|(2) | All share and per share data have been presented to give retrospective effect to our reorganization.
|--- | ----------------------------------------------------------------------------------------------------

|(3) | Our company issued 1,800,000,000 ordinary shares in August 2006 in connection with our reorganization in 2006. For the purposes of calculating basic and diluted
earnings per ordinary share, the number of ordinary shares used in the calculation reflects the issuance of ordinary shares as if the reorganization took place as of the beginning of the earliest period presented.

|(4) | In November 2009, we acquired 100% equity interest of Jiangsu Kangpeng Nong Hua Limited, or Kangpeng Nong Hua, for RMB25 million (US$3.7 million) in cash. As our
Chairman and CEO, Dr. Yang held more than 50% voting ownership interest of both the Company and Kangpeng Nong Hua at the date of the acquisition, it was considered a transaction between entities under common control. Therefore, our consolidated
financial statements have been retroactively adjusted to reflect the combined entities for the periods during which the entities were under common control.

Risks Related to Our Company and Our Industry

If we are unable to manage our growth effectively, our business, financial condition and operating results could be harmed.

We have experienced rapid growth, especially since 2003, which has required us to expand our operations and make
increasing investments in our management, administrative, operational and financial infrastructure. For example, the number of our employees increased from 118 as of January 1, 2003 to 1,794 as of December 31, 2010. Furthermore, our sales
increased from RMB68.9 million in 2003 to RMB1,082.0 million (US$163.9 million) in 2010. Rapid expansion has placed strain on our management resources and may have led to inefficiencies in our administrative systems or business operations, some of
which we have not yet discovered or addressed. It has also placed a strain on our ability to expand manufacturing facilities that can satisfy the increasing number of orders we receive. While our customers typically give us an estimated production
plan for a period of two to twelve months, those estimates are not binding. Typically, it takes two to three years from the time that we acquire the land for a production facility for that production facility to begin operations. The relatively
short lead-time and non-binding nature of the production estimates that we receive from our customers and the relatively long and capital-intensive process involved in creating new production capacity have made it difficult to anticipate needed
production capacity. For example, the lack of growth of our revenues and our net income from 2006 to 2007 resulted in part from the fact that we were producing at or near maximum capacity and were not rolling out our new production facility until
late in 2007. In addition, the decline of our revenues in 2009 from 2008 resulted mainly from the impact of the global financial crisis and economic recession. Despite the temporary decline we experienced in 2009, we expect our business to continue
to expand significantly as the global economy continues to recover and demand for specialty chemicals in our industry increases. While we increased our production capacity when we opened our new production facilities since late 2007 and through our
acquisition of Jiangsu Wei Er in February 2008, we may in the future face periods of increasing demand in which we are unable to address increasing orders. Our future prospects will depend in part on the ability of our senior management to
successfully manage our operations so that we are able to capitalize on any growth opportunities that arise. In order to be positioned to take advantage of any future growth opportunities that may arise, we must take, among other actions, some or
all of the following actions:



| |  |  | increase production capacity and further renovate our production facilities, either at our existing facilities or through the construction or purchase
of additional facilities;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | keep up with evolving industry standards, technologies and market developments, expand research and development capabilities and continue to improve
our engineering and manufacturing processes;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | improve our existing, or implement additional, operational and financial systems, procedures and controls;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | increase awareness of our brand name, protect our reputation and expand our sales and marketing network and capability in order to further deepen and
broaden our business scale and scope;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | attract, train and retain qualified research and development and operational employees and manage our rapidly growing employee base;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | retain our key relationships with government agencies, obtain and maintain any governmental approvals required for our business, including current and
future product offerings, and respond to changes in the regulatory and policy environment; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | integrate any acquired businesses into our operations and realize the potential benefit of our acquisitions.
| | - |  | ------------------------------------------------------------------------------------------------------------

Furthermore, we need to maintain, expand and diversify our relationships with our existing and new customers, suppliers and other third
parties. If our current and planned operations, personnel, systems, internal procedures and controls are not adequate to support our recent and future growth, then our business and financial condition could be adversely affected. In addition, the
success of our growth strategy depends on a number of internal and external factors, such as raw material costs, our ability to increase production capacity and output

and our ability to develop and commercialize new products together with our customers and end users. If we are unable to manage our growth effectively, we may not be able to take advantage of
market opportunities, execute our business strategies or respond to competitive pressures.

Our operating history with
our current scale and product mix may not serve as an adequate basis to judge our future prospects and results of operations.

Our product mix varies frequently from year to year in accordance with the specific demands and industry of the end users of our products. This in turn can lead to fluctuations in our sales. We had sales
of RMB942.5 million, RMB820.3 million and RMB1,082.0 million (US$163.9 million) and net income attributable to our shareholders of RMB312.4 million, RMB172.4 million and RMB225.5 million (US$34.2 million) in 2008, 2009 and 2010, respectively. In the
event that we are unable to expand our business and increase our sales, we may not achieve similar results in future periods. Accordingly, you should not rely on our past results or historical growth rate as an indication of our current or future
business, financial performance and prospects.

Among other factors and limitations, you should consider our future prospects
in light of the risks and uncertainties experienced by a specialty chemicals company, which is based in China. These risks include, among others, the risk that we will be unable to:



| |  |  | retain existing customers and obtain new customers;
| | - |  | ---------------------------------------------------



| |  |  | diversify our revenue sources by successfully identifying market opportunities, developing technologies and processes, achieving economies of scale and
commercializing our pipeline products;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | expand our business and effectively manage our business as it expands;
| | - |  | ----------------------------------------------------------------------



| |  |  | anticipate and respond in a successful and timely way to changes in technology, market developments and regulatory environment;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | obtain on commercially reasonable terms the licenses required to operate and expand our business;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | protect our intellectual property and our customers intellectual property and manage risks associated with intellectual property rights;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintain effective control of our costs and expenses;
| | - |  | -----------------------------------------------------



| |  |  | raise sufficient capital to sustain and expand our business; and
| | - |  | ----------------------------------------------------------------



| |  |  | attract, retain and motivate qualified personnel.
| | - |  | -------------------------------------------------

If we are unsuccessful in addressing any of these risks and uncertainties, our prospects, business, financial condition, results of operations and future growth would be adversely affected.

If the end markets for our specialty chemicals decline or do not grow as quickly as we anticipate, or if our customers do not
succeed in increasing their market shares in those markets, our business prospects and results of operations could be harmed.

Demand for our products is dependent on demand for the end products that incorporate our products. Most of those end users are in the electronics, pharmaceuticals and agrochemicals industries. While some
of our sales are to direct end users, a significant percentage of our sales are made to trading companies that act as middlemen and sell our products to end users for multiple industry applications. Due to this sales model, there is a degree of
uncertainty about the identity of the ultimate end users of some of our products, the industries in which our products are used and our estimates of the approximate percentages of sales derived from each end market into which we sell our products.
The largest percentage of our sales has historically been derived from products used in the electronics industry, particularly in the manufacture of TFT-LCDs. Historically, the second largest percentage of our sales has been derived from products
used in the pharmaceuticals industry and this sector has been increasing in importance to our business. Although it has historically been the smallest source of sales of

our products, the agrochemicals industry has also been increasing in importance to our business over time, except in the second half of 2009 because the global agrochemical business deteriorates
as a result of the global economic recession and unfavorable weather patterns in some major farming markets. Our future success depends on the continued growth of these markets as well as the growth, viability and financial stability of our
customers and end users and the end-market demand for our customers products. If the end markets for our specialty chemicals decline or do not grow as quickly as we anticipate, just like what we experienced in the first quarter of 2009 for the
electronics chemical market and the second half of 2009 for the agrochemical market, or if our customers do not succeed in increasing their market shares in those markets, our business prospects, financial condition and results of operations could
be harmed. In particular, the end markets for our products, the electronics, pharmaceutical and agrochemical industries, are characterized by rapid technological changes, short product life cycles, vigorous competition, consolidation and/or pricing
and margin pressures. Significant decreases in demand for consumer electronics, beginning in the second half of 2008 brought on by the global economic downturn resulted in decreases in demand for our specialty chemicals used in the manufacture of
TFT-LCDs in 2009, particularly in the first quarter of 2009. In addition, significant decreases in demand for agrochemicals beginning in the second half of 2009 brought on by the global economic recession resulted in decreases in demand for our
specialty chemicals used in the agrochemical market in the second half of 2009. Therefore, although we had seen a strong recovery in demand for our products in 2010, especially in the electronics chemical market, the increase in sales of our
products resulting from anticipated growth in these industries may be less than expected or may fail to materialize altogether if the global economic condition changes. If anticipated growth occurs at a slower rate than expected or fails to occur at
all, our strategy to expand our business by continuing to expand into these end markets may not be successful, which could have a material adverse effect on our business. If any of these risks materialize, we may not grow or our growth may slow and
our business, financial condition and operating results could be materially harmed.

We may prove unsuccessful in our
ability to manage increased manufacturing capacity and increased research and development capability and we may not realize the anticipated benefits from either or both of these expansions.

We manufacture all of our products and conduct our research and development activities in our facilities in China. We have built a new
research and development center and head office building in Shanghai that significantly increased our research and development capabilities. We also have expanded, and continue to expand our manufacturing capacity at our existing facilities and
through the addition of new facilities. As of December 31, 2010, we owned and operated six major production facilities with a total maximum production capacity of 2.3 million liters of reactor volume. We must continue to devote significant
resources to the expansion of our manufacturing capacity. These planned expansions will be expensive, will require a significant amount of managements time that could otherwise be used in other aspects of our business and may disrupt our
operations. We will incur these costs, which may be higher than we anticipate, as well as continuing costs of maintenance and operations for these facilities, even if we are unable to utilize the increased capacity and capability due to decreases in
demand for our products, reduced sales volumes or otherwise.

Additional risks associated with increasing our manufacturing
capacity and research and development capabilities include:



| |  |  | inability to attract and retain manufacturing personnel and research and development engineers or shortages of such personnel;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | difficulties in achieving adequate yields or quality control from new or expanded manufacturing facilities;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | inability to quickly implement an adequate set of financial controls to track the increased scale of our business;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | lack of trained personnel to manage the operations and customer contracts appropriately;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | wage inflation and unfavorable exchange rates;
| | - |  | ----------------------------------------------

| |  |  | maintaining customer, supplier and other favorable business relationships;
| | - |  | --------------------------------------------------------------------------



| |  |  | effective training of staff to manage new customers and products;
| | - |  | -----------------------------------------------------------------



| |  |  | unanticipated disruptions in our operations which may impact our ability to make timely deliveries to our customers, produce quality products and
ensure overall customer satisfaction;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | delays in commencing operations at our new and expanded facilities; and
| | - |  | -----------------------------------------------------------------------



| |  |  | costs required to procure all necessary equipment for these projects and expansion, which may be higher than anticipated.
| | - |  | -------------------------------------------------------------------------------------------------------------------------

In the event that we are unsuccessful in our ability to manage and utilize this increased capacity and capability, or if the delays,
disruption, or costs related to these projects are greater than we anticipate, our business, financial condition and operating results could be harmed.

Our products, in particular our commercialized projects, may be subject to decreasing pricing trends and reduced margins in the future. If we are unable to successfully replace these products
subject to those trends with newer, more profitable products, our sales and future results of operations could be harmed.

Many specialty chemicals, including those that we manufacture, are subject to price declines over time due to competitive forces, while manufacturing and material costs may remain constant or increase. In
particular, our average selling price of our commercialized products decreased from RMB444, 000 per metric ton in 2008 to RMB308, 000 per metric ton in 2009. Although the average selling price of our commercialized products increased to RMB 424,000
(US$64,171) per metric ton in 2010, as some of our products enter into a later stage in their lifecycles, the average selling prices of those products may decrease.

In addition, many of the raw materials we use, particularly petroleum-based chemicals and solvents, fluorine and hydrofluoric acid, have been subject to significant price fluctuations in recent years. As
a result of the decline in average selling prices for our commercialized products and the fluctuations in the cost of the raw materials that we use to produce those products, margins for some of our specialty chemicals have declined and may continue
to decline over time. We must continuously transition our product range to newer, more advanced specialty chemicals to command higher margins to maintain our growth and profitability and to offset rising raw material costs. Our profitability also
depends on our ability to successfully control costs during the manufacturing process by continuing to increase the efficiency of our manufacturing processes, reduce raw material consumption and increase production yields. In addition, changes in
our product mix or production of products with lower average selling prices by new or acquired facilities may negatively affect our overall average selling prices. If we are unable to successfully design, manufacture and market new products that
command higher average selling prices, or if we fail to effectively increase the efficiency of our manufacturing processes, continue to control manufacturing costs or shift new or acquired facilities to higher value-added products, our business,
financial condition and operating results could be harmed.

Our operating results may fluctuate considerably on a
quarterly basis. These fluctuations could have an adverse effect on the price of our shares and ADSs.

Our results of
operations have fluctuated in the past and may continue to fluctuate significantly on a quarterly basis as a result of a number of factors, many of which are beyond our control. Although many companies may encounter fluctuations in their results of
operations, these fluctuations are particularly relevant to us as a result of our current reliance on a limited number of customers, our reliance on purchase orders rather than long-term contracts with our customers, our relatively small size, our
limited operating history and the dynamics of operating a business in China. Factors that could cause our results of operations to fluctuate include, among others:



| |  |  | seasonal or periodic fluctuations in our customers and end users businesses, which could cause the timing of their purchases of our
products to vary;

| |  |  | international or China-specific economic downturns.
| | - |  | ---------------------------------------------------

A number of these effects are most noticeable in the first quarter of a non-recession business year, which is when we generally experience lower demand for our products, in particular commercialized
products, than in other quarters.

In addition, as we generally do not enter into long-term contracts with our customers, any
decision by one or more of them to reduce or terminate orders during a certain period of time could have an adverse effect on our sales for those periods. We base our planned operating expenses in part on our expectations of future revenue, and as a
result, a significant portion of our expenses will be fixed in the short term. If revenue for a particular quarter is lower than we expect, we likely will be unable to proportionately reduce our operating expenses for that quarter, which would have
a material adverse effect on our operating results for that quarter. You should not rely on our results from any quarter as an indication of future performance. Quarterly variations in our operations could result in significant volatility in the
market for our ADSs, and the market price for our ADSs might fall.

Furthermore, the occurrence of any of the risks described above could result in harm to our
business, financial condition and operating results, especially if it continues for a period of time or is not mitigated in subsequent periods.

Our current dependence on a limited number of customers may cause significant fluctuations or declines in our revenues.

We currently derive the substantial majority of our sales from a limited number of customers. Our customers consist of the actual end
users of our products as well as trading companies that sell our specialty chemicals to third parties. In 2008, 2009 and 2010, aggregate sales to our three largest customers represented approximately 65%, 61% and 65% of our total sales,
respectively. Our three largest customers in 2008, 2009 and 2010, each individually accounted for more than 7% of our sales, while our single largest customer accounted for 35%, 24% and 33% of our total sales in 2008, 2009 and 2010, respectively. In
addition, some of our end users purchase our products indirectly through one or more of our customers that are trading companies. We are unable to fully assess the exact amount of such indirect sales although we are aware of the occurrence of these
situations based on various discussions with certain of our end users and customers. Based on the assessments of the amount of sales to our single largest end user, including both direct purchases from us and indirect purchases through trading
companies, the percentage of sales accounted for by that end user is larger than the figures indicated above for our single largest customer. Due to the concentration of our business and dependence on a limited number of customers and end users, any
one or more of the following events, among others, some of which we experienced in 2010, may cause material fluctuations or declines in our revenues and have a material adverse effect on our financial condition, results of operations and prospects:



| |  |  | reduction, delay or cancellation of orders or contracts from one or more of our significant customers, and our failure to identify additional or
replacement customers;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | reduction, delay or cancellation of orders to our customers from one or more of the companies to which they sell our products, due to a reduction in
their customers product sales or otherwise;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the decision by one or more of our significant customers to select one or more of our competitors to supply their specialty chemicals needs;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | loss of one or more of our significant customers and our failure to obtain additional or replacement customers that can replace the lost sales volume
at satisfactory pricing, production and other terms;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | reduction in the price that one or more of our significant customers is willing to pay for our products;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | any adverse change in the bilateral or multilateral trade relationships among China, the United States, Japan and European countries that could cause
us to lose access to certain customers or make such access more difficult; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the failure or inability of any of our significant customers to make timely payment for our products.
| | - |  | -----------------------------------------------------------------------------------------------------

We anticipate that our dependence on a limited number of customers will continue in the foreseeable future although we have been doing
our best in recent years to diversify our customer base. In addition, as we generally do not enter into long-term contracts with customers, but receive purchase orders based on the specific needs of our customers, we are frequently subject to the
renegotiation of pricing and other terms. We have and may continue to be required to reduce our average selling price in response to competitive pricing pressures. We also do not typically obtain firm purchase orders or commitments from our
customers for extended periods. These factors may result in a lack of certainty and predictability about our sales, which may fluctuate unpredictably depending on customer demand and orders. Although we have historically retained many of our largest
customers for extended periods, we cannot be certain whether these customer relationships will continue to develop or if these customers will continue to generate significant revenue for us in the future.

In addition, while we work closely with our customers to develop forecasts for periods of up to one year, these forecasts are not binding
and may be unreliable. Customers may cancel their orders, change production

quantities from forecasted volumes or delay production for a number of reasons beyond our control, which could materially and adversely affect our sales and results of operations. The short-term
nature of our customers commitments and the possibility of rapid changes in demand for their products also reduce our ability to accurately estimate the future requirements of our customers. The difficultly of forecasting the level of customer
orders with certainty makes it difficult to schedule production, order appropriate levels of materials and maximize the utilization of our manufacturing capacity. This could also lead to an inability to meet production demands, which could harm our
business, financial condition and operating results.

Our current business and future growth depend in part upon the
level of regulatory and commercial success of the end products incorporating our specialty chemicals. If those end products experience regulatory or commercial setbacks, related expenditures and development activities may fall short of our
expectations and our business, financial condition and results of operations may be harmed.

Many of the orders we
receive are for specialty chemicals used in products still in the development stage or at an early stage of marketing, some of which are subject to regulatory review and approval. Whether those products receive such required approvals and ultimately
pass through the test stage and reach a level of commercial production will significantly affect our future sales as we continue to provide specialty chemicals to those customers and end users. In particular, certain of our specialty chemicals are
used as intermediates for the research and development of new pharmaceutical and agrochemical compounds. As pharmaceutical and agrochemical companies seek to develop new drugs and agrochemical products that will be successful in the marketplace,
they conduct extensive research and development. We supply pharmaceutical and agrochemical companies with pilot quantities of novel specialty chemicals for use in their research for commercial production and clinical development. If those products
prove effective, obtain governmental approval and achieve marketing success in the future, we may be able to supply them with larger quantities of specialty chemicals. However, if the products which use our specialty chemicals do not prove
effective, fail to receive regulatory approval or fail to achieve commercial success, we will not be able to increase our sales of those specialty chemicals, which could materially and adversely affect our growth prospects.

If the companies that use our products change their production processes, demand for our specialty chemicals could decline, and our
business, financial condition and results of operations could be harmed.

Our specialty chemicals are used in a range
of applications. Changes in the production processes used by our customers or the companies that purchase their products could reduce or eliminate demand for the specialty chemicals that we produce or make our specialty chemicals unnecessary.
Companies that use our specialty chemicals may also decide to produce or purchase alternative materials or use production processes that no longer require our products. If such a change were to occur, whether due to price, performance or other
considerations, we might not be able to supply specialty chemicals that meet those new requirements. For example, the markets for electronics and pharmaceuticals, where many of our specialty chemicals have been used in recent years, are rapidly
evolving and demand for our specialty chemicals that are used in these markets could change quickly. Our business, results of operations, and financial condition could be materially and adversely affected if we were unable to successfully adapt to
such changes in a timely or cost-effective manner.

Our business and prospects depend on our ability to successfully
identify market opportunities for new products, develop new technologies and develop and implement manufacturing processes for commercial production of the new products. If we are not successful in expanding our sales into new product lines, our
business, financial condition and results of operations could be harmed.

Our business model depends on our ability to
successfully identify specialty chemicals with significant market opportunities for end users, develop new technologies and develop and implement manufacturing processes for commercial production. The manufacture of new and technologically advanced
products involves complex and uncertain processes requiring highly skilled engineering and development personnel. If we are unable to successfully develop these products or processes or if the benefits from developing them prove to be

less than anticipated, our growth may slow or stall, and we may incur costs that are not offset by sales from the new specialty chemicals. Even if we correctly identify specialty chemicals that
offer significant market opportunities, we may be unable to produce new products in a commercially viable manner, if at all.

The applications for specialty chemicals are characterized by rapid technological advances. Our technologies, processes and products may
become uncompetitive or obsolete if we are less successful at adapting to new technologies, new processes, new products, changes in customer demand or changes in customer requirements than our competitors. In order to keep pace with technological
advances and to retain our competitive position, we will need to invest substantial financial resources to improve our technologies and production processes. If we fail to commercialize our research and development results or to improve our
technologies and production processes, we may become less competitive and our results of operations may be negatively affected.

A payment failure or cancellation of purchase orders at a late stage by any of our large customers could significantly harm our
cash flows and results of operations.

Consistent with industry practice, under many of our purchase orders with our
customers, we offer 30 to 120 days sales credit terms to our customers, unless we receive collateral for the payment obligations. Historically, we have not experienced any significant delay, refusal or inability of our major customers to make timely
payments to us, but payment problems may arise in the future. If any of our customers fails to make timely payments, we could experience delays in our cash receivables, incur costs to collect overdue payments, write off accounts receivable or
increase provisions made against our accounts receivable, which could adversely affect our cash flows and results of operations.

In the event that we are unable to obtain raw materials in a timely manner and at reasonable prices, our business, financial condition and results of operations would be harmed.

Raw materials accounted for 86.8%, 77.0% and 74.1% of our cost of sales in 2008, 2009 and 2010, respectively. In addition, raw material
costs accounted for 50.5%, 46.5% and 45.5% of our sales in those periods, respectively. While the factors affecting the prices of our raw materials are difficult to predict, changes in the price of raw materials may have a significant impact on our
cost of sales. In recent years, the prices of fluorine, hydrofluoric acid, petroleum-based solvents and many of the other raw materials we use have fluctuated significantly. We expect raw material prices to continue to increase as the global economy
recovers. In the event that raw material prices increase above certain levels, the continued production of our products may become uneconomical. Our inability to fully offset the effects of higher raw material costs or to obtain such raw materials
on pricing and other terms satisfactory to us could have a material and adverse effect on our financial condition and results of operations.

If we are unable to secure adequate amounts of necessary raw materials, it may limit or prevent us from delivering our specialty chemicals in a timely manner to our customers in the required quantities
and at competitive prices, which could result in order cancellations, decreased revenue and loss of market share. We have not entered into any long-term agreements with our suppliers. If we fail to maintain our relationships with our current
suppliers or develop relationships with our suppliers on pricing and other terms that are satisfactory to us, or if a supplier fails to supply raw materials that meet our quality, quantity and cost requirements, we may be unable to fill our
customers orders on a timely and cost-effective basis, which could result in order cancellations, decreased revenue, loss of market share and damage to our reputation.

In the event that the third parties who supply chemical components for our specialty chemicals are unable to deliver those chemical components in a timely manner and at a sufficient quality level,
our business, reputation and results of operations could be harmed.

Some of the chemical building blocks involved in
the manufacture of specialty chemicals we produce are commodity chemicals, the manufacture of which does not require advanced process or manufacturing

expertise. In order to focus on our core competencies, we outsource some of the less advanced production to third-party manufacturers who provide us with components for use in our manufacturing
processes. We believe this arrangement is more efficient and economical than producing these chemicals ourselves. While we monitor the quality of the chemical components we receive and carefully select our vendors, we cannot guarantee the quality or
timely delivery of the chemical components produced by those vendors. If our vendors fail to timely deliver those chemical components, or if those components are of inadequate quality, our own production could be delayed. While we generally have not
experienced problems with quality or timeliness in delivery by these third-party suppliers, we cannot ensure that such problems or delays will not occur in the future. If we experience problems with the quality of outsourced chemical components we
purchase or delays in the delivery by these third-party suppliers, our ability to produce and deliver satisfactory quality products in a timely way using those chemicals could be compromised, which could harm our reputation, business and results of
operations.

We have limited insurance coverage.

The insurance industry in China is still at an early stage of development. Insurance companies in China offer limited insurance products.
As of December 31, 2010, we carried approximately RMB891.7 million (US$135.1 million) of insurance coverage, which includes coverage for certain of our property, plant and equipment and inventory and for employee injury and third-party
liability for all of our operations. We also have a directors and officers, or D&O, insurance with US$10 million coverage. We do not have insurance coverage on our other assets and we do not have insurance to cover our business or interruption
of our business, other types of litigation or product liability. We have determined that the costs of insuring for these risks and the difficulties associated with acquiring such insurance on commercially reasonable terms make it impractical for us
to have such insurance. Any uninsured occurrence of loss or damage to property, litigation or business disruption may result in our incurring substantial costs and the diversion of resources, which could have an adverse effect on our operating
results and financial condition.

We face risks associated with the marketing and sale of our specialty chemicals
internationally, and the failure to effectively manage these risks could materially and adversely affect our business, prospects, financial condition and results of operations.

In 2008, 2009 and 2010, sales to customers outside of China represented approximately 48.7%, 55.8% and 51.0% of our sales, respectively.
These figures include sales made to Japan, which constituted 36.1%, 51.0% and 60.4% of our sales made outside of China and 17.6%, 28.5% and 31.2% of our total sales in 2008, 2009 and 2010, respectively. The majority of our products sold to
China-based trading companies, which we account for as domestic sales, are ultimately sold to end users in international markets such as Japan, the United States and Europe. We anticipate that revenues derived internationally will continue to be
significant to our sales in the near future. The marketing and sale of our products in the international market expose us to a number of risks, including, among others, the following:



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



| |  |  | trade disputes between China and other jurisdictions such as Japan, the United States and Europe;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | fluctuations in currency exchange rates;
| | - |  | ----------------------------------------



| |  |  | increased costs associated with maintaining marketing and selling efforts in various countries;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | increased shipping costs; and
| | - |  | -----------------------------



| |  |  | difficulties and costs related to compliance with the different commercial, environmental and other legal requirements in the various international
markets in which we sell our products.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Furthermore, the geographic concentration of our sales in Japan heightens these risks with
respect to that region. If any of these risks materialize with respect to Japan, or if economic conditions generally worsen there, or in the event of a natural disaster there, our results may be disproportionately affected and our business may be
harmed and we may experience losses. In March 2011, Japan was struck by a 9.0-magnitude earthquake. Although the earthquake together with the resulting tsunami and radiation leak at the Fukushima nuclear power plant have not had an immediate direct
impact on our operations, we cannot assure you that these events will not have any subsequent adverse effect on our industry. The extent of existing and potential future radiation release from the Fukushima nuclear power plant is still in flux and
coupled with potential aftershocks from the earthquake, may result in future additional adverse effects on the operations of our customers. Our customers with facilities and operations in Japan or who have business dealings with Japan that have been
affected by these events may suffer from a slowdown resulting in reduced demand for our services and we can make no assurances that our results of operations will not be adversely affected.

The occurrence of one or more of these risks could materially and adversely affect our business, prospects, financial condition and
results of operations.

If we are unable to compete successfully against our current and future competitors, many of
which have greater name recognition, resources, experience and larger customer bases than we do, our business, financial condition and results of operations could be harmed.

We compete against a number of Chinese specialty chemicals producers, such as WuXi PharmaTech Co., Ltd., Asymchem Laboratories Co., Ltd.,
Xian Ruilian Modern Electronic Chemicals Co., Ltd., Yantai Valiant Fine Chemicals Co., Ltd., and Zhejiang Yongtai Chemical Co., Ltd., and foreign specialty chemicals producers, such as Lonza Group Ltd., Evonik Degussa GmbH, Lanxess AG, Balchem
Corporation, Rohm and Haas Company, and Sigma-Aldrich Corporation. We face competition based on a number of factors, including quality, timeliness, good manufacturing practices, depth of customer relationships, pricing, geography and ability to
protect confidential information and intellectual property. Many of our competitors have longer operating histories, economies of scale, greater name recognition, larger customer bases and significantly greater financial, sales and marketing,
production, distribution, technical and other resources and experience than we do. Our competitors greater size in some cases provides them with greater pricing flexibility and a competitive advantage with respect to production costs due to
greater economies of scale and their ability to purchase raw materials and utilities at lower prices. In addition, our competitors may be able to devote greater resources to the research and development of technologies, processes and products that
are more effective than ours, and that may render our technologies, processes or products obsolete or uneconomical. They may also adapt more quickly to new or emerging technologies and changes in customer demand and requirements. In addition, new
competitors or alliances among our competitors could emerge and rapidly acquire significant market share. Our failure to maintain a competitive position with respect to technological advances, adapt to changing market conditions or otherwise compete
successfully with existing or new competitors could have a material and adverse effect on our business, financial condition and results of operations. In addition, as more Chinese and international chemical manufacturers continue to invest in China
and take advantage of lower production and labor costs in China, we may face increasing pricing pressure and decreasing demand for our products and services as well as increasing competition for qualified personnel, which could have a material and
adverse effect on our business, financial condition and results of operations.

We also expect increasing competition as new
companies enter the market and more advanced technologies become available. Our products and expertise may be rendered obsolete or uneconomical by technological advances or new approaches. The current or future technologies used or developed by our
competitors may be more effective or advanced than those used and developed by us. Furthermore, increasing competition increases pricing pressure for our products, which can reduce our profit margins on the products we sell and have a material and
adverse effect on our business, financial condition and results of operations.

Our use, production and disposal of hazardous materials subject us to stringent
environmental, health and safety regulations. Any actual or alleged violation of these regulations could result in significant regulatory actions, fines and other penalties, including suspending production or ceasing operations, substantial civil or
criminal claims resulting in potentially significant monetary damages, adverse publicity, and other negative consequences to our business.

Because we use, produce and dispose of hazardous materials and our production processes generate noise, waste water, gaseous and other industrial wastes, we are required to comply with national and local
environmental, health and safety regulations applicable to us. We believe that we have instituted environmental, health and safety procedures and measures that meet or exceed the standards prescribed by national, provincial and local regulations in
China. However, we cannot completely eliminate the environmental, health and safety risks associated with our use, production and disposal of hazardous materials and we have experienced environmental, health and safety incidents at our facilities in
the past, including fires, leakages and other accidents, which have resulted in regulatory actions requiring us to take corrective actions and subjected us to fines and other penalties. In some cases, we have been required to temporarily suspend
production or cease operations while we performed corrective actions. We believe we are currently in compliance with applicable environmental, health and safety regulations in all material aspects and have all necessary environmental, health and
safety permits to operate our business as it is presently conducted. However, if more stringent regulations are adopted in the future, the costs of compliance with these new regulations could be substantial. If we fail to comply with present or
future environmental, health and safety regulations, we may be subject to significant regulatory actions, fines and other penalties, including suspending production or ceasing operations, substantial civil or criminal claims resulting in potentially
significant monetary damages, adverse publicity, and other negative consequences to our business, all of which could have a material adverse affect on our business, reputation, financial condition and results of operations.

Our operations are subject to various risks associated with our use, handling, storage and disposal of hazardous materials, many of
which are toxic and flammable. If we are found liable for contamination, injury to employees or others, or other harms related to our use, handling, storage and disposal of hazardous materials, our business, reputation, financial condition and
results of operations may be adversely affected.

We use, handle, store and dispose of hazardous materials in our
operations, many of which are toxic and flammable. We believe that we have been diligent in designing and implementing procedures and measures to promote occupational health and safety in compliance with the standards prescribed by national,
provincial and local regulations in China. However, we cannot completely eliminate the risks of contamination, injury to employees or others, or other harms related to our use, handling, storage and disposal of hazardous materials. We have
experienced incidents in the past, including fires, leakages and other accidents, and there can be no assurance that such incidents will not occur in the future. In the event of future incidents, we could be liable for any damages that result,
including potentially significant monetary damages for any civil litigation or government proceedings related to a personal injury claim, as well as other fines, penalties and other consequences, including suspension or revocation of our licenses or
permits or suspending production or ceasing operations at our research and manufacturing facilities, all of which could have a material adverse affect on our business, reputation, financial condition and results of operations. Furthermore, we
currently do not carry any insurance coverage for potential liabilities relating to the release of hazardous materials and any release of hazardous materials could cause us further harm.

Our failure to obtain and maintain permits, licenses and registrations necessary to conduct our business could materially harm our
business and prospects.

We use hazardous chemicals that are subject to regulation by many national, provincial and
local governmental authorities in China. As we grow, we may become subject to additional regulation or higher compliance standards.

In order to obtain regulatory approval of certain new products and production processes, we
must, among other things, demonstrate to the relevant authorities that the product is safe for its intended uses and that we are capable of manufacturing the product in accordance with applicable regulations. The process of seeking approvals can be
time consuming and subject to unanticipated and significant delays. Approvals may not be granted to us on a timely basis, or at all. Any delay in obtaining, or any failure to obtain or maintain, these approvals would adversely affect our ability to
introduce new products and to generate revenue from those products. In addition, some of these licenses and permits are subject to periodic renewal. Failure to obtain or maintain any of these permits and licenses could have a material adverse effect
on our business and prospects. New laws and regulations may be introduced in the future that could result in additional compliance costs, seizures, confiscation, recall or monetary fines, any of which could prevent or inhibit the development,
distribution and sale of our products.

Our business and operations are subject to business interruption risks due to
the actions of third parties, which could have a material adverse effect on our business, reputation, financial condition and results of operations.

Due to the nature of our business, we are at risk of business interruption due to the actions of third parties. For example, many of our vendors and subcontractors have operations that are also subject to
environmental, health and safety risks associated with the use of hazardous materials. Some of our vendors and subcontractors are, or have been related parties to us, and have experienced environmental, health and safety incidents in the past that
have impacted us, including an explosion at a third party facility that resulted in the death of one of our employees in 2007. In addition, we may be adversely impacted by incidents at unrelated facilities. For example, Jiangsu Wei Er was ordered to
shut down following an accident at an unrelated facility located in the same industrial park while local authorities investigated the accident in 2008. Any future environmental, health and safety incidents affecting our vendors and subcontractors
may result in significant regulatory actions, fines and other penalties, including restrictions, prohibitions or sanctions on their operations, and could impair their ability to perform their contracts with us or could otherwise subject us to
liability, all of which could have a material adverse affect on our business, reputation, financial condition and results of operations. In addition, there can be no assurance that we will not be adversely affected by incidents at unrelated
facilities. Furthermore, we currently do not carry any business disruption insurance coverage and any business disruption could cause us further harm.

Any failure by us to satisfy our end users reviews and inspections could harm our reputation and our business, financial condition, results of operations and prospects.

Several end users of our products, including several leading international pharmaceutical companies, routinely audit and inspect our
facilities, processes and practices to ensure that our services meet their internal standards and the regulatory standards applicable to them. The internal standards and regulatory standards applicable to these end users may change at any time,
which may cause us to incur additional expenditure in order to comply with these standards, and any inability to comply may result in a loss of business. Any failure to complete these audits or inspections to these end users satisfaction in
the future could significantly harm our reputation and materially and adversely affect our business, financial condition, results of operations and prospects.

If we are unsuccessful at expanding into new product lines, our business and results of operations may suffer. In addition, our business and prospects depend on our ability to successfully identify market
opportunities for new products, develop new technologies and develop and implement manufacturing processes for commercial production of the new products.

Our business model depends on our ability to successfully identify specialty chemicals with significant market opportunities for end users, develop new technologies and develop and implement manufacturing
processes for commercial production. The manufacture of new and technologically advanced products involves a complex and uncertain process requiring highly-skilled engineering and development personnel. We may be unable to produce new products in a
commercially viable manner, or at all. In addition, as specialty chemicals are characterized by

rapid technological advances, our technologies, processes and products may become uncompetitive or obsolete if our competitors adapt more quickly or cost effectively than we do to new
technologies, processes and products or changes in customer demand or requirements. In order to keep pace with technological advances and to retain our competitive position, we will need to invest substantial financial resources to improve our
technologies and production processes. If we fail to commercialize our research and development results or to improve our technologies and production processes, we may become less competitive and our results of operations may be negatively affected.
Furthermore, we cannot assure you that products, technologies and processes that we have developed will permit cost effective commercial production on a larger scale.

Our production activities are and will continue to be conducted in concentrated locations. Damage to or disruptions at our production or research and development facilities could materially and
adversely affect our business, financial condition and results of operations, especially since we do not have any business interruption insurance.

Our six operating production facilities are located in Shanghai and in Jiangsu and Zhejiang provinces, making our operations particularly vulnerable to natural and other disasters that may occur in those
provinces. Operating hazards, natural disasters or other unanticipated or catastrophic events, including power interruptions, water shortages, storms, typhoons, fires, explosions, earthquakes, terrorist attacks, wars, and labor disputes in and
around these provinces could cause damage to or destroy our facilities or equipment therein. Any of these or similar events could significantly impair our ability to operate our business, as well as delay our research and development activities and
commercial production. Our facilities and equipment are expensive and potentially difficult and time-consuming to repair or replace. Catastrophic events may also result in damage to or the destruction of inventory located in our production
facilities. In addition, we do not carry any business interruption or other insurance that would compensate us in the event of a loss of this type. The occurrence of such an event could result in substantial costs and diversion of resources, and our
business, financial condition and results of operations may be materially and adversely affected.

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

Our future success depends substantially on the continuing service of our executive officers. In particular, we depend on the services of Dr. Jianhua Yang, our founder, chairman of our board of
directors and chief executive officer, and other members of our senior management team. We do not currently maintain key employee life insurance for Dr. Yang or for any of our other employees. If one or more of our executive officers is unable
or unwilling to continue serving in his or her present position, we may not be able to find a suitable replacement. As a result, our business may be severely disrupted, and we may incur additional expenses to recruit and retain new executive
officers.

If our business grows rapidly, we may not be able to train and integrate new executive officers and operations
staff into our operations in a timely manner to cope with the growing demands of our business. In addition, if any of our executives or other key employees joins a competitor or forms a competing company, we may lose some of our customers and our
trade secrets could be compromised. Since our executive officers reside and hold most of their assets in the PRC, disputes that arise between us and our executive officers will most likely be resolved through the PRC legal system. Given the
uncertainties associated with the PRC legal system, we may be unable to enforce employment agreements in that jurisdiction. See Risks Related to Doing Business in ChinaUncertainties with respect to the PRC legal system could have a
material adverse effect on us.

Because competition for highly skilled employees is intense, we may not be able to
attract and retain the highly skilled employees we need to support our business and our expected growth.

Due to the
specialized and technical nature of our business and our reliance on proprietary manufacturing technologies, processes, patents and trade secrets, our future performance is largely dependent on the continued



17

##### Table of Contents

service of, and on our ability to attract and retain, qualified scientific, technical, marketing and support personnel. Approximately 20% of our employees are production managers, engineers,
technicians or research scientists, who have specialized experience and education. We compete with competitors and other employers, including chemical and engineering companies, for these qualified and experienced science and technology
professionals. Without sufficient numbers of skilled employees, our operations would suffer from, among other things, deteriorating production standards and decreasing capacity utilization. Competition for such skilled personnel is intense, and
replacing qualified employees is difficult. In order to effectively hire and retain a sufficient number of employees with the skills, experience and education that we require to operate and expand our business, we may be required to offer higher
compensation and other benefits, which could materially and adversely affect our business, financial condition and results of operations. If we are unable to attract, retain and motivate our scientific, technical, marketing and support personnel,
our business and prospects could be materially and adversely affected. Furthermore, we may not be able to hire sufficient numbers of skilled and experienced employees to replace those who leave, and we may be unable to redeploy and retrain our
professionals to keep pace with continuing changes in technology, evolving standards and changing customer demands, which could adversely affect our business and prospects.

Our patents and other intellectual property are important assets to us, and if we are unable to protect them, our business, financial condition and results of operations may be harmed.

Our commercial success will depend in part on our ability to obtain and enforce trade secret and patent protection for
our technologies, know-how, processes and products against third-party challenges. We will only be able to protect our technologies, processes and products from unauthorized use by third parties to the extent that we obtain valid and enforceable
intellectual property rights with respect to them. Furthermore, the degree of future protection of our proprietary rights is uncertain because legal means may only provide limited protection and may not adequately protect our exclusive proprietary
interest or permit us to gain or keep our competitive advantage.

Because most of our technologies and production methods or
processes involve unpatented, proprietary technology, processes, know-how and data, we primarily rely on trade secret protection and contractual restrictions to safeguard our interests. However, trade secrets are difficult to protect. While we use
reasonable efforts to protect our trade secrets, including requiring our employees, consultants, contractors or scientific and other advisors to enter into confidentiality agreements with us and endeavoring to induce the parties with whom we
collaborate on research projects including the end users of our products, enter into confidentiality agreements, such persons may still disclose our information to competitors in violation of their agreements. In addition, confidentiality agreements
may not be enforceable or provide an adequate remedy in the event of unauthorized use or disclosure. It may be difficult to prove or enforce a claim that a third party had illegally obtained and used our trade secrets. Our enforcement efforts would
be expensive and time-consuming and the outcome would be unpredictable. In addition, our competitors may independently develop technologies that are equivalent to our trade secrets, in which case we would not be entitled to enforce our trade secrets
and our business and prospects could be harmed.

As of the date of this annual report, we hold sixteen patents and have
nineteen patent applications pending in China. We do not hold any patents and have not submitted any applications for any patents outside of China. The process of obtaining patent protection is expensive and time-consuming, and we may not be able to
file and prosecute all necessary or desirable patent applications at reasonable costs or in a timely manner. Despite efforts to protect our proprietary rights, unauthorized parties may be able to obtain and use information that we regard as
proprietary. Changes in either the patent laws or in interpretations of patent laws in China or other countries may diminish the value of our intellectual property. Accordingly, there is a risk that we will be unable to fully enforce our patents
because we may not be able to claim protection for all the necessary components of our patents.

In addition, we have sold,
and expect to continue to sell, a substantial portion of our products outside of China, where we currently have no patent protection. In these jurisdictions, others may independently develop



18

##### Table of Contents

substantially equivalent technologies or processes, or otherwise gain access to our proprietary technologies or processes, and obtain patents for such intellectual properties, including in
countries where we sell our products, which could allow those patent holders to prevent us from selling any of our products that infringe those foreign patents in those countries.

If we are not able to protect our trade secrets and obtain and defend our patents, we will not be able to exclude competitors from
developing or producing competing products using the relevant technologies or processes, thereby adversely affecting our competitiveness which may materially and adversely affect our business, financial condition, results of operations and
prospects.

In the event that our patents are challenged, invalidated or held unenforceable or we are found to infringe
third party rights, our business, financial conditions and results of operations could be harmed.

The existence of a
patent may not necessarily protect us from competition, as any issued patent may be challenged, invalidated or held unenforceable. Competitors may successfully challenge our patents, produce similar products using processes that do not infringe our
patents or produce products in countries where we do not have patents. In addition, it is possible that competitors could, under PRC patent law, apply for and obtain a compulsory license to our patents should we refuse to grant a license under those
patents on reasonable terms. The occurrence of any of these events could hurt our competitive position and decrease our revenues from product sales.

Furthermore, the existence of a patent does not provide assurance that the production, sale or use of our products does not infringe the patent rights of another. Third parties may also have blocking
patents that could be used to prevent us from marketing products utilizing our patented technologies or processes. In addition, it takes many years for patent applications to go through the approval process and become issued patents, so it is
possible that our technologies, processes or products may infringe patents that have not yet been issued. Specifically, in China and many other jurisdictions, the term of patent protection starts from the date the application is first filed.
Therefore, our attempt to enforce any PRC patents may be defeated by third-party patents issued on a later date if the applications for those patents were filed before ours and the technologies or processes underlying such patents are the same or
substantially similar to ours. In such a case, a third party with an earlier application could force us to pay to license its patented technology, sue us for patent infringement and challenge the validity of our patents. If a third party were to sue
us for infringement, the litigation would divert substantial management time and resources, regardless of whether we were ultimately successful. Further, we could be liable for monetary damages and forced to redesign, which might prove
impracticable, impossible or too costly our technology to avoid the infringement.

In addition, as we currently have no patent
protection outside of China, if any third party successfully obtains patents in any of our markets outside of China covering technologies or processes that we use and enforce their patents against us, we may be prevented from selling products
produced from the allegedly infringing technologies in those markets, which may materially and adversely affect our business, results of operations and prospects.

If we fail to protect the intellectual property rights of our customers, we may be subject to liability for breach of contract and our reputation may be damaged.

Protection of intellectual property associated with our production, particularly the production of intermediates used in pharmaceuticals,
is critical to our customers. In manufacturing specialty chemicals used in pharmaceuticals, our customers often provide us with confidential information and intellectual property, which we have a contractual duty to protect. As a result, our success
depends in substantial part on our ability to protect the proprietary rights of our customers. Protecting the intellectual property of our customers is particularly important to us given we are located in China, and Chinese companies and the Chinese
legal system traditionally have not protected intellectual property to the same extent as their counterparts in the United States and other



19

##### Table of Contents

jurisdictions. Despite measures we take to protect our and our customers intellectual property, unauthorized parties may attempt to obtain and use information that we regard as proprietary.
Any unauthorized disclosure of our customers proprietary information could subject us to liability for breach of contract, as well as significant damage to our reputation, which could materially harm our business, financial condition, results
of operations and prospects.

Litigation involving our intellectual property rights could prove costly, and either those
costs or an adverse result in an intellectual property dispute could materially and adversely affect our business, financial condition and results of operations.

We may become a party to future litigation by third parties based on claims that our technologies, processes or products infringe the intellectual property rights of others or that we have misappropriated
the trade secrets of others. We may also initiate lawsuits to defend the ownership or inventorship of our inventions and our trade secrets. Notably, enforcement of intellectual property rights may be more difficult and/or less effective in China
when compared to other jurisdictions, such as the United States, that have a longer history of recognizing and enforcing intellectual property rights. Litigation relating to intellectual property rights is costly and diverts technical and management
personnel from their normal responsibilities. Furthermore, we may not prevail in any such litigation or proceeding. A determination in an intellectual property litigation or proceeding that results in a finding of non-infringement by others to our
intellectual property or an invalidation of our patents may result in the use by competitors of our technologies or processes and sale by competitors of products that resemble our products. In addition, a determination that we have infringed on the
intellectual property rights of another may require us to do one or more of the following:



| |  |  | pay monetary damages to the other parties to compensate for their loss, which could adversely affect our financial condition and results of operations;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | cease selling any of our infringing products, which could adversely affect our revenues;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | cease use of infringing production processes, which could make our products less competitive;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | obtain a license from the holder of the infringed intellectual property right, which might be costly or might not be available on reasonable terms, or
at all, and such license may be non-exclusive and allow one or more of our competitors to have access to the same technology licensed to us; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | redesign our technologies, processes or products to make them non-infringing, which would be costly and time-consuming, or may not be possible at all.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------

Any adverse outcome from such litigation, or the time and cost of the proceedings themselves, could
materially and adversely affect our business, financial condition and results of operations. In addition, there is a risk that some of our confidential information could be compromised by disclosure during intellectual property litigation.

Fluctuations in exchange rates could adversely affect our business and your investment.

Our sales are currently denominated in U.S. dollars, Euros and Renminbi, and our costs and expenses are primarily denominated in Renminbi.
Fluctuations in currency exchange rates could have a significant effect on our financial stability due to a mismatch among various foreign-currency-denominated assets and liabilities. Fluctuations in exchange rates, particularly among the U.S.
dollar, the Japanese Yen, the Euro and the Renminbi, affect our net profit margins and result in foreign-currency-exchange gains and losses on the corresponding assets and liabilities. For example, we incurred a total net foreign currency loss of
RMB4.8 million (US$0.7 million) in 2010 including a net foreign currency exchange loss of RMB3.2 million (US$0.5 million) recognized in our statement of income and a foreign currency translation adjustment of RMB1.6 million (USD$0.2 million) through
other comprehensive income as a component of equity. We cannot predict the impact of future exchange rate fluctuations on our results of operations and may incur material net foreign currency losses in the future.

##### Table of Contents

In addition, the change in value of the Renminbi against the U.S. dollar and other
currencies is affected by, among other things, changes in Chinas political and economic conditions. The conversion of Renminbi into foreign currencies, including U.S. dollars, is based on rates set by the Peoples Bank of China. The PRC
government allowed the Renminbi to appreciate by more than 20% against the U.S. dollar between July 2005 and July 2008. Between July 2008 and June 2010, this appreciation halted and the exchange rate between the Renminbi and the U.S. dollar remained
within a narrow band. Since June 2010, the PRC government has allowed the Renminbi to appreciate slowly against the U.S. dollar again. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between
the Renminbi against the U.S. dollar in the future. Because we rely on dividends paid to us by our operating subsidiaries, any significant revaluation of the Renminbi may have a material adverse effect on the value of, and any dividends payable on,
our ADSs in foreign currency terms. For example, to the extent that we need to convert U.S. dollars we receive from our initial public offering into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an
adverse effect on the Renminbi amount we would receive from the conversion. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business
purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount available to us. Consequently, appreciation or depreciation in the value of the Renminbi relative to the U.S. dollar would affect
our financial results reported in U.S. dollar terms without giving effect to any underlying change in our business or results of operations.

In addition, an appreciation in the value of the Renminbi against foreign currencies could make our products more expensive for our international customers, which could adversely affect our international
sales. Appreciation of the Renminbi could also reduce the competitiveness of the products of our PRC customers in the international market, which may potentially lead to a reduction in their orders from us and negatively affect our sales and results
of operations. Furthermore, many of our competitors are foreign companies that could benefit from such currency appreciation, making it more difficult for us to compete against these companies. On the other hand, depreciation in the value of the
Renminbi against foreign currencies could increase the costs of the raw materials we purchase from foreign suppliers.

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

As part of our plan to sustain business growth, we intend to make strategic acquisitions and investments and to establish and maintain joint ventures and strategic relationships with third parties. We may
engage in such activities to gain expertise in performing certain process design and development, production and logistical activities, access to raw materials, equipment and facilities or support our marketing and sales activities. In addition, we
may enter into strategic relationships with third parties to gain access to capital or funding for research and development programs, process development programs and commercialization activities, or to reduce the risk of developing and scaling-up
for commercial production of pipeline products.

Our strategic acquisitions, investments, joint ventures and strategic
relationships with third parties may not be beneficial for our business. Furthermore, exploration into these transactions, whether or not actually consummated, could require us to incur significant expenses and could divert significant management
time and attention from our existing business operations, which could harm the effective management of our business. This could have a material adverse effect on our market penetration, revenues growth and results of operations.

In addition, strategic acquisitions, investments and relationships with third parties could subject us to a number of risks, including:



| |  |  | our inability to integrate new operations, products, personnel, services or technologies;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | unforeseen or hidden liabilities, including exposure to lawsuits associated with newly acquired companies;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | the diversion of resources from our existing businesses;
| | - |  | --------------------------------------------------------

##### Table of Contents

| |  |  | disagreement with joint venture or strategic relationship partners;
| | - |  | -------------------------------------------------------------------



| |  |  | our inability to generate sufficient revenues to offset the costs and expenses of strategic acquisitions, investments, joint venture formations, or
other strategic relationships; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | potential loss of, or harm to, employees or customer relationships.
| | - |  | -------------------------------------------------------------------

Any one or more of these events could impair our ability to manage our business, result in our failure to derive the intended benefits of
the strategic acquisitions, investments, joint ventures or strategic relationships, result in us being unable to recover our investment in such initiatives or otherwise have a material adverse effect on our business, financial condition and results
of operations.

Our future liquidity needs are uncertain and we may need to raise additional funds in the future.

We may need to raise additional funds within the foreseeable future if our expenditures exceed our current
expectations. This could occur for a number of reasons, including, for example, if we decide to devote a significant amount of financial resources to the research and development of projects that we believe to have significant commercial potential.
Our ability to raise additional funds in the future is subject to a variety of uncertainties, including:



| |  |  | our future financial condition, results of operations and cash flows;
| | - |  | ---------------------------------------------------------------------



| |  |  | general market conditions for capital-raising activities by early stage China-based companies; and
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | economic, political and other conditions in China and elsewhere.
| | - |  | ----------------------------------------------------------------

If our revenues are not sufficient to meet our operational needs and capital requirements or if we have future liquidity needs or other
business reasons, we may need (or we may elect) to sell additional equity or debt securities or borrow funds to raise capital. The sale of additional equity or equity-linked securities could result in additional dilution to our shareholders. The
incurrence of additional debt would result in increased debt service obligations and could result in operating and financing covenants that would restrict our operations or our ability to pay dividends.

Our largest shareholder, who holds a significant portion of our outstanding equity, may have substantial influence over our company
and his interests may not be aligned with the interests of our other shareholders.

Dr. Jianhua Yang, our founder,
chief executive officer and chairman of our board of directors, beneficially owns approximately 55.8% of our outstanding share capital as of the date of this annual report. As such, Dr. Jianhua Yang has substantial influence over our business,
including decisions regarding mergers, consolidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. This concentration of ownership may discourage, delay or prevent a change in
control of our company, which could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and might negatively impact the price of our ADSs. These actions may be taken even if they are
opposed by our other shareholders.

Our grant of employee share options, restricted shares or other share-based
compensation and any future such grants could have an adverse effect on our net income.

We adopted our share incentive
plan in 2008 and modified it in 2010. We have granted share options under this share incentive plan. We recognize share-based compensation as compensation expense in the statement of operations based on the fair value of equity awards on the date of
the grant, with the compensation expense recognized over the period in which the recipient is required to provide service in exchange for the equity award. We adopt a fair value-based method for measuring the compensation expense related to
share-based compensation. The additional expenses associated with share-based compensation may reduce the attractiveness of issuing share options or restricted shares under our share incentive plan. However, if we do not grant share



22

##### Table of Contents

options or restricted shares, or reduce the number of share options or restricted shares that we grant, we may not be able to attract and retain key personnel. If we grant more share options or
restricted shares to attract and retain key personnel, the expenses associated with share-based compensation may adversely affect our net income.

Current or worsening economic conditions could adversely impact our business.

Since early 2008, there has been a significant deterioration in the U.S. and global economy and thus liquidity has contracted significantly. In light of the recent European debt crisis, the global economy
is still uncertain and may continue to deteriorate in the future. There were, and could be in the future, domino effects from such turmoil on our business. Like other players in the market, we face risks attendant to changes in consumer demand for
products that incorporate our specialty chemicals, economic environments, changes in interest rates and instability in securities markets around the world, among other factors. In particular, the worsening economic climate had resulted in decreased
industrial output and decreased consumer demand for products including consumer electronics, which beginning in early 2009 had resulted in decreased demand for our specialty chemicals used in the manufacture of TFT-LCDs in 2009. In addition, we had
been unfavorably impacted by the decreased demand in the global agrochemical market beginning in the second half of 2009. In 2010, we saw a strong recovery in demand for our specialty chemicals used in the electronics market and some mild recovery
in demand for our specialty chemicals used in the agrochemical market. But we cannot assure you that these resumed growths will continue in the near future as there are many other contingencies and the global economy may further deteriorate. Any
systemic economic or financial crisis could cause revenues for our industry as a whole to decline dramatically and could materially and adversely affect our results of operations.

Climate change, other environmental concerns and green initiatives present commercial challenges, economic risks and physical risks
that could harm our results of operations or affect the manner in which we conduct our business

Increasing climate
change and environmental concerns could affect the results of our operations if any of our customers would request us to exceed any standards set for environmentally compliant products. If we are unable to offer such products, we may lose market
share to our competitors.

Further, energy costs in general could increase significantly due to climate change regulations.
Therefore, our energy costs may increase significantly if utility or power companies pass on their costs, fully or partially, such as those associated with carbon taxes, emission cap and carbon credit trading programs.

In addition, more frequent droughts and floods, extreme weather conditions and rising sea levels could occur due to climate change. The
impact of such changes could be significant. For instance, our sales to the agrochemical end-market was negatively impacted by the bad weather pattern in the second half of 2009. For example, transportation suspension caused by extreme weather
conditions could harm the delivery of our supplies and the distribution of our products. We cannot predict the economic impact, if any, of disasters or climate change.

Risks Related to Doing Business in China

Substantially all of our
operations are conducted in China. Accordingly, to a significant extent, our business, financial condition, results of operations and prospects are subject, to economic, political and legal developments in China.

We face risks related to natural disasters and health epidemics in China, which could have a material adverse effect on our
business and results of operations.

Our business could be materially and adversely affected by natural disasters or
the outbreak of health epidemics in China. For example, in May 2008, Sichuan Province suffered a strong earthquake measuring



23

##### Table of Contents

approximately 8.0 on the Richter scale that caused widespread damage and casualties. In addition, in the last decade, the PRC has suffered health epidemics related to the outbreak of avian
influenza and severe acute respiratory syndrome, or SARS. In April 2009, an outbreak of the H1N1 virus, also commonly referred to as swine flu, occurred in Mexico and has spread to other countries. Cases of swine flu have been reported
in Hong Kong and mainland China. If the outbreak of swine flu were to become widespread in China or increase in severity, it could have an adverse effect on economic activity in China, and our business and operations could be adversely affected. Any
future natural disasters or health epidemics in the PRC could also have a material adverse effect on our business and results of operations.

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

The PRC legal system is a civil law system based on written statutes. Unlike common law systems, prior court decisions may be cited for reference but have limited precedential value. In 1979, the PRC
government began to promulgate a comprehensive system of laws and regulations governing economic matters in general. The overall effect of legislation since then has been to significantly enhance the protections afforded to various forms of foreign
investments in China. We conduct the majority of our business through our subsidiaries established in China. These subsidiaries are generally subject to laws and regulations applicable to foreign investment in China and, in particular, laws
applicable to wholly foreign-owned enterprises. 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 involves uncertainties, which may limit legal protections available to us. In addition, some regulatory requirements issued by certain PRC government authorities may not be consistently applied by
other government authorities (including local government authorities), thus making strict compliance with all regulatory requirements impractical, or in some circumstances, impossible. For example, we may have to resort to administrative and court
proceedings to enforce the legal protection that we enjoy either by law or contract. However, since PRC administrative and court authorities have significant discretion in interpreting and implementing statutory and contractual terms, it may be more
difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy than in more developed legal systems. These uncertainties may impede our ability to enforce the contracts we have entered into with
our business partners, customers and suppliers. By way of further example, although required by PRC law, many foreign-invested enterprises, including our PRC subsidiaries, have not historically obtained approvals from the National Development and
Reform Commission, or NDRC, or its counterparts before receiving the approval from the Ministry of Commerce or its counterparts for their establishment. However, the legal consequence for failure to obtain the NDRC approval by those foreign-invested
enterprises, including our PRC subsidiaries, is not prescribed under the current PRC law. In addition, such uncertainties, including the inability to enforce our contracts, together with any development or interpretation of PRC law that is adverse
to us, could materially and adversely affect our business and operations. Furthermore, intellectual property rights and confidentiality protections in China may not be as effective as in the United States or other countries. Accordingly, we cannot
predict the effect of future developments in the PRC legal system, including the promulgation of new laws, changes to existing laws or the interpretation or enforcement thereof, or the preemption of local regulations by national laws. These
uncertainties could limit the legal protections available to us and other foreign investors, including you. In addition, any litigation in China may be protracted and result in substantial costs and diversion of our resources and management
attention.

Unauthorized use of our intellectual property by third parties and the expenses we might need to incur in
protecting our intellectual property rights, may adversely affect our business.

Our patents, trade secrets and other
intellectual property are important to our success. In particular, our proprietary manufacturing processes, many of which we protect as trade secrets, are important to our business and we believe are one of our competitive advantages. Unauthorized
use of any of our intellectual property may adversely affect our business and reputation. We rely on patent law, trade secret protection and confidentiality agreements with our employees, clients, business partners and others to protect our
intellectual property rights. Nevertheless, it may be possible for third parties to obtain and use our intellectual property without authorization.



24

##### Table of Contents

The unauthorized use of intellectual property is common and widespread in China and enforcement of intellectual property rights by Chinese regulatory agencies is inconsistent. Moreover,
litigation may be necessary in the future to enforce our intellectual property rights. Future litigation could result in substantial costs and diversion of our managements attention and resources, and could disrupt our business, as well as
have a material adverse effect on our financial condition and results of operations. Given the relative unpredictability of Chinas legal system and potential difficulties enforcing a court judgment in China, we may be unable to halt the
unauthorized use of our intellectual property through litigation, which could adversely affect our competitive position, our ability to attract customers, and our results of operations.

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 materially and adversely affect our results of operations and competitive position.

Substantially all of our business operations are conducted in China with some of our sales made 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 economies of most developed countries in many respects, including:



| |  |  | the degree of government involvement;
| | - |  | -------------------------------------



| |  |  | the level of development;
| | - |  | -------------------------



| |  |  | the growth rate;
| | - |  | ----------------



| |  |  | the control of foreign exchange;
| | - |  | --------------------------------



| |  |  | access to financing; and
| | - |  | ------------------------



| |  |  | the allocation of resources.
| | - |  | ----------------------------

While the Chinese economy has grown significantly in the past 30 years, the growth has been uneven, both geographically and among various sectors of the economy. The PRC government has implemented various
measures to encourage, but also to control 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. For example, our financial condition and results
of operations may be adversely affected by government control over capital investments or changes in tax regulations that are applicable to us.

The Chinese economy has been transitioning from a planned economy to a more market-oriented economy since the late 1970s. Although in recent years the PRC government has implemented measures emphasizing
the utilization of market forces for economic reform, the reduction of state ownership of productive assets and the establishment of sound corporate governance in business enterprises, a substantial portion of the productive assets in China is still
owned by the PRC government. The continued control of these assets and other aspects of the national economy by the PRC government could materially and adversely affect our business. The PRC government also exercises significant control over
Chinas economic growth through the allocation of resources, controlling payment of foreign-currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies. Since late 2003,
the PRC government implemented a number of measures, such as raising bank reserves against deposit rates to place additional limitations on the ability of commercial banks to make loans and raise interest rates, in order to control the pace of
economic growth. These actions, as well as future actions and policies of the PRC government, could cause decreased economic activity in China and could materially affect our business, liquidity, access to capital, results of operations and
financial condition.

Chinas social and political conditions are also not as stable as those of the United States and
other developed countries. Any sudden changes to Chinas political system or the occurrence of widespread social unrest could have negative effects on our business and results of operations. In addition, China has contentious



25

##### Table of Contents

relations with some of its neighbors, most notably Taiwan. A significant further deterioration in such relations could have negative effects on the Chinese economy and lead to changes in
governmental policies that would be adverse to our business interests.

We rely on dividends paid by our consolidated
subsidiaries for our cash needs, and any limitation on the ability of our subsidiaries to make payments to us could have a material adverse effect on our ability to conduct our business.

We conduct all of our business through our consolidated subsidiaries incorporated in China. We rely on dividends paid by these
consolidated subsidiaries for our cash needs, including the funds necessary to pay any dividends and other cash distributions to our shareholders, to service any debt we may incur and to pay our operating expenses. The payment of dividends by
entities established in China is subject to limitations. Regulations in China currently permit payment of dividends only out of accumulated profits as determined in accordance with accounting standards and regulations in China. Each of our PRC
subsidiaries, including wholly foreign-owned enterprises, or WFOEs, and joint venture enterprises is also required to set aside at least 10% of its after-tax profit based on PRC accounting standards each year to its general reserves or statutory
capital reserve fund until the aggregate amount of such reserves reaches 50% of its respective registered capital. Our statutory reserves are not distributable as loans, advances or cash dividends. In addition, if any of our PRC subsidiaries 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. As of December 31, 2010, our PRC subsidiaries had allocated RMB85.8 million (US$13.0 million)
to these reserves. Any limitations on the ability of our PRC subsidiaries to transfer funds to us could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our business, pay dividends and
otherwise fund and conduct our business.

In addition, the newly enacted PRC Enterprise Income Tax Law, or the EIT Law, and
its relevant regulations also impose a withholding tax at 10%, unless reduced by a tax treaty, for dividend distributions out of earnings accumulated beginning on January 1, 2008. Undistributed earnings generated prior to January 1, 2008
are exempt from such withholding tax. Under the Arrangement between the PRC and the Hong Kong Special Administrative Region on the Avoidance of Double Taxation and Prevention of Fiscal Evasion, or the China-Hong Kong tax arrangement, a qualified
Hong Kong tax resident which is the beneficial owner and holds 25% or more of the equity interest in a PRC-resident enterprise is entitled to a reduced withholding rate of 5%. We are actively monitoring the withholding tax and are
evaluating appropriate organizational changes to minimize the corresponding tax impact.

PRC regulation of loans and
direct investment by offshore holding companies to PRC entities may delay or prevent us from making loans or additional capital contributions to our PRC operating subsidiaries and affiliated entities, which could materially and adversely affect our
liquidity and our ability to fund and expand our business.

As an offshore holding company of our PRC operating
subsidiaries and affiliates, we may make loans to our PRC subsidiaries and consolidated PRC affiliated entities, or we may make additional capital contributions to our PRC subsidiaries. Any loans to our PRC subsidiaries are subject to PRC
regulations and approvals. For example, loans by us to our wholly owned subsidiaries in China that are foreign-invested enterprises to finance their activities cannot exceed statutory limits and must be registered with the State Administration of
Foreign Exchange in China, or the SAFE, or its local branch.

We may also decide to finance our wholly owned subsidiaries by
means of capital contributions. These capital contributions must be approved by the Ministry of Commerce in China or its local counterpart. We cannot assure you that we will be able to complete these government registrations or obtain the government
approvals on a timely basis, if at all, with respect to future loans or capital contributions by us to our subsidiaries or any of their respective subsidiaries. If we fail to complete these registrations or obtain the approvals, our ability to
capitalize our PRC operations may be negatively affected, which could adversely and materially affect our liquidity and our ability to fund and expand our business.

The approval of the Chinese Securities Regulatory Commission, or the CSRC, might have
been required in connection with our initial public offering, and, if required, we could be subject to sanction, fines and other penalties.

On August 8, 2006, six PRC regulatory agencies, including the CSRC, promulgated the Provisions Regarding Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the new
M&A rule, which took effect on September 8, 2006, to more effectively regulate foreign investment in PRC domestic enterprises. The new M&A rule also contains a provision requiring offshore special purpose vehicles, or SPVs, formed for
overseas listing purposes and controlled by PRC individuals to obtain the approval of the CSRC prior to publicly listing their securities on an overseas stock exchange.

The application of this new M&A rule is currently unclear. However, our PRC counsel, Jin Mao PRC Lawyers, has advised us that based on its understanding of the current PRC laws, rules and regulations
and the new M&A rule, the new M&A rule does not require that we obtain prior CSRC approval for the listing and trading of our ADSs on the NYSE, because our acquisition of the equity interest in our PRC subsidiaries is not subject to the new
M&A rule due to the fact that each of them was already a foreign-invested enterprise before September 8, 2006, the effective date of the new M&A rule.

Jin Mao PRC Lawyers has further advised us that their opinions summarized above are subject to the timing and content of any new laws, rules and regulations or clear implementations and interpretations
from the CSRC in any form relating to the new M&A rule.

However, if the CSRC or another PRC regulatory agency
subsequently determines CSRC prior approval was required, we may face regulatory actions or other sanctions from the CSRC or other PRC regulatory agencies. These regulatory agencies may impose fines and penalties on our operations, limit our
operating privileges, delay or restrict the repatriation of the proceeds from the initial public offering of our ADSs into China or payment or distribution of dividends by our PRC subsidiaries, or take other actions that could have a material
adverse effect on our business, financial condition, results of operations, reputation and prospects, as well as the trading price of our ADSs. Also, if the CSRC later requires that we obtain its approval, we may be unable to obtain a waiver of the
CSRC approval requirements, if and when procedures are established to obtain such a waiver. Any uncertainties or negative publicity regarding this CSRC approval requirement could have a material adverse effect on the trading price of our ADSs.

We cannot predict when the CSRC may promulgate additional implementing rules or other guidance, if at all. Moreover,
implementing rules or guidance, to the extent issued, may fail to resolve current ambiguities under this new PRC regulation. Uncertainties and/or negative publicity regarding this new PRC regulation could have a material adverse effect on the
trading price of our ADSs.

The new M&A rule establishes more complex procedures for some acquisitions of Chinese
companies by foreign investors, which could make it more difficult for us to pursue growth through acquisitions in China.

The new M&A rule establishes additional procedures and requirements that could make some acquisitions of Chinese companies by foreign investors more time-consuming and complex, including requirements
in some instances that the Ministry of Commerce be notified in advance of any change-of-control transaction in which a foreign investor takes control of a Chinese domestic enterprise. In the future, we may grow our business in part by acquiring
complementary businesses, although we do not have any plans to do so at this time. Complying with the requirements of the new M&A rule to complete such transactions could be time-consuming, and any required approval processes, including
obtaining approval from the Ministry of Commerce, may delay or inhibit our ability to complete such transactions, which could affect our ability to expand our business or maintain our market share.

Recent PRC regulations relating to the establishment of offshore special purpose
companies by PRC residents may subject our PRC resident shareholders or our PRC subsidiaries to penalties, limit our ability to distribute capital to our PRC subsidiaries, limit our PRC subsidiaries ability to distribute funds to us, or
otherwise adversely affect us.

The SAFE issued a public notice in October 2005, or the SAFE Circular No. 75,
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 with assets or equities of PRC companies, referred to in the SAFE Circular
No. 75 as SPVs. PRC residents who are shareholders of SPVs established before November 1, 2005 were required to register with the local SAFE branch before March 31, 2006. Further, PRC residents are required to file amendments to their
registrations with the local SAFE branch if their SPVs undergo a material event involving changes in capital, such as changes in share capital, mergers and acquisitions, share transfers or exchanges, spin-off transactions or long-term equity or debt
investments. On May 29, 2007, the SAFE issued guidance to its local branches for the implementation of the SAFE Circular No. 75. This guidance standardizes more specific and stringent supervision on the registration requirement relating to
the SAFE Circular No. 75 and further requests PRC residents holding any equity interests or options in SPVs, directly or indirectly, controlling or nominal, to make overseas investment foreign exchange registration with the SAFE. Our current
beneficial owners have made the registration successfully. However, any failure by beneficial owners of our ordinary shares to amend their registration or the failure of future beneficial owners of our company who are PRC residents to comply with
the registration procedures set forth in the SAFE Circular No. 75 could subject such beneficial owners and our PRC subsidiaries to fines and legal sanctions. See Item 4. Information on the CompanyB. Business
OverviewRegulationForeign Exchange Regulation.

Under the Implementation Rules of the Administration Measure
for Individual Foreign Exchange, or the Individual Foreign Exchange Rule, and an implementation guidance on the rule, issued in January and March 2007, respectively, by the SAFE, PRC citizens who are granted share options by an overseas
publicly-listed company are required, through a PRC agent who may be the PRC subsidiary of such overseas publicly-listed company, to register with the SAFE and complete certain other procedures related to the share options. We and our PRC citizen
employees who have been granted share options, or PRC optionees, are subject to these regulations as our company is now an overseas publicly-listed company. If we or our PRC optionees fail to comply with these regulations, we or our PRC optionees
may be subject to fines and legal sanctions. However, as these rules were only recently promulgated, it is currently unclear as to how they will be interpreted and implemented. See Item 4. Information on the CompanyB. Business
OverviewRegulationRegulations Relating to Employee Share Options.

Dividends we receive from our
operating subsidiaries located in the PRC may be subject to PRC withholding tax.

The EIT Law and the implementation
regulations for the EIT Law issued by the PRC State Council, became effective as of January 1, 2008. The EIT Law provides that a maximum income tax rate of 20% may be applicable to dividends payable to non-PRC investors that are
non-resident enterprises, to the extent such dividends are derived from sources within the PRC, and the State Council has reduced such rate to 10% through the implementation regulations. According to the China- Hong Kong tax arrangement,
dividends paid to enterprises incorporated in Hong Kong are subject to a withholding tax of 5%. We are a Cayman Islands holding company and substantially all of our income may be derived from dividends we receive from our operating subsidiaries
located in the PRC. Thus, dividends paid to us through our Hong Kong subsidiary by our subsidiaries in China may be subject to the 5% income tax if we are considered as a non-resident enterprise under the EIT Law. If we are required
under the EIT Law to pay income tax for any dividends we receive from our subsidiaries, it will materially and adversely affect the amount of dividends, if any, we may pay to our shareholders and ADS holders.

We may be classified as a resident enterprise for PRC enterprise income
tax purposes, which could result in unfavorable tax consequences to us and our non-PRC shareholders.

The Enterprise
Income Tax Law provides that enterprises established outside of China whose de facto management bodies are located in China are considered resident enterprises and are generally subject to the uniform 25% enterprise income
tax rate on their worldwide income. In addition, a circular issued by the State Administration of Taxation regarding the standards used to classify certain Chinese-invested enterprises controlled by Chinese enterprises or Chinese group enterprises
and established outside of China as resident enterprises clarified that dividends and other income paid by such resident enterprises will be considered to be PRC source income, subject to PRC withholding tax, currently at a
rate of 10%, when recognized by non-PRC shareholders. This recent circular also subjects such resident enterprises to various reporting requirements with the PRC tax authorities. Under the implementation regulations to the enterprise
income tax, a de facto management body is defined as a body that has material and overall management and control over the manufacturing and business operations, personnel and human resources, finances and treasury, and acquisition and
disposition of properties and other assets of an enterprise. In addition, the recent circular mentioned above details that certain Chinese-invested enterprises controlled by Chinese enterprises or Chinese group enterprises will be classified as
resident enterprises if the following are located or resident in China: senior management personnel and departments that are responsible for daily production, operation and management; financial and personnel decision making bodies; key
properties, accounting books, company seal, and minutes of board meetings and shareholders meetings; and half or more of the directors with voting rights or senior management. If the PRC tax authorities determine that we are a resident
enterprise, we may be subject to enterprise income tax at a rate of 25% on our worldwide income and dividends paid by us to our non-PRC shareholders as well as capital gains recognized by them with respect to the sale of our stock may be
subject to a PRC withholding tax. This will have an impact on our effective tax rate, a material adverse effect on our net income and results of operations, and may require us to withhold tax on our non-PRC shareholders.

Dividends payable by us to our foreign investors and gain on the sale of our ADSs or ordinary shares may become subject to taxes
under PRC tax laws.

Under the EIT Law and implementation regulations issued by the State Council, PRC income tax at
the rate of 10% is applicable to dividends payable to investors that are non-resident enterprises, which do not have an establishment or place of business in the PRC, or which have such establishment or place of business but the relevant
income is not effectively connected with the establishment or place of business, to the extent such dividends have their sources within the PRC. Similarly, any gain realized on the transfer of ADSs or shares by such investors is also subject to 10%
PRC income tax if such gain is regarded as income derived from sources within the PRC. According to the China-Hong Kong tax arrangement, dividends paid to enterprises incorporated in Hong Kong are subject to a withholding tax of 5%. If we are
considered a PRC resident enterprise, it is unclear whether dividends we pay with respect to our ordinary shares or ADSs, or the gain you may realize from the transfer of our ordinary shares or ADSs, would be treated as income derived
from sources within the PRC and be subject to PRC tax. If we are required under the EIT Law to withhold PRC income tax on dividends payable to our non-PRC investors that are non-resident enterprises, or if you are required to pay PRC
income tax on the transfer of our ordinary shares or ADSs, the value of your investment in our ordinary shares or ADSs may be materially and adversely affected.

Governmental control of currency conversion may limit our ability to receive dividends from our subsidiaries in China.

Certain portions of our revenues and expenses are denominated in Renminbi. If our revenues denominated in Renminbi increase or expenses
denominated in Renminbi decrease in the future, we may need to convert a portion of our revenues into other currencies to meet our foreign currency obligations, including, among others, debt service or payment of dividends declared, if any, in
respect of our ordinary shares. Under Chinas existing foreign exchange regulations, our PRC subsidiaries are allowed to pay dividends in foreign currencies, without



29



---

##### Table of Contents

prior approval from the SAFE, by complying with certain procedural requirements. However, the PRC government may take further measures in the future to restrict access to foreign currencies for
current account transactions.

Foreign exchange transactions by our subsidiaries under capital accounts continue to be subject
to significant foreign exchange controls and require the approval of, or registration with, PRC governmental authorities. In particular, if one subsidiary borrows foreign currency loans from us or other foreign lenders, these loans must be
registered with SAFE or its local counterparts, and if we finance such subsidiary by means of additional capital contributions, these capital contributions must be approved by certain government authorities including the Ministry of Commerce or its
local counterparts. These limitations could affect the ability of our subsidiaries to obtain foreign exchange through debt or equity financing.

New labor laws in the PRC may adversely affect our results of operations.

On June 29, 2007, the PRC government promulgated a new labor law, namely, the Labor Contract Law of the PRC, or the New Labor Contract Law, which became effective on January 1, 2008. The New
Labor Contract Law imposes greater liabilities on employers and significantly affects the cost of an employers decision to reduce its workforce. Further, it requires certain terminations be based upon seniority and not merit. In the event we
decide to significantly change or decrease our workforce, the New Labor Contract Law could adversely affect our ability to enact such changes in a manner that is most advantageous to our business or in a timely and cost-effective manner, thus
materially and adversely affecting our financial condition and results of operations.

If we are found to have failed to
comply with applicable laws, we may incur additional expenditures or be subject to significant fines and penalties.

Our operations are subject to PRC laws and regulations applicable to us. However, many PRC laws and regulations are uncertain in their
scope, and the implementation of such laws and regulations in different localities could have significant differences. In certain instances, local implementation rules and the actual implementation are not necessarily consistent with the regulations
at the national level. Although we strive to comply with all the applicable PRC laws and regulations, we cannot assure you that the relevant PRC government authorities will not later determine that we have not been in compliance with certain laws or
regulations. In particular, there is a PRC regulation requiring all employees to make contributions to a housing provident fund based on their salary level and their employers to match such contributions. However, some employees are reluctant to
make such contributions as they do not perceive such contribution will benefit them, and this regulation generally has not been rigorously enforced. We have allowed our employees to make contributions on a voluntary basis and then match their
contributions. However, we cannot assure you that in the future the PRC government will not start to enforce this regulation more rigorously. Although there are no material penalties stipulated in this regulation, if we are found to not be in
compliance, we may be required to bring current any past deficiencies, which could adversely affect our financial condition and results of operations.

The continuation or worsening of recent trends toward price inflation in China could erode some of the advantages of operating in a relatively low-cost jurisdiction such as China, which could
negatively affect our competitive advantages and our results of operations.

In recent years, inflation in China has
increased. According to the China Statistics Bureau, consumer price inflation in China was 5.9%, -0.7% and 3.3% in 2008, 2009 and 2010, respectively. Because we purchase raw materials from suppliers in China, this price inflation has increased the
costs of the raw materials we must purchase for production. This trend risks counteracting the competitive advantage we enjoy as a result of the relatively lower production costs we incur from operating in China. If inflationary trends continue in
China, China could lose its competitive advantage as a low-cost manufacturing venue, including with respect to our products, which could in turn lessen any competitive and reputational advantages we gain through China-based manufacturing.
Accordingly, continuing or increasing inflation in China may weaken our competitiveness in our markets and have a material adverse effect on our business and results of operations.

Risks Related to Ownership of Our Shares or ADSs

The market price for our ADSs may be volatile, which could result in substantial losses to you.

The market price for our ADSs is likely to be highly volatile and subject to wide fluctuations in response to factors, many of which are
beyond our control and which may occur regardless of our actual operating performance, including the following:



| |  |  | announcements of technological or competitive developments;
| | - |  | -----------------------------------------------------------



| |  |  | regulatory developments in China affecting us, our customers or our competitors;
| | - |  | --------------------------------------------------------------------------------



| |  |  | announcements regarding patent or other intellectual property litigation or the issuance of patents to us or our competitors or updates with respect to
the enforceability of patents or other intellectual property rights generally in China or internationally;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | actual or anticipated fluctuations in our quarterly operating results;
| | - |  | ----------------------------------------------------------------------



| |  |  | changes in financial estimates by securities research analysts;
| | - |  | ---------------------------------------------------------------



| |  |  | changes in the economic performance or market valuations of other specialty chemicals companies;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | addition or departure of our executive officers and key research personnel;
| | - |  | ---------------------------------------------------------------------------



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



| |  |  | sales or perceived sales of additional ordinary shares or ADSs; and
| | - |  | -------------------------------------------------------------------



| |  |  | Our board of directors decision to implement new share repurchase programs and to change dividend policies.
| | - |  | ------------------------------------------------------------------------------------------------------------

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. Any of these factors could result in large and sudden changes in the volume and trading price of our ADSs and could cause holders of our ADSs to incur substantial losses. In the past, following
periods of volatility in the market price of a companys securities, shareholders have often instituted securities class action litigation against that company. If we were involved in a class action suit or other securities litigation, it would
divert the attention of our senior management, require us to incur significant expense and, whether or not adversely determined, could have a material adverse effect on our business, financial condition, results of operations and prospects.

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

Sales of our ADSs or common shares in the public market, or the perception that
these sales could occur, could cause the market price of our ADSs to decline. As of December 31, 2010, we had 2,163,190,740 ordinary shares outstanding, including 545,746,140 ordinary shares represented by 9,095,769 ADSs. Sales of our ordinary
shares or ADSs held by our significant shareholders or any other shareholder, or the availability of these securities for future sale, may have a negative effect on the market price of our ADSs.

In addition, certain holders of our ordinary shares or their transferees and assignees will have the right to cause us to register the
sale of their shares under the Securities Act upon the occurrence of certain circumstances. 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.

Our articles of association contain anti-takeover provisions that could discourage a third party from acquiring us, which could limit our shareholders opportunity to sell their shares,
including ordinary shares represented by our ADSs, at a premium.

Our memorandum and articles of association contain
provisions which limit the ability of others to acquire control of our company or cause us to engage in change-of-control transactions. These provisions could have the



31



---

##### Table of Contents

effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our company
in a tender offer or similar transaction. For example, our board of directors has the authority, without further action by our shareholders, to issue preferred shares. These preferred shares may have better voting rights than our ordinary shares, in
the form of ADSs or otherwise, and could be issued quickly with terms calculated to delay or prevent a change in control of our company or make removal of management more difficult. If our board of directors decides to issue preferred shares, the
price of our ADSs may fall and the voting rights of the holders of our ordinary shares and ADSs may be diluted.

Certain
actions require the approval of a supermajority of at least two-thirds of the members of our board of directors which, among other things, would allow our non-independent directors to block a variety of actions or transactions, such as a merger,
asset sale or other change of control, even if all of our independent directors unanimously voted in favor of such action, thereby further depriving our shareholders of an opportunity to sell their shares at a premium.

Holders of ADSs have fewer rights than shareholders and must act through the depositary to exercise their rights.

Holders of ADSs do not have the same rights of our shareholders and may only exercise voting rights with respect to
the underlying ordinary shares in accordance with the provisions of the deposit agreement. Under our memorandum and articles of association, the minimum notice period required to convene a general meeting is twenty-one days. When a general meeting
is convened, you may not receive sufficient notice of a shareholders meeting to permit you to withdraw your ordinary shares to allow you to cast your vote with respect to any specific matter. In addition, the depositary and its agents may not
be able to send voting instructions to you or carry out your voting instructions in a timely manner. We will make all reasonable efforts to cause the depositary to extend voting rights to you in a timely manner, but we cannot assure you that you
will receive the voting materials in time to ensure that you can instruct the depositary to vote your ADSs. Furthermore, the depositary and its agents will not be responsible for any failure to carry out any instructions to vote, for the manner in
which any vote is cast or for the effect of any such vote. As a result, you may not be able to exercise your right to vote and you may lack recourse if your ADSs are not voted as you requested. In addition, in your capacity as an ADS holder, you
will not be able to call a shareholders meeting.

You may be subject to limitations on transfers 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 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. Also, under the deposit agreement, the depositary bank will not make rights available to you unless the distribution to ADS holders of both the rights and any related securities are either
registered under the Securities Act or exempted 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 cause such a registration statement to be
declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

##### Table of Contents

In addition, 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 not lawful or reasonably practicable 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.

We are a Cayman Islands company and, because judicial precedent regarding the rights of shareholders is more limited under Cayman
Islands law than that under U.S. law, you may have less protection for your shareholder rights than you would under U.S. law.

Our corporate affairs are governed by our memorandum and articles of association, as amended and restated from time to time, the Cayman Islands Companies Law (as amended) and the common law of the Cayman
Islands. The rights of shareholders to take action against the directors, actions by noncontrolling 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 precedent in some jurisdictions in the United
States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. In addition, some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the
Cayman Islands.

As a result of all of the above, public shareholders may have more difficulty in protecting their interests
in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as shareholders of a U.S. public company.

You may have difficulty enforcing judgments obtained against us.

We
are a Cayman Islands company and substantially all of our assets are located outside of the United States. Substantially all of our current operations are conducted in the PRC. In addition, many of our directors and officers are nationals and
residents of countries other than the United States. As a result, it may be difficult for you to effect service of process within the United States upon these persons. It may also be difficult for you to enforce in U.S. courts judgments obtained in
U.S. courts based on the civil liability provisions of the U.S. federal securities laws against us and our officers and directors, many of whom are not residents in the United States and the substantial majority of whose assets are located outside
of the United States. In addition, there is uncertainty as to whether the courts of the Cayman Islands or the PRC would recognize or enforce judgments of U.S. courts against us or such persons predicated upon the civil liability provisions of the
securities laws of the United States or any state and it is uncertain whether such Cayman Islands or PRC courts would be competent to hear original actions brought in the Cayman Islands or the PRC against us or such persons predicated upon the
securities laws of the United States or any state.

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 our financial
statements, relevant market data and the projected composition of our income and valuation of our assets, including goodwill, we do not believe that we were a passive foreign investment company, or PFIC, for 2010, and we do not expect to be a PFIC
in 2011 or to become one in the foreseeable future, although there can be no assurance in this regard. If, however, we become a PFIC, such characterization could result in adverse U.S. tax consequences to you if you are a U.S. investor. For example,
if we become a PFIC, our U.S. investors will become subject to increased tax liabilities under U.S. tax laws and regulations and



33



---

##### Table of Contents

will become subject to burdensome reporting requirements. The determination of whether or not we are a PFIC is made on an annual basis and depends on the composition of our income and assets from
time to time. Specifically, we will be classified as a PFIC for U.S. tax purposes if either: (i) 75% or more of our gross income in a taxable year is passive income, or (ii) the average percentage of our assets (which include cash) by
(determined on a quarterly average) value in a taxable year which produce or are held for the production of passive income (which includes cash) is at least 50%. The calculation of the value of our assets will be based, in part, on the then
prevailing market value of our ADSs, which is subject to change. We cannot assure you that we will not be a PFIC for 2011 or any future taxable year. For more information on PFICs, see Item 10.E Additional InformationTaxationUnited
States Federal Income Taxation.

A. History
and Development of the Company

Our legal and commercial name is Chemspec International Limited. We are a holding company
incorporated in the Cayman Islands on May 30, 2006 to facilitate investment by foreign financial investors and as part of our restructuring conducted in 2006. We are a Cayman Islands exempted company with limited liability and our affairs are
governed by our memorandum and articles of association, as amended and restated from time to time, and the Companies Law (as amended) of the Cayman Island. Our current operations are conducted through our subsidiaries organized and located in the
PRC. Our ADSs have been listed on the New York Stock Exchange under the symbol CPC since June 24, 2009. Our principal executive offices are located at No. 200, Wu Wei Road, Shanghai 200331, Peoples Republic of China, and
our telephone number at this address is (86) 21-6363-9090. Our registered office in the Cayman Islands is at c/o Maples Corporate Services Limited, PO Box 309, Ugland House, Grand Cayman, KY1-1104, Cayman Islands. Our website address is

Shanghai ChemSpec Corporation, or Shanghai ChemSpec, was founded in November 1996 by
Dr. Jianhua Yang and Teng Zhou Rui Yuan Fragrance Factory, or Fragrance Factory. In April 2006, Wisecon Limited, or Wisecon, was incorporated in Hong Kong. The transfer of the equity interests in our operating subsidiaries to Wisecon was
completed in July 2006 for the purpose of establishing a corporate structure to facilitate the raising of capital from investors outside of China. In February 2006, Stanley Space Limited, or Stanley Space, was incorporated in the British Virgin
Islands as the holding company of Wisecon. The initial beneficial owner of Stanley Space was Dr. Jianhua Yang. Stanley Space Limited purchased all of the equity interests of Wisecon in April 2006 for HK$1.0. On May 30, 2006, to facilitate
investments by foreign financial investors, Chemspec International Limited, or Chemspec, was incorporated in the Cayman Islands. In August 2006, we issued ordinary shares to existing shareholders of Stanley Space in exchange for the respective
equity interest that these shareholders held in Stanley Space, and Chemspec International Limited became the ultimate holding company of our operating subsidiaries.

Shanghai ChemSpec Trading Co., Ltd., or Shanghai ChemSpec Trading, which was incorporated in June 1999 in the PRC as a wholly owned subsidiary of Shanghai ChemSpec Co., purchases raw materials and
supplies from suppliers located in China for our core manufacturing business. In October 2007, we transferred all our interests in Shanghai ChemSpec Trading to a third party. In addition, we entered into a series of share transfer agreements to
purchase 80% equity interests in Jiangsu Wei Er in January 2008. In March 2008, we acquired an additional 20% interest in Zhejiang Huajing Fluorochemical and Technology Company Limited, or Huajing Company, to increase our equity interest to 80%.
Furthermore, we acquired the remaining 20% equity interest in Jiangsu Wei Er for cash consideration of RMB 41,000,000 on November 5, 2009 and 100% of the equity interest of Jiangsu Kangpeng Nong Hua Co., Ltd., or Kangpeng Nong Hua for cash
consideration of RMB25,000,000 on November 9, 2009, respectively. On March 18, 2010, we also acquired the 8% minority equity interest of Binghai Kanjie Chemicals Co., Ltd., or Binhai Kangjie, from an independent third party for cash
consideration of

Going Private Transaction

On November 11, 2010, our board of directors received a proposal letter from Dr. Jianhua Yang, our founder, chief executive
officer and chairman of our board of directors, to acquire all of our outstanding shares in a going private transaction. On March 21, 2011, we entered into a definitive agreement and plan of merger with Halogen Limited, an entity jointly owned
by Dr. Jianhua Yang and an affiliate of Primavera Capital Management Ltd., or Primavera, and Halogen Mergersub Limited, or Merger Sub, a Cayman Islands exempted company wholly owned by Halogen Limited.

Under the terms of the merger agreement, each of our ordinary shares (including shares represented by ADSs, each of which represents 60
ordinary shares) issued and outstanding immediately prior to the effective time of the merger will be cancelled in exchange for the right to receive US$0.135 (or US$8.10 per ADS) in cash without interest (less US$0.05 per ADS cancellation fees
payable to the ADS depositary), except for the ordinary shares and ordinary shares represented by ADSs beneficially owned by Dr. Jianhua Yang, Mr. Yunlong Yuan and Mr. Weinian Qi which will be cancelled without receiving any
consideration.

Our board of directors, acting upon the unanimous recommendation of the independent committee, which is
composed solely of directors unrelated to any of Halogen Limited, Merger Sub, Primavera or any of our management members, approved the merger agreement and resolved to recommend that our shareholders vote to adopt the merger agreement. The
independent committee negotiated the terms of the merger agreement with the assistance of its financial and legal advisors.

The merger contemplated by the merger agreement is subject to the adoption of the merger
agreement by an affirmative vote of shareholders in accordance with Cayman Islands law and an affirmative vote of the majority of our disinterested shareholders that are present and voting in person or by proxy at a meeting of our shareholders, as
well as certain other customary closing conditions. Dr. Jianhua Yang has agreed to vote to adopt the merger agreement. Standard Chartered Bank (Hong Kong) Limited, or SCB, Halogen Limited and Merger Sub have entered into a facility agreement
pursuant to which SCB has agreed to provide financing for the transaction, subject to certain conditions. We will schedule a meeting of our shareholders for the purpose of voting on the adoption of the merger agreement. On May 3, 2011, we filed
a going private transaction statement on Schedule 13E-3 which attaches as an exhibit a preliminary proxy statement that, subject to completion, will be used in connection with the extraordinary general meeting of our shareholders, which we currently
expect to hold in the third quarter of 2011. If completed, the merger will, under Cayman Islands laws, result in us becoming a privately-held company and our ADSs would no longer be listed on the New York Stock Exchange. The Company, as the
surviving company, will continue to do business under the name Chemspec International Limited following the merger and will be wholly owned by Halogen Limited.

Based on the number of ordinary shares expected to be outstanding on the share record date, approximately 460,325,150 ordinary shares owned by unaffiliated shareholders must be voted in favor of the
proposal to adopt the merger agreement in order for the proposal to be approved, assuming all unaffiliated shareholders will be present and voting in person or by proxy at the extraordinary general meeting.

B. Business Overview

We
are a leading China-based contract manufacturer of highly engineered specialty chemicals.

We manufacture specialty chemicals,
which are typically highly engineered chemicals used as building blocks in the manufacture of more advanced chemicals or to enhance the performance of the end products manufactured by our end users in various industries including electronics,
pharmaceuticals and agrochemicals. In manufacturing specialty chemicals for our customers, we also provide process design and process development services, which enable efficient and rapid production of specialty chemicals that are incorporated into
our end users own products, thereby enhancing the value of our customers end products. We believe that our highly experienced management and research and development capabilities, our ability to rapidly respond to new customer processing
specifications and requirements, and our long-term cooperative relationships with our major customers distinguish us from many contract manufacturers of chemicals and that the need to develop some or all of these attributes to be competitive
effectively creates barriers to entry into the fields in which we operate. With our six major flexible and responsive manufacturing facilities, we are equipped to produce specialty chemicals in both small batches for development stage projects and
in large-scale amounts for commercialized projects, according to our customers needs. We refer to projects with sales of less than one metric ton per year, which typically indicates that they are still in a development or experimental stage, as
pipeline projects. We refer to projects with sales of one metric ton per year or more as commercialized projects. We sell our specialty chemicals directly to end users that incorporate them into their products and to trading
companies that then sell our products to final end users. We also assist certain of our long-term customers to source specialty chemicals from other producers in China. Since our establishment in 1996, we have developed a reputation for
collaborating with our customers to develop and introduce more sophisticated design processes to produce specialty chemicals that meet their specific requirements. We believe that our strong research and development capabilities, efficient
management of the manufacturing process and proven track record give us a competitive advantage over our competitors.

We have
a demonstrated record of providing tailored contract manufacturing solutions to end users in the major end markets that use specialty chemicals. In particular, we are a principal supplier of fluorinated specialty chemicals used in the manufacture of
thin film transistor liquid crystal displays, or TFT-LCDs, and other electronics. We are also a supplier of fluorinated specialty chemicals to a number of international pharmaceutical companies for use in a number of patented, FDA-approved drugs and
to agrochemical companies. We expect that sales of our fluorinated specialty chemicals used in pharmaceutical research, development and manufacturing will benefit from both the rapid pace of pharmaceutical innovation and the introduction of new
medicines and

##### Table of Contents

recent trends in the pharmaceutical industry towards outsourcing of production of specialty chemicals as well as certain product and research and development functions. We believe we are well
positioned to take advantage of increasing market demand for outsourcing of the design and manufacture of more complex and highly engineered specialty chemicals, including both fluorinated and other types of specialty chemicals.

We increased total headcount from 1,585 employees at the end of 2009 to 1,794 at the end of 2010. We also diversified our customer base
and built a solid foundation that will allow us to diversify our product mix from traditional chemical intermediates manufacturing into downstream Active Pharmaceutical Ingredients, or APIs, for the pharmaceutical industry and Active Ingredients, or
AIs, for the agrochemical industry. We received technology grants from the PRC central and local governments for four out of our six major manufacturing subsidiaries. Grants totaled RMB7.5 million (US$1.1 million) in the year 2010, a strong
recognition of our leading position in different technologies in many industrial fields in which we are actively involved. We also increased the number of approved patents from 11 at the end of 2009 to 15 at the end of 2010. We currently have 35
approved and pending approval patents.

Our Products

We manufacture specialty chemicals on a contract basis for our customers. The manufacture of these specialty chemicals includes chemical design, processing and manufacturing solutions tailored to our
customers specifications. The products we provide to customers are tailored to their requirements but generally include developing an efficient manufacturing process for the requested specialty chemicals, providing small-volume, pilot-level
production and then providing commercial level production of specialty chemicals. The specialty chemicals we manufacture generally contain fluorine and are developed and produced by us through proprietary processes tailored for each individual
specialty chemical with the qualities and performance characteristics required by the customer. These specialty chemicals are then incorporated into products made by our customers and end users for various applications in different industries, such
as electronics, pharmaceuticals and agrochemicals, depending on the end users own product specifications and applications.

The prices we charge for our products incorporate fees for our process development services, as we provide these services to customers who place orders for products or whom we expect will place orders for
products based on our previous transactions with them.

End Uses of Our Products

The products we manufacture are categorized as specialty chemicals in our industry, rather than as commodity chemicals. Specialty
chemicals are highly engineered and produced on a custom basis to customer or end-user specifications. Our products are used in various end markets, including electronics, pharmaceuticals and agrochemicals. The specialty chemicals we produce are
generally used by our customers and end users as intermediates, because they serve as building blocks for the manufacture of downstream products to produce a desired function or enhance performance.

Electronics Intermediates

The specialty chemicals we produce for the electronics industry are fluorinated intermediates primarily used in the production of TFT-LCDs and, to a lesser extent, other electronics products, such as
semiconductors.

Liquid Crystal Intermediates. Fluorine enables liquid crystal formulations to retain liquid
crystallinity with significantly reduced viscosity, resulting in much quicker response times and improved quality of TFT-LCDs. Our products are used as intermediates in the production of materials used by manufacturers of TFT-LCDs, primarily for
computer monitors and LCD televisions, or LCD TVs. Our TFT-LCD products have been historically used as intermediates to make liquid crystal materials. We continue to work with our end users of these products to develop more advanced generations of
specialty chemicals in this area, such as more complex, higher value-added multi-fluorine liquid crystal intermediaries, to further improve response time and picture quality of TFT-LCDs as the TFT-LCD industry continues to grow and develop.

##### Table of Contents

Other Electronics Materials. We also produce materials that are used in other
electronics applications, such as monomers for the synthesis of polymers used in the semiconductor industry, coatings and adhesives used in electronics manufacturing and specialty chemicals which increase the photo-sensitivity of products.

Pharmaceutical Intermediates

These specialty chemicals are used as pharmaceutical intermediates in the production of a variety of drugs, such as anti-depressants, diabetes medications, antibiotics, and pain killers. In recent years,
the use of fluorine substitution has aided the design and effectiveness of many new pharmaceutical drugs and has resulted in pharmacological agents with improved biological properties, including steroidal and non-steroidal, anti- inflammatory
agents, anticancer and antiviral agents and central nervous system drugs for the management of mental illnesses such as depression and psychoses.

We design production processes for our pharmaceutical products based on chemical structures identified by our customers. In the pharmaceutical sector, we typically target customers involved in the
development of new drugs that address large markets. By working with pharmaceutical customers on new projects that are generally in an early stage of development, we are favorably positioned to be one of the principal suppliers of specialty
chemicals for those customers when the drug reaches commercialization.

We also manufacture advanced chemical intermediates
that are of more general application in the pharmaceutical industry and are incorporated into a range of different pharmaceuticals by end users.

Agrochemicals

We also manufacture specialty chemicals used as
intermediates by agrochemical manufacturers and fine chemical companies. Our products in this category are used by large agrochemical manufacturers to make herbicides, pesticides and fungicides.

Process Development

In
manufacturing specialty chemicals, we work to optimize reaction processes in order to produce specialty chemicals more efficiently than through existing processes. By optimizing and selecting more effective methods of compound synthesis, we reduce
the cost of production for our customers. This may be achieved by reducing the quantity of raw materials or number of steps used in reactions, improving the yield of the requested specialty chemicals and accelerating the time needed for production
and the overall time-to-market of the product. Our manufacturing facilities are effectively configured to accommodate varying scales of production volume. Our kilo-lab is used to produce small quantities of specialty chemicals that are in the early
stages of development and are used on a test basis, or for complex specialty chemicals that are required only in small quantities. Our pilot plant is used to assist our customers during the development stage of products which they may order in
larger quantities at a later date. Customers then may move from ordering smaller scale test production, measured in grams, to scale-up quantities, measured in kilograms, to process optimization quantities, which are measured in hundreds of
kilograms, to commercial process development quantities, which are measured in tons. Through this range of services, we are able to meet the range of customer demands from clinical trials through commercialization and mass production.

Manufacturing Operations

We currently own and operate six major production facilities in China located in Shanghai, Jiangsu province and Zhejiang province. Each of
our facilities has the flexibility to produce any of our specialty chemicals. We are in the process of expanding our manufacturing capacity. See Headquarters and Facilities.

We also have the capability to employ specialized reaction technologies including low temperature (-80°C) reactions, organo-metallic
reactions, catalytic reactions, high-vacuum reactions, pressure reactions, and reactions that must be carried out under moisture-free and air-free conditions. Our manufacturing processes also involve the use of cryogenic processes, high reactive and
corrosive processes and high pressure processes.

##### Table of Contents

We outsource limited production of simpler raw materials and chemicals requiring lower
levels of technical expertise, including commodity chemicals, to third-party manufacturers in China, which enables us to focus our limited production capacity on more complex products that can be sold for higher prices.

We also have the ability to internally produce raw materials, such as fluorinated nitrobenzenes, which are essential ingredients used in
producing our specialty chemicals. This provides us with a competitive cost advantage and assists us in maintaining a steady source of supply for certain materials.

In December 2008, we entered into a joint venture agreement with Central Glass pursuant to which we have invested US$2.0 million (approximately RMB13.7 million) through Shanghai ChemSpec and Quzhou
Kangpeng to become a noncontrolling investor in the joint venture, which is named Central Glass Chemspec Company Limited. The production facility of Central Glass Chemspec Company Limited is currently under construction and does not generate revenue
or pay dividend to us.

Sales of Purchased Goods

We also assist customers to source from other producers in China specialty chemicals involving lower levels of technology that we do not normally manufacture ourselves. These sourcing projects, which we
also refer to as sales of purchased goods, generally involve locating appropriate sources of the specialty chemicals requested by our customers, examining the chemicals for quality assurance and purchasing and repackaging the chemicals under our
brand name for export to the customer. These sourcing projects fluctuate according to individual customer demand.

Our Customers

Our customers consist both of (i) trading companies that then sell our products to the actual end users and
(ii) direct end users, which primarily include electronics, pharmaceutical and agrochemical companies. We had 106 customers in seven countries and Hong Kong in 2010. Our end users include many of the leading global companies in the
pharmaceutical, agrochemical and electronics industries, including Central Glass Co., Ltd., Chisso Corporation, Eli Lilly and Company, Lonza Group Ltd. and Merck KGaA. Our end users also include several of the global top pharmaceutical companies and
several of the global top agrochemical companies in the world, as measured by sales of those companies in 2010. The majority of our end users are based in Japan, the United States and Europe. Our production methods and facilities have been audited
periodically by several major international pharmaceutical companies. To date, most of our customers have returned to us for additional and often larger volume and longer term projects. In accordance with industry practice, we sell substantially all
of our products on a purchase-order basis and generally do not enter into long- term contracts.

The table below illustrates
our growing customer base:

significant fluctuations or declines in our revenues and A payment failure by any of our large customers could significantly harm our cash flows and results of operations.

Sales, Marketing and Distribution

As a contract manufacturer with long-term relationships with many of our customers, we focus on cultivating our existing relationships, enhancing communications with them and responding to their
manufacturing needs.

##### Table of Contents

We periodically visit our customers to receive feedback on product quality, discuss their requirements and expectations, and anticipate production requirements. We also rely upon referrals
from existing customers to extend our customer base and participate in international product fairs and exhibitions in relevant industries to make new contacts and cultivate new customer relationships. We have close to fifteen employees involved in
sales and marketing, many of whom have technical expertise and industry knowledge.

Pricing of many of our products is based
upon negotiation with customers. The primary factors that affect pricing are the level of technological differentiation required, the complexity of the manufacturing process, the amount of time required for product development and ramp up to
commercial production levels, the level of research and development required to bring a new product to market, the cost of raw materials and the level of competition in the market.

Suppliers

Our suppliers are primarily located in China, and the principal
raw materials or essential ingredients used in the production of our products are generally readily available in China. Prices for our main raw materials and ingredients are generally driven by underlying petrochemical benchmark prices and energy
costs.

The raw materials that we purchased from our top five suppliers accounted for 35%, 26% and 36% of our total cost of
revenues in 2008, 2009 and 2010, respectively, representing 20%, 16% and 22%, respectively, of our sales in those years.

Our
principal raw materials include fluorine, hydrofluoric acid, and petroleum-based solvents. We purchase these raw materials from multiple suppliers at prevailing market prices, and alternative sources are generally available to enable our business to
continue in the event of any interruption from present sources. In general, we buy materials on an as-needed basis on the open market at the market price when customer orders are placed. We also undertake some internal production of raw materials
using our own facilities. See Manufacturing Operations.

Research and Development

We believe that in order to maintain and enhance our margins and remain competitive, we must continually invest in research and
development, product and process improvements and specialized customer services. Through research and development, we seek to introduce more highly engineered, higher-end specialty chemicals and more efficient and cost-effective manufacturing
processes. We emphasize a customer-driven approach in developing new and improved processes and providing superior customer service through our technical staff that are directly responsive and relevant to our customers needs. Furthermore,
through regular direct contact with our key customers and end users of our products, our research and development personnel accumulate relevant expertise and can better anticipate our customers and their end users requirements in
planning research and development projects.

Our research and development activities are based in our headquarters in
Shanghai. As of March 31, 2011, our research and development team included 101 research scientists and technicians, 16 and 22 of whom have received Ph.D. and M.S. degrees, respectively, in chemistry, engineering and other related sciences. Our
research and development facilities include a broad range of synthesis and testing equipment to help us develop new processes to produce the products which our customers desire. Our research and development efforts focus on improving the quality of
our products, decreasing the manufacturing time and time-to-market required for products and lowering manufacturing costs. We completed the construction of a new and state-of-art research and development center in Shanghai in October 2009. The
facility will be able to support up to 350 research scientists and will enhance our ability to develop new processes and assist customers in research and development.

Development of new production processes is integrated with quality assurance procedures.
Quality assurance procedures include strict record keeping of all procedures and processes and monitoring procedures to ensure the consistent application of our manufacturing processes. We also maintain quality control manuals for internal
distribution among our factory managers and employees to maintain consistent production standards. Periodic audits by several major international pharmaceutical companies also provide independent third-party monitoring and review of our facilities.
We also continuously focus on improving plant yields, lowering fixed costs and using our existing manufacturing capacity more efficiently for expanding sales.

We spent RMB27.5 million, and RMB30.9 million and RMB65.7 million (US$10.0 million) on research and development in 2008, 2009 and 2010, respectively.

Intellectual Property

We protect our and our customers intellectual property primarily by maintaining strict control over the use of production processes.
We also rely on confidentiality procedures and contractual provisions to protect our technology in cases where the technology is not patented or patentable. All of our employees are required to execute confidentiality and nondisclosure agreements
with us when their employment begins. In addition, for each project, only the personnel associated with the project have access to the related intellectual property. Access to proprietary data is limited to authorized personnel to prevent unintended
disclosure or otherwise using our intellectual property without proper authorization.

Due to the rapid pace of change in our
products as a result of constant changes in the requirements of our customers or the companies that use our products, we pursue only a limited number of patents. As of the date of this annual report, we had 16 patents granted by, and 19 patent
applications pending before, the State Intellectual Property Office of the PRC, or SIPO. The majority of these patents and patent applications relate to process patents.

Generally, we do not use the proprietary technology of others, in order to minimize the risk of patent infringement and to ensure that our products may be sold to any customer. In special cases,
technology transfer from the companies that use our products does occur pursuant to confidentiality agreements in order to expedite product delivery for those companies. In these cases, those companies generally indemnify us for the use of their
technologies.

Occupational Health and Safety

Our business operations involve significant risks and hazards that are inherent in such activities. These risks and hazards could result in damage to, or destruction of, properties or production
facilities, personal injury, environmental damage, business interruption and possible legal liability.

We regard occupational
health and safety as an important operational and social responsibility and we have implemented an internal system for environmental, health and safety. In compliance with law, we provide periodic health checks for all employees to reduce the risk
of work-related illnesses. In recent years, we have undertaken many measures to improve our facilities safety and we maintain a safety management system that sets targets against which performance is measured. We have adopted detailed safety
procedures based on production methods of each plant in compliance with national safety guidelines, including weekly safety inspections and training in safe work practices for our employees. In addition, our facilities have been audited and approved
by several major international pharmaceutical companies for compliance with their own quality assurance standards and PRC environmental, health and safety standards.

We have not had any fatalities in our production facilities. Although we have experienced minor accidents, including machinery incidents, our production facilities have not experienced major accidents
that we believe to have had, individually or in the aggregate, a material adverse effect on our business, financial condition or results

of operations. While we are committed to maintaining high safety standards at our production facilities, accidents may occur in the future. See Item 3. Key InformationD. Risk
factorsRisks Related to Our Company and Our IndustryOur operations are subject to various risks associated with our use, handling, storage and disposal of hazardous materials, many of which are toxic and flammable. If we are found liable
for contamination, injury to employees or others, or other harms related to our use, handling, storage and disposal of hazardous materials, our business, financial condition and results of operations will be adversely affected.

Environmental

Our
operations involve the use, handling, processing, storage, transportation and disposal of hazardous materials and our production processes generate noise, waste water, gaseous and other industrial wastes. Accordingly, we are subject to extensive
environmental, health and safety regulations at the national, provincial and local level in China, including those governing the discharge of pollutants into the air and water, the management and disposal of hazardous substances and wastes, the
maintenance of safe conditions in the workplace and the production, handling, labeling and use of chemicals used or produced by us, as well as requirements relating to operating permits that are subject to renewal or modification. Ongoing compliance
with such regulations is an important consideration for us and we are committed to conducting our operations in compliance with applicable regulations. However, we are exposed to the risk of claims for environmental remediation or restoration and
violations of environmental, health and safety regulations or permit requirements may result in restrictions being imposed on operating activities, substantial fines, penalties, damages or other costs.

We have consistently endeavored to maintain and improve our environmental, health and safety systems to try to maintain among the highest
standards of chemical manufacturers based in China and to respond rapidly and effectively to all regulatory developments requiring more stringent standards. For example, we maintain (i) water treatment facilities for recycling and to ensure
disposal of liquid waste that complies with all applicable laws and regulations, (ii) equipment to minimize noise pollution in compliance with local government regulations and (iii) high environmental and recycling standards that increase
the efficiency of our production. In addition, we generally dispose of gaseous emissions by collecting them as they are produced and dissolving them in our internal water system for disposal with liquid waste, and solid waste is disposed of through
qualified third- party contractors. However, in the past, certain of our manufacturing facilities have experienced environmental incidents as follows:



| |  |  | Jiangsu Wei Er: In 2007, prior to our acquisition of Jiangsu Wei Er, one of its production lines was temporarily shut down by local environmental
officials and the facility received a yellow annual rating, or third of five possible ratings, on a local environmental ratings review, indicating that it is compliant with national pollutant discharge standards but did not meet certain
other environmental protection standards. Subsequently, Jiangsu Wei Er implemented additional environmental measures and improved its local environmental rating to a blue annual rating for 2007, or second of five possible ratings. Since
acquiring Jiangsu Wei Er in early 2008, we have endeavored to apply our overall environmental, health and safety standards to this manufacturing facility and to maintain and improve the annual environmental rating of this facility in 2008. In early
June 2008, Jiangsu Wei Er was listed as a high security risk company in Yancheng City due to the historically inappropriate design of its chemical storage area, which was maintained close to a high-voltage electric transmission line at
the boundary of the local government chemical processing zone in which Jiangsu Wei Er is located, and which was deemed to present a potential fire accident and toxic material leak. In order to remedy this deficiency, we engaged the local chemical
processing zone authority to relocate this high-voltage electric line away from our chemical storage area and submitted a risk-elimination report, and in July 2008 the local authorities removed Jiangsu Wei Er from the list of high security
risk companies;

| |  |  | Shanghai Qi Yue: In January 2008, local customs officials in Shanghai discovered and confiscated a shipment of dangerous chemicals that had been
inappropriately declared by our subsidiary Shanghai Qi Yue due to an error in staff documentation processing resulting in a fine of RMB30,000. We have subsequently taken measures to strengthen and standardize our internal procedures and protocols
for completing customs documentation;

| |  |  | Taixing Chemspec: In October 2006, Taixing Chemspec was temporarily shut down by local officials due to the use of an inappropriate material in the
facilitys underground rain discharge pipelines and was ordered to rectify noncompliance with certain environmental protection rules. We refurbished the underground rain, sewage and manufacturing discharge pipeline systems of this facility to
comply with national and local environmental protection rules in late 2006. The facility was reopened later that year. In early 2008, during a nationwide safety risk assessment campaign, local safety production supervision officers discovered a
potential safety risk in Taixing ChemSpec related to the elevation of a fire water pipeline crossing our facility side gate was 0.5 meters lower than the national standard, which could have potentially blocked access to the fire safety route. As of
July 2008, we completed reconstruction of that side gate to elevate the fire water pipeline above the level required by the national standard.

We believe we are currently in compliance with applicable environmental regulations in all material aspects and have all necessary environmental and safety permits to operate our business as it is
presently conducted. We do not believe that any of the incidents described above have had, individually or in the aggregate, a material adverse effect on our business and we are not aware of any material breaches of any environmental laws or
regulations applicable to us. We believe that our environmental protection systems and facilities comply with applicable PRC national, provincial and local environmental protection laws and regulations in all material respects. The PRC government is
moving toward more rigorous enforcement of applicable environmental laws and regulations and the adoption of more stringent environmental standards. Such developments could affect our financial condition and results of operations. We expect to
continue to invest in our environmental control systems as the environmental regulatory regime in China develops. See Item 3. Key InformationD. Risk factorsRisks Related to Our Company and Our IndustryOur use, production and

necessary to conduct our business could materially harm our business and prospects.

Competition

We compete with a variety of companies, including large global chemical companies and small specialty chemicals companies, in the
specialty chemicals market. We believe the principal factors that determine competition in our industry include process development and innovation capabilities, quality of product, speed of production and rapid time-to-market manufacturing, ability
to produce a wide range of products according to users individual technical specifications while maintaining low costs and price. We primarily compete with other specialty chemicals manufacturers, such as Lonza Group Ltd., Evonik Degussa GmbH,
Lanxess AG, Balchem Corporation, Rohm and Haas Company, and Sigma-Aldrich Corporation, as well as some Chinese manufacturers, such as WuXi PharmaTech Co., Ltd., Asymchem Laboratories Co., Ltd., Xian Ruilian Modern Electronic Chemicals
Co., Ltd., Yantai Valiant Fine Chemicals Co., Ltd. and Zhejiang Yongtai Chemical Co., Ltd. Most foreign competitors are large chemical companies with manufacturing facilities located both in their own countries as well as in lower cost manufacturing
sites, including China. China-based competitors are generally small chemical companies.

We believe we compete favorably on
the basis of our rapid turnaround time, design and innovation capabilities, research and development teams, price and geography. We continue to differentiate ourselves from

our competitors by our speed of bringing new products to commercial production, our process design expertise, our efficient manufacturing processes and our focus on product quality and customer
service. In addition, we believe we maintain cost and manufacturing flexibility advantages as a China-based manufacturer versus international manufacturers which are based in higher-cost jurisdictions. Because of these competitive advantages, we are
able to maintain and expand our customer base with a steady and increasing revenue stream.

Employees

See Item 6. Directors, Senior Management and EmployeesD. Employees for certain information relating to our employees.

Headquarters and Facilities

We built and moved into our headquarter office in October 2009. Our principal headquarters are located at No. 200, Wu Wei Road, Putuo District, Shanghai, PRC. The majority of our senior management
team, administrative staff and research and development employees began to work in the new office buildings since October 2009. We currently own and operate six major manufacturing facilities in the eastern coastal region of China. The following

As
of December 31, 2010, we had aggregate reactor volume of 2.3 million liters.

Insurance

As of December 31, 2010, we carried approximately RMB891.7 million (US$135.1 million) of insurance coverage, which includes coverage
for certain of our property, plant and equipment and inventory, and for employee injury and third-party liability for all of our operations. We also have a D&O insurance with US$10 million coverage. We do not have insurance coverage on our other
assets, other types of litigations or product liability. We do not maintain business interruption insurance. We believe our coverage and insured limits are customary for similar companies in our industry in China. In addition, we carry medical,
third-party liability and unemployment insurance for our employees in compliance with applicable regulations.

We will
continue to review and assess our risk exposures and make necessary and appropriate adjustments to our insurance coverage in line with our needs and with industry practice with respect to insurance in China. If we were held liable for amounts and
claims exceeding the limits of our insurance coverage or outside the scope of our insurance coverage or if we suffer significant claims giving rise to increased premiums and deductibles, our business, results of operations and our financial
condition may be materially and adversely affected.

Legal Proceedings

We are not currently involved in any material litigation, arbitration or administrative proceedings. We may from time to time become a party to various litigation, arbitration or administrative
proceedings arising in the ordinary course of our business.

Regulation

Environmental Regulations

Our production processes generate noise, wastewater, gaseous and other industrial wastes, and our operating activities involve hazardous materials. We are subject to a variety of governmental regulations
related to environmental protection. The major PRC environmental regulations applicable to us include the Environmental Protection Law, the Environmental Impact Appraisal Law, the Law on the Prevention and Control of Water Pollution and
Implementation Rules of the Law on the Prevention and Control of Water Pollution.

The Environmental Protection Law sets out
the legal framework for environmental protection in the PRC. The Ministry of Environmental Protection, or the MEP, of the PRC is primarily responsible for the supervision and administration of environmental protection work nationwide and formulating
national waste discharge limits and standards. Local environmental protection authorities at the county level and above are responsible for the environmental protection in their jurisdictions.

Companies that discharge contaminants must report and register with the MEP or the relevant local environment protection authorities.
Companies discharging contaminants in excess of the discharge limits prescribed by the central or local authorities must pay discharge fees for the excess in accordance with applicable regulations, and are also responsible for the treatment of the
excessive discharge. Government authorities can impose different penalties on individuals or companies in violation of the Environmental Protection Law, depending on the individual circumstances of each case and the extent of contamination. Such
penalties include warnings, fines, impositions of deadlines for remedying the contamination, orders to stop production or use, orders to re-install contamination prevention and treatment facilities which have been removed without permission or left
unused, administrative actions against relevant responsible persons or companies, or orders to close down those enterprises. Where the violation is serious, the persons or companies responsible for the violation may be required to pay damages to
victims of the contamination. Where serious environmental contamination occurs in violation of the provisions of the Environmental Protection Law which results in serious loss of public and private property, persons or enterprises directly
responsible for such contamination may be held criminally liable.

Regulation on Work Safety

Our operating activities involve hazardous materials. We are subject to a variety of governmental regulations related to work safety. The
major PRC regulations related to work safety applicable to us include Production Safety Law, Regulation on Work Safety Licenses and Regulation on the Safety Administration of Hazardous Chemicals.

Work Safety Law

The Production Safety Law, or PSL, was promulgated for implementation as of November 1, 2002, and amended according to Decision of the Standing Committee of the National Peoples Congress on
Amending Some Laws which took effect on August 27, 2009. The PSL is applicable to the work safety for entities engaging in production and business operation activities within the PRC. Such entities must comply with the PSL and other relevant
laws and regulations concerning work safety and strengthen the administration of work safety, establish and perfect the system of responsibility for work safety, ensure conditions for safe production, and ensure safety in production.



45



---

##### Table of Contents

The PSL and other provisions of the relevant laws and regulations create a system for
affixing responsibility for work safety accidents and holding liable those found to be responsible for work safety accidents. Entities engaged in the production, operation and storage of hazardous substances, (i) should be subject to the
examination and approval as well as the supervision and administration of relevant administrative departments, according to the provisions of relevant laws and regulations, national standards or industrial standards; (ii) must have archived
files for substantial hazardous sources, make regular checks, appraisals, supervisions and controls, make emergency plans, and inform employees and other relevant people of the emergency measures that should be taken under emergency circumstances;
(iii) must report, according to the relevant provisions of the state, the substantial hazardous sources and the corresponding safety measures and emergency measures to the administrative department and other relevant departments of the local
peoples government in charge of the supervision and administration of work safety for archiving purposes; and (iv) must have exits in the sites of production and the dormitories of the employees which meet the requirements for emergency
dispersal of people, have eye-catching marks and be clear of obstructions. It shall be prohibited to close or obstruct the exits of the sites of production and business operation and the dormitories of the employees.

Regulation on Work Safety Licenses

The Regulation on Work Safety Licenses, or RWSL, was promulgated by the State Council on January 13, 2004 and came into force on the same date. According to the RWSL, an enterprise engaging in the
production of hazardous chemicals, or the Enterprise, must apply for a work safety license before production.

To obtain a
work safety license, the Enterprise must satisfy certain work safety conditions, which mainly include: (i) establishing and improving a system for work safety, and formulating a complete set of work safety rules; (ii) investing in safety
satisfying applicable work safety requirements; (iii) establishing administrative entities for work safety and installing full-time work safety administrative personnel; (iv) the principal of the enterprise and the work safety
administrative personnel who have passed the appraisal conducted by the competent authority; (v) ensuring that special personnel have passed the appraisal conducted by the competent authority, and have obtained qualification certificates for
special operations; (vi) ensuring employees have gone through work safety education and training; (vii) ensuring payment for the employment injury insurance for the employees in accordance with the relevant laws, regulations, standards and
rules; (viii) ensuring premises, work sites, safety facilities, equipment and technology meet the requirements of the relevant work safety laws, regulations, standards and rules; (viiii) providing employees with labor protection articles
which are up to the national standards or standards of the industrial sector concerned; (x) having the appraising of work safety in accordance with the relevant laws, regulations, standards and rules; (xi) establishing emergency rescue
plans for accidents; (xii) appointing entities or personnel specializing in emergency rescue, and providing necessary emergency rescue materials and equipment; and (xiii) satisfying other conditions from relevant laws, regulations,
standards and rules.

The valid period for a work safety license is three years. If a work safety license needs to be extended
upon its expiration, the Enterprise shall go through the extension procedures three months prior to such expiration with the administrative department from which the license is issued.

Regulation on Safety Administration of Hazardous Chemicals

The Regulation on Safety Administration of Hazardous Chemicals was promulgated by the State Council on January 26, 2002, and took
effect on March 15, 2002. This regulation sets forth general requirements for the production and operation of certain chemicals that are considered dangerous and listed in the Hazardous Chemicals Catalog, which shall be formulated and adjusted
from time to time by The State Administration of Work Safety of the PRC, or the SAWS, and other relevant state government authorities. The Regulation on Safety Administration of Hazardous Chemicals was further supplemented and elaborated by
subsequent regulations and rules. Under PRC law, the production, storage, usage, operation, transportation of chemicals in the Hazardous Chemicals Catalog and the industrial use of such chemicals require specific regulatory approval, licenses and
permits. In addition, in order to strengthen the supervision and regulation of the safe operation and production of



46

##### Table of Contents

chemicals in the Hazardous Chemicals Catalog, on October 8, 2002, the Commerce and Trade Committee of the PRC issued the Measures for the Administration of Registration of Hazardous
Chemicals, according to which the enterprises should, within six months of the publication of the Hazardous Chemicals Catalog, complete registration for the production and storage of hazardous chemicals. On the same date, the Commerce and Trade
Committee of the PRC also issued Measures for the Administration of Operating Licenses for Hazardous Chemicals, according to which, Operation License is required for the operation and sale of hazardous chemicals. Both of the two administration rules
took effect on November 15, 2002. Pursuant to these regulations, the producers of chemicals in the Hazardous Chemicals Catalog will need to meet certain production safety requirements and pass a safety inspection conducted by the relevant
government authorities. In addition, such producers will need to obtain the relevant work safety license prior to production.

Under the Regulations on the Administration of Precursor Chemicals which was issued by the State Council on August 26, 2005 and took
effect on November 1, 2005, enterprise that produce precursor chemicals of the third catalog are required to register with county-level branches of the SAWS within 30 days from when the enterprise set out its operation with precursor chemicals
of the third catalog. Operation enterprises that apply for purchasing the precursor chemicals which can be used as major materials for drug production shall submit certain certificates, including the business license and the certification of legal
use and demand, and shall obtain the purchase license upon the examination and approval of the supervisory and administrative department of food and drugs of the peoples government of the province, autonomous region or municipality directly
under the Central Government, or the public security organ of the peoples government of the province, autonomous region or municipality directly under the Central Government where the applicant is located.

Regulation on Labor Protection

The Labor Contract Law of the PRC was promulgated on June 29, 2007 and became effective on January 1, 2008. This law governs the establishment of employment relationships between employers and
employees, and the conclusion, performance, termination of, and the amendment to employment contracts. To establish an employment relationship, a written employment contract must be signed. In the event that no written employment contract was signed
at the time of establishment of an employment relationship, a written employment contract must be signed within one month after the date on which the employer starts engaging the employee.

PRC Patent Law

The PRC first allowed patents for the protection of proprietary rights, as set forth in the PRC Patent Law, in 1985, which was amended at the 6thSession of Standing Committee of the 11thNational Peoples Congress of the Peoples Republic of China on December 27, 2008 and took effect on
October 1, 2009.

Patent Prosecution

The patent prosecution system in China is different from the system in the United States in a number of ways. China, like most countries other than the United States, follows the first to file
principle. In other words, when more than one person files a patent application for the same invention, the patent will be granted to the person who first filed the application. The United States, in contrast, uses a principle of first to invent to
determine the granting of patents. In addition, the PRC requires absolute novelty in order for an invention to be patentable. Pursuant to this requirement, generally, with limited exceptions, any prior written or oral publication in or outside the
PRC, demonstration or use in the PRC before the patent application filing prevents an invention from being patented in the PRC. Conversely, inventors in the United States can generally file a patent application within one year after publication of
the invention if the inventor can demonstrate that the invention was made prior to the publication. Patents issued in the PRC are not enforceable in Hong Kong, Taiwan or Macau, each of which has an independent patent system. The fact that a patent
application is pending is no guarantee that a patent will be granted, and even if granted, the scope of a patent may not be as broad as that of the initial application.

##### Table of Contents

Patent Enforcement

When a patent infringement dispute arises, the patent holder or an interested party who believes the patent is being infringed may either
file a civil lawsuit or file an administrative complaint with a provincial or municipal office of the State Intellectual Property Office, or SIPO. A PRC court may grant the patent holders or the interested partys request for a
preliminary injunction before or during the legal proceeding. Damages for infringement are calculated as either the loss suffered by the patent holder or the interested party due to the infringement. If the loss cannot be ascertained, the damage
shall be calculated as the benefit gained by the infringer from the infringement. Typically, a patent holder in the PRC has the burden of proving that the patent is being infringed.

Compulsory Licensing

Under the PRC Patent Law, where the patent holder fails to utilize a patent technology without reason after the expiration of three years from the grant date of the patent and four years from the date of
the patent application being filed, or where the patent holder has been legally identified as having engaged in monopolistic behavior by utilizing the certain patent, an interested party which is qualified to utilize a patented technology, but fails
to obtain the license from the patent holder on reasonable terms and in a reasonable period of time, is entitled to apply to the State Intellectual Property Office (SIPO) for a compulsory license. A compulsory license can also be granted where a
national emergency or any extraordinary state of affairs occurs, where the public interest so requires, or where a registered invention is substantially superior to a prior invention in connection with technology that has a notable economic
significance and the application of the later invention relies on the application of the prior invention.

International
Patent Treaties

The PRC is also a signatory to all major intellectual property conventions, including the Paris Convention
for the Protection of Industrial Property, Madrid Agreement on the International Registration of Marks and Madrid Protocol, Patent Cooperation Treaty, Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purposes
of Patent Procedure and the Agreement on Trade-Related Aspects of Intellectual Property Rights, or TRIPs.

Although patent
rights are national rights, there is a large amount of international co-operation under the Patent Cooperation Treaty, or the PCT, to which China is a signatory. Under the PCT, applicants in one country can seek patent protection for an invention
simultaneously in a number of other member countries by filing a single international patent application.

Foreign
Exchange Regulation

See Item 10. Additional InformationD. Exchange Controls.

Dividend Distribution Regulation

The principal laws and regulations governing dividends paid by our PRC operating subsidiaries include the Company Law of the PRC (1993), amended and effective as of January 1, 2006, Wholly Foreign
Owned Enterprise Law (1986), as amended in 2000, Implementation Rules of Wholly Foreign Owned Enterprise Law (1990), as amended in 2001, Chinese-Foreign Joint Venture Law (1979), as amended in 2001, and Implementation Regulation of Chinese-Foreign
Joint Venture Law (1983), as amended in 2001. Under these laws and regulations, each of our PRC subsidiaries, including WFOEs, joint venture enterprise and domestic companies in China may pay dividends only out of their accumulated profits, if any,
determined in accordance with PRC accounting standards and regulations. In addition, each of our PRC subsidiaries, including WFOEs, joint venture enterprise and domestic companies, is required to set aside at least 10.0% of its after-tax profit
based on PRC accounting standards each year to its general reserves or statutory capital reserve fund until the



48

##### Table of Contents

accumulative amount of such reserve reaches 50.0% of its respective registered capital. These reserves are not distributable as cash dividends. Furthermore, each of our WFOEs and joint venture
enterprise in China is also required to allocate a portion of its after-tax profits, as determined by its board of directors, to its staff welfare, employment injury insurance and bonus funds, which may not be distributed as cash dividends.

Tax

See Item 10. Additional InformationE. Taxation.

Provisions Regarding Mergers and Acquisitions of Domestic Enterprises by Foreign Investors

On August 8, 2006, six PRC regulatory agencies, including the Chinese Securities Regulatory Commission, or CSRC, promulgated a rule
entitled Provisions Regarding Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the new M&A rule, which was amended by Order No. 6 [2009] of the Ministry of Commerce on June 22, 2009, to more
effectively regulate foreign investment in PRC domestic enterprises. The new M&A rule took effect on September 8, 2006. The new M&A rule also contains a provision requiring SPVs formed for overseas listing purposes and controlled by PRC
individuals to obtain the approval of the CSRC prior to publicly listing their securities on an overseas stock exchange.

The
application of this new M&A rule is currently unclear. However, our PRC counsel, Jin Mao PRC Lawyers, has advised us that based on their understanding of the current PRC laws, rules and regulations and the new M&A rule, the new M&A rule
does not require that we obtain prior CSRC approval for the listing and trading of our ADSs on the NYSE, because our acquisition of the equity interest in our PRC subsidiaries is not subject to the new M&A rule due to the fact they were already
foreign-invested enterprises before September 8, 2006, the effective date of the new M&A rule.

Jin Mao PRC Lawyers
has further advised us that their opinions summarized above are subject to the timing and content of any new laws, rules and regulations or clear implementations and interpretations from the CSRC in any form relating to the new M&A rule.

See Item 3. Key InformationD. Risk factorsRisks Relating to Doing Business in ChinaThe approval of
the Chinese Securities Regulatory Commission, or the CSRC, might have been required in connection with our initial public offering, and, if required, we could be subject to sanction, fines and other penalties.

Regulations Relating to Employee Share Options

Pursuant to the Implementation Rules of the Administration Measure for Individual Foreign Exchange, or the Individual Foreign Exchange Rule, and an implementation notice on the rule, issued in January and
March 2007, respectively, by the SAFE, PRC citizens who are granted share options by an overseas publicly-listed company are required, through a PRC agent designated by such overseas publicly-listed company, to register with the SAFE and complete
certain other procedures related to the share options. PRC agents may be the subsidiary of such overseas publicly-listed company, trade union of any such PRC subsidiary having legal person status, a trust and investment company or other financial
institution qualified to engage in assets custodian business. Such individuals foreign exchange income received from the sale of shares or dividends distributed by the overseas publicly-listed company must first be remitted into a collective
foreign exchange account opened and managed by the PRC agent before distribution to such individuals in a foreign currency or in RMB. We and our PRC citizen employees who have been granted share options, or PRC optionees, will be subject to these
rules when our company becomes an overseas publicly-listed company. If we or our PRC optionees fail to comply with these regulations, we or our PRC optionees may be subject to fines and legal sanctions. However, as these rules have only been
recently promulgated, it is currently unclear as to how these rules will be interpreted and implemented.

Overview

We are a leading China-based contract manufacturer of highly engineered specialty chemicals. We have established a loyal base of customers
and end users who purchase or use our products and have returned to us with requests for new products. The end users of our products purchase them either directly from us or through chemical trading companies. In 2008, 2009 and 2010, we sold
products for 50, 59 and 68 commercialized projects and 65, 72 and 84 pipeline projects to a total of 71, 107 and 106 customers, respectively. Our end users include Central Glass Co., Ltd., Chisso Corporation, Eli Lilly and Company, Lonza Group Ltd.
and Merck KGaA. Our end users also include several of the top global pharmaceutical companies and several of the top global agrochemical companies in the world, as measured by sales in 2010.

Our business, especially the chemicals used in the electronics end-market, recovered in 2010 from the global financial crisis. The total
sales in 2010 passed the milestone of RMB1 billion. This is a testimony of our relentless effort in the year to expand our business development and strengthen the relationship with our customers, especially after the downturn of 2009. We will
continue to take certain measures to ensure a stable growth of our business. These measures include:



| |  |  | continuing to work closely with our customers in order to provide them with customized services and maintain long-term customer relationships;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | expanding our research and development facilities in order to provide higher value-added services to our customers and to develop more efficient
production processes that reduce raw material costs and increase the amount of recycled materials; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | continuing to expand into diverse end markets, including growth areas such as the pharmaceutical and agrochemical industries.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------

To address manufacturing constraints, we have been constructing new manufacturing facilities in order to
position ourselves to take on all projects requested by our customers. In 2010, we spent RMB244.1 million (US$37.0 million) in capital expenditures to expand our R&D and production facilities and reduce bottlenecks that have impeded growth, at
times, in the past. Total reactor volume increased from 2.0 million liters at the end of 2009 to 2.3 million liters at the end of 2010. Additional reactors will be installed after the completion of the current phase of expansion in 2011.
Currently, we own and operate six major production facilities in China. See Item 4. Information on the CompanyB. Business OverviewHeadquarters and Facilities. Our manufacturing facilities provide the flexibility to produce
any of the specialty chemicals we manufacture in varying quantities, as the volume of our individual reactors range from 50 liters to 10,000 liters.

We increased total headcount from 1,585 employees at the end of 2009 to 1,794 at the end of 2010. We received technology grants from the PRC central and local governments and the grants totaled RMB7.5
million (US$1.1 million) in the year 2010a strong recognition of our leading position in different technologies in many industrial fields in which we are actively involved. We also increased the number of approved patents from 11 by the end of
2009 to 16 by the end of March, 2011. We currently have 35 approved and pending approval patents.

In November 2009, we
acquired a 100% equity interest in Kangpeng Nong Hua for cash consideration of RMB25 million (US$3.7 million). As our Chairman and CEO, Dr. Yang held more than 50% voting ownership interest of both the Company and Kangpeng Nong Hua at the date
of the acquisition, it was considered a transaction between entities under common control. Therefore, our consolidated financial statements have been retroactively adjusted to reflect the combined entities for the periods during which the entities
were under common control.

In 2010, we substantially completed our share repurchase plan announced on
September 22, 2010. The total funds used in the share repurchase plan were RMB11.0 million (US$1.6 million).

We had
sales of RMB942.5 million, RMB820.3 million and RMB1,082.0 million (US$163.9 million) and net income attributable to our shareholders of RMB312.4 million, RMB172.4 million and RMB225.5 million (US$34.2 million) in 2008, 2009 and 2010, respectively.

Sales

Our
sales are derived from the sale of specialty chemicals, which include the sales from commercialized projects, pipeline projects and sales of purchased goods. In connection with our manufacture of specialty chemicals we sell to our customers, we
perform certain process and design engineering activities. Our sales are based upon the price and volume of chemical compounds we sell. The price we charge for specialty chemicals for commercialized and pipeline depends highly on the level of
complexity involved in manufacture of such products, while prices for products sold as purchased goods depend on market prices for the goods. We price our products based on several factors, including manufacturing costs, product life cycle,
complexity of the chemical compounds and order size, and, to a lesser extent, our relationship with the customer and the distribution method required.

Factors Affecting Our Sales

We believe that the most significant
factors that affect our results of operations are:

Global Economic Conditions

Global economic conditions affect our sales.
The global financial crisis and economic recession in previous two years contributed to the failure of key businesses, declines in consumer wealth estimated in the trillions of U.S. dollars, substantial financial commitments incurred by governments,
and a significant decline in economic activity. Faced with one of the most challenging years in our history, our sales were largely affected in 2009. Significant decreases in demand for consumer electronics, beginning in the second half of 2008
brought on by the global economic downturn resulted in decreases in demand for our specialty chemicals used in the manufacture of TFT-LCDs in 2009. In addition, significant decreases in demand for agrochemicals beginning in the second half of 2009
resulted in decreases in demand for our specialty chemicals used in the agrochemical market in the second half of 2009. Mild recovery in demand for such products began in the first half of 2010. The recovery of the global economic conditions greatly
attributed to our strong sales in 2010. The 2010 financial results reflected a strong upswing in demand in our end markets, particularly in the electronics sector where our highly engineered specialty chemical products are used.

Successful Commercialization of Products

Our sales are primarily driven by (i) the number and size of projects we complete for customers and (ii) the average selling prices of our products. The number and size of projects we complete
for customers are affected



52

##### Table of Contents

by market demand for our products and their end products, and the average selling prices are affected by the lifecycles of our products and of the end products into which they are incorporated,
among other factors. During the early stages of each products lifecycle, the volume sold is generally lower and the average selling price is generally higher, while as the product matures, the volume sold generally increases but the average
selling price generally decreases. Our ability to add new successfully commercialized products and enhance mature products, such as specialty chemicals for new end products and new generations of existing end products, will affect our sales in
future periods.

Many customers and end users choose us for our ability to provide tailored design and process engineering to
enable more efficient and rapid production of chemical intermediates for products still in a development stage. Many of these projects and small quantity orders are experimental and developmental in nature and may not successfully reach
commercialization. We expect our revenues will increase as more of these projects successfully reach the stage of large-scale commercial production.

In particular, many of our pipeline projects involve specialty chemicals used in the production of pharmaceutical end products that are in a developmental stage. As drug companies develop and test new
drugs, they conduct extensive research and development activities. In recent years, fluorine substitution has aided the design and effectiveness of many new drugs and has resulted in pharmacological agents with improved properties. Pharmaceutical
companies have asked us to supply them with customized fluorinated specialty chemicals for use in their research and clinical development activities. Certain drug candidates that are developed using specialty chemicals that we produce may prove
effective and obtain governmental approval in the future. If those approvals are obtained, and if those pharmaceuticals end products are successfully commercialized, we may be able to supply these pharmaceuticals companies with increasing quantities
of our products for use in their commercial production. Thus, our future growth will be affected by the level of expenditures by drug companies on research and development activities, the number of drugs containing our products that receive the
requisite regulatory approvals and are sold commercially and the demand for those approved drugs in the market. Some of these pipeline projects may not successfully reach commercialization. However, as more of these pipeline projects become
commercialized, we expect our total sales to increase in future periods because commercialized projects generate greater sales volume.

Expansion of the End Markets for Our Products

Our sales growth is driven
in part by growth in the end markets where our chemical intermediates are ultimately incorporated, such as the electronics, pharmaceuticals and agrochemicals industries. Our customers consist of direct end users as well as trading companies that
then sell our products to end users. Most of those end users are in the electronics, pharmaceuticals and agrochemicals industries. While some of our sales are to direct end users, a significant proportion of our sales are made to trading companies
that act as middlemen in the industry and who ultimately sell our products to end users for multiple industry applications. Due to this sales model, there is a degree of uncertainty about the identity of the ultimate end users of some of our
products and accordingly about the industries in which our products are used. Accordingly, the estimated percentages of our sales attributable to each end user market represent our best estimates based primarily on the compositions of the various
products we sell as well as our understanding of our customers and end users. The remaining portion of our sales not attributed to any particular end market during each period represents sales of purchased goods we made to our customers.

The largest percentage of our sales has historically been derived from end users in the electronics industry. The majority of these sales
have been driven by increases in demand for TFT-LCD units into which our products are incorporated. We estimate that approximately 46% to 53%, 45% to 52% and 62% to 69% of our sales in 2008, 2009 and 2010, respectively, were derived from specialty
chemicals sold to or used by end users in the electronics industry. Increases in the average screen size of TFT-LCDs sold and a shift in the orders of our customers towards production of higher-value-added components for liquid crystal formulations
for larger LCD televisions drove increases in our sales.

##### Table of Contents

The demand in the TFT-LCD electronics industry started to strongly recover in the first
quarter of 2010 and the momentum lasted into the third quarter of 2010. The sales gradually slowed down in the fourth quarter of 2010 due to the seasonally weaker demand in the end-market.

Historically, the second largest percentage of our sales has been derived from end users in the pharmaceutical industry. We estimate that
approximately 21% to 28%, 29% to 36% and 20% to 27% of our sales in 2008, 2009 and 2010, respectively, were derived from specialty chemicals sold to or used by end users in the pharmaceutical industry.

Historically the smallest source of sales of our products has been derived from the agrochemicals industry. We estimate that
approximately 10% to 17%, 10% to 17% and 14% to 21% of our sales in 2008, 2009 and 2010, respectively, were derived from specialty chemicals sold to or used by end users in the agrochemicals industry.

In addition, the growing trend towards outsourcing the production of these specialty chemicals to high quality manufacturers in China is
particularly important to our sales growth. See Item 3. Key InformationD. Risk FactorsRisks Related to Our Company and Our IndustryIf the end markets for our specialty chemicals do not grow, or if our customers do not succeed
in increasing their market shares in those markets, our business prospects and results of operations could be harmed.

Dependence on a limited number of customers

We depend on a small group of customers for a substantial portion of our sales. In aggregate, our top three customers accounted for 65%, 61% and 65% of our total sales in 2008, 2009 and 2010,
respectively. Our single largest customer accounted for 35%, 24% and 33% of our total sales in 2008, 2009 and 2010, respectively. We are increasing the level of our collaboration with major customers with whom we have long-standing relationships to
produce increasingly more complex and higher value-added products, including specialty chemicals for electronics, pharmaceuticals and agrochemicals. In addition, our sales are currently concentrated among customers who use our products in a limited
number of end users. In particular, many of our large customers historically have been companies or suppliers for companies that use our products in the manufacture of TFT-LCDs.

Historically, we have maintained a limited customer base due to our preference to work with customers with whom we have existing
long-term relationships, and many of them have repeatedly come to us for the development and manufacture of new products. As a result of our operating at or near our full manufacturing capacity in the past, we avoid using our limited capacity to
develop and manufacture lower value-added products and instead focus our resources on higher value-added products, and we typically give preference to existing customers when deciding which projects to pursue and which orders to accept. While we
believe that our close working relationships with our limited customer base offers us some competitive advantages, such as positioning us to become a primary supplier of newly developed and complex specialty chemicals products with higher average
selling prices, any fluctuations in demand from any one of our large customers may have a pronounced effect on our total sales.

Our largest customers historically order varying amounts of our products, making our results of operations difficult to predict and
likely to fluctuate between periods. In addition, we may not be able to retain existing customers or add to our existing customer base. The level of customer concentration we experience varies with the industry into which the end product
incorporating our product is sold. Although we rely on a few key customers for sales of our chemical intermediates used in electronics, we sell products that are used in pharmaceutical research, development and manufacturing, on the other hand, to a
relatively large number of customers.

Our business is affected by competition in the market for the products that many of our
major customers sell, and any decline in their businesses could reduce purchase orders from these customers. Our customers have



54

##### Table of Contents

sought, from time to time, to prospectively renegotiate pricing terms with us or obtain more favorable terms upon renewal of the contracts. Any adverse revisions to the terms of our arrangements
with our key customers could have a material adverse effect on our business and results of operations. We expect that our operating results will, for the foreseeable future, continue to depend on the sale of our specialty chemicals to a relatively
small number of customers, particularly with respect to products used in the electronics industry. Further, we expect that our results will continue to fluctuate and be difficult to predict as a result of customer concentration, demand experienced
by our customers and the level of demand in the end markets served by our customers.

On the other hand, our relentless
efforts to expand our customer base in the pharmaceutical and agrochemical business fields has been gradually paying us off as we have successfully established good communications with several global agrochemical leaders and biopharmaceutical
players, started initial quality validation processes with them and even started some sample productions for them, including our first contract manufacturing of an Active Pharmaceutical Ingredient, or API, under Current Good Manufacturing Practice,
or cGMP, condition for a new phase I stage drug of a biopharmaceutical company in the first quarter of 2010, and projects including Investigational New Drug, or IND enabling studies. Our state-of-the-art GMP facility has been fully operating
under the ICH Q7 guideline and has been audited by several clients.

Geographic Concentration of Sales

We sell our products to trading companies, as well as directly to end users. When we make sales to trading companies, it is not always
possible to determine the final country where our products are used by the end user. However, our sales have historically been concentrated in a limited number of countries, most notably Japan and Germany, where a significant portion of the end
users of our products are located. As a result of this geographic concentration, our financial performance could be affected by events such as changes in foreign currency exchange rates, trade protection measures, changes in regional or worldwide
economic, political or natural conditions, particularly conditions, changes and regulatory measures in Japan and Germany. For additional information regarding our geographic concentration of sales, see Note 18 of our consolidated financial
statements for the years ended December 31, 2008, 2009 and 2010 included elsewhere in this annual report.

Product Mix

The mix of our products also affects our sales. In 2006 and 2007, when we were already operating near our full
manufacturing capacity, we were required to choose which projects to pursue and which orders to accept. Producing a greater percentage of highly-engineered and newly-developed products will generally result in higher sales because these products
usually command higher average selling prices. In 2008, Jiangsu Wei Er also contributed to an adjustment in our product mix through its production and sales of large volumes of products with lower average selling prices. We expect to gradually
migrate Jiangsu Wei Ers product mix over time towards more highly engineered products with higher average selling prices to converge with our overall product mix. In 2009, the demand for specialty chemicals used in the production of TFT-LCDs
and agrochemicals decreased in line with the global economic slowdown. In 2010, the demand in the TFT-LCD end-market recovered since the first quarter of 2010, which contributed to the growth of total sales. As a result, the evolution of our product
mix has affected our sales and will affect our sales for the foreseeable future.

In addition, our ability to maintain or
increase our sales in products used in important end markets such as electronics, pharmaceuticals and agrochemicals will depend to a significant degree upon our ability to continuously convert our product range to newer, more advanced intermediates
and to the more complex components for specialty chemicals intermediates that we are able to sell at higher prices.

Our sales
are also influenced by the other projects we take on from time to time for our long-term customers. In particular, we assist some of our long-term customers to source from other producers in China specialty chemicals involving lower levels of
technology that we do not normally manufacture ourselves. These sourcing projects, which we also refer to as sales of purchased goods, generally involve locating appropriate



55

##### Table of Contents

sources of the specialty chemicals requested by our customers, examining the chemicals for quality assurance, purchasing and repackaging the chemicals under our brand name for export to the
customer. These sales of purchased goods fluctuate according to individual customer demand and generally have significantly lower gross margins than our commercialized and pipeline products. While we may experience periodic increases in these
orders, based on trends and customer requests we expect these sales of purchased goods to decrease in the foreseeable future.

Manufacturing Capacity

Our manufacturing capacity also affects our sales. For example, in 2006 and 2007, when we were already operating near our full manufacturing capacity, we could not accept all requested projects and orders
from our customers. In addition, the expansion of manufacturing capacity requires time to (i) construct the facilities, (ii) obtain the necessary permits and certifications for operations, and (iii) recruit and train the employees for
the new manufacturing facilities. We have been addressing the manufacturing constraints through the construction of new facilities and the acquisition of Jiangsu Wei Er in February 2008. Following these capital investments, we have substantially
reduced the manufacturing constraints due to the added capacities. The availability of spare manufacturing capacity will often determine which projects and orders we accept, and we expect an expansion in manufacturing capacity to expand our sales in
the foreseeable future. See Item 4. Information on the CompanyB. Business OverviewHeadquarters and Facilities.

Cost of sales

Our total
cost of sales amounted to RMB548.5 million, RMB495.6 million and RMB664.8 million (US$100.7 million) in 2008, 2009 and 2010, respectively. The following table sets forth our cost of sales by amount and as a percentage of total sales for the periods
indicated:

Our cost of sales consists primarily of raw material costs, including solvents, initial building blocks and
catalysts. The primary raw materials used in our manufacturing process include various petrochemical-based initial building blocks, fluorine and hydrofluoric acid, benzene, potassium fluoride and palladium or activated carbon catalysts. We purchase
raw materials in various states of production, and, in some instances, our raw material costs include outsourcing costs payable to third-party manufacturers. Our cost of sales also includes utility costs, direct labor costs, material consumption in
overhead, depreciation and other overhead.

We expect our cost of sales, including our raw materials costs, to increase
significantly in absolute terms as our manufacturing business expands and as prices for fluorine-based materials continue to exhibit an upward trend, and the labor cost in China continues to increase, offset in part by (i) improvements in our
manufacturing processes that reduce the raw materials consumed in production, (ii) economies of scale derived from better bargaining power and (iii) volume discounts associated with larger purchases. We expect cost of sales as a percentage
of sales to fluctuate in the near future as a result of a change in our product mix. While we expect raw material costs to increase in the future, we believe that the increase will be partially offset by our continued refinement of our manufacturing
processes, which focus around using less raw materials and manufacturing more efficiently.

##### Table of Contents

Our cost of sales as a percentage of sales may also fluctuate as we commence production at
new or revamped facilities, acquire additional production facilities or start to produce large quantities of new products. New or acquired facilities may affect our product mix and significantly increase our material costs temporarily or over a
longer period of time, both of which could result in fluctuations to our cost of sales as percentage of sales.

Our cost of
sales also includes that portion of the value added tax, or VAT, we are required to pay after taking into account any refunds we receive. In general, VAT at a rate of 17.0% is assessed on our sales outside of the PRC, less any deductible VAT already
paid or borne by the taxpayer. Pursuant to the Provisional Regulation of China on Value Added Tax and its implementing rules, all entities and individuals that are engaged in the sale of goods, the provision of processing, repairs and replacement
services and the importation of goods in China are generally required to pay the VAT. When we export goods, we are entitled to a portion or all of the refund of VAT that we have already paid or borne. Imported raw materials that are used for
manufacturing export products and are deposited in bonded warehouses are exempt from import VAT. Pursuant to recent changes in policy, on average, the refund rate we are entitled to receive is between 9% and 13%.

Gross profit and gross profit margin

Changes in our gross profit and margin from period to period are primarily driven by pricing conditions, product mix, volume of sales, raw material costs, labor cost, exchange rate variations and the
stage in the life cycle of the projects. Our gross profit and margin can also be affected by temporary market trends. For instance, we enjoyed enhanced gross margins from 2005 to 2007 in large part because of exceptional demand for specialty
chemicals used in the electronics industry, as that sector experienced strong global growth during those periods. Our gross margin gradually decreased from 2008 to 2010 because of the shift in product mix and the price adjustment of certain
products. We expect we may also face some gross profit margin compression due to the following: (i) our average selling price has generally been decreasing due to renegotiations in pricing terms with our customers once a product reaches a
certain scale of production, (ii) our raw material costs are expected to continue to increase as the global economy recovers, (iii) anticipated appreciation of the Renminbi relative to the U.S. dollar, which would have a negative impact on
our gross margins as much of our sales are denominated in U.S. dollars while much of our costs are denominated in Renminbi, (iv) increasing labor costs, and (v) fluctuations in the volume of sales of purchased goods we make, as these sales
are generally made on a cost-plus basis and, accordingly, generally have lower gross margins than our commercialized and pipeline products. Starting in February 2008, after we acquired Jiangsu Wei Er and substantially entered into the agrochemical
business, the decreasing trend in the average selling price of our products was attributable to the volume of products with lower average selling price produced by Jiangsu Wei Er in the agrochemical market. We expect to offset the pressure on our
gross profit margin to a certain extent by focusing our product range on higher-value-added specialty chemicals involving greater process design and process development expertise, which allows these products to command higher prices. In addition, we
expect our continued research and development efforts to further improve our manufacturing process to use less raw materials and manufacture more efficiently, which will help us partially improve on our gross profit margin.

Selling expenses

Selling expenses accounted for 1.3%, 1.4% and 1.0% of our total sales in 2008, 2009 and 2010, respectively. Our selling expenses consist primarily of freight, delivery and packing costs of our products to
either the port of Shanghai or the customers designated destination, shipping insurance, local taxes and customs fees, and other miscellaneous items. We ship our products either by sea or by air depending on our customers requirements
and certain of our contracts require us to pay freight and shipping costs. Freight and shipping costs accounted for 72.8%, 53.6% and 73.1% of our selling expenses in 2008, 2009 and 2010, respectively. The increase in shipping costs as a percentage
of sales and in absolute terms in 2010 was largely the result of more products were delivered by flight and higher cost of transportation compared with 2009. We expect that our selling expenses will increase in absolute amount and remain relatively
stable as a percentage of sales due to the fact that most of these selling expenses, such as shipping costs, are related to the volume of our sales.

General and administrative expenses

General and administrative
expenses accounted for 6.3%, 8.5% and 7.2% of our total sales in 2008, 2009 and 2010, respectively. General and administrative expenses consist primarily of salary and benefits for our management and administrative personnel (including share-based
compensation), office expenses, traveling and entertainment expenses, insurance premiums, depreciation on the headquarters, computers and other office equipment, consulting and auditing fees, and other administrative costs and expenses. Beginning in
2008, general and administrative expenses also include an allocation of our share-based compensation charges with regard to management and administrative staff. See Critical Accounting PoliciesShare-Based Compensation
Expenses.

We expect our general and administrative expenses to increase in an absolute term as our business expands in
2011. In addition, as the Company is in the process of a going private transaction, professional service fees to the legal counsels and the financial advisor and other associated fees will be incurred in 2011. See Item 4. Information on the
CompanyA. History and Development of the CompanyGoing Private Transaction.

Research and development expenses

Research and development expenses accounted for 2.9%, 3.8% and 6.1% of our total sales in 2008, 2009 and 2010, respectively. Research and
development expenses consist primarily of (i) the cost of raw materials and equipment used in conducting research, experimentation and product and process development, (ii) salaries and associated benefits paid to employees involved in
conducting research and development activities (including share-based compensation), and (iii) depreciation associated with the facilities and equipment used in connection with our research and development activities.

We expect to devote more efforts to research and development in the future and expand into more advanced specialty chemicals that require
sophisticated engineering and process development to produce. We have built a new research and development center in Shanghai and moved in the facility in the fourth quarter of 2009. Our research and development expenses included depreciation of
this facility during 2010. We expect that our continued efforts to improve our research and development activities and processes will help us further reduce internal test failure rates and achieve greater efficiency in raw material usage during
research and development processes. In addition, we anticipate that by continuing to focus on our core fluorinated specialty chemicals and technologies and by leveraging them to selectively expand into new business areas, we may control research and
development expenses as a percentage of our total sales.

Other operating expenses

Other operating expenses accounted for 0.2%, 0.9% and 0.3% of our total sales for 2008, 2009 and 2010, respectively. Other operating
expenses consist primarily of loss on disposal of property, plant and equipment and miscellaneous costs and expenses.

Other operating income

Other operating income accounted for 0.1%, 0.1% and 0.2% of our total sales for 2008, 2009 and 2010, respectively. Other operating income in 2008, 2009 and 2010 consisted primarily of rental income from
the lease of plant and equipment.

Government grants

Government grants we receive from local government authorities are provided to reimburse our research and development-related
expenditures. We submit applications to the government for grants in relation to research and development-related projects each year. The government may not approve the grants in the same year as the applications were submitted. In addition, the
amount granted may vary depending on government policy and other considerations. Accordingly, we cannot predict the timing or the amount of government grants approved in relation to our applications, and as a result, the amount we receive from
government grants may fluctuate from year to year.

Interest expense

Interest expense consists of interest expense associated with finance costs for loans. We had short-term bank borrowings of RMB65.0
million as of December 31, 2008, long-term bank borrowings of RMB10.0 million as of December 31, 2009 and short-term bank borrowings of RMB20.0 million (US$3.0 million) and long-term bank borrowings, current portion, of RMB5.0 million
(US$0.8million) as of December 31, 2010. These borrowings are secured by credit facility, our properties and land use rights or by our consolidated subsidiaries. The secured short-term bank borrowings and long-term bank borrowings, current
portion, as of December 31, 2008 and 2010 bore weighted average interest rates 7.984% and 5.274% per year, respectively. All short-term bank borrowings and long-term bank borrowings, current portion, mature at various dates within one
year. The secured long-term bank borrowings as December 31, 2009 bore weighted average interest rate of 5.751%

Share-based compensation

On January 1, 2008, we adopted our 2008 share incentive plan, which was modified on May 7, 2010, to provide additional incentives to our employees. As of December 31, 2010, there were
outstanding unconditional options to purchase 37,324,760 of our ordinary shares and no outstanding conditional options. The amount of compensation cost recognized for these share options was RMB15.5 million and RMB2.4 million for 2008, respectively,
RMB15.4 million and RMB15,000 for 2009, and RMB1.5 million (US$0.2 million) and nil for 2010, respectively. We allocate share-based compensation expense to selling, general and administrative, and research and development expenses based on the
shares each recipient received and the job responsibility of each recipient.

Taxation and Incentives

Cayman Islands

We are incorporated in the Cayman Islands. Under the current law of the Cayman Islands, we are not subject to income tax.

British Virgin Islands

Under the current laws of the British Virgin
Islands, we are not subject to income tax. In addition, upon any payment of dividends by us, no British Virgin Islands withholding tax is imposed.

Hong Kong

We did not have any assessable profits subject to the
Hong Kong Profits Tax during the years ended December 31, 2008, 2009 and 2010.

Peoples Republic of China

On March 16, 2007, the PRC government enacted the new Enterprise Income Tax law (new EIT law). The
new EIT law and its relevant regulations impose a withholding tax at 10%, unless reduced by a tax treaty, for dividend distributions out of earnings accumulated beginning on January 1, 2008. Undistributed earnings generated prior to
January 1, 2008 are exempt from such withholding tax. Under the China-Hong Kong tax arrangement, a qualified Hong Kong tax resident which is the beneficial owner and holds 25% or more of the equity interest in a PRC-resident
enterprise is entitled to a reduced withholding rate of 5%.

Our subsidiaries in China are also subject to business tax and
related surcharges by various local tax authorities at a rate of 5.0% on revenues generated from providing services. In addition, our subsidiaries in China were generally subject to the standard enterprise income tax rate, which was 33% prior to
December 31, 2007. Shanghai Qi Yue was subject to a preferential tax rate of 15% because it is registered and operating in the Pudong New Area in Shanghai. Shanghai ChemSpec, Taixing ChemSpec and Shanghai Wan Su were subject to a preferential
tax rate of 27% as a result of their conversion into foreign-owned enterprises in 2006. Shanghai ChemSpec, Taixing ChemSpec and Shanghai Wan Su are entitled to an exemption from the enterprise income tax for the first two years and a 50% reduction
in the enterprise income tax in the subsequent three years, starting from its first profit-making year from PRC income tax perspective.

The statutory income tax rate under the new EIT law is 25%. The new EIT law was effective as of January 1, 2008. The new EIT law and its relevant regulations provide a 5-year transition period from
its effective date for those companies which were entitled to a preferential lower tax rate under the then effective tax laws and regulations, as well as grandfathering certain tax holidays. Shanghai Qi Yue was subject to income tax at 18%, 20% and
22% for 2008, 2009 and 2010, respectively, and will be subject to income tax at 24% and 25% for 2011 and 2012, respectively. Some of our subsidiaries are subject to lower enterprise income tax rates due to

Critical Accounting Policies

We prepare our financial statements in conformity with U.S. GAAP, which requires us to make estimates and assumptions that affect our reporting of, among other things, assets and liabilities, contingent
assets and liabilities and net revenues and expenses. We continually evaluate these estimates and assumptions based on the most recently available information, our own historical experiences and other factors that we believe to be relevant under the
circumstances. Since our financial reporting process inherently relies on the use of estimates and assumptions, our actual results could differ from what we expect. This is especially true with some accounting policies that require higher degrees of
judgment than others in their application. We consider the policies discussed below to be critical to an understanding of our audited consolidated financial statements because they involve the greatest reliance on our managements judgment.

Depreciation and amortization

Our long-lived assets primarily include property, plant and equipment. We depreciate and amortize our long-lived assets using the straight-line method over the estimated useful lives of the assets, taking
into account the assets estimated residual values. We estimate the useful lives and residual values at the time we acquire the assets based on our managements knowledge on the useful lives of similar assets and replacement costs of
similar assets having been used for the same useful lives respectively in the market, and taking into account anticipated technological or other changes. If technological changes are to occur more rapidly than anticipated, we may shorten the useful
lives or lower the residual value assigned to these assets, which will result in the recognition of increased depreciation and amortization expense in future periods. There were no significant changes in estimates for the useful lives or salvage
values of our long-lived assets for the years ended December 31, 2008, 2009 and 2010.

Impairment of long-lived assets

We group our long-lived assets for impairment testing at the lowest level for which there are identifiable cash flows that are largely
independent of other asset groups. Our approach in evaluating whether an asset group has identifiable cash flows that are largely independent of the cash flows of other asset groups focuses on the degree to which the Companys total cash flows
(inflows and outflows) depend on the activities of one or more other asset groups of the Company.

We evaluate our long-lived
assets for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Among other considerations, we consider the following factors:



| |  |  | the asset groups ability to continue to generate income from operations and positive cash flow in future periods;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | loss of customers due to the deterioration of specialty chemical industry conditions;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | negative operating cash flows of the asset group;
| | - |  | -------------------------------------------------



| |  |  | increased competition;
| | - |  | ----------------------



| |  |  | a significant decrease in market price of the asset group;
| | - |  | ----------------------------------------------------------



| |  |  | a significant adverse change in the extent or manner in which it is being used or in its physical condition;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | an accumulation of costs significantly in excess of the amount originally expected for its acquisition or construction; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | a current expectation that it is more-likely-than-not that the asset group will be sold or otherwise disposed of significantly before the end of its
previously estimated useful life.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We assess recoverability of our asset groups by comparing the carrying
amount of our asset groups to the estimated undiscounted future cash flows expected to be generated. In determining estimates of future cash flows, we make significant judgment in terms of projection of future cash flows and assumptions. If the
carrying amount of the asset groups exceed the sum of its estimated undiscounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset groups exceed their fair value. We determine the fair
value of our asset groups through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.

For the years ended December 31, 2008, 2009 and 2010, there were no impairment charges recognized on our long-lived assets.

Inventory

At the beginning of every year, the management determines the appropriate level of inventories to maintain on the basis of annual production and operating plans, financial budgets and market conditions.

Our inventories are stated at the lower of cost or market. Cost of work-in-progress and finished goods is comprised of direct
materials, direct labor and related manufacturing overhead based on normal operating capacity. We routinely evaluate the realizability of our inventories in light of market conditions and record write-downs against the cost of inventories. The
evaluation takes into consideration a number of factors including historical and forecasted consumption of our raw materials, our sales contract of finished goods on hand, marketability of our inventories, anticipated change in market selling price,
risk of obsolescence of our inventories due to change in technology or change in physical properties over time and other factors.

Write-down of finished goods were RMB1.1 million, RMB14.7 million and RMB7.3 million (US$1.1 million) during the years ended December 31, 2008, 2009 and 2010, respectively, which are included in
cost of



62

##### Table of Contents

sales. Due to the extremely difficult market situation in 2009, we recorded a provision of RMB 14.7 million to write down our obsolete finished goods. These inventories were related to the
pre-production of certain of our products that can be used in producing agrochemical products on purchase orders that were subsequently cancelled or indefinitely postponed by our customers because of the deterioration in market conditions. We do not
consider our raw materials to be subject to inventory write-down as they are general chemical materials that could be utilized in producing a wide range of our products that can be sold above cost.

Our average inventory turnover period increased from 117 days in 2008 to 176 days in 2009 and to 211 days in 2010. The increase in 2009
was primarily due to the reduced sales in 2009 as a result of the global economic recession and the year-end inventory increase as a result of the change in product mix caused by strong orders for our products used in the electronics chemical
industry. The further increase in 2010 was due to a rise in the production and sales of more complex products, primarily for the electronics end-market.

Allowance for Doubtful Receivables

We maintain allowances for
doubtful receivables for estimated losses resulting from the failure of customers to make required payments. We review the accounts receivable on a periodic basis and make specific allowances when there is doubt as to the collectability of
individual balances. In evaluating the collectability of individual receivable balances, we consider many factors, including the age of the balance, the customers past payment history and current credit-worthiness and current economic trends.
We wrote off nil, nil and RMB0.5 million in customer receivables in 2008, 2009 and 2010, respectively, while recording a reversal of allowance of RMB0.2 million, and RMB 0.1 million in 2008 and 2010, respectively, and recorded bad debt expenses
of RMB0.1 million in 2009.

If our assumptions regarding the financial condition of our customers and their ability and
willingness to pay us are incorrect, our actual bad debt provisions may be higher than estimated, which could result in a charge against our income and a higher level of allowance for doubtful receivables in the future, either of which could have a
material adverse effect on our financial condition and results of operations.

Share-based compensation

On January 1, 2008, we adopted our 2008 share incentive plan, or the plan, which was modified in May 2010, to
provide additional incentives to our employees. The plan provides for the grant of options, restricted shares, and restricted share units. The plan authorizes grants to purchase up to 180,000,000 of our ordinary shares. Stock options granted become
exercisable over four years. We expect to issue new shares to satisfy share option exercises. Under the plan, we granted 13,555,000 unconditional share option awards and 13,555,000 conditional share option awards on January 1, 2008 and
22,700,000 unconditional share option awards and 900,000 conditional share option awards on June 30, 2008 to several of our executives and employees.

The unconditional awards were granted at an exercise price of RMB0.55 per share, vest over four years of continuous service, with 25% of the options vesting on each of the first, second, third and fourth
anniversaries of the grant date, and expire ten years from the grant date.

The conditional awards are granted at an exercise
price equal to 88% of the fair value of our ordinary shares on the respective grant date, vest over four years (provided that service remains continuous during such period) with 25% of the options vesting on each of the first, second, third and
fourth anniversaries of the grant date or, where our audited financial statements for the year immediately preceding each such anniversary are not available on such anniversary, on the date such audited financial statements are issued. The
conditional awards expire ten years from the date of grant. The vesting of conditional options to purchase our ordinary shares is contingent upon (i) our achieving revenue growth of at least 20% in the most recent fiscal year for which audited
financial statements are available prior to each vesting date and (ii) our achieving a compound annual growth rate in sales of at least 20% from (x) the fiscal year immediately preceding the date of awards for which audited



63

##### Table of Contents

financial statements are available, through (y) the most recent fiscal year for which audited financial statements prepared pursuant to U.S. GAAP are available immediately prior to each
vesting date.

On May 7, 2010, our board of directors approved the grant of an aggregate of 24,497,500 unconditional share
options. On the same date, we granted 12,277,500 unconditional share options in exchange for the 12,277,500 conditional share options previously granted under the plan, or the Modification. In addition, on the same date, we granted 12,220,000 share
options to executives and employees who did not participate in the plan.

The Modification was treated as an exchange of the
original conditional share option awards for the unconditional share option awards at the date of the Modification. There was no significant difference between fair value of the new unconditional share option awards and that of the original
conditional option awards immediately before the Modification.

As further described in Note 17 to our audited financial
statements included elsewhere in this annual report, we recognize share-based compensation as a compensation expense in our consolidated statements of income based on the fair value of equity awards on the date of the grant, with the compensation
expense recognized over the period in which the recipient is required to provide service in exchange for the equity award.

The determination of fair value of equity awards such as options requires making complex and subjective judgments about the projected
financial and operating results of the subject company. It also requires making certain assumptions relating to cost of capital, general market and macroeconomic conditions, industry trends, share price volatility of comparable companies, expected
lives of options and discount rates. These assumptions are inherently uncertain. Changes in these assumptions could significantly affect the amount of employee share-based compensation expense we recognize in our consolidated financial statements.
For the purpose of determining the estimated fair value of share options we have already granted, we believe that the expected volatility and the estimated share price of our ordinary shares are the most critical assumptions. Prior and subsequent to
our IPO, since we did not have a trading history at the time the options were issued, and due to lack of sufficient historical trading record, the expected volatility was based on the historical volatilities of comparable publicly traded companies
engaged in a similar industry. The estimated fair value of our ordinary shares on the date of grant prior IPO was determined based on valuation on our ordinary shares also performed by Jones Lang LaSalle Sallmanns Limited, or Sallmanns, an
independent appraiser. Sallmanns determined the fair value of the ordinary shares using the income approach by applying appropriate discount rate to future free cash flows that are based on financial projections developed by the Company. The fair
value of the shares underlying the options we have granted subsequent to our IPO has been based on the closing price of our ADSs listed on the New York Stock Exchange for the trading day prior to the grant date.

The fair value of each option granted was appraised on the date of grant using the lattice option-pricing model incorporating assumptions
with regard to risk-free interest rate, dividend yield, expected term and expected volatility.

The weighted-average grant-date fair value of unconditional share option awards granted
during each of the year ended December 31, 2008 and 2010 was RMB 1.24 and RMB 0.52 (US$0.08) per share. During the years ended December 31, 2008 and 2009, no options were exercised and during the year ended December 31, 2010,
11,670,240 shares were exercised. As of December 31, 2010, there was a total unrecognized compensation cost of RMB6.7 million (US$1.0 million) related to non-vested share options under unconditional share options awards. This cost is expected
to be recognized over the next 3.5 years.

A summary of share option activity under conditional share option awards during
2008, 2009 and 2010 is as follows:

The weighted-average
fair value of conditional share options awards as of December 31, 2009 granted during 2008 was RMB0.73 per share option. During the years ended December 31, 2008, 2009 and 2010, no options were exercised. As of December 31, 2010,
there was no unrecognized compensation cost. The conditional share option awards were cancelled on May 7, 2010.

Based on
grants outstanding at December 31, 2010, and assuming no change in the estimated forfeiture rates, our total share-based compensation expenses for future periods in respect of the equity awards that we have granted to date is expected to be as
follows:

Estimating the value of our share-based compensation expense for future periods requires the input of highly
subjective assumptions, including estimated forfeitures and the price volatility of the underlying shares. We estimate our forfeitures rates based on past employee retention rates and our expectations of future retention rates. We will prospectively
revise our forfeiture rates based on actual history. Our share compensation charges may change based on changes to our actual forfeitures. Our actual share-based compensation expenses may be materially different from our current expectations. In
addition to the subjective assumptions and estimates discussed above, see Item 5. Operating and Financial Review and Prospects. G. Safe Harbor for information regarding the various risks and uncertainties inherent in estimates of this
type.

If the going private transaction described in Item 4. Information on the Company  A. History and
Development of the Company  Going Private Transaction is completed, Merger Sub will merge with and into the Company, with the Company continuing as the surviving company in the merger. At the effective time of the merger, the surviving
company will make to each holder of outstanding vested options to purchase shares under our 2008 share incentive plan an unconditional and irrevocable offer which, if accepted by such holder, will result in such vested options being cancelled and
converted into the right to receive, as soon as reasonably practicable after the effective time, a cash payment equal to the number of shares underlying such option immediately prior to the effective time multiplied by the amount by which US$0.1350
exceeds the exercise price per share of such vested option, without interest and less any applicable withholding taxes.

At the effective time of the merger, the surviving company will make to each holder of
outstanding unvested options to purchase shares under the share incentive plan an unconditional and irrevocable offer which, if accepted by such holder, will result in such unvested options being cancelled and converted into the right to receive, as
soon as reasonably practicable after the effective time, a restricted cash award in the amount equal to the number of shares underlying such option multiplied by the amount by which US$0.1350 exceeds the exercise price per share of such unvested
option. Such restricted cash awards will be subject to the same vesting conditions applicable to the unvested options without giving effect to the merger and any such restricted cash awards will not be transferrable. On the date that the unvested
options would have become vested without giving effect to the merger, such corresponding portion of the restricted cash awards will be delivered to the holder of such restricted cash award, without interest and less any applicable withholding taxes.

Sales. Our sales increased by 31.9% from RMB820.3 million in 2009 to RMB1,082.0 million (US$163.9 million) in 2010, which
reflected (i) an increase in sales generated from commercialized projects from RMB697.4 million in 2009 to RMB979.0 million (US$148.3 million) in 2010; (ii) a decrease in sales generated from pipeline projects from RMB96.4 million in 2009
to RMB86.4 million (US$13.0 million) in 2010; and (iii) a decrease in sales of purchased goods from RMB26.5 million in 2009 to RMB16.7 million (US$2.5 million) in 2010. Our increase in sales during the year was largely due to the upswing in the
demand from our end markets, primarily as a recovery of the global financial crisis.

Cost of sales. Our cost of sales increased by 34.1% from RMB495.6 million in
2009 to RMB664.8 million (US$100.7 million) in 2010 due primarily to increased sales.

Gross profit. As a result
of the foregoing, our gross profit increased 28.5% from RMB324.7 million in 2009 to RMB417.2 million (US$63.2 million) in 2010, while our overall gross profit margin decreased from 39.6% to 38.6%, respectively. The decrease in overall gross margin
was primarily a result of (i) the shift in product mix, and (ii) reduced price in certain products.

Operating
expenses. Our operating expenses increased 32.0% from RMB119.2 million in 2009 to RMB157.3 million (US$23.8 million) in 2010. This increase was primarily due to higher depreciation expenses associated with our new headquarters and research
and development buildings, and consulting expenses associated with SarbanesOxley (SOX) compliance and audit fees.



| |  |  | Selling. Selling expenses decreased 1.0% from RMB11.2 million in 2009 to RMB11.1 million (US$1.7 million) in 2010.
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | General and Administrative. General and administrative expenses increased 11.3% from RMB69.9 million in 2009 to RMB77.8 million (US$11.8
million) in 2010 primarily due to an increase in depreciation expenses associated with the new office building completed in 2009 and fees relating to the SOX compliance consulting work.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Research and Development.Research and development expenses increased by 112.5% from RMB30.9 million in 2009 to RMB65.7 million (US$10.0
million) in 2010. We attribute the increase in our research and development expenses to the increase of material consumption expenses from RMB4.6 million in 2009 to RMB24.5 million in 2010 that were related to an increase of the active R&D
projects to meet the anticipated demand from our customers and the increase in personnel cost from RMB20.2 million in 2009 to RMB28.7 million in 2010.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Other Operating Expenses.Other operating expenses decreased from RMB7.1 million in 2009 to RMB2.7 million (US$0.4 million) in 2010 due
primarily to the decrease in disposal of the fixed assets in 2010.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Other operating income. We
had other operating income of RMB1.6 million (US$0.2 million) in 2010 resulting from income from leases of plant and equipment.

Government grants.The government grants recognized as income increased from RMB1.0 million in 2009 to RMB5.2 million
(US$0.8 million) in 2010.

Income from operations. As a result of the foregoing, we generated income from
operations of RMB266.7 million (US$40.4 million) in 2010, representing an increase of 28.6% as compared to RMB207.5 million of income from operations in 2009.

Interest income. Our interest income decreased from RMB2.3 million 2009 to RMB2.0 million (US$0.3 million) in 2010 because our average cash on deposit in interest-bearing saving
accounts decreased in 2010.

Interest expense. Our interest expense decreased from RMB2.1 million in 2009 to
RMB80, 000 (US$12,000) in 2010, because the average borrowing balance decreased in 2010.

Foreign currency exchange
loss, net. Our net foreign currency exchange loss increased from RMB2.0 million in 2009 to RMB3.2 million (US$0.5 million) in 2010 because the RMB appreciated against the U.S. dollar, as a large percentage of our sales were denominated
in U.S. dollars during this period.

Other income. We had other income of RMB519,000 and RMB400,000 (US$61,000) in
2009 and 2010, respectively.

Earnings before income taxes. Earnings before income taxes increase by 28.8% from
RMB206.0 million in 2009 to RMB265.2 million (US$40.2 million) in 2010.

Income tax expense.Our income tax
expense was RMB39.0 million (US$5.9 million) for 2010, as compared with RMB28.8 million for 2009. The PRC statutory tax rate for 2010 and 2009 was 25%. The effective tax rate of 14.7% in 2010 was mainly due to the effect of a tax holiday
amounting to RMB35.5 million which reduced our effective tax rate by 13.4%, partially offset by the effect of tax rate differential expenses on PRC operations amounting to RMB4 million which increased our effective tax rate by 1.5%.The effective tax
rate of 14.0% in 2009 was mainly due to the effect of a tax holiday amounting to RMB26.0 million which reduced our effective tax rate by 12.6%.

Net income. As a result of the foregoing, we had net income of RMB226.2 million (US$34.3 million) in 2010, compared to net income of RMB177.2 million in 2009, an increase of 27.7%.

Net income attributable to noncontrolling interests. Net income attributable to noncontrolling interests
amounted to RMB4.7 million and RMB685,000 (US$104,000) in 2009 and 2010, respectively, attributable to (i) 20% ownership interest in Huajing Company, which was held by Mr. Xuhua Ren; (ii) the 48.3% ownership interest in Kangpeng Nong Hua
through November 2009, which was held by Mr. Zhiyan Shen, Ms. Yunfen Fan, Dr. Yunhong Tang and Kang Qi Investment Company, or Kang Qi, respectively; (iii) the 20% ownership interest in Jiangsu Wei Er through November 2009, which was held by Mr.
Zhiyan Shen and Ms. Yunfen Fan; and (iv) the 8% ownership interest in Binhai Kangjie through March 2011, which was held by Mr. Yunxiang Wang.

Net income attributable to the Company. As a result of the foregoing, we had net income attributable to the Company of RMB225.5 million (US$34.2 million) in 2010, compared to RMB172.4
million 2009, an increase of 30.8%.

Year ended December 31, 2009 compared to year ended December 31, 2008

Sales. Our sales decreased by 13.0% from RMB942.5 million in 2008 to RMB820.3 million in 2009, which reflected (i) a
decrease in sales generated from commercialized projects from RMB801.5 million in 2008 to RMB697.4 million in 2009; (ii) an increase in sales generated from pipeline projects from RMB59.2 million in 2008 to RMB96.4 million in 2009; and
(iii) a decrease in sales of purchased goods from RMB81.8 million in 2008 to RMB26.5 million in 2009. Our decrease in sales during the year was due largely to weak demand in our end markets, primarily as a result of the global financial crisis.

Cost of sales. Our cost of sales decreased by 9.7% from RMB548.5 million in 2008 to RMB495.6 million in 2009
due primarily to reduced sales in electronic chemicals in 2009, particularly in the first quarter, and reduced sales in agrochemicals in the third and fourth quarters of 2009 caused by the extremely difficult market situation in 2009, partially
offset by a provision of RMB 14.7 million to write down the value of some of our obsolete inventories at the end of 2009.

Gross profit. As a result of the foregoing, our gross profit decreased 17.6% from RMB393.9 million in 2008 to RMB324.7
million in 2009, while our overall gross profit margin decreased from 41.8% to 39.6%, respectively. The decrease in overall gross margin was primarily a result of (i) reduced sales in electronic chemicals in 2009 and (ii) reduced sales and
gross margin for our agrochemical products due to severe competition caused by the global economic slowdown.

##### Table of Contents

Operating expenses. Our operating expenses increased 18.6% from RMB100.5
million in 2008 to RMB119.2 million in 2009. This increase was primarily due to higher personnel salaries for experienced senior level employees, higher depreciation expenses associated with the construction of our new headquarters and research and
development buildings, and other consulting and audit fees associated with being a publicly-listed company.



| |  |  | Selling. Selling expenses decreased 5.5% from RMB11.9 million in 2008 to RMB11.2 million in 2009 due primarily to a decrease in sales of
products for which we bear shipping costs.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | General and Administrative. General and administrative expenses increased 18.5% from RMB58.9 million in 2008 to RMB69.9 million in 2009
primarily due to an increase in the size of our administrative staff to support the growth of our operations, an increase in depreciation expenses associated with the new office building completed in 2009, and fees relating to the SOX compliance
consulting work. In addition, in 2009, we recognized a share-based compensation expense of RMB11.8 million related to general and administrative expenses in connection with grants made under our 2008 share incentive plan.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Research and Development. Research and development expenses increased by 12.5% from RMB27.5 million in 2008 to RMB30.9 million in 2009. We
attribute the increase in our research and development expenses to an increase in personnel expenses of RMB4.8 million, as a result of the expansion of our research and development staff, offset in part by a decrease in the raw materials used in our
research and development activities from RMB7.3 million in 2008 to RMB4.6 million in 2009. We were able to reduce the amount of raw materials used in research and development activities because of reduced internal test failure rates when conducting
experiments.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Other Operating Expenses. Other operating expenses increased from RMB2.2 million in 2008 to RMB7.1 million in 2009 due primarily to disposal of
fixed assets in 2009.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------

Other operating income. We had other operating income of RMB1.0 million
in 2009 resulting from income from leases of plant and equipment.

Government grants.The government grants
recognized as income increased from RMB50,000 in 2008 to RMB1.0 million in 2009.

Income from operations. As a result
of the foregoing, we generated income from operations of RMB207.5 million in 2009, representing a decrease of 29.6% as compared to RMB294.5 million of income from operations in 2008.

Interest income. Our interest income increased from RMB2.1 million in 2008 to RMB2.3 million in 2009 because our total cash on
deposit in interest-bearing saving accounts and the relevant interest rates increased between these periods.

Interest
expense. Our interest expense decreased from RMB2.7 million in 2008 to RMB2.1 million in 2009, due to (i) a decrease in bank borrowings outstanding from RMB65.0 million as of December 31, 2008 to RMB10.0 million as of
December 31, 2009 and (ii) a decrease in the weighted average interest rate of our bank borrowings in 2009.

Foreign currency exchange loss, net. Our net foreign currency exchange loss decreased significantly from RMB9.5 million in
2008 to RMB2.0 million in 2009 because starting from mid 2008 our sales were no longer denominated in Euro and we were not subject to the exchange risk of the Euro against the U.S. dollar.

Other income. We had other income of RMB82,000 and RMB519,000 (US$76,000) in 2008 and 2009, respectively.

Earnings before income taxes. Earnings before income taxes decreased by 27.6%
from RMB284.4 million in 2008 to RMB206.0 million in 2009.

Income tax benefit (expense). Our income tax expense
was RMB28.8 million for 2009, as compared with an income tax benefit of RMB32.2 million for 2008. The PRC statutory tax rate for 2009 and 2008 was 25%. Our income tax expense in 2009 was reduced by effect of a tax holiday amounting to RMB26.0
million which reduced our effective tax rate by 12.6%. In addition, PRC dividend withholding tax was only accrued for certain undistributed earnings of our PRC subsidiaries as we plan to indefinitely reinvest a portion of the undistributed earnings
in the PRC. These attributed to an overall effective tax rate of 14.0% in 2009. The effective tax benefit rate of 11.3% in 2008 was mainly due to (i) a reinvestment tax refund of RMB16.3 million; (ii) an income tax refund of RMB42.5
million; and (iii) effect of a tax holiday amounting to RMB61.9 million which reduced our effective tax rate by 5.7%, 14.9% and 21.8%, respectively. In addition, the new PRC corporate income tax law imposed dividend withholding tax on earnings
generated since January 1, 2008, which increased our 2008 income tax expense by RMB13.9 million and the related tax effect was 4.9%.

Net income. As a result of the foregoing, we had net income of RMB177.2 million in 2009, compared to net income of RMB316.7 million in 2008, a decrease of 44.0%.

Net income attributable to noncontrolling interests. Net income attributable to noncontrolling interests amounted to RMB4.3
million and RMB4.7 million in 2008 and 2009, respectively, attributable to (i) the 40% ownership interest in Huajing Company before April 2008 and the 20% ownership interest after then, which was held by Mr. Xuhua Ren; (ii) the 48.3%
ownership interest in Kangpeng Nong Hua from October 2008 through November 2009, which was held by Mr. Zhiyan Shen, Ms. Yunfen Fan, Dr. Yunhong Tang and Kang Qi, respectively; (iii) the 20% ownership interest in Jiangsu Wei Er
from February 2008 through November 2009, which was held by Mr. Zhiyan Shen and Ms. Yunfen Fan; and (iv) the 8% ownership interest in Binhai Kangjie, which was held by Mr. Yunxiang Wang.

Net income attributable to the Company. As a result of the foregoing, we had net income attributable to the Company of
RMB172.4 million in 2009, compared to RMB312.4 million in 2008, a decrease of 44.8%.

B. Liquidity and Capital Resources

Liquidity and Capital Resources

Our primary sources of liquidity have historically been cash generated from our operations. Historically, we were able to finance a significant portion of our operations and capital investments from our
cash flows from operations. As of December 31, 2010, we had approximately RMB98.7 million (US$15.0 million) in cash. Our cash generally consists of cash on hand and demand deposits. We require cash to fund our ongoing business needs,
particularly salary and benefits and material costs and expenses. Other cash needs include primarily the working capital for our daily operations and manufacturing activities, the purchase of equipment for our manufacturing facilities and
expenditures related to the expansion of our manufacturing and research and development facilities. As of December 31, 2010, we had approximately RMB25 million (US$3.8 million) in short-term bank borrowings and long-term bank borrowing, current
portion, with a weighted average interest rate of 5.27% per annum. The amount of unused credit facilities available associated with bank borrowings as of December 31, 2010 amounted to RMB75.0 million (US$11.4 million). Our short-term bank
borrowings and long-term bank borrowings, current portion, are due in 2011. These facilities contain no specific renewal terms or any requirement for the maintenance of financial covenants. We have traditionally negotiated the renewal of facilities
shortly before they mature although, no assurance can be made that we will be able to continue successfully re-negotiate the renewal of these facilities in the future. As of December 31, 2010, we had no long-term bank borrowings.

Cash decreased from RMB351.1 million as of December 31, 2009 to RMB98.7 million (US$15.0 million) as of December 31, 2010. The
net cash outflow was primarily due to cash paid for capital expenditures of approximately RMB241.2 million (US$36.5 million) in 2010.

We conduct all of our business through our consolidated subsidiaries incorporated in China.
We rely on dividends paid by consolidated subsidiaries for the cash needs of Chemspec International Limited, including the funds necessary to pay any dividends and other cash distributions to our shareholders, to service any debt we may incur and to
pay our operating expenses. The payment of dividends by entities established in China is subject to limitations. Any limitations on the ability of our PRC subsidiaries to transfer funds to us could materially and adversely limit our ability to grow,
make investments or acquisitions that could be beneficial to our business, pay dividends and otherwise fund and conduct our business. See Item 3. Key InformationD. Risk FactorsRisks Related to Doing Business in ChinaWe rely
on dividends paid by our subsidiaries for our cash needs, and any limitation on the ability of our subsidiaries to make payments to us could have a material adverse effect on our ability to conduct our business.

We expect to continue to generate positive operating cash flow in 2011. During 2010, we generated net cash from operating activities
which supported part of the investing and financing activities. For the year 2011, the Company expects to incur no more than RMB200 million in capital expenditures pursuant to the going private transaction merger agreement that was filed with SEC on
March 21, 2011. See Item 4. Information on the CompanyA. History and Development of the CompanyGoing Private Transaction. Based on current credit conditions in China and preliminary discussions with our local banks, we
do not believe we will encounter any problems in increasing our borrowings if the need arises.

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

Operating Activities

Net cash provided by operating activities decreased from RMB209.3 million for the year ended December 31, 2009 to
RMB96.2 million (US$14.6 million) in 2010. This decrease was the result of an increase in cash payment for building-up of inventory at the year-end due to strong orders for our products used in production of electronics chemicals, as our products in
this field are technically highly complex and involve a long in-house production cycle.

Net cash provided by operating
activities decreased from RMB289.7 million for the year ended December 31, 2008 to RMB209.3 million for the year ended December 31, 2009. This decrease was the result of (i) an increase in cash payment for build-up of inventory at the
year-end due to strong orders for our products used in production of electronics chemicals to be delivered in the first quarter of 2010, as our products in this field are technically highly complex and involve a long in-house production cycle;
(ii) a decrease in cash collected from our customers due to the reduced sales, especially in the fourth quarter of 2009; and (iii) an increase in cash payment for operating expenses due to the expansion of our business.

Investing Activities

Net cash used in investing activities amounted to RMB112.2 million, RMB257.9 million and RMB254.7 million (US$38.6 million) in 2008, 2009 and 2010, respectively. Net cash used in investing activities

reflects capital expenditures made in connection with the expansion and upgrade of our research and development and manufacturing facilities, and purchase of land use rights. These capital
expenditure cash outflows were RMB127.8 million in 2008, RMB227.7 million in 2009 and RMB241.2 million (US$36.5 million) in 2010. In addition, we made payments of RMB17.5 million, RMB4.0 million and RMB4.5 million (US$0.7 million) for land use
rights in 2008, 2009 and 2010, respectively, in connection with securing the land for construction of our new facilities. We expect to incur no more than RMB200 million in capital expenditures in 2011 pursuant to the going private transaction merger
agreement that was filed with SEC on March 21, 2011. See Item 4. Information on the CompanyA. History and Development of the CompanyGoing Private Transaction.

Financing Activities

Net cash used in financing activities amounted to RMB54.2 million and RMB92.6 million (US$14.0 million) in 2008 and 2010 respectively, and net cash provided by financing activities amounted to RMB219.1
million in 2009. Cash used in financing activities primarily consists of dividends paid to shareholders, repayment of bank loans, acquisition of additional equity interest in subsidiary, repurchase of ordinary shares from the open market and
repayment of borrowings from related parties,. Cash provided from financing activities primarily consists of proceeds from bank loans, proceeds from borrowings from related parties, and proceeds of approximately RMB389.0 million (US$57.0 million)
from our initial public offering in June 2009. We did not declare any dividends in 2008. One of our subsidiaries made a cash distribution of RMB 2.5 million to our noncontrolling interest holders in June 2009. On March 7, 2010, we declared
the 2009 dividend of US$0.003 per ordinary share (US$0.18 per ADS) to shareholders of record as of March 31, 2010 with payment date of April 21, 2010. We do not expect to declare or pay any further dividends prior to the proposed merger
which would result in us becoming a privately-held company, and under the terms of the going private transaction merger agreement, are prohibited from doing so without Halogen Limiteds prior written approval. See Item 4. Information on
the CompanyA. History and Development of the CompanyGoing Private Transaction.

Capital Expenditures

Our capital expenditures are incurred primarily in connection with (i) purchases of property, plant and equipment and construction of
our head office, research and development center and production facilities, (ii) investment in equipment, technology and operating systems, and (iii) capitalized interest. Our capital expenditures were RMB163.1 million, RMB342.7 million
and RMB244.1 million (US$37.0 million) in 2008, 2009 and 2010, respectively. Our primary planned capital expenditures for 2011 are for expansion of our manufacturing capacity in China, maintenance of our existing facilities, and enhancement of our
research and development capabilities in China. See Item 4. Information on the CompanyB. Business OverviewHeadquarters and Facilities. We expect to incur no more than RMB200 million in capital expenditures in 2011 pursuant to
the going private transaction merger agreement that was filed with SEC on March 21, 2011. See Item 4. Information on the CompanyA. History and Development of the CompanyGoing Private Transaction.

Inventories and Receivables

Inventories and receivables are two principal components of our working capital, particularly during periods when sales increase. Accordingly, control of inventories and receivables are key aspects of our
operations.

Our average inventory turnover period increased from 117 days in 2008 to 176 days in 2009 and to 211 days in
2010. The increase in 2009 was primarily due to the reduced sales in 2009 as a result of the global economic recession and the year-end inventory increase as a result of the change in product mix caused by strong orders for our products used in the
electronics chemical industry. The further increase in 2010 was due to a rise in the production and sales of more complex products, primarily for the electronics end-market.

We sell to our principal customers on an open account basis, allowing credit terms of
between 30 and 120 days, with most payments made within 90 days. The average collection days for our accounts receivable was 35 days in 2008, 56 days in 2009 and 37 days in 2010. The increase of the average collection days in 2009 was mainly
due to the difficult global economic condition which caused the payment patterns of some of our customers to change. With the recovery of global business environment in 2010, the payment pattern came back to the 2008 level. Bad debt expense
accounted for less than 1% of our sales in each of 2008, 2009 and 2010.

B. Compensation

Cash Compensation

In
2010, the aggregate cash compensation to our executive officers, including all the directors, was RMB5.4 million (US$0.8 million). For options granted to officers and directors, see 2008 Share Incentive Plan.

2008 Share Incentive Plan

We have adopted our 2008 share incentive plan, as modified in 2010, to attract and retain the best available personnel, provide additional
incentives to our employees, directors and consultants, and promote the success of our business. The 2008 share incentive plan provides for the grant of options, restricted shares, and restricted share units, collectively referred to as
awards. Our board of directors has authorized the issuance of up to 180,000,000 ordinary shares upon exercise of awards granted under our 2008 share incentive plan.

Plan Administration. Our compensation committee, or prior to such committees formation, our board or directors, will
administer the 2008 share incentive plan. The committee or the full board of directors, as appropriate, will determine the participants to receive awards, the type and number of awards to be granted, and the terms and conditions of each award grant.

Award Agreements. Awards granted under our 2008 share incentive plan are evidenced by an award agreement that sets
forth the terms, conditions and limitations for each grant, which may include the term of the award, the provisions applicable in the event that the grantees employment or service terminates, and our authority to unilaterally or bilaterally
amend, modify, suspend cancel or rescind the award.

Transfer Restrictions. The right of a grantee in an award granted
under our 2008 share incentive plan may not be transferred in any manner by the grantee other than by will or the laws of succession and, with limited exceptions, may be exercised during the lifetime of the grantee only by the grantee.

Option Exercise. The term of options granted under the 2008 share incentive plan may not exceed ten years from the date of grant.
The consideration to be paid for our ordinary shares upon exercise of an option or purchase of shares underlying the option may include cash, check or other cash-equivalent, ordinary shares, consideration received by us in a cashless exercise, or
any combination of the foregoing methods of payment.

Acceleration upon a Change of Control. If a change of control of
our company occurs, (i) the compensation committee may determine that any outstanding unexercisable, unvested or lapsable awards shall automatically be deemed exercisable, vested and not subject to lapse immediately prior to the event
triggering the change of control and (ii) the compensation committee may cancel such awards for fair value, provide for the issuance of substitute awards or provide that for a period of at least 15 days prior to the event triggering the change
of control, such options shall be exercisable and that upon the occurrence of the change of control, such options shall terminate and be of no further force and effect.

Termination and Amendment. Unless terminated earlier, our 2008 share incentive plan will expire after ten years. Our board of directors has the authority to amend or terminate our 2008 share
incentive plan subject to shareholder approval to the extent necessary to comply with applicable laws. Shareholders approval is required for any amendment to the 2008 share incentive plan that (i) increases the number of ordinary shares
available under the 2008 share incentive plan or changes the maximum number of shares for which awards may be granted to any participant or, (ii) diminish any of the rights of the participant under any award previously granted to such
participant under the plan without such participants consent.

parties. In November 2009, we acquired 100% of the equity interest of Jiangsu Kangpeng Nong Hua for RMB25 million in cash.

In
2008, we purchased goods, consisting of chemicals produced by Kangpeng Nong Hua, from Kangpeng Nong Hua totaling RMB26.2 million, respectively. We then resell these goods to customers in the pharmaceutical and agrochemical industries with a 1% to 7%
mark-up. In 2008, we also made sales of goods produced by our newly acquired subsidiary Jiangsu Wei Er to Kangpeng Nong Hua in the amount of RMB32.0 million consisting of raw materials for its manufacturing of goods to be sold in the open market and
to us. We believe these transactions were conducted in the ordinary course of business on terms comparable to those with unrelated third parties.

We made non-interest bearing advances to Kangpeng Nong Hua in the amount of RMB28.4 million in 2008. We made these advances to support Kangpeng Nong Huas operating activities and repaid these
advances in full in 2008.

We made trade advances to Kangpeng Nong Hua in the amount of RMB23.6 million in 2007. These trade
advances to Kangpeng Nong Hua were prepayments for the purchase of goods. The full amount of the prepayments has been utilized in the purchase of raw materials in 2008.

We also received a non-interest bearing advance from Kangpeng Nong Hua in the amount of RMB14.4 million in 2008. We repaid this advance in full as of June 30, 2008.

Leasing Transactions with Shanghai Ambiopharm

Shanghai Ambiopharm Inc., or Ambiopharm, engages in the manufacture of advanced pharmaceutical intermediates. Dr. Jianghua Yang indirectly owns 70.5% of Ambiopharm.

We lease plant and equipment to Ambiopharm, which uses these equipment and facilities for production of chemicals. The leases are for
terms of two years with total annual rents per year of RMB0.9 million. In 2009 and 2010, we recorded lease income from Ambiopharm in the amount of RMB0.9 million and RMB0.9 million (US$0.1 million), respectively.

We lease certain equipment from Ambiopharm for use in our chemical production operations. The initial lease term was two years,
commencing in July 2008, and was renewed for an additional two-year period in June 2010, with total annual rents per year of RMB100,000. In 2008, 2009 and 2010, we incurred lease expenses in the amount of RMB42,000, RMB100,000 and RMB100,000
(US$15,000), respectively.

Central Glass Chemspec Co., Ltd, or Central Glass Chemspec, is our affiliate. Central Glass Company Limited, or Central Glass, is the
controlling shareholder of Central Glass Chemspec. In 2009 and 2010, we made sales of goods to Central Glass in the amount of RMB4.0 million and RMB3.7 million (US$0.6 million), respectively.

Non-Interest Bearing Borrowings from Related Parties

In 2006, we borrowed
US$9.7 million from Wise Lion Limited as part of our reorganization to finance our acquisition of the operating subsidiaries. Wise Lion Limited is one of our shareholders, and Wise Lion Limited is beneficially owned by our director, Dr. Jianhua
Yang, and his wife Ms. Yuezhen Cha. We repaid US$1.7 million and US$2.5 million to Wise Lion Limited in 2006 and 2007, respectively. The borrowing was repaid in full in September 2009.

We borrowed RMB50,000 in 2007 from Dr. Jianhua Yang, his wife Ms. Yuezhen Cha and his son Mr. Chongbo Yang, or the Yang
Family. As of December 31, 2009 and 2010, the balance of our amount due to the Yang Family was RMB59,000 (US$9,000).

In
2008 and 2009, we borrowed RMB6.0 million and RMB6.0 million (US$0.9 million) from Kang Qi which is a subsidiary owned by the Yang Family. The borrowings were repaid in full in February 2008 and in April 2009, respectively.

Non-Interest Advances to Related Parties

In 2008, we advanced RMB2.5 million to the noncontrolling shareholder of Kangpeng Nong Hua, Mr. Zhiyan Shen. This amount was repaid in full in January 2009.

Non-Interest Bearing Borrowings by Jiangsu Wei Er from Related Parties

In February 2008, we paid a cash consideration of RMB4.0 million (US$0.6 million) to acquire an 80% ownership stake in Jiangsu Wei Er, which had been one of our long-term suppliers and produces a number
of specialty chemicals used in increasingly popular agrochemical products currently on the market. In November 2009, we acquired the remaining noncontrolling shares of Jiangsu Wei Er for RMB41.0 million (US$6.0 million) in cash. In 2008, Jiangsu Wei
Er borrowed RMB49.3 million and RMB5 million from Kangpeng Nong Hua and Kang Qi, respectively. These borrowings were repaid in full as of December 31, 2008.

Non-Interest Bearing Borrowings by Kangpeng Nong Hua from Related Parties

Prior to October 8, 2008, Kangpeng Nong Hua borrowed RMB14.3 million, RMB0.7 million, RMB0.2 million and RMB3,000, which were
non-interest bearing, from Kang Qi, the Yang Family, Mr. Zhiyan Shen and Ms. Yunfen Fan, respectively. The advances from the Yang Family, Mr. Zhiyan Shen and Ms. Yunfen Fan were repaid in full as of December 31, 2009. We
repaid RMB2,958,000 in 2008 after the acquisition, RMB2,769,000 and RMB4,000,000 in 2009 and 2010, respectively.

|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 and Administrative Proceedings

We are currently not a party to any other material legal or administrative proceedings, and we are not aware of threatened material legal or administrative proceedings against us. We may from time to time
become a party to various legal or administrative proceedings arising in the ordinary course of our business.

Dividend Policy

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

We did not declare any dividends in 2008. One of our subsidiaries made a cash distribution of RMB
2.5 million to our noncontrolling shareholders in June 2009. On March 7, 2010, we declared a 2009 dividend of US$0.003 per ordinary share (US$0.18 per ADS) to shareholders of record as of March 31, 2010 with payment date of
April 21, 2010. In the future, at the determination of our board of directors, we may from time to time pay a cash dividend to our shareholders equal to an aggregate of no less than 10% of our net income determined in accordance with U.S. GAAP
for each such year. The payment of any such dividend will depend upon our profitability and will be subject to the discretion of our management and the approval of our board of directors. Aside from the payment of such dividends, we currently intend
to retain the remainder of our available funds and any future earnings to operate and expand our business.

Notwithstanding
the above paragraph, we do not expect to declare or pay any further dividends prior to the proposed merger which would result in us becoming a privately-held company, and under the terms of the going private transaction merger agreement, are
prohibited from doing so without Halogen Limiteds prior written approval. See Item 4. Information on the CompanyA. History and Development of the CompanyGoing Private Transaction.

In addition, our ability to pay dividends depends substantially on the payment of dividends to us by our operating subsidiaries in China.
Each of the operating subsidiaries may pay dividends only out of its accumulated distributable profits, if any, determined in accordance with its articles of association, and the accounting standards and regulations in China. Each of our PRC
subsidiaries, including wholly foreign-owned enterprises, or WFOEs, and joint venture enterprises is also required to set aside at least 10% of its after-tax profit based on PRC accounting standards each year to its general reserves or statutory
capital reserve fund until the aggregate amount of such reserves reaches 50% of its respective registered capital. Our statutory reserves are not distributable as loans, advances or cash dividends. In addition, if any of our PRC subsidiaries 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. Any limitation on the payment of dividends by our subsidiaries could materially and adversely limit
our ability to grow, make investments or acquisitions that could be beneficial to our businesses, pay dividends and otherwise fund and conduct our businesses. See Item 3. Key InformationD. Risk FactorsRisks Related to Doing
Business in ChinaWe rely on dividends paid by our subsidiaries for our cash needs, and any limitation on the ability of our subsidiaries to make payments to us could have a material adverse effect on our ability to conduct our business.

In addition, under a new PRC tax law that became effective in January 2008, dividends paid from our PRC subsidiaries to us
through our Hong Kong subsidiary will be subject to a withholding tax at a rate of 5%. The withholding tax on dividends may be exempted or reduced by the State Council of the PRC. Furthermore, the



85

##### Table of Contents

ultimate tax rate will be determined by treaty between the PRC and the tax residence of the holder of the PRC subsidiary. See Item 5. Operating and Financial Review and
ProspectsTaxation and IncentivesPeoples Republic of China, and Item 10. Additional Information. E. TaxationPeoples Republic of China Taxation. We are actively monitoring the withholding tax and are
evaluating appropriate organizational changes to minimize the corresponding tax impact.

If we pay any dividends, the
depositary will distribute such payments to our ADS holders to the same extent as holders of the corresponding numbers of our ordinary shares, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder. Cash
dividends on our ordinary shares, if any, will be paid in U.S. dollars.

B. Significant Changes

Except as disclosed elsewhere in this annual report, we have not experienced any significant changes since the date of our audited
consolidated financial statements included elsewhere in this annual report.

C. Material Contracts

D. Exchange Controls

Pursuant to the Foreign Exchange Administration Rules promulgated on January 29, 1996 and amended on January 14, 1997 and August 5, 2008, and various regulations issued by the SAFE and
other relevant PRC government authorities, RMB is freely convertible only with respect to current account items, such as trade- related receipts and payments, interest and dividends. Capital account items, such as direct equity investments, loans
and repatriations of investments, require the prior approval of the SAFE or its local branches for conversion of RMB into foreign currency, such as U.S. dollars, and remittance of the foreign currency outside the PRC.



87



---

##### Table of Contents

Payments for transactions that take place within the PRC must be made in RMB. Unless
otherwise approved, PRC companies must repatriate foreign exchange payments received from abroad. Foreign-invested enterprises may retain foreign exchange in accounts with designated foreign exchange banks subject to a cap set by the SAFE or its
local counterpart. Unless otherwise approved, domestic enterprises must convert all of their foreign exchange receipts into RMB.

Pursuant to the SAFEs Notice on Relevant Issues Concerning Foreign Exchange Administration for PRC Residents to Engage in Financing and Inbound Investment via Overseas Special Purpose Vehicles, or
the SAFE Circular No. 75, issued on October 21, 2005, (i) a PRC resident must register with the local SAFE branch before establishing or controlling an overseas special purpose vehicle, or SPV, for the purpose of obtaining overseas
equity financing using the assets of or equity interests in a domestic enterprise; (ii) when a PRC resident contributes the assets of or its equity interests in a domestic enterprise into an SPV, or engages in overseas financing after
contributing assets or equity interests into an SPV, such PRC resident must register his or her interest in the SPV and any subsequent change thereto with the local SAFE branch; and (iii) when the SPV undergoes a material event, such as a
change in share capital, merger and acquisition, share transfer or exchange, spin-off or long-term equity and debt investment, the PRC resident must, within 30 days from the occurrence of such event, register such change with the local SAFE branch.
On May 29, 2007, the SAFE issued relevant guidance to its local branches for the implementation of the SAFE Circular No. 75. This guidance standardizes more specific and stringent supervision on the registration requirement relating to the
SAFE Circular No. 75 and further requests PRC residents holding any equity interests or options in SPVs, directly or indirectly, controlling or nominal, to register with the SAFE.

Our beneficial owners who are or may be considered PRC residents have registered with the local SAFE branch as required under the SAFE
Circular No. 75, and the required amendment to such registrations have been completed. See Item 3. Key InformationD. Risk FactorsRisks Related to Doing Business in ChinaRecent PRC regulations relating to the
establishment of offshore special purpose companies by PRC residents may subject our PRC resident shareholders to personal liability, limit our ability to inject capital into our PRC subsidiaries, limit our PRC subsidiaries ability to
distribute profits to us, or otherwise adversely affect us.

E. Taxation

Cayman Islands Taxation

The Cayman Islands currently levy 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. No Cayman Islands stamp duty will be payable unless an instrument is executed in, brought to, or
produced before a court of the Cayman Islands. The Cayman Islands are not parties to any double-tax treaties which are applicable to payments made to or by our Company. There are no exchange control regulations or currency restrictions in the Cayman
Islands.

Peoples Republic of China Taxation

The newly enacted PRC Enterprise Income Tax Law, or the EIT Law, and the implementation regulations for the EIT Law issued by the PRC State Council, became effective as of January 1, 2008. The EIT
Law provides that enterprises established outside of China whose de facto management bodies are located in China are considered resident enterprises and are generally subject to the uniform 25% enterprise income tax rate as
to their worldwide income. On December 6, 2007, the State Council adopted the Regulation on the Implementation of PRC Enterprise Income Tax Law, effective as of January 1, 2008, which defines the de facto management body as an
establishment that has substantial management and control over the business, personnel, accounts and properties of an enterprise. Currently no interpretation or application of the new EIT Law and its implementing rules is available for non-Chinese
enterprise or group enterprise controlled entity. Therefore, although substantially all of our operational management is currently based in the PRC, it is unclear whether PRC tax authorities would require (or permit) us to be treated as a PRC
resident enterprise.



88



---

##### Table of Contents

Under the EIT Law and implementation regulations issued by the State Council, PRC income tax
at the rate of 10% is applicable to dividends payable to investors that are non-resident enterprises (and that do not have an establishment or place of business in the PRC, or that have such establishment or place of business but the
relevant income is not effectively connected with the establishment or place of business) to the extent such dividends have their sources within the PRC. Similarly, any gain realized on the transfer of ADSs or shares by such investors is also
subject to 10% PRC income tax if such gain is regarded as income derived from sources within the PRC. However, under a new PRC tax law that became effective in January 2008 and the Arrangement between the PRC and the Hong Kong Special
Administrative Region on the Avoidance of Double Taxation and Prevention of Fiscal Evasion, or the China-Hong Kong tax arrangement, which became effective on January 1, 2007, dividends from our PRC subsidiaries paid to us through our Hong
Kong subsidiary are subject to a withholding tax at a rate of 5%. If we are considered a PRC resident enterprise, it is unclear whether dividends we pay with respect to our ordinary shares or ADSs, or the gain you may realize from the
transfer of our ordinary shares or ADSs, would be treated as income derived from sources within the PRC and would be subject to PRC tax. It is also unclear whether, if we are considered a PRC resident enterprise, holders of our ordinary
shares or ADSs might be able to claim the benefit of income tax treaties entered into between China and other countries.

United States
Federal Income Taxation

The following summary describes the material United States federal income tax consequences of the
ownership of our ordinary shares or ADSs as of the date hereof. The discussion is applicable to United States Holders (as defined below) who hold our ordinary shares or ADSs as capital assets. As used herein, the term United States
Holder means a holder of an ordinary share or ADS that is for United States federal income tax purposes:



| |  |  | an individual citizen or resident of the United States;
| | - |  | -------------------------------------------------------



| |  |  | a corporation (or other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the
United States, any state thereof or the District of Columbia;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an estate the income of which is subject to United States federal income taxation regardless of its source; or
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | a trust if it (1) is subject to the primary supervision of a court within the United States and one or more United States persons have the
authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

This summary does not represent a detailed description of the United States federal income tax consequences applicable to you if you are
subject to special treatment under the United States federal income tax laws, including if you are:



| |  |  | a dealer in securities or currencies;
| | - |  | -------------------------------------



| |  |  | a financial institution;
| | - |  | ------------------------



| |  |  | a regulated investment company;
| | - |  | -------------------------------



| |  |  | a real estate investment trust;
| | - |  | -------------------------------



| |  |  | an insurance company;
| | - |  | ---------------------



| |  |  | a tax-exempt organization;
| | - |  | --------------------------



| |  |  | a person holding our ordinary shares or ADSs as part of a hedging, integrated or conversion transaction, a constructive sale or a straddle;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a trader in securities that has elected the mark-to-market method of accounting for your securities;

##### Table of Contents

| |  |  | a person liable for alternative minimum tax;
| | - |  | --------------------------------------------



| |  |  | a person who owns or is deemed to own 10% or more of our voting stock;
| | - |  | ----------------------------------------------------------------------



| |  |  | a partnership or other pass-through entity for United States federal income tax purposes (or hold your ordinary shares or ADSs through a partnership or
other pass-through entity); or
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a person whose functional currency is not the United States dollar.

The discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended, or the Code, and regulations, rulings
and judicial decisions thereunder as of the date hereof, and such authorities may be replaced, revoked or modified so as to result in United States federal income tax consequences different from those discussed below. In addition, this summary is
based, in part, upon representations made to us by the depositary and assumes that the deposit agreement, and all other related agreements, will be performed in accordance with their terms.

If a partnership holds ordinary shares or ADSs, the tax treatment of a partner will generally depend upon the status of the partner and
the activities of the partnership. If you are a partner of a partnership holding our ordinary shares or ADSs, you should consult your tax advisors.

This summary does not contain a detailed description of all the United States federal income tax consequences to you in light of your particular circumstances nor does it address any United States federal
tax laws other than United States federal income tax laws. If you are considering the purchase, ownership or disposition of our ordinary shares or ADSs, you should consult your own tax advisors concerning the United States federal tax
consequences to you in light of your particular situation as well as any consequences arising under the laws of any other taxing jurisdiction.

The U.S. Treasury has expressed concerns that intermediaries in the chain of ownership between the holder of an ADS and the issuer of the security underlying the ADS may be taking actions that are
inconsistent with the claiming of foreign tax credits for United States Holders of ADSs. Such actions would also be inconsistent with the claiming of the reduced rate of tax, described below, applicable to dividends received by certain non-corporate
holders. Accordingly, the analysis of the creditability of PRC taxes, if any, and the availability of the reduced tax rate for dividends received by certain non-corporate holders, each described below, could be affected by actions taken by
intermediaries in the chain of ownership between the holder of an ADS and our company.

ADSs

If you hold ADSs, for United States federal income tax purposes, you generally will be treated as the owner of the underlying ordinary
shares that are represented by such ADSs. Accordingly, deposits or withdrawals of ordinary shares for ADSs will not be subject to United States federal income tax.

Taxation of Dividends

Subject to the discussion under
Passive Foreign Investment Company below, the gross amount of distributions on the ordinary shares or ADSs (including amounts withheld to reflect PRC withholding taxes) will be taxable as dividends, to the extent paid out of our
current or accumulated earnings and profits, as determined under United States federal income tax principles. Such income will be includable in your gross income as ordinary income on the day actually or constructively received by you, in the case
of ordinary shares, or by the depositary, in the case of ADSs. Such dividends will not be eligible for the dividends-received deduction allowed to corporations under the Code.

The amount of any dividend paid in Renminbi will equal the United States dollar value of the Renminbi received calculated by reference to the exchange rate in effect on the date the dividend is received
by you,

##### Table of Contents

regardless of whether the Renminbi are converted into United States dollars. If the Renminbi received as a dividend are converted into United States dollars on the date they are received, you
generally will not be required to recognize foreign currency gain or loss in respect of the dividend income. If the Renminbi received as a dividend are not converted into United States dollars on the date of receipt, you will have a basis in the
Renminbi equal to their United States dollar value on the date of receipt. Any gain or loss realized on a subsequent conversion or other disposition of the Renminbi will be treated as United States source ordinary income or loss.

With respect to non-corporate United States Holders, certain dividends received in taxable years beginning before January 1, 2013
from a qualified foreign corporation may be subject to reduced rates of taxation. A foreign corporation is treated as a qualified foreign corporation with respect to dividends received from that corporation on shares (or ADSs backed by such shares)
that are readily tradable on an established securities market in the United States. United States Treasury Department guidance indicates that our ADSs, which are listed on the NYSE, but not our ordinary shares, will be readily tradable on an
established securities market in the United States. There can be no assurance that our ADSs will be considered readily tradable on an established securities market in later years. A qualified foreign corporation also includes a foreign corporation
that is eligible for the benefits of certain income tax treaties with the United States. In the event that we are deemed to be a PRC resident enterprise under PRC tax law (see discussion under TaxationPeoples Republic
of China Taxation), we may be eligible for the benefits of the income tax treaty between the United States and the PRC and, if we are eligible for such benefits, dividends we pay on our ordinary shares, regardless of whether such ordinary
shares are represented by ADSs, would be subject to the reduced rates of taxation.

Non-corporate holders that do not meet a
minimum holding period requirement during which they are not protected from the risk of loss or that elect to treat the dividend income as investment income pursuant to Section 163(d)(4) of the Code will not be eligible for the
reduced rates of taxation regardless of our status as a qualified foreign corporation. In addition, the rate reduction will not apply to dividends if the recipient of a dividend is obligated to make related payments with respect to positions in
substantially similar or related property. This disallowance applies even if the minimum holding period has been met. You should consult your own tax advisors regarding the application of these rules given your particular circumstances.

In the event that we are deemed to be a PRC resident enterprise under PRC tax law, you may be subject to PRC withholding
taxes on dividends paid to you with respect to the ordinary shares or ADSs (see discussion under TaxationPeoples Republic of China Taxation). In that case, however, you may be able to obtain a reduced rate of PRC withholding
taxes under the treaty between the United States and the PRC if certain requirements are met. In addition, subject to certain conditions and limitations, PRC withholding taxes on dividends may be treated as foreign taxes eligible for credit against
your United States federal income tax liability. For purposes of calculating the foreign tax credit, dividends paid on the ordinary shares or ADSs will be treated as foreign-source income and will generally constitute passive category income.
Furthermore, in certain circumstances, if you have held the ordinary shares or ADSs for less than a specified minimum period during which you are not protected from risk of loss, or are obligated to make payments related to the dividends, you will
not be allowed a foreign tax credit for any PRC withholding taxes imposed on dividends paid on the ordinary shares or ADSs. The rules governing the foreign tax credit are complex. You are urged to consult your tax advisors regarding the availability
of the foreign tax credit under your particular circumstances.

Subject to the discussion under Passive Foreign
Investment Company below, to the extent that the amount of any distribution exceeds our current and accumulated earnings and profits for a taxable year, as determined under United States federal income tax principles, the distribution will
first be treated as a tax-free return of capital to the extent of your adjusted basis in the ordinary shares or ADSs, as applicable, and the balance in excess of adjusted basis will be taxed as capital gain recognized on a sale or exchange. However,
we do not expect to keep earnings and profits in accordance with United States federal income tax principles. Therefore, you should expect that a distribution will generally be treated as a dividend (as discussed above).

Passive Foreign Investment Company

Based on the past composition of our income and valuation of our assets, including goodwill, we believe that we were not a PFIC for United
States federal income tax purposes for our taxable year ending December 31, 2010, and we do not expect to become one in the future, although there can be no assurance in this regard.

In general, we will be a PFIC for any taxable year in which:



| |  |  | at least 75% of our gross income is passive income; or
| | - |  | ------------------------------------------------------



| |  |  | at least 50% of the value of our assets (based on an average of the quarterly values) is attributable to assets that produce or are held for the
production of passive income.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For this purpose, passive income generally includes dividends, interest,
royalties and rents (other than royalties and rents derived in the active conduct of a trade or business and not derived from a related person). If we own at least 25% (by value) of the stock of another corporation, we will be treated, for purposes
of the PFIC tests, as owning our proportionate share of the other corporations assets and receiving our proportionate share of the other corporations income.

The determination of whether we are a PFIC is made annually. Accordingly, it is possible that we may become a PFIC in the current or any future taxable year due to changes in our income or asset
composition. Because we have valued our goodwill based on the market value of our ordinary shares and ADSs, a decrease in the price of our ordinary shares or ADSs may result in our becoming a PFIC. If we are a PFIC for any taxable year during which
you hold our ordinary shares or ADSs, you will be subject to special tax rules discussed below.

If we are a PFIC for any
taxable year during which you hold our ordinary shares or ADSs, you will be subject to special tax rules with respect to any excess distribution received and any gain realized from a sale or other disposition, including a pledge, of
ordinary shares or ADSs. Distributions received in a taxable year that are greater than 125% of the average annual distributions received during the shorter of the three preceding taxable years or your holding period for the ordinary shares or ADSs
will be treated as excess distributions. Under these special tax rules:



| |  |  | the excess distribution or gain will be allocated ratably over your holding period for the ordinary shares or ADSs;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we were a PFIC, will be treated as
ordinary income; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



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

In
addition, non-corporate United States Holders will not be eligible for reduced rates of taxation on any dividends received from us in taxable years beginning prior to January 1, 2013, if we are a PFIC in the taxable year in which such dividends
are paid or in the preceding taxable year. You will be required to file Internal Revenue Service Form 8621 if you hold our ordinary shares or ADSs in any year in which we are classified as a PFIC.

If we are a PFIC for any taxable year during which you hold our ordinary shares or ADSs and any of our non-United States subsidiaries is
also a PFIC, a United States Holder would be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC for purposes of the application of these rules. You are urged to consult your tax advisors about the application of
the PFIC rules to any of our subsidiaries.



92

##### Table of Contents

In certain circumstances, in lieu of being subject to the excess distribution rules
discussed above, you may make an election to include gain on the stock of a PFIC as ordinary income under a mark-to-market method, provided that such stock is regularly traded on a qualified exchange. Under current law, the mark-to-market election
may be available to holders of ADSs because the ADSs are listed on the NYSE, which constitutes a qualified exchange, although there can be no assurance that the ADSs will be regularly traded for purposes of the mark-to-market election.
It should be noted that only the ADSs, and not the ordinary shares, are listed on the NYSE. Consequently, if you are a holder of ordinary shares that are not represented by ADSs, you generally will not be eligible to make a mark-to-market election
if we are or were to become a PFIC.

If you make an effective mark-to-market election, instead of applying the PFIC rules
above you would include in each year as ordinary income the excess of the fair market value of your ADSs at the end of the year over your adjusted tax basis in the ADSs. You would be entitled to deduct as an ordinary loss each year the excess of
your adjusted tax basis in the ADSs over their fair market value at the end of the year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. If you make an effective mark-to-market
election, any gain you recognize upon the sale or other disposition of ADSs would be treated as ordinary income and any loss would be treated as ordinary loss, but only to the extent of the net amount previously included in income as a result of the
mark-to-market election. Your adjusted tax basis in the ADSs would be increased by the amount of any income inclusion and decreased by the amount of any deductions under the mark-to-market rules. If you make a mark-to-market election it will be
effective for the taxable year for which the election is made and all subsequent taxable years unless the ADSs are no longer regularly traded on a qualified exchange or the Internal Revenue Service consents to the revocation of the election. You are
urged to consult your tax advisors about the availability of the mark-to-market election, and whether making the election would be advisable in your particular circumstances.

If we are or were to become a PFIC, the rules described above could be avoided if you elected to treat us as a qualified electing fund under Section 1295 of the Code. However, this option
would not be available to you because we do not intend to comply with the requirements necessary to permit you to make this election.

You are urged to consult your tax advisors concerning the United States federal income tax consequences of holding ordinary shares or ADSs if we are considered a PFIC in any taxable year.

Taxation of Capital Gains

For United States federal income tax purposes and subject to the discussion under Passive Foreign Investment Company above, you will recognize taxable gain or loss on any sale, exchange
or other taxable disposition of ordinary shares or ADSs in an amount equal to the difference between the amount realized for the ordinary shares or ADSs and your tax basis in the ordinary shares or ADSs. Such gain or loss will generally be capital
gain or loss. Capital gains of non-corporate United States Holders derived with respect to capital assets held for more than one year are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Any gain
or loss recognized by you will generally be treated as United States-source gain or loss. However, in the event that we are deemed to be a PRC resident enterprise under PRC tax law, we may be eligible for the benefits of the income tax
treaty between the United States and the PRC. Under that treaty, if any PRC tax was to be imposed on any gain from the disposition of the ordinary shares or ADSs, a United States Holder that is eligible for treaty benefits may elect to treat the
gain as PRC-source income. You are urged to consult your tax advisors regarding the tax consequences if a foreign tax is imposed on gain on a disposition of our ordinary shares or ADSs, including the availability of the foreign tax credit under your
particular circumstances.

Information Reporting and Backup Withholding

In general, information reporting will apply to dividends in respect of our ordinary shares or ADSs and to the proceeds from the sale,
exchange or redemption of our ordinary shares or ADSs that are paid to you within

the United States (and in certain cases, outside the United States), unless you are an exempt recipient such as a corporation. A backup withholding tax may apply to such payments if you fail to
provide a correct taxpayer identification number or certification of other exempt status or fail to report in full dividend and interest income or otherwise fail to comply with the backup withholding rules. Backup withholding is not an additional
tax. Rather, any amounts withheld as backup withholding may be credited against your United States federal income tax liability, if any, and you may obtain a refund of any excess withheld under the backup withholding rules by filing the appropriate
claim for refund with, and provided the required information is properly furnished to, the Internal Revenue Service.

PROSPECTIVE PURCHASERS OF OUR ADSS OR ORDINARY SHARES SHOULD CONSULT WITH THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S.
FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY ADDITIONAL TAX CONSEQUENCES RESULTING FROM PURCHASING, HOLDING OR DISPOSING OF OUR ADSS OR ORDINARY SHARES, INCLUDING THE APPLICABILITY AND EFFECT OF THE TAX LAWS OF ANY STATE,

|ITEM 11. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

Market risk is the risk of loss related to adverse changes in market prices, including interest rates and foreign exchange rates, of financial instruments. In the normal course of business, we are
routinely subject to a variety of risks, including changes in foreign currency exchange rates and interest rates and inflation.

Foreign Exchange Risk

A majority of our sales are denominated in U.S. dollars, with the remainder denominated in Renminbi, Euro and Japanese Yen. Our costs and capital expenditures are largely denominated in Renminbi. The
value of the Renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in the PRCs political and economic conditions. The conversion of Renminbi into foreign currencies, including the
U.S. dollar, is based on rates set by the Peoples Bank of China. The conversion of Renminbi into foreign currencies, including U.S. dollars, is based on rates set by the Peoples Bank of China. The PRC government allowed the Renminbi to
appreciate by more than 20% against the U.S. dollar between July 2005 and July 2008. Between July 2008 and June 2010, this appreciation halted and the exchange rate between the Renminbi and the U.S. dollar remained within a narrow band. Since June
2010, the PRC government has allowed the Renminbi to appreciate slowly against the U.S. dollar again. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the Renminbi and the U.S. dollar
in the future. Fluctuations in currency exchange rates could have a significant effect on our financial condition and results of operations due to the extent of our transactions denominated in foreign currencies as well as any mismatch among various
foreign currency-denominated assets and liabilities. Fluctuations in exchange rates pertaining to our foreign currency transactions, particularly between the U.S. dollar and Renminbi, affect our gross and net profit margins.

The functional currency of our PRC subsidiaries is the Renminbi. Transactions denominated in other currencies are re-measured into
Renminbi and any resulting foreign currency exchange gains and losses are recognized in our consolidated statements of income. Our exposure to foreign currency exchange risk primarily relates to our accounts receivable and cash that are denominated
in currencies other than the Renminbi. As of December 31, 2010, we held an equivalent of RMB137.9 million (US$20.9 million) in accounts receivable, of which RMB68.2 million (US$10.3 million) was denominated in U.S. dollars. As of
December 31, 2008, December 31, 2009 and December 31, 2010, we also held an equivalent of RMB180.6 million, RMB351.1 million and RMB98.7 million (US$15.0 million), respectively, in cash, of which RMB19.3 million, RMB223.4
million and RMB38.5 million (US$5.8 million), respectively, was denominated in U.S. dollars. Generally, the appreciation of the Renminbi against the U.S. dollar will result in foreign exchange losses for monetary assets denominated in U.S. dollars
and foreign currency exchange gains for monetary liabilities denominated in U.S. dollars, and vice versa. We incurred net foreign currency exchange losses of approximately RMB9.5 million, RMB2.0 million and RMB 3.2 million (US$0.5 million)
during 2008, 2009 and 2010, respectively, which are reported in our consolidated statements of income. These net foreign currency exchange losses recognized under our statement of income were partially offset by net foreign currency translation
adjustments of RMB2.4 million, RMB54,000 and RMB1.6 million (US$0.2 million) in 2008, 2009 and 2010, respectively.

We and our
subsidiaries located outside the PRC use the U.S. dollar as our functional currency. Our assets and liabilities and those of our subsidiaries located outside the PRC are translated into our reporting currency, the Renminbi, using the exchange rate
on the balance sheet date. Our revenues and expenses and those of our subsidiaries located outside the PRC are translated into our reporting currency at average rates prevailing during the year. Our gains and losses resulting from the translation of
the financial statements and those of our subsidiaries located outside the PRC are reported as a separate component of accumulated other comprehensive income within equity in our consolidated financial statements. As of December 31, 2008, our
net liabilities denominated in currencies other than RMB of our subsidiaries located outside of the PRC was RMB23.3 million. As of December 31, 2009 and December 31, 2010, our net assets denominated in currencies other than RMB of our
subsidiaries located outside of the PRC was RMB109.0 million and RMB25.3 million (US$3.8 million). We



95



---

##### Table of Contents

recognized foreign currency translation gains of approximately RMB2.4 million, RMB54,000 and RMB1.6 million (US$0.2 million) in 2008, 2009 and 2010, respectively. We have reported a net foreign
currency translation gain despite the Renminbi appreciation against the U.S. dollar because the majority of our total assets and those of our subsidiaries located outside of the PRC comprise of investments in the PRC subsidiaries, which is
eliminated on consolidation. The remaining assets and liabilities are mostly denominated in Renminbi, except for amounts due to a related party transaction totaling RMB38 million as of December 31, 2008 and nil as of December 31, 2009,
which are denominated in U.S. dollars.

We are exposed to the exchange risk of the Renminbi against the U.S. dollar as
majority of our sales are denominated in the U.S. dollar while majority of our purchases are denominated in the Renminbi. We currently do not plan to enter into any hedging arrangements to reduce the effect of our foreign currency exchange risk
exposure. Even if we decide to enter into any such hedging activities in the future, we cannot assure you that we would be able to effectively manage our foreign currency exchange risk exposure.

Interest Rate Risk

Our exposure to interest rate risk relates to interest expense incurred by our borrowings and interest income on our interest-bearing cash and pledged deposit balances. As of December 31, 2010, we
had RMB 25 million (US$3.8 million) of short-term bank borrowings and long-term bank borrowings, current portion, and RMB155.5 million (US$23.6 million) of interest-bearing cash and pledged deposit balances, respectively.

We have not used any derivative financial instruments or engaged in any interest rate hedging activities to manage our interest rate risk
exposure. Our future interest expense on our long-term borrowings may increase or decrease due to changes in market interest rates. Our bank borrowings had a weighted average interest rate of 5.27% per annum during 2010 and mature in 2011. Our
future interest income on our interest-bearing cash balances may increase or decrease due to changes in market interest conditions.

Our interest expense and interest income has historically been immaterial to our consolidated financial statements. Consequently, we believe we currently do not have any significant interest rate risk
exposure.

Inflation

Inflation in China has not materially impacted our results of operations in recent years. According to the National Bureau of Statistics in China, consumer price inflation in China was 5.9%, -0.7% and
3.3% in 2008, 2009 and 2010, respectively. Although we have not been materially affected by inflation in the past, we cannot assure you that we will not be affected by higher rates of inflation in China in the future which could affect our costs and
our advantages as a China-based manufacturer.

|Cancellation of ADSs                                                                               |  | Up to US$0.05 per ADS cancelled
|Distribution of cash dividends or other cash distributions                                         |  | Up to US$0.02 per ADS held     
|Distribution of ADSs pursuant to stock dividends, free stock distributions or exercises of rights. |  | Up to US$0.05 per ADS held     
|Distribution of securities other than ADSs or rights to purchase additional ADSs                   |  | Up to US$0.05 per ADS held     

Depositary Charges

In
addition, an ADS holder shall be responsible for the following charges:



| |  |  | taxes (including applicable interest and penalties) and other governmental charges;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | such registration fees as may from time to time be in effect for the registration of common shares or other deposited securities on the share register
and applicable to transfers of common shares or other deposited securities to or from the name of the custodian, the depositary or any nominees upon the making of deposits and withdrawals, respectively;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | such cable, telex and facsimile transmission and delivery expenses as are expressly provided in the deposit agreement to be at the expense of ADS
holders and beneficial owners of ADSs;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the expenses and charges incurred by the depositary in the conversion of foreign currency; and
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | the fees and expenses incurred by the depositary, the custodian or any nominee in connection with the servicing or delivery of deposited securities.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------

Depositary fees payable upon the issuance and cancellation of ADSs are typically paid to the depositary by
the brokers (on behalf of their clients) receiving the newly-issued ADSs from the depositary and by the brokers (on behalf of their clients) delivering the ADSs to the depositary for cancellation. The brokers in turn charge these transaction fees to
their clients.

Depositary fees payable in connection with distributions of cash or securities to ADS holders and the
depositary services fee are charged by the depositary to the holders of record of ADSs as of the applicable ADS record date. The depositary fees payable for cash distributions are generally deducted from the cash being distributed. In the case of
distributions other than cash (i.e., stock dividends, rights offerings), the depositary charges the applicable fee to the ADS record date holders concurrent with the distribution. In the case of ADSs registered in the name of the investor (whether
certificated or un-certificated in direct registration), the depositary sends invoices to the applicable record date ADS holders. In the case of ADSs held in brokerage and custodian accounts via the central clearing and settlement system, The
Depository Trust Company, or DTC, the depositary generally collects its fees through the systems provided by DTC (whose nominee is the registered holder of the ADSs held in DTC) from the brokers and custodians holding ADSs in their DTC accounts. The
brokers and custodians who hold their clients ADSs in DTC accounts in turn charge their clients accounts the amount of the fees paid to the depositary.

##### Table of Contents

In the event of refusal to pay the depositary fees, the depositary may, under the terms of
the deposit agreement, refuse the requested service until payment is received or may set off the amount of the depositary fees from any distribution to be made to the ADS holder.

The fees and charges ADS holders may be required to pay may vary over time and may be changed by us and by the depositary. ADS holders
will receive prior notice of such changes.

Payments by Depositary

In 2010, we received reimbursement funds of US$148,000 from Citibank, N.A., the Depositary Bank, for our ADR program.

Disclosure
Controls and Procedures

As of the end of the period covered by this annual report, an evaluation has been carried out
under the supervision and with the participation of our management, including our chief executive officer and our principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as such term
is defined under Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended. Based on that evaluation, our chief executive officer and principal financial officer have concluded that our disclosure controls
and procedures are effective.

Managements Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule
13a-15(f) under the Securities Exchange Act of 1934, as amended. Our management evaluated the effectiveness of our internal control over financial reporting based on criteria established in the framework in Internal Control-Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, our management has concluded that our internal control over financial reporting was effective as of December 31, 2010.

Internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records
that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with U.S. generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and/or Board; and (iii) provide reasonable assurance regarding prevention or
timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

##### Table of Contents

Our internal control over financial reporting is designed to provide reasonable, but not
absolute, assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness of our internal control over financial reporting to future periods are subject to the risk that controls may become inadequate because of

Attestation Report of the Registered Public Accounting Firm

Report of Independent Registered Public Accounting Firm

The Board of Directors and
Shareholders of

Chemspec InternationalLimited:

We have audited Chemspec International Limiteds internal control over financial reporting as of December 31, 2010, based on criteria established in Internal ControlIntegrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Chemspec International Limiteds management is responsible for maintaining effective internal control over financial reporting and for its
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Managements Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the
Companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the
standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in
all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal
control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors
of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Controls

Except as discussed below, there were no changes in internal control for the year ended December 31, 2010 that have materially affected, or are reasonably likely to materially affect, our internal

Public Company Accounting Oversight Board. For details of such a significant deficiency, see Item 5 of our annual report on Form 20-F for 2009 filed with the Securities and Exchange Commission on June 17, 2010. To address this
significant deficiency, as well as certain other control deficiencies, we took the following measures to rectify the deficiency in 2010:

| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | hired an external inspection firm to ensure that construction progress milestones are properly and timely reported then recorded in our accounting
books, and properly and timely transferred to fixed assets once projects are completed.

We
are a foreign private issuer (as such term is defined in Rule 3b-4 under the Exchange Act), and our ADSs, each representing 60 ordinary shares, are listed on the New York Stock Exchange, or NYSE. Under Section 303A of the NYSE
Listed Company Manual, NYSE-listed companies that are foreign private issuers are permitted to follow home country practice in lieu of the corporate governance provisions specified by the NYSE with limited exceptions. The following summarizes some
significant ways in which our corporate governance practices differ from those followed by domestic companies under the listing standards of the NYSE:



| |  |  | The NYSE standards for domestic companies require that non-management directors meet at regularly scheduled executive sessions without management.
Except for meetings in August and November 2010 and independent committee meetings in connection with the going private transaction, our non-management directors have not met in executive sessions without management, and there is no requirement
under the laws of the Cayman Islands that our non-management directors meet in executive sessions.

Report of Independent Registered Public Accounting Firm

THE BOARD OF DIRECTORS AND SHAREHOLDERS OF

CHEMSPEC INTERNATIONAL LIMITED:

We have audited the accompanying consolidated
balance sheets of Chemspec International Limited and subsidiaries as of December 31, 2009 and 2010, and the related consolidated statements of income, equity and comprehensive income, and cash flows for each of the years in the three-year
period ended December 31, 2010. These consolidated financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Chemspec International Limited and subsidiaries as of December 31, 2009 and 2010, and the results of their operations and their cash flows for each of the years in the three-year
period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles.

The accompanying
consolidated financial statements as of December 31, 2010 and for the year then ended have been translated into United States dollars solely for the convenience of the reader. We have audited the translation and, in our opinion, such financial
statements expressed in Renminbi have been translated into United States dollars on the basis set forth in Note 2(c) to the consolidated financial statements.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Chemspec International Limiteds internal control over financial reporting as
of December 31, 2010, based on criteria established in Internal Control-Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated June 20, 2011 expressed an
unqualified opinion on the effectiveness of the Chemspec International Limiteds internal control over financial reporting.

Notes:

|(i) | In 2008, the Group acquired an additional 20% equity interest in Huajing Company from the noncontrolling interest holder for cash consideration of RMB8,000. See Note
20(b).
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(ii) | In February 2008, the Group completed its acquisition of an 80% equity interest in Jiangsu Wei Er from independent third parties. In November 2009, the Group acquired
the remaining 20% equity interest in Jiangsu Wei Er from the noncontrolling interest holders for cash consideration of RMB 41,000. See Notes 20(a) and 20(b).
|---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(iii) | Binhai Kangjie was established in 2009. The Group contributed RMB18,400 for a 92% equity interest in Binhai Kangjie and the noncontrolling interest holder contributed
RMB1,600 for an 8% equity interest. In March 2010, the Group acquired an additional 8% equity interest in Binhai Kangjie from the noncontrolling interest holder for cash consideration of RMB2,800. See Note 20(b).
|----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(iv) | The Group acquired 100% equity interest in Kangpeng Nong Hua in November 2009 for cash consideration of RMB25,000. As Dr. Jianhua Yang (Dr. Yang) held
more than 50% voting ownership interest of both the Company and Kangpeng Nong Hua at the date of the acquisition, it is considered a transaction between entities under common control. The Companys consolidated financial statements have been
retrospectively adjusted to reflect the acquisition since October 8, 2008, which is the earliest date that both entities were under the common control of Dr. Yang. See Note 20(c).
|---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Basis of presentation

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). This basis of accounting differs in certain material
respects from that used for the preparation of the books of account of the Companys subsidiaries, which are prepared in accordance with the accounting principles and the relevant financial regulations established by the Ministry of Finance of
the PRC (PRC GAAP), the accounting standards used in the PRC. The accompanying consolidated financial statements reflect necessary adjustments not recorded in the books of account of the Companys subsidiaries to present them in
conformity with U.S. GAAP.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a) Principles of consolidation

The accompanying consolidated financial statements include the financial statements of the Company and its subsidiaries. Investments in companies of which the Group has significant influence, but not a
controlling interest are accounted for using the equity method of accounting as discussed in footnote 2(n). All significant intercompany transactions and balances have been eliminated in consolidation.

(b) Use of estimates

The preparation of financial statements in accordance with U.S. GAAP requires management of the Group to make estimates and assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items
subject to such estimates and assumptions include collectibility of trade receivables, realization of inventories and deferred income tax assets, the determination of useful lives and residual values of property, plant and equipment, and the
determination of fair values of share-based compensation awards and assets and liabilities acquired in purchase business combinations and the measurement of income tax uncertainties. These estimates are often based on judgments and assumptions that
management believes to be reasonable but are inherently uncertain and unpredictable.

(c) Foreign currency transactions and translation

The Groups reporting currency is the RMB. The functional currency of the Companys subsidiaries located in the PRC is the RMB
as the PRC is the primary economic environment in which these entities operate. Transactions at these subsidiaries that are denominated in currencies other than the RMB are translated into RMB at the exchange rates prevailing at the dates of the
transaction. Monetary assets and liabilities denominated in foreign currencies are translated into RMB using the applicable exchange rates at each balance sheet date. The resulting exchange differences are recorded in foreign currency exchange gain
(loss), net in the consolidated statements of income.

The functional currency of the Company and its subsidiaries located
outside of the PRC is the U.S. dollar. Assets and liabilities of the Company and subsidiaries located outside of the PRC are translated into RMB using the exchange rates at each balance sheet date. Revenue and expenses are translated into RMB at
average rates prevailing during the reporting period. The gains and losses, net of tax, resulting from translation into RMB are reported as a separate component of accumulated other comprehensive income within equity.

For the convenience of the readers, the December 31, 2010 RMB amounts included in the accompanying consolidated financial statements
have been translated into U.S. dollars at the rate of US$1.00=RMB6.6000, being the noon buying rate for U.S. dollars in the City of New York in effect on December 30, 2010 for cable transfers in RMB per U.S. dollar as certified for customs
purposes by the Federal Reserve Bank of New York. No representation is made that the RMB amounts could have been, or could be, converted into U.S. dollars at that rate or at any other rate on December 30, 2010 or at any other date.

(d) Commitments and contingencies

In the normal course of business, the Group is subject to loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources. An accrual for a loss contingency is
recorded when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred.

(e) Cash

Cash consists of cash on hand and cash at banks. As of December 31, 2010, the Group held cash RMB69,605 (US$10,546) in major financial institutions located in the PRC (2009: RMB239,073) and RMB
29,114 (US$4,411) in major financial institutions in Hong Kong (2009: RMB86,028). Management believes that these major financial institutions have acceptable credit rating.

(f) Pledged bank deposits

Pledged bank deposits represent amounts
held by financial institutions in the PRC, which are not available for the Groups use, as security for issuance of bills payable and letters of credit. Upon maturity of the bills payable, which is generally within 6 months, the cash becomes
available for use by the Group. Pledged bank deposits related to purchase of inventories are reported within cash flows from operating activities and pledged bank deposits related to purchase of property, plant and equipment are reported within cash
flows from investing activities in the consolidated statements of cash flows.

(Amounts expressed in thousands, except share and per share data)



(g) Accounts receivable

Accounts receivable primarily represent amounts due from customers, that are recorded at the invoiced amount and do not bear interest.
Management reviews its accounts receivable on a periodic basis and records allowances when there is a doubt as to the collectibility of the balance. In evaluating the collectibility of an account receivable balance, management considers various
factors, including, the age of the balance, customer specific facts and economic conditions. Accounts receivable balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is
considered remote. The Group does not have any off-balance-sheet credit exposure related to its customers.

(h)
Inventories

Inventories are stated at the lower of cost or market. Cost is determined using the weighted average
method. Cost of work-in-progress and finished goods is comprised of direct materials, direct labor and related manufacturing overhead based on normal operating capacity.

(i) Property, plant and equipment, net

Property, plant and
equipment are stated at cost. Depreciation is calculated on a straight-line method over the estimated useful lives of the assets, taking into consideration the assets estimated salvage value. Leasehold improvements are amortized over the
shorter of the lease term or estimated useful lives. When items are retired or otherwise disposed of, loss is charged for the difference between the net book value and proceeds received thereon. Ordinary maintenance and repairs are charged to
expense as incurred. The estimated useful lives of the Groups property, plant and equipment are as follows:



|                       |  |  |            | 
|---------------------- |  |  | ---------- | 
|Buildings              |  |  | 20 years   | 
|Plant machinery        |  |  | 5-10 years | 
|Office equipment       |  |  | 3-5 years  | 
|Motor vehicles         |  |  | 4-5 years  | 
|Leasehold improvements |  |  | 5 years    | 

Costs incurred during
the construction and installation of the assets are initially capitalized as construction in progress and transferred to property, plant and equipment when the assets are ready for their intended use, at which time depreciation commences. The
capitalized costs include an allocation of interest cost incurred.

(j) Land use rights

Land use rights represent the cost of land use rights in the PRC. Land use rights are recorded at cost and charged to expense on a
straight-line basis over the term of the land use rights.

(k) Intangible assets

Intangible assets represent customer relationship, which are amortized on a straight-line basis over their estimated useful lives of 9
years.

Amortization expense for intangible assets was RMB27, RMB108 and RMB109 (US$17) for the years ended December 31,
2008, 2009 and 2010. Estimated amortization expense for each of the next five years is RMB108.

(l) Goodwill

Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in a purchase businesses
combination. Goodwill is not amortized, but is instead evaluated for impairment at least annually. The goodwill impairment test is a two-step process. Under the first step, the estimated fair value of the reporting unit, which in this case is the
Group as a whole, is compared with its carrying value (including goodwill). The Group used its market capitalization based on the quoted market price of its ordinary shares in determining the fair value of the reporting unit. If the estimated fair
value of the reporting unit is less than its carrying value, an indication of goodwill impairment exists and management must then perform step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess
of the carrying amount of the reporting units goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price
allocation and the residual fair value after this allocation is the implied fair value of the reporting unit goodwill.

The
Company performs its annual impairment review of goodwill at December 31, or when a triggering event occurs between annual impairment tests. No impairment of goodwill was recognized for the years ended December 31, 2008, 2009 and 2010.

(m) Impairment of long-lived assets

Long-lived assets including property, plant and equipment, land use rights, and intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate
that their carrying amounts may not be recoverable. Long lived assets are grouped for impairment testing at the lowest level for which there are identifiable cash flows that are largely independent of other asset groups. The approach in evaluating
whether an asset group has identifiable cash flows that are largely independent of the cash flows of other asset groups focuses on the degree to which the Companys total cash flows (inflows and outflows) depend on the activities of one or more
other asset groups of the Company. Recoverability of the asset groups is measured by a comparison of the carrying amount of the asset groups to the estimated undiscounted future cash flows expected to be generated. If the carrying amount of the
asset groups exceed the sum of its estimated undiscounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset groups exceed their fair value. Fair value is determined through various
valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. No impairment of long-lived assets was recognized for the years ended December 31, 2008, 2009 and
2010.

(n) Equity investment in an affiliate

Equity investments where the Company does not have a controlling financial interest, but has the ability to exercise significant influence
over the operating and financial policies of the investee, are accounted for using the equity method. Under the equity method of accounting, the Groups share of the investees results of operations is reported as equity in income (loss)
of an affiliate in the consolidated statements of income.

The Group recognizes an impairment loss when there is a decline in
value below the carrying value of the equity investment that is considered to be other-than-temporary. The process of assessing and determining whether impairment on an investment is other-than-temporary requires a significant amount of judgment. To
determine whether impairment is other-than-temporary, management considers whether it has the ability and intent to hold the investment until recovery and whether evidence indicating the carrying value of the investment is recoverable outweighs
evidence to the contrary. Evidence considered in this assessment includes the reasons for the impairment, the severity and duration of the decline in value, any change in value subsequent to the period end, and forecasted performance of the
investee. Based on managements evaluation, there were no impairment charges on the equity investment for the years ended December 31, 2009 and 2010.

(Amounts expressed in thousands, except share and per share data)



(o) Bills payable

Bills payable represent bills issued by financial institutions to the Groups suppliers that normally do not exceed six months. The
bills payable are recognized when the banks accept the bills and the Group is liable to pay the banks. The bills payable are derecognized when the Group pays the banks and is relieved of its obligation for the liability.

(p) Revenue recognition

The Group sells specialty chemicals directly to end users that incorporate them into their products, and to trading or distribution companies that then sell the specialty chemicals to end users. Sales
represent the invoiced value of products sold, net of value added taxes (VAT). The Group recognizes revenue from the sales of chemical compounds when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is
fixed and determinable, and collectibility is reasonably assured. For sales to end users outside the PRC, products are considered delivered when the goods have been loaded on the ship at the port of shipment. For sales to end users in the PRC,
delivery occurs upon receipt of products by the customers. For sales to trading companies, delivery occurs upon receipt of products by the customers at the customers warehouse or designated destination.

In the PRC, VAT of 17% on invoice amount is collected, in respect of the sales of goods to customers in the PRC, on behalf of tax
authorities. VAT collected from customers in the PRC, net of VAT paid, is recorded as a liability in the consolidated balance sheets until it is paid to the authorities. No VAT is collected in respect of the sales of goods to customers outside the
PRC. For VAT paid, a certain percent is recorded as a receivable (see Note 5) in the consolidated balance sheets until it is recovered from the tax authorities. The non-refundable portion of VAT paid is recognized as a part of cost of sales when the
corresponding sales are recognized.

(q) Government grants

Government grants are recognized in the consolidated balance sheets initially as deferred income when received and recognized as income
when all the conditions for receipt have been met. Grants that reimburse the Group for expenses incurred are recognized as income on a systematic basis in the same periods in which the expenses are incurred. Grants that reimburse the Group for the
cost of an asset are recognized as income on a straight-line basis over the useful life of the assets.

During the years ended
December 31, 2008, 2009 and 2010, government grants of RMB5,616, RMB10,541 and RMB7,511 (US$1,138) were received from local government authorities for the Group to reimburse its research and development expenditures, and RMB50, RMB971 and
RMB5,152 (US$781) have been recognized as income, respectively.

(r) Shipping and handling costs

Costs to ship products to customers are included in selling expenses in the consolidated statements of income. Cost to ship products to
customers were RMB8,662, RMB6,026 and RMB8,138 (US$1,233) for the years ended December 31, 2008, 2009 and 2010, respectively.

(s) Advertising costs

Advertising costs are charged to expense in
the period incurred and are included in selling expenses in the consolidated statements of income. The Group incurred advertising expenses totaling RMB64, RMB537 and RMB349 (US$53) for the years ended December 31, 2008, 2009 and 2010,
respectively.

(t) Research and development costs

Research and development costs are expensed as incurred.

(u) Income taxes

Income taxes are accounted for under the asset and
liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax
bases and tax loss carryforwards. Deferred income tax assets are reduced by a valuation allowance to the extent management concludes it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Deferred
income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and
liabilities of a change in tax rates or laws is recognized in the statements of income in the period that the change in tax rates or tax laws is enacted.

The Group recognizes in the consolidated financial statements the impact of a tax position, if that position is more likely than not of being sustained upon examination, based on the technical merits of
the position. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Group
has elected to classify interest and penalties related to unrecognized tax benefits, if and when required, as part of income tax expense in the consolidated statements of income.

(v) Share-based compensation

The Group measures the costs of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award and recognizes the costs over the period the
employee is required to provide service in exchange for the award, which generally is the vesting period. The estimate of the fair value of the equity award granted before the initial public offering (IPO) of the Companys ordinary shares is
determined based on consideration of both comparable valuation and discounted cash flow methods, taking into account the terms and conditions upon which the equity instrument was granted.

(w) Employee benefit plans

Pursuant to PRC regulations, the Companys PRC subsidiaries are required to participate in various defined contribution plans organized by municipal and provincial governments for their employees.
These entities are required to make contributions for each employee to these plans at rates ranging from 30% to 44% on a standard salary base determined by the local Social Security Bureau. Under these plans, certain pension, medical and other
welfare benefits are provided to the employees. The Groups PRC subsidiaries have no other obligation for the payment of employee benefits associated with these plans beyond the contributions described above. Employee benefits associated with
these plans are expensed monthly as the related service is provided. The total amount of such contributions for the years ended December 31, 2008, 2009 and 2010 were RMB7,220, RMB11,656 and RMB13,114 (US$1,987), respectively.

(x) Earnings per share

Basic earnings per share is computed by dividing net income attributable to Chemspec International Limited shareholders by the weighted average number of ordinary shares outstanding during the year.

Diluted earnings per share is calculated by dividing net income attributable to Chemspec
International Limited shareholders as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary shares and dilutive ordinary share equivalents outstanding during the year. Ordinary share
equivalents consist of the ordinary shares issuable upon the exercise of outstanding share options (using the treasury stock method). Potential dilutive securities are not included in the calculation of diluted earnings per share if the effect is
anti-dilutive.

(y) Segment reporting

The Groups chief operating decision maker has been identified as its Chief Executive Officer. The Group has one operating segment, namely manufacturing of specialty chemicals. Geographic revenue
information is presented in Note 18.

(z) Capitalized interest

The Groups policy is to capitalize interest cost incurred on debt during the construction of major projects exceeding one year. A
reconciliation of total interest cost to Interest expense as reported in the consolidated statements of income for years ended December 31, 2008, 2009 and 2010, is as follows:

(aa) Fair value measurements

The Group applies the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification
(ASC) Subtopic 820-10, Fair Value Measurements, or ASC Subtopic 820-10, for fair value measurements of financial assets and financial liabilities and for fair value measurements of nonfinancial items that are recognized or
disclosed at fair value in the financial statements. ASC Subtopic 820-10 also establishes a framework for measuring fair value and expands disclosures about fair value measurements.

FASB ASC Subtopic 820-10 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an
orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most
advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

FASB ASC Subtopic 820-10 establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair
value. FASB ASC Subtopic 820-10 establishes three levels of inputs that may be used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1
measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:



| |  |  | Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the
measurement date
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



F-14

##### Table of Contents

CHEMSPEC INTERNATIONAL LIMITED AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(CONTINUED)

(Amounts expressed in thousands, except share and per share data)



| |  |  | Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or
indirectly
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3 inputs are unobservable inputs for the asset or liability
| | - |  | -----------------------------------------------------------------

The level in the fair value hierarchy within which a fair measurement in its entirety falls is based on the lowest level input that is
significant to the fair value measurement in its entirety.

The level in the fair value hierarchy within which a fair value
measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety.

The Group did not have any assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2009 and 2010.

British Virgin Islands

Under the current laws of the British Virgin Islands, the Group is not subject to income tax. In addition, upon any payment of dividends
by the Group, no British Virgin Islands withholding tax is imposed.

Hong Kong

No current income tax provisions were made for Hong Kong Profits Tax as the Group did not have assessable profits subject to Hong Kong
Profits Tax during the years ended December 31, 2008, 2009 and 2010.

PRC

Shanghai ChemSpec, Taixing ChemSpec and Shanghai Wan Su were converted from domestic enterprises to foreign invested enterprises
(FIEs) beginning in August 2006, October 2006 and September 2006, respectively. Prior to January 1, 2008, a production-oriented FIE could be entitled to a 2-year full exemption followed by a 3-year 50% exemption tax holiday
(tax holiday). Taixing ChemSpec and Shanghai Wan Su qualified as production-oriented FIEs and were entitled to the tax holiday benefit beginning in 2007. As of December 31, 2007, there was an uncertainty regarding Shanghai
ChemSpecs qualification as a production-oriented FIE. In addition, Shanghai Qi Yue, being registered in the Pudong New Area, Shanghai, was subject to a reduced income tax rate of 15%.

On March 16, 2007, the PRC government enacted the new Enterprise Income Tax law (new EIT law), which changed the
statutory income tax rate to 25%. The new EIT law was effective as of January 1, 2008. The new EIT law and its relevant regulations provide a 5-year transition period from its effective date for those companies which were entitled to a
preferential lower tax rate under the then effective tax laws and regulations, as well as grandfathering tax holidays.

The
Companys PRC subsidiaries are subject to income tax at 25% from 2008 onwards, except for the followings:



| | (i) | Shanghai ChemSpec was converted into a FIE in August 2006 and was subject to income tax at 27%. Its tax returns were filed using this tax rate without any tax holiday
benefit beginning in August 2006. Upon the receipt of the notification issued by the local tax bureau of Shanghai Putuo district in July 2008, Shanghai ChemSpec was entitled to a tax holiday retroactively from August 1, 2006 to
December 31, 2010. As a result, Shanghai ChemSpec is subject to income tax at 12.5% from 2008 to 2010 and at 25% from 2011 onwards;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Taixing ChemSpec and Shanghai Wan Su were exempt from income tax for 2007 and 2008, and are subject to income tax at 12.5% from 2009 to 2011 and at 25% from 2012
onwards;
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | Shanghai Qi Yue is subject to income tax at 18%, 20%, 22%, 24% and 25% for 2008, 2009, 2010, 2011 and 2012 onwards, respectively;
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------



| | (iv) | Jiangsu Wei Er was subject to income tax at 25% for 2008. It qualified as an Advanced and New Technology Enterprise under the new EIT law in 2009 and is
entitled to the preferential income tax rate of 15% from 2009 to 2011. Thereafter, it is subject to income tax at 25%.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The new EIT law and its relevant regulations also impose a withholding tax at 10%, unless reduced by a tax treaty, for dividend distributions from earnings accumulated beginning on January 1, 2008.

earnings generated prior to January 1, 2008 are exempt from such withholding tax. Under the China-HK tax arrangement, a qualified Hong Kong tax resident which is the beneficial
owner and holds 25% or more of the equity interest in a PRC-resident enterprise is entitled to a reduced withholding rate of 5%.

The Companys subsidiaries in the PRC are directly or indirectly held by one of the Groups intermediate holding companies, Wisecon, a Hong Kong tax resident. On March 28, 2011, Shanghai
Chemspec received approval from its tax authority in-charge confirming that the reduced withholding tax rate of 5% would be applied on its dividends to Wisecon effective from 2008 to 2010. Based upon the approval received and an assessment of the
tax residency status of Wisecon and its ability to control its funds, management believes it is more likely than not that any dividends paid by the PRC subsidiaries from earnings generated beginning on January 1, 2008 will be subject to PRC
withholding tax at 5%.

The income tax expense (benefit) attributable to income from operations, which is all derived from PRC
sources, consists of:

|(i) | Amount of RMB16,274 for the year ended December 31, 2008 represents income tax refund received by Wisecon for making additional capital contribution to Shanghai
ChemSpec in 2007. The tax refund is reported as a reduction of income tax expense in the consolidated statements of income and is recognized in the period when Wisecon received the approval from the state tax bureau of Shanghai Putuo District since
government approval is required under the relevant PRC tax laws before an entity is entitled to the tax benefit.

|(ii) | Amount of RMB42,493 for the year ended December 31, 2008 represents income tax refund received by Shanghai ChemSpec for the income tax paid for the period from
August 1, 2006 to December 31, 2007. In 2007, Shanghai ChemSpec filed the application for the tax holiday, which was rejected by the tax bureau. Therefore, management believed that it was more likely than not that it would not be entitled
to the tax holiday benefit, and Shanghai ChemSpec did not claim such benefit in its tax returns as well as in its financial statements until the formal approval from the tax bureau is obtained. In July 2008, the local tax bureau of Shanghai Putuo
district notified Shanghai ChemSpec that it is entitled to an exemption from income tax retroactively for the period from August 1, 2006 to December 31, 2007 and a 50% reduction in the income tax in the subsequent three years. The tax
refund was recorded as a reduction of income tax expense in the consolidated statements of income.

|(iii) | Without the tax holiday, the Groups basic and diluted earnings per share for the years ended December 31, 2008, 2009 and 2010 would have been reduced by
RMB0.06, RMB0.01 and RMB0.02 (US$0.00), respectively.

The increase in the
valuation allowance during the years ended December 31, 2008, 2009 and 2010 were RMB273, RMB1,194 and RMB970, respectively. The increase for each of 2009 and 2010 was mainly due to the allowance provided against deferred income tax assets of
Kangpeng Nong Hua. As of December 31, 2010 and for the two years then ended, Kangpeng Nong Hua was in cumulative loss position.

As of December 31, 2010, no valuation allowance was provided against the deferred income tax assets of RMB4,772 recognized for Shanghai Qi Yue, Jiangsu Wei Er and Binhai Kangjie. Management considers
the projected future taxable income in making this assessment. In order to fully utilize the deferred income tax assets, Shanghai Qi Yue, Jiangsu Wei Er and Binhai Kangjie will need to generate total future taxable income of approximately RMB4,754
and RMB23,755 prior to the expiration of the tax loss carryforwards in 2014 and 2015, respectively.

Based upon an assessment
of the tax benefit of existing deductible temporary differences, the level of historical taxable income projections for future taxable income over the periods in which the deferred income tax assets are deductible or can be utilized and tax planning
strategies, management believes it is more likely than not that the Group will realize the benefits of its deferred income tax assets, net of valuation allowances, as of December 31, 2009 and 2010. The amount of the deferred income tax assets
considered realizable, however, could be reduced in the near term if estimates of future taxable income are reduced.

As of December 31, 2010, tax loss carryforwards amounted to RMB38,257 (US$5,797),
of which RMB5,998 and RMB32,259 will expire if unused by the years ending December 2014 and 2015, respectively.

The Company
has not provided for income taxes on accumulated earnings amounting RMB301,990 that are subject to the PRC dividend withholding tax as of December 31, 2010, since these earnings are intended to be permanently reinvested. The amount of
unrecognized deferred income tax liability is approximately RMB15,100.

As of January 1, 2008 and for each of the years
ended December 31, 2008, 2009 and 2010, the Group did not have any unrecognized tax benefits and accordingly no related interest and penalties have been recorded. The Group does not expect that the amount of unrecognized tax benefits will
increase significantly within the next 12 months.

According to the PRC Tax Administration and Collection Law, the statute of
limitation is three years if the underpayment of taxes is due to computation errors made by the taxpayer or the withholding agent. The statute of limitation is extended to five years under special circumstances, where the underpayment of taxes is
more than RMB100 (US$15). In the case of transfer pricing issues, the statute of limitation is ten years. There is no statute of limitation in the case of tax evasion. Accordingly, the income tax returns of the Groups operating subsidiaries in
the PRC are open to examination by the PRC state and local tax authorities for the tax years beginning in 2005.

of the shares currently held by the shareholders, provided that the balance of the statutory surplus reserve after such issue is not less than 25% of the registered capital.

During the years ended December 31, 2008, 2009 and 2010, the Groups potential dilutive shares
outstanding consist of employee share options. In computing diluted earnings per share for the years ended December 31, 2008, 2009 and 2010, the dilutive effect of outstanding share options was computed by applying the treasury stock method
based on the difference between the ordinary shares assumed to be issued upon the exercise of the share options and the number of shares assumed to be purchased at the average estimated fair value during the period. The Company excluded 13,652,500,
49,025,000 and 27,272,500 potential ordinary shares issuable upon exercise of employee share options in the calculation of diluted earnings per share for the year ended December 31, 2008, 2009 and 2010, as their effect would be anti-dilutive.

(17) SHARE-BASED COMPENSATION

Share options

On January 1, 2008, the Board of Directors approved the adoption of the 2008 Share Incentive Plan (the 2008 Plan) to provide additional incentives to the Companys executives and
employees. The Plan provides for the grant of options, restricted shares, and restricted share units. The Plan authorizes grants to purchase up to 180,000,000 ordinary shares. Share options granted become exercisable over four years. The Company is
expected to issue new shares to satisfy share option exercises.

Under the 2008 Plan, the Company granted 13,555,000
unconditional share options and 13,555,000 conditional share options on January 1, 2008 and 22,700,000 unconditional share options and 900,000 conditional share options on June 30, 2008, respectively, to several of its executives and
employees.

On May 7, 2010, the Board of Directors of the Company approved the grant of an aggregate of 24,497,500
unconditional share options. On the same date, the Company granted 12,277,500 unconditional share options in exchange for the 12,277,500 conditional share options previously granted under the 2008 Plan (the Modification). In addition, on
the same date, the Company granted 12,220,000 share options to executives and employees who did not participate in the 2008 Plan.

The Modification was treated as an exchange of the original conditional share options award for the unconditional share options award at the date of modification. There was no significant difference
between fair value of the new unconditional options and that of the original conditional option awards immediately before the modification.

Unconditional Share Options Awards

The unconditional share options granted in 2008 and 2010 have an exercise price of RMB0.55, vest over 4 to 5 years of continuous service, and expire in 10 years from the date of grant. The share options
provide for accelerated vesting if there is a change in control (as defined in the 2008 Plan). Compensation cost is recognized over the requisite service period for each tranche based on a graded vesting schedule.

The fair value of each option award is estimated on the date of grant using a lattice option-pricing model based on the assumptions in
the following table:

(Amounts expressed in thousands, except share and per share data)



Prior to the IPO (since the Company did not have a trading history at the time the
options were issued) and subsequent to the Companys IPO (due to lack of sufficient historical trading record) the expected volatility was based on the historical volatilities of comparable publicly traded companies engaged in a similar
industry.

The Company uses historical data to estimate employee termination within the valuation model.

Prior to the IPO, the estimated fair value of the underlying ordinary shares on each date of grant was determined by management based on
a contemporaneous valuation conducted by an independent valuation firm, supplemented by the Companys estimate of Enterprise Value (EV).

The Companys EV was estimated using the discounted cash flows analysis (income approach). For the income approach, the Companys terminal value projected cash flows that are based
on five-year financial projections which were discounted to the respective valuation dates of January 1, 2008 and June 30, 2008 by the weighted average cost of capital (WACC) of 15.10% and 15.44%, respectively. The WACC used
was the combined result of the changes in risk-free rate and industry average beta and company specific risks.

The estimated
EV of the Company from the above calculation was then adjusted for a lack-of-marketability discount rate of 15% and 12% for the valuation date of January 1, 2008 and June 30, 2008, respectively, to reflect the fact that the Company was a
private company at that time. The discounted EV was then allocated to the Companys ordinary shares.

The fair value of
the shares underlying the options on the date of grant subsequent to the IPO has been based on the closing price of the ordinary shares listed on the New York Stock Exchange for the trading day prior to the grant date.

A summary of share option activity during the years ended December 31, 2008, 2009 and 2010 is as follows:

As of December 31, 2010, there was RMB6,749 total unrecognized compensation cost related to non-vested
share options under the Unconditional Share Options Awards. This cost is expected to be recognized over a weighted average period of approximately 3.5 years. RMB6,600 reversal of share-based compensation cost was recorded in 2010 in relation to
forfeiture of unvested share options due to the resignation of certain employees and executives.

Conditional Share Options Awards

The Conditional Share Options Awards were granted at an exercise price equal to 88% of the fair market value of the
Companys shares on the respective vesting date. Such options vest over four years of continuous service with 25% of the options to be vested on each of the first, second, third and fourth anniversaries of the grant date and expire in 10 years.
The vesting of share options under Conditional Share Options Awards is contingent upon the Group meeting revenue growth of at least 20% in the most recent fiscal year prior to each vesting date and the Group achieving a compounded annual growth rate
in total revenues of at least 20% from the fiscal year 2007 through the most recent fiscal year prior to each vesting date. In addition, the Compensation Committee determines on its sole discretion that the grantee has met all employee performance
criteria appropriate to merit the vesting of each tranche.

The fair value of each share option granted under the Conditional
Share Options Awards was estimated on the date of grant using the same option pricing model used for share options granted under the Unconditional Share Options Awards and assumes the performance goals will be achieved. If such goals are not met, no
compensation cost is recognized. The inputs used in estimating the fair value of share options granted under the Conditional Share Options Awards are the same as those noted in the table related to share options issued under the Unconditional Share
Options Awards for expected volatility, expected dividends, and risk-free interest rate. The expected term for share options granted under the Conditional Share Options Awards was adjusted by an early exercise factor based on managements
estimates.

As the employees are required to provide the service to earn the award, but there has not been a mutual
understanding of the terms of the award as to the exercise price until each vesting date of each tranche, the service inception date precedes the grant date. The fair value of the share option issued under Conditional Share Options Awards is
remeasured at each reporting date using a lattice option-pricing model until the grant date occurs.

The Conditional Share
Options Awards was cancelled by the Modification on May 7, 2010 as described above.

As a result of the Group deriving significant revenues from sales outside the PRC, the Groups
financial performance could be affected by events such as changes in foreign currency exchange rates, trade protection measures, changes in regional or worldwide economic or political conditions.

Management currently expects that the Groups operating results will, for the foreseeable future, continue to depend on the sale of
its compound chemical products to a relatively small number of customers. The Groups business is affected by competition in the market for the products that many of the Groups major customers sell, and any decline in their businesses
could reduce purchase orders from these customers. These customers have sought, from time to time, to prospectively renegotiate the pricing terms of their current agreements with the Group or obtain more favorable terms upon renewal of the
contracts. Any adverse revisions to the material terms of the Groups agreements with its key customers could have a material adverse effect on its business and results of operations.

Business and economic risks

The Group operates in a dynamic industry with limited operating history and believes that changes in any of the following areas could have
a material adverse effect on the Groups future financial position, results of operations or cash flows: advances and new trends in new technologies and industry standards; competition from other competitors; changes in certain strategic
relationships or customers relationships; regulatory factors; the ability to obtain necessary financial and other resources at commercially viable terms; the ability to attract and retain employees necessary to support the Groups growth
and general risks associated with the industry.

The Group conducts its principal operations in the PRC and accordingly is
subject to significant risks. These include risks associated with, among others, the political, economic, legal environment and social uncertainties in the PRC, government agencies influence over certain aspects of the Groups operations
and competition in the industry.

In addition, the ability to negotiate and implement specific business development projects
in a timely and favorable manner may be impacted by political considerations unrelated to or beyond the control of the Group. Although the PRC government has been pursuing economic reform policies for the past two decades, no assurance can be given
that the PRC government will continue to pursue such policies or that such policies may not be significantly altered. There is also no guarantee that the PRC governments pursuit of economic reforms will be consistent or effective and as a
result, changes in the rate or method of taxation and changes in state policies may have a negative impact on the Groups operating results and financial position.

|(v) | The Group leased its plant and equipment to Shanghai Ambiopharm in 2008, 2009 and 2010. The carrying value of the plant and equipment amounted to RMB9,050 and RMB8,153
(US$1,235) as of December 31, 2009 and 2010, respectively. The initial lease term was two years and was renewed for an additional two-year period in June 2010. The annual lease receivable is RMB913 and Shanghai Ambiopharm paid RMB 873 in 2010.

|(vi) | The Group acquired 100% of the equity interest in Kangpeng Nong Hua in November 2009 for cash consideration of RMB25,000. Since the Company and Kangpeng Nong Hua were
under the common control of Dr. Yang on the date of the acquisition, it was accounted for in a manner similar to a pooling-of-interests. Accordingly, the financial statements of Kangpeng Nong Hua were consolidated by the Company at their
reported historical amounts and combined retrospectively to October 8, 2008, which is the earliest date that both entities were under common control (See Note 20 (c)).

(20) ACQUISITIONS

(a) Acquisition of a subsidiary

On February 2, 2008, upon receiving regulatory approval, the Group completed its acquisition of an 80% equity
interest in Jiangsu Wei Er from independent third parties for cash consideration of RMB4,000.

The acquisition of Jiangsu Wei
Er was accounted for using the purchase method in accordance with FASB Statement No. 141, Business Combinations, (SFAS No. 141). The results of Jiangsu Wei Ers operations have been included in the consolidated financial
statements since that date. The principal activities of Jiangsu Wei Er are sales and manufacturing of chemical compounds. The excess over the fair value of the net assets acquired (goodwill) was mainly due to expected benefits from expansion of the
Groups production capacity and securing Jiangsu Wei Ers existing product for the production of the Groups advanced-technology new products. The goodwill is not deductible for tax purposes.

Management made estimates and judgments in determining the fair values of the assets acquired and liabilities assumed based on
independent appraisal reports as well as its experience in valuation of similar assets and liabilities.

The allocation of the
purchase price to 80% of the fair value of net assets of Jiangsu Wei Er on February 2, 2008 is as follows:



|                              |  |     |         |

|Purchase price                |  |     | 4,000   |

from 60% to 80%, for cash consideration of RMB8,000. The consideration was paid in full in August 2008. The acquisition of the additional equity interests was accounted for using the purchase method in accordance with SFAS No. 141. The goodwill
is not deductible for tax purposes.

Management makes estimates and judgments in determining the fair value of the assets
acquired and liabilities assumed based on independent appraisal reports as well as its experience in valuation of similar assets and liabilities.

The allocation of the purchase price to 20% of the fair value of net assets of Huajing Company on March 25, 2008 is as follows:



|                              |  |     |        |

Jiangsu Wei Er

On November 5, 2009, the Group acquired the remaining 20% equity interest in Jiangsu Wei Er from the noncontrolling shareholder, which increased the Companys equity interest from 80% to 100%,
for cash consideration of RMB41,000. In accordance with FASB ASC Subtopic 810-10, Consolidation, which was effective for fiscal years beginning or after December 15, 2008, the excess of cash consideration over the carrying amount of the
noncontrolling interest of RMB7,953 was recognized as a decrease in additional paid-in capital attributable to Chemspec International Limited shareholders in the statement of equity and comprehensive income for the year ended December 31, 2009.

(c) Acquisition of a company under common control

On November 9, 2009, the Group acquired 100% of the equity interest of Kangpeng Nong Hua for cash consideration of RMB25,000. As
Dr. Yang held more than 50% voting ownership interest of both the Company and Kangpeng Nong Hua at the date of the acquisition, it is considered a combination of entities under common control and has been accounted for in a manner similar to a
pooling-of-interests. Accordingly, the financial statements of Kangpeng Nong Hua have been consolidated by the Company using their reported historical amounts and combined retrospectively to October 8, 2008, which is when Dr. Yang obtained
control of Kangpeng Nong Hua by increasing his effective equity interest in Kangpeng Nong Hua to 51.7%.

The acquisition of
51.7% equity interest for consideration of RMB12,925 is recognized by reducing additional paid-in capital attributable to Chemspec International Limited shareholders by RMB8,616 and the excess of cash consideration over additional paid-in capital of
RMB4,309 is recognized as a decrease to retained earnings.

In accordance with FASB ASC Subtopic 810-10, the excess of cash
consideration of RMB12,075 over the carrying amount of the noncontrolling interest of RMB4,940 was recognized as a decrease to additional paid-in capital attributable to Chemspec International Limited shareholders in the consolidated statement of
equity and comprehensive income for the year ended December 31, 2009.

Limiteds ownership in subsidiaries

Effect of the changes in the Companys ownership interest in its

On March 21, 2011, the
Companys Board of Directors approved an agreement of merger with Halogen Mergersub Limited (Mergersub), a Cayman Islands exempted company which is jointly controlled by Dr. Yang and Primavera Capital Management Ltd. in
response to the going private proposal letter issued by Dr. Yang on November 11, 2010. Under the terms of the agreement, Mergersub will be merged with and into the Company, with the Company being the surviving company and each ordinary
share of the Company issued and outstanding immediately prior to the effective time of the merger will be cancelled in exchange for the right to receive US$0.135 (or US$ 8.1 per ADS) in cash without interest (less $0.05 per ADS cancellation
fees payable to the ADS depositary), except for the ordinary shares beneficially owned by Dr. Yang, Mr. Yunlong Yuan and Mr. Weinian Qi, which will be cancelled without receiving any consideration. In addition, pursuant to the
agreement of merger, the Company needs to comply with a number of covenants, and any breach of these covenants will result in termination of the agreement and the Company paying a termination fee of US$3,000 (RMB equivalent 19,800).

(b) Japan Earthquake and Tsunami in March 2011

On March 11, 2011, an earthquake with a magnitude of 9.0 occurred in Japan. The earthquake was followed by a tsunami which damaged
multiple nuclear reactors at the Fukushima Daiichi Nuclear Power Station. These events have not had any impact on the Companys consolidated financial statements for the year ended December 31, 2010. During the year ended December 31,
2008, 2009 and 2010, the Groups sales to customers in Japan accounted for 18%, 28% and 31%, respectively, of the Groups revenue. The Group currently does not have any physical presence in Japan. To date, the Group has not experienced any
significant delay in customer orders or cash collection difficulties with its customers as a result of these March 11, 2011 events.
