full force and effect. Verizon Wireless' exclusive remedy for breach of such warranty shall be correction by CTS, at no additional charge to Verizon Wireless, of any errors or malfunctions in such Licensed Programs found not to be in compliance with such warranty, in accordance with the terms of the Support Services Agreement; provided, that CTS shall have no obligation to make such corrections if Verizon Wireless is in breach or default under this Agreement and is notified, in writing, of such breach or default, or if Verizon Wireless fails to notify CTS in writing within a reasonable time of discovery of such errors or malfunctions. If a correction of an error or malfunction is commercially impractical, CTS may provide Verizon Wireless with a commercially reasonable circumvention of such error or malfunction. For Third-Party Software supplied by CTS, CTS will pass through to Verizon Wireless the warranties that CTS receives from its vendor for such Third-Party Software, to the extent that such vendor will honor such warranties. d.

2.2.1 CTS Technical Support Hotline. a. General. CTS will maintain a technical support hotline to respond to all technical problems with respect to the System. The current technical support hotline number is (206) 727-6353, and is subject to change with notice to Verizon Wireless. Automatic call distribution will route calls to an available CTS technical analyst. If a technical analyst is not available, the caller will be either routed to a voice mailbox, or asked to hold via a wait queue. Depositing a message in the voice mailbox activates an internal paging system, and the next available technical analyst will promptly return the call during the applicable hours of coverage. Except as otherwise provided under Section 2.7.2 below, CTS technical analysts will be able to access to the System via a 56 Kbps connection, and will be able to query the System while a Support Contact is on line. If CTS determines at any time that any CTS on-site technical support is necessary due to the nature of a particular condition or recurring similar conditions, then CTS will make available such personnel as CTS deems appropriate to respond to the condition, so long as Verizon Wireless provides CTS with adequate facilities for such personnel as required by Section 2.7.4 below. Support services include CTS standard automated daily reports; disc space allocation and maintenance; VDD, NPA/NXX, gold list updates and fingerprint database reconciliations based on files sent from Verizon Wireless to CTS in the specified formats; event log maintenance; DCC and Control Channel updates at the RPC as requested by the Verizon Wireless; and Sybase upgrades. Support services also include renaming cell sites performed one day during each quarter of 2001 in a bundled fashion up to 25 sites each quarter. Verizon Wireless will provide CTS with the complete rename information one week in advance of the day the renames are to be performed. Requests for renaming sites on additional dates or in excess of 25 per quarter will be charged in accordance with Section 1.5.4(b). b. Commencement of Support. CTS's responsibility to address conditions that affect the System will commence upon CTS's receipt of a telephone call from a Support Contact (via the technical support hotline) identifying the condition to CTS. The CTS technical analyst responding to the call will perform the following during the applicable hours of coverage: (i) identify the condition; and (ii) assess whether the condition is a Priority 1 Incident, Priority 2 Incident, or Priority 3 Incident. Once the above factors are identified, CTS will respond to and resolve the condition as described in Section 2.2.2 below. c. Hours of Coverage. CTS technical analysts will be available during Normal Business Hours to provide the technical support described in this Section 2.2. 2.2.2 Response and Resolution Procedures. a. CTS's response and resolution procedures for conditions that affect the System are determined by the severity of the condition (i.e., Priority 1 Incident, Priority 2 Incident, and Priority 3 Incident), as described in this Section 2.2.2. Response to a condition will involve an initial period for identification of the source of the problem, which may require Verizon 25 Verizon Wireless/CTS Agreement CONFIDENTIAL

Wireless' assistance, including, without limitation, assistance with inspecting the condition of Hardware, cooperative troubleshooting with respect to network connectivity, and providing sufficient examples of any anomalies reported with System data or functioning. b. Priority 1 Incident. If CTS determines that a Priority 1 Incident has occurred, CTS will begin working to identify the source of the problem within one (1) normal business hour after commencement of CTS support (as described in Section 2.2.1(b)) for the Priority 1 Incident and will continue to work on identifying the source of the problem during Normal Business Hours until the problem is identified. If the problem is identified as a problem with any Supported Product, CTS will work to correct the problem as follows: i. Problem identified with Licensed Programs: CTS will work to correct the problem during Normal Business Hours until (i) a reasonably satisfactory correction is achieved or (ii) CTS determines that a correction is commercially impractical, in which case CTS will then work to provide Verizon Wireless with a commercially reasonable circumvention of the problem. ii. Problem identified with Hardware: CTS's responsibilities for correcting Hardware problems will be determined by the type of Hardware and Verizon Wireless' selection of hardware maintenance. If a Priority 1 Incident, (a) occurs in Los Angeles, San Francisco, Sacramento or Atlanta, or (b) occurs in any two markets simultaneously, then CTS shall have ten (10) business days from the time it is notified to resolve such Priority 1 Incident. Otherwise, CTS will be deemed to have materially breached this Agreement. , CTS shall have no liability under this Section to the extent that (a) the condition or any delay in CTS meeting its obligations under this Section is due in whole or in part, to any cause beyond CTS's reasonable control or cause that is not attributable to any System, or (b) the condition pertains to the CTS-Certified Hardware described in Section 2.4.2(d), below. In the event such cause is out of CTS's reasonable control, CTS shall provide Verizon Wireless written notice of such cause and shall seek Verizon Wireless approval/waiver of this provision, such approval will not be unreasonably withheld by Verizon Wireless. c. Priority 2 Incident. If CTS determines that a Priority 2 Incident has occurred, CTS will begin working to identify the source of the problem within nine (9) normal business hours after commencement of CTS support (as described in Section 2.2.1.(b)) for the Priority 2 Incident and will continue to work on identifying the source of the problem during CTS's Normal Business Hours until the problem is identified.

is identified as a problem with any Supported Products, CTS will work to correct the problem as set forth in Section 2.2.2(b) above. 2.2.3 Maintenance Releases. CTS may provide Maintenance Releases to Verizon Wireless for such System at no additional charge, so long as Verizon Wireless is not in default of its payment obligations hereunder. Maintenance Releases, if provided, will be delivered to each site, either via tape, diskette media, or network connection, as determined by CTS in consultation with Verizon Wireless. 2.2.4 Changes in Condition. If the severity of a condition requiring Support Services hereunder changes (e.g., a Priority 2 Incident becomes a Priority 1 Incident due to a change in relevant circumstances), then the timeframes governing CTS's response and resolution of the problem will be modified accordingly to comport with the timeframes for the new level of priority as outlined in Section 2.2.2 above. The applicable new timeframes will be measured from the time at which CTS receives notification of the change in condition. 2.3 SOFTWARE SUBSCRIPTION SERVICES. CTS will provide New Releases to Verizon Wireless for such System at no additional charge, so long as Verizon Wireless is not in default of its payment obligations hereunder. New Releases, if provided, will be delivered to each site, either via tape, diskette media, or network connection, as determined by CTS in consultation with Verizon Wireless. If Verizon Wireless does not pay CTS the Aggregate Fee as set forth in Section 1.5.3, above, then CTS, in its discretion, may provide New Releases for such System to Verizon Wireless on such terms and conditions and for such fees as the parties may mutually agree to in writing. 2.4 CELL SITE HARDWARE MAINTENANCE. 2.4.1 CTS On-Site Maintenance. a. Maintenance. For those markets shown on Exhibit A in which Verizon Wireless has selected CTS On-Site Maintenance, CTS will perform the Support Services described in this Section 2.4.1 with respect to the Cell Site Hardware for a System.
