D. Risk Factors.

An investment in our ADSs involves significant risks. The risks and uncertainties described below are not the only ones we face. You
should consider carefully all of the information in this annual report, including the risks and uncertainties described below and our consolidated financial statements and related notes, before making an investment in our ADSs. Any of the following
risks could have a material adverse effect on our business, financial condition and results of operations. In any such case, the market price of our ADSs could decline, and you may lose all or part of your investment.

The global financial crisis may have further material adverse effects on our financial condition and operating results.

The global financial crisis has resulted in reduced demand and decreased prices for the petrochemical industry. Although the
Chinese government has taken measures to stabilize the macroeconomic environment and the Chinese economy maintained some growth as a result of the economic stimulus packages implemented by the Chinese government in 2009, it is not clear if and when
economic growth in China will be as strong as it was in the past. Chinas petrochemical industry is confronted with substantial difficulties and challenges. The uncertainty as to when certain economic stimulus policies will be revoked and the
growth trend of international trade may continue to have an adverse impact on our operating results.

Our operations may be
adversely affected by the cyclical nature of the petroleum and petrochemical market and by the volatility of prices of crude oil and petrochemical products.

Most of our revenues are attributable to petrochemical products, which have historically been cyclical and sensitive to the availability
and price of raw materials and general economic conditions. Markets for many of our products are sensitive to changes in industry capacity and output levels, cyclical changes in regional and global economic conditions, the price and availability of
substitute products and changes in consumer demand, which from time to time have had a significant impact on product prices in the regional and global markets. Historically, the markets for these products have experienced alternating periods of
tight supply, causing prices and margins to increase, followed by periods of capacity additions, finally resulting in oversupply and declining prices and margins. As tariffs and other import restrictions are reduced and the control of product
pricing is relaxed in China, the markets for many of our products have become increasingly subject to the cyclicality of regional and global markets.

Historically, international prices of crude oil have also fluctuated widely due to many
factors beyond our control. For example, international crude oil prices increased significantly in the first half of 2009 after reaching a low for the year of US$33.98 per barrel on February 12. In the second half, prices remained volatile and
fluctuated at a relatively high level, rallying between US$70 ~ US$80 per barrel and rising to an all-year high closing price of US$81.18/barrel on October 22. As crude oil costs accounted for RMB26,450 million or 58.76% of the Groups
annual cost of sales in 2009, changes in crude oil prices can affect the Groups profitability. We expect that the volatility and uncertainty of the prices of crude oil and petrochemical products will continue, and that increasing crude oil
prices and declines in prices of petrochemical products may adversely affect our business and results of operations and financial condition.

Some of our major products are subject to government price controls, and we are not able to pass on all cost increases from rising
crude oil prices through higher product prices.

We consume large amounts of crude oil to manufacture our products of
which more than 90% is imported. We attempt to mitigate the effect of increased costs due to rising crude oil prices. However, our ability to pass on these increased costs to our customers is dependent on market conditions and government
regulations, particularly government regulation with respect to the price of certain of our fuel products. In particular, gasoline, diesel and jet fuel, and liquefied petroleum gas are subject to government price controls. In 2007, 2008 and 2009,
approximately 54.06%, 43.52% and 47.70% of our net sales were from such products subject to price control. Although we do receive subsidies from the Chinese government to, among other things, cover part of our losses resulting from such price
controls, the amount of such subsidies vary substantially from year to year or even quarter to quarter and is difficult to predict. Although the Chinese government has adopted a new pricing mechanism for domestic refined oil products that indirectly
links the prices of these products to international crude oil prices (see Item 4. Information on the Company  B. Business Overview  Product Pricing), such pricing mechanism is still nontransparent. Moreover, the Chinese
government controls the distribution of many petroleum products in China. For instance, some of our petroleum products are required to be sold to designated distributors (such as the subsidiaries of China Petroleum & Chemical Corporation).
Because we cannot freely sell our fuel products to take advantage of opportunities for higher prices and because the formula for the new pricing mechanism set by the Chinese government is not transparent, in periods of high crude oil prices, we may
not be able to fully cover increases in crude oil prices by increases in the sale prices of our products, which has had and will continue to have a material adverse effect on our financial condition, results of operations and cash flows.

Our development and operation plans have significant capital expenditure and financing requirements, which are subject to a number of
risks and uncertainties.

The petrochemical business is a capital intensive business. Our ability to maintain and increase
our revenues, net income and cash flows depends upon continued capital spending. Our current business strategy contemplates capital expenditures for 2010 of approximately RMB2.0 billion (US$293 million), which will be provided through financing
activities and use of our own capital. Our actual capital expenditures may vary significantly from these planned amounts due to our ability to generate sufficient cash flows from operations, investments and other factors that may be beyond our
control. In addition, there can be no assurance as to whether, or at what cost, our capital projects will be completed or the success of these projects if completed.

As a result of the global economic downturn and its negative effect on our net income and cash flows, we have had to take on an increased
amount of indebtedness in 2008, 2009 and 2010 to fund our capital expenditures and operations as compared to previous years. As of March 31, 2010, we had aggregate outstanding indebtedness of approximately RMB8.093 billion (US$1.186 billion).
Most of our loans are with state-controlled banks in China and structured as short-term debt obligations with payment due in one year or less. These banks have generally been willing to provide new short-term loans while we pay down existing loans,
as our overall debt level has been reduced slightly since 2008. China Petroleum & Chemical Corporation (Sinopec Corp), our controlling shareholder, did not provide any guarantee or credit support for our debt for the year ended
December 31, 2009 and for the three-month period ended March 31, 2010.

Our ability to obtain external financing in
the future and our ability to make timely repayments of our debt obligations are subject to a variety of uncertainties, including:              our future results of operations, financial
condition and cash flows;              the condition of the economy in China and the markets for our products;              the
cost of financing and the condition of financial markets; the issuance of relevant government approvals and other project risks associated with the development of infrastructure in China; and the continuing willingness of banks to provide new loans
as we pay down existing debt.

While we anticipate that we will rely less on debt to finance capital expenditures and
operations as the global economic outlook begins to improve, if we fail to obtain sufficient funding for our operations or development plans or are unable to obtain new short-term debt to pay off existing debt, our business, results of operations
and financial condition could be adversely affected.

We could face increased competition.

Our principal market, Eastern China, which is comprised of Shanghai, Jiangsu, Zhejiang, Anhui and Jiangxi, has enjoyed stronger economic
growth and a higher demand for petrochemical products than other regions of China. As a result, we believe that competitors will try to expand their sales and build up their distribution networks in our principal market. In 2010, we expect that
Chinas petrochemical market will reach a peak in newly built on stream capacity. The commencement of production by new plants will continue to create a capacity surplus and result in a structural oversupply in the petrochemical market in
general. We believe this will have a substantial adverse impact on the production and sale of our major products. Moreover, Chinese private enterprises have gradually overcome technological and funding barriers to extend their business from the
downstream processing sector to the upstream petrochemical field. These enterprises have advantages in many areas such as flexibility in operation costs, preferential policy treatment and regional presence, and may use these advantages to compete
with us in markets for our products.

Related party transactions; non-competition; conflicts of interests.

We have engaged from time to time and will continue to engage in a variety of transactions with Sinopec Corp and China Petrochemical
Corporation, the controlling shareholder of Sinopec Corp, and their various subsidiaries or affiliates who provide a number of services to us, including the supply of raw materials, product distribution and sales agency, project design and
installment service. Our transactions with these companies are governed by a Mutual Product Supply and Sales Services Framework Agreement with Sinopec Corp and a Comprehensive Services Framework Agreement with Sinopec Group, the terms of which were
negotiated on an arms length basis, see Item 7. B. Related Party Transactions  Intercompany Service Agreement and Business-related Dealings. Our business and results of operations could be adversely affected if Sinopec Corp
refuses to engage in such transactions or if it seeks to amend the contracts between the parties in a way adverse to us. In addition, Sinopec Corp has interests in businesses which compete or are likely to compete, either directly or indirectly,
with our businesses. Because Sinopec Corp is our controlling shareholder and its interests may conflict with our own interests, Sinopec Corp may take actions that favor itself over our interests.

We are controlled by Sinopec Corp, whose interests may not be aligned with yours.

As of May 1, 2010, Sinopec Corp owned 55.56% of our shares. Accordingly, it has voting and management control over us, and its
interests may be different from your interests and the interests of our other shareholders. Subject to our Articles of Association and applicable laws and regulations, Sinopec Corp will be in a position to cause us to declare dividends, determine
the outcome of corporate actions requiring shareholder approval or effect corporate transactions without the approval of the holders of the H shares and ADSs. Any such increase in our dividend payout would reduce funds available for reinvestment in
our business and any such actions or transactions could adversely affect us or our minority shareholders. Additionally, Sinopec Corp may experience changes in its own business strategy and policies. Although we are not currently aware of any
specific changes, they could, in turn, lead Sinopec Corp to change its policies or practices toward us in ways that we cannot predict, with corresponding unpredictable consequences for our business.

Our business operations may be adversely affected by present or future environmental regulations.

We are subject to extensive environmental protection laws and regulations in China. These laws and regulations permit:



| |  |  | the imposition of fees and penalties for the discharge of waste substances;
| | - |  | ---------------------------------------------------------------------------



| |  |  | the levy of fines and payments for damages for environmental offenses; and
| | - |  | --------------------------------------------------------------------------



| |  |  | the government to close or suspend any facility which fails to comply with orders and require it to correct or stop operations causing environmental
damage.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------

Our production operations produce substantial amounts of waste materials. In addition, our
production and operations require permits that are subject to renewal, modification and revocation. At present, we believe that our operations substantially comply with all applicable Chinese environmental laws and regulations as they have been
previously interpreted and enforced. The Chinese government, however, has moved, and may move further, toward more rigorous enforcement of applicable laws, and toward the adoption of more stringent environmental standards. Chinese national or local
authorities may also impose additional regulations or apply more rigorous enforcement of such regulations which would require additional expenditures on environmental matters.

Our business may be limited or adversely affected by government regulations.

The central and local Chinese governments continue to exercise a certain degree of control over the petrochemical
industry in China by, among other things:



| |  |  | mandating distribution channels for our fuel products;
| | - |  | ------------------------------------------------------



| |  |  | setting the allocations and pricing of certain resources, products and services;
| | - |  | --------------------------------------------------------------------------------



| |  |  | assessing taxes and fees payable;
| | - |  | ---------------------------------



| |  |  | setting import and export quotas and procedures; and
| | - |  | ----------------------------------------------------



| |  |  | setting safety, environmental and quality standards.
| | - |  | ----------------------------------------------------

As a result, we may face significant constraints on our flexibility and ability to expand our business operations or to maximize our
profitability. In the past, we have benefited from favorable regulatory policies that have, for example, reduced the competition we face from illegal imports of petroleum products. Existing policies that favor our industry may change in the future
and our business could be adversely affected by any such changes.

Our development plans may require regulatory approval.

We are currently engaged in a number of construction and expansion projects. Most of our projects are subject to
governmental review and approval. The timing and cost of completion of these projects will depend on numerous factors, including approvals from relevant government authorities and general economic conditions in China.

While in general we attempt to obtain governmental approval as far in advance as practicable, we may not be able to control the timing
and outcome of these governmental reviews and approvals. If any of our important projects required for our future growth are not approved, or not approved on a timely basis, our results of operations and financial condition could be adversely
affected.

Chinas entry into the World Trade Organization, or WTO, may significantly increase foreign competition in
our lines of business.

China joined the WTO on December 11, 2001. As part of its membership, China has committed to
eliminate some tariff and non-tariff barriers to foreign competition in the domestic petrochemical industry that benefited us in the past. In particular, China:



| |  |  | has reduced tariffs on imported petrochemicals products that compete with ours;
| | - |  | -------------------------------------------------------------------------------



| |  |  | increased levels of permitted foreign investment in the domestic petrochemicals industry, allowing foreign investors to own 100% of a domestic
petrochemicals company from December 11, 2004;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | has gradually relaxed restrictions on the import of crude oil by non-state owned companies;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | has granted foreign-owned companies the right to import petrochemical products; and
| | - |  | -----------------------------------------------------------------------------------



| |  |  | has permitted foreign-owned companies to distribute and market fuel products in both retail and wholesale markets in China.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------

As a result of these measures, we face increased competition from foreign companies and imports. In 2010,
the impact of the global economic downturn will continue, the global market for petrochemical products may be slow to recover, and many overseas petrochemical companies, in particular those from neighboring areas, such as Japan, South Korea and the
Middle East, have switched their focus to sales in China, which we believe, will further intensify competition in the Chinese domestic petrochemical market. In addition, tariff reductions could reduce our profit margins or otherwise negatively
impact our revenue from certain products, including a small number of significant products. The PRC government may also reduce the tariffs imposed on production equipment that we may import in the future.

Political and economic policies in China could affect our business in unpredictable ways.

The economy of China differs from the economies of most countries belonging to the Organization for Economic Co-operation and Development
in a number of respects, including:



| |  |  | structure;
| | - |  | ----------



| |  |  | level of government involvement;
| | - |  | --------------------------------

| |  |  | level of development;

| |  |  | level of capital reinvestment;
| | - |  | ------------------------------



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



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

Before its adoption of reform and open-door policies beginning in 1978, China was primarily a planned economy. Since that time, the
Chinese government has been reforming the Chinese economic system, and has also begun reforming the government structure. These reforms have resulted in significant economic growth and social progress. Although the Chinese government still owns a
significant portion of the productive assets in China, economic reform policies since the late 1980s have emphasized autonomous enterprises and the utilization of market mechanisms. We currently expect that the Chinese government will continue these
reforms, further reduce government intervention and rely more heavily on market mechanisms to allocate resources. Although we believe these reforms will have a positive effect on our overall long-term development, we cannot predict whether changes
to Chinas political, economic and social conditions, laws, regulations and policies will have any adverse effect on our current or future business or results of operations.

If the Chinese government changes current regulations that allow us to make payments in foreign currencies, we may be unable to obtain
the foreign currency which is necessary for our business.

The Renminbi currently is not a freely convertible currency. We
receive most of our revenue in Renminbi. A portion of our Renminbi revenue must be converted into other currencies to meet our foreign currency obligations. We have substantial requirements for foreign currency, including:



| |  |  | debt service costs on foreign currency-denominated debt;
| | - |  | --------------------------------------------------------



| |  |  | purchases of imported equipment;
| | - |  | --------------------------------



| |  |  | payment of any cash dividends declared in respect of the H shares; and
| | - |  | ----------------------------------------------------------------------



| |  |  | import of crude oil and other materials.
| | - |  | ----------------------------------------

Under existing foreign exchange regulations in China, we may undertake current account foreign exchange transactions, including the
payment of dividends, without prior approval from the State Administration of Foreign Exchange by producing commercial documents evidencing the foreign exchange transactions, provided that they are processed through Chinese banks licensed to engage
in foreign exchange transactions. The Chinese government has stated publicly that it intends to eventually make the Renminbi freely convertible in the future. However, uncertainty exists as to whether the Chinese government may restrict access to
foreign currency for current account transactions if foreign currency becomes scarce in China.

Foreign exchange transactions
under the capital account (international revenues and expenditures that increase or decrease debt or equity, including principal payments in respect of foreign currency-denominated obligations) continue to be subject to limitations and require the
prior approval of the State Administration of Foreign Exchange. These limitations could affect our ability to obtain foreign exchange through debt financing, or to make capital expenditures in foreign currency.

If the Chinese government restricts our ability to make payments in foreign currency, we may be unable to obtain the foreign currency
which is necessary for our business. In that case, our business may be materially adversely affected, and we may default on our obligations.

The rejection of the proposed share reforms required of companies listed on the Shanghai
Stock Exchange may adversely affect our market image and our ability to effectuate future transactions such as public offerings on the Shanghai Stock Exchange.

Pursuant to regulations issued by the China Securities Regulatory Commission (the CSRC), we were required to gain shareholder
approval for and implement certain share reforms in 2006. Under the share reform plans proposed by holders of our non-circulating A Shares in 2006 and 2007, respectively, all non-circulating A Shares would be converted into circulating A Shares and
may be sold publicly on the Shanghai Stock Exchange subject to any applicable lock-up period under the condition that holders of our non-circulating A Shares transfer a portion of their A Shares to holders of our circulating A Shares. However,
holders of our circulating A Shares rejected both share reform plans. No specific new proposals have yet been presented to implement the required share reforms. We are uncertain as to when such share reforms will be completed. On January 8,
2007, the Shanghai Stock Exchange began to impose stricter regulations on its listed companies that are required but unable to complete the share reforms, including stricter trading information disclosure requirements and greater restrictions on
their ability to effectuate future public offerings. Since March 26, 2007, the Shanghai Stock Exchange has required us to make periodically public announcements regarding the status of our share reforms. In addition, the CSRC is expected to
more strictly scrutinize any securities-related applications by publicly listed PRC companies that are required to but have failed to complete such share reforms, their major shareholders and ultimate beneficial owners. The rejection of the proposed
share reforms by the holders our circulating A Shares may adversely affect our market image and our ability to effectuate future transactions such as public offerings on the Shanghai Stock Exchange. The possibility that the CSRC and the Shanghai
Stock Exchange will impose more restrictions cannot be eliminated.

Interpretation and enforcement of Chinese laws and
regulations is uncertain.

The Chinese legal system is based on statutory law. Under this system, prior court decisions
may be cited as persuasive authority, but do not have the binding effect of precedents. Since 1979, the Chinese government has been developing a comprehensive system of commercial laws and considerable progress has been made in the promulgation of
laws and regulations dealing with economic matters, such as corporate organization and governance, foreign investment, commerce, taxation and trade. Because these laws, regulations and legal requirements are relatively new and not all accessible to
the public and because prior court decisions have little precedential value, the interpretation and enforcement of these laws, regulations and legal requirements involve greater uncertainty than in other jurisdictions.

You may not enjoy shareholders protections that you would be entitled to in other jurisdictions.

As most of our business is conducted in China, our operations are governed principally by the laws of China. Despite changes to the PRC
Company Law, Chinese legal provisions for the protection of shareholders rights and access to information are different and less developed than those applicable to companies formed in the United States, Hong Kong, the United Kingdom and other
developed countries or regions. You may not enjoy shareholders protections under Chinese law that you would be entitled to in other jurisdictions.

Our Articles of Association require you to submit your disputes with us and other persons to arbitration. You will have no legal right
to a court proceeding.

Our Articles of Association require holders of our H shares or ADSs having a claim against, or a
dispute with, us, our directors, supervisors, executive officers or a holder of our domestic shares relating to any rights or obligations conferred or imposed by our Articles of Association, the Chinese Company Law or any other Chinese laws or
regulations relating to our affairs, to submit such claim or dispute to arbitration with the China International Economic and Trade Arbitration Commission or to the Hong Kong International Arbitration Center. Our Articles of Association further
provide that any arbitration decisions with respect to such disputes or claims shall be final and binding on all parties.

We may be or become a passive foreign investment company, which could result in adverse
U.S. federal income tax consequences to U.S. investors.

We may be classified as a passive foreign investment company
(PFIC) by the U.S. Internal Revenue Service for U.S. federal income tax purposes. Such characterization could result in adverse U.S. federal income tax consequences to you if you are a U.S. investor. For example, U.S. investors who owned
our ADSs during any taxable year in which we were a PFIC generally are subject to increased U.S. tax liabilities and reporting requirements for that taxable year and all succeeding years, regardless of whether we actually continue to be a PFIC,
although a shareholder election to terminate such deemed PFIC status may be available in certain circumstances. The same adverse U.S. federal income tax consequences will apply to U.S. investors who acquire our ADSs during the current taxable year
or any subsequent taxable year if we are treated as a PFIC for that taxable year.

The determination of whether or not we are
a PFIC is made on an annual basis and depends on the composition of our income and assets, from time to time. Specifically, we will be classified as a PFIC for U.S. tax purposes for a taxable year if either (a) 75% or more of our gross income
for such taxable year is passive income, or (b) 50% or more of the average percentage of our assets during such taxable year either produce passive income or are held for the production of passive income. For such purposes, if we directly or
indirectly own 25% or more of the shares of another corporation, we generally will be treated as if we (a) held directly a proportionate share of the other corporations assets, and (b) received directly a proportionate share of the
other corporations income. 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 IRS will not challenge our determination concerning our PFIC status. For further discussion of the adverse U.S. federal income tax consequences of our possible classification as a PFIC, see
Taxation below.

Negative publicity regarding, and divestments by investors in response to, our affiliation
with Sinopec Corp. and Sinopec Group, and their respective activities in certain countries identified by the U.S. government as state sponsors of terror, may adversely impact our stock price.

We are affiliated with Sinopec Corp. and Sinopec Group, both of which have been identified in the news media as engaging in operations in
or purchasing substantial volumes of crude oil sourced from countries identified by the U.S. government as state sponsors of terrorism such as Iran, Syria, Cuba and Sudan. We do not conduct any material operations in, nor do we purchase any material
volume of crude oil from these countries. Further, we have no control over the activities of Sinopec Group or Sinopec Corp. in connection with any activities they may have related to Iran, Syria, Sudan or Cuba. Nevertheless, certain articles in the
press have identified institutional investors, many of whom have substantial investment portfolios and purchasing power, that may have divested, or intend to divest or otherwise not invest in, our stock because of the alleged operations of our
affiliates in such countries. Decisions by such large investors may have the effect of reducing demand for our stock in the market, perhaps significantly, which could cause substantial downward pressure on our stock price. Any such downward pressure
likely would result in a reduction of our market capitalization and could impact not only the value of our existing stockholders investment in our company, but also potentially our ability to raise equity or debt financing in the future.
