D. Risk Factors

Risks Related to Our Business

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

We have a limited operating history. We commenced operations in 1999 and shipped our first mixed-signal product in September 2001. Our limited operating history may not provide a meaningful basis for you to evaluate our business, financial performance and prospects, and we may not be able to:

• preserve our leading position in the PC camera multimedia processor market;

• retain and acquire customers;

• diversify our revenue sources by successfully developing and selling multimedia mobile phone processors;

• keep up with evolving industry standards and market developments;

• respond to competitive market conditions;

• maintain adequate control of our expenses;

7

• manage our relationships with our suppliers;

• attract, train, motivate and retain qualified personnel; or

• protect our proprietary technologies.

If we are unsuccessful in addressing any of these risks, our business may be materially and adversely affected.

We may not sustain our recent rates of growth and may incur net losses in the future.

We have experienced significant growth in net revenue and gross profit since 2002. Our net revenue increased substantially from US$50.3 million in 2004 to US$95.3 million in 2005 and US$126.6 million in 2006. Our gross profit increased from US$17.9 million in 2004 to US$36.3 million in 2005 and US$40.4 million in 2006. Our growth reflected a substantial increase in our shipments of PC camera multimedia products, and to a lesser extent, our shipments of mobile phone multimedia products in 2005 and 2006. We do not expect to achieve similar rates of growth in net revenue in future periods as we move from the start-up phase of our business. In addition, we do not expect to sustain our recent rates of growth in gross profit as we enter into the competitive mobile phone multimedia processor market.

Although we generated net income of US$16.4 million in 2005 and US$9.7 million in 2006, we had incurred a net loss of US$5.6 million in 2004. We may incur net losses in the future. We expect to increase our operating expenses in anticipation of expected growth. As a result, any decrease or delay in generating additional sales volume and revenue could materially and adversely affect our results of operations and could result in substantial losses. Our net loss in 2004 included non-cash share-based employee compensation expenses of US$13.4 million. We expect to continue to grant options to employees and consultants in the future and will therefore continue to incur share-based compensation expenses as a result of share-based awards.

We are substantially dependent on sales of our PC camera multimedia processors. A reduction in the volume of PC camera multimedia processors that we sell or the average prices of which we sell them would cause our overall revenue to decline and could materially harm our business.

We have derived a substantial portion of our revenue to date from sales of our PC camera multimedia processors and the third-party sensors we bundled with them. In 2004, 2005 and 2006, we generated approximately 92.9%, 75.3% and 69.5%, respectively, of our net revenue from sales of PC camera multimedia processors and the third-party sensors we bundled with them. Although we began volume shipments of our mobile phone multimedia processors in 2003 and shipments of our mobile phone multimedia processors have substantially increased in 2005 and 2006, we expect that sales of our PC camera multimedia processors will continue to comprise a significant portion of our revenue in the future. Accordingly, any decrease in the demand for our PC camera multimedia processors resulting from the success of competing products, slower than expected growth of the PC camera market or other adverse developments relating to PC cameras may materially and adversely affect our business. In addition, sales of our mobile phone multimedia processors may not increase to a level that would enable us to materially reduce the dependence of our overall financial results on sales of our PC camera multimedia processors.

8

We may not succeed in developing and selling our mobile phone multimedia processors.

We plan to invest significant resources in the development and sale of mobile phone multimedia processors and our ability to achieve significant growth in revenue and gross profit in the near future will depend on our successful development and sales of these products. We only began volume shipments of our mobile phone multimedia processors in 2003, and we do not have significant operating experience in this market. We face significant challenges in the mobile phone multimedia processor business that differs from those we have faced in the PC camera multimedia processor business, including the following:

• technologies, designs and consumer preferences for mobile phones change more rapidly, and product life cycles are shorter, than those for PC cameras;

• mobile phone multimedia processors have more complex product specifications than PC camera multimedia processors;

• mobile phone multimedia processors have more stringent integration, size and power consumption requirements than PC camera multimedia processors;

• the customer base for mobile phone multimedia processors is more fragmented than that for PC camera multimedia processors;

• the mobile phone multimedia processor market is characterized by longer design and sales cycles than the PC camera multimedia processor market; and

• the potential manufacturing volume requirements for mobile phone multimedia processors will be larger than those for PC camera multimedia processors.

We may not be able to successfully address these new challenges in the mobile phone multimedia processor business. Any failure by us to successfully develop and sell mobile phone multimedia processors would have a material adverse effect on our business and prospects.

The growth and success of our business depends on the extent to which mobile phone designers choose to incorporate multimedia processors into mobile phone designs.

Our future growth and success depend on the successful development of the mobile phone multimedia processor market and the acceptance of our products by customers. We cannot predict the growth rate, if any, of the mobile phone multimedia processor market. The development of this market depends substantially on the extent to which mobile phone designers choose to incorporate multimedia processors into mobile phone designs, as opposed to other solutions such as baseband processors that integrate multimedia functions. The failure of the market for mobile phone multimedia processors to expand could have a material adverse effect on the growth and success of our business.

9

The growth and success of our business depends on our ability to respond in a timely manner to the evolving multimedia mobile phone market and changing consumer preferences and industry standards.

Our future growth and success depend significantly on the development of the multimedia mobile phone market, which is evolving rapidly. The development of the multimedia mobile phone market depends on several factors, including changes in end user preferences, demand for multimedia functions and applications on mobile phones, the development of wireless networks to carry increased data traffic, the availability of multimedia-capable mobile phones and the continued provision of subsidies by mobile phone services operators to promote mobile phone upgrades and purchases. In addition, the multimedia mobile phone market is characterized by evolving industry standards, which are difficult for us to predict. If we do not respond to the evolving market, changing consumer preferences and industry standards in a timely manner, the growth and success of our business could be materially and adversely affected.

We have depended on sales of third-party image sensors for a substantial portion of our revenue.

To meet the demand of China-based PC camera manufacturers for more comprehensive system solutions enabling greater ease-of-use and shortened time-to-market for their products, we frequently order image sensors based on our specifications from third-party sensor manufacturers and sell them together with our mixed-signal PC camera multimedia processors. In 2004, 2005 and 2006, we bundled 42%, 61% and 57%, respectively, of our PC camera multimedia processors with third-party sensors. In the same periods, we generated 37%, 37% and 32%, respectively, of our net revenue from the sales of these third-party sensors. At present, there is a limited supply of image sensors for PC camera applications as most of the sensor manufacturers focus on the larger market for mobile phone image sensors. If we are unable to secure an adequate supplies of image sensors, our revenue growth may be adversely affected. In addition, to the extent suppliers of sensors develop PC camera multimedia processors on their own and bundle their processors with sensors, we will face competition from these suppliers and our sales of PC camera multimedia processors could be materially and adversely affected.

Our lengthy time to market makes it difficult for us to forecast revenue and increases the variability of our quarterly results.

Our multimedia processor products are characterized by lengthy intervals between product development and initial volume sales. This interval, commonly referred to as time to market, typically ranges from three to six months for our PC camera multimedia processors and six to nine months for our mobile phone multimedia processors, and may be significantly longer for first-time customers. A number of factors contribute to the length of our time to market. After initially developing a product, we must convince a customer to incorporate it into the design of the customer’s end product, which is referred to as a “design win.” Following the design win, we must complete our product development and deliver our product to the customer, and the customers will then test and evaluate our product before completing the design of its own end product. Our customers may need one to two months or longer to test and evaluate our products and an additional three months or more to commence volume production of end products. Our lengthy time to market makes it difficult for us to forecast revenue and increases the variability of our quarterly results. It also results in a lengthy interval from the time we incur research and development and other operating expenses in connection with a new product to the time that we can first generate revenue from that product. In addition, a design win may never result in volume production or sales of our product. It is possible that we may not generate sufficient, if any, revenue from a new product to offset the increased operating expenses for the development and sale of that product.

10

We may be unable to accurately predict demand for our products, which may result in product shortages or excess inventory or obsolete inventory.

The lead time required by the foundries that we use to fabricate wafers and manufacture our multimedia processors is often longer than the lead time our customers provide to us for delivery of our products to them. These foundries require us to provide forecasts of our anticipated manufacturing needs and place binding manufacturing orders before we receive purchase orders from our customers. This may result in product shortages or excess product inventory because we cannot easily adjust our forecasts and commitments. Obtaining additional supply in the face of product shortages may be costly or impossible, particularly in a short time frame, which could prevent us from fulfilling orders. In line with industry-wide increases in foundry lead times, the lead times the foundries require to manufacture our new multimedia processors have recently grown longer, which has led to an increase in our inventory levels. These lead times may increase further, which may in turn cause us to increase our inventory levels. In addition, like most semiconductor products, our multimedia processors are often susceptible to rapidly declining average selling prices and rapid obsolescence. Excess inventory levels, whether due to our incorrect forecasts, lengthening foundry lead times or other reasons, could result in higher levels of obsolete inventory, unprofitable sales or write-offs of excess or obsolete inventory. Consequently, if we fail to accurately forecast demand for our products, or if longer foundry lead times result in excess inventory levels that result in unprofitable sales or write-offs of inventory, our operating results could fluctuate and the price of our ADSs could decline.

Failure to obtain design wins could have a material adverse effect on our business.

Our success depends on our ability to obtain design wins where PC camera or mobile phone designers decide to incorporate our multimedia processors into their new product designs. Once a multimedia processor designed by a supplier has been incorporated into a PC camera or mobile phone design, the PC camera or mobile phone designer tends to keep the same supplier for the life of the product due to the significant costs associated with qualifying a new supplier. This reluctance to change incumbent suppliers may be an entry barrier for new suppliers such as us. On the other hand, PC camera and mobile phone designers constantly develop and introduce new products to the market, which requires suppliers such as us to continue creating innovative, highly integrated, low-power and cost-effective products and solutions in order to continue achieving design wins from our existing customers. Our failure to achieve design wins could have a material adverse effect on our business.

Our success depends on our customers’ ability to successfully sell their products incorporating our multimedia processors.

Even if a PC camera or mobile phone designer decides to incorporate our multimedia processors into its product or design, the designer may not be able to market and sell its product or design successfully. Even though the designer does not have the right to return the multimedia processors purchased from us, the designer’s inability to market and sell its products, whether from lack of market acceptance or otherwise, could adversely affect our business since, for example, the designer may not order new products from us or we may suffer harm to our reputation. Accordingly, our success depends on our customers’ ability to successfully sell their

11

products incorporating our multimedia processors. We expect that most of our mobile phone multimedia processors will initially be incorporated into mobile phones designed and produced by companies based in China. We are not certain whether these China-based mobile phone designers and manufacturers will be able to sell their products successfully and, if they are successful initially, how long their products will remain competitive in the market.

We depend on third-party foundries to manufacture our multimedia processors. Failure to obtain sufficient foundry capacity could significantly delay our ability to ship our products, cause us to lose revenue and damage our customer relationships.

We do not manufacture our own products. Taiwan Semiconductor Manufacturing Company, or TSMC, in Taiwan, historically manufactured substantially all of our multimedia processors. To diversify our wafer suppliers and reduce our significant dependence on a single foundry, we began to use Fujitsu Microelectronics Asia Pte Ltd, or Fujitsu, and Semiconductor Manufacturing International Corporation, or SMIC, to manufacture some of our products in 2004. In 2004, 2005 and 2006, third party foundries other than TSMC manufactured 25%, 41% and 43%, respectively, of our multimedia processors. Due to our dependence on third-party foundries, we face several significant risks, including:

• failure to secure sufficient manufacturing capacity, or failure to secure sufficient manufacturing capacity at a reasonable cost;

• limited control over delivery schedules, quality assurance and control, manufacturing yields and production costs; and

• the unavailability of, or potential delays in obtaining access to, key process technologies.

The ability of a foundry to manufacture our multimedia processors is limited by its available production capacity. None of these third-party foundries has allocated a fixed level of production capacity to us. It is difficult for us to accurately forecast our capacity needs. We do not have any long-term agreement with any foundry and we typically place orders with them on a purchase order basis, depending on our own customers’ purchase orders and sales forecasts. These foundries can allocate their production capacities to their other customers and reduce deliveries to us on short notice. It is possible that other customers of these foundries are larger and better financed than we are, or have long-term agreements with these foundries, and they may allocate their production capacities to these customers during times of production capacity shortages. Any shortfall in available foundry capacity could significantly delay our ability to ship our products, cause us to lose revenue and damage our customer relationships.

Each of our products is manufactured at only one foundry and if any of these foundries is unable to provide the capacity we need, we may experience delays in shipping our products, which could damage our customer relationships and result in reduced revenue and increased expenses.

Each of our products is manufactured at only one foundry. If any of these foundries is unable to provide us with capacity we need, we could experience significant delays in delivering the product manufactured by that foundry to our own customers. In addition, if any of these foundries experience financial difficulties, suffer damage to its facilities, or experience other disruption to

12

their operations, we may not be able to qualify an alternative foundry in a timely manner, as the qualification process may result in a delay of several months before we can begin to ship our products. Such a delay could damage our customer relationships and have a material adverse effect on our business, financial condition and results of operations.

The principal foundry and one of the assembly and testing houses that we use are both located in a region that is subject to earthquakes, typhoons and other natural disasters, as well as geopolitical risks and social upheaval.

TSMC, the principal foundry upon which we currently rely to manufacture a majority of our multimedia processors, and Advanced Semiconductor Engineering, Inc., or ASE, one of the assembly and testing houses that we use, are both located in Taiwan. Taiwan is susceptible to earthquakes, typhoons, flood and other natural disasters, and has experienced severe earthquakes in recent years that caused significant property damage and loss of life. In addition, TSMC and ASE are subject to risks associated with uncertain political, economic and other conditions in Taiwan and elsewhere in Asia, such as political turmoil in the region and the outbreak of Severe Acute Respiratory Syndrome, or SARS, or another epidemic. The occurrence of any of the foregoing could disrupt their operations, resulting in significant delays in deliveries or substantial shortages of our products and harm to our business.

If the foundries that we use do not achieve expected manufacturing yields, our product costs could increase and product availability could decrease.

The manufacture of semiconductors is a highly complex process. Minute impurities in a silicon wafer can cause a substantial number of wafers to be rejected or cause numerous die on a wafer to be nonfunctional. Foundries encounter difficulties from time to time in achieving acceptable manufacturing yields, which are measured by the percentage of dies produced on a fab line that pass all visual and process control monitoring tests. This often occurs during the production of new products or the installation and start-up of new process technologies. The foundries that we use may not be able to achieve acceptable manufacturing yields as we migrate our designs to smaller geometries. If these foundries do not achieve expected manufacturing yields, our product costs could increase and product availability could decrease.

The loss of the services of either of the two independent assembly and testing houses could significantly disrupt our shipments, harm our customer relationships and reduce our sales.

We rely on two independent assembly and testing houses, ASE and ASAT Holdings Limited, or ASAT, to assemble and test substantially all of our current multimedia processors either for the foundry or directly for us. As a result, we do not directly control our product delivery schedules, assembly and testing costs or quality assurance and control. If either of these assembly and testing houses experiences capacity constraints or financial difficulties or suffers any damage to its facilities, or if there is any other disruption of assembly and testing capacity, we may not be able to obtain alternative assembly and testing services in a timely manner. We do not have long-term agreements with either of our independent assembly and testing houses. We typically procure services from them on a per-order basis. We currently estimate that it would take us at least three to six months to locate and qualify a new assembly and testing house. Because of the amount of time that it takes us to qualify third-party assembly and testing houses, we could experience significant delays in product shipments if we are required to find alternative assembly and testing houses for our products on short notice. Any problems that we may encounter with the delivery, quality or cost of our products could damage our reputation and result in a loss of customers.

We are dependent on a limited number of customers for a significant portion of our revenue and this dependence is likely to continue.

We have been dependent on a small number of customers for a significant portion of our revenue. Our top ten customers collectively accounted for approximately 89%, 76% and 76% of our revenue in 2004, 2005 and 2006, respectively. Sales to our largest customers have varied significantly from period to period. Shenzhen Akkord Electronics Co., Ltd., or Akkord, a China-based original design manufacturer, or ODM, accounted for over 10% of our net revenue in 2004, 2005; Shenzhen Hongtaili Technology Co., Ltd., or Hongtaili, one of our major China-based distributors, accounted for over 10% of our net revenue in 2004, 2005 and 2006; Nanxiang International Limited, or Nanxiang, also one of our major China-based distributors, accounted for over 10% of our net revenue in 2006. We expect that a significant portion of our sales will continue to be generated by a small number of China-based customers. Our largest customers may change from year to year as we continue to expand into the mobile phone multimedia processor market. Our ability to maintain close relationships with these customers is essential to the growth and profitability of our business. If we fail to sell our products to one or more of our major customers in any particular period, or if a large customer purchases fewer of our products, defers orders or fails to place additional orders with us, or if we fail to develop additional major customers, our revenue could decline, and our operating results could be adversely affected.

We rely on third-party distributors for a significant portion of our revenue.

A significant portion of our revenue is derived from sales to distributors who resell our products to manufacturers of modules or end products, such as PC cameras and mobile phones, into which our products are incorporated. Sales to distributors accounted for 41%, 47% and 70% of our net revenue in 2004, 2005 and 2006, respectively. As of December 31, 2006, there were five distributors among our top ten customers. As a result, our ability to maintain good relationships with these distributors is important to the growth of our business and our results from operations. If our major distributors defer orders or fail to place additional orders with us, our revenue could decline and our operating results could be materially adversely affected.

We do not have long-term purchase commitments from our customers, which may result in significant uncertainty and volatility with respect to our revenue from period to period.

We do not have long-term purchase commitments from our customers and our sales are made on the basis of individual purchase orders. Our customers may cancel or defer purchase orders. Our customers’ purchase orders may vary significantly from period to period, and it is difficult to forecast future order quantities. We cannot assure you that any of our customers will continue to place purchase orders with us in the future at the same level as in prior periods. We also cannot assure you that the volume of our customers’ purchase orders will be consistent with our expectations when we plan our expenditures. As a result, our results of operations may vary from period to period and may fluctuate significantly in the future.

14

Defects in our products could result in a loss of customers and decrease in revenue, unexpected expenses and a reduction in market share.

Our products are complex and must meet stringent quality requirements. Complex products such as our highly integrated single-chip products may contain defects, errors and bugs when they are first introduced or as new versions are released. If any of our products has reliability, quality, or compatibility problems, we may not be able to correct these problems on a timely basis. Consequently, our reputation may be damaged and we may fail to obtain design wins, which could harm our ability to retain existing customers and attract new customers. In addition, these defects, errors or bugs could interrupt or delay sales to our customers. Because we cannot test for all possible scenarios, our products may contain errors which are not discovered until after they are shipped. If any of these problems are not found until after we have delivered our products to our customers, we may be required to incur additional development costs and costs associated with product recalls, repairs or replacements. Product defects may also result in product liability claims against us.

Our operating results have fluctuated in the past and we expect our operating results to continue to fluctuate.

Our revenue and operating results are difficult to predict, and have in the past and may in the future fluctuate from period to period. We expect that our revenue will continue to vary from period to period, making it difficult to predict our future operating results. In particular, we experience seasonality and variability in demand for our products as our customers manage their inventories. Our customers tend to increase their inventories of our products in anticipation of the peak fourth quarter buying season for PCs and mobile devices into which our products are incorporated, which often leads to sequentially lower sales of our products in the first and fourth quarters. In addition, business activities in China generally slow down during the Chinese New Year period in the first quarter of each year, which may adversely affect our sales and results of operations during the period. We based our planned operating expenses in part on our expectations of future revenue. If our revenue for a particular quarter is lower than we expect, we may be unable to proportionately reduce our operating expenses for that quarter, which could harm our operating results for that quarter.

Additional factors that could cause our quarterly results of operations to fluctuate include:

• the timing and volume of purchase orders and cancellations from our customers;

• changes in manufacturing costs, including wafer, testing and assembly costs, and manufacturing yields, product quality and reliability;

• the timing and availability of adequate manufacturing capacity of the foundries we use;

• our ability to successfully design and introduce new products in a timely manner that meet our customers’ needs;

• the timing, performance and pricing of new products introduced by us and our competitors;

• the timing and amount of operating expenses incurred by us, including cash bonuses to senior management;

• the liquidity and cash flow of our company and our customers; and

15

• changes in exchange rates, interest rates, tax rates and tax withholding.

Any fluctuations in our quarterly results of operations may affect the price of our ADSs. In future periods, the market price of our ADSs could decline if our revenue and results of operations are below the expectations of analysts and investors.

We may not be able to prevent others from unauthorized use of our intellectual property, which could harm our business and competitive position.

We rely on a combination of patent, copyright, trademark and trade secret laws, as well as nondisclosure agreements and other methods to protect our intellectual property rights. As of December 31, 2006, we owned 196 patents in China and had 566 pending patent applications in China, 30 pending patent applications in the United States, three pending patent applications in Taiwan, three pending patent applications in Japan and three pending patent applications in Korea. We cannot assure you that any patent will be issued as a result of our applications or, if issued, that it will sufficiently protect our intellectual property rights. Implementation of PRC intellectual property-related laws has historically been lacking, primarily because of ambiguities in the PRC laws and difficulties in enforcement. Accordingly, intellectual property rights and confidentiality protections in China may not be as effective as in the United States or other countries. Policing unauthorized use of proprietary technology is difficult and expensive. The steps we have taken may be inadequate to prevent the misappropriation of our proprietary technology. Reverse engineering, unauthorized copying or other misappropriation of our proprietary technologies could enable third parties to benefit from our technologies without paying us for doing so, which could harm our business and competitive position. Though we are not currently involved in any litigation with respect to intellectual property, we may need to enforce our intellectual property rights through litigation. Litigation relating to our intellectual property might result in substantial costs and diversion of resources and management attention. See “—Risks Related to Doing Business in China—Uncertainties with respect to the PRC legal system could have a material adverse effect on us.”

We may face intellectual property infringement claims that could be time-consuming and costly to defend and, if successful, result in our loss of significant rights and inability to continue providing our existing products.

Our success also depends in large part on our ability to use and develop our technology and know-how without infringing the intellectual property rights of third parties. Intellectual property litigation is expensive and time-consuming and could divert management’s attention from our business. If there is a successful claim of infringement against us, we may be required to pay substantial damages to the party claiming infringement, develop non-infringing technology or enter into royalty or license agreements that may not be available on acceptable terms, if at all. Our failure to develop non-infringing technologies or license the proprietary rights on a timely basis would harm our business. 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. Also, we may be unaware of filed patent applications that relate to our products. Parties making infringement claims may be able to obtain an injunction, which could prevent us from selling our products or using technology that contains the allegedly infringing intellectual property. Any intellectual property litigation could have a material adverse effect on our business, operating results or financial condition.

Two of our officers may face claims by their former employer that could consume substantial amounts of management time and attention, as well as result in damage to their and our reputations.

Dr. Zhonghan Deng, our Chairman and Chief Executive Officer, and Dr. Xiaodong Yang, one of our directors and our Chief Technology Officer, were among the co-founders of Vimicro China in 1999. Mr. Deng and Mr. Yang were also co-founders in 1998 of Pixim, Inc., a designer of digital imaging systems for high performance, advanced featured digital camera products based in Silicon Valley, where Mr. Deng was initially Chairman and President and Mr. Yang was initially a director and Vice President in charge of technology development. Mr. Deng left Pixim in May 2001 and became our Chairman, Chief Executive Officer and President at the beginning of 2002. Mr. Yang left Pixim in February 2004 and became our Chief Technology Officer in March 2004. Mr. Yang had also served on our board of directors in 2001 and 2002.

In May 2004, Mr. Deng and Mr. Yang learned that Pixim was contemplating a possible lawsuit against them based upon their alleged failure to disclose their involvement in Vimicro to Pixim and its stockholders and investors, with potential claims in the nature of breach of fiduciary duty, misrepresentation and securities fraud. Mr. Deng and Mr. Yang have informed us that, to date, despite inquiries on their behalf seeking clarification of the potential claims, Pixim has declined to specify the factual or legal basis for any claim and no lawsuit has been filed against Mr. Deng or Mr. Yang. However, we cannot assure you that claims of this nature or other claims will not be brought against Mr. Deng or Mr. Yang by Pixim or its investors, including claims based upon alleged breaches or misconduct by Mr. Deng or Mr. Yang under their contractual obligations to Pixim or alleged infringements of Pixim’s intellectual property rights or misappropriation of its intellectual property assets. Mr. Deng and Mr. Yang have informed us that they believe these potential claims would be without merit if brought. We cannot assure you that similar claims might not also be made against us as a result of Mr. Deng’s and Mr. Yang’s involvement with us as co-founders and contributors of technology and technological expertise to initially capitalize Vimicro and as directors and, later, members of our senior management involved in our technology and product development. If any such claims were made against us, we would intend to contest them vigorously.

Regardless of the outcome, if any such claims were made against Mr. Deng, Mr. Yang or us, litigation could be expensive and could consume substantial amounts of management time and attention, as well as result in damage to their and our reputations, which could have an adverse effect on our operations. An adverse result in litigation could involve damages or equitable relief, and we cannot assure you that such relief would not negatively affect our ability to use our intellectual property, which could have a material adverse effect on our business. The commencement and prosecution of any such litigation, regardless of the outcome, could also have an adverse impact on the price of our ADSs.

Our business depends substantially on the continuing efforts of our senior executives and other key personnel, and our business may be severely disrupted if we lose their services.

Our future success heavily depends upon the continued services of our senior executives and other key employees. We rely on their expertise in multimedia processor design, business operations, sales and marketing and on their relationships with our shareholders, distributors and customers and relevant government authorities. We also rely on a number of experienced mixed-signal semiconductor designers whom are difficult to find since it often requires years of experience to fully master mixed-signal design.

17

We do not maintain key-man life insurance for any of our senior executives and other key employees. If one or more of our senior executives or key employees were unable or unwilling to continue in their present positions, we might not be able to replace them easily or at all. Our business may be severely disrupted, our financial conditions and results of operations may be materially adversely affected, and we may incur additional expenses to recruit, train and retain personnel. Since our industry is characterized by high demand and intense competition for talent, we also may not be able to attract or retain additional highly skilled employees or other key personnel that we will need to achieve our strategic objectives. As we are still a relatively young company and our business has grown rapidly, our ability to train and integrate new employees into our operations may not meet the growing demands of our business.

If any of our senior executives or key employees joins a competitor or forms a competing company, we may lose customers, suppliers, know-how and key professionals and staff members. Each of our executive officers has entered into an employment agreement with us, which contains non-competition provisions. However, if any dispute arises between our executive officers and us, we cannot assure you the extent to which any of these agreements could be enforced in China, where these executive officers reside, in light of the uncertainties with China’s legal system. See “—Risks Related to Doing Business in China—Uncertainties with respect to the PRC legal system could have a material adverse effect on us.”

Our initial option grants to many of our key employees are substantially vested. Therefore, these employees may not have sufficient financial incentives to continue to work for our company, and our ability to successfully operate our business and to execute our business strategy could be impaired if we cannot replace departing key employees in a timely manner.

The share options that we initially granted to many of our key employees have become, or will soon become, substantially vested. While we periodically grant additional share options to key employees after their hire dates, the number of options that we initially grant are usually much larger than in subsequent grants. Employees may be more likely to leave us after the share options that we initially granted to them fully vest, especially if the shares underlying the options have significantly appreciated in value relative to the option exercise price. If any member of our management team or any of our other key personnel leaves our company, our ability to successfully operate our business and execute our business strategy could be impaired. We may also incur significant costs in identifying, hiring, training and retaining replacements for departing employees.

If we fail to manage our growth effectively, our business may be adversely affected.

We have experienced a period of rapid growth and expansion that has placed, and continues to place, significant strain on our management personnel, systems and resources. To accommodate our growth, we anticipate that we will need to implement a variety of new and upgraded operational and financial systems, procedures and controls, including the improvement of our accounting and other internal management systems, all of which require substantial management efforts. We also will need to continue to expand, train, manage and motivate our workforce, manage our customer and distributor relationships and manage our relationship with foundries and assembly and testing houses. All of these endeavors will require substantial management effort and skill and incurrence of additional expenditures. We cannot assure you that we will be able to manage our growth effectively, and any failure to do so may have a material adverse effect on our business.

18

Future acquisitions may have an adverse effect on our ability to manage our business.

If we are presented with appropriate opportunities, we may acquire complementary technologies, businesses or assets. Future acquisitions would expose us to potential risks, including risks associated with the assimilation of new technologies, businesses and personnel, unforeseen or hidden liabilities, the diversion of management attention and resources from our existing business, and the inability to generate sufficient revenue to offset the costs and expenses of acquisitions. Any difficulties encountered in the acquisition and integration process may have an adverse effect on our ability to manage our business.

If we fail to achieve and maintain effective internal control over financial reporting in accordance with the Sarbanes-Oxley Act, we could suffer a loss of investor confidence in the reliability of our financial statements.

We are subject to reporting obligations under the U.S. securities laws. The Securities and Exchange Commission, or the SEC, as required by Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, adopted rules requiring every public company to include a management report on such company’s internal control over financial reporting in its annual report, which must also contain management’s assessment of the effectiveness of our internal control over financial reporting.

Our management has conducted an evaluation of our internal control over financial reporting, and has identified material weaknesses. A description of the material weaknesses is included in “Item 15. Controls and Procedures — Management’s Annual Report on Internal Control over Financial Reporting.” While we have taken and continue to take actions to remedy the material weaknesses in our internal control over financial reporting, we cannot be certain that any remedial measures we have taken or plan to take will be effective or result in the design, implementation and maintenance of adequate controls over our financial processes and reporting in the future. Moreover, even if our management concludes that our internal control over financial reporting is effective in the future, our independent registered public accounting firm may still conclude that our internal control is not effective due to any inability to fully remedy the material weaknesses already identified or additional material weaknesses that may be identified during the audit process or other reasons.

We cannot assure you that we will remedy the material weaknesses, or that additional significant deficiencies or material weaknesses in our internal control over financial reporting will not be identified in the future. If we fail to achieve and maintain effective internal control over financial reporting in accordance with the Sarbanes-Oxley Act, we could suffer a loss of investor confidence in the reliability of our financial statements, which in turn could negatively impact the trading price of our ADSs, result in lawsuits being filed against us by our shareholders or otherwise harm our reputation. Furthermore, we have incurred and anticipate that we will continue to incur considerable costs and use significant management time and other resources in an effort to comply with Section 404 and other requirements of the Sarbanes-Oxley Act.

19

Contractual arrangements between Vimicro China and Vimicro Hong Kong may be subject to scrutiny by the Hong Kong tax authorities and a finding that Vimicro Hong Kong owes additional taxes could substantially reduce our consolidated net income and the value of your investment.

We use Vimicro Hong Kong, a wholly-owned subsidiary of Vimicro China incorporated in Hong Kong, to facilitate a substantial portion of our sales activities primarily due to Vimicro Hong Kong’s close proximity to foundries and assembly and testing houses located in Taiwan and Hong Kong. Vimicro Hong Kong and Vimicro China have entered into certain contractual arrangements pursuant to which Vimicro Hong Kong makes royalty payments to Vimicro China for certain technologies licensed from Vimicro China. We could face material and adverse tax consequences if the Hong Kong tax authorities determine that the contractual arrangements between Vimicro China and Vimicro Hong Kong were not entered into based on arm’s-length negotiations and adjust Vimicro Hong Kong’s income and expenses for Hong Kong tax purposes in the form of a transfer pricing adjustment. A transfer pricing adjustment could, among other things, result in a reduction, for Hong Kong tax purposes, of expense deductions recorded by Vimicro Hong Kong, which could in turn increase the tax liabilities of Vimicro Hong Kong. In addition, the Hong Kong tax authorities may impose late payment fees and other penalties to Vimicro Hong Kong for under-paid taxes. Our consolidated net income may be materially and adversely affected if Vimicro Hong Kong’s tax liabilities increase or if it is found to be subject to late payment fees or other penalties.

Risks Relating to Our Industry

The markets in which we operate are highly competitive, and we cannot assure you that we will be able to compete successfully against our competitors.

The market for multimedia processors is intensely competitive and is characterized by frequent technological change and evolving industry standards. We expect competition to increase, especially in the mobile phone multimedia processor market. Increased competition may result in price reductions, reduced margins and inability to gain or hold market share.

In the PC camera multimedia processor market, we face competition primarily from ALi Corporation, EMPIA Technology, Sonix Technology and Sunplus Technology. We also face competition from large, diversified semiconductor vendors such as Philips.

In the mobile phone multimedia processor market, we face intense competition from vendors of audio processors such as Oki Electric, Rohm, Sunplus Technology, Winbond Electronics Corp. and Yamaha, and vendors of image, video and graphics processors, such as ATI Technologies, CoreLogic, MtekVision, Nvidia, Sanyo, Seiko Epson and Sunplus Technology. In addition, we may face actual or potential competition from established suppliers of semiconductor solutions to mobile phone manufacturers which may attempt to enter our market through, among other means, bundling or integrating multimedia processing functionality with their existing offerings. These suppliers include Analog Devices, Broadcom, Freescale, Infineon, Intel, Mediatek Corporation, NEC Electronics, Philips, QUALCOMM, STMicroelectronics and Texas Instruments.

Many of our competitors have significantly greater financial, technical, manufacturing, marketing, sales and other resources than we do. We cannot assure you that we will be able to compete effectively and increase or maintain our revenue and market share in the PC camera multimedia processor market, or compete successfully against our current or future competitors in the mobile phone multimedia processor market.

20

We are subject to rapidly declining average selling prices, which may harm our revenue and gross profit.

Semiconductor products and electronics products into which they are incorporated are typically sold in high volumes and are subject to rapid declines in average selling prices. We have reduced the prices of many of our products in the past to meet market demand, and expect that we will continue to face market driven pricing pressures on our products in the future. Our financial results will suffer if we are unable to offset any reductions in our average selling prices by developing new or enhanced products on a timely basis with higher selling prices or gross profit margins, increasing our sales volumes or reducing our costs.

We may be adversely affected by the cyclicality of the semiconductor industry.

Our industry is highly cyclical and is characterized by constant and rapid technological change, product obsolescence and price erosion, evolving standards, short product life cycles and wide fluctuations in product supply and demand. The industry has, from time to time, experienced significant downturns, often connected with, or in anticipation of, maturing product cycles of both semiconductor companies’ and their customers’ products and declines in general economic conditions. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices. Any future downturns may reduce our revenue and result in us having excess inventory. Furthermore, any upturn in the semiconductor industry could result in increased competition for access to limited third-party foundry, assembly and test capacity.

Our business could be materially and adversely affected if we fail to anticipate changes in evolving industry standards and to develop and introduce new and enhanced products.

Our products are generally based on industry standards, which are continually evolving. The emergence of new industry standards could render our products or those of our customers unmarketable or obsolete and may require us to incur substantial unanticipated costs to comply with any such new standards. Moreover, our past sales and profitability have resulted, to a significant extent, from our ability to anticipate changes in technology and industry standards and to develop and introduce new and enhanced products. Our continued ability to adapt to such changes and anticipate future standards will be a significant factor in maintaining or improving our competitive position and our prospects for growth. We cannot assure you that we will be able to anticipate the evolving industry standards or that we will be able to successfully develop and introduce new products to meet the new standards. If we fail to anticipate technological change and introduce new products that achieve market acceptance, our business and results of operations could be materially and adversely affected.

Risks Related To Doing Business in China

Adverse changes in political and economic policies of the PRC government could have a material adverse effect on the overall economic growth of China, which could reduce the demand for our products and have a material adverse effect on our competitive position.

Most of our business operations are conducted in China and we believe that a significant portion of devices that our products are incorporated into are ultimately sold to end users in China. Accordingly, our business, financial condition, results of operations and prospects are affected significantly by economic, political and legal developments in China. The Chinese economy differs from the

21

economies of most developed countries in many respects, including the amount of government involvement, the level of development, the growth rate, the control of foreign exchange and the allocation of resources.

While the Chinese economy has experienced significant growth in the past 20 years, growth has been uneven, both geographically and among various sectors of the economy. The PRC government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures benefit the overall Chinese economy, but may also have a negative effect on us. We cannot predict the future direction of economic reforms or the effects such measures may have on our business, financial position or results of operations. Any adverse change in the economic conditions in China, in policies of the PRC government or in laws and regulations in China, could have a material adverse effect on the overall economic growth of China and investment in the semiconductor industry. Such developments could have a material adverse effect on our businesses, lead to reduction in demand for our products and materially and adversely affect our competitive position.

Because our business depends in part on the continuing expansion of the electronics supply chain in China, any slowdown in this expansion could have a material adverse effect on our business and operating results.

Our continuing growth is based upon, among other factors, the continuing expansion of design, manufacturing and other elements of the electronics supply chain in China. This expansion depends on many factors, including China’s ability to continue to attract foreign investment, maintain low costs of operations and supply a well-educated labor force, as well as compete successfully against other countries which desire to establish themselves as preferred supply centers. Any slowdown in the expected expansion of the electronics supply chain in China could have a material adverse effect on our business and operating results.

Uncertainties with respect to the PRC legal system could adversely affect us.

We conduct our business primarily through Vimicro China, which is subject to PRC laws and regulations applicable to foreign investment in China and, in particular, laws applicable to wholly-foreign owned companies. 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 the legal protections available to us. In addition, any litigation in China may be protracted and result in substantial costs and the diversion of resources and management attention.

Our business benefits from certain tax incentives and government grants. Expiration or elimination of, or other adverse changes to, these tax incentives or reductions of these grants could have a material adverse effect on our results of operations.

The PRC government has provided various tax incentives to domestic companies in the semiconductor industry, including Vimicro China, in order to encourage development of the industry. Vimicro China has benefited from tax incentives provided by the PRC tax authorities in the form of preferential tax treatment, reduced tax rates and tax credit, and has also received government

22

research grants and other incentive measures. However, the PRC tax authorities could reduce or eliminate any or all of these tax incentives at any time in the future. For example, on March 16th, 2007, the National People’s Congress adopted the New Income Tax Law, which will become effective as of January 1, 2008 and will replace the existing separate income tax laws for domestic enterprises and foreign-invested enterprises. However, there will be a five-year transition period for foreign-invested enterprises. Since Vimicro currently enjoys the three-year preferential treatment of 10% income tax rate as a “Advanced Technology Enterprise with Foreign Investment” from 2006 to 2008, Vimicro China will still be subject to the 10% income tax rate in 2008 in accordance with the New Income Tax Law. Under the New Income Tax Law, certain qualified “high and new technology companies” may be entitled to a 15% preferential tax rate. However, as the detailed implementation regulation of the New Income Tax Law has not yet been issued, it is unclear whether Vimicro China can qualify as a “high and new technology company” after the New Income Tax Law becomes effective.

In addition, under the New Income Tax Law, a “resident enterprise,” which includes an enterprise established outside of China with management located in China, will be subject to PRC income tax. If the PRC tax authorities subsequently determine that we should be deemed a resident enterprise, then our global income will be subject to PRC income tax at a tax rate of 25%. The exemption to the 20% withholding tax on dividends distributed by foreign-invested enterprises to their foreign investors under the current tax laws may also no longer be available under the new tax law. Since the New Income Tax Law has only been adopted recently, there is uncertainly as to how it should be interpreted or implemented. Any discontinuation of tax preferential tax treatment, any increase of the enterprise income tax rate applicable to Vimicro China, the imposition of PRC income tax on our global income or the imposition of withholding tax on dividends distributed from Vimicro China to us could have a material adverse effect on our financial condition and results of operations.

Furthermore, before April 1, 2005, we were entitled to an immediate rebate for the portion of the value-added tax, or VAT, exceeding 3% of the selling price charged by Vimicro China to our customers in China. Since April 1, 2005, China revoked such VAT rebate. For the year ended December 31, 2004, approximately $110,000 of tax refund was recorded as “other income” after we obtained the required approval from the relevant tax authorities. Such benefit was no longer available in 2005 and 2006. Although the adverse effect of this policy change on our operating results is insignificant because most of our sales were conducted through Vimicro Hong Kong, any further reduction or elimination of any or all of the tax incentives or grants from the government currently provided to Vimicro China could have a material adverse effect on our results of operations.

Vimicro China is subject to restrictions on paying dividends or making other distributions to us.

We are a holding company and we rely on dividends paid by our subsidiaries, including Vimicro China for our cash needs, including the funds necessary to pay dividends and other cash distributions to our shareholders, service any debt we may incur and pay our operating expenses. Regulations in the PRC currently permit payment of dividends only out of accumulated profits as determined in accordance with accounting standards and regulations in China. Vimicro China is required to set aside at least 10% of its accumulated profits each year, if any, to fund certain reserve funds, until the accumulated reserve fund exceeds 50% of its registered capital. These reserve funds are not distributable as cash dividends. If our subsidiary in China incurs debt on its own behalf in the future, the instruments governing the debt may restrict its ability to pay dividends or make other distributions to us.

23

Fluctuations in exchange rates may have a material adverse effect on your investment.

The value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in China’s political and economic conditions. The conversion of RMB into foreign currencies, including U.S. dollars, has been based on rates set by the People’s Bank of China. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the RMB to the U.S. dollar. Under the new policy, the RMB 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 3% appreciation of the RMB against the U.S. dollar by the end of 2006. On May 19, 2007, the People’s Bank of China announced a policy to expand the maximum daily floating range of RMB trading prices against the U.S. dollar in the inter-bank spot foreign exchange market from 0.3% to 0.5%. While the international reactions to the RMB revaluation and widening of the RMB’s daily trading band have generally been positive, with increased floating range of the RMB’s value against foreign currencies, the RMB may appreciate or depreciate significantly in value against the U.S. dollar or other foreign currencies in the long term, depending on the fluctuation of the basket of currencies against which it is currently valued. In additions, 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 RMB against the U.S. dollar. A portion of our net revenue and most of our operating expenses are denominated in RMB, while most of our revenue, cost of revenue and non-operating expenses are denominated in U.S. dollars and Hong Kong dollars, which are pegged to the U.S. dollar. We use the U.S. dollar as the reporting currency for our financial statements. Fluctuations in exchange rates, primarily those involving the U.S. dollar, may affect our costs and operating margins as well as our net income and comprehensive income reported in U.S. dollars. For example, to the extent that we need to convert U.S. dollars we receive from our initial public offering into RMB for our operations, appreciation of the RMB against the U.S. dollar would have an adverse effect on the RMB amount we receive from the conversion. Conversely, if we decide to convert our RMB into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the RMB 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 revenue effectively.

The PRC government imposes controls on the convertibility of RMB into foreign currencies and, in certain cases, the remittance of currency out of China. We receive a portion of our revenue in RMB, which is currently not a freely convertible currency. Under our current structure, our income will be primarily derived from dividend payments from Vimicro China. Under existing PRC foreign exchange regulations, payments of current account items, including profit distributions, interest payments and expenditures from the transaction, can be made in foreign currencies without prior approval from the PRC State Administration of Foreign Exchange, or SAFE, by complying with certain procedural requirements. However, approval from appropriate governmental authorities is required where RMB is to be converted into foreign currency and remitted out of China to pay capital expenses such as the repayment of bank loans denominated in foreign currencies. The PRC government may also at its discretion restrict access in the future to foreign currencies for current account transactions. If the foreign exchange control system prevents us from obtaining sufficient foreign

24

currency to satisfy our currency demands, we may not be able to pay dividends in foreign currencies to our shareholders, including holders of our ADSs. In addition, we cannot be certain that the PRC regulatory authorities will not impose more stringent restrictions on RMB foreign exchange transactions.

Recent PRC regulations relating to the establishment of offshore special purpose companies by PRC residents may subject our PRC resident shareholders to personal liability and limit our ability to inject capital into our PRC subsidiary, limit our subsidiary’s ability to distribute profits to us, or otherwise adversely affect us.

SAFE issued a public notice known as “Circular 75” in October 2005 requiring PRC residents to register with the local SAFE branch before establishing or controlling any company outside of China for the purpose of capital financing, referred to in Circular 75 as a “special purpose offshore company.” Circular 75 become effective on November 1, 2005. Under Circular 75, if an acquisition of a PRC company by a special purpose offshore company controlled by PRC residents occurred before November 1, 2005, such PRC residents were retroactively required to submit a registration form to the local SAFE branch to register their ownership interests in the special-purpose offshore company before March 31, 2006.

We have notified beneficial owners of our company who are PRC residents to register with the local SAFE branch as required under Circular 75. We understand that members of our senior management who are PRC residents have registered with the local SAFE branch. The failure or inability of other beneficial owners of our company resident in the PRC to comply with the registration procedures set forth therein could subject such beneficial owners to fines and legal sanctions and may also limit our ability to contribute additional capital into our PRC subsidiary, limit our PRC subsidiary’s ability to distribute profits to our company or otherwise adversely affect our business.

We face risks related to health epidemics and other outbreaks.

Our business could be adversely affected by the effect of SARS, avian flu, or another epidemic or outbreak, on the economic and business climate. Any prolonged recurrence of SARS, or outbreak of avian flu, or another epidemic in China may have a material adverse effect on our business operations, financial condition and results of operations. For instance, health or other government regulations may require temporary closure of our offices, which will severely disrupt our business operations.

Risks Related to the Shares and ADSs

The market price for our ADSs may be volatile.

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

• actual or anticipated fluctuations in our quarterly operating results and changes or revisions of our expected results;

• changes in financial estimates by securities research analysts;

• conditions in the PC camera and multimedia mobile phone markets;

25

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

• announcements by us or our competitors of new products, acquisitions, strategic relationships, joint ventures or capital commitments;

• addition or departure of our key personnel;

• fluctuations of exchange rates between the RMB, the U.S. dollar and the Hong Kong dollar;

• litigation related to our intellectual property;

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

• sales or perceived potential sales of additional ordinary shares or ADSs.

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 ADSs.

We may need additional capital, and the sale of additional ADSs or other equity securities could result in additional dilution to our shareholders.

We believe that our current cash, cash flow from operations and the proceeds from our initial public offering will be sufficient to meet our anticipated cash needs for the foreseeable future. We may, however, require additional cash resources due to changed business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If these resources are insufficient to satisfy our cash requirements, we may seek to sell additional equity or debt securities or obtain a credit facility. The sale of additional equity securities could result in additional dilution to our shareholders. The incurrence of indebtedness would result in increased debt service obligations and could result in operating and financing covenants that would restrict our operations. We cannot assure our existing shareholders that financing will be available in amounts or on terms acceptable to us, if at all.

Holders of our ADSs may not have the same voting rights as the holders of our ordinary shares and may not receive voting materials in time to be able to exercise their right to vote.

Except as described in this annual report on Form 20-F and in the deposit agreement, holders of our ADSs will not be able to exercise voting rights attaching to the shares evidenced by our ADSs on an individual basis. Holders of our ADSs will appoint the depositary or its nominee as their representative to exercise the voting rights attaching to the shares represented by the ADSs. You may not receive voting materials in time to instruct the depositary to vote, and it is possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote.

26

Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings and you may not receive cash dividends if it is impractical to make them available to you.

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. Under the deposit agreement, the depositary bank will not make rights available to you unless both the rights and the underlying securities to be distributed to ADS holders are either registered under the Securities Act or exempt from registration under the Securities Act. 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 and we may not be able to establish a necessary 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.

The depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on our ordinary shares or other deposited securities after deducting its fees and expenses. You will receive these distributions in proportion to the number of ordinary shares your ADSs represent. However, the depositary may, at its discretion, decide that it is inequitable or impractical to make a distribution available to any holders of ADSs. For example, the depositary may determine that it is not practicable to distribute certain property through the mail, or that the value of certain distributions may be less than the cost of mailing them. In these cases, the depositary may decide not to distribute such property and you will not receive such distribution.

You may be subject to limitations on transfer of your ADSs.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to time when it deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deem it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

Your ability to protect your rights through the U.S. federal courts may be limited, because we are incorporated under Cayman Islands law, conduct a substantial portion of our operations in China and the majority of our directors and officers reside outside the United States.

We are incorporated in the Cayman Islands, and conduct a substantial portion of our operations in China through Vimicro China. A majority of our directors and officers reside outside the United States and a substantial portion of their assets are located outside of the United States. As a result, it may be difficult or impossible for you to bring an action against us or against these individuals in the Cayman Islands or in China in the event that you believe that your rights have been infringed under the securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of China may render you unable to enforce a judgment against our assets or the assets of our directors and officers. There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the courts of the Cayman Islands will generally recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits.

27

You may face difficulties in protecting your interests as a shareholder, as Cayman Islands law provides significantly less protection to shareholders when compared to the laws of the U.S.

Our corporate affairs are governed by our memorandum and articles of association, as amended and restated from time to time, and by the Companies Law (2004 Revision) and common law of the Cayman Islands. The rights of shareholders to take legal action against our directors and us, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from English common law, which has persuasive, but not binding, authority on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedents in the United States. In particular, the Cayman Islands has a less developed body of securities laws as compared to the United States, and provides significantly less protection to investors. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action before the federal courts of the United States. As a result, our public shareholders may have more difficulty in protecting their interests in actions against the management, directors or our major shareholders than would shareholders of a corporation incorporated in a jurisdiction in the United States, and our ability to protect our interests if we are harmed in a manner that would otherwise enable us to sue in a United States federal court may be limited.

As a result of all of the above, our public shareholders may have more difficulty in protecting their interests through actions against us or our management, directors or major shareholders than would shareholders of a corporation incorporated in a jurisdiction in the United States.

Our corporate actions are substantially controlled by our principal shareholders and affiliated entities.

As of December 31, 2006, our principal shareholders and their affiliated entities beneficially owned approximately 39.2% of our outstanding ordinary shares. These shareholders, if acting together, could exert substantial influence over matters such as electing directors and approving material mergers, acquisitions or other business combination transactions. This concentration of ownership may also 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 ADSs. These actions may be taken even if they are opposed by our other shareholders. In cases where their interests are aligned and they vote together, these shareholders will also have the power to prevent or cause a change in control. In addition, these persons could divert business opportunities from us to themselves or others.

We may be classified as a passive foreign investment company, which could result in adverse United States federal income tax consequences to U.S. Holders.

Based on the price of the ADSs and our ordinary shares and the composition of our income and assets, we believe we were not a “passive foreign investment company,” or PFIC, for United States federal income tax purposes for our taxable year ended December 31, 2006. However, we must make a separate determination each year as to whether we are a PFIC (after the close of each

28

taxable year) and we cannot assure you that we will not be a PFIC for our current taxable year ending December 31, 2007 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 (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 future value of our assets is generally determined by reference to the market price of our ADSs and ordinary shares, which may fluctuate considerably. In addition, the composition of our income and assets will be affected by how, and how quickly, we spend the cash we raise in any offering. If we were treated as a PFIC for any taxable year during which a U.S. Holder held an ADS or an ordinary share, certain adverse United States federal income tax consequences could apply to the U.S. Holder. See “Item 10. Additional Information—Taxation—United States Federal Income Taxation—Passive Foreign Investment Company.”

ITEM 4. INFORMATION ON THE COMPANY

A. History and development of the Company

Our legal and commercial name is Vimicro International Corporation. We commenced operations in 1999 through Vimicro China, a company established in China. In February 2004, we incorporated Vimicro International Corporation in the Cayman Islands as an exempted company with limited liability under the Cayman Islands Company Law (2004 Revision). In May 2004, we effected a corporate reorganization whereby all former owners of Vimicro China transferred their ownership interests in Vimicro China to Vimicro International Corporation, and Vimicro China became a wholly-owned subsidiary of Vimicro International Corporation. Following the share transfer, each former owner of Vimicro China and/or its designated nominee subscribed for the shares of Vimicro International Corporation based on such former owner’s pro rata ownership interest in Vimicro China prior to the reorganization.

Vimicro China primarily conducts our research and development, marketing, finance and administrative activities. It currently has two directly wholly-owned subsidiaries:

• Viewtel Corporation, which was incorporated in California in June 1999 to keep abreast of the latest technology developments in the U.S. and to maintain a small team of engineers to conduct advanced research and development activities; and

• Vimicro Electronics International Limited, which was established in Hong Kong in May 2002 to facilitate our sales activities and utilization of third-party foundries and assembly and testing houses located in Taiwan and Hong Kong.

In November 2006, Vimicro Technology, our wholly-owned subsidiary in China was incorporated as a limited liability company with an approved operating period of twenty years. The main business activity of Vimicro Technology is to facilitate domestic sales and perform research and development work.

In November 2005, we completed the initial public offering of our ADSs, each of which represents four ordinary shares, and listed our ADSs on the Nasdaq Global Market.

Our principal executive offices are located at 15/F Shining Tower, No. 35 Xueyuan Road, Haidian District, Beijing 100083, People’s Republic of China. Our telephone number at this address is (8610) 6894-8888 and our fax number is (8610) 8233-5762.

B. Business Overview

Overview

We are a fabless semiconductor company that designs, develops and markets mixed-signal semiconductor products and solutions that enable multimedia capabilities in a variety of products for the consumer electronics and communications markets. Combining our multimedia systems experience with our skills in high performance, low-power, mixed-signal SoC design, we provide customers with comprehensive, system-level solutions that include highly integrated semiconductors, customizable firmware and software, software development tools, reference designs and applications support. We conduct most of our operations in China. Although there are uncertainties with respect to China’s legal and regulatory environment, including its regulations and policies governing dividend distributions, taxes and foreign currency exchange, we believe that we benefit from our access to the high-quality design talent, competitive cost structure, growing electronics design and manufacturing industry, and increasingly significant domestic consumer electronics markets in China.

We are a leading supplier of PC and embedded notebook camera multimedia processors in terms of the number of peripheral PC and embedded notebook cameras shipped worldwide in 2006. Our multimedia processors are incorporated into the products of the largest PC and embedded notebook camera vendors, such as Logitech, as well as well-known notebook computer vendors, such as Lenovo. We seek to establish a leading position in the mobile phone multimedia processor market by leveraging our core multimedia technology capabilities. Our mobile phone multimedia processors have been used by leading international and China-based mobile phone brand owners, such as Samsung, LG, Bird, Lenovo Mobile, Pantech, UTStarcom, ZTE and Huawei as well as leading mobile phone design houses based in China, including China Techfaith Wireless Communication Technology Limited, or China Techfaith, CEC Wireless R&D Ltd., or CECW, and Yuhua Teltech (Shanghai) Co., Ltd., or Yuhua. We intend to continue to identify and actively pursue additional markets which we believe have the potential for high volume sales of multimedia semiconductor products, such as digital home entertainment systems.

Founded in 1999, we began volume shipments of our mixed-signal PC and embedded notebook camera multimedia processors and mobile phone multimedia processors in September 2001 and January 2003, respectively. We have grown significantly since we introduced our first mixed-signal multimedia products in September 2001. Our net revenue increased from US$50.3 million in 2004 to US$95.3 million in 2005 and US$126.6 million in 2006. Our net income amounted to US$16.4 million in 2005 and US$9.7 million in 2006. We had a net loss of US$5.6 million in 2004 due to the share-based compensation expenses recorded in 2004.

Our Solutions and Competitive Strengths

Our solutions consist of semiconductors, software and system-level reference designs. We have designed our solutions to support a broad range of standards, baseband platforms and components in order to facilitate our customers’ designs, assembly and supply chain management processes. We believe that our solutions, our location in China and our team of experienced managers and engineers provide us with a number of significant competitive strengths, including:

• Expertise in Mixed-Signal, System-on-Chip Design. Integrating analog and digital circuits in a single semiconductor product is inherently difficult due to noise interference and other technical challenges. Our experienced teams of mixed-signal design engineers are skilled in integrating a variety of multi-voltage, analog and digital functional building blocks in our SoC designs. Our analog circuits include analog to digital conversion, or ADC, digital to analog conversion, or DAC, power supply management, power amplification and high speed bus physical interfaces. Our digital circuits include embedded memory, micro-controller, embedded RISC CPU, DSP and dynamic power management. The high level of integration of our single-chip products delivers several benefits to our customers, including low power consumption, small size and cost effectiveness. All of our products are implemented in standard CMOS processes and manufactured using leading-edge process technologies.

• Leading Design Capabilities in Audio, Imaging, Video and Communications Algorithms and Related Technologies. Our teams of designers have experience in multimedia systems and a variety of audio, imaging and video technologies, including leading industry standards and compression technologies such as WMA, AAC Plus, MIDI, MP3, MPEG4, H.264 and JPEG. This enables us to integrate multiple multimedia functions in a single semiconductor product. We have created sophisticated high performance signal processing algorithms for many stages of multimedia processing, including sampling, filtering, coding, decoding, synthesis, compression, storage, playback, transmission and receiving (demodulation). Using these algorithms, our multimedia SoC solutions are able to perform image, video and audio DSP functions such as data recovery, signal quality enhancement, noise reduction, sample rate conversion, auto exposure, white-balance and focus control, and video and audio signal reconstruction.

• Proprietary Technologies Enabling High Performance Signal Processing Capabilities. Our mixed-signal multimedia processors enable high performance real-time processing of large volumes of audio, image and video signal data. Our mixed-signal adaptable processor architecture incorporates circuitry that can be modified by software commands to permit different types of tasks to be performed by the same processor. We believe that this architecture allows our products to achieve processing speed, signal quality and power consumption performance comparable to that obtained from competing fixed function hardware. However, unlike fixed function hardware, which is suitable for single applications such as video processing, our products can support a variety of multimedia applications such as audio, video and imaging using a single processor. This allows us to achieve levels of integration comparable to those offered by general-purpose semiconductor devices such as CPUs and baseband processors. Since our processors are designed solely for multimedia applications, rather than a broad spectrum of computing tasks, our processors avoid the need for the complex control software used by CPUs

31

and baseband processors, and can therefore offer significantly better processing speed, signal quality and power consumption performance.

• Application-Level Software Development Capabilities. We seek to differentiate our products and speed our customers’ time-to-market through developing application-level software capabilities. We work closely with other technology leaders to enable innovative multimedia applications through the integration of value-added software features.

• Extensive Network of Sales, Marketing and Customer Support Resources. We have an extensive network of sales, marketing and customer support resources, including offices in Silicon Valley, Taipei, Beijing, Shanghai and Shenzhen. We have entered into distribution and support agreements with partners who we train to support our products to cover additional areas such as Europe and Japan as well as specific large customers in Korea and elsewhere. We maintain an extensive technical support team in Beijing and in other cities in China to provide high-quality, low-cost support services for our global sales force.

• Proximity to the Growing Electronics Design and Manufacturing Industry and Consumer Electronics Markets in China. We market and sell our products and solutions to an increasing number of companies in the electronics industry that have established design, manufacturing and assembly facilities in China. Our close proximity to these facilitates provides opportunities for efficient cooperation, marketing, manufacturing improvements and after-sales support. In addition, domestic consumer demand for electronic devices has increased significantly as a result of the rapid growth in the Chinese economy, which in turn further boosts demand for semiconductor products. We believe that we are well positioned to take advantage of the growth of the electronics design and manufacturing industry and consumer electronics markets in China.

• Ability to Benefit from World-wide Sourcing of Semiconductor Design Talent. Our management and engineering team leaders have significant international experience that they have leveraged in guiding us to our current position as a leading fabless mixed-signal semiconductor design company. We believe that this has enabled us to attract skilled and experienced engineers in Silicon Valley and elsewhere with expertise in mixed-signal design to support our growth and continued technology innovation. In addition, we believe this position gives us a competitive advantage in recruiting candidates from China’s top universities. China has established a significant educational system for advanced semiconductor design and graduates a large number of advanced degree holders in engineering each year, creating a large pool of motivated and qualified candidates. As a result, we have been consistently able to hire qualified engineering graduates at a competitive cost. Recruiting and retaining research and development talent comprises one of the most significant expenses for fabless semiconductor design companies. Our access to high-quality, low-cost design talent in China provides us with a significant competitive advantage relative to semiconductor designers based in higher-cost areas.

Products

Currently, we primarily design, develop and market mixed-signal multimedia processors for PC and embedded notebook cameras, as well as for mobile phones. We provide our customers with comprehensive, system-level solutions that include highly integrated semiconductors, customizable firmware and software, software development tools, reference designs, and applications support. Our products support a broad range of standards, platforms and components in order to facilitate our customers’ designs and their assembly and supply chain management processes. To diversify our product offerings, we have developed and begun to ship our first home TV camera product. In addition, to meet the demand of China-based PC and embedded notebook camera manufacturers for more comprehensive system solutions to enable greater ease-of-use and shortened time-to-market for their products, we frequently order image sensors based on our specifications from third-party sensor manufacturers and sell them together with our mixed-signal PC and embedded notebook camera multimedia processors.

PC and Embedded Notebook Camera Multimedia Processors

We design different models of PC and embedded notebook camera multimedia processors based on the same core technology platform with modifications in successive models with improved performance and functionality. Our PC and embedded notebook camera multimedia processors are fully compatible with sensors that are based on CMOS or CCD technology, the two primary types of technology for sensors. All of our PC and embedded notebook camera multimedia processors are single-chip processors manufactured under our own brand name using our proprietary intellectual property. While our principal focus is on providing our customers with proprietary, high-performance products, we also develop and sell a range of basic, complementary semiconductor products in order to provide more comprehensive solutions for our customers.

Other Products

In order to meet the demand by many of our China-based PC and embedded notebook camera multimedia processor customers for more comprehensive solutions, we frequently order image sensors based on our specifications from third-party sensor manufacturers and bundle them together with our mixed-signal PC and embedded notebook camera multimedia processors. Historically, we developed and sold proprietary VXP solutions to affiliates of China Telecom and China Netcom to help them promote broadband services to end users. We are also developing and selling mixed-signal power management chips as part of our mobile system solutions. In 2006, we shipped 159.7 million units of our power management chips.

Technology

We have developed a broad portfolio of technologies to support multiple functions that are required for multimedia semiconductor solutions. Our products integrate multiple multimedia applications, numerous industry-standard formats, advanced input/output capabilities, analog functions, on-chip memory, complex algorithms to provide high quality still picture, video and audio and are architected to provide efficient use of silicon. Although many functions in multimedia are standards-based, we provide multimedia signal processing that exceeds quality levels required by several important standards to differentiate our customers’ products in the market. We have established a rigorous design process to support the integration of numerous functional blocks into a low-cost single-chip product on a rapid time-to-market schedule. This process enables us to support advanced standards and quickly improve feature-sets to support our customers’ rapid product release cycles. The following paragraphs outline our portfolio of core technologies and describe our mixed-signal design methodology.

Multimedia SoC Design and Video, Imaging, Audio, Graphic, and Communications Technologies

Our teams of designers have experience in multimedia systems and a variety of audio, imaging and video technologies, including leading industry standards and compression technologies such as MIDI, MP3, MPEG and JPEG. This enables us to integrate multiple multimedia functions in a single semiconductor product. We have created sophisticated high performance signal processing algorithms for many stages of multimedia processing, including sampling, filtering, coding and decoding, synthesis, compression, storage, playback, transmission, and receiving (demodulation).

• Video. We possess a broad portfolio of video technologies to support leading industry standards and compression technologies, such as JPEG, MPEG2, MPEG4, AVS and H.264. In addition, we have developed a variety of technologies to provide high video quality and differentiated features, including interlaced to progressive and progressive to interlaced, audio video synchronization, noise reduction, resolution enhancement, sample rate conversion, scaling, auto focus, face tracking algorithms and signal reconstruction.

• Imaging. We have developed a number of image processing algorithm technologies to provide high-quality imaging capabilities in our products. Such technologies include color interpolation, color space conversion and correction, white balance, noise reduction, auto exposure, focus control, resolution enhancement, signal quality enhancement, contrast enhancement and dead pixel detection and correction technologies.

38

• Audio. We have developed a broad portfolio of audio technologies to support leading industry standards and compression technologies such as MIDI, MP3, WMA, AAC, AMR and our proprietary versatile multimedia data (VMD). We have developed several audio processing algorithms and other capabilities to provide a superior aural experience to end-users and differentiate our customers’ products in the market, including wave engine, wave engine codec, surround sound audio, 3D audio, noise cancellation, echo cancellation and all-digital amplifier technologies.

• Graphics. To support graphics capabilities for gaming and other applications in mobile devices, we have developed a number of graphics signal processing capabilities, including support for low power 2D and 3D graphics such as drawing polygons, mobile flash and java.

Analog and Digital Integration

Integrating analog and digital circuits in a single semiconductor product is inherently difficult due to noise interference and other problems. We are experienced in the design of high performance analog and mixed-signal circuitry using CMOS standard process technology, allowing integration of analog and digital functions in our single-chip solutions to achieve lower power, lower cost and more compact products. Our analog and power management circuits include analog to digital conversion, or ADC, digital to analog conversion, or DAC, power supply management, power amplification and high speed bus physical interfaces.

Embedded DSP and Multimedia Signal Processing Algorithms

To support the development of highly integrated multimedia SoC’s incorporating multiple multimedia capabilities, we have developed adaptable processor architecture. The processor can be modified by software commands to reconfigure in a manner optimal for the processing of different types of tasks such as audio, video, imaging and graphics processing. We believe that this architecture allows our products to achieve processing speed, signal quality and power consumption performance comparable to that obtained from competing fixed function hardware that is suitable for a single application such as video processing. Since our processors are designed solely for multimedia applications, rather than a broad spectrum of computing tasks, our processors avoid the need for the complex and power inefficient control and processing software used by general purpose CPUs and baseband processors, and can therefore offer significantly better processing speed, signal quality and power consumption performance than those general-purpose processors.

Design Methodology

Multimedia SoC design usually requires integration of each of the aforementioned technological capabilities into a single chip on a rapid product design cycle. We use a number of industry leading standard and proprietary CAD and design methodologies to accomplish this. Our design methodologies in algorithms, software and hardware co-design enables integration of multimedia signal processing algorithms with mixed-signal design to ensure that our algorithms are optimized for efficient silicon implementation and high yield manufacturing. To meet stringent time-to-market requirements and rapid product cycles of multimedia semiconductor design, we have developed a methodology based on software simulation, hardware simulation, single and multi-FPGA emulation, software-hardware co- simulation, processor based software-hardware co-emulation, and digital and analog co-simulation. In addition, we have developed proprietary multimedia mixed-signal development platforms for system-level integration at the customer site.

Customers

Many of the leading brand owners in our target markets use original design manufacturers, or ODMs, which are companies that specialize in the design and manufacture of products for brand owners. Accordingly, a significant portion of our revenue is derived from our sales to ODMs, who incorporate our multimedia processors in end products that they supply to brand owners. Our major ODM customers include Akkord and Serome Electronics Inc. We also sell our products to distributors, to original equipment manufacturers, or OEMs, who incorporate our multimedia processors in their end products, and to design houses and module manufacturers. In most cases, we ship products to and receive payments directly from distributors and ODMs rather than brand owners for whom the ODMs design and manufacture products. As a result, we do not always have the ability to confirm directly with brand owners that our multimedia processors are incorporated in their end products.

The following is a list of our representative customers in the PC and embedded notebook camera and mobile phone multimedia processor markets during 2006.

Market	Customers
PC and embedded notebook camera multimedia processors	Akkord HanVision Electronics Co., Ltd. Hongtaili Suzhou Logitech Electronics Co., Ltd. Serome Electronics Inc. WooSung Semiconductor Co., Ltd.
Market	Customers
Mobile phone multimedia processors	Samsung Electronics LG NingBo Bird Co., Ltd. China Techfaith Lenovo Mobile Communication Technology Ltd. Pantech Communication, Inc. UTStarcom Inc. ZTE Corporation Huawei Technologies Co., Ltd. JRD Communication Inc Longcheer Holdings Limited Ginwave Technologies

A small number of customers have historically accounted for a substantial portion of our net revenue. In 2006, our top five and top ten customers collectively accounted for approximately 58% and 76%, respectively, of our net revenue for the year. Hongtaili and Nanxiang, our major China-based distributors, contributed 28% and 11%, respectively, of our net revenue in 2006. As we expand our mobile phone multimedia processor business, our overall customer composition as well as the identity and concentration of our top customers are expected to change from period to period.

Sales and Marketing

Our marketing staff works closely with our research and development staff and our customers to develop demand for our products. In designing products, we aim to anticipate our customers’ needs and to meet their increasingly complex and specific design requirements. We also strive to design products that will achieve broad market acceptance and generate widespread end-user demand, including demand for follow-on and derivative products using our solutions. Our time to market typically ranges from three to six months for our PC and embedded notebook camera multimedia processors and six to nine months for our mobile phone multimedia processors, and may be significantly longer for first-time customers.

We sell our products through both direct sales force and distributors. Our direct sales staff is located in Beijing, Shanghai, Shenzhen and Taipei, covering major regional markets in mainland China, Taiwan and Korea. Our direct sales staff includes trained field application engineers who assist our customers in designing, testing and qualifying their devices that incorporate our products. Our network of authorized distributors and representatives also play important roles in our sales, in particular the Taiwan, South Korea and Japan markets, where many of our principal customers are located. We intend to open new sales offices in South Korea. We intend to expand our sales and marketing network to develop new customers in Asia. Our sales are made primarily pursuant to individual purchase orders rather than long-term commitments. Because industry practice allows customers to reschedule or cancel orders on relatively short notice, we believe that our backlog is not a good indicator of our future sales.

The following table summarizes information regarding the regions where we derived revenues from our direct customers for the periods indicated:

	Years ended December 31,
	(in thousands)
	2004		2005		2006
Revenue distribution:
Mainland China	US$	3,745	US$	5,567	US$	5,528
Hong Kong		46,513		89,710		121,036
Total net revenue	US$	50,258	US$	95,277	US$	126,564

Substantially all of our customers are based in Asia. We anticipate that most of our revenues will continue to be derived from sales to our customers in Asia. However, we believe that a significant number of PC and embedded notebook cameras and mobile phones designed and manufactured by our customers are sold to end users outside of the Asia-Pacific region. We generally collect payments from customers shortly before delivering our products. We also offer credit terms to attract and retain large customers.

We engage in marketing activities such as attending conferences and exhibitions and participating in industry specific organizations to promote our products and brand name. For example, in February 2004, we became the only China-based member of the Mobile Industry Process Interface Alliance, a collaboration of mobile industry leaders with the objective to define and promote

41

open standards for interfaces to mobile application processors. We were a founding member of MMTA, which was established in October 2004 by leading participants in China’s telecommunication industry, such as China Mobile, China Unicom, China Telecom, China Netcom, Huawei and ZTE, to promote domestic and international technical innovation and standards and to promote 3G applications in China. MMTA has established a number of key work groups focusing on developing and promoting industry standards in areas such as streaming technology, mobile TV, digital rights management, or DRM, and mobile surveillance. We believe that these activities have been instrumental in promoting our products and brand name among key industry participants.

Manufacturing

We develop our proprietary designs and provide them to third-party foundries to produce silicon wafers for our multimedia processors. By utilizing third-party foundries to produce silicon wafers for our multimedia processors, we are able to focus more of our resources on product design and eliminate the high cost of building and operating advanced semiconductor fabrication facilities. The bulk of our multimedia processors are manufactured with 0.18 micron and 0.09 micron CMOS process technologies. We are developing new products that will be manufactured using even more advanced 90 nanometer CMOS process technology.

We periodically negotiate with these third-party foundries to establish price, volume, timing and other terms. We work closely with these foundries in order to achieve high manufacturing yields in the fabrication process, which is an important aspect of our cost-containment efforts.

We have developed our own automatic testing process for mixed-signal semiconductors and outsource most of our assembly and testing requirements to ASE and the remainder to ASAT. We have also designed and incorporated on-chip test circuits into some of our multimedia processor products. We use standard, readily available packages for all of our products. We currently meet our entire mixed-signal semiconductor testing requirements through the use of logic testing equipment. For cost reduction purposes, we continue to evaluate the relative costs and benefits of outsourcing the testing of our mixed-signal semiconductors.

Quality Assurance

We focus on product quality through all stages of the design and manufacturing process. Our designs are subject to extensive circuit simulation before being committed to test manufacture. In an effort to reduce production cost, we commit a new product to volume production only after sample wafers are fabricated and sample processors are manufactured, packaged and tested. We qualify each of the foundries and assembly and testing companies we use through a series of industry standard product stress tests, as well as an audit and an analysis of their quality assurance system and, in the case of foundries, their manufacturing capability. We also monitor quality and reliability throughout the production cycle by reviewing electrical parametric data from these foundries and assembly and testing companies. We closely monitor foundry production for consistent quality and reliability. We have been certified with ISO 9001 for quality system.

42

Intellectual Property

We design substantially all of our multimedia processors in-house and rely on a combination of patents, trademarks, employee and third-party nondisclosure agreements and licensing arrangement to protect our intellectual property. As of December 31, 2006, we owned 196 patents in China and had 566 pending patent applications in China, 30 pending patent applications in the United States, three pending patent applications in Taiwan, three pending patent applications in Japan and three pending patent applications in Korea. Our issued patents and pending patent applications relate primarily to technology we developed for our multimedia processors. We cannot assure you that any patent will be issued as a result of our applications or, if issued, that it will sufficiently protect our intellectual property rights.

As of December 31, 2006, we registered 62 trademarks in China, including a trademark that incorporates our English name “Vimicro.” We have registered our domain name www.vimicro.com with ChinaDNS.

Competition

The multimedia processor semiconductor industry is highly competitive and dynamic and is characterized by rapid technological changes, evolving industry standards, price reductions and rapid product obsolescence. Our ability to compete effectively depends on defining, designing and regularly introducing new products that meet or anticipate the design needs of our customers’ next generation products and applications. We face competition from various companies, including certain of our customers.

In the PC and embedded notebook camera multimedia processor market, we face competition primarily from ALi Corporation, EMPIA Technology, Sonix Technology and Sunplus Technology, as well as from large, diversified semiconductor vendors such as Philips.

In the mobile phone multimedia processor market, we compete with vendors of audio processors and vendors of image, video and graphic processors. Vendors of audio processors include NEC Electronics, Oki Electric, Rohm, Sunplus Technology, Winbond Electronics Corp. and Yamaha. Vendors of image, video and graphic processors include ATI Technologies, CoreLogic, MtekVision, Nvidia, Sanyo, Seiko Epson and Sunplus Technology. In addition, we also compete with established suppliers of semiconductor solutions to mobile phone manufacturers, which may be in a position to bundle or integrate multimedia processing functionality with their existing products. These suppliers include Analog Devices, Broadcom, Freescale, Infineon, Intel, Mediatek, NEC Electronics, Philips, QUALCOMM, STMicroelectronics and Texas Instruments.

The most significant factors that affect our competitiveness are:

• the performance and cost effectiveness of our products relative to those of our competitors’ products;

• the level of integration and power efficiency of our products;

• the quality and reliability of our products;

• our ability to deliver products in required volumes, on a timely basis and at a competitive price;

43

• our ability to rapidly introduce new products to market; and

• our customer support capabilities.

We believe we compete favorably on the basis of these factors. However, many of our existing and potential competitors have significantly greater financial, technical, manufacturing, marketing, sales and other resources than we do. We cannot assure you that we will be able to compete successfully against our current or future competitors.

REGULATION

The semiconductor industry in China is subject to substantial regulation. This section summarizes the most significant PRC regulations governing our business in China.

Regulations and Policies that Encourage the Development of Semiconductor Design Companies

On June 24, 2000, the State Council promulgated the Several Policies to Encourage the Development of the Software and Integrated Circuit Industry, or the IC Policies. The IC Policies set forth preferential policies on investment, financing, tax, industrial process, technology, income distribution and export-related matters concerning integrated circuit design enterprises, or ICDEs. On the basis of the IC Polices, on October 10, 2002, the Ministry of Finance and the State Administration of Taxation, or the SAT, jointly issued the Notice on Relevant Taxation Policy Issues Concerning the Further Development of the Software and the Integrated Circuit Industries, or the IC Notice, which further specifies the tax treatment afforded to ICDEs. On October 21, 2005, the National Development and Reform Commission, the Ministry of Information Industry, SAT and the General Administration of Customs jointly promulgated the Measures for the Determination of the Integrated Circuit Enterprises Encouraged by the State (for trial implementation), or the Measures. Under the Measures, an integrated circuit enterprise is defined as an entity with independent legal person status established within China and engaged in the manufacturing, assembly, and testing of integrated circuit chips or manufacturing of six-inch or over six-inch monocrystalline silicon material. The definition excludes integrated circuit design enterprises. To apply for the preferential policies, an integrated circuit enterprise must have complied with relevant tax regulations and must meet certain other qualifications.

We conduct our integrated circuit design in China through Vimicro China, which holds an ICDE approval from the Ministry of Information Industry and is eligible for preferential tax treatment under PRC laws relating to ICDEs as described below.

Accreditation of ICDEs

Only duly accredited ICDEs may qualify for preferential industrial policies. Pursuant to a policy entitled Administration of the Accreditation of Integrated Circuit Design Enterprises and Products Procedures, jointly issued by the MII and the SAT, on March 7, 2002, in order to obtain accreditation, an ICDE must (i) be a legally established enterprise whose principal business is semiconductor design; (ii) possess adequate production and quality assurance capabilities; and (iii) generate at least 30% of its total annual revenue from the design of semiconductor products. The MII has designated the China Semiconductor Industry Association to conduct the accreditation of ICDEs.

44

Encouragement of Foreign Investment in ICDEs

Pursuant to the IC Policies and the Guideline Catalogue of Foreign Investment Industries jointly promulgated by the National Development and Reform Commission and the Ministry of Commerce on November 30, 2004, semiconductor design is among the industries in which foreign investment is encouraged by the Chinese government.

Preferential Taxation Policies

Under the IC Policies and the IC Notice, ICDEs are treated as software enterprises for purposes of tax treatment.

Preferential Value-added Tax Policy. Under the IC Notice, from January 1, 2002 to December 31, 2010, IC sales are subject to a VAT levy of 17%. A China-based company was entitled to an immediate refund for any portion of the VAT exceeding 3% of the selling price charged by the China-based company for its sales to customers in China. The China-based company must use the tax refund for the research and development of semiconductors or to increase production. However, pursuant to the Notice on the Elimination of the Value-Added Tax Rebates Policy on Integrated Circuits, effective April 1, 2005, such refund is no longer available to ICDEs.

Exemption of Customs Duties and Import-related Value-added Tax. Under the IC Policies, an ICDE does not need to pay customs duty or import-related VAT on any imported equipment necessary for its own use or any technology, ancillary parts and spare parts that are included in the contract for the equipment. The exemptions from customs duty and import-related VAT do not apply to equipment, technology and parts that are listed on the Catalogue of Imported Commodities for Foreign Investment Projects Not Subject to Tax Exemptions and the Catalogue of Imported Commodities for Domestic Investment Projects Not Subject to Tax Exemptions.

An ICDE may manufacture its self-designed semiconductors overseas if it is not able to manufacture them in China. Pursuant to a notice jointly issued by the Ministry of Finance and the SAT on August 31, 2004, effective October 1, 2004, the import-linked VAT levied on these semiconductors is set at 17%.

Promulgation of PRC New Income Tax Law. On March 16^th, 2007, the National People’s Congress adopted the Enterprise Income Tax Law (the “New Income Tax Law”), which will become effective as of January 1^st, 2008. The New Income Tax Law will replace the exiting separate income tax laws for domestic enterprises and foreign-invested enterprises and impose a unified income tax rate of 25% on both domestic enterprises and foreign-invested enterprises. In accordance with the New Income Tax Law, the existing preferential tax treatments for foreign-invested enterprises would be grandfathered for a period of five years following the effective date of the New Income Tax Law. Enterprises currently entitled to tax exemption and reduction treatments for a fixed period of time may continue to enjoy such benefits until their expiration. Transitional preferential tax treatment shall apply to newly-established hi-tech enterprises receiving priority support from the State and located in special zones prescribed by law to develop foreign economic cooperation and technological exchanges or in areas where the special policies for above-mentioned special zones are implemented with the approval of the State Council. The preferential income tax policies for other State-designated enterprises the development of which is encouraged will continue to be implemented.

45

Intellectual Property Protection for Semiconductors

China has adopted legislation related to intellectual property rights, including trademarks, patents and copyrights. China is a signatory to the main international conventions on intellectual property rights and became a member of the Agreement on Trade Related Aspects of Intellectual Property Rights upon its accession to the World Trade Organization, or WTO, in December 2001. Set forth below are major PRC laws and international treaties effective in China protecting intellectual property rights in semiconductors:

• the Patent Law of the People’s Republic of China, revised at the seventh meeting of the Standing Committee of the ninth National People’s Congress on August 25, 2000 and the revised Implementing Regulations issued by the State Council on June 15, 2001, effective July 1, 2001;

• the Paris Convention for the Protection of Industrial Property of the World Intellectual Property Organization, of which China became a member state on March 19, 1985;

• the General Principles of the Civil Law of the People’s Republic of China adopted at the fourth session of the Sixth National People’s Congress on April 12, 1986, effective January 1, 1987. In this legislation, intellectual property rights were defined in China’s basic civil law for the first time as the civil rights of citizens and legal persons;

• the Regulations for the Protection of the Layout Design of Integrated Circuits, or the Layout Design Regulations, adopted March 28, 2001 at the thirty-sixth session of the executive meeting of the State Council, effective October 1, 2001; and

• the World Intellectual Property Organization’s Washington Treaty on Intellectual Property in Respect of ICs, of which China was among the first signatory states in 1990.

Protection of Integrated Circuit Layout Design

Under the Layout Design Regulations, an integrated circuit layout design is defined as a three-dimensional configuration of a semiconductor circuit that has two or more components, at least one of which is an active component, and part or all of the interconnected circuitry or the three-dimensional configuration has been prepared for the production of semiconductor circuits.

The following persons and entities can hold proprietary rights in the layout designs that they create: (i) PRC natural persons, legal persons or other organizations; (ii) foreign persons or companies whom are creators of an integrated circuit layout design and whose layout designs are first commercially used in China; and (iii) foreign persons or companies from a country that either has an agreement with China concerning the protection of layout designs or is a signatory to an international treaty concerning the protection of layout designs to which China is also a signatory.

A holder of proprietary rights in a layout design may:

• duplicate the entire protected layout design or any part of the original design; and

46

• use the protected layout design, the integrated circuit containing the layout design, or commodities containing the integrated circuit commercially.

The proprietary rights are valid after the layout design is registered with the State Intellectual Property Office in China.

Proprietary rights in a layout design are granted for ten years, commencing from the earlier of the date of the application for registration of the layout design or the first date of its commercial use anywhere in the world. However, a layout design is not entitled to any protection beyond 15 years from the time of its creation, regardless of when the layout design is registered or put into commercial use. The holder of the proprietary rights may transfer those rights to another party or grant permission for use of the design.

Registration of a Layout Design

The State Intellectual Property Office in China decides on applications for registration of layout designs. An application must be made within two years of the design being put in commercial use anywhere in the world, or the application will be rejected.

Compulsory Licenses for Exploitation of Patents in Respect of Semiconductor Technology

Under the Patent Law and the Implementing Regulations of the Patent Law, a company may request the State Intellectual Property Office to grant a compulsory license to use the patent if: (i) three years have passed from the date of granting an invention patent or a utility model patent; and (ii) the company has been unsuccessful in obtaining a license from the holder of the rights despite good faith attempts to obtain the license. A compulsory license for the use of a semiconductor technology patent is restricted to public and non-commercial uses, or to uses that counter anti-competitive actions, as determined by judicial or administrative procedures.

Under the Layout Design Regulations, the intellectual property administration department of the State Counsel may grant a non-voluntary license to use a layout design in the event of a national emergency or any extraordinary state of affairs, where public interest so requires, or where the holder is engaging in unfair competition, as determined by a court or the supervision and inspection against unfair competition department of the State Council. The scope and duration of the license will be determined in accordance with the reasons justifying the grant. The scope shall be limited to non-commercial use for public purposes, or to remedy the holder’s unfair competitive actions as determined by a court or the supervision and inspection against unfair competition department.

Regulations on Foreign Exchange

Foreign 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.

Under the Exchange Rules, the RMB is convertible for current account items, including the distribution of dividends, interest payments, trade and service-related foreign exchange transactions. Conversion of RMB for capital account items, such as direct investment, loan, security investment and repatriation of investment, however, is still subject to the approval of the SAFE or its local branch.

47

Under the Administration Rules, foreign-invested enterprises may only buy, sell or remit foreign currencies at those banks authorized to conduct foreign exchange business after providing valid commercial documents and, in the case of 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 Development and Reform Commission.

Regulations on Dividend Distribution

The principal regulations governing dividend distributions of wholly foreign-owned companies include:

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

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

Under these regulations, wholly foreign-owned companies in the PRC may pay dividends only out of their accumulated profits as determined in accordance with PRC accounting standards. In addition, these wholly foreign-owned companies are required to set aside at least 10% of their respective accumulated profits each year, if any, to fund certain reserve funds, until the accumulative amount of such fund reaches 50% of its registered capital. At the discretion of these wholly foreign-owned companies, they may allocate a portion of their after-tax profits based on PRC accounting standards to staff welfare and bonus funds. These reserve funds and staff welfare and bonus funds are not distributable as cash dividends.

In addition, under SAFE’s Circular 75, which became effective on November 1, 2005, PRC subsidiaries of offshore parent companies may be prohibited from making distributions of profits to their offshore parent companies or paying the offshore parent companies proceeds from any reduction in capital, share transfer or liquidation, unless PRC shareholders with a direct or indirect stake in such offshore parent companies make the required SAFE registrations.

SAFE Registration Relating to the Establishment of Offshore Special Purpose Companies and Round-trip Investment by PRC Residents

Under Circular 75, if an acquisition of a PRC company by a special purpose offshore company controlled by PRC residents occurred before November 1, 2005, such PRC residents were required retroactively to submit a registration form to the local SAFE branch to register their ownership interests in the special-purpose offshore company before March 31, 2006. Such PRC residents must also amend such registration form if there is a material event affecting the offshore company, such as, among other things, a change to the company’s share capital, a transfer of shares, or if the company is involved in a merger, an acquisition or a spin-off transaction or provides guarantees to other entities.

In accordance with Circular 75, failure to register with the SAFE could subject such PRC residents to personal liability, and may also limit our ability to contribute additional capital into our PRC subsidiary or our subsidiary’s ability to distribute dividends to us, or otherwise adversely affect our business.

C. Organizational Structure

The following table sets out the details of our subsidiaries:

Name	Country of Incorporation	Ownership Interest
Vimicro Corporation	People’s Republic of China	100%
Vimicro Technology Corporation	People’s Republic of China	100%
Viewtel Corporation	California, U.S.A.	100%
Vimicro Electronics International Limited	Hong Kong Special Administrative Region	100%

We conduct substantially all of our business through our wholly-owned subsidiaries. Vimicro China primarily conducts our research and development, marketing, finance and administrative activities. It currently has two directly wholly-owned subsidiaries: Viewtel Corporation, and Vimicro Electronics International Limited. Vimicro Technology was incorporated in Shenzhen, PRC in November 2006 as a limited liability company with an approved operating period of twenty years. The main business activity of Vimicro Technology is to facilitate domestic sales and perform research and development works. There were no activities in Vimicro Technology in 2006.

D. Property, Plant and Equipment

We are a fabless semiconductor company. We develop our proprietary designs and provide them to third-party foundries to produce silicon wafers for our multimedia processors. Therefore, we do not have manufacturing facilities of our own.

Our principal executive offices are located on premises comprising approximately 9,200 square meters in Beijing, China. We have regional offices in Shanghai, Shenzhen and Mountain View, California. We lease substantially all of our premises from unrelated third parties. We believe that we will be able to obtain adequate facilities, principally through leasing of appropriate properties, to accommodate our future expansion plans.

In December 2006, Vimicro China entered into an agreement with Beijing Haidian Xinhua Agricultural Industrial & Commercial Co. to acquire the land-use rights for approximately 29,000 square meters of land (including a construction site area of approximately 7,900 square meters) in Haidian District, Beijing. The land will be the site of a new building, which will become Vimicro China’s new headquarters and accommodate a research and development center. The aggregate consideration for the acquisition of the land-use rights and the construction of the new building is estimated to be approximately US$38.3 million. The proposed project, including the gross land area and construction site area, is subject to governmental approval. Should the governmental authorities request us to modify the project, the land and construction site areas, as well as the total cost for the project, may change. It is estimated that the construction of this new building will be completed by 2009.

On June 27, 2007, we entered into an agreement with Shenzhen Municipal Bureau of Land Resources and Housing Management, pursuant to which, in consideration of approximately US$856,000, we acquired land use rights for approximately

49

3,947 square meters of land in Shenzhen High-Tech Industrial Park. The land will be the site of a new building, which will become Vimicro Technology’s office building and accommodate a research and development center. Governmental authorities would require us to obtain necessary governmental approvals for the proposed project. It is estimated that the construction of this new building will be completed by 2009.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our consolidated financial statements and the related notes included elsewhere in this annual report on Form 20-F. This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Item 3. Key Information—D. Risk Factors” or in other parts of this annual report on Form 20-F.

A. Operating Results

Overview

We are a fabless semiconductor company that designs, develops and markets mixed-signal semiconductor products and solutions that enable multimedia capabilities in a variety of products for the consumer electronics and communications markets. Combining our multimedia systems experience with our skills in high performance, low-power, mixed-signal SoC design, we provide customers with comprehensive, system-level solutions that include highly integrated semiconductors, customizable firmware and software, software development tools, reference designs and applications support. We have grown significantly since we introduced our mixed-signal multimedia products in September 2001. Our net revenue increased from US$50.3 million in 2004 to US$95.3 million in 2005 and US$ 126.6 million in 2006. Our gross profit increased from US$17.9 million in 2004 to US$36.3 million in 2005 and US$ 40.4 million in 2006. We had a net loss of US$5.6 million in 2004 due to US$13.4 million share-based employee compensation expenses recorded in 2004. Our net income amounted to US$ 16.4 million in 2005 and US$ 9.7 million in 2006. Our limited operating history makes the prediction of future operating results very difficult. We believe that period-to-period comparisons of operating results should not be relied upon as predictive of future performance.

We currently derive a significant portion of our revenue from sales of mixed-signal PC and embedded notebook camera multimedia processors. In the future, we intend to derive an increasing percentage of our revenue from mobile phone multimedia processors and other new mixed-signal products that we develop to address the needs of additional markets which we believe have the potential for high volume sales of multimedia products.

In reviewing our performance, we focus on the following non-financial factors: our market penetration, the features and performance of our products, our number of design wins, the length of our product sales cycles, and shipment volumes of our products. We evaluate our performance in respect of these non-financial factors against our operating plans. We also focus on the following key financial factors: revenue, gross profit margins and operating expenses.

50

While our business is influenced by factors affecting the semiconductor industry generally and by conditions in each of the markets we serve, we believe our business will be influenced by company-specific factors such as our ability to continually improve our product development capabilities, increase our sales and improve our operations. We expect that our ability to grow our business will depend on our success in penetrating our target markets.

Our gross profit margins have historically fluctuated and are expected to continue to fluctuate due to several factors, including changes in the relative mix of our products, the per-unit costs for our products, and the average selling prices for our products. We have been able to reduce the average per-unit costs for our products primarily due to our ability to negotiate more favorable pricing terms with the foundries and testing houses we use as we have achieved higher shipment volumes, as well as our ability to improve the manufacturing yields of our products over time through our manufacturers and reduce the size and cost of our products through the migration of our designs to more advanced semiconductor manufacturing processes, for example, from .25 micron CMOS to .09 micron CMOS manufacturing processes. We expect to continue to face price pressure on our products as average selling prices for semiconductor products generally decline over time. However, the average selling price decline may be mitigated by developing and marketing successive generations of products with lower unit costs than prior generations. In order to maintain or improve our gross profit margins, we need to continue to introduce new, lower cost products, increase sales volumes and reduce unit costs.

We expect that the total amount of our operating expenses will generally grow over time. Our research and development expenses are expected to increase as we continue to develop new multimedia products and increase our headcount. Our sales and marketing expenses are expected to grow as we expand our sales and marketing network globally and engage in additional marketing and promotional activities. Our general and administrative expenses are expected to increase, reflecting the hiring of additional personnel and other costs related to the anticipated growth of our business, as well as the higher costs of operating as a publicly-traded company.

We use a limited number of third-party foundries to manufacture our multimedia products, and we rely on a limited number of independent assembly and testing houses to assemble and test substantially all of our multimedia processors. We believe that this business model enables us to reduce our capital expenditures and fixed costs relative to semiconductor companies that manufacture, assemble and test their own products, while focusing our engineering and design resources on our core strengths. We do not have any long-term agreement with any foundry or assembly and testing house and we typically place orders with them on a purchase order basis, depending on our customers’ purchase orders and sales forecasts.

Multimedia processors are characterized by a lengthy time to market, which is the interval between product development and initial volume sales. The time to market typically ranges from three to six months for our PC and embedded notebook camera multimedia processors and six to nine months for our mobile phone multimedia processors, and may be significantly longer for first-time customers. Our lengthy time to market makes it difficult for us to forecast our revenue and increases the variability of our quarterly results. It also results in a lengthy interval from the time we incur research and development and other operating expenses in connection with a new product to the time that we can first generate revenue from that product.

51

We operate and manage our business as a single segment. We do not account for our results of operations on a geographic or other basis, and we do not allocate operating expenses among our products.

Vimicro International Corporation was incorporated in the Cayman Islands in February 2004 as an exempted company with limited liability. In connection with our corporate reorganization in May 2004, all of the former owners of Vimicro China transferred their equity interests in Vimicro China to Vimicro International Corporation, and they and/or their designated nominees subsequently subscribed for shares of Vimicro International Corporation based on their respective proportionate interests in Vimicro China prior to the reorganization. The reorganization has been accounted for as capital stock reorganization, and as a result, Vimicro China is considered to be the predecessor of Vimicro International Corporation. Our consolidated financial statements are presented as if Vimicro International Corporation had been in existence for all of the periods presented.

Revenue

The following table sets forth our net revenue derived from PC and embedded notebook camera multimedia processors, image sensors, mobile phone multimedia processors and other products, respectively, in amounts and as percentages of total net revenue for the periods indicated. Our net revenue reflects a deduction for customer rebates and business taxes and related surcharges incurred in connection with our operations in China.

Total net revenue	50,258	100.0	95,277	100.0	126,564	100.0

Cost of Revenue and Gross Profit

Our cost of revenue primarily consists of costs associated with the fabrication of wafers, the assembly, testing and shipping of our multimedia processors, amortization of costs associated with production masks and tooling, and costs of third-party products that we sell to our customers. As we do not have long-term, fixed supply agreements with third-party foundries and assembly and testing companies, our costs for wafer fabrication, assembly and testing are susceptible to changes based on conditions in the global semiconductor market. We expect that our cost of revenue will increase as our sales volume increases, offset in part by reduced per-unit costs of wafer fabrication, assembly and testing over larger volume shipments.

52

Our gross profit margins increased from 35.5% in 2004 to 38.1% in 2005 primarily because a significant increase in our sales volume enabled us to obtain a substantial reduction in the per-unit costs for wafer fabrication, assembly and testing of PC and embedded notebook camera multimedia processors and mobile phone multimedia processors. These cost reductions were partially offset by a slight decline in the average selling prices of our products and a decrease in our gross profit margins resulting from a change in our products purchased by our customers. Our gross profit margins decreased from 38.1% in 2005 to 31.9% in 2006 primarily due to the decline of the average selling price of our products and the increase in our product mix of the proportion of relatively lower margin products. Our sales of mobile phone multimedia processors, which have lower per-unit margins compared to our PC and embedded notebook camera multimedia processors, increased from 10.7 million units in 2005 to 18.6 million units in 2006. As we continue to increase shipments of mobile phone multimedia processors, we expect that our average gross profit margins on our multimedia processors will decrease because the mobile phone multimedia processor market is characterized by higher unit shipment volumes but lower gross margins as compared with the PC and embedded notebook camera multimedia processor market. Our sales of third-party sensors increased from 13.6 million units in 2005 to 20.2 million units in 2006, and our gross profit margins on those sales increased in 2006 compared to 2005. This improvement was primarily due to the new products with greater margin.

Semiconductor products and electronic devices into which they are incorporated are typically sold in high volumes and are subject to rapid declines in average selling prices. We have reduced the prices of many of our products in the past to meet market demand, and expect that we will continue to face market driven pricing pressures on our products in the future. Therefore, there is no assurance that we will be able to maintain our gross profit margins in the future.

Operating Expenses

Our operating expenses primarily consist of research and development expenses, sales and marketing expenses and general and administrative expenses, each of which includes share-based employee compensation expenses.

Share-based Employee Compensation

Following the incorporation of Vimicro International Corporation, we granted options to purchase a total of 17,574,448 ordinary shares in March 2004 to our current and former employees to honor the commitments previously made by Vimicro China during the period from 1999 to the date of grant. In 2004, we recognized a total of US$13.4 million of share-based employee compensation expense. Due to the difference between the option exercise prices and the estimated fair value of our ordinary shares at the time of grant, in 2005, we recognized a total of US$1.4 million of share-based employee compensation expense as a result of the amortization of a portion of the US$2.1 million of deferred expenses incurred in connection with our March 2004 option grants over the vesting periods of the options granted. In 2006, we recognized a total of US$ 2.7 million of share-based employee compensation expenses.

53

We adopted a 2004 share option plan, or 2004 plan, and granted a total of 2,701,200 options to our employees under the 2004 plan in 2005. For a description of our 2004 plan, see “Item 6. Directors, Senior Management and Employees—B. Compensation of Directors and Executive Officers—Share Options. Our board of directors and shareholders also adopted a 2005 share incentive plan, or 2005 plan. For a description of our 2005 plan, see “Item 6. Directors, Senior Management and Employees—B. Compensation of Directors and Executive Officers—Share Options.” For the years ended December 31, 2005 and December 31, 2006, 313,200 and 12,107,400 options were granted under the 2005 plan.

We have adopted SFAS No. 123R with effect from January 1, 2006, under which share-based compensation expense is determined based on the fair value of share option as of the option grant date. Prior to the adoption of SFAS No. 123R, we accounted for the share-based awards in accordance with APB No. 25 “Accounting for Stocks Issued to Employees”. Our share-based compensation expense increased in 2006 as compared to 2005 from the expensing of the option granted in 2006.

Research and Development

Research and development expenses consist primarily of salaries, bonuses, and benefits for research and development personnel, lease expenses for occupancy associated with research and development, costs of engineering services from contractors and consultants, depreciation of engineering equipment and share-based compensation expenses. Our research and development expenses have been offset by the government and private grants that we received. We received grants from various PRC government authorities from 2004 through 2006, and we also received grants from a leading global software company from 2004 through 2006. The aggregate amounts of the grants we received were US$2.1 million, US$1.4 million and US$ 2.6 million in 2004, 2005 and 2006, respectively. Each grant is associated with a particular research and development project that we have undertaken. When we apply any portion of a grant to the related project for which qualified expenses have been incurred, our research and development expenses for the period are offset by the amount applied. We applied a total of US$2.3 million, US$1.9 million and US$ 3.3 million of these grants to research and development projects in 2004, 2005 and 2006, respectively. As of December 31, 2006, we had total unused grants of US$210,399. There is no assurance that we will continue to receive grants from PRC government authorities or any other party in the future. We expect that our total research and development expenses, including, among others, costs incurred in connection with hiring additional research and development staff and purchase of intellectual property, will increase as we continue to develop new multimedia products.

Sales and Marketing

Sales and marketing expenses consist primarily of salaries, bonuses, benefits, advertising, promotion and related costs for sales and marketing personnel, travel and other expenses related to sales and marketing activities, and sales commissions to our distributors in Asia. We expect that our total sales and marketing expenses will increase as we hire additional sales and marketing personnel, expand our sales and marketing network globally to promote and sell our multimedia processor products, and engage in additional marketing and promotional activities.

54

General and Administrative

General and administrative expenses consist primarily of salaries, bonuses, benefits and related costs for administrative personnel, travel, lease and other expenses for general and administrative purposes, as well as costs for outside services, including legal and accounting services. We expect that our total general and administrative expenses will increase as we hire additional personnel and incur costs related to the anticipated growth of our business and our operation.

Taxation

Cayman Islands

Under the current laws of the Cayman Islands, we are not subject to tax on our income or capital gains. In addition, no Cayman Islands withholding tax will be imposed on payments of dividends by the Company to its shareholders.

PRC

Enterprise Income 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, or FIEs, incorporated in the PRC are generally subject to an enterprise income tax rate of 33%. The Income Tax Law and the related implementing rules also provide certain favorable tax treatments to FIEs which qualify as “high or new technology enterprises” and are registered and operate in specified high-tech zones in the PRC. PRC domestic companies are governed by the Enterprise Income Tax Laws of the PRC and are also generally subject to an enterprise income tax rate of 33%.

Vimicro China, an FIE which is registered and operates in a high-tech zone of Beijing Zhongguancun Science Park, has been qualified as a “high or new technology enterprise.” As a result, it is entitled to a preferential enterprise income tax rate of 15%. It was entitled to a three-year exemption from the enterprise income tax from its first year of operation (which expired on December 31, 2002) and was thereafter entitled to a preferential enterprise income tax rate of 7.5% for the succeeding three years (which expired on December 31, 2005). After December 31, 2005, Vimicro China is subject to a preferential enterprise income tax rate of 15% so long as it continues to operate in the high-tech zone and maintains its “new or high technology enterprise” status.

To qualify as a “high or new technology enterprise” for PRC enterprise income tax purposes, a business entity generally must meet certain financial and non-financial criteria, including, but not limited to:

• a minimum level of revenues generated from high technology related sales or services as a percentage of total revenues;

• a minimum number of employees engaged in research and development; and

• a minimum research and development expenses as a percentage of total revenues.

55

Vimicro China’s status as a “high or new technology enterprise” is re-assessed every other year.

On March 8, 2006, Vimicro China was approved by the Ministry of Commerce of the People’s Republic of China to be qualified as a “Advanced Technology Enterprise with Foreign Investment.” According to the regulations of the Beijing Municipal Office of State Administration of Taxation, an enterprise with this qualification is entitled to a preferential enterprise income tax rate for the three years following the receipt of this qualification, equal to the higher of 10% or half of the applicable tax rate. As a result, on April 4, 2006, Vimicro China received an approval from Beijing Municipal Office of State Administration of Taxation and is entitled to a 10% preferential income tax rate from 2006 to 2008.

On March 16th, 2007, the National People’s Congress adopted the New Income Tax Law, which will become effective as of January 1, 2008 and will replace the existing separate income tax laws for domestic enterprises and foreign-invested enterprises. However, there will be a five-year transition period for foreign-invested enterprises. Since Vimicro currently enjoys the three-year preferential treatment of 10% income tax rate as a “ Advanced Technology Enterprise with Foreign Investment” from 2006 to 2008, Vimicro China will still be subject to the 10% income tax rate in 2008 in accordance with the New Income Tax Law. In addition, under the New Income Tax Law, a “resident enterprise,” which includes an enterprise established outside of China with management located in China, will be subject to PRC income tax. If the PRC tax authorities subsequently determine that we should be deemed a resident enterprise, then our global income will be subject to PRC income tax at a tax rate of 25%. Under the New Income Tax Law, certain qualified “high and new technology companies” may be entitled to a 15% preferential tax rate. However, as the detailed implementation regulation of the New Income Tax Law has not yet been issued, it is unclear whether Vimicro China can qualify as a “high and new technology company” after the New Income Tax Law becomes effective.

The amount of income tax payable by Vimicro China in the future will depend on various factors, including, among other things, its results of operations, taxable income, the amount of its deductible research and development expenses, and the statutory tax rate applicable to it. Our effective tax rate depends partially on the extent of each of our subsidiaries’ relative contribution to our consolidated taxable income.

Value-added Tax. According to PRC value-added tax policy, Vimicro China is subject to an output Value-added Tax, or VAT, at 17% of selling price of products sold to customers in China, while the purchase of products by Vimicro China is subject to an input VAT at the rate of 17%. VAT payable is the net difference between periodic output VAT and deductible input VAT. Prior to April 1, 2005, Vimicro China, subject to approval by relevant tax authority, is entitled to VAT refund for the portion exceeding 3% of the actual VAT collected by Vimicro China for sales of integrated circuits (including mono-crystalline silicon chips) to customers in China. The above VAT refund benefit was no longer available since April 1, 2005.

For the year ended December 31, 2004, approximately $110,000 of tax refund was recorded as “other income” after we obtained the required approval from the relevant tax authorities. Such benefit was no longer available in 2005 and 2006.

56

The adverse effect of the above tax policy change on Vimicro China’s operation have been concluded insignificant due to the fact that most of the sales are through Vimicro Hong Kong which are not subject to PRC VAT.

Business Tax. According to PRC business tax policy, service income generally is subject to business tax at 5%. Vimicro China is entitled to business tax exemption on income arising from or related to technology transfers provided these technology transfer agreements are registered with the relevant government agencies.

United States

Viewtel, the subsidiary incorporated in the United States, is subject to state income tax and federal income tax at different tax brackets, depending upon taxable income levels. Viewtel incurred income tax expenses of approximately $58,000, $8,000 and $132,650 for the years of 2004, 2005 and 2006, respectively.

Hong Kong

Profit Tax. Corporations carrying on any trade or business in Hong Kong are subject to profit tax on assessable profits arising or derived from Hong Kong from such trade or business. The effective profit tax rate is 17.5% for 2004, 2005 and 2006.

Vimicro Hong Kong, the Hong Kong subsidiary of Vimicro China, calculated Hong Kong profit tax for 2004 and 2005 on the basis that it is subject to Hong Kong profit tax for these years. Income tax expenses were approximately $35,000 and $201,000 for 2004 and 2005, respectively. However, Vimicro Hong Kong applied for offshore status with Hong Kong Inland Revenue Department in September, 2006 to claim offshore status for all years since the start of its operation in 2002 and filed amended tax returns. Based on the territorial source principle of taxation in Hong Kong, it is highly likely that Vimicro Hong Kong will be successful in its offshore status application. An adjustment was made in 2006 to reflect the accumulative changes as a result of the change in filing status.

Withholding Tax. Under the current Hong Kong tax laws, an entity established outside of Hong Kong is subject to a 5.25% withholding tax on royalty income received from an entity established in Hong Kong, regardless of whether the two entities are controlled by the same holding company. Vimicro Hong Kong makes royalty payments to Vimicro China for certain technologies licensed from Vimicro China. Before applying for offshore status, Vimicro China was subject to a 5.25% withholding tax on royalties received from Vimicro Hong Kong, which Vimicro Hong Kong withheld and paid over to the tax authorities in Hong Kong on behalf of Vimicro China. Upon approval by the relevant PRC tax authorities, the amount of withholding tax paid on royalty income to Hong Kong tax authority can be treated as a foreign tax credit by Vimicro China. Thus, such payment can be used to offset the tax payable on the same source of income for PRC tax purpose.

In connection with the offshore status claim in 2006, Vimicro China will not be subject to Hong Kong withholding tax on royalty income if Vimicro Hong Kong succeeds in its offshore status claim.

57

Internal Control Over Financial Reporting

Under the supervision of the audit committee, our management has conducted an evaluation of our internal control over financial reporting as of December 31, 2006 based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our internal control over financial reporting includes those processes and procedures that (i) pertain to the maintenance of records that accurately and fairly reflect the transactions and dispositions of assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of assets that could have a material effect on the financial statements.

A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the financial statements will not be prevented or detected. The following material weaknesses have been identified and included in management’s assessment as of December 31, 2006:

The Company did not maintain effective controls over the financial reporting process due to an insufficient complement of personnel with a level of accounting knowledge, experience and training in the application of generally accepted accounting principles commensurate with the Company’s financial reporting. This material weakness contributed to the following control deficiencies, each of which is considered to be a material weakness:

(a). The Company did not maintain effective controls over the completeness and accuracy of the Company’s income tax balance sheet accounts and its related provision for income taxes. Specifically, the Company did not maintain effective controls over the uncertain tax positions and related analysis and accounting treatments. This control deficiency resulted in subsequent revisions and late adjustments to our income tax expense and related income tax balance sheet accounts in the 2006 annual consolidated financial statements.

(b) The Company did not maintain effective controls over its process to ensure the completeness and accuracy of the inventory balance. Specifically, the Company did not have effective controls over the process for estimating our provision for obsolete and excess inventory. This control deficiency resulted in subsequent revisions and late adjustments in our inventory provision at December 31, 2006.

These control deficiencies resulted in revisions in our financial statements and the delay in the finalization of our financial statements for the year ended December 31, 2006. In addition, these control deficiencies could result in a more than a remote likelihood that inaccurate accounts or disclosures, which may constitute a material misstatement of the consolidated financial statements, could occur. Accordingly, our management has determined that these control deficiencies constitute material weaknesses. Due to the existence of such material weaknesses, the Company did not maintain effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control – Integrated Framework issued by the COSO.

58

This annual report does not include a report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to audit by the Company’s registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit the Company to provide only management’s report in this annual report.

Remediation of Material Weaknesses

Our management has determined that these material weaknesses above were mainly caused by higher-than-expected attrition of personnel with U.S. GAAP reporting experience during the financial reporting season. Since such issue was identified, we have implemented, and will continue to implement, remedial measures to address this issue and to improve our internal control over financial reporting. Our audit committee has been actively involved during the preparation of our annual financial report, and, in 2007, we have hired a number of qualified personnel with accounting and financial reporting experience who are familiar with U.S. GAAP related matters, including income tax and inventory valuation. We will closely monitor the attrition of our accounting personnel and will maintain adequate human resources in financial reporting in the future. In addition, the Company is continuing to provide training programs related to SEC reporting and U.S. GAAP to our accounting and financial reporting personnel.

Changes in Internal Control

In our 2005 annual report on Form 20-F, we reported material weaknesses in our internal control over financial reporting in relation to (i) a lack of personnel with U.S. GAAP reporting experience, and (ii) the use of manual accounting systems that did not enable timely recording of transactions. In our attempt to remediate these previously reported material weaknesses and to enhance our overall control environment and corporate governance, we have undertaken significant efforts to strengthen our internal control over financial reporting and have implemented the following measures:

• We have established an internal audit department consisting of a director, who reports directly to our audit committee.

• Using the COSO framework as a guideline, we have designed and implemented internal control processes and procedures to improve our internal control over financial reporting. Such newly created processes and procedures have facilitated communications among our different departments and enabled us to formalize our control and procedures for financial reporting.

• We have provided training to our key employees regarding internal control processes and procedures and our Code of Business Conduct and Ethics.

• We officially launched our ERP system in January 2006, which allowed us to record transactions in a more timely and accurate manner.

Except for the remedial measures described above, there have been no significant changes in our internal control over financial reporting during the year ended December 31, 2006 that have materially affected, or a reasonably likely to materially affect, our internal control over financial reporting.

59

Critical Accounting Policies

We prepare financial statements in accordance with U.S. GAAP, which requires us to make judgments, estimates and assumptions that affect the reported amounts of our assets and liabilities and the disclosure of our contingent assets and liabilities at the end of each fiscal period and the reported amounts of revenues and expenses during each fiscal period. We continually evaluate these judgments and 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 assumptions that we believe to be reasonable, 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.

Our critical accounting policies, the judgments and other uncertainties affecting application of those policies and the sensitivity of reported results to changes in conditions and assumptions are factors that should be considered when reviewing our financial statements. We believe the following accounting policies involve the most significant judgments and estimates used in the preparation of our financial statements.

Revenue Recognition

We recognize revenue when persuasive evidence of an arrangement exists, delivery and transfer of title have occurred and the price is fixed or determinable and collectibility is reasonably assured. Under these criteria, revenue from the sale of our products is recognized net of accruals for estimated sales returns and allowances based on historical experience.

We extend credit terms only to a limited number of customers and receive cash for the majority of the sales transactions before we deliver our products which we record as advances from customers. For customers to which we provide credit terms, we have assessed a number of factors to determine whether collection from them is probable, including past transaction history with them and their credit-worthiness. If we determine that collection is not reasonably assured, we defer the recognition of revenue until collection becomes reasonably assured, which is generally upon receipt of payment.

We offer volume-based sales rebates to our customers on selected products when the customers have completed a specified cumulative level of revenue transactions. We accrue the cost of such rebates in accordance with EITF 01-9 “Accounting for Consideration Given by a Vendor to a Customer (Including a Reseller of the Vendor’s Product),” by reducing the underlying sales transactions that are instrumental to earning the rebates based on the estimated number of customers that will ultimately earn and claim the rebates.

Inventories

We state inventories at the lower of cost, on a weighted average basis, or market. Market value is equal to current replacement cost to the extent that it does not exceed net realizable value. We record adjustments to write down the cost of obsolete or excess inventory to the estimated net realizable value based on historical and forecasted demand. Determination of net realizable value of inventories involves numerous judgments, including projecting average selling prices and sales volumes for future periods and costs to complete products in work in process inventories. To project average selling prices and sales volumes, we review recent sales volumes, existing customer orders, current contract prices, industry analysis of supply and demand, seasonal factors, general

60

economic trends and other information. When these analyses reflect estimated market values below our manufacturing costs or the carrying value reflected in the balance sheet, we record a charge to cost of revenue in advance of when the inventory is actually sold. Differences in forecasted average selling prices used in calculating lower of cost or market adjustments can result in significant changes in the estimated net realizable value of product inventories and accordingly the amount of write-down recorded. Due to the volatile nature of the semiconductor industry, actual selling prices and volumes often vary significantly from projected prices and volumes and, as a result, the timing of when costs of revenue are charged to operations can vary significantly.

Share-based Compensation

Our share-based compensation plan is described in more detail under “Item 6. Directors, Senior Management and Employees.” We adopted SFAS 123R using the modified prospective transition approach from January 1, 2006. Prior to January 1, 2006, we accounted for share-based compensation arrangements with employees in accordance with the provisions of APB 25 “Accounting for Stocks Issued to Employees”, and related interpretations thereof. Pursuant to SFAS 123R, we recognized share-based compensation over the requisite service periods for any share option and restricted share granted after December 31, 2005 based on the fair value of the share option and restricted share on the date of grant. We continue to account for share options that had been granted prior to the initial public filing of our registration statement on Form F-1 with the SEC on October 24, 2005 and that remained unvested at December 31, 2005 under APB 25. For share-based awards granted after the initial public filing of our registration statement on Form F-1 but prior to January 1, 2006, the unvested compensation cost at the effective date of adoption of SFAS 123R is computed based on the grant date fair values of those awards.

We recognize share-based compensation using the accelerated method for all share-based awards issued prior to January 1, 2006. We have elected to recognize share-based compensation after the date of adoption of SFAS 123R using the straight-line method for all share-based awards issued after January 1, 2006, which results in the recognition of less share-based compensation in the first several years during the vesting period compared to that which would have been recognized had we used the accelerated method. Forfeitures were estimated based on historical experience and are periodically reviewed.

We account for share awards issued to non-employees in accordance with the provisions of SFAS 123R and EITF 96-18, Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services. Under SFAS 123R and EITF 96-18, we use the Black-Scholes option pricing model method to measure the value of options granted to non-employees at each reporting date to determine the appropriate charge to share-based compensation.

Depreciation of Property and Equipment

We depreciate our property and equipment at rates sufficient to write off their costs less accumulated impairment losses and estimated residual values over their estimated useful lives on a straight-line basis. We review the useful lives periodically to ensure that the method and rates of depreciation are consistent with the expected pattern of economic benefits from fixed assets. We

61

estimate the useful lives and the residual values of the fixed assets based on our historical experience with similar assets, taking into account anticipated technological changes. The depreciation expense in future periods will change if there are significant changes from previous estimates.

Impairment of Long-lived Assets

We assess the impairment of long-lived assets when events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Recoverability of assets to be held and used is measured by comparing the carrying amount of the assets to the estimated future undiscounted cash flows to be produced by the assets. If the total of the estimated future undiscounted cash flow is less than the carrying value, impairment is present and a loss is recognized in the statement of income for the difference between the fair value and the carrying value of the assets. The future undiscounted cash flow is based on management’s estimates and assumptions with respect to future revenues, cost of revenues and operating expenses. We cannot provide you with any assurances that actual results will be equal to our estimates. During the three years ended December 31, 2006, we did not record any impairment charges. If we make different judgments or adopt different assumptions, material differences could result in the amount and timing of any impairment charge that is recorded.

Deferred Tax Valuation Allowance

We record a valuation allowance to reduce our deferred tax assets if, based on an estimate of our future taxable income and prudent and feasible tax planning strategies, it is more likely than not that we will not be able to utilize our deferred tax asset amounts. Our estimated realization of our deferred tax assets is dependent on many factors, including our ability to generate taxable income within the period during which temporary differences reverse or before our tax loss carry-forwards expire, the outlook for the Chinese economy and overall outlook for our industry. If we make different judgments or adopt different assumptions, material differences could result in the amount and timing of any valuation allowance that is recorded.

Comparison of the Years Ended December 31, 2006 and 2005

Net Revenue. Our net revenue increased by US$31.3 million, or 32.8%, to US$126.6 million in 2006 from US$95.3 million in 2005. This increase was due primarily to (i) an increase in unit shipments of our PC and embedded notebook camera multimedia processors from 22.5 million units in 2005 to 35.5 million units in 2006, (ii) an increase in unit shipments of our mobile phone multimedia processors from approximately 10.7 million units in 2005 to approximately 18.6 million units in 2006, and (iii) an increase in unit shipments of image sensors from 13.6 million units in 2005 to 20.2 million units in 2006 as we bundled sensors with an increased volume of PC multimedia processors.

Cost of Revenue and Gross Profit. Cost of revenue increased by US$27.3 million, or 46.2%, to US$86.2 million in 2006 from US$58.9 million in 2005. This increase was due primarily to an increase in our sales volume. Our gross profit increased by US$4.1 million, or 11.1%, to US$40.4 million in 2006 from US$36.3 million in 2005. However, the gross profit margin dropped 6.2% from 38.1% in 2005 to 31.9% in 2006. This decrease was primarily due to a decline in average selling prices across all major product lines.

Operating Expenses. Operating expenses increased by US$14.2 million, or 73.9%, to US$33.5 million in 2006 from US$19.3 million in 2005. This increase was due primarily to (i) the increase in approximately US$5 million additional payroll and welfare expenses as R&D headcount increased, (ii) the increase of US$1.8 million in share-based compensation expenses due to the adoption of FAS-123R, and (iii) the increase of US$4.0 million audit, legal and consultant expense, including US$2.5 million expenses from the audit committee investigation and aborted secondary offering.

Research and Development. Research and development expenses increased by US$ 9.2 million, or 113.8%, to US$17.3 million in 2006 from US$8.1 million in 2005. Our gross research and development expenditures before government grant deduction increased US$10.6 million or 105.4% from US$10 million in 2005 to US$20.6 million in 2006. The increase mainly reflected i) the increase of approximately US$5 million payroll and welfare expenses as R&D headcount increased from 248 as of December 31, 2005 to 437 as of December 31, 2006, ii) the increase of US$1.8 million in share-based compensation expenses from US$520,000 in 2005 to

63

US$2.3 million in 2006, mainly due to the adoption of FAS123R, and iii) the approximately $1.0 million increase in depreciation of fixed assets and rental cost for office space. We expect that our total research and development expenses, including costs incurred in connection with hiring additional research and development staff and purchase of intellectual property, to increase as we continue to expand our portfolio of new multimedia products.

Sales and Marketing. Sales and marketing expenses increased by US$0.3 million, or 4.8%, to US$5.4 million in 2006 from US$5.1 million in 2005. The increase mainly reflected the increase in share-based employee compensation expenses, which were approximately US$304,000 in 2005 and approximately US$436,000 in 2006, respectively.

General and Administrative. General and administrative expenses increased by US$4.8 million, or 78.8 %, to US$ 10.9 million in 2006 from US$6.1 million in 2005. The increase mainly reflected the $1.5 million increase of audit, legal and consultant expenses, $2 million for the audit committee investigation expense, and approximately $540,000 for the proposed secondary offering.

Income Tax Expense. Income tax expenses decreased by approximately US$662,000 from US$1.2 million in 2005 to approximately US$530,000 in 2006. The decrease in tax expense was mainly due to the decrease in income before tax, the increase in additional deduction from qualifying research and development expenses in Vimicro China and the change of tax filing status from onshore to offshore for Vimicro Electronics.

Vimicro China was subject to a preferential tax rate of 10% and was qualified to take an additional deduction for qualifying research and development expenses in 2006.

In year 2006, Vimicro Electronics performed an offshore claim on its trading profits. All or at least part of the trading profits previously categorized as onshore sourced are in fact offshore in nature and therefore not taxable in Hong Kong. If the claim succeed, the profit tax rate of Vimicro Electronics should be zero in 2006 and thereafter. Vimicro Electronics had tax benefit of $201,000 in 2006 due to the reversal of deferred tax liabilities.

Net Income. We incurred a net income of US$9.7 million in 2006, as compared to a net income of US$16.4 million in 2005, mainly due to the lowered gross profit margin and the increase in operating expenses.

Comparison of the Years Ended December 31, 2005 and 2004

Net Revenue. Our net revenue increased by US$45.0 million, or 89.6%, to US$95.3 million in 2005 from US$50.3 million in 2004. This increase was due primarily to a 41.6% increase in unit shipments of our PC and embedded notebook camera multimedia processors from 15.9 million units in 2004 to 22.5 million units in 2005 and a substantial increase in unit shipments of our mobile phone multimedia processors from approximately 845,000 units in 2004 to approximately 10.7 million units in 2005 as we introduced four new PC and embedded notebook camera and mobile phone multimedia processor products and further expanded our market share. The increase was also attributable to significant growth in unit shipments of image sensors from 6.7 million units in 2004 to 13.6 million units in 2005 as we bundled sensors with an increased volume of PC and embedded notebook camera multimedia processors.

64

Cost of Revenue and Gross Profit. Cost of revenue increased by US$26.5 million, or 81.9%, to US$58.9 million in 2005 from US$32.4 million in 2004. This increase was mainly due to an increase in our sales volume and the associated costs to manufacture, assemble, test and deliver these products. The increase was also attributable to an increased number of image sensors purchased from third-party sensor manufacturers, partly offset by a decline in the average unit cost of sensors. The increase in cost of revenue was also partially offset by a decline in the average unit cost for wafers and a reduction in the cost of assembly and testing of PC and embedded notebook camera processors in 2005 compared with 2004. Our gross profit increased by US$18.4 million, or 103.5%, to US$36.3 million in 2005 from US$17.9 million in 2004. This increase in gross profit was primarily due to a substantial increase in sales volume of our mobile multimedia processors and PC and embedded notebook camera multimedia processors and reduced per-unit costs for wafer assembly and testing. This increase was offset by a slight decline in average selling prices of our proprietary products.

Operating Expenses. Operating expenses decreased by US$5.1 million, or 20.8%, to US$19.3 million in 2005 compared to US$24.4 million in 2004. This decrease was due primarily to a substantial decrease in share-based employee compensation charges, which were US$13.4 million in 2004 and decreased to US$1.4 million in 2005, but was partially offset by an increase in all other categories of operating expenses.

Research and Development. Research and development expenses, increased by US$1.8 million, or 28.8%, to US$8.1 million in 2005 from US$6.3 million in 2004, despite a substantial decrease in the share-based employee compensation charge relating to our research and development personnel by US$2.4 million from US$2.7 million in 2004 to US$249,000 in 2005. Our gross research and development expenditures (before government grant deduction and excluding share-based employee compensation expenses) increased US$3.9 million, or 66.1% from US$5.9 million in 2004 to US$9.8 million in 2005. This increase in our research and development expenditures was due to the increase in the number of our research and development personnel from 135 as of December 31, 2004 to 248 as of December 31, 2005 to staff an increased number of research projects. It was also attributable to a higher amount of expenses incurred to purchase research-related materials and lease expenses associated with research and development as well as the higher amount of rental expenses for occupancy associated with our research and development division. Our research and development expenses in 2004 included US$752,000 of expenses incurred by SPMC during the period. We disposed of our interest in SPMC in December 2004 and have not included any expenses incurred by SPMC in our operating expenses since that disposition. We applied US$1.9 million of government and private grants to offset our gross research and development expenses in 2005, as compared to US$2.3 million applied in 2004.

Sales and Marketing. Sales and marketing expenses decreased by US$2.0 million, or 28.1%, to US$5.1 million in 2005 from US$7.1 million in 2004, primarily due to a substantial decrease in the share-based compensation charge relating to our sales and marketing personnel by US$3.6 million from US$3.9 million in 2004 to US$0.3 million in 2005. The decrease was offset by increased compensation paid to sales and marketing personnel and increased promotion and advertising expenses incurred in 2005.

General and Administrative. General and administrative expenses decreased by US$4.8 million, or 44.2%, to US$6.1 million in 2005 from US$10.9 million in 2004, primarily due to a substantial decrease in the share-based compensation charge relating to our

65

general and administrative personnel by US$5.9 million from US$6.8 million in 2004 to US$0.9 million in 2005. The decrease was offset by an increase in the cost of third-party professional services incurred in connection with our efforts to improve our accounting and reporting systems and to strengthen our internal controls over financial reporting. General and administrative expenses in 2004 included US$594,000 of general and administrative expenses incurred by SPMC during the period.

Income Tax Expense. Income tax expenses increased by US$1.0 million from US$221,000 in 2004 to US$1.2 million in 2005. Although we incurred a net loss in 2004, we were still subject to income tax liabilities in various tax jurisdictions because the share-based compensation recorded was not a tax deductible expense. The effective tax rate was 6.8% for the year ended December 31, 2005, which resulted from our taxable income generated in 2005. We incurred a majority of our income tax expense in the PRC. Vimicro China was subject to a preferential tax rate of 7.5% and was qualified to take an additional deduction for qualifying research and development expenses in 2005.

Minority Interest. Minority interest represents the share of the net loss of SPMC attributable to the other SPMC joint venture partners prior to the termination of the joint venture in December 2004. Minority interest amounted to US$0.9 million in 2004. We disposed of our interest in SPMC in December 2004 and no longer record minority interest relating to SPMC. There was no minority interest in 2005.

Net Income (Loss). We earned net income of US$16.4 million in 2005, as compared to a net loss of US$5.6 million in 2004, due primarily to a US$13.4 million share-based employee compensation expenses recorded in 2004.

B. Liquidity and Capital Resources

We have financed our operations primarily through private sales of equity interests to investors, the proceeds of our initial public offering as well as through cash generated from our operating activities. We have also received government and private grants to fund our research and development projects. Our principal use of cash for the three years ended December 31, 2006 was to fund our working capital requirements. As of December 31, 2006, we had US$114.8 million in cash. Our cash consists of cash on hand and bank deposits with terms of three months or less.

We expect that our net working capital requirements will increase as we offer longer payment terms to attract and retain large customers, including customers for our mobile phone multimedia processors. We plan to fund this increase in working capital requirement from our operating cash inflow and existing cash reserve.

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

	Year Ended December 31,
	2004		2005		2006
	(in US$ thousands)
Net cash provided by operating activities	7,499		7,589		19,314
Net cash provided by (used in) investing activities	(1,729	)	(3,764	)	(6,617	)
Net cash provided by financing activities	22,715		62,160		1,141
Effect of exchange rate changes on cash			33		386
Net increase in cash	28,485		66,018		14,224
Cash at beginning of year	6,107		34,592		100,610
Cash at end of year	34,592		100,610		114,834

66

Net cash provided by operating activities in 2006 was US$19.3 million, primarily as a result of our operating profit in 2006, and a decrease of US$9.5 million in inventory. Net cash provided by operating activities amounted to US$7.6 million in 2005, primarily as a result of our operating profit in 2005, and to a lesser extent, an increase in accrued expenses and other current liabilities which consisted primarily of professional services fees. This increase was offset in part by an increase in accounts receivables and an increase of our inventory to support our increased sales volume in 2005. Net cash provided by operating activities amounted to US$7.5 million in 2004, primarily as a result of our operating profit before giving effect to the share-based employee compensation expenses incurred in 2004, and to a lesser extent, an increase in accrued expenses and other current liabilities which consisted primarily of professional services fees and year-end bonuses to executives and other employees. This increase was offset in part by an increase in inventories to support our increased sales volume in 2004.

Net cash used in investing activities was US$6.6 million in 2006, primarily due to the increase of approximately $6.6 million purchase of fixed assets, mainly development tools, mask tooling, software, and other equipment. Net cash used in investing activities amounted to US$3.8 million in 2005 and US$1.7 million in 2004, primarily due to a substantial increase in our expenditures for the purchase of software, development tools and computer equipment to meet the demand of our growing business and operations in each of 2005 and 2004.

Net cash provided by financing activities was US$1.1 million in 2006, primarily due to the exercise of share options. Net cash provided by financing activities amounted to US$62.2 million in 2005, primarily due to the proceeds from our initial public offering which amounted to US$59.1 million, and from shares sold in connection with the exercise of share options in 2005. Net cash provided by financing activities amounted to US$22.7 million in 2004, primarily due to the proceeds from the private placement of our preferred shares in 2004, offset in part by the amount we used to repay a short-term bank loan.

We believe that our current cash, cash flow from operations and the proceeds from the initial public offering will be sufficient to meet our anticipated cash needs, including our working capital requirements and capital expenditures for at least the next 12 months. Our future cash requirements will depend on many factors, including our level of operating income, the timing of our new product introductions, the costs to secure access to adequate manufacturing capacity, the continuing market acceptance of our products, or other 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 banks.

67

Capital Expenditures

Our capital expenditures amounted to US$2.0 million, US$3.8 million and US$6.6 million in 2004, 2005 and 2006, respectively. In the past, our capital expenditures consisted principally of purchases of software, development tools, computer equipment and other items related to our product development activities. We estimate that we will make capital expenditures in 2007 between $5 million and $6 million (excluding the property expenditure), which will be used primarily to the purchases of software, development tools and other items related to our product development activities. In the five months ended May 31, 2007, we spent approximately $3.8 million on the capital expenditures.

In December 2006, Vimicro China entered into an agreement with Beijing Haidian Xinhua Agricultural Industrial & Commercial Co. to acquire the land-use rights for approximately 29,000 square meters of land (including a construction site area of approximately 7,900 square meters) in Haidian District, Beijing. The land will be the site of a new building, which will become Vimicro China’s new headquarters and accommodate a research and development center. The aggregate consideration for the acquisition of the land-use rights and the construction of the new building is estimated to be approximately US$38.3 million. The proposed project, including the gross land area and construction site area, is subject to governmental approval. Should the governmental authorities request us to modify the project, the land and construction site areas, as well as the total cost for the project, may change. It is estimated that the construction of this new building will be completed by 2009.

On June 27, 2007, we entered into an agreement with Shenzhen Municipal Bureau of Land Resources and Housing Management, pursuant to which, in consideration of approximately US$856,000, we acquired land use rights for approximately 3,947 square meters of land in Shenzhen High-Tech Industrial Park. The land will be the site of a new building, which will become Vimicro Technology’s office building and accommodate a research and development center. Governmental authorities would require us to obtain necessary governmental approvals for the proposed project. It is estimated that the construction of this new building will be completed by 2009.

C. Research and Development

We maintain a team of experienced engineers. As of December 31, 2006, our research and development staff consisted of 437 engineers, representing approximately 74% of the total number of our employees. Most of our senior engineers have work experience in research institutions or technology companies in Silicon Valley. Going forward, we intend to recruit most of our engineers in China. We have established various recruiting and training programs with leading universities in China. In addition, we will also selectively recruit experienced engineers from Silicon Valley. Our research and development staff is divided into four teams: semiconductor development, software/firmware development, system design, and management and support. Our engineers work with our customers’ system design, engineering and procurement groups to identify future product needs. Through these efforts, we seek to introduce new products to address new market opportunities, to continue to reduce our design cost and to improve the cost effectiveness and performance of our products and solutions.

Our gross expenditures on research and development before offsetting research grants amounted to US$8.6 million, US$10.0 million and US$20.6 million in 2004, 2005 and 2006, respectively.

H. Recent Accounting Pronouncements

In September 2006, the FASB issued Statement of Financial Accounting Standards No.157, “Fair Value Measurements” (“SFAS 157”), which defines fair value, establishes guidelines for measuring fair value and expands disclosures regarding fair value measurements. SFAS 157 does not require any new fair value measurements but rather eliminates inconsistencies in guidance found in various prior accounting pronouncements. SFAS 157 will be effective for the Company starting January 1, 2008. Earlier adoption is permitted, provided the company has not yet issued financial statements, including for interim periods, for that fiscal year. The Company is currently evaluating the impact of SFAS 157 on its consolidated financial position, cash flows and results of operations.

In July 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement No. 109” (“FIN 48”), which clarifies the accounting for uncertainty in tax positions. This Interpretation requires that the Company recognize and disclose in its financial statements the impact of a tax position if that position is more likely than not of being sustained on audit, based on the technical merits of the position. The provisions of FIN 48 became effective for the Company on January 1, 2007, with the cumulative effect of the change in accounting principle, if any, recorded as an adjustment to opening retained earnings. The Company has evaluated the impact of FIN 48 and believes that it has no material impact on its consolidated financial position, cash flows and results of operations.

70

In June 2006, the FASB ratified the provisions of the Emerging Issue Task Force Issue No. 06-3 “How Sales Taxes Collected from Customers and Remitted to Governmental Authorities Should Be Presented in the Income Statement” (“EITF 06-3”), which requires the Company to disclose how it accounts for taxes imposed on and concurrent with a specific revenue-producing transaction. EITF 06-3 will be effective for the Company starting January 1, 2007. The Company does not believe that the application of EITF 06-03 will have a material effect on its financial position.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”). SFAS 159 permits companies and not-for-profit organizations to make a one-time election to carry eligible types of financial assets and liabilities at fair value, even if fair value measurement if not required under U.S. GAAP. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company does not believe that the adoption of SFAS 159 will have a significant impact on its financial position, result of operations or cash flows.

In connection with our reorganization, we issued options pursuant to Vimicro China’s prior commitments. The

74

following table summarizes, as of March 31, 2007, the outstanding historical options granted to our directors and executive officers named below and to other individuals including our employees, consultants and advisors.

	Ordinary Shares Underlying Options Granted	Exercise Price (US$ per share)	Date of Grant	Date of Expiration
Xiaodong Yang	1,200,000	0.60	March 17, 2004	March 17, 2014
Jun Zhu	75,000	0.60	March 17, 2004	March 17, 2014

Other individuals as a group	3,346,500	From 0.01 to 0.60	March 17, 2004	March 17, 2014

The vesting schedule of the options we granted in March 2004 was determined based on the optionee’s length of employment with or services to us and the date on which Vimicro China initially promised to grant options to such optionee.

2004 Share Option Plan. Our board of directors adopted a 2004 share option plan, or the 2004 plan, which is intended to attract and retain the best available personnel for positions of substantial responsibility, provide additional incentive to employees, directors and consultants and promote the success of our business. We have reserved 12,541,080 of our ordinary shares for issuance under the 2004 plan. The 2004 Plan was terminated in October 2005, and the remaining options available for grant were transferred to the 2005 Share Incentive Plan. The following paragraphs describe the principal terms of the 2004 plan.

Termination of Options. Where the option agreement permits the exercise or purchase of the options granted for a certain period of time following the recipient’s termination of service with us, or the recipient’s disability or death, the options will terminate to the extent not exercised or purchased on the last day of the specified period or the last day of the original term of the options, whichever occurs first.

Administration. The 2004 plan is administered by our board of directors or a committee designated by our board of directors. In each case, our board of directors or the committee it designates will determine the provisions, terms and conditions of each option grant, including, but not limited to, the option vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions, form of payment upon settlement of the award, payment contingencies and satisfaction of any performance criteria.

Vesting Schedule. In general, options granted under the 2004 plan vest over a five-year period following a specified vesting commencement date. 20% of the options granted vest at the end of each year beginning from the first year anniversary of the vesting commencement date, subject to the optionee continuing to be an employee or a service provider on each vesting date.

Option Agreement. Options granted under the 2004 plan are evidenced by an option agreement that contains, among other things, provisions concerning exercisability and forfeiture upon termination of employment or consulting arrangement, as determined by our board. In addition, the option agreement also provides that options granted under the 2004 plan are subject to a 180-day lock-up period following the effective date of a registration statement filed by us under the Securities Act, if so requested by us or any representative of the underwriters in connection with any registration of the offering of any of our securities.

75

Option Exercise. The term of options granted under the 2004 plan may not exceed ten years from the date of grant. The consideration to be paid for our shares upon exercise of an option or purchase of shares underlying the option will be determined by the share option plan administrator and may include cash, check, ordinary shares, a promissory note, consideration received by us under a cashless exercise program implemented by us in connection with the 2004 plan, or any combination of the foregoing methods of payment.

Third-Party Acquisition. If a third party acquires us through the purchase of all or substantially all of our assets, a merger or other business combination, all outstanding options or share purchase rights will be assumed or equivalent options or rights will be substituted by the successor corporation or parent or subsidiary of successor corporation. In the event that the successor corporation refuses to assume or substitute for the options or share purchase rights, all options or share purchase rights will become fully vested and exercisable immediately prior to such transaction.

Termination of Plan. Unless terminated earlier, the 2004 plan will expire in 2009. Our board of directors has the authority to amend or terminate the 2004 plan subject to shareholder approval to the extent necessary to comply with applicable law and regulations. However, no such action may (i) impair the rights of any optionee unless agreed by the optionee and the share option plan administrator, or (ii) affect the share option plan administrator’s ability to exercise the powers granted to it under our share option plan.

The following table summarizes, as of March 31, 2007, the outstanding options granted to our directors and executive officers named below and to other individuals as a group pursuant to the 2004 plan.

Dr. Zhang is currently serving as our company’s advisor and consultant. Our board of directors has approved the grant of 200,000 restricted shares and options to purchase 800,000 ordinary shares at an exercise price of US$1.60 per share, subject to a three year vesting period, to Dr. Zhang for his services to our company after July 31, 2006.

76

(2) In connection with Xiaosong Zhang’s resignation on January 31, 2007, his unvested options to purchase 820,000 ordinary shares were cancelled.

2005 Share Incentive Plan. In October 2005, our board of directors and shareholders adopted a 2005 share incentive plan, or the 2005 plan. In December 2006, our board of directors and shareholders amended the 2005 plan to increase the maximum aggregate number of awards to 21,065,505 ordinary shares. We have reserved for issuance 21,065,505 ordinary shares upon exercise of awards granted under our 2005 plan.

Types of Awards. We may grant the following types of awards under our 2005 plan:

• our ordinary shares;

• options to purchase our ordinary shares;

• restricted shares, which are non-transferable ordinary shares, that may be subject to forfeiture;

• restricted share units, which represent the right to receive our ordinary shares at a specified date in the future, which may be subject to forfeiture;

• share appreciation rights, which provide for payment to the grantee based upon increases in the price of our ordinary shares over a set base price; and

• dividend equivalent rights, which represent the value of the dividends per share that we pay.

Awards may be designated in the form of ADSs instead of ordinary shares. If we designate an award in the form of ADSs, the number of shares issuable under the 2005 plan will be adjusted to reflect a ratio of one ADS to four ordinary shares.

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 stock options, or ISOs, only to our employees and employees of our majority owned subsidiaries.

Plan Administration. Our board of directors, or a committee designated by our board or directors, will administer the 2005 plan. However, with respect to awards made to our non-employee directors and executive officers, the entire board of directors will administer the 2005 plan. The committee or the full board of directors, as appropriate, will determine the individuals who will receive grants, the types of awards to be granted and terms and conditions of each award grant, including any vesting or forfeiture restrictions.

Award Agreement. Awards granted under our 2005 plan are evidenced by an award agreement that sets forth the terms, conditions and limitations for each award. In addition, in the case of options, the award agreement also specifies whether the option constitutes an ISO or a non-qualifying stock option.

77

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 under the 2005 plan. In such event, each outstanding award will become fully vested and immediately exercisable, and the transfer restrictions on the awards will be released and any forfeiture provisions will terminate immediately before the date of the change-of-control transaction. If the successor entity assumes our outstanding awards and later terminates the grantee’s service without cause within 12 months of the change-of-control transaction, the outstanding awards automatically become fully vested and exercisable.

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 ordinary shares. However, ISOs may not be granted at an exercise price which is less than the fair market value of our ordinary shares on the date of grant. Also, if we grant an ISO 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 ordinary shares on 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, except that five years is the maximum term of an ISO granted to an employee who holds more than 10% of the voting power of our share capital.

Amendment and Termination. Our board of directors may at any time amend, suspend or terminate the 2005 plan. Amendments to the 2005 plan are subject to shareholder approval to the extent required by law, or stock exchange rules or regulations. Additionally, shareholder approval will be specifically required to increase the number of shares available for issuance under the 2005 plan or to extend the term of an option beyond ten years. Unless terminated earlier, the 2005 plan will expire and no further awards may be granted after the tenth anniversary of the shareholder approval of the 2005 plan.

Grant of Restricted Shares. We granted 802,600 restricted shares under the 2005 plan. Key terms in the award agreements are summarized as follow:

• The restricted shares will vest approximately according to the following schedules:

40% of the restricted shares will vest two years after the grant date, and 10% of the shares will vest semi-annually thereafter over the next three years.

or

20% of the restricted shares will vest one year after the grant date, and 10% of the shares will vest semi-annually thereafter over the next four years.

• The unvested portion of the restricted shares are subject to forfeiture upon the termination of the holder’s employment with or service to us;

• Until vested, the restricted shares are not transferable and may not be sold, pledged or otherwise transferred.

C. Board Practices

Our board of directors consists of nine directors. A director is not required to hold any of our shares by way of qualification. A director may vote with respect to any contract,

79

proposed contract or arrangement in which he is materially interested. A director may exercise all the powers of the company to borrow money, mortgage its undertaking, property and uncalled capital, and issue debentures or other securities whenever money is borrowed or as security for any obligation of the company or of any third party.

Committees of the Board of Directors

We have established three committees under the board of directors — the audit committee, the compensation committee and the corporate governance and nominating committee. We have adopted a charter for each of the committees. Each committee’s members and functions are described below.

Audit Committee. Our audit committee consists of Messrs. Donald L. Lucas, Robert Chen and Yingyi Qian. Messrs. Lucas, Chen and Qian satisfy the “independence” requirements of the Nasdaq Marketplace Rules. The audit committee oversees our accounting and financial reporting processes and the audits of the financial statements of our company. The audit committee is responsible for, among other things:

• selecting the independent auditors and pre-approving all auditing and non-auditing services permitted to be performed by the independent auditors;

• reviewing with the independent auditors any audit problems or difficulties and management’s response;

• reviewing and approving all proposed related-party transactions, as defined in Item 404 of Regulation S-K;

• discussing the annual audited financial statements with management and the independent auditors;

• reviewing major issues as to the adequacy of our internal controls and any special audit steps adopted in light of material control deficiencies;

• annually reviewing and reassessing the adequacy of our audit committee charter;

• such other matters that are specifically delegated to our audit committee by our board of directors from time to time;

• meeting separately and periodically with management and the independent auditors; and

• reporting regularly to the full board of directors.

In 2006, our audit committee held meetings or passed resolutions by unanimous written consent thirteen times.

Compensation Committee. Our compensation committee consists of Messrs. Robert Chen and Theodore Van Duzer. Messrs. Chen and Van Duzer satisfy the “independence” requirements of the Nasdaq corporate governance rules. Our compensation committee assists the board in reviewing and approving the compensation structure of our directors and executive officers, including all forms of compensation to be provided to our directors and executive officers. Our chief executive officer may not be present at any committee meeting during which his compensation is deliberated. The compensation committee is responsible for, among other things:

• reviewing and recommending to the board with respect to the total compensation package for our four most senior executives;

80

• approving and overseeing the total compensation package for our executives other than the four most senior executives;

• reviewing and making recommendations to the board with respect to the compensation of our directors; and

• reviewing periodically and approving any long-term incentive compensation or equity plans, programs or similar arrangements, annual bonuses, employee pension and welfare benefit plans.

In 2006, our compensation committee held meetings or passed resolutions by unanimous written consent eight times.

Corporate Governance and Nominating Committee. Our corporate governance and nominating committee consist of Messrs. Donald L. Lucas and Theodore Van Duzer. Messrs. Lucas and Van Duzer satisfy the “independence” requirements of the Nasdaq corporate governance rules. 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. The corporate governance and nominating committee is responsible for, among other things:

• identifying and recommending to the board nominees for election or re-election to the board, or for appointment to fill any vacancy;

• reviewing annually with the board the current composition of the board in light of the characteristics of independence, age, skills, experience and availability of service to us;

• identifying and recommending to the board the names of directors to serve as members of the audit committee and the compensation committee, as well as the corporate governance and nominating committee itself;

• advising the board periodically with respect to significant developments in the law and practice of corporate governance as well as our compliance with applicable laws and regulations, and making recommendations to the board on all matters of corporate governance and on any corrective action to be taken; and

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

In 2006, our corporate governance and nominating committee held meetings or passed resolutions by unanimous written consent four times.

Duties of Directors

Under Cayman Islands law, our directors have a duty of loyalty to act honestly in good faith with a view to our best interests. Our directors also have a duty to exercise the skill they actually possess and such care and diligence that a reasonably prudent person would exercise in comparable circumstances. In fulfilling their duty of care to us, our directors must ensure compliance with our memorandum and articles of association. Our articles of association govern the way our company is operated and the powers granted to the directors to manage the daily affairs of our company. A shareholder has the right to seek damages if a duty owed by our directors is breached.

Terms of Directors and Officers

All directors hold office until their successors have been duly elected and qualified. Our shareholders may remove any director by special resolution before the expiration of his or her term and may by ordinary resolution appoint another person to fill the vacancy. A valid ordinary resolution requires the votes of a majority of shareholders attending the shareholder meeting that is duly constituted and meets the quorum requirement. Officers are elected by and serve at the discretion of the board of directors.

D. Employees

We had 215, 369 and 588 employees as of December 31, 2004, 2005 and 2006, respectively. As of December 31, 2006, we had 88 employees in management and administration, 437 employees in research and development and 63 employees in sales and marketing.

E. Share Ownership

As of March 31, 2007, the most recent practicable date, 139,821,474 of our ordinary shares were outstanding, excluding shares issuable upon exercise of outstanding options and 793,155 restricted shares. On that date, a total of 21,843,157 of our ADSs were outstanding. Our shareholders are entitled to vote together as a single class on all matters submitted to shareholders vote. Except for holders of 793,155 restricted shares, no shareholder has different voting rights from other shareholders. We are not aware of any arrangement that may, at a subsequent date, result in a change of control of our company.

ITEM 7. MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS

A. Major Shareholders

Please refer to “Item 6. Directors, Senior Management and Employees — Share Ownership.”

B. Related Party Transactions

Reorganization

In anticipation of our issuance and sale of preferred shares to a group of international investors through a private placement, in March 2004, we entered into a Shareholding Transfer Agreement with each former owner of Vimicro China and a Reorganization and Subscription Agreement with each such former owner and/or its designated nominee to carry out our reorganization. Pursuant to these agreements, the following transactions were consummated:

• All the former owners of Vimicro China obtained requisite approvals from the local governmental authorities to transfer their equity interests in Vimicro China to Vimicro International Corporation in May 2004. As a result, Vimicro China became our wholly-owned subsidiary in May 2004.

• In consideration for the share transfer in May 2004 by each former owner of Vimicro China who was not a PRC entity or resident, or non-PRC shareholder, on October 13, 2004, Vimicro International Corporation issued a total of 14,437,500 ordinary shares to each non-PRC shareholder and/or its designated nominee, based on such non-PRC shareholder’s pro rata interest in Vimicro China prior to the reorganization.

• Under applicable PRC law, Vimicro International Corporation was required to pay cash to each former owner of Vimicro China who was a PRC entity or resident, or PRC shareholder, in consideration for the transfer of its ownership interest in Vimicro China in May 2004. Shortly after the completion of its issuance and sale of preferred shares on October 12, 2004, Vimicro International Corporation paid a total cash consideration of US$8.4 million, as determined under applicable PRC law, to these PRC shareholders, using part of the proceeds from its issuance and sale of preferred shares.

• On November 19, 2004, each PRC shareholder and/or its designated nominee used the same amount of cash previously received from Vimicro International Corporation to subscribe for a total of 67,709,400 ordinary shares of Vimicro International Corporation. The number of ordinary shares issued and sold to each individual PRC shareholder or designated nominee was based on the PRC shareholder’s pro rata interest in Vimicro China prior to the reorganization.

85

Private Placement

In October 2004, we issued an aggregate of 15,217,150 preferred shares in a private placement at a price of US$1.5977 per share to a group of investors, including General Atlantic, Fujitsu Microelectronics Asia Pte Ltd, Capital Group Resources Ltd., Gartner Technology Ltd., Millennium Project Development and Donald L. Lucas, our director. Each preferred share was automatically converted into one ordinary upon completion of our initial public offering.

Registration Rights Agreement

In connection with our private placement in October 2004, we entered into a registration rights agreement with General Atlantic. We have granted General Atlantic customary registration rights, including demand and piggyback registration rights and Form F-3 registration rights. For a detailed description of these rights, see “Description of Share Capital—Registration Rights.”

ITEM 8. FINANCIAL INFORMATION

A. Consolidated Statements and Other Financial Information

We have appended consolidated financial statements filed as part of this annual report.

Legal Proceedings

In April 2006, our auditors received two anonymous letters purportedly written by certain shareholders. The letters included allegations relating to option grants to our founders and activities at our U.S. subsidiary five and six years ago. In response to the letters, our board of directors asked our audit committee, consisting of independent, non-management directors, to conduct a review of the issues raised by the letters. After a two and one half month review and assisted by our special outside legal counsel, our audit committee did not find evidence to substantiate the allegations in the anonymous letters, other than with respect to a single transaction recorded by our U.S. subsidiary in 2001, which was reversed in 2002. Our audit committee concluded that the impact of that transaction on our prior financial statements was not material. No legal claims have been made against us, but we intend to contest them if such claims are made.

From time to time, we may be involved in litigation or other legal proceedings incidental to our business. We are not aware of any material legal proceedings currently existing or pending against us that will have a material adverse effect on our business and results of operations. Regardless of the outcome, however, any litigation or other legal proceedings can result in substantial costs and diversion of management resources and attention.

86

Dividend Policy

We have never declared or paid any dividends, nor do we have any present plan to pay any cash dividends on our ordinary 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 as to whether to distribute dividends. Even if our board of directors decides to pay dividends, the timing, amount and form of future dividends, if any, will depend on, among other things, our future results of operations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiary Vimicro China, our financial condition, contractual restrictions and other factors deemed relevant by our board of directors.

If we pay any dividends, we will pay our ADS holders to the same extent as holders of our ordinary shares, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder. See “Description of American Depositary Shares.” Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.

B. Significant Changes

We have not experienced any significant changes since the date of our audited consolidated financial statements included in this annual report.

We have not entered into any material contracts other than in the ordinary course of business and other than those described in “Item 4. Information on the Company” or elsewhere in this annual report on Form 20-F.

D. Exchange Controls

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

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

88

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

Under the Exchange Rules, the RMB is convertible for current account items, including the distribution of dividends, interest payments, trade and service-related foreign exchange transactions. Conversion of RMB for capital account items, such as direct investment, loan, security investment and repatriation of investment, however, is still subject to the approval of the SAFE.

Under the Administration Rules, foreign-invested enterprises may only buy, sell or remit foreign currencies at those banks authorized to conduct foreign exchange business after providing valid commercial documents and, in the case of 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 Development and Reform Commission.

E. Taxation

Cayman Islands Taxation

According to Maples and Calder, our Cayman Islands counsel, the Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us levied by the Government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or brought within the jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties. There are no exchange control regulations or currency restrictions in the Cayman Islands.

United States Federal Income Taxation

The following discussion describes the material United States federal income tax consequences to U.S. Holders (defined below) under present law of an investment in the ADSs or ordinary shares. This summary applies only to investors that hold the ADSs or ordinary 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 Form 20-F and on United States Treasury regulations in effect or, in some cases, proposed, as of the date of this Form 20-F, 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;

• financial institutions;

• insurance companies;

89

• broker dealers;

• traders that elect to mark to market;

• tax-exempt entities;

• persons liable for alternative minimum tax;

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

• persons that actually or constructively own 10% or more of our voting shares; or

• persons holding ADSs or ordinary shares through partnerships or other pass-through entities; or

• persons who acquired ADSs or ordinary shares pursuant to the exercise of any employee share option or otherwise as consideration.

U.S. Holders are urged to consult their tax advisors about the application of the United States 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 ADSs or ordinary shares.

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

• a citizen or individual resident of the United States;

• a corporation (or other entity taxable as a corporation for United States 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 United States 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 United States persons or (2) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

The discussion below assumes that the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms. If you hold ADSs, you will be treated as the holder of the underlying ordinary shares represented by those ADSs for United States federal income tax purposes.

The U.S. Treasury has expressed concerns that parties to whom ADSs are pre-released may be taking actions that are inconsistent with the claiming, by U.S. Holders of ADSs, of foreign tax credits for United States federal income tax purposes. Such actions would also be inconsistent with the claiming of the reduced rate of tax applicable to dividends received by certain

90

non-corporate U.S. Holders, as described below. Accordingly, the availability of the reduced tax rate for dividends received by certain non-corporate U.S. Holders could be affected by future actions that may be taken by the U.S. Treasury or parties to whom ADSs are pre-released.

Taxation of Dividends and Other Distributions on the ADSs or Ordinary Shares

Subject to the passive foreign investment company rules discussed below, the gross amount of all our distributions to you with respect to the ADSs or ordinary shares will be included in your gross income as dividend income on the date of receipt by the depositary, in the case of ADSs, or by you, in the case of ordinary shares, but only to the extent that the distribution is paid out of our current or accumulated earnings and profits (computed under United States federal income tax principles). 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 be taxed at the lower applicable capital gains rate (“qualified dividend income”) provided that (1) the ADSs or ordinary 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, and (3) certain holding period requirements are met. Under published Internal Revenue Service authority, common or ordinary shares, or ADSs representing such shares, are considered for 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. The ADSs are traded on the NASDAQ Global Market. You should consult your tax advisor regarding the availability of the lower rate for dividends paid with respect to our ADSs or ordinary shares.

Dividends will constitute foreign source income for foreign tax credit limitation purposes. 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 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 the ADSs or ordinary shares will be “passive income” or, in the case of certain U.S. Holders, “financial services income.” For taxable years beginning after December 31, 2006, dividends distributed by us with respect to ADSs or ordinary shares generally would constitute “passive category income” but could, in the case of certain U.S. Holders, constitute “general category income.”

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 ADSs or ordinary 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 for United States federal income tax purposes. Therefore, a U.S. Holder should expect that a distribution will be reported as a dividend.

91

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 an ADS or ordinary share equal to the difference between the amount realized (in U.S. dollars) for the ADS or ordinary share and your tax basis (in U.S. dollars) in the ADS or ordinary 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 ADS or ordinary 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 United States source income or loss (in the case of losses, subject to certain limitations).

Passive Foreign Investment Company

We believe that for our taxable year ended December 31, 2006, we were not a passive foreign investment company (“PFIC”) for United States federal income tax purposes. However, our PFIC status for the current taxable year ending December 31, 2007 will not be determinable until its close, 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 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 shares.

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 generally will be calculated using the market price of our ADSs and ordinary shares, our PFIC status will depend in large part on the market price of our ADSs and ordinary shares which may fluctuate considerably. Accordingly, fluctuations in the market price of the ADSs and ordinary shares may result in our being a PFIC for any year. In addition, the composition of our income and assets is affected by how, and how quickly, we spend the cash we raise in any offering. If we are a PFIC for any year during which you hold ADS or ordinary shares, we will continue to be treated as a PFIC for all succeeding years during which you hold ADS or ordinary shares.

If we are a PFIC for any taxable year during which you hold ADSs or ordinary 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 ADSs or ordinary 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 ADSs or ordinary 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 ADSs or ordinary shares,

92

• 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 taxable year will be subject to the highest tax rate in effect for that taxable year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such taxable 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 ADSs or ordinary shares cannot be treated as capital, even if you hold the ADSs or ordinary shares as capital assets.

Alternatively, a U.S. Holder of “marketable stock” (as defined below) in a PFIC may make a mark-to-market election for such stock of a PFIC to elect out of the tax treatment discussed in the two preceding paragraphs. If you make a mark-to-market election for the ADSs or ordinary shares, you will include in income each year an amount equal to the excess, if any, of the fair market value of the ADSs or ordinary shares as of the close of your taxable year over your adjusted basis in such ADSs or ordinary shares. You are allowed a deduction for the excess, if any, of the adjusted basis of the ADSs or ordinary 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 ADSs or ordinary 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 ADSs or ordinary shares, are treated as ordinary income. Ordinary loss treatment also applies to the deductible portion of any mark-to-market loss on the ADSs or ordinary shares, as well as to any loss realized on the actual sale or disposition of the ADSs or ordinary shares, to the extent that the amount of such loss does not exceed the net mark-to-market gains previously included for such ADSs or ordinary shares. Your basis in the ADSs or ordinary shares will be adjusted to reflect any such income or loss amounts. If you make a mark-to-market election, tax rules that apply to distributions by corporations which are not PFICs would apply to distributions by us (except that the lower applicable capital 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 or other market, as defined in applicable Treasury regulations. We expect that the ADSs will continue to be listed on the NASDAQ Global Market, which is a qualified exchange for these purposes, and, consequently, if you are a holder of ADSs, it is expected that the mark-to-market election would be available to you were we to become a PFIC.

If you hold ADSs or ordinary 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 ADSs or ordinary shares and any gain realized on the disposition of the ADSs or ordinary shares.

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

93

Information Reporting and Backup Withholding

Dividend payments with respect to ADSs or ordinary shares and proceeds from the sale, exchange or redemption of ADSs or ordinary shares may be subject to information reporting to the Internal Revenue Service and possible United States 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 must provide such certification on Internal Revenue Service Form W-9. U.S. Holders should consult their tax advisors regarding the application of the United States information reporting and backup withholding rules.

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

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Our exposure to interest rate risk primarily relates to the interest income generated by excess cash invested in demand and time deposits. We have not historically used and do not expect to use in the future, any derivative financial instruments to manage our interest risk exposure. Interest-earning instruments carry a degree of interest rate risk. We have not been exposed nor do we anticipate being exposed to material risks due to changes in interest rates.

Foreign Exchange Risk

The value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in China’s political and economic conditions. The conversion of RMB into foreign currencies, including U.S. dollars, has been based on rates set by the People’s Bank of China. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the RMB to the U.S. dollar. Under the new policy, the RMB 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 3% appreciation of the RMB against the U.S. dollar by the end of 2006. While the international reaction to the RMB 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 RMB against the U.S. dollar. A portion of our net revenue and most of our operating expenses are denominated in RMB, while most of our revenue, cost of revenue and non-operating expenses are denominated in U.S. dollars and Hong Kong dollars, which are pegged to the U.S. dollar. We use the U.S. dollar as the reporting currency for our financial statements. Fluctuations in exchange rates, primarily those involving the U.S. dollar, may affect our costs and operating margins as well as our net income reported in U.S. dollars. For example, to the extent that we need to convert U.S. dollars we receive from our initial public offering into RMB for our operations, appreciation of the RMB against the U.S. dollar would have an adverse effect on the RMB amount we receive from the conversion. Assuming we had converted the U.S. dollar, HK dollar and New Taiwan dollar denominated cash balance equivalent to US$98.8 million as of December 31, 2006 into RMB at the exchange rate of US$1.00 for RMB7.8087 and HKD1.00 for RMB1.0047 as of December 29, 2006, this cash balance would have been RMB771.7 million. Assuming a further 10% appreciation of the RMB against the U.S. dollar, this cash balance would have decreased to RMB694.5 million as of December 31, 2006. Conversely, if we decide to convert our RMB into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the RMB would have a negative effect on the U.S. dollar amount available to us. We have not used any forward contracts or currency borrowings to hedge our exposure to foreign currency exchange risk.

95

Inflation

Since our inception, inflation in China has not materially impacted on our results of operations. According to the National Bureau of Statistics of China, the change in the consumer price index in China was 3.9%, 1.8% and 3.3% in 2004, 2005 and 2006, respectively.

See “Item 10. Additional Information” for a description of the rights of securities holders, which remain unchanged.

We completed our initial public offering of 34,788,252 ordinary shares, in the form of ADSs, at US$10 per ADS in November 2005, after our ordinary shares and American Depositary Receipts were registered under the Securities Act. The aggregate price of the offering amount registered and sold was US$86,970,630, of which we received US$62,775,000. The effective date of our registration statement on Form F-1 (File number: 333-12917) was November 14, 2005. Morgan Stanley was the global coordinator and book runner for the global offering of our ADSs.

We received net proceeds of US$59.1 million from our initial public offering, which are expected to be used for general corporate purposes, including funding our working capital needs.

ITEM 15. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer have performed an evaluation of our disclosure controls and procedures, as that term is defined in Rules 13a-15(e) and 15a-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based on their evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2006, our disclosure controls and procedures were not effective due to the material weaknesses in our internal control over financial reporting described below. In light of such material weaknesses, we have implemented certain remedial measures to ensure that such issues will not be repeated. We believe that despite such weaknesses, the consolidated financial statements included in Item 18 comply with U.S. GAAP.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Under the supervision of the audit committee, our management has conducted an evaluation of our internal control over financial reporting as of December 31, 2006 based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our internal control over financial reporting includes those processes and procedures that (i) pertain to the maintenance of records that accurately and fairly reflect the transactions and dispositions of assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of assets that could have a material effect on the financial statements.

A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the financial statements will not be prevented or detected. The following material weaknesses have been identified and included in management’s assessment as of December 31, 2006:

The Company did not maintain effective controls over the financial reporting process due to an insufficient complement of personnel with a level of accounting knowledge, experience and training in the application of generally accepted accounting principles commensurate with the Company’s financial reporting. This material weakness contributed to the following control deficiencies, each of which is considered to be a material weakness:

(a). The Company did not maintain effective controls over the completeness and accuracy of the Company’s income tax balance sheet accounts and its related provision for income taxes. Specifically, the Company did not maintain effective controls over the uncertain tax positions and related analysis and accounting treatments. This control deficiency resulted in subsequent revisions and late adjustments to our income tax expense and related income tax balance sheet accounts in the 2006 annual consolidated financial statements.

(b) The Company did not maintain effective controls over its process to ensure the completeness and accuracy of the inventory balance. Specifically, the Company did not have effective controls over the process for estimating our provision for obsolete and excess inventory. This control deficiency resulted in subsequent revisions and late adjustments in our inventory provision at December 31, 2006.

These control deficiencies resulted in revisions in our financial statements and the delay in the finalization of our financial statements for the year ended December 31, 2006. In addition, these control deficiencies could result in a more than a remote likelihood that inaccurate accounts or disclosures, which may constitute a material misstatement of the consolidated financial statements, could occur. Accordingly, our management has determined that these control deficiencies constitute material weaknesses. Due to the existence of such material weaknesses, the Company did not maintain effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control – Integrated Framework issued by the COSO.

97

This annual report does not include a report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to audit by the Company’s registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit the Company to provide only management’s report in this annual report.

Remediation of Material Weaknesses

Our management has determined that these material weaknesses above were mainly caused by higher-than-expected attrition of personnel with U.S. GAAP reporting experience during the financial reporting season. Since such issue was identified, we have implemented, and will continue to implement, remedial measures to address this issue and to improve our internal control over financial reporting. Our audit committee has been actively involved during the preparation of our annual financial report, and, in 2007, we have hired a number of qualified personnel with accounting and financial reporting experience who are familiar with U.S. GAAP related matters, including income tax and inventory valuation. We will closely monitor the attrition of our accounting personnel and will maintain adequate human resources in financial reporting in the future. In addition, the Company is continuing to provide training programs related to SEC reporting and U.S. GAAP to our accounting and financial reporting personnel.

Changes in Internal Control

In our 2005 annual report on Form 20-F, we reported material weaknesses in our internal control over financial reporting in relation to (i) a lack of personnel with U.S. GAAP reporting experience, and (ii) the use of manual accounting systems that did not enable timely recording of transactions. In our attempt to remediate these previously reported material weaknesses and to enhance our overall control environment and corporate governance, we have undertaken significant efforts to strengthen our internal control over financial reporting and have implemented the following measures:

• We have established an internal audit department consisting of a director, who reports directly to our audit committee.

• Using the COSO framework as a guideline, we have designed and implemented internal control processes and procedures to improve our internal control over financial reporting. Such newly created processes and procedures have facilitated communications among our different departments and enabled us to formalize our control and procedures for financial reporting.

• We have provided training to our key employees regarding internal control processes and procedures and our Code of Business Conduct and Ethics.

• We officially launched our ERP system in January 2006, which allowed us to record transactions in a more timely and accurate manner.

Except for the remedial measures described above, there have been no significant changes in our internal control over financial reporting during the year ended December 31, 2006 that have materially affected, or a reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders

        of Vimicro International Corporation:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations and comprehensive income (loss), cash flows and shareholders’ equity present fairly, in all material respects, the financial position of Vimicro International Corporation (the “Company”) and its subsidiaries at December 31, 2006 and December 31, 2005, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2006 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 2(r) to the consolidated financial statements, effective January 1, 2006, the Company changed its method of accounting for share-based compensation in accordance with Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment”.

(Amounts expressed in U.S. dollars unless otherwise stated)

1. ORGANIZATION AND PRINCIPAL ACTIVITIES

Vimicro International Corporation (the “Company”) was incorporated under the laws of the Cayman Islands on February 24, 2004 as an exempted company with limited liability. It holds 100% of the equity interest of Vimicro Corporation (“Vimicro China”) which was established on October 14, 1999 in the People’s Republic of China (the “PRC”) as a limited liability company with an approved operating period of thirty years. The company also holds 100% of the equity interest of Vimicro Technology Corporation (“Vimicro Technology”) which was incorporated in Shenzhen, PRC in November 2006 to facilitate domestic sales and perform research and development. It has an approved operating period of twenty years. There were no activities in Vimicro Technology in 2006.

Vimicro China has two wholly-owned subsidiaries, Viewtel Corporation (“Viewtel”) and Vimicro Electronics International Limited (“Vimicro Electronics”). Viewtel was incorporated in California, United States of America in June 1999 to perform in-house research and development work. Vimicro Electronics was established in Hong Kong in May 2002 to facilitate international sales.

The Company, Vimicro China, Viewtel, Vimicro Electronics and Vimicro Technology, are hereinafter collectively referred to as the “Group”.

In December 2002, Vimicro China formed a company named Shanghai Pudong Micro-electronics Development Corporation (“SPMC”), with two other investors, Silicon Rain Technology (incorporated in the United States of America) and Shanghai Pudong Software Park (incorporated in the PRC) in Shanghai, to develop analog integrated circuit (“IC”) products. Although the Group owned only 32.5% equity interest in SPMC, it had an exclusive distribution right to all products developed by SPMC and was able to purchase them at cost and shared 40% of the gross profit derived from the sale of these products with SPMC. The Group had evaluated its relationship with SPMC in 2004 based on its investment and contractual relationships and considered SPMC its variable interest entity, while itself a primary beneficiary. The Group consolidated the financial position and operating results of SPMC from January 1, 2003 until December 23, 2004 when the Group disposed of its equity interest in SPMC and terminated the exclusive distribution arrangement. The net asset value of SPMC was approximately $229,000 as of December 23, 2004. SPMC incurred a net loss of approximately $1,348,000 for the period from January 1 to December 23, 2004. The net loss of SPMC attributable to the Company was approximately $438,000 for the period from January 1 to December 23, 2004.

The Group designs, develops and markets semiconductor products with multimedia applications, including personal computer (“PC”) camera multimedia processors and mobile phone multimedia processors. It is also involved in the packaging, testing and reselling of third party image sensors according to the Company’s specifications. Product manufacturing, certain product packaging and testing are outsourced to third party vendors.

1. ORGANIZATION AND PRINCIPAL ACTIVITIES (CONT’D)

Reorganization

The Company was established on February 24, 2004 with an authorized share capital consisting of 500,000,000 ordinary shares of $0.0001 each. Pursuant to the Reorganization, the authorized share capital of 500,000,000 ordinary shares at par value of $0.0001 each were subdivided into 484,352,868 ordinary shares and 15,647,132 preferred shares at par value of $0.0001 each. Each former owner of Vimicro China, or their nominees, subscribed for the shares of the Company in accordance with a shareholding transfer agreement between Vimicro China and the Company dated March 17, 2004. The form of shareholding transfer, either through an exchange of their equity interests in Vimicro China for proportional number of shares in the Company or by paying cash as consideration, depends on the nationality or places of incorporation of the former owners of Vimicro China.

All the former owners of Vimicro China obtained requisite approvals from the local governmental authorities and transferred their equity interests in Vimicro China to the Company on May 17, 2004.

In consideration for the shares transferred by each former owner of Vimicro China who was not a PRC entity or resident (each, a “non-PRC shareholder”), on October 13, 2004, the Company issued a total of 14,437,500 fully paid ordinary shares, representing 17.58% of its total outstanding share capital after the Reorganization, to these non-PRC shareholders or their designated nominees, based on these non-PRC shareholders’ pro rata interests (in total of 17.58%) in Vimicro China prior to the Reorganization.

In order to complete the Reorganization, the Company was required by the relevant PRC laws and regulations to pay cash to acquire the equity interest of Vimicro China from each former owner of Vimicro China who was a PRC entity or resident (each, a “PRC shareholder”). Shortly after the completion of its issuance and sale of preferred shares on October 12, 2004, the Company had applied part of its preferred shares issuance proceeds as payment to the PRC shareholders, amounting to US$8.4 million, for their 82.42% equity interest in Vimicro China. On November 19, 2004, these PRC shareholders and/or their respective nominees used the same amount of cash to subscribe for a total of 67,709,940 fully paid ordinary shares, which represents 82.42% of total outstanding share capital, of the Company after the Reorganization.

In summary, the Company issued 82,147,440 ordinary shares to the owners and/or their nominees of Vimicro China in exchange for their respective ownership interests in Vimicro China (collectively referred to as the “recapitalization transactions”). Since the recapitalization transactions were carried out to satisfy all the legal requirements on the Reorganization, the Company considers the Reorganization had been effectively completed for accounting purpose when it obtained all the requisite governmental authorities’ approvals on May 17, 2004.

VIMICRO INTERNATIONAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts expressed in U.S. dollars unless otherwise stated)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a) Basis of presentation

The Reorganization described in Note 1 was treated as capital stock reorganization and Vimicro China is considered as the predecessor of the Company. The consolidated financial statements are presented as if the Company was in existence for all periods presented.

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

(b) Principles of consolidation

The consolidated financial statements of the Group include the financial statements of the Company, its wholly-owned subsidiaries for all years presented and its variable interest entity, SPMC from January 1, 2004 to December 23, 2004.

Subsidiaries are those entities in which the Company, directly or indirectly, controls more than one half of the voting power; has the power to govern the financial and operating policies; to appoint or remove the majority of the members of the board of directors; or to cast majority of votes at the meeting of directors.

A consolidated variable interest entity is a variable interest entity of which the Company is the primary beneficiary.

All significant inter-company transactions and balances, and any unrealized gains arising from inter-company transactions, are eliminated in consolidation. Unrecognized gains arising from transactions with the associated company are eliminated to the extent of the Group’s interest in the associated company, against the investment in the associated company. Unrecognized losses are eliminated similarly but only to the extent that there is no evidence of impairment of the asset transferred.

(c) Associated company

An associated company is an entity in which the Group holds between 20% and 50% of the equity interest, or over which the Group has significant influence but does not control. Investment in associated companies is accounted for using the equity method. Equity accounting involves recognizing in the consolidated statement of operations the Group’s share of the profit or loss for the year of the associated company.

(Amounts expressed in U.S. dollars unless otherwise stated)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT’D)

(d) Use of estimates

The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Significant accounting estimates reflected in the Group’s consolidated financial statements mainly include useful lives of property, equipment and software, realization of deferred tax assets, provision for doubtful accounts, write-down of inventories and share-based compensation expenses.

(e) Risks and uncertainties and concentration of credit risk

The Group’s operating results are significantly dependent on its ability to develop and market products. The Group faces rapid technology development which requires the Group to continually improve the performance, feature and reliability of its products. Inability of the Group to successfully develop and market its products as a result of competition or other factors would have a material adverse affect on the Group’s business, financial condition and results of operations.

The Group depends on a few key customers for the majority of its sales, and the loss of or a significant reduction in orders from any of these customers would have a material adverse impact on its operating results. For the years ended December 31, 2004, 2005 and 2006, the top ten customers accounted for approximately 89%, 76% and 76% of total product revenue respectively. The Group cannot assure that these customers will continue to purchase products from them.

The following table summarizes the customers who accounted for more than 10% of the total revenue for the years ended December 31, 2004, 2005 or 2006:

	Years ended December 31
	2004	2005	2006
Customer A	31%	22%	5%
Customer B	29%	25%	28%
Customer J	—	4%	11%

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT’D)

(e) Risks and uncertainties and concentration of credit risk (cont’d)

The following table summarizes the customers who accounted for more than 10% of the total accounts receivables as of December 31, 2005 or 2006:

	As of December 31
	2005	2006
Customer A	10%	3%
Customer E	18%	4%
Customer I	13%	4%
Customer K	7%	18%
Customer O	8%	21%
Customer P	—	14%
Customer Q	—	16%

The Group relies on a few foundries for wafers and several companies for assembly and testing services for the existing products. The ability of each foundry to provide wafers is limited by the foundry’s available capacity. Moreover, the price of wafers may fluctuate based on the available industry capacity. The Group does not have long-term supply contracts with any of these foundries or assembly and testing houses. Therefore, the Group cannot be certain that these foundries and assembly and testing houses will allocate sufficient capacity to satisfy its requirements. If the Group is not able to obtain the necessary foundry capacity and assembly and testing capacity to produce the required volume for its customers in a timely manner, both its relationships with the customers and operating results would be adversely impacted.

Financial instruments that are potentially subject to credit risk consist of cash and cash equivalents, restricted cash and accounts receivable. Deposits held with financial institutions were not protected by statutory or commercial insurance. The Group performs ongoing credit evaluations of its customers’ financial conditions and, generally, requires no collateral or third party guarantee.

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 PRC foreign exchange trading system market.

(f) Fair value of financial instruments

The carrying amounts of the Group’s receivables, payables and accrued liabilities approximated their fair values as of the balance sheet dates due to their short maturities and the interest rates currently available.

(Amounts expressed in U.S. dollars unless otherwise stated)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT’D)

(g) Cash and cash equivalents

Cash and cash equivalents represents cash on hand and deposits placed with banks or other financial institutions, which are repayable on demand and have original maturities of three months or less.

(h) Inventories

Inventories are stated at the lower of cost or market. The cost is computed on a weighted average basis. Adjustments are made to write down excess or obsolete inventories to their estimated realizable values.

(i) Property, equipment and software

Property, equipment and software are stated at cost less accumulated depreciation and impairment loss.

Property, equipment and software are depreciated at rates sufficient to write off their costs less impairment loss, if any, over their estimated useful lives on a straight line basis. The estimated useful lives and residual values are as follow:

	Estimated useful lives	Residual value
Equipment and office furniture	5 years	10%
Leasehold improvements	Shorter of the lease term or the estimated useful lives	—
Mask and tooling	2 years	—
Motor vehicles	5 years	10%
Software	3 to 5 years	0 to 10%

Expenditures for maintenance and repairs are expensed as incurred.

The gain or loss on the disposal of property, equipment and software is the difference between the net sales proceeds and the carrying amount of the relevant assets and is recognized in the consolidated statements of operations.

(j) Allowance for doubtful accounts

Provisions are made against accounts receivable to the extent collection is considered to be doubtful. Accounts receivable in the balance sheets are stated net of such provision, if any. The Group has recorded $20,000 and $51,000 as of December 31, 2005 and 2006, respectively of allowance for doubtful accounts.

(k) Impairment of long-lived assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstance indicate that the carrying amount of the asset may no longer be recoverable. The assessment of possible impairment is based on the Group’s ability to recover the carrying value of the asset or asset group from the expected future pre-tax cash flows, undiscounted and without interest charges, of the related operations. When these events occur, the Group measures and recognizes the impairment loss as the amount by which the carrying amount exceeds the sum of the estimated discounted future cash flows expected to result from the use of the assets and their eventual disposition.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT’D)

(l) Revenue recognition

The Group recognizes revenue from the sales of products on a gross basis when the earnings process has been completed, as evidenced by agreement with the customer, delivery of products and transfer of title have occurred, as well as fixed or determinable pricing and probable collectibility has been assured.

Volume-based sales rebates on selected products are given to certain customers when the customers have completed a specified cumulative level of sales transactions. The cost of such rebates are accrued in accordance with EITF 01-9 “Accounting for Consideration Given by a Vendor to a Customer (Including a Reseller of the Vendor’s Product)”, by reducing the underlying sales transactions that are instrumental to earning the rebates based on the estimated number of customers that will ultimately earn and claim the rebates.

Payments received from customers in advance of shipment are recorded as advances from customers.

(m) Research and development costs

Research and development costs are charged to expense as incurred.

(n) Research and development grants

Research and development grants received from PRC government agencies or private enterprises are recognized as deferred grants and offset against the corresponding research and development expenses as and when they are incurred for the research and development projects for which these grants are received.

(o) Advertising costs

Advertising costs are charged to expense as incurred. Advertising costs were approximately $113,000, $652,000 and $678,000 for the years ended December 31, 2004, 2005 and 2006, respectively.

(p) Income taxes

Current income taxes are provided on the basis of income for financial reporting purposes, adjusted for income and expense items which are not assessable or deductible for tax purposes, in accordance with the regulations of the relevant tax jurisdictions.

Deferred income taxes are provided for using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the carrying amounts of assets and liabilities and their respective tax bases, and for the expected future tax benefits from loss carry-forwards, if any. Deferred tax assets and liabilities are measured using the enacted tax rates expected in the years of recovery or reversal and the effect from a change in tax rates is recognized in the consolidated statements of operations in the period of enactment. A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered more likely than not that some portion of, or all of the deferred tax assets will not be realized.

(q) Foreign currency translation

The functional currencies of the Company and its subsidiaries and consolidated variable interest entity are their respective local currencies. Assets and liabilities denominated in foreign currencies are translated using exchange rates in effect at the balance sheet dates. Income and expense items are translated at the average exchange rates prevailing during the year. These exchanges differences are included in the consolidated statement of operations. The reporting currency of the Group is the United States Dollar (“USD”).

Those entities that use a different functional currency are translated into USD using the applicable exchange rates quoted by the Bank of China at balance sheet dates for assets and liabilities and average exchange rates are used for the statements of operations. Translation adjustments resulting from translation of these consolidated financial statements are reflected as foreign currency translation adjustment in other comprehensive income (losses) in the shareholders’ equity.

(r) Share-based compensation

The Company adopted SFAS 123R using the modified prospective transition approach from January 1, 2006, prior to which the Company accounted for share-based compensation arrangements with employees in accordance with the provisions of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”) and related interpretations thereof. Pursuant to SFAS 123R, the Company recognized share-based compensation over the requisite service periods for any share option and restricted share granted after December 31, 2005 based on the fair values of share option and restricted share on the dates of grant. The Company continues to account for share options that were granted prior to the initial public filing of the Company’s F-1 registration statement with the United States Securities and Exchange Commission (“SEC”) on October 24, 2005 that remained unvested at December 31, 2005 under APB 25. For share-based awards granted after the initial public filing but prior to January 1, 2006, the unvested compensation cost at the effective date of adoption of SFAS 123R is computed based on the grant date fair values of those awards. The Company does not receive any tax benefits or deductions from awards exercised.

The Company recognizes share-based compensation using the accelerated method for all share-based awards issued prior to January 1, 2006. The Company has elected to recognize share-based compensation after the date of adoption of SFAS 123R using the straight-line method for all share-based awards issued after January 1, 2006, which results in the recognition of less share-based compensation in the first several years during the vesting period compared to that which would have been recognized had the Company used the accelerated method. Forfeitures were estimated based on historical experience and are periodically reviewed.

The Company accounts for share awards issued to non-employees in accordance with the provisions of SFAS 123R and EITF Issue No. 96-18, Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services (“EITF 96-18”). Under SFAS 123R and EITF 96-18, the Company uses the Black-Scholes option pricing model method to measure the value of options granted to non-employees at each reporting date to determine the appropriate charge to share-based compensation.

(r) Share-based compensation (cont’d)

Prior to the Company’s initial public filing, the Company accounted for employee share-based compensation using the intrinsic value method prescribed by APB 25 and applied the disclosure provisions of SFAS 123, as amended by SFAS 148 as if the minimum value method had been applied.

For share-based awards granted from the period between the initial public filing to December 31, 2005, the Company accounted for employee share-based compensation using the intrinsic value method prescribed by APB 25 and applied the disclosure provisions of SFAS 123, as amended by SFAS 148 as if the fair value method had been applied. If the fair value method had been used, the Company’s net income and net income per share for the year ended December 31, 2005 would have been adjusted to the pro forma amounts below:

(s) Employee social security and welfare benefit plans

All Chinese employees of the Company’s PRC entities and the variable interest entity participate in employee social security plans, including pension, medical, housing and other welfare benefits, organized and administered by relevant government authorities. The premiums and welfare benefit contributions that are borne by these entities are calculated based on percentages of the total salary of employees, subject to certain ceilings and are paid to the respective labor and social welfare authorities. The PRC government is responsible for the welfare benefit for the retired employees. The Group has no obligation for post retirement or other welfare benefits beyond the annual contributions.

The welfare benefits expenses were approximately $550,000, $969,000 and $1,856,000 for the years ended December 31, 2004, 2005 and 2006, respectively.

(t) Profit appropriation

The PRC entities and variable interest entity of the Group are required to make appropriations to statutory reserve funds based on after-tax net income, after recouping prior years’ losses, determined in accordance with PRC GAAP.

Vimicro China is a wholly foreign-owned enterprise established in the PRC. In accordance with the “The Law of the People’s Republic of China on Enterprises Operated Exclusively with Foreign Capital”, Vimicro China should set aside at least 10% of its net profit, after recouping prior years’ losses, determined under PRC GAAP to a statutory reserve fund before distributions to investors. The appropriation of the net profit to the statutory reserve fund must be made annually until the accumulated reserve fund exceeds 50% of Vimicro China’s registered capital.

(t) Profit appropriation (cont’d)

During the year ended December 31, 2004, there was no profit appropriation to statutory reserve funds because both Vimicro China and the variable interest entity were in an accumulated deficit position as determined in accordance with PRC GAAP.

During the years ended December 31, 2005 and 2006, Vimicro China and the appropriated approximately $1,437,000 and $1,295,000 respectively to this statutory reserve fund, which is not available for distribution except in liquidation.

(u) Segment reporting

The Group follows SFAS No. 131 “Disclosures about Segment of an Enterprise and Related Information.” The Group operates and manages its business as a single segment.

(v) Comprehensive income (loss)

Comprehensive income is defined as the changes in equity of a business enterprise during a period from transactions and other events or circumstances from non-owner sources. Comprehensive income includes foreign currency translation adjustments arising from the consolidation of the Company’s foreign subsidiaries and variable interest entity.

(w) Income (loss) per share

The Group has computed net income per share under two methods, basic and diluted. Basic net income per share is computed by dividing net income by the weighted average number of ordinary shares outstanding for the period. Diluted net income per share is computed by dividing net income by the sum of the weighted average number of ordinary shares outstanding and potential ordinary shares when dilutive.

The following table sets forth the computation of basic and diluted net income attributable to ordinary shareholders per share:

* These potentially dilutive securities were not included in the calculation of dilutive income (loss) per share because of their antidilutive effect.

In accordance with SFAS No. 128, “Computation of Earnings Per Share” (“SFAS No. 128”) and EITF Issue 03-06, “Participating Securities and the Two-Class Method under FASB Statement No. 128”, basic income per share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period using the two-class method. Under the two-class method, net income is allocated between ordinary shares and participating securities based on their participating rights. The Company’s Series A Preferred Shares are participating securities and were included in the computation of basic income per share for the year ended December 31, 2005. For the year ended December 31, 2004, the Company incurred losses of $5,612,000 and it was determined that the preferred shareholders have no obligation to share in the losses of the Company and therefore the dilutive effect of the preferred shares was not included in the computation of basic loss per share.

Diluted income per share is calculated by dividing net income attributable to ordinary shareholders as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the period. Ordinary equivalent shares consist of the ordinary shares issuable upon the conversion of the convertible preferred shares (using the if-converted method) and ordinary shares issuable upon the exercise of outstanding share options (using the treasury stock method).

(x) Operating leases

Rental payments under operating leases are charged to expense based on a straight line method over the period of the leases.

(y) Recent accounting pronouncements

In September 2006, the FASB issued Statement of Financial Accounting Standards No.157, “Fair Value Measurements” (“SFAS 157”), which defines fair value, establishes guidelines for measuring fair value and expands disclosures regarding fair value measurements. SFAS 157 does not require any new fair value measurements but rather eliminates inconsistencies in guidance found in various prior accounting pronouncements. SFAS 157 will be effective for the Company starting January 1, 2008. Earlier adoption is permitted, provided the company has not yet issued financial statements, including for interim periods, for that fiscal year. The Company is currently evaluating the impact of SFAS 157 on its consolidated financial position, cash flows and results of operations.

In July 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement No. 109” (“FIN 48”), which clarifies the accounting for uncertainty in tax positions. This Interpretation requires that the Company recognize and disclose in its financial statements the impact of a tax position if that position is more likely than not of being sustained on tax audit, based on the technical merits of the position. The provisions of FIN 48 became effective for the Company on January 1, 2007, with the cumulative effect of the change in accounting principle, if any, recorded as an adjustment to opening retained earnings. The Company has evaluated the impact of FIN 48 and believes that it has no material impact on its consolidated financial position, cash flows and results of operations.

In June 2006, the FASB ratified the provisions of the Emerging Issue Task Force Issue No. 06-3 “How Sales Taxes Collected from Customers and Remitted to Governmental Authorities Should Be Presented in the Income Statement” (“EITF 06-3”), which requires the Company to disclose how it accounts for taxes imposed on and concurrent with a specific revenue-producing transaction. EITF 06-3 will be effective for the Company starting January 1, 2007. The Company does not believe that the application of EITF 06-03 will have a material effect on its financial position.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”). SFAS 159 permits companies and not-for-profit organizations to make a one-time election to carry eligible types of financial assets and liabilities at fair value, even if fair value measurement if not required under U.S. GAAP. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company does not believe that the adoption of SFAS 159 will have a significant impact on its financial position, result of operations or cash flows.

8. SHAREHOLDERS’ EQUITY

Ordinary Shares

Following the Reorganization (Note 1) on May 17, 2004, the Company has an authorized share capital of 500,000,000 Ordinary Shares of par value at $0.0001 each, which was subsequently subdivided into 484,352,868 Ordinary Shares and 15,647,132 Preferred Shares at par value of $0.0001 each. On the same day, the Company issued 82,147,440 Ordinary Shares to the former owners of Vimicro China in exchange for their interests in Vimicro China as described in Note 1. The share capital of the Company has been retroactively restated as if the Company’s Ordinary Shares were issued from the beginning of the earliest period presented. The additional paid-in capital on Ordinary Shares represents the difference between the share capital of the Company and the capital of Vimicro China.

In October 2005, certain share option holders exercised their options totaling 14,241,437 shares, among which 2,715,000 options were not vested. These early exercised shares had the following features:

The Company’s right to purchase

These shares were subject to the Company’s right to repurchase during the remaining vesting periods if the optionee’s employment with the Company is terminated for any reason during the vesting periods. If the Company exercises its right of repurchase, the price to be paid shall be the lower of the exercise price per share paid by the optionees to the Company pursuant to the option agreement or the fair value of the shares at the date of repurchase.

Restriction on Transfer

The optionee shall not transfer the shares acquired through early exercise of the unvested options during the vesting period.

Early exercised Ordinary Shares are excluded from basic EPS until the shares are vested and the Company’s right to repurchase these shares has lapsed. From the date of exercise to December 31, 2005, 745,000 shares out of 2,715,000 restricted Ordinary Shares became vested and treated as Ordinary Shares. During year 2006, 1,320,000 shares became vested and treated as Ordinary Shares.

On November 15, 2005, the Company completed its initial public offering of 8,697,063 American Depositary Shares (“ADS”), representing 34,788,252 ordinary shares, at US$10.00 per ADS (or US$2.50 per ordinary share). Of these, 6,750,000 ADSs, representing 27,000,000 ordinary shares, were sold to the public by the Company, and 1,947,063 ADSs, representing 7,788,252 ordinary shares, were sold to the public by the Company’s selling shareholders. After deducting commissions and other offering expenses, the Company received net proceeds of $59.1 million.

15,217,150 Preferred Shares were converted into an equal number of ordinary shares effective upon the completion of the Company’s initial public offering. (Refer to Note 9)

9. REDEEMABLE CONVERTIBLE PREFERRED SHARES

In October 2004, the Group issued an aggregate of 15,217,150 shares of redeemable convertible preferred shares (“Preferred Shares”) in a private placement at a price of $1.5977 per share to a group of institutional and private investors (collectively, the “Preferred Shareholders”). The preferred shareholders were entitled certain preference, such as liquidation, redemption and dividend preferences over Ordinary Shareholders. All preferred shares were converted automatically into equal number of ordinary shares in November 2005 upon the initial public offering of the ADS of the company.

As of December 31, 2005 and 2006, there were no preferred shares issued and outstanding.

10. SHARE-BASED COMPENSATION

The Company has three share option plans to honor the contributions of employees and non-employee consultants. The first plan is a discretionary share option plan adopted in March 2004 concurrent with the Reorganization of the Company. The second share option plan was adopted in March 2004 (the “2004 Plan”). The third plan was later adopted in November 2005 (the “2005 Plan”) to replace the 2004 Plan. Details of each plan and the respective share-based compensation are as follows:

No income tax benefit was recognized in the statements of operations for share-based compensation arrangements for the years ended December 31, 2004, 2005 and 2006 as no tax deduction was claimed.

The Company expects to issue new ordinary shares to satisfy share option exercises.

Discretionary share options:

Employee options:

Concurrent with the Reorganization of the Company, the Company’s shareholders approved the grant of share options to certain employees to honor the Company’s promises to issue share options upon the formalization of the share capital and option structures of the Company.

The Company did not record any employee share-based compensation prior to 2004 because the shareholders had not approved the grant of share options and Company’s legal capital structure as well as the legal environment in which the Company operated did not allow the employees to exercise the promised options.

In March 2004, the shareholders of the Company passed a resolution to grant a total of 17,574,448 discretionary share options to employees of Vimicro China at an exercise price ranging from $0.01 to $0.60 each, and a vesting period ranging from 0 to 5 years and an exercise period of 10 years from the date of grant. 6,690,898 of these discretionary share options were immediately vested to honor the previous promised provisionally issuable share options, with the remaining 10,883,550 options to be vested over a period of 1 to 5 years for future services. The fair value of the Company’s ordinary shares as of March 2004 of $1.14 per share and the intrinsic value ranging from $0.54 to $1.13 per share have been used to measure the compensation expenses. Prior to the adoption of FAS 123(R), the Company recognized compensation expenses under APB 25 of approximately $13,353,000, $1,440,000 for the years ended December 31, 2004 and 2005, respectively. After the adoption of FAS 123(R), the Company recognized compensation expenses of approximately $199,000 for the year ended December 31, 2006.

(Amounts expressed in U.S. dollars unless otherwise stated)

Non-employee options:

In March 2004, the shareholders of the Company passed a resolution to grant a total of 2,323,500 discretionary share options to non-employee consultants at an exercise price ranging from $0.01 to $0.60 each and a vesting period ranging from 0 to 5 years and an exercise period of 10 years from the date of grant. 2,050,500 of these discretionary share options were immediately vested to honor the previous provisionally issued share options due to non-employee consultants for services previously rendered, with the remaining 273,000 options to be vested over a period ranging from 1 to 4 years for future services. The Company recorded consultancy fees with respect to research and development activities of approximately $413,000, $145,000 and $155,000 for the years ended December 31, 2004, 2005 and 2006 respectively.

2004 Share Option Plan:

In March 2004, the shareholders of the Company passed a resolution to adopt a 2004 Share Option Plan (the “2004 Plan”) that provides for the granting of share options to employees and non-employee consultants of the Company. The Company has reserved 12,541,080 Ordinary Shares for grant under the 2004 Plan.

Options granted under the 2004 Plan have a vesting period of 5 years. The vesting schedule is as follows:

• 20% of the share options will vest 1 year after the grant date, and subsequently,

• 10% of the share options shall vest semi-annually over the next 4 years, or 1/60 of the shares options shall vest monthly over the next 4 years.

Each granted option has a term of 10 years from the date of grant. The Board of Directors may terminate the Plan at any time at its discretion.

The 2004 Plan was terminated in November 2005, and the remaining options available for grant were transferred to the 2005 Share Option Plan.

Employee options:

Under the 2004 Plan, the Company granted share options to employees as summarized below:

Date of grant	Number of shares	Exercise price
2004-10-14	7,305,400	1.60
2005-01-31	178,700	1.80
2005-05-02	497,000	2.10
2005-08-12	1,045,100	3.00
2005-10-28	980,400	2.50

Prior to the adoption of FAS 123(R), the Company did not recognize compensation expenses in connection with these options granted because the exercise price of these options was greater than the estimated fair value of the underlying Ordinary Shares as of each grant date. After the adoption of FAS 123(R), the Company recognized compensation expenses of approximately $449,000 for the year ended December 31, 2006, related to the 980,400 option granted on October 28, 2005 which was valued using the fair-valued

method. For the other options which were valued using the minimum value method, following the transition provision of FAS123R, the Company continued to account for the portion of awards outstanding using APB25, which was the accounting principle originally applied.

Non-employee options:

Under the 2004 Plan, for the service of non-employee consultants, the Company granted share options to non-employees as summarized below:

Date of grant	Number of shares	Exercise price
2004-10-14	286,800	1.60
2005-01-31	60,000	1.80
2005-05-02	160,000	2.10
2005-10-28	158,000	2.50

The Company estimated that the fair values of the consultancy services provided approximate the estimated fair values of the share options granted to the consultants. The Company recorded consultancy fee expense with respect to research and development activities of approximately $15,000, $126,000 and $294,000 for the years ended December 31, 2004, 2005 and 2006 respectively.

2005 Share Option Plan:

Employee options:

In November 2005, the shareholders of the Company passed a resolution to adopt a 2005 Share Option Plan (the “2005 Plan”) to replace the 2004 Plan that provides for the granting of share options to employees and non-employee consultants of the Company. All 3,065,505 share options, which were not issued under the 2004 option Plan were transferred to the 2005 Plan. Subsequently, another 10,000,000 shares were authorized for future grant. Option grants thereafter shall be made under the new 2005 Plan and no new options shall be granted under the 2004 Plan. The Company has reserved 13,065,505 Ordinary Shares for grant under the 2005 Plan. On December 14, 2006, another 8,000,000 share options was authorized for grants in year of 2007.

Options granted under the 2005 Plan have a vesting period of 5 years. The vesting schedule is as follows:

• 20% of the share options will vest 1 year after the grant date, and subsequently,

• 10% of the share options shall vest semi-annually over the next 4 years.

Each granted option has a term of 10 years from the date of grant. The Board of Directors may terminate the 2005 Plan at any time at its discretion.

by the same holding company. Vimicro Electronics makes royalty payments to Vimicro China for certain technologies licensed from Vimicro China. Accordingly, Vimicro China is subject to a 5.25% withholding tax on royalties received from Vimicro Electronics, which Vimicro Electronics withholds and pays over to the tax authorities in Hong Kong on behalf of Vimicro China. Upon approval by the relevant PRC tax authorities, the amount of withholding tax paid on royalty income to Hong Kong tax authority can be treated as a foreign tax credit by Vimicro China. Thus, it can be used to offset the tax payable on the same source of income for PRC tax purpose.

In connection with the offshore position filed by Vimicro Electronics in 2006, the Company assessed and concluded it is more likely than not that Vimicro Electronics would satisfy the requirements of obtaining offshore status and would not be subject to Hong Kong withholding tax on royalty income. Accordingly, the Vimicro Electronics recorded a withholding tax refundable of approximately $982,000 as of December 31, 2006. In addition, Vimicro Electronics reversed all tax account balances related to the onshore filing positions and recognized a tax benefit of approximately $201,000 for the year ended December 31, 2006, as a result of changes in its filing position.

After the value-added tax is levied, Vimicro China is, subject to government approval, entitled to a refund for the portion exceeding 3% of the actual VAT collected by Vimicro China for sales to customers in China.

According to the latest IC VAT refund policy from the relevant tax authorities in September 2004, the above VAT refund benefit was no longer available beginning from April 1, 2005.

For the years ended December 31, 2004, 2005 and 2006, tax refunds amounting to approximately $110,000, nil and nil, respectively, were recorded as other income after obtaining the required approval from the relevant tax authorities.

The aggregate consideration for the acquisition of the land-use rights and the construction of the new building is estimated to be approximately US$38.3 million. The proposed project, including the gross land area and construction site area, is subject to governmental approval. Should the governmental authorities request us to modify the project, the land and construction site areas, as well as the total cost for the project, may change. It is estimated that the construction of this new building will be completed by 2009.

16. SUBSEQUENT EVENTS

(a) Change in tax law

On March 16, 2007, the National People’s Congress adopted the New Income Tax Law, which will become effective as of January 1, 2008 and will replace the existing separate income tax laws for domestic enterprises and foreign-invested enterprises. According to the New Income Tax Law, the new enterprise income tax rates for the domestic and foreign enterprise are unified at 25% income tax rate, effective January 1, 2008. However, there will be a five-year transition period for foreign-invested enterprises. Since Vimicro currently enjoys the three-year preferential treatment of 10% income tax rate as a “ Advanced Technology Enterprise with Foreign Investment” from 2006 to 2008, Vimicro China will still be subject to the 10% income tax rate in 2008 in accordance with the New Income Tax Law. In addition, under the New Income Tax Law, a “resident enterprise,” which includes an enterprise established outside of China with management located in China, will be subject to PRC income tax.

If the PRC tax authorities subsequently determine that we should be deemed a resident enterprise, then our global income will be subject to PRC income tax at a tax rate of 25%. Under the New Income Tax Law, certain qualified “high and new technology companies” may be entitled to a 15% preferential tax rate. However, as the detailed implementation regulation of the New Income Tax Law has not yet been issued, it is unclear whether Vimicro China can qualify as a “high and new technology company” after the New Income Tax Law becomes effective.

(b) Property acquisition

On June 27, 2007, we entered into an agreement with Shenzhen Municipal Bureau of Land Resources and Housing Management, pursuant to which, in consideration of approximately US$856,000, we acquired land use rights for approximately 3,947 square meters of land in Shenzhen High-Tech Industrial Park. The land will be the site of a new building, which will become Vimicro Technology’s office building and accommodate a research and development center. Governmental authorities would require us to obtain necessary governmental approvals for the proposed project. It is estimated that the construction of this new building will be completed by 2009.

(c) Option granted

During the first half year of 2007, the Company has granted 2,161,300 options to purchase ordinary shares to certain employees and 15,000 options to non-employees at exercise price from $1.28 to $2.54 per share. The Company also granted 982,000 restricted shares to certain employees.
