NOTE E- SEGMENT INFORMATION: The Company had two reportable business segments for the three-month period ended March 31, 2001 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-Communications, Inc. Management evaluates segment performance based upon segment profit or loss before income taxes. The difference in the pretax segment loss of $48,000 and net loss of $50,000 for the three months ended March 31, 2001 is attributable to income tax expense of $2,000. The difference between pretax segment income of $692,000 and net income of $666,000 for the three months ended March 31, 2000 is attributable to income tax expense of $15,000 and minority interest of $11,000. There were no inter-company sales of products between the segments.

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 1,500 cell sites in many 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. 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 offices in Los Angeles, Boston and Chicago. Future Opportunities For Growth In Emerging Technologies 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 in a stock-for-stock transaction. The Company's total investment in TruePosition, Inc. common stock at March 31, 2001 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 Page 8

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 has completed design of the initial product suite and is currently in the final testing phases. Revenue and Expense Revenue During the first three months of 2001, the Company generated revenue from two sources: Isis pre-paid phone card product sales and 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 Statement of Financial Accounting Standard ("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. 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. 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. There was no systems revenue in the first quarter of 2001. 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 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. 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 element 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, services and systems are primarily comprised of the costs of: (i) prepaid phone card activation 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 Page 9

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 maintenance processes; (iv) enhance its customer support capabilities; and (v) enhance its general and administrative activities. Three months ended March 31, 2001 compared to three months ended March 31, 2000 Overview Total revenue increased 13% to $5,561,000 in 2001 from $4,917,000 in 2000. Net loss was ($50,000), or ($0.02) per diluted share, in 2001 compared to net income of $666,000, or $0.28 per diluted share, in 2000. The Company recorded alternative minimum tax expense of $2,000 and $15,000 during the 2001 and 2000 periods, respectively. The increased revenue was primarily derived from the Company's prepaid phone card business, which commenced operations in December 1999, and which provided $4.2 million in revenue in the first quarter of 2001, compared to $2.7 million in revenue in the comparable 2000 period. This increase was offset by decreased systems and service revenue primarily from the Company's Blackbird Platform products due to: (i) a reduction in domestic market opportunities for the Company's cloning fraud prevention technology, (ii) the effectiveness of this and other authentication-based products in combating cloning fraud, (iii) lower penetration than originally planned of Blackbird Platform Products into existing customers' markets and new and/or additional markets, (iv) the lack of additional new domestic and international customers, and (v) the lack of any systems upgrades in the current period compared to the prior year period. The $0.7 million decrease in net income is due to several factors. The Blackbird business is a relatively smaller business segment in Q1 2001 compared to Q1 2000, as revenue decreased by $0.8 million. Blackbird costs and expenses decreased by $0.5 million, resulting in a net profit reduction of $0.3 million. The Isis phone card business had a segment loss of $0.3 million in the current quarter, compared to breakeven in the comparable prior year quarter. This profit reduction was due to $0.1 million in reduced gross margins as the business has become more competitive, and to increased operating expenses of $0.2 million as ISIS' three sales offices were fully-staffed during the current quarter, while in the comparable 2000 period the business was still in the start-up phase. Interest income was lower by $0.1 million in the 2001 quarter compared to the 2000 period. Revenue Prepaid phone card revenue was $4,156,000 in 2001, compared to $2,747,000 in 2000. The Company began selling phone cards in late 1999 and the growth in revenue is due to greater market penetration in 2001 compared to 2000. Service revenue decreased 26% to $1,405,000 in 2001 from $1,895,000 in 2000. All of the 2001 and 2000 service revenue was derived from the Blackbird Platform Products. The decrease is due to the factors discussed above. The Company anticipates that service revenue will continue to decrease in future periods due to the anticipated reduction in the installed base of Blackbird Platform Products by wireless carriers as the product line rapidly approaches the later stages of its service life. Systems revenue was $0 in 2001, a decrease from $275,000 in 2000 due to the factors discussed above. The Company does not currently anticipate any future Blackbird systems revenue. Costs and Expenses Costs of phone cards, services and systems increased by $1,199,000 to $4,354,000 in first quarter of 2001, from $3,155,000 in the same period of 2000. As a percent of total revenue, the costs were 78% and 64% for the 2001 and 2000 periods, respectively. The increase in the amounts and percentages of costs for 2001 relative to 2000 is primarily due to the prepaid Page 10

phone card business being a larger percentage of the Company's overall business with lower gross margins compared to the Company's Blackbird service product offerings. Sales and marketing expenses increased 30% to $406,000 in 2001 from $313,000 in 2000. As a percent of total revenue, the costs were 7% and 6% for the 2001 and 2000 periods, respectively. The increase in sales and marketing expenses is attributable to costs in selling and marketing prepaid phone cards and additional spending during the first quarter of 2001 for the introduction of the Company's Neumobility product line, offset by a decrease in sales and marketing expenses for the Blackbird Platform products. General and administrative expenses decreased 21% to $442,000 in 2001 from $558,000 in 2000, primarily due to headcount reductions in comparison to the prior year period. Research and development costs increased 38% to $491,000 in 2001 from $355,000 in 2000. The increase in expenditures in 2001 was attributable to increased spending on new product development in the geo-location application technology area. Other Income, net Net other income remained constant at $24,000 in the first quarter of 2001 and 2000. Other income includes gains or losses from sales of equipment and other miscellaneous income items. Interest Income and Expense Net interest income decreased to $60,000 in 2001 from $132,000 in 2000. This decrease is attributable to lower average cash balances on hand during the 2001 period, lower prevailing interest rates earned on invested cash, and interest earned during the 2000 period on the Company's note receivable with KSI Inc., which was not outstanding during the comparable 2001 period. Liquidity and Capital Resources The Company's capital requirements have consisted primarily of funding software and hardware research and development, property and equipment requirements, working capital and the Company's operating expenses. The Company historically has funded these requirements through the sale of common stock (including proceeds from the exercise of warrants and options) and from operating profits in certain periods. On March 31, 2001, the Company's cash balance was $5.7 million as compared to $4.5 million on December 31, 2000. The Company's working capital increased to $5.5 million at March 31, 2001 from $5.4 million at December 31, 2000. Net cash provided by operating activities amounted to $1.2 million in Q1 2001, compared to $2.3 million in the comparable 2000 period. The largest factor in the decreased level of cash provided by operations in 2001 compared to 2000 was the $0.7 million in reduced net income in the 2001 period. Additionally, accounts receivable increased by $0.1 million in the 2001 period, compared to a decrease of $0.5 million in the 2000 period, and reduced non-cash charges in the 2001 period accounted for a $0.1 million reduction in operating cash flow compared to the prior year period. Net cash provided by investing activities totaled $8,000 in 2001, compared to cash used in investing activities of $48,000 in 2000. At March 31, 2001, the Company had no significant commitments for capital expenditures. Net cash provided by financing activities was zero in 2001 compared to $1,000 in 2000. The 2000 amount was composed of cash received from stock option exercises. Operating Trends The Company had an operating loss of $50,000 in the first quarter of 2001, compared to earnings of $2.6 million for each of the full years ended December 31, 2000 and 1999. As of March 31, 2001, the Company had an accumulated deficit of $21.8 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. In 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 Page 11

revenue. Through the end of 2000 the results of the Company's restructuring plan showed significant improvement in profitability and cash flow. In the first quarter of 2001, revenue from prepaid phone cards represented 75% of total revenue, and revenue from Blackbird Platform Products represented 25% of the Company's total revenue. While the Company anticipates continued profitability from Blackbird Platform Products in 2001, revenue from Blackbird Platform Products will continue to decline over time. As the industry moves from analog to digital wireless equipment, the need for the Company's Blackbird Platform Products has decreased and will continue to decrease. As anticipated in the Company's strategic plan, the Company currently forecasts that revenue from Blackbird Platform Products will not continue into 2002. Despite the Company's profitability, positive cash flow, and product diversification in 1999 and 2000, 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 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 will 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.

We do not use derivative financial instruments for speculative or trading purposes. We maintain a short-term investment portfolio consisting of interest bearing securities with maturities of less than ninety days. These securities are classified as cash. These securities are interest bearing and thus subject to interest rate risk and will fall in value if market interest rates increase. Because we have the ability to hold our fixed income investments until maturity, we do not expect our operating results or cash flows to be affected to any significant degree by a sudden change in market interest rates on our securities portfolio. We have operated primarily in the United States and all revenues to date have been in U.S. dollars. Accordingly, we do not have material exposure to foreign currency rate fluctuations. We have not entered into any foreign exchange contracts to hedge any exposure to foreign currency rate fluctuations because such exposure is immaterial. Page 12
