PART I

Item 1. Business.

Overview

     SpectraLink Corporation (“SpectraLink” or the “Company”,“we”, “us” or “our” as applicable) was incorporated in Colorado in April 1990, and reincorporated in Delaware in March 1996. Effective December 23, 1999, SpectraLink incorporated SpectraLink International Corporation in Delaware as a wholly owned subsidiary of SpectraLink. We design, manufacture and sell workplace wireless telephone systems which complement existing telephone systems by providing mobile communications in a building or campus environment. SpectraLink^® wireless telephone systems increase the efficiency of employees by enabling them to remain in telephone contact while moving throughout the workplace. SpectraLink wireless telephone systems use a micro-cellular design and interface directly with a telephone system, such as a public branch exchange (PBX), Centrex, or key/hybrid system. Because all calls are routed through the corporate phone system, there are no airtime charges incurred for our customers when they use their SpectraLink wireless telephone system.

     Our product portfolio consists of two types of product categories differentiated by the wireless technologies implemented into the product: The LinkÔ wireless telephone system (Link WTS) and NetLinkÔ wireless telephones. Link WTS uses a proprietary radio infrastructure in the 902-928 MHz radio band targeted to organizations that require a dedicated wireless voice solution for their on-premises mobile workforce. The NetLink wireless telephone products operate over IEEE 802.11-compliant wireless local area networks (WLANs) in the 2400-2483 MHz frequency band using standards-based Internet Protocol (IP) technology. NetLink products are targeted to organizations that want both a wireless voice and wireless data solution on a single network. We also offer an Open Application Interface (OAI), which enables third-party messaging applications to be integrated with SpectraLink wireless telephones. Examples of these third-party applications are nurse-call systems in hospital wards, inventory system look-ups in retail and warehousing sites, and control systems interactions in industrial and manufacturing facilities.

     We are certified to, and have maintained compliance with the International Standards of Operation (ISO) 9001; 2000 standard granted by the British Standards Institute evidencing our commitment to quality assurance.

Strategy

     Our overall strategy is centered on addressing the communication needs of mobile employees in the workplace. Our customers invest in SpectraLink wireless telephone systems to improve productivity, responsiveness, and mobility. Much of our historical success and future growth is based on opportunities in targeted vertical markets where there is a compelling need for workplace mobility. Longer-term, general workplace telephony market opportunities are expected to develop as enterprises continue to adopt new wireless and telephone networking technologies as businesses come to recognize the flexibility of wireless communications versus traditional wired desk phones. There are three key product attributes that allow us to meet the market need and retain our leadership position in wireless telephone systems: voice quality, durability of our products and integration with existing business telephone system infrastructure.

     We believe that our existing products and services, along with our management team, position us to benefit from these communication trends, exceed the market’s technical product requirements, and continue to play an increasing leadership role in addressing the needs of a mobile workforce. The key elements of our strategy include:

	•	Maximize Penetration of Vertical Markets. We believe that our highest returns will be achieved by focusing our sales and marketing efforts to targeted markets that we believe are largely under-penetrated and offer significant opportunity for growth. We generate approximately 25% of our product sales in the healthcare market and approximately 20% of our product sales in the retail market. We are also targeting new vertical markets including auto dealerships, banking, legal and hospitality. To further realize our strategy, we have added additional sales and marketing personnel to tailor our product and service offerings and create marketing campaigns to these identified markets.
	•	Build on our Strong Relationships with our Distribution Channels. We believe that we are well positioned to be a preferred partner to major business telephony equipment providers due to our neutral approach to customers’ brand and technology choices. Both our product lines, Link and NetLink, interoperate with all major PBX manufacturers as well as all major Wi-Fi access point manufacturers. Our proven expertise and flexibility in meeting original equipment manufacturers (OEM) needs is demonstrated in our extended product and service offerings. We actively manage our OEM, distributor and reseller channels. In 2003, our OEM relationships were limited to Avaya, NEC America and a private label agreement with Inter-Tel. In 2004, we increased our OEM portfolio to include Siemens, Nortel and Alcatel Business Systems. This year, we plan to pursue additional OEM relationships that will enable us to broaden our distribution. Our goal is to provide greater exposure of our products through the reach these partners have with their customers. Because our OEM partners primarily sell our NetLink wireless telephones, if OEM sales increase, we would expect our NetLink revenues to increase.
	•	Continue Product and Application Development Leadership. Our first priority is to promote the value of mobile voice and data in the workplace. We execute this strategy by participating in the continued deployment of voice over internet protocol (VoIP) technologies through sales of our NetLink wireless telephones, and our continued enhancements to our legacy product, the Link WTS. Link WTS enhancements will offer our customers continued tangible return on their investments in their existing network infrastructure. In addition, we have initiated technology and marketing programs with complimentary application providers to enhance our product solutions. We now offer certification programs for third-party text messaging applications under our SpectraLink Certified Messaging Applications Program. We also have a new program to certify Wi-Fi WLAN equipment to support enterprise mobile telephony applications. The SpectraLink VIEW (Voice Interoperability for Enterprise Wireless) Certification Program is designed to ensure interoperability between Wi-Fi telephony client devices and wireless local area network (WLAN) infrastructure. SpectraLink VIEW certified products must meet enterprise-grade performance criteria for voice quality, security, capacity and roaming. Finally, we will continue our active participation in the evolving standards of wireless VoIP via our relationships with the Wi-Fi Alliance and the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards body. The SpectraLink Voice Priority (SVP) quality-of-service (QoS) mechanism is a clear demonstration of our commitment to standards, as SVP has served as the industry’s de facto QoS standard since 1999. Many major access point providers including Cisco Systems, Proxim and Symbol Technologies, have licensed our technology which enable the feature to be implemented in our handsets. Until the Wi-Fi alliance adopts further standards, SVP continues to fill the QoS gap. We also actively participate in the evolving standards of VoIP including being participating members of the Wi-Fi Alliance and the IEEE 802.11 standards body.
	•	Continue Our Focus on Customer Service and Processes. Speed to deployment and reliable performance are critical components to the success of on-premises wireless telephony. Therefore, helping our customers meet their goals defines our own success. We will continue to focus on excellent customer service. We will provide products and services that simplify wireless on-premises telephony installations. We have a team entirely dedicated to supporting customer needs by providing expertise in voice network. This establishes another connection point with our customers, sharing operational plans and outcomes, and provides valuable input and relationship enhancing opportunities. We believe that this effort should enable us to improve revenue generation through improved speed, accuracy and quality and extending our range of service offerings.
	•	Expand International Sales and Operations. We plan to grow and tap into new markets by gaining specific country regulatory approvals and expanding our international sales, marketing and support staff. Our aim is to engage with increasing numbers of OEM’s, public or government-owned telecommunication companies, local distributors, resellers and system integrators to include our products as part of their solutions offering. In order to increase our market penetration, we believe we must dedicate resources on a priority-tiered basis. Accordingly, we plan to raise awareness levels of our products and technologies in additional countries and regions by localizing our marketing materials such as customer case studies, building a base of referral customers, and attending specific trade show events in our targeted vertical markets and regions. To serve the needs of our international markets, we similarly expect to expand our operational infrastructure and services organization. Our long-term goal is for international revenue to be 50% of our total revenue.

Participate in Growth of WLAN Adoption. The majority of all WLAN sales today is comprised of the general enterprise market. The growth of WLAN adoption in the market is principally enabled because WLAN creates efficiencies in the workplace as expansion or relocations are not tethered to existing wiring. In addition, telephony providers are pushing VoIP switches to replace circuit-based switches and global standards are in place which ease the adoption of WLAN technologies. However, our products can be used with either legacy circuit-based switches or VoIP, which broaden our market reach.

Market Background

     A growing number of businesses require a high degree of mobility within the workplace yet still remain accessible by telephone to customers or co-workers. Retailers seek competitive advantage by quickly responding to customers’ requests for information and service from employees dispersed throughout the store. Mobile healthcare workers in clinical settings benefit from real-time communications to efficiently deliver quality healthcare. Manufacturers seek more efficient operations by enabling workers in the factory to solve problems or answer questions more rapidly. Service organizations seek shorter customer hold or response time by allowing immediate communications with those who can solve a problem or answer a question. Information technology, maintenance and other corporate office support personnel are more productive if they remain mobile in the workplace without compromising communications with others. Teachers and school administrators provide students a safer and more effective learning environment with telephone access throughout the campus. Across industries, businesses are recognizing the benefits of wireless communications in the workplace.

     Traditionally, businesses have attempted to maintain communications with mobile, on-premises employees by using overhead paging systems and electronic pagers. These indirect types of communication create delays because access to a wired phone is still needed. Delays are exacerbated in high mobility environments, such as hospitals, manufacturing facilities and distribution centers, where both parties may be mobile and repeated pages are required. Additionally, overhead paging is often difficult to understand and may create disruptive and stressful ambient noise.

     Conventional alternatives to paging include the use of two-way radios, cordless phones and traditional cellular phones, all of which have various limitations. Two-way radios do not provide an adequate link to the wired telephone system. Cordless phones are typically single-cell systems and have a limited calling range. Only a small number of cordless phones can be deployed to avoid interference. Traditional cellular phones often provide inconsistent indoor reception, and unless specifically designed for on-premises use, are not directly interfaced with a company’s telephone system. Therefore, traditional cellular phones do not offer feature-rich benefits of the wired desk phone. In addition, monthly usage fees and airtime charges may make cellular phones prohibitively expensive in many applications.

     Products dedicated to on-premises voice applications first appeared in the 1990s in the unlicensed 902-928 MHz band in North America. These adjunct products attach directly to existing business telephone systems and provide wireless phone extensions for use on the premises. Because these systems are unlicensed, they can be installed or relocated without prior approval from the Federal Communications Commission (FCC). The 902-928 MHz band in North America is set aside for unlicensed products which employ either narrow-band or spread spectrum technology. Because narrow-band technology systems in the 902-928 MHz band must operate at lower power levels than spread spectrum systems, they generally have inferior range and are more susceptible to interference. Multi-cellular wireless business phone systems that provide handoff to adjacent base stations, and systems that restrict wireless phones to a single base station, are available in the 902-928 MHz band. In 1994, the FCC allocated additional spectrum in the 1920-1930 MHz band for unlicensed on-premises wireless voice applications. The products that use this spectrum are commonly referred to as unlicensed personal communications systems (U-PCS).

     Similar products are available throughout Europe and in other regions using the license-free radio standard, Digital Enhanced Cordless Telecommunications (DECT). DECT systems operate in the 1880-1900 MHz band, which is allocated to licensed public cellular providers in North America; therefore, DECT systems cannot be sold in North America without modifications to allow operation in one of the available unlicensed bands such as the 1920-1930 MHz or 2.4 GHz. Recent changes in FCC rules make it easier to modify DECT systems for operating at 1920-1930 MHz, and we anticipate that DECT-based products utilizing this band will be introduced in the U.S. market in 2005. DECT technology is used for both multi-cell business systems and single-cell residential cordless telephones, thereby reaching a larger market and resulting in both higher production volumes and lower end-user costs. However, DECT is not based on standards-based Internet Protocol (IP) packet technology, and is therefore not well suited for enterprise wireless data networking or VoIP integration.

     In 1997, the IEEE approved its 802.11 standard for WLANs operating in the 2400-2483 MHz band. The 802.11 standard specifies the radio interface between a wireless device and a base station or access point, as well as among wireless handsets. The standard allows devices to share a single WLAN infrastructure, including both voice and data devices, thus enabling organizations to provide mobile employees access to both data and voice applications over a single network. We chose to offer products that worked within the IEEE’s 802.11 specifications in order to maximize long-term market opportunity.

SpectraLink Products

     The Link wireless telephone system (Link WTS) operates in the 902-928 MHz band and uses a micro-cellular design

3

consisting of three components: a master control unit, base stations and wireless telephones. A master control unit is installed near the telephone system, or at the Centrex demarcation location. It can interface either directly with the analog ports of the host telephone switching system, or it can connect via a digital interface to certain PBX and key/hybrid systems.

     The master control unit also connects to small radio transceivers called base stations via twisted-pair telephone wiring. The base stations provide the wireless link to a six-ounce wireless telephone with an alphanumeric display. The wireless telephone battery provides up to four hours of talk time or up to 80 hours of stand-by time.

     Each base station supports multiple users and covers a transmission area in excess of 50,000 square feet depending on transmission obstructions present in the building. A call is handed off from one base station to another as a user moves throughout the coverage area. High-density base stations are available to support applications that require a large number of users within an area such as trading floors, support centers and emergency response centers. SpectraLink designed the Link WTS to provide seamless coverage, enabling real-time handoff of an active telephone call as the user roams.

     NetLink wireless telephones operate in the 2400-2483 MHz band and are compatible with the IEEE 802.11b specification for use on 802.11-compliant WLANs. Customers can use a single network for both wireless voice and data applications by adding the NetLink wireless telephones to an existing 802.11b or 802.11g-compliant network provided by a WLAN vendor. The NetLink product line consists of up to three component types: NetLink wireless telephones, a NetLink SpectraLink Voice Priority (SVP) server and NetLink telephony gateways.

     NetLink handsets support either frequency hopping or direct sequence implementations of the 802.11 standard. The direct sequence version is compatible with the 802.11b Wi-Fi standard. NetLink handsets also support the H.323 VoIP standard, and other proprietary VoIP protocols from Alcatel, Avaya, Cisco Systems, Inter-Tel, Mitel, and Nortel. Support for additional VoIP protocols is under development, allowing NetLink wireless telephones to operate with other proprietary and standards-based IP telephony platforms.

     For applications that use traditional PBX or Centrex technologies, NetLink telephony gateways are installed near the PBX or key/hybrid system or at the Centrex demarcation location. NetLink telephony gateways convert a circuit-switched telephone station interface to IP packets on a standard Ethernet interface, allowing calls to connect with NetLink wireless telephones over wireless 802.11 networks. NetLink telephony gateways can either interface directly with the analog ports of the host telephone switching system or can connect via proprietary digital interfaces to certain PBX and key/hybrid systems.

     The NetLink SVP server is a dedicated network appliance used in conjunction with our voice priority technology implemented in WLAN access points. SVP is a voice prioritization mechanism developed by us that improves voice quality on WLANs through the use of packet prioritization and timed delivery of packets. A majority of enterprise WLAN network access point providers have licensed and implemented SVP technology to work with their access points, including: Aruba Wireless Networks, Airespace, Avaya, Chantry Networks, Cisco Systems, Colubris Networks, Enterasys Networks, Extreme Networks, Intermec Technologies, Nortel, Proxim, Strix Systems, Symbol Technologies and Trapeze Networks. We anticipate that a standard WLAN prioritization scheme will be ratified by the 802.11 standards committee in 2005. The 802.11 task group “e”, in which we participate, is working on quality of service (QoS) enhancements to the existing standard. It is likely that implementation of the minimum set of mandatory components of this standard will still require a NetLink SVP server to improve voice quality and system performance. However, implementation of optional components of the standard or proprietary QoS enhancements may allow NetLink wireless telephones to operate without the requirement for a NetLink SVP server.

Technology

     We devote significant planning and resources to development and use of advanced technology. Our focus on technology enables us to meet the requirements for delivery of portability, indoor radio and system performance, high reliability, low cost, and manufacturability. All of our key technologies are incorporated into our Link WTS and/or NetLink wireless telephone portfolios. Our technologies include:

     Spread Spectrum Technology. Spread spectrum is a radio frequency transmission technique in which the transmitted information is spread over a relatively wide bandwidth. The use of spread spectrum technology makes radio signals more immune to interference, reduces the possibility of interference with others, provides privacy against eavesdropping, and improves the quality of voice transmission. While there are many advantages to the spread spectrum technique, it is more complex to implement than more commonly used narrow-band modulation techniques. The Link WTS uses a form of spread spectrum transmission called frequency hopping, a technique that combines an information signal with a radio carrier whose frequency assignment changes rapidly in a pseudo-random manner at the transmitter. The signal resulting from frequency hopping is decoded at the receiving end using the same pseudo-random frequency pattern. The NetLink wireless telephones use either frequency hopping or direct sequence spread spectrum technology. Direct sequence spread spectrum uses a technique whereby a signal is spread over the available band by mixing the signal data with a much higher data-rate pseudo-random data stream. As with frequency hopping spread spectrum, the resulting signal is decoded at the receiving end. The spread spectrum technologies implemented in the NetLink wireless telephones conform with IEEE 802.11 (frequency hopping) and 802.11b (direct sequence) global standards.

4

     Radio Technology. We have designed radio transceivers and digital circuits to implement the complex spread spectrum technique at an economical cost and in a small form factor. Our radio transceiver and digital circuit architectures also minimize power consumption and enhance manufacturability and reliability.

     ASIC Design. Our expertise in digital application specific integrated circuit (ASIC) technology allows our systems to be miniaturized, power-efficient and cost-effective. Our wireless telephone, base station, master control unit, and telephony gateway designs all use ASICs. We expect to develop additional ASICs and to incorporate these devices into future systems.

     Wireless Access Protocols. Combining spread spectrum with a micro-cellular design presents unique challenges compared to single-cell spread spectrum implementations, such as advanced home cordless telephones. To address this, we applied our software design expertise to develop robust networking that allows multiple users to have simultaneous telephone access in a spread spectrum radio environment without interfering with each other. We implemented a sophisticated set of software resources, including micro-coded software, digital signal processing software, network architecture software, telephone switching software and user application software to address many of the unique challenges of the in-building wireless environment. The challenges include interference, multi-path degradation, signal absorption, near/far receiver desensitizing, security, busy-hour capacity demands, and shared operation with other radio systems.

     Call Handoff. Critical to the acceptance of on-premises wireless systems by users accustomed to high-quality telephone performance is a hand-off from cell to cell with virtually no disruptive effect on the call in progress. We developed proprietary software to address the frequent and unpredictable nature of on-premises inter-cell handoffs due to interference, multi-path degradation and interior obstructions. Software in the SpectraLink wireless telephones automatically selects the best cell among available base stations or access points and performs the necessary timing and control to provide generally unnoticeable, seamless handoff.

     Telephone System Integration. When our system connects to the phone system using analog ports, our wireless telephones provide many calling features of a traditional desk phone including transfer, conference calling and hold. When the system digitally interfaces to the phone system, our wireless telephones also support the advanced features of the host phone system such as caller identification or calling party name display and multi-line appearance. Currently, our products support digital interfaces to the following manufacturers’ telephone systems: Avaya, Comdial, Fujitsu, Inter-Tel, Mitel, NEC America, Nortel, Siemens and Toshiba. NetLink wireless telephones also integrate with IP standards-based telephone systems using standard or proprietary protocols. VoIP integration provides similar advanced features as traditional digital integration, but with a packet-based network interface. Currently, we support proprietary VoIP protocols from Alcatel, Avaya, Cisco Systems, Inter-Tel, Mitel, and Nortel.

     Application Interface. The SpectraLink Open Application Interface (OAI) enables our handsets to work in conjunction with text messaging applications. The OAI allows third-party applications to write to the handset’s alphanumeric display, set up calls, and receive user input from the keypad. We have worked with application vendors to develop interfaces for e-mail, in-house paging systems, nurse-call systems, and industrial alarm and control systems.

Sales, Marketing and Customer Support

Sales and Marketing

     We sell and support our systems through direct and indirect channels including distributors and OEMs. This strategy is intended to reduce our dependence on a single sales channel and to permit broad marketing of our products and services.

     Sales. As of January 31, 2005, we had 107 employees in our sales organization. Our indirect sales channels sell a majority of our products and services through resellers, distributors and OEMs. Our direct sales channels sell our products and services to end-user customers and support the indirect sales channels. We have North American sales offices in the metropolitan areas of Atlanta, Austin, Boston, Charlotte, Chicago, Cleveland, Dallas, Denver, Detroit, Indianapolis, Los Angeles, Minneapolis, New York, Philadelphia, Pittsburgh, Portland, Sacramento, San Diego, San Francisco, St. Louis, Tampa, Washington, D.C., West Palm Beach and Ontario, Canada. We also have international offices in Australia and the United Kingdom.

     Resellers. Our products are sold through a number of telecommunications equipment providers and distributors in North America. The resellers include Alltel Communications, Inc., Anixter, Inc., BellSouth Communication Systems, Dukane Corporation, Indyme, Inc., Inter-Tel Integrated Systems, LXE, Black Box, Inc., Perot Systems Corporation, Ronco, SBC Communications, Inc., Scan Source, Inc., doing business as Catalyst Telecom, Siemens Information and Communications Networks, Inc., Sprint/United Management Company, Syntegra, Tel-e Connect Systems (TCS), Tessco Technologies, Inc., Toshiba, Verizon Communications, WAV Inc., and Westcon Group, Inc. The NetLink products are also sold through international distributors, including Anixter Europe Holdings BV, ACAL Nederland bv, Express Data, Dimension Data, Itegra AS, Telindus and Westcon Group European Operations Limited. Each of these companies has a non-exclusive reseller relationship with us. We have not restricted our resellers from selling in the same geographical areas.

     OEMs and Private Labels. We have established OEM agreements with Avaya, Alcatel Business Systems, NEC America, Nortel, Siemens and a private label agreement with Inter-Tel. Through these agreements we manufacture products that are branded as and sold exclusively through the OEM partner and its channels. We also develop support for the OEM partners’ proprietary telephone switch protocols. We do not restrict markets for OEM partners. Each of these companies has a non-exclusive OEM relationship with us and there are no minimum purchase commitments.

     Other Partners. We developed an 802.11-compatible voice prioritization mechanism for the NetLink wireless telephones that can be implemented in 802.11 access points to improve voice quality by reducing packet-queuing delays. A number of WLAN vendors agreed to implement SVP technology, including: Aruba Wireless Networks, Airespace, Avaya, Chantry Networks, Cisco Systems, Colubris Networks, Enterasys Networks, Extreme Networks, Intermec Technologies, Nortel, Proxim, Strix Systems, Symbol Technologies, and Trapeze Networks.

     Prior to 2000, we sold our Link WTS and NetLink products primarily in the United States, Canada and Mexico. In 2000, we began selling our NetLink products in Europe. In 2001, we began selling our NetLink products in Asia-Pacific. In the future, we may consider selling NetLink in other areas of the world that permit 802.11 networks in the 2400-2483 MHz band.

Customer Support and Warranty Coverage

     We operate a customer support department dedicated to planning, installing, repairing, training and maintaining our systems. Customer support personnel are located in Boulder, Colorado; Atlanta, Georgia; Bentonville, Arkansas; Wilkesboro, North Carolina; Chicago, Illinois; Houston, Texas; Los Angeles, California; New York City, New York; San Jose, California and Fleet, Hampshire, United Kingdom. Customer support involvement occurs with customers during early customer contact, the system configuration and installation phases, and the on-going warranty periods as well as any contracted maintenance periods.

     We warrant that all products are free of defects upon delivery. We provide standard warranty coverage at no cost for a limited period of time. After the warranty period, the customer support department sells various levels of support, based on the maintenance level selected by the customer.

Customer Dependence, Geographical and Segment Information

     While we have a diverse customer base, we consider our operations to be conducted in one operating segment. We derive

6

our revenue principally from the sale, installation, and service of wireless on-premises telephone systems. The following table summarizes the sales to different customer types as a percentage of total net sales:

     Our sales to major customers, which individually comprised more than 10% of total net sales for the years ended December 31, 2004, 2003, and 2002, are summarized in Note 6 in the accompanying Notes to the Consolidated Financial Statements.

     We had revenue from international operations of approximately 4.5% for the year ended 2004 and 1% for each of the years ending December 31, 2003 and 2002.

Backlog

     We generally ship systems promptly upon the receipt of an order. Our backlog of orders is generally less than 30 days at any given time. Some of our distributors and larger customers place orders for systems in advance of the scheduled delivery date; however, these orders are subject to rescheduling or cancellation. As a result, we currently do not consider backlog to be a meaningful indicator of future sales.

Competition

     The on-premises wireless telephone system industry is competitive and influenced by the introduction of new products. Traditional PBX telephone switch integration with transcoding gateway technology allows us to connect to digital PBXs in the market which represent a vast majority of the large enterprise PBX lines shipped in the U.S. market. VoIP packet base switches from Cisco Systems and others represent a small portion of the network infrastructure products installed in the market. The competitive factors affecting the market for our systems include product features and functions, frequency band of operation, ease-of-use, quality of support, product quality and performance, price, and the effectiveness of marketing and sales efforts. Most of our competitors have significantly greater financial, technical, research and development, and marketing resources than us. As a result, our competitors may respond more quickly to new or emerging technologies and changes in customer requirements, or may devote greater resources to the development, promotion, sale and support of their products than us. In addition, some purchasers may prefer to buy their wireless telephone systems from a single source provider of telephone systems. Other purchasers may prefer to buy their 802.11 wireless telephone systems from a single source provider of WLANs, such as Cisco Systems, which provides 802.11 wireless network infrastructure and enterprise telephone systems as well as wireless telephones, but is limited due to its inability to interoperate with the traditional PBX equipment. Because we focus on wireless on-premises telephone communications, we cannot serve as the sole source for a complete telephone or data communications systems. There is no assurance that we will be able to compete successfully in the future.

     Our product competition falls into four general categories: multi-user cordless telephone products, unlicensed multi-cell systems, cellular-based systems, and WLAN-based systems. Single-user cordless telephones are not considered competing products because of their low user capacity, limited range, and consumer-grade handset design. This category also includes recently announced handsets designed for use with residential Wi-Fi networks and consumer-focused VoIP services. We also do not regard public cellular or PCS services as competitors because of their lack of integration with enterprise telephone systems, inadequate indoor coverage, and usage-based cost structure.

	•	Multi-user cordless telephone systems allow multiple handsets to operate in the same area without interference on shared or unique base stations. Some of these systems offer limited hand-off capability to a secondary base station for additional coverage. These products are typically sold through consumer electronics channels and are targeted at residential and small office applications.
	•	Unlicensed multi-cell systems are products that offer similar capacity and functions to our Link WTS. They operate on unlicensed radio spectrum with no airtime charges or licensing requirements. Some of these products are integrated into the host PBX system, allowing the wireless system to share some of the PBX common equipment and administration. Unlicensed multi-cell systems are available in North America from Alcatel, Ascom, and NEC America. Similar systems using DECT technology are sold throughout Europe and in several Asian countries. DECT technology is used for both multi-cell business systems and single-cell residential cordless products. DECT systems are available from Alcatel, Ascom, Avaya, Ericsson, Kirk Telecom, Nortel, Philips, Siemens, and several other manufacturers. Recent changes in FCC rules make it easier to modify DECT-based

7

		systems for use in the U.S. operating in the U-PCS band at 1920 – 1930 MHz. We expect that modified DECT-based products will be introduced into the U.S. market in 2005.
	•	Cellular-based systems operate on licensed cellular or PCS frequencies, allowing handsets to be used on both the in-building wireless system and the public cellular or PCS network. These systems utilize a network of active or passive antennas installed throughout a building to provide radio coverage for cellular telephone users. Integration with the enterprise telephone system is addressed by forwarding calls to the cellular network through the telephone system or through an adjunct device.
	•	WLAN-based systems use VoIP technology to carry packetized voice information over a standards-based WLAN. Along with our NetLink wireless telephones, Cisco Systems offers a 802.11 handset product. In addition, Vocera Communications offers a 802.11 communication system that utilizes voice recognition technology. Avaya and NEC America have announced plans to re-sell a dual mode Motorola wireless handset that will support both unlicensed WLAN and licensed public cellular technologies for availability in 2005. Additional WLAN-based handsets have been recently announced targeting users of consumer-targeted VoIP services. These products are being offered at price points that are significantly lower than enterprise-targeted wireless handsets, yet significantly higher than typical consumer cordless phones. Several original design manufacturing (ODM) providers of electronic devices have developed Wi-Fi handsets targeted at consumer and low end enterprise markets.

     We also consider the existing technologies of overhead and electronic paging, two-way radios and cordless telephones to be competitive with our products. To the extent such a system is already in use, a potential customer may not be willing or able to make the investment necessary to replace such a system with our products. In addition, there may be potential customers who choose one of these other technologies because of cost or their belief that their needs do not require the full functions provided by our products.

Patents, Intellectual Property, and Licensing

     We seek to establish and maintain our proprietary rights in our technology and products through the use of patents, copyrights, trademarks, trade secret laws and contractual restrictions, such as confidentiality agreements and licenses.

     We have a program to file applications for and obtain patents and trademarks. We also seek to maintain our trade secrets and confidential information by nondisclosure policies and through the use of appropriate confidentiality agreements. We have obtained a number of patents in the United States. There can be no assurance, however, that the rights thereby obtained can be successfully enforced against competitive products. Although we believe the protection afforded by our patents, copyrights, trademarks, and trade secrets has value, the rapidly changing technology in the networking industry and uncertainties in the legal process make our future success dependent primarily on the innovative skills, technological expertise, and management abilities of our employees rather than on the protection afforded by patent, copyright, trademark, and trade secret laws.

     Many of our products are designed to include software or other intellectual property licensed from third parties. While it may be necessary in the future to seek or renew licenses relating to various aspects of our products, we believe, based upon past experience and standard industry practice, that such licenses generally could be obtained on commercially reasonable terms. Nonetheless, there can be no assurance that the necessary licenses would be available on acceptable terms, if at all. Our inability to obtain certain licenses or other rights or to obtain such licenses or rights on favorable terms, or the need to engage in litigation regarding these matters, could have a material adverse effect on our business, operating results, and financial condition.

     The industry in which we compete is characterized by rapidly changing technology, a large number of patents, and frequent claims and related litigation regarding patent and other intellectual property rights. We may in the future be notified that we are infringing certain patent and/or other intellectual property rights of others. Although there are no such pending lawsuits against us or unresolved notices that we are infringing intellectual property rights of others, there can be no assurance that our patents and other proprietary rights will not be challenged, invalidated, or circumvented; that others will not assert intellectual property rights to technologies that are relevant to us; or that our rights will give us a competitive advantage. In addition, the laws of some foreign countries may not protect our proprietary rights to the same extent as the laws of the United States. The risks associated with patents and intellectual property are more fully discussed in the section of this report entitled “Risk Factors,” including the risk factors entitled “Our ability to protect or enforce our intellectual property rights” “The assertion of intellectual property infringement claims against us,” and “We rely on the availability of third-party licenses.”

Manufacturing

     Our manufacturing operations consist primarily of the fabrication and assembly of components and subassemblies, which are individually tested and integrated into full systems, or shipped as individual items for expansion orders. In order to facilitate initial start-up and manufacturing process improvements, we conduct in-house prototype development and have established pilot line capabilities. We maintain complete in-house materials procurement, assembly, testing and quality control functions. In August 2001, we entered into an agreement with OFFSHORE INTERNATIONAL, INC. (Offshore), as

8

Offshore has an existing contractual relationship with Maquilas Teta Kawi S.A. de C.V., for the furnishing of manufacturing space, labor (primarily for component assembly) and services in Empalme, Sonora, Mexico. We utilize a minimal number of subcontract manufacturers to assemble our components.

     The principal components of our systems are unpopulated printed circuit boards, electronic components, including microprocessors and ASICs, and metal or plastic housings, all of which are purchased from outside vendors. Although alternate suppliers are available for most of the components, qualifying replacement suppliers and receiving components could take several months. Many components are available only from sole source suppliers and embody such suppliers’ proprietary technologies. There is no assurance that any sole source supplier will continue to provide the required components in sufficient quantities with adequate quality and at acceptable prices. We would be adversely affected if a redesign of our subassemblies is necessary to develop alternative suppliers. In certain circumstances, a part will be placed on allocation due to competition for parts commonly used by the telecommunications and computer industries.

     Consequently, we could see a material adverse effect on our operations if demand for our products considerably exceeds what is anticipated by the component manufacturers. We maintain, or require suppliers to at certain times maintain, inventory to allow us to fill customer orders without significant interruption during the period that we believe would be required to obtain alternate supplies of many replacement components. However, there is no assurance that we will have sufficient inventory supply to meet every possible contingency. Any shortage or discontinuation of, or manufacturing defect in, these components would have a material adverse effect on our operations.

     Since May 1997, we have maintained a portion of our manufacturing operations at our corporate headquarters in two of our four leased facilities totaling 52,016 square feet located in Boulder, Colorado. We also leased 4,609 square feet in August 2001, which was expanded to include an additional 4,519 square feet in August 2003, in Empalme, Sonora, Mexico. Since we rely on these manufacturing facilities, a major catastrophe affecting any of these locations could result in a prolonged interruption of our business, with adverse impact on us.

Research and Product Development

     The wireless telecommunications industry is subject to rapid technological changes, frequent new product introductions and enhancements, product obsolescence and changes in end-user requirements. We believe our future success and ability to compete in the on-premises wireless telephone market are largely dependent upon our ability to augment current product lines and develop, introduce and sell new features and products while maintaining technological competitiveness through the advancement of our core technologies.

     As of January 31, 2005, we employed 63 people in support of our research and development activities. Our research and development costs were approximately $8,899,000, $7,759,000 and $6,501,000 in fiscal years 2004, 2003 and 2002, respectively. We expect that research and development expenses will be approximately 10% of net sales for fiscal year 2005. Our inability to introduce in a timely manner new products or enhancements to existing products that contribute to sales could have a material adverse effect on our business and financial condition.

Product Warranties and Service

     We provide warranties against defects in materials and workmanship for products for periods ranging from 90 days to 15 months, but in limited cases up to 18 months. At the time the product is shipped, we establish a provision for estimated costs of providing service under these warranties based on historical warranty experience. As of December 31, 2004 and 2003, accrued warranty costs were $901,000 and $493,000, respectively. Product failure rates, materials usage and service delivery costs incurred in correcting a product failure affect our warranty obligation. Revisions to the estimated warranty liability would be required should actual product failure rates, material usage or service delivery costs differ from our estimates.

Government Regulation

     The wireless communications industry, which is regulated by the FCC in the United States and similar regulatory agencies in other countries, is subject to changing political, economic and regulatory influences. Regulatory changes, including changes in the allocation of available frequency spectrum, could significantly impact our operations.

     The 902-928 MHz Band. In 1985, the FCC permitted the use of spread spectrum technology under its Part 15 Rules in the 902-928 MHz band. Part 15 Rules refer to the section of the FCC regulations that permit the use of radio-based systems without requiring the user to obtain an operating license from the FCC. For this reason, Part 15 Rules permit devices to be deployed expediently without the inherent delays associated with the traditional radio equipment licensing procedure. A significant industry developed around the Part 15 Rules for commercial products. The FCC has certified all of the Link wireless telephone systems for unlicensed operation under Part 15 Rules in this band.

     In the federal regulatory framework, Part 15 spread spectrum systems accorded secondary status in the 902-928 MHz band, which means that their operators must accept interference received, and correct any interference caused to other systems, even if it requires the operator to cease operating in the band. The FCC, in Docket 93-61, modified this status somewhat, establishing a presumption of non-interference in favor of Part 15 devices that meet specific requirements. We believe that our Link wireless telephone system satisfies these requirements. In addition, the Part 15 Rules provide us with additional flexibility to resolve interference under certain circumstances.

     The 1920-1930 MHz Band. In 1994, the FCC designated a 10 MHz segment from 1920-1930 MHz for isochronous wireless systems such as voice communications. Wireless telephone equipment operating in this range falls under Subpart D of the Part 15 Rules. We do not offer a product that uses this band, although several competing products operate in the band. Recent changes to the operational rules for this band make it more attractive for manufacturers of DECT-based systems to modify their DECT systems to allow sales in the U.S.

     The 2400-2483 MHz Band. The FCC permits the use of spread spectrum technology under the Part 15 Rules in the 2400-2483 MHz band. The FCC has certified NetLink wireless telephones for unlicensed operation under Part 15 Rules in this band.

     In 1997, the IEEE approved an 802.11 specification for a WLAN standard operating in the 2400-2483 MHz band. The 802.11 standard specified an “over the air” interface between a wireless client and a base station or access point, as well as among wireless clients. The standard provides interoperability among devices sharing a single WLAN infrastructure, including both voice and data devices, thus enabling organizations to provide mobile employees access to both data and voice applications over a single network. Subsequently, a significant industry developed around WLANs in this band. The 802.11 specification is a global standard. Each country that supports the standard also has specific certification processes that must be undergone before a product can operate in that country. We are involved in a number of international certification processes.

Employees

     As of January 31, 2005, we employed 358 persons, 352 of whom were full-time employees.

Item 2. Description of Property.

     Our corporate headquarters, manufacturing, and research and development activities are located in Boulder, Colorado, in one 37,050 square foot leased building at 5755 Central Avenue, 15,083 square feet of office space at 5744 Central Avenue, 14,966 square feet of distribution and office space at 5766 Central Avenue and 7,055 square feet of office space at 2545 Central Avenue. In addition, we lease 9,128 square feet of manufacturing space primarily for component assembly in Empalme, Sonora, Mexico. The length of these leases is as follows: (i) the lease for the 5755 Central Avenue facility runs through April 2007, (ii) the lease for the 5744 Central Avenue facility runs through April 2007, (iii) the lease

10

for 7,483 square feet of the 5766 Central Avenue facility runs through April 2007 and 7,483 square feet of the 5766 Central Avenue facility runs through June 2007, (iv) the lease for the 2545 Central Avenue facility runs through September 2007, and (v) the lease for the Empalme, Sonora, Mexico facility runs through August 2005. We enter into short-term leases for our domestic and international sales offices. We believe that the combination of our existing facilities together with the availability of additional space for lease in Boulder and other real estate markets will be adequate to meet our current and foreseeable facilities needs.

Item 3. Legal Proceedings.

     Two derivative lawsuits were filed in February 2002, each of which related to the now-settled consolidated class action securities lawsuits that are summarized in Note 5 in the accompanying Notes to the Consolidated Financial Statements: Evie Elennis, derivatively on behalf of SpectraLink Corporation, Plaintiff(s), v. Bruce M. Holland, Anthony V. Carollo, Jr., Gary L. Bliss, Michael P. Cronin, Nancy K. Hamilton and John H. Elms, Defendants), and SpectraLink Corporation, Nominal Defendant (United States District Court Civil Action Number 02-D-0345); and Roger Humphreys, Derivatively on Behalf of Nominal Defendant SpectraLink Corporation, Plaintiff, v. Carl D. Carman, Anthony V. Carollo, Jr., Bruce M. Holland, Burton J. McMurtry, Gary L. Bliss, Michael P. Cronin, John H. Elms, and Nancy K. Hamilton, Defendants (Colorado District Court Case No. 02CV1687). In these cases, the plaintiffs allege that the officers and directors of SpectraLink violated fiduciary duties owed to SpectraLink and its stockholders under state laws by allowing and/or facilitating the issuance of alleged public misstatements and omissions, misappropriating nonpublic information for their own benefit, making insider stock sales, wasting corporate assets, abusing their positions of control, and mismanaging the corporation. The plaintiffs in these derivative cases allege that SpectraLink has and will continue to suffer injury as a result of these alleged violations of duty for which the officers and directors should be liable.

     The two derivative actions were stayed pending resolution of the motion to dismiss in the consolidated class action securities litigation, and plaintiff’s counsel in the Elennis derivative action filed an unopposed motion for relief from the stay and filed an amended complaint and then a corrected amended complaint. Prior to the entry of the stays in each of the derivative cases, the defendants had filed motions to dismiss. In August of 2003, Defendants moved to dismiss the amended and corrected Elennis complaint. The Court denied that motion on March 22, 2004. No discovery has been conducted in either of the derivative actions. The defendants in the derivative actions engaged in settlement discussions with the derivative plaintiffs in light of the settlement of the class action securities litigation, and the parties have reached an agreement in principle settling both derivative cases, and consolidating the Colorado state court action with the federal action for purposes of settlement. The settlement acknowledges certain corporate governance changes made by the Company since February of 2002, and calls for an award of attorneys’ fees and expenses of up to $100,000, to be paid by the Company’s directors and officers’ insurance carrier. The settlement is conditioned upon court approval. The United States District Court for the District of Colorado has scheduled a hearing for March 23, 2005, to determine whether the proposed settlement should be approved by the Court as fair, reasonable, and adequate, and to consider the application of plaintiffs’ counsel for attorneys’ fees and expenses.

     We believe these cases are without merit and intend to vigorously defend ourselves if the settlement of the two derivative cases is not effectuated. The Company does not believe that its interests and that of the named officers and directors are adverse to each other as of this time. However, if the settlement is not consummated, no assurance can be given that the Company will be successful in defending the claims being asserted in these suits, or that the interests of the various parties will remain aligned. In addition, the derivative litigation could result in substantial costs, divert management’s attention and resources, or ultimately result in the interests of SpectraLink becoming adverse to those of certain of its officers and directors. In either case, the Company’s business could be adversely affected, even if the plaintiffs are not successful in their claims.

     The Company incurred a loss related to the directors and officers’ insurance deductible of which the majority of the expense was reflected in 2002. As noted, in Note 5 in the accompanying Note to the Consolidated Financial Statements, the settlement of the consolidated class action securities lawsuits was funded by insurance proceeds. Based on current facts and circumstances, the Company is unable to estimate future losses, if any, it may incur if the remaining cases are not settled, after considering the amounts that will be covered by insurance.

     We are not presently a party to any other material pending legal proceedings of which we are aware.

Item 4. Submission of Matters to a Vote of Security Holders.

     No matters were submitted to a vote of our stockholders during the fourth quarter of 2004.

Equity Compensation Plan Information

Stock Option Plan

     On May 24, 2000, our stockholders approved the 2000 Stock Option Plan (the 2000 Option Plan), which is a successor to our original option plan that became effective June 7, 1990. Collectively, these two option plans are referred to as the (Plans). The 2000 Option Plan provides selected employees, officers, directors, agents, consultants and independent contractors options to purchase up to 2,000,000 shares of our common stock. The 2000 Option Plan also provides for automatic annual increases in the number of shares available for issuance under the 2000 Option Plan by an amount equal to five percent of the total number of shares of our common stock outstanding on the last day of the immediately preceding fiscal year, or such lesser number of shares ratified by our Board of Directors, not to exceed 1,300,000 shares. In 2003, the Board of Directors restricted the increase in the number of shares available for issuance under the 2000 Option Plan to 950,000 shares. The Board of Directors did not increase the number of shares for issuance under the 2000 Option Plan in 2004.

     On January 31, 2005, we had approximately 110 stockholders of record.
