We make no representation that any Renminbi or U.S. dollar amounts could have been, or could be,
converted into U.S. dollars or Renminbi, as the case may be, at any particular rate, the rates stated above, or at all. The PRC government imposes control over its foreign currency reserves in part through direct regulation of the conversion of
Renminbi into foreign exchange and through restrictions on foreign trade.

Risks Related To Our Company

We are
currently dependent on our flagship product, EPIAO. A reduction in revenues of EPIAO would cause our revenues to decline and could materially harm our business.

We are largely dependent on sales of our erythropoietin, or EPO, product, which we market under the name of EPIAO. We began marketing and selling EPIAO in 1998, and it has been our top-selling product since 2002.
Revenues from sales of EPIAO accounted for 83.1%, 77.3% and 67.3% of our total revenues for the years ended December 31, 2005, 2006 and 2007, respectively. We have continued our efforts to develop EPO products in 2007 and expect that sales of
EPIAO will continue to comprise a substantial portion of our revenues in the future.

Any reduction in revenues from EPIAO will have a
direct negative impact on our business, financial condition and results of operations. Our EPO franchise and associated revenues could be adversely affected by a variety of factors, including:



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



| |  |  | new product introductions;
| | - |  | --------------------------



| |  |  | government-imposed pricing constraints;
| | - |  | ---------------------------------------



| |  |  | intellectual property issues;
| | - |  | -----------------------------



| |  |  | problems with raw materials supply;
| | - |  | -----------------------------------



| |  |  | disruptions in manufacturing or distribution; and
| | - |  | -------------------------------------------------



| |  |  | newly discovered safety issues.
| | - |  | -------------------------------

Despite our efforts, we may be unable to develop or acquire new products that would enable us to diversify our business and reduce our dependence on EPIAO products.

The commercial success of our products depends upon the degree of market acceptance among the medical community. Failure to attain market acceptance among the medical community would have an adverse impact on
our operations and profitability.

The commercial success of our products depends upon the degree of market acceptance they achieve
among the PRC medical community, particularly physicians and hospitals. Physicians may not prescribe or recommend our products to patients, and procurement departments of hospitals may not purchase our products. The acceptance of any of our products
among the medical community will depend upon several factors, including:



| |  |  | the safety and effectiveness of the product;
| | - |  | --------------------------------------------



4



---

| |  |  | the effectiveness of our efforts to market our products to hospitals and physicians;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | the products cost effectiveness;
| | - |  | ---------------------------------



| |  |  | the products perceived advantages and disadvantages relative to competing products or treatments; and
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | the prevalence and severity of side effects.
| | - |  | --------------------------------------------

If our products fail to attain market acceptance among the medical community, our operations and profitability would be adversely affected.

The selling prices of our products tend to decline over time. Our success depends on our ability to successfully develop and commercialize additional pharmaceutical products. Our product development efforts may not result in
commercially viable products.

As is typical in the Chinese pharmaceutical industry, the average selling prices of our products tend
to decline significantly over the life of the product. These declines principally result from increased competition and changes in government policies. For example, from 2004 to 2005 the average selling price of Intefen declined by 20%. Also, the
recent policies of National Drug Reform Committee, or the NDRC, required that we lower prices on our higher dosage EPIAO, which we had previously sold at a premium.

We must therefore constantly identify product candidates that can be developed into cost-effective therapeutic products. We plan to continue to invest in research and development; however, successful product
development in our industry is highly uncertain, and relatively few research and development projects produce commercially viable products. If we cannot offset any decline in revenues and margins of our marketed products with new product
introductions, our overall results of operations will be materially and adversely affected.

Our products face substantial competition. Other
companies may discover, develop, acquire or commercialize products before or more successfully than we do.

We operate in a highly
competitive environment. Our products compete with other products or treatments for diseases for which our products may be indicated. EPIAO competes with both existing EPO drugs and potential new drug candidates. In China, EPO drugs are offered by
established international companies such as Kirin Brewery Company Limited, or Kirin, and F. Hoffmann-La Roche, Ltd., or Roche, and domestic pharmaceutical companies such as Diao Group Chengdu Diao Jiuhong Pharmaceutical Factory. Competitors
for interferon alpha-2 drugs include Schering-Plough (Brinny) Co. and Beijing Tri-Prime Genetic Engineering Co., Ltd., and competitors for interleukin-2 include Beijing SL Pharmaceutical Co., Ltd. and Beijing Four Rings Biopharmaceutical Co., Ltd.
Competitors for Tietai Iron Sucrose Supplement include Beijing Novartis Pharmaceutical Co., Ltd. and Nanjing Hencer Pharmaceutical Co., Ltd. In addition, while we believe TPIAO, our newest internally developed protein-based therapeutic product, is
the only recombinant human thrombopoietin, or TPO-based therapeutic available in the Chinese market to date, we are aware of another Chinese pharmaceutical company, Shanghai CP Guojian Pharmaceutical Company Limited, or CP Guojian, which we believe
may be conducting clinical trials for a TPO-based therapeutic in China. If CP Guojian had obtained the approval for any clinical trials prior to May 2005, the commencement of the monitoring period for TPIAO, CP Guojian may not be prohibited from
manufacturing and marketing its TPO product during TPIAOs monitoring period. Our products may compete against products that have lower prices, superior performance, greater ease of administration or other advantages compared to our products.
We do not have patents of any commercial significance covering EPIAO, our legacy products or many of our other product candidates with which to protect these products from direct competition. Our inability to compete effectively could reduce sales
or margins, which could have a material adverse effect on our results of operations.

Certain of our competitors, including biotechnology
and pharmaceutical companies, market products or are actively engaged in research and development in areas where we have products or where we are developing

product candidates or new indications for existing products. In the future, we expect that our products will compete with new drugs currently in development,
drugs approved for other indications that may be approved for the same indications as those of our products and drugs approved for other indications that are used off-label. If less invasive or less expensive alternatives to our products are
dispensed or prescribed to patients, our sales could be adversely affected. An increasing number of foreign pharmaceutical companies have also introduced their pharmaceutical products into the Chinese market.

As we expand our product portfolio by adding new products and indications, as well as developing second-generation versions of existing products with the
same or overlapping labels, certain of our products may be used as a substitute for our other products in the same end markets. For instance, although EPIAO and TPIAO are targeted toward patients with different indications and TPIAO is not intended
to replace EPIAO in the oncology market, some doctors may prescribe TPIAO for their patients when they would have otherwise prescribed EPIAO. Consequently, the introduction of TPIAO may adversely affect sales of EPIAO.

Large Chinese state-owned and privately-owned pharmaceutical companies and foreign pharmaceutical companies may have greater clinical, research,
regulatory, manufacturing, marketing, financial and human resources than we do. In addition, some of our competitors may have technical or competitive advantages over us for the development of technologies and processes. These resources may make it
difficult for us to compete with them to successfully discover, develop and market new products and for our current products to compete with new products or new product indications that these competitors may bring to market. There may also be
significant consolidation in the pharmaceutical industry among our competitors, alliances may develop among competitors and these alliances may rapidly acquire significant market share.

Furthermore, in order to gain market share in China, competitors may significantly increase their advertising expenditures and promotional activities or
engage in irrational or predatory pricing behavior. In addition, our competitors may engage in illegal acts, such as bribery. Third parties may actively engage in activities designed to undermine our brand name and product quality or to influence
customer confidence in our products. Increased competition may result in price reductions, reduced margins and loss of market share, any of which could materially adversely affect our profit margins. We may not be able to compete effectively against
current and future competitors.

Our competitors may have the ability to manufacture pharmaceutical products substantially similar to ours.

Our ability to compete against our competitors is, to a significant extent, dependent upon our ability to distinguish our products from
those of our competitors by providing high quality products at reasonable prices that are perceived to be safe and effective by doctors and patients. Many of our competitors may have been in business longer than we have, may have substantially
greater financial and other resources than we have and may be better established in our markets. Our competitors in any particular market may also benefit from raw material sources or production facilities that are closer to such markets, which may
provide them with competitive advantages in terms of cost and proximity to consumers.

We have a monitoring period for TPIAO through May
2010, during which other pharmaceutical companies are prohibited from manufacturing or importing similar drugs, except those whose applications for clinical trials were approved by the SFDA prior to May 2005, the commencement of TPIAOs
monitoring period. Upon expiration of the monitoring period, other manufacturers in China may apply for approval by the SFDA to manufacture such product using similar formulae or production techniques. If other manufacturers introduce the same
product or products substantially similar to ours, we will face more competitive pressure in the market and our sales and profit margin may be adversely affected.

Our business depends on our Shenyang Sunshine and EPIAO brands, and if we are not able to maintain and enhance our
brands to maintain our competitive advantage, our reputation, business and operating results may be harmed.

We believe that market
awareness of our Shenyang Sunshine and EPIAO brands has contributed significantly to the success of our business. We also believe that maintaining and enhancing the Shenyang Sunshine and EPIAO brands is critical to maintaining our competitive
advantage. In order to further penetrate our markets and launch new products, we must expand our manufacturing and sales and marketing efforts. Maintaining quality and cost-effectiveness may be more difficult to achieve.

While our sales and marketing staff will continue to further promote our brand to remain competitive, we may not be successful. If we are unable to
further enhance our brand recognition and increase awareness of our products, or if we incur excessive marketing and promotion expenses, our business and results of operations may be materially and adversely affected.

Certain of our raw materials, medical devices and components are single-sourced from third parties; third-party supply failures could adversely affect our ability
to supply our products.

Certain raw materials necessary for commercial manufacturing and formulation of our products are provided
by single-source unaffiliated third-party suppliers. Also, certain medical devices and components necessary for formulation, fill, and finish of our products are provided by single-source unaffiliated third-party suppliers, including the EPO Elisa
Kit by R&D Systems Inc., GIBCO cell culture medium by Invitrogen Inc., Pharmacia EPO chromatography purification medium by GE Healthcare, a division of GE, and Disc, a microcarrier for cell cultures, by New Brunswick Scientific Inc. For more
details, see Item 4. Information on the CompanyB. Business OverviewManufacturing. Certain of these raw materials, medical devices and components are the proprietary products of these unaffiliated third-party suppliers.

We would be unable to obtain these raw materials, medical devices or components for an indeterminate period of time if these third-party
single-source suppliers were to cease or interrupt production or otherwise fail to supply these materials or products to us for any reason, including due to regulatory requirements or action, due to adverse financial developments at or affecting the
supplier, and/or due to unexpected demand, labor shortages or disputes. We would also be unable to obtain these materials, devices and components for an indeterminate period of time if such supply was subsequently found to not be in compliance with
our quality standards or resulted in quality failures or product contamination and/or recall when used to manufacture, formulate, fill or finish our products. These events could adversely affect our ability to satisfy demand for our products, which
could materially and adversely affect our product sales and operating results.

For example, we have occasionally experienced shortages in
certain components necessary for the formulation, fill and finish of certain of our products in our Shenyang facility without impact on our ability to supply these products. However, we may experience shortages in the future resulting in delayed
shipments, supply constraints, stock-outs and/or recalls of our products, which could result in interruptions to our production.

We depend on our
distributors for sales of our products.

We rely on our network of approximately 150 distributors to distribute our own and our
in-licensed products. Our distributors do not sell our products on an exclusive basis. As a result, our products face competition from similar products sold by our distributors.

Our success will depend in part on our ability to form relationships with and manage an increasing number of distributors. If our distribution network in
China suffers a disruption, our financial condition and results of operations may be adversely affected.

While we have long-standing business relationships with most of our distributors and we have not, in the
past three years, lost any significant distributors, we do not have long-term contracts with any distributor. Moreover, a significant amount of our revenue is generated by product sales to relatively few distributors, whose mix changes from year to
year. The tables below set forth the aggregate sales to our top five distributors, expressed in RMB and as a percentage of our total sales, for the periods indicated.

If any one of these distributors were to voluntarily or involuntarily suspend or terminate product
purchases from us, we would need to divert product sales to other distributors, which could cause short-term disruptions to our revenues and profitability.

If we fail to achieve specified sales goals with respect to an in-licensed product, the license agreement relating to that product may be terminated and our results of operations may suffer.

We have recently begun to distribute third-party products pursuant to in-licensing agreements with domestic pharmaceutical corporations. For example, we
currently in-license Tietai Iron Sucrose Supplement and Baolijin,

---

a granulocyte colony-stimulating factor. If we fail to achieve certain sales targets, our licensing agreement in relation to Tietai Iron Sucrose Supplement
with Shenyang Borui Pharmaceutical Company Limited and Baolijin with Chengdu Institute of Biological Products will become terminable on short notice. Given these risks, there is substantial uncertainty regarding the success of our current and future
collaborative efforts.

We are highly dependent on senior management and key research and development personnel.

We are highly dependent on our senior management to manage our business and operations and our key research and development personnel for the development
of new technologies and applications and the enhancement of our existing products. In particular, we rely substantially on our chief executive officer, Dr. Jing Lou, to manage our operations. We also depend on our key research personnel such as
Ms. Dongmei Su, our chief technology officer. In addition, we also rely on sales personnel, and other personnel with industry knowledge, to market and sell our products. We do not maintain key man life insurance on any of our senior management
or key personnel. The loss of any one of them, in particular Dr. Lou, would have a material adverse effect on our business and operations. Although Dr. Lou and Ms. Su have each signed a non-competition agreement with us, we cannot
assure you that we will be able to successfully enforce these provisions in the event of a dispute.

Competition for senior management and
research and development personnel is intense, and the pool of suitable candidates is limited. We may be unable to locate a suitable replacement for any senior management or key research and development personnel that we lose. We compete for
qualified personnel with other pharmaceutical companies, universities and research institutions. Intense competition for these personnel could cause our compensation costs to increase significantly, which could have a material adverse effect on our
results of operations. Our future success and ability to grow our business will depend in part on the continued service of these individuals and our ability to identify, hire and retain additional qualified personnel. If we are unable to attract and
retain qualified employees, we may be unable to meet our business and financial goals.

Our future capital needs are uncertain. As a result, we may
need to raise additional funds in the future.

We may require additional cash resources in the future. Our future cash needs will
depend upon:



| |  |  | the extent to which our products are accepted in the market and generate cash flows;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | the resources we devote to developing, marketing and producing our products;
| | - |  | ----------------------------------------------------------------------------



| |  |  | the receipt of, and the time and expenses required to obtain and maintain, regulatory clearances and approvals;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | our ability to identify and our desire or need to pursue acquisitions or other investments; and
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | changed business conditions or other future developments.
| | - |  | ---------------------------------------------------------

Our revenues may not be sufficient to meet our operational needs and capital requirements, and needed financing may not be available in amounts or on terms acceptable to us, if at all. Our future capital needs and
other business reasons could require us to sell additional equity or debt securities or obtain a credit facility. The sale of additional equity or equity-linked securities could result in dilution to our shareholders. The incurrence of indebtedness
would result in increased debt service obligations and could result in operating and financing covenants that would restrict our operations or our ability to pay dividends to our shareholders. Moreover, credit arrangements in the PRC are subject to
government restrictions and may not be available to us on commercially reasonable terms or at all.

We may not achieve our projected development
goals in the time frames we announce and expect.

We set goals for, and made disclosures in this annual report regarding, timing of
the accomplishment of objectives material to our success, such as the commencement and completion of clinical trials, anticipated



9



---

regulatory submission and approval dates and timing of product launches. As a public company listed in the United States, we make additional announcements in
our public reports and in press releases regarding these events, from time to time. The actual timing of these events can vary dramatically due to factors beyond our control, such as delays or failures in our clinical trials, the uncertainties
inherent in the regulatory approval process and delays in achieving manufacturing or marketing arrangements sufficient to commercialize our products. There can be no assurance that our clinical trials will be completed, that we will make regulatory
submissions or receive regulatory approvals as planned or that we will be able to adhere to our current schedule for the launch of any of our products. If we fail to achieve one or more of these milestones as planned, the price of our shares could
decline.

If we are unable to protect our products through intellectual property rights, our competitors may compete directly against us.

Our success depends, in part, on our ability to protect our products from competition by establishing, maintaining and enforcing
intellectual property rights. We try to protect the products and technology that we consider important to our business by filing PRC patent applications, relying on trade secrets or pharmaceutical regulatory protection or employing a combination of
these methods. We do not have any patent protection of commercial significance relating to EPIAO. We have patents and patent applications relating to TPIAO and certain of our other products, product candidates and technologies. For more details, see
Item 4. Information on the CompanyB. Business OverviewIntellectual Property. However, the process of seeking patent protection in the PRC can be lengthy and expensive, and we cannot assure you that these patent applications,
or any patent applications we may make in the future in respect of other products, will result in patents being issued, or that any patents issued in the future will be able to provide us with meaningful protection or commercial advantage. Our
patent applications may be challenged, invalidated or circumvented in the future. For more details on the process for applying for and obtaining intellectual property protection in the PRC, see Item 4. Information on the CompanyB.
Business OverviewRegulationsPRC patent law and Trademark.

In addition to patents, we rely on trade
secrets and proprietary know-how to protect our intellectual property. We have entered into confidentiality agreements with many of our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors. These
agreements may not provide meaningful protection or adequate remedies in the event of unauthorized use or disclosure of our proprietary information. In addition, it is possible that third parties could independently develop proprietary information
and techniques substantially similar to ours or otherwise gain access to our trade secrets.

We may become involved in patent litigation
against third parties to enforce our patent rights, to invalidate patents held by such third parties, or to defend against such claims. The cost to us of any patent litigation or similar proceeding could be substantial, and it may absorb significant
management time. We do not maintain insurance to cover intellectual property infringement.

Intellectual property rights and
confidentiality protections in China may not be as effective as in the United States or other countries, due to, among other reasons, lack of procedural rules for discovery and evidence, low damage awards and lack of judicial independence.
Implementation and enforcement of PRC intellectual property-related laws have historically been deficient and ineffective and may be hampered by corruption and local protectionism. Policing unauthorized use of proprietary technology is difficult and
expensive, and we might need to resort to litigation to enforce or defend patents issued to us or to determine the enforceability, scope and validity of our proprietary rights or those of others. The experience and capabilities of PRC courts in
handling intellectual property litigation varies, and outcomes are unpredictable. Further, such litigation may require significant expenditure of cash and management efforts and could harm our business, financial condition and results of operations.
An adverse determination in any such litigation could materially impair our intellectual property rights and may harm our business, prospects and reputation.

We depend on administrative protection and monitoring periods for certain of our products, which afford us less
protection than patents.

Prior to the 1990s, Chinese pharmaceutical companies were not capable of producing innovative drugs due to
financial and technical obstacles. Under Chinas first patent law enacted in March 1984, drugs were not eligible for patent protection. This law, however, provided patent protection for the manufacturing methods of pharmaceuticals. The Drug
Administration Law of 1984 specified that pharmaceutical products that had never been manufactured in China were classified as new drugs, and allowed Chinese pharmaceutical companies to produce drugs that are similar in structure and function to
foreign drugs so long as the foreign drugs had not been manufactured inside China. To further protect the domestic pharmaceutical industry, in 1999 the SFDAs predecessor, the State Drug Administration, issued the Regulation on New Drug
Protection and Related Technology Transfer, or the 1999 Regulations, which provided a six to twelve year administrative protection period for five categories of new drugs. In December 2002, the 1999 Regulations were replaced by the Administrative
Measures on the Registration of Pharmaceutical Products, or the 2002 Regulations, which were later revised in February 2005. According to the 2002 Regulations, with a view to protecting public health, the SFDA may provide for administrative
monitoring periods of up to five years for new drugs approved to be manufactured, to continually monitor the safety of those new drugs. The key element in determining the availability and duration of the monitoring period is the safety of the new
drug. The SFDA will consider, among other things, whether the new drug has been previously launched domestically or overseas, what type of new drug it is and what process and technology are involved in the production of the new drug. For example,
for a biochemical product that has never been launched domestically or overseas, a five-year monitoring period will be granted; for a biochemical product that has been launched overseas but not domestically, only a four-year monitoring period will
be granted.

We have administrative protection for TPIAO through 2010 under a five-year monitoring period pursuant to the 2002 Regulations,
during which other pharmaceutical companies are prohibited from manufacturing or importing similar drugs, except those whose applications for clinical trials were approved by the SFDA prior to May 2005, the commencement of TPIAOs monitoring
period. For a detailed discussion of the mechanism for administrative protection under the relevant Chinese regulations, please refer to Item 4. Information on Our CompanyB. Business OverviewRegulationsAdministrative
protection and monitoring periods for new drugs.

The period of administrative protection under these Chinese pharmaceutical
regulations is considerably shorter than the exclusivity period afforded by patent protection, which, in the case of invention patents, may last up to 20 years from the national filing date of the patent directed to the product, its use or method of
manufacture. Once the monitoring period expires, all third parties will be free to compete with us, unless we can exclude them from the market through patents or other intellectual property rights.

In addition, the administrative protection for EPIAO in relation to the indication of anemia associated with chemotherapy in cancer patients with
non-myeloid malignancies cannot always prevent off label use of other EPO drugs for this indication. If physicians substitute similar or less expensive drugs for EPIAO, our revenues and financial condition will be adversely affected.

In addition, the PRC government has in the past, and may in the future, change the duration of the monitoring period. If this occurs, we may lose the
administrative protection for our new products or the protection period may be shortened, and we may lose advantage over our competitors with respect to our new products.

If our products infringe the intellectual property rights of third parties, we may incur substantial liabilities, and we may be unable to sell these products.

Our commercial success depends significantly on our ability to operate without infringing the patents and other proprietary rights of third parties. Under
the PRC Patent Law promulgated by the Peoples Congress in March 1984 and later revised in September 1992 and August 2000, patent applications are maintained in



11



---

confidence until their publication 18 months from the filing date. The publication of discoveries in the scientific or patent literature frequently occurs
substantially later than the date on which the underlying discoveries were made and patent applications are filed. China adopts the first-to-file system under which whoever first files a patent application (instead of the one who makes first actual
discoveries) will be awarded the patent. By contrast, the United States patent law endorses the first-to-invent system under which whoever makes the first actual discovery will be awarded the patent. Under the first-to-file system, even after
reasonable investigation we may not know with certainty whether we have infringed a third partys patent because such third party may have filed a patent application without our knowledge while we are still developing that product. We are aware
of intellectual property rights held by third parties that relate to products or technologies we are developing. For example, we are aware of a patent held by a third party that may relate to our TPIAO product. We believe, as to each claim in this
patent, that we either do not infringe the claim of the patent or that the claim is invalid. While the validity of issued patents, patentability of pending patent applications and applicability of any of them to our programs are uncertain, if
asserted against us, any related patent rights could adversely affect our ability to commercialize our products.

If a third party claims
that we infringe its proprietary rights, any of the following may occur:



| |  |  | we may become involved in time-consuming and expensive litigation, even if the claim is without merit;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | we may become liable for substantial damages for past infringement if a court decides that our technology infringes a third partys patent;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a court may prohibit us from selling or licensing our product without a license from the patent holder, which may not be available on commercially acceptable terms,
if at all, or which may require us to pay substantial royalties or grant cross licenses to our patents; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may have to reformulate our product so that it does not infringe patent rights of others, which may not be possible or could be very expensive and
time-consuming.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------

Although to date we have not experienced any of the circumstances listed above, if any of these events
occurs, our business will be adversely affected and the market price of our American depositary shares, or ADSs, could decline.

Failure to implement
our growth and expansion strategy could result in deterioration in our results of operations and financial condition.

In order to
achieve our internal forecasts, we must successfully implement our growth and expansion strategy. To do so, we must:



| |  |  | expand our capacity by further process optimization and new facility construction;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | continue our research and development efforts to introduce new and more advanced products;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | promote domestic marketing and sales development and growth;
| | - |  | ------------------------------------------------------------



| |  |  | expand the number, and enhance the expertise in U.S. GAAP financial reporting, of our finance staff;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | implement our strategy to bifurcate our sales force in the nephrology and oncology areas;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | maintain and further improve our manufacturing process and proprietary technologies to manufacture products with high quality and competitive prices; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | integrate any new businesses, technologies and products that we acquire by way of in-licensing, acquisitions or investments into our operations.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------

If we do not successfully implement this strategy, we may not be able to maintain our growth in revenues and
profitability, and the market price for our ADSs will suffer.

We have grown steadily since our establishment in 1993. This expansion presented, and our anticipated
growth in the future will continue to present, a significant challenge to our management and administrative systems and resources. If we do not adequately manage this challenge, our results of operations and financial condition could suffer.

We are building European Medicines Agency, or EMEA, and Chinese current Good Manufacturing Practice, or GMP, compliant manufacturing
facilities in Shenyang to take advantage of the market opportunity we believe exists in Europe and other selected regulated markets for new versions of biopharmaceutical products whose patents have expired (known as biosimilar products). Similar to
the US FDA, the EMEA is a European agency for the evaluation of medicinal products. GMP refers to guidelines and regulations issued from time to time pursuant to PRC laws as part of quality assurance to ensure that products subject to those
guidelines and regulations are consistently produced and controlled to the quality and standards appropriate for their intended use. Substantial capital and management resources will be required in order to complete the construction of the
manufacturing facilities on time, secure regional partnerships, seek regulatory approvals and promote our brand. We may be unable to successfully execute the expansion plan due to a delay in obtaining a GMP certificate for our new manufacturing
facilities, inability to obtain suitable partners to assist us with our expansion plans, changing competitive dynamics of the European biosimilar market or inability to obtain approvals for selling our products in Europe. As a result, our
profitability may be adversely affected.

Power shortages, natural disasters, terrorist acts or other calamities could disrupt our production and
have a material adverse effect on our business, financial position and results of operations.

EPIAO, TPIAO and our legacy products
are produced at our manufacturing facilities in Shenyang. A significant disruption at that facility, even on a short-term basis, could impair our ability to produce and ship products on a timely basis, which could have a material adverse effect on
our business, financial position and results of operations.

Our Shenyang manufacturing operations are vulnerable to interruption and
damage from natural and other types of disasters, including earthquake, fire, floods, environmental accidents, power loss, communications failures and similar events. If any disaster were to occur, our ability to operate our business at our
facilities would be seriously impaired. In addition, the nature of our production and research activities could cause significant delays in our programs and make it difficult for us to recover from a disaster. We do not maintain any insurance other
than insurance for some of our properties. Accordingly, unexpected business interruptions resulting from disasters could disrupt our operations and thereby result in substantial costs and diversion of resources.

In addition, our production process requires a continuous supply of electricity. We have encountered power shortages twice in the past due to restricted
power supply to industrial users during summers when the usage of electricity is high and supply is limited or as a result of damage to the electricity supply network. Because the duration of those power shortages was brief, they had no material
impact on our operations. However, interruptions of electricity supply could result in lengthy production shutdowns, increased costs associated with restarting production and the loss of production in progress. Any major suspension or termination of
electricity or other unexpected business interruptions could have a material adverse impact on our business, financial condition and results of operations.

We may experience significant period-to-period quarterly and annual fluctuations in our revenues and operating results, which may result in volatility in our stock price.

We typically generate higher levels of revenues during the third and fourth quarters of the year, primarily because of the tendency of hospitals to place
more orders prior to the year-end holiday season and the fact that more people visit hospitals in the second half of the year, resulting in more prescriptions by physicians during this period. We may in the future experience significant
period-to-period fluctuations in our revenues and operating results. Our revenues and operating results in some quarters may fall below the estimates of securities

research analysts, which may cause the value of our ordinary shares and ADSs to decline. Our quarterly and annual operating results are affected by a number
of factors, such as:



| |  |  | seasonal spending patterns of Chinese consumers, including hospitals, dialysis centers and clinics;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | changes in pricing policies by us, our competitors or the government, an example of which is the one-time downward adjustment by the government of the price ceiling
for all interferon products in China in 1999;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the timing and market acceptance of new products and product enhancements by us or our competitors;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | the loss of key sales personnel or distributors;
| | - |  | ------------------------------------------------



| |  |  | our involvement in litigation;
| | - |  | ------------------------------



| |  |  | changes in government policies or regulations; and
| | - |  | --------------------------------------------------



| |  |  | a downturn in general economic conditions in China.
| | - |  | ---------------------------------------------------

While certain of the factors identified above, including seasonal spending patterns, changes in pricing policies, market acceptance of new products and changes in government policies, have in the past caused
fluctuations in our quarterly financial results, we have not suffered any material and adverse consequences from these fluctuations in the last three years. However, many of these factors are beyond our control, and you should not rely on our
results of operations for prior quarters as an indication of our results in any future period. As our revenues vary significantly from quarter to quarter, our business could be difficult to predict and manage and our quarterly results could fall
below investor expectations, which could cause our ADS price to decline.

We have previously operated as a private Chinese company and have little
experience in complying with requirements applicable to public companies in the United States. We have only relatively recently begun to prepare our financial statements in accordance with U.S. GAAP and continued compliance with these requirements
will continue to increase our costs and require additional management resources.

Historically, we have primarily prepared unaudited
financial statements in accordance with PRC GAAP for the purpose of tax reporting and determining the level of statutory reserves until our initial public offering. As a newly listed company, we have limited resources and a small finance and
accounting team. Although we have since invested additional resources and hired additional staff, we expect to continue to encounter substantial difficulty attracting qualified staff with requisite experience due to the high level of competition for
experienced financial professionals. In the short term, we are providing training for our current staff with respect to U.S. GAAP. Our training may not be sufficient or effective.

We continue to face increased legal, accounting, administrative and other costs and expenses as a public company that we did not incur as a private
company. Compliance with the U.S. Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, as well as other rules of the Securities and Exchange Commission, the Public Company Accounting Oversight Board and The NASDAQ Stock Market LLC, has resulted in
a significant initial cost to us as well as an ongoing increase in our legal, audit and financial compliance costs, including costs related to our compliance with Section 404 of the Sarbanes-Oxley Act which is described in the following risk
factor.

Failure to achieve and maintain effective internal controls could have a material adverse effect on the trading price of our ADSs.

We are subject to the reporting obligations under the United States securities laws, and beginning in this annual report on Form 20-F, we
are required by the Securities and Exchange Commission, as directed by Section 404 of the Sarbanes-Oxley Act, to include a report of management on the effectiveness of our internal control over financial reporting. In addition, beginning in the
annual report on Form 20-F for the year ending December 31, 2008, our independent registered public accounting firm must attest to and report on the effectiveness of our internal control over financial reporting. Although our management
concluded that our



14



---

internal controls are effective in this annual report on Form 20-F, our management may not conclude that our internal controls are effective in the future.
Moreover, even if our management concludes that our internal control over our financial reporting is effective, our independent public registered accounting firm may disagree. If our independent public registered accounting firm is not satisfied
with our internal control over financial reporting or the level at which our controls are documented, designed, operated or reviewed, it then may issue an adverse opinion on the effectiveness of our internal control over financial reporting. Any of
these possible outcomes could result in the loss of investor confidence in the reliability of our financial statements, which in turn could negatively impact the trading price of our ADSs.

Expiration of, or changes to, our tax incentives could have a material adverse effect on our operating results. There is also uncertainty associated with the
interpretation of new PRC Enterprise Income Tax Law

The PRC government has provided various incentives to high technology companies
in order to encourage development of the high technology industry and investments by foreigners. Such incentives include reduced tax rates and other measures. For example, as a high technology company operating in an approved economic- technological
development area, Shenyang Sunshine Pharmaceutical Company Limited, or Shenyang Sunshine, our main PRC operating subsidiary, is entitled to an enterprise income tax rate of 15%, compared to the 25% standard EIT rate under the new enterprise income
tax law described below. As a foreign-invested advanced technology enterprise certified by the relevant Chinese authorities, Shenyang Sunshine was entitled to a reduced tax rate of 10% for the year ended December 31, 2005. The 10%
rate expired after the taxable year ended December 31, 2005 and Shenyang Sunshines EIT was 15% for the years ended December 31, 2006 and 2007.

On March 16, 2007, the PRC Enterprise Income Tax Law, or the EIT Law, was enacted. Under the EIT Law, effective January 1, 2008, China adopted a uniform tax rate of 25% for all enterprises (including
foreign-invested enterprises) and revoked the then current tax exemption, reduction and preferential treatments applicable to foreign-invested enterprises. However, there is a transition period for enterprises, whether foreign-invested or domestic,
that were receiving preferential tax treatments granted by relevant tax authorities at the time the EIT Law became effective. Enterprises that are subject to an enterprise income tax, or EIT, rate lower than 25% may continue to enjoy the lower rate
and gradually transition to the new tax rate within five years after the effective date of the EIT Law. Enterprises that are currently entitled to exemptions or reductions from the standard income tax rate for a fixed term may continue to enjoy such
treatment until the fixed term expires. Preferential tax treatments will continue to be granted to industries and projects that are strongly supported and encouraged by the state, and enterprises otherwise classified as such encouraged
high-tech enterprises will be entitled to a 15% EIT rate. On April 14, 2008, the Measures for the Recognition and Administration of New and High-tech Enterprises, or the Measures, were promulgated jointly by the Ministry of Science and
Technology, the Ministry of Finance and the State Administration of Taxation and became retroactively effective from January 1, 2008. Under the Measures, the term high-tech enterprise is defined as a resident enterprise that has
been registered in the PRC (excluding Hong Kong, Macao or Taiwan) for more than one year, conducts business in the new and high-tech fields encouraged by government as listed in an appendix to the Measures, continuously undertakes research and
development and technology conversion, and relies on self-owned intellectual property rights as the basis of its business operation. Such new and high-tech enterprises may apply for tax incentives. There is no assurance that Shenyang Sunshine will
qualify as a new and high-tech enterprise under the Measures.

The EIT Law also provides that enterprises established outside of China
whose de facto management bodies are located in China are considered resident enterprises and will generally be subject to the uniform 25% EIT rate as to their global income, including income they receive from their
subsidiaries. Pursuant to the Implementation Rules to the Enterprise Income Tax law promulgated by State Council on December 6, 2007 and became effective on January 1, 2008 or the Implementation Rules, the term de facto management
bodies is defined as bodies that undertake overall management and control of the production, operation, human resource, finance, property and similar activities of the enterprise in material respects. Despite the Implementation Rules, it is
still not entirely clear under what situations an enterprises de facto management body is considered to be located in China. However, all of our management is currently based in China, and will likely remain in China



15



---

for the foreseeable future. In addition, although the EIT Law provides that dividend income between qualified resident enterprises is exempted
income, it is unclear what is considered a qualified 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 we may pay, if any, to our shareholders and ADS holders. Furthermore, unlike the PRC Income Tax Law for Enterprises with Foreign Investment and Foreign Enterprise (superseded by the EIT Law), which specifically
exempted withholding tax on any dividends payable to non-PRC investors, the EIT Law and the Implementation Rules provide that an income tax rate of 10% will normally be applicable to dividends payable to non-PRC investors which are derived from
sources within China, although such income tax may be exempted or reduced by the State Council. We are a Cayman Islands holding company and substantially all of our income may come from dividends we receive from our operating subsidiaries located in
China. If we declare dividends from such income, it is not clear whether it will be deemed to be derived from sources within China under the EIT Law and be subject to the 10% income tax. If we are required under the EIT Law to withhold income tax on
our dividends payable to our non-PRC shareholders and ADS holders, your investment in us may be materially and adversely affected.

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

We have historically received various government grants for our research and development programs. We recorded grant income of RMB3.8 million, RMB3.1 million and RMB1.1 million (US$0.1 million) in 2005, 2006 and 2007,
respectively. The grants in 2007 primarily relate to our research and development efforts on EPIAO and TPIAO. Even though we plan to continue to apply for grants and subsidies from the PRC government for our ongoing and future research and
development programs, there is no assurance that we will successfully obtain any level of grants and subsidies in future periods.

We may be
classified as a passive foreign investment company for United States federal income tax purposes, which could subject United States investors in the ADSs or ordinary shares to significant adverse tax consequences.

We may be classified as a passive foreign investment company, or a PFIC, for United States federal income tax purposes.

PFIC status is a factual determination made for each taxable year ending December 31, after the close of such year, on the basis of the composition
of our income and our active versus passive assets for such year. Under the PFIC rules, we will generally be classified as a PFIC if, in the case of any particular taxable year, 75% or more of our gross income consists of
certain types of passive income or 50% or more of the value of our assets consists of passive assets. For this purpose, cash and other liquid assets are generally classified as passive and goodwill and other unbooked
intangibles may generally be classified as active. The overall level of our passive assets will be significantly affected by the amount and time-frame within which we disperse the cash raised in our initial public offering, and other liquid assets
that we presently hold, for the purpose of the capital expenditures described in this annual report. In addition, the overall level of our active assets will depend, in great measure, on the valuation of our goodwill and other unbooked intangibles
as implied by our market capitalization which may decline.

We do not believe that we are currently a PFIC. However, because the PFIC
determination is highly fact intensive and made at the end of each taxable year, there can be no assurance that we will not be a PFIC for the current or any future taxable year or that the Internal Revenue Service will not challenge any
determination concerning our PFIC status. If we were to be or become classified as a PFIC, United States investors in our ADSs or ordinary shares may incur a significantly increased United States income tax liability on gain recognized on the sale
or other disposition of our ADSs or ordinary shares and on the receipt of distributions on our ADSs or ordinary shares. See the section entitled TaxationUnited States Federal Income Tax ConsiderationsPFIC Considerations.

Risks Related To Our Industry

The pharmaceutical industry in China is highly regulated, and future government regulation may place additional burdens on our business.

The pharmaceutical industry in China is subject to extensive government regulation and supervision. The regulatory framework addresses all aspects of operating in the pharmaceutical industry, including approval,
production, licensing and certification requirements and procedures, periodic renewal and reassessment processes, registration of new drugs and environmental protection. Violation of applicable laws and regulations may materially adversely affect
our business. In order to manufacture pharmaceutical products in China, we are required to apply for and obtain a pharmaceutical manufacturing permit from the provincial level food and drug administrative authority. In addition, in order to
manufacture and market any drug in China, we are required to apply for and obtain permits and certificates from the SFDA, including the new drug certificate, drug registration certificate (which includes the issuance of a drug approval number) and
GMP certificate. We are required to renew the pharmaceutical manufacturing permits, drug registration certificates and GMP certificates every five years. If we are unable to obtain or renew such permits or certificates or any other regulatory
approvals required for our operation, we will not be able to engage in the manufacture of our products and our business may be adversely affected.

The regulatory framework regarding the pharmaceutical industry in China is subject to change and amendment from time to time. Any such change or amendment may have an adverse effect on our business. Changes to the regulatory framework could
materially and adversely affect our business, financial condition and results of operations.

For further information regarding recent
changes in government regulations in China, see Item 4. Information on the CompanyB. Business OverviewRegulations.

New
product development in the pharmaceutical industry is both costly and labor-intensive and has a low rate of successful commercialization.

Our success will depend in part on our ability to enhance our existing products and to develop new products. The development process for pharmaceutical products is complex and uncertain, as well as time-consuming and costly. Relatively few
research and development programs produce a commercial product. A product candidate that appears promising in the early phases of development may fail to reach the market for a number of reasons, such as:



| |  |  | the failure to demonstrate safety and efficacy in preclinical and clinical trials;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | the failure to obtain approvals for intended use from relevant regulatory bodies, such as the SFDA;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | our inability to manufacture and commercialize sufficient quantities of the product economically; and
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | proprietary rights, such as patent rights, held by others to our product candidate and their refusal to sell or license such rights to us on reasonable terms, or at
all.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, product development requires the accurate assessment of market trends. We cannot assure you that:



| |  |  | our new product research and development efforts will be successfully and timely completed;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | the SFDA or other regulatory bodies will grant necessary regulatory clearances or approvals on a timely basis, or at all; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | any product we develop will be commercialized or achieve market acceptance.
| | - |  | ---------------------------------------------------------------------------

Delays in any part of the development process or our inability to obtain regulatory approval of our products could adversely affect our operating results
by restricting or delaying our introduction of new products. Even if we successfully commercialize new products, these products may address markets that are currently being served



17



---

by the off-label use of others of our mature products and inadvertently result in a reduction in the sales volume of our mature products or vice versa.
Failure to develop, obtain necessary regulatory clearances or approvals for or successfully commercialize or market potential new products or technologies could have a material adverse effect on our financial condition and results of operations.

We will not be able to commercialize our product candidates if our preclinical studies do not produce successful results or our clinical trials do
not demonstrate safety and efficacy in humans.

Before obtaining regulatory approvals for the manufacturing and sale of our product
candidates, we must conduct, at our own expense, extensive preclinical tests and clinical trials to demonstrate the safety and efficacy in humans of our product candidates. Preclinical and clinical testing is expensive, difficult to design and
implement, can take many years to complete and is uncertain as to outcome. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and interim results of a clinical trial do not
necessarily predict final results. A failure of one or more of our clinical trials can occur at any stage of testing. We may experience numerous unforeseen events during, or as a result of, preclinical testing and the clinical trial process that
could delay or prevent our ability to receive regulatory approval or commercialize our product candidates, including:



| |  |  | our preclinical tests or clinical trials may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional
preclinical testing or clinical trials, or we may abandon projects that we expect to be promising;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we might have to suspend or terminate our clinical trials if the participating patients are being exposed to unacceptable health risks;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | regulators may require that we hold, suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements or safety
concerns;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the time or cost of our clinical trials may be greater than we currently anticipate;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | any regulatory approval we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the product not commercially viable;
and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our product candidates may produce undesirable side effects or may have other unexpected characteristics.
| | - |  | ---------------------------------------------------------------------------------------------------------

If we are required to conduct additional clinical trials or other testing of our product candidates beyond those that we currently contemplate, if we are
unable to successfully complete our clinical trials or other testing or if the results of these trials or tests are not positive or are only modestly positive, we may:



| |  |  | be delayed in obtaining marketing approval for our product candidates;
| | - |  | ----------------------------------------------------------------------



| |  |  | not be able to obtain marketing approval; or
| | - |  | --------------------------------------------



| |  |  | obtain approval for indications that are not as broad as intended.
| | - |  | ------------------------------------------------------------------

Our product development costs will also increase if we experience delays in testing or approvals. We do not know whether planned clinical trials will begin as planned, will need to be restructured or will be completed
on schedule, if at all. Significant clinical trial delays also could allow our competitors to bring products to market before we do and impair our ability to commercialize our products or product candidates.

Rapid changes in the pharmaceutical industry may render our products obsolete.

The pharmaceutical industry is characterized by rapid changes in technology, constant enhancement of industrial know-how and frequent emergence of new
products. Future technological improvements and continual product developments in the pharmaceutical market may render our existing products obsolete or affect our viability and competitiveness. Therefore, our future success will largely depend on
our ability to:



| |  |  | improve our existing products;
| | - |  | ------------------------------



18



---

| |  |  | diversify our product portfolio; and
| | - |  | ------------------------------------



| |  |  | develop new and competitively priced products which meet the requirements of the constantly changing market.
| | - |  | ------------------------------------------------------------------------------------------------------------

If we fail to respond to this environment by improving our existing products or developing new products in a timely fashion, or if our new or improved
products do not achieve adequate market acceptance, our business and profitability may be materially and adversely affected.

Anti-corruption
measures taken by the government to correct corruptive practices in the pharmaceutical industry could adversely affect our sales and reputation.

The government has recently taken anti-corruption measures to correct corrupt practices. In the pharmaceutical industry, such practices include, among others, acceptance of kickbacks, bribery or other illegal gains or
benefits by the hospitals and medical practitioners from pharmaceutical distributors in connection with the prescription of a certain drug. Substantially all of our sales to our ultimate customers are conducted through third-party distributors. We
have no control over our third-party distributors, who may engage in corrupt practices to promote our products. While we maintain strict anti-corruption policies applicable to our internal sales force and third-party distributors, these policies may
not be effective. If Liaoning Sunshine Pharmaceutical Company Limited, or Liaoning Sunshine, or any of our third-party distributors engage in such practices and the government takes enforcement action, our products may be seized and our own
practices, and involvement in the distributors practices, investigated. If this occurs, our sales and reputation may be materially and adversely affected.

In addition, government-sponsored anti-corruption campaigns from time to time could have a chilling effect on our efforts to reach new hospital customers. Our sales representatives primarily rely on hospital visits to
better educate physicians on our products and promote our brand awareness. Recently, there have been occasions on which our sales representatives were denied access to hospitals in order to avoid the perception of corruption. If this attitude
becomes widespread among our potential customers, our ability to promote our products will be adversely affected.

We are subject to environmental
regulations and may be exposed to liability and potential costs for environmental compliance.

We are subject to PRC laws and
regulations concerning the discharge of effluent water and solid waste during our manufacturing processes. We are required to obtain clearances and authorizations from government authorities for the treatment and disposal of such discharge. We may
not at all times comply fully with environmental regulations. Any violation of these regulations may result in substantial fines, criminal sanctions, revocations of operating permits, shutdown of our facilities and obligation to take corrective
measures. Our cost of complying with current and future environmental protection laws and regulations and our liabilities which may potentially arise from the discharge of effluent water and solid waste may materially and adversely affect our
business, financial condition and results of operations.

The government may take steps toward the adoption of more stringent environmental
regulations. Due to the possibility of unanticipated regulatory or other developments, the amount and timing of future environmental expenditures may vary substantially from those currently anticipated. If there is any unanticipated change in the
environmental regulations, we may need to incur substantial capital expenditures to install, replace, upgrade or supplement our pollution control equipment or make operational changes to limit any adverse impact or potential adverse impact on the
environment in order to comply with new environmental protection laws and regulations. If such costs become prohibitively expensive, we may be forced to cease certain of our business operations.



19



---

We may be required to defend lawsuits or pay damages for product liability claims. We do not have any liability or
business disruption insurance, and a claim against us, or an interruption in our business, could adversely affect our reputation and our financial results.

The development and commercialization of pharmaceutical products entails an inherent risk of harm to the patient and, therefore, product liability. Even though there are no punitive damages under PRC law, if a product
liability claim is brought against us, it may, regardless of merit or eventual outcome, result in damage to our reputation, breach of contract with our customers, decreased demand for our products, costly litigation, product recalls, loss of revenue
and the inability to commercialize some products. We currently are not aware of any existing or anticipated product liability claims with respect to our products.

Existing PRC laws and regulations do not require us to nor do we maintain liability insurance to cover product liability claims. The insurance industry in China is still at an early stage of development. Insurance
companies in China offer limited business insurance products. As a result, we do not have business liability, or in particular, product liability or disruption insurance coverage for our operations. Any business disruption, litigation or natural
disaster might result in substantial costs and diversion of resources. When and if we attempt to obtain product liability insurance for clinical trials, this insurance may be prohibitively expensive, or may not fully cover our potential liabilities.
The ability to obtain sufficient insurance coverage at an acceptable cost or otherwise to protect against potential product liability claims could prevent or inhibit the commercialization of products that we or our collaborators develop.

The pricing of all of our products is subject to government approval. Changes in government control on prices of our products may limit our profitability or
cause us to stop manufacturing certain products.

Pursuant to the implementing rules of the Drug Administration Law, we are required
to seek pricing approval for all our products from the NDRC and the price administration bureaus of the relevant provinces of the PRC in which our pharmaceutical products are manufactured. We have in the past been able to successfully obtain
pricing-related approvals. In addition, in order to access certain local or provincial-level markets, we enter into government-sponsored competitive bidding processes for EPIAO and our legacy products every year or every other year with a
pre-defined price range. In addition, recent NDRC policies required that we lower prices on our higher dosage EPIAO, which we had previously sold at a premium. The competitive bidding in effect sets price ceilings for our products, thereby limiting
our profitability. In some instances, if the price range designated by the provincial government falls below production costs, we may stop manufacturing certain products.

Chinas accession to the World Trade Organization, or WTO, may intensify competition in the pharmaceutical industry in China.

China acceded to the WTO in December 2001. Following the accession, China lowered tariffs on certain imported pharmaceutical products as part of its
obligation under the WTO framework. The reduction or removal of tariffs on imported pharmaceutical products had made such products more competitive with domestic pharmaceutical products. In addition, an increasing number of foreign-invested
pharmaceutical manufacturers may establish operations to engage in the manufacture or distribution of pharmaceutical products in China, which would increase the number of suppliers of pharmaceutical products in the market and intensify the
competition with domestic manufacturers. If the domestic pharmaceutical manufacturers are unable to distinguish their products from imported products or products produced domestically by foreign-invested pharmaceutical manufacturers which may be of
higher quality and sold at competitive prices, they may lose market share to imported products or products produced domestically by foreign-invested pharmaceutical manufacturers. Furthermore, due to the lack of capital for the research and
development of new medicines, most of the domestic pharmaceuticals are imitations of foreign products. Following Chinas accession to the WTO, many more companies in Europe and the United States have applied for patents in the PRC, thereby
increasing the likelihood of litigation for Chinese domestic pharmaceutical companies.

Risks Related To Doing Business In China

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

All of our operations are located in China, and substantially all of
our sales are 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 extent of government involvement;
| | - |  | -------------------------------------



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



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



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



| |  |  | the allocation of resources;
| | - |  | ----------------------------



| |  |  | an evolving regulatory system; and
| | - |  | ----------------------------------



| |  |  | lack of sufficient transparency in the regulatory process.
| | - |  | ----------------------------------------------------------

While the Chinese economy has experienced significant growth in the past 20 years, growth has been uneven, both geographically and among various sectors of the economy. The Chinese government has implemented various
measures to encourage economic growth and guide the allocation of resources. Some of these measures, including potential investments in competing biopharmaceutical companies, may benefit the overall Chinese economy, but may also have an adverse
effect on us. 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. Further, any adverse change in the economic conditions
or government policies in China could have a material adverse effect on overall economic growth and the level of healthcare investments and expenditures in China, which in turn could lead to a reduction in demand for our products and consequently
have a material adverse effect on our businesses.

The Chinese economy has been transitioning from a planned economy to a more
market-oriented economy. Although in recent years the Chinese 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 Chinese government. The continued control of these assets and other aspects of the national economy by the Chinese government
could materially and adversely affect our business. The Chinese government also exercises significant control over Chinese 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. One recent example is certain measures implemented by the Chinese government in 2006 to restrict foreign investment and speculation in the real estate
sector. Although the government policies have in recent years been encouraging of the growth of the healthcare sector, future attempts by the Chinese government to slow the pace of growth of the healthcare sector or the overall Chinese economy could
result in decreased capital expenditure by hospitals, which in turn could reduce demand for our products.

Moreover, the political
relationship between the United States, Europe, or other Asian nations and China is subject to sudden fluctuation and periodic tension. Changes in political conditions in China and changes in the state of foreign relations are difficult to predict
and could adversely affect our operations. This could lead to a decline in our profitability.



21



---

Future changes in laws, regulations or enforcement policies in China could adversely affect our business.

Laws, regulations or enforcement policies in China, including those regulating healthcare and the pharmaceutical industry, are evolving and
subject to frequent changes. Further, regulatory agencies in China may periodically, and sometimes abruptly, change their enforcement practices. Therefore, prior enforcement activity, or lack of enforcement activity, is not necessarily predictive of
future actions. Any enforcement actions against us could have a material adverse effect on us and the market price of our ADSs. In addition, any litigation or governmental investigation or enforcement proceedings in China may be protracted and may
result in substantial cost and diversion of resources and management attention, negative publicity, damage to our reputation and decline in the price of our ADSs.

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

We receive all
of our revenues in Renminbi, which currently is not a freely convertible currency. A portion of our revenues may be converted into other currencies to meet our foreign currency obligations, including, among others, payment of dividends declared, if
any, in respect of our ordinary shares. Under Chinas existing foreign exchange regulations, we are able to pay dividends in foreign currencies without prior approval from the State Administration of Foreign Exchange, or the SAFE, by complying
with certain procedural requirements. However, the PRC government may take measures to restrict access to foreign currencies for current account transactions.

Our ability to obtain foreign exchange is subject to significant foreign exchange controls and, in the case of amounts under the capital account, requires the approval of and/or registration with PRC government
authorities, including the SAFE. In particular, if Shenyang Sunshine, our wholly-owned PRC subsidiary, takes out foreign currency loans from foreign lenders, it must do so within approved limits that satisfy its approval documentation and PRC debt
to equity ratio requirements. Further, such loans must be registered with the SAFE. These limitations could affect the ability of Shenyang Sunshine to obtain capital through offshore debt or equity financing.

Our revenues are denominated in Renminbi, which may be subject to exchange rate volatility.

Prior to 1994, the Renminbi experienced a significant net devaluation against most major currencies, and there was significant volatility in the
market-based exchange rate during certain periods. From 1994 until July 2005, the Renminbi to U.S. dollar exchange rate was largely stable. On July 21, 2005, the Peoples Bank of China, or PBOC, announced that the exchange rate of U.S.
dollar to Renminbi would be adjusted from US$1.00 to RMB8.27 to US$1.00 to RMB8.11, and it ceased to peg the Renminbi to the U.S. dollar. Instead, the Renminbi has been pegged since that date to a basket of currencies, which components are adjusted
based on changes in market demand and supply under a set of systematic principles. On September 23, 2005, the Chinese government widened the daily trading band for Renminbi against non-US dollar currencies from 1.5% to 3.0% to improve the
flexibility of the new foreign exchange system. On May 18, 2007, the Chinese government further widened the daily trading band from 3.0% to 5.0%. The Renminbi may be revalued further against the U.S. dollar or other currencies, or may be
permitted to enter into a full or limited free float, which may result in an appreciation or depreciation in the value of the Renminbi against the U.S. dollar or other currencies, any of which could give rise to uncertainties in our financial
condition and results of operations. Renminbi appreciated for approximately 13.5% against U.S. dollar from January 2, 2007 to June 20, 2008. Any further appreciation of Renminbi may subject us to increased competition from imports, and any
devaluation of Renminbi may adversely affect the value of our net assets, earnings and declared dividends in foreign currency terms, as well as our ability to import raw materials and equipment and service our foreign currency obligations. For
example, to the extent that we need to convert our U.S. dollars holdings, including the net proceeds 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 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, purchasing equipment and raw materials
from overseas, or 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.

We face risks related to health epidemics and outbreaks of contagious diseases, including avian influenza and
Severe Acute Respiratory Syndrome, or SARS.

Our business could be adversely affected by the effects of avian influenza, SARS or
other epidemics or outbreaks of contagious diseases. There have been recent reports of outbreaks of a highly pathogenic avian influenza, or avian flu, caused by the H5N1 virus in certain regions of Asia and Europe. In recent years, there have been
reports on the occurrences of avian flu in various parts of China, including some confirmed human cases. A major outbreak of avian flu in the human population could result in a widespread health crisis that could adversely affect the economies and
financial markets of many countries, particularly in Asia. Additionally, a recurrence of SARS, a highly contagious form of atypical pneumonia, similar to the occurrence in 2003 which affected China, Hong Kong, Taiwan, Singapore, Vietnam and certain
other countries, would also have similar adverse effects. Since all of our operations and substantially all of our customers and suppliers are based in Asia, an outbreak of avian flu, SARS or other contagious diseases in China, other places in Asia
or elsewhere, or the perception that such outbreak could occur, and the measures taken by the governments of countries affected, would adversely affect our business, financial condition or results of operations. We have not adopted any written
preventive measures or contingency plans to combat any future outbreaks of avian flu, SARS or any other epidemics.

Our operations are subject to the
uncertainty associated with the legal system in China which could limit the legal protection available to potential investors.

We
conduct our business through our operating subsidiaries in China, which are governed by PRC law. China is a civil law jurisdiction based on written codes and statutes. Unlike common law jurisdictions, prior court decisions may be cited as persuasive
authority but do not have legally binding force. The PRC government has promulgated laws and regulations in relation to economic matters in general, such as foreign investment, corporate organization and governance, commerce, taxation and trade,
with a view to establishing a comprehensive legal system conducive to investment activities. However, the implementation, interpretation and enforcement of these laws and regulations may involve greater uncertainty compared to those in the common
law jurisdictions due to a relatively short legislative history, limited volume of court cases and their non-binding nature. Furthermore, many laws, regulations and legal requirements have only recently been adopted by the central or local
government agencies, and their implementation, interpretation and enforcement may involve uncertainty due to the lack of established practice available for reference. Depending on the government agency or how an application or a case is presented to
such agency, we may receive less favorable interpretations of law than our competitors. In addition, any litigation in China may be protracted and result in substantial legal costs and diversion of resources and management attention. Similarly,
legal uncertainty in China may limit the legal protection available to our shareholders. We cannot predict the effect of future legal developments in China, including promulgation of new laws, changes to existing laws or the interpretation or
enforcement thereof, or the preemption of local regulations by national law. As a result, there is substantial uncertainty as to the legal protection available to our shareholders.

There may be difficulties in seeking recognition and enforcement of foreign judgments in China.

Substantially all of our assets are located in China, and most of our senior management members and directors reside in China. However, China has not entered into treaties or arrangements providing for the recognition and enforcement of
judgments made by the courts of the United States or most other jurisdictions. As a result, it may be difficult or impossible for investors to effect service of process or enforce court judgments against our PRC subsidiaries, our assets, senior
management members or directors in China.

Changes in PRC government policy on foreign investment in China may adversely affect our business and
results of operations.

As a foreign invested enterprise, Shenyang Sunshine is subject to restrictions on foreign investment imposed
by PRC law from time to time. For instance, under the Foreign Investment Industrial Guidance Catalogue, some industries are categorized as sectors which are encouraged, restricted or prohibited for foreign investment.



23



---

According to the latest version of this Catalogue, which became effective on January 1, 2005, our
business does not belong to the prohibited or the restricted category. As this Catalogue is updated every few years, there can be no assurance that the PRC government will not change its policies in a manner that would cause part or all of our
businesses to fall within the restricted or prohibited categories. If any of our businesses becomes prohibited or if we cannot obtain approval from relevant approval authorities to engage in businesses which become restricted for foreign investors,
we may be forced to sell or restructure our businesses which have become restricted or prohibited for foreign investment. If we are forced to adjust our corporate structure or business line as a result of changes in government policy on foreign
investment, our business, financial condition and results of operations may be materially and adversely affected.

We rely principally on dividends
and other distributions on equity paid by our wholly owned subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our subsidiaries and affiliated entities to make payments to us could have a
material adverse effect on our ability to conduct our business.

We are a holding company, and we rely principally on dividends from
our wholly owned subsidiaries in China for our working capital requirements, including any debt we may incur. Current PRC regulations permit our subsidiaries to pay dividends to us only out of their accumulated profits, if any, determined in
accordance with Chinese accounting standards and regulations. In addition, each of our subsidiaries in China is required to set aside at least 10% of its after-tax profits each year, if any, to fund a statutory reserve until such reserve reaches 50%
of its registered capital, and each of our subsidiaries may be required to further set aside a portion of its after-tax profits to fund the employee welfare fund at the discretion of the board. These reserves are not distributable as cash dividends.
Furthermore, if our subsidiaries in China incur additional debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other payments to us. In addition, the PRC tax authorities may
require us to adjust our taxable income under the contractual arrangements we currently have in place in a manner that would materially and adversely affect our subsidiaries ability to pay dividends and other distributions to us. Any
limitation on the ability of our subsidiaries and affiliated entities to distribute dividends or other payments to us could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our
businesses, pay dividends, or otherwise fund and conduct our business.

Risks Related To Our Corporate Structure

Our contractual arrangements with Beijing Sunshine Bio-product Sales Company, or Beijing Sunshine, and Liaoning Sunshine and their respective shareholders may not
be as effective in providing control over these entities as direct ownership.

Each of Beijing Sunshine and Liaoning Sunshine was
established in 2000 to engage in the distribution of pharmaceutical products, primarily those which we manufacture. As part of our corporate reorganization prior to our initial public offering in February 2007, we transferred our equity ownership in
Liaoning Sunshine to Mr. Dan Lou, our chairman, and our equity ownership in Beijing Sunshine to Ms. Dongmei Su, our chief technology officer, as a result of which we no longer have equity ownership interests in Beijing Sunshine or Liaoning
Sunshine.

We rely on contractual arrangements to maintain control over the business and operations of these two entities. These
contractual arrangements may not be as effective in providing control over these entities as direct ownership. For example, either Beijing Sunshine or Liaoning Sunshine could fail to take actions required for our business despite their respective
contractual obligation to do so. Substantially all of our sales, including sales of our own and our in-licensed products, are conducted through Liaoning Sunshine, which was the direct contracting party with most of our key distributors. If Liaoning
Sunshine or its sole shareholder, Mr. Dan Lou, refuses to make payments or otherwise refuses to perform their contractual obligations necessary for us to realize these sales contracts, our financial condition and results of operations will be
materially and adversely affected. Beginning in January 2007, we started directly contracting with third-party distributors for the sale of the products we manufacture.



24



---

If Beijing Sunshine, Liaoning Sunshine or their respective shareholders fail to perform under their
agreements with us, we may have to rely on legal remedies under PRC law, which may not be effective. In addition, we cannot assure you that the shareholders of either Beijing Sunshine or Liaoning Sunshine will always act in our best interests.

We currently conduct certain of our sales activities through Liaoning Sunshine and Beijing Sunshine by means of contractual arrangements. If the PRC
government determines that these contractual arrangements do not comply with applicable regulations, our business could be adversely affected.

We conduct certain of our sales activities through contractual arrangements with Liaoning Sunshine and Beijing Sunshine, each of which holds the licenses and approvals, including pharmaceutical trading permits, as
described in Item. 4 Information on the CompanyB. Business OverviewRegulationsDistribution of pharmaceutical products, that are essential for the distribution of our own and in-licensed products. We have contractual
arrangements with Liaoning Sunshine, Beijing Sunshine and their respective shareholders that allow us to substantially control these entities. These contracts include business cooperation agreements, which impose certain restrictions on the conduct
of the Liaoning Sunshines and Beijing Sunshines businesses. For more details, see Item 4. Information on the CompanyA. History and Development of the CompanyOur Contractual Arrangements with Liaoning Sunshine and
Beijing Sunshine. We cannot assure you that we will be able to enforce these contracts.

Although we believe we comply with current
PRC regulations, we cannot assure you that the PRC government would agree that our arrangements with Liaoning Sunshine and Beijing Sunshine comply with PRC licensing, registration or other regulatory requirements, with existing policies or with
requirements or policies that may be adopted in the future. If the PRC government determines that we are not in compliance with applicable law, it could revoke our business and operating licenses, require us to discontinue or restrict our
operations, restrict our right to collect revenues, require us to restructure our operations, impose additional conditions or requirements with which we may not be able to comply, impose restrictions on our business operations or take other
regulatory or enforcement actions against us that could be harmful to our business.

The principal shareholder of Liaoning Sunshine has potential
conflicts of interest with us, which may adversely affect our business.

Liaoning Sunshine is wholly owned by Mr. Dan Lou, our
chairman. While Mr. Dan Lou has a duty of loyalty and care to us under Cayman Islands law, the potential exists for conflicts of interests between his duties to us and his ownership interests in Liaoning Sunshine. In particular, Mr. Lou
may be able to cause our agreements with Liaoning Sunshine to be performed or amended in a manner adverse to us by, among other things, failing to remit payments to us on a timely basis or operating Liaoning Sunshine so as to cause harm to our
business. We cannot assure you that if potential conflicts of interests arise, these conflicts will not result in a significant loss in corporate opportunities for us or a diversion of our resources to Liaoning Sunshine, which may not be in the best
interest of our company and our other shareholders.

Liaoning Sunshine and Beijing Sunshine were previously engaged in activities without the
necessary approvals. This could subject them to fines and other penalties, which could have a material adverse effect on our business.

Liaoning Sunshine and Beijing Sunshine were historically engaged in business activities without requisite approvals. For example, in order to distribute pharmaceuticals as a subsidiary or investee of a foreign invested enterprise, Liaoning
Sunshine and Beijing Sunshine were required to obtain approval from the Ministry of Foreign Trade and Economic Co-operation, or the MOFTEC, which was the predecessor of the Ministry of Commerce, or the MOFCOM. While Liaoning Sunshine and Beijing
Sunshine had the proper permits from the SFDA, neither of them obtained this MOFTEC approval. In connection with our reorganization prior to our initial public offering in February 2007, we have disposed of our respective equity ownerships in
Liaoning



25



---

Sunshine and Beijing Sunshine. Beijing Sunshine and Liaoning Sunshine are no longer required to obtain the approval from the MOFCOM, as each of them is a
domestic Chinese company that is currently operating within its authorized scope of business. However, the relevant PRC authorities have the authority to impose penalties for their past violations. These authorities may revoke business licenses or
the permits granted by the SFDA. Due to the discretionary nature of regulatory enforcements in the PRC, we cannot assure you that Liaoning Sunshine or Beijing Sunshine will not be subject to such type of penalties for its past violations, or that
such type of penalties will not have a material adverse effect on our business.

We must receive the approval of the MOFCOM before we may purchase
the equity interests in Liaoning Sunshine or Beijing Sunshine. We may not receive approval from the MOFCOM for such purchase on a timely basis, or at all.

We are party to two purchase agreements, pursuant to which we may acquire 100% of the equity interests in Liaoning Sunshine from Dan Lou, our Chairman, and 100% of the equity interest in Beijing Sunshine from Dongmei
Su, our chief technology officer, and Shenyang Keweier Advanced Technology Co., Ltd., or Shenyang Keweier, a company owned by our employees and former employees. For more details, see Item 4. Information on the CompanyA. History and
Development of the CompanyOur contractual arrangements with Liaoning Sunshine and Beijing SunshinePurchase agreements for the acquisition of equity interest in Liaoning Sunshine and Beijing Sunshine. In order to complete the
acquisition of Liaoning Sunshine or Beijing Sunshine, we must obtain the approval of the MOFCOM. While we anticipate filing for approval of the acquisition in the near future, we expect that we will not obtain the approval of the MOFCOM for several
months, if at all.

Risks Related To Our ADSs

The market price for our ADSs may be volatile.

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



| |  |  | actual or anticipated fluctuations in our quarterly operating results and changes or revisions of our expected results;
| | - |  | -----------------------------------------------------------------------------------------------------------------------



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



| |  |  | announcements of studies and reports relating to the effectiveness or safety of our products or those of our competitors;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



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



| |  |  | any litigation, governmental investigation or enforcement proceedings brought against us by authorities and industry regulators in China or elsewhere;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | announcements regarding patent litigation or the issuance of patents to us or our competitors;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | addition or departure of our senior management and key research and development personnel;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | changes in the economic performance or market valuations of other pharmaceutical or health care companies;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | economic, regulatory or political developments in China;
| | - |  | --------------------------------------------------------



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



| |  |  | sales of additional ordinary shares or ADSs, or the perception that such sales might occur.
| | - |  | -------------------------------------------------------------------------------------------

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

Dan Lou, our chairman, and his son, Dr. Jing Lou, our chief executive officer, control a number of shares
sufficient to influence corporate actions.

Dan Lou, the chairman of our board of directors, and his son, Dr. Jing Lou, our
chief executive officer, together owned or controlled approximately 10.71% of our outstanding ordinary shares as of April 30, 2008. The interests of the Lou family may differ from those of our other shareholders, and they may take actions that
advance their interests to the detriment of our other shareholders. Acting together, they would have sufficient voting power to influence the outcome of corporate actions submitted to the shareholders for approval and to influence our management and
affairs, including the election of our board of directors. Chairman Lou is not required to stand for election at any meeting of our shareholders, and therefore serves for an undetermined period of time. In addition, this concentration of ownership
may prevent attempts to remove or replace senior management.

Our articles of association contain anti-takeover provisions that could adversely
affect the rights of holders of our ordinary shares and ADSs.

Our amended and restated memorandum and articles of association
include provisions that could 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 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. These provisions could also serve to entrench our existing board of directors and
management. For example, our board of directors has the authority, without further action by our shareholders, to issue preferred shares in one or more series and to fix their designations, powers, preferences, privileges, and relative
participating, optional or special rights and the qualifications, limitations or restrictions, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the
rights associated with our ordinary shares, in the form of ADS or otherwise. Preferred shares 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 issues preferred shares, the market price of our ordinary shares or ADSs may decline and the voting and other rights of the holders of our ordinary shares and ADSs may be adversely affected. In addition, our articles of
association provide that only a third of our board must stand for re-election at any annual meeting.

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

Holders of ADSs do not have the same rights as holders
of our ordinary shares and ADS holders only have such rights as are specified in the deposit agreement, which generally are more restricted than the rights of holders of ordinary shares. Under the deposit agreement, if the vote is by show of hands,
the depositary will vote the deposited securities in accordance with the voting instructions received from a majority of holders of ADSs that provided timely voting instructions. If the vote is by poll, the depositary will vote the deposited
securities in accordance with the voting instructions it timely receives from ADS holders. In the event of poll voting, deposited securities for which no instructions are received will not be voted. Under our articles of association, the minimum
notice period required to convene a general meeting is seven 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 shares. 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 ordinary shares are not voted as you requested. In addition, in your capacity as an ADS holder, you will not be able to call a shareholder meeting.



27



---

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 of 1933, as amended, or the Securities Act, or an
exemption from the registration requirements is available. Also, under the deposit agreement, the depositary 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 endeavor to cause such a registration
statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your
holdings.

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 inequitable or impractical to make a distribution available to any holders of ADSs. For example, the depositary may determine that it is not practicable to distribute certain property through the mail, or that the value
of certain distributions may be less than the cost of mailing them. In these cases, the depositary may decide not to distribute such property, in which event you would 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 under United
States law, you may have less protection of your shareholder rights than you would under United States law.

Our corporate affairs
are governed by our amended and restated memorandum and articles of association, the Cayman Islands Companies Law and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, the rights of minority
shareholders to institute actions, 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, the latter of 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 states in the United States, such as Delaware, have more developed and judicially interpreted bodies of corporate law than the Cayman Islands.

There is uncertainty regarding whether Cayman Islands courts would:



| |  |  | recognize or enforce against us or our directors or officers judgments of courts of the United States predicated upon certain civil liability provisions of United
States securities laws; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



28



---

| |  |  | impose liability against us, in original actions brought in the Cayman Islands, based on certain civil liability provisions of United States securities laws or laws
of any state in the United States
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As a result of all of the above, our public shareholders may have more difficulty in
protecting their interests in the face of actions taken by our management, directors or major shareholders than they would as public shareholders of a United States company.

Your ability to bring an action against us or against our directors and officers, or to enforce a judgment against us or them, will be limited because we are incorporated in the Cayman Islands, because we
conduct substantially all of our operations in China and because the majority of our directors and officers reside outside of the United States.

We are incorporated in the Cayman Islands, and we conduct substantially all of our operations in China through our PRC subsidiaries. Most of our directors and officers reside, and substantially all of the assets of
those persons are located, outside the United States. As a result, it may be difficult or impossible for you to bring an action in the United States against us or against these individuals in the event that you believe that your rights have been
violated under United States securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands or China may render you unable to enforce a judgment against our assets or the assets of our
directors and officers.

A. History and Development of the
Company

Our Contractual Arrangements with Liaoning Sunshine and Beijing Sunshine

Historically, we conducted our manufacturing and marketing activities through our wholly owned subsidiary, Shenyang Sunshine, and our distribution and
logistics activities through Beijing Sunshine and Liaoning Sunshine. Prior to our reorganization in anticipation of our initial public offering in February 2007, Beijing Sunshine and Liaoning Sunshine, as investees of a foreign invested enterprise,
engaged in distribution of pharmaceutical products without the requisite approvals from the MOFCOM. For more details, see Item 3. Key InformationD. Risk Factors Risk factorsRisks related to our corporate structureLiaoning
Sunshine and Beijing Sunshine were previously engaged in activities without the necessary approvals. This could subject them to fines and other penalties, which could have a material adverse effect on our business. As part of our corporate
reorganization, Shenyang Sunshine sold 45% of the equity interest in Beijing Sunshine to Ms. Dongmei Su, our chief technology officer, in October 2006, and 90% of the equity interest in Liaoning Sunshine to Mr. Dan Lou, our chairman, in
November 2006. Beijing Sunshine and Liaoning Sunshine are no longer required to obtain the approval from the MOFCOM, as each of them is a domestic Chinese company that is currently operating within its authorized scope of business. In December 2006
and January 2007, Shenyang Sunshine entered into the following contractual arrangements with Beijing Sunshine and Liaoning Sunshine, respectively, to enable us to maintain control in these two entities. Under these contractual arrangements, Shenyang
Sunshine bears economic



29



---

risks with respect to, and derives economic benefits from, the operations of Beijing Sunshine and Liaoning Sunshine through its entitlement to a majority of
their revenues in the form of technology support, market development and consulting service fees.

Business cooperation agreements

Pursuant to the business cooperation agreement among Shenyang Sunshine, Liaoning Sunshine and us, Shenyang Sunshine provides
technology support services and market development and consulting services to Liaoning Sunshine, and, as consideration, receives 70% of Liaoning Sunshines annual sales revenues as service fees. In addition, Liaoning Sunshine has agreed that,
without the prior written consent of a majority of our independent directors, it will not increase or decrease its registered capital, declare dividends or make similar payments, make any investment, incur any indebtedness, mortgage or dispose of
its material assets, or consolidate or merge with any other entity. Liaoning Sunshine has further agreed to distribute only those products that are produced by Shenyang Sunshine, except as otherwise agreed to by a majority of our independent
directors. Shenyang Sunshine will be entitled to any intellectual property developed during the term of this contract. Similarly, Beijing Sunshine, Shenyang Sunshine and us entered into a business cooperation agreement on the same terms.

Purchase agreements for the acquisition of equity interests in Liaoning Sunshine and Beijing Sunshine

Pursuant to the purchase agreement between Shenyang Sunshine and Mr. Dan Lou, Mr. Dan Lou granted Shenyang Sunshine an exclusive right to
purchase, to the extent permissible under PRC law, his 100% equity interest in Liaoning Sunshine for a purchase price of RMB15.0 million, an amount equivalent to the registered capital of Liaoning Sunshine, immediately after Shenyang Sunshine
obtains the requisite PRC government approval for it to acquire Liaoning Sunshine.

RMB13.5 million of the purchase price pursuant to the
purchase agreement was prepaid by Shenyang Sunshine to Mr. Lou shortly after the signing of this agreement in December 2006. The remaining RMB1.5 million will be paid to Mr. Lou at closing. If Shenyang Sunshine fails to obtain the
requisite government approval for Shenyang Sunshine to complete the acquisition within ten years, Shenyang Sunshine shall have the right to terminate the agreement and Mr. Dan Lou shall return the prepayment of RMB13.5 million to Shenyang
Sunshine.

Similarly, Beijing Sunshine, Shenyang Keweier and Shenyang Sunshine entered into a purchase agreement on the same terms, except
that each of Beijing Sunshine and Shenyang Keweier granted Shenyang Sunshine an exclusive right to purchase their respective equity interests in Beijing Sunshine for a purchase price equivalent to their proportionate registered capital in Beijing
Sunshine.

Voting agreements

Pursuant to the voting agreement among Shenyang Sunshine, Mr. Dan Lou and Liaoning Sunshine, Mr. Dan Lou is required to consult with and follow any lawful instruction of Shenyang Sunshine whenever he exercises his rights as
Liaoning Sunshines shareholder.

Pursuant to the voting agreement among Shenyang Sunshine, Ms. Dongmei Su, Shenyang Keweier and
Beijing Sunshine, Ms. Dongmei Su and Shenyang Keweier are required to consult with and follow any lawful instruction of Shenyang Sunshine whenever they exercise their rights as Beijing Sunshines shareholders.

Equity pledge agreements

Pursuant to the
equity pledge agreement between Shenyang Sunshine and Mr. Dan Lou, Mr. Dan Lou pledged all of his equity interests in Liaoning Sunshine to Shenyang Sunshine to guarantee his obligations under



30



---

the purchase agreement and the voting agreement. If Mr. Dan Lou breaches his contractual obligations, Shenyang Sunshine, as pledgee, will be entitled to
certain rights, including the right to purchase the pledged equity interests or sell the same to any third party. Mr. Dan Lou has agreed not to dispose of the pledged equity interests or take any actions that would prejudice Shenyang
Sunshines interest.

Ms. Dongmei Su and Shenyang Keweier entered into a similar agreement with Shenyang Sunshine to pledge their
respective equity interests in Beijing Sunshine to Shenyang Sunshine.

Prior to the execution of the above agreements, Shenyang Sunshine
held 90% and 45% equity interests in Liaoning Sunshine and Beijing Sunshine, respectively, with the remaining interests in the two companies held by the former majority shareholder of Shenyang Sunshine, Shenyang Keweier. Both Liaoning Sunshine and
Beijing Sunshine were consolidated by Shenyang Sunshine prior to the execution of the above agreements as a result of its 90% controlling interest in Liaoning Sunshine and as the primary beneficiary of Beijing Sunshine, which was deemed as a
variable interest entity, or VIE, in accordance with Financial Accounting Standards Board (FASB) Interpretation No. 46 (revised December 2003), Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51, or
FIN 46R, effective from January 1, 2006. Specifically, the total equity investment at risk of Beijing Sunshine was deemed insufficient to fund its activities without additional subordinated financial support from Shenyang Sunshine in the form
of subordinated trade payable arising from the sales of products from Shenyang Sunshine to Beijing Sunshine.

As a result of the above
contractual arrangements, Shenyang Sunshine bears economic risks with respect to, and derives economic benefits from, the operations of Liaoning Sunshine and Beijing Sunshine. As Shenyang Sunshine continues to hold the predominant variable interests
in Liaoning Sunshine and Beijing Sunshine, it is deemed to be the primary beneficiary of both entities under FIN 46R. Accordingly, the transfers of equity interests in Liaoning Sunshine and Beijing Sunshine did not change the requirement to
consolidate the two entities, and the financial statements of Liaoning Sunshine and Beijing Sunshine continue to be included in our consolidated financial statements subsequent to the execution of the above agreements.

EPIAO (

LOGO)

Launched in 1998, EPIAO is an injectable recombinant human erythropoietin, or EPO, that is
used to stimulate the production of red blood cells in patients with anemia and to reduce the need for blood transfusions. Anemia is a condition in which insufficient oxygen is delivered to the bodys organs and tissues. EPIAO is a
protein-based therapeutic comparable in structure and function to Amgen Inc.s Epogen and Kirins ESPO.

According to IMS Health, an independent research firm, revenues from all EPO drug sales in China were
estimated at approximately RMB417 million (US$57.2 million) in 2007, representing an approximately 18% compound annual growth rate, or CAGR, from 2003. EPIAO, as tracked by IMS Health, has been ranked as the number one EPO drug since 2002 in terms
of both units sold and revenues among the foreign and domestic biopharmaceutical companies marketing EPO drugs in China. We have sold over 9.2 million vials of EPIAO since 1999. According to data derived from IMS Health, EPIAO has been the
market leader in China since 2002 both in terms of revenues and sales volume, with market shares of 39.9% and 32.6% respectively in 2007.

EPIAO is approved by the SFDA for three distinct indications: anemia associated with chronic renal failure; red blood cell mobilization, which is the process in which red blood cells are stimulated to proliferate, before, during, and after
surgery; and anemia associated with chemotherapy in cancer patients with non-myeloid malignancies, which are cancers that do not originate in the bone marrow or involve myeloid cells, or non-lymphocyte white blood cells found in the bone marrow. We
were granted exclusivity by the SFDA for the manufacturing and marketing of EPIAO for anemia associated with chemotherapy in cancer patients with non-myeloid malignancies under an administrative protection period through September 2007, during which
other pharmaceutical companies are prohibited from manufacturing or importing similar drugs, except those whose applications for clinical trials were approved by the SFDA prior to the commencement of our administrative protection.

In 2007, we received from the SFDA licenses to produce and sell pre-filled syringe EPIAO in 2,000 IU, 3,000 IU, 4,000 IU and 10,000 IU strengths. The
pre-filled syringe EPIAO will be an important addition to our product portfolio because of its increased safety, ease of use and the flexibility to self-administer the medication at home. We launched our new pre-filled syringe EPIAO format in June
2007. We plan to complete pre-clinical trial in 2008 for NuPIAO, our second-generation EPIAO product candidate. NuPIAO is designed to have a longer half-life relative to our first-generation EPIAO. In addition, we completed the Phase III trial for
high dose (36,000 IU/vial) formulation of EPIAO and will commence patient follow-up visits in the second half of 2008. The data generated from these follow-up visits are not required for SFDA approval and are for our internal reference only. We
expect to apply for SFDA approval in the third quarter of 2008. If approved, we expect the product to be the first of its kind in the Chinese market.

TPIAO (

LOGO)

We launched TPIAO, our newest internally developed protein-based therapeutic product, in
January 2006. This product is a TPO indicated for the treatment of chemotherapy-induced thrombocytopenia, a deficiency of platelets. Platelets are disc-shaped cells in the blood that assist in coagulation and the arrest of bleeding by repairing the
walls of blood vessels. TPIAO represents the first protein-based therapeutic of its type approved for thrombocytopenia in China. We have a monitoring period for TPIAO through 2010, during which other pharmaceutical companies are prohibited from
manufacturing or importing a similar drug, except those whose applications for clinical trials were approved by the relevant Chinese authority prior to May 2005, the commencement of TPIAOs monitoring period. For 2007, our total revenues from
TPIAO sales were RMB43.1 million, accounting for 23.9% of our overall revenues for the year. We are also conducting a late-stage clinical trial of TPIAO for the treatment of idiopathic thrombocytopenic purpura, or ITP, an immune system disorder in
which the body perceives platelets as foreign and destroys them. We have made significant progress and expect to complete the clinical trial and file for SFDA approval in the fourth quarter of 2008.

Our Legacy Products

In addition to EPIAO and TPIAO,
we market two other protein-based therapeutics that had historically been significant contributors to our overall revenues. Due to unfavorable pricing and increased competition, we refocused our sales and marketing efforts in early 2004, and our
legacy products are now marketed primarily by distributors.

Intefen (

LOGO). Intefen is our recombinant interferon alpha-2a product. Intefen is indicated for the treatment of carcinomas of the lymphatic or hematopoietic system, such as lymphoma and leukemia, and viral infectious
diseases, such as hepatitis C. We launched Intefen in the Chinese market in 1995.

Inleusin (

LOGO). Inleusin is our recombinant human interleukin-2, or IL-2, product. Inleusin is indicated for the treatment of renal cell carcinoma, the most common form of kidney cancer, metastatic melanoma, a type of skin
cancer, and thoratic fluid build-up caused by cancer and tuberculosis. Inleusin is designed to stimulate the immune system in order to fight cancer and infectious diseases. We launched Inleusin in the Chinese market in 1996.

Our In-Licensed Products

Tietai Iron Sucrose
Supplement (

LOGO). ietai Iron Sucrose Supplement, an intravenously administered prescription drug that is designed to treat anemia associated with iron deficiency, is indicated for patients with end-stage renal disease requiring
iron replacement therapy. We in-licensed five-year exclusive PRC distribution rights for this product from Shenyang Borui Pharmaceutical Company Limited, or Borui, in May 2006. Tietai Iron Sucrose Supplement was launched in China in 2005 by Borui.
We began to generate revenues from the sale of Tietai Iron Sucrose Supplement in the beginning of 2007. We believe such product will be complementary to our EPIAO product lines as we have a strong brand reputation in the nephrology market in China,
and Tietai Iron Sucrose is designed to treat anemia associated with iron deficiency for patients with renal disease.

In 2008, we entered
into an agreement with Borui to purchase the rights to Tietai Iron Sucrose Supplement. We can provide no assurances as to if or when such transaction will be completed.

Baolijin (

LOGO). In August 2006, we in-licensed exclusive PRC distribution rights for Baolijin, a recombinant human granulocyte colony-stimulating factor, or G-CSF, indicated for the treatment of neutropenia, a condition
associated with chemotherapy and characterized by low levels of neutrophils, a type of white blood cell important for fighting infections, from Chengdu Biological Institute for a period of five years. Due to significantly increased competition and
low pricing structure, we no longer sell the product in China.

Licenses to Tietai Iron Sucrose Supplement and to Baolijin are held by
Liaoning Sunshine, our variable interest entity.

Export Sales

We currently market our products through distribution agreements with local agents in several developing countries, consisting of Egypt, Pakistan, Thailand, Brazil, Mexico, Trinidad and Tobago, Guatemala and Columbia.
Export sales accounted for 4.9%, 4.6% and 3.8% of our total revenues in the years ended December 31, 2005, 2006 and 2007, respectively.

Our
Product Pipeline

We focus our research and development efforts on both novel and validated protein-based therapeutics for the treatment
of diseases in the areas of nephrology, oncology, supportive cancer care, inflammation and infectious diseases. Our product pipeline, which we expect will be a key contributor to our future growth, consists of six product candidates in various
stages of development. We employ a market-driven approach to our research and development efforts, and our team utilizes the latest molecular biology and biochemical techniques and technologies to develop promising product candidates. Our
diversified product pipeline includes a number of next-generation protein-based therapeutics including NuPIAO, our second-generation EPIAO product candidate; NuLeusin, our next-generation Inleusin product candidate; TPIAO for the treatment of ITP; a
human papilloma virus, or HPV, vaccine for the prevention of cervical cancer; and an anti-TNF humanized monoclonal antibody product candidate for the treatment of rheumatoid arthritis and other autoimmune diseases. We believe that each of these
product candidates, if successfully developed and approved, would address significant market opportunities. We are required to conduct extensive preclinical and clinical trials in order to generate safety and efficacy data to support a filing for
approval by the SFDA.

We maintain a sales and marketing force in 30 provinces and major cities in China, including the municipalities of
Beijing and Shanghai and the city of Guangzhou. As of December 31, 2007, our principal products were marketed by our 194 sales and marketing professionals and sold by our network of approximately



33



---

150 distributors to healthcare providers including, based on our internal estimates, approximately 1,600 hospitals, clinics and dialysis centers. Our
internal sales and marketing staff details our principal products to physicians and hospital administrators and, as required by PRC laws, our distributors are engaged to contract with our customers for the sale of our principal products to
physicians and hospitals. In addition, our legacy products Intefen and Inleusin are marketed, as well as sold, by distributors. Our sales force in China benefits from over ten years of experience in marketing protein-based therapeutics. As a result
of our history as a provider of therapeutics to the Chinese market, we believe our Shenyang Sunshine brand is widely recognized throughout the PRC for quality and reliability.

We conduct on-site, bulk manufacturing, finishing and packaging activities for EPIAO, TPIAO, Intefen and Inleusin at our 3,000 square meter Shenyang,
China facility. We also manufacture our products and product candidates for clinical trials at this facility. Our Shenyang facility was re-certified in 2005 in accordance with Chinese current GMP, and such certificate is valid for five years until
2010. We plan to expand our plant in Shenyang to increase our manufacturing capacity, and further take advantage of our favorable cost structure.

Our
Product Portfolio

Our principal products target large markets with significant unmet medical needs in nephrology, oncology, supportive
cancer care, inflammation and infectious disease. We are currently focused on expanding the indication for our marketed products, developing next generation, enhanced versions of our marketed products, and bringing novel protein-based therapeutics
to market.

The table below summarizes our products and product candidates:

Our Principal Products

EPIAO (

LOGO)

EPIAO, our flagship product, is an injectable recombinant human erythropoietin (EPO) that
stimulates the production of red blood cells, cells that transport oxygen from the lungs to all cells of the body. EPO is a naturally occurring growth factor that is normally produced in healthy kidneys and regulates production of red blood cells.
Adequate amounts of EPO are required to produce a sufficient number of red blood cells. A significant reduction in the number of circulating red blood cells results in anemia, a condition in which insufficient oxygen is delivered to the bodys
organs and tissues. For example, patients with chronic renal failure suffer from anemia because they do not produce sufficient amounts of EPO. Anemia can also be a side effect of chemotherapy treatments for patients, sometimes forcing patients to
discontinue chemotherapy.

According to IMS Health, revenues from all EPO drug sales in China were estimated at approximately RMB417
million (US$57.2 million) in 2007, representing a CAGR of approximately 18% from 2003 to 2007.

EPIAO is utilized as a replacement protein
therapy to restore EPO to normal, or physiological levels, stimulate red blood cell production and relieve the symptoms of anemia, thereby improving the quality of life for patients with renal disease and cancer in addition to reducing the need for
continuous blood transfusions. Our EPIAO products are available in four different strengths (2,000 IU/vial, 3,000 IU/vial, 4,000 IU/vial and 10,000 IU/vial) and approved for three distinct medical indications. To date, no other EPO product has been
approved in China for all three indications.



| |  |  | In 1998, we received approval for the first indication, anemia associated with chronic renal failure;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | In 2000, we received approval for the use of EPIAO to mobilize red blood cell in patients before, during and after surgery to facilitate a quicker recovery and
reduce the need for blood transfusion; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In 2001, we received approval for anemia associated with chemotherapy in cancer patients with non-myeloid malignancies. These patients become anemic as a side
effect of chemotherapy and as a general complication associated with cancer. For this indication, on September 6, 2001 we were also granted a six-year exclusivity under an administrative protection period ending in September 2007 during which
other pharmaceutical companies were prohibited from importing or marketing a similar product.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We were among the first
biotechnology companies to introduce a recombinant form of EPO in China. According to IMS Health, our EPIAO was the most widely used recombinant EPO in China in each of the twenty quarters ending with the first quarter of 2007. EPIAO is on the
National Reimbursement List for the treatment of anemia associated with chronic renal failure and for the treatment of anemia associated with chemotherapy in non-myeloid malignancies in certain provinces and cities such as Hubei Province and
Shanghai Municipality. According to data from IMS Health, our EPIAO has been the market leader in China since 2002 both in terms of revenues and sales volume, with market shares of 39.9% and 32.6% respectively in 2007.

In 2006, we received from the SFDA licenses to produce and sell pre-filled syringe EPIAO in 2,000 IU, 3,000 IU, 4,000 IU, 10,000 IU strengths. We
launched these new EPIAO formats in June 2007. The pre-filled syringe EPIAO has been an important addition to our product portfolio because of its increased safety, ease of use and the flexibility to self-administer the medication at home.

We completed the Phase III clinical trial for our high dose (36,000 IU/vial) formulation of our first generation EPIAO in 2007 and expect
to apply for SFDA approval in the third quarter of 2008. We expect the product to be the first of its kind in China. In addition, we expect to complete in 2008 pre-clinical trial for our NuPIAO, our second-generation EPIAO. We have designed this
product candidate to possess a longer half-life versus our first generation EPIAO, and we believe that, in this aspect, it is comparable to Amgens Aranesp. We have already filed a patent application in China for NuPIAO.

We believe our competitive advantages in marketing our EPIAO lie in the following areas:

Focus on quality. We implemented our proprietary process technology and developed quality assurance and control system in compliance with the
Chinese GMP standards. Since 2004, we have applied the European Pharmacopoeia (2002 version) standards, which we believe are higher production quality standards than those required for domestic pharmaceutical manufacturers.

Broadest applications and specifications. Since 2002, our EPIAO products have been the only EPO products approved for each of the following
three indications: anemia associated with chronic renal failure; red blood cell mobilization; and chemotherapy induced anemia in cancer patients. We provide our EPIAO products in four dosage forms to meet the needs of our patients and their doctors.
We expect to apply for marketing approval from the SFDA of an additional high dosage form for use in chemotherapy induced anemia in 2008 which we believe, if approved, will be the highest approved dosage formulation of an EPO drug on the Chinese
market.

Competitive pricing. Our economy of scale, favorable cost structure and experience in manufacturing afford us the
opportunity to competitively price EPIAO while still maintaining attractive margins. In order to secure and maintain a large customer base, we have been pricing our EPIAO products at a level less than one-third of the comparable products produced
overseas.

Strong brand awareness. We believe our sustained marketing efforts with medical practitioners and our focus on
pre-sale and post-sale services have established EPIAO and Shenyang Sunshine as well-recognized and well-received brands. We have been implementing a focused marketing strategy since launching the product in 1998. As part of this strategy, our sales
representatives promote our products to doctors by visiting hospitals to better educate physicians and develop brand awareness. Our sales force has increased to 194 as the end of 2007 from 152 at the end of year 2006 as a result of deployment of our
strategy in creating a dedicated sales team which focuses specifically on the oncology areas to supplement our existing focus in nephrology.

Clinical Trials. In 1997, we completed a multicenter, randomized clinical trial with EPIAO in 194 end-stage renal disease patients. This trial compared the efficacy of our product to that of Epogen, Amgens recombinant EPO.
The data demonstrated that our product was biologically equivalent to Epogen, as demonstrated by comparable restoration of hematocrit and hemoglobin levels, indicators of red blood cell reemergence. Additionally we did not observe any severe adverse
reactions. We obtained approval from a branch of the Ministry of Health, or the MOH, in November 1997 and launched EPIAO in China in August 1998.

In 2001, we completed a multicenter, randomized, double blind, placebo-controlled clinical extension trial to evaluate the efficacy of EPIAO in 121 cancer patients with anemia resulting from their chemotherapy regimens. The primary endpoint
of this clinical trial was restoration of hemoglobin and hematocrit levels. Patients received either EPIAO or a placebo three times a week for 12 weeks. The results demonstrated that EPIAO was effective in restoring hemoglobin and hematocrit levels
in this patient setting. We obtained SFDA approval for this indication in September 2001 and launched EPIAO for this indication in December 2002. When we obtained the SFDA approval in September 2001, we were also granted a six-year administrative
protection period for this indication of EPIAO. During the protection period, other pharmaceutical companies were prohibited from manufacturing EPO drugs for the same indication or adding the same indication on the label of any existing drugs,
pursuant to the Regulations for New Drug Protection and Related Technology Transfer.

In 2000, we completed a multicenter, randomized
placebo controlled extension trial in 105 patients undergoing major orthopedic surgery to evaluate the efficacy of EPIAO in mobilization of red blood cells in patients undergoing surgery. Typically, these patients require allogeneic blood
transfusion, where blood comes from a donor instead of the patient himself, thereby exposing the patients to the risk of contracting blood-borne diseases. The primary endpoint of this clinical trial was also restoration of hemoglobin and hematocrit
levels. Compared with placebo-controlled patients, patients who received EPIAO before, during and after the surgery had higher levels of hemoglobin and hematocrit. We received SFDA approval for this indication in 2000 and launched EPIAO for this
indication in December 2002.

TPIAO (

LOGO)

Launched in January 2006, TPIAO is our recombinant human thrombopoietin product for the treatment
of chemotherapy-induced thrombocytopenia, or platelet deficiency, and represents the first such protein-based therapeutic approved and launched for this indication in China. TPO is a hemopoietic, or blood or blood cell-related, growth factor protein
found in plasma. TPO naturally stimulates production of megakaryoctyes, cells with a mutilobed nucleus in the bone marrow and liver, thereby releasing mature platelets and raising the circulating platelet count without increasing the platelet
function. Patients undergoing blood stem cell transplantation or cancer chemotherapy, or with late-stage liver diseases, or for unknown pathological reasons may suffer from platelet deficiency. We market TPIAO in two strengths: 7,500 IU/vial and
15,000 IU/vial. We began marketing our TPIAO products at the end of 2005 on a trial basis and recorded revenues of RMB2.8 million, RMB16.1 million and RMB43.1 million in the years ended December 31, 2005, 2006 and 2007, respectively.

We began our research and development efforts on TPIAO in 1995 as part of the national 863 scientific program. After
successful discovery and pre-clinical studies, we initiated clinical trials in 1999. Phase I and Phase II clinical trials were completed in 2001 and 2002, respectively, which indicated TPIAOs safety and efficacy.

In 2003, we completed a multicenter, randomized, double-blind placebo self-controlled Phase III trial in 305 patients, 223 of whom were cancer patients
receiving chemotherapy and 82 of whom were ITP patients who had failed to respond to any other form of treatment. Patients were treated with TPIAO within six to 24 hours after the first chemotherapy cycle daily for 14 days. The primary endpoints
were platelet counts and reduction in the number of transfusions. In this trial, TPIAO treatment resulted in a higher platelet count in approximately 78% of the cancer patients and approximately 85% of the ITP patients. There were 18 cases of mild
adverse reactions relating to TPIAO treatment, including transient flu-like symptoms, but patients spontaneously recovered without discontinuing treatment.

Although we obtained SFDA approval for TPIAO in May 2005, the SFDA has required us to conduct a Phase IV post-marketing trial on TPIAO as a supportive cancer care product. We expect that the three-arm trial will
include approximately 1,000 cancer patients being treated with chemotherapy. The primary endpoint will be time to recovery of platelet count to normal levels. We initiated this trial in the fourth quarter of 2006 and plan to release clinical data
for the trial in 2009.

TPIAO was approved in May 2005 with a monitoring period of five years, which will expire in May 2010. During the
monitoring period, other pharmaceutical companies are prohibited from manufacturing or importing a similar drug except those whose application for clinical trial were approved by the SFDA prior to May 2005, the commencement of TPIAOs
monitoring period, pursuant to the PRC Administrative Measures for the Registration of Medicine. Although we believe TPIAO is the only TPO-based therapeutic available in the Chinese market to date, we are aware of another Chinese pharmaceutical
company, CP Guojian, which we believe may be conducting clinical trials for a TPO-based therapeutic in China. If CP Guojian obtained the approval for any clinical trials prior to commencement of the monitoring period for TPIAO, CP Guojian may not be
prohibited from manufacturing and marketing its TPO product during TPIAOs monitoring period. We have no information on when CP Guojian plans to bring their product to market, nor are we aware of any other company that is developing a similar
product. We have two issued patents in relation to TPIAO. We obtained authorization to introduce TPIAO into the Chinese market for treatment of chemotherapy-induced thrombocytopenia in 2005.

Legacy Products

In addition to EPIAO and
TPIAO, we market two protein-based therapeutics that have historically been significant contributors to our overall revenues. Due to unfavorable pricing and increased competition, we refocused our sales and marketing efforts since early 2004 and no
longer heavily market these products with our own sales force.

Intefen (

LOGO). Intefen is our recombinant human interferon alpha-2a product for the treatment of malignancies of the lymphatic or hematopoietic system, and viral infectious diseases, including adult chronic hepatitis B, acute
and chronic hepatitis C, and genital warts. Interferon is a protein that occurs naturally in the body in very small amounts and comes in three main types: alpha, beta and gamma. When exposed to viruses, certain cells produce interferon, which is
released into the bloodstream or intercellular fluid to induce healthy cells to produce enzymes and proteins that counter and combat the infection. The anti-cellular or immuno-regulatory functions of IFN can enable interferon products to play a
central role against certain tumor and auto-immune diseases. Interferon alpha has been manufactured by pharmaceutical companies for therapeutic use against hairy-cell leukemia, hepatitis C and hepatitis B, as well as for treatment of genital warts
and some rare cancers of blood and bone marrow.

We obtained SFDA approval to market Intefen in April 1995 and launched the product in
December 1995. Our Intefen is available in lyophilized powder and injectable solution. Both the powder and solution come in three strengths: 1 MIU (million international unit)/vial, 3 MIU/vial and 5 MIU/vial. Revenues from our Intefen products were
RMB4.1 million (US$0.6 million) in 2007, representing a decrease of 40.0% over 2005.

In 1994, we completed a multicenter, randomized Phase
III clinical trial with Intefen in 127 patients with hepatitis C virus, or HCV. The primary endpoints of the trial were the change in ALT, or Alanine Amino Transferase recovery rates, a measurement of liver function and HCV RNA clearance rates, a
measure of the number of viruses present in the patient. The data indicated that Intefen was comparable to Schering Ploughs Intron A when measured with these two tests. The observed side effects were flu-like symptoms that were relatively
minor and reversed upon discontinuation of the therapy.

Inleusin(

LOGO). Inleusin is our recombinant human interleukin-2, or IL-2, product that is structurally and functionally the same to naturally occurring IL-2, a body immune regulator. Inleusin is indicated for treatment of
renal cell carcinoma, melanoma, thoratic fluid build-up caused by cancer, and tuberculosis. IL-2 is a natural part of the bodys immune response to microbial infection. IL-2 promotes the proliferation and maturation of, among others, T-cells
and natural killer cells, both of which are capable of destroying cancer cells directly. IL-2 plays a role in the development of white blood cells or lymphocytes, and anti-inflammatory reactions which are part of the regulation of the immune
response.

We obtained SFDA approval to market Inleusin in the Chinese market in June 1995 and launched the product in March 1996. It was
the first interleukin product introduced into the Chinese market. Our Inleusin products come in four strengths: 0.1 MIU/vial, 0.2 MIU/vial, 0.5 MIU/vial and 1 MIU/vial. Revenues from our Inleusin products were RMB1.0 million (US$0.1 million) in
2007, representing a decrease of 36.1% over 2005.

In 2002, we completed a multicenter, randomized, placebo-controlled extension study in
209 patients with tuberculosis. The primary endpoint was the reduction of severity of infection as measured by thoracic X-Ray imaging the reduction in the number of tuberculosis bacilli, an infectious organism, in a sputum smear. The data
demonstrated that Inleusin effectively reduced the severity of tuberculosis in these patients.

In-Licensed Products

Tietai Iron Sucrose Supplement (

LOGO). Tietai Iron Sucrose Supplement is a complex of polynuclear iron (III)-hydroxide, a bioavailable form of iron, in a sucrose solution for intravenous use. It is indicated for the treatment of iron deficiency
anemia in patients with end-stage renal disease and generally considered to have a superior safety profile compared to other forms of iron supplements. Tietai Iron Sucrose Supplement was launched in China in 2005 by Borui, the licensor. We began to
generate revenues from the sale of Tietai Iron Sucrose Supplement in the beginning of 2007.

In May 2006, we entered into an agency
agreement with Borui to in-license nationwide exclusive rights in China to market and distribute Tietai Iron Sucrose Supplement from June 1, 2006 to August 31, 2011. Pursuant



38



---

to this agreement, we purchase Tietai Iron Sucrose Supplement from Borui at a fixed price and are subject to certain minimum purchase requirements, sales and
market share targets for every twelve-month period starting from September 2006. As long as we achieve the sales targets during the term of the agreement, we have the right to renew the agreement upon its expiry and obtain the agency right of any
other new product developed by Borui. Our rights under the agreement will be subject to Boruis ability to renew both its business license, which currently expires in 2008, and its license from Chengdu Tiantaishan, Tietais manufacturer,
to distribute Tietai.

Baolijin (

LOGO). Baolijin is our recombinant human granulocyte colony-stimulating factor, or G-CSF product. G-CSF is a protein that stimulates production of white blood cells. For cancer patients undergoing chemotherapy, the
ability to produce red blood cells, white blood cells and platelets is severely compromised. Baolijin is indicated for the treatment of neutropenia, a condition associated with chemotherapy and characterized by low levels of neutrophils, a type of
white blood cell important for fighting infections. The addition of Baolijin to our product portfolio enhances our capability to meet the unmet medical needs in supportive cancer care. According to IMS Health, the annual sales for G-CSF products in
China were approximately RMB827 million in 2006.

In August 2006, we entered into an exclusive promotion and distribution agreement
with Chengdu Institute of Biological Products, or the CIBP, to in-license nationwide exclusive rights to market and distribute Baolijin in China from August 1, 2006 to December 31, 2011. Pursuant to this agreement, we purchase Baolijin
from CIBP at certain established prices and are subject to a minimum volume requirement of 150,000 units from August 1, 2006 to December 31, 2007. For each calendar year thereafter during the term of the agreement, the minimum volume
requirement increases by 30% incrementally. If we achieve the minimum purchase requirements during the term of the agreement, we will have the priority right to renew the agreement upon its expiry and obtain the agency right of any other new product
developed by CIBP. Due to significantly increased competition and low pricing structure, we no longer sell the product in China.

Our Product Candidates

NuPIAO

We expect to
complete in 2008 pre-clinical testing and file an Investigation New Drug application with the SFDA to obtain approval for initiating clinical trials for NuPIAO, our second-generation EPIAO that is designed to have a longer half life and is expected
to be comparable in structure to Amgens Aranesp. Aranesp (darbepoietin alpha) is a novel erythropoiesis-stimulating protein with a longer circulating half-life than EPO and is currently the only second-generation EPO product approved by the US
FDA. By using molecular biology and recombinant DNA techniques, we synthesized a series of novel erythropoiesis-stimulating proteins and identified NuPIAO through an activity screening assay. Preliminary testing of NuPIAO has demonstrated an
enhanced half-life comparable to the half-life of darbepoietin alpha.

The effect of extended half-life and increased biologic activity as
compared with EPIAO would allow for less frequent administration, which is more convenient for both patient and caregiver. We have already filed a patent application in China for NuPIAO.

High-Dose EPIAO

In 2007, we completed enrollment registration of patients for a clinical
trial for our 36,000 IU/vial formulation of EPIAO, which is an initial step in the trial process. This product is designed for rapid restoration of hemoglobin to normal levels among cancer patients. If our clinical trial results are positive, we
plan to file an application for SFDA approval of the high-doage EPIAO in the second half of 2008. There currently is no dosage form of this kind on the market in China. In 2006, we initiated a randomized placebo-controlled clinical trial in 200
cancer patients undergoing chemotherapy. In this trial, 100 patients are administered with a 36,000 IU/vial EPIAO once a week for eight weeks. The control group is administered the 10,000 IU/vial EPIAO once every other day. The primary endpoint is
the restoration of hemoglobin levels.

TPIAO for the treatment of ITP

ITP is characterized by thrombocytopenia that results in bruising and bleeding that can be severe. In certain ITP patients, the immune system
malfunctions, perceiving the bodys platelets as foreign and destroying them, potentially resulting in dangerously low platelet counts. Platelets are disc-shaped cells in blood that assist in the clotting process to stop bleeding. TPIAO is
being investigated as a new approach to treat ITP by stimulating the TPO receptor, directly increasing platelet production to outpace platelet destruction by the immune system.

We have designed a Phase III clinical trial to study TPIAO for the treatment of ITP. The Phase III trial will be a multicenter, randomized,
placebo-controlled study in 120 ITP patients. All patients will be administered Danazol, a synthetic steroid hormone drug routinely used to treat ITP. The treatment group will be administered an additional 1.0 μg (or microgram)/kg TPIAO once
daily for 14 days. The primary endpoint of this trial is the measurement of platelet counts during the 14 day treatment. We expect to file for SFDA approval by the end of 2008.

NuLeusin (IL-2)

NuLeusin, our second-generation IL-2, is a genetically modified form of IL-2
possessing the same properties as naturally occurring IL-2. It is capable of activating the immune system to recognize and eliminate certain kinds of cancer cells. The genetic modification enabled us to produce a high dosage form of IL-2 that has
increased stability, which we believe has superior efficacy and tolerable therapeutic reactions profile. We believe NuLeusin is comparable to Chirons Proleukin, which received US FDA approval for treatment of metastatic renal cell carcinoma in
1992, and for treatment of metastatic melanoma in 1998.

In 2005, we completed an open-label, nonrandomized Phase II trial of Nuleusin in
22 patients with metastatic renal cell carcinoma. Patients were treated subcutaneously with Nuleusin every 12 hours for the first five days and then daily for five weeks. The primary endpoints were whether the patients respond to the treatment in
terms of the reduction in size of their tumors after receiving treatment. The data demonstrated that Nuleusin effectively reduced the size of the tumors in these patients. There were no serious adverse events reported in this study.

We are currently conducting a multicenter, open-label Phase III clinical study for NuLeusin for the treatment of metastatic melanoma and metastatic renal
cell carcinoma. We plan to file for SFDA approval in the second half of 2008.

SSS08 (HPV Vaccine)

HPV is a common virus that is often passed on through genital contact, typically during sexual contact. At least 50% of sexually active people will get
HPV at some time in their lives. About 40 types of HPV can infect the genital areas of men and women. While most strains of HPV cause no symptoms and resolve without treatment, some strains of HPV can cause cervical cancer in women.

Worldwide, cervical cancer is the second most common cancer in women; and according to the US FDA, it is estimated to cause, on average, over 470,000 new
cases and 233,000 deaths each year. In the majority of developing countries, cervical cancer remains the number one cause of cancer-related deaths among women, with women in developing countries accounting for approximately 85% of both the yearly
cases and deaths from cervical cancer worldwide.

In 1995, scientists from Merck & Co., Inc. and MedImmune Inc. separately
demonstrated that expression of the papilloma virus major capsid gene L1 alone, or together with the minor capsid protein L2, is sufficient for the generation of virus-like particles, or VLPs. VLPs mimic in some aspects the infection with virions
and induce virus-neutralizing antibodies, making them an attractive candidate for developing a prophylactic vaccine against HPV infections. In June 2006, Merck received approval from the US FDA for its vaccine targeting four strains of HPV that
cause approximately 70% of cervical cancers and approximately 90 percent of genital warts. Our HPV vaccine candidate also targets VLPs of HPV-16 and HPV-18.

SSS07 (Rheumatoid arthritis and other autoimmune diseases)

SSS07 is our anti-TNF monoclonal antibody product candidate that we plan to develop in collaboration with Epitomics, Inc., a United States-based
biotechnology company. Tumor necrosis factor a (TNF) is one of the key chemical messengers that help regulate the inflammatory process and plays an important role in the underlying mechanisms of conditions such as
rheumatoid arthritis, psoriasis, and many other inflammatory disorders. When the body produces too much TNF, it overwhelms the immune systems ability to control inflammation of the joints or of psoriasis-affected skin areas. The TNF inhibitors
are molecules that disrupt the TNF function by blocking the binding of TNF to the TNF receptors. Blockage of these receptors can result in a significant reduction in inflammatory activity and reduce symptoms, inhibit the progression of structural
damage, and improve physical function in patients with moderate to severe rheumatoid arthritis. SSS07 is a genetically engineered anti-TNF humanized monoclonal antibody designed to bind and deactivate certain TNF molecules. By binding to the native
TNF molecule, SSS07 is designed to prevent activation of the inflammation signalling cascade. Several TNF inhibitors developed by other companies have been approved by the US FDA, including Enbrel (entanercept), Remicade (infliximab) and Humira
(adalimumab). According to Evaluate Pharma, the total worldwide sales for this product category in 2005 were approximately US$8.2 billion, a significant majority of which came from the United States and European markets. According to Nature
Biotechnology, the total worldwide sales for this product category in 2006 were approximately US$10.0 billion.

We are currently developing
our anti-TNF monoclonal antibody product candidate in collaboration with Epitomics, Inc., a United States-based biotechnology company that is recognized for its proprietary high-affinity rabbit monoclonal antibody technology. In March 2006, we
entered into a collaboration agreement with Epitomics Inc. under which we were granted an exclusive, royalty bearing, non-transferable and perpetual license in the field of therapeutic usage in order to develop and conduct clinical trials to obtain
SFDA approval for the humanized rabbit anti-TNF alpha monoclonal antibody compounds. Under the agreement, we were also granted the right to manufacture, sell, market and distribute (including distributions by engaging third parties) in China
anti-TNF alpha monoclonal antibody therapeutics covered under the intellectual property rights owned by Epitomics. We were required to pay an upfront lump sum fee and a royalty payment equivalent to a certain percentage of the net sales of
therapeutic products should they reach market. Under the agreement, we granted Epitomics the right to use all intellectual property generated during the development of the therapeutic product. However, if Epitomics uses this intellectual property
for the development of the same therapeutic product outside of China, Epitomics shall pay us a royalty equivalent to a certain percentage of the financial benefit from licenses and product sales. If any new developments or agents are created as a
result of the collaboration agreement, we will grant to Epitomics a right of first refusal with regard to the commercialization of such agents. The details of a development program to commercialize the therapeutic products and the
mechanism for calculating the royalties will be determined between Epitomics and us at a later date.

Marketing, Sales and Distribution

We maintain a sales and marketing force in 30 provinces and major cities in China, including the municipalities of Beijing and Shanghai and the city of
Guangzhou. As of December 31, 2007, our principal products EPIAO and TPIAO were marketed by our 194 sales and marketing professionals and sold by our network of approximately 150 distributors to healthcare providers including, based on our
internal estimates, approximately 1,600 hospitals, clinics and dialysis centers. Our internal sales and marketing staff details our principal products to physicians and hospital administrators, and as required by PRC laws, our distributors are
engaged to contract with our customers for the sale of our principal products to physicians and hospitals. In addition, our legacy products Intefen and Inleusin are marketed, as well as sold, by distributors.

We select our distributors based on their reputation, market coverage and sales experience. We conduct credit assessments of each of our distributors or
hospital customers before we enter into a purchase agreement. We do not have an exclusive distribution arrangement with any of our distributors, and some of our distributors market competing brands. For every calendar year, we enter into a
distribution agreement with each distributor which provides general terms for the distribution arrangement, such as the designated sales area, place and



41



---

method for delivery, targets for annual sales volume and receivable collection. Under our standard distribution agreement, a distributor cannot sell our
products outside the designated geographical area without first obtaining our written consent. The term of a distributor contract is typically for one year, reflecting the prevailing pricing arrangement under the local competitive bidding process.
The price under the agreement may be adjusted by a number of factors, such as the outcome of the competitive bidding process, or regulatory changes during the calendar year.

Hospitals in China typically purchase medical products on credit and sometimes do not make payment until more than a year after the purchase. By
contrast, the average credit terms that we give to our distributors range from 60 days to 180 days, with the majority averaging around 90 days from the date of our delivery, regardless of whether payments from the hospital to the distributors are
received. We believe by selling our products through distributors, we achieve an improved collection rate on our accounts receivable and reduce bad debt expense.

We have a sales department centered in Beijing. We also have a marketing department located in Shanghai, with 11 full-time professionals responsible for product development. In our headquarters in Shenyang, we have 19
employees responsible for product distribution, shipment and handling, and the management of account receivables.

We have established
relationships with many hospital administrators at prominent hospitals and other leading medical institutions, many of whom we believe are advocates for our products. We believe our relationships with these major hospitals and medical institutions
raise our profile, enhance awareness of our products in the medical community, medical equipment and supplies industry and among patients, provide us with valuable clinical data to improve our products and keep us abreast of industry trends and
developments, all of which in turn helps us market and sell our products. In 2007, much of our sales and marketing efforts were focused on educating doctors and clinicians on the value and benefits of EPO in the oncology setting.

Customer and supplier concentration

Sales to
our top ten distributors accounted for approximately 50%, 54% and 53% of our total revenues for the years ended December 31, 2005, 2006 and 2007, respectively.

Our top five suppliers and the single largest supplier as percentages of our overall cost of revenues were 16.8% and 5.0%, respectively, for the year ended December 31, 2007. We primarily source our raw materials
from a variety of international suppliers through their local distributors. We do not anticipate any significant fluctuations in price or any significant disruptions in the supply of our raw materials in the near future. We believe that our
switching cost for our suppliers is not high because alternative suppliers are readily available.

Research and Development

As of December 31, 2007, our research and development team consisted of 22 research personnel and medical professionals. Our research and development
staff consists of medical and biotechnology professionals, including two PhDs, two MDs and seven holders of masters degrees, many of whom have experience in the healthcare and biotechnology research fields, including experience working in
research institutions and hospitals and in proceeding through the SFDA drug approval process.

We conduct our research and development
activities in our facilities in Shenyang. To date, our primary sources of new clinical products have been our internal research and development activities and the licensing of compounds from third parties. We believe by complementing our internal
research and development efforts with a disciplined strategy of entering into collaborative relationships, we can build a pipeline of diversified pharmaceuticals to drive sustainable revenue growth. For a detailed description of our product
pipeline, see Our Product Pipeline above.

Our research and development expenses for the years ended December 31,
2005, 2006 and 2007 were RMB3.2 million, RMB6.1 million and RMB11.6 million (US$1.6 million), respectively.

Intellectual Property

We expect that we will, in the future, rely on patents to protect our proprietary technology. While we currently expect to seek patent protection only in China, we may opportunistically seek patents to protect our
innovations in other jurisdictions in the future. In China, patents relating to pharmaceutical inventions are effective for 20 years from the date the patent application is filed.

We currently own five issued PRC patents relating to:



| |  |  | the composition of matter of TPIAO, expiring in 2015;
| | - |  | -----------------------------------------------------



| |  |  | a method of manufacturing TPIAO, expiring in 2020;
| | - |  | --------------------------------------------------



| |  |  | a method and application thereof relating to our manufacturing processes, expiring in 2021;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | a formulation of Interferon-alpha that does not relate to our marketed products, expiring in 2022; and
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | a formulation of EPIAO, expiring in 2023.
| | - |  | -----------------------------------------

We have also filed two pending PRC patent applications relating to manufacturing of interleukin analogues and a novel erythropoiesis stimulating protein analogue. We do not own any foreign patents and have not filed any patent applications
outside of the PRC. In addition, we own 11 registered trademarks relating to EPIAO, TPIAO, Intefen and Inleusin.

We are aware of
intellectual property rights held by third parties that relate to products or technologies we are developing. For example, we are aware of a patent held by a third party that may relate to our TPIAO product. We believe, as to each claim in this
patent, that we either do not infringe the claim of the patent or that the claim is invalid. While the validity of issued patents, patentability of pending patent applications and applicability of any of them to our programs are uncertain, if
asserted against us, any related patent rights could adversely affect our ability to commercialize our products.

We also rely on trade
secrets, proprietary know-how and continuing technological innovation to develop and maintain a competitive position in our product areas. We generally require our employees, consultants and advisors to enter into confidentiality agreements. These
agreements provide that all confidential information developed or made known to the individual during the course of the individuals relationship with us is to be kept confidential and not disclosed to third parties except under specific
circumstances. In the case of our employees, the agreements provide that all of the technology which is conceived by the individual during the course of employment is our exclusive property. The development of our technology and many of our
processes are dependent upon the knowledge, experience and skills of key scientific and technical personnel. Further, as a matter of company policy, all scientific and technical employees have entered into agreements that generally require
disclosure and assignment to us of ideas, developments, discoveries and inventions made by them. However, these agreements may not effectively prevent disclosure of our confidential information or provide meaningful protection for our confidential
information if there is unauthorized use or disclosure.

The research, development and commercialization of a biopharmaceutical often
involve alternative development and optimization routes, which are presented at various stages in the development process. The preferred routes cannot be predicted at the outset of a research and development program because they will depend upon
subsequent discoveries and test results. There are numerous third-party patents in our field, and it is possible that to pursue the preferred development route of one or more of our products we will need to obtain a license to a patent, which would
decrease the ultimate profitability of the applicable product. If we cannot negotiate a license, we might have to pursue a less desirable development route or terminate the program altogether. PRC patent and trademark laws are discussed in greater
detail in RegulationsPatent and trademark protection.

We cannot assure you that any of our intellectual properties
will be able to provide us with meaningful protection or commercial advantages. Despite any measures we take to protect our intellectual property, no



43



---

assurance can be made that unauthorized parties will not attempt to copy aspects of our products, manufacturing processes or our proprietary technology or to
otherwise obtain and use information that we regard as proprietary. The protection of intellectual property rights and proprietary information in China may not be as effective as in the United States or other countries. For example, implementation
and enforcement of PRC intellectual property-related laws have historically been deficient and ineffective and may be hampered by corruption and local protectionism. Policing unauthorized use of proprietary technology is difficult and expensive, and
we might need to resort to litigation to enforce or defend patents issued to us or to determine the enforceability, scope and validity of our proprietary rights or those of others. The experience and capabilities of PRC courts in handling
intellectual property litigation varies, and outcomes are unpredictable. Further, such litigation may require significant expenditure of cash and management efforts and could harm our business, financial condition and results of operations.

To date, we have not been involved in any significant intellectual property disputes or encountered major difficulties in enforcing our
intellectual property rights in China.

Manufacturing

Our Shenyang-based manufacturing operations consist of bulk manufacturing and formulation, fill and finish activities for the production of EPIAO, TPIAO, Intefen, Inleusin and other product candidates for both
clinical and commercial purposes. We also manufacture our product candidates for clinical trials at this facility. All fill, finish and packaging activities in relation to our domestic sales are conducted at our Shenyang facility. A portion of our
exported products are packaged in our Shenyang facility, and the rest is shipped overseas in bulk format as concentrated solutions of recombinant human erythropoietin, interferon alpha-2a or interleukin-2 and finished and packaged locally. Our
Shenyang facility is re-certified in accordance with Chinese current GMP, and such GMP certificate is valid for five years, until 2010. We specialize in manufacturing proteins with mammalian expression systems, although we are capable of
manufacturing with bacterial expression systems. Our facilities give us the capability to manufacture products at up to 105-grams scale using bacterial production systems for our legacy products and up to 270-grams scale using mammalian cell
expression systems for EPIAO and TPIAO. We generally produce our products based on quarterly order forecasts and anticipated additional orders that we are reasonably confident will be obtained. Lead times for raw materials and components vary and
depend on the specific supplier and the availability and demand for the raw materials. Raw materials and supplies are generally available from various suppliers in quantities adequate to meet our needs. However, we have single-source suppliers for
some components and value-added steps, including EPO Elisa Kit by R&D systems Inc, GIBCO cell culture medium by Invitrogen Inc., Pharmacia chromatography purification medium by GE Healthcare, a division of GE, and Disc, a microcarrier for cell
cultures, by New Brunswick Scientific Inc. We have not experienced any disruptions in the supply of these raw materials in the past. Unlike in the United States, we do not need SFDA approval to change suppliers. In the event that any one of these
supply arrangements or agreements is terminated or the ability of any one of these suppliers to perform under our agreements were to be materially adversely affected, we believe that we will be able to locate, qualify and enter into an agreement
with a new supplier on a timely basis. We maintain long-term relationships with most of our suppliers and place orders from these suppliers from time to time on an as-needed basis. We expect that our existing manufacturing facilities and outside
sources will allow us to meet near-term manufacturing needs for our commercial products and other products that are in clinical trials.

We
have long-term relationships with certain of our sole suppliers and periodically place orders to specify the price, specifications, quantity and time of delivery for raw materials on an as-needed basis. For example, Invitrogen Inc. is our single
largest raw material supplier of BPT-6N medium. On December 6, 2004, we entered into a one-time purchase agreement with Invitrogen (GIBCO) Shanghai Representative Office to purchase customer-made BPT-6N media with a 30% down payment and 70%
payment upon delivery of the total purchase price. On March 8, 2006, we entered into another one-time purchase agreement with Invitrogen Hong Kong Co., Ltd. to purchase customer-made BPT-6 culture medium with a 30% down payment and 70% payment
upon delivery of the total purchase price. Under the March 8, 2006 agreement, we agreed not to resell such product to



44



---

any third party. Shanghai Weike Biochemical Reagent Co. Ltd., or Weike, is our third largest raw material supplier of fetal calf serum, or FCS. On
April 12, 2005, we entered into a one-time purchase agreement to purchase FCS with payment to be made within 30 days upon delivery of each bulk of the products.

As part of our overall strategy to increase our manufacturing capacity, we plan to expand our plant in Shenyang and have acquired the land and drafted the plans to execute on this strategy.

Quality Control and Assurance

We have our own
independent quality control system and devote significant attention to quality control for the designing, manufacturing and testing of our products. We have established a quality control system in accordance with SFDA regulations. Our four
laboratories fully comply with the Chinese GMP guidelines and are staffed with highly educated and skilled technicians to ensure quality of all batches of product release. We implemented European Pharmacopoeia 2002 version on quality control in
2004. European Pharmacopeia of the Council of Europe is a wide range of active substances and excipients used to prepare pharmaceutical products in Europe.

Our quality assurance team is also responsible for ensuring that we are in compliance with all applicable regulations, standards and internal policies. Our senior management team is actively involved in setting
quality policies and managing internal and external quality performance.

Certificates and Permits

Our pharmaceutical manufacturing enterprise permit was issued by Liaoning Food and Drug Administration, or Liaoning FDA, on January 1, 2006 and will
expire on December 31, 2010. Liaoning Sunshines pharmaceutical distribution enterprise permit was issued by Liaoning FDA on January 1, 2005 and will expire on December 31, 2009. Our GMP certificate in relation to TPIAO was
issued by the SFDA on July 29, 2005 and will expire on July 28, 2010. Our GMP certificate in relation to EPIAO and our legacy products was issued by the SFDA on April 14, 2005 and will expire on April 14, 2010.

Competition

The market for protein therapeutics is
competitive and rapidly evolving on a global basis. Increased competition has resulted in industry-wide price reductions or reduced margins. In particular, we face competition from domestic and foreign pharmaceutical companies in each of our
potential product areas. Certain of these companies may have substantially greater capital and research and development resources, more advanced facilities, greater experience in conducting clinical trials and obtaining regulatory approvals, and
greater experience and expertise in developing and commercializing products. In China, our EPIAO competes primarily with Kirins ESPO, Roches Recormon and Yi Pei by Diao Group Chengdu Diao Jiuhong Pharmaceutical Factory.
Competitors for interleukin-2 in China include Beijing SL Pharmaceutical Co., Ltd. and Beijing Four Rings Biopharmaceutical Co., Ltd. Competitors for Tietai Iron Sucrose Supplement in China include Beijing Novartis Pharmaceutical Co., Ltd. and
Nanjing Hencer Pharmaceutical Co., Ltd., and competitors for Baolijin in China include Kirin, Hangzhou Jiuyuan Gene Engineering Co., Ltd. and Qilu Pharmaceutical Co., Ltd.

We believe that competition and leadership in our industry are based on managerial and technological superiority, and the ability to identify and exploit
commercially viable products. Other factors affecting our competitive position include time to market, patent position, product efficacy, safety, convenience, reliability, availability and pricing. We believe we are well positioned to compete in the
fast-developing Chinese protein-based market with our strong Shenyang Sunshine brand, diverse product portfolio, proven research and development capabilities, established sales and marketing network and favorable cost structure.

Facilities

Our state-of-art manufacturing facilities are located in the Shenyang Economy & Technology Development Zone, where we own three buildings with an aggregate of approximately 3,000 square meters of office, research and development
and manufacturing spaces, including cleanrooms of approximately 1,600 square meters. Our facilities in Shenyang consist of three separate divisions capable of producing bulk products, including bacterial expressed proteins and manufacturing
expressed proteins, and formulating final products. Our manufacturing facilities are equipped with state-of-art and top-line branded equipment, such as bioreactors, centrifuges, chromatography systems and lyophilizers. We own all of our
manufacturing facilities in Shenyang. We believe that our existing facilities are adequate to meet our current and foreseeable future requirements within three years. We are building new manufacturing facilities in Shenyang to meet increased demand
for our products. We have purchased the relevant land use rights, completed design of such manufacturing facilities and are currently conducting an evaluation of the manufacturing facilities to meet EMEA requirements. We target to complete the
construction of the new manufacturing facilities by the end of 2009.

Employees

We had 272, 313 and 373 employees as of December 31, 2005, 2006 and 2007, respectively. The following table sets forth the number of our employees
categorized by function as of December 31, 2007:



|                           |  |                        
|-------------------------- |  | -----------------------
|                           |  | As of December 31, 2007
|Manufacturing and services |  | 81                     
|Research and development   |  | 22                     
|General and administration |  | 76                     
|Marketing and sales        |  | 194                    
|                           |  |                        
|Total                      |  | 373                    
|                           |  |                        

From time to time, we also employ independent contractors to support our marketing and sales and
clinical support and research. We plan to hire additional employees for marketing and sales, customer service and manufacturing and assembly as we grow our business. None of our employees is represented by a labor union and we consider our
relationship with our employees to be good.

In accordance with applicable regulations in the PRC, we participate in a pension contribution
plan, a medical insurance plan, an unemployment insurance plan and a personal injury insurance plan for our employees. We have made adequate provisions in accordance with applicable regulations, which required us to contribute amounts equal to
17.7%, 15.5% and 16.0%, respectively, of our employees aggregate base salaries to these statutory plans for the years ended December 31, 2005, 2006 and 2007.

Also, in accordance with PRC regulations, we contributed amounts equal to 3.8%, 3.6% and 3.8% of our employees aggregate base salaries towards a housing fund, a supplemental medical insurance fund and a
maternity fund, respectively, for the years ended December 31, 2005, 2006 and 2007.

Regulations

The pharmaceutical industry is heavily regulated in the PRC. This section summarizes the principal PRC regulations relating to our business.

Regulatory authorities

In the PRC, the State
Food and Drug Administration, or the SFDA, is the authority that monitors and supervises the administration of pharmaceutical products and medical appliances and equipment as well as food, health food and cosmetics. The SFDAs predecessor,
the State Drug Administration, or the SDA, was established



46



---

on August 19, 1998 as an organization under the State Council to assume the responsibilities previously handled by the MOH, the State Pharmaceutical
Administration Bureau of the PRC and the State Administration of Traditional Chinese Medicine of the PRC. The SFDA was founded in March 2003 to replace the SDA and reported to the State Council until the MOH was reorganized and assumed
administrative responsibility for the SFDA in March 2008.

The primary responsibilities of the SFDA include:



| |  |  | monitoring and supervising the administration of pharmaceutical products, medical appliances and equipment as well as food, health food and cosmetics in the PRC;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | formulating administrative rules and policies concerning the supervision and administration of food, health food, cosmetics and the pharmaceutical industry;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | evaluating, registering and approving of new drugs, generic drugs, imported drugs and traditional Chinese medicine;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | approving and issuing permits for the manufacture and export/import of pharmaceutical products and medical appliances and equipment and approving the establishment
of enterprises to be engaged in the manufacture and distribution of pharmaceutical products; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | examining and evaluating the safety of food, health food and cosmetics and handling significant accidents involving these products.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------

The MOH is an authority at the ministerial level under the State Council and is primarily responsible for national public health. Following the
establishment of the SFDA in 2003, the MOH was put in charge of the overall administration of the national health in the PRC excluding the pharmaceutical industry. In March 2008, the MOH was reorganized and assumed administrative responsibility for
the SFDA. The MOH performs a variety of tasks in relation to the health industry such as establishing social medical institutes and producing professional codes of ethics for public medical personnel. The MOH is also responsible for overseas
affairs, such as dealings with overseas companies and governments.

Drug administration laws and regulations

The PRC Drug Administration Law as promulgated by the Standing Committee of the National Peoples Congress in 1984 and the Implementing Measures of
the PRC Drug Administration Law as promulgated by the MOH in 1989 have laid down the legal framework for the establishment of pharmaceutical manufacturing enterprises, pharmaceutical trading enterprises and for the administration of pharmaceutical
products including the development and manufacturing of new drugs and medicinal preparations by medical institutions. The PRC Drug Administration Law also regulates the packaging, trademarks and the advertisements of pharmaceutical products in the
PRC.

Certain revisions to the PRC Drug Administration Law took effect on December 1, 2001. They were formulated to strengthen the
supervision and administration of pharmaceutical products, and to ensure the quality of pharmaceutical products and the safety of pharmaceutical products for human use. The revised PRC Drug Administration Law applies to entities and individuals
engaged in the development, production, trade, application, supervision and administration of pharmaceutical products. It regulates and prescribes a framework for the administration of pharmaceutical manufacturers, pharmaceutical trading companies,
medicinal preparations of medical institutions and the development, research, manufacturing, distribution, packaging, pricing and advertisements of pharmaceutical products.

The PRC Drug Administration Implementation Regulations promulgated by the State Council took effect on September 15, 2002 to provide detailed
implementation regulations for the revised PRC Drug Administration Law.

Examination and approval of new medicines

In October 2002, the SFDA announced the Administrative Measures on the Registration of Pharmaceutical Products, which were later revised on
February 28, 2005 and subsequently replaced by the new Administrative Measures on the Registration of Pharmaceutical Products on October 1, 2007. Under the current applicable regulations, new medicines generally refer to those medicines
that have not yet been marketed in the PRC. In addition, certain marketed medicines may also be treated as new medicines if the type or application method of such medicines has been changed or new therapeutic functions have been added to such
medicines. According to the prevailing Administrative Measures on the Registration of Pharmaceutical Products, the approval of new medicines requires the following steps:



| |  |  | Upon completion of the pre-clinical research of the new medicine, application for registration of the new medicine shall be submitted to the drug regulatory
authorities at the provincial level for review. After completion of its review the drug regulatory authorities at the provincial level shall submit their opinion and report to the SFDA for review;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if all the requirements are complied with, the SFDA will issue a notice of acceptance of application and proceed with its assessment on whether or not to grant the
approval for conducting the clinical research on the new medicine;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | after obtaining the SFDAs approval for conducting the clinical research, the applicant may proceed with the relevant clinical research (which is generally
conducted in three phases for a new medicine under the Medicine Registration Measures) at institutions with appropriate qualification:
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Phase I refers to the preliminary clinical trial for clinical pharmacology and body safety. It is conducted to observe the human body tolerance for new medicine and
pharmacokinetics, so as to provide a basis for determining the prescription plan.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Phase II refers to the stage of preliminary evolution of clinical effectiveness. The purpose is to preliminarily evaluate the clinical effectiveness and safety of
the medicine used on patients with targeted indication, as well as to provide a basis for determining the Phase III clinical trial research plan and the volume under the prescription plan.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Phase III is a clinical trial stage to verify the clinical effectiveness. The purpose is to test and determine the clinical effectiveness and safety of the medicine
used on patients with targeted indication, to evaluate the benefits and risks thereof, and, eventually, to provide sufficient basis for review of the medicine registration application.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | after completion of the relevant clinical research, the applicant shall submit its clinical research report together with the relevant supporting documents to the

| |  |  | if all the regulatory requirements are satisfied, the SFDA will grant a new drug certificate and a pharmaceutical approval number (assuming the applicant has a
valid pharmaceutical manufacturing permit and the requisite production conditions for the new medicine have been met).
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Permits and
licenses for manufacturing and registration of drugs

Production License. To manufacture pharmaceutical products in the PRC,
a pharmaceutical manufacturing enterprise must first obtain a pharmaceutical manufacturing permit issued by the relevant pharmaceutical



48



---

administrative authorities at the provincial level where the enterprise is located. Among other things, such a permit must set forth the permit number, the
name, legal representative and registered address of the enterprise, the site and scope of production, issuing institution, date of issuance and effective period.

Each pharmaceutical manufacturing permit issued to a pharmaceutical manufacturing enterprise is effective for a period of five years. Any enterprise holding a pharmaceutical manufacturing permit is subject to review
by the relevant regulatory authorities on an annual basis. The enterprise is required to apply for renewal of such permit within six months prior to its expiry and will be subject to reassessment by the issuing authorities in accordance with then
prevailing legal and regulatory requirements for the purposes of such renewal.

Business Licenses. In addition to a
pharmaceutical manufacturing permit, the manufacturing enterprise must also obtain a business license from the administrative bureau of industry and commerce at the local level after it has obtained the requisite pharmaceutical manufacturing permit.
The name, legal representative and registered address of the enterprise specified in the business license must be identical to that set forth in the Pharmaceutical manufacturing permit.

Registration of Pharmaceutical Products. All pharmaceutical products that are produced in the PRC must bear a registered number issued by the
SFDA in the PRC, with the exception of Chinese herbs and Chinese herbal medicines in soluble form. The medicine manufacturing enterprises must obtain the medicine registration number before manufacturing any medicine.

GMP Certificates. The World Health Organization encourages the adoption of GMP standards in pharmaceutical production in order to minimize
the risks involved in any pharmaceutical production that cannot be eliminated through testing the final products.

The Guidelines on Good
Manufacturing Practices, as amended in 1998, or the Guidelines, took effect on August 1, 1999 and set the basic standards for the manufacture of pharmaceuticals. These Guidelines cover issues such as the production facilities, the qualification
of the staff at the management level, production plant and facilities, documentation, material packaging and labeling, inspection, production management, sales and return of products and customers complaints. On October 23, 2003, the SFDA
issued the Notice on the Overall Implementation and Supervision of Accreditation of Good Manufacturing Practice Certificates for Pharmaceuticals, which required all pharmaceutical manufacturers to apply for the GMP certificates by June 30,
2004. Those enterprises that failed to obtain the GMP certificates by December 31, 2004 would have their pharmaceutical manufacturing permit revoked by the drug administrative authorities at the provincial level. The GMP certificate is valid
for a term of five years and application for renewal must be submitted six months prior to its expiration date.

Administrative protection and
monitoring periods for new drugs

In April 1999, the SFDA promulgated the Regulations for New Drug Protection and Related Technology
Transfer, or the 1999 Regulations, which provided a six to twelve year administrative protection period for different categories of new drugs. During the protection period of a new drug manufactured by a specific pharmaceutical company, other
enterprises or individuals are prohibited from manufacturing a similar drug or expanding the label of any existing drug to include the same indication. In December 2002, the 1999 Regulations were replaced by the Administrative Measures on the
Registration of Pharmaceutical Products, or the 2002 Regulations, which were later revised in February 2005. However, according to an official notice of the SFDA, administrative protection periods granted prior to September 2002 pursuant to the 1999
Regulations will stay valid until their respective expiration dates.

According to the 2002 Regulations, with a view to protecting public
health, the SFDA may provide for administrative monitoring periods of up to five years for new drugs approved to be manufactured, to continually monitor the safety of those new drugs. The key element in determining the availability and duration of
the



49



---

monitoring period is the safety of the new drug. The SFDA will consider, among other things, whether the new drug has been previously launched domestically
or overseas, what type of new drug it is and what process and technology are involved in the production of the new drug. For example, for a biochemical product that has never been launched domestically or overseas, a five-year monitoring period will
be granted; for a biochemical product that has been launched overseas but not domestically, only a four-year monitoring period will be granted.

During the monitoring period of a new drug, the SFDA will not approve any other enterprises application to manufacture or import a similar new drug. The only exception is that the SFDA will continue to handle any application if, prior
to the commencement of the monitoring period, the SFDA has already approved the applicants clinical trial for a similar new drug. If such application conforms to the relevant provisions, the SFDA may approve such applicant to manufacture or
import the similar new drug during the remainder of the monitoring period.

Any applicant who is not satisfied with the SFDAs
decision can appeal within ten days of its receipt of the SFDAs decision. If the applicant is dissatisfied with the result of the appeal, it may apply for an administrative review with a special committee consisting of senior officials of the
SFDA or file an administrative lawsuit with a peoples court in China.

Distribution of pharmaceutical products

According to the PRC Drug Administration Law and its implementing regulations and the Administrative Measures on Oversight of Distribution of
Pharmaceutical Products, a manufacturer of pharmaceutical products in the PRC can only engage in the trading of the pharmaceutical products that the manufacturer has produced itself. In addition, such manufacturer can only sell its products to:



| |  |  | wholesalers and distributors holding Pharmaceutical trading permits;
| | - |  | --------------------------------------------------------------------



| |  |  | other holders of pharmaceutical manufacturing permits; or
| | - |  | ---------------------------------------------------------



| |  |  | medical practitioners holding Medical practice permits.
| | - |  | -------------------------------------------------------

A pharmaceutical manufacturer in the PRC is prohibited from selling its products to end-users, or individuals or entities other than holders of Pharmaceutical trading permits, the pharmaceutical manufacturing permits
or the Medical practice permits.

The granting of a Pharmaceutical Trading Permit to wholesalers shall be subject to approval of the
provincial level FDA, while the granting of a retailer permit shall be subject to the approval of the FDA above the county level. Unless otherwise expressly approved, no pharmaceutical wholesaler may engage in the retail of pharmaceutical products,
and neither may pharmaceutical retailers engage in wholesale.

A pharmaceutical distributor shall satisfy the following requirements:



| |  |  | Personnel with pharmaceutical expertise as qualified according to law;
| | - |  | ----------------------------------------------------------------------



| |  |  | Business site, facilities, warehousing and sanitary environment compatible to the distributed pharmaceutical products;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | Quality management system and personnel compatible to the distributed pharmaceutical products; and
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | Rules and regulations to ensure the quality of the distributed pharmaceutical products.
| | - |  | ---------------------------------------------------------------------------------------

Operations of pharmaceutical distributors shall be conducted in accordance with the Pharmaceutical Operation Quality Management Rules and shall be
granted a certificate under such rules by the SFDA.

Pharmaceutical distributors must keep true and complete records of any pharmaceutical
products purchased, distributed or sold with the generic name of such products, specification, approval code, term, manufacturer,



50



---

purchasing or selling party, price and date of purchase or sale. A pharmaceutical distributor must keep such record at least until one year after the expiry
date of such products and in any case, such record must be kept for no less than three years. Penalties may be imposed for any violation of record-keeping.

Pharmaceutical distributors can only distribute pharmaceutical products obtained to those with a pharmaceutical manufacturing permit and a Pharmaceutical Trading Permit.

Price control

The administration of price control of
pharmaceutical products is vested in the national and provincial price administration authorities. Depending on the categories of pharmaceutical products in question, the prices of pharmaceutical products listed in the State Basic Medical Insurance
Drug Catalogue, drugs with patents and other drugs whose production or trading may constitute monopolies are subject to the control of the National Development and Reform Commission of the PRC and the relevant provincial or local price
administration authorities. In respect of pharmaceutical products manufactured in the PRC, the national price administration authority from time to time publishes price control lists setting out the names of pharmaceutical products and their
respective price ceilings. The provincial price administration authorities also publish price control lists in respect of the pharmaceutical products which are manufactured within their respective areas. The main purpose of the price control policy
is to set an upper limit to the prices of pharmaceutical products to prevent excessive increases in the prices of such products. Pursuant to the Measures for Medicine Pricing by the Government, the price ceiling is determined mainly by reference to
the quality of the product, whether the products are newly developed products, and the status of implementing the GMP Guidelines by the manufacturer of the relevant product.

The prices of pharmaceutical products included in the price control lists are subject to adjustment upon approval by the price administration authorities
from time to time. Pharmaceutical enterprises in the PRC are required to submit cost related information such as raw material prices regularly to the relevant authorities, so that the authorities could take into account the prevailing market
conditions when setting the prices. The price administration authorities may approve adjustments to the price of pharmaceutical products upon the pharmaceutical manufacturers request if material changes in the cost structure in producing the
pharmaceutical products or significant changes in demand for these pharmaceutical products are recognized.

Product liability

In addition to the strict new drug approval process, certain PRC laws have been promulgated to protect the rights of consumers and to strengthen the
control of medical products in the PRC. Under current PRC law, manufacturers and vendors of defective products in the PRC may incur liability for loss and injury caused by such products. Pursuant to the General Principles of the Civil Law of the
PRC, or the PRC Civil Law, promulgated on April 12, 1986, a defective product which causes property damage or physical injury to any person may subject the manufacturer or vendor of such product to civil liability for such damage or injury.

On February 22, 1993 the Product Quality Law of the PRC, or the Product Quality Law, was promulgated to supplement the PRC Civil Law
aiming to protect the legitimate rights and interests of the end-users and consumers and to strengthen the supervision and control of the quality of products. The Product Quality Law was revised by the Ninth National Peoples Congress on
July 8, 2000. Pursuant to the Product Quality Law, manufacturers who produce defective products may be subject to civil or criminal liability and have their business licenses revoked.

On October 31, 1993, the PRC Law on the Protection of the Rights and Interests of Consumers, or the Consumers Protection Law, was promulgated and
provides further protection to the legal rights and interests of consumers in connection with the purchase or use of goods and services. At present, all business operations must observe and comply with the Consumers Protection Law when they provide
their goods and/or consumer services.

Health insurance system

According to the State Council Decision on the Establishment of the Basic Medical Insurance System of Staff in Cities and Town promulgated by the State Council in December 1998, the Ministry of Labor and Social
Security assumed the responsibilities for the reform of the social medical insurance system. As part of the reform of the state basic medical insurance system for employees in the urban areas, the Ministry of Labor and Social Security, the MOH, the
SDFA and various other governmental departments jointly issued the State Basic Medical Insurance Drug Catalogue with a view to enhancing the management of the use of drugs under the medical insurance system. The drugs listed in the catalogue are
covered by the medical insurance system. The labor and social security authorities at the provincial level may, subject to ratification by the Ministry of Labor and Social Security, make amendments to the list of category B drugs in the catalogue to
a small extent to suit local needs.

PRC patent law

The PRC first allowed patents for the protection of proprietary rights, as set forth in the China Patent Law, in 1985. Pharmaceutical inventions were not patentable under the China Patent Law until 1994. Patents
relating to pharmaceutical inventions are effective for 20 years from the date the patent application is filed.

Patent prosecution

The Chinese patent prosecution system is different from the United States system in a number of ways. The Chinese patent system, like most countries other
than the United States, adopts the principle of first to file. This means that, where more than one person files a patent application for the same invention, a patent will be granted to the person who first filed the application. The
United States uses a principle of first to discover 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, any prior written or oral publication,
demonstration or use before filing the patent application prevents an invention from being patented in the PRC. Conversely, inventors in the United States have a one year grace period after publication of the invention in which they may file a
patent. Patents issued in the PRC are not enforceable in Hong Kong, Taiwan or Macau, each of which has independent patent systems. Patents are filed at the State Intellectual Property Office, or SIPO, in Beijing.

Patent enforcement

A patent holder who believes the
patent is being infringed may either file a civil legal suit or file an administrative complaint with a provincial or municipal office of SIPO. A PRC court may issue a preliminary injunction upon the patent holders or an interested
partys request before instituting any legal proceedings or during the proceedings. Damages for infringement are calculated as either the loss suffered by the patent holder arising from the infringement or the benefit gained by the infringer
from the infringement. If it is difficult to ascertain damages in this manner, damages may be determined in the range of from one to three times of the license fee under a contractual license. If damages cannot still be determined, statutory damages
from RMB5,000 to 500,000 may be requested. As in other jurisdictions, with one notable exception, the patent holder in the PRC has the burden of proving that the patent is being infringed. However, if the holder of a manufacturing process patent
alleges infringement of such patent, the alleged infringing party has the burden of proving that there has been no infringement.

Compulsory license

Under the Patent Law, where a person possesses the means to utilize a patented technology, but such person cannot obtain a license from
the patent holder on reasonable terms and in a reasonable period of time, SIPO is authorized to grant a compulsory license. A compulsory license can also be granted where a national emergency or any extraordinary state of affairs occurs or where the
public interest so requires. We do not believe a compulsory license has yet been granted by the SIPO.

International patent treaties

The PRC is also a signatory to all major intellectual property conventions, including 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 also a large degree 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. 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 the subject of the initial application.

Trademarks

The PRC Trademark Law was
promulgated in 1982, followed by the PRC Trademark Implementing Regulations in 1988, and was amended on October 27, 2001. As noted above, the PRC is signatory to the Madrid Agreement and the Madrid Protocol. These agreements provide a mechanism
whereby an international registration produces the same effects as an application for registration of the mark made in each of the countries designated by the applicant.

The PRC Trademark Office is responsible for the registration and administration of trademarks throughout the country. Like patents, the PRC has adopted a first-to-file principle with respect to trademarks.

PRC law provides that the following acts constitute infringement of the exclusive right to use a registered trademark:



| |  |  | use of a trademark that is identical with or similar to a registered trademark in respect of the same or similar commodities without the authorization of the
trademark registrant;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | sale of commodities infringing upon the exclusive right to use the trademark;
| | - |  | -----------------------------------------------------------------------------



| |  |  | counterfeiting or making, without authorization, representations of a registered trademark of another person, or sale of such representations of a registered
trademark as were counterfeited, or made without authorization;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changing a registered trademark and putting commodities on which the changed registered trademark is used into the market without the consent of the trademark
registrant; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | otherwise infringing upon the exclusive right of another person to use a registered trademark.
| | - |  | ----------------------------------------------------------------------------------------------

In the PRC, a trademark owner who believes the trademark is being infringed has three options:



| |  |  | The trademark owner can provide his trademark registration certificate and other relevant evidence to the State or local administrative bureau of industry and
commerce (AIC) which can, at its discretion, launch an investigation. The AIC may take such actions as order the infringer to immediately cease the infringing behavior, seize and destroy the representations of the trademark in question
and impose a fine. If the trademark owner is dissatisfied with the AICs decision, he may apply to have the decision reconsidered.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The trademark owner may institute civil proceedings directly with a court. Civil redress for trademark infringement includes:
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | injunctions;
| | - |  | ------------



53



---

| |  |  | requiring the infringer to take steps to mitigate the damage (i.e., print notices in newspapers); and
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | damages (i.e. compensation for the economic loss and injury to reputation as a result of trademark infringement suffered by the trademark holder).
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The amount of compensation is calculated according to either the gains acquired by the infringer from the infringement during the infringement, or the loss suffered
by the trademark owner, including expenses incurred by the trademark holder to deter such infringement. If it is difficult to determine the gains acquired by the infringer from the infringement, or the loss suffered by the trademark owner, the court
may elect to award compensation of not more than RMB500,000.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | If the case is so serious as to constitute a crime, the trademark owner may lodge a complaint with the relevant public security organ.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

Other national and provincial level laws and regulations

We are subject to changing regulations under many other laws and regulations administered by governmental authorities at the national, provincial and municipal levels, some of which are or may become applicable to our
business. Our hospital customers are also subject to a wide variety of laws and regulations that could affect the nature and scope of their relationships with us.

For example, regulations control the confidentiality of patients medical information and the circumstances under which patient medical information may be released for inclusion in our databases, or released by
us to third parties. These laws and regulations governing both the disclosure and the use of confidential patient medical information may become more restrictive in the future.

We also comply with numerous additional state and local laws relating to matters such as safe working conditions, manufacturing practices, environmental
protection and fire hazard control. We believe that we are currently in compliance with these laws and regulations; however, we may be required to incur significant costs to comply with these laws and regulations in the future. Unanticipated changes
in existing regulatory requirements or adoption of new requirements could therefore have a material adverse effect on our business, results of operations and financial condition.

Regulation of foreign currency exchange and dividend distribution

Foreign currency exchange

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



| |  |  | the Foreign Currency Administration Rules (1996), as amended, or the Exchange Rules; and
| | - |  | ----------------------------------------------------------------------------------------



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

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

Under the Administration Rules, foreign-invested enterprises in China, such as Shenyang Sunshine, may only buy, sell and/or remit foreign currencies
at those banks authorized to conduct foreign exchange business after providing valid commercial documents and, in the case of capital account item transactions, obtaining approval from the SAFE. Capital investments by foreign-invested enterprises
outside of China are also subject to limitations, which include approvals by the SAFE and other relevant government authorities.



54



---

Dividend distribution

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



| |  |  | the Wholly Foreign Owned Enterprise Law (1986), as amended; and
| | - |  | ---------------------------------------------------------------



| |  |  | the Wholly Foreign Owned Enterprise Law Implementation Rules (1990), as amended.
| | - |  | --------------------------------------------------------------------------------

Under these regulations, foreign-invested enterprises in China may pay dividends only out of their accumulated profits, if any, determined in accordance
with PRC accounting standards and regulations. In addition, foreign-invested enterprises in China are required to set aside certain amounts out of their accumulated profits each year, if any, to fund certain reserve funds, bonus and welfare funds.
These funds are not distributable as cash dividends.

Regulation of foreign exchange in certain onshore and offshore transactions

On October 21, 2005, the SAFE issued the Notice on Issues Relating to the Administration of Foreign Exchange in Fund-raising and Reverse Investment
Activities of Domestic Residents Conducted via Offshore Special Purpose Companies, or Notice No. 75, which became effective as of November 1, 2005.

Pursuant to Notice No.75, prior to establishing or assuming control of an offshore company for the purpose of financing that offshore company with assets or equity interests in an onshore enterprise in the PRC, each
PRC resident who is an ultimate controller, whether a natural or legal person, must complete the overseas investment foreign exchange registration procedures with the relevant local SAFE branch. An amendment to the registration with the local SAFE
branch is required to be filed by any PRC resident that directly or indirectly holds interests in that offshore company upon either the injection of equity interests or assets of an onshore enterprise to the offshore company, or the completion of
any overseas fundraising by such offshore company. An amendment to the registration with the local SAFE branch is also required to be filed by such PRC resident when there is any material change involving a change in the capital of the offshore
company, such as (a) an increase or decrease in its capital, (b) a transfer or swap of shares, (c) a merger or division, (d) a long-term equity or debt investment or (e) the provision of a guarantee to third parties.

Under Notice No. 75, failure to comply with the registration procedures set forth in Notice 75 may result in restrictions being
imposed on the foreign exchange activities of the relevant onshore company, including the payment of dividends and other distributions to its offshore parent or affiliate and the capital inflow from the offshore entity, and may also subject relevant
PRC residents to penalties under PRC foreign exchange administration regulations.

Regulation on overseas listings

On August 8, 2006, six PRC regulatory agencies, including the MOFCOM and the CSRC, jointly adopted the Regulations on Mergers and Acquisitions of
Domestic Enterprises by Foreign Investors, or the New M&A Rule, which became effective on September 8, 2006. The New M&A Rule, among other things, purports to require an offshore special purpose vehicle, or SPV, formed for the purpose
of listing the SPVs securities on an offshore securities exchange and controlled directly or indirectly by PRC companies or individuals, to obtain the approval of the CSRC prior to such offshore listing and trading. On September 21, 2006
the CSRC published on its official website procedures specifying documents and materials required to be submitted to it by SPVs seeking CSRC approval of their overseas listings. However, substantial uncertainty remains regarding the scope and
applicability of the New M&A Rule to overseas listings of offshore SPVs, which may continue to have an impact on us as a company newly listed overseas.

You should read the following in conjunction with our audited consolidated balance sheets for the years ended December 31, 2006 and 2007 and consolidated statements of income for the years ended December 2005, 2006 and 2007, in each
case together with the accompanying notes, all included elsewhere in this document. This discussion contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results could differ materially from those
projected in the forward-looking statements. In evaluating our business, you should carefully consider the information provided under the caption Item 3. Key InformationD. Risk Factors.

A. Operating Results

Overview

We are a leading, fully integrated, profitable biotechnology company focused on researching, developing, manufacturing and marketing biopharmaceutical
products primarily in China. Our recombinant, or genetically engineered, protein-based products and product candidates are designed to address large markets with significant unmet medical needs in nephrology, oncology, supportive cancer care,
inflammation and infectious diseases. We began operations in 1993. Our principal products are EPIAO (

LOGO) and TPIAO (

LOGO), and our legacy



56



---

products are Intefen (

LOGO) and Inleusin (

LOGO). Our newest internally developed product, TPIAO, was launched in January 2006 and has continued to gain market acceptance, ending the fiscal years 2006 and 2007 as our second largest revenue contributor,
accounting for 12.6% and 23.9% of our revenues for 2006 and 2007, respectively. Substantially all of our revenues and profits have been derived from these four existing products. We conduct our manufacturing and marketing activities through our
wholly owned subsidiary, Shenyang Sunshine.

We conduct our distribution and logistics activities through Beijing Sunshine and Liaoning
Sunshine. Liaoning Sunshine is a PRC limited liability company that is wholly owned by Dan Lou, our chairman. Beijing Sunshine is a PRC limited liability company that is 55% owned by Shenyang Keweier, a company owned by our employees and former
employees, and 45% owned by Dongmei Su, our chief technology officer. Liaoning Sunshine holds the licenses to the Tietai Iron Sucrose Supplement and to Baolijin. Beijing Sunshine and Liaoning Sunshine are VIEs whose results are consolidated in our
financial statements. For more details, see Note 1Principal activities, reorganization and basis of presentation to our consolidated financial statements.

For the three years ended December 31, 2005, 2006 and 2007, EPIAO generated approximately 83.1%, 77.3% and 67.3% of our total revenues,
respectively. The decrease was due to the launch in early 2006 of our TPIAO and its quick market acceptance since launch, which has rapidly become our second largest revenue contributor. According to data derived from IMS Health and internally,
EPIAO continued to be the market leader both in terms of revenues and sales volume, with market shares of 39.9% and 32.6%, respectively, for the year 2007. In 2007, we received from the SFDA licenses to produce and sell pre-filled syringe EPIAO in
2,000 IU, 3,000 IU, 4,000 IU, 10,000 IU strengths. We launched the new EPIAO formats in June 2007. The pre-filled syringe EPIAO has been an important addition to our product portfolio because of its increased safety, ease of use and the flexibility
to self-administer the medication at home.

In 2005, 2006 and 2007, approximately 8.3%, 4.8% and 2.8% of total revenues were generated by
sales of our legacy products Inleusin and Intefen (excluding export sales of Inleusin and Intefen). Beginning in 2004, we began to reduce focus on these products due to increased competition and pricing pressure.

We in-licensed exclusive distribution rights for a prescription iron sucrose supplement product, Tietai, which we began to market in August 2006. Also,
in August 2006, we in-licensed exclusive distribution rights for Baolijin, a recombinant human granulocyte colony-stimulating factor, a protein that stimulates production of white blood cells.

We are actively pursuing six product candidates in late-, mid- and early-stage clinical and pre-clinical development, including a high dosage EPIAO and
NuPIAO, our second-generation EPIAO. We also have development programs for a new indication for our TPIAO to treat ITP, a new version of IL-2 for the treatment of metastatic melanoma, a type of skin cancer, and metastatic renal cell carcinoma, a
type of kidney cancer, a HPV vaccine for the prevention of cervical cancer and an anti-TNF monoclonal antibody product candidate for treating rheumatoid arthritis, psoriasis, and potentially other inflammatory diseases.

We sell our products primarily in China. We also export a small portion of our products to certain developing countries, consisting of Egypt, Pakistan,
Thailand, Brazil, Mexico, Trinidad and Tobago, Guatemala and Columbia, where we have been approved to sell these products in compliance with local laws and regulations. While exports still constituted a small percentage at 3.8% of our total sales
for fiscal 2007, we intend to continue to develop exports in the future because of its growing opportunity.

Financing History

Shenyang Sunshine, our predecessor and now our operating subsidiary, was formed in 1993. Since our inception, we have focused our activities on research
and product development by funding our research and development projects and business expansion with cash generated from operations, debt financing, equity



57

issuances and various government grants. Our initial capital was contributed primarily by our majority shareholder, Shenyang Keweier, in the form of assets
and technology transfer. In 1995, we began marketing Intefen and initiated the research and development of TPIAO. In 1998, we began marketing EPIAO. From 1997 to 2004, we obtained government grants for a total of approximately RMB15 million and
RMB9.8 million to fund the manufacturing capacity expansion for EPIAO and TPIAO research and development, respectively. We expect that we will be able to fund our growing operations and capital expenditures with our working capital and the
proceeds from our initial public offering for the next 24 months.

Our Results of Operations

The following trends have historically affected, and we believe will continue to affect, our results of operations.

Continuing pricing pressure

The selling
prices of some of our products have declined over time due to increased pricing pressure from industry peers and the price control bidding process in China. For example, the average selling prices of our legacy products and lower dosage EPIAO
products have declined over time. We were able to maintain stable overall average selling prices for our higher dosage EPIAO products over the past few years. However, recent NDRC policy has caused us to lower prices on such products as well, which
had an adverse impact on the average selling price of our EPIAO products. Nonetheless, we remain focused on our strategy of growing sales for our high-dosage products and increasing sales volumes in order to maintain healthy margins for our EPIAO
products. In addition, the stable average prices of our exclusive TPIAO products, combined with their market acceptance since launch, have contributed to our revenue growth recently.

We believe our ability to continue to grow our revenues and remain profitable in the face of downward pricing pressure is dependent on the following
factors:

Reliance on EPIAO Sales. Throughout the three years ended December 31, 2007, our net revenue growth has been
primarily driven by increased sales of EPIAO. During this period, we have established a market leadership position in China with respect to EPIAO, which accounted for 67.3% of our total sales in 2007. In January 2006, we launched our new TPIAO
product which has become our second largest revenue contributor, with net sales revenue of RMB43.1 million, accounting for 23.9% of our overall sales for the year ended December 31, 2007. We will remain focused on promoting TPIAO products
to diversify our revenue sources.

Exclusivity. In some instances, we rely on exclusivity under administrative protection
periods to provide us with a competitive advantage. TPIAO for the treatment of chemotherapy-induced thrombocytopenia enjoys exclusivity under an administrative protection period through 2010.

Competitive bidding. In each province where we market our products, we participate in a government-sponsored competitive bidding process
every year or every few years, during which we and our competitors submit pricing and other product information to local pricing bureaus. The local pricing bureau will, based on the bidding price, quality and market share of the particular product
and the reputation of the bidder, select a limited number of products in each product category, which will be the only products of its category permitted for sale in the relevant province or local district.

Prescription regulations.As announced by the MOH, a new regulation on prescription drug management took effect on May 1, 2007, which
stipulates that doctors may only use the generic names of drugs in their prescriptions instead of brand names and that medical institutions offer patients the same type of drug from no more than two separate pharmaceutical companies. The purpose of
this legislation is to minimize the practice of doctors receiving kickbacks from pharmaceutical companies for prescribing higher priced, or even unneeded, drugs to patients. Given that we are the only EPO product on the market that has three
distinct indications and we



58



---

have established a strong brand name synonymous with quality and reliability, we remain optimistic that the regulation will have a net-positive effect on our
company.

Product mix. Our strategy is to alter our product mix to respond to pricing pressures by focusing our sales and
marketing resources on our more profitable products. For example, as our legacy products became less profitable, our sales and marketing force focused on improving the sales volumes of our higher dosage forms of EPIAO, such as our 4,000 IU/vial and
10,000 IU/vial EPIAO formulations. We also shift our product mix through the introduction of new products, such as our proprietary new drug, TPIAO, our newly approved pre-filled syringe EPIAO and our in-licensed iron sucrose supplement.In addition, we began out-sourcing the marketing efforts of our legacy products, Intefen and Inleusin, to distributors in 2005, thereby improving our overall product mix and sales force efficiency.

Export sales. In addition to our domestic sales, we also export certain of our products to certain developing countries, consisting of Egypt,
Pakistan, Thailand, Brazil, Mexico, Trinidad and Tobago, Guatemala and Columbia, where we have been approved to sell these products in compliance with local laws and regulations. We initiated our export business in 2003 to a country in the Middle
East through an export company in China. Increasingly in subsequent years, we have worked with local agents in countries in the Middle East, South America and in Southeast Asia. Our export sales primarily consist of sales of EPIAO, Intefen and
Inleusin, in the form of raw material in bulk format as concentrated solutions or as finished products. Export sales accounted for 4.9%, 4.6% and 3.8% of our total revenues for the years ended December 31, 2005, 2006 and 2007, respectively.
While export sales accounted for a small percentage of our total revenues in past periods, we believe, in the long term, growth in export sales may assist us in offsetting pricing pressures in our domestic market.

Different sales channels for different products. As of December 31, 2007, our internal sales and marketing force consisted of 194
marketing and sales representatives focused on hospitals, clinics and dialysis centers in 30 Chinese provinces and major cities including the municipalities of Beijing and Shanghai and the city of Guangzhou. In addition, as of the end of April 2008,
our sales force increased to 225 as a result of our strategy to create a dedicated sales team which focuses specifically on the area of oncology to supplement our existing focus in nephrology. As pricing pressures drive down the average selling
price of a product, we may focus our internal sales force on other, more profitable products. For example, since 2004 we have devoted a decreasing amount of resources to the marketing of our two legacy products, Intefen and Inleusin, which had
historically been significant contributors to our total revenues, as we strategically realigned our internal focus on EPIAO and TPIAO. At the same time, we began outsourcing the sales efforts for the two legacy products to distributors who manage
their own sales forces while we reimburse their related costs of selling based on pre-determined percentages of sales and timeliness of collection.

Taxes and incentives

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

Under
the current PRC laws, Shenyang Sunshine is subject to EIT and value-added tax, or VAT.The PRC government has provided various incentives to high technology companies in order to encourage development of the high technology industry.
Such incentives include reduced tax rates and other measures. For example, as a high technology company operating in an approved economic-technological development area, Shenyang Sunshine was entitled to an EIT rate of 15% in 2007, compared to the
standard EIT rate of 33% applicable to most domestically owned PRC companies. As a foreign-invested advanced technology enterprise certified by the relevant Chinese authorities, Shenyang Sunshine was entitled to a further reduced EIT
rate of 10% for the year ended December 31, 2005. The reduced EIT rate expired after the year ended December 31, 2005, and Shenyang Sunshines EIT was 15% for the years ended December 31, 2006 and 2007.



59



---

On March 16, 2007, the EIT Law was enacted. Under the EIT Law, effective January 1, 2008, China
adopted a uniform tax rate of 25% for all enterprises (including foreign-invested enterprises) and revoked the current tax exemption, reduction and preferential treatments applicable to foreign-invested enterprises. However, there is a transition
period for enterprises, whether foreign-invested or domestic, that were receiving preferential tax treatments granted by relevant tax authorities at the time the EIT Law became effective. Enterprises that are subject to an EIT rate lower than 25%
may continue to enjoy the lower rate and gradually transition to the new tax rate within five years after the effective date of the EIT Law. Enterprises that are currently entitled to exemptions or reductions from the standard income tax rate for a
fixed term may continue to enjoy such treatment until the fixed term expires. Preferential tax treatments will continue to be granted to industries and projects that are strongly supported and encouraged by the state, and enterprises otherwise
classified as such encouraged high-tech enterprises will be entitled to a 15% EIT rate. On April 14, 2008, the Measures were promulgated and became retroactively effective from January 1, 2008. Under the Measures, the term
high-tech enterprise is defined as a resident enterprise that has been registered in the PRC (excluding Hong Kong, Macao or Taiwan) for more than one year, conducts business in the new and high-tech fields encouraged by government as
listed in an appendix to the Measures, continuously undertakes research and development and technology conversion, and relies on self-owned intellectual property rights as the basis of its business operation. Such new and high-tech enterprises may
apply for tax incentives. There is no assurance that Shenyang Sunshine will qualify as a new and high-tech enterprise under the Measures.

The EIT Law also provides that enterprises established outside of China whose de facto management bodies are located in China are considered resident enterprises and will generally be subject to the uniform 25% EIT
rate as to their global income, including income they receive from their subsidiaries. Pursuant to the Implementation Rules, the term de facto management bodies is defined as bodies that undertake overall management and control of the
production, operation, human resource, finance, property and similar activities of the enterprise in material respects. Despite the Implementation Rules, it is still not entirely clear under what situations an enterprises de facto
management body is considered to be located in China. However, all of our management is currently based in China, and will likely remain in China for the foreseeable future. In addition, although the EIT Law provides that dividend income
between qualified resident enterprises is exempted income, it is unclear what is considered a qualified 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 we may pay, if any, to our shareholders and ADS holders. Furthermore, unlike the Income Tax Law for Enterprises with Foreign Investment and Foreign
Enterprise (superseded by the EIT Law), which specifically exempts withholding tax on any dividends payable to non-PRC investors, the EIT Law provides that an income tax rate of 10% will normally be applicable to dividends payable to non-PRC
investors which are derived from sources within China, although such income tax may be exempted or reduced by the State Council. We are a Cayman Islands holding company and substantially all of our income may come from dividends we receive from our
operating subsidiaries located in China. If we declare dividends from such income, it is not clear whether it will be deemed to be derived from sources within China under the EIT Law and be subject to the 10% income tax. If we are required under the
EIT Law to withhold income tax on our dividends payable to our non-PRC shareholders and ADS holders, your investment in us may be materially and adversely affected.

As of December 31, 2007, we recorded total deferred tax assets of approximately RMB4.2 million (US$0.6 million). Reduction or elimination of the financial subsidies or preferential tax treatments we
currently enjoy or imposition of additional taxes on us or our subsidiaries in China may have a material adverse effect on our income tax expense and net income. See Item 3. Key InformationD. Risk FactorsRisks related to our
companyOur business benefits from certain government incentives. Expiration of, or changes to, these incentives could have a material adverse effect on our operating results.

VAT

Our revenues are recorded net of VAT. VAT is charged based on the selling price of our products at a general rate of 17%. In China, pharmaceutical companies are accustomed to having the market sales data referenced to the gross revenues,
inclusive of the VAT. For example, the data quoted by IMS Health throughout this document are quoted on gross revenues.

Customer and supplier
concentration

Sales to our top ten distributors accounted for approximately 50.0%, 53.6% and 53.0% of our total revenues for the
years ended December 31, 2005, 2006 and 2007, respectively.

Our top five suppliers and the single largest supplier as percentages of
our overall cost of revenues were 16.8% and 5.0%, respectively, for the year ended December 31, 2007. We primarily source our raw materials from a variety of international suppliers through their local distributors. We do not anticipate any
significant fluctuations in price or any significant disruptions in the supply of our raw materials in the near future. We believe that generally our switching cost for our major suppliers is not high because alternative suppliers are readily
available.

Financial Overview

Revenues

Revenues consist of the invoiced value of goods sold, net of VAT, trade discounts and allowances, and, in very rare circumstances,
discretionary sales returns. In the PRC, VAT on the invoice amount is collected on behalf of tax authorities in respect of the sales of goods. Revenue is stated net of VAT. VAT collected from customers is set off by VAT paid for purchases, with the
net amount recorded as a liability in the consolidated balance sheet until it is paid to the authorities.

We sell our products primarily
to distributors, who resell them to healthcare providers, including hospitals and dialysis centers. With respect to our principal products, EPIAO and TPIAO, we rely on our own sales force to promote them to the hospitals and other customers. Because
of PRC regulations governing the distribution of pharmaceuticals by manufacturers, we direct our customers to purchase our products from designated distributors. We generally sell our products to these distributors at a discount of approximately 8%
off the wholesale prices to healthcare providers such as hospitals and dialysis centers. With respect to legacy products, Intefen and Inleusin, we primarily rely on distributors to market, as well as sell, our products with their own sales force. We
reimburse the related costs of these distributors sales efforts in the form of a negotiated discount.

We generally recognize
revenues at the time our products are delivered and the customers take ownership and assume risk of loss, collection of the relevant receivable is probable, persuasive evidence of an arrangement exists and the sales price is fixed or determinable.
We are a party to binding purchase agreements with our distributors or with our hospital customers each time we make a sale of our products. Under these purchase agreements, our distributors or hospital customers agree to pay a non-refundable, fixed
amount of money per unit of our products over a period of time. Our distributors take ownership of our products when either they themselves or the hospitals designated by them under contracts accept our products.

Allowance for doubtful accounts

We maintain
allowances for doubtful accounts for estimated losses resulting from the failure of our customers to make required payments. We review the accounts receivable on a periodic basis and make general and specific allowances when there is doubt as to the
collectibility of individual balances. In evaluating the collectibility of our customers balances, we consider many factors, including the aging of the receivables, the customers past payment history and current credit-worthiness. We are
subject to stringent requirements



61



---

mandated by scrutiny of the local Chinese tax authorities on write-offs of bad debts. For example, bad debts must be aged over three years and sufficient
evidence must be provided to prove customers inability to make payments. As a result, this creates a substantial time lag between the time when our bad debt provision is made and the removal of such doubtful debt from our books. We made an
allowance for doubtful accounts of RMB386,000 (US$52,916) for the year ended December 31, 2007. As of December 31, 2006 and 2007, there were no material amounts of receivables outstanding for more than one year that were not reserved.

Cost of revenues

Our cost of
revenues includes costs of raw materials, packaging, labor costs and manufacturing overhead. Our manufacturing overhead is primarily comprised of factory staff costs, allocated utilities and depreciation of our production facilities. We believe the
relatively low cost of labor in the PRC provides us with a significant competitive advantage compared to international competitors that are not producing products in the PRC. We expect that, after we commence operations in our new manufacturing
facilities, depreciation charges will increase on a per unit basis in early years before the full deployment of the capacity of our new manufacturing facilities.

Operating expenses

Our operating expenses include research and development expenses, sales, marketing and
distribution expenses and general and administrative expenses. The key components of our operating expenses are described below.

Research and development expenses. Our research and development expenses are related to activities such as preclinical studies and clinical trials and consist primarily of:



| |  |  | Direct and allocated salaries and related expenses for research and development personnel;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | Fees paid to consultants and clinical research organizations in conjunction with their monitoring our clinical trials and acquiring and evaluating data in
conjunction with our clinical trials;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Direct cost of materials used in research and development;
| | - |  | ----------------------------------------------------------



| |  |  | Direct cost of equipment that lacks an alternative future use;
| | - |  | --------------------------------------------------------------



| |  |  | Fees paid to independent research organizations in conjunction with preclinical animal studies;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | Allocated depreciation of research equipment and laboratory facilities;
| | - |  | -----------------------------------------------------------------------



| |  |  | Manufacturing costs of our clinical trial supply quantities for our product candidates;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | Costs associated with other clinical development such as seminar hosting and process optimization; and
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | Costs for seeking EMEA approval so that we may enter the European market for biosimilar products which are new versions of biopharmaceutical products whose patents
have expired.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



62



---

In accordance with U.S. GAAP, we expense both internal and external research and development costs as
incurred, other than laboratory equipment with alternative future uses, which we capitalize. Due to the fact that the tax incentive for incurring research and development costs in China is minimal, we do not track our internal research and
development costs by program in detail and cannot state precisely the costs incurred for each of our research and development programs in the past. However, the following table shows our estimate of the total costs that have been incurred for our
two principal products, EPIAO and TPIAO, and others during each of the years indicated.



|             |  |                         |  |       |  |        |  |

|             |  |                         |  |       |  |        |  |      

The table above contains research and development costs attributable to the ongoing clinical
trials for expanded indications of our marketed products, as well as preclinical and clinical trials for our product candidates.

Sales,
marketing and distribution expenses. Our sales, marketing and distribution expenses primarily consist of salaries, employee benefits, bonuses and related expenses for our sales and marketing staff. They also include the direct costs
attributable to our sales and marketing activities, such as conferences and seminar hosting and attendance, travel, entertainment and advertising expenses. We expect our sales, marketing and distribution expenses to increase in absolute dollar
amounts in the future as we continue to expand the portfolio of our products. In future periods, we will seek to maintain a relatively stable or moderate improvement in terms of percentage of the sales, marketing and distribution expenses relative
to our total revenues.

General and administrative expenses. Our general and administrative expenses primarily consist of
salaries and employee benefits, including share-based compensation for our administrative staff, as well as depreciation charges of office premises and equipment. We expect our general and administrative expenses to increase in absolute monetary
amounts in line with our continued growth.

Other income/(expense), net

We record our other income net of interest expense and foreign currency exchange losses. Our other income principally comprises interest income, grant
income and various non-recurring items that are not part of our normal operating activities.

Government grants

At various stages during the period from 1997 to 2004, we obtained a total of approximately RMB15 million to fund capacity expansion at our Shenyang
manufacturing facilities to accommodate production of clinical quantities of EPIAO and RMB10 million to fund our research and development efforts relating to our TPIAO program. We do not expect to receive significant additional government grant
income for the near future.

Grants for the acquisition of property, plant and equipment are reflected as deferred income on our
consolidated balance sheet when there is reasonable assurance they will be received and the deferred income is amortized to the statement of income over the useful life of the acquired asset. Grants that compensate us for expenses incurred are
recognized as other income in our consolidated statements of income upon the later of award of the grant or in the same period in which the related expenses are incurred.

Consolidation of variable interest entities

Variable interest entities, or VIEs, are those entities in which a company, through contractual and/or other arrangements, bears the risks of, and enjoys
the rewards normally associated with ownership of the entities, and therefore the company is the primary beneficiary of these entities. We have adopted FIN 46R, which requires certain VIEs to be consolidated by the primary beneficiary of the VIE if
equity investors in the VIE do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without subordinated financial support from other parties. The results
of VIEs are consolidated in a companys financial statements from the date the company became the primary beneficiary of the VIE.

The
following is a summary of our VIEs:

Beijing Sunshine is a domestic limited liability company which was incorporated in 2000 under PRC law.
Beijing Sunshine is primarily engaged in the distribution of products manufactured by Shenyang Sunshine. Prior to our reorganization in anticipation of our initial public offering in February 2007, Shenyang Sunshine held a 45% equity interest in
Beijing Sunshine while Shenyang Sunshines majority shareholder prior to the reorganization, Shenyang Keweier, held the remaining 55% equity interest in Beijing Sunshine. The registered capital of Beijing Sunshine is RMB1,010,000. Liaoning
Sunshine is a domestic limited liability company incorporated in 2000 under PRC law. Liaoning Sunshine is primarily engaged in the distribution of products manufactured by Shenyang Sunshine and in-licensed products. Prior to our reorganization in
anticipation of our initial public offering, Shenyang Sunshine held a 90% equity interest in Liaoning Sunshine, and Shenyang Keweier held the remaining 10% equity interest in Liaoning Sunshine. The registered capital of Liaoning Sunshine is RMB15.0
million.

In connection with our corporate reorganization, we transferred our 45% equity interest in Beijing Sunshine to Ms. Dongmei
Su, our chief technology officer, in October 2006 and our 90% equity interest in Liaoning Sunshine to Mr. Dan Lou, our chairman, in November 2006. Upon the consummation of these transfers, we also entered into a series of contractual
arrangements with Beijing Sunshine and Liaoning Sunshine, through which we bear economic risks with respect to, and derive economic benefits from, their operations. For more details, see Item 4. Information on the CompanyC.
Organizational Structure.

The total equity investment at risk is not sufficient to permit either Beijing Sunshine or Liaoning
Sunshine to finance its activities without additional subordinated financial support provided by Shenyang Sunshine. Shenyang Sunshine finances each of Beijing Sunshine and Liaoning Sunshine in the form of subordinated trade payables arising from the
sales of products from Shenyang Sunshine to Beijing Sunshine or Liaoning Sunshine.

As variable interests in each of Beijing Sunshine and
Liaoning Sunshine are predominately held by Shenyang Sunshine, Shenyang Sunshine is deemed to be the primary beneficiary of each of Beijing Sunshine and Liaoning Sunshine under FIN 46R. Accordingly, the financial statements of Beijing Sunshine and
Liaoning Sunshine are consolidated in Shenyang Sunshines financial statements from the respective dates Shenyang Sunshine became involved with each of Beijing Sunshine and Liaoning Sunshine.

The transfers of our equity interest in Beijing Sunshine and Liaoning Sunshine did not change our requirement to consolidate Beijing Sunshine and
Liaoning Sunshine under FIN 46R.

Critical Accounting Policies and Estimates

The discussion and analysis of our operating results and financial condition are primarily based on our audited financial statements of our Group, which
have been prepared in accordance with U.S. GAAP. Our operating results and consolidated financial condition are sensitive to accounting methods, assumptions and estimates that underlie the preparation of our financial statements. We base our
assumptions and estimates on historical experience and on various other assumptions that we believe to be reasonable and which form the basis



64



---

for making judgments about matters that are not readily apparent from other sources. Our management evaluates these estimates on an ongoing basis. Actual
results may differ from these estimates as facts, circumstances and conditions change or as a result of different assumptions.

Our
management considers the following factors in reviewing our financial statements:



| |  |  | the selection of critical accounting policies; and
| | - |  | --------------------------------------------------



| |  |  | the judgments and other uncertainties affecting the application of those critical accounting policies.
| | - |  | ------------------------------------------------------------------------------------------------------

The selection of critical accounting policies, the judgments and other uncertainties affecting application of those policies and the sensitivity of
reported results to changes in conditions and assumptions are factors to be considered when reviewing our financial statements. Our principal accounting policies are set forth in detail in Note 2 to our consolidated financial statements included
elsewhere in this annual report. We believe the following critical accounting policies involve the most significant judgments and estimates used in the preparation of our financial statements.

Revenue recognition

Sales of our
pharmaceutical products represent the invoiced value of goods sold, net of VAT, trade discounts and allowances, and, in very rare circumstances, sales returns. Revenues from these sales transactions are generally recognized upon delivery, which is
considered to have occurred when the customer has taken risks and awards associated with the ownership of delivered products.

For the two
legacy products Intefen and Inleusin which we market using third parties sales efforts and reimburse expenses incurred by the agency distributors based on a predetermined percentage of sales and timeliness of collection, we account for revenues from
this type of sales channel in accordance with EITF Issue No. 01-9. Under EITF Issue No. 01-9, our cost reimbursement offered to distributors is classified as a reduction in sales revenue. Based on the terms and conditions agreed with the
distributors, we accrued and recorded the reimbursements of expenses to the distributors as reduction in revenue, which reduced net sales by RMB1.7 million, RMB1.4 million and RMB2.1 million (US$0.3 million) in the years ended December 31,
2005, 2006 and 2007, respectively.

Research and development costs

We expense research and development costs except for equipment that has alternative future uses in accordance with Statement of Financial Accounting
Standards (SFAS) No. 2 Accounting for Research and Development Costs. We critically identify any research and development activities that could be objectively measured and recognized and are aimed at the discovery of new products,
indications, or betterment of processes. We capitalize the costs of materials and equipment that have alternative uses and amortize them over their useful life. Elements of research and development costs may include direct materials, direct labor
and overhead allocation including other related personnel engaged in research and development activities. Expenses relating to new products are charged to the statement of income until such time that we obtain the new medicine certificate. The costs
of research and development services such as pre-clinical tests outsourced or contract consulting services for upgrading our facilities are also included. The determination of alternative use requires judgment about the application of developed
processes and know-how as well as market acceptance of related products. Different judgments regarding alternative uses could result in a change in the timing and amount of costs capitalized as materials and equipment.

Share-based compensation expenses

Effective
from January 1, 2006, we adopted SFAS No. 123 (revised in 2004), Share-Based Payment, or SFAS 123R. Share-based payment transactions within the scope of SFAS 123R include grants of stock options,



65



---

restricted stock, performance-based awards and stock appreciation rights, as well as purchases under employee share purchase plans. These transactions are
viewed generally as non-cash compensation awarded to employees, directors and advisors in lieu of cash compensation.

In June 2006, our
then principal shareholder committed to grant restricted shares to one of our directors and one of our senior executives. For purposes of recording compensation expense, we treated this grant as if it was made by us, which would have vested upon the
earlier of (i) December 1, 2007 or (ii) on the date of our initial public offering. In accordance with SFAS 123R, since the stock awards contained vesting and exercisability conditions other than those based on service, performance or
market criteria, they were treated as liability-classified awards initially recorded at their estimated fair value as of the grant date and subject to re-measurement at each future financial reporting date through the settlement date. The stock
awards were subsequently modified and settled in October 2006 with a total number of 312,504 fully vested ordinary shares granted to the two individuals. The stock awards ceased to be liability-classified and were reclassified as equity upon
settlement. The fair value of the modified awards as of the settlement date of approximately RMB1,877,000 was charged to the consolidated statement of income for the year ended December 31, 2006 as the total adjusted share-based compensation
expense for the stock awards. The fair value of the modified awards as of the settlement date was estimated based on the price of the sale in October 2006 of our ordinary shares by our former shareholder to third-party investors.

In August 2006, we granted 15,000 shares to a senior executive with a one year vesting period. The effect of such award on our financial results is
immaterial. In October 2006, we granted several directors and employees options to purchase a total of 1,060,000 of our ordinary shares at an exercise price of US$1.60 per ordinary share, which primarily vest on a proportionate basis over a
three-year vesting period. In addition, in July 2007, we granted a senior executive options to purchase a total of 100,000 of our ordinary shares at an exercise price of US$1.60 per share, which become exercisable on May 31, 2008 and expire on
June 1, 2010. The fair value of each option award is estimated on the date of grant using the Black-Scholes pricing model based on various assumptions. For more details, see Note 18 to our consolidated financial statements included elsewhere in
this annual report.

Estimated useful lives and impairment of long-lived assets

We make estimates of the useful lives of property, plant and equipment with finite useful lives, in order to determine the amount of depreciation expense
to be recorded during any reporting period. Our total depreciation expenses in the years ended December 31, 2005, 2006 and 2007 were RMB7.5 million, RMB5.5 million and RMB4.9 million (US$0.7 million), respectively. The useful lives are
estimated at the time the assets are acquired and are based on historical experience with similar assets as well as anticipated technological or other changes. If technological changes were to occur more rapidly than anticipated or in a different
form than anticipated, the useful lives assigned to these assets may need to be shortened, resulting in the recognition of increased depreciation expense in future periods.

Long-lived assets, including property, plant and equipment assets with finite useful lives, are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of long-lived assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash
flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value
of the asset. Fair value is measured by the assets discounted cash flows or market value, if readily determinable. There have been no impairment charges recognized for the three years ended December 31, 2007.

Allowance for doubtful accounts

We evaluate
the recoverability of our account receivables based on a combination of factors. We regularly analyze our significant customer accounts, and, when we become aware of a specific customers inability to meet



66



---

its financial obligations to us, such as in the case of bankruptcy filings or deterioration in the customers operating results or financial position,
we record a specific reserve for bad debt to reduce the related receivable to the amount we reasonably believe is collectible. We also record reserves for bad debt for all other customers based on a variety of factors, including the length of time
the receivables are past due, the financial health of the customer and historical experience. If circumstances related to specific customers change, our estimates of the recoverability of receivables could be further adjusted. In the event that our
trade receivables become uncollectible, we record additional adjustments to receivables to reflect the amounts at net realizable value. The accounting effect of this entry would be a charge to income. We believe that the current charges to income
are sufficient to reflect the recoverability of our accounts receivable.

Inventories and allowance for obsolescence

We state all inventories at the lower of cost or market value, determined using the weighted average cost method. We provide inventory allowances when
conditions indicate that the selling price could be less than cost due to physical deterioration, usage, obsolescence and reductions in estimated future demand. We balance the need to maintain strategic inventory levels with the risk of obsolescence
due to varying customer demand levels and changing technology, although this rarely happens. Unfavorable changes in market conditions may result in additional inventory reserves that could adversely impact our gross margins. Conversely, favorable
changes in demand could result in higher gross margins when we sell products.

Year ended December 31, 2006 compared with year ended December 31, 2007

Revenues. Our revenues increased by 41.0%, from RMB127.8 million in 2006 to RMB180.2 million (US$24.7 million) in 2007. This increase was
primarily attributable to the rapid market adoption of our TPIAO products, which generated revenues of RMB43.1 million (US$5.9 million) in 2007, compared to RMB16.1 million in 2006. TPIAO was our second largest revenue contributor in 2007,
accounting for 23.9% of total revenues in the year. The increase was also attributable to greater revenues from our leading EPIAO products, which increased by 22.7% from RMB98.8 million in 2006 to RMB121.2 million (US$16.6 million) in 2007,
primarily due to the expansion of our oncology sales force and concurrent increase in market share.

Cost of revenues. Our
costs of revenues were RMB11.6 million and RMB17.4 million (US$2.4 million) for the years ended December 31, 2006 and 2007, respectively. The increase was primarily due to the increase in sales volume and a one-time cost of RMB1.0 million
(US$0.1 million) due to forfeiture of deposits as we did not meet the sales volume target for Tietai Iron Sucrose Supplement.

Operating
expenses. Our total operating expenses increased by 43.4% from RMB79.6 million in 2006 to RMB114.2 million (US$15.7 million) in 2007. The increase was primarily due to an increase in sales, marketing and distribution expenses.



| |  |  | Research and development expenses.Our research and development expenses increased 90.7% to RMB11.6 million (US$1.6 million) for 2007 from RMB6.1 million for
2006. The increase was mainly attributable to the research and development expenses associated with TPIAOs phase IV post-marketing clinical tests, the development of our new EPIAO product candidates and the continued development of other new
products.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Sales, marketing and distribution expenses. Our sales, marketing and distribution expenses increased 37.4% to RMB84.2 million (US$11.5 million) in 2007
from RMB61.3 million in 2006. The increase was primarily attributable to increased marketing activities and higher staff costs and bonuses as a result of an increase in headcount. Sales, marketing and distribution expenses as a percentage of
revenues decreased from 47.9% in 2006 to 46.7% in 2007.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | General and administrative expenses. Our general and administrative expenses increased 49.8% from RMB12.3 million in 2006 to RMB18.4 million (US$2.5
million) in 2007. The increase was primarily attributable to the increase in staff costs and bonuses as a result of an increase in headcount. General and administrative expenses remained stable at around 10%.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Other income/(expense), net.We had net other income of RMB36.5 million (US$5.0 million) in 2007 compared to net other expense of RMB0.9 million
in 2006, primarily due to the interest income on the net proceeds we received from our initial public offering in February 2007 and a decrease in interest expense as we fully repaid our borrowings in 2007.

Income before income tax expense and minority interests. As a result of the foregoing, our income before income tax expense and minority
interests increased 138.3% from RMB35.7 million in 2006 to RMB85.0 million (US$11.7 million) in 2007.

Income tax
expense. Our income tax expense decreased 34.5%, from RMB5.2 million in 2006 to RMB3.4 million (US$0.5 million) in 2007, and our effective tax rate was 4.0% for 2007 as compared to 14.6% for 2006, primarily attributable to a tax
rebate of RMB2.7 million (US$0.4 million) from the reinvestment of retained earnings in a subsidiary and the interest income on the net proceeds from our initial public offering which was paid to our company incorporated in the Cayman Islands and
not subject to tax.

Net income. As a result of the foregoing, our net income increased 167.8%, from RMB30.5 million in
2006 to RMB81.6 million (US$11.2 million) in 2007.

Year ended December 31, 2005 compared with year ended December 31, 2006

Revenues. Our revenues increased by 25.3%, from RMB102.0 million in 2005 to RMB127.8 million in 2006. This increase was primarily
attributable to the rapid market adoption of our TPIAO products, which generated revenues of RMB16.1 million in 2006, compared to RMB2.8 million in 2005. TPIAO was our second largest revenue contributor in 2006, accounting for 12.6% of total
revenues in the year. The increase was also attributable to greater revenues from our leading EPIAO products, which increased by 16.5% from RMB84.8 million in 2005 to RMB98.8 million in 2006. Our revenue in 2006 were negatively affected by a
government sponsored anti-corruption campaign, under which certain hospitals denied access to sales representatives from pharmaceutical companies because the hospitals wanted to avoid the perception of corruption, which in turn temporarily limited
our ability to expand into new hospitals in 2006.

Cost of revenues. Our costs of revenues were RMB15.5 million and
RMB11.6 million for the years ended December 31, 2005 and 2006. The cost of revenues as a percentage of revenues was higher at 15.2% in 2005, as compared to 9.1% in 2006, primarily caused by costs reduction in fiscal year 2006 primarily
attributable to a decrease in depreciation charges, reduced needs for provisions and charges such as inventory write-offs and amortization of intangibles and an increased production yield for EPIAO in 2006.

Operating expenses. Our total operating expenses increased by 20.0% from RMB66.4 million in 2005 to RMB79.6 million in 2006. The
increase was primarily due to an increase in sales, marketing and distribution expenses.



| |  |  | Research and development expenses.Our research and development expenses increased 90.9% to RMB6.1 million for 2006 from RMB3.2 million for 2005. The
increase was mainly attributable to research and development expenses associated with TPIAOs phase IV post-marketing clinical tests and the development of our EPIAO pipeline products. The increase was also related to a one-time licensing fee
for the licensing and co-development of anti-TNF alpha monoclonal antibody therapeutics with Epitomics Inc., and for continued development of other pipeline products.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Sales, marketing and distribution expenses. Our sales, marketing and distribution expenses increased 24.5% to RMB61.3 million in 2006 from RMB49.2
million in 2005. The increase was primarily attributable to higher staff costs and bonuses as well as the increase in marketing and promotion costs for our TPIAO and higher sales activities in general. Sales, marketing and distribution expenses as a
percentage of revenues remained stable at around 48%.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | General and administrative expenses. Our general and administrative expenses decreased 12.1% from RMB14.0 million in 2005 to RMB12.3 million in 2006.
The decrease was primarily attributable to the reduced requirement for bad debt provision and depreciation, partially offset by an increase in stock-based compensation charge. General and administrative expenses as a percentage of revenues decreased
from 13.7% in 2005 to 9.6% in 2006.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Other expense, net. Net other expense decreased 65.6% from RMB2.5
million in 2005 to RMB0.9 million in 2006. The decrease was primarily due to lower interest expenses resulting from reduced average bank borrowings in 2006.

Income before income tax expense and minority interests. As a result of the foregoing, our income before income tax expense and minority interests increased 101.9% from RMB17.7 million in 2005 to
RMB35.7 million in 2006.

Income tax expense. Our income tax expense increased 196.1%, from RMB1.8 million in 2005 to
RMB5.2 million in 2006, and our effective tax rate was 10.0% for 2005 as compared to 14.6% for 2006, primarily attributable to the effects of non-deductible share-based compensation expenses in 2006 and an increase in applicable tax rate for
our major operating subsidiary from 10% in 2005 to 15% in 2006 due to the expiration of a tax holiday.

Net income. As a result of the foregoing, our net income increased 89.9%, from
RMB16.1 million in 2005 to RMB30.5 million for 2006.

Net cash provided by operating activities

Our net cash provided by operating activities was RMB68.8 million (US$9.4 million) in 2007 compared to RMB37.0 million in 2006. The increase of RMB31.8
million in cash provided by operating activities in 2007 from 2006 reflects an increase in net income of RMB51.0 million, partially offset by a RMB14.8 million increase in accounts receivable primarily due to the increase in sales volume.

Our net cash provided by operating activities was RMB37.0 million in 2006 compared to RMB24.8 million in 2005. The increase of RMB12.2
million in cash provided by operating activities in 2006 from 2005 reflects an increase in net income of RMB14.4 million, a non-cash share-based compensation charge, and one time lease prepayment made in 2005 but non-recurring in 2006, which were
partially offset by increased inventories and receivables.

Net cash provided by / (used in) investing activities

Our net cash used in investing activities was RMB36.5 million (US$5.0 million) in 2007, compared to net cash provided by investing activities of RMB17.0
million in 2006. The cash outlay in investing activities in 2007 consisted primarily of RMB11.7 million (US$1.6 million) for purchases of property, plant and equipment related to the upgrade of existing facilities and other fixed assets and
leasehold improvements, RMB5.6 million (US$0.8 million) in deposits for the acquisition of property, plant and equipment related to construction of new manufacturing facilities, and RMB15.7 million (US$2.2 million) for purchases of
available-for-sale securities

(primarily in long-term corporate bonds). The net cash inflow from investing activities in 2006 resulted primarily from the repayment of a loan advanced to
shareholder Shenyang Keweier.

Our net cash used in investing activities was RMB9.2 million in 2005, compared to net cash provided by
investing activities of RMB17.0 million in 2006. The cash outflow in investing activities in 2005 was primarily due to a RMB9.2 million payment for renovation of our office in Beijing and the purchase of equipment.

Our capital expenditure amounted to RMB9.2 million, RMB2.7 million and RMB17.3 million (US$2.4 million) in the years ended December 31, 2005, 2006
and 2007, respectively. For more details, see Capital Expenditures below.

Net cash provided by / (used in) financing activities

Net cash provided by financing activities was RMB801.7 million (US$109.9 million) in 2007, compared to RMB54.5 million used in
financing activities in 2006 primarily due to the net proceeds we received from our initial public offering in 2007.

Net cash used in
financing activities was RMB10.0 million in 2005, compared to RMB54.5 million used in financing activities in 2006 due to continued efforts of paying down our bank loans. The net repaid bank borrowings were RMB10.0 million and RMB49.0 million
in 2005 and 2006, respectively.

We believe that our current cash and anticipated cash flow from operations will be sufficient to meet our
anticipated cash needs, including planned capital expenditures for upgrading existing facilities and building new manufacturing facilities in Shenyang, other working capital needs for investing in research and development and increasing sales and
marketing efforts at least for the next two years.

Our indebtedness as of the dates indicated was as follows:

We do not expect to pay dividends in the near future as we plan to use our resources for our
growth. However, should we decide to pay dividends, our wholly-owned subsidiarys ability to pay dividends to us is subject to various restrictions, including legal restriction in the PRC, which permits payment of dividends only out of net
income determined in accordance with PRC accounting standards and regulations. In addition, under PRC law, our subsidiary is required to set aside 10% of its net income as reserve funds, until such reserves have reached at least 50% of its
respective registered capital. These reserves are not distributable as cash dividends to us for use by us to satisfy our obligations, such as debt incurred at the holding company level. Such dividends may also be subject to income tax in the PRC
under the new EIT Law as discussed above under Our Results of OperationsTaxes and Incentives.

Capital Expenditures

The following sets forth our total capital expenditures for the periods indicated.

Historically, most of our capital expenditures were incurred for purchases of production and
office equipment, research laboratory, upgrade for our plant and office renovation. In the year ended December 31, 2007, our capital expenditure of RMB17.3 million (US$2.4 million) related primarily to upgrading of existing facilities,
construction of new manufacturing facilities, office renovation, and purchases of office equipment and other fixed assets.

In the
year ended December 31, 2006, our capital expenditures of RMB2.7 million related primarily to purchases of office and production equipment for our TPIAO and EPIAO products and, to a lesser extent, purchase of automobiles.

Capital expenditures in 2005 totaled RMB9.2 million, approximately half of which was related to equipment acquired for the production of TPIAO, with the
remaining attributable to general office equipment, final payment and renovation cost for our Beijing office and purchases of automobiles.

Our future capital requirements include, but are not limited to, upgrading our existing facilities for our research and development and production to meet EMEA standards and to build new facilities. Although we are not obligated to meet any
absolute minimum dollar spending requirements, our future capital requirements will depend on many factors, including the scope and progress made in building our new manufacturing facilities in the next two years. The major component of our planned
capital expenditures for 2008 is construction of the new manufacturing facilities.

We expect to fund our capital expenditure needs with a
combination of cash generated from operating activities and proceeds from our initial public offering in February 2007 without much need for debt financing. Therefore, we believe that the anticipated higher depreciation charges related to our
ongoing and planned facility expansion could be offset to a certain extent by the expected reduction in interest costs.

Recent Issued Accounting
Standards

SFAS No. 159

In
February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities. Including an Amendment of FASB Statement No. 115 (SFAS No. 159). SFAS No. 159 permits an entity to elect fair
value as the initial and subsequent measurement attribute for many financial assets and liabilities. Entities electing the fair value option would be required to recognize changes in fair value in earnings. Entities electing the fair value option
are required to distinguish, on the face of the balance sheet, the fair value of assets and liabilities for which the fair value option has been elected and similar assets and liabilities measured using another measurement attribute. The Group is
required to adopt SFAS No. 159 beginning on January 1, 2008. The adjustment to reflect the difference between the fair value and the carrying amount would be accounted for a cumulative-effect adjustment to retained earnings as of the date
of initial adoption. We have determined not to adopt the fair value option for existing eligible items as of January 1, 2008.

SFAS No. 160

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statementsan Amendment of
ARB No. 51. SFAS No. 160 establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. Among other requirements, the new standard will result in the presentation
of what are currently considered minority interests to be classified as equity. The guidance will become effective for the fiscal year beginning after December 15, 2008. We are in the process of evaluating the impact SFAS No. 160 will have
on our Groups consolidated financial statements upon adoption.

For more details of recent issued accounting standards, see Note 2(t)
to our consolidated financial statements included elsewhere in this annual report.

C. Research and Development

As of December 31, 2007, our research and development team consisted of 22 research personnel and medical professionals. Our research and development staff consists of medical and biotechnology professionals,
including two PhDs, two MDs and seven holders of masters degrees, many of whom have experience in the healthcare and biotechnology research fields, including experience working in research institutions and hospitals and in proceeding through
the SFDA drug approval process.

We conduct our research and development activities in our facilities in Shenyang. To date, our primary
sources of new clinical products have been our internal research and development activities and the licensing of compounds from third parties. We believe by complementing our internal research and development efforts with a disciplined strategy of
entering into collaborative relationships, we can build a pipeline of diversified pharmaceuticals to drive sustainable revenue growth. For a detailed description of our product pipeline, see Item 4. Information on the CompanyB.
Business OverviewOur Product Pipeline above.

Our research and development expenses for the years ended December 31, 2005,
2006 and 2007 were RMB3.2 million, RMB6.1 million and RMB11.6 million (US$1.6 million), respectively.

D. Trend Information

Please refer to Overview for a discussion of the most significant recent trends in our production, sales, costs and selling prices. In
addition, please also refer to discussions included in this Item for a discussion of known trends, uncertainties, demands, commitments or events that we believe are reasonably likely to have a material effect on our net operating revenues, income
from continuing operations, profitability, liquidity or capital resources, or that would cause reported financial information not necessarily to be indicative of future operating results or financial condition.

E. Off-Balance Sheet Arrangements

We do not
have any outstanding derivative financial instruments, interest rate swap transactions, foreign currency forward contracts, or other off-balance sheet arrangements other than those disclosed in F. Tabular Disclosure of Contractual

B. Compensation

Our directors and
executive officers receive compensation in the form of annual salaries and bonuses. While we do not have a specific bonus plan setting the calculation of our annual bonuses, each director and executive officer is entitled to receive an annual
discretionary bonus based upon his or her performance of such amount as shall be determined by the board of directors and approved by the independent directors.

In 2007, the aggregate cash compensation we paid to our executive officers, including all the directors, was approximately RMB4.3 million (US$0.6 million). As of December 31, 2007, we accrued RMB2.1 million
(US$0.3 million) for bonuses for directors and officers in relation to the services they provided in 2007.

In January 2008, we granted our
director, Lawrence S. Wizel, 1,500 ADSs, which will vest on December 31, 2008.

If we terminate an employment agreement with an
executive officer without cause, we are required to pay compensation equal to one month of his or her salary for each year of his or her service to our company.

Stock Option Plan

We adopted our 2006 stock incentive plan on September 5, 2006, which provides for the grant of stock
options, restricted stock and restricted stock units, each of which we referred to as awards. The 2006 stock incentive plan is administered by the board of directors. The purpose of the plan is to provide additional incentive to those
officers, employees, directors, consultants and other service providers whose contributions are essential to the growth and success of our business, in order to strengthen the commitment of such persons to us and motivate such persons to faithfully
and diligently perform their responsibilities and attract and retain competent and dedicated persons whose efforts will result in our long-term growth and profitability.

We are authorized under the 2006 stock incentive plan to issue direct awards, to sell shares or grant options to purchase shares for up to cumulatively 10% of the issued shares outstanding from time to time. The 2006
stock



77



---

incentive plan provides for the grant to our employees, directors, and consultants or any other participants that the board of directors shall decide in good
faith. The board of directors has complete discretion to select the grantees and to establish the terms and conditions of the grants, subject to the provisions of the 2006 stock incentive plan.

Plan Administration. Our 2006 stock incentive plan is administered by our board of directors or a committee or subcommittee appointed by our board
of directors. In each case, our board of directors or the committee will determine the provisions and terms and conditions of each award grant, including, but not limited to, the exercise price for the options, vesting schedule, form of payment of
exercise price and other applicable terms.

Award Agreement. Awards to be granted under our 2006 stock incentive plan are evidenced
by an award agreement that sets forth the terms and conditions for each award grant, which include, among other things, the vesting schedule, exercise price, type of option and expiration date of each award grant.

Eligibility. We may grant awards to an officer, director, employee, consultant, advisor or another service provider of our company or any of our
parent or subsidiaries, provided that directors of our company or any of our parent or subsidiary who are not also employees of our company or any of our parent or subsidiaries, and consultants or advisors to our company or any of our parent or
subsidiaries may not be granted incentive stock options.

Option Term. The term of each option to be granted under the 2006 stock
incentive plan may not exceed five years from the date of grant.

Exercise Price. In the case of non-qualified stock options, the
per share exercise price of shares purchasable under an option shall be determined by the plan administrator in his or her sole discretion at the time of grant. In the case of incentive stock options, the per share exercise price of shares
purchasable under an option shall not be less than 100% of the fair market value per share at the time of grant. However, if we grant an incentive stock option to an employee, who at the time of that grant owns shares representing more than 10% of
the voting power of all classes of our share capital, the exercise price cannot be less than 110% of the fair market value of our ordinary shares on the date of that grant.

Amendment and Termination. Our board of directors may at any time amend, alter or discontinue the plan, provided that no amendment, alteration or
discontinuation shall be made that would impair the rights of a participant under any award theretofore granted without such participants consent. Unless terminated earlier, our 2006 stock incentive plan shall continue in effect for a term of
five years from the effective date of the plan.

C. Board Practices

Our board of directors currently consists of seven members, including Mr. Lawrence S. Wizel, Mr. Mingde Yu, and Mr. Moujia Qi, all of whom are independent directors within the meaning of Rule
4200(a)(15) of the Nasdaq Marketplace Rules, as amended from time to time. Mr. Dan Lou, our chairman, is the father of Dr. Jing Lou, our chief executive officer.

Our audit committee of the board of directors, consisting of Mr. Lawrence S. Wizel, Mr. Mingde Yu and Mr. Moujia Qi, was established
on October 7, 2006. Since there are no specific requirements under Cayman Islands law on the composition of our audit committee, our practice was established by our board of directors by reference to similarly situated issuers. Our practice is
in line with Rule 4350(d) of the Nasdaq Marketplace Rules that requires the audit committees of United States companies to have a minimum of three independent directors. All members of our audit committee satisfy the independence
requirements of each of the Nasdaq Marketplace Rules and Section 10A(m)(3)(B)(i) of the Securities Exchange Act of 1934, as amended, or the Exchange Act. The audit committee is responsible for overseeing the accounting and financial reporting
processes of our company and audits of our financial statements, including the appointment, compensation and oversight of the work of our independent auditors. Mr. Wizel is the Chairman of the audit committee.

We do not have a compensation committee or nominations committee, nor is independent director involvement required in the selection of director nominees
or in the determination of executive compensation. This home country practice of ours differs from Rule 4350(c) of the Nasdaq Marketplace Rules regarding independent directors involvement in these areas, because there are no specific
requirements under Cayman Islands law on the establishment of compensation committees or nominations committees, and neither are there any requirements on independent directors involvement in the selection of director nominees nor in the
determination of executive compensation.

Duties of Directors

Under Cayman Islands law, our directors have a fiduciary duty to act honestly, in good faith and with a view to our best interests. Our directors also have a duty to exercise the skill they actually possess and such
care and diligence that a reasonably prudent person would exercise in comparable circumstances. In fulfilling their duty of care to us, our directors must ensure compliance with our memorandum and articles of association, as amended from time to
time.

The functions and powers of our board of directors include, among others:



| |  |  | convening shareholders annual general meetings and reporting its work to shareholders at such meetings;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | declaring dividends and distributions;
| | - |  | --------------------------------------



| |  |  | appointing officers and determining the term of office of officers;
| | - |  | -------------------------------------------------------------------



| |  |  | exercising the borrowing powers of our company and mortgaging the property of our company; and
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | approving the transfer of shares of our company, including the registering of such shares in our share register.
| | - |  | ----------------------------------------------------------------------------------------------------------------

Terms of Directors and Executive Officers

Our
articles of association provide for a staggered board of directors. At each annual general meeting of our shareholders, one third of our directors (or, if their number is not a multiple of three, the number nearest to but not greater than one-third)
are required to stand for reelection. The Chairman shall not be required to stand for reelection at any annual meeting, and will serve for an indefinite term. In addition, the Chairman will not be taken into account in determining the number of
directors who must stand for reelection in each year.

The particular directors that must stand for reelection at each annual general
meeting are determined according to a rotation. Should a director choose not to offer himself or herself for reelection at an annual meeting, the number of directors who must stand for reelection at that meeting is reduced accordingly. Directors who
have been longest in office since their last re-election or appointment shall stand for reelection at the annual meeting, provided that, in the case of directors who were last elected on the same day, which director must stand for reelection shall
(unless they otherwise agree among themselves) be determined by lot.

Any director appointed to fill a vacancy shall serve only until the
next annual meeting, and shall not be taken into account in determining which particular directors or the number of directors who are stand for reelection at such annual meeting.

Our executive officers are appointed by and serve at the discretion of our board of directors.

Employment Agreements

We have entered into
employment agreements with all of our executive officers and employees. Under these agreements, each of our executive officers is employed for a specified time period. We may terminate his or her employment for cause at any time, without notice or
remuneration, for certain acts of the employee, including but not limited to a conviction or plea of guilty to a felony or to an act of fraud, misappropriation or embezzlement, negligence or dishonest act to the detriment of the company, or
misconduct of the employee and failure to perform his or her agreed-to duties after a reasonable opportunity to cure the failure. Furthermore, we may terminate the employment without cause at any time, in which case we will pay the employee a
compensation equal to one month of his or her salary for each year of his or her service for our company. An executive officer may terminate the employment at any time upon one month, written notice.



80



---

Each executive officer has agreed to hold, both during and subsequent to the term of the employment
agreement, our confidential information in strict confidence and not to disclose such information to anyone except our other employees who have a need to know such information in connection with our business. The executive officers have also agreed
to assign to us all rights, titles and interests to or in any inventions that they may conceive or develop during the period of employment, including any copyrights, patents, mark work rights, trade secrets or other intellectual property rights
pertaining to such inventions. Specifically, each executive officer has agreed not to, while employed by us and for a period of three years following the termination or expiration of the employment agreement, (i) approach our clients, customers
or contacts or other persons or entities introduced to the executive officer for the purposes of doing business with such persons or entities, and will not interfere with the business relationship between us and such persons and/or entities;
(ii) assume employment with or provide services as a director or otherwise for any of our competitors, or engage, whether as principal, partner, licensor or otherwise, in any business which is in direct or indirect competition with our
business; or (iii) seek directly or indirectly, to solicit the services of any of our employees employed by us at or after the date of the executive officers termination, or in the year preceding such termination.

Foreign Currency
Exchange

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



| |  |  | Foreign Currency Administration Rules (1996), as amended, or the Exchange Rules; and
| | - |  | ------------------------------------------------------------------------------------



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

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

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

E. Taxation

Cayman Islands Taxation

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

United States Federal Income Tax Considerations for U.S. Persons

The following is a summary of the material United States federal income tax considerations relating to the acquisition, ownership, and disposition of ADSs
or ordinary shares by U.S. Holders (as defined below) that will hold their ADSs or ordinary shares as capital assets (generally, property held for investment) under the United States Internal Revenue Code (the Code). This
summary is based upon existing United States federal income tax law, which is subject to differing interpretations or change, possibly with retroactive effect. This summary does not discuss all aspects of United States federal income taxation that
may be important to particular investors in light of their individual circumstances, and does not deal with the tax consequences to investors subject to special tax rules (for example, financial institutions, insurance companies, broker-dealers,
partnerships and their partners, and tax-exempt organizations (including private foundations)), holders who are not U.S. Holders, holders who own (directly, indirectly, or constructively) 10% or more of our voting stock, investors that will hold
ADSs or ordinary shares as part of a straddle, hedge, conversion, constructive sale, or other integrated transaction for United States federal income tax purposes, or investors that have a functional currency other than the United States dollar, all
of whom may be subject to tax rules that differ significantly from those summarized below.

This discussion is not a comprehensive
description of all of the U.S. federal tax consequences that may be relevant with respect to the ownership and disposition of ADSs or ordinary shares. We urge you to consult your own tax advisor regarding your particular circumstances and the U.S.
federal income and estate tax consequences to you of owning and disposing of ADSs or ordinary shares, as well as any tax consequences arising under the laws of any state, local or foreign or other tax jurisdiction and the possible effects of changes
in U.S. federal or other tax laws.

General

For purposes of this summary, a U.S. Holder is a beneficial owner of ADSs or ordinary shares that is, for United States federal income tax purposes, (i) an individual who is a citizen or resident of
the United States; (ii) a corporation or other entity taxable as a corporation for United States federal income tax purposes, created in, or organized under the law of, the United States or any State or the District of Columbia; (iii) an
estate, the income of which is includible in gross income for United States federal income tax purposes regardless of its source; or (iv) a trust (A) the administration of which is subject to the primary supervision of a United States
court and which has one or more United States persons who have the authority to control all substantial decisions of the trust or (B) that has otherwise validly elected to be treated as a United States person under the Code.

If a partnership is a beneficial owner of our ADSs or ordinary shares, the tax treatment of a partner in the partnership will generally depend upon the
status of the partner and the activities of the partnership.

For United States federal income tax purposes, U.S. Holders of ADSs will be
treated as the beneficial owners of the underlying shares represented by the ADSs.

Threshold PFIC Classification Matters.

A non-United States corporation, such as the company, will be treated as a passive foreign investment company (a
PFIC), for United States federal income tax purposes, if 75% or more of its gross income consists



86



---

of certain types of passive income or 50% or more of its assets (based on an average of the quarterly values during a taxable year) are
classified as assets that either produce passive income or are held for the production of passive income. Passive income includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and
securities, and certain gains from commodities transactions.

Certain look through rules apply for purposes of the income and
asset tests described above. If we own, directly or indirectly, 25% or more of the total value of the outstanding shares of another foreign corporation, we will be treated as if we held directly a proportionate share of the other corporations
assets and received directly a proportionate share of the other corporations income. The determination of whether we are, or will become, classified as a PFIC is a fact intensive determination that is made annually based on the composition and
amounts of income that we earn and the composition and valuation of our assets, all of which are subject to change. For this purpose, cash is categorized as a passive asset and the companys unbooked intangibles are taken into account.

Based upon the composition and valuation of our assets, we do not believe that we were a PFIC for our taxable year ending
December 31, 2007. Based on our current income and assets, it is uncertain whether we will be classified as a PFIC for United States federal income tax purposes for our current taxable year ending December 31, 2008, a determination that
can only be made after the close of the taxable year, or future taxable years. The overall level of our passive assets will be significantly affected by the amount and time-frame within which we disperse the cash raised in our initial public
offering, and other liquid assets that we presently hold, for the purpose of the capital expenditures described in this annual report or other projects.

Additionally, in estimating the value of our goodwill and other unbooked intangibles, we have taken into account our market capitalization. Among other matters, if our market capitalization subsequently declines, we
may be or become classified as a PFIC for the current or one or more future taxable years. Further, while we believe our valuation approach is reasonable, it is possible that the Internal Revenue Service may challenge the valuation of our goodwill
and other unbooked intangibles, which may result in the company being classified as a PFIC for the taxable year ending December 31, 2007, the current taxable year, or one or more future taxable years. If we are classified as a PFIC for any year
during which a U.S. Holder holds our ADSs or ordinary shares, we generally will continue to be treated as a PFIC for all succeeding years during which such U.S. Holder holds our ADSs or ordinary shares.

Because PFIC status is a fact intensive determination made on an annual basis, no assurance can be given that we are not or will not become classified as
a PFIC and will depend upon, in great measure, the timing of our capital expenditures and the value of our unbooked intangibles. The discussion below under Distributions on ADSs or Ordinary Shares and Sale or Other Disposition of
ADSs or Ordinary Shares is written on the basis that we will not be classified as a PFIC for United States federal income tax purposes. The discussion further below under Passive Foreign Investment Company summarizes the PFIC rules
that would be applicable to an investment in our ADSs or ordinary shares if we were to be or become classified as a PFIC.

Distributions on ADSs or
Ordinary Shares

We do not currently intend to pay dividends in the foreseeable future. Any cash distributions paid on ADSs or
ordinary shares out of our earnings and profits, as determined under United States federal income tax principles, will be includible in the gross income of a U.S. Holder as dividend income. Because we do not intend to determine our earnings and
profits on the basis of United States federal income tax principles, any distribution paid will generally be treated as a dividend for United States federal income tax purposes. For taxable years beginning before January 1, 2011, a
non-corporate recipient of dividend income generally will be subject to tax on dividend income from a qualified foreign corporation at a maximum United States federal tax rate of 15% rather than the marginal tax rates generally
applicable to ordinary income provided that certain holding period requirements are met. A non-United States corporation (other than a corporation that is classified as a PFIC for the taxable year in which the dividend is paid or the preceding
taxable year) generally will be considered to be a



87



---

qualified foreign corporation (i) if it is eligible for the benefits of a comprehensive tax treaty with the United States which the Secretary of
Treasury of the United States determines is satisfactory for purposes of this provision and which includes an exchange of information program or (ii) with respect to any dividend it pays on stock which is readily tradable on an established
securities market in the United States. There is currently no tax treaty in effect between the United States and the Cayman Islands. It is expected that our ADSs will be readily tradable as a result of being listed on The NASDAQ Stock
Market LLC, an established securities market in the United States.

In addition, for dividends to qualify for the reduced rate, you
generally must have held the ADSs or ordinary shares for more than 60 days during the 121-day period beginning 60 days prior to the ex-dividend date. However, your holding period will be reduced for any period during which the risk of loss is
diminished. Moreover, a dividend will not qualify for the reduced rate to the extent you are under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related
property.

Cash distributions in excess of our earnings and profits will be treated as a tax-free return of capital to the extent of the
U.S. Holders adjusted tax basis in its ADSs or ordinary shares, and thereafter as gain from the sale or exchange of a capital asset. The amount of any cash distribution paid in Renminbi should equal the United States dollar value of the
Renminbi on the date of the distribution, regardless of whether the Renminbi is actually converted into United States dollars at that time. Gain or loss, if any, recognized on a subsequent sale, conversion, or other disposition of Renminbi generally
will be United States source ordinary income or loss. Dividends received on the ADSs or ordinary shares will not be eligible for the dividends received deduction allowed to corporations.

A U.S. Holder may be eligible, subject to a number of complex limitations, to claim a foreign tax credit in respect of any foreign withholding taxes
imposed on dividends received on ADSs or ordinary shares. Dividends generally will be treated as income from foreign sources for United States foreign tax credit purposes. The foreign tax credit limitation is calculated separately with respect to
specific classes of income. For this purpose, distributions characterized as dividends distributed by us will generally constitute passive category income or, in the case of certain U.S. Holders, general category income. A
U.S. Holder who does not elect to claim a foreign tax credit for such withholding taxes, may instead claim a deduction, for United States federal income tax purposes, in respect of such withholdings, but only for a year in which such holder elects
to do so for all creditable foreign income taxes.

Dispositions of ADSs or Ordinary Shares

Subject to the discussion in Passive Foreign Investment Company below, you generally will recognize taxable gain or loss realized on the sale
or other taxable disposition of ADSs or ordinary shares equal to the difference between the U.S. dollar value of (i) the amount realized on the disposition (i.e., the amount of cash plus the fair market value of any property received), and
(ii) your adjusted tax basis in the ADSs or ordinary shares. Such gain or loss will be capital gain or loss.

If you have held the
ADSs or ordinary shares for more than one year at the time of disposition, such capital gain or loss will be long-term capital gain or loss. Preferential tax rates for long-term capital gain (currently, with a maximum rate of 15% for taxable years
beginning before January 1, 2011) will apply to non-corporate U.S. Holders. If you have held the ADSs or ordinary shares for one year or less, such capital gain or loss will be short-term capital gain or loss taxable as ordinary income at your
marginal income tax rate. The deductibility of capital losses is subject to limitations. Generally, any gain or loss recognized will not give rise to foreign source income for U.S. foreign tax credit purposes.

You should consult your own tax advisor regarding the U.S. federal income tax consequences if you receive currency other than U.S. dollars upon the
disposition of ADSs or ordinary shares.

Passive Foreign Investment Company

If we are or were to become classified as a PFIC for any taxable year during which you hold our ADSs or ordinary shares, unless you make a
mark-to-market election (as described below), you would be subject to special rules with respect to (i) any gain realized on the sale or other disposition of ADSs or ordinary shares, and (ii) any excess distribution
made by us on ADSs or ordinary shares (generally, any distributions paid to you in respect of ADSs or ordinary shares during a single taxable year that are greater than 125% of the average annual distributions received by you during the three
preceding taxable years or, if shorter, your holding period for such ADSs or ordinary shares).

Under the PFIC rules:



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



| |  |  | the amount allocated to the taxable year in which the gain or excess distribution was realized, and any taxable year prior to the first taxable year that you held
ADSs or ordinary shares in which we are classified as a PFIC (a pre-PFIC year), would be taxable as ordinary income; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to each prior year, other than the current year and any pre-PFIC year, would be subject to tax at the highest tax rate in effect for that year,
and an interest charge generally applicable to underpayments of tax would be imposed on the resulting tax for each such year for the period it had been deferred.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, notwithstanding any election you may make, dividends that you receive from us will not be eligible for the preferential tax rates applicable
to distributions made by qualified foreign corporations (as discussed above in Distributions on ADSs or Ordinary Shares).

As an alternative to the foregoing rules, a holder of marketable stock in a PFIC may make a mark-to-market election, provided that the shares are regularly traded on a qualified exchange, such as The
NASDAQ Stock Market LLC. Stock is regularly traded for any calendar year during which it is traded (other than in de minimis quantities) during each calendar quarter. While the company anticipates that the ADSs will qualify as being
regularly traded on The NASDAQ Stock Market LLC, no assurances may be given that the ADSs will qualify as being regularly traded on such exchange. If you make a valid mark-to-market election, you will generally (i) include as
ordinary income for each taxable year the excess, if any, of the fair market value of your ADSs as determined at the end of the taxable year over the adjusted tax basis of such ADSs and (ii) deduct as an ordinary loss the excess, if any, of the
adjusted tax basis of your ADSs over the fair market value of such ADSs as determined at the end of the taxable year, but only to the extent of the amount previously included in income as a result of the mark-to-market election. Your adjusted tax
basis in your ADSs would be adjusted to reflect any income or loss resulting from the mark-to-market election.

Alternatively, if you make
an election to treat the company as a qualified electing fund (QEF Election) you generally will not be subject to the special rules discussed above. Instead, you will be subject to current U.S. federal income tax on your pro
rata share of our ordinary earnings and net capital gain, regardless of whether such amounts are actually distributed to you by us. However, you can make a QEF Election only if we agree to furnish you annually with certain tax information and we
currently do not intend to prepare or provide such information.

If you own ADSs or ordinary shares during any year that we are classified
as a PFIC, you must file an annual Internal Revenue Service Form 8621 that describes the distributions received on ADSs or ordinary shares and the gain realized on the disposition of ADSs or ordinary shares. You are urged to consult your tax advisor
concerning the United States federal income tax consequences of acquiring, holding, and disposing of ADSs or ordinary shares if we are or become classified as a PFIC, including the possibility of making a mark-to-market election.

Information Reporting and Backup Withholding

Generally, information reporting requirements will apply to distributions on ADSs or ordinary shares or proceeds on the disposition of ADSs or ordinary
shares paid within the United States (and, in certain cases, outside the United States) to U.S. Holders other than certain exempt recipients, such as corporations. Furthermore, backup withholding (currently at 28%) may apply to such amounts if the
U.S. Holder fails to (i) provide a correct taxpayer identification number, (ii) report interest and dividends required to be shown on its U.S. federal income tax return, or (iii) make other appropriate certifications in the required
manner. U.S. Holders who are required to establish their exempt status generally must provide such certification on IRS Form W-9.

Backup
withholding is not an additional tax. Amounts withheld as backup withholding from a payment to you may be credited against your U.S. federal income tax liability and you may obtain a refund of any excess amounts withheld by filing the appropriate
claim for refund with the IRS and furnishing any required information in a timely manner.

F. Dividends and Paying Agents

ITEM 11.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
RISK

Market Risk and Risk Management

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 market risk associated with interest rate movements and currency rate movements on non-U.S. dollar denominated assets and liabilities.

Interest Rate Risk

The Peoples Bank of China has the sole authority in China to establish the official interest rates
for Renminbi-denominated loans. Financial institutions in China set their effective interest rates within the range established by the Peoples Bank of China. Interest rates and payment methods on loans denominated in foreign currencies are set
by financial institutions based on interest rate changes in the international financial market, cost of funds, risk levels and other factors.

We currently have no short-term or long-term bank loans, but if we incur any such indebtedness in the future, we will be subject to market risks due to fluctuations in interest rates on that debt. Increases in interest rates will increase
the cost of new borrowing. Accordingly, fluctuations in interest rates can lead to significant fluctuations in the fair value of any such debt instruments.

Foreign Currency Risk

We conduct our business primarily in Renminbi, which is also our functional and reporting currency.
The Renminbi is not a fully convertible currency. The conversion of Renminbi into foreign currencies, including U.S. dollars, has been based on rates set by the Peoples Bank of China. On July 21, 2005, the PRC government changed its
decade-old policy of pegging the value of Renminbi to the U.S. dollar. Under the new policy, Renminbi is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. This change in policy has resulted in an
approximately 11.9% appreciation of Renminbi against the U.S. dollar by December 31, 2007. There remains significant international pressure on the PRC government to adopt an even more flexible currency policy, which could result in a further
and more significant appreciation of the Renminbi against the U.S. dollar. We have not used any forward contracts or currency borrowings to hedge our exposure to foreign currency exchange risk.

We are exposed to foreign currency risk primarily as a result of purchases of certain raw materials and equipment from overseas, and export sales. In
addition, to the extent that we need to convert U.S. dollars we have received from our initial public offering into Renminbi for our operations, fluctuation in the exchange rate between the Renminbi and U.S. dollar would affect the Renminbi amount
we receive from the conversion.

|ITEM 15T.    CONTROLS | AND PROCEDURES
|--------------------- | --------------

Evaluation of disclosure controls and procedures

We maintain disclosure controls and procedures, as such term is defined in Rule 13a  15(e) under the Exchange Act,
that are designed to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in
Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding
required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving the desired
control objectives.

As required by Rule 13a-15(b) under the Exchange Act, we carried out an evaluation, under the supervision and with the
participation of the Companys management, including our chief executive officer and our chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the fiscal year
covered by this report. Based on their evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures were effective at a reasonable assurance level.

Changes in Internal Controls

There were no changes
in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15 or 15d-15 that occurred during the period covered by this annual report that has materially affected, or is reasonably likely to
materially affect, our internal control over financial reporting.

In addition, under the supervision and with the participation of our
senior management, including our chief executive officer and chief financial officer, we are in the process of conducting further evaluation of our internal control over financial reporting for compliance with the requirements of Section 404
under the Sarbanes-Oxley Act. In this regard, we have engaged a third party professional advisor to assist us in evaluating, designing, implementing and testing internal control over financial reporting intended to comply with the requirements of
Section 404. As we are still in the evaluation process, we may identify material weaknesses or significant deficiencies in the future. Should we discover such conditions, we intend to remediate them as soon as practicable. We are committed to
taking appropriate steps for remediation, as needed.



|ITEM 16A.    AUDIT | COMMITTEE FINANCIAL EXPERT

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of

3SBio Inc.

We have audited the accompanying consolidated balance sheets of 3SBio Inc. (the Company) and subsidiaries as of December 31, 2006 and
2007, and the related consolidated statements of income and comprehensive income, shareholders equity and cash flows for each of the years in the three-year period ended December 31, 2007, all expressed in Renminbi. 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 also 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 3SBio Inc. and subsidiaries as of December 31, 2006 and 2007, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2007, in conformity with
U.S. generally accepted accounting principles.

The accompanying consolidated financial statements as of and for the year ended
December 31, 2007 have been translated into United States dollars solely for the convenience of the reader. We have audited the translation and, in our opinion, such consolidated financial statements expressed in Renminbi have been translated
into United States dollars on the basis set forth in note 2(b) to the consolidated financial statements.

option and the Company issued an additional 252,634 ADSs, representing 1,768,438 ordinary shares, at US$16 per ADS. The selling shareholders also sold an additional 499,506 ADSs, representing 3,496,542 ordinary shares. The Company raised additional
net proceeds of approximately RMB28,334,000 (equivalent to approximately US$3,661,000 at the date of transaction) from the exercise of the over-allotment option by the underwriters.

In connection with the IPO, the Company received net proceeds (after deduction of the related issuance costs totalling RMB87,094,000) of RMB836,288,000.

(b) Reorganization

The Company
was incorporated in the Cayman Islands in August 2006 under the Cayman Islands Companies Law as an exempted company with limited liability. The Company was incorporated as part of the reorganization of Shenyang Sunshine Pharmaceutical Company
Limited (Shenyang Sunshine) and its subsidiaries (the Reorganization) in preparation of the Companys IPO. In connection with the Reorganization, and pursuant to a shareholders agreement amongst the existing
beneficial shareholders of Shenyang Sunshine, an ultimate beneficial shareholder of Shenyang Sunshine established Collected Mind Limited (Collected Mind) in July 2006 in the British Virgin Islands and held the interest in Collected Mind
on behalf of all the ultimate beneficial shareholders of Shenyang Sunshine or their nominees, in proportion to their respective effective share ownership in Shenyang Sunshine. Collected Mind acquired all of the equity interest in Shenyang Sunshine
in August 2006. Shortly after this acquisition, the Company was established as the ultimate holding company. In September 2006, in consideration of the Companys issuance of shares to the ultimate beneficial shareholders of Collected Mind or
their nominees in proportion to each of their beneficial interest in Collected Mind, the entire

(b) Reorganization(Continued)



equity interest in Collected Mind was acquired by the Company. Upon completion of the Reorganization, Collected Mind and the Company became Shenyang
Sunshines immediate and ultimate holding companies, respectively. The proportionate ownership of the Company immediately after the Reorganization is substantially the same.

Shenyang Sunshine was established in the PRC in January 1993 as a Sino-foreign joint stock limited company with registered, issued and paid up capital of
62,974,046 shares of RMB1 each. In connection with the Reorganization, Shenyang Sunshine became a wholly foreign-owned enterprise in the PRC.

Shenyang Sunshine has investments in two variable interest entities (VIEs) for which Shenyang Sunshine is the primary beneficiary, namely Liaoning Bio-Pharmaceutical Company Limited (Liaoning Sunshine) and Beijing
Sunshine Bio-Product Sales Company Limited (Beijing Sunshine). Liaoning Sunshine and Beijing Sunshine are domestic limited liability companies incorporated in the PRC and are primarily engaged in the distribution of products manufactured
by Shenyang Sunshine.

Prior to the Reorganization, Shenyang Sunshine held 90% and 45% equity interests in Liaoning Sunshine and Beijing
Sunshine, respectively, with the remaining interests in the two companies held by the former majority shareholder of Shenyang Sunshine, Shenyang Keweier Advanced Technology Co., Ltd. (Shenyang Keweier). Prior to the Reorganization,
Shenyang Sunshine consolidated both Liaoning Sunshine and Beijing Sunshine since it held a 90% controlling interest in Liaoning Sunshine and it was the primary beneficiary of Beijing Sunshine, which was deemed to be a VIE in accordance with
Financial Accounting Standards Board (FASB) Interpretation No. 46 (revised December 2003), Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51(FIN 46(R)). FIN 46(R) requires certain
VIEs to be consolidated by the primary beneficiary of the entity if the equity investors in the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its
activities without subordinated financial support from other parties. FIN 46(R) also requires that, for purposes of determining whether an enterprise is the primary beneficiary of a VIE, an enterprise with a variable interest shall treat variable
interests in the same entity held by its related parties as its own interests. Specifically, the total equity investment at risk of Beijing Sunshine is deemed insufficient to fund its activities without additional subordinated financial support from
Shenyang Sunshine which is in the form of subordinated trade payables arising from the sales of products from Shenyang Sunshine to Beijing Sunshine.

In connection with the Reorganization and for purposes of compliance with certain PRC rules and regulations related to the distribution of pharmaceutical products, Shenyang Sunshine transferred its 45% equity interest
in Beijing Sunshine to an executive officer in October 2006 and its 90% equity interest in Liaoning Sunshine to a director in November 2006. In December 2006 and January 2007, Shenyang Sunshine entered into certain contractual arrangements with
Beijing Sunshine and Liaoning Sunshine, respectively, such that:



| |  |  | Shenyang Sunshine is entitled to a majority of the revenues of Beijing Sunshine and Liaoning Sunshine which are derived in the form of technology support, market
development and consulting service fees;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Shenyang Sunshine is granted an exclusive right to acquire, to the extent permissible under PRC law, the equity interests in Liaoning Sunshine and Beijing Sunshine;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the equity holders of Liaoning Sunshine and Beijing Sunshine are required to consult with and follow any lawful instruction of Shenyang Sunshine whenever they
exercise their rights as the equity holders of Liaoning Sunshine and Beijing Sunshine; and

(b) Reorganization(Continued)



| |  |  | the equity interests in Liaoning Sunshine and Beijing Sunshine are pledged to Shenyang Sunshine to guarantee the obligations of the equity holders under the above
contractual arrangements.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As a result of the above contractual arrangements, Shenyang Sunshine bears economic risks with
respect to, and derives economic benefits from, the operations of Liaoning Sunshine and Beijing Sunshine. As Shenyang Sunshine continues to hold the predominant variable interests in Liaoning Sunshine and Beijing Sunshine, it is deemed to be the
primary beneficiary of both entities under FIN 46(R). Accordingly, the transfers of equity interests in Liaoning Sunshine and Beijing Sunshine did not change the requirement to consolidate the two entities and the financial statements of Liaoning
Sunshine and Beijing Sunshine continue to be included in the Companys consolidated financial statements subsequent to the Reorganization.

(c)
Basis of presentation

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally
accepted accounting principles (U.S. GAAP).

As the Reorganization was completed for the sole purpose of establishing the legal
structure of the Group in preparation for the initial public offering of securities of the Company, and as the shareholders proportionate equity interests in the Company upon consummation of the Reorganization were substantially identical to
their proportionate equity interests in Shenyang Sunshine just prior to the consummation of the Reorganization, the Reorganization has been accounted for in a manner similar to a pooling-of-interests. Accordingly, the accompanying consolidated
financial statements of the Company include the assets and liabilities of Shenyang Sunshine at their historical carrying amounts. In addition, the accompanying consolidated financial statements present the results of the Group as if Collected Mind,
Shenyang Sunshine and its subsidiaries were transferred to the Company as of the beginning of the earliest period presented.

This basis of
accounting differs in certain material respects from that used for the preparation of the books of account of Shenyang Sunshine and its subsidiaries, which are prepared in accordance with the accounting principles and the relevant financial
regulations applicable to enterprises limited by shares as established by the Ministry of Finance of the PRC (PRC GAAP), the accounting standards used in the country of their domicile. The accompanying consolidated financial statements
reflect necessary adjustments not recorded in the books of account of Shenyang Sunshine and its subsidiaries to present them in conformity with U.S. GAAP.

2 Summary of significant accounting policies and practices

(a) Principles of consolidation

The consolidated financial statements include the financial statements of the Company and its subsidiaries, including the VIEs of which it is the primary
beneficiary, as defined by FIN 46(R). All significant intercompany balances and transactions have been eliminated on consolidation.

Where
losses applicable to the minority exceed the minoritys interest in the equity of a subsidiary, the excess, and any further losses applicable to the minority, are charged against the Groups interest except to the extent that the minority
has a binding obligation to, and is able to, make additional investment to cover the losses. If the subsidiary subsequently reports profits, the Groups interest is allocated all such profits until the minoritys share of losses previously
absorbed by the Group has been recovered.

(b) Foreign currency transactions

The functional currency of Shenyang Sunshine, Liaoning Sunshine and Beijing Sunshine is Renminbi (RMB), whereas the functional currency of the Company is the U.S. dollar (US$). The reporting
currency of the Group is RMB.

Transactions of Shenyang Sunshine, Liaoning Sunshine and Beijing Sunshine denominated in currencies other
than RMB are translated into RMB at the exchange rates quoted by the Peoples Bank of China (the PBOC) prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated
into RMB using the applicable exchange rates quoted by the PBOC at the balance sheet dates. The resulting exchange differences are recorded as other income/expenses in the consolidated statements of income and comprehensive income.

Assets and liabilities of the Company are translated into RMB using the exchange rate on the balance sheet date. Income and expenses are translated at
average exchange rates prevailing during the year. The gains and losses resulting from translation of financial statements of the Company are recorded as a separate component of accumulated other comprehensive income/loss within shareholders
equity.

RMB is not a fully convertible currency. All foreign exchange transactions involving RMB must take place either through the PBOC
or other institutions authorized to buy and sell foreign exchange. Commencing from July 21, 2005, the PRC government moved the RMB into a managed floating exchange rate regime based on market supply and demand with reference to a basket of
currencies. The exchange rate has continued to fluctuate since the initial adjustment.

For the convenience of the readers, certain 2007
RMB amounts included in the accompanying consolidated financial statements have been translated into U.S. dollars at the rate of US$1.00 = RMB7.2946, being the noon buying rate for U.S. dollars in effect on December 31, 2007 for cable transfers
in RMB per U.S. dollar as certified for custom 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 31, 2007 or on any other date.

(c) Use of estimates

The preparation of the consolidated financial statements in accordance with U.S. GAAP requires management of the Company to make a number of estimates and
assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities on the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates. On an ongoing basis, management reviews its estimates and assumptions including, but not limited to, those related to the recoverability of the carrying amount and estimated useful lives of
long-lived assets; realizability of inventories; allowance for uncollectible accounts receivables; valuation allowance for deferred tax assets; and the fair value of share-based compensation. Changes in facts and circumstances may result in revised
estimates.

(d) Cash and cash equivalents

Cash and cash equivalents consist of cash on hand, interest-bearing deposits placed with banks and short-term, highly liquid investments with original maturities of three months or less. None of the Groups cash
is restricted as to withdrawal.

(d) Cash and cash equivalents(Continued)



As of December 2007, cash and cash equivalents of RMB 95,548,000 (US$ 13,099,000) was held in major financial institutions located in the PRC, and cash and cash equivalents of
RMB 715,478,000 (US$ 98,083,000) was held in major financial institutions located in Hong Kong. Further, as of December 31, 2007, the Companys cash and cash equivalents included U.S. dollar denominated bank deposits of
US$ 185,000 (equivalent to RMB 1,350,000), in major institutions located in the PRC, and US$ 97,845,000 (equivalent to RMB 713,740,000), in major financial institutions located in Hong Kong. Management believes that
these major financial institutions are of high credit quality.

(e) Accounts receivable

Accounts receivable are stated at the invoiced amount after deduction of trade discounts and allowances, if any, and do not bear interest. The allowance
for doubtful accounts is the Groups best estimate of the amount of credit losses in the Groups existing accounts receivable. The Group determines the allowance based on historical write-off experience, customer specific facts and
economic conditions.

Outstanding account balances are reviewed individually for collectibility. Account balances are written off after all
means of collection have been exhausted and the potential for recovery is considered remote. Shenyang Sunshine and its subsidiaries are required to comply with local tax requirements on the write-offs of doubtful accounts, which allow for such
write-offs only when the related account balances are aged over three years and sufficient evidence is available to prove the debtors inability to make payments. For financial reporting purposes, Shenyang Sunshine and its subsidiaries
generally record write-offs of doubtful account at the same time the local tax requirements for the write-offs are met. As a result, there are generally time lags between the time when a provision for doubtful accounts is recorded and the time the
doubtful accounts are written off against the related allowance. The Group does not have any off-balance-sheet credit exposure related to its customers.

(f) Inventories

Inventories are stated at the lower of cost or market. Cost is determined using the weighted average
cost method. Cost of work-in-progress and finished goods comprises direct materials, direct production cost and an allocated proportion of production overheads based on normal operating capacity.

(g) Investment securities

Investment
securities consist of debt securities, including structured notes which have been classified as available-for-sale securities and structured deposit.

Available-for-sale debt securities other than structured notes are recorded at fair value. Unrealized holding gains and losses, net of the related tax effect, if any, reported as a separate component of accumulated
other comprehensive income/loss until realized.

Structured notes for which the Company has determined do not include an embedded
derivative are recorded at amortized cost calculated as the present value of estimated future cash flows using an effective yield, which is the yield that equates all past actual and current estimated future cash flow streams to the initial
investment.

(g) Investment securities(Continued)



Financial instruments for which the Company has determined contain an embedded derivative is classified as structured deposits. Structured deposit that contains embedded derivative that is considered not
closely related to the debt security host contract is measured as a single financial instrument at fair value. Any unrealized gains or losses arising from the re-measurement of structured deposits at fair value are recognized in the statements of
income.

Realized gains and losses from the sale of available-for-sale securities are determined on a specific-identification basis.

A decline in the market value of any available-for-sale security that is deemed to be other-than-temporary results in an impairment to
reduce the carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the security is established. To determine whether an impairment is other-than-temporary, the Company considers whether it has the ability and
intent to hold the investment until a market price recovery and considers whether evidence indicating the cost 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 impairment, changes in value subsequent to year-end, forecasted performance of the investee, and the general market condition in the geographic area or industry the investee operates in.

Interest income from debt securities are recognized in other income when earned. Interest income from structure notes are recognized in other income
using the retrospective interest method. Under the retrospective interest method, income for the current period is measured as the difference between the amortized cost at the end of the period and the amortized cost at the beginning of the period,
plus any cash received during the period.

(h) Property, plant and equipment

Property, plant and equipment are stated at cost less accumulated depreciation.

Depreciation on property, plant and equipment is calculated based on the straight-line method (after taking into account their respective estimated
residual values) over the estimated useful lives of the assets as follows:



|                                           |  |           
|------------------------------------------ |  | ----------
|Buildings                                  |  | 20 years  
|Plant and machinery                        |  | 510 years
|Motor vehicles                             |  | 5 years   
|Furniture, fixtures and computer equipment |  | 510 years

Interest expense incurred related to the construction of property, plant and equipment is
capitalized. The capitalization of interest expense as part of the cost of a qualifying asset commences when expenditures for the asset have been made, activities that are necessary to get the asset ready for its intended use are in progress and
interest cost is being incurred. The capitalization period ends when the asset is substantially complete and ready for its intended use.

No depreciation is provided in respect of construction-in-progress.

Depreciation of property, plant and equipment attributable to
manufacturing activities is capitalized as part of inventory, and expensed to cost of revenues when inventory is sold.

(i) Lease prepayments

Lease prepayments represent the cost of land use rights in the PRC. Land use rights are carried at cost and recognized as expense on a straight-line basis over the respective periods of the rights of 30 years.

The current portion of lease prepayments represents the amount expected to be recognized as expense within one year from the balance sheet date, which
has been included in prepaid expenses and other receivables in the consolidated balance sheets.

(j) Impairment of long-lived assets

Long-lived assets, including property, plant and equipment and intangible assets with finite useful lives, are reviewed for
impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Recoverability of long-lived assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset
exceeds its estimated future undiscounted cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Fair value is measured by the assets discounted cash flows or
market value, if readily determinable.

(k) Revenue recognition

Sales of pharmaceutical products represent the invoiced value of goods, net of value added taxes (VAT), sales returns, trade discounts and allowances. The Group recognizes revenue when products are
delivered and the customer takes ownership and assumes risk of loss, collection of the relevant receivable is probable, persuasive evidence of an arrangement exists and the sales price is fixed or determinable.

In the PRC, VAT at a general rate of 17% on invoice amount is collected on behalf of tax authorities in respect of the sales of goods. Revenue is stated
net of VAT. VAT collected from customers is offset with VAT paid by the Group for purchases, with the net amount recorded as a liability in the consolidated balance sheet until it is paid to the authorities.

(l) Government grants

An unconditional
government grant is recognized in the consolidated statement of income and comprehensive income when the grant becomes receivable. The government grants received by the Group were lump sum payments for which approval is at the sole discretion of the
government and are subject to availability of the government funds. The amount and timing of the grants cannot be directly attributable to specific expenditures incurred and the timing of incurrence of such expenditures. As such, grant income is
recognized as other income in the consolidated statement of income and comprehensive income rather than as part of the Companys operating income.

Government grants relating to the acquisition of property, plant and equipment are recognized in the consolidated balance sheet as deferred income when there is reasonable assurance that it will be received and
amortized as other income over the weighted average useful life of the assets purchased under the related

subsidized capital project. Grants that compensate the Group for expenses incurred on research and development activities are recognized as other income in
the consolidated statement of income and comprehensive income upon the later of the award of the grant or in the same period in which the related expenses are incurred.

(m) Retirement and other postretirement benefits

Contributions to retirement schemes (which
are defined contribution plans) are charged to the consolidated statements of income and comprehensive income as and when the related employee service is provided.

(n) Income taxes

Income taxes are accounted for under the asset and liability method. Deferred 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 operating loss and tax credit
carryforwards. Deferred 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. A valuation allowance is provided
to reduce the amount of deferred tax assets if it is considered more likely than not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred tax assets and liabilities of a change in tax rate is recognized
in the consolidated statement of income and comprehensive income in the period that includes the enactment date.

(o) Advertising and research and
development costs

Advertising and research and development costs are expensed as incurred. Advertising costs included in sales,
marketing and distribution expenses amounted to RMB2,725,000, RMB2,022,000 and RMB3,028,000 (US$415,000) for the years ended December 31, 2005, 2006 and 2007 respectively. Research and development costs consist primarily of the remuneration of
research and development staff, depreciation and material costs.

(p) Commitments and contingencies

In the normal course of business, the Group is subject to contingencies, including legal proceedings and claims arising out of the business that relate to
a wide range of matters, including among others, product liability. The Group records accruals for such contingency based upon the assessment of the probability of occurrence and, where determinable, an estimate of the liability. The Group may
consider many factors in making these assessments including past history and the specifics of each matter. As the Group has not become aware of any product liability claim since operations commenced, the Group has not recognized a liability for
product liability claims.

(q) Income per share

In accordance with Statement of Financial Accounting Standards (SFAS) No. 128, Earnings per Share, basic net income per share is computed by dividing net income by the weighted average number
of ordinary shares outstanding. For the years ended December 31, 2005 and 2006, basic net income per share is computed by dividing net income by the number of shares outstanding of 100,000,998 as if the Reorganization as described in Note 1(b)
had occurred at the beginning of the earliest period presented and such shares had been outstanding for

all periods through the date of the Reorganization. Diluted net income per share is calculated by dividing net income by the weighted average number of
ordinary and dilutive potential ordinary shares outstanding during the period. There were no potential ordinary shares during the year ended December 31, 2005. As of December 31, 2006 and 2007, there were 15,000 potential ordinary shares
and 1,060,000 share options respectively, which were related to nonvested shares and share options granted to executives respectively.

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

The diluted net income per share calculation for the year ended December 31, 2006 and 2007
did not include the effect of share options to purchase a total of 1,060,000 and 100,000 ordinary shares, respectively because to do so would have been anti-dilutive.

(r) Share-based payments

SFAS No. 123 (revised 2004), Share-Based Payment
(SFAS No. 123R), requires that all compensation cost related to employee share options or similar equity instruments be measured at the fair value of the award and recognized on a straight-line basis over the requisite service
period, which is generally the same as the vesting period. Compensation cost for share options granted is measured based on the estimated grant date fair value using the Black-Scholes option-pricing model.

(s) Segment reporting

The Group uses the
management approach in determining its operating segments. The management approach considers the internal organization and reporting used by the Groups chief operating decision maker for making operating decisions, allocating resources and
assessing performance as the source of determining the Groups reportable operating segments. Management, including the chief operating decision maker, reviews operating results solely by monthly revenue and operating results of the Group and,
as such, the Group has determined that the Group has a single operating segment as defined by SFAS No. 131, Disclosure about Segments of an Enterprise and Related Information, which is the research, development, manufacture and
distribution of pharmaceutical products in the PRC.

2 Summary of significant accounting policies and practices(Continued)



(t) Recently issued accounting standards

SFAS No. 157

In September 2006, the FASB issued SFAS No. 157, Fair Value
Measurement. SFAS No. 157 defines fair value, establishes a framework for the measurement of fair value, and enhances disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measures. SFAS 157 is
effective for fair value measures already required or permitted by other standards for fiscal years beginning after November 15, 2007. The Group is required to adopt SFAS No. 157 beginning on January 1, 2008. The Group is currently
evaluating the impact of adopting SFAS No. 157 on its results of operations and financial position.

FASB Interpretation
No. 48 (FIN 48)

In July 2006, the FASB issued FIN 48, Accounting for Uncertainty in Income Taxesan
Interpretation of FASB Statement No. 109. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprises financial statements and prescribes a threshold of more-likely-than-not for recognition of tax
benefits of uncertain tax positions taken or expected to be taken in a tax return. FIN 48 also provides related guidance on measurement, derecognition, classification, interest and penalties, and disclosure. The provisions of FIN 48 are effective
for the Group from January 1, 2007. The adoption of FIN 48 had no impact on the Groups results of operations and financial position (note 17).

SFAS No. 159

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for
Financial Assets and Financial LiabilitiesIncluding an Amendment of FASB Statement No. 115 (SFAS No. 159). SFAS No. 159 permits an entity to elect fair value as the initial and subsequent measurement attribute
for many financial assets and liabilities. Entities electing the fair value option would be required to recognize changes in fair value in earnings. Entities electing the fair value option are required to distinguish, on the face of the balance
sheet, the fair value of assets and liabilities for which the fair value option has been elected and similar assets and liabilities measured using another measurement attribute. The Group is required to adopt SFAS No. 159 beginning on
January 1, 2008. The adjustment to reflect the difference between the fair value and the carrying amount would be accounted for as a cumulative-effect adjustment to retained earnings as of the date of initial adoption. The Group has determined
not to adopt the fair value option for existing eligible items as of January 1, 2008.

SFAS No. 160

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statementsan Amendment of ARB
No. 51. SFAS No. 160 establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. Among other requirements, the new standard will result in the presentation
of the what are currently considered minority interests to be classified as equity. The guidance will become effective for the fiscal year beginning after December 15, 2008. The Group is in the process of evaluating the impact SFAS No. 160
will have on the Groups consolidated financial statements upon adoption.

Prepayments as of December 31, 2006 and 2007 include an amount of RMB353,000 and RMB353,000
(US$48,000) respectively, representing the current portion of lease prepayments of the Group (note 9).

Other receivables mainly include
staff advances and other miscellaneous receivables.

6 Structured deposit

During the year ended December 31, 2007, the Group acquired zero coupon equity-linked notes (ELNs) issued by a financial institution
which mature in June 2008. The ELNs include an embedded derivative with the characteristics similar to a written-put option of shares, which entitles the Group to a higher fixed rate of return from the deposit but in return would require the Group
to purchase the share of an entity listed in the Hong Kong Stock Exchange at a pre-determined price in the event the market price is lower than the pre-determined price of the share at maturity date. The embedded derivative is considered not closely
related to the host contract. The Company has elected to measure the ELNs as a single financial instrument, rather than as a debt security host and separate derivative instrument. Accordingly, the ELNs are stated at fair value with remeasurements to
fair value recognized as other income/loss. Unrealized loss of RMB10,000 (US$1,000) has been charged to income for the year ended December 31, 2007.

Corporate debt securities are interest-bearing at 5-6% per annum and are listed outside the
PRC. The amount will mature and be repayable from 2010 to 2017. Structured notes represent callable range accrual notes issued by a financial institution at par which have a ten-year term and carry interest at 7%, if the market interest rate,
3-month US$ LIBOR, is lower than 7%. The interest rate will be nil if the 3-month US$ LIBOR is higher than 7%. Interest income is measured and paid quarterly. The issuer of the structured notes has an option to redeem the structured notes at par at
the end of each quarter through the maturity date of the notes. The embedded derivative included in the structured notes is considered clearly and closely related to the debt host and as such the structure notes are measured at amortized cost with
interest income being recognized using the retrospective interest method.

authorized share capital of 50,000 ordinary shares at par value of US$1 each. Pursuant to an ordinary resolution passed on September 5, 2006, the authorized share capital of US$50,000 was divided into 500,000,000 ordinary shares at par value of
US$0.0001 each and accordingly, the issued share capital of US$1 was divided into 10,000 ordinary shares at par value of US$0.0001. In connection with the Reorganization described in note 1(b), on September 5, 2006, the Company issued
99,990,998 ordinary shares at par on a pro-rata basis to the ultimate beneficial shareholders of Collected Mind or their nominees as consideration for the acquisition of Collected Mind. The issue of the 99,990,998 ordinary shares at par resulted in
a capital contribution of approximately RMB80,000 by the shareholders.

During the year ended December 31, 2007 the Company issued
52,083,157 new ordinary shares in connection with the IPO (note 1(a)).

(b) Statutory reserves(Continued)



Details of the statutory reserves are set out as follows:

Statutory surplus reserve

According to the respective Articles of Association, Shenyang Sunshine and its subsidiaries are required to transfer 10% of the net profit, as determined
in accordance with PRC GAAP, to a statutory surplus reserve until the reserve balance reaches 50% of the registered capital of the respective companies. The transfer to this reserve must be made before distribution of dividends to shareholders can
be made.

The statutory surplus reserve is non-distributable but can be used to make good previous years losses, if any, and may be
converted into share capital by the issue of new shares to shareholders in proportion to their existing shareholdings or by increasing the par value of the shares currently held by the shareholders, provided that the balance of the reserve after
such issue is not less than 25% of the registered capital.

Statutory public welfare fund

According to the respective Articles of Association, Shenyang Sunshine and its subsidiaries are required to transfer 5% of the net profit, as determined
in accordance with PRC GAAP, to a statutory public welfare fund. This fund can only be utilized on capital items for the collective benefit of the employees such as the construction of dormitories, canteen and other staff welfare facilities. This
fund is non-distributable other than on liquidation. The transfer to this fund must be made before distribution of dividends to shareholders can be made.

No transfer was made for the year ended December 31, 2005, 2006 and 2007 by Shenyang Sunshines subsidiaries as they had accumulated losses in the local statutory financial statements, prepared in accordance
with PRC GAAP, as of December 31, 2005, 2006 and 2007. Transfers of RMB1,416,000, RMB1,751,000 and RMB3,962,000 (US$543,000) have been made to the reserves by Shenyang Sunshine for the years ended December 31, 2005, 2006 and 2007,
respectively. As the requirement to transfer net profit to the statutory reserves applies only to Shenyang Sunshine and its subsidiaries but not the Company, statutory reserves of Shenyang Sunshine have been reclassified and included in accumulated
deficit or retained earnings upon the Reorganization described in note 1(b).

The accumulated balances of these statutory reserves
maintained by the Companys PRC subsidiaries as of December 31, 2006 and 2007 were RMB4,017,000 and RMB7,979,000 (US$1,094,000) respectively.

In accordance with PRC rules and regulations, effective from April 1, 2006, the statutory public welfare fund is transferred to statutory surplus reserve in the local statutory financial statements.

Shenyang
Sunshine, being a foreign-invested manufacturing enterprise in the Shenyang Economic and Technology Development Zone in Liaoning Province, the PRC, has been granted a preferential tax treatment by the State Tax Bureau of the PRC. According to the
PRC Income Tax Law and various approval documents issued by the Tax Bureau, Shenyang Sunshines profit has been taxed at a rate of 15%. In 2005, Shenyang Sunshine obtained the recognition as a foreign-invested advanced technology
enterprise, pursuant to which Shenyang Sunshine is granted a further 50% tax relief (subject to a minimum tax rate of 10%) for 2005. As a result, the applicable tax rate for 2005 was 10% while the tax rate for 2006 and 2007 was 15%.

Liaoning Sunshine and Beijing Sunshine, which are engaged in the distribution of pharmaceutical products, were subject to a tax rate of
33% for the years ended December 31, 2005, 2006 and 2007.

PRC Tax(Continued)



On
March 16, 2007, the Fifth Plenary Session of the Tenth National Peoples Congress passed the Corporate Income Tax Law of the PRC (the new tax law) which will take effect on January 1, 2008. Further, on December 6,
2007, the State Council released the Implementation Rules to the Corporate Income Tax Law (the implementation rules). According to the new tax law, from January 1, 2008 the applicable corporate income tax rates for enterprises in
the PRC will be reduced from 33% to 25%. Under the new tax law being effective from January 1, 2008 and in accordance with Notification of the State Council on Carrying out the Transitional Preferential Policies concerning Corporate
Income Tax (Guo Fa [2007] No.39) issued by the State Council on December 26, 2007, an entity established before March 16, 2007 that was entitled to preferential tax treatment prior to the new tax law will be subject to a transitional
tax rate beginning in period 2008 (Transitional Tax Rate) before the new corporate income tax rate of 25% applies. The Transitional Tax Rate is 18%, 20%, 22%, 24% and 25% in 2008, 2009, 2010, 2011 and 2012 onwards respectively.

On April 14, 2008, the Ministry of Science and Technology, the Ministry of Finance and the State Administration of Taxation jointly
issued the Administrative Measures for Recognition of New and Advanced Technology Enterprises which provides the new recognition criteria and procedures for an encouraged high-tech enterprise to be entitled to a reduced
corporate income tax rate of 15%. It is uncertain Shenyang Sunshine could qualify as a new and advanced technology enterprise, and the income tax rate for Shenyang Sunshine is expected to increase to the standard rate of 25% over a 5-year transition
period effective from January 1, 2008 as stated above.

The enactment of the new tax law is not expected to have any financial effect
on the amounts accrued in the balance sheet in respect of current tax payable. The deferred tax assets of Shenyang Sunshine are measured using enacted tax rates expected to apply to taxable income, based on the Transitional Tax Rate, in the years in
which those temporary differences are expected to be recovered or settled. Liaoning Sunshine and Beijing Sunshine are expected to be subject to a reduced income tax rate of 25% commencing from January 1, 2008. The reduction in the applicable
tax rates for Liaoning Sunshine and Beijing Sunshine from 33% to 25% is expected to have no net impact on the Groups deferred tax assets as full valuation allowance has been made against the balance of net deferred tax assets.

Income tax expense/(benefit) represents PRC income tax as follows:

In assessing the realizability of deferred tax assets, management considers whether it is more
likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary
differences become deductible and tax carryforwards are utilizable. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon an
assessment of the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible or can be utilized, management has provided valuation allowance of RMB2,381,000 and
RMB1,553,000 (US$213,000) as of December 31, 2006 and 2007 respectively. Full valuation allowance is provided for loss making subsidiaries of the Company since it is more likely than not that the net deferred tax assets would not be realized.
Management believes that the deferred

tax asset, less valuation allowance made, as of December 31, 2006 and 2007 is more likely than not to be realized. The amount of the deferred tax asset
considered realizable, however, could be reduced in the near term if estimates of future taxable income are reduced.

In June 2006, the
FASB issued FIN 48, which, among other things, requires the application of a more likely than not threshold to the recognition and derecognizing of tax positions. Effective January 1, 2007, the Group adopted FIN 48. As of the date
of the adoption of FIN 48, the Group has no material unrecognized tax benefit which would favorably affect the effective income tax rate in future periods and does not believe there will be any significant increases or decreases within the next
twelve months. 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 and comprehensive income. No interest or
penalties have been accrued at the date of adoption. According to the PRC Tax Administration and Collection Law, the statute of limitations is three years from 2005 to 2007 if the underpayment of taxes is due to computational errors made by the
taxpayer or the withholding agent. The statute of limitations extends to five years from 2003 to 2007 under special circumstances, which are not clearly defined. In the case of a related party transaction, the statute of limitation is ten years from
1998 to 2007. There is no statute of limitation in the case of tax evasion.

18 Share-based compensation

(a) Shares granted to executives

On
June 1, 2006, Shenyang Keweier committed to grant shares of the Company to a director and a senior executive of the Company as compensation for their on-going services rendered to the Company. The Companys intent is to provide
compensation to each grantee in a predetermined amount based on US$277,778 per award to be paid in the form of the Companys shares. The shares vest upon the earlier of (1) 18 months from June 1, 2006 or (2) on the date of the
Companys IPO. Should the date of the IPO fall within 18 months from June 1, 2006, the number of vested shares to be granted to each of the grantees would be calculated by dividing a predetermined monetary amount of US$277,778 by the fair
value per share on the IPO date. The number of vested shares to be granted was calculated based on a revised monetary amount that was adjusted proportionately to reflect the excess of the market capitalization at the IPO date of the Company over
US$222 million. In the event that the IPO did not occur within 18 months from June 1, 2006, a total number of 312,504 vested shares of the Company would be granted. Subsequent to the Reorganization described in Note 1(b), the ultimate
shareholders of Shenyang Keweier hold shares of the Company via Achieve Well International Limited (Achieve Well), and Achieve Well transferred shares of the Company to the director and executive upon vesting.

In accordance with SFAS No.123R, since the share awards contained vesting and exercisability conditions other than those based on service, performance or
market criteria, the awards were classified as a liability and were initially measured at the estimated fair value of the shares expected to vest at the grant date and were subject to remeasurement at each reporting date.

On October 15, 2006, the stock awards were modified and settled, with Achieve Well granting an aggregate of 312,504 fully vested ordinary shares of
the Company to the two individuals. The stock awards ceased to be liability-classified and were reclassified as equity upon settlement. The fair value of the modified awards as of the settlement date of approximately RMB1,877,000 (US$241,000) was
charged to the consolidated statement of

income and comprehensive income for the year ended December 31, 2006 with a corresponding increase in additional paid-in capital. The fair value of the
awards as of the settlement date was estimated based on the transaction price of a recent private sale of shares by a shareholder of the Company to unrelated third parties.

On August 9, 2006, the Company granted 15,000 shares to a senior executive of the Company for her on-going services rendered to the Company. The
fair value of the shares at grant date was RMB90,000. The shares vested on July 31, 2007 and were issued to the employee during the year. The Company recognized compensation expense of RMB38,000 and RMB52,000 (US$7,000), respectively, for the
years ended December 31, 2006 and 2007 in respect of these shares.

(b) Share options granted to executives

On September 5, 2006, the Company adopted the 2006 stock incentive plan (the Plan) pursuant to which the Board of Directors grants share
options and shares of the Company to directors and employees. Under the Plan, shares and options to purchase shares up to 10% of the issued shares of the Company can be granted. The Plan will remain in effect for five years from the date of
adoption.

On October 1, 2006, the Company granted several directors and employees options (October 2006 options) to
purchase a total of 1,060,000 ordinary shares of the Company at an exercise price of US$1.60 per share. The vesting dates of the options granted are as follows:



|                   |  |                 
|------------------ |  | ----------------
|Vesting date       |  | Numberof options

|September 30, 2007 |  | 333,333         
|December 31, 2007  |  | 45,000          
|September 30, 2008 |  | 333,333         
|September 30, 2009 |  | 333,334

|                   |  |                 

All the above options granted are exercisable by the grantees upon vesting and will expire on
October 1, 2009.

On July 23, 2007, the Company granted options to a senior executive (July 2007 options) for the
purchase of a total of 100,000 ordinary shares of the Company at an exercise price of US$1.60 per share. The July 2007 options become exercisable on May 31, 2008 and expire on June 1, 2010.

No options were exercised or forfeited during the year ended December 31, 2007.

The aggregate intrinsic value in the table above represents the difference between the
Companys closing stock price on the last trading day in 2007 and the exercise price.

The fair value of each option award is
estimated on the date of grant using the Black-Scholes option pricing model based on the following assumptions:

Up to the date of grant of the October 2006 options, the Companys shares were not publicly
traded and did not have a quoted market price. As a result, for the purpose of share option valuation, the fair value of the Companys shares was estimated based on the transaction price of a recent private placement of shares by a shareholder
of the Company with unrelated third parties valued at RMB6 per share.

For the July 2007 options and the purpose of share option valuation,
the fair value of the Companys shares was estimated based on the quoted market price of the Companys ADSs listed on The Nasdaq Global Market at the grant date.

The historical volatility of the Companys shares and volatility of a combination of peer companies of similar nature and size were used to estimate
the volatility of the Companys shares. The Company uses historical data to estimate employee termination within the valuation model. The risk-free rate for periods within the contractual life of the options is based on the U.S. government bond
in effect at the time of grant. Expected dividend yields are based on historical dividends. Changes in these subjective input assumptions could materially affect the fair value estimates.

20 Pension and other postretirement benefits

Pursuant to the relevant PRC regulations, the Companys PRC subsidiaries is required to make contributions for each employee at a rate of approximately 20% on a standard salary base as determined by the local Social Security Bureau, to
a defined contribution retirement scheme organized by the local Social Security Bureau in respect of the retirement benefits for the Groups employees in the PRC. The total amount of contributions of RMB1,224,000, RMB1,330,000 and RMB1,475,000
(US$202,000) for the years ended December 31, 2005, 2006 and 2007 respectively, was charged to expense in the consolidated statements of income and comprehensive income. The Group has no other obligation to make payments in respect of
retirement benefits of the employees.

21 Fair value of financial instruments

The fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties. The
carrying amount of financial assets, such as cash and cash equivalents, accounts receivable, other receivables, accounts payable and other payables, approximates their fair values because of the short maturity of these instruments. The carrying
amount of bank loans approximates their fair values based on the borrowing rates currently available for bank loans with similar terms and maturities.
