GENERAL DEVELOPMENT OF THE BUSINESS

General

We provide leading edge wireless wide-area modem solutions for mobile computing over cellular networks. We develop and market a broad range of products that include wireless modems for mobile computers, embedded modules for original equipment manufacturers, or OEMs, and rugged vehicle-mounted modems. Our products permit users to access wireless data and voice communications networks using laptop computers, handheld mobile computing devices, or vehicle-based systems.

Wireless data communications is an expanding market positioned at the convergence of wireless communications, mobile computing and the Internet, each of which we believe represents a growing market. Our products are based on open standards, including the Internet protocol, and operate on the networks of major wireless operators around the world.

Our products are primarily used by businesses and government organizations to enable their employees to access a wide range of applications, including the Internet, e-mail, corporate intranet, remote databases and computer aided dispatch. We sell our products worldwide, with emphasis on the North American, European and Asia-Pacific regions, through indirect channels, including wireless operators, resellers and OEMs.

During the latter part of 2003 and throughout 2004, we experienced stronger than expected demand for our products, primarily as a result of our strong market position in CDMA EV-DO Release 0 PC cards and our CDMA 1X embedded module sales to palmOne. During this period, customer concentration increased in our revenue base. Following our considerable revenue and earnings growth in 2004, we experienced a significant reduction in our business in 2005 relative to 2004 as a result of:

• The reduction in our embedded module business volumes as a result of the completion of CDMA 1X module shipments to palmOne for its Treo 600 Smartphone at the end of 2004;

• Reported channel inventory at some of our channel partners that was already sufficient to meet near-term customer demand during the first quarter of 2005; and

• The near-term impact of increased competition in CDMA EV-DO and EDGE PC cards, including a loss of market share at Verizon Wireless.

In order to address this change in our business, we undertook a restructuring of our operations in June 2005, which included exiting our Voq professional phone initiative. The result of this restructuring was a reduction in our cost structure and a greater focus on our core PC card and embedded modules business, where we already have well-established market positions and believe there are significant growth opportunities.

Since the mid-year restructuring, we have focused on core PC Card and embedded module opportunities for existing products, as well as new product development and business development in these areas. This focus has allowed us to return to sequential quarterly revenue growth during the second half of fiscal 2005, realizing 25% and 37% sequential growth in the third and fourth quarters respectively. Following the restructuring, we were also able to reduce our net loss and improve cash flow during the second half of 2005.

During 2006, we expect to continue to invest in our research and development efforts to ensure that we are well-positioned with new products that will take advantage of market opportunities associated with the deployment of 3G networks. See “Narrative Description of Business - Our Products” for discussion of specific product development initiatives.

Industry Background and Future Trends

Wireless Data Growth

We provide a broad range of products including wireless modems for mobile computers and embedded modules for laptop OEM wireless applications. We believe that our growth potential is tied, in part, to the projected growth of the laptop PC market and to the evolution of wireless networks. In a 2005 report, research firm Gartner forecasted worldwide shipments of new laptop PCs would increase from approximately 62 million units in 2005 to 123 million units in 2009. Additionally, in a 2005 report, ABI Research forecasted that worldwide shipments of wireless modems (PC cards) for mobile computers

would increase from approximately 3.0 million units in 2005 to 9.7 million units in 2009. In-Stat/MDR forecasted that worldwide shipments of embedded modules for OEMs would increase from approximately 0.5 million units in 2005 to 7.3 million units in 2009. Cellular network technologies such as Enhanced Data over GPRS Evolution (EDGE), CDMA 1x EV-DO, Universal Mobile Telecommunications System (UMTS), and High Speed Downlink Packet Access (HSDPA) upgrades, are expected to support much of this growth.

To date, demand for wireless data has come primarily from corporations, public organizations and individuals seeking to improve customer service and productivity. Increased coverage and speeds, significant technological improvements to wireless data networks, devices and software, and price reductions for data communications services have also contributed to growth in the wireless data communications industry. The ability to meet the demand for anytime, anyplace communications is made possible by the convergence of trends in mobile computing, the growth of the Internet, and wireless communications. Gartner forecasts that by 2007, 65% of Fortune 2000 companies will support wireless wide-area wireless data access.

Mobile Computing. Mobile PCs are now mainstream. Many business professionals utilize laptops as their primary computing device giving them the mobility required to work anywhere. Smaller handheld computers or PDAs continue to be popular, as are newer mobile phones that offer more advanced capabilities, such as access to personal information, Internet and e-mail. Mobile PCs and handheld devices continue to be the leading devices that are accessing wireless data.

The Internet. The Internet has become an indispensable tool for many business professionals, and the volume of Internet traffic has grown rapidly as new applications and e-commerce have become widely adopted. Wireline telecommunications carriers continue to make significant investments in Internet protocol-based networks to handle the expected growth in the volume of data traffic.

Wireless Communications. While wireline communications networks were historically dominated by voice traffic, data now comprises more than half of the traffic on these networks. A similar evolution is now occurring on wireless networks as wireless service providers address the growing demand for data communications with additional technical and commercial offerings.

Existing and Emerging Cellular and PCS Technology Standards

Data communications over cellular networks is currently supported by various digital technologies, such as CDMA 1X, CDMA 1x EV-DO, Global System for Mobile (GSM), Generalized Packet Radio Service (GPRS), EDGE, UMTS and HSDPA.

CDMA is a digital technology that significantly improves the capacity and quality of both voice and data communications and supports a broader range of applications, including voice, wireless Internet and multimedia. Initially, second generation CDMA offered increased data rate capabilities of 14.4 kbps. In 2001, North American CDMA carriers, including Sprint PCS and Verizon Wireless, began deploying a 2.5G CDMA solution called CDMA 1X. Other CDMA carriers undertook similar efforts in Asia, Latin America and the Middle East. CDMA 1X supports faster wireless data transfers, typically ranging from 40 to 60 kbps, with a top nominal speed as currently deployed of 153 kbps. In 2004, deployments or expansions of EV-DO Release 0 service, the next generation (3G) CDMA technology were underway with Verizon Wireless and other carriers in North America and Asia Pacific. Sprint also started rolling out the same technology in 2005. EV-DO supports wireless data speeds, typically ranging from 400 to 700 kbps, an experience similar to wired broadband connections. We expect that future deployment of CDMA EV-DO Rev A commercial service, the next generation of EV-DO, will further increase awareness and expand the market for wireless data products and services.

Leading GSM carriers in North America, Europe and Asia also began shifting from first generation technology to 2G GPRS in 2001. Like 2G CDMA, GPRS improves the capacity and quality of data communications and supports a broader range of applications including wireless Internet and multimedia. GPRS offers data speed capabilities ranging from 20 to 40 kbps with a top nominal speed of 56kbps.

Third generation, or 3G, systems have been developed and launched to replace and/or complement second generation and 2.5G digital cellular systems. In 2003, AT&T Wireless and Cingular began rolling out their EDGE networks in the U.S. EDGE offers significant increases in data rates ranging from 100 to 130 kbps, with burst speeds up to 200 kbps. In 2004, UMTS rolled out, especially in Europe, allowing GSM operators to offer average data speeds of 220-320 kbps to their customers.

In late 2005, the first networks to upgrade to High Speed Downlink Packet Access (HSDPA), were Cingular Wireless in North America and Manx Telecom in the United Kingdom (an O2 subsidiary) demonstrating speeds between 500-700kbps with maximum speeds up to 1.8Mbps. Cingular has launched HSDPA into 18 metropolitan markets as of early 2006 with the intention to expand in the U.S. throughout 2006.

We have established a strong market position in EV-DO Release 0 PC cards and Mini Cards over the past 36 months. We intend to enhance our position by accelerating the introduction of EV-DO Release A devices. We expect to launch our EV-DO Release A PC cards and Mini Cards in the second half of 2006. In addition, we

expect to launch a CDMA 1X EV-DO Release A version of our MP product in the second half of 2006.

Product Development

We have built a reputation in the wireless data industry for creating state-of-the-art, high-quality products within aggressive timeframes. Our development team of approximately 141 staff, located in Richmond, BC and in Carlsbad, CA, are skilled in the areas of radio frequency, hardware, embedded software, windows software and mechanical design. Combined, this team has several hundred person years of experience in the design of small form factor wireless data and voice devices. Our product development team combines leaders with extensive experience in their fields, with younger graduates from leading universities.

We take a “core team” approach to product development. Our goal is develop a “whole” product and to ensure products are managed closely throughout their entire life cycle. As part of this approach, individuals from our product development group form product-specific teams with employees from other functional areas, including product management, operations, technical support and quality. These teams work closely to bring new products through the development phase, while balancing the market requirements of performance, time to market and product cost. Concepts and prototypes are validated by working with lead customers, channel partners and industry consultants.

Products that result from this process are designed and tested to cellular industry standards and introduced to our high-volume contract manufacturing partners for production and delivery to our customers. Included in the development effort is the certification of our products with industry and regulatory standards bodies.

A group of senior engineers develops and monitors our development standards. These standards are applied across all development projects to ensure uniformity. For example, we have adopted a core -wireless engine design approach to leverage development efforts across multiple different products. This is also intended to help our customers to utilize our different products with moderate additional integration effort on their part.

Our product development staff stays current in technology by participating in industry groups such as the Personal Computer Communications Association (PCCA), the Cellular Telecommunications Industry Association (CTIA), the Mobile Advisory Council (MAC), the USB Forum, the PCI Special Interest Group (PCI-SIG), the European Telecommunications Standards Institute (ETSI), the PCS Type Certification Review Board (PTCRB), the Third Generation Partnership Project (3GPP), the Third Generation Partnership Project 2 (3GPP2) and the International Wireless Packaging Consortium, and through ongoing technical education. We maintain close relationships with local universities by hiring co-op students, giving lectures, supporting visiting professorships and participating in regular informal meetings with faculty members.

Distribution

Our products are used by a variety of end-users, ranging from sales people and mobile executives, to police officers and utility workers. We have built a distribution channel that responds to the unique purchasing and usage requirements of our customer base. Historically, a substantial majority of our sales have come from North American markets. As our wireless technology platforms have diversified, we have built sales and distribution teams to focus on developing our business outside of North America. Currently, we have dedicated sales and distribution teams for the European, Asia-Pacific and North

American regions. Our approach to distribution takes advantage of our existing relationships with wireless operators, resellers and OEMs in order to maximize the productivity of our sales team.

Wireless Operators

Wireless operators play two key roles in our distribution strategy. First, wireless operators are often resellers for us, purchasing our products and then reselling them to end-user customers. Second, the wireless operator sales team often works with our sales team to jointly sell wireless solutions and our equipment to the end-user customers. The wireless operator channel provides us with extended customer reach, while the operators are able to leverage our wireless data expertise to help sell their products and services. We have invested a great deal of time and resources in cultivating our relationships with wireless operators and view these relationships as a critical success factor.

Resellers

Resellers purchase our products either directly from us or from a distributor and resell them to end-user customers. In order to support resellers who prefer to purchase through a distributor, we have selectively formed distribution relationships. Distributors ensure that our products are available to a large number of resellers that buy products.

Resellers generally combine our products with other elements of an overall solution, such as computer hardware, application software and bundled communication services and deliver a complete solution to the end-user customer. Resellers include computer resellers, wide-area network resellers, application developers and system integrators.

Original Equipment Manufacturers

Original equipment manufacturers represent companies that integrate our modem technology into devices they manufacture and sell to end-user customers through their own direct sales force and indirect distribution channels. Our modems have been integrated into a range of devices, such as industrial handheld computers, PDAs, Smartphones and laptop computers.

Professional Services

We also offer professional engineering services to OEM customers, leveraging our expertise in wireless design and integration to provide built-in wireless connectivity for laptop computers and other mobile computing devices.

Customer Support

We provide customers, wireless operators and other channel partners with product and technical support in several languages using telephone, e-mail and our Web site. Online resources include product documentation, technical specifications, frequently asked questions, application notes, troubleshooting notes, troubleshooting tools, and software downloads.

Marketing

Our marketing team is responsible for providing product management, strategic marketing and marketing communications for our products on an increasingly global basis. Members of the product management team play an active role in our core team approach to developing and managing individual products through their entire product life cycle. Emphasis is placed on understanding customer needs,

developing the business case, determining competitive positioning and pricing, and ensuring product completeness, which includes documentation, promotional material and marketing programs.

Strategic Marketing/Marketing Communications

We communicate our corporate and product positioning to channels and customers in our global markets in several ways, including:

• Actively seeking editorial coverage and placing advertisements in industry, business and trade publications;

• Actively participating in industry associations;

• By meeting with opinion leaders and industry analysts; and

• Participating in targeted conferences and trade shows.

We work with our channel partners to develop programs to encourage end-user customer adoption. Through marketing strategies including market analysis, branding, design, packaging and promotions, we execute and launch products into the marketplace to complement customer launch timelines.

Manufacturing

We outsource most of our manufacturing services, including parts procurement, kitting, assembly and repair. We believe that outsourcing allows us to:

• Focus on our core competencies, including research and development, sales and marketing;

• Participate in contract manufacturer economies of scale;

• Access high quality, lower cost manufacturing resources;

• Achieve rapid production scalability; and

• Reduce equipment capital costs and equipment obsolescence risk.

In addition, we perform certain manufacturing related functions in-house, including manufacturing engineering, and development of manufacturing test procedures and fixtures.

Our products are currently manufactured by Flextronics and Creation Technologies. We use Flextronics as our primary contract manufacturer and logistics partner to provide an end-to-end supply chain solution. This includes design support, procurement, low cost manufacturing and repair in China and global fulfillment services from Memphis, Tennessee. By using its fully integrated supply chain services, we expect to optimize product costs, improve alignment with our increasingly international customer base and achieve increased operating efficiencies and scalability. We expect that Creation Technologies in Canada will continue to assemble our lower unit volume products.

Employees

As of December 31, 2005 we had a total of 224 full time employees, 131 of whom are at our head office in Richmond, B.C., with the balance being located across the United States, Canada, Europe and Asia. Of the 224 employees, 123 are involved in product development, 32 are involved in manufacturing, 24 are sales and support personnel, 16 are marketing personnel, and 29 are in finance and administration. Employees have access to corporate-funded ongoing training and professional development opportunities, both on-the-job and through outside educational programs. Cash compensation, our employee stock

option plan, our employee stock purchase plan and our retirement plan contribution program are complemented by internal recognition programs and career advancement opportunities. We believe our relationships with our employees are positive.

We have entered into non-disclosure agreements and confidentiality agreements with key management personnel and with substantially all of our employees.

Competition

Wireless data technologies are converging toward standardizing on a few key cellular technologies. Cellular handsets are becoming ‘smart’ with increased data functionalities, PDAs are becoming wireless through the integration of embedded wireless capability, and laptop OEMs are beginning to embed wireless wide area network capability into their laptops. With the advent of new cellular technologies such as CDMA 1xEV-DO, EDGE, UMTS and HSDPA, new competitors are emerging.

CDMA: Sierra Wireless is well established in the CDMA PC Cards, embedded modules and mobile in-vehicle solutions markets. CDMA competition, both announced and actual, includes Novatel Wireless, Curitel, Kyocera Wireless, Sony Ericsson, ZTE and Wavecom. Sierra Wireless maintains its market leadership position in mobile in-vehicle solutions against competitors such as AirLink and Bluetree Wireless.

GSM: Sierra Wireless is well established in the GPRS/EDGE/UMTS/HSDPA PC cards embedded modules and mobile in-vehicle solutions markets. In these technologies, we face competition, both announced and actual, from Option NV, Novatel Wireless, Huawei, Siemens, Sony Ericsson and Blue Tree Wireless.

We believe that by focusing on wireless operators, OEMS, business and government customers and by providing products that are superior in quality, functionality, time to market and value, together with excellent customer service and superior distribution partner relationships and programs, we will be successful in our target markets.

Intellectual Property

We protect our intellectual property through a combination of patent protection, copyright, trademarks, trade secrets, licenses, non-disclosure agreements and contractual provisions. We enter into a non-disclosure and confidentiality agreement with each of our employees, consultants and third parties that have access to our proprietary technology. Pursuant to assignment of inventions agreements, all of our employees and consultants assign all intellectual property rights in the inventions created during such person’s employment or contract with Sierra Wireless to Sierra Wireless.

We currently hold 45 United States patents and 65 international patents. Additional patent applications are pending. When we consider it to be advantageous, we utilize our intellectual property portfolio and access the intellectual property of third parties by entering into commercial licenses and cross-licenses.

Governmental Regulation

Our products are subject to certain mandatory regulatory approvals in the United States, Canada, the European Union (EU) and other regions in which we operate. In the United States, the Federal

Communications Commission regulates many aspects of communications devices, including radiation of electromagnetic energy, biological safety and rules for devices to be connected to the telephone network. In Canada, similar regulations are administered by the Ministry of Industry, through Industry Canada. European Union directives provide the comparable regulatory guidance in Europe.

Wireless modems must be approved under these regulations by the relevant government authority prior to these products being offered for sale. We have obtained all necessary Federal Communications Commission, Industry Canada, European Union and other required regulatory approvals for the products we currently sell.

Additional Information Concerning Our Business

Sierra Wireless’s operations do not have a significant impact upon the environment. We have not made, and are not required to make, any significant capital expenditures to comply with environmental regulations. Working with the contract manufacturers who make our products and relevant component suppliers, we intend to ensure that our products that are sold in the EU comply with the EU directives that restrict the use of certain hazardous substances in electronic equipment sold in the EU after July 1, 2006.

Risk Factors

Our business is subject to significant risks and past performance is no guarantee of future performance. Some of the risks we face are:

We have incurred net losses and if our efforts to restore the business to profitability are not successful, we may be required to further restructure or take other actions and our share price may decline.

As a result of the reduction in our business in 2005, we incurred a loss of $36.5 million in the year. Our accumulated deficit at December 31, 2005 was $82.9 million. While we had earnings from operations for each of the previous two years ended December 31, 2004 and 2003, we incurred a loss from operations in each of the three fiscal years ended December 31, 2000, 2001 and 2002.

Our ability to achieve and maintain profitability in the future will depend on, among other things, the success of our restructuring, the continued sales of our current products and the successful development and commercialization of new products. If we do not return to profitability, our total losses will increase and we may be required to further restructure our operations or raise additional capital. Additional financing may not be available, and even if available, may not be on acceptable terms. We may seek to raise additional capital through an offering of common shares, preference shares or debt, which may result in dilution, and/or the issuance of securities with rights senior to the rights, of the holders of common shares. As a result, our share price may decline.

Our revenues and earnings may fluctuate from quarter to quarter, which could affect the market price of our common shares.

Our revenues and earnings may vary from quarter to quarter as a result of a number of factors, including:

• The timing of releases of our new products;

• The timing of substantial sales orders and OEM and carrier customer sell through;

• Design win cycles in our embedded module business;

• The amount of inventory held by our channel partners;

• Competition from other market participants;

• Possible cyclical fluctuations related to the evolution of wireless technologies;

• Possible delays in the manufacture or shipment of current or new products;

• Concentration in our customer base; and

• Possible delays or shortages in component supplies.

Because our operating expenses are determined based on anticipated sales, are generally fixed and are incurred throughout each fiscal quarter, any of the factors listed above could cause significant variations in our revenues and earnings in any given quarter. Therefore, our quarterly results are not necessarily indicative of our overall business, results of operations and financial condition. However, quarterly fluctuations in our revenues and earnings may affect the market price of our common shares.

We are subject to, and may in the future be subject to, certain class action lawsuits, which if decided against us, could require us to pay substantial judgments, settlements or other penalties.

In addition to being subject to litigation in the ordinary course of business, we are currently, and may in the future be, subject to class actions and other securities litigation and investigations. We expect that this type of litigation will be time consuming, expensive and distracting from the conduct of our daily business. It is possible that we will be required to pay substantial judgments, settlements or other penalties and incur expenses that could have a material adverse effect on our operating results, liquidity or financial position. Expenses incurred in connection with these lawsuits, which include substantial fees of lawyers and other professional advisors and our obligations to indemnify officers and directors who may be parties to such actions, could materially adversely affect our cash position. We do not know if any of this type of litigation and resulting expenses will be covered by insurance. In addition, these lawsuits may cause our insurance premiums to increase in future periods.

Competition from new or established wireless communication companies or from those with greater resources may prevent us from increasing or maintaining our market share and could result in price reductions and reduced revenues and gross margins.

The wireless industry is intensely competitive and subject to rapid technological change. We expect competition to intensify. More established and larger companies with greater financial, technical and marketing resources sell products that compete with ours. We also may introduce new products that will put us in direct competition with major new competitors. Existing or future competitors may be able to respond more quickly to technological developments and changes or may independently develop and patent technologies and products that are superior to ours or achieve greater acceptance due to factors such as more favorable pricing or more efficient sales channels. If we are unable to compete effectively with our competitors’ pricing strategies, technological advances and other initiatives, our market share and revenues may be reduced. As an example, during the first quarter of 2005, one of the factors that caused a significant decline in CDMA EV-DO PC card revenue was increased competition and loss of market share.

If demand for our current products declines and we are unable to launch successful new products, our revenues will decrease.

If the markets in which we compete fail to grow, or grow more slowly than we currently anticipate, or if we are unable to establish markets for our new products, it would significantly harm our

business, results of operations and financial condition. In addition, demand for one or all of our current products could decline as a result of competition, technological change or other factors.

If we are unable to design and develop new products that gain sufficient commercial acceptance, we may be unable to maintain our market share or to recover our research and development expenses and our revenues could decline.

We depend on designing, developing and marketing new products to achieve much of our future growth. Our ability to design, develop and market new products depends on a number of factors, including, but not limited to the following:

• Our ability to attract and retain skilled technical employees;

• The availability of critical components from third parties;

• Our ability to successfully complete the development of products in a timely manner; and

• Our ability to manufacture products at an acceptable price and quality.

A failure by us, or our suppliers, in any of these areas, or a failure of new products to obtain commercial acceptance, could mean we receive less revenue than we anticipate and we are unable to recover our research and development expenses, and could result in a decrease in the market price for our shares.

The loss of any of our material customers could adversely affect our revenues and profitability, and therefore shareholder value.

We depend on a small number of customers for a significant portion of our revenues. In the last three fiscal years, there have been five different customers that individually accounted for more than 10% of our revenues. In the year ended December 31, 2005, two customers individually accounted for more than 10% of our revenue and in the aggregate these two customers represented 36% of our revenue. If any of these customers reduce their business with us or suffer from business failure, our revenues and profitability could decline, perhaps materially.

We may not be able to continue to design products that meet our customer needs and, as a result, our revenue and profitability may decrease.

We develop products to meet our customers’ requirements but, particularly with original equipment manufacturers, current design wins do not guarantee future design wins. If we are unable or choose not to meet our customers’ future needs, we may not win their future business and our revenue and profitability may decrease.

We depend on a limited number of third parties to manufacture our products and supply key components. If they do not manufacture our products properly or cannot meet our needs in a timely manner, we may be unable to fulfill our product delivery obligations and our costs may increase, and our revenue and margins could decrease.

We outsource the manufacture of our products to a limited number of third parties and depend heavily on the ability of these manufacturers to meet our needs in a timely and satisfactory manner. Some components used by us may only be available from a small number of suppliers, in some cases from only one supplier. We currently rely on two manufacturers, either of which may terminate the manufacturing contract with us at the end of any contract year. Our reliance on third party manufacturers and suppliers subjects us to a number of risks, including the following:

• The absence of guaranteed manufacturing capacity;

• Reduced control over delivery schedules, production yields and costs; and

• Inability to control the amount of time and resources devoted to the manufacture of our products.

If we are unable to successfully manage any of these risks or to locate alternative or additional manufacturers or suppliers in a timely and cost-effective manner, we may not be able to deliver products in a timely manner. In addition, our results of operations could be harmed by increased costs, reduced revenues and reduced margins.

We do not have fixed-term employment agreements with our key personnel and the loss of any key personnel may harm our ability to compete effectively.

None of our executive officers or other key employees has entered into a fixed-term employment agreement. Our success depends in large part on the abilities and experience of our executive officers and other key employees. Competition for highly skilled management, technical, research and development and other key employees is intense in the wireless communications industry. We may not be able to retain our current executive officers or key employees and may not be able to hire and transition in a timely manner experienced and highly qualified additional executive officers and key employees as needed to achieve our business objectives. The loss of executive officers and key employees could disrupt our operations and our ability to compete effectively could be adversely affected.

We may have difficulty responding to changing technology, industry standards and customer preferences, which could cause us to be unable to recover our research and development expenses and lose revenues.

The wireless industry is characterized by rapid technological change. Our success will depend in part on our ability to develop products that keep pace with the continuing changes in technology, evolving industry standards and changing customer and end-user preferences and requirements. Our products embody complex technology that may not meet those standards, changes and preferences. In addition, wireless communications service providers require that wireless data systems deployed on their networks comply with their own standards, which may differ from the standards of other providers. We may be unable to successfully address these developments in a timely basis or at all. Our failure to respond quickly and cost-effectively to new developments through the development of new products or enhancements to existing products could cause us to be unable to recover significant research and development expenses and reduce our revenues.

We depend on third parties to offer wireless data and voice communications services for our products to operate.

Our products can only be used over wireless data and voice networks operated by third parties. In addition, our future growth depends, in part, on the successful deployment of next generation wireless data and voice networks by third parties for which we are developing products. If these network operators cease to offer effective and reliable service, or fail to market their services effectively, sales of our products will decline and our revenues will decrease.

Acquisitions of companies or technologies may result in disruptions to our business or may not achieve the anticipated benefits.

As part of our business strategy, we may acquire additional assets and businesses principally relating to or complementary to our current operations. Any acquisitions and/or mergers by us will be

accompanied by the risks commonly encountered in acquisitions of companies. These risks include, among other things:

• Exposure to unknown liabilities of acquired companies, including unknown litigation related to acts or omissions of our acquired company and/or its directors and officers prior to the acquisition;

• Higher than anticipated acquisition and integration costs and expenses;

• Effects of costs and expenses of acquiring and integrating new businesses on our operating results and financial condition;

• The difficulty and expense of integrating the operations and personnel of the companies;

• Disruption of our ongoing business;

• Diversion of management’s time and attention away from our remaining business during the integration process;

• Failure to maximize our financial and strategic position by the successful incorporation of acquired technology;

• The inability to implement uniform standards, controls, procedures and policies;

• The loss of key employees and customers as a result of changes in management;

• The incurrence of amortization expenses; and

• Possible dilution to our shareholders if the purchase price is paid in common shares or securities convertible into common shares.

In addition, geographic distances may make integration of businesses more difficult. We may not be successful in overcoming these risks or any other problems encountered in connection with any acquisitions. If realized, these risks could reduce shareholder value.

We may infringe the intellectual property rights of others.

The industry in which we operate has many participants that own, or claim to own, proprietary intellectual property. In the past we have received, and in the future may receive, claims from third parties alleging that we, and possibly our customers, violate their intellectual property rights. Rights to intellectual property can be difficult to verify and litigation may be necessary to establish whether or not we have infringed the intellectual property rights of others. In many cases, these third parties are companies with substantially greater resources than us, and they may be able to, and may choose to, pursue complex litigation to a greater degree than we could. Regardless of whether these infringement claims have merit or not, we may be subject to the following:

• We may be liable for potentially substantial damages, liabilities and litigation costs, including attorneys’ fees;

• We may be prohibited from further use of the intellectual property and may be required to cease selling our products that are subject to the claim;

• We may have to license the third party intellectual property, incurring royalty fees that may or may not be on commercially reasonable terms. In addition, there is no assurance that we will be able to successfully negotiate and obtain such a license from the third party;

• We may have to develop a non-infringing alternative, which could be costly and delay or result in the loss of sales. In addition, there is no assurance that we will be able to develop such a non-infringing alternative;

• The diversion of management’s attention and resources;

• Our relationships with customers may be adversely affected; and

• We may be required to indemnify our customers for certain costs and damages they incur in such a claim.

In the event of an unfavourable outcome in such a claim and our inability to either obtain a license from the third party or develop a non-infringing alternative, then our business, operating results and financial condition may be materially adversely affected and we may have to restructure our business.

Absent a specific claim for infringement of intellectual property, from time to time we have and expect to continue to license technology, intellectual property and software from third parties. There is no assurance that we will be able to maintain our third party licenses or obtain new licenses when required and this inability could materially adversely affect our business and operating results and the quality and functionality of our products. In addition, there is no assurance that third party licenses we execute will be on commercially reasonable terms.

Under purchase orders and contracts for the sale of our products we may provide indemnification to our customers for potential intellectual property infringement claims for which we may have no corresponding recourse against our third party licensors. This potential liability, if realized, could materially adversely affect our business, operating results and financial condition.

Misappropriation of our intellectual property could place us at a competitive disadvantage.

Our intellectual property is important to our success. We rely on a combination of patent protection, copyrights, trademarks, trade secrets, licenses, non-disclosure agreements and other contractual agreements to protect our intellectual property. Third parties may attempt to copy aspects of our products and technology or obtain information we regard as proprietary without our authorization. If we are unable to protect our intellectual property against unauthorized use by others it could have an adverse effect on our competitive position.

Our strategies to deter misappropriation could be inadequate due to the following risks:

• Non-recognition of the proprietary nature or inadequate protection of our methodologies in the United States, Canada or foreign countries;

• Undetected misappropriation of our intellectual property;

• The substantial legal and other costs of protecting and enforcing our rights in our intellectual property; and

• Development of similar technologies by our competitors.

In addition, we could be required to spend significant funds and our managerial resources could be diverted in order to defend our rights, which could disrupt our operations.

As our business expands internationally, we will be exposed to additional risks relating to international operations.

Our expansion into international operations exposes us to additional risks unique to such international markets, including the following:

• Increased credit management risks and greater difficulties in collecting accounts receivable;

• Unexpected changes in regulatory requirements, wireless communications standards, exchange rates, trading policies, tariffs and other barriers;

• Uncertainties of laws and enforcement relating to the protection of intellectual property;

• Language barriers; and

• Potential adverse tax consequences.

Furthermore, if we are unable to further develop distribution channels in Europe and the Asia-Pacific region we may not be able to grow our international operations and our ability to increase our revenue will be negatively impacted.

Government regulation could result in increased costs and inability to sell our products.

Our products are subject to certain mandatory regulatory approvals in the United States, Canada, the European Union and other regions in which we operate. In the United States, the Federal Communications Commission regulates many aspects of communications devices. In Canada, similar regulations are administered by the Ministry of Industry, through Industry Canada. European Union directives provide the comparable regulatory guidance in Europe. Although we have obtained all the necessary Federal Communications Commission, Industry Canada and other required approvals for the products we currently sell, we may not obtain approvals for future products on a timely basis, or at all. In addition, regulatory requirements may change or we may not be able to obtain regulatory approvals from countries other than the United States and Canada in which we may desire to sell products in the future.

Fluctuations in exchange rates between the United States dollar and other currencies, including the Canadian dollar may affect our operating results.

We are exposed to fluctuations in the exchange rate between the United States dollar and the Canadian dollar through our operations in Canada. To reduce our risk because of currency fluctuations, we purchase inventory, other cost of sales items and many of our services in United States dollars. If the Canadian dollar rises relative to the United States dollar, our operating results may be negatively impacted. To date, we have not entered into any foreign currency futures contracts as part of a hedging policy. We expect that as our business expands in Europe and the Asia-Pacific region, we will also be exposed to additional foreign currency transactions and to the associated currency risk. To date, we have not entered into any futures contracts.

DIVIDENDS

Since incorporation, we have not paid any dividends on our common shares. Our current intention is to reinvest earnings to finance the growth of our business. We do not anticipate that we will pay any dividends on our common shares in the immediate or foreseeable future.

DESCRIPTION OF CAPITAL STRUCTURE

Our authorized capital consists of an unlimited number of common shares, of which, at March 23, 2006, 25,502,170 are issued and outstanding, and an unlimited number of preference shares, issuable in series, of which none are issued and outstanding. Our board of directors is authorized to determine the designation, rights and restrictions to be attached to the preference shares upon issuance.

Holders of common shares are entitled to receive notice of any meeting of shareholders and to attend and vote at those meetings, except those meetings at which only the holders of shares of another class or of a particular series are entitled to vote. Each common share entitles its holder to one vote. Subject to the rights of the holders of preference shares, the holders of common shares are entitled to receive on a proportionate basis such dividends as our board of directors may declare out of funds legally available therefor. In the event of the dissolution, liquidation, winding up or other distribution of our assets, the holders of the common shares are entitled to receive on a proportionate basis all of our assets remaining after payment of all of our liabilities, subject to the rights of holders of preference shares.

The common shares carry no pre-emptive or conversion rights other than rights granted to holders of common shares under the Shareholders Rights Plan implemented and ratified by our shareholders on April 27, 2000 and re-adopted by our shareholders on April 28, 2003. The Shareholder Rights Plan is designed to encourage the fair treatment of our shareholders in connection with any take-over offer for our outstanding common shares. The Shareholder Rights Plan provides our board of directors and shareholders with 45 days, which is longer than provided by applicable laws, to fully consider any unsolicited take-over bid without undue pressure, to allow our board of directors, if appropriate, to consider other alternatives to maximize shareholder value and to allow additional time for competing bids to emerge. If a bid is made to all shareholders, is held open for at least 45 days and is accepted by shareholders holding more than 50% of the outstanding common shares, or is otherwise approved by our board of directors, then the Shareholder Rights Plan will not affect the rights of shareholders. Otherwise, all shareholders, except the parties making a take-over bid, will be able to acquire a number of additional common shares equal to 100% of their existing outstanding holdings at half the market price. Thus, any party making a take-over bid not permitted by the Shareholder Rights Plan could suffer significant dilution. The Shareholder Rights Plan will expire in accordance with its terms upon the termination of our 2006 annual meeting of shareholders. The directors have resolved to continue the Shareholder Rights Plan with certain minor amendments, by approving an amended and restated shareholder rights plan proposed to be dated April 25, 2006, subject to regulatory approval and approval of the shareholders.

AUDIT COMMITTEE

Mandate of the Audit Committee

The full text of the Mandate of the Audit Committee is set out below:

“1. Purpose and Scope

The audit committee (the “AC”) was established by the Board of Directors (“Board”) of Sierra Wireless Inc. (“Company”) to assist the Board in all issues relating to the oversight of the following:

• the Company’s whistleblower process; and

Reliance on Certain Exemptions

At no time since the commencement of the Company’s most recently completely financial year has the Company relied upon any exemption from MI 52-110 provided therein.

Audit Committee Oversight

At no time since the commencement of the Company’s most recently completed financial year was a recommendation of the Committee to nominate or compensate an external auditor not adopted by the board of directors of the Company.

Pre-approval Policies and Procedures

The Committee has the sole authority to review in advance and pre-approve all non-audit services to be provided to the Company or its subsidiaries by the Auditor, as well as all fees and other terms of engagement. The Committee may delegate to one or more members the authority to pre-approve non-audit services, provided a report is made to the Committee at its next scheduled meeting. All of the audit-related, tax and all other fees below were pre-approved by the Committee.

Auditor Independence

Sierra Wireless’s Audit Committee has concluded that the Auditors are independent under applicable rules and guidelines and, in particular, that the Auditors are free from conflicts of interest that could impair their objectivity in conducting the audit of the Company’s financial statements. The Audit Committee is required to approve all non-audit related services performed by our Auditors, and our Auditors are not permitted to perform services for us prohibited for an independent auditor under applicable Canadian and United States regulations, including the Sarbanes-Oxley Act.

Auditors’ Fees

In the 2005 and 2004 fiscal years, the fees paid to the Auditors were as follows:

	2005		2004
Audit Fees	$	297,000	$	288,000
Audit-Related Fees	23,000		31,000
Tax Fees	212,000		205,000
All Other Fees	Nil		Nil

Audit Fees

Audit fees for 2004 and 2005 are related to the audit of the year-end financial statements and the review of the Company’s quarterly financial statements and related filing documents including financial press releases.

Audit-Related Fees

Audit-related fees for 2005 are primarily for fees related to our Sarbanes-Oxley 404 documentation.

Tax Fees

Tax fees for 2005 and 2004 are primarily for the preparation of our Canadian and U.S. tax returns, assistance with tax planning and completion of transfer pricing studies.

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

The Company’s management is responsible for establishing and maintaining adequate disclosure controls and procedures for the Company. Towards that end, management has designed such disclosure controls and procedures, or caused such disclosure procedures to be designed under our supervision (a) to ensure that material information relating to the Company, including our consolidated subsidiaries, is made known to management by others within the Company and such subsidiaries; and (b) 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.

As of the end of the period covered by this annual report, the Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this annual report, the Company’s disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the Company’s filings with applicable securities regulatory authorities is reported, processed, summarized and reported within the time periods specified by the applicable securities commissions and stock exchanges and that all material information is accumulated and communicated to the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

The Company’s management, including the Chief Executive Officer and Chief Financial Officer, do not expect the Company’s disclosure controls will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur. Any design of any system of controls is based in part on certain assumptions about the likelihood of certain events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential conditions. Limitations in control systems include the realities that judgments and decision-making can be faulty and that breakdowns can occur because of simple error or mistake.

The Company is not yet required to be in compliance with the requirements of Section 404 of the Sarbanes-Oxley Act and, as such, is in the process of further evaluation and testing and, if required, enhancement of internal controls as a result of work being completed in connection with the requirements of section 404 of the Sarbanes-Oxley Act.

LEGAL PROCEEDINGS

Sierra Wireless America, Inc., as successor to AirPrime, Inc., along with other defendants, has been served with the complaint of Joshua Cohen and David Beardsley and others, filed in the U.S. District Court for the Central District of California for alleged violations of federal and state securities laws allegedly occurring prior to the time AirPrime, Inc. was acquired by the Company. The plaintiffs filed the third amended complaint on July 7, 2005. In November of 2005, the District Court dismissed the third amended complaint, without prejudice, with respect to the Company and most of the other defendants. The plaintiffs did not file a fourth amended complaint and sought an order from the District Court dismissing the federal actions as to all defendants, with prejudice for the purposes of final judgment, however without prejudice to the state claims in the third amended complaint. The District Court so ordered on February 27, 2006. The plaintiffs filed a notice of appeal to the U.S. Court of Appeals for the Ninth Circuit on March 8, 2006. We expect that it will be several months before they file their appeal

brief. In December 2005, we were served with a similar class action complaint of David Beardsley and others, filed in the Superior Court of the State of California, County of San Diego, for alleged violations of state securities laws in connection with the same alleged facts. On February 6, 2006, we filed a Motion to Stay the state court action pending resolution of the nearly identical federal action. We expect the Motion to Stay will be heard by the San Diego Superior Court in late March, 2006. We have given notice to our liability insurance carrier, which has agreed to pay our costs of defense that exceed the policy’s retention amount, subject to a reservation of rights in the event it is determined that the carrier has no liability for this litigation and without conceding any liability for payment of loss. We have also submitted an escrow claim notice under the escrow agreement dated August 12, 2003 relating to the acquisition of AirPrime and the escrow shareholders are disputing their obligations with respect to this complaint. Although there can be no assurance that an unfavourable outcome of the dispute would not have a material adverse effect on our operating results, liquidity or financial position, we believe the claims are without merit and will vigorously defend them. The Company has determined that it is not possible to establish a reasonable estimate of the possible loss, or range of possible loss, if any.

The Company and certain of our current and former officers were named as defendants in several class action complaints filed in the U.S. District Court for the Southern District of New York and the U.S. District Court for the Southern District of California for alleged violations of federal securities laws. The actions filed in the U.S. District Court for the Southern District of California have been transferred to the U.S. District Court for the Southern District of New York. By order dated December 16, 2005, the U.S. District Court for the Southern District of New York consolidated all of the actions for pretrial purposes, appointed co-lead plaintiffs in the consolidated action, approved the selection of co-lead counsel. Plaintiffs filed their consolidated amended complaint on February 21, 2006 and the defendants have until early April to file their Motion to Dismiss. We have given notice to our liability insurance carrier, which has agreed to pay our costs of defense that exceed the policy’s retention amount, subject to a reservation of rights in the event that it is determined that the carrier has no liability for this litigation. Although there can be no assurance that an unfavourable outcome would not have a material adverse effect on our operating results, liquidity or financial position, we believe the claims are without merit and will vigorously defend the lawsuits. The Company has determined that it is not possible to establish a reasonable estimate of the possible loss, or range of possible loss, if any. However, the Company believes that it is probable that the legal costs related to these complaints may exceed our policy retention amount of $1.0 million. Accordingly, we accrued $1.0 million in our results of operations for the year ended December 31, 2005.

On February 8, 2005, Sierra Wireless, Inc. was served with the first amended complaint of MLR, LLC filed in the U.S. District Court for the Northern District of Illinois Eastern Division for alleged patent infringement relating to our line of professional phones. We were added as a defendant in existing Civil Action No. 04 C 7044 MLR, LLC v. Kyocera Wireless Corporation and Novatel Wireless, Inc. Since that date, we have reached an agreement with MLR under which we received non-royalty bearing licenses to use all of MLR’s present and future patents for all of our products and MLR released us from all claims related to their patent portfolio. MLR has dismissed all claims against us in the lawsuit.

We are engaged in other legal actions in the ordinary course of business and believe that the ultimate outcome of these actions will not have a material adverse effect on our operating results, liquidity or financial position.

QUORUM EXEMPTION

The rules and regulations of the Nasdaq Stock Market applicable to the Company require each listed issuer to provide that a quorum for its shareholders’ meetings be at least 33 1/3 percent of the issuer’s outstanding shares. The Company has been granted an exemption from this requirement because it is

contrary to generally accepted business practices in Canada, the Company’s country of domicile. The Company has had the benefit of this exemption in the current and prior year.

In determining whether a requirement is contrary to generally accepted business practices, the Nasdaq rules generally look to the requirements of the primary market in the issuer’s country of domicile. The rules and policies of the Toronto Stock Exchange, the primary market in Canada, do not contain quorum requirements, and the Canada Business Corporations Act, the Corporation’s governing statute, defers to the quorum requirements contained in an issuer’s By-laws. Under the Company’s By-laws, a quorum for a meeting of the Company’s shareholders is two persons present in person, each being a shareholder entitled to vote thereat or a duly appointed proxyholder or representative for a shareholder so entitled.

REGISTRAR AND TRANSFER AGENT

The Registrar and Transfer Agent for the common shares in Canada is Computershare Investor Services Inc., 510 Burrard Street, Vancouver, British Columbia, and in the United States is Computershare Investor Services, Inc., 12039 West Alameda Parkway, Suite Z-2, Lakewood, Colorado. These offices and the principal offices of Computershare Investor Services Inc. in the City of Toronto maintain the register of common shares and can effect transfers and make deliveries of certificates for common shares.

MATERIAL CONTRACTS

There are no material contracts entered into outside of the Company’s ordinary course of business.

EXPERTS

KPMG LLP, independent chartered accountants, have audited our consolidated financial statements as at December 31, 2005 and 2004, and for each of the years in the three year period ended December 31, 2005 as set forth in their reports. KPMG LLP has advised the Company that they are independent with respect to the Company within the meaning of the Rules of Professional Conduct of the Institute of Chartered Accountants of British Columbia.
