Overview

We design, manufacture and sell solar module products that convert sunlight into electricity for a variety of uses. We are incorporated in Canada and conduct all of our manufacturing operations in China. Our products include a range of standard solar modules built to general specifications for use in a wide range of residential, commercial and industrial solar power generation systems. We also design and produce specialty solar modules and products based on our customers’ requirements. Specialty solar modules and products consist of customized modules that our customers incorporate into their own products, such as solar-powered bus stop lighting, and complete specialty products, such as solar-powered car battery chargers. Our products are sold primarily under our own brand name and also produced on an original equipment manufacturer, or OEM, basis for our customers. We also implement solar power development projects, primarily in conjunction with government organizations to provide solar power generation in rural areas of China.

We currently sell our products to customers located in various markets worldwide, including Germany, Spain, Canada, China and Japan. We currently sell our standard solar modules to distributors and system integrators. We sell our specialty solar modules and products directly to various manufacturers who either integrate these solar modules into their own products or sell and market them as part of their product portfolio.

We have grown rapidly since March 2002, when we sold our first solar module products. Our net revenues increased from $4.1 million in 2003 to $18.3 million in 2005, representing a compound annual growth rate, or CAGR, of 111.1%. Correspondingly, our net income increased from $761,245 to $3.8 million over the same period, representing a CAGR of 123.5%. Our net revenues increased from $7.0 million for the six months ended June 30, 2005 to $26.0 million over the same period in 2006. We sold 0.7 megawatts, or MW, 2.2 MW and 4.1 MW of our solar module products in 2003, 2004 and 2005, respectively. We sold 1.4 MW and 6.2 MW of our solar module products in the six months ended June 30, 2005 and 2006, respectively.

Industry Background

Solar power has recently emerged as one of the most rapidly growing renewable energy sources. Solar cells are fabricated from silicon wafers and convert sunlight into electricity through a process known as the photovoltaic effect. Solar modules, which are an array of interconnected solar cells encased in a weatherproof frame, are mounted in areas with direct exposure to the sun to generate electricity from sunlight. Solar power

systems, which are comprised of solar modules, related power electronics and other components, are used in residential, commercial and industrial applications and for customers who have no access to an electric utility grid.

According to Solarbuzz, an independent solar energy research firm, the global solar power market, as measured by annual solar system installations, increased from 345 MW in 2001 to 1,460 MW in 2005, representing a CAGR of 43.4%. During the same period, solar power industry revenues grew from approximately $2.4 billion in 2001 to approximately $9.8 billion in 2005, representing a CAGR of 42.2%. Solarbuzz projects that solar power industry revenues and solar system installations will reach $18.6 billion and 3,250 MW, respectively, by 2010. According to Solarbuzz, worldwide installations of solar power systems are expected to grow at a CAGR of 17.4% from 2005 to 2010, led by shipments for on-grid applications, where solar power is used to supplement a customer’s electricity purchased from the utility network. We believe growth in the near term will be constrained by the limited availability of high-purity silicon, but, according to Solarbuzz, is expected to accelerate after 2007.

We believe the following factors have driven and will continue to drive growth in the solar power industry:


	•	government incentives for solar power and other renewable energy sources;

	•	fossil fuel supply constraints and desire for energy security;

	•	growing awareness of the advantages of solar power, including its peak energy generation advantage, fuel risk advantage, scalability, reliability and environmentally friendly nature;

	•	advances in technologies making solar power more cost-efficient; and

	•	large market among underserved populations in rural areas of developing countries with little or no access to electricity.

Our Competitive Strengths

We believe that the following competitive strengths enable us to compete effectively and to capitalize on the rapid growth in the global solar power market:


	•	our ability to manage our supply chain, through sourcing of silicon feedstock, our silicon reclamation program and toll manufacturing arrangements, allows us to secure a cost-effective supply of solar cells;

	•	significant experience in the development and manufacture of high-margin specialty solar modules and products;

	•	flexible and low-cost manufacturing capability; and

	•	established senior management team with significant industry and international expertise.

Our Strategies

Our objective is to be a global leader in the development and manufacture of solar module products. We have developed the following strategies, based on our experience, to anticipate changes in the industry:


	•	pursue a balanced and diversified solar cell supply channel mix by entering into long-term cell supply contracts, toll manufacturing arrangements and in-house cell manufacturing;

	•	continue to proactively manage silicon raw material supply by securing long term silicon raw materials contracts, diversifying silicon supply sources and further developing and leveraging our silicon reclamation program;

	•	further diversify our geographic presence, customer base and product mix;


	•	enhance innovation and efficiency through R&D; and

	•	build a leading global brand.

Our Challenges

We believe that the following are some of the major challenges, risks and uncertainties that may materially affect us:


	•	our limited operating history may not serve as an adequate basis to judge our prospects and future results of operations;

	•	the current industry-wide shortage of high-purity silicon may constrain our revenue growth and decrease our margins and profitability;

	•	failure to secure a sufficient and cost-effective supply of solar cells could decrease our revenues and margins and prevent us from expanding as planned;

	•	the reduction or elimination of government subsidies and economic incentives for on-grid solar power applications could cause a reduction in demand for our products and decrease our revenues;

	•	we may not be able to compete successfully in our highly competitive market; and

	•	we may not be able to manage our expansion of operations effectively.

RECENT DEVELOPMENTS

For the three months ended September 30, 2006, our net revenues were $17.8 million, an increase of 3.2% from the prior quarter ended June 30, 2006 and 292.9% from the quarter ended September 30, 2005. We achieved these results following a strong quarter ended June 30, 2006, in which net revenues increased 96.2% from the prior quarter ended March 31, 2006. The increase from the third quarter of 2005 was due primarily to a significant increase in net revenues generated from the sale of our standard solar modules to our customers located in Europe.

For the three months ended September 30, 2006, our net income was $238,722, a decrease from the $2.5 million for the prior quarter ended June 30, 2006. The decrease was due primarily to the 122.2% increase in our total operating expenses from $1.8 million for the quarter ended June 30, 2006 to $4.0 million for the quarter ended September 30, 2006. That increase was attributable primarily to the increase in our share-based compensation expenses included as part of our selling expenses, general and administrative expenses and research and development expenses, from $0.2 million, $0.3 million and $12,681, respectively, for the quarter ended June 30, 2006 to $0.9 million, $1.9 million and $38,042, respectively, for the quarter ended September 30, 2006. The decrease was also due in part to income tax expense of $312,997 for the three months ended September 30, 2006 as compared to a tax gain of $183,502 for the prior quarter ended June 30, 2006.

RISK FACTORS

An investment in our common shares involves significant risks. You should carefully consider the risks described below before you decide to buy our common shares. If any of the following risks actually occurs, our business, prospects, financial condition and results of operations could be materially harmed, the trading price of our common shares could decline and you could lose all or part of your investment.

Risks Related to Our Company and Our Industry

Evaluating our business and prospects may be difficult because of our limited operating history.

There is limited historical information available about our company upon which you can base your evaluation of our business and prospects. We began business operations in October 2001 and shipped our first solar module products in March 2002. With the rapid growth of the solar power industry, we have experienced a high growth rate since our inception and, in particular, in 2004 and 2005 after we began to sell standard solar modules. As such our historical operating results may not provide a meaningful basis for evaluating our business, financial performance and prospects. We may not be able to achieve a similar growth rate in future periods and our business model at higher volumes is unproven. Accordingly, you should not rely on our results of operations for any prior periods as an indication of our future performance. You should consider our business and prospects in light of the risks, expenses and challenges that we will face as an early-stage company seeking to develop and manufacture new products in a rapidly growing market.

The current industry-wide shortage of high-purity silicon may constrain our revenue growth and decrease our margins and profitability.

We produce solar modules, which are an array of interconnected solar cells encased in a weatherproof package, and products that use solar modules. We do not currently produce solar cells ourselves but source them from other companies, either through direct purchases or toll manufacturing arrangements. High-purity silicon is an essential raw material in the production of solar cells and is also used in the semiconductor industry generally. There is currently an industry-wide shortage of high-purity silicon because of increased demand as a result of recent expansions of, and increased demand in, the solar power and semiconductor industries. The shortage of high-purity silicon has driven the overall increase in silicon feedstock prices. For example, according to a March 2006 report by Solarbuzz, the average long-term silicon feedstock contracted price increased from approximately $28-32 per kilogram in 2004 to $35-40 per kilogram in 2005, and is expected to increase to $45-50 per kilogram in 2006. In addition, according to Solarbuzz, spot prices for silicon feedstock were generally $60-80 per kilogram and reached in excess of $100 per kilogram as of March 2006. The shortage of high-purity silicon has also resulted in a shortage of, and significant price increases for, solar cells. According to Solarbuzz, the average selling price of solar cells increased from approximately €1.65-1.75 per watt in 2004 depending on the size of the cell and the type of technology used to approximately €2.20 per watt in 2005. Based on our experience, we believe the average price of silicon feedstock and solar cells to continue to increase. Any further increase in the demand from the semiconductor industry will compound the shortage and price increases. The shortage of high-purity silicon has constrained our revenue growth in the past and may continue to do so. Increases in the prices of silicon feedstock and solar cells have in the past increased our production costs and may impact our cost of revenues and net income in the future. The production of high-purity silicon is capital intensive and adding additional capacity requires significant lead time. While we are aware that several new facilities for the manufacture of high-purity silicon are under construction, we do not believe that the supply shortage will be remedied in the near term. We expect that demand for high-purity silicon will continue to outstrip supply for the foreseeable future. Furthermore, if solar cells are not available to us at commercially viable prices, this could adversely affect our margins and operating results. This would have a material negative impact on our business and operating results.

If we are unable to secure an adequate and cost effective supply of solar cells or reclaimable silicon, our revenue, margins and profits could be adversely affected.

Solar cells are the most important component of solar module products. We engage in supply chain management to secure a sufficient and cost-effective supply of solar cells through our sourcing of silicon feedstock, toll manufacturing arrangements with suppliers of ingots, wafers and cells and direct purchases from solar cell suppliers. While we have been able to secure silicon to meet our production needs in the past, due to ongoing industry shortages of silicon feedstock and solar cells, we cannot assure you that we will be able to continue to successfully manage our supply chain and secure an adequate and cost-effective supply of solar cells. For example, we have entered into three long-term contracts with silicon raw material suppliers, but we cannot assure you that we will be able to obtain adequate supplies from them under these contracts or from other suppliers in sufficient quantities and at commercially viable prices in the future. Moreover, toll manufacturing arrangements may not be available to us in the future or at higher volumes, in particular as high-purity silicon becomes more readily available in the future, which could have an adverse effect on our margins and profitability. Moreover, if we are unable to procure an adequate supply of solar cells, either through direct purchasing or through toll manufacturing arrangements or if solar cells are not available to us at commercially viable prices, we may be unable to meet demand for our products and could lose our customers and market share, and our margins and revenues could decline.

In addition, while we have been able to generate cost savings in the past through our recycling of reclaimable silicon, we cannot assure you that we will be able to secure sufficient reclaimable silicon at higher volumes in the future as we believe there is a limited supply of reclaimable silicon available in the market. If we are unable to secure a sufficient supply of reclaimable silicon, we will not be able to take advantage of the cost savings we achieve through our reclamation program and our margins could decline.

Because the markets in which we compete are highly competitive and many of our competitors have greater resources than us, we may not be able to compete successfully and we may lose or be unable to gain market share.

We compete with a large number of competitors in the solar module market. These include international competitors such as BP Solar International Inc., or BP Solar, Sharp Solar Corporation, or Sharp Solar, SolarWorld AG, or SolarWorld, and competitors located in China such as Suntech Power Holdings Co., Ltd. or Suntech Power. We expect to face increasing competition in the future. Further, many of our competitors are developing and are currently producing products based on new solar power technologies that may ultimately have costs similar to, or lower than, our projected costs. For example, some of our competitors are developing or currently producing products based on alternative solar technologies, such as thin film photovoltaic materials, which they believe will ultimately cost the same as or less than crystalline silicon technologies, which we use. Solar modules produced using thin film materials, such as amorphous silicon and cadmium telluride, require significantly less silicon to produce than crystalline silicon solar modules, such as our products, and are less susceptible to increases in silicon costs. We may also face competition from semiconductor manufacturers, several of which have already announced plans to start production of solar modules. In addition, the entry barriers are relatively low in the solar module manufacturing business given the low capital requirements and relatively less technological complexity involved. Due to the scarcity of high-purity silicon, supply chain management and access to financing are key entry barriers at present. However, if high-purity silicon capacity increases, these barriers may no longer exist and many new competitors may enter into the industry resulting in rapid industry fragmentation and loss of our market share.

Many of our current and potential competitors have longer operating histories, greater name recognition, access to larger customer bases and resources and significantly greater economies of scale. In addition, our competitors may have stronger relationships or may enter into exclusive relationships with some of the key distributors or system integrators to whom we sell our products. As a result, they may be able to respond more quickly to changing customer demand or to devote greater resources to the development, promotion and sales of their products than we can. The sale of our solar module products generated 97.7% and 99.7% of our net revenues in 2005 and for the six months ended June 30, 2006, respectively. Our

competitors with more diversified product offerings may be better positioned to withstand a decline in the demand for solar power products. Some of our competitors have also become vertically integrated, from upstream silicon wafer manufacturing to solar power system integration. It is possible that new competitors or alliances among existing competitors could emerge and rapidly acquire significant market share, which would harm our business. If we fail to compete successfully, our business would suffer and we may lose or be unable to gain market share.

In the immediate future, we believe that the competitive arena will continue to, and increasingly be contested on securing silicon feedstock and forming strategic relationships to secure a supply of solar cells. Many of our competitors have greater access to silicon raw materials and cell supply, including stronger strategic relationships with leading global and domestic silicon feedstock suppliers, or have upstream silicon wafer and cell manufacturing capabilities. We believe that as the supply of high-purity silicon stabilizes, the key to competing successfully in the industry will shift to more traditional sales and marketing activities. We have conducted very limited advertising in the past and cannot assure you that we will be able to make that transition successfully. The greater name recognition of some of our competitors may make it difficult for us to compete if and when this transition occurs. In addition, the solar power market in general competes with other sources of renewable energy and conventional solar power generation. If prices for conventional and other renewable energy resources decline, or if these resources enjoy greater policy support than solar power, the solar power market could suffer.

The reduction or elimination of government subsidies and economic incentives for solar power could cause demand for our products and our revenues, profits and margins to decline.

We believe that the near-term growth of the market, particularly for on-grid applications, depends in large part on the availability and size of government subsidies and economic incentives. Because a substantial portion of our sales is made in the on-grid market, the reduction or elimination of government subsidies and economic incentives may adversely hinder the growth of this market or result in increased price competition, which could cause our revenues to decline.

Today, the cost of solar power substantially exceeds the cost of power provided by the electric utility grid in many locations. Governments around the world have used different policy initiatives to accelerate the development and adoption of solar power and other renewable energy sources. Renewable energy policies are in place in the European Union, most notably Germany and Spain, certain countries in Asia, and many of the states in Australia and the United States. Examples of customer-focused financial incentives include capital cost rebates, feed-in tariffs, tax credits and net metering and other incentives to end users, distributors, system integrators and manufacturers of solar power products to promote the use of solar power in both on-grid and off-grid applications and to reduce dependency on other forms of energy. These government economic incentives could be reduced or eliminated altogether. Reductions in, or eliminations of, government subsidies and economic incentives before the solar power industry reaches a scale of economy sufficient to be cost-effective in a non-subsidized market place could result in decreased demand for our products and decrease our revenues, profits and margins.

Existing regulations and policies and changes to these regulations and policies may present technical, regulatory and economic barriers to the purchase and use of solar power products, which may significantly reduce demand for our products.

The market for electricity generation products is heavily influenced by government regulations and policies concerning the electric utility industry, as well as policies promulgated by electric utilities. These regulations and policies often relate to electricity pricing and technical interconnection of customer-owned electricity generation. In a number of countries, these regulations and policies have been modified and may continue to be modified. Customer purchases of, or further investment in the research and development of, alternative energy sources, including solar power technology, could be deterred by these regulations and policies, which could result in a significant reduction in the potential demand for our products. For example, without a regulatory mandated exception for solar power systems, utility customers are often charged interconnection or standby fees for putting distributed power generation on the electric utility grid. These fees could increase the cost to our customers of using our solar module products and make them less desirable,

thereby harming our business, prospects, results of operations and financial condition. In addition, pricing regulations and policies may place limits on our ability to increase the price of our solar module products in response to increases in our solar cells and silicon raw materials costs.

We anticipate that our products and their installation will be subject to oversight and regulation in accordance with national and local regulations relating to building codes, safety, environmental protection, utility interconnection and metering and related matters. It is difficult to track the requirements of individual jurisdictions and design products to comply with the varying standards. For example, the European Union’s Restriction of Hazardous Substances Directive, which took effect in July 2006, is a general directive. Each European Union member state will adopt its own enforcement and implementation policies using the directive as a guide. Therefore, there could be many different versions of this law that we will have to comply with to maintain or expand our sales in Europe. Any new government regulations or utility policies pertaining to our solar module products may result in significant additional expenses to us and, as a result, could cause a significant reduction in demand for our solar module products. In particular, any changes to existing regulations and policies or new regulations and policies in Germany could have a material adverse effect on our business and operating results. Sales to customers located in Germany accounted for 75.3% and 76.3% of our net revenues in 2005 and for the six months ended June 30, 2006, respectively, in part because of the availability and amounts of government subsidies and economic incentives in Germany.

The lack or unavailability of financing for on-grid and off-grid solar power applications could cause our sales to decline.

Our solar module products are used in both on-grid applications and off-grid applications. Off-grid applications are used where access to utility networks is not economical or physically feasible. In some developing countries, government agencies and the private sector have, from time to time, provided financing on preferential terms for rural electrification programs. We believe that the availability of financing programs could have a significant effect on the level of sales of solar modules for both on-grid and off-grid applications. If existing financing programs for on-grid and off-grid applications are eliminated or if financing programs are inaccessible or inadequate, the growth of the market for on-grid and off-grid applications may be materially and adversely affected, which could cause our sales to decline. In addition, a rise in interest rates could render existing financings more expensive and present an obstacle for potential financings that would otherwise spur the growth of the solar power industry, which could materially and adversely affect our business.

Our dependence on a limited number of solar cell and silicon raw material suppliers could prevent us from timely delivering our products to our customers in the required quantities, which could result in order cancellations and decreased revenues.

We purchase silicon raw materials and solar cells from a limited number of third-party suppliers. Our major suppliers of silicon raw materials include Kunical International Ltd., or Kunical International, of the United States and Luoyang Zhong Gui High Tech Co. Ltd., or Luoyang Zhong Gui, of China, which provide us specified minimum levels of silicon feedstock, Jiangxi Saiwei LDK Solar Energy High-Tech Limited, or LDK, which provides us specified minimum levels of solar wafers, Swiss Wafers AG, or Swiss Wafers, of Switzerland, which provides us specified minimum levels of solar cells and solar wafers. These suppliers may not be able to meet the specified minimum levels set forth in the contracts. We also have a limited number of suppliers from whom we either purchase directly or obtain solar cells through our toll manufacturing arrangements. If we fail to develop or maintain our relationships with these or our other suppliers, we may not be able to secure a supply of solar cells at cost-effective prices, or at all. If that were to occur, we may be unable to manufacture our products in a timely manner or our products may be manufactured only at a higher cost, and we could be prevented from delivering our products to our customers in the required quantities and at prices that are profitable. Problems of this kind could cause us to experience order cancellations and loss of market share and harm our reputation. The failure of a supplier to supply solar cells or silicon raw materials that meet our quality, quantity and cost requirements in a timely manner could impair our ability to manufacture our products or increase our costs, particularly if we are unable to obtain these

solar cells or silicon raw materials from alternative sources on a timely basis or on commercially reasonable terms. For example, in late 2005, one of our major suppliers of solar cells incurred serious fire damage at its facilities. This resulted in a signification reduction in the number of solar cells we were able to obtain during the succeeding five months, which in turn materially and adversely affected our net revenues for those months.

Our dependence on a limited number of customers and our lack of long-term contracts may cause significant fluctuations or declines in our revenues.

We currently sell a substantial portion of our solar module products to a limited number of customers, including distributors and system integrators, and various manufacturers who either integrate our products into their own products or sell them as part of their product portfolio. In 2005, our top five customers collectively accounted for approximately 68.2% of our net revenues. Bihler GmbH, or Bihler, and Sonn-en GmbH, or Sonn-en, contributed 36.8% and 14.0%, respectively, of our net revenues for the same time period. For the six months ended June 30, 2006, our top five customers collectively accounted for approximately 91.2% of our net revenues, and Iliotec Solar GmbH, or Iliotec, Schuco International KG, or Schuco, Instalaciones Pevafersa, or Pevafersa, and Bihler contributed 36.0%, 18.2%, 17.3% and 11.2%, respectively, of our net revenues for the same period. See “Business — Markets and Customers.” As is customary in the solar power industry, sales to our customers are typically made through non-exclusive, short-term arrangements. For example, our sales contracts with Bihler are typically for periods of three months and are in the forms of pro forma invoices and order confirmations. The delivery terms of these orders are ex-works, under which we fulfill our obligation to make delivery when we make the goods available to Bihler at our factory in China. We require Bihler to pay 20% to 30% of the purchase price as a prepayment for the goods covered by the pro forma invoice and require that the balance be paid by telex transfer in advance prior to each shipment. We anticipate that our dependence on a limited number of customers will continue for the foreseeable future. Consequently, any one of the following events may cause material fluctuations or declines in our revenues:


	•	reduction, delay or cancellation of orders from one or more of our significant customers;

	•	loss of one or more of our significant customers and our failure to identify additional or replacement customers; and

	•	failure of any of our significant customers to make timely payment for our products.

We may not be able to manage our expansion of operations effectively.

We commenced business operations in October 2001 and have grown rapidly since. We expect to continue to significantly expand our business to meet the growth in demand for our products, as well as to capture new market opportunities. To manage the potential growth of our operations, we will be required to improve our operational and financial systems and procedures and controls. Our rapid growth has strained our resources and made it difficult to maintain and update our internal procedures and controls as necessary to meet the expansion of our overall business. We must also increase production output, expand, train and manage our growing employee base, and successfully establish new subsidiaries to operate new or expanded facilities. Additionally, access to additional funds to support the expansion of our business may not always be available to us. Furthermore, our management will be required to maintain and expand our relationships with our customers, suppliers and other third parties.

We cannot assure you that our current and planned operations, personnel, systems and internal procedures and controls will be adequate to support our future growth. If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities, execute our business strategies or respond to competitive pressures.

If solar power technology is not suitable for widespread adoption, or sufficient demand for solar module products does not develop or takes longer to develop than we anticipate, our revenues may not continue to increase or may even decline, and we may be unable to sustain our profitability.

The solar power market is at a relatively early stage of development, and the extent of acceptance of solar module products is uncertain. Market data on the solar power industry are not as readily available as those for other more established industries where trends can be assessed more reliably from data gathered over a longer period of time. If solar power technology proves unsuitable for widespread adoption or if demand for solar module products fails to develop sufficiently, we may not be able to grow our business or generate sufficient revenues to sustain our profitability. In addition, demand for solar module products in our targeted markets, including Germany, Spain, the United States, Canada, China and Japan may not develop or may develop to a lesser extent than we anticipate. Many factors may affect the viability of widespread adoption of solar power technology and demand for solar module products, including:


	•	cost-effectiveness, performance and reliability of solar power products compared to conventional and other renewable energy sources and products;

	•	availability of government subsidies and incentives to support the development of the solar power industry;

	•	success of other alternative energy generation technologies, such as fuel cells, wind power, hydroelectric power and biomass;

	•	fluctuations in economic and market conditions that affect the viability of renewable energy sources, such as increases or decreases in the prices of oil and other fossil fuels; and

	•	deregulation of the electric power industry and broader energy industry.

Technological changes in the solar power industry could render our products uncompetitive or obsolete, which could reduce our market share and cause our revenues and profit to decline.

The solar power market is characterized by evolving technology standards that require improved features, such as more efficient and higher power output, improved aesthetics and smaller size. This requires us to develop new solar module products and enhancements for existing solar module products to keep pace with evolving industry standards and changing customer requirements. Technologies developed by others may prove more advantageous than ours for the commercialization of solar module products and may render our technology obsolete. Our failure to further refine our technology and develop and introduce new solar module products could cause our products to become uncompetitive or obsolete, which could reduce our market share and cause our revenues to decline. We will need to invest significant financial resources in research and development to maintain our market position, keep pace with technological advances in the solar power industry and effectively compete in the future.

If our future innovations fail to enable us to maintain or improve our competitive position, we may lose market share. If we are unable to successfully design, develop and introduce or bring to market competitive new solar module products, or enhance our existing solar module products, we may not be able to compete successfully. Competing solar power technologies may result in lower manufacturing costs or higher product performance than those expected from our solar module products. In addition, if we are unable to manage product transitions, our business and results of operations would be negatively affected.

Our business depends substantially on the continuing efforts of our executive officers, and our business may be severely disrupted if we lose their services.

Our future success depends substantially on the continued services of our executive officers, especially Dr. Shawn Qu, our chairman, president and chief executive officer, Bencheng Li, general manager of CSI Luoyang, Gregory Spanoudakis, our vice president of international sales and marketing, Robert Patterson, our vice president of corporate and product development and general manager of Canadian operations, and Bing Zhu, our chief financial officer. If one or more of our executive officers are unable or unwilling to continue in

their present positions, we may not be able to replace them readily, if at all. Therefore, our business may be severely disrupted, and we may incur additional expenses to recruit and retain new officers, in particular those with a significant mix of both international and China-based solar power industry experience as many of our current officers have. In addition, if any of our executives joins a competitor or forms a competing company, whether in violation of their agreements with us or otherwise, we may lose some of our customers.

We face risks associated with the marketing, distribution and sale of our solar module products internationally. If we are unable to effectively manage these risks, they could impair our ability to expand our business abroad.

In 2005 and for the six months ended June 30, 2006, we sold approximately 97.2% and 99.4%, respectively, of our products to customers located outside of China. The marketing, distribution and sale of our solar module products in the international markets expose us to a number of risks, including:


	•	fluctuations in the currency exchange rates of the Euro, U.S. dollar and RMB;

	•	difficulty in engaging and retaining distributors who are knowledgeable about and, can function effectively in, overseas markets;

	•	increased costs associated with maintaining marketing efforts in various countries;

	•	difficulty and cost relating to compliance with the different commercial and legal requirements of the overseas markets in which we offer our products;

	•	cultural, language and logistical barriers to working with customers in different countries; and

	•	trade barriers such as export requirements, tariffs, taxes and other restrictions and expenses, which could increase the prices of our products and make us less competitive in some countries.

Problems with product quality or product performance, including defects, in our products could damage our reputation, or result in a decrease in customers and revenue, unexpected expenses and loss of market share.

Our products may contain defects that are not detected until after they are shipped or are installed because we cannot test for all possible scenarios. These defects could cause us to incur significant costs, divert the attention of our personnel from product development efforts and significantly affect our customer relations and business reputation. If we deliver solar module products with errors or defects, or if there is a perception that our products contain errors or defects, our credibility and the market acceptance and sales of our solar module products could be harmed. In two instances in 2005, customers raised concerns about the stated versus actual performance output of some of our solar modules. We determined that both concerns resulted from differences in calibration methodologies and we resolved the issue with these customers. However, the corrective actions and procedures that we took may turn out to be inadequate to prevent further incidents of the same problem or to protect against future errors or defects. In addition, some of our ingot, wafer and cell suppliers with whom we have toll manufacturing arrangements have raised concerns about the quality and consistency of the silicon feedstock, in particular the reclaimable silicon that we recycle through our silicon reclamation program for re-use in the solar power industry, that we have provided to them for their ultimate conversion into solar cells. The use of reclaimed silicon in the solar power supply chain has an inherent risk as it is difficult to maintain the consistency and quality of reclaimed silicon at the same level as high-purity silicon. The successful use of reclaimed silicon requires extensive experience, know-how and additional quality control measures from both the provider of reclaimed silicon and the toll manufacturers. If we cannot successfully maintain the consistency and quality of the reclaimed silicon from our silicon reclamation program at an acceptable level, this may result in less efficient solar cells for our solar modules or in a lower conversion ratio of solar cells per ton of silicon feedstock that we provide, and may potentially delay and reduce our supply of solar cells. This may reduce or eliminate the cost advantages of recycling silicon through our silicon reclamation program. This could also cause problems with product quality or product performance, including defects in our products, and increase the cost of producing our products.

In addition, as we obtain the solar cells that we use in our products from third parties, either directly or through toll manufacturing arrangements, we have limited control over the quality of the solar cells we incorporate into our solar modules. Unlike solar modules, which are subject to certain uniform international standards, solar cells generally do not have uniform international standards, and it is often difficult to determine whether solar module product defects are a result of the solar cells or other components or reasons. We also rely on third party suppliers for other components that we use in our products, such as glass, frame and backing for our solar modules, and electronic components for our specialty solar modules and products. Furthermore, the solar cells and other components that we purchase from third party suppliers are typically sold to us without any, or with only limited, warranty. The possibility of future product failures could cause us to incur substantial expense to repair or replace defective products. Furthermore, widespread product failures may damage our market reputation, reduce our market share and cause our revenues to decline.

Since we cannot test our products for the duration of our standard warranty periods, we may be subject to unexpected warranty expense.

Our standard solar modules are typically sold with a two-year guarantee for defects in materials and workmanship and a 10-year and 25-year warranty against declines of more than 10.0% and 20.0%, respectively, of the initial minimum power generation capacity at the time of delivery. Our specialty solar modules and products are typically sold with a one-year guarantee against defects in materials and workmanship and may, depending on the characteristics of the product, contain a limited warranty of up to ten years, against declines of the minimum power generation capacity specified at the time of delivery. We believe our warranty periods are consistent with industry practice. Due to the long warranty period, we bear the risk of extensive warranty claims long after we have shipped our products and recognized revenue. We began selling specialty solar modules and products in 2002 and only began selling standard solar modules in 2004. Any increase in the defect rate of our products would cause us to increase the amount of warranty reserves and have a corresponding negative impact on our operating results. Although we conduct quality testing and inspection of our solar module products, our solar module products have not been and cannot be tested in an environment simulating the up to 25-year warranty periods. As a result, we may be subject to unexpected warranty expense and associated harm to our financial results as long as 25 years after the sale of our products.

Our future growth depends in part on our ability to make strategic acquisitions and investments and to establish and maintain strategic relationships, and our failure to do so could have a material adverse effect on our market penetration and revenue growth.

The solar power industry has only recently emerged as a high growth market and is currently experiencing shortages of its key component, high-purity silicon, due to rapid industry growth and demand. We believe it is critical that we continue to manage upstream silicon supply sources by, among other strategies, pursuing strategic acquisitions and investments in solar cell and silicon raw materials suppliers to secure a guaranteed supply and better control the specifications and quality of the materials delivered and fostering strategic relationships, particularly with silicon feedstock and solar cell suppliers. We cannot assure you, however, that we will be able to successfully make such strategic acquisitions and investments or establish strategic relationships with third parties that will prove to be effective for our business. Our inability in this regard could have a material adverse effect on our market penetration, our revenue growth and our profitability.

Strategic acquisitions, investments and relationships with third parties could subject us to a number of risks, including risks associated with sharing proprietary information and loss of control of operations that are material to our business. Moreover, strategic acquisitions, investments and relationships may be expensive to implement and subject us to the risk of non-performance by a counterparty, which may in turn lead to monetary losses that materially and adversely affect our business.

We may not succeed in developing a cost-effective solar cell manufacturing capability.

We plan to expand into areas further up the supply chain, including manufacturing solar cells to support our core solar module manufacturing business. We plan to complete our first solar cell production line in the first quarter of 2007 with commercial production targeted for the second quarter of 2007. We do not have any significant operating experience in this market and we will face significant challenges in the solar cell business. Manufacturing solar cells is a highly complex process and we may not be able to produce solar cells of sufficient quality to meet our solar module manufacturing standards. Minor deviations in the manufacturing process can cause substantial decreases in yield and in some cases cause production to be suspended or yield no output. We will need to make capital expenditures to purchase manufacturing equipment for solar cell production and will also need to make significant investments in research and development to keep pace with technological advances in solar power technology. The technologies, designs and customer preferences for solar cells change more rapidly, and solar cell product life cycles are shorter than those for solar modules. We may not be able to successfully address these new challenges. We will also face increased costs to comply with environmental laws and regulations. Any failure to successfully develop a cost-effective solar cell manufacturing capability may have a material adverse effect on our business and prospects.

In addition, although we intend to continue our toll manufacturing arrangements, if we engage in the large scale production of solar cells it may disrupt our existing relationships with solar cell suppliers. If solar cell suppliers discontinue or reduce the supply of solar cells to us, either through direct sales or through toll manufacturing arrangements, and we are not able to compensate for the loss or reduction with our own manufacturing of solar cells, our business and results of operations may be materially and adversely affected.

We may fail to successfully bring to market our new specialty solar modules and products, which may prevent us from achieving increased sales, margins and market share.

We expect to derive a greater portion of our revenues from sales of our new specialty solar modules and products and will increase our research and development expenses in connection with developing these products. If we fail to successfully develop our new specialty solar modules and products, we will likely be unable to recover the expenses that we will incur to develop these products and may be unable to increase our sales and market share and to increase our margins. Many of our new specialty solar modules and products have yet to receive market acceptance, and it is difficult to predict whether we will be successful in completing their development or whether they will be commercially successful. We may also need to develop new manufacturing processes that have yet to be tested and which may result in lower production output.

Our failure to protect our intellectual property rights in connection with new specialty solar modules and products may undermine our competitive position.

As we develop and bring to market new specialty solar modules and products, we may need to increase our expenses to protect our intellectual property and our failure to protect our intellectual property rights may undermine our competitive position. We currently use contractual arrangements with employees and trade secret protections to protect our intellectual property. Nevertheless, these afford only limited protection and the actions we take to protect our intellectual property rights as we develop new specialty solar modules and products may not be adequate. We currently only have one patent and two patent applications pending in China for products that makes up a relatively small percentage of our net revenues and one trademark application pending in China. Policing unauthorized use of proprietary technology can be difficult and expensive. Also, litigation, which can be costly and divert management attention, may be necessary to enforce our intellectual property rights, protect our trade secrets or determine the validity and scope of the proprietary rights of others.

We may be exposed to infringement, misappropriation or other claims by third parties, which, if determined adversely to us, could cause us to pay significant damage awards.

Our success depends on our ability to use and develop our technology and know-how and sell our solar module products without infringing the intellectual property or other rights of third parties. We do not have, and have not applied for, any patents for our proprietary technologies outside China, although we have sold, and expect to continue to sell, a substantial portion of our products outside China. The validity and scope of claims relating to solar power technology patents involve complex scientific, legal and factual questions and analysis and, therefore, may be highly uncertain. We may be subject to litigation involving claims of patent infringement or violation of intellectual property rights of third parties. In addition, we have not yet registered our trade name, “CSI,” outside of China, and our trademark application in China is still pending. As a result, we could be subject to trademark disputes and may not be able to police the unauthorized use of our trade name. The defense and prosecution of intellectual property suits, patent opposition proceedings and related legal and administrative proceedings can be both costly and time consuming and may significantly divert the efforts and resources of our technical and management personnel. An adverse determination in any such litigation or proceedings to which we may become a party could subject us to significant liability to third parties, require us to seek licenses from third parties, to pay ongoing royalties, or to redesign our products or subject us to injunctions prohibiting the manufacture and sale of our products or the use of our technologies. Protracted litigation could also result in our customers or potential customers deferring or limiting their purchase or use of our products until resolution of such litigation.

In addition, our competitors and other third parties may initiate legal proceedings against us or our employees that may strain our resources, divert our management attention and damage our reputation. For example, in March 2002, ICP Global Technologies Inc., or ICP Global, a manufacturer of solar power products, filed an action in the Superior Court of the Province of Quebec, Canada (Action No. 500-05 071241-028) against our vice president of international sales and marketing, Gregory Spanoudakis, and ATS Automation Tooling Systems Inc., or ATS. ICP Global subsequently amended the complaint to include us, our subsidiary, CSI Solartronics, and our chairman and chief executive officer, Dr. Shawn Qu, as defendants. The amended complaint contends that all of the defendants jointly engaged in unlawful conduct and unfair competition in directing a business opportunity away from ICP Global to us. Although there have been no meaningful discovery, court filings or communications from the plaintiff on this matter since early 2004, we cannot assure you that ICP Global will not move forward with this case or that the litigation will not be determined adversely to us. See “Our Business — Legal Proceedings” for more details. We also cannot assure you that similar proceedings will not occur in the future.

If we are unable to attract, train and retain technical personnel, our business may be materially and adversely affected.

Our future success depends, to a significant extent, on our ability to attract, train and retain technical personnel. Recruiting and retaining capable personnel, particularly those with expertise in the solar power industry, are vital to our success. There is substantial competition for qualified technical personnel, and there can be no assurance that we will be able to attract or retain our technical personnel. If we are unable to attract and retain qualified employees, our business may be materially and adversely affected.

Fluctuations in exchange rates could adversely affect our business.

Historically, a major portion of our sales were denominated in Euros, with the remainder in Renminbi and U.S. dollars. Since June 2005, substantially all of our sales contracts have been denominated in U.S. dollars. The major portion of our costs and expenses is denominated in U.S. dollars. We also incur a portion of our costs and expenses in Renminbi, primarily related to domestic sourcing of solar cells and silicon raw materials, toll manufacturing fees, labor costs and local overhead expenses. We also have loan arrangements with Chinese commercial banks that are denominated in Renminbi. Therefore, fluctuations in currency exchange rates could have a material adverse effect on our financial condition and results of operations. Fluctuations in exchange rates, particularly among the U.S. dollar, Renminbi and Euro, affect our gross and net profit margins and could result in fluctuations in foreign exchange and operating gains and

losses. We cannot predict the impact of future exchange rate fluctuations on our results of operations and we may incur net foreign currency losses in the future.

Product liability claims against us could result in adverse publicity and potentially significant monetary damages.

As with other solar module product manufacturers, we are exposed to risks associated with product liability claims if the use of our solar module products results in injury. Since our products generate electricity, it is possible that users could be injured or killed by our products as a result of product malfunctions, defects, improper installation or other causes. We only shipped our first products in March 2002 and, because of our limited operating history, we cannot predict whether product liability claims will be brought against us in the future or the effect of any resulting negative publicity on our business. Although we carry limited product liability insurance, we may not have adequate resources to satisfy a judgment if a successful claim is brought against us. The successful assertion of product liability claims against us could result in potentially significant monetary damages and require us to make significant payments. Even if the product liability claims against us are determined in our favor, we may suffer significant damage to our reputation.

Our quarterly operating results may fluctuate from period to period in the future.

Our quarterly operating results may fluctuate from period to period based on the seasonality of consumer spending and industry demand for solar power products. In addition, purchases of solar products tends to decrease during the winter months in our key markets, such as Germany, due to adverse weather conditions that can complicate the installation of solar power systems. As a result, you may not be able to rely on period to period comparisons of our operating results as an indication of our future performance. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Overview” for factors that are likely to cause our operating results to fluctuate.

Our founder, Dr. Shawn Qu, will have a substantial influence over our company and his interests may not be aligned with the interests of our other shareholders.

Dr. Shawn Qu, our founder, chairman and chief executive officer, currently beneficially owns 65.20% of our outstanding share capital and will beneficially own approximately 50.14% of our outstanding share capital upon completion of this offering. As such, Dr. Qu has, and will continue to have, substantial influence over our business, including decisions regarding mergers, consolidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and might reduce the price of our common shares. These actions may be taken even if they are opposed by our other shareholders, including those who purchase shares in this offering.

Compliance with environmental regulations can be expensive, and noncompliance with these regulations may result in adverse publicity and potentially significant monetary damages, fines and suspensions of our business operations.

We are required to comply with all national and local regulations regarding protection of the environment. We believe that our manufacturing processes do not generate any material levels of noise, waste water, gaseous wastes and other industrial wastes and that we are in compliance with present environmental protection requirements and have all necessary environmental permits to conduct our business as it is presently conducted. However, if more stringent regulations are adopted in the future, the costs of compliance with these new regulations could be substantial. For example, we increased our expenditures to comply with the European Union’s Restriction of Hazardous Substances Directive, which took effect in July 2006, by reducing the amount of lead and other restricted substances used in our solar module products. Furthermore, we may need to comply with the European Union’s Waste Electrical and Electronic Equipment Directive if we begin to sell specialty solar modules and products to customers located in Europe or if our customers

located in other markets demand that our products be compliant. In addition, as we expand our silicon reclamation program and research and development activities and expand into solar cell manufacturing, we may begin to generate material levels of noise, waste water, gaseous wastes and other industrial wastes. If we fail to comply with present or future environmental regulations, we may be required to pay substantial fines, suspend production or cease operations. Any failure by us to control the use of, or to restrict adequately the discharge of, hazardous substances could subject us to potentially significant monetary damages and fines or suspensions of our business operations.

We may not be successful in establishing our brand names among all consumers in important markets and the products we sell under our brand name may compete with the products we manufacture on an OEM basis for our customers.

We sell our products primarily under our own brand name and also on an OEM basis for our customers. In certain markets our brand may not be as prominent as other more established solar power vendors, and there can be no assurance that the “CSI” brand name or any of our potential future brand names, will gain acceptance among customers. Moreover, because the range of products we sell under our own brands and those we manufacture for our customers may be substantially similar, there can be no assurance that, currently or in the future, there will be no direct or indirect competition between products sold under the CSI brand, or any of our potential other future brands, and products we manufacture on an OEM basis. This could negatively affect our relationship with these customers.

If we grant employee share options, restricted shares or other share-based compensation in the future, our net income could be adversely affected.

We adopted a share incentive plan in 2006. As of the date of this prospectus, we have issued 1,337,770 share options and 566,190 restricted shares under our share incentive plan. In December 2004, the Financial Accounting Standards Board, or FASB, issued Statement of Financial Accounting Standards, or SFAS, No. 123R, “Share-Based Payment.” This statement, which became effective in our first quarter of 2006, will prescribe how we account for share-based compensation, and may have an adverse or negative impact on our results of operations or the price of our common shares. SFAS No. 123R requires us to recognize share-based compensation as compensation expense in the statement of operations based on the fair value of equity awards on the date of the grant, with the compensation expense recognized over the period in which the recipient is required to provide service in exchange for the equity award. This statement also requires us to adopt a fair value-based method for measuring the compensation expense related to share-based compensation. The additional expenses associated with share-based compensation may reduce the attractiveness of issuing share options or restricted shares under our share incentive plan. However, if we do not grant share options or restricted shares, or reduce the number of share options or restricted shares that we grant, we may not be able to attract and retain key personnel. If we grant more share options or restricted shares to attract and retain key personnel, the expenses associated with share-based compensation may adversely affect our net income.

There have been historical deficiencies with our internal controls and there remain areas of our internal and disclosure controls that require improvement. If we fail to maintain an effective system of internal controls, we may be unable to accurately report our financial results or prevent fraud, and investor confidence and the market price of our common shares may be adversely impacted.

When our auditors audited our financial statements as of and for the period ended December 31, 2005, they observed a number of deficiencies in our internal controls. These deficiencies included a lack of detail in our documented accounting policies, insufficient functionality of certain of our IT systems, and a limitation of tax, financial reporting, and accounting resources that could impact our financial reporting in accordance with accounting principles generally accepted in the U.S. These deficiencies in the design and operation of our internal controls could adversely affect our ability to record, process, summarize and report financial data consistent with the assertions of management in the financial statements. These historical deficiencies included several errors made by our accounting staff initially in preparing our 2005 financial statements. For

example, we had used assumptions in calculating the fair values of our convertible notes and the related derivatives and freestanding financial instruments that were inappropriate under U.S. GAAP and subsequently we had to revise the allocation of the proceeds from the issuance of the convertible notes. We also uncovered a record-keeping error with one of our foreign currency bank accounts, which resulted in an incorrect credit to our exchange gains/ losses. In addition, we did not properly apply U.S. GAAP in calculating the gain on an acquisition that we made in 2003, which resulted in an overstatement of extraordinary item by $93,446.

Following the identification of these deficiencies, we undertook remedial steps to address these deficiencies, including hiring additional staff, training our new and existing staff and installing new or improving current IT systems. In particular, we hired a financial controller, a manager of internal audit, a manager of financial control and an accounting manager. We continue to take additional steps to improve our internal controls and disclosure controls. If we are unable to implement solutions to deficiencies in our existing internal and disclosure controls and procedures, or if we fail to maintain an effective system of internal and disclosure controls in the future we may be unable to accurately report our financial results or prevent fraud and investor confidence and the market price of our common shares may be adversely impacted.

Risks Related to Doing Business in China

Uncertainties with respect to the Chinese legal system could have a material adverse effect on us.

We conduct substantially all of our manufacturing operations through our subsidiaries in China. These subsidiaries are generally subject to laws and regulations applicable to foreign investment in China and, in particular, laws applicable to wholly foreign-owned enterprises. The PRC legal system is based on written statutes. Prior court decisions may be cited for reference but have limited precedential value. Since 1979, PRC legislation and regulations have significantly enhanced the protections afforded to various forms of foreign investments in China. However, since these laws and regulations are relatively new and the PRC legal system continues to rapidly evolve, the interpretations of many laws, regulations and rules are not always uniform and enforcement of these laws, regulations and rules involve uncertainties, which may limit legal protections available to us. In addition, any litigation in China may be protracted and result in substantial costs and diversion of resources and management attention.

Fluctuation in the value of the Renminbi may have a material adverse effect on your investment.

The change in value of the Renminbi against the U.S. dollar, Euro and other currencies is affected by, among other things, changes in China’s political and economic conditions. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the Renminbi to the U.S. dollar. Under the new policy, the Renminbi is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. This change in policy has resulted in an approximately 5.0% appreciation of Renminbi against the U.S. dollar between July 21, 2005 and November 8, 2006. While the international reaction to the Renminbi revaluation has generally been positive, there remains significant international pressure on the PRC government to adopt an even more flexible currency policy, which could result in a further and more significant appreciation of the Renminbi against the U.S. dollar. As a portion of our costs and expenses is denominated in Renminbi, the revaluation in July 2005 and potential future revaluation has and could further increase our costs in U.S. dollar terms. In addition, as we rely entirely on dividends paid to us by our operating subsidiaries in China, any significant revaluation of the Renminbi may have a material adverse effect on our revenues and financial condition, and the value of, and any dividends payable on, our common shares. For example, to the extent that we need to convert U.S. dollars we receive from this offering into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we receive from the conversion. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our common shares or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount available to us.

Restrictions on currency exchange may limit our ability to receive and use our revenues effectively.

Certain portions of our revenue and expenses are denominated in Renminbi. If our revenues denominated in Renminbi increase or expenses denominated in Renminbi decrease in the future, we may need to convert a portion of our revenues into other currencies to meet our foreign currency obligations, including, among others, payment of dividends declared, if any, in respect of our common shares. Under China’s existing foreign exchange regulations, our PRC subsidiaries are able to pay dividends in foreign currencies, without prior approval from the State Administration of Foreign Exchange, or SAFE, by complying with certain procedural requirements. However, we cannot assure you that the PRC government will not take further measures in the future to restrict access to foreign currencies for current account transactions.

Foreign exchange transactions by our PRC subsidiaries under most capital accounts continue to be subject to significant foreign exchange controls and require the approval of PRC governmental authorities. In particular, if we finance our PRC subsidiaries by means of additional capital contributions, these capital contributions must be approved by certain government authorities including the Ministry of Commerce or its local counterparts. These limitations could affect the ability of our PRC subsidiaries to obtain foreign exchange through equity financing.

Our business benefits from certain PRC government incentives. Expiration of, or changes to, these incentives could have a material adverse effect on our operating results.

Under current PRC laws and regulations, a foreign invested enterprise, or FIE, in China is typically subject to enterprise income tax, or EIT, at the rate of 30% on taxable income, and local income tax at the rate of 3% on taxable income. The PRC government has provided various incentives to FIEs, such as each of our PRC subsidiaries, to encourage the development of foreign investments. Such incentives include reduced tax rates and other measures. FIEs that are determined by PRC tax authorities to be manufacturing companies with authorized terms of operation more than ten years, are eligible for: (i) a two-year exemption from EIT from their first profitable year; and (ii) a reduced EIT of 50% for the succeeding three years. CSI Solartronics is entitled to a preferential EIT rate of 24%, as it is a manufacturing enterprise located in a coastal economic development zone in Changshu. CSI Solartronic’s first profitable year was 2002 and it is currently paying an EIT rate of 12% until the end of 2006. CSI Solar Manufacturing is entitled to a preferential EIT rate of 15%. CSI Solar Manufacturing’s first profitable year was 2005 and it is exempt from EIT until 2006. It will be subject to an EIT rate of 7.5% from 2007 until 2009. CSI Solar Technologies, CSI Luoyang, CSI Solarchip and CSI Advanced have not made a profit and have therefore not applied for preferential tax treatment. If these subsidiaries turn profitable, they will apply for preferential tax rates and tax holidays. As these tax benefits expire, the effective tax rate of our PRC subsidiaries may increase significantly, and any increase of their EIT rates in the future could have a material adverse effect on our financial condition and results of operations.

There may be some uncertainty surrounding a recently adopted PRC regulation that requires certain offshore listings to be approved by the China Securities Regulatory Commission.

On August 8, 2006, six PRC regulatory agencies, including the China Securities Regulatory Commission, or CSRC, promulgated a regulation that took effect on September 8, 2006. This regulation, among other things, requires offshore special purpose vehicles, or SPVs, formed for listing purposes through acquisitions of PRC domestic companies and controlled by Chinese domestic companies or PRC individuals to obtain the approval of the CSRC prior to publicly listing their securities on an overseas stock exchange. On September 21, 2006, the CSRC published on its official website a notice specifying the documents and materials that are required to be submitted for obtaining CSRC approval. We believe, based on the advice of Chen & Co., our PRC counsel, that this regulation does not apply to us and that CSRC approval is not required because we are not an SPV covered by the new regulation as we are owned and controlled by non-PRC individual and entities, and all our PRC subsidiaries are foreign-funded and have been incorporated through our direct investment instead of acquisition. However, since the regulation has only recently been adopted, there may be some uncertainty as to how this regulation will be interpreted or implemented. If the CSRC or other PRC regulatory body subsequently determines that we need to obtain the CSRC’s approval for

this offering, we may face sanctions by the CSRC or other PRC regulatory agencies. In such event, these regulatory agencies may impose fines and penalties on our operations in the PRC, limit our operating privileges in the PRC, delay or restrict the repatriation of the proceeds from this offering into the PRC, or take other actions that could have a material adverse effect on our business, financial condition, results of operations, reputation and prospects, as well as the trading price of our common shares. The CSRC or other PRC regulatory agencies may also take actions requiring us, or making it advisable to us, to halt this offering before settlement and delivery of the common shares offered by this prospectus.

We face risks related to health epidemics and other outbreaks.

Our business could be adversely affected by the effects of avian flu or another epidemic or outbreak. In 2005 and 2006, there have been reports on the occurrences of avian flu in various parts of China, including a few confirmed human cases and deaths. Any prolonged recurrence of avian flu or other adverse public health developments in China may have a material adverse effect on our business operations. These could include our ability to travel or ship our products outside of China, as well as temporary closure of our manufacturing facilities. Such closures or travel or shipment restrictions would severely disrupt our business operations and adversely affect our results of operations. We have not adopted any written preventive measures or contingency plans to combat any future outbreak of avian flu or any other epidemic.

Risks Related to This Offering

There has been no public market for our common shares prior to this offering, and you may not be able to resell our common shares at or above the price you paid, or at all.

Prior to this initial public offering, there has been no public market for our common shares. Our common shares have been approved for listing on the Nasdaq Global Market. If an active trading market for our common shares does not develop after this offering, the market price and liquidity of our common shares will be materially and adversely affected. The initial public offering price for our common shares is determined by negotiations between us and the underwriters and may bear no relationship to the market price for our common shares after this initial public offering. We cannot assure you that an active trading market for our common shares will develop or that the market price of our common shares will not decline below the initial public offering price.

The market price for our common shares may be volatile.

The market price for our common shares is likely to be highly volatile and subject to wide fluctuations in response to factors including the following:


	•	announcements of technological or competitive developments;

	•	regulatory developments in our target markets affecting us, our customers or our competitors;

	•	actual or anticipated fluctuations in our quarterly operating results;

	•	changes in financial estimates by securities research analysts;

	•	changes in the economic performance or market valuations of other solar power companies;

	•	addition or departure of our executive officers and key research personnel;

	•	announcements regarding patent litigation or the issuance of patents to us or our competitors;

	•	fluctuations in the exchange rates between the U.S. dollar, the Euro and RMB;

	•	release or expiry of lock-up or other transfer restrictions on our outstanding common shares; and

	•	sales or perceived sales of additional common shares.

In addition, the securities market has from time to time experienced significant price and volume fluctuations that are not related to the operating performance of particular companies. These market fluctuations may also have a material adverse effect on the market price of our common shares.

Because the initial public offering price is substantially higher than our net tangible book value per share, you will incur immediate and substantial dilution.

If you purchase our common shares in this offering, you will pay more for the common shares than the amount paid by our existing shareholders for their common shares on a per share basis. As a result, you will experience immediate and substantial dilution of $11.32 per share (assuming no exercise by the underwriters their option to acquire additional common shares), representing the difference between our net tangible book value per share as of December 31, 2005, after giving effect to this offering and the initial public offering price of $15.00 per share. In addition, you may experience further dilution to the extent that our common shares are issued upon the exercise of share options.

Substantial future sales or perceived sales of our common shares in the public market could cause the price of our common shares to decline.

Sales of our common shares in the public market after this offering, or the perception that these sales could occur, could cause the market price of our common shares to decline. Upon completion of this offering, we will have 27,270,000 common shares outstanding (assuming no exercise by the underwriters of their option to acquire additional shares). All common shares sold in this offering will be freely transferable without restriction or additional registration under the Securities Act of 1933, as amended. The remaining common shares outstanding after this offering will be available for sale, upon the expiration of the 180-day lock-up period beginning from the date of this prospectus and subject to volume, holding period and other restrictions as applicable under Rule 144 and Rule 701 under the Securities Act. Any or all of these shares (other than those held by certain option holders) may be released prior to expiration of the lock-up period at the discretion of the joint lead underwriters. To the extent shares are released before the expiration of the lock-up period and these shares are sold into the market, the market price of our common shares could decline.

Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to you in the United States unless we register the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

Our articles of continuance contain anti-takeover provisions that could adversely affect the rights of holders of our common shares.

We intend to adopt an amendment to our articles of continuance that will become effective immediately upon the closing of this offering. We intend to include certain provisions in our amended articles of continuance that would limit the ability of others to acquire control of our company, and deprive our shareholders of the opportunity to sell their shares at a premium over the prevailing market price by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transactions.

We intend to include the following provisions in our amended articles of continuance that may have the effect of delaying or preventing a change of control of our company:


	•	Our board of directors has the authority, without approval by the shareholders, to issue an unlimited number of preferred shares in one or more series. Our board of directors may establish the number of shares to be included in each such series and may fix the designations, preferences, powers and other rights of the shares of a series of preferred shares.

	•	Our board of directors shall fix and may change the number of directors within the minimum and maximum number of directors provided for in our articles. Our board of directors may appoint one or more additional directors, who shall hold office for a term expiring no later than the close of the next annual meeting of shareholders, subject to the limitation that the total number of directors so appointed may not exceed one-third of the number of directors elected at the previous annual meeting of shareholders.

You may have difficulty enforcing judgments obtained against us.

We are a corporation organized under the laws of Canada and substantially all of our assets are located outside of the United States. Substantially all of our current operations are conducted in the PRC. In addition, most of our directors and officers, as well as the expert named in this prospectus, are nationals and residents of countries other than the United States. A substantial portion of the assets of these persons are located outside the United States. As a result, it may be difficult for you to effect service of process within the United States upon these persons. It may also be difficult for you to enforce in U.S. courts judgments obtained in U.S. courts based on the civil liability provisions of the U.S. federal securities laws against us and our officers and directors, most of whom are not residents in the United States and the substantial majority of whose assets are located outside of the United States. In addition, we have been advised by our Canadian counsel that a monetary judgment of a U.S. court predicated solely upon the civil liability provisions of U.S. federal securities laws would likely be enforceable in Canada if the U.S. court in which the judgment was obtained had a basis for jurisdiction in the matter that was recognized by a Canadian court for such purposes. We cannot assure you that this will be the case. It is unlikely that an action could be brought in Canada in the first instance for civil liability under U.S. federal securities laws. There is uncertainty as to whether the courts of the PRC would recognize or enforce judgments of U.S. courts against us or such persons predicated upon the civil liability provisions of the securities laws of the United States or any state. In addition, it is uncertain whether such PRC courts would be competent to hear original actions brought in the PRC against us or such persons predicated upon the securities laws of the United States or any state. See “Enforceability of Civil Liabilities.”

We may be classified as a passive foreign investment company, which could result in adverse U.S. federal income tax consequences to U.S. holders of our common shares.

Based on, among other things, the price of our common shares in this offering and the expected price of our common shares following this offering, we do not expect to be considered a “passive foreign investment company,” or PFIC, for U.S. federal income tax purposes for our current taxable year ending December 31, 2006, and we expect to operate in such a manner so as not to become a PFIC in future taxable years. However, we must make a separate determination each year as to whether we are a PFIC (after the close of each taxable year). Accordingly, we cannot assure you that we will not be a PFIC for our current taxable year ending December 31, 2006 or any future taxable year. A non-U.S. corporation will be considered a PFIC for any taxable year if either (1) at least 75% of its gross income is passive income or (2) at least 50% of the value of its assets is attributable to assets that produce or are held for the production of passive income. The market value of our assets may be determined in large part by the market price of our common shares, which is likely to fluctuate after this offering (and may fluctuate considerably given that market prices of technology companies have been especially volatile). In addition, the composition of our income and assets will be affected by how, and how quickly, we spend the cash we raise in this offering. If we were treated as a PFIC for any taxable year during which a U.S. person held a common share, certain adverse U.S. federal

income tax consequences could apply to such U.S. person. See “Taxation — United States Federal Taxation — Passive Foreign Investment Company.”

We will incur increased costs as a result of being a public company.

As a public company, we will incur a significantly higher level of legal, accounting and other expenses than we did as a private company. In addition, the Sarbanes-Oxley Act of 2002, as well as new rules subsequently implemented by the Securities and Exchange Commission, or the SEC, and the Nasdaq Global Market, have required changes in corporate governance practices of public companies. We expect these new rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. We are currently evaluating and monitoring developments with respect to these new rules, and we cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

RECENT DEVELOPMENTS

The following is a summary of our selected unaudited consolidated financial results for the three months ended September 30, 2006.

Net revenues were $17.8 million, a 3.2% increase from $17.3 million for the prior quarter ended June 30, 2006. We achieved these results following a strong quarter ended June 30, 2006, in which net revenues increased 96.2% from the prior quarter ended March 31, 2006. Net revenues for the three months ended September 30, 2006 increased by 292.9% from $4.5 million for the quarter ended September 30, 2005, due primarily to a significant increase in net revenues generated from the sale of our standard solar modules to our customers located in Europe.

Cost of revenues were $13.0 million, a 5.7% increase from $12.3 million for the prior quarter ended June 30, 2006. The increase was due primarily to the increase in the quantity of solar cells needed to produce an increased output of our standard solar modules and to a slight increase in the cost of materials for the production of our solar modules.

As a result of the foregoing, gross profit was $4.8 million as compared to $4.9 million for the prior quarter ended June 30, 2006.

Total operating expenses were $4.0 million, a 122.2% increase from $1.8 million for the prior quarter ended June 30, 2006. The increase was due primarily to the significant increases in share-based compensation expenses included in each of our selling expenses, general and administrative expenses and research and development expenses, as set forth below.

Share-based compensation expenses included in our cost of revenues, selling expenses, general and administrative expenses and research and development expenses were $72,499, $0.9 million, $1.9 million and $38,042, as compared to $24,166, $0.2 million, $0.3 million and $12,681, respectively, for the prior quarter ended June 30, 2006. We granted additional options and restricted shares to our personnel in the third quarter of 2006. In addition, we did not grant any options or restricted shares under our share incentive plan until May 30, 2006. As a result, share-based compensation expenses only comprised one month of our second quarter 2006 results as compared to the entirety of our third quarter 2006 results. For more information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Share-based Compensation Expenses.”

Income tax expense was $312,997, compared to a tax gain of $183,502 for the prior quarter ended June 30, 2006. The second quarter tax gain was due in part to the tax benefit from an increase in accrued warranty costs, which were recorded as deferred tax assets under U.S. GAAP.

As a result of the foregoing, net income was $238,722 as compared to net income of $2.5 million for the prior quarter ended June 30, 2006.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains many forward-looking statements that reflect our current expectations and views of future events. The forward-looking statements are contained principally in the sections entitled “Prospectus Summary,” “Risk Factors,” “Use of Proceeds,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Our Business.” Known and unknown risks, uncertainties and other factors, may cause our actual results, performance or achievements to be materially different from any future results, performances or achievements expressed or implied by the forward-looking statements. See “Risk Factors” for a discussion of some risk factors that may affect our business and results of operations. These risks are not exhaustive. Other sections of this prospectus may include additional factors that could adversely impact our business and financial performance. Moreover, because we operate in an emerging and evolving industry, new risk factors may emerge from time to time. It is not possible for our management to predict all risk factors, nor can we assess the impact of these factors on our business or the extent to which any factor, or combination of factors, may cause actual result to differ materially from those expressed or implied in any forward-looking statement.

In some cases, the forward-looking statements can be identified by words or phrases such as “may,” “will,” “expect,” “anticipate,” “aim,” “estimate,” “intend,” “plan,” “believe,” “potential,” “continue,” “is/are likely to” or other similar expressions. We have based the forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements include, among other things, statements relating to:


	•	our expectations regarding the worldwide demand for electricity and the market for solar power;

	•	our beliefs regarding lack of infrastructure reliability and long-term fossil fuel supply constraints;

	•	our beliefs regarding the inability of traditional fossil fuel-based generation technologies to meet the demand for electricity;

	•	our beliefs regarding the importance of environmentally friendly power generation;

	•	our expectations regarding governmental support for the deployment of solar power;

	•	our beliefs regarding the future shortage or availability of the supply of high-purity silicon;

	•	our beliefs regarding the acceleration of adoption of solar power technologies;

	•	our beliefs regarding the competitiveness of our solar module products;

	•	our expectations with respect to increased revenue growth and our ability to achieve profitability resulting from our supply chain management;

	•	our beliefs regarding the effects of environmental regulation;

	•	our beliefs regarding the changing competitive arena in the solar power industry;

	•	our future business development, results of operations and financial condition; and

	•	competition from other manufacturers of solar power products and conventional energy suppliers.

This prospectus also contains data related to the solar power market in several countries. These market data, including market data from Solarbuzz, include projections that are based on a number of assumptions. The solar power market may not grow at the rates projected by the market data, or at all. The failure of the market to grow at the projected rates may materially and adversely affect our business and the market price of our common shares. In addition, the rapidly changing nature of the solar power market subjects any projections or estimates relating to the growth prospects or future condition of our market to significant uncertainties. If any one or more of the assumptions underlying the market data proves to be incorrect, actual

results may differ from the projections based on these assumptions. You should not place undue reliance on these forward-looking statements.

The forward-looking statements made in this prospectus relate only to events or information as of the date on which the statements are made in this prospectus. Except as required by law, we undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, after the date on which the statements are made or to reflect the occurrence of unanticipated events. You should read this prospectus and the documents that we referenced in this prospectus and have filed as exhibits to the registration statement, of which this prospectus is a part, completely and with the understanding that our actual future results may be materially different from what we expect.

USE OF PROCEEDS

We will receive net proceeds for this offering of approximately $83.2 million, (or $93.0 million if the underwriters exercise the over-allotment option in full) after deducting the underwriting discounts, commissions and estimated offering expenses payable by us.

We intend to use the net proceeds we receive from this offering for the following purposes:


	•	approximately $30.0 million to purchase or prepay for solar cells and silicon raw materials;

	•	approximately $35.0 million for our expansion into solar cell manufacturing, including purchasing solar cell equipment and construction of our solar cell facilities, to support our core solar module business and for the expansion of our solar module manufacturing capabilities; and

	•	the remaining amount for other general corporate purposes.

We have not yet determined all of our anticipated expenditures and therefore cannot estimate the amounts to be used for each of the purposes discussed above. The amounts and timing of any expenditure will vary depending on the amount of cash generated by our operations, competitive and technological developments and the rate of growth, if any, of our business. Accordingly, our management will have significant discretion in the allocation of the net proceeds we will receive for this offering. Depending on future events and other changes in the business climate, we may determine at a later time to use the net proceeds for different purposes. Pending their use, we intend to place our net proceeds in short-term bank deposits.

We will not receive any of the proceeds from the sale of common shares by the selling shareholders.

CAPITALIZATION

The following table sets forth our capitalization, as of June 30, 2006:


	•	on an actual basis; and

	•	on a pro forma basis to give effect to (1) the conversion of all of our outstanding convertible notes into 5,542,005 common shares (after taking into account post-conversion share splits) that occurred on July 1, 2006 and (2) the issuance and sale of the 6,300,000 common shares by us in this offering, based on the initial public offering price of $15.00 per share, after deducting underwriting discounts, commissions and estimated offering expenses payable by us and assuming no exercise of the underwriters’ over-allotment option.

You should read this table together with our financial statements and the related notes included elsewhere in this prospectus and the information under “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

(2)	The proforma amount also includes $1,333,648 of deferred tax liabilities associated with the convertible notes. The deferred tax liabilities represent a component of the carrying value of the convertible notes upon conversion.

DILUTION

If you invest in our common shares, your interest will be diluted to the extent of the difference between the initial public offering price per common share and our net tangible book value per share after this offering. Dilution results from the fact that the initial public offering price per common share is substantially in excess of the book value per common share attributable to the existing shareholders for our presently outstanding common shares.

Our net tangible book value as of June 30, 2006 was approximately $23.7 million, or $1.13 per common share, after taking into account all share splits that occurred after June 30, 2006 and after giving effect to the conversion of conversion notes into 5,542,005 common shares on July 1, 2006. Net tangible book value represents the amount of our total consolidated tangible assets, minus the amount of our total consolidated liabilities. Without taking into account any other changes in such net tangible book value after June 30, 2006, other than to give effect to (i) the conversion of all of the convertible notes on July 1, 2006 into 5,542,005 common shares, and (ii) our sale of common shares in this offering at the initial public offering price of $15.00 per share, after deduction of underwriters discounts and commissions and estimated offering expenses of this offering payable by us, our adjusted net tangible book value per common share as of June 30, 2006 would have increased to $106.9 million or $3.92 per common share. This represents an immediate increase in net tangible book value of $2.79 per common share, to the existing shareholders, and an immediate dilution in net tangible book value of $11.08 per share to investors purchasing common shares in this offering. The following table illustrates such per share dilution:


Initial public offering price per common share	$	15.00
Net tangible book value per common share as of June 30, 2006	$	0.88
Pro forma net tangible book value per common share after giving effect to conversion of convertible notes	$	1.13
Increase in net tangible book value per common share attributable to this offering	$	2.79
Pro forma net tangible book value per common share after giving effect to the conversion of convertible notes and this offering	$	3.92
Pro forma amount of dilution in net tangible book value per common share to new investors in this offering after giving effect to the conversion of convertible notes	$	11.08

The following table summarizes, on a pro forma basis as of June 30, 2006, the differences between existing shareholders and the new investors with respect to the number of common shares purchased from us, the total consideration paid and the average price per common share paid before deducting the underwriting discounts and commissions and estimated offering expenses. The total number of common shares in the following table does not include common shares issuable upon the exercise of the over-allotment option granted to the underwriters. The information in the following table is illustrative only and the total consideration paid and the average price per common share for new investors is subject to adjustment based on the actual initial public offering price of our common shares and other terms of this offering determined at pricing.


	Common Shares										Average
	Purchased					Total Consideration					Price Per
											Common
	Number		Percent			Amount		Percent			Share

Existing shareholders		20,970,000		77	%	$	10,373,058		11	%	$	0.49
New investors		6,300,000		23	%		83,227,004		89	%		13.21

Total		27,270,000		100	%	$	93,600,062		100	%	$	3.43

The discussion and tables above assume no exercise of any outstanding share options. As of June 30, 2006, there were 970,795 common shares issuable upon exercise of outstanding share options at an exercise price of $2.12 and $4.29 per share, respectively, and in July and August we granted additional options exercisable into 366,975 common shares at exercise prices of $4.29, $12.00 and $15.00 per share. If all of these options had been exercised on June 30, 2006, after giving effect to the conversion of the convertible notes and this offering, our net tangible book value would have been approximately $112.5 million, or $3.93 per common share, and the dilution in net tangible book value to new investors would have been $11.07 per common share. In addition, the dilution to new investors will be $10.83 per common share, if the underwriters exercise their option to purchase additional common shares in full.

DIVIDEND POLICY

We have never declared or paid any dividends, nor do we have any present plan to pay any cash dividends on our common shares in the foreseeable future. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business.

Our board of directors has complete discretion on whether to pay dividends. Even if our board of directors decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant. Cash dividends on our common shares, if any, will be paid in U.S. dollars.

EXCHANGE RATE INFORMATION

Our business is primarily conducted in China and a portion of our expenses are denominated in RMB. Periodic reports made to shareholders will be expressed in U.S. dollars using the then current exchange rates. The conversion of RMB into U.S. dollars in this prospectus is based on the noon buying rate in The City of New York for cable transfers of RMB as certified for customs purposes by the Federal Reserve Bank of New York. Unless otherwise noted, all translations from RMB to U.S. dollars and from U.S. dollars to RMB in this prospectus were made at a rate of RMB8.0702 to $1.00, the noon buying rate in effect as of December 31, 2005. We make no representation that any RMB or U.S. dollar amounts could have been, or could be, converted into U.S. dollars or RMB, as the case may be, at any particular rate, the rates stated below, or at all. The PRC government imposes control over its foreign currency reserves in part through direct regulation of the conversion of RMB into foreign exchange and through restrictions on foreign trade. On November 8, 2006, the noon buying rate was RMB 7.8651 to $1.00.

The following table sets forth information concerning exchange rates between the RMB and the U.S. dollar for the periods indicated.

ENFORCEABILITY OF CIVIL LIABILITIES

We were incorporated as an Ontario corporation in October 2001 and were continued as a Canadian corporation under the CBCA in June 2006.

WeirFoulds LLP, our Canadian counsel, has advised us that a monetary judgment of a U.S. court predicated solely upon the civil liability provisions of U.S. federal securities laws would likely be enforceable in Canada if the U.S. court in which the judgment was obtained had a basis for jurisdiction in the matter that was recognized by a Canadian court for such purposes. We cannot assure you that this will be the case. It is unlikely that an action could be brought in Canada in the first instance for civil liability under the U.S. federal securities laws.

We have appointed CT Corporation System as our agent to receive service of process with respect to any action brought against us in the United States District Court for the Southern District of New York under the federal securities laws of the United States or of any state in the United States or any action brought against us in the Supreme Court of the State of New York in the County of New York under the securities laws of the State of New York.

Our constituent documents do not contain provisions requiring that disputes, including those arising under the securities laws of the United States, between us, our officers, directors and shareholders, be arbitrated.

Substantially all of our current operations are conducted in China, and substantially all of our assets are located in China. A majority of our directors and officers are nationals or residents of jurisdictions other than the United States and a substantial portion of their assets are located outside the United States. As a result, it may be difficult for a shareholder to effect service of process within the United States upon us or such persons, or to enforce against us or them judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States.

Chen & Co. Law Firm, our counsel as to PRC law, has advised us that there is uncertainty as to whether the courts of the PRC would:


	•	recognize or enforce judgments of United States courts obtained against us or our directors or officers predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States; or

	•	entertain original actions brought in each respective jurisdiction against us or our directors or officers predicated upon the securities laws of the United States or any state in the United States.

Chen & Co. Law Firm has advised us further that the recognition and enforcement of foreign judgments are provided for under the PRC Civil Procedures Law. PRC courts may recognize and enforce foreign judgments in accordance with the requirements of the PRC Civil Procedures Law based either on treaties between the PRC and the country where the judgment is made or on reciprocity between jurisdictions. China does not have any treaties or other arrangements that provide for the reciprocal recognition and enforcement of foreign judgments with the United States or Canada. As a result, it is generally difficult to recognize and enforce in China a judgment rendered by a court in either of these two jurisdictions.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the section entitled “Selected Consolidated Financial and Operating Data” and our consolidated financial statements and the related notes included elsewhere in this prospectus. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors” and elsewhere in this prospectus.

Overview

We design, manufacture and sell solar module products that convert sunlight into electricity for a variety of uses. We are incorporated in Canada and conduct all of our manufacturing operations in China. Our products include a range of standard solar modules built to general specifications for use in a wide range of residential, commercial and industrial solar power generation systems. We also design and produce specialty solar modules and products based on our customers’ requirements. Specialty solar modules and products consist of customized modules that our customers incorporate into their own products, such as solar-powered bus stop lighting, and complete specialty products, such as solar-powered car battery chargers. Our products are sold primarily under our own brand name and also produced on an OEM basis for our customers. We also implement solar power development projects, primarily in conjunction with government organizations to provide solar power generation in rural areas of China.

We have grown rapidly since March 2002, when we sold our first solar module products. Our net revenues increased from $4.1 million in 2003 to $18.3 million in 2005, representing a CAGR of 111.1%. Correspondingly, our net income increased from $761,245 to $3.8 million over the same period, representing a CAGR of 123.5%. Our net revenues increased from $7.0 million for the six months ended June 30, 2005 to $26.0 million over the same period in 2006. We sold 0.7 MW, 2.2 MW and 4.1 MW of our solar module products in 2003, 2004 and 2005, respectively. We sold 1.4 MW and 6.2 MW of our solar module products in the six months ended June 30, 2005 and 2006, respectively.

The most significant factors that affect our financial performance and results of operations are:


	•	availability and price of solar cells and silicon raw materials;

	•	industry demand;

	•	government subsidies; and

	•	product mix and pricing.

Availability and Price of Solar Cells and Silicon Raw Materials. We produce solar modules, which are an array of interconnected solar cells encased in a weatherproof frame, and products that use solar modules. Solar cells are the most important component for making solar modules. There is presently a shortage of solar cells as a result of a shortage of high-purity silicon caused primarily by the recent expansion of, and increased demand in, the solar power and semiconductor industries. The shortage of high-purity silicon has also contributed to significant price increases for solar cells. For example, according to Solarbuzz, the average long term silicon feedstock contracted price increased from approximately $28-32 per kilogram in 2004 to $35-40 per kilogram in 2005, and is expected to increase to $45-50 per kilogram in 2006. In addition, according to Solarbuzz, spot prices for silicon feedstock were generally $60-80 per kilogram and reached in excess of $100 per kilogram as of March 2006. According to Solarbuzz, the average selling price of solar cells increased from approximately €1.65-1.75 per watt in 2004, depending on the size of the cell and the type of technology used, to approximately €2.20 per watt in 2005. Based on our experience, we believe that the average prices of high-purity silicon and solar cells will continue to increase for the foreseeable future until the industry-wide high-purity silicon shortgage eases. Any increase in demand from the semiconductor industry will compound the shortage. Increases in the prices of high-purity silicon and solar cells have in the past increased our production costs and may continue to impact our cost of

revenues and net income in the future. In addition, we have experienced late delivery and supply shortages, which have affected our production.

Beginning in early 2005, we began managing our supply chain through toll manufacturing arrangements and our silicon reclamation program to secure a cost-effective supply of solar cells. This has allowed us to mitigate the effects of the industry-wide shortage of high-purity silicon, while reducing margin pressure. Currently, we secure our supply of solar cells primarily through our sourcing of silicon raw materials and toll manufacturing arrangements with suppliers of ingots, wafers and cells. We also purchase a limited amount of solar cells directly from our solar cell suppliers. In the past, we have been able to achieve cost savings through our toll manufacturing arrangements primarily because of our silicon reclamation processes. However, as the supply of high-purity silicon becomes more readily available in the future, toll manufacturing arrangements may not be available to us at higher or similar volumes, which could have an adverse effect on our margins and profitability.

We believe our current silicon raw material supply agreements and toll manufacturing arrangements will enable us to secure solar cells sufficient for a major portion of our estimated 2006 and a portion of our estimated 2007 production output. However, as we grow our business and as high-purity silicon becomes more readily available, we plan to diversify our cell supply channel mix to ensure flexibility in adapting to the future changes in the supply of and demand for solar cells. We plan to enter into long-term supply contracts and commence in-house manufacture of solar cells. We plan to complete our first solar cell production line in the first quarter of 2007 with commercial production targeted for the second quarter of 2007. Despite our plans to have a balanced and diversified solar cell supply channel mix, we cannot assure you that we will be able to secure sufficient quantities of solar cells and silicon raw materials to grow our revenues as planned or that we will be able to successfully develop a cost-effective solar cell manufacturing capability. See “Risk Factors — Risks Related to Our Company and Our Industry — The current industry wide shortage of high-purity silicon may constrain our revenue growth and decrease our gross margins and profitability” and “— We may not succeed in developing a cost-effective solar cell manufacturing capability.”

Given the current state of the industry, suppliers of solar cells and silicon raw materials typically require customers to make prepayments well in advance of their shipment. While we also typically require our customers to make prepayments, there is typically a lag between the time of our prepayment for solar cells and silicon raw materials and the time that our customers make prepayments to us. As a result, the purchase of solar cells and silicon feedstock, and other silicon raw materials through toll manufacturing arrangements, has required, and will continue to require, us to make significant working capital commitments beyond that generated from our cash flows from operations to support our estimated production output.

Industry and Seasonal Demand. Our business and revenue growth depends on demand for solar power. Although solar power technology has been used for several decades, the solar power market has grown significantly in the past several years. According to Solarbuzz, the global solar power market, as measured by annual solar system installations, increased from 345 MW in 2001 to 1,460 MW in 2005, representing a CAGR of 43.4%. During the same period, solar power industry revenues grew from approximately $2.4 billion in 2001 to approximately $9.8 billion in 2005, representing a CAGR of 42.2%. Solarbuzz projects that solar power industry revenues and solar system installations will reach $18.6 billion and 3,250 MW by 2010, respectively. Worldwide installations of solar power systems are expected to grow at an annual rate of 17.4% to 2010, led by on-grid shipments, according to Solarbuzz. We believe growth in the near term will be constrained by the limited availability of high-purity silicon, but is expected to accelerate after 2007. See “Business — Our Industry” for a more detailed discussion on the factors driving the growth of the solar power industry and the challenges that it faces. In addition, we believe that industry demand may be affected by seasonality. Demand tends to be lower in the first quarter than in the subsequent three quarters, primarily because of adverse weather conditions in our key markets, such as Germany, that complicate the installation of solar power systems.

Government Subsidies. We believe that the near-term growth of the market for on-grid applications depends in large part on the availability and size of government subsidies and economic incentives. Today, the cost of implementing and operating a solar power system substantially exceeds the cost of purchasing

power provided by the electric utility grid in many locations. As a result, federal, state and local governmental bodies in many countries, most notably Germany, Spain, the United States, Japan and China, have provided subsidies and economic incentives to reduce dependency on conventional sources of energy. These have come in the form of rebates, tax credits and other incentives to end users, distributors, system integrators and manufacturers of solar power products, to promote the use of solar energy in on-grid and, to a lesser extent, off-grid applications. The demand for our solar module products, in particular our standard solar modules, is affected significantly by these government subsidies and economic incentives. Any reductions or eliminations in government subsidies and economic incentives could reduce demand for our products and affect our revenues.

Product Mix and Pricing. We began selling our solar module products in March 2002 and all of our net revenues in 2002 and 2003 were generated from sales of specialty solar modules and products. We did not begin selling standard solar modules until 2004. By the end of 2004, the sale of standard solar modules represented 72.5% of our net revenues for the year. That percentage increased to 76.9% and 93.5% in 2005 and for the six months ended June 30, 2006, respectively. Our specialty solar modules and products generally generate higher margins compared with those generated by our standard solar modules, primarily because of the higher average selling price. We are able to charge a higher average selling price because of the greater complexity of design, the higher labor cost to design and manufacture specialty solar modules and products and the cost, if any, of purchasing additional components to complete the product. For example, the average selling price per watt of our standard solar modules was $3.92 for the year ended December 31, 2005, as compared to $5.13 per watt for our specialty solar modules and products over that same time period. While we expect sales of standard solar modules to drive our net revenues in the near future, we expect to increase sales of both our standard solar modules and our specialty solar modules and products going forward.

Our standard solar modules are priced based on the number of watts of electricity they can generate as well as overall demand in the solar power industry. We price our standard solar modules based on the prevailing market price at the time we enter into sales contracts with our customers, taking into account the size of the contract, the strength and history of our relationship with each customer and our solar cells and silicon raw materials costs. Over the past few years, the average selling prices for standard solar modules have risen year-to-year across the industry primarily because of high demand. Correspondingly, the average selling price of our standard solar module products increased from $3.62 per watt in 2004 to $3.92 per watt in 2005, and from $3.98 per watt for the six months ended June 30, 2005 to $4.09 per watt for the six months ended June 30, 2006. We generally enter into short-term sales contracts of approximately three months in term with our customers under which we are obligated to sell our products at set prices during the term of the contract. Given the strong industry demand for standard solar modules and increases in average selling prices per watt over recent years, the short-term nature of our contracts has allowed us to benefit from price increases. As demand and prices stabilize, we have begun, and will continue, to enter into longer-term sales contracts to help reduce our exposure to risks from decreases in standard solar module prices generally.

The price for our specialty solar modules and products is determined on a product-by-product basis, taking into account the complexity of design, direct labor costs in designing and manufacturing the product and the cost of purchasing additional components, if any, to complete the product. Specialty solar modules and products have shorter product life cycles, and product designs and customer preferences change more rapidly for specialty solar modules and products than for standard solar modules. As a result, the prices that we charge for these products are not directly comparable from year to year because our customers typically order these products for limited time periods. When a customer order ends, we may not be able to replace the customer order with orders for similarly-sized and -priced solar modules from that same customer or other customers. In addition, because we have a relatively small number of customers of specialty solar modules and products, sales of these products are susceptible to significant fluctuations. We sold 0.7 MW, 0.4 MW, 0.7 MW and 0.3 MW of these products in 2003, 2004, 2005 and for the six months ended June 30, 2006, respectively.

Overview of Financial Results

We evaluate our business using a variety of key financial measures.

Net Revenues

We generate revenues primarily from the sale of solar module products, consisting of standard solar modules and specialty solar modules and products. Solar module products accounted for 97.5%, 92.3%,97.7% and 99.7% of our net revenues in 2003, 2004, 2005 and for the six months ended June 30, 2006, respectively. We also generate revenues from the implementation of solar power development projects, primarily in conjunction with government organizations, to provide solar power generation in rural areas of China. To date, these have consisted of government-related assistance packages. Factors affecting our net revenues include average selling prices per watt, unit volume shipped, product demand and product mix. Our net revenues are net of business tax, value-added tax and returns and exchanges.

A small number of customers have historically accounted for a major portion of our net revenues. In 2004, 2005 and for the six months ended June 30, 2006, our top five customers during those periods collectively accounted for approximately 64.0%, 62.1% and 91.2% of our net revenues, and sales to our largest customer accounted for 16.3%, 36.8% and 36.0%, respectively. Our largest customers have changed from year to year, primarily because of the short product life cycles of our specialty solar modules and products and our recent entry into the standard solar module business. We did not make any sales in 2004 to our largest customer in 2005, which is a distributor of our standard solar modules. Changes in our product mix and strategic marketing decisions have also resulted in changes in our market concentration from year to year. The following table sets forth certain information relating to our total net revenues derived from our customers categorized by their geographic location for the periods indicated:

Cost of Revenues

Our cost of revenues consists primarily of the costs of:


	•	solar cells;

	•	other materials for the production of solar modules such as glass, aluminum frame and polymer backing;

	•	production labor, including salaries and benefits for manufacturing personnel;

	•	warranty costs;


	•	since the second quarter of 2006, share-based compensation expenses for options and restricted shares granted to our manufacturing employees and suppliers; and

	•	other materials, such as electronic components, used for the production of our specialty solar modules and products.

Solar cells make up the major portion of our cost of revenues. We purchase some of our solar cells directly from cell suppliers. The costs of solar cells that we directly purchase are the price that we pay to our suppliers. The substantial majority of our solar cells are obtained through toll manufacturing arrangements through which we source and provide silicon feedstock to suppliers of ingots, wafers and cells. These suppliers ultimately convert these silicon raw materials into the solar cells that we use for our production of solar modules. The costs of solar cells that we obtain through these toll manufacturing arrangements comprise of: (i) the costs of purchasing the silicon feedstock; (ii) labor costs incurred in inventory management; (iii) labor costs incurred in sorting the reclaimable silicon as part of our silicon reclamation program; and (iv) tolling fees charged by our suppliers under the tolling arrangements. The payments we make to our suppliers for the solar cells and the payment our suppliers make to us for the silicon feedstock that we source are generally settled separately. We do not include payments we receive for providing silicon feedstock as part of these toll manufacturing arrangements in our net revenues.

Our cost of revenues also includes warranty costs. We accrue 1.0% of our net revenues as warranty costs at the time revenues are recognized. Our standard solar modules are typically sold with a two-year guarantee for defects in materials and workmanship and a 10-year and 25-year warranty against declines of more than 10.0% and 20.0%, respectively, of the initial minimum power generation capacity at the time of delivery. Our specialty solar modules and products are typically sold with a one-year guarantee against defects and may, depending on the characteristics of the product, contain a limited warranty of up to ten years, against declines of the minimum power generation capacity specified at the time of delivery. We have not had any warranty claims to date. Our cost of revenues have historically increased as we increased our net revenues. We expect cost of revenues to increase as we increase our production volume.

Gross Profit/ Gross Margin

Our gross profit is affected by a number of factors, including the average selling prices for our products, product mix and our ability to cost-effectively manage our supply chain.

Our gross margin decreased from 42.3% in 2003 to 33.2% in 2004, primarily as a result of the change in product mix focus from specialty solar modules and products to standard solar modules in 2004 and the rising cost of solar cells due to high industry demand for solar power and shortages of silicon raw materials. Our specialty solar modules and products generally have higher margins compared to our standard solar modules. The primary reason for this is the higher average selling price per watt that we are generally able to charge for our specialty solar modules and products due to their more complex design.

Our gross margin increased from 33.2% in 2004 to 38.8% in 2005 as we initiated our supply chain management strategy in 2005. Our gross margin decreased from 43.9% for the six months ended June 30, 2005 to 28.5% for the six months ended June 30, 2006, primarily as a result of our changing product mix as we completed one of our large specialty solar module product contracts in mid-2005. Specialty solar modules and products, which tend to have higher margins than our standard solar modules, accounted for 31.6% and 6.0% of our net revenues for the six months ended June 30, 2005 and 2006, respectively. The decrease in gross margin is also attributable to the higher costs of solar cells in the six months ended June 30, 2006 and the substantial completion of one of our CIDA projects in mid-2005. A major component of our supply chain management involves the purchase of reclaimable silicon and processing it for reuse at a lower cost. This provides a significant cost advantage over the purchase of high-purity silicon. Our ability to select cost-effective suppliers for solar cells also provides us with cost savings. The successful use of reclaimed silicon requires extensive experience, know-how and additional quality control measures from both the provider of reclaimed silicon and the toll manufacturers. We must continue to maintain the consistency and quality of the reclaimed silicon from our silicon reclamation program at an acceptable level in order to continue receiving the cost advantages of recycling silicon through our silicon reclamation program.

We believe that we will face some margin compression in the sale of standard solar modules as high-purity silicon prices increase and as average selling prices stabilize and possibly decrease in the future. However, we expect this to be offset to a certain degree by increasing economies of scale and cost savings through the continued development and use of our silicon reclamation program and as we commence in-house manufacturing of solar cells. Expansion of our specialty solar modules and product business will be a driver of our gross margins in the future.

Operating Expenses

Our operating expenses include selling expenses, general and administrative expenses and research and development expenses. Our operating expenses have decreased in recent years as a percentage of our net revenues primarily due to economies of scale that we have achieved in connection with our revenue growth. We expect this trend to continue as our net revenues grow in the future.

Selling Expenses

Selling expenses consist primarily of salaries, sales commissions for sales and marketing personnel, advertising, promotional and other sales and marketing expenses. Since the second quarter of 2006, selling expenses have included share-based compensation expenses for options and restricted shares granted to our sales and marketing personnel. We have incurred only limited selling expenses to date as we have relied primarily on sales of standard solar modules in 2004, 2005 and for the first six months ended June 30, 2006, which have become increasingly commoditized. As we expand our business, we will increase our sales and marketing efforts and target companies in selected industry sectors. We expect our selling expenses to increase in the near term as we increase our sales efforts, hire additional sales personnel, target more markets and initiate additional marketing programs to reach our goal of building a leading global brand. However, assuming our net revenues increase at the rate we expect, over time we anticipate that our selling expenses will decrease as a percentage of our net revenues.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and benefits for our administrative and finance personnel, consulting and professional service fees, government and administration fees, exchange gain or loss, insurance fees and provisions for bad debt. Since the second quarter of 2006, our general and administrative expenses have included share-based compensation expenses for options and restricted shares granted to our general and administrative personnel, directors and consultants. We expect our general and administrative expense to increase as we hire additional personnel, upgrade our information technology infrastructure and incur expenses necessary to fund the anticipated growth of our business. We also expect general and administrative expenses to increase to support our operations as a public company, including compliance-related costs. However, assuming our net revenues increase at the rate we expect, over time we anticipate that our general and administrative expenses will decrease as a percentage of our net revenues.

Research and Development Expenses

Research and development expenses consist primarily of costs of raw materials used in our research and development activities, salaries and benefits for research and development personnel and prototype and equipment costs related to the design, development, testing and enhancement of our products and silicon reclamation program. Since the second quarter of 2006, our research and development activities have included share-based compensation expenses for options and restricted shares granted to our research and development employees. We expense our research and development costs as incurred. To date, our research and development expenses have been minor. A significant portion of our research and development activities have been in connection with our implementation of solar power development projects, primarily in conjunction with government organizations to provide solar power generation in rural areas of China. We have recorded the expenditures in connection with these solar power development projects in our cost of revenues.

We expect to devote more efforts to research and development and expect that our research and development expenses will increase in the near future as we hire additional research and development personnel, expand and promote innovation in our specialty solar modules and products portfolio, devote more resources towards using new technologies in our silicon reclamation program and expand into solar cell manufacturing. We will also continue to devote efforts to ensure that our products comply with the European Union’s Restriction of Hazardous Substances Directive, which took effect in July 2006, by reducing the amount of lead and other restricted substances used in our solar module products.

Share-based Compensation Expenses

We adopted our 2006 share incentive plan effective March 2006 and have granted a total of 574,150 options to purchase our common shares and 243,000 restricted shares as of September 15, 2006. For a description of the options and restricted shares granted, including the exercise prices and vesting periods, see “Management — 2006 Share Incentive Plan.” Under SFAS No. 123R, we are required to recognize share-based compensation as compensation expense in our statement of operations based on the fair value of equity awards on the date of the grant, with the compensation expense recognized over the period in which the recipient is required to provide service in exchange for the equity award. This statement also requires us to adopt a fair value-based method for measuring the compensation expense related to share-based compensation. For options granted to employees, we have recorded a compensation charge for the fair value of the options at the grant date. We then amortize share-based compensation expense over the vesting periods of the related options.

We have used Black-Scholes option pricing model to assess the fair value of our options. We used the Black-Scholes option pricing model to determine the fair value of our options. This option-pricing model requires the input of highly subjective assumptions, including the option’s expected life, estimated forfeitures and the price volatility of the underlying stock. We grant our restricted shares at their fair value which generally represents the fair value of an unrestricted share less a discount calculated based on the length of time the share is restricted.

We estimate our forfeitures based on past employee retention rates, our expectations of future retention rates, and we will prospectively revise our forfeiture rates based on actual history. Our share option and restricted share compensation charges may change based on changes to our actual forfeitures. In addition, a portion of the options were granted with exercise prices either at the price of this initial public offering or at 80% of the initial public offering price. As we did not know the actual offering price at the date of grant, we have estimated the expense based on our best estimate of that initial public offering price. Under U.S. GAAP, we are required to update those assumptions, and the related expenses, until the initial public offering occurs and the fair values are ultimately known.

For the first six months ended June 30, 2006, we recorded share-based compensation expenses of approximately $589,698. We have categorized these share-based compensation expenses in our (i) cost of revenues; (ii) selling expenses; (iii) general and administrative expenses; and (iv) research and development expenses, depending on the job functions of grantees to whom we granted the options or restricted shares. For the six months ended June 30, 2006, we recorded share-based compensation expenses of approximately $24,166, $229,007, $323,844 and $12,681 for each of those line items, respectively.

Assuming no change in the estimated forfeiture rates, our total share-based compensation expenses for future periods in respect of the equity awards that we have granted to date is as follows:


Period	US$

Three Months Ended September 30, 2006		2,904,488
Three Months Ended December 31, 2006		2,686,865
Year Ended December 31, 2007		8,283,309
Year Ended December 31, 2008		5,262,893
Year Ended December 31, 2009		4,245,135
Year Ended December 31, 2010		1,304,467

Given the preliminary nature of our estimates, our actual share-based compensation expenses may be materially different from our current expectations. In addition to the subjective assumptions and estimates discussed above, see “Forward-Looking Statements” for information regarding the various risks and uncertainties inherent in estimates of this type.

In determining the fair value of our common shares, we considered the guidance prescribed by the AICPA Audit and Accounting Practice Aid “Valuation of Privately-Held-Company Equity Securities Issued as Compensation”, or the Practice Aid. Specifically, paragraph 16 of the Practice Aid indicates a hierarchy in deciding on the type of valuation to perform and the valuation specialist to use. We have followed the “level A” recommendation of the Practice Aid by establishing the fair value of the common shares as of various dates in 2005 and 2006 in contemporaneous valuations by an independent valuation firm American Appraisal China Limited, or American Appraisal.

The following table shows the grant date and terms of share options and restricted shares granted to our employees, directors and other individuals from May 30, 2006 until September 2006 and the fair value of our common shares as of the date of each grant without taking into account any post-grant share splits.

	*	Shares used in calculation include common shares outstanding as of such date and all restricted shares granted as of such date. On July 1, 2006, all of our outstanding convertible notes were converted into common shares and we implemented a 1 for 1.16830772 share split that applied to all outstanding common shares but not the options or restricted shares. On October 2006, we implemented a 1 for 2.33 share split. See “Description of Share Capital — History of Securities Issuances.”

Determining the fair value of our common shares requires making complex and subjective judgments regarding projected financial and operating results, our unique business risks, the liquidity of our shares and our operating history and prospects at the time of grant. American Appraisal used a combination of the income approach and the guideline company approach to assess the fair value of our common shares. For the income approach, American Appraisal utilized a weighted discounted cash flow, or DCF, analysis based on our projected cash flows through 2010 in different scenarios. The cash flow projections were formulated to take into consideration the nature of our company, our relatively limited operating history, the growth of our operations and the business risks facing our company. Under the guideline company approach, American Appraisal analyzed the financial ratios and market price data of comparable companies. Nine comparable companies were selected primarily based on the nature of the business, the geographical location and the consideration of other market participants. The nine companies selected are primarily engaged in the solar power industry. American Appraisal determined market multiples of the guideline companies based on the latest available financial information, then adjusted those market multiples to take into account our growth and business risks. The market multiple was then applied to our performance indicators and discounted to reflect the lack of marketability.

In addition to business specific assumptions, American Appraisal relied on the following major assumptions in calculating the fair values of our common shares, including:


	•	Weight of income and guideline company multiples: American Appraisal assigned 60% weight to the income approach and 40% weight to the guideline company multiples approach because we had achieved better visibility of future earnings at the time, which made the income approach more meaningful.

	•	Weighted average costs of capital, or WACC: WACC of 17-18% was used. This was the combined result of the changes in risk-free rate, industry average beta, and our company-specific risk premium that reflects the risk associated with achieving projections at various stages of development.

	•	Capital market valuation multiples: American Appraisal obtained and assessed updated capital market valuation data of nine comparable companies.

	•	Lack of Marketability Discount, or LOMD: American Appraisal quantified the LOMD by the option-pricing method. This model considered the size of our company, the volatility factor of comparable companies in the solar power sector and the expected time to this initial public offering. In addition, the floatation cost and comparable restricted stock studies were also considered. The LOMD applied gradually decreased from 16% in November 2005 to 6% in June 2006 as the expected initial public offering date approached.

The increase in the fair value of our common shares since November 30, 2005, the date we issued convertible notes with a conversion price of $4.94 per share, is primarily attributable to increased projections of our future revenues and net income. Since November 30, 2005, we had achieved various milestones that increased the likelihood that we would obtain the necessary funding and resources to meet future financial projections. These milestones include:


	•	consistent quarterly revenue growth in 2005, including increased total revenues in 2005 of almost twice that achieved in 2004;

	•	our rapid and substantial expansion in sales and production of module products from 2.2 MW in 2004 to 4.1 MW in 2005, evidencing the viability of our business strategy and execution capability;

	•	further quarter-on-quarter growth in revenues from $6.8 million for the three months ended December 31, 2005 to $8.8 million for the three months ended March 31, 2006, despite historical seasonality effects during the first quarter of each year;


	•	revenues in the first half of 2006 that exceeded total revenues in the full year 2005 by 45%, as well as significant quarter-on-quarter growth from $8.8 million for the three months ended March 31, 2006 to $17.3 million for the three months ended June 30, 2006;

	•	production output on a megawatt basis in the first half of 2006 that exceeded production for the full year 2005;

	•	receipt of third-party guaranteed loans of RMB 105 million ($10.5 million) used to secure raw materials and fund construction of our new solar cell manufacturing facility; and

	•	finalization of several large supply agreements in 2006 to support our production expansion plans, including a five-year wafer contract with LDK, and several financing facilities, including a $3.3 million working capital facility.

In determining the fair value of its common shares, we have considered the guidance prescribed by the AICPA Audit and Accounting Practice Aid “Valuation of Privately-Held-Company Equity Securities Issued as Compensation”, or the Practice Aid, which provides that the value of a private enterprise during the period culminating in a successful initial public offering may increase significantly. Increases in enterprise value may be attributed partly to (a) changes in the amount and relative timing of future net cash flows (estimated and actual) as the enterprise successfully executes its business plan and responds to risks and opportunities in the market, and (b) a reduction in the risk associated with achieving projected results (or, from another perspective, narrowing the range of possible future results and increasing the likelihood of achieving desired results). In addition, the marketability provided by the offering itself increases enterprise value, because, among other things, it allows the enterprise access to the public capital markets. Moreover, macroeconomic factors also may affect the extent to which an enterprise’s value changes during the period culminating in its successful initial public offering. As our preparation for this offering progressed through 2006, the likelihood that we would benefit from an initial public offering and achieve a public market valuation also increased. Accordingly, we believe that the approach the independent appraiser has taken to value the common shares is appropriate and follows the recommendation set forth in the Practice Aid.

Interest Expenses

Interest expenses consist primarily of interest expenses with respect to our short-term loans and the accrued interest and non-cash charges on the convertible notes that we issued to HSBC HAV2 (III) Limited, or HSBC, and JAFCO Asia Technology Fund II, or JAFCO, which reference includes any affiliate to which it transferred shares issued upon conversion of the notes. HSBC and JAFCO are entitled to receive cash interest at 2% per annum. If the notes mature without being converted, HSBC and JAFCO are entitled to receive a premium at redemption equal to 10% per annum on the principal amount of the notes from their issue date to redemption. Discounts against the debt portion of the convertible notes were amortized over the maturity of the convertible notes using the straight-line method, which is not materially different from the effective interest rate method. We accrued non-cash charges in connection with the premium at redemption equal to 10% per annum on the principal amount of the notes from their issue date to redemption assuming the convertible notes had matured without being converted and amortization of discounts against the debt portion. Our non-cash charges of $134,666 and $706,320 in 2005 and for the six months ended June 30, 2006, respectively, consisted primarily of the amortization of discount on debt and the charges we incurred in connection with this premium.

Loss on Change in Fair Value of Derivatives

Loss on change in fair value of derivatives is associated with the convertible notes that we issued to HSBC and JAFCO. Prior to March 2006, at any time after the occurrence of a predefined event of default upon written demand from the note holders, the note holders were entitled to receive a premium of the higher of 12% per annum internal rate of return to the note holders or a market value-based return assuming full conversion of all convertible notes. Since the market value-based return created a net settlement provision, we were required to bifurcate the compound embedded derivatives and record them as derivatives or derivative financial instruments, which are stated at fair value on the issuance date and each financial reporting period

thereafter. Changes in fair value of the compound embedded derivatives were recorded in profits and losses as non-cash charges. The fair value of the convertible notes, excluding the compound embedded derivative liabilities, were determined with reference to a valuation conducted by American Appraisal. These non-cash charges amounted to $316,000 and $7.0 million in 2005 and for the six months ended June 30, 2006, respectively. In March 2006, this feature was eliminated such that an event of default entitles the note holders to receive a premium of 18% per annum internal rate of return to the note holders, effectively removing the net settlement provision. As a result, from March 2006, we no longer incur this charge.

Loss on Financial Instruments Related to Convertible Notes

In addition to the compound embedded derivatives which arose as part of the issuance of our convertible notes, our convertible notes also included freestanding financial instrument liabilities associated with the obligation to issue the second tranche of convertible notes to the investors and the investor’s option to subscribe for a third tranche of convertible notes. These financial instruments do not meet the definition of derivative instruments under US GAAP. However, the investors’ option to subscribe to the third tranche of convertible notes represents our written option which was required to be marked to market on the date of issuance and each financial reporting period thereafter. The changes in the fair value of the marked to market financial instrument was reported in profits and losses as a non-cash charge. These non-cash charges amounted to $263,089 in 2005 and $1.2 million for the six months ended June 30, 2006, all of which was incurred during the first quarter of 2006. We issued the second tranche convertible notes together with the convertible notes pursuant to the investors’ option in March 2006. As a result, from March 2006, we no longer incur this charge.

Income Tax Expense

We recognize deferred tax assets and liabilities for temporary differences between financial statement and income tax bases of assets and liabilities. Valuation allowances are provided against deferred tax assets when management cannot conclude that it is more likely than not that some portion or all of the deferred tax asset will be realized.

We are incorporated in Canada and are subject to Canadian federal and provincial corporate income taxes. As a Canadian controlled private corporation, we enjoy preferential tax rates for active business income carried on in Canada up to an annual limit. We will no longer be eligible for these preferential tax rates upon the listing of our common shares on the Nasdaq Global Market.

Under current PRC laws and regulations, an FIE in China is typically subject to EIT, at the rate of 30% on taxable income, and local income tax at the rate of 3% on taxable income. The PRC government has provided various incentives to FIEs, such as each of our PRC subsidiaries, to encourage the development of foreign investments. Such incentives include reduced tax rates and other measures. FIEs that are determined by PRC tax authorities to be manufacturing companies with authorized terms of operation of more than ten years, are eligible for: (i) a two-year exemption from EIT from their first profitable year; and (ii) a reduced EIT of 50% for the succeeding three years. CSI Solartronics is entitled to a preferential EIT rate of 24%, as it is a manufacturing enterprise located in a coastal economic development zone in Changshu. CSI Solartronic’s first profitable year was 2002 and it is currently paying an EIT rate of 12% until the end of 2006. CSI Solar Manufacturing is entitled to a preferential EIT rate of 15%. CSI Solar Manufacturing’s first profitable year was 2005 and it is exempt from EIT until 2006. It will be subject to a tax rate of 7.5% from 2007 until 2009. CSI Solar Technologies, CSI Luoyang, CSI Solarchip and CSI Advanced have not yet made a profit and have therefore not applied for preferential tax treatment. If these subsidiaries turn profitable, they will apply for preferential tax rates and tax holidays.

As these tax benefits expire, the effective tax rate of our PRC subsidiaries may increase significantly.

Extraordinary gain

In December 2003, we acquired the remaining 31.9% interests in CSI Changshu, in which we initially held 68.1% prior to the transaction. The acquisitions were recorded using the purchase method of accounting.

The acquired assets and liabilities were recorded at their fair value at the date of acquisition. An excess of fair value of acquired net assets over cost resulted because the fair value of the consideration paid in the form of cash and products was less than the fair value of the acquired net assets. We recognized an extraordinary gain as a result of this excess excluding (i) the amounts allocated as a pro rata reduction that otherwise would have been assigned to all of the acquired assets, except for financial assets other than investments, which are accounted for by the equity method, (ii) assets to be disposed of by sale, (iii) deferred tax assets, (iv) prepaid assets relating to pension or other postretirement benefit plans (v) and any other current assets.

Minority interests

Prior to our acquisitions of the remaining interests in CSI Changhsu, we recognized minority interests in 2003 to account for the 31.9% interests held by the other shareholders in CSI Changhsu.

Critical Accounting Policies

We prepare financial statements in accordance with U.S. GAAP, which requires us to make judgments, estimates and assumptions that affect (i) the reported amounts of our assets and liabilities, (ii) the disclosure of our contingent assets and liabilities at the end of each fiscal period and (iii) the reported amounts of revenues and expenses during each fiscal period. We continually evaluate these estimates based on our own historical experience, knowledge and assessment of current business and other conditions, our expectations regarding the future based on available information and reasonable assumptions, which together form our basis for making judgments about matters that are not readily apparent from other sources. Since the use of estimates is an integral component of the financial reporting process, our actual results could differ from those estimates. Some of our accounting policies require a higher degree of judgment than others in their application.

When reviewing our financial statements, you should consider (i) our selection of critical accounting policies, (ii) the judgment and other uncertainties affecting the application of such policies, (iii) the sensitivity of reported results to changes in conditions and assumptions. We believe the following accounting policies involve the most significant judgment and estimates used in the preparation of our financial statements.

Revenue Recognition

We record sales of our solar module products when the products are delivered and title has passed to our customers. We only recognize revenues when prices to the seller are fixed or determinable and collection is reasonably assured. We also recognize revenues from reimbursements of shipping and handling costs of products sold to customers. Our sales contracts typically contain our customary product warranties but do not contain post-shipment obligations or any return or credit provisions. A majority of our contracts provide that products are shipped under the term of free on board, or FOB, ex-works, or cost, insurance and freight, or CIF. Under FOB, we fulfill our obligation to make delivery when the goods have passed over the ship’s rail at the named port of shipment. From that point on, the customer has to bear all costs and risks of loss or damage to the goods. Under ex-works, we fulfill our obligation to make delivery when we have made the goods available at our premises to the customer. The customer bears all costs and risks involved in transporting the goods from our premises to their desired destination. Under CIF, we must pay the costs, marine insurance and freight necessary to bring the goods to the named port of destination but the risk of loss of or damage to the goods, as well as any additional costs due to events occurring after the time the goods have been delivered on board the vessel, is transferred to the customer when the goods pass the ship’s rail at the port of shipment. Most of our sales require that customers prepay before delivery has occurred. We record these prepayments as advances from customers until delivery is made. Our sales contracts typically contain our customary product warranties but do not contain any post-shipment obligations nor any return or credit provisions.

We also generate revenues from our implementation of solar power development projects, consisting primarily of government related assistance packages for our demonstration, promotion and feasibility projects and studies. The revenue is recognized when the projects are provided and accepted by the customers.

Warranty Cost

It is customary in our business and industry to warrant or guarantee the performance of our solar module products at certain levels of conversion efficiency for extended periods. Our standard solar modules are typically sold with a two-year guarantee for defects in materials and workmanship and a 10-year and 25-year warranty against declines of more than 10.0% and 20.0%, respectively, of the initial minimum power generation capacity at the time of delivery. Our specialty solar modules and products are typically sold with a one-year guarantee against defects in materials and workmanship and may, depending on the characteristics of the product, contain a limited warranty of up to ten years, against declines of the minimum power generation capacity specified at the time of delivery. We therefore maintain warranty reserves (recorded as accrued warranty costs) to cover potential liabilities that could arise from these guarantees and warranties. We accrue 1.0% of our net revenues as warranty costs at the time revenues are recognized and include that amount in our cost of revenues. Due to limited warranty claims to date, we accrue the estimated costs of warranties based primarily on an assessment of our competitors’ accrual history. Through our relationships with, and management’s experience working at, other solar power companies and on the basis of publicly available information regarding other solar power companies’ accrued warranty costs, we believe that accruing 1.0% of our net revenues as warranty costs is within the range of industry practice and is consistent with industry-standard accelerated testing, which assists us in estimating the long-term reliability of solar modules, estimates of failure rates from our quality review and other assumptions that we believe to be reasonable under the circumstances. However, although we conduct quality testing and inspection of our solar module products, our solar module products have not been and cannot be tested in an environment simulating the up to 25-year warranty periods. We have not experienced any material warranty claims to date in connection with declines of the power generation capacity of our solar modules. As is typical in the industry, however, we have experienced some claims concerning other defects or workmanship. We will prospectively revise our actual rate to the extent that actual warranty costs differ from the estimates.

Impairment of Long-lived Assets

We evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When these events occur, we measure impairment by comparing the carrying amount of the assets to future undiscounted net cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, we will recognize an impairment loss based on the fair value of the assets.

Allowance for Doubtful Accounts

We conduct credit evaluations of customers and generally do not require collateral or other security from our customers. We establish an allowance for doubtful accounts primarily based upon the age of the receivables and factors surrounding the credit risk of specific customers. With respect to advances to suppliers, our suppliers are primarily suppliers of solar cells and silicon raw materials. We perform ongoing credit evaluations of our suppliers’ financial conditions. We generally do not require collateral or security against advances to suppliers. However, we maintain a reserve for potential credit losses.

Inventories

Inventories are stated at the lower of cost or market. Cost is determined by the weighted average method. Cost of inventories consists of costs of direct materials, such as solar cells, glass, aluminum frame and polymer backing and other components, and where applicable, direct labor costs, tolling costs and any overhead that we incur in bringing the inventories to their present location and condition.

Adjustments are recorded to write down the cost of obsolete and excess inventory to the estimated market value based on historical and forecast demand.

We outsource portions of our manufacturing process, including converting silicon into ingots, cutting ingots into wafers, and converting wafers into solar cells, to various third-party manufacturers. These

outsourcing arrangements may or may not include transfer of title of the raw material inventory (silicon, ingots or wafers) to the third-party manufacturers. Such raw materials are recorded as raw materials inventory when purchased from suppliers.

For those outsourcing arrangements in which the title is not transferred, we maintain such inventory on our balance sheet as raw materials inventory while it is in physical possession of the third-party manufacturer. Upon receipt of the processed inventory, it is reclassified to work-in-process inventory and a processing fee is paid to the third-party manufacturer.

For those outsourcing arrangements, which are characterized as sales, in which title (including risk of loss) transfer to the third-party manufacturer, we are constructively obligated, through raw materials sales contracts and processed inventory purchase contracts which have been entered into simultaneously with the third-party manufacturers, to repurchase the inventory once processed. In this case, the raw material inventory remains classified as raw material inventory while in physical possession of the third-party manufacturer and cash is received, which is classified as advances from suppliers and customers on the balance sheet and not as revenue or deferred revenue. Cash payments for outsourcing arrangements, which require prepayment for repurchase of the processed inventory are classified as advances to suppliers on the balance sheet. There is no right of offset for these arrangements and accordingly, advances from suppliers and customers and advances to suppliers remain on the balance sheet until the processed inventory is repurchased. We do not recognize revenue until finished solar modules are delivered and title has passed to our customers.

Fair value of derivative and freestanding financial instruments

Valuations for derivative and freestanding financial instruments are typically based on the following hierarchy: (i) prices quoted on an organized market, (ii) prices obtained from other external sources such as brokers or over the counter third parties and (iii) valuation models and other techniques usually applied by market participants. Because our convertible notes and common shares were not publicly traded, we had relied solely on valuation models in determining these values.

We used a binomial model to value the conversion option and early redemption put option. The binomial model requires the input of assumptions, some of which are subjectively determined, such as the fair values of the common shares and the underlying notes, life of the option, the risk free interest rate over the period of the option, a standard derivation of expected volatility, and expected dividend yields. We determined the fair value of the underlying common shares based on valuations by American Appraisal. For a more detailed discussion on the assumptions involved in determining the fair value of our common shares, see “— Overview of Financial Results — Share-based Compensation Expenses.”

In determining the fair value of the freestanding note option, we used the Black-Scholes option pricing model. The option-pricing model requires the input of assumptions, some of which are subjectively determined, such as the fair value of the underlying convertible note, the exercise price of the option, the life of the option, the risk free rate over the period of the option, and a standard derivation of expected volatility.

In determining the fair value of the freestanding forward instrument, we used the fair value of the convertible note less the subscription price and interest forgone by not exercising the forward, discounted for the expected time the forward would be outstanding.

Changes to any of the assumptions used in the valuation model could materially impact the valuation results. A more detailed discussion on fair value calculations is reflected in Note 2(q) and Note 8 to our consolidated financial statements.

Income Taxes

Deferred income taxes are recognized for temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, net operating loss carry forwards and credits by applying enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in our opinion, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of the

relevant taxing authorities. The components of the deferred tax assets and liabilities are individually classified as current and non-current based on the characteristics of the underlying assets and liabilities.

Six Months Ended June 30, 2006 Compared to Six Months Ended June 30, 2005

Net Revenues. Our total net revenues increased significantly from $7.0 million for the six months ended June 30, 2005 to $26.0 million for the six months ended June 30, 2006. The increase was due primarily to a significant increase in net revenues generated from the sale of our solar module products from $6.6 million for the six months ended June 30, 2005 to $26.0 million for the six months ended June 30, 2006, which as a percentage of total revenues also increased from 93.9% to 99.7%. There was a significant decrease in other net revenues generated from our implementation of solar power development projects from $428,417 for the six months ended June 30, 2005 to $67,834 for the six months ended June 30, 2006, primarily due to our substantial completion of the remaining milestones in the “Solar Electrification for Western China” project in 2005. The volume of our solar module products sold increased from 1.4 MW for the six months ended June 30, 2005 to 6.2 MW for the six months ended June 30, 2006. Among our solar module product categories, the increase was driven primarily by sales of our standard solar modules. Net revenues from the sale of standard solar modules increased from $3.9 million for the six months ended June 30, 2005 to $24.4 million for the six months ended June 30, 2006 with an increase in volume from 1.0 MW for the six months ended June 30, 2005 to 5.9 MW for the six months ended June 30, 2006. Net revenues from the sale of specialty solar modules and products decreased from $2.2 million for the six months ended June 30, 2005 to $1.6 million for the six months ended June 30, 2006 with a decrease in volume from 0.4 MW to 0.3 MW for the six months ended June 30, 2006. This decrease was primarily as a result of the completion of one of our large specialty solar module product contracts in mid-2005.

The significant increase in the volume of our products sold was driven primarily by a significant increase in market demand for our standard solar modules, in particular in Germany and Spain. The average selling price of our standard solar modules rose from $3.98 per watt for the six months ended June 30, 2005 to $4.09 per watt for the six months ended June 30, 2006. The average selling price of our specialty solar modules and products decreased from $5.07 per watt for the six months ended June 30, 2005 to $4.87 per watt for the six months ended June 30, 2006, primarily due to a change in the product mix of our specialty solar modules as one of our large specialty solar module contracts ended in mid-2005 and, as a result, a larger percentage of the specialty solar modules and products that we sold in the six months ended June 30, 2006 consisted of smaller-sized modules sold to Chinese domestic customers that were less complex and commanded a lower average selling price per watt. The prices that we charge for specialty solar modules and products are not directly comparable from period to period nor between different products. See “— Product Mix and Pricing.”

Cost of Revenues. Our cost of revenues increased significantly from $3.9 million for the six months ended June 30, 2005 to $18.6 million for the six months ended June 30, 2006. The increase in our cost of revenues was due primarily to a significant increase in the quantity of solar cells needed to produce an increased output of our standard solar modules and the rising prices of silicon feedstock and solar cells arising from the industry-wide shortage of high-purity silicon. As a percentage of our total net revenues, cost of revenues increased from 56.1% for the six months ended June 30, 2005 to 71.5% for the six months ended June 30, 2006, primarily as a result of our changing product mix. The sale of specialty solar modules and products, which tend to have lower cost of revenues than standard solar modules, decreased as a percentage of our net revenues from 31.6% to 6.0% for the six months ended June 30, 2005 and 2006, respectively.

Gross Profit. As a result of the foregoing, our gross profit increased significantly from $3.1 million for the six months ended June 30, 2005 to $7.4 million for the six months ended June 30, 2006. Our gross margin decreased from 43.9% for the six months ended June 30, 2005 to 28.5% for the six months ended June 30, 2006.

Operating Expenses. Our operating expenses increased by 177.5% from $836,690 for the six months ended June 30, 2005 to $2.3 million for the six months ended June 30, 2006. The increase in our operating

expenses was due primarily to an increase in our general and administrative expenses and selling expenses. Operating expenses as a percentage of our total net revenue decreased from 12.0% for the six months ended June 30, 2005 to 8.9% for the six months ended June 30, 2006.

Selling Expenses. Our selling expenses increased significantly from $67,135 for the six months ended June 30, 2005 to $528,544 for the six months ended June 30, 2006. Selling expenses as a percentage of our total net revenues doubled from 1.0% for the six months ended June 30, 2005 to 2.0% for the six months ended June 30, 2006. The increase in our selling expenses was due primarily to (i) share-based compensation expenses that we incurred in connection with our grant of share options and restricted shares to sales and marketing personnel in the six months ended June 30, 2006, and (ii) an increase in salaries and benefits as we hired additional sales personnel to handle our increased sales volume. The increase was also due to an increase in advertising expenses as we further promoted our products, in particular in Europe, and to an increase in freight charges for samples and customs and clearance charges.

General and Administrative Expenses. Our general and administrative expenses increased by 129.7% from $761,465 for the six months ended June 30, 2005 to $1.8 million for the six months ended June 30, 2006, primarily due to (i) the share-based compensation expenses that we incurred in connection with our grant of share options and restricted shares to general and administrative employees in the six months ended June 30, 2006, and (ii) increases in salaries and benefits for our administrative and finance personnel as we hired additional personnel in connection with the growth of our business. As a percentage of our total net revenues, general and administrative expenses decreased from 10.9% for the six months ended June 30, 2005 to 6.7% for the six months ended June 30, 2006, primarily as a result of the greater economies of scale that we achieved in the six months ended June 30, 2006.

Research and Development Expenses. Our research and development expenses increased significantly from $8,090 for the six months ended June 30, 2005 to $44,440 for the six months ended June 30, 2006.

Interest Expenses. We incurred interest expenses of approximately $1.6 million for the six months ended June 30, 2006 compared to none for the six months ended June 30, 2005. The interest expenses were in connection with (i) the convertible notes that we sold to HSBC and JAFCO in November 2005 and March 2006 and which were outstanding in the six months ended June 30, 2006, (ii) the $1.3 million loan that we borrowed from ATS in September 2005 and which remains outstanding, (iii) interest payable for our short-term borrowings, and (iv) non-cash amortization of discount on debts in relation to the convertible notes issued to HSBC and JAFCO.

Loss on Change in Fair Value of Derivatives Related to Convertible Notes. We recorded a charge of $7.0 million for the six months ended June 30, 2006 compared to nil for the six months ended June 30, 2005 for the loss on change in fair value of derivatives related to convertible notes. After amending the terms of our convertible notes in March 2006, we no longer incur this charge.

Loss on Financial Instruments Related to Convertible Notes. We recorded a non-cash charge of $1.2 million for the six months ended June 30, 2006 compared to nil for the six months ended June 30, 2005. After issuing the second tranche convertible notes together with convertible notes issued pursuant to the investors’ option in March 2006, we no longer incur this charge.

Income Tax Expense. Our income tax expense was $336,315 for the six months ended June 30, 2005, as compared to a gain of $110,568 for the six months ended June 30, 2006, in part due to the tax benefit from an increase in accrued warranty costs, which were recorded as deferred tax assets under U.S. GAAP.

Net Income/ Loss. As a result of the cumulative effect of the above factors, we recorded net income of $1.9 million for the six months ended June 30, 2005, as compared to a $4.6 million net loss for the six months ended June 30, 2006.

Year Ended December 31, 2005 Compared to Year Ended December 31, 2004

Net Revenues. Our total net revenues increased significantly from $9.7 million in 2004 to $18.3 million in 2005. The increase was due primarily to a significant increase in net revenues generated from the sale of solar module products from $8.9 million in 2004 to $17.9 million in 2005. This was offset in part by a decrease in other net revenues generated from our implementation of solar power development projects from $743,601 in 2004 to $428,417 in 2005. The volume of our solar module products sold increased from 2.2 MW in 2004 to 4.1 MW in 2005. Among our solar module product categories, the increase was driven primarily by sales of our standard solar modules. Net revenues from the sale of standard solar modules increased from $6.5 million in 2004 to $13.7 million in 2005 with an increase in volume from 1.8 MW in 2004 to 3.4 MW in 2005. Net revenues from the sale of specialty solar modules and products increased to a lesser extent from $2.3 million in 2004 to $3.7 million in 2005 with an increase in volume from 0.4 MW to 0.7 MW in 2005.

The significant increase in the volume of our products sold was driven primarily by a significant increase in market demand for our standard solar modules, in particular in Germany and elsewhere in Europe. The average selling price of our standard solar modules rose from $3.62 per watt in 2004 to $3.92 per watt in 2005. The average selling price of our specialty solar modules and products decreased from $5.23 per watt in 2004 to $5.13 per watt in 2005. The decrease was primarily due to a change in our product mix from 2004 to 2005 as the orders on one of our specialty solar modules and products from 2004 ended in mid-2005. In addition, a larger percentage of the specialty solar modules and products that we sold in 2005 consisted of smaller-sized modules sold to Chinese domestic customers that were less complex and commanded a lower average selling price per watt. The prices that we charge for specialty solar modules and products are not directly comparable from period to period nor between different products. See “— Product Mix and Pricing.”

Cost of Revenues. Our cost of revenues increased significantly from $6.5 million in 2004 to $11.2 million in 2005. The increase in our cost of revenues was due primarily to a significant increase in our expenditures on silicon feedstock and solar cells. This was caused by a significant increase in the quantity of solar cells needed to produce an increased output of our standard solar modules and the rising prices of silicon feedstock and solar cells due to the industry-wide shortage of high-purity silicon. As a percentage of our total net revenues, however, cost of revenues decreased from 66.8% in 2004 to 61.2% in 2005 primarily because of the cost savings we achieved largely through our silicon reclamation program in 2005, which allowed us to purchase more lower-cost reclaimable silicon for use in our toll manufacturing arrangements with ingot, wafer and cell suppliers. The decrease was also due in part to the economies of scale achieved through an increase in our production volume.

Gross Profit. As a result of the foregoing, our gross profit increased significantly from $3.2 million in 2004 to $7.1 million in 2005. Our gross margin increased from 33.2% in 2004 to 38.8% in 2005.

Operating Expenses. Our operating expenses increased by 36.5% from $1.4 million in 2004 to $1.9 million in 2005. Operating expenses as a percentage of our total net revenue decreased from 14.2% in 2004 to 10.3% in 2005. The increase in our operating expenses was due primarily to an increase in our general and administrative expenses, offset by decreases in our selling expenses and research and development expenses.

Selling Expenses. Our selling expenses decreased by 41.4% from $268,994 in 2004 to $157,763 in 2005. Selling expenses as a percentage of our total net revenues, decreased from 2.8% in 2004 to 0.9% in 2005. The decrease in our selling expenses was due primarily to a significant decrease in sales commissions. In 2005 we negotiated a reduction of our cash sales commissions with our sales and marketing personnel. We intend to prospectively tie a portion of sales commissions related to future product sales by granting either options to purchase our common shares or by granting restricted shares. The decrease was offset in part by an increase in salaries and benefits as we hired additional sales personnel to handle our increased sales volume.

General and Administrative Expenses. Our general and administrative expenses increased by 59.7% from $1.1 million in 2004 to $1.7 million in 2005. The increase in our general and administrative expenses

was due primarily to increases in salaries and benefits for our administrative and finance personnel as we hired additional personnel in connection with the growth of our business. The increase was also due to foreign exchange losses as a result of the fluctuations of the Euro, which was the currency that most of our sales contracts were denominated in prior to mid-2005, against the U.S. dollar. However, general and administrative expenses as a percentage of our total net revenues decreased from 11.0% in 2004 to 9.3% in 2005, primarily as a result of the greater economies of scale we achieved in 2005.

Research and Development Expenses. Our research and development expenses decreased by 59.7%from $40,623 in 2004 to $16,381 in 2005.

Interest Expenses. We incurred interest expenses of approximately $239,225 in 2005 compared to none in 2004. Our interest expenses in 2005 were primarily attributable to the non-cash charges that we accrued in connection with the convertible notes that we issued to HSBC and JAFCO in November 2005 and, to a lesser extent, to interest on short-term borrowings.

Loss on Change in Fair Value of Derivatives Related to Convertible Notes. We recorded a charge of $316,000 in 2005 compared to none in 2004. The loss on change in fair value of derivatives related to convertible notes was recorded in connection with an increase in the option value of the convertible notes that we issued to HSBC and JAFCO in November 2005.

Loss on Financial Instruments Related to Convertible Notes. We recorded a non-cash charge of $263,089 in 2005 compared to none in 2004.

Income Tax Expense. Our income tax expense increased by 66.8% from $362,882 in 2004 to $605,402 in 2005, primarily because of increased profitability, offset by the tax benefit from an increase in accrued warranty costs, which were recorded as deferred tax assets under U.S. GAAP.

Net Income. As a result of the cumulative effect of the above factors, net income increased significantly from $1.5 million in 2004 to $3.8 million in 2005. Our net margin increased from 15.0% in 2004 to 20.8% in 2005.

Year Ended December 31, 2004 Compared to Year Ended December 31, 2003

Net Revenues. Our total net revenues increased significantly from $4.1 million in 2003 to $9.7 million in 2004. The increase was due primarily to a significant increase in net revenues generated from the sale of solar module products from $4.0 million in 2003 to $8.9 million in 2004. Other net revenues generated from our implementation of solar power development projects also increased significantly from $104,743 in 2003 to $743,601 in 2004 due to our achieving milestones in our “Solar Electrification for Western China” project. The volume of our solar module products sold increased from 0.7 MW in 2003 to 2.2 MW in 2004. We generated net revenues from the sale of standard solar modules of $6.5 million with a volume of 1.8 MW in 2004, although we did not begin to sell standard solar modules until the second half of 2004. The increase in the volume of our solar module products sold was offset in part by a decrease in sales of specialty solar modules and products. Net revenues from the sale of specialty solar modules and products decreased from $4.0 million in 2003 to $2.3 million in 2004 with a decrease in volume from 0.7 MW to 0.4 MW due primarily to the completion of our contract with a major customer.

We began to sell standard solar modules in the second half of 2004 to meet rising industry demand for that product and in connection with the growth of the on-grid market, particularly in Germany. The average selling price per watt of our standard solar modules was $3.62 in 2004. The average selling price of our specialty solar modules and products decreased from $5.70 per watt in 2003 to $5.23 per watt in 2004, due primarily to a change in our product mix from 2003 to 2004 as the orders on one of our specialty solar modules and products that we sold in 2003 and the first half of 2004 ended in the second half of 2004. In 2004, a larger percentage of our specialty solar modules and products consisted of smaller-sized modules to Chinese domestic customers that were less complex and commanded a lower average selling price per watt. The prices that we charge for specialty solar modules and products are not directly comparable from period to period nor between different products. See “— Product Mix and Pricing.”

Cost of Revenues. Our cost of revenues increased significantly from $2.4 million in 2003 to $6.5 million in 2004. The increase in our cost of revenues was due primarily to a significant increase in our expenditures on solar cells and other materials necessary for the production of standard solar modules. As we began selling standard solar modules in the second half of 2004, we began to purchase a greater number of solar cells to meet demand for that product. As a percentage of our total net revenues, our cost of revenues increased from 57.6% in 2003 to 66.8% in 2004. Sales of standard solar modules, which were approximately 67.0% of our net revenues in 2004 as compared to none in 2003, tend to have lower gross margins than our specialty solar modules and product. “See — Gross Profit/ Gross Margin.”

Gross Profit. As a result of the foregoing, our gross profit increased significantly from $1.7 million in 2003 to $3.2 million in 2004. Our gross margin decreased from 42.3% in 2003 to 33.2% in 2004.

Operating Expenses. Our operating expenses increased by 25.6% from $1.1 million in 2003 to $1.4 million in 2004. Operating expenses as a percentage of our total net revenues decreased from 26.7% in 2003 to 14.2% in 2004. The increase in our operating expenses was due primarily to a significant increase in selling expenses and to a lesser extent an increase in general and administrative expenses and research and development expenses.

Selling Expenses. Our selling expenses increased significantly from $38,792 in 2003 to $268,994 in 2004. Selling expenses as a percentage of our total net revenues, increased from 0.9% in 2003 to 2.8% in 2004. The increase in our selling expenses was due primarily to an increase in sales commissions paid to sales staff and salaries and benefits as we hired additional sales personnel to handle our increased sales volume and target markets in Europe for the sale of our standard solar modules.

General and Administrative Expenses. Our general and administrative expenses increased by 2.9% from $1.0 million in 2003 to $1.1 million in 2004. The increase in our general and administrative expenses was due primarily to increases in salaries and benefits for our administrative and finance personnel as we hired additional personnel in connection with the growth of our business. The increase was also due to an increase in government and administration fees. The increase was offset in part by foreign exchange gains as a result of the fluctuations of the Euro and to a decrease in provisions for bad debt as we typically require prepayments for the sale of our standard solar module products. However, general and administrative expenses as a percentage of our total net revenues, decreased from 25.3% in 2003 to 11.0% in 2004, primarily as a result of the greater economies of scale we achieved in 2004 through the mass production of our standard solar modules.

Research and Development Expenses. Our research and development expenses increased from $19,780 in 2003 to $40,623 in 2004.

Extraordinary Gain. We recorded $350,601 extraordinary gain in 2003 compared to none in 2004.

Income Tax Expense. Our income tax expense increased from $33,560 in 2003 to $362,882 in 2004, primarily because of: (i) higher taxable income; and (ii) the expiration of a two year exemption from EIT at the end of 2003 and the initiation of a 12% preferential EIT rate for CSI Solartronics beginning in 2004. See “Overview of Financial Results — Income Tax Expense.”

Minority Interest. We recorded $209,802 in 2003 for minority interests in connection with the interests in CSI Changshu that we did not hold prior to our acquisitions of such interests in December 2003, compared to none in 2004.

Net Income. As a result of the cumulative effect of the above factors, net income increased by 91.4% from $0.8 million in 2003 to $1.5 million in 2004. Our net margin decreased from 18.5% in 2003 to 15.0% in 2004.

As we have a limited operating history, most of our growth has occurred during the most recent quarters and our quarterly results have fluctuated, our operating results for any quarter are not necessarily

indicative of results of any future quarters or for a full year. See “Risk Factors — Risks Related to Our Company and Our Industry — Evaluating our business and prospects may be difficult because of our limited operating history” and “— Our quarterly results may fluctuate from period to period in the future.”

Liquidity and Capital Resources

Cash Flows and Working Capital

To date, we have financed our operations primarily through cash flows from operations, short-term borrowings, convertible note issuances, as well as equity contributions by our shareholders. As of December 31, 2005 and June 30, 2006, we had $6.3 million and $10.7 million in cash and cash equivalents, respectively, and $1.3 million and $14.3 million in outstanding short-term borrowings, respectively. Our cash and cash equivalents primarily consist of cash on hand, demand deposits and liquid investments with original maturities of three months or less that are placed with banks and other financial institutions. Our short-term borrowings outstanding as of December 31, 2005 bore an average interest rate of 7.0% and as of June 30, 2006 bore interest rates ranging from from 5.94% to 7.0%. These borrowings do not have fixed repayment schedules. We did not have any outstanding long-term borrowings as of December 31, 2004. As of December 31, 2005, we had $8.1 million of convertible notes outstanding. These convertible notes were issued in November 2005 to HSBC and JAFCO. These notes bear cash interest at the rate of 2.0% per annum, payable quarterly in arrears. In March 2006, we issued additional convertible notes in the aggregate amount of $3.65 million to HSBC and JAFCO with substantially the same terms. Therefore, as of June 30, 2006, we had $11.75 million convertible notes outstanding. All of these convertible notes were converted into our common shares in July 2006. See “Related Party Transactions — Issuance, Sale and Conversion of Convertible Notes.”

We have significant working capital commitments because our suppliers of solar cells and silicon raw materials require us to make prepayments in advance of their shipment. Our suppliers typically require us to make prepayments in cash of 20% to 30% of the purchase price and require us to pay the balance of the purchase price by letters of credit or additional cash payments prior to delivery. Due to the industry-wide shortage of high-purity silicon, working capital and access to financings to allow for the purchase of silicon feedstock are critical to growing our business. Advances to suppliers increased significantly from $370,257 as of December 31, 2004 to $4.7 million as of December 31, 2005 and further to $9.1 million as of June 30, 2006. While we also require our customers to make prepayments, there is typically a lag between the time of our prepayment for solar cells and silicon raw materials and the time that our customers make prepayments to us. Accordingly, our cash flow from operations was negative for 2005 compared to positive in 2004 and negative for the six months ended June 30, 2005 and 2006.

We expect that accounts receivable and inventories, two of the principal components of our current assets, will continue to increase as our net revenues increase. We require prepayments in cash of 20% to 30% of the purchase price from our customers, and require many of them to pay the balance of the purchase price by letters of credit prior to delivery. These prepayments are recorded as our current liabilities under advances from suppliers and customers, and amounted to $273,231 as of December 31, 2004, $2.8 million as of December 31, 2005 and $7.3 million as of June 30, 2006. Until the letters of credit are drawn in accordance with their terms, the balance purchase price is recorded as accounts receivable. Inventories have also increased significantly due to our toll manufacturing arrangements. We do not record the silicon feedstock and other silicon raw materials that we source and provide to toll manufacturers in our net revenues. We account for the silicon feedstock as consigned inventory and for payments received from our toll manufacturers as advances from suppliers and customers. Because of the prepayment and the letters of credit payment requirements that we impose on our customers, our allowance for doubtful accounts has not been significant. Allowance for doubtful accounts was $117,685 in 2004 and 2005, relating to the same customer, and nil for the six months ended June 30, 2006.

The following table sets forth a summary of our cash flows for the periods indicated:

Operating Activities

Net cash used in operating activities increased from $1.2 million for the six months ended June 30, 2005 to $10.1 million for the six months ended June 30, 2006, primarily due to significant increases in our inventories, our advances to suppliers as well as accounts receivable at the end of the six months ended June 30, 2006. The increase was also due to our net income of $1.9 million in the first half of 2005 compared to net loss of $4.6 million in the first half of 2006. Our cash outflow was partially offset by the increases in our accounts payable as well as advances from suppliers and customers. Net cash used in operating activities in 2005 was $4.7 million, compared to net cash provided by operating activities in 2004 of $439,550. The change from cash inflow to cash outflow in 2005 was mainly a result of a significant increase in the level of our inventories (particularly silicon feedstock) due to the increase in our toll manufacturing arrangements in 2005, advances to suppliers and accounts receivable at the end of 2005 compared to the end of 2004. This was partially offset by a higher net income in 2005 and a significant increase in accounts payable as at the end of 2005 compared to the end of 2004. Net cash provided by operating activities decreased from $1.8 million in 2003 to $439,550 in 2004. The decrease was due primarily to a significant increase in inventories, accounts receivable and advances to suppliers at the end of 2004 compared to the end of 2003. The decrease was also due to the minority interest that we recorded in 2003, as compared to none in 2004. The decrease was offset in part by a higher net income in 2004 and a significant increase in accounts payable, income tax payable, other tax payable and advances from suppliers at the end of 2004 compared to the end of 2003.

Investing Activities

Net cash used in investing activities increased from $58,369 for the six months ended June 30, 2005 to $1.1 million for the six months ended June 30, 2006, primarily due to a $647,431 incurrence of restricted cash attributable to issuances of bank acceptance notes payable and a significant increase in our purchase of property, plant and equipment for the expansion of our assembly lines for the increased production of our solar module products. Net cash used in investing activities increased from $252,249 in 2004 to $645,997 in 2005, primarily as a result of an increase in our purchase of property, plant and equipment for our silicon reclamation program and the expansion of our assembly lines for the production of solar module products. Net cash used in investing activities decreased from $441,499 in 2003 to $252,249 in 2004, primarily as a result of the $331,006 cash amount that we paid for the acquisition of equity interests in CSI Solartronics from our prior Chinese joint venture partners. The decrease was offset in part by a significant increase in our purchase of property, plant and equipment for the expansion of our assembly lines for the production of solar module products and as we began selling standard solar modules.

Financing Activities

Net cash provided by financing activities was $15.5 million for the six months ended June 30, 2006, as compared to nil for the six months ended June 30, 2005, primarily due to the net proceeds received from $13.0 million in short-term borrowings and a $3.65 million issuance of convertible notes to HSBC and JAFCO in March 2006, partially offset by the incurrence of issuance costs in connection with the convertible notes and this offering. Net cash provided by financing activities amounted to $9.3 million in 2005, representing the net proceeds received from a $1.3 million short-term borrowing and a $8.1 million convertible note issuance. We did not raise any funds through financing activities in 2004 or 2003.

We believe that our current cash and cash equivalents, anticipated cash flow from operations and proceeds from this offering will be sufficient to meet our anticipated cash needs, including our cash needs for working capital and capital expenditures for at least the next 12 months. We may, however, require additional cash due to changing business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If our existing cash is insufficient to meet our requirements, we may seek to sell additional equity securities, debt securities or borrow from lending institutions. We cannot assure you that financing will be available in the amounts we need or on terms acceptable to us, if at all. The sale of additional equity securities, including convertible debt securities, would dilute our shareholders. The incurrence of debt would divert cash for working capital and capital expenditures to service debt obligations and could result in operating and financial covenants that restrict our operations and our ability to pay dividends to our shareholders. If we are unable to obtain additional equity or debt financing as required, our business operations and prospects may suffer.

Capital Expenditures

We made capital expenditures of $414,918, $253,570, $560,793 and $511,853 in 2003, 2004, 2005 and for the six months ended June 30, 2006 respectively. In the past, our capital expenditures were used primarily to purchase equipment for our silicon reclamation program and for the expansion of our assembly lines for the production of solar modules. Our capital expenditures in 2006 have been and will be used primarily to purchase manufacturing equipment for the expansion of our solar module assembly lines and for the establishment of a solar cell plant.

(1)	Guaranteed by Changshu Municipal Industry State Owned Assets Operation and Investment Company and Changshu City Xinzhuang County Assets Operation and Investment Company. These guarantors, which have no other relationship with us, are state- or collectively-owned companies that seek to promote the development of and investment in the local community.

(2)	Guaranteed by Suzhou New District Economic Development Group Corporation, which has no other relationship with us. We pay a fee of 1.0% of the loan facility amount per annum for the guarantee and have pledged security interests over all of the current assets of CSI Solar Manufacturing and CSI Solartronics and 51% equity interests in these two companies held by us to secure the guarantee. Dr. Shawn Qu, our chairman and chief executive officer, has also provided a counter-guarantee for the guarantee.

(3)	CSI Solartronics entered into a maximum guarantee agreement with this commercial bank, under which CSI Solartronics agreed to provide a guarantee of up to RMB 26.4 million ($3.3 million) for short-term borrowings of CSI Solar Manufacturing incurred during a six-month period commencing from August 7, 2006.

(4)	Changshu Municipal Industry State Owned Assets Operation and Investment Company, as the guarantor, entered into a maximum guarantee agreement with this commercial bank, under which the guarantor agreed to provide a guarantee of up to RMB20.0 million ($2.5 million) for short-term borrowings of CSI Solartronics incurred during the one-year period commencing from September 7, 2006.

The loan agreements contain customary restrictive covenants, including restrictions on change of business operations, mergers, creating security interests over assets and disposal of material assets, and impose customary notice obligations upon a material negative change. If we are late in repaying principal or interest or we do not use the proceeds for working capital purposes, we will be subject to default interest rates. The loan repayments will be accelerated upon the suspension of our business operations, material negative changes to security and the occurrence of other events of default. As of the date of this prospectus, we are in compliance with the covenants in these loan agreements.

In addition, in August 2004, we entered into a revolving facility loan agreement in the amount of C$500,000 with the Royal Bank of Canada for working capital purposes. This loan facility was guaranteed by our chairman and chief executive officer, Dr. Shawn Qu. As of December 31, 2005 and June 30, 2006, we did not have any outstanding obligation under this facility.

In implementing our plans to expand our solar module assembly capacity, we registered Changshu CSI Advanced Solar Inc., or CSI Advanced, as a wholly owned subsidiary in Changshu, China in August 2006. We plan to invest $16.8 million in CSI Advanced as registered capital with cash from our operations and proceeds from this offering. If we do not invest that amount within two years of the date the business license for CSI Advanced was issued, we may apply to reduce the amount of the planned registered capital, or CSI Advanced’s business license will be revoked and we may have to reapply for the establishment of a company in Changshu. In addition, PRC rules require that we invest the first installment of registered capital within three months of the date of the business license, failing which the investment approval of the authorities will be automatically terminated. We did not make the first installment investment but have obtained from the relevant local authority after the deadline, an extension to the end of November 2006.

Off-balance Sheet Commitments and Arrangements

We have not entered into any financial guarantees or other commitments to guarantee the payment obligations of third parties. We have not entered into any derivative contracts that are indexed to our shares and classified as shareholder’s equity, or that are not reflected in our consolidated financial statements. Furthermore, we do not have any retained or contingent interest in assets transferred to an unconsolidated entity that serves as credit, liquidity or market risk support to such entity. We do not have any variable interest in any unconsolidated entity that provides financing, liquidity, market risk or credit support to us or that engages in leasing, hedging or research and development services with us.

Restricted Net Assets

Our PRC subsidiaries are required under PRC laws and regulations to make appropriations from net income as determined under accounting principles generally accepted in the PRC, or PRC GAAP, to non-distributable reserves which include a general reserve and a staff welfare and bonus reserve. The general reserve is required to be made at not less than 10% of the profit after tax as determined under PRC GAAP. The staff welfare and bonus reserve is determined by our board of directors. The general reserve is used to offset future extraordinary losses. Our PRC subsidiaries may, upon a resolution of the board of directors, convert the general reserve into capital. The staff welfare and bonus reserve is used for the collective welfare of the employees of the PRC subsidiaries. These reserves represent appropriations of the retained earnings determined under PRC law. In addition to the general reserve, our PRC subsidiaries are required to obtain approval from the local government authorities prior to distributing any registered share capital. Accordingly, both the appropriations to general reserve and the registered share capital of the our PRC subsidiaries are considered as restricted net assets. These restricted net assets amounted to $770,116, $851,516, $4.6 million and $7.8 million at December 31, 2003, 2004, 2005 and June 30, 2006, respectively.

Inflation

Since our inception, inflation in China has not materially impacted our results of operations. According to the National Bureau of Statistics of China, the change of consumer price index in China was 1.2%, 3.9% and 1.8% in 2003, 2004 and 2005, respectively.

Market Risks

Foreign Exchange Risk

Our financial statements are expressed in the U.S. dollar, which is our functional currency. Until June 2005, a major portion of our sales were denominated in Euros, with the remainder in U.S. dollars and Renminbi. The major portion of our costs and expenses is denominated in U.S. dollars. Since June 2005, substantially all of our sales have been denominated in U.S. dollars. We also incur a portion of our costs and expenses in Renminbi, primarily related to domestic sourcing of solar cells and silicon raw materials, toll manufacturing fees, labor costs and local overhead expenses. We also have loan arrangements with Chinese commercial banks that are denominated in Renminbi. Therefore, fluctuations in currency exchange rates could have an impact on our financial stability. Fluctuations in exchange rates, particularly among the U.S. dollar and Renminbi, affect our gross and net profit margins and could result in foreign exchange and operating losses. Our exposure to foreign exchange risk primarily relates to currency gains or losses resulting from timing differences between signing of sales contracts and settling of these contracts. We recorded net foreign currency loss of $8,721 in 2003, gain of $230,960 in 2004, loss of $106,059 in 2005 and loss of $76,162 for the six months ended June 30, 2006.

Interest Rate Risk

Our exposure to interest rate risk primarily relates to interest expenses incurred by our short-term and long-term borrowings, as well as interest income generated by excess cash invested in demand deposits and liquid investments with original maturities of three months or less. Such interest-earning instruments carry a degree of interest rate risk. We have not used any derivative financial instruments to manage our interest rate risk exposure. We have not been exposed nor do we anticipate being exposed to material risks due to changes in interest rates. However, our future interest expense may increase due to changes in market interest rates.

Recent Accounting Pronouncements

In November 2004, the Financial Accounting Standards Board, or FASB, issued SFAS No. 151, “Inventory Costs — an amendment of ARB No. 43, Chapter 4.” SFAS No. 151 clarifies the accounting that requires abnormal amounts of idle facility expenses, freight, handling costs, and spoilage costs to be recognized as current-period charges. It also requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS No. 151 will be effective for inventory costs incurred in fiscal period beginning on or after June 15, 2005. We do not anticipate that the adoption of this statement will have a material effect on our financial position, cash flow or results of operations.

In December 2004, the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets — an amendment of APB Opinion No. 29,” or SFAS 153, which amends Accounting Principles Board Opinion No. 29, “Accounting for Nonmonetary Transactions” to eliminate the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. SFAS 153 is effective for nonmonetary assets exchanges occurring in fiscal periods beginning after June 15, 2005. We do not anticipate that the adoption of this statement will have a material effect on our financial position, cash flow or results of operations.

In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections,” or SFAS 154, which replaces Accounting Principles Board Opinions No. 20 “Accounting Changes” and SFAS No. 3, “Reporting Accounting Changes in Interim Financial Statements — An Amendment of APB Opinion No. 28.” SFAS 154 provides guidance on the accounting for and reporting of accounting changes and error corrections. It establishes retrospective application, or the latest practicable date, as the required method for reporting a change in accounting principle and the reporting of a correction of an error. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. We do not anticipate that the adoption of this statement will have a material effect on our financial position, cash flow or results of operations.

In December 2004, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment, or SFAS 123R. SFAS 123R eliminates the alternative of applying the intrinsic value measurement provisions of APB 25 to stock compensation awards issued to employees. Rather, SFAS 123R requires enterprises to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost will be recognized over the period during which an employee is required to provide services in exchange for the award, known as the requisite service period (usually the vesting period).

In March 2005, the FASB issued FASB Interpretation No., or FIN 47, “Accounting for Conditional Assets Retirement Obligations, an interpretation of SFAS No. 143.” FIN 47 clarifies that an entity is required to recognize a liability for legal obligation to perform an asset retirement activity if the fair value can be reasonably estimated even though the timing and/or method of settlement are conditional on a future event. FIN 47 is required to be adopted for annual reporting periods ending after December 15, 2005. We do not anticipate that the adoption of this statement will have a material effect on our financial position, cash flow or results of operations.

In September 2005 the FASB approved EITF Issue 05-07, Accounting for Modifications to Conversion Options Embedded in Debt Securities and Related Issues, or EITF 05-07. EITF 05-07 requires the change in the fair value of an embedded conversion option upon modification be included in the analysis under EITF Issue 96-16, Debtor’s Accounting for a Modification or Exchange of Debt Instruments, to determine whether a modification or extinguishment has occurred and that the changes to the fair value of a conversion option affects the interest expense on the associated debt instrument following a modification. Therefore, the change in fair value of the conversion option should be recognized upon the modification as a discount or premium associated with the debt, and an increase or decrease in additional paid-in capital. EITF Issue 05-07 is effective for all debt modifications in annual or interim periods beginning after December 31, 2005. The adoption of EITF 05-07 did not have an impact on our financial position and results of operations.

In June 2006 the FASB released Interpretation No. 48, Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement No. 109, or FIN 48, which proscribes a recognition threshold and a measurement attribute for tax positions taken, or expected to be taken, in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006, with early adoption encouraged if the enterprise has not yet issued financial statements for fiscal years or interim periods in the period this Interpretation is adopted. We do not anticipate that the adoption of this statement will have a material effect on our financial position, cash flow or results of operations.

OUR BUSINESS

Overview

We design, manufacture and sell solar module products that convert sunlight into electricity for a variety of uses. We are incorporated in Canada and conduct all of our manufacturing operations in China. Our products include a range of standard solar modules built to general specifications for use in a wide range of residential, commercial and industrial solar power generation systems. We also design and produce specialty solar modules and products based on our customers’ requirements. Specialty solar modules and products consist of customized modules that our customers incorporate into their own products, such as solar-powered bus stop lighting, and complete specialty products, such as solar-powered car battery chargers. Our products are sold primarily under our own brand name and also produced on an OEM basis for our customers. We also implement solar power development projects, primarily in conjunction with government organizations to provide solar power generation in rural areas of China.

Supply chain management is critical to the success of our business, particularly during the current industry-wide shortage of high-purity silicon. We proactively manage our supply chain, which consists of silicon feedstock, ingots, wafers and solar cells, to secure a cost-effective supply of solar cells, the key component of our solar module products. We do this primarily by directly sourcing silicon feedstock, which consists of high-purity silicon and reclaimable silicon. Under toll manufacturing arrangements, we provide the silicon feedstock to manufacturers of ingots, wafers and cells, which in turn convert these silicon raw materials ultimately into the solar cells that we use for our production of solar modules. We believe we were one of the first solar module companies to process reclaimable silicon, which consists primarily of broken wafers and scrap silicon, for reuse in the solar power supply chain. Today, we believe we operate a large-scale and cost-efficient silicon reclamation program. We believe that the substantial industry and international experience of our management team has helped us foster strategic relationships with suppliers throughout the solar power industry value chain. We also take advantage of our flexible and low-cost manufacturing capability in China to lower our operating costs.

We have grown rapidly since March 2002, when we sold our first solar module products. Our net revenues increased from $4.1 million in 2003 to $18.3 million in 2005, representing a CAGR of 111.1%. Correspondingly, our net income increased from $761,245 to $3.8 million over the same period, representing a CAGR of 123.5%. Our net revenues increased from $7.0 million for the first six months ended June 30, 2005 to $26.0 million over the same period in 2006. We sold 0.7 MW, 2.2 MW and 4.1 MW of our solar module products in 2003, 2004 and 2005, respectively. We sold 1.4 MW and 6.2 MW of our solar module products for the first six months ended June 30, 2005 and 2006, respectively.

Our Industry

Solar power systems, which are made up of solar modules, related power electronics and other components, are used in residential, commercial and industrial applications in both on-grid and off-grid applications. The market for on-grid applications, where solar power is used to supplement a customer’s electricity purchased from a utility network, represents the largest and fastest growing segment of the market. Off-grid applications, where access to utility networks is not economical or physically feasible, offer additional opportunities for the use of solar power. Off-grid applications include road signs and call boxes,

communications support along remote pipelines and telecommunications lines and rural residential electricity generation applications. They also include car battery chargers, light emitting diode, or LED, lighting and power generation for a wide range of consumer applications such as radios, watches and toys. According to Solarbuzz, in 2005 on-grid applications accounted for 1,262 MW of total solar power system installations, compared to 198 MW for off-grid applications.

Although solar power technology has been used for several decades, the solar power market has grown significantly in the past several years. According to Solarbuzz, the global solar power market, as measured by annual solar power system installations, increased from 345 MW in 2001 to 1,460 MW in 2005, representing a CAGR of 43.4%. During the same period, solar power industry revenues grew from approximately $2.4 billion in 2001 to approximately $9.8 billion in 2005, representing a CAGR of 42.2%. Solarbuzz projects that solar power industry revenues and solar power system installations will reach $18.6 billion and 3,250 MW, respectively, by 2010. Worldwide installations of solar power systems are expected to grow at a CAGR of 17.4% from 2005 to 2010, driven largely by on-grid shipments, according to Solarbuzz. Growth in the near term will be constrained by the limited availability of high-purity silicon, but, according to Solarbuzz, is expected to accelerate after 2007.

Industry growth has been particularly strong in jurisdictions where governments offer incentives for solar power installation. Germany, Spain, the United States, China and Japan, among others, offer, or previously offered, substantial incentives through either direct subsidies for solar installation or feed-in tariff subsidies for the electricity delivered to the utility grid from solar power installations. Demand for solar power has also been driven by increasing prices for petroleum and increasing environmental concerns over the use of fossil fuels.

The Solar Power Industry Value Chain

There are various technologies used in the solar power industry, including crystalline silicon technology and thin film technologies, such as amorphous silicon and cadmium telluride. Our products use crystalline silicon technology, which is the technology on which approximately 94% of solar power products are based according to Solarbuzz. Crystalline silicon technology is considered to be efficient, stable and low in toxicity. At present, the efficiency of crystalline solar cells ranges from 12% to 19%, half to two-thirds the

theoretical maximum, according to Solarbuzz. Products based on alternative solar technologies such as thin film photovoltaic materials may have costs similar to, or lower than, the projected costs of products based on crystalline silicon technology. For example, solar modules produced using thin film materials, such as amorphous silicon and cadmium telluride, are generally less efficient, with conversion efficiencies ranging from 5% to 10% according to Solarbuzz, but require significantly less silicon to produce than crystalline silicon solar modules, such as our products, and are less susceptible to increases in silicon costs.

For crystalline silicon technology, the solar power industry value chain starts with the processing of quartz sand to produce metallurgical-grade silicon. This material is further purified into high-purity silicon, which along with reclaimable silicon comprises silicon feedstock. This silicon feedstock is then melted and either grown into mono-crystalline ingots or cast into multi-crystalline ingots. These silicon ingots are then cut, shaped and sliced into wafers, which are manufactured into solar cells. The solar cells are interconnected to form solar modules, which, together with system components, are distributed by wholesalers and resellers ultimately for on-grid and off-grid systems. Solar modules can also be integrated into other products to power a variety of industrial and consumer applications.

Key Growth Drivers

We believe the following factors have driven and will continue to drive growth in the solar power industry:

Government Incentives for Solar Power and Other Renewable Energy Sources

Increasing environmental concerns and climate change risks associated with fossil fuel-based power generation are creating political momentum and pressure to implement greenhouse gas reduction strategies. Many countries have agreed to reduce emissions of carbon dioxide and other gases through international treaties such as the Kyoto Protocol. In addition, national and regional air pollution regulations also restrict the release of carbon dioxide and other gases. Solar power and other renewable sources, such as fuel cells, wind power and hydro-electric power, help address these environmental concerns.

Governments around the world have used different policy initiatives to accelerate the development and adoption of solar power and other renewable energy sources. Renewable energy policies are in place in the European Union, certain countries in Asia, and many of the states in Australia and the United States. Examples of customer-focused financial incentives include capital cost rebates, feed-in tariffs, tax credits and net metering. Capital cost rebates provide money to customers based on the size of a customer’s solar power system. Feed-in tariffs require utilities to pay customers for solar power system generation based on kilowatt-hours produced, at a rate generally guaranteed for a period of time. Under net metering, power generated by the solar power system in excess of a consumer’s power consumption will spin the existing home or business electricity meter backwards by such excess amount, effectively reducing the customers’ electricity bill.

Fossil Fuel Supply Constraints and Desire for Energy Security

Worldwide demand for electricity is expected to increase from 14.8 trillion kilowatt hours in 2003 to 30.1 trillion kilowatt hours by 2030, according to the United States Department of Energy’s International Energy Outlook. The International Energy Agency, or IEA, estimates that approximately 80% of the world’s electricity is generated from fossil fuels such as coal, oil and natural gas. Limited fossil fuel supply and escalating electricity consumption are driving up wholesale electricity prices, resulting in higher electricity costs for consumers and highlighting the need to develop alternative technologies for reliable and sustainable electricity generation.

Furthermore, governments are trying to reduce their dependence on foreign sources of energy because of the potential political and economic instability in the major oil and gas producing regions of the world. In 2003, over 60.0% of the energy used in Germany and over 80.0% of the energy used in Italy, Spain, Japan and Korea, was imported, according to the IEA. That figure was 29.0% for the United States. Expanding the domestic portion, and particularly the renewable resources portion of the overall electricity generation portfolio, is a key element of many governments’ strategies to increase energy security.

Growing Awareness of the Advantages of Solar Power

Solar power has several advantages over both conventional and other forms of renewable energy:


	•	Peak Energy Generation Advantage. Solar power is well-suited to match peak energy needs as maximum sunlight hours generally correspond to peak demand periods when electricity prices are at their highest, as compared to other renewable resources that generally do not align power generation with peak demand periods.

	•	Fuel Risk Advantage. Unlike fossil and nuclear fuels, solar power has no fuel price volatility or delivery risk. Although the amount and timing of sunlight vary over a day, season and year, a properly sized, configured and designed system can be highly reliable while providing a long-term, fixed-price supply of electricity.

	•	Modularity. Solar power products can be deployed in many different sizes and configurations to meet the specific needs of the customer.

	•	Reliability. With no moving parts or regular required maintenance, solar power systems are among the most reliable forms of electricity generation. Accelerated aging tests have shown that solar modules can operate for 30 years or more without the need for major maintenance other than the occasional cleaning of the solar module surface.

	•	Environmental Advantage. Solar power is one of the cleanest electric generation resources, capable of generating electricity without air or water emissions, noise, vibration, habitat impact or waste generation.

Advances in Technologies Making Solar Power More Cost-Efficient

Recent advancements in technology are making it more cost-effective to use solar power in off-grid products. For example, the brightness of LEDs has increased significantly in recent years while the voltage required to power, and the cost to produce, LEDs has significantly decreased. This has allowed for the cost-effective combination of low voltage LEDs with re-chargeable solar-powered battery systems. The synergies between LED lighting and solar power are resulting in new product applications such as LED lighting for roadway, railway, marine, transit, aviation and other outdoor applications. Off-grid products have also evolved to include solar-powered bus stop signs and solar-powered oil and gas well monitoring equipments.

Similarly, technological advances in consumer electronics products, such as the increased use and decreasing costs of flash memory and other low-power storage devices, have reduced the amount of power required to operate handheld and other small devices. Consumer solar power applications have expanded beyond traditional simple solar-powered calculators, radios, watches and toys to more sophisticated products such as mobile phones and laptops.

Large Market Among Underserved Populations in Rural Areas of Developing Countries with Little or No Access to Electricity

We believe solar power is also gaining importance as a source of off-grid electricity for homes and small businesses in rural areas of developing countries with little or no grid infrastructure. According to the United Nations Commission on Sustainable Development, there are approximately 1.6 billion people in the world today without any source of electrical power. Such populations generally have modest electrical needs that do not justify the construction of power plants or the installation of electric grid extensions, and solar power systems have been or are being placed in off-grid communities in various countries in Asia, including China and India, Latin America and Africa.

While the application of solar power for rural electrification has been possible for years, we believe interest by private companies and government agencies in the use of solar power systems to provide off-grid electricity to underprovided areas is creating additional markets and distribution channels for solar power products in developing countries. Historically, this effort was primarily financed by international development agencies and environment protection funds, for example the World Bank, the United Nations, the Global Environment Fund and the Canadian International Development Agency. While these agencies and funds remain important sources of support for the solar power development projects in developing countries, we believe self-sustainable markets are emerging in countries, such as China, where economic development has increased consumer purchasing power and the market for off-grid solar power systems and products.

Challenges Facing the Solar Power Industry

The solar power industry faces the following key challenges:


	•	Shortages and Costs of High-purity Silicon. There is currently an industry-wide shortage of high-purity silicon, an essential raw material in the solar power supply chain. Given the demand and supply imbalance, supply chain management is a critical element for the continued growth of the solar power industry and for controlling silicon raw material and solar cell supply and costs.

	•	High Cost to Customers. The current cost to implement and operate a solar power system may be economically unattractive to consumers compared to the cost of retail electricity from a utility network. While government programs and consumer preference have accelerated the use of solar power for on-grid applications, product costs remain one of the impediments to growth. To provide an economically attractive alternative to conventional electricity network power, the solar power industry must continually reduce manufacturing and installation costs and find ways to make the use of solar power cost-efficient over time without government subsidies.

	•	Broadening Solar Power Usage in Off-Grid Applications. The recent growth of the solar power market has been limited primarily to the on-grid market. Advances in solar power technologies and other consumer electronics technologies that result in the expansion of off-grid applications will be important to promoting market awareness and acceptance of the everyday usefulness of solar power in consumer products. Without increased market awareness and acceptance, sales to end-users may continue to consist substantially of standard solar modules, which are becoming increasingly commoditized, and the market for specialty solar modules and products, which typically command higher margins, may not expand.

Our Competitive Strengths

We believe that the following competitive strengths enable us to compete effectively and to capitalize on the rapid growth of the global solar power market:

Our ability to manage our supply chain allows us to secure a cost-effective supply of solar cells

We proactively manage our supply chain to secure a cost-effective supply of solar cells. This has allowed us to mitigate the effects of industry-wide shortages of high-purity silicon, while reducing margin pressure. Our proactive management of the supply chain has two major components:


	•	Sourcing of silicon raw materials and toll manufacturing arrangements. We maintain strong relationships with both international and domestic suppliers of silicon raw materials. We believe our close relationships with local silicon raw materials suppliers provide us with various advantages including the ability to lock-in supplies of raw materials, quicker time-to-market of our products due to faster access to silicon raw materials and lower shipping costs because of the closer proximity to our facilities. We have entered into a five-year supply agreement with Luoyang Zhong Gui, a high-purity silicon supplier in China, which provides us a specified minimum level of high-purity silicon. We have also entered into a 10-year supply agreement with Kunical International in the U.S., which provides us specified minimum levels of reclaimable silicon and other silicon raw materials and grants us priority over any of Kunical’s excess monthly silicon feedstock supply. We also have entered into a four-year supply agreement with LDK, a silicon wafer supplier in China, which provides us with a specified level of silicon wafers. We have also entered into a 27-month agreement with Swiss Wafers for specified quantities of solar cells and solar wafers. We believe these silicon raw materials agreements will enable us to secure solar cells sufficient for a major portion of our estimated 2006 production output and a portion of our estimated 2007 production output.

We use these silicon raw materials to enter into toll manufacturing arrangements with key suppliers. Our toll manufacturers of solar wafers include LDK in China, Green Energy Technology Inc. in Taiwan, Swiss Wafers AG in Switzerland and Deutsche Solar, a subsidiary of SolarWorld AG in Germany. For solar cells, our toll manufacturers are Motech Industries Inc. and DelSolar Co., Ltd. in Taiwan, and SolarWorld AG.


	•	Silicon reclamation program. We believe that we were one of the first solar module companies to employ silicon reclaiming techniques to process reclaimable silicon for the sourcing of solar cells. Our management team also has strong experience in the silicon industry, including direct experience in silicon reclamation, and we intend to continue expanding our management capabilities in silicon reclamation. We believe that this early-mover advantage and management experience has allowed us to build a large-scale and cost-efficient silicon reclamation program. Our reclamation program, coupled with our toll manufacturing arrangements, gives us a cost-effective supply of solar cells, which allows us to lower our cost of revenues and increase gross margins for our solar module sales. We began our silicon reclamation program in 2005, which primarily drove the increase in our gross margins from 33.2% in 2004 to 38.8% in 2005 and in our net margins from 15.0% in 2004 to 20.8% in 2005.

Significant experience in the development and manufacture of high-margin specialty solar modules and products

We entered the solar module business in March 2002 by developing and manufacturing specialty solar modules and products. These products generally generate higher margins compared with those generated by our standard solar modules, primarily because of the higher average selling price that we are able to charge for the greater complexity of design. We believe this will continue in the near future. Our portfolio of specialty solar modules and products includes customized solar modules for Carmanah Technologies Corp., or Carmanah Technologies, used to power their lighting products for London bus stops, and complete specialty

products such as car battery chargers for Volkswagen and Audi. We believe our extensive experience in this business, coupled with our strength in product development, provides us with various competitive advantages. This includes quicker time-to-market, which we believe is a critical factor for succeeding in this rapidly evolving market. Expansion of our specialty solar modules and products business is expected to continue to be a longer-term driver of our margins in the future.

Flexible and low-cost manufacturing capability

We manufacture all of our products at our facilities in China. We believe our access to low-cost, skilled labor and our semi-automated manufacturing model provide us with competitive advantages by minimizing our operating costs, increasing our flexibility to meet demand and reducing our capital expenditure. Furthermore, costs associated with land, production equipment, facilities and utilities tend to be lower in China than in developed countries. One of our manufacturing facilities is situated in the export processing zone of Suzhou, China, where the raw materials used for the manufacture of our products that we export are not subject to import VAT and customs duties.

We have designed our manufacturing processes to include a mix of manual and automated production methods that reduce our capital investment and allow us to modify our production output in a timely and cost-effective manner. We believe that our semi-automated manufacturing model provides greater flexibility and is less costly than the fully automated processes often utilized in developed countries. We have also been able to reduce our capital expenditure by procuring in most instances locally designed and manufactured equipment as an alternative to more costly imported machinery.

Experienced senior management team with significant industry expertise and international background

We have an experienced senior management team that has successfully led our operations and increased our revenues and profits through rapid organic growth. Our team has significant international and domestic experience both in the solar power and semiconductor industries, which we believe gives us a deep understanding of the needs and preferences of international and domestic customers and suppliers. Dr. Shawn Qu, our founder, chairman and chief executive officer, has been instrumental in helping us achieve our rapid growth. He has over ten years of experience in the solar power industry across North America, Europe and Asia. Prior to founding our company, Dr. Qu held various managerial positions with leading energy companies such as Photowatt International S.A., or Photowatt, and ATS and also worked at Ontario Power Generation Corp. While at Photowatt, and its parent company ATS, he developed extensive experience managing silicon feedstock supply sourcing. Bencheng Li, the general manager of CSI Luoyang, has nearly 35 years of direct silicon manufacturing experience in China. His experience includes three years as chairman of Luoyang Silicon Crystal Corp, which is the parent company of Luoyang Zhong Gui, and eight years as the general manager of E-Mei Semiconductor Factory. Luoyang Zhong Gui and E-Mei Semiconductor Factory are two of our suppliers of high-purity silicon. Our vice president of international sales and marketing, Gregory Spanoudakis, has over 17 years of international experience in the semiconductor and solar power industries. Robert Patterson, our vice president of corporate and product development and general manager of Canadian operations, has over 25 years of experience working at technology companies with senior roles ranging from procurement to business development, including eight years of solar power industry experience.

We believe that the depth and breadth of our international experience, coupled with our extensive China experience, provide us with significant competitive advantages over other companies in the solar power industry.

Our Strategies

Our objective is to be a global leader in the development and manufacture of solar module products. We intend to implement the following strategies, which we have developed based on our experience, to anticipate changes in the industry:

Pursue a balanced and diversified solar cell supply channel mix

To improve the stability of our supply of solar cells, which we believe is critical to the continued success of our business, we intend to pursue a diversified supply channel strategy. As we grow our business, we believe having multiple sources of solar cells will allow us to successfully adapt to future changes in supply of and demand for solar cells. Our diversified supply strategy will consist of:


	•	Long-term cell supply contracts. We are presently in discussions with cell suppliers to secure long-term supply contracts with prepayments. We intend to source a portion of our solar cell requirements through long-term contracts in order to limit our risk from any future price increases and supply shortages.

	•	Toll manufacturing arrangements. Our toll manufacturing arrangements have allowed us to take advantage of excess wafer and cell manufacturing capacity in the industry to secure solar wafers and cells at reasonable cost by sourcing our own silicon raw materials. As the supply of high-purity silicon becomes more readily available in the future, toll manufacturing arrangements may not be available to us at higher or similar volumes. However, we believe that toll manufacturing arrangements will continue to be an important component of the solar power supply chain, in particular through the processing and use of reclaimable silicon which will maintain at a discount price compared to the cost of high-purity silicon. As such, we intend to continue to utilize toll manufacturing arrangements so long as it remains a cost-effective means of managing our solar cell supply.

	•	In-house cell manufacturing. We plan to complete our first solar cell production line in the first quarter of 2007 with commercial production targeted for the second quarter of 2007. We have completed a feasibility evaluation, have begun planning for a new solar cell plant in Suzhou and have purchased all of the key manufacturing equipment for our first solar cell line. We apply stringent criteria in selecting our vendors, including the requirement that they demonstrate at least two successful implementations of the same equipment for well-known solar cell manufacturers in Asia. After we successfully implement our first solar cell line, we plan to expand our capacity and currently intend to operate four solar cell manufacturing lines at our new solar cell plant by December 2007. Manufacturing solar cells will help us to reduce our reliance on third-party cell suppliers and improve the stability of our solar cell supply. In-house manufacturing will also give us the opportunity to reduce our costs and production lead-times. Additionally, in-house cell manufacturing will enable us to provide our OEM customers with “one-stop shop” manufacturing capability.

Continue to proactively manage silicon raw material supply.

To ensure that we have adequate and reliable supply of silicon raw materials to support toll manufacturing arrangements and in-house cell manufacturing, we believe that it is critical for us to continue to proactively source silicon feedstock, particularly during this period of industry-wide shortage. We intend to do this by focusing on the following areas:


	•	Securing long term silicon raw materials contracts. We intend to continue to engage in long-term silicon raw materials supply contracts with leading international and domestic suppliers. Presently, we have ten-year and five-year supply agreements with Kunical International and Luoyang Zhong Gui, respectively, for specified quantities of silicon feedstock. We also have a four-year agreement with LDK Solar Hi-Tech Co., Ltd. for specified quantities of solar wafers. We also have a 27-month agreement with Swiss Wafers


		for specified quantities of solar cells and solar wafers. We plan to further expand our existing relationships with these suppliers while simultaneously exploring opportunities to engage in additional long-term supply relationships with other silicon raw materials suppliers.

	•	Diversify silicon supply sources. As our business expands, we intend to develop a diversified supply of silicon raw materials from a network of suppliers. We will seek to limit our dependence on any single supplier or single raw material component by sourcing high-purity silicon, reclaimed silicon, ingots, wafers and cells from various companies. We will also seek to vary the length and terms of our agreements with our suppliers to minimize negative exposure to changes in material prices.

	•	Further develop and leverage our silicon reclamation program. Our silicon reclamation program has been a major provider of our silicon feedstock requirements and we plan to continue to expand and leverage this program so long as it remains cost effective to do so. In particular, we will use new technologies to convert multiple forms of reclaimable silicon material for processing through our toll manufacturing arrangements and to improve the yield of our reclaiming processes.

Further diversify our geographic presence, customer base and product mix

In order to continue to grow our sales of standard solar modules and to reduce our exposure to any particular market segment, we intend to broaden our geographic presence, customer base and product mix. While Germany is expected to continue to be our largest market, we plan to expand our business in established solar markets such as Japan and emerging solar markets such as Spain, the United States and China. We plan to expand into the U.S. market in anticipation of the expansion of the solar power market in the near term due to recent government incentives in key states such as California. See “— Markets and Customers.” We plan to expand our sales network by establishing sales offices in Europe and the U.S. dedicated to regional sales. We will also attempt to increase our sales in China where we expect the solar power market to grow rapidly in response to recent legislation and policies encouraging the use of alternative and renewable energy sources. We believe that our significant management expertise, in-depth knowledge of the local market and ability to use our domestic strategic alliances will enable us to benefit from the anticipated growth in China.

We will also continue to diversify our customer base and further increase sales of specialty solar modules and products. For our customized modules, we will continue to focus on the automotive industry and identify key market segments with significant potential growth, such as the LED lighting and telecommunications industries. We also plan to substantially increase sales of complete specialty products. We intend to achieve this by entering into cooperative agreements with major international companies. For example, we recently signed a non-binding letter of agreement with Carmanah Technologies, a leading producer of solar LED products, to cooperate in the development of a wide range of solar powered LED specialty products. This will allow us to broaden our product range rapidly while leveraging the sales capabilities of our customers.

Enhance innovation and efficiency through R&D

Our senior management, led by Dr. Qu, our founder, chairman and chief executive officer, Mr. Genmao Chen, our director of research and development, Dr. Lingjun Zhang, our technical director, and Mr. Chengbai Zhou, our chief engineer for solar modules, all have extensive experience in the solar power industry. We plan to devote more resources to research and development to enhance our product development capability for both standard modules and specialty solar modules and products. In particular, by improving our product development capabilities for specialty solar modules and products, we believe that we will be well-positioned for the expected growth in this area of the solar power market. We will also focus our research and development efforts on improving our manufacturing processes and supply chain management. While our current semi-automated manufacturing model requires low capital expenditure and allows for flexibility in our production processes, we will continually upgrade our manufacturing processes to enhance

our operating and cost efficiency. We will continue to devote efforts to ensure that our products comply with the European Union’s Restriction of Hazardous Substances Directive, which took effect in July 2006, by reducing the amount of lead and other restricted substances used in our solar module products. We also plan to dedicate more resources towards using new technologies in our silicon reclamation program. As we expand into solar cell manufacturing, we plan to continually invest in the development of process technologies to maximize the conversion efficiencies of our solar cells.

Build a leading global brand

We believe establishing strong brand-name recognition is important to reach our potential customers, both at the distributor and end-user level, and to expand our sales. In addition to our plans to expand our sales force, we intend to undertake a long term marketing program with both near-term and longer-term focuses to increase the recognition and value of the CSI brand. In the near term, we intend to focus our efforts on expanding our presence throughout the solar power supply and product chain to strengthen our customer and supplier relationships and to enhance our competitive position in the solar power industry. Over the longer term, we intend to extend our marketing efforts to end-users to generate greater consumer recognition of and demand for our products. We intend to position ourselves as an innovative provider of high performance and superior quality solar modules, with a cost-efficient manufacturing base, strong technical resources and an emphasis on strict quality control.

Our Products

We currently design, develop, manufacture and sell solar module products, which consist of standard solar modules and specialty solar modules and products.

Standard Solar Modules

Our standard solar modules are an array of interconnected solar cells encased in a weatherproof frame. We produce a wide variety of standard solar modules, currently ranging from 0.2 W to 300 W in power and using multi-crystalline and mono-crystalline solar cells. These products are built to general specifications for a wide range of residential, commercial and industrial solar power generation systems. Our standard solar modules are designed to be durable under harsh weather conditions and easy to transport and install. We primarily sell our standard solar modules under our own “CSI” brand and also on an OEM basis branded with our customers’ names.

Specialty Solar Modules and Products

We collaborate with our customers to design and manufacture specialty solar modules and products based on our customers’ specifications and requirements. Our specialty solar modules and products consist of:


	•	customized solar modules; and

	•	complete specialty products.

Our customized solar modules are solar modules that we design and manufacture for customers who incorporate our customized solar modules as a component of their own products. For example, we manufacture a customized array of six solar modules assembled onto a curved canopy for a customer who incorporates it into its bus stop shelter products. We design and manufacture our complete specialty products, which combine our solar modules with various electronic components that we purchase from third party suppliers. Presently, this has consisted primarily of car battery chargers for automotive customers.

Our specialty solar modules and products have been used primarily in the automotive sector. We focus on this and other industries, such as the LED lighting and telecommunications sectors, that have off-grid applications that can be powered by solar power. In the future, we intend to increasingly focus on the LED lighting industry. As LED technology advancements continue to create higher quality lighting with less power at increasingly economical prices, we believe that solar power will become a major power source in the LED lighting industry. In addition to specialty solar modules and products used in bus stop signs and our car

battery chargers, we have also produced security sensors, signaling systems and mobile phone chargers in the past. We will continue to work closely with our customers to design and develop specialty solar modules and products that meet their specific requirements. We expect sales of these products, which typically have higher margins than our standard solar modules, to increase significantly as we go forward.

Solar Power Development Projects

We also implement solar power development projects, primarily in conjunction with government organizations, to provide solar power generation in rural areas of China. In conjunction with the Canadian International Development Agency, or CIDA, we implemented a C$1.8 million “Solar Electrification for Western China” project between 2002 and June 2005. As part of this project, we installed many demonstration projects and conducted three solar power forums in Beijing, Xining and Suzhou. We also have two CIDA projects in progress: (i) a C$301,000 project to further promote solar power manufacturing in China, which we were awarded in August 2005, and (ii) a C$125,000 project to explore the feasibility of solar power plants of 1 MW or greater in China, which we were awarded in January 2006. In connection with the latter project, we are in discussions with several potential partners to develop a large-scale solar power plant in Suzhou, Jiangsu province.

To date, our solar power development projects have consisted of government-related assistance packages. Going forward, we will continue to secure and implement large-scale solar power development projects in conjunction with CIDA, the World Bank, the Asian Development Bank, and other organizations, and we will explore more commercial transactions, which are becoming more prevalent.

Supply Chain Management

Our business depends on our ability to obtain solar cells. There is presently a shortage of solar cells as a result of a shortage of high-purity silicon due to the rapid growth of and demand for solar power. Beginning in early 2005, we began managing our supply chain to secure a reliable and cost-effective supply of solar cells. This has allowed us to mitigate the effects of the industry-wide shortage of high-purity silicon, while reducing margin pressure. We secure our supply of solar cells primarily through our sourcing of silicon raw materials and toll manufacturing arrangements with suppliers of ingots, wafers and cells and through the direct purchase of cells. We minimize costs and reduce margin pressure primarily through our silicon reclamation program.

The following chart illustrates our management of the solar power supply chain:

Silicon Raw Materials

Silicon feedstock, which consists of high-purity silicon and reclaimable silicon, is the building block of the entire solar power supply chain. The major portion of the silicon feedstock that we source is reclaimable silicon.

We have entered into a five-year supply agreement with Luoyang Zhong Gui in China from 2006 to 2010. This agreement provides us specified minimum levels of high-purity silicon. We have entered into a 10-year supply agreement with Kunical International from 2006 to 2015. This agreement provides us specified minimum levels of reclaimable silicon and other silicon raw materials and grants us priority over any of Kunical International’s excess monthly silicon feedstock supply. We also have a four-year agreement with LDK from 2007 to 2010 for specified quantities of solar wafers. We also have a 27-month agreement with Swiss Wafers for specified quantities of solar cells and solar wafers.

We believe these silicon raw materials agreements will, through toll manufacturing arrangements, enable us to secure solar cells sufficient for a major portion of our estimated 2006 production output and a portion of our estimated 2007 production output. In anticipation of increased demand for solar power products, we are currently in discussions with other China-based suppliers to secure additional silicon feedstock supply. We recently incorporated CSI Luoyang to give us better access to major silicon feedstock suppliers located in Luoyang.

Silicon Reclamation Program

We believe that we were one of the first solar module companies to process reclaimable silicon to ultimately produce solar cells. We believe that this early-mover advantage has allowed us to build one of the largest and most cost-efficient silicon reclamation programs in the world today. We recycle the reclaimable silicon that we source and process it through our reclaiming facilities for reuse in the solar supply chain. Our processes recycle silicon from pot scraps, broken or unused silicon wafers, and the top and tail discarded portions of silicon ingots. Our factories in Suzhou and Changshu include reclamation workshops where our employees sort the reclaimable silicon into reprocessing categories. We believe that our access to relatively inexpensive labor in China for this process that involves a substantial amount of labor gives us a significant competitive advantage compared to international solar module manufacturers.

Our silicon reclamation program, coupled with our toll manufacturing arrangements, gives us a cost-effective supply of solar cells, which allows us to lower the cost of revenue and increase the gross margins for our solar module sales. We began our silicon reclamation program in 2005, which primarily drove the increase in our gross margins from 33.2% in 2004 to 38.8% in 2005 and in our net margins from 15.0% in 2004 to 20.8% in 2005. We are continually researching ways to improve our yields in converting reclaimable silicon and to process other types of scrap silicon.

Toll Manufacturing Arrangements

We primarily engage in toll manufacturing arrangements to source solar cells. Manufacturers of ingots, wafers and cells are facing over-capacity due to shortages of high-purity silicon and are looking for ways to obtain silicon feedstock. Through our toll manufacturing arrangements, we provide the silicon feedstock in return for ingots, wafers and cells.

Solar Wafers. Our key suppliers of solar wafers through these toll manufacturing arrangements include LDK in China, Green Energy Technology Inc., Swiss Wafers AG and Deutsche Solar, a subsidiary of SolarWorld AG.

Solar Cells. Our key suppliers of solar cells include Motech Industries Inc., Del Solar Co., Ltd., and SolarWorld AG.

Direct Solar Cell Purchasing and Expansion into Solar Cell Manufacturing

In addition to toll manufacturing arrangements that we have with our solar cell suppliers, we directly purchase or have purchased solar cells from some of the above-listed solar cell suppliers and Q-Cells AG and Sharp Solar.

We intend to continue our toll manufacturing arrangements for our supply of solar cells. As we grow our business, we will seek to diversify our cell supply channel mix to ensure flexibility in adapting to future changes in the supply of, and demand for, solar cells. Additionally, we have completed a feasibility evaluation for a new solar cell plant in Suzhou. We plan to complete our first solar cell production line in the first quarter of 2007 with commercial production targeted for the second quarter of 2007. We apply stringent criteria in selecting our vendors, including the requirement that they demonstrate at least two successful implementations of the same equipment for well-known solar cell manufacturers in Asia.

Manufacturing

We assemble our solar modules by interconnecting multiple solar cells through taping and stringing into a desired electrical configuration. The interconnected cells are laid out, laminated in a vacuum, cured by heating and then packaged in a protective light-weight anodized aluminum frame. Our solar modules are sealed and weatherproofed and are able to withstand high levels of ultraviolet radiation, moisture and extreme temperatures.

The diagram below illustrates our solar module manufacturing process:


(1)	Laser cutting is only necessary for smaller-sized modules.

We work closely with our customers during the design and manufacture of our specialty solar modules and products. For our customized modules, we collaborate with the customer to make certain that our product is compatible for incorporation into that customer’s product. For our complete specialty products, we work with the customer and typically provide sample products to the customer for testing before the product is manufactured on a larger scale.

We selectively use automation to enhance the quality and consistency of our finished products and to improve efficiency in our manufacturing processes. Key equipment in our manufacturing process includes automatic laminators, simulators and solar cell testers. The current design of our assembly lines gives us flexibility to adjust the ratio of manufacturing equipment to skilled labor for quality and efficiency control. We use manufacturing equipment purchased primarily from Chinese solar power equipment suppliers. The location of our manufacturing operations in China gives us the advantage of proximity to these Chinese manufacturers, who typically sell solar power manufacturing equipment at more competitive prices compared to similar machinery offered by international solar power equipment manufacturers. We source critical testing equipment from international manufacturers. The manufacturing of solar module products remains a labor intensive process, and we leverage China’s competitive labor costs by using labor in our manufacturing process when it proves to be more efficient and cost-effective than using equipment.

Since we began selling our solar module products in March 2002, we have increased our annual production capacity from 2 MW to 35.5 MW as of April 2006. By the end of 2007, we aim to have a production capacity of 100 MW. The nature of our flexible manufacturing process allows us to increase capacity at low cost within a short period of time to ramp up production for increased demand for standard solar modules or for new solar module products as necessary. We may not, however, use our production facilities to full capacity. Overall production output depends in part on the product mix and sizes of the solar modules produced by each laminator and is affected by the timing of customer orders and requested completion dates. Our production output is also constrained by the availability of solar cells and silicon raw materials and demand for our solar module products. Although there is a gap between our production capacity and production output, it is important for manufacturers of solar module products to maintain additional production capacity to handle surges in customer demand and quick changes in the product mix and timing of completion demanded by customers. Due to the relatively inexpensive cost of solar module manufacturing equipment, it is generally cost-efficient to maintain additional production capacity.

Our manufacturing facilities can be easily reset, allowing us to quickly ramp up production for increased orders or new solar module products as necessary. We currently operate our manufacturing lines in two factories in China and typically operate these lines 16 hours a day by rotating shifts of employees to operate the lines. We currently produce a higher volume of standard solar modules in our factory located in Suzhou and manufacture most of our specialty solar modules and products, which tend to be lower volume, at our Changshu facilities. Our employees are trained to work on different types of solar module products. This gives us the flexibility to quickly increase our manufacturing capacity and lines with additional employees in order to meet increases in demand.

Quality Control and Certifications

Our quality control was set up according to the quality system requirements of ISO 9001:2000 and ISO:TS 16949 standards. The latter originated from QS 9000 and VDA quality systems and is now the world-wide quality system standard for the automotive industry. Our quality systems are reviewed and certified by TUV Rheinland Group, a leading international service company that documents the safety and quality of products, systems and services. Our quality control focuses on incoming inspection through which we ensure the quality of the components and raw materials that we source from third parties and includes the use of simulators and solar cell testers. We focus on in-process quality control by examining our manufacturing processes and on output quality control by inspecting finished products and conducting reliability and other tests.

We have obtained IEC 61215 and TUV Class II safety European standards for sales in Europe. We are in the process of obtaining ETL/UL certification in the United States and certifications in Canada for sales of

standard solar modules to enhance our sales capability in North America. We recently received confirmation that our solar modules comply with the requirements of CAN ORD-UL 1703 and UL 1703, and we expect to receive full certification for standard solar module sales in North America in 2006.

Markets and Customers

We currently sell our standard solar modules primarily to distributors and system integrators. Our distributor customers include companies that are exclusive solar power distributors, engineering and design firms that include our standard solar modules in their system installations. Our system integrator customers typically design and sell complete, integrated systems that include our standard solar modules along with other system components. We sell our specialty solar modules and products to various manufacturers who either integrate these products into their own products or sell and market them as part of their product portfolio. In 2005, approximately 80% of our solar module product net revenues consisted of standard solar module sales. The remaining approximately 20% were from sales of specialty solar modules and products. Our standard solar module customers include leading solar power distributors and system integrators such as Bihler, Iliotec and Maass. Our specialty solar modules and products customers include automotive customers such as Audi for whom we make car battery chargers, and various manufacturers, such as Carmanah Technologies, who incorporate our customized modules in their bus stop, road lighting and marine lighting products.

A small number of customers have historically accounted for a majority of our net revenues. For the year ended December 31, 2005, our top five customers collectively accounted for approximately 68.2% of our net revenues. Bihler and Sonn-en contributed 36.8% and 14.2%, respectively, of our net revenues for the same time period. For the six months ended June 30, 2006, our top five customers collectively accounted for approximately 91.2% of our net revenues, and Iliotec, Schuco, Pevafersa, and Bihler contributed 36.0%, 18.2%, 17.3% and 11.2%, respectively, of our net revenues for the same time period.

The following table sets forth certain information relating to our total net revenues derived from our customers categorized by their geographic location for the periods indicated:

(1)	Less than a thousand.

As we expand our manufacturing capacity and enhance our brand name, we anticipate developing additional customer relationships in other markets and geographic regions to decrease our market concentration and dependence. In 2006 and in the near future, we have aimed, and will continue to aim, to increase our sales to customers located in several markets such as Germany, Spain, China, the United States, Canada and Japan. These solar power markets have been significantly influenced by past and current government subsidies and incentives, or, in the case of Canada, by intended future government subsidies and incentives. While we expect to expand our markets, we expect that Germany will continue to remain our major market in the near future.


	•	Germany. The renewable energy laws in Germany require electricity transmission grid operators to connect various renewable energy sources to their electricity transmission grids and to purchase all electricity generated by such sources at guaranteed feed-in tariffs. Additional regulatory support measures include investment cost subsidies, low-interest loans and tax relief to end users of renewable energy. Germany’s renewable energy policy has had a strong solar power focus, which contributed to Germany surpassing Japan as the leading solar power market in terms of annual megawatt additions in 2004. According to Solarbuzz, Germany grew 53% to 837 MW or 57% of the world’s total solar power production in 2005. Germany’s feed-in tariff remains one of the highest in the world. We primarily sell rooftop end-market applications of sizes less than 100 KwH. According to Solarbuzz, the feed-in tariffs for rooftop applications less than 30 KwH and between 30 KwH and 100 KwH was €0.5453 and €0.5187 per KwH, respectively, in 2005. Our major customers located in Germany are Bihler, Iliotec and Maass.

	•	Spain. In Spain, the incentive regime includes a national net metering program and favorable interest loans, and the actual feed-in tariff for solar power energy is fully guaranteed for 25 years and guaranteed at 80% subsequently. According to Solarbuzz, the feed-in tariff for applications less than 100 KwH was €0.42 per KwH in 2005. We currently have an OEM agreement with Isofoton and have recently signed a distribution agreement with Instakciones Pevafersa SL to sell our products in Spain.

	•	China. China passed the Renewable Energy Law in February 28, 2005, which went into effect on January 1, 2006. The Renewable Energy Law authorizes relevant authorities to set favorable prices for the purchase of on-grid solar power-generated electricity, and provides other financial incentives for the development of renewable energy projects. In January 2006, China’s National Development and Reform Commission further promulgated two implementation rules of the Renewable Energy Law, and other implementation rules are expected in the future.


	China finances its off-grid solar installations through the now completed township program and the current village program. The current five-year plan from 2006 to 2010 is targeted to provide electricity to 29,000 villages, mainly in Western China. The Ministry of Construction has recently promulgated directives encouraging the development and use of solar power energy in both urban and rural areas. Various local authorities have also introduced initiatives to encourage the adoption of renewable energy including solar power energy. Furthermore, in October 2005, the Shanghai municipal government endorsed the “100,000 M² Project”, the goal of which is to install solar energy heating systems onto 100,000 M² rooftops in Shanghai in the coming years.

	We believe that we will be well-positioned to take advantage of growth opportunities in the Chinese solar power energy market, which is one of the fastest growing markets for solar power. In April 2006, we began to purchase a limited amount of solar cells from Sharp Solar for our solar module sales in China.


	•	United States. There are now six states that offer significant incentives, with California offering the most preferential incentives. In January 2006, the California Public Utilities Commission enacted the California Solar Initiative, a $2.9 billion program that will subsidize solar power systems by $2.80 per watt. Due to excessive demand, this subsidy has been reduced to the current $2.50 per watt. Combined with federal tax credits for solar power usage, the subsidy may account for as much as 50% of the cost of a solar power system. The program will last from 2007 to 2017 and is expected to dramatically increase the use of solar power for on-grid applications in California.

	•	Canada. In March 2006, the province of Ontario, Canada’s largest province, announced a solar power subsidy, by which a fixed price of C$0.42 per KwH is offered for solar power transferred to the electrical grid starting in the fall of 2006. The program will last 20 years


		and is expected to substantially increase the market for solar power in Ontario. We are working with Carmanah Technologies Inc. in the manufacturing and marketing of solar modules. To support their growth and strategies, much of this will target the Canadian market in general.

	•	Japan. According to Solarbuzz, incentive programs in Japan have led to the installation of more than 200,000 residential solar power systems since the introduction of the programs. Japan is planning to install five GW of generation capacity by 2010. The Japanese government has implemented a series of incentive programs, including the “Solar Power 2030 Roadmap” designed to generate up to 100 GW of solar power electricity by 2030, as well as provide government subsidies for research and development. Solar power energy is becoming increasingly competitive and self-sustained in Japan, and the Japanese government is in the process of completely phasing out direct subsidies to end users of solar power by 2006. Historically, the Japanese solar power market has been relatively closed to non-Japanese solar power players. There have been signs, however, that this market is beginning to open up to international players. In early 2006, we began to sell solar modules on an OEM basis to a leading solar module company in Japan.

Sales and Marketing

Standard Solar Modules

We market and sell our standard solar module products worldwide through a direct sales force. We have direct sales personnel or representatives that cover our markets in Europe, North America and Asia. Our marketing programs include conferences and technology seminars, sales training, trade show exhibitions, public relations and advertising. We sell our products primarily under two types of arrangements, supply contracts and OEM manufacturing arrangements.


	•	Sales contracts. We enter into short-term sales contracts with most of our customers and deliver standard solar modules according to a pre-agreed monthly schedule. Currently, our sales contracts are typically for three months and require our customers to pay 20.0% to 30.0% of the total contract price in advance of delivery as a down payment. We also typically require the payment of the balance contract price by letters of credit or telex money transfers prior to shipping. Our customers typically provide one month purchase order forecasts. As demand and prices stabilize, we plan to enter into longer-term sales contracts to help reduce our exposure to risks from decreases in standard solar module prices generally.

	•	OEM manufacturing arrangements. We obtain solar cell supplies from our OEM customers, and sell to them all of the products we manufacture with those solar cells. Our customers then sell the solar module products under their own brands.

Specialty Solar Modules and Products

In addition to the above efforts, we target our sales and marketing efforts of our specialty solar modules and products at companies in selected industry sectors, including the automotive, telecommunications and LED lighting sectors. As standard solar modules increasingly become commoditized and technology advancements allow for greater usage of solar power in off-grid applications, we will continue to expand our sales and marketing focus on our specialty solar modules and products and capabilities. Our sales and marketing team works with our specialty solar modules and products development team to make certain that we take the changing customer preferences and demands into account in our product development and that our sales and marketing team is able to effectively communicate to customers our product development changes and innovations. To further enhance this communication we will enter into cooperative agreements with our customers to share solar power technical and management expertise in our respective areas of expertise. For example, we entered into a cooperative agreement with Carmanah Technologies in April 2006 to supply solar modules and special value add for some of Carmanah’s lighting products. We intend to establish additional relationships in other market sectors as the specialty solar modules and products market

expands. By jointly developing these products with leading companies in our targeted industry sectors, we will be able to leverage the sales and marketing capabilities of our partners to rapidly build our product portfolio.

Solar Power Development Projects

To date, our solar power development projects have consisted of government grants. Going forward, we will continue to secure and implement large-scale solar power development projects in conjunction with CIDA, the World Bank, the Asian Development Bank, and other government and non-governmental organizations. We will also explore more commercial solar power development projects, which are becoming more prevalent. We seek to participate in a mix of solar power development projects that provide us a continuous, steady source of revenues. These projects will also allow our personnel to further develop project management skills. In addition, we also provide solar power forums, demonstration projects and presentations as part of these solar power development projects, because we believe they generate significant goodwill and publicity for us.

Customer Support and Service

We provide customers with after-sales support, including product return and warranty services. Our standard solar modules are typically sold with a two-year guarantee for defects in materials and workmanship and a 10-year and 25-year warranty against declines of more than 10.0% and 20.0%, respectively, of the initial minimum power generation capacity at the time of delivery. Our specialty solar modules and products are typically sold with a one-year guarantee against defects in materials and workmanship and may, depending on the characteristics of the product, contain a limited warranty of up to ten years, against declines of the minimum power generation capacity specified at the time of delivery.

Research and Development

As of June 30, 2006, we had nine research and product development employees. We currently have approximately twenty technical and engineering employees. Historically, our research and development efforts have focused on reducing manufacturing costs and designing and developing new and efficient specialty solar modules and products to meet customer requirements. Most of our efforts have focused on the manufacturing process and improving efficiencies. We have also focused on designing and improving our silicon reclamation program and improving the yields on recycling reclaimable silicon for reuse in the solar power supply chain. Our research and development team works closely with our manufacturing team, our suppliers and our customers.

Going forward, we will focus on the following research and development initiatives, which, among other projects, we believe will contribute to our competitiveness:

Silicon reclamation technologies: We will seek to improve our technologies and know-how to increase the efficiency of our silicon reclamation program, including increasing the yields on our recovery of scrap silicon. We are developing new technologies and designing equipment for refining certain scrap silicon materials and expanding on the type of materials that can be utilized to manufacture solar cells.

Solar module manufacturing technologies. We intend to focus on developing state-of-the-art testing and diagnostic techniques that improve solar module production yield and efficiency. We are also studying light transmission and reflection technologies inside the solar module to find ways to increase the light absorption of solar cells for the purpose of improving power output.

Product development of specialty solar modules and products. We will seek to improve our product development capabilities for specialty solar modules and products to position ourselves for the expected growth in this area of the solar power market.

Solar cell manufacturing. As we expand into solar cell manufacturing, we plan to invest in the development of process technologies to increase the conversion efficiencies of our solar cells.

New module technologies. We will focus on a series of mid-to-long-term research projects to develop concentrator technologies, high-efficiency cells and next generation solar cells. We will conduct these research projects using both our internal resources and through our collaborative relationships with universities and research institutes.

Competition

The market for solar module products is competitive and continually evolving. We expect to face increased competition, which may result in price reductions, reduced margins or loss of market share. We compete with international companies such as BP Solar, Sharp Solar and SolarWorld and companies located in China such as Suntech Power Holdings Co., Ltd. Many of our competitors have a stronger market position than ours and have larger resources and name recognition than we have. While crystalline technology currently accounts for 94% of the solar power market, many of our competitors are developing or currently producing products based on alternative solar technologies such as thin film photovoltaic materials that may ultimately have costs similar to, or lower than, our projected costs. For example, solar modules produced using thin film materials, such as amorphous silicon and cadmium telluride, are generally less efficient, with conversion efficiencies ranging from 5% to 10% according to Solarbuzz, but require significantly less silicon to produce than crystalline silicon solar modules, such as our products, and are less susceptible to increases in silicon costs. Some of our competitors have also become vertically integrated, from upstream silicon wafer manufacturing to solar system integration. We may also face competition from semiconductor manufacturers, several of which have already announced their intention to start production of solar modules. In addition, the solar power market in general competes with other sources of renewable and alternative energy and conventional power generation. If we fail to compete successfully, we may be unable to expand our customer base and our business will suffer. We believe that the key competitive factors in the market for solar module products include:


	•	supply chain management;

	•	strength of supplier relationships;

	•	manufacturing efficiency;

	•	power efficiency and performance;

	•	price;

	•	customer relationships and distribution channels;

	•	brand name and reputation; and

	•	aesthetic appearance of solar module products.

In the immediate future, because of the growing demand for solar module products and the shortage of high-purity silicon, we believe that the ability to compete in our industry will continue to depend on the ability to effectively manage the supply chain and form strategic relationships. Consolidation of the segments of the solar power supply chain is already occurring and is expected to continue in the near future. We believe that as the supply of high-purity silicon stabilizes, the key to competing successfully will shift to more traditional sales and marketing activities. We believe that the strong relationships that we are building now with both suppliers and customers will support us in that new competitive environment when the time arrives.

Intellectual Property

We have applied to register our trade name, “CSI,” in China, and we are seeking registration of this mark and others in a number of foreign jurisdictions where we conduct business. We currently have one patent and two patent applications pending in China for solar-powered car battery chargers and marine lights. We currently use a combination of contractual arrangements with employees and trade secret protections to establish and protect our proprietary rights. As we expand our specialty solar modules and products portfolio and enter into solar cell manufacturing in the future, we will increase our efforts to develop and protect our intellectual property.

Environmental Regulation

We believe we have obtained all environmental permits necessary to conduct the business currently carried on by us at our existing manufacturing facilities. We have conducted environmental studies in conjunction with our solar power development projects to assess and reduce the environmental impact of our facilities. We believe that our manufacturing processes do not generate any material levels of noise, waste water, gaseous wastes and other industrial wastes and believe that our manufacturing processes are environmentally friendly. We will also continue to devote efforts to ensure that our products comply with the European Union’s Restriction of Hazardous Substances Directive, which takes effect in July 2006, by reducing the amount of lead and other restricted substances used in our solar module products. Our operations are subject to regulation and periodic monitoring by local environmental protection authorities. If we fail to comply with present or future environmental laws and regulations, we could be subject to fines, suspension of production or a cessation of operations.

Employees

As of December 31, 2003, 2004 and 2005, we had 89, 183 and 196 full-time employees. As of June 30, 2006, we had 264 full-time employees. The following table sets forth the number of our employees categorized by our areas of operations and as a percentage of our workforce as of June 30, 2006.


		Number of		Percentage
		Employees		of Total

Manufacturing			178		67.4	%
General and administrative			53		20.1
Research and development			9		3.4
Sales and marketing			24		9.1

	Total		264		100.0	%

As of June 30, 2006, 259 of our employees were located in our two factories in Suzhou and in Changshu, three of our employees were located in our new manufacturing plant in Luoyang and two of our employees were based in Canada. Our employees are not covered by any collective bargaining agreement. We also have contract employees to meet increased demand for our products as required. As of December 31, 2005 and June 30, 2006, we had 52 and 264 contract employees, respectively. We consider our relations with our employees to be good. From time to time, we also employ part-time employees and independent contractors to support our manufacturing, research and development and sales and marketing activities. We plan to hire additional employees as we expand.

Insurance

We maintain property insurance policies with reputable insurance companies for covering our equipment, facilities, buildings and their improvements, office furniture and inventory. These insurance policies cover losses due to fire, floods and other natural disasters. Insurance coverage for our fixed assets in China amounted to approximately $1.2 million as of June 30, 2006. We also maintain product liability insurance with an aggregate coverage amount of approximately $4.3 million, which covers general commercial and product liability. We are in the process of purchasing key-man life insurance for our chairman and chief executive officer, Dr. Shawn Qu. We do not maintain business interruption insurance or

insurance relating to marine, air and inland transit risks for the export of our products. We consider our insurance coverage to be adequate. However, significant damage to any of our manufacturing facilities, whether as a result of fire or other causes, could have a material adverse effect on our results of operation. We paid an aggregate of approximately $50,000 in insurance premiums for 2006 coverage.

Facilities

We have manufacturing facilities and offices in Suzhou that occupy approximately 6,050 square meters under a lease that will expire in March 2008. We have the right to renew the lease on three-months’ prior written notice if the terms we offer are not less favorable than terms offered by other prospective tenants. We also rent offices with an aggregate of approximately 40 square meters in Suzhou for our research and development and certain administrative personnel under a lease expiring in September 2008. In Changshu, we rent our facilities of approximately 4,500 square meters under a three-year lease expiring in September 2007. CSI Luoyang has applied for the land use rights certificate for a piece of land of approximately 5,000 square meters. We plan to begin operations in our Luoyang facility in the first quarter of 2007. CSI Solarchip has applied for the land use rights certificate for a piece of land of approximately 66,667 square meters. We intend to build a solar cell facility in Suzhou and plan to complete our first solar cell line in the first quarter of 2007. We believe our current facilities and our planned facilities will meet our future needs and are consistent with our business plans.

Legal and Administrative Proceedings

In March 2002, ICP Global, a manufacturer of solar power products, filed an action in the Superior Court of the Province of Quebec, Canada (Action No. 500-05 071241-028) against our vice president of international sales and marketing, Gregory Spanoudakis, and ATS. ICP Global contends that Mr. Spanoudakis, who was previously employed by ICP Global, misappropriated its proprietary and commercial business opportunity to sell solar-powered car battery chargers to a prospective customer, Volkswagen Mexico, by directing that opportunity to its competitor ATS. In August 2003, ICP Global amended its complaint to include us, our subsidiary CSI Solartronics and our chairman and chief executive officer, Dr. Shawn Qu, as defendants. The amended complaint contends that all of the defendants jointly engaged in unlawful conduct and unfair competition in directing that business opportunity away from ICP Global to us, as purportedly evidenced by our selling of car battery chargers to Volkswagen Mexico. ICP Global claims damages consisting of an accounting of all profits obtained by the defendants as a result of any misappropriated business opportunity. In its amended complaint, ICP Global claims that the business opportunity could have represented sales of up to $3.0 million.

Although the parties have conducted some basic and minimal discovery, there has been no meaningful discovery, court filings or communications from the plaintiff on this matter since early 2004. We will continue to defend our rights vigorously if ICP Global decides to move forward with this action. Furthermore, we believe that the outcome of the action, even if adversely determined, will not have a material adverse effect on our business or results of operations.

Duties of Directors

Under our governing statute, our directors have a duty of loyalty to act honestly and in good faith with a view to our best interests. Our directors also have a duty to exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances. A shareholder has the right to seek damages if a duty owed by our directors is breached. The functions and powers of our board of directors include, among others:

Committees of the Board of Directors

Our board of directors have established an audit committee, a compensation committee and a corporate governance and nominating committee.

Audit Committee

Our audit committee initially consists of Messrs. Lars-Eric Johannson, Robert McDermott and Arthur Chien, and is chaired by Mr. Johannson, an independent director with accounting and financial management expertise as required by Nasdaq Global Market corporate governance rules. Each of Messrs.

Corporate Governance and Nominating Committee

Our corporate governance and nominating committee initially consists of Lars-Eric Johannson, Robert McDermott and Arthur Chien, each of whom satisfies the “independence” requirements of the Nasdaq Global Market corporate governance rules, and is chaired by Mr. McDermott. The corporate governance and nominating committee assists the board of directors in identifying individuals qualified to become our directors and in determining the composition of the board and its committees.

	•	monitoring compliance with our code of business conduct and ethics, including reviewing the adequacy and effectiveness of our procedures to ensure proper compliance.

Interested Transactions

A director of the corporation who is a party to a material contract or transaction or proposed material contract or transaction with the corporation or is a director or officer of, or has a material interest in, any person who is party to such a contract or transaction is required to disclose in writing or request to have entered into the minutes of meetings of directors the nature and extent of his or her interest. A director may vote in respect of such contract or transaction only if the contract or transaction is: (i) one relating primarily to the remuneration as our director, officer, employee or agent; (ii) one for indemnity or insurance in favor of directors and officers; or (iii) one with an affiliate.

Remuneration and Borrowing

The directors may determine remuneration to be paid to the directors. The compensation committee will assist the directors in reviewing and approving the compensation structure for the directors. The directors may exercise all the powers of the company to borrow money and to mortgage or charge its undertaking,

property and uncalled capital, and to issue debentures or other securities whether outright or as security for any debt obligations of our company or of any third party.

Qualification

There is no shareholding qualification for directors.

Employment Agreements

We have entered into employment agreements with each of our executive officers. Under our employment agreement with Dr. Qu, our chief executive officer and controlling shareholder, Dr. Qu is employed until December 31, 2008, after which time he may terminate his employment with us on three months’ prior written notice. Under our employment agreement with Mr. Gregory Spanoudakis, he may terminate his employment with us at any time on three months’ prior notice. We may terminate either or both of these two employment agreements without cause upon the payment of a severance payment equal to one month of the officer’s base salary for every year of employment with us (up to a maximum of 12 months) together with any unpaid compensation accrued up to the date of the termination.

Apart from these two employment agreements, all of our other employment agreements with our executive officers have a term of three years, ending in 2008 to 2009, except for our employment agreement with Shanglin Shi, which has a term of one year. Under these other employment agreements, either we or the employee may terminate the employment on one month’s prior notice to the other with cause, except that (i) we have the right to terminate the employment of Messrs. Robert Patterson, Bing Zhu, Brian Lu and Genmao Chen for cause at any time without notice; and (ii) the right of each of Messrs. Robert Patterson, Bing Zhu, Brian Lu and Genmao Chen to terminate with cause is limited to material reductions in his authority, duties and responsibilities or a material reduction in his annual salary before the next annual salary review. Furthermore, we may terminate the employment at any time without cause upon one month to three-months’ advance written notice to the executive officer. If we terminate the employment without cause, the executive officer will be entitled to a severance payment equal to three to four months of his then-current base salary. We may terminate each of the agreements for cause, at any time, without notice or remuneration, for certain acts of the employee, including but not limited to a conviction or plea of guilty to a felony, negligence or dishonesty to our detriment and failure to perform agreed duties after a reasonable opportunity to cure the failure.

Each executive officer has agreed to hold, both during and after the employment agreement expires or is earlier terminated, in strict confidence and not to use, except as required in the performance of his duties in connection with the employment, any confidential information, technical data, trade secrets and know-how of our company or the confidential information of any third party, including our affiliated entities and our subsidiaries, received by us. The executive officers have also agreed to disclose in confidence to us all inventions, designs and trade secrets which they conceive, develop or reduce to practice and to assign all right, title and interest in them to us. In addition, each executive officer has agreed to be bound by non-competition restrictions set forth in his or her employment agreement. Specifically, each executive officer has agreed not to, while employed by us and for a period of one to three years following the termination or expiration of the employment agreement, (i) approach our clients, customers or contacts or other persons or entities introduced to the executive officer for the purpose of doing business with such person or entities, and will not interfere with the business relationship between us and such persons and/or entities; (ii) assume employment with or provide services as a director for any of our competitors, or engage, whether as principal, partner, licensor or otherwise, in any business which is in direct or indirect competition with our business; (iii) seek, directly or indirectly, to solicit the services of any of our employees who is employed by us at the date of the executive officer’s termination, or in the year preceding such termination; or (iv) use a name including any word used by our company or our affiliates, or the Chinese or English equivalent or any similar word, in relation to any trade, business or company. Under our employment agreements with our executive officers, for purposes of the non-compete clause described above, a “competitor” of our company is defined as an entity in China or such other territories where we carry on our business. In the case of our agreements with Mr. Robert Patterson, Mr. Bing Zhu and Mr. Brian Lu, the definition of “competitor” is

further limited in that it does not include an entity that generates 10% or less of its revenues from solar power products and services similar to those provided by us, except that if an executive officer is employed by, or provides services as a director or otherwise to, a subsidiary or divisional business of such an entity, such subsidiary or divisional business shall be deemed a “competitor” if it generates more than 10% of its revenues from solar power products and services similar to those provided by us.

Compensation of Directors and Executive Officers

In 2005, the aggregate cash compensation paid to our executive officers, including all the directors, was approximately $493,477.

2006 Share Incentive Plan

We have adopted a share incentive plan, or 2006 Plan, effective in March 2006, to attract and retain the best available personnel for positions of substantial responsibility, provide additional incentives to employees, directors and consultants and promote the success of our business. The maximum aggregate number of common shares which may be issued pursuant to all awards (including options) is 2,330,000 shares, plus for awards other than incentive option shares, an annual increase to be added on the first business day of each calendar year beginning in 2007 equal to the lesser of (x) one percent (1%) of the number of common shares outstanding as of such date, or (y) a lesser number of common shares determined by the board or a designated committee.

The following table summarizes, as of the date of this prospectus, the outstanding options granted under our 2006 plan to several of our directors and executive officers and to other individuals as a group. The options granted in May 2006 vest over a four-year period beginning in March 2006. Unless otherwise noted, all other options granted vest over a four-year period beginning from the date of grant.

The following paragraphs describe the principal terms of our 2006 plan.

Types of Awards. We may grant the following types of awards under our 2006 plan:


	•	options to purchase our common shares; and

	•	restricted shares, which are non-transferable common shares without voting or dividend rights, subject to forfeiture upon termination of a grantee’s employment or service.

Plan Administration. Our board of directors, or a committee designated by our board of directors, will administer the plan. However, with respect to awards made to our non-employee directors, the entire board of directors will administer the plan. The committee or the full board of directors, as appropriate, will determine the provisions and terms and conditions of each award grant.

Award Agreement. Awards granted are evidenced by an award agreement that sets forth the terms, conditions and limitations for each award. In addition, the award agreement also specifies whether the option constitutes an incentive share option or a non-qualifying stock option.

Eligibility. We may grant awards to employees, directors and consultants of our company or any of our related entities, which include our subsidiaries or any entities in which we hold a substantial ownership interest. However, we may grant options that are intended to qualify as incentive share options only to our employees.

100

Acceleration of Awards upon Corporate Transactions. The outstanding awards will accelerate upon occurrence of a change-of-control corporate transaction where the successor entity does not assume our outstanding awards. In such event, each outstanding award will become fully vested and immediately exercisable, and the transfer restrictions on the awards will be released and the repurchase or forfeiture rights will terminate immediately before the date of the change-of-control transaction.

Exercise Price and Term of Awards. In general, the plan administrator determines the exercise price of an option and sets forth the price in the award agreement. The exercise price may be a fixed or variable price related to the fair market value of our common shares. If we grant an incentive share option to an employee who, at the time of that grant, owns shares representing more than 10% of the voting power of all classes of our share capital, the exercise price cannot be less than 110% of the fair market value of our common shares on the date of that grant and the share option is exercisable for no more than five years from the date of that grant.

The term of each award shall be stated in the award agreement. The term of an award shall not exceed 10 years from the date of the grant.

Vesting Schedule. In general, the plan administrator determines, or the award agreement specifies, the vesting schedule.

101

PRINCIPAL AND SELLING SHAREHOLDERS

The following table sets forth information with respect to the beneficial ownership of our common shares as of the date of this prospectus, by:


	•	each of our directors and executive officers;

	•	each person known to us to own beneficially more than 5.0% of our common shares; and

	•	each selling shareholder.

The calculations in the table below assume there are 20,970,000 common shares outstanding as of the date of this prospectus and 27,270,000 common shares outstanding immediately after the closing of this offering, assuming the underwriters do not exercise their over-allotment option.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, we have included shares that the person has the right to acquire within 60 days, including through the exercise of any option, warrant or other right or the conversion of any other security. These shares, however, are not included in the computation of the percentage ownership of any other person.

RELATED PARTY TRANSACTIONS

Unless otherwise indicated, the share numbers in this section do not take into account any post-transaction share splits.

Issuance, Sale and Conversion of Convertible Notes

In November 2005, we issued convertible notes in the aggregate principal amount of $8.1 million to HSBC HAV2 (III) Limited, or HSBC, and JAFCO Asia Technology Fund II, or JAFCO, pursuant to a subscription agreement. In March 2006, we issued HSBC and JACFO convertible notes in the aggregate principal amount of $3.65 million in March 2006 as part of a second tranche subscription and HSBC’s and JAFCO’s option to purchase additional convertible notes under the subscription agreement. The notes were repayable (i) on the third anniversary of their issuance date or (ii) upon the occurrence of an event of default. The notes were convertible into our common shares at the option of the note holders at any time. The notes were automatically convertible into our common shares at the then effective conversion price upon written approval by note holders holding more than 75% of the aggregate principal amount of convertible notes subscribed for by HSBC and JAFCO or upon the completion of this offering. The subscription agreement provided that our board of directors would consist of up to seven directors including one director nominated by each of the two investors. Two directors appointed one each by HSBC and JAFCO served on our board of directors from December 2005 to August 2006. They resigned in August 2006 after HSBC and JAFCO converted their convertible notes into our common shares in July 2006.

Additionally, HSBC and JAFCO agreed in the subscription agreement and convertible notes that Dr. Qu was entitled to all of our retained earnings as of February 28, 2006. In the event that our board of directors declared a dividend or distribution on our common shares prior to an initial public offering or the redemption of all of the convertible notes, we were required to make payments to HSBC and JAFCO at the same time based on their pro rata share of such payments in respect of earnings accumulated after February 28, 2006 (on an as-converted basis).

Conversion of Convertible Notes and Put Option Agreement

On July 1, 2006, HSBC and JAFCO provided notices to convert all of the outstanding convertible notes into our common shares. On that same day, all of the outstanding convertible notes were converted at a conversion price of approximately $5.77 per share. Immediately after the conversion, the Company’s outstanding common shares were immediately split on a 1 for 1.16830772 basis. Common shares issuable pursuant to the Share Incentive Plan or issuable upon the exercise of outstanding awards under the Share Incentive Plan were not affected by this share split. In connection with HSBC’s and JAFCO’s optional conversion of the convertible notes, Dr. Qu, our chief executive officer and controlling shareholder, entered into a put option agreement with HSBC and JAFCO whereby he granted to each of HSBC and JAFCO an option to require him to purchase all of the common shares held by HSBC and JAFCO immediately after the conversion and share split at the same conversion price of the convertible notes. Each of HSBC and JAFCO may exercise its put option: (i) at any time between March 31, 2007 to April 10, 2007 if the Company has not completed a qualified IPO, such as this offering, on or before March 31, 2007; or (ii) upon the occurrence and continuance of an event of default. In connection with the put option agreement, Dr. Qu entered into share pledging agreements with HSBC and JAFCO under which he pledged 1,912,766 and 987,234 of our common shares to HSBC and JAFCO, respectively, as continuing collateral security for his obligations under the put option agreement.

Retained Earnings

Upon the conversion of the convertible notes into our common shares, HSBC and JAFCO acknowledged and agreed that Dr. Qu’s right to our retained earnings as of February 28, 2006 under the convertible notes would remain in effect.

Consultancy Agreements

Prior to December 2005, we paid Dr. Qu, our chairman and chief executive officer, compensation for his services in the form of consultancy fees, on a quarterly basis, to a consulting company owned by him. The consultancy agreement was non-written and provided for consultancy fees to be paid to Dr. Qu in return for the project consulting, general management and technology services that he provided to us. We terminated the consulting agreement with Dr. Qu in November 2005. In 2003, 2004 and 2005, we paid consulting fees to Dr. Qu’s consulting company in the amount of $79,172, $152,430 and $172,298, respectively.

Under the agreement, Mr. Patterson provided project consulting services to us, in particular in connection with our large-scale CIDA projects, for 40 hours per month with a minimum retainer of C$2,000 per month. For additional work beyond the initial period and minimum retainer, Mr. Patterson was paid on an hourly basis. We terminated the consulting agreement with Mr. Patterson in December 2005.

Dr. Qu also entered into share pledge agreements whereby he agreed to mortgage, charge and assign by way of a first legal mortgage 755,789 common shares to HSBC and 377,895 common shares to JAFCO as a continuing security for the due and punctual performance and observance by us of our obligations under the subscription agreement. The share pledges were irrevocably and unconditionally released by HSBC and JAFCO in March 2006 in connection with the second tranche subscription and per the terms of the subscription agreement.

In September 2005, Dr. Qu guaranteed the performance of our obligations in connection with a $1.3 million promissory note that we issued to ATS in September 2005. He also entered into a share pledge agreement with ATS whereby he pledged 200,000 common shares to ATS as security for our performance of our obligations under this promissory note. The ATS promissory note is secured and interest-bearing pursuant to the underlying security agreement between us and ATS. The sum of the principal, together with interest calculated semi-annually at the interest rate published from time to time by a major Canadian chartered bank, is repayable on demand. The outstanding balances of the loan as of December 31, 2005 and June 30, 2006 were, $1.3 million and $1.3 million, respectively. Interest of $21,726 and $49,919 was paid or payable for 2005 and the first six months of 2006, respectively.

CHINESE GOVERNMENT REGULATIONS

This section sets forth a summary of the most significant regulations or requirements that affect our business activities in China or our shareholders’ right to receive dividends and other distributions from us.

Renewable Energy Law and Other Government Directives

In February 2005, China enacted its Renewable Energy Law, which became effective on January 1, 2006. The Renewable Energy Law sets forth policies to encourage the development and use of solar energy and other non-fossil energy. The renewable energy law sets forth the national policy to encourage and support the use of solar and other renewable energy and the use of on-grid generation. It also authorizes the relevant pricing authorities to set favorable prices for the purchase of electricity generated by solar and other renewable power generation systems.

The law also sets forth the national policy to encourage the installation and use of solar energy water-heating system, solar energy heating and cooling system, solar photovoltaic system and other solar energy utilization systems. It also provides financial incentives, such as national funding, preferential loans and tax preferences for the development of renewable energy projects. In January 2006, China’s National Development and Reform Commission promulgated two implementation directives of the Renewable Energy Law. These directives set forth specific measures in setting prices for electricity generated by solar and other renewal power generation systems and in sharing additional expenses occurred. The directives further allocate the administrative and supervisory authorities among different government agencies at the national and provincial levels and stipulate responsibilities of electricity grid companies and power generation companies with respect to the implementation of the renewable energy law.

China’s Ministry of Construction also issued a directive in June 2005, which seeks to expand the use of solar energy in residential and commercial buildings and encourages the increased application of solar energy in different townships. In addition, China’s State Council promulgated a directive in July 2005, which sets forth specific measures to conserve energy resources.

Environmental Regulations

We believe that our manufacturing processes do not generate any material levels of noise, waste water, gaseous wastes and other industrial wastes and believe that our manufacturing processes are environmentally benign. We are subject to a variety of governmental regulations related to the storage, use and disposal of hazardous materials. The major environmental regulations applicable to us include the Environmental Protection Law of the PRC, the Law of PRC on the Prevention and Control of Water Pollution, Implementation Rules of the Law of PRC on the Prevention and Control of Water Pollution, the Law of PRC on the Prevention and Control of Air Pollution, the Law of PRC on the Prevention and Control of Solid Waste Pollution, and the Law of PRC on the Prevention and Control of Noise Pollution.

Restriction on Foreign Businesses

The principal regulation governing foreign ownership of solar power businesses in the PRC is the Foreign Investment Industrial Guidance Catalogue (effective as of January 1, 2005). Under the regulation, the solar power business belongs to permitted foreign investment industry.

Tax

PRC enterprise income tax is calculated based on taxable income determined under PRC accounting principles. In accordance with “Income Tax of China for Enterprises with Foreign Investment and Foreign Enterprises,” or the Income Tax Law, and the related implementing rules, foreign invested enterprises incorporated in the PRC are generally subject to an enterprise income tax at the rate of 30% on taxable income and local income tax at the rate of 3% of taxable income. The Income Tax Law and the related implementing rules provide certain favorable tax treatments to foreign invested enterprises such as a two-year exemption from enterprise income tax for their first two profitable years of operation and thereafter a 50% tax

107

deduction for the subsequent three years for manufacturing companies with operation terms of more than ten years.

Pursuant to the Provisional Regulation of China on Value Added Tax and their implementing rules, all entities and individuals that are engaged in the sale of goods, the provision of repairs and replacement services and the importation of goods in China are generally required to pay VAT at a rate of 17.0% of the gross sales proceeds received, less any deductible VAT already paid or borne by the taxpayer. Further, when exporting goods, the exporter is entitled to a portion of or all the refund of VAT that it has already paid or borne. Our imported raw materials that are used for manufacturing export products and are deposited in bonded warehouses are exempt from import VAT.

Foreign Currency Exchange

Foreign currency exchange regulation in China is primarily governed by the following rules:


	•	Foreign Currency Administration Rules (1996), as amended, or the Exchange Rules; and

	•	Administration Rules of the Settlement, Sale and Payment of Foreign Exchange (1996), or the Administration Rules;

Currently, the Renminbi is convertible for current account items, including the distribution of dividends, interest payments, trade and service-related foreign exchange transactions. Conversion of Renminbi for most capital account items, such as direct investment, security investment and repatriation of investment, however, is still subject to the approval of the PRC State Administration of Foreign Exchange, or SAFE.

Under the Administration Rules, foreign-invested enterprises may buy, sell and/or remit foreign currencies only at those banks authorized to conduct foreign exchange business after providing valid commercial documents and, in the case of most capital account item transactions, obtaining approval from the SAFE. Capital investments by foreign-invested enterprises outside of China are also subject to limitations, which include approvals by the Ministry of Commerce, the SAFE and the State Reform and Development Commission.

Dividend Distribution

The principal regulations governing distribution of dividends paid by wholly foreign owned enterprises include:


	•	Wholly Foreign Owned Enterprise Law (1986), as amended; and

	•	Wholly Foreign Owned Enterprise Law Implementation Rules (1990), as amended.

Under these regulations, foreign-invested enterprises in China may pay dividends only out of their accumulated profits, if any, determined in accordance with PRC accounting standards and regulations. In addition, a wholly foreign owned enterprise in China is required to set aside at least 10.0% of their after-tax profit based on PRC accounting standards each year to its general reserves until the accumulative amount of such reserves reach 50.0% of its registered capital. These reserves are not distributable as cash dividends. The board of directors of a foreign-invested enterprise has the discretion to allocate a portion of its after-tax profits to staff welfare and bonus funds, which may not be distributed to equity owners except in the event of liquidation.

108

DESCRIPTION OF SHARE CAPITAL

We are a Canadian corporation, and our affairs are governed by our articles of incorporation, as amended from time to time, bylaws as effective from time to time, and the Canada Business Corporations Act, which is referred to as the CBCA below.

As of the date of this prospectus, our authorized share capital consists of an unlimited number of common shares. As of the date of this prospectus, 20,970,000 common shares were issued and outstanding.

The following summary description of our share capital does not purport to be complete and is qualified in its entirety by reference to our articles of continuance as amended and the amended bylaws that we intend to adopt effective upon the completion of this offering. If you would like more information on our common shares, you should review our articles and bylaws, which we have filed as an exhibit to the registration statement that includes this prospectus, and the CBCA.

Common Shares

General

All of our common shares are fully paid and non-assessable. Our common shares are issued in registered form and may or may not be certificated although every shareholder is entitled at their option to a share certificate that complies with the CBCA. There are no limitations on the rights of shareholders who are not residents of Canada to hold and vote common shares.

Dividends

Holders of our common shares are entitled to receive, from funds legally available therefor, dividends when and as declared by the board of directors. The CBCA restricts the directors’ ability to declare, and our ability to pay, dividends by requiring that certain solvency tests be satisfied at the time of such declaration and payment. See “— Shareholders’ Rights — Sources of Dividends.”

Voting Rights

Each common share is entitled to one vote on all matters upon which the common shares are entitled to vote.

Liquidation

With respect to a distribution of assets in the event of our liquidation, dissolution or winding-up, whether voluntary or involuntary, or any other distribution of our assets for the purposes of winding up our affairs, assets available for distribution among the holders of common shares shall be distributed among the holders of the common shares on a pro rata basis.

Variations of Rights of Shares

All or any of the rights attached to our common shares, or any other class of shares duly authorized may, subject to the provisions of the CBCA, be varied either with the unanimous written consent of the holders of the issued shares of that class or by a special resolution passed at a meeting of the holders of the shares of that class.

Preferred Shares

After the closing of this offering, our board of directors will have the authority, without shareholder approval, to issue an unlimited number of preferred shares in one or more series. Our board of directors may establish the number of shares to be included in each such series and may set the designations, preferences, powers and other rights of the shares of a series of preferred shares. While the issuance of preferred shares provides us with flexibility in connection with possible acquisitions or other corporate purposes, it could, among other things, have the effect of delaying, deferring or preventing a change of control transaction and

109

could adversely affect the market price of our common shares. We have no current plan to issue any preferred shares.

Transfer Agent and Registrar

The Bank of New York is the transfer agent and registrar for our common shares. The Bank of New York’s address is One Wall Street, New York, New York 10286.

Shareholders’ Rights

The CBCA and our articles of continuance and bylaws govern us and our relations with our shareholders. The following is a summary of certain rights of holders of our common shares under the CBCA. This summary is not intended to be complete and is qualified in its entirety by reference to our articles of continuance and bylaws.

Stated Objects or Purposes

Our articles of continuance do not contain any stated objects or purposes and do not place any limitations on the business that we may carry on.

Shareholder Meetings

We must hold an annual meeting of our shareholders at least once every year at a time and place determined by our board of directors, provided that the meeting must not be held later than 15 months after the preceding annual meeting or later than six months after the end of our preceding financial year. A meeting of our shareholders may be held at a place within Canada determined by our directors or, if determined by our directors, in New York, New York, United States of America, Los Angeles, California, United States of America, London, England, the Hong Kong Special Administrative Region of The People’s Republic of China or Shanghai, The People’s Republic of China.

Voting at any meeting of shareholders is by show of hands unless a poll or ballot is demanded. A poll or ballot may be demanded by the chairman of our board of directors or by any shareholder present in person or by proxy.

A special resolution is a resolution passed by not less than two-thirds of the votes cast by the shareholders entitled to vote on the resolution at a meeting at which a quorum is present. An ordinary resolution is a resolution passed by not less than a simple majority of the votes cast by the shareholders entitled to vote on the resolution at a meeting at which a quorum is present.

Notice of Meeting of Shareholders

Our bylaws provide that written notice stating the place, day and time of a shareholder meeting and the purpose for which the meeting is called, shall be delivered not less than 21 days nor more than 60 days before the date of the meeting.

Quorum

Under the CBCA, unless a corporation’s bylaws provide otherwise, a quorum is present at a meeting of the shareholders, irrespective of the number of shareholders actually present at the meeting, if the holders of a majority of the shares entitled to vote at the meeting are present in person or represented by proxy. Our bylaws provide that a quorum shall be at least two shareholders entitled to vote at the meeting represented in person or by proxy and holding at least one-third of our total issued and outstanding common shares.

Record Date for Notice of Meeting of Shareholders

The directors may fix in advance a date as the record date for the determination of shareholders entitled to receive notice of a meeting of shareholders, but such record date shall not precede by more than

110

60 days or by less than 21 days the date on which the meeting is to be held. If no record date is fixed, the record date for the determination of shareholders entitled to receive notice of a meeting of shareholders shall be at the close of business on the day immediately preceding the day on which the notice is given or, if no notice is given, the day on which the meeting is held. If a record date is fixed, notice thereof shall be given, not less than seven days before the date so fixed by newspaper advertisement in the manner provided by the CBCA and by written notice to each stock exchange in Canada on which our shares are listed for trading.

Ability to Requisition Special Meetings of the Shareholders

The CBCA provides that the holders of not less than five percent of the issued shares of a corporation that carry the right to vote at a meeting sought to be held may give notice to the directors requiring them to call a meeting.

Shareholder Proposals

A shareholder entitled to vote at a meeting of shareholders who has held common shares with a fair market value of at least C$2,000 for at least six months may submit to the corporation notice of a proposal and discuss at the meeting any matter in respect of which the shareholder would have been entitled to submit a proposal. A proposal may include nominations for the election of directors if the proposal is signed by one or more holders of shares representing in the aggregate not less than five percent of the shares entitled to vote at the meeting to which the proposal is to be presented. This requirement does not preclude nominations being made at a meeting of shareholders. The proposal must be submitted to the corporation at least 90 days before the anniversary date of the notice of meeting that was sent to shareholders in connection with the last annual meeting.

Vote Required for Extraordinary Transactions

Under the CBCA, certain extraordinary corporate actions are required to be approved by special resolution. Such extraordinary corporate actions include:


	•	amendments to articles;

	•	arrangements;

	•	amalgamations other than amalgamations involving a holding body corporate, one or more wholly owned subsidiaries and/or one or more sister corporations;

	•	continuances under the laws of another jurisdiction;

	•	voluntary dissolutions; and

	•	sales, leases or exchanges of all or substantially all the property of a corporation other than in the ordinary course of business.

Related Party Transactions

The CBCA does not prohibit related party transactions.

Dissent Rights

The CBCA provides that shareholders of a corporation are entitled to exercise dissent rights and demand payment of the fair value of their shares in certain circumstances. For this purpose, there is no distinction between listed and unlisted shares. Dissent rights exist when a corporation resolves to:


	•	amalgamate with a corporation other than a holding body corporate, one or more wholly owned subsidiaries and/or one or more sister corporations;

	•	amend the corporation’s articles of incorporation to add, change or remove any provisions restricting the issue, transfer or ownership of shares;

111


	•	amend the corporation’s articles to add, change or remove any restriction upon the business or businesses that the corporation may carry on;

	•	continue under the laws of another jurisdiction;

	•	sell, lease or exchange of all or substantially all the property of the corporation other than in the ordinary course of business; or

	•	carry out a going-private or squeeze-out transaction.

In addition, a court order in connection with an arrangement proposed by the corporation may permit shareholders to dissent if the arrangement is adopted.

However, a shareholder is not entitled to dissent if an amendment to the articles of incorporation is effected by a court order approving a reorganization or by a court order made in connection with an action for an oppression remedy.

Action by Written Consent

Under the CBCA, shareholders can take action by written resolution and without a meeting only if all shareholders sign the written resolution.

Directors

Number of Directors and Election

Under the CBCA the number of directors of a corporation must be specified in the corporation’s articles. The articles may provide for a minimum and maximum number of directors.

Our articles of incorporation provide that the number of directors will not be less than three or more than ten. Our board of directors currently consists of five directors.

Shareholders of a corporation governed by the CBCA elect directors by ordinary resolution at each annual meeting of shareholders at which such an election is required.

Director Qualifications

Under the CBCA, at least 25% of the directors must be Canadian residents. A director must not be:


	•	under eighteen years of age;

	•	adjudicated as mentally unsound;

	•	a person that is not an individual; or

	•	a person who has the status of a bankrupt.

Removal of Directors; Staggered Term

Under the CBCA, a corporation’s shareholders may remove any director before the expiration of his or her term of office and may elect any qualified person in such director’s stead for the remainder of such term by ordinary resolution.

Under the CBCA, directors may be elected for a term expiring not later than the third annual meeting of shareholders following the election. If no term is specified, a director’s term expires at the next annual meeting of shareholders. A director may be nominated for re-election to the board of directors at the end of the director’s term.

Vacancies on the Board of Directors

Under the CBCA, vacancies that exist on the board of directors, except a vacancy resulting from an increase in the number or the minimum or maximum number of directors or a failure to elect the number or

112

minimum number of directors provided for in the articles, may be filled by the board if the remaining directors constitute a quorum. In the absence of a quorum, the remaining directors shall call a meeting of shareholders to fill the vacancy.

Limitation of Personal Liability of Directors and Officers

Under the CBCA, in exercising their powers and discharging their duties, directors and officers must act honestly and in good faith with a view to the best interests of the corporation and exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances. No provision in the corporation’s articles, bylaws, resolutions or contracts can relieve a director or officer from the duty to act in accordance with the CBCA or relieve a director from liability for a breach thereof. However, a director will not be liable for breaching his or her duty to act in accordance with the CBCA if the director relied in good faith on:


	•	financial statements represented to him by an officer or in a written report of the auditor to present fairly the financial position of the corporation in accordance with generally accepted accounting principles; or

	•	a report of a person whose profession lends credibility to a statement made by such person.

Indemnification of Directors and Officers

Under the CBCA and pursuant to our bylaws, we may indemnify any present or former director or officer or an individual who acts or acted at our request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by such individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of that association with the corporation or other entity. In order to qualify for indemnification such director or officers must:


	•	have acted honestly and in good faith with a view to the best interests of the corporation; and

	•	in the case of a criminal or administrative action or proceeding enforced by a monetary penalty, have had reasonable grounds for believing that his or her conduct was lawful.

Indemnification will be provided to an eligible director or officer who meets both these tests and was substantially successful on the merits in his or her defense of the action.

A director or officer is entitled to indemnification from us as a matter of right if he or she is not judged by the court or other competent authority to have committed any fault or omitted to do anything that the individual ought to have done and fulfilled the conditions set forth above.

Sources of Dividends

Dividends may be declared at the discretion of the board of directors. Under the CBCA, the directors may not declare, and we may not pay, pay dividends if there are reasonable grounds for believing that (i) we are, or would after such payment be unable to pay our liabilities as they become due or (ii) the realizable value of our assets would be less than the aggregate of our liabilities and of our stated capital of all classes of shares.

Amendments to the Bylaws

The directors may by resolution make, amend or repeal any bylaw unless the articles or bylaws provide otherwise. Our articles and bylaws do not restrict the power of our directors to make, amend or repeal bylaws. When the directors make, amend or repeal a bylaw, they are required under the CBCA to submit the change to the shareholders at the next meeting of shareholders. Shareholders may confirm, reject or amend the bylaw, amendment or repeal by ordinary resolution.

113

Interested Directors Transactions

Under the CBCA, if a director or officer has a material interest in a material contract or transaction, the director generally may not vote on any resolution to approve the contract or transaction, but the contract is not void or voidable by reason only of the relationship if such interest is disclosed in accordance with the requirements set out in the CBCA, the contract is approved by the other directors or by the shareholders and the contract was fair and reasonable to the corporation at the time it was approved.

Where a director or officer has an interest in a material contract or transaction or a proposed material contract or transaction that, in the ordinary course of the corporation’s business, would not require approval by the directors or shareholders, the interested director or officer shall disclose in writing to the corporation or request to have entered in the minutes of meetings of directors, the nature and the extent of the interest forthwith after the director or officer becomes aware of the contract or transaction or proposed contract or transaction.

Committees

Under the CBCA, directors of a corporation may appoint from their number a committee of directors and delegate to such committee certain powers of the directors.

Derivative Actions

Under the CBCA, a complainant (as defined below) may apply to the court for leave to bring an action in the name of and on behalf of a corporation or any of its subsidiaries, or to intervene in an existing action to which such body corporate is a party for the purpose of prosecuting, defending or discontinuing the action. A complainant includes a present or former shareholder, a present or former officer or director of the corporation or any of its affiliates, or any other person who in the discretion of the court is a proper person to make such an application. Under the CBCA, no action may be brought and no intervention in an action may be made unless the complainant has given 14 days’ notice to the directors of the corporation or its subsidiary of the complainant’s intention to apply to the court. The court must be satisfied that:


	•	the complainant is acting in good faith; and

	•	it appears to be in the interests of the corporation or its subsidiary that the action be brought, prosecuted, defended or discontinued.

Under the CBCA, the court in a derivative action may make any order it thinks fit, including orders pertaining to the conduct of the action, the making of payments to former and present shareholders and payment of reasonable legal fees incurred by the complainant.

Oppression Remedy

The CBCA provides an oppression remedy that enables a court to make any order it thinks fit to rectify the matters complained of, if the court is satisfied upon application of a complainant (as defined below) that:


	•	any act or omission of the corporation or any of its affiliates effects a result;

	•	the business or affairs of the corporation or any of its affiliates are or have been conducted in a manner; or

	•	the powers of the directors of the corporation or any of its affiliates are or have been exercised in a manner,

that is oppressive or unfairly prejudicial to or that unfairly disregards the interests of any security holder, creditor, director or officer of the corporation.

114

A complainant for this purpose includes a present or former shareholder, a present or former officer or director of the corporation or any of its affiliates, the Director appointed under the CBCA and any other person who in the discretion of the court is a proper person to make such an application.

The exercise of the court’s jurisdiction does not depend on a finding of a breach of such legal and equitable rights. Furthermore, the court may order a corporation to pay the interim costs of a complainant seeking an oppression remedy, but the complainant may be held accountable for such interim costs on final disposition of the complaint.

Inspection of Books and Records

Under the CBCA, shareholders and the creditors of the corporation and, their personal representatives may examine, free of charge during normal business hours:


	•	the articles, bylaws and all amendments thereto, of the corporation;

	•	the minutes and resolutions of shareholders:

	•	copies of all notices of directors filed under the CBCA; and

	•	the securities register of the corporation.

All shareholders of the corporation may request a copy of the articles, bylaws and all amendments thereto free of charge.

Exchange Controls

Canada has no system of exchange controls. There are no Canadian restrictions on the repatriation of capital or earnings of a Canadian public company to non-resident investors. There are no laws of Canada or exchange restrictions affecting the remittance of dividends or similar payments to non-resident holders of our common shares, except as described under “Taxation — Material Canadian Income Tax Considerations.”

History of Securities Issuances

The following is a summary of our securities issuances during the past three years.

In November 2005, we issued convertible notes in the aggregate principal amount of $8.1 million to HSBC and JAFCO pursuant to a subscription agreement. We issued HSBC and JAFCO convertible notes in the aggregate principal amount of $3.65 million in March 2006 as part of a second tranche subscription and HSBC’s and JAFCO’s option to purchase additional convertible notes under the subscription agreement. The notes were repayable (i) on the third anniversary of their issuance date or (ii) upon the occurrence of an event of default, whichever occurs earlier. The notes were convertible into our common shares at the option of the note holders at any time. The notes were automatically convertible into our common shares at the then effective conversion price upon written approval by note holders holding more than 75% of the aggregate principal amount of convertible notes subscribed for by HSBC and JAFCO or upon the completion of this offering. The first tranche and second tranche notes of both HSBC and JAFCO were converted into our

115

common shares in July 2006. After the conversion and an immediate one to 1.168130772 share split in connection therewith, HSBC and JAFCO held 1,568,826 and 809,717 common shares respectively.

Registration Rights

We have granted registration rights to HSBC and JAFCO in connection with their subscription for the notes in November 2005. Set forth below is a description of the registration rights granted to HSBC and JAFCO.

Demand Registration Rights. At any time commencing six months after this offering, holders of at least 25% of the registrable securities have the right to demand that we file a registration statement covering the offer and sale of their securities. However, we are not obligated to effect any such demand registration if we have within the twelve month period preceding the demand already effected two or more demand registrations or Form F-3 or S-3 registrations. We have the right to defer the filing of a registration statement for up to 120 days if our board of directors determines in good faith that there is a valid business reason to delay the filing. We are not obligated to effect such demand registrations on more than three occasions.

Form F-3 Registration Rights. Upon our becoming eligible to use Form F-3 or S-3, holders of at least 75% of the registrable securities have the right to request that we file a registration statement under Form F-3 or S-3 if the aggregate amount of securities to be sold under the registration statement is not less than $1.0 million. Such requests for registrations are not counted as demand registrations.

Piggyback Registration Rights. If we propose to file a registration statement with respect to an offering for our own account or for the account of any person that is not a holder of registrable securities, we must offer holders of registrable securities the opportunity to include their securities in the registration statement, other than pursuant to a registration statement on Form F-4, S-4 or S-8, or a registration statement in connection with any demand or Form F-3 registration initiated by the holder(s) of registrable securities. Such requests for registrations are not counted as demand registrations.

Expenses of Registration. We will pay all expenses relating to any demand, piggyback or Form F-3 registration, except that holders of registrable securities shall bear the expense of any underwriting discounts or commission relating to registration and sale of their shares.

In October 2006, we also granted registration rights to ATS. The registration rights granted to ATS are substantially similar as that granted to HSBC and JAFCO as described above, except that we are not obligated to effect a demand registration of ATS on more than two occasions.

116

SHARES ELIGIBLE FOR FUTURE SALE

The common shares being offered in this offering represent approximately 28.24% of our common shares in issue. All of the common shares sold in this offering will be freely transferable by persons other than our “affiliates” without restriction or further registration under the Securities Act. Sales or perceived sales of substantial amounts of our common shares in the public market could adversely affect prevailing market prices of our common shares. Prior to this offering, there has been no public market for our common shares, and although our application to have the common shares to be listed on the Nasdaq Global Market has been approved, we cannot assure you that a regular trading market for our common shares will develop.

Lock-up Agreements

Each of the selling shareholders, our directors, executive officers and our other existing shareholders has agreed, subject to some exceptions, not to transfer or dispose of, directly or indirectly, any of our common shares, or any securities convertible into or exchangeable or exercisable for our common shares, for a period of 180 days after the date this prospectus becomes effective. After the expiration of the 180-day period, the common shares held by the selling shareholders, our directors, executive officers or certain of our other existing shareholders may be sold subject to the restrictions under Rule 144 under the Securities Act or by means of registered public offerings.

The 180-day restricted period is subject to adjustment under certain circumstances. If (1) during the last 17 days of the 180-day restricted period, we issue an earnings release or material news or a material event relating to us occurs; or (2) prior to the expiration of the 180-day restricted period, we announce that we will release earnings results during the 16-day period beginning on the last day of the 180-day period, the restrictions will continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, unless, with respect to the restricted period applicable to us, the selling shareholders, directors and executive officers and the other shareholders of our company, such extension is waived by the representatives on behalf of the underwriters. See “Underwriting.”

Rule 144

In general, under Rule 144 as currently in effect, beginning 90 days after the date of this prospectus, a person who has beneficially owned “restricted securities” for at least one year would be entitled to sell in the United States, within any three-month period, a number of shares that is not more than the greater of:


	•	1.0% of the number of our common shares then outstanding which will equal approximately 272,700 common shares immediately after this offering; or

	•	the average weekly reported trading volume of our common shares on the Nasdaq Global Market during the four calendar weeks proceeding the date on which a notice of the sale on Form 144 is filed with the SEC by such person.

Sales under Rule 144 are also subject to manner-of-sale provisions, notice requirements and the availability of current public information about us. However, these shares would remain subject to lock-up arrangements and would only become eligible for sale when the lock-up period expires. Persons who are not our affiliates may be exempt from these restrictions under Rule 144(k) discussed below.

Rule 144(k)

Under Rule 144(k), a person who is not deemed to have been our affiliate at any time during the three months preceding a sale, and who has beneficially owned the common shares proposed to be sold for at least two years from the later of the date these shares were acquired from us or from our affiliate, including the holding period of any prior owner other than an affiliate, is entitled to sell those shares in the United States immediately following this offering without complying with the manner-of-sale, public information, volume limitation or notice provisions of Rule 144. However, these shares would remain subject to lock-up arrangements and would only become eligible for sale when the lock-up period expires.

117

Rule 701

Beginning 90 days after the date of this prospectus, persons other than affiliates who purchased common shares under a written compensatory plan or contract may be entitled to sell such shares in the United States in reliance on Rule 701. Rule 701 permits affiliates to sell their Rule 701 shares under Rule 144 without complying with the holding period requirements of Rule 144. Rule 701 further provides that non-affiliates may sell these shares in reliance on Rule 144 subject only to its manner-of-sale requirements. However, the Rule 701 shares would remain subject to lock-up arrangements and would only become eligible for sale when the lock-up period expires.

Registration Rights

Upon completion of this offering, certain holders of our common shares or their transferees will be entitled to request that we register their shares under the Securities Act, following the expiration of the lock-up agreements described above. See “Description of Share Capital — Registration Rights.”

TAXATION

The following summary of the material Canadian and United States federal tax consequences of an investment in our common shares is based upon laws and relevant interpretations thereof in effect as of the date of this prospectus, all of which are subject to change. This summary does not deal with all possible tax consequences relating to an investment in our common shares, such as the tax consequences under U.S., state, local and other tax laws. To the extent that the discussion relates to matters of Canadian tax law, it represents the opinion of WeirFoulds LLP, our Canadian counsel.

Material Canadian Federal Tax Considerations

General

The following summary is of the material Canadian federal tax implications applicable to a holder (a “US Holder”) who acquires common shares of CSI (the “Common Shares”) pursuant to this offering and who, at all relevant times, for purposes of the Income Tax Act (Canada) (the “Canadian Tax Act”) (i) has not been, is not and will not be resident (or deemed resident) in Canada at any time while such US Holder has held or holds the Common Shares; (ii) holds the Common Shares as capital property; (iii) deals at arm’s length with and is not affiliated with CSI; (iv) does not use or hold, and is not deemed to use or hold, the Common Shares in the course of carrying on a business in Canada; (v) did not acquire the Common Shares in respect of, in the course of or by virtue of employment with our company; (vi) is not a financial institution, specified financial institution, partnership or trust as defined in the Canadian Tax Act; (vii) is a resident of the United States for purposes of the Canada-United States Income Tax Convention (1980), as amended (the “Convention”); and (viii) has not, does not and will not have a fixed base or permanent establishment in Canada within the meaning of the Convention at any time while such US Holder has held or holds the Common Shares. Special rules, which are not addressed in this summary, may apply to a US Holder that is a “registered non-resident insurer” or “authorized foreign bank”, as defined in the Canadian Tax Act, carrying on business in Canada and elsewhere.

The current published policy of the Canada Revenue Agency (the “CRA”) is that certain entities (including most limited liability companies) that are treated as being fiscally transparent for United States federal income tax purposes will not qualify as residents of the United States for purposes of the Convention.

This summary is based on the current provisions of the Canadian Tax Act, and the regulations thereunder, the Convention, and counsel’s understanding of the published administrative practices and policies of the CRA, all in effect as of the date of this Prospectus. This summary takes into account all specific proposals to amend the Canadian Tax Act or the regulations thereunder publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date of this prospectus. No assurances can be given that such proposed amendments will be enacted in the form proposed, or at all. This summary is not exhaustive of all potential Canadian federal tax consequences to a US Holder and does not take into account or anticipate any other changes in law or administrative practices, whether by judicial, governmental or legislative action or decision, nor does it take into account provincial, territorial or foreign tax legislation or considerations, which may differ from the Canadian federal tax considerations described herein.

TAX MATTERS ARE VERY COMPLICATED AND THE CANADIAN FEDERAL TAX CONSEQUENCES OF PURCHASING, OWNING AND DISPOSING OF COMMON SHARES WILL DEPEND ON THE SHAREHOLDER’S PARTICULAR SITUATION. THIS SUMMARY IS NOT INTENDED TO BE A COMPLETE ANALYSIS OF OR DESCRIPTION OF ALL POTENTIAL CANADIAN FEDERAL TAX CONSEQUENCES, AND SHOULD NOT BE CONSTRUED TO BE, LEGAL, BUSINESS OR TAX ADVICE DIRECTED AT ANY PARTICULAR PROSPECTIVE PURCHASER OF COMMON SHARES. ACCORDINGLY, PROSPECTIVE PURCHASERS OF COMMON SHARES SHOULD CONSULT THEIR OWN TAX ADVISORS FOR ADVICE WITH RESPECT TO THE CANADIAN FEDERAL TAX CONSEQUENCES TO THEM OF AN INVESTMENT IN COMMON SHARES BASED ON THEIR PARTICULAR CIRCUMSTANCES.

119

Dividends

Amounts paid or credited, or deemed under the Canadian Tax Act to be paid or credited as, on account or in lieu of payment of, or in satisfaction of, dividends to a US Holder that is a beneficial owner of Common Shares will be subject to Canadian non-resident withholding tax at the reduced rate of 15% under the Convention. This rate is further reduced to 5% in the case of a US Holder that is a beneficial owner of Common Shares and is a company for purposes of the Convention that owns at least 10% of the voting shares of CSI at the time the dividend is paid or deemed to be paid. Under the Convention, dividends paid or credited to certain religious, scientific, literary, educational or charitable organizations and certain pension organizations that are resident in the United States and that have complied with certain administrative procedures may be exempt from Canadian withholding tax.

Disposition of Our Common Shares

A US Holder will not be subject to tax under the Canadian Tax Act in respect of any capital gain realized on the disposition or deemed disposition of the Common Shares unless, at the time of disposition, the Common Shares constitute “taxable Canadian property” of the US Holder for the purposes of the Canadian Tax Act. The Common Shares will not constitute “taxable Canadian property” to a US Holder provided that (i) the Common Shares are, at the time of disposition, listed on a prescribed stock exchange for purposes of the Canadian Tax Act (which currently includes Nasdaq); and (ii) at no time during the 60-month period immediately preceding the disposition of the Common Shares did the US Holder, persons with whom the US Holder did not deal at arm’s length, or the US Holder together with such persons, own 25% or more of the issued shares of any class or series of the capital stock of CSI. Provided the Common Shares are listed on Nasdaq or another prescribed stock exchange at the time of a disposition thereof, the preclearance provisions of the Canadian Tax Act will not apply to the disposition.

Pursuant to the Convention, even if the Common Shares constitute “taxable Canadian property” of a particular US Holder, any capital gain realized on the disposition of the Common Shares by the US Holder generally will be exempt from tax under the Canadian Tax Act, unless, at the time of disposition, the Common Shares derive their value principally from real property situated in Canada within the meaning of the Convention.

United States Federal Taxation

The following discussion describes the material U.S. federal income and estate tax consequences to U.S. Holders (defined below) under present law of an investment in our common shares. This summary applies only to investors that hold our common shares as capital assets and that have the U.S. dollar as their functional currency. This discussion is based on the tax laws of the United States as in effect on the date of this prospectus and on U.S. Treasury regulations in effect or, in some cases, proposed, as of the date of this prospectus, as well as judicial and administrative interpretations thereof available on or before such date. All of the foregoing authorities are subject to change, which change could apply retroactively and could affect the tax consequences described below.

The following discussion does not deal with the tax consequences to any particular investor or to persons in special tax situations such as:


	•	banks;

	•	certain financial institutions;

	•	insurance companies;

	•	broker dealers;

	•	U.S. expatriates

	•	traders that elect to mark to market;

	•	tax-exempt entities;

120


	•	persons liable for alternative minimum tax;

	•	persons holding a common share as part of a straddle, hedging, conversion or integrated transaction;

	•	persons that actually or constructively own 10.0% or more of our voting stock;

	•	persons who acquired common shares pursuant to the exercise of any employee share option or otherwise as consideration; or

	•	persons holding common shares through partnerships or other pass-through entities.

PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR TAX ADVISORS ABOUT THE APPLICATION OF THE U.S. FEDERAL TAX RULES TO THEIR PARTICULAR CIRCUMSTANCES AS WELL AS THE STATE AND LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF COMMON SHARES.

The discussion below of the U.S. federal income tax consequences to “U.S. Holders” will apply if you are a beneficial owner of common shares and you are, for U.S. federal income tax purposes,


	•	an individual who is a citizen or resident of the United States;

	•	a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) organized under the laws of the United States, any State or the District of Columbia;

	•	an estate whose income is subject to U.S. federal income taxation regardless of its source; or

	•	a trust that (1) is subject to the supervision of a court within the United States and the control of one or more U.S. persons or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

If you are a partner in partnership or other entity taxable as a partnership that holds common shares, your tax treatment will depend on your status and the activities of the partnership.

Taxation of Dividends and Other Distributions on the Common shares

Subject to the passive foreign investment company rules discussed below, the gross amount of all our distributions to you with respect to the common shares (including any Canadian Taxes withheld therefrom) will be included in your gross income as foreign source ordinary dividend income on the date of receipt by you, but only to the extent that the distribution is paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). To the extent that the amount of the distribution exceeds our current and accumulated earnings and profits, it will be treated first as a tax-free return of your tax basis in your common shares, and to the extent the amount of the distribution exceeds your tax basis, the excess will be taxed as capital gain. We do not intend to calculate our earnings and profits under U.S. federal income tax principles. Therefore, a U.S. Holder should expect that a distribution will be treated as a dividend. The dividends will not be eligible for the dividends-received deduction allowed to corporations in respect of dividends received from other U.S. corporations.

With respect to non-corporate U.S. Holders including individual U.S. Holders, for taxable years beginning before January 1, 2011, dividends may constitute “qualified dividend income” that is taxed at the lower applicable capital gains rate provided that (1) the common shares are readily tradable on an established securities market in the United States, (2) we are not a passive foreign investment company (as discussed below) for either our taxable year in which the dividend was paid or the preceding taxable year, (3) certain holding period requirements are met and (4) you are not under an obligation to make related payments with respect to positions in substantially similar or related property. Under Internal Revenue Service authority, common shares are considered for the purpose of clause (1) above to be readily tradable on an established securities market in the United States if they are listed on the Nasdaq Global Market, as our common shares

121

are expected to be. You should consult your tax advisors regarding the availability of the lower rate for dividends paid with respect to our common shares.

Subject to certain limitations, Canadian taxes withheld from a distribution will be eligible for credit against your U.S. federal income tax liability. If a refund of the tax withheld is available to you under the laws of Canada or under the Canada-United States Income Tax Convention (1980), the amount of tax withheld that is refundable will not be eligible for such credit against your U.S. federal income tax liability (and will not be eligible for the deduction against your U.S. federal taxable income). If the dividends are qualified dividend income (as discussed above), the amount of the dividend taken into account for purposes of calculating the foreign tax credit limitation will in general be limited to the gross amount of the dividend, multiplied by the reduced rate divided by the highest rate of tax normally applicable to dividends. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividends distributed by us with respect to common shares should constitute “passive income.” For taxable years beginning after December 31, 2006, dividends distributed by us with respect to common shares generally will constitute “passive category income” but could, in the case of certain U.S. Holders, constitute “general category income.” The rules relating to the determination of the U.S. foreign tax credit are complex and U.S. Holders should consult their tax advisors to determine whether and to what extent a credit would be available. If you do not elect to claim a foreign tax credit with respect to any foreign taxes for a given taxable year, you may instead claim an itemized deduction for all foreign taxes paid in that taxable year.

Taxation of Disposition of Shares

Subject to the passive foreign investment company rules discussed below, you will recognize taxable gain or loss on any sale, exchange or other taxable disposition of a common share equal to the difference between the amount realized for the common share and your tax basis in the common share. The gain or loss will be capital gain or loss. If you are a non-corporate U.S. Holder, including an individual U.S. Holder, who has held the common share for more than one year, you will be eligible for reduced tax rates. The deductibility of capital losses is subject to limitations. Any such gain or loss that you recognize will be treated as U.S. source income or loss for foreign tax credit limitation purposes, subject to certain exceptions and limitations.

Passive Foreign Investment Company

We do not expect to be a passive foreign investment company (“PFIC”), for U.S. federal income tax purposes for our current taxable year ending December 31, 2006, and we expect to operate in such a manner so as not to become a PFIC in future taxable years. Our expectation for our current taxable year is based in part on our estimates of the value of our assets as determined based on the price of our common shares in this offering and the expected price of our common shares following the offering. However, our actual PFIC status for any taxable year will not be determinable until the close of such year, and, accordingly, there is no guarantee that we will not be a PFIC for the current taxable year or any future taxable year. A non-U.S. corporation is considered to be a PFIC for any taxable year if either:


	•	at least 75% of its gross income is passive income (the “income test”), or

	•	at least 50% of the value of its assets (based on an average of the quarterly values of the assets during a taxable year) is attributable to assets that produce or are held for the production of passive income (the “asset test”).

We will be treated as owning our proportionate share of the assets and earning our proportionate share of the income of any other corporation in which we own, directly or indirectly, more than 25% (by value) of the stock.

We must make a separate determination each year as to whether we are a PFIC. As a result, our PFIC status may change. In particular, because the total value of our assets for purposes of the asset test will be calculated using the market price of our common shares (assuming that we are a publicly traded corporation

122

for purposes of the applicable PFIC rules), our PFIC status will depend in large part on the market price of our common shares which is likely to fluctuate after the offering (and may fluctuate considerably given that market prices of technology companies have been especially volatile). Accordingly, fluctuations in the market price of our common shares may result in our being a PFIC for any year. In addition, the composition of our income and assets will be affected by how, and how quickly, we spend the cash we raise in this offering. If we are a PFIC for any year during which you hold common shares, we will continue to be treated as a PFIC for all succeeding years during which you hold common shares unless we cease to be a PFIC and you take certain action to purge the PFIC taint with respect to your common shares. In particular, if we cease to be a PFIC, you may avoid some of the adverse effects of the PFIC regime by making a deemed sale election with respect to the common shares.

If we are a PFIC for any taxable year during which you hold common shares, you will be subject to special tax rules with respect to any “excess distribution” that you receive and any gain you realize from a sale or other disposition (including a pledge) of the common shares, unless you make a “mark-to-market” election as discussed below. Distributions you receive in a taxable year that are greater than 125% of the average annual distributions you received during the shorter of the three preceding taxable years or your holding period for the common shares will be treated as an excess distribution. Under these special tax rules:


	•	the excess distribution or gain will be allocated ratably over your holding period for the common shares,

	•	the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we became a PFIC, will be treated as ordinary income, and

	•	the amount allocated to each other year will be subject to the highest tax rate in effect for that year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such year.

The tax liability for amounts allocated to years prior to the year of disposition or “excess distribution” cannot be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the common shares cannot be treated as capital, even if you hold the common shares as capital assets.

We do not intend to prepare or provide the information that would enable you to make a qualified electing fund election.

Alternatively, a U.S. Holder of “marketable stock” (as defined below) in a PFIC may make a mark-to-market election with respect to shares of a PFIC to elect out of the tax treatment discussed above. If you make a valid mark-to-market election for the common shares, you will include in income each year an amount equal to the excess, if any, of the fair market value of the common shares as of the close of your taxable year over your adjusted basis in such common shares. You are allowed a deduction for the excess, if any, of the adjusted basis of the common shares over their fair market value as of the close of the taxable year. However, deductions are allowable only to the extent of any net mark-to-market gains on the common shares included in your income for prior taxable years. Amounts included in your income under a mark-to-market election, as well as gain on the actual sale or other disposition of the common shares, are treated as ordinary income. Ordinary loss treatment also applies to the deductible portion of any mark-to-market loss on the common shares, as well as to any loss realized on the actual sale or disposition of the common shares, to the extent that the amount of such loss does not exceed the net mark-to-market gains previously included for such common shares. Your basis in the common shares will be adjusted to reflect any such income or loss amounts. If you make such an election, the tax rules that ordinarily apply to distributions by corporations that are not PFICs would apply to distributions by us, except that the lower applicable gains rate would not apply.

The mark-to-market election is available only for “marketable stock,” which is stock that is traded in other than de minimis quantities on at least 15 days during each calendar quarter on a qualified exchange, including the Nasdaq Global Market, or other market, as defined in applicable U.S. Treasury regulations. We expect that our common shares will be listed on the Nasdaq Global Market and, consequently, if you are a holder of common shares the mark-to-market election would be available to you were we to be a PFIC.

123

If you hold common shares in any year in which we are a PFIC, you will be required to file Internal Revenue Service Form 8621 regarding distributions received on the common shares and any gain realized on the disposition of the common shares.

You are urged to consult your tax advisor regarding the application of the PFIC rules to your investment in common shares.

Estate Tax

An individual shareholder or resident of the United States for U.S. federal estate tax purposes will have the value of the common shares held by such holder included in his or her gross estate for U.S. federal estate tax purposes. An individual holder who actually pays estate tax with respect to the common shares will, however, be entitled to credit the amount of such tax against his or her U.S. federal tax liability, subject to a number of conditions and limitations.

Information Reporting and Backup Withholding

Dividend payments with respect to common shares and proceeds from the sale, exchange or redemption of common shares may be subject to information reporting to the Internal Revenue Service and possible U.S. backup withholding at a current rate of 28%. Backup withholding will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes any other required certification or who is otherwise exempt from backup withholding. U.S. Holders who are required to establish their exempt status may provide such certification on Internal Revenue Service Form W-9. U.S. Holders should consult their tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against your U.S. federal income tax liability, and you may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the Internal Revenue Service and furnishing any required information.

124

In addition, in respect of ATS, the foregoing restrictions will not apply to (i) transfers to ATS’s affiliates or to Photowatt Technologies Inc. or its affiliates, (ii) any of our common shares acquired in the open market or (iii) participation in any tender offer involving our common shares. In addition, in the case of Shawn (Xiaohua) Qu, the foregoing restrictions will not apply to pre-existing pledges of common shares as of the date of this prospectus as disclosed in the prospectus relating to this offering, and any enforcement of such pledges.

The 180-day restricted period described in the preceding paragraph will be extended if (i) during the last 17 days of the 180-day restricted period, we issue an earnings release or material news or a material event relating to us occurs or (ii) prior to the expiration of the 180-day restricted period, we announce that we will release earnings results during the 16-day period beginning on the last day of the 180-day period, in which case the restrictions described in the preceding paragraph will continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release, the announcement of the material news or the occurrence of a material event, unless such extension is waived by Deutsche Bank Securities Inc. and Lehman Brothers Inc.

Deutsche Bank Securities Inc. and Lehman Brothers Inc., in their sole discretion, may release the common shares and other securities subject to the lock-up agreements described above in whole or in part at any time with our without notice. When determining whether or not to release the common shares or other securities from the lock-up agreements, Deutsche Bank Securities Inc. and Lehman Brothers Inc. will consider, among other factors, the holder’s reasons for requesting the release, the number of common shares or other securities for which the release is being requested and market conditions at the time.

Offering Price Determination

Prior to this offering, there has been no public market for our common shares. The initial public offering price will be negotiated between the representatives and us and the selling shareholders. In determining the initial public offering price of our common shares, the representatives will consider:


	•	the history and prospects for the industry in which we compete;

	•	our financial information;

126


	•	the ability of our management and our business potential and earning prospects;

	•	the prevailing securities markets at the time of this offering; and

	•	the recent market prices of, and the demand for, publicly traded shares of generally comparable companies.

Indemnification

We and the selling shareholders have agreed to indemnify the underwriters against liabilities relating to the offering, including liabilities under the Securities Act and liabilities incurred in connection with the directed share program referred to below, and to contribute to payments that the underwriters may be required to make for these liabilities.

Stabilization, Short Positions and Penalty Bids

The representatives may engage in stabilizing transactions, short sales and purchases to cover positions created by short sales, and penalty bids or purchases for the purpose of pegging, fixing or maintaining the price of our common shares, in accordance with Regulation M under the Exchange Act of 1934:


	•	Stabilizing transactions permit bids to purchase common shares so long as the stabilizing bids do not exceed a specified maximum.

	•	A short position involves a sale by the underwriters of common in excess of the number of common shares the underwriters are obligated to purchase in the offering, which creates the syndicate short position. This short position may be either a covered short position or a naked short position. In a covered short position, the number of common shares involved in the sales made by the underwriters in excess of the numbers of common shares they are obligated to purchase is not greater than the number of common shares that they may purchase by exercising their option to purchase additional shares. In a naked short position, the number of common shares involved is greater than the number of common shares in their option to purchase additional shares. The underwriters may close out any short position by either exercising their option to purchase additional shares and/or purchasing common shares in the open market. In determining the source of common shares to close out the short position, the underwriters will consider, among other things, the price of common shares available for purchase in the open market as compared to the price at which they may purchase common shares through their option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the common shares in the open market after pricing that could adversely affect investors who purchase in the offering.

	•	Syndicate covering transactions involve purchases of our common shares in the open market after the distribution has been completed in order to cover syndicate short positions.

	•	Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the common shares originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common shares or preventing or retarding a decline in the market price of our common shares. As a result, the price of common shares may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the Nasdaq Global Market or otherwise and, if commenced, may be discontinued at any time.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common shares. In addition, neither we nor any of the underwriters make any representation that the representatives will

127

engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

Stamp Taxes

If you purchase the common shares offered in this prospectus, you may be required to pay stamp taxes and other charges under the laws and practices of the country of purchase, in addition to the offering price listed on the cover page of this prospectus.

Directed Share Program

At our request, the underwriters have reserved for sale at the initial public offering price up to 385,000 common shares offered hereby for officers, directors, employees and certain other persons associated with us. The number of common shares available for sale to the general public will be reduced to the extent such persons purchase such reserved common shares. Any reserved common shares not so purchased will be offered by the underwriters to the general public on the same basis as the other common shares offered hereby.

Electronic Distribution

A prospectus in electronic format may be made available on the Internet sites or through other online services maintained by one or more of the underwriters and/or selling group members participating in this offering, or by their affiliates. In those cases, prospective investors may view offering terms online and, depending upon the particular underwriter or selling group member, prospective investors may be allowed to place orders online. The underwriters may agree with us to allocate a specific number of common shares for sale to online brokerage account holders. Any such allocation for online distributions will be made by the representatives on the same basis as other allocations.

Other than the prospectus in electronic format, the information or any underwriter’s website and any information contained in any other web site maintained by an underwriter or selling group member is not part of this prospectus or the registration statement of which this prospectus forms a part, has not been approved and/or endorsed by us or any underwriter or selling group member in its capacity as underwriter or selling group member and should not be relied on by investors in deciding whether to purchase any common shares.

Nasdaq Global Market

Our common shares have been approved for listing on the Nasdaq Global Market under the symbol “CSIQ.”

Discretionary Sales

The underwriters have informed us that they do not intend to confirm sales to accounts over which they exercise discretionary authority in excess of 5% of the total number of common shares offered by them.

Relationships

The underwriters have performed and may in the future perform investment banking and advisory services for us from time to time for which they have received or may in the future receive customary fees and expenses. The underwriters may, from time to time, engage in transactions with or perform services for us in the ordinary course of their business.

Foreign Securities Laws Restrictions

The common shares have not been and will not be qualified for sale to the public under applicable Canadian securities laws. The common shares may not be offered or sold, and the underwriters have agreed not to offer or sell the common shares, directly or indirectly, in Canada or to or for the benefit of any person in Canada, except in compliance with applicable Canadian securities laws.

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive, with effect from and including the date on which the Prospectus Directive is implemented in that Member State the underwriters have not made and may not make an offer of common shares to the public in that Member State, except that the underwriters may, with effect from and including such date, make an offer of common shares to the public in that Member State:

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholder of

Canadian Solar Inc.:

We have audited the accompanying consolidated balance sheets of Canadian Solar Inc. and its subsidiaries (the “Company”) as of December 31, 2003, 2004 and 2005 and June 30, 2006, and the related consolidated statements of operations, stockholder’s equity and comprehensive income, and cash flows for each of the three years in the period ended December 31, 2005, and the six-month period ended June 30, 2006, and related financial schedule included in Schedule 1. These financial statements and related financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and related financial statement schedule based on our audits.

We conducted our audits 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. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also 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, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2003, 2004 and 2005 and June 30, 2006 and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2005 and the six-month period ended June 30, 2006 in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly in all respects, the information set forth therein.

CANADIAN SOLAR INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2003, 2004 AND 2005 AND THE

SIX-MONTH PERIODS ENDED JUNE 30, 2005 (UNAUDITED) AND 2006

(In U.S. dollars)


1.	ORGANIZATION AND PRINCIPAL ACTIVITIES

Canadian Solar Inc. (“CSI”) was incorporated in Canada under the laws of the province of Ontario, Canada on October 22, 2001 and was continued under the federal laws of Canada in June 2006.

CSI and its subsidiaries (collectively, the “Company”) are principally engaged in the design, development, manufacturing and marketing of solar power products for global markets. During the periods covered by the consolidated financial statements, substantially all of the Company’s business was conducted through both CSI and operating subsidiaries established in the PRC, CSI Solartronics (Changshu) Co., Ltd. (“CSI Changshu”), CSI Solar Technologies Inc., CSI Solar Manufacture Inc. (“CSI Manufacture”), CSI Solarchip International Co., Ltd. (“CSI Solarchip”) and CSI Solar Power Central Ltd., (“CSI Luoyang”), in each of which CSI holds 100% interest.


2.	SUMMARY OF PRINCIPAL ACCOUNTING POLICIES

(a) Basis of presentation

The financial statements of the Company have been prepared in accordance with the accounting principles generally accepted in the United States of America (“US GAAP”).

(b) Basis of Consolidation

The consolidated financial statements include the financial statements of CSI and its majority-owned subsidiaries. All significant intercompany transactions and balances are eliminated on consolidation.

(c) Use of estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant accounting estimates reflected in the Company’s financial statements include allowance for doubtful debts, allowance for inventory obsolescence, accrual for warranty, valuation of deferred tax assets, and useful lives of property, plant and equipment.

(d) Cash and cash equivalents

Cash and cash equivalents consist of cash on hand and demand deposits, which are unrestricted as to withdrawal and use, and which have maturities of three months or less when purchased.

Restricted cash represented bank deposits for import and export transactions through China Customs and for bank acceptances notes.

(e) Inventories

Inventories are stated at the lower of cost or market. Cost is determined by the weighted average method. Cost comprises direct materials and where applicable, direct labor costs, tolling costs and those overheads that have been incurred in bringing the inventories to their present location and condition.

Adjustments are recorded to write down the cost of obsolete and excess inventory to the estimated market value based on historical and forecast demand.

F-7

The Company outsources portions of its manufacturing process, including converting silicon into ingots, cutting ingots into wafers, and converting wafers into solar cells, to various third-party manufacturers. These outsourcing arrangements may or may not include transfer of title of the raw material inventory (silicon, ingots or wafers) to the third-party manufacturers. Such raw materials are recorded as raw materials inventory when purchased from suppliers. For those outsourcing arrangements in which title is not transferred, the Company maintains such inventory on the Company’s balance sheet as raw materials inventory while it is in physical possession of the third-party manufacturer. Upon receipt of the processed inventory, it is reclassified to work-in-process inventory and a processing fee is paid to the third-party manufacturer. For those outsourcing arrangements, which are characterized as sales, in which title (including risk of loss) does transfer to the third-party manufacturer, the Company is constructively obligated, through raw materials sales agreements and processed inventory purchase agreements which have been entered into simultaneously with the third-party manufacturer, to repurchase the inventory once processed. In this case, the raw material inventory remains classified as raw material inventory while in the physical possession of the third-party manufacturer and cash is received which is classified as “advances from suppliers and customers” on the balance sheet and not as revenue or deferred revenue. Cash payments for outsourcing arrangements which require prepayment for repurchase of the processed inventory is classified as “advances to suppliers” on the balance sheet. There is no right of offset for these arrangements and accordingly, “advances from suppliers and customers” and “advances to suppliers” remain on the balance sheet until the processed inventory is repurchased.

(f) Property, plant and equipment

Property, plant and equipment are recorded at cost less accumulated depreciation and amortization. Depreciation and amortization are provided on a straight-line basis over the following estimated useful lives:


Leasehold improvements		Over the shorter of the lease term or their estimated useful lives
Plant and machinery		10 years
Furniture, fixtures and equipment		5 years
Motor vehicles		5 years

Cost incurred in constructing new facilities, including progress payment and other costs relating to the construction, are capitalized and transferred to property, plant and equipment on completion and depreciation commences from that time.

(g) Impairment of long-lived assets

The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When these events occur, the Company measures impairment by comparing the carrying amount of the assets to future undiscounted net cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, the Company would recognize an impairment loss based on the fair value of the assets.

(h) Income taxes

Deferred income taxes are recognized for temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, net operating loss carry forwards and credits by applying enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of the relevant taxing authorities. The components of the deferred tax assets and liabilities are individually classified as current and non-current based on the characteristics of the underlying assets and liabilities.

F-8

(i) Revenue recognition

Sales of modules are recorded when products are delivered and title has passed to the customers. The Company only recognizes revenues when prices to the seller are fixed or determinable, and collectibility is reasonably assured. Revenues also include reimbursements of shipping and handling costs of products sold to customers. Sales agreements typically contain the customary product warranties but do not contain any post-shipment obligations nor any return or credit provisions.

A majority of the Company’s contracts provide that products are shipped under the term of free on board (“FOB”), Ex-works, or cost, insurance and freight (“CIF”). Under FOB, the Company fulfils its obligation to deliver when the goods have passed over the ship’s rail at the named port of shipment. The customer has to bear all costs and risks of loss or damage to the goods from that point. Under Ex-works, the Company fulfils its obligation to deliver when it has made the goods available at its premises to the customer. The customer bears all costs and risks involved in taking the goods from the Company’s premises to the desired destination. Under CIF, the Company must pay the costs, marine insurance and freight necessary to bring the goods to the named port of destination but the risk of loss of or damage to the goods, as well as any additional costs due to events occurring after the time the goods have been delivered on board the vessel, is transferred to the customer when the goods pass the ship’s rail in the port of shipment. Most of the Company’s sales require that customers prepay before delivery has occurred. Such prepayments are recorded as advances from customers until delivery is made. The sales agreements usually contain the Company’s customary product warranties but do not contain any post-shipment obligations nor any return or credit provisions.

The Company also generates revenues from its implementation of solar development projects, consisting primarily of government-related assistance packages for its demonstration, promotion and feasibility projects and studies. The revenue is recognized when the projects are provided and accepted by the customers.

(j) Cost of revenue

Cost of revenue from modules includes production and indirect costs such as shipping and handling costs for products sold. Cost of revenue from solar development projects mainly includes labor costs and material costs associated with the projects.

(k) Research and development

Research and development costs are expensed when incurred.

(l) Advertising expenses

Advertising expenses are charged to the income statements in the period incurred. The Company incurred advertising expenses amounting to $nil, $nil, $6,034 and $25,337 for the years ended December 31, 2003, 2004, 2005 and six-month period ended June 30, 2006, respectively.

(m) Warranty cost

The Company’s solar modules and products are typically sold with up to a two-year guarantee for defects in materials and workmanship and 10-year and 25-year warranties against specified declines in the initial minimum power generation capacity at the time of delivery. The Company has the right to repair or replace solar modules, at its option and based on the specific nature of the defect claims under a warranty claim, under the terms of the warranty policy. We maintain warranty reserves to cover potential liabilities that could arise under these guarantees and warranties. Due to limited warranty claims to date, we accrue the estimated costs of warranties based on an assessment of our competitors’ accrual history, industry-standard accelerated testing, estimates of failure rates from our quality review, and other assumptions that we believe to be reasonable under the circumstances. The Company currently accrues the equivalent of 1% of solar module sales revenues as warranty reserves to cover the guarantees and warranties. Actual warranty costs are

F-9

accumulated and charged against the accrued warranty liability. To the extent that accrual warranty costs differ from the estimates, the Company will prospectively revise its accrual rate.

(n) Foreign currency translation

The United States dollar (“U.S. dollar”), the currency in which substantial amount of the Company’s transactions are denominated, is used as the functional and reporting currency of CSI. Monetary assets and liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollar at the rates of exchange ruling at the balance sheet date. Transactions in currencies other than the U.S. dollar during the year are converted into the U.S. dollar at the applicable rates of exchange prevailing on the day transactions occurred. Transaction gains and losses are recognized in the statements of income. The aggregated amount of exchange gain (loss) is $(8,721), $230,960 and $(106,059) and $(76,162) for the years ended December 31, 2003, 2004, 2005 and six-month period ended June 30, 2006, respectively.

The financial records of certain of the Company’s subsidiaries are maintained in local currencies other than the U.S. dollar, such as Renminbi (“RMB”), which are their functional currencies. Assets and liabilities are translated at the exchange rates at the balance sheet date, equity accounts are translated at historical exchange rates and revenues, expenses, gains and losses are translated using the average rate for the year. Translation adjustments are reported as foreign currency translation adjustment and are shown as a separate component of other comprehensive income (loss) in the statement of stockholder’s equity.

(o) Foreign currency risk

The RMB is not a freely convertible currency. The PRC State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of RMB into foreign currencies. The value of the RMB is subject to changes in central government policies and to international economic and political developments affecting supply and demand in the China foreign exchange trading system market. The Company’s cash and cash equivalents and restricted cash dominated in RMB amounted to $156,776, $173,205, $644,753 and $1,459,454 at December 31, 2003, 2004, 2005 and June 30, 2006, respectively.

(p) Concentration of credit risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, accounts receivable and advance to suppliers. The Company places its cash and cash equivalents with reputable financial institutions.

The Company conducts credit evaluations of customers and generally does not require collateral or other security from its customers. The Company establishes an allowance for doubtful accounts primarily based upon the age of the receivables and factors surrounding the credit risk of specific customers. With respect to advances to suppliers, such suppliers are primarily suppliers of raw materials. The Company performs ongoing credit evaluations of its suppliers’ financial conditions. The Company generally does not require collateral or the security against advance to suppliers, however, it maintains reserve for potential credit losses and such losses have historically been within management’s expectation.

(q) Fair value of derivatives and financial instruments

The carrying amounts of trade receivables, trade payables, short-term borrowings and accrued payroll and welfare approximate their fair values due to the short-term maturity of these instruments.

Because the Company’s convertible notes and common stock are not publicly traded the Company has relied solely on valuation models in determining these values. The valuation models include assumptions regarding discount rates, market multiples, lack of marketability discounts, and other assumptions that are highly subjective and judgmental. Changes to any of the assumptions used in the valuation model could materially impact the valuation results.

F-10

(r) Beneficial conversion feature

When the Company issues debt or equity which is convertible into common stock at a discount from the common stock market or fair value price at the date the debt or equity is issued, a beneficial conversion feature for the difference between the fair value price and the conversion price multiplied by the number of shares issuable upon conversion is recognized. The beneficial conversion feature is presented as a discount to the related debt or equity, with an offsetting amount increasing additional paid-in capital. The discount resulting from recording a beneficial conversion option is accreted for the date of issuance to the stated redemption date of the convertible instrument.

(s) Extraordinary gain

From March 2002 to December 2003, the Company held 68.1% interests of CSI Changshu and two Chinese companies held 31.9% interests. The Company bought out this minority interests of 31.9% in CSI Changshu at the end of 2003. The acquisitions were recorded using the purchase method of accounting and, accordingly, the acquired assets and liabilities were recorded at their fair value at the date of acquisition. Since the fair value of the consideration of $331,006 in form of cash and products is less than the fair value of the acquired net assets, an excess fair value of acquired net assets over cost is derived. That excess is allocated as a pro rata reduction of the amounts that otherwise would have been assigned to all of the acquired assets except financial assets other than investments accounted for by the equity method, assets to be disposed of by sale, deferred tax assets, prepaid assets relating to pension or other postretirement benefit plans, and any other current assets. Any remaining excess is recognized as an extraordinary gain.

(t) Earnings per Share

Basic income per share is computed by dividing income attributable to holders of common shares by the weighted average number of common shares outstanding during the year. Diluted income per common share reflects the potential dilution that could occur if securities or other contracts to issue common shares were exercised or converted into common shares.

(u) Recently issued accounting pronouncements

In November 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 151, “Inventory Costs — an amendment of ARB No. 43, Chapter 4”. SFAS No. 151 clarifies the accounting that requires abnormal amounts of idle facility expenses, freight, handling costs, and spoilage costs to be recognized as current-period charges. It also requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS No. 151 will be effective for inventory costs incurred in fiscal period beginning on or after June 15, 2005. The Company does not anticipate that the adoption of this statement will have a material effect on the Company’s financial position, cash flow or results of operations.

In December 2004, the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets — an amendment of APB Opinion No. 29” (“SFAS 153”), which amends Accounting Principles Board Opinion No. 29, “Accounting for Nonmonetary Transactions” to eliminate the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. SFAS 153 is effective for nonmonetary assets exchanges occurring in fiscal periods beginning after June 15, 2005. The Company does not anticipate that the adoption of this statement will have a material effect on the Company’s financial position, cash flow or results of operations.

In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections” (“SFAS 154”) which replaces Accounting Principles Board Opinions No. 20 “Accounting Changes” and SFAS No. 3, “Reporting Accounting Changes in Interim Financial Statements — An Amendment of APB Opinion No. 28.” SFAS 154 provides guidance on the accounting for and reporting of accounting changes and error corrections. It establishes retrospective application, or the latest practicable date, as the required method for reporting a change in accounting principle and the reporting of a correction of an error. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after

F-11

December 15, 2005. The Company does not anticipate that the adoption of this statement will have a material effect on the Company’s financial position, cash flow or results of operations.

In December 2004, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (“SFAS 123R”). SFAS 123R eliminates the alternative of applying the intrinsic value measurement provisions of APB 25 to stock compensation awards issued to employees. Rather, SFAS 123R requires enterprises to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost will be recognized over the period during which an employee is required to provide services in exchange for the award, known as the requisite service period (usually the vesting period). As of December 31, 2005 no stock options had been issued.

In March 2005, the FASB issued FASB Interpretation No.(“FIN”) 47, “Accounting for Conditional Assets Retirement Obligations, an interpretation of SFAS No. 143”. FIN 47 clarifies that an entity is required to recognize a liability for legal obligation to perform an asset retirement activity if the fair value can be reasonably estimated even though the timing and/or method of settlement are conditional on a future event. FIN 47 is required to be adopted for annual reporting periods ending after December 15, 2005. The Company does not anticipate that the adoption of this statement will have a material effect on the Company’s financial position, cash flow or results of operations.

In September 2005 the FASB approved EITF Issue 05-07, “Accounting for Modifications to Conversion Options Embedded in Debt Securities and Related Issues” (“EITF 05-07”). EITF 05-07 requires the change in the fair value of an embedded conversion option upon modification be included in the analysis under EITF Issue 96-16, “Debtor’s Accounting for a Modification or Exchange of Debt Instruments,” to determine whether a modification or extinguishment has occurred and that the changes to the fair value of a conversion option affects the interest expense on the associated debt instrument following a modification. Therefore, the change in fair value of the conversion option should be recognized upon the modification as a discount or premium associated with the debt, and an increase or decrease in additional paid-in capital. EITF Issue 05-07 is effective for all debt modifications in annual or interim periods beginning after December 31, 2005. The adoption of EITF 05-07 did not have an impact on the Company’s financial position and results of operations.

In June 2006 the FASB released Interpretation No.48, Accounting for Uncertainty in Income Taxes-an Interpretation of FASB Statement No.109, (‘FIN 48‘) which proscribes a recognition threshold and a measurement attribute for tax positions taken, or expected to be taken, in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006, with early adoption encouraged if the enterprise has not yet issued financial statements for fiscal years or interim periods in the period this Interpretation is adopted. The Company does not anticipate that the adoption of this statement will have a material effect on the Company’s financial position, cash flow or results of operations.

(v) Pro Forma Information

The pro forma unaudited balance sheet information as of June 30, 2006 assumes the conversion upon completion of the initial public offering of all convertible notes outstanding as of June 30, 2006 into common shares.

(v) Pro Forma Earnings Per Share

The pro forma unaudited basic and diluted earnings per common share is computed by dividing net income by the weighted average number of common shares outstanding for the period plus the number of common shares resulting from the assumed conversion upon completion of the initial public offering of all convertible notes outstanding.

F-12

(w) Stock-based compensation

The Company grants stock options to its employees and certain non-employees. The Company records stock-based compensation for services rendered using the Black-Scholes option pricing model.

8.	CONVERTIBLE NOTES

On November 30, 2005, the Company signed a subscription agreement with a group of third-party investors to issue two tranches of convertible notes. The first tranche of notes with a principal value of $8,100,000 was issued on November 30, 2005. The second tranche of notes with a principal value of $3,650,000 was issued on March 30, 2006.

The terms of the convertible notes are described as follows:

Maturity date. The convertible notes mature on November 30, 2008.

Interest. The note holders are entitled to receive interest at 2% per annum on the principal outstanding, in four equal quarterly installments in arrears.

If the Company fails to pay any principal or interest amounts, or other payments in respect of the notes, when due, or if the convertible notes are not converted in full into common shares on the date requested by the note holders, the convertible notes shall bear an extraordinary interest, compounded at a rate of twelve percent (12%) per annum for any amounts of overdue principal, interest or other payment under the convertible notes.

If the Company has not completed a qualified initial public offering (defined as (i) an offering size of not less than $30,000,000, (ii) total market capitalization of not less than $120,000,000, and (iii) public float of not less than twenty-five percent (25%) of the enlarged share capital) prior to maturity of the convertible notes, the Company must pay an interest premium of ten percent (10%) per annum in respect of principal, paid and unpaid interest, unpaid dividends, and extraordinary interest.

The Company is recognizing interest expense using the effective interest method for the 2% per annum quarterly payments and 10% per annum due at the maturity date in the event that a qualified initial public offering has not occurred.

Witholding Taxes All payments in respect of the note will be made without withholding or deduction of or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of the government of Hong Kong, Canada or any authority therein or thereof having power to tax unless the withholding or deduction of such taxes, duties, assessments or governmental charges is required by law.

Dividends. The stockholder as of the issue date is entitled to all audited retained earnings as of 28 February 2006. The Company shall not declare or pay any dividend before the completion of a qualified initial public offering or redemption of all convertible notes, except with the prior written consent of all holders of the outstanding convertible notes.

Conversion. The notes are convertible into 5,542,005 common shares at a conversion rate of $2.12 per share. The fair value of the Company’s common stock on November 30, 2005 was $2.43 per share.

F-14

The notes are convertible (i) at any time after the date of issuance of such notes upon obtaining written consents from the note holders requesting conversion to common shares, and (ii) automatically upon the consummation of a qualified initial public offering. The conversion rate is subject to standard anti-dilutive adjustments and is also subject to adjustment in the event that (i) the Company’s audited profit after tax for the twelve month period ended February 28, 2006 is less than certain predefined amounts, (ii) the Company’s number of shares issued or issuable on a fully diluted basis is different from a predefined quantity at conversion, or (iii) the Company issues equity securities at a price below the conversion price then in effect. At November 30, 2005 the Company was required to bifurcate the conversion feature pursuant to FASB Statement No. 133, Accounting for Derivative Instruments and Hedging Activities (“SFAS 133”).

Redemption. If the Company experiences an event of default under the subscription agreement (including but not limited to a change of control of the Company) prior to maturity and upon written demand from the note holders (referred to as “early redemption right”), the Company must pay the greater of (i) an interest premium of twelve percent (12%) per annum in respect of principal, paid and unpaid interest, unpaid dividends, and extraordinary interest, or (ii) the fair value of the Company’s common shares that would be held by the note holders on an if-converted basis. The Company was required to bifurcate the early redemption right pursuant to FASB 133.

Liquidation preference. The convertible notes are senior to any common shareholder claims in the event of liquidation.

Registration Rights Agreement. Anytime 6 months after a successful IPO, upon the demand by at least 25% of the holders of the Company’s common shares related to the convertible notes, the Company must initiate a registration statement to register the shares held by the previous note holders. The Company must initiate such a registration statement within 120 days of the demand by the shareholders. The registration rights agreement contains no penalties in the event the Company is unable to initiate such a registration statement in the period prescribed.

The $8,100,000 purchase price of convertible notes issued on November 30, 2005 was reduced by issuance costs of $641,000. The Company allocated $3,363,000 of the net proceeds of $7,459,000 to the compound embedded derivative liability which was comprised of the bifurcated conversion feature and the early redemption right, $843,996 to the freestanding financial instruments liability associated with the obligation to issue the second tranche of convertible debt to the investors and the investors’ option to subscribe for a third tranche of convertible debt, and $3,252,004 to the convertible debt. The resulting discount on the convertible debt is being amortized over the three year term using the straight-line method which approximates the effective interest rate method.

As of December 31, 2005, the fair values of the convertible debt, compound embedded derivative liability, the freestanding financial instrument liability were $11,595,000, $3,679,000, and $1,606,500, respectively. Changes in the fair value of the compound embedded derivative and the freestanding option, which is classified within the freestanding financial liability, are recognized at each reporting date and are classified as loss on change in value of derivatives in the statements of operations.

Subsequent to the November 30, 2005 issuance the Company and the note holders amended the terms of the note agreement as follows:


	•	On March 30, 2006, the Company and the note holders executed a supplemental agreement amending certain provisions related to events of default prior to conversion or maturity (as defined in the subscription agreement). The original terms required that, in the event of default, the Company pay the note holders the greater of a 12% interest premium or the fair value of the common stock underlying the convertible notes on an if-converted basis. The terms of the supplemental agreement state that in an event of default the Company must pay an interest premium of 18%. The terms of the original agreement created a provision which allowed for potential net settlement of the Company’s common shares, and accordingly, prior to the supplemental agreement, the Company was required to bifurcate the conversion option from the host debt instrument as it met the test of a derivative instrument. Since the

F-15


		supplemental agreement removed the net settlement provision the Company was no longer required to bifurcate the conversion option. Accordingly, on March 30, 2006, the Company derecognized the embedded derivative liability related to the conversion option. Because the early redemption put option continues to meet the definition of a derivative instrument after the March 30, 2006 modification, the early redemption option continues to be recorded by the Company as a derivative liability and reported at its fair value with changes in its fair value recognized in the statements of operations. The early redemption option was valued by an independent valuation using the Black-Scholes option pricing model.

	•	In addition to revising the provisions related to events of default, the March 30, 2006 supplemental agreement revised the original subscription agreement to revise the profit after tax computation to exclude all costs and charges related to the issuance of the convertible notes, including all costs and charges related to the recording of the derivative and freestanding financial instruments associated with the convertible notes, including changes to their fair values. The supplemental agreement effectively requires that the Company achieve a profit after tax of $6 million for the 12-month period ended February 28, 2006, reduced by the amount of all costs and charges related to the issuance of the convertible notes and related derivative and freestanding financial instruments.


		Additionally, the supplemental agreement revised the requirement under the original subscription agreement that the Company deliver to the note holders audited financial statements for the year ended December 31, 2004 of profit after tax of $1 million, and the eight-month period ended August 31, 2005 of profit after tax of $4.5 million, under IFRS and delivered to the note holders by January 31, 2006. The supplement agreement changed the date of delivery of the audited financial statements to April 30, 2006.


	•	On June 9, 2006, the Company and the note holders executed a supplemental agreement removing the provision that would have given the note holders an adjustment on the conversion price in the event the Company’s profit after tax for the 12-month period ended February 28, 2006 was less than the amount discussed above.

Details of the carrying value of the convertible notes as of December 31, 2005 and June 30, 2006 are as follows:


	Year Ended			Period ended
	December 31, 2005			June 30, 2006

	$			$
Proceeds from issuance of convertible notes		8,100,000			11,750,000

Fair value of early redemption option		25,000			1,000

Fair value of derivatives related to convertible notes		3,679,000			1,000

Discounts against the debt portion of convertible notes were amortized over the maturity period using the straight-line method which approximates the effective interest rate method. The change in fair value of the derivative liabilities of $316,000 and loss on financial instrument of $263,089 was charged to profit and loss for the year ended December 31, 2005. The change in fair value of the derivative liabilities of $6,997,000 and loss on financial instrument of $1,189,500 was charged to profit and loss for the six-month period ended June 30, 2006.

The fair value of the convertible notes was $71,472,000 at June 30, 2006, which included the fair value of the embedded conversion option.

9.	COMMON SHARES

On October 22, 2001, the Company originally issued 1,000,000 common shares to sole stockholder, Dr. Xiaohua Qu.

10. RESTRICTED NET ASSETS

As stipulated by the relevant laws and regulations applicable to China’s foreign investment enterprise, the Company’s PRC subsidiaries are required to make appropriations from net income as determined under accounting principles generally accepted in the PRC (“PRC GAAP”) to non distributable reserves which include a general reserve, an enterprise expansion reserve and a staff welfare and bonus reserve. Wholly-owned PRC subsidiaries are not required to make appropriations to the enterprise expansion reserve but appropriations to the general reserve are required to be made at not less than 10% of the profit after tax as determined under PRC GAAP. The staff welfare and bonus reserve is determined by the board of directors.

The general reserve is used to offset future extraordinary losses. The subsidiaries may, upon a resolution passed by the stockholder, convert the general reserve into capital. The staff welfare and bonus reserve is used for the collective welfare of the employee of the subsidiaries. The enterprise expansion reserve is for the expansion of the subsidiaries’ operations and can be converted to capital subject to approval by the relevant authorities. These reserves represent appropriations of the retained earnings determined in accordance with Chinese law.

In addition to the general reserve, the Company’s PRC subsidiaries are required to obtain approval from the local PRC government prior to distributing any registered share capital. Accordingly, both the appropriations to general reserve and the registered share capital of the Company’s PRC subsidiaries are considered as restricted net assets of $770,116, $851,516, $4,598,861 and $7,824,160 at December 31, 2003, 2004, 2005 and June 30, 2006, respectively.

The Company was incorporated in Ontario, Canada and is subject to both federal and Ontario provincial corporate income tax.

The major operating subsidiaries, CSI Changshu and CSI Manufacture, are governed by the Income Tax Law of PRC Concerning Foreign Investment and Foreign Enterprises and various local income tax regulations (the “Income Tax Laws”). Pursuant to the PRC income tax law, foreign-invested manufacturing enterprises are subject to income tax at statutory rate of 33% (30% of state income tax plus 3% local income tax) on PRC taxable income.

F-17

CSI Changshu is entitled to a preferential tax rate of 27% (24% of state income tax plus 3% local income tax) as it is located in Changshu Coastal Economic Open-up Area. CSI Manufacture is entitled to a preferential tax rate of 15% as it is located in Suzhou New & Hi-tech District Export Processing Zone.

Foreign-invested manufacturing enterprises are entitled to tax exemption from the state income tax for its first two profitable years of operation, after taking into account any tax losses brought forward from prior years, and a 50% tax deduction for the succeeding three years thereafter. Local income tax is fully exempted during the whole tax holiday. As a result, CSI Changshu was exempted from income tax for the two years ended December 31, 2003 and its applicable income tax rate is 12% for the three years ending December 31, 2006 and CSI Manufacture was exempted from income tax for the two years ended December 31, 2006 and its applicable income tax rate is 7.5% for the three years ending December 31, 2009.
