Product revenues were $1.4 million in the second quarter of fiscal 2002, a decrease of $1.2 million from the $2.6 million reported in the second quarter of fiscal 2001. Product revenues were $3.0 million for the six month period ended September 30, 2001, a decrease of approximately $4.6 million from the $7.6 million reported in the prior year period. The decreases in the three and six month periods ended September 30, 2001 as compared to the corresponding periods in the prior year were due primarily to a decrease in unit shipments of videoconferencing semiconductor products and media hub systems, offset partially by increased sales of Audacity-T2 semiconductors and increases in average selling prices (ASPs) associated with our videoconferencing semiconductor products. The decrease in product revenues for the six month period ended September 30, 2001 as compared to the prior year was also due to a decrease in sales of video monitoring systems resulting from our exit from this business.

License and other revenues were $2.5 million in the second quarter of fiscal 2002, an increase of approximately $1.2 million over the $1.3 million reported in the second quarter of fiscal 2001. License and other revenues were $4.5 million for the six month period ended September 30, 2001, an increase of approximately $2.4 million over the $2.1 million reported in the prior year period. License and other revenues for the periods reported consist primarily of technology licenses, including royalties earned pursuant to such licenses. However, license and other revenues for the three and six month periods ended September 30, 2000 also included professional service revenues associated with the Canadian operations. No professional service revenues were recognized in the corresponding periods in fiscal 2002 due to the elimination of the professional services organization as part of the restructuring of our Canadian operations in the fourth quarter of fiscal 2001. The negative impact of eliminating professional service revenues in fiscal 2002 was more than offset by improvements in other areas as compared to the prior year including increases in:

• Licenses of our IP telephony technology, e.g., Veracity VoIP software and Audacity-T2 based reference design kits marketed by Netergy Micro;
• SCE license revenue due to the recognition of revenue associated with our license of SCE technology to Lucent;
• Revenue associated with the license of our video monitoring technology to Interlogix in fiscal 2001.

Recognition of the approximately $3.9 million of revenue ascribed to the license of video monitoring technology to Interlogix in fiscal 2001 had been deferred until we satisfied certain remaining obligations in the quarter ended March 31, 2001. Revenue associated with the license is being recognized ratably over the license term which expires in May 2003. The remaining balance in deferred revenue at September 30, 2001 is approximately $2.9 million.

Four customers represented more than 10% of our total revenues for the quarter ended September 30, 2001. These customers represented 17%, 16%, 11% and 10% of our total revenues, respectively. One customer represented 13% of our total revenues for the quarter ended September 30, 2000. Two customers represented 16% and 12% of our total revenues, respectively, for the six month period ended September 30, 2001. No customer represented 10% or more of our total revenues for the six month period ended September 30, 2000.

Cost of Revenues and Gross Profit

The cost of product revenues consists of costs associated with components, semiconductor wafer fabrication, system and semiconductor assembly and testing performed by third-party vendors and direct and indirect costs associated with purchasing, scheduling and quality assurance. Gross profit from product revenues decreased to $1.0 million in the second quarter of fiscal 2002 from $1.3 million for the quarter ended September 30, 2000 due to a decrease in product revenues offset by an increase in product gross margins from 52% to 72%. The increase in product gross margins is due to an increase in average selling prices (ASPs) on our videoconferencing semiconductors and a decrease in manufacturing overhead costs as a result of our cost reduction efforts. Gross profit from product revenues decreased to approx. $1.6 million for the six month period ended September 30, 2001 from $4.8 million during the corresponding period of the prior year to a decrease in product revenues and a decrease in product gross margins from 63% to 55%. The decrease in product gross margins is due primarily to inventory reserves associated with our media hub products that we recorded in the first quarter of fiscal 2002, offset by an increase in average selling prices (ASPs) on our videoconferencing semiconductors.

The cost of license and other revenues for the periods presented consist principally of royalties associated with technology sublicensed from third parties and certain costs associated with providing maintenance services. The cost of license and other revenues for the three and six month periods ended September 30, 2000 also included costs associated with the U|Force professional services organization. No such costs were incurred in the corresponding periods in fiscal 2002 due to the elimination of the U|Force professional services organization as part of the restructuring of our Canadian operations in the fourth quarter of fiscal 2001. Due to the low gross margins attributable to professional service revenues, the elimination of the professional services organization had a significant impact on gross margins associated with overall license and other revenues in fiscal 2002. Gross margin increased from 61% during the three months ended September 30, 2000 to 99% in the quarter ended September 30, 2001. Gross margin increased from 74% during the six months ended September 30, 2000 to 98% in the corresponding period in the current fiscal year.

Research and Development Expenses

Research and development expenses consist primarily of personnel, system prototype design and fabrication, mask, prototype wafer and equipment costs necessary for us to conduct our development efforts. Research and development costs, including software development costs, are expensed as incurred. Research and development expenses decreased by $2.1 million in the second quarter of fiscal 2002 as compared to the second quarter of fiscal 2001, and decreased by approximately $2.4 million in the first six months of fiscal 2002 as compared to the first six months of fiscal 2001. The significant decreases in research and development expenses for the three and six month periods ended September 30, 2001 as compared to the comparable periods in the prior year are due to the following:

• The elimination of our Canadian operations in the fourth quarter of fiscal 2001;
• Reductions in headcount;
• Lower consulting expenses associated with development of the graphical user interface for Centile's hosted iPBX product; and
• Our overall efforts to reduce discretionary operating costs.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of personnel and related overhead costs for sales, marketing, finance, human resources and general management. Such costs also include sales commissions, trade show, advertising and other marketing and promotional expenses. Selling, general and administrative expenses decreased by $2.3 million in the second quarter of fiscal 2002 as compared the same period in the prior year and decreased by approximately $3.1 million in the first six months of fiscal 2002 as compared to the first six months of fiscal 2001. The decreases in selling, general and administrative expenses during the three and six month periods ended September 30, 2001 as compared to the comparable periods in the prior year are primarily attributable to:

• The elimination of our Canadian operations in the fourth quarter of fiscal 2001;

• Reductions in headcount; and

• Lower legal, travel, corporate marketing, public relations and trade show expenditures resulting from our efforts to reduce discretionary operating costs.

In-Process Research and Development and Amortization of Intangibles

In the second quarter of fiscal 2001 we incurred an in- process research and development charge of $4.6 million related to the acquisition of U|Force.

In conjunction with the acquisition of Odisei S.A. in May 1999, we recorded intangible assets related to goodwill and workforce that are being amortized on a straight-line basis over five and three years, respectively. Approximately $190,000 of such amortization was charged to operations during each of the two three-month periods ending September 30, 2001 and 2000. An additional $3.4 million was charged to operating expenses during the second quarter of fiscal 2001 related to the amortization of intangible assets acquired as a result of the acquisition of U|Force. Amortization of intangible assets totaled $382,000 and $3.8 million in the six month periods ended September 30, 2001 and 2000, respectively. This decrease in amortization of intangibles was primarily due to the write off of U|Force intangible assets during the fourth quarter of fiscal 2001.

See the financial statements in our Report on Form 10-K for the fiscal year ended March 31, 2001 for further explanation of the U|Force transaction.

Other Income, Net

In the second quarters of fiscal 2002 and 2001, other income, net, was $112,000 and $918,000, respectively. During the six month periods ending September 30, 2001 and 2000, other income, net, was $456,000 and $1.9 million, respectively. During fiscal 1996, we acquired an equity position in a privately held company. We realized a gain of $225,000 in the quarter ended June 30, 2000 resulting from the sale of this investment. Apart from the realized gain on the sale of an investment as noted above, other income consists primarily of interest income earned on our cash and cash equivalents. Interest income decreased significantly in the first two quarters of fiscal 2002 as compared to the corresponding periods of the prior fiscal year due primarily to significantly lower average cash and cash equivalent balances combined with lower interest rates.

Interest Expense

Interest expense for the three and six month periods ended September 30, 2001 and 2000, respectively, consists mainly of charges associated with the convertible subordinated debentures issued in December 1999, as well as the amortization of the related debt discount and debt issuance costs. In addition, approximately $32,000 of interest expense was incurred in the quarter ended September 30, 2000 resulting from lines of credit assumed as part of the U|Force acquisition.

Provision for Income Taxes

There were no tax provisions recorded in the second quarters of fiscal 2002 and 2001, or during the six month period ended September 30, 2001, due to net losses incurred. The tax provision of $12,000 reported for the six month period ended September 30, 2000 represents certain foreign taxes.

Recent Accounting Pronouncements

In June 1998, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Financial Instruments and for Hedging Activities." SFAS No. 133, as amended by SFAS No. 138, provides a comprehensive and consistent standard for the recognition and measurement of derivatives and hedging activities. The Company adopted SFAS No. 133, beginning April 1, 2001, and it did not have a material impact on the Company's results of operations or financial condition.

In July 2001, the FASB issued SFAS No. 141, "Business Combinations," and SFAS No. 142, "Goodwill and Other Intangible Assets." These statements make significant changes to the accounting for business combinations, goodwill, and intangible assets and become effective for fiscal years beginning after December 15, 2001. The new rules also require business combinations initiated after June 30, 2001 to be accounted for using the purchase method and goodwill recorded after June 30, 2001 will not be amortized. Goodwill existing at June 30, 2001 will continue to be amortized through the end of fiscal 2002. Beginning in the first quarter of fiscal 2003, goodwill will no longer be amortized but will be subject to annual impairment tests. All other intangible assets will continue to be amortized over their estimated useful lives. Through the end of fiscal 2002, the Company will test goodwill for impairment using the current method, which uses an undiscounted cash flow test. During fiscal 2003, the Company will begin to test goodwill for impairment under the new rules, applying a fair-value based test. Based on acquisitions completed as of June 30, 2001, application of the goodwill non-amortization provisions of these rules is expected to result in a decrease in operating expenses of approximately $697,000 for fiscal 2003.

On October 3, 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets". SFAS 144 supercedes SFAS 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." SFAS 144 applies to all long-lived assets (including discontinued operations) and consequently amends Accounting Principles Board Opinion No. 30. SFAS 144 develops one accounting model for long-lived assets that are to be disposed of by sale. SFAS 144 requires that long-lived assets that are to be disposed of by sale be measured at the lower of book value or fair value less cost to sell. Additionally, SFAS 144 expands the scope of discontinued operations to include all components of an entity with operations that (1) can be distinguished from the rest of the entity and (2) will be eliminated from the ongoing operations of the entity in a disposal transaction. SFAS 144 is effective for the Company for all financial statements issued in fiscal 2003.

Liquidity and Capital Resources

As of September 30, 2001, we had cash and cash equivalents totaling $19.0 million, representing a decrease of approximately $5.1 million from March 31, 2001. We currently have no bank borrowing arrangements.

Cash used in operations of approximately $5.2 million in the first six months of fiscal 2002 is primarily attributable to the net loss of $6.4 million, a $594,000 decrease in accounts payable, a $490,000 decrease in accrued compensation, and a $2.0 million decrease in deferred revenue. This was offset by a decrease in accounts receivable of $1.7 million, a $489,000 decrease in other current assets, and non-cash items, including depreciation and amortization of $2.2 million. Cash used in operations of approximately $10.1 million in the first six months of fiscal 2001 is primarily attributable to the net loss of $18.2 million, increases in prepaid expenses and other assets of approximately $3.1 million, decreases in accounts payable and deferred revenue of $926,000 and $349,000, and a net gain resulting from the sale of an investment of $225,000. Cash used in operations was partially offset by an increase in other accrued liabilities of $601,000 and non-cash items, including depreciation and amortization of $5.2 million, stock compensation charges of $625,000 and a charge for purchased in-process research and development of $4.6 million.

Cash used in investing activities in the six months ended September 30, 2001 is attributable to capital expenditures of $123,000 offset by proceeds from the sale of equipment of $55,000. Cash provided by investing activities in the six months ended September 30, 2000 is primarily attributable to net proceeds from the sale of assets and the license of technology associated with our video monitoring business of $5.2 million and proceeds from the sale of a non-marketable equity investment of $225,000, offset by capital expenditures of $2.5 million and net cash paid of $493,000 related to the acquisition of U|Force.

Cash provided by financing activities during the first two quarters of fiscal 2002 consisted primarily of proceeds resulting from the sale of the our common stock to employees through our employee stock purchase and stock option plans. Cash provided by financing activities in the six month period ended September 30, 2000 consisted primarily of net proceeds from the repayment of stockholders' notes receivable and net proceeds from sales of our common stock to employees through our employee stock purchase and stock option plans, offset by the repayment of certain debt obligations.

As of September 30, 2001, our principal commitments consisted of obligations outstanding under non-cancelable operating leases.

In December 1999, the Company issued $7.5 million of 4% Series A and Series B convertible subordinated debentures (the Debentures). The Debentures mature in December 2002 unless converted earlier. Repayment of the Debentures may be accelerated by the lenders under certain circumstances, including the suspension of trading or failure of the Company's common stock to be listed on the Nasdaq National Market, the New York Stock Exchange, or the American Stock Exchange for a period of 5 consecutive trading days or 10 trading days in a 365 day period. In such a case the Debentures are repayable at up to 110% of their face amount.

Although we believe that our current cash and cash equivalents will satisfy our expected working capital and capital expenditure requirements through at least the next twelve months, our business may change in ways we do not currently anticipate requiring us to raise additional funds to support our operations earlier than otherwise expected. In addition, we anticipate that we may require additional funds to support our business in fiscal 2003. We may not be able to obtain additional financing as needed on acceptable terms, or at all, which may require us to further reduce our operating costs and other expenditures by making additional reductions in personnel and capital expenditures. Alternatively, or in addition to such potential measures, we may elect to implement other cost reduction actions as we may determine are necessary and in our best interests, including the possible sale or cessation of some or all of our business segments. Any such actions undertaken might limit our opportunities to realize plans for revenue growth and we might not be able to reduce our costs in amounts sufficient to achieve break- even or profitable operations.

Our financial market risk consists primarily of risks associated with international operations and related foreign currencies. We derive a significant portion of our revenues from customers in Europe and Asia. In order to reduce the risk from fluctuation in foreign exchange rates, the vast majority of our sales are denominated in U.S. dollars. In addition, all of our arrangements with our semiconductor foundry and assembly vendors are denominated in U.S. dollars. We have foreign subsidiaries and are exposed to market risk from changes in exchange rates. We have not entered into any currency hedging activities. To date, our exposure to exchange rate volatility has not been significant; however, there can be no assurance that there will not be a material impact in the future.

We invest our surplus cash and cash equivalents in money market funds with variable interest rates, and, accordingly, fluctuations in interest rates do not have an impact on the fair values of such investments.

As of September 30, 2001, we had approximately $19.0 million in cash and cash equivalents. We believe that our current cash and cash equivalents, and cash generated from operations, if any, will satisfy our expected working capital and capital expenditure requirements through at least the next twelve months. We may, however, need additional working capital shortly thereafter. Accordingly, we may seek additional financing at some point during the next twelve months in order to meet our cash requirements in fiscal 2003. We may also seek to explore business opportunities, including acquiring or investing in complementary businesses or products that will require additional capital from equity or debt sources. Additionally, the development and marketing of new products could require a significant commitment of resources, which could in turn require us to obtain additional financing earlier than otherwise expected. We may not be able to obtain additional financing as needed on acceptable terms, or at all, which may require us to further reduce our operating costs and other expenditures, including additional reductions of personnel and suspension of salary increases and capital expenditures. Alternatively, or in addition to such potential measures, we may elect to implement other cost reduction actions as we may determine are necessary and in our best interests, including the possible sale or cessation of certain of our business segments. Any such actions undertaken might limit our opportunities to realize plans for revenue growth and we might not be able to reduce our costs in amounts sufficient to achieve break-even or profitable operations. If we issue additional equity or convertible debt securities to raise funds, the ownership percentage of our existing stockholders would be reduced. New investors may demand rights, preferences or privileges senior to those of existing holders of our common stock.

We recorded an operating loss of approximately $6.2 million in the six months ended September 30, 2001 and we ended the period with an accumulated deficit of $134.6 million. In addition, we recorded operating losses of $74.5 million and $27.1 million for the fiscal years ended March 31, 2001 and 2000, respectively. We expect that the Company, as well as its subsidiaries individually, will continue to incur operating losses for the foreseeable future, and such losses may be substantial. We will need to generate significant revenue growth to achieve profitability. Given our history of fluctuating revenues and operating losses, we cannot be certain that we will be able to achieve profitability on either a quarterly or annual basis.

Additionally, under the terms of our convertible debt financing, we are required to maintain the listing of our common stock on either the Nasdaq National Market, the New York Stock Exchange, or the American Stock Exchange. Repayment of the convertible debt may be accelerated by the holders upon the suspension of trading or failure of our common stock to be listed for a period of 5 consecutive trading days or 10 trading days in a 365 day period. In such a case, outstanding convertible debt is repayable at up to 110% of the face amount.

We believe that our business and future profitability will be largely dependent on widespread market acceptance of our internet protocol (IP) telephony technology and products. Our videoconferencing semiconductor business has not provided, nor is it expected to provide, sufficient revenues to profitably operate our business. To date, we have not generated significant revenue from the sale of our IP telephony products. If we are not able to generate significant revenues selling into the IP telephony market, our business and operating results would be seriously harmed.

Success of our IP telephony product strategy assumes that there will be future demand for IP telephony systems and services. In order for the IP telephony market to continue to grow, several things need to occur. Telephone service providers must continue to invest in the deployment of high speed broadband networks to residential and commercial customers. IP networks must improve quality of service for real-time communications, managing effects such as packet jitter, packet loss, and unreliable bandwidth, so that toll- quality service can be provided. IP telephony equipment must achieve the 99.999% reliability that users of the public switched telephone network (PSTN) have come to expect from their telephone service. IP telephony service providers must offer cost and feature benefits to their customers that are sufficient to cause the customers to switch away from traditional telephony service providers. If any or all of these factors fail to occur, our business may not grow.

Our historical operating results have fluctuated significantly and will likely continue to fluctuate in the future, and a decline in our operating results could cause our stock price to fall. On an annual and a quarterly basis, there are a number of factors that may affect our operating results, many of which are outside our control. These include, but are not limited to:

• changes in market demand;
• the timing of customer orders;
• competitive market conditions;
• lengthy sales cycles and/or regulatory approval cycles;
• new product introductions by us or our competitors;
• market acceptance of new or existing products;
• the cost and availability of components;
• the mix of our customer base and sales channels;
• the mix of products sold;
• the management of inventory;
• the level of international sales;
• continued compliance with industry standards; and
• general economic conditions.

Our gross margin is affected by a number of factors including, product mix, the recognition of license and other revenues for which there may be little or no corresponding cost of revenues, product pricing, the allocation between international and domestic sales, the percentage of direct sales and sales to resellers, and manufacturing and component costs. The markets for our products are characterized by falling average selling prices. We expect that, as a result of competitive pressures and other factors, gross profit as a percentage of revenue for our videoconferencing semiconductor products will continue to decrease for the foreseeable future. Average selling prices (ASPs) realized to date for our IP telephony semiconductors have been lower than those historically attained for our videoconferencing semiconductor products resulting in lower gross margins. In the likely event that we encounter significant price competition in the markets for our products, we could be at a significant disadvantage compared to our competitors, many of whom have substantially greater resources, and therefore may be better able to withstand an extended period of downward pricing pressure.

Variations in timing of sales may cause significant fluctuations in future operating results. In addition, because a significant portion of our business may be derived from orders placed by a limited number of large customers, including OEM customers, the timing of such orders can also cause significant fluctuations in our operating results. Anticipated orders from customers may fail to materialize. Delivery schedules may be deferred or canceled for a number of reasons, including changes in specific customer requirements or international economic conditions. The adverse impact of a shortfall in our revenues may be magnified by our inability to adjust spending to compensate for such shortfall. Announcements by our competitors or us of new products and technologies could cause customers to defer purchases of our existing products, which would also have a material adverse effect on our business and operating results.

As a result of these and other factors, it is likely that in some or all future periods our operating results will be below the expectations of securities analysts or investors, which would likely result in a significant reduction in the market price of our common stock.

Our products have lead times of up to several months, and are built to forecasts that are necessarily imprecise. Because of our practice of building our products to necessarily imprecise forecasts, it is likely that, from time to time, we will have either excess or insufficient product inventory. Excess inventory levels would subject us to the risk of inventory obsolescence and the risk that our selling prices may drop below our inventory costs, while insufficient levels of inventory may negatively affect relations with customers. Any of these factors could have a material adverse effect on our business, operating results, and financial condition.

Historically, a significant portion of our sales has been to relatively few customers, although the composition of these customers has varied. Revenues from our ten largest customers for the quarters ended September 30, 2001 and 2000, respectively, accounted for approximately 86% and 51% of total revenues. Revenues from our ten largest customers for the fiscal years ended March 31, 2001 and 2000 accounted for approximately 48% and 35%, respectively, of total revenues. Substantially all of our product sales have been made, and are expected to continue to be made, on a purchase order basis. None of our customers has entered into a long-term agreement requiring it to purchase our products. In the future, we will need to gain purchase orders for our products to earn additional revenue. Further, substantially all of our license and other revenues are nonrecurring.

IP telephony is an emerging market that is characterized by rapid changes in customer requirements, frequent introductions of new and enhanced products, and continuing and rapid technological advancement. To compete successfully in this emerging market, we must continue to design, develop, manufacture, and sell new and enhanced semiconductor and IP telephony software products and services that provide increasingly higher levels of performance and reliability at lower cost. These new and enhanced products must take advantage of technological advancements and changes, and respond to new customer requirements. Our success in designing, developing, manufacturing, and selling such products and services will depend on a variety of factors, including:

• the identification of market demand for new products;
• product and feature selection;
• timely implementation of product design and development;
• product performance;
• cost-effectiveness of products under development;
• effective manufacturing processes; and
• success of promotional efforts.

Additionally, we may also be required to collaborate with third parties to develop our products and may not be able to do so on a timely and cost-effective basis, if at all. We have in the past experienced delays in the development of new products and the enhancement of existing products, and such delays will likely occur in the future. If we are unable, due to resource constraints or technological or other reasons, to develop and introduce new or enhanced products in a timely manner, if such new or enhanced products do not achieve sufficient market acceptance, or if such new product introductions decrease demand for existing products, our operating results would decline and our business would not grow.

Our IP telephony software products, including our hosted iPBX, SCE and unified messaging products, have lengthy sales cycles, and we may incur substantial sales and marketing expenses and expend significant management effort without making a sale. A customer's decision to purchase our products often involves a significant commitment of its resources and a lengthy product evaluation and qualification process. In addition, the length of our sales cycles will vary depending on the type of customer to whom we are selling and the product being sold. Even after making the decision to purchase our products, our customers may deploy our products slowly. Timing of deployment can vary widely and will depend on various factors, including:

• the size of the network deployment;
• the complexity of our customers' network environments;
• our customers' skill sets;
• the hardware and software configuration and customization necessary to deploy our products; and
• our customers' ability to finance their purchase of our products.

As a result, it is difficult for us to predict the quarter in which our customers may purchase our products, and our revenue and operating results may vary significantly from quarter to quarter.

Many of the potential customers for our hosted iPBX and unified messaging products have requested that our products be designed to interoperate with their existing networks, each of which may have different specifications and use multiple standards. Our customers' networks may contain multiple generations of products from different vendors that have been added over time as their networks have grown and evolved. Our products must interoperate with these products as well as with future products in order to meet our customers' requirements. In some cases, we may be required to modify our product designs to achieve a sale, which may result in a longer sales cycle, increased research and development expense, and reduced operating margins. If our products do not interoperate with existing equipment or software in our customers' networks, installations could be delayed, orders for our products could be canceled or our products could be returned. This could harm our business, financial condition, and results of operations.

Our hosted iPBX solution must successfully integrate with products from other vendors, such as traditional telephone systems. As a result, when problems occur in a network, it may be difficult to identify the source of the problem. The occurrence of hardware and software errors, whether caused by our hosted iPBX solution or another vendor's products, may result in the delay or loss of market acceptance of our products and any necessary revisions may force us to incur significant expenses. The occurrence of some of these types of problems may seriously harm our business, financial condition and results of operations.

We expect our competitors to continue to improve the performance of their current products and introduce new products or new technologies. If our competitors successfully introduce new products or enhance their existing products, this could reduce the sales or market acceptance of our products and services, increase price competition or make our products obsolete. To be competitive, we must continue to invest significant resources in research and development, sales and marketing, and customer support. We may not have sufficient resources to make these investments or to make the technological advances necessary to be competitive, which in turn will cause our business to suffer.

In addition, our focus on developing a range of technology products, including semiconductors and related embedded software, hosted iPBX solutions, and service creation software, places a significant strain on our research and development resources. Competitors that focus on one aspect of technology, such as software or semiconductors, may have a considerable advantage over us. In addition, many of our current and potential competitors have longer operating histories, are substantially larger, and have greater financial, manufacturing, marketing, technical, and other resources. For example, certain competitors in the market for our semiconductor products maintain their own semiconductor foundries and may therefore benefit from certain capacity, cost and technical advantages. Many also have greater name recognition and a larger installed base of products than us. Competition in our markets may result in significant price reductions. As a result of their greater resources, many current and potential competitors may be better able than us to initiate and withstand significant price competition or downturns in the economy. There can be no assurance that we will be able to continue to compete effectively, and any failure to do so would harm our business, operating results, and financial condition.

We are entering into new market areas and our success is partly dependent on our ability to forge new marketing and engineering partnerships. IP telephony communication systems are extremely complex and no single company possesses all the required technology components needed to build a complete end to end solution. We will likely need to enter into partnerships to augment our development programs and to assist us in marketing complete solutions to our targeted customers. We may not be able to develop such partnerships in the course of our product development. Even if we do establish the necessary partnerships, we may not be able to adequately capitalize on these partnerships to aid in the success of our business.

There has been substantial litigation in the semiconductor, electronics, and related industries regarding intellectual property rights, and from time to time third parties may claim infringement by us of their intellectual property rights. Our broad range of technology, including systems, digital and analog circuits, software, and semiconductors, increases the likelihood that third parties may claim infringement by us of their intellectual property rights. If we were found to be infringing on the intellectual property rights of any third party, we could be subject to liabilities for such infringement, which could be material. We could also be required to refrain from using, manufacturing or selling certain products or using certain processes, either of which could have a material adverse effect on our business and operating results. From time to time, we have received, and may continue to receive in the future, notices of claims of infringement, misappropriation or misuse of other parties' proprietary rights. There can be no assurance that we will prevail in these discussions and actions or that other actions alleging infringement by the Company of third-party patents will not be asserted or prosecuted against the Company.

We rely on certain technology, including hardware and software licensed from third parties. The loss of, or inability to maintain, existing licenses could have a material adverse effect on our business and operating results. In addition, we may be required to license technology from third parties in the future to develop new products or product enhancements. Third-party licenses may not be available to us on commercially reasonable terms, if at all. Our inability to obtain third-party licenses required to develop new products and product enhancements could require us to obtain substitute technology of lower quality or performance standards or at a greater cost, any of which could seriously harm our business, financial condition and operating results.

The market for the services provided by telecommunication service providers who compete against traditional telephone companies has only begun to emerge, and many of these service providers are still building their infrastructure and rolling out their services. These telecommunication service providers require substantial capital for the development, construction, and expansion of their networks and the introduction of their services. Financing may not be available to emerging telecommunication service providers on favorable terms, if at all. The inability of our current or potential emerging telecommunication service provider customers to acquire and keep customers, to successfully raise needed funds, or to respond to any other trends such as price reductions for their services or diminished demand for telecommunication services generally, could adversely affect their operating results or cause them to reduce their capital spending programs. If our current or potential customers are forced to defer or curtail their capital spending programs, sales of our hosted iPBX, SCE and unified messaging products to those telecommunication service providers may be adversely affected, which would negatively impact our business, financial condition, and results of operations. In addition, many of the industries in which telecommunication service providers operate have recently experienced consolidation. The loss of one or more of our current or potential telecommunication service provider customers, through industry consolidation or otherwise, could reduce or eliminate our sales to such a customer and consequently harm our business, financial condition, and results of operations.

Circuit-switched telephony networks feature very high reliability, with a guaranteed quality of service. The common standard for reliability of carrier-grade real-time voice communications is 99.999%, meaning that the network can be down for only a few minutes per year. In addition, such networks have imperceptible delay and consistently satisfactory audio quality. Emerging broadband IP networks, such as LANs, WANs, and the Internet, or emerging last mile technologies such as cable, DSL, and wireless local loop, may not be used for telephony unless such networks and technologies can provide reliability and quality consistent with these standards.

In addition to reliability and quality standards, the market acceptance of telephony over broadband IP networks is dependent upon the adoption of industry standards so that products from multiple manufacturers are able to communicate with each other. IP telephony products rely heavily on standards such as H.323, SIP, SGCP, MGCP, H.GCP, and Megaco to interoperate with other vendors' equipment. There is currently a lack of agreement among industry leaders about which standard should be used for a particular application, and about the definition of the standards themselves. We also must comply with certain rules and regulations of the Federal Communications Commission (FCC) regarding electromagnetic radiation and safety standards established by Underwriters Laboratories as well as similar regulations and standards applicable in other countries. Standards are continuously being modified and replaced. As standards evolve, we may be required to modify our existing products or develop and support new versions of our products. The failure of our products to comply, or delays in compliance, with various existing and evolving industry standards could delay or interrupt volume production of our IP telephony products, which would have a material adverse effect on our business, financial condition and operating results.

At present there are few laws or regulations that specifically address access to or commerce on the Internet, including IP telephony. We are unable to predict the impact, if any, that future legislation, legal decisions or regulations concerning the Internet may have on our business, financial condition, and results of operations. Regulation may be targeted towards, among other things, assessing access or settlement charges, imposing tariffs or imposing regulations based on encryption concerns or the characteristics and quality of products and services, any of which could restrict our business or increase our cost of doing business. The increasing growth of the broadband IP telephony market and popularity of broadband IP telephony products and services heighten the risk that governments will seek to regulate broadband IP telephony and the Internet. In addition, large, established telecommunication companies may devote substantial lobbying efforts to influence the regulation of the broadband IP telephony market, which may be contrary to our interests.

We continuously evaluate the benefits, on an integrated circuit, product-by-product basis, of migrating to smaller geometry process technologies in order to reduce costs related to the development and production of our semiconductors. We believe that the transition of our products to increasingly smaller geometries will be important for us to remain competitive. We have in the past experienced difficulty in migrating to new manufacturing processes, which has resulted and could continue to result in reduced yields, delays in product deliveries, and increased expense levels. Moreover, we are dependent on relationships with our foundries and their partners to migrate to smaller geometry processes successfully. If any such transition is substantially delayed or inefficiently implemented, we may experience delays in product introductions and incur increased expenses. As smaller geometry processes become more prevalent, we expect to integrate greater levels of functionality, as well as customer and third party intellectual property, into our products. We cannot predict whether higher levels of design integration or the use of third-party intellectual property will adversely affect our ability to deliver new integrated products on a timely basis, or at all.

We outsource the manufacturing of our semiconductor products to independent foundries. Our primary semiconductor manufacturer is Taiwan Semiconductor Manufacturing Corporation (TSMC). While TSMC has been a valuable and capable supplier, there are no assurances or supply contracts guaranteeing that they will continue to supply us with our required wafer supply. Furthermore, Taiwan is always subject to geological or geopolitical disturbances that could instantly cut off such supply. We also rely on other third party manufacturers for packaging and testing of our semiconductors.

We do not have long-term purchase agreements with our subcontract manufacturers or our component suppliers. There can be no assurance that our subcontract manufacturers will be able or willing to reliably manufacture our products, in volumes, on a cost effective basis or in a timely manner. For our semiconductor products, the time to port our technology to another foundry, the time to qualify the new versions of product, and the cost of this effort as well as the tooling associated with wafer production would have a material adverse effect on our business, operating results, and financial condition.

Products as complex as those we offer frequently contain errors, defects, and functional limitations when first introduced or as new versions are released. We have in the past experienced such errors, defects or functional limitations. We sell products into markets that are extremely demanding of robust, reliable, fully functional products. Therefore, delivery of products with production defects or reliability, quality or compatibility problems could significantly delay or hinder market acceptance of such products, which could damage our credibility with our customers and adversely affect our ability to retain our existing customers and to attract new customers. Moreover, such errors, defects or functional limitations could cause problems, interruptions, delays or a cessation of sales to our customers. Alleviating such problems may require significant expenditures of capital and resources by us. Despite our testing, our suppliers or our customers may find errors, defects or functional limitations in new products after commencement of commercial production. This could result in additional development costs, loss of, or delays in, market acceptance, diversion of technical and other resources from our other development efforts, product repair or replacement costs, claims by our customers or others against us, or the loss of credibility with our current and prospective customers.

Sales to customers outside of North America represented 64% of total revenue during both the three and six month periods ended September 30, 2001. The table below shows the percentage of total revenue received from customers in the different regions.

Substantially all of our current semiconductor and system- level products are, and substantially all of our future products will be, manufactured, assembled, and tested by independent third parties in foreign countries. International sales and manufacturing are subject to a number of risks, including general economic conditions in regions such as Asia, changes in foreign government regulations and telecommunication standards, export license requirements, tariffs and taxes, other trade barriers, fluctuations in currency exchange rates, difficulty in collecting accounts receivable, and difficulty in staffing and managing foreign operations. We are also subject to geopolitical risks, such as political, social, and economic instability, potential hostilities, and changes in diplomatic and trade relationships, in connection with our international operations. A significant decline in demand from foreign markets could have a material adverse effect on our business, operating results, and financial condition.

The development and marketing of our IP telephony products will continue to place a significant strain on our limited personnel, management, and other resources. While the pace of economic growth in the San Francisco Bay Area (where our corporate headquarters are located) has slowed in recent months, competition for highly skilled engineering, sales, marketing, and support personnel has remained strong. Any failure to retain qualified personnel could adversely affect our financial results and impair our growth. We currently do not maintain key person life insurance policies on any of our employees.

On April 6, 2001, we, along with Sun Microsystems, Inc., Netscape Communications Canada Inc., Burntsand Inc., and Intraware Canada Inc., were sued by Milinx Business Services, Inc. and Milinx Business Group Inc. (collectively, Milinx) in the Supreme Court of British Columbia, Canada (the Court). Milinx has alleged that we failed to perform certain contractual obligations and knowingly misrepresented the capabilities of our products. The lawsuit seeks general, special, and aggravated damages totaling in excess of $65 million Canadian dollars plus interest, costs, and any other relief which the Court may choose to provide. We believe we have valid defenses against the claims alleged by Milinx and intend to continue our defense this lawsuit vigorously. However, due to the nature of litigation and because the lawsuit is in the very early pre-discovery stages, we cannot determine the possible loss, if any, that may ultimately be incurred either in the context of a trial or a negotiated settlement. Should we not prevail in any such litigation, our operating results and financial condition could be adversely impacted.

The market price of the shares of our common stock has been and is likely to be highly volatile. It may be significantly affected by factors such as:

• actual or anticipated fluctuations in our operating results;
• announcements of technical innovations;
• loss of key personnel;
• new products or new contracts by us, our competitors or their customers; and

• developments with respect to patents or proprietary rights, general market conditions, changes in financial estimates by securities analysts, and other factors which could be unrelated to, or outside our control.

The stock market has from time to time experienced significant price and volume fluctuations that have particularly affected the market prices for the common stocks of technology companies and that have often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the market price of our common stock. In the past, following periods of volatility in the market price of a company's securities, securities class action litigation has often been initiated against the issuing company. If our stock price is volatile, we may also be subject to such litigation. Such litigation could result in substantial costs and a diversion of management's attention and resources, which would disrupt business and could cause a decline in our operating results. Any settlement or adverse determination in such litigation would also subject us to significant liability.

Our corporate headquarters is located in the San Francisco Bay area of Northern California, a region known for seismic activity. A significant natural disaster, such as an earthquake, could have a material adverse impact on our business, operating results, and financial condition.

On April 6, 2001, the Company, along with Sun Microsystems, Inc., Netscape Communications Canada Inc., Burntsand Inc., and Intraware Canada Inc., was sued by Milinx Business Services, Inc. and Milinx Business Group Inc. (collectively, Milinx) in the Supreme Court of British Columbia, Canada (the Court). Milinx has alleged that the Company failed to perform certain contractual obligations and knowingly misrepresented the capabilities of its products. The lawsuit seeks general, special, and aggravated damages totaling in excess of $65 million Canadian dollars plus interest, costs, and any other relief which the Court may choose to provide. Management believes that the Company has valid defenses against the claims alleged by Milinx and intends to continue its vigorous defense of this lawsuit. However, due to the nature of litigation and because the lawsuit is in the pre-discovery stages, the Company cannot determine the possible loss, if any, that may ultimately be incurred either in the context of a trial or a negotiated settlement. Should the Company not prevail in the litigation, its operating results and financial condition would be adversely impacted.

The Company is also involved in various other legal claims and litigation that have arisen in the normal course of the Company's operations. While the results of such claims and litigation cannot be predicted with certainty, the Company believes that the final outcome of such matters will not have a significant adverse effect on the Company's financial position or results of operations. However, should the Company not prevail in any such litigation, its operating results and financial position could be adversely impacted.

Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
