Industry Background
Increasing Commercial and Residential Demand for High-Speed Internet Access Broadband Services
In recent years, there has been a dramaticsignificant increase in demand by businesses and consumers for high-speed data access to the Internet and to private corporate networks. This demand is being driven by the growth in users who are accessing networks for a variety of applications, including communications via the Internet and corporate intranets, electronic commerce, and telecommuting. This growth is projectedin data applications has created a need for more broadband transmission bandwidth and for intelligent systems to continuemanage this bandwidth across the multiple applications that often have to increase rapidly over the next several years. Ascompete for access to this bandwidth. In addition to an example of theincreasing demand for broadband data services, there has been substantial consumer demand for advanced digital-based entertainment systems and services. The industry has seen rapid growth in high-speed access, the Vertical Systems Group has projected that totaldevices such as MP-3 and DVD players and in services such as digital subscriber line, or DSL, connections in the United States will increase from 560 thousand in 1999 to over 7.7 million in 2003. Vertical Systems Group also projected that worldwide DSL connections would grow from 637 thousand in 1999 to over 16 million in 2003. 1 cable television service and digital broadcast television service via satellite.
To meet this increasing need for high-speed access, telecommunicationsbroadband video and data services, service providers have significantly upgraded both backbone and local networks with broadband fiber optic facilities and high-speed switches, routers, and multiplexers. In somemany cases, these service providers are bringingextending fiber optic links all the way to residential neighborhoods or to the basements of commercial officemulti-tenant buildings. In addition, other service providers are building wireless broadband access networks using recently available radio spectrum, or are using hybrid fiber coaxial cable networks that are traditionally used to provide cable TV service. Service providers may also use the copper-based infrastructure of an incumbent local exchange carrier, or ILEC, or a government controlled post, telephone and telegraph company, or PTT, to offer DSL-based services. These new networks offer speeds more than 20 times faster than today's 56 kbps dial-up modems. Although service providers are bringing broadband facilities closer to residential and commercial end users, they remain challenged by the cost and logistics associated with extending this bandwidth all the way to Internet devices or digital set-top boxes in a consumer'sconsumer’s home or to the local area network, or LAN, of a small business office. These challenges are particularly acute in MTU complexes where the end-user typically does not directly own the network infrastructure in place, andfor telephony-based service providers where the majority of the existing “last mile” infrastructure tends to be the copper wires being used to provide existing telephone service.
Worldwide Telecommunications Deregulation and New Technology Spawns Competition for Bundled Services
An open regulatory framework for telecom services and advances in broadband technology have led to cable television companies offering voice services, satellite companies offering asymmetric digital subscriber line, or ADSL-based high-speed Internet access, and telephone companies offering high-speed Internet access and video services. By bundling multiple voice, video, and data services into a single service package, leading-edge service providers reduce their infrastructure, marketing and sales cost per revenue dollar, while increasing the retention rate and absolute revenue of their customers. Recent developments by cable-based multi-system operators to offer voice and data services as an add-on package to television service will motivate the ILECs to respond with a bundled offering of voice, video, and data services. If the ILECs do not respond, they may be left with a very underutilized and expensive network as their voice and data customers migrate to competitive offerings. Further, recent technology advances in delivering high-speed gigabit-per-second signals over coaxial networks and in delivering two-way broadband services via satellite will continue to put pressure on these telephony-based service providers to also offer an advanced bundle of broadband services.
Neighborhood Dwelling Unit (NDU) Market Characteristics
The MTUNDU market can be separated into two markets: residential and commercial. The residential MTU market, also known asis generally characterized by a concentrated collection of single-family homes within a radius of approximately a half-mile. In the multi-dwelling unit, or MDU, market, consists primarily of apartments, hotels, and university dormitories. Data from the U.S. Census Bureau indicates that the domestic apartment market totals over 21 million individual tenant units, with 9 millionUnited States, many of these unitsneighborhoods are served by neighborhood digital loop carrier systems, or DLCs, used by the ILEC to provide narrowband voice and data services. It is estimated that over 30% of homes in the United States are served from DLCs for basic telephone service.

2


In many cases, DLCs are connected to the ILEC’s local central office by a broadband fiber facility with capacity to support new broadband services in addition to the narrowband telephone services being locatedprovided today. Further, recent advances in buildingstransmission technology have led to very high speed digital subscriber line, or complexes of 50VDSL chip sets that can simultaneously transmit 4 or more units. Data from the U.S. Department of Commerce indicates that the domestic hotel market consists of 1.7 million rooms, with 1.4 million rooms in buildings of more than 100 rooms. We believe that these larger buildings and complexes are the initial target for5 digital television signals plus high-speed Internet access. The commercial MTU market, also known asaccess over an ordinary pair of telephone wires from a DLC location to a neighborhood home. These factors provide a significant opportunity for a new generation of full-service broadband access systems that may be positioned alongside of existing, limited-function DLCs to provision the multi-tenant commercial unit, or MCU, market, represents office complexesbundled voice, data, and other business-related facilities. According to data from Torto Wheaton Research, there is more than 2.5 billion square feet of rentable commercial office space invideo services demanded by the 54 largest metropolitan markets across the United States. MTUmarketplace.
Multi-Tenant Unit (MTU) Market Characteristics Since
As the demand for high-speed Internet access has increased significantly over the last couple of years, we believe that owners and managers of apartments, hotels and commercial multi-tenant properties have begun to view high-speed Internet access as a critical enhanced service for their residents, guests and tenants. There is demand from owners of MTU complexes and buildings to offer Internet access and other broadband services as an amenity that effectively attracts and retains occupants, thereby increasing revenue and profitability. This demand is facilitated by worldwide telecommunications deregulation that allows the existing in-building telephone wires to be used by a CLEC to provide voice, video, and/or data services—in many cases without having to pay compensation to the ILEC since these facilities are now under control of the property owner.
Given the complexity and cost of deploying broadband services, many property owners prefer to outsource ownership, installation, operation and management of high-speed Internet solutions to an MTU-focused service provider. In exchange for granting a service provider the ability to market and provide telecommunications services to their properties, these MTU owners have an opportunity to offer new Internet-enabled services to their tenants and to potentially share in some of the service revenues generated from their buildings. These services enable on-line reservation of building amenities, community message boards, e- commerce and electronic payment of rent.
A set of specialized service providers and divisions of incumbent service providersILECs have emerged over the last few years to filladdress the growing demand for high-speed Internet service to the MTU market. While high-speed Internet access is the primary service delivered by these service providers today, we believe that the delivery of multiple services, such as high-speed corporate networking, packet voice and IP video, will be the key to meeting future customer needs and driving service provider profitability through bundled service offerings. The MTU market is attractive to these service providers because of the efficiency of delivering multiple services, often on an exclusive basis, to a geographically concentrated and demographically similar customer base. 2 Infrastructure Requirements for MTU Service Providers Service providers marketing to MTU owners and tenants typically concentrate their networks, as well as sales and marketing efforts within major metropolitan areas. In each local service area, a service provider will locate a metropolitan point-of-presence, or metro POP, that will concentrate high- speed, last mile access links from multiple MTUs, provide value-added services such as web hosting and e-mail, manage subscriber access, centralize billing, and provide an efficient link to backbone Internet or intranet networks. The high-speed links from a service provider's metro POP to individual MTU buildings or complexes may consist of local T1 facilities sourced from an ILEC, xDSL facilities sourced from a competitive local exchange carrier, or CLEC, or self-provisioned fiber, coaxial cable, or radio facilities. Once broadband access is brought to the MTU, another broadband distribution network needs to be created within the building to bring the offered services to tenants. Alternatives for creating this network include rewiring the building with Category 5 copper wire for Ethernet, laying a new fiber-based infrastructure or reusing the copper infrastructure that is already in place to provide telephone service. Rewiring with Category 5 wire or laying new fiber links can be prohibitively expensive on a per-subscriber basis because in most cases a service provider will only have demand from a limited number of tenants in the building, yet the entire building will need to be rewired to accommodate future and changing requirements. Similarly, carrier class DSL access multiplexers, known as DSLAMs, which are designed to serve hundreds of subscribers over the existing telephone wires, are prohibitively expensive when only serving a limited number of tenants. We believe that service providers for the MTU market require systems that: . deliver reliable high-quality broadband access services in a cost effective manner; . are easy to deploy and provision, and are economically scalable from as few as four subscribers in small buildings to hundreds of subscribers in large complexes; . support and manage the bandwidth for multiple services such as voice, video, and VPN networking so as to maximize both the network infrastructure and the sales, marketing and operations infrastructure of the service provider; and . are remotely controlled, maintained and upgraded as required. We believe that systems with these characteristics enable service providers to increase their revenue by providing additional services and increase customer retention through bundled service offerings.

Customers and Markets
We targetdevelop, market and focus our development, marketing and sales efforts to service providers in both the MDUNDU and MCUMTU markets. MDU
NDU Market
Over the last year the incumbent carriers have witnessed significant growth in demand for high-speed Internet access services, a significant increase in market penetration by competitive cable operators into the carriers’ core telephony services market, and expanded deregulation. These factors have increased the interest and commitment of carriers to deploy advanced broadband capabilities in a bundled full-service package to residential markets. We believe that service providers can deliver broadband services in the most cost-effective manner by using VDSL within a neighborhood community for the last mile of service connectivity over the existing copper infrastructure.
Our potential customers in the NDU market are the largest telecommunications carriers around the world, the former RBOCs and the PTTs that plan to offer a full set of services to their customers. The services envisioned include digital broadcast television channels and video-on-demand services to multiple televisions per household in addition to high-speed Internet access and telephony services. To the extent possible, the former RBOCs and PTTs will leverage their existing fiber and copper infrastructures to deliver these services.
MTU Market
Service providers, including ILECs, PTTs,incumbent carriers, CLECs, ISPs and multiple system operators for the cable industry, can recognize substantial economies of scale by providing high-speed services to MDU tenants of an MTU building from a single point of service. MDUspresence on the MTU property. MTUs include apartment complexes, hotels, university dormitories, andhospitals, military housing complexes. We believe that the potential international MDU market represents a strategic opportunity for us. complexes, high-rise office buildings and commercial campus environments.

Our Expresso MDU and SMS 2000 system hassystems have been designed with features to specifically address the needs of this market. Among our Expresso MDU customers throughout mostDue to the demise of many domestic competitive service providers over the calendar year 2000 were CAIS, Inc., Darwin Networks, Inc., I-Quest Corporation, Reflex Communications, Inc., and Velocity HSI, Inc. Abrupt changes in the capital markets have led each of these companies to narrow the focus of their market activities and severely curtail previous levels of operations including their deployment of our product. In the case of Darwin Networks, Inc., in January 2001, they filed for 7 Chapter 11 bankruptcy protection. In the case Reflex Communications, Inc., in March 2001, they filed for Chapter 7 bankruptcy protection. We also saw a fall off in sales to customers in the Korean market, including sales to TriGem InfoComm, as a result of regulatory and other changes within that marketplace. As a result,last 12 months, we are depending more heavily on the development of our relationships with other international customers and thecertain business divisions of ILECs, CLECs and PTTs. MCU Market For some time there have been service providers focused on delivering voice services to tenants in multi-tenant commercial buildings, but over the last few years, a new class of service providers and business divisions of ILECs and PTTs have emerged that plan to use broadband IP-based infrastructures to provide a wide array of bundled services, including high-speed Internet access, email, web hosting, firewall protection, local and long distance voice, and business TV to tenants in multi-tenant commercial buildings. These MCU service providers are demanding a low-cost, multi-service, broadband platform on which to deliver this array of services to the small and medium size businesses that tend to locate in MCUs. Among our current MCU customers are Cygcom Integrated Technologies, Inc., Newcom Americas, Inc., Rikei Corporation and Rycom CCI, Inc. The initial version of our IntelliPOP system has been designed to specifically address the needs of the MCU market in terms of performance, size, and ease of installation. We believe that IntelliPOP incorporates the high- speed access technologies, high-performance processing technologies, and sophisticated bandwidth management techniques required by business end users. At the same time, the IntelliPOP Service Gateway is designed to be an easy-to- deploy rack-mountable or wall-mountable unit that is less than two inches high allowingincumbent carriers for easy and cost-effective deployment in the smallest of multi-tenant buildings. Several existing and potential customers are currently evaluating the IntelliPOP product. For simple point-to-point applications, we market our XL products to domestic and international end users for LAN extensions over existing copper telephone wires. We have several hundred domestic and international customers for our XL product line. Home Networking The growth in the demand for high-speed data access, the decreasing cost of personal computers and the proliferation of Internet access devices in homes are creating an emerging demand for home networking and access solutions. Home networks must be designed to allow the sharing of files, the sharing of peripherals, such as printers, the simultaneous, uninterrupted use of voice service and, perhaps most importantly, the sharing of Internet and remote corporate network access. Home network consumers desire a low cost, easy to implement network solution that does not require new wires to be installed throughout the home. We are licensing our HomeRun technology to members of the HomePNA and others. In 1998, the HomePNA selected HomeRun as the initial specification for a home networking standard. The founding members of the HomePNA were 3Com Corporation, Advanced Micro Devices, Inc., Agere Systems (assigned from Lucent Technologies, Inc.), AT&T Wireless Services, Broadcom Corporation (purchased Epigram Corporation), Compaq Computer Corporation, Conexant Systems, Inc., Hewlett-Packard Co., Intel Corporation, International Business Machines and Tut Systems.

Additionally, our active involvement in industry based standards associations, such as the Full Service-VDSL Committee, enables us to incorporate recommended platform architectures and standards into our technology.
Manufacturing
We do not manufacture any of our own products. We rely on contract manufacturers to assemble, test and package our products. We require ISO 9002 registration for these contract manufacturers as a condition of qualification. We auditmonitor each contractor'scontractor’s manufacturing process performance through audits, testing and inspections and monitor each contractor'sinspections. Each contractor’s quality is also rigorously assessed through incoming testing and inspection of packaged products received from each contractor. In addition, we monitor the reliability of our products through in-house repair, reliability audit testing and field data analysis.
We currently purchase alla substantial portion of ourthe raw materials and components used in our products through our contract manufacturers. We and our contract manufacturers have experienced difficulty in obtaining some components used in our products. We forecast our product requirements to maintain sufficient product inventory to allow us toensure that we can meet the shortrequired delivery times demanded by our large and diverse customer base, which is typically one to four days from receipt of order to shipment to the customer.base. However, because of recent changes in the industry, we have had to cancel certain finished goods and component orders whichorders. These developments may have a negative impact on our ability to diversify our product manufacturing across a larger base of contract manufacturers. Our future success will depend in significant part on our ability to obtain manufacturing on time, at low costs and in sufficient quantities to meet demand.
Competition
Within the MTU market space, product price and gross margin associated with our sales in certain areas of the Asia-Pacific region have decreased due to intense price competition from local manufacturers of products with less advanced features. Our sales declines in the North American market have less to do with competition and more to do with the deteriorating economics of the service providers who were focused exclusively on the MTU market. To maintain a competitive position in the MTU market, we will focus our MTU product efforts on price reduction, cost reduction and feature partitioning in order to respond to competitive pressures.
The NDU market, represented by the incumbent carriers, is equally competitive yet remains a systems and application-based solution proposition, allowing us to develop feature differentiation and unique competitive positioning. Many of the competitive factors influencing procurement decisions are external to the technology and outside of our ability to control, such as:
competition against large multi-national suppliers who have both a track record and a large embedded base of ancillary technology;
incumbent carriers’ desire to try to make embedded systems meet demand for new services through future enhancements or upgrades rather than deploying new systems;

9


long evaluation cycles and expensive third party testing requirements for new technology; and
lack of clarity on certain regulatory and US congressional issues creating a potential roadblock to rapid technology adoption.
The markets for our products are intensely competitive, continually evolving and subject to rapid technological change. WeIn order to be competitive in the NDU and MTU markets, we believe that we and our products facemust continue to adhere to the following competitive factors: . conformance to industry standards; . breadth of product lines; . implementation of additional product features and enhancements, including improvements in product performance, reliability, size, and scalability; . low cost and ease of deployment and use; . sales and distribution capability; . technical support; and . service and general industry and economic conditions. principles:
conform our products to industry standards wherever possible;
offer a sufficient breadth of product lines to address the needs of the market;
continue to incorporate additional product features and enhancements in our products, including improvements in product performance, reliability, size, and scalability;
continue to design and manufacture our products with a focus on low cost and ease of deployment and use;
continue to increase the effectiveness of our sales and distribution capability;
continue to provide technical support; and
respond quickly to service and general industry and economic conditions.
Although we believe that we currently compete favorably with respect to all of these factors, there can be no assurance that we will have the financial resources, technical expertise or marketing, manufacturing, distribution and support capabilities to compete successfully in the future. We expect that competition in each of our markets will increase in the future. Our principal competitors include, or are expected to include, Cisco Systems, Inc., Copper Mountain Networks,Lucent Technologies, Inc., Elastic Networks,Next Level Communications, Inc., Paradyne Networks, Inc., and a number of other public and private companies. Many of our competitors and potential competitors have substantially greater name recognition and technical, financial and marketing resources than us.we do. These competitors may undertake more extensive marketing campaigns, adopt more aggressive pricing policies and devote substantially more resources to developing new products than us.we can. There can be no assurance that we will be able to compete successfully against current or future competitors or that competitive pressures facedthat we face will not harm our business, financial condition and results of operations. In addition, some of our HomeRun technology licensees may sellhave sold aspects of our technology to our competitors or potential competitors. These competitors may cause an erosion in the 10 potential market for our products. This competition could resulthas resulted in price reductions, reduced profit margins and loss of market share which would harmin Asia for our business, financial condition and results of operations. Expresso products.
We also compete with technologies usingthat use alternative transmission media such as coaxial cable, wireless facilities and fiber optic cable. To the extent that telecommunications service providers choose to install fiber optic cable or other transmission media in the last mile, or to the extent that homeowners and businesses install other transmission media within buildings, we expect that demand for our copper telephone wire-based products will decline. These competitive pressures from alternative transmission technologies may further necessitate price reductions in the prices of our existing and future products.
Proprietary Rights
Our success and ability to compete is dependent in part uponon our proprietary technology. We rely on a combination of patent, copyright and trade secret laws and non-disclosure agreements to protect our proprietary technology. We currently hold 2026 United States patents and have 2426 United States patent applications pending. There can be no assuranceWe cannot assure you that patents will be issued with respect to pending or future patent applications or that our patents will be upheld as valid or will prevent the development of competitive products. We seek to protect our intellectual property rights by limiting access to the distribution of our software, documentation and other proprietary information. In addition, we enter into confidentiality agreements with our employees and certain customers, vendors and strategic partners. The steps taken by uswe take in this regard may be inadequate to prevent

10


misappropriation of our technology and our competitors may independently develop technologies that are substantially equivalent or superior to our technologies. We are also subject to the risk of adverse claims and litigation alleging infringement of the intellectual property rights of others. In this regard, there can be no assurance that third parties will not assert infringement claims in the future with respect to our current or future products or that any of thesesuch claims will not require us to enter into license arrangements or result in protracted and costly litigation, regardless of the merits of those claims. No assurance can be givenWe cannot assure you that any necessary licenses will be available or that, if available, these licenses can be obtained on commercially reasonable terms.

Overview
We design, develop, and market multi-service broadbandfull-service access systems thatwhich enable service providers to deliver broadband services to single-family homes, referred to as neighborhood dwelling units, or NDUs, and to tenants residing in multi-tenant unit properties, or MTUs. Our systems use the existing copper telephone wiring found in neighborhoods and buildings to simultaneously deliver multiple broadband services such as interactive digital broadcast television, video-on-demand services, telecommuter data service, high-speed Internet access and high-quality voice services over a single pair of telephone-grade wires. Our target customers are broadband service providers that include telephony-based incumbent local exchange companies, or ILECs, such as the former Regional Bell Operating Companies, or RBOCs, and international Post, Telephone, and Telegraph companies, or PTTs, as well as regulated and unregulated competitive local exchange carriers, or CLECs, who aim to deliver services over existing copper infrastructures.
We have incurred net operating losses to date and, as of December 31, 2001, had an accumulated deficit of $234.9 million. Our ability to generate income from operations will be primarily dependent on increases in sales volume, reductions in manufacturing costs and the growth of high-speed data access to multi-tenant buildings. We use our proprietary FastCopper technology to deliver cost- effective, scalablesolutions in the NDU and easy to deploy solutions that exploit the underutilized bandwidth of copper telephone wires within these buildings. Our collection of FastCopper technologies includes HomeRun, which was selected as the initial specification for a home networking standard promoted by the HomePNA, and LongRun, a proprietary extension of HomeRun providing superior performance at longer distances. These technologies are deployed through our Expresso high- bandwidth access multiplexers and associated routers.MTU markets. In addition to our Expresso access multiplexers are our products that provide service providers with enhanced capabilities such as subscriber management, bandwidth management, IP address management, and network address translation. Recently, we introduced our IntelliPOP product line with proprietary Signature Switch technology. Our proprietary Signature Switch technology is designed to allow service providers to manage and guarantee bandwidth and service performance across applications such as IP telephony, VPN networking, videoconferencing, video-on-demand, file transfer and Internet access, and to efficiently configure IntelliPOP for the delivery of these services according to the unique market requirements of multi-tenant building owners and end-user subscribers on an individual or collective basis. We commenced operations in August 1991. Through the third quarter of 1998, substantially allview of our limited history of product revenue was derived from new markets, our reliance on growth in deployment of high-speed data access solutions and the saleunpredictability of orders and subsequent revenue, we believe that period-to-period comparisons of our XL Ethernet LAN extension productsfinancial results are not necessarily meaningful and should not be relied upon as an indication of future performance. Failure to the corporate and university segments of the MCU market. In early 1997, we introduced the first products in our Expresso product line aimed at service provider markets. During the first quarter of 1998, we began licensing our HomeRun technology to certain leading semiconductor, computer hardware and consumer electronics manufacturers for incorporation into integrated circuits and consumer products including PCs, peripherals, modems and other Internet appliances. In the third and fourth quarters of 1998, we commenced selling our Expresso GS products, which are configured for local loop applications, and Expresso MDU products, which incorporate our HomeRun technology to a broader range of service providers, primarily those serving apartment complexes, hotels, university dormitories and military complexes in the MDU market. In the first quarter of 1999, we commenced selling Expresso MDU products incorporating our LongRun technology and Expresso MDU Lite into additional segments of the MDU market. During the fourth quarter of 1999, we commenced selling our Expresso SMS 2000 and companion Expresso OCS system providing subscriber management, bandwidth management, credit card billing and other functions to the MDU market. During the first quarter of 2000, we commenced selling our OneGate Internet server appliances, acquired as a result of our FreeGate acquisition, to the MCU market. During the last quarter of 2000, our new IntelliPOP product was under evaluation by several potential customers. We generate revenue primarily from the sale of hardware products and, to a lesser extent, through the licensing of our HomeRun technology and the sale of our software products. We generally recognize product revenue when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectibility is probable. Revenue from service obligations included in product revenues is deferred and generally recognized ratably over the period of the obligation. We also maintain accruals and allowances for all cooperative marketing and other programs. Estimated sales returns, and warranty costs based on historical experience by product, are recorded at the time revenue is recognized. Our products generally carry a one year to two year warranty from the date of purchase. Estimated sales returns, and warranty costs based on historical experience by product, are recorded at the time revenue is recognized. 16 License and royalty revenue consists of nonrefundable up-front license fees, some of which may offset initial royalty payments, and royalties. Currently, the majority of our license and royalty revenue is comprised of non-refundable license fees paid in advance. Such revenue is recognized ratably over the period during which post-contract customer support is expected to be provided or upon delivery and transfer of agreed upon technical specifications in contracts where essentially no further support obligations exist. Future license and royalty revenue is expected to consist primarily of royalties based on products sold by our licensees. We do not expect that such license and royalty revenue will constitute a substantial portion of our revenue in future periods. With the introduction of our IntelliPOP product line, we expect thatsignificant revenue from existing or new products, whether due to lack of market acceptance, competition, technological change, continued poor economic conditions affecting the saletelecommunications industry or otherwise, or the inability to reduce manufacturing costs, will harm our business, financial condition and results of software products and maintenance fees will constitute a substantial portionoperations.
During 2001, we have reduced the sales prices of revenue in future periods. We expect that sales price reductions on some of our products will be necessary to remain competitive and to reduce our relatively high levels of inventory. Although we have historically been able to offset most price declines with reductions in our manufacturing costs, there can be no assurance that we will be able to offset further price declines with additional cost reductions. Also, market developments, including the write down of significant amounts of inventory by competitors and products resold as a result of bankruptcies within the industry, have put increased pressure on the sales prices of our existing inventories. In addition, some of our licensees may sell products based on our technology to our competitors or potential competitors. There can be no assuranceWe cannot assure you that our HomeRun technology will be successfully deployed on a widespread basis or that such licensing will not result in an erosion of the potential market for our products.
Sales to customers outside of the United States accounted for approximately 41.0%56.3%, 32.3%41.0% and 18.5%32.3% of revenue for the years ended December 31, 2001, 2000 1999 and 1998,1999, respectively. On average, we expect international sales to represent approximately one-half or less50% of our revenue. However, actual results, both geographically and in absolute dollars, may vary from quarter to quarter depending on the timing of orders placed by customers. To date, all international sales have been denominated in U.S. dollars.
We expect to continue to evaluate product line expansion and new product opportunities, engage in extensive research, development and engineering activities and focus on cost-effective design of our products. Accordingly, we will continue to make significant expenditures on sales and marketing, and research and development activities. activities as a percentage of overall operating expenses.

This transaction was treated as a purchase of assets for accounting purposes. The acquired patents and technology of ViaGate provide a highly scalable, carrier-class, full service gateway built on standards-based asynchronous transfer mode, or ATM, IP and VDSL technology.
While we expect to derive benefits from sales of product lines that are designed, developed and marketed as a result of these acquisitions, there can be no assurance that we will be able to complete the development and commercial deployment of certain of these products or expand sales of those products which have already been completed.products. In January 2001, we decided to abandon future sales of the existing OneGate product that we acquired in the FreeGate acquisition. TheIn April 2001, as part of our cost reduction efforts, we decided not to pursue further incorporation of the related OneGate and other intellectual property acquired from FreeGate is being incorporated into the design of future products. Through theseAs a result, we took a write down of $2.7 million for abandonment of the related completed transactions,technology and patents in the first quarter of 2001. During our impairment review for the third quarter of 2001, we have added approximately 80 peopleevaluated the present value of future expected cash flows to determine the fair value of our workforce.long-lived assets. This evaluation resulted in a write down of $29.9 million of goodwill and other intangible assets. The costs associated with personnel including rent for additional facilitiesunderlying factors contributing to the decline in expected future cash flows include a continued decline in the telecommunications industry and the indefinite postponement of capital

expenditures, especially within the hospitality industry. As of December 31, 2001, our net intangible assets remaining to be amortized were $4.3 million, comprised entirely of completed technology and patents related generalto the acquisitions of the ViaGate assets and administrative costs as well as costs associated with research and development, and sales and marketing activities substantially increased our operating costs in fiscal year 2000 when compared to related costs expended in fiscal year 1999. Xstreamis.
In January 2001, April 2001 and October 2001, we reduced our total workforce by 10%, 28% and 11%, respectively, in effortsan effort to control overall operating expenses in response to recent declines in and expected slowingslower growth in our sales. In April 2001, we also implemented plans to close several of our sales growth.satellite offices. We have incurred net operating lossesrestructuring charges of $2.1 million related to datethe April 2001 restructuring and as of December 31, 2000, had an accumulated deficit of $130.6 million. Our ability$0.2 million related to generate income from operations will be primarily dependent on increases in sales volume, reductions in manufacturing costs and the growth of high-speed data access solutions in the service provider and MTU markets. In view of our limited history of product revenue from new markets, reliance on growth in deployment of high-speed data access solutions and the unpredictability of orders and subsequent revenue, we believe that period to period comparisons of our financial results are not necessarily meaningful and should not be relied upon as an indication of future performance. Failure to generate significant revenue from new products, whether due to lack of market acceptance, competition, technological change or otherwise, or the inability to reduce manufacturing costs, will harm our business, financial condition and results of operations. 18 October 2001 restructuring.

Revenue.    We generate revenue primarily from the sale of hardware products and, to a lesser extent, through the licensing of our HomeRun technology and from the sale of software products. Our total revenue increaseddecreased to $13.7 million for the year ended December 31, 2001 from $72.0 million for the year ended December 31, 2000 and from $27.8 million for the year ended December 31, 1999, and from $10.6 million for the year ended December 31, 1998.1999. Using a year-over-year comparison, the increasesdecrease in 2001 compared to 2000 and 1999 wereof $58.2 million or 80.9% was primarily due to increased decreased

sales of our Expresso MDU products. However, duringThe market for our products was significantly weaker in 2001 than it was in 2000. During the fourth quarter of 2000, our revenue growth slowed substantially due to (i) several key customers who, in the latter part of the fourth quarter of 2000, experienced a rapid deterioration in their ability to obtain additional capital and, as a result, severely curtailed or halted their purchases of our product, and also due to a fall-off(ii) reduced sales volume in sales to the Korean market. ThisThe fourth quarter of 2000 revenue declines resulted in fourth quarter revenues of $5.9 million compared with revenues of $66.1 million for the first three quarters of 2000 in aggregate and $10.6 million for the fourth quarter of 1999. These developments were not unique to us and have continued in conjunction with a general downturn in the telecommunications market throughout 2001, affecting our ability to generate comparatively similar levels of sales. In certain instances, these developments have made collection of receivables less certain and require us to defer revenue until cash is collected. During the third quarter of 2001, our revenue growth further slowed due to an increase in the number of customers and potential customers, particularly within the hospitality industry, that indefinitely postponed capital expenditures after the events surrounding September 11, 2001. The increase in 2000 compared to 1999 of $44.2 million or 158.9% was primarily due to increased sales of our Expresso MDU products.
License and royalty revenue increaseddecreased to $0.9 million for the year ended December 31, 2001 from $2.0 million for the year ended December 31, 2000 and from $1.5 million for the year ended December 31, 1999, and from $0.81999. The decrease in 2001 compared to 2000 of $1.1 million foror 56.1% was primarily due to decreases in royalty payments, as a result of continued economic conditions affecting the year ended December 31, 1998.telecommunications market. The increase in license and royalty revenue in 2000 compared to 1999 of $0.5 million or 30.4% was primarily due to increases in royalty payments. The increase in 1999 was primarily due to increases in up-frontpayments for products sold by our licensees. We did not enter into any new license fees recognizedor royalty agreements during the year and receipt of related royalty payments. There was2001. We entered into one new license and royalty agreement signed during fiscal year 2000.

Cost of goods sold consists of raw materials, contract manufacturing, personnel costs, test and quality assurance for products, and the cost of licensed technology included in the products. Our costExcluding the reserves for excess and obsolete inventory of goods sold before$29.9 million taken in 2001 and the provision for loss on purchase commitments and abandoned products increasedof $27.2 million, our cost of goods sold decreased to $10.6 million in 2001, from $42.8 million for the year ended December 31, 2000 and from $15.5 million for the year ended December 31, 1999, and from $5.8in 1999. The decrease in 2001 compared to 2000 of $32.2 million for the year ended December 31, 1998.or 75.3% was primarily due to decreased sales of our Expresso MDU products. The increasesincrease in 2000 andcompared to 1999 wereof $27.3 million or 176.6% was primarily due to increased production of our Expresso MDU products. Our gross

Gross margin before provision for loss on purchase commitments and abandoned products as a percentage of revenue decreased to 40.6% of revenue for the year ended December 31, 2000, and from 44.4% of revenue for the year ended December 31, 1999, and from 45.0% of revenue for the year ended December 31, 1998.1999. The decrease in gross margin before such provisions as2001 compared to 2000 of 17.4% was due primarily to sales price reductions on some of our Expresso MDU products in response to competitive pricing pressures and to a percentage oflesser extent to fixed manufacturing costs that could not be reduced proportionately in relation to the decreased revenue in 2001. The decrease in 2000 compared to 1999 of 3.8% was due primarily to fourth quarter introductions of new products in the Expresso MDU product line which had

20


lower than average gross margins, increases in inventory reserves related to estimated losses on custom built products and older product versions that were not upgraded in light of fourth quarter of 2000 industry slowdowns, higher costs of scarce component parts which could not be offset by further product cost reductions, and fixed manufacturing costs which could not be reduced in correlation with the rapid decline of revenue in the fourth quarter.
In 1999, no significant adjustments for inventory were recorded.
During the fourth quarter of 2000, we recognized a charge related to provision for loss on purchase commitments and abandoned product lines of $27.2 million. TheThis provision covers estimated costs for the cancellation of inventory purchase commitments that resulted from industry slow downs of large scale deployments in the MTU market and actual costs forof inventory of abandoned product lines no longer deemed essential to our core technologies in the future. The cost of these abandoned products was $8.2 million and included OneGate products, certain Expresso GS line cards and routers, and certain subscriber management software. This charge was included in cost of goods sold, resulting in an overall gross margin of 2.8% for 2000. The decrease
During 2001, we reversed $2.9 million of the provision for loss on purchase commitments against cost of goods sold and we paid our suppliers $11.8 million upon receipt of raw material components related to our provision of loss on purchase commitments recorded in the fourth quarter of 2000. At December 31, 2001, these components were included in inventory offset by the provision for $11.8 million. There were no additional provisions recorded in 2001 related to these raw material components. In 2001, cost of goods sold also included approximately $0.5 million for the sale of raw materials previously reserved through the loss on purchase commitments.
During the first quarter of 2001, we recorded a reserve for excess and obsolete inventory of $18.5 million. This reserve was primarily related to the costs of raw materials and finished goods in excess of what we reasonably expected to sell in the foreseeable future as of the first quarter of 2001. During the third quarter of 2001, we recorded an additional reserve for excess and obsolete inventory of $11.4 million. This reserve was primarily related to the costs of raw materials and finished goods in excess of revised projections of what we reasonably expected to sell in the foreseeable future. Market developments over the past year, including the write down of significant amounts of inventory by competitors, the proliferation of products resold as a result of bankruptcies within the industry, continued slowdown in the telecommunications market and more recently, the indefinite postponement of capital expenditures, especially within the hospitality industry, have contributed to substantial uncertainties related to the value of these inventories. During the year, we also recorded additional reserves of $4.3 million for excess and obsolete inventory as a part of our normal business operations and product inventory assessments. All of these inventory adjustments for 2001 were included in cost of goods sold resulting in an overall negative gross margin as a percent of revenue in 1999 from 1998 was primarily due to the change in product mix, as we sold a larger percentage of Expresso products that had lower average gross margins than the XL products. (194.5)%.
Sales and Marketing.    Sales and marketing expense primarily consists of personnel costs, including commissions and costs related to customer support, travel, trade shows, promotions and outside services. Our sales and marketing expenses increaseddecreased to $12.4 million for the year ended December 31, 2001 from $19.9 million for the year ended December 31, 2000, and increased from $10.5 million for the year ended December 31, 1999. The decrease in 2001 when compared to 2000 of $7.5 million or 37.8% was primarily due to reduction in our marketing programs in order to reduce our costs in light of the difficult market conditions in 2001 and, to a lesser degree, to align our sales commission expense with lower revenue in 2001. The increase in sales and marketing expenses in 2000 when compared to 1999 and from $8.5of $9.4 million for the year ended December 31, 1998. The increases in both 2000 and 1999 wereor 89.5% was primarily due to increased hiring of sales and marketing personnel. These increases were also due to travel, attendance at trade shows as well asand increases in personnel related to customer support activities and expanded efforts in international markets.
Research and Development.    Research and development expense consists primarily consists of personnel costs related to engineering and technical support, contract consultants, outside testing services, equipment and

21


supplies associated with enhancing existing products and developing new products. Research and development costs are expensed as they are incurred. Our research and development expenses increaseddecreased to $15.0 million for the year ended December 31, 2001 from $17.1 million for the year ended December 31, 2000 and increased from $7.6 million for the year ended December 31, 1999,1999. The decrease in 2001 when compared to 2000 of $2.1 million or 12.3% was primarily a result of our workforce reductions in 2001 and from $6.2 million forour continued focus on cost saving measures, including the year ended December 31, 1998.reduction, postponement or abandonment of research and development efforts on certain of our product lines. The increase in 2000 compared to 1999 of $9.5 million or 125.1% was primarily due to further development of the Expresso MDU products, development of HomeRun-related products, continued development of the subscriber management system portion of the Expresso MDU product line and initial development of our IntelliPOP platform. The research and development expenses of FreeGate, Xstreamis and XstreamisActiveTelco were consolidated with our expenses for the periods subsequent to the respective February 2000, and May 2000 and January 2001 acquisitions. Additionally, in 2001 and 2000, we amortized to research and development $0.8 million and $2.0 million, respectively, of deferred compensation and notes receivable to research and development related to restricted stock granted to certain FreeGate, OneWorld and OneWorldActiveTelco employees. Approximately $1.3 millionAs of the remainingDecember 31, 2001, nominal balances related to deferred compensation and notes receivable have beenare recorded as a reduction of equity in the balance sheet. We intend to recognizewill either amortize this remaining balance or collect the expense ratably overnote receivable balance depending on the remaining period in which the restrictions lapse, currently estimated at eightterms and ten months for each of FreeGate and OneWorld, respectively. The increase in 1999 was primarily due to further developmentconditions of the Expresso GSnotes. Research and Expresso MDU products, 20 development expenses decreased in absolute dollars in 2001, as a result of HomeRun-related products, enhancement of certain XL products, andour continued development of the subscriber management system portion of the Expresso MDU product line. Thefocus on cost saving measures. We expect research and development activities to represent a significant percentage of our overall fixed operating expenses of PublicPort and Vintel were consolidated with our expenses for the periods subsequent to the respective June 1999 and November 1999 acquisitions. We intend to increase investment in research and development programs in future periods for the purpose of enhancing current products to provide advanced Internet service applications for both domestic and international markets, reducing the cost of current products, and developing and acquiring new products. during 2002.
General and Administrative.    General and administrative expense primarily consists of personnel costs for administrative officers and support personnel, and legal, accounting, insurance and consulting fees. Our general and administrative expenses increaseddecreased to $9.1 million for the year ended December 31, 2001 from $11.5 million for the year ended December 31, 2000 and increased from $4.2 million for the year ended December 31, 1999,1999. The decrease in 2001 compared to 2000 of $2.4 million or 20.7% was primarily a result of our workforce reductions in 2001, recovery of bad debt of $1.8 million and fromour continued focus on cost saving measures. This decrease was offset by higher insurance of $1.4 million and professional service fees of $2.7 million for the year ended December 31, 1998.that we incurred in 2001 compared to $0.4 million and $2.4 million, respectively in 2000. The increasesincrease in both 2000 andcompared to 1999 wereof $7.3 million or 174.3% was primarily due to additionsthe addition of administrative personnel and increasesan increase in other costs related to our growth. We intend to increaseanticipate that general and administrative expendituresexpenses will increase in 2002 because we do not expect significant bad debt recovery in 2002.
Restructuring Costs.    We incurred restructuring costs of $2.3 million for the year ended December 31, 2001. We did not incur any restructuring costs in 2000 or 1999. In April 2001, we announced a restructuring program that included a 28% workforce reduction, closure of excess facilities, and infrastructurethe disposition of certain fixed assets. As a result of this restructuring program, we recorded restructuring costs of $2.1 million in the second quarter of 2001. These restructuring costs were comprised of $1.2 million in workforce reduction charges relating primarily to severance and related benefits, $0.8 million relating to closure of excess facilities and $0.1 million in other fixed assets retired as a result of the workforce reductions. In October 2001, we expandfurther reduced our business. total workforce by 11%, which resulted in restructuring costs of $0.2 million during the fourth quarter of 2001, comprised of severance and related benefits. Our workforce reductions in 2001 arose from an effort to control overall operating expenses in response to recent declines and expected slower growth in our sales.
In-Process Research and Development.    Amounts expensed as in-process research and development were $1.2 million in 2001, $0.8 million in 2000 and $2.6 million in 1999, and were related to in-process research and development purchased from ActiveTelco, FreeGate and Vintel, respectively. There

In-Process Research and Development, Vintel.    Amounts expensed as in-process research and development were $2.6 million for the year ended December 31, 1999 and were related to in-process research and development purchased from Vintel. The purchased in-process technology was expensed upon acquisition because technological feasibility had not been established and no future alternative uses existed. The in-process technology percentage of completion was estimated to be 75%. The value of this in-process technology was determined by estimating the costscost to develop the purchased in-process technology into a commercially viable product, estimating the resulting net cash flows from the sale of the product resulting from the completion of the in-process technology and discounting the net cash flows back to their present value using a risk- weightedrisk-weighted discount rate of 30%.

Impairment of Intangibles.    Based on the impairment review performed during the third quarter of 2001, we recorded a $29.9 million impairment charge to write off all of the remaining goodwill and assembled workforce and reduce the book value of our completed technology and patents. The charge was determined based upon estimated discounted future cash flows using a discount rate of 20%. The assumptions supporting future cash flows, including the discount rate, were determined using management’s best estimates. The underlying factors contributing to the decline in expected future cash flows include a continued slowdown in the telecommunications market, and more recently, the indefinite postponement of capital expenditures, particularly within the hospitality industry. In the first quarter of 2001, we recorded a $2.7 million impairment charge to write off the completed technology and patents of FreeGate. This resulted from our decision not to pursue further incorporation of the related OneGate product and other intellectual property acquired from FreeGate into the design of future products. Total impairment of intangibles was $32.6 million for the year ended December 31, 2001. There were no such impairments for the years ended December 31, 2000 and 1999. As of December 31, 2001, our net intangible assets remaining to be amortized were $4.3 million, comprised entirely of completed technology and patents related to the acquisitions of the ViaGate assets and Xstreamis.
Amortization of Intangibles.    Amortization of intangibles consistsis comprised of the periodic amortization of intangible assets related to the purchase acquisitions of Vintel in 1999, FreeGate, OneWorld assets and Xstreamis.Xstreamis in 2000, and ActiveTelco and ViaGate assets in 2001. These intangible assets consistconsisted primarily of assembled workforce, completed technology and patents, and goodwill, and each are amortized over their estimated useful lives of three, five and five years, respectively. Amortization of intangibles increased to $8.1 million for the year ended December 31, 2001 from $7.6 million for the year ended December 31, 2000 and from $0.1 million for the year ended December 31, 1999. There were no such costsThe increases in 2001 of $0.5 million and in 2000 of $7.6 million relate to the year endedadditional amortization of intangibles arising from the acquisitions during those years. We expect a significant

Noncash Compensation Expense.    Noncash compensation expense in 2001, 2000 and 1999 consisted of the recognition of expense related to certain employee stock option grants based on the difference between the deemed fair value of our common stock and the stock option exercise price at the date of grant. Noncash compensation expense in 1998 primarily consisted of expenses related to the grant of a warrant to purchase up to 666,836 shares of common stock in consideration for technology endorsement, marketing and certain development support by Microsoft with respect to our HomeRun technology and related products. Noncash compensation expense in 1998 also consisted of the recognition of expense related to certain employee stock option grants. Our noncash compensation expense was $0.2 million, $0.4 million $0.5 million and $1.2$0.5 million for the years ended December 31, 2001, 2000 and 1999, and 1998, respectively. We intend to recognize $0.3 million in additionalAs of December 31, 2001, we have recognized all of the expenses related to these employee stock options ratably over the remaining vesting period of the related options. Such deferred expense has been recorded as a reduction of equity in the balance sheet.
Provision for Doubtful Accounts.    Provision for doubtful accounts consisted of the recognition of bad debt expense related to past due accounts receivable balances. The provision for doubtful accounts increaseddecreased to $0.8 million for the year ended December 31, 2001, from $22.5 million for the year ended December 31, 2000, and increased from $0.2 million for the year ended December 31, 1999,1999. The decrease in 2001 of $21.7 million or 96.2% was primarily related to lower sales volume in 2001 and from $0.1 millionno requirement for additional provisions in 2001 following the year ended December 31, 1998.business deterioration experienced by our customers in the fourth quarter of 2000. The increase in 2000 relative to 1999 of $22.3 million was primarily due to provisions recorded on past due accounts receivable from several key customers who, during the latter part of the fourth quarter of 2000, experienced a rapid deterioration in their ability to obtain additional capital, to fund their business models, declared their inability to make timely payments on their accounts, and as of the date of this report, have not been able to demonstrate wherewithal to pay their outstanding account balances.balances with us. During 2001, we recovered $1.8 million in bad debt previously written off in 2000. This bad debt recovery is included as a reduction to general and administrative expenses for 2001.

The other customers may be forcedtheir outstanding balances owed to follow similar protection options in the event capital funding does not materialize. us have been written off.
Impairment of Certain Equity Investments.    Impairment of certain equity investments for the year ended December 31, 2000 consisted of the recognition of expense related to the write off of $3.1 million invested in three nonpublicly tradedprivately-held companies. The value of these investments was impaired due to uncertainty associated with the on-going viability of each of thethese businesses in the current network infrastructure industry. There was no such impairment of our equity investments for the years ended December 31, 2001 or 1999. As of December 31, 2001, we had one remaining investment in 1999 or 1998. a privately-held company of $0.6 million.
Interest Expense. Interest expense consisted of interest expense associated with credit facilities.    Our interest expense decreasedwas nominal for the year ended December 31, 2001 compared to $0.4 million for the year ended December 31, 2000 fromand $0.6 million for the year ended December 31, 1999.

The increasefacilities in 1999 was primarily due to higher average principal owed on our credit facilities during fiscal 1999 as compared to fiscal 1998. June 2000.
Interest Income.    Interest income consisted of interest income on our cash, investments and notes receivable balances, offset by the amortization of premiums paid on investments. Our interest income increaseddecreased to $3.3 million for the year ended December 31, 2001 from $7.4 million for the year ended December 31, 2000, which increased from $2.2 million for the year ended December 31, 1999. The decrease in 2001 compared to 2000 of $4.1 million or 55.6% was primarily due to lower interest rates on lower average cash and investment balances. The increase in 2000 compared to 1999 of $5.2 million or 236.5% was primarily due to higher interest rates on higher average cash and from $0.3investment balances.

Liquidity and Capital Resources
Historically, our principal source of liquidity has been obtained through equity funding. From our inception through January 1999, we have financed our operations primarily through the sale of preferred equity securities for an aggregate of $46.2 million net of offering costs. In January 1999, we completed our initial public offering and issued 2,875,000 shares of our common stock at a price of $18.00. We received approximately $46.9 million in cash, net of underwriting discounts, commissions and other offering costs. We also received approximately $6.7 million as a result of the exercise of a warrant to purchase 666,836 shares of Series G convertible preferred stock at a price of $10.00 per share. In March 2000, we completed our secondary offering and issued 2,500,000 shares of our common stock at a price of $60.00 and we received approximately $141.7 million in cash, net of underwriting discounts, commissions and other offering costs. 22 As of December 31, 2000,In the future, we had cash,cannot be certain that similar equity funding will be available to us and as a result, our business, operating results and financial condition could be negatively impacted.
Cash, cash equivalents and short-term investments totaled $49.4 million at December 31, 2001, a decrease of $53.2 million or 51.9% from $102.6 million compared to $32.2 million as ofat December 31, 1999. 2000.
The net decrease in cash and cash equivalents of $1.0 million during the year ended December 31, 2001 resulted primarily from our use of $51.2 million for operating activities, the purchase of property and equipment of $1.2 million, the purchase of other assets of $1.2 million, which includes the acquisition of certain ViaGate assets for $0.6 million, and acquisition costs related to ActiveTelco of $0.2 million. The net decrease in cash and cash equivalents from these uses was offset by $52.4 million in proceeds from the maturities in short-term investments, net of purchases of investments, the issuance of common stock related to the exercise of stock options and purchases made pursuant to the employee stock purchase plan of $0.2 million and other proceeds from financing activities of $0.1 million.
The net increase in cash and cash equivalents of $33.9 million during the year ended December 31, 2000 resulted primarily from net proceeds from our secondary offering of $141.7 million and proceeds from the issuance of common stock related to the exercise of stock options and purchases made pursuant to the employee stock purchasespurchase plan of $4.9 million. The increases in cash and cash equivalents from these sources were offset by uses in operating activities of $63.8 million, the purchase of property and equipment of $8.6 million, the purchase of investments and other assets, net of maturities and sales of investments, of $36.6 million, the payoffrepayment of borrowings under a credit facility of $1.5 million, the acquisition costs for FreeGate, OneWorld and Xstreamis of $1.8 million and other financing activities of $0.4 million.
The net increase in cash and cash equivalents of $9.0 million during the year ended December 31, 1999 resulted primarily from net proceeds from our initial public offering of $46.9 million, net proceeds from the exercise of a warrant for convertible preferred stock of $6.7 million, proceeds from the issuance of common stock related to the exercise of stock options and purchases made pursuant to the employee stock purchase plan of $0.7 million, and proceeds from the acquisition of Vintel of $0.4 million. The increases in cash and cash equivalents from these sources were offset by uses in operating activities of $19.8 million, the purchase of investments, net of proceeds from sales and maturities of investments, of $20.7 million, the purchase of property and equipment of $2.5 million, and the payoffrepayment of borrowings under a credit facilitiesfacility of $2.7 million. The net
In future periods, we generally anticipate a decrease in cashworking capital expenditures on a period-to-period basis primarily as a result of completing a substantial portion of payments for purchase commitments for inventory and cash equivalents of $0.9 million during the year ended December 31, 1998 resulted primarily from uses for operating activities of $12.7 milliona general decrease in our operational costs due to our recent workforce reductions.

These decreasescommitments that could result in cash and cash equivalents were offset by proceeds from sales and maturities of short term investments net of purchases of short- term investments of $5.1 million, proceeds from the sale of preferred securities of $3.8 million and borrowings from credit facilities net of repayments of $3.9 million.outflows. In the first quarter of 2000, we entered into a lease for administrative and engineering facilities.facilities in Pleasanton, California. Under the terms of the lease, we were required to issue a letter of credit in the amount of $1.8$1.9 million. The letter of credit is reduced annually, beginning July 1, 2001, by approximately $0.3 million, provided that we are not in default under the terms of the lease agreement. Pursuant to these terms, our letter of

25


credit was reduced from $1.9 million to $1.6 million in the third quarter of 2001. In the fourth quarter of 2001, we entered into a lease for engineering facilities in Bridgewater Township, New Jersey. Under the terms of the lease, we were required to issue a letter of credit in the amount of $0.1 million. These letters of credit are collateralized by restricted funds in the amount of $3.2$1.7 million, which are included in intangibles and other assets as of December 31, 2000. The letter2001.
At December 31, 2001, the remaining accrual for purchase commitments of credit is reduced annually by $0.25 million providedraw material components was $4.4 million. At this time, we are notinvolved in default under the terms of the lease agreement. For future periods, we generally anticipate moderate increases in working capital on a period to period basis primarily as a result of higher relative levels of inventory. In 2000, we leased and improved facility space for administrative and engineering requirements to accommodate future growth needs through 2001. We foresee limited increases for expenditures of property and equipmentlitigation related to certain of these commitments.

To the extent that our business continues to be affected by the poor economic conditions impacting the telecommunications industry, we will continue to require cash to fund our operations, reducing our liquidity. We believe that our cash, cash equivalents and short-term investment balances will be sufficient to satisfy our cash requirements for at least the next 12 months. We expect cash flow from operations to increase during the year and we will seek additional funding for operations from alternative debt and equity sources if necessary to maintain reasonable operating levels. However, we cannot assure you that such funding efforts will be successful. Failure to generate positive cash flow in the future could harm our business, financial condition and results of operations.
Option Exchange Program We are offering our employees the opportunity
On May 14, 2001, we made an offer to cancel certain outstandingexchange all stock options in return for new options to purchase shares of our common stock equal to the number of options canceled on or about April 24, 2001. These new options will be issued to participants in the exchange program six months and two days from the day that the offer ends. The exercise price of the new options will not be determined until the date of grant, and will be set at the closing price reported on the Nasdaq National Market for our common stock on the date that is six months and one day from the end of the option exchange offer period. 23 All options held by eligible employees currently outstanding under our 1992 Stock Plan, 1998 Stock Plan and the 1999 Nonstatutory Stock Option Plan are included in the option exchange program.

Employees receiving such an offer were requested to provideread our Form 10-Q for the quarter ended March 31, 2001, a related offering memorandum and other pertinent information before making a decision with respect to the offer. Accounting and other regulatory concerns prevented or limited our ability to issue additional stock options to these employees during the period between cancellation and reissuance.

The offer expired on June 8, 2001. Pursuant to the offer, we accepted, for cancellation, stock options to purchase approximately 1,056,948 shares of our common stock at a weighted average exercise price of $35.99. Subject to the terms and conditions of the offer, on December 13, 2001, we granted new stock options to purchase a total of 850,757 shares of our common stock at an exercise price of $2.15 to those employees who holdwere employed by us at that time who had tendered stock options in response to the offer that were accepted for exchange and cancelled.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations are currently "out-of-the-money"based upon our consolidated financial statements, which have been prepared in accordance with an opportunity, so long as they are employees onaccounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the replacement grant, to exchange those old options for new stock optionsfinancial statements and the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience and on various other assumptions that are believed to be grantedreasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
We have identified the policies below as critical to our business operations and the understanding of our results of operations.
Revenue recognition
Product revenues
We generate revenue primarily from the sale of hardware products and, to a lesser extent, through the licensing of our HomeRun technology and the sale of our software products. We sell products through direct sales channels and through distributors. We recognize product revenue when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectibility is probable. Significant management judgements and estimates must be made in connection with the measurement of revenue in a given period. We follow specific and detailed guidelines for determining the timing of revenue recognition. At the time of the transaction, we assess a number of factors including, specific contract and purchase order terms, completion and timing of delivery to the common carrier, past transaction history with the customer, the creditworthiness of the customer, evidence of sell-through to the end user, and current payment terms. Based on the results of the assessment, we may recognize revenue when the products are shipped or defer recognition until evidence of sell-through occurs and cash is received. Revenue from service obligations included in product revenues is deferred and recognized ratably over the period of the obligation. We also maintain accruals and allowances for all cooperative marketing and other programs. Estimated sales returns and warranty costs are based on historical experience and are recorded at the time revenue is recognized. Our products generally carry a one year warranty from the date of purchase.
License and royalty revenues
License and royalty revenue consists of nonrefundable up-front license fees, some of which may offset initial royalty payments, and royalties received by us for products sold by our licensees. Currently, the majority of our license and royalty revenue is comprised of non-refundable license fees paid in advance. Such revenue is recognized ratably over the period during which post-contract customer support is expected to be provided or upon delivery and transfer of agreed upon technical specifications in contracts where essentially no further support obligations exist. Future license and royalty revenue is expected to consist primarily of royalties received by us for products sold by our licensees. We do not expect that such license and royalty revenue will constitute a substantial portion of our revenue in future periods.

27


Software license and post contract support revenues
With the introduction of our IntelliPOP product line, we expect that revenue from the sale of software products and maintenance fees may constitute a substantial portion of revenue in future periods. Currently, our software revenue is derived from two separate sources, software license fees and post-contract maintenance and support fees. The software license fee typically grants a perpetual license to the customer. We generally recognize revenue from the sale of the software license when all criteria for revenue recognition have been met similar to our hardware product sales. The revenue for maintenance and support fees is recognized ratably over the term of the separate support contract.
Should changes in conditions cause us to determine that the criteria for revenue recognition are not met for certain future transactions, revenue recognition for any reporting period could be adversely affected.
Inventories
Inventories are stated at the lower of cost or market. Cost is computed using standard cost, which approximates actual cost on a first-in, first-out basis. We record provisions to write down our inventory and related purchase commitments for estimated obsolescence or unmarketable inventory equal to the difference between the cost of the inventory and the estimated market value based upon assumptions about October 26, 2001. Employees who choosethe future demand and market conditions. If actual future demand or market conditions are less favorable than we estimate, additional inventory provisions may be required.
Allowance for doubtful accounts
We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to cancel options will receive creditmake payments. These estimated allowances are periodically reviewed, analyzing the customers’ payment history and information regarding the customers’ creditworthiness known to us. If the financial condition of any of our customers were to deteriorate, resulting in their inability to make payments, an additional allowance may be required.
Accounting for past vesting as well as vesting duringlong-lived assets
We assess the waiting period beforeimpairment of long-lived assets and related goodwill periodically in accordance with the new options are issued. In addition, the vesting periodprovisions of SFAS No. 121,“Accounting for the new options will be shortened by approximately six months. However,Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of.” An impairment review is performed whenever events or changes in circumstances indicate that the replacement stock options willcarrying value may not be exercisable priorrecoverable. Factors considered important which could trigger an impairment review include, but are not limited to, significant underperformance relative to expected historical or projected future operating results, significant changes in the grant datemanner of use of the acquired assets or the strategy for the overall business, significant negative industry or economic trends, a significant decline in the stock price for a sustained period, and the market capitalization relative to net book value.
When our management determines that the carrying value may not be recoverable based upon the existence of one or more of the above indicators of impairment, any impairment measured is based on or about October 26, 2001. a projected discounted cash flow method using a discount rate commensurate with the risk inherent in our current business model.
During 2001, we did determine certain intangible long-lived assets were impaired and recorded losses accordingly. Future events could cause us to conclude that impairment indicators once again exist. Any resulting impairment loss could have a material adverse impact on our financial condition and results of operations.
Legal contingencies
We are currently involved in certain legal proceedings as discussed in Note 8 of our consolidated financial statements. Because of uncertainties related to both the potential amount and range of loss from the pending

28


litigation, management is unable to make a reasonable estimate of the liability that could result if there is an unfavorable outcome to these legal proceedings. As additional information becomes available, we will assess the potential liability related to this pending litigation and revise our estimates accordingly. Revisions of our estimates of such potential liability could materially impact our results of operations and financial condition.
Recent Accounting Pronouncements
In June 1998, the Financial Accounting Standards Board ("FASB")FASB issued SFAS No. 133, "Accounting“Accounting for Derivative Instruments and Hedging Activities," which establishes accounting and reporting standards for derivative instruments and hedging activities. It requires an entity to recognize all derivatives as either assets or liabilities inon the balance sheet and measure those instruments at fair value. The CompanyWe adopted SFAS No. 133, (asas amended by SFAS No. 138)138, as required by SFAS No. 137, "Deferral“Deferral of the Effective Date of the FASB Statement No. 133," effective January 1, 2001. The Company, toTo date, haswe have not engaged in derivative and hedging activities, and accordingly does not believe that the adoption of SFAS No. 133 willdid not have a material impact on our financial statements.
In May 2000, the financial reportingEmerging Issues Task Force, or EITF, issued EITF Issue No. 00-14, “Accounting for Certain Sales Incentives” which addresses the recognition, measurement and related disclosuresincome statement classification for sales incentives that a vendor voluntarily offers to customers, without charge, which the customer can use in, or exercise as a result of, a single exchange transaction. In June 2001, the EITF issued EITF Issue No. 00-25, “Vendor Income Statement Characterization of Consideration Paid to a Reseller of the Company.Vendor’s Products,” effective for periods beginning after December 15, 2001 which addresses whether consideration from a vendor to a reseller is: (a) an adjustment of the selling prices of the vendor’s products and, therefore, should be deducted from revenue when recognized in the vendor’s statement of operations; or (b) a cost incurred by the vendor for assets or services received from the reseller and, therefore, should be included as a cost or expense when recognized in the vendor’s statement of operations. Upon application of these EITFs, financial statements for prior periods presented for comparative purposes should be reclassified to comply with the income statement display requirements under these Issues. In December 1999,September 2001, the SecuritiesEITF issued EITF Issue No. 01-09, “Accounting for Consideration Given by Vendor to a Customer or a Reseller of the Vendor’s Products,” which is a codification of EITF Issues No. 00-14, No. 00-25 and Exchange Commission ("SEC")No. 00-22 “Accounting for ‘Points’ and Certain Other Time- or Volume-Based Sales Incentive Offers and Offers for Free Products or Services to be Delivered in the Future.” The adoption of these Issues is not expected to have a material impact on our financial statements.
In July 2001, the FASB issued Staff Accounting BulletinSFAS No. 101 ("SAB 101"), "Revenue Recognition142, “Goodwill and Other Intangible Assets,” which addresses financial accounting and reporting for acquired goodwill and other intangible assets and supersedes APB Opinion No. 17, “Intangible Assets.” It addresses how intangible assets that are acquired individually or with a group of other assets, but not those acquired in Financial Statements," which provides guidance on the recognition, presentation, and disclosure of revenuea business combination, should be accounted for in financial statements filed withupon their acquisition. SFAS No. 142 also addresses how goodwill and other intangible assets should be accounted for after they have been initially recognized in the SEC. SAB 101 outlinesfinancial statements. We will adopt SFAS No. 142 effective January 1, 2002. The adoption of SFAS No. 142 is not expected to have a material impact on our financial statements.
On October 3, 2001, the basic criteria that must be metFASB issued SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” SFAS No. 144 supercedes SFAS No. 121 “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to recognize revenueBe Disposed Of.” SFAS No. 144 applies to all long-lived assets, including discontinued operations, and provides guidance for disclosures related to revenue recognition policies. Management evaluated the guidance in SAB 101 and the current interpretations and believes that it has complied with the guidance contained therein. In March 2000, the Financial Accounting Standards Board issued Interpretation No. 44 ("FIN 44") "Accounting for Certain Transactions Involving Stock Compensation, an Interpretation ofconsequently amends APB Opinion No. 25." FIN 44 clarifies30, “Reporting the applicationResults of Opinion No. 25 for (a)Operations, Reporting the definitionEffects of employee for purposes of applying Opinion No. 25, (b) the criteria for determining whether a plan qualifies as a noncompensatory plan, (c) the accounting consequences of various modifications to the termsDisposal of a previously fixed stock optionSegment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions.” SFAS No. 144 develops one accounting model for long-lived assets that are to be disposed of by sale. SFAS No. 144 requires that long-lived assets that are to be disposed of by sale be measured at the lower of book value or award,fair value less cost to sell. Additionally SFAS No. 144 expands the scope of discontinued operations to include all components of an entity with operations that: (a) can be distinguished from the rest of the entity, and (d)(b) will be eliminated from the accounting for an exchangeongoing operations of stock compensation awardsthe entity in a business combination.

Additional Risk Factors Thatthat Could Affect Ourour Operating Results and the Market Price Of Ourof our Stock
We have a history of losses and expect future losses. to continue to incur losses in the future.
We have incurred substantial net losses and experienced negative cash flow for each quarter since our inception. We incurred net losses attributable to common stockholders of $104.3 million, $74.1 million for the fiscal year ended December 31, 2000 and $12.0 million for the fiscal yearyears ended December 31, 1999.2001, 2000 and 1999, respectively. As of December 31, 2000, 24 2001, we had an accumulated deficit of $130.6$234.9 million. We expect that we will continue to incur losses in 2001 and we may incur losses in future periods as well. To achieve or sustain profitability, we must increase sales of our Expresso products, successfully launch our IntelliPOP product, reduce manufacturing costs, sell excess component parts obtained as a result of canceled purchase commitments and successfully introduce enhanced versions of our existing and new products. into fiscal year 2002.
We may never achieve or sustainprofitability and, if we do so, we may not be able to maintain profitability. We have spent substantial amounts of money on the development of our Expresso products, HomeRun and LongRun technology, IntelliPOP productproducts and software products. We intendIn 2001, we reduced our workforce in an effort to continue increasingdecrease certain of our operating expenditures, including our sales and marketing, research and development and general and administrative expenditures. We cannot assure you thatHowever, we willmay not be able to generate a sufficient level of revenue to offset these expenditures, or thatthe current level of expenditures. Additionally, we willmay be ableunable to adjust spending in a timely manner to respond to any unanticipated decline in revenue due to the fact that our expenditures for sales and marketing, research and development, and general and administrative functions are relatively fixed in the short term, relatively fixed.term. Our ability to increase revenue or achieve and maintain profitability in the future will primarily depend on our ability to do the following:
increase the level of sales of our Expresso products, including existing Expresso inventories;
successfully penetrate new markets for our IntelliPOP products;
reduce manufacturing costs;
sell excess component parts obtained as a result of canceled purchase commitments; and
successfully introduce and sell enhanced versions of our existing and new products.
Our operating results may fluctuate significantly, which could cause our Expresso products, successfully launch our IntelliPOP product, reduce manufacturing costs, sell excess component parts obtained as a result of canceled purchase commitments and successfully introduce and sell enhanced versions of our existing products and new products. stock price to decline.
A number of factors could cause our quarterly and annual financial results to be worse than expected, which could result in a decline in our stock price. Our annual and quarterly operating results have fluctuated in the past and may fluctuate significantly in the future as a result of numerous factors, some of which are outside of our control. These factors include: . availability of capital in the network infrastructure industry; . market acceptance of our products; . competitive pressures, including pricing pressures from our partners and competitors; . the timing or cancellation of orders from, or shipments to, existing and new customers; . the timing of new product and service introductions by us, our customers, our partners or our competitors; . variations in our sales or distribution channels; . variations in the mix of products offered by us; . changes in the pricing policies of our suppliers; . the availability and cost of key components; and . the timing of personnel hiring.
availability of capital in the network infrastructure industry;
management of inventory levels;
market acceptance of our products;
competitive pressures, including pricing pressures from our partners and competitors, particularly in light of continued announcements from competitors in recent quarters that they took significant write downs in inventory, which could lead to a general excess of competitive products in the marketplace;
the timing or cancellation of orders from, or shipments to, existing and new customers;
the timing of new product and service introductions by us, our customers, our partners or our competitors;
variations in our sales or distribution channels;
variations in the mix of products that we offer;
changes in the pricing policies of our suppliers;

the availability and cost of key components; and
the timing of personnel hiring.
We anticipate that average selling prices for our products will decrease in the near future due to volume pricing agreements and the need to reduce relatively high levels of inventory.increased competitive price pressures in certain geographical regions. In addition, we may also experience substantial period to periodperiod-to-period fluctuations in future operating results and declines in gross margin as a result of the erosion of average selling prices for high-speed data access products and services due to a number of factors, including increased competition and rapid technological change. Decreasing the average selling prices of our products could cause us to experience decreased revenue despite an increase in the number of units sold. We cannot assure you that we willmay be ableunable to sustain our gross margins, even at the anticipated reduced levels, improve our gross margins by offering new products or increased product functionality or offset future price declines with cost reductions.
As a result of these and other factors, it is possible that in some future period our operating results will be below the expectations of securities analysts and investors. In that event, the trading price of our common stock would likely further decline. 25 Purchases by past customers have decreased dramatically
We are and we must establish a new base of customers. Many of our past customers have been unable to continue to access capitalbe affected by poor general economic conditions that have resulted in significantly reduced sales levels and, are experiencing significantif such adverse economic conditions continue or worsen, our business, operating results and financial difficulties, including bankruptcy. Our 10 largest customers accounted for 72.2%condition could be negatively impacted.
The continued poor economic conditions in the world economy, which became particularly acute after the events surrounding September 11, 2001, and the continued industry-wide downturn in the telecommunications market have affected, and may continue to affect, our sales in the future. As a result, we may experience a material adverse impact on our business, operating results and financial condition. Comparatively lower sales have resulted in operating expenses increasing as a percentage of net salesrevenue for the year ended December 31, 2001 compared to the years ended December 31, 2000 and 62%1999. Although we have taken actions throughout 2001 to create revenue opportunities and reduce operating expenses, a prolonged continuation or worsening of net sales trends that we faced in 2001 may force us to take additional actions and charges in order to reduce our operating expenses. If we are unable to reduce operating expenses at a rate and level consistent with future adverse sales trends or if we incur significant special charges associated with such expense reductions that are disproportionate to sales, our business, operating results and financial condition could be negatively impacted.
We depend on a limited number of large customers for a substantial portion of our revenue during any given period, and the loss of a key customer or loss or delay of a key order could substantially reduce our revenue in a given period.
We derive a significant portion of our revenue in each period from a limited number of customers. Two customers, Kanematsu Computer System Ltd. and RIKEI Corporation, respectively accounted for 19% and 16%, respectively, of our revenue for the year ended December 31, 1999. Trigem Infocomm,2001. Three customers, TriGemm InfoComm, Inc., Reflex Communications, Inc. and Darwin Networks Inc., accounted for 18%, 12% and 11%, respectively, of our net salesrevenue for the year ended December 31, 2000. Two customers, CAIS, Inc. and Rycom CCI, Inc., accounted for 12% and 10%, respectively, of our net salesrevenue for the year ended December 31, 1999. Many of our past customers have limited or, in 1999. We do not expectsome cases, no access to see similar levels of sales, if any, from the majority of these particular customers in 2001.capital and are experiencing significant financial difficulties, including bankruptcy. In order to meet our revenue targets, we must establish acontinue to acquire new customer basecustomers and increase sales to our existing customers who have not beencustomers. In addition, our lead customers in the past. Our strategy of targeting larger, more established customers may result in longer sales cycles and delayed revenue. Sales intoto larger accounts could also result in increased competition from larger and bettermore established competitors. If sales to our largest customers decrease materially below current levels or if we are unable to establish a new base of customers, such decreases or failures could materially and adversely affect our business, results of operations and financial condition.

We are currently engaged in multiple securities class action lawsuits and a lawsuit with one of our suppliers, any of which, if it results in an unfavorable resolution, could adversely affect our business, results of operations or financial condition.
Beginning July 12, 2001, six putative shareholder class action lawsuits were filed in the United States District Court for the Northern District of California against us and certain of our current and former officers and directors. The complaints were filed on behalf of a purported class of people who purchased our stock during the period between July 20, 2000 and January 31, 2001, seeking unspecified damages. The complaints allege that we and certain of our current and former officers and directors made false and misleading statements about our business during the putative class period. Specifically, the complaints allege violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The complaints have been consolidated under the nameIn re Tut Systems, Inc. Securities Litigation,Civil Action No. C-01-2659-JCS. Lead plaintiffs and lead counsel for plaintiffs have been appointed. Plaintiffs filed a consolidated class action complaint on February 4, 2002. We and our current and former officers and directors believe the allegations against us and them are without merit and intend to defend the action vigorously. An unfavorable resolution of this litigation could have a material adverse effect on our business, results of operations, or financial condition.
On August 3, 2001, a complaint,Arrow Electronics, Inc. v. Tut Systems, Inc., Case No. CV 800433, was filed in the Superior Court of the State of California for the County of Santa Clara against us. The Complaint was filed by one of our suppliers and alleges causes of action for breach of contract and for money on common counts. The Complaint seeks damages in the amount of $10.5 million. There has been no discovery to date and no trial has yet been scheduled. We deny liability and intend to defend ourselves vigorously. An unfavorable resolution of this litigation could have a material adverse effect on our business, results of operations, or financial condition.
On October 30, 2001, we and certain of our current and former officers and directors were named as defendants inWhalen v. Tut Systems, Inc. et al., Case No. 01-CV-9563, a purported securities class action lawsuit filed in United States District Court, Southern District of New York. An amended complaint was filed on December 5, 2001. The amended complaint asserts that the prospectuses from our January 29, 1999 initial public offering and our March 23, 2000 secondary offering failed to disclose certain alleged actions by the underwriters for the offerings. The complaint alleges claims against us and certain of our current and former officers and directors under Section 11 of the 1933 Act and alleges claims against certain of our current and former officers and directors under Section 15 of the 1933 Act. The complaints also name as defendants the underwriters for our initial public offering and secondary offering. We and our current and former officers and directors believe the allegations against us and them are without merit and intend to defend the action vigorously. An unfavorable resolution of this litigation could have a material adverse effect on our business, results of operations, or financial condition.
We face substantial risk in launchingintroducing our new IntelliPOP product. products.
We are in the process of launchinglaunched our new IntelliPOP product. Risks5000 series product in the first half of 2001, and recently announced that we intend to launch our IntelliPOP 8000 series product in 2002. We face significant risks associated with the launch of these new products which include, delays in shipping including software bugs, delays in product hardware and software testing, and delays in production build of the product. but are not limited to:
delays in shipping;
software defects;
delays in product hardware and software testing; and
production delays in building the products.

Since the product willproducts include major software components, we plan to sellinclude software maintenance agreements.agreements in the sales of our products. Accordingly, revenue associated with such maintenance agreements will be deferred and recognized over the life of the underlying support.support of the products. The launch of our IntelliPOP productproducts may also cause customers to delay purchases of our existing products. In addition, the introduction of a new, more complex product,products, coupled with a search for larger, more established customers may result in longer sales cycles and delayed revenue. We mustrevenue from the IntelliPOP series of products.

If we do not reduce our inventory, we may be forced to incur charges, which could materially and future purchase commitments. Changes inadversely impact our business, results of operations and financial condition.
We have resulted in the accumulation ofaccumulated a substantial inventory of finished goods and components.components due to poor global economic conditions, which became more acute after the events surrounding September 11, 2001, and the reduction in product demand due to capital funding decreases experienced by several key customers. In addition, announcements of large-scale inventory write downs by competitors indicate that the risk of inexpensive competitive products coming into the marketplace has continued to increase. We have provided for losses related to the cancellation of purchase commitments.commitments and further allowances for excess and obsolete finished goods inventories and related raw materials. However, we must sell existing finished goods inventory and delay or sell finished goods inventory from future purchase commitments as well as sell component inventory resulting from deliveries on already canceled purchase commitments. Failure to decrease current and future inventory and/or to sell component partsdo so may require that we take additional charges related to slow moving or obsolete inventory and components. If we are unable to sell a substantial amount of both the finished goods and the component inventories, our expected cash position throughout the year 2001 will2002 could be negatively impacted. Our ability to attract and retain our personnel may be negatively impacted, by the drop in our stock price. The drop in our stock price has resulted in most of our outstanding employee stock options being "underwater" or priced substantially above current market price. While we currently have an offer out to the majority of our employees to cancel their existing options and have such options reissued at a date at least six months and two days later than the date of cancellation, the effectiveness of such a plan cannot be predicted. Accounting and other regulatory concerns will prevent or limit our ability to issue additional stock options to these employees during the period between cancellation and reissuance. If certain market conditions persist, the attractiveness of our stock option offerings and the success of our employee stock plans may be negatively impacted and as a result diminish our ability to attract and retain qualified personnel. Changes in capital markets may negatively impact our business. Due to recent changes in the capital markets including increased volatility in equity markets and tightening of lending in the credit markets, we believe that we are exposed to a greater risk that customers will alter their 26 payment practices to conserve capital. These changes may lead to increases in outstanding accounts receivable, longer payback periods and increased risk of default. For example, we increased our provisions recorded on past due accounts receivable from several key customers who, during the latter part of the fourth quarter of 2000, experienced a rapid deterioration in their ability to obtain additional capital to fund their business models, declared their inability to make timely payments on their accounts, and, as of the date of this report, have not been able to demonstrate wherewithal to pay their existing account balances. Two of these customers have filed bankruptcy proceedings. These increased risks will be considered when assessing our customers' wherewithal to pay and will likely result in longer revenue deferrals than previously experienced. We also believe that certain of our customers will alter their deployment plans to meet the constraints imposed by changes in the capital markets. If we are not able to increase sales to other customer segments and/or sales are otherwise delayed, we may experience volatility in expected sales growth patterns which would increase the risk of declining sales growth in any particular quarter. Difficulties in forecasting product sales could negatively impact our business. We base our expense levels in part upon our expectations concerning future revenue and these expense levels are relatively fixed in the short-term. Orders for our products, however, may vary from quarter to quarter. In some circumstances, customers may delay purchasing our current products in favor of next-generation products. In addition, our new products are generally subject to technical evaluations that typically last 60 to 90 days, in the case of IntelliPOP, those evaluations may increase to six months. If orders forecasted for a specific customer for a particular quarter do not occur in that quarter, our revenue for that quarter would be reduced. If we have lower revenue in a quarter than expected, we may not be able to reduce our spending in the short- term in response to this shortfall and reduced revenue would have a direct impact on our results of operations for that quarter. Further, we purchase components and contract manufacture our products based on forecasts of sales. If orders for products exceed our forecasts, we may have difficulty meeting customers orders in a timely manner, which could damage our reputation or result in lost sales. Conversely, if orders are less than our forecasts, we may have difficulty in canceling future purchase commitments in a timely manner which may result in greater than expected inventory levels and exposure to losses related to slow moving and obsolete inventory. We depend on contract manufacturers to manufacture all of our products and rely upon them to deliver high-quality products in a timely manner. We do not manufacture our products. We rely on contract manufacturers to assemble, test and package our products. We cannot assure you that these contract manufacturers and suppliers will be able to meet our future requirements for manufactured products, components and subassemblies. Any interruption in the operations of one or more of these contract manufacturers would harm our ability to meet our scheduled product deliveries to customers. We also intend to regularly introduce new products and product enhancements, which will require that we rapidly achieve volume production by coordinating our efforts with those of our suppliers and contract manufacturers. The inability of our contract manufacturers to provide us with adequate supplies of high-quality products or the loss of a current contract manufacturer would cause a delay in our ability to fulfill customer orders while we obtain a replacement manufacturer and would harm our business, operating results and financial condition. In addition, we have canceled certain finished goods and component orders which may have a negative impact on our ability to diversify our product manufacturing across a larger base of contract manufactures. In addition, our inability to accurately forecast the actual demand for our products could result in supply, manufacturing or testing capacity constraints. These constraints could result in delays in the delivery of our products or the loss of existing or potential customers, either of which could harm our business, operating results orof operations and financial condition. We currently purchase all of
If our raw materialsExpresso and components used in our products through our contract manufacturers. Components are purchased pursuant to purchase orders based on forecasts, but neither we nor our contract manufacturers have any guaranteed supply arrangements with these suppliers. The availability of many of these components is dependent in part on our ability to provide our contract manufacturers and their 27 suppliers with accurate forecasts of our future needs. If we or our manufacturers were unable to obtain a sufficient supply of components from current sources, we could experience difficulties in obtaining alternative sources or in altering product designs to use alternative components. Resulting delays and reductions in product shipments could damage customer relationships and could harm our business, financial condition or results of operations. In addition, any increases in component costs that are passed on to our customers could reduce demand for our products. We rely on third parties to test substantially all of our products and a failure to adequately control quality could harm our business. Substantially all of ourIntelliPOP products are assembled and tested by our contract manufacturers. Although we perform random spot testing on manufactured products, we rely on our contract manufacturers for assembly and primary testing of our products. Any quality assurance problems could increasenot accepted in the costs of manufacturing, assembling or testing our products and could harmmarket, our business, financial condition and results of operation. Moreover, defects in products that are not discovered in the quality assurance processoperations could damage customer relationships and result in product returns or liability claims, each of which could harm our business, financial condition and results of operations. We purchase several key components from single or limited sources and could lose sales if these sources fail to fill our needs. We currently purchase all of the raw materials and components used in our products through our contract manufacturers. In procuring components, our contract manufacturers rely on some suppliers that are the sole source of those components, and we are dependent upon supply from these sources to meet our needs. For example, all of the field programmable gate array supplies used in our products are purchased from Xilinx and the switching integrated circuit supplies used in the majority of our products are purchased from Texas Instruments. Our products are also dependent on various sole source offerings from Dallas Semiconductor, Metalink US, Motorola, Flextronics Semiconductor, SaRonix, Siemens and Wind River Systems. If there is any interruption in the supply of any of the key components currently obtained from a single or limited source, obtaining these components from other sources could take a substantial period of time which could cause us to redesign our products or could disrupt our operations and harm our business in any given period. Our market is subject to rapid technological change and if we do not address these changes, our products will become obsolete, harming our business and ability to compete. The markets for high-speed data access products are characterized by rapid technological developments, frequent enhancements to existing products and new product introductions, changes in end user requirements and evolving industry standards. In addition, the market for high-speed data access products is dependent in large part on the increased use of the Internet. Issues concerning the use of the Internet, including security, lost or delayed packets, and quality of service, may negatively affect the development of the market for our products. We cannot assure you that we will be able to respond quickly and effectively to technological change. If we do not address these technological changes and challenges by regularly introducing new products, our product line will become obsolete, which would harm our business, financial condition and results of operations. Our success depends on our ability to continually introduce new products that achieve broad market acceptance. We must also continually improve the performance, features and reliability of our products, particularly in response to competitive product offerings. To remain competitive we need to introduce products in a timely manner that incorporate or are compatible with these new technologies as they emerge. We may have only a limited amount of time to penetrate certain markets and we cannot assure you that we will be successful in 28 achieving widespread acceptance of our products before competitors offer products and services similar or superior to our products. Any delay in product introduction could adversely affect our ability to compete and cause our operating results to be below our expectations or the expectations of public market analysts or investors. In addition, when we announce new products or product enhancements that have the potential to replace or shorten the life cycle of our existing products, customers may defer purchasing our existing products. These actions could harm our operating results by unexpectedly decreasing sales, increasing our inventory levels of older products and exposing us to greater risk of product obsolescence. Our success depends on continued market acceptance of our Expresso products and the successful launch of our IntelliPOP product. harmed.
We must devote a substantial amount of human and capital resources in order to maintain commercial acceptance of our Expresso products and IntelliPOP products and to expand offerings of the Expresso product line and the launch of our IntelliPOP productthese products in the MDU and MCU markets and to further penetrate these markets. Historically, the majority of our Expresso products havehas been sold into the MDU market. Our future success depends on the ability to continue to penetrate this market and to expand our penetration into the MCU market. Our success also depends on our ability to educate existing and potential customers and end usersend-users about the benefits of our Fast Copper technology, including HomeRun and Signature Switch technologies, our LongRun and our IntelliPOP productproducts, and about the development of new products to meet changing and expanding demands of service providers, MTU owners and corporate customers. The success of our Expresso and IntelliPOP products will also depend on the ability of our service provider customers to market and sell high-speed data services to end users. We cannot assure you thatend-users. If our IntelliPOP or our Expresso products willdo not achieve or maintain broad commercial acceptance within the MDU market, MCU market, or in any other marketmarkets we enter. may enter, our business, financial conditions and results of operations could be materially and adversely affected.
The market in which we operate is highly competitive, and we may not be able to compete effectively.
The market for multi-service broadband access systems is intensely competitive, and we expect that this market will become increasingly competitive in the future. Our most immediate competitors include, or are expected to include, Cisco Copper Mountain, ElasticSystems, Inc., Lucent Technologies, Inc., Next Level Communications, Inc., Paradyne Networks, ParadyneInc. and a number of other public and private companies. Many of these competitors are offeringoffer or may offer technologies and services that directly compete with some or all of our high-speed access products and related software products. Also, many of these competitors have continued to announce significant changes in their business plans and operations, some of which, such as major write downs of inventory, could result in lower priced products flooding the market and thus have a negative impact on our ability to sustain our current pricing or to sell current levels of inventory. In addition, the market in which we compete is characterized by increasing consolidation, and we cannot predict with certainty how industry consolidation will affect us or our competitors.
Many of our competitors and potential competitors have substantially greater name recognition and technical, financial and marketing resources than we do, and we can give you no assurance that we will be able to compete effectively in our target markets. These competitors may be able to undertake more extensive marketing campaigns, adopt more aggressive pricing policies and devote substantially more resources to developing new products than we can. In addition, our HomeRun licensees may sell products based on our HomeRun technology to our competitors or potential competitors. This licensing may cause an erosion in the potential market for our products. We cannot assure you that we will have the financial resources, technical expertise or marketing, manufacturing, distribution and support capabilities to compete successfully. This competition could result in

price reductions, reduced profit margins and loss of market share, which could harm our business, financial condition and results of operations.
Our copper-wire based solutions face severe competition from other technologies, and the commercial acceptance of any competing solutions could harm our business and ability to compete. compete and thus materially and adversely impact our business, financial condition and results of operations.
The market for high-speed data access products and services is characterized by several competing technologies, including fiber optic cables, coaxial cables, satellites and other wireless facilities. These competing solutions provide fast access, high reliability and are cost-effective solutions for some users. Because manyMany of our products are based on the use of copper telephone wire, and becausewire. Because there are physical limits to the speed 29 and distance over which data can be transmitted over thiscopper wire, our products may not be a viable solution for customers requiring service at performance levels beyond the current limits of copper telephone wire. To the extent that telecommunications service providers choose to install fiber optic cable or other transmission media in the last mile, or to the extent that homes and businesses install other transmission media within buildings, we expect that demand for our products that are based on copper telephone wires will decline. Commercial acceptance of any one of these competing solutions or any technological advancement or product introduction that provides faster access, greater reliability, increased cost-effectiveness or other advantages over technologies that utilize existing copper telephone copper wires could decrease the demand for our products and reduce average selling prices and gross margins associated with our products. The occurrence of any one or more of these events could harm our business, financial condition and results of operations. Manufacturing or design defects in
If we fail to manage our products could harm our reputation and business. Any defect or deficiency in our products could reduce the functionality, effectiveness or marketability of our products. These defects or deficiencies could cause orders for our products to be canceled or delayed, reduce revenue, or render our product designs obsolete. In that event, we would be required to devote substantial financial and other resources for a significant period of time in order to develop new product designs. We cannot assure you that we would be successful in addressing any manufacturing or design defects in our products or in developing new product designs in a timely manner, if at all. Any of these events, individually or in the aggregate, could harm our business, financial condition and results of operations. Changing industry standards may reduce the demand for our products, which will harm our business. We will not be competitive unless we continually introduce new products and product enhancements that address changing industry standards. The emergence of new industry standards, whether through adoption by official standards committees or widespread use by telephone companies or other service providers, could require redesign of our products. If these standards become widespread and our products are not in compliance, our customers and potential customers may not purchase our products, which would harm our business, financial condition and results of operations. The rapid development of new standards increases the risk that competitors could develop products that make our products obsolete. Any failure by us to develop and introduce new products or enhancements directed at new industry standards could harm our business, financial condition and results of operations. In addition, selection of competing technologies as standards by standards setting bodies such as the HomePNA could negatively affect our reputation in the market regardless of whether our products are standard compliant or demand for our products does not decline. This selection could be interpreted by the press and others as having a negative impact on our business which could negatively impact the market price of our stock. We may not be able to effectively integrate our recent acquisitions into our existing business. In February 2000, we acquired FreeGate, in May 2000, we acquired Xstreamis and in January 2001, we acquired ActiveTelco. We will need to overcome significant issues in order to realize any benefits from these transactions. These issues include: . integrating the operations of the geographically dispersed businesses acquired into our own operations; . incorporating acquired technology, rights and products into our products and services; . developing new products and services that utilize the assets of all entities; . the potential disruption of our ongoing business and the distraction of our management; and . the potential impairment of relationships with employees, suppliers and customers. 30 We may engage in future acquisitions of companies, technologies or products and the failure to integrate any future acquisitions could harm our business. As a part of our business strategy, we expect to make additional acquisitions of, or significant investments in, complementary companies, products or technologies. Any future acquisitions would be accompanied by the risks commonly encountered in acquisitions of companies. These risks include: . difficulties in assimilating the operations and personnel of the acquired companies; . diversion of management's attention from ongoing business concerns; . the potential inability to maximize our financial and strategic position through the successful incorporation of acquired technology and rights into our products and services; . additional expense associated with amortization of acquired intangible assets; . maintenance of uniform standards, controls, procedures and policies; and . impairment of existing relationships with employees, suppliers and customers as a result of the integration of new personnel. We cannot assure you that we will be able to successfully integrate any business, products, technologies or personnel that we may acquire in the future, and our failure to do so could harm our business, operating results and financial condition. Failure to effectively manage operations in light of our changing revenue base, will adversely affect our businessability to increase our revenues and improve our results of operations could be harmed.
Our operations have changed significantly due to volatility in our business. In the past, we have rapidly and significantly expanded our operationsoperations. However, in January 2001, we reduced our workforce by 10%, in April 2001 by an additional 28%, and in October 2001 by 11% in an effort to control overall operating expenses in response to recent declines in and expected slowing of our sales growth. We anticipate that, in the future, expansion in certain areas of our business may be required to address potential growth inexpand our customer base and exploit market opportunities. In particular, we expect to face numerous challenges in the implementation of our business strategy to focus on the larger, more established customers such as ILECs and PTTs in both domestic and international markets. In addition, the volatility in our business has placed a significant strain on our managerial and operational resources. For example, in January 2001 we cut our workforce by 10% in an effort to control overall operating expenses in response to recent declines in and expected slowing of our sales growth.
To exploit the market for our products, we must develop new and enhanced products while implementing and managing effective planning and operating processes. To manage our operations, we must, among other things, continue to implement and improve our operational, financial and management information systems, hire and train additional qualified personnel, continue to expand and upgrade core technologies and effectively manage multiple relationships with various customers, suppliers and other third parties. We cannot assure you that our systems, procedures or controls will be adequate to support our operations or that our management will be able to achieve the rapid execution necessary to exploit fully the market for our products or systems. If we are unable to manage our operations effectively, our business, financial condition and results of operations could be harmed.

We depend on international sales for a significant portion of our revenue, which could subject our business to a number of risks. risks; if we are unable to generate significant international sales, our business, financial condition and results of operations could be materially and adversely affected.
Sales to customers outside of the United States accounted for approximately 56.3%, 41.0%, and 32.3% of revenue for the years ended December 31, 2001 and 2000 and 1999, respectively. There are a number of risks arising from our international business, including: . longer receivables collection periods; . increased exposure to bad debt write-offs; 31 . risk of political and economic instability; . difficulties in enforcing agreements through foreign legal systems; . unexpected changes in regulatory requirements; . import or export licensing requirements; . reduced protection for intellectual property rights in some countries; and . currency fluctuations. including, but not limited to:
longer receivables collection periods;
increased exposure to bad debt write-offs;
risk of political and economic instability;
difficulties in enforcing agreements through foreign legal systems;
unexpected changes in regulatory requirements;
import or export licensing requirements;
reduced protection for intellectual property rights in some countries; and
currency fluctuations.
We expect sales to customers outside of the United States to continue to account for a significant portion of our revenue. However, we can givecannot assure you no assurance that foreign markets for our products will not develop more slowly thanat the rate or to the extent currently anticipated. Any failureIf we fail to increasecontinue to generate significant international sales, to customers outside of the United States could harm our business, financial condition and results of operations. operations could be materially and adversely affected.
We also expend product development and other resources in order to meet regulatory and technical requirements of foreign countries. We are dependingdepend on sales of our products in these foreign markets in order to recoup the costs associated with developing products for these markets.
Our ability to attract and retain our personnel may be impaired by the decrease in our stock price.
The drop in our stock price has resulted in most of our outstanding employee stock options being “under water” or priced substantially above the current market price. In response to the drop in our stock price, on May 14, 2001, we offered our eligible employees the opportunity to tender their existing stock options for cancellation pursuant to a stock option exchange program and have new stock options granted at a date at least six months and two days later than June 8, 2001, the date of cancellation. Accounting and other regulatory concerns prevented or limited our ability to issue additional stock options to these employees during the period between cancellation and the date of the new grant. In the interim, those employees who participated in the stock option exchange offer were granted fewer or, in certain cases, were not granted stock options until December 13, 2001, the date that was six months and two days after the date of such cancellation. Further, employees who did not participate in the stock option exchange offer continue to hold stock options that are priced substantially above the current market price. In both cases, our employees may have felt, and may continue to feel, that they are receiving inadequate compensation. If adverse market conditions persist, the attractiveness of our stock option offerings and the success of our employee stock plans may be negatively impacted and, as a result, diminish our ability to attract and retain qualified personnel.
Our customers may have difficulty meeting their financial obligations to us due to changes in the capital markets, which would reduce our revenue and harm our business.
Due to increased volatility in equity markets and tightening of lending in the credit markets, we believe that we are exposed to a greater risk that customers will alter their payment practices to conserve capital. These changes may lead to increases in our outstanding accounts receivable as a percentage of revenue, extended payback periods and increased risk of default. During the latter part of the fourth quarter of 2000, several key

35


customers experienced a rapid deterioration in their ability to obtain additional capital to fund their businesses. As a result, these customers declared their inability to make timely payments on their accounts and have not been able to demonstrate the ability to pay their existing account balances with us since that time. During 2001, a significant number of these customers commenced bankruptcy proceedings. We factor these increased risks of non-payment into our assessment of our customers’ ability to pay, and these considerations will likely result in longer revenue deferrals than we have previously experienced. We also believe that certain of our customers will alter their plans to deploy products to meet the constraints imposed on them by changes in the capital markets. If we are not able to increase sales in other customer segments, or if our sales are otherwise delayed, our sales growth patterns may become increasingly volatile. This would increase the risk that our sales would decline in any particular quarter and could harm our business, operating results or financial condition.
If we inaccurately estimate customer demand, our business, results of operations and financial condition could be harmed.
We plan our expense levels in part on our expectations about future revenue. These expense levels are relatively fixed in the short-term. However, orders for our products may vary from quarter to quarter. In some circumstances, customers may delay purchasing our current products in favor of next-generation products. In addition, our new products are generally subject to technical evaluations by potential customers that typically last 60 to 90 days. In the case of IntelliPOP, those evaluations may increase to six months. If orders forecasted for a specific customer for a particular quarter are delayed or cancelled, our revenue for that quarter may be less than our forecast. Currently, we have minimal risk of loss associated with long-term customer commitments or penalties for delayed and/or cancelled orders. However, we may be unable to reduce our spending accordingly in the short-term, and any such revenue shortfall would have a direct impact on our results of operations for that quarter. Further, we outsource the manufacturing of our products based on forecasts of sales. If orders for our products exceed our forecasts, we may have difficulty meeting customers’ orders in a timely manner, which could damage our reputation or result in lost sales. Conversely, if our forecasts exceed the order we actually receive and we are unable to cancel future purchase and manufacturing commitments in a timely manner, our inventory levels could increase. This could expose us to losses related to slow moving and obsolete inventory which would have a material adverse effect on our business, operating results and financial condition.
We depend on contract manufacturers to manufacture all of our products and rely on them to deliver high-quality products in a timely manner; the failure of these manufacturers to continue to deliver quality products in a timely manner could have a materially adverse effect on our business, results of operations and financial condition.
We do not manufacture our products. We rely on contract manufacturers to assemble, test and package our products. We cannot assure you that these contract manufacturers and suppliers will be able to meet our future requirements for manufactured products, components and subassemblies. In addition, we believe that current market conditions have placed additional financial strain on our contract manufacturers. Any interruption in the operations of one or more of these contract manufacturers would harm our ability to meet our scheduled product deliveries to customers. We also intend to regularly introduce new products and product enhancements, which will require that we rapidly achieve volume production by coordinating our efforts with those of our suppliers and contract manufacturers. The inability of our contract manufacturers to provide us with adequate supplies of high-quality products or the loss of a current contract manufacturer would cause a delay in our ability to fulfill customer orders while we obtain a replacement manufacturer and would harm our business, operating results and financial condition. In addition, we have canceled certain finished goods and component orders which may harm our relationship with certain contract manufacturers. Moreover, if we do not accurately forecast the actual demand for our products, we may face supply, manufacturing or testing capacity constraints. These constraints could result in delays in the delivery of our products or the loss of existing or potential customers, either of which could harm our business, operating results or financial condition.

36


If our contract manufacturers fail to obtain the raw materials and component products we require in a timely manner, our business could be harmed.
We currently purchase most of our raw materials and components used in our products through our contract manufacturers. Components are purchased pursuant to purchase orders based on forecasts, but neither we nor our contract manufacturers have any guaranteed supply arrangements with these suppliers. The availability of many of these components depends in part on our ability to provide our contract manufacturers and their suppliers with accurate forecasts of our future needs. If we or our manufacturers are unable to obtain a sufficient supply of key components from current sources, we could experience difficulties in obtaining alternative sources at reasonable prices, if at all, or in altering product designs to use alternative components. Resulting delays and reductions in product shipments could damage customer relationships and could harm our business, financial condition or results of operations. In addition, any increases in component costs that are passed on to our customers could reduce demand for our products.
We rely on third parties to test substantially all of our products and our failure to adequately control the quality of our products could harm our business, financial condition and results of operations.
Substantially all of our products are assembled and tested by our contract manufacturers. Although we perform random spot testing on manufactured products, we rely on our contract manufacturers for assembly and primary testing of our products. Any quality assurance problems could increase the cost of manufacturing, assembling or testing our products and could harm our business, financial condition and results of operation. Moreover, defects in products that are not discovered in the quality assurance process could damage customer relationships and result in product returns or liability claims, each of which could harm our business, financial condition and results of operations.
Based on our building specifications, several key components are purchased from single or limited sources and we could lose sales if these sources fail to fill our needs; if we lose sales, our business, financial condition and results of operations could be materially and adversely affected.
We currently purchase most of the raw materials and components used in our products through our contract manufacturers. In procuring components for our products, we and our contract manufacturers rely on some suppliers that are the sole source of those components, and we are dependent upon supplies from these sources to meet our needs. For example, field programmable gate array supplies used in our products are purchased from Xilinx or Altera. We also depend on various sole source offerings from Broadcom, Dallas Semiconductor, Metalink US, Motorola, Flextronics Semiconductor and SaRonix for certain of our products. If there is any interruption in the supply of any of the key components currently obtained from a single or limited source, obtaining these components from other sources could take a substantial period of time which could cause us to redesign our products or could disrupt our operations and harm our business, financial condition and results of operation in any given period.
Our business relies on the continued growth of the Internet and any negative issues associated with the Internet could harm our business.
The market for high-speed data access products depends in large part on the increased use of the Internet. Issues concerning the use of the Internet, including security, lost or delayed packets, and quality of service may negatively affect the development of the market for our products.
Our industry is characterized by rapid technological change and we must continually introduce new products that achieve broad market acceptance in order remain competitive.
The markets for high-speed data access products are characterized by rapid technological developments, frequent enhancements to existing products and new product introductions, changes in end-user requirements and evolving industry standards. To remain competitive, we must continually improve the performance, features and

37


reliability of our products, particularly in response to competitive product offerings. We must introduce products that incorporate or are compatible with these new technologies as they emerge and must do so in a timely manner. We cannot assure you that we will be able to respond quickly and effectively to technological change. We may have only limited time to penetrate certain markets, and we cannot assure you that we will be successful in achieving widespread acceptance of our products before competitors offer products and services similar or superior to our products. Any failure to introduce new products addressing technological changes or any delay in our product introductions could adversely affect our ability to compete and cause our operating results to be below our expectations or the expectations of public market analysts or investors. In addition, when we announce new products or product enhancements that have the potential to replace or shorten the life cycle of our existing products, customers may defer purchasing our existing products. These actions could harm our business, financial condition and operating results by unexpectedly decreasing sales, increasing our inventory levels of older products and exposing us to greater risk of product obsolescence.
Manufacturing or design defects in our products could harm our reputation and our business, financial condition and results of operations.
Any defect or deficiency in our products could reduce the functionality, effectiveness or marketability of our products. These defects or deficiencies could cause orders for our products to be canceled or delayed, reduce revenue, or render our product designs obsolete. In that event, we would be required to devote substantial financial and other resources for a significant period of time to the development of new product designs. We cannot assure you that we would be successful in addressing any manufacturing or design defects in our products or in developing new product designs in a timely manner, if at all. Any of these events, individually or in the aggregate, could harm our business, financial condition and results of operations.
Changing industry standards may reduce the demand for our products, which would harm our business, financial condition and results of operations.
We will not be competitive unless we continually introduce new products and product enhancements that meet constantly changing industry standards. The emergence of new industry standards, whether through adoption by official standards committees or through widespread use of such standards by telephone companies or other service providers, could require the redesign of our products. If these standards become widespread and our products do not comply with these standards, our customers and potential customers may not purchase our products, which would harm our business, financial condition and results of operations. The rapid development of new standards increases the risk that competitors could develop products that make our products obsolete. Any failure by us to develop and introduce new products or enhancements directed at new industry standards could harm our business, financial condition and results of operations. In addition, selection of competing technologies as standards by standards setting bodies such as the HomePNA could negatively affect our reputation in the market, regardless of whether our products are standards-compliant or demand for our products does not decline. This selection could be interpreted by the press and others as having a negative impact on our business which could negatively impact our stock price.
We have in the past and may in the future acquire companies, technologies or products and if we fail to integrate these acquisitions, our business, results of operations and financial condition could be harmed.
In 2001 and 2000, we completed five acquisitions. As a part of our business strategy, we expect to make additional acquisitions of, or significant investments in, complementary companies, products or technologies. We may need to overcome significant issues in order to realize any benefits from our past transactions, and any future acquisitions would be accompanied by similar risks. These risks include, but are not limited to:
difficulties in assimilating the operations and personnel of the acquired companies;
the potential disruption of our ongoing business and the distraction of our management;

38


the potential inability to maximize our financial and strategic position through the successful incorporation of acquired technology and rights into our products and services;
additional expense associated with amortization of acquired intangible assets;
maintenance of uniform standards, controls, procedures and policies; and
impairment of existing relationships with employees, suppliers and customers as a result of the integration of new personnel.
We cannot assure you that we will be able to successfully integrate any business, products, technologies or personnel that we have acquired or may acquire in the future, and our failure to do so could harm our business, operating results and financial condition.
Fluctuations in currency exchange rates may harm our business.
All of our foreign sales are invoiced in U.S. dollars. As a result, fluctuations in currency exchange rates could cause our products to become relatively more expensive for international customers and reduce demand for our products. We anticipate that foreign sales will generally continue to be invoiced in U.S. dollars. Accordingly, we do not currently engage in foreign currency hedging transactions. However, as we expand our current international operations, we may allow payment in foreign currencies and, as a result, our exposure to foreign currency transaction losses may increase. To reduce this exposure, we may purchase forward foreign exchange contracts or use other hedging strategies. However, we cannot assure you that any currency hedging strategy would be successful in avoiding exchange related losses.
If we fail to protect our intellectual property, or if others use our proprietary technology without authorization, our competitive position may suffer.
Our future success and ability to compete is dependentdepends in part upon our proprietary technology. We rely on a combination of copyright, patent, trademark and trade secrets laws and nondisclosure agreements to establish and protect our proprietary technology. We currently hold 2026 United States patents and have 2426 United States patent applications pending. However, we cannot assure you that patents will be issued with respect to pending or future patent applications that we have filed or plan to file or that our patents will be upheld as valid or will prevent the development of competitive products or that any actions we have taken will adequately protect our intellectual property rights.
We generally enter into confidentiality agreements with our employees, consultants, resellers, customers and potential customers, in which we strictly limit access to and distribution of our software, and further limit the disclosure and use of other of our proprietary information. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain or use our products or technology. WeOur competitors may also cannot assure you that our competitors will not independently develop technologies that are substantially equivalent or superior to our technology. In addition, the laws of some foreign countries do not protect our proprietary rights to the same extent as do the laws of the United States.
We may be subject to intellectual property infringement claims that are costly to defend and could harm our business and ability to compete.
Our industry is characterized by vigorous protection and pursuit of intellectual property rights. We are also subject to the risk of adverse claims and litigation alleging infringement of the intellectual property rights of others. We cannot assure you thatFrom time to time, third parties will notmay assert infringement claims in the 32 future with respect to our current or future products. Any such assertion, regardless of its merit, could require us to pay damages or settlement amounts and could require us to develop non-infringing technology or acquire licenses to the technology that is the subject of the asserted infringement. This litigation or potential litigation could result in product delays, increased costs or both. In addition, the cost of any litigation and the resulting distraction of our management resources could harm

39


our business, results of operations or financial condition. We also cannot assure you that any licenses of technology necessary for our business will be available or that, if available, these licenses can be obtained on commercially reasonable terms. Our failure to obtain these licenses could harm our business, results of operations and financial condition.
If our products do not comply with complex government regulations, our products may not be sold, preventing us from increasing our revenue or achieving profitability.
We and our customers are subject to varying degrees of federal, state and local regulation. Our products must comply with various regulations and standards defined by the Federal Communications Commission.Commission, or FCC. The FCC has issued regulations that set installation and equipment standards for communications systems. Our products are also required to meet certain safety requirements. For example, certain of our products must be certified by Underwriters Laboratories in order to meet federal safety requirements relating to electrical appliances to be used inside the home. In addition, certain products must be Network Equipment Building Standard certified before they may be deployed by certain of our customers. Any delay in or failure to obtain these approvals could harm our business, financial condition or results of operations. Outside of the United States, our products are subject to the regulatory requirements of each country in which our products are manufactured or sold. These requirements are likely to vary widely. If we do not obtain timely domestic or foreign regulatory approvals or certificates, we would not be able to sell our products where these regulations apply, which may prevent us from sustaining our revenue or achieving profitability.
In addition, regulation of our customers may adversely impact our business, operating results and financial condition. For example, FCC regulatory policies affecting the availability of data and Internet services and other terms on which telecommunications companies conduct their business may impede our penetration of certain markets. In addition, the increasing demand for communications systems has exerted pressure on regulatory bodies worldwide to adopt new standards, generally following extensive investigation of competing technologies. The delays inherent in this governmental approval process may cause the cancellation, postponement or rescheduling of the installation of communications systems by our customers, which in turn may harm the sale of products by us to these customers. Our success is dependent on
If our ability to providecustomers do not receive adequate and timely customer support. support from us or our third-party providers our relationships with our customers could be damaged, which could harm our business, financial condition and results of operations.
Our ability to achieve our planned sales growth and to retain current and future customers will depend in part uponon the quality of our customer support operations. Our customers generally require significant support and training with respect to our products, particularly in the initial deployment and implementation stage. As our systems and products become more complex, we believe our ability to provide adequate customer support will be increasingly important to our success. Moreover, we believe that our IntelliPOP products will add a significant layer of complexity to the demands on our customer support organizations. We have limited experience with widespread deployment of our products to a diverse customer base, and we cannot assure you that we will have adequate personnel to provide the levels of support that our customers may require during initial product deployment or on an ongoing basis. In addition, we rely on a third party for a substantial portion of our customer support functions, and therefore we believemay have limited control over the level of support that the introduction of IntelliPOP will add a significant layer of complexity to the demands on our customer support organizations.is provided. Our failure to provide sufficient support to our customers could delay or prevent the successful deployment of our products. Failure to provide adequate support could also have an adverse impact on our reputation and relationship with our customers, could prevent us from gaining new customers and could harm our business, financial condition or results of operations. 33

40


If we lose key personnel or are unable to hire additional qualified personnel as necessary, we may not be able to successfully manage our business. business successfully, which could materially and adversely affect our business, financial condition and results of operations.
We depend on the performance of Salvatore D'Auria,D’Auria, our President, Chief Executive Officer, and Chairman of the Board and Secretary, and on other senior management and technical personnel with experience in the data communications, telecommunications and high-speed data access industries. The loss of any one of them could harm our ability to execute our business strategy. Additionally, we do not have employment contracts with any of our executive officers. We believe that our future success will depend in large part upon our continued ability to identify, hire, retain and motivate highly skilled employees who are in great demand. We cannot assure you that we will be able to do so.
Our stock price has fluctuated and is likely to continue to fluctuate, and you may not be able to resell your shares at or above their purchase price.
The trading price of our common stock has been and is likely to continue to be highly volatile. Our stock price could fluctuate widely in response to factors such asincluding, but not limited to, the following: . actual or anticipated variations in operating results; . announcements of technological innovations, new products or new services by us or by our partners, competitors or customers; . changes in financial estimates or recommendations by stock market analysts regarding us or our competitors; . conditions or trends in the telecommunications industry, including regulatory developments; . growth of the Internet; . announcements by us of significant acquisitions, strategic partnerships, joint ventures or capital commitments; . additions or departures of key personnel; . future equity or debt offerings or our announcements of these offerings; and . general market and general economic conditions.
actual or anticipated variations in operating results;
announcements of technological innovations, new products or new services by us or by our partners, competitors or customers;
changes in financial estimates or recommendations by stock market analysts regarding us or our competitors;
conditions or trends in the telecommunications industry, including regulatory developments;
growth of the Internet;
announcements by us of significant acquisitions, strategic partnerships, joint ventures or capital commitments;
additions or departures of key personnel;
future equity or debt offerings or our announcements of these offerings; and
general market and economic conditions.
In addition, in recent years, the stock market in general, and the Nasdaq National Market and the securities of Internet and technology companies in particular, have experienced extreme price and volume fluctuations with severe drops in recent months.drops. These fluctuations have often been unrelated or disproportionate to the operating performance of these technology companies. These market and industry factors may harm our stock price, regardless of our operating results.
Our stock may be delisted from the Nasdaq National Market.
At the closing of the Nasdaq National Market on March 18, 2002, the minimum bid price of a share of our common stock was $1.99. Nasdaq corporate governance rules require that all shares listed on the Nasdaq National Market maintain a minimum bid price at closing of $1.00 per share. Our failure to maintain such a minimum bid price for a period of thirty or more consecutive trading days could result in the Nasdaq governing board taking action to remove our shares from the Nasdaq National Market. Since the second quarter of 2001, the minimum closing bid price of our common stock has dropped below $1.00 per share on a number of occasions, and we cannot assure you that it will not do so again in the future. The delisting of our common stock as well as the threat of delisting of our common stock may negatively impact the value of our shares because shares that trade on the over-the-counter market, rather than the Nasdaq National Market, are typically less liquid and, therefore, trade with larger variations between the bid and asking price.

41


Our charter, bylaws, retention and change of control plans and Delaware law contain provisions that could delay or prevent a change in control.
Certain provisions of our charter and bylaws and our retention and change of control plans, (the "Plans")the “Plans,” may have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from attempting to acquire, control of us. The provisions of the charter and bylaws and the Plans could limit the price that certain investors may be willing to pay in the future for shares of our common stock.stock . Our charter and bylaws provide for a classified board of directors, eliminate cumulative voting in the election of directors, restrict our stockholders from acting by written consent and calling special meetings, and provide for procedures for advance notification of stockholder nominations and proposals. In addition, our board of directors has the authority to issue up to 5,000,000 shares of preferred stock and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without any further vote or action by the stockholders. The issuance of preferred stock, while providing flexibility in connection with 34 possible financings or acquisitions or other corporate purposes, could have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock. The Plans provide for severance payments and accelerated stock option vesting in the event of termination of employment following a change of control. The provisions of the charter and bylaws, and the Plans, as well as Section 203 of the Delaware General Corporation Law, to which we are subject, could discourage potential acquisition proposals, delay or prevent a change of control and prevent changes in our management.
Future sales of our common stock could depress our stock price.
Sales of a substantial number of shares of our common stock in the public market, or the appearance that these shares are available for sale, could harm the market price of our common stock. These sales also may make it more difficult for us to sell equity securities or equity-related securities in the future at a time and price that we deem appropriate. As of December 31, 2000,2001, we had 15,910,79616,411,172 shares outstanding. Of these shares, 15,780,54916,083,641 shares of our common stock are currently available for sale in the public market, some of which are subject to volume and other limitations under securities laws.
Our facilities are located near known earthquake fault zones, and the occurrence of an earthquake or other natural disaster could cause damage to our facilities and equipment which could require us to curtail or cease operations.
Our facilities are located in the San Francisco Bay Area near known earthquake fault zones and are vulnerable to damage from earthquakes. In October 1989, a major earthquake that caused significant property damage and a number of fatalities struck this area. We are also vulnerable to damage from other types of disasters, including fire, floods, power loss, communications failures and similar events. If any disaster were to occur, our ability to operate our business at our facilities could be seriously, or completely, impaired. The insurance we maintain may not be adequate to cover our losses resulting from disasters or other business interruptions.
We rely on a continuous power supply to conduct our operations, and a statewide energy crisis could disrupt our operations and increase our expenses.
In the fourth quarter of 2000 and the first quarter of 2001, California suffered an energy crisis that could have disrupted our operations and increased our expenses. In the event of an acute power shortage which occurs when power reserves for the State of California fall below 1.5%, California has on some occasions implemented, and may in the future implement, rolling blackouts throughout the state. We currently do not have backup generators or alternate sources of power in the event of a blackout, and our current insurance does not provide coverage for any damages we or our customers may suffer as a result of any interruption in our power supply. If California was to suffer a similar energy crisis in the future and blackouts interrupt our power supply, we would be temporarily unable to continue operations at our facilities. Any such interruption in our ability to continue operations at our facilities could damage our reputation, harm our ability to retain existing customers and to

42


obtain new customers, and could result in lost revenue, any of which could substantially harm our business and results of operations.
ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to changes in interest rates primarily from our investments in certain held-to-maturity securities. Under our current policies, we do not use interest rate derivative instruments to manage exposure to interest rate changes. A hypothetical 100 basis point adverse move in interest rates along the entire interest rate yield curve would not materially affect the fair value of interest sensitive financial instruments at December 31, 2000. At December 31, 2000, we held an investment in commercial paper issued by Southern California Edison Company. This investment is included in short-term investments at a carrying value of approximately $9.2 million which matured in January 2001 and is currently in default. We believe that the fair value of this investment has declined since the balance sheet date, however, the ultimate amount of the decline and the net realizable value of this investment is not currently practicably determinable. 2001.
We have no investments, nor are any significant sales, expenses, or other financial items denominated in foreign country currencies. All of our international sales are denominated in USU.S. dollars. An increase in the value of the USU.S. dollar relative to foreign currencies could make our products more expensive and, therefore, reduce the demand for our products. 35

NOTE 1--DESCRIPTION1—DESCRIPTION OF BUSINESS:
Tut Systems, Inc. (the "Company"“Company”), was founded in 1983 and began operations in August 1991. The Company designs, develops and markets advanced communications products whichthat enable high-speed data access over the copper infrastructure of telephone companies, as well as the copper telephone wires in residential and commercial multi-tenant buildings. The Company'sCompany’s products incorporate high-bandwidth access multiplexers, associated modems and routers, ethernet extension products and integrated network management software.
The Company has incurred substantial losses and negative cash flows from operations since inception. For the year ended December 31, 2001, the Company incurred a net loss of $104,326, and negative cash flows from operations of $51,162, and has an accumulated deficit of $234,911 at December 31, 2001. Management expects cash flow from operations to increase during the year, however, to the extent the Company’s business continues to be affected by poor economic conditions impacting the telecommunications industry, the Company will continue to require cash to fund operations. The Company will seek additional funding for operations from alternative debt and equity sources if necessary to maintain reasonable operating levels. The Company cannot be assured that such funding efforts will be successful. Failure to generate positive cash flow in the future could have a material adverse effect on the Company’s ability to achieve its intended business objectives.
NOTE 2--SUMMARY2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
Principles of consolidation
These consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated.
Use of estimates
The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates include valuation of inventories and accounts receivable, estimation of loss on purchase commitments and the recoverability of long-lived assets. Actual results could differ from those estimates. Periodically, the Company reviews all significant investments and assumptions affecting financial statements and, when necessary, records the effect of any adjustments.
Fair value of financial instruments
The fair value of the Company'sCompany’s cash and cash equivalents, short-term investments, accounts receivable and accounts payable and lines of credit approximate their carrying value due to the short maturity or market rate structure of those instruments. The estimated fair values of short-term investments are based on quoted market prices for those securities or similar financial instruments.
Cash, cash equivalents and investments
Cash, cash equivalents and short-term investments are stated at cost or amortized cost, which approximates fair value, and consist of money market funds, commercial paper, US government agency notes certificates of deposits and corporate

bonds. The Company includes in cash and cash equivalents all highly liquid investments which mature within three months of their purchase date. Noncash and noncash equivalents maturing within twelve months from the balance sheet date are classified as short-term investments. Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates that designation as of each balance sheet date. As of December 31, 2000,2001, debt securities were classified as held-to-maturity as the Company intended to, and had the ability to hold these securities to maturity. Held-to-maturity securities are stated at amortized cost, which approximates fair market value.
The Company also has certain othera minority investmentsinvestment in nonpublicly traded companies. These investments area privately-held company. This investment is included in other assets on the Company'sCompany’s balance sheet and generally areis carried at cost. The Company monitors those investmentsthis investment for impairment and makes appropriate reductions in carrying valuesvalue when necessary. 42 TUT SYSTEMS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (in thousands, except per share amounts)
Inventories
Inventories are stated at the lower of cost or market. Cost is computed using standard cost, which approximates actual cost on a first-in, first-out basis. The Company records provisions to write down its inventory and related purchase commitments for estimated obsolescence or unmarketable inventory equal to the difference between the cost of the inventory and the estimated market value based upon assumptions about the future demand and market conditions. If actual future demand or market conditions are less favorable than those estimated by the Company, additional inventory provisions may be required.
Property and equipment
Property and equipment are stated at cost less accumulated depreciation. The Company provides for depreciation by charges to expense which are sufficient to write off the cost of the assets over their estimated useful lives on the straight-line basis. Leasehold improvements are amortized over the lesser of the lease term or the estimated useful life of the improvement. Useful lives by principal classifications are as follows:
Office equipment................................................ equipment5 years
Computers and software.......................................... software3-7 years
Test equipment.................................................. equipment5 years
Leasehold improvements.......................................... improvements1-7 years
When assets are sold or otherwise disposed of, the cost and accumulated depreciation are removed from the asset and allowance for depreciation accounts, respectively. Upon the disposition of property and equipment, the accumulated depreciation is deducted from the original cost and any gain or loss on that sale or disposal is credited or charged to income.
Maintenance, repairs, and minor renewals are charged to expense as incurred. Expenditures which substantially increase an asset'sasset’s useful life are capitalized.

Intangible assets
Intangible assets are stated at cost less amortizationamortization. As of December 31, 2001, intangible assets consisted of completed technology and consistpatents and as of December 31, 2000 intangible assets consisted of goodwill, completed technology and patents, and assembled workforce and workforce. These intangible assets were/are amortized on a straight line basis over the estimated periods of benefit, which are as follows:
Goodwill...........................................................
Goodwill5 years
Completed technology and patents................................... patents5 years
Assembled workforce................................................ workforce3 years
Goodwill representsrepresented the excess of cost over the fair value of the net assets acquired.
Accounting for long-lived assets The Company evaluates the recoverability of its long-lived assets, goodwill related to those assets, and enterprise goodwill in accordance with Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of" ("SFAS 121"). SFAS 121 requires recognition of impairment of long-lived assets upon the occurrence of certain events and in the event that the net book value of such assets exceeds the future undiscounted cash flows attributable to such assets.
The Company assesses the impairment of long-lived assets and related goodwill periodically in accordance with the provisions of SFAS No. 121,Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of.Of. An impairment review is performed whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors considered important which could trigger an impairment review include, but are not limited to, significant underperformance relative to expected historical 43 TUT SYSTEMS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (in thousands, except per share amounts) or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy for the overall business, significant negative industry or economic trends, a significant decline in the stock price for a sustained period, and the market capitalization relative to net book value.
When management determines that the carrying value may not be recoverable based upon the existence of one or more of the above indicators of impairment, any impairment measured is based on a projected discounted cash flow method using a discount rate commensurate with the risk inherent in the Company'sCompany’s current business model.
Revenue recognition
Product revenues
The Company generallygenerates revenue primarily from the sale of hardware products and, to a lesser extent, through the licensing of its HomeRun technology and the sale of its software products. The Company sells products through direct sales channels and through distributors. The Company recognizes product revenue when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectibility is probable. Significant management judgements and estimates must be made in connection with the measurement of revenue in a given period. The Company follows specific and detailed guidelines for determining the timing of revenue recognition. At the time of the transaction, the Company assesses a number of factors including, specific contract and purchase order terms, completion and timing of delivery to the common carrier, past transaction history with the customer, the credit-worthiness of the customer, evidence of sell-through to the end user, and current payment terms. Based on the results of the assessment, the Company may recognize revenue when the products are shipped of defer recognition until evidence of sell-through occurs and cash is received. Revenue from service obligations included in product revenues is deferred and generally recognized ratably over the period of the obligation. The Company also maintains accruals and allowances for all cooperative marketing and other programs. Estimated sales returns and warranty costs are based on historical experience by product,and are recorded at the time revenue is recognized. The Company's products generally carry a one year warranty from the date of purchase.

License and royalty revenues
The Company has entered into non-exclusive technology agreements with various licensees. These agreements provide the licensees the right to use the Company'sCompany’s proprietary technology to manufacture or have products manufactured using the proprietary technology and to receive customer support for specified periods and any changes or improvement to the technology over the term of the agreement.
Contract fees for the services provided under these licensing agreements are generally comprised of license fees and non-refundable, prepaid royalties which are recognized when the proprietary technology is delivered if there are no significant vendor obligations. If the licensing agreements contain post- contractpost-contract customer support, the Company recognizes the contract fees ratably over the five year period during which the post-contract customer support is expected to be provided. This period represents the estimated life of the technology. The Company begins to recognize revenue under the contract, once it has delivered the implementation package which contains all information needed to use the Company'sCompany’s proprietary technology in the licensee'slicensee’s process. The remaining obligations are primarily to provide the licensee with any changes or improvements to the technology and technical advice on specifications, testing, debugging and enhancements.
The Company recognizes royalties upon notification of sale by its licensees. The terms of the royalty agreements generally require licensees to give notification to the Company and to pay royalties within 60 days of the end of the quarter during which the sales take place.
Software license and post contract support revenues
Currently, the Company’s software revenue is derived from two separate sources, software license fees and post-contract maintenance and support fees. The software license fee typically grants a perpetual license to the customer. The Company generally recognizes revenue from the sale of the software license when all criteria for revenue recognition have been met similar to the Company’s hardware product sales. The revenue for maintenance and support fees is recognized ratably over the term of the separate support contract.
Accounting for stock based compensation
The Company accounts for stock-based employee compensation arrangements in accordance with the provisions of Accounting Principles Board ("APB"(“APB”) Opinion No. 25, and "Accounting“Accounting for Stock Issued to Employees," Financial Accounting Standard Board Interpretation No. 44 ("(“FIN 44"44”) "Accounting“Accounting for Certain Transactions Involving Stock Compensation-anCompensation—an Interpretation of APB 25," and complies with the disclosure provisions of SFAS No. 123, "Accounting“Accounting for Stock- BasedStock-Based Compensation." Under APB No. 25, compensation 44 TUT SYSTEMS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (in thousands, except per share amounts) expense is based on the difference, if any, on the date of the grant, between the fair value of the Company'sCompany’s stock and the exercise price. The Company accounts for stock issued to non-employees in accordance with the provisions of SFAS No. 123 and the EITF Issue No. 96-18, "Accounting“Accounting for Equity Instruments that are Issued to other than Employees for Acquiring, or in Conjunction with Selling Goods or Services."
Advertising expenses
The Company accounts for advertising costs as expense in the period in which they are incurred. Advertising expense for the years ended December 31, 2001, 2000 and 1999 was $103, $371 and 1998 was $144, $86 and $127,$260, respectively.

Research and development
Research and development expenditures are charged to expense as incurred.
Income taxes
Deferred income taxes result primarily from temporary differences between financial and tax reporting. Deferred tax assets and liabilities are determined based on the difference between the financial statement bases and the tax bases of assets and liabilities using enacted tax rates. A valuation allowance is established to reduce a deferred tax asset to the amount that is expected more likely than not to be realized.
Foreign currency translation
The functional currency for the Company'sCompany’s foreign subsidiary is the relevant local currency. The translation from foreign currencies to U.S. dollars is performed for balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenue and expense accounts using the weighted average exchange rate during the period. Adjustments resulting from such translation are reflected in comprehensive loss as a separate component of stockholders'stockholders’ equity. Gains or losses resulting from foreign currency transactions are included in the results of operations. 45 TUT SYSTEMS, INC.

Recent accounting pronouncements
In June 1998, the Financial Accounting Standards Board, ("FASB")or FASB, issued Statement of Financial Accounting Standards, SFAS, No. 133, "Accounting“Accounting for Derivative Instruments and Hedging Activities," which establishes accounting and reporting standards for derivative instruments and hedging activities. It requires an entity to recognize all derivatives as either assets or liabilities in the balance sheet and measure those instruments at fair value. The Company adopted SFAS No. 133 (asas amended by SFAS No. 138)138, as required by SFAS No. 137, "Deferral“Deferral of the Effective Date of the FASB Statement No. 133," effective January 1, 2001. TheTo date, the Company to date, has not engaged in derivative and hedging activities, and accordingly does not believe thatactivities. Accordingly the adoption of SFAS No. 133 willdid not have a material impact on the financial reportingstatements.
In May 2000, the Emerging Issues Task Force, or EITF, issued EITF Issue No. 00-14, “Accounting for Certain Sales Incentives”, which addresses the recognition, measurement and related disclosuresincome statement classification for sales incentives that a vendor voluntarily offers to customers, without charge, which the customer can use in, or exercise as a result of, a single exchange transaction. In June 2001, the EITF issued EITF Issue No. 00-25, “Vendor Income Statement Characterization of Consideration Paid to a Reseller of the Company.Vendor’s Products,” effective for periods beginning after December 15, 2001 which addresses whether consideration from a vendor to a reseller is: (a) an adjustment of the selling prices of the vendor’s products and, therefore, should be deducted from revenue when recognized in the vendor’s statement of operations; or (b) a cost incurred by the vendor for assets or services received from the reseller and, therefore, should be included as a cost or expense when recognized in the vendor’s statement of operations. Upon application of these EITFs, financial statements for prior periods presented for comparative purposes should be reclassified to comply with the income statement display requirements under these Issues. In December 1999,September 2001, the SecuritiesEITF issued EITF Issue No. 01-09, “Accounting for Consideration Given by Vendor to a Customer or a Reseller of the Vendor’s Products,” which is a codification of EITF Issues No. 00-14, No. 00-25 and Exchange Commission ("SEC") issued Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition00-22 “Accounting for ‘Points’ and Certain Other Time- or Volume-Based Sales Incentive Offers and Offers for Free Products or Services to be Delivered in Financial Statements," which provides guidancethe Future.” The adoption of these Issues is not expected to have a material impact on the recognition, presentation,Company’s financial statements.
In July 2001, the FASB issued SFAS No. 142, “Goodwill and disclosureOther Intangible Assets,” which addresses financial accounting and reporting for acquired goodwill and other intangible assets and supersedes Accounting Principles Board (“APB”) Opinion No. 17, “Intangible Assets.” It addresses how intangible assets that are acquired individually or with a group of revenueother assets, but not those acquired in a business combination, should be accounted for in financial statements filed withupon their acquisition. SFAS No. 142 also addresses how goodwill and other intangible assets should be accounted for after they have been initially recognized in the SEC. SAB 101 outlines the basic criteria that must be met to recognize revenue and provides guidance for disclosures related to revenue recognition policies. Management evaluated the guidance in SAB 101 and the current interpretations and believes that it has complied with the guidance contained therein. In March 2000, the Financial Accounting Standards Board issued FIN 44. FIN 44 clarifies the application of Opinionfinancial statements. The Company will adopt SFAS No. 25 for (a) the definition of employee for the purposes of applying Opinion No. 25, (b) the criteria for determining whether a plan qualifies as a noncompensatory plan, (c) the accounting consequences of various modifications to the terms of a previously fixed stock option or award, and (d) the accounting for an exchange of stock compensation awards in a business combination. FIN 44 was142 effective JulyJanuary 1, 2000, but certain conclusions covered specific events that occurred after either December 15, 1998, or January 12, 2000.2002.

On October 3, 2001, the FASB issued SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” SFAS No. 144 supercedes SFAS No. 121 “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of.” SFAS No. 144 applies to all long-lived assets, including discontinued operations, and consequently amends APB Opinion No. 30, “Reporting the Results of Operations, Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions.” SFAS No. 144 develops one accounting model for long-lived assets that are to be disposed of by sale. SFAS No. 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 No. 144 expands the scope of discontinued operations to include all components of an entity with operations that: (a) can be distinguished from the rest of the entity, and (b) will be eliminated from the ongoing operations of the entity in a disposal transaction. SFAS No. 144 is effective for the Company for all financial statements issued in 2002. The adoption of SFAS No. 144 is not expected to have a material impact on the Company’s financial statements.

The amount allocated to intangibles was determined based on an appraisal completed by an independent third party using established valuation techniques. The purchased in-process technology was expensed upon acquisition, because technological feasibility had not been established and no future alternative uses existed. The in-process technology percentage of completion was estimated to be 75%. The value of this in-process technology was determined by estimating the costs to develop the purchased in-process technology into a commercially viable product, estimating the resulting net cash flows from the sale of the product resulting from the completion of the in-process technology and discounting the net cash flows back to their present value.

The cost of short-term investments approximated the fair value at December 31, 2000 and 1999. At December 31, 2000, we held an investment in commercial paper issued by Southern California Edison Company. This investment is included in short-term investments at a carrying value of approximately $9.2 million which matured in January 2001 and is currently in default. The Company believes that the fair value of this investment has declined since the balance sheet date, however, the ultimate amount of the decline and the net realizable value of this investment is not currently practicably determinable. NOTE 6--LINES OF CREDIT: The Company entered into a credit facility for up to $7,500 with a lending institution in December 1998. The credit facility was composed of two revolvers: a formula revolver of up to the lesser of $3,000 or 85% of qualifying accounts receivable and a non-formula revolver up to $4,500. The credit facility required a minimum monthly interest payment of $10. The term of the credit facility was eighteen months and was renewable for additional terms of one year unless 60 days' written notice was given by either party. The loans under this credit facility were collateralized by substantially all assets of the Company. This agreement prohibited the payment of dividends. The Company granted the lending institution a warrant to purchase 55 shares of the Company's common stock at an exercise price of $14.00 per share on December 21, 1998. The warrant was exercisable for 5 years from the date of issuance and was valued using the Black-Scholes option pricing model. Amounts outstanding under lines of credit were $1,529 as of December 31, 1999. This credit facility was paid off during fiscal year 2000 and, as a result, there was no amount outstanding under these lines of credit as of December 31, 2000. On December 18, 1999, the lending institution completed a cashless exercise of its warrant to purchase the Company's common stock, resulting in the issuance of 37 shares of common stock. 51 TUT SYSTEMS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (in thousands, except per share amounts) NOTE 7--INCOME TAXES: The income tax provision for $1 for each of 2000, 1999 and 1998 relates to the state minimum franchise tax. The components of net deferred tax assets and liabilities as of December 31, 2000 and 1999 are as follows:

Due to the uncertainty surrounding the realization of the tax attributes in tax returns, the Company has placed a full valuation allowance against its otherwise recognizable net deferred tax assets. At December 31, 2000, the Company has approximately $73,766 in federal and $17,991 in state net operating loss, or NOL, carryforwards to reduce future taxable income. Of these amounts, $28,011 and $12,016 represent federal and state tax deductions, respectively, from stock option compensation. The tax benefit from these deductions will be recorded as an adjustment to additional paid-in capital in the year in which the benefit is realized. At December 31, 2000, the Company also has research and experimentation tax credit carryforwards of approximately $1,424 and $1,133 for federal and state income tax purposes, respectively. The NOL and credit carryforwards expire in 2007 to 2020. NOL and tax credit carryforwards may be subject to annual limitations due to a change in ownership as defined under the Tax Reform Act of 1986. NOTE 8--COMMITMENTS AND CONTINGENCIES: Lease obligations The Company leases office, manufacturing and warehouse space under noncancelable operating leases that expire through 2002. On March 3, 1998, the Company extended its existing lease for its former headquarters location for three years beginning June 1, 1998 to May 31, 2001. In July 2000, the Company subleased this former headquarters location when the Company moved to its new headquarters in Pleasanton, California. In connection with the business combinations in 1999, the Company assumed operating leases which expire in April and December 2001. 52 TUT SYSTEMS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (in thousands, except per share amounts) In July 2000, the Company relocated its principal administrative and engineering facilities from Pleasant Hill, California to Pleasanton, California. The lease for the Pleasanton facility expires April 2007, with an option to renew for five years. Under the terms of the lease agreement, the Company was required to issue a letter of credit in the amount of $1,800. The letter of credit is collateralized by restricted funds in the amount of $3,208, which are included in Intangibles and Other assets. The letter of credit is reduced annually by $250 provided the Company is not in default under the terms of the lease agreement. Minimum future lease payments under operating leases at December 31, 2000 are as follows: 2001............................................................... $ 2,716 2002............................................................... 2,243 2003............................................................... 1,755 2004............................................................... 1,630 2005............................................................... 1,684 Thereafter......................................................... 2,619 ------- $12,647 =======
Rent expense for the years ended December 31, 2000, 1999 and 1998 was $2,165, $369 and $314, respectively. Purchase commitments At December 31, 2000, the Company had noncancellable commitments to purchase finished goods inventory totaling $10,693 in aggregate. Royalty obligation The Company has acquired the rights, title and interests in two patents from a founder and stockholder of the Company. These two patents give the Company exclusive control of the Balun technology required in the Company's products. Under a previous agreement, the Company was required to pay on-going royalties based on the net sales price of products sold utilizing the patented technology. In February 1999, the Company paid the founder $2,500 as a lump sum payment for all its future royalty obligations, which the Company is amortizing ratably over five years. This period represents the estimated life of the patented technology. As of December 31, 2000, the balance of this payment remaining to be amortized was $1,542. Amortization expense for the years ended December 31, 2000 and 1999 was $500 and $458, respectively. For 1998, the royalty fees related to this technology were based on 1% of net sales and totaled approximately $100. Contingencies The Company is subject to legal proceedings, claims and litigation arising in the ordinary course of business. The Company's management does not expect that the ultimate costs to resolve these matters will have a material adverse effect on the Company's consolidated financial position, results of operations, or cash flows. 53 TUT SYSTEMS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (in thousands, except per share amounts) NOTE 9--STOCKHOLDERS' EQUITY Stock split In September 1998, in connection with the Company's reincorporation from California to Delaware, the Company effected a four for one reverse split of its common and preferred stock. All share data and stock option plan information have been restated to reflect the reverse split and the reincorporation. Preferred stock The Company has 5,000 shares of undesignated preferred stock, $0.001 par value, authorized for issuance. The Board of Directors can issue, in one or more series, this preferred stock and fix the voting rights, liquidation preferences, dividend rights, repurchase rights, conversion rights, redemption rights and terms and certain other rights and preferences with stockholder action. There was no preferred stock issued and outstanding at December 31, 2000 or 1999. Warrants for Series G Mandatorily Redeemable Convertible Preferred Stock In connection with the issuance of Series G redeemable convertible preferred stock ("Series G"), in 1998 the Company issued warrants to purchase 667 shares of Series G with an exercise price of $10.00 per share. In January 1999, prior to the public offering, these warrants were exercised, resulting in the issuance of 667 shares of Series G in exchange for cash proceeds totaling $6,700. Simultaneously with the closing of the initial public offering, these Series G redeemable convertible preferred shares were automatically converted into shares of common stock. There were no warrants issued and outstanding at December 31, 2000 or 1999. Initial Public Offering On January 29, 1999, the Company completed its initial public offering of common stock. The Company issued 2,875 shares at $18.00 per share, obtaining net proceeds of approximately $46,900, net of underwriting discounts, commissions and other offering costs. Simultaneously with the closing of the initial public offering, all issued and outstanding shares of the Company's convertible preferred stock and redeemable convertible preferred shares were automatically converted into shares of common stock. Secondary Offering On March 23, 2000, the Company completed its secondary offering of common stock. The Company issued 2,500 shares at $60.00 per share, obtaining net proceeds of approximately $141,700, net of underwriting discounts, commissions and other offering costs. NOTE 10--EQUITY BENEFIT PLANS Stock option plans In November 1993, the Company adopted the 1992 Stock Plan (the "1992 Plan"), under which the Company may grant both incentive stock options and nonstatutory stock options to employees, consultants and directors. Options issued under the 1992 Plan can have an exercise price of no less than 85% of the fair market value, as defined under the 1992 Plan, of the stock at the date of grant. The 1992 Plan, including amendments, allows for the issuance of a maximum of 1,438 shares of the Company's common stock. This number of shares 54 TUT SYSTEMS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (in thousands, except per share amounts) of common stock has been reserved for issuance under the 1992 Plan. At December 31, 2000, the Company is no longer granting stock options from the 1992 Plan. As stock options are terminated or cancelled from the 1992 Plan, the stock options are being retired and are no longer available for future grant. The Company's 1998 Stock Plan (the "1998 Plan") was adopted by the Board of Directors in July 1998 and was approved by the stockholders in September 1998 and has rights and privileges similar to the 1992 Plan. The 1998 Plan allows for the issuance of a maximum of 1,000 shares of the Company's common stock with annual increases starting in 2000, subject to certain limitations. In January 2000, the 1998 Plan was amended to increase the maximum number of shares that may be issued to 1,358. The Company's 1999 Nonstatutory Stock Option Plan (the "1999 Plan") was adopted by the Board of Directors in December 1999. The 1999 Plan allows for the issuance of a maximum of 1,000 shares of the Company's common stock. Additions to the Plan may be approved by the Board of Directors. The 1999 Plan has rights and privileges similar to the 1998 Plan. In April 2000, the 1999 Plan was amended to increase the maximum number of shares that may be issued to 1,425. In October 2000, the 1999 Plan was amended to increase the maximum number of shares that may be issued to 1,825. Generally, stock options are granted with vesting periods of four years and have an expiration date of ten years from the date of grant. However, in the event of a change in control, as defined in our Change in Control plans adopted June 2000, employees who are terminated as a direct result of the change in control will be entitled to certain separation benefits including acceleration of unvested options ranging from six months to full vesting and severance pay ranging from one to eighteen months. Benefits may be limited in certain circumstances due to certain tax code provisions. 55 TUT SYSTEMS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (in thousands, except per share amounts) Activity under the 1992, 1998 and 1999 Plans (the "Plans") are summarized as follows:

In addition to options granted under the Plans, in March 2000, the Company granted an option to purchase 75 shares at $51.25 with rights and privileges similar to the 1998 Plan. In December 2000, the Company granted an option to purchase 65 shares at $7.44 with rights and privileges similar to the 1998 Plan. In addition, during 2000 restricted stock was granted with repurchase rights which lapse over an eighteen month period. The unearned compensation associated with restricted stock grants is amortized on a straight line basis over the eighteen month period. Accordingly, the Company amortized $1,107 for the year ended December 31, 2000. In connection with the grant of options for the purchase of 356 shares of common stock to employees during the period from December 1997 through June 1998, the Company recorded aggregate deferred compensation of $1,820 representing the difference between the deemed fair value of the common stock and the option exercise price at the date of grant. In December 2000, the Company reduced this deferred compensation by $251 to $1,569 before amortization, reflecting employee terminations through December 2000. This deferred compensation will be amortized over the vesting period relating to these options. Accordingly, the Company amortized $438, $455 and $393 for the years ended December 31, 2000, 1999 and 1998, respectively. The Company uses the Black-Scholes option pricing model to value options granted to consultants. The 56 TUT SYSTEMS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (in thousands, except per share amounts) total estimated fair value of these grants during the periods presented was not significant and was expensed over the applicable vesting periods. At December 31, 2000, 1999 and 1998, vested options to purchase 418, 379 and 385 shares of common stock, respectively were unexercised. The weighted average exercise price of these options was $19.92, $1.96 and $0.65 per share for 2000, 1999 and 1998, respectively.

Employee Stock Purchase Plan The Company's 1998 Employee Stock Purchase Plan (the "1998 Purchase Plan") was adopted by the Board of Directors in July 1998 and was approved by the stockholders in September 1998. Under the 1998 Purchase Plan, an eligible employee may purchase shares of common stock from the Company through payroll deductions of up to 15% of his or her compensation, at a price per share equal to 85% of the lesser of the fair market value of the Company's common stock as of the first or last trading day on or after May 1 and November 1 and end on the last trading day of the period six (6) months later. At December 31, 1998, the Company has reserved 250 shares of common stock for issuance under the 1998 Purchase Plan. The 1998 Purchase Plan is subject to annual increases, subject to certain limitations. Pro forma stock-based compensation The Company is required under Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), to disclose pro forma information regarding option grants made to its employees based on specified valuation techniques that produce estimated compensation charges. The following information concerning the Company's stock option plans and employee stock purchase plan is provided in accordance with SFAS 123. The Company accounts for its stock option plans and employee stock purchase plan in accordance with APB No. 25 and related Interpretations. Had compensation expense for the stock option plans and the employee stock purchase plan been determined based on the fair value at the grant date for awards granted in 2000, 1999 and 1998, consistent with the provisions of SFAS 123, the pro forma net loss would have been reported as follows: 57 TUT SYSTEMS, INC.

The Black-Scholes option pricing model was developed for use in estimating fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option pricing models require the input of highly subjective assumptions including the expected stock price volatility. The Company uses projected volatility rates which are based upon historical volatility rates trended into future years. Because the Company's stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimates, in management's opinion, the existing models do not necessarily provide reliable single measure of the fair value of the Company's options. Prior to the Company's initial public offering, the fair value of each option grant was estimated using the minimum value method. Volatility and dividend yields were not factors in the Company's minimum value calculation. Subsequent to the offering, the fair value of each stock option grant has been estimated on the date of the grant using the Black-Scholes option pricing model. The Company has also estimated the fair value of the purchase rights issued from its employee stock purchase plan, using the Black-Scholes option pricing model. The Company first issued purchase rights from the 1998 Purchase Plan in fiscal 1999. The following table outlines the weighted average assumptions for both the stock options granted and the purchase rights issued:
Stock Option Employee Stock Plans Purchase Plan ----------------- ---------------- Year Ended Year Ended December 31, December 31, ----------------- ---------------- 2000 1999 1998 2000 1999 ----- ---- ---- ----- ---- Expected dividend yield..................... 0.0% 0.0% 0.0% 0.0% 0.0% Risk-free interest rate..................... 6.2% 5.6% 5.4% 5.8% 4.7% Expected volatility......................... 120.0% 90.0% 0.0% 120.0% 90.0% Expected life (in years).................... 4.0 4.0 4.0 0.5 0.5
Generally, the Company grants options at a price equal to the fair market value of the Company's stock on the date of the grant. The weighted-average estimated fair values of stock options granted during fiscal 2000, 1999 and 1998 as calculated using the Black-Scholes option pricing model were $31.51, $17.74 and $2.13 per share, respectively. 401(k) Plan In April 1995, the Company adopted the Tut Systems' Inc. 401(k) Plan (the "401(k) Plan") covering all eligible employees. Contributions are limited to 15% of each employee's annual compensation. Contributions to the 401(k) Plan by the Company are discretionary. The Company did not make any contributions for the years ended December 31, 2000, 1999 and 1998. 58 TUT SYSTEMS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (in thousands, except per share amounts) NOTE 11--LOSS ON PURCHASE COMMITMENTS AND ABANDONED PRODUCTS At December 31, 2000, the Company accrued a provison for loss on purchase commitments in the amount of $19,042 related to canceled purchase orders. In addition, the Company recorded a provision for loss on abandoned products of $8,181 related to the Company's decision to abandon the further development and sale of certain product lines. This amount excludes $6,287 already recorded as a provision for excess and obsolete inventory included in the cost of goods sold related to product.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (in thousands, except per share amounts)
The preliminary allocation of the purchase price was based on the estimated fair value of goodwill of $3,248, assembled workforce of $442, and in-process research and development of $1,160. The preliminary amount allocated to intangibles was determined based on an appraisal using established valuation techniques. The purchased in-process technology was expensed upon acquisition because technological feasibility had not been established and no future alternative uses existed. The in-process technology percentage of completion was estimated to be 75%. The value of this in-process technology was determined by estimating the costs to develop the purchased in-process technology into a commercially viable product, estimating the resulting net cash flows from the sale of the product resulting from the completion of the in-process technology and discounting the net cash flows back to their present value. Research and development costs to bring in-process technology from ActiveTelco to technological feasibility are not expected to have a material impact on the Company'sCompany’s future results of operations or cash flows.

The cost of short-term investments approximated the fair value at December 31, 2001 and 2000. During 2001, the Company held an investment in commercial paper issued by Southern California Edison Company. This investment had been included in short-term investments at a carrying value of approximately $9.0 million and matured in January 2001 but was in default. In November 2001, the Company sold this investment for $8.8 million, realizing a loss of $0.2 million. This loss was included in other income (expense), net for 2001.
NOTE 6—RESTRUCTURING COSTS, IMPAIRMENT OF CERTAIN INTANGIBLE ASSETS AND PROVISION FOR INVENTORY:
Restructuring costs
During 2001, the Company recorded $2,311 in restructuring costs and related facility costs in connection with its April 2001 and October 2001 workforce reductions.
In April 2001, the Company announced a restructuring program which included a workforce reduction, closure of excess facilities, and disposal of certain of its fixed assets. As a result of this restructuring program, the Company recorded restructuring costs of $2,092. The restructuring program resulted in the reduction of approximately 28% of the Company’s employees, and the Company recorded a workforce reduction charge of approximately $1,235 relating primarily to severance and fringe benefits. In addition, the number of temporary and contract workers employed by the Company was significantly reduced. The Company recorded costs of restructuring of $785 relating to closure of excess facilities. The closure of excess facilities included the closure of certain satellite facilities due to workforce reductions and the Company’s effort to reduce operating expenses as a result of the restructuring. This cost of restructuring is primarily comprised of non-cancelable lease and operating costs. Other fixed assets retired as a result of the workforce reductions totaled $72. Cash expenditures relating to these workforce reductions were paid in the second quarter of 2001. Amounts related to the closure of excess facilities were accrued in the second quarter of 2001 and will be paid over the respective lease terms through August 2002. As of December 31, 2001, the Company had a remaining accrual of $402, which remains to be paid through August 2002 related to the Sunnyvale facility shut down in the second quarter of 2001.
In October 2001, the Company further reduced its workforce by approximately 11%. The Company recorded a workforce reduction charge of $219. Cash expenditures relating to this workforce reduction were paid in the fourth quarter of 2001.
Impairment of certain intangible assets
The Company recorded impairment charges totaling $32,551 in 2001.
Based on the impairment review performed during the third quarter of 2001, the Company recorded a $29,859 impairment charge to reduce goodwill and other intangible assets. The charge was determined based

TUT SYSTEMS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in thousands, except per share amounts)

upon estimated discounted future cash flows using a discount rate of 20%. The assumptions supporting future cash flows, including the discount rate, were determined using management’s best estimates. The underlying factors contributing to the decline in expected future cash flows include a continued slowdown in the telecommunications market, and more recently, the indefinite postponement of capital expenditures, especially within the hospitality industry.
During the first quarter of 2001, the Company recorded a $2,692 impairment charge relating to completed technology and patents. This resulted from the Company’s decision not to pursue further incorporation of the related OneGate product and other intellectual property acquired from FreeGate into the design of future products.
Provision for inventory
The Company recorded a provision for inventory totaling $18,500 in the first quarter of 2001, related to the costs of raw materials and finished goods in excess of what the Company reasonably expected to sell in the foreseeable future as of the first quarter of 2001. The Company recorded an additional provision for inventory totaling $11,425 during the third quarter of 2001, related to the costs of raw materials and finished goods in excess of revised projections of what the Company reasonably expected to sell in the foreseeable future as of the third quarter of 2001. These revised projections were a result of continued decline in the telecommunications market, and, following the events surrounding September 11, 2001, the indefinite postponement of capital expenditures, especially within the hospitality industry. The Company recorded an additional provision for inventory totaling $4,312 in the fourth quarter of 2001 as a part of our normal business operations and product inventory assessments.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(in thousands, except per share amounts)

Due to the uncertainty surrounding the realization of the tax attributes in tax returns, the Company has placed a full valuation allowance against its otherwise recognizable net deferred tax assets.
At December 31, 2001, the Company has approximately $120,838 in federal and $40,058 in state net operating loss, or NOL, carryforwards to reduce future taxable income. Of these amounts, $28,044 and $12,049 represent federal and state tax deductions, respectively, from stock option compensation. The tax benefit from these deductions will be recorded as an adjustment to additional paid-in capital in the year in which the benefit is realized.
At December 31, 2001, the Company also has research and experimentation tax credit carryforwards of approximately $1,936 and $1,526 for federal and state income tax purposes, respectively. The NOL and credit carryforwards expire in 2002 to 2021.
The Company’s ability to use its federal and state net operating loss carryforwards and federal and state tax credit carryforwards to reduce future taxable income and future taxes, respectively, may be subject to restrictions attributable to equity transactions that may have resulted in a change of ownership as defined by Internal Revenue Code Section 382. In the event the Company has had such a change in ownership, utilization of these carryforwards could be severely restricted and could result in significant amounts of these carryforwards expiring prior to benefiting the Company. The Company is currently assessing whether such a change in ownership has occurred.
NOTE 8—COMMITMENTS AND CONTINGENCIES:
Lease obligations
The Company leases office, manufacturing and warehouse space under noncancelable operating leases that expire in 2006 and 2007. In connection with business combinations in 1999 and 2000, the Company assumed operating leases that expired in December 2001 and another that expires in August 2002.
The lease for the Pleasanton facility expires in April 2007, with an option to renew for five years. Under the terms of the lease agreement, the Company was required to issue a letter of credit in the amount of $1,850. The letter of credit is reduced annually, beginning July 1, 2001, by approximately $250, provided that the Company is not in default under the terms of the lease agreement. Pursuant to these terms, the Company’s letter of credit was reduced from $1,850 to $1,600 in the third quarter of 2001. In the fourth quarter of 2001, the Company entered into a lease for engineering facilities in Bridgewater Township, New Jersey. Under the terms of this lease, the Company was required to issue a letter of credit in the amount of $118. These letters of credit are collateralized by restricted funds in the amount of $1,718, which are included in intangibles and other assets as of December 31, 2001.

Stock option plans
In November 1993, the Company adopted the 1992 Stock Plan (the “1992 Plan”), under which the Company may grant both incentive stock options in return for newand nonstatutory stock options to employees, consultants and directors. Options issued under the 1992 Plan can have an exercise price of no less than 85% of the fair market value, as defined under the 1992 Plan, of the stock at the date of grant. The 1992 Plan, including amendments, allows for the issuance of a maximum of 178 shares of the Company’s common stock. This number of shares of common stock has been reserved for issuance under the 1992 Plan. At December 31, 2001, the Company is no longer granting stock options from the 1992 Plan. As stock options are terminated or cancelled from the 1992 Plan, the stock options are being retired and are no longer available for future grant.
The Company’s 1998 Stock Plan (the “1998 Plan”) was adopted by the Board of Directors in July 1998 and was approved by the stockholders in September 1998 and has rights and privileges similar to the 1992 Plan. The 1998 Plan allows for the issuance of a maximum of 1,000 shares of the Company’s common stock with annual increases starting in 2000, subject to certain limitations. In January 2000, the 1998 Plan was amended to increase the maximum number of shares that may be issued to 1,358.

However, in the event of a change in control, as defined in our Change in Control plans adopted June 2000, employees who are terminated as a direct result of the change in control will be entitled to certain separation benefits including acceleration of unvested options ranging from six months to full vesting and severance pay ranging from one to eighteen months. Benefits may be limited in certain circumstances due to certain tax code provisions.

In addition to options granted under the Plans, in March 2000, the Company granted an option to purchase 75 shares at $51.25 with rights and privileges similar to the 1998 Plan. In December 2000, the Company granted an option to purchase 65 shares at $7.44 with rights and privileges similar to the 1998 Plan.
In addition, during 2001 and 2000 restricted stock was granted with repurchase rights which lapse over an eighteen month period to certain employees as part of the acquisitions of FreeGate, the OneWorld assets and ActiveTelco. The unearned compensation associated with restricted stock grants is amortized on a straight line basis over the eighteen month period.

Employee stock purchase plan
The Company’s 1998 Employee Stock Purchase Plan (the “1998 Purchase Plan”) was adopted by the Board of Directors in July 1998 and was approved by the stockholders in September 1998. Under the 1998 Purchase Plan, an eligible employee may purchase shares of common stock from the Company through payroll deductions of up to 15% of his or her compensation, at a price per share equal to 85% of the lesser of the fair market value of the Company’s common stock as of the first or last trading day on or after May 1 and November 1 and end on the last trading day of the period six (6) months later. In 1998, the Company reserved 250 shares of common stock for issuance under the 1998 Purchase Plan. In 2001, the Company allocated an additional 250 shares of common stock, increasing the number of shares reserved for issuance under the 1998 Purchase Plan to 500 of which 136 have been issued, leaving 364 for future issuances under the 1998 Purchase Plan as of December 31, 2001. The 1998 Purchase Plan is subject to annual increases, subject to certain limitations.

Pro forma stock-based compensation
The Company is required under Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (“SFAS 123”), to disclose pro forma information regarding option grants made to its employees based on specified valuation techniques that produce estimated compensation charges. The following information concerning the Company’s stock option plans and employee stock purchase plan is provided in accordance with SFAS 123. The Company accounts for its stock option plans and employee stock purchase plan in accordance with APB No. 25 and related Interpretations. Had compensation expense for the stock option plans and the employee stock purchase plan been determined based on the fair value at the grant date for awards granted in 2001, 2000 and 1999, consistent with the provisions of SFAS 123, the pro forma net loss would have been reported as follows:

The Black-Scholes option pricing model was developed for use in estimating fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option pricing models require the input of highly subjective assumptions including the expected stock price volatility. The Company uses projected volatility rates which are based upon historical volatility rates trended into future years. Because the Company’s stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimates, in management’s opinion, the existing models do not necessarily provide reliable single measure of the fair value of the Company’s options.
Prior to the Company’s initial public offering, the fair value of each option grant was estimated using the minimum value method. Volatility and dividend yields were not factors in the Company’s minimum value calculation. Subsequent to the offering, the fair value of each stock option grant has been estimated on the date of the grant using the Black-Scholes option pricing model. The Company has also estimated the fair value of the purchase rights issued from its employee stock purchase plan, using the Black-Scholes option pricing model. The Company first issued purchase rights from the 1998 Purchase Plan in fiscal 1999. The following table outlines the weighted average assumptions for both the stock options granted and the purchase rights issued:

Generally, the Company grants options at a price equal to the fair market value of the Company’s stock on the date of the grant. The weighted-average estimated fair values of stock options granted during fiscal 2001, 2000 and 1999 as calculated using the Black-Scholes option pricing model were $1.84, $31.51 and $17.74 per share, respectively.

Effective January 1, 2002, contributions are allowed up to 100% of each employee’s annual compensation, but are still limited by IRS annual contribution limitations, depending on the age of the eligible employee.
