RISK FACTORS

          Investing in our ADSs involves a high degree of risk. You should carefully consider the risks described below together with the other information contained in this prospectus before making an investment decision. The trading price of our ADSs could decline due to any of these risks and you may lose all or part of your investment.

Risks Related to Our Business

Our limited operating history makes evaluating our business and prospects difficult.

          We commenced operations in July 2002 and completed our first design project in September 2003. As a result, we have a limited operating history, which may not provide a meaningful basis for evaluating our business and prospects. We may not have sufficient experience to address the risks frequently encountered by early stage companies, including our potential inability to:

	•	manage our growth effectively;
	•	maintain our profitability or margin;
	•	acquire and retain customers;
	•	attract, train and retain qualified personnel;
	•	maintain adequate control of our costs and expenses;
	•	keep up with evolving industry standards and market developments; or
	•	respond to competitive market conditions.

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

If we fail to effectively manage our growth and transition into a public company, our business may be adversely affected.

          We are a new company that has experienced rapid growth and expansion, which has strained, and continues to strain, our resources. Our staff increased from 311 as of December 31, 2003 to 890 as of December 31, 2004. We expect to expand our engineering team significantly in the near future in anticipation of the potential growth of our business. To accommodate our growth, we will need to implement a variety of new and upgraded operational and financial systems, procedures and controls, including improvements to our accounting and other internal management systems by dedicating additional resources to our reporting and accounting function, and improvements to our record keeping and contract tracking system. Further, as we become a public company, we will need to augment our support infrastructure because our information and control systems must enable us to prepare accurate and timely financial information and other required disclosure.

          All of these measures will require substantial management efforts. We cannot assure you that we will be able to implement the measures successfully or to effectively manage our growth and transition into a public company; any failure to do so may adversely and materially affect our business.

If mobile handset brand owners discontinue or reduce the use of independent mobile handset design houses, our business will be materially and adversely affected.

          The growth of our independent mobile handset design business depends substantially on the extent to which mobile handset brand owners outsource the mobile handset design function to independent mobile handset design houses like us, as opposed to designing mobile handsets themselves or through other third parties such as ODMs and EMS providers. Currently, some leading international mobile handset brand owners still design most of their mobile handsets in-house. If mobile handset brand owners discontinue or

If we fail to retain existing or attract additional international mobile handset brand owners as customers, our business will be materially affected and the growth of our business impaired.

          As international mobile handset brand owners offer high growth potential to our business, we believe that our future growth and success will depend substantially on the extent to which leading international mobile handset brand owners engage us to design their mobile handsets. Although international mobile handset brand owners such as Alcatel, Kyocera, Mitsubishi and NEC have engaged us to design mobile handsets for them, we cannot assure you that any of them will continue to use us to design their new mobile handset models, nor can we assure you that we will be able to attract new international customers through our marketing efforts. If we fail to retain existing or attract additional international mobile handset brand owners as customers, our business would be materially affected and the growth of our business will be impaired.

If our customers fail to achieve success in their business, our mobile handset design business could be adversely affected.

          If any of our customers is unsuccessful in its mobile handset sales, whether due to lack of market acceptance of its products, shortage of component supplies, slowdown of replacement sales of mobile handsets or otherwise, the customer may downsize or discontinue its mobile handset business, which in turn could adversely affect our design business. Accordingly, our success depends on our customers’ success in their business. Chinese mobile handset brand owners have historically accounted for most of our revenues. We are not certain whether these Chinese mobile handset brand owners will be able to achieve success in their business and how long they will remain competitive in their business even if initially successful. For example, the Chinese mobile handset brand owners are reportedly experiencing declining profitability due to intense competition from international brand owners and decrease in consumer demand. This could cause some of our Chinese customers to cut back on new model introductions or exit the market.

Defects in our designs could result in a loss of customers and claims against us.

          Our mobile handset designs are complex and must meet stringent quality requirements. Complex designs such as mobile handset designs sometimes contain defects, errors and bugs when they are first introduced. If any of our designs 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 customers may be reluctant to continue to contract with us, which could harm our ability to retain existing customers and attract new customers. Because we cannot test for all possible scenarios, our designs may contain errors that are not discovered until mass production of mobile handsets. These problems may result in a loss of our customers as well as claims against us. For example, NEC once sought compensation from us due partly to defects in some third-party components we sourced and incorporated in a mobile handset model for NEC. NEC later acknowledged that the design defects were attributable to the third-party components and cancelled its claim against us in light of the new mobile handset models successfully designed by us. We cannot assure you that we will not be subject to new claims by NEC or other customers in the future, and if we fail on the merits of these claims, our business and results of operations could be materially and adversely affected.

We may experience earnings or margin declines or even net losses in the future.

          Although we have recorded net income since the end of 2002, we cannot assure you that we will sustain our level of profitability 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 revenues could materially and adversely affect our results of operations and result in substantial operating losses. In addition, competition from other independent mobile handset design houses and ODMs may force us to reduce our prices to maintain our competitive position. If we do not sustain or increase profitability or otherwise meet the expectations of securities analysts and investors, the market price of our ADSs will likely decline.

If we cannot keep up with industry standards and design new mobile handset models in a timely and cost-efficient manner to meet our customers’ demand, the growth and success of our business will be materially and adversely affected.

          The mobile handset market is characterized by changing end user preferences and demand for new and advanced functions and applications on mobile handsets, rapid product obsolescence and price erosion, intense competition, evolving industry standards and wide fluctuations in product supply and demand. If we cannot design new mobile handset models in a timely and cost-efficient manner to meet our customers’ demand, the growth and success of our business will be materially and adversely affected.

          To date, we have derived most of our net revenues from the design and development of 2.5G mobile handsets based on the GSM/ GPRS technology. As the market for 2.75G and 3G mobile handsets develops, our existing and potential customers may increasingly demand 2.75G and 3G mobile handset designs. We have only recently begun to design 2.75G and 3G mobile handsets, and we do not have a proven track record in this market. We cannot assure you that our existing and potential customers will engage us to design 2.75G and 3G mobile handsets for them. Even if we receive orders for 2.75G and 3G mobile handset designs, we cannot assure you that we will be able to successfully meet our customers’ demand with respect to cost, quality and time to completion. Our failure to meet customer demand could hurt our reputation and affect our business and results of operation.

We rely on a limited number of customers for a significant portion of our net revenues, and if a large customer fails to place additional orders with us, or if we fail to attract additional major customers, our results of operations and financial condition could be materially and adversely affected.

          We have been dependent on a small number of customers to generate a significant portion of our net revenues. In 2003, our top three customers collectively accounted for approximately 88.2% of our net revenues, and each of Beijing Sunrise, Lenovo and NEC contributed more than 10% of our net revenues. In 2004, our top four customers collectively accounted for approximately 56.8% of our net revenues, and each of Lenovo and NEC contributed more than 10% of our net revenues. We do not have long-term contracts with any of our customers. Sales to our largest customers have varied from period to period due primarily to our relatively short period of operation and the relatively fast expansion of our customer base. Our largest customers are expected to vary significantly in the future as we aim to attract more international mobile handset brand owners as our customers.

          We expect that we will continue to rely on a small number of customers for a significant portion of our revenues in the foreseeable future. Our ability to maintain close relationships with these customers is essential to the growth and profitability of our business. If a major customer fails to place additional orders with us, or if we fail to develop additional major customers, our revenues could decline, and our results of operations and financial condition could be materially and adversely affected.

The mobile handset design market in China is highly competitive, and we cannot assure you that we will be able to compete successfully against our competitors.

          The mobile handset design market in China is intensely competitive and highly fragmented. We face competition from other independent mobile handset design houses in China, including Cellon, Shenzhen Jingwei, Shanghai Yiren and Shanghai Yuhua. We also face competition from independent mobile handset design houses based in other countries, to the extent we try to enter the markets that they are serving or they try to enter the mobile handset design market in China. In addition, we face current and potential future competition from established suppliers of wireless communications solutions to mobile device manufacturers, which may be in a position to design mobile handsets on their own. These suppliers include ODMs such as BenQ, Compal Communications and Arima Communications. Further, partly due to the low entry barriers to our business, an increasing number of new players may enter the independent mobile handset design market in the near future. These new players may include independent mobile handset design houses that used to be affiliated with traditional mobile handset brand owners.

          Many of our current and potential competitors have significantly greater financial, technical, 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.

If we lose our license for CDMA technology, we may not be able to obtain alternative licenses in a timely manner.

          We are dependent on QUALCOMM for CDMA-related technology we use in designing CDMA-based mobile handsets. Suspension or termination of our CDMA license agreement by QUALCOMM could adversely affect our business and prospects, because we may not be able to obtain alternative licenses in a timely manner to meet our customers’ demands.

We are subject to risks from customers’ claims for refund and liquidated damages.

          Our agreements with many customers contain refund and liquidated damages provisions, which entitle the customer to demand a refund and liquidated damages if we cannot complete a mobile handset design by the deadline or if the requisite certifications cannot be obtained. We cannot assure you that we will be able to successfully perform every customer contract, or that costs associated with refunds and liquidated damages will not be material.

We have not registered copyrights for our product designs and other intellectual property.

          We have not registered copyrights in China for any of our inventions, original works of authorship, developments and improvements relating to mobile handset designs. Under applicable PRC law, owners of copyrights may choose not to register copyrights and the non-registration does not constitute abandonment or deletion of the copyrights. However, under PRC law, if a third party infringes on our unregistered copyrights, we bear the burden of proving that we are the legitimate owner of these copyrights. We cannot assure you that we will prevail on our ownership claims if we encounter any infringements of our designs.

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, trademark and trade secret laws, as well as nondisclosure agreements and other methods to 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. Although we are not currently involved in any litigation, we may need to resort to court action to enforce our intellectual property rights. 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 adversely affect us.”

We may face intellectual property infringement and other claims that could be time-consuming and costly to defend and result in our loss of significant rights.

          Other parties may assert intellectual property infringement and other claims against us. Litigation is expensive and time-consuming and could divert management’s attention from our business. If there is a successful claim of infringement, 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. Parties asserting infringement claims may be

          In addition, our competitors may initiate litigation proceedings against us or our employees that may strain our resources, divert our management attention or damage our reputation. For example, Cellon brought an unfair competition proceeding against our former affiliate, Beijing Qidi, and 18 of its employees who subsequently joined us in connection with our divestment from Beijing Qidi. We settled the litigation on behalf of Beijing Qidi and these 18 individuals in order to facilitate our divestment and the transfer of these employees to our company. See “Business — Legal Proceedings” for more details. We cannot assure you that similar proceedings will not occur in the future.

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

          Our future success depends heavily upon the continued services of our senior executives, especially our Chief Executive Officer, Mr. Defu Dong. We rely on their experience in mobile handset design, business operations and selling and marketing and on their relationships with our shareholders and customers. We do not maintain key-man life insurance for any of our key executives. If one or more of our key executives are unable or unwilling to continue in their present positions, we may not be able to replace them easily or at all. Therefore, our business may be severely disrupted, and we may incur additional expenses to recruit and retain new officers.

          Several executives of our company, including our Chairman and Chief Executive Officer, Mr. Defu Dong, were involved in litigation, arbitration or administrative proceedings in the past. See “Business — Legal Proceedings.” Although we are not aware of any pending claims against us or our executives, any future litigation or administrative proceedings involving any of our key executives may result in diversion of management attention to our business, or damage to our reputation. In addition, if any of our executives joins a competitor or forms a competing company, we may lose our customers. Each of our executive officers has entered into an employment agreement with us, which contains confidentiality and non-competition provisions. If any disputes arise 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 and hold most of their assets, in light of the uncertainties with PRC legal system. See “— Risks Related to Doing Business in China — Uncertainties with respect to the PRC legal system could adversely affect us.”

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

          Our future success depends on our ability to attract, train and retain additional skilled engineers. Our industry is characterized by high demand and intense competition for talent. We have experienced an approximately 20% annual attrition rate to date. We cannot assure you that we will be able to retain existing or attract and retain new skilled engineers whom we will need to achieve our strategic objectives. In addition, as we are still a 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.

We experience fluctuations in quarterly operating results.

          Our quarterly operating results have fluctuated in the past and will likely fluctuate in the future. These fluctuations in operating results depend on a variety of factors, including the demand for our design services, the amount of design fees and royalties our customers agree to pay us, the number of milestones we have achieved, the revenues recognized from completion of the design contracts with completion fees, the amount of time required for completion of design contracts, research and development expenses related to our preparation for the design of new mobile handset models, the rate of growth of leading international mobile phone brand owners’ outsourcing of the mobile phone design function, pricing pressure due to competition

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 or companies. Future acquisitions would expose us to potential risks, including risks associated with the assimilation of new technologies and personnel, unforeseen or hidden liabilities, the diversion of management attention and resources from our existing business and the inability to generate sufficient revenues 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.

We have limited business insurance coverage in China.

          The insurance industry in China is still at an early stage of development. Insurance companies in China offer limited business insurance products. As a result, we do not have any business liability or disruption insurance for our operations in China. Any business disruption, litigation or natural disaster may result in substantial costs and diversion of our resources.

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

          On December 16, 2004, the Financial Accounting Standards Board, or FASB, issued SFAS No. 123 (revised 2004), Share-Based Payment , which requires a public company to recognize, as an expense, the fair value of stock options and other share-based compensation to employees at the beginning of the first annual or interim period after June 15, 2005. We intend to adopt a 2005 share incentive plan that will allow us to grant options, restricted shares and other equity incentives to our employees. If such plan is adopted by our board of directors and approved by our shareholders, we could have significant compensation charges for the periods after June 15, 2005 for options, restricted shares and other share-based compensation granted under the plan, and our net income could be adversely affected.

Risks Related To Doing Business in China

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

          Substantially all of our business operations are conducted in China. We also believe that a significant portion of the mobile handsets we design are sold to end users in China. Accordingly, our results of operations, financial condition and prospects are subject to a significant degree to the economic, political and legal developments of China. Since the late 1970s, the Chinese government has been reforming the economic system in China. These reforms have resulted in significant economic growth. However, 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 Chinese 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 mobile handset industry. Such developments could materially and adversely affect our business, lead to reduction in demand for our services and materially and adversely affect our competitive position.

Our business benefits from certain tax incentives, and changes to these tax incentives could adversely affect our operating results.

          The Chinese government has provided various tax incentives to domestic high technology companies, including our Chinese subsidiaries, in order to encourage the development of technology companies. For example, as high technology companies operating in an approved technology development zone, our

Our subsidiaries in China are subject to restrictions on paying dividends to us, making other payments to us or any other affiliated company and borrowing or allocating tax losses among our subsidiaries.

          We are a holding company incorporated in the Cayman Islands. We conduct substantially all of our operations through our four subsidiaries in China. Current PRC regulations permit our subsidiaries in China to pay dividends to us only out of their respective accumulated profits, if any, determined in accordance with PRC accounting standards and regulations. In addition, our subsidiaries in China are each required to set aside at least 10% of their respective accumulated profits each year, if any, to fund certain reserve funds. These reserves are not distributable as cash dividends. In addition, current PRC regulations prohibit inter-company borrowings or allocation of tax losses among our subsidiaries in China. Further, if any of our subsidiaries 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 payments to us.

Fluctuations in exchange rates could result in foreign currency exchange losses.

          All of our sales proceeds are denominated in RMB, while a small portion of our cost of revenues is denominated in U.S. dollars. Fluctuations in exchange rates, primarily those involving the U.S. dollar, may affect our cost of revenues and profit margins as well as our net income. In addition, these fluctuations could result in exchange losses and increased costs in RMB terms. Furthermore, as we rely entirely on dividends paid to us by our subsidiaries in China, any significant revaluation of the RMB may have a material adverse effect on the value of, and any dividends payable on our ADSs in foreign currency terms. If we decide to convert RMB we receive from our subsidiaries into U.S. dollars for the purpose of distributing dividends on our ordinary shares or for other purposes, appreciation of the U.S. dollar against the RMB would have a negative effect on the U.S. dollar amount available to us. Very limited hedging transactions are available in China to reduce our exposure to exchange rate fluctuations. To date, we have not entered into any hedging transactions to reduce our exposure to foreign currency exchange risk. In addition, our currency exchange losses may be magnified by China’s exchange control regulations that restrict our ability to convert RMB into U.S. dollars.

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

          Because most of our net revenues are denominated in RMB, any restrictions on currency exchange may limit our ability to use revenues generated in RMB to fund any business activities we may have outside China or to make dividend payments in U.S. dollars. The principal regulation governing foreign currency exchange in China is the Foreign Currency Administration Rules (1996), as amended. Under these rules, RMB are freely convertible for trade and service-related foreign exchange transactions, but not for direct investment, loan or investment in securities outside China unless the prior approval of the State Administration of Foreign Exchange is obtained. Although the PRC government regulations now allow greater convertibility of RMB for current account transactions, significant restrictions still remain. For example, foreign exchange transactions under our subsidiaries’ capital account, including principal payments in respect of foreign currency-denominated obligations, remain subject to significant foreign exchange controls and the approval of the State Administration of Foreign Exchange. These limitations could affect our ability to obtain foreign exchange for capital expenditures. We cannot be certain that the PRC regulatory authorities will not

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

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

Any prolonged recurrence of SARS or other adverse public health developments in China may have a material adverse effect on our business operations, financial condition and results of operations.

          In the first half of 2003, China and certain other countries experienced an outbreak of a new and highly contagious form of atypical pneumonia known as SARS. The SARS outbreak damaged the economy of China as a whole. On July 5, 2003, the World Health Organization declared that SARS had been contained. Any recurrence of SARS or other adverse public health developments in China may have an 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. We have not adopted any written preventive measures or contingency plans to combat any future outbreak of SARS or any other epidemic.

Risks Related to this Offering

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

          Prior to this initial public offering, there has been no public market for our ordinary shares or ADSs. We have applied for our ADSs to be quoted on the Nasdaq National Market. Our ordinary shares will not be listed on any exchange. If an active trading market for our ADSs does not develop after this offering, the market price and liquidity of our ADSs will be materially and adversely affected.

          The initial public offering price for our ADSs will be determined by negotiations between us and the underwriters and may bear no relationship to the market price for our ADSs after the initial public offering. We cannot assure you that an active trading market for our ADSs will develop or that the market price of our ADSs will not decline below the initial public offering price.

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;
	•	changes in financial estimates by securities research analysts;
	•	conditions in the mobile handset market;
	•	changes in the economic performance or market valuations of other mobile handset design houses;
	•	performance of other China-based companies that are quoted on Nasdaq;
	•	announcements by us or our competitors of new products, acquisitions, strategic partnerships, joint ventures or capital commitments;

13

Table of Contents

	•	addition or departure of key personnel;
	•	fluctuations of exchange rates between RMB and U.S. dollar;
	•	litigation related to our intellectual property or key employees; and
	•	release of lock-up or other transfer restrictions on our outstanding ADSs or sales of additional 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 materially and adversely affect the market price of our ADSs.

You will experience immediate and substantial dilution in the net tangible book value of ADSs purchased.

          The initial public offering price per ADSs will be substantially higher than the net tangible book value per ADS prior to the offering. Consequently, when you purchase ADSs in the offering at the initial public offering price, you will therefore incur an immediate dilution of US$                     per ADS. See “Dilution.”

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 and cash equivalents and cash flow from operations will be sufficient to meet our anticipated cash needs for the next 12 months. 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 you that financing will be available in amounts or on terms acceptable to us, if at all.

Substantial future sales of our ADSs in the public market could cause the price of our ADSs to decline.

          Additional sales of our ordinary shares in the public market after this offering, or the perception that these sales could occur, could cause the market price of our ADSs to decline. Upon completion of this offering, we will have                      ordinary shares outstanding. All shares sold in this offering will be freely transferable without restriction or additional registration under the Securities Act of 1933. The remaining                     ordinary shares outstanding after this offering will be available for sale, upon the expiration of the 180-day lockup period beginning from the closing of this offering, subject to volume and other restrictions as applicable under Rule 144 and 701 under the Securities Act. Any or all of these shares may be released prior to expiration of the lockup period at the discretion of Merrill Lynch & Co. To the extent shares are released before the expiration of the lockup period and these shares are sold into the market, the market price of our ADSs could decline.

          In addition, certain holders of our ordinary shares after the completion of this offering will have the right to cause us to register the sale of            million shares under the Securities Act. Registration of these shares under the Securities Act would result in these shares becoming freely tradable without restriction under the Securities Act immediately upon the effectiveness of the registration. Sales of these registered shares in the public market could cause the price of our ADSs to decline.

You 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 your right to vote.

          Except as described in this prospectus 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 have the right to instruct the depositary 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

You may not be able to participate in rights offerings and may experience dilution of your holdings as a result.

          We may from time to time distribute rights to our shareholders, including rights to acquire our securities. Under the deposit agreement for the ADSs, the depositary will not offer those rights to ADS holders unless both the rights and the underlying securities to be distributed to ADS holders are either registered under the Securities Act of 1933, as amended, or exempt from registration under the Securities Act with respect to all holders of ADSs. We are under no obligation to file a registration statement with respect to any such rights or underlying securities or to endeavor to cause such a registration statement to be declared effective. In addition, we may not be able to take advantage of any exemptions from registration under the Securities Act. Accordingly, holders of our ADSs may be unable to participate in our rights offerings and may experience dilution in their holdings as a result.

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

          Your ADSs represented by the ADRs 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 substantially all 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 substantially all of our operations in China through our subsidiaries in China. Most of our directors and officers reside outside the United States and some or all of the assets of those persons 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 to enforce or protect your rights under the securities laws or otherwise. Even if you are successful in bringing an action of this kind, you may be unable to enforce a judgment against our assets or the assets of our directors and officers under the laws of the Cayman Islands and of China. 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 monetary judgment of a foreign court of competent jurisdiction without retrial on the merits. For more information regarding the relevant laws of the Cayman Islands and China, see “Enforceability of Civil Liabilities.”

          Our corporate affairs are governed by our memorandum and articles of association 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 of all of the above, our public shareholders may have more difficulty in protecting their interests through actions against our management, directors or major shareholders than would shareholders of a corporation incorporated in a jurisdiction in the United States.

We have considerable discretion in the application of the net proceeds of this offering, and we may use the proceeds in ways with which you may not agree.

          Our management will have considerable discretion in the application of the net proceeds received by us. You will not have the opportunity, as part of your investment decision, to assess whether proceeds are being used appropriately. You must rely on the judgment of our management regarding the application of the net proceeds of this offering. The net proceeds may be used for corporate purposes that do not improve our efforts to maintain profitability or increase our share price. The net proceeds from this offering may be placed in investments that do not produce income or that lose value.

We are controlled by a small group of our existing shareholders, whose interests may differ from other shareholders.

          The family trusts of our four senior officers beneficially own approximately 68.9% of the outstanding ordinary shares of our company, assuming the conversion of the outstanding convertible notes into ordinary shares, and will beneficially own approximately                     % of our outstanding ordinary shares immediately following this offering. Mr. Defu Dong, our Chairman and Chief Executive Officer, has sole power to vote on behalf of these trusts over matters requiring approval by our shareholders, including electing directors and approving mergers or other business combination transactions. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and might reduce the price of our ADSs. These actions may be taken even if they are opposed by our other shareholders, including those who purchase shares in this offering.

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

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

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.

          We do not expect to be considered a “passive foreign investment company,” or PFIC, for United States federal income tax purposes for our taxable year ending December 31, 2005. Such characterization could result in adverse U.S. tax consequences to you if you are an U.S. investor. For example, if we are a passive foreign investment company, our U.S. investors will become subject to increased tax liabilities under U.S. tax laws and regulations and will be subject to burdensome reporting requirements. However, we must make a separate determination each year as to whether we are a PFIC and we cannot assure you that we will not be a PFIC for our taxable year ending December 31, 2005 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 market value of our assets may be determined in large part by the market price of our ADSs and ordinary shares, which is likely to fluctuate after the offering (and may fluctuate considerably given that market prices of technology companies have been especially volatile). In addition, the composition of our income and assets will be affected by how, and how quickly, we spend the cash we raise in this offering. If we were treated as a PFIC for any taxable year during which a U.S. holder held an ADS or an ordinary share, certain adverse United States federal income tax consequences could apply to the U.S. holder. See “Taxation — United States Federal Income Taxation — Passive Foreign Investment Company.”
