OVERVIEW PCTEL, Inc. ("PCTEL", the "company", or "we") provides wireless connectivity products and technology to wireless carriers, aggregators of Internet connectivity, wireless Internet service providers (WISP's), PC OEM's, and wireless equipment manufacturers. The company brings together expertise in RF platform design, mobility software, and hardware. The company's products simplify mobility, provide wireless intelligence, and enhance wireless performance. Additionally, the company licenses both patented and proprietary access technology, principally related to analog modems, to modem solution providers. PCTEL is focused on growing wireless revenue and maximizing the monetary value of its intellectual property. The company operates in four separate product segments: Antenna Products Group (APG), RF Solutions Group (RFSG), Mobility Solutions Group (MSG), and Licensing. PCTEL was incorporated in California in 1994 and reincorporated in Delaware in 1998. The principal executive offices are located at 8725 W. Higgins Road, Suite 400, Chicago, Illinois 60631. The telephone number at that address is (773) 243-3000 and the web site is www.pctel.com. The contents of the web site are not incorporated by reference into this Annual Report on Form 10-K. Antenna Products Group The Antenna Products Group (APG) product line consists of wireless communication antennas designed to enhance the performance of broadband wireless, in-building wireless, wireless Internet service providers and Land Mobile Radio (LMR) applications. The Antenna Products Group was formed around the business of MAXRAD, Inc, which was acquired in January 2004. As a result of the October 2004 acquisition of certain antenna product lines from Andrew Corporation ("Andrew"), APG expanded the product line to include GPS (Global Positioning Systems), satellite communications (Mobile SATCOM) and on-glass mobile antennas. In July 2005, the company again expanded the product line with the purchase of Sigma Wireless Technologies Limited ("Sigma" or "SWT"), located in Dublin, Ireland. Sigma provides integrated variable electrical tilt base stations antennas (iVET), Public Mobile Radio (PMR), and Digital Public Mobile Radio (DPMR) antenna products. APG products are sold to end user customers and dealers through distributors and via direct sales channels to wireless carriers and equipment manufacturers. The products are sold under the MAXRAD, Antenna Specialists(R), Micro-Pulse, and iVET brands. Revenue growth in this segment is tied to emerging wireless applications in broadband wireless, in-building wireless, wireless Internet service providers, GPS and Mobile SATCOM. The LMR, PMR, DPMR, and on-glass mobile antenna applications represent mature markets. A critical factor for revenue growth is the successful absorption of Sigma Wireless Technologies Limited ("Sigma") acquired in July 2005. There are many competitors for the APG product line, as the market is highly fragmented. Competitors include such names as Cushcraft, Mobile Mark, Radiall/Larsen, Comtelco, Wilson, Antennex, Andrew Corporation, and Kathrein. APG seeks out product applications that command a premium for product performance and customer service, and seeks to avoid product applications characterized by commoditization. 1

RF Solutions Group The RF Solutions Group (RFSG) product line consists of software-defined radio products designed to measure and monitor cellular networks. The RF Solutions Group was formed around the business of DTI, Inc., which was acquired in March 2003. The RFSG products represent a cost effective solution for simplifying wireless intelligence. The technology is sold in three forms; as OEM radio frequency receivers or as integrated systems solutions, and as components to U.S. government agencies. The SeeGull(TM) family of OEM receivers collects and measure RF data, such as signal strength and base station identification in order to analyze wireless signals. The CLARIFY(TM) product line is a receiver system solution that uses patent pending technology to identify and measure wireless network interference. Customers of RFSG products are wireless network operators, wireless infrastructure suppliers, and wireless test and measurement solution providers. The company offers derivatives of the SeeGull(TM) and CLARIFY(TM) products for government security applications to prime contractors that hold the necessary security clearances. Revenue in this segment is tied to the deployment of new wireless technology, such as 2.5G and 3G, and the need for existing wireless networks to be tuned and reconfigured on a regular basis. Revenue in this market follows the seasonal capital spending patterns of the large wireless network operators. Revenue for RFSG within each fiscal year is historically seasonal, with a trend of the first quarter being the lowest and each succeeding quarter being higher. Competitors for the RFSG product family are OEM's such as Agilent Technologies, Rohde and Schwarz, Anritsu, Panasonic, and Berkley Varitronics. The RFSG products compete on the basis of product performance at a price point that is generally lower than the competition. Mobility Solutions Group The Mobility Solutions Group (MSG) produces Wi-Fi and cellular mobility software products. This family of solutions simplifies access to both wired and wireless data networks. In the wireless domain, the company's products support Wi-Fi (802.11 a/b/g) and all major cellular data networking technologies. For wired access, the company's products support traditional analog dial-up, DSL, and Ethernet connectivity. Revenue in this segment is dominated by the company's Roaming Client product. The Roaming Client is a PC or PocketPC-based application developed to allow users to easily locate and connect to Wi-Fi and Wireless Wide Area Networks (WWANs-GPRS, CDMA 1x or other 2.5G cellular networks) data networks. Customers for these products are not typically individual end-users, but cellular carriers, Internet access service providers, manufacturers, distributors, integrators, or other service aggregators. Revenue for the Roaming Client is correlated to the success of data services offered by the customer base. The company describes the roll out of such data services to be in the early stage of market development. It is too early to assess if the market will develop seasonal revenue patterns within the calendar year. Competitors for the Roaming Client range from operating system suppliers such as Apple or Microsoft (which offers a level of WLAN client support through its Windows XP offering) to WLAN NIC (Network Interface Card) suppliers (that bundle minimal clients with their hardware offering) to service aggregators that provide a client as part of their service offering such as iPASS, and Boingo. The company believes it is unique in that many of these competitors are potential customers for the branded client offering. There are few 'client only' competitors in the WLAN space, such as Smith Micro, and Alice Systems (acquired by Birdstep in November 2004). The single biggest competitive condition for the Roaming Client is product performance. Licensing PCTEL has an intellectual property portfolio consisting of over 130 U.S. patents and applications, primarily in analog modem technology. It also has proprietary DSP based embedded modem technology. Independent of the three product lines, the company has an active licensing program designed to monetize its intellectual property. Companies under license at the end of 2004 include 3COM, Intel, Conexant, Broadcom, Silicon Laboratories, Texas Instruments, Smartlink and ESS Technologies. The company has also asserted its 2

patents and is currently litigating against Agere and Lucent, who are unlicensed and the company believes are infringing PCTEL's intellectual property. DEVELOPMENTS The company entered 2001 as an analog modem company, with an intellectual property portfolio that did not have significant revenue associated with it. The personal computer market, which is a significant driver of analog modem volume, was facing significant challenges in the form of reduced IT spending, intense competition and severe pricing pressure. These and other factors caused the company to shift its direction in 2002 from focusing on wire line access for revenue growth to faster growing wireless markets and the monetization of its intellectual property portfolio. The transition out of analog modems was completed in 2003 and the company continues to look for opportunities in wireless markets both through internal development and through acquisitions. The following are the significant events in the transition to wireless and licensing: - Acquisition of cyberPIXIE, Inc. in May 2002, which was the genesis of the company's Mobile Solutions Group. - Exit of the DSP based embedded modem product line in June 2002, and conversion of that technology to a licensing program. - Acquisition of Dynamic Telecommunications, Inc. (DTI) in March 2003. DTI is now known as the RF Solutions Group (RFSG). - Sale of a component of the company's HSP modem product line to Conexant in May of 2003. The company sold the product line but retained its modem patent portfolio for licensing purposes. - Entry into Antenna Products (APG) with acquisition of MAXRAD, Inc. in January 2004. The (APG) line was further augmented by the acquisition of three product lines from Andrew Corporation in October of 2004 and the acquisition of Sigma in July 2005. During the management discussion and analysis, the APG, RFSG, and MSG products are collectively referred to as wireless products, and the HSP modem and embedded modem products as modem products. SALES, MARKETING AND SUPPORT The company sells its products directly to cellular carriers, wireless Internet providers (WISP's), PC OEM's, and wireless equipment manufacturers and indirectly through distributors. PCTEL employs a direct sales force with a thorough level of technical expertise, product background and industry knowledge. The sales force also supports the sales efforts of the company's distributors. The company's marketing strategy is focused on building market awareness and acceptance of the company's new products. The marketing organization also provides a wide range of programs, materials and events to support the sales organization. The company spent approximately $13.1, $11.2 and $7.7 million for the fiscal years 2005, 2004 and 2003 for sales and marketing support. As of December 31, 2005, the company employed 40 individuals in sales and marketing with offices in the U.S., Japan, Israel, Ireland and United Kingdom. 3

Revenue to major customers representing greater than 10% of total revenues during the last three fiscal years are as follows:

YEARS ENDED DECEMBER 31 ------------------ CUSTOMER 2005 2004 2003 - -------- ---- ---- ---- TESSCO Technologies......................................... 11% 10% --% Intel Corporation........................................... --% --% 30% -- -- -- 11% 10% 30% == == ==
The 2005 and 2004 revenue for TESSCO relates to the Antenna Products Group. TESSCO is a distributor of wireless products. The 2003 revenue for Intel relates to a one-time modem licensing settlement. The following table illustrates the percentage of revenues from domestic sales and foreign sales during the last three fiscal years:
YEARS ENDED DECEMBER 31, ------------------ 2005 2004 2003 ---- ---- ---- Domestic sales.............................................. 76% 77% 57% Foreign sales............................................... 24% 23% 43% --- --- --- 100% 100% 100% === === ===
The shift from 2003 to 2004 from foreign to domestic revenue reflects the transition from modems, which are heavily dominated by Asian sales, to wireless products that are heavily dominated by domestic sales. BACKLOG Sales of the company's products are generally made pursuant to standard purchase orders, which are officially acknowledged according to standard terms and conditions. The backlog, while useful for scheduling production or software release dates, is not a meaningful indicator of future revenues as the order to ship cycle is extremely short. RESEARCH AND DEVELOPMENT The company recognizes that a strong technical base is essential to the long-term success and has made a substantial investment in research and development. The company will continue to devote substantial resources to product development and patent submissions. The patent submissions for the three wireless product segments are primarily for defensive purposes, rather than for potential license revenue generation. The company monitors changing customer needs and works closely with the customers, partners and market research organizations to track changes in the marketplace, including emerging industry standards. Research and development expenses include costs for software and hardware development, prototyping, certification and pre-production costs. The company spent approximately $10.0, $8.6 and $7.9 million for the fiscal years 2005, 2004 and 2003, respectively in research and development. MANUFACTURING The company does final assembly of the products for the APG and RFSG products. The company also has arrangements with several contract manufacturers but is not dependent on any one. Should any of these manufacturers be unsatisfactory, other manufacturers are available. The company has no guaranteed supply or long-term contract agreements with any other of its suppliers. MSG products are software licenses and related engineering fees to customize the product for customer networks. The software product delivery cycle is comprised of delivering a product master of the software from which customers make copies for their subscribers. 4

EMPLOYEES As of December 31, 2005, the company had 465 full-time equivalent employees, including 286 in operations, 40 in sales and marketing, 69 in research and development, and 70 in general and administrative functions. The total headcount includes 65 temporary employees in operations. Headcount increased 228 from December 31, 2004, including temporary headcount. The increase is primarily due to the acquisition of Sigma (87) and to transition of the assembly operations for the product lines from Andrew Corporation (115). As of December 31, 2005, 53 of the Sigma employees in Ireland were represented by a labor union. No other employees of the company are represented by a labor union. The company considers employee relations to be good.

ITEM 1A: RISK FACTORS FACTORS THAT MAY AFFECT OUR BUSINESS, FINANCIAL CONDITION AND FUTURE OPERATING RESULTS This annual report on Form 10-K, including this Management's Discussion and Analysis, contains forward-looking statements. These forward-looking statements are subject to substantial risks and uncertainties that could cause our future business, financial condition or results of operations to differ materially from our historical results or currently anticipated results, including those set forth below. Investors should carefully review the information contained in this Section IA. RISKS RELATED TO OUR BUSINESS COMPETITION WITHIN THE WIRELESS CONNECTIVITY PRODUCTS INDUSTRIES IS INTENSE AND IS EXPECTED TO INCREASE SIGNIFICANTLY. OUR FAILURE TO COMPETE SUCCESSFULLY COULD MATERIALLY HARM OUR PROSPECTS AND FINANCIAL RESULTS. The wireless products connectivity markets are intensely competitive. We may not be able to compete successfully against current or potential competitors. We expect competition to increase in the future as current competitors enhance their product offerings, new suppliers enter the wireless connectivity products markets, new communication technologies are introduced and additional networks are deployed. Our client software competes with software developed internally by Network Interface Card (NIC) vendors, service providers for 802.11 networks, and with software developed by large systems integrators. Increased competition could materially and adversely affect our business and operating results through pricing pressures, the loss of market share and other factors. The antenna market is highly fragmented and is served by many local product providers. We may not be able to displace established competitors from their customer base with our products. We may not achieve the design wins necessary to participate in WCDMA network deployments where our products compete. Where we have design wins, we may not be the sole source supplier or may receive only a small portion of the business from each customer. Many of our present and potential competitors have substantially greater financial, marketing, technical and other resources with which to pursue engineering, manufacturing, marketing, and distribution of their products. These competitors may succeed in establishing technology standards or strategic alliances in the connectivity products markets, obtain more rapid market acceptance for their products, or otherwise gain a competitive advantage. We can offer no assurance that we will succeed in developing products or technologies that are more effective than those developed by our competitors. We can offer no assurance that we will be 5

able to compete successfully against existing and new competitors as the connectivity wireless markets evolve and the level of competition increases. OUR ABILITY TO GROW OUR BUSINESS MAY BE THREATENED IF THE DEMAND FOR WIRELESS DATA SERVICES DOES NOT CONTINUE TO GROW. Our ability to compete successfully in the wireless market is dependent on the continued trend toward wireless telecommunications and data communications services. If the rate of growth slows and service providers reduce their capital investments in wireless infrastructure or fail to expand into new geographic markets, our revenue may decline. Wireless data solutions are relatively unproven in the marketplace and some of the wireless technologies have only been commercially introduced in the last few years. We began offering wireless products in the second quarter of fiscal 2002. If wireless data access technology turns out to be unsuitable for widespread commercial deployment, we may not be able to generate enough sales to achieve and grow our business. We have listed below some of the factors that we believe are key to the success or failure of wireless access technology: - reliability and security of wireless access technology and the perception by end-users of its reliability and security, - capacity to handle growing demands for faster transmission of increasing amounts of data, voice and video, - the availability of sufficient frequencies for network service providers to deploy products at commercially reasonable rates, - cost-effectiveness and performance compared to wire line or other high speed access solutions, whose prices and performance continue to improve, - suitability for a sufficient number of geographic regions, and - availability of sufficient site locations for wireless access. The factors listed above influence our customers' purchase decisions when selecting wireless versus other high-speed data access technology. Future legislation, legal decisions and regulation relating to the wireless telecommunications industry may slow or delay the deployment of wireless networks. Wireless access solutions compete with other high-speed access solutions such as digital subscriber lines, cable modem technology, fiber optic cable and other high-speed wire line and satellite technologies. If the market for our wireless solutions fails to develop or develops more slowly than we expect due to this competition, our sales opportunities will be harmed. Many of these alternative technologies can take advantage of existing installed infrastructure and are generally perceived to be reliable and secure. As a result, they have already achieved significantly greater market acceptance and penetration than wireless data access technologies. Moreover, current wireless data access technologies have inherent technical limitations that may inhibit their widespread adoption in many areas. We expect wireless data access technologies to face increasing competitive pressures from both current and future alternative technologies. In light of these factors, many service providers may be reluctant to invest heavily in wireless data access solutions, including Wi-Fi. If service providers do not continue to establish Wi-Fi "hot spots," we may not be able to generate sales for our Wi-Fi products and our revenue may decline. OUR WIRELESS BUSINESS IS DEPENDENT UPON THE CONTINUED GROWTH OF EVOLVING TELECOMMUNICATIONS AND INTERNET INDUSTRIES. Our future success is dependent upon the continued growth of the data communications and wireless industries, particularly with regard to Internet usage. The global data communications and Internet industries are relatively new and evolving rapidly and it is difficult to predict potential growth rates or future trends in technology development for this industry. The deregulation, privatization and economic globalization of the worldwide telecommunications market that have resulted in increased competition and escalating demand for 6

new technologies and services may not continue in a manner favorable to us or our business strategies. In addition, the growth in demand for wireless and Internet services, and the resulting need for high speed or enhanced data communications products and wireless systems, may not continue at its current rate or at all. OUR FUTURE SUCCESS DEPENDS ON OUR ABILITY TO DEVELOP AND SUCCESSFULLY INTRODUCE NEW AND ENHANCED PRODUCTS FOR THE WIRELESS MARKET, WHICH MEET THE NEEDS OF CUSTOMERS. Our revenue depends on our ability to anticipate our existing and prospective customers' needs and develop products that address those needs. Our future success will depend on our ability to introduce new products for the wireless market, anticipate improvements and enhancements in wireless technology and wireless standards, and to develop products that are competitive in the rapidly changing wireless industry. Introduction of new products and product enhancements will require coordination of our efforts with those of our customers, suppliers, and manufacturers to rapidly achieve volume production. If we fail to coordinate these efforts, develop product enhancements or introduce new products that meet the needs of our customers as scheduled, our operating results will be materially and adversely affected and our business and prospects will be harmed. We cannot assure you that product introductions will meet the anticipated release schedules or that our wireless products will be competitive in the market. Furthermore, given the emerging nature of the wireless market, there can be no assurance our products and technology will not be rendered obsolete by alternative or competing technologies. WE MAY EXPERIENCE INTEGRATION OR OTHER PROBLEMS WITH POTENTIAL ACQUISITIONS, WHICH COULD HAVE AN ADVERSE EFFECT ON OUR BUSINESS OR RESULTS OF OPERATIONS. NEW ACQUISITIONS COULD DILUTE THE INTERESTS OF EXISTING STOCKHOLDERS, AND THE ANNOUNCEMENT OF NEW ACQUISITIONS COULD RESULT IN A DECLINE IN THE PRICE OF OUR COMMON STOCK. We may in the future make acquisitions of, or large investments in, businesses that offer products, services, and technologies that we believe would complement our products or services, including wireless products and technology. We may also make acquisitions of, or investments in, businesses that we believe could expand our distribution channels. Even if we were to announce an acquisition, we may not be able to complete it. Additionally, any future acquisition or substantial investment would present numerous risks, including: - difficulty in integrating the technology, operations, internal accounting controls or work force of the acquired business with our existing business, - disruption of our on-going business, - difficulty in realizing the potential financial or strategic benefits of the transaction, - difficulty in maintaining uniform standards, controls, procedures and policies, - dealing with tax, employment, logistics, and other related issues unique to international organizations and assets we acquire, - possible impairment of relationships with employees and customers as a result of integration of new businesses and management personnel, and - impairment of assets related to resulting goodwill, and reductions in our future operating results from amortization of intangible assets. We expect that future acquisitions could provide for consideration to be paid in cash, shares of our common stock, or a combination of cash and our common stock. If consideration for a transaction is paid in common stock, this would further dilute our existing stockholders. 7

WE MAY NEVER ACHIEVE THE ANTICIPATED BENEFITS FROM OUR RECENT ACQUISITION OF SIGMA WIRELESS TECHNOLOGIES. We acquired Sigma Wireless Technologies in July 2005 as part of our continuing efforts to expand our wireless line and product offerings. We may experience difficulties in achieving the anticipated benefits of this acquisition. This acquisition represents an expansion for our Antenna Products Group. Potential risks with this acquisition include: - the loss or decrease in orders of one or more of the major customers, - delay in 3G network deployments utilizing acquired products, - decrease in demand for wireless devices that use the acquired products, - lack of acceptance for electrical tilt antenna products in general - the ability to realize gross and operating margins necessary to achieve targeted results - difficulties in assimilation of related personnel, operations, technologies or products, and - challenges in integrating internal accounting and financial controls for financial reporting purposes. OUR GROSS PROFIT MAY VARY BASED ON THE MIX OF SALES OF OUR PRODUCTS AND LICENSES OF OUR INTELLECTUAL PROPERTY, AND THESE VARIATIONS MAY CAUSE OUR NET INCOME TO DECLINE. We derive a portion of our sales from our software-based connectivity products. Due in part to the competitive pricing pressures that affect our products and in part to increasing component and manufacturing costs, we expect gross profit from both existing and future products to decrease over time. In addition, licensing revenues from our intellectual property historically have provided higher margins than our product sales. Changes in the mix of products sold and the percentage of our sales in any quarter attributable to products as compared to licensing revenues could cause our quarterly results to vary and could result in a decrease in gross profit and net income. ANY DELAYS IN OUR NORMALLY LENGTHY SALES CYCLES COULD RESULT IN CUSTOMERS CANCELING PURCHASES OF OUR PRODUCTS. Sales cycles for our products with major customers are lengthy, often lasting nine months or longer. In addition, it can take an additional nine months or more before a customer commences volume production of equipment that incorporates our products. Sales cycles with our major customers are lengthy for a number of reasons, including: - our original equipment manufacturer customers and carriers usually complete a lengthy technical evaluation of our products, over which we have no control, before placing a purchase order, - the commercial introduction of our products by an original equipment manufacturer and carriers is typically limited during the initial release to evaluate product performance, and - the development and commercial introduction of products incorporating new technologies frequently are delayed. A significant portion of our operating expenses is relatively fixed and is based in large part on our forecasts of volume and timing of orders. The lengthy sales cycles make forecasting the volume and timing of product orders difficult. In addition, the delays inherent in lengthy sales cycles raise additional risks of customer decisions to cancel or change product phases. If customer cancellations or product changes were to occur, this could result in the loss of anticipated sales without sufficient time for us to reduce our operating expenses. 8

OUR REVENUES MAY FLUCTUATE EACH QUARTER DUE TO BOTH DOMESTIC AND INTERNATIONAL SEASONAL TRENDS. The MSG market is in the initial market stages and has yet to display discernable revenue patterns by quarter. The APG and RFSG markets display seasonality in that the first quarter is typically the lowest revenue quarter and each successive quarter is higher. The pattern for APG and RFGS tracks with carrier capital spending plans WE RELY ON INDEPENDENT COMPANIES TO MANUFACTURE, ASSEMBLE AND TEST OUR PRODUCTS. IF THESE COMPANIES DO NOT MEET THEIR COMMITMENTS TO US, OUR ABILITY TO SELL PRODUCTS TO OUR CUSTOMERS WOULD BE IMPAIRED. We have limited manufacturing capability. For some product lines we outsource the manufacturing, assembly, and testing of printed circuit board subsystems. For other product lines, we purchase completed hardware platforms and add our proprietary software. While there is no unique capability with these suppliers, any failure by these suppliers to meet delivery commitments would cause us to delay shipments and potentially be unable to accept new orders for product. In addition, in the event that these suppliers discontinued the manufacture of materials used in our products, we would be forced to incur the time and expense of finding a new supplier or to modify our products in such a way that such materials were not necessary. Either of these alternatives could result in increased manufacturing costs and increased prices of our products. We assemble our APG products in our APG facilities located in Illinois, China, and Ireland. We may experience delays, disruptions, capacity constraints or quality control problems at our assembly facilities, which could result in lower yields or delays of product shipments to our customers. In addition, we are having an increasing number of our APG products manufactured in China via contract manufacturers. Any disruption of our own or contract manufacturers' operations could cause us to delay product shipments, which would negatively impact our sales, competitive reputation and position. In addition, if we do not accurately forecast demand for our products, we will have excess or insufficient parts to build our product, either of which could seriously affect our operating results. IN ORDER FOR US TO OPERATE AT A PROFITABLE LEVEL AND CONTINUE TO INTRODUCE AND DEVELOP NEW PRODUCTS FOR EMERGING MARKETS, WE MUST ATTRACT AND RETAIN OUR EXECUTIVE OFFICERS AND QUALIFIED TECHNICAL, SALES, SUPPORT AND OTHER ADMINISTRATIVE PERSONNEL. Our performance is substantially dependent on the performance of our current executive officers and certain key engineering, sales, marketing, financial, technical and customer support personnel. If we lose the services of our executives or key employees, replacements could be difficult to recruit and, as a result, we may not be able to grow our business. Competition for personnel, especially qualified engineering personnel, is intense. We are particularly dependent on our ability to identify, attract, motivate and retain qualified engineers with the requisite education, background and industry experience. As of December 31, 2005, we employed a total of 69 people in our engineering department. If we lose the services of one or more of our key engineering personnel, our ability to continue to develop products and technologies responsive to our markets may be impaired. FAILURE TO MANAGE OUR TECHNOLOGICAL AND PRODUCT GROWTH COULD STRAIN OUR MANAGEMENT, FINANCIAL AND ADMINISTRATIVE RESOURCES. Our ability to successfully sell our products and implement our business plan in rapidly evolving markets requires an effective management planning process. Future product expansion efforts could be expensive and put a strain on our management by significantly increasing the scope of their responsibilities and by increasing the demands on their management abilities. To effectively manage our growth in these new technologies, we must enhance our marketing, sales, research and development areas. 9

WE MAY BE SUBJECT TO LITIGATION REGARDING INTELLECTUAL PROPERTY ASSOCIATED WITH OUR WIRELESS BUSINESS AND THIS COULD BE COSTLY TO DEFEND AND COULD PREVENT US FROM USING OR SELLING THE CHALLENGED TECHNOLOGY. In recent years, there has been significant litigation in the United States involving intellectual property rights. We have from time to time in the past-received correspondence from third parties alleging that we infringe the third party's intellectual property rights. We expect potential claims to increase in the future, including with respect to our wireless business. Intellectual property claims against us, and any resulting lawsuit, may result in our incurring significant expenses and could subject us to significant liability for damages and invalidate what we currently believe are our proprietary rights. These lawsuits, regardless of their merits or success, would likely be time-consuming and expensive to resolve and could divert management's time and attention. This could have a material and adverse effect on our business, results of operation, financial condition and prospects. Any potential intellectual property litigation against us related to our wireless business could also force us to do one or more of the following: - cease selling, incorporating or using technology, products or services that incorporate the infringed intellectual property, - obtain from the holder of the infringed intellectual property a license to sell or use the relevant technology, which license may not be available on acceptable terms, if at all, or - redesign those products or services that incorporate the disputed intellectual property, which could result in substantial unanticipated development expenses. If we are subject to a successful claim of infringement related to our wireless intellectual property and we fail to develop non-infringing intellectual property or license the infringed intellectual property on acceptable terms and on a timely basis, operating results could decline and our ability to grow and sustain our wireless business could be materially and adversely affected. As a result, our business, financial condition, results of operation and prospects could be impaired. We may in the future initiate claims or litigation against third parties for infringement of our intellectual property rights or to determine the scope and validity of our proprietary rights or the proprietary rights of our competitors. These claims could also result in significant expense and the diversion of technical and management personnel's attention. UNDETECTED SOFTWARE ERRORS OR FAILURES FOUND IN NEW PRODUCTS MAY RESULT IN A LOSS OF CUSTOMERS OR A DELAY IN MARKET ACCEPTANCE OF OUR PRODUCTS. Our products may contain undetected software errors or failures when first introduced or as new versions are released. To date, we have not been made aware of any significant software errors or failures in our products. However, despite testing by us and by current and potential customers, errors may be found in new products after commencement of commercial shipments, resulting in loss of customers or delay in market acceptance. OUR FINANCIAL POSITION AND RESULTS OF OPERATIONS MAY BE ADVERSELY AFFECTED IF TAX AUTHORITIES CHALLENGE US AND THE TAX CHALLENGES RESULT IN UNFAVORABLE OUTCOMES. We currently have international subsidiaries located in Japan, China, Ireland, United Kingdom, and Israel as well as international branch offices located in Hong Kong and Taiwan. The complexities resulting from operating in several different tax jurisdictions increase our exposure to worldwide tax challenges. CONDUCTING BUSINESS IN INTERNATIONAL MARKETS INVOLVES FOREIGN EXCHANGE RATE EXPOSURE THAT MAY LEAD TO REDUCED PROFITABILITY. With the recent acquisition of Sigma, we have increased risk from foreign currency exposure. Sigma's functional currency is the Euro, and Sigma conducts business in both the Euro and pounds sterling. We believe that foreign exchange exposures may lead to reduced profitability. 10

RISKS RELATED TO OUR INDUSTRY OUR INDUSTRY IS CHARACTERIZED BY RAPIDLY CHANGING TECHNOLOGIES. IF WE ARE NOT SUCCESSFUL IN RESPONSE TO RAPIDLY CHANGING TECHNOLOGIES, OUR PRODUCTS MAY BECOME OBSOLETE AND WE MAY NOT BE ABLE TO COMPETE EFFECTIVELY. The wireless data access business is characterized by rapidly changing technologies, short product life cycles and frequent new product introductions. To remain competitive, we have successfully introduced several new products. Both the cellular (2.5G and 3G) and Wi-Fi (802.11) spaces are rapidly changing and prone to standardization. We will continue to evaluate, develop and introduce technologically advanced products that will position us for possible growth in the wireless data access market. If we are not successful in response to rapidly changing technologies, our products may became obsolete and we may not be able to compete effectively. CHANGES IN LAWS OR REGULATIONS, IN PARTICULAR, FUTURE FCC REGULATIONS AFFECTING THE BROADBAND MARKET, INTERNET SERVICE PROVIDERS, OR THE COMMUNICATIONS INDUSTRY, COULD NEGATIVELY AFFECT OUR ABILITY TO DEVELOP NEW TECHNOLOGIES OR SELL NEW PRODUCTS AND THEREFORE, REDUCE OUR PROFITABILITY. The jurisdiction of the Federal Communications Commission, or FCC, extends to the entire communications industry, including our customers and their products and services that incorporate our products. Future FCC regulations affecting the broadband access services industry, our customers or our products may harm our business. For example, future FCC regulatory policies that affect the availability of data and Internet services may impede our customers' penetration into their markets or affect the prices that they are able to charge. In addition, FCC regulatory policies that affect the specifications of wireless data devices may impede certain of our customers' ability to manufacture their products profitably, which could, in turn, reduce demand for our products. Furthermore, international regulatory bodies are beginning to adopt standards for the communications industry. Although our business has not been hurt by any regulations to date, in the future, delays caused by our compliance with regulatory requirements may result in order cancellations or postponements of product purchases by our customers, which would reduce our profitability. RISKS RELATED TO OUR LICENSING PROGRAM OUR ABILITY TO SUSTAIN OR GROW OUR REVENUE FROM THE LICENSING OF OUR INTELLECTUAL PROPERTY IS SUBJECT TO MANY RISKS, AND ANY INABILITY TO SUCCESSFULLY LICENSE OUR INTELLECTUAL PROPERTY COULD MATERIALLY AND ADVERSELY AFFECT OUR BUSINESS, FINANCIAL CONDITION AND OPERATING RESULTS. We may not be able to sustain our revenue from the licensing of our intellectual property. In addition to our wireless product lines, we offer our intellectual property through licensing and product royalty arrangements. We have over 130 U.S. patents granted or pending addressing both essential International Telecommunications Union and non-essential technologies. In connection with our intellectual property licensing efforts, we have filed several patent infringement lawsuits and are aggressively pursuing unlicensed companies to license their unauthorized use of our intellectual property. We have pending patent infringement litigation claims with Agere and Lucent. We expect litigation to continue to be necessary to enforce our intellectual property rights and to determine the validity and scope of the proprietary rights of others. Because of the high degree of complexity of the intellectual property at issue, the inherent uncertainties of litigation in general and the preliminary nature of these litigation matters, we cannot assure you that we will ultimately prevail or receive the judgments that we seek. We may not be able to obtain licensing agreements from these companies on terms favorable to us, if at all. In addition, we may be required to pay substantial monetary damages as a result of claims these companies have brought against us which could materially and adversely affect our business, financial condition and operating results. 11

LITIGATION EFFORTS RELATED TO OUR LICENSING PROGRAM ARE EXPECTED TO BE COSTLY AND MAY NOT ACHIEVE OUR OBJECTIVES. Litigation such as our suits with Agere and Lucent can take years to resolve and can be expensive to pursue or defend. We currently expect our intellectual property litigation costs to be within a range of $2.5 to $3.0 million in 2006, in the absence of any settlement. In addition, the allegations and claims involved in these lawsuits, even if ultimately resolved in our favor, could be time consuming to litigate and divert management attention. We may not ultimately prevail in these matters or receive the judgments that we seek. We could also face substantial monetary damages as a result of claims others bring against us. In addition, court decisions on current pending and future motions could have the effect of determining the ultimate outcome of the litigation prior to a trial on the merits, or strengthen or weaken our ability to assert claims and defenses in the future. Accordingly, an adverse judgment could seriously harm our business, financial position and operating results and cause our stock price to decline substantially. WE EXPECT TO CONTINUE TO BE SUBJECT TO LITIGATION REGARDING INTELLECTUAL PROPERTY CLAIMS RELATED TO OUR LICENSING PROGRAM WHICH COULD IMPAIR OUR ABILITY TO GROW OR SUSTAIN REVENUES FROM OUR LICENSING EFFORTS. As we continue to aggressively pursue licensing arrangements with companies that are using our intellectual property without our authorization, we expect to continue to be subject to lawsuits that challenge the validity of our intellectual property or that allege that we have infringed third party intellectual property rights. Any of these claims could results in substantial damages against us and could impair our ability to grow and sustain our licensing business. This could materially and adversely affect our business, financial condition, operating results and prospects. As a result, at least in part, of our licensing efforts to date, we are currently subject to claims from Agere and Lucent regarding patent infringement matters of the nature described above. We have also been subject to claims from others in the past regarding similar matters. In addition, in recent years, there has been significant litigation in the United States involving intellectual property rights. We expect these claims to increase as our intellectual property portfolio becomes larger. Intellectual property claims against us, and any resulting lawsuit, may result in our incurring significant expenses and could subject us to significant liability for damages and invalidate what we currently believe are our proprietary rights. These lawsuits, regardless of their merits or success, would likely be time-consuming and expensive to resolve and could divert management's time and attention. OUR ABILITY TO ENFORCE OUR INTELLECTUAL PROPERTY RIGHTS MAY BE LIMITED, AND ANY LIMITATION COULD ADVERSELY AFFECT OUR ABILITY TO SUSTAIN OR INCREASE REVENUE FROM OUR LICENSING PROGRAM. Our ability to sustain and grow revenue from the licensing of our intellectual property is dependent on our ability to enforce our intellectual property rights. Our ability to enforce these rights is subject to many challenges and may be limited. For example, one or more of our pending patents may never be issued. In addition, our patents, both issued and pending, may not prove enforceable in actions against alleged infringers. Agere and Lucent have currently pending claims seeking to invalidate one or more of our patents. If a court were to invalidate one or more of our patents, this could materially and adversely affect our licensing program. Furthermore, some foreign laws, including those of various countries in Asia, do not protect our proprietary rights to the same extent as United States laws. RISKS RELATED TO OUR COMMON STOCK THE TRADING PRICE OF OUR STOCK PRICE MAY BE VOLATILE BASED ON A NUMBER OF FACTORS, SOME OF WHICH ARE NOT IN OUR CONTROL. The trading price of our common stock has been highly volatile. The common stock price has fluctuated from a low of $6.70 to a high of $10.16 during 2005. Our stock price could be subject to wide fluctuations in response to a variety of factors, many of which are out of our control, including: - announcements of technological innovations, - new products or services offered by us or our competitors, 12

- actual or anticipated variations in quarterly operating results, - outcome of ongoing intellectual property related litigations, - changes in financial estimates by securities analysts, - conditions or trends in our industry, - our announcement of significant acquisitions, strategic partnerships, joint ventures or capital commitments, - additions or departures of key personnel, - mergers and acquisitions, and - sales of common stock by our stockholders or us. In addition, the NASDAQ National Market, where many publicly held telecommunications companies, including PCTEL, are traded, often experiences extreme price and volume fluctuations. These fluctuations often have been unrelated or disproportionate to the operating performance of these companies. In the past, following periods of volatility in the market price of an individual company's securities, securities class action litigation often has been instituted against that company. This type of litigation, if instituted, could result in substantial costs and a diversion of management's attention and resources. PROVISIONS IN OUR CHARTER DOCUMENTS MAY INHIBIT A CHANGE OF CONTROL OR A CHANGE OF MANAGEMENT, WHICH MAY CAUSE THE MARKET PRICE FOR OUR COMMON STOCK TO FALL AND MAY INHIBIT A TAKEOVER OR CHANGE IN OUR CONTROL THAT A STOCKHOLDER MAY CONSIDER FAVORABLE. Provisions in our charter documents could discourage potential acquisition proposals and could delay or prevent a change in control transaction that our stockholders may favor. These provisions could have the effect of discouraging others from making tender offers for our shares, and as a result, these provisions may prevent the market price of our common stock from reflecting the effects of actual or rumored takeover attempts and may prevent stockholders from reselling their shares at or above the price at which they purchased their shares. These provisions may also prevent changes in our management that our stockholders may favor. Our charter documents do not permit stockholders to act by written consent, do not permit stockholders to call a stockholders meeting, and provide for a classified board of directors, which means stockholders can only elect, or remove, a limited number of our directors in any given year. Our board of directors has the authority to issue up to 5,000,000 shares of preferred stock in one or more series. The board of directors can fix the price, rights, preferences, privileges and restrictions of this preferred stock without any further vote or action by our stockholders. The rights of the holders of our common stock will be affected by, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. Further, the issuance of shares of preferred stock may delay or prevent a change in control transaction without further action by our stockholders. As a result, the market price of our common stock may drop. UNDER REGULATIONS REQUIRED BY THE SARBANES-OXLEY ACT OF 2002, IF WE ARE UNABLE TO SUCCESSFULLY IMPLEMENT PROCESSES AND PROCEDURES TO ACHIEVE AND MAINTAIN EFFECTIVE INTERNAL CONTROL OVER OUR FINANCIAL REPORTING, OUR ABILITY TO PROVIDE RELIABLE AND TIMELY FINANCIAL REPORTS COULD BE HARMED. We must comply with the rules promulgated under section 404 of the Sarbanes-Oxley Act of 2002. Section 404 requires an annual management report assessing the effectiveness of our internal control over financial reporting, a report by our independent registered public accounting firm addressing this assessment, and a report by our independent registered public accounting firm addressing the effectiveness of our internal control. As disclosed in the Company's 2004 Annual Report on Form 10-K and in its Quarterly Reports on Form 10-Q for each of the first three quarters of 2005, the Company previously reported a material weakness in internal control over the accounting for income taxes, including the determination of income taxes payable, 13

deferred income tax assets and liabilities and the related income tax provision. Specifically, the Company did not have effective controls over determining net operating loss carry backs, applicable state tax rates applied, and the tax effect of stock option exercises. In addition, the Company did not have effective controls to monitor the difference between the income tax basis and the financial reporting basis of assets and liabilities and reconcile the difference to deferred income tax assets and liabilities. The Company has made significant progress in its efforts to remediate this material weakness during 2005. This is further supported by the Company's overall positive results from its 2005 internal control compliance testing required by Section 404 of the Sarbanes-Oxley Act of 2002, which was carried out by the Company in the third and fourth quarters of 2005. However, the company has not demonstrated operating effectiveness with respect to controls over the completeness and accuracy of its income tax provision and the presentation and disclosures related to income taxes in 2005. This control deficiency could result in a misstatement of the income tax provision and income tax related financial statement disclosures that would result in a material misstatement of the annual or interim financial statements that would not be prevented or detected. Accordingly, management has concluded that this control deficiency constitutes a material weakness as of December 31, 2005 as discussed in "Management's Report on Internal Control Over Financial Reporting" in item 9A. In order to remediate this deficiency in internal controls, the Company will continue its training and education efforts in this area so that operating effectiveness can be demonstrated over a period of time that is sufficient to support the conclusion that the material weakness has been remediated. In addition, to further enhance the controls surrounding the accounting for income taxes, the Company will continue its efforts with respect to 1) its oversight over the quarterly and annual preparation of its tax provision and related disclosures by its outside tax consultant, and 2) the need to consider additional resources to help execute its internal controls over the accounting for income taxes. Nevertheless, we cannot be certain in future periods that other control deficiencies that may constitute one or more "significant deficiencies" (as defined by the relevant auditing standards) or material weaknesses in our internal control over financial reporting, will not be identified. The occurrence of control deficiencies in our internal control, and material weaknesses in particular, adversely affect our ability to report our financial results on a timely and accurate basis. While we are expending significant resources in developing the necessary documentation and testing procedures required by Section 404, we cannot be certain that the actions we are taking to improve, achieve and maintain our internal control over financial reporting will be adequate or that we will be able to implement our planned processes and procedures. If we do not complete our compliance activities under Section 404 in a timely manner, or the processes and procedures that we implement for our internal control over financial reporting are inadequate, our ability to provide reliable and timely financial reports, and consequently our business and operating results, could be harmed. This in turn could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial reports, which could cause the market price of our Common Stock to decline. ITEM 1B: UNRESOLVED STAFF COMMENTS None ITEM 2: PROPERTIES The company's corporate headquarters are in the Chicago, Illinois facility. All properties are in good condition and are suitable for the purposes for which they are used. 14

The following tables lists the company's significant facilities:

SQUARE FEET OWNED/LEASED LEASE TERM SEGMENT ----------- ------------ ---------- ------- Bloomingdale, Illinois................... 75,517 Owned N/A APG Dublin, Ireland.......................... 32,922 Leased 2010 APG Germantown, Maryland (Observation Drive)................................. 20,704 Leased 2013 RFS Chicago, Illinois........................ 12,624 Leased 2007 MSG Germantown, Maryland (Wisteria Drive).... 9,135 Leased 2007 RFS
In October 2005, the company signed a new five-year lease in Germantown, Maryland (Observation Drive) for the RFSG segment. RFSG relocated office and assembly operations to this facility in February 2006. With the purchase of Sigma in July 2005, the company signed a lease for manufacturing and office space in Dublin, Ireland through April 2010, with an early termination provision in July 2007 and July 2008. The January 2004 acquisition of MAXRAD included a building with 31,150 square feet located in Hanover Park, Illinois. On June 29, 2005, the company sold the Hanover Park, Illinois building to Haase Chandler, LLC. in exchange for a cash payment of approximately $2.3 million. After selling expenses, the company recorded a loss on sale of the building and related furniture and fixtures of approximately $138,000. In November 2004, the company purchased a building with approximately 75,000 square feet located in Bloomingdale, Illinois to accommodate the MAXRAD products and the products lines acquired from Andrew Corporation. In June 2005, the building in Bloomingdale, Illinois was completed, and APG relocated its operations to the new building. The company also has leased sales offices in Japan, United Kingdom, and Israel. APG has an assembly facility in Tianjin, China. The company believes that it has adequate space for its current needs. ITEM 3: LEGAL PROCEEDINGS The company has from time to time in the past received correspondence from third parties, and may receive communications from additional third parties in the future, asserting that the products infringe on their intellectual property rights, that the patents are unenforceable or that the company has inappropriately licensed the intellectual property to third parties. The company expects these claims to increase as our intellectual property portfolio becomes larger. These claims could affect the company's relationships with existing customers and may prevent potential future customers from purchasing the company's products or licensing the technology. Intellectual property claims against the company, and any resulting lawsuit, may result in incurring significant expenses and could subject the company to significant liability for damages and invalidate the company's proprietary rights. These lawsuits, regardless of their success, would likely be time-consuming and expensive to resolve and could divert management's time and attention. In addition, any claims of this kind, whether they are with or without merit, could cause product shipment delays or require the company to enter into royalty or licensing agreements. In the event that PCTEL does not prevail in litigation, the company could be prevented from selling the company's products or be required to enter into royalty or licensing agreements on terms, which may not be acceptable to the company. PCTEL could also be prevented from selling the company's products or be required to pay substantial monetary damages. Should PCTEL cross license the intellectual property in order to obtain licenses, the company may no longer be able to offer a unique product. To date, PCTEL has not obtained any licenses from 3Com and the other companies from whom the company has received communication. Ronald H. Fraser v. PC-Tel, Inc., Wells Fargo Shareowner Services, Wells Fargo Bank Minnesota, N.A. In March 2002, plaintiff Ronald H. Fraser ("Fraser") filed a complaint in the California Superior Court for breach of contract and declaratory relief against the company, and for breach of contract, conversion, 15

negligence and declaratory relief against the company's transfer agent, Wells Fargo Bank Minnesota, N.A. The complaint seeks compensatory damages allegedly suffered by Fraser as a result of the sale of certain stock by Fraser during a secondary offering in April, 2000. At a mandatory settlement conference held in September, 2004, Fraser stipulated to judgment in favor of the company. In November, 2004 Fraser appealed the judgment entered against him. Fraser filed his opening brief in October 2005. The appellant's reply brief is due in March 2006. While the company believes that this appeal is without merit and intends to defend the appeal vigorously, the company cannot predict or determine the outcome or resolution of this proceeding or the potential range of loss if any. Litigation with U.S. Robotics In May 2003, the company filed in the U.S. District Court for the Northern District of California a patent infringement lawsuit against U.S. Robotics Corporation claiming that U.S. Robotics has infringed one of the company's patents. U.S. Robotics counterclaimed asking for a declaratory judgment that the claims of the patent are invalid and not infringed. In December 2005, the parties entered into a settlement agreement which was favorable to the company, and the Court granted the parties' stipulated request that all claims and counterclaims in the action be dismissed with prejudice. Under the agreement, U.S. Robotics will take a license to specific PCTEL modem patents. PCTEL receives a lump-sum royalty payment, a cross-license to U.S. Robotics patents and patent applications, and royalties in the future that can be satisfied with cash payments or product purchases. Litigation with Agere and Lucent In May 2003, the company filed in the U.S. District Court for the Northern District of California a patent infringement lawsuit against Agere Systems and Lucent Technologies claiming that Agere has infringed four of the company's patents and that Lucent has infringed three of the company's patents. Agere counterclaimed asking for a declaratory judgment that the claims of the four patents are invalid, unenforceable and not infringed by Agere. Because of a then-pending reexamination proceeding for PCTEL's U.S. Patent No. 5,787,305 (the '305 patent), the claims against Agere and Lucent relating to the '305 patent were stayed by stipulation of the parties. Claims construction discovery under the Patent Local Rules was taken with respect to the three patents as to which the litigation was not stayed, and the claims construction issues relating to those patents have been briefed to the Court. A hearing on the construction of the claims of those patents was held in May 2005, and the court issued its claim construction ruling in September 2005. The stay regarding the '305 patent was lifted by stipulation of the parties after the company received the Reexamination Certified from the U.S. Patent Office. Claims construction discovery was taken with respect to the '305 patent. A hearing on the construction of the claims of the '305 patent was held in January 2006 and the court has taken the matter under submission. No trial date has been set. Although the company believes that it has meritorious claims and defenses, the company cannot predict or determine the outcome or resolution of this proceeding or the potential range of loss if any. 16

ITEM 7: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements include, among other things, statements concerning the future operations, financial condition and prospects, and business strategies. The words "believe," "expect," "anticipate" and other similar expressions generally identify forward-looking statements. Investors in the common stock are cautioned not to place undue reliance on these forward-looking statements. These forward-looking statements are subject to substantial risks and uncertainties that could cause the future business, financial condition, or results of operations to differ materially from the historical results or currently anticipated results. Investors should carefully review the information contained under the caption "Factors That May Affect the Business, Financial Condition, and Future Operating Results," beginning on page 24 and elsewhere in, or incorporated by reference into, this report. INTRODUCTION PCTEL is focused on growing wireless revenue and maximizing the monetary value of its intellectual property. These are the two key priorities for the company in 2006. The company reports revenue and gross profit for APG, RFSG, MSG, Licensing and Modems as separate product segments. Growth in wireless product revenue is dependent both on gaining further revenue traction in the existing product profile as well as further acquisitions to support the wireless initiatives. Revenue growth in the APG segment is tied to emerging wireless applications in broadband wireless, in-building wireless, wireless Internet service providers, GPS and Mobile SATCOM. The LMR, PMR, DPMR and on-glass mobile antenna applications represent mature markets. A critical factor for revenue growth is the successful absorption of Sigma Wireless Technologies Limited ("Sigma") acquired in July 2005. Revenue in the RFSG segment is tied to the deployment of new wireless technology, such as 2.5G and 3G, and the need for existing wireless networks to be tuned and reconfigured on a regular basis. Revenue growth in the MSG segment is correlated to the success of data services offered by the customer base. The roll out of such data services is in the early stage of market development. Licensing revenue is dependent on the signing of new license agreements and the success of the licensees in the marketplace. New licenses often contain up front payments pertaining to past royalty liability, or one time payments if the license is perpetual. This can make licensing revenue uneven. The company has found it necessary to enter into litigation from time to time as a means to bring companies under license. The company is currently in litigation with Agere and Lucent over the use of PCTEL's intellectual property. This litigation is the single largest opportunity to maximize the monetary value of the company's intellectual property. Our largest revenue segment, APG, was gross profit margin challenged in 2005, primarily due to the operating parameters of the Sigma product lines. A critical factor for gross profit enhancement as well as operating cost efficiency for the company going forward is the successful integration of Sigma. The Company is evaluating gross profit and operating expense alternatives with respect to the Dublin facility and its integration. 20

CRITICAL ACCOUNTING POLICIES The preparation of the company's consolidated financial statements in accordance with generally accepted accounting principles requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the period reported. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty. Management bases its estimates and judgments on historical experience, market trends, and other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. Management believes the following critical accounting policies reflect the more significant judgments and estimates used in the preparation of its consolidated financial statements. Management has discussed the critical accounting policies with the Audit Committee. REVENUE RECOGNITION The company sells antenna products and software defined radio products, and licenses the modem technology through the licensing program. The company records the sale of these products, including related maintenance, and the licensing of the intellectual property as revenue. In accordance with SAB No. 104, the company recognizes revenue when the following criteria are met: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, price is fixed and determinable, and collectibility is reasonably assured. The company recognizes revenue for sales of the antenna products and software defined radio products, when title transfers, which is generally upon shipment from the factory. PCTEL sells these products into both commercial and secure application government markets. Title for sales into the commercial markets generally transfers upon shipment from the factory. Products that are sold into the secure application government market are generally designed to a unique specification. Title for sales into the government markets generally does not transfer until acceptance for the first units and then upon shipment thereafter. Revenue is recognized for antenna products sold to major distributors upon shipment from the factory. The company allows its major antenna product distributors to return product under specified terms and conditions. The company accrues for product returns in accordance with FAS 48, "Revenue Recognition When Right of Return Exists". The company recognizes revenue from the Wi-Fi and cellular mobility software, including related maintenance rights, under SOP 97-2 Software Revenue Recognition. If the software license is perpetual and vendor specific objective evidence can be established for the software license and any related maintenance rights, the software license revenue is recognized upon delivery of the software and the maintenance is recorded pro-rata over the life of the maintenance rights. If part of the licensing agreement requires engineering services to customize software for the customer needs, the revenue for these services is recognized when the initial software license is delivered. If vendor specific objective evidence cannot be established, and the only undelivered item is maintenance, the software license revenue, the revenue associated with engineering services, if applicable, and the related maintenance rights are combined and recognized pro-rata over the expected term of the maintenance rights. If vendor specific evidence cannot be established on any of the non-maintenance elements, the revenue is recorded pro-rata over the life of the contractual obligation. The company records intellectual property licensing revenue when; it has a licensing agreement, the amount of related royalties is known for the accounting period reported, and collectibility is reasonably assured. Knowledge of the royalty amount specific to an accounting period is either in the form of a royalty report specific to a quarter, a contractual fixed payment in the license agreement specific to a quarter, or the pro-rata amortization of a fixed payment related to multiple quarters over those quarters using the operating lease method. If a license agreement provides for a fixed payment related to periods prior to the license effective date (the past) and volume-based royalties going forward, the fixed payment is recognized at the license effective date and the volume based royalties are recognized as royalty reports are received. If the license provides for a fixed payment for the past and for a finite future period, to be followed by volume based royalties thereafter, the fixed payment is recorded under the operating lease method and recognized pro-rata from the effective date through the end of the period covered by the fixed payment. If a one-time license 21

payment is made for a perpetual license, with no future obligations on behalf of the company, revenue is recognized under the capitalized lease method upon the effective date. There is one exception to the recognition of intellectual property licensing as revenue. The company signed a licensing agreement with Conexant Systems, Inc. ("Conexant") simultaneously with the sale of its HSP modem product line to Conexant in 2003. Because the HSP modem product line also requires a license to the company's patent portfolio, the gain on sale of the product line and the licensing stream are not separable for accounting purposes. Ongoing royalties from Conexant are presented in the income statement as Gain on Sale of Assets and Related Royalties. INVENTORY Inventories are stated at the lower of cost or market and include material, labor and overhead costs. Inventories as of December 31, 2005 and 2004 were composed of raw materials, subassemblies, work-in-process, and finished goods. The company regularly monitors inventory quantities on hand. Reserves for excess inventory are calculated based on the company's estimate of inventory in excess of normal and planned usage. Obsolete reserves are based on the company's identification of inventory having no realizable value. These reserves are based on the company's estimates and judgments regarding the utilization of the inventory. Due to competitive pressures and technological innovation, the company may have excess inventory in the future. Write-downs of inventories would have a negative impact on gross profit. STOCK-BASED COMPENSATION The company will adopt SFAS 123R in the quarter ending March 31, 2006 on a prospective basis; however, until then, and as currently permitted by SFAS 123 "Accounting for Stock-Based Compensation", and SFAS 148 "Accounting for Stock-Based Compensation -- Transition and Disclosure", we continue to apply the accounting provisions of Accounting Principles Board Opinion Number 25, "Accounting for Stock Issued to Employees" (APB 25), and related interpretations, with regard to the measurement of compensation cost for options granted under our stock option plans. The company accounts for the stock option plans whereby compensation cost for stock options is measured as the excess, if any, of the fair market value of a share of the stock at the date of the grant over the amount that must be paid to acquire the Stock. SFAS No. 123 defines a fair value based method of accounting for employee stock options, but allows companies to continue to measure compensation cost for employees using the intrinsic value method of APB No. 25. The company does not expense stock options, but does expense restricted stock grants. The company records the issuance of restricted stock grants based on the fair value on the date of the grant and amortizes the value over the life of the restriction using the straight-line method. As required by SFAS No. 123, the summary pro forma effects to reported income as if the company had elected to recognize compensation expense based on the fair value of the stock based awards to the company's employees is disclosed. The calculation of the fair value of these awards is determined using the Black-Scholes option-pricing model. The highly subjective assumptions underlying this model include expected stock price volatility and expected option life. In advance of adopting SFAS 123R, the company modified the measurement period for calculating volatility. The company believes five years more accurately measures the expected life or term of the option. In 2006, the company will also incorporate a forfeiture rate based on historical experience. In 2005 and prior, the company recognized forfeitures as incurred. All other assumptions will be consistent with the 2005 option pricing model. See footnote 1 related to stock compensation expense. GOODWILL AND IMPAIRMENT OF LONG LIVED ASSETS Effective January 1, 2002, the company adopted the provisions of SFAS No. 142, "Goodwill and Other Intangibles," under which goodwill is no longer amortized. Through a third-party valuation firm the company assessed the need to record impairment losses on goodwill when indicators of impairment are present such as a significant industry downturn, significant decline in the market value of the company, or significant reductions in projected future cash flows. At least annually, typically in the fourth quarter, the company reviews the value of goodwill by reporting unit.a. During this review, the significant assumptions used in determining the original cost of long-lived assets are reevaluated. The company determines whether there has been a permanent 22

impairment of the value of goodwill by comparing future estimated undiscounted cash flows by reporting unit to the asset's carrying value. If the carrying value of the asset exceeds the estimated future undiscounted cash flows, a loss is recorded as the excess of the asset's carrying value over fair value. The company conducted the annual impairment test of goodwill as of October 31, 2005. A third-party valuation firm was engaged to assist in the evaluation. The estimate of future undiscounted cash flows for this test was based on historical sales trends, financial projections, market analysis, capital expenditure needs, working capital needs, analyst reports, and other data pertinent to the valuation as provided by the company and obtained from public, financial, and industry sources. The company's assumptions required significant judgment and actual cash flows may differ from those forecasted. The company believes the assumptions used for discounting future cash flows were reasonable. Based on the results of the test, there was no impairment of goodwill. INCOME TAXES The company provides for income taxes under the provisions of SFAS No. 109, "Accounting for Income Taxes." SFAS No. 109 requires an asset and liability based approach in accounting for income taxes. Deferred income tax assets and liabilities are recorded based on the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates. Valuation allowances are provided against tax assets, which are not likely to be realized. The company has international subsidiaries located in Japan, China, Ireland, United Kingdom and Israel as well as an international branch office located in Hong Kong. The complexities brought on by operating in several different tax jurisdictions inevitably lead to an increased exposure to worldwide taxes. Should review of the tax filings result in unfavorable adjustments to the company's tax returns, the operating results, cash flows, and financial position could be materially and adversely affected. The company believes there will not be any significant adjustments related to foreign taxes. As part of the process of preparing the consolidated financial statements, the company is required to estimate the income taxes, which involves estimating the actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities. Significant management judgment is required to assess the likelihood that the deferred tax assets will be recovered from future taxable income. The company maintains a full valuation allowance against the deferred tax assets. In the event it was determined that the company could realize the deferred tax assets in the future in excess of the net recorded amount, an adjustment to the deferred tax asset would increase income in the period such determination was made. DEFINED BENEFIT RETIREMENT PLANS Approximately 56 current and former employees of Sigma participate in a defined benefit plan. Prior to the acquisition in July 2005 and through December 2005, these employees participated in the Sigma Communications Group Retirement and Death Benefit Plan ("old plan"). Effective December 2003, this plan was frozen to new employees. In January 2006, the Sigma participants from the old plan were transferred to a new retirement and death benefit plan ("PCTEL Europe Pension Plan" or "new plan"). The PCTEL Europe Pension Plan has identical attributes as the old plan. The company accounts for its defined benefit pension plans in accordance with SFAS No. 87, "Employers' Accounting for Pensions," which requires that amounts recognized in financial statements be determined on an actuarial basis. The measurement of the company's pension obligations, costs and liabilities is dependent on a variety of assumptions selected by the company and used by the company's actuaries. These assumptions include estimates of the present value of projected future pension payments to plan participants, taking into consideration the likelihood of potential future events such as salary increases and demographic experience. The assumptions used in developing the required estimates include the following key factors: discount rates, salary growth, retirement rates, inflation, expected return on plan assets and mortality rates. The discount rate is the rate of interest used to discount benefit obligations and has been determined by reference to market yields at the balance sheet date on high quality corporate bonds. The currency and term of 23

the corporate bonds is consistent with the currency and estimated term of the post-employment benefit obligations. At the measurement date of December 31, 2005 the iBoxx index of euro-denominated AA-rated corporate bonds yielded 4.01% per annum, with individual stocks yielding higher amounts. Taking into account the profile and duration of the plan's liabilities, a discount rate of 4.25% has been adopted. The investment strategy pursued by the Pension Consensus Fund is to broadly maintain a diversified portfolio of 60%-90% in real assets such as equities and property, with the balance in monetary assets such as fixed interest and cash. The expected return on plan assets of 6.5% was based on the current asset allocation and the long-term expected returns for each asset class. For the six months ended December 31, 2005, the company recognized consolidated pension expense of $129,000 and contributed approximately $62,000 to the new plan. The company's funding policy is to contribute cash to the pension plans in order to at least meet the minimum contribution requirements. The company will be required to make payments for the under funded amount over a six and one half year period. The estimated payments to the new plan in 2006 are approximately $0.5 million. At December 31, 2005, the defined benefit obligation was $5.8 million, the fair value of the plan assets was $2.6 million, the unrecognized net loss was $0.1 million, and the company's net pension liability was $3.1 million. From the acquisition date, the pension liability increased $62,000. RESULTS OF OPERATIONS YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 (ALL AMOUNTS IN TABLES, OTHER THAN PERCENTAGES, ARE IN THOUSANDS) REVENUES

APG began operations with the purchase of MAXRAD in January 2004. Revenues were supplemented in the fourth quarter with the acquisition of several product lines from Andrew Corporation in October 2004. APG revenue was $54.3 million in 2005, an increase of 105% from 2004. The increase in 2005 is attributable to organic MAXRAD product growth (28% year over year increase), having the product lines from Andrew Corporation for the full fiscal year (increase of approximately $18.0 million in 2005), and the addition of the Sigma products ($4.0 million) since July 2005. The chronological revenue trend by quarter within the year was $10.3, $13.4, $15.3 and $15.3 million. Emerging technology applications such as broadband wireless, in building wireless, GPS and Mobile SATCOM are the drivers of growth in this segment. The land mobile radio (LMR) and on-glass mobile antenna products represent mature markets. RFSG revenue was $14.3 million in 2005, 33.2% higher than 2004. This segment benefited from increased roll out of UMTS networks and the related need for 3G and triband scanners. Revenue was $10.8 million in 2004, up 34% from 2003. The 2004 growth was driven by the full year impact of owning RFSG, which was purchased in March 2003, and the full year impact of the CLARIFY(TM) product line, which was introduced in the fourth quarter of 2003. MSG revenue was $6.9 million in 2005, 35% higher than 2004. The MSG market is in the initial market stages in terms of the number of subscribers with the carrier customer base. Revenue was $5.1 million in 2004, 227% higher than 2003. The revenue growth in 2005 and 2004 was driven by an increase in the number of 24

carrier customers and an increase in their subscriber bases. The company's MSG Revenue in fiscal 2003 was characterized by initial customization fees and initial block purchases of roaming client licenses. Licensing revenue was $2.3 million in 2005, down 61.4% from 2004. Licensing revenue declined during each of the past two years due to the completion of older licensing agreements related to the modem technology. In 2005, the company recorded license revenue from U.S. Robotics of $0.5 million as part of the patent infringement settlement. In 2003, Intel purchased a perpetual license for the company's patented technology for $13.5 million. Absent resolution to the litigations with Agere and Lucent, licensing revenue is expected to continue to shrink in 2006. Modem product revenue ceased in 2003 with the sale of the HSP product line to Conexant. Intercompany sales from APG to RFSG are eliminated in consolidation. It is expected that intercompany sales will continue to be insignificant in 2006. GROSS PROFIT

Gross profit as a percentage of total revenue was 47.4% in 2005, 65.6% in 2004, and 74.4% in 2003. The decline in margin is due to changes in the product mix. The company's product segments vary significantly from each other in gross profit percent. The mix in 2005 was driven by the increase in APG revenue. The percentage of APG revenue to total company revenues increased from 0% in 2003, to 55% in 2004, to 70% of the company's revenues in 2005. There was also no favorable impact from modems in 2005. The gross profit included favorable cost reserve recoveries related to modems of $3.2 million in 2004 and $1.8 million in 2003. Additionally, 2003 gross profit included a $13.5 million benefit from a one-time licensing settlement with Intel. Gross profit as a percentage of revenue for APG was 32.5% in 2005, 7.7% lower than 2004. The decline in margin in 2005 was due to the impacts of the product lines acquired from Sigma and from Andrew Corporation compared to legacy MAXRAD products. The 2005 group margin impact from the Sigma product lines was 3.0% for the year. Sigma product margins negatively impacted the segment because of underutilized capacity. The 2005 group margin impact on the product lines acquired from Andrew Corporation was 5%. The company has not yet realized lower costs from transitioning the product lines from Andrew Corporation. The chronological trend by quarter within the year was 34.4%, 36.2%, 31.9%, and 28.3%. The gross margin in 2004 was related to the MAXRAD products only. The company expects the gross profit in this segment to be between 33% and 35% in 2006. Gross profit as a percentage of revenue for RFSG was 71.8% in 2005, 66.7% in 2004, and 75.0% in 2003. The increase in percentage in 2005 is attributed to the higher revenues and a heavier mix of software in 2005. The company expects long-term gross profit in this segment to be between 67% and 72%. 25

Gross profit as a percentage of revenue for MSG was 97.7% in 2005, 96.2% in 2004 and 94.3% in 2003. The cost of goods sold in the segment relates primarily to third party licenses included in the Roaming Client product. The company expects long-term gross profit in this segment to be between 96% and 99%. Gross profit as a percentage of revenue for Licensing was 96.4% in 2005, 95.9% in 2004, and 99.9% in 2003. The company expects long-term gross profit in this segment to be between 96% and 99%. There was no modem activity in 2005. While there was no modem segment revenue in 2004, the fourth quarter 2004 gross profit included a $3.2 million reversal of a modem royalty expense reserve made possible by the settlement of the company's patent litigation with 3Com. The company does not expect any further adjustments going forward related to the modem segment. Gross profit for modems as a percentage of revenue was 45.5% in 2003 which included a favorable inventory reserve recovery of $1.8 million. Without those reserve recoveries, normalized gross profit would have been 35.2% in 2003. RESEARCH AND DEVELOPMENT

2005 2004 2003 ------- ------ ------ Research and development.................................. $10,015 $8,614 $7,895 Percentage of revenues.................................... 12.9% 17.9% 17.3% % change from prior period................................ 16.3% 9.1% (22.1)%
Research and development expenses include costs for software and hardware development, prototyping, certification and pre-production costs. All costs incurred prior to establishing the technological feasibility of computer software products to be sold are research and development costs and expensed as incurred in accordance with FAS 86. No significant costs have been incurred subsequent to determining the technological feasibility. Research and development expenses increased $1.4 million from 2004 to 2005. For the year ended December 31, 2005 compared to the year ended December 31, 2004, expenses increased approximately $0.9 million related to the acquisition of the antenna product lines from Andrew Corporation and increased approximately $0.5 million related to Sigma. The increase from 2003 to 2004 is attributed to investment in the development of wireless products, net of the decrease for HSP modem products, which were sold to Conexant in 2003. The primary increase in 2004 was $1.3 million related to MAXRAD and the antenna products purchased from Andrew. Employees in Research and development at December 31, 2003, 2004 and 2005 were 50, 66 and 69. SALES AND MARKETING
2005 2004 2003 ------- ------- ------ Sales and marketing...................................... $13,074 $11,247 $7,725 Percentage of revenues................................... 16.8% 23.3% 16.9% % change from prior period............................... 16.2% 45.6% (1.2)%
Sales and marketing expenses include costs associated with the sales and marketing employees, sales representatives, product line management, and trade show expenses. Sales and marketing expenses increased $1.8 million from 2004 compared to 2005. The increase is due to impact of the APG acquisitions and restricted stock amortization, offsetting decreases from the closure of the Milpitas, California office and reduction of other corporate expenses. The full year impact of the product lines from Andrew Corporation (approximately $1.8 million higher), the addition of Sigma, (approximately $0.8 million), increases in restricted stock amortization (approximately $0.5 million) offset the decreases from restructuring and other corporate reductions (approximately $1.3 million). Sales and marketing expenses increased $4.0 million from 2003 to 2004. The increase is attributed to investment in wireless products, net of the decrease for HSP modem products, which were sold to Conexant in 26

2003. The primary increase in 2004 was $3.8 million related to MAXRAD and the antenna products purchased from Andrew in 2004. Employees in Sales and marketing at December 31, 2003, 2004, and 2005 were 21, 33 and 40. GENERAL AND ADMINISTRATIVE

2005 2004 2003 ------- ------- ------- General and administrative.............................. $16,836 $15,416 $11,036 Percentage of revenues.................................. 21.7% 32.0% 24.2% % change from prior period.............................. 9.2% 39.7% 89.1%
General and administrative expenses include costs associated with the general management, finance, human resources, information technology, legal, insurance, public company costs, and other operating expenses to the extent not otherwise allocated to other functions. General and administrative expenses increased $1.4 million from 2004 to 2005. The increase is due to impact of the APG acquisitions and restricted stock amortization, offsetting decreases from the reduction of corporate expenses. The full year impact of the product lines from Andrew Corporation (approximately $0.9 million higher), the addition of Sigma, (approximately $0.6 million), increases in restricted stock amortization (approximately $1.8 million) offset the decreases from restructuring and other corporate reductions (approximately $1.9 million). The increase in restricted stock amortization is driven by the company's decision to emphasize the use of restricted shares as equity incentives in 2005. General and administrative expenses increased $4.4 million from 2003 to 2004. The primary reasons for the increase are the inclusion of Maxrad and the antenna product lines from Andrew, Sarbanes-Oxley compliance costs, and increased costs of patent infringement litigation. Legal expenses increased $0.6 million to $3.7 million in 2004, largely related to the intellectual property litigation and the Frazier lawsuit. Sarbanes-Oxley compliance costs were approximately $1.0 million. Employees in General and administrative functions at December 31, 2003, 2004 and 2005 were 21, 53 and 70. ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT
2005 2004 2003 ----- ----- ------ Acquired in-process research and development................ $ -- $ -- $1,100 Percentage of revenues...................................... -- -- 2.4%
There was no purchased in-process technology that had not yet reached technological feasibility and had no alternative future use as part of the Sigma acquisition during July 2005 or the acquisitions during 2004 (MAXRAD acquisition in January 2004 and the acquisition of the product lines from Andrew Corporation in October 2004). Upon completion of the DTI (now RFSG) acquisition in 2003, the company expensed $1.1 million representing purchased in-process technology. AMORTIZATION OF OTHER INTANGIBLE ASSETS
2005 2004 2003 ------ ------ ------ Amortization of other intangible assets.................... $4,137 $2,972 $1,124 Percentage of revenues..................................... 5.3% 6.2% 2.5%
The base amount of amortization of intangible assets in 2003 relates to the acquisition of cyberPIXIE in 2002 and the acquisition of DTI in 2003. The increase from 2003 to 2004 relates to the acquisitions of MAXRAD and the antenna product lines from Andrew (now collectively APG). The increase from 2004 to 2005 relates to the amortization for the full year impact of the product lines from Andrew Corporation ($0.8 million) and the acquisition of Sigma ($0.8 million). 27

On July 4, 2005, the company purchased all of the outstanding shares of Sigma. Sigma is based in Dublin, Ireland and develops, manufactures and distributes antenna products designed for public safety and for the UMTS cellular networks. Sigma employs approximately 87 people in Ireland and the United Kingdom. The Sigma acquisition expands the company's product lines within its APG segment. With the acquisition of Sigma, the company gains entry into the growing cellular base station antenna market and also gains a geographic footprint in Europe. In exchange for all of the outstanding shares of Sigma, the company paid cash consideration of 19.4 million Euro (approximately $23.1 million), plus assumed an unfunded pension obligation of approximately 2.5 million Euro (approximately $3.0 million), and incurred approximately 1.7 million Euro (approximately $2.0 million) in transaction costs. In addition to the cash consideration at closing, the selling stockholders of Sigma may earn up to an additional 7.5 million Euro (approximately $9.1 million) in cash based on Sigma's revenue performance over the 18-month period ending December 31, 2006. The total purchase price of 23.6 million Euro (approximately $28.2 million) was allocated $8.2 million to tangible assets acquired, $7.8 million to liabilities assumed, $2.5 million to core technology, $6.4 million to customer relationships, and $0.1 million to order backlog in the accompanying consolidated balance sheets. The intangible assets have a weighted average amortization period of 6.0 years. The $15.7 million excess of the purchase price over the fair value of the net tangible and intangible assets was allocated to goodwill. The company will amortize the order backlog over one year and the other intangible assets over six years. In October 2004, the company completed the acquisition of selected assets associated with Andrew Corporation's mobile antenna business for a total of $10.9 million in cash. The assets acquired consist of Andrew's GPS, Mobile SATCOM, On-Glass, and Antenna Specialists(R) brand of professional antenna products. The results of operations of Andrew are included in the financial statements from the date of acquisition. These product lines were integrated into the operations of PCTEL's Antenna Products Group. Since the purchase price exceeds the net tangible assets acquired, the difference is recorded as excess purchase price and allocated to goodwill and other intangible assets. The purchase price was allocated $5.4 million to net tangible assets acquired, $0.6 million to core technology, $2.6 million to customer relationships, $0.3 million to trademarks and $0.3 million to order backlog and other intangible assets, net, in the accompanying consolidated balance sheets. The $1.7 million excess of the purchase price over the fair value of the net tangible and intangible assets was allocated to goodwill. Intangible assets will be amortized over an estimated useful life of six and eight years. In January 2004, the company completed the acquisition of MAXRAD, Inc. (now the Antenna Product Group). MAXRAD is a manufacturer of wireless communications antennas for broadband wireless, in-building wireless and land mobile radio applications. In connection with the acquisition, PCTEL acquired all of the outstanding capital stock of MAXRAD. In exchange for the outstanding capital stock of MAXRAD, PCTEL paid $18.2 million, net of cash acquired of $2.4 million, out of the available working capital. The results of operations of MAXRAD are included in the financial statements from the date of acquisition. Since the purchase price exceeds the net tangible assets acquired, the difference is recorded as excess purchase price and allocated to goodwill and other intangible assets. The purchase price of $20.6 million in cash, of which $0.4 million was paid in April 2004, was allocated $7.6 million to net tangible assets acquired, $0.9 million to the covenant not to compete, $1.3 million to core technology, $3.2 million to customer lists, $1.4 million to trademarks and $0.1 million to other intangible assets, net, in the accompanying consolidated balance sheets. The $6.1 million excess of the purchase price over the fair value of the net tangible and intangible assets was allocated to goodwill. The covenant not to compete will be amortized over two years and other intangible assets over an estimated useful life of six and eight years. In March 2003, the company acquired the assets of DTI for a total of $11.0 million in cash (now the RF Solutions Group). The results of operations of DTI are included in the financial statements from the date of acquisition. Since the purchase price exceeded the net tangible assets acquired, the difference is recorded as excess purchase price and allocated to in-process research and development, goodwill and other intangible assets. The purchase price was allocated to the assets acquired and liabilities assumed at their estimated fair values on the date of acquisition as determined by an independent valuation firm. The purchase price was allocated $2.3 million to net assets acquired, $1.1 million to acquired in-process research and development, $0.2 million to the covenant not to compete and $4.4 million to other intangible assets, net, in the 28

accompanying consolidated balance sheets. The $3.0 million excess of the purchase price over the fair value of the net tangible and intangible assets was allocated to goodwill. In-process research and development was expensed, but the covenant not to compete is being amortized over two years, and other intangible assets over an estimated useful life of four years. As part of an earn-out arrangement, the company paid $1.5 million to DTI in 2004. RESTRUCTURING CHARGES

2005 2004 2003 ---- ---- ------ Restructuring charges....................................... $(70) $(66) $3,462 Percentage of revenues...................................... (0.1)% (0.1)% 7.6%
2005 restructuring activity consisted of a $0.1 million favorable adjustment to the reserve related to the 2003 sale of the HSP modem product line based on a final negotiation of the California lease liability. 2004 restructuring activity consisted of $0.2 million favorable adjustments to reserves related to the 2003 sale of the HSP modem product line, offset by $0.1 million of expense related to the discontinuation of the Soft AP product line. The company's 2003 restructuring charge totaled $3.5 million. It consisted of severance and employment related costs of $1.9 million and costs related to closure of excess facilities as a result of the reduction in force of $1.6 million. $3.3 million of the total related to the sale of the company's HSP modem product line to Conexant. A total of 26 employees, both foreign and domestic, were terminated subsequent to the sale of the soft modem product line to Conexant in May 2003 along with the related facilities closures. GAIN ON SALE OF ASSETS AND RELATED ROYALTIES
2005 2004 2003 ------ ------ ------ Gain on sale of assets and related royalties............... $2,100 $2,000 $5,476 Percentage of revenues..................................... 2.7% 4.1% 12.0%
In May 2003, the company completed the sale of certain of its assets to Conexant Systems, Inc., ("Conexant"). In exchange for the assets acquired from the company, Conexant delivered approximately $10.75 million in cash to the company, which represents $8.25 million plus the book value of the acquired inventory and fixed assets being transferred to Conexant. Conexant assumed certain liabilities of the company. The total proceeds of $10.75 million netted a gain on sale of assets of $4.5 million. Concurrently with the completion of the asset transaction with Conexant, PCTEL and Conexant also completed an Intellectual Property Assignment Agreement ("IPA") and Cross-License Agreement. PCTEL provided Conexant with a non-exclusive, worldwide license to certain of PCTEL's soft modem patents. In consideration for the rights obtained by Conexant from PCTEL under this agreement, and taking into account the value of patent rights obtained by PCTEL from Conexant under this agreement, during the period beginning on July 1, 2003 and ending on June 30, 2007, Conexant agreed to pay to PCTEL, on a quarterly basis, royalties in the amount of ten percent (10%) of the revenue received during the royalty period, up to a maximum amount of $0.5 million per quarter with respect to each calendar quarter during the royalty period, contingent upon sales by Conexant during the period. Future payments by Conexant to PCTEL in connection with the IPA will be recorded as part of the gain on sale of assets and related royalties in the statement of operations. The company received $2.0 million of royalty payments from Conexant during 2005 and 2004. The company amended the cross license agreement with Conexant in August 2005. The period for which the royalties are payable was extended to end on June 30, 2009. The quarterly royalty maximum was amended to be $250,000 per quarter from January 1, 2006 through December 31, 2007 and $200,000 per quarter from January 1, 2008 through June 30, 2009. In 2005, the Company also recorded $0.1 million related to the sale of intellectual property from the RFS segment. 29

OTHER INCOME, NET

2005 2004 2003 ------ ------ ------ Other income, net.......................................... $1,547 $1,261 $1,383 Percentage of revenues..................................... 2.0% 2.6% 3.0%
Other income, net, consists primarily of interest income. Interest income is expected to fluctuate over time with changes in interest rates and size of the company's cash and cash equivalent balances. Despite lower cash balances in 2005, other income, net, increased from 2004 to 2005 due to higher interest rates. The company used cash of $25.2 million for the acquisition of Sigma. Other income, net declined from 2003 to 2004 due to declining interest rates over the periods and the use of cash for acquisitions for the stock buy back program. The company used cash of $29.1 million for acquisitions and $4.3 million for stock buy backs in 2004. PROVISION (BENEFIT) FOR INCOME TAXES
2005 2004 2003 ---- ----- ------ Provision (benefit) for income taxes........................ $235 $(541) $2,575 Effective tax rate.......................................... (6.8)% (16.5)% 30.5%
Significant management judgment is required to assess the likelihood that the company's deferred tax assets will be recovered from future taxable income. The company maintained a full valuation allowance against all the deferred tax assets since 2001, as a result of uncertainties regarding realizability. A valuation allowance of $13.8 million was established at December 31, 2005 because the company's believes it is more likely than not that the company will not realize the benefit of certain deferred tax assets. The valuation allowance increased $1.9 million in 2005. Certain deferred tax assets relate to (i) restricted stock and (ii) excess deductions on non-qualified stock option exercises. In accordance with SFAS No. 109, "Accounting for Income Taxes", upon reversal of the valuation allowance against these deferred tax assets, $0.1 million of the decrease in the valuation allowance will be recognized as a credit to additional paid-in capital and $0.1 million of the increase in the valuation allowance will be recognized as a charge to additional paid-in capital. In 2005, a valuation allowance of $0.3 million was established in purchase accounting for Sigma as the Company's management believes is more likely than not the Company will not realize the benefits of Sigma's deferred tax asset. In accordance with SFAS No. 109, upon reversal of the valuation allowance against this deferred tax asset, $0.3 million will be recognized as a reduction to goodwill in connection with the Sigma acquisition. The effective tax rate differed from the statutory federal rate of 35% during 2005 principally due to an increase in the valuation allowance for deferred tax assets, different rates for foreign income and losses, and revisions made by management to other deferred tax assets. During the fourth quarter 2005, the company changed its estimate regarding the character in taxation of certain leasing income received in 2004 for one of its Israeli subsidiaries. As a result, the company reversed the tax expense it booked in 2004 to reflect the change in estimate regarding its filing position. The increase in the deferred tax valuation allowance was primarily consisted of an increase in the deferred tax asset related to net operating losses. The effective tax rate was below the statutory federal rate of 35% during 2004 principally due to permanent differences including adjustments to the deferred tax valuation allowance. The effective tax rate was below the statutory tax rate of 35% during 2003 primarily due to the recognition of benefits relating to tax credits for research and development activities. 30

LIQUIDITY AND CAPITAL RESOURCES

2005 2004 2003 -------- -------- -------- Net cash provided by (used in) operating activities......................................... $ (324) $ (7,424) $ 17,417 Net cash provided by (used in) investing activities......................................... (25,171) (15,538) 32,788 Net cash provided by financing activities............ 682 824 2,786 Cash, cash equivalents and short-term investments at the end of year.................................... 58,966 83,887 125,184 Working capital at the end of year................... 69,695 87,771 112,689
The company used $0.3 million of net cash from operating activities in 2005. The company used $3.8 million related to a reduction in accrued liabilities, primarily for the payment of transition services-related costs with Andrew Corporation ($2.6 million) , $0.7 million for retention bonuses and $0.6 million for the earnout for the DTI acquisition. The company also used $1.3 million in cash from growth in accounts receivable which was driven by the increase in sales in the fourth quarter 2005 compared to the fourth quarter 2004. Inventories declined $1.5 million due to the transition of the Andrew product lines into the APG operations, and also due to inventory reductions with RFSG. The cash used from operating activities declined by $7.1 million in 2005 compared to 2004 which included uses of cash of $4.9 million for receivables, $3.2 million for royalties, and $1.7 million for income taxes in 2004. In 2003, the company's operating activities provided cash of $17.4 million due to higher net income ($5.9 million) and positive cash from changes in prepaids and other assets ($6.1 million) and accounts receivable ($3.0 million). The company used $25.2 million in its investing activities in 2005, primarily for the Sigma acquisition ($25.2 million). The company used $4.3 million for capital expenditures but received $2.2 million in proceeds on sale of fixed assets and $2.1 million related to the sale of assets and related royalties related to Conexant. In 2004, the company used $15.5 million of net cash in its investing activities. The largest uses of cash flow were for the acquisitions of MAXRAD ($18.2 million) and the acquisition of the Andrew product lines ($10.9 million) and an earn-out payment made in connection with the DTI acquisition of 2003 ($1.5 million). Additionally, the company used $6.1 million for capital expenditures, $4.9 million of which was the purchase of the larger building for the Antenna Products Group. In 2003, investing activities related to the sale of the modem business ($11.7 million) and the sale of investments ($32.7 million) offset the use of cash for the DTI acquisition ($10.7 million). Cash flow from financing activities was $0.7 million in 2005. Financing activities included $1.7 million of proceeds from issuance of common stock related to stock option exercises offset by $0.8 million used to repurchase the company's common stock pursuant to its share buyback program. The company received $5.1 million in proceeds from issuance of common stock related to stock options offset by $4.3 million for the repurchase of the company's common stock in 2004. Cash from financing activities generated $2.8 million in cash in 2003 due to proceeds from issuance of common stock ($8.9 million) offsetting use of cash for repurchase of the company's stock ($6.2 million). The decrease in cash and cash equivalents of $24.8 million in 2005 was $2.6 million more than the decrease in cash and cash equivalents of $22.1 million in 2004. The higher decrease in cash in 2005 compared to 2004 is because the company used less use of cash from operations ($7.2 million better), less cash for acquisitions ($3.9 million lower); 2004 cash flow included the sale of short-term investments ($19.1 million proceeds). The decrease in cash and cash equivalents of $22.1 million in 2004 compared to a increase of cash and cash equivalents of $13.8 million in 2003 is due to increase in amounts paid for acquisitions (increase of $18.3 million), the working capital associated with the acquisitions, and lower proceeds from royalties ($9.7 million lower). As of December 31, 2005, the company had $59.0 million in cash and cash equivalents and working capital of $69.7 million. Accounts receivable, as measured in days sales outstanding (DSO), was 64 and 81 days at December 31, 2005 and 2004, respectively. The company has targeted to reduce the days outstanding to 50 or lower for 2006. 31

The company believes that the existing sources of liquidity, consisting of cash, short-term investments and cash from operations, will be sufficient to meet the working capital needs for the foreseeable future. The company will continue to evaluate opportunities for development of new products and potential acquisitions of technologies or businesses that could complement the business. The company may use available cash or other sources of funding for such purposes. CONTRACTUAL OBLIGATIONS AND COMMERCIAL COMMITMENTS The following summarizes the contractual lease obligations for office and product assembly facilities, motor vehicles, and equipment and the effect such obligations are expected to have on the liquidity and cash flows in future periods (in thousands):

LESS THAN AFTER TOTAL 1 YEAR 1-3 YEARS 4-5 YEARS 5 YEARS ------ --------- --------- --------- ------- Contractual obligations Leases.............................. $5,287 $1,099 $2,629 $1,016 $543 Purchase commitment................. 180 180 -- -- -- Pension payments.................... 515 515 -- -- -- ------ ------ ------ ------ ---- 5,982 1,794 2,629 1,016 543
These obligations for leases include $128,000 related to capital leases for motor vehicles and manufacturing equipment in Dublin, Ireland. In the quarter ending March 2006, the company will determine the disposition of the leased space on Wisteria Drive in Germantown, Maryland. The company has a remaining firm purchase contract for $180,000 with an RFSG software supplier. The quantity committed represents the lifetime requirements for this software. The company has no other firm inventory purchase contract commitments with major suppliers beyond near term needs. The company has obligations related to the PCTEL Europe Pension Scheme of $515,000 in 2006 (see footnote 15 on benefit plans). In addition to the cash consideration at closing of the Sigma acquisition, the selling stockholders of Sigma may earn up to an additional 7.5 million Euro (approximately $9.1 million) in cash based on Sigma's revenue performance over the 18-month period ending December 31, 2006. The company believes that a payout in 2006 for Sigma's revenue performance is unlikely. RECENT ACCOUNTING PRONOUNCEMENTS In March 2005, the Securities and Exchange Commission ("SEC") issued Staff Accounting Bulletin ("SAB") No. 107, which provides guidance on the implementation of Statement of Financial Accounting Standards ("SFAS") No. 123(R), "Share-Based Payment" (see discussion below). In particular, SAB No. 107 provides key guidance related to valuation methods (including assumptions such as expected volatility and expected term), the accounting for income tax effects of share-based payment arrangements upon adoption of SFAS No. 123(R), the modification of employee share options prior to the adoption of SFAS No. 123(R), the classification of compensation expense, capitalization of compensation cost related to share-based payment arrangements, first-time adoption of SFAS No. 123(R) in an interim period, and disclosures in Management's Discussion and Analysis subsequent to the adoption of SFAS No. 123(R). SAB No. 107 became effective on March 29, 2005. The Company will apply the principles of SAB 107 in conjunction with its adoption of SFAS 123(R) in the quarter ending March 31, 2006. In May 2005, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 154, "Accounting Changes and Error Corrections", a replacement of APB Opinion No. 20 and FASB Statement No. 3. This statement applies to all voluntary changes in accounting principle, and requires retrospective application to prior periods' financial statements for changes in 32

accounting principle. SFAS No. 154 will be effective for the company beginning in fiscal year 2007. The company does not believe this statement will have a material impact on the company's financial statements. In December 2004, the Financial Accounting Standards Board ("FASB") issued FAS No. 123R, "Share-Based Payment". The statement addresses the accounting for transactions in which an enterprise receives employee services in exchange for (a) equity instruments of the enterprise or (b) liabilities that are based on the fair value of the enterprises equity instruments or that may be settled by the issuance of such equity instruments. FAS No. 123R is effective no later than annual reporting periods ending after June 15, 2005. The company will adopt FAS No. 123R on a prospective basis starting in the first quarter of fiscal 2006. The company estimates that the 2006 impact of adopting SFAS No. 123(R) will be approximately $1.0 million to $1.5 million before income taxes, which approximates the annual 2005, 2004 and 2003 pro forma stock-based compensation expense for stock options. The actual cost will differ from this range due to changes in assumptions. This estimated range primarily reflects the impact of expensing stock options for the first time. In January 2005, the company approved the acceleration of vesting for all unvested underwater options in order to mitigate the associated future share-based compensation expense under SFAS 123(R). The company accelerated the vesting of "out of the money" options with a share price equal to or greater than $10.00. Under FAS 123R, the acceleration of these options will result in PCTEL not being required to recognize share-based compensation expense of approximately $3.8 million beginning in the company's quarter ending March 31, 2006 and through the company's quarter ending March 31, 2008. See footnote 10 in the Notes to the Financial Statements. In December 2004, the FASB issued Staff Positions in relation to FAS No. 109, "Accounting for Income Taxes". FASB issued FSP FAS 109-1, "Application of FASB Statement No. 109, Accounting for Income Taxes, to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004". As a domestic manufacturer, the company will access early in 2006 whether the company is eligible for any tax deductions under this Act. FASB issued FSP FAS 109-2, "Accounting and Disclosure Guidance for the Foreign Repatriation Provision within the American Jobs Creation Act of 2004. At this time the company does not expect to repatriate the earnings of our foreign subsidiaries as dividends to take advantage of this tax credit. In November 2004, the FASB issued FAS No. 151, "An Amendment of ARB No. 43, Chapter 4". The statement amends the guidance in ARB No. 43, Chapter 4, "Inventory Pricing," to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). FAS No. 151 is effective for inventory costs incurred during fiscal years beginning after June 15, 2005. The company will adopt FAS 151 in fiscal 2006. Adoption of FAS No. 151 is not expected to have a material effect on the ongoing operations of the company. ITEM 7A: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The company is exposed to market risk from changes in interest rates and foreign exchange rates. INTEREST RATE RISK We manage the sensitivity of our results of operations to credit risks and interest rate risk by maintaining a conservative investment portfolio. The primary objective of our investment activities is to preserve principal without significantly increasing risk. To achieve this objective, we maintain our portfolio of cash equivalents in money market funds, which are fixed at $1 per share and for which only the yield fluctuates. Due to changes in interest rates, our future investment income may fall short of expectations, Since the company invests in money market funds, we have no unrealized holding gains or losses as of December 31, 2005 and 2004, respectively. A hypothetical increase or decrease of 10% in market interest rates would not result in a material decrease in interest income earned through maturity on investments held at December 31, 2005. We do not hold or issue derivative, derivative commodity instruments or other financial instruments for trading purposes. 33

FOREIGN CURRENCY RISK We are exposed to currency fluctuations, as we sell our products internationally. We manage the sensitivity of our international sales by denominating the majority of transactions in U.S. dollars. Beginning in July 2005, our results include commercial activity by Sigma. Sigma transactions are denominated primarily in pounds sterling and Euros. If the United States dollar uniformly increased or decreased in strength by 10% relative to the currencies in which our sales were denominated, our net loss would not have changed by a material amount for the six months ended December 31, 2005. For purposes of this calculation, we have assumed that the exchange rates would change in the same direction relative to the United States dollar. Our exposure to foreign exchange rate fluctuations, however, arises in part from translation of the financial statements of foreign subsidiaries into U.S. dollars in consolidation. As exchange rates vary, these results, when translated, may vary from expectations and adversely impact overall expected profitability. The effect of foreign exchange rate fluctuation gains for the years ended December 31, 2005 and 2004 was negative $168,000 and positive $83,000, respectively. 34

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Shareholders of PCTEL, Inc.: We have completed integrated audits of PCTEL, Inc.'s 2005 and 2004 consolidated financial statements and of its internal control over financial reporting as of December 31, 2005, and an audit of its 2003 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below. Consolidated financial statements and financial statement schedule In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of PCTEL Inc. and its subsidiaries at December 31, 2005 and 2004, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2005 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of financial statements includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. Internal control over financial reporting Also, we have audited management's assessment, included in Management's Report on Internal Control Over Financial Reporting appearing under Item 9A, that PCTEL, Inc. did not maintain effective controls over the review, completeness and accuracy of its provision for income taxes and the related financial statement presentation and disclosure of income tax matters based on criteria established in Internal Control -- Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management's assessment and on the effectiveness of the Company's internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions. A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and 36

directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. As of December 31, 2005, the Company did not maintain effective controls over the review, completeness and accuracy of its provision for income taxes and the related financial statement presentation and disclosure of income tax matters. This control deficiency resulted in audit adjustments to the 2005 annual consolidated financial statements with respect to income tax disclosures and the 2005 second quarter consolidated financial statements with respect to the provision for income taxes. In addition, this control deficiency could result in a misstatement of the income tax provision and income tax related financial statement disclosures that would result in a material misstatement of the annual or interim financial statements that would not be prevented or detected. Accordingly, management has concluded that this control deficiency constitutes a material weakness. This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2005 consolidated financial statements, and our opinion regarding the effectiveness of the Company's internal control over financial reporting does not affect our opinion on those consolidated financial statements. As described in Management's Report on Internal Control Over Financial Reporting, management has excluded Sigma Wireless Technologies ("Sigma"), from its assessment of internal control over financial reporting as of December 31, 2005 because it was acquired by the Company through a purchase business combination in July 2005. We have also excluded Sigma from our audit of internal control over financial reporting. Sigma is a wholly owned subsidiary of the Company that represents 21% of consolidated total assets and 5% of consolidated revenues, respectively, as of and for the year ended December 31, 2005. In our opinion, management's assessment that PCTEL, Inc. did not maintain effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on criteria established in Internal Control -- Integrated Framework issued by the COSO. Also, in our opinion, because of the effect of the material weakness described above on the achievement of the objectives of the control criteria, PCTEL, Inc. has not maintained effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control -- Integrated Framework issued by the COSO.

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FOR THE YEAR ENDED: DECEMBER 31, 2005 NOTE 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES NATURE OF OPERATIONS PCTEL was incorporated in California in 1994 and reincorporated in Delaware in 1998. PCTEL provides wireless connectivity products and technology to wireless carriers, aggregators of Internet connectivity, wireless Internet service providers (WISP's), PC OEM's, and wireless equipment manufacturers. The company brings together expertise in RF platform design, mobility software, and hardware. PCTEL simplifies mobility, provides wireless intelligence, and enhances wireless performance. Additionally, the company licenses both patented and proprietary access technology, principally related to analog modems, to modem solution providers. The company principally operates in four business segments. Antenna Products Group The Antenna Products Group (APG) product line consists of wireless communication antennas designed to enhance the performance of broadband wireless, in-building wireless, wireless Internet service providers and Land Mobile Radio (LMR) applications. The Antenna Products Group was formed around the business of MAXRAD, Inc, which was acquired in January 2004. As a result of the October 2004 acquisition of certain antenna product lines from Andrew Corporation ("Andrew"), APG expanded the product line to include GPS (Global Positioning Systems), satellite communications (Mobile SATCOM) and on-glass mobile antennas. In July 2005, the company again expanded the product line with the purchase of Sigma Wireless Technologies ("Sigma" or "SWT"), located in Dublin, Ireland. Sigma provides integrated variable electrical tilt base stations antennas (iVET), Public Mobile Radio (PMR), and Digital Public Mobile Radio (DPMR) antenna products. RF Solutions Group The RF Solutions Group (RFSG) product line consists of software-defined radio products designed to measure and monitor cellular networks. The RF Solutions Group was formed around the business of DTI, Inc., which was acquired in March 2003. The technology is sold in three forms; as OEM radio frequency receivers, as integrated systems solutions, and as components and systems to U.S. government agencies. Mobility Solutions Group The Mobility Solutions Group (MSG) produces Wi-Fi and Cellular Mobility Software products. This family of solutions simplifies access to both wired and wireless data networks. Licensing PCTEL has an intellectual property portfolio consisting of over 130 U.S. patents and applications, primarily in analog modem technology. It also has proprietary DSP based embedded modem technology. Independent of the three product lines, the company has an active licensing program designed to monetize its intellectual property. BASIS OF CONSOLIDATION AND FOREIGN CURRENCY TRANSLATION The company uses the United States dollar as the functional currency for the financial statements. The company uses the local currency as the functional currency for its subsidiaries in China (Yuan), Ireland (euro), and Japan (Yen). Assets and liabilities of these operations are translated to U.S. dollars at the exchange rate in effect at the applicable balance sheet date, and revenues and expenses are translated using 42

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 average exchange rates prevailing during that period. Translation gains (losses) are recorded in accumulated other comprehensive income as a component of stockholders' equity. All gains and losses resulting from other transactions originally in foreign currencies and then translated into U.S. dollars are included in net income. At December 31, 2005 the cumulative translation adjustment was negative $168,000. The company uses the U.S. dollar as the functional currency for its subsidiaries in Israel and for its branch office in Hong Kong. These consolidated financial statements include the accounts of PCTEL and its subsidiaries after eliminating intercompany accounts and transactions. USE OF ESTIMATES The preparation of 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 periods reported. Actual results could differ from those estimates. RECLASSIFICATIONS Certain previously reported amounts have been reclassified to conform to the current period presentation. CASH AND CASH EQUIVALENTS Financial instruments are divided into two different classifications: Cash equivalents: Money market funds that have an original maturity of 90 days or less. Restricted cash: Certificates of deposit that support a stand-by letter of credit in connection with facility lease obligations and are restricted for use by the company. The carrying amounts reported for cash equivalents is considered to approximate fair values based upon the short maturities of these financial statements. CONCENTRATIONS OF CREDIT RISK AND OTHER RISKS AND UNCERTAINTIES The company is subject to certain risks including the impact of the continued economic slowdown, the company's ability to develop and successfully introduce new and enhanced products such as wireless products, the outcome of potential litigation involving intellectual property, competition from larger, more established companies and dependence on key suppliers. Financial instruments that potentially subject the company to credit risk consist primarily of trade receivables. There were no short-term investments at December 31, 2005. The company maintains a portfolio of cash equivalents with reputable financial institutions and money market funds. For trade receivables, credit risk is the potential for a loss due to a customer not meeting its payment obligations. PCTEL customers are concentrated in the wireless industry. Estimates are used in determining an allowance for amounts, which the company may not be able to collect, based on current trends, the length of time receivables are past due and historical collection experience. Provisions for and recovery of bad debts are recorded against sales and marketing expense in the consolidated statements of operations. The company performs ongoing evaluations of customers' credit limits financial condition and generally require no collateral. As of December 31, 2005, the credit risk was diversified as a result of acquisitions. One customer accounted for 16% of gross accounts receivable with the next largest balance accounting for 5%. As 43

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 of December 31, 2004, one customer accounted for 11% of gross accounts receivable with the next largest balance accounting for 6%. The market for PCTEL products is characterized by frequent transitions in which products rapidly incorporate new features and performance standards. A failure to develop products with required features or performance standards or a delay in bringing a new product to market could adversely affect the operating results. In addition, due to competitive pricing pressures that affect the products and in part to increasing component and manufacturing costs, the company expects gross margins from both existing and future products to decrease over time. INVENTORIES Inventories are stated at the lower of cost or market and include material, labor and overhead costs using the FIFO method of costing. Inventories as of December 31, 2005 were composed of raw materials, sub assemblies, finished goods and work-in-process. The company regularly monitors inventory quantities on hand and, based on the current estimated requirements, it was determined that any excess inventory was reserved as of December 31, 2005 and 2004. Due to competitive pressures and technological innovation, there may be excess inventory in the future. As of December 31, 2005 and December 31, 2004, the allowance for inventory losses was $0.9 million and $0.4 million, respectively. The company recovered $1.8 million of the former write-downs related to the modem inventory during the year ended December 31, 2003. Write-downs of inventories would have a negative impact on gross margin. Inventories consist of the following (in thousands):

DECEMBER 31, --------------- 2005 2004 ------ ------ Raw materials............................................... $6,404 $6,868 Work in process............................................. 461 131 Finished goods.............................................. 2,682 1,555 ------ ------ Inventories, net.......................................... $9,547 $8,554 ====== ======
PREPAID AND OTHER CURRENT ASSETS Prepaid assets are stated at cost and are amortized over their useful lives (up to one year) of the assets. Prepaid and other current assets consist of the following (in thousands):
DECEMBER 31, --------------- 2005 2004 ------ ------ Income tax receivable....................................... $1,363 $1,383 Prepaid expenses............................................ 877 922 Other receivables........................................... 746 558 Interest receivable......................................... 123 106 ------ ------ Prepaid and other current assets............................ $3,109 $2,969 ====== ======
PROPERTY AND EQUIPMENT Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets. The company depreciates computers over three years, office equipment and manufacturing equipment over five years, furniture and fixtures over seven years, and buildings over 44

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 30 years. Leasehold improvements are amortized over the shorter of the corresponding lease term or useful life. Gains and losses on the disposal of fixed assets are included in operating expenses. Property and equipment consists of the following (in thousands):

DECEMBER 31, ----------------- 2005 2004 ------- ------- Building.................................................... $ 5,344 $ 4,484 Land........................................................ 1,770 2,820 Computer and office equipment............................... 2,519 1,953 Manufacturing Equipment..................................... 3,585 1,847 Furniture and fixtures...................................... 817 242 Leasehold improvements...................................... 65 18 Motor Vehicles.............................................. 116 -- ------- ------- Total property and equipment.............................. 14,216 11,364 Less: Accumulated depreciation and amortization............. (3,026) (1,618) ------- ------- Property and equipment, net............................... $11,190 $ 9,746 ======= =======
Motor vehicles and manufacturing equipment includes assets under capital leases in Dublin, Ireland. Depreciation expense was approximately $1.7, $1.1 and $0.7 million for the years ended December 31, 2005, 2004 and 2003, respectively. SOFTWARE DEVELOPMENT COSTS The company accounts for software development costs in accordance with SFAS No. 86, "Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise Marketed." The company's products include a software component. To date, the company has expensed all software development costs because costs incurred subsequent to the products reaching technological feasibility were not significant. REVENUE RECOGNITION The company sells antenna products, software defined radio products, and licenses the modem technology through the licensing program. The company records the sale of these products, including related maintenance, and the licensing of the intellectual property as revenue. In accordance with SAB No. 104, the company recognizes revenue when the following criteria are met: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, price is fixed and determinable, and collectibility is reasonably assured. The company recognizes revenue for sales of the antenna products and software defined radio products, when title transfers, which is generally upon shipment from the factory. PCTEL sells these products into both commercial and secure application government markets. Title for sales into the commercial markets generally transfers upon shipment from the factory. Products that are sold into the secure application government market are generally designed to a unique specification. Title for sales into the government markets generally does not transfer until acceptance for the first units and then upon shipment thereafter. Revenue is recognized for antenna products sold to major distributors upon shipment from the factory. The company allows its major antenna product distributors to return product under specified terms and conditions. The company accrues for product returns in accordance with FAS 48, "Revenue Recognition When Right of Return Exists". 45

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 The company recognizes revenue from the Wi-Fi and cellular mobility software, including related maintenance rights, under SOP 97-2 Software Revenue Recognition. If the software license is perpetual and vendor specific objective evidence can be established for the software license and any related maintenance rights, the software license revenue is recognized upon delivery of the software and the maintenance is recorded pro-rata over the life of the maintenance rights. If part of the licensing agreement requires engineering services to customize software for the customer needs, the revenue for these services is recognized when the initial software license is delivered. If vendor specific objective evidence cannot be established, and the only undelivered item is maintenance, the software license revenue, the revenue associated with engineering services, if applicable, and the related maintenance rights are combined and recognized pro-rata over the expected term of the maintenance rights. If vendor specific evidence cannot be established on any of the non-maintenance elements, the revenue is recorded pro-rata over the life of the contractual obligation. The company records intellectual property licensing revenue when; it has a licensing agreement, the amount of related royalties is known for the accounting period reported, and collectibility is reasonably assured. Knowledge of the royalty amount specific to an accounting period is either in the form of a royalty report specific to a quarter, a contractual fixed payment in the license agreement specific to a quarter, or the pro-rata amortization of a fixed payment related to multiple quarters over those quarters using the operating lease method. If a license agreement provides for a fixed payment related to periods prior to the license effective date (the past) and volume-based royalties going forward, the fixed payment is recognized at the license effective date and the volume based royalties are recognized as royalty reports are received. If the license provides for a fixed payment for the past and for a finite future period, to be followed by volume based royalties thereafter, the fixed payment is recorded under the operating lease method and recognized pro-rata from the effective date through the end of the period covered by the fixed payment. If a one-time license payment is made for a perpetual license, with no future obligations on behalf of us, revenue is recognized under the capitalized lease method upon the effective date. There is one exception to the recognition of intellectual property licensing as revenue. The company signed a licensing agreement with Conexant simultaneously with the sale of its HSP modem product line to Conexant in 2003. Because the HSP modem product line also requires a license to the company's patent portfolio, the gain on sale of the product line and the licensing stream are not separable for accounting purposes. Ongoing royalties from Conexant are presented in the income statement as Gain on Sale of Assets and Related Royalties. WARRANTIES AND SALES RETURNS The company's APG segment allows its major distributors and certain other customers to return unused product under specified terms and conditions. In accordance with FAS 48, the company accrues for product returns based on historical sales and return trends. At December 31, 2005, the company's allowance for sales returns was $247,000. The company offers repair and replacement warranties of primarily two years for APG products and one year for RFSG products. At December 31, 2005, the company's warranty reserve was $147,000 for these products based on historical sales and costs of repair and replacement trends. R & D COSTS The company expenses research and development costs as incurred. All costs incurred prior to establishing the technological feasibility of computer software products to be sold are research and development costs and expensed as incurred in accordance with SFAS 86, "Accounting for the Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed". 46

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 ALLOWANCE FOR DOUBTFUL ACCOUNTS The company maintains an allowance for doubtful accounts for estimated uncollectible accounts receivable. The allowance is based on the company's assessment of known delinquent accounts, historical experience, and other currently available evidence of the collectability and the aging of accounts receivable. The company's total allowance for doubtful accounts was $0.3 million and $0.5 million at December 31, 2005 and December 31, 2004, respectively. The provision for doubtful accounts is included in sales and marketing expense. INCOME TAXES The company provides for income taxes under the provisions of SFAS No. 109, "Accounting for Income Taxes". SFAS No. 109 requires an asset and liability based approach in accounting for income taxes. Deferred income tax assets and liabilities are recorded based on the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates. Valuation allowances are provided against deferred tax assets, which are not likely to be realized. STOCK-BASED COMPENSATION In December 2004 the FASB issued Statement No. 123 (revised 2004), "Share-Based Payment" (SFAS No. 123(R)), which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Under SFAS 123R, the pro forma disclosure alternative permitted under FASB Statement No. 123, "Accounting for Stock-Based Compensation" (SFAS 123) and "Accounting for Stock-Based Compensation -- Transition and Disclosure" (SFAS 148) is no longer allowable. The company will adopt SFAS 123R in the quarter ending March 31, 2006; however, until then, and as currently permitted by SFAS 123 and SFAS 148, we continue to apply the accounting provisions of Accounting Principles Board Opinion Number 25, "Accounting for Stock Issued to Employees" (APB 25), and related interpretations, with regard to the measurement of compensation cost for options granted under our stock option plans. In fiscal 2005, 2004 and 2003 no compensation expense was recorded with respect to stock options granted as all options granted had an exercise price equal to the market value of the underlying common stock on the date of grant. In addition, no compensation expense was recorded for purchases under our Employee Stock Purchase Plan in accordance with APB 25. Had expense been recognized using the fair value method described in SFAS 123, using the Black-Scholes option-pricing model, we would have reported the following results of operations:

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 These costs may not be representative of the total effects on reported income (loss) for future years. Factors that may also impact future years include the attribution of the awards to the service period, the vesting period of stock awards, timing of additional grants of stock option awards and the number of shares granted for future awards. The company expects the adoption of SFAS No. 123R to have a material effect on our reported net income (loss) per share. While the company intends to continue to use stock options for employee incentives, the company plans to emphasize the use of restricted stock. The company estimates that the 2006 impact of adopting SFAS No. 123(R) will be approximately $1.0 million to $1.5 million before income taxes, which approximates the annual 2005, 2004 and 2003 pro forma stock-based compensation expense for stock options as included in the table above. The actual cost will differ from this range due to changes in assumptions. This estimated range primarily reflects the impact of expensing stock options for the first time. In January 2005, the company approved the acceleration of vesting for all unvested underwater options in order to mitigate the associated future share-based compensation expense under SFAS 123(R). The pro-forma net loss and pro-forma net loss per share for the year ended December 31, 2005 includes the $3.8 million impact of the acceleration of the underwater options. There was no income statement impact related to the acceleration of options for the year ended December 31, 2005. See discussion on acceleration of options in footnote 10. The increase in stock compensation expense in the pro-forma results of operations is due to the acceleration of options and higher restricted stock amortization, offsetting lower stock compensation expense related to stock options. The company calculated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model as prescribed by SFAS 123 using the following assumptions:

EMPLOYEE STOCK STOCK OPTIONS PURCHASE PLAN ------------------ ------------------ 2005 2004 2003 2005 2004 2003 ---- ---- ---- ---- ---- ---- Dividend yield......................... None None None None None None Expected volatility.................... 50% 45% 49% 37% 41% 49% Risk-free interest rate................ 3.6% 2.2% 2.1% 3.4% 1.4% 1.0% Expected life (in years)............... 2.90 3.03 2.76 0.5 0.5 0.5
Prior to 2005, the company measured volatility based on a 90-day period. For the 2005 calculation, the company calculated the volatility based on the period of January 2001 to December 2005. The company believes five years more accurately matches the expected term of the options. The stock-based compensation expense related to stock options in the pro-forma net loss amount for 2005 in the table above is based on the revised volatility. The total stock-based compensation expense of $9.0 million includes $1.2 million compensation expense related to stock options. The impact on the 2005 expense for the change in the volatility measurement was an increase of $0.1 million. In fiscal 2005, 2004 and 2003 pro forma stock compensation expense, the company recognized employee forfeitures as incurred. In 2006, the company will incorporate a forfeiture rate in the expense calculation. The company does not expect the effect of using a forfeiture rate for stock options rather than including forfeiture as incurred to materially impact the stock compensation expense. In 2006, all other assumptions will be consistent with the assumptions used for the 2005 option pricing model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility and expected option life. Because the company's employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair 48

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 value estimate the existing models may not necessarily provide a reliable single measure of the fair value of the employee stock options. Based on the Black-Scholes option-pricing model, the weighted average estimated fair value of employee stock option grants was $3.03 for 2005, $3.63 for 2004, and $2.79 for 2003. Restricted stock awards are recorded at the fair market value of the stock on the date of grant and is expensed over the vesting period. EARNINGS PER SHARE The company computes earnings per share in accordance with SFAS No. 128, "Earnings Per Share". SFAS No. 128 requires companies to compute net income per share under two different methods, basic and diluted, and present per share data for all periods in which statements of operations are presented. Basic earnings per share is computed by dividing net income/(net loss) by the weighted average number of shares of common stock outstanding, less shares subject to repurchase. Diluted earnings per share are computed by dividing net income by the weighted average number of common stock and common stock equivalents outstanding. Common stock equivalents consist of stock options using the treasury stock method. Common stock options are excluded from the computation of diluted earnings per share if their effect is anti-dilutive. The weighted average common stock option grants excluded from the calculations of diluted net loss per share were 554,699 for the year ended December 31, 2005. The following table provides a reconciliation of the numerators and denominators used in calculating basic and diluted earnings per share for the years ended December 31, 2005, 2004 and 2003, respectively (in thousands, except per share data):

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 GOODWILL AND OTHER INTANGIBLE ASSETS SFAS No. 141 requires all business combinations to be accounted for using the purchase method. SFAS No. 142 addresses the financial accounting and reporting standards for goodwill and intangible assets subsequent to their initial recognition. SFAS No. 142 requires that goodwill no longer be amortized. It also requires that goodwill and other intangible assets be tested for impairment at least annually and whenever events or circumstances occur indicating that goodwill might be impaired. The company conducted the annual impairment test of goodwill and long-lived assets as of October 31, 2005. The estimate of future undiscounted cash flows for this test was based on historical sales trends, financial projections, market analysis, capital expenditure needs, working capital needs, analyst reports, and other data pertinent to the valuation as provided by the company and obtained from public, financial, and industry sources. The company's assumptions required significant judgment and actual cash flows may differ from those forecasted today. The company believes the assumptions used for discounting future cash flows were appropriately conservative. Based on the results of the test, there was no impairment of goodwill or other intangible assets. Additionally, an acquired intangible asset should be separately recognized if the benefit of the intangible asset is obtained through contractual or other legal rights, or if the intangible asset can be sold, transferred, licensed, rented, or exchanged, regardless of the acquirer's intent to do so. Intangible assets consist principally of technology, non-compete agreements, patents, trademarks and tradenames, and customer relationships and are amortized over a period of one to eight years. RECENT ACCOUNTING PRONOUNCEMENTS In March 2005, the Securities and Exchange Commission ("SEC") issued Staff Accounting Bulletin ("SAB") No. 107, which provides guidance on the implementation of Statement of Financial Accounting Standards ("SFAS") No. 123(R), "Share-Based Payment" (see discussion below). In particular, SAB No. 107 provides key guidance related to valuation methods (including assumptions such as expected volatility and expected term), the accounting for income tax effects of share-based payment arrangements upon adoption of SFAS No. 123(R), the modification of employee share options prior to the adoption of SFAS No. 123(R), the classification of compensation expense, capitalization of compensation cost related to share-based payment arrangements, first-time adoption of SFAS No. 123(R) in an interim period, and disclosures in Management's Discussion and Analysis subsequent to the adoption of SFAS No. 123(R). SAB No. 107 became effective on March 29, 2005. The Company will apply the principles of SAB 107 in conjunction with its adoption of SFAS 123(R) in the quarter ending March 2006. In May 2005, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 154, "Accounting Changes and Error Corrections" , a replacement of APB Opinion No. 20 and FASB Statement No. 3. This statement applies to all voluntary changes in accounting principle, and requires retrospective application to prior periods' financial statements for changes in accounting principle. SFAS No. 154 will be effective for the company beginning in fiscal year 2007. The company does not believe this statement will have a material impact on the company's financial statements. In December 2004, the Financial Accounting Standards Board ("FASB") issued FAS No. 123R, "Share-Based Payment". The statement addresses the accounting for transactions in which an enterprise receives employee services in exchange for (a) equity instruments of the enterprise or (b) liabilities that are based on the fair value of the enterprises equity instruments or that may be settled by the issuance of such equity instruments. FAS No. 123R is effective no later than annual reporting periods ending after June 15, 2005. The company will adopt FAS No. 123R on a prospective basis starting in the first quarter of fiscal 2006. The company expects the adoption of FAS No. 123R to have a material effect on our reported net income per share. During January 2005 and in advance of the adoption of FAS No. 123R, the company accelerated the 50

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 vesting of "out of the money" options with a share price equal to or greater than $10.00. Under FAS 123R, the acceleration of these options will result in PCTEL not being required to recognize share-based compensation expense of approximately $3.8 million beginning in the company's quarter ending March 31, 2006 and ending in the company's quarter ending March 31, 2008. See footnote 10 in the Notes to the Financial Statements. In December 2004, the FASB issued Staff Positions in relation to FAS No. 109, "Accounting for Income Taxes". FASB issued FSP FAS 109-1, "Application of FASB Statement No. 109, Accounting for Income Taxes, to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004". As a domestic manufacturer, the company will access in 2006 whether the company is eligible for any tax deductions under this Act. FASB issued FSP FAS 109-2, "Accounting and Disclosure Guidance for the Foreign Repatriation Provision within the American Jobs Creation Act of 2004. At this time the company does not expect to repatriate the earnings of our foreign subsidiaries as dividends to take advantage of this tax credit. In November 2004, the FASB issued FAS No. 151, "An Amendment of ARB No. 43, Chapter 4". The statement amends the guidance in ARB No. 43, Chapter 4, "Inventory Pricing," to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). FAS No. 151 is effective for inventory costs incurred during fiscal years beginning after June 15, 2005. The company will adopt FAS 151 in fiscal 2006. Adoption of FAS No. 151 is not expected to have a material effect on the ongoing operations of the company. NOTE 2. ACQUISITIONS Sigma On July 4, 2005, the company purchased all of the outstanding shares of Sigma Wireless Technology Limited ("Sigma"). Sigma is based in Dublin, Ireland and develops, manufactures and distributes antenna products designed for public safety and for the UMTS cellular networks. Sigma currently employs 87 people in Ireland and the United Kingdom. The Sigma acquisition expands the company's product lines within its APG segment. With the acquisition of Sigma, the company gains entry into the growing cellular base station antenna market and also gains a geographic footprint in Europe. In exchange for all of the outstanding shares of Sigma, the company paid cash consideration of 19.4 million Euro (approximately $23.1 million), plus assumed an unfunded pension obligation of approximately 2.5 million Euro (approximately $3.0 million), and incurred approximately 1.7 million Euro (approximately $2.0 million) in transaction costs. In addition to the cash consideration at closing, the selling stockholders of Sigma may earn up to an additional 7.5 million Euro (approximately $9.1 million) in cash based on Sigma's revenue performance over the 18-month period ending December 31, 2006. The total purchase price of 23.6 million Euro (approximately $28.2 million) was allocated $8.2 million to tangible assets acquired, $7.8 million to liabilities assumed, $2.5 million to core technology, $6.4 million to customer relationships, and $0.1 million to order backlog in the accompanying consolidated balance sheets. The intangible assets have a weighted average amortization period of six years. The $15.7 million excess of the purchase price over the fair value of the net tangible and intangible assets was allocated to goodwill. The company will amortize the order backlog over one year and the other intangible assets over six years. The company evaluated the value of the assets acquired from Sigma. A third-party valuation firm was engaged to assist in the evaluation. 51

Dynamic Telecommunications, Inc. In March 2003, PCTEL, Inc., completed its asset acquisition of Dynamic Telecommunications, Inc., ("DTI") through a newly wholly owned subsidiary PCTEL Maryland, Inc. DTI is a supplier of software-defined radio technology deployed in high-speed wireless scanning receivers, multi-protocol collection and analysis systems, interference measurement systems and radio frequency command and control software solutions. In connection with the asset acquisition, PCTEL Maryland, a wholly-owned subsidiary of PCTEL, and DTI Holdings, Inc., the sole shareholder of DTI, entered into an Asset Purchase Agreement dated as of March 12, 2003 under which the wholly-owned subsidiary acquired substantially all of the assets of DTI, including intellectual property, receivables, property and equipment and other tangible and intangible assets used in DTI's business. In exchange for the acquired net assets, PCTEL paid DTI Holdings $11.0 million in cash. In addition, DTI is entitled to earn-out payments as a result of PCTEL Maryland, Inc. meeting specified financial targets in fiscal years 2003 and 2004. DTI earned approximately $1.5 million for 2003 that was recorded as additional goodwill at December 31, 2003 and paid on May 1, 2004. For the year ended December 31, 2004, DTI earned a cash payout of approximately $0.6 million, which was accrued and recorded as additional goodwill. This amount was paid in April 2005. The purchase price of $11.0 million was allocated to the assets acquired and liabilities assumed at their estimated fair values on the date of acquisition as determined by an independent valuation firm. The purchase price was allocated $2.3 million to net assets acquired, $1.1 million to acquired in-process research and development, $0.2 million to the covenant not to compete and $4.4 million to other intangible assets, net, in the accompanying consolidated balance sheets. The $3.0 million excess of the purchase price over the fair value of the net tangible and intangible assets was allocated to goodwill. In-process research and development costs were expensed and the covenant not to compete is being amortized over two years and other intangible assets over an estimated useful life of four years. The company evaluated the value of the assets acquired from Andrew. A third-party valuation firm was engaged to assist in the evaluation.. An additional payment of $0.2 million was made in July 2003 to DTI after they delivered a final balance sheet as agreed upon in the Asset Purchase Agreement. The additional payment was recorded as goodwill. 54

NOTE 3. DISPOSITION In May 2003, the company completed the sale of certain of its assets to Conexant Systems, Inc., ("Conexant"). Conexant is a supplier of semiconductor system solutions for communications applications. In connection with the transaction, the company and Conexant entered into an Asset Purchase Agreement dated as of May 8, 2003 (the "Purchase Agreement") under which Conexant acquired specified assets of the company relating to a component of the company HSP modem operations and consisting of inventory, fixed assets from the company offices in Taiwan, contracts with customers and distributors related to the soft modem products, and limited intellectual property. The company did not transfer any of its patent portfolio in connection with this transaction, and the company retained all operating contracts and intellectual property assets associated with its hardware modem and wireless products. In exchange for the assets acquired from PCTEL, Conexant paid approximately $10.75 million in cash to the company, which represents $8.25 million plus the book value of the acquired inventory and fixed assets being transferred to Conexant. Conexant assumed certain liabilities of the company. The total proceeds of $10.75 million netted a gain on sale of assets of $4.5 million. In connection with the Purchase Agreement, Conexant agreed to license the company's Segue Wi-Fi software for use with certain of its products. Conexant will pay the company an aggregate of $1 million, as consideration for this license. Concurrent with the completion of the transaction with Conexant, the company and Conexant also completed an Intellectual Property Assignment Agreement and Cross-License Agreement ("IPA"). The company provided Conexant with a non-exclusive, worldwide license to certain of the company's soft modem patents. In addition, Conexant assigned 46 U.S. patents and patent applications relating to modem and other access technologies to the company as part of the transaction. In consideration for the rights obtained by Conexant from the company under this agreement, and taking into account the value of rights obtained by the company from Conexant under this agreement, during the period beginning on July 1, 2003 and ending on September 30, 2007, Conexant agreed to pay to the company, on a quarterly basis, royalties in the amount of ten percent (10%) of the revenue received during the royalty period, up to a maximum amount of $0.5 million per quarter with respect to each calendar quarter during the royalty period, contingent upon sales by Conexant during the period. Any such future payments by Conexant to the company in connection with the IPA will be recorded as part of the gain on sale of assets and related royalties in the statement of operations. . The company amended the cross license agreement with Conexant in August 2005. The period for which the royalties are payable was extended to end on June 30, 2009. The quarterly royalty maximum was amended to be $250,000 per quarter from January 1, 2006 through December 31, 2007 and $200,000 per quarter from January 1, 2008 through June 30, 2009. 55

NOTE 6. RESTRUCTURING CHARGES 2004 Restructuring In October 2004, the company discontinued its Soft AP product line. The amount charged to restructuring for severance costs in California and Taiwan as well as costs associated with the closure of the Taiwan branch office was $0.1 million. The 2004 restructuring costs were paid in full by the end of fiscal 2005. 2003 Restructuring In May 2003, the company completed the sale of certain of its assets to Conexant relating to a component of PCTEL's HSP modem product line. As a result of the disposition, 29 employees were transferred to Conexant. An additional 26 employees, both foreign and domestic, were terminated along with the related facilities closures. The total restructuring aggregated $3.3 million consisting of severance and employment related costs of $1.8 million and costs related to closure of excess facilities as a result of the reduction in force of $1.5 million. As a result of lower than estimated facility shut down costs, the company reversed $0.1 million of the restructuring reserve in both 2004 and 2005. The 2003 restructuring costs were paid in full by the end of fiscal 2005. The following analysis sets forth the rollforward of this charge:

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The net deferred tax accounts consist of the following (in thousands):

DECEMBER 31, ------------------- 2005 2004 -------- -------- Accruals and reserves....................................... $ 1,048 $ 2,353 Net operating loss carryforwards............................ 2,140 344 State tax credits........................................... 3,840 2,983 Restricted stock............................................ 976 654 Depreciation and amortization............................... 5,810 5,531 -------- -------- 13,814 11,865 Valuation allowance.........................................

(805) (417) -------- -------- Net deferred tax liability................................ $ (805) $ (417) ======== ========
At December 31, 2005, the company had a full valuation allowance against the deferred tax assets due to the uncertainty surrounding the realization of such assets. On a periodic basis, management evaluates the recoverability of deferred tax assets and the need for a valuation allowance. At such time as it is determined that it is more likely than not that the deferred tax assets are realizable, the valuation allowance will be reduced. The 2004 and 2003 effective tax rate and 2004 deferred tax asset and related valuation allowance disclosures include an adjustment to correct an error related to the treatment of deferred taxes on restricted stock discovered in 2005. As a result, the Company increased the deferred tax asset and valuation allowance as of December 31, 2004 by $654,000. The Company determined that the impact of this adjustment was immaterial for all current and prior periods. These adjustments had no impact on the Company's results of operations or financial position for any period. During the fourth quarter 2005, the company changed its estimate regarding the character in taxation of certain leasing income received in 2004. As a result, the company reversed the tax expense it booked in 2004 to reflect the change in estimate regarding its filing position. The company believes that approximately $0.4 million of undistributed earnings of non-domestic subsidiaries were reinvested indefinitely, and no federal income tax should be provided under the plan of investment. The American Jobs Creation Act of 2004 ("the Act") was passed into law on October 22, 2004 and introduced a special one-time dividend received deduction under certain circumstances on the repatriation of certain foreign earnings to a United States of America taxpayer. At this time the company does not expect to repatriate the earnings of our foreign subsidiaries as dividends to take advantage of this tax credit. At December 31, 2005, the company had the following net operating losses for tax purposes:
2005 ------- Federal..................................................... $ 1,432 State....................................................... 4,895 Foreign..................................................... $12,805

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 The Federal net operating loss carryforwards of $1.4 million begin to expire in 2024; state net operating loss carryforwards of $4.9 million begin to expire in 2014; and foreign net operating loss carryforwards begin to expire in 2010. NOTE 8. CONTINGENCIES The company has from time to time in the past received correspondence from third parties, and may receive communications from additional third parties in the future, asserting that the products infringe on their intellectual property rights, that the patents are unenforceable or that the company has inappropriately licensed the intellectual property to third parties. The company expects these claims to increase as our intellectual property portfolio becomes larger. These claims could affect the company's relationships with existing customers and may prevent potential future customers from purchasing the company's products or licensing the technology. Intellectual property claims against the company, and any resulting lawsuit, may result in incurring significant expenses and could subject the company to significant liability for damages and invalidate the company's proprietary rights. These lawsuits, regardless of their success, would likely be time-consuming and expensive to resolve and could divert management's time and attention. In addition, any claims of this kind, whether they are with or without merit, could cause product shipment delays or require the company to enter into royalty or licensing agreements. In the event that PCTEL does not prevail in litigation, the company could be prevented from selling the company's products or be required to enter into royalty or licensing agreements on terms, which may not be acceptable to the company. PCTEL could also be prevented from selling the company's products or be required to pay substantial monetary damages. Should PCTEL cross license the intellectual property in order to obtain licenses, the company may no longer be able to offer a unique product. To date, PCTEL has not obtained any licenses from 3Com and the other companies from whom the company has received communication. Ronald H. Fraser v. PC-Tel, Inc., Wells Fargo Shareowner Services, Wells Fargo Bank Minnesota, N.A. In March 2002, plaintiff Ronald H. Fraser ("Fraser") filed a complaint in the California Superior Court for breach of contract and declaratory relief against the company, and for breach of contract, conversion, negligence and declaratory relief against the company's transfer agent, Wells Fargo Bank Minnesota, N.A. The complaint seeks compensatory damages allegedly suffered by Fraser as a result of the sale of certain stock by Fraser during a secondary offering in April, 2000. At a mandatory settlement conference held in September 2004, Fraser stipulated to judgment in favor of the company. In November 2004 Fraser appealed the judgment entered against him. Fraser filed his opening brief in October 2005. The appellant's reply brief is due in March 2006. While the company believes that this appeal is without merit and intends to defend the appeal vigorously, the company cannot predict or determine the outcome or resolution of this proceeding or the potential range of loss if any. Litigation with U.S. Robotics In May 2003, the company filed in the U.S. District Court for the Northern District of California a patent infringement lawsuit against U.S. Robotics Corporation claiming that U.S. Robotics has infringed one of the company's patents. U.S. Robotics counterclaimed asking for a declaratory judgment that the claims of the patent are invalid and not infringed. In December 2005, the parties entered into a settlement agreement which was favorable to the company, and the Court granted the parties' stipulated request that all claims and counterclaims in the action be dismissed with prejudice. Under the agreement, U.S. Robotics will take a license to specific PCTEL modem patents. PCTEL receives a lump-sum royalty payment, a cross-license to U.S. Robotics patents and patent applications, and royalties in the future that can be satisfied with cash payments or product purchases. 61

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 Litigation with Agere and Lucent In May 2003, the company filed in the U.S. District Court for the Northern District of California a patent infringement lawsuit against Agere Systems and Lucent Technologies claiming that Agere has infringed four of the company's patents and that Lucent has infringed three of the company's patents. Agere counterclaimed asking for a declaratory judgment that the claims of the four patents are invalid, unenforceable and not infringed by Agere. Because of a then-pending reexamination proceeding for PCTEL's U.S. Patent No. 5,787,305 (the '305 patent), the claims against Agere and Lucent relating to the '305 patent were stayed by stipulation of the parties. Claims construction discovery under the Patent Local Rules was taken with respect to the three patents as to which the litigation was not stayed, and the claims construction issues relating to those patents have been briefed to the Court. A hearing on the construction of the claims of those patents was held in May 2005, and the court issued its claim construction ruling in September 2005. The stay regarding the '305 patent was lifted by stipulation of the parties after the company received the Reexamination Certified from the U.S. Patent Office. Claims construction discovery was taken with respect to the '305 patent. A hearing on the construction of the claims of the '305 patent was held in January 2006 and the court has taken the matter under submission. No trial date has been set. Although the company believes that it has meritorious claims and defenses, the company cannot predict or determine the outcome or resolution of this proceeding or the potential range of loss if any.

Executive Plan In 2001, in connection with the hiring and appointment of two executive officers of PCTEL, the company granted an aggregate amount of 300,000 options at $8.00 per share outside of any stock option plan, pursuant to individual stock option agreements. As of December 31, 2005, 86,667 options are outstanding. 1998 Director Option Plan ("Directors Plan") The Directors Plan became effective following the company's IPO in October 1999. In June 2003 the shareholders approved amendments to the plan, which added 200,000 shares for a plan total of 400,000 shares and increased the annual options granted to the Board of Directors from 7,500 to 10,000 shares. Therefore, the company reserved a total of 400,000 shares of common stock that the company can issue under the company's Directors Plan. Under our 1998 Directors Plan, any new non-employee director elected to the Board of Directors automatically receives a grant of 15,000 shares of common stock. The 15,000 share options will vest one-third as of each anniversary of its date of grant until the option is fully vested, provided that the optionee continues to serve as a director on such dates. After the initial 15,000 share options are granted to the non-employee director, he or she shall automatically be granted an option to purchase 10,000 shares each year on 64

PCTEL, INC.

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 As of December 31, 2004, there were 1,555,523 options exercisable at a weighted average price of $9.77. As of December 31, 2003 there were 1,159,232 options exercisable at a weighted average exercise price of $11.98 and as of December 31, 2002, there were 2,080,916, options exercisable at a weighted average exercise price of $13.40. Acceleration of Underwater Options On January 28, 2005, the Compensation Committee of the Board of Directors approved the acceleration of vesting of all unvested options to purchase shares of common stock of PCTEL that are held by current employees, including executive officers, and which have an exercise price per share equal to or greater than $10.00. Options to purchase 1,606,805 shares of common stock were accelerated under this approval. The company accelerated these options in order to mitigate the associated future share-based compensation expense under SFAS 123(R). The acceleration of these options will result in PCTEL not being required to recognize share-based compensation expense of approximately $3.8 million beginning in the company's quarter ending March 31, 2006 and through the company's quarter ending March 31, 2008. The pro-forma net loss and pro-forma net loss per share for the year ended December 31, 2005 in footnote 1 includes the $3.8 million impact of the acceleration of the underwater options. There was no income statement impact related to the acceleration of options for the year ended December 31, 2005. Employee Stock Purchase Plan ("Purchase Plan") In May 1998, the company reserved a total of 800,000 shares of common stock for future issuance under the company's Purchase Plan, plus annual increases equal to the lesser of (i) 350,000 shares (ii) 2% of the outstanding shares on such date or (iii) a lesser amount determined by the Board of Directors. The Purchase Plan will enable eligible employees to purchase common stock at the lower of 85% of the fair market value of the common stock on the first or last day of each offering period. Each offering period is six months. The Purchase Plan will terminate in 2008. During 2005, 69,636 shares were issued under the Purchase Plan. As of December 31, 2005, the company had 1,781,287 shares remaining that can be issued under the Purchase Plan. Deferred Stock Compensation The company grants restricted shares as employee incentives as permitted under the company's 1997 Stock Plan. In connection with the grant of restricted stock to employees, the company records deferred stock compensation representing the fair value of the common stock on the date the restricted stock is granted. Such amount is presented as a reduction of stockholders' equity and is amortized ratably over the vesting period of the applicable shares. For the year ended December 31, 2005, the company issued restricted stock for $5.6 million and recorded terminations of $0.7 million. The number of restricted shares issued was 720,436 in 2005. For the year ended December 31, 2004, the company issued restricted stock for $3.4 million, recorded terminations of $0.1 million. The number of shares issued in 2004 was 292,778. The number of shares issued increased from prior years due to the decision by the company to emphasize the use of restricted shares as equity incentives in 2005. The following table summarizes restricted stock activity for the years ended December 31:

INDUSTRY SEGMENT, CUSTOMER AND GEOGRAPHIC INFORMATION In 2003 the company operated as a single segment. In January 2004 PCTEL began operating in five distinct segments. They are Mobility Solutions (previously software), RF Solutions (previously test), Antenna Product (previously antenna), Modems and the Licensing segment. In May 2003, the company sold its modem product line to Conexant. Intercompany sales and profits from Antenna Products to RF Solutions are eliminated. APG (core) and Sigma are separate operating segments. However, given their similar long-term economic characteristics, services provided, processes, types of customers, methods of delivery, regulatory requirements, and meeting certain quantitative thresholds, the company has concluded these operating segments should be combined into a ingle reporting segment -- APG PCTEL's chief operating decision maker (CEO) uses only the below measures in deciding how to allocate resources and assess performance among the segments. 68

NOTE 15. BENEFIT PLANS 401(k) Plan The 401(k) plan covers all of the employees beginning the first of the month following the month of their employment. Under this plan, employees may elect to contribute up to 15% of their current compensation to the 401(k) plan up to the statutorily prescribed annual limit. The company may make discretionary contributions to the 401(k). The company made $0.5 million in employer contributions to the 401(k) plan for each of the years ended December 31, 2005, 2004 and 2003. Post-retirement health insurance Effective July 2003, the company started a plan to cover post-retirement health insurance for Martin H. Singer, Chairman of the Board and Chief Executive Officer. Based on an actuarial valuation prepared by RSM McGladrey in accordance with FAS 106, the company's accumulated post retirement benefit obligation for this plan was $141,000 at December 31, 2005. See subsequent footnote 17 related to the amended employment agreement with Martin H. Singer. Personal Retirement Savings Account The Personal Retirement Savings Account (PRSA) covers all current Sigma employees. Under this plan, there is no limit for employees contributions of their current compensation to the PRSA plan. The company may make discretionary contributions to this plan. The company made contributions of $7,000 for the six months ended December 31, 2005. Pension Plan Certain Sigma employees participate in a defined benefit pension scheme. Prior to the acquisition in July 2005 and through December 2005, these employees participated in the Sigma Communications Group Retirement and Death Benefit Plan ("old plan"). Effective December 2003, this plan was frozen to new 70

PCTEL, INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) FOR THE YEAR ENDED: DECEMBER 31, 2005 employees. In January 2006, the Sigma participants from the old plan were transferred to a new retirement and death benefit plan ("PCTEL Europe Pension Plan" or "new plan"). The PCTEL Europe Pension Plan has attributes identical to the old plan. All employees retained their service period under the old plan. At December 31, 2005, there were 56 participants in the new plan. The assets will be transferred to the new plan during the quarter ending March 2006. The assets will be invested in the Pension Consensus Fund managed by Irish Life Investment Managers Limited. The amounts included as transfers in the information below are estimates based on actuarial assumptions. Once the assets are transferred, the trustees of the new plan will approve the asset allocations and other financial assumptions. The current financial assumptions are based on the old plan. The discount rate is the rate of interest used to discount benefit obligations and has been determined by reference to market yields at the balance sheet date on high quality corporate bonds. The currency and term of the corporate bonds is consistent with the currency and estimated term of the post-employment benefit obligations. At the measurement date of December 31, 2005 the iBoxx index of euro-denominated AA-rated corporate bonds yielded 4.01% per annum, with individual stocks yielding higher amounts. Taking into account the profile and duration of the plan's liabilities, a discount rate of 4.25% has been adopted. The investment strategy pursued by the Pension Consensus Fund is to broadly maintain a diversified portfolio of 60%-90% in real assets such as equities and property, with the balance in monetary assets such as fixed interest and cash. The expected return on plan assets of 6.5% was based on the current asset allocation and the long-term expected returns for each asset class. The plan's liabilities under FAS 87 are highly dependent on the yield on corporate bonds. The assets are invested primarily in equities. The mismatch between the notional assets needed to back the liabilities and the assets actually held is likely to result in a significant degree of volatility of the funded status from year to year. For the six months ended December 31, 2005, the company recognized consolidated pension expense of $129,000 and contributed approximately $62,000 to the new plan. The company's funding policy is to contribute cash to the pension plan in order to at least meet the minimum contribution requirements. The company will be required to make payments for the under funded amount. Once the new plan is set up, the company will determine the timing of the payments for the under funded balance. The estimated payments to the new plan in 2006 are approximately $0.5 million. At December 31, 2005, the defined benefit obligation was $5.8 million, the fair value of the plan assets was $2.6 million, and the company's net pension liability was $3.1 million. From the acquisition date, the pension liability increased $62,000. Our expenses for pension benefits was as follows for the six months ended December 31, 2005 (in thousands):

During the fourth quarter of 2005, the company changed its estimate regarding the character in taxation of certain leasing income received in 2004 for one of its Israeli subsidiaries. See footnote 7 related to income taxes. NOTE 17. SUBSEQUENT EVENT On January 6, 2006, upon authorization of the Compensation Committee of the Board of Directors, the company and Martin H. Singer, entered into an amended and restated employment agreement which eliminated the post-retirement healthcare benefits for Mr. Singer and his family that were previously included in his original employment agreement. Mr. Singer requested the elimination of these benefits for reasons related to future corporate expense, the company's commitment to defined contribution plans rather than defined benefit plans, and parity of benefits with other executives of the company. The company will reverse the liability of $141,000 in the quarter ending March 31, 2006. 74

ITEM 9: CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE. None. ITEM 9A: CONTROLS AND PROCEDURES (a) EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES Under the supervision and with the participation of PCTEL management, including the company's Chairman and Chief Executive Officer and its Chief Financial Officer, our management evaluated the effectiveness of the company's disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended, as of December 31, 2005. Based on that evaluation, the Company's Chairman and Chief Executive Officer and its Chief Financial Officer concluded that the company's disclosure controls and procedures were not effective at the reasonable level of assurance as of December 31, 2005 because of the material weakness discussed below. (b) MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING Management of PCTEL is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. PCTEL's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. Internal control over financial reporting includes those policies and procedures that: - pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of PCTEL; - provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles in the United States of America, and that receipts and expenditures of PCTEL are being made only in accordance with authorizations of management and directors of PCTEL; and - provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of PCTEL's assets that could have a material effect on the financial statements. The management of PCTEL has assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2005. In making its assessment of internal control over financial reporting, management used the criteria described in "Internal Control -- Integrated Framework" issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Management has excluded Sigma Wireless Technologies ("Sigma") from its assessment of the effectiveness of internal control over financial reporting as of December 31, 2005 because Sigma was acquired by the Company through a purchase business combination in July 2005. Sigma is a wholly owned subsidiary of the Company that represents 21% of consolidated total assets and 5% of consolidated revenues, respectively, as of and for the year ended December 31, 2005. A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. As of December 31, 2005, the Company did not maintain effective controls over the review, completeness and accuracy of its provision for income taxes and the related financial statement presentation and disclosure of income tax matters. This control deficiency resulted in audit adjustments to the 2005 annual consolidated financial statements with respect to income tax disclosures and the 2005 second quarter consolidated financial statements with respect to the provision for income taxes. In addition, this control deficiency could result in a misstatement of the income tax provision and income tax related financial statement disclosures that would result in a material misstatement of the annual or interim financial statements that would not be prevented or 75

detected. Accordingly, management has concluded that this control deficiency constitutes a material weakness. Because of this material weakness, management has concluded that the Company did not maintain effective internal control over financial reporting as of December 31, 2005, based on the criteria in "Internal Control-Integrated Framework" issued by the COSO. Management's assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 2005 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein. (c) CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING As disclosed in the Company's 2004 Annual Report on Form-10K and in its Quarterly Reports on Form 10-Q for each of the first three quarters of 2005, the Company previously reported a material weakness in internal control over the accounting for income taxes, including the determination of income taxes payable, deferred income tax assets and liabilities and the related income tax provision. Specifically, the Company did not have effective controls over determining net operating loss carry backs, applicable state tax rates applied, and the tax effect of stock option exercises. In addition, the Company did not have effective controls to monitor the difference between the income tax basis and the financial reporting basis of assets and liabilities and reconcile the difference to deferred income tax assets and liabilities. During the year ended December 31, 2005, the Company made significant progress in executing the remediation plans that were established to address the material weakness in its internal control surrounding the accounting for income taxes. This resulted in certain improvements in the Company's internal control over financial reporting. With the help of external advisors (other than the company's independent registered public accounting firm), the following remedial actions have been undertaken: - Engaged an outside tax consultant to prepare the tax provision, provide tax expertise and expertise in the application of Statement of Financial Accounting Standards No. 109 "Accounting for Income Taxes". - Implemented an internal training program to enhance the capabilities of its internal tax personnel. - Acquired software to automate and better control the tax provision preparation process. - Improved its system of internal controls over the review of the consolidated income tax provision. Specifically, the Company's changes in controls over income taxes were successful in the remediation of the deficiencies related to the determination of income tax payable and deferred income tax assets and liabilities. As demonstrated by the above, the Company has made significant progress in its efforts to remediate this material weakness during 2005. This is further supported by the Company's overall positive results from its 2005 internal control compliance testing required by Section 404 of the Sarbanes-Oxley Act of 2002, which was carried out by the Company in the third and fourth quarters of 2005. In making its determination as to the status of the remediation of this material weakness, the Company has considered all of the factors outlined above and has concluded that the internal controls surrounding the accounting for income taxes are effectively designed, however, as a result of the audit adjustments, the Company has not demonstrated operating effectiveness with respect to controls over the completeness and accuracy of its income tax provision and the presentation and disclosures related to income taxes. Accordingly, as discussed in "Management's Report on Internal Control Over Financial Reporting" above, the Company reported this as a material weakness as of December 31, 2005. In order to remediate this deficiency in internal controls, the Company will continue its training and education efforts in this area so that operating effectiveness can be demonstrated over a period of time that is sufficient to support the conclusion that the material weakness has been remediated. In addition, to further enhance the controls surrounding the accounting for income taxes, the Company will continue its efforts with 76

respect to 1) its oversight over the quarterly and annual preparation of its tax provision and related disclosures by its outside tax consultant, and 2) the need to consider additional resources to help execute its internal controls over the accounting for income taxes. Except as otherwise discussed above, there have been no changes in the Company's internal control over financial reporting during the most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
